Description

Technical Field

[0001] The invention relates to a cutting device, in particular to a cutting device for a degradable and antibacterial fruit and vegetable packaging film. Background Art

[0002] Degradable antibacterial fruit and vegetable packaging film is an environmentally friendly packaging material specially designed for preserving fruits and vegetables. It can not only effectively inhibit the growth of bacteria and molds and extend the shelf life of fruits and vegetables, but also can naturally degrade after the end of its service life to reduce environmental pollution. When it is used for packaging, it needs to be cut into different lengths to adapt to different packaging. In the prior art, the processing method used is either to wait for the cutting time manually and directly pull and cut near the cutter for direct packaging, or to collect the piled packaging film after cutting for unified manual packaging. In the first method, the processing efficiency is low, and the personnel are directly exposed to the cutter, which has a greater safety risk. In the second method, although it can be uniformly collected and packaged after cutting, the packaging film is thin, so it is necessary to pick and distinguish manually during packaging, which is time-consuming and labor-intensive. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a degradable and antibacterial fruit and vegetable packaging film cutting device, which can directly distinguish and collect the cut packaging film, and transport it to the manual packaging area after collection, so that personnel can directly pick up the packaging in the manual packaging area, which is more convenient.

[0004] The present invention provides the following technical solutions:

[0005] A degradable antibacterial fruit and vegetable packaging film cutting device, comprising a redirecting roller for redirecting the unrolled packaging film to vertically drop, a hanger for installing a pulling part, a cutting part and a pressing part below the redirecting roller, and a conveyor below the hanger, wherein a plurality of groups of T-shaped brackets are installed on the conveying direction at the same interval, and two groups of symmetrical plate clamps are installed on each group of T-shaped brackets, and when two adjacent groups of T-shaped brackets move below the cutting part, the pressing part is used to press the adjacent plate clamps of the two groups of T-shaped brackets toward the middle to form a gap for the pulling part to pass through, the pulling part is used to pull and unroll the hanging packaging film in a vertical direction, and the cutting part is used to cut and break the packaging film pulled to a required length, and at the same time, the pressing part relaxes and presses the two adjacent groups of plate clamps, and then the broken packaging film is clamped by the two adjacent groups of plate clamps, and is driven by the conveyor to be transported to a manual packaging area to be picked up manually;

[0006] At this point, each group of separated packaging films can be clamped by two groups of plate clamps and transported to the manual packaging area. Each packaging film can be directly distinguished when separated, which saves time and effort. The distinguished and collected packaging films are transported to the manual packaging area by the conveyor, so that personnel can directly pick up the packaging in the manual packaging area, which is more convenient.

[0007] Preferably, the pulling part includes two groups of clamping plates, each of which is driven by two groups of screw rods 1 for vertical lifting and lowering. The two groups of clamping plates are arranged opposite to each other, and the mounting block for connecting and installing screw rod 1 is also screwed on the outside of screw rod 2. Screw rod 2 is provided with four groups distributed in a rectangular shape, and when the four groups of screw rods 2 rotate synchronously, they are used to drive the two groups of clamping plates to move in opposite directions through the mounting block; at this point, when the two groups of clamping plates move toward each other to clamp and position the packaging film and move vertically downward, the packaging film can be pulled downward stably, and after being pulled to a certain height, the two groups of clamping plates move away from each other to relax the clamping of the packaging film, and under the drive of screw rod 1, they can return to their original positions again to wait for the next clamping and pulling, and the overall movement stability is good.

[0008] Preferably, the cutting part includes two groups of mounting plates driven by screw rod three for reverse movement, screw rod three is parallel to screw rod two and staggered, and through holes for screw rod two to pass through are provided on the two groups of mounting plates, and a group of cutting plates and a group of cutting knives driven by a top cylinder are respectively installed at the bottom ends thereof, screw rod three is used to drive the cutting knives and the cutting plates to move toward each other, and the top cylinder is used to move toward the cutting plate after the cutting plate moves to the side that is in contact with the packaging film to cooperate with the cutting knife to separate and cut the packaging film.

[0009] Preferably, the top and bottom ends of the plate clamp are respectively provided with a group of pressing cams, and the back side thereof is also provided with a group of adapter sleeves which are installed at one end of the T-shaped bracket, and it is connected to the T-shaped bracket through a top pressure spring, and the top pressure spring is used to press the plate clamp to make it rotate around the adapter end with the T-shaped bracket, and make the bottom ends of the plate clamps on two adjacent groups of T-shaped brackets abut to clamp the packaging film.

[0010] Preferably, the pressing convex shaft is an elastic rubber convex shaft, so that when the pressing convex shaft abuts against the pressing portion or against each other to clamp the packaging film, the stability and service life are better.

[0011] Preferably, the pressing part includes two groups of vertical plates driven by screw rod four to perform reverse movement, each of the two groups of vertical plates is connected to a group of push blocks through a push cylinder, the push blocks are slidably mounted on the vertical plates along the vertical direction, the screw rod four is also parallel to the screw rod two and staggered, the two groups of vertical plates are also provided with through holes for screw rods two and three to pass through, the two groups of push blocks are used to push the pressing cams on the top ends of the two adjacent groups of plate clamps, so that they rotate around the connecting end of the plate clamp and the T-shaped bracket to form a gap for the pulling part to pass vertically.

[0012] At this point, when a group of packaging films needs to be cut, it is only necessary to start the conveyor so that two groups of adjacent T-shaped brackets move to the bottom of the cutting part, and the pressing part presses the plate clips on the two groups of T-shaped brackets to form a gap for the pulling part to pass through.

[0013] Preferably, the two groups of vertical plates are initially distributed in an upward flared shape under the pressure of the pressing spring. When the pressing part presses the vertical plates to a vertical distribution, a gap is formed for the pulling part to pass vertically. At this point, the maximum passing gap can be formed to facilitate the pulling part to pass smoothly.

[0014] Preferably, a driving roller for cooperating with the redirecting roller to clamp the packaging film is also provided on one side of the redirecting roller. The driving roller rotates under the drive of the driving motor to provide a downward driving unwinding force for the packaging film, thereby cooperating with the pulling part to unwind the packaging film with better stability.

[0015] Preferably, a group of base blocks are respectively installed on the four groups of mounting blocks located at the bottom, and a group of pulling blocks are pushed by a group of pulling cylinders on the two groups of base blocks driven by the same group of screw rods 2. The two groups of pulling blocks located on the same group of screw rods 2 move toward each other to clamp and position the packaging film pulled to the bottom, so that the subsequent pulling part can stably detach from the packaging film and return to the initial position after pulling.

[0016] The beneficial effects of the present invention are as follows: the degradable antibacterial fruit and vegetable packaging film cutting device provided by the present invention can make each group of cut packaging films clamped by the corresponding two groups of plate clamps and transported to the manual packaging area, and each packaging film can be directly distinguished when cut, which is more time-saving and labor-saving, and the distinguished and collected packaging films are transported to the manual packaging area by the conveyor, so that personnel can directly pick up the packaging in the manual packaging area, which is more convenient;

[0017] During the specific operation, the head end of the packaging film is first redirected by the redirecting roller and then clamped and positioned by the two sets of clamps at the initial position. When the clamps are clamped and positioned, it is only necessary to control the synchronous rotation of the screw rod 2 through the motor, which is more convenient, and then the conveyor is started to make the two sets of T-shaped brackets move to the cutting work area. At this time, the two adjacent sets of plate clamps on the two sets of T-shaped brackets in the working area can be pressed by the two sets of vertical plates of the pressing part to form a gap for the pulling part to pass through, and then the two sets of clamps of the pulling part clamp and position the packaging film to move vertically downward, and after being pulled to a certain height, The two sets of clamps move away from each other to loosen the clamping of the packaging film, and under the drive of screw rod 1, they can return to the initial position again to wait for the next clamping and pulling, and then the cutting part cuts the packaging film, and the pressing part also relaxes the pressing on the plate clamp. Driven by the pressing spring, the plate clamp can be distributed in an upward flared shape again, and the pressing cam at the bottom end clamps and positions the packaging film, and then moves to the next station with the conveyor. During the cutting work, the conveyor conveys the distance of a T-shaped bracket each time it is started. At this point, batch continuous production can be achieved.
