Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and more specifically to a belt conveyor coating machine. Background Technology

[0002] Belt conveyor coating machines are automated equipment that integrates belt conveyor systems and coating processes. Their core function is to continuously and stably transport the workpiece to be processed to the coating area using a belt, thereby completing the uniform application of coatings such as adhesives, inks, and paints. This equipment is widely used in industries such as packaging, printing, electronics, and leather. Essentially, it integrates the conveying and coating processes through automation to improve production efficiency and coating accuracy.

[0003] During the process of coating materials onto the conveyor belt, the coating will come into contact with the workpiece in the form of spray, drip, or high-speed jet. Due to factors such as workpiece edge rebound, air pressure disturbance, or equipment vibration, some coating will detach from the target area and adhere to the belt surface. After the coating on the belt surface accumulates, it may be transferred during subsequent workpiece transport, causing contamination of the back of the workpiece or uncoated areas, resulting in defective products. Moreover, if the coating dries and forms a hard lump, it can easily scratch the workpiece surface during later cleaning. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a belt conveyor coating machine to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a belt conveyor coating machine, comprising a belt conveyor and a coating machine body mounted on the belt conveyor, wherein limit bars are fixedly connected at equal intervals to the bottom of the belt conveyor, and a sliding seat is longitudinally slidably connected to the outer surface of the limit bars, and bolts are rotatably connected to the bottom of the belt conveyor through bearings, the outer surface of the bolts being threadedly connected to the inside of the sliding seat, a liquid storage tank and a placement tank are provided on the surface of the sliding seat, a cleaning component is installed inside the liquid storage tank, and a cotton cloth is placed inside the placement tank, and a drive motor is fixedly mounted on the outer surface of the sliding seat, the output end of the drive motor being fixedly connected to the input end of the cleaning component.

[0006] Furthermore, the cleaning assembly includes a connecting shaft rotatably connected to both sides of the liquid storage tank via bearings. A rotating plate is rotatably connected to the surface of the connecting shaft. A limiting post is fixedly connected to the end face of the rotating plate away from the connecting shaft. A limiting plate is slidably connected inside the limiting post. A connecting rod is fixedly connected to the center of the surface of the limiting plate. A limiting plate is fixedly connected to the surface of the limiting plate. The limiting plate is movably installed inside the limiting post. A stop plate is fixedly connected to the end of the connecting rod away from the limiting plate. A rotating cylinder is slidably connected to the outer surface of the stop plate. A positioning groove matching the connecting rod is opened inside the rotating cylinder. There are two rotating cylinders. A hexagonal insert is fixedly connected to the end face of one rotating cylinder. A slot matching the hexagonal insert is opened to the end face of the other rotating cylinder. The outer surface of the hexagonal insert is inserted into the slot. Brush bristles are fixedly connected at equal intervals to the outer surface of the rotating cylinder. Square plates are fixedly connected at equal intervals to the outer surface of the rotating cylinder.

[0007] Furthermore, the upper surface of the cotton cloth block abuts against the surface of the belt conveyor, and the surface of the brush bristles abuts against the surface of the belt.

[0008] Furthermore, both the positioning groove and the limiting post are hexagonal, and the outer surface of the limiting post is slidably connected to the inside of the positioning groove.

[0009] Furthermore, the end diameter of the limiting rod is larger than the top diameter, the inside of the liquid storage tank is filled with cleaning fluid, and the bottom of the rotating drum is submerged in the cleaning fluid.

[0010] Furthermore, under normal conditions, the elasticity of the spring causes the surface of the abutment plate to press against the inner wall of the positioning groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by setting up cleaning components and cotton cloth blocks, can effectively clean the belt of a belt conveyor. The drive motor drives the drum to rotate, and the square plate can splash the cleaning liquid in the storage tank onto the belt. The brush bristles then scrub the paint stains on the surface of the belt, and the cotton cloth block can wipe the surface of the belt dry. This avoids the problem of workpiece contamination and scratches caused by paint accumulation, ensuring product quality. At the same time, the automated cleaning method also improves cleaning efficiency and reduces the trouble of manual cleaning.

[0013] 2. This utility model has high flexibility and convenience in structural design. The height of the sliding seat can be adjusted by the cooperation of bolts and limit bars, which makes it convenient for workers to clean the liquid storage tank, change the cleaning fluid, and replace worn bristles. The rotating drums are connected by hexagonal plug rods. Combined with the elasticity of springs, the disassembly and assembly of the rotating drums is simple and labor-saving, which facilitates maintenance and upkeep, extends the service life of the equipment, and reduces the cost of use.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] A belt conveyor coating machine includes a belt conveyor 1 and a coating machine body 2 mounted on the belt conveyor 1. Limiting rods 3 are fixedly connected at equal intervals to the bottom of the belt conveyor 1. A sliding seat 4 is longitudinally slidably connected to the outer surface of the limiting rods 3. Bolts 5 are rotatably connected to the bottom of the belt conveyor 1 via bearings. The outer surface of the bolts 5 is threaded into the interior of the sliding seat 4. A liquid storage tank 7 and a placement tank 8 are provided on the surface of the sliding seat 4. A cleaning component 9 is installed inside the liquid storage tank 7, and a cotton cloth block 10 is placed inside the placement tank 8. A drive motor 6 is fixedly mounted on the outer surface of the sliding seat 4, and the output end of the drive motor 6 is fixedly connected to the input end of the cleaning component 9.

[0023] The belt conveyor 1 is installed through the input and output ends of the coating machine body 2. The nozzle inside the coating machine body 2 is located directly above the belt conveyor. The working principle of the coating machine body 2 on the belt conveyor 1 is common knowledge. Without disclosing the specific structure, those skilled in the art can understand its function and the two can be used together.

[0024] In this embodiment, the limit bar 3 and sliding seat 4 at the bottom of the belt conveyor 1 are coordinated with the bolt 5. The height of the sliding seat 4 can be adjusted by rotating the bolt 5, which is convenient for the operator. The liquid storage tank 7 and the placement tank 8 respectively accommodate the cleaning component 9 and the cotton cloth 10. The drive motor 6 provides power to the cleaning component 9, realizing automatic belt cleaning without frequent manual intervention and improving the automation level of the equipment.

[0025] Specifically, the cleaning component 9 includes a connecting shaft 91 rotatably connected to both sides inside the liquid storage tank 7 via bearings. A rotating plate 92 is rotatably connected to the surface of the connecting shaft 91. A limiting post 93 is fixedly connected to the end face of the rotating plate 92 away from the connecting shaft 91. A limiting plate 941 is slidably connected inside the limiting post 93. A connecting rod 94 is fixedly connected to the center of the surface of the limiting plate 941. A limiting plate 941 is fixedly connected to the surface of the limiting plate 941. The limiting plate 941 is movably installed inside the limiting post 93. The connecting rod 94 is located away from the limiting plate 941. A stop plate 95 is fixedly connected to the end, and a rotating cylinder 96 is slidably connected to the outer surface of the stop plate 95. The rotating cylinder 96 has a positioning groove 97 that matches the connecting rod 94 inside. There are two rotating cylinders 96. One rotating cylinder 96 has a hexagonal insert rod 98 fixedly connected to its end face, and the other rotating cylinder 96 has a slot that matches the hexagonal insert rod 98 on its end face. The outer surface of the hexagonal insert rod 98 is inserted into the slot. Brush bristles 99 are fixedly connected at equal intervals to the outer surface of the rotating cylinder 96. Square plates 910 are fixedly connected at equal intervals to the outer surface of the rotating cylinder 96.

[0026] In this embodiment, in the cleaning component 9, the connecting shaft 91 and the rotating plate 92 provide rotational support for the rotating drum 96, and the hexagonal design of the limiting post 93 and the positioning groove 97 ensures stable transmission of the rotating drum 96; the limiting plate 941, the connecting rod 94, the abutment plate 95 and the spring 942 cooperate to make the rotating drum 96 firmly installed; the two rotating drums 96 are connected by the hexagonal insert rod 98 to achieve synchronous rotation, the brush bristles 99 brush the belt stains, and the square plate 910 splashes the cleaning fluid onto the belt. The multiple structures work together to improve the cleaning effect.

[0027] Specifically, the upper surface of the cotton cloth block 10 abuts against the surface of the belt conveyor 1, and the surface of the brush 99 abuts against the surface of the belt.

[0028] In this embodiment, the upper surface of the cotton cloth block 10 contacts the belt of the belt conveyor 1, which can wipe away the residual liquid on the surface of the belt after cleaning; the surface of the brush bristles 99 abuts against the belt to ensure the pressure during brushing, ensuring that the stains are thoroughly cleaned and avoiding residual paint from contaminating subsequent workpieces.

[0029] Specifically, both the positioning groove 97 and the limiting post 93 are hexagonal, and the outer surface of the limiting post 93 is slidably connected to the inside of the positioning groove 97.

[0030] In this embodiment, both the positioning groove 97 and the limiting post 93 are hexagonal, and the limiting post 93 is slidably connected in the positioning groove 97, which can prevent the rotating drum 96 from rotating relative to the limiting post 93, ensuring stable power transmission and ensuring that the brush bristles 99 and the square plate 910 work effectively.

[0031] Specifically, the end diameter of the limiting rod 3 is larger than the top diameter, the inside of the liquid storage tank 7 is filled with cleaning fluid, and the bottom of the rotating drum 96 is submerged in the cleaning fluid.

[0032] In this embodiment, the diameter of the end of the limiting rod 3 is larger than the diameter of the top, which can prevent the sliding seat 4 from falling off the limiting rod 3 and improve the safety of the equipment; the cleaning liquid in the liquid storage tank 7 submerges the bottom of the rotating drum 96, so that the square plate 910 can continuously carry the cleaning liquid when the rotating drum 96 rotates, ensuring a stable supply of cleaning liquid.

[0033] Specifically, under normal conditions, the elasticity of the spring 942 causes the surface of the abutment 95 to abut against the inner wall of the positioning groove 97.

[0034] In this embodiment, under normal conditions, the elasticity of the spring 942 causes the surface of the abutment plate 95 to abut against the inner wall of the positioning groove 97, providing continuous pressure to the rotating drum 96, ensuring that the two rotating drums 96 are tightly connected by the hexagonal insert rod 98, preventing loosening during rotation, and ensuring stable operation of the cleaning assembly 9.

[0035] The working principle and usage process of this utility model are as follows: When in use, the drive motor 6 is started, and the drive motor 6 drives the rotating drum 96 to rotate through the connecting shaft 91 and the rotating plate 92. The two rotating drums 96 are connected by the hexagonal plug 98 to achieve synchronous rotation. When rotating, the square plate 910 throws the cleaning liquid inside the liquid storage tank 7 onto the surface of the belt of the belt conveyor 1. Then, the rotating drum 96 drives the brush 99 to rotate to clean the stains on the belt. After cleaning, the belt surface can be wiped dry when the belt moves through the connection between the belt and the cotton cloth block 10.

[0036] When the bristles 99 wear down after prolonged use and need to be replaced, or when the cleaning fluid needs to be changed inside the storage tank 7, the sliding seat 4 slides downwards outside the limiting rod 3 by turning the bolt 5 counterclockwise. This allows the operator's hands to easily insert into the storage tank 7 for cleaning or changing the cleaning fluid. Then, the operator applies pressure to the two rotating drums 96 in opposite directions. At this time, the rotating drums 96 drive the abutment plate 95 and the connecting rod 94 to slide. The connecting rod 94 drives the limiting plate 941 to slide deeper into the limiting post 93. When the spring 942 is in a compressed state, and the hexagonal insert 98 is disengaged from the slot on the end face of the rotating cylinder 96, the rotating cylinder 96 can be rotated upward around the connecting shaft 91. Then, the rotating cylinder 96 can be directly pulled out from the limiting post 93. Then, the new rotating cylinder 96 is re-sleeved onto the outside of the limiting post 93 through the positioning groove 97. Then, by applying force to both sides of the two rotating cylinders 96 and rotating the rotating cylinders 96, the two rotating cylinders 96 are brought to the same horizontal line. Then, the hexagonal insert 98 is inserted into the slot. At this point, the replacement of the bristles 99 is completed.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
