Description

Technical Field

[0001] This utility model relates to the field of oven belts, and in particular to an automatic cleaning device for oven belts. Background Technology

[0002] The oven belt consists of a support frame, control cabinet, conveyor, oven belt body and heating device. It is mainly used for drying and heating battery cells. It is an automatic cleaning device for oven belts and is quite common in the existing technology.

[0003] Existing technologies, such as the utility model with publication number CN211251780U, disclose a printing press oven belt. This patent describes a belt located inside the oven and in contact with solar cells during operation. Several guide strips are spaced apart on the belt, with a height and width of 2-5 mm. This utility model, while maintaining the belt's transmission friction, achieves non-full contact between the solar cells and the belt with minor modifications. This reduces contamination of the solar cells by oil, aluminum powder, and other deposits on the belt surface, thus reducing the generation of failed solar cells. Simultaneously, this utility model can reduce belt deformation and extend the belt's service life.

[0004] The inventors discovered in their daily work that during the process of the battery cells passing through the heating device, many fragments would fall off the battery cells and adhere to the furnace belt. If not cleaned in time, the fragments would stick to the battery cells, and during the subsequent printing process, the fragments would damage the screen and cause abnormal problems such as screen bursting and ink leakage.

[0005] Therefore, it is necessary to provide a new type of oven with an automatic cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in the existing technology, many fragments of the battery cells fall and adhere to the oven belt during the heating process. If cleaning is not timely, the fragments will stick to the battery cells and damage the screen during the subsequent printing process, causing abnormalities such as screen bursting and ink leakage. Therefore, an automatic cleaning device for oven belt is proposed.

[0008] The aforementioned components achieve the following effects: after the battery cells pass through the heating device, personnel can activate the telescopic cylinder to bring the cleaning brush into contact with the furnace belt body. When the cleaning brush needs to be replaced after a long period of use, the rotating plate can be rotated to move the rotating plate away from the connecting plate.

[0010] The effect achieved by the above components is that the limiting rod can limit the movement of the plate and improve the stability of the plate during movement.

[0011] Preferably, an auxiliary plate is fixedly connected to the side of the rotating plate away from the connecting plate, and the cross-section of the auxiliary plate is rectangular.

[0012] The effect achieved by the above components is that the auxiliary plate makes it easier for personnel to rotate the rotating plate, which can improve the ease of operation for personnel.

[0013] Preferably, the inner wall of the auxiliary plate is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the auxiliary plate.

[0014] The effect achieved by the above components is that the anti-slip groove can increase the friction between the personnel's hands and the auxiliary plate, and can prevent the personnel from slipping when moving the auxiliary plate.

[0015] Preferably, a limiting block is fixedly connected to the upper surface of the positioning block.

[0016] The effect achieved by the above components is that the limiting block can limit the rotation plate, making it convenient for personnel to slide the rotation plate into the inner wall of the limiting groove.

[0018] The effect achieved by the above components is that when the tightness of the connection between the furnace belt body and the conveying device decreases due to long-term use, personnel can start the motor to rotate the rotating column until the rotating column is in contact with the furnace belt body and the furnace belt body and the conveying device are tightly in contact.

[0019] Preferably, the inner wall of the protective cover is provided with a plurality of heat dissipation holes, and the plurality of heat dissipation holes are evenly distributed on the protective cover.

[0020] The effect achieved by the above components is that the heat dissipation holes can help the motor dissipate heat and extend the service life of the motor.

[0021] Compared with related technologies, the automatic cleaning device for an oven belt provided by this utility model has the following beneficial effects:

[0022] This utility model provides an automatic cleaning device for oven belts. By setting a cleaning structure, when the oven belt body carries the battery cells past the heating device, the debris on the battery cells will adhere to the oven belt body. At this time, the cleaning structure can clean the attached debris, which can prevent the battery cell debris from adhering to the oven belt body and avoid damage to the screen printing plate in subsequent printing.

[0023] By setting up an auxiliary structure, when the tension between the furnace belt body and the conveying device decreases, the auxiliary structure allows personnel to quickly adjust the tension between the furnace belt body and the conveying device, thereby improving the ease of operation for personnel and the adaptability of the conveying device.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1 The present invention provides an automatic cleaning device for oven belt, comprising: a support frame 1, a conveying device 5 mounted on the upper surface of the support frame 1, a control cabinet 2 mounted on the lower surface of the conveying device 5, an oven belt body 6 mounted inside the conveying device 5, a heating device 7 mounted on the upper surface of the conveying device 5, a cleaning structure 3 provided on the lower surface of the conveying device 5, and an auxiliary structure 4 provided on the inner wall of the conveying device 5.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The cleaning structure 3 includes two fixed plates 301, which are fixedly connected to the conveying device 5. A connecting plate 302 is fixedly connected to the lower surface of the two fixed plates 301. A fixed rod 303 is fixedly connected to the lower surface of the connecting plate 302. A telescopic cylinder 304 is fixedly connected to the side of the fixed rod 303 away from the connecting plate 302. The arc-shaped surface of the output end of the telescopic cylinder 304 is slidably connected to the connecting plate 302. A movable plate 306 is fixedly connected to the output end of the telescopic cylinder 304. A connecting groove 3 is formed on the inner wall of the movable plate 306. 11. A connecting plate 312 is slidably connected to the inner wall of the connecting groove 311. A cleaning brush 307 is fixedly connected to the upper surface of the connecting plate 312. A fixed post 308 and a positioning block 316 are fixedly connected to one side of the moving plate 306. A limiting groove 315 is opened on the inner wall of the positioning block 316. A rotating plate 310 is rotatably connected to the arc surface of the fixed post 308. A coil spring 309 is sleeved on the arc surface of the fixed post 308. The two ends of the coil spring 309 are fixedly connected to the rotating plate 310 and the fixed post 308 respectively. The rotating plate 310 is slidably connected to the limiting groove 315. After the battery cells pass through the heating device 7, personnel can activate the telescopic cylinder 304 to bring the cleaning brush 307 into contact with the furnace belt body 6. When the cleaning brush 307 needs to be replaced after prolonged use, the rotating plate 310 can be rotated away from the connecting plate 312. This prevents battery cell debris from adhering to the furnace belt body 6, avoiding damage to the screen printing plate during subsequent printing, and also improves the speed of replacing the cleaning brush 307. Two limiting rods 305 are slidably connected to the inner wall of the connecting plate 302, and the two limiting rods 305 are fixedly connected to the moving plate 306. The limiting rods 305 can limit the moving plate 306, which can improve the stability of the moving plate 306 during movement. An auxiliary plate 313 with a rectangular cross-section is fixedly connected to the side of the rotating plate 310 away from the connecting plate 312. The auxiliary plate 313 facilitates the rotation of the rotating plate 310, improving operational convenience. Several anti-slip grooves 314 are evenly distributed on the inner wall of the auxiliary plate 313. These grooves increase friction between the user's hand and the auxiliary plate 313, preventing slippage during movement. A limiting block 317 is fixedly connected to the upper surface of the positioning block 316. The limiting block 317 restricts the rotating plate 310, allowing it to slide easily into the inner wall of the limiting groove 315.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary structure 4 includes a rotating rod 41 and a protective cover 45. The rotating rod 41 is rotatably connected to the conveying device 5, and the protective cover 45 is fixedly connected to the conveying device 5. A motor 47 is fixedly connected to the inner wall of the protective cover 45, and the output end of the motor 47 is fixedly connected to the rotating rod 41. A mounting plate 42 is fixedly connected to the arc surface of the rotating rod 41, and a positioning rod 43 is rotatably connected to the inner wall of the mounting plate 42. A rotating column 44 is fixedly connected to the arc surface of the positioning rod 43. This design allows for the rotation of the rotating column 44 by starting the motor 47 when the tightness of the connection between the furnace belt body 6 and the conveying device 5 decreases due to prolonged use. The rotating column 44 is then brought into close contact with the furnace belt body 6, ensuring a tight fit between them. The inner wall of the protective cover 45 has several heat dissipation holes 46 evenly distributed throughout. These holes assist in heat dissipation for the motor 47, extending its service life.

[0036] The working principle of the automatic cleaning device for the oven belt provided by this utility model is as follows: After the battery cells pass through the heating device 7, they are printed by a screen. During the process of the battery cells passing through the heating device 7, the debris on the battery cells will adhere to the oven belt body 6. Then, the operator activates the telescopic cylinder 304. The output end of the telescopic cylinder 304 drives the moving plate 306 to move upward. The moving plate 306 drives the two limit rods 305, the positioning block 316, the connecting plate 312, and the fixing column 308 to move upward. The limiting rod 305 can limit the movement of the movable plate 306, ensuring its stability during movement. Then, the fixing column 308 and the positioning block 316 drive the rotating plate 310 upwards. The fixing column 308 also drives the coil spring 309 upwards, and the positioning block 316 also drives the limiting block 317 upwards. The rotating plate 310 drives the auxiliary plate 313 upwards. Then, the connecting plate 312 drives the cleaning brush 307 upwards until it contacts the furnace belt body 6. Then, when the cleaning brush 307 passes... When the cleaning brush 307 needs to be replaced after prolonged use, the operator can first use the auxiliary plate 313 to rotate the rotating plate 310, causing the rotating plate 310 to rotate away from the positioning block 316. The auxiliary plate 313 facilitates the rotation of the rotating plate 310, improving the operator's ease of operation. Then, the rotating plate 310 also drives the coil spring 309 to rewind until the rotating plate 310 is completely away from the connecting plate 312. The anti-slip groove 314 on the inner wall of the auxiliary plate 313 increases the slip resistance between the operator's hands and the auxiliary plate 313. The friction between them can prevent the personnel from slipping during the movement of the auxiliary plate 313. Then, the personnel move the cleaning brush 307, causing the cleaning brush 307 to move away from the moving plate 306. The cleaning brush 307 drives the connecting plate 312 to move away from the connecting groove 311 until the connecting plate 312 completely slides out of the inner wall of the connecting groove 311. The limiting block 317 on the upper surface of the positioning block 316 can limit the rotating plate 310, which makes it easy for the personnel to slide the rotating plate 310 into the inner wall of the limiting groove 315.

[0037] In addition, when the tension between the furnace belt body 6 and the conveying device 5 decreases, the operator can first start the motor 47. The output end of the motor 47 drives the rotating rod 41 to rotate, the rotating rod 41 drives the mounting plate 42 to rotate, causing the mounting plate 42 to rotate downward. The mounting plate 42 drives the positioning rod 43 to rotate downward, and the positioning rod 43 drives the rotating column 44 to rotate downward until the rotating column 44 is in contact with the furnace belt body 6. Then, the furnace belt body 6 moves part of the furnace belt body 6 downward until the furnace belt body 6 and the conveying device 5 are adjusted to a suitable tension. The heat dissipation holes 46 opened on the inner wall of the protective cover 45 on one side of the conveying device 5 can assist the motor 47 in heat dissipation and can improve the service life of the motor 47.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
