[0002] Polypropylene foam sheets are widely used in automotive bumper liners, precision instrument packaging, and other fields due to their lightweight, impact resistance, and heat insulation properties. In actual production, due to the limited size of the foaming mold, EPP sheets need to be spliced ​​to form large-format structural components.

[0003] In the existing technology, when applying adhesive to the joint surface of the boards, it is necessary to apply adhesive to two polypropylene foam boards to be spliced ​​in sequence and place them on the processing table for alignment and splicing. This feeding and processing method is inefficient and not convenient for large-scale continuous processing.

[0004] In view of this, we propose an automatic splicing device for polypropylene foam boards. Utility Model Content

[0029] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figure 1-5 This utility model provides a technical solution:

[0032] An automatic splicing device for polypropylene foamed sheets includes a frame 1 and a worktable 11 fixedly connected to the frame 1. It also includes a feeding assembly 2, an adhesive application assembly 3, and a discharging assembly 4. The feeding assembly 2 includes a movable plate 22 slidably connected to the frame 1. Polypropylene foamed sheets to be spliced ​​are placed on both sides of the movable plate 22. The feeding assembly 2 is used to feed polypropylene foamed sheets from both sides of the worktable 11. The adhesive application assembly 3 includes a movable block 32 slidably connected to the top of the frame 1 and a double-headed glue gun 36 capable of moving up and down along the movable block 32. The adhesive application assembly 3 is used to apply adhesive to the opposite surfaces of the two polypropylene foamed sheets to be spliced. The discharging assembly 4 includes a first limiting plate 41 slidably connected horizontally to the worktable 11 and a second limiting plate 43 slidably connected vertically to the worktable 11. The discharging assembly 4 is used to move the spliced ​​polypropylene foamed sheets out of the processing position for discharging.

[0033] In other words, the feeding component 2 is used to feed two polypropylene foam boards at the same time, while the gluing component 3 applies a coating to the two polypropylene foam boards at the same time. During the actual processing, the two pusher plates 27 complete the bonding of the two polypropylene foam boards after gluing. After the bonding and splicing are completed, the unloading component 4 completes the unloading, thus forming a continuous processing.

[0034] Secondly, the feeding assembly 2 also includes a first electric push rod 21 fixedly connected to the frame 1 and two mounting brackets 25 fixedly connected to both sides of the frame 1. The extended end of the first electric push rod 21 is fixedly connected to the bottom of the movable plate 22. A second electric push rod 26 is fixedly connected to each of the two mounting brackets 25. The extended end of the second electric push rod 26 is fixedly connected to a pusher plate 27 for pushing the polypropylene foam board from the movable plate 22 to the worktable 11. With this configuration, the movable plate 22 is vertically raised and lowered by the first electric push rod 21 to adjust its height, so that the working surface of the movable plate 22 is precisely aligned with the plane of the worktable 11. Then, the pusher plate 27 is pushed horizontally by the second electric push rods 26, which are independently controlled on both sides. The lifting height of the first electric push rod 21 each time is the same as the height of the polypropylene foam board to be spliced. After the pusher plate 27 pushes and splices the two polypropylene foam boards after the glue has been applied, it still needs to be held for a period of time to allow the glue to take effect, so as to ensure the bonding and splicing effect.

[0035] Furthermore, multiple first sliders 23 with T-shaped cross sections are fixedly connected to the movable plate 22, and multiple first slide grooves 24 adapted to the size of the first sliders 23 are provided on the frame 1. The arrangement of the first sliders 23 and the first slide grooves 24 enables the movable plate 22 to slide stably along the vertical track during the lifting process, thereby improving the stability of the feeding operation.

[0036] Specifically, a horizontally arranged third electric push rod 31 is fixedly connected to the top of the frame 1. The extended end of the third electric push rod 31 is fixedly connected to the movable block 32. A vertically arranged fourth electric push rod 33 is fixedly connected to the movable block 32. The extended end of the fourth electric push rod 33 is fixedly connected to the double-headed glue gun 36. Two second sliders 34 with a T-shaped cross-section are fixedly connected to both sides of the movable block 32. Two second slide grooves 35 with sizes adapted to the second sliders 34 are opened on the top of the frame 1. The second sliders 34 and the second slide grooves 35 are used to ensure the stability of the movable block 32 when it moves. The third electric push rod 31 and the fourth electric push rod 33 are used to enable the double-headed glue gun 36 to adapt to more production and processing needs. The double-headed glue gun 36 is a relatively mature existing technology and can be purchased directly on the market.

[0037] Furthermore, a horizontally arranged fifth electric push rod 42 is fixedly connected to the workbench 11, and the extended end of the fifth electric push rod 42 is fixedly connected to the first limiting plate 41. A vertically arranged sixth electric push rod 44 is fixedly connected to the frame 1, and the extended end of the sixth electric push rod 44 is fixedly connected to the bottom of the second limiting plate 43. The top surface of the second limiting plate 43 is higher than the table surface of the workbench 11 in the initial state. It is used to cooperate with the movable first limiting plate 41 to align the two polypropylene foam boards to ensure splicing accuracy. During material feeding, the second limiting plate 43 descends with the sixth electric push rod 44, and the fifth electric push rod 42 drives the first limiting plate 41 to push the spliced ​​polypropylene foam board out of the processing area.

[0038] In addition, two guide plates 28 are fixedly connected to both sides of the workbench 11 to guide the polypropylene foam board in conjunction with the feeding component 2. The guide plates 28 are arranged in a trumpet shape at the feeding channel so that they can automatically correct the angular deviation during the board pushing process and limit the lateral shaking of the board, so as to ensure that the two boards to be spliced ​​can be initially aligned when they enter the workbench 11, and then further aligned by the first limiting plate 41.

[0039] Working principle:

[0040] During processing, the movable plate 22 is raised to the height of the worktable 11 by the first electric push rod 21. At this time, the pre-placed boards to be spliced ​​on both sides are constrained by the guide plates 28. The second electric push rods 26 on both sides simultaneously push the push plate 27 to push the two boards horizontally into the worktable 11, so that the joint surfaces of the boards are close to each other. Then, the movable block 32, driven by the third electric push rod 31, moves horizontally to above the joint with the double-headed glue gun 36. The fourth electric push rod 33 moves down to make the glue gun nozzle accurately close to the joint surface of the boards. At the same time, the double-headed glue gun 36 starts and moves along the joint to apply glue to the inner end faces of the two boards simultaneously. After the adhesive is applied, the push plates 27 on both sides continue to push towards each other until the two boards are completely bonded. At this time, the second limiting plate 43 serves as a vertical reference plane for auxiliary positioning, and the first limiting plate 41 extends horizontally to adjust the position of the boards to ensure precise alignment of the joints. The adhesive is initially cured under constant pressure maintained by the push plates 27. Then, the sixth electric push rod 44 drives the second limiting plate 43 to descend and detach from the bottom of the board. The fifth electric push rod 42 immediately pushes the first limiting plate 41 to push the spliced ​​finished product horizontally away from the workbench 11 to the unloading area. The movable plate 22 rises with the first electric push rod 21 to perform splicing processing on the subsequent boards.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
