Abstract
Description
Technical Field
[0001] The utility model belongs to the field of cotton spreading machines, in particular to a rotary cotton spreading machine. Background Art
[0002] Cotton spreading machines are mainly used in the textile and garment industries. Their main function is to spread the cotton evenly on a substrate (such as cloth, cloth layers or other base materials) to achieve a predetermined thickness and density. This process of spreading the cotton evenly on the substrate can be automated, greatly improving production efficiency and product quality stability.
[0003] Existing cotton spreading machines may have problems of insufficient or excessive downward pressure when spreading cotton. Insufficient downward pressure of the drum will cause the cotton to be uneven and scattered and cannot be effectively formed. Excessive downward pressure will cause the cotton to be cake-shaped and have to be reprocessed, thereby wasting some cotton and causing unnecessary trouble. Utility Model Content
[0004] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a rotary cotton spreading machine to solve the problem of insufficient or excessive downward pressure when spreading cotton.

[0007] As a preferred technical solution, three limit blocks are fixedly installed on both sides of the base, and the limit blocks are located on the inner side of the support rod.
[0008] As an optimal technical solution, a second fixed plate is fixedly installed on one side of the upper end of the base, slots are opened on both sides of the second fixed plate, bearings are fixedly installed inside the slots, a screw is fixedly connected inside the bearing, and a knob is fixedly installed on the end of the screw away from the bearing.
[0009] As a preferred technical solution, one end of the sliding rod away from the top plate is rotatably connected to a pulley, and the pulley is rollingly connected in the rectangular groove.
[0010] As a preferred technical solution, one end of the limiting rod away from the top plate is rotatably connected to a second connecting rod, and the limiting rod is rotatably connected to the drum through the second connecting rod.
[0011] As a preferred technical solution, the width of the roller is consistent with the width of the heating plate.
[0012] As a preferred technical solution, one end of the first connecting rod away from the second connecting rod is connected to a fixing rod, and both ends of the fixing rod are fixedly connected to one end of the first connecting rod.
[0013] As an optimal technical solution, a spring is provided inside the sliding rod, one end of the spring is fixedly installed at the bottom of the sliding rod, and the other end of the spring is fixedly installed at one end of the telescopic rod. The telescopic rod moves up and down inside the sliding rod through the spring.
[0014] As a preferred technical solution, the screw is connected to a first fixing plate via threads, and a guide column is fixedly mounted on one end of the second fixing plate away from the screw, and the guide column is sleeved inside the first fixing plate.
[0015] In summary, the utility model mainly has the following beneficial effects:
[0016] First, when the roller is rolling and flattening the cotton, you can add weight blocks in the weight-gaining box to adjust the downward pressure of the roller. When the cotton needs to be stacked, add weight blocks to press the cotton evenly, which can improve the quality of the cotton. When the cotton does not need to be stacked, you can subtract the weight blocks. This allows the pressure of the roller to adapt to cotton of different thicknesses. The weight of the roller can be adjusted at will to adapt the roller to different thicknesses, which can solve the problem caused by pressure when flattening the cotton.
[0017] Second, when the cotton is being flattened, the first fixed plate and the second fixed plate will be used to clamp one end of the cotton for rolling. In this way, the cotton will not deviate, which can improve the efficiency of cotton pressing. The limit rod will also better improve the stability and flexibility of the roller during work, and will not cause the roller to deviate from the route, thus solving the trouble caused during work.

[0029] Principle and advantages of use: When using, spread the cotton on the heating plate 8, and the cotton should be pressed against the limit block 4 so that the cotton will be evenly distributed. Turn the knob 6 manually, and the screw 22 will rotate. One end of the screw 22 is fixedly installed inside the bearing 5. Since the bearing 5 is fixedly installed in the notches 25 on both sides of the second fixing plate 20, the screw 22 will not be separated or offset when it rotates. The screw 22 is connected to the first fixing plate 7 through a thread. When the knob 6 is turned, the first fixing plate 7 will move toward the second fixing plate 20, and then clamp one end of the cotton so that the cotton It can be fixed on the heating plate 8 without movement or deviation, which can improve the stability of the cotton and make the cotton pressed more evenly. The support rods 3 are fixedly installed on both sides of the base 2, and a rectangular groove 18 is opened inside the support rod 3.
