AI Technical Summary
The existing cotton grabbing machine's leveling spool has only one flat laying direction, resulting in inconsistent fiber flatness on the cotton bale. This makes it difficult to control the transverse and longitudinal thickness and density of the cotton layer, and it cannot adapt to cotton piles of different heights, affecting yarn quality and cotton grabbing efficiency.
A reciprocating cotton grabber with a leveling function was designed. It uses two leveling wheels to process cotton from different directions and automatically adjusts the grabbing depth to adapt to different cotton heights by sensing the cotton height through a proximity sensor.
This achieves uniform leveling of the cotton layer in both the horizontal and vertical directions, improving yarn quality and cotton-grabbing efficiency, and ensuring the continuity and stability of subsequent production processes.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton processing technology, specifically a reciprocating cotton grabber with a leveling function. Background Technology
[0002] Cotton generally refers to plants of the genus Gossypium in the Malvaceae family, such as upland cotton, herbaceous cotton, and tree cotton. They are annual herbaceous or subshrub plants with sparsely covered long soft hairs on their twigs. Their seeds are separate, oval, and have long white cottony hairs and short grayish-white cottony hairs that are not easily detached.
[0003] A cotton grabber, also known as a bale grabber, is a machine in a cotton opening and cleaning unit that grabs cotton fibers from cotton bales. It is usually located at the beginning of the unit and comes in various types, including top grabber, bottom grabber, trolley reciprocating type, trolley or cotton bale table rotary type, trolley lifting type, and platform lifting type.
[0004] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. The leveling spool on the cotton grabber only has one direction for adjusting the flatness, which results in a relatively uniform flatness position of the fibers on the cotton bale. During production, different cotton bales have different fiber characteristics. When a leveling machine with only one direction is working, it can only process the cotton layer in one direction. In the direction perpendicular to this direction, it is difficult to effectively control the thickness and density of the cotton layer. For example, in textile production, after the cotton undergoes initial opening, it enters the leveling stage. If the leveling machine is unidirectional, it's like using a comb to only comb hair in one direction, resulting in inconsistent flatness of the cotton layer in the horizontal and vertical directions. This can lead to uneven cotton layers received by the machine in subsequent processes such as carding and drawing, thus affecting yarn quality and causing uneven yarn thickness. 2. When the cotton height varies, the cotton grabber cannot adapt to cotton of different heights, resulting in inappropriate grabbing depth. If the cotton is piled high and the grabbing depth of the cotton grabber is fixed, the amount of cotton grabbed each time will be insufficient. For example, in the raw material warehouse of a cotton mill, the stacking height of cotton bales may vary due to factors such as batch and packaging method. If the cotton grabber cannot adjust the grabbing depth according to the actual cotton height, more grabbing attempts are required to obtain the same amount of cotton, which will reduce the overall efficiency of cotton grabbing and affect the continuity of subsequent production processes. Utility Model Content
[0005] The purpose of this utility model is to provide a reciprocating cotton grabber with a leveling function to solve the problem mentioned in the background art where the cotton pile is high, but the grabbing depth of the cotton grabber is fixed, resulting in insufficient cotton being grabbed each time. To achieve the above objective, this utility model provides the following technical solution: a reciprocating cotton grabber with a leveling function, including a cotton storage box, with a housing provided above the cotton storage box;
[0006] The inner wall of the cotton storage box is welded with a first slide rail and a second slide rail. The second slide rail is provided on one side of the first slide rail. A slide rod is installed inside the first slide rail by screws. A first threaded screw is rotatably connected inside the second slide rail. A first motor is rotatably connected to one side of the first threaded screw. A slider is attached to the outer wall of the slide rod. A fixing plate is installed above the slider by screws. The housing of a cylinder is installed inside the fixing plate by screws.
[0007] A first pulley and a second pulley are screwed onto one side of the equipment housing. The first pulley and the second pulley are connected by a first drive belt, and the second pulley and the third pulley are connected by a second drive belt. A proximity sensor is screwed into the inside of the equipment housing. A shaft on one side of the first pulley is inserted into a second threaded screw. A connecting plate is threaded onto the outer wall of the second threaded screw. A first leveling wheel is rotatably connected inside the connecting plate. A spur gear is inserted into the front shaft of the first leveling wheel. A rack meshes with the spur gear above it. A shaft on one side of the second pulley is inserted into the second leveling wheel. A cotton-grabbing rod is inserted into one side of the third pulley. A cotton-grabbing blade is screwed onto the outer wall of the cotton-grabbing rod.
[0008] More preferably, the inner wall of the cotton storage box is horizontally equipped with a first slide rail and a second slide rail, and two sliders are respectively installed below the fixing plate. The internal structural dimensions of the slider are consistent with the external structural dimensions of the slide rod, and the internal thread of the other slider is consistent with the external thread structural dimensions of the first threaded rod.
[0009] In a further preferred embodiment, the first threaded screw forms a rotating structure via the first motor, and the slider forms a horizontal sliding structure via the first threaded screw and the slide rod, and the fixed plate forms a sliding structure via the slider.
[0010] More preferably, the other side of the cotton-grabbing rod is connected to the output shaft of the drive motor, the housing of the drive motor is mounted with a device housing by screws, and the cotton-grabbing rod forms a rotating structure through the drive motor, with several cotton-grabbing blades horizontally mounted on the outer wall of the cotton-grabbing rod.
[0011] More preferably, the third pulley has two limiting grooves inside, and the first limiting groove is connected to the first limiting groove of the second pulley through a second drive belt. The second pulley has two limiting grooves inside, and the second limiting groove of the second pulley is connected to the first limiting groove of the first pulley through a first drive belt. The other side of the third pulley has another set of the same first pulley, first drive belt, second pulley and second drive belt.
[0012] More preferably, the second leveling wheel forms a rotating structure via a second pulley.
[0013] More preferably, the second threaded screw forms a rotating structure through the first pulley, and the internal thread on the upper part of the connecting plate is consistent with the external structural dimensions of the second threaded screw, and the first flattening wheel forms a rotating structure through a spur gear.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In this invention, the first and second leveling wheels simultaneously flatten the cotton in the cotton storage box. The two leveling wheels are powered by different interconnected structures and rotate, enabling them to process the cotton in multiple directions, much like combing hair with both hands at the same time. This allows the cotton layer to be effectively leveled both horizontally and vertically. As a result, in the subsequent cotton-grabbing process, the cotton-grabbing blades can pick up a more uniform cotton layer, and the quality of the cotton layer supplied to subsequent carding, drawing, and other processes is more stable. This helps to reduce uneven yarn thickness and improve product quality.
[0016] In this invention, a proximity sensor detects the height of the cotton and sends feedback to the control cabinet, which then controls the vertical movement of the equipment housing. This allows the gripping depth to be adjusted according to the actual height of the cotton. When the cotton is piled high, the equipment housing can be lowered to ensure that enough cotton is gripped each time, reducing the number of gripping operations. Compared to the previous situation where it was impossible to adapt to different cotton heights, this greatly improves the overall efficiency of gripping cotton and ensures the continuity of subsequent production processes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a reciprocating cotton grabber with a leveling function, including a cotton storage box 1, and an equipment shell 2 above the cotton storage box 1;
[0024] The inner wall of the cotton storage box 1 is welded with a first slide rail 101 and a second slide rail 107. The second slide rail 107 is provided on one side of the first slide rail 101. A slide rod 108 is installed inside the first slide rail 101 by screws. A first threaded screw 106 is rotatably connected inside the second slide rail 107. A first motor 105 is rotatably connected on one side of the first threaded screw 106. A slider 102 is attached to the outer wall of the slide rod 108. A fixing plate 103 is installed above the slider 102 by screws. The housing of the cylinder 104 is installed inside the fixing plate 103 by screws.
[0025] A first pulley 202 and a second pulley 203 are screwed onto one side of the equipment housing 2. The first pulley 202 and the second pulley 203 are connected by a first drive belt 213, and the second pulley 203 and the third pulley 204 are connected by a second drive belt 214. A proximity sensor 201 is screwed onto the inside of the equipment housing 2. A shaft on one side of the first pulley 202 is inserted into a second threaded screw 206. A connecting plate 209 is threaded onto the outer wall of the second threaded screw 206. A first leveling wheel 208 is rotatably connected inside the connecting plate 209. A shaft in front of the first leveling wheel 208 is inserted into a spur gear 207. A rack 205 meshes with the top of the spur gear 207. A shaft on one side of the second pulley 203 is inserted into a second leveling wheel 211. A cotton-grabbing rod 210 is inserted onto one side of the third pulley 204. A cotton-grabbing blade 212 is screwed onto the outer wall of the cotton-grabbing rod 210.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a first slide rail 101 and a second slide rail 107 are horizontally installed on both sides of the inner wall of the cotton storage box 1, and two sliders 102 are respectively installed below the fixed plate 103. The internal structural dimensions of the slider 102 are consistent with the external structural dimensions of the slide rod 108, and the internal thread of the other slider 102 is consistent with the external thread structural dimensions of the first threaded screw 106. The fixed plate 103 is stable during movement to avoid shaking or displacement. At the same time, through the cooperation of the slide rod 108 and the first threaded screw 106, the movement of the fixed plate 103 is more precise, and the position can be adjusted according to actual needs to improve the efficiency and accuracy of cotton grabbing.
[0027] In this embodiment, as Figure 3 As shown, the first threaded screw 106 forms a rotating structure through the first motor 105, and the slider 102 forms a horizontal sliding structure through the first threaded screw 106 and the slide bar 108, and the fixed plate 103 forms a sliding structure through the slider 102; the position of the fixed plate 103 is precisely adjusted by controlling the speed and direction of the first motor 105. At the same time, the horizontal sliding structure makes the cotton grabbing process more flexible, and cotton can be grabbed at different positions, improving the adaptability of the equipment.
[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the output shaft of the drive motor is connected to the other side of the cotton-grabbing rod 210. The housing of the drive motor is mounted on the equipment housing 2 by screws, and the cotton-grabbing rod 210 forms a rotating structure through the drive motor. Several cotton-grabbing blades 212 are horizontally mounted on the outer wall of the cotton-grabbing rod 210. The output shaft of the drive motor is connected to the other side of the cotton-grabbing rod 210. The drive motor drives the cotton-grabbing rod 210 to rotate. During the rotation, the several cotton-grabbing blades 212 on the outer wall of the cotton-grabbing rod 210 grab cotton. The drive motor provides strong power to the cotton-grabbing rod 210, enabling the cotton-grabbing blades 212 to grab cotton quickly and effectively. The design of multiple cotton-grabbing blades 212 increases the area and efficiency of cotton grabbing, and improves the working performance of the equipment.
[0029] In this embodiment, as Figure 4As shown, the third pulley 204 has two limiting grooves inside, and the first limiting groove is connected to the first limiting groove of the second pulley 203 through the second drive belt 214. The second pulley 203 has two limiting grooves inside, and the second limiting groove of the second pulley 203 is connected to the first limiting groove of the first pulley 202 through the first drive belt 213. On the other side of the third pulley 204, there is another set of the same first pulley 202, first drive belt 213, second pulley 203 and second drive belt 214. The transmission between multiple pulleys, this transmission structure, enables the various components to work together to provide power for the rotation of the first leveling wheel 208 and the second leveling wheel 211. The transmission and distribution of power make the structure of the equipment more compact and reduce the space occupation.
[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the second leveling wheel 211 forms a rotating structure through the second belt pulley 203. During the cotton grabbing process, the second leveling wheel 211 rotates to flatten the cotton, making the cotton more evenly distributed in the cotton storage box 1, which facilitates the cotton grabbing blade 212 to grab the cotton. The rotational flattening effect of the second leveling wheel 211 improves the flatness of the cotton, making the cotton grabbing more even, reducing the accumulation and omission of cotton, and improving the quality and efficiency of cotton grabbing.
[0031] In this embodiment, as Figure 4 As shown, the second threaded screw 206 forms a rotating structure through the first pulley 202, and the internal thread on the upper part of the connecting plate 209 is consistent with the external structural dimensions of the second threaded screw 206. The first leveling wheel 208 forms a rotating structure through the spur gear 207. This allows the connecting plate 209 to move under the rotation of the second threaded screw 206. The first leveling wheel 208 forms a rotating structure through the spur gear 207, and flattens the cotton during the movement. The automatic movement and rotational leveling function of the first leveling wheel 208 works in conjunction with the second leveling wheel 211 to further improve the flatness of the cotton. At the same time, through the threaded connection and gear transmission, the operation of the equipment is more stable and reliable, and the service life of the equipment is improved.
[0032] The usage and advantages of this utility model: The reciprocating cotton grabber with leveling function operates as follows:
[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, cotton is first placed into the cotton storage box 1. A proximity sensor 201 located below the equipment housing 2 approaches the cotton, providing feedback to an external control cabinet. The control cabinet then controls cylinder 104, causing the equipment housing 2 to move vertically downwards. A drive motor on the other side of the equipment housing 2 rotates the cotton-grabbing rod 210. The outer wall of the cotton-grabbing rod 210 uses cotton-grabbing blades 212 to grab the cotton. A third pulley 204 on one side of the cotton-grabbing rod 210 is connected to the second pulley 203 via a second drive belt 214, causing the second pulley 203 to drive the second leveling wheel 211 to rotate. The second pulley 203 and the first pulley 202 are connected via a first drive belt 213, which in turn causes the second threaded screw 206 to rotate. The internal thread structure of the screw 206 is consistent with that of the connecting plate 209. When the first leveling wheel 208 inside the connecting plate 209 rotates, the spur gear 207 meshes with the rack 205, so that the spur gear 207 drives the first leveling wheel 208 to rotate. The first leveling wheel 208 and the second leveling wheel 211 simultaneously flatten the cotton in the cotton storage box 1, making it easier for the cotton grabbing blade 212 to grab the cotton. The first motor 105 rotates the first screw 106 clockwise in sequence. The external structural dimensions of the first screw 106 are consistent with the thread dimensions of the slider 102, so that the fixed plate 103 can move horizontally through the slider 102. The other slider 102 provides support on the slide rod 108, making it easy to adjust the movement of the fixed plate 103 to grab cotton.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
