[0029] To make the technical solution, purpose and advantages of this utility model clearer, the following explanation is given in conjunction with the accompanying drawings and embodiments.

[0030] Example 1:

[0031] like Figures 1 to 3 As shown, the vertical packaging machine of this utility model has the following structural configuration:

[0032] The device includes a vertically mounted frame 1, a film feeding device 2 for discharging the packaging film at the front of the frame 1, and a forming device 3 for shaping the discharging packaging film at the rear. The forming device 3 is connected to a feeding device 100. The forming device 3 has film guiding devices 4 on both sides of its lower part to guide the packaging film downwards. The forming device 3 has a vertical sealing device 5 for vertical heat sealing of the packaging film at its lower rear part. The forming device 3 has a compression clamping device 6 for rolling and pressing the front and back sides of the packaging film at its lower part. The compression clamping device 6 has a sealing and cutting device 7 that moves with the downward movement of the packaging film at its lower part.

[0033] Specifically, the film unwinding device 2 includes a take-up roller 21 for winding and storing the packaging film. An unwinding device composed of multiple drive rollers 22 is provided between the take-up roller 21 and the upper position of the forming device 3. Under the pulling force of the film guiding device 4, the packaging film on the take-up roller 21 is unwound to the upper position of the forming device 3 for forming processing by the linkage guidance of the unwinding device.

[0034] The forming device 3 includes an arc-shaped shoulder 31 that cooperates with the film feeding device 2 to guide the film. A vertically cylindrical forming cylinder 32 is provided on the lower side of the arc-shaped shoulder 31. The feeding device 100 is connected to the inner side of the forming cylinder 32. The film guiding device 4 is provided on both sides of the forming cylinder 32. The vertical sealing device 5 is provided on the rear side of the middle section of the forming cylinder 32. The lower end of the forming cylinder 32 is provided with a corresponding extrusion clamping device 6.

[0035] The film guiding device 4 includes a transmission belt assembly 41 arranged longitudinally on both sides of the forming cylinder 32. The transmission belt assembly 41 includes a driving pulley 43 and a driven pulley 44 arranged on the upper and lower sides. A belt 42 is wound around the driving pulley 43 and the driven pulley 44. The driving pulley 43 is driven by a film guiding drive motor, and the driving pulley 43, in conjunction with the driven pulley 44, drives the belt 42 to rotate. During application, the belt 42 is arranged vertically towards the side of the forming cylinder 32, thereby achieving pressure contact with the outer side of the packaging film and friction driving the packaging film to move downwards as a whole. A flat support is provided at the bottom of the belt 42 towards the side of the forming cylinder 32 to ensure a smooth transmission path for the belt 42.

[0036] The vertical sealing device 5 uses a heating sealing device from the prior art, which is set vertically to meet the application of vertical heating sealing.

[0037] The extrusion clamping device 6 includes two extrusion rollers 61 arranged side by side in the front-back direction and an extrusion drive device 62 that drives the two extrusion rollers 61 to perform clamping actions towards or away from each other. The forming device 3 is provided with two bag expansion brackets 33 on the lower side for expanding the width of the packaging film. The two bag expansion brackets 33 are located between the two extrusion rollers 61 as the packaging film outlet position.

[0038] The sealing and cutting device 7 includes horizontal sealing blocks 71 arranged on both sides along the front-back direction and a sealing and clamping drive mechanism 72 that drives the horizontal sealing blocks 71 on both sides to perform a clamping action towards or away from each other. A cutting scissors 74 is arranged between the two horizontal sealing blocks 71. The position between the two horizontal sealing blocks 71 corresponds to the position below the position between the two extrusion rollers 61. The sealing and cutting device 7 is connected to a lifting drive device 73 to realize a lifting and following action that moves with the lower movement of the packaging film. Under the drive of the sealing and clamping drive mechanism 72, the horizontal sealing blocks 71 on both sides that move in both directions are linked to the cutting scissors 74 on both sides to perform a cutting action.

[0039] The application process and structural features of the above-mentioned packaging machine are as follows:

[0040] The sheet-shaped packaging film is fed from the take-up roller 21 by the film feeding device 2 and connected to the drive roller 22 to achieve the output of the packaging film towards the forming device 3. Guided by the arc-shaped shoulder 31 of the forming device 3, the two sides of the packaging film are rolled up towards the inward side (the rear side of the packaging machine shown in the figure). After being vertically heated and sealed by the vertical sealing device 5, the packaging film is formed into a cylindrical shape.

[0041] The tubular packaging film is guided by the forming cylinder 32 and driven by the two transmission belt groups 41 on both sides of the film guiding device 4, and is discharged downward as a whole. In the film guiding device 4, the two belts 42 on both sides are pressed with the forming cylinder 32 to guide and press the two sides of the discharged tubular packaging film in the width direction, so as to perform a shaping process to widen the two sides of the packaging film.

[0042] The tubular packaging film is guided downwards from the space between the two extrusion rollers 61. The bottom of the packaging film is then heated and sheared by the sealing and cutting device 7, which seals the bottom of the tubular packaging film and completes the pre-production preparation.

[0043] Production begins with the feeding device 100 introducing external material. For liquid materials, a corresponding pipe can be used, passing through the center of the arc-shaped shoulder 31 and connecting to the upper end of the forming cylinder 32 to allow the material to enter the inside of the forming cylinder 32. The input material is discharged from the lower part of the forming cylinder 32, passes through the bag expansion bracket 33, and falls between the two side extrusion rollers 61, filling the material through the packaging film sealed at the lower end.

[0044] Regarding the setting of the extrusion clamping device 6, based on the forming width of the packaging film, the target filling amount is preset to a distance from the bottom of the packaging film to the middle of the packaging film. Corresponding to the target filling amount, the height distance position of the packaging film is confirmed as the clamping position. The two extrusion rollers 61 are driven to press against each other to perform extrusion clamping action on the front and back sides of the packaging film. Under the extrusion clamping, the liquid material poured into the packaging film is divided into upper and lower sections.

[0045] During the production process, the packaging film continuously moves downwards under the weight of the filling material and the application of the film guiding device 4. The two side squeezing rollers 61 rotate under the clamping action to drive the packaging film downwards. The clamping and separating restricts the excess material beyond the target filling amount to the upper packaging film section of the squeezing and clamping device 6. During the squeezing and downward movement, the air in the upper part of the lower packaging film section (material-bearing film bag) is effectively squeezed out. This ensures that the lower material-bearing film bag meets the target filling amount while reducing the amount of air in the bag.

[0046] Based on the preset production target packaging height (distance from the bottom of the packaging film to the top position to be sealed), the target top sealing position in the material-lined film bag is preset. When the material-lined film bag is continuously exported and moved downwards, causing its top sealing position to move to the lower side of the extrusion clamping device 6, the horizontal sealing block 71 in the sealing and cutting device 7 located below the extrusion clamping device 6 is driven by the sealing and clamping drive mechanism 72 to perform lateral heating and sealing of the top sealing position, and the upper end of the lower material-lined film bag is cut by the cutting shears 74 to obtain the sealed packaging material.

[0047] When the horizontal sealing block 71 in the sealing and cutting device 7 heats and seals the upper sealing position of the previous material-filled film bag, the cutting scissors 74 make a horizontal cut along the middle of the horizontal sealing position. Then, the lower part of the material-filled film bag after cutting takes the lower part of the upper sealing position as the upper sealing end of its packaging material, and the upper sealing part of the cut upper sealing position forms the lower sealing end of the next section of packaging film, so that the lower sealing end of the next section of cylindrical packaging film forms a bag shape.

[0048] In this embodiment, the material filling process is continuous. The next segment of the bag-shaped packaging film has already completed material filling preparation after the previous packaging material was cut and produced, forming a bag with material. Then, based on the preset clamping position of the next bag with material, the compression clamping device 6 is repeatedly driven to compress and clamp the bag with material. Because heat sealing and cutting processes require time, the sealing and cutting device 7 moves as the bag with material descends during the lateral heat sealing and cutting process. During the compression clamping process of the next bag with material, the sealing and cutting device 7 is reset under the drive of the lifting drive device 73, and thus repeatedly performs lateral sealing and cutting at the upper sealing position of the next bag with material, completing the production of the next material package. This achieves uninterrupted production of packaging materials.

[0049] In the above application, the clamping position is set based on the forming width of the packaging film processed by the equipment, combined with the target filling amount of the material, and the resulting material filling height distance is used as the target filling amount.

[0050] Example 2:

[0051] As a preferred structural embodiment, the extrusion clamping device 6 is preferably configured as follows: it includes a mounting plate 60 arranged horizontally. A guide opening 603 is provided on the mounting plate 60, and extrusion rollers 61 are arranged side-by-side on both sides of the horizontal direction corresponding to the guide opening 603. An extrusion drive device 62 is connected between the two extrusion rollers 61 to drive the two extrusion rollers 61 to perform clamping actions towards or away from the guide opening 603. In application, the independent arrangement of the mounting plate 60 allows the extrusion clamping device 6 to be integrally adapted and installed on the frame 1, meeting installation requirements. Simultaneously, the guide opening 603 more clearly and effectively guides the insertion position of the packaging film, facilitating its smooth introduction before production preparation.

[0052] Specifically, the mounting plate 60 includes a base plate portion 601 and mounting arms 602 extending from both sides of the rear end of the base plate portion 601. A U-shaped guide opening 603 is formed between the base plate portion 601 and the mounting arms 602 on both sides.

[0053] The extrusion drive device 62 includes guide rods 621 extending along the front-back direction on both sides of the mounting arm 602. The mounting plate 60 is provided with positioning blocks 604 to position and connect the guide rods 621 on both sides. The guide rods 621 on both sides are positioned at the lower side of the mounting arm 602 on both sides. It also includes a reciprocating drive motor 622 with vertical positioning, the output end of which is rotatably connected to the center of a drive plate 623; one end of the drive plate is pivotally connected to a first drive arm 624, one end of which is rotatably connected to a first extrusion bracket 625, the first extrusion bracket 625 being movably connected to guide rods 621 on both sides, and the extrusion roller 61 including a first extrusion roller 611 connected to the first extrusion bracket 625; the other end of the drive plate is pivotally connected to a second drive arm 626, one end of which is rotatably connected to a linkage plate 627, the linkage plate 627 being positioned between one end of the two guide rods 621; the other end of the two guide rods 621 is positioned and connected to a second extrusion bracket 628, and the extrusion roller 61 including a second extrusion roller 612 connected to the second extrusion bracket 628.

[0054] The forward or reverse rotation of the reciprocating drive motor 622, in conjunction with the connecting drive plate 623, drives the first drive arm 624 and the second drive arm 626 to extend away from or retract towards the drive end of the reciprocating drive motor 622. Under the guidance and restriction of the guide rod 621, the extended first drive arm 624 drives the first extrusion bracket 625 to move closer to the guide opening 603, and the extended second drive arm 626 drives the linkage plate 627 to pull the guide rods 621 on both sides, thereby moving the second extrusion bracket 628 and the second extrusion roller 612 closer to the guide opening 603. This achieves a clamping action in which the first extrusion rollers 611 and the second extrusion roller 612 on both sides move towards each other.

[0055] Based on the above-described drive structure, the horizontal coordinated drive of the two extrusion rollers 61 can be effectively realized. Correspondingly, the sealing clamp drive mechanism 72 in the sealing and cutting device 7 can also be selected based on the above-described drive structure to perform the linkage drive of the horizontal sealing block 71 and the cutting shears 74.

[0056] To better meet the application requirements of clamping and extrusion applications and the application requirements of stable transmission of packaging film assisted by the extrusion clamping device 6, the first extrusion bracket 625 is connected to the first extrusion roller 611 by a first drive motor, and the first extrusion bracket 625 is provided with a first driven roller 6111. The first drive motor drives the first driven roller 6111 by a transmission belt 42. The first extrusion roller 611 and the first driven roller 6111 are arranged side by side in the vertical direction. The second extrusion bracket 628 is connected to the second extrusion roller 612 by a second drive motor, and the second extrusion bracket 628 is provided with a second driven roller 6121. The second drive motor drives the second driven roller 6121 by a transmission belt 42. The second extrusion roller 612 and the second driven roller 6121 are arranged side by side in the vertical direction.

[0057] The above description is only a preferred embodiment of the present utility model. For those skilled in the art, modifications can still be made to the embodiments without departing from the implementation principle of the present utility model, and the corresponding modifications should also be considered within the protection scope of the present utility model.
