[0002] Kraft paper bags are packaging bags made of kraft paper and are commonly used to package a variety of items. Kraft paper is a type of paper made from treated wood pulp that has high strength and durability, making it ideal for packaging bags. Kraft paper bags come in two main colors: white and brown. Most customers choose to use natural brown to make paper bags because this does not require the use of bleaching agents and is good for environmental protection.

The device is It is convenient to collect and count paper bags, and the number of paper bags in each box can be accurately controlled. However, in actual use, due to the material limitations of the kraft paper bags themselves, they are prone to rupture. Nowadays, manufacturers choose to replace the ingredients of kraft paper bags or paste reinforcing strips on the edges of kraft paper bags after unloading to strengthen the tightness of kraft paper bags. Some manufacturers choose to use manual pasting of reinforcing strips during the unloading process, but the efficiency of manual pasting is low, and when the existing equipment pastes the reinforcing strips during the unloading process, the glue content on one side of the reinforcing strips is different, which makes the existing equipment prone to skewed reinforcing strips during actual pasting. Re-pasting greatly reduces the unloading efficiency of kraft paper bags.

The heater 43 is electrically connected to the control center 20 to ensure the normal operation of the device.

[0049] Working principle: In the initial state, each clamp 11 of the transmission device 10 clamps the processed kraft paper bag. The transmission device 10 is composed of a transmission plate, a drive motor, a connecting shaft and other components (this is the prior art and will not be described in detail later). The transmission device 10 is turned on to drive several clamps 11 to move to the top of the left placement slot of the transmission device 10. When the transmission device 10 is turned on, the control center 20 is used to turn on the rotation drive component 22. The rotation of the rotation drive component 22 drives the rotating shaft 220 to rotate. The rotation of the rotating shaft 220 drives the first movable wheel 221 to rotate. The first movable wheel 221 rotates through the adjusting arm 222 to drive the rotating column 223 to rotate. The rotation of the rotating column 223 drives the return groove plate 23 to make a linear reciprocating motion. The return groove plate 23 moves through the connecting plate 230 drives the fixing member 231, the mounting plate 232 and the two mounting members 233 to move, and the movement of the mounting member 233 drives the strip sticking roller 234 to make a linear reciprocating motion at the reinforcing strip sticking position of the kraft paper bag. The strip sticking roller 234 is pre-equipped with a cutting device. When the strip sticking roller 234 linearly reciprocates to stick the reinforcing strip on the surface of the kraft paper bag at the rear end of the strip sticking roller 234, the cutting device cuts off the reinforcing strip, and then the transmission device 10 continues to transmit the next clamp 11 together with the kraft paper bag to the rear end of the strip sticking roller 234. In this way, the device continuously sticks the reinforcing strip on the kraft paper bag during production and blanking, avoiding manual sticking of the reinforcing strip after subsequent blanking, which further prolongs the production time of the kraft paper bag, thereby reducing the production efficiency of the device and facilitating user use;

[0050] When the return groove plate 23 makes a linear reciprocating motion, it synchronously drives the two first tooth plates 235 to move. The movement of the first tooth plate 235 drives the two second tooth plates 31 to reciprocate through the second shaft rod 30. When the first tooth plate 235 moves to the left, the second tooth plate 31 rotates to drive the screw rod 32 to rotate. The rotation of the screw 32 drives the through rod 33 to move toward the kraft paper bag at the bottom of the pressure plate 34. The movement of the through rod 33 drives the pressure plate 34 to move toward the kraft paper bag and apply pressure. The kraft paper bag at the bottom of the pressure plate 34 is the kraft paper that has been moved by the transmission device 10 after the reinforcement strip is attached. The pressure of the pressure plate 34 can increase the adhesion strength and adhesion area between the adhesive surface of the reinforcing strip and the kraft paper bag, and avoid the gap between the reinforcing strip and the surface of the kraft paper bag, which reduces the adhesion quality of the device. When the first tooth plate 235 moves to the right, the pressure plate 34 is reset in the same way. At this time, the kraft paper bag loses the pressure of the pressure plate 34 and can move normally, and the corresponding strip-sticking roller 234 completes the strip-sticking process for the next kraft paper bag. Therefore, the device can simultaneously apply pressure to the previous kraft paper bag while strip-sticking the kraft paper bag, thereby improving the quality and efficiency of the device sticking the reinforcing strip, and facilitating the use of users;

[0051] In the above steps, when the first movable wheel 221 rotates, the second movable wheel 241 is driven to rotate through the movable belt 242, and the second movable wheel 241 rotates to drive the first toothed disc 244 to rotate through the rotating rod 243, and the first toothed disc 244 rotates to drive the two third toothed discs 41 to rotate, and the third toothed disc 41 rotates through the third shaft 40 and the fan blades 42. The wind blown by the fan blades 42 and the rotating rod 243 increases the temperature to form hot wind under the heating of the heater 43. In the process of this step, the kraft paper bag at the pressure plate 34 is moved to the conveying device 10 by the conveying device 10 At the temperature regulating device 4, the hot air blown by the temperature regulating device 4 is directly blown to the connection between the reinforcing strip and the kraft paper bag to increase the temperature of the connection between the reinforcing strip and the kraft paper bag, and then the transmission device 10 continues to transmit the clamp 11 and the kraft paper bag to the top of the collecting tank 12, so that the adhesive surface of the reinforcing strip is on the surface of the kraft paper bag and dries quickly, avoiding the reinforcing strip from being misaligned in the pasting position of the kraft paper bag due to the incomplete drying between the adhesive surface of the reinforcing strip and the kraft paper bag during the unloading process, thereby further extending the unloading time of the kraft paper bag, improving the pasting quality of the device and the unloading transmission efficiency, and facilitating user use;

[0052] When the second movable wheel 241 rotates, the first bevel gear 240 is driven to perform reciprocating rotation through the first shaft 24, the first bevel gear 240 rotates to drive the second bevel gear 25 to rotate, the second bevel gear 25 rotates to drive the fourth toothed disc 251 to rotate through the fourth shaft 250, the fourth toothed disc 251 rotates to drive the second toothed plate 252 to perform reciprocating linear motion on the outer surface of the sliding rod 253, the second toothed plate 252 moves through the mounting rod 254 and the through slot 200 to drive the blanking plate 255 to perform reciprocating linear motion, The bottom of the unloading plate 255 is a kraft paper bag that has been heated by the temperature control device 4. At this time, the unloading plate 255 moves downward to push the kraft paper bag from the clamp 11 to the collecting trough 12 for collection, and the conveying device 10 continues to convey the next clamp 11 and kraft paper bag when the unloading plate 255 reciprocates in a straight line to reset. Therefore, the device can complete the pasting of the reinforcement strip during the process of conveying the unloading material while improving the pasting quality of the device and the unloading transmission efficiency. The device only uses one driving source, which reduces the cost of the device and is convenient for users to use.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
