Description

Technical Field

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

[0002] Heat shrink film is a plastic film that can shrink and tightly wrap objects under heating conditions. It is widely used in the packaging field of food, medicine, electronics, and daily necessities industries. During production, the raw materials pass through the film blowing machine to form a cylindrical heat shrink film, which passes through the cooling cylinder. 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 the water tank for secondary cooling. After the heat shrink film enters the water tank, it changes from a cylindrical shape to a flat shape. After being output from the water tank, it is dried and rolled into a heat shrink film roll.

[0003] The heat shrink film is cooled during the transportation process. When the heat shrink film passes through the cooling cylinder, the heat shrink film is in a tubular structure and is filled with air. At this time, the surface of the heat shrink film fits with the inner surface of the cooling cylinder. In 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 cooling water, resulting in insufficient contact between the cooling water and the heat shrink film, affecting the cooling and shaping effect of the heat shrink film. The used cooling water directly enters the water tank below, causing the cooling water inside the water tank to mix with the used cooling water. The temperature of the used cooling water increases. After mixing with the cooling water inside the water tank, it affects the cooling effect of the cooling water in the water tank on the heat shrink film. Summary of the invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth 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 violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

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

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

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, cooling member 1 62 includes multiple fixed rings 621 evenly distributed in the up-down direction, a through hole is provided on the upper surface of the support seat 61 at the position corresponding to the fixed ring 621, and multiple evenly distributed brackets 622 are fixedly connected together on the outer circumferential surfaces of two adjacent fixed rings 621, and cooling member 2 63 includes multiple spray rings 631 evenly distributed in the up-down direction, a spray ring 631 is rotatably connected between two adjacent fixed rings 621, an overflow groove 623 is provided on the inner circumferential surface of the fixed ring 621 between two adjacent spray rings 631, and a water supply pipe 1 624 is fixed together and penetrated on the outer circumferential surfaces of the multiple fixed rings 621.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, the width of the top and bottom fixing rings 621 among the multiple fixing rings 621 distributed up and down is smaller than the width of the middle fixing ring 621, and the outer circumferential surfaces of the multiple fixing rings 621 with overflow grooves 623 are fixed together and penetrated by a water supply pipe 624, and an auxiliary roller is provided on the side of the bracket 622 close to the spray ring 631, and the auxiliary roller changes the sliding friction between the bracket 622 and the spray ring 631 into rolling friction.

[0034] During specific use, the heat shrinkable film is blow-molded and extruded and then transported to the inside of the fixed ring 621 in a cylindrical shape. After passing through multiple fixed rings 621, the heat shrinkable film passes through the through holes on the support seat 61 and is transported to the bottom of the support seat 61. When the heat shrinkable film passes through the fixed ring 621, cooling water is continuously transported to the inside of the overflow groove 623 through a water supply pipe 624 on the fixed ring 621. As the cooling water is continuously transported, the cooling water overflows from the inside of the overflow groove 623. At this time, since the heat shrinkable film is attached to the inner circumference of the fixed ring 621, the overflowing cooling water adheres to the surface of the heat shrinkable film, thereby cooling the heat shrinkable film.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, multiple uniformly distributed linkage frames 632 are commonly fixedly connected to the outer circumferential surfaces of multiple spray rings 631, and a water supply pipe 633 is commonly fixed and penetrated through the outer circumferential surfaces of multiple spray rings 631. Multiple nozzles are uniformly distributed on the inner circumferential surface of the spray ring 631, and there is a certain distance between the water spraying end of the nozzle and the inner surface of the fixed ring 621, and a section of hose is arranged in the middle position of the water supply pipe 633.

[0036] During specific use, when the heat shrink film passes through the fixed ring 621, cooling water is transported to the inside of the spray ring 631 through the water supply pipe 633, and the cooling water is sprayed out through the nozzle on the spray ring 631 to cool down the heat shrink film. At the same time, the gap reserved between the water spraying end of the nozzle and the inner surface of the fixed ring 621 can ensure that the cooling water sprayed out by the nozzle has sufficient space to contact the heat shrink film, so that the amount of cooling water in contact with the heat shrink film is larger, so as to better cool and shape the heat shrink film. At the same time, the spray ring 631 is driven by the driving member 65 to perform a small distance reciprocating rotation on the fixed ring 621, so that the cooling water sprayed out from the nozzle on the spray ring 631 can more fully cover the surface of the heat shrink film passing through the nozzle.

[0037] like Figure 2 and Figure 5As shown, the reset member 64 includes two upper and lower symmetrical annular rails 641 fixedly connected to the cooling member 62, and connecting grooves are provided on the opposite back surfaces of the two annular rails 641. The inner parts of the connecting grooves are slidably connected with sliding blocks 642 at positions corresponding to the linkage frame 632. The upper surfaces of the sliding blocks 642 and the linkage frame 632 are jointly fixedly connected with a linkage plate 643. A fixed block 644 is fixedly connected to the inner part of the connecting groove and on one side of the sliding block 642, and a connecting spring is arranged between the sliding block 642 and the fixed block 644.

[0038] like 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 seat 61, the top of the fixed seat 651 is fixedly connected to a mounting sleeve 652, the inner part of the mounting sleeve 652 is rotatably connected to an outer gear ring 653, and the inner circumferential surface of the outer gear ring 653 is fixedly connected to a position corresponding to the linkage frame 632, and the end of the elastic connecting seat 654 facing the center of the mounting sleeve 652 is fixedly connected to a wedge-shaped push block 655.

[0039] like Figure 2 and Figure 6 As shown, the outer gear ring 653 is embedded in the interior of the mounting sleeve 652, and the outer gear ring 653 is coaxial with the mounting sleeve 652, the wedge-shaped push block 655 slides with its corresponding linkage frame 632, and a driving motor is fixedly installed on the rear side of the upper surface of the support seat 61 through a motor seat, and a driving gear is fixedly connected to the output shaft of the driving motor, and an opening for exposing the teeth of the outer gear ring 653 is provided at the position corresponding to the driving gear on the mounting sleeve 652, and the driving gear is meshed with the outer gear ring 653. When the elastic connecting seat 654 is in a normal state, when the wedge-shaped push block 655 passes through the linkage frame 632, the inclined surface of the wedge-shaped push block 655 is attached to the linkage frame 632, and the elastic force of the elastic connecting 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 friction force between the fixed ring 621 and the spray ring 631.

[0040] During specific use, the driving motor drives the outer gear ring 653 to rotate continuously inside the mounting sleeve 652 through the driving gear thereon, and the outer gear ring 653 drives the wedge-shaped push block 655 to rotate continuously through the elastic connecting seat 654. When the wedge-shaped push block 655 rotates to contact with the linkage frame 632, the linkage frame 632 generates resistance to the wedge-shaped push block 655, and the wedge-shaped push block 655 pushes the linkage frame 632 to rotate, and 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 frame 632 rotates to the position of the bracket 622, the bracket 622 limits the linkage frame 632. As the outer gear ring 653 continues to rotate, the inclined surface of the wedge-shaped push block 655 slides on the linkage frame 632 and compresses the elastic connecting seat 654. When the outer gear ring 653 drives the wedge-shaped push block 655 to pass over the linkage frame 632 contacted at this time through the elastic connecting seat 654, the wedge-shaped push block 655 is restored to its original position under the action of the elastic force of the elastic connecting seat 654 itself. At the same time, under the action of the elastic force of the connecting spring itself, the linkage frame 632 is driven to return to its original position through the sliding block 642. As the outer gear ring 653 continues to rotate, when the outer gear ring 653 drives the wedge-shaped push block 655 to pass the next linkage frame 632, the above steps are repeated to continue to drive the linkage frame 632 to rotate a certain distance, thereby realizing that the linkage frame 632 drives the spray ring 631 to reciprocate a small distance on the fixed ring 621.

[0042] like Figure 1 and Figure 7 As shown, the collecting mechanism 5 includes a storage box 51 fixedly connected to the upper surface of the base 1, a return pipe 52 is fixedly connected to the rear surface of the water tank 2 and penetrates through it, a collecting member 53 is arranged above the water tank 2, and the end of the return pipe 52 away from the water tank 2 is connected to the interior of the storage box 51, and a water pump (not shown in the figure) is arranged inside the storage box 51, and the return pipe 52 is connected to the interior of the storage box 51 and is fixedly connected to the water outlet of the water pump.

[0043] like Figure 1 , Figure 3 and Figure 7 As shown, the collecting member 53 includes a circular liquid collecting trough 532 fixedly connected to the top of the water tank 2 by supporting legs, a guide plate 533 is fixedly connected to the inner side of the circular liquid collecting trough 532, and two drainage pipes 531 distributed on the left and right are fixed and penetrated on the rear surface of the circular liquid collecting trough 532, an electronic valve is arranged on the drainage pipe 531, and a sealing arrangement is formed between the lower surface of the guide plate 533 and the circular liquid collecting trough 532.

[0044] During specific use, the heat shrink film passes through the fixed ring 621 and the spray ring 631 to the bottom of the support seat 61, passes through the guide plate 533 and enters the interior of the water tank 2. When the heat shrink film passes through the guide plate 533, the used cooling water flowing out from the fixed ring 621 and the linkage frame 632 along with the heat shrink film falls on the guide plate 533, and is drained to the interior of the meandering liquid collecting groove 532 through the guide plate 533, and is stored in the meandering liquid collecting groove 532. When a certain amount of used cooling water is stored in the meandering liquid collecting groove 532, the electronic valve on the drain pipe 531 opens, and the cooling water stored in the meandering liquid collecting groove 532 is transported to the interior of the storage box 51 for storage and cooling.

[0045] After a certain amount of cooling water is stored again inside the emptied circular liquid collecting tank 532, the cooling water inside the storage box 51 is first transported to the inside of the winding section 4 through the return pipe 52 by a water pump. When the cooling water inside the water tank 2 is replaced, 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 box 51 is transported to the inside of the water tank 2, the electronic valve on the drain pipe 531 is opened again to transport the cooling water inside the circular liquid collecting tank 532 to the inside of the storage box 51, thereby circulating the used cooling water and collecting it for reuse, thereby reducing the waste of water resources.

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

[0047] After the heat shrink film passes through the fixing ring 621 and the spray ring 631 and enters the interior of the winding section 4, it changes from a cylindrical shape to a flat shape, and the heat shrink film is secondary cooled by the cooling water in the water tank 2. The secondary cooled heat shrink film is output from the front end of the water tank 2, dried by the drying section 3, and then wound by the winding section 4. The winding section 4 adopts the existing technology, which will not be described in detail here.

[0048] Working principle: During specific use, the heat shrink film is extruded by blow molding and transported to the interior of cooling member 1 62 in a cylindrical shape. Cooling member 1 62 cools and shapes the heat shrink film by spraying cooling water. At the same time, driving member 65 drives cooling member 2 63 to cooperate with reset member 64 on cooling member 1 62 to rotate back and forth in a small distance, so that cooling member 2 63 is displaced circumferentially during the process of spraying and cooling the heat shrink film, so that the cooling water can fully contact the surface of the heat shrink film, and the sprayed cooling water flows downward, and as the heat shrink film flows into the interior of collecting member 53, collecting member 53 separates the used cooling water from the heat shrink film and collects them in the interior of collecting member 53. The heat shrink film enters the interior of water tank 2 and changes from cylindrical to flat for secondary cooling. After a certain amount of separated cooling water is stored in the interior of collecting member 53, it is transported to the interior of storage box 51 for storage and cooling. The heat shrink film that has been cooled for the secondary time is output from the front end of water tank 2, dried by drying section 3, and then rolled up by winding section 4.
