Detailed implementation manners

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, a leather scraping device for a vacuum dryer includes a support platform 1 and a support assembly; a processing platform 11 is fixedly connected to the middle of the support platform 1; two groups of support rods 12 are fixedly connected to one side of the support platform 1; fastening rings 13 are fixedly connected to the tops of the support rods 12; a servo motor 14 is connected to the middle of the fastening ring 13; a first lead screw 15 is fixedly connected to the output end of the servo motor 14; a second lead screw 16 is rotatably connected to the middle of the processing platform 11; scraping plates 17 are threadedly connected to the middle of the first lead screw 15 and the second lead screw 16; two groups of rectangular limit rods 18 are fixedly connected to the inner walls on both sides of the processing platform 11; a chute 113 is opened at the bottom of the processing platform 11; a movable plate 19 is movably connected to the middle of the chute 113; driving pulleys 111 are fixedly connected to one ends of the second lead screw 16 and the first lead screw 15; transmission belts 112 are sleeved on the middle of the driving pulleys 111; during operation, first place the material to be scraped on the movable plate 19, and then drive the support assembly to move the movable plate 19 upward at the chute 113 until the top surface of the movable plate 19 contacts the top of the chute 113, so as to clamp the material to be scraped. At this time, drive the servo motor 14 to work to drive the first lead screw 15 to rotate in the middle of the processing platform 11. Since the transmission belt 112 connects the two driving pulleys 111 to each other, and the rotation of the first lead screw 15 will drive the driving pulley 111 to rotate, which can further drive the second lead screw 16 to rotate. Under the rotation of the first lead screw 15 and the second lead screw 16, the scraping plates 17 will be driven to move. At this time, the scraping plates 17 will change their movement trajectories under the restriction of the rectangular limit rods 18, so that the scraping plates 17 will move linearly in the middle of the first lead screw 15 and the second lead screw 16. And when the scraping plates 17 move, the bottom of the scraping plates 17 will clean the surface of the material, so as to play the role of scraping the skin. Then place the material with the skin scraped on the drying plate inside the vacuum dryer for drying. This step can drive the scraping plates 17 to scrape the surface of the material through the operation of the servo motor 14. When drying specific materials such as leather, it can reduce the effect of surface attachments, thereby preventing the situation that when drying these materials, these attachments are likely to hinder the normal evaporation of moisture, resulting in an extended drying time, reduced drying process and production efficiency due to the fact that these materials are prone to adhering dust, lint and other attachments on their surfaces.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the support assembly includes a support block 2, a drive shaft 21, a rocker 22, a worm 23, a driven shaft 24, a worm wheel 25, and an eccentric block 26; two groups of support blocks 2 are fixedly connected to one side of the processing platform 11; the middle part of the support block 2 is rotatably connected to the drive shaft 21; one end of the drive shaft 21 is fixedly connected to the rocker 22; two groups of worms 23 are fixedly connected to the middle part of the drive shaft 21; two groups of driven shafts 24 are connected to the middle of the slide 113; one end of the driven shaft 24 is fixedly connected to the worm wheel 25; two groups of eccentric blocks 26 are fixedly connected to the middle of the driven shaft 24; the worm wheel 25 and the worm 23 are meshed with each other; during operation, when the material to be shoveled is placed on the movable plate 19, the middle part of the rocker 22 can be held to rotate, and the rotation of the rocker 22 will drive the drive shaft 21 to rotate in the middle of the support block 2, and at the same time, the rotation of the drive shaft 21 will drive the worm 23 to move synchronously, because the worm The reason why the rod 23 and the worm wheel 25 are meshed with each other is that the rotation of the worm 23 drives the worm wheel 25 to rotate, and the rotation of the worm wheel 25 drives the driven shaft 24 to rotate. At this time, the eccentric block 26 will rotate with the rotation of the driven shaft 24, and the rotation of the eccentric block 26 will push the movable plate 19 to slide in the middle of the slide groove 113. When the eccentric block 26 rotates to a certain angle, its top will push the movable plate 19 to fit with the top of the slide groove 113, so as to clamp the material at the movable plate 19. At this time, the rotation of the rocker 22 can be stopped. In this step, the movable plate 19 can be driven by rotating the rocker 22 so that it cooperates with the slide groove 113 to clamp the material. When the scraper 17 is shoveling the material, it can prevent the material from being easily pushed by the scraper 17 and causing a change in position, thereby affecting the shoveling effect of the scraper 17, resulting in incomplete cleaning of the attachments on the surface of the material.

[0026] like Figure 3 , Figure 4 , Figure 5 As shown, the middle of the driven shaft 24 is provided with a plurality of limit grooves 33; the bottom of the processing platform 11 is fixedly connected with a plurality of inclined rods 3; the top of the inclined rods 3 is fixedly connected with a hollow disc 31; both sides are fixedly connected with L-shaped limit rods 32; the L-shaped limit rods 32 and the limit grooves 33 fit each other; during operation, when the driven shaft 24 rotates, it will rotate in the middle of the hollow disc 31, and at the same time, the limit grooves 33 will rotate with the rotation of the driven shaft 24, and when the limit grooves 33 rotate, they start to rotate. Finally, it rotates along the end of the L-shaped limit rod 32. In this step, the inclined rod 3 and the hollow disk 31 are provided to support the driven shaft 24, thereby improving the stability and reliability of the driven shaft 24. The L-shaped limit rod 32 and the limit groove 33 cooperate with each other to limit the rotation trajectory of the driven shaft 24, thereby preventing the driven shaft 24 from easily shifting its front and rear position due to uneven force during rotation, thereby affecting the meshing state of the worm 23 and the worm wheel 25.

[0027] like Figure 5As shown, circular grooves 4 are provided in the middle of the hollow discs 31; a plurality of groups of ball bearings 41 are rotatably connected in the middle of the circular grooves 4; the ball bearings 41 are in contact with the driven shaft 24; during operation, when the driven shaft 24 rotates in the middle of the hollow disc 31, friction will be generated between it and the ball bearings 41. At this time, the ball bearings 41 will rotate in the middle of the circular groove 4 under the action of the frictional force. This step can reduce the friction between the driven shaft 24 and the inner side wall of the hollow disc 31 when the driven shaft 24 rotates by providing the ball bearings 41, thereby preventing the phenomenon that the rotation of the driven shaft 24 is difficult due to excessive frictional force, and further affecting the leather scraping efficiency.

[0028] As Figure 1 , Figure 2 As shown, brush plates 5 are fixedly connected to both sides of the top of the scraper 17; a plurality of groups of bristles 51 are fixedly connected to the bottoms of the brush plates 5; the bottoms of the bristles 51 are in contact with the surfaces of the first lead screw 15 and the second lead screw 16 respectively; during operation, when the scraper 17 moves, it will drive the brush plates 5 and the bristles 51 to move synchronously. During the movement, the bristles 51 will clean the surfaces of the first lead screw 15 and the second lead screw 16. This step can reduce the dust from easily adhering to the surfaces of the first lead screw 15 and the second lead screw 16 along with the air flow by cleaning the surfaces of the first lead screw 15 and the second lead screw 16 with the bristles 51, thereby preventing the situation that the thread meshing state between the scraper 17 and the first lead screw 15 and the second lead screw 16 is affected.

[0029] As Figure 1 , Figure 2 , Figure 3 As shown, guide columns 6 are fixedly connected to the four corners of the bottom of the processing platform 11; during operation, when the eccentric block 26 pushes the movable plate 19 to move, the movable plate 19 will slide in the middle of the guide column 6. This step can limit the movement trajectory of the movable plate 19 by providing the guide column 6, thereby preventing the movable plate 19 from being easily offset to the left and right due to uneven force during movement, and further affecting the clamping effect of the movable plate 19 on the material.

[0030] As Figure 1 , Figure 2 , Figure 3 As shown, a sponge ring 7 is connected to the middle of the rocker 22; during operation, when the operator holds the rocker 22 and rotates, the palm of the hand will contact the sponge ring 7. Thus, by virtue of the special material of the sponge ring 7, the comfort of the operator's hand can be improved. This step can improve the comfort of the operator's hand by providing the sponge ring 7, and at the same time enhance the stability of the hand grip, reducing the phenomenon of slipping caused by sweating or other factors of the hand.

[0031] Working principle: When working, first place the material to be skived on the movable plate 19, and then drive the support component to move the movable plate 19 upward at the chute 113 until the top surface of the movable plate 19 contacts the top of the chute 113, so as to clamp the material to be skived. At this time, drive the servo motor 14 to work to drive the first lead screw 15 to rotate in the middle of the processing platform 11. Since the transmission belt 112 connects the two drive pulleys 111 to each other, and the rotation of the first lead screw 15 will drive the drive pulley 111 to rotate, and then drive the second lead screw 16 to rotate. Under the rotation of the first lead screw 15 and the second lead screw 16, the scraper 17 will move. At this time, the scraper 17 will change its movement trajectory under the restriction of the rectangular limiting rod 18, so that the scraper 17 moves linearly in the middle of the first lead screw 15 and the second lead screw 16, and the bottom of the scraper 17 will clean the surface of the material during the movement, so as to play the role of skiving. Then place the skived material on the drying plate inside the vacuum dryer for drying. This step can drive the scraper 17 to skive the surface of the material through the operation of the servo motor 14, which can reduce the effect of surface attachments when drying specific materials such as leather, etc. Therefore, it can prevent the situation that these attachments are likely to hinder the normal evaporation of moisture when drying these materials, resulting in an extended drying time, reduced drying process and production efficiency. When working, when placing the material to be skived on the movable plate 19, you can hold the middle of the rocker 22 and rotate it. The rotation of the rocker 22 will drive the drive shaft 21 to rotate in the middle of the support block 2. At the same time, the rotation of the drive shaft 21 will drive the worm 23 to move synchronously. Due to the meshing of the worm 23 and the worm wheel 25, the rotation of the worm 23 will drive the worm wheel 25 to rotate, and the rotation of the worm wheel 25 will drive the driven shaft 24 to rotate. At this time, the eccentric block 26 will rotate with the rotation of the driven shaft 24. Under the rotation of the eccentric block 26, it will push the movable plate 19 to slide in the middle of the chute 113. When the eccentric block 26 rotates to a certain angle, its top will push the movable plate 19 to fit with the top of the chute 113, so as to clamp the material at the movable plate 19. At this time, stop rotating the rocker 22. This step can drive the movable plate 19 to cooperate with the chute 113 to clamp the material by rotating the rocker 22, which can prevent the material from being easily pushed by the scraper 17 to cause a change in position during the skiving of the scraper 17, thus affecting the skiving effect of the scraper 17 and resulting in incomplete cleaning of the surface attachments of the material. When working, when the driven shaft 24 rotates, it will rotate in the middle of the hollow disc 31. At the same time, the limiting groove 33 will rotate with the rotation of the driven shaft 24, and the limiting groove 33 always rotates along the end of the L-shaped limiting rod 32 during the rotation. This step can play a role in supporting the driven shaft 24 through the opening of the inclined rod 3 and the hollow disc 31, thereby improving the stability and reliability of the driven shaft 24.With the mutual cooperation of the L-shaped limiting rod 32 and the limiting groove 33, the effect of restricting the rotation trajectory of the driven shaft 24 can be achieved, thereby preventing the situation that the driven shaft 24 is prone to front and rear position offset due to uneven force during rotation, which affects the meshing state of the worm 23 and the worm gear 25. During operation, when the driven shaft 24 rotates in the middle of the hollow disc 31, it will generate friction with the ball 41. At this time, the ball 41 will rotate in the circular groove 4 under the action of the frictional force. This step can reduce the friction between the driven shaft 24 and the inner wall of the hollow disc 31 during rotation by the opening of the ball 41, thereby preventing the phenomenon that the rotation of the driven shaft 24 is difficult due to excessive frictional force, which affects the leather scraping efficiency. During operation, when the scraper 17 moves, it will drive the brush plate 5 and the bristles 51 to move synchronously. During the movement of the bristles 51, the surfaces of the first lead screw 15 and the second lead screw 16 will be cleaned. This step can reduce the situation that dust is easily attached to the surfaces of the first lead screw 15 and the second lead screw 16 along with the air flow, which affects the threaded meshing state of the scraper 17 with the first lead screw 15 and the second lead screw 16 by the cleaning of the surfaces of the first lead screw 15 and the second lead screw 16 by the bristles 51. During operation, when the eccentric block 26 pushes the movable plate 19 to move, the movable plate 19 will slide in the middle of the guide post 6. This step can limit the movement trajectory of the movable plate 19 by the opening of the guide post 6, thereby preventing the situation that the movable plate 19 is prone to left and right offset due to uneven force during movement, which affects the clamping effect of the movable plate 19 on the material. During operation, when the operator holds the rocker 22 and rotates it, the palm of the hand will contact the sponge ring 7. Thus, by virtue of the special material of the sponge ring 7, the comfort of the operator's hand can be improved. This step can improve the comfort of the operator's hand by the opening of the sponge ring 7, and at the same time, it can also enhance the stability of the hand grip and reduce the phenomenon of slipping caused by sweating or other factors on the hand.
