Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to a multi-row strip packaging machine. Background Art

[0002] Strip packing machines are mainly used for packaging granules, powders and liquid materials. The main processes include conveying packaging film, detecting color marks, guiding strip packs to form, sealing the longitudinal edges of strip packs, sealing the transverse edges of strip packs, filling materials, dividing strip packs, cutting easy-tear edges and rejecting defective products. Strip packing machines can pack single-row strip packs at a time, and can also produce multiple-row strip packs at a time. Multiple-row strip packing machines are suitable for the production of small-volume strip packs. Multiple-row strip packing machines often have inconsistent forces on each strip pack, which causes some strip packs to be overstressed and deformed, while some strip packs are understressed and cannot be completely stretched or transversely sealed. The strip packs have poor sealing, are not completely cut, and have various problems such as adhesion. The number of strip packs is limited, affecting production efficiency. The existing single-row or multi-row strip bagging machines generally have fixed longitudinal sealing mechanisms and cutting mechanisms, that is, they need to stop when the strip bag is longitudinally sealed and cut; generally, only one transverse sealing mechanism is set, and there is only one transverse sealing mechanism to pull the film and transversely seal. When the transverse sealing mechanism rises and returns to its position, the strip bag is basically in a static state due to lack of downward movement power, thus affecting the production speed of the strip bag. However, a single transverse sealing mechanism can only perform one transverse seal, and the sealing of the strip bag is difficult to ensure. At the same time, the film feeding mechanism often has the problem that the tension of the packaging film is difficult to control, and it is sometimes loose and sometimes tight, resulting in the difficulty in ensuring the accuracy of the strip bag length, affecting the quality of the final product; the film feeding mechanism also has the problem of wasting part of the packaging film at the tail end and being unable to feed the film, which cannot be fully utilized, resulting in wasted packaging film. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned disadvantages of the prior art and to provide a compact multi-row stick bag machine which can improve production speed and product quality and can be used for the production of liquid stick bags.

[0004] The present invention is achieved through the following technical solutions:

[0005] A multi-row strip bag machine comprises a first frame and a film feeding mechanism, a color mark detection mechanism, a longitudinal sealing mechanism, a first transverse sealing mechanism, a second transverse sealing mechanism and a punching mechanism arranged on the first frame, wherein the film feeding mechanism is used to feed the packaging film, the color mark detection mechanism is arranged on the conveying path of the packaging film and is used to detect the color mark on the packaging film, and the longitudinal sealing mechanism, the first transverse sealing mechanism, the second transverse sealing mechanism and the punching mechanism are arranged in sequence from top to bottom along the first frame. The strip bag is formed in the longitudinal sealing mechanism, and as the strip bag descends, the longitudinal edges of the strip bag are longitudinally sealed during the descending process; the first transverse sealing mechanism and the second transverse sealing mechanism are parallel to each other in the upper and lower parts, and are respectively used to perform the first transverse sealing and the second transverse sealing on the strip bag, and can heat-seal the longitudinal and transverse lines at the connection of the strip bag respectively, and the two transverse sealing mechanisms can alternately pull the film; the punching mechanism can descend with the strip bag and cut the strip bag during the descending process.

[0006] The present invention may also include a liquid metering mechanism, which is connected to the longitudinal sealing mechanism to deliver accurately measured liquid to the liquid injection pipe in the longitudinal sealing mechanism for filling in the strip package, and is used for the production of liquid strip packages.

[0007] Compared with the prior art, the present invention has the following beneficial effects: (1) Two sets of transverse seals are provided to perform two transverse seals on the strip bag, thereby improving the sealing performance of the transverse seals. The two sets of transverse seals can alternately pull the strip bag downwards. Compared with a single set of transverse seals, the time for the transverse seals to rise and return to their original positions is saved, and the film can be pulled without stopping for heat sealing, thereby improving the production speed. The two sets of transverse seals can ensure that there is always one set of transverse seals to clamp the strip bag, thereby avoiding inaccurate heat sealing position caused by shaking and twisting of the strip bag, and avoiding the contact of the non-heat sealing part with the heat sealing block due to the shaking of the strip bag, thereby improving the heat sealing quality. (2) Follow-up lifting modules are provided on the longitudinal sealing mechanism and the punching mechanism, so that the strip bag can be longitudinally sealed and cut while being pulled downwards. In combination with the two sets of transverse sealing mechanisms, the strip bag can be operated continuously during the entire production process. The first transverse sealing mechanism, the second transverse sealing mechanism and the punching mechanism all use a ball spline structure as the main power modules, so that the servo motor can be installed outside these mechanisms, and the servo motor and other driving components can be raised and lowered without these mechanisms, which greatly reduces the lifting load of the two transverse sealing parts and the punching part, and reduces the energy load and equipment cost; (4) The driving parts of the first transverse sealing mechanism, the second transverse sealing mechanism and the punching mechanism drive the relative functional modules to move synchronously to approach each other through the two connecting rod structures, and can control two relative functional modules, such as two The impact force between the heat-sealing block and the two punching cutters improves the heat-sealing and punching effects, and the unique structural designs such as the two-link structure, linkage frame, guide rod and two sets of drives make the heat-sealing blocks installed on the two horizontal sealing frames bear the same force for the horizontal sealing mechanism, thus avoiding various problems caused by uneven force on the heat-sealing blocks, such as some strip bags are not sufficiently stressed and the heat-sealing is not complete, there are still places without adhesion, some heat-sealing blocks are damaged by excessive impact force and clamping force, destroying the strip bags, or over-scalding, etc.; for the punching mechanism, various problems caused by uneven force on the cutters can be avoided, such as some strip bags are not sufficiently stressed and the punching is not complete, the strip bags are still adhered to each other, the waste edges are still adhered to the strip bags, and some cutters are severely worn due to excessive impact force, etc., which is suitable for multi-row strip bags The production of strip bags can be increased, and the number of strip bag production rows can be increased; (5) two longitudinal sealing clamps with lever structures are arranged on the longitudinal sealing mechanism, and the two longitudinal sealing clamps are driven to approach each other by a cam, so that the two hot-stamping blocks press the longitudinal edges of the strip bags to perform longitudinal sealing. The lever structure can make the two hot-stamping blocks move together or away from each other, and the opened opening is larger, which can be away from the strip bag film to avoid scalding the strip bag. The cam-type driving structure can make the overall structure compact, which is convenient for side-by-side layout on a multi-row strip bag machine. The triangular push block structure can adjust the pressing force during longitudinal sealing by adjusting the stroke size of the push block, which is easy to use; (6) The longitudinal sealing mechanism, the first transverse sealing mechanism, the second transverse sealing mechanism and the punching mechanism are arranged in sequence from top to bottom, and cooperate with each other through the lifting module, so that the overall structure is reasonable and compact, saving equipment space;(7) The film feeding mechanism is provided with two sets of drives, one for film feeding and the other for film pulling, so that the film feeding is more stable, and the difference between the two sets of drives and the unstable tension force that may occur during the film feeding process are reduced by the buffer component, so that the packaging film is sometimes tight and sometimes loose, so as to avoid the difficulty in controlling the length of the strip package and improve the accuracy of the strip package length. At the same time, the packaging film on the film feeding roller can be completely used up and the next film roll can be smoothly spliced ​​without wasting the packaging film; (8) The color mark detection and adjustment component can adjust the position of the color mark electric eye along the length direction of the packaging film, so as to adapt to the production of strip packages of different length specifications. The color mark detection and adjustment component is provided with a film pressing plate, so that the packaging film can be flattened and not curled during the color mark detection, so as to further improve the accuracy of the color mark detection, improve the accuracy of the strip package length control, and improve the product quality. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A multi-row charter, such as Figure 1 , Figure 3 , comprising a first frame 2 and a film feeding mechanism 3, a color mark detection mechanism 4, a longitudinal sealing mechanism 4, a first transverse sealing mechanism 6, a second transverse sealing mechanism 7 and a punching mechanism 8 arranged on the first frame 2, wherein the film feeding mechanism 3 is used to feed a packaging film 9, and the color mark detection mechanism 4 is arranged on the conveying path of the packaging film 9 and is used to detect a color mark 91 on the packaging film 9, such as Figures 4 to 6 The longitudinal sealing mechanism 4, the first transverse sealing mechanism 6, the second transverse sealing mechanism 7 and the punching mechanism 8 are arranged in sequence from top to bottom along the first frame 2. The multi-column stick bag machine of this embodiment is used for the production of liquid stick bags, so it also includes a liquid metering mechanism 1 arranged outside the first frame 2.

[0022] 1.Liquid metering mechanism 1

[0023] like Figure 2 The liquid metering mechanism 1 is arranged outside the first frame 2, and includes a second frame 11, a liquid storage tank 12 and a metering module 13. Several of the metering modules 13 are arranged side by side on the second frame 11. The liquid storage tank 12 is arranged on the second frame 11, and is connected with the inlets of several metering modules 13 through a main liquid pipe 14. The outlets of several metering modules 13 are connected one by one with the injection pipes in several strip bag guiding and forming modules 51 on the longitudinal sealing mechanism 4 through pipelines. The structure of the metering module 13 can refer to the structure of the liquid metering tank in the existing patent technology CN202210753042.7 of the applicant, and will not be described one by one here. Separating the liquid metering mechanism 1 from other mechanisms on the strip bag machine can prevent liquid leakage or cleaning from affecting other modules.

[0024] 2. Film feeding mechanism 3

[0025] like Figures 7 to 9 The film feeding mechanism 3 is used to feed the packaging film 9 to the subsequent process, and includes a film feeding roller 31, a traction roller 33 and a buffer assembly 34. The film feeding roller 31 is used to feed the packaging film 9, and the film feeding roller 31 is connected to a film feeding drive motor. The traction roller 33 and the buffer assembly 34 are arranged on the feeding path of the packaging film 9, and the traction roller 33 is connected to a film pulling drive motor for pulling the packaging film 9. The film feeding roller 31 and the traction roller 33 cooperate with each other to make the packaging film 9 on the film feeding roller 31 completely used up, that is, the film feeding roller 31 and the traction roller 33, one for feeding film and the other for pulling film, cooperate with each other to smoothly feed the film. When the packaging film 9 on the film feeding roller 31 is about to be used up and loses the tension, the traction roller 33 can pull the packaging film 9 that has lost the tension until the packaging film 9 is used up, and the tail end of the previous roll of packaging film 9 can be connected with the front end of the next roll of packaging film 9, so that the packaging film 9 can be completely used up and the packaging film 9 is not wasted.

[0026] The buffer assembly 34 includes a swing rod 341, a swing motor and a buffer roller 342. The swing rod 341 can be swingably installed on the frame. The swing motor is drivingly connected to one end of the swing rod 341 to drive the swing rod 341 to swing. At least one buffer roller 342 is installed on the other end of the swing rod 341, that is, the rotating shaft 5311 of the buffer roller 342 can be rotatably installed on the other end of the swing rod 341. The packaging film 9 is wrapped around the buffer roller 342. The swing motor adjusts the tension of the packaging film 9 by controlling the swing of the swing rod 341. The swing motor controls its rotation angle through an encoder, thereby controlling the swing amplitude of the swing rod 341 and adjusting the position of the buffer roller 342 to avoid the speed difference between the film feeding drive motor and the film pulling drive motor, which causes the tension of the packaging film 9 to be large or small, and the packaging film 9 to be loose or tight, resulting in different final lengths of the strips, affecting product quality.

[0027] The structure and form of the swing rod 341 can be designed according to actual conditions. As one implementation method, Fig. 9 The swing rod 341 includes a main rod 3411 and a support rod 3412 that are integrally arranged. The swing motor is connected to one end of the main rod 3411 to drive the main rod 3411 to swing. At least one support rod 3412 is arranged on the other end of the main rod 3411. One buffer roller 342 is installed at the end of each support rod 3412. The swing rod 341 is provided with two opposite left and right swing rods. The swing motor is connected to a transmission shaft. One end of the two swing rods 341 is connected to the two ends of the transmission shaft respectively. The two ends of the buffer roller 342 are installed on the other ends of the two swing rods 341 respectively.

[0028] The present invention further comprises at least one set of tensioning components 35, such as Fig. 9In this embodiment, two groups are provided, one above the other. Each group of the tensioning assembly 35 includes a tensioning roller 353 and two groups of tensioning adjustment structures. The two groups of tensioning adjustment structures are arranged opposite to each other on the left and right. Each group of the tensioning adjustment structures includes a hand wheel 351 and a screw nut pair 352. The hand wheel 351 is connected to the screw in the screw nut pair 352, and the two ends of the tensioning roller 353 are connected to the driving nuts 434 in the two groups of screw nut pairs 352. The hand wheel 351 drives the nut 434 to move along the screw, driving the tensioning roller 353 to move to control the tensioning force, which is generally used for equipment debugging before starting, while the buffer assembly 34 is used for real-time adjustment during equipment operation, which is performed autonomously by the swing motor according to the operating conditions.

[0029] like Figure 8 A film splicing platform 32 and a film inspection electric eye 37 are also provided on the conveying path of the packaging film 9. The film splicing platform 32 is provided with guide rollers 36 at both ends along the conveying direction of the packaging film 9. The packaging film 9 passes through the film splicing platform 32 via the guide rollers 36, and the front and rear rolls of packaging film 9 are automatically or manually connected end to end on the film splicing platform 32. In this embodiment, the film splicing platform 32 is provided at a position below the film feeding roller 31 and close to the film feeding roller 31, and the film inspection electric eye 37 is also provided at a position close to the film feeding roller 31, and is used to detect whether the packaging film 9 on the film feeding roller 31 is used up.

[0030] 3. Color mark detection mechanism 4

[0031] like Figures 10 to 13 The color mark detection mechanism 4 is arranged on the conveying path of the packaging film 9. The color mark detection mechanism 4 includes an adjustment seat 41, a color mark electric eye 42 and an adjustment component 43. The color mark electric eye 42 is fixed on the adjustment seat 41, and is used to detect the color mark 91 on the packaging film 9, and transmit the detection signal to the subsequent longitudinal sealing module 53, the transverse sealing module and the punching module to control the actions of these modules, thereby controlling the length of the strip package. The adjustment component 43 is connected to the adjustment seat 41 to drive the adjustment seat 41 to move along the length direction (conveying direction) of the packaging film 9, and adjust the relative position of the color mark electric eye 42 and the packaging film 9 to adapt to the production of strip packages of different length specifications.

[0032] The function of the adjusting member 43 is to adjust the position of the adjusting seat 41, which can be an existing mechanism and form, such as a structure driven by a cylinder 532. In the present embodiment, the adjusting member 43 includes an adjusting motor 431, a guide rod 432, a screw rod 433 and a driving nut 434. The guide rod 432 and the screw rod 433 are arranged on the frame in parallel with each other along the length direction of the packaging film 9, that is, the guide rod 432 and the screw rod 433 are parallel to the length direction of the packaging film 9, the adjusting motor 431 is connected to the screw rod 433 by driving, the driving nut 434 is screwed on the screw rod 433, the adjusting seat 41 is fixedly connected with the driving nut 434, and the adjusting motor 431 drives the adjusting seat 41 to move along the guide rod 432 (the length direction of the packaging film 9) through the screw rod 433 and the driving nut 434. The driving motor can also be replaced with a handle or a hand wheel 351 to manually drive the screw rod 433 to rotate. For the convenience of adjustment, a length scale 4321 is also provided on the guide rod 432.

[0033] In this embodiment, a film pressing plate 45 is arranged above the color mark electric eye 42, and the film pressing plate 45 is used to flatten the edge of the packaging film 9 to facilitate the color mark electric eye 42 to detect the color mark 91 at the edge of the film, thereby avoiding the influence of the winding of the packaging film 9 on the detection of the color mark 91, and the film pressing plate 45 is fixed on the adjustment seat 41.

[0034] The adjustment seat 41 includes an adjustment plate 411 extending along the width direction of the packaging film 9, and the adjustment plate 411 is provided with an elongated slot 412 extending along the width direction of the packaging film 9. The color standard electric eye 42 is mounted on the mounting plate 44, and the mounting plate 44 is movably mounted on the adjustment plate 411 through the elongated slot 412, so that the color standard electric eye 42 can be adjusted along the width direction of the packaging film 9 to adapt to different width specifications of the packaging film 9. Specifically, a fixing block 441 is provided on the mounting plate 44, and the fixing block 441 is fixed to the adjustment plate 411 by bolts after passing through the elongated slot 412, and the fixing block 441 can be moved along the elongated slot 412 to adjust its installation position.

[0035] In this embodiment, Fig.11The color mark detection mechanism 4 is provided with a pressing assembly 46 at the front end and the rear end along the conveying direction of the packaging film 9. The two groups of the pressing assemblies 46 are used to cooperate with each other to stretch and flatten the packaging film 9, so as to facilitate the color mark detection mechanism 4 to accurately detect the color mark 91 on the packaging film 9. Each group of the pressing assemblies 46 includes a pressing roller 461, a flattening roller 462 and an elastic member 463. The pressing roller 461 is arranged above the flattening roller 462 through the elastic member 463 and presses On the flattening roller 462, the packaging film 9 is respectively wound around the pressing roller 461 and the flattening roller 462, and the color mark detection mechanism 4 is located between the two flattening rollers 462 on the two groups of pressing components 46. The elastic member 463 is respectively connected to the two ends of the pressing roller 461 to control the pressing force between the pressing roller 461 and the flattening roller 462, so that the packaging film 9 between the two flattening rollers 462 is appropriately tight, not too tight to stretch the packaging film 9, and not too loose, so as to ensure the accuracy of the strip length. The structure of the elastic member 463 includes a spring, which is used for buffering.

[0036] 4. Vertical sealing mechanism 4

[0037] like Figures 14 to 21 The longitudinal sealing mechanism 4 includes a strip bag guiding and forming module 51, a first follow-up lifting module 52 and a longitudinal sealing module 53. Several of the strip bag guiding and forming modules 51 are horizontally fixed side by side on the first frame 2 (fixed, and the packaging film 9 is pulled by the first transverse sealing mechanism 6 and the second transverse sealing mechanism 7). The strip bag guiding and forming module 51 is used to guide the packaging film 9 into a strip bag shape and produce a longitudinal edge. Reference can be made to the existing technology, such as the relevant structure of the longitudinal sealing guide assembly in the existing patent CN202210753054.X of the applicant. The first follow-up lifting module 52 is installed on the first frame 2, and several of the longitudinal sealing modules 53 are horizontally installed side by side on the first mounting frame 54, and the number of the longitudinal sealing modules 53 is equal to the number of the strip bag guiding and forming modules 51, and the positions are one-to-one. The first mounting frame 54 is connected to the first follow-up lifting module 52. The first mounting frame 54 drives several groups of longitudinal sealing modules 53 to rise and fall synchronously with the strip bag under the drive of the first follow-up lifting module 52, and the longitudinal edges on the strip bag are longitudinally sealed during the descending process.

[0038] In this embodiment, the longitudinal sealing module 53 has a compact structure. Fig.14, multiple groups of longitudinal sealing modules 53 can be arranged side by side along the first mounting frame 54 to adapt to the production of multiple rows of strip packs. Specifically, multiple groups of fixing frames 531 on the longitudinal sealing modules 53 are fixed side by side on the first mounting frame 54. The first mounting frame 54 is connected to the follow-up lifting module. The first mounting frame 54 drives multiple groups of longitudinal sealing modules 53 to rise and fall synchronously under the drive of the follow-up lifting module. The first mounting frame 54 is provided with a first slider 541, and the first frame 2 is provided with a first slide rail 21 adapted to the first slider 541. The first mounting frame 54 rises and falls along the first frame 2 through the cooperation between the first slider 541 and the first slide rail 21.

[0039] The longitudinal sealing module 53 includes a fixing frame 531, a longitudinal sealing drive assembly, a first longitudinal sealing clamp 534, a first hot stamping block 535, a second longitudinal sealing clamp 536 and a second hot stamping block 537. The longitudinal sealing drive assembly is installed on the fixing frame 531. The first longitudinal sealing clamp 534 and the second longitudinal sealing clamp 536 are arranged opposite to each other. The middle position of the first longitudinal sealing clamp 534 and the second longitudinal sealing clamp 536 are installed on the fixing frame 531 through a rotating shaft 5311, so that the first longitudinal sealing clamp 534 and the second longitudinal sealing clamp 536 form a lever structure with the rotating shaft 5311 as a fulcrum. The first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 are structured such that both ends of the first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 are respectively divided by the rotating shaft 5311, and the first end of the first longitudinal sealing clamp block 534 is opposite to the first end of the second longitudinal sealing clamp block 536, and the second end of the first longitudinal sealing clamp block 534 is opposite to the second end of the second longitudinal sealing clamp block 536. When the first end of the first longitudinal sealing clamp block 534 and the first end of the second longitudinal sealing clamp block 536 are away from each other, the second end of the first longitudinal sealing clamp block 534 and the second end of the second longitudinal sealing clamp block 536 are close to each other (such as Fig. 20 , Fig.21 ); when the first end of the first longitudinal sealing clamp block 534 and the first end of the second longitudinal sealing clamp block 536 are close to each other, the second end of the first longitudinal sealing clamp block 534 and the second end of the second longitudinal sealing clamp block 536 are separated from each other (such as Figures 16 to 19 The first hot stamping block 535 is fixed on the second end of the first longitudinal sealing clamp 534, the second hot stamping block 537 is fixed on the second end of the second longitudinal sealing clamp 536, and the longitudinal sealing driving assembly is arranged at the first ends of the first longitudinal sealing clamp 534 and the second longitudinal sealing clamp 536, and is used to drive the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536 to move away from each other, so that the second end of the first longitudinal sealing clamp 534 and the second end of the second longitudinal sealing clamp 536 are close to each other, and the first hot stamping block 535 and the second hot stamping block 537 are close to each other, so as to longitudinally seal the strip pack (such as Fig. 20 , Fig.21 The first hot stamping block 535 and the second hot stamping block 537 are both provided with heating tubes, namely the first heating tube 5351 and the second heating tube 5371.

[0040] In order to make the first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 form a lever structure with one end open and the other end closed, in this embodiment, Fig.18 , Fig.21 , the edges of the middle positions of the first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 are both provided with protrusions extending outwards, which are respectively the first protrusion 5343 and the second protrusion, the rotating shaft 5311 is connected to the protrusions, and the protrusions on the first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 are installed on the same rotating shaft 5311. The first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 can be designed to have a bending structure with a certain angle.

[0041] The longitudinal sealing module 53 of the present invention can be raised and lowered under the drive of the first follower lifting module 52, and the longitudinal edges are longitudinally sealed as the strip package film descends, thereby avoiding pauses in the strip package production process and improving the production speed. The structure of the longitudinal sealing module 53 allows the two hot stamping blocks to open to each other and away from the strip package film when not performing heat sealing, and the opening is large, which has little impact on the strip package film, avoiding heat radiation damage to the strip package, and the overall structure is compact.

[0042] The function of the longitudinal sealing drive assembly is to make the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536 move away from each other, and the cylinder 532 can be used to push the two ends to open the two ends. In this embodiment, the longitudinal sealing drive assembly includes a cylinder 532 and a push block 533, the cylinder 532 is installed on the first frame 2, the push block 533 is fixed on the telescopic end of the cylinder 532, and is located in the middle position of the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536. The push block 533 enters between the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536 under the push of the cylinder 532, so that the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536 move away from each other, and the first hot stamping block 535 and the second hot stamping block 537 are close to each other to clamp the longitudinal sealing.

[0043] As one of the implementation methods, Fig.18 , Fig.19 The front end section of the push block 533 of this embodiment is triangular, and the two sides of the front end triangle are in contact with the first end of the first longitudinal sealing clamp block 534 and the first end of the second longitudinal sealing clamp block 536 respectively. The first end of the first longitudinal sealing clamp block 534 and the first end of the second longitudinal sealing clamp block 536 slide along the two sides of the front end triangle of the push block 533 as the cylinder 532 pushes and gradually moves away from each other. This structure can make the first longitudinal sealing clamp block 534 and the second longitudinal sealing clamp block 536 move smoothly, and the pressing force between the first hot stamping block 535 and the second hot stamping block 537 can be adjusted by adjusting the movement stroke of the push block 533.

[0044] In order to smoothly push the push block 533, rollers that can roll in contact with the two sides of the front triangle of the push block 533 are installed on the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536, respectively, and are the first roller 5341 and the second roller 5361. The two sides of the front triangle of the push block 533 roll with the first roller 5341 and the second roller 5361, respectively, so that the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536 gradually move away from each other. In this embodiment, the first longitudinal sealing clamp 534 and the second longitudinal sealing clamp 536 are both provided with connecting columns, respectively, the first connecting column 5342 and the second connecting column 5362, and the first roller 5341 and the second roller 5361 are respectively installed on the first connecting column 5342 and the second connecting column 5362.

[0045] In order to separate the first hot stamping block 535 and the second hot stamping block 537 from each other after heat sealing, a return structure is required, such as a tension spring or other elastic member 852 is provided at the position of the rotating shaft 5311. In this embodiment, a return spring 538 is connected between the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536. The return spring 538 brings the first end of the first longitudinal sealing clamp 534 and the first end of the second longitudinal sealing clamp 536 closer to each other through elastic restoring force, thereby moving the second end of the first longitudinal sealing clamp 534 and the second end of the second longitudinal sealing clamp 536 away from each other, and the first hot stamping block 535 and the second hot stamping block 537 are separated from each other, completing the longitudinal sealing.

[0046] The function of the first follow-up lifting module 52 is to drive the longitudinal sealing module 53 to move up and down, and it can be a commonly used lifting drive structure, such as a structure in which a motor drives a lead screw. In this embodiment, the first follow-up lifting module 52 is a driving structure in which a driving motor drives a synchronous belt, specifically, Fig.15 , including a third driving motor 521, a first driving wheel 522, a first driven wheel 523 and a first toothed belt 524, wherein the third driving motor 521, the first driving wheel 522 and the first driven wheel 523 are mounted on the first frame 2, the two first driven wheels 523 are arranged opposite to each other up and down, the first toothed belt 524 is wrapped around the first driving wheel 522 and the first driven wheel 523, the fixing frame 531 is fixed on the vertical gear belt between the two first driven wheels 523, the third driving motor 521 drives the fixing frame 531 on the first toothed belt 524 to move up and down, thereby driving the longitudinal sealing module 53 to rise and fall along the first frame 2.

[0047] 5. The first transverse sealing mechanism 6 and the second transverse sealing mechanism 7

[0048] like Figure 22 to Figure 27, the first transverse sealing mechanism 6 and the second transverse sealing mechanism 7 are parallel to each other in the upper and lower parts, and are respectively used for performing the first transverse sealing and the second transverse sealing on the strip pack, and alternately pulling the film (or strip pack); the first transverse sealing mechanism 6 and the second transverse sealing mechanism 7 have the same structure, taking the first transverse sealing mechanism 6 as an example, it includes a lifting drive module 61, a second mounting frame 62, a front heat sealing module, a rear heat sealing module and a transverse sealing drive module 63, the lifting drive module 61 is installed on the first frame 2, the front heat sealing module and the rear heat sealing module are relatively installed on the second mounting frame 62, the second mounting frame 62 is connected to the lifting drive module 61, and the second mounting frame 62 is lifted and lowered under the drive of the lifting drive module 61, driving the front heat sealing module and the rear heat sealing module to lift and lower together, thereby pulling a section of the strip pack downward; The front heat-sealing module includes a front transverse sealing frame 64 and a plurality of front heat-sealing blocks 65 arranged side by side on the front transverse sealing frame 64, and the rear heat-sealing module includes a rear transverse sealing frame 66 and a plurality of rear heat-sealing blocks 67 arranged side by side on the rear transverse sealing frame 66. The front transverse sealing frame 64 and the rear transverse sealing frame 66 are arranged opposite to each other, and the number of the front heat-sealing blocks 65 and the rear heat-sealing blocks 67 are equal, and their positions are relative to each other so that the front heat-sealing blocks 65 and the rear heat-sealing blocks 67 can cooperate with each other to clamp the strip package and perform transverse sealing on the strip package; the transverse sealing driving module 63 is respectively connected to at least one of the front transverse sealing frame 64 and the rear transverse sealing frame 66 to drive at least one of the front transverse sealing frame 64 and the rear transverse sealing frame 66 to move linearly, so that the front heat-sealing block 65 and the rear heat-sealing block 67 are close to each other to clamp and pull the strip package and perform transverse sealing on the strip package;

[0049] The structures of the first transverse sealing module and the second transverse sealing module are the same. Taking the first transverse sealing module as an example, it includes a lifting drive assembly, a second mounting frame 62, a front heat sealing module, a rear heat sealing module and a transverse sealing drive module 63, and the positions of the lifting drive assembly, the second mounting frame 62, the front heat sealing module, the rear heat sealing module and the transverse sealing drive module 63 on the first transverse sealing module and the second transverse sealing module are respectively opposite to each other, that is, the lifting drive assembly, the second mounting frame 62, the front heat sealing module, the rear heat sealing module and the transverse sealing drive module 63 on the first transverse sealing module are respectively opposite to the lifting drive assembly, the second mounting frame 62, the front heat sealing module, the rear heat sealing module and the transverse sealing drive module 63 on the second transverse sealing module.

[0050] The lifting drive assembly is installed on the first frame 2, and the front heat sealing module and the rear heat sealing module are relatively installed on the second mounting frame 62. The second mounting frame 62 is connected to the lifting drive assembly. The second mounting frame 62 is lifted and lowered under the drive of the lifting drive assembly, driving the front heat sealing module and the rear heat sealing module to lift and lower together, thereby pulling a section of the film strip downward; the front heat sealing module includes a front transverse sealing frame 64 and a plurality of front heat sealing blocks 65 arranged side by side on the front transverse sealing frame 64, and the rear heat sealing module includes a rear transverse sealing frame 66 and a plurality of rear heat sealing blocks 67 arranged side by side on the rear transverse sealing frame 66.

[0051] The transverse seal drive module 63 includes a first drive motor 631, a first ball spline structure, and a first connecting rod structure. The first drive motor 631 is installed on the first frame 2. The first ball spline structure includes a first spline shaft 632 and a first outer cylinder kit 633 sleeved on the first spline shaft 632 and capable of linear motion and rotational motion. The first spline shaft 632 is vertically arranged on the first frame 2. The first outer cylinder kit 633 is installed on the second mounting frame 62. The first drive motor 631 is connected to the first spline shaft 632 to drive the first spline shaft 632 to rotate. While driving the first outer cylinder kit 633 to rotate, the first outer cylinder kit 633 and the second mounting frame are connected. The frame 62 can be raised and lowered along the first spline shaft 632; the front transverse sealing frame 64 and the rear transverse sealing frame 66 are arranged opposite to each other, the number of front heat sealing blocks 65 and the rear heat sealing blocks 67 are equal, and the positions are relative to each other so that the front heat sealing blocks 65 and the rear heat sealing blocks 67 can cooperate with each other to clamp the strip package and perform transverse sealing on the strip package. The first outer cylinder kit 633 is connected to at least one of the front transverse sealing frame 64 and the rear transverse sealing frame 66 through the first connecting rod structure. The rotation of the first outer cylinder kit 633 drives at least one of the front transverse sealing frame 64 and the rear transverse sealing frame 66 to move in a straight line through the first connecting rod structure, so that the front transverse sealing frame 64 and the rear transverse sealing frame 66 are close to or away from each other, thereby making the front heat sealing block 65 and the rear heat sealing block 67 close to each other to perform transverse sealing on the strip package.

[0052] Two transverse sealing mechanisms (the first transverse sealing mechanism 6 and the second transverse sealing mechanism 7) are provided to perform transverse sealing at the same position of the strip package, which can improve the sealing quality. At the same time, the two transverse seals pull the film alternately, which can increase the speed. As one embodiment, the heat sealing faces of the front heat sealing block 65 and the rear heat sealing block 67 on the first transverse sealing module are both longitudinal grain structures, which are used to heat seal longitudinal grains on the strip package; the heat sealing faces of the front heat sealing block 65 and the rear heat sealing block 67 on the second transverse sealing module are both transverse grain structures, which are used to heat seal transverse grains at the position of the strip package close to the longitudinal grains heat-sealed by the first transverse sealing module. The transverse grains and the longitudinal grains are as close as possible, and the combination of the longitudinal grains and the transverse grains can enhance the sealing performance. The transverse grains are located below the longitudinal grains. After the strip package is cut, the transverse grains are located at the ends of the strip package, and the longitudinal grains are close to the middle of the strip package. The first transverse sealing module and the second transverse sealing module alternately pull the strip package downward, which saves the time for the transverse sealing module to rise and return to its position, and can increase the production speed. To this end, it is necessary for each component on the first transverse sealing module and the second transverse sealing module to operate independently.

[0053] The first ball spline structure allows the first drive motor 631 to be fixedly installed on the first frame 2 instead of being installed on the second mounting frame 62. The power can be transmitted through the first spline shaft 632 to drive the front heat sealing module and the rear heat sealing module to move linearly for heat transverse sealing. At the same time, the second mounting frame 62 can drive the front heat sealing module and the rear heat sealing module to move up and down. The external arrangement of the first drive motor 631 can greatly reduce the load weight of the second mounting frame 62, and can easily achieve lifting. In this embodiment, the transverse sealing drive module 63 has two groups arranged in parallel, and the two groups of transverse sealing drive modules 63 jointly drive the front heat sealing module and the rear heat sealing module to move closer or farther from each other, so as to adapt to the equipment with a large number of strip packs and make the force uniform. The strip packs in this embodiment are arranged in 12 rows in parallel. The above-mentioned first ball spline structure is used as the driving component of the transverse sealing drive module 63, and the two first drive motors 631 can be arranged outside the second mounting frame 62, further reducing the lifting load. In this embodiment, the second mounting frame 62, the front transverse sealing frame 64 and the rear transverse sealing frame 66 are all provided with hollow structures to further reduce the weight of the overall lifting. The hollow holes can also be used to drop the cutting waste edges. A waste belt is provided below, and the dropped waste edges fall on the waste belt and are discharged. Practice has proved that the above structure can reduce the lifting load by more than 2 / 3 compared with the traditional drive structure.

[0054] For the transverse sealing drive module 63, the first outer cylinder kit 633 is connected to at least one of the front transverse sealing frame 64 and the rear transverse sealing frame 66 through the first connecting rod structure, so that at least one of the two transverse sealing frames can move in a straight line. In this way, the two transverse sealing frames can be moved closer to or farther away from each other. It can be connected only to the front transverse sealing frame 64 to drive the front transverse sealing frame 64 to move in a straight line, or it can be connected only to the rear transverse sealing frame 66 to drive the rear transverse sealing frame 66 to move in a straight line, and it can also be connected to both the front transverse sealing frame 64 and the rear transverse sealing frame 66 at the same time to drive both to move simultaneously.

[0055] In this embodiment, in order to improve the driving effect, the transverse sealing driving module 63 drives the front transverse sealing frame 64 and the rear transverse sealing frame 66 to be synchronously linked. The specific structure is as follows: Fig.26 , Fig. 27, a first guide hole is provided on the second mounting frame 62, a first guide rod 637 is passed through the first guide hole (through a linear bearing), the first guide rod 637 can slide along the first guide hole, both ends of the first guide rod 637 pass through the first guide hole, namely the first end and the second end, the front transverse sealing frame 64 is fixed on the first end of the first guide rod 637, the rear transverse sealing frame 66 can be slidably mounted on the first guide rod 637 and is located between the second mounting frame 62 and the front transverse sealing frame 64, and a first linkage frame 636 is fixed on the second end of the first guide rod 637; the first connecting rod structure includes a front sealing connecting rod structure 634 and a rear sealing connecting rod structure 635, the first outer cylinder kit 633 is connected to the rear transverse sealing frame 66 through the rear sealing connecting rod structure 635, the first outer cylinder kit 633 is connected to the first linkage frame 636 through the front sealing connecting rod structure 634, and the first linkage frame 636 pushes the front transverse sealing frame 64 to move through the first guide rod 637. Such a structure allows the front and rear heat sealing modules to be synchronously driven by the same driving module, and the front and rear heat sealing blocks can be coordinated to improve the driving efficiency. At the same time, the two heat sealing modules can be located on the same side of the driving module, avoiding the strip package avoidance problem and the bulky structure caused by the driving module being located above, below or at both ends of the two heat sealing modules. In this embodiment, the first guide rod 637 has two parallel rods, which pass through the two ends of the second mounting frame 62 respectively, and the two sets of heat sealing driving modules are located in the middle of the second mounting frame 62, which can improve the stability of operation and have a compact structure.

[0056] As one of the embodiments, the front sealing link structure 634 includes a first front sealing link 6341 and a second front sealing link 6342, one end of the first front sealing link 6341 is fixedly connected to the first outer tube kit 633, and the other end is hinged to one end of the second front sealing link 6342, and the other end of the second front sealing link 6342 is hinged to the first linkage frame 636; the rear sealing link structure 635 includes a first rear sealing link 6351 and a second rear sealing link 6352, one end of the first rear sealing link 6351 is fixedly connected to the first outer tube kit 633, and the other end is hinged to one end of the second rear sealing link 6352, and the other end of the second rear sealing link 6352 is hinged to the rear cross sealing frame 66; the first front sealing link 6341 and the first rear sealing link 6351 are located in a straight line, that is, the first front sealing link 6341 and the first rear sealing link 6351 are respectively arranged on opposite sides of the first outer tube kit 633. Such a driving structure can make the rear transverse sealing frame 66 and the first linkage frame 636 approach each other or move away from each other, and the first linkage frame 636 and the front transverse sealing frame 64 are rigidly connected by the first guide rod 637, and the movement directions of the two are consistent. However, since the first linkage frame 636 and the front transverse sealing frame 64 are respectively located on both sides of the rear transverse sealing frame 66, when the rear transverse sealing frame 66 and the first linkage frame 636 approach each other, the rear transverse sealing frame 66 and the front transverse sealing frame 64 move away from each other, and vice versa.

[0057] Since the linear movement distance of the rear transverse sealing frame 66 and the front transverse sealing frame 64 is not too large, the rotation amplitude of the first spline shaft 632 is not very large and is in a swinging state. Therefore, in this embodiment, the first drive motor 631 is connected to the first spline shaft 632 through the third connecting rod structure 638. Compared with the method of directly connecting the first drive motor 631 to the first spline shaft 632, a more reasonable spatial layout can be performed, and the two first drive motors 631 can be vertically arranged beside the first frame 2, and the drive motor on the lifting drive module 61 is arranged horizontally. Specifically, the third connecting rod structure 638 includes a first transverse sealing drive link 6381 and a second transverse sealing drive link 6382. One end of the first transverse sealing drive link 6381 is connected to the first drive motor 631, and the other end is hinged to one end of the second transverse sealing drive link 6382. The other end of the second transverse sealing drive link 6382 is fixedly connected to the first spline shaft 632.

[0058] The lifting drive module 61 is used to drive the second mounting frame 62 to lift, and can be a structure in which a servo motor drives a lead screw. In order to further rationally arrange the space, the lifting drive module 61 in this embodiment is in the form of a servo motor driving a synchronous belt. Specifically, the lifting drive module 61 includes a fourth driving motor 611, a first transmission shaft 612, a second driving wheel 613, a second driven wheel 615 and a second toothed belt 614. The fourth driving motor 611 is installed on the first frame 2, and the first transmission shaft 612 is horizontally installed on the first frame 2. The fourth driving motor 611 and the first transmission shaft 612 are connected to each other. 12 transmission connection, the second driving wheel 613 is installed on the first transmission shaft 612 and rotates with the first transmission shaft 612, the second toothed belt 614 is vertically wrapped around the second driving wheel 613 and the second driven wheel 615, the second mounting frame 62 is fixed on the second toothed belt 614, the fourth drive motor 611 drives the second driving wheel 613 to rotate through the first transmission shaft 612, the second driving wheel 613 drives the second toothed belt 614 to move, thereby driving the second mounting frame 62 and the front heat sealing module and the rear heat sealing module thereon to rise and fall, so as to facilitate the horizontal sealing and the strip bag can be pulled downward. The second mounting frame 62 is also provided with a second slider 68, and the first frame 2 is correspondingly provided with a second slide rail 22, and the second mounting frame 62 can be raised and lowered along the first frame 2 through the cooperation of the second slider 68 and the second slide rail 22.

[0059] To further simplify the mechanism, in this embodiment, the second driven wheel 615 on the first transverse sealing module is rotatably mounted on the first transmission shaft 612 on the second transverse sealing module through a bearing, and there is no need to separately set a mounting shaft for the second driven wheel 615. The second driven wheel 615 on the second transverse sealing module can also be mounted on the first transmission shaft 612 on the first transverse sealing module through a bearing, and of course can also be directly mounted on the first frame 2. In this embodiment, the same lifting drive module 61 includes two sets of second driving wheels 613, second driven wheels 615 and second toothed belts 614 arranged in parallel, and the second mounting frame 62 is fixed on the two sets of second toothed belts 614.

[0060] Adopt the above-mentioned double horizontal sealing mechanism, such as Fig.28 , the double horizontal sealing method includes the following steps:

[0061] S1. The second mounting frame 62 of the first transverse sealing module moves downward under the drive of the lifting drive module 61. In the process of driving the front heat sealing module and the rear heat sealing module to move downward, the front heat sealing block 65 and the rear heat sealing block 67 on the first transverse sealing module are driven by the transverse sealing drive module 63 to approach each other and clamp the first strip bag, and then pull the strip bag downward for a length L1, and perform the first transverse seal on the first strip bag at the same time, that is, the first transverse seal is performed synchronously in the process of pulling the strip bag downward, and the heat sealing time must match the distance and speed of the pulling strip bag; at the same time, the second mounting frame 62 of the second transverse sealing module moves upward to a distance L2 under the drive of the lifting drive module 61 and stops moving upward.

[0062] S2. The second mounting frame 62 of the second transverse sealing module moves downward under the drive of the lifting drive module 61. In the process of driving the front heat sealing module and the rear heat sealing module to move downward, the front heat sealing block 65 and the rear heat sealing block 67 on the second transverse sealing module approach each other under the drive of the transverse sealing drive module 63 to clamp the strip package for the Nth time. Then, the first transverse sealing module releases the first strip package (that is, the front heat sealing block 65 and the rear heat sealing block 67 are driven away from each other by the transverse sealing drive module 63). The first transverse sealing module starts to rise back to its original position. During this process, the second transverse sealing module pulls the strip package downward. A length of L2, and at the same time, the second transverse seal is performed at the position of the first transverse seal of the Nth bag, that is, the second transverse seal is performed synchronously in the process of pulling the bag downward, and the heat sealing time must match the distance and speed of the pulling bag; when the first transverse sealing module clamps the next bag (that is, the next bag to be sealed next to the first bag), the second transverse sealing module releases the Nth bag, and then rises back to its position to complete a transverse seal of the Nth bag (vertical grain + horizontal grain, two transverse seals). The transverse seal position is the connection between the upper and lower bags, and the upper and lower bags can be cut apart by punching at the transverse seal position. At this time, the first bag has only completed the first transverse seal, and the second transverse sealing module will subsequently perform the second transverse seal on the first bag.

[0063] In the above steps, the first transverse sealing module and the second transverse sealing module have the same action, and both need to go through the four steps of downward synchronization and transverse seal clamping (clamping the strip package), pulling the film downward (or pulling the strip package downward), transverse seal opening (releasing the strip package), and quickly returning upward to complete each cycle of action. The two transverse seals cooperate with each other. When one transverse seal moves downward, the other transverse seal returns upward, but after one transverse seal clamps the strip package, the other transverse seal releases the strip package. In this way, it can be ensured that there is always a transverse seal module clamping and fixing the strip package, the strip package will not shake, and the transverse seal position is accurate.

[0064] The sum of the strip length L1 pulled by the first transverse sealing module and the strip length L2 pulled by the second transverse sealing module is equal to the length L of each strip. L1 and L2 can be determined according to the time of the two heat seals, and can be set to be the same or different. The speed at which the first transverse sealing module moves downward is equal to the speed at which the second transverse sealing module moves downward. In this way, when the two transverse sealing modules are connected, the two modules move downward, which can ensure that the two downward processes are synchronized and will not cause pulling on the strip film due to inconsistent speeds. The speed at which the two transverse sealing modules return upward can be faster than the speed at which they move downward, so that they can return quickly. In this embodiment, the times of downward synchronization, horizontal seal clamping, downward film pulling, horizontal seal opening, and rapid upward return of the four steps of the first horizontal sealing module are t1, t2, t3, and t4 respectively. The three steps of downward synchronization, horizontal seal clamping, downward film pulling, and horizontal seal opening are all performed in the process of downward synchronization. The time of downward synchronization is T3=t1+t2+t3, and the time of upward return is t4. The duration of one cycle of the first horizontal sealing module is T1=T3+t4=t1+t2+t3+t4; similarly, the time of downward synchronization, horizontal seal clamping, downward film pulling, horizontal seal opening, and rapid upward return of the four steps of the first horizontal sealing module are t5, t6, t7, and t8 respectively. The time of downward synchronization is T4=t5+t6+t7, and the time of upward return is t8. The duration of one cycle of the first horizontal sealing module is T2=T4+t8=t5+t6+t7+t8. As one implementation, t1 = t5, t2 = t6, t3 = t7, t4 = t8, T3 = T4, T1 = T2. Of course, the duration of each step of the two transverse sealing modules can also be set as required.

[0065] In this embodiment, 1<N≤10, the Nth package is the second package, the third package, the fourth package, the fifth package, the sixth package, the seventh package, the eighth package, the ninth package or the tenth package below the first package, that is, the strip packages clamped by the second transverse sealing module are other strip packages below the first transverse sealing module, and the first transverse sealing module and the second transverse sealing module do not heat-seal the transverse sealing positions of the same strip package in one transverse sealing cycle, and there are several strip packages in between. The specific number of strip packages in the interval depends on the length of the strip package and the size of the transverse sealing module.

[0066] 6. Punching mechanism 8

[0067] like Figure 29 to Figure 32The punching mechanism 8 includes a second follow-up lifting module 86, a third mounting frame 81, a front cutter module 82, a rear cutter module 83 and a cutter driving module 84. The second follow-up lifting assembly is mounted on the first frame 2. The front cutter module 82 and the rear cutter module 83 are relatively mounted on the third mounting frame 81. The third mounting frame 81 is connected to the second follow-up lifting module 86. The third mounting frame 81 is driven by the second follow-up lifting module 86 to lift and lower, driving the front cutter module 82 and the rear cutter module 83 to lift and lower together, so as to keep synchronization with the longitudinal sealing module 53 and the transverse sealing module on the strip bag machine, and to follow the strip bag belt to cut the strip bag during the descent. The follow-up cutting of the strip bag can avoid pulling the strip bag, or the strip bag belt is deformed and twisted due to accumulation, resulting in inaccurate and uneven cutting positions. This embodiment also includes a bag supporting module 85, which is mainly used to fix the strip bag before it is cut to avoid shaking of the strip bag during cutting.

[0068] The front cutter module 82 includes a front cutter frame 821 and a plurality of front cutters 822 arranged side by side on the front cutter frame 821, and the rear cutter module 83 includes a rear cutter frame 831 and a plurality of rear cutters 832 arranged side by side on the rear cutter frame 831. The front cutter frame 821 and the rear cutter frame 831 are arranged opposite to each other, and the number of the front cutters 822 and the rear cutters 832 are equal, and their positions are opposite to each other so that the front cutters 822 and the rear cutters 832 can cooperate with each other to punch the strips; the cutter driving module 84 is connected to at least one of the front cutter frame 821 and the rear cutter frame 831 to drive at least one of the front cutter frame 821 and the rear cutter frame 831 to move in a straight line, so that the front cutter 822 and the rear cutter 832 approach each other during the descending process to perform follow-up punching on the strips.

[0069] In this embodiment, the cutter drive module 84 includes a second drive motor 841, a second ball spline structure and a connecting rod structure. The second drive motor 841 is installed on the first frame 2, the second ball spline structure includes a second spline shaft 842 and a second outer cylinder set 843 sleeved on the second spline shaft 842 and capable of linear motion and rotational motion. The second ball spline structure is a conventional component and can be obtained commercially. Its structure and principle are not described in detail here. In this embodiment, the second spline shaft 842 is vertically arranged on the first frame 2, and the third mounting frame 81 is installed on the second outer cylinder set 843. The second drive motor 841 is connected to the second spline shaft 842 to drive the second spline shaft 842 to rotate, thereby driving the second outer cylinder set 843 to rotate, and the second outer cylinder set 843 and the third mounting frame 81 can be lifted and lowered along the second spline shaft 842. The rotation of the second outer cylinder assembly 843 drives at least one of the front cutting frame 821 and the rear cutting frame 831 to move linearly through the second connecting rod structure, so that the front cutting frame 821 and the rear cutting frame 831 are moved closer to or away from each other, thereby making the front cutting knife 822 and the rear cutting knife 832 approach each other to punch the strip pack.

[0070] The second ball spline structure allows the second drive motor 841 to be fixedly installed on the first frame 2 instead of being installed on the third mounting frame 81. The power can be transmitted through the second spline shaft 842 to drive the front cutter module 82 and the rear cutter module 83 to cut. At the same time, the third mounting frame 81 can drive the front cutter module 82 and the rear cutter module 83 to follow the lifting. The external arrangement of the second drive motor 841 can greatly reduce the load weight of the third mounting frame 81, and can easily achieve follow-up. In this embodiment, the cutter drive module 84 is provided with two parallel groups, and the two groups of cutter drive modules 84 jointly drive the synchronous linkage of the front cutter module 82 and the rear cutter module 83 to adapt to the equipment with a large number of strip packs and make the force uniform. The strip packs in this embodiment are provided with 12 parallel rows. The above-mentioned second ball spline structure is used as the driving component of the cutter drive module 84, and the two second drive motors 841 can be arranged outside the third mounting frame 81, which further reduces the lifting load. The third mounting frame 81, the front cutting frame 821 and the rear cutting frame 831 in this embodiment are all provided with hollow structures to further reduce the weight of the overall lifting. The hollow holes can also be used to cut the falling waste edges. A waste belt is provided below, and the fallen waste edges fall on the waste belt and are discharged.

[0071] For the cutter drive module 84, the second outer cylinder kit 843 is connected to at least one of the front cutter frame 821 and the second cutter frame through the second connecting rod structure, so that at least one of the two cutter frames moves linearly, so that the two cutter frames can be moved closer or farther away from each other. It can be connected only to the front cutter frame 821 to drive the front cutter frame 821 to move linearly, or it can be connected only to the rear cutter frame 831 to drive the rear cutter frame 831 to move linearly, and it can also be connected to the front cutter frame 821 and the second cutter frame at the same time to drive both to move simultaneously.

[0072] In this embodiment, in order to improve the driving effect, Fig.32 The cutter drive module 84 drives the front cutter frame 821 and the rear cutter frame 831 to be synchronously linked. The specific structure is that a second guide hole is provided on the third mounting frame 81, and a second guide rod 847 is penetrated in the second guide hole (through a linear bearing). The second guide rod 847 can slide along the second guide hole. Both ends of the second guide rod 847 pass through the second guide hole, namely, a first end and a second end. The front cutter frame 821 is fixed on the first end of the second guide rod 847, and the rear cutter frame 831 can be slidably mounted on the second guide rod 847 and is located between the third mounting frame 81 and the front cutter frame 821, and a second linkage frame 846 is fixed to the second end of the second guide rod 847; the second linkage structure includes a front cutter linkage structure 844 and a rear cutter linkage structure 845, the second outer cylinder kit 843 is connected to the rear cutter frame 831 through the rear cutter linkage structure 845, the second outer cylinder kit 843 is connected to the second linkage frame 846 through the front cutter linkage structure 844, and the second linkage frame 846 pushes the front cutter frame 821 to move through the second guide rod 847. Such a structure allows the two cutter modules to be synchronously driven by the same driving module, and the two cutters can be synchronously linked and coordinated, which can improve the driving efficiency, and at the same time, the two cutter modules can be located on the same side of the driving module, avoiding the problem of strip bag avoidance and bulky structure caused by the driving modules being located above, below or at both ends of the two cutter modules. In this embodiment, there are two parallel second guide rods 847 that pass through the two ends of the third mounting frame 81 respectively. The two sets of cutter drive modules 84 are located in the middle of the third mounting frame 81, which can improve the stability of operation and have a compact structure.

[0073] As one embodiment, the front cutter link structure 844 includes a first front cutter link 8441 and a second front cutter link 8442, one end of the first front cutter link 8441 is fixedly connected to the second outer cylinder set 843, and the other end is hinged to one end of the second front cutter link 8442, and the other end of the second front cutter link 8442 is hinged to the second linkage frame 846; the rear cutter link structure 845 includes a first rear cutter link 8451 and a second rear cutter link 8452, one end of the first rear cutter link 8451 is fixedly connected to the second outer cylinder kit 843, and the other end is hinged to one end of the second rear cutter link 8452, and the other end of the second rear cutter link 8452 is hinged to the rear cutter frame 831; the first front cutter link 8441 and the first rear cutter link 8451 are located in a straight line, that is, the first front cutter link 8441 and the first rear cutter link 8451 are respectively arranged on opposite sides of the second outer cylinder kit 843. Such a driving structure can make the rear cutting frame 831 and the second linkage frame 846 approach each other or move away from each other, and the second linkage frame 846 and the front cutting frame 821 are rigidly connected through the second guide rod 847, and the movement directions of the two are consistent. However, since the second linkage frame 846 and the front cutting frame 821 are respectively located on both sides of the rear cutting frame 831, when the rear cutting frame 831 and the second linkage frame 846 approach each other, the rear cutting frame 831 and the front cutting frame 821 move away from each other, and vice versa.

[0074] Since the distance of the linear movement of the rear cutting frame 831 and the front cutting frame 821 is not too large, the second spline shaft 842 will not rotate much and will be in a swinging state. Therefore, in this embodiment, the second drive motor 841 is connected to the second spline shaft 842 through the fourth connecting rod structure 848. Compared with the method of directly connecting the second drive motor 841 to the second spline shaft 842, the spatial layout can be more reasonably performed. The two second drive motors 841 can be vertically arranged beside the first frame 2, and the drive motor on the second follower lifting assembly can be arranged horizontally. Specifically, the fourth connecting rod structure 848 includes a first punching drive link 8481 and a second punching drive link 8482. One end of the first punching drive link 8481 is connected to the second drive motor 841, and the other end is hinged to one end of the second punching drive link 8482. The other end of the second punching drive link 8482 is fixedly connected to the second spline shaft 842.

[0075] The function of the second follower lifting assembly is to drive the third mounting frame 81 to rise and fall, and it can be a structure in which a servo motor drives a lead screw. In order to further rationally arrange the space, the second follower lifting assembly in this embodiment is in the form of a servo motor driving a synchronous belt. Specifically, the second follower lifting assembly includes a fifth drive motor 861, a second transmission shaft 862, a second transmission third driving wheel 863, a third driven wheel 865 and a third toothed belt 864. The fifth drive motor 861 is installed on the first frame 2, and the second transmission shaft 862 is horizontally installed on the first frame 2. The fifth drive motor 861 is connected to the second transmission shaft 862 in transmission connection. 863 is installed on the second transmission shaft 862 and rotates with the second transmission shaft 862, the third driven wheel 865 can be rotatably installed above the second transmission third driving wheel 863, the third toothed belt 864 surrounds the second transmission third driving wheel 863 and the third driven wheel 865, the third mounting frame 81 is fixed on the third toothed belt 864, the fifth driving motor 861 drives the second transmission third driving wheel 863 to rotate through the second transmission shaft 862, the second transmission third driving wheel 863 drives the third toothed belt 864 to move, thereby driving the third mounting frame 81 and the front cutting knife module 82 and the rear cutting knife module 83 thereon to rise and fall, so as to facilitate the follow-up cutting of strip packages. The third mounting frame 81 is also provided with a third slider 811, and the first frame 2 is correspondingly provided with a third slide rail, and the third mounting frame 81 can be raised and lowered along the first frame 2 through the cooperation of the third slider 811 and the third slide rail.

[0076] As one of the implementation methods, Figure 33 to Figure 36 The front cutter 822 is installed on the front cutter frame 821 through the front cutter seat 8221. The front cutter 822 has a convex edge 8222, and the upper and lower edges of the convex edge 8222 are both blade structures; the rear cutter 832 is installed on the rear cutter frame 831 through the rear cutter seat 8321. The rear cutter 832 includes two blades 8322 arranged upper and lower. The two blades 8322 cooperate with the blade structure on the front cutter 822 to cut off two adjacent strips from the connection. The upper blade 8322 and the blade cut the bottom of the previous strip, and the lower blade and the blade 8322 cut the top of the next strip.

[0077] In this embodiment, the two blades 8322 on the rear cutter 832 are arranged on the rear cutter seat 8321 in an inclined shape, and the two blades 8322 gradually approach each other in the direction of the front cutter 822 until a slit 8325 is formed between the two blades 8322, so that the waste edges after cutting can slide along the inclined surface after entering from the slit 8325, thereby avoiding the waste edges from being blocked at the cutting position. The front cutter seat 8221 is provided with a guide bar 8223, which can be integrated with the front cutter seat 8221, and the rear cutter seat 8321 is provided with a guide groove 8323 adapted to the guide bar 8223. The rear cutter 832 is positioned and matched with the front cutter 822 through the cooperation of the guide groove 8323 and the guide bar 8223, thereby avoiding position deviation when the two cutters cooperate.

[0078] In view of the need to open an easy-tear opening on some strip bags, the front cutting knife seat 8221 is also provided with an easy-tear opening blade 83228224, and the rear cutting knife seat 8321 is provided with an easy-tear opening knife groove 8324 compatible with the easy-tear opening blade 83228224. When the front cutting knife 822 and the rear cutting knife 832 cooperate with each other to cut an easy-tear opening, the easy-tear opening blade 83228224 and the easy-tear opening knife groove 8324 cooperate with each other to cut an easy-tear opening on the edge of the strip bag.

[0079] The bag support module 85 is mainly used to fix the strip bag to facilitate punching. Fig.32 , Fig.33 The bag supporting module 85 includes two bag supporting plates 851 arranged opposite to each other. The two bag supporting plates 851 are respectively connected to the front cutting knife frame 821 and the rear cutting knife frame 831 through elastic components 852, and the two bag supporting plates 851 are positioned opposite to each other.
