Description

Technical Field

[0001] The utility model relates to the technical field of foam plate processing, in particular to a foam plate injection device. Background Art

[0002] Foam board is a lightweight and porous insulation material. It has been widely used in the construction industry due to its light weight, high strength, thermal insulation, and environmental protection. The production process of foam board usually requires drilling, injection, plugging, and lamination of the foam board.

[0003] Before laminating the existing foam board, it is necessary to drill holes in the foam board with a manual handheld drill, and after drilling, additives such as foaming agent, flame retardant, anti-aging agent, etc. are injected into the foam board, and the injection holes opened on the foam board are blocked. After the above process is completed, the foam board is sent to a laminator for lamination and extruded into shape.

[0004] However, the existing foam board injection method is mostly manual injection with a handheld injection gun. However, since the injection gun is large in size and has a certain weight, it is difficult to directly align and insert it when aligning with the injection hole. Generally, a mechanical arm is installed on the injection gun, and the mechanical arm assists in facilitating manual insertion of the injection gun into the injection hole for injection, or the injection gun is lifted by a lifting rope to reduce part of the weight of the injection gun, and then the injection gun is driven manually to inject. However, the assistance of the mechanical arm and the lifting rope are only auxiliary functions, which only reduce the weight of the injection gun and facilitate manual movement of the injection gun. After a long period of injection, workers still need to consume a lot of physical strength. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: See Figures 1 to 5According to an embodiment of the utility model, a technical solution is provided: a foam board injection device, comprising: an injection gun 1, the injection gun 1 comprises a feed port 101 and a gun head 102, the additive can enter the injection gun 1 along the feed port 101 and be sprayed out by the injection gun 1 along the gun head 102, and also comprises a frame 2 installed on one side of the laminator, a track 3 is installed on the frame 2, a connecting plate 4 is slidably connected to the track 3, the injection gun 1 is installed on the connecting plate 4, the gun head 102 faces the laminator and protrudes from the connecting plate 4, a driving mechanism is installed on the frame 2, and the driving mechanism can push the connecting plate 4 to move back and forth toward the laminator. It should be noted that the driving mechanism can be an electric push rod, which is fixed on the frame 2, and its output end pushes the connecting plate 4 to slide on the track 3; it can also be a screw motor, the main body of the screw motor is fixed on the frame 2, and its screw end is threadedly connected to the connecting plate 4, or the servo motor drives the screw to drive the connecting plate 4 to slide on the track 3, etc.

[0027] The foam board injection device adopts the above-mentioned structure, by installing the frame 2 on the laminator and placing the foam board in the laminator, and because the positions of the injection holes of the foam boards are almost the same, at this time, the connecting plate 4 is driven by the driving structure to slide on the track 3, so that the injection gun 1 located on the connecting plate 4 moves toward the foam board, and the gun head 102 of the injection gun 1 is inserted into the injection hole of the foam board to inject and fill the foam board. The weight of the injection gun 1 of this structure is supported by the frame 2 and the connecting plate 4, and the connecting plate 4 is driven by the driving mechanism to drive the injection gun 1 to inject the injection holes of the foam board, so that there is no need to manually hold the injection gun 1 for injection, which solves the problem that the existing injection requires manual driving of the injection gun 1 to move, which consumes a lot of physical strength of workers and has low efficiency.

[0028] In this embodiment, in the process of driving the connecting plate 4 to move by various driving modes, such as an electric push rod or a screw motor, the driving mode in which the first servo motor 5 drives the first screw rod 6 can improve the response speed and stability without generating large vibrations. For this purpose, the driving structure is set to drive the connecting plate 4 to slide by the first servo motor 5 and the first screw rod 6.

[0029] In this embodiment, the length of the foaming board is proportional to the number of injection holes on one side of the length of the foaming board. When the foaming board is long, multiple pouring holes need to be injected. Therefore, there are some defects and it is impossible to inject materials into the longer foaming board. For this reason, a first displacement mechanism is provided on the frame 2. The first displacement mechanism drives the connecting plate 4 to move along the length direction of the foaming board (i.e., the horizontal direction) to inject materials into multiple pouring holes on one side of the foaming board. The first displacement mechanism includes a support frame 7, a track 8, a mounting plate 9, a second servo motor 10 and a first servo motor 11. Two screw rods 11, wherein the second servo motor 10 drives the second screw rod 11 to rotate, and the second screw rod 11 is threadedly connected to the mounting plate 9. When the second servo motor 10 drives the second screw rod 11 to rotate, the mounting plate 9 is driven to move on the track 2 8, and the connecting plate 4 and the injection gun 1 and the driving mechanism located on the mounting plate 9 move together with the mounting plate 9. It should be noted that a longer hose needs to be installed on the injection gun 1, and the additive can be injected into the injection gun 1 through the hose, so that the injection gun 1 will not affect the injection when it moves to the other side of the frame 2.

[0030] In this embodiment, in order to facilitate installation and disassembly, a plurality of connecting holes 12 are provided on the mounting plate 9, so that the injection gun 1 can be installed on the mounting plate 9 by the cooperation of bolts and the connecting holes 12, and other structures such as a drilling gun and a plugger can also be installed on the mounting plate 9.

[0031] In this embodiment, the existing laminating machine is usually divided into single-layer lamination and multi-layer lamination. When used in a multi-layer laminating machine, it is necessary to set an injection gun 1 at each lamination location, which greatly increases the cost. In order to reduce the cost, a second displacement mechanism is installed on the frame 2. Through the second displacement mechanism, the first displacement mechanism and other structures located on the first displacement mechanism are driven to move along the height direction of the multi-layer laminating machine. The second displacement mechanism includes a track three 13, a third servo motor 14 and a third screw rod 15. The support frame 7 of the second displacement mechanism is slidably connected to the track three 13 longitudinally installed on the frame 2, and the third screw rod 15 threadedly connected to the support frame 7 is driven to rotate by the third servo motor 14, thereby driving the entire second displacement mechanism to move up and down.

[0032] In this embodiment, considering the weight of the second displacement mechanism and the injection gun 1, relying solely on the threaded connection between the third screw rod 15 and the support frame 7 is prone to thread slippage or hole expansion at the thread of the support frame 7, thereby reducing the service life. Therefore, a support block 16 and a threaded tube 17 are provided at the threaded connection between the third screw rod 15 and the support frame 7. The support block 16 is fixed to the threaded tube 17 and the threaded tube 17 is fixed to the support frame 7. When the third servo motor 14 drives the third screw rod 15 to rotate, the threaded tube 17 is driven to move up and down, and the support frame 7 is supported by the support block 16 due to gravity. After damage, only the support block 16 and the threaded tube 17 need to be replaced, without replacing the support frame 7, thereby reducing maintenance costs.

[0033] Working principle:

[0034] S1. When used on a single-layer laminator, since the positions of the injection holes of the same batch of foam boards are almost the same, during injection, the second servo motor 10 drives the second screw 11 to rotate, driving the mounting plate 9 to move horizontally on the track 8. When moving to the corresponding injection hole position, the first servo motor 5 located on the mounting plate 9 drives the first screw 6 to rotate, driving the connecting plate 4 to slide on the track 3, and then the gun head 102 of the injection gun 1 is inserted into the injection hole to inject the additive into the foam board. After the injection is completed, the first servo motor 5 drives the first screw 6 to drive the connecting plate 4 to reset, and the second servo motor 10 drives the mounting plate 9 to move again to inject the subsequent injection holes on the foam board. When the thickness of the foam board is different and the height of the injection hole is different, the height of the first displacement mechanism can also be adjusted by the second displacement mechanism;

[0035] S2. When used on a multi-layer laminating machine, by adjusting the position and number of the injection holes of the foam board, when injecting, the foam board is first placed on the top layer or bottom layer of the multi-layer laminating machine, and the order is generally from top to bottom or from bottom to top. After the foam board is placed, the third servo motor 14 and the third screw rod 15 drive the first displacement mechanism to move to the side of the foam board, and the second servo motor 10 drives the second screw rod 11 to rotate, driving the mounting plate 9 to move horizontally on the track 2 8. When moving to the injection hole, the first servo motor 5 located on the mounting plate 9 drives the first screw rod 6 to rotate. Rotate, thereby driving the connecting plate 4 to slide on the track 3, and then the gun head 102 of the injection gun 1 is inserted into the injection hole to inject the additive into the foam board. After the injection is completed, the first servo motor 5 drives the first screw 6 to drive the connecting plate 4 to reset, and the second servo motor 10 drives the mounting plate 9 to move again to inject material into the subsequent injection holes on the foam board. During this injection process, the subsequent foam boards can be placed in sequence, and then the above operation is repeated to drill holes, and so on until the foam boards on the multi-layer laminating machine are drilled and the injection, blocking and other processes are completed, and the laminating machine laminates the foam boards.
