Description

Technical Field

[0001] The utility model relates to the field of coating machines, in particular to a traction rubber roller assembly. Background Art

[0002] The structure used in the traction assembly of the coating machine on the market is generally that the traction rubber roller (one cylinder on each side provides thrust) is pressed on the pole piece or foil, the traction steel roller holds the pole piece or foil, and the traction steel roller rotates to drive the pole piece or foil forward. The traction rubber roller is a two-layer structure, the outer layer is made of rubber material, and the inner layer is made of metal material. When the rubber roller is working, due to the thrust of the cylinders on both sides, the metal axis inside it will bend and deform to a certain extent. This mechanism has the following disadvantages:

[0003] The degree of compression of the pole piece by the traction rubber roller in the length direction is inconsistent: due to the bending deformation of the traction rubber roller axis to a certain extent, the degree of compression of the outer rubber layer will be different, resulting in loose compression in the middle and tight compression at both ends. This situation will cause uneven force on the pole piece, resulting in wrinkling or slipping of the pole piece. The larger the width of the pole piece, the more obvious this inconsistent tension is.

[0004] Wear of traction rubber roller: Due to uneven force, the degree of wear of the traction rubber roller in the length direction will be inconsistent, which shortens the grinding cycle of the traction rubber roller and thus affects the service life of the traction rubber roller.

[0005] Inconvenient to adjust: only the pressure on both sides of the traction rubber roller can be adjusted, and the middle pressure cannot be controlled.

[0006] If the bending deformation of the axis is reduced by increasing the size of the traction rubber roller, the weight of the traction rubber roller will increase, which will be inconvenient for transportation, installation and disassembly. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a traction rubber roller assembly, which can apply thrust in the middle of the traction rubber roller, reduce the deformation degree of the traction rubber roller, improve the force uniformity of the pole piece, and reduce the occurrence of wrinkling and slipping of the pole piece or foil.

[0008] In order to solve the above problems, a traction rubber roller assembly is adopted, which comprises:

[0009] A traction steel roller, both ends of which are mounted on the frame;

[0010] The first cylinders are mounted in pairs on the frame and spaced apart from the traction steel rollers, with their telescopic ends facing the traction steel rollers;

[0011] The traction rubber roller has two ends which are respectively arranged on the telescopic ends of the first cylinder and pressed against the traction steel roller;

[0012] A mounting plate, both ends of which are mounted on the frame and are spaced apart from the traction rubber roller;

[0013] A cylinder connecting plate, which is mounted on the mounting plate;

[0014] A second cylinder is mounted on the cylinder connecting plate, with its telescopic end facing the traction rubber roller;

[0015] a bracket mounted on the telescopic end of the second cylinder;

[0016] The two ends of the small pressure roller are installed on the bracket and pressed tightly on the traction rubber roller.

[0017] With such a structure, the thrust applied by the small pressure roller to the traction rubber roller can be adjusted by the second cylinder, thereby reducing the degree of bending deformation of the axis of the traction rubber roller.

[0018] As a further improvement of the utility model, a T-slot is provided on the mounting plate, a T-nut with a sliding fit is built into the T-slot, holes are provided on the cylinder connecting plate for bolts to pass through, the bolts are threadedly connected to the T-nut and tightened on the cylinder connecting plate.

[0019] With this structure, the cylinder connecting plate can be moved left and right and then tightened by bolts.

[0020] As a further improvement of the utility model, a vertical rotating shaft is rotatably connected to the cylinder connecting plate, and the second cylinder is fixedly sleeved on the rotating shaft.

[0021] As a further improvement of the utility model, a cylinder limiting shaft and a cylinder limiting block are provided on the second cylinder. The cylinder limiting block is fixedly sleeved on the cylinder limiting shaft. The cylinder limiting shaft passes through the part of the second cylinder spaced apart from the piston in a threaded connection manner and abuts against the back of the bracket.

[0022] With such a structure, after the cylinder limit shaft abuts against the bracket, the bracket can be prevented from retreating, so as to stabilize the pressure.

[0023] As a further improvement of the utility model, a cylinder rotation angle adjustment limit mechanism is arranged on the cylinder connecting plate, and the cylinder rotation angle adjustment limit mechanism includes a support, a nut and a screw. The support is arranged on the cylinder connecting plate and is located on both sides of the second cylinder and is spaced apart from the second cylinder. A nut is fixedly connected to the support, and the screw slides through the support threaded connection nut to abut the second cylinder.

[0024] With such a structure, when the second cylinder rotates, the screw can be used to abut the second cylinder to limit the angle after rotation. The rotation of the second cylinder can change the force application area, making the pressure area smaller and the pressure greater, so as to further adjust the local deformation of the traction rubber roller.

[0025] The utility model adds an intermediate cylinder and a small pressure roller, which can apply thrust in the middle of the traction rubber roller, reduce the deformation degree of the traction rubber roller, improve the force uniformity of the pole piece, and reduce the occurrence of wrinkling and slipping of the pole piece or foil.

[0026] The utility model can achieve the purpose of reducing the deformation of the rubber roller without additionally increasing the size and weight of the traction rubber roller.

[0027] After the utility model adds the middle small pressure roller, the adjustment of the traction rubber roller is more convenient, and multiple force points can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A traction steel roller 1, both ends of which are mounted on a frame 11;

[0036] The first cylinders 3 are mounted in pairs on the frame 11 and spaced apart from the traction steel roller 1, with their telescopic ends facing the traction steel roller 1;

[0037] The traction rubber roller 2 has two ends respectively arranged on the telescopic ends of the first cylinder 3 and pressed against the traction steel roller 1;

[0038] The mounting plate 4 has two ends mounted on the frame 11 and is spaced apart from the traction rubber roller 2;

[0039] A cylinder connecting plate 5, which is mounted on the mounting plate 4;

[0040] A second cylinder 6, which is mounted on the cylinder connecting plate 5, with its telescopic end facing the traction rubber roller 2;

[0041] A bracket 7 mounted on the telescopic end 6 of the second cylinder;

[0042] The small pressure roller 12 has two ends mounted on the bracket 7 and is pressed tightly against the traction rubber roller 2 .

[0043] With such a structure, the thrust applied by the small pressure roller 12 to the traction rubber roller 2 can be adjusted by the second cylinder 6, thereby reducing the degree of bending deformation of the axis of the traction rubber roller 2.

[0044] In this embodiment, a T-slot 41 is provided on the mounting plate 4, a slidingly adapted T-nut 8 is built into the T-slot 41, holes are provided on the cylinder connecting plate 5 for bolts 9 to pass through, the bolts 9 are threadedly connected to the T-nut 8 and tightened on the cylinder connecting plate 5.

[0045] With such a structure, the cylinder connecting plate 5 can be moved left and right and then tightened by the bolts 9 .

[0046] In this embodiment, a vertical rotating shaft 10 is rotatably connected to the cylinder connecting plate 5 , and the second cylinder 6 is fixedly sleeved on the rotating shaft 10 .

[0047] With such a structure, after the cylinder limiting shaft 16 abuts against the second cylinder 6 applying force, the bracket 7 can be prevented from retreating, so as to stabilize the pressure.

[0048] In this embodiment, a cylinder limiting shaft 16 and a cylinder limiting block 17 are provided on the second cylinder 6. The cylinder limiting block 17 is fixedly sleeved on the cylinder limiting shaft 16. The cylinder limiting shaft 16 passes through the portion of the second cylinder 6 spaced apart from the piston in a threaded manner and abuts against the back of the bracket 7.

[0049] With such a structure, after the cylinder limiting shaft 16 abuts against the bracket 7, the bracket 7 can be prevented from retreating, so as to stabilize the pressure.

[0050] As a further improvement of the utility model, a cylinder rotation angle adjustment limit mechanism is provided on the cylinder connecting plate 5, and the cylinder rotation angle adjustment limit mechanism includes a support 14, a nut 15 and a screw 13.

The number of small pressure rollers 12 can be freely selected according to the length of the traction rubber roller 2 and the effect to be achieved.

[0053] The utility model reduces the deformation degree of the axis of the traction rubber roller by adding a small pressure roller behind the traction rubber roller, thereby improving the force uniformity of the traction rubber roller. The lateral installation position of the small pressure roller can be freely adjusted (the installation position of the small pressure roller can be freely selected according to the clamping effect during the debugging process), and the angle can be adjusted adaptively (to make the contact between the small pressure roller and the traction rubber roller better and the force more uniform). The specific implementation is the preferred implementation of the utility model, and other principles and basic structures that are the same or similar to those of this embodiment are within the protection scope of the utility model.

For technicians in the technical field to which the present invention belongs, several equivalent substitutions or obvious variations can be made without departing from the concept of the present invention, and the performance or use is the same, which should be regarded as belonging to the protection scope of the present invention.
