TECHNICAL FIELD
[0001] The utility model relates to dehumidification bag technical field, specifically to dehumidification bag packing machine. BACKGROUND
[0002] The packaging machine is an equipment that can package and store products, protects the products and makes them beautiful. After the production of dehumidification bags is completed, a batch of dehumidification bags are loaded into packaging bags through the openings of the packaging bags, and the packaging bags are packaged by the packaging machine, so that the openings are closed. The packaging machine usually consists of a fixing structure for fixing the packaging bags and the dehumidification bags loaded therein and a sealing structure arranged above the fixing structure. The packaging bags are fixed on the fixing structure, and the sealing structure can quickly close the packaging bags to achieve packaging processing. The packaging efficiency is high, and the packaging processing precision is high, which effectively prevents the loaded dehumidification bags from falling out.
[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has some defects. In the packaging process of the existing packaging machine, the sealing structure generates high temperature and melts the edges of the packaging bags, so that the edges of the packaging bags are re-adhered together to achieve the effect of packaging processing. Therefore, when packaging and processing the plastic packaging bags with a relatively large thickness, the sealing structure needs to stay at the edges of the packaging bags for a relatively long time, which easily causes the packaging bags to be adhered to the sealing structure for a long time and generates the adhesion phenomenon. When the sealing structure is lifted up, the packaging bags cannot be separated from the sealing structure, which easily causes the adhered packaging bags to be pulled apart by the lifted sealing structure, thereby affecting the success rate of packaging processing. UTILITY MODEL CONTENT
[0004] The utility model aims at the defects and deficiencies of the prior art and provides a dehumidification bag packaging machine with good separation effect and high processing success rate.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dehumidification bag packaging machine includes a processing table and a first support fixedly arranged on one side of the top surface of the processing table. A downward pressing fixing cylinder is fixedly arranged at the top end of the first support. A second support is fixedly arranged on the other side of the top surface of the processing table. A sealing device is fixedly arranged at the top end of the second support. The sealing device includes a second downward pressing cylinder and a hot melting shaft arranged on the bottom end of the downward pressing shaft of the second downward pressing cylinder. The bottom end cross section of the downward pressing shaft of the second downward pressing cylinder is a triangular structure. A separation device is arranged on one side of the second downward pressing cylinder and adheres to the outer side of the downward pressing shaft of the second downward pressing cylinder at the bottom end. After the second downward pressing cylinder is lifted up, the separation device separates the packaging bag from the hot melting shaft.
[0006] Further improvement: a positioning groove is arranged on the upper surface of the processing table.
[0007] Further improvement is that the second lower pressing cylinder is provided with a quick drying device, the quick drying device comprises a pump air machine arranged on one side of the second lower pressing cylinder and an exhaust pipe arranged at the bottom end of the pump air machine, and the bottom end of the exhaust pipe is aligned with the hot melting shaft.
[0008] Further improvement is that the separating device comprises a fixing frame fixedly connected to one side of the second lower pressing cylinder and a horizontal extension rod arranged at the bottom end of the fixing frame, and an inclined scraper is movably clamped at the end of the extension rod, and one side of the inclined scraper is attached to the outer side of the lower pressing shaft of the second lower pressing cylinder.
[0009] Further improvement is that the bottom end of the fixing frame is integrally formed with a horizontal sliding groove, the outer wall of the end of the extension rod is slidingly arranged in the inner wall of the sliding groove, and an outward pushing spring is arranged between the end of the extension rod and the inner wall of the sliding groove.
[0010] After the above technical scheme is adopted, the packaging bag is separated from the hot melting shaft at the bottom of the second lower pressing cylinder by the inclined scraper of the separating device attached to the lower pressing shaft of the second lower pressing cylinder when the second lower pressing cylinder is lifted after the sealing of the packaging bag is completed, so that the phenomenon of adhesion between the hot melting shaft and the packaging bag and the failure to separate them is prevented, the hot melting shaft that rises does not re-pull open the packaging bag, and the success rate of packaging is ensured.
