Description

Technical Field

[0001] This invention relates to a disposable foot bath bag production device, belonging to the field of foot bath bag production technology. Background Technology

[0002] During the production process, the air inlet tube on the foot bath bag needs to be placed manually and installed on the foot bath bag using a roller-type rolling and hot-pressing method. This production method results in relatively low production efficiency for foot bath bags. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a disposable foot bath bag production device, which solves the problem of low production efficiency caused by the need for manual placement of the tube and the use of roller rolling in the original foot bath bag production process with air inlet tube.

[0004] The technical problem to be solved by this invention is achieved by the following technical solution:

[0005] A disposable foot bath bag production device includes a material rack, a material processing component, a heat sealing component, an elastic band heat sealing component, and a segmented cutting component arranged sequentially from front to back. The material rack includes an upper roller and an lower roller, both with a film wound on them. The film on the upper and lower rollers is drawn to the heat sealing component and heat-sealed. The material processing component is located between the material rack and the heat sealing component, and from top to bottom includes an upper punching component and a lower air inlet pipe component. The film on the upper roller is drawn through the upper punching component, which includes a first base plate and a first pusher. The output end of the first pusher faces downwards and towards the top surface of the first base plate. The film drawn from the upper roller passes through the top surface of the first base plate. Several punches are fixedly connected to the bottom surface of the output end of the first pusher. The lower air inlet pipe component includes a material hopper, a slide rail, and a fixing frame. The second pusher and the fixed mold are as follows: a discharge pipe is provided at the bottom of the hopper; a slide rail is located below the hopper; a first slider is slidably mounted on the slide rail; a robotic arm is mounted on the first slider; a fixed frame is located on one side of the film pulled out from the feed roller; a fixed mold is mounted on the side wall of the fixed frame; the bottom end of the fixed mold is directly above the film pulled out from the feed roller; the robotic arm passes sequentially through the bottom outlet of the discharge pipe and the fixed mold during the movement of the first slider; the second pusher is fixedly installed below the fixed mold and the film pulled out from the feed roller; the output end of the second pusher faces upward; a high-temperature cloth is placed between the second pusher and the film pulled out from the feed roller; an upper groove is formed on the bottom end of the positioning film; an ironing head is fixedly connected to the top end of the output end of the second pusher; a lower groove is formed on the top end of the ironing head; the upper groove and the lower groove are pressed together after being raised by the second pusher.

[0006] As a preferred embodiment, a crossbeam is fixedly installed between the discharge pipe and the slide rail. A connecting rod is rotatably sleeved on the crossbeam. A notch is opened on the side wall at the bottom outlet of the hopper. A push rod is hinged to the top of the connecting rod. The end of the push rod away from the connecting rod extends through the notch into the bottom of the inner cavity of the hopper. A second slider is fixedly connected to the end of the push rod located in the inner cavity of the hopper. The cross-sectional diameter of the second slider is larger than the notch. The second slider collides with the pipe material stored in the hopper.

[0007] As a preferred embodiment, a spring is hinged at the bottom outlet of the discharge pipe, one end face of the spring is pressed by a spring structure, and the other end face of the spring is matched and pressed against the bottom outlet of the discharge pipe.

[0008] As a preferred embodiment, a printing component is also fixedly installed between the feeding roller and the feeding punching assembly, and the printing component is a pad printing machine.

[0009] The beneficial effects of this invention are as follows: The foot bath bag production device mentioned in this invention provides a robotic arm capable of placing the tube, realizing automated transportation of the air inlet pipe, thereby achieving the complete automated production of the foot bath bag. The material processing component punches holes in the upper layer of the double-layer film and heat-presses the air inlet pipe onto the lower layer of the film. After the upper and lower layers of film are heat-pressed together, a composite film is formed. During the heat-pressing process, a certain area needs to be left unpressed. The unpressed area becomes the inner cavity passage of the composite film. The air inlet pipe is located at one end of this passage. It is formed in one step by high-temperature heat pressing, which is different from roller rolling and manual placement of the tube, thus improving production efficiency. Attached Figure Description

[0014] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0015] like Figure 1-3As shown, a disposable foot bath bag production device includes a material rack, a material processing component, a heat sealing component, an elastic band heat sealing component, and a segmented cutting component arranged sequentially from front to back. The material rack includes an upper feeding roller 1 and an lower feeding roller 2, both of which have film wound on them. The film on the upper feeding roller 1 and the lower feeding roller 2 is pulled to contact the heat sealing component and is heat sealed. The material processing component is located between the material rack and the heat sealing component, and from top to bottom includes an upper feeding punching component and a lower feeding air inlet pipe component. The upper feeding roller 1 has... The film is pulled through the feeding and punching assembly, which includes a first base plate and a first pusher 3. The output end of the first pusher 3 faces downward and towards the top surface of the first base plate. The film pulled from the feeding roller 1 passes through the top surface of the first base plate. Several punches are fixedly connected to the bottom surface of the output end of the first pusher 3 (each pusher in the text can be a cylinder). The unloading and air inlet assembly includes: a hopper 4, a slide rail 5, a fixing frame 6, a second pusher 7, and a fixing mold 11. A discharge pipe 9 is provided at the bottom of the hopper 4. The slide rail 5 is located below the hopper 4. A first slider 10 is slidably mounted on the slide rail 5, and a robotic arm is mounted on the first slider 10. The fixed frame 6 is located on one side of the film pulled out from the feed roller 2. A fixed mold 11 is mounted on the side wall of the fixed frame 6, and the bottom end of the fixed mold 11 is directly above the film pulled out from the feed roller 2. During the movement of the first slider 10, the robotic arm passes sequentially through the bottom outlet of the discharge pipe 9 and the fixed mold 11. The second pusher 7 is fixedly mounted on the fixed mold 11 and the feed roller 2 to pull out... The area below the two films, the output end of the second pusher 7 is upward, and a high-temperature cloth 12 is placed between the second pusher 7 and the film pulled out from the feed roller 2. The edge of the high-temperature cloth 12 is pulled and the position is defined. The output end of the second pusher 7 moves upward. An upper groove is opened on the bottom end face of the positioning film. A heating head 13 (a mold that can be heated and maintained at a constant temperature) is fixedly connected to the top end face of the output end of the second pusher 7. A lower groove is opened on the top end face of the heating head 13. The upper groove and the lower groove are pressed together after the second pusher 7 rises.

[0016] It should be noted that the foot bath bag mentioned in this invention is a composite film. This composite film is formed by pressing and bonding two layers of film together. The film from the feeding roller 1 (i.e., the upper layer of the composite film) has several through holes formed by a punching component. The film from the unfeeding roller 2 (i.e., the lower layer of the composite film) has an air inlet pipe (i.e., the pipe material stored in the hopper 4) fixedly pressed and bonded. The pressing and bonding components are a third pusher 17 and a third base plate 18 arranged sequentially from top to bottom. The upper and lower layers of film are both pulled to pass the top surface of the third base plate 18. The bottom end of the third pusher 17 is also provided with a pressing and bonding component, so that the upper and lower layers of film are pressed and bonded. The bottom end surface of the pressing and bonding component at the bottom end of the third pusher 17 has a groove. The groove area means that the upper and lower layers of film are not pressed and bonded here. The unpressed area will form an inner cavity passage on this composite film. The air inlet pipe that has been pressed and fixed on the lower layer of film is located at one end of the inlet and outlet of this inner cavity passage. The elastic band pressing component here folds (folds in half in the width direction) and presses the composite film produced here (the pressing head 13 is perpendicular to the conveying direction of the composite film and is set parallel to the horizontal plane, pressing the composite film passing under the pressing head 13 up and down repeatedly), forming several bag-like structures connected together. The opening of each bag is the two sides of the original flat composite film. Elastic bands are pressed at the entrance and exit of the bag-like structures. High temperature resistant elastic bands are selected, stretched, and made parallel to the length direction and close to the opening of the bag structure. Then, they are pressed to fix the elastic bands to the bag structure. Then, the cutting equipment is used to cut them at intervals. The elastic band pressing component and the segment cutting component here can be referred to as the production equipment of shower caps. They are relatively common in the production field of products with elastic bands at the bag openings, so they will not be described in detail in this article.

[0017] A crossbeam is fixedly installed between the discharge pipe 9 and the slide rail 5. A connecting rod 14 is rotatably sleeved on the crossbeam. A notch is opened on the side wall at the bottom outlet of the hopper 4. A push rod is hinged to the top of the connecting rod 14. The end of the push rod away from the connecting rod 14 extends through the notch into the bottom of the inner cavity of the hopper 4. A second slider 15 is fixedly connected to the end of the push rod located in the inner cavity of the hopper 4. The cross-sectional diameter of the second slider 15 is larger than that of the notch. The second slider 15 collides with the pipe material stored in the hopper 4. The connecting rod 14 itself is a two-section structure, each section being a straight rod. The included angle between the two sections is... At a suitable angle (e.g., 120~160 degrees), the pivot of the connecting rod 14 is located at the junction of the two sections of the structure. The cross-sectional area of ​​the notch is larger than that of the push rod. The first slider 10 on the slide rail 5 needs to pick up the tube material from the bottom of the discharge pipe 9 each time. That is, the first slider 10 will move along the slide rail 5 each time. The first slider 10 will hit the bottom of the connecting rod 14 on the moving path, thereby driving the connecting rod 14 to rotate. The connecting rod 14 pushes the push rod, and the push rod goes deeper into the bottom of the hopper 4, thereby driving the slider to stir the bottom of the hopper 4 and prevent the tube material at the bottom of the hopper 4 from getting blocked.

[0018] A spring is hinged at the bottom outlet of the discharge pipe 9. One end of the spring is pressed by a spring structure, and the other end of the spring is pressed against the bottom outlet of the discharge pipe 9. A cylinder is fixedly installed on the robot arm at the bottom of the discharge pipe 9. The output end of the cylinder contacts the edge of the spring on its moving path, which can temporarily open the spring at the bottom outlet of the discharge pipe 9. When the robot arm passes this spring, the spring is opened by the cylinder. When the spring is opened, the pipe material is received and clamped by the robot arm, and the spring is reset to reseal the bottom outlet of the discharge pipe 9.

[0019] A printing component 16 is also fixedly installed between the feeding roller 1 and the feeding punching assembly. The printing component 16 is a pad printing machine specially equipped with a robotic arm. The pad printing machine here is used to mark and color the upper film surface to facilitate the alignment of calibration equipment.

[0020] Working Principle: The foot bath bag production device mentioned in this invention provides a robotic arm capable of placing the tube, realizing automated transportation of the air inlet pipe, thereby achieving the complete automated production of the foot bath bag. The material processing component punches holes in the upper layer of the double-layer film and heat-presses the air inlet pipe onto the lower layer of film. After the upper and lower layers of film are pressed together, they form a composite film. During the pressing process, a certain area needs to be left unpressed. The unpressed area becomes the inner cavity passage of the composite film. The air inlet pipe is located at one end of this passage. It is formed in one step by high-temperature heat pressing, which is different from roller rolling and manual placement of the tube, thus improving production efficiency.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of the claims.
