Description

Technical Field

[0001] The present invention relates to the technical field of heat shrink film production equipment, and particularly to an automatic conveying and winding equipment for heat shrink film. Background Art

[0002] A heat shrink film is a plastic film that can shrink and tightly wrap an object under heating conditions, and is widely used in the packaging fields of multiple industries such as food, medicine, electronics, and daily necessities. During production, the raw material forms a tubular heat shrink film after passing through a blown film machine, passes through a cooling cylinder, and cooling water is sprayed inside the cooling cylinder to cool the heat shrink film. After the heat shrink film is cooled and shaped, it enters a water tank for secondary cooling. After the heat shrink film enters the water tank, it changes from a tubular shape to a flat shape, and after being output from the water tank, it is dried and wound into a heat shrink film roll.

[0003] During the process of conveying the heat shrink film, the heat shrink film is cooled. When the heat shrink film passes through the cooling cylinder, since the heat shrink film is in a tubular structure at this time and its interior is filled with air, the surface of the heat shrink film is in contact with the inner surface of the cooling cylinder. During the process of the heat shrink film passing through the cooling cylinder, the gap between the heat shrink film and the cooling cylinder is too small, which affects the spraying of the cooling water, resulting in insufficient contact between the cooling water and the heat shrink film, and affecting the cooling and shaping effect of the heat shrink film; the used cooling water directly enters the lower water tank, causing the cooling water in the water tank to be mixed with the used cooling water. The temperature of the used cooling water rises, and after being mixed with the cooling water in the water tank, it will affect the cooling effect of the cooling water in the water tank on the heat shrink film.

Detailed embodiments

[0029] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] As Figure 1 shown, an automatic conveying and winding device for a heat shrinkable film includes a base 1. In the middle position of the upper surface of the base 1, there is a water tank 2 for secondary water cooling of the heat shrinkable film. On the front surface of the water tank 2, there is a drying part 3 for drying the heat shrinkable film. On the upper surface of the base 1 and on the front side of the drying part 3, there is a winding part 4. On the upper surface of the base 1, there is a collecting mechanism 5 for collecting circulating cooling water, and on the collecting mechanism 5, there is a cooling mechanism 6 for water-cooling and shaping the heat shrinkable film.

[0031] As Figure 1 and Figure 2 shown, the cooling mechanism 6 includes a support seat 61 fixedly connected to the collecting mechanism 5. At the center position of the upper surface of the support seat 61, there is a first cooling member 62. On the first cooling member 62, there is a second cooling member 63 for evenly spraying cooling water on the surface of the heat shrinkable film. At the top of the first cooling member 62, there is a reset member 64. On the upper surface of the support seat 61 and outside the first cooling member 62, there is a driving member 65.

[0032] As Figure 2 、 Figure 3 and Figure 4 shown, the first cooling member 62 includes a plurality of fixing rings 621 evenly distributed in the vertical direction. Through holes are provided on the upper surface of the support seat 61 corresponding to the positions of the fixing rings 621. A plurality of evenly distributed brackets 622 are fixedly connected to the outer circumferential surfaces of adjacent two fixing rings 621. The second cooling member 63 includes a plurality of spraying rings 631 evenly distributed in the vertical direction. The spraying rings 631 are rotatably connected between adjacent two fixing rings 621. Overflow grooves 623 are provided on the inner circumferential surfaces of the fixing rings 621 between adjacent two spraying rings 631. A first water supply pipe 624 is fixedly connected and penetrates through the outer circumferential surfaces of the plurality of fixing rings 621.

[0033] As Figure 2 、 Figure 3 and Figure 4As shown, among the multiple fixed rings 621 distributed vertically, the widths of the top and bottom fixed rings 621 are smaller than that of the middle fixed ring 621. A water supply pipe 624 is fixedly connected and penetrates through the outer circumferential surfaces of the multiple fixed rings 621 where the overflow grooves 623 are opened. An auxiliary roller is provided on the surface of the support 622 close to the spray ring 631, which changes the sliding friction between the support 622 and the spray ring 631 into rolling friction.

[0034] During specific use, the heat shrinkable film is conveyed in a tubular shape to the inside of the fixed ring 621 after blow molding extrusion. The heat shrinkable film passes through the multiple fixed rings 621 and then is conveyed through the through holes on the support seat 61 to the lower part of the support seat 61. When the heat shrinkable film passes through the fixed ring 621, cooling water is continuously conveyed into the overflow groove 623 through the water supply pipe 624 on the fixed ring 621. With the continuous conveyance of the cooling water, the cooling water overflows from the inside of the overflow groove 623. At this time, since the heat shrinkable film adheres to the inner circumferential surface of the fixed ring 621, the overflowed cooling water adheres to the surface of the heat shrinkable film, cooling and lowering the temperature of the heat shrinkable film.

[0035] As Figure 2 、 Figure 3 and Figure 4 As shown, a plurality of uniformly distributed linkage frames 632 are fixedly connected to the outer circumferential surface of the multiple spray rings 631. A water supply pipe 633 is fixedly connected and penetrates through the outer circumferential surfaces of the multiple spray rings 631. A plurality of nozzles are evenly distributed on the inner circumferential surface of the spray ring 631. There is a certain distance between the water spraying end of the nozzle and the inner surface of the fixed ring 621. A section of hose is provided at the middle position of the water supply pipe 633.

[0036] During specific use, when the heat shrinkable film passes through the fixed ring 621, cooling water is conveyed into the spray ring 631 through the water supply pipe 633. The cooling water is sprayed out through the nozzles on the spray ring 631 to cool and lower the temperature of the heat shrinkable film. At the same time, with the gap reserved between the water spraying end of the nozzle and the inner surface of the fixed ring 621, it can make the cooling water sprayed out by the nozzle have sufficient space to contact the heat shrinkable film, so that the amount of cooling water contacting the heat shrinkable film is larger, facilitating better cooling and shaping of the heat shrinkable film. At the same time, the spray ring 631 is driven by the driving member 65 to rotate reciprocally for a short distance on the fixed ring 621, so that the cooling water sprayed out by the nozzles on the spray ring 631 can more fully cover the surface of the heat shrinkable film passing through the nozzles.

[0037] As Figure 2 and Figure 5As shown, the reset member 64 includes two vertically symmetric annular tracks 641 fixedly connected to the first cooling member 62. Connecting chutes are provided on the opposite surfaces of the two annular tracks 641. Sliding blocks 642 are slidably connected to the positions corresponding to the linkage frames 632 inside the connecting chutes. A linkage plate 643 is fixedly connected to the upper surfaces of the sliding blocks 642 and the linkage frames 632. A fixed block 644 is fixedly connected to one side of the sliding block 642 inside the connecting chute. A connecting spring is provided between the sliding block 642 and the fixed block 644.

[0038] As Figure 2 and Figure 6 As shown, the driving member 65 includes a fixed seat 651 fixedly connected to the upper surface of the support base 61. An installation sleeve 652 is fixedly connected to the top of the fixed seat 651. An external gear ring 653 is rotatably connected inside the installation sleeve 652. Elastic connection seats 654 are fixedly connected to the positions corresponding to the linkage frames 632 on the inner circumferential surface of the external gear ring 653. A wedge-shaped push block 655 is fixedly connected to one end of the elastic connection seat 654 facing the center of the installation sleeve 652.

[0039] As Figure 2 and Figure 6 As shown, the external gear ring 653 is embedded inside the installation sleeve 652. The external gear ring 653 and the installation sleeve 652 are coaxial. The wedge-shaped push block 655 is slidably engaged with its corresponding linkage frame 632. A driving motor is fixedly installed on the rear side of the upper surface of the support base 61 through a motor base. A driving gear is fixedly connected to the output shaft of the driving motor. An opening for exposing the teeth of the external gear ring 653 is provided on the installation sleeve 652 corresponding to the driving gear. The driving gear is engaged with the external gear ring 653. When the elastic connection seat 654 is in a normal state, when the wedge-shaped push block 655 passes by the linkage frame 632, the inclined surface of the wedge-shaped push block 655 fits on the linkage frame 632. The elastic force of the elastic connection seat 654 is greater than the sum of the elastic force of the connecting spring between the sliding block 642 and the fixed block 644 and the frictional force between the fixed ring 621 and the spray ring 631.

[0040] During specific use, the driving motor drives the external gear ring 653 to continuously rotate inside the installation sleeve 652 through the driving gear on it. The external gear ring 653 drives the wedge-shaped push block 655 to continuously rotate through the elastic connection seat 654. When the wedge-shaped push block 655 rotates to contact the linkage frame 632, the linkage frame 632 generates resistance to the wedge-shaped push block 655. The wedge-shaped push block 655 pushes the linkage frame 632 to rotate. The linkage frame 632 drives the spray ring 631 to rotate on the fixed ring 621. At the same time, the linkage frame 632 drives the sliding block 642 to slide inside the annular track 641 through the linkage plate 643, and stretches the connecting spring between the sliding block 642 and the fixed block 644.

[0041] When the linkage 632 rotates to the position of the bracket 622, the bracket 622 limits the movement of the linkage 632. As the external gear ring 653 continues to rotate, the inclined surface of the wedge-shaped push block 655 slides on the linkage 632 and compresses the elastic connecting seat 654. When the external gear ring 653 drives the wedge-shaped push block 655 through the elastic connecting seat 654 to cross the contacted linkage 632 at this time, under the action of the self-elastic force of the elastic connecting seat 654, the wedge-shaped push block 655 is restored to its original position. At the same time, under the action of the self-elastic force of the connecting spring, the linkage 632 is driven by the sliding block 642 to return to its original position. As the external gear ring 653 continues to rotate, when the external gear ring 653 drives the wedge-shaped push block 655 past the next linkage 632, the above steps are repeated to continue driving the linkage 632 to rotate a certain distance, thereby realizing the reciprocating rotation of a small distance of the linkage 632 driving the spray ring 631 on the fixed ring 621.

[0042] As Figure 1 and Figure 7 shown, the collection mechanism 5 includes a storage tank 51 fixedly connected to the upper surface of the base 1. The rear surface of the water tank 2 is fixedly and penetratingly connected with a return pipe 52. Above the water tank 2, there is a collection member 53. One end of the return pipe 52 away from the water tank 2 leads into the interior of the storage tank 51. Inside the storage tank 51, there is a water pump (not shown in the figure), and the return pipe 52 leads into the interior of the storage tank 51 and is fixedly connected to the water outlet of the water pump.

[0043] As Figure 1 , Figure 3 and Figure 7 shown, the collection member 53 includes a U-shaped liquid collection tank 532 fixedly connected above the water tank 2 through support legs. Inside the U-shaped liquid collection tank 532, there is a diversion plate 533 fixedly connected. The rear surface of the U-shaped liquid collection tank 532 is fixedly and penetratingly connected with two drain pipes 531 distributed left and right. An electronic valve is arranged on the drain pipe 531. The lower surface of the diversion plate 533 and the U-shaped liquid collection tank 532 are sealed.

[0044] In specific use, the heat shrinkable film passes through the fixed ring 621 and the spray ring 631 and then reaches below the support seat 61, and passes through the diversion plate 533 and enters the interior of the water tank 2. When the heat shrinkable film passes through the diversion plate 533, the used cooling water flowing out from the fixed ring 621 and the linkage 632 drops on the diversion plate 533 and is drained through the diversion plate 533 into the interior of the U-shaped liquid collection tank 532 for storage. When a certain amount of used cooling water is stored in the U-shaped liquid collection tank 532, the electronic valve on the drain pipe 531 is opened to transport the used cooling water stored in the U-shaped liquid collection tank 532 into the interior of the storage tank 51 for storage and cooling.

[0045] After a certain amount of cooling water is stored again inside the emptied loop-shaped liquid collection tank 532, first, the cooling water inside the storage tank 51 is conveyed through the return water pipe 52 to the inside of the winding part 4 by a water pump. When replacing the cooling water inside the water tank 2, the used cooling water is discharged from the drain pipe at the front end of the water tank 2, which can reduce the use of external cooling water and better ensure the temperature of the cooling water inside the water tank 2. After the cooling water inside the storage tank 51 is conveyed into the water tank 2, the electronic valve on the drain pipe 531 is opened again to convey the cooling water inside the loop-shaped liquid collection tank 532 into the storage tank 51. In this cycle, the used cooling water is uniformly collected for reuse, reducing the waste of water resources.

[0046] It should be noted that auxiliary cooling equipment can be installed inside the storage tank 51 according to the cooling requirement to further improve the cooling effect of the cooling water.

[0047] After the heat shrinkable film passes through the fixing ring 621 and the spraying ring 631 and enters the inside of the winding part 4, it changes from a cylindrical shape to a flat shape. The heat shrinkable film is secondarily cooled by the cooling water inside the water tank 2. The heat shrinkable film after secondary cooling is output from the front end of the water tank 2, dried by the drying part 3, and then wound by the winding part 4. The winding part 4 adopts the existing technology and will not be elaborated here.

[0048] Working principle: During specific use, the heat shrinkable film is conveyed in a cylindrical shape to the inside of the first cooling part 62 after blow molding and extrusion. The first cooling part 62 cools and shapes the heat shrinkable film by spraying cooling water. At the same time, the driving part 65 drives the second cooling part 63 to rotate reciprocally in a small distance on the first cooling part 62 in cooperation with the reset part 64, so that the second cooling part 63 undergoes a circumferential displacement during the process of spraying and cooling the heat shrinkable film, enabling the cooling water to fully contact the surface of the heat shrinkable film. The sprayed cooling water flows downward and enters the inside of the collecting part 53 along with the heat shrinkable film. The collecting part 53 separates the used cooling water from the heat shrinkable film and collects it inside the collecting part 53. The heat shrinkable film enters the water tank 2 and changes from a cylindrical shape to a flat shape for secondary cooling. After a certain amount of the separated cooling water is stored inside the collecting part 53, it is conveyed into the storage tank 51 for storage and cooling. The heat shrinkable film after secondary cooling is output from the front end of the water tank 2, dried by the drying part 3, and then wound by the winding part 4.
