[0060] Among them, the film feeding mechanism 10 is used for clamping the plastic film, opening the plastic sealing venting hole, ensuring the plastic film feeding, tightening and measuring the film feeding length, and preparing for subsequent work; the punching and labeling mechanism 20 is used to separate the double-layer plastic film folded in the process of transportation, and to open a tear hole at the place where it needs to be unsealed, so as to facilitate tearing when the film is unsealed. At the same time, in order to ensure the effect of plastic sealing and make it easy for the final customer to find the unsealing point, the marked label is flatly attached to the unsealing place; the flipping mechanism 30 includes a first flipping component 31 and a second flipping component 32. The first flipping component 31 flips the plastic film with holes punched and labels attached, and flips one side of the attached label to the inner side of the double-layer plastic film folded in half; the lifting component 33 is used to adjust the distance between the flipping templates of the second flipping component 32, which is well adapted to the changes in the specifications of books and periodicals and the size of plastic sealing. The second flipping component 32 flips the plastic film for the second time during the transportation process, so that the plastic film will be the front transmission during the transportation process. The objects to be packaged transported by the conveying mechanism 40 are wrapped, and the affixed tear labels are turned over to the outside of the packages to facilitate identification when unpacking; the front conveying mechanism 40 is used to receive the books or other objects to be packaged processed in the previous stage, and transport the objects to be packaged into the plastic film for wrapping; the sealing and cutting mechanism 50 is used to cut the plastic film wrapped around the objects to be packaged front and back and heat-seal the upper and lower layers of film together to complete the rear side packaging of the front side package and the front side packaging of the next package; the rear conveying mechanism 60 is used to receive the sealed and cut packages, transport them to the side sealing mechanism 70 to complete the side sealing, and transport the plastic-sealed packages to the next process; the side sealing mechanism 70 is installed on one side of the rear conveying mechanism 60, and is used for hot-melt sealing of the sides of the plastic-sealed objects and cutting off excess plastic film; a residual film collecting mechanism 80 is provided on the other side of the side sealing mechanism 70, which is used to collect the residual plastic film generated during the operation of the side sealing mechanism 70.

[0061] refer to Figure 3-5 As shown, the film feeding mechanism 10 includes a film feeding box 101, a film supporting roller 102, a first film guide roller 103, a second film guide roller 104, a perforated film supporting roller 105, a puncturing and releasing hole assembly 106, a third film guide roller 107, a film feeding roller 108, a film pressing roller 109, a film tensioning rocker arm assembly 110, a tensioning fixed roller 111, a length measuring transmission roller 112, a length measuring pressing assembly 113, a fourth film guide roller 114, a film feeding motor 115, a length measuring sensor 116, and a film blocking rod 117.

[0062] The film feeding mechanism 10 includes a film feeding box 101, a film supporting roller 102, a first film guide roller 103, a second film guide roller 104, a perforated film supporting roller 105, a puncture and release hole assembly 106, a third film guide roller 107, a film feeding roller 108, a film pressing roller 109, a tensioning film swing rod assembly 110, a tensioning fixed roller 111, a length measuring transmission roller 112, a length measuring pressing assembly 113, a fourth film guide roller 114, a film feeding motor 115, a length measuring sensor 116, and a film blocking rod 117. Each mechanism is installed on the film feeding box 101, and the film feeding box 101 is the basis for connecting various parts. The film supporting roller 102 is used to support the plastic film 118. By adjusting the position of the film blocking rod 117, it can adapt to the clamping and positioning of plastic films 118 of different specifications. After the plastic film 118 is clamped on the film support roller 102, it passes the first film guide roller 103 and the second film guide roller 104, and then goes to the pierced film support roller 105, and cooperates with the several piercing and venting hole components 106 to evenly pierce plastic sealing and venting holes on the plastic film 118, which is convenient for the subsequent hot plastic sealing process. After the plastic film 118 with venting holes passes through the third film guide roller 107, it passes through the middle of the film feeding roller 108 and the film pressing roller 109. The film feeding roller 108 is connected to the film feeding motor 115. By controlling the rotation speed of the film feeding motor 115, different film feeding speeds are achieved. The plastic film 118 is sent out at different speeds under the rolling of the film feeding roller 108 and the film pressing roller 109. The delivered plastic film 118 passes by the film guide roller on the tension swing arm assembly and the tension fixed roller 111, and then reaches the middle of the length-counting transmission roller 112 and the pressing roller of the length-counting pressing assembly 113, and then reaches the fourth film guide roller 114 and is delivered. The tension film swing arm assembly 110 detects the speed of film delivery through the angle change caused by stretching the plastic film 118, and adjusts the speed of the film delivery motor 115. After the plastic film 118 is pressed by the film pressing roller 109 of the length-counting pressing assembly 113, it is tightly attached to the length-counting transmission roller 112, driving the length-counting transmission roller 112 to rotate synchronously with the movement of the plastic film 118 and transmit it to the length-counting sensor 116 connected thereto, so as to detect the conveying distance of the plastic film 118 and provide a basis for the control of the subsequent punching and labeling process.

[0063] Reference Figure 6-8 As shown, the punching and labeling mechanism 20 includes an adjustable support component 21, a bottom plate 22, a punching component 23, a film separation component 24, and a labeling component 25.

[0064] The labeling assembly 25 includes a material hanging plate 251, a film guide rod group 252, a first film pressing assembly 253, a film pulling wheel 254, a film pulling motor 255, a label separation plate 256 assembly, a second film pressing assembly 257, a labeling support plate 258, a film collecting belt 259, a film collecting roller 260, a film separation assembly 24, a label material sensor 262, and a label position sensor 261. The film guide rod group 252 includes a first film guide rod, a second film guide rod, and a third film guide rod, and the traveling direction of the material belt is changed by the first film guide rod, the second film guide rod, and the third film guide rod. The film separation assembly 24 includes a film separation rod 241 and a film separation wheel 242, and the film separation wheel 242 is rotatably installed at one end of the film separation rod 241, and the film separation rod 241 is adjustably installed on the bottom plate 22.

[0065] Among them, the adjustable support assembly 21 is used as a mounting base, and the other parts are directly or indirectly fixed on the adjustable support assembly 21, and can be moved and fixed along the guide shaft of the support mechanism to adapt to plastic films 118 of different specifications. The bottom plate 22 is the basis of the punching and labeling mechanism 20, and the other components are connected as a whole through the bottom plate 22. The punching assembly 23 is a core functional mechanism of the punching and labeling mechanism 20. Together with the film separation assembly 24 connected with it, it completes the separation of the double-layer plastic film 118 and the punching function of the plastic film 118 unsealing hole. After the plastic film 118 is sent to the film separation assembly 24 through the length-metered film delivery box 101, the film separation assembly 24 extends to the center of the double-layer film, and completes the film separation function during the forward conveying of the plastic film 118. The film separation assembly 24 can be telescopically adjusted to adapt to plastic films 118 of different specifications. One side of the separated plastic film 118 passes through the middle groove of the punching assembly 23 and the middle groove of the labeling support plate 258 and is transported to the flipping mechanism 30. During this period, the punching assembly 23 is used to make holes and the labeling support plate 258 is used to complete the labeling and unsealing functions. The punching assembly 23 drives the hole-making tool 232 through the hole-making cylinder 231 to make holes at the position where holes are needed. The hanging plate 251 assembly is a card loading mechanism for the unsealed label to be pasted, and it is adapted to label rolls of different specifications through two adjustable position blocking plates at the front and rear. The label roll follows the film winding trajectory, first passes through the first film guide rod, the second film guide rod, and the third film guide rod, and then passes through the pressure roller of the first film pressing assembly 253 and the film pulling wheel 254. After reaching the stripping plate of the labeling support plate 258 assembly, it is wound on the material collecting shaft of the waste film collecting mechanism for waste film collection. The label material sensor 262 installed between the second film guide rod and the third film guide rod detects whether the label roll to be pasted is used up, so as to remind the operator to change the material in time; the pressure roller of the first film pressing assembly 253 is connected to the film pulling motor 255. After the pressure roller of the first film pressing assembly 253 presses the label material strip, the film pulling motor 255 rotates, driving the label material strip to move forward synchronously, and at the same time, the film collection belt 259 drives the film collection roller 260 to rotate, collects and wraps the waste strip together for easy collection. After the material strip passes through the label separation plate 256 assembly, when the front end of the label separation plate 256 makes a sharp turn, the label is peeled off along the tangent direction of the label separation plate 256, and is synchronously sent to the middle of the labeling support plate 258 and the pressure roller of the second film pressing assembly 257 with the collection of the material strip, and is rolled by the pressure roller and adhered to the labeling position of the plastic film 118 passing synchronously. The label position sensor 261 is used to sense the position of the label, and together with the length sensor 116, controls the start, stop and speed change of the film feeding motor 115 to achieve accurate labeling at the required position.

[0066] Reference Figure 9-10As shown, the flip mechanism 30 includes a first flip assembly 31, a second flip assembly 32, a lifting assembly 33, a middle split assembly 34 and a horizontal adjustment assembly 35. The first flip assembly 31 is composed of two symmetrical flip templates, and the upper and lower flip templates are respectively installed on separate fixed frames. After the plastic film passing through the punching labeling mechanism 20 passes through the first flip assembly 31, it bypasses the upper and lower flip templates from the outside, turns 90 degrees, and flips the labeled label to the inside of the double-layer plastic film to the second flip assembly 32. The second flip assembly 32 repeats the above operation, and flips the label that was flipped to the inside for the first time to the outside, which is convenient for operation identification during unpacking. The upper and lower flip templates of the second flip assembly 32 are respectively fixed on the upper moving mechanism and the lower fixing mechanism of the lifting assembly 33. By adjusting the hand wheel of the lifting assembly 33, the upper flip template is driven to move up and down to adapt to packages of different thicknesses. The plastic film middle split assembly 34 separates the double-layer plastic film relative to the upper and lower templates. The film separation pulley at the front end of the middle split assembly 34 can be adjusted to adapt to plastic films of different specifications. The lifting assembly 33 is integrally connected to the front conveying mechanism 40 . By adjusting the hand wheel of the horizontal adjustment assembly 35 , the lifting assembly 33 and the second flip assembly 32 are driven by the lead screw to move together to adapt to plastic films and packaging materials of different specifications.

[0067] Reference Figure 11-12 As shown, the front conveying mechanism 40 includes a front conveyor belt bracket 41, a first conveyor belt 42, a packaging guide component 43, a self-locking component 44, a fixed bracket 45, and a first driving motor 46; the front conveyor belt bracket 41 is the basis of the front conveying mechanism 40, and other parts are connected as a whole through this component. The front conveyor belt bracket 41 and the slide rail supported below move horizontally together under the drive of the horizontal adjustment component 35. The lower flip template of the second flip component 32 can extend to the lower side of the first conveyor belt 42, so that the plastic film is covered on the upper and lower sides of the first conveyor belt 42 after the second flip. When the contemporary packaging is transported forward by the first conveyor belt 42 out of the front conveying mechanism 40 along the guide plate of the packaging guide component 43, it is wrapped up and down by the plastic film that is synchronously stretched forward. The self-locking component 44 is fixed on the front conveyor belt bracket 41, and is connected to the fixed bracket 45 through the self-locking hook of the self-locking component 44. When the handle of the self-locking component 44 is pulled, the hook is opened, and the connection with the fixed bracket 45 is opened, so that the front conveying mechanism 40 can be moved alone by pulling the handle at the front end, which is convenient for operation and maintenance and debugging. The fixed bracket 45 is connected to the lifting component 33 and the second flip component 32, and is connected to it as a whole when the self-locking component 44 is in the self-locking state. The first drive motor 46 is the power source of the front conveying mechanism 40, driving the start, stop and speed regulation of the front conveying mechanism 40.

The upright column of the sealing and cutting support 51 is a guide rail for the upper sealing and cutting blade 53 and the lower sealing and cutting blade 54 to move. The sealing and cutting blade adjustment assembly 52 is used to adjust the height of the upper sealing and cutting blade 53, the lower sealing and cutting blade 54 and the sealing and cutting blade drive assembly 55 to adapt to packaging of different specifications. By rotating the hand wheel of the sealing and cutting blade adjustment assembly 52, the transmission shaft is driven, and then transmitted to the lifting adjustment screw through the chain, thereby driving the sealing and cutting blade drive assembly 55 to move up and down. The sealing and cutting blade drive assembly 55 is driven to move as a whole through the driving swing rods of the upper sealing and cutting blade 53 and the lower sealing and cutting blade 54. The sealing and cutting blade drive assembly 55 is the power source for the movement of the upper sealing and cutting blade 53 and the lower sealing and cutting blade 54. The reduction drive motor of the sealing and cutting knife driving assembly 55 drives the output shaft, and then the swing rod fixed on the output shaft drives the connecting rods of the upper sealing and cutting knife 53 and the lower sealing and cutting knife 54 respectively. The output shaft driven by the reduction drive motor reciprocates, thereby driving the swing rod to swing, and the upper sealing and cutting knife 53 and the lower sealing and cutting knife 54 are driven to open and close through the connecting rod, thereby realizing the sealing and cutting function.

[0069] Reference Figure 15-16 As shown, the rear conveying mechanism 60 includes a rear conveying bracket 61, a second conveying belt 62, a second driving motor 63 and a driving shaft 64. The rear conveying bracket 61 is the main body of the rear conveying mechanism 60, and other components are connected as a whole through the rear conveying bracket 61. The second conveying belt 62 is a carrier for carrying and transporting packaging materials, and the second driving motor 63 is the power source of the mechanism, driving the driving shaft 64 to transmit power to the second conveying belt 62 and the side sealing mechanism 70, so that the two parts move synchronously.

[0070] Reference Figure 17-18 As shown, the side sealing mechanism 70 includes a side cutting bracket 71, a driving sprocket 72, a transmission chain 73, an upper conveyor belt assembly 74, a lower conveyor belt assembly 75, a side cutting adjustment assembly 76, and a side cutting knife 77. The side cutting bracket 71 is used to connect the side sealing mechanism 70 with the rear conveying mechanism 60 shown, and connect the other parts of the mechanism as a whole. The driving sprocket 72 is fixed on Figure 7On the driving shaft 64 shown, the power is transmitted to the side sealing mechanism 70 through the transmission chain 73 and the transmission gears on the reverse sides of the upper conveyor belt assembly 74 and the lower conveyor belt assembly 75, so that the upper conveyor belt assembly 74 and the lower conveyor belt assembly 75 start and stop synchronously with the rear conveying mechanism 60. When it starts, the heated side cutter 77, under the driving pressure of the internal cylinder, cuts off the residual edge of the continuously moving plastic film and completes the heat sealing. After stopping, the side cutter 77 automatically lifts up to avoid scalding the plastic film. The side cutting adjustment assembly 76 is used to adjust the side cutting mechanism up and down to adapt to packages of different thicknesses. Turning the hand wheel on the upper part of the side cutting adjustment assembly 76 drives the connected lead screw to drive the entire part to move up and down.

[0071] Reference Fig.19 As shown, the residual film collection mechanism 80 includes a residual film box 81, a film guide wheel 82, a residual film blocking plate 83, a residual film collection shaft 84, a residual film bracket 85, a film-winding counterweight swing rod 86, a film-collecting motor 87, and a swing rod detection sensor 88. Among them, the residual film box 81 is a protective cover of the residual film collection mechanism 80, and has an openable protective door on the outside to facilitate the operator to debug and remove the residual film. The film guide wheel 82 is used to guide the residual film cut off by the side sealing mechanism 70 into the residual film box 81 to make it move smoothly. The residual film blocking plate 83 is used to block the residual film on the residual film collection shaft 84 to prevent it from overflowing. The residual film bracket 85 is used to connect other components to make them integrated. The film-winding counterweight swing rod 86 and the swing rod detection sensor 88 are used together to detect the tension of the residual film when it is collected, and use this information to control the speed of the film-collecting motor 87 to prevent the residual film from being stretched too tight or too loose. The film collecting motor 87 is used to control the start, stop and rotation speed of the residual film collecting shaft 84. After deceleration, the film collecting motor 87 transmits this movement to the residual film collecting shaft 84 through chain and sprocket transmission to complete the residual film collection.

[0072] The residual film collecting mechanism 80 maintains tension on the residual film at all times by setting a film-wrapped counterweight swing rod 86, so that the residual film can be more smoothly wound around the film collecting disk during the collection process; a motor and a chain are used for power transmission, with high transmission efficiency, low noise, and saving installation space; one end of the collecting shaft passes through the shell, and the film-wrapped material blocking disk can be easily removed from the collecting shaft, so that it can be replaced after it is full; the overall structure is compact, and it runs in a closed box, which is safe and stable.

[0073] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
