Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic water tank burr trimming technology, specifically a plastic water tank burr trimming method. Background Technology
[0002] After injection molding, plastic water tanks may have burrs or flash on their edges. Therefore, it is necessary to trim the edges of the plastic water tanks to improve their quality before they leave the factory.
[0003] The existing plastic water tank burr trimming device mainly consists of a clamping assembly and a trimming mechanism. When trimming the plastic water tank, the operator first places the plastic water tank to be trimmed on the workbench. The clamping assembly clamps and fixes the plastic water tank. Then, the motor is started to drive the blade or grinding wheel to rotate at high speed, so that the plastic water tank moves under the blade or grinding wheel for trimming. When the edge of the plastic water tank passes under the grinding wheel, the trimming of the plastic water tank is completed.
[0004] Existing plastic water tank burr trimming devices can only trim one side at a time when processing the burrs on the plastic water tank. For plastic water tanks, the position of the turnover box needs to be adjusted at least four times to complete the burr trimming of the entire water tank. The operation is cumbersome and complicated, which greatly reduces production efficiency. Therefore, a plastic water tank burr trimming device is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a method for trimming the rough edges of plastic water tanks.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A plastic water tank edge trimming device according to this utility model includes a base. Two sliding grooves are provided on the base. T-shaped blocks are arranged in each of the two sliding grooves. Pneumatic cylinders are installed at the top of each of the two T-shaped blocks. Pneumatic rods are fitted to the working ends of each of the two pneumatic cylinders. Fixed blocks are installed at the top of each of the two pneumatic rods. A bidirectional lead screw is rotatably mounted on each of the two fixed blocks. A first motor is mounted on one of the fixed blocks. The output end of the first motor is connected to one end of the bidirectional lead screw. Movable blocks are sleeved on both ends of the bidirectional lead screw. Mounting grooves are provided at the bottom ends of both movable blocks. A first motor is arranged in each of the two mounting grooves. A trimming wheel is installed at the output end of the first motor. Limiting rods are fixed between the two fixed blocks, and the two limiting rods are located on both sides of the bidirectional lead screw, passing through the limiting blocks. Limiting blocks are installed on both side walls of each movable block. A unidirectional lead screw is rotatably mounted in each of the two sliding grooves, passing through the T-shaped blocks. Two... The second electric motor, whose output end is connected to one end of a one-way lead screw, is used to trim the edges of the plastic water tank after it is clamped and fixed. First, the pneumatic cylinder is activated to lower the trimming wheel to the same height as the edge of the plastic water tank to be trimmed. Then, the first electric motor is activated, causing two movable blocks to drive two trimming wheels to move until the two trimming wheels are horizontally in contact with the edge of the plastic water tank. The first motor is then activated to rotate the trimming wheels, and the second electric motor is activated to move the T-shaped block to move the trimming wheels. This allows the trimming wheels to move along the edge of the plastic water tank for trimming, thus enabling simultaneous trimming of both sides of the water tank's edges. When trimming the other two sides, the third electric motor is activated to rotate the clamped water tank via a rotating disc to trim the other two sides' edges. Through the cooperation of the two trimming mechanisms and the rotating mechanism, the rough edges on all four sides of the water tank can be trimmed quickly and efficiently, greatly improving work efficiency. At the same time, by adjusting the distance between the two trimming wheels, trimming of water tanks of different sizes can be achieved.
[0007] Preferably, a third motor is installed on the bottom side of the base. The output end of the third motor is connected to a rotating shaft. A rotating disk is fixed to the top of the rotating shaft. A groove is formed on the rotating disk, and two sliders are arranged in the groove. A clamping plate is fixed to the top of each slider. A bidirectional threaded rod is rotatably installed in the groove and passes through the slider. A second motor is installed on the periphery of the rotating disk. The output end of the second motor is connected to one end of the bidirectional threaded rod. When clamping and fixing the plastic water tank, the second motor is started, causing the bidirectional threaded rod to rotate. This causes the two sliders to move the two clamping plates closer to each other until the two clamping plates contact the side walls of the water tank. Then the second motor stops operating, thereby effectively clamping and fixing the plastic water tank and preventing displacement of the plastic water tank during subsequent trimming.
[0008] Preferably, a connecting plate is fixed to one side wall of each of the two movable blocks, and a dust suction hood is fixed to each of the two connecting plates. Two dust collection boxes are installed on the top side of the base. A suction hose is connected between the dust collection box and the dust suction hood. A negative pressure pump is installed on the top side of the dust collection box. The input port of the negative pressure pump is connected to an air extraction pipe, and the other end of the air extraction pipe is placed inside the dust collection box. The output port of the negative pressure pump is connected to an exhaust pipe. During the trimming process, a large amount of plastic debris is generated. By operating the negative pressure pump, the air extraction pipe draws out the gas from the dust collection box and discharges it through the exhaust pipe, making the inside of the dust collection box a negative pressure state. This allows the plastic debris generated during the trimming process to be sucked into the dust collection box, thus enabling timely cleaning and collection of the plastic debris generated during the trimming process, avoiding the phenomenon of debris flying everywhere, and reducing environmental pollution.
[0009] Preferably, the dust collection box is equipped with a filter screen, and the filter screen is arranged around the port of the suction pipe. When using the device, by setting the filter screen, the port of the suction pipe can be prevented from becoming blocked, thus ensuring the smooth progress of the dust collection operation.
[0010] Preferably, a slag discharge port is provided on one side wall of the dust collection box, and a limiting slide rail is fixed to both sides of the slag discharge port. The two limiting slide rails are fitted with a sealing cover plate. When using the device, the slag discharge port can be opened or closed as needed through the cooperation of the limiting slide rails and the sealing cover plate. By setting the slag discharge interface, it is convenient to take out the collected debris.
[0011] The advantages of this utility model are:
[0012] 1. In the trimming process of this utility model, the pneumatic cylinder is first activated to lower the trimming wheel to the same height as the edge of the water tank to be trimmed. Then, the first motor is activated, causing two movable blocks to drive two trimming wheels to move until the two trimming wheels are horizontally moved and in contact with the edge of the water tank. The first motor is then activated to rotate the trimming wheel, and the second motor is activated to move the T-shaped block to move the trimming wheel. This allows the trimming wheel to move along the edge of the water tank for trimming, thus enabling simultaneous trimming of both sides of the water tank's edge. When trimming the other two sides, the third motor is activated to rotate the rotating disc, which drives the clamped and fixed water tank to rotate, so as to trim the other two sides' edges. Through the cooperation of the two trimming mechanisms and the rotating mechanism, the rough edges of the four sides of the water tank can be quickly and efficiently trimmed, greatly improving work efficiency. At the same time, by adjusting the distance between the two trimming wheels, trimming of water tanks of different sizes can be achieved.
[0013] 2. This utility model generates a large amount of plastic debris during the trimming process. By using a negative pressure pump, the gas in the dust collection box is extracted through the suction pipe and discharged through the exhaust pipe, creating a negative pressure state inside the dust collection box. This allows the plastic debris generated during the trimming process to be sucked into the dust collection box, thus enabling timely cleaning and collection of the plastic debris generated during the trimming process, preventing the debris from flying around and reducing environmental pollution.

[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 scope of protection of the present utility model.
[0022] Please see Figure 1-3As shown, a method for trimming rough edges on a plastic water tank includes a base 1. Two sliding grooves 2 are formed on the base 1. T-shaped blocks 3 are installed in each of the two sliding grooves 2. Pneumatic cylinders 4 are mounted on the top of each of the two T-shaped blocks 3. Pneumatic rods 5 are fitted to the actuating ends of each of the two pneumatic cylinders 4. Fixed blocks 6 are mounted on the top of each of the two pneumatic rods 5. A bidirectional lead screw 7 is rotatably mounted on each of the two fixed blocks 6. A first motor 8 is mounted on one of the fixed blocks 6. The output end of the first motor 8 is connected to one end of the bidirectional lead screw 7. Movable blocks 9 are fitted at both ends of the bidirectional lead screw 7. Mounting grooves 10 are formed at the bottom of each of the two movable blocks 9. Each mounting groove 10 contains a... A first motor 11 is provided, and a trimming wheel 12 is installed at the output end of the first motor 11. A limit rod 14 is fixed between two fixed blocks 6, and the two limit rods 14 are located on both sides of the bidirectional lead screw 7, with the limit rods 14 passing through a limit block 13. Limit blocks 13 are installed on both side walls of each movable block 9. A one-way lead screw 16 is rotatably installed in each of the two sliding grooves 2, and the one-way lead screw 16 passes through a T-shaped block 3. Two second motors 15 are installed on one side wall of the base 1, and the output end of the second motor 15 is connected to one end of the one-way lead screw 16. During operation, after the plastic water tank is clamped and fixed, during trimming, the first... First, start the pneumatic cylinder 4, causing the pneumatic rod 5 to move the fixed block 6 and the trimming wheel 12 downwards until the trimming wheel 12 is at the same height as the edge of the plastic tank to be trimmed. Then, start the first motor 8, causing the double-acting screw 7 to rotate. With the cooperation of the limit rod 14 and the limit block 13, the two movable blocks 9 move closer to each other, causing the trimming wheel 12 to move as well. After the two trimming wheels 12 move horizontally and contact the edge of the plastic tank, the first motor 8 stops. Then, start the first motor 11, causing the trimming wheel 12 to rotate. At the same time, start the second motor 15, causing the unidirectional screw 16 to rotate. This causes the T-shaped block 3 to move the trimming wheel 12, allowing it to move along the edge of the plastic water tank for trimming. This enables simultaneous trimming of both sides of the water tank. While trimming the other two sides, the third motor 17 is activated, causing the rotating disk 18 to rotate the clamped water tank, allowing for trimming of the other two sides. Through the cooperation of the two trimming mechanisms and the rotating mechanism, the rough edges on the four sides of the water tank can be quickly and efficiently trimmed, greatly improving work efficiency. At the same time, by adjusting the distance between the two trimming wheels 12, trimming of water tanks of different sizes can be achieved.
[0023] Please see Figure 4-5As shown, a third motor 17 is mounted on the bottom side of the base 1. The output end of the third motor 17 is connected to a rotating shaft. A rotating disk 18 is fixed to the top of the rotating shaft. A groove 19 is provided on the rotating disk 18, and two sliders are arranged in the groove 19. A clamping plate 22 is fixed to the top of each slider. A bidirectional threaded rod 20 is rotatably mounted in the groove 19 and passes through the sliders. A second motor 21 is mounted on the periphery of the rotating disk 18, and the output end of the second motor 21 is connected to one end of the bidirectional threaded rod 20. During operation, before trimming the plastic water tank, the plastic water tank to be trimmed needs to be clamped and fixed. First, place the plastic water tank to be trimmed on the rotating disk 18, then start the second motor 21 to make the bidirectional threaded rod 20 rotate, which in turn causes the two sliders to drive the two clamping plates 22 to move closer to each other until the two clamping plates 22 move to contact the two side walls of the water tank. Then the second motor 21 stops working, which can effectively clamp and fix the plastic water tank and prevent the plastic water tank from shifting during the subsequent trimming process.
[0024] Please see Figure 1 and Figure 4 As shown, connecting plates are fixed to one side wall of each of the two movable blocks 9, and dust suction hoods 23 are fixed to each of the two connecting plates. Two dust collection boxes 24 are installed on the top side of the base 1. A suction hose 25 connects the dust collection box 24 to the dust suction hood 23. A negative pressure pump 26 is installed on the top side of the dust collection box 24. The input port of the negative pressure pump 26 is connected to a suction pipe 27, and the other end of the suction pipe 27 is located inside the dust collection box 24. The output port of the negative pressure pump 26 is connected to an exhaust pipe 28. A filter screen is installed inside the dust collection box 24, and the filter screen is arranged around the port of the suction pipe 27. A slag discharge port is opened on one side wall of the dust collection box 24 for slag discharge. Both sides of the port are fixedly connected to limit slide rails 29, and the two limit slide rails 29 are fitted with a sealing cover plate 30 for sliding. During operation, a large amount of plastic debris is generated during the trimming process. The negative pressure pump 26 operates to extract the gas from the dust collection box 24 through the suction pipe 27 and discharge it through the exhaust pipe 28, so that the inside of the dust collection box 24 is in a negative pressure state. This allows the plastic debris generated during the trimming process to be sucked into the dust collection box 24 through the suction hose 25, so as to clean and collect the plastic debris generated during the trimming process in a timely manner, avoid the phenomenon of debris flying everywhere, and reduce environmental pollution.
[0025] Working Principle: Existing plastic water tank burr trimming devices can only trim one side at a time. For a given plastic water tank, at least four adjustments of the turnover box are required to complete the trimming of the entire tank's burrs, making the operation cumbersome and complex, significantly reducing production efficiency. Therefore, this paper proposes a new plastic water tank burr trimming method. Before trimming, the plastic water tank to be trimmed needs to be clamped and fixed. First, the plastic water tank to be trimmed is placed on the rotating disk 18, and then the second motor 21 is started. This causes the bidirectional threaded rod 20 to rotate, which in turn causes the two sliders to move the two clamping plates 22 closer together until the two clamping plates 22 contact the side walls of the water tank. At this point, the second motor 21 stops operating, thus effectively clamping and fixing the plastic water tank, preventing displacement during subsequent trimming. After the plastic water tank is clamped and fixed, during trimming, the pneumatic cylinder 4 is first activated, causing the pneumatic rod 5 to move the fixing block 6 and trimming wheel 12 downwards until the trimming wheel 12 is aligned with the edge of the plastic water tank to be trimmed. At the specified height, pneumatic cylinder 4 stops operating, then the first motor 8 is started, causing the double-acting lead screw 7 to rotate. With the cooperation of the limit rod 14 and the limit block 13, the two movable blocks 9 move closer together, causing the trimming wheel 12 to move as well. This continues until the two trimming wheels 12 move horizontally to contact the edge of the plastic tank. At this point, the first motor 8 stops operating, and the first motor 11 is started, causing the trimming wheel 12 to rotate. Simultaneously, the second motor 15 is started, causing the unidirectional lead screw 16 to rotate, which in turn causes the T-block 3 to drive the trimming wheel 12 to move, thus enabling the trimming wheel to rotate. The edge wheel 12 moves along the edge of the plastic water tank for trimming, thus enabling simultaneous trimming of both sides of the water tank. While trimming the other two sides, the third motor 17 is activated, causing the rotating disk 18 to rotate the clamped water tank to trim the other two sides. Through the cooperation of the two trimming mechanisms and the rotating mechanism, the rough edges of the four sides of the water tank can be trimmed quickly and efficiently, greatly improving work efficiency. At the same time, by adjusting the distance between the two trimming wheels 12, trimming of water tanks of different sizes can be achieved.
[0026] During the trimming process, a large amount of plastic debris is generated. The negative pressure pump 26 operates, which draws the gas out of the dust collection box 24 through the suction pipe 27 and discharges it through the exhaust pipe 28, keeping the dust collection box 24 under negative pressure. This allows the plastic debris generated during the trimming process to be sucked into the dust collection box 24 through the suction hose 25, thus enabling timely cleaning and collection of the plastic debris generated during the trimming process, preventing the debris from flying everywhere and reducing environmental pollution.
