Description

Technical Field

[0001] The utility model relates to the technical field of cotton yarn production, and specifically relates to a carding machine for cotton yarn production. Background Art

[0002] After searching, the patent with publication number CN212955482U discloses a high-efficiency carding machine for cotton yarn production. When the raw material is blocked in the feed hopper, the device extends the telescopic rod to the right end by rotating the threaded ring, so that the first active bevel gear and the first driven bevel gear are meshed and transmitted, driving the telescopic rod to rotate, thereby driving the rotating shaft to rotate through the meshing transmission between the second active bevel gear and the second driven bevel gear, and then the half gear is rotated, and the half gear is meshed and transmitted with the rack, so that the rack moves downward, driving the pressure plate to press the raw material in the feed hopper. Since there is a notch on the half gear, when the half gear is in the notch, the rack is restored to its initial state through the spring, thereby achieving the immobility of the pressure plate.

[0003] The above equipment can mechanically replace manual labor to achieve the pressing of raw materials in the feed hopper. However, the cotton wool itself is light and easy to float. When the pressing plate moves down, the side of the pressing plate does not have a good closing design. The light cotton wool will enter the area above the pressing plate through the gap between the side of the pressing plate and the feed hopper. When the pressing plate moves up, there is a problem of raw materials being brought out of the feed hopper. Therefore, a cotton carding machine for cotton yarn production is needed.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A carding machine for cotton yarn production refers to a piece of equipment used in the textile industry to process cotton or other fibers into a combed state suitable for spinning. The main function of a carding machine is to comb and clean raw cotton or blended fibers to remove impurities, coarse fibers and short fibers, and to make the fibers more uniform in length. This equipment plays a key role in the textile industry, affecting the quality and efficiency of subsequent spinning and weaving processes.

[0025] Existing equipment can mechanically replace manual labor to achieve the pressing of raw materials in the feed hopper. However, cotton wool itself is light and easy to float. When the pressing plate moves down, the side of the pressing plate is not well closed. The light cotton wool will enter the area above the pressing plate through the gap between the side of the pressing plate and the feed hopper. When the pressing plate moves up, there is a problem that the raw materials are taken out of the feed hopper. Figure 1-Figure 5 The embodiment provides a carding machine for cotton yarn production, including a carding machine 1 and a feed hopper 2 fixed on the top of the carding machine 1, and an n-shaped frame 3 is fixedly connected to the top of the carding machine 1.

[0026] refer to Figure 2-Figure 4As shown, the existing equipment can mechanically replace manual labor to achieve the pressing of the raw materials in the feed hopper 2. However, the cotton wool itself is light and easy to float. When the pressing plate moves down, the side of the pressing plate 42 does not have a good sealing design. The light cotton wool will enter the area above the pressing plate 42 through the gap between the side of the pressing plate 42 and the feed hopper 2. When the pressing plate 42 moves up, there is a problem that the raw materials are taken out of the feed hopper 2. In order to ensure that the feed hopper 2 can be unblocked smoothly when blocked, the following settings are made: the inner top wall of the n-shaped frame 3 is provided with a pressing mechanism 4 for pressing and unblocking the raw materials in the feed hopper 2. The pressing mechanism 4 includes two anti-overflow plates 43. The inner wall of the pressing plate 42 is fixedly connected with a buffer pad 5. The material of the impact pad 5 is rubber material, the top of the buffer pad 5 is flush with the inner bottom wall of the mounting groove 441, and the top of the buffer pad 5 is in contact with the bottom of the anti-overflow plate 43. When the pressure plate 42 is reset, the anti-overflow plates 43 on both sides are not blocked by the inner wall of the feed hopper 2 and will be reset through the torsion spring 443. After the reset, the anti-overflow plates 43 are flush with the top of the buffer pad 5. The buffer pad 5 plays a role in protecting the anti-overflow plates 43 and can prevent the anti-overflow plates 43 from directly contacting the hard surface of the mounting groove 441 during movement, thereby reducing wear and damage. The buffer pad 5 can also provide a certain buffering effect when the anti-overflow plates 43 are reset, reduce the impact force, and help to extend the service life and stability of the anti-overflow plates 43. The inner top wall of the n-shaped frame 3 is fixedly connected with a cylinder 41, and the telescopic end of the cylinder 41 is fixedly connected with a pressure plate 42. The pressure plate 42 is arranged between two anti-overflow plates 43. Two power components 44 are symmetrically arranged on both sides of the pressure plate 42 for making the two anti-overflow plates 43 relatively rotate upward according to the shape of the inner cavity of the feed hopper 2 when the two anti-overflow plates 43 move downward. The power component 44 includes a mounting groove 441 opened on the top of the pressure plate 42, and the interior of the mounting groove 441 is rotatably connected with a rotating rod 442. The anti-overflow plate 43 is fixed to the outer wall of the rotating rod 442. Two torsion springs 443 are symmetrically arranged at both ends of the rotating rod 442. The two ends of the two torsion springs 443 are evenly divided. They are fixedly connected to the mounting groove 441 and the rotating rod 442, and the outsides of the two torsion springs 443 are each sleeved with a protective tube 4431. The two ends of the protective tube 4431 rotate between the mounting groove 441 and the anti-overflow plate 43. The protective tube 4431 is used to place the torsion spring 443 in a sealed environment for use. The sealed environment can effectively prevent moisture, chemicals or other pollutants in the air from entering the torsion spring 443. The sealed environment can usually provide more stable working conditions and avoid the impact of sudden environmental changes or external factors on the torsion spring 443, which helps the torsion spring to operate stably under the expected working parameters.When the raw materials are blocked in the feed hopper 2, the cylinder 41 is started to drive the telescopic end to move the pressure plate 42 downward and place it in the feed hopper 2. The anti-overflow plates 43 on both sides of the pressure plate 42 will move downward with the pressure plate 42 and be pushed by the inner wall of the feed hopper 2 so as to rotate upward relatively. The relative upward rotation of the anti-overflow plates 43 will drive the rotating rod 442 to rotate. The rotation of the rotating rod 442 will twist the torsion spring 443, forming a top block for the raw materials in the feed hopper 2 while fully clearing the raw materials in the feed hopper 2, preventing the cleared raw materials from entering the area above the pressure plate 42 from the gap between the pressure plate 42 and the feed hopper 2, and preventing the raw materials from being brought out of the feed hopper 2 when the pressure plate 42 moves upward, ensuring that the feed hopper 2 can be cleared smoothly when blocked.

[0027] refer to Figure 4-Figure 5 As shown, during the cotton yarn processing, cotton wool often moves through mechanical movement or air flow. When the cotton wool contacts the surface of the mechanical equipment, especially the pressing plate 42, if the contact or separation speed between the cotton wool and the pressing plate 42 is appropriate and the air humidity is low, static electricity will be generated between the pressing plate 42 and the cotton wool, which will cause the cotton wool to adhere to the surface or below the pressing plate 42, affecting the efficiency of the production process and the quality of the product. In order to reduce the generation of static electricity at the bottom of the pressing plate 42, the following settings are made: the bottom of the pressing plate 42 is fixedly connected to an anti-static plate 6 to reduce the static electricity at the bottom of the pressing plate 42. In order to prevent the generation of static electricity and the adhesion of cotton wool, the antistatic plate 6 is composed of a conductive rubber base pad 61 and an antistatic coating 62. The antistatic coating 62 is fixedly connected to the bottom of the conductive rubber base pad 61. The antistatic coating 62 and the conductive rubber base pad 61 can be used together to significantly reduce the problem of static electricity accumulation. The conductive layer formed on the surface of the antistatic coating 62 and the good grounding connection between the conductive rubber base pad 61 work together to control and release static electricity, thereby avoiding the accumulation of a large amount of static electricity on the surface of the pressing plate 42, thereby reducing the static electricity contact between the cotton wool and the pressing plate 42.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
