Description
Technical Field
[0001] The utility model relates to the technical field of plastic bag processing, and more specifically, to a dissolving device for plastic bag processing. Background Art
[0002] Plastic bags are made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are widely used because of their low cost, extremely light weight, large capacity, and easy storage. However, plastic bags have a very long degradation cycle and are difficult to handle, so they are also considered one of the important sources of environmental pollution.
[0003] Although the existing plastic bag dissolving devices have played a certain role in the field of environmental protection, there are indeed some obvious disadvantages in the actual application process. These devices usually place the plastic bag and the dissolving agent into the mixing barrel in turn, and mix and stir the two through the stirring device, in order to achieve full contact between the plastic bag and the dissolving agent, thereby achieving the decomposition of the plastic bag. However, the limitation of this method is that it ignores the impact of the diversity of plastic bag size and shape on the dissolution process. Plastic bags vary in size and shape, which leads to differences in their surface area and speed when they contact and react with the dissolving agent. Smaller plastic bags have a relatively small surface area and limited contact area with the dissolving agent, so they take longer to completely dissolve. Although larger plastic bags have a larger surface area, they may not be evenly distributed in the mixing barrel due to their large size, resulting in insufficient concentration of the dissolving agent in some areas, which also affects the dissolution effect. In addition, the design of the stirring device may also affect the dissolution effect. If the stirring force of the stirring device is not enough or the stirring method is unreasonable, the plastic bag and the dissolving agent may not be fully mixed, resulting in poor dissolution effect. In addition, the heat and friction generated during the stirring process may also have an adverse effect on the decomposition process of plastic bags. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figures 1 to 6 As shown, the utility model provides a dissolving device for processing plastic bags, comprising a mixing box 1, a crushing box 2 is fixedly installed on the top of the mixing box 1, a rectangular groove 31 is opened between the crushing box 2 and the mixing box 1, a crushing roller 3 and a crushing roller 4 are movably installed inside the crushing box 2, one end of the crushing roller 3 and the crushing roller 4 are fixedly installed with a connecting shaft 5, one end of one connecting shaft 5 is fixedly installed with a main gear 6, a driving motor 8 is fixedly installed on the surface of the main gear 6, and a slave gear 7 is fixedly installed on one end of the other connecting shaft 5, the main gear 6 and the slave gear 7 are in a meshing state, and two guide plates 30 are fixedly installed on the inner wall of the crushing box 2 and are symmetrically distributed;
[0025] When in use, the staff starts the driving motor 8, and the power generated by the driving motor 8 causes the main gear 6 to rotate. Since the slave gear 7 is meshed with the main gear 6, the main gear 6 drives the slave gear 7 to rotate synchronously while rotating, so that the crushing roller 13 and the crushing roller 24 rotate relatively. At this time, the plastic bag raw material is poured from the top of the crushing box 2 into the crushing roller 3 and the crushing roller 24 to be crushed. The crushed plastic slides along the surface of the guide block 32 to the inside of the rectangular groove 31 and finally falls into the inside of the mixing box 1;
[0026] The power of the driving motor 8 causes the main gear 6 to rotate, and the meshing between the main gear 6 and the slave gear 7 drives the slave gear 7 to rotate synchronously, so that the crushing roller 3 and the crushing roller 24 rotate relatively, and the plastic is crushed by the relative movement between the crushing roller 3 and the crushing roller 24. Compared with the traditional device, this device can increase the surface area of the broken plastic bag, which means that the contact area with the solvent is also increased accordingly, which helps to speed up the dissolution process. At the same time, smaller fragments are more easily penetrated and dissolved by the solvent, thereby reducing the time and energy required for dissolution. Large pieces of plastic bags may cause additional wear or damage to the processing equipment. The volume of the broken plastic bags becomes smaller, which can reduce this mechanical pressure and extend the service life of the equipment.
[0027] Among them, the bottom of the mixing box 1 is movably installed with a main gear 29 and a slave gear 210, and the main gear 29 and the slave gear 210 are in a meshing state, wherein the bottom of the main gear 29 is fixedly installed with a driving motor 215, and the tops of the main gear 29 and the slave gear 210 are fixedly installed with a connecting shaft 211, and the top of the connecting shaft 211 is fixedly installed with a rotating rod 12, and the surface of one rotating rod 12 is fixedly installed with a spiral stirring blade 13, and the surface of the other rotating rod 12 is fixedly installed with a spiral stirring blade 214;
[0028] When the broken plastic bags enter the mixing box 1, a solvent is added to the mixing box 1. At this time, the staff starts the driving motor 2 15. The power generated by the driving motor 2 15 causes the main gear 2 9 to rotate. Since the main gear 2 9 and the slave gear 2 10 are in meshing state, the main gear 2 9 will cause the slave gear 2 10 to rotate synchronously while rotating. Then, the spiral stirring blades 1 13 and the spiral stirring blades 2 14 on the surfaces of the two groups of rotating rods 12 rotate relative to each other. Through the relative rotation of the spiral stirring blades 1 13 and the spiral stirring blades 2 14, the broken plastic bags and the solvent in the mixing box 1 are fully mixed. The generated waste gas passes through the inside of the outlet pipe 21 and is purified by the activated carbon plate 22 before being discharged.
[0029] The power of the driving motor 2 15 makes the main gear 2 9 rotate synchronously with the slave gear 2 10 meshing with the main gear 2 9, so that the spiral stirring blade 1 13 on the surface of the rotating rod 12 and the spiral stirring blade 2 14 on the surface of the other group of rotating rods 12 rotate relative to each other, so that the dissolved liquid and the crushed plastic are fully stirred and mixed, and the flying exhaust gas generated thereafter passes through the inside of the exhaust pipe 21 and is discharged after being purified by the activated carbon plate 22. Compared with the traditional device, this device can ensure that the two groups of rotating rods 12 maintain a stable relative position and motion trajectory during the rotation process, thereby ensuring the consistency and uniformity of the stirring effect. At the same time, by accurately designing parameters such as the number of teeth and module of the gears, the precise rotation speed and direction control of the stirring device can be achieved, which helps to achieve precise control of the stirring process of the dissolved liquid and ensure that the stirring effect meets the process requirements. In addition, the two groups of rotating rods 12 rotate relative to each other through gear transmission, which can produce a more complex stirring flow, which helps to mix and disperse the substances in the dissolved liquid more quickly, thereby improving the uniformity and stability of the dissolved liquid, thereby improving the quality and performance of the product.

[0031] The dissolved plastic is driven by the power of the motor 3 19 to rotate the spiral conveying blade 18 on the surface of the movable rod 17, so that the dissolved plastic will be synchronously moved along the space between the spiral conveying blades 18 and 18, and finally moved to the top of the discharge pipe 20, and then collected by a collecting device, which can evenly discharge and collect the material, thereby improving efficiency.
[0032] Among them, three groups of legs 28 are fixedly installed at the bottom of the mixing box 1, and leg pads 29 are fixedly installed at the bottom of the three groups of legs 28;
[0033] Three groups of legs 28 are fixedly installed at the bottom of the mixing box 1, and leg pads 29 are fixedly installed at the bottom of the three groups of legs 28. The use of the leg pads 29 can disperse the pressure from above, thereby improving the stability of the device when in use.
[0034] The top of the mixing box 1 is fixedly provided with an air outlet pipe 21, and two activated carbon plates 22 are arranged inside the air outlet pipe 21 and are distributed up and down;
[0035] An air outlet pipe 21 is fixedly installed on the top of the mixing box 1. Two activated carbon plates 22 are arranged inside the air outlet pipe 21 and are distributed up and down. The activated carbon plates 22 can absorb pollutants in the exhaust gas, thereby ensuring the purity of the gas and will not aggravate air pollution to a certain extent.
[0036] Among them, an observation window 27 is fixedly installed on the front of the mixing box 1, and the observation window 27 is made of glass. A guide block 32 is fixedly installed on the top of the mixing box 1;
[0037] An observation window 27 is fixedly installed on the front of the mixing box 1. The observation window 27 is made of glass. The glass is transparent, so that the staff can observe the outside better. A guide block 32 is fixedly installed on the top of the mixing box 1. The guide block 32 can guide the broken plastic bags to avoid accumulation.
[0038] A slide groove 23 is provided on the top inner wall of the crushing box 2, and a cover plate 24 is movably installed inside the slide groove 23;
[0039] A chute 23 is provided on the top inner wall of the crushing box 2, and a cover plate 24 is movably installed inside the chute 23. The cooperation between the chute 23 and the cover plate 24 can prevent dust in the external air from entering the interior of the mixing box 1, thereby ensuring the quality of dissolution.
[0040] A motor protection cover 25 is provided at the bottom of the main gear 2 9, and the drive motor 2 15 is located inside the motor protection cover 25, and a heat dissipation hole 26 is provided on the surface of the motor protection cover 25;
[0041] A motor protection cover 25 is provided at the bottom of the main gear 2 9, and the drive motor 2 15 is located inside the motor protection cover 25. The use of the motor protection cover 25 can protect the drive motor 2 15 inside from being damaged by collision. Heat dissipation holes 26 are opened on the surface of the motor protection cover 25, and the heat dissipation holes 26 can quickly dissipate the heat of the drive motor 2 15.
[0042] The working principle and use process of this utility model:
[0043] When in use, the staff starts the driving motor 8, and the power generated by the driving motor 8 makes the main gear 6 rotate. Since the slave gear 7 is meshed with the main gear 6, the main gear 6 drives the slave gear 7 to rotate synchronously while rotating, so that the crushing roller 13 and the crushing roller 24 rotate relative to each other. At this time, the plastic bag raw material is poured from the top of the crushing box 2 into the crushing roller 3 and the crushing roller 24 to be crushed. The crushed plastic slides along the surface of the guide block 32 to the inside of the rectangular groove 31 and finally falls into the inside of the mixing box 1.
[0044] After the broken plastic bags enter the mixing box 1, a solvent is added to the mixing box 1. At this time, the staff starts the driving motor 2 15. The power generated by the driving motor 2 15 causes the main gear 2 9 to rotate. Since the main gear 2 9 and the slave gear 2 10 are in meshing state, the main gear 2 9 will cause the slave gear 2 10 to rotate synchronously while rotating. Then, the spiral stirring blades 1 13 and the spiral stirring blades 2 14 on the surfaces of the two groups of rotating rods 12 rotate relative to each other. Through the relative rotation of the spiral stirring blades 1 13 and the spiral stirring blades 2 14, the broken plastic bags and the solvent in the mixing box 1 are fully mixed. The generated waste gas passes through the inside of the exhaust pipe 21 and is purified by the activated carbon plate 22 before being discharged.
