Description

Technical Field

[0001] The present invention belongs to the technical field of plastic suction part processing, and specifically relates to a guiding displacement device for plastic suction parts and its working method. Background Technique

[0002] Plastic suction parts are plastic products manufactured through the plastic suction molding process. Plastic suction molding is a thermoforming technology that heats and softens plastic sheets and then uses vacuum adsorption to make them conform to the surface of the mold. After cooling, the desired shape is formed. Plastic suction parts are widely used in fields such as packaging, medical, electronics, food, and daily necessities;

[0003] During the production process of plastic suction parts, in order to ensure the precise positioning and movement of plastic suction parts in processes such as molding, cutting, processing, and assembly, using a guiding displacement device is a common technical means;

[0004] After retrieval, for example, in the patent: CN218082854U, a plastic suction box cutting and positioning device, which includes a bottom plate, two guiding plates, and a cutting and positioning mechanism. The cutting and positioning mechanism includes a lifting drive mechanism and a cutting and positioning seat. The lifting drive mechanism includes a drive motor and an eccentric wheel. The cutting and positioning seat includes a slitting positioning table. The top surface of the slitting positioning table is provided with a limiting surface, and a slitting knife groove is provided on the limiting surface. The plastic suction box strip is stepwise transmitted between the two guiding plates. The drive motor drives the eccentric wheel to rotate, and the rotating eccentric wheel drives the cutting and positioning seat to reciprocate up and down. When the strip is conveyed in place, the slitting positioning table rises to the highest position, and the limiting surface supports and limits the stretching surface of the plastic suction box. At this time, the cutting device can be driven to align the cutting knife with the slitting knife groove direction to cut the plastic suction box, thereby cutting out the plastic suction box. Its structure is simple and easy to use, and it can effectively support and position the plastic suction box during the cutting process, improve the cutting stability, and improve the cutting quality;

[0005] Currently, when cutting and processing plastic suction parts, it is generally common to limit the two sides of the plastic suction parts through two side plates. Although it can prevent the plastic suction parts from generating displacement during the processing, it limits the mobility of the plastic suction parts, thereby reducing the efficiency of the cutting operation. Summary of the Invention

[0006] The purpose of the present invention is to provide a guiding displacement device for plastic suction parts and its working method to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present invention provides the following technical solution: A guiding displacement device for plastic suction parts, including a workbench, a gantry is fixedly installed at the top of the workbench, a hydraulic cylinder is arranged at the top of the gantry, a cutting structure is installed at the bottom end of the hydraulic cylinder, a bearing table is arranged below the cutting structure, the bearing table is slidably installed at the top of the workbench through a moving component, push plates are installed on both sides of the bearing table, and pressing plates are arranged at the tops of the two push plates;

[0008] The moving component includes a first threaded rod and a limiting shaft embedded in the bearing table. The bearing table is threadedly connected to the first threaded rod and slidably connected to the limiting shaft. One end of the first threaded rod is installed with a motor.

[0009] As a further technical solution of the present invention, the push plate is slidably installed inside the bearing table. A first spring is arranged between the push plate and the bearing table. A magnetic block is fixedly installed on one side of the push plate, and a first magnetic plate is magnetically connected to one side of the magnetic block. The first magnetic plate is fixedly installed on the inner wall of the workbench.

[0010] As a further technical solution of the present invention, there are two first magnetic plates, and the two first magnetic plates are symmetrically distributed.

[0011] As a further technical solution of the present invention, a second magnetic plate is arranged between the two first magnetic plates, and the second magnetic plate is fixedly installed on the inner wall of the workbench.

[0012] As a further technical solution of the present invention, the bottom end of the pressing plate is fixedly connected with a connecting plate. The connecting plate is slidably installed inside the push plate. A tension spring is connected between the connecting plate and the push plate. A slider is fixedly installed on one side of the pressing plate, and the slider is slidably installed inside a chute. The chute is opened on the inner wall of the workbench.

[0013] As a further technical solution of the present invention, two limiting plates are installed inside the bearing table. The two limiting plates are both installed inside a second threaded rod. A bevel gear set is fixedly installed on the outer wall of the second threaded rod. A rotating shaft is fixedly installed on one side of the bevel gear set. One end of the rotating shaft far from the bevel gear set is fixedly connected with a rotating block.

[0014] As a further technical solution of the present invention, there are two rotating blocks, and the two rotating blocks are respectively arranged on both sides of the bearing table.

[0015] As a further technical solution of the present invention, a sponge is installed inside one side of the bearing table. The sponge is arranged on the outer wall of the first threaded rod. The top of the sponge is provided with a liquid inlet, which is opened on the top of the bearing table. A third magnetic plate is fixedly installed on the inner wall of the liquid inlet. A baffle is arranged on the top of the third magnetic plate. A connecting shaft is fixedly installed on the top of the baffle, and the connecting shaft is slidably installed inside the workbench.

[0016] As a further technical solution of the present invention, a fixing plate is fixedly installed on the outer wall of the connecting shaft, and a second spring is arranged on the top of the connecting shaft.

[0017] A working method of a guiding displacement device for plastic suction parts includes the following steps:

[0018] S1: When the plastic suction part is cut and processed, first place the plastic suction part on the top of the bearing table and make it located between two push plates and below the pressing plate. Then, control the motor to start through the PLC. When the motor starts, it drives the first threaded rod to rotate, and the rotation of the first threaded rod drives the bearing table to move towards one side of the cutting structure;

[0019] S2: At the same time, the movement of the bearing table drives the movement of the third magnetic plate. When the third magnetic plate moves below the baffle, the two repel each other and cause the baffle to move upward. The lubricating liquid inside the workbench is discharged into the liquid inlet through the liquid discharge port and absorbed by the sponge. During the movement of the bearing table, the lubricating liquid is smeared on the outer wall of the first threaded rod. When the baffle moves upward, it drives the connecting shaft to move upward, and the movement of the connecting shaft drives the movement of the fixing plate. The movement of the fixing plate deforms the second spring to store elastic potential energy. When the third magnetic plate is separated from the baffle, the elastic potential energy is released through it to make the baffle move downward and reset;

[0020] S3: At the same time, the movement of the bearing table drives the movement of the push plates, and the movement of the push plates drives the movement of the magnetic blocks. When the magnetic blocks are separated from the first magnetic plate, the elastic potential energy is released through the first spring to make the push plates move inward. The two push plates move inward simultaneously to contact the edge of the plastic suction part and push the plastic suction part to adjust its position to make it straight. Subsequently, the bearing table continues to move, and the magnetic blocks are magnetically connected to the second magnetic plate, and the two push plates open outward;

[0021] S4: At the same time, the movement of the bearing table drives the movement of the connecting plate, the movement of the connecting plate drives the movement of the pressing plate, and the movement of the pressing plate drives the slider to slide on the inner wall of the chute. The slider slides down through the guidance of the inclined section of the chute. At the same time, the elastic potential energy of the tension spring is used to pull the connecting plate downward, and the movement of the connecting plate drives the movement of the pressing plate to press the edges on both sides of the plastic suction part;

[0022] S5: When the bearing table carries the plastic suction part and moves below the cutting structure, the cutting structure is driven by the hydraulic cylinder to move downward to cut the plastic suction part, and finally the bearing table is removed from below the cutting structure;

[0023] S6: Meanwhile, the carrier table continues to move. The movement of the carrier table drives the movement of the push plate, and the movement of the push plate drives the movement of the magnetic block. When the magnetic block moves to one side of another first magnetic plate, the magnetic connection between the two causes the magnetic block to fit with the first magnetic plate, making the two push plates move outward and separate from the plastic suction piece, facilitating the staff to take out the cut plastic suction piece.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. Through the setting of the moving component in the present invention, when the plastic suction piece is cut and processed, first place the plastic suction piece on the top of the carrier table and make it located between the two push plates and below the pressing plate. Then, start the motor through PLC control. When the motor starts, it drives the first threaded rod to rotate. The rotation of the first threaded rod drives the movement of the carrier table, making the carrier table carry the plastic suction piece and move to the lower part of the cutting structure. Then, drive the cutting structure to move downward through the hydraulic cylinder to cut the plastic suction piece. Finally, move the carrier table away from below the cutting structure, which not only facilitates the staff to load and unload materials, but also improves the processing efficiency of the plastic suction piece.

[0026] 2. Through the setting of the two push plates moving inward in the present invention, when the carrier table carries the plastic suction piece and moves to one side of the cutting structure, the movement of the carrier table drives the movement of the push plate, and the movement of the push plate drives the movement of the magnetic block. When the magnetic block separates from the first magnetic plate, the elastic potential energy of the first spring is released to make the push plate move inward. The two push plates move inward simultaneously to contact the edge of the plastic suction piece and push the plastic suction piece to adjust its position and make it straight, which helps to improve the cutting accuracy.

[0027] 3. Through the setting of the chute guiding the slider in the present invention, when the carrier table carries the plastic suction piece and moves to one side of the cutting structure, the slider slides on the inner wall of the chute. The guiding of the inclined section of the chute makes the slider slide down. At the same time, the elastic potential energy of the tension spring is used to pull the connecting plate downward, and the movement of the connecting plate drives the movement of the pressing plate, making the pressing plate press the edges on both sides of the plastic suction piece to ensure its stable position during the cutting process and improve the cutting accuracy.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 8 shown, in the embodiment of the present invention, a guiding and displacement device for plastic suction parts includes a workbench 1, a gantry 2 is fixedly installed at the top of the workbench 1, a hydraulic cylinder 3 is arranged at the top of the gantry 2, a cutting structure 4 is installed at the bottom of the hydraulic cylinder 3, a carrier stage 5 is arranged below the cutting structure 4, the carrier stage 5 is slidably installed at the top of the workbench 1 through a moving component, push plates 9 are installed on both sides of the carrier stage 5, and pressing plates 10 are arranged at the tops of the two push plates 9;

[0039] The moving component includes a first threaded rod 6 and a limiting shaft 7 embedded in the carrier stage 5. The carrier stage 5 is threadedly connected to the first threaded rod 6 and slidably connected to the limiting shaft 7. One end of the first threaded rod 6 is installed with a motor 8.

[0040] When the plastic suction parts are cut, first place the plastic suction parts on the top of the bearing table 5, and make it located between the two push plates 9 and below the pressing plate 10. Then, start the motor 8 through PLC control. When the motor 8 starts, it drives the first threaded rod 6 to rotate. The rotation of the first threaded rod 6 drives the movement of the bearing table 5, so that the bearing table 5 carries the plastic suction parts and moves them below the cutting structure 4. Then, drive the cutting structure 4 to move down by the hydraulic cylinder 3 to cut the plastic suction parts. Finally, move the bearing table 5 away from below the cutting structure 4, which not only facilitates the staff to load and unload materials, but also improves the processing efficiency of the plastic suction parts.

[0041] As Figures 1 to 8 shown, the push plate 9 is slidably installed inside the bearing table 5. A first spring 18 is arranged between the push plate 9 and the bearing table 5. A magnet 15 is fixedly installed on one side of the push plate 9. A first magnetic plate 16 is magnetically connected to one side of the magnet 15. The first magnetic plate 16 is fixedly installed on the inner wall of the workbench 1.

[0042] When the bearing table 5 carries the plastic suction parts and moves to one side of the cutting structure 4, the movement of the bearing table 5 drives the movement of the push plate 9, and the movement of the push plate 9 drives the movement of the magnet 15. When the magnet 15 is separated from the first magnetic plate 16, the elastic potential energy is released through the first spring 18 to make the push plate 9 move inward. The two push plates 9 move inward at the same time and contact the edge of the plastic suction parts, pushing the plastic suction parts to adjust the position and make it straight, which helps to improve the cutting accuracy.

[0043] As Figure 3 shown, there are two first magnetic plates 16, and the two first magnetic plates 16 are symmetrically distributed.

[0044] After the plastic suction parts are cut, the bearing table 5 continues to move. When the magnet 15 moves to one side of another first magnetic plate 16, the magnet 15 is attached to the first magnetic plate 16 through their magnetic connection. Similarly, the movement of the magnet 15 drives the movement of the push plate 9, so that the two push plates 9 move outward and separate from the plastic suction parts, which is convenient for the staff to take out the cut plastic suction parts.

[0045] As Figure 3 shown, a second magnetic plate 17 is arranged between the two first magnetic plates 16. The second magnetic plate 17 is fixedly installed on the inner wall of the workbench 1.

[0046] When the bearing table 5 carries the plastic suction parts and moves to one side of the cutting structure 4, the magnet 15 is separated from the first magnetic plate 16, and the two push plates 9 move inward at the same time to push the plastic suction parts straight. Then, the bearing table 5 continues to move, and the magnet 15 is magnetically connected to the second magnetic plate 17, and the two push plates 9 open outward, so that before cutting the plastic suction parts, the two push plates 9 move inward and then reset, and during cutting, the two push plates 9 do not contact the edge of the plastic suction parts, reducing the pressure on the plastic suction parts and preventing it from deforming.

[0047] AsFigures 4 to 8 As shown in the figure, a connecting plate 11 is fixedly connected to the bottom end of the pressing plate 10. The connecting plate 11 is slidably installed inside the push plate 9. A tension spring 12 is connected between the connecting plate 11 and the push plate 9. A slider 13 is fixedly installed on one side of the pressing plate 10. The slider 13 is slidably installed inside the chute 14. The chute 14 is opened on the inner wall of the workbench 1.

[0048] Both ends of the chute 14 are higher than the middle position, and the connection between the two is inclined.

[0049] Both ends of the tension spring 12 are fixedly connected to the connecting plate 11 and the push plate 9 respectively.

[0050] When the carrying platform 5 moves the plastic suction part towards the cutting structure 4, the slider 13 slides inside the inner wall of the chute 14. The inclined section of the chute 14 guides the slider 13 to slide downwards. At the same time, the elastic potential energy of the tension spring 12 pulls the connecting plate 11 downwards. The movement of the connecting plate 11 drives the movement of the pressing plate 10, so that the pressing plate 10 presses the edges on both sides of the plastic suction part, ensuring its stable position during the cutting process and improving the cutting accuracy.

[0051] Through the symmetrical arrangement of the two ends of the chute 14 and the two first magnetic plates 16, both sides of the device can be loaded and unloaded.

[0052] As Figures 6 to 8 shown, two limiting plates 19 are installed inside the carrying platform 5. Both of the two limiting plates 19 are installed inside the second threaded rod 20. A bevel gear set 21 is fixedly installed on the outer wall of the second threaded rod 20. A rotating shaft 22 is fixedly installed on one side of the bevel gear set 21. One end of the rotating shaft 22 far from the bevel gear set 21 is fixedly connected to a rotating block 23.

[0053] When cutting and processing plastic suction parts of different sizes are required, rotate the rotating block 23. The rotation of the rotating block 23 drives the rotation of the rotating shaft 22. The rotation of the rotating shaft 22 drives the rotation of the bevel gear set 21. The rotation of the bevel gear set 21 drives the rotation of the second threaded rod 20. The rotation of the second threaded rod 20 drives the movement of the limiting plate 19, so that the limiting plate 19 moves towards or away from the push plate 9, changing the distance between the two, limiting the movable distance of the push plate 9, and thus enabling the push plate 9 to align plastic suction parts of different sizes, improving the adaptability of the device.

[0054] As Figure 6 and Figure 7 shown, there are two rotating blocks 23, and the two rotating blocks 23 are respectively arranged on both sides of the carrying platform 5.

[0055] The device can be adjusted on both sides, improving the convenience of operation.

[0056] As Figure 2 andFigure 3 As shown in the figure, a sponge 24 is installed inside one side of the carrier table 5. The sponge 24 is arranged on the outer wall of the first threaded rod 6. A liquid inlet 30 is arranged at the top of the sponge 24. The liquid inlet 30 is opened on the top of the carrier table 5. A third magnetic plate 25 is fixedly installed on the inner wall of the liquid inlet 30. A baffle 26 is arranged at the top of the third magnetic plate 25. A connecting shaft 27 is fixedly installed at the top of the baffle 26. The connecting shaft 27 is slidably installed inside the workbench 1.

[0057] A liquid storage cavity is opened inside the workbench 1, and lubricating oil is preset inside. One side of the liquid storage cavity is connected with a liquid discharge port;

[0058] When the carrier table 5 moves, the movement of the carrier table 5 drives the movement of the third magnetic plate 25. When the third magnetic plate 25 moves below the baffle 26, the two repel each other to make the baffle 26 move upward. The lubricating liquid inside the workbench 1 is discharged into the liquid inlet 30 through the liquid discharge port and is absorbed by the sponge 24. During the movement of the carrier table 5, the lubricating liquid is smeared on the outer wall of the first threaded rod 6, which helps to reduce friction, extend the service life and reduce noise.

[0059] As Figure 2 and Figure 3 shown in the figure, a fixing plate 28 is fixedly installed on the outer wall of the connecting shaft 27, and a second spring 29 is arranged at the top of the connecting shaft 27.

[0060] Through the elastic potential energy of the second spring 29, the baffle 26 is located at the end of the liquid discharge port to prevent the liquid from being discharged from the liquid discharge port;

[0061] When the baffle 26 moves upward, it drives the connecting shaft 27 to move upward. The movement of the connecting shaft 27 drives the movement of the fixing plate 28. The movement of the fixing plate 28 deforms the second spring 29 to store elastic potential energy. When the third magnetic plate 25 is separated from the baffle 26, the elastic potential energy is released through it to make the baffle 26 move downward to reset.

[0062] A working method of a guiding displacement device for plastic suction parts includes the following steps:

[0063] S1: When the plastic suction part is cut and processed, first place the plastic suction part on the top of the carrier table 5 and make it located between the two push plates 9 and below the pressing plate 10. Then, control the motor 8 to start through the PLC. When the motor 8 starts, it drives the first threaded rod 6 to rotate. The rotation of the first threaded rod 6 drives the carrier table 5 to move towards one side of the cutting structure 4;

[0064] S2: Meanwhile, the movement of the carrier table 5 drives the movement of the third magnetic plate 25. When the third magnetic plate 25 moves below the baffle 26, the two repel each other, causing the baffle 26 to move upward. The lubricating liquid inside the workbench 1 is discharged through the liquid discharge port into the liquid inlet 30 and absorbed by the sponge 24. During the movement of the carrier table 5, the lubricating liquid is smeared onto the outer wall of the first threaded rod 6. When the baffle 26 moves upward, it drives the connecting shaft 27 to move upward, and the movement of the connecting shaft 27 drives the movement of the fixing plate 28. The movement of the fixing plate 28 deforms the second spring 29 to store elastic potential energy. When the third magnetic plate 25 separates from the baffle 26, the elastic potential energy is released through it to make the baffle 26 move downward to reset;

[0065] S3: Meanwhile, the movement of the carrier table 5 drives the movement of the push plate 9, and the movement of the push plate 9 drives the movement of the magnetic block 15. When the magnetic block 15 separates from the first magnetic plate 16, the elastic potential energy is released through the first spring 18 to make the push plate 9 move inward. The two push plates 9 move inward simultaneously to contact the edge of the plastic part to be adsorbed, and push the plastic part to be adsorbed to adjust its position to make it straight. Subsequently, the carrier table 5 continues to move, and the magnetic block 15 is magnetically connected to the second magnetic plate 17, and the two push plates 9 open outward;

[0066] S4: Meanwhile, the movement of the carrier table 5 drives the movement of the connecting plate 11, the movement of the connecting plate 11 drives the movement of the pressing plate 10, and the movement of the pressing plate 10 drives the slider 13 to slide on the inner wall of the chute 14. The slider 13 slides downward through the guidance of the inclined section of the chute 14. At the same time, the elastic potential energy of the tension spring 12 is used to pull the connecting plate 11 downward, and the movement of the connecting plate 11 drives the movement of the pressing plate 10 to make the pressing plate 10 press the edges on both sides of the plastic part to be adsorbed;

[0067] S5: When the carrier table 5 carries the plastic part to be adsorbed and moves below the cutting structure 4, the cutting structure 4 is driven by the hydraulic cylinder 3 to move downward to cut the plastic part to be adsorbed, and finally the carrier table 5 is moved away from below the cutting structure 4;

[0068] S6: Meanwhile, the carrier table 5 continues to move. The movement of the carrier table 5 drives the movement of the push plate 9, and the movement of the push plate 9 drives the movement of the magnetic block 15. When the magnetic block 15 moves to one side of another first magnetic plate 16, the magnetic block 15 fits with the first magnetic plate 16 through their magnetic connection, causing the two push plates 9 to move outward and separate from the plastic part to be adsorbed, facilitating the staff to take out the cut plastic part to be adsorbed.

[0069] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.

When the motor (8) starts, it drives the first threaded rod (6) to rotate, and the rotation of the first threaded rod (6) drives the bearing table (5) to move towards one side of the cutting structure (4); S2: At the same time, the movement of the bearing table (5) drives the movement of the third magnetic plate (25). When the third magnetic plate (25) moves below the baffle (26), the two repel each other, causing the baffle (26) to move upward. The lubricating liquid inside the workbench (1) is discharged through the liquid discharge port into the liquid inlet (30) and absorbed by the sponge (24). During the movement of the bearing table (5), the lubricating liquid is applied to the outer wall of the first threaded rod (6). When the baffle (26) moves upward, it drives the connecting shaft (27) to move upward, and the movement of the connecting shaft (27) drives the movement of the fixing plate (28). The movement of the fixing plate (28) deforms the second spring (29) to store elastic potential energy. When the third magnetic plate (25) separates from the baffle (26), the elastic potential energy is released to make the baffle (26) move downward to reset; S3: At the same time, the movement of the bearing table (5) drives the movement of the push plate (9), and the movement of the push plate (9) drives the movement of the magnetic block (15). When the magnetic block (15) separates from the first magnetic plate (16), the elastic potential energy is released through the first spring (18) to make the push plate (9) move inward. The two push plates (9) move inward simultaneously to contact the edge of the plastic suction piece and push the plastic suction piece to adjust its position to make it straight. Subsequently, the bearing table (5) continues to move, and the magnetic block (15) is magnetically connected to the second magnetic plate (17), and the two push plates (9) open outward; S4: At the same time, the movement of the bearing table (5) drives the movement of the connecting plate (11), and the movement of the connecting plate (11) drives the movement of the pressing plate (10). The movement of the pressing plate (10) drives the slider (13) to slide on the inner wall of the chute (14). The slider (13) slides down through the guidance of the inclined section of the chute (14). At the same time, the connecting plate (11) is pulled downward by the elastic potential energy of the tension spring (12). The movement of the connecting plate (11) drives the movement of the pressing plate (10) to press the edges on both sides of the plastic suction piece; S5: When the bearing table (5) carries the plastic suction piece and moves below the cutting structure (4), the cutting structure (4) is driven by the hydraulic cylinder (3) to move downward to cut the plastic suction piece, and finally the bearing table (5) is moved away from below the cutting structure (4); S6: Meanwhile, the carrier table (5) continues to move. The movement of the carrier table (5) drives the movement of the push plate (9), and the movement of the push plate (9) drives the movement of the magnetic block (15). When the magnetic block (15) moves to one side of another first magnetic plate (16), the magnetic connection between the two causes the magnetic block (15) to fit with the first magnetic plate (16), so that the two push plates (9) move outwards and separate from the plastic suction piece, facilitating the staff to take out the cut plastic suction piece.
