Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cooling and cutting device for processing waste plastics. Background Art

[0002] The cooling cutting device for waste plastic processing is a device used to cut processed (such as melted, softened) plastics during the waste plastic recycling process, and is specially designed with a function of cooling the cutting blade.

[0003] Most of the existing cooling and cutting devices for processing waste plastics use spraying to cool the cutting blades, but this spraying method has a significant problem, that is, the spray water is discharged after being used only once, and there is a lack of an effective recycling mechanism, which not only leads to a waste of water resources and increases production costs, but also creates an unnecessary burden on the environment. At the same time, when these devices are cutting plastics, the plastics are prone to displacement, which not only affects the cutting accuracy and efficiency, but also may cause equipment damage or safety accidents. For example, the cutting blade may be damaged by collision, and even cause danger to the operator. Therefore, we propose a cooling and cutting device for processing waste plastics. Utility Model Content

[0004] The purpose of the utility model is to provide a cooling and cutting device for processing waste plastics, so as to solve the problem that most of the existing cooling and cutting devices for processing waste plastics proposed in the above background technology adopt a spraying method to cool the cutting knife, but this spraying method has a significant problem, that is, the spraying water is discharged after being used only once, and there is a lack of an effective recycling mechanism, which not only leads to a waste of water resources and increases production costs, but also creates an unnecessary burden on the environment. At the same time, when these devices cut plastics, the plastics are prone to displacement, which not only affects the cutting accuracy and efficiency, but also may cause equipment damage or safety accidents. For example, the cutting knife may be damaged due to collision, and even cause danger to the operator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling and cutting device for processing waste plastics, comprising a base, a gantry is fixedly installed on the top of the base, a water tank is opened inside the base, a cylinder is fixedly installed at the center of the top of the gantry, a cross plate is arranged at the center of the lower end of the gantry, a cutting knife is fixedly installed at the center of the bottom of the cross plate, spray pipes are fixedly installed on both sides of the top of the gantry corresponding to the cylinder respectively, mounting tubes are fixedly installed at the four corners of the bottom of the cross plate, a spring is fixedly connected to the inner top of the mounting tube, and the lower ends of the four springs are fixedly connected to telescopic rods, a pressing plate is arranged at the center of the upper end of the base, a water pump is fixedly installed on one side of the gantry, and a water suction pipe and a water inlet pipe are respectively arranged on the top and bottom of the water pump.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The cooling and cutting device for processing waste plastics is designed with a cross plate, a mounting tube, a spring, a telescopic rod and a pressing plate. When the cylinder drives the cross plate and drives the cutting knife to move downward to cut the plastic, the pressing plate will contact the plastic in advance. Due to the elastic effect of the spring, the pressing plate can adaptively adjust the pressure between the plastic and the pressing plate to ensure that the plastic is firmly fixed before cutting. The cross plate continues to move downward to drive the cutting knife to cut the plastic under the condition that the pressing plate presses the plastic. This design not only avoids the displacement of the plastic during the cutting process, but also improves the cutting accuracy and stability, and effectively reduces the plastic fragments that may be generated during the cutting process, thereby significantly improving the recycling quality of waste plastics. The design of the water reservoir, water pump, water suction pipe, water inlet pipe and spray pipe allows the water after spraying to flow back into the water reservoir through the leakage hole on the base, forming a closed loop of water circulation.

[0015] The cylinder 4 is fixedly connected to a piston rod through its bottom output end, the lower end of the piston rod passes through the outside of the gantry 3 and is fixedly connected to the center of the top of the cross plate 5, and the piston rod of the cylinder 4 drives the cross plate 5 and the cutting knife 6 to move up and down to realize the cutting function.

[0016] The lower ends of the four telescopic rods 9 respectively penetrate the outside of the four mounting tubes 7 and are fixedly connected to the four corners of the top of the pressing plate 10. Through the combination of the telescopic rods 9 and the springs 8, it is ensured that the pressing plate 10 can adaptively adjust the pressure between it and the plastic to press the plastic and prevent displacement of the plastic during cutting.

[0017] A rectangular groove is provided at the center of the top of the pressing plate 10, and the diameter of the rectangular groove is greater than the diameter of the cutting knife 6. A cutting groove 11 is provided at the center of the top of the base 1. While the pressing plate 10 presses the plastic, the cutting knife 6 can penetrate the rectangular groove for cutting.

[0018] A leakage hole 12 is provided at the top of the base 1, a filter screen is fixedly connected to one side of the water reservoir 2, a drain pipe is fixedly connected to the bottom of the other side of the water reservoir 2, one end of the drain pipe passes through the outside of the base 1, and a drain valve is fixedly installed on the top of the drain pipe. The leakage hole 12 allows the water after spraying to flow back to the water reservoir 2 through the leakage hole 12 to achieve water recycling. The filter screen can filter impurities and plastic particles that may be contained in the water after spraying to maintain the cleanliness of the spraying water. When it is necessary to clean the water reservoir 2 or replace the spraying water, the water in the water reservoir 2 can be discharged by opening the drain valve.

[0019] The top of the horizontal plate 5 is provided with grooves corresponding to the upper ends of the two spray pipes 16. The lower ends of the two spray pipes 16 pass through the outside of the gantry 3 and extend to the outside of the two grooves. The lower ends of the two spray pipes 16 are symmetrically arranged. When the horizontal plate 5 moves downward, the spray pipes 16 can pass through the grooves, thereby not hindering the cutting work.

[0020] One end of the water pumping pipe 14 is fixedly connected to the water pumping end at the bottom of the water pump 13, the other end of the water pumping pipe 14 passes through the interior of the base 1 and is fixedly connected to the bottom of one side of the water reservoir 2, one end of the water inlet pipe 15 is fixedly connected to the water outlet end at the top of the water pump 13, and the bottom of the other end of the water inlet pipe 15 is fixedly connected to the upper ends of the two spray pipes 16 respectively.

[0021] Working principle: First, place the waste plastic to be cut at the center of the top of the base 1, that is, below the pressing plate 10, so that the cutting position of the plastic is aligned with the cutting groove 11, and control the cylinder 4 to push the horizontal plate 5 downward, and the horizontal plate 5 drives the cutting knife 6 and the pressing plate 10 to move downward at the same time. Since the height of the pressing plate 10 is lower than the cutting knife 6, the pressing plate 10 will pre-press the plastic. When the horizontal plate 5 continues to move downward, the telescopic rod 9 moves upward in the installation tube 7 and compresses the spring 8. Due to the characteristics of the spring 8, the horizontal plate 5 can continue to drive the cutting knife 6 to move downward and complete the Cutting. After the cutting is completed, the cylinder 4 drives the horizontal plate 5 to reset, the spring 8 is loosened, the installation tube 7 pulls the telescopic rod 9 and makes the pressing plate 10 move upward and leave the plastic. At this time, the operator removes the cut plastic, and then starts the water pump 13 to pump water from the water reservoir 2 through the pumping pipe 14. Under the operation of the water pump 13, the water enters the two spray pipes 16 through the water inlet pipe 15, and the two sides of the cutting knife 6 are sprayed and cooled through the spray pipes 16. The water after spraying falls and enters the water reservoir 2 again through several leakage holes 12, thereby achieving the effect of circulating spraying, and the operation is convenient.

[0022] In summary: the cooling and cutting device for processing waste plastics is designed with a transverse plate 5, a mounting tube 7, a spring 8, a telescopic rod 9 and a pressing plate 10. When the cylinder 4 drives the transverse plate 5 and drives the cutting knife 6 to move downward to cut the plastic, the pressing plate 10 will contact the plastic in advance. Due to the elastic effect of the spring 8, the pressing plate 10 can adaptively adjust the pressure between the plastic and the pressing plate 10 to ensure that the plastic is firmly fixed before cutting. The transverse plate 5 continues to move downward, driving the cutting knife 6 to cut the plastic under the condition that the pressing plate 10 presses the plastic. This design not only avoids the displacement of the plastic during the cutting process, but also improves the cutting accuracy and stability, effectively reduces the plastic fragments that may be generated during the cutting process, and thus significantly improves the recycling quality of waste plastics. The design of the water reservoir 2, the water pump 13, the water suction pipe 14, the water inlet pipe 15 and the spray pipe 16 allows the water after spraying to flow back into the water reservoir 2 through the leakage hole 12 on the base 1, forming a closed loop of water circulation. This design not only saves water resources and reduces production costs, but also reduces pollution to the environment.
