Description

Technical Field

[0001] The utility model belongs to the technical field of packaging paperboard processing, and in particular relates to a packaging paperboard laminating device. Background Art

[0002] Packaging cardboard is a kind of cardboard material such as corrugated cardboard. In the industry, packaging cardboard is processed into various products used for packaging items, such as packaging boxes. Packaging cardboard has the advantages of convenience, low production cost, recyclable materials, and easy degradation in the natural environment. Therefore, it has very high environmental and economic value.

[0003] During the production process, packaging paperboard is made of paper material, so its waterproof properties are not particularly high. For products with high requirements for water release, a protective film is often needed on the packaging paperboard to improve its waterproofness and sealing. Currently, lamination is done through a professional lamination production line in the workshop. On the production line, the packaging paper is transferred to the lamination station through a conveyor belt and then laminated using lamination equipment.

[0004] However, in the actual production process, when special customized packaging cardboard (characterized by low production volume), especially long cardboard, the length of the film unrolled from the laminating roll is very long during the laminating process. The accompanying technical problem is that in order to fully fit the film material to the cardboard, it is necessary to unroll the film while comparing the film material with the cardboard for reference, and fully fit it to the cardboard. However, the unrolled film is long, and the soft film is easy to be folded downward, and it is difficult to correct. When pulling the film, the film is adjusted from the folded state to the tensioned state. Due to poor control of the force, it is easy to cause the film to break at the pulling position. After breaking, the unrolled length of the film is damaged and can only be scrapped, and the unrolled length is relatively large. Therefore, in the production process, when laminating such a long cardboard, a lot of film is scrapped.

[0005] This not only causes economic losses, but also increases the difficulty of laminating. Therefore, when laminating such long cardboard, how to correct the collapse of the long unwinding film and laminate it on the cardboard in a more fitting posture has become a current technical problem.

[0006] Based on the above background, the purpose of the utility model is to provide a packaging paperboard laminating device.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A packaging paperboard film coating device comprises a film coating unwinding mechanism, wherein the film coating unwinding mechanism is slidably assembled on a track;

[0009] The packaging paperboard film coating device also includes a pulling mechanism for pulling the film coating unwinding mechanism;

[0010] The pulling mechanism comprises a pulling motor, the pulling motor is equipped with a belt reel, a pulling belt is wound on the belt reel, and the pulling end of the pulling belt is installed on the film unwinding mechanism;

[0013] A long return spring is sleeved on the long slide rod, and two ends of the long return spring are fixedly connected to the slide seat and the track respectively;

[0014] During the laminating process, the pulling motor drives the take-up wheel to pull the laminating unwinding mechanism to slide on the track. After sliding and adjustment, the unrolled film is stretched straight over a long distance and adhered to the longer cardboard.

[0015] Preferably, the film coating unwinding mechanism comprises a film coating frame arranged at intervals in front and behind;

[0016] An upper laminating roller and a lower laminating roller are rotatably connected between the laminating frames, and laminating motors for driving the upper laminating roller and the lower laminating roller to rotate are respectively mounted on the laminating frames.

[0042] Example 1

[0043] like Figure 1-5 As shown, a packaging paperboard laminating device includes a laminating unwinding mechanism 2, and the laminating unwinding mechanism 2 is slidably assembled on a track 1; specifically, a track 1 is respectively adapted on the front and rear sides of the laminating unwinding mechanism 2.

[0044] The above-mentioned packaging cardboard laminating device also includes a pulling mechanism 3 for pulling the laminating unwinding mechanism 2; when laminating the long packaging cardboard, the laminating unwinding mechanism 2 is pulled and moved to straighten the long unwinding film (for this type of product, during the production process, the length of the cardboard often varies greatly according to the customer's customized requirements. During the laminating process, the operation can only be performed while unwinding the film and comparing the cardboard lengths).

[0045] Specifically, the pulling mechanism 3 includes a pulling motor 31 , and a take-up wheel is mounted on the pulling motor 31 . A pulling belt is wound on the take-up wheel, and a pulling end of the pulling belt is mounted on the film unwinding mechanism 2 .

[0046] Specifically, the above-mentioned film unwinding mechanism 2 includes a film frame 21 arranged at intervals in front and back; according to the existing method, the film frame 21 is rotatably connected with an upper film roller 22 and a lower film roller 23 (the film on the packaging paperboard is often a double-layer film to ensure high waterproof properties), and according to the existing film unwinding method of the film laminating machine, the film frame 21 is respectively equipped with a film motor 24 that drives the upper film roller and the lower film roller to rotate (the film motor 24 is fixedly connected with a mounting plate, and the mounting plate is fastened to the film frame 21 by a fastening screw). The specific method is: the output shaft of the film motor 24 is connected to the rotating shaft installed on the upper film roller and the lower film roller through a coupling.

[0047] The left and right side walls of the laminating frame 21 are respectively fixedly connected with assembly rods 25, and the assembly rods 25 are fixedly connected to the top of the slide 26 (the bottom of the laminating unwinding mechanism 2 is fixedly connected with the slide 26 slidably connected to the long slide rod).

[0048] During the laminating process, the pulling motor 31 drives the belt reel 311 to pull the laminating unwinding mechanism 2 to slide on the track 1. After sliding and adjustment, the unrolled film is straightened over a long distance and attached to the cardboard with a large length. The specific method is: a long pulling screw 32 is fixedly connected to the assembly rod 25, a pull ring body is fixedly connected to the long pulling screw 32, a buckle is fixedly connected to the pull belt, and the buckle is hung on the pull ring body 33.

[0049] During the working process, the pulling motors 31 on both sides are turned on synchronously. At this time, the pulling motor 31 drives the winding wheel 311 to wind. At this time, under the pulling of the pull belt, the entire coating unwinding mechanism 2 is pulled to the right. At the same time, the unwound film gradually changes from a bagged state to a straightened state. When it reaches the appropriate pulling position, the pulling is stopped, and the operator presses the unwound film (the film has a certain tension at this time) down onto the cardboard.

[0050] After the stretching process, the film is not only relatively straight but also has a high flatness. Therefore, it can be laminated on the cardboard in a more precise manner compared with the cardboard. The film is then cut and sent to the subsequent hot pressing equipment to form a laminated product after hot pressing.

[0051] In the production process, for large cardboards of different lengths, it is only necessary to control the pulling displacement of the laminating unwinding mechanism 2 through the pulling motor 31 to meet the processing needs of multiple sizes.

[0052] The above method not only greatly reduces the difficulty of laminating large-size products, but also has high flexibility. It can flexibly adjust, pull and unwind the film according to production and processing needs, greatly improving production and processing efficiency.

[0053] Example 2

[0054] like Figure 1-5 As shown, based on the structure of Example 1, this embodiment is provided with a slide groove body slidably connected to the slide seat 26 on the track 1; the slide seat 26 is limitedly slidable in the slide groove body.

[0055] The specific sliding mode adopts limited sliding. Specifically, the slide seat 26 includes a main sliding part, and the limited sliding part is integrally formed on the front and rear side walls of the main sliding part. Correspondingly, the slide groove body includes a main groove part slidably connected to the main sliding part, and the two sides of the main groove part are integrally formed with limited groove parts of the limited sliding part, and the limited sliding part slides in the limited groove part.

[0056] Example 3

[0057] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, the packaging paperboard laminating device further includes a reset mechanism. When the pulling motor 31 pulls the laminating unwinding mechanism 2 and the film unwinding is completed, the laminating unwinding mechanism 2 is reset.

[0058] Specifically, the reset mechanism includes a long slide rod 41 fixedly assembled in the track 1; a long reset spring 42 is sleeved on the long slide rod 41, and the two ends of the long reset spring 42 are respectively fixedly connected to the slide seat 26 and the track 1 (specifically: the two ends of the long slide rod 41 are respectively fixedly connected to the groove walls on both sides of the main groove).

[0059] During the working process, when the pulling motor 31 (according to the existing conventional method, the pulling motor 31 is fixed on the motor seat) uses the pull belt to pull, at this time, the slide seat 26 slides relative to the long slide rod 41, and the long reset spring 42 is elastically stretched. When the lamination is completed, the pulling motor 31 reversely drives the tape wheel 311 to unwind the tape. At this time, under the elastic restoring force of the long reset spring 42, the lamination unwinding mechanism 2 is reset, ready to coat the next product again.

[0060] Example 4

[0061] like Figure 1-5 As shown, based on the structure of Example 1, this embodiment is welded with a plurality of mounting feet 11 (with mounting holes on the mounting feet 11) on the front and rear side walls of the track 1 in accordance with the existing conventional manner; the mounting feet 11 are fixedly assembled on the frame of the conveyor.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
