[0044] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figure 1-9 This utility model provides a technical solution: a gripping roller for a bag-grabbing machine, comprising:

[0046] The cotton grabbing unit 4 is located on one side of the liftable cotton grabbing machine body 3 and above the conveyor 1, and is used to grab the cotton material on the conveyor 1.

[0047] Cotton-grabbing unit 4 includes:

[0048] The cotton grabbing assembly is mounted on the cotton grabbing machine body 3 and moves up and down with the cotton grabbing machine body 3 to grab cotton material;

[0049] The pressing component 44 is located on both sides of the cotton gripping component and is used to press the sides of the cotton material when the cotton gripping component grips the cotton material.

[0050] It should be noted that during operation, when grabbing cotton material on conveyor 1, the cotton grabbing machine body 3 is activated, causing it to reciprocate on the electric slide rail 2 on one side of conveyor 1. The cotton grabbing unit 4 connected to the cotton grabbing machine body 3 grabs the cotton material on conveyor 1. During the process of the cotton grabbing assembly grabbing the cotton material, the pressing component 44 can press the cotton material on both sides of the cotton grabbing assembly, effectively preventing the cotton material from loosening and shifting, making the cotton material more compact, reducing the gaps in the cotton material, improving the density and uniformity of the cotton material, ensuring that the amount of cotton material grabbed is uniform, effectively reducing the transmission error and equipment failure caused by the problem of cotton material entanglement on the cotton grabbing assembly, improving the cotton grabbing effect and quality, and extending the service life of the equipment.

[0051] In one embodiment, the cotton-grabbing assembly includes: a housing 41 disposed on one side of the cotton-grabbing machine body 3; a beater disposed inside the housing 41; a power assembly 432 disposed on the side of the housing 41 near the cotton-grabbing machine body 3 and connected to the beater, for driving the beater to rotate; and a partition 42 disposed at the lower end of the interior of the housing 41 for protecting the components inside the housing 41. The power assembly 432 includes a motor and a transmission assembly, which are existing technologies and will not be described in detail here.

[0052] This design is for reference. Figure 4 The cotton grabber body 3 adjusts the installation height of the housing 41 so that the beater is in contact with the upper end of the cotton material. The power component 432 is started to drive the beater to rotate. The centrifugal force and airflow generated by the beater during rotation can effectively separate the cotton material from the raw material pile and grab it into the housing 41, improving the efficiency and accuracy of cotton grabbing. The partition 42 is set at the lower end of the inside of the housing 41. Its main function is to protect the components inside the housing 41. It can effectively block the raw cotton material, control the amount of cotton material fed, and protect the internal components of the housing 41 from damage, extend the service life of the components, reduce the maintenance cost and downtime of the equipment, and improve the reliability and stability of the equipment.

[0053] In one embodiment, the beater includes: a beater roller 43, disposed inside the housing 41 and connected to the power assembly 432; and blades 431, arranged in a semi-circular arc and arranged in a spiral array on the outer end face of the beater roller 43, for breaking up and grasping the cotton material.

[0054] This design is for reference. Figure 4 ,as well as Figure 5The beater roller 43 is housed inside the housing 41 and connected to the power assembly 432. This direct and tight connection ensures that power can be efficiently and stably transmitted from the power assembly 432 to the beater roller 43. Compared to a complex transmission structure, this reduces energy loss and potential transmission failures during power transmission, allowing the beater roller 43 to rotate at a stable speed. This provides reliable power support for the blades 431 to break up and grasp the cotton, thereby improving the efficiency of cotton grasping. The blades 431 are semi-circularly arranged and arranged in a spiral array on the outer end face of the beater roller 43. This unique design allows the blades 431 to contact the cotton at a specific angle and in a specific manner as they rotate with the beater roller 43. The semi-circular shape better conforms to the shape of the cotton. During rotation, the blades 431... It can penetrate deep into the cotton material and effectively break up clumps of cotton. The spirally arranged blades 431 generate a spiral propulsion effect during rotation. When impurities or long fibers in the cotton material are wrapped around the blades 431, this spiral motion helps to gradually push the impurities and wrapped fibers outward, reducing the accumulation of impurities and fiber entanglement on the surface of the blades 431. This keeps the blades 431 clean and sharp, extends the service life of the blades 431, and also reduces equipment failures and downtime caused by blade entanglement, thus improving the operating efficiency and stability of the equipment.

[0055] In one embodiment, the pressing assembly 44 includes: a mounting box 441 disposed on both sides of the box body 41; a connecting shaft 442 disposed at intervals inside the mounting box 441; and a squeezing roller 443 sleeved on the connecting shaft 442 and extending downward out of the mounting box 441 for squeezing the cotton material.

[0056] This design is for reference. Figure 6-9 The mounting boxes 441 are located on both sides of the box body 41. This symmetrical layout makes the pressing component 44 exert a more uniform force when squeezing the cotton. Applying force from both sides at the same time can prevent the cotton from shifting or deforming due to force on one side. The squeezing roller 443 is sleeved on the connecting shaft 442 and extends downward from the mounting box 441. This design allows the squeezing roller 443 to directly contact and squeeze the cotton. During the cotton grabbing process, the cotton that has been broken up and grabbed by the beater may have a certain degree of looseness and unevenness. The squeezing action of the squeezing roller 443 can make the cotton more compact, reduce the gaps in the cotton, and improve the density and uniformity of the cotton. The compacted cotton is easier to handle in the subsequent conveying and combing process, which can improve the efficiency and quality of the entire cotton processing process and reduce the phenomenon of cotton getting tangled in the beater roller 43.

[0057] In one embodiment, the pressing assembly 44 further includes: a connecting block 444 disposed on the side where the connecting shaft 442 is connected to the mounting box 441; a first rack 446 disposed on the upper end of a connecting block 444; a mounting shaft 448 disposed inside the mounting box 441; a gear 447 sleeved on the mounting shaft 448 and meshing with the first rack 446; and a second rack 449 disposed on the upper end of another connecting block 444 and meshing with the gear 447; the first rack 446 and the second rack 449 are symmetrically arranged about the gear 447.

[0058] This design is for reference. Figure 6-9 The first rack 446 is disposed on the upper end of a connecting block 444, and the second rack 449 is disposed on the upper end of another connecting block 444. The two racks are symmetrically arranged about the gear 447 and are respectively meshed with the gear 447. When the cotton material is fed too much into the connecting block 444 on one side of the first rack 446 due to the action of the beater roller 43 and the blade 431, causing the extrusion roller 443 connected to the first rack 446 to move upward, the first rack 446 will be driven upward through the connecting block 444, thereby causing the gear 447 to drive, which in turn drives the second rack 449 and the other connecting block 444 connected to it to move downward synchronously. This increases the pressing force of the other extrusion roller 443 on the cotton material, which can prevent the cotton material from getting too much gripped and getting tangled on the beater roller 43, thus improving the uniformity and stability of the cotton material processing.

[0059] In one embodiment, a slider 4441 is provided at the position where the connecting block 444 is connected to the mounting box 441, and the mounting box 441 is provided with a groove 44101 for the slider 4441 to move. An elastic element 445 is provided at the upper end of the groove 44101. The elastic element 445 is made of a damped spring or an elastic pad.

[0060] This design is for reference. Figure 6-8The slider 4441 is slidably connected to the groove 44101 on the mounting box 441. This design provides precise movement guidance for the connecting block 444. During the operation of the pressing assembly 44, when the connecting block 444 moves with the increasing amount of cotton material, the sliding of the slider 4441 in the groove 44101 ensures that the connecting block 444 moves smoothly in the predetermined direction, avoiding deviation or shaking of the connecting block 444 during movement. This ensures the accuracy and stability of the squeezing roller 443 on the cotton material and improves the cotton gripping quality. The elastic element 445 is located at the upper end of the groove 44101 above the slider 4441. When the connecting block 444 moves upward, it squeezes the elastic element 445. The elastic element 445 applies a downward preload to the slider 4441, so that the squeezing roller 443 can move downward when it is not subjected to external force, maintaining its normal working position and maintaining a certain squeezing force on the cotton material, ensuring effective squeezing of the cotton material.

The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
