Description

Technical Field

[0001] The present invention relates to the technical field of roller rubber coating, in particular to an automatic pressing device for roller rubber coating. Background Art

[0002] Roller lagging can effectively increase the friction of the roller surface and prevent the conveyor belt from slipping. Currently, the most common method of roller lagging is to adhere cut film sheets to the roller surface with an adhesive. In this process, the positioning and pressing of the film sheets are key to ensuring the quality of the lagging.

[0003] During the drum lagging process, when the film is delivered to the drive roller and begins to wrap around the drum, the end of the film often falls off. This not only affects the continuity and efficiency of the lagging, but also leads to unstable lagging quality, increases the cost of subsequent rework and repair, and has limitations.

[0004] The reason for this problem is that, on the one hand, the cross roller only constrains the film in the horizontal direction when positioning it, and cannot provide effective fixation and support for the ends of the film. When the drum rotates to wrap the film, the ends of the film lack sufficient restraint and are easily separated from the drum surface due to external forces such as centrifugal force. On the other hand, the existing adhesion device cannot fully ensure the tight fit between the ends of the film and the drum, making the ends of the film easily loose and fall off during the wrapping process. Therefore, we have proposed an automatic compression device for roller wrapping to solve this problem. Summary of the Invention

[0045] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0046] An embodiment of the present invention discloses an automatic pressing device for roller rubber lagging.

[0047] Example 1: The present invention discloses an automatic pressing device for roller rubber lagging. Figure 1-3 As shown, it includes a body 1, a driving roller 2 for driving the drum to rotate is provided on the body 1, and a rubber lagging pressing and anti-slipping unit 3 is provided on the body 1. The rubber lagging pressing and anti-slipping unit 3 includes a roller conveyor 31, a glue spraying part 32, an anti-slipping part 33, an adjustable pressing part 34 and an arc-shaped guide block 38;

[0048] A roller conveyor 31 is arranged at one end of the machine body 1, and is used to convey the cut rubber to the bottom of the transmission roller 2; a glue spraying part 32 is arranged on one side of the roller conveyor 31, and is used to spray adhesive on the rubber; an anti-slip part 33 is arranged at one end of the transmission roller 2, and is used to press the end of the rubber and rotate 180° synchronously with the transmission roller 2 to prevent the end of the rubber from detaching from the transmission roller 2; an adjustable pressing part 34 is arranged at one end of the roller conveyor 31, and is used to press the rubber adhered to the roller; an arc guide block 38 is arranged below the transmission roller 2, and is used to convey the rubber and adhere it to the roller.

[0049] The adjustable pressing member 34 includes a column 341, a positioning block 342, a first clamping block 343, a single-rod cylinder 344 and a second clamping block 345; the column 341 is fixedly assembled at one end of the body 1; the positioning block 342 is slidably connected to the inside of the column 341; the first clamping block 343 is fixedly assembled to the inside of the positioning block 342; the single-rod cylinder 344 is arranged inside the first clamping block 343, and the single-rod cylinder 344 is rotatably connected to the first clamping block 343; the second clamping block 345 is arranged at one end of the positioning block 342, and the adjustable pressing member 34 also includes a support rod 346, a pressure roller 347, a third clamping block 348, an anti-slip block 349 and a second Push-pull cylinder 350; one end of the support rod 346 is rotatably connected to the inside of the second block 345; the pressure roller 347 is arranged at one end of the support rod 346, and the pressure roller 347 is against the rubber; the third block 348 is arranged on the support rod 346, and the third block 348 is rotatably connected to the single-rod cylinder 344; the anti-slip block 349 is fixedly assembled on both sides of the positioning block 342, and the anti-slip block 349 is slidably connected to the inside of the column 341; the second push-pull cylinder 350 is arranged below the positioning block 342, the second push-pull cylinder 350 is fixedly assembled with the column 341, and the output shaft of the second push-pull cylinder 350 is fixedly assembled with the positioning block 342.

[0050] In this embodiment, the rollers used in industrial production come in a variety of sizes and diameters. When rubberizing rollers of varying diameters, if the height of the pressure element is fixed, the pressure roller 347 may not be able to maintain good contact with the rubber on the roller surface. For example, for rollers with larger diameters, if the height of the pressure element is insufficient, the pressure roller 347 will be at a considerable distance from the roller surface, making it difficult to apply sufficient pressure to the rubber. For rollers with smaller diameters, if the height of the pressure element is too high, the pressure roller 347 may overpress the roller, damaging the rubber or the roller. Adjusting the height of the positioning block 342 using the second push-pull cylinder 350 ensures that the pressure roller 347 is always in the proper position, closely fitting the rubber on the surfaces of rollers of varying diameters and ensuring a satisfactory compression effect.
