Description

Technical Field

[0001] This utility model relates to the field of packaging sealing technology, specifically a plastic sealing device for packaging flat design samples. Background Technology

[0002] Graphic design refers to design activities in two dimensions. After the graphic design is completed, a sample is produced first. When storing the sample, it needs to be placed in the middle of a plastic film and then sealed to prevent the graphic design sample from being damaged. A sealing device is usually used when sealing the sample.

[0003] Chinese Patent (Authorization Announcement No.: CN 219635653 U, Authorization Announcement Date: 2023.09.05) discloses a molding device for packaging planar design samples. This utility model provides a molding device for packaging planar design samples that can clamp, guide, and transport them, improving the molding quality. The molding device includes a base, a protective cover, a servo motor, and transmission components. The protective cover is connected to the base to protect it. The servo motor is connected to the right side of the base, and transmission components are rotatably connected to both the upper and lower parts of the base. This utility model achieves the effect of clamping, guiding, and transporting planar design samples, thus improving the molding quality, by placing the planar design sample on a sliding frame, pressing down on the pressing block to clamp the sample, and then moving the sliding frame forward to move the sample.

[0004] The aforementioned planar design sample encapsulation device heats and encapsulates the plastic film using a heating roller, but lacks a device for rapid cooling of the encapsulated sample. This can lead to deformation or adhesion of the plastic film due to residual heat, affecting the encapsulation quality. Furthermore, the guide component requires manual pressing of the pressing block and pushing of the sliding frame to complete clamping and conveying, which is cumbersome and inefficient, and cannot achieve automated control. Additionally, the connection between the guide component and the base is not flexible enough, requiring complete disassembly for maintenance or replacement of parts. Therefore, we propose a planar design sample encapsulation device. Utility Model Content

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a plastic sealing device for packaging planar design samples, including a base 1, a guide box 2 provided on the front side of the base 1, a protective cover 3 hinged to the top of the base 1, and mounting plates 11 and 2 are fixedly connected to the left and right sides of the interior of the base 1. The mounting plates 11 are located below the mounting plates 2. Two sets of conveying rollers 4 are rotatably mounted between the front parts of the two sets of mounting plates 2 12, two sets of heating rollers 5 are rotatably mounted between the middle parts of the two sets of mounting plates 2 12, and two sets of cooling rollers 6 are rotatably mounted between the rear parts of the two sets of mounting plates 2 12. A circulating cooling assembly for cooling the cooling rollers 6 is installed on the left side of the interior of the base 1, a guide clamping assembly is installed on the bottom side of the interior of the base 1, and a driving assembly for synchronously rotating the conveying rollers 4, heating rollers 5 and cooling rollers 6 is installed on the right side of the interior of the base 1.

[0025] When the plastic sealing device for packaging planar design samples is in operation, the planar design sample is automatically clamped by the guide clamping component and pushed to the conveyor roller 4. The drive component drives the conveyor roller 4, heating roller 5 and cooling roller 6 to rotate synchronously. The sample passes through the front conveyor roller 4 and enters the space between the heating roller 5 for heating and plastic sealing. Then it enters the space between the rear conveyor roller 4 and the cooling roller 6. The sample is quickly cooled and shaped by the refrigerant circulating in the cooling channel inside the cooling roller 6 through the circulating cooling component. Finally, the sample is output after plastic sealing. The entire process is protected by the protective cover 3 and the guide box 2 guides the sample path.

[0026] The circulating cooling assembly includes a water box 18, which is located inside the left side of the base 1. A semiconductor cooling chip 19 is installed on the inner wall of the water box 18. A circulating pump 20 is also installed inside the left side of the base 1. The input end of the circulating pump 20 is fixedly connected to the water box 18 through a pipe. Mounting plates 32 are also fixedly connected to the left and right sides of the base 1. Cooling channels are opened through both sets of cooling rollers 6. Two sets of rotary joints 33 are installed on both sets of mounting plates 32. The left and right ends of the cooling rollers 6 are fixedly connected to the rotary joints 33. A connecting pipe 34 is fixedly connected between the two sets of rotary joints 33 on the right side. A water outlet pipe 22 is fixedly connected to the rotary joint 33 at the top left side. A water inlet pipe 21 is fixedly connected to the rotary joint 33 at the bottom left side. The input end of the water inlet pipe 21 is fixedly connected to the output end of the circulating pump 20. The output end of the water outlet pipe 22 is fixedly connected to the top of the water box 18.

[0027] When the circulating cooling assembly is in use, a cooling circuit is formed by the water box 18, the semiconductor cooling chip 19 and the circulating pump 20. The semiconductor cooling chip 19 cools the coolant in the water box 18. The circulating pump 20 pumps the low-temperature coolant into the rotary joint 33 at the bottom left through the water inlet pipe 21. The coolant enters the cooling channel of the cooling roller 6 through the rotary joint 33. After absorbing the heat of the roller, it flows back from the rotary joint 33 on the right through the connecting pipe 34 to the rotary joint 33 at the top left. Finally, it returns to the water box 18 through the water outlet pipe 22, forming a closed loop to achieve continuous cooling of the cooling roller 6.

[0028] The guide clamping assembly includes a drive motor 23, which is fixedly installed on the inner bottom side of the base 1. A bidirectional screw 13 is rotatably installed between two sets of mounting plates 11, and a limit rod 14 is fixedly connected between the two sets of mounting plates 11. Sliding plates 15 are threaded on both the left and right sides of the bidirectional screw 13. The front part of the sliding plate 15 is slidably sleeved on the limit rod 14. Several sliding rods 16 are fixedly connected to the top of the sliding plate 15. Clamping plates 17 are fixedly connected to the sliding rods 16. Pulleys 24 are fixedly sleeved on the middle part of the bidirectional screw 13 and the output end of the drive motor 23. A belt 25 is tensioned and sleeved between the two sets of pulleys 24. A linkage clamping mechanism is installed on the guide box 2.

[0029] The linkage clamping mechanism includes two sets of connecting rods 28. The inside of the guide box 2 is provided with a second sliding groove 27. The two sets of connecting rods 28 are slidably connected to the left and right sides of the second sliding groove 27 respectively. The top of the guide box 2 is provided with a first sliding groove 7. The top sides of the two sets of connecting rods 28 are fixedly connected with a second sliding rod 26. The two sets of second sliding rods 26 are slidably connected to the first sliding groove 7. The top ends of the two sets of second sliding rods 26 are fixedly connected with a first clamping plate 8. The rear ends of the two sets of connecting rods 28 are provided with slots 29. The front end of the sliding plate 15 is inserted into the slot 29.

[0030] When the guide clamping assembly is in use, the drive motor 23 drives one set of pulleys 24, which in turn drives the pulleys 24 on the bidirectional screw 13 to rotate via the belt 25. This rotates the bidirectional screw 13, and the bidirectional screw 13 with opposite thread directions on both sides drives the sliding plate 15 to move in opposite directions along the limiting rod 14. The sliding rod 16 at the top of the sliding plate 15 drives the clamping plate 17 to move synchronously to clamp the bottom of the sample. At the same time, the front end of the sliding plate 15 is inserted into the slot 29 at the rear end of the connecting rod 28, pushing the connecting rod 28 to slide along the sliding groove 27 inside the guide box 2. The sliding rod 26 at the top of the connecting rod 28 moves in the sliding groove 7 at the top of the guide box 2, driving the clamping plate 8 to clamp the sample synchronously, thus achieving stable clamping and guiding transport of the sample.

[0031] The drive assembly includes a second drive motor 30, which is fixedly installed inside the right side of the base 1. Gears 31 are fixedly connected to the right ends of the two sets of heating rollers 5, and the two sets of gears 31 mesh with each other. The output shaft of the second drive motor 30 is fixedly connected to the right side of one set of gears 31. Pulleys 4 and 39 are fixedly sleeved on the right sides of the two sets of conveying rollers 4. Pulleys 2 and 35 are fixedly sleeved on the right sides of the two sets of cooling rollers 6. Two sets of pulleys 37 are fixedly sleeved on the right sides of the two sets of heating rollers 5. One set of pulleys 37 and pulleys 2 and 35 are tensioned and sleeved with belt 2 and 36, and the other set of pulleys 37 and pulleys 4 and 39 are tensioned and sleeved with belt 3 and 38.

[0032] When the drive assembly is in use, the right-side gear 31 is driven to rotate by the drive motor 30. The meshing of the two sets of gears 31 drives the other gear 31 to rotate synchronously. The gear 31 is connected to the heating roller 5 and drives its rotation. The pulley 37 on the right side of the heating roller 5 drives the pulley 35 through the belt 36, thereby rotating the cooling roller 6. It also drives the pulley 49 through the belt 38, thereby rotating the conveying roller 4. This results in the synchronous rotation of the conveying roller 4, the heating roller 5, and the cooling roller 6, ensuring that the sample passes through the rollers at a uniform speed, completing the entire process of conveying, heating and sealing, and cooling and shaping.

[0033] The guide box 2 has two fixed insert plates 9 on its rear left and right sides. Both sets of insert plates 9 are inserted into the base 1. The left and right sides of the base 1 are threaded with bolts 10, and the end of the bolt 10 near the insert plate 9 passes through the insert plate 9. The guide box 2 is initially positioned by inserting the insert plates 9 fixed on its rear left and right sides into the corresponding slots of the base 1. After the bolts 10 threaded on the left and right sides of the base 1 are tightened, their front ends pass through the preset holes of the insert plates 9. The thread tightening force securely locks the insert plates 9 onto the base 1, forming a modular connection structure that can be quickly disassembled and assembled, which is convenient for the maintenance or replacement of the guide box 2.

[0034] Working principle: When the plastic sealing device for sample packaging of this planar design is working, the drive motor 23 drives one set of pulleys 24, which in turn drives the pulleys 24 on the bidirectional screw 13 to rotate via belt 25. This rotates the bidirectional screw 13. The bidirectional screw 13 with opposite thread directions on both sides drives the sliding plate 15 to move in opposite directions along the limiting rod 14. The sliding rod 16 at the top of the sliding plate 15 drives the clamping plate 17 to move synchronously to clamp the bottom of the sample. At the same time, the front end of the sliding plate 15 is inserted into the slot 29 at the rear end of the connecting rod 28, pushing the connecting rod 28 to slide along the sliding groove 27 inside the guide box 2. The sliding rod 26 at the top of the connecting rod 28 moves in the sliding groove 7 at the top of the guide box 2, driving the clamping plate 8 to clamp the sample synchronously, realizing the stable clamping and guiding of the sample, and then pushing it to the conveying roller 4.

[0035] The right gear 31 is driven to rotate by the second drive motor 30. The two sets of gears 31 mesh and drive the other gear 31 to rotate synchronously. The gear 31 is connected to the heating roller 5 and drives it to rotate. The pulley 37 on the right side of the heating roller 5 drives the pulley 35 through the second belt 36, thereby rotating the cooling roller 6. It also drives the pulley 49 through the third belt 38, thereby rotating the conveyor roller 4. This forms the synchronous rotation of the conveyor roller 4, the heating roller 5, and the cooling roller 6. The sample passes through the front conveyor roller 4 and enters the space between the heating rollers 5 for heating and sealing. Then it enters the space between the rear conveyor roller 4 and the cooling roller 6.

[0036] A cooling circuit is formed by a water box 18, a thermoelectric cooler 19, and a circulating pump 20. The thermoelectric cooler 19 cools the coolant in the water box 18. The circulating pump 20 pumps the low-temperature coolant into the rotary joint 33 at the bottom left through the water inlet pipe 21. The coolant enters the cooling channel of the cooling roller 6 through the rotary joint 33, absorbs the heat of the roller, and then flows back from the rotary joint 33 on the right through the connecting pipe 34 to the rotary joint 33 at the top left. Finally, it returns to the water box 18 through the water outlet pipe 22, forming a closed loop to achieve continuous cooling of the cooling roller 6. After plastic sealing, the sample is output. The entire process is protected by the protective cover 3, and the guide box 2 guides the sample path.
