Description

Technical Field

[0001] This utility model belongs to the field of heat shrink film production and processing technology, and specifically relates to a folding device for heat shrink film production. Background Technology

[0002] Heat shrink film is widely used in the packaging industry. It has high puncture resistance, good shrinkage and certain shrinkage stress, and can stabilize, cover and protect the wrapped items. In the production process of heat shrink film, in order to improve its service life and tensile strength, the edges of the film usually need to be folded and thickened. However, during the production process, different customers have different requirements for the width of heat shrink film. If the equipment cannot adjust the width, the company can only fold the edges of heat shrink film with a fixed width, which cannot meet the diverse market demands.

[0003] According to the public announcement (CN217021408U), a folding device for a heat shrink film production line is disclosed. This technology discloses that "it includes a base and an embedding groove. The embedding groove is embedded in the center of the upper surface of the base. A pressing mechanism is installed on the upper surface of the base. A winding mechanism is fixedly installed at the bottom of the right side surface of the base. The pressing mechanism includes a concave bracket, an electric telescopic rod, a lifting block, a pressure roller, a rotary motor, a connecting plate, and other technical solutions, which have the technical effect of facilitating the extrusion of heat shrink composite films of different thicknesses."

[0004] In this existing design, due to the different requirements of different customers for the width of heat shrink film, the existing technology cannot adjust the size of the folding edge. For folding edges of heat shrink film of different widths, enterprises may need to purchase multiple sets of folding devices of different specifications, which undoubtedly increases the equipment procurement cost. Frequent replacement of folding devices or parts will significantly reduce production efficiency and is also not conducive to diversified production of equipment, thus reducing the practicality of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1: As Figure 1 As shown;

[0035] A folding device for heat shrink film production includes a support 1 and a rolling roller 11 disposed on the surface of the support 1.

[0036] In this implementation scheme: In the prior art, the support 1 and the pressing roller 11 are used to complete the folding of the heat shrink film. For the specific working principle of the support 1 and the pressing roller 11, please refer to the technology disclosed in "CN217021408U discloses a folding device for a heat shrink film production line". This technology discloses that "by setting a pressing mechanism, the pressing roller can be raised and lowered by driving the lifting block through the first electric telescopic rod, thereby facilitating the adjustment of the distance between the pressing roller and the embedding groove, facilitating the extrusion of heat shrink composite films of different thicknesses, and after the pressing roller extrudes the heat shrink composite film, it will be embedded in the annular groove, so that the base film is thicker on both sides and thicker in the middle". "Thin state", however, in this existing design, due to the different requirements of different customers for the width of heat shrink film, this existing technology cannot adjust the size of the folding edge. For the folding edge of heat shrink film of different widths, enterprises may need to purchase multiple sets of folding devices of different specifications, which undoubtedly increases the equipment procurement cost. Frequent replacement of folding devices or components will significantly reduce production efficiency, and will also be detrimental to the diversified production of equipment, reducing the practicality of the equipment. In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, adjustment component 2 and compaction component 3 are added to this application.

[0037] Furthermore:

[0038] As Figures 1 to 3 shown:

[0039] Combined with the above: A hemming device for heat shrinkable film production further includes an adjustment component 2 provided on the surface of the bracket 1;

[0040] The adjustment component 2 includes a transmission mechanism 4 fixed on the surface of the bracket 1. A base 21 is fixedly connected to the surface of the bracket 1. A right slider 22 and a left slider 23 are symmetrically arranged on the surface of the base 21. A bidirectional threaded rod 24 is rotatably connected to the surface of the bracket 1. The right slider 22 and the left slider 23 are symmetrically threadedly connected to the surface of the bidirectional threaded rod 24. One ends of the right slider 22 and the left slider 23 close to the bracket 1 are fixedly connected with hemming blocks 25, and the first rolling roller 11 is installed on the surface of the hemming blocks 25.

[0041] In this implementation: When a new size-width heat shrinkable film needs to be produced, the workshop staff rotates the bidirectional threaded rod 24 to drive the right slider 22 and the left slider 23 to move towards or away from each other on the surface of the base 21, thereby changing the distance between the two hemming blocks 25. Then the staff installs a suitable first rolling roller 11 on the surface of the hemming blocks 25 to fix the heat shrinkable film, and the hemming blocks 25 realize hemming of heat shrinkable films with different widths. After the adjustment is completed, the staff transports the heat shrinkable film on the surface of the transmission mechanism 4 to provide the function of material transportation for subsequent hemming operations.

[0042] It should be noted that: The transmission mechanism 4 is composed of a motor, a pulley, a frame, etc. The staff can also adopt the transmission method with the "Publication (Announcement) Number: "CN217075990U" in the prior art according to actual needs, which will not be described one by one here.

[0043] Furthermore:

[0044] As Figures 1 to 3 shown:

[0045] In an optional embodiment, the right slider 22 and the left slider 23 are in a "C" shape.

[0046] In this embodiment: The "C" shape design can make the right slider 22 and the left slider 23 slide more stably on the surface of the base 21, and at the same time, the hemming blocks 25 can be firmly fixed on the surfaces of the right slider 22 and the left slider 23.

[0047] Furthermore:

[0048] As Figure 2 shown:

[0049] In an optional embodiment, sliders 26 are symmetrically fixedly connected to the surfaces of both the right slider 22 and the left slider 23, and the surface of the base 21 is provided with a groove 27 that mates with slider 26.

[0050] In this embodiment: when the right slider 22 and the left slider 23 slide on the surface of the base 21, they drive the slider 26 to slide on the surface of the groove 27, guiding the sliding trajectory of the right slider 22 and the left slider 23 and limiting their position, so that the right slider 22 and the left slider 23 can accurately perform relative or opposite movements under the drive of the bidirectional threaded rod 24, thereby achieving precise adjustment of the position of the folded edge block 25.

[0051] Furthermore:

[0052] like Figure 4 and Figure 5 As shown:

[0053] In an optional embodiment, a guide block 28 is fixedly connected to the surface of the folding block 25, and an arc-shaped folding groove 29 is formed on the surface of the guide block 28.

[0054] In this embodiment: the guide block 28 guides the movement direction of the heat shrink film after folding, and the arc-shaped folding groove 29 is used to guide the heat shrink film to fold, so that when the heat shrink film passes through the folding device, it will bend along the contour of the arc-shaped folding groove 29, thereby ensuring that the angle and shape of the folding are uniform and consistent, and improving the flatness and aesthetics of the folding.

[0055] Furthermore:

[0056] like Figure 5 As shown:

[0057] In an optional embodiment, the surface of the guide block 28 is provided with a straight groove 210, and the straight groove 210 is connected to the arc-shaped folded edge groove 29.

[0058] In this embodiment: after the heat shrink film is folded, the straight groove 210 helps to maintain the shape of the heat shrink film after folding, and at the same time assists in subsequent compaction, it can also play the role of auxiliary guidance and feeding.

[0059] Furthermore:

[0060] like Figure 6 As shown:

[0061] In an optional embodiment, one end of the bidirectional threaded rod 24 is fixedly connected to a handle 211, and the surface of the handle 211 is engraved with anti-slip texture.

[0062] In this embodiment, the operator can control the bidirectional threaded rod 24 through the handle 211. The anti-slip texture engraved on the surface makes it easier for the operator to manually rotate the bidirectional threaded rod 24, thereby facilitating the operator to adjust the width of the folded edge of the equipment.

[0063] Furthermore:

[0064] like Figure 6 As shown:

[0065] In an optional embodiment, a compaction component 3 is also included on the surface of the base 21;

[0066] The compaction assembly 3 includes a slide plate 31 disposed on the surface of the base 21, a connecting rod 32 fixedly connected to the surface of the slide plate 31, a mounting frame 33 fixedly connected to the surface of the connecting rod 32, and a rolling roller 34 connected to the rotating rod of the mounting frame 33.

[0067] In this implementation scheme: the heat shrink film after folding is conveyed by the conveying mechanism 4 and compacted by the rolling roller 34, which can make the heat shrink film at the folded edge fit tightly, maintain the shape of the folded edge, make the folded edge of the heat shrink film tighter, reduce gaps and holes, thereby enhancing the sealing performance of the packaging.

[0068] Furthermore:

[0069] like Figure 7 As shown:

[0070] In an optional embodiment, a right connecting rod 35 is rotatably connected to the surface of the right slider 22, and a left connecting rod 36 is rotatably connected to the surface of the left slider 23. The end of the right connecting rod 35 away from the right slider 22 is rotatably connected to the end of the left connecting rod 36 away from the left slider 23. The left connecting rod 36 is rotatably connected to the surface of the left slider 23. Connecting rods 32 are rotatably connected to the ends of the right connecting rod 35 and the left connecting rod 36 away from the left slider 23. A second sliding groove is provided on the surface of the base 21, and the slide plate 31 is slidably connected to the base 21 through the second sliding groove.

[0071] In this embodiment: when the right slider 22 and the left slider 23 move, they drive the right connecting rod 35 and the left connecting rod 36 to move. Since the right connecting rod 35 and the left connecting rod 36 form a triangular relationship with the base 21, when the right slider 22 and the left slider 23 move towards or away from each other, the end of the right connecting rod 35 away from the right slider 22 and the end of the left connecting rod 36 away from the left slider 23 drive the connecting rod 32 away from or towards the base 21, thereby driving the slide plate 31 to slide on the surface of the base 21 through the second sliding groove. This ensures that the connecting rod 32 is always in the center position of the base 21. While adjusting the folding width, the position of the second pressing roller 34 is automatically adjusted to ensure that the second pressing roller 34 can effectively compact the heat shrink film after folding with different widths, simplifying the operation process and improving production efficiency.

[0072] Furthermore:

[0073] like Figure 8 As shown:

[0074] In an optional embodiment, a plurality of balls 37 are rotatably connected to the surface of the slide plate 31, and an arc-shaped groove 38 that cooperates with the balls 37 is provided on the surface of the base 21, and the arc-shaped groove 38 is connected to the groove 2.

[0075] In this embodiment: when the slide plate 31 slides on the surface of the base 21 through the second slide groove, it drives the ball bearing 37 to roll on the surfaces of the slide plate 31 and the base 21, which reduces the frictional resistance when the slide plate 31 slides, making the sliding process of the slide plate 31 smoother.

[0076] Working principle: When a new size and width of heat shrink film needs to be produced, the workshop staff controls the bidirectional threaded rod 24 through the handle 211. The rotation of the bidirectional threaded rod 24 drives the right slider 22 and the left slider 23 to move towards or away from each other on the surface of the base 21. When the right slider 22 and the left slider 23 slide on the surface of the base 21, they drive the slider 26 to slide on the surface of the groove 27. The sliding trajectory of the right slider 22 and the left slider 23 is guided and their positions are limited, so that the right slider 22 and the left slider 23 accurately move towards or away from each other under the drive of the bidirectional threaded rod 24, thereby achieving precise adjustment of the position of the folding block 25, thus changing the two The distance between the folding blocks 25 is determined, and then the operator installs a suitable rolling roller 11 on the surface of the folding block 25 to fix the heat shrink film. The folding block 25 folds heat shrink films of different widths. After adjustment, the operator places the heat shrink film on the surface of the conveying mechanism 4 for transport, providing material transport for subsequent folding operations. After the operation of the rolling roller 11 and the folding block 25, the heat shrink film is transported to the guide block 28 by the conveying mechanism 4. The guide block 28 guides the movement direction of the heat shrink film after folding. The arc-shaped folding groove 29 is used to guide the heat shrink film to fold, so that the heat shrink film will move along the folding device. The contour of the arc-shaped folding groove 29 is curved to ensure that the angle and shape of the fold are uniform, improving the flatness and aesthetics of the fold. After the heat shrink film is folded, the straight groove 210 helps maintain the shape of the heat shrink film after folding, assisting in subsequent compaction while also serving as an auxiliary guide and feeder. When the right slider 22 and the left slider 23 move, they drive the right connecting rod 35 and the left connecting rod 36 to move. Because the right connecting rod 35 and the left connecting rod 36 form a triangular relationship with the base 21, when the right slider 22 and the left slider 23 move towards or away from each other, the end of the right connecting rod 35 away from the right slider 22 and the end of the left connecting rod 36 away from the left slider 23 drive... The connecting rod 32 moves away from or near the base 21, thereby driving the sliding plate 31 to slide on the surface of the base 21 through the second sliding groove. This ensures that the connecting rod 32 is always in the center position of the base 21. While adjusting the fold width, the position of the second pressing roller 34 is automatically adjusted to ensure that the second pressing roller 34 can effectively compact the heat shrink film after folding at different widths. This simplifies the operation process and improves production efficiency. The folded heat shrink film is conveyed by the transmission mechanism 4 and compacted by the second pressing roller 34, which can make the heat shrink film at the fold fit tightly and maintain the shape stability of the fold. This can make the fold of the heat shrink film tighter, reduce gaps and holes, and thus enhance the sealing performance of the packaging.

[0077] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
