Description

Technical Field

[0001] The present invention relates to a packaging machine, and more particularly to a double-layer roll film packaging machine. Background Art

[0002] A packaging machine is a mechanical device used to wrap products in packaging materials for protection, storage or transportation. They are widely used in many industries such as food, beverage, medicine, cosmetics, and chemical industry.

[0003] During the packaging process of the packaging machine, it is necessary to first pull out the roll film in the roll film tray. During this process, labeling and punching operations need to be performed on the roll film, and then cutting is carried out. Then, the lower side of the roll film is sealed, and then the material is poured from the upper side. Finally, the lower side is sealed and unloaded. At present, it is difficult to automate the entire process, and some steps require manual participation, resulting in low work efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a double-layer roll film packaging machine.

[0005] To achieve the above object, the present invention provides the following technical solutions: It includes a frame and a feeding device, a translation device, a clamping device, and a feeding device arranged on the frame. The feeding device: feeds, divides the roll film and seals the lower side; the translation device: translates the roll film with the lower side sealed to the clamping device; the clamping device: clamps and opens the roll film; the feeding device: pours the material into the roll film device and seals the upper end of the roll film. The clamping device includes a clamping seat, a transverse movement track, a transverse movement block, a linkage block, a linkage rod, a transverse movement cylinder, a longitudinal rod, and clamping jaws. The transverse movement track is arranged on the clamping seat, two transverse movement blocks are slidably arranged on the transverse movement track, the linkage block is arranged on the transverse movement track and is located between the transverse movement blocks. One end of the linkage rod is hinged to the transverse movement block, and the other end is hinged to the linkage block. The transverse movement cylinder is arranged on the clamping seat and constitutes the same-direction or opposite-direction movement of the transverse movement blocks. The longitudinal rod is arranged on the transverse movement block, the clamping jaws are arranged on the longitudinal rod, and the clamping jaws have a clamping position for clamping the roll film. The suction head is opposite to the clamping position and sucks the side part of the roll film located at the clamping position. The transverse movement cylinder can be composed of multiple cylinders, so that the distance between the clamping jaws is continuously adjusted.

[0006] By adopting the above technical solution, before feeding is required, the feeding device pulls out the winding film from the winding film reel, cuts and seals it, then the translation device transfers the winding film to a position opposite to the clamping device, and then the clamping jaws clamp the winding film. At this time, the winding film is flat. Then, the transverse movement cylinder drives a transverse movement block to move, and then through the linkage rod and the linkage block, drives another transverse movement block to move. At this time, the two clamping jaws move towards each other, the two sides of the winding film approach, and the winding film shows corrugations. Then, the film suction heads on both sides approach the winding film, respectively suck the two sides of the winding film, and then move away from the winding film. At this time, the winding film is opened, and then the feeding device adds materials and performs subsequent sealing. By changing the distance between the clamping jaws, the space for the winding film to be opened is provided, ensuring the complete opening of the winding film. And the whole process is automated, with low manual participation and high work efficiency.

[0007] The present invention is further configured as: the clamping jaws include a clamping cylinder, a constant block and a clamping block. The constant block is fixed on the longitudinal rod, the clamping cylinder is arranged on the longitudinal rod and drives the clamping block to move longitudinally, and the constant block and the clamping block constitute the clamping of the winding film.

[0008] By adopting the above technical solution, when clamping is required, the clamping cylinder drives the clamping block to approach the constant block. At this time, the winding film is located on one side of the constant block until the clamping block abuts against the constant block to complete the clamping of the winding film.

[0009] The present invention is further configured as: it further includes a feeder, an integral cylinder, a fixing plate, a sealing plate and a sealing cylinder. The feeder is arranged on the frame and has a material clamping port opposite to the clamping position. The fixing plate is arranged on the frame and is opposite to the clamping position. The sealing cylinder is arranged on the frame and drives the sealing plate to move along the horizontal plane close to and away from the fixing plate. A top heating wire is arranged inside the sealing plate. The integral cylinder drives the clamping seat to move vertically. The feeder is a conventional technical means and will not be described in detail.

[0010] By adopting the above technical solution, when the winding film is opened, the feeder can pour the material into the winding film. After the feeding is completed, the integral cylinder drives the clamping seat to move upward until the end of the winding film moves to a position opposite to the top heating wire. Then, the sealing cylinder drives the sealing plate to move until the sealing plate abuts against the fixing plate. At this time, the top heating wire seals the winding film.

[0011] The present invention is further configured as: it further includes a support seat, a lifting mechanism, a lifting plate, an adjusting rod, an adjusting block, an adjusting cylinder and a support hopper. The support seat is arranged inside the frame and is located below the clamping position. The lifting mechanism is arranged on the support seat and drives the lifting plate to move vertically. The adjusting rod is arranged on the lifting plate. The adjusting block is rotatably arranged on the lifting plate. The adjusting cylinder drives the adjusting block to rotate. The support hopper is arranged on the adjusting block and has a support position opposite to the clamping position.

[0012] By adopting the above technical solution, when adding materials, the bottom of the winding film faces the support hopper. At this time, the support hopper is in the support position. Then, after the feeding is completed, the adjusting block can be rotated by adjusting the cylinder drive, so that the angle of the support hopper changes, facilitating discharging. The lifting mechanism is used to adjust the angle of the lifting plate to adapt to different materials.

[0013] The present invention is further configured as: including a loading rack and a driven shaft, a first high shaft, an adjusting shaft, a second high shaft, a third high shaft, a first middle shaft, a first low shaft, a second low shaft, a matching shaft, a driving shaft, a labeling platform, a labeling machine, a punching machine, and a driving motor arranged on the loading rack. The driven shaft has a placement portion for placing the winding film disk and is at a height lower than the first high shaft. The first high shaft, the second high shaft, and the third high shaft are arranged in sequence and at the same height. The adjusting shaft is located between the first high shaft and the second high shaft. The labeling platform is located between the second high shaft and the third high shaft. The labeling machine is located above the labeling platform. The first middle shaft is located between the second high shaft and the third high shaft and is at a height lower than the second high shaft. The first low shaft is directly below the first middle shaft. The second low shaft is at the same height as the first low shaft. The punching machine is located between the first low shaft and the second low shaft. The matching shaft and the driving shaft are at a height lower than the first low shaft, and there is a driving gap for the winding film to pass through between the matching shaft and the driving shaft. The driving motor drives the driving shaft to rotate, causing the winding film to move in the driving gap.

[0014] By adopting the above technical solution, when it is necessary to load the winding film, first place the winding film disk on the placement portion of the driven shaft. Driven by the driving motor, the driving shaft rotates. At this time, the winding film passes through the first high shaft, the adjusting shaft, the second high shaft, the third high shaft, the first middle shaft, the first low shaft, the second low shaft, and the driving gap in sequence. During this process, when the winding film is between the second high shaft and the third high shaft, at this time the winding film is located at the labeling platform, and then the labeling machine labels the winding film. Then, when it moves to the first low shaft and the second low shaft, the punching machine punches the winding film at this time. Then the winding film passes through the driving gap, completing the labeling and punching actions before cutting.

[0015] The present invention is further configured as: further including a fixed block, a moving block, a moving cylinder, a blade, and a cutting cylinder. The fixed block is located below the driving shaft. The fixed block is provided with a fixed groove. The moving cylinder is arranged on the loading rack and drives the moving block to move in a plane direction close to and away from the moving block. The moving block has a moving groove opposite to the fixed groove. The blade is slidably arranged in the moving groove and is driven by the cutting cylinder.

[0016] By adopting the above technical solution, when cutting is required, the moving cylinder drives the moving block to approach the fixed block. Then, driven by the cutting cylinder, the blade extends out of the moving groove and enters the fixed groove. During this process, the winding film located between the fixed block and the moving block is cut.

[0017] The present invention is further configured as: further comprising a bottom heating wire, which is arranged on the fixed block and above the fixed groove.

[0018] By adopting the above technical solution, when the moving block fits with the fixed block, the bottom heating wire will fit with the rolled film, thereby sealing the lower side of the rolled film.

[0019] The present invention is further configured as: the translation device further comprises a translation mechanism, a translation rod and translation jaws. The translation mechanism is arranged in the loading rack and drives the translation rod to move along the moving direction of the moving block. The translation jaws are arranged on the translation rod and have a clamping position located between the moving block and the fixed block.

[0020] By adopting the above technical solution, before cutting, the translation mechanism drives the translation rod to move, so that the translation jaws move to the clamping position opposite to the rolled film to clamp the rolled film, and then cutting is performed. After cutting, the cut rolled film is moved to other devices for adding materials and sealing the remaining side.

[0021] The present invention is further configured as: the translation mechanism comprises a translation motor, a translation screw, a translation track and a translation seat. The translation track is arranged along the moving direction of the moving block.

One end of the linkage rod 214 is hinged to the transverse movement block 212, and the other end is hinged to the linkage block 213. The transverse movement cylinder 215 is arranged on the clamping seat 21 and constitutes the same-direction or opposite-direction movement of the transverse movement block 212. The longitudinal rod 216 is arranged on the transverse movement block 212, the clamping jaw 217 is arranged on the longitudinal rod 216 and the clamping jaw 217 has a clamping position for clamping the coiled film. The film suction head 218 is opposite to the clamping position and sucks the side part of the coiled film located at the clamping position. Before feeding, the feeding device 1 pulls out the coiled film from the coiled film reel, cuts and seals it, then the translation device 10 transfers the coiled film to a position opposite to the clamping device 2, and then the clamping jaw 217 clamps the coiled film. At this time, the coiled film is flat. Then the transverse movement cylinder 215 drives one transverse movement block 212 to move, and then through the linkage rod 214 and the linkage block 213, drives the other transverse movement block 212 to move. At this time, the two clamping jaws 217 move towards each other, the two sides of the coiled film approach, and the coiled film shows corrugations. Then the film suction head 218 approaches the coiled film, sucks one side of the coiled film, and then moves away from the coiled film. At this time, the coiled film is opened, which is convenient for subsequent feeding. By changing the distance between the clamping jaws 217, the space for opening the coiled film is provided, ensuring the complete opening of the coiled film.

[0034] The clamping jaw 217 includes a clamping cylinder 2171, a constant block 2172 and a clamping block 2173. The constant block 2172 is fixed on the longitudinal rod 216. The clamping cylinder 2171 is arranged on the longitudinal rod 216 and drives the clamping block 2173 to move longitudinally. The constant block 2172 and the clamping block 2173 constitute the clamping of the coiled film. When clamping is required, the clamping cylinder 2171 drives the clamping block 2173 to approach the constant block 2172 through driving. At this time, the coiled film is located on one side of the constant block 2172 until the clamping block 2173 abuts against the constant block 2172, completing the clamping of the coiled film.

[0035] The feeding device 20 further includes a feeder 23, an integral cylinder 24, a fixing plate 241, a sealing plate 242 and a sealing cylinder 243.

The fixing plate 241 is arranged on the frame 22 and opposite to the clamping position. The sealing cylinder 243 is arranged on the frame 22 and drives the sealing plate 242 to move along a horizontal plane close to and away from the fixing plate 241. A top heating wire 244 is arranged inside the sealing plate 242. The integral cylinder 24 drives the clamping seat 21 to move vertically. When the roll film is opened, the feeder 23 can pour the material into the roll film. After the feeding is completed, the integral cylinder 24 drives the clamping seat 21 to move upward until the end of the roll film moves to a position opposite to the top heating wire 244. Then the sealing cylinder 243 drives the sealing plate 242 to move until the sealing plate 242 abuts against the fixing plate 241. At this time, the top heating wire 244 seals the roll film.

[0036] It further includes a support seat 25, a lifting mechanism 251, a lifting plate 252, an adjusting rod 253, an adjusting block 254, an adjusting cylinder 255 and a support hopper 256. The support seat 25 is arranged inside the frame 22 and below the clamping position. The lifting mechanism 251 is arranged on the support seat 25 and drives the lifting plate 252 to move vertically. The adjusting rod 253 is arranged on the lifting plate 252. The adjusting block 254 is rotatably arranged on the lifting plate 252. The adjusting cylinder 255 drives the adjusting block 254 to rotate. The support hopper 256 is arranged on the adjusting block 254 and has a support position opposite to the clamping position. When adding materials, the bottom of the roll film is opposite to the support hopper 256. At this time, the support hopper 256 is in the support position. Then after the feeding is completed, the adjusting cylinder 255 can be used to drive the adjusting block 254 to rotate, so that the angle of the support hopper 256 changes, thereby facilitating discharging. The lifting mechanism 251 is used to adjust the angle of the lifting plate 252 to adapt to different materials.

[0037] The feeding device 1 includes a feeding rack 11, a driven shaft 12, a first high shaft 121, an adjustment shaft 122, a second high shaft 123, a third high shaft 124, a first middle shaft 125, a first low shaft 126, a second low shaft 127, a matching shaft 128, a driving shaft 129, a labeling platform 13, a labeling machine 131, a punching machine 132, and a driving motor 1291 arranged on the feeding rack 11. The driven shaft 12 has a placement part for placing a roll film disk and is at a height lower than the first high shaft 121. The first high shaft 121, the second high shaft 123, and the third high shaft 124 are arranged in sequence and at the same height. The adjustment shaft 122 is located between the first high shaft 121 and the second high shaft 123. The labeling platform 13 is located between the second high shaft 123 and the third high shaft 124. The labeling machine 131 is located above the labeling platform 13. The first middle shaft 125 is located between the second high shaft 123 and the third high shaft 124 and is at a height lower than the second high shaft 123. The first low shaft 126 is directly below the first middle shaft 125. The second low shaft 127 is at the same height as the first low shaft 126. The punching machine 132 is located between the first low shaft 126 and the second low shaft 127. The matching shaft 128 and the driving shaft 129 are at a height lower than the first low shaft 126, and there is a driving gap for the roll film to pass through between the matching shaft 128 and the driving shaft 129. The driving motor 1291 drives the driving shaft 129 to rotate, causing the roll film to move in the driving gap. When feeding the roll film, first place the roll film disk on the placement part of the driven shaft 12. Driven by the driving motor 1291, the driving shaft 129 rotates. At this time, the roll film passes through the first high shaft 121, the adjustment shaft 122, the second high shaft 123, the third high shaft 124, the first middle shaft 125, the first low shaft 126, the second low shaft 127, and the driving gap in sequence. During this process, when the roll film is between the second high shaft 123 and the third high shaft 124, the roll film is at the labeling platform 13. Then the labeling machine 131 labels the roll film. Then when it moves to the first low shaft 126 and the second low shaft 127, the punching machine 132 punches the roll film at this time. Then the roll film passes through the driving gap, completing the labeling and punching actions before cutting.

[0038] It further includes a fixed block 14, a moving block 15, a moving cylinder 151, a blade 152, and a cutting cylinder 153. The fixed block 14 is located below the driving shaft 129. The fixed block 14 is provided with a fixed groove 154. The moving cylinder 151 is arranged on the feeding rack 11 and drives the moving block 15 to move in a plane direction close to and away from the moving block 15. The moving block 15 has a moving groove 141 opposite to the fixed groove 154. The blade 152 is slidably arranged in the moving groove 141 and is driven by the cutting cylinder 153. When cutting is required, the moving cylinder 151 drives the moving block 15 to approach the fixed block 14. Then the blade 152, driven by the cutting cylinder 153, extends out of the moving groove 141 and enters the fixed groove 154. During this process, the roll film located between the fixed block 14 and the moving block 15 is cut.

[0039] It further includes a bottom heating wire 142, which is arranged on the fixing block 14 and above the fixing groove 154. When the moving block 15 fits with the fixing block 14, the bottom heating wire 142 will be in contact with the rolled film, thereby sealing the lower side of the rolled film.

[0040] The translation device 10 further includes a translation mechanism 16, a translation rod 161 and a translation jaw 162. The translation mechanism 16 is arranged in the loading rack 11 and drives the translation rod 161 to move along the moving direction of the moving block 15. The translation jaw 162 is arranged on the translation rod 161 and has a clamping position between the moving block 15 and the fixing block 14. Before cutting, the translation mechanism 16 drives the translation rod 161 to move, so that the translation jaw 162 moves to the clamping position opposite to the rolled film to clamp the rolled film, and then cutting is carried out. After cutting, the cut rolled film is moved to other devices for adding materials and sealing the remaining side.

[0041] The translation mechanism 16 includes a translation motor 163, a translation screw 164, a translation track 165 and a translation seat 166. The translation track 165 is arranged along the moving direction of the moving block 15. The translation motor 163 is arranged on the loading rack 11 and drives the translation screw 164 to rotate, and the translation screw 164 is parallel to the translation track 165. The translation seat 166 is arranged on the translation screw 164 and moves along the translation track 165. The translation rod 161 is arranged on the translation seat 166.

[0042] Working process: When it is necessary to load the roll film, first place the roll film reel on the placement part of the driven shaft 12. Driven by the driving motor 1291, the driving shaft 129 rotates. At this time, the roll film passes through the first high shaft 121, the adjustment shaft 122, the second high shaft 123, the third high shaft 124, the first middle shaft 125, the first low shaft 126, the second low shaft 127 and the driving gap in sequence. During this process, when the roll film is between the second high shaft 123 and the third high shaft 124, the roll film is located at the labeling platform 13. Then, the labeling machine 131 labels the roll film. Then, when it moves to the first low shaft 126 and the second low shaft 127, the punching machine 132 punches the roll film at this time. Then, the roll film passes through the driving gap. The translation mechanism 16 drives the translation rod 161 to move, so that the translation gripper 162 moves to the clamping position opposite to the roll film and clamps the roll film. Then, the moving cylinder 151 drives the moving block 15 to approach the fixed block 14. Then, the blade 152 extends out of the moving groove 141 under the drive of the cutting cylinder 153 and enters the fixed groove 154. During this process, the roll film between the fixed block 14 and the moving block 15 is cut. At the same time, the bottom heating wire 142 will be attached to the roll film, so as to seal the lower side of the roll film. After cutting, the cut roll film is moved to the position opposite to the clamping device 2. The clamping cylinder 2171 drives the clamping block 2173 to approach the constant block 2172. At this time, the roll film is on one side of the constant block 2172 until the clamping block 2173 abuts against the constant block 2172 to complete the clamping of the roll film. At this time, the roll film is flat. Then, the transverse movement cylinder 215 drives a transverse movement block 212 to move. Then, through the linkage rod 214 and the linkage block 213, the other transverse movement block 212 is driven to move. At this time, the two clamping grippers 217 move towards each other, the two sides of the roll film approach, and the roll film shows corrugations. Then, the suction heads 218 on both sides approach the roll film, suck one side of the roll film, and then move away from the roll film. At this time, the roll film is opened, and the feeder 23 can pour the material into the roll film. During the process of adding the material, the bottom of the roll film is opposite to the support hopper 256. At this time, the support hopper 256 is in the support position. When the feeding is completed, the integral cylinder 24 drives the clamping seat 21 to move upward until the end of the roll film moves to the position opposite to the top heating wire 244. Then, the sealing cylinder 243 drives the sealing plate 242 to move until the sealing plate 242 abuts against the fixing plate 241. At this time, the top heating wire 244 seals the roll film, and finally the unloading is completed.
