Description

Technical Field

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

[0002] Roller rubber coating can effectively increase the friction of the roller surface and prevent the conveyor belt from slipping. At present, the common roller rubber coating method is to stick the cut film on the roller surface through an adhesive. In this process, the positioning and pressing of the film are the key links to ensure the quality of the rubber coating.

[0003] During the drum lagging process, when the film is delivered to the transmission roller and begins to wrap 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, when the horizontal roller is positioning the film, it can only constrain the film in the horizontal direction, and cannot provide effective fixation and support for the end of the film. When the roller rotates to drive the film to wrap, the end of the film is easy to break away from the surface of the roller due to the lack of sufficient binding force under the action of external forces such as centrifugal force; on the other hand, the existing adhesion device cannot fully ensure the close fit between the end of the film and the roller, making the end of the film easy to loosen and fall off during the rubber coating process. Therefore, we propose an automatic pressing device for roller rubber coating to solve the above problems. Summary of the invention

[0025] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0026] Embodiments of the present invention disclose an automatic pressing device for drum rubber coating.

[0027] Embodiment 1. Embodiments of the present invention disclose an automatic pressing device for drum rubber coating. As shown in the attached Figures 1-3 figure, it includes a machine body 1. A driving roller 2 for driving the drum to rotate is provided on the machine body 1. A rubber coating pressing and anti - detachment unit 3 is provided on the machine body 1. The rubber coating pressing and anti - detachment unit 3 includes a roller conveyor 31, a glue spraying member 32, an anti - detachment member 33, an adjustable pressing member 34, and an arc - shaped guiding block 38. The roller conveyor 31 is arranged at one end of the machine body 1 and is used to transport the cut rubber sheet to the lower part of the driving roller 2. The glue spraying member 32 is arranged on one side of the roller conveyor 31 and is used to spray adhesive on the rubber sheet. The anti - detachment member 33 is arranged at one end of the driving roller 2 and is used to press the end of the rubber sheet and rotate synchronously with the driving roller 2 by 180° to prevent the end of the rubber sheet from detaching from the driving roller 2. The adjustable pressing member 34 is arranged at one end of the roller conveyor 31 and is used to press the rubber sheet adhered to the drum. The arc - shaped guiding block 38 is arranged under the driving roller 2 and is used to transport and adhere the rubber sheet to the drum.

[0028] 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 machine body 1; the positioning block 342 is slidably connected inside the column 341; the first clamping block 343 is fixedly assembled inside 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 further includes a support rod 346, a pressure roller 347, a third clamping block 348, an anti-disengagement block 349, and a second push-pull cylinder 350; one end of the support rod 346 is rotatably connected inside the second clamping block 345; the pressure roller 347 is arranged at one end of the support rod 346, and the pressure roller 347 abuts against the rubber sheet; the third clamping block 348 is arranged on the support rod 346, and the third clamping block 348 is rotatably connected to the single-rod cylinder 344; the anti-disengagement blocks 349 are fixedly assembled on both sides of the positioning block 342, and the anti-disengagement blocks 349 are slidably connected inside 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.

[0029] In this embodiment, the drum specifications used in industrial production are diverse, and the diameters are different. When performing rubber coating operations on drums with different diameters, if the height of the pressing member is fixed, there may be a situation where the pressure roller 347 cannot be in good contact with the rubber sheet on the drum surface. For example, for a drum with a larger diameter, if the height of the pressing member is insufficient, there will be a large distance between the pressure roller 347 and the drum surface, making it difficult to apply sufficient pressure to the rubber sheet; while for a drum with a smaller diameter, if the height of the pressing member is too high, the pressure roller 347 may be pressed down excessively, damaging the rubber sheet or the drum. By adjusting the height of the positioning block 342 through the second push-pull cylinder 350, the pressure roller 347 can always be in a proper position, closely fitting the rubber sheet on the surfaces of drums with different diameters, ensuring the pressing effect.
