Description

Technical Field

[0001] This utility model relates to a waste edge traction mechanism. Background Technology

[0002] Currently, in the sheet material production process, it is usually necessary to cut off the uneven parts on the sides of the sheet to obtain sheet products with flat sides. The cut-off parts on the sides of the sheet form waste edges, which are typically traction-driven and conveyed to a crusher for crushing. Chinese Patent CN219652329U discloses a buffer traction device to prevent the breakage of diaphragm waste edges. This buffer traction device has upper and lower traction rollers that can clamp the waste edges and pull them along. However, the center positions of the two traction rollers in this buffer traction device are fixed, resulting in a fixed distance between them. Due to unavoidable dimensional and assembly errors in the traction rollers, these errors can cause the two traction rollers with a fixed distance to not fit tightly together, thus failing to stably clamp the waste edges. In addition, the traction rollers also experience vibration and wear during rotation. Vibration and wear will cause the clamping force between the two traction rollers with a fixed spacing to gradually decrease, eventually leading to the two traction rollers being unable to stably clamp the waste edge. This will result in the two traction rollers being unable to stably clamp the waste edge, thus preventing the waste edge from moving normally. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a waste edge traction mechanism that can stably clamp the waste edge and traction the waste edge to move, thus avoiding the problem of being unable to clamp the waste edge and therefore unable to traction the waste edge to move.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a waste edge traction mechanism, including a driving roller, a driven roller, a mounting base, a swing arm component and a driving component;

[0005] The mounting base is fixedly installed, one end of the swing arm component is rotatably connected to the mounting base, and the driven roller is rotatably connected to the other end of the swing arm component. The driven roller is used to drive the swing arm component to swing downward by gravity, thereby pressing the driven roller against the driving roller.

[0006] The drive component is connected to the drive roller and is used to drive the drive roller to rotate, thereby pulling the waste edge that passes between the drive roller and the driven roller to move.

[0007] Furthermore, the waste edge traction mechanism also includes a mounting column, the drive component is connected to the mounting column, and the drive roller is connected to the drive component so that the drive component drives the drive roller to rotate.

[0008] Furthermore, the mounting column is connected to a guide component for guiding the waste edge into the space between the drive roller and the driven roller.

[0009] Further, a specific structure of the guide component is provided, the guide component includes a connecting rod portion and a guide ring portion, the connecting rod portion is connected to the mounting column, the guide ring portion is connected to the connecting rod portion, the guide ring portion is provided with a notch, and the waste edge is used to pass through the guide ring portion and extend to the space between the driving roller and the driven roller.

[0010] Furthermore, the waste edge traction mechanism also includes a guide plate connected to the swing arm component and used to abut against the waste edge passing between the drive roller and the driven roller to guide the waste edge to be peeled off from the drive roller.

[0011] Further, a specific structure of the swing arm component is provided, the swing arm component including a swing rod and a roller shaft;

[0012] One end of the swing arm is rotatably connected to the mounting base;

[0013] The roller shaft is connected to the other end of the swing arm;

[0014] The driven roller is rotatably connected to the roller shaft and pressed against the driving roller by gravity.

[0015] Further, a specific structure of the guide plate is provided, the guide plate including a main body, a first connecting arm and a second connecting arm;

[0016] The main body is used to abut against the waste edge passing between the drive roller and the driven roller to guide the waste edge to peel off from the drive roller;

[0017] One end of the first connecting arm is connected to one end of the main board, and the other end of the first connecting arm is connected to the swing rod;

[0018] One end of the second connecting arm is connected to the other end of the main body, and the other end of the second connecting arm is connected to the roller.

[0019] Furthermore, a handle is connected to the swing arm component.

[0020] Furthermore, the waste edge traction mechanism also includes a cover assembly for covering the drive roller and the driven roller.

[0021] Further, a specific structure of the housing assembly is provided, the housing assembly including a fixed housing and a movable housing;

[0022] The fixed cover is fixedly installed;

[0023] The movable cover is rotatably connected to the fixed cover. During the rotation of the movable cover relative to the fixed cover, it has a closed position covering the driving roller and the driven roller, and an open position exposing the driving roller and the driven roller.

[0024] By employing the above technical solution, the waste edge cut from the side of the sheet passes between the drive roller and the driven roller. The driven roller, driven by gravity, swings its swing arm downwards, pressing the waste edge firmly against the drive roller. The drive component then rotates the drive roller, stably and efficiently traction the waste edge clamped by the drive and driven rollers, thus completing the waste edge traction operation. Furthermore, even with dimensional and assembly errors in the drive and driven rollers, and even with vibration and wear during operation, the driven roller can always swing its swing arm downwards by gravity, ensuring the waste edge is consistently and stably pressed against the drive roller. This guarantees consistent clamping and traction of the waste edge, avoiding the problem of being unable to move the waste edge due to insufficient clamping, and is applicable to traction of waste edges of varying thicknesses.

Detailed Implementation

[0032] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0033] like Figures 1-5 As shown, a waste edge traction mechanism includes a driving roller 1, a driven roller 2, a mounting base 3, a swing arm component 4, and a drive component 5;

[0034] The mounting base 3 is fixedly installed, one end of the swing arm component 4 is rotatably connected to the mounting base 3, and the driven roller 2 is rotatably connected to the other end of the swing arm component 4. The driven roller 2 is used to drive the swing arm component 4 to swing downward by gravity, thereby pressing the driven roller 2 against the driving roller 1.

[0035] The driving component 5 is connected to the driving roller 1 and is used to drive the driving roller 1 to rotate, thereby pulling the waste edge that passes between the driving roller 1 and the driven roller 2 to move.

[0036] Specifically, the waste edge cut from the side of the sheet passes between the drive roller 1 and the driven roller 2. The driven roller 2 can swing downwards with the swing arm component 4 under gravity, thus pressing the waste edge onto the drive roller 1 under gravity. Then, the drive component 5 can drive the drive roller 1 to rotate, thereby stably and efficiently pulling the waste edge clamped by the drive roller 1 and the driven roller 2, completing the waste edge traction work. Furthermore, even if there are dimensional processing errors and assembly errors in the drive roller 1 and the driven roller 2, and even if there is vibration and wear during operation, the driven roller 2 can always swing downwards with the swing arm component 4 under gravity, thus always stably pressing the waste edge onto the drive roller 1. This ensures that the waste edge is always clamped and pulled, avoiding the problem of not being able to pull the waste edge due to the inability to clamp it, and is also applicable to the traction of waste edges of different thicknesses.

[0037] like Figures 1-4 As shown, the waste edge traction mechanism may further include a mounting column 6, with the driving component 5 connected to the mounting column 6, and the drive roller 1 connected to the driving component 5 so that the driving component 5 drives the drive roller 1 to rotate. In this embodiment, the driving component 5 may be a geared motor connected to the mounting column 6, and the drive roller 1 may be connected to the output shaft hole of the geared motor so that the geared motor drives the drive roller 1 to rotate. The mounting base 3 is fixedly disposed on the housing of the geared motor. Of course, in some embodiments, the mounting base 3 may also be fixedly disposed on the mounting column 6.

[0038] like Figures 1-4As shown, a guide component for guiding waste edge into the space between the drive roller 1 and the driven roller 2 can be connected to the mounting column 6. The guide component, for example but not limited to, includes a connecting rod portion 7 and a guide ring portion 8. The connecting rod portion 7 is connected to the mounting column 6, and the guide ring portion 8 is connected to the connecting rod portion 7. The guide ring portion 8 has a notch 9, through which the waste edge passes and extends between the drive roller 1 and the driven roller 2. This design helps prevent the waste edge from deviating. In this embodiment, the connecting rod portion 7 is connected to the mounting column 6 via a bracket plate. One end of the drive roller 1 has a first flange 10 protruding radially outward, and the other end of the drive roller 1 has a second flange 11 protruding radially outward. The first flange 10 and the second flange 11 prevent the waste edge from slipping off the drive roller 1 during the traction process.

[0039] like Figures 1-5 As shown, the waste edge traction mechanism may further include a guide plate 12, which is connected to the swing arm component 4 and is used to abut against the waste edge passing between the drive roller 1 and the driven roller 2 to guide the waste edge to peel off from the drive roller 1, thereby preventing the ultra-thin and highly viscous waste edge from sticking to the drive roller 1 and thus wrapping around the drive roller 1, resulting in roller wrapping.

[0040] like Figures 1-5 As shown, the swing arm component 4 may include a swing rod 13 and a roller 14;

[0041] One end of the swing rod 13 is rotatably connected to the mounting base 3;

[0042] The roller shaft 14 is connected to the other end of the swing rod 13;

[0043] The driven roller 2 is rotatably connected to the roller shaft 14 and pressed against the driving roller 1 by gravity.

[0044] like Figures 1-5 As shown, the guide plate 12 may include a main body 15, a first connecting arm 16 and a second connecting arm 17;

[0045] The main body 15 is used to abut against the waste edge passing between the drive roller 1 and the driven roller 2 to guide the waste edge to peel off from the drive roller 1;

[0046] One end of the first connecting arm 16 is connected to one end of the main board 15, and the other end of the first connecting arm 16 is connected to the swing rod 13;

[0047] One end of the second connecting arm 17 is connected to the other end of the main board 15, and the other end of the second connecting arm 17 is connected to the roller 14.

[0048] like Figures 1-5 As shown, a handle 18 can be connected to the swing arm component 4; specifically, the handle 18 is connected to the swing rod 13 in the swing arm component 4. By lifting the handle 18, the entire swing arm component 4 can be driven to swing upward, thereby temporarily separating the driven roller 2 from the driving roller 1. After releasing the handle 18, the driven roller 2 can drive the swing arm component 4 to swing downward by gravity, thereby pressing the driven roller 2 against the driving roller 1, thereby ensuring that the driven roller 2 and the driving roller 1 clamp the waste edge.

[0049] like Figure 1 , 3 As shown in Figures 4 and 6, the waste edge traction mechanism may further include a cover assembly for covering the drive roller 1 and the driven roller 2; specifically, the cover assembly can effectively prevent damage caused by worker misoperation.

[0050] like Figure 1 , 3 As shown in Figures 4 and 6, the housing assembly may include a fixed housing 19 and a movable housing 20; wherein, the fixed housing 19 is fixedly disposed, and the movable housing 20 is rotatably connected to the fixed housing 19, and the movable housing 20 has a closed position covering the driving roller 1 and the driven roller 2 and an open position exposing the driving roller 1 and the driven roller 2 during the rotation relative to the fixed housing 19. Specifically, the movable cover 20 is rotated to the open position to expose the driving roller 1 and the driven roller 2. Then, the handle 18 is lifted to swing the entire swing arm component 4 upward, thereby temporarily separating the driven roller 2 from the driving roller 1. Then, the waste edge is passed between the driving roller 1 and the driven roller 2. Then, the handle 18 is released to allow the driven roller 2 to swing the swing arm component 4 downward by gravity, thereby pressing the driven roller 2 against the driving roller 1, thereby clamping the waste edge between the driven roller 2 and the driving roller 1. Then, the movable cover 20 is rotated to the closed position to cover the driving roller 1 and the driven roller 2. Then, the drive component 5 is activated to drive the driving roller 1 to rotate, thereby pulling the clamped waste edge to move.

[0051] In this embodiment, the movable cover 20 is rotatably connected to the fixed cover 19 via a hinge, and the fixed cover 19 is fixedly mounted on the housing of the geared motor. Of course, in some embodiments, the fixed cover 19 may also be fixedly mounted on the mounting column 6.

[0052] like Figure 6As shown, the waste edge traction mechanism of this application embodiment needs to be set in two in actual use, one for clamping and traction of the waste edge cut from the left side of the sheet, and the other for clamping and traction of the waste edge cut from the right side of the sheet.

[0053] In summary, the waste edge cut from the side of the sheet passes between the drive roller 1 and the driven roller 2. The driven roller 2, driven by gravity, swings the swing arm component 4 downwards, pressing the waste edge against the drive roller 1. Then, the drive component 5 drives the drive roller 1 to rotate, stably and efficiently pulling the waste edge clamped by the drive roller 1 and driven roller 2, thus completing the waste edge traction work. Furthermore, even if there are dimensional processing errors and assembly errors in the drive roller 1 and driven roller 2, and even if there is vibration and wear during operation, the driven roller 2 can always swing the swing arm component 4 downwards by gravity, ensuring that the waste edge is always stably pressed against the drive roller 1. This ensures that the waste edge is always clamped and pulled, avoiding the problem of not being able to pull the waste edge due to the inability to clamp it, and is also suitable for pulling waste edges of different thicknesses.

[0054] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
