The feeding and gripping part of the carding machine includes cotton roller, cotton feeding roller, wrench mechanism, etc. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. The utility model has the functions of unwinding small rolls, feeding the cotton layer into the machine, grasping the cotton layer in time to comb the cylinder body, and releasing the pliers to transfer the carding layer to the jaws of the separating roller.
1. Cotton lap roller The cotton lap roller is used to maintain and unwind a small volume of solution to complete the feeding roller and nipper opening. There are two types of lap roller drives. 1. Intermittent transmission.
Figure 4-8 shows the A20tB carding machine lap roller automobile transmission system. The rocker 2 mounted on the nipper swing shaft 1 drives the L-shaped lever 4 to swing back and forth, and mechanically drives the lap roller and outputs the batt layer intermittently through the use of pawls, ratchets and gears. A pressing lever is tightly pressed on the two sides of the ratchet wheel, which can eliminate its inertial thinking rotation.
2. After the speed of the continuous drive carding machine is increased, inertial impact and noise will occur in the intermittent drive, so the lap roller of the modern high-speed carding machine has adopted a slow-speed continuous drive. However, the cotton feeding roller is rotated intermittently, and the cotton layer is fed regularly and quantitatively. Therefore, in order to keep the cotton layer free from wrinkling and elongation, a rotatable eccentric roller is set between the cotton lap roller and the cotton feeding roller to hold the cotton. layer, see Figure 4-9. When the cotton feeding roller 3 does not rotate, the large radius end of the eccentric roller 2 turns upward, which can store a certain length of cotton layer; when the cotton feeding roller 3 rotates, the large radius end of the eccentric cable turns downward, thus releasing this section again Cotton layer.
The guide plate 3 shown in Figure 4-3 can be bent and stretched with the front and rear swing of the pliers, and it also has the function of storing and adjusting. 2. Feeding roller The feeding roller can be rotated intermittently and regularly, and the cotton layer withdrawn by the lap roller company is transported to the lower nipper wrench lip for Xinjinlong to comb. The feeding roller is installed on the lower nipper. There are single roller and double roller as two different types in the structure design. For example, according to the feeding time, there are two main forms: forward feeding and backward feeding.
When the nipper moves forward, feeding cotton to the cotton roller is called forward feeding, and when the nipper moves backward, feeding cotton is called backward feeding. The output of A20I series carding machines is only in the form of forward feeding. However, FA2SI and FA261 type cards have both at the same time, and we can change the work immediately according to the needs of the enterprise to adapt to the transformation of various information spinning products in the society. needs. as the picture shows.
4-10 (I), the ratchet is fixed on the shaft head of the cotton roller, when the clamping plate swings forward, the upper clamping plate is in the opposite direction around the point K, so that the ratchet hooks the ratchet, thereby realizing the advance of the cotton. As shown in Fig. 4-10(2), due to the pinion driven by the sector gear, when the clamping plate retreats, the upper clamping plate rotates clockwise around the point K. Rotate the pawl support ratchet to achieve cotton return.
The number of ratchet teeth can be adjusted to cotton length.
