[0002] Granular and powdery products in the food, building materials, chemical and other industries are mainly packaged by filling. The packaging bags of this type of packaging must have both sealing and exhaust functions. The sealing of the packaging bag is to achieve moisture-proof and leak-proof effects; the exhaust is to discharge the gas in the bag after filling, so as to facilitate the stacking, transportation and sales of the filled packaging bags. If there is gas inside, it is not conducive to the stacking and transportation of the product, and the packaging bag is very likely to rupture under pressure.

[0047] The following describes the details and working principle of the embodiments and examples of the present invention in conjunction with the accompanying drawings. According to whether the exhaust bag needs auxiliary materials, it is divided into overlapping exhaust bags and auxiliary material air-infusing exhaust bags. Figure 1 , Figure 2 , Figure 4 , Figure 6 The exhaust holes 21 of the overlapped exhaust bag are directly processed on the main material 15. The two sides of the main material overlap up and down. The inner layer and outer layer of the overlapped part 29 of the main material have two longitudinal sealing lines 23. The exhaust cavity 28 is between the two longitudinal sealing lines 23. The exhaust holes 21 are arranged in the inner layer 27 of the overlapped part of the main material. The gas in the bag enters the exhaust cavity 28 through the exhaust holes 21 in the inner layer of the overlapped part of the main material, and then is discharged out of the bag. Figure 3 and Figure 5 The exhaust holes of the auxiliary material air-replenishing and exhausting bag are processed on the auxiliary material 16. The auxiliary material 16 and the main material 15 have two longitudinal sealing lines 23, and the exhaust cavity 28 is between the two longitudinal sealing lines. The gas in the bag body enters the exhaust cavity through the exhaust holes 21 on the auxiliary material and is then discharged out of the bag body.

[0048] Exhaust bags are also divided into microporous exhaust bags and flow channel exhaust bags, see Figure 2 , Figure 4 , Figure 6 The exhaust ports 22 of the microporous exhaust bag are arranged at both ends of the bag body or at one end of the bag body, and the gas in the bag body enters the exhaust cavity 28 through the exhaust holes and is then discharged from the exhaust ports 22 at both ends of the bag body. Figure 1 , Figure 3 , Figure 5 The exhaust port 22 of the flow channel exhaust bag is set on the bag surface and can also be set at both ends of the bag body or one end of the bag body. The exhaust cavity 28 forms a plurality of exhaust channels 25 through the flow channel sealing line. The positions of the exhaust hole 21 and the exhaust port are staggered. The gas in the bag body enters the exhaust channel 25 through the exhaust hole, and is finally discharged from the exhaust port 22 along the exhaust channel.

[0049] According to the type of main material of the exhaust bag, it can be divided into single-layer exhaust bag, peelable exhaust bag or double-layer exhaust bag. Figure 1 , Figure 2 , Figure 3 , the single-layer exhaust bag is the main material 15 is a single layer. Figure 4 and Figure 5 The peelable exhaust bag has a peelable outer film 18 and an inner main material 17. The peelable outer film can protect the inner main material, keeping it intact, clean and hygienic. It is often used in food packaging. Before the material is stored or processed, the peelable outer film of the bag is peeled off to keep the clean and hygienic inner main material. Figure 6 The double-layer exhaust bag comprises an inner layer main material 17 and an outer layer main material 19, and the double-layer exhaust bag provides double-layer protection for the material in the bag body.

[0050] The exhaust bag processing equipment includes a material unwinding rack, an exhaust processing mechanism and a bag blank forming mechanism. Both the main material and the auxiliary material are continuous coils, and the coils are wound on the tube core to form a material roll. The material unwinding rack is used to place the material rolls. If the auxiliary material air-inflation and exhaust bag is processed, the material unwinding rack includes the main material rack and the auxiliary material rack 12. If the double-layer exhaust bag is processed, the material unwinding rack includes the inner layer main material rack 1 and the outer layer main material rack 3. The exhaust processing mechanism includes a main material exhaust hole processing device and / or an auxiliary material exhaust hole processing device 13. If the double-layer exhaust bag is processed, and the exhaust holes are processed for both the inner layer main material and the outer layer main material, the main material exhaust hole processing device is provided with at least two groups, including an outer layer main material exhaust hole processing device 4 and an inner layer main material exhaust hole processing device 2. The bag blank forming mechanism includes a forming template 8 and a sealing device 9. The roll is a bag blank after being rolled into a tube, and the bag blank is also a material roll after being rolled up. The sealing device is used for longitudinal sealing during bag blank forming, longitudinal sealing during exhaust cavity forming, and flow channel sealing line for forming exhaust channel, and can also be used for longitudinal sealing of peelable outer film of peelable exhaust bag. If the auxiliary material patch exhaust bag is processed, an additional composite mechanism 6 is provided between the bag blank forming mechanism and the exhaust processing mechanism. Before the bag blank is formed, the auxiliary material and the main material are formed into two longitudinal sealing lines 23 through the additional composite mechanism, and the exhaust cavity 28 is between the two longitudinal sealing lines. The auxiliary material exhaust hole is between the two longitudinal sealing lines. Moreover, the additional composite mechanism can also process a number of flow channel sealing lines 24 between the two longitudinal sealing lines. If a double-layer exhaust bag is processed, the inner layer main material 17 and the outer layer main material 19 are formed into inner and outer layer film sealing lines 34 through the additional composite mechanism, and the two enter the bag blank forming mechanism together to avoid relative sliding between the two. The sealing device and the additional composite mechanism can be heat-sealed, ultrasonic welded, and glued composite. If the two layers of material forming the exhaust cavity are bonded together, the gas in the bag body cannot enter the exhaust cavity. In order to prevent the exhaust cavity from closing, the main material or the auxiliary material processed with the exhaust hole is passed through the anti-bonding processing mechanism 5 to form an anti-bonding bulge, which separates the inner layer and the outer layer of the overlapping part to prevent the two layers from bonding.

[0051] Attached Figure 7 In the invention, the exhaust bag processing equipment includes an inner main material rack 1, an outer main material rack 3, an inner exhaust hole processing device 2, an outer exhaust hole processing device 4, an anti-sticking processing mechanism 5 on the main rack, an additional composite mechanism 6, a heating mechanism 7, a bag blank forming mechanism, a winding mechanism 11, and also includes an auxiliary material rack 12, an auxiliary material exhaust hole processing device 13, and an anti-sticking processing mechanism 14 on the auxiliary rack. Users can select according to the needs of processing the bag body, so that the main material or auxiliary material passes through the station to be processed, and the station that does not need to be processed can be bypassed or the station can stop working. The following is an explanation through multiple preferred embodiments.

[0052] Embodiment 1, see attached Figure 1, processing overlapping flow channel single-layer exhaust bag, the exhaust port 22 is on the bag surface. This exhaust bag processing equipment includes a main material rack, a main material exhaust hole processing device, an anti-sticking processing mechanism and a bag blank forming mechanism. The main material 15 passes through the main material exhaust hole processing device, and the main material exhaust hole processing device processes the inner layer 27 of the main material overlap part between the two longitudinal sealing lines 23 with an inner layer main material exhaust hole 21, and processes the outer layer main material exhaust hole on the outer layer 26 of the main material overlap part between the two longitudinal sealing lines. The outer layer main material exhaust hole is the exhaust port 22, and the inner layer main material exhaust hole 21 and the outer layer main material exhaust hole are within the sealing lines 31 at both ends of the exhaust bag, and the sealing lines 31 at both ends of the exhaust bag are the sealing lines of the bag mouth and the bag bottom. Then the main material 15 passes through the anti-sticking processing mechanism, and the anti-sticking processing mechanism forms an anti-sticking protrusion 30 on the inner layer 27 of the main material overlap part or the outer layer 26 of the main material overlap part, and the protrusion faces the exhaust cavity 28. Before entering the bag blank forming process, the main material can be preheated, especially the main material with high thickness and hardness, which can be softened by preheating to facilitate folding and forming. The preheating can be carried out by a heating mechanism 7 such as an oven or a heating plate; the main material 15 enters from the bottom of the forming template of the bag blank forming mechanism, and the two sides of the main material are respectively extended along the two sides of the forming template, folded upward and covered on the top of the forming template, and the two sides of the main material covered on the top of the forming template overlap up and down, so that the main material is formed into a bag blank through the forming template, and the inner layer and outer layer of the overlapping part 29 of the main material are formed by the sealing device. Two longitudinal sealing lines 23 and a plurality of flow channel sealing lines 24 are formed, the flow channel sealing line is between the two longitudinal sealing lines and is not connected, an exhaust channel 25 is formed between the flow channel sealing line and the longitudinal sealing line and the flow channel sealing line, the exhaust holes of the outer layer main material are staggered with the exhaust holes 21 of the inner layer main material, that is, the exhaust cavity 28 forms a plurality of interconnected exhaust channels 25 through the flow channel sealing line, the exhaust holes of the outer layer main material are staggered with the exhaust holes 21 of the inner layer main material through the flow channel sealing line, and the exhaust holes of the inner layer main material are communicated with the exhaust holes of the outer layer main material through the exhaust channels 25. If the exhaust holes of the outer layer main material are opposite to the exhaust holes of the inner layer main material in vertical relation, the gas exhausted from the exhaust holes of the inner layer main material will be directly discharged from the exhaust holes of the outer layer main material, and the material with smaller particles will be discharged from the bag body along with the airflow. Therefore, the positions of the exhaust holes of the inner layer main material and the exhaust holes of the outer layer main material are staggered so that the exhaust holes of the inner layer main material are discharged from the exhaust holes of the outer layer main material through the exhaust channels 25. The number of the flow channel sealing lines 24 and the exhaust channels 25 formed can be set according to the requirements, and are not limited to the attached drawings of the present application. Figure 1 , 3 5. The formed bag blank can be finally cooled and rolled up, and the rolled bag blank can be used for product packaging later. On the packaging equipment, the sealing and cutting components perform transverse sealing and cutting on the bag blank, that is, forming the sealing lines 31 at both ends of the exhaust bag. The transverse sealing and cutting can seal the bottom and the bag mouth at the same time, which is usually performed after filling, which belongs to the conventional technical means of packaging equipment.

[0053] Embodiment 2, see attached Figure 2, processing overlapping microporous single-layer exhaust bags, the exhaust ports 22 are at both ends of the exhaust bag, and the exhaust ports are connected to the exhaust cavity, and the exhaust ports are arranged between the two longitudinal sealing lines 23 of the main material overlap part 29. This exhaust bag processing equipment includes a main material rack, a main material exhaust hole processing device, an anti-sticking processing mechanism and a bag blank forming mechanism. The main material 15 is processed with an inner layer main material exhaust hole 21 in the inner layer 27 of the main material overlap part between the two longitudinal sealing lines by the main material exhaust hole processing device, and the inner layer main material exhaust hole is within the sealing lines 31 at both ends of the exhaust bag. Then the main material is formed into an anti-sticking protrusion 30 in the inner layer 27 of the main material overlap part by the anti-sticking processing mechanism, and the protrusion faces the exhaust cavity. The main material is formed into a bag blank by a forming template, and the two sides of the main material overlap up and down, and the inner layer and outer layer of the main material overlap part 29 are formed into two longitudinal sealing lines 23 by the sealing device, and the exhaust cavity 28 is between the two longitudinal sealing lines, and finally cooled and rolled. The sealing lines 31 at both ends of the exhaust bag corresponding to the exhaust port 22 are treated with varnish. After the main material is treated with varnish, when the bag mouth or bag bottom is sealed on the packaging equipment, the bag mouth and bag bottom are sealed, but the varnish-treated part is not sealed, thereby forming an exhaust port, and the gas in the bag enters the exhaust cavity from the exhaust hole, and then is discharged from the exhaust port at both ends of the exhaust cavity. Usually, the main material 15 is treated with varnish during printing, and the position of the varnish treatment is accurate, so the material roll is printed and treated with varnish.

[0054] Embodiment 3, see attached Figure 3, processing auxiliary material patch-type flow channel single-layer exhaust bag, the exhaust port 22 is at both ends of the exhaust bag, and the exhaust port is communicated with the exhaust cavity, and the exhaust port is set between the two longitudinal sealing lines 23 of the overlapping part of the main material and the auxiliary material. This exhaust bag processing equipment includes a main material rack, an auxiliary material rack, an auxiliary material exhaust hole processing device, an anti-sticking processing mechanism, an additional composite mechanism and a bag blank forming mechanism. The material roll has a main material 15 and an auxiliary material 16. The frame is divided into a main material frame and an auxiliary material frame. The anti-sticking processing is used for the auxiliary material, so the auxiliary frame is provided with an auxiliary material exhaust hole processing device and an anti-sticking processing mechanism, and the additional composite mechanism is arranged on the main frame. The auxiliary material is processed with an auxiliary material exhaust hole 21 by the auxiliary material exhaust hole processing device, and the auxiliary material exhaust hole is within the sealing lines 31 at both ends of the exhaust bag. Then, the auxiliary material is processed by an anti-sticking processing mechanism to form an anti-sticking protrusion 30 on the auxiliary material, and the protrusion faces the exhaust cavity; then, the auxiliary material 16 and the main material 15 are formed into two longitudinal sealing lines 23 and a plurality of flow channel sealing lines 24 through an additional compounding mechanism. The auxiliary material is in the exhaust bag, and the exhaust cavity 28 is between the two longitudinal sealing lines. An exhaust channel 25 is formed between the flow channel sealing line and the longitudinal sealing line and between the flow channel sealing lines. The auxiliary material exhaust hole 21 is between the two longitudinal sealing lines 23, and the auxiliary material exhaust hole and the exhaust port 22 are staggered; similarly, the sealing lines at both ends of the exhaust bag corresponding to the exhaust port are treated with varnish; the main material compounded with the auxiliary material is formed into a bag blank by a forming template, and the two sides of the main material are longitudinally sealed by a sealing device. The two sides of the main material can be sealed by overlapping up and down or by left and right relative sealing. The two sides of the main material in the figure are overlapped up and down, and the inner and outer layers of the overlapping part 29 of the main material are longitudinally sealed by a sealing device, and finally cooled and rolled.

[0055] Embodiment 4, see attached Figure 4, processing overlapping microporous peelable exhaust bag, exhaust port 22 is at both ends of the exhaust bag, the exhaust port is communicated with the exhaust cavity 28, and the exhaust port is set between the two longitudinal sealing lines 23 of the main material overlap part 29. The main material of the peelable exhaust bag includes a peelable outer layer film 18 and an inner layer main material 17, where the main material overlap part refers to the inner layer main material overlap part, and the inner layer and outer layer overlap parts of the peelable outer layer film are the peelable outer layer film overlap part. The peelable outer layer film 18 and the inner layer main material 17 are compounded together and the overlap parts of the two sides of the peelable outer layer film and the inner layer main material are transversely misaligned, which means that one side of the peelable outer layer film 18 does not cover one side of the inner layer main material, and the other side of the peelable outer layer film extends to the outside of the other side of the inner layer main material, and the part of the inner layer main material not covered with the peelable outer layer film is the inner layer 27 of the main material overlap part. The exhaust bag processing equipment includes a main material rack, a main material exhaust hole processing device and a bag blank forming mechanism. The main material is processed with an inner layer main material exhaust hole 21 in the inner layer 27 of the main material overlap part between two longitudinal sealing lines 23 by the main material exhaust hole processing device. The main material 15 is formed into a bag blank by a forming template, and the two sides of the main material overlap up and down. Because the peelable outer layer film 18 and the overlapping parts of the two sides of the inner main material 17 are horizontally misaligned, it includes the overlapping of the inner layer main material and the overlapping of the peelable outer layer film. The inner layer 27 of the main material overlap part is not covered with the peelable outer layer film, and the other side of the peelable outer layer film should cover the outer layer 26 of the main material overlap part.

Similarly, the material roll of the peelable exhaust bag includes a peelable outer layer film 18 and an inner layer main material 17, the two are compounded together, and the overlapping parts of the two sides of the peelable outer layer film and the inner layer main material are transversely misaligned. This exhaust bag processing equipment includes a main material rack, an auxiliary material rack, an auxiliary material exhaust hole processing device, an anti-sticking processing mechanism, an additional compounding mechanism and a bag blank forming mechanism. The auxiliary material is processed with an auxiliary material exhaust hole 21 by the auxiliary material exhaust hole processing device, and the auxiliary material exhaust hole is within the sealing lines 31 at both ends of the exhaust bag. Then the auxiliary material is processed by the anti-sticking processing mechanism to form an anti-sticking protrusion 30 on the auxiliary material, and the protrusion faces the exhaust cavity 28. Then, the auxiliary material 16 and the main material 15 (including the peelable outer film 18 and the inner main material 17) are formed into two longitudinal sealing lines 23 and a plurality of flow channel sealing lines 24 through an additional composite mechanism. The auxiliary material is in the exhaust bag, and an exhaust cavity 28 is formed between the two longitudinal sealing lines. An exhaust channel 25 is formed between the flow channel sealing line and the longitudinal sealing line and between the flow channel sealing lines. The auxiliary material exhaust hole is between the two longitudinal sealing lines, and the auxiliary material exhaust hole 21 is staggered with the exhaust port 22.

The main material compounded with the auxiliary material is formed into a bag blank by a forming template, and the two side edges of the main material are overlapped up and down. The inner layer and the outer layer of the overlapping part 29 of the main material are sealed by a sealing device to form an inner layer main material longitudinal sealing line 33.

[0057] Embodiment 6, see attached Figure 6, processing overlapping microporous double-layer exhaust bags, the exhaust ports 22 are at both ends or one end of the exhaust bag, and the exhaust ports are connected to the exhaust cavity 28, and the exhaust ports are arranged between the two longitudinal sealing lines 23 of the main material overlapping part 29. The double-layer exhaust bag includes an inner layer main material 17 and an outer layer main material 19. The main material overlapping part here refers to the inner layer main material overlapping part, and the outer layer of the outer layer main material and the inner layer overlapping part are the outer layer main material overlapping part. This exhaust bag processing equipment includes an inner layer main material rack, an outer layer main material rack, a main material exhaust hole processing device, an anti-sticking processing mechanism, an additional composite mechanism and a bag blank forming mechanism. The inner layer main material 17 is processed with the inner layer main material exhaust hole 21 by the main material exhaust hole processing device; then the inner layer main material passes through the anti-sticking processing mechanism, and the anti-sticking processing mechanism forms an anti-sticking protrusion 30 on the inner layer main material, and the protrusion faces the exhaust cavity 28. Then the inner layer main material 17 and the outer layer main material 19 enter the additional composite mechanism together, and the inner and outer layer film sealing lines 34 are formed by the additional composite mechanism to prevent the two from moving horizontally. At this time, the overlapping parts of the two sides of the inner layer main material and the outer layer main material are horizontally misaligned, which means that one side of the outer layer main material 19 does not cover one side of the inner layer main material, and the other side of the outer layer main material extends to the other side of the inner layer main material for longitudinal sealing. Then the two enter the bag blank forming mechanism together, and the bag blank is formed by the forming template tube, and the two sides of the main material overlap up and down, including the overlapping of the inner layer main material and the overlapping of the outer layer main material. The inner layer 27 of the overlapping part of the main material is not covered with the outer layer main material 19, and one side of the outer layer main material should cover the outer layer 26 of the overlapping part. The outer layer and the inner layer of the overlapping part of the main material are formed into two longitudinal sealing lines 23 by the sealing device, and the exhaust cavity 28 is between the two longitudinal sealing lines. The sealing lines at both ends of the exhaust bag corresponding to the exhaust port 22 are treated with varnish. One side of the outer layer main material 19 covers the main material overlapping part 29 and the other side of the outer layer main material, and the outer layer and the inner layer of the outer layer main material overlapping part form an outer layer longitudinal sealing line 35, that is, the inner layer main material is sealed with the inner layer main material, and the outer layer main material is sealed with the outer layer main material.

[0058] The sealing device preferably adopts gluing and compounding, including a gluing structure and a compounding structure; the additional compounding mechanism can use a glue spraying method to apply glue on the main material or the auxiliary material, and the two can be compounded by a guide roller.

[0059] Attached Figure 8 , 9, the gluing structure includes a glue extrusion component, a first detector 44 and a driving component for driving the glue extrusion component to move horizontally on the frame. The glue extrusion component includes an extrusion die 46, which is above the molding template and placed between the outer layer 41 and the inner layer 42 of the overlapping part of the coil. If one longitudinal sealing line is required, the extrusion die extrude one line of glue, and if three longitudinal sealing lines are required, the extrusion die extrude three lines of glue. If the exhaust bag body of Example 1 is processed, the extrusion die is between the inner layer and the outer layer of the overlapping part of the main material, and extrude two lines of glue to form two sealing lines 23; if the exhaust bag of Example 6 is processed, the extrusion die is between the inner layer and the outer layer of the overlapping part of the main material and between the inner layer and the outer layer of the overlapping part of the outer layer main material to form three sealing lines, which are two longitudinal sealing lines 23 of the inner layer main material and one longitudinal sealing line 35 of the outer layer. The first detector 44 moves laterally synchronously with the glue extrusion component. The first detector can be installed on the glue extrusion component. The first detector, the glue extrusion component and the driving component are all connected to the controller. The first detector collects the edge information of the outer layer of the overlapping part of the roll material and sends it to the controller, such as the edge of the peelable outer film 18 in Example 5 and the edge of the outer layer main material 19 in Example 6. The controller sends instructions to the driving component according to the received edge information of the outer layer of the overlapping part, and the controller controls the operation of the glue extrusion component. Specifically, the first detector 44 collects the edge information of the outer layer of the overlapping part of the roll material in real time, and accurately determines the gluing position of the roll material. The controller sends instructions to the driving component according to the information collected by the first detector. If the outer layer edge of the overlapping part of the roll material is detected to be offset to the left, the driving component drives the glue extrusion component to move to the left. If the outer layer edge of the overlapping part of the roll material is offset to the right, the driving component drives the glue extrusion component to move to the right, so that the glue extruded by the glue extrusion component is accurately coated, and the two bag surfaces are prevented from being bonded together due to the offset of the glue application.

[0060] The glue liquid extrusion component includes a barrel 47, an extrusion screw 48, an extrusion die 45 and a fourth motor driving the extrusion screw 48 to rotate. The extrusion screw is arranged in the barrel. A feed port is arranged at one end of the barrel. In order to facilitate feeding, a hopper 49 is installed at the feed port to add plastic granules into the hopper. A discharge port is arranged at the other end of the barrel 47. The discharge port is connected to the extrusion die 45, and the extrusion die 46 is connected to the extrusion die. The fourth motor drives the extrusion screw 48 to rotate. The rotation of the extrusion screw causes the material in the barrel to be extruded and transported to the discharge port. During the extrusion and transportation process, the material is extruded and melted. The material can also be heated in the barrel 47 to accelerate the melting speed of the material. The melted material becomes glue liquid and is extruded from the extrusion die. The glue liquid just extruded has good fluidity. The same sealing area uses less glue, the cost is lower, and the viscosity is better. The bonding is fast and firm, and there is no need to heat and shape the bag blank additionally.

[0061] The extrusion die nozzles 46 are provided in a plurality and are arranged longitudinally, and the plurality of extrusion die nozzles 46 are evenly arranged transversely; the extrusion die head 45 is flat and extends longitudinally, so that the height of the extrusion die head and the extrusion die nozzle is low, which is convenient for penetrating into the outer layer 41 and the inner layer 42 of the overlapping part of the coil material, and can quickly enter the sealing after the overlapping part is glued, thereby improving the sealing effect. The first detector 44 is a slot-type photoelectric eye, and the slot-type photoelectric eye has a groove 43 for the outer edge of the overlapping part of the coil material to enter, so that it is convenient to collect the edge information of the outer layer of the overlapping part, and the first detector collects the edge information of the outer layer of the overlapping part more accurately.

[0062] See 10-13, in which the X-axis is horizontal, also the left-right direction; the Y-axis is longitudinal, also the front-back direction; and the Z-axis is vertical, also the up-down direction. The composite structure includes a composite pressure roller 61, which is connected to the fifth motor 86, and the fifth motor drives the composite pressure roller to rotate. The composite pressure roller is rotatably mounted on the left side plate 62 and the right side plate 63. The left side plate and the right side plate are respectively vertically slidably arranged on the mounting plate 71 through the left guide rail and the right guide rail 82. The left guide rail and the right guide rail 82 are vertically arranged. In the figure, the left guide rail and the right guide rail are respectively mounted on the left side plate and the right side plate, and the mounting plate is provided with a left slide and a right slide respectively slidably arranged with the left guide rail and the right guide rail. The mounting plate 71 is provided with a first adjusting component for adjusting the height difference between the left side plate and the right side plate, and a driving component 70 for driving the left side plate and the right side plate to rise and fall. In the non-working state, the driving member drives the left plate and the right plate to move up along the left guide rail and the right guide rail respectively, that is, drives the composite pressure roller 61 to move up and away from the lower roller. When working, the driving member 70 drives the composite pressure roller to move down, and the composite pressure roller rotates and cooperates with the lower roller to pull and roll the coiled material so that the glued coiled material is compounded together. The first adjustment component adjusts the height difference between the left plate and the right plate, that is, adjusts the angle between the composite pressure roller and the horizontal plane and the lower roller. Usually, the lower roller is set horizontally. If the thickness of the coiled material sealing part is consistent, the composite pressure roller is parallel to the vertical direction of the lower roller. If the left side of the coiled material sealing part is thinner than the right side, the left side of the composite pressure roller is lower than the right side. If the right side of the coiled material sealing part is thinner than the left side, the right side of the composite pressure roller 61 is lower than the left side, so that the left and right thicknesses of the sealing part glue are consistent and moderate, and the coiled material is subjected to the same pressure, and the composited coiled material is flat and wrinkle-free.

[0063] The right side plate 63 is connected to the transverse plate 67, the driving member is connected to the transverse plate, the fifth motor 86 is installed on the right side plate 63, the left side plate 62 is connected to the mounting block 64, the mounting block is movably connected to the transverse plate, the driving member drives the transverse plate to rise and fall, which is equivalent to the driving member driving the left side plate and the right side plate to rise and fall, and at the same time, the spacing between the mounting block and the transverse plate can be adjusted by the first adjusting member. The first adjusting member includes an adjusting screw 68, a first spring 65 and a first bolt 66, the adjusting screw is rotatably mounted on the mounting plate and rises and falls relative to the mounting plate 71, the adjusting screw presses the transverse plate 67 and controls the height spacing between the transverse plate and the mounting block 64. In the figure, the upper end of the first bolt passes through the first spring 65 and the cross plate 67 in sequence and is threadedly connected to the mounting block 64. The first bolt connects the mounting block to the cross plate, and the elastic force of the first spring brings the mounting block and the cross plate closer to each other. The adjusting screw overcomes the elastic force of the first spring and presses the cross plate. The adjusting screw moves down to press the cross plate. Due to the limitation of the driving component, the left side plate 62 moves up relative to the right side plate 63, that is, the left end of the composite pressure roller 61 moves up. If the adjusting screw moves up, then under the action of the elastic force of the first spring, the distance between the mounting block and the cross plate becomes smaller, and the left side plate moves down relative to the right side plate, then the left end of the composite pressure roller moves down, so as to adjust the angle between the composite pressure roller and the horizontal plane and the lower roller. For the convenience of operation, the lower end of the adjusting screw passes through the mounting block to press the horizontal plate, the upper end of the adjusting screw is threadedly connected with a nut, the mounting plate is provided with a limiter 76 to limit the nut 77 from moving up and down, the circumferential surface of the nut is provided with a transmission tooth, the transmission tooth meshes with the worm 69, the adjusting screw 68 is arranged vertically, the upper end of the adjusting screw is too high, it is not convenient for the staff to operate, the worm is arranged horizontally for easier operation. The rotation of the worm drives the nut to rotate, and the rotation of the nut drives the adjusting screw to rise and fall, so that the relative height position of the left plate and the right plate can be adjusted.

[0064] The mounting plate 71 is rotatably mounted on the moving plate 72 via the rotating shaft 73, and the mounting plate is connected to a second adjusting component for adjusting its vertical angle. There is a tension difference between the upper and lower layers of the coil sealing portion. Usually, the tension of the lower layer is large, and the tension of the upper layer is small. The upper layer is relatively loose. If the composite pressure roller 61 is horizontally parallel to the lower roller, the upper layer will deviate during composite traction, such as the upper layer shifting to the outside. The present invention can rotate the mounting plate vertically relative to the moving plate through the second adjusting component, that is, the composite pressure roller swings forward or backward relative to the lower roller, and the force of the composite pressure roller on the upper layer is biased to the inside, offsetting the force of the upper layer shifting to the outside due to the small tension, so that the upper and lower layers of the sealing portion are aligned and in a correct position. The second adjustment component includes a second bolt 75 and a second spring 74. One end of the second bolt passes through the mounting plate 71 and the second spring in sequence and is threadedly connected to the movable plate 72. The second bolt 75 rotates forward to reduce the distance between the mounting plate and the right side of the movable plate, that is, the mounting plate rotates counterclockwise, and the left end of the composite pressure roller swings backward and the right end swings forward. Conversely, the second bolt 75 rotates in the reverse direction to reduce the distance between the mounting plate and the right side of the movable plate, and the left end of the composite pressure roller swings forward and the right end swings backward. The adjustment is convenient and quick. The mounting plate is provided with a first connecting arm 79, and the first connecting arm is connected to the rotating shaft 73; the movable plate 72 is provided with a second connecting arm 80, and the second connecting arm is rotatably arranged with the rotating shaft 73.

The eccentric wheel is connected to the output shaft of the second motor, one end of the connecting rod is rotatably connected to the eccentric wheel, and the other end of the connecting rod is rotatably connected to the swing block 104. The second motor drives the eccentric wheel to rotate, and the eccentric wheel pulls or pushes the swing block through the connecting rod to swing around the pivot. When the swing block swings toward the brush roller 94, the needle roller or blade on the rotating shaft is pressed against the brush roller; when the swing block swings in the opposite direction, the needle roller or blade on the rotating shaft moves away from the brush roller; the mechanical transmission is more stable and fast, making the processing of the exhaust hole more stable and accurate.

The rotating disk is provided with a plurality of groups, all of which are sleeved on the rotating shaft. An isolation plate 111 is provided between adjacent rotating disks, and the blades on adjacent rotating disks are mutually staggered, that is, the adjacent rotating disks are respectively the first rotating disk and the second rotating disk, and the blades on the first rotating disk are axially opposite to the gap on the second rotating disk. Similarly, the blades on the second rotating disk are axially opposite to the gap 117 on the first rotating disk, and the adjacent linear blade edges formed on the coil are also mutually staggered, and the linear blade edges are linear exhaust holes. The rotating disks are arranged transversely on the rotating shaft, and multiple transverse linear blade edges can be formed on the coil, and the adjacent linear blade edges are mutually staggered, thereby improving the flowability of the exhaust holes.

The second detector adopts a slot-type photoelectric eye and is arranged in front of the moving component, that is, the bag blank pulled forward passes through the slot-type photoelectric eye, and the slot-type photoelectric eye continuously collects edge information of the bag blank.

[0076] The moving component causes the bag blank to move back and forth laterally, and the range of the lateral reciprocating movement is controlled by the controller. For example, when the bag blank moves 6 cm laterally, when the second detector detects that the edge of the bag blank is offset to the left by 3 cm, the controller sends a command to the moving component to cause the bag blank to shift to the right. When the second detector detects that the edge of the bag blank is offset to the right by 3 cm, the controller sends a command to the moving component to cause the bag blank to shift to the left. This process is repeated to accurately control the range of the lateral movement of the bag blank. At the same time, due to the offset of the bag blank to the left and right, the bag blank on the reel is laterally misaligned. The adjacent inner and outer layers of the bag blanks are staggered laterally, and the parts with more layers are evenly spread laterally and will not be concentrated in one position. For example, the middle longitudinal seal is thicker with a width of 5 cm, and other parts are thinner. After transverse offset rolling, assuming the offset range is 6 cm, the middle longitudinal seal of the rolled bag blank roll 157 is laterally expanded to 11 cm, and the transverse thickness distribution is balanced, so it is not easy to collapse, and more quantity can be rolled at one time; and one side edge of the inner layer is covered by the outer layer. As the layers are wound, the side edge of the inner layer is compacted, the side creases are more stable, and the formed bag body is straighter.

[0077] The moving part includes a first moving seat 158 ​​and a fifth driving member for driving the first moving seat to move left and right or swing forward and backward. The first moving seat is rotatably provided with a first guide roller 152 and a second guide roller 153. The second guide roller is arranged in front of the first guide roller, and the bag blank bypasses the first guide roller and the second guide roller in sequence. When the first moving seat moves to the right or the first moving seat swings clockwise, the bag blank deviates to the right, and vice versa, the bag blank deviates to the left. It is better to swing the first moving seat to reduce the influence on the bag blank in the input direction. The first moving seat is slidably provided on the first guide rail 161 and the second guide rail 162. The first guide rail and the second guide rail are tilted on the machine base, and the first guide rail and the second guide rail are longitudinally symmetrically provided; the fifth driving member includes a seventh motor 163, a telescopic rod 160 and a second connecting rod 159. One end of the second connecting rod is rotatably connected to the telescopic rod, and the other end of the second connecting rod is connected to the first moving seat 158. The seventh motor 163 is connected to the telescopic rod 160 and drives the telescopic rod to extend and retract horizontally. The seventh motor drives the telescopic rod to extend and retract, and the telescopic rod drives the first movable seat to swing back and forth along the first guide rail and the second guide rail, so that the mechanical transmission is more stable. When the telescopic rod is retracted, the left end of the first movable seat 158 ​​moves upward along the first guide rail 161, and the right end moves downward along the second guide rail 162, and the first guide roller 152 and the second guide roller 153 swing clockwise, and the bag blank pulled forward deviates to the right accordingly; when the telescopic rod is extended, the first movable seat swings in the opposite direction along the first guide rail and the second guide rail, that is, the left end of the first movable seat moves downward along the first guide rail, and the right end moves upward along the second guide rail, and the first guide roller and the second guide roller tilt in the opposite direction, and the bag blank pulled forward deviates to the left accordingly, so that the rolled bag blank material roll is horizontally dislocated.
