[0002] The paper bag production process is to fold paper into a bag shape, then apply adhesive on the seams and the bottom, and use a bag-making machine to press and bond the seams and the bottom of the bag to make a finished paper bag. As long as the material of the bag contains a part of paper, it can be collectively called a paper bag. According to the material, it can be divided into: white cardboard bags, white board paper bags, coated paper bags, and kraft paper bags.

[0003] During the production process of paper bags, some adhesives are applied to splice and fix the paper bags. It takes a long time for the adhesive to dry naturally, which affects the production efficiency of the paper bags. When the adhesive is dried, the position where the adhesive is applied on the paper bags is prone to warping and deformation, thus affecting the product quality. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a dryer for paper bag manufacturing, comprising a drying cabinet 1, air outlet holes 2 are opened on both sides of the drying cabinet 1, a cabinet door 3 is rotatably connected to the front of the drying cabinet 1, an observation window 25 is installed on the cabinet door 3, a switch handle 26 is installed on one side of the cabinet door 3, an anti-skid pad 27 is connected to the bottom of the drying cabinet 1, and anti-skid patterns are arranged under the anti-skid pad 27. The staff can observe the drying situation of the paper bag through the observation window 25, and the anti-skid pad 27 can increase the friction with the ground, thereby preventing the drying cabinet 1 from sliding during operation and improving the stability of the operation.

[0023] A hot air box 4 is installed under the drying cabinet 1, and connecting grooves 5 are opened on the inner walls on both sides of the drying cabinet 1. The drying cabinet 1 is slidably installed with a dustproof mesh plate 6 through the connecting grooves 5. A pull ring 19 is connected to the dustproof mesh plate 6. Connecting strips 20 are connected on both sides of the dustproof mesh plate 6. The connecting strips 20 slide in the connecting grooves 5. Positioning grooves 21 are opened on the connecting strips 20. Through the sliding of the connecting strips 20 in the connecting grooves 5, the staff can quickly complete the positioning and installation of the dustproof mesh plate 6, thereby preventing dust from entering the drying cabinet 1 and contaminating the paper bags.

[0024] A plurality of support rods 7 are connected inside the drying cabinet 1. A groove 22 is provided inside the drying cabinet 1. A second spring 23 is connected inside the groove 22. A positioning block 24 is connected to one end of the second spring 23. One side of the positioning block 24 is spherical and fits into the positioning groove 21. The spherical surface on one side of the positioning block 24 enables the connecting strip 20 to flexibly push the positioning block 24 to move, thereby facilitating the staff to disassemble and assemble the dustproof mesh plate 6 and clean the dustproof mesh plate 6 in time to avoid dust clogging the dustproof mesh plate 6 due to long-term use.

[0025] Fixed plates 8 are connected to both ends of the support rod 7, and multiple sliding plates 9 are slidably connected to the support rod 7. A first spring 10 is connected between the multiple sliding plates 9. A through hole 17 is opened on the fixed plate 8, and a vent 18 is opened on the sliding plate 9. The sliding plate 9 is connected to the fixed plate 8 through the first spring 10. The rebound force generated by compressing the first spring 10 enables the first spring 10 to push the sliding plate 9 to press the paper bag, thereby preventing the paper bag from being blown and avoiding the paper bag from warping and deformation during drying.

[0026] A heating plate 11 is installed on the hot air box 4, a cover 12 is installed inside the hot air box 4, an air inlet 13 is opened on the cover 12, a fixing frame 14 is connected to the inside of the cover 12, a motor 15 is installed on the fixing frame 14, and a fan blade 16 is connected to the output shaft of the motor 15. There are two covers 12 with the same internal structure. A plurality of ventilation holes are arranged on the heating plate 11, and a dustproof mesh plate 6 is arranged above the hot air box 4. By rotating a plurality of fan blades 16 at the same time, the circulation rate of the air inside the drying cabinet 1 is accelerated, so that the high-temperature air can quickly fill the drying cabinet 1, thereby improving the drying efficiency of the paper bags.

[0027] The working principle of the utility model is:

[0028] By pushing the connecting strip 20 into the connecting groove 5, as the connecting strip 20 is pushed in, the connecting strip 20 will push the positioning block 24 into the groove 22 to compress the second spring 23, so that the positioning block 24 is pushed into the positioning groove 21 by the rebound of the second spring 23, and the dustproof mesh plate 6 is fixed inside the drying cabinet 1, so as to prevent dust from entering and contaminating the paper bags, and then the paper bags are placed on the sliding plate 9. As the number of paper bags placed increases, the sliding plate 9 will be squeezed and pushed by the paper bags, so that the sliding plate 9 slides along the support rod 7 to compress the first spring 10, so that the rebound of the first spring 10 pushes the sliding plate 9 to press and fix the stacked paper bags, so as to prevent the paper bags from sliding during drying and avoid warping and deformation of the paper bags, and then close the cabinet door 3 and start the motor 15, so that the motor 15 rotates the fan blades 16, and at the same time the heating plate 11 heats the surrounding air, so that the high-temperature air is blown to the paper bags through the rotating fan blades 16, and the paper bags are dried to improve the air-drying and bonding efficiency of the adhesive.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
