Description

Technical Field

[0001] This utility model relates to the field of fabric packaging, and in particular to an automatic sealing fabric packaging machine. Background Technology

[0002] Fabric packaging machines mainly include fully automatic packaging machines, hydraulic balers, and vacuum packaging machines. They are suitable for packaging rolled fabrics, compressing loose materials, and sealing and moisture-proofing in the textile industry. After being rolled, the fabric does not need to be sorted and can enter the conveyor line in any direction. The servo motor drives the rollers to adjust the fabric roll posture to ensure accurate entry into the packaging station. The PE film is unfolded by the guide rollers and wraps the fabric roll. The three-sided sealing knife moves synchronously to complete the wrapping.

[0003] In existing fabric packaging machines, after packaging rolled fabric with PE film, when sealing both ends of the fabric, the PE film at both ends of the fabric is twisted together by the exhaust fan, resulting in multiple wrinkles at the ends of the PE film. The twisted PE film becomes thicker and more difficult to cut quickly. At the same time, the multiple wrinkles cause the PE films to stick together, and after the heat sealing knife is removed, the sealing position is not firmly adhered due to the tension of the film. Subsequently, during the heat sealing process on the thin wall of the fabric, the seals at both ends of the fabric may open. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sealing cloth packaging machine to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An automatic sealing fabric packaging machine includes a wrapping mechanism, a conveyor frame at the front of the wrapping mechanism, two symmetrically arranged closing mechanisms at the front of the conveyor frame, a material discharge conveying component at the middle of the conveyor frame, and two sealing mechanisms located on both sides of the rear end of the conveyor frame.

[0007] The sealing mechanism includes a sealing frame, with sealing cylinders at the top and bottom of the sealing frame. Sealing heat sealing knives are fixed to the telescopic parts of the two sealing cylinders. An air extraction pipe is fixed to one end of the sealing frame away from the sealing cylinders, and an air extraction fan is fixed to the other end of the air extraction pipe. Two sets of adsorption components for adsorbing the ends of the PE film are provided in the middle of the sealing frame.

[0008] Each adsorption assembly includes two film-supporting cylinders. Each film-supporting cylinder has a film-suction strip fixed to its telescopic part. A vacuum generator is fixedly installed at one end of each film-suction strip that extends out of the sealing frame. Each film-suction strip has a hollow structure, and a slot is opened on the side of each film-suction strip closest to the PE film.

[0009] Preferably, two sealing heat sealing knives are slidably connected inside the sealing frame, and the sealing frame is provided with grooves at the position of the suction strip.

[0010] Preferably, one end of the suction strip with the vacuum generator is slidably connected to the slot of the sealing frame, and the sealing frame has through holes at both ends that communicate with the vacuum pipe.

[0011] Preferably, the wrapping mechanism includes a frame, a film-cutting heat-sealing knife is provided on the front side of the frame, a stop bar is provided on the rear side of the film-cutting heat-sealing knife and fixed to the front side of the frame, three film-cutting cylinders are fixedly installed on the top of the film-cutting heat-sealing knife, the fixing parts of the three film-cutting cylinders are all fixed to the upper side of the frame, a fabric-pushing cylinder is fixedly installed on the rear side of the frame, and a fabric-pushing plate is fixed to the telescopic part of the fabric-pushing cylinder.

[0012] Preferably, the frame has a fabric inlet on the side for the fabric to enter, and a feeding conveyor is fixedly installed at the bottom of the frame corresponding to the fabric inlet. The top of the frame has a horizontal shaft for supporting the PE film roll, and the front of the frame has a pressure strip for fixing one end of the PE film.

[0013] Preferably, the closing mechanism includes a closing frame, a hot air blower inside the closing frame, a heating plate and a flattening cylinder on the rear side of the hot air blower, the heating plate being fixed to the telescopic part of the flattening cylinder, the flattening cylinder being fixed to the end of the closing frame away from the fabric, and a moving cylinder for pushing the closing frame to move being provided on the lower side of the closing frame.

[0014] Preferably, the sealing frame is provided with a push cylinder on its lower side for pushing it to move towards the end of the fabric.

[0015] The advantages compared to existing technologies are as follows:

[0016] The four film-supporting cylinders on the sealing frame push the four film-suction strips closer to the end of the PE film fitted onto the fabric blank. The vacuum generator creates suction at the groove of the film-suction strips to adhere the end of the PE film to the groove. Then, the four film-supporting cylinders move the four film-suction strips away from each other, thereby opening up the end of the PE film to prevent it from twisting together and creating too many wrinkles, thus preventing the PE film from being poorly sealed.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-10 As shown, an automatic sealing fabric packaging machine includes a wrapping mechanism 1, a conveyor frame 3 on the front side of the wrapping mechanism 1, two symmetrically arranged closing mechanisms 4 on the front side of the conveyor frame 3, a material discharge conveying component 6 in the middle of the conveyor frame 3, and two sealing mechanisms 2 located on both sides of the rear end of the conveyor frame 3.

[0033] In this embodiment: the sealing mechanism 2 includes a sealing frame 21, with sealing cylinders 22 at both the top and bottom of the sealing frame 21. Sealing heat-sealing knives 23 are fixed to the telescopic parts of both sealing cylinders 22. An exhaust pipe 24 is fixed to one end of the sealing frame 21 away from the sealing cylinders 22, and an exhaust fan 25 is fixed to the other end of the exhaust pipe 24. Two sets of adsorption components for adsorbing the ends of the PE film are located in the middle of the sealing frame 21. A push cylinder 29 is located on the lower side of the sealing frame 21 to push it towards the end of the fabric. Each set of adsorption components... The system includes two film-supporting cylinders 26, each with a film-suction strip 27 fixed to its telescopic section. A vacuum generator 28 is fixedly installed at one end of each film-suction strip 27 extending out of the sealing frame 21. Each film-suction strip 27 is hollow, and a slot is formed on the side of each film-suction strip 27 closest to the PE film. Two sealing heat-sealing knives 23 are slidably connected inside the sealing frame 21. The sealing frame 21 has grooves at the positions of the film-suction strips 27. The end of the film-suction strip 27 with the vacuum generator 28 is slidably connected within the slot of the sealing frame 21. The sealing frame 21 has through holes at both ends that connect to the suction pipe 24. The push cylinder 29 pushes the sealing frame 21 forward, while the suction fan 25 starts, drawing air out of the sealing frame 21 through the suction pipe 24. This creates suction near the through holes of the fabric, drawing the end of the tubular PE film covering the fabric into the sealing frame 21. During this process, the four film-supporting cylinders 26 on the sealing frame 21 extend and retract, pushing the suction strip 27 towards the end of the PE film inside the sealing frame 21. The vacuum generator 28 is used to evacuate air from the inside of the suction strip 27, thereby creating suction at the groove of the suction strip 27. The four suction strips 27 will adhere the ends of the PE film to the groove. Then, the four film-supporting cylinders 26 are extended to move the four suction strips 27 away from each other, thereby spreading the ends of the PE film to prevent them from twisting together and causing too many wrinkles. Then, the two sealing cylinders 22 are extended to push the corresponding sealing heat-sealing knife 23 to move, and the two sealing heat-sealing knives 23 push and cut the spread PE film to seal it.

[0034] In this embodiment: the wrapping mechanism 1 includes a frame 11. A film-cutting heat-sealing knife 14 is provided on the front side of the frame 11. A stop bar is provided on the rear side of the film-cutting heat-sealing knife 14 and fixed to the front side of the frame 11. Three film-cutting cylinders 15 are fixedly installed on the top of the film-cutting heat-sealing knife 14. The fixing parts of the three film-cutting cylinders 15 are all fixed to the upper side of the frame 11. A fabric-pushing cylinder 12 is fixedly installed on the rear side of the frame 11. A fabric-pushing plate 13 is fixedly installed on the telescopic part of the fabric-pushing cylinder 12. A fabric inlet is opened on the side of the frame 11 for the fabric to enter. A feeding conveyor assembly 5 is fixedly installed at the bottom of the frame 11 at the position corresponding to the fabric inlet. A horizontal shaft for supporting the PE film roll is provided on the top of the frame 11. A pressure strip for fixing one end of the PE film is provided on the front side of the frame 11. The fabric is fed into the frame 11 using the feeding conveyor 5. Then, the pusher plate 13 is pushed forward by the extension part of the pusher cylinder 12. At this time, the fabric pushes the vertical PE film forward to the rear end of the discharge conveyor 6. The PE film baffle on the upper side of the fabric prevents it from contacting the film cutting heat sealing knife 14. At the same time, the PE film on the upper side of the fabric is stretched to form a C-shaped structure and wrapped around the outside of the fabric. Then, the extension parts of the three film cutting cylinders 15 push the film cutting heat sealing knife 14 downward, thereby cutting the PE film wrapped around the outside of the fabric to form a cylindrical structure. The PE film not wrapped around the outside of the fabric will merge together to form a continuous PE film.

[0035] In this embodiment: the closing mechanism 4 includes a closing frame 42, inside which is a hot air blower 43. A heating plate 44 and a flattening cylinder 45 are provided on the rear side of the hot air blower 43. The heating plate 44 is fixed to the telescopic part of the flattening cylinder 45. The flattening cylinder 45 is fixed to the end of the closing frame 42 away from the fabric. A moving cylinder 41 is provided on the lower side of the closing frame 42 for pushing it to move. The moving cylinder 41 pushes the closing frame 42 to move towards the end of the fabric. The hot air blower 43 on the closing frame 42 heats the sealing of both ends of the fabric, thereby causing the PE film at both ends of the fabric to shrink and tighten. At the same time, when the fabric reaches the position of the heating plate 44, the flattening cylinder 45 pushes the heating plate 44 to move towards the end of the fabric, so that the heated plate 44 is attached to the sealing position of the PE film, making the sealing position of the PE film flat.

[0036] Working principle: During use, the feeding conveyor 5 conveys the fabric into the frame 11. Then, the pusher cylinder 12 pushes the pusher plate 13 to push the whole roll of fabric forward. At this time, the fabric pushes the vertical PE film forward to the rear end of the discharge conveyor 6. The pusher cylinder 12 drives the pusher plate 13 to the initial position. At this time, the PE film baffle on the upper side of the fabric prevents it from contacting the film cutting heat sealing knife 14. At the same time, the PE film on the upper side of the fabric is stretched to form a C-shaped structure and wraps around the outside of the fabric. Then, the three film cutting cylinders 15 push the film cutting heat sealing knife 14 downward, thereby cutting the PE film wrapped around the outside of the fabric to form a cylindrical structure. The PE film not wrapped around the outside of the fabric will merge together to form a continuous PE film, which facilitates the subsequent film wrapping operation of the fabric.

[0037] Then, the top-push cylinder 29 pushes the sealing frame 21 forward, while the exhaust fan 25 starts to draw air out of the sealing frame 21 through the exhaust pipe 24. This creates suction near the through-hole of the fabric, drawing the end of the tubular PE film covering the fabric into the sealing frame 21. During this process, the four film-supporting cylinders 26 on the sealing frame 21 push the suction strips 27 towards the end of the PE film inside the sealing frame 21. Simultaneously, the vacuum generator 28 evacuates air from the suction strips 27, creating suction at the grooves of the suction strips 27. The four suction strips 27 then adhere the end of the PE film to the grooves. The four film-supporting cylinders 26 then move the four suction strips 27 away from each other, thus spreading the end of the PE film to prevent it from twisting together and creating excessive wrinkles. Finally, the two sealing cylinders 22 push the film... The corresponding sealing heat-sealing knife 23 moves, and the two sealing heat-sealing knives 23 push and cut the stretched PE film to seal it. Then, the extension part of the pushing cylinder 29 drives the sealing frame 21 away from the end of the fabric. At this time, the fabric covered with PE film is conveyed forward by the material conveying component 6. When the fabric moves to the heating plate 44, the leveling cylinder 45 pushes the heating plate 44 to move towards the end of the fabric, so that the heated heating plate 44 is attached to the sealing position of the PE film, making the sealing position of the PE film flat. Then, the material conveying component 6 continues to convey, and the moving cylinder 41 pushes the closing frame 42 to move towards the end of the fabric. The hot air fan 43 on the closing frame 42 heats the sealing at both ends of the fabric, so that the PE film at both ends of the fabric shrinks and tightens. Then the fabric can be sent into the heat shrink machine to completely tighten the PE film on the outside of the fabric, thereby completing the packaging operation of the fabric.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
