Description

Technical Field

[0001] The invention relates to the technical field of textile processing equipment, in particular to a wool roll pushing mechanism for a wool baling machine. Background Art

[0002] A balling machine is a textile processing equipment used to wrap and pack the combed wool strips to reduce their volume for easy transportation. Figure 1 and Figure 2 The machine body shown in the figure only represents a part of the ball forming machine, which is mainly located at the tail end of the ball forming machine. Its function is to wind the combed fiber strips through the winding roller to form wool balls (wool rolls), and then cut the fiber strips through the shearing mechanism in the machine body, and then drive the winding roller to rotate toward the discharge plate through the rocker arm, so that one end of the winding roller is just embedded in the positioning groove of the discharge plate, and the internal driving structure of the machine body drives the discharge plate to push the wool balls, thereby pushing the wool balls from one end of the winding roller to the other end. When the wool balls are separated from the winding roller, they fall into the tray to complete the collection.

[0003] The current technical problem is: in the process of the wool ball moving from one end of the winding roller to the other, the inside of the wool ball will rub against the rigid outer surface of the winding roller, which can easily tear the inside of the wool ball apart and cause partial breakage of the fiber strips inside the wool ball. This phenomenon is more obvious when the surface of the winding roller is relatively rough. Therefore, a new structure needs to be designed to solve this problem. Summary of the invention

The movable plates have a supporting surface for supporting the wool roll instead of the circumferential surface of the winding roller. The supporting surfaces of all the movable plates are located on the circumferential surface of the same virtual cylinder. The axis lines of the virtual cylinder and the winding roller coincide with each other. The movable plates are made of bending-resistant material and are slidably connected to the winding roller. When in use, the unloading plate pushes the movable plate and the wool roll it carries to move along the surface of the winding roller, so that when the part of the movable plate that is separated from the support of the winding roller cannot withstand the weight of the wool roll and bends, thereby releasing the wool roll.

[0009] As a preferred technical solution of the present invention, the pushing mechanism further includes a rocker arm having one end rotatably connected to the machine body, and the other end of the rocker arm is rotatably connected to the winding roller.

[0016] As a preferred technical solution of the present invention, a positioning plate is provided on the inner side of the movable plate, and a positioning sleeve is provided on the side of the positioning plate facing the movable block. The positioning sleeve is plug-in-fit with the positioning hole opened in the movable block, and bolts are provided in the positioning sleeve and the positioning hole.

[0017] As a preferred technical solution of the present invention, an end shaft is provided at one end of the winding roller, the end shaft is connected to the rocker arm bearing, the end shaft is rotatably connected to a rotating sleeve, the rotating sleeve is connected to the exhaust end of the exhaust fan, and an air hole connecting the rotating sleeve and the inner cavity of the winding roller is opened at one end of the winding roller, and a plurality of suction grooves are provided on the surface of the winding roller, and the wool strips can be adsorbed on the suction grooves on the surface of the winding roller through the exhaust fan.

[0021] Beneficial effects of the present invention: The present invention forms a virtual cylindrical support by slidingly arranging multiple movable plates on the winding roller, so that the support replaces the winding roller to support the wool roll. When the unloading plate pushes the movable plate and the wool roll it carries to move along the surface of the winding roller, the right end of the movable plate will first separate from the winding roller. The movable plate that loses the support of the winding roller will partially shrink inward along the radial direction of the virtual cylinder, reducing the supporting force of the movable plate on the wool roll. Finally, the wool roll bends the movable plate by its own weight and separates from it. In this process, the movable plate changes from rigidity to flexibility, effectively preventing the inside of the wool roll from being torn apart due to friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] like Figure 3 , Figure 4 and Figure 6 As shown, a wool roll pushing mechanism for a wool baling machine comprises: a discharge plate 4; a driving structure connected to a machine body 1, the driving structure being used to drive the discharge plate 4 to move along the axis direction of the winding roller 3 so as to push the wool roll off the winding roller 3; a plurality of movable plates 11 arranged in a ring shape on the circumferential surface of the winding roller 3 about the axis of the winding roller 3, the movable plates 11 having a supporting surface for supporting the wool roll instead of the circumferential surface of the winding roller 3, the supporting surfaces of all movable plates 11 being located on the circumferential surface of the same virtual cylinder, the axis of the virtual cylinder and the winding roller 3 being coincident with each other, the movable plates 11 being made of a bending-resistant material and being slidably connected to the winding roller 3, when in use, the discharge plate 4 pushes the movable plates 11 and the wool roll carried by them to move along the surface of the winding roller 3, so that when the portion of the movable plates 11 separated from the support of the winding roller 3 cannot bear the weight of the wool roll and bends, thereby releasing the wool roll;

[0037] The adoption of the above technical scheme can reduce the probability of the fiber strips being torn apart when the wool roll is unloaded. During use, as the winding roller 3 rotates, the wool strips are evenly wound on the winding roller 3, and more and more wool strips eventually form a wool roll on the winding roller 3. Since a movable plate 11 is provided on the circumferential surface of the winding roller 3, the wool roll does not directly contact the winding roller 3, but is supported by the supporting surface of the movable plate 11. When the wool roll is wound, the winding roller 3 stops rotating, the shearing mechanism in the machine body 1 cuts the wool strips, and the driving structure drives the unloading plate 4 to move along the axial direction of the winding roller 3, so that the unloading plate 4 pushes the movable plate 11 and the wool roll it carries to move along the surface of the winding roller 3. In the initial state, both ends of the movable plate 11 are supported by the two ends of the circumferential surface of the winding roller 3, which can provide sufficient balance support for the movable plate 11, so that the movable plate 11 is sufficient to support the weight of the wool roll, and as the movable plate 11 moves from left to right The right end of the movable plate 11 will be separated from the winding roller 3 first, causing the stability of the movable plate 11 to be gradually destroyed, until only the left end of the movable plate 11 is in conflict with the winding roller 3. At this time, the movable plate 11 cannot bear the weight of the wool roll and bends downward, causing the wool roll to separate from the movable plate 11 and fall. Since the movable plate 11 replaces the winding roller 3 to support the wool roll, the wool roll will move synchronously with the movable plate 11 during the process of the movable plate 11 being pushed, and the inside of the wool roll will hardly generate friction with the winding roller 3. Then, the wool roll is released through the bending deformation of the movable plate 11. In this process, the movable plate 11 that has lost the support of the winding roller 3 will partially shrink inward along the radial direction of the virtual cylinder, reducing the supporting force of the movable plate 11 on the wool roll, making the contact friction between the two smaller, and the supporting mode of the movable plate 11 on the wool roll is changed from rigid to flexible, which effectively prevents the inside of the wool roll from being torn apart due to friction, thereby achieving the technical effect of improving the wool processing quality.

[0038] It should be noted that the axis lines of the virtual cylinder and the winding roller 3 coincide with each other, which can ensure that the center of the wool roll always coincides with the axis line of the winding roller 3, preventing the winding roller 3 from being subjected to eccentric force from the wool roll when rotating, avoiding bending of the winding roller 3, helping to increase the service life of the winding roller 3, and at the same time ensuring the roundness of the appearance of the wool roll.

[0039] like Figure 3 As shown, in this embodiment, the pushing mechanism further includes a rocker arm 2 with one end rotatably connected to the machine body 1, and the other end of the rocker arm 2 is rotatably connected to the winding roller 3;

[0040] like Figure 3As shown, in this embodiment, the driving structure includes: a connecting rod 6 connected to the discharge plate 4 at one end, and the other end of the connecting rod 6 is slidably matched with a slide groove 7 provided in the body 1; a screw rod 8 rotatably provided in the slide groove 7, and the screw rod 8 is adapted to a screw rod groove 9 provided on the surface of the connecting rod 6; a motor 10 connected to the body 1, and the output shaft of the motor 10 is fixedly connected to the screw rod 8;

[0041] like Figure 2 and Figure 3 As shown, in this embodiment, a positioning groove 5 matching the cross-sectional shape of the winding roller 3 is provided at one end of the discharge plate 4, and the winding roller 3 can be driven to fit into the positioning groove 5 by rotating the rocker arm 2;

[0042] The adoption of the above technical scheme can ensure that the winding roller 3 can automatically contact the unloading plate 4 after the wool roll is wound, so as to facilitate the subsequent automatic unloading. When in use, after the winding roller 3 has wound the wool roll, the rocker arm 2 can be rotated to drive the winding roller 3 to embed into the positioning groove 5, and the motor 10 drives the screw rod 8 to rotate. The screw rod 8 cooperates with the screw rod groove 9 to drive the connecting rod 6 to slide along the slide groove 7. The connecting rod 6 drives the unloading plate 4 connected to it to push the movable plate 11, so that the movable plate 11 moves relative to the winding roller 3, thereby unloading the wool roll.

[0043] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the pushing mechanism further includes a movable block 14 fixedly connected to one end of the movable plate 11, the movable block 14 is slidably connected to the inner cavity provided in the winding roller 3, and a movable groove 13 adapted to the shape of the movable plate 11 is provided on the circumferential surface of the winding roller 3, and the movable block 14 can be pushed to drive all the movable plates 11 connected thereto to slide along the movable groove 13;

[0044] The above technical solution is adopted to ensure that all movable blocks 14 can form a stable whole. During use, when the unloading plate 4 pushes one of the movable plates 11, the movable plate 11 drives the movable block 14, and the movable block 14 drives all the movable plates 11 connected thereto to slide synchronously along the movable groove 13, ensuring that the movement speed of each part inside the wool roll is consistent, preventing the occurrence of differential speed, which causes the wool roll to be torn apart.

[0045] like Figure 8 and Fig. 9 As shown, in this embodiment, a positioning plate 17 is provided on the inner side of the movable plate 11, and a positioning sleeve 18 is provided on the side of the positioning plate 17 facing the movable block 14. The positioning sleeve 18 is plug-in-pull fit with a positioning hole 19 provided in the movable block 14, and bolts 20 are provided in the positioning sleeve 18 and the positioning hole 19;

[0046] By adopting the above technical solution, the movable plate 11 can be detachably mounted on the movable block 14. Since the movable plate 11 needs to be frequently bent and reset, it will eventually be damaged as the use time increases. It is particularly necessary to design it to be detachable. The movable plate 11 can be made of A5182 aluminum plate. Due to its excellent mechanical properties and material properties, it has the characteristic of being able to withstand repeated bending without breaking.

[0047] like Fig.10 As shown, in this embodiment, the guide rod 16 is provided with a threaded rod 22 at one end thereof away from the rocker arm 2, and the winding roller 3 is provided with an end cover 21 at one end thereof away from the rocker arm 2. The threaded rod 22 is plug-in-fitted with a through hole 23 provided on the surface of the end cover 21, and the threaded rod 22 is provided with a nut 24 and a washer 25 adapted thereto.

[0048] By adopting the above technical solution, the end cover 21 can be connected to the winding roller 3 in a detachable manner. When the movable plate 11 and the movable block 14 need to be removed, the nut 24 at the end of the threaded rod 22 is unscrewed using a tool, and the washer 25 is removed, so that the end cover 21 can be removed from one end of the winding roller 3, so that the movable plate 11 and the movable block 14 can be taken out from the winding roller 3.

[0049] like Figure 4 , Figure 5 and Figure 7 As shown, in this embodiment, an end shaft 28 is provided at one end of the winding roller 3, the end shaft 28 is connected to the bearing of the rocker arm 2, the end shaft 28 is rotatably connected to a rotating sleeve 29, the rotating sleeve 29 is connected to the exhaust end of the exhaust fan, an air hole 30 connecting the rotating sleeve 29 and the inner cavity of the winding roller 3 is opened at one end of the winding roller 3, and a plurality of suction grooves 31 are provided on the surface of the winding roller 3, and the wool strips can be adsorbed on the suction grooves 31 on the surface of the winding roller 3 by the exhaust fan;

[0050] The adoption of the above technical scheme can facilitate the winding roller 3 to reel in the wool roll. When the wool roll is wound, the winding roller 3 stops rotating, and the shearing mechanism in the machine body 1 cuts the wool strip, which will form a movable end at the feed end and the wool roll respectively. By providing an air suction groove 31 on the surface of the winding roller 3, the movable end of the wool strip can be adsorbed on the air suction groove 31 on the surface of the winding roller 3 through an exhaust fan, which facilitates the winding roller 3 to reel in the wool strip. There is no need to manually fix the movable end of the wool strip on the winding roller 3, and the efficiency is high.

[0051] like Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the radius of the virtual cylinder is greater than the radius of the winding roller 3, the movable plate 11 is provided with a resisting block 12 at one end thereof close to the rocker arm 2, and a plurality of scrapers 32 extending outwardly in the radial direction thereof are provided on the outer circumferential surface of the movable block 14, and the scrapers 32 are embedded in the suction grooves 31;

[0052] The above technical solution can prevent wool fibers from clogging the air suction groove 31. During use, when the unloading plate 4 pushes the movable block 14 to move, the scraper 32 on the surface of the movable block 14 will move synchronously. The scraper 32 moves along the air suction groove 31 on the surface of the winding roller 3 to scrape off the wool fibers in the air suction groove 31 to prevent clogging the air suction groove 31. At the same time, the resistance block 12 can contact the unloading plate 4 to increase the contact area between the unloading plate 4 and the movable plate 11, which is conducive to the unloading plate 4 to stably push the movable plate 11.

[0053] like Figure 4 and Figure 5 As shown, in this embodiment, a guide rod 16 is provided in the inner cavity of the winding roller 3, and the guide rod 16 is slidably matched with the guide groove 15 provided on the surface of the movable block 14, and a spring 27 is sleeved on the outer side of the guide rod 16, and an annular plate 26 is provided at both ends of the spring 27;

[0054] The adoption of the above technical solution can ensure that the movable plate 11 can automatically reset after the unloading plate 4 leaves the movable plate 11 and resets. During use, when the movable plate 11 moves from left to right, as the movable block 14 continues to approach the end cover 21, the spring 27 is compressed; when the unloading plate 4 is separated from the resistance block 12 on the surface of the movable plate 11, the spring 27 originally in a compressed state is able to release its elastic potential energy, thereby pushing the movable block 14 to continuously move away from the end cover 21, prompting the movable block 14 to drive all the movable plates 11 connected thereto to automatically reset.

[0055] Working principle: When in use, as the winding roller 3 rotates, the wool strip is evenly wound on the winding roller 3 to form a wool roll. Since a movable plate 11 is provided on the circumferential surface of the winding roller 3, the wool roll does not directly contact the winding roller 3, but is supported by the supporting surface of the movable plate 11. When the wool roll is wound, the winding roller 3 stops rotating, and the shearing mechanism in the machine body 1 cuts the wool strip. After the winding roller 3 has wound the wool roll, the swing arm 2 is rotated to drive the winding roller 3 to embed into the positioning groove 5, and the motor 10 drives the screw rod 8 to rotate. The screw rod 8 cooperates with the screw rod groove 9 to drive the connecting rod 6 to slide along the slide groove 7. The connecting rod 6 drives the unloading plate 4 connected thereto to push the resistance block 12, and the resistance block 12 drives the movable plate 11 to move relative to the winding roller 3.

[0056] Because in the initial state, both ends of the movable plate 11 are supported by the two ends of the circumferential surface of the winding roller 3, which can provide sufficient balance support for the movable plate 11, so that the movable plate 11 is sufficient to support the weight of the wool roll, and as the movable plate 11 moves from left to right, as the movable block 14 continues to approach the end cover 21, the spring 27 is compressed, and the right end of the movable plate 11 will be the first to separate from the winding roller 3, causing the stability of the movable plate 11 to be gradually destroyed, until only the left end of the movable plate 11 is in conflict with the winding roller 3. At this time, the movable plate 11 cannot bear the weight of the wool roll and bends downward, so that the wool roll separates from the movable plate 11 and falls onto the tray 33 on one side of the machine body 1. The replacement winding roller 3 supports the wool roll, so when the movable plate 11 is pushed, the wool roll will move synchronously with the movable plate 11, and the inside of the wool roll will hardly generate friction with the winding roller 3. Then, the wool roll is released through the bending deformation of the movable plate 11. In this process, the movable plate 11 that loses the support of the winding roller 3 will partially shrink inward along the radial direction of the virtual cylinder, and the supporting mode of the movable plate 11 on the wool roll is changed from rigid to flexible, reducing the supporting force of the movable plate 11 on the wool roll, so that the contact friction between the two is small, thereby effectively reducing the situation that the inside of the wool roll is torn apart when the wool roll is detached from the movable plate 11, and even the wool fiber is broken, thereby achieving the technical effect of improving the wool processing quality;

[0057] When the unloading plate 4 is separated from the abutment block 12 on the surface of the movable plate 11, the spring 27 which was originally in a compressed state releases its elastic potential energy, thereby pushing the movable block 14 to continuously move away from the end cover 21, so that the movable block 14 drives all the movable plates 11 connected thereto to automatically reset.

[0058] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
