[0035] The utility model provides a pressing roller device for a conveying platform. Figures 1 to 4 The utility model provides an embodiment of the pressing roller device of the conveying platform.

[0036] Please also read Figures 1 to 4 The pressing roller device of the conveying platform includes a frame 1, a conveying platform 2, a plurality of pressing roller mechanisms 4 and an adjusting component 3. The frame 1 is provided with a feeding station for storing unprocessed materials and a receiving station for storing processed materials. The conveying platform 2 is arranged between the feeding station and the receiving station on opposite sides, and is used to convey materials from the feeding station to the receiving station. The plurality of pressing roller mechanisms 4 are all arranged on the frame 1, and are used to limit the deviation of materials on the conveying platform 2. The pressing roller mechanism 4 includes a rubber-coated pressing roller 41, and the rubber-coated pressing roller 41 is located on the conveying platform 2, and the rubber-coated pressing roller 41 is used to press the materials on the conveying platform 2. The adjusting component 3 includes a tension spring 34, and the two ends are respectively connected to the frame 1 and the pressing roller mechanism 4.

[0037] When the feeding station stores unprocessed materials, a feeding device will be set to store the unprocessed materials. At the same time, the feeding device will transport the processed materials toward the conveying table 2, and transport them to the receiving station through the conveying table 2. The feeding station is provided with a receiving device for collecting the processed materials. The materials on the conveying table 2 are introduced into the receiving station through the receiving device and collected. The materials may be skewed in the process of conveying and collecting materials. When the materials are skewed, the material speed will be inconsistent with the conveying speed of the conveying table 2, which will reduce the synchronization accuracy between the materials and the conveying table 2, resulting in the pattern offset when the material is processed, and the pattern cannot be accurately processed. Therefore, a pressing roller mechanism 4 is set, and the rubber-coated pressing roller 41 on the pressing roller mechanism 4 is used to press the material on the conveying table 2, so that the material is difficult to offset during the transportation on the conveying table 2, thereby synchronizing the speed of the material and the conveying table 2, thereby improving the accuracy during processing.

[0038] The pressure of the rubber-coated pressure roller 41 pressing the material will be affected by the change of the material thickness. Different materials have different thicknesses. Therefore, the height of the rubber-coated pressure roller 41 relative to the conveying platform 2 needs to be adjusted so that the rubber-coated pressure roller 41 can press materials of any thickness. Therefore, an adjustment component 3 is provided. The adjustment component 3 changes the distance between the rubber-coated pressure roller 41 and the conveying platform 2 by adjusting the length of the tension spring 34. By changing the distance between the rubber-coated pressure roller 41 and the conveying platform 2, the rubber-coated pressure roller 41 can be suitable for materials of different thicknesses, so that the material can be pressed when the conveying platform 2 conveys materials of different thicknesses, ensuring that the speed of the material is synchronized with that of the conveying platform 2. At the same time, the tension spring 34 can also increase the pressure of the rubber-coated pressure roller 41 pressing the material, so that the rubber-coated pressure roller 41 can press the material more firmly. However, due to the elastic potential energy of the tension spring 34, the rubber-coated pressure roller 41 will not press too firmly, resulting in certain restrictions on material transportation, causing the material transportation speed to be lower than the speed of the conveying platform 2.

[0039] Therefore, in the technical solution provided by the utility model, multiple pressing roller mechanisms 4 are arranged on the frame 1 to limit the deviation of materials on the conveying platform 2. The pressing roller mechanism 4 includes a rubber-coated pressing roller 41, which is located on the conveying platform 2 and is used to press the materials on the conveying platform 2. The adjusting component 3 includes a tension spring 34, and its two ends are respectively connected to the frame 1 and the pressing roller mechanism 4, wherein the pressing roller mechanism 4 presses the material through the rubber-coated pressing roller 41, so that the material is difficult to deviate when being transported on the conveying platform 2, and at the same time cooperates with the tension spring 34 to adjust the pressure of the rubber-coated pressing roller 41 when pressing the material, so as to ensure that the material can be smoothly transported during the pressing process.

[0040] In order to enable the rubber-coated pressure roller 41 to press the material and release the pressure on the material, other structures need to cooperate. Specifically, in the embodiment of the utility model, the pressure roller mechanism 4 also includes a support rod 43 and a plurality of connecting plates 43. The support rod 43 is rotatably connected to the frame 1, and the plurality of connecting plates 43 are rotatably connected to the outer peripheral side of the support rod 43. The rubber-coated pressure roller 41 is rotatably connected to the plurality of connecting plates 43, and the connecting plate 43 is provided with the adjustment component 3 located on the side of the support rod 43 away from the rubber-coated pressure roller 41.

[0041] The position of the connecting plate 43 is limited by the support rod 43, and the connecting plate 43 drives the rubber-coated pressure roller 41 to rotate on the outer peripheral side of the support rod 43, so that the rubber-coated roller approaches or moves away from the material during the rotation, and cooperates with the adjustment component 3, so that when the material is transported on the conveying platform 2, the rubber-coated pressure roller 41 is pushed toward the conveying platform 2 to suppress the material. When new material needs to be replaced, the rubber-coated pressure roller 41 is pulled in the direction away from the conveying platform 2, so that new material can be placed on the conveying platform 2, thereby facilitating the staff to replace the material.

[0042] Furthermore, the plurality of connecting plates 43 are symmetrically arranged to stably support the two ends of the rubber-coated pressing roller 41 .

[0043] The connecting plates 43 are symmetrically arranged so that both ends of the rubber-coated pressure roller 41 are restricted by the connecting plates 43, so that the left and right ends of the rubber-coated pressure roller 41 will not shake randomly when pressing the material, and at the same time, the left and right ends of the rubber-coated pressure roller 41 are located on the same horizontal plane, so as to stably press the material on the conveying platform 2, avoiding the situation where one end of the rubber-coated pressure roller 41 presses on the material while the other end does not contact the material, resulting in uneven force on the material, and then offset and skew processing failure during the conveying process.

[0044] The strength of the rubber-coated pressure roller 41 in pressing the material is adjusted by adjusting the length of the tension spring 34. Adjusting the length of the tension spring 34 requires corresponding structural coordination. There are various types of structures that can adjust the length of the tension spring 34. Specifically, in an embodiment of the utility model, the adjustment assembly 3 also includes a fixed block 33, an adjustment block and a plurality of connecting members 35. The fixed block 32 is arranged on the frame 1. A threaded rod 31 is threadedly connected to the fixed block 32. The adjustment block 33 is rotatably connected to the threaded rod 31 so that when the threaded rod 31 is rotated, the adjustment block 33 is driven to move closer to or away from the fixed block 32. The plurality of connecting members 35 are respectively arranged on the adjustment block 33 and the connecting plate 43, and two adjacent connecting members 35 are respectively arranged at both ends of the tension spring 34. The connecting member 35 is located on the side of the support rod 43 away from the rubber-coated pressure roller 41.

[0045] The threaded rod 31 is rotated so that the threaded rod 31 drives the adjusting block 33 to move toward or away from the fixed block 32. When the adjusting block 33 moves, the tension spring 34 is pulled by the connecting piece 35 to move together. When the adjusting block 33 moves toward the fixed block 32, the end of the tension spring 34 close to the adjusting block 33 moves together, so that the tension spring 34 is stretched. The stretched tension spring 34 pulls the connecting plate 43 through elastic potential energy, so that the end of the connecting plate 43 without the rubber-coated pressure roller 41 moves toward the direction away from the conveying platform 2, thereby causing the end of the connecting plate 43 provided with the rubber-coated pressure roller 41 to move toward the conveying platform 2. At this time, the distance between the rubber-coated pressure roller 41 and the conveying platform 2 is The rubber-coated pressure roller 41 is reduced so that the rubber-coated pressure roller 41 can press materials with smaller thickness or press existing materials more firmly. When the adjusting block 33 moves in the direction away from the fixed block 32, the adjusting block 33 compresses the tension spring 34 through the connecting piece 35. After being compressed, the tension spring 34 pushes the end of the connecting plate 43 without the rubber-coated pressure roller 41 in the direction close to the conveying platform 2 through elastic potential energy, and makes the end of the connecting plate 43 with the rubber-coated pressure roller 41 move in the direction away from the conveying platform 2 to increase the distance between the rubber-coated pressure roller 41 and the conveying platform 2, so that the rubber-coated pressure roller 41 can press materials with larger thickness, and at the same time, the strength of the rubber-coated pressure roller 41 pressing the existing materials can be reduced.

[0046] Furthermore, a limiting block is arranged on the adjusting block 33 , and a limiting groove for sliding connection of the limiting block is opened on the frame 1 to limit the moving direction of the adjusting block 33 .

[0047] The adjusting block 33 may shake when it moves with the threaded rod 31. The shaking process will affect the rotation of the threaded rod 31 and will also cause the threaded rod 31 to constantly collide with the fixed block 32, accelerating the wear of the threaded rod 31. Therefore, it is necessary to limit the adjusting block 33. A limit groove is opened at the corresponding position of the frame 1, and a limit block is set on the adjusting block 33 so that the limit block slides in the limit groove. The limit block and the limit groove cooperate to limit the moving direction of the adjusting block 33, so that the adjusting block 33 can only move toward or away from the fixed block 32, so that the adjusting block 33 cannot shake at will.

[0048] The limit block can be set to a step shape or a T shape, so that the limit block is difficult to detach from the limit groove after being installed in the limit groove, further limiting the direction in which the adjustment block 33 can move, so that the adjustment block 33 cannot move toward or away from the connecting plate 43, and can only move toward or away from the fixed block 32.

[0049] Furthermore, the support rod 43 is located between the rubber-coated pressure roller 41 and the opposite side of the tension spring 34 to limit the position of the connection portion between the connecting plate 43 and the support rod 43 .

[0050] The support rod 43 is arranged between the rubber-coated pressure roller 41 and the opposite side of the tension spring 34, and combined with the connecting plate 43, a lever-like device can be formed, so that the staff can lift the rubber-coated pressure roller 41 or press down the rubber-coated pressure roller 41 with little effort. At the same time, the installation position of the connecting plate 43 is also restricted to prevent the installation position of the connecting plate 43 from being too far away from the conveying platform 2, resulting in the rubber-coated pressure roller being completely unable to contact the materials on the conveying platform 2.

[0051] The rotation of the support rod 43 and the rubber-coated roller needs to be carried out independently, that is, only the support rod 43 or the rubber-coated roller rotates during rotation. Therefore, it is necessary to set up multiple sets of bearings so that the support rod 43 and the rubber-coated roller will not drive other objects to rotate during rotation. Specifically, in the technical solution of the utility model, the connecting plate 43 is provided with a first bearing 44 for rotatably connecting the support rod 43, and the connecting plate 43 is provided with a second bearing 45 for rotatably connecting the rubber-coated pressure roller 41, and the frame 1 is provided with a third bearing 46 for rotatably connecting the support rod 43.

[0052] By setting the first bearing 44 and the third bearing 46, the support rod 43 will neither drive the connecting frame nor the frame 1 to rotate when rotating. The second bearing 45 will not cause the connecting plate 43 to rotate when the rubber-coated drum rotates. At the same time, a fourth bearing is also provided on the adjustment block 33 to cooperate with the threaded rod 31, so that the threaded rod 31 will not drive the adjustment to rotate when rotating, but will only drive the adjustment block 33 to move closer to or away from the fixed block 32.

[0053] The linear movement direction of the threaded rod 31 is restricted by the corresponding holes on the fixed block 32. The movement direction of the threaded rod 31 is restricted by the corresponding holes on the fixed block 32, and the movement direction of the adjusting block 33 is restricted by restricting the movement direction of the threaded rod 31. Specifically, in the technical solution of the present invention, a threaded hole for the threaded rod 31 to pass through is provided on the fixed block 32, and the threaded hole extends along the elongation direction of the tension spring 34. The threaded rod 31 is threadedly connected inside the threaded hole, and the movement direction of the threaded rod 31 is restricted by the extension direction of the threaded hole.

[0054] The length of the threaded rod 31 is limited, and the length of the contraction or extension of the tension spring 34 is also limited, so that the maximum spacing between the rubber-coated pressure roller 41 and the conveying platform 2 under the control of the adjustment component 3 is also limited. It is impossible to open a too large spacing to facilitate the staff to place new materials. Therefore, a structure that can continuously lift the rubber-coated pressure roller 41 is set. Specifically, in the technical solution of the utility model, the frame 1 is rotatably connected to a transmission shaft 6, and a plurality of cams 5 are arranged on the transmission shaft 6, and the plurality of cams 5 correspond to the plurality of connecting plates 43 one by one, so that when the cam 5 rotates, the end of the connecting plate 43 close to the tension spring 34 is pushed away from the transmission shaft 6.

[0055] The cam 5 is driven to rotate by rotating the rotating shaft. After rotating, the cam 5 gradually contacts the connecting plate 43, and after contacting the connecting plate 43, it pushes the end of the connecting plate 43 close to the tension spring 34 to move toward the direction close to the conveying platform 2, so that the end of the connecting plate 43 provided with the rubber-coated pressure roller 41 moves toward the direction away from the conveying platform 2, and the distance between the connecting plate 43 and the conveying platform 2 is enlarged, so as to facilitate the staff to place new materials on the conveying platform 2.

[0056] In order to facilitate the staff to rotate the transmission shaft 6, a handle can be set at one end of the transmission shaft 6, or a handle can be set at both ends of the transmission shaft 6, so that the staff can quickly access the handle to rotate the transmission shaft 6 when operating the equipment at any position.

[0057] Furthermore, the cam 5 is located on a side of the tension spring 34 facing the rubber-coated pressure roller 41 , and one end of the connecting plate 43 close to the tension spring 34 moves toward or away from the transmission shaft 6 to adjust the position of the rubber-coated pressure roller 41 .

[0058] The cam 5 is located between the tension spring 34 and the opposite side of the support rod 43, so that after the cam 5 rotates, it will only push the connecting plate 43 close to one end of the tension spring 34, thereby achieving the purpose of lifting the rubber-coated pressure roller 41. At the same time, by making the end of the connecting plate 43 close to the tension spring 34 move toward or away from the transmission shaft 6, the rubber-coated pressure roller 41 at the other end can move toward or away from the conveyor platform 2, thereby completing the pressing of the material on the conveyor platform 2, or facilitating the staff to place new materials on the conveyor platform 2.

[0059] What need to be manually operated by the staff are the threaded rod 31 and the transmission shaft 6. The length of the tension spring 34 is adjusted by rotating the threaded rod 31, thereby adjusting the force of the rubber-coated pressure roller 41 pressing the material. The rubber-coated pressure roller 41 is continuously lifted by rotating the transmission shaft 6, so that the rubber-coated pressure roller 41 is away from the conveying platform 2, which is convenient for the staff to place new materials, thereby greatly simplifying the operating steps of the staff and improving the convenience of manual operation.

[0060] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
