Description

Technical Field

[0001] The utility model relates to the technical field of plastic crushing, in particular to a plastic bag crushing device. Background Art

[0002] The plastic bag crushing device is mainly used to crush discarded plastic bags. The use of the plastic bag crushing device facilitates the unified recycling of crushed plastics. The crushed plastics can be reused by using a certain recycling process to achieve the purpose of turning waste into treasure.

[0003] According to the existing Chinese patent CN 220373686 U, a plastic bag crushing device comprises a crushing box, a bearing is installed inside the crushing box, a driving shaft is sleeved inside the bearing, one end of the driving shaft is fixedly connected to a driving gear, a driving roller is fixedly sleeved outside the driving shaft, and a cutting blade is fixedly connected to the outside of the driving roller. The plastic bag crushing device drives the driving shaft, the driving roller, the cutting blade and the driving gear to rotate by starting the motor, and the driving gear drives the driven gear to rotate, thereby driving the driven cutting roller to rotate, so as to facilitate the crushing of plastic bags. The combined design of the cutting blade and the driven cutting roller can prevent the plastic bags from being entangled on the outside of a single cutting roller and unable to be crushed, and effectively improves the plastic cutting and crushing efficiency; by connecting the water inlet pipe to a water source and filling it with water, the inside of the crushing box after use can be rinsed to prevent the plastic sheets from being electrostatically attached to the inner wall of the crushing box and being difficult to discharge, and by starting the motor to drive the fan blades to rotate, wind can be generated to blow the plastic sheets out quickly. The device uses water to flush the inside of the crushing box, solving the problem that plastic flakes are difficult to discharge from the crushing box due to electrostatic adhesion. However, this operation consumes water resources, and water and plastic flakes are discharged at the same time, making it inconvenient to uniformly recycle the crushed plastics.

[0004] Therefore, it is necessary to provide a plastic bag crushing device to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[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] The utility model provides two technical solutions:

[0025] Figure 1 to Figure 2 The first embodiment is shown: a plastic bag crushing device includes a crushing component for crushing plastic bags, a base 1 is fixedly connected below the crushing component, a water filter component for separating crushed plastic from water is slidably connected to the inner wall of the base 1, a discharge pipe 2 is fixedly connected below the crushing component, the end of the discharge pipe 2 facing away from the crushing component passes through the base 1 and is connected to the water filter component, and an extrusion component for squeezing, draining and stacking the crushed plastic in the water filter component is installed on the base 1.

[0026] The crushing assembly includes a crusher 3 fixed above a base 1, a water pump 4 is fixedly connected to one side of the base 1, the liquid outlet of the water filter assembly is connected to the liquid inlet of the water pump 4 through a water pipe, and the liquid outlet of the water pump 4 is connected to the liquid inlet of the crusher 3 through a water pipe.

[0027] The water filter assembly includes a water tank 5 fixedly connected to the base 1, a water filter box 6 is slidably connected above the water tank 5, a water filter hole 7 is provided at the bottom of the water filter box 6, the water filter box 6 is slidably connected to the inner wall of the base 1, and a handle 15 is fixedly connected to one side of the water filter box 6 close to the motor 8.

[0028] This application sets up a water tank 5, a water filter box 6, a water filter hole 7, a discharge pipe 2, a water pump 4 and a water pipe, so that the water used to flush into the crusher 3 to prevent static electricity can be recycled, and the crushed plastic falls onto the water filter box 6 together with the water. The water will flow into the water tank 5 through the water filter hole 7, and the water will be sucked by the water pump 4 for recycling, thereby reducing the cost of the device operation and increasing the economic benefits.

[0029] Figure 3 to Figure 4 A second embodiment is shown, which mainly differs from the first embodiment in that an extrusion assembly includes a motor 8 fixedly connected to an inner wall of a base 1, a screw 9 is rotatably connected to the inner wall of the base 1 through a bearing, an output end of the motor 8 is fixed to one end of the screw 9, a first mounting block 10 is threadedly connected to an outer wall of the screw 9 through a threaded hole, an electric telescopic rod 11 is fixedly connected to the inner wall of the first mounting block 10, an extrusion plate 12 is fixedly connected to the protruding end of the electric telescopic rod 11, and the electric telescopic rod 11 is slidably connected to the inner wall of the base 1.

[0030] The inner wall of the base 1 is fixedly connected with a slide bar 13 , the outer wall of the slide bar 13 is slidably connected with a second mounting block 14 , and the second mounting block 14 is fixed to the electric telescopic rod 11 .

[0031] This application sets up an extrusion component. When broken plastics accumulate on the water filter box 6, it is inconvenient for the water to be discharged into the water tank 5 below. The extrusion plate 12 is used to squeeze the plastic sheets to one side, which can not only discharge the water between the gaps of the plastic sheets, but also assist the water to flow into the water tank 5, which is practical.

[0032] Working principle:

[0033] Crusher 3 adopts the plastic bag crushing device in CN 220373686 U, which is the prior art and will not be described in detail.

[0034] The plastic to be crushed and water are added into the crusher 3 at the same time. The water is used to prevent the crushed plastic pieces from adhering to the inner wall of the crusher 3 due to static electricity, making it difficult to discharge.

[0035] The crushed plastic sheets and water will be discharged to the water filter box 6 through the discharge pipe 2, and the water will flow into the water tank 5 through the filter water hole 7. When too many plastic sheets are accumulated on the water filter box 6, it is easy to cause the water to be unable to flow into the water tank 5 below. At this time, an extrusion component is used.

[0036] The motor 8 is driven intermittently, so that the screw rod 9 rotates and drives the first mounting block 10 to move toward the direction close to the motor 8, and the electric telescopic rod 11 also moves accordingly, thereby driving the extrusion plate 12 to stack and extrude the plastic sheets, so that the plastic sheets discharge the water in the gap. The stacking of plastic sheets prevents the plastic sheets from covering the water filter hole 7 and affecting the drainage. After the extrusion is completed, the screw rod 9 is reversed to make the extrusion plate 12 return to its position away from the motor 8; while the electric telescopic rod 11 moves, the second mounting block 14 slides on the outer wall of the slide rod 13 accordingly.

[0037] When the plastic sheets in the water filter box 6 are difficult to drain by squeezing and stacking, the electric telescopic rod 11 is retracted to make the squeezing plate 12 rise and leave the water filter box 6, and the water filter box 6 is pulled out from the inner wall of the base 1 using the handle to uniformly process the broken plastic sheets; then the empty water filter box 6 is replaced on the top of the water tank 5, and the squeezing plate 12 is lowered using the electric telescopic rod 11, and the device can continue to be used.
