Technical Field

[0001] The utility model relates to the technical field of sheet machines, in particular to a structural double-layer co-extrusion sheet machine. Background Art

[0002] Plastic packaging sheets are mainly used for producing thermoformed products such as disposable plastic cups, plates, bowls, dishes, boxes, etc., and are widely used in the packaging of food, vegetables, fruits, beverages, dairy products, industrial parts and other fields. With the increasing demand, the uses of packaging plastic thermoformed sheets are becoming more and more extensive, and the consumption is also increasing year by year;

[0003] In the production process of double-layer co-extrusion sheets by traditional equipment, the situation of uneven material pressing may occur, which will lead to unstable product quality and affect production efficiency. In some equipment, the movement of the top plate may not be smooth enough, resulting in uneven contact between the side surface and the bottom of the material, thus affecting the final processing effect of the material. Moreover, in the prior art, adjusting the position of the top plate may have problems such as complex operation or insufficient precision, which will affect the pressing quality and production efficiency of the material. In view of this, we propose a structural double-layer co-extrusion sheet machine to solve the existing problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a structural double-layer co-extrusion sheet machine to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a structural double-layer co-extrusion sheet machine, including a base, a mounting frame, a pressing mechanism, a top-up mechanism and a workbench. On one side of the base, there is a fixed connection with a mounting frame. There are two groups of symmetrically arranged mounting frames, and a pressing mechanism is arranged between the mounting frames. On one side of the mounting frame on the base, there is a fixed connection with a workbench, and a top-up mechanism driven by gears is arranged inside the workbench on the base;

[0006] The pressing mechanism includes a first telescopic cylinder, a driving rod, a transmission member, a connecting member, a lower pressing plate and a fixed rod. On one side inside the mounting frame, there are symmetrically arranged first telescopic cylinders. The output end of the first telescopic cylinder is movably connected with a driving rod, and a fixed rod is fixedly connected between the mounting frames. The driving rod is located on the fixed rod, and the end of the driving rod away from the first telescopic cylinder is movably connected with a transmission member.

[0007] Preferably, a lower pressing plate is slidably connected to one side of the mounting frame. The side of the transmission member away from the driving rod is movably connected with a connecting member, and the upper side of the lower pressing plate is fixedly connected with the connecting member. The position between the lower pressing plate and the workbench is matched with each other.

[0008] Preferably, the upper pressing mechanism includes a first rotating rod, a transmission plate, a limiting top plate, a first synchronous pulley, a synchronous belt, a driving motor, a limiting frame, a second synchronous pulley, a second rotating rod, a second telescopic cylinder and a top plate.

One side of the transmission plate is fixedly connected to a limiting top plate. A first rotating rod is movably connected between the sliding frames. A first synchronous pulley is arranged in the middle of the first rotating rod. And first transmission wheels are fixedly connected to both sides of the first rotating rod. The lower surface of the transmission plate has a rack structure. Gears between the transmission plate and the first transmission wheels are meshed with each other.

[0009] Preferably, a second rotating rod is movably connected inside the base. A second synchronous pulley is fixedly connected to the middle of the second rotating rod.

And a driving rod is movably connected below the limiting frames. And a slide rail is fixedly connected inside the base. A transmission rack is slidably connected to the slide rail. One side of the transmission rack is movably connected to the driving rod. Gears between the transmission rack and the second transmission wheels are meshed with each other.

[0011] Preferably, gaskets are arranged on the surfaces of the limiting top plate, the top plate and the lower pressing plate. The gaskets are made of rubber materials. And a second telescopic cylinder is fixedly connected to one side of the limiting frame inside the workbench. The output end of the second telescopic cylinder is fixedly connected to the top plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. When the first telescopic cylinder is started, the driving rod moves up and down on the fixed rod along with the expansion and contraction of the cylinder. The movement of the driving rod drives the connecting piece through the transmission piece, and then pushes the lower pressing plate to press down on the material on the workbench. The lower pressing plate moves smoothly under the sliding connection of the mounting frame, and cooperates with the workbench to realize the uniform pressing of the material, ensuring that the material can be uniformly pressed during the production of double-layer co-extruded sheets, thereby improving the production quality and efficiency.

[0015] 3. The top plate is connected to the limiting frame and the driving rod. The sliding of the limiting frame drives the driving rod to drive the top plate to move up and down through the transmission rack. The slide rail and the transmission rack ensure the stable movement of the top plate, and the output end of the second telescopic cylinder can also adjust the position of the top plate.

[0016] The device realizes the uniform pressing of materials through the pressing mechanism. The stable movement of the lower pressing plate ensures the uniform pressing of materials in the production of double-layer co-extruded sheets, improving the production quality and efficiency. Moreover, through the linkage of the limiting frame and the driving rod in the upward pushing mechanism, it ensures the smooth contact of the side surface of the material and the contact at the bottom of the material, thereby further optimizing the production process.

It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0025] As Figure 1-6 shown, a structural double-layer coextrusion sheet machine proposed by the present utility model includes a base 1, a mounting frame 2, a downward pressing mechanism 3, an upward pushing mechanism 4 and a workbench 5.

[0028] When the first telescopic cylinder 301 is started, the driving rod 302 moves up and down on the fixing rod 306 as the cylinder expands and contracts. The movement of the driving rod 302 drives the connecting member 304 through the transmission member 303, and then pushes the lower pressing plate 305 to press down on the material on the workbench 5. The lower pressing plate 305 moves smoothly under the sliding connection of the mounting frame 2 and cooperates with the workbench 5 to achieve uniform downward pressing of the material, ensuring that in the production of double-layer coextrusion sheets, the material can be uniformly pressed, thereby improving the production quality and efficiency.

[0032] The driving motor 406 drives the second rotating rod 414 to rotate through the output end.

The transmission plate 402 moves on its sliding frames 417 following the rotation of the first rotating rod 401, so that one side of the limiting top plate is mutually attached to the side surface of the material of the workbench 5;

[0033] Meanwhile, the top plate 416 is connected through the limiting frames 407 and the driving rod 410. The sliding of the limiting frames 407 drives the driving rod 410 to drive the top plate 416 to move up and down through the transmission rack 411. The slide rail 412 and the transmission rack 411 ensure the smooth movement of the top plate 416. And the output end of the second telescopic cylinder 415 can also adjust the position of the top plate 416.

[0034] In an optional embodiment, gaskets are provided on the surfaces of the limit top plate 403, the top plate 416 and the lower pressing plate 305. The gaskets are made of rubber material. And inside the workbench 5, a second telescopic cylinder 415 is fixedly connected to one side of the limit frame 407, and the output end of the second telescopic cylinder 415 is fixedly connected to the top plate 416.

[0035] The working principle of the present utility model is as follows: when using this device, when the first telescopic cylinder 301 is started, the driving rod 302 moves up and down along the fixed rod 306 with the expansion and contraction of the cylinder. The movement of the driving rod 302 drives the connecting piece 304 through the transmission member 303, and then pushes the lower pressing plate 305 to press down on the material on the workbench 5. The lower pressing plate 305 moves smoothly under the sliding connection of the mounting frame 2, and cooperates with the workbench 5 to realize the uniform pressing of the material, ensuring that in the production of double-layer co-extruded sheets, the material can be uniformly pressed, thereby improving the production quality and efficiency. The driving motor 406 drives the second rotating rod 414 to rotate through the output end. The second synchronous pulley 413 on the second rotating rod 414 is connected to the first synchronous pulley 404 through the synchronous belt 405. The transmission plate 402 slides on the base 1 through the sliding frame 417, and the rack below the transmission plate 402 meshes with the gear of the first transmission wheel 408. The transmission plate 402 moves on its sliding frame 417 with the rotation of the first rotating rod 401, so that one side of the limit top plate is mutually attached to the side surface of the material on the workbench 5;

[0036] At the same time, the top plate 416 is connected through the limit frame 407 and the driving rod 410. The sliding of the limit frame 407 drives the driving rod 410 to drive the top plate 416 to move up and down through the transmission rack 411. The slide rail 412 and the transmission rack 411 ensure the smooth movement of the top plate 416, and the output end of the second telescopic cylinder 415 can also adjust the position of the top plate 416. This device realizes the uniform pressing of the material through the pressing mechanism 3. The stable movement of the lower pressing plate 305 ensures the uniform pressing of the material in the production of double-layer co-extruded sheets, improves the production quality and efficiency, and through the linkage of the limit frame 407 and the driving rod 410 in the upper pressing mechanism 4, it ensures the smooth contact of the side surface of the material and the contact of the bottom of the material, thereby further optimizing the production process.
