Description

Technical Field

[0001] The utility model relates to the technical field of laminators, and specifically relates to a feeding device for an automatic laminator. Background Art

[0002] The working principle of a laminator is to apply a certain pressure on the surface of multiple layers of materials to press these materials tightly together.

[0003] For the existing preparation process before laminating foamed boards, generally, a drill is held manually by a worker to drill holes in the foamed board, and after drilling, additives such as foaming agents, flame retardants, and anti-aging agents are injected into the foamed board, and the feeding holes opened on the foamed board are blocked. After the above processes are completed, the foamed board is sent into the laminator for lamination to extrude the foamed board into a formed shape.

[0004] However, the existing preparation process for foamed boards usually adopts manual methods, generally carried out by 2 - 3 people. One person holds a drilling gun to drill holes, one person holds a feeding gun to feed materials, and finally one person is responsible for sending the board and blocking the materials. Or a robotic arm is used, with a drilling gun and a feeding gun installed on the robotic arm. However, these methods generally have high costs and cannot be automated. Taking the robotic arm as an example, the cost of the robotic arm is lower than the labor cost in the long run, but most robotic arms used on laminators only play an auxiliary role and require manual guidance or operation, and the material blocking process still needs to be carried out manually. The cost of semi-automation is similar to the cost of fully manual operation, and the efficiency still needs to be improved. Summary of the Utility Model

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment: Please refer to Figures 1 to 6 , according to an embodiment of the present utility model, a technical solution is provided: an automatic laminator feeding device, including: a frame 1, a moving platform, multiple connecting plates 4, a drilling structure, a feeding gun 7, and a material blocking structure. Among them, the frame 1 and the support frame 2 can be installed on one side of the laminator. The support frame 2 is fixed on the frame 1 and serves as the basic support structure for the entire feeding device. The moving platform includes a mounting plate 3 and a first driving mechanism. The first driving mechanism installed on the support frame 2 is responsible for pushing the mounting plate 3 to slide along the support frame 2 to achieve automatic horizontal position adjustment. Multiple connecting plates 4 are installed on the mounting plate 3 through sliding connections. Each connecting plate 4 is equipped with a second driving mechanism, and the second driving mechanism drives its respective connecting plate 4 to move towards the laminator to achieve precise positioning at multiple points. The drilling structure installed on a certain connecting plate 4 includes a drill bit 5 and a driving motor 6 for driving the drill bit 5. The drill bit 5 partially extends beyond the edge of the connecting plate 4 and can drill holes in the foam board to prepare for subsequent feeding. The feeding gun 7 installed on a certain connecting plate 4 has its feeding head facing the laminator and extending beyond the connecting plate 4 to ensure that the feeding process can accurately inject into the preset position. The material blocking structure includes a funnel 8, a material blocking pipe 9, and an electric push rod 10, which are installed on a certain connecting plate 4. The bottom of the funnel 8 is connected to the material blocking pipe 9. The output end of the electric push rod 10 extends into the material blocking pipe 9 and is slidably connected thereto. The pushing of the material blocking substance can be controlled through the action of the electric push rod 10, which is used to block the feeding holes drilled by the drill bit 5 after feeding. It should be noted that the first driving mechanism and the second driving mechanism can be driven in a reciprocating motion of the mounting plate 3 or the connecting plate 4 in ways such as an electric push rod 10, a screw motor, a servo motor cooperating with a screw, etc.

[0029] The automatic laminator feeding device with the above structure drives the drilling structure, the feeding gun 7 and the plugging structure located on the connecting plate 4 through the second driving mechanism to move towards the foaming board located in the laminator, and drives the mounting plate 3 to move through the first driving mechanism, driving the drilling structure, the feeding gun 7 and the plugging structure to move horizontally. Thus, after the drilling mechanism drills the foaming board, the feeding gun 7 feeds the drilled feeding hole, and then the plugging rod is inserted into the feeding hole through the plugging structure to complete the automated process of drilling, feeding and plugging. Compared with the robotic arm and manual labor, this structure has a lower cost and can realize the automated process of drilling, feeding and plugging, and the efficiency is also effectively improved, solving the problems in the traditional technology that the cost of semi-automation and full manual labor is relatively high, and it cannot be automated and the efficiency is low.

[0030] During the displacement of the connecting plate 4 and the mounting plate 3 driven by various driving methods, such as electric push rods 10 or screw motors, the response speed and stability are poor. When driving the connecting plate 4 to move, if there is jitter, it is easy to cause the diameter of the feeding hole drilled by the drill bit 5 to be slightly larger than the diameter of the plugging rod, resulting in the additive flowing out from the gap between the plugging rod and the feeding hole, affecting the feeding effect. At the same time, when driving the mounting plate 3 to move horizontally, the position accuracy is also crucial. Therefore, both the first driving mechanism and the second driving mechanism drive the connecting plate 4 and the mounting plate 3 to displace in the form of a servo motor and a screw rod. Among them, the first driving mechanism includes a servo motor one 11 and a screw rod one 12. The servo motor one 11 is fixed on the support frame 2 and drives the screw rod one 12 to rotate. The screw rod one 12 is threadedly connected to the mounting plate 3; the second driving mechanism includes a servo motor two 13 and a screw rod two 14. The servo motor two 13 is fixed on the mounting plate 3 and drives the screw rod two 14 to rotate. The screw rod two 14 is threadedly connected to the connecting plate 4. By the cooperation of the servo motor and the screw rod, the stability of the movement of the connecting plate 4 and the mounting plate 3 is improved, and no large vibration will occur.

[0031] To further improve the stability of the movement of the connecting plate 4 and the mounting plate 3, a slide rail one 15 is provided at the sliding connection between the mounting plate 3 and the support frame 2. The slide rail one 15 is fixed to the support frame 2, and the mounting plate 3 is slidably matched with the slide rail one 15. At the same time, a slide rail two 16 is provided at the sliding connection between the connecting plate 4 and the mounting plate. The slide rail two 16 is fixed on the mounting plate 3, and the connecting plate 4 is slidably matched with the slide rail two 16. Through the slide rail one 15 and the slide rail two 16, the stability of the movement of the connecting plate 4 and the mounting plate 3 is increased, and the connecting plate 4 and the mounting plate 3 move in the guiding direction of the slide rail one 15 and the slide rail two 16, reducing the deviation or inclination of the connecting plate 4 and the mounting plate 3 during the movement.

[0032] Existing laminators are generally divided into single-layer lamination and multi-layer lamination. When used in a multi-layer laminator, a feeding device needs to be set at each lamination position, which greatly increases the cost. To reduce this cost, a height adjustment mechanism is installed on the frame 1. Through the height adjustment mechanism, the moving platform and the support frame 2 are driven to move along the height direction of the multi-layer laminator. The height adjustment mechanism includes a slide rail three 17, a servo motor three 18, and a lead screw three 19. The support frame 2 is slidably connected to the slide rail three 17 longitudinally installed on the frame 1, and the lead screw three 19 threaded to the support frame 2 is driven to rotate by the servo motor three 18, thereby driving the entire support frame 2 to move up and down.

[0033] To facilitate the disassembly or installation of the drilling structure, the injection gun 7, and the plugging structure, a plurality of mounting holes 20 are provided on the connecting plate 4. The drilling structure, the injection gun 7, and the plugging structure can be fixed on the connecting plate 4 through the cooperation of bolts and the mounting holes 20.

[0034] Working principle:

[0035] S1. When used in a single-layer laminator, the servo motor one 11 drives and the lead screw one 12 rotates, thereby driving the mounting plate 3 and the connecting plate 4, the drilling structure, the injection gun 7, and the plugging structure located on the mounting plate 3 to move horizontally on the support frame 2. When reaching the position where an opening is required, it stops. At this time, the servo motor two 13 drives the lead screw two 14, driving the connecting plate 4 and the drilling structure located on the connecting plate 4 to move towards the foaming board on the laminator. At the same time, the driving motor 6 drives the drill bit 5 to rotate to open a hole in the foaming board. After the hole is opened, then the servo motor two 13 drives the lead screw two 14 to drive the connecting plate 4 and the drilling mechanism to reset, completing the hole drilling operation. Subsequently, the servo motor one 11 drives the mounting plate 3 to move again, aligning the injection gun 7 located on the connecting plate 4 with the injection hole opened in the foaming board. Another servo motor two 13 drives the corresponding connecting plate 4 and the injection gun 7 thereon to move towards the injection hole direction, and the injection gun 7 injects additives, etc. into the injection hole. After the injection, this servo motor two 13 drives the connecting plate 4 and the injection gun 7 to retract, completing the injection operation. Finally, the servo motor one 11 drives the mounting plate 3 to move again, aligning the plugging structure located on the connecting plate 4 with the injection hole of the foaming board. Another servo motor two 13 drives the corresponding connecting plate 4 and the plugging structure thereon to move towards the injection hole direction. The plugging rod in the funnel 8 will fall into the plugging tube 9 under the influence of gravity, and the output end of the electric push rod 10 pushes the plugging rod in the plugging tube 9 into the injection hole. After the plugging, this servo motor two 13 drives the connecting plate 4 and the plugging structure to retract, completing the plugging operation. Then the laminator is started to laminate the foaming board after injection.

[0036] S2. When applied to a multi-layer laminator, by adjusting the position and number of injection holes of the foam board, during injection, first place the foam board on the top or bottom layer of the multi-layer laminator. The general order is from top to bottom or from bottom to top. After placing the foam board, the servo motor three 18 and the lead screw three 19 drive the support frame 2 to move to the side of the foam board. Through the drive of the servo motor one 11 and the rotation of the lead screw one 12, the mounting plate 3 and the connecting plate 4, drilling structure, injection gun 7 and plugging structure located on the mounting plate 3 are driven to move horizontally on the support frame 2 and stop at the position where an opening is required. At this time, the servo motor two 13 drives the lead screw two 14 to drive the connecting plate 4 and the drilling structure located on the connecting plate 4 to move towards the foam board located on the laminator. At the same time, the drive motor 6 drives the drill bit 5 to rotate to open a hole in the foam board. After opening the hole, then the servo motor two 13 drives the lead screw two 14 to drive the connecting plate 4 and the drilling mechanism to reset, completing the hole drilling operation. Subsequently, the servo motor one 11 drives the mounting plate 3 to move again, aligning the injection gun 7 located on the connecting plate 4 with the injection hole opened on the foam board. Another servo motor two 13 drives the corresponding connecting plate 4 and the injection gun 7 thereon to move towards the injection hole direction, and the injection gun 7 injects additives and the like into the injection hole. After the injection is completed, this servo motor two 13 drives the connecting plate 4 and the injection gun 7 to retract, completing the injection operation. Finally, the servo motor one 11 drives the mounting plate 3 to move again, aligning the plugging structure located on the connecting plate 4 with the injection hole of the foam board. Another servo motor two 13 drives the corresponding connecting plate 4 and the plugging structure thereon to move towards the injection hole direction. The plugging rod located in the funnel 8 will fall into the plugging tube 9 under the influence of gravity, and the output end of the electric push rod 10 pushes the plugging rod in the plugging tube 9 into the injection hole. After the plugging is completed, this servo motor two 13 drives the connecting plate 4 and the plugging structure to retract, completing the plugging operation. Then the laminator is started to laminate the foam board after injection. During this injection process, subsequent foam boards can be placed in sequence, and then the above operations are repeated for injection. And so on until all the foam boards on the multi-layer laminator are drilled and the injection, plugging and other processes are completed, and then the laminator laminates the foam board.
