Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, and more specifically to a raw material winding device for producing plastic bags. Background Art

[0002] Plastic bags are bags made of polypropylene, polyester, nylon and other main materials. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used mainly because of their advantages of being cheap, extremely light, large in capacity and easy to store. However, due to the disadvantages of plastic bags' extremely long degradation cycle and difficulty in handling, their production and use are banned in some countries.

[0003] During the production process of plastic bags, operators often use corresponding raw material winding devices to wind the raw materials. In actual use, although the existing winding devices have basic winding functions, most of them generally cut the raw materials without support. Since the raw materials have a certain toughness, the effect after cutting is poor, and long torn cuts are prone to occur, which reduces the cutting quality of the device. Therefore, it needs to be improved. Utility Model Content

[0030] A motion mechanism, the motion mechanism is arranged on the top of the fixed block 2;

[0031] Among them, the moving mechanism includes a No. 1 pneumatic cylinder 6, which is fixedly installed on the right side in front of the top of the fixed block 2.

The left side of the clamping plate 10 is fixedly connected with a connecting plate 11. The outer surface of the clamping plate 10 is movably connected to the inner side of the mounting plate 4. The left and right movement of the moving block 7 will cause the clamping plate 10 to move vertically up and down.

[0032] When the No. 1 pneumatic cylinder 6 starts to operate, the moving block 7 will move horizontally to the right, and the diagonal rod 8 will start to move. At this time, under the limiting effect of the vertical slot 5, the connecting block 9 drives the two clamping plates 10 to move vertically downward through the connecting plate 11.

[0033] Among them, the top of the inner cavity of the mounting frame 3 is fixedly connected with a No. 2 pneumatic cylinder 12, and the bottom of the No. 2 pneumatic cylinder 12 is fixedly connected with a cutting knife 13.

[0034] When the No. 2 pneumatic cylinder 12 starts to operate, the cutting blade 13 will move vertically up and down.

[0035] Among them, a No. 1 vertical plate 14 is fixedly connected to the front and rear sides of both sides of the middle of the top of the bottom plate 1, and a rotating roller 15 is movably sleeved between the No. 1 vertical plates 14. A No. 2 vertical plate 16 is fixedly connected to the front and rear sides of the right side of the top of the bottom plate 1, and a first winding roller 17 is movably sleeved between the No. 2 vertical plates 16.

[0036] Due to the design of the two rotating rollers 15, the raw material is kept in a horizontal state during the cutting process, thereby improving the stability of the cutting operation.

[0037] Among them, the front and rear sides of the left side of the top of the bottom plate 1 are fixedly connected with the third vertical plate 18, the top of the front side of the third vertical plate 18 is fixedly connected with the driving motor 19, and the other end of the output shaft of the driving motor 19 is fixedly sleeved with a rotating shaft 20.

[0038] When the driving motor 19 starts to operate, the rotating shaft 20 will rotate.

[0039] The other end of the rotating shaft 20 penetrates through the third vertical plate 18 and extends to the inside of the third vertical plate 18 and is movably sleeved with the inside of the third vertical plate 18 . The outer surface of the rotating shaft 20 is fixedly sleeved with a second winding roller 21 .

[0040] When the rotating shaft 20 starts to run, the second web roller 21 will rotate.

[0045] There are two telescopic rods 25 , the two telescopic rods 25 have the same size, and the outer surfaces of the two telescopic rods 25 are both smooth.

[0046] Such a design allows the telescopic rod 25 to move more smoothly inside the sleeve rod 24 .

[0047] The working principle and use process of this utility model:

[0048] First, start the drive motor 19 so that the rotating shaft 20 drives the second winding roller 21 to rotate. At this time, the raw material will be wound up. When the number of turns of the raw material is wound up increases and the raw material contacts the bottom of the pressure plate 26, the pressure plate 26 will drive the two telescopic rods 25 to move vertically upward under the limiting action of the sleeve rod 24, and the spring 27 will be in a compressed state. At this time, due to the elastic force of the spring 27, the pressure plate 26 can always press the raw material wrapped around the outer surface of the second winding roller 21, thereby improving the quality of the winding operation of the second winding roller 21.

[0049] When it is necessary to cut the raw materials, start the No. 1 pneumatic cylinder 6, so that the moving block 7 moves horizontally to the right, and drives the diagonal rod 8 to start moving. At this time, under the limiting effect of the vertical slot 5, the connecting block 9 drives the two clamping plates 10 to move vertically downward through the connecting plate 11, and finally realizes the support and fixation of the raw materials, thereby improving the quality and stability of the cutting operation of the device. At this time, start the No. 2 pneumatic cylinder 12, which will cause the cutting knife 13 to move vertically downward, and finally realize the cutting operation of the raw materials.
