Description

Technical Field

[0001] This invention is applied to the elevator manufacturing background and is named an elevator door panel grinding and hot pressing manufacturing device. Background Technology

[0002] An elevator is a general term for a means of transportation that moves vertically within a building, and it is generally powered by an electric motor. Elevators can be classified in different ways. Based on their operating method, they can be divided into escalator-type inclined elevators and car-type vertical elevators. Based on their speed, they can be divided into low-speed elevators (below 1 m / s), fast elevators (1-2 m / s), and high-speed elevators (above 2 m / s).

[0003] Comparatively, car-type vertical lifts are more widely used due to their speed and small footprint. Structurally, car-type vertical lifts mainly consist of a machine room, hoistway, car, and floors. Functionally, they can be further subdivided into traction system, guiding system, car, door system, weight balancing system, electric drive system, electrical control system, and safety protection system.

[0004] Hot pressing is a process of heating and pressing a pre-formed fiberboard blank to produce fiberboard with certain mechanical strength and water resistance. Whether it is wet-process production of rigid or semi-rigid boards, or dry-process production of rigid or medium-density fiberboard, hot pressing is necessary to produce the final product.

[0005] However, most existing elevator door panels are made of single-layer or hollow steel plates, which can easily cause dents or safety accidents during daily use. Single-layer door panels are not as strong as those made by hot pressing. The existing hot pressing process usually involves workers cutting and grinding the door panels before sending them to the hot press machine for final shaping and packaging, which wastes time and manpower. Using an integrated machine to grind and then hot press the door panels twice can save time and manpower.

[0006] Therefore, it is necessary to provide an elevator door panel grinding and hot pressing manufacturing device that can achieve the function of elevator manufacturing. Summary of the Invention

[0007] The purpose of this invention is to provide an elevator door panel grinding and hot pressing manufacturing apparatus to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an elevator door panel grinding and hot pressing manufacturing device, comprising a first main compartment, a support frame, and a second main compartment. A first motor is arranged on the outer side of the first main compartment, a second motor is arranged on the outer side of the first main compartment, a support frame is arranged on the front side of the first main compartment, a storage rack is arranged above the support frame, a door panel is arranged inside the storage rack, a third motor is arranged inside the support frame, a first pulley assembly is arranged at the output end of the third motor, a second pulley assembly is connected to the rear bearing of the support frame, and the outer side of the first pulley assembly is engaged with... A belt assembly meshes with a second pulley assembly. A chuck assembly is located at the output end of the second motor, inside the belt assembly. A fourth motor is located inside the first main compartment. A multi-angle transmission belt, driven by the fourth motor, is located inside the chuck assembly. A grinding disc is located at the output end of the first motor, outside the chuck assembly. A first cylinder is located above the first main compartment, with a correction plate at the cylinder's rod. The second main compartment has the same internal structure as the first main compartment.

[0009] In one embodiment, a lower hot press plate is provided above the support frame, a first conveyor belt is provided behind the lower hot press plate, an extension plate is provided above the first main compartment, a second cylinder is fixedly installed below the extension plate, an upper hot press plate is fixedly installed inside the second cylinder at the rod end, a guide rod is provided outside the second cylinder, the sliding end of the guide rod is fixedly installed with the upper hot press plate, and a sliding plate is provided above the support frame.

[0010] In one embodiment, a support shaft is fixedly installed on the rear side of the support frame, a rotating plate is connected to the upper bearing of the support shaft, a suction head is provided on the outer side of the rotating plate, a fifth motor is provided on the rear side of the support shaft, the output end of the fifth motor is fixedly connected to the rotating shaft of the rotating plate, and a second conveyor belt is provided above the second main compartment.

[0011] In one embodiment, an extension bracket is slidably connected to the outer side of the support frame, a third cylinder is fixedly installed above the extension bracket, a balance plate is fixedly installed at the end of the cylinder's air rod, a first frame is fixedly installed on the outer side of the balance plate, a sixth motor is fixedly installed above the first frame, a threaded rod is provided at the output end of the sixth motor, a threaded block is threadedly engaged on the outer side of the threaded rod, a second frame is fixedly installed on the outer side of the threaded block, the second frame is slidably connected to the first frame, a guide rail is provided above the second frame, and a glue applicator is slidably connected inside the guide rail.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention simultaneously grinds the door panel through the first main chamber and the second main chamber. The internal belt assembly, roller assembly, and multi-angle transmission belt work together to enable the door panel to be conveyed in an orderly manner and grinded. At the same time, the vertical position effectively reduces the machine's footprint. Subsequently, the double-layer door panel is overlapped by a rotating plate, and the glue applicator is used to apply glue to the lower door panel and adjust the position of the two door panels to be centered. This makes the entire hot pressing process orderly, efficient, and reduces manpower input. Attached Figure Description

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0024] Please see Figure 1-7This invention provides a technical solution: an elevator door panel grinding and hot pressing manufacturing device, comprising a first main compartment 1, a support frame 15, and a second main compartment 40. A first motor 2 is arranged on the outer side of the first main compartment 1, and a second motor 3 is arranged on the outer side of the first main compartment 1. A support frame 4 is arranged on the front side of the first main compartment 1, and a storage rack 5 is arranged above the support frame 4. A door panel 6 is arranged inside the storage rack 5. A third motor 7 is arranged inside the support frame 4. A first pulley group 8 is arranged at the output end of the third motor 7. A second pulley group 10 is connected to the rear bearing of the support frame 4. A belt group 9 is meshed on the outer side of the first pulley group 8. The belt group 9 and the second pulley group 10 mesh with each other. A chuck group 12 is arranged at the output end of the second motor 3. The chuck group 12 is arranged on the belt... Inside group 9, the first main compartment 1 is equipped with a fourth motor 13. A multi-angle transmission belt 14 is installed inside the first main compartment 1, driven by the fourth motor 13. The multi-angle transmission belt 14 is located inside the chuck assembly 12. A grinding disc 11 is installed at the output end of the first motor 2, and the grinding disc 11 is located outside the chuck assembly 12. A first cylinder 26 is installed above the first main compartment 1, and a correction plate 38 is installed at the cylinder rod of the first cylinder 26. The second main compartment 40 has the same internal structure as the first main compartment 1. Workers need to place the door panel 6 of a specified size into the storage rack 5. Subsequently, the third motor 7 starts, driving the first pulley assembly 8 to rotate. This, in conjunction with the second pulley assembly 10, drives the outer meshing belt assembly 9. The outer side of the belt assembly 9 is high... The door panel 6, made of frictional rubber, slowly descends within the storage rack 5 due to friction against the inner wall of the rack 5. The distance between the door panel 6 and the belt assembly 9 is exactly the thickness of the door panel 6. After the door panel 6 falls onto the belt assembly 9, it begins to follow the transmission due to friction from the belt assembly 9. At this time, the first motor 2, the second motor 3, and the third motor 7 start simultaneously. After the door panel 6 on the belt assembly 9 has been driven to a certain position, it will be driven away from the belt assembly 9 by the inner multi-angle transmission belt 14 and begin to follow the transmission upward. At the same time, the chuck assembly 12 driven by the second motor 3 is located between the multi-angle transmission belts 14. The multi-angle transmission belts 14 are in a semi-circular state around the chuck assembly 12 and are concentric with the chuck assembly 12. Therefore, the door panel 6 is hooked into the hook groove designed on the outside by the chuck assembly 12. At the same time, the multi-angle transmission belt 14 remains in contact with the bottom of the door panel 6, so that the door panel 6 is held by the roller assembly 12 and the multi-angle transmission belt 14 and rotates around the center of the roller assembly 12. While rotating, the grinding disc 11 on the outer side of the multi-angle transmission belt 14 will be driven to rotate by the first motor 2 and pushed inward a short distance by the internally installed propulsion device, so as to contact the door panel 6 and grind the edge of the door panel 6, thereby ensuring that there are no burrs or other debris on the outer side of the finished product. As the rotation progresses, the bottom of the door panel 6 will first detach from the multi-angle transmission belt 14, and then the door panel 6 will be rubbed by the first conveyor belt 17 on the inner side of the roller assembly 12, so as to detach from the roller assembly 12 and be conveyed onto the first conveyor belt 17, thus completing the grinding of the outer edge of the door panel 6 and the orderly conveying of the door panel.In preparation for subsequent hot pressing, since the second main chamber 40 has the same internal structure as the first main chamber 1, the second main chamber 40 and the first main chamber 1 operate simultaneously, respectively transferring and polishing the two door panels 6. When the door panel 6 reaches above the first conveyor belt 17, the correction plate 38 will rotate to align with the first conveyor belt 17 and be propelled by the air rod of the first cylinder 26, correcting the deviation of the door panel 6 and ensuring its edges are flush, facilitating subsequent hot pressing.

[0025] A lower hot press plate 16 is installed above the support frame 15, and a first conveyor belt 17 is installed behind the lower hot press plate 16. A riser plate 22 is installed above the first main compartment 1, and a second cylinder 23 is fixedly installed below the riser plate 22. An upper hot press plate 25 is fixedly installed inside the cylinder 23 at the rod end, and a guide rod 24 is installed on the outside of the cylinder 23. The sliding end of the guide rod 24 is fixedly installed with the upper hot press plate 25. A sliding plate 39 is installed above the support frame 4. When both... When the double-layer door panel 6 is simultaneously on the lower hot press plate 16, the second cylinder 23 is activated, driving the upper hot press plate 25 to fall until it reaches the designated position and applies pressure to the double-layer door panel 6. Then, the frame of the upper hot press plate 25 falls down and contacts the lower hot press plate 16. Subsequently, the upper hot press plate 25 and the lower hot press plate 16 are activated to perform a hot pressing process on the door panel 6. After the hot pressing is completed, the frame of the upper hot press plate 25 returns to its original position, and the second cylinder 23 retracts the upper hot press plate 25 upward, thereby completing the hot pressing process.

[0026] A support shaft 18 is fixedly installed on the rear side of the support frame 15. A rotating plate 19 is connected to the upper bearing of the support shaft 18. A suction head 20 is provided on the outer side of the rotating plate 19. A fifth motor 21 is provided on the rear side of the support shaft 18. The output end of the fifth motor 21 is fixedly connected to the rotating shaft of the rotating plate 19. A second conveyor belt 27 is provided above the second main compartment 40. After the door panel 6 in the second main compartment 40 is polished, it is conveyed by the second conveyor belt 27 to the top of the rotating plate 19. Then the suction head 20 starts to adsorb the door panel 6. The fifth motor 21 starts to drive the rotating plate 19 to rotate 180°, so that the door panel 6 reaches the top of the lower hot press plate 16 and aligns with the door panel 6 polished by the first main compartment 1 on the lower hot press plate 16. Then the suction head 20 releases the door panel 6, and the two door panels 6 come into contact, waiting for hot pressing. Then the fifth motor 21 reverses and returns the rotating plate 19 to its original position, ready for hot pressing.

[0027] An extension bracket 28 is slidably connected to the outer side of the support frame 15. A third cylinder 29 is fixedly installed above the extension bracket 28. A balance plate 30 is fixedly installed at the end of the air rod inside the third cylinder 29. A first frame 31 is fixedly installed on the outer side of the balance plate 30. A sixth motor 32 is fixedly installed above the first frame 31. A threaded rod 33 is provided at the output end of the sixth motor 32. A threaded block 34 is threadedly engaged on the outer side of the threaded rod 33. A second frame 35 is fixedly installed on the outer side of the threaded block 34. The second frame 35 is slidably connected to the first frame 31. A guide rail 36 is provided above the second frame 35. A glue applicator 37 is slidably connected inside the guide rail 36. When the first main compartment 1 sends the door panel 6 onto the lower hot press plate 16, the third cylinder 29 will drive the first frame 31 to extend above the door panel 6 through the air rod. Then, the sixth motor 32 starts and drives the threaded rod 33 to rotate. Due to the threaded engagement of the second frame 34 with the first frame 35, the sixth motor 36 rotates. The frame 35 is slidably connected to the first frame 31, so when the threaded rod 33 rotates, it will drive the second frame 35 to slide back and forth on the first frame 31. At the same time, the glue applicator 37 slides left and right on the guide rail 36, and the extension bracket 28 slides down the support frame 15 a certain distance to make the glue applicator 37 fit with the door panel 6. At this time, the glue applicator 37 will apply glue to the top of the door panel 6 in preparation for subsequent hot pressing. At the same time, the glue applicator 37 is equipped with an existing sensing device that can identify the position of the lower door panel 6 and whether it is centered. The glue applicator 37 uses adsorption devices on all four sides to center and correct the door panel 6 to facilitate glue application and subsequent hot pressing, while avoiding slight displacement of the door panel 6 during the glue application process. Therefore, when applying glue to a part of the area, the door panel 6 will be adsorbed. Similarly, after the door panel 6 brought out by the second main compartment 40 is placed on the lower door panel 6, it will be adsorbed and corrected again, so as to ensure the integrity of the hot pressing process.
