Description

TECHNICAL FIELD

[0001] The present application relates to the field of oxygen absorber bag sealing equipment, in particular to an oxygen absorber bag sealing device. BACKGROUND

[0002] Oxygen absorber bag sealing devices are widely used in the packaging of products sensitive to oxidation, such as food, medicine, electronic components, etc., to ensure that these products do not deteriorate due to oxidation during storage and transportation. With the increasing market demand, the application range of such devices is also expanding, not only improving production efficiency, but also significantly improving product quality and safety. Currently, the common oxygen absorber bag sealing devices on the market mainly adopt manual feeding mode. Specifically, the operator needs to put a certain amount of oxygen absorber into the feeding barrel first, and then pour it into the feeding groove on the feeding tray by manual weighing. Then, the feeding tray rotates, and the oxygen absorber enters the charging pipe through the intermittent switch, and is finally sealed by the sealing mechanism. In addition, some devices also use simple mechanical auxiliary means, such as vibrating sieve separation equipment, to help evenly distribute the oxygen absorber. However, there is a problem of inconsistent quality caused by manual feeding. Because of the different operation habits of each operator, the amount of each feeding is difficult to be completely consistent, which will cause the quality of the sealed oxygen absorber bag to fluctuate greatly, affecting the stability and reliability of the product.

The feeding mechanism 3 includes a feeding hopper 31, a feeding tray 32, a sweeping tray, and a loading pipe 34. A feeding motor is installed on the frame 1. The feeding tray 32 is fixedly connected to the output shaft of the feeding motor. The feeding hopper 31 is installed on the frame 1, and the discharge port is located above the feeding tray 32. A feeding groove 321 is opened on the feeding tray 32. A sweeping plate 33 for filling oxygen absorber into the feeding groove 321 is provided on the frame 1. An intermittent switch 6 is provided at the lower end of the feeding tray 32 corresponding to the feeding groove 321. The loading pipe 34 is installed below the feeding tray 32 and is provided corresponding to the feeding groove 321. The sealing mechanism 4 is installed on the frame 1 for sealing the film. The cutting box 5 is installed below the sealing mechanism 4. The sealed film passes through the cutting box 5. A cutting mechanism is provided inside the cutting box 5.

[0032] The frame 1, serving as the basic framework of the entire device, is made of high-strength steel, providing excellent rigidity and stability. The film feeding mechanism 2 includes a film roll support and a traction roller. The film roll support holds the rolled film, while the traction roller is driven by a motor to ensure smooth film delivery to the sealing area. The feeding hopper 31 stores the oxygen absorber to be sealed and contains an internal stirrer to ensure uniform distribution of the oxygen absorber. The loading tray 32 is connected to a loading motor, which drives its rotation to achieve quantitative transfer of the oxygen absorber. The sweeping plate 33, fixed to the frame 1, has an arc-shaped edge design, effectively pushing the oxygen absorber into the loading trough 321 as the loading tray 32 rotates.

[0033] The sealing mechanism 4 includes a vertical sealing component 41 and a horizontal sealing component 42. Both have the same structure and adopt ultrasonic sealing. The vertical sealing component 41 consists of two sealing heads, which are arranged vertically. One sealing head is fixed, and the other sealing head is mounted on the frame 1 by a drive motor. The drive motor drives the two sealing heads to come close together and perform sealing.

[0034] The vertical sealing element 41 is located near the body of the feeding tube 34 and is mainly used to seal the two sides. The horizontal sealing element 42 is installed below the outlet of the feeding tube 34 and is responsible for sealing the top and bottom. The guide roller is rotatably connected to the frame 1 and is located near the outlet of the feeding tube 34. Its side surface is made of frosted material to increase friction and prevent the film from slipping.

[0035] A support plate is installed at one end of the discharge port of the feeding pipe 34. The support plate is made of stainless steel, is flat and smooth, which helps to lay the membrane flat.

[0036] The cutting box 5 is mounted on the frame 1 via a lifting assembly 9. The lifting assembly 9 includes a lifting screw and a guide rod. The lifting screw is rotatably connected to the frame 1 and driven by the cutting box 5. A handwheel is installed at one end of the lifting screw to facilitate manual adjustment of the height of the cutting box 5. The guide rod is set through the cutting box 5 to ensure the stability and accuracy of the cutting box 5 when it moves up and down.

[0037] like Figure 2 and Figure 3 As shown, the intermittent switching component 6 consists of a baffle plate 61, a limiting rod 62, and a limiting spring 63. The limiting rod 62 is fixed to the bottom of the feeding tray 32. The baffle plate 61 is rotatably connected to the limiting rod 62 by a pin. The limiting spring 63 is sleeved on the limiting rod 62, with one end fixedly connected to the limiting rod 62 and the other end connected to the baffle plate 61. A door opener 7 and a door closeer 8 are provided on the frame 1 corresponding to the baffle plate 61. Both the door opener 7 and the door closeer 8 consist of a support rod 71 and a limiting roller 72. The limiting roller 72 can squeeze the baffle plate 61, causing the baffle plate 61 to rotate, thereby realizing the opening and closing of the feeding trough 321.

[0038] The implementation principle of the oxygen absorber bag sealing device according to an embodiment of the present application is as follows: the feeding motor drives the feeding disc 32 to rotate, so that the oxygen absorbers enter the respective feeding grooves 321 in turn, and the excess oxygen absorbers are scraped off by the sweeping plate 33 to keep the amount of material in each feeding groove 321 consistent. When the feeding disc 32 rotates to a specific position, the door opener 7 is started, the blocking plate 61 is opened, the oxygen absorbers fall into the feeding pipe 34, and then the door closer 8 makes the blocking plate 61 reset. The sealing mechanism 4 seals the film by hot pressing to form sealed oxygen absorber bags. Finally, the cutter mechanism in the cutting box 5 cuts the sealed bags, and the whole sealing process is completed. This way realizes automatic and precise feeding and sealing, greatly improving the production efficiency and product quality.

[0039] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
