Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to an extended double-cylinder synchronous lifting vacuum forming platform. Background Technology

[0002] The vacuum forming platform is an important component of a vacuum forming machine. It is a working platform used to place the vacuum forming mold and support the plastic sheet, providing support and positioning during the vacuum forming process. During vacuum forming, the plastic sheet is heated and softened, and then vacuum-adhered to the vacuum forming mold. The vacuum forming platform ensures that the mold and the sheet maintain a stable positional relationship to achieve precise forming. Sometimes, in order to improve production efficiency, an extended vacuum forming platform is required.

[0003] Due to their larger size, extended vacuum forming platforms need to overcome greater friction and inertial forces during operation. Dual cylinders can provide greater driving force, ensuring that the platform can move smoothly and quickly.

[0004] After prolonged use, the piston seals inside the cylinder may wear out. When the seals wear out, it can cause gas leakage inside the cylinder, reducing the cylinder's thrust or pull force. If the piston seals of the two cylinders wear out at different rates, their output forces will be inconsistent, resulting in uneven platform movement and causing the platform to tilt, which can lead to platform jamming. To address this issue, an extended dual-cylinder synchronous lifting vacuum forming platform is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an extended dual-cylinder synchronous lifting vacuum forming platform, which aims to improve the problem in the prior art where, after long-term use, if the seals of the two cylinders wear differently, the output force will be inconsistent, causing the platform to move unevenly and tilt, ultimately resulting in the platform getting stuck.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an extended double-cylinder synchronous lifting vacuum forming platform, including a support platform, a positioning plate fixedly connected to the inner surface of the support platform, a cylinder fixedly connected to the bottom of the positioning plate, a worktable fixedly connected to the top of the cylinder, and a synchronization mechanism provided at the bottom of the worktable;

[0007] The synchronization mechanism includes a fixed column fixedly connected to the bottom of the workbench, a base plate fixedly connected to the bottom end of the fixed column, a support plate fixedly connected to the top of the base plate, a rotating shaft rotatably connected to the inner wall of the support plate, a gear fixedly connected to the outer arc surface of the rotating shaft, a rack fixedly connected to the bottom end of the workbench, a motor fixedly connected to the top of the base plate, a dustproof component provided at the bottom of the workbench, and a fixing component provided at the front of the workbench.

[0008] As a further description of the above technical solution:

[0009] The dustproof assembly includes a dustproof plate fixedly connected to the bottom of the workbench, a baffle plate rotatably connected to the bottom of the workbench, a through-connection groove opened on the outer wall of the bottom plate, a receiving plate fixedly connected to the inner surface of the through-connection groove, two sets of dustproof plates, and a round hole opened on the outer wall of the right dustproof plate.

[0010] As a further description of the above technical solution:

[0011] A through-connection groove is formed at the center of the positioning plate, and the inner surface of the through-connection groove is larger than the outer surface of the base plate.

[0012] As a further description of the above technical solution:

[0013] The left output end of the motor is fixedly connected to the right end of the rotating shaft.

[0014] As a further description of the above technical solution:

[0015] The front external teeth of the rack mesh with the external teeth of the gear.

[0016] As a further description of the above technical solution:

[0017] The bottom of the rack is slidably connected to the inner wall of the receiving plate.

[0018] As a further description of the above technical solution:

[0019] The fixing component includes a magnetic block fixedly connected to the front end of the workbench, a magnetic plate fixedly connected to the front end of the blocking plate, and the bottom end of the magnetic block being magnetically connected to the front part of the magnetic plate.

[0020] As a further description of the above technical solution:

[0021] A positioning groove is provided at the front of the baffle plate, and a connecting column is fixedly connected to the inner wall of the positioning groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the mutual cooperation between the cylinder, worktable and its synchronization mechanism, the motor drives the rotating shaft to drive the gears on both sides to rotate synchronously. Through the meshing transmission with the rack, the worktable is pushed to rise and fall smoothly, effectively ensuring the synchronous operation of the two sets of cylinders. This not only avoids the platform jamming caused by the cylinders being out of sync, but also improves the stability of the equipment operation, ensures the continuity and reliability of the working process, improves production efficiency, and the dustproof components can reduce the impact of dust on the gears and rack.

In this utility model, through the mutual cooperation between the fixed components and other structures, during maintenance, the staff can easily open the baffle plate to facilitate the inspection, repair or replacement of parts of the motor and rack; after maintenance, the baffle plate can be easily rotated back to its original position to restore the dustproof function. This design greatly improves the maintainability of the equipment and reduces maintenance costs. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1-2This utility model provides an embodiment of an extended dual-cylinder synchronous lifting vacuum forming platform, including a support platform 1. A positioning plate 3 is fixedly connected to the inner surface of the support platform 1. A cylinder 2 is fixedly connected to the bottom of the positioning plate 3. Two sets of cylinders 2 are provided. A worktable 4 is fixedly connected to the top of the cylinders 2. The worktable 4 is driven to move upward by moving the movable end of the top of the cylinder 2. A synchronization mechanism 5 is provided at the bottom of the worktable 4. The synchronization mechanism 5 can drive the two sets of cylinders 2 to move synchronously, thereby avoiding jamming.

[0034] Reference Figures 2-3 The synchronization mechanism 5 includes a fixed column 507 fixedly connected to the bottom of the worktable 4. A base plate 505 is fixedly connected to the bottom end of the fixed column 507. Multiple sets of fixed columns 507 are provided to support the base plate 505. A support plate 506 is fixedly connected to the top of the base plate 505. A rotating shaft 508 is rotatably connected to the inner wall of the support plate 506. Two sets of support plates 506 are provided to support the rotating shaft 508. A gear 504 is fixedly connected to the outer arc surface of the rotating shaft 508. The bottom end of the worktable 4 is fixed... A rack 503 is fixedly connected to the workbench 4. Two sets of rack 503 and gear 504 are provided. A motor 502 is fixedly connected to the top of the base plate 505. The motor 502 is located to the right of the right gear 504. A dustproof component 501 is provided at the bottom of the workbench 4. The dustproof component 501 reduces the amount of dust entering the outside of the gear 504 and rack 503. A fixing component 6 is provided at the front of the workbench 4. The fixing component 6 facilitates the unfolding of the dustproof component 501, thereby facilitating the maintenance of the motor 502.

[0035] Reference Figures 1-2The dustproof component 501 includes a dustproof plate 5011 fixedly connected to the bottom of the workbench 4. A baffle plate 5012 is rotatably connected to the bottom of the workbench 4. The dustproof plate 5011 is arranged horizontally, and the baffle plate 5012 is arranged front and back. The baffle plate 5012 can only rotate 90 degrees. A through-connection groove is opened on the outer wall of the bottom plate 505. A receiving plate 5013 is fixedly connected to the inner surface of the through-connection groove. The receiving plate 5013 can protect the rack 503. Two sets of dustproof plates 5011 are provided. A round hole is opened on the outer wall of the right dustproof plate 5011. The round hole corresponds to the motor 502, so as to facilitate the heat dissipation of the motor 502 in the working state. A through-connection groove is opened at the center of the positioning plate 3. The inner surface of the rack 503 is larger than the outer surface of the base plate 505. This larger size allows the baffle plate 5012 and the dustproof plate 5011 to move vertically normally and also serves as a guide. The left output end of the motor 502 is fixedly connected to the right end of the rotating shaft 508. The rotation of the output end of the motor 502 drives the rotating shaft 508 to rotate. The front external teeth of the rack 503 mesh with the external teeth of the gear 504. The meshing of the two drives the rack 503 to move vertically through the rotation of the gear 504. The rotating shaft 508 allows the two sets of racks 503 to move synchronously, thus avoiding jamming. The bottom of the rack 503 is slidably connected to the inner wall of the receiving plate 5013. This sliding connection avoids motion interference.

[0036] Reference Figures 3-5 The fixing component 6 includes a magnetic block 601 fixedly connected to the front end of the workbench 4, and a magnetic plate 602 fixedly connected to the front end of the blocking plate 5012. Both the magnetic block 601 and the magnetic plate 602 are provided in two sets. The bottom end of the magnetic block 601 is magnetically connected to the front part of the magnetic plate 602. When the blocking plate 5012 rotates forward, the front part of the magnetic plate 602 contacts the bottom of the magnetic block 601, and the parts of the two in contact are of opposite polarity. By using the principle of magnetic attraction between opposite polarities, the blocking plate 5012 in the rotating open state is fixed, thereby facilitating the maintenance operation of the motor 502 or the rack 503 by the staff. A positioning groove is opened at the front of the blocking plate 5012, and a connecting post 603 is fixedly connected to the inner wall of the positioning groove. The setting of the connecting post 603 makes it easy for the staff to hold it manually, thereby rotating the blocking plate 5012.

[0037] Working Principle: The worktable 4 is raised and lowered by two sets of cylinders 2. To ensure the synchronous operation of the two sets of cylinders 2 and avoid jamming during the raising and lowering process, the synchronization mechanism 5 plays a crucial role. The motor 502 is installed on the top right side of the base plate 505, and its left output end is connected to the rotating shaft 508. The rotating shaft 508 is mounted between two sets of support plates 506, and the gear 504 is fixed on the outer arc surface of the shaft. The gear 504 meshes with the rack 503 fixed at the bottom of the worktable 4. When the motor 502 starts, the rotating shaft 508 drives the gears 504 on both sides to rotate synchronously. Through the meshing transmission of the gears 504 and the rack 503, the two sets of racks 503 are pushed to move synchronously in the vertical direction, thereby driving the worktable 4 to rise and fall smoothly, ensuring the synchronous operation of the two cylinders 2 and preventing jamming caused by asynchrony. The dustproof component 501 is used to reduce dust entering the meshing point of the gears 504 and racks 503 and ensure the stability of the transmission system. Dustproof plates 5011 are fixed to the left and right sides of the bottom of the workbench 4, and baffle plates 5012 are rotatably connected to the front and rear sides of the bottom of the workbench 4, forming a protective shell to protect the gear 504 and its rack 503 from dust. A receiving plate 5013 is fixed in the through-connecting groove on the outer wall of the base plate 505, providing protection and guidance for the rack 503. The bottom of the rack 503 slides along the inner wall of the receiving plate 5013 to avoid motion interference. The right-side dustproof plate 5011 has a circular hole corresponding to the motor 502 to ensure effective heat dissipation during motor 502 operation. The through-connecting groove in the center of the positioning plate 3 is larger than that of the base plate 505, reserving space for the vertical movement of the baffle plates 5012 and dustproof plates 5011 to prevent collisions during lifting.

[0038] When maintenance is required, the operator pinches the front connecting post 603 of the baffle plate 5012 and rotates the baffle plate 5012 forward, so that the magnetic plate 602 and the magnetic block 601 are attracted and fixed. At this time, the baffle plate 5012 remains open, exposing the motor 502 and the rack 503, which facilitates the operator to inspect, repair or replace parts. After maintenance is completed, the baffle plate 5012 is manually rotated back to its original position, the magnetic block 601 and the magnetic plate 602 are separated, the baffle plate 5012 closes again, and the dustproof function is restored.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
