Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to an anti-oil-piling forward and reverse roller coating machine. Background Technology

[0002] Ordinary double-roller coating machines have coating rollers that rotate in the same direction. In the application of paint to boards, it is difficult for paints to meet the requirements of fullness, smoothness and gloss. Fullness may need to be achieved by repeated coatings, but smoothness and gloss are difficult to achieve. Therefore, a reverse-rotating roller coating machine that prevents oil buildup is used to coat materials multiple times.

[0003] Existing technologies, such as the utility model patent with publication number CN216631380U, disclose an anti-oil-piling forward and reverse roller coating machine. This patent uses a conveyor belt connected at both ends by a frame, and a first coating roller and a second coating roller disposed above and separated from each other on the conveyor belt. The upper surface of the conveyor belt is in close contact with the lower surface of the material, and the material is conveyed horizontally from the loading end to the unloading end. Lifting plates are connected to both sides of the frame via guide rail assemblies, and a connecting seat is connected to the other side of the lifting plate. A cylinder assembly is connected to the bottom of the connecting seat, and a first bearing seat on one side connects the first coating roller to the second coating roller. The two coating rollers are rotatably connected. The first coating roller and the second coating roller rotate in opposite directions during operation. When the first coating roller and the second coating roller encounter an upward force, the cylinder rod of the cylinder assembly is lifted. This utility model equipment solves the problem that the existing product has a good paint fullness on the surface, but the product needs to be measured multiple times when encountering different board thicknesses. If the board is too tall, it will exert downward pressure on the board when passing through the coating roller, causing damage to the board or the conveyor belt. In severe cases, it may also cause collision between the board and the coating roller. When the conveyor belt needs to be repaired or replaced, the entire equipment needs to be moved by forklift, which is time-consuming and labor-intensive.

[0004] In daily operation, during the coating process of the equipment, unevenness is easily created on the surface of the material plate, causing coating to accumulate and resulting in defective products. Utility Model Content

[0005] The purpose of this invention is to solve the problem of uneven coating on material plates in the existing technology, and to propose an anti-oil-piling forward and reverse roller coating machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-oil-piling forward and reverse roller coating machine, comprising a frame, a conveyor belt, a connecting frame, rollers, a paint box, and a leveling device. The conveyor belt is arranged inside the frame, the connecting frame is arranged on the surface of the frame, rollers are arranged inside the connecting frame, and a paint box is arranged inside the connecting frame. The paint box is positioned above the rollers. The leveling device is arranged on the surface of the frame, comprising a scraper and a connecting plate. The connecting plate is fixedly connected to the upper surface of the frame, and the connected scraper is positioned above the conveyor belt. A connecting rod is fixedly connected to the side of the scraper, and the connecting rod is slidably connected to the interior of the connecting plate. A slider is fixedly connected to one end of the connecting rod. A groove is formed on the surface of the connecting plate, and the slider is slidably connected to the inner wall of the groove. An adjusting groove is formed on the inner wall of the groove. A recess is formed inside the slider, and a retaining ball is slidably connected inside the recess. A stop block is fixedly connected to one end of the retaining ball, and one end of the retaining ball is positioned against the inner wall of the adjusting groove. A first spring is fixedly connected to the surface of the retaining ball.

[0007] Furthermore, the surface of the slider is provided with a groove, and a sliding rod is slidably connected to the inner wall of the groove. By setting the slider, the connecting rod can be moved, reducing the situation where the scraper is difficult to move during use.

[0008] Furthermore, a stop rod is fixedly connected to one end of the slide rod, and one end of the stop rod abuts against the surface of the stop block. The stop rod is provided to facilitate limiting the position of the stop block.

[0009] Furthermore, a second spring is fixedly connected to one end of the slide rod, and the end of the second spring away from the slide rod is fixedly connected to the inner wall of the groove. The second spring is provided to facilitate the application of a restoring force to the connecting rod.

[0010] Furthermore, a cleaning device is provided on the side of the frame. The cleaning device includes a connecting block and a cleaning plate. The connecting block is fixedly connected to one end of the frame. The cleaning plate is disposed inside the connecting block. A slot is opened at one end of the cleaning plate. A connecting groove is opened on the surface of the connecting block. A positioning rod is fixedly connected inside the connecting groove. By setting the cleaning plate, the surface of the conveyor belt can be cleaned, reducing the situation where the surface of the conveyor belt easily absorbs paint and causes material plate contamination during equipment use.

[0011] Furthermore, a pull plate is sleeved on the surface of the positioning rod, and the pull plate is slidably connected to the inside of the connecting groove. The positioning rod is provided to facilitate the limited movement of the pull plate.

[0012] Furthermore, a locking block is fixedly connected to one end of the pull plate, and the locking block engages with the inner wall of the slot. The locking block is provided to facilitate the limiting of the cleaning plate.

[0013] Furthermore, a third spring is sleeved and connected to the surface of the positioning rod. The two ends of the third spring are fixedly connected to the surface of the pull plate and the inner wall of the connecting groove, respectively. The third spring is provided to facilitate the application of a restoring force to the pull plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the equipment is in use, the user places the material plate to be coated on the surface of the conveyor belt, then starts the equipment. The rollers rotate, immersing the coating in the coating box onto the roller surface, and then the material is coated by rolling. When the equipment is in use, the user pulls the abutment rod. When the abutment rod moves, it drives the connecting rod to move. Then the connecting rod moves and causes the second spring to deform, generating elastic force. Then the abutment rod disengages from the surface of the abutment block, and the first spring is released from its restraint. Then the sliding slider drives the ball to move out of the adjustment groove. Then the sliding slider moves and causes the connecting rod to move to adjust the scraper. By setting up a scraping device, the coating on the surface of the material plate is effectively leveled, which plays a role in cleaning the excess coating on the surface of the material plate. This reduces the possibility of unevenness on the surface of the material plate during equipment use, causing coating to accumulate and resulting in defective products, thus improving the practicality of the equipment.

[0016] 2. In this utility model, by setting up a cleaning device, when the equipment is in use, the user pulls the pull plate. When the pull plate slides on the surface of the positioning rod under force, it drives the third spring to displace and deform, generating elastic force. Then, the pull plate moves, causing the locking block to move and disengage from the inside of the locking groove. Subsequently, the cleaning plate is unrestrained. By setting up a cleaning device, the surface of the conveyor belt is effectively cleaned, which plays a role in cleaning the paint adhering to the surface of the conveyor belt. This reduces the likelihood of paint dripping onto the surface of the conveyor belt during equipment use, which would contaminate the surface of the conveyor belt and cause contamination when materials are placed on the surface of the conveyor belt during secondary use. This improves the practicality of the equipment. Attached Figure Description

[0028] Specifically, the surface of the slider 64 is provided with a groove 611, and the inner wall of the groove 611 is slidably connected to a slide rod 613.

[0029] In this embodiment, by setting the slider 64, the connecting rod 63 can be moved, reducing the difficulty of moving the scraper 61 when the equipment is in use.

[0030] Specifically, one end of the slide bar 613 is fixedly connected to a stop bar 612, and one end of the stop bar 612 abuts against the surface of the stop block 610. The stop bar 612 is provided to facilitate the limiting of the stop block 610.

[0031] Specifically, a second spring 614 is fixedly connected to one end of the slide rod 613. The end of the second spring 614 away from the slide rod 613 is fixedly connected to the inner wall of the pull groove 611. The second spring 614 is provided to facilitate the application of a restoring elastic force to the connecting rod 63.

[0032] Example 2;

[0033] In this embodiment: a cleaning device 7 is provided on the side of the frame 1. The cleaning device 7 includes a connecting block 72 and a cleaning plate 71. The connecting block 72 is fixedly connected to one end of the frame 1. The cleaning plate 71 is disposed inside the connecting block 72. A slot 73 is provided at one end of the cleaning plate 71. A connecting groove 74 is provided on the surface of the connecting block 72. A positioning rod 75 is fixedly connected inside the connecting groove 74.

[0034] In this embodiment: by setting up the cleaning plate 71, the surface of the conveyor belt 2 can be cleaned, reducing the situation where the surface of the conveyor belt 2 easily absorbs paint and causes material plate contamination during equipment use.

[0035] Specifically, a pull plate 76 is sleeved and connected to the surface of the positioning rod 75. The pull plate 76 is slidably connected to the inside of the connecting groove 74. The positioning rod 75 is provided to facilitate the limited movement of the pull plate 76.

[0036] Specifically, a locking block 77 is fixedly connected to one end of the pull plate 76. The locking block 77 engages with the inner wall of the slot 73. The locking block 77 is provided to limit the movement of the cleaning plate 71.

[0037] Specifically, a third spring 78 is sleeved and connected to the surface of the positioning rod 75.

The third spring 78 is provided to facilitate the application of a restoring force to the pull plate 76.

[0038] Working Principle: When using the equipment, the user places the material plate to be coated on the surface of the conveyor belt 2, then starts the equipment. The roller 4 rotates, immersing the coating from the coating box 5 onto its surface. The material is then coated by rolling the coating. During operation, the user pulls the abutment rod 612. When the abutment rod 612 moves, it moves the connecting rod 63. The connecting rod 63 then causes the second spring 614 to deform, generating elasticity. The abutment rod 612 then disengages from the surface of the abutment block 610, and the first spring 69 loses its restraint. The sliding slider 64 then moves the retaining ball 68, disengaging it from the adjusting groove 66. The sliding slider 64 then moves the connecting rod 63, adjusting the scraper 61. By setting up the leveling device 6, the coating on the surface of the material plate is effectively leveled, cleaning excess coating and reducing the risk of unevenness and coating buildup, which can lead to defective products. This improves the equipment's practicality.

[0039] When the equipment is in use, the pull plate 76 is pulled. When the pull plate 76 slides on the surface of the positioning rod 75 under force, it drives the third spring 78 to displace and deform, generating elastic force. Then the pull plate 76 moves, causing the locking block 77 to move and disengage from the inside of the locking groove 73. Then the cleaning plate 71 is unrestrained. By setting up the cleaning device 7, the surface of the conveyor belt 2 is effectively cleaned, which plays a role in cleaning the paint adhering to the surface of the conveyor belt 2. This reduces the possibility of paint dripping onto the surface of the conveyor belt 2 during the use of the equipment, which would contaminate the surface of the conveyor belt 2 and cause contamination when materials are placed on the surface of the conveyor belt 2 during secondary use. This improves the practicality of the equipment.
