[0022] See also Figure 1The paper bag 3 is wound around the rotating roller 2, and the number of rotating rollers 2 is arranged according to the required strength of the paper bag handle. The more rotating rollers 2 are arranged, the stronger the paper bag handle is. A plurality of glue coating structures 4 are arranged on one side of the rotating roller 2. The bottom of the glue coating structure 4 contacts the surface of the paper 3. The glue coating structure 4 can be connected to the box body for storing glue, so as to avoid the problem of constant replacement of glue in the glue coating structure 4. The two ends of the glue coating structure 4 are fixedly connected to the support rod. A pressing roller 5 is symmetrically arranged up and down on one side of the glue coating structure 4 away from the rotating roller 2. Paper 3 is arranged between the pressing rollers 5. The pressing rollers 5 are pressed together, so that multiple papers 3 are merged and the papers 3 are bonded by glue 42. The two ends of the pressing roller 5 are rotatably connected to the support rod. A heating plate 6 is symmetrically arranged up and down on the side of the pressing roller 5 away from the glue coating structure 4. Paper 3 is arranged between the heating plates 6. The two ends are fixedly connected to the connecting rod, and a heating tube is provided in the heating plate 6. The paper 3 is heated by the heating plate 6 so that the glue 42 solidifies, so that the papers 3 are firmly adhered to each other. A transverse cutting structure 7 is provided on the side of the heating plate 6 away from the pressing roller 5. The transverse cutting structure 7 contacts the paper 3. The paper 3 can be divided into several paper bag handles of the required width by the transverse cutting structure 7. Two transversely arranged traction rollers 8 are provided on the side of the transverse cutting structure 7 away from the heating plate 6. One end of the traction roller 8 is connected to the driving unit for transmission. The driving unit can be a servo motor. Both ends of the traction roller 8 are rotatably connected to the support rod. Paper 3 is arranged between the traction rollers 8. The traction roller 8 is driven to rotate by the driving unit so that multiple paper 3 can be pulled. A longitudinal cutting structure 9 is provided on the side of the traction roller 8 away from the transverse cutting structure 7. Both ends of the longitudinal cutting structure 9 are connected to the support rod. The longitudinal cutting structure 9 contacts the paper 3. The transverse cutting structure 7 is used to cut the paper bag handle to the required length, thereby completing the processing of the paper bag handle.

[0023] See also Figure 2 The glue coating structure 4 includes an outer tube 41, and glue 42 is provided in the outer tube 41. A rectangular groove is provided at the bottom of the outer tube 41, and the rectangular groove is in contact with the outer ring of the smear roller 43. The contact between the rectangular groove and the outer ring of the smear roller 43 can save the amount of glue 42. The outer ring of the smear roller 43 is in contact with the paper 3, and the two ends of the smear roller 43 are rotatably connected to the inner walls on both sides of the outer tube 41. The paper 3 enters and contacts with the smear roller 43, and the smear roller 43 and the outer tube 41 rotate to bring out the glue 42 in the outer tube 41, so that the glue 42 is smeared on the paper 3.

[0024] See also Figure 3The horizontal cutting structure 7 includes a knife box 71, and a plurality of knife grooves are equidistantly provided on one side of the knife box 71. A first cutting blade 73 is provided in the knife groove, and the knife groove clamps 80% of the first cutting blade 73 so that it will not fall off completely during replacement, thereby facilitating replacement of one of the first cutting blades 73. The first cutting blade 73 is used to cut the paper 3 into several paper bags of the required width. One side of the first cutting blade 73 contacts the inner angle of the L-shaped block 72, and the two ends of the L-shaped block 72 are bolted to the two ends of the knife box 71. When one of the first cutting blades 73 becomes blunt, for easy replacement, it is only necessary to remove the bolts and the L-shaped block 72 to replace one of the first cutting blades 73, which is faster and more efficient.

[0025] See also Figure 4 The longitudinal cutting structure 9 includes a symmetrically arranged electric telescopic rod 91, which is fixedly connected to the support rod. The output end of the electric telescopic rod 91 is connected to the top of the two ends of the pressing plate 92. The bottom of the pressing plate 92 is fixedly connected to the transversely arranged second cutting blade 93. A pressing platform 94 is provided at the lower end of the second cutting blade 93. The two ends of the pressing platform 94 are fixedly connected to the connecting rod. A paper 3 is placed between the pressing roller 5 and the second cutting blade. The electric telescopic rod 91 drives the pressing plate 92 to press down, and the pressing plate 92 drives the second cutting blade 93 to cut the paper 3 to obtain a paper bag handle of the required length, thereby completing the processing of the paper bag handle.

[0026] The output ends of the electric telescopic rods 91 at both ends are rotatably connected to the two ends of the pressing plate 92, which can avoid the error of the two electric telescopic rods 91 during long-term use, resulting in the second cutting blade 93 being broken due to the setback.

[0027] The pressing table 94 is cylindrical, and a horizontal surface is opened on the top of the pressing table 94. The pressing table 94 is lower than the traction roller 8 at the lower end. The horizontal surface opened on the top of the pressing table 94 makes it more suitable for the second cutting blade 93 to cut the paper 3, thereby preventing the misalignment of the second cutting blade 93 during cutting from affecting the second cutting blade 93. The pressing table 94 is lower than the traction roller 8 at the lower end, which can cause the paper 3 to bend under the action of gravity after cutting and will not fall off the pressing table 94.

[0028] The specific operation process of this utility model is as follows: the driving unit drives the traction roller 8 to rotate and pull multiple strips of paper 3, so that the paper 3 comes into contact with the smearing roller 43, and the smearing roller 43 and the outer tube 41 rotate to bring out the glue 42 in the outer tube 41, so that the glue 42 is smeared on the paper 3, and then pressed by the pressing roller 5, so that the multiple strips of paper 3 are merged and the paper 3 is bonded by the glue 42, and then the paper 3 is pulled into between the overtime plates, and the paper 3 is heated by the heating plate 6 to cause the glue 42 to solidify, so that the paper 3 is firmly adhered to each other. After the paper 3 is solidified between the heating plates 6, it passes through the first cutting blade 73, thereby dividing the paper 3 into several strips of the required width of the paper bag handle, and finally is pulled into the pressing table 94, and the pressing plate 92 is pressed down by the electric telescopic rod 91, and the pressing plate 92 drives the second cutting blade 93 to cut the paper 3 to obtain the paper bag handle of the required length, thereby completing the processing of the paper bag handle.

[0029] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
