Description

Technical Field

[0001] The present invention belongs to the technical field of waste plastic recycling, and in particular relates to a safe and environmentally friendly waste plastic recycling melting and granulation unit based on intelligent regulation. Background Art

[0002] The waste plastic recycling melting and granulation unit is a high-efficiency recycling processing equipment specially used for recycling and processing various types of waste plastics. It is widely used in plastic recycling companies, environmentally friendly material manufacturing industries and plastic product reuse systems. The unit uses a complete set of continuous thermal processing processes to first crush and pre-treat the waste plastics, and then use a heating device to perform high-temperature melting treatment. Subsequently, the plastic material flow is continuously extruded into strips through a melt extrusion mechanism, and cooled and solidified through a cooling system. Finally, it enters the pelletizing system to shear it into granular products, realizing the efficient conversion from waste materials to reusable plastic particles. The entire equipment has a compact structure and a high degree of automation. Not only does it significantly improve the processing efficiency, but it also has low energy consumption and is easy to operate. It helps to promote the resource utilization of waste plastics and reduce environmental pollution, which is in line with the development direction of green manufacturing and circular economy.

[0003] However, in the existing technology, this type of equipment still generally relies on manual operation in the strip extrusion stage after the plastic is melted. In particular, the strip pulling link requires the operator to manually pull the high-temperature strip out of the discharge nozzle and pass it through the subsequent cooling section or pressure wheel section. This manual intervention is not only labor-intensive, but also has high safety risks. Because the initial strip temperature is usually high, if the operation is not careful, it is easy to cause hand burns, posing a potential threat to the operator's health. At the same time, because the strip material has not been fully cooled initially, a slight delay or uneven force in the strip pulling process can easily cause problems such as adhesion and breakage between the strips, and even deformation of the strip head, which requires manual trimming. The trimmed waste not only affects the consistency of the product appearance, but also needs to be recycled and melted, which increases energy consumption and repeated processing costs, and reduces overall production efficiency. Therefore, how to achieve automatic guidance and pulling of molten plastic strips has become an important improvement direction for improving the intelligence level and safety performance of this type of unit.

[0004] Based on this, the present invention designs a safe and environmentally friendly waste plastic recycling melting and granulation unit based on intelligent regulation to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that after the plastic is melted and extruded into strips, the strip pulling operation usually relies on manual labor. However, due to the high temperature of the initially extruded plastic strips, there is a risk of burns from direct contact, which poses a safety hazard to the operator. In addition, during the manual strip pulling process, the plastic strips need to be guided through the lower rollers and smoothly guided out. The operation process is cumbersome and inefficient. Especially in the early stage of extrusion, the strips are often tightly gripped and pulled by the operator before they are completely cooled, which will cause adhesion and require trimming. The trimmed materials need to be reprocessed, resulting in material waste and repeated operations. A safe and environmentally friendly waste plastic recycling melting and granulation unit based on intelligent control is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A safe and environmentally friendly waste plastic recycling melting and granulation unit based on intelligent control, comprising a base plate, an extrusion assembly and a cooling pool mounted on the base plate, a control console mounted on the base plate, a discharge nozzle mounted on the output end of the extrusion assembly, a moving device mounted in the cooling pool, a clamping device fixedly connected to the upper surface of the moving device, a blocking device and a releasing device mounted in the cooling pool, and a monitoring device mounted on the front of the cooling pool; The moving device includes two guide rails, the two guide rails are fixedly connected in the cooling pool, the guide rails are provided with a connecting plate on the outside, two rotating shafts are installed in the connecting plate, one end of the rotating shaft is fixedly connected to a roller, and the roller is clamped in the guide rail; The clamping device includes a shell, a feed port is opened in the shell, a top plate is installed in the shell, a push plate is provided in the top plate, one side of the push plate is fixedly connected to the top plate, and the top plate is located below the feed port.

[0007] As a further description of the above technical solution: The mobile device further comprises a waterproof motor and a slider. The waterproof motor is fixedly connected to the outside of the connecting plate, and the output end of the waterproof motor is fixedly connected to the outside of one of the rotating shafts.

[0008] As a further description of the above technical solution: The shape of the slider is set to an irregular T-shape, the slider is fixedly connected in the connecting plate, and the slider is clamped in the guide rail.

[0009] As a further description of the above technical solution: The clamping device also includes a driving rod and a fixed plate, the driving rod is fixedly connected outside the frame, one side of the driving rod is fixedly connected to a force plate, the fixed plate is fixedly connected outside the frame, a return spring is installed in the fixed plate, and the return spring is fixedly connected to the top plate.

[0010] As a further description of the above technical solution: The shell is fixedly connected to the upper surface of the transverse plate, and the feed inlet is arranged just below the discharge nozzle.

[0011] As a further description of the above technical solution: The size of the top plate is smaller than the length and width of the interior of the shell, and a sliding connection is formed between the two. A sliding connection is also formed between the fixing plate and the shell.

[0012] As a further description of the above technical solution: The blocking device includes a connecting block, which is fixedly connected in the cooling pool. A sliding rod is provided in the connecting block, and a pull plate is fixedly connected to the upper surface of the sliding rod. The sliding rod is clamped in the force-bearing plate.

[0013] As a further description of the above technical solution: The releasing device includes a sliding frame, which is fixedly connected to the outside of the cooling pool. A slide is provided inside the slider, a pull rod is fixedly connected to the outside of the slide, one end of the pull rod is fixedly connected to a locking plate, a rotating rod is connected through the locking plate, a movable plate is provided outside the rotating rod, and a top column is fixedly connected to the lower surface of the movable plate.

[0014] As a further description of the above technical solution: A semicircular shell is fixedly connected to the top column, and the semicircular shell is overlapped on the lower surface of the pull rod.

[0015] As a further description of the above technical solution: The monitoring device includes a mounting plate, which is fixedly connected to the front of the cooling pool. A temperature sensor is fixedly connected to the back of the mounting plate, and a display screen is fixedly connected to the front of the mounting plate. A wire is connected between the temperature sensor and the display screen, and the temperature sensor is connected to the cooling pool through a sealing sleeve.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: The rotation of the roller drives the connecting plate and the slider to slide at a uniform speed along the guide rail, thereby driving the cross plate and the shell to move synchronously, realizing the clamping of the strip materials and driving them to move evenly in the cooling pool, thereby completing the process of clamping and automatic conveying of the strip materials.

[0017] 2. In the present invention, when the driving rod and the force-bearing plate move to the other end of the cooling pool with the moving device, an external force can be applied to the top column to push it, and the top column drives the movable plate to rotate around the rotating shaft, so that the pull rod in the locked state is smoothly released. At this time, the waterproof motor stops running, and the operator can pull the pull rod to drive the slide plate to slide in the slide frame, completing the unlocking process of the limit device. Subsequently, the top column applies a reverse thrust to the force-bearing plate, prompting the force-bearing plate to drive the driving rod and the push plate to move in the opposite direction along the frame, and at the same time drive the top plate back into the shell, and the top plate gradually breaks away from the contact position between the strip material and the feed port, releasing the clamping state of the strip material. The operator can now easily take the strip material out of the feed port for subsequent processing, thereby realizing the release of the clamping limit and the removal of the strip material by simply pulling the pull rod, which significantly improves the convenience and safety of operation.

[0018] 3. In the present invention, during the processing, the water temperature is collected in real time by using a temperature sensor installed in the cooling pool. The temperature sensor transmits the monitoring data to the display screen through a wire. The operator can view the temperature status in the cooling pool in real time through the display screen so as to replace, replenish or perform other adjustment operations on the cooling water according to actual needs. This structure effectively ensures the stability and safety of the cooling process and prevents fluctuations in the cooling effect from affecting the molding quality of the plastic strips.

The top plate 705 and the push plate 704 are fixedly connected, and the push plate 704 slides in the shell 701 with the help of the top plate 705, thereby realizing directional pushing of the strip material. This matching structure makes the thrust transmission more direct and reliable. Driven by the return spring 709, the top plate 705 drives the push plate 704 to move synchronously, effectively pushing the end of the strip material into the clamping position, thereby improving the positioning efficiency and clamping accuracy of the strip material.

[0023] Specifically, such as Figure 2-Figure 6As shown, the mobile device 6 also includes a waterproof motor 605 and a slider 606. The waterproof motor 605 is fixedly connected to the outside of the connecting plate 602. The output end of the waterproof motor 605 is fixedly connected to the outside of one of the rotating shafts 603. The shape of the slider 606 is set to an irregular T-shape.

Through the sliding connection between the slider 606 and the guide rail 601, the connecting plate 602 can move smoothly on the guide rail 601. This matching structure effectively avoids the unstable operation caused by deflection or jamming during the movement, thereby improving the smoothness and guidance of the entire clamping system in the underwater cooling environment. The clamping device 7 also includes a driving rod 706 and a fixing plate 708. The driving rod 706 is fixedly connected to the outside of the frame 703.

One end of the pull rod 903 is fixedly connected to a locking plate 904, and a rotating rod 905 is connected through the locking plate 904. The outer cover of the rotating rod 905 is provided with a movable plate 906.

The upper end of the top column 907 is fixedly connected to the semicircular shell 908, and the semicircular shell 908 overlaps and covers the bottom of the pull rod 903. When the top column 907 is pushed by an external force, it drives the semicircular shell 908 to rotate in a single direction around the rotating shaft 603, so that it disengages from the pull rod 903, completing the limited release. This matching structure only allows the top column 907 to drive the semicircular shell 908 to rotate to one side through the structural angle and gravity, thereby achieving a one-way unlocking effect.

[0026] Working principle: when in use: the strip material is extruded from the discharge nozzle 4 and enters the cooling pool 5, and multiple strip materials enter the feed port 702 synchronously. The operator can pull the pull plate 803, so that the pull plate 803 drives the slide bar 802 to slide in the connecting block 801, so that the slide bar 802 moves away from the force-bearing plate 707, and the obstruction of the force-bearing plate 707 is released. After the force-bearing plate 707 loses its support, the top plate 705 is driven to slide forward in the shell 701 under the action of the return spring 709, and at the same time, the push plate 704 is pushed to slide along the frame 703, pushing the strip material forward and making its end portion be stuck between the feed port 702 and the shell 701, completing the initial positioning, and then starting the waterproof motor 605, driving the rotating shaft 603 to rotate and drive the roller 604 to roll and move in the guide rail 601 groove, thereby pushing the connecting plate 602 and the slider 606 to slide along the guide rail 601, and driving the cross plate 607 and the shell 701 to move synchronously. After the lever 706 is released, the push rod 903 is released, and the push rod 903 is released to the left and right sides of the movable plate 904.
