Description

Technical Field

[0001] This utility model relates to the field of roll film splicing technology, specifically a roll film splicing mechanism. Background Technology

[0002] Strip packaging machines are machines used for packaging processing. They continuously feed film in rolls. After each roll of film is used up, workers need to replace it with a new roll.

[0003] Traditional strip packaging machines require manual film replacement when changing packaging film rolls. Each replacement takes about 5-10 minutes, affecting production efficiency and equipment uptime. Color marks may not align properly when the packaging machine attaches the film, often resulting in a dozen or so packages with misaligned color marks, leading to material waste, wasted manpower, and reduced work efficiency.

[0004] Furthermore, in many film splicing devices in the packaging industry, there is an overlap between the old and new film rolls during splicing. The thickness of the overlapped portion exceeds the gap of the bag forming mechanism of the packaging machine. When the overlapped film passes through this gap, it gets stuck at this station. When the film continues to be pulled, it will cause the film to break at the bag forming mechanism. In addition, there are film splicing mechanisms on the market, but the entire splicing process requires a long downtime to complete. Moreover, the adhesion between the tape and the film rolls on both sides of the splice is not high. It is easy for the old and new film to break due to the tape not being firmly adhered, which will greatly affect production efficiency and equipment operating efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a roll film splicing mechanism to solve the above problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0007] A roll film splicing mechanism includes a splicing side panel, a manual cutting station, an automatic cutting station, and a tape application station, wherein the manual cutting station, the automatic cutting station, and the tape application station are all connected to the splicing side panel.

[0008] The automatic cutting station includes an automatic cutting A adsorption component, an automatic cutting B adsorption component, an automatic cutting assembly, and a rolling device. The automatic cutting A adsorption component and the automatic cutting B adsorption component are interleaved and spliced ​​together. The automatic cutting assembly is located on one side of both the automatic cutting A adsorption component and the automatic cutting B adsorption component, corresponding to the gap between them. The rolling device is located on the opposite side of the automatic cutting assembly and elastically fits the surfaces of both the automatic cutting A adsorption component and the automatic cutting B adsorption component. This eliminates the previous method of overlapping old and new rolls of film. Instead, the manual cutting station and the automatic cutting station work together to use a two-sided aligned splicing method, avoiding roll breakage when the station is stuck or when the film continues to be pulled. Furthermore, the entire splicing process does not require long machine downtime to complete. The adhesion between the tape and the rolls of film on both sides of the splice is further improved by the rolling device, preventing the old and new rolls of film from breaking due to the tape not being firmly adhered. This improves production efficiency and equipment operating efficiency.

[0009] Preferably, the manual cutting station includes a manual cutting telescopic device, a manual cutting A adsorption component, and a manual cutting B adsorption component. The manual cutting telescopic device is connected to the splicing side plate, and the telescopic end of the manual cutting telescopic device is connected to the manual cutting B adsorption component. The manual cutting A adsorption component is fixed to the splicing side plate, and a gap is left between the manual cutting A adsorption component and the manual cutting B adsorption component.

[0013] Preferably, the automatic cutting sliding device is a rodless cylinder.

[0014] Preferably, the rolling device includes a roller shaft, a rolling plate, and a rolling telescopic device. The two ends of the roller shaft are elastically connected to the rolling plate, the rolling plate is connected to the telescopic end of the rolling telescopic device, and the rolling telescopic device is fixed on the automatic cutting A adsorption component and the automatic cutting B adsorption component.

[0015] Preferably, both the automatically cutting A adsorption component and the automatically cutting B adsorption component have lever cylinders embedded inside.

[0016] Preferably, all six of the following are equipped with vacuum suction cups: manual cutting of adsorbent A, manual cutting of adsorbent B, automatic cutting of adsorbent A, automatic cutting of adsorbent B, and tape application station.

[0017] Preferably, a tape-applying rotating device is provided on one side of the tape-applying station. The tape-applying rotating device is connected to the splicing side plate and drives the tape-applying station to rotate.

[0018] Compared to existing technologies, this utility model discloses a film splicing mechanism, including a splicing side plate, a manual cutting station, an automatic cutting station, and a tape-applying station. These four components work together to eliminate the previous method of overlapping old and new film rolls. Instead, the manual and automatic cutting stations work together to align the two sides of the film, preventing the film from breaking when stuck at the station or during continued film pulling. Furthermore, the entire splicing process does not require long machine downtime. The adhesion between the tape and the film rolls on both sides of the splice is further improved by a rolling device, preventing the old and new film rolls from breaking due to insufficient tape adhesion. This improves production efficiency and equipment operating efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] A roll film splicing mechanism includes a splicing side plate 1, a manual cutting station 2, an automatic cutting station 3, and a tape application station 4, wherein the manual cutting station 2, the automatic cutting station 3, and the tape application station 4 are all connected to the splicing side plate 1.

[0030] The automatic cutting station 3 includes an automatic cutting A adsorption component 31, an automatic cutting B adsorption component 32, an automatic cutting assembly 33, and a rolling device 34. The automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32 are spliced ​​together with gaps. The automatic cutting assembly 33 is located on one side of the automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32, and corresponds to the gap between the two. The rolling device 34 is located on the opposite side of the automatic cutting assembly 33 and elastically fits the surfaces of the automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32.

[0031] The manual cutting station 2 includes a manual cutting telescopic device 21, a manual cutting A adsorption component 22, and a manual cutting B adsorption component 23. The manual cutting telescopic device 21 is connected to the splicing side plate 1, and the telescopic end of the manual cutting telescopic device 21 is connected to the manual cutting B adsorption component 23. The manual cutting A adsorption component 22 is fixed on the splicing side plate 1, and a gap is left between the manual cutting A adsorption component 22 and the manual cutting B adsorption component 23.

[0032] The telescopic end of the manual cutting telescopic device 21 is also provided with a manual cutting rotating device 211 at the connection between the telescopic end and the manual cutting B adsorption component 23, and the manual cutting rotating device 211 drives the manual cutting B adsorption component 23 to rotate.

[0033] The automatic cutting assembly 33 includes an automatic cutting telescopic device 331, an automatic cutting sliding device 332, and an automatic cutting blade 333. The automatic cutting telescopic device 331 is fixed on the automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32, and the telescopic end of the automatic cutting telescopic device 331 is connected to the automatic cutting sliding device 332. The automatic cutting blade 333 is movably connected to the automatic cutting sliding device 332.

[0034] The cutting end of the automatic cutting tool 333 corresponds to the gap between the automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32.

[0035] The automatic cutting sliding device 332 is a rodless cylinder.

[0036] The rolling device 34 includes a roller shaft 341, a rolling plate 342, and a rolling telescopic device 343. The roller shaft 341 is elastically connected to the rolling plate 342 at both ends. The rolling plate 342 is connected to the telescopic end of the rolling telescopic device 343. The rolling telescopic device 343 is fixed on the automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32. Protrusions are provided on the surfaces of the automatic cutting A adsorption component 31 corresponding to both ends of the roller shaft 341. The purpose of elastically connecting the roller shaft 341 to the rolling plate 342 is to not affect the normal operation of the roll film. When the rolling telescopic device 343 is contracted, the roller shaft 341 contacts the protrusions, thereby increasing the distance between the roller shaft 341 and the surfaces of the automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32. Conversely, when rolling up and down, the elasticity improves the adhesion between the tape and the roll film. The elastic connection method includes, but is not limited to, springs.

[0037] The automatic cutting A adsorption component 31 and the automatic cutting B adsorption component 32 are each internally equipped with a lever cylinder 300.

[0038] Vacuum suction cups are provided on all six of the following: the manual cutting A adsorption component 22, the manual cutting B adsorption component 23, the automatic cutting A adsorption component 31, the automatic cutting B adsorption component 32, and the tape application station 4.

[0039] The tape-applying station 4 is provided with a tape-applying rotating device 41 on one side. The tape-applying rotating device 41 is connected to the splicing side plate 1 and drives the tape-applying station 4 to rotate.

[0040] Working Mode: During normal operation, the film roll passes from bottom to top through the automatic cutting A suction unit 31 and the automatic cutting B suction unit 32 to the upper work line. At this time, the vacuum suction cups of the automatic cutting A suction unit 31 and the automatic cutting B suction unit 32 are not working. When the film roll is almost used up, the operator manually winds one end of the new film roll from bottom to top and places it on the manual cutting A suction unit 22 and the manual cutting B suction unit 23. At this time, the vacuum suction cups of the manual cutting A suction unit 22 and the manual cutting B suction unit 23 generate suction to hold the new film roll. The operator uses a cutting knife to cut the end of the new film roll using the gap between the manual cutting A suction unit 22 and the manual cutting B suction unit 23. The cut end of the new roll film is aligned with the side of the manual cutting suction unit 23 (B). Simultaneously, the vacuum suction cups of both the automatic cutting suction unit 31 (A) and the automatic cutting suction unit 32 (B) begin to hold the used old roll film in place. The lever cylinder 300 extends to press the side of the old roll film, assisting in the process. The automatic cutting telescopic device 331 retracts, and the automatic cutting sliding device 332 drives the automatic cutting cutter 333 to move horizontally and cut the old roll film, ensuring the cut end aligns with the side of the automatic cutting suction unit 31 (A). After cutting, the automatic cutting assembly 33 resets, the lever cylinder 300 retracts completely, the vacuum suction cup of the automatic cutting suction unit 32 (B) stops adsorbing, and the old roll film falls below.

[0041] Next, the manual cutting telescopic device 21 retracts, and the manual cutting rotating device 211 rotates synchronously, aligning the manual cutting B adsorption component 23 with the automatic cutting B adsorption component 32. The vacuum suction cup of the manual cutting B adsorption component 23 stops adsorption, and the manual cutting B adsorption component 23 resets. The vacuum suction cup of the automatic cutting B adsorption component 32 then begins adsorption to complete the alternation of new roll film.

[0042] Tape is placed in advance at tape application station 4, and the vacuum suction cups at tape application station 4 adsorb the adhesive side of the tape. Tape application rotating device 41 rotates, so that the tape on tape application station 4 is adhered to the gap between automatic cutting A suction component 31 and automatic cutting B suction component 32, that is, the junction of old roll film and new roll film. Rolling telescopic device 343 drives roller 341 on roller plate 342 to roll back and forth against the current roll film surface and tape surface, so that the tape is fully adhered and then resets. Then the vacuum suction cups on automatic cutting A suction component 31 and automatic cutting B suction component 32 stop adsorbing, and the spliced ​​roll film works normally.
