Description

Technical Field

[0001] This utility model relates to the field of waste material winding technology for blister packaging machines, and in particular to a waste material winding device for blister packaging machines. Background Technology

[0002] A vacuum forming machine is a machine that uses heated and plasticized thermoplastic plastic rolls such as PVC, PE, PP, PET, and HIPS to form various shapes of high-end packaging and decorative boxes, frames, and other products. It uses the vacuum suction generated by a vacuum pump to vacuum form various shapes of vacuum covers, blister trays, blister packs, etc., from heated and softened thermoplastic plastic sheets such as PVC and PET through molds.

[0003] Chinese Patent 202421543336.8 relates to a waste material winding device for a thermoforming machine. The winding device includes a support body and a roll for supporting the support body. The support body includes two parallel, spaced-apart support bars and a support frame for supporting the support bars. Each end of the support bar has a rotating seat for supporting the roll. A cutting groove connects the middle of the two support bars. A drive gear is located on the side wall of each support bar near one of the rotating seats, and the drive gear meshes with a driven gear on the rotating shaft of the roll. The winding device also includes a cutting component that works with the cutting groove. When cutting waste material, the cutting component presses the waste material into the cutting groove for cutting. This invention solves the technical problem that current support structures for rolls are simple and inconvenient for workers to change the roll.

[0004] After the waste material is wound up, the operator needs to first remove the roll from one of the rotating seats, then reinstall the roll onto the other rotating seat, cut the waste material, and finally reinstall the empty roll onto the rotating seat for winding again. Throughout the entire process of disassembly, installation, cutting, and reinstallation, the blister packaging machine does not stop operating, and waste material is continuously generated. Because the roll replacement process of the above-mentioned winding device is cumbersome and time-consuming, the newly generated waste material may not be effectively wound up in a timely manner during roll replacement, thus affecting the continuity of production and work efficiency. Therefore, a waste material winding device for blister packaging machines is proposed to solve the above problems. Utility Model Content

At this time, the operator only needs to switch the winding cylinder after the rotating plate switches the winding cylinder, which reduces the winding time of manually changing the winding cylinder, ensures real-time waste material processing, and improves production continuity.

[0015] Preferably, the outer surface of the winding shaft is provided with a first limiting block arranged in a ring array. The first limiting block is connected to the abutment plate and inserted into a limiting groove opened inside the inner wall of the winding drum near the rotating plate.

[0016] Preferably, the limiting member includes a threaded ring and a first annular plate, the first annular plate being fixedly sleeved on the outer surface of the threaded ring, the outer surface of the drum mounting shaft being provided with threads, and the threaded ring being threadedly connected to the drum mounting shaft and abutting against the take-up drum.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1-6 As shown, the present invention proposes a waste material winding device for a vacuum forming machine, including a main base plate 12, a first side plate 11, a second side plate 15, a transmission shaft 2, and a second motor 17. The main base plate 12 has secondary base plates 9 on both sides. The lower end surfaces of the secondary base plates 9 and the main base plate 12 are located on the same plane. The secondary base plates 9 on both sides are connected to the first side plate 11 and the second side plate 15 through support frames 10, respectively. This structural design makes the support of the entire device more stable.

[0035] The first side plate 11 and the second side plate 15 are perpendicularly arranged at both ends of the main base plate 12 to form a stable frame structure;

[0036] The second motor 17 is installed on the outside of the second side plate 15. One end of the transmission shaft 2 is rotatably connected to the first side plate 11, and the other end passes through the second side plate 15 and is coaxially connected to the output end of the second motor 17 through a coupling.

[0037] A rotating plate 3 and a mounting plate 1 are fitted onto the drive shaft 2. The rotating plate 3 is located on the side closer to the second motor 17, and the mounting plate 1 is located on the side closer to the first side plate 11.

[0038] The rotating plate 3 is equipped with a winding mechanism at both ends for winding up the waste material of the blister packaging machine;

[0039] The mounting plate 1 has symmetrical limiting holes 4 on both sides. The edge of the first side plate 11 is provided with a limiting component that cooperates with the limiting holes 4. The limiting component cooperates with the limiting holes 4 to limit and fix the mounting plate 1. The first side plate 11 and the rotating plate 3 are arranged in parallel.

[0040] In this invention, during use, the waste material is first wound onto a winding mechanism on one side. Then, this winding mechanism is started to wind up the waste material generated by the vacuum forming machine. After the winding mechanism on one side finishes winding up the waste material, the waste material is cut, and the limiting component is activated to allow the limiting end to exit from the limiting hole 4, thus releasing the limitation on the mounting plate 1. Then, the second motor 17 is started to rotate the rotating plate 3 180°, rotating the winding mechanism that has not been wound up to the winding position. The limiting component is activated again to allow the limiting end to insert into the corresponding limiting hole 4, thus limiting and fixing the mounting plate 1. The cut waste material is then rewound onto a new winding mechanism, and the new winding mechanism is started to wind up the waste material. At this time, the operator can disassemble and replace the waste material collection end on the winding mechanism that is full of waste material, and then replace it with an empty waste material collection end for repeated operation.

[0041] In an optional embodiment, the winding mechanism includes a first motor 16, a drum mounting shaft 8, a stop plate 20, a winding drum 5, and a limiting member. The first motor 16 is mounted on the side of the rotating plate 3 near the second side plate 15, and its output shaft passes through the rotating plate 3 and is coaxially connected to the drum mounting shaft 8. The stop plate 20 is fixed to one end of the drum mounting shaft 8 near the rotating plate 3. The limiting member is detachably connected to the other end of the drum mounting shaft 8. The winding drum 5 is sleeved on the drum mounting shaft 8 and located between the stop plate 20 and the limiting member.

[0042] It should be noted that when the corresponding first motor 16 is started, the first motor 16 can drive the roll mounting shaft 8 to rotate, thereby driving the take-up drum 5 to take up the waste material generated by the vacuum forming machine.

[0043] In an optional embodiment, the outer surface of the roll mounting shaft 8 is provided with a first limiting block 19 arranged in an annular array. The first limiting block 19 is connected to the abutment plate 20 and inserted into the limiting groove 18 opened inside the inner wall of the take-up drum 5 near the rotating plate 3. The abutment plate 20 is provided with an annular sliding groove 22 on the side near the rotating plate 3. The rotating plate 3 is provided with a slider 21 arranged in an annular array at the corresponding position. One end of the slider 21 is located in the sliding groove 22. The annular array of the sliding groove 22, the abutment plate 20, the roll mounting shaft 8 and the slider 21 are arranged with the same center.

[0044] It should be noted that the first limiting block 19 cooperates with the limiting groove 18 to prevent the winding drum 5 from sliding; the abutment plate 20 and the rotating plate 3 cooperate with the slider 21 and the sliding slot 22 to ensure the stable rotation of the drum mounting shaft 8.

[0045] In an optional embodiment, the limiting member includes a threaded ring 7 and a first annular plate 6. The first annular plate 6 is fixedly sleeved on the outer surface of the threaded ring 7. The outer surface of the drum mounting shaft 8 is provided with threads. The threaded ring 7 is threadedly connected to the drum mounting shaft 8 and abuts against the take-up drum 5. The first annular plate 6 is flush with the end face of the threaded ring 7 near the rotating plate 3.

[0046] It should be noted that when the operator disassembles and replaces the winding drum 5 which is full of waste material, the threaded ring 7 is rotated to unscrew it from the drum mounting shaft 8. Then, the winding drum 5 is removed from the drum mounting shaft 8, an empty winding drum 5 is installed, and the threaded ring 7 is screwed back on to complete the replacement of the winding drum 5.

[0047] In an optional embodiment, the limiting assembly includes an electric push rod 13, a push rod mounting plate 14, and a second limiting block 23. The push rod mounting plate 14 is fixed to the outer edge of the first side plate 11. The electric push rod 13 is mounted on the side of the push rod mounting plate 14 away from the mounting plate 1, and its telescopic shaft passes through the push rod mounting plate 14 and is connected to the second limiting block 23. The second limiting block 23 is inserted into the corresponding limiting hole 4. The limiting holes 4 on both sides of the mounting plate 1 are centrally symmetrically distributed.

[0048] It should be noted that when a take-up drum 5 is full of waste material, the waste material is first cut, and the electric push rod 13 is activated. The electric push rod 13 drives the second limit block 23 to exit from the limit hole 4, releasing the limit on the mounting plate 1. Then, the second motor 17 is activated, causing the rotating plate 3 to rotate 180°, rotating the other empty take-up drum 5 to the take-up position. The electric push rod 13 is activated again, causing the second limit block 23 to insert into the corresponding limit hole 4, thereby limiting and fixing the mounting plate 1 and ensuring the stability when taking up the waste material.

[0049] In an optional embodiment, the lower end faces of the base plate 9 and the main base plate 12 are on the same plane, and the two sides of the base plate 9 are fixedly connected to the second side plate 15 and the two sides of the first side plate 11 respectively through the support frame 10.

[0050] It should be noted that the support frame 10 improves the stability of the first side plate 11 and the second side plate 15.

[0051] Working principle: When in use, first install the equipment in a suitable position, ensuring that the main base plate 12 and the secondary base plate 9 are placed stably, start the second motor 17, the second motor 17 drives the transmission shaft 2 to rotate, which in turn drives the rotating plate 3 and the mounting plate 1 to rotate.

[0052] When one of the take-up drums 5 starts to take up the waste material, the corresponding first motor 16 is started. The first motor 16 drives the drum mounting shaft 8 to rotate, thereby driving the take-up drum 5 to take up the waste material generated by the vacuum forming machine.

[0053] When a take-up drum 5 is full of waste material, the waste material is first cut, and the electric push rod 13 is activated. The electric push rod 13 drives the second limit block 23 to exit from the limit hole 4, releasing the limit on the mounting plate 1. Then, the second motor 17 is activated, causing the rotating plate 3 to rotate 180°, rotating another empty take-up drum 5 to the take-up position. The electric push rod 13 is activated again, causing the second limit block 23 to insert into the corresponding limit hole 4, limiting and fixing the mounting plate 1. The cut waste material is rewound onto the new take-up drum 5, and then the first motor 16 in the new position is activated, and the new take-up drum 5 takes up the waste material. At this time, the operator can disassemble and replace the take-up drum 5 that is full of waste material. By rotating the threaded ring 7, the threaded ring 7 is unscrewed from the drum mounting shaft 8, and then the take-up drum 5 is removed from the drum mounting shaft 8. An empty take-up drum 5 is replaced, and then the threaded ring 7 is screwed back on to complete the replacement of the take-up drum 5.

[0054] The first limiting block 19 cooperates with the limiting groove 18 to prevent the winding drum 5 from sliding; the abutment plate 20 and the rotating plate 3 cooperate with the slider 21 and the sliding slot 22 to ensure the stable rotation of the drum mounting shaft 8.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
