Description

Technical Field

[0001] This utility model relates to the field of hemp combing machine technology, specifically to a feeding mechanism for a hemp combing machine. Background Technology

[0002] A jute combing machine is a device used to comb jute fibers. Through mechanical action, it combs disordered jute fibers into parallel and uniform fiber bundles, thereby improving fiber utilization efficiency and product quality. During the combing process, jute raw materials need to be fed and conveyed. For example, patent document CN217807086U discloses a jute combing machine feeding mechanism. Before feeding, the feeding mechanism can pour jute fiber material into a carrying box using a feeding funnel and distribute it into three sets of storage tanks. The weight sensor can measure the mass of jute fiber stored in each set of storage tanks, which facilitates the subsequent adjustment and distribution of jute feeding amount according to the combing speed of the jute combing machine. Moreover, the jute combing machine is less likely to be clogged due to excessive feeding at one time.

[0003] However, even if the above-mentioned feeding mechanism is equipped with multiple chambers, the continuous feeding of raw materials causes significant friction between raw materials and between raw materials and the inner wall of the mechanism, which makes it easy for raw materials to become blocked at the discharge port. Furthermore, the continuous feeding of raw materials can easily lead to accumulation in subsequent processing devices, reducing processing efficiency. Utility Model Content

A push plate is rotatably sleeved on the rod wall of the support rods, and a limiting plate is contacted at the top of the push plate. The limiting plate is fixedly connected to the slider. The feed box is equipped with an intermittent feeding mechanism for feeding materials.

[0007] Preferably, the intermittent feeding mechanism includes a reciprocating motor, which is fixedly mounted on the outer wall of the guide box.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a feeding mechanism for a hemp combing machine.

[0019] This utility model provides, for example Figure 1-3 The feeding mechanism of a combing machine shown includes a guide box 1 and support feet 2 fixedly disposed on both sides of the bottom of the guide box 1. A guide pipe 3 is fixedly inserted through the top of the guide box 1. A feeding hopper 4 is fixedly connected to the top of the guide pipe 3. An mounting plate 5 is fixedly disposed on the upper end of the inner wall of the feeding hopper 4. A support frame 6 is fixedly disposed on the bottom of the mounting plate 5. A drive screw 7 is rotatably inserted inside the mounting plate 5. A slider 8 is threadedly sleeved on the rod wall of the drive screw 7. Corrugated protective tubes 21 are fixedly disposed on both sides of the slider 8. The opening of the corrugated protective tube 21 is fixedly connected to the inner wall of the support frame 6. The corrugated protective tube 21 is sleeved on the outside of the drive screw 7. The slider 8 is slidably sleeved on the outside of the support frame 6. Two symmetrically arranged support rods 9 are fixedly disposed on the outer wall of the support rods 9. A push plate 10 is rotatably sleeved on the rod wall of the support rods 9. A limiting plate 11 is contacted at the top of the push plate 10. The limiting plate 11 is fixedly connected to the slider 8.

[0020] In order to allow for intermittent feeding of raw materials and avoid overloading the carding machine by receiving too much material at once, while ensuring continuous and stable carding operations, such as... Figure 1-2 As shown, the inside of the guide box 1 is provided with an intermittent feeding mechanism for feeding materials. The intermittent feeding mechanism includes a reciprocating motor 12, which is fixedly mounted on the outer wall of the guide box 1. The output shaft passes through the guide box 1 and is fixedly mounted with a rotating rod 13. The end of the rotating rod 13 passes through the guide box 1. A feeding plate 14 is fixedly sleeved on the shaft wall of the rotating rod 13. The longitudinal section of the feeding plate 14 is circular. The outer wall of the feeding plate 14 is provided with multiple receiving grooves 15 that are evenly distributed axially. The bottom of the guide box 1 is provided with a discharge port. A fixed plate 16 is fixedly installed on the upper back side of the feeding hopper 4. A transmission rod 17 is rotatably installed inside the fixed plate 16. A bevel gear 18 is fixedly installed at the end of the transmission rod 17 and the drive screw 7, and the two bevel gears 18 are configured to cooperate. A protective cover 22 is fixedly installed on the top of the mounting plate 5. The protective cover 22 covers the outside of the bevel gears 18. The transmission rod 17 is rotatably installed on the side of the protective cover 22. Synchronous pulleys 19 are fixedly sleeved on the rod walls of the transmission rod 17 and the rotating rod 13. A synchronous belt 20 is configured to drive between the two synchronous pulleys 19.

[0021] Working principle: When conveying raw materials, the raw materials are first put into the feeding hopper 4, and then the reciprocating motor 12 is started. Its output shaft drives the rotating rod 13 to rotate. The rotating rod 13 drives the transmission rod 17 to rotate through the synchronous pulley 19 and the synchronous belt 20. The bevel gear 18 at the end of the transmission rod 17 meshes with the bevel gear 18 at the end of the drive screw 7, thereby causing the drive screw 7 to rotate. When the drive screw 7 rotates, the slider 8, which is threaded onto its wall, slides on the support frame 6. The slider 8 drives the push plate 10 to move through the support rod 9. Since the top of the push plate 10 is in contact with the limiting plate 11, the limiting plate 11 restricts the rotation direction of the push plate 10, so that the push plate 10 squeezes and pushes the jute raw material in the feeding hopper 4 during the movement, and pushes the raw material into the guide box 1 through the guide pipe 3. At the same time, the rotating rod 13 drives the feeding plate 14 to rotate. The receiving groove 15 on the outer wall of the feeding plate 14 intermittently receives the raw material in the guide box 1. When the receiving groove 15 rotates to the discharge port at the bottom of the guide box 1, the raw material is discharged from the discharge port, realizing intermittent feeding and minimizing the accumulation of raw material inside the combing machine, thus increasing the burden on the combing machine. In addition, the corrugated protective tube 21 can prevent dust and other particles from entering the mating part of the drive screw 7 and the slider 8, while the protective cover 22 protects the bevel gear 18.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
