Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sandpaper processing technology, and in particular relates to a curing device for sandpaper processing. Background Technology
[0002] Sandpaper is a commonly used grinding tool, mainly used for surface treatment, grinding, polishing, and removing uneven or rough surfaces. It consists of a substrate and abrasive grains attached to its surface. The different types, hardness, and grit sizes of abrasive grains give sandpaper a variety of uses and properties. To ensure the durability, stability, smoothness, and efficiency of sandpaper, a curing device is used during sandpaper processing to make the bond between the adhesive and the abrasive grains stronger.
[0003] Existing curing devices often rely on hot air to cure sandpaper. In mass production, the sandpaper is often blown away due to its light weight, affecting the curing effect. Therefore, tubular curing methods have emerged. Although they overcome the shortcomings of hot air curing, the curing tubes in tubular curing are mostly fixed connections. During use, the distance between the curing tube and the sandpaper cannot be adjusted according to actual needs, resulting in reduced curing efficiency. Furthermore, the curing length is not adjustable, meaning that the curing tube is still working even after the sandpaper has been cured, causing the sandpaper to be easily overheated and deformed, and wasting resources.
[0004] To address these issues, we provide a curing device for sandpaper processing. Utility Model Content
[0005] The purpose of this invention is to provide a curing device for sandpaper processing. By combining the spacing adjustment component and the sealing component, the problem that the curing spacing and curing length are not adjustable in the existing curing devices when curing sandpaper is being processed is solved.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a curing device for sandpaper processing, comprising a base plate, a conveyor belt on top of the base plate, a heating box on top of the conveyor belt, a suction fan connected to one side of the heating box, a curing box at the bottom of the heating box, and a curing tube inside the curing box; an adjusting assembly on top of the curing tube, the adjusting assembly comprising a first cylinder fixedly connected to the bottom of the heating box, and a movable frame fixedly connected to the output end of the first cylinder, the adjusting assembly adjusting the distance between the curing tube and the sandpaper; a sealing assembly on the front side of the movable frame, the sealing assembly comprising a square tube on the front side of the movable frame, a connecting frame on top of the square tube, a second cylinder fixedly connected to the bottom of the connecting frame, and a sealing plate fixedly connected to the output end of the second cylinder, the sealing assembly adjusting the heating length.
[0008] The present invention is further configured such that the distance adjustment component includes a laser distance sensor fixedly connected to one side of the curing tube, and a threaded telescopic tube communicating with the top of the curing tube, and the distance is measured by the laser distance sensor.
[0009] The present invention is further configured such that a fixed plate is fixedly connected to one side of the curing box, a conveying roller is movably connected to one side of the fixed plate, and a motor is provided on the top of the bottom plate.
[0010] The present invention is further configured such that a vertical plate is fixedly connected to one side of the suction fan, and the bottom of the vertical plate is fixedly connected to the curing box.
[0011] The present invention is further configured such that a heating plate is fixedly connected to one side of the interior of the heating box, and a temperature detection sensor is fixedly connected to the top of the heating box.
[0012] The present invention is further configured such that a pressure relief pipe is connected to one side of the heating box, and a pressure relief valve is sleeved on the surface of the pressure relief pipe.
[0013] The present invention is further configured such that a return pipe is connected to the bottom of the heating box, through which hot air is guided.
[0014] The present invention has the following beneficial effects.
[0015] 1. This invention, by incorporating an adjustable spacing component, allows for the adjustment of the distance between the curing tube and the sandpaper according to actual needs, ensuring uniform and efficient curing. The use of a laser rangefinder further improves the accuracy of the spacing adjustment, avoiding uneven curing or overheating of the sandpaper due to improper spacing. Through the design of the sealing component, this invention can flexibly adjust the heating length of the curing tube according to the length of the sandpaper and curing requirements. The sealing plate design makes the curing length adjustable, preventing the curing tube from continuing to operate even after the sandpaper has finished curing, reducing resource waste, and preventing the sandpaper from deforming due to overheating.
[0016] 2. This invention, through the cooperation of a heating chamber, a suction fan, and a curing tube, can quickly introduce hot air into the curing tube, ensuring uniform heating of the sandpaper during transport and improving curing efficiency. The design of the return pipe further optimizes the circulation of hot air, reducing energy loss. By setting up a pressure gauge and a pressure relief valve, the pressure inside the heating chamber can be monitored in real time, ensuring timely pressure relief when the pressure exceeds the safe value, thus guaranteeing the safety of equipment operation. The use of a temperature detection sensor also ensures the stability of the temperature inside the heating chamber, avoiding poor curing results due to excessively high or low temperatures. This design is suitable for processing sandpaper of different specifications and types, and can be flexibly adjusted according to the thickness, length, and curing requirements of the sandpaper, exhibiting strong versatility and adaptability.

[0028] Example 2
[0029] Please see Figures 1-5Based on Embodiment 1, the distance adjustment assembly further includes a laser rangefinder 13 fixedly connected to one side of the curing tube 6, a threaded telescopic tube 14 communicating with the top of the curing tube 6, and the exhaust end of the suction fan 4 communicating with the threaded telescopic tube 14.

A fixed plate 15 is fixedly connected to one side of the curing box 5, and a conveyor roller 16 is movably connected to one side of the fixed plate 15. A motor 17 is installed on the top of the base plate 1. The fixed plate 15 and the conveyor roller 16 are movably connected by bearings. A conveyor belt 2 is sleeved on the surface of the conveyor roller 16, and the two conveyor rollers 16 are connected by the conveyor belt 2. The motor 17 is fixedly connected to the fixed plate 15. The output end is fixedly connected to the conveyor roller 16. A vertical plate is fixedly connected to one side of the suction fan 4. The bottom of the vertical plate is fixedly connected to the curing chamber 5. A heating plate 18 is fixedly connected to one side inside the heating chamber 3. A temperature detection sensor 19 is fixedly connected to the top of the heating chamber 3. A detection probe is fixedly connected to the bottom of the temperature detection sensor 19. The bottom of the detection probe extends into the interior of the heating chamber 3 for detecting the air temperature inside the heating chamber 3. A pressure relief pipe is connected to one side of the heating chamber 3. A pressure relief valve is sleeved on the surface of the pressure relief pipe. A return pipe 20 is connected to the bottom of the heating chamber 3. The bottom of the return pipe 20 extends into the interior of the curing chamber 5 and is connected to the threaded telescopic pipe 14. Hot air is guided through the return pipe 20.
[0030] The working principle of this invention is as follows: First, the heating plate 18 is activated to heat the air inside the heating chamber 3. The suction fan 4 starts working, guiding the heated air into the curing tube 6 through the threaded telescopic tube 14. The temperature detection sensor 19 monitors the temperature inside the heating chamber 3 in real time to ensure that the temperature remains constant within the set range. When the temperature reaches the set value, the system enters standby mode, ready to perform the sandpaper curing process.
[0031] Start motor 17 to drive conveyor roller 16 and conveyor belt 2 to rotate, and place the sandpaper to be cured on top of conveyor belt 2. The sandpaper enters the curing chamber 5 with the movement of conveyor belt 2, and the hot air in curing pipe 6 heats the sandpaper evenly, so that the adhesive and sand particles on the surface of the sandpaper are firmly bonded, completing the curing process.
[0032] Before the curing process begins, the height of the movable frame 8 is adjusted by the first cylinder 7, which moves the curing tube 6. The laser rangefinder 13 measures the distance between the curing tube 6 and the sandpaper in real time to ensure that the distance is adjusted to the optimal position to improve curing efficiency.
[0033] Based on the length of the sandpaper and the curing requirements, the position of the sealing plate 12 is adjusted by the second cylinder 11 to control the number of ventilation holes in the square tube 9, thereby adjusting the heating length of the curing tube 6. The design of the sealing plate 12 makes the curing length adjustable, avoiding the situation where the sandpaper has completed the curing process while the curing tube 6 is still working, reducing resource waste, and preventing the sandpaper from deforming due to excessive heat.
[0034] During the curing process, a pressure gauge monitors the pressure inside the heating chamber 3 in real time. When the pressure exceeds the set safety value, the pressure relief valve automatically opens to release excess pressure, ensuring the safe operation of the equipment. This allows for efficient and safe curing of sandpaper, and offers high flexibility and adaptability, suitable for processing sandpaper of different specifications and types.
