Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to a paint stripping furnace feeding device that prevents material accumulation. Background Technology

[0002] A paint stripping furnace is a device specifically designed to remove coatings (such as paint, powder coatings, and films) from the surface of metal or non-metal workpieces. It separates the coating from the substrate through high-temperature pyrolysis, combustion, or chemical decomposition, thereby achieving the purpose of paint stripping or cleaning. The paint stripping furnace feeding device is an important component of the paint stripping furnace system.

[0003] The existing paint stripping furnace feeding device uses a method of directly feeding the material into the inside of a conical feed hopper. Under the action of its own gravity and with the assistance of the conical surface, the material can fall into the inside of a screw conveyor. Then, under the screw conveying action of the screw conveyor, the material is lifted and falls into the inside of the paint stripping furnace.

[0004] There are some problems with this paint stripping furnace feeding device. Without a mechanism to disperse and intervene, when too much material is fed into the conical feeding hopper, the material tends to accumulate due to the mutual support between the materials and the electrostatic adsorption of the inner wall of the feeding hopper, which affects the feeding efficiency of the paint stripping furnace. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a paint stripping furnace feeding device that avoids material accumulation. While directly dispersing the material, it causes vibration in the feeding hopper, thereby achieving efficient material dispersion and effectively avoiding material accumulation. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paint stripping furnace feeding device to avoid material accumulation, including a lifting bin, the upper end of which is connected to a feeding bin by evenly distributed bolts, and also includes an anti-accumulation mechanism;

[0007] Anti-accumulation mechanism: It includes a rotating shaft, a dispersion plate, a protective chamber, a connecting rod one, a connecting rod two, and a telescopic column. The rotating shaft is symmetrically rotatably connected to the inside of the feeding chamber. The dispersion plate is fixedly connected to the middle of the rotating shaft. The protective chambers are fixedly connected to the front and rear ends of the feeding chamber. The front and rear ends of the rotating shaft are fixedly connected to the connecting rod one. The lower end of the connecting rod one is rotatably connected to the connecting rod two. The lower ends of two horizontally adjacent connecting rods two are rotatably connected to the upper end of the same connecting seat. A telescopic column is set at the center of the bottom wall of the protective chamber. The telescopic end of the telescopic column is fixedly connected to the lower end of the vertically adjacent connecting seat. While directly dispersing the material, it causes vibration of the feeding chamber, realizing efficient dispersion of the material and effectively preventing material accumulation.

[0008] Furthermore, the anti-accumulation mechanism also includes springs, all of which are fixedly connected between the connecting seat and the vertically adjacent bottom wall of the protective chamber. The springs are also movably sleeved on the outer surface of the adjacent telescopic columns to provide driving force for the resetting of the dispersion plate.

[0009] Furthermore, the anti-accumulation mechanism also includes connecting ropes and impact balls. The connecting ropes are symmetrically fixed to the ends of the two dispersion plates away from the center of the feed hopper. The lower ends of the connecting ropes are fixedly connected to impact balls, which are installed in conjunction with the inner wall of the feed hopper to cause vibration of the feed hopper.

[0010] Furthermore, a control switch group is provided on the left side of the feeding bin. The input terminal of the control switch group is electrically connected to an external power source to control various electrical appliances.

[0011] Furthermore, the material lifting hopper is internally connected to a rotating shaft, and the outer surface of the rotating shaft is provided with spiral blades. A motor is installed at the front end of the material lifting hopper. The rear end of the output shaft of the motor is fixedly connected to the front end of the rotating shaft. The input end of the motor is electrically connected to the output end of the control switch group. The front end of the material lifting hopper is connected to a motor protective cover through evenly distributed connecting bolts to realize the spiral conveying of materials.

[0012] Furthermore, two crushing rollers are rotatably connected to the upper end of the feeding hopper. Gears are fixedly connected to the front ends of both crushing rollers, and the two gears mesh with each other. A second motor is installed at the upper end of the rear surface of the feeding hopper. The front end of the output shaft of the second motor is fixedly connected to the rear end of the longitudinally adjacent crushing roller. The input end of the second motor is electrically connected to the output end of the control switch group to realize the pre-crushing of materials.

[0013] Furthermore, the lower end of the feeding hopper is fixedly connected to two support frames, and the lower end of each support frame is rotatably connected to a movable shaft. The left and right ends of the movable shaft are fixedly connected to movable wheels to facilitate the movement of the feeding device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This paint stripping furnace feeding device that avoids material accumulation has the following advantages:

[0015] The weight of the material acts on the dispersing plate, causing it to rotate downwards. As the material's weight decreases, the spring force acts on the corresponding linkage mechanism, which in turn pushes the dispersing plate to rotate in the opposite direction, thus resetting the dispersing plate and dispersing the material. During the reciprocating rotation of the dispersing plate, the connecting rope pulls the corresponding impact ball, causing it to collide with the inner wall of the feeding hopper and vibrate the hopper. This prevents the material from adhering to the inner wall of the feeding hopper, further improving the degree of material dispersion and effectively preventing material accumulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a paint stripping furnace feeding device that avoids material accumulation, including a lifting bin 1, the upper end of the lifting bin 1 is connected to a feeding bin 2 by evenly distributed bolts, and also includes an anti-accumulation mechanism 3;

[0023] Anti-accumulation mechanism 3: It includes a rotating shaft 31, a dispersing plate 32, a protective chamber 33, a first connecting rod 34, a second connecting rod 35, and a telescopic column 36. The rotating shaft 31 is symmetrically rotatably connected to the inside of the feeding chamber 2. The dispersing plate 32 is fixedly connected to the middle of the rotating shaft 31. The protective chambers 33 are fixedly connected to the front and rear ends of the feeding chamber 2. The first connecting rod 34 is fixedly connected to the front and rear ends of the rotating shaft 31. The lower end of the first connecting rod 34 is rotatably connected to the second connecting rod 35. The lower ends of two horizontally adjacent second connecting rods 35 are rotatably connected to the upper end of the same connecting seat. A telescopic column 36 is provided at the center of the bottom wall of the protective chamber 33. The telescopic ends of the telescopic column 36 are connected to the lower end of the vertically adjacent connecting seat. The anti-accumulation mechanism 3 also includes springs 37, which are fixedly connected between the connecting seat and the bottom wall of the vertically adjacent protective chamber 33. The springs 37 are movably sleeved on the outer surface of the adjacent telescopic columns 36. The anti-accumulation mechanism 3 also includes connecting ropes 38 and impact balls 39. The connecting ropes 38 are symmetrically fixedly connected to the ends of the two dispersing plates 32 furthest from the center of the feed chamber 2. Impact balls 39 are fixedly connected to the lower ends of the connecting ropes 38. The impact balls 39 are fitted into the inner wall of the feed chamber 2. When material falls onto the upper end of the dispersing plate 32, the gravity of the material pushes the dispersing plate 32, causing the corresponding rotating shaft 31 to rotate. Both rotating shafts 31 rotate downwards. When the shaft 31 rotates downwards, it causes the connecting rods 34 at both ends to rotate downwards. The downward rotation of connecting rods 34 causes the upper ends of the adjacent vertical connecting rods 35 to move downwards, thus pushing the corresponding connecting seats downwards. The downward movement of the connecting seats causes the telescopic ends of the telescopic columns 36 to retract, simultaneously compressing the corresponding springs 37. At the same time, the downward movement of the dispersing plate 32, via the connecting rope 38, causes the impact ball 39 to move downwards. The impact ball 39 strikes the inner wall of the feed hopper 2, causing vibration in the feed hopper 2 and preventing material from adhering to the inner wall. When the thrust on the dispersing plate 32 decreases, the elastic force of the springs 37 pushes the corresponding connecting seats upwards, and simultaneously... The extension of the telescopic end of the retractable column 36 and the upward movement of the connecting seat both drive the lower ends of the two vertically adjacent connecting rods 35 to move upward, thereby causing the upper ends of the connecting rods 35 to push the corresponding connecting rods 34 to rotate upward. The upward rotation of the connecting rods 34 drives the vertically adjacent rotating shafts 31 to rotate upward, thereby realizing the upward rotation of the dispersing plate 32. The upward rotation of the dispersing plate 32 pulls the impact ball 39 upward through the connecting rope 38. As materials are continuously fed in, the change in the thrust on the dispersing plate 32 causes the dispersing plate 32 to rotate back and forth, thereby realizing the dispersion of materials. At the same time, the impact ball 39 intermittently impacts the feed hopper 2, further improving the dispersion of materials and ultimately effectively preventing the accumulation of materials.

[0024] Among them: a control switch group 13 is provided on the left side of the feeding bin 1, and the input terminal of the control switch group 13 is electrically connected to an external power supply.

[0025] The material lifting bin 1 is internally connected to a rotating shaft 4, and a spiral blade 5 is provided on the outer surface of the rotating shaft 4. A motor 6 is provided at the front end of the material lifting bin 1. The rear end of the output shaft of the motor 6 is fixedly connected to the front end of the rotating shaft 4. The input end of the motor 6 is electrically connected to the output end of the control switch group 13. A motor protective cover 7 is connected to the front end of the material lifting bin 1 through evenly distributed connecting bolts. The motor protective cover 7 provides all-round protection for the motor 6. The control switch group 13 enables the motor 6 to operate. The rotation of the output shaft of the motor 6 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the spiral blade 5 to rotate, realizing the spiral lifting of the material. The material then enters the interior of the paint stripping furnace through the discharge port of the material lifting bin 1.

[0026] Wherein: the upper end of the feeding bin 2 is rotatably connected to two crushing rollers 8, and the front end of each crushing roller 8 is fixedly connected to a gear 9. The two gears 9 are meshed together. The upper end of the rear surface of the feeding bin 2 is provided with a second motor 10. The front end of the output shaft of the second motor 10 is fixedly connected to the rear end of the longitudinally adjacent crushing roller 8. The input end of the second motor 10 is electrically connected to the output end of the control switch group 13. The second motor 10 is operated by the control switch group 13. The output shaft of the second motor 10 rotates and drives the corresponding crushing roller 8 to rotate. The rotation of the left crushing roller 8 drives the left gear 9 to rotate, which in turn drives the right gear 9 to rotate. The rotation of the right gear 9 drives the right crushing roller 8 to rotate. The two crushing rollers 8 rotating in opposite directions achieve pre-crushing of the material.

[0027] Wherein: the lower end of the feeding bin 1 is fixedly connected to two support frames 11, and the lower end of each support frame 11 is rotatably connected to a movable shaft. The left and right ends of the movable shaft are fixedly connected to movable wheels 12, which push the feeding bin 1. The movable wheels 12 rotate under the action of the movable shaft, thereby realizing the movement of the feeding bin 1 and the feeding bin 2.

[0028] The working principle of the paint stripping furnace feeding device provided by this utility model to avoid material accumulation is as follows: During operation, the operator pushes the lifting bin 1, and the moving wheel 12 rotates under the action of the moving shaft, realizing the movement of the lifting bin 1 and the feeding bin 2. When the lifting bin 1, the feeding bin 2, and other mechanisms move to the designated area, the operator stops pushing the lifting bin 1. Then, the operator controls the switch group 13 to start the motor 10. The output shaft of the motor 10 rotates, driving the corresponding crushing roller 8 to rotate. The rotation of the left crushing roller 8 drives the left gear 9 to rotate, which in turn drives the right gear 9 to rotate. The rotation of the right gear 9 drives the right crushing roller. The two crushing rollers 8 rotate in opposite directions to pre-crush the material. The material then falls onto the upper end of the dispersing plate 32. The weight of the material pushes the dispersing plate 32, causing the corresponding rotating shaft 31 to rotate. Both rotating shafts 31 rotate downwards, causing the connecting rods 34 at both ends to rotate downwards. The downward rotation of connecting rods 34 causes the upper ends of the vertically adjacent connecting rods 35 to move downwards, pushing the corresponding connecting seats downwards. The downward movement of the connecting seats causes the telescopic ends of the telescopic column 36 to contract, simultaneously compressing the corresponding spring 37. Meanwhile, the dispersing plate 32... The connecting rope 38 causes the impact ball 39 to move downwards, impacting the inner wall of the feed hopper 2 and causing vibration, thus preventing material from adhering to the inner wall of the feed hopper 2. When the thrust on the dispersing plate 32 decreases, the elastic force of the spring 37 pushes the corresponding connecting seat upwards, and at the same time, the telescopic end of the corresponding telescopic column 36 extends. The upward movement of the connecting seat causes the lower ends of the two vertically adjacent connecting rods 35 to move upwards, which in turn causes the upper ends of the connecting rods 35 to push the corresponding connecting rod 34 to rotate upwards. The upward rotation of the connecting rod 34 causes the vertically adjacent rotating shaft 31 to rotate upwards, thereby realizing the upward rotation of the dispersing plate 32 and dispersing. The plate 32 rotates upwards, pulling the impact ball 39 upwards via the connecting rope 38. As materials are continuously fed in, the change in the thrust on the dispersing plate 32 causes it to rotate back and forth, thereby dispersing the materials. At the same time, the impact ball 39 intermittently impacts the feeding bin 2, further improving the dispersion of materials and effectively preventing material accumulation. The materials fall into the lifting bin 1, and the control switch group 13 activates the motor 6. The output shaft of the motor 6 rotates, driving the rotating shaft 4 to rotate. The rotating shaft 4 rotates, driving the spiral blade 5 to rotate, thus achieving the spiral lifting of the materials. The materials then enter the paint stripping furnace through the discharge port of the lifting bin 1.

[0029] It is worth noting that the control switch group 13 disclosed in the above embodiments is provided with control buttons that correspond one-to-one with motor 6 and motor 10 and control their switching.
