Description

Technical Field

[0001] This utility model relates to the field of dehumidifying bag technology, specifically to production equipment for moisturizing bags. Background Technology

[0002] Moisturizing bags are portable, non-toxic, and easy-to-carry moisturizing devices suitable for various storage spaces. They have automatic moisture release and absorption functions, maintaining a relatively stable humidity environment. Moisturizing bags are usually individually packaged. The inside typically contains a humectant to regulate the humidity of the environment, while the outer layer is a wrapping paper or cloth to hold the humectant. The outer wrapping paper is usually made of breathable or moisture-permeable materials. Moisturizing bags can effectively maintain a relatively stable humidity environment inside the container, preventing damage to the items stored inside due to excessively high or low humidity.

[0003] The inner cavity of the moisturizing pack is filled with a moisturizer. During the production process, a production equipment is needed to fill a predetermined amount of moisturizer into the inner cavity of the packaged paper. The production equipment can inject the moisturizer into the inner cavity of the packaged paper in a quantitative manner through an injection tube, thereby greatly improving the production speed and automation of the moisturizing pack.

[0004] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: after the existing production equipment injects the humectant, since the humectant is generally semi-liquid, some humectant will remain in the injection tube of the production equipment after each injection. This can easily cause the residual humectant in the injection tube to drip onto the processing table, which can easily cause hygiene problems, as well as waste of humectant and large processing losses. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing production equipment for moisturizing packs that achieves high hygiene and minimizes waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a production equipment for moisturizing packs, including a frame and a workbench set at the top of the frame. A lifting frame is provided on the upper surface of the workbench, and a raw material barrel is fixedly provided on the top of the lifting frame. An injection tube that communicates with the raw material barrel is detachably provided on the bottom surface of the raw material barrel. The injection tube includes a conveying tube and a threaded tube set at the top of the conveying tube. A shrinking tube is provided at the bottom of the conveying tube, and a blocking device is fixedly provided at the bottom of the conveying tube.

[0007] A further improvement is that the blocking device includes a connecting rod fixedly installed at the bottom of the conveying pipe and a connecting plate fixedly installed in the middle section of the connecting rod, and a downwardly inclined rubber sheet is fixedly connected to the outer wall of the connecting plate.

[0008] A further improvement is that an opening and closing plate is movably engaged at the bottom end of the shrink tube, and an elastic sheet is provided between the bottom surface of the opening and closing plate and the outer wall of the shrink tube.

[0009] A further improvement is that the top of the connecting rod is provided with a hemispherical guide block.

[0010] A further improvement is that the worktable has several positioning grooves integrally formed.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, during the injection of humectant, the raw material barrel is squeezed, causing the humectant inside the raw material barrel to be forced into the conveying pipe. Subsequently, its own pressure causes the rubber sheet to deform, allowing the humectant to flow out from the gap between the rubber sheet and the conveying pipe. After the conveying is completed, the squeezing of the raw material barrel is stopped, causing the flow pressure generated by the humectant to disappear, thereby allowing the rubber sheet to recover and re-adhere to the inner wall of the conveying pipe, thus sealing the inner wall of the conveying pipe. This prevents the humectant remaining on the inner wall of the conveying pipe from flowing downwards, avoiding hygiene problems and preventing waste. Attached Figure Description

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a production equipment for moisturizing packs, including a frame 1 and a workbench 2 set at the top of the frame 1. A lifting frame 3 is provided on the upper surface of the workbench 2. A raw material barrel 4 is fixedly provided on the top of the lifting frame 3. An injection tube 5 is detachably provided on the bottom surface of the raw material barrel 4 and communicates with it. The injection tube 5 includes a delivery tube 51 and a threaded tube 52 set at the top of the delivery tube 51. A shrink tube 53 is provided at the bottom of the delivery tube 51. A blocking device 56 is fixedly provided at the bottom of the delivery tube 51. The blocking device 56 includes a connecting rod 31 fixedly set at the bottom of the delivery tube 51 and a connecting plate 33 fixedly set in the middle section of the connecting rod 31. A downwardly inclined rubber sheet 34 is fixedly connected to the outer wall of the connecting plate 33. In use, moisturizer is filled into the raw material barrel 4, and the packaging paper to be filled with moisturizer is opened and placed on the workbench 2 at the injection tube 5. Below the raw material barrel 4, the air pressure block on the side of the raw material barrel 4 is connected to the air compressor. The air pressure forces the humectant in the raw material barrel 4 into the conveying pipe 51, and after passing through the shrink tube 53, it is injected into the inner cavity of the packaging paper. When injecting the humectant, the air pressure squeezes the raw material barrel 4, forcing the humectant into the conveying pipe 51. At this time, the humectant has a certain flow pressure, which causes the rubber sheet 34 to deform, allowing the humectant to flow out from the gap between the rubber sheet 34 and the conveying pipe 51. After the conveying is completed, the air pressure is stopped from squeezing the raw material barrel 4, causing the flow pressure of the humectant to disappear. The rubber sheet 34 then recovers under its own elasticity and re-adheres to the inner wall of the conveying pipe 51, thus sealing the inner wall of the conveying pipe 51. This prevents the humectant remaining on the inner wall of the conveying pipe 51 from flowing downward, avoiding hygiene problems and preventing waste.

[0018] The bottom end of the shrink tube 53 is movably engaged with the opening and closing plate 54. An elastic sheet 55 is provided between the bottom surface of the opening and closing plate 54 and the outer wall of the shrink tube 53. This facilitates the opening and closing plate 54 to be opened when the moisturizer is injected, and causes the elastic sheet 55 to generate elastic force. After the injection is completed, the elastic force of the elastic sheet 55 pushes the opening and closing plate 54 back to close it, thereby improving the leak-proof effect and further reducing the leakage of moisturizer.

[0019] The top of the connecting rod 31 is provided with a hemispherical guide block 32, which helps to guide the flowing moisturizer and reduce residue;

[0020] The workbench 2 has several positioning slots 6 integrally formed, which makes it easier to position and place the packaging bags.

[0021] The working principle of this utility model is as follows: When using this utility model, a humectant is placed in the raw material barrel 4, and the packaging paper to be filled with the humectant is opened and placed on the workbench 2 below the injection tube 5. Then, a pneumatic press is connected via a pneumatic block on the side of the raw material barrel 4. The pneumatic pressure forces the humectant in the raw material barrel 4 into the delivery tube 51, and after passing through the shrink tube 53, it is injected into the inner cavity of the packaging paper. During the injection of the humectant, the pneumatic pressure compresses the raw material barrel 4, forcing the humectant into the delivery tube 51. At this time, the humectant... With a certain flow pressure, the rubber sheet 34 is deformed by the pressure, allowing the humectant to flow out from the gap between the rubber sheet 34 and the conveying pipe 51. After the conveying is completed, the pressure of the raw material barrel 4 is stopped, the flow pressure of the humectant disappears, and the rubber sheet 34 recovers under its own elasticity and re-adheres to the inner wall of the conveying pipe 51, thereby sealing the inner wall of the conveying pipe 51. This prevents the humectant remaining on the inner wall of the conveying pipe 51 from flowing downward, avoiding hygiene problems and preventing waste.
