Description

Technical Field

[0001] The present invention relates to the technical field of the textile industry, specifically to the gripper roller of a bale opener. Background Art

[0002] In the textile industry, a bale opener is a key device used to grab cotton fibers from a bale of cotton or other cotton materials and transport them to subsequent processing steps. During the process of grabbing cotton materials by the traditional gripper roller of a bale opener, problems such as cotton material entanglement, uneven grabbing, and insufficient compactness of the cotton material often occur.

[0003] The existing equipment has the following disadvantages: The compactness of the cotton material grabbed by the traditional gripper roller is insufficient, and there are many voids in the cotton material. Due to the characteristics of cotton fibers being slender, soft, and easily entangled with each other, when the gripper roller grabs the cotton material, the cotton fibers are easily wound around the gripper roller, resulting in a decrease in the grabbing efficiency of the gripper roller, and even possibly causing equipment failures, affecting the continuity and stability of production. At the same time, the entangled cotton material will also increase the cleaning difficulty and maintenance cost of the equipment.

[0004] Therefore, the present application now proposes a gripper roller for a bale opener to solve the above-mentioned problems. Summary of the Invention

Detailed implementation manners

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] Please refer to Figures 1-11 , the present invention provides a technical solution: a gripper roller of a packet capture machine, including: a cotton grabbing unit 4, arranged on one side of a liftable cotton grabbing machine body 3 and above a conveyor 1, for grabbing cotton material on the conveyor 1; the cotton grabbing unit 4 includes: a cotton grabbing assembly, arranged on the cotton grabbing machine body 3 and moving up and down with the cotton grabbing machine body 3, for grabbing cotton material; an extrusion assembly 44, arranged on both sides of the cotton grabbing assembly, for extruding both sides of the cotton material when the cotton grabbing assembly grabs the cotton material; a hammering mechanism 445, arranged on both sides of the extrusion assembly 44 and connected to the extrusion assembly 44, moving with the extrusion assembly 44, for hammering the cotton material on both sides of the extrusion assembly 44.

[0060] It should be noted that during operation, when grabbing the cotton material on the conveyor 1, the cotton grabbing machine body 3 is started to reciprocate on the electric slide rail 2 on one side of the conveyor 1. The cotton grabbing unit 4 connected to the cotton grabbing machine body 3 grabs the cotton material on the conveyor 1. And during the process of the cotton grabbing assembly grabbing the cotton material, the extrusion assembly 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 voids in the cotton material. The hammering mechanism 445 further hammers the cotton material, improving the density and uniformity of the cotton material, ensuring that the amount of grabbed cotton material is uniform, effectively reducing the transmission error and equipment failure caused by the problem of the cotton material winding on the cotton grabbing assembly, improving the effect and quality of cotton grabbing, and extending the service life of the equipment.

[0061] In one embodiment, the cotton grabbing assembly includes: a box body 41, arranged on one side of the cotton grabbing machine body 3; a beater, arranged inside the box body 41; a power assembly 432, arranged on the side of the box body 41 close to the cotton grabbing machine body 3 and connected to the beater, for driving the beater to rotate; a partition 42, arranged at the lower end inside the box body 41, for protecting the components inside the box body 41.

[0062] With such a design, refer to Figures 1-6, the bale opener body 3 adjusts the installation height of the box body 41 so that the beater fits the upper end of the cotton material. The power component 432 is started to drive the beater to rotate. The centrifugal force and air flow generated during the rotation of the beater can effectively separate and grab the cotton material from the raw material pile into the box body 41, improving the efficiency and accuracy of cotton grabbing. The partition 42 is arranged at the lower end inside the box body 41. Its main function is to protect the components inside the box body 41, can effectively block the cotton material raw materials, control the feeding amount of the cotton material, and protect the components inside the box body 41 from damage, extending the service life of the components, reducing the maintenance cost and downtime of the equipment, and improving the reliability and stability of the equipment.

[0063] In one embodiment, the beater includes: a beater roll 43 arranged inside the box body 41 and connected to the power component 432; a blade 431 arranged in a semi-circular arc and in a spiral array on the outer circumferential end face of the beater roll 43 for dispersing and grabbing the cotton material.

[0064] With such a design, referring to Figure 6 , the beater roll 43 is arranged inside the box body 41 and connected to the power component 432. This direct and tight connection method ensures that power can be efficiently and stably transmitted from the power component 432 to the beater roll 43. Compared with complex transmission structures, it reduces the energy loss and possible transmission failures during power transmission, enabling the beater roll 43 to rotate at a stable speed, providing reliable power support for the work of the blade 431 to disperse and grab the cotton material, thus improving the efficiency of cotton grabbing work. The blade 431 is arranged in a semi-circular arc and in a spiral array on the outer circumferential end face of the beater roll 43. This unique design enables the blade 431 to contact the cotton material at a specific angle and in a specific manner when rotating with the beater roll 43. The semi-circular arc shape can better fit the shape of the cotton material. During rotation, the blade 431 can penetrate into the cotton material and effectively disperse the agglomerated cotton material. The spirally arranged blades 431 will generate a spiral propulsion effect during rotation. When impurities or long fibers in the cotton material are wound around the blade 431, this spiral movement helps to gradually push the impurities and wound fibers outward, reducing the impurity accumulation and fiber winding on the surface of the blade 431, thus keeping the blade 431 clean and sharp, extending the service life of the blade 431, and also reducing equipment failures and downtime caused by blade 431 winding, improving the operation efficiency and stability of the equipment.

[0065] In one embodiment, the extrusion component 44 includes: a mounting box 441 symmetrically arranged on both sides of the box body 41; a connecting shaft 4434 arranged inside the mounting box 441; an extrusion roll 444 sleeved on the connecting shaft 4434 for extruding the cotton material on both sides of the beater roll 43.

[0066] With such a design, referring toFigure 4 , Figure 7 , the installation boxes 441 are arranged on both sides of the box body 41. This symmetrical layout makes the acting force more uniform when the squeezing assembly 44 squeezes the cotton material. Applying force on both sides simultaneously can prevent the cotton material from shifting or deforming due to unilateral force. The squeezing roller 444 is sleeved on the connecting shaft 4434 and extends downward out of the installation box 441. This design enables the squeezing roller 444 to directly contact the cotton material and squeeze it. During the cotton grabbing process, the cotton material grabbed and dispersed by the beater may have a certain degree of looseness and unevenness. The squeezing effect of the squeezing roller 444 can make the cotton material more compact, reduce the voids in the cotton material, improve the density and uniformity of the cotton material. The compact cotton material is easier to process during subsequent conveying and carding processes, which can improve the efficiency and quality of the entire cotton processing process and reduce the phenomenon of the cotton material winding around the beater roller 43.

[0067] In one embodiment, the squeezing assembly 44 further includes: a power mechanism 442, which is arranged inside the installation box 441 and is connected to the connecting shaft 4434 for driving the squeezing roller 444 to rotate; the power mechanism 442 includes: a motor 4421, which is arranged inside the installation box 441; a rotating shaft 4422, which is arranged at the power output end of the motor 4421; a transmission mechanism 443, which is arranged on the side of the rotating shaft 4422 away from the motor 4421 for transmitting kinetic energy. The transmission mechanism 443 includes: a first gear 4431, which is fixedly sleeved on the rotating shaft 4422, a second gear 4433, which is fixedly sleeved on the connecting shaft 4434; a transmission chain 4432, which is sleeved on the first gear 4431 and the second gear 4433.

[0068] With this design, referring to Figures 8-10 , start the motor 4421, drive the rotating shaft 4422 to drive the transmission mechanism 443 to move. The first gear 4431 in the transmission mechanism 443 drives the transmission chain 4432 to rotate, and then the second gear 4433 drives the connecting shaft 4434 to move, making the squeezing roller 444 rotate to squeeze the cotton material on the conveyor 1. According to the tooth number ratio of the first gear 4431 and the second gear 4433, different speed change effects can be achieved, thereby adjusting the rotation speed of the squeezing roller 444 to adapt to the squeezing requirements of different cotton materials, which helps to improve the compactness and uniformity of the cotton material, provides better raw material conditions for subsequent processing procedures, and improves the product quality.

[0069] In one embodiment, the hammering mechanism 445 includes: a transmission member, which is arranged inside the installation box 441 and is connected to the connecting shaft 4434; a lifting member, which is arranged inside the installation box 441 and is connected to the transmission member and moves up and down under the drive of the transmission member; a striking plate 4458, which is arranged on the lifting member and moves up and down with the lifting member for hammering and loosening the cotton material.

[0070] With this design, referring toFigures 7-10 During the rotation of the connecting shaft 4434, the lifting member will be driven by the transmission member to reciprocate up and down inside the mounting box 441. The striking plate 4458 is arranged on the lifting member and moves up and down with it, directly striking and loosening the cotton material, effectively breaking the fiber entanglement and caking in the cotton material, improving the looseness and air permeability of the cotton material, which helps the smooth progress of subsequent processing procedures and improves the quality and performance of the yarn.

[0071] In one embodiment, the hammering mechanism 445 further includes: inserting pins 4459, which are arranged at intervals at the lower end of the striking plate 4458 and are used for loosening the cotton material.

[0072] With this design, referring to Figures 7-10 , the inserting pins 4459 are arranged at intervals at the lower end of the striking plate 4458. When the striking plate 4458 moves up and down with the lifting member to strike the cotton material, the inserting pins 4459 can penetrate into the interior of the cotton material. Compared with the simple striking of the striking plate 4458, the inserting pins 4459 can act more directly on the fiber entanglement and caking parts inside the cotton material, effectively breaking the connection between the fibers, making the cotton material start to loosen from the inside, improving the thoroughness of loosening. While the striking plate 4458 strikes the cotton material, multiple inserting pins 4459 act on different parts of the cotton material simultaneously, capable of loosening the cotton material more comprehensively, avoiding the situation of uneven local loosening, and making the looseness of the entire cotton layer more consistent.

[0073] In one embodiment, the transmission member includes: a third gear 4451, which is sleeved on the connecting shaft 4434 and rotates together with the connecting shaft 4434; a support shaft 4453, which is arranged inside the mounting box 441; and a fourth gear 4452, which is sleeved on the support shaft 4453 and is meshed and connected with the third gear 4451.

[0074] With this design, referring to Figure 11 , the third gear 4451 is sleeved on the connecting shaft 4434 and rotates together with it, capable of directly transmitting the power of the connecting shaft 4434 to the fourth gear 4452. The synchronous rotation of the third gear 4451 and the connecting shaft 4434 realizes the motion correlation between the power of the extrusion assembly 44 and the hammering mechanism 445. When the extrusion roller 444 rotates to extrude the cotton material, the third gear 4451 is driven to rotate by the connecting shaft 4434, and then the hammering mechanism 445 is driven to work, making the extrusion and hammering actions able to coordinate and cooperate, improving the coherence and efficiency of cotton material processing.

[0075] In one embodiment, the lifting member includes: a cam 4454 disposed on a side of the support shaft 4453 away from the mounting box 441; a mounting shaft 4455 disposed on the cam 4454 and eccentrically disposed with respect to the support shaft 4453; a collar 4456 sleeved on the mounting shaft 4455; a rotating rod 44510 disposed at the lower end of the collar 4456; and a push rod 4457 disposed at the lower end of the rotating rod 44510 and connected to the striking plate 4458.

[0076] With this design, referring to Figures 9-11 , the cam 4454 is disposed on a side of the support shaft 4453 away from the mounting box 441. When the support shaft 4453 drives the cam 4454 to rotate, the special contour shape of the cam 4454 enables the mounting shaft 4455 to perform an eccentric motion along a predetermined trajectory. This eccentric motion is the key to realizing the up and down movement of the striking plate 4458. By reasonably designing the contour curve of the cam 4454, the movement stroke, speed, and acceleration of the striking plate 4458 can be precisely controlled to meet the requirements of different cotton material processing processes. The mounting shaft 4455 is disposed on the cam 4454 and is eccentrically disposed with respect to the support shaft 4453. It can convert the rotational motion of the cam 4454 into its own eccentric rotational motion. This eccentric motion is transmitted to the striking plate 4458 through the collar 4456, the rotating rod 44510, and the push rod 4457, enabling it to perform a straight up and down motion. It is an important link for the lifting member to achieve motion conversion.

[0077] In one embodiment, a support frame 4411 for supporting the push rod 4457 is disposed inside the mounting box 441 at a position corresponding to the push rod 4457.

[0078] With this design, referring to Figures 9-11 , by disposing the support frame 4411 inside the mounting box 441 at a position corresponding to the push rod 4457, an additional support force can be provided for the push rod 4457. During the up and down movement of the push rod 4457, the support frame 4411 bears part of the force and torque, reducing the force deformation of the push rod 4457 itself, ensuring the motion accuracy and stability of the push rod 4457, and enabling it to accurately transmit the motion to drive the striking plate 4458 to perform an up and down hammering action.
