Description

Technical Field

[0001] This invention belongs to the field of packaging technology, and in particular relates to a traction-moving film covering mechanism. Background Technology

[0002] For products requiring cleanliness in production, packaging is generally necessary during manufacturing. A common example is the lamination process in paper roll production, where a laminating mechanism covers the surface of the paper roll with stretch film as it passes through a conveyor line. For instance, the existing patent CN202321620483.6 discloses an automatic flattening, unwinding, and cutting laminating machine that utilizes a clamping assembly and a clamping plate assembly to flatten and guide the unwinding of the stretch film, ensuring accurate automatic cutting, neat cut lines, and good packaging lamination results. This laminating machine has a clamping assembly and a clamping plate assembly. While the clamping assembly automatically pulls the stretch film during unwinding, the end of the stretch film is suspended in the air. Simultaneously, the product is also conveyed horizontally, and the stretch film is laid on the product surface. Because the end of the stretch film lacks positioning, it is in a relaxed state on the product, lacking pre-tension. This can lead to misalignment of the stretch film during circumferential secondary lamination. Summary of the Invention

[0003] The purpose of this invention is to solve the aforementioned technical problems by providing a traction-moving film-coating mechanism, thereby accurately positioning the end of the traction-wound film and ensuring accurate film-coating positioning of the product during transportation. To achieve the above objective, the technical solution of this invention is as follows: A traction-moving film coating mechanism includes a support frame structure and a film clamping structure. The support frame structure has a clamping groove for accommodating the film clamping structure. The support frame structure includes several support plates for transfer and a circulating line that is synchronously conveyed on the support plates. The film clamping structure includes a clamping stationary plate and a clamping movable plate that moves relative to and clamps the clamping stationary plate. The clamping movable plate or the clamping stationary plate is used for vacuum adsorption and positioning of the wrapping film.

[0004] Specifically, the membrane structure is installed on the support frame structure, and the membrane structure is arranged perpendicularly to the support frame structure.

[0005] Specifically, connecting components may be provided between adjacent support plates.

[0006] Specifically, the support frame structure also includes a roller assembly located at the bottom of the support plate and a bracket drive assembly located at the bottom of the support plate.

[0007] Specifically, the side of the clamping moving plate or clamping fixed plate is provided with a plurality of clamping adsorption holes.

[0008] Specifically, the clamping fixed plate is disposed on one side of the clamping groove wall, the clamping movable plate is close to the other side of the clamping groove wall, and the support plate is provided with a driving component that connects to the clamping movable plate.

[0009] Specifically, a film-laying mechanism is provided above the traction-moving film-laying mechanism. The film-laying mechanism includes a support roller group for supporting the winding film roll, a pressing roller arranged below the support roller group and vertically movable, and a pressing assembly arranged on the side of the pressing roller and vertically movable.

[0010] Specifically, the film feeding mechanism also includes a frame; the support roller group is disposed on the top of the frame, and the film pressing roller and film pressing assembly are disposed laterally between the two sides of the frame.

[0011] Specifically, the film pressing assembly includes a film pressing beam and a cutting member disposed on the film pressing beam and arranged telescopically; the cutting member is arranged in a transverse direction and along the length direction of the film pressing beam.

[0012] Specifically, the side wall of the pressure beam is provided with a number of pressure adsorption holes, and the pressure beam is provided in a corresponding manner with the clamping groove.

[0013] Compared with the prior art, the beneficial effects of the traction-moving film covering mechanism of the present invention are mainly reflected in: The traction-moving laminating mechanism has the function of traction and positioning the end of the stretch film, and can be applied to different laminating application scenarios. It can be used at the transition position of the product conveyor, and can effectively avoid the end position of the stretch film by using the clamping groove, thereby turning the end of the stretch film to the front or rear of the product. This improves the positioning accuracy of the stretch film and the accuracy of the lamination position on the product. Attached Figure Description

Detailed Implementation

[0015] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0016] Example 1: This embodiment provides a traction-moving laminating mechanism, which is small in size and can be used as a supporting mechanism for the technology described in the background of this application. It effectively pulls and positions the end of the stretch film, ensuring that the stretch film is initially pre-tightened and positioned during product transportation, and that the stretch film is also properly laminating the end of the product. The traction-moving laminating mechanism includes a support frame structure 1 and a film clamping structure 2. The support frame structure 1 supports the product along its transfer path, and the film clamping structure 2 pulls and positions the end of the stretch film. This traction-moving laminating mechanism can be used in conjunction with the automatic flattening, unwinding, and cutting laminating machine described in the background of this application, or it can be used independently, depending on the specific application scenario.

[0017] Reference Figure 1-4 As shown, the conveying direction of the support frame structure 1 is the longitudinal direction, that is, the horizontal direction.

[0018] This embodiment provides a traction-moving film-coating mechanism, including a support frame structure 1 and a film clamping structure 2. The support frame structure 1 is provided with a clamping groove 11 for accommodating the film clamping structure 2. The film clamping structure 2 is arranged perpendicularly to the support frame structure 1, that is, in the transverse direction. The film clamping structure 2 is installed on the support frame structure 1, and the opening and closing clamping action of the film clamping structure 2 does not affect the walking and transferring function of the support frame structure 1.

[0019] The support frame structure 1 includes at least two support plates 12, arranged vertically. A connecting component 13 may be provided between adjacent support plates 12, the connecting component 13 being laterally connected between the support plates 12 for fixing and supporting the support plates 12. The connecting component 13 can be a beam, specifically a solid rod structure, arranged laterally between the support plates 12.

[0020] The support frame structure 1 also includes a circulation line 14 synchronously conveyed on the support plate 12, a roller assembly disposed at the bottom of the support plate 12, and a bracket drive assembly 16 disposed at the bottom of the support plate 12. The circulation line 14 is used to horizontally transfer and convey the product, the roller assembly enables the overall support frame structure 1 to have a transfer function, and the bracket drive assembly 16 drives the roller assembly, thereby moving the support frame structure 1.

[0021] The film clamping structure 2 includes a clamping fixed plate 21 and a clamping movable plate 22 that moves relative to and clamps the clamping fixed plate 21. A vacuum adsorption effect exists between the clamping movable plate 22 and the clamping fixed plate 21, specifically, the side of the clamping movable plate 22 or the clamping fixed plate 21 is provided with several film clamping adsorption holes. These adsorption holes exert an adsorption force on the stretch film, allowing it to be pulled and positioned within the film clamping structure 2. The film clamping structure 2 clamps and positions the stretch film without affecting the normal transfer of the support frame structure 1. In this embodiment, the film clamping structure 2 is arranged perpendicularly to the arrangement direction of the support frame structure 1. When the stretch film enters the clamping groove 11, it is positioned within the film clamping structure 2. As the support frame structure 1 transfers the product above the clamping groove 11, the end of the stretch film is in a traction state and pushed by the end face of the product. The film clamping structure 2 releases the stretch film, which is now in place against the end face of the product, improving the positioning accuracy of the stretch film and the compactness of the product wrapping.

[0022] Example 2: This embodiment optimizes the traction-moving film-coating mechanism based on the above embodiments, and in particular provides a specific implementation of the support frame structure 1: Reference Figure 3-4 As shown, the support plate 12 can be a flat plate, and the support plates 12 are arranged parallel to each other. The number of support plates 12 can be two or more. This embodiment takes two support plates as an example. The number of support plates 12 is related to the size of the product to be conveyed. Several support plates 12 arranged at suitable intervals are selected to stably support the product.

[0023] Synchronous circulation lines 14 are respectively provided on the top of the support plates 12 on both sides. Since the support plates 12 have clamping grooves 11 with their openings facing vertically upwards, the clamping grooves 11 separate the support plates 12 on one side, and the clamping grooves 11 on both sides of the support plates 12 are symmetrically arranged. The circulation lines 14 are distributed on the support plates 12 located on both sides of the clamping grooves 11. To achieve synchronous driving of the circulation lines 14 on both sides, two drive shafts 17 are provided between the support plates 12 on both sides. The two drive shafts 17 are connected to a bracket drive assembly 16, allowing the two drive shafts 17 to rotate synchronously. The bracket drive assembly 16 can be a hydraulic drive, a pneumatic drive, or an electric drive. In this embodiment, the bracket drive assembly 16 includes a motor. Each drive shaft 17 is connected to the corresponding position of the circulation line 14 via a transition belt, thereby achieving synchronous driving of the circulation line 14 by the two drive shafts 17, and realizing stable movement of the products on the circulation line 14.

[0024] The support frame structure 1 is usually set at the transition position between two horizontal conveyor lines. The product is conveyed from the horizontal conveyor line, transferred through the support frame structure 1, and initially wrapped and positioned by the wrapping film at the support frame structure 1.

[0025] At least two roller assemblies are provided between the support plates 12 on both sides. Each roller assembly includes a connecting shaft 18, which is connected to a bracket drive assembly 16, allowing the two connecting shafts 18 to rotate synchronously. Rollers are provided at both ends of each connecting shaft 18. A track is provided below the support frame structure 1, and the rollers slide along the track. The support frame structure 1 moves horizontally in the longitudinal direction, driven by the two roller assemblies, enabling it to slide smoothly on the track.

[0026] Example 3: This embodiment optimizes the traction-moving film-coating mechanism based on the above embodiments, and in particular provides a specific implementation of the film-coating structure 2: Reference Figure 3-4 As shown, the clamping fixed plate 21 is disposed on the support plate 12, specifically on one side wall of the clamping groove 11, and the clamping movable plate 22 is close to the other side wall of the clamping groove 11. The support plate 12 is provided with a driving component connecting the clamping movable plate 22, which can be a hydraulic, pneumatic, or electric driving component; in this embodiment, the driving component is a cylinder. This allows the clamping movable plate 22 to extend and retract relative to the clamping fixed plate 21, and the clamping fixed plate 21 and the clamping movable plate 22 can clamp and position the end of the wrapping film.

[0027] The clamping moving plate 22 has several film adsorption holes on its side relative to the clamping fixed plate 21. The inner cavity of the clamping moving plate 22 is connected to several film adsorption holes. The several film adsorption holes have a vacuum adsorption function. When the wrapping film is attached to the clamping moving plate 22, it is vacuum adsorbed by the several film adsorption holes, and the wrapping film is not easy to fall off the clamping moving plate 22.

[0028] Example 4: This embodiment, based on the above embodiment, provides a specific implementation of the film-laying mechanism 3 by setting a film-laying mechanism above the traction-moving film-laying mechanism: Reference Figure 5 As shown, the film feeding mechanism 3 includes a support roller group 31 for supporting the stretch film roll, a pressure roller 32 disposed below the support roller group 31 and arranged for vertical movement, and a pressure assembly 33 disposed on the side of the pressure roller 32 and arranged for vertical movement. The stretch film roll is released and passes through the pressure roller 32 and the pressure assembly 33. When the product moves horizontally normally on the conveyor line, the pressure roller 32 descends and presses the stretch film onto the product. At this time, the pressure assembly 33 is in the upper position. When the film feeding mechanism 3 needs to cooperate with the traction and movement of the coating mechanism, the pressure assembly 33 is in the lower position and performs traction and cutting of the stretch film.

[0029] The film-laying mechanism 3 also includes a frame 34. The film-pressing roller 32, film-pressing assembly 33, and support roller group 31 are all mounted on the frame 34. Specifically, the support roller group 31 is located at the top of the frame 34, and the film-pressing roller 32 and film-pressing assembly 33 are arranged laterally between the two sides of the frame 34. Both the film-pressing roller 32 and film-pressing assembly 33 are connected to lifting drive components. The lifting drive components for the film-pressing roller 32 and film-pressing assembly 33 can be the same or different. The lifting drive components enable the independent lifting and lowering movements of the film-pressing roller 32 and film-pressing assembly 33. The lifting drive components can be either a motor-driven chain and slide rail structure or a cylinder-driven chain and slide rail structure.

[0030] The film-pressing assembly 33 includes a film-pressing beam 35 and a cutting member 36 disposed on the film-pressing beam 35 and arranged telescopically. The cutting member 36 is arranged laterally and along the length of the film-pressing beam 35. A driving member connecting the cutting member 36 is provided on the film-pressing beam 35. The driving member can be of various types; in this embodiment, it is a cylinder. In its normal state, the cutting member 36 is retracted to the side of the film-pressing beam 35. When the cutting member 36 needs to perform a cutting operation, it extends out from the side of the film-pressing beam 35 to cut the stretch film.

[0031] The pressure beam 35 has several pressure adsorption holes on its sidewalls, and these holes also extend through the inner cavity of the pressure beam 35. These pressure adsorption holes provide vacuum adsorption and are located on the sidewalls of the pressure beam 35 away from the cutting component 36. When the wrapping film passes over the pressure assembly 33, it is adsorbed on one side of the pressure beam 35 and cut on the other side. The pressure beam 35 corresponds to the clamping groove 11. The pressure beam 35 presses the wrapping film into the clamping groove 11, transferring it to the clamping structure 2. The pressure beam 35 then releases the vacuum adsorption force and exits the clamping groove 11 normally. The wrapping film is then positioned within the clamping structure 2, achieving end-end traction and positioning.

[0032] When applying this embodiment four, in conjunction with the traction moving film coating mechanism, the product is normally horizontally conveyed to the traction moving film coating mechanism. The film pressing beam 35 brings the wrapping film into the traction moving film coating mechanism, which plays a role in adsorbing and positioning the end of the wrapping film, thereby applying a pre-tightening force to the front or rear end of the product, improving the positioning accuracy of the wrapping film and the position accuracy of the film on the product.

[0033] The traction-moving film coating mechanism has the function of traction and positioning of the end of the wrapping film, and can be applied to different film coating application scenarios. It can be used at the conveying transition position of the product, and the clamping groove 11 can effectively avoid the end position of the wrapping film, thereby turning the end of the wrapping film to the front or rear of the product.
