Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a cotton towel packaging device. Background Technology

[0002] Cotton soft towels are non-woven fabrics made from fibers such as cotton, bamboo fiber, silk, and viscose, processed using non-woven techniques such as spunlace. They are then cut into various sizes and used as dry towels for daily cleaning and care by adults and infants. Because they are produced using advanced all-cotton spunlace non-woven fabric technology and then sterilized by high-pressure steam, they are soft, delicate, highly absorbent, and lint-free, making them a new environmentally friendly alternative to paper towels, cotton pads, and face towels. Cotton soft towels are manufactured using an assembly line method, with a heat-sealing device used at the end of the production line to seal them.

[0003] Chinese Patent Application No. 202421020199.X discloses a packaging device for processing cotton towels. Specifically, it discloses an operating table, a U-shaped frame fixedly installed on one side of the top of the operating table, a connecting plate fixedly installed on one side of the U-shaped frame, an electric push rod installed on the top of the connecting plate, a first pressure plate installed at the bottom of the electric push rod, a heating strip installed on one side of the first pressure plate, and second pressure plates installed on both the front and rear sides of the first pressure plate. A fixed platform is fixedly installed on the top of the operating table, a tray is movably installed inside the fixed platform, a sealing platform is fixedly installed on one side of the fixed platform, and limit rods are installed at the four corners of the bottom of the tray. The limit rods pass through the fixed platform and the operating table, and a first spring is sleeved on the outside of the limit rods. A pushing structure is installed on the top of the operating table. In use, the cotton towel is placed in the packaging bag and then on top of the tray. Activating the electric actuator moves the first pressure plate downwards, squeezing the cotton towel on top of the tray to expel air and prevent excessive air from entering the packaging bag. Simultaneously, the tray slides downwards under pressure, deforming the first spring on the outer side of the limiting rod. This deformed spring exerts a directional force on the tray, acting as a buffer to prevent excessive pressure and the packaging bag from bursting. As the first pressure plate moves downwards, the second pressure plates on both sides press against the top plate, causing the second support rod at the bottom of the top plate to slide inwards towards the first support rod, deforming the second spring. At the same time, a push plate on one side of the top plate pushes the clamping plates to move, thus clamping and aligning the cotton towel to prevent misalignment during sealing. However, this device has low packaging efficiency and cannot meet the requirements of assembly line production. Utility Model Content

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] The embodiment of this utility model is as follows:

[0020] refer to Figures 1 to 5 As shown, a cotton towel packaging device includes a frame, a packaging film unwinding mechanism 1, a traction mechanism 2, a deviation correction mechanism 3, a cotton towel conveying mechanism 4, a pushing mechanism 5, a negative pressure adsorption box 6, a folding mechanism 7, a first welding mechanism 8, a belt conveying mechanism 9, a second welding mechanism 10, and an output mechanism 11. The packaging film unwinding mechanism 1 is mounted on the frame and is used for unwinding and conveying the packaging film in roll form. The traction mechanism 2 is located at the output end of the packaging film unwinding mechanism 1, the deviation correction mechanism 3 is located at the output end of the traction mechanism 2, the negative pressure adsorption box 6 is located at the output end of the deviation correction mechanism 3, and the cotton towel conveying mechanism 4 is mounted on the frame and is used for unwinding and conveying the cotton towel. The output end of the feeding mechanism is located on the upper side of the negative pressure adsorption box 6, and is used to transport stacked soft towels. The pushing mechanism 5 is located on the upper side of the soft towel conveying mechanism 4, and is used to push the stacked soft towels on the soft towel conveying mechanism 4 into the negative pressure adsorption box 6. The folding mechanism 7 is located on the output end of the soft towel conveying mechanism 4 and is located on the upper side of the negative pressure adsorption box 6. The first welding mechanism 8 is located on the output end of the folding mechanism 7. The belt conveying mechanism 9 is located on the output end of the first welding mechanism 8. The second welding mechanism 10 is located on the output end of the belt conveying mechanism 9. The output mechanism 11 is located on the output end of the second welding mechanism 10.

[0021] This cotton towel packaging device forms a complete and efficient assembly line packaging system by rationally setting up various mechanisms on the frame. Specifically, the packaging film unwinding mechanism 1 unwinds and conveys the rolled packaging film, providing the basic material for subsequent packaging; the traction mechanism 2 and the correction mechanism 3 ensure accurate delivery of the packaging film and avoid deviation that affects packaging quality; the negative pressure adsorption box 6 can stably adsorb the packaging film, facilitating subsequent operations; the cotton towel conveying mechanism 4 conveys stacked cotton towels, and the pushing mechanism 5 accurately pushes them into the negative pressure adsorption box 6, achieving the initial bonding between the cotton towels and the packaging film; the folding mechanism 7 folds the packaging film, and the first welding mechanism 8 welds the center seal belt; the belt conveyor mechanism 9 conveys the cotton towel packaging film with the center seal belt welded to the second welding mechanism 10 for further welding, and finally the output mechanism 11 outputs the finished product. The various mechanisms of the entire device work together to greatly improve the packaging efficiency of cotton towels, meet the requirements of assembly line production, and effectively solve the problem of low packaging efficiency in existing cotton towel packaging devices.

[0022] Specifically, the folding mechanism 7 includes a guide groove plate 71 and a V-shaped guide plate 72. The guide groove plate 71 includes two inclined guide shoulders 711 and a center seam guide opening 712. The center seam guide opening 712 is located in the center of the top surface of the guide groove plate 711. The V-shaped guide plate 72 is located at the seam guide opening 712 between the two guide shoulders 711. It is used to gradually close the two sides of the packaging film to form a center seal. This structure is simple and effective, and can quickly and accurately complete the folding operation of the packaging film, improve the accuracy and efficiency of packaging, ensure the smooth progress of subsequent welding processes, and thus improve the quality and performance of the entire cotton towel packaging device.

[0023] Furthermore, the first welding mechanism 8 is located at the output end of the V-shaped guide plate 72 and on the upper side of the guide groove plate 71. The first welding mechanism 8 includes two welding rollers 81 and a drive motor 82 that drives the two welding rollers 81 to rotate through a gear assembly. This allows the welding operation to be performed immediately after the packaging film is folded to form the center seal, achieving a close connection between the folding and welding processes, reducing intermediate steps, and improving production efficiency. At the same time, the first welding mechanism 8, through the setting of the welding rollers 81, can perform uniform and stable welding on the center seal of the packaging film, ensuring welding quality, making the packaging film seal firm, and effectively preventing leakage problems of the cotton towel during subsequent transportation and use.

[0024] In this embodiment, the cotton towel conveying mechanism 4 includes a first belt conveyor assembly 41, a second belt conveyor assembly 42, and a third belt conveyor assembly 43. The second belt conveyor assembly 42 is distributed between the first belt conveyor assembly 41 and the third belt conveyor assembly 43. The first belt conveyor assembly 41 and the third belt conveyor assembly 43 are axially symmetrically distributed. The length of the first belt conveyor assembly 41 is greater than the length of the second conveyor assembly 42, resulting in a gap 44 at the output end of the second belt conveyor assembly 42. The pushing mechanism 5 is distributed above the gap. The stacked cotton towels span across the first belt conveyor assembly 41, the second belt conveyor assembly 42, and the third belt conveyor assembly 43, enabling stable conveying of the stacked cotton towels during the conveying process. When the stacked cotton towels reach the output end of the second belt conveyor assembly 42, the pushing mechanism 5 can conveniently and accurately push the stacked cotton towels into the negative pressure adsorption box, achieving stable conveying and precise pushing of the cotton towels. This improves the automation level and work efficiency of the entire packaging device and reduces errors and labor intensity caused by manual operation.

[0025] Furthermore, the second welding mechanism 10 includes an upper drive cylinder 101, an upper welding assembly 102 located at the lower end of the piston rod of the upper drive cylinder 101, a lower drive cylinder 103, and a lower welding assembly 104 located at the upper end of the piston rod of the lower drive cylinder 103. The upper welding assembly 102 includes a fixed seat 201 located on the piston rod of the upper drive cylinder 101, a cutter 202 located in the middle of the fixed seat 201, guide holes 203 located on the fixed seat 201 and distributed around the cutter 202, a guide rod 204 located in the guide hole 203, a spring 205 sleeved on the guide rod 204, a movable seat 206 located at the lower end of the guide rod 204, a through hole 207 on the movable seat 206 for the cutter 202 to pass through, and a welding block 208 located on the lower surface of the movable seat 206. This allows the upper welding assembly 102 to move downward when the upper drive cylinder 101 drives it. The guide rod 204 and spring 205 act as buffers and guides, ensuring that the cutter 202 and welding block 208 can act smoothly and accurately on the packaging film. At the same time, the lower drive cylinder 103 drives the lower welding assembly 104 to move upward, cooperating with the upper welding assembly 102 to weld the packaging film, further ensuring the sealing and firmness of the packaging. Moreover, the combined design of the cutter 202 and welding block 208 can cut the packaging film while welding, improving the integration and efficiency of the packaging process. The lower welding assembly 104 is equipped with an anvil 209 that cooperates with the cutter 202. When the cutter 202 in the upper welding assembly 102 moves downward to perform the cutting operation, the anvil 209 can provide a stable and flat cutting plane for the cutter, ensuring that the cutter 202 can accurately and cleanly cut the packaging film, avoiding problems such as uneven cutting and rough edges. Meanwhile, the presence of the cutting board can also protect other parts of the lower welding assembly 104 from direct impact from the cutter, extending the service life of the equipment. In conjunction with the cutter 202 and welding block 208 in the upper welding assembly 102, cutting and welding are carried out simultaneously, improving the quality and efficiency of packaging and making the entire cotton towel packaging device more perfect and reliable.
