[0041] The following is a detailed description of the working principle of the stand-up bag processing equipment and the processing technology of the stand-up bag processing equipment. Figure 1 The direction of the middle arrow is the direction of coil conveying, which is also the front; the longitudinal direction is the length direction of the coil, and the transverse direction is the width direction of the coil.

[0042] A self-supporting bag processing equipment includes a coil conveying device and a punching device 2, a bag forming device 3, and a bag forming device 4 arranged in sequence along the conveying direction; the punching device 2 punches holes in the coil at intervals in the longitudinal direction, and the position of the through hole 7 is the sealing side 18 of the bag body 10, so the spacing distance is determined according to the width of the bag body; each group has four transversely arranged through holes, and they are arranged in pairs on the left and right. If the length specifications of the left and right bags are consistent, the left and right bags are symmetrically arranged in pairs.

[0043] The bag forming device includes a primary forming component 3 and a secondary forming component 4. The primary forming component includes a first folding plate 8, a left inserting plate 11 and a right inserting plate 12. The two through holes on the left side of the coil 1 are respectively located above and below the left inserting plate 11 and correspond to each other up and down. The two through holes on the right side of the coil are respectively located above and below the right inserting plate 12 and correspond to each other up and down. During the first processing, the material is threaded first. The left side of the coil successively bypasses the left side of the first folding plate 8 and the right side of the left inserting plate 11. The right side of the coil successively bypasses the right side of the first folding plate and the left side of the right inserting plate. Figure 3 The middle coil is wound from bottom to top, so the left and right insert plates are above the first folding plate 8, and the coil enters from the bottom of the first folding plate. The left side of the coil bypasses the left side of the first folding plate and the right end of the left insert plate from bottom to top, and is laid flat on the left insert plate 11. The right side of the coil bypasses the right side of the first folding plate and the left end of the right insert plate from bottom to top, and is laid flat on the right insert plate 12. Two fold lines are formed on both sides of the coil. The fold line formed along the side end of the first folding plate is the fold line between one bag surface and the bottom surface of the bag body, and the fold line formed along the side end of the left or right insert plate is the inner fold line 17 of the bottom surface; at this time, the coil under the first folding plate is one bag surface of the left and right bags, and the left and right sides of the coil are the other bag surfaces of the left and right bags respectively. The coil 1 is the bottom surface 14 of the left and right bags by detours from the left and right insert plates. If both the left insert plate and the right insert plate are below the first folding plate, the coil is wound from bottom to top.

[0044] The secondary molding component 3 includes a second folding plate 9, the width of the second folding plate is consistent with the width of the first folding plate 8, the first folding plate and the second folding plate can be a complete plate, or a folding plate formed by the combination of two left and right plates. In the folding order, the left insert plate 11 and the right insert plate 12 are between the first folding plate 8 and the second folding plate 9, that is to say, the left side and the right side of the semi-molded coil are wound in the order of the one-time molding. If the left insert plate and the right insert plate are both above the first folding plate, the left side and the right side of the semi-molded coil are folded from bottom to top along the two side edges of the second folding plate and covered on the second folding plate. The crease line formed along the side end of the second folding plate is the crease line between the other bag surface and the bottom surface of the bag body. The two crease lines on the left side and the two crease lines on the right side of the molded coil are both up and down. Aligned, the left and right sides of the coil above the second folding plate 9 are the other bag sides of the left and right bags respectively, and the bottom surface is between the two bag sides of the bag body, and the through holes on the bottom surface 25 are covered by the two bag sides of the bag body; if the left and right plug-in plates are both below the first folding plate, the left and right sides of the semi-formed coil are folded from top to bottom along the two side edges of the second folding plate 9 and covered below the second folding plate, usually using the circuitous winding method from bottom to top in the attached figure, the semi-formed coil is completely formed after being folded by the second folding plate, and the left and right bags are formed. The longitudinal cutting is carried out between the left and right sides of the formed coil, so that the left and right bags are separated, and the longitudinal cutting position is the bag opening 13; see the attached Figure 4-6 , the forming coil is sealed and cut transversely from the center line 15 of the same group of through holes of the forming coil, so that the side of the bag body is sealed and separated from the forming coil to form a unit bag body 10. Due to the existence of the through holes, the two bag surfaces corresponding to the through holes are sealed together during sealing, so that the bottom of the unit bag body is close together to form a self-supporting bag; and the starting end of the forming coil after sealing and cutting, that is, the side of the next bag body, is also in a sealed state. Specifically, the self-supporting bag processing equipment also includes a cutting mechanism, which includes a transverse sealing and cutting component and a longitudinal cutting component. The transverse sealing and cutting component is transversely sealed along the center line 15 of the same group of through holes of the forming coil. The transverse sealing and cutting component includes an upper and lower sealing knife and a cutting knife. The cutting knife is set in the middle position of the upper sealing knife. The upper and lower sealing knives are pressed together to seal the forming coil transversely, and the cutting knife cuts the transverse sealing part in half transversely, so that the side of the bag body after sealing and cutting has a sealing edge, and the end of the forming coil also has a sealing edge. The longitudinal slitting component performs longitudinal slitting of the formed coil, and the longitudinal slitting component includes a longitudinal slitting knife, the blade of which faces the fed formed coil and is aligned with the slitting position of the coil, that is, the longitudinal slitting knife is fixed, and as the formed coil moves forward, it can be longitudinally slid. The formed coil is transversely sealed and longitudinally cut once to obtain two self-supporting bag bodies. The utility model adopts one coil to realize the forming process of the self-supporting bag, and forms two bag bodies at one time, which not only avoids the processing problems existing in two coils of coils in the background technology, but also has high production efficiency and good forming quality.

[0045] In order to further improve the production speed and avoid the problem of coil stretching caused by inconsistent forming and sealing and cutting speeds; the coil conveying device includes a continuous traction component 5, which pulls the coil 1 through the punching station, the primary forming station, and the secondary forming station in sequence, that is, the coil punching, primary forming, and secondary forming are continuously pulled, and the coil is punched and formed during the conveying process, which greatly improves the production speed. The coil conveying device also includes an intermittent feeding component and a storage component 6, which is arranged between the continuous traction component 5 and the intermittent feeding component, and the intermittent feeding component intermittently conveys the formed coil to the sealing and cutting station. The formed coils are stored in the storage component 6. The storage component not only stores the formed coils, so that the coil forming operation and the sealing and cutting operation of the formed coils do not interfere with each other, avoiding the problem of the coils being stretched or broken due to the asynchronous front and rear conveying, but also keeps the formed coils taut, so that the intermittent feeding is stable and accurate. When the intermittent feeding component feeds, the transverse sealing and cutting component stops working, and the longitudinal cutting knife performs longitudinal cutting on the fed formed coils. After the intermittent feeding component feeds the material to a fixed length, the transverse sealing and cutting component performs the sealing and cutting operation. The intermittent feeding component gives sufficient time for the sealing and cutting operation to ensure that the sealing is firm and the cutting is complete. The continuous traction component 5 and the intermittent feeding component can use a feeding roller, which is connected to a servo motor, and the servo motor controls the feeding roller to rotate continuously or intermittently. The storage component 6 includes a feeding swing arm 16, a guide roller 19 and a second sensor for detecting the storage amount of the formed coil material. The second sensor, the continuous traction component, the intermittent feeding component and the transverse sealing and cutting component are all connected to the controller. The feeding swing arm 16 is provided with two left and right groups and is swingably set on the frame. The two ends of the guide roller 19 are rotatably set on the two feeding swing arms. The controller controls the feeding speed of the continuous traction component and the intermittent feeding component according to the storage information detected by the second sensor. When the feeding swing arm swings downward and the second sensor detects that the feeding swing arm swings to the low point, the storage is excessive. The controller slows down the conveying speed of the continuous traction component or / and speeds up the conveying speed of the intermittent feeding component and the transverse sealing and cutting speed upon receiving the information. On the contrary, when the feeding swing arm swings upward and the second sensor detects that the feeding swing arm swings to the high point, the storage is insufficient. The controller speeds up the conveying speed of the continuous traction component or / and slows down the conveying speed of the intermittent feeding component and the transverse sealing and cutting speed upon receiving the information. The coil conveying device also includes a material unwinding rack and a tension control component. The coil is placed on the material unwinding rack. The tension control component is arranged between the material unwinding station and the punching station. The structure of the tension control component can adopt the structure of the above-mentioned material storage component. The tension control component can make the coil conveying smoother and prevent the coil from being stretched.

[0046] In order to meet the requirement of punching the coil during the conveying process, the punching can be realized without stopping the material. The punching device 2 includes a punching component 30 and a stopper 26 for assisting the resetting of the punching component to stay at the punching station. The punching component 30 is swingably set on the frame 39. Since the lateral position of the hole punched in the coil 1 will change according to the width of the coil and the function of the hole, in order to be able to be used for punching coils at different positions, the frame 39 is provided with a first adjustment component 31 for adjusting the lateral position of the punching component 30 and the stopper 26. The lateral position of the punching component and the stopper on the frame is adjusted by the first adjustment component to meet the coil punching requirements. The punching component 30 includes a punching knife 25 and a power member 24 for driving the punching knife to move. The power member can use a cylinder to drive the punching knife to punch or reset. The limiting member 26 is arranged at the punching station; before punching, the punching member 30 is arranged vertically and contacts with the limiting member 26, and the punching knife 25 faces the coil 1; when punching, the power member 24 drives the punching knife to move toward the coil and punch holes. At this time, the knife head of the punching knife 25 passes through the coil 1, and the continuously conveyed coil drives the punching member 30 to swing relative to the frame 39, that is, the coil 1 moves, and the punching knife 25 moves accordingly, so that the punching member 30 swings on the frame, so that the punching knife will not hook or tear the coil; after punching, the power member 24 drives the punching knife to reset, and the punching knife 25 is separated from the coil 1. Under the action of gravity and / or the reset force, the punching member 30 swings in the opposite direction until the limiting member 26 blocks the punching member, so that it stays at the punching station and returns to the state before punching. The utility model has a simple structure and is easy to process and assemble. The swing and reset of the punching component do not require additional power components, which greatly reduces the equipment cost. At the same time, it can also realize punching of continuously conveyed coiled materials and realize non-stop punching.

[0047] A support plate 22 is provided below the punching component 30, and a first channel for the punching knife to pass through is provided on the support plate 22. An upper baffle plate 23 is provided above the support plate 22, and a second channel for the punching knife to pass through is provided on the upper baffle plate 23. The support plate 22 supports the coil at the punching station, and the coil is subjected to force during punching, and the punching knife 25 quickly passes through the coil, the second channel and the first channel to achieve punching; the upper baffle plate 23 blocks the area around the punching position of the coil, and when the punching knife retracts, the upper baffle plate blocks the coil, so that the punching knife and the coil are effectively separated to prevent the coil from being taken away by the punching knife. The frame 39 is also provided with a second adjustment component 32 for adjusting the lateral position of the support plate, and the lateral position of the support plate 22 on the frame is adjusted by the second adjustment component to meet the punching position of the coil. The first adjustment component 31 and the second adjustment component 32 both include a slide 28 and a screw 29. The screw is rotatably arranged on a frame 39 and parallel to the crossbeam. The slide 28 is slidably arranged on the crossbeam of the frame, and the slide is threadedly connected to the screw 29. The punching component 30 is swingably arranged on the slide 28 of the first adjustment component 31, and the swinging arrangement can be realized by a rotating shaft 36 and a bearing 35. In the figure, the punching component 30 is connected to the rotating shaft 36, which is installed on the slide 28 through a bearing 35. The punching component 30 swings relative to the slide with the rotating shaft 36 as the center. The stopper 26 is mounted on the slide 28 of the first adjustment component, and the support plate 22 is arranged on the slide of the second adjustment component 31; the screw of the first adjustment component and the screw of the second adjustment component are both installed with a synchronous wheel 37, and the synchronous wheel is provided with a synchronous belt 38. When one screw is driven to rotate, the synchronous wheel rotates, and the other screw is synchronously rotated through the synchronous belt. The rotation of the screw causes the slide to move horizontally on the beam, thereby synchronously adjusting the positions of the punching component 30, the stopper 26 and the support plate 22. An upper baffle 23 for stripping is arranged above the support plate 22, and a second channel for the punching knife to pass through is opened on the upper baffle. When the punching knife retracts, the upper baffle 23 blocks the area around the punching position of the coil material, so that the punching knife 25 is effectively separated from the coil material 1, and the coil material is prevented from being taken away by the punching knife 25; the upper baffle 23 is mounted on the slide of the first adjustment component 31, and when the lateral position of the punching knife is adjusted, the upper baffle moves accordingly to adjust the lateral position.

[0048] The limiter 26 includes a buffer pad, which is installed on the frame through a mounting plate. The buffer pad has the functions of shock absorption and noise reduction, and reduces or avoids the rebound of the punching component, so that the punching component can quickly stay at the punching station. The coil 1 is conveyed forward, so after punching, it will swing forward with the punching knife 25. After the punching knife is separated from the coil, the punching knife swings backward. It is better to set the limiter 26 at the rear end of the punching component. When the punching component swings backward, the limiter blocks the punching component and makes it stop at the punching station. The reset of the punching component 30 can be reset by its own gravity, or by a reset elastic member. In the attached figure, the punching component is connected with a reset elastic member. The elastic force of the reset elastic member can reset the punching component more quickly. In addition, the reset elastic member has low cost, is easy to replace, and can adjust or rotate the elastic force of the elastic member according to needs. Depending on the installation position, the reset elastic member can be a spring or a tension spring. In the figure, the upper end of the punching component 30 is connected to the rotating shaft 36, and the reset elastic member is a tension spring 27. One end of the tension spring is connected to the lower end of the punching component 30, and the other end of the tension spring 27 is connected to a fixed position on the frame. If the punching component is swingably set on the slide 28, and the other end of the tension spring is connected to the slide, then when the coil drives the punching component to tilt, the tension spring 27 is stretched; when the punching knife 25 is separated from the coil 1, the tension of the tension spring 27 causes the punching component to quickly swing in the opposite direction and reset. The punching device also includes a sensor for detecting the position information of the coil, and the sensor and the power member are both connected to the controller. A color mark is printed on the coil. When the sensor detects the color mark, the information is sent to the controller, and the controller sends an instruction to the power member, and the power member drives the punching knife to perform the punching operation, so as to accurately punch the position.
