[0055] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

[0060] Currently, for easy transportation, cartons or rolls of tubular products are typically wrapped with film, then secured with support panels using packing tape. However, before these cartons or rolls are stored or shipped out for use, the packaging, including the packaging tape, support panel covers, and film, must be removed.

[0061] In the prior art, the removal of outer packaging typically involves manual handling and the individual removal of packaging straps, support plate covers, and outer film. This complicates the disassembly and assembly process, is prone to safety incidents, and lacks intelligent automation. Removal of outer packaging is a major pain point, particularly in the tobacco industry.

[0062] Based on the above ideas and problems, the present invention proposes a packaging unpacking device 100. It can be understood that the packaging unpacking device 100 can realize the full automatic unpacking of the outer packaging of the package to be unpacked. The product to be unpacked is generally a carton or a cylindrical product. A plurality of cartons or cylindrical products are wrapped and combined into one body by an outer film, so that the multiple products can be fixed as one and the products can be prevented from being damaged. Then, the multiple cartons or cylindrical products wrapped as one are placed on a support plate structure to realize the placement, storage and positioning of the multiple cartons or cylindrical products. The support plate structure usually includes two plate-like structures arranged opposite to each other, namely a bottom plate and an upper cover. The bottom plate and the upper cover are arranged at the opposite ends of the multiple cylindrical products wrapped as one. In order to fix the bottom plate and the upper cover with the multiple cylindrical products wrapped as one, they are usually bundled together with a packaging belt, which can be convenient for handling and transportation.

[0063] In this embodiment, the unpacking device 100 is required to remove the packaging belt, the upper cover of the support plate structure, and the outer film of the unpacked product to facilitate the circulation of multiple cylindrical products. It is understandable that the unpacking device 100 can be applied to the tobacco industry and other industries, without limitation here.

[0064] Please refer to Figures 1 to 12 As shown, in an embodiment of the present invention, the unpacking device 100 includes a body 1, a tape cutting mechanism 2, a cover opening mechanism 3 and a film cutting mechanism 4, wherein the body 1 is provided with a conveying channel 11, and the conveying channel 11 is sequentially formed with a tape cutting station, a cover opening station and a film cutting station along its extension direction. The conveying channel 11 is used to convey the packaged objects to be unpacked, and the tape cutting mechanism 2 includes a support frame 21, a power device 22 and a fixed cutting device 23. The support frame 21 is arranged adjacent to the conveying channel 11 and forms a cutting space 211 corresponding to the tape cutting station. The power device 22 is arranged on the support frame 21, and the fixed cutting device 23 includes a fixed cutting device 23 and a fixed cutting device 23. The fixed component 231 and the cutter component 232 are connected, the cutter component 232 is connected to the fixed component 231, the power device 22 drives the fixed component 231 to move into the cutting space 211 to fix the package to be unpacked at the tape cutting station, and the cutter component 232 cuts the packaging tape of the package to be unpacked, the cover opening mechanism 3 is arranged adjacent to the conveying channel 11 and corresponding to the cover opening station, the cover opening mechanism 3 is used to remove the upper cover of the package to be unpacked at the cover opening station, the film cutting mechanism 4 is arranged adjacent to the conveying channel 11 and corresponding to the film cutting station, the film cutting mechanism 4 is used to cut off the outer film of the package to be unpacked at the film cutting station.

[0065] In this embodiment, the body 1 is used to mount, secure, or support the ribbon cutting mechanism 2, lid opening mechanism 3, and film cutting mechanism 4. It will be appreciated that the body 1, ribbon cutting mechanism 2, lid opening mechanism 3, and film cutting mechanism 4 are integrally configured. Of course, the body 1 and the ribbon cutting mechanism 2, lid opening mechanism 3, and film cutting mechanism 4 can also be separate components. To facilitate production, transportation, and assembly, the body 1, ribbon cutting mechanism 2, lid opening mechanism 3, and film cutting mechanism 4 can optionally be separate components.

[0066] As will be appreciated, the machine body 1 is provided with a conveying passage 11 for conveying the packages to be unpacked. In this embodiment, the machine body 1 is provided with a conveyor belt, a transmission roller, a transfer belt, or a chain, etc., which form the conveying passage 11 for conveying the packages to be unpacked. Any structure capable of conveying the packages to be unpacked is acceptable and is not limited herein.

[0067] In this embodiment, the ribbon cutting mechanism 2 further includes a detection and control device (not shown), which can be mounted on the support frame 21 and electrically connected to the power unit 22. The detection and control device is used to detect the position of the package to be unpacked and control the operation of the power unit 22. It is understood that the power unit 22 can be configured as a cylinder, a motor, or other structure capable of driving the fixed assembly 231 to move, without specific limitation.

[0068] It is understood that by configuring the fixed cutting device 23 as a fixed assembly 231 and a cutter assembly 232, the fixed assembly 231 is connected to the output end of the power device 22 and is movably connected to the support frame 21, so that the power device 22 can be used to drive the fixed assembly 231 to move relative to the support frame 21. The cutter assembly 232 is movably connected to the fixed assembly 231 and is electrically connected to the detection and control device, so that the detection and control device controls the movement of the cutter assembly 232 relative to the fixed assembly 231 and realizes cutting of the packaging tape of the unpacked package at the tape cutting station in the cutting space 211.

[0069] After the detection and control device detects that the packaged object wrapped with the packaging tape has entered the cutting space 211, it controls the power device 22 to drive the fixing assembly 231 to extend into the cutting space 211 and move toward the packaged object until the fixing assembly 231 abuts and presses against the outer wall of the packaged object, thereby tightening the packaging tape against the outer wall of the packaged object and preventing it from shifting. The detection and control device then controls the cutter assembly 232 to move relative to the fixing assembly 231 to cut the tightened packaging tape. By providing the fixing assembly 231, the packaging tape can be tightened and straightened before cutting, preventing it from shifting, facilitating the cutting of the packaging tape by the cutter assembly 232, and preventing scratches on the packaged object when cutting the packaging tape, effectively improving cutting efficiency.

[0070] In this embodiment, a cover opening mechanism 3 and a film cutting mechanism 4 are respectively provided corresponding to the cover opening station and the film cutting station, so that the cover opening mechanism 3 is used to remove the upper cover of the package to be unpacked that is transported to the cover opening station and has the packaging tape cut off, and the film cutting mechanism 4 is used to cut the outer film of the package to be unpacked that is transported to the film cutting station and has the upper cover removed, so that the outer packaging of the product to be unpacked is completely removed.

[0071] It is understood that the tape cutting mechanism 2, lid opening mechanism 3, and film cutting mechanism 4 of the unpacking device 100 work in sequence, that is, the unpacked items on the conveying channel 11 of the body 1 are conveyed to the tape cutting station, lid opening station, and film cutting station in sequence, and the tape cutting, upper cover removal, and outer film removal operations are performed in sequence. In this embodiment, the unpacking device 100 is provided with a control center or controller or control circuit or control board with integrated control program, etc. The control center or controller or control circuit or control board with integrated control program, etc., are electrically connected to the conveying structure of the body 1, the power device 22 and cutter assembly 232 of the tape cutting mechanism 2, the lid opening mechanism 3, and the film cutting mechanism 4, thereby controlling the operation of the conveying structure of the body 1, the power device 22 and cutter assembly 232 of the tape cutting mechanism 2, the lid opening mechanism 3, and the film cutting mechanism 4.

[0072] The unpacking device 100 of the present invention is provided with a conveying channel 11 on the body 1, and a tape cutting station, a cover opening station and a film cutting station are sequentially formed in the conveying channel 11 along its extension direction, so that the packaged objects to be unpacked are sequentially conveyed to the tape cutting station, the cover opening station and the film cutting station by the conveying channel, and the corresponding outer packaging objects are removed; the tape cutting mechanism 2 is provided with a support frame 21, a power device 22 and a fixed cutting device 23, so that the power device 22 and the fixed cutting device 23 are installed and fixed by the support frame 21, so that the power device 22 drives the fixed component 231 of the fixed cutting device 23 to move into the cutting space 211, The package to be unpacked at the tape cutting station is fixed, and the packaging tape of the package to be unpacked is cut by the cutting assembly 232; the cover opening mechanism 3 and the film cutting mechanism 4 are further matched with the cover opening station and the film cutting station on the conveying channel respectively, so that the cover opening mechanism 3 is used to remove the upper cover of the package to be unpacked at the cover opening station, and the film cutting mechanism 4 is used to cut off the outer film of the package to be unpacked at the film cutting station, so as to complete the removal of all outer packaging of the package to be unpacked, so that the outer packaging can be fully automatically removed without manual handling and disassembly, and automatic disassembly and assembly can be realized, which effectively avoids the occurrence of safety accidents, effectively reduces labor costs, and improves work efficiency and intelligence.

[0073] In one embodiment, the fixing assembly 231 includes a frame fixing portion 2311 and a top corner fixing portion 2315, wherein the frame fixing portion 2311 includes a first connecting member 2312 connected to the power device 22 and a frame pressure plate 2313, the frame pressure plate 2313 is connected to the side of the first connecting member 2312 facing away from the power device 22, the cutter assembly 232 is movably connected to the first connecting member 2312, the top corner fixing portion 2315 is located around the frame fixing portion 2311, the top corner fixing portion 2315 includes a second connecting member 2316 connected to the power device 22 and a top corner pressure plate 2317, the top corner pressure plate 2317 is connected to the side of the second connecting member 2316 facing away from the power device 22.

[0074] As can be understood, the upper cover of the package to be unpacked includes a middle portion and an edge portion. The edge portion is connected to the middle portion and is raised relative to the middle portion. That is, the upper cover of the package to be unpacked has a high edge and a low middle portion. The packaging strap of the package to be unpacked is wrapped around the upper cover and stretched by the edge portion so that the packaging strap is spaced apart from the middle portion.

[0075] In this embodiment, if Figures 3 to 5 As shown, the power unit 22 includes a first cylinder and a second cylinder. The first cylinder and the second cylinder are both connected to the support frame 21. The connection can be via screws or other feasible methods, which are not specifically limited. The output end of the first cylinder is connected to the frame fixing portion 2311. The cutter assembly 232 is movably connected to the frame fixing portion 2311. The output end of the second cylinder is connected to the top corner fixing portion 2315.

[0076] As will be understood, after the packaged object is conveyed to the cutting space 211, the frame fixing portion 2311 and the top corner fixing portion 2315 are both located above the packaged object. The detection and control device controls the second cylinder to drive the top corner fixing portion 2315 to extend into the cutting space 211 and move toward the packaged object. After the top corner fixing portion 2315 abuts and presses against the top corner of the edge of the packaged object, the detection and control device controls the first cylinder to drive the frame fixing portion 2311 to extend into the cutting space 211 and move toward the packaged object until the frame fixing portion 2311 abuts and presses against the edge of the packaged object. The frame fixing portion 2311 presses the packaging tape against the edge. Since both sides of the packaging tape are pressed against the edge, the middle section of the packaging tape becomes taut and suspended above the middle section, preventing the packaging tape from shifting. The detection and control device controls the cutter assembly 232 to move above the middle section to cut the taut packaging tape.

[0077] By providing the top corner fixing portion 2315 to press against the top corners of the packaged object to be opened, the position of the packaged object to be opened can be fixed, preventing the packaged object from shifting. By providing the frame fixing portion 2311, the packaging belt is pressed against the edge of the packaged object to be opened, so that the packaging belt can be stretched and suspended above the middle portion, leaving a certain distance between the packaging belt and the middle portion, making it easier for the cutter assembly 232 to cut the packaging belt and effectively preventing the cutter assembly 232 from scratching the packaged object when cutting the packaging belt, thereby improving the efficiency of cutting and unpacking.

[0078] In this embodiment, the first connecting member 2312 of the frame fixing portion 2311 is connected to the output end of the first cylinder so as to drive the first connecting member 2312 to move via the first cylinder. The cutter assembly 232 is movably connected to the first connecting member 2312 and can move along the first connecting member 2312. The frame pressing plate 2313 is connected to the side of the first connecting member 2312 facing away from the first cylinder. The frame pressing plate 2313 and the first connecting member 2312 can be configured to be detachably connected to facilitate the later inspection and replacement of parts. The frame pressing plate 2313 is configured to be a polygonal ring so that the crisscrossing packaging straps can be pressed tightly against the edge of the upper cover of the package to be removed.

[0079] It can be understood that after the top corner fixing portion 2315 abuts against and presses against the top corner of the edge of the package to be unpacked, the detection and control device controls the first cylinder to drive the first connecting member 2312 to move toward the cutting space 211, and the first connecting member 2312 drives the frame pressure plate 2313 and the cutter assembly 232 to extend into the cutting space 211 until the frame pressure plate 2313 abuts against the edge of the package to be unpacked, so as to press the packaging belt to the edge through the frame pressure plate 2313. Since the two sides of the packaging belt are pressed against the edge, the middle section of the packaging belt will be tightened and suspended above the middle part. The detection and control device controls the cutter assembly 232 to move along the first connecting member 2312 to cut the packaging belt tightened above the middle part.

[0080] By providing a first connecting member 2312 connected between the first cylinder and the frame pressing plate 2313, the frame pressing plate 2313 and the cutter assembly 232 can be driven to move simultaneously. By providing the frame pressing plate 2313 and configuring the frame pressing plate 2313 in a ring shape, both sides of the packaging strap can be pressed tightly against the edge portion 6 of the upper cover of the package to be removed. The pressure exerted by each side of the frame pressing plate 2313 on the edge portion is equal, so that the force on both sides of the packaging strap is evenly applied, and the packaging strap is prevented from being pulled out between the frame pressing plate 2313 and the edge portion when squeezed, thereby facilitating the cutting of the packaging strap.

[0081] In one embodiment, if Figure 5As shown, a first protrusion 2314 is provided on the side of the frame pressing plate 2313 facing away from the first connecting member 2312. It is understood that there are four first protrusions 2314, which are arranged in pairs opposite to each other and distributed on different sides of the frame pressing plate 2313. The extended lines of the arrangement directions of the four first protrusions 2314 intersect to form a square, so that the four first protrusions 2314 can fit the edge portion.

[0082] It can be understood that by providing the first protrusion 2314, the packaging belt can be better pressed against the edge portion, avoiding the existence of a gap between the frame pressure plate 2313 and the edge portion, enhancing the tightening effect of the packaging belt, and improving cutting efficiency.

[0083] In this embodiment, one side of the second connecting member 2316 of the corner fixing portion 2315 is connected to a corner pressure plate 2317. This second connecting member 2316 is movably connected to the support frame 21, serving as a guide. The corner pressure plate 2317 is connected to the output end of the second cylinder. Both ends of the corner pressure plate 2317 are provided with a 90° bend, allowing the corner pressure plate 2317 to conform to the corner edge of the package to be unpacked.

[0084] As can be understood, the second cylinder drives the top corner pressure plate 2317 to move, and at the same time, the second connecting member 2316 follows the top corner pressure plate 2317 to extend into the cutting space 211 and move toward the package to be unpacked. After the top corner pressure plate 2317 abuts and presses against the top corner of the edge of the package to be unpacked, the first cylinder drives the first connecting member 2312 to drive the frame pressure plate 2313 and the cutter assembly 232 to extend into the cutting space 211, and the first protrusion 2314 first contacts the packaging tape and the edge portion on the side facing away from the frame pressure plate 2313, and under the driving action of the first cylinder, the first protrusion 2314 presses the packaging tape against the edge portion, and the two first protrusions 2314 press against the two sides of the packaging tape, and the middle section of the packaging tape will be tightened and suspended above the middle portion, and the detection and control device controls the cutter assembly 232 to cut the packaging tape tightened above the middle portion.

[0085] The second connector 2316 guides the top corner pressing plate 2317, allowing it to move vertically and abut against the top corner of the edge. The top corner pressing plate 2317 presses against the top corner of the edge, thereby securing the position of the package to be unpacked and facilitating the frame pressing plate 3122 to tighten and straighten the packaging tape, thereby improving cutting efficiency.

[0086] In one embodiment, if Figure 5As shown, a second protrusion 2318 is provided on the side of the top corner pressure plate 2317 facing away from the second connecting member 2316. It is understood that there are two second protrusions 2318, which are arranged side by side along the direction in which the top corner pressure plate 2317 is arranged. The second protrusions 2318 abut against the outer wall of the package to be opened, thereby limiting the position of the package to be opened, preventing the package from shifting, and facilitating cutting of the packaging strap.

[0087] In one embodiment, if Figure 5 As shown, there are two top corner fixing portions 2315 , and the two top corner fixing portions 2315 are oppositely arranged on both sides of the frame fixing portion 2311 .

[0088] It can be understood that by setting two top corner fixing parts 2315 on the opposite sides of the frame fixing part 2311, the second protrusions 2318 of the two top corner fixing parts 2315 abut against the outer walls on the opposite sides of the package to be unpacked, thereby limiting the position of the package to be unpacked, fixing the position of the package to be unpacked, facilitating the cutting of the packaging tape, and improving the cutting efficiency.

[0089] In one embodiment, the cutter assembly 232 includes a shell 2321 and a pressing and cutting portion 2323, wherein the shell 2321 is movably connected to the fixed assembly 231, the shell 2321 is formed with a cutting groove 2322, and the pressing and cutting portion 2323 includes a driving member 2324, a pressing member 2325 and a cutting member 2326. The driving member 2324 is arranged on the side of the shell 2321 facing away from the cutting groove 2322. The driving member 2324 is connected to the pressing member 2325 to drive the pressing member 2325 to extend into the cutting groove 2322 to press the packaging tape into the cutting groove 2322. The cutting member 2326 is connected to the driving member 2324 and is arranged parallel to the pressing member 2325 to cut the packaging tape.

[0090] In this embodiment, Figure 6 and Figure 7 As shown, the housing 2321 is movably connected to the first connecting member 2312, providing installation, support, and protection. The compression and cutting portion 2323 is disposed within the housing 2321, and is driven by the housing 2321 to move to the location of the packaging strip to be cut. The housing 2321 and the compression and cutting portion 2323 are both electrically connected to a detection and control device. The cutting slot 2322 is used to accommodate the packaging strip, and the three adjacent side walls of the cutting slot 2322 each have an opening to facilitate the entry of the packaging strip into the cutting slot 2322. At least a portion of the compression and cutting portion 2323 can extend into the cutting slot 2322 and can move vertically relative to the housing 2321, thereby pressing the packaging strip within the cutting slot 2322 against the bottom wall of the cutting slot 2322, thereby preventing the broken packaging strip from bouncing and scattering. In other embodiments, the cutter assembly 232 provided herein can also cut other strips, without specific limitation.

[0091] As can be understood, the opening of the side wall of the cutting groove 2322 is aligned with the packaging tape to be cut, and the housing 2321 is controlled to move relative to the first connecting member 2312, so that the packaging tape to be cut enters the cutting groove 2322. At least a portion of the pressing and cutting portion 2323 extends into the cutting groove 2322 to press the packaging tape against the bottom wall of the cutting groove 2322 and cut the packaging tape. By providing the above-mentioned pressing and cutting portion 2323, the packaging tape can be pressed against the cutting groove 2322 before being cut. Since the packaging tape is always pressed against the cutting groove 2322, the broken packaging tape will not be scattered, which facilitates unified recycling and effectively improves the efficiency of packaging tape cutting.

[0092] In this embodiment, Figure 7 As shown, the driving member 2324 is disposed within the housing 2321 and is located on the side of the housing 2321 facing away from the cutting groove 2322. The driving member 2324 is electrically connected to the detection and control device for providing power. The pressing member 2325 is disposed within the housing 2321 and is connected to the driving member 2324. Through the transmission cooperation between the driving member 2324 and the pressing member 2325, the pressing member 2325 is driven to extend into the cutting groove 2322, thereby compressing the packaging strap within the cutting groove 2322 to prevent the packaging strap from shifting. The cutting member 2326 is arranged in the shell body 2321 and is connected to the driving member 2324. The cutting member 2326 and the pressing member 2325 are arranged in parallel. The pressing member 2325 and the cutting member 2326 have the same movement direction. Through the transmission cooperation between the driving member 2324 and the cutting member 2326, the cutting member 2326 is driven to extend into the cutting groove 2322 to cut the packaging tape in the cutting groove 2322.

[0093] As can be understood, the driving member 2324 drives the pressing member 2325 toward the cutting groove 2322, causing the pressing member 2325 to extend into the cutting groove 2322. The pressing member 2325, with its side facing away from the driving member 2324, presses the packaging strip to be cut against the bottom wall of the cutting groove 2322 to secure the packaging strip. Simultaneously, the driving member 2324 drives the cutting member 2326 toward the cutting groove 2322, causing the cutting member 2326 to extend into the cutting groove 2322. The cutting member 2326, with its side facing away from the driving member 2324, cuts the packaging strip to be cut. Since the pressing member 2325 always presses the packaging strip against the bottom wall of the cutting groove 2322, not only is cutting easier for the cutting member 2326, but the cut packaging strip will not be scattered. Therefore, by setting the clamping piece 2325, the position of the packaging tape can be fixed, which facilitates the cutting piece 2326 to cut the packaging tape. Under the clamping action of the clamping piece 2325, the packaging tape can be prevented from shifting, preventing the broken packaging tape from being scattered, and facilitating recycling and processing.

[0094] Optionally, the driving member 2324 includes a third cylinder, a third connecting member, and a fourth connecting member. The third cylinder is disposed within the housing 2321, the third connecting member is connected between the third cylinder and the cutting member 2326, and the fourth connecting member is connected between the third connecting member and the pressing member 2325. In this embodiment, the third cylinder is connected to the housing 2321 and is located on a side of the housing 2321 facing away from the cutting groove 2322. The output end of the third cylinder faces the housing 2321 and is capable of extending into the housing 2321. The third connecting member is located within the housing 2321 and is connected between the output end of the third cylinder and the cutting member 2326. The third cylinder drives the third connecting member to move, thereby driving the cutting member 2326 toward the cutting groove 2322 through the third connecting member. The fourth connecting member is located in the shell 2321 and is connected between the third connecting member and the clamping member 2325 to drive the third connecting member to move through the third cylinder, and then drive the fourth connecting member to move through the third connecting member, and drive the clamping member 2325 to move toward the cutting groove 2322 through the fourth connecting member.

[0095] It is understood that the distance between the end of the pressing member 2325 facing the cutting groove 2322 and the bottom wall of the cutting groove 2322 is smaller than the distance between the end of the cutting member 2326 facing the cutting groove 2322 and the bottom wall of the cutting groove 2322. Therefore, when the third cylinder drives the third connecting member to move toward the cutting groove 2322, the end of the pressing member 2325 facing away from the fourth connecting member can first extend into the cutting groove 2322, contact the packaging strip to be cut, and press the packaging strip against the bottom wall of the cutting groove 2322. Furthermore, under the further driving action of the third cylinder, the end of the cutting member 2326 facing away from the third connecting member extends into the cutting groove 2322 and cuts the packaging strip.

[0096] The third connecting member is fixedly connected to the cutting member 2326, and the fourth connecting member is fixedly connected between the third connecting member and the pressing member 2325 to improve the stability of the installation. In other embodiments, the third connecting member and the third cylinder can be detachably connected, the third connecting member and the cutting member 2326 can be detachably connected, and the third connecting member and the fourth connecting member can be detachably connected, such as by snapping, screwing, or other feasible methods, which are not specifically limited, to facilitate the subsequent maintenance and replacement of parts.

[0097] It can be understood that the third cylinder drives the third connecting member to move toward the cutting groove 2322, and the third connecting member drives the fourth connecting member and the cutting member 2326 to move toward the cutting groove 2322, and then drives the clamping member 2325 through the fourth connecting member to extend into the cutting groove 2322 relative to the cutting member 2326, and presses the packaging tape to be cut against the bottom wall of the cutting groove 2322. Under the further driving action of the third cylinder, the third connecting member drives the cutting member 2326 to extend into the cutting groove 2322 and cut the packaging tape.

[0098] Under the continuous action of the third cylinder, the pressing member 2325 presses the severed packaging strap into the cutting groove 2322, and the severed packaging strap is transported to a designated location by moving the housing 2321. Once the severed packaging strap arrives at the designated location, the third cylinder drives the third connecting member to move away from the cutting groove 2322, thereby driving the fourth connecting member and the cutting member 2326 to move away from the cutting groove 2322. The fourth connecting member then drives the pressing member 2325 away from the bottom wall of the cutting groove 2322, thereby loosening the severed packaging strap and allowing the packaging strap to be uniformly recycled. The provision of the third cylinder can drive the third and fourth connecting members to move, thereby driving the pressing member 2325 and the cutting member 2326 toward or away from the cutting groove 2322, thereby achieving compression and cutting of the packaging strap.

[0099] In one embodiment, if Figure 7 As shown, the pressing member 2325 includes a pressing block, a telescopic rod, and a spring. The telescopic rod is connected between the fourth connecting member and the pressing block, and the spring is mounted on the telescopic rod and abuts between the pressing block and the fourth connecting member. It is understood that the pressing block is arranged along the axial direction of the third cylinder, and the telescopic rod is connected between the fourth connecting member and the pressing block, so that the distance between the pressing block and the fourth connecting member is adjustable. The spring is mounted on the telescopic rod and abuts between the pressing block and the fourth connecting member to enhance the squeezing effect of the pressing block on the packaging strip to be cut. The distance between the end of the pressing block facing away from the telescopic rod and the bottom wall of the cutting groove 2322 is less than the distance between the end of the cutting member 2326 facing away from the third connecting member and the bottom wall of the cutting groove 2322, allowing the pressing block to extend into the cutting groove 2322 before the cutting member 2326.

[0100] As can be understood, the third cylinder drives the third connecting member to move toward the cutting groove 2322, which in turn drives the fourth connecting member and the cutting member 2326 toward the cutting groove 2322. The fourth connecting member then drives the pressing block to extend into the cutting groove 2322. The side of the pressing block facing away from the telescopic rod first contacts the packaging strip to be cut, pressing the packaging strip against the bottom wall of the cutting groove 2322. Under the further driving action of the third cylinder, the distance between the fourth connecting member and the pressing block decreases, the telescopic rod contracts, and the spring is squeezed by the fourth connecting member and deformed. The elastic force of the spring increases the pressing effect of the pressing block on the packaging strip, preventing the packaging strip from shifting. Simultaneously, the third connecting member drives the cutting member 2326 to extend into the cutting groove 2322 and cut the packaging strip.

[0101] Under the continuous action of the third cylinder, the pressing block presses the broken packaging tape into the cutting groove 2322. After being transferred to the designated position, the third cylinder drives the third connecting member to move back to the cutting groove 2322, so as to drive the fourth connecting member and the cutting member 2326 to move back to the cutting groove 2322, and then drives the telescopic rod to restore to its initial length through the fourth connecting member. Under the further driving action of the third cylinder, the pressing block is pulled up through the telescopic rod to move the pressing block away from the cutting groove 2322, thereby loosening the cut packaging tape and uniformly recycling the packaging tape.

[0102] By providing a telescopic rod, the distance between the fourth connecting member and the pressing block is adjustable. Thus, when the pressing block abuts against the bottom wall of the cutting groove 2322, the third cylinder can further drive the third connecting member to move toward the cutting groove 2322. By providing a spring, when the spring is deformed, it can generate elastic force to act on the pressing block, thereby increasing the pressure of the pressing block on the packaging strap and improving the compression effect on the packaging strap.

[0103] In one embodiment, if Figure 7 As shown, the cutting member 2326 includes a top block and a cutting knife. The top block is connected to the third connecting member and is arranged in parallel with the pressing member 2325. The cutting knife is connected to the side of the top block facing away from the third connecting member. It can be understood that the top block is arranged along the axial direction of the third cylinder, and the top block is connected to the side of the third connecting member facing away from the third cylinder and is located on one side of the pressing block. The cutting knife is connected to the side of the top block facing away from the third connecting member, and the blade of the cutting knife faces the cutting groove 2322 and protrudes relative to the top block to facilitate cutting of the packaging tape. The cutting knife and the top block can be set to a detachable connection, such as a snap connection, a screw connection, or other achievable methods, without specific limitation, to facilitate the later maintenance and replacement of parts.

[0104] It is understood that after the pressure block, facing away from the telescopic rod, presses the packaging tape against the bottom wall of the cutting groove 2322, the third connecting member drives the top block toward the cutting groove 2322 under the further driving action of the third cylinder, and then drives the cutting blade toward the cutting groove 2322 through the top block, and extends into the cutting groove 2322 to cut the packaging tape. After the movable housing 2321 is moved to the designated position, the third cylinder drives the third connecting member to move away from the cutting groove 2322, and the third connecting member drives the top block to move away from the cutting groove 2322, so that the cutting blade first moves away from the cutting groove 2322. During the continuous driving process of the third cylinder, the fourth connecting member drives the pressure block away from the cutting groove 2322 through the telescopic rod, thereby loosening the cut packaging tape and uniformly recycling the packaging tape.

[0105] In one embodiment, if Figure 6 and Figure 7As shown, the shell 2321 includes a first shell and a second shell, an active cavity is formed in the first shell, the driving member 2324 is connected to the first shell, the pressing member 2325 and the cutting member 2326 are located in the active cavity, the second shell is connected to the first shell, and is surrounded by the first shell to form a cutting groove 2322, and the active cavity is connected to the cutting groove 2322.

[0106] In this embodiment, the first shell and the second shell can be set to be detachably connected, for example, by passing a screw through the second shell and the first shell in sequence, and then installing and connecting the second shell and the first shell, or other achievable methods are all acceptable, without specific limitation, to facilitate the later inspection and replacement of parts.

[0107] Optionally, the second housing is provided with a through hole, which faces the cutting member 2326. By providing the through hole, after the cutting knife cuts the packaging tape, the side of the cutting knife facing away from the top block can extend into the through hole, providing a buffer space for the cutting knife to protect the cutting edge of the cutting knife, avoid damage to the cutting knife, and effectively extend the service life of the cutting knife.

[0108] Alternatively, as Figure 6 As shown, a first guide surface is formed on the side of the first shell facing the second shell, and a second guide surface is formed on the side of the second shell facing the first shell. It will be understood that the first guide surface and the second guide surface are arranged opposite each other, with the opening of the cutting groove 2322 formed therebetween. Furthermore, the distance between the first guide surface and the second guide surface gradually decreases in the direction toward the cutting groove 2322, so that the cutting groove 2322 has a wide opening to guide the packaging strap.

[0109] It can be understood that when the packaging tape to be cut contacts the first guide surface or the second guide surface, both the first guide surface and the second guide surface can guide the packaging tape, so that the packaging tape can slide smoothly into the cutting groove 2322, thereby improving the cutting efficiency of the packaging tape.

[0110] In one embodiment, if Figure 6 and Figure 7 As shown, the cutting assembly 423 further includes a detection portion 4237 , and the detection portion 4237 is provided with a movable elastic pin, one end of which extends into the cutting groove 2322 .

[0111] In this embodiment, the detection portion 4237 is disposed on a side of the second housing that faces away from the second guide surface. The detection portion 4237 is provided with a movable spring pin that extends through the second housing, extends into the cutting groove 2322, and is movable relative to the second housing. It is understood that when the packaging strap enters the cutting groove 2322, it squeezes the movable spring pin. The detection portion 4237 transmits a squeezing signal of the movable spring pin to an external detection control device (not shown). The detection control device is connected to a third cylinder, which in turn controls the third cylinder to drive the movement of the third connecting member, thereby driving the pressure block to press the packaging strap against the bottom wall of the cutting groove 2322 and driving the cutting blade to cut the packaging strap.

[0112] In one embodiment, the tape cutting mechanism 2 also includes a crushing guide device 24, which includes a collecting cylinder 241 and a guide portion 243, wherein the collecting cylinder 241 is arranged on the support frame 21, and the collecting cylinder 241 forms a collecting channel 242, and the collecting channel 242 is connected to the cutting space 211. The guide portion 243 includes an active guide component 244 and a driven guide component 245. The active guide component 244 is arranged on the support frame 21 and is located at one end of the collecting channel 242 adjacent to the cutting space 211. The driven guide component 245 is movably arranged on the support frame 21 and can move toward the active guide component 244 to clamp the packaging tape. The driven guide component 245 cooperates with the active guide component 244 to transfer the packaging tape to the collecting channel 242.

[0113] In this embodiment, if Figures 1 to 4 、 Figure 8 As shown, the collecting barrel 241 is provided with a recovery port connected to the collecting channel 242, and the recovery port faces the cutter assembly 232. The collecting barrel 241 is configured to be wide at the top and narrow at the bottom. The recovery port is located at the upper end of the collecting barrel 241, and the lower end of the collecting barrel 241 can be connected to a crushing device.

[0114] It can be understood that after the detection control device detects that the package to be unpacked wrapped with the packaging tape moves to the cutting space 211, it controls the second cylinder to drive the top corner pressure plate 2317 to press against the top corner of the edge to fix the position of the package to be unpacked, and then controls the first cylinder to drive the frame pressure plate 2313 to move, and presses the opposite sides of the packaging tape against the edge through the first protrusion 2314, so that the middle section of the packaging tape is tightened and suspended in the middle part, and then controls the shell 2321 to move along the first connecting piece 2312 until the packaging tape enters the cutting groove 2322, and controls the third cylinder to drive the pressure block to unpack the package The packaging tape is pressed against the bottom wall of the cutting groove 2322, and under the further driving action of the third cylinder, the cutting knife cuts off the packaging tape, controls the first cylinder to drive the first connecting member 2312 to move, and controls the shell 2321 to move toward the recovery port. When the shell 2321 moves to the recovery port, controls the third cylinder to drive the pressing block to move to loosen the cut packaging tape. At this time, the active guide component 244 and the driven guide component 245 of the guide part 243 cooperate to bring the packaging tape from the recovery port into the collection channel 242, and then falls into the crushing device under the action of gravity for crushing.

[0115] In this embodiment, if Figure 8 As shown, the active guide assembly 244 is provided with an active roller, and the passive guide assembly 245 is provided with a passive roller. The passive roller and the active roller rotate in conjunction to clamp the packaging tape and convey it to the collection channel 242. It can be understood that the active guide assembly 244 includes a first mounting frame and a motor. The first mounting frame is connected to the collection drum 241 and is located at the opening of the collection channel 242. The active roller is rotatably mounted on the first mounting frame, and the motor is connected to one end of the active roller.

[0120] In this embodiment, if Figure 1 and Figure 2 As shown, the mounting frame 31 is used to mount, secure, and support components such as the drive assembly 32 and the gripping assembly 33. The mounting frame 31 is also provided on the housing 1. Of course, the mounting frame 31 can also be provided separately from the housing 1. As can be understood, the mounting frame 31 is provided adjacent to the conveying channel 11 and has a cover opening space 311 corresponding to the cover opening station.

[0121] It is understandable that the driving assembly 32 can be a driving cylinder, a driving module or other structure that can drive the clamping assembly 33 to move and provide driving force, and is not limited here. In this embodiment, the mounting frame 31 is provided with a movable track, which extends from the cover opening space 311 to the recycling space 312. In this way, the driving assembly 32 can be used to drive the clamping assembly 33 in the cover opening space 311 to clamp the upper cover of the package to be unpacked at the cover opening station in the clamping groove of the clamping assembly 33. Then, the clamping assembly 33 is driven to drive the upper cover to move along the movable track to the recycling space 312, and the upper cover in the clamping groove is placed in the recycling space 312 to achieve recycling of the upper cover.

[0122] In this embodiment, the clamping assembly 33 can be a clamping cylinder, a cylinder combined with a clamping plate structure, or a clamping claw structure, etc., which is not limited here.

[0123] In one embodiment, the film cutting mechanism 4 includes a distance measuring component 41 and a cutting structure 42, wherein the distance measuring component 41 includes a bracket 411, a driving cylinder 412 and a distance measuring sensor 413. The bracket 411 is arranged adjacent to the conveying channel 11, and the driving cylinder 412 is arranged on the bracket 411, and the telescopic rod of the driving cylinder 412 is connected to the distance measuring sensor 413. The distance measuring sensor 413 is arranged opposite to the film cutting station.

The cutting structure 42 is arranged adjacent to the conveying channel 11 and is located on the side of the conveying channel 11 away from the bracket 411. The cutting structure 42 is used to cut the outer film of the film cutting station.

[0124] In this embodiment, when the conveying channel 11 on the body 1 conveys the package to be unpacked with the upper cover removed to the film cutting station, the distance measuring sensor 413 of the distance measuring component 41 detects the position of the outer film on the package to be unpacked, and the distance measuring sensor 413 transmits an electrical signal to the cutting structure 42. The cutting structure 42 moves to the position of the outer film according to the electrical signal, and then allows the cutting structure 42 to accurately cut the outer film between two adjacent cylindrical products, thereby improving the disassembly and assembly effect of the unpacking equipment 100.

[0125] Understandably, Figure 1 、 Figure 2 、 Figures 9 to 12 As shown, bracket 411 includes a bottom frame and a top frame, which are connected to the bottom frame to form an integral structure. The top frame has an L-shaped or T-shaped longitudinal cross-section, and the transverse rod of the top frame is connected to the distance sensor 413, which facilitates the installation and assembly of the distance sensor 413 on bracket 411.

Optionally, the driving cylinder 412 can be a cylinder structure.

[0127] In one embodiment, the cutting structure 42 includes a fixed frame 421, a manipulator 422 and a cutting assembly 423, wherein the fixed frame 421 is arranged adjacent to the conveying channel 11 and is located on the side of the conveying channel 11 away from the bracket 411, the manipulator 422 is arranged on the fixed frame 421, and the cutting assembly 423 includes a mounting plate 4231, a cutting knife 4232 and a detection sensor 4236, the mounting plate 4231 is connected to the end of the manipulator 422 away from the fixed frame 421, the cutting knife 4232 is arranged on the side of the mounting plate 4231 facing away from the manipulator 422, the detection sensor 4236 is arranged on the side of the mounting plate 4231 facing away from the manipulator 422, and is spaced apart from the cutting knife 4232, and the detection sensor 4236 is used to detect the position of the package to be unpacked.

[0128] In this embodiment, if Figure 9 and Figure 12 As shown, the cutting structure 42 also includes an electrical control box, which is electrically connected to the manipulator 422. After the manipulator 422 receives the electrical signal transmitted by the ranging sensor 413, it immediately drives the cutting component 423 to move, thereby enabling the cutting structure 42 to cut the outer film outside the cylindrical product to be unpacked.

[0129] Optionally, the manipulator 422 is a six-axis manipulator, so that the manipulator 422 can drive the cutting assembly 423 to move more flexibly, thereby improving the cutting effect of the cutting structure 42. In this embodiment, the mounting plate 4231 is detachably connected to the manipulator 422 via a connector, so that the cutting blade 4232 connected to the mounting plate 4231 can also be easily replaced, thereby facilitating the maintenance and replacement of the cutting assembly 423.

[0130] It can be understood that the detection sensor 4236 set on the mounting plate 4231 can detect the position of the tubular product, further improving the control accuracy of the manipulator 422, thereby improving the cutting effect of the cutting assembly 423.

[0131] In one embodiment, if Figure 12 As shown, the cutting structure 42 also includes a film clamping assembly 4237 arranged on the mounting plate 4231. The film clamping assembly 4237 and the cutting knife 4232 are spaced apart, and the film clamping assembly 4237 is used to clamp the outer film after cutting; wherein, after the cutting knife 4232 cuts the outer film, the film clamping assembly 4237 clamps the outer film after cutting.

[0132] As can be understood, when the outer packaging to be removed, with the top cover removed, is transported to the film cutting station, the controller or electrical control box controls the cutting blade 4232 to cut the outer film wrapped around the multiple products. When multiple cylindrical products are wrapped in outer film, there is a cutting space between two adjacent cylindrical products. After the detection sensor 4236 detects this cutting space, the cutting blade 4232 cuts the outer film. The film clamping assembly 4237 then clamps the cut outer film, preventing it from sticking to the product surface again. This allows the cutting assembly 423 to simultaneously perform the cutting and unloading functions, thereby making the cutting assembly 423 multifunctional.

[0133] In one embodiment, if Figure 12 As shown, the film clamping assembly 4237 includes a driving cylinder and a splint, one end of the driving cylinder is rotatably connected to the mounting plate 4231, and is spaced apart from the cutting knife 4232; one side of the splint is hinged to the mounting plate 4231, and the side of the splint away from the mounting plate 4231 is rotatably connected to the telescopic rod of the driving cylinder; wherein, the driving cylinder drives the side of the splint away from the mounting plate 4231 to approach the mounting plate 4231, so that the splint and the mounting plate 4231 are close to each other and clamp the cut outer film.

[0134] In this embodiment, the telescopic rod of the driving cylinder is extended, and the telescopic rod of the driving cylinder drives the splint close to the mounting plate 4231, so that the splint and the mounting plate 4231 clamp the cut outer film; when the telescopic rod of the driving cylinder is retracted, the telescopic rod of the driving cylinder drives the splint away from the mounting plate 4231, so that the splint and the mounting package release the outer film, and then the outer film can be transferred to the appropriate position for unloading, thereby allowing the film clamping assembly 4237 to realize automatic film clamping and unloading, further improving the movement flexibility of the film clamping assembly 4237.

[0135] Alternatively, as Figure 12 As shown, a first rotating shaft is provided on one side of the mounting plate 4231, and the first rotating shaft is rotatably connected to the clamping plate. A first mounting bracket is provided on the side of the clamping plate away from the mounting plate 4231, and the first mounting bracket is provided with a first through-hole, and the telescopic rod of the driving cylinder is provided with a second through-hole. The clamping membrane assembly 4237 also includes a second rotating shaft, and the second through-hole and the second through-hole are sequentially provided on the second rotating shaft to achieve a rotatable connection between the clamping plate and the telescopic rod of the driving cylinder. A third through-hole is provided on the end of the driving cylinder away from the telescopic rod, and a second mounting bracket is provided on the mounting plate 4231, and the second mounting bracket is provided with a fourth through-hole. The clamping membrane assembly 4237 also includes a third rotating shaft, and the third through-hole and the fourth through-hole are sequentially provided on the third rotating shaft to achieve a rotatable connection between the driving cylinder and the mounting plate 4231.

[0136] In one embodiment, the splint includes a connecting plate and a clamping plate. One side of the connecting plate is hinged to the mounting plate 4231, and the side of the connecting plate away from the mounting plate 4231 is hinged to the telescopic rod of the driving cylinder. The clamping plate is connected to the side of the connecting plate away from the mounting plate 4231, and the area of ​​the clamping plate is larger than that of the connecting plate. It is understood that by dividing the splint into a connecting plate and a clamping plate, and setting the area of ​​the clamping plate larger than that of the connecting plate, this arrangement increases the contact area between the outer membrane and the clamping plate, thereby improving the membrane clamping stability of the splint.

[0137] Optionally, an elastic layer is provided on the side of the clamping plate facing the mounting plate 4231. The elastic layer can be made of silicone or rubber. With this configuration, when the elastic layer abuts the mounting plate 4231, the elastic layer deforms and comes into closer contact with the outer membrane, thereby improving the stability of the clamping plate.

[0138] In one embodiment, if Figure 12 As shown, mounting plate 4231 comprises a main plate and a baffle. The main plate is connected to the clamping plate and the drive cylinder, with the clamping plate and the drive cylinder spaced apart. The baffle is connected to the main plate, and its shape matches that of the clamping plate. By separating mounting plate 4231 into the main plate and baffle, and aligning the baffle and clamping plate in shape, when the connecting plate drives the clamping plate toward the baffle of mounting plate 4231, the baffle and clamping plate are completely aligned, thereby improving the clamping stability of the clamping plate.

[0139] In one embodiment, the cutting blade 4232 includes an ultrasonic generator 4233, an ultrasonic horn 4234, and a cutting blade 4235. The ultrasonic generator 4233 is disposed on a side of the mounting plate 4231 facing away from the manipulator 422. The ultrasonic horn 4234 is connected to the ultrasonic generator 4233. The cutting blade 4235 is connected to the ultrasonic horn 4234. The ultrasonic generator 4233 drives the ultrasonic horn 4234 to vibrate the cutting blade 4235, so that the cutting blade 4235 cuts the outer membrane.

[0140] In this embodiment, if Figure 12 As shown, when the cutting knife 4232 is in use, the ultrasonic generator 4233 is energized to drive the ultrasonic horn 4234 to vibrate, and the ultrasonic horn 4234 drives the cutter 4235 to vibrate at high speed, so that the surface of the cutter 4235 is heated, and the cutter 4235 is driven by the manipulator 422 to move and contact the outer membrane, so that the cutter 4235 can cut the outer membrane with heat, thereby making the cutting knife 4232 easier and faster to cut, thereby improving the cutting effect of the cutting assembly 423.

[0141] In one embodiment, the film cutting mechanism 4 further includes an illumination lamp, which is movably connected to the bracket 411 and spaced apart from the distance sensor 413. It will be appreciated that when the distance sensor 413 detects the position of the outer film of the tubular product, the illumination lamp illuminates and provides a detection light source for the distance sensor 413, making the detection by the distance sensor 413 more accurate, thereby improving the accuracy of the distance measurement by the distance sensor 413.

[0142] In one embodiment, the film cutting mechanism 4 also includes a waste film recovery component 43, which includes a fixed seat 431, at least one first transmission wheel 432 and at least one second transmission wheel 433, wherein the fixed seat 431 is arranged adjacent to the conveying channel 11 and is located on the side of the conveying channel 11 adjacent to the cutting structure 42, the first transmission wheel 432 is rotatably connected to the fixed seat 431, the second transmission wheel 433 is movably connected to the fixed seat 431, and is arranged opposite to the first transmission wheel 432, the second transmission wheel 433 cooperates with the first transmission wheel 432 to form a transmission gap 434, and the transmission gap 434 is used to recover the outer film after cutting.

[0143] In this embodiment, after the cutting structure 42 cuts the outer film wrapped around multiple cylindrical products, the outer film will be driven by the robot 422 to the position of the waste film recovery component 43, so that the waste film recovery component 43 will recover the discarded outer film to a suitable position, thereby avoiding the discarded outer film blocking the transmission of other cylindrical products, so as to ensure the normal operation of the unpacking equipment 100.

[0144] Understandably, Figure 1 、 Figure 2 、 Figure 9 and Figure 11 As shown, the waste film recovery component 43 also includes a first motor and a second motor. The first motor is connected to the first transmission wheel 432, and the second motor is connected to the second transmission wheel 433. The first motor drives the first transmission wheel 432 to rotate, and the second motor drives the second transmission wheel 433 to rotate, so that the first transmission wheel 432 and the second transmission wheel 433 drive the cut outer film to move to a suitable position, thereby realizing automatic recovery of waste film, thereby ensuring the normal operation of the unpacking equipment 100.

[0145] In one embodiment, if Figure 1 、 Figure 2 and Figure 9 As shown, the body 1 includes a conveyor and a positioning member, the conveyor forms a conveying channel 11, and the bracket 411 and the cutting structure 42 are respectively located on both sides of the conveyor; the positioning member is movably connected to the conveyor and is arranged adjacent to the bracket 411; wherein, when the conveyor transmits the cylindrical product to be opposite to the distance measuring sensor 413, the positioning member rises to abut against the cylindrical product.

[0146] In this embodiment, the conveyor has the advantage of being directional-variable, so that the conveyor can flexibly change the conveying direction, making it easier for the conveyor to transport multiple tubular products.

[0147] When the conveyor transmits the cylindrical products, the positioning member can rise and abut against the cylindrical products, so that the multiple cylindrical products are positioned by the positioning member, and thus the multiple cylindrical products are not easily continued to be transmitted, thereby facilitating the cutting structure 42 to cut the outer film wrapped around the multiple cylindrical products, thereby improving the cutting effect of the cutting structure 42.

[0148] It can be understood that the positioning member includes a driving cylinder and a positioning plate, the driving cylinder is arranged on the conveyor; the positioning plate is connected to the telescopic rod of the driving cylinder so that the driving cylinder drives the positioning plate to rise and fall.

[0149] In this embodiment, when the conveyor is about to move the tubular product to the bottom of the cutting structure 42, the telescopic rod of the driving cylinder is extended, and the telescopic rod of the driving cylinder drives the positioning plate to rise, so that the positioning plate rises to the top of the conveyor in advance, so that the positioning plate can contact the loading frame loaded with tubular products, thereby realizing that the positioning plate limits multiple tubular products.
