Description

Technical Field

[0001] The invention relates to the technical field of anti-theft door production, and in particular to production equipment and a production process for molding an outer shell of an anti-theft door. Background Art

[0002] The anti-theft door is mainly composed of a door body, a door frame and a locking system, wherein the door body is composed of a steel anti-theft door shell and fireproof materials filled in the anti-theft door shell. In order to facilitate the processing of the anti-theft door shell, the anti-theft door shell is composed of two separate and mutually engageable shells. The shell is generally cut, stamped, bent and welded with a thinner flat steel to finally become a shell with a door shape. At this time, the shell surface retains the existing characteristics of the steel.

[0003] In order to improve the anti-corrosion performance, coating adhesion and long-term durability of the shell, it is necessary to spray it to form a dense coating on the shell body, so as to ensure that the anti-theft door maintains a stable structure and beautiful appearance in complex environments such as humidity, acid, alkali, high temperature and other environments.

[0004] When spraying the outer shell of the anti-theft door, because the outer shell of the anti-theft door is made of thin steel sheets, the outer shell body has a certain flexibility. Therefore, when workers spray the outer shell, they usually place it on a workbench, and then hold a spray gun to spray the surface of the outer shell placed horizontally on the workbench. After spraying one side of the outer shell, multiple people are required to cooperate, turn the outer shell over, and then spray the other side of the outer shell. However, this method increases the labor intensity of the workers. Secondly, manual spraying has a certain error, and it cannot be guaranteed that each spraying can be sprayed evenly.

[0009] On the basis of the above scheme: the spraying mechanism also includes two bearing bases respectively located on the two ends of the sliding plate, the two bearing bases are connected to the sliding plate and are commonly connected to a rotating shaft, one end of the rotating shaft is provided with a rotating motor for driving the rotating shaft to rotate, and a rotating plate with a U-shaped structure is connected to the rotating shaft through a locking base, and a spraying part is provided on the rotating plate.

[0010] A better solution among the above solutions is that the spraying member is composed of a plurality of water pipes connected to the rotating plate and a connecting water pipe connecting the plurality of water pipes, the shapes of the plurality of water pipes are consistent with the structural shape of the rotating plate, and a plurality of nozzles are provided on one side of the water pipe facing the opening of the rotating plate of the U-shaped structure.

[0011] As a further solution of the present invention: the spraying mechanism also includes a liquid storage tank connected to the side of the sliding plate facing the frame plate, the liquid storage tank is provided with a pump body, the input end of the pump body is connected to an extraction tube with a bending function, and the input end of the extraction tube extends to the interior of the liquid storage tank and is connected to a gravity ball, and a retractable connecting tube is connected between the output end of the pump body and the input end of the water pipe.

[0012] At the same time, the frame plate is rotatably connected to a screw rod, the bottom of the sliding plate is connected to a threaded block threadedly connected to the screw rod, one end of the screw rod is connected to a driven gear, the frame plate is connected to a driving gear meshing with the driven gear, and the frame plate is also connected to a rotating motor whose output end is connected to the driving gear.

[0014] At the same time, columns are vertically provided at the bottom of the four corners of the workbench, and telescopic columns are longitudinally slidably connected to the columns. The ends of the telescopic columns away from the columns are connected to the bottom of the workbench, and a lifting plate is connected to the bottom of the workbench, and a rack is connected to the lifting plate. A lifting motor and a rotating rod are installed between the columns for rotation, and a rotating gear meshing with the lifting plate is connected to the rotating rod, and the output end of the lifting motor is connected to the end of the rotating rod.

[0015] A production process for a production device for molding an outer shell of an anti-theft door, the production process comprising the following steps: S1: When in use, first pull out the placement plate from the workbench to place the shell to be sprayed on the placement plate, and then push the placement plate with the shell placed on it to make it directly below the rotating shaft. At this time, the shell to be sprayed is located in the spraying space 1; S2: Start the telescopic rod, and the movable end of the telescopic rod drives the suction cup to extend axially to the surface of the shell in the placement plate, and under the action of the suction cup, the shell is adsorbed on the movable end of the telescopic rod, and then the driving motor is started to drive the rotating shaft to rotate. Driven by the rotation of the rotating shaft, the rotating frame 1 and the rotating frame 2 rotate synchronously, so that the shell adsorbed on the movable end of the telescopic rod is rotated and moved into the spraying space 2; S3: Then start the spraying assembly in the second nozzle space to spray the surface of the shell directly below it. After the spraying operation is completed, close the spraying assembly and restart the driving motor. The driving motor drives the rotating shaft to rotate by degrees again, so that the shell with the sprayed side returns to the first spraying space. Then the movable end of the telescopic rod will send the shell to the surface position of the placement plate, and then cancel the suction of the suction cup to the shell, so that the shell falls on the concave surface of the placement plate. S4: After the shell is placed on the placement plate, the unsprayed side faces the spraying space 1, the movable end of the telescopic rod drives the suction cup to be recovered, and the driving motor is started again to drive the rotating shaft to rotate by degrees.

As the placement plate moves upward, the distance between the shell and the spray assembly is reduced, which facilitates the spraying operation of the shell by the spray assembly. Then, the spray assembly sprays the shell, and the spraying treatment of the inner and outer surfaces of the shell is completed.

[0016] The beneficial effects of the present invention are: The present invention can transfer the shell from spray space one to spray space two through the cooperation of the suction cup and the telescopic rod, and spray one side surface of the shell in spray space two, and then transfer the shell back to spray space one, and then spray the other unsprayed surface of the shell. At this time, the spraying of the inner and outer surfaces of the shell is completed. In this process, the flipping and spraying of the shell are both achieved through the automated structure, which greatly reduces the labor intensity of the workers. Secondly, through the spraying of the spray assembly, it can be ensured that each spraying can be done evenly, thereby ensuring the quality of the anti-theft door shell during molding.

[0017] The shell is transferred to the second spraying space for spraying, and then transferred to the first spraying space for spraying. At this time, the sprayed side of the shell faces the placement plate, and the unsprayed side faces the first spraying space. The unsprayed side is then sprayed. When spraying in the first spraying space, the rotating shaft is rotated to direct the output end of the spraying assembly on the rotating frame toward the shell. In this process, the shell is flipped over and the suction cup is prevented from contacting the sprayed surface of the shell.

[0018] By arranging a structure that can lift the workbench under the workbench, when the shell is being sprayed in the spray space, the placement plate can be moved toward the output end of the spray group assembly, and the distance between the shell and the nozzle can be adjusted, ensuring that the spray assembly can effectively spray the shell surface and avoiding poor spraying effect caused by excessive distance.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] A production equipment and production process for forming an anti-theft door shell, such as Figure 1-Figure 9 As shown, it includes two symmetrically arranged frames 1, the two frames 1 are rotatably connected with a rotating shaft 2, the rotating shaft 2 is connected with a rotating frame 1 3 and a rotating frame 2 4, the rotating shaft 2 is driven to rotate by a driving motor 5 installed on the frame 1, and according to actual use needs, a rotating shaft 2 with a certain gravity bearing capacity is selected. In the present invention, the size model of the rotating shaft 2 is not limited.

[0032] The production equipment for molding the anti-theft door shell also includes: a suction cup 6, a workbench 8 and a spraying mechanism; specifically, the suction cup 6 is driven to move by a telescopic rod 7 arranged on a rotating frame 2 4, and the suction cup 6 is located on one side of the rotating shaft 2; the rectangular plane where the workbench 8 places the shell is the working surface, and the working surface is longitudinally arranged below the rotating shaft 2, and a spraying space 9 is formed between the workbench 8 and the rotating shaft 2; there are two spraying mechanisms, one of which is connected to the rotating frame and is located on the other side of the rotating shaft 2, and the other spraying mechanism is longitudinally arranged above the rotating shaft 2, and the spraying mechanism is connected to the frame 1, and a spraying space 10 is formed between the frame 1 and the rotating shaft 2. The above structure When used in combination, the shell can be transferred from spraying space 1 9 to spraying space 2 10 through the cooperation of suction cup 6 and telescopic rod 7, and one side surface of the shell is sprayed in spraying space 2 10, and then the shell is transferred back to spraying space 1 9, and then the other unsprayed surface of the shell is sprayed. At this time, the spraying of both the inner and outer surfaces of the shell is completed. In this process, the flipping and spraying of the shell are realized by the automated structure, which greatly reduces the labor intensity of the workers. Secondly, by spraying the spray assembly, it can be ensured that each spraying can be done evenly, thereby ensuring the quality of the anti-theft door shell during molding.

[0033] In the above process, the shell is first transferred to the spraying space 2 10 for spraying, and then transferred to the spraying space 1 9 for spraying. At this time, the sprayed side of the shell faces the placement plate 34, and the unsprayed side faces the spraying space 1 9. The unsprayed side is then sprayed. When spraying in the spraying space 1 9, the rotating shaft 2 is rotated to direct the output end of the spraying assembly on the rotating frame 1 3 toward the shell. In this process, the shell is flipped over while avoiding the suction cup 6 from contacting the already sprayed surface of the shell.

[0034] In order to solve the stability problem of the telescopic rod 7 during the transfer of the housing through the suction cup 6; Figure 1 As shown, there are several telescopic rods 7, and the several telescopic rods 7 are evenly corresponding to the four corners of the working surface. The suction cup 6 is connected to the movable end of the telescopic rod 7. The rotating frame 3 is composed of a support rod 301 and a frame plate 302. The frame plate 302 is connected to the rotating shaft 2 through the support rod 301. The plane where the frame plate 302 is located is parallel to the plane where the movable end of the telescopic rod 7 is located. The several telescopic rods 7 are synchronously adjusted so that they can run synchronously when working, ensuring the stability of the suction cup 6 in the process of carrying the transfer shell.

[0035] In order to solve the problem of spraying the spraying agent evenly on the shell surface; Figure 3-Figure 8As shown, the spraying mechanism includes a sliding track 11 fixedly connected to the frame plate 302. There are two sliding tracks 11 and they are symmetrically arranged on the frame plate 302. Both sliding tracks 11 are provided with a sliding groove 12. A sliding plate 13 is commonly provided on the two sliding tracks 11. The bottom of the sliding plate 13 is connected to a sliding protrusion 14 that is slidably connected to the sliding groove 12, so that the spraying mechanism has a movable supporting structure.

[0036] Then, the spraying mechanism also includes two bearing bases 15 respectively located at the two ends of the sliding plate 13. The two bearing bases 15 are connected to the sliding plate 13 and are commonly connected to a rotating shaft 16. One end of the rotating shaft 2 is provided with a rotating motor 17 for driving the rotating shaft 16 to rotate. A rotating plate 18 with a U-shaped structure is connected to the rotating shaft 16 through a locking base 19, and a spraying part is provided on the rotating plate 18.

[0037] The spraying member is composed of a plurality of water pipes 20 connected to the rotating plate 18 and a connecting water pipe 21 connecting the plurality of water pipes 20. The shapes of the plurality of water pipes 20 are consistent with the structural shape of the rotating plate 18. A plurality of nozzles 22 are provided on one side of the water pipes 20 facing the opening of the rotating plate 18 of the U-shaped structure.

[0038] The spraying mechanism also includes a liquid storage tank 23 connected to the side of the sliding plate 13 facing the frame plate 302, and a pump body 24 is provided on the liquid storage tank 23. The input end of the pump body 24 is connected to an extraction tube 25 with a bending function, and the input end of the extraction tube 25 extends to the interior of the liquid storage tank 23 and is connected to a gravity ball 26. Under the action of the extraction tube 25 and the gravity ball 26, when the rotating shaft 2 drives the spraying component to rotate and displace, it will not affect the pump body 24 to extract the spraying agent in the liquid storage tank 23 through the extraction tube 25. A retractable connecting tube 27 is connected between the output end of the pump body 24 and the input end of the connecting water pipe 21, ensuring that when the rotating plate 18 is deflected, it will not affect the transportation and export of the spraying agent.

[0039] In order to solve the problem of sliding plate 13 moving; Figure 4 As shown, a screw rod 28 is rotatably connected to the frame plate 302, a threaded block 29 threadedly connected to the screw rod 28 is connected to the bottom of the sliding plate 13, one end of the screw rod 28 is connected to a driven gear 30, a driving gear 31 meshing with the driven gear 30 is connected to the frame plate 302, and a rotating motor 32 whose output end is connected to the driving gear 31 is also connected to the frame plate 302. The rotating motor 32 rotates the screw rod 28, and then the universal threaded block 29 drives the sliding plate 13 to move on the sliding track 11.

[0040] For the convenience of placing the housing on the workbench 8; Fig. 9As shown, a guide rail 33 is connected to the working surface of the workbench 8, and the direction in which the end of the guide rail 33 extends is perpendicular to the axial direction of the rotating shaft 2. A placement plate 34 with a concave surface is slidably connected to the guide rail 33, and the concave surface facilitates the placement of the shell and prevents the shell from sliding.

[0041] The bottom of the four corners of the workbench 8 are respectively vertically provided with columns 35, and telescopic columns 36 are longitudinally slidably connected to the columns 35. The end of the telescopic column 36 away from the column 35 is connected to the bottom of the workbench 8, and a lifting plate 37 is connected to the bottom of the workbench 8, and a rack 41 is connected to the lifting plate 37. A lifting motor 40 and a rotating rod 38 are installed between the columns 35, and a rotating gear 39 meshing with the lifting plate 37 is connected to the rotating rod 38. The output end of the lifting motor 40 is connected to the end of the rotating rod 38. By arranging a structure that can lift the workbench 8 below the workbench 8, when the shell is sprayed in the spray space 9, the placement plate 34 can be moved toward the output end of the spray group assembly to adjust the distance between the shell and the nozzle 22, thereby ensuring that the spray assembly can effectively spray the shell surface and avoiding the situation where the spraying effect is poor due to excessive distance.

[0042] When the present embodiment is in use, the placement plate 34 is first pulled out from the workbench 8 to place the shell to be sprayed on the placement plate 34 for convenience. Then, the placement plate 34 on which the shell has been placed is pushed in so that it is located directly below the rotating shaft 2. At this time, the shell to be sprayed is located in the spraying space 1 9. The telescopic rod 7 is started, and the movable end of the telescopic rod 7 drives the suction cup 6 to extend axially to the shell surface in the placement plate 34. Under the action of the suction cup 6, the shell is adsorbed on the movable end of the telescopic rod 7. Then, the driving motor 5 is started to drive the rotating shaft 2 to rotate. Driven by the rotation of the rotating shaft 2, the rotating frame 1 3 and the rotating frame 2 4 rotate synchronously therewith, so that the shell adsorbed on the movable end of the telescopic rod 7 is rotated and moved into the spraying space 2 10.

[0043] Then start the spraying assembly in the nozzle space 2 to spray the shell surface directly below it. After completing the spraying operation, close the spraying assembly and restart the drive motor 5. The drive motor 5 drives the rotating shaft 2 to rotate 180° again, so that the shell with the sprayed side returns to the spraying space 9. Then the movable end of the telescopic rod 7 will send the shell to the surface position of the placement plate 34, and then cancel the adsorption of the suction cup 6 on the shell, so that the shell falls on the concave surface of the placement plate 34. After the shell is placed on the placement plate 34, the unsprayed side faces the spraying space 9, the movable end of the telescopic rod 7 drives the suction cup 6 to be recovered, and the drive motor 5 is started again to drive the rotating shaft 2 to rotate 180°. At this time, the output end of the spraying assembly connected to the rotating frame 3 faces the shell surface.

[0044] Finally, start the lifting motor 40, and then drive the rotating gear 39 to rotate through the rotating rod 38, and drive the end of the rack 41 to move upward through the rotating gear 39, and then drive the workbench 8 and the placement plate 34 to move upward. As the placement plate 34 moves upward, the distance between the shell and the spray assembly is shortened, thereby facilitating the spraying operation of the shell by the spray assembly. Next, the spray assembly sprays the shell, and the spraying process of the inner and outer surfaces of the shell is completed.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

Then the movable end of the telescopic rod (7) will send the shell to the surface position of the placement plate (34), and then the suction cup (6) will cancel the adsorption of the shell, so that the shell falls on the concave surface of the placement plate (34); S4: After the shell is placed on the placement plate (34), the unsprayed side faces the spraying space (9), the movable end of the telescopic rod (7) drives the suction cup (6) to be recovered, and the driving motor (5) is started again to drive the rotating shaft (2) to rotate (180) degrees. At this time, the output end of the spraying assembly connected to the rotating frame (3) faces the shell surface; S5: Start the lifting motor (40), and then drive the rotating gear (39) to rotate through the rotating rod (38), and drive the end of the rack (41) to move upward through the rotating gear (39), thereby driving the workbench (8) and the placement plate (34) to move upward. As the placement plate (34) moves upward, the distance between the shell and the spraying component is shortened, thereby facilitating the spraying operation of the spraying component on the shell. Then, the spraying component sprays the shell, and the spraying process on the inner and outer surfaces of the shell is completed.
