Description

Technical Field

[0001] This utility model relates to an improved utility model of an exhaust bag processing equipment. Background Technology

[0002] Granular and powdered products in industries such as food, building materials, and chemicals are mainly packaged using filling methods. These packaging bags must have both sealing and venting functions. Sealing the packaging bag is to achieve moisture and leakage prevention; venting is to expel gas from the bag after filling, facilitating stacking, transportation, and sales. If gas remains inside, it is detrimental to product stacking and transportation, and the packaging bag is also prone to rupture under pressure.

[0003] Currently, some exhaust bags cannot be mass-produced due to their complex structure. Some exhaust bags can only be processed semi-automatically, such as processing the exhaust holes and forming the bag blank separately. Therefore, the production efficiency of existing exhaust bags is low and the cost is high. Utility Model Content

[0034] As a preferred option, if the overlapping exhaust bag is to be processed, the main material passes through the main material exhaust hole processing device and the bag blank forming mechanism in sequence. The main material is formed into a cylinder by the forming template and the two sides of the main material overlap. The inner and outer layers of the overlapping part of the main material are sealed by a sealing device to form two longitudinal sealing lines. The space between the two longitudinal sealing lines is an exhaust chamber. The main material exhaust hole processing device processes an inner layer main material exhaust hole in the inner layer of the overlapping part of the main material between the two longitudinal sealing lines.

[0035] If processing auxiliary material patch venting bags, the auxiliary material, after passing through the auxiliary material venting hole processing device, enters the bag blank forming mechanism together with the main material.

[0047] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. Based on whether the exhaust bag requires auxiliary materials, it is divided into overlapping exhaust bags and auxiliary material replenishment exhaust bags, see... Figure 1 , Figure 2 , Figure 4 , Figure 6 The vent 21 of the overlapping vent bag is directly machined onto the main material 15. The two sides of the main material overlap vertically. The inner and outer layers of the overlapping part 29 of the main material have two longitudinal sealing lines 23. The space between the two longitudinal sealing lines 23 is the vent chamber 28. The vent 21 is located in the inner layer 27 of the overlapping part of the main material. The gas inside the bag enters the vent chamber 28 through the vent 21 in the inner layer of the overlapping part of the main material, and then exits from the outside of the bag. See Figure 3 and Figure 5 The exhaust holes of the auxiliary material air supply and exhaust bag are processed on the auxiliary material 16. The auxiliary material 16 and the main material 15 have two longitudinal sealing lines 23. The space between the two longitudinal sealing lines is the exhaust chamber 28. The gas inside the bag enters the exhaust chamber through the exhaust hole 21 on the auxiliary material and then exits the bag.

[0048] Exhaust bags are further divided into microporous exhaust bags and channel exhaust bags, see Figure 2 , Figure 4 , Figure 6 The vent 22 of the microporous venting bag is located at both ends or one end of the bag body. Gas inside the bag enters the venting chamber 28 through the vent holes and then exits from the vent 22 at both ends of the bag body. See [link / reference]. Figure 1 , Figure 3 , Figure 5 The exhaust port 22 of the flow channel exhaust bag is located on the bag surface or at both ends of the bag body or one end of the bag body. The exhaust chamber 28 forms several exhaust channels 25 through the flow channel sealing line. 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 finally exits from the exhaust port 22 along the exhaust channel.

[0049] According to the type of main material of the venting bag, it is divided into single-layer venting bags, peelable venting bags, or double-layer venting bags. See Figure 1 , Figure 2 , Figure 3 The single-layer exhaust bag, i.e., the main material 15, is single-layer. See 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 protects the inner main material, keeping it intact, clean, and hygienic. It is commonly used in food packaging. Before the material is stored or processed, the peelable outer film is removed from the bag to preserve the clean and hygienic inner main material. See [link to product description]. Figure 6 The double-layer exhaust bag has an inner main material 17 and an outer main material 19, providing double protection for the material in the bag.

[0050] The venting bag processing equipment includes a feeding rack, a venting processing mechanism, and a bag blank forming mechanism. Both the main material and auxiliary material are continuous rolls, wound onto a core tube to form a material roll. The feeding rack is used to hold the material rolls. If processing auxiliary material-filled venting bags, the feeding rack includes a main material rack and an auxiliary material rack 12. If processing double-layer venting bags, the feeding rack includes an inner main material rack 1 and an outer main material rack 3. The venting processing mechanism includes a main material vent hole processing device and / or an auxiliary material vent hole processing device 13. If processing double-layer venting bags, and both the inner and outer main materials require vent holes, then at least two sets of main material vent hole processing devices are provided, including an outer main material vent hole processing device 4 and an inner main material vent hole processing device 2. The bag blank forming mechanism includes a forming template 8 and a sealing device 9. The rolled material forms a bag blank, and the bag blank is also wound into a material roll. The sealing device is used for longitudinal sealing during bag preform forming, longitudinal sealing during venting cavity forming, and flow channel sealing lines for forming venting channels. It can also be used for longitudinal sealing of the peelable outer film of peelable vent bags. If processing auxiliary material patch vent bags, an additional composite mechanism 6 is provided between the bag preform forming mechanism and the venting processing mechanism. Before bag preform forming, the auxiliary material and main material form two longitudinal sealing lines 23 through the additional composite mechanism, with a venting cavity 28 between the two longitudinal sealing lines. The auxiliary material venting hole is located between the two longitudinal sealing lines. Furthermore, the additional composite mechanism can also process several flow channel sealing lines 24 between the two longitudinal sealing lines. If processing double-layer vent bags, the inner main material 17 and the outer main material 19 form inner and outer layer film sealing lines 34 through the additional composite mechanism, and both enter the bag preform forming mechanism together to prevent relative sliding. The sealing device and the additional composite mechanism can employ heat sealing, ultrasonic welding, and adhesive bonding, etc. If the two layers of material forming the venting cavity are bonded together, the gas inside the bag cannot enter the venting cavity. To prevent the venting cavity from closing, the main material or auxiliary material with venting holes is processed by the anti-bonding processing mechanism 5 to form anti-bonding protrusions. The protrusions separate the inner and outer layers of the overlapping part, preventing the two layers from bonding together.

[0051] Appendix Figure 7The venting bag processing equipment includes an inner main material rack 1, an outer main material rack 3, an inner venting hole processing device 2, an outer venting hole processing device 4, an anti-adhesion processing mechanism 5 on the main frame, an additional composite mechanism 6, a heating mechanism 7, a bag blank forming mechanism, and a winding mechanism 11. It also includes a secondary material rack 12, a secondary material venting hole processing device 13, and an anti-adhesion processing mechanism 14 on the secondary frame. Users select the appropriate equipment based on the bag processing requirements, allowing the main or secondary material to pass through the required processing stations, bypassing or stopping at stations where no processing is needed. Several preferred embodiments are described below.

[0052] Example 1, see appendix Figure 1The equipment for processing single-layer vented bags with overlapping flow channels includes a main material rack, a main material venting hole processing device, an anti-adhesion processing mechanism, and a bag blank forming mechanism. The main material 15 passes through the main material venting hole processing device, which processes inner main material venting holes 21 on the inner layer 27 of the main material overlap between two longitudinal sealing lines 23, and outer main material venting holes on the outer layer 26 of the main material overlap between the two longitudinal sealing lines. These outer main material venting holes are the venting holes 22. The inner and outer main material venting holes 21 and 22 are located within the sealing lines 31 at both ends of the vented bag, which are the sealing lines at the bag opening and bottom. Next, the main material 15 passes through the anti-adhesion processing mechanism, which forms anti-adhesion protrusions 30 on the inner layer 27 or outer layer 26 of the main material overlap, with the protrusions facing the venting chamber 28. Before entering the bag blank forming process, the main material can be preheated, especially for thick and hard materials. Preheating softens the material, making it easier to fold and form. Preheating can be achieved using a heating mechanism such as an oven or a heating plate. The main material 15 enters from below the forming template of the bag blank forming mechanism. Both sides of the main material are folded upwards along the two sides of the forming template and placed on top of the forming template. The two sides of the main material placed on top of the forming template overlap vertically. In this way, the main material is formed into a bag blank through the forming template. The inner and outer layers of the overlapping part 29 of the main material are then sealed by a sealing device. Two longitudinal sealing lines 23 and several flow channel sealing lines 24 are formed. The flow channel sealing lines are between the two longitudinal sealing lines and are not connected. The flow channel sealing lines form exhaust channels 25 with the longitudinal sealing lines and the flow channel sealing lines. The exhaust holes of the outer main material and the exhaust holes of the inner main material are staggered. That is, the exhaust chamber 28 forms several interconnected exhaust channels 25 through the flow channel sealing lines. The exhaust holes of the outer main material and the exhaust holes of the inner main material are staggered through the flow channel sealing lines. The exhaust holes of the inner main material are connected to the exhaust holes of the outer main material through the exhaust channels 25. If the outer main material vent and the inner main material vent are vertically aligned, the gas discharged from the inner main material vent will directly exit from the outer main material vent, and smaller particles will be discharged out of the bag with the airflow. Therefore, the positions of the inner and outer main material vents are staggered, so that the gas from the inner main material vent exits through the vent channel 25 and then exits from the outer main material vent. The number of flow channel sealing lines 24 and the formed vent channels 25 can be set according to requirements and are not limited to those specified in this application. Figure 1 , 3 The method provided in section 5. After the bag blank is formed, it can be cooled and rolled up. The rolled bag blank can be used for product packaging. On the packaging equipment, the sealing and cutting part performs a transverse sealing cut on the bag blank, which forms the sealing lines 31 at both ends of the vent bag. The transverse sealing cut can seal the bottom and the bag mouth at the same time. It is usually done after filling. This is a conventional technical means of packaging equipment.

[0053] Example 2, see appendix Figure 2This equipment processes overlapping microporous single-layer vented bags. Vents 22 are located at both ends of the vented bag and communicate with the venting chamber. The vents are positioned between the two longitudinal sealing lines 23 of the main material overlap section 29. The vented bag processing equipment includes a main material frame, a main material vent hole processing device, an anti-adhesion processing mechanism, and a bag blank forming mechanism. The main material 15 is processed with inner-layer main material vent holes 21 in the inner layer 27 of the main material overlap section between the two longitudinal sealing lines by the main material vent hole processing device. The inner-layer main material vent holes are located within the sealing lines 31 at both ends of the vented bag. Next, the main material undergoes anti-adhesion processing to form anti-adhesion protrusions 30 in the inner layer 27 of the main material overlap section, with the protrusions facing the venting chamber. The main material is formed into a bag blank by a forming template, with the two sides of the main material overlapping vertically. The inner and outer layers of the main material overlap section 29 are sealed by a sealing device to form two longitudinal sealing lines 23, with the venting chamber 28 located between the two longitudinal sealing lines. Finally, the bag is cooled and rolled up. The sealing lines 31 at both ends of the vent 22 corresponding to the venting port are coated with varnish. After the main material is coated with varnish, when the bag opening or bottom is sealed on the packaging equipment, the bag opening and bottom are sealed, but the varnished area is not sealed, thus forming a vent. The gas inside the bag enters the venting chamber through the vent hole and then exits from the venting port at both ends. Usually, the main material 15 is coated with varnish during printing, and the varnishing position is precise. Therefore, the material roll has undergone both printing and varnishing treatment.

[0054] Example 3, see appendix Figure 3This equipment processes single-layer vented bags with a patch-type flow channel for auxiliary materials. Vents 22 are located at both ends of the vented bag and communicate with the venting chamber. The vents are positioned between the two longitudinal sealing lines 23 of the overlapping portion of the main material and auxiliary material. This vented bag processing equipment includes a main material frame, an auxiliary material frame, an auxiliary material venting hole processing device, an anti-adhesion processing mechanism, an additional composite mechanism, and a bag blank forming mechanism. The material roll contains main material 15 and auxiliary material 16. The frame is divided into a main material frame and an auxiliary material frame. Anti-adhesion processing is used for the auxiliary material; therefore, the auxiliary frame is equipped with an auxiliary material venting hole processing device and an anti-adhesion processing mechanism. The additional composite mechanism is located on the main frame. The auxiliary material is processed with auxiliary material venting holes 21 by the auxiliary material venting hole processing device. The auxiliary material venting holes are located within the sealing lines 31 at both ends of the vented bag. Next, the auxiliary material is processed by an anti-adhesion processing mechanism to form anti-adhesion protrusions 30 on the auxiliary material, with the protrusions facing the exhaust cavity; then, the auxiliary material 16 and the main material 15 are processed by an additional composite mechanism to form two longitudinal sealing lines 23 and several flow channel sealing lines 24. The auxiliary material is inside the exhaust bag, and the space between the two longitudinal sealing lines is the exhaust cavity 28. The flow channel sealing lines and the longitudinal sealing lines and the flow channel sealing lines form an exhaust channel 25. 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 with the auxiliary material is formed into a bag blank by forming a forming template. 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 vertically or by left and right opposite sealing. In the figure, the two sides of the main material are sealed by overlapping vertically. 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 up.

[0055] Example 4, see appendix Figure 4The fabricated lap-type microporous peelable vent bag has vents 22 at both ends, which communicate with the vent chamber 28. The vents are positioned between the two longitudinal sealing lines 23 of the main material overlap 29. The main material of the peelable vent bag includes a peelable outer film 18 and an inner main material 17. Here, the main material overlap refers to the inner main material overlap, and the inner and outer overlaps of the peelable outer film are the peelable outer film overlap. The peelable outer film 18 and the inner main material 17 are combined together, and the two sides of the peelable outer film and the inner main material overlap are laterally misaligned. This means that one side of the peelable outer film 18 does not cover one side of the inner main material, while the other side of the peelable outer film extends beyond the other side of the inner main material. The part of the inner main material not covered by the peelable outer film is the inner layer 27 of the main material overlap. This type of venting bag processing equipment includes a main material rack, a main material venting hole processing device, and a bag blank forming mechanism. The main material venting hole processing device processes inner main material venting holes 21 in the inner layer 27 of the main material overlap between two longitudinal sealing lines 23. The main material 15 is formed into a bag blank by forming a tube through a forming template, and the two sides of the main material overlap vertically. Because the peelable outer film 18 and the two sides of the inner main material 17 are laterally misaligned, it includes inner main material overlap and peelable outer film overlap. The inner layer 27 of the main material overlap is not covered with peelable outer film, while the other side of the peelable outer film must cover the outer layer 26 of the main material overlap. The outer and inner layers of the main material overlap 29 are sealed by a sealing device to form two longitudinal sealing lines 23. The space between the two longitudinal sealing lines is a venting chamber 28. The sealing lines at both ends of the venting bag corresponding to the venting port 22 are treated with a clear varnish. One side of the peelable outer film 18 covers the main material overlap 29 and the other side of the peelable outer film. The outer and inner layers of the peelable outer film overlap form a longitudinal sealing line 32 of the outer film. That is to say, the inner main material is sealed with the inner main material, and the peelable outer film is sealed with the peelable outer film. This will not hinder the peeling of the peelable outer film, and even if the peelable outer film is sealed, it can still be peeled off under the action of external force.

[0056] Example 5, see appendix Figure 5 and 7The processing equipment for this type of vented bag includes a peelable outer film 18 and an inner main material 17, which are bonded together and laterally misaligned on both sides. The venting device processes the venting holes 21 on the secondary material, which are located within the sealing lines 31 at both ends of the vented bag. Then, the anti-adhesion processing mechanism forms anti-adhesion protrusions 30 on the secondary material, facing the venting chamber 28. Then, the auxiliary material 16 and the main material 15 (including the peelable outer film 18 and the inner main material 17) are combined by an additional composite mechanism to form two longitudinal sealing lines 23 and several flow channel sealing lines 24. The auxiliary material is inside the exhaust bag, and the space between the two longitudinal sealing lines is an exhaust chamber 28. The flow channel sealing lines and the longitudinal sealing lines and the space between the flow channel sealing lines form an exhaust channel 25. The exhaust hole of the auxiliary material is between the two longitudinal sealing lines, and the exhaust hole 21 of the auxiliary material is staggered from the exhaust port 22. The sealing lines at both ends of the exhaust bag corresponding to the exhaust port are treated with varnish. The main material with composite auxiliary materials is formed into a bag blank by forming a tube through a forming template. The two sides of the main material overlap vertically. The inner and outer layers of the main material overlap 29 are sealed by a sealing device to form a longitudinal sealing line 33 of the inner main material. One side of the peelable outer film covers the main material overlap 29 and the other side of the peelable outer film. The outer and inner layers of the peelable outer film overlap are sealed by a sealing device to form a longitudinal sealing line 32 of the outer film.

[0057] Example 6, see appendix Figure 6The equipment for processing double-layer microporous vent bags includes an inner main material 17 and an outer main material 19. The vent outlet 22 is located at one or both ends of the vent bag and communicates with the vent cavity 28. The vent outlet is positioned between the two longitudinal sealing lines 23 of the main material overlap 29. The double-layer vent bag includes an inner main material 17 and an outer main material 19. Here, the main material overlap refers to the inner main material overlap, and the outer layer overlap of the outer main material with the inner layer overlaps is the outer main material overlap. This vent bag processing equipment includes an inner main material frame, an outer main material frame, a main material vent hole processing device, an anti-adhesion processing mechanism, an additional composite mechanism, and a bag blank forming mechanism. The inner main material 17 is processed with inner main material vent holes 21 by the main material vent hole processing device; then, the inner main material passes through the anti-adhesion processing mechanism, which forms anti-adhesion protrusions 30 on the inner main material, with the protrusions facing the vent cavity 28. Next, the inner main material 17 and the outer main material 19 enter the additional composite mechanism together, forming an inner and outer film sealing line 34 to prevent them from moving laterally. At this time, the overlapping parts of the inner and outer main materials are laterally misaligned, meaning that one side of the outer main material 19 does not cover one side of the inner main material, while the other side of the outer main material extends beyond the other side of the inner main material for longitudinal sealing. Then, they enter the bag blank forming mechanism together, forming a bag blank through the forming template, with the two sides of the main material overlapping vertically, including the inner and outer main material overlaps. The inner layer 27 of the main material overlap does not cover the outer main material 19, while one side of the outer main material covers the outer layer 26 of the main material overlap. The outer and inner layers of the main material overlap are then sealed by a sealing device to form two longitudinal sealing lines 23. Between the two longitudinal sealing lines is an exhaust chamber 28, and the sealing lines at both ends of the exhaust bag corresponding to the exhaust port 22 are treated with a clear varnish. One side of the outer main material 19 covers the overlapping part 29 of the main material and the other side of the outer main material, and the outer layer of the overlapping part of the outer main material forms an outer longitudinal sealing line 35 with the inner layer. That is to say, the inner main material is sealed with the inner main material, and the outer main material is sealed with the outer main material.

[0058] The sealing device preferably adopts an adhesive bonding method, which includes an adhesive bonding structure and a bonding structure; the additional bonding mechanism can apply adhesive to the main material or auxiliary material by spraying adhesive, and then bond the two together by guide rollers.

[0059] Appendix Figure 8 , 9The adhesive application structure includes an adhesive extrusion component, a first detector 44, and a drive component that drives the adhesive extrusion component to move laterally on the frame. The adhesive extrusion component includes an extrusion die 46, which is located above the forming template and between the outer layer 41 and the inner layer 42 of the roll overlap. If one longitudinal sealing line is required, the extrusion die extrudes one layer of adhesive; if three longitudinal sealing lines are required, the extrusion die extrudes three layers of adhesive. When processing the venting bag body of Embodiment 1, the extrusion die extrudes two layers of adhesive between the inner and outer layers of the main material overlap, forming two sealing lines 23. When processing the venting bag of Embodiment 6, the extrusion die forms three sealing lines between the inner and outer layers of the main material overlap and between the inner and outer layers of the outer main material overlap: two longitudinal sealing lines 23 for the inner main material and one longitudinal sealing line 35 for the outer layer. The first detector 44 moves laterally synchronously with the adhesive extrusion component. The first detector can be mounted on the adhesive extrusion component, and the first detector, adhesive extrusion component, and drive component are all connected to the controller. The first detector collects information about the outer edge of the roll overlap and sends it to the controller, such as the edge of the peelable outer film 18 in Embodiment 5 and the edge of the outer main material 19 in Embodiment 6. The controller sends instructions to the drive component based on the received information about the outer edge of the overlap, and the controller controls the operation of the adhesive extrusion component. Specifically, the first detector 44 collects the edge information of the outer layer of the roll overlap in real time to accurately determine the adhesive application position. The controller sends instructions to the drive component based on the information collected by the first detector. If the detected outer edge of the roll overlap shifts to the left, the drive component drives the adhesive extrusion component to move to the left; if the outer edge of the roll overlap shifts to the right, the drive component drives the adhesive extrusion component to move to the right, ensuring accurate adhesive application and preventing adhesive misalignment that could cause the two bags to stick together.

[0060] The adhesive extrusion component includes a barrel 47, an extrusion screw 48, an extrusion die 45, and a fourth motor that drives the extrusion screw 48 to rotate. The extrusion screw is located inside the barrel, and one end of the barrel has a feed inlet. For easy feeding, a hopper 49 is installed at the feed inlet to add plastic granules. The other end of the barrel 47 has a discharge outlet, which is connected to the extrusion die 45. The extrusion nozzle 46 is connected to the extrusion die. The fourth motor drives the extrusion screw 48 to rotate, and the rotation of the extrusion screw causes the material in the barrel to be extruded and conveyed towards the discharge outlet. During the extrusion and conveying process, the material is extruded and melted, and the barrel 47 can also be heated to accelerate the melting speed of the material. The melted material becomes an adhesive and is extruded from the extrusion die. The freshly extruded adhesive has good fluidity, requiring less adhesive for the same sealing area, resulting in lower costs, better adhesion, and faster and stronger bonding. Furthermore, no additional heating and shaping of the bag preform is required.

[0061] The extrusion nozzles 46 are provided in a plurality of longitudinally arranged portions, and the plurality of extrusion nozzles 46 are evenly arranged laterally. The extrusion head 45 is flat and extends longitudinally, so that the height of the extrusion head and the extrusion nozzles is low, which facilitates penetration into the space between the outer layer 41 and the inner layer 42 of the roll material overlap. After the overlap is coated with adhesive, it can quickly enter the sealing process, improving the sealing effect. The first detector 44 is a groove-shaped photoelectric eye, which has a groove 43 for the outer edge of the roll material overlap to enter. This facilitates the collection of information on the outer edge of the overlap, and the first detector collects information on the outer edge of the overlap more accurately.

[0062] See Figures 10-13. In the figures, the X-axis is horizontal (left-right direction); the Y-axis is vertical (front-back direction); and the Z-axis is vertical (up-down direction). The composite structure includes a composite pressure roller 61, which is connected to a fifth motor 86. The fifth motor drives the composite pressure roller to rotate. The composite pressure roller is rotatably mounted on a left side plate 62 and a right side plate 63. The left and right side plates are vertically slidably mounted on a mounting plate 71 via left and right guide rails 82, respectively. The left and right guide rails 82 are vertically arranged. In the figure, the left and right guide rails are respectively mounted on the left and right side plates. The mounting plate is provided with a left slide block and a right slide block, which are slidably mounted with the left and right guide rails, respectively. The mounting plate 71 is equipped with a first adjusting component for adjusting the height difference between the left and right side plates and a driving component 70 for driving the left and right side plates to rise and fall. In the non-working state, the driving component drives the left and right side plates to move upward along the left and right guide rails respectively, that is, drives the composite pressure roller 61 to move upward, moving it away from the lower roller. During operation, the driving component 70 drives the composite pressure roller to move downward. The composite pressure roller rotates and cooperates with the lower roller to pull and roll the roll material, so that the glued roll material is laminated together. The first adjusting component adjusts the height difference between the left and right side plates, 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 sealed part of the roll material is consistent, the composite pressure roller is parallel to the lower roller in the vertical direction. If the left side of the sealed part of the roll material 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 sealed part of the roll material is thinner than the left side, the right side of the composite pressure roller 61 is lower than the left side, so that the thickness of the glue on the left and right sides of the sealed part is consistent and moderate, and the roll material is subjected to the same pressure. The laminated roll material is flat and wrinkle-free.

[0063] The right side plate 63 is connected to a horizontal plate 67. The driving component is connected to the horizontal plate, and the fifth motor 86 is mounted on the right side plate 63. The left side plate 62 is connected to a mounting block 64, which is movably connected to the horizontal plate. The driving component drives the horizontal plate to rise and fall, which is equivalent to driving the left and right side plates to rise and fall. At the same time, the distance between the mounting block and the horizontal plate can be adjusted by the first adjusting component. The first adjusting component 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 against the horizontal plate 67 and controls the height distance between the horizontal plate and the mounting block 64. In the figure, the upper end of the first bolt passes through the first spring 65 and the horizontal plate 67 in sequence and is threadedly connected to the mounting block 64. The first bolt connects the mounting block to the horizontal plate. The elastic force of the first spring causes the mounting block and the horizontal plate to move closer to each other. The adjusting screw overcomes the elastic force of the first spring and presses against the horizontal plate. The adjusting screw moves down and presses against the horizontal 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, the distance between the mounting block and the horizontal plate becomes smaller under the action of the elastic force of the first spring. The left side plate moves down relative to the right side plate, and the left end of the composite pressure roller moves down. In this way, the angle between the composite pressure roller and the horizontal plane and the lower roller is adjusted. For ease of operation, the lower end of the adjusting screw passes through the mounting block and presses against the horizontal plate. A nut is threaded onto the upper end of the adjusting screw. The mounting plate has a limiting member 76 to restrict the vertical movement of the nut 77. The circumferential surface of the nut has transmission teeth that mesh with the worm gear 69. The adjusting screw 68 is vertically positioned; its upper end being too high would be inconvenient for operators. A horizontally positioned worm gear would facilitate operation. Rotation of the worm gear drives the nut to rotate, which in turn causes the adjusting screw to rise and fall, thus adjusting the relative height of the left and right side plates.

[0064] The mounting plate 71 is rotatably mounted on the movable plate 72 via a rotating shaft 73. The mounting plate is connected to a second adjusting component that adjusts its vertical angle. There is a tension difference between the upper and lower layers of the roll sealing section; typically, the lower layer has higher tension, while the upper layer has lower tension and is relatively loose. If the composite pressure roller 61 is parallel to the lower roller in the horizontal direction, the upper layer may deviate during composite traction, for example, shifting outwards. This invention allows the mounting plate to rotate vertically relative to the movable plate via the second adjusting component. This means the composite pressure roller swings forward or backward relative to the lower roller, causing the force exerted by the composite pressure roller on the upper layer to be biased inwards, offsetting the outward shift of the upper layer due to lower tension. This ensures that the upper and lower layers of the sealing section are aligned and properly positioned. The second adjusting component includes a second bolt 75 and a second spring 74. One end of the second bolt passes sequentially through the mounting plate 71 and the second spring, and is threadedly connected to the moving plate 72. When the second bolt 75 rotates clockwise, it reduces the distance between the right side of the mounting plate and the moving plate; that is, when the mounting plate rotates counterclockwise, the left end of the composite pressure roller swings backward and the right end forward. Conversely, when the second bolt 75 rotates counterclockwise, it reduces the distance between the right side of the mounting plate and the moving plate, causing the left end of the composite pressure roller to swing forward and the right end backward. Adjustment is convenient and quick. The mounting plate has a first connecting arm 79, which is connected to the rotating shaft 73. The moving plate 72 has a second connecting arm 80, which is rotatably connected to the rotating shaft 73. The first connecting arm 79 and the second connecting arm are vertically arranged and axially fixed relative to each other. There are two sets of each set of first connecting arms 79 and second connecting arms 80, with the first and second connecting arms in contact in each set, and the two first connecting arms positioned between the two second connecting arms. The structure is simple and easy to install and adjust.

[0065] The movable plate 72 is slidably mounted on the first crossbeam 83, and is connected to a third adjusting component that adjusts its lateral position on the frame. The third adjusting component includes a transverse screw 85, which is rotatably mounted on the frame. A third connecting arm 78 is provided on the back of the movable plate 72, and the transverse screw 85 is threadedly connected to the third connecting arm. A linear guide rail 84 is provided on the first crossbeam 83, and a slider is provided on the movable plate 72, which is slidably mounted on the linear guide rail 84. Rotating the transverse screw 85 causes the third connecting arm 78 to move laterally along the linear guide rail 84 on the first crossbeam. That is, according to the sealing position, the lateral position of the composite pressure roller on the frame is adjusted by the third adjusting component to meet the processing needs of different specifications of bag bodies or bag blanks.

[0066] Figure 14-16The main material venting hole processing device and the auxiliary material venting hole processing device have the same structure. The main material venting hole processing device includes a brush roller 94 and a venting hole processing group 92; a second crossbeam 98 is provided on the frame; the venting hole processing group is slidably disposed on the second crossbeam, and the venting hole processing group 92 includes a movable seat 100, a swing block 104 and a rotating shaft 102. The movable seat is slidably disposed on the second crossbeam, the swing block 104 is swayed on the movable seat 100 via a pivot 103, and the rotating shaft 102 is rotatably disposed on the swing block, and the rotating shaft is connected to a first driving member that drives its rotation. A needle roller 101 or a blade 113 is mounted on the rotating shaft 102, and the swing block is connected to a second driving member that drives its swing. When processing venting holes in the coiled material, the second driving member drives the swing block, causing the needle roller 101 or blade 113 on the rotating shaft to press against the brush roller 94. The brush roller can be either an active roller or a passive roller, passing between the two to form venting holes on the coiled material 106. In this invention, during the conveying process of the roll material, the roll material passes through the needle roller 101 and the brush roller 94 or the blade 113 and the brush roller, and the roll material is rolled by the needle roller to form a circular exhaust hole 21, and rolled by the blade 113 to form a linear exhaust hole.

[0067] The first driving component includes a first motor 93, a first transmission wheel 109, a second transmission wheel 107, and a transmission belt 108. The first and second transmission wheels are respectively mounted on the output shaft and rotating shaft 102 of the first motor. The transmission belt is mounted on the first and second transmission wheels. The output shaft of the first motor is coaxially mounted with the pivot 103. The first motor is mounted on the movable seat 100. When the swing block swings, it causes the needle roller or blade on the rotating shaft to press or separate from the brush roller, but the first motor does not swing with the swing block, thus making the first motor run more stably. At the same time, the rotation of the rotating shaft driven by the first motor is not affected by the swing block, making the processing of the exhaust hole more stable. The second driving component includes a second motor 96, an eccentric wheel 116, and a connecting rod 115. 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. The eccentric wheel pulls or pushes the swing block to swing around the pivot through the connecting rod. When the swing block swings toward the brush roller 94, the needle roller or blade on the rotating shaft presses 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 faster, making the processing of the exhaust hole more stable and precise.

[0068] The blades 113 are provided with several pieces and are evenly distributed on the outer circumference of the sheet-shaped turntable 112. There is a gap 117 between adjacent blades, and the blades form a circle. The turntable has a central hole that matches the rotating shaft 102. The first motor 93 drives the rotating shaft to rotate, and the turntable rotates in opposite directions with the brush roller. The blades on the turntable form longitudinal intermittent linear cutting edges on the coil. The turntable is provided with several sets, all of which are sleeved on the rotating shaft. There is a partition plate 111 between adjacent turntables, and the blades on adjacent turntables are staggered. That is, the adjacent turntables are the first turntable and the second turntable. The blades on the first turntable are axially opposite to the gaps on the second turntable. Similarly, the blades on the second turntable are axially opposite to the gaps 117 on the first turntable. The adjacent linear cutting edges formed on the coil are also staggered. The linear cutting edges are linear vent holes. The turntables are arranged laterally on the rotating shaft, which can form multiple transverse linear cutting edges on the coil. The staggered linear cutting edges improve the flow of the vent holes. A fixing plate 110 is mounted on the rotating shaft. The fixing plate has locking holes, and locking bolts are fitted into the locking holes. The turntable and the isolation plate are respectively provided with a first through hole 118 and a second through hole 114 that are axially connected to the mounting holes. The locking bolts pass through the first through holes and the second through holes and are threadedly connected to the locking holes. This installation method is convenient, and the isolation plates space the turntables apart, which in turn space the linear cutting edges on the roll material, thus avoiding damage to the strength and firmness of the roll bag.

[0069] The second crossbeam is equipped with a guide rail 95 and a first adjusting screw 97. A slide 99 is provided on the guide rail 95. The first adjusting screw is connected to a third motor and is threadedly connected to a first nut. The slide and the first nut are mounted on the movable seat 100. The third motor drives the first adjusting screw to rotate, which causes the movable seat to move laterally along the guide rail, adjusting the lateral machining position of the exhaust hole.

[0070] To precisely control the processing position of the vent hole, a color mark sensor 105 is installed on the roll material conveying path. The second drive and the color mark sensor are both connected to the controller. The controller sends a command to the second drive based on the color mark information collected by the color mark sensor on the roll material. The second drive drives the swing block 104 to swing around the pivot 103, so that the needle roller 101 or blade 113 on the rotating shaft 102 presses against the brush roller 94, or the needle roller or blade on the rotating shaft separates from the brush roller. This precisely controls the position of the vent hole and improves the quality of the vent bag.

[0071] Figure 17-18The anti-adhesion processing mechanism includes an anti-adhesion pressure roller 139, a pressure roller assembly, and a fourth crossbeam. The anti-adhesion pressure roller is rotatably mounted on the frame. The pressure roller assembly includes a bracket 146, an embossing wheel 138, and a third driving component 137 for driving the embossing wheel to rise and fall. The embossing wheel is rotatably mounted on the bracket, and the surface of the embossing wheel is evenly distributed with protrusions. The pressure roller assembly is laterally slidably mounted on the fourth crossbeam to adjust the lateral position of the embossing wheel on the frame. The fourth crossbeam is mounted on the frame and moves the pressure roller assembly laterally according to the width of the roll 106 and the position of the protrusions to make it correspond to the processing position on the roll, thus accurately processing the position. During the roll embossing process, the roll passes between the embossing wheel 138 and the anti-adhesion pressure roller 139. The third driving component 137 drives the embossing wheel to press against the anti-adhesion pressure roller, forming anti-adhesion protrusions on the roll. If the roll material does not require anti-adhesion protrusion processing, the third drive unit drives the embossing wheel to lift up, and the embossing wheel separates from the anti-adhesion pressure roller. When the roll material passes through the anti-adhesion station, it only goes around the anti-adhesion pressure roller and will not be rolled by the embossing wheel, so no protrusion will be formed.

[0072] The third driving component 137 provides a buffering force when the embossing wheel and the anti-adhesion roller are pressed together. For example, a spring can be installed between the embossing wheel and the anti-adhesion roller, and the spring force can provide a certain buffering effect. Alternatively, the third driving component can be a cylinder. When the cylinder drives the embossing wheel and the anti-adhesion roller to press together, the cylinder can retract, which also provides a certain buffering force. It is preferable to use a rubber roller for the anti-adhesion roller. This ensures that the embossing wheel and the anti-adhesion roller have appropriate pressing force, so that the surface of the rolled material is raised after rolling. At the same time, it avoids damage to the rolled material caused by excessive hard pressing force between the embossing wheel and the anti-adhesion roller, thus ensuring the rolling quality and rolling effect.

[0073] The fourth crossbeam is connected to a fourth driving component that drives it to move up and down on the frame. The fourth driving component is mounted on the frame. When threading the film or changing the embossing roller, the third driving component drives the embossing roller away from the anti-adhesion roller, and the fourth driving component drives the fourth crossbeam away from the anti-adhesion roller. This double increase in the distance between the embossing roller and the anti-adhesion roller facilitates film threading and embossing roller replacement, and prevents scratches or tears in the roll material due to insufficient distance between the embossing roller and the anti-adhesion roller. The fourth crossbeam includes an upper crossbeam 135 and a lower crossbeam 142. The pressure roller group includes an upper pressure roller group and a lower pressure roller group 140. The upper pressure roller group is slidably mounted on the upper crossbeam, and the lower pressure roller group is slidably mounted on the lower crossbeam. The roll material is wound around the anti-adhesion roller. The upper and lower pressure roller groups increase the number of pressure roller groups. Since each embossing roller is driven by an independent third driving component, the required pressure roller group can be selected for operation as needed, which is convenient for operation. The upper crossbeam is equipped with an upper slide rail 136, on which several upper sliding seats 147 are slidably mounted. The upper sliding seats are locked to the upper slide rail by locking bolts. The third drive component 137 of the upper pressure roller assembly is mounted on the upper sliding seats. The bracket 146 of the upper pressure roller assembly is connected to the third drive component. The position of the upper pressure roller assembly can be adjusted laterally as needed, and then locked by locking bolts after adjustment, making operation simple. Similarly, the lower crossbeam is equipped with a lower slide rail 141, on which several lower sliding seats are slidably mounted. The lower sliding seats are locked to the lower slide rail by locking bolts. The third drive component of the lower pressure roller assembly is mounted on the upper sliding seats, and the bracket of the lower pressure roller assembly is connected to the third drive component. In the attached diagram, the upper crossbeam is connected to the fourth drive component, and the lower crossbeam is fixed to the frame. The lower crossbeam can also have a lifting function to keep the embossing rollers away from the anti-adhesion rollers during die-cutting or roller pressing. The fourth driving component includes a sixth motor 143 and an eccentric wheel shaft 145. Both the output shaft of the sixth motor and the eccentric wheel shaft are equipped with transmission wheels, and the transmission wheels are fitted with a first transmission belt 144. First eccentric wheels 134 are mounted at both ends of the eccentric wheel shaft. A first connecting rod is rotatably connected to each of the first eccentric wheels. The other end of the first connecting rod is connected to an upper crossbeam 135. The upper crossbeam is slidably mounted on a third guide rail, which is vertically mounted on the frame. The sixth motor drives the eccentric wheel shaft to rotate via the transmission wheels and the first transmission belt. The eccentric wheel shaft drives the first eccentric wheels to rotate, and the first eccentric wheels, in turn, drive the upper crossbeam 135 to move up and down along the third guide rail via the first connecting rod, resulting in more stable mechanical transmission.

[0074] To precisely control the processing position of the protrusions on the roll material, a color mark sensor 132 is installed on the roll material conveying path. The third drive component 137 and the color mark sensor are both connected to the controller. The controller sends a command to the third drive component based on the color mark information collected by the color mark sensor on the roll material. The third drive component drives the embossing wheel to press against the anti-adhesion roller or drives the embossing wheel to lift up and separate from the anti-adhesion roller. This precisely controls the position of the embossing on the roll material and improves the quality of the air-release bag.

[0075] Figure 19-21 The winding mechanism includes a winding power roller 155, a moving component that causes the bag blank 151 to reciprocate laterally and achieves lateral misalignment of the wound bag blank, and a second detector 154 that collects edge information of the bag blank. The wound bag blank can also be referred to as a bag blank roll 157. The winding power roller is connected to a motor, and the bag blank is conveyed in the forward direction. The winding power roller 155 is in front of the moving component. The bag blank is wound around the winding power roller and onto the winding shaft 156. The winding shaft is close to the winding power roller, and its surface is always in contact with the winding power roller 155. When the winding power roller rotates, it drives the winding shaft to rotate through friction. The two rotate in opposite directions, and the bag blank is wound onto the winding shaft. The second detector 154 and the moving component are both connected to a controller. The second detector sends the collected edge information of the bag blank 151 to the controller, and the controller sends instructions to the moving component based on the received edge information of the bag blank. The second detector is a slotted photoelectric sensor and is located in front of the moving part. That is, the bag blank being pulled forward passes through the slotted photoelectric sensor, and the slotted photoelectric sensor continuously collects edge information of the bag blank.

[0076] The moving component causes the bag blank to move laterally back and forth. The range of this lateral movement is controlled by the controller. For example, if the bag blank moves 6 centimeters laterally, and the second detector detects that the edge of the bag blank has shifted 3 centimeters to the left, the controller sends a command to the moving component to shift the bag blank to the right. If the second detector detects that the edge of the bag blank has shifted 3 centimeters to the right, the controller sends a command to the moving component to shift the bag blank to the left. This process is repeated to precisely control the range of the bag blank's lateral movement. At the same time, the left and right shifts of the bag blank cause lateral misalignment of the bag blank on the take-up shaft. The adjacent inner and outer layers of the bag blank are staggered laterally, and the larger number of layers are evenly distributed laterally, so they are not concentrated in one place. For example, the middle longitudinal seal is thicker and 5 cm wide, while other parts are thinner. After the laterally staggered winding, assuming the offset range is 6 cm, the middle longitudinal seal of the wound bag blank roll 157 is laterally expanded to 11 cm. The lateral thickness distribution is even, so it is not easy to collapse and more can be wound at one time. Moreover, one side edge of the inner layer is covered by the outer layer. As the layers are wound one by one, the edge of the inner layer is compacted, the side crease is more stable, and the formed bag is straighter.

[0077] The moving component includes a first moving seat 158 ​​and a fifth driving member that drives the first moving seat to move left and right or swing back and forth. A first guide roller 152 and a second guide roller 153 are rotatably mounted on the first moving seat. The second guide roller is positioned in front of the first guide roller, and the bag blank passes over the first and second guide rollers in sequence. When the first moving seat moves to the right or swings clockwise, the bag blank shifts to the right; conversely, it shifts to the left. Swinging the first moving seat is preferred to reduce the impact on the bag blank in the input direction. The first moving seat is slidably mounted on a first guide rail 161 and a second guide rail 162. The first and second guide rails are inclined on the machine base and are longitudinally symmetrical. 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 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 laterally. The seventh motor drives the telescopic rod to extend and retract, which in turn causes the first movable seat to swing back and forth along the first and second guide rails, making the mechanical transmission more stable. When the telescopic rod retracts, 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. The first guide roller 152 and the second guide roller 153 swing clockwise, and the bag blank being pulled forward shifts to the right accordingly. When the telescopic rod extends, the first movable seat swings in opposite directions along the first and second guide rails, 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. The first guide roller and the second guide roller tilt in opposite directions, and the bag blank being pulled forward shifts to the left accordingly, thus causing the wound bag blank roll to be laterally misaligned.
