Abstract
Description
Technical Field
[0001] The utility model relates to bag making equipment, in particular to a cotton swab bag making machine used for producing cotton swab bags. Background Art
[0002] Cotton swab bags are used for sealed packaging of cotton swab products, and the bag opening is provided with a zipper that can be easily opened. If the cotton swab bags are produced by a plastic film bag-making machine, a double-layer film is generally used for discharging, and the double-layer film already has a zipper that is not interlocked with each other at the inner position of the bag opening. The above-mentioned production and bag-making process will have the following problems: when the double-layer film with the zipper is finally heat-sealed and cut into a single cotton swab bag body, since the upper and lower zippers of the double-layer film are not interlocked with each other, the upper and lower zippers will often be misaligned when subjected to the force of heat-sealing and cutting, resulting in various undesirable conditions such as skewness and cracks in the bag opening of the cotton swab bag body after heat-sealing and cutting, which seriously affects the subsequent cotton swab packaging quality. Summary of the invention
[0003] In view of the problems existing in the background technology, the purpose of the utility model is to provide a cotton swab bag making machine for producing cotton swab bags, which can ensure the production quality of the cotton swab bags.
[0004] The utility model is implemented through the following technical solutions:
[0005] The cotton swab bag making machine is characterized in that it includes a feeding component, the feeding component is used for feeding a double-layer film, the double-layer film has a clip chain that is not interlocked at the inner side of the bag opening, the double-layer film fed by the feeding component is pulled by a servo traction component after passing through a film material tensioning component, a film material left and right limiting components, and a clip chain point interlocking component, the servo traction component is electrically connected to a photoelectric switch, the photoelectric switch is used for tracking and detecting the color mark printed on the surface of the double-layer film, after the double-layer film is pulled out by the servo traction component, it is heat-sealed and cut into a single cotton swab bag body by a hot stamping knife component, a high-temperature resistant silicone conveyor belt is provided under the movable hot stamping knife of the hot stamping knife component, and the high-temperature resistant silicone conveyor belt is controlled by a servo motor for transmission.
[0006] The clip chain point fastening component comprises a point pressing head, and the point pressing head is pushed by a point pressing head cylinder to move up and down.
[0007] The left and right limiting components of the film material include an upper conveying roller and a lower conveying roller close to each other, and the upper conveying roller and the lower conveying roller are provided with V-shaped limiting grooves at positions corresponding to the passage of the double-layer film clamp chain.
[0008] A cooling component is arranged at the rear side of the hot ironing knife component. The cooling component comprises a cooling plate. The cooling plate is pushed up and down by a cooling plate cylinder.
[0009] The cotton swab bag making machine of the above technical solution can ensure the production quality of cotton swab bags. The key lies in that a clip chain point buckling component is provided before the hot ironing knife component. In this way, before the double-layer film with a clip chain is heat-sealed and cut into individual cotton swab bag bodies, the clip chain point buckling component first presses the upper and lower clip chains at the position to be cut to make the upper and lower clip chains at this position fully buckle. Then, when the subsequent hot ironing knife component heat-seals and cuts the double-layer film, since the cutting position is exactly at the position where the clip chain has been point-buckled, the upper and lower clip chains will not be misaligned when receiving the acting force of heat-sealing and cutting, ensuring that there are no quality problems at the bag mouth position of the cotton swab bag body, and thus ensuring the subsequent cotton swab packaging quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The present utility model has the following drawings:
[0011] Figure 1 is a schematic structural diagram of the present utility model,
[0012] Figure 2 is a conveying schematic diagram of the double-layer film in the working state. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0013] As shown in the figure, the cotton swab bag making machine of the present utility model includes a feeding component 1 for feeding the double-layer film A. The double-layer film A has unbuckled clip chains A1 on the inner side of the bag mouth. The double-layer film A fed by the feeding component 1 is tensioned by the film tensioning component 2, limited in the left and right positions by the film left and right limiting component, and then buckled at the clip chain points by the clip chain point buckling component, and then is pulled by the servo traction component 8. The servo traction component 8 is electrically connected to the photoelectric switch 5. The photoelectric switch 5 is used to track and detect the color marks printed on the surface of the double-layer film A to control the length of each film feeding of the servo traction component 8 and the accuracy of the subsequent heat-sealing and cutting positions. After the double-layer film A is pulled out by the servo traction component 8, it is heat-sealed and cut into individual cotton swab bag bodies B by the hot ironing knife component 9. A high-temperature resistant silica gel conveyor belt 11 is provided below the movable ironing knife of the hot ironing knife component 9, and the high-temperature resistant silica gel conveyor belt 11 is controlled by a servo motor for conveying. The clip chain point buckling component includes a point pressing head 7, and the point pressing head 7 is pushed up and down by a point pressing head cylinder 6; the film left and right limiting component includes an upper conveyor roller 3 and a lower conveyor roller 4 that are close to each other. The upper conveyor roller 3 and the lower conveyor roller 4 are provided with V-shaped limiting grooves at the positions corresponding to the passage of the double-layer film clip chain A1. The V-shaped limiting grooves limit the double-layer film in the left and right positions by limiting the clip chain during operation. A cooling component 10 is provided on the rear side of the hot ironing knife component 9. The cooling component includes a cooling plate, and the cooling plate is pushed up and down by a cooling plate cylinder.
[0014] The present utility model works as follows (see Figure 2)(Under the traction of the servo traction component 8, at the same time, the double-layer film A is unwound by the unwinding component 1. After unwinding, the double-layer film A reaches the chain clamp point fastening component for intermittent stay after being tensioned by the film tensioning component 2 and limited left and right by the left and right film limit components. At this time, the dot pressing head cylinder 6 pushes the dot pressing head 7 downward to dot press the upper and lower chain clamps at the position to be cut off so that the upper and lower chain clamps at this position are fastened (a fixedly installed dot pressing backing plate is provided below the dot pressing head). Next, at the hot stamping knife component 9, the movable stamping knife moves downward to thermally seal and cut the double-layer film A to form a single cotton swab bag body B. The movable stamping knife directly acts on the high-temperature resistant silica gel conveyor belt 11 (a fixedly installed supporting plate is provided at the bottom of the high-temperature resistant silica gel conveyor belt to support the conveyor belt). Then, the single cotton swab bag body B is intermittently conveyed on the high-temperature resistant silica gel conveyor belt 11 (the conveying speed is greater than the traction speed of the servo traction component 8, so that the cotton swab bag bodies B conveyed on the conveyor belt 11 can be separated from each other by a certain distance front and back). At the cooling component 10, the cooling plate cylinder pushes the cooling plate downward to cold press and flatten the cotton swab bag body B. Finally, the cotton swab bag body B intermittently conveyed on the high-temperature resistant silica gel conveyor belt 11 is clamped by the clamping manipulator and enters the next process of collection or packaging of cotton swab products.)
