DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-9 As shown, a solvent-free laminating machine for producing packaging bags of the present invention comprises a machine body 1, a control console 11 is provided on the front side of the machine body 1, fixed plates 12 are provided on the front and rear sides of the inner side of the machine body 1, a rotating shaft 13 is rotatably mounted between the two fixed plates 12, one of the fixed plates 12 is equipped with a first motor 131 which is transmission-connected to the rotating shaft 13, rotating plates 14 are provided on the left and right sides of the rotating shaft 13, the two rotating plates 14 are symmetrically provided with notches 15, two opposite notches 15 between the two rotating plates 14 are jointly equipped with winding rollers 16, one of the fixed plates 12 is equipped with a transmission mechanism matching the two winding rollers 16, and the two fixed plates 12 are mutually connected. A C-shaped ring 17 surrounding the rotating plate 14 is provided on one side, and the C-shaped ring 17 matches the notch 15 on the upper side. An arc plate 2 is installed at the notch of the two C-shaped rings 17. The arc plate 2 and the C-shaped ring 17 surround the rotating plate 14 together. The arc plate 2 matches the position of the lower notch 15. A support plate 21 is installed on the lower side of the two arc plates 2. Universal wheels 211 are installed at the four corners of the lower side of the support plate 21. The two arc plates 2 are provided with grooves 22 matching the lower notch 15. Arc support members 23 are installed in the two grooves 22 for sliding up and down. A lifting mechanism matching the two arc support members 23 is installed in the support plate 21.

[0032] When the processed packaging bag needs to be rolled up, one end of the packaging bag that has passed through the machine body 1 and has been processed can be fixed on the outer surface of the winding roller 16 located on the upper side. At this time, the transmission mechanism drives the winding roller 16 on the upper side to start rotating, so that the packaging bags that are continuously removed from the machine body 1 can be rolled up.

[0033] When the upper winding roller 16 has rolled up the packaging bag to the limit, the connection between the packaging bag removed from the machine body 1 and the upper winding roller 16 is cancelled, and the first motor 131 is started at this time to drive the rotating shaft 13 to start rotating 90 degrees. When the rotating shaft 13 rotates, the rotating plates 14 on both sides can be driven to start rotating. During the rotation of the rotating plates 14, the winding roller 16 located in the lower notch 15 and not wrapped with the packaging bag can be located on the upper side, while the winding roller 16 wrapped with the packaging bag can be located on the lower side. Then the first motor 131 stops working, and then the packaging bag is connected to the outer surface of the upper winding roller 16 again, so that the packaging bag can be quickly rolled up, saving the time of unloading and improving the work efficiency.

[0034] When the winding roller 16 with the packaging bag wrapped around it is located at the lower side, the two ends of the winding roller 16 match the positions of the grooves 22 respectively and are located on the upper side of the arc-shaped support member 23. At this time, the lifting mechanism stops working, and drives the arc-shaped support member 23 that has been measured to start moving downward, until the winding roller 16 with the packaging bag wrapped around it moves downward out of the notch 15 and is located inside the groove 22, until the arc-shaped support member 23 is located at the bottom of the groove 22, so that the two ends of the winding roller 16 with the packaging bag wrapped around it are completely located in the groove 22. Since the lower end of the support plate 21 is provided with a universal wheel 211, when the staff moves the support plate 21, the winding roller 16 with the packaging bag wrapped around it can be moved out from between the two fixed plates 12, and the arc plate 2 is separated from the rotating plate 14. Such a design can quickly and conveniently remove the winding roller 16 with the packaging bag wrapped around it from between the two rotating plates 14 without using electrical equipment. Moreover, since the winding roller 16 with the packaging bag wrapped around it has a large mass, such a design can also prevent the staff from manually carrying the winding roller 16 with the packaging bag wrapped around it, thereby reducing the workload of the staff and The staff can push the support plate 21 to move, and then the winding roller 16 with the packaging bag wrapped around it can be moved to the next processing equipment position, and the new winding roller 16 can be placed in the two grooves 22. Since the upper end of the arc-shaped support member 23 is an arc surface, when the two ends of the new winding roller 16 are located in the groove 22, they can be accurately located on the upper surface of the two arc-shaped support members 23. At this time, the staff can push the support plate 21 to re-enter between the two fixed plates 12 to ensure that the arc plates 2 on both sides are in contact with the rotating plate 14 again, and the arc plates 2 and the C-shaped ring 1 7 cooperates to completely wrap the rotating plate 14, and then starts the lifting mechanism, driving the arc-shaped support members 23 in the grooves 22 on both sides to start moving upward, and the arc-shaped support members 23 on both sides drive the winding roller 16 to move upward. Since the upper surface of the arc-shaped support member 23 is arc-shaped, the winding roller 16 will not be displaced on the upper surface of the arc-shaped support member 23, and will be accurately moved into the notch 15 on the lower side under the action of the arc-shaped support member 23, so as to provide the next replacement of the winding roller 16. The overall design of the equipment can effectively improve the processing efficiency of packaging bags.

[0035] The transmission mechanism includes a second motor 3 mounted on a fixed plate 12. The second motor 3 is equipped with a rotating member 31 passing through the fixed plate 12. The rotating member 31 matches the position of the notch 15 on the upper side. A rectangular hole 32 is provided in the rotating member 31. A first spring 33 is provided in the rectangular hole 32. A slider 34 is provided on the side of the first spring 33 away from the second motor 3. A pulling component matching the slider 34 is provided in the rectangular hole 32. The slider 34 is equipped with a rectangular transmission rod 35 that can extend out of the rectangular hole 32. Transmission holes 36 matching the rectangular transmission rod 35 are provided on the end faces of the two winding rollers 16.

[0036] When the winding roller 16 is located on the upper side and the transmission hole 36 matches the position of the rotating member 31, the pulling component stops working. Under the action of the extension of the first spring 33, the slider 34 can be pushed to move, driving the rectangular transmission rod 35 to move out of the rectangular hole 32 until the rectangular transmission rod 35 contacts the rectangular hole 32. When the second motor 3 starts to work, it drives the rotating member 31 to start rotating. The rotating member 31 drives the rectangular transmission rod 35 to start rotating until the rectangular transmission rod 35 matches the transmission hole 36. The rectangular transmission rod 35 will extend into the transmission hole 36 under the action of the extension of the first spring 33. Therefore, when the rectangular transmission rod 35 rotates, it can drive the winding roller 16 to start rotating. When it is necessary to cancel the connection between the rotating member 31 and the winding roller 16, the pulling component starts working, pulling the slider 34 into the rectangular hole 32, and the first spring 33 is compressed, thereby driving the rectangular transmission rod 35 to move out of the transmission hole 36. At this time, the rotating member 31 cancels the connection with the winding roller 16.

[0037] The pulling assembly includes an electromagnet 37 disposed on the inner wall of the rectangular hole 32, and the slider 34 is an iron slider. When the electromagnet 37 is powered, the electromagnet 37 can adsorb the slider 34, drive the slider 34 to move to one side of the electromagnet 37, and drive the first spring 33 to compress. When the electromagnet 37 is powered off, the slider 34 can be reset under the action of the first spring 33 being stretched.

[0038] The rectangular transmission rod 35 has a conical end surface, which can facilitate the rectangular transmission rod 35 to extend into the transmission hole 36.

[0039] The lifting mechanism includes a cavity 4 arranged in the support plate 21, a slide plate 41 is slidingly and sealably assembled in the cavity 4, a stabilizing rod 42 matching the support plate 21 is arranged between the two fixed plates 12, a hydraulic oil is injected into the cavity 4 on the side of the slide plate 41 away from the stabilizing rod 42, telescopic rods 43 connected to the inner wall of the cavity 4 are arranged on the left and right sides of the slide plate 41 away from the stabilizing rod 42, and the outer surfaces of the two telescopic rods 43 are sleeved with second springs 44, a protruding port 45 is arranged on the side of the cavity 4 close to the stabilizing rod 42, and the stabilizing rod 42 is provided with a push rod 46 matching the protruding port 45, an inner cavity 47 located at the lower side of the groove 22 is arranged on the left and right sides of the support plate 21, a push block 48 is slidingly and sealably assembled in the inner cavity 47, the push block 48 is provided with a connecting rod 49 that slides into the groove 22 and is connected to the arc support member 23, and the lower inner walls of the two inner cavities 47 are provided with connecting holes 491 connected to the inner cavity 47.

[0040] When the staff needs to move the new winding roller 16 into the notch 15 on the lower side of the rotating plate 14, the two ends of the new winding roller 16 are respectively located in the two grooves 22, and the support plate 21 is moved between the two fixed plates 12. When the support plate 21 moves into the fixed plate 12, the top rod 46 on the surface of the stabilizing rod 42 passes through the protruding opening 45 to contact the slide plate 41, pushing the slide plate 41 to move in the cavity 4, driving the telescopic rods 43 and the second spring 44 on both sides to compress, and injecting hydraulic oil into the inner cavities 47 on both sides through the connecting holes 491 on both sides, thereby pushing the top block 48 to move upward, and the top block 48 pushes the arc support member 23 in the groove 22 through the connecting rod 49. By moving upward, the arc-shaped support members 23 on both sides can be driven to move upward, and the new winding roller 16 can be moved into the notch 15 on the lower side to complete the installation of the new winding roller 16. When the winding roller 16 with the packaging bag wrapped around it needs to be moved out from the notch on the lower side, the staff can directly push the support plate 21 outward to move the support plate 21 out from between the two fixed plates 12. At this time, the push rod 46 gradually cancels the contact with the slide plate 41, and then under the action of the extension of the second spring 44, the slide plate 41 is driven to reset, so that the hydraulic oil in the inner cavity 47 on both sides is sucked back into the cavity 4, which can gradually drive the top block 48 to move downward, and drive the arc-shaped support member 23 to move downward through the connecting rod 49.

[0041] The gap 15 is provided with an arc-shaped baffle 5 which matches the winding roller 16. The design of the arc-shaped baffle 5 can ensure that the winding roller 16 will not slide left and right in the two gaps 15.

[0042] The support plate 21 is provided with an armrest 51. The design of the armrest 51 can facilitate the staff to push the support plate 21.

[0043] The two fixing plates 12 are provided with threaded holes 52 on both sides, and the support plate 21 is provided with limit blocks 53 on both sides. The two limit blocks 53 are both threadedly connected with threaded members 54 matching the threaded holes 52 .

[0044] When the support plate 21 is located between the two fixing plates 12 , the screw member 54 can pass through the limiting block 53 and be screwed into the threaded hole 52 to limit the support plate 21 and prevent the support plate 21 from shaking.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
