Description

Technical Field

[0001] This utility model relates to the field of EVA film bonding devices, and more particularly to a pressure-adjustable EVA film bonding device. Background Technology

[0002] EVA film bonding equipment refers to equipment that uses a hot pressing process to laminate ethylene-vinyl acetate (EVA) film onto the surface of a substrate. Its core is to melt and bond EVA through controlled temperature and pressure. The pressure adjustable hot press is a type of this equipment. It dynamically adjusts the pressure of the hot press plate through a drive device to adapt to the processing requirements of different thicknesses and materials, ensuring bonding strength and yield.

[0003] Existing technologies, such as the utility model patent with publication number CN217752405U, disclose a hot-pressing molding device for producing EVA anti-slip mats. This patent includes a device body, a controller, and two flip doors. The controller is fixedly connected to the right side of the device body, and the two flip doors are movably connected to the top and bottom of the front side of the device body via rotating shafts. Grooves are provided on both sides of each flip door, and housings are provided on both sides of each flip door. A through hole is provided on the left side of each housing, and a through groove is provided on the top of each housing. By using the grooves, housings, through holes, through grooves, positioning components, control components, and a handle in conjunction, pressing down on the first transmission column causes it to move downwards along the rotating shaft. This causes the first transmission column to drive the positioning column to move to the right via the second transmission column. Simultaneously, as the positioning column disengages from the groove cavity, it compresses the spring. This solves the problem that in existing devices, the flip doors cannot be reliably fixed to the front side of the device body after long-term use, thus affecting the user.

[0004] The inventors discovered the following problems in the use of the EVA film bonding device during their daily work: users need to put their hands under the hot press plate to load and unload the material frame, which is unsafe; when the equipment is working on the EVA film in the material frame, users need to wait for a lot of time, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low work efficiency and low operational safety.

[0006] To solve the above technical problems, this utility model provides a pressure-adjustable EVA film bonding device, comprising: a base, a worktable fixedly connected to the upper surface of the base, a driving device fixedly connected to the upper surface of the worktable, a hot press plate fixedly connected to the output end of the driving device, a control box fixedly connected to one side of the base, an adjustment structure provided on the upper surface of the worktable, the adjustment structure including a support plate, the support plate being fixedly connected to the worktable, an adjustment groove formed on the upper surface of the support plate, the inner wall of the adjustment groove communicating with two storage grooves, a round rod slidably connected to the inner wall of both the storage groove and the adjustment groove, an installation frame fixedly connected to the upper end of the round rod, and the installation frame... Two mounting slots are provided on both sides. Mounting blocks are slidably connected to the inner walls of both mounting slots. Material frames are fixedly connected to the upper surfaces of the two mounting blocks. Two mounting rods are slidably connected to the inner walls of the mounting frames. The ends of the two mounting rods that are far apart from each other are engaged with the mounting blocks. Springs are fixedly connected to the sides of the two mounting rods that are close to each other. The ends of the springs that are far away from the mounting rods are fixedly connected to the mounting frames. A positioning frame is slidably connected to the inner wall of the adjusting slot. A connecting rod is fixedly connected to the side of the positioning frame that is far away from the worktable. The surface of the connecting rod is slidably connected to the support plate. A handle is rotatably connected to the end of the connecting rod that is far away from the positioning frame. Two positioning plates are fixedly connected to the upper surface of the support plate.

[0007] The above-mentioned components achieve the following effects: the two material frames can work alternately with the help of the storage slot and the adjustment slot, and the material can be loaded outside the hot press plate area, which improves work efficiency and operational safety.

[0008] Preferably, a lever plate is fixedly connected to the surface of the mounting rod, and the lever plate is a rectangular plate.

[0009] The effect achieved by the above components is that the rectangular lever provides a larger force application area, making it easier for the operator to press the mounting rod inward to release the material frame.

[0010] Preferably, the ends of the two mounting rods that are far apart from each other are arc-shaped.

[0011] The effect achieved by the above components is that the arc-shaped design at the end of the mounting rod facilitates the sliding of the mounting rod into the mounting block.

[0012] Preferably, the two positioning plates have rounded corners at the ends near the storage slots.

[0013] The effect achieved by the above components is that the rounded corner design at the end of the positioning plate can prevent sharp collisions or jamming between the mounting frame and the end of the positioning plate during the process of the material frame sliding from the storage groove to the adjustment groove, making the sliding transition of the material frame smoother and more seamless.

[0014] Preferably, an auxiliary structure is provided on one side of the base. The auxiliary structure includes an auxiliary frame, which is fixedly connected to the base. An auxiliary rod is threadedly inserted into the surface of the auxiliary frame. A mating plate is slidably connected to the inner wall of the auxiliary frame. The mating plate engages with the arc surface of the auxiliary rod. A truck is fixedly connected to the lower surface of the mating plate.

[0015] The effect achieved by the above components is as follows: the docking plate is fixed in the auxiliary frame by the auxiliary rod, thereby fixing the truck next to the base. The user can use the truck to collect and transport the workpiece, which facilitates user management and improves work efficiency.

[0016] Preferably, a plurality of anti-slip protrusions are fixedly connected to the end of the auxiliary rod away from the auxiliary frame, and the plurality of anti-slip protrusions are evenly distributed on the auxiliary rod.

[0017] The effect achieved by the above components is that the anti-slip protrusions at the end of the auxiliary rod significantly increase the friction between the operator's hand and the rod, making it easier for the user to rotate the auxiliary rod.

[0018] Preferably, a limiting frame is fixedly connected to the surface of the auxiliary frame at the position corresponding to the auxiliary rod, and the cross-section of the limiting frame is "L" shaped.

[0019] The effect achieved by the above components is to limit the movement distance of the auxiliary rod by using the limit frame to prevent the auxiliary rod from detaching from the auxiliary frame and being lost.

[0020] Compared with related technologies, the pressure-adjustable EVA adhesive film bonding device provided by this utility model has the following beneficial effects:

[0021] By setting an adjustment structure, the material frame can be easily slidably switched between the hot pressing station (in the adjustment groove) and the preparatory station (in the storage groove), and the material frame can be precisely positioned in the hot pressing station. In specific operation, the loaded material frame is pushed from the storage groove into the positioning frame of the adjustment groove, and the rod is rotated and pushed to accurately send the material frame under the hot pressing plate for operation. At the same time, during the hot pressing operation, the loading operation can be performed on the material frame in the preparatory station, which significantly improves the equipment utilization rate and operation efficiency. Since it is not necessary to operate under the hot pressing plate, the operation safety is improved. When it is necessary to change different material frames, press the mounting rod inward to compress the spring, release the locking of the mounting block, and then lift the material frame upward for replacement. The operation is simple and quick. The two positioning plates guide and limit the moving mounting frame, ensuring that the material frame moves smoothly and is positioned accurately.

[0022] By setting up an auxiliary structure and using auxiliary rods to fix the docking plate inside the auxiliary frame, the truck can be fixed next to the base. Users can use the truck to collect and transport workpieces, which facilitates user management and improves work efficiency. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 The present invention provides a pressure-adjustable EVA adhesive film bonding device, comprising: a base 1, a workbench 2 fixedly connected to the upper surface of the base 1, a drive device 3 fixedly connected to the upper surface of the workbench 2, a hot press plate 4 fixedly connected to the output end of the drive device 3, a control box 5 fixedly connected to one side of the base 1, an adjustment structure 6 provided on the upper surface of the workbench 2, and an auxiliary structure 7 provided on one side of the base 1.

[0032] In the embodiments of this utility model, please refer to Figures 1 to 4The adjustment structure 6 includes a support plate 601, which is fixedly connected to the worktable 2. An adjustment groove 602 is formed on the upper surface of the support plate 601. The inner wall of the adjustment groove 602 is connected to two storage grooves 603. A round rod 604 is slidably connected to both the inner wall of one storage groove 603 and the inner wall of the adjustment groove 602. A mounting frame 605 is fixedly connected to the upper end of the round rod 604. Two mounting grooves 606 are formed on both sides of the mounting frame 605. Mounting blocks 607 are slidably connected to the inner walls of both mounting grooves 606. The upper surfaces of the two mounting blocks 607... A material frame 608 is fixedly connected to the surface of the mounting frame 605. Two mounting rods 609 are slidably connected to the inner wall of the mounting frame 605. The ends of the two mounting rods 609 that are far apart from each other are engaged with the mounting block 607. Springs 610 are fixedly connected to the sides of the two mounting rods 609 that are close to each other. The ends of the springs 610 that are far away from the mounting rods 609 are fixedly connected to the mounting frame 605. A positioning frame 612 is slidably connected to the inner wall of the adjusting groove 602. A connecting rod 613 is fixedly connected to the side of the positioning frame 612 that is far away from the worktable 2. The surface of the connecting rod 613 is flush with the support plate 607. 1. A sliding connection is established, with a handle 614 rotatably connected to the end of the connecting rod 613 away from the positioning frame 612. Two positioning plates 615 are fixedly connected to the upper surface of the support plate 601. The two material frames 608 can be operated alternately using the storage groove 603 and the adjustment groove 602. Material can be loaded outside the area of ​​the hot press plate 4, improving work efficiency and operational safety. A lever 611 is fixedly connected to the surface of the mounting rod 609. The lever 611 is a rectangular plate, which provides a larger force application area, allowing the operator to press the mounting rod 609 inward. 9. To make it easier to release the material frame 608, the ends of the two mounting rods 609 that are far apart from each other are arc-shaped. The arc-shaped design of the ends of the mounting rods 609 facilitates the sliding of the mounting rods 609 into the mounting block 607. The ends of the two positioning plates 615 near the storage groove 603 are provided with rounded corners. The rounded corner design of the ends of the positioning plates 615 can prevent the mounting frame 605 from sharply colliding or jamming with the ends of the positioning plates 615 during the process of the material frame 608 sliding from the storage groove 603 to the adjustment groove 602, making the sliding transition of the material frame 608 smoother and more seamless.

[0033] In the embodiments of this utility model, please refer to Figure 5The auxiliary structure 7 includes an auxiliary frame 71, which is fixedly connected to the base 1. An auxiliary rod 72 is threadedly inserted into the surface of the auxiliary frame 71. A mating plate 73 is slidably connected to the inner wall of the auxiliary frame 71, and the mating plate 73 engages with the arc surface of the auxiliary rod 72. A cart 74 is fixedly connected to the lower surface of the mating plate 73. The auxiliary rod 72 is used to fix the mating plate 73 inside the auxiliary frame 71, thereby fixing the cart 74 next to the base 1. The user uses the cart 74 to collect and transport workpieces, which facilitates user management and improves work efficiency. The auxiliary rod 72 has several anti-slip protrusions fixedly connected to one end away from the auxiliary frame 71. The anti-slip protrusions are evenly distributed on the auxiliary rod 72. The anti-slip protrusions at the end of the auxiliary rod 72 significantly increase the friction between the operator's hand and the rod, making it easier for the user to rotate the auxiliary rod 72. A limit frame 75 is fixedly connected to the surface of the auxiliary frame 71 at the position corresponding to the auxiliary rod 72. The cross-section of the limit frame 75 is "L" shaped. The limit frame 75 is used to limit the movement distance of the auxiliary rod 72, preventing the auxiliary rod 72 from detaching from the auxiliary frame 71 and being lost.

[0034] The working principle of the pressure-adjustable EVA adhesive film bonding device provided by this utility model is as follows: By setting the adjustment structure 6, the material to be bonded is first placed in the material frame 608. After the material loading operation is completed, the material frame 608 is pushed from the storage groove 603 into the adjustment groove 602. During this process, the material frame 608, the mounting frame 605, and the round rod 604 slide along the inner wall of the storage groove 603 and the adjustment groove 602 as a whole. The round rod 604 moves into the positioning frame 612 in the adjustment groove 602. Then, the handle 614 is rotated upward to the horizontal position and pushed towards the worktable 2. The handle 614 drives the connecting rod 613 and the positioning frame 612 to move. The positioning frame 612 moves the round rod 604, causing the loaded material frame 608 to move along the adjusting groove 602 to the worktable 2 and directly below the hot press plate 4. During this process, the two positioning plates 615 limit the two sides of the mounting frame 605, and the material frame 608 slides along the upper surface of the two positioning plates 615. Then the equipment can be started to perform EVA film pasting. While waiting, the user can load the unloaded material frame 608 on the support plate 601. After the hot press plate 4 has finished operating, pull the lever 614 away from the worktable 2. The lever 614 drives the positioning frame 612 to move through the connecting rod 613. 612 then drives the round rod 604 to move the material frame 608 away from the worktable 2. When the positioning frame 612 is obstructed, the material frame 608 is moved from the position of the adjusting groove 602 to the storage groove 603. Similarly, another loaded material frame 608 is moved to the adjusting groove 602. The operating lever 614 sends the loaded material frame 608 directly under the hot press plate 4. When it is necessary to replace the material frame 608 as needed, first operate the two mounting rods 609 on the mounting frame 605. Move the two mounting rods 609 towards each other. The spring 610 is in a compressed state, and the mounting rods 609 gradually move away from the mounting block 607, releasing the mounting block 607. The limit is reached, at which point the material frame 608 can be moved upward, so that the mounting block 607 moves upward away from the mounting groove 606 on the mounting frame 605. The rectangular lever 611 provides a large force application area, making it easier for the operator to press the mounting rod 609 inward to release the material frame 608. The arc-shaped design at the end of the mounting rod 609 facilitates the sliding of the mounting rod 609 into the mounting block 607. The rounded corner design at the end of the positioning plate 615 can prevent sharp collisions or jamming between the mounting frame 605 and the end of the positioning plate 615 during the process of the material frame 608 sliding from the storage groove 603 to the adjustment groove 602, making the sliding transition of the material frame 608 smoother and more seamless.

[0035] By setting up the auxiliary structure 7, the auxiliary rod 72 is first rotated. The auxiliary rod 72 moves away from the worktable 2 along the auxiliary frame 71 with the help of the thread. After the auxiliary rod 72 moves away from the inner wall area of ​​the auxiliary frame 71, the truck 74 is moved so that the docking plate 73 on the truck 74 moves into the auxiliary frame 71. The auxiliary rod 72 is rotated in the opposite direction. The auxiliary rod 72 moves closer to the worktable 2 with the help of the thread. The auxiliary rod 72 is inserted into the docking plate 73, so that the position of the truck 74 is fixed next to the base 1. The anti-slip protrusion at the end of the auxiliary rod 72 significantly increases the friction between the operator's hand and the rod, making it easier for the user to rotate the auxiliary rod 72. The movement distance of the auxiliary rod 72 is limited by the limit frame 75 to prevent the auxiliary rod 72 from falling off the auxiliary frame 71 and being lost.

[0036] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
