[0044] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0045] 1. The packaging machine of the present invention, through the arranged linkage transmission component, turns on the driving motor to drive the second conveyor to transport the plastic bowls and the material belt. When the third chain moves, it can also drive the second linkage shaft and the third conveyor to move synchronously, so as to transmit the transversely sealed material belt and the bowl at the same linear speed. When the driving motor outputs, it can also synchronously drive the second chain to move at the same linear speed, and can drive the first changing wheel and the second changing wheel to rotate. When the second changing wheel outputs, on the one hand, it can drive the first clamping roller to rotate, and at the same time drive the second clamping roller to perform secondary power transmission to the material belt to prevent the material belt from stagnation. On the other hand, it can cooperate with the transmission of the first conveyor and the second conveyor to stretch the material belt to prevent the material belt from collapsing due to the heat sealing force when the material belt is transversely sealed, resulting in the horizontal edge of the heat-sealed material belt being unsealed. When the film is delivered to the carrier, the second gear is engaged and the second gear is engaged, so that the carrier can be delivered to the carrier by the second clamping roller and the incomplete gear to perform a micro-rotation and tensioning operation. When the incomplete gear is in the micro-rotation and tensioning state, the pressure stabilizing plate can be effectively driven to perform a small-scale flip and the pressure stabilizing hanging spring can be pulled to expand and contract. At the same time, the pressure stabilizing cylinder can be put into a side-turning state, so as to effectively tension the packaging film strip to ensure the continuity and stability during film feeding. In addition, when the driving motor moves, the first chain and the third chain can be driven to transmit at the same linear speed. After the first chain is in the starting state, it can synchronously promote the follow-up anti-adhesion component and the transverse sealing component to start the operation. Through the operation of the linkage transmission component, the continuity and linkage of the second conveyor, the third conveyor, the first clamping roller, the second clamping roller, the follow-up anti-adhesion component and the transverse sealing component can be guaranteed, which saves operation time and the problem of difficult handling of the material strips of each part during the operation process.

[0046] 2. The packaging machine of the present invention, through the arrangement of the follow-up anti-adhesion component, before the linkage transmission component is started to drive the follow-up anti-adhesion component to operate as a whole, firstly, the first pull rod is toggled to make the material strip pass through the gap between the elastic contact and the chassis in sequence to complete the filling operation of the material strip. In the process of the material strip passing through the gap and moving, on the one hand, the material strip can be clamped as a whole by the two sets of chassis to prevent the material strip from being wrinkled due to the material strip film opening not being closed when the material strip is about to enter the transverse sealing component for transverse sealing. On the other hand, On the one hand, when the two sets of chassis are in the clamping and conveying state, the elastic pulling of the first guide pin and the first hanging spring can make the two sets of chassis adaptively slightly open as the material belt moves to avoid the situation that the material belt is clamped too tightly and the material belt is difficult to move. On the other hand, because the anti-adhesion ring can be adaptively moved downward to guide the material belt film opening downward, in the process of guiding the material belt film opening downward, it can prevent the sealing position of the material belt film opening from being too high, which will cause the material belt above the bag opening after transverse sealing to be hot-melted.

[0047] 3. The packaging machine of the present invention utilizes elastic contacts to effectively block and adhere the transverse seal of the material strip as it passes between the two sets of elastic contacts and is blocked by the multiple sets of spherical protrusions. The elastic contacts and the anti-adhesion collars also guide the material strip downward. This downward guidance of the film opening of the material strip prevents the film opening from being too high, which could cause the material strip above the transversely sealed bag opening to melt.

[0048] 4. The packaging machine of the present invention uses a transverse sealing member to pull the second pull rod before the linkage transmission member starts to drive the transverse sealing member as a whole to operate, so that the material strip passes through the two sets of transverse sealing wheels. When the material strip passes through the two sets of transverse sealing wheels, the transverse sealing operation of the material strip is completed. In addition, the two sets of self-driving wheels can be synchronously driven by the linkage transmission member to maintain the same speed as the linkage transmission member to perform the transverse sealing operation. When the transverse sealing operation is completed on half of the material strip, it continues to move forward and the second guide pin has a tendency to rotate clockwise, which can drive the second hanging spring to stretch, so as to perform the adaptive transverse sealing operation on the other half that has not yet moved. This can effectively prevent the half of the material strip that has not been transversely sealed from stopping suddenly in the transverse sealing member.

[0049] 5. The packaging machine of the present invention, through the longitudinal sealing components arranged, when the material strip that has completed transverse sealing enters the longitudinal sealing component, then turns on the pushing cylinder to make the output end of the pushing cylinder output, so as to push the tail plate to move outward, and after the tail plate moves outward, it can pull the side push rod to rotate clockwise, and after the side push rod rotates clockwise, one end of the side push rod can pull the first longitudinal sealing plate to the left, and the other end of the side push rod can push the second longitudinal sealing plate to the right, so as to quickly perform the longitudinal sealing operation on the material strip that has completed transverse sealing, and by turning on the switch of the shearing cylinder, the cutter on the output end of the shearing cylinder can be driven to cut the material strip that has completed longitudinal sealing, so as to facilitate the subsequent continuous transverse and longitudinal sealing operations of the material strip.

[0075] In the present invention, it should be noted that the three-axis mechanical gripper 13 is a known component in the prior art, so it will not be described in detail in the present invention. In actual operation, multiple groups of plastic bowls to be packaged are first placed on the material conveyor 11, and then the material conveyor 11 is turned on. When the plastic bowls move to the bottom of the three-axis mechanical gripper 13, the three-axis mechanical gripper 13 is turned on. The plastic bowls can be grasped and transferred in six directions: up, down, left, right, front and back, which allows for more flexible grasping and transfer.

[0076] It should also be noted that the handwheel linear module 5 is a known component in the prior art. The handwheel linear module 5 is composed of a connecting shell, a screw rod in the connecting shell, a ball base sleeved in the connecting shell, and a handwheel connected to the screw rod. After turning the handwheel, the screw rod base can be raised or lowered. The ball base constitutes the moving end of the handwheel linear module 5, so the handwheel linear module 5 is not described in detail.

[0077] When the film conveying component 3 is used as a whole, the material strip roll is first placed on the material barrel 32, and the material strip is pulled through multiple sets of transmission rollers 33, the first clamping roller 34, the second clamping roller 35 and the guide roller 36 in sequence, and the material strip is brought to the first conveyor 21. The plastic bowl is grabbed by the three-axis mechanical gripper 13 and sent to the material strip, and the first conveyor 21 is turned on for transportation.

[0078] Next, the linkage transmission component 4 is given a more specific structure and construction as a whole for further explanation. The linkage transmission component 4 includes a drive motor 41, which is arranged in the packaging machine box 2. A first linkage shaft 42 is arranged at the output end of the drive motor 41, and the first linkage shaft 42 can penetrate into the second conveyor 22 to drive the second conveyor 22 to move. A first sprocket 43 is arranged on the first linkage shaft 42, and a first chain 44 is arranged on the first sprocket 43; a second chain 45 is arranged on the second conveyor 22, a second sprocket 47 is arranged in the second chain 45, and a third linkage shaft 46 is arranged in the second sprocket 47. The third linkage shaft 46 can pass through the packaging chassis 2, and a first changing wheel 48 is arranged at one end of the third linkage shaft 46; the second changing wheel 49 is arranged at the tail end of the first clamping roller 34, and the second changing wheel 49 is meshed with the first changing wheel 48; the incomplete gear 493 is arranged at the tail end of the second clamping roller 35, and a stabilizing plate 492 is arranged at the notch of the incomplete gear 493, and a stabilizing spring 491 is provided at one end of the stabilizing plate 492, and the stabilizing spring 491 is hung with the packaging chassis 2; the stabilizing cylinder 494 is arranged on the packaging chassis 2, and the output end of the stabilizing cylinder 494 is connected to the stabilizing plate 492;

[0079] Next, the overall use principle and specific effects of the linkage transmission component 4 are further explained. By turning on the drive motor 41, the second conveyor 22 is driven to transport the plastic bowls and the material belt. When the third chain 451 moves, the second linkage shaft 452 and the third conveyor 23 can be driven to move synchronously to transmit the transversely sealed material belt and bowls at the same linear speed. When the drive motor 41 is output, the second chain 45 can be driven synchronously to move at the same linear speed, and the first changing wheel 48 and the second changing wheel 49 can be driven to rotate. When the second changing wheel 49 is output, on the one hand, it can drive the first clamping roller 34 to rotate, and at the same time drive the second clamping roller 35 to perform secondary power transmission to the material belt to prevent the material belt from stagnation. On the other hand, it can cooperate with the transmission of the first conveyor 21 and the second conveyor 22 to stretch the material belt to prevent the material belt from collapsing due to the heat sealing force when the material belt is transversely sealed, resulting in the horizontal edge of the heat-sealed material belt not being sealed. In the case of sealing, the third aspect can drive the second clamping roller 35 and the incomplete gear 493 to slightly rotate and tighten when the material belt moves. When the incomplete gear 493 is in the slightly rotated and tightened state, it can effectively drive the pressure stabilizing plate 492 to perform a small-scale flip and pull the pressure stabilizing hanging spring 491 to expand and contract. At the same time, it can make the pressure stabilizing cylinder 494 in a side-turning state, which can effectively tension the packaging film material belt to ensure continuity and stability during film feeding. In addition, when the drive motor 41 moves, it can also bring The first chain 44 and the third chain 451 are transmitted at the same linear speed. After the first chain 44 is in the starting state, it can synchronously push the follow-up anti-adhesion component 6 and the transverse sealing component 7 to start the operation. Through the operation of the linkage transmission component 4, the continuity and linkage of the second conveyor 22, the third conveyor 23, the first clamping roller 34, the second clamping roller 35, the follow-up anti-adhesion component 6 and the transverse sealing component 7 can be guaranteed during operation, saving operation time and the problem of difficult handling of the material belts of various parts during the operation.

[0080] In some embodiments, more specifically, in the initial state, the output end of the pressure-stabilizing cylinder 494 is in an unextended state, the pressure-stabilizing spring 491 is in an unstretched state, and the pressure-stabilizing spring 491 is located below the pressure-stabilizing plate 492. When the horizontal and vertical sealing are completed, the pressure-stabilizing plate 492 can be pushed back to the initial position by opening the pressure-stabilizing cylinder 494, and the film-delivering component 3 as a whole can be quickly put into a waiting state.

[0081] Next, a more specific structure and construction of the follower anti-adhesion component 6 is given as a whole for further explanation. The follower anti-adhesion component 6 includes a follower frame 61, which is arranged at the moving end of the handwheel linear module 5. A first follower shaft 62 is provided in the follower frame 61, and the first follower shaft 62 can be driven and rotated by the first chain 44. A third changing wheel 63 is provided at one end of the first follower shaft 62; two sets of anti-adhesion shafts 64, one of which is provided with a fourth changing wheel 65, and the fourth changing wheel 65 is meshed with the third changing wheel 63; two sets of chassis 6 6, respectively arranged on the two sets of anti-adhesion shafts 64, forming a gap between the two sets of chassis 66; a first pull rod 67, which is arranged on the other set of anti-adhesion shafts 64; a first guide pin 68, which is arranged on the other set of anti-adhesion shafts 64, and a first hanging spring 69 is arranged on the first guide pin 68, and the first hanging spring 69 is connected to the follower frame 61; an anti-adhesion ring 691, which has an embedded notch, and an elastic contact 692 is arranged at the bottom of the anti-adhesion ring 691 body; a positioning pin 693, which can pass through the embedded notch and be positioned on the follower frame 61;

[0082] Next, the use principle and specific effect of the follower anti-adhesion component 6 as a whole are further explained. Before the linkage transmission component 4 starts to drive the follower anti-adhesion component 6 as a whole to operate, the first pull rod 67 is first toggled to allow the material strip to pass through the gap between the elastic contact 692 and the chassis 66 in turn to complete the filling operation of the material strip. In the process of the material strip passing through and moving through the gap, on the one hand, the material strip as a whole can be clamped by the two sets of chassis 66 to prevent the material strip membrane from not closing when the material strip is about to enter the transverse sealing component 7 for transverse sealing, thereby preventing wrinkles at the transverse sealing material opening. On the one hand, when the two sets of chassis 66 are in a clamping and conveying state, the elastic pulling of the first guide pin 68 and the first hanging spring 69 can make the two sets of chassis 66 adaptively slightly open as the material belt moves to avoid the situation where the material belt is clamped too tightly and difficult to move. On the other hand, the anti-adhesion ring 691 can be adaptively moved downward to guide the material belt membrane mouth downward. In the process of guiding the material belt membrane mouth downward, it can prevent the sealing position of the material belt membrane mouth from being too high, which will cause the material belt above the bag mouth after horizontal sealing to be hot-melted.

[0083] In some embodiments, more specifically, multiple groups of spherical protrusions are integrally formed in the two groups of elastic contacts 692, and an anti-adhesion gap is formed between the two groups of elastic contacts 692;

[0084] Next, the use principle and specific effects of the elastic contacts 692 are further explained. When the material strip passes through the two sets of elastic contacts 692, after being blocked by multiple sets of spherical protrusions, the horizontal seal of the material strip can be effectively blocked and fitted. After the joint action of the elastic contacts 692 and the anti-adhesion ring 691, the material strip can be guided downward. In the process of guiding the film opening of the material strip downward, the sealing position of the film opening of the material strip can be prevented from being too high, which will cause the material strip above the bag opening after horizontal sealing to be hot-melted.

[0085] Then, the structure and construction of the horizontal sealing member 7 as a whole are given a more specific explanation. The horizontal sealing member 7 includes a horizontal sealing frame 71, which is arranged at the moving end of the handwheel linear module 5. A second follower shaft 72 is rotatably arranged in the horizontal sealing frame 71, and the second follower shaft 72 can be driven and rotated by the first chain 44, and a fifth changing wheel 73 is arranged on the second following shaft 72; two sets of horizontal sealing columns 74 are rotatably arranged in the horizontal sealing frame 71, and a sixth changing wheel 75 is arranged on one set of horizontal sealing columns 74, and the sixth changing wheel 75 is meshed with the horizontal sealing columns 74, and both sets of horizontal sealing columns 74 have a self-driving wheel 76, and the two sets of self-driving wheels 76 are meshed with each other; two sets of horizontal sealing wheels 77 are respectively located at the bottom of the two sets of horizontal sealing columns 74, and a horizontal sealing gap is formed between the two sets of horizontal sealing wheels 77; a second pull rod 78 is arranged on the other set of horizontal sealing wheels 77;

[0086] Next, the overall use principle and specific effects of the transverse sealing member 7 are further explained. Before the linkage transmission member 4 starts to drive the transverse sealing member 7 to operate as a whole, the second pull rod 78 is pulled to allow the material belt to pass through the two sets of transverse sealing wheels 77. When the material belt passes through the two sets of transverse sealing wheels 77, the transverse sealing operation of the material belt can be completed. In addition, the two sets of self-driving wheels 76 can be driven synchronously by the linkage transmission member 4 to maintain the same speed as the linkage transmission member 4 for transverse sealing operation. When half of the material belt completes the transverse sealing operation, it continues to move forward and can make the second guide pin 79 tend to rotate clockwise. It can drive the second hanging spring 791 to stretch, so as to perform adaptive transverse sealing operation on the other half that has not been completed, which can effectively prevent the half of the material belt that has not been transversely sealed from stopping suddenly in the transverse sealing member 7.

[0087] In some embodiments, more specifically, the transverse sealing member 7 further includes a second guide pin 79, which is arranged on another set of transverse sealing wheels 77, and a second hanging spring 791 is arranged on the second guide pin 79, and the second hanging spring 791 is connected to the transverse sealing frame 71; wherein, when the second guide pin 79 tends to rotate clockwise, it can drive the second hanging spring 791 to stretch.

[0088] In some embodiments, more specifically, an annular friction plate is disposed above each of the two sets of self-driving wheels 76 , and the two sets of annular friction plates are in a state of mutual conflict in an initial state;

[0089] Through the arrangement of the annular friction plates, when the self-driving wheel 76 rotates, it can synchronously drive the two groups of annular friction plates to perform contact friction. When half of the material strip completes the transverse sealing operation, the two groups of annular friction plates can generate friction. On the one hand, it can further reduce the situation where the half of the material strip that has not completed the transverse sealing operation is suffocated in the transverse sealing component 7. On the other hand, by increasing the friction between the annular friction plates, the time the material strip stays in the two groups of transverse sealing wheels 77 can be further delayed. By delaying the time the material strip stays in the transverse sealing wheel 77, the transverse sealing effect of the material strip can be further improved.

[0090] Next, a more specific structure and construction of the longitudinal sealing member 8 is given as a whole for further explanation. The longitudinal sealing member 8 includes a longitudinal sealing frame 81, which is arranged at the rear section of the packaging box 2 and has a long axis 82 in the longitudinal sealing frame 81; a pushing cylinder 83, which is arranged on the longitudinal sealing frame 81, and a tail plate 84 is arranged at the output end of the pushing cylinder 83; a side push rod 85, which is rotatably arranged on the tail plate 84, and a first oblique rod 86 is rotatably provided on one tail end of the side push rod 85, and a first longitudinal sealing plate 88 capable of sliding on the long axis 82 is arranged on the first oblique rod 86; a second oblique rod 87, which is rotatably arranged at the other tail end of the side push rod 85, and a second longitudinal sealing plate 89 capable of sliding on the long axis 82 is rotatably provided on one end of the second oblique rod 87, and an embedded rod 892 is further provided in the second longitudinal sealing plate 89, and a spring 893 is removably provided on the embedded rod 892;

[0091] It should also be noted that the arranged spring 893 and the embedded rod 892 can effectively buffer the second longitudinal sealing plate 89 when it contacts the first longitudinal sealing plate 88, and can correct the deviation of the first longitudinal sealing plate 88 and the second longitudinal sealing plate 89 when they are docked, so that the serrations on the two tool holders can be staggered and plugged in.

[0092] Next, the overall usage principle and specific effects of the longitudinal sealing component 8 are further explained. After the transversely sealed material strip enters the longitudinal sealing component 8, the pushing cylinder 83 is turned on to make the output end of the pushing cylinder 83 output, so as to push the tail plate 84 to move outward. After the tail plate 84 moves outward, it can pull the side push rod 85 to rotate clockwise. After the side push rod 85 rotates clockwise, one end of the side push rod 85 can pull the first longitudinal sealing plate 88 to move left, and the other end of the side push rod 85 can push the second longitudinal sealing plate 89 to move right, so as to quickly perform the longitudinal sealing operation on the transversely sealed material strip.

[0093] In some embodiments, more specifically, a shear cylinder 891 is arranged on the first longitudinal sealing plate 88, and the output end of the shear cylinder 891 can penetrate into the first longitudinal sealing plate 88. A cutter is also provided in the first longitudinal sealing plate 88, and the cutter is connected to the output end of the shear cylinder 891; after completing the longitudinal sealing operation of the material strip, by turning on the switch of the shear cylinder 891, the cutter on the output end of the shear cylinder 891 can be driven to cut off the longitudinally sealed material strip, so as to facilitate the subsequent continuous horizontal and vertical sealing operations of the material strip.

[0094] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
