Description

Technical Field

[0001] The present application relates to the technical field of end sealing devices, and in particular to a packaging bag clip chain installation device. Background Art

[0002] The sealing zipper is a common sealing structure on packaging bags. During use, the two sides of the zipper are nested and connected with each other to seal the bag opening.

[0003] The installation of the packaging bag clip chain usually requires separating the two layers of film through a guide roller, and extending the outer clip chain between the two separated film sheets through a reversing roller. The two film sheets and the clip chain are then moved together to the heat sealing device under the traction of a traction roller to heat seal the clip chain. In traditional packaging bag installation equipment, the guide of the clip chain can only extend between the two packaging films from a specific position, and the position of the clip chain for heat sealing between the two packaging films cannot be adjusted in time, and the requirements of different installation processes cannot be adapted in time.

[0004] In response to the above-mentioned related problems, the inventor proposes a packaging bag clamp chain installation device. Utility Model Content

[0005] In order to timely adjust the position of the clip chain between two layers of packaging film during the installation of the clip chain of the packaging bag, the present application provides a packaging bag clip chain installation device, which adopts the following technical solution:

[0006] A packaging bag clamp chain installation device includes a frame, a sliding conveyor belt slidably connected to the frame, a wire-releasing drum arranged on one side of the frame, a sliding plate slidably connected to the frame, and two reversing plates fixed to the frame. A wire-releasing hole for the clamp chain to pass through is opened at one end of the sliding plate. The two reversing plates are arranged opposite to each other and are arranged directly below the sliding plate. The conveyor belt and the sliding plate both slide along the width direction of the frame. A sliding component for controlling the sliding of the conveyor belt is arranged on the frame.

[0007] By adopting the above technical scheme, the reversing plate can straighten the clamp chain released by the wire-paying drum to prevent the clamp chain from being tangled, and the clamp chain is further transported to the heat-sealing device for heat-sealing with the packaging film to form defective products, thereby improving the yield rate; the sliding conveyor belt and the sliding plate both slide along the width direction of the frame, and the positions of the conveyor belt and the sliding plate are adjusted so that the position of the wire-paying hole on the sliding plate adapts to the position of the conveyor belt, and the position of the clamp chain relative to the upper and lower layers of packaging film is adjusted in time, which can flexibly adapt to the requirements of various clamp chain installation processes and is convenient and quick.

[0035] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0036] This embodiment discloses a packaging bag clip chain installation device, which is used to install clip chains during the packaging bag manufacturing process. Figure 1 As shown, it includes a frame 1, a capping device 2 fixed to the upper side of the frame 1, a heat sealing device 3 fixed to the upper side of the frame 1, a wire-releasing assembly 4, a tensioning double roller 6 arranged on one side of the wire-releasing assembly 4 and a sliding assembly 5 for adjusting the position of the clamp chain, and the sliding assembly 5 is arranged between the heat sealing device 3 and the pressing device.

[0037] A plurality of guide rollers and traction rollers for separating the upper and lower layers of packaging film are rotatably connected on both sides of the inner wall of the frame 1. The wire-releasing component 4 allows the clamp chain to enter between the upper and lower layers of packaging film and move with the two layers of packaging film and finally enter the heat-sealing device 3. The heat-sealing device 3 contains a component for heat-sealing the clamp chain and the packaging film. The heat-sealing component heat-seales the upper side of the clamp chain and the upper packaging film, and the heat-sealing device 3 heat-seales the lower side of the clamp chain and the lower packaging film.

[0038] like Figure 1 and Figure 2 As shown, the wire-paying assembly 4 includes a wire-paying drum 41 and a guide bucket 42. The wire-paying drum 41 is placed on the ground on one side of the frame 1, and the guide bucket 42 is arranged directly above the wire-paying drum 41. The inner wall of the guide bucket 42 facing the wire-paying drum 41 is bucket-shaped, a through hole is provided at the top of the guide bucket 42, and an outer wall of one side of the guide bucket 42 is fixedly connected to the frame 1.

[0039] The wire-releasing assembly 4 further includes a sliding plate 43 slidably connected to the frame 1 and two reversing plates 44 fixed to the frame 1. The sliding plate 43 is arranged on one side of the frame 1 close to the guide bucket 42 and penetrates the frame 1. A wire-releasing hole 431 is provided at one end of the sliding plate 43. A bolt 432 is threadedly connected to the frame 1. Tightening the bolt 432 and pressing against the sliding plate 43 can limit the movement of the sliding plate 43. The two reversing plates 44 are arranged directly below the sliding plate 43. The clamp chain passes between the two reversing plates 44, and the clamp chain cannot be twisted between the two reversing plates 44.

[0040] The clip chain is released from the pay-off drum 41, passes through the guide bucket 42 and the pay-off hole 431, passes between the two reversing plates 44 and enters between the two layers of packaging films. The two reversing plates 44 straighten the clip chain and then release it.

[0041] like Figure 3 and Figure 4As shown, the sliding assembly 5 includes a conveyor belt 51, two fixed rollers 52 fixedly connected to both sides of the frame 1, and a threaded screw 54 passing through the inner walls on both sides of the frame 1, the length direction of the threaded screw 54 is parallel to the length direction of the fixed roller 52, the length direction of the conveyor belt 51 is perpendicular to the length direction of the fixed roller 52, and a plurality of strip protrusions 521 are fixedly connected to the outer wall of each fixed roller 52, the length direction of the strip protrusion 521 is parallel to the length direction of the fixed roller 52, and the plurality of strip protrusions 521 are evenly arranged on the outer wall of the fixed roller 52.

[0042] One end of the conveyor belt 51 is sleeved on a fixed roller 52, and the other end of the conveyor belt 51 is sleeved on another fixed roller 52. The inner walls of both ends of the conveyor belt 51 are provided with strip grooves (not shown in the figure) that can cooperate with the strip protrusions 521 on the outer wall of the fixed roller 52. The conveyor belt 51 is slidably connected to the two fixed rollers 52. The inner wall of the conveyor belt 51 is provided with internal threads, and the threaded screw 54 is penetrated by the conveyor belt 51 and is threadedly connected to the inner wall of the conveyor belt 51. A first hand wheel 55 is fixedly connected to one end of the threaded screw 54 close to the conveyor belt 51. When the first hand wheel 55 is turned, the conveyor belt 51 slides along the length direction of the fixed roller 52.

[0043] In order to prevent other parts of the fixed roller 52 from scratching the upper packaging film conveyed to the heat sealing device 3, each fixed roller 52 is provided with a protective cover 53, and the conveyor belt 51 is arranged at one end of the protective cover 53. The length of the protective cover 53 is smaller than the length of the fixed roller 52, and the protective cover 53 is slidably connected to the fixed roller 52.

[0044] In order to limit the clamp chain, baffles 56 are fixedly connected to both sides of the conveyor belt 51. The height of the baffles 56 is higher than the surface of the conveyor belt 51. The clamp chain is transported to the heat sealing device 3 on the conveyor belt 51 between the baffles 56 on both sides.

[0045] like Figure 1 and Figure 3 As shown, both ends of the tensioning double rollers 6 are rotatably connected to the inner walls of the frame 1 on both sides, and the outer wall of one side of the frame 1 is rotatably connected to a second hand wheel 61. The tensioning double rollers 6 can be adjusted by rotating the second hand wheel 61.

[0046] The clip chain is released from the wire release drum 41 through the guide bucket 42, and the released clip chain passes through the wire release hole 431 on the sliding plate 43 and passes downward between the two reversing plates 44. After the two reversing plates 44 straighten the clip chain, the clip chain enters between the upper and lower packaging films. The guide roller and the tensioning double roller 6 guide and adjust the conveying of the clip chain. The clip chain passes through the conveyor belt 51 and enters the heat sealing device 3 together with the upper and lower packaging films for heat sealing. When the position of the clip chain needs to be adjusted, the first hand wheel 55 is turned, and the conveyor belt 51 slides along the fixed roller 52 to adjust the position of the clip chain when entering the heat sealing device 3. At the same time, the position of the sliding plate 43 is adjusted to make the wire release hole 431 and the position adapt to the position of the conveyor belt 51.

[0047] It is understandable that the components in the heat-sealing device 3 for heat-sealing the clip chain and the packaging film are prior art and will not be described in detail in this application.

[0048] The implementation principle of this embodiment is:

[0049] The installation of the packaging bag clamp chain is completed by extending the clamp chain between the upper and lower layers of packaging film and then heat-sealing them. When the position of the clamp chain needs to be adjusted, the first hand wheel 55 is turned, the screw rod 54 is rotated, and the conveyor belt 51 slides along the length direction of the fixed roller 52. The position of the sliding plate 43 is adjusted so that the position of the wire-releasing hole 431 adapts to the position of the conveyor belt 51. The clamp chain enters between the two layers of packaging film through the wire-releasing hole 431 and is transported to the conveyor belt 51 along a straight line. Finally, the clamp chain enters the heat-sealing device 3 at the same time as the two layers of packaging film in the length direction of the conveyor belt 51 relative to the length direction of the two layers of packaging film for heat sealing.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
