Description

Technical Field

[0002] The wrapping machine market is gaining more and more attention in actual production. In the existing market wrapping technology, the chassis of the wrapping machine rotates to drive the goods to rotate, and the goods are packed into a whole by using the retractability and self-adhesiveness of the wrapping film, so that the goods will not collapse during transportation. It also has the effects of dustproof and moisture-proof. However, after the wrapping film is cut, it is easy to be adsorbed on the film frame by static electricity. If the workers do not handle it in time, it is easy to be entangled with other wrapping rollers, affecting the wrapping efficiency. In addition, setting up multiple drive motors consumes a lot of energy and occupies a large space.

[0003] CN202222754025.3 discloses an automatic film cutting seat, which is configured to automatically cut the film by putting the wrapping film roll on the film roll positioning rod and then passing the wrapping film through the main frame, so that the wrapping film is fitted with the first stretching roller and the second stretching roller, and the motor drives the first stretching roller and the second stretching roller to rotate in opposite directions through the transmission component to transport the wrapping film outward. At the same time, the wrapping film contacts the upper electrostatic cloth during the film discharge process, and static electricity is applied to the wrapping film to improve the fit between the wrapping film and the goods. Then the wrapping film is stretched outward at the position of the film discharge roller, and at the same time, the film discharge fan blows the wrapping film to the surface of the goods, and cooperates with the rotation of the winding machine to pull the wrapping film. At the same time, an automatic film cutting mechanism is provided, which can automatically cut the film after the goods are wrapped. However, the film seat has the following problems: first, the stability of the film roll is poor, which makes the efficiency of film roll output low. Secondly, the film cutting method is complicated, the structure is complex, and the film discharge smoothness is not good. Utility Model Content

Before passing through the clamping roller 55 and the film discharge roller 54, the film passes through the guide wheel 51, and an electrostatic rod is provided at the left front end of the guide wheel 51. Therefore, when the film enters the clamping roller 55 and the film discharge roller 54, there is static electricity on the film. The static electricity removal component 6 is used to prevent the film from being entangled with the film discharge mechanism 5, and then the film is smoothly and parallelly discharged and then adsorbed to the object that needs to be wrapped by surface static electricity, thereby achieving efficient film wrapping.

[0035] Further, the static electricity removal component 6 includes a group of oblique plates 61 inclined to the left and close to each other, and the oblique plates 61 are evenly connected to the side away from each other with three groups of fans 62, and the outside of the fans 62 is wrapped with a guide protection shell 63, and the rear side of the guide protection shell 63 is fixedly connected to the oblique plate 61, and a guide plate 64 is provided on the left side of the guide protection shell 63, and the guide plate 64 is a Z-shaped metal block whose left end is close to the film discharge mechanism 5. The fans 62 start to rotate after being energized by the external circuit, and the side away from each other is provided with There are ventilation holes, which are arranged on the guide protection shell 63 to facilitate ventilation by the fan 62 and change of wind direction by the guide plate 64, so that the wind flow acts on the front and rear ends of the diaphragm, reducing static electricity when the diaphragm is out of the film, preventing the diaphragm from being adsorbed on the film-out roller 54 and the clamping roller 55, and reducing the occurrence of sticking and disorder when the film is out. Fans 62 are arranged at the front and rear ends of the diaphragm, and the fan 62 and the guide plate 64 are used to blow air to the front and rear ends of the diaphragm, so as to keep the diaphragm in a parallel state when the film is out, which is convenient for subsequent film wrapping.

[0036] Furthermore, the film cutting and punching assembly 7 includes a hollow frame 71, the lower end of the hollow frame 71 is fixedly connected to the lower surface of the inside of the film frame 1, and the lower side of the center position of the hollow frame 71 is connected to the electromagnetic coil block 72, the upper end of the electromagnetic coil block 72 is fixedly connected to the C-type clamping block 73, the upper center position of the C-type clamping block 73 is provided with a movable shaft, the center position of the movable shaft is movably connected to the punching block 74, and a row of punching needles 75 are provided on the left surface of the punching block 74, and an electromagnetic coil is provided on the electromagnetic coil block 72. When the electromagnetic coil is energized, the punching block 74 swings back and forth on the movable shaft, and the punching needle 75 is provided on the punching block 74. The punching needle 75 contacts the diaphragm during the swinging process, so that a row of broken holes are pierced on the diaphragm. When the stationary machine 31 and the small motor 21 are not working, the film roll will not produce a film, and the excess film is pulled and broken, thereby achieving the effect of film cutting. The structure is compact, the film cutting effect is good, and the space occupied is small. The overall structure has a high degree of integration.

[0037] Working process: first, place the film roll 24 on the limit block 23 and clamp it. The outer side of the limit block 23 is wrapped with a rubber layer, which is elastic and convenient for adapting to the regular film roll 24. Then, the width of the small motor 21 is smaller than the diameter of the limit block 23, and the film roll 24 will not contact the outer side of the small motor 21. In this way, the small motor 21 works, drives the rotating shaft 22 to rotate, thereby driving the limit block 23 to rotate, controlling the rotation speed of the film roll 24, and thus controlling the film output speed;

[0038] Secondly, the film roll passes through the auxiliary roller 13 on the right side and enters the roller group 4, passes through the No. 1 roller 41, the No. 2 roller 42 and the No. 3 roller 43 respectively, and reaches the auxiliary roller 13 on the left side through the transition roller 14, enters the film discharging mechanism 5, passes through between the film discharging roller 54 and the clamping roller 55 in the film discharging mechanism 5, and thus reaches the cargo position for film wrapping. When passing through between the film discharging roller 54 and the clamping roller 55, the static electricity removal component 6 starts to work, and the fan 62 rotates to make the wind flow blow to the position of the guide plate 64. The guide plate 64 brings the wind to the front and rear ends of the film, thereby achieving the effect of static electricity removal, preventing the film from being electrostatically adsorbed on other structures, causing unnecessary film wrapping knotting problems;

[0039] It is worth noting that when the film is cut, it is only necessary to energize the electromagnetic coil block 72, and the electromagnetic coil is energized to make the punching block 74 on it magnetic. It is only necessary to set a magnetic block on the other side of the diaphragm. The punching block 74 will be attracted after being energized because of its magnetism, so that the punching needle 75 can contact and puncture the diaphragm to achieve the function of punching. Then the punching block 74 loses power and is no longer magnetic. A reset spring is provided inside the punching block 74 and the movable shaft to reset the punching block 74. The principle is simple and the punching method is simple.

[0040] The whole device has a simple driving mode, and the film output speed is controllable, which avoids the waste of film output from the film roll 24 due to inertia. In addition, a static electricity removal component 6 and a film cutting and punching component 7 are provided to make the film output smoother, the film wrapping efficiency is higher, the film cutting structure is compact, and the film cutting method is simple and efficient.
