Description

Technical Field

[0001] This application relates to the technical field of bag making machines, and in particular to a variable fork bottom bag making machine for one-outlet-two-pearl cotton thermal insulation bags. Background Technology

[0002] A bag-making machine is a machine used to produce bags. Bag-making machines typically fold pearl cotton and then feed the pearl cotton into the bag-making machine.

[0003] During the conveying process of folded pearl cotton, the opening of the pearl cotton faces the side of the bag making machine. The bag making machine uses triangular cross heating plates to heat the pearl cotton to seal the edges. An insulated bag is formed between two adjacent heat-sealed edges, thus forming insulated bags arranged along the conveying direction.

[0004] After the pearl cotton is sealed, as shown Figure 1 As shown, the bag includes a pearl cotton body 36, with straight edges 37 for sealing arranged along the length of the pearl cotton body 36. Opposite to each straight edge 37 are inclined edges 38 for sealing. An insulated bag body is formed between two adjacent straight edges 37, with the opening of the insulated bag body located at the end furthest from the inclined edges 38. After the pearl cotton is sealed, the insulated bag body is separated piece by piece by cutting the sealed edges, and the triangular sections are removed. However, most existing bag-making machines can only seal one row of pearl cotton, resulting in low production efficiency. Summary of the Invention

[0005] To improve the production efficiency of thermal insulation bags, this application provides a variable fork bottom bag making machine for producing two pearl cotton thermal insulation bags in one output.

[0006] This application provides a variable fork bottom bag making machine for one-outlet-two-outlet pearl cotton thermal insulation bags, which adopts the following technical solution:

[0007] A variable-fork bottom bag making machine for producing two-outlet pearl cotton thermal bags includes: a machine body, a conveying mechanism, a pressing mechanism, and a heating element. The conveying mechanism is disposed on the machine body and is used to drive the pearl cotton to move stepwise on the machine body. The pressing mechanisms are evenly spaced on the machine body, and each pressing mechanism includes:

[0008] The first mounting beam is mounted on the machine body;

[0009] The second mounting beam is located above the first mounting beam and can move up and down on the first mounting beam;

[0010] A connecting component is disposed between the first mounting beam and the second mounting beam to support the second mounting beam;

[0011] Two straight-edge blades are respectively mounted on opposite sides of the first and second mounting beams, and the length of each straight-edge blade extends perpendicular to the feeding direction. A space is provided between the two straight-edge blades for the pearl cotton to pass through.

[0012] The oblique blade group corresponds to the straight edge blade. Each straight edge blade has two oblique blade groups. The two oblique blade groups are respectively arranged at the two ends of the straight edge blade that are far apart from each other, so as to press the sides of the two rows of pearl cotton in parallel. Each oblique blade group includes two oblique blades. The two oblique blades are respectively arranged on opposite sides of the straight edge blade, and the distance between the two oblique blades in the same group gradually increases away from the middle of the straight edge blade.

[0013] The connecting component is provided with a push-pull member between itself and the machine body to move the connecting component, thereby moving the second mounting beam toward or away from the first mounting beam. The heating element is provided on the pressing mechanism near the feeding end of the machine body. The heating element is electrically connected to the beveled blade and the straight blade in the corresponding pressing mechanism to heat the beveled blade and the straight blade, so that the beveled blade and the straight blade can perform heat-melt bonding of the pearl cotton.

[0014] By adopting the above technical solution, the conveying mechanism feeds the pearl cotton, so that the pearl cotton is pressed by the straight edge knife and the inclined plate knife when it passes through the pressing mechanism, so as to heat and seal the edge. Since the inclined edge knife is set on both sides of the straight edge knife, it can convey two rows of pearl cotton side by side and seal the edge of the two rows of pearl cotton at the same time, thereby improving the production efficiency of the thermal insulation bag.

[0015] Optionally, the connection component includes

[0016] The first guide rod slides vertically through the first mounting beam and the second mounting beam, and its bottom engages with the push-pull member so that the push-pull member drives the first guide rod to move up and down.

[0017] A locking head is located at the top of the first guide rod;

[0018] A first elastic element is disposed between the locking head and the second mounting beam;

[0019] A second guide rod is disposed on the first mounting beam and slides vertically through the second mounting beam; and

[0020] The second elastic element is disposed between the first mounting beam and the second mounting beam;

[0021] When the push-pull member moves the first guide rod downward, the second mounting beam presses down on the pearl cotton under the push of the first elastic member. When the push-pull member moves the first guide rod upward, the second mounting beam moves upward away from the pearl cotton under the drive of the first elastic member and the second elastic member.

[0022] By adopting the above technical solution, the movement of the second mounting beam is guided by the first guide rod and the second guide rod, thereby improving the stability of the second mounting beam during movement.

[0023] Optionally, the locking head is threadedly movable on the first guide rod.

[0024] By adopting the above technical solution, the locking head thread can be moved to adjust the downward pressure on the second mounting beam.

[0025] Optionally, the beveled blade slides along the length of the straight blade on the straight blade, and the pressing mechanism is provided with an adjusting member for moving the beveled blade.

[0026] By adopting the above technical solution, the beveled blade is moved by the adjusting component to adjust the size of the resulting cross bottom.

[0027] Optionally, the first mounting beam moves along the feeding direction on the machine body, and the machine body and the first mounting beam are provided with a limiting member for limiting the first mounting beam.

[0028] By adopting the above technical solution, the length of the insulation bag can be adjusted by adjusting the position of the first mounting beam.

[0029] Optionally, the bag making machine also includes a cutting mechanism, which includes a base, a cutting blade, and a power source. The base is located at the discharge end of the machine body. The length direction of the cutting blade is parallel to the length direction of the straight edge blade. The base has a support frame for mounting the power source. The power source works in conjunction with the cutting blade to drive the cutting blade to move up and down to cut the pearl cotton into thermal insulation bags.

[0030] By adopting the above technical solution, the straight edges of the sealing edge are cut with a cutting blade to form an insulated bag, thereby improving the production efficiency of insulated bags.

[0031] Optionally, the bag making machine also includes a material conveying mechanism and a material collecting mechanism. The material conveying mechanism is close to the cutting mechanism, and the material collecting mechanism is located on the side of the material conveying mechanism away from the cutting mechanism. The material conveying mechanism is used to receive the insulated bag and transport the insulated bag to the material collecting mechanism for collection.

[0032] Optionally, the material conveying mechanism includes a base and a conveyor belt, with the conveyor belt conveying material onto the base; the material collecting mechanism includes a platform and a collecting bin, with the collecting bin opening upwards, and the collecting bin being movable onto the platform opposite the conveyor belt, so that the insulation bag on the conveyor belt falls into the collecting bin;

[0033] The material collection box has a receiving component that moves up and down. The receiving component includes a partition and a receiving plate. The surface of the receiving plate extends along the horizontal plane. The partition is vertically connected to the top surface of the receiving plate so as to form two symmetrically distributed storage cavities for storing the heat preservation bags. When the material collection box is opposite to the conveyor belt, the two storage cavities are respectively opposite to two rows of heat preservation bags.

[0034] A locking device is provided between the partition and the collection box to limit the movement of the partition, and a linkage component is provided between the partition and the conveyor belt. Before the conveyor belt delivers a row of insulation bags to the collection box, the partition is driven to resist the limiting effect of the locking device, causing the partition to move downward a certain distance each time. The downward distance of the partition each time is similar to the thickness of the insulation bag.

[0035] By adopting the above technical solution, through the cooperation of the linkage component and the partition, the receiving plate gradually moves down with the conveying of the insulation bag, so that the displacement height of the insulation bag falling into the collection box each time is relatively low, thereby improving the stacking stability of the insulation bag and making it less likely for the insulation bag to tilt in the collection box.

[0036] Optionally, the linkage component includes a first tooth and a second tooth, and the collection box has clearance holes on opposite sides near or away from the base to make way for the partition. The first tooth is evenly distributed vertically on the side wall of the partition and extends out of the side wall of the partition from the clearance holes.

[0037] The second teeth are evenly spaced along the conveyor belt. When the conveyor belt moves the second teeth close to the collection box, the second teeth enter between two adjacent first teeth and abut against the first teeth below them, so as to drive the first teeth to move downward against the limiting action of the snap-fit ​​member. After the first teeth drive the partition and the receiving plate to move downward a certain distance, the second teeth separate from the first teeth, and the snap-fit ​​member limits the partition again.

[0038] By adopting the above technical solution, the first tooth and the second tooth cooperate to make the partition move automatically downward as it is conveyed by the conveyor belt, thereby improving the convenience of moving the partition.

[0039] By adopting the above technical solution, the bottom of the collection box has a clearance cavity to allow the collection box to slide on the platform. Two collection boxes can be distributed on the platform along the conveying direction perpendicular to the conveyor belt. The platform has a positioning member for positioning one of the collection boxes. The collection box that cooperates with the positioning member is opposite to the conveyor belt. The platform is linked to a shifting member so that when the positioning member releases the restriction on one of the collection boxes, it pushes the other collection box to move so that the other collection box is opposite to the positioning member.

[0040] Optionally, the material collection bin can be replaced using a switching device to allow for quick replacement once the bin is full, ensuring continuous material receiving from the insulation bags.

[0041] In summary, this application has the following beneficial effects:

[0042] By setting beveled blades on both sides of the straight blade, two rows of pearl cotton can be sealed at the same time, thereby improving the production efficiency of the thermal insulation bag. Attached Figure Description

[0053] The following is in conjunction with the appendix Figure 2-9 This application will be described in further detail.

[0054] This application discloses a variable-fork bottom bag making machine for producing two pearl cotton thermal bags in one output. (See also...) Figure 2 The one-outlet-two-output pearl cotton insulation bag variable fork bottom bag making machine includes a machine body 1, a conveying mechanism, a pressing mechanism, a cutting mechanism, a material conveying mechanism, a material collecting mechanism, and a heating element 2. The conveying mechanism is set on the feeding end of the machine body 1 to convey pearl cotton. Multiple pressing mechanisms are evenly distributed on the machine body 1 along the feeding direction to heat melt and cool the pearl cotton. The heating element 2 is set on the pressing mechanism near the feeding end of the machine body 1. The cutting mechanism is set on the output end of the machine body 1 to cut the pearl cotton to form individual insulation bags. The material conveying mechanism is used to receive the insulation bags and convey them to the material collecting mechanism for collection.

[0055] Reference Figure 3The conveying mechanism includes mounting bases 26, conveying rollers 27, and conveying motors 28. Two mounting bases 26 are bolted to opposite sides of the feed end of the machine body 1. Two conveying rollers 27 are provided, with their ends rotatably connected to the two mounting bases 26, and the two conveying rollers 27 are parallel and vertically distributed. Each conveying motor 28 corresponds to one conveying roller 27, and the output end of each conveying motor 28 is coaxially connected to the corresponding conveying roller 27. The two conveying motors 28 drive the two conveying rollers 27 to rotate synchronously in opposite directions.

[0056] There is a space between the two conveyor rollers 27 for the folded pearl cotton to pass through. When the pearl cotton passes between the two conveyor rollers 27, it is squeezed, which causes the rotation of the conveyor rollers 27 to move the pearl cotton towards the discharge end of the machine body 1. The conveyor motor 28 will stop for a certain period of time after driving the conveyor rollers 27 to rotate a certain number of times, so that the pearl cotton can move in steps. This allows the pressing mechanism and the cutting mechanism to operate the pearl cotton when it stops rotating. The number of rotations of the conveyor motor 28 each time can be adjusted as needed.

[0057] Reference Figure 2 and Figure 4 Four sets of pressing and holding mechanisms are arranged along the feeding direction of the machine body 1. Combined with... Figure 5 Each pressing mechanism includes a first mounting beam 3, a second mounting beam 4, a connecting assembly 5, a straight-edged blade 6, and a set of oblique blades 7. The first mounting beam 3 and the second mounting beam 4 are both elongated strips extending horizontally and are parallel to each other, with the first mounting beam 3 located directly below the second mounting beam 4. The connecting assembly 5 cooperates with the first mounting beam 3 and the second mounting beam 4 to support the second mounting beam 4. Each pressing mechanism has two straight-edged blades 6, each elongated strip, fixedly connected to opposite sides of the first mounting beam 3 and the second mounting beam 4, with the length of the straight-edged blades parallel to both beams. Each straight-edged blade 6 corresponds to two sets of oblique blades 7, which are installed at opposite ends of the straight-edged blade 6.

[0058] Each beveled blade group 7 includes two beveled blades 71, which are respectively placed on opposite sides of the straight blade 6. Both beveled blades 71 are inclined relative to the straight blade 6, specifically, the distance between the two beveled blades 71 in the same group gradually increases away from the midpoint of the straight blade 6.

[0059] When the pressing mechanism cooperates with the machine body 1, the first mounting beam 3 is mounted on the machine body 1. The length direction of the first mounting beam 3 is perpendicular to the pearl cotton feeding direction. The pearl cotton passes between the two straight-edged blades 6, and the first mounting beam 3 can move on the machine body 1 along the pearl cotton feeding direction. There is a limiting member 9 between the machine body 1 and the first mounting beam 3 to prevent the first mounting beam 3 from moving arbitrarily. There is a push-pull member 8 between the connecting assembly 5 and the machine body 1. The push-pull member 8 drives the connecting assembly 5 to move up and down, thereby driving the second mounting beam 4 to move up and down, so that the straight-edged blades 6 and the beveled blades 71 on the second mounting beam 4 press the pearl cotton down, so that the pearl cotton is clamped between the upper and lower opposite straight-edged blades 6 and beveled blades 71.

[0060] Reference Figure 3 and Figure 4 Heating elements 2 are installed on all three sets of pressing components near the feed end of the machine body 1. Heating elements 2 are existing electric heating boxes. The straight edge knife 6 and the beveled edge knife 71 contain electric heating wires. The electric heating box is connected to the straight edge knife 6 and the beveled edge knife 71 located at the same end by wires to heat the electric heating wires between the straight edge knife 6 and the beveled edge knife 71. The electric heating wires transfer heat to the straight edge knife 6 and the beveled edge knife 71, so that the straight edge knife 6 and the beveled edge knife 71 clamp the pearl cotton and heat the pearl cotton at the same time, so as to melt the corresponding part of the pearl cotton, thereby bonding the folded pearl cotton together, and then sealing the edge of the pearl cotton. The pressing mechanism closest to the discharge end of the machine body 1 does not cooperate with the heating element 2. When the edge-sealing part of the pearl cotton reaches this pressing mechanism, the straight edge knife 6 and the beveled edge knife 71 clamp the edge to further fix and cool the edge.

[0061] In use, two rows of folded pearl cotton are simultaneously fed into the conveyor roller 27. The distribution direction of the two rows of pearl cotton is perpendicular to the feeding direction of the pearl cotton, and the openings of the two rows of pearl cotton are opposite each other. When the two rows of pearl cotton reach the pressing mechanism, the beveled blades 71 at the far ends of the first mounting beam 3 correspond to the far sides of the two rows of pearl cotton, so that the beveled blades 71 at the far ends of the first mounting beam 3 seal the edges of the two rows of pearl cotton respectively.

[0062] Reference Figure 2 and Figure 4Specifically, each pressing assembly has two sets of connecting components 5, which are symmetrically arranged at the two far apart ends of the first mounting beam 3. Each set of connecting components 5 includes a first guide rod 51, a locking head 52, a first elastic element 53, a second guide rod 54, and a second elastic element 55. Both the first elastic element 53 and the second elastic element 55 are springs, and the elastic force of the first elastic element 53 is greater than that of the second elastic element 55. The first guide rod 51 slides vertically through the corresponding first mounting beam 3 and second mounting beam 4. The first guide rod 51 is in the shape of a round rod. The locking head 52 is coaxially threaded onto the top outer wall of the first guide rod 51. The first elastic element 53 is coaxially threaded onto the outer wall of the first guide rod 51, and the far apart ends of the first elastic element 53 abut against the lower surface of the locking head 52 and the upper surface of the second mounting beam 4, respectively.

[0063] The second guide rod 54 is round. There are two second guide rods 54 in each set of connecting components 5. The two second guide rods 54 are fixed to opposite sides of the first mounting beam 3, and the axis of the second guide rod 54 extends vertically to pass through the second mounting beam 4. The second elastic element 55 corresponds to the second guide rod 54 and is coaxially sleeved on the corresponding second guide rod 54. The two ends of the second elastic element 55 that are far apart from each other abut against the opposite surfaces of the first mounting beam 3 and the second mounting beam 4.

[0064] Reference Figure 3 and Figure 4 The push-pull component 8 has two sets, respectively arranged on opposite sides of the machine body 1. Each set of push-pull components 8 includes a push-pull cylinder 81 and a synchronizing rod 82. The synchronizing rod 82 is elongated and extends along the pearl cotton feeding direction, and is opposite to the side of the machine body 1. The push-pull cylinder 81 is installed on the side of the machine body 1, and the piston rod of the push-pull cylinder 81 is connected to the bottom of the synchronizing rod 82 to drive the synchronizing rod 82 to move up and down. A connecting block 29 is fixed to the bottom of the first guide rod 51, and a dovetail-shaped stroke block 30 is fixed to the bottom of the connecting block 29. A stroke groove 31 is opened on the top of the synchronizing rod 82 for the stroke block 30 to slide. All stroke blocks 30 located on the same side of the machine body 1 slide simultaneously in the same stroke groove 31 along the pearl cotton feeding direction, and the dovetail shape of the stroke block 30 restricts the stroke block 30 from disengaging upward from the stroke groove 31.

[0065] When the push-pull cylinder 81 moves the synchronizing rod 82 downward, the connecting block 29 moves the first guide rod 51 downward, locking and pressing the first elastic element 53. The first elastic element 53 causes the second mounting beam 4 to move downward against the supporting force of the second elastic element 55. As a result, the straight edge blade 6 and the beveled edge blade 71 on the second mounting beam 4 press the pearl cotton downward onto the straight edge blade 6 and the beveled edge blade 71 on the first mounting beam 3. When the push-pull cylinder 81 moves the synchronizing rod 82 upward, the connecting block 29 moves the first guide rod 51 upward to release the first elastic element 53. Under the reset action of the first elastic element 53 and the supporting action of the second elastic element 55, the second mounting beam 4 resets, causing the pearl cotton to detach from the straight edge blade 6 and the beveled edge blade 71.

[0066] The limiting component 9 includes a rack 91, a rotating shaft 92, and a gear 93. Two racks 91 are fixed to opposite sides of the machine body 1 and extend along the feeding direction of the pearl cotton. The ends of the second mounting beam 4 have extension seats opposite to the racks 91. Each first mounting beam 3 has two rotating shafts 92, which are rotatably connected to extension seats at opposite ends of the first mounting beam 3. The axis of the rotating shafts 92 is perpendicular to the length direction of the rack 91. The gears 93 correspond one-to-one with the rotating shafts 92, coaxially fixedly sleeved on the corresponding rotating shafts 92 and meshing with the rack 91 on the same side. When the pressing mechanism needs to be moved, the rotating shafts 92 at both ends of the second mounting beam 4 are rotated simultaneously, causing the gears 93 to move on the racks 91 as they rotate. When the pressing mechanism needs to be limited, the pressing mechanism is limited by the meshing action of the gears 93 and racks 91.

[0067] In addition, in order to improve the stability of the pressing mechanism when it moves, the part of the first mounting beam 3 that extends beyond the side wall of the body 1 is fixed with a guide seat 32. A guide groove 33 is provided on the outer side wall of the rack 91 along its own length direction. The guide seat 32 has a part that extends into the guide groove 33 to slide in the guide groove 33, so as to prevent the first mounting beam 3 from moving up or down when the first mounting beam 3 moves along the length direction of the rack 91, thereby making it difficult for the gear 93 to disengage from the rack 91.

[0068] Reference Figure 4Furthermore, the beveled blade 71 slides along the length of the straight blade 6 on the straight blade 6 to adjust the sealing edge size of the triangular fork bottom formed by the beveled blade 71, and both the first and second crossbeams have adjusting members 34 for moving the corresponding beveled blade 71. Specifically, taking the second crossbeam and the beveled blade 71 as an example, the end of the second crossbeam also has an extension seat. The adjusting component 34 includes a slider 341, a connecting frame 342, and a rotating screw 343. The slider 341 corresponds one-to-one with the beveled blade 71 and is fixed on the corresponding beveled blade 71. The two sides of the beveled blade 71 facing away from the second crossbeam are fixed with guide strips 344 along their own length direction for sliding connection of the sliders 341 on both sides of the second crossbeam. The connecting frame 342 connects the sliders 341 of the two beveled blades 71 in the same beveled blade group 7. The rotating screw 343 corresponds one-to-one with the beveled blade group 7 and is rotatably connected to the extension seat. One of the sliders 341 is threaded onto the outer wall of the rotating screw 343 so that rotating the rotating screw 343 can drive the beveled blades 71 in the same group to move along the length direction of the straight blade 6. The way the first crossbeam and the beveled blade 71 cooperate is the same as that of the first crossbeam.

[0069] Reference Figure 3 The cutting mechanism includes a base 10, a cutting blade 11, and a power source 12. The base 10 is fixed to the discharge end of the machine body 1. The length direction of the base 10 is horizontal and perpendicular to the feeding direction of the pearl cotton. A strip-shaped clearance groove is provided on the base 10. Vertically upward support frames 13 are fixed at both ends of the base 10. The power source 12 is mounted on the support frame 13. The power source 12 is a cylinder, and the output end of the power source 12 is connected to the cutting blade 11. The length direction of the cutting blade 11 is parallel to the length direction of the base 10. The cutting blade 11 is opposite to the clearance groove. After the pearl cotton is sealed, it is fed out from between the cutting blade 11 and the base 10.

[0070] When the pressing mechanism presses down on the pearl cotton, the power source 12 drives the cutting blade 11 downward to cut the straight edge of the sealed pearl cotton. After cutting, it moves upward away from the pearl cotton to cut the pearl cotton into insulation bags. Since two rows of pearl cotton are conveyed together, each cutting blade 11 cuts two pearl cotton pieces, and the two rows of pearl cotton after pressing the edges are as follows: Figure 6 As shown.

[0071] Reference Figure 2 and Figure 7 Regarding the material conveying mechanism, the material conveying mechanism includes a base 14 and a conveyor belt 15. The conveyor belt 15 is an existing plate chain conveyor belt 15. The conveyor belt 15 is conveyed on the base 14 through the cooperation of a chain, sprocket and motor. The conveying direction of the conveyor belt 15 is consistent with the feeding direction of the pearl cotton. The conveyor belt 15 is close to the discharge end of the machine body 1. Each two cut insulation bags can fall onto the conveyor belt 15 for conveying, so as to convey the insulation bags to the collection mechanism for collection.

[0072] Reference Figure 7 and Figure 8 The material collection mechanism includes a platform 16 and a material collection box 17. The platform 16 is shaped like a directional plate and is fixed to the ground. The platform 16 is located at the end of the base 14 away from the machine body 1. The length direction of the platform 16 is perpendicular to the feeding direction of the conveyor belt 15. The collection box 17 is a square box with an upward opening. The bottom of the collection box 17 forms a relief cavity 23 that cooperates with the platform 16. The width of the relief cavity 23 is the same as the width of the platform 16, so that the collection box 17 can be slidably fitted onto the platform 16. Two collection boxes 17 can be placed on the platform 16. The platform 16 has a positioning component 24 for positioning one of the collection boxes 17. The positioning component 24 is an electric telescopic rod installed in the platform 16. The collection box 17 has a slot in the inner wall of the relief cavity 23 for inserting the telescopic end of the electric telescopic rod. When the collection box 17 moves on the platform 16 to be directly in front of the conveyor belt 15, the electric telescopic rod is aligned with the slot on the collection box 17, and the telescopic end of the electric telescopic rod can be moved out of the platform 16 and inserted into the slot.

[0073] Reference Figure 5 The platform 16 is linked to a shifting component 25, which includes a shifting cylinder 251, a shifting motor 252, and a shifting plate 253. The shifting cylinder 251 is installed on the frame located between the platform 16 and the base 14. The axis of the piston rod of the shifting cylinder 251 is parallel to the length direction of the platform 16. The piston end of the shifting cylinder 251 is connected to the shifting motor 252. The output end of the shifting motor 252 is connected to the shifting plate 253. The shifting plate 253 is elongated, and the shifting motor 252 can drive the shifting plate 253 to rotate relative to or offset from the collection box 17.

[0074] During the material receiving process of the positioned collection box 17, the piston rod of the shifting cylinder 251 extends and the shifting motor 252 drives the shifting plate 253 to rotate so that it is opposite to the other collection box 17. When the positioned collection box 17 is full of material, the positioning of the collection box 17 is released, and then the piston rod of the shifting cylinder 251 retracts to push the other collection box 17 to slide towards the base 14 so that it is opposite to the positioning part 24. The other collection box 17 also moves the full collection box 17 off the platform 16 so that the collection box 17 can be quickly replaced. When it is necessary to move the collection box 17 onto the platform 16, the shifting motor 252 drives the shifting plate 253 to rotate to a position opposite to the collection box 17 so that the collection box 17 can be moved onto the platform 16.

[0075] Reference Figure 7 and Figure 8In addition, each collection box 17 is equipped with a vertically movable receiving component 18. The receiving component 18 includes a partition 181 and a receiving plate 182. Both the partition 181 and the receiving plate 182 are square plates, with the receiving plate 182 extending horizontally and the partition 181 extending vertically. The receiving plate 182 slides up and down within the collection box 17. The lower end of the partition 181 is fixed to the upper surface of the receiving plate 182, and the height of the partition 181 is similar to the depth of the collection box 17. The partition 181 and the receiving plate 182 are... The inner wall of the collection box 17 together forms two storage cavities 19 for storing insulated bags, and the partition 181 extends beyond the side wall of the receiving plate 182 on opposite sides. The collection box 17 has clearance holes 22 on opposite sides to allow the partition 181 to slide. When the collection box 17 is opposite to the conveyor belt 15, the partition 181 is opposite to the middle of the conveyor belt 15, and the two storage cavities 19 are opposite to the two rows of insulated bags respectively.

[0076] There is a locking member 20 between the partition 181 and the collection box 17 to limit the partition 181. A linkage component 21 is provided between the partition 181 and the conveyor belt 15. Before the conveyor belt 15 sends a row of insulation bags into the collection box 17, the conveyor belt 15 and the partition 181 are linked by the linkage component 21, so that the partition 181 resists the limiting effect of the locking member 20 and moves downward a certain distance. Specifically, the distance that the partition 181 moves downward each time is equivalent to the thickness of the insulation bag.

[0077] Reference Figure 7 and Figure 8 The snap-fit ​​component 20 is a ball-head plunger, which is installed on the inner wall of the relief hole 22 in the collection box 17. The ball head of the ball-head plunger extends out of the inner wall of the relief hole 22. Multiple arc-shaped snap-fit ​​grooves 35 are evenly spaced along the height direction on the side wall of the partition 181 for the ball head of the ball-head plunger to abut. The distance between two adjacent snap-fit ​​grooves 35 is related to the thickness of the insulation bag. The ball head of the ball-head plunger abuts into the snap-fit ​​groove 35 to limit the partition 181.

[0078] Reference Figure 7 and Figure 9 The linkage component 21 includes a first tooth 211 and a second tooth 212. The first tooth 211 is evenly spaced vertically on the outer side wall of the partition 181 facing the base 14, and each first tooth 211 corresponds to a snap-fit ​​groove 35. The end of the first tooth 211 away from the partition 181 extends out of the outer side of the collection box 17 from the clearance opening. The second tooth 212 is evenly spaced along the conveying direction of the conveyor belt 15 at the middle position of the conveyor belt 15. The distance between two adjacent second teeth 212 is greater than the length of the insulation belt, and the conveying speed of the conveyor belt 15 is matched with the conveying speed of the pearl cotton so that each time the insulation bag falls onto the conveyor belt 15, the distance between two adjacent second teeth 212 is increased, and the insulation bag falls between two adjacent second teeth 212.

[0079] When the conveyor belt 15 moves the second tooth 212 to a position close to the collection box 17, the second tooth 212 will enter between two adjacent first teeth 211 and interfere with the first tooth 211 below. As the second tooth 212 continues to move downward, it will also move the first tooth 211 downward, giving the partition 181 a downward force. This causes the partition 181 to push the ball head of the ball head bolt into the inner wall of the relief hole 22 through the snap-fit ​​groove 35 of the ball head bolt. This causes the partition 181 to move the receiving plate 182 downward. After the partition 181 moves downward by the distance of one insulation bag, the conveyor belt will rotate the second tooth 212 to the lower side of the conveyor belt 15 and separate it from the first tooth 211. The ball head of the ball head bolt will then be opposite to and abut against the adjacent snap-fit ​​groove 35, thereby limiting the partition 181 again. Then the conveyor belt 15 will send the insulation bag into the collection box 17.

[0080] In use, first engage the snap-fit ​​groove 35 at the bottom of the partition 181 with the ball head bolt. At this time, the receiving plate 182 is close to the top of the collection box 17 and the lower side of the conveyor belt 15, so that the insulation bag falls into the collection box 17 with a lower downward height, thereby improving the stability of the insulation bag discharge and preventing the insulation bag from tilting in the collection box 17 and causing uneven stacking. As the insulation bag is discharged, the receiving plate 182 gradually moves down with the cooperation of the first tooth 211 and the second tooth 212, and the insulation bags are stacked in sequence. After the snap-fit ​​groove 35 at the top of the partition 181 engages with the ball head plunger and the insulation bag falls into the collection box 17, the collection box 17 is full of insulation bags. At this time, the positioning of the collection box 17 is released, and the next collection box 17 is pushed to the position opposite to the base 14 by the shift cylinder 251 to quickly replace the collection box 17 and ensure continuous discharge of insulation bags.

[0081] In addition, the first tooth 211 is pointed at one end near the base 14 to facilitate guiding the two insulated bags into the two storage cavities 19.

[0082] The implementation principle of the one-outlet-two-output pearl cotton thermal bag variable fork bottom bag making machine of this application embodiment is as follows: pearl cotton is fed from the feeding end of the machine body 1 and moves step by step, so that the straight edge knife 6 and the oblique edge knife 71 heat, seal and cool the pearl cotton. The pearl cotton is moved out from the discharge end of the machine body 1 and cut by the cutting knife 11 to form thermal bags. The thermal bags fall onto the conveyor belt 15 and are collected in the collection box 17 driven by the conveyor belt 15.

[0083] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
