[0002] Carding machines play a crucial role in the textile production process. Their main function is to open, remove impurities, and comb the cotton after it has been opened and cleaned, so that it becomes a single fiber and is made into a uniform sliver for use in the subsequent spinning process. The feed plate, as an important component of the carding machine, works in conjunction with the feed rollers to stably transport the cotton to the licker-in rollers for combing. CN205171044U discloses a "feeding plate for optimizing the carding process of a carding machine, including an upper plate, a middle plate and a bottom plate, wherein one side of the upper surface of the upper plate is a plane...the threaded end of the fastening screw contacts the bottom plate". The feeding plate of this utility model can adjust the gap between the arc surface and the roller according to different spun raw materials, so that it has the best gripping force on the cotton layer, achieving the best carding effect and carding efficiency, and the gap between the arc surface and the roller is easy to adjust. In the aforementioned patent, the adjustment method of the cotton feeder is rather cumbersome, requiring manual or tool-assisted turning of multiple adjusting screws and fastening screws to adjust the position of the cotton feeder. This operation is time-consuming and labor-intensive, and also results in long downtime, affecting the working efficiency of the carding machine. Therefore, a cotton feeder for a carding machine in textiles is proposed to solve the above problems. Utility Model Content

[0013] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0014] This application discloses a cotton feeding plate for a carding machine used in textiles. (Refer to...) Figure 1-4 A cotton feeding plate for a textile carding machine includes a bottom plate 1, a middle plate 2, a cotton feeding plate 3, and a cotton feeding roller 4. The bottom plate 1 serves as the basic support structure of the entire cotton feeding plate device. Its material is usually high-strength alloy steel, which has good rigidity and stability and can withstand various forces generated during the operation of the entire device. The bottom plate 1 is fixedly connected to the frame of the carding machine by bolts to ensure a firm installation.

[0015] The middle layer plate 2 is installed above the bottom layer plate 1 through a displacement adjustment assembly. The displacement adjustment assembly enables the middle layer plate 2 to move precisely in the horizontal direction, thereby adjusting the horizontal distance between the cotton feeding plate 3 and the cotton feeding roller 4. The cotton feeding plate 3 is hinged to the top outer wall of the middle layer plate 2 through a connecting seat 21. The connecting seat 21 is made of high-strength metal and is fixed to the middle layer plate 2 by welding. The cotton feeding plate 3 and the connecting seat 21 are connected by a pin, so that the cotton feeding plate 3 can rotate around the pin.

[0016] An angle adjustment mechanism is installed between the middle plate 2 and the feed plate 3. This mechanism can adjust the tilt angle of the feed plate 3 to adapt to textile raw materials with different characteristics. The outer wall of the feed plate 3 is provided with an arc-shaped surface 5. The arc-shaped surface 5 is processed by a special process, and its surface is smooth and has a certain curvature, which can perfectly match the outer circumference of the feed roller 4. The feed roller 4 is located directly above the arc-shaped surface 5 on the outer wall of the feed plate 3. Its outer circumference matches the arc-shaped surface 5, and a gradually narrowing gap is formed between the two. This gap is the key channel for the cotton to enter the carding area. The feed roller 4 is mounted on the frame of the carding machine through bearing seats at both ends.

[0017] The angle adjustment mechanism includes a slide cylinder 6 and a screw 7. A fixing plate 11 is welded to the outer wall of the two slide cylinders 6. The slide cylinder 6 adopts a cylindrical hollow structure with a smooth interior, which can guide the movement of the screw 7. The fixing plate 11 serves as a connection and support. A worm gear 12 is rotatably connected to its top outer wall. The worm gear 12 is connected to the fixing plate 11 through a rolling bearing, which can reduce the friction during rotation. The top ends of the two slide cylinders 6 are rotatably connected to a worm wheel 9 through a bearing ring 8. The worm wheel 9 meshes with the worm gear 12 to form a worm gear transmission mechanism. The worm wheel 9 is threaded to the outer wall of the screw 7. The rotation of the worm wheel 9 can drive the screw 7 to move axially.

[0018] In practical applications, for textile raw materials of different thicknesses, the position of the middle plate 2 and the angle of the feed plate 3 can be adjusted to achieve the optimal gap and angle between the feed plate 3 and the feed roller 4, ensuring that the raw materials can smoothly enter the carding area and improve the carding effect. For example, when processing thicker raw materials, the distance between the middle plate 2 and the bottom plate 1 can be appropriately increased, and the angle of the feed plate 3 can be adjusted to allow the raw materials to pass through more smoothly.

[0019] The screw 7 is located inside the slide cylinder 6, and its bottom end is slidably connected to the inner wall of the slide cylinder 6 through the limiting slider 10. Specifically, the limiting slider 10 and the slide cylinder 6 are connected by a key, which can prevent the screw 7 from rotating during movement and ensure that the screw 7 can slide freely inside the slide cylinder 6. The top end of the screw 7 passes through the bearing ring 8 and the worm gear 9 in sequence and is hinged to the bottom outer wall of the cotton feeding plate 3. This connection method allows the lifting and lowering of the screw 7 to drive the cotton feeding plate 3 to rotate around the connecting seat 21, thereby realizing the adjustment of the angle of the cotton feeding plate 3. The bottom outer wall of the slide cylinder 6 is hinged to the top outer wall of the middle layer plate 2. The hinge uses a wear-resistant spherical bearing, which can ensure that the slide cylinder 6 is flexible and stable during rotation.

[0020] In actual operation, when it is necessary to adjust the angle of the feed plate 3, the operator turns the handle 13, which drives the worm gear 12 to rotate. The worm gear 12 drives the worm wheel 9 to rotate, and the worm wheel 9 causes the screw 7 to move axially through the threaded transmission. Since the top of the screw 7 is hinged to the bottom of the feed plate 3, as the screw 7 rises and falls, the feed plate 3 rotates around the connecting seat 21, so as to achieve precise angle adjustment. For example, when processing textile raw materials with long fibers, the tilt angle of the feed plate 3 can be increased by adjusting the angle adjustment mechanism, so as to better guide the raw materials into the combing area and avoid fiber entanglement.

[0021] The displacement adjustment assembly includes a lead screw 15 and a screw block 18. A straight groove 14 is provided on the top outer wall of the bottom plate 1. The length direction of the straight groove 14 is consistent with the axial direction of the lead screw 15. The lead screw 15 is rotatably connected to the inner walls of both ends of the straight groove 14. The two ends of the lead screw 15 are connected to the inner walls of the straight groove 14 through rolling bearings to ensure that the lead screw 15 can rotate smoothly. A servo motor 17 is fixedly mounted on one end of the lead screw 15 through a mounting bracket 16. The mounting bracket 16 is made of metal and is fixedly connected to the bottom plate 1 by bolts. The output shaft end of the servo motor 17 passes through the straight groove 14 and is fixedly connected to one end of the lead screw 15. The servo motor 17 can precisely control the rotation angle and speed of the lead screw 15.

[0022] A screw block 18 is welded to the bottom outer wall of the middle layer plate 2. The screw block 18 is threadedly connected to the lead screw 15. The internal thread of the screw block 18 matches the external thread of the lead screw 15, which can realize stable thread transmission. At the same time, the dovetail block 19 at the bottom of the middle layer plate 2 is in sliding engagement with the dovetail groove 20 at the top of the bottom layer plate 1. The engagement of the dovetail block 19 and the dovetail groove 20 can restrict the movement direction of the middle layer plate 2, so that it can only move along the axial direction of the lead screw 15, ensuring the accuracy and stability of displacement adjustment.

[0023] In actual production, different batches of textile raw materials may have different characteristics, such as fiber thickness and elasticity. Through the displacement adjustment component, the operator can adjust the position of the middle plate 2 by controlling the servo motor 17 according to the specific conditions of the raw materials, thereby changing the horizontal distance between the feed plate 3 and the feed roller 4. For example, for finer fiber raw materials, the distance can be appropriately reduced to enhance the gripping force on the raw materials; for coarser fiber raw materials, the distance can be increased to prevent the raw materials from being damaged by excessive compression during the conveying process.

[0024] A servo motor 17 is fixedly mounted on the outer wall of the middle section of one side of the bottom plate 1 via a mounting bracket 16. The design of the mounting bracket 16 fully considers the installation size and working requirements of the servo motor 17, and can provide stable support for the servo motor 17. The end of the output shaft of the servo motor 17 passes through the straight groove 14 and is fixedly connected to one end of the lead screw 15. The connection method adopts a key connection to ensure reliable power transmission. The servo motor 17 has high-precision position control and speed control functions. Through the matching control system, the operator can accurately set the number of rotations and direction of the lead screw 15, thereby realizing the precise displacement of the middle plate 2.

[0025] In practical applications, when it is necessary to adjust the horizontal distance between the feed plate 3 and the feed roller 4, the operator sends a command to the servo motor 17 through the control system. The servo motor 17 drives the lead screw 15 to rotate according to the command. When the lead screw 15 rotates, it drives the middle layer plate 2 to move along the axial direction of the lead screw 15 through the threaded transmission with the screw block 18. Due to the high-precision control of the servo motor 17, the displacement of the middle layer plate 2 can be controlled within a very precise range to meet the requirements of different textile raw materials for the distance between the feed plate 3 and the feed roller 4. For example, in the production of high-grade textiles, the requirements for the combing of raw materials are high. By precisely adjusting the distance through the servo motor 17, it can be ensured that the raw materials are better processed during the combing process and the product quality is improved.

[0026] Two dovetail grooves 20 are formed on the top outer wall of the bottom plate 1. The length direction of the dovetail grooves 20 is consistent with the axis of the lead screw 15, and the two dovetail grooves 20 are arranged in parallel. The dovetail grooves 20 have high machining accuracy, which can ensure good fit with the dovetail blocks 19. Two dovetail blocks 19 are fixedly connected to the bottom outer wall of the middle plate 2. The shape of the dovetail blocks 19 is adapted to the dovetail grooves 20. The two adopt a clearance fit, which can not only ensure that the dovetail blocks 19 can slide freely in the dovetail grooves 20, but also provide a certain guiding and limiting function.

[0027] The cooperation between the dovetail block 19 and the dovetail groove 20 plays an important role in the displacement adjustment process. When the lead screw 15 rotates and drives the middle plate 2 to move, the dovetail block 19 slides in the dovetail groove 20, which restricts the movement direction of the middle plate 2, so that it can only move along the axial direction of the lead screw 15. This prevents the middle plate 2 from shifting or shaking during the movement, ensuring the stability and accuracy of the displacement adjustment. At the same time, this structure can also withstand a certain lateral force, which enhances the reliability of the entire displacement adjustment component. For example, during the operation of the carding machine, it may be subjected to some vibration and impact. The cooperation between the dovetail block 19 and the dovetail groove 20 can effectively resist these external forces and ensure that the relative position between the feed plate 3 and the feed roller 4 remains stable.

[0028] A handle 13 is fixedly connected to one end of the worm gear 12. The handle 13 is ergonomically designed with a non-slip surface for easy gripping by the operator. The handle 13 and the worm gear 12 are fixed together by welding or keying to ensure that the rotation of the handle 13 can be reliably transmitted to the worm gear 12.

[0029] In actual operation, when it is necessary to adjust the tilt angle of the cotton feed plate 3, the operator holds the handle 13 and rotates it. The handle 13 drives the worm 12 to rotate, and the worm 12 meshes with the worm wheel 9. The rotation of the worm 12 drives the worm wheel 9 to rotate. Since the worm wheel 9 is threadedly connected to the outer wall of the screw 7, the rotation of the worm wheel 9 causes the screw 7 to move axially through the threaded transmission. The top of the screw 7 is hinged to the bottom outer wall of the cotton feed plate 3. As the screw 7 rises and falls, the cotton feed plate 3 rotates around the connecting seat 21, thereby adjusting the tilt angle. The operator can continuously adjust the rotation angle of the handle 13 by observing the conveying status of the raw materials and the combing effect during the cotton feeding process until the cotton feed plate 3 reaches the optimal working angle. For example, when processing different varieties of cotton, since the fiber length and elasticity of cotton are different, adjusting the angle of the cotton feed plate 3 by rotating the handle 13 can make the cotton better processed during the combing process, improving the working efficiency and product quality of the carding machine.
