Description

Technical Field

[0001] The utility model relates to the field of fixed-length shearing mechanisms, in particular to a fixed-length shearing mechanism for plastic packaging films. Background Art

[0002] Plastic film is usually used as packaging film. Before packaging, the plastic film usually needs to be cut into a certain size. Currently, the equipment for cutting plastic film usually includes a pinch roller, a cutting mechanism and a positioning clamping mechanism.

[0003] According to the published patent 202022775844.7, the fixed-length cutting mechanism for plastic packaging film includes a workbench, a support rod is connected to the upper outer side of the workbench, a suction cup is connected to the front surface of the workbench, a first supporting leg is connected to the upper part of the suction cup, a second supporting leg is connected to the inside of the first supporting leg, a bolt is connected to the outer side of the first supporting leg, and the first supporting leg and the second supporting leg are detachably connected by the bolt. The fixed-length shearing mechanism for plastic packaging film, by providing a mounting seat, a connecting rod and a storage platform, a first support leg, a second support leg, a bolt and a suction cup, makes the utility model have the function of facilitating collection and adjusting the height, and is convenient for uniformly collecting the sheared packaging film, while avoiding the height difference between the guide strip and the packaging film to affect the efficiency of shearing and conveying the packaging film, thereby improving the efficiency of the shearing mechanism. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the utility model has the function of facilitating collection by providing a mounting seat, a connecting rod and a storage platform, and effectively improving the usability of the fixed-length shearing mechanism, when connected, the storage platform and the connecting rod are installed together in the mounting seat and fixed by tightening bolts. During use, the connecting rod is rotated to The connecting rod is in a horizontal position and the fastening bolts are tightened, so that the storage table and the workbench can be in a flush position, so that the packaging film can be cut and dropped on the storage table. This solves the problem that the existing fixed-length cutting mechanism of the packaging film is not easy to collect and process the cut packaging film uniformly when it is working, and a certain amount of manpower is required to collect the packaging film after cutting, thereby reducing the convenience of using the cutting mechanism. However, during use, the traditional fixed-length cutting mechanism of the plastic packaging film, when the length of the plastic packaging film is longer than the length of the cutting knife, will result in the need to continuously cut the plastic packaging film at different positions, which will increase the number of cuttings and affect the cutting efficiency. Moreover, the plastic packaging film after cutting is only placed on the storage table, and the staff is required to take and collect the plastic packaging film, which is not very convenient. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a fixed-length cutting mechanism for plastic packaging film to solve the problem that the current traditional fixed-length cutting mechanism for plastic packaging film needs to continuously cut the plastic packaging film at different positions when the length of the plastic packaging film is longer than the length of the cutting knife, which increases the number of cutting times and affects the cutting efficiency. Moreover, the plastic packaging film after cutting is only placed on a storage table, and staff are required to take and collect the plastic packaging film, which is not very convenient.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a fixed-length shearing mechanism for plastic packaging film, including a device top plate, and also including:

[0006] Electric telescopic cylinder, installed on top of the device top plate;

[0007] The fixed-length shearing mechanism is fixed at the bottom of the electric telescopic cylinder. The fixed-length shearing mechanism comprises a concave frame plate. A rotating cylinder is arranged inside the concave frame plate. A plurality of cutting knives are fixed on the outer wall of the rotating cylinder. The lengths of the plurality of cutting knives are different.

[0008] Preferably, a rotating rod passes through the inside of the rotating cylinder, and the rotating rod is fixedly connected to the penetration position of the rotating cylinder, a first motor shaft is fixed to one side of the rotating cylinder, an end of the first motor shaft away from the rotating rod passes through a concave frame plate and is connected to a first motor, and a concave frame plate is installed on one side of the first motor.

[0009] Preferably, one end of the rotating rod away from the first motor shaft is rotatably connected to a first bearing, and one end of the first bearing away from the rotating rod is installed with a concave frame plate.

[0010] Preferably, support rods are fixed to the four corners of the bottom of the top plate of the device, and a first fixing plate and a second fixing plate are fixed to the bottom of the support rods respectively. A first groove and a second groove are respectively formed on one side of the first fixing plate and the second fixing plate.

[0011] Preferably, a second motor is installed inside the first groove, a second motor shaft is connected to one side of the second motor, a rotating plate is fixed to the end of the second motor shaft away from the second motor, a second bearing is installed inside the second groove, a connecting rod is rotatably connected to one side of the second bearing, and a rotating plate is fixed to the end of the connecting rod away from the second bearing.

[0012] Preferably, a supporting base frame is fixed to the bottom of the first fixing plate and the second fixing plate, and a material receiving shell is detachably connected between the two supporting base frames.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model combines a rotating drum, a cutting knife and an electric telescopic cylinder, and can utilize the electric telescopic cylinder to drive the rotating drum and the cutting knife to move downward, and utilize the cutting knife to cut the plastic packaging film. Moreover, when it is necessary to cut plastic packaging films of different lengths, the motor can be turned on, and the rotating drum is driven by the motor to rotate. A plurality of cutting knives of different lengths are arranged on the surface of the rotating drum, and the cutting knife that meets the length of the plastic packaging film can be selected to be moved to the bottom for cutting. This solves the technical problem that the fixed-length cutting mechanism of the traditional plastic packaging film needs to cut the plastic packaging film at different positions continuously when the length of the plastic packaging film is longer than the length of the cutting knife, which increases the number of cutting times and affects the cutting efficiency.

[0015] 2. The utility model combines the second motor, the rotating plate and the connecting rod, so that the plastic packaging film after cutting will fall on the surface of the rotating plate, and the second motor can drive the rotating plate to rotate, so that the plastic packaging film on the surface of the rotating plate falls into the interior of the material receiving shell.

The electric telescopic cylinder 2 can be opened to drive the rotating cylinder 204 and the cutting knives 207 to move downward, and the cutting knives 207 are used to shear the plastic packaging film, and when it is necessary to shear the plastic packaging films of different lengths, the first motor 202 can be opened, The first motor 202 drives the first motor shaft 203, which drives the rotating rod 205 through the first motor shaft 203, and the rotating rod 205 drives the rotating cylinder 204 to rotate. A plurality of cutting knives 207 of different lengths are arranged on the surface of the rotating cylinder 204. The cutting knife 207 that matches the length of the plastic packaging film can be selected to move to the bottom for cutting, thereby solving the technical problem of the fixed-length shearing mechanism of the traditional plastic packaging film. When the length of the plastic packaging film is longer than the length of the cutting knife 207, it will result in the need to continuously shear different positions of the plastic packaging film, which will increase the number of shearing times and affect the cutting efficiency.

[0022] For details, see Figure 3 A rotating rod 205 passes through the inside of the rotating cylinder 204, and the rotating rod 205 is fixedly connected to the penetration position of the rotating cylinder 204. A first motor shaft 203 is fixed to one side of the rotating cylinder 204. One end of the first motor shaft 203 away from the rotating rod 205 passes through the concave frame plate 201 and is connected to the first motor 202.

Moreover, when it is necessary to cut plastic packaging films of different lengths, the first motor can be turned on, the first motor drives the first motor shaft, and the motor shaft drives the rotating rod 205, and the rotating rod 205 drives the rotating cylinder 204 to rotate. A plurality of cutting knives 207 of different lengths are arranged on the surface of the rotating cylinder 204, and the cutting knife 207 that matches the length of the plastic packaging film can be selected. Move to the bottom and then cut. After cutting, the plastic packaging film will fall on the surface of the rotating plate 302. When the plastic packaging film needs to be actively collected, the second motor 306 can be turned on. The second motor 306 drives the second motor shaft 307. The second motor shaft 307 can drive the rotating plate 302 to rotate, so that the plastic packaging film on the surface of the rotating plate 302 falls into the inside of the material receiving shell 303. After the staff removes the material receiving shell 303, they can directly drag the material receiving shell 303 away, eliminating the need for the staff to manually collect the plastic packaging film.
