Description

Technical Field

[0001] This application relates to the field of roll film packaging machine technology, and more particularly to a roll film packaging machine that can collect waste materials. Background Technology

[0002] Roll wrapping machines are automated packaging equipment used to package products. They are widely used in food, pharmaceuticals, daily necessities, and industrial products, and are one of the core pieces of equipment in modern packaging production lines.

[0003] When the roll film packaging machine is working, it uses roll film as the packaging material. First, the roll film is pressed together by hot melt welding to form a bag with a bag opening. Then, liquid is filled into the bag through the bag opening and the bag opening is sealed again by hot melt welding. Finally, each bag filled with liquid is cut around its perimeter and removed by suction cups.

[0004] The process involves cutting around the circumference of each liquid-filled bag and removing it. Each liquid-filled bag then separates from the remaining packaging material. Therefore, removing each liquid-filled bag continuously generates residual packaging material.

[0005] However, in existing roll wrapping machines, the continuously generated leftover packaging materials are first directly conveyed to the vicinity of the roll wrapping machine, and then manually collected and moved to the waste bin. As a result, the continuously generated leftover packaging materials are collected manually in a scattered state. Because the scattered leftover packaging materials occupy a lot of space, it is time-consuming, laborious and difficult to move them manually. Utility Model Content

[0038] refer to Figures 1 to 10 A preferred embodiment of the waste-collecting roll film packaging machine according to this application will be described in detail below, wherein the waste-collecting roll film packaging machine includes a device body 10, a film feeding assembly 20, a liquid filling assembly 30, a bag sealing and cutting assembly 40, a bag picking assembly 50 and a material receiving assembly 60.

[0039] Specifically, the device body 10 includes a mounting frame 11 and a film feeding unit 12. The film feeding unit 12 includes a film feeding roller 121. A first bag film 100 and a second bag film 200 with matching widths are fitted onto the film feeding roller 121 along the axial direction. The film feeding roller 121 is rotatably mounted on the mounting frame 11 so that the first bag film 100 and the second bag film 200 are fed out together by the rotation of the film feeding roller 121. That is, the first bag film 100 and the second bag film 200 fed out together from the film feeding roller 121 are conveyed in the same direction.

[0040] The film guiding assembly 20 is disposed on the mounting frame 11 in such a way that it can guide the first bag film 100 and the second bag film 200, which are being released together from the film dispensing roller 121 in a co-directional conveying state, to a relative conveying state.

[0041] The infusion assembly 30 is disposed near the mounting frame 11 and has at least one infusion end to inject a predetermined dose of liquid through at least one of the infusion ends.

[0042] The bag sealing and cutting assembly 40 includes a bag mounting frame 41, a pair of bag sealing units 42, and a pair of bag cutting units 43.

[0043] The sealing mounting bracket 41 is mounted on the mounting frame 11. The sealing mounting bracket 41 has a sealing channel 4101. The sealing channel 4101 extends along a direction perpendicular to the relative conveying direction of the first bag film 100 and the second bag film 200, and the width of the sealing channel 4101 is adapted to the width of the first bag film 100. The extension direction of one end of the sealing channel 4101 is located between the relatively conveyed first bag film 100 and the second bag film 200, so that the relatively conveyed first bag film 100 and the second bag film 200 bend synchronously around the width direction and enter the sealing channel 4101 synchronously. That is, the sealing channel 4101 is used to enter the relatively conveyed first bag film 100 and the second bag film 200, the relatively conveyed first bag film 100 and the second bag film 200 are located in the extension direction of one end of the sealing channel 4101, and the film guiding assembly 20 is located entirely in the extension direction of one end of the sealing channel 4101.

[0044] The pressure sealing unit 42 is positioned in the overall conveying direction of the first bag film 100 and the second bag film 200 entering the sealing channel 4101. The pressure sealing unit 42 is used to partially heat-melt weld the first bag film 100 and the second bag film 200 as they pass through the sealing channel 4101, so as to form at least one filling bag body 300 having a filling port. At least one of the filling ends is positioned to correspond to the filling port of at least one filling bag body 300, such that it extends into the sealing channel 4101 and is located between the first bag film 100 and the second bag film 200. A predetermined dose of liquid is injected into the filling bag body 300 through the filling port via the at least one filling end. After the predetermined dose of liquid has been injected into the at least one filling bag body 300, the portions of the first bag film 100 and the second bag film 200 located at the corresponding filling ports are heat-fused by the pressure sealing unit 42 to seal the filling ports of at least one filling bag body 300.

[0045] The compression-cutting unit 43 is positioned in the direction along which at least one of the filling bags 300, after the filling opening is closed, is conveyed along the sealing channel 4101. The compression-cutting unit 43 is used to cut along the circumference of at least one of the filling bags 300 after the filling opening is closed as it passes by, so as to partially adhere at least one of the filling bags 300 after the filling opening is closed to the remaining first bag film 100 and the remaining second bag film 200, and then convey the at least one filling bag 300 cut along the circumference out of the sealing channel 4101 together with the remaining first bag film 100 and the remaining second bag film 200.

[0046] The bag-removing assembly 50 is positioned in the conveying direction of at least one of the filling bags 300, which is circumferentially cut and conveyed out from the sealing channel 4101. The bag-removing assembly 50 is used to separate the corresponding at least one of the filling bags 300 from the remaining first bag film 100 and the remaining second bag film 200.

[0047] The receiving assembly 60 includes a receiving mounting member 61, a receiving belt shaft 62, a receiving drive member 63, and a receiving component 64. The receiving mounting member 61 is located near the mounting frame 11. The receiving belt shaft 62 is rotatably mounted on the receiving mounting member 61. The axial direction of the receiving belt shaft 62 is parallel to the width direction of the remaining first bag films 100 and the remaining second bag films 200 that are jointly conveyed after separating at least one of the corresponding filling bag bodies 300. The receiving drive member 63 is mounted on the receiving mounting member 61. The receiving belt shaft 62 is connected to the output end of the receiving drive member 63 in a manner that allows it to be driven by the receiving drive member 63. The receiving component 64 includes an axial receiving portion 641 and two receiving limiting portions 642. The axial take-up portion 641 is held in place on the take-up belt shaft 62 in a manner that allows it to be rotated. The axial take-up portion 641 is used to wind up the remaining first bag film 100 and the remaining second bag film 200 that are separated from and jointly transported by at least one of the corresponding filling bag bodies 300. Two take-up limiting portions 642 are respectively connected to the two ends of the axial take-up portion 641 in the axial direction, respectively, in a manner that allows them to be passed through the take-up belt shaft 62. The radial dimensions of the two take-up limiting portions 642 are larger than the radial dimension of the axial take-up portion 641, so as to restrict the movement of the remaining first bag film 100 and the remaining second bag film 200 along the axial direction of the axial take-up portion 641 when the axial take-up portion 641 winds up the jointly transported remaining first bag film 100 and the remaining second bag film 200, thereby preventing axial deviation.

[0048] It is worth mentioning that, since the axial receiving part 641 winds up the remaining first bag film 100 and the remaining second bag film 200 that are being transported together, it prevents the remaining first bag film 100 and the remaining second bag film 200 that are being transported together from piling up in a scattered state near the mounting frame 11. This reduces the difficulty of manually collecting and transporting the remaining first bag film 100 and the remaining second bag film 200 that are being transported together, and improves the efficiency of manually collecting and transporting the remaining first bag film 100 and the remaining second bag film 200 that are being transported together.

[0049] It should be noted that one end of the take-up belt shaft 62 passes through the take-up mounting member 61, and a bearing is fitted on the take-up belt shaft 62 at the point where it passes through the take-up mounting member 61 to prevent friction between the take-up belt shaft 62 and the take-up mounting member 61 when the take-up belt shaft 62 is driven by the output end of the take-up drive member 63.

[0050] Preferably, the take-up belt shaft 62 has at least one axial groove 6201 along its axial direction. The axial take-up portion 641 has at least one axial protrusion 6411 adapted to the at least one axial groove 6201. That is, when the axial take-up portion 641 is sleeved on the take-up belt shaft 62, the at least one axial protrusion 6411 of the axial take-up portion 641 remains inserted into the at least one axial groove 6201 of the take-up belt shaft 62, so that when the take-up belt shaft 62 is driven by the take-up drive member 63, the take-up belt shaft 62 rotates the axial take-up portion 641 through the axial protrusion 6411 of the axial take-up portion 641, thereby smoothly winding up the remaining first bag film 100 and the remaining second bag film 200 that are jointly conveyed by the axial take-up portion 641.

[0051] It is understood that when the axial take-up part 641 is rotated by the take-up belt shaft 62, the two take-up limiting parts 642 will be driven to rotate synchronously.

[0052] Preferably, the take-up assembly 60 further includes at least one pair of axial limiting members 65. Each pair of axial limiting members 65 includes a limiting mounting member 651 and a limiting fixing member 652. The at least one pair of limiting mounting members 651 are movably disposed at both ends of the axial take-up portion 641 in the axial direction of the axial direction, respectively, so as to be held through the take-up belt shaft 62, and each pair of limiting mounting members 651 remains abutting against the pair of take-up limiting portions 642. At least one pair of the limiting fasteners 652 are respectively threaded through at least one pair of the limiting mounting members 651, and at least one pair of the limiting fasteners 652 are respectively inserted into the axial groove 6201 and pressed against the inner wall of the axial groove 6201, so as to fix at least one pair of the limiting mounting members 651 respectively by at least one pair of the limiting fasteners 652, so that at least one pair of the limiting mounting members 651 are respectively kept against the pair of take-up limiting parts 642. In this way, the setting of at least one pair of the limiting mounting members 651 prevents the axial take-up part 641 and the two take-up limiting parts 642 from moving as a whole along the axial direction of the take-up belt shaft 62, so as to prevent the axial take-up part 641 and the two take-up limiting parts 642 from disengaging from the take-up belt shaft 62 as a whole along the axial direction of the take-up belt shaft 62.

[0053] More preferably, the take-up belt shaft 62 is further provided with at least one pair of radial holes that communicate with the axial groove 6201. Each of the at least one pair of radial holes corresponds to a point where each of the at least one pair of limiting and fixing members 652 presses against the inner wall of the axial groove 6201. Each of the at least one pair of radial holes is used for insertion of the at least one pair of limiting and fixing members 652.

[0054] In other words, when at least one pair of the limiting fasteners 652 are respectively inserted into the axial groove 6201, the stability of at least one pair of the limiting fasteners 652 being fixed by the corresponding radial holes can be improved by further inserting them into the corresponding radial holes. This ensures that the axial take-up portion 641 and the two take-up limiting portions 642 are stably limited to their positions along the axis of the take-up belt shaft 62, preventing the remaining first bag film 100 and the remaining second bag film 200 that are being wound by the axial take-up portion 641 from shifting axially due to the movement of the axial take-up portion 641 and the two take-up limiting portions 642 along the axis of the take-up belt shaft 62.

[0055] Specifically, at least one pair of the limiting fasteners 652 are respectively threadedly connected to the inner wall of the corresponding radial hole.

[0056] As an example, the receiving drive 63 is implemented to include a drive motor. At least one pair of the limiting fasteners 652 are each implemented to include screws.

[0057] Preferably, the take-up assembly 60 further includes a plurality of feed rollers 66. The plurality of feed rollers 66 are rotatably mounted on the take-up mounting member 61 with their axial directions parallel to the axial direction of the take-up belt shaft 62. The plurality of feed rollers 66 are respectively used to wrap around and guide the remaining first bag film 100 and the remaining second bag film 200 that are being conveyed together, so that the remaining first bag film 100 and the remaining second bag film 200 are stably conveyed to the axial take-up section 641 and wound up by the axial take-up section 641.

[0058] In this embodiment, the receiving mounting component 61 is connected to the mounting frame 11.

[0059] Specifically, the two receiving restricting parts 642 are each provided with a plurality of corresponding through holes 64201 evenly distributed along the circumference, so as to reduce the mass of the two receiving restricting parts 642 by providing the plurality of through holes 64201, thereby reducing the load on the receiving belt shaft 62.

[0060] It is understood that after the axial take-up portion 641 of the take-up member 64 completes the winding of the remaining first bag film 100 and the remaining second bag film 200, and after the axial take-up portion 641 and the two take-up restriction portions 642 are removed from the take-up belt shaft 62 as a whole, the axial take-up portion 641 and the two take-up restriction portions 642, which are wound with the remaining first bag film 100 and the remaining second bag film 200, can be moved as a whole by inserting a forklift rod into at least one of the through holes 64201 of the two take-up restriction portions 642.

[0061] Preferably, at least one pair of the limiting mounting members 651 extend partially into the axial groove 6201 to form an inner protrusion 6511. The inner protrusions 6511 of the at least one pair of limiting mounting members 651 are respectively adapted to the axial groove 6201. In other words, the inner protrusions 6511 of the at least one pair of limiting mounting members 651 remain in contact with the inner wall of the axial groove 6201, so that by forming the inner protrusions 6511 of the at least one pair of limiting mounting members 651, when the at least one pair of limiting mounting members 651 are fixed by the at least one pair of limiting fasteners 652, the degree of shaking of the at least one pair of limiting mounting members 651 on the surface of the take-up belt shaft 62 is reduced, thereby improving the stability of the at least one pair of limiting mounting members 651.

[0062] It is understood that in this embodiment, when at least one pair of the limiting fasteners 652 are inserted into the axial groove 6201 and the corresponding radial hole respectively, at least one pair of the limiting fasteners 652 will respectively penetrate the inner protrusion 6511 of the corresponding limiting mounting member 651.

[0063] Preferably, the first bag film 100 and the second bag film 200, which are sleeved on the film feeding roller 121, are integrally formed along the width direction. In other words, the first bag film 100 and the second bag film 200, which are sleeved on the film feeding roller 121, are spliced ​​together as a whole along the width direction so that the integrally formed first bag film 100 and second bag film 200 are released together when the film feeding roller 121 rotates.

[0064] It is understood that the film feeding roller 121 can be driven by a drive motor.

[0065] The film-feeding assembly 20 includes a slitting member 21 and a pair of applicator units 22. The slitting member 21 includes a slitting mounting unit 211 and a slitting piece 212. The slitting piece 212 is disposed on the mounting frame 11 via the slitting mounting unit 211, and the slitting piece 212 is held between the integrally formed first bag film 100 and the second bag film 200, which are released together from the film-feeding roller 121, in the width direction, so as to slit the first bag film 100 and the second bag film 200 as they pass through the slitting piece 212. A pair of guiding units 22 are respectively positioned in the conveying direction of the first bag film 100 and the second bag film 200 after being cut by the slitting member 212, in a relative manner. The pair of guiding units 22 are used to guide the first bag film 100 and the second bag film 200 cut by the slitting member 212 from the same direction conveying state to the opposite conveying state and synchronously enter the sealing channel 4101.

[0066] It should be noted that when the first bag film 100 and the second bag film 200 entering the sealing channel 4101 are partially heat-fused by the pressure sealing unit 42 to form at least one filling bag 300, packaging information needs to be printed on the surface of the at least one filling bag 300. To improve the efficiency of printing packaging information on the corresponding filling bag 300 surface, packaging information is pre-printed on the surfaces of the first bag film 100 and the second bag film 200 sleeved on the film feeding roller 121, so that when the first bag film 100 and the second bag film 200 entering the sealing channel 4101 are partially heat-fused by the pressure sealing unit 42 to form at least one filling bag 300, the packaging information is directly formed on the surface of the filling bag 300.

[0067] Since the first bag film 100 and the second bag film 200 are made as a single piece, packaging information can be printed on the surfaces of the first bag film 100 and the second bag film 200 simultaneously, thereby improving the efficiency of printing packaging information on the surfaces of the first bag film 100 and the second bag film 200.

[0068] Further, the slitting and mounting unit 211 includes a slitting mounting member 2111, a slitting extension member 2112, and a slitting fixing member 2113. The slitting mounting member 2111 is mounted on the mounting frame 11. The slitting extension member 2112 is movably inserted through the slitting mounting member 2111 in a direction parallel to the axis of the film feeding roller 121. The slitting member 212 is disposed at the end of the slitting extension member 2112. The slitting fastener 2113 is movably inserted into the slitting mounting member 2111 in such a way that it is threadedly connected to the slitting mounting member 2111, and the slitting fastener 2113 is held to press against the corresponding slitting extension 2112 through the slitting mounting member 2111, so that the slitting extension 2112 is fixed to the slitting mounting member 2111 by the slitting fastener 2113, thereby keeping the slitting member 212 between the first bag film 100 and the second bag film 200 integrally formed and released together from the film feeding roller 121 in the width direction.

[0069] As an example, the slitting member 212 is implemented to include a blade. The slitting member 212 is fixed to the slitting extension 2112 of the slitting mounting unit 211 by screws for replacement when the slitting member 212 becomes dull. The slitting fixing member 2113 is implemented to include screws.

[0070] Understandably, when the position of the slitting member 212 needs to be adjusted, the slitting fixing member 2113 is first rotated to move it away from the corresponding slitting extension member 2112. Then, the slitting extension member 2112 is moved along the extension direction while still penetrating the slitting mounting member 2111, thereby moving the slitting member 212 disposed on the slitting extension member 2112, thus achieving the adjustment of the position of the slitting member 212. Furthermore, after adjusting the position of the slitting member 212 by moving the slitting extension member 2112, the slitting fixing member 2113 can be rotated again to keep it pressed against the corresponding slitting extension member 2112 at the point where it penetrates the slitting mounting member 2111, thereby fixing the position of the slitting member 212.

[0071] Preferably, each pair of the applicator units 22 includes a first applicator roller 221 and a second applicator roller 222. Both the first applicator rollers 221 and the second applicator rollers 222 are positioned along the extension direction of one end of the sealing channel 4101. The first applicator rollers 221 are positioned relative to each other on the mounting frame 11 and are respectively located in the same direction of conveying the first bag film 100 and the second bag film 200. One end of each pair of first applicator rollers 221 is close to the slitting member 212. The other ends of each pair of first applicator rollers 221 are offset away from each other along the same direction of conveying the first bag film 100 and the second bag film 200. The pair of first applicator rollers 221 remain perpendicular to each other. In other words, the pair of first applicator rollers 221 are offset away from each other by 45 degrees along the same direction of conveying the first bag film 100 and the second bag film 200, respectively, in a relative manner. A pair of first guide rollers 221 are respectively used to abut against the first bag film 100 and the second bag film 200 cut by the slitting member 212. A pair of second guide rollers 222 are respectively arranged in a relative manner in the conveying direction of the first bag film 100 and the second bag film 200 that abut against the pair of first guide rollers 221. The axial direction of the pair of second guide rollers 222 is perpendicular to the axial direction of the film feeding roller 121. The pair of second guide rollers 222 are respectively used to abut against the first bag film 100 and the second bag film 200 that have passed through the pair of first guide rollers 221. That is, the first bag film 100 and the second bag film 200 conveyed to the pair of first guide rollers 221 will abut against the pair of first guide rollers 221 and the pair of second guide rollers 222 in sequence.

[0072] It is understood that, due to the arrangement of the pair of first guide rollers 221, the first bag film 100 and the second bag film 200, which are cut by the slitting member 212, will be conveyed in opposite directions and guided to separate by passing over the pair of slitting members 212, respectively, in a direction perpendicular to the same direction of conveying the first bag film 100 and the second bag film 200. At the same time, the first bag film 100 and the second bag film 200, which are conveyed in opposite directions, will be conveyed relative to each other by passing over the pair of second guide rollers 222 respectively.

[0073] Furthermore, since the extension direction of one end of the sealing channel 4101 is located between the first bag film 100 and the second bag film 200 being transported relative to each other, when the first bag film 100 and the second bag film 200 being transported relative to each other approach the sealing channel 4101, by simultaneously bending the first bag film 100 and the second bag film 200 being transported relative to each other around the width direction, the first bag film 100 and the second bag film 200 being transported relative to each other can be simultaneously entered into the sealing channel 4101.

[0074] It is understood that packaging information is printed on predetermined positions on the surfaces of the first bag film 100 and the second bag film 200, respectively, so that when the first bag film 100 and the second bag film 200 are synchronously conveyed and enter the sealing channel 4101 and are partially welded by the pressure sealing unit 42 to form the corresponding filling bag body 300, the packaging information at the predetermined positions on the surfaces of the first bag film 100 and the second bag film 200 are respectively located on the surface of the corresponding filling bag body 300.

[0075] Preferably, the mounting frame 11 has two pairs of adjustable guide grooves 1101. The two pairs of adjustable guide grooves 1101 are respectively located at both ends of a pair of second guide rollers 222, and both pairs of adjustable guide grooves 1101 extend along the direction of relative conveying of the first bag film 100 and the second bag film 200. The film-feeding assembly 20 also includes two pairs of adjustable members 23. Each pair of adjustable members 23 includes an adjustable sliding member 231 and an adjustable driving member 232. The two pairs of adjustable sliding members 231 are respectively disposed in the two pairs of adjustable guide grooves 1101 in a manner that allows them to slide along the extension direction of the two pairs of adjustable guide grooves 1101. The two pairs of adjustable driving members 232 are respectively kept extending along the extension direction of the corresponding two pairs of adjustable guide grooves 1101, and the two pairs of adjustable driving members 232 are respectively kept threadedly connected to the mounting frame 11 and inserted into the corresponding two pairs of adjustable guide grooves 1101. One end of each of the two adjusting drive members 232 is connected to a corresponding pair of adjusting sliding members 231. A pair of second guide rollers 222 are rotatably disposed between the two pairs of adjusting sliding members 231.

[0076] Preferably, both pairs of the adjusting drive members 232 are implemented with bolts. Both pairs of the adjusting slider members 231 are implemented with sliders.

[0077] As an example, by rotating one of the pair of adjustment actuators 232, one of the pair of adjustment sliders 231 can be driven to slide along the extending direction of one of the pair of adjustment guide grooves 1101, thereby driving one of the second guide rollers 222 to move along the direction of relative conveying of the first bag film 100 and the second bag film 200. Since the first bag film 100 and the second bag film 200 respectively pass over the pair of second guide rollers 222 and enter the sealing channel 4101, the degree of synchronization of the first bag film 100 and the second bag film 200 entering the sealing channel 4101 will change when one of the second guide rollers 222 moves along the direction of relative conveying of the first bag film 100 and the second bag film 200.

[0078] Therefore, when the first bag film 100 and the second bag film 200, which are being conveyed relative to each other, simultaneously enter the sealing channel 4101 and are partially welded by the pressure sealing unit 42 to form the corresponding filling bag body 300, and the packaging information at the predetermined position on the surface of the first bag film 100 and the second bag film 200 is not correspondingly located on the surface of the filling bag body 300, at least one second guide roller 222 can be moved along the direction of relative conveying of the first bag film 100 and the second bag film 200, thereby changing the degree of synchronization of the first bag film 100 and the second bag film 200 entering the sealing channel 4101, so that the packaging information at the predetermined position on the surface of the first bag film 100 and the second bag film 200 is correspondingly located on the surface of the filling bag body 300.

[0079] Preferably, the filling assembly 30 includes at least one liquid-containing element 31 and at least one suction member 32 corresponding to the at least one liquid-containing element 31. The at least one liquid-containing element 31 is located near the mounting frame 11. The at least one suction member 32 includes a suction tube 321, a suction element 322, and a dispensing unit 323. The at least one suction element 322 is in communication with the liquid-containing element 31 through the corresponding suction tube 321. The at least one dispensing unit 323 is connected to the corresponding suction element 322, and the at least one dispensing unit 323 has a corresponding filling end, so that after the at least one suction element 322 draws out a predetermined dose of liquid from the corresponding liquid-containing element 31 through the corresponding suction tube 321, the predetermined dose of liquid is ejected through the filling end of the corresponding dispensing unit 323.

[0080] As an example, the pumping component 322 is implemented to include a suction pump.

[0081] More preferably, the filling assembly 30 further includes a filling fixing member 33. The filling fixing member 33 is mounted on the mounting frame 11 and has at least one through hole corresponding to at least one of the filling ends. At least one of the dispensing units 323 is partially placed in the filling fixing member 33 such that the filling end remains through the corresponding through hole to improve the stability of the filling end of the dispensing unit 323. The filling end of at least one dispensing unit 323 is positioned to correspond to the filling port of at least one filling bag 300 such that it remains inserted into the sealing channel 4101 and located between the first bag film 100 and the second bag film 200.

[0082] Specifically, the pressure sealing unit 42 includes a sealing drive 421, a first sealing pressure plate 422, and a second sealing pressure plate 423. The sealing drive 421 is mounted on the sealing mounting bracket 41, and the extension / retraction direction of the output end of the sealing drive 421 is perpendicular to the surface of the first bag film 100 entering the sealing channel 4101. The first sealing pressure plate 422 and the second sealing pressure plate 423 are positioned opposite each other on both sides of the first bag film 100 and the second bag film 200 entering the sealing channel 4101. The first sealing pressure plate 422 is positioned at the output end of the sealing drive 421 to maintain a predetermined temperature. The second sealing pressure plate 423 is mounted on the sealing mounting bracket 41. The second sealing plate 423 forms at least two vertical sealing members 4231 and at least one horizontal sealing member 4232 protruding from the first sealing plate 422. The at least two vertical sealing members 4231 extend in a direction parallel to the sealing channel 4101. The at least one horizontal sealing member 4232 extends in a direction perpendicular to the sealing channel 4101. At least two of the vertical pressing members 4231 intersect with at least one of the horizontal pressing members 4232 to form a filling pressing port 42301 between adjacent vertical pressing members 4231. Then, when the first sealing pressing plate 422 is brought to the second sealing pressing plate 423 by the sealing driving member 421, the first bag film 100 and the second bag film 200 are heat-fused and welded at the locations corresponding to at least two of the vertical pressing members 4231 and at least one of the horizontal pressing members 4232 through the first sealing pressing plate 422 to form at least one corresponding filling bag body 300, and the filling port of the filling bag body 300 is formed at the corresponding filling pressing port 42301. The filling end of at least one of the liquid dispensing units 323 is kept in the extension direction of the output end of the sealing drive 421 and is aligned with the filling pressure port 42301 so that the filling end of at least one of the liquid dispensing units 323 is aligned with the filling port of the filling bag body 300, thereby injecting a predetermined dose of liquid into the corresponding filling bag body 300 through the filling port via the filling end of at least one of the liquid dispensing units 323.

[0083] It is understood that after a predetermined dose of liquid is injected into at least one of the filling bag bodies 300, the first bag film 100 and the second bag film 200 will synchronously re-enter the sealing channel 4101, thereby driving the filling bag body 300 formed by the heat fusion welding of a portion of the first bag film 100 and the second bag film 200 along the sealing channel 4101, and causing the filling port of the corresponding filling bag body 300 filled with the predetermined dose of liquid to correspond with the transverse pressing member 4232, thereby sealing the bag body. When the sealing drive member 421 brings the plate 422 to the second sealing pressure plate 423 again, the filling port of the corresponding filling bag body 300 is sealed by the first sealing pressure plate 422 and the horizontal pressure member 4232. At the same time, the first sealing pressure plate 422 heat-melt welds the first bag film 100 and the second bag film 200 at at least two of the vertical pressure members 4231 and at least one of the horizontal pressure members 4232 to form the next filling bag body 300 with the filling port.

[0084] Furthermore, after the filling port of the filling bag 300 is sealed, the first bag film 100 and the second bag film 200 will enter the sealing channel 4101 again synchronously, so as to drive the filling bag 300, which is formed by the hot-melt welding of part of the first bag film 100 and the second bag film 200 after sealing the filling port, to move along the sealing channel 4101.

[0085] As an example, the bag-sealing drive 421 is implemented including a telescopic cylinder. The predetermined temperature of the surface of the first bag-sealing pressure plate 422 is not lower than the melting point temperature of the first bag film 100 and / or the second bag film 200.

[0086] Preferably, the bag-cutting unit 43 includes a bag-cutting drive 431, a first bag-cutting pressure plate 432, and a second bag-cutting pressure plate 433. Both the bag-cutting drive 431 and the second bag-cutting pressure plate 433 are mounted on the bag-sealing mounting frame 41. The extension / retraction direction of the output end of the bag-cutting drive 431 is perpendicular to the surface of the first bag film 100 entering the bag-sealing channel 4101. The first bag-cutting pressure plate 432 and the second bag-cutting pressure plate 433 are positioned relative to each other on both sides of the filling bag body 300 after the filling port is closed, moving along the bag-sealing channel 4101. A plurality of cutting elements are mounted on the end face of the first bag-cutting pressure plate 432 facing the second bag-cutting pressure plate 433. Several cutting elements are positioned along the extension and retraction direction of the output end of the bag cutting drive 431 to maintain a circumferential arrangement corresponding to the periphery of the filling bag body 300 after the filling port is closed. When the first bag cutting pressure plate 432 is brought to the second bag cutting pressure plate 433 by the bag cutting drive 431, the periphery of the filling bag body 300 after the filling port is closed is cut by the several cutting elements on the first bag cutting pressure plate 432, thereby cutting the filling bag body 300 after the filling port is closed to the remaining first bag film 100 and the remaining second bag film 200 to a partially adhered state.

[0087] It should be noted that after the periphery of the filling bag 300 corresponding to the sealed filling port is cut, the periphery of the filling bag 300 will remain partially adhered to the remaining first bag film 100 and the remaining second bag film 200, so as to form several break points between the filling bag 300 and the remaining first bag film 100 and the remaining second bag film 200. At the same time, the filling bag 300 whose periphery has been cut will be sent out of the sealing channel 4101 along with the first bag film 100 and the second bag film 200 that continuously enter the sealing channel 4101.

[0088] As an example, several of the cutting elements are implemented including blades. The bag-cutting drive 431 is implemented including a telescopic cylinder.

[0089] Preferably, the bag-sealing and cutting assembly 40 further includes a film-coated member 44. The film-coated member 44 includes a pair of film-coated rolling elements 441 and a pair of film-coated driving elements 442. The pair of film-coated rolling elements 441 are rotatably disposed on both sides of the bag-sealing channel 4101 in a relative manner. The pair of film-coated rolling elements 441 extend along a direction perpendicular to the extension of the bag-sealing channel 4101, and are respectively pressed against the first bag film 100 and the second bag film 200 entering the bag-sealing channel 4101. The pair of film-coated driving elements 442 are respectively mounted on the bag-sealing mounting bracket 41, and the pair of film-coated rolling elements 441 are respectively disposed at the output ends of the pair of film-coated driving elements 442, so as to drive the film-coated rolling elements 441 respectively by the pair of film-coated driving elements 442.

[0090] It is understood that the pair of film-driven rotating members 442 rotate in opposite directions when they drive the pair of film-rolling members 441 respectively. Since the pair of film-rolling members 441 are respectively pressed against the first bag film 100 and the second bag film 200 entering the sealing channel 4101, during the process of the pair of film-driven rotating members 442 driving the pair of film-rolling members 441 respectively, the first bag film 100 and the second bag film 200 entering the sealing channel 4101 are driven to be conveyed along the sealing channel 4101, thereby continuously driving the relatively conveyed first bag film 100 and second bag film 200 into the sealing channel 4101, and driving the partially cut and adhered filling bag body 300 out of the sealing channel 4101. At the same time, when a pair of film-coated rolling elements 441 are driven to rotate by a pair of film-coated driving elements 442 respectively, the corresponding filling bag 300 that closes the filling port will be sent between the first bag cutting and pressing plate 432 and the second bag cutting and pressing plate 433.

[0091] Each pair of the film-coated rolling elements 441 includes rollers. Each pair of the film-coated rotating elements 442 includes a drive motor.

[0092] It is understood that by driving a pair of film-coated rotating members 442 to rotate a pair of film-coated rolling members 441 a predetermined number of times, the first bag film 100 and the second bag film 200 entering the sealing channel 4101 can travel a predetermined distance.

[0093] In this embodiment, a pair of film-coated rolling elements 441 are respectively positioned in the conveying direction after the corresponding filling bag body 300 is formed by partial hot-melt welding of the first bag film 100 and the second bag film 200 and the filling port is closed. The pair of film-coated rolling elements 441 extend radially along their respective extension directions to form at least two pressing portions 4411. Each of the at least two pressing portions 4411 of the film-coated rolling elements 441 corresponds to at least two vertical pressing elements 4231, thereby pressing the at least two pressing portions 4411 of the film-coated rolling elements 441 against the areas of the first bag film 100 and the second bag film 200 that are not formed into the filling bag body 300, preventing the at least two pressing portions 4411 of the film-coated rolling elements 441 from crushing the corresponding filling bag body 300.

[0094] It is understood that when a pair of film-coated rolling elements 441 are driven by a pair of film-coated driving elements 442 respectively, the first bag film 100 and the second bag film 200 entering the sealing channel 4101 will be pulled to tighten, thereby preventing the corresponding filling bag body 300, which is partially heat-melted welded from the first bag film 100 and the second bag film 200, from wrinkling due to looseness.

[0095] Furthermore, the bag-sealing and cutting assembly 40 also includes an information printing unit 45. The information printing unit 45 includes an information printing drive 451, a first information pressing plate 452, and a second information pressing plate 453. The information printing drive 451 and the second information pressing plate 453 are both disposed on the bag-sealing mounting frame 41, and the extension / retraction direction of the output end of the information printing drive 451 is perpendicular to the surface of the first bag film 100 entering the bag-sealing channel 4101. The first information pressing plate 452 and the second information pressing plate 453 are disposed on both sides of the filling bag body 300 after the filling port is closed, moving along the bag-sealing channel 4101, in a relatively opposite manner. The first information pressing plate 452 is disposed at the output end of the information printing drive 451 to maintain a predetermined temperature. The second sealing film plate 423 is fitted with several protrusions protruding towards the first information film plate 452, so that when the first information film plate 452 is brought toward the second information film plate 453 by the information printing drive 451, the first information film plate 452 presses the predetermined position of the periphery of the filling bag body 300 after the filling port is closed against the several protrusions on the second information film plate 453, so that the shape corresponding to the several protrusions is heat-melted at the predetermined position of the periphery of the filling bag body 300 after the filling port is closed.

[0096] It should be noted that the first information pressing plate 452 can press the predetermined position of the periphery of the filling bag 300 after the filling port is closed against a plurality of protrusions on the second information pressing plate 453, so that the production date information and / or expiration date information and / or production batch number information and / or QR code information of the liquid in the filling bag 300 can be heat-melted out by the plurality of protrusions at the predetermined position of the periphery of the filling bag 300 after the filling port is closed.

[0097] It is understood that after the shape corresponding to the plurality of protrusions is heat-melted at a predetermined position on the periphery of the filling bag body 300 after the filling port is closed, a pair of film-carrying drive members 442 will drive a pair of film-carrying rolling members 441 respectively, so that when the first bag-cutting pressure plate 432 is brought to the second bag-cutting pressure plate 433 by the bag-cutting drive member 431, the periphery of the filling bag body 300 after the filling port is closed is cut by the plurality of cutting members on the first bag-cutting pressure plate 432, thereby cutting the filling bag body 300 after the filling port is closed and the remaining first bag film 100 and the remaining second bag film 200 to a partially adhered state.

[0098] Specifically, the bag-sealing mounting frame 41 has at least one pair of guide rollers 46. At least one pair of guide rollers 46 are rotatably disposed on the bag-sealing mounting frame 41, and are positioned on both sides of the end of the bag-sealing channel 4101 in a relative-to-relative conveying direction along the first bag film 100 and the second bag film 200. The at least one pair of guide rollers 46 are respectively used to wrap around the first bag film 100 and the second bag film 200 as they are conveyed relative to each other and enter the bag-sealing channel 4101, thereby improving the smoothness of the first bag film 100 and the second bag film 200 as they enter the bag-sealing channel 4101.

[0099] Preferably, the bag-taking assembly 50 includes at least one bag-taking adsorption unit 51, one bag-taking moving unit 52, and one bag-taking stop bar 53. At least one bag-taking adsorption unit 51 corresponds to at least one circumferentially cut filling bag 300 conveyed from the sealing channel 4101. At least one bag-taking adsorption unit 51 includes an adsorption connecting rod 511 and an adsorption element 512. The adsorption element 512 is mounted on one end of the adsorption connecting rod 511 and has a negative pressure space. The adsorption connecting rod 511 has an air extraction channel along its axis that communicates with the negative pressure space. The negative pressure space of the adsorption element 512 of at least one bag-taking adsorption unit 51 faces the surface of the at least one circumferentially cut filling bag 300 conveyed from the sealing channel 4101. The bag-taking moving unit 52 is disposed on the mounting frame 11. At least one of the adsorption connecting rods 511 is disposed on the bag-taking moving unit 52 in such a way that it can be moved along the direction of the negative pressure space of the adsorption member 512 by being driven by the bag-taking moving unit 52, so that the bag-taking moving unit 52 drives the corresponding adsorption member 512 to approach and adsorb the corresponding filling bag body 300 that has been cut around the perimeter and is conveyed from the sealing channel 4101 by the bag-taking moving unit 52 through at least one adsorption connecting rod 511. When the filling bag body 300 adsorbed by the corresponding adsorption member 512 is moved away from the remaining first bag film 100 and the remaining second bag film 200 by the bag-taking moving unit 52 through at least one adsorption connecting rod 511, the filling bag body 300 is taken away from the remaining first bag film 100 and the remaining second bag film 200. The bag-removing stop bar 53 is disposed on the mounting frame 11, and the bag-removing stop bar 53 is disposed on the path on which the adsorption member 512 adsorbs and drives the corresponding filling bag 300 to move away from the remaining first bag film 100 and the remaining second bag film 200.

[0100] It is understood that when the bag-taking moving unit 52 moves the corresponding adsorption member 512 close to the corresponding filling bag body 300 through at least one of the adsorption connecting rods 511, the gas in the negative pressure space will be drawn out from the air extraction channel by a suction member (such as an air pump), and then the corresponding filling bag body 300 will be adsorbed by the adsorption member 512.

[0101] Furthermore, during the process of the bag-taking moving unit 52 driving the corresponding filling bag 300 adsorbed by the adsorption member 512 to move away from the remaining first bag films 100 and the remaining second bag films 200 via at least one of the adsorption connecting rods 511, the suction member (such as an air pump) will stop sucking air from the negative pressure space through the air suction channel, so as to loosen the adsorption member 512 and the corresponding filling bag 300. At the same time, when the adsorption member 512 adsorbs and drives the corresponding filling bag 300 to move away from the remaining first bag films 100 and the remaining second bag films 200, the filling bag 300 adsorbed by the adsorption member 512 will break at several break points with the remaining first bag films 100 and the remaining second bag films 200, thereby separating the corresponding filling bag 300 from the remaining first bag films 100 and the remaining second bag films 200.

[0102] Specifically, when the filling bag 300 adsorbed by the adsorbent 512 becomes stuck to the adsorbent 512, the filling bag 300 adsorbed and stuck to the adsorbent 512 will fall off due to impact with the bag-removing stop bar 53, thereby preventing the filling bag 300 from failing to fall off due to adhesion between the adsorbent 512 and the corresponding filling bag 300. Conversely, when the filling bag 300 adsorbed by the adsorbent 512 is not stuck to the adsorbent 512, the filling bag 300 can fall off naturally when the suction device (such as an air pump) stops sucking air from the negative pressure space through the air suction channel.

[0103] In this embodiment, since the first bag film 100 and the second bag film 200 are fitted onto the film feeding roller 121, the width directions of both the first bag film 100 and the second bag film 200, which are released from the film feeding roller 121 before passing through the film guiding assembly 20, are parallel to the axial direction of the film feeding roller 121. The direction in which the first bag film 100 and the second bag film 200 are conveyed in the same direction from the film feeding roller 121 is perpendicular to the axial direction of the film feeding roller 121.

[0104] As an example, at least one of the said adsorption elements 512 is implemented including a suction cup.

[0105] Preferably, the bag-retrieving moving unit 52 includes a bag-retrieving driving component 521, a bag-retrieving actuating component 522, and at least one bag-retrieving mounting unit 523 corresponding to the adsorption connecting rod 511. The bag-retrieving driving component 521 is mounted on the mounting frame 11. The extension and retraction direction of the output end of the bag-retrieving driving component 521 is the direction in which the negative pressure space of the adsorption component 512 faces. The bag-retrieving actuating component 522 is mounted on the output end of the bag-retrieving driving component 521. The adsorption connecting rod 511 is mounted to the bag-retrieving actuating component 522 via the bag-retrieving mounting unit 523.

[0106] More preferably, the bag-removing mounting unit 523 includes a bag-removing mounting member 5231 and a mounting fastener 5232. The bag-removing mounting member 5231 is disposed on the bag-removing driving member 522, and the bag-removing mounting member 5231 is movably penetrated by the corresponding adsorption connecting rod 511. The mounting fastener 5232 is movably inserted into the bag-removing mounting member 5231 in a threaded connection manner, and the mounting fastener 5232 is pressed against the corresponding adsorption connecting rod 511 penetrating the bag-removing mounting member 5231, so as to fix the corresponding adsorption connecting rod 511 to the bag-removing mounting member 5231 by means of the mounting fastener 5232.

[0107] It is understood that when the output end of the bag-taking drive 521 extends or retracts, the bag-taking drive 521 will sequentially drive the corresponding adsorption member 512 to approach and move away from the corresponding filling bag body 300 through the bag-taking drive member 522, the bag-taking mounting member 5231 and the corresponding adsorption connecting rod 511.

[0108] As an example, the bag-retrieving drive 521 is implemented including a telescopic cylinder. The mounting fastener 5232 is implemented including screws.

[0109] Preferably, the bag-retrieving assembly 50 further includes a bag-retrieving conveyor 54. The bag-retrieving conveyor 54 is positioned below the corresponding filling bag 300 adsorbed by the adsorption member 512. The extending direction of the bag-retrieving conveyor 54 is parallel to the direction in which the adsorption member 512 adsorbs and moves the corresponding filling bag 300, so as to catch the filling bag 300 that has fallen after being adsorbed by the adsorption member 512.

[0110] It is understandable that, since the extension direction of the bag-taking conveyor 54 is parallel to the direction in which the adsorption member 512 adsorbs and drives the corresponding filling bag 300 to move, it can promptly catch the filling bag 300 that falls due to impact with the bag-taking stop bar 53, and at the same time promptly catch the filling bag 300 that has not adhered to the adsorption member 512 and has fallen, the bag-taking conveyor 54 prevents the corresponding filling bag 300 adsorbed by the adsorption member 512 from falling to the ground and getting dirty.

[0111] As an example, in this embodiment, the bag-taking conveyor 54 is implemented to include a conveyor belt.

[0112] It should be noted that the end of the bag-taking conveyor 54 away from the bag-taking stop bar 53 may be provided with a storage box to collect each of the filling bags 300 conveyed by the bag-taking conveyor 54 through the storage box.

[0113] Preferably, the device body 10 further includes a sensor 13. The sensor 13 is disposed on the mounting frame 11, and the sensor 13 faces the integrally formed first bag film 100 and second bag film 200 released from the film dispensing roller 121. The sensor 13 is used to monitor the integrally formed first bag film 100 and second bag film 200 released from the film dispensing roller 121 in real time, thereby promptly detecting that the integrally formed first bag film 100 and second bag film 200 have been completely released from the film dispensing roller 121, and stopping the operation of the waste-collecting roll film packaging machine in a timely manner.

[0114] As an example, the sensing element 13 includes a laser sensor in real time.

[0115] It is understood that, in this embodiment, the integrally formed first bag film 100 and second bag film 200 released from the film feeding roller 121 are conveyed to the slitting member 212 by a plurality of guide rollers.

The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
