Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and specifically to a film feeding device for a packaging machine. Background Technology

[0002] Packaging machines are mainly used to package products, protecting them and enhancing their appearance. They are widely used in the filling, sealing, and coding processes of bagged and bottled products in industries such as food, pharmaceuticals, daily chemicals, hardware, lighting, and furniture.

[0003] In existing film feeding devices used in packaging machines, the rotation speeds of the front and rear tension rollers may differ during operation. This can lead to excessive or insufficient film tension, resulting in wrinkles or tears, affecting packaging quality. Furthermore, dust can accumulate on the surface of the tension rollers over time, reducing friction between the rollers and the film and hindering conveying. Therefore, we propose a film feeding device for packaging machines to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a film feeding device for packaging machines, in order to solve the problem mentioned in the background art that the rotation speeds of the front and rear tension rollers may differ during operation. This can lead to excessive or insufficient film tension, resulting in wrinkles or tears, which affects the packaging effect. Furthermore, the surface of the tension rollers may accumulate dust over time, which reduces the friction between the tension rollers and the film, affecting the conveying process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A film feeding device for a packaging machine includes a worktable, a fixed seat fixedly connected to the upper surface of the worktable, a waste storage component provided on the lower surface of the worktable, a movable seat provided inside the fixed seat, a lifting motor fixedly connected to the top of the fixed seat, a fan provided on the top of the waste storage component, a tension roller component provided inside the movable seat, a waste suction hose fixedly connected to the top of the fan, and a dust scraper provided at the bottom of the tension roller component.

[0007] The dust scraping component includes a dust suction head, and a dust scraping strip is fixedly connected to the top of the dust suction head.

[0008] Furthermore, two waist-shaped grooves are symmetrically arranged on both sides of the fixed base.

[0009] Furthermore, the movable seat includes a mounting base, with two limiting pins symmetrically fixedly connected to both ends of the mounting base. The two limiting pins are slidably connected to two waist-shaped grooves, and the output end of the lifting motor passes through the fixed base and is threadedly connected to the top of the mounting base.

[0010] Furthermore, the tension roller component includes a tension roller, one end of which passes through the mounting base and is fixedly connected to a roller motor. Both ends of the tension roller are rotatably connected to the inner ends of the mounting base, the roller motor is fixedly connected to the mounting base, the bottom of the dust suction head is fixedly connected to the mounting base, and the top of the dust scraper is tightly fitted to the tension roller.

[0011] Furthermore, the other end of the waste suction hose passes through the fixing seat and is fixedly connected to the dust suction head.

[0012] Furthermore, the waste storage component includes a negative pressure box, inside which a waste storage box is movably connected, and the top of the negative pressure box is fixedly connected to a fan.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a lifting motor to move the movable seat. Through two limiting pins on both sides of the mounting seat, it slides inside the waist-shaped groove on the fixed seat, which can drive the tension roller component to move, thereby adjusting the film tension and avoiding problems such as wrinkles or tears caused by excessive or insufficient tension, which would affect the packaging effect.

[0015] 2. This utility model uses a dust scraper strip that adheres to the bottom of the tension roller to scrape off the dust on the tension roller. Then, a fan sucks the dust that falls into the dust collection head into the waste storage component for centralized collection, thus avoiding secondary pollution. Attached Figure Description

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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a film feeding device for a packaging machine, including a workbench 1, a fixed seat 2 fixedly connected to the upper surface of the workbench 1, a waste storage component 3 provided on the lower surface of the workbench 1, a movable seat 4 provided inside the fixed seat 2, a lifting motor 5 fixedly connected to the top of the fixed seat 2, a fan 6 provided on the top of the waste storage component 3, a tension roller component 7 provided inside the movable seat 4, a waste suction hose 8 fixedly connected to the top of the fan 6, and a dust scraper component 9 provided at the bottom of the tension roller component 7;

[0023] The dust scraping component 9 includes a dust suction head 901, and a dust scraping strip 902 is fixedly connected to the top of the dust suction head 901.

[0024] Two waist-shaped grooves 201 are symmetrically arranged on both sides of the fixed base 2.

[0025] The movable seat 4 includes a mounting base 401. Two limiting pins 402 are symmetrically fixed to both ends of the mounting base 401. The two limiting pins 402 are slidably connected to two oblong grooves 201. The output end of the lifting motor 5 passes through the fixed base 2 and is threadedly connected to the top of the mounting base 401. In this example, the oblong grooves 201 facilitate smooth sliding of the limiting pins 402 at both ends of the mounting base 401 within the oblong grooves 201.

[0026] The tension roller assembly 7 includes a tension roller 701. One end of the tension roller 701 passes through the mounting base 401 and is fixedly connected to a roller motor 702. Both ends of the tension roller 701 are rotatably connected to the inner ends of the mounting base 401. The roller motor 702 is fixedly connected to the mounting base 401. The bottom of the dust suction head 901 is fixedly connected to the mounting base 401. The top of the dust scraper 902 is tightly fitted to the tension roller 701.

[0027] The other end of the waste suction hose 8 passes through the fixed base 2 and is fixedly connected to the vacuum head 901.

[0028] The waste storage component 3 includes a negative pressure box 301, and a waste storage box 302 is movably connected inside the negative pressure box 301. The top of the negative pressure box 301 is fixedly connected to the fan 6. In this example, by setting up the waste storage box 302, it is convenient to collect the dust scraped off by the dust scraping component 9, and avoid re-contamination of the tension roller 701.

[0029] Working principle: The roller motor 702 drives the tension roller 710 to rotate, thereby feeding the film to the packaging machine. The lifting motor 5 drives the two limit pins 402 on both sides of the mounting base 401 to slide inside the two waist-shaped grooves 201, thereby driving the tension roller component 7 to rise and fall, adjusting the film tension. During this process, the dust scraper 902 contacts the bottom of the tension roller 701 and scrapes off the dust on the tension roller 701. The fan 6 sucks the dust inside the dust suction head 901 into the waste storage box 302 inside the negative pressure box 301 through the waste suction hose 8.
