Description

Technical Field

[0001] This utility model relates to the field of cotton grabbing machine technology, and in particular to an automatic cotton grabbing machine. Background Technology

[0002] The cotton grabber is a key piece of equipment in the opening and cleaning process of textile manufacturing. It is mainly used to grab, open, and mix fiber raw materials, and remove impurities. As the first step in the opening and cleaning unit, the cotton grabber is suitable for clothing factories, textile mills, and hygiene product factories. Its technological development trend is towards shorter processes and higher efficiency, focusing on improving the uniformity of cotton mixing and reducing fiber damage. Common types include disc-type cotton grabbers, available in various specifications to meet different production needs.

[0003] For example, Chinese utility model patent (CN217809813U) discloses a reciprocating cotton grabber, including a base plate and a control box. Electric slide rails are provided on both sides of the base plate, and a rotary tower is slidably installed inside the electric slide rails. A cotton grabbing mechanism is connected to the center of the rotary tower. A connecting frame is provided in the center of the base plate, and a conveyor belt is installed in the center of the connecting frame. An auxiliary plate is provided on the outer surface of the connecting frame, and a connecting plate is installed on the outer surface of the auxiliary plate. This reciprocating cotton grabber, by rotating the threaded rod in the center of the connecting plate counterclockwise or clockwise, allows the cleaning soft brush, which is rotatably connected to the threaded rod, to move up and down. When cleaning is required, the auxiliary plate causes one side of the cleaning brush to flip closer to the cleaning soft brush. Thus, the movement of the electric slide rails and the rotary tower synchronously moves the cleaning brush, allowing it to effectively clean the cleaning fibers.

[0004] However, when the inventors implemented this device, they found the following defects: the cotton grabber lacks a cleaning mechanism for the working area. Cotton lint that falls during the grabbing process tends to accumulate on the surface of the sliding table and the transmission parts of the equipment, increasing the risk of equipment failure. It also requires frequent shutdowns for cleaning, reducing production continuity and equipment lifespan. Utility Model Content

[0005] Based on this, it is necessary to address the aforementioned technical issues. The cotton grabber lacks a cleaning mechanism for the working area. During the cotton grabbing process, the cotton lint that falls off easily accumulates on the surface of the sliding table and at the transmission parts of the equipment, increasing the risk of equipment failure. It also requires frequent shutdowns for cleaning, reducing production continuity and equipment lifespan.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic cotton grabbing machine includes a cotton grabbing mechanism, a sliding base fixedly installed below the cotton grabbing mechanism, a sliding platform provided below the sliding base, a groove formed at the middle of the bottom of the sliding base, the sliding base slidingly engaging with the sliding platform through the groove, cleaning mechanisms provided at both ends of the bottom of the sliding base near the raw material, and a material receiving mechanism provided at the end of the sliding base near the raw material, the material receiving mechanism being located between the two cleaning mechanisms.

[0007] In a preferred embodiment of the automatic cotton grabber provided by this utility model, the bottom of the sliding base is provided with protruding plates at both ends, and the protruding plates are slidably located on the top of the sliding table.

[0008] In a preferred embodiment of the automatic cotton grabber provided by this utility model, the cleaning mechanism includes a cleaning disc, which is close to the ground. A central shaft is fixedly provided at the center of the cleaning disc, and the top of the central shaft is rotatably connected to the protruding plate.

[0009] In a preferred embodiment of the automatic cotton grabber provided by this utility model, a first gear is fixedly arranged on the surface of the central shaft near the top, a groove is opened on the surface of the sliding table near the raw material, a rack is arranged on the inner wall of the groove, a second gear is arranged between the first gear and the groove, the middle part of the second gear is connected to the protrusion through a rotating shaft, and the surface of the second gear meshes with the rack and the first gear respectively.

[0010] In a preferred embodiment of the automatic cotton grabber provided by this utility model, the receiving mechanism includes two receiving plates. A vertical plate is fixedly installed on the sliding base near the middle of the raw material. The two receiving plates are respectively installed at both ends of the vertical plate. A baffle is fixedly connected to the end face of the two receiving plates near the raw material. The vertical plate, the baffle and the receiving plates are combined to form a receiving trough.

[0011] In a preferred embodiment of the automatic cotton grabber provided by this utility model, the bottom end of the middle part of the baffle is connected to the bottom end of the vertical plate by a hinge. A fixing strip is provided at the top end of the middle part of the baffle, and two limiting strips are provided at the top end of the vertical plate. The fixing strip is movably engaged between the two limiting strips. Positioning holes are provided on the surfaces of the limiting strips and the fixing strips, and bolts are connected between the three positioning holes.

[0012] In a preferred embodiment of the automatic cotton grabber provided by this utility model, the end of the protruding platform is configured as an inclined surface.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The beveled design at the end of the protruding platform can actively push the cotton wool on the surface of the sliding table forward during movement, preventing the cotton wool from accumulating in the gap between the protruding platform and the sliding table. This avoids the equipment from jamming or malfunctioning due to the cotton wool getting tangled in the drive components, while maintaining the flatness of the sliding table surface and ensuring the smooth movement of the sliding base. When the sliding base moves, the protruding platform drives the central shaft of the cleaning mechanism to move along the sliding platform. Simultaneously, through the meshing of the second gear and the rack in the sliding platform groove, the first gear and the central shaft are driven to rotate, causing the cleaning disc to rotate synchronously during the movement. This purely mechanical design, which requires no additional power source, reduces energy consumption and equipment complexity, and has high transmission efficiency. The cleaning action is synchronized with the movement of the cotton grabber, achieving cleaning while moving. The cleaning disc rotates close to the ground, sweeping up residual cotton fibers. Combined with the thrust and airflow during the movement of the cleaning disc, the cotton fibers are pushed towards the collecting mechanism, preventing them from scattering and accumulating, keeping the working environment clean, and reducing material waste. The receiving trough, composed of a vertical plate, a baffle, and a receiving plate, forms a three-sided enclosed space. When the cleaning disc pushes the cotton lint towards the vertical plate, the baffle can prevent the cotton lint from scattering forward, causing it to accumulate in the trough. This results in high collection efficiency and prevents spillage. The baffle is connected to the vertical plate via hinges, and the top fixing strip and the limiting strip are locked with bolts to form a rigid structure. When unloading, simply loosen the bolts, and the baffle can rotate 90 degrees around the hinge to open the front opening of the receiving trough, facilitating the dumping of cotton lint. The operation is simple and quick, reducing the workload and time cost of manual cleaning. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] As described in the background section, cotton grabbers lack a cleaning mechanism for the working area. Cotton lint that falls during the grabbing process tends to accumulate on the surface of the sliding table and the transmission parts of the equipment, increasing the risk of equipment failure and requiring frequent shutdowns for cleaning, which reduces production continuity and equipment lifespan.

[0019] To solve this technical problem, this utility model provides an automatic cotton grabbing machine, which includes a cotton grabbing mechanism 1. A sliding base 2 is fixedly installed below the cotton grabbing mechanism 1. A sliding platform 3 is provided below the sliding base 2. A groove is provided in the middle of the bottom of the sliding base 2. The sliding base 2 slides and engages with the sliding platform 3 through the groove. Cleaning mechanisms 4 are provided at both ends of the bottom of the sliding base 2 and near the raw material. A material receiving mechanism is provided at the end of the sliding base 2 near the raw material. The material receiving mechanism is located between the two cleaning mechanisms 4.

[0020] This automatic cotton grabber achieves high efficiency, cleanliness, and reliability in cotton grabbing through its integrated design. With the help of the cleaning mechanism 4 and the material collection mechanism, it can clean up and collect cotton lint that has fallen into the raw materials, thereby improving overall production efficiency and equipment stability.

[0021] Example 1 Please refer to Figure 1 : The bottom of the sliding base 2 has protruding plates 15 at both ends, and the protruding plates 15 slide on the top of the sliding table 3; The protruding platform 15 can cooperate with the cleaning mechanism 4, and the protruding platform 15 can remove the cotton lint on the surface of the sliding table 3 in a timely manner, prevent the cotton lint from getting tangled in the drive components, reduce the risk of equipment jamming or failure, avoid the accumulation of cotton lint causing unevenness on the surface of the sliding table 3, ensure the matching accuracy between the protruding platform 15 and the sliding table 3, and maintain the stability of the movement of the sliding base 2.

[0022] The end of the protruding platform 15 is set as a slope; The design of this inclined surface can push the cotton wool on the surface of the sliding table 3 to the front end of the cleaning mechanism 4 in the direction of movement during the movement.

[0023] Example 2 Further optimizations to Example 1, specifically, such as... Figure 2-4 As shown: The cleaning mechanism 4 includes a cleaning disc 5, which is close to the ground. A central shaft is fixedly installed at the center of the cleaning disc 5, and the top of the central shaft is rotatably connected to a protruding plate 15. When the sliding base 2 moves along the sliding table 3, the protruding table 15 slides synchronously, and the central axis at its bottom drives the cleaning disc 5 to move on the ground. As the cleaning disc 5 moves and rotates, it can clean up the residual cotton wool on the ground and collect it into the material collection mechanism.

[0024] A first gear 6 is fixedly installed on the surface of the central shaft near the top. A slide groove 8 is opened on the surface of the sliding table 3 near the raw material. A rack 9 is installed on the inner wall of the slide groove 8. A second gear 7 is installed between the first gear 6 and the slide groove 8. The middle part of the second gear 7 is connected to a protruding platform 15 through a rotating shaft. The surface of the second gear 7 meshes with the rack 9 and the first gear 6 respectively. When the sliding base 2 drives the protruding platform 15 to move along the sliding table 3, the second gear 7 slides in the sliding groove 8 along with the protruding platform 15. Its tooth surface meshes with the fixed rack 9. Because the rack 9 is stationary, it is forced to rotate. The rotation of the second gear 7 is transmitted to the first gear 6 through the meshing relationship, which drives the central shaft to rotate synchronously, and finally drives the cleaning disc 5 to rotate.

[0025] The receiving mechanism includes two receiving plates 12. A vertical plate 10 is fixedly installed on the sliding base 2 near the middle of the raw material. The two receiving plates 12 are respectively installed at both ends of the vertical plate 10. A baffle 11 is fixedly connected to the end face of the two receiving plates 12 near the raw material. The vertical plate 10, the baffle 11 and the receiving plates 12 are combined to form a receiving trough. When the sweeping disc 5 sweeps up the cotton wool on the ground, the cotton wool moves towards the upright plate 10 due to the pushing force of the sweeping disc 5 and the airflow. The baffle 11 prevents the cotton wool from falling forward and eventually accumulates in the collection trough.

[0026] The bottom of the middle part of the baffle 11 is connected to the bottom of the upright plate 10 by a hinge. The top of the middle part of the baffle 11 is provided with a fixing strip 13, and the top of the upright plate 10 is provided with two limiting strips 14. The fixing strip 13 is movably engaged between the two limiting strips 14. The surfaces of the limiting strips 14 and the fixing strip 13 are provided with positioning holes, and bolts are connected between the three positioning holes. The fixing strip 13 is inserted between the two limiting strips 14, and the positioning holes of the three are aligned. The bolt is passed through the positioning hole and tightened. The baffle 11 and the upright plate 10 form a rigid connection. At this time, the baffle 11 is perpendicular to the receiving trough, preventing the material from overflowing and forming a locked state. When the bolt is loosened and pulled out, the fixing strip 13 is released from the constraint of the limiting strip 14, and the baffle 11 can be rotated ninety degrees around the hinge. The opening at the front end of the receiving trough is opened, and the cotton can be poured out from the trough.

[0027] Example 3 Further optimizations to Example 2, such as Figure 1 , 5 As shown: The traditional JWF1018 cotton grabber relies on manually setting a fixed descent amount for its cotton grabbing capacity. Its cotton grabbing efficiency is affected by the pressure fluctuations in multiple bins, and it is consistently below 90%. Furthermore, operators need to frequently adjust the parameters manually based on the full status of the multiple bins. The JWF1018 cotton grabber program was modified, and the following quantitative settings were determined: the cotton grabbing efficiency sampling cycle is 5 minutes, the upper limit of cotton grabbing efficiency is 96%, the lower limit is 88%, the maximum drop is 4, and the manual / automatic cotton grabbing efficiency switching option was set. Adjustable settings: Automatic compensation amount, upper and lower limit compensation amount gain; PLC calculation process: Take the average value of the cotton grabbing efficiency over the past 10 sampling periods as the current cotton grabbing efficiency S; 92% of the average value of the upper and lower limits of the cotton grabbing efficiency is S1; the automatic compensation amount is M; the upper and lower limit compensation amount gain is K; and the previous decrease amount is G. Current decrease = (S-S1)*M*K+G; Through technological upgrades, the cotton grabbing speed of the JWF1018 has been automatically adjusted from manual adjustment, stabilizing cotton supply in multiple warehouses without manual intervention. After the upgrades, the cotton grabbing machine's operating efficiency remains above 95%. All three machines have undergone the upgrades, greatly improving equipment operating efficiency, reducing the labor intensity of operators, and realizing automatic control and digital empowerment.

[0028] The automatic cotton grabber provided by this utility model is used as follows: First, the cotton-grabbing mechanism 1 is fixedly installed above the sliding base 2. The sliding base 2 forms a sliding engagement with the sliding table 3 through a bottom groove. When the sliding base 2 moves along the sliding table 3, it drives the cotton-grabbing mechanism 1 to complete the cotton-grabbing operation. At the same time, the protruding platform 15 at the bottom slides synchronously on the top of the sliding table 3. When the sliding base 2 moves, the protruding platform 15 drives the cleaning disc 5 to move synchronously on the ground, initially pushing the cotton lint towards the collecting mechanism. A rack 9 is fixed in the groove 8 on the surface of the sliding table 3. The protruding platform 15 is connected to the second gear 7 through a rotating shaft. The second gear 7 meshes with both the rack 9 and the first gear 6. When the protruding platform 15 slides along the groove 8, the second gear 7 is forced to rotate because the rack 9 is stationary. The gear 6 rotates, which in turn drives the central shaft to rotate, causing the sweeping disc 5 to rotate synchronously during movement. The rotating sweeping disc 5 uses centrifugal force and mechanical thrust to efficiently sweep up residual cotton fibers on the ground and push them toward the collection mechanism. Finally, after the sweeping disc 5 sweeps up the cotton fibers, the cotton fibers move toward the vertical plate 10 under the action of thrust and airflow. The collection trough formed by the collection plate 12 and the baffle 11 prevents the cotton fibers from scattering and accumulates in the trough. The fixing strip 13 is inserted between the limiting strip 14, and the bolt is tightened through the positioning hole. The baffle 11 is perpendicular to the collection trough to prevent the cotton fibers from overflowing. When the bolt is loosened and pulled out, the baffle 11 rotates 90 degrees around the hinge, and the opening at the front end of the collection trough opens, allowing the cotton fibers to be poured out.
