Description

Technical Field

[0001] This utility model relates to the technical field of conveyor belt production equipment, and specifically to a flattening device for conveyor belt processing. Background Technology

[0002] In the conveyor belt manufacturing process, vulcanization is a crucial step that determines product performance. High temperature and pressure cause the rubber compound to undergo a cross-linking reaction, forming a stable structure. However, during the cooling process after vulcanization, the conveyor belt is prone to defects such as surface wrinkles, localized bulges, or micro-bubbles due to uneven shrinkage of the rubber compound and the release of stress between the belt core and the rubber layer.

[0003] These defects not only affect the appearance quality of the conveyor belt but also weaken its structural integrity, leading to premature damage due to stress concentration during subsequent use, thus reducing the service life and operational safety of the conveyor belt. Therefore, low-temperature flattening treatment after vulcanization is a necessary process to ensure the quality of the finished conveyor belt.

[0004] Currently, most flattening equipment used in the industry adopts a fixed pressure roller structure, which makes it difficult to flexibly adjust the flattening height according to the thickness, material and actual flatness of the conveyor belt, resulting in unstable flattening effect. At the same time, the conveyor belt is prone to edge curling and local lifting during the flattening process. This deformation will cause uneven force on the conveyor belt when it enters the flattening roller, which may affect the flattening quality.

[0005] Therefore, the inventors believe that how to solve the above-mentioned technical problems is a technical problem that needs to be solved in the field of conveyor belt production equipment technology.

[0037] The internal threaded sleeve 172 is fixed inside the vertical adjustment plate 171; the internal threaded sleeve 172 is threadedly connected to the screw 153;

[0038] The flattening roller 140 spans across the conveyor belt 120 and is rotatably connected to the outside of the vertical adjustment plate 171 via a roller shaft;

[0039] The motor 180 is fixed on the outside of the vertical adjustment plate 171, and the main shaft of the motor 180 is connected to the roller shaft of the flattening roller 140.

[0040] It should be noted that the material of the conveyor belt 120 should be more heat-resistant than that of the conveyor belt in the flattening stage. PTFE coated conveyor belts or fluororubber conveyor belts are preferred, as they have the best performance in terms of temperature resistance, non-stickiness and strength, and can fully meet the conveying requirements of the low-temperature flattening stage.

[0041] In this embodiment, both ends of the positioning roller 130 are fixed to the frames 121 on both sides of the conveyor belt 120 by fixing plates 160;

[0042] The fixed plate 160 includes a vertical plate 162 and a horizontal plate 161 integrally formed with the vertical plate 162; the vertical plate 162 is fixed on the frame 121 of the conveyor belt 120;

[0043] A bolt 171 passes through the roller shaft of the positioning pressure roller 130, and the tail of the bolt 171 passes vertically through the transverse plate 161; a spring 172 is sleeved on the tail of the bolt 171 below the transverse plate 161, and a nut 173 is connected to the tail of the bolt 171; adaptive pressure is achieved through the elastic compression of the spring 172.

[0045] In this embodiment, positioning pressure rollers 130 are provided at both the front and rear of the flattening roller 140; a rotating handle 154 is fixed to the top of the screw 153.

[0046] The method of using the flattening device for conveyor belt processing provided in this embodiment of the utility model is as follows:

[0047] (1) Pre-treatment adjustment: According to the thickness of the conveyor belt to be flattened, adjust the overall height of the positioning roller 130 through the waist hole 163 on the vertical plate 162: rotate the top of the screw 153 and rotate the handle 154 to drive the vertical adjustment plate 171 to move up and down, thereby adjusting the height of the flattening roller 140 so that the flattening roller 140 contacts the surface of the conveyor belt and applies appropriate pressure.

[0048] (2) Start-up: Start the motor 180 and the conveyor belt 120, so that the flattening roller 140 rotates with the motor drive, and the rotation direction is consistent with the conveying direction of the conveyor belt 120, so as to ensure that the linear speeds of the two are matched.

[0049] (3) Flattening treatment: Place one end of the conveyor belt, which is in the low temperature stage after vulcanization, on the conveyor belt 120, and the conveyor belt is conveyed forward with the conveyor belt 120;

[0050] First, it passes through the positioning pressure roller 130 in front of the flattening roller 140, where the raised edges and uneven parts are pre-pressed to form a smooth conveying posture.

[0051] When it enters below the flattening roller 140, the surface wrinkles, protrusions and tiny air bubbles are compacted and smoothed under the rotational pressure of the flattening roller 140.

[0052] The flattened conveyor belt continues to move forward, and after passing the flattening roller 140, the positioning roller 130 behind it stops again to ensure that the flatness is maintained stably after flattening.

[0053] (4) Stop and reset: After all conveyor belts are flattened, first turn off the conveyor belt 120, then turn off the motor 180; rotate the handle 154 to raise the flattening roller 140 to reset, and complete the operation.
