Description

Technical Field

[0001] The invention relates to the technical field of PE heat shrinkable color printing film processing, in particular to a PE heat shrinkable color printing film packaging support device. Background Art

[0002] PE heat shrinkable color printing film is a film with heat shrink properties, usually used for packaging and protecting items. Moreover, PE heat shrinkable color printing film also has color printing function, and various patterns and texts can be printed on the film for identification, publicity or beautification of packaging.

[0003] Since PE heat shrinkable color-printed film is generally wrapped around a cylindrical liner for storage, when packaging the product, the film on the liner is often torn off and transported to the packaging equipment through a support guide roller before the product is packaged. The support guide roller often only provides a support and guide function for the passing heat shrinkable film, but the heat shrink film has strong tensile properties. When it is torn off and transported, its surface will be deformed and no longer flat, which also leads to insufficient aesthetic effect of the packaged product. In view of this, the present application proposes a PE heat shrinkable color-printed film packaging support device. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a PE heat shrinkable color printing film packaging support device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A PE heat shrinkable color-printed film packaging support device comprises a base, wherein the upper end of the base is fixedly connected to a first bracket, a material storage roller is rotatably connected to the side wall of the first bracket, the upper end of the base is also fixedly connected to a second bracket, two hollow rollers are rotatably connected to the side wall of the second bracket, the hollow rollers consist of a soft rubber outer jacket and a hard inner lining, wherein a rotating shaft is fixedly connected to the side wall of the inner lining, the rotating shaft is rotatably connected to the side wall of the second bracket, a plurality of hollow grooves are provided on the circumferential side wall of the rubber outer jacket, two rolling balls are slidably connected in each of the hollow grooves, a telescopic airbag is fixedly connected to the side wall of each rolling ball, a three-way pipe is connected between the two telescopic airbags, an air guide device is connected to the three-way pipe, and the air guide device is used to inhale or exhaust air into the three-way pipe.

[0007] Preferably, the gas guide device includes an gas guide cylinder, in which an air plug is sealingly and slidingly connected, a sliding rod is fixedly connected to the side wall of the gas plug, an end of the sliding rod away from the gas plug is rotatably connected to a rotating rod, an end of the rotating rod away from the sliding rod is rotatably connected to a rocker rod, the rocker rod is fixedly connected to an adjacent rotating shaft, and the gas guide cylinder is provided with an gas guide pipe connected to the interior thereof, and the gas guide pipe is connected to the three-way pipe via a connecting mechanism.

[0008] Preferably, the connecting mechanism includes an air supply pipe, a branch pipe, an air injection pipe and a rotary joint, one end of the air injection pipe is connected to the three-way pipe, the other end of the air injection pipe is connected to the air supply pipe, one end of the branch pipe is connected to the air supply pipe through a rotary joint, and the other end of the branch pipe is connected to the air guide pipe.

[0009] Preferably, a cooling pipe connected to the interior of the air guide cylinder is fixedly connected to the side wall thereof, a heat conduction box is provided on the outside of the cooling pipe, a liquid storage tank is fixedly connected to the upper end of the base, one end of the cooling pipe away from the air guide cylinder is connected to the liquid storage tank, and the liquid storage tank and the air guide cylinder are connected through a liquid suction tube.

[0010] Preferably, one-way valves are installed in the liquid suction pipe and the cooling pipe, and the liquid suction pipe and the cooling pipe are both made of hard steel pipes.

[0011] Preferably, an arc-shaped bracket is fixedly connected to the side wall of the first bracket, a plurality of grooves are opened on the side wall of the arc-shaped bracket, a support rod is slidably connected in the groove, a pressure roller is rotatably connected to the side wall of the support rod, and the support rod is connected to the inner wall of the groove through a spring.

[0012] The present invention has the following beneficial effects:

[0013] 1. By setting a hollow roller composed of a soft rubber outer jacket and a hard inner lining, when the heat shrink film passes through the two hollow rollers, it can not only transport the heat shrink film forward, but also the air guide tube continuously draws and injects air into each three-way pipe. Whenever the hollow roller surfaces on the upper and lower sides contact the heat shrink film, air is injected into the three-way pipe at that location, which can force the telescopic airbag at that location to stretch, thereby pushing the rolling balls on both sides to move to both sides of the hollow roller. For example, the soft rubber outer jacket can act on the heat shrink film to stretch and flatten the heat shrink film to both sides, so that the heat shrink film transported to the packaging equipment is in a straight and flat state, thereby ensuring a more beautiful product packaging effect;

[0014] 2. By setting up components such as a heat conduction box, a cooling tube, a liquid storage tank, and an air guide tube, the heat shrinkable film will slightly heat up after being in contact, rubbed, and stretched with the hollow roller, and the heat shrinkable film is more likely to deform after heating up. By circulating the coolant in the cooling tube, the heat shrinkable film after passing through the two hollow rollers can be cooled down, so that the heat shrinkable film is at a lower temperature before packaging the product, and is less likely to be deformed secondary, further ensuring the subsequent packaging effect.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-6 A PE heat shrinkable color printing film packaging support device includes a base 1, a first bracket 2 having an arc-shaped bracket 5 fixedly connected to the side wall thereof, a plurality of grooves 29 being provided on the side wall of the arc-shaped bracket 5, a support rod 22 being slidably connected in the groove 29, a pressure roller 17 being rotatably connected to the side wall of the support rod 22, and the support rod 22 being connected to the inner wall of the groove 29 via a spring 30. It should be noted that, through the spring 30, the support rod 22 and the pressure roller 17, an outward force can be applied to the support rod 22 by the elastic force of the spring 30, so that the pressure roller 17 is always pressed on the outer wall of the heat shrinkable film roll 4, and as the heat shrinkable film roll 4 continuously transports the heat shrinkable film outward and becomes smaller, the pressure roller 17 can also press the heat shrinkable film roll 4 to ensure its stable outward transport.

[0024] A first bracket 2 is fixedly connected to the upper end of the base 1, and a material storage roller 3 is rotatably connected to the side wall of the first bracket 2. A second bracket 6 is also fixedly connected to the upper end of the base 1, and two hollow rollers are rotatably connected to the side wall of the second bracket 6. The hollow rollers are composed of a soft rubber jacket 7 and a hard lining 16, wherein a rotating shaft 27 is fixedly connected to the side wall of the lining 16, and the rotating shaft 27 is rotatably connected to the side wall of the second bracket 6. A plurality of hollow grooves 31 are provided on the circumferential side wall of the rubber jacket 7, and two rolling balls 26 are slidably connected in each hollow groove 31. A telescopic airbag 25 is fixedly connected to the side wall of each rolling ball 26, and a three-way pipe 24 is connected between the two telescopic airbags 25. The three-way pipe 24 is connected to an air guide device, and the air guide device is used to inhale or exhaust air into the three-way pipe 24.

[0025] The gas guide device includes a gas guide cylinder 10, in which a gas plug 12 is sealed and slidably connected, a slide bar 13 is fixedly connected to the side wall of the gas plug 12, the end of the slide bar 13 away from the gas plug 12 is rotatably connected to a rotating rod 14, the end of the rotating rod 14 away from the slide bar 13 is rotatably connected to a swing rod 15, the swing rod 15 is fixedly connected to an adjacent rotating shaft 27, and a gas guide pipe 11 connected to the inside of the gas guide cylinder 10 is provided, and the gas guide pipe 11 is connected to the three-way pipe 24 through a connecting mechanism. It should be noted that the slide bar 13, the rotating rod 14 and the swing rod 15 form a crank connecting rod structure with the gas plug 12, and when the swing rod 15 rotates, the gas plug 12 can be pulled by the rotating rod 14 and the slide bar 13 to move back and forth in a horizontal square.

[0026] The connecting mechanism includes an air supply pipe 19, a branch pipe 28, an air injection pipe 18 and a rotary joint 20. One end of the air injection pipe 18 is connected to the tee pipe 24, and the other end of the air injection pipe 18 is connected to the air supply pipe 19. One end of the branch pipe 28 is connected to the air supply pipe 19 through the rotary joint 20, and the other end of the branch pipe 28 is connected to the air guide pipe.

[0027] A cooling pipe 23 communicating with the inside of the gas cylinder 10 is fixedly connected to the side wall thereof, a heat conduction box 9 is arranged outside the cooling pipe 23, a liquid storage tank 8 is fixedly connected to the upper end of the base 1, and the end of the cooling pipe 23 away from the gas cylinder 10 is communicated with the liquid storage tank 8, and the liquid storage tank 8 and the gas cylinder 10 are communicated with each other through a liquid suction pipe 21. A one-way valve is installed in the liquid suction pipe 21 and the cooling pipe 23, and both the liquid suction pipe 21 and the cooling pipe 23 are made of hard steel pipes. It should be noted that the liquid suction pipe 21 and the cooling pipe 23 made of hard steel pipes can support the gas cylinder 10 and the heat conduction box 9, so that the positions of the gas cylinder 10 and the heat conduction box 9 remain unchanged.

[0028] Furthermore, a liquid filling port is provided on the liquid storage tank 8, through which cooling water can be added to the liquid storage tank 8. The one-way valve in the suction pipe 21 limits the cooling water in the liquid storage tank 8 to flow from the liquid storage tank 8 to the air cylinder 10 in one direction, while the one-way valve in the cooling pipe 23 limits the cooling water to flow from the air cylinder 10 to the liquid storage tank 8 in one direction.

[0029] In the present invention, the heat shrink film roll 4 can be placed on the stock roller 3, and the heat shrink film of the heat shrink film roll 4 can be passed between two hollow rollers and transported to the packaging equipment, and the packaging equipment can be used to package the product. When the heat shrink film passes through the two hollow rollers, the friction force can drive the two hollow rollers to rotate, that is, the rubber jacket 7 and the inner lining 16 inside it both rotate, wherein the upper inner lining 16 can drive the swing rod 15 to rotate synchronously through the rotating shaft 27, and the swing rod 15 can pull the slide bar 13 to move horizontally back and forth through the rotating rod 14, and the slide bar 13 can pull the air plug 12 to move back and forth synchronously, when the air plug 12 moves to the right, the ball 26 on the side of the rubber jacket 7 will contact the heat shrink film, and at this time, the rightward movement of the air plug 12 can squeeze out the air on the left side of the air plug 12, and pass through the air guide pipe 11, the branch pipe 28 in turn. , the rotary joint 20, the air delivery pipe 19, and the air injection pipe 18 are input into the three-way pipe 24, and finally input into the telescopic airbag 25 through the three-way pipe 24, and force the telescopic airbag 25 to stretch, then the stretched telescopic airbag 25 will push the ball 26 to move toward the end of the rubber jacket 7, then when the two balls 26 move toward the two ends of the rubber jacket 7, at this time, the ball 26 can act on the rubber jacket 7 through the inner wall of the hollow groove 31, and finally act on the surface of the heat shrink film through the rubber jacket 7, so that the heat shrink film passing through the two hollow rollers can be stretched to both sides, so that the heat shrink film can be straight and flat, ensuring the aesthetic effect of subsequent packaging.

[0030] When the air plug 12 moves to the right, the ball 26 on the side of the rubber jacket 7 will leave the heat shrink film. At this time, the air plug 12 moves to the right and the air in the telescopic airbag 25 can be sucked back along the tee pipe 24, the air injection pipe 18, the air delivery pipe 19, the rotary joint 20, the branch pipe 28, and the air guide pipe 11, so that the telescopic airbag 25 can be contracted. The contraction of the telescopic airbag 25 can pull the ball 26 back to reset, which is convenient for the next straightening process of the heat shrink film.

[0031] Further, such as Figure 1 As shown, the straightened and stretched heat shrink film will pass through the heat conduction box 9. The heat shrink film will slightly heat up after contact, friction and stretching with the hollow roller, and the heat shrink film is more easily deformed after heating. When the air plug 12 moves to the left, the space on its right side increases, which can generate negative pressure to suck the cooling water in the liquid storage tank 8 into the air guide tube 10 along the suction pipe 21. When the air plug 12 moves to the right, the cooling water on the right side of the air plug 12 can be squeezed into the cooling pipe 23, and finally flow back to the liquid storage tank 8 through the cooling pipe 23. As the air plug 12 moves back and forth left and right, the cooling water can continue to circulate in the cooling pipe 23. When the cooling water flows in the cooling pipe 23, the heat of the heat shrink film on the heat conduction box 9 can be quickly carried and dissipated, so that the heat shrink film maintains a low temperature state before the product is packaged, making the heat shrink film less likely to undergo secondary deformation, further ensuring the subsequent packaging effect.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
