Description

Technical Field

[0002] Abrasive belts are coated abrasives, also known as flexible abrasives. Compared with solid abrasive wheels, they are more flexible and safer when polishing, with higher precision and lower grinding costs. Abrasive belts are a belt-shaped tool that can be used for grinding and polishing. Abrasives are bonded to flexible materials such as paper and cloth using a binder. They are a major form of coated abrasives. Their basic components are: substrate, abrasive and binder, collectively known as the three elements of abrasive belts.

[0003] The method of joining the abrasive belt is to grind the edges of both ends of the abrasive belt, cover them with glue for ring connection, and then manually bond the glue-coated ends. However, manual joints can easily make the bonding surface uneven. Therefore, a hot press is needed to heat press the joints of the abrasive belt.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 7, the present embodiment provides a sanding belt hot pressing bonding device, comprising a base 1, a support frame 2 is fixedly installed on the top of the base 1, a hydraulic cylinder 3 is fixedly installed on the top of the support frame 2, the lower end of the piston rod of the hydraulic cylinder 3 slides through the top of the support frame 2 and then extends into the inner side of the support frame 2, an upper mounting block 4 is fixedly installed on the bottom of the piston rod of the hydraulic cylinder 3, in order to ensure that the upper mounting block 4 can move up and down stably, a limiting rod 201 is fixedly connected to the top of the upper mounting block 4, a limiting sleeve 202 is fixedly installed on the top of the support frame 2, the upper end of the limiting rod 201 slides through the top of the support frame 2 and then slides and is plugged into the limiting sleeve 202, an upper electric heating plate 401 is fixedly installed on the bottom of the upper mounting block 4, a lower mounting block 7 is fixedly installed on the top of the base 1, a lower electric heating plate 701 is fixedly installed on the top of the lower mounting block 7, and the lower electric heating plate 701 is located directly below the upper electric heating plate 401;

[0031] Among them, a clamping mechanism 5 for fixing the two ends of the sanding belt is arranged on the top of the base 1. In this embodiment, the clamping mechanism 5 includes two lower clamping plates 501, and the two lower clamping plates 501 are respectively slidably arranged on both sides of the lower mounting block 7. The tops of the two lower clamping plates 501 are hinged with upper clamping plates 502. The ends of the two lower clamping plates 501 away from the support frame 2 are fixedly connected by lower handles 5011, and the ends of the two upper clamping plates 502 away from the support frame 2 are fixedly connected by upper handles 5021. A locking mechanism 9 is provided that can fix the upper clamping plate 502 on the lower clamping plate 501, wherein the locking mechanism 9 includes a clamping plate, the upper end of the clamping plate is formed with a C-shaped clamping groove 901, the lower end of the clamping plate is formed with a connecting sleeve 902, the connecting sleeve 902 is rotatably sleeved on the lower handle 5011, the C-shaped clamping groove 901 can be clamped on the upper handle 5021, the C-shaped clamping groove 901 is elastic, and in order to facilitate the separation of the C-shaped clamping groove 901 from the upper handle 5021, a shift plate 903 is formed on the top of the clamping plate.

[0032] Through the provided clamping mechanism 5, when in use, the two ends of the sanding belt are respectively placed on the lower clamping plates 501 at the two ends of the clamping mechanism 5, and then the upper handle 5021 is pressed downward so that the upper clamping plate 502 presses the end of the sanding belt onto the lower clamping plate 501, and then the locking mechanism 9 is rotated to insert the C-shaped slot 901 into the upper handle 5021, so that the upper clamping plate 502 can be fixed on the lower clamping plate 501. When the hot-pressed sanding belt needs to be removed from the clamping mechanism 5, the C-shaped slot 901 is pushed away from the upper handle 5021 by pulling the paddle 903, and the sanding belt can be removed from the lower clamping plate 501.

[0033] In order to improve the clamping effect of the clamping mechanism 5 , the top of the lower clamping plate 501 and the bottom of the upper clamping plate 502 are both provided with anti-slip patterns.

[0034] The clamping mechanism 5 is connected to the upper mounting block 4 through the transmission mechanism 6. When the piston rod of the hydraulic cylinder 3 is extended, the clamping mechanism 5 can drive the sanding belt to move directly below the upper electric heating plate 401. When the piston rod of the hydraulic cylinder 3 is retracted, the clamping mechanism 5 can drive the sanding belt to move away from the upper electric heating plate 401.

[0035] In this embodiment, the transmission mechanism 6 includes an upper connecting rod 601, an L-shaped transmission rod 602 and a lower connecting rod 603. The upper connecting rod 601 is fixedly mounted on the side of the upper mounting block 4, and the lower connecting rod 603 is fixedly connected to the side of the lower clamping plate 501. The upper end of the L-shaped transmission rod 602 is rotatably connected to the upper connecting rod 601, and the lower end of the L-shaped transmission rod 602 is rotatably connected to the lower connecting rod 603. Through the provided L-shaped transmission rod 602, when the upper electric heating plate 401 is pressed on the sanding belt, the L-shaped transmission rod 602 will not squeeze the sanding belt outside the clamping mechanism 5. It should be noted that when the piston rod of the hydraulic cylinder 3 retracts and stops, the angle between the L-shaped transmission rod 602 and the lower clamping plate 501 is less than 80°, and the L-shaped transmission rod 602 is elastic, which can make the upper electric heating plate 401 pressed on After the sanding belt is on, the piston rod of the hydraulic cylinder 3 moves downward a short distance. When the pressure is increased, the L-shaped transmission rod 602 can be deformed to ensure the stability of the hot pressing. The structural principle is as follows: when the piston rod of the hydraulic cylinder 3 is extended, it will drive the upper mounting block 4 to move downward, and the upper mounting block 4 moving downward will continuously squeeze the L-shaped transmission rod 602, so that the L-shaped transmission rod 602 pushes the lower clamping plate 501 in the direction close to the upper electric heating plate 401. When the piston rod of the hydraulic cylinder 3 retracts, it will drive the upper mounting block 4 to move upward, and the upper mounting block 4 moving upward will apply an upward pulling force to the L-shaped transmission rod 602, so that the L-shaped transmission rod 602 pulls the lower clamping plate 501 to move away from the upper electric heating plate 401, thereby pushing the clamping mechanism 5 out of the upper electric heating plate 401.

[0036] The clamping mechanism 5 is slidably arranged on the top of the base 1 through a guide mechanism. In this embodiment, the guide mechanism includes a bottom guide rod 804 arranged on the lower clamping plate 501, and both ends of the guide rod 804 are fixedly connected with support blocks 801, and the support block 801 is fixedly installed on the top of the base 1. A slider 802 is slidably arranged on the guide rod 804, and the top of the slider 802 is fixedly connected to the bottom of the lower clamping plate 501. Through this arrangement, the clamping mechanism 5 can be ensured to slide smoothly.

[0037] In order to improve the smoothness of the clamping mechanism 5 when being pushed out from the upper electric heating plate 401, a spring 803 is sleeved on the guide rod 804, one end of the spring 803 is against the support block 801 close to the support frame 2, and the other end of the spring 803 is against one side of the slider 802. The elastic force of the spring 803 is less than the elastic deformation force of the L-shaped transmission rod 602. That is to say, when the L-shaped transmission rod 602 pushes the clamping mechanism 5 to move toward the upper electric heating plate 401, the elastic force of the spring 803 will not cause elastic deformation to the L-shaped transmission rod 602.

[0038] In this embodiment, the adjacent sides of the two lower clamping plates 501 are fixedly connected with extension plates 5012, and the bottom of the extension plate 5012 can be slidably set on the top of the lower mounting block 7. The top of the extension plate 5012 is in the same plane as the top of the lower electric heating plate 701. By setting the extension plate 5012, the end of the sanding belt can be further supported to improve stability.

[0039] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0040] Working principle: When in use, put the two ends of the sanding belt coated with glue on the lower clamping plates 501 at both ends of the clamping mechanism 5 respectively, and then press the upper handle 5021 downward so that the upper clamping plate 502 presses the end of the sanding belt on the lower clamping plate 501, and then rotate the locking mechanism 9 to insert the C-shaped slot 901 into the upper handle 5021, so that the upper clamping plate 502 can be fixed on the lower clamping plate 501, and then turn on the upper electric heating plate 401 and the lower electric heating plate 701 for preheating, and then control the piston rod of the hydraulic cylinder 3 to extend, thereby driving the upper mounting block 4 to move downward, through The upper connecting rod 601 drives the clamping mechanism 5 to move directly below the upper electric heating plate 401, so that the joint of the sanding belt is squeezed between the upper electric heating plate 401 and the lower electric heating plate 701 for hot pressing and bonding. After the hot pressing is completed, the piston rod of the hydraulic cylinder 3 is controlled to retract. At this time, under the action of the spring 803 and the L-shaped transmission rod 602, the pressed sanding belt is moved away from the upper mounting block 4 and pushed out of the hot pressing area. Then, by pulling the paddle 903, the C-shaped slot 901 is pushed away from the upper handle 5021, and the sanding belt can be removed from the lower clamping plate 501.

[0041] The device is more suitable for personal abrasive belt processing or small business processing, with low cost, easy operation and good safety.

[0042] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
