Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and in particular to a press-type device and method for removing the packaging film from cigarette cartons. Background Technology

[0002] Currently, when producing the Lotus series of uniquely shaped cigarettes, cigarette manufacturers rely on manual removal of the outer packaging film from the carton during the carton feeding process. This manual removal of the carton packaging film is labor-intensive, inefficient, and prone to damaging the carton.

[0003] In view of this, the prior art provides an apparatus for removing the outer packaging bag of a carton:

[0004] Application No. 202222869206.0 discloses a carton outer packaging bag removal device, which specifically includes a conveyor belt I, a telescopic material-grabbing assembly, and a conveyor belt II. The telescopic material-grabbing assembly includes a telescopic rod, a pull rod rotatably connected to the end of the telescopic rod, a driving component for driving the telescopic rod to move back and forth, and a carton channel located below the starting point of the telescopic rod. The carton channel includes an adjusting frame for adjusting the width of the carton channel and a rough chamfer block located inside the adjusting frame. Existing technology utilizes the frictional difference between the packaging film and the rough chamfer block and the carton as the carton passes through the carton channel to break and remove the packaging film. However, in this method, excessive pressure applied by the rough chamfer block to the carton can cause scratches on the surface of the carton, or even tear the carton. Furthermore, the pressure applied by the rough chamfer block to the carton weakens as the spring tension decreases, easily resulting in the inability to completely peel off and remove the packaging film from the carton. Summary of the Invention

[0005] In view of this, the present invention provides a device and method for pressing to remove the packaging film of a carton, which can solve the technical problem in the prior art that the excessive pressure applied by the rough chamfered block to the carton causes scratches on the surface of the carton, or even tears the carton. It can also solve the technical problem in the prior art that long-term use will lead to a decrease in the performance of the components, making it impossible to completely peel off and remove the packaging film of the carton.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A pressing-type device for removing packaging film from carton boxes includes a belt conveyor I and a belt conveyor II arranged parallel to the belt conveyor I and in the opposite direction to its conveying direction. A film bag removal device is mounted on top of the belt conveyor I and the belt conveyor II via a bracket. The bracket includes a front frame and a rear frame arranged parallel to it, and a plurality of transverse support rods are connected between the front frame and the rear frame. The film bag removal device removes the packaging film from the carton boxes during transport. It includes a telescopic transport mechanism, a pressing mechanism spanning above the telescopic transport mechanism, and a carton channel located below the pressing mechanism.

[0008] The telescopic transfer mechanism includes a telescopic rod, a driving component I for extending and retracting the telescopic rod, and a pull rod connected to the end of the telescopic rod. The outer surface of the driving component I is provided with a fixed bracket I and a fixed bracket II. A pull rod guard net is provided on the side end of the bracket. The pressing mechanism includes a connecting frame, a pressing block provided at the end of the connecting frame, and a driving component II for pressing the connecting frame up and down. The strip box channel includes a channel support plate, a strip box inlet opened at the side end of the channel support plate, and a release silicone provided at the strip box inlet. The channel support plate is provided with a work area and a transition area located beside it. A box stop is provided between the pressing mechanism and the strip box inlet. The box stop is provided with a connecting end and a blocking end.

[0009] When the packaging film is removed, drive component I drives the telescopic rod to retract from its initial extended state, while drive component II drives the clamping block at the end of the connecting frame to press it into contact with the carton packaging film. The packaging film is peeled off by utilizing the frictional difference between the packaging film, the carton, and the clamping block. As the telescopic rod further pushes the carton into the carton inlet, the release silicone on the inside of the carton inlet comes into contact with the carton and is squeezed. The frictional difference between the packaging film, the carton, and the release silicone can ensure the complete peeling of the carton packaging film for the second time.

[0010] Furthermore, the belt conveyor I is provided with a conveying end I and an output end I, and the belt conveyor II is provided with a conveying end II and an output end II. The output end I of the belt conveyor I is flush with the conveying end II of the belt conveyor II, so that the film bag removal device is supported above the output end I of the belt conveyor I and the conveying end II of the belt conveyor II. This allows the strip box transported to the output end I of the belt conveyor I to be transferred to the conveying end II of the belt conveyor II under the action of the film bag removal device and further transported to the output end II of the belt conveyor II.

[0011] Furthermore, the bracket provides support for the film bag removal device. The left and right ends of the front and rear frames are respectively connected to the outer ends of belt conveyor I and belt conveyor II. The transverse support rods are respectively connected to the telescopic transfer mechanism, the pressing mechanism, and the box stop.

[0012] Furthermore, the telescopic transfer mechanism can transfer the strip box from the output end I of belt conveyor I to the conveying end II of belt conveyor II. The fixed bracket I is connected to the left end of the bracket through a connecting piece, and the fixed bracket II is connected to the middle end of the bracket through a box stop. The pull rod includes a fixed plate and material-picking hooks mirror-arranged at its left and right ends. The telescopic rod passes through the front end face of the fixed plate to the rear end face of the fixed plate and the fixed plate is fastened to the front end of the telescopic rod with a nut. The material-picking hook can rotate with its connection point with the fixed plate as the center, so that the material-picking hook can be in a raised or lowered state.

[0013] Preferably, the driving component I is a cylinder.

[0014] Furthermore, the tie rod guard net serves to protect the tie rod from damage, and the tie rod guard net is provided around the bottom and sides of the tie rod in the extended state.

[0015] Furthermore, the pressing mechanism can press and contact the packaging film and, under the action of the telescopic transfer mechanism, peel off the packaging film by utilizing the frictional difference between the packaging film and the carton and the pressing block; the connecting frame is configured as an inverted "U" shape, which spans across the top of the drive component I, the top of the connecting frame is connected to the drive component II, the drive component II is connected to the bracket through a cylinder connecting plate, and the drive component II can drive the connecting frame to move towards or away from the carton; the bottom of the connecting frame is provided with a pressing block.

[0016] Preferably, the drive component II is a twin-shaft cylinder of model TN-16X20-S.

[0017] Preferably, the clamping block is made of silicone, which can increase the friction between the carton packaging film and the pressing mechanism, and also prevent the carton surface from being scratched or torn.

[0018] Furthermore, the carton channel not only provides a transfer path for the carton from belt conveyor I to belt conveyor II, but also serves as a secondary guarantee for the smooth peeling of the packaging film. A vertical partition is provided at the side end of the transition zone of the channel support plate. The carton inlet is located on the surface of the vertical partition. The inner edge of the carton inlet is wrapped with a release silicone in an inverted "U" shape. When the carton passes through the carton inlet, the inner side of the release silicone contacts and is compressed against the carton surface. The frictional difference between the packaging film, the carton, and the release silicone further ensures the complete peeling of the carton packaging film. A guide rod is provided on the upper surface of the transition zone, corresponding to the bottom side of the release silicone. The guide rod forms an "eight"-shaped guide channel in the transition zone that connects to the carton inlet. A positioning baffle I is provided at the front end of the workstation area. A positioning baffle II is provided at the front end of the vertical partition. A channel connecting plate is provided on the bottom surface of the channel support plate, connecting to the inner side of belt conveyor II.

[0019] Furthermore, a material detection device is provided on the inner side of the positioning baffle I. When the strip box is within the detection distance of the material detection device, the material detection device transmits a signal to the film bag removal device to push the strip box and press to remove the film.

[0020] Furthermore, a funnel-shaped negative pressure suction port is provided above the carton channel to suck up the peeled carton packaging film. The negative pressure is achieved by using compressed air based on the Venturi principle.

[0021] Furthermore, the box stop has the function of preventing strip boxes that are not in contact with the pressing mechanism from being carried into the transition area of ​​the channel support plate by the strip boxes on its adjacent side that are in contact with the pressing mechanism. The connecting end of the box stop is sleeved on the outside of the fixed bracket II of the driving component I and connected to the bracket. The blocking end of the box stop is located above the junction of the working area and the transition area of ​​the channel support plate, and is used to prevent strip boxes that are not in contact with the pressing mechanism from entering the transition area of ​​the channel support plate and affecting the normal demolding operation.

[0022] The present invention also provides a method for using a press-type strip box packaging film removal device, which can be applied to the above-mentioned press-type strip box packaging film removal device, and the specific steps include:

[0023] S1: Belt conveyor I transports the carton from its conveying end I to its output end I. The carton is blocked by the positioning baffle I located at the front end of the channel support plate work area. The positioning baffle I causes the cartons entering the work area to be stacked tightly in a row at the output end of belt conveyor I, so as to facilitate the push of the telescopic transfer mechanism. At this time, the telescopic rod of the telescopic transfer mechanism is in the extended state, the material picking hook is in the lowered state, and the pressing block at the bottom of the connecting frame in the pressing mechanism is not in contact with the carton packaging film.

[0024] S2: In step S1, when the material detection device located inside the positioning baffle I detects the carton within the detection distance, the material detection device transmits signals to the drive component I of the telescopic transfer mechanism and the drive component II of the pressing mechanism to activate them. When the drive component I drives the telescopic rod to retract from its initial extended state and then drives the pull rod to move towards the carton, the end of the picking hook is directly opposite the center position of the side of the carton. As the telescopic rod retracts, the end of the picking hook contacts the side surface of the carton and pushes the carton from the working area of ​​the channel support plate to the transition area. At the same time, the drive component II can drive the connecting frame to move towards the carton. The direction of the movement causes the bottom surface of the pressing block to press and contact the carton packaging film. Because the friction between the carton packaging film and the pressing block of the pressing mechanism is greater than the friction between the carton packaging film and the carton surface, the carton packaging film is successfully peeled off through the friction difference between the packaging film, the carton, and the pressing block. The peeled packaging film is sucked up by the negative pressure suction port set above the carton channel and stored in the designated position. During this period, the box stop located above the junction of the working area and the transition area of ​​the channel support plate prevents the carton that is not in contact with the pressing block from being brought into the transition area of ​​the channel support plate by the carton that is in contact with the pressing block on its adjacent side.

[0025] S3: In step S2, the carton pushed from the station area of ​​the channel support plate to the transition area by the telescopic transfer mechanism, passes through the figure-eight shaped guide channel formed by the guide rod in the transition area and is connected to the carton entrance, and continues to be pushed into the carton entrance. When the carton passes through the carton entrance, the inner side of the release silicone comes into contact with the carton surface and is squeezed. Because the friction between the carton packaging film and the release silicone is greater than the friction between the carton packaging film and the carton surface, the friction difference between the packaging film and the carton and the release silicone further ensures the complete peeling of the carton packaging film. The carton with the packaging film peeled off is finally transferred to the conveyor end II of the belt conveyor II.

[0026] Compared with the prior art, the technical solution of this invention has the following beneficial effects:

[0027] 1. This invention features a reasonable structural design, low manufacturing cost, and high work efficiency. By setting a pressing mechanism to press and contact the carton packaging film, and under the action of the telescopic transfer mechanism pushing the carton, the frictional difference between the packaging film and the carton, and the pressing block of the pressing mechanism, ensures the smooth peeling of the carton packaging film. Then, when the telescopic transfer mechanism continues to push the carton through the carton inlet, the inner side of the release silicone comes into contact with the carton surface and is squeezed. The frictional difference between the packaging film and the carton, and the release silicone further ensures the complete peeling of the carton packaging film. This achieves a high degree of automation in the removal of packaging film from irregularly shaped cigarette cartons. Furthermore, the setting of the pressing block of the pressing mechanism and the release silicone at the carton inlet avoids scratches on the carton surface when pressure is applied to the carton, or even damage to the carton, saving labor costs and protecting the workshop production environment.

[0028] 2. The present invention provides a guide rod on the upper end face of the transition area of ​​the channel support plate to guide the carton to enter the carton smoothly. It forms an "eight"-shaped guide channel in the transition area that communicates with the carton entrance. The cooperation between the carton entrance and the guide channel can ensure that the carton does not tip over after the packaging bag is removed.

[0029] 3. By setting a box stop, the present invention can prevent the strip box that is not in contact with the pressing mechanism from entering the transition area of ​​the channel support plate by the strip box on its adjacent side that is in contact with the pressing mechanism, thus affecting the normal demolding operation.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figures 1 to 8 As shown, Embodiment 1 of the present invention provides a device for pressing and removing the packaging film of a carton.

[0044] It includes a belt conveyor I1 and a belt conveyor II2 arranged parallel to the side of belt conveyor I1 and opposite to its conveying direction. A film bag removal device is mounted above belt conveyor I1 and belt conveyor II2 via a bracket 3. The bracket 3 includes a front frame 31 and a rear frame 32 arranged parallel to it. Several transverse support rods 33 are connected between the front frame 31 and the rear frame 32. The film bag removal device has the function of removing the packaging film of the carton during the transfer of the carton. It includes a telescopic transfer mechanism 4, a pressing mechanism 5 spanning above the telescopic transfer mechanism 4, and a carton channel 6 located below the pressing mechanism 5.

[0045] The telescopic transfer mechanism 4 includes a telescopic rod 41, a driving component I 42 for extending and retracting the telescopic rod 41, and a pull rod 43 connected to the end of the telescopic rod 41. The outer surface of the driving component I 42 is provided with a fixed bracket I 421 and a fixed bracket II 422. The side end of the bracket 3 is provided with a pull rod guard net 7. The pressing mechanism 5 includes a connecting frame 51, a pressing block 52 provided at the end of the connecting frame 51, and a driving component II 53 for pressing the connecting frame 51 up and down. The carton channel 6 includes a channel support plate 61, a carton inlet 63 opened at the side end of the channel support plate 61, and a release silicone 64 provided at the carton inlet 63. The channel support plate 61 is provided with a work area and a transition area located beside it. A carton stop 8 is provided between the pressing mechanism 5 and the carton inlet 63. The carton stop 8 is provided with a connecting end and a blocking end.

[0046] When the packaging film is removed, the drive component I 42 drives the telescopic rod 41 to retract from its initial extended state. At the same time, the drive component II 53 drives the clamping block 52 at the end of the connecting frame 51 to press and contact the packaging film of the carton. The packaging film is peeled off by utilizing the frictional difference between the packaging film, the carton, and the clamping block 52. When the telescopic rod 41 further pushes the carton into the carton inlet 63, the release silicone 64 on the inside of the carton inlet 63 contacts the carton and is squeezed. The frictional difference between the packaging film, the carton, and the release silicone 64 can ensure the complete peeling of the carton packaging film for the second time.

[0047] In Embodiment 1 of the present invention, belt conveyor I1 is provided with conveying end I and output end I, and belt conveyor II2 is provided with conveying end II and output end II. The output end I of belt conveyor I1 is flush with the conveying end II of belt conveyor II2, so that the film bag removal device is mounted on the support 3 above the output end I of belt conveyor I1 and the conveying end II of belt conveyor II2, thereby enabling the strip box transported to the output end I of belt conveyor I1 to be transferred to the conveying end II of belt conveyor II2 under the action of the film bag removal device and further transported to the output end II of belt conveyor II2.

[0048] The bracket 3 provides support for the film bag removal device. The left and right ends of the front frame 31 and the rear frame 32 are connected to the outer ends of the belt conveyor I1 and the belt conveyor II2, respectively. The transverse support rods 33 are connected to the telescopic transfer mechanism 4, the pressing mechanism 5 and the box stop 8, respectively. Specifically, there are three transverse support rods 33, namely transverse support rod I, transverse support rod II and transverse support rod III. Transverse support rod I is connected to the tail end of the telescopic transfer mechanism 4, transverse support rod II is connected to the box stop 8 and transverse support rod III is connected to the pressing mechanism 5.

[0049] The telescopic transfer mechanism 4 can transfer the strip box from the output end I of belt conveyor I1 to the conveying end II of belt conveyor II2. The driving component I 42 is a cylinder. The fixed bracket I 421 is connected to the left end of the bracket 3 through a connecting piece. The fixed bracket II 422 is connected to the middle end of the bracket 3 through the box stop 8. Specifically, the fixed bracket I 421 is connected to the transverse support rod I through a connecting piece, and the fixed bracket II 422 is connected to the transverse support rod II through the connecting end of the box stop 8. The pull rod 43 includes a fixed plate 431 and material-picking hooks 432 mirror-arranged at its left and right ends. The telescopic rod 41 passes through the front end face of the fixed plate 431 to the rear end face of the fixed plate 431 and the fixed plate 431 is fastened to the front end of the telescopic rod 41 with a nut. The material-picking hook 432 can rotate around the connection point with the fixed plate 431, so that the material-picking hook 432 can be in a raised or lowered state, and the distance between the two mirror-set picking hooks 432 is the thickness of three cartons. When the picking hook 432 is in the lowered state, the lateral end of the picking hook 432 is parallel to the telescopic rod 41, and the end of the picking hook 432 is directly facing the center position of the side of the carton, so as to ensure that the two cartons pass through the carton channel 6 smoothly at the same time. The telescopic rod 41 is normally and initially in the extended state so that the carton can be transported by the belt conveyor I1 to the station area of ​​the channel support plate 61 to wait for the next action. When the driving component I 42 drives the telescopic rod 41 to extend and retract, and then drives the pull rod 43 to move towards the carton, the end of the picking hook 432 contacts the side surface of the carton and pushes the carton from the station area of ​​the channel support plate 61 through the transition area and the carton inlet 63 to the belt conveyor II 2.

[0050] The tie rod guard 7 serves to protect the tie rod 43 from damage, and the tie rod guard 7 is arranged around the bottom and sides of the tie rod 43 in the extended state;

[0051] The pressing mechanism 5 can press and contact the packaging film, and under the action of the telescopic transfer mechanism 4, it can peel off the packaging film by utilizing the frictional difference between the packaging film and the carton and the pressing block 52; the connecting frame 51 is set as an inverted "U" shaped structure, which spans across the top of the drive component I 42. The top of the connecting frame 51 is connected to the drive component II 53. The drive component II 53 adopts a dual-axis cylinder of model TN-16X20-S. The drive component II 53 is connected to the bracket 3 through the cylinder connecting plate. The drive component II 53 can drive the connecting frame 51 to move towards or away from the carton; the bottom of the connecting frame 51 A clamping block 52 is provided, which is made of silicone. This material can increase the friction between the carton packaging film and the pressing mechanism 5, and also prevent the carton surface from being scratched or torn. When the driving component II 53 can drive the connecting frame 51 to move towards the carton and make the bottom surface of the clamping block 52 press and contact the carton packaging film, the friction between the carton packaging film and the clamping block 52 of the pressing mechanism 5 is greater than the friction between the carton packaging film and the carton surface. The friction difference between the packaging film and the carton and the clamping block 52 ensures the smooth peeling of the carton packaging film.

[0052] The carton channel 6 not only provides a transfer path for cartons from belt conveyor I1 to belt conveyor II2, but also serves as a secondary guarantee for the smooth peeling of the packaging film. A vertical partition 62 is provided on the side of the transition area of ​​the channel support plate 61. Carton inlets 63 are located on the surface of the vertical partition 62, and each carton inlet 63 allows passage of a longitudinally placed carton. The inner edge of the carton inlet 63 is wrapped with a release silicone 64 in an inverted "U" shape. When a carton passes through the carton inlet 63, the inner side of the release silicone 64 contacts and is compressed against the carton surface. Because the friction between the carton packaging film and the release silicone 64 is greater than the friction between the carton packaging film and the carton surface, the difference in friction between the packaging film, the carton, and the release silicone 64 further ensures complete peeling of the carton packaging film. A guide rod 65 is provided on the upper surface of the transition area, corresponding to the bottom side of the release silicone 64, guiding... Rod 65 provides guidance for the carton to smoothly enter the carton inlet 63. It forms an "eight"-shaped guide channel in the transition area that connects with the carton inlet 63. The cooperation between the carton inlet 63 and the guide channel ensures that the carton does not tip over after the packaging bag is removed. A positioning baffle I 66 is set at the front end of the work area. The positioning baffle I 66 makes the cartons entering the work area stacked tightly in a row at the output end of the belt conveyor I 1, which facilitates the smooth entry of the cartons into the guide channel and then being transferred to the belt conveyor II 2 through the carton inlet 63. A positioning baffle II 67 is set at the front end of the vertical partition 62. The positioning baffle II 67 can prevent the cartons transferred to the belt conveyor II 2 from slipping off from the opposite direction of its conveying direction. The bottom end of the channel support plate 61 is provided with a channel connecting plate 68 that connects to the inner side of the belt conveyor II 2. The side of the channel support plate 61 away from the carton inlet 63 is connected to the outer edge of the belt conveyor I 1.

[0053] A material detection device is provided on the inner side of the positioning baffle I66. When the strip box is within the detection distance of the material detection device, the material detection device transmits a signal to the film bag removal device to push the strip box and press to remove the film.

[0054] Above the carton channel 6 is a funnel-shaped negative pressure suction port, which is used to suck up the peeled carton packaging film. The negative pressure is achieved by using compressed air based on the Venturi principle.

[0055] The box stop 8 serves to prevent strip boxes that are not in contact with the pressing mechanism 5 from being carried into the transition area of ​​the channel support plate 61 by the strip boxes on its adjacent side that are in contact with the pressing mechanism 5. The connecting end of the box stop 8 is sleeved on the outside of the fixed bracket II 422 of the drive component I 42 and connected to the bracket 3. The blocking end of the box stop 8 is located above the junction of the working area and the transition area of ​​the channel support plate 61, and is used to prevent strip boxes that are not in contact with the pressing mechanism 5 from entering the transition area of ​​the channel support plate 61, thus affecting the normal demolding operation.

[0056] Example 2

[0057] The present invention also provides a method for using a press-type strip box packaging film removal device, which can be applied to the above embodiment 1, and the specific steps include:

[0058] S1: Belt conveyor I1 transports the carton from its conveying end I to its output end I. The carton is blocked by the positioning baffle I66 located at the front end of the station area of ​​the channel support plate 61. The positioning baffle I66 causes the cartons entering the station area to be stacked tightly in a row at the output end of the belt conveyor I1, so as to facilitate the push of the telescopic transfer mechanism 4. At this time, the telescopic rod 41 of the telescopic transfer mechanism 4 is in the extended state, the material hook 432 is in the lowered state, and the pressing block 52 at the bottom of the connecting frame 51 in the pressing mechanism 5 is not in contact with the carton packaging film.

[0059] S2: In step S1, when the material detection device located inside the positioning baffle I 66 detects the carton within the detection distance, the material detection device transmits signals to the drive member I 42 of the telescopic transfer mechanism 4 and the drive member II 53 of the pressing mechanism 5 to activate them. When the drive member I 42 drives the telescopic rod 41 to retract from its initial extended state and then drives the pull rod 43 to move towards the carton, the end of the picking hook 432 is directly opposite the center position of the side of the carton. As the telescopic rod 41 retracts, the end of the picking hook 432 contacts the side surface of the carton and pushes the carton from the working area of ​​the channel support plate 61 to the transition area. At the same time, the drive member II 53 can drive the connecting frame 51. The mechanism moves towards the carton and presses the bottom surface of the pressing block 52 into contact with the carton packaging film. Because the friction between the carton packaging film and the pressing block 52 of the pressing mechanism 5 is greater than the friction between the carton packaging film and the carton surface, the carton packaging film is successfully peeled off due to the difference in friction between the packaging film, the carton, and the pressing block 52. The peeled packaging film is sucked up by the negative pressure suction port provided above the carton channel 6 and stored in a designated location. During this period, the box stop 8 located above the junction of the working area and the transition area of ​​the channel support plate 61 prevents the carton that is not in contact with the pressing block 52 from being brought into the transition area of ​​the channel support plate 61 by the carton that is in contact with the pressing block 52 on its adjacent side.

[0060] S3: In step S2, the carton pushed from the station area of ​​the channel support plate 61 to the transition area by the telescopic transfer mechanism 4, passes through the figure-eight shaped guide channel formed by the guide rod 65 in the transition area and is connected to the carton inlet 63, and continues to be pushed into the carton inlet 63. When the carton passes through the carton inlet 63, the inner side of the release silicone 64 contacts the carton surface and is squeezed. Because the friction between the carton packaging film and the release silicone 64 is greater than the friction between the carton packaging film and the carton surface, the friction difference between the packaging film and the carton and the release silicone 64 further ensures the complete peeling of the carton packaging film. The carton with the packaging film peeled off is finally transferred to the conveying end II of the belt conveyor II2.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The support includes a front frame and a rear frame arranged parallel to it, and several transverse support rods are connected between the front frame and the rear frame; the film bag removal device has the function of removing the packaging film of the strip box when transferring the strip box, and includes a telescopic transfer mechanism, a pressing mechanism spanning above the telescopic transfer mechanism, and a strip box channel located below the pressing mechanism. The telescopic transfer mechanism can transfer the strip box from the output end I of belt conveyor I to the conveying end II of belt conveyor II. The telescopic transfer mechanism includes a telescopic rod, a driving component I for extending and retracting the telescopic rod, and a pull rod connected to the end of the telescopic rod. The outer surface of the driving component I is provided with a fixed bracket I and a fixed bracket II. The fixed bracket I is connected to the left end of the bracket through a connecting piece. The pull rod includes a fixed plate and material-picking hooks mirror-arranged at its left and right ends. The telescopic rod passes through the front end face of the fixed plate to the rear end face of the fixed plate and the fixed plate is fastened to the front end of the telescopic rod with a nut. The material-picking hook can rotate with its connection point with the fixed plate as the center, so that the material-picking hook can be in a raised or lowered state. The pressing mechanism includes a connecting frame, a pressing block disposed at the end of the connecting frame, and a driving component II that drives the connecting frame to press up and down. The pressing mechanism can press and contact the packaging film and peel off the packaging film by utilizing the friction difference between the packaging film and the carton and the pressing block under the action of the telescopic transfer mechanism. The connecting frame is configured as an inverted "U" shape, which spans above the head end of the driving component I. The top end of the connecting frame is connected to the driving component II. The driving component II is connected to the bracket through a cylinder connecting plate. The driving component II can drive the connecting frame to move towards or away from the carton. A pressing block is disposed at the bottom end of the connecting frame. The carton channel not only provides a transfer path for the cartons from belt conveyor I to belt conveyor II, but also serves to ensure the smooth peeling of the packaging film. The carton channel includes a channel support plate, a carton inlet located at the side of the channel support plate, and silicone release agent placed at the carton inlet. The channel support plate is provided with a work area and a transition area located beside it. A box stop is provided between the pressing mechanism and the box inlet. The box stop is provided with a connecting end and a blocking end. The fixed bracket II is connected to the middle of the bracket through the box stop. A pull rod guard is provided on the side of the bracket. When the packaging film is removed, drive component I drives the telescopic rod to retract from its initial extended state, while drive component II drives the clamping block at the end of the connecting frame to press it into contact with the carton packaging film. The packaging film is peeled off by utilizing the frictional difference between the packaging film, the carton, and the clamping block. As the telescopic rod further pushes the carton into the carton inlet, the release silicone on the inside of the carton inlet comes into contact with the carton and is squeezed. The frictional difference between the packaging film, the carton, and the release silicone can ensure the complete peeling of the carton packaging film a second time.

4. The device for pressing and removing the packaging film of a carton according to claim 1, characterized in that: The clamping block is made of silicone, which increases the friction between the carton packaging film and the pressing mechanism, and also prevents the carton surface from being scratched or torn.

5. The device for pressing and removing the packaging film of a carton according to claim 1, characterized in that: A vertical partition is provided on the side of the transition area of ​​the channel support plate. The carton inlet is opened on the surface of the vertical partition. The inner edge of the carton inlet is wrapped with a release silicone with an inverted "U" shape. When the carton passes through the carton inlet, the inner side of the release silicone contacts the carton surface and is squeezed. The friction difference between the packaging film, the carton, and the release silicone further ensures the complete peeling of the carton packaging film. The upper end of the transition area is provided with guide rods that are connected to the bottom side of the release silicone. The guide rods form an "eight"-shaped guide channel in the transition area that communicates with the carton inlet. A positioning baffle I is provided at the front end of the workstation area. A positioning baffle II is provided at the front end of the vertical partition. A channel connecting plate that connects to the inner side of the belt conveyor II is provided on the bottom end of the channel support plate.

6. The device for pressing and removing the packaging film of a carton according to claim 1, characterized in that: Above the carton channel is a funnel-shaped negative pressure suction port for sucking up the peeled carton packaging film. The negative pressure is achieved using compressed air based on the Venturi principle.

7. The device for pressing and removing the packaging film of a carton according to claim 1, characterized in that: The box stop has the function of preventing strip boxes that are not in contact with the pressing mechanism from being carried into the transition area of ​​the channel support plate by the strip boxes on its adjacent side that are in contact with the pressing mechanism. The connecting end of the box stop is sleeved on the outside of the fixed bracket II of the driving component I and connected to the bracket. The blocking end of the box stop is located above the junction of the working area and the transition area of ​​the channel support plate, and is used to prevent strip boxes that are not in contact with the pressing mechanism from entering the transition area of ​​the channel support plate and affecting the normal demolding operation.

8. A method of using a press-type strip box packaging film removal device, wherein the method is applied to the press-type strip box packaging film removal device according to any one of claims 1 to 7, characterized in that: The specific steps include: S1: Belt conveyor I transports the carton from its conveying end I to its output end I. The carton is blocked by the positioning baffle I located at the front end of the channel support plate work area. The positioning baffle I causes the cartons entering the work area to be stacked tightly in a row at the output end of belt conveyor I, so as to facilitate the push of the telescopic transfer mechanism. At this time, the telescopic rod of the telescopic transfer mechanism is in the extended state, the material picking hook is in the lowered state, and the pressing block at the bottom of the connecting frame in the pressing mechanism is not in contact with the carton packaging film. S2: In step S1, when the material detection device located inside the positioning baffle I detects the carton within the detection distance, the material detection device transmits signals to the drive component I of the telescopic transfer mechanism and the drive component II of the pressing mechanism to activate them. When the drive component I drives the telescopic rod to retract from its initial extended state and then drives the pull rod to move towards the carton, the end of the picking hook is directly opposite the center position of the side of the carton. As the telescopic rod retracts, the end of the picking hook contacts the side surface of the carton and pushes the carton from the working area of ​​the channel support plate to the transition area. At the same time, the drive component II can drive the connecting frame to move towards the carton. The direction of the movement causes the bottom surface of the pressing block to press and contact the carton packaging film. Because the friction between the carton packaging film and the pressing block of the pressing mechanism is greater than the friction between the carton packaging film and the carton surface, the carton packaging film is successfully peeled off through the friction difference between the packaging film, the carton, and the pressing block. The peeled packaging film is sucked up by the negative pressure suction port set above the carton channel and stored in the designated position. During this period, the box stop located above the junction of the working area and the transition area of ​​the channel support plate prevents the carton that is not in contact with the pressing block from being brought into the transition area of ​​the channel support plate by the carton that is in contact with the pressing block on its adjacent side. S3: In step S2, the carton pushed from the station area of ​​the channel support plate to the transition area by the telescopic transfer mechanism, passes through the figure-eight shaped guide channel formed by the guide rod in the transition area and is connected to the carton entrance, and continues to be pushed into the carton entrance. When the carton passes through the carton entrance, the inner side of the release silicone comes into contact with the carton surface and is squeezed. Because the friction between the carton packaging film and the release silicone is greater than the friction between the carton packaging film and the carton surface, the friction difference between the packaging film and the carton and the release silicone further ensures the complete peeling of the carton packaging film. The carton with the packaging film peeled off is finally transferred to the conveyor end II of belt conveyor II.
