Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a cling film roll-up and edge-pressing cutting machine. Background Technology

[0002] Plastic wrap is an everyday product used to seal food to reduce the contact between food and oxygen in the air. It can slow down the oxidation and spoilage process of food, effectively extend the shelf life of food, and maintain the moisture and freshness of food. After the plastic wrap is produced, it needs to be rolled up, and before rolling it up, the excess uneven parts on both sides of the plastic wrap need to be cut off.

[0003] Currently, the edge-pressing and cutting machine used before rolling up cling film has an inconveniently adjustable spacing between the cutting blades used to cut excess side edges, making it unsuitable for cutting the side edges of cling film of different widths. Therefore, we propose a cling film rolling edge-pressing and cutting machine. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic wrap rolling edge pressing and cutting machine, which has the advantages of being able to cut off the excess edges on both sides of the plastic wrap before rolling and is applicable to plastic wrap of different widths. It solves the problem that the spacing between the cutting blades used to cut off the excess edges of the plastic wrap before rolling is not easy to adjust during use, thus making it unsuitable for cutting the sides of plastic wrap of different widths.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic wrap winding, pressing, and cutting machine, comprising a fixed frame, wherein two conveying rollers A are rotatably mounted on the side of the fixed frame near the upper surface via roller shaft A, and two conveying rollers B are rotatably mounted on the side of the fixed frame away from the conveying rollers A via roller shaft B. A through-hole is provided on the upper surface of the fixed frame, and a bidirectional lead screw is rotatably mounted on the upper surface of the fixed frame. Threaded sliders are movably sleeved on the outer surface of the bidirectional lead screw near both ends, and the threaded sliders pass through the through-hole. Triangular cutters are fixedly mounted on the lower surfaces of the two threaded sliders, and the triangular cutters are located between the conveying rollers A and B.

[0006] Preferably, an adjusting motor is fixedly installed on the rear surface of the fixing frame, and the end of the output shaft of the adjusting motor is fixedly connected to the end of the bidirectional lead screw.

[0007] Preferably, a take-up roller is rotatably mounted inside the fixed frame near the lower surface, and a take-up motor is fixedly mounted on the rear surface of the fixed frame, with the end of the output shaft of the take-up motor and the end of the take-up roller being fixedly connected.

[0008] Preferably, a transmission motor is fixedly installed on the rear surface of the fixed frame, and pulleys are fixedly connected to the end of the output shaft of the transmission motor and the end of roller A, and the two pulleys are connected by belt drive. Synchronous pulleys are fixedly sleeved on the outer surfaces of roller A and roller B, and the two synchronous pulleys are connected by synchronous belt drive.

[0009] Preferably, gears A are fixedly sleeved on the outer surfaces of both rollers A, and the two gears A mesh with each other.

[0010] Preferably, gears B are fixedly sleeved on the outer surfaces of both rollers B, and the two gears B mesh with each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a fixed frame, conveyor roller A, conveyor roller B, bidirectional lead screw, through-hole, threaded slider, and triangular cutter, achieves the effect of cutting off the excess edges on both sides of the cling film before winding, and is applicable to cling film of different widths. The produced cling film passes between two conveyor rollers B and then between two conveyor rollers A, and is conveyed by conveyor rollers A and B. During the conveying process, the triangular cutter cuts off the uneven waste edges on both sides of the cling film. Because the cutter is triangular, the waste edges can be better separated from the cling film by the action of the triangular inclined surface, so as to avoid the waste edges adhering to the cling film. By rotating the bidirectional lead screw, driving the two threaded sliders to move in opposite directions, the distance between the two triangular cutters can be adjusted to adapt to the cutting of waste edges of cling film of different widths.

[0013] 2. By setting up a take-up roller and a take-up motor, this utility model achieves the effect of preventing the waste edges of the cut plastic wrap from adhering to the plastic wrap. The take-up motor drives the take-up roller to rotate, so that the waste edges of the cut plastic wrap are taken up on the take-up roller to prevent them from adhering to the plastic wrap. At the same time, it is also convenient to centrally process the waste edges.

[0014] 3. By setting a synchronous pulley, this utility model can drive both conveyor roller A and conveyor roller B to rotate simultaneously through a single drive motor. Attached Figure Description

Detailed Implementation

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-Figure 3 As shown, the present invention proposes a cling film winding, edge pressing, and cutting machine, comprising a fixed frame 2. Two conveyor rollers A15 are rotatably mounted on the side of the fixed frame 2 near the upper surface via roller shaft A14. Two conveyor rollers B17 are rotatably mounted on the side of the fixed frame 2 opposite to the conveyor rollers A15 via roller shaft B16. A conveyor motor 5 is fixedly mounted on the rear surface of the fixed frame 2. Pulleys 4 are fixedly connected to the end of the output shaft of the conveyor motor 5 and the end of roller shaft A14, and the two pulleys 4 are connected by a belt drive. Synchronous pulleys 8 are fixedly sleeved on the outer surfaces of roller shaft A14 and roller shaft B16, and the two synchronous pulleys 8 are connected by a synchronous belt drive. The conveyor motor 5 drives roller shaft A14 to rotate via pulleys 4 and belt, while roller shaft A14 and roller shaft B16 are synchronously driven by synchronous pulleys 8 and synchronous belt.

[0023] Gears A6 are fixedly fitted onto the outer surfaces of both rollers A14, and the two gears A6 mesh with each other, causing the two rollers A14 to rotate synchronously. Gears B7 are fixedly fitted onto the outer surfaces of both rollers B16, and the two gears B7 mesh with each other, causing the two rollers B16 to rotate synchronously. A through-hole 11 is provided on the upper surface of the fixed frame 2. A bidirectional lead screw 10 is rotatably mounted on the upper surface of the fixed frame 2. An adjusting motor 9 is fixedly mounted on the rear surface of the fixed frame 2. The end of the output shaft of the adjusting motor 9 is fixedly connected to the end of the bidirectional lead screw 10. The adjusting motor 9 drives the bidirectional lead screw 10 to rotate. Threaded sliders 13 are movably fitted onto the outer surfaces of the bidirectional lead screw 10 near both ends, and the threaded sliders 13 pass through the through-hole 11. The threads on the inner wall of the threaded sliders 13 mesh with the threads on the outer surface of the bidirectional lead screw 10. Triangular cutters 12 are fixedly mounted on the lower surfaces of the two threaded sliders 13, and the triangular cutters 12 are located between the conveyor rollers A15 and B17.

[0024] In this embodiment, the produced plastic wrap passes between two conveyor rollers B17 and then between two conveyor rollers A15. The plastic wrap is conveyed by conveyor rollers A15 and B17. During the conveying process, the triangular cutter 12 cuts off the uneven waste edges on both sides of the plastic wrap. Since the cutter is triangular, the cut waste edges can be better separated from the plastic wrap by the inclined plane of the triangle, so as to avoid the waste edges adhering to the plastic wrap. When the bidirectional lead screw 10 rotates, it drives the two threaded sliders 13 to move in opposite directions, thereby adjusting the distance between the two triangular cutters 12 to adapt to the cutting of waste edges of plastic wrap of different widths.

[0025] Example 2

[0026] like Figure 1 and Figure 3 As shown, the present invention proposes a cling film winding, pressing and cutting machine. Compared with the first embodiment, this embodiment also includes a winding roller 1 rotatably installed inside the fixed frame 2 near the lower surface, and a winding motor 3 fixedly installed on the rear surface of the fixed frame 2. The end of the output shaft of the winding motor 3 is fixedly connected to the end of the winding roller 1.

[0027] In this embodiment, the winding motor 3 drives the winding roller 1 to rotate, so that the waste edges after the cling film is cut are wound onto the winding roller 1 to prevent them from adhering to the cling film, and at the same time, it is convenient to centrally process the waste edges.

[0028] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
