[0015] Beneficial effects: The advantages and positive effects of this invention are:

[0016] (1) The packaging bag is squeezed by rotating the circular roller I and the electric roller, thereby squeezing out the air in the packaging bag. The air in the packaging bag is squeezed out again by moving multiple guide ropes, thereby avoiding the problem that the edges of the packaging bag are not even when the packaging bag is cut due to the expansion of the packaging bag.

[0017] (2) The guide plate makes the packaging bag change from the initial horizontal state to the inclined state, so that when the gas in the packaging bag is squeezed out, the gas is sprayed out in an inclined direction, thereby preventing the squeezed gas from entering the packaging bag behind. The packaging bag is squeezed by the alternating rotation of the circular roller I and the electric roller, which quickly squeezes out the air in the packaging bag and flattens the wrinkles formed on the surface of the packaging bag, thereby improving the cutting accuracy.

[0018] (3) By rotating the paddle and the plate, a pulling force is generated to the right on the packaging bag, thereby breaking the adhesive joint between the packaging bags. Since the cutting machine has already cut the packaging bag, when the paddle and the plate are rotated to pull the packaging bag, the pulling force will act on the cut part of the packaging bag, thereby avoiding the problem of tearing the packaging bag when the paddle and the plate are rotated to pull the packaging bag, thus avoiding the problem of adhesive joint between the packaging bags.

[0019] (4) When the paddle and the plate pull the packaging bag horizontally to the right, they move upward in an arc, thereby driving the packaging bag to move upward in an arc, thereby increasing the pulling force of the paddle and the plate on the packaging bag, so that the paddle and the plate can quickly break the adhesive part of the packaging bag.

[0020] (5) The round roller II presses against the packaging bag and crushes the packaging bag, thereby flattening the cut edge of the packaging bag and preventing the packaging bag from curling. The round roller II and the paddle work together to create a pulling force on the packaging bag again, thereby improving the crushing effect of the round roller II on the packaging bag and making the cut edge of the packaging bag flat.

[0021] (6) The packaging bag is squeezed by the operation of the electric pulley, so that a groove is formed in the middle of the packaging bag. When the packaging bag slides out of the guide plate, the groove in the middle of the packaging bag is aligned with the groove formed by the previous packaging bag, thereby preventing the packaging bag from shifting. Compared with the horizontal packaging bag, the front and back of the packaging bag with the groove are placed on top of the previous packaging bag, thereby reducing the phenomenon of the front and back edges of the packaging bag lifting up, and thus improving the neatness of the packaging bag.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] A powder packaging bag cutting device for easy positioning, according to Figures 1-5 As shown, it includes a cutting machine 1, a base plate 2, and a cutting machine 3; the base plate 2 is installed on the right side of the cutting machine 1; the cutting machine 3 is installed on the upper surface of the base plate 2; the cutting machine 3 is connected to the cutting machine 1.

[0039] It also includes a motor I202, a connecting rod I203, a circular roller I204, an electric roller 205, guide ropes 206, and elastic elements I207; the motor I202 is installed on the front right side of the cutting machine 1; two connecting rods I203 are rotatably connected to the right side of the cutting machine 1; the output shaft of the motor I202 is fixedly connected to the front connecting rod I203; a circular roller I204 is slidably connected to all connecting rods I203; an electric roller 205 is slidably connected to all connecting rods I203; multiple guide ropes 206 are connected between the electric roller 205 and the circular roller I204, and the guide ropes 206 are made of elastic material; an elastic element I207 is fixedly connected between the circular roller I204 and each connecting rod I203; another elastic element I207 is fixedly connected between the electric roller 205 and each connecting rod I203.

[0040] It also includes a guide plate 201; the guide plate 201 is fixedly connected to the upper surface of the base plate 2.

[0041] The left side of the guide plate 201 is set in an inclined shape to guide the packaging bag 4.

[0042] Before cutting the packaging bag 4: two rolled packaging bags 4 are placed into the cutting machine 1, and then the movable end of the packaging bag 4 is manually pulled through the lower part of the electric roller 205, as shown. Figure 4 As shown, the following will discuss the cutting process of a roll of packaging bags 4. Before cutting, for some packaging bags 4 that require perforation, perforation is performed using a perforation device. This can easily lead to gas entering the packaging bag 4 during transport, causing it to expand. Consequently, the cut edges of the packaging bag 4 will not be even, affecting the cutting accuracy. Before cutting, the control motor I202 is started. The output shaft of motor I202 rotates, driving the connecting rod I203 to rotate clockwise around the front of the cutting machine 1. The rotation of connecting rod I203 drives the circular roller I2... 04 and the electric roller 205 rotate, which in turn squeezes the packaging bag 4 by rotating the circular roller I 204 and the electric roller 205. When the circular roller I 204 and the electric roller 205 rotate and touch the guide plate 201, the corresponding elastic element I 207 is compressed by the guide plate 201, thereby squeezing out the air in the packaging bag 4. At the same time, the electric roller 205 is started. The rotation of the electric roller 205 drives the circular roller I 204 to rotate through all the guide ropes 206, thereby driving the packaging bag 4 to continue to move to the right, so as to avoid the problem of uneven edges at the cut when the packaging bag 4 is cut due to the expansion of the packaging bag 4.

[0043] Furthermore, the packaging bag 4 is squeezed alternately by the rotation of the circular roller I 204 and the rotation of the electric roller 205. Since the left side of the guide plate 201 is cut at an angle, when the circular roller I 204 and the electric roller 205 rotate to squeeze the packaging bag 4, the packaging bag 4 will be pressed against the angled left side of the guide plate 201, thereby changing the packaging bag 4 from the initial horizontal state to the angled state. When the gas inside the packaging bag 4 is squeezed out, the gas is ejected in an angled direction, thus preventing the squeezed gas from entering the packaging bag 4 behind. In addition, the alternating compression of the packaging bag 4 by the rotation of the circular roller I 204 and the electric roller 205 quickly squeezes out the air inside the packaging bag 4 and flattens the wrinkles formed on the surface of the packaging bag 4, thereby improving the cutting accuracy.

[0044] After the air inside the packaging bag 4 is squeezed out, the packaging bag 4 continues to move to the right and is below the cutting machine 3. The cutting machine 3 is then controlled to cut the packaging bag 4 to the required length.

[0045] Example 2

[0046] Based on Example 1, according to Figures 6-10As shown, it also includes a traction system; the traction system includes a mounting plate 301, a motor II 302, a connecting rod II 303, a disc 304, a top block 3041, a round tube 305, a cylinder 306, a paddle 3061, a paddle plate 3062, a bracket 307, a sliding sleeve 308, a motor III 309, and an elastic element II 310; two mounting plates 301 are installed on the right side of the guide plate 201; a motor II 302 is installed on the front mounting plate 301; the output shaft of the motor II 302 is fixedly connected to the connecting rod II 303; a disc 304 is fixedly connected to the connecting rod II 303; an annular groove is opened on the disc 304, and two top blocks 3041 are fixedly connected in the annular groove. The top blocks 3041 are made of elastic material, and the annular groove slides circumferentially. A circular tube 305 is connected; multiple through holes 3051 are opened at the rear of the circular tube 305; a cylindrical tube 306 is fixedly connected to the circular tube 305, and multiple air holes are opened at equal intervals on the cylindrical tube 306; multiple paddles 3061, which are made of elastic material, are fixedly connected at equal intervals on the outer ring surface of the cylindrical tube 306; two paddle plates 3062 are fixedly connected to the outer ring surface of the cylindrical tube 306; a bracket 307 is fixedly connected to the rear of the upper surface of the guide plate 201; an arc-shaped groove is opened on the bracket 307, and a sliding sleeve 308 is slidably connected in the arc-shaped groove; the sliding sleeve 308 is rotatably connected to the circular tube 305; a motor III 309 is installed on the rear side of the sliding sleeve 308; the output shaft of the motor III 309 is fixedly connected to the circular tube 305; an elastic element II 310 is fixedly connected between the sliding sleeve 308 and the bracket 307.

[0047] The top block 3041 is provided with an arc-shaped groove to fit the outer side of the round tube 305 and increase the contact area between the top block 3041 and the round tube 305.

[0048] A cylindrical rubber strip is provided at the end of the paddle 3061 away from the cylinder 306 for pulling the packaging bag 4.

[0049] A rubber strip is provided at the end of the lever 3062 away from the cylinder 306 for pulling the packaging bag 4.

[0050] When pulling the packaging bag 4: Due to incomplete cutting of the packaging bag 4 by the cutting machine 3, there is adhesion between the front and back bags. This causes the packaging bag 4 to shift during subsequent conveying due to the adhesion, affecting the cutting accuracy and the flatness of the subsequent stacking of the packaging bag 4. When the cutting machine 3 cuts the packaging bag 4, the left cutting edge of the packaging bag 4 is blocked by the cutting machine 3, and the right side of the packaging bag 4 is located below the cylinder 306. Then, the control motor III 309 is started. The output shaft of the motor III 309 rotates, driving the cylinder 305 to rotate. The rotation of the cylinder 305 drives the cylinder 306 to rotate. The rotation of the cylinder 306 drives all the levers 3061 and all the levers 3062 to move towards the cutting machine 1. The front side is rotated counterclockwise, causing both the paddle 3061 and the paddle plate 3062 to touch the packaging bag 4 and pull the packaging bag 4 to the right. At this time, the left side of the packaging bag 4 is blocked by the cutting machine 3, which causes the paddle 3061 and the paddle plate 3062 to rotate and exert a pulling force to the right on the packaging bag 4, thereby breaking the adhesive joint between the packaging bags 4. Since the cutting machine 3 has already cut the packaging bag 4, when the paddle 3061 and the paddle plate 3062 rotate and pull the packaging bag 4, the pulling force will act on the cut part of the packaging bag 4, thereby avoiding the problem of tearing the packaging bag 4 when the paddle 3061 and the paddle plate 3062 rotate and pull the packaging bag 4, thus avoiding the problem of the packaging bags 4 being stuck together.

[0051] Furthermore, since the lever 3061 and lever 3062 exert a horizontal pulling force to the right on the packaging bag 4 when pulling it, in order to increase the pulling force of the lever 3061 and lever 3062 on the packaging bag 4, the motor II 302 is started. The output shaft of the motor II 302 rotates, which drives the connecting rod II 303 to rotate. The rotation of the connecting rod II 303 drives the disc 304 to rotate. The rotation of the disc 304 drives the two top blocks 3041 to rotate. When the top blocks 3041 rotate and touch the circular tube 305, the circular tube 305 is pushed upward in an arc by the top blocks 3041. Simultaneously, the movement of the round tube 305 causes the sliding sleeve 308 to move along the bracket 307 and compress the elastic element II 310. The arc-shaped upward movement of the round tube 305 causes the paddle 3061 and the paddle plate 3062 to move arc-shaped upward as well. This causes the paddle 3061 and the paddle plate 3062 to move arc-shaped upward when pulling the packaging bag 4 horizontally to the right, thereby causing the packaging bag 4 to move arc-shaped upward. This increases the pulling force of the paddle 3061 and the paddle plate 3062 on the packaging bag 4, allowing the paddle 3061 and the paddle plate 3062 to quickly break the adhesive joint of the packaging bag 4.

[0052] When the sliding sleeve 308 moves to the top of the support 307, the sliding sleeve 308 is restricted by the support 307 and no longer moves upward. At this time, the top block 3041 will be bent by the pressure of the round tube 305. At this time, the disc 304 continues to rotate, which causes the top block 3041 to pass over the round tube 305, and then the sliding sleeve 308 is moved and reset by the rebound force of the elastic element II 310. The movement of the sliding sleeve 308 drives the round tube 305 to move and reset, so as to facilitate the processing of the next packaging bag 4.

[0053] Example 3

[0054] Based on Example 2, according to Figures 11-12 As shown, it also includes a wrinkle removal system; the wrinkle removal system includes an air guide pipe 311, a support frame 401, a fixing plate 402, a connecting frame 403, a circular roller II 404, a cover 405, a guide plate 406, and an electric pulley 407; the air guide pipe 311 is rotatably connected to the circular pipe 305, and the air guide pipe 311 is located outside the through hole 3051; the support frame 401 is fixedly connected to the right side of the upper surface of the guide plate 201; two fixing plates 402 are fixedly connected to the support frame 401; a connecting frame 403 is fixedly connected to the lower part of each fixing plate 402; a circular roller II 404 is rotatably connected to each connecting frame 403; two covers 405 are fixedly connected to the right side of the guide plate 201; a guide plate 406 is fixedly connected to the lower inner side of each cover 405; all guide plates 406 are fixedly connected to the guide plate 201; an electric pulley 407 is installed on the upper inner wall of each cover 405.

[0055] Both the cover 405 and the guide plate 406 are set at an angle to guide the cut packaging bag 4.

[0056] The front and rear of the electric pulley 407 are set in a conical shape for squeezing the packaging bag 4.

[0057] Elastic element I207 and elastic element II310 are springs.

[0058] When de-wrinkling the packaging bag 4: The external pump for air supply is connected to the air pipe 311 beforehand. Because the packaging bag 4 is easily curled at the cut point due to pressure during cutting by the cutting machine 3, this causes edge curling, severely reducing the quality of the packaging bag 4. After the packaging bag 4 is cut, the cylinder 306 continues to rotate in the above manner, thereby driving the two levers 3062 to rotate. The rotation of the two levers 3062 respectively squeezes a fixed plate 402, causing the fixed plate 402 to move obliquely downwards, thereby driving all connected components to move, and causing the roller II 404 to move obliquely downwards and contact the packaging bag 4. As the cylinder 306 continues to rotate, the levers... 3062 will continuously squeeze the fixed plate 402, causing the roller II 404 to press against the packaging bag 4 and crush it, thus flattening the cut edge of the packaging bag 4 and preventing the packaging bag 4 from curling. When the cylinder 306 continues to rotate, the paddle 3061 will contact the packaging bag 4 and drive the packaging bag 4 to move to the right. When the roller II 404 crushes the packaging bag 4, the direction of the force is from right to left, thus making the forces of the roller II 404 and the paddle 3061 opposite. Through the cooperation of the roller II 404 and the paddle 3061, a pulling force is applied to the packaging bag 4 again, thereby improving the crushing effect of the roller II 404 on the packaging bag 4 and making the cut edge of the packaging bag 4 flat.

[0059] After being crushed by the roller II 404, the packaging bag 4 is conveyed to the guide plate 406 through the cylinder 306. During this conveying process, the packaging bag 4 is prone to displacement, making the subsequent collection and packaging process cumbersome. When the packaging bag 4 enters the guide plate 406, it falls onto the upper surface of the guide plate 406 and is supported by it. Then, an external pump is controlled to supply air into the cylinder 305 through the air pipe 311. The gas then flows along the cylinder 305 into the cylinder 306 and is discharged through the air holes on the cylinder 306 towards the guide plate. Inside the guide plate 406, the electric pulley 407 is simultaneously controlled to squeeze the packaging bag 4, forming a groove in the middle of the packaging bag 4. When the packaging bag 4 slides out of the guide plate 406, the groove in the middle of the packaging bag 4 is aligned with the groove formed by the previous packaging bag 4, thus preventing the packaging bag 4 from shifting. Compared to the horizontal packaging bag 4, the front and back of the packaging bag 4 with the groove are placed on top of the previous packaging bag 4, thereby reducing the phenomenon of the front and back edges of the packaging bag 4 lifting up, and thus improving the neatness of the packaging bag 4.
