Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granulation equipment technology, and in particular to a discharge conveying mechanism for a granulator. Background Technology
[0002] In the granulation production process of plastics, rubber, and chemicals, calendering granulators are key equipment for extruding molten materials into strips and cutting them into granules. As the final stage of the granulation process, the cooling efficiency and conveying stability of the discharge conveyor belt directly affect product quality and production efficiency.
[0003] The existing pellet mill's discharge conveying mechanism has low pellet cooling efficiency. High-temperature pellets accumulate on the conveyor belt, resulting in slow heat dissipation, which seriously affects the efficiency of subsequent packaging or storage. Furthermore, pellet sticking occurs frequently, with some molten pellets easily adhering to the surface of the conveyor belt, causing material accumulation or even blockage. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a discharge conveying mechanism for a granulator.
[0005] This utility model is achieved by the following technical solution: a discharge conveying mechanism for a granulator, including a support frame, a conveyor belt rotatably connected inside the support frame, a refrigeration device inside the support frame, a support plate fixedly connected to the top of the support frame, a fan rotatably connected inside the support plate, and a lifting device on the top of the support frame.
[0006] Through the above technical solution, four fans are symmetrically distributed to accelerate airflow and form a uniform airflow field; they blow air onto the surface of the conveyor belt to enhance convective heat dissipation and assist the cooling device in cooling down; and they work with the guide plate to control the airflow direction and avoid direct blowing that could cause particles to scatter.
[0007] As a further improvement to the above solution, the number of fans is set to four, and the four fans are evenly distributed symmetrically around the center of the top of the support frame.
[0008] As a further improvement to the above solution, the refrigeration device includes a circulating water tank, with an outlet pipe connected to the front end of the circulating water tank, a water storage tank connected to one end of the outlet pipe, a water pump fixedly connected to the top of the water storage tank, an inlet pipe fixedly connected to the top of the water pump, and a condenser fixedly connected to the front end of the water storage tank.
[0009] As a further improvement to the above solution, the circulating water tank is located inside the support frame, the surface of the circulating water tank is fixedly connected to the inside of the support frame, and one end of the water inlet pipe is connected to the front end of the water storage tank.
[0010] As a further improvement to the above solution, the lifting device includes a support rod, a lead screw is rotatably connected inside the support rod, a lifting plate is threadedly connected to the surface of the lead screw, a guide rod is slidably connected inside the lifting plate, a sliding groove is opened at the front end of the lifting plate, a guide plate is slidably connected to the inner wall of the sliding groove, a fixing rod is threadedly connected inside the guide plate, and a handle is fixedly connected to the top of the lead screw.
[0011] Through the above technical solution, the fixing rod is connected to the lifting plate by threads. After tightening, the position of the guide plate is locked to prevent shaking during the conveying process; when loosened, the posture of the guide plate can be adjusted. The sliding groove is opened at the front end of the lifting plate, allowing the guide plate to slide laterally or rotate slightly in the groove, so as to realize the fine adjustment of the angle or position of the guide plate. The guide plate guides the airflow direction generated by the fan, and the wind speed is controlled by adjusting the height (distance from the conveyor belt) to avoid excessive wind force blowing away particles. By finely adjusting the angle, the airflow flows smoothly, suppressing particle splashing, and enhancing the cooling effect.
[0012] As a further improvement to the above solution, the support rod is located at the top of the support frame, and the bottom of the support rod is fixedly connected to the top of the support frame.
[0013] As a further improvement to the above solution, the support rod has grooves at its front and rear ends, and the grooves at the front and rear ends of the support rod are slidably connected to the front and rear ends of the lifting plate. A guide rod is fixedly connected inside the support rod, and the guide rod is located at the rear end of the lead screw.
[0014] With the above technical solution, the guide rod is fixed inside the support rod and inserted into the sliding hole of the lifting plate, which restricts the lifting plate to move only vertically, avoids the screw being subjected to eccentric force, and ensures stable adjustment.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention features a circulating water tank. The coolant in the circulating water tank within the support frame flows into the storage tank through the outlet pipe, and the water pump pumps it back through the inlet pipe. Along the way, a condenser cools the coolant. The low-temperature coolant circulates and absorbs heat from the materials and the conveyor belt, preventing materials from sticking together at high temperatures and cooling the conveying environment.
[0017] This invention features a lifting plate. By rotating the handle at the top of the lead screw, the lead screw rotates, causing the lifting plate, which is threadedly connected to the lead screw, to slide up and down along the support rod under the limit of the guide rod, thus adjusting the height of the guide plate. If fine adjustment of the guide plate position is required, the fixing rod can be loosened, the guide plate can be slid in the sliding groove, and then tightened again to fix it. This allows for flexible adjustment of the guide plate height and position, effectively guiding airflow, preventing particle scattering, and reducing material loss and environmental pollution.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Example:
[0027] Please combine Figure 1-5 The discharge conveying mechanism of a granulator according to this embodiment includes a support frame 1, a conveyor belt 2 rotatably connected inside the support frame 1, a cooling device 3 installed inside the support frame 1, a support plate 4 fixedly connected to the top of the support frame 1, a fan 5 rotatably connected inside the support plate 4, and a lifting device 6 installed on the top of the support frame 1.
[0028] There are four fans 5, which are symmetrically and evenly distributed around the top center of the support frame 1.
[0029] The refrigeration device 3 includes a circulating water tank 301, with an outlet pipe 302 connected to the front end of the circulating water tank 301. One end of the outlet pipe 302 is connected to a storage tank 303. A water pump 304 is fixedly connected to the top of the storage tank 303, and an inlet pipe 305 is fixedly connected to the top of the water pump 304. A condenser 306 is fixedly connected to the front end of the storage tank 303. The coolant in the circulating water tank 301 in the support frame 1 flows into the storage tank 303 through the outlet pipe 302. The water pump 304 pumps it back through the inlet pipe 305. During the process, the condenser 306 cools the coolant. The low-temperature coolant circulates and absorbs heat from the materials and the conveyor belt 2, preventing the materials from sticking together at high temperatures and cooling the conveying environment.
[0030] The circulating water tank 301 is located inside the support frame 1. The surface of the circulating water tank 301 is fixedly connected to the inside of the support frame 1. One end of the water inlet pipe 305 is connected to the front end of the water storage tank 303.
[0031] The lifting device 6 includes a support rod 601, a lead screw 602 rotatably connected inside the support rod 601, a lifting plate 603 threadedly connected to the surface of the lead screw 602, a guide rod 604 slidably connected inside the lifting plate 603, a sliding groove 605 at the front end of the lifting plate 603, a guide plate 606 slidably connected to the inner wall of the sliding groove 605, a fixing rod 607 threadedly connected inside the guide plate 606, and a handle 608 fixedly connected to the top of the lead screw 602. When it is necessary to adjust the height of the guide plate 606, the handle 608 at the top of the lead screw 602 is rotated, causing the lead screw 602 to rotate, so that the lifting plate 603 threadedly connected to the lead screw 602 slides up and down along the support rod 601 under the limit of the guide rod 604, thereby adjusting the height of the guide plate 606. If it is necessary to fine-tune the position of the guide plate 606, the fixing rod 607 can be loosened, the guide plate 606 can be slid in the sliding groove 605, and then tightened.
[0032] The support rod 601 is located at the top of the support frame 1, and the bottom of the support rod 601 is fixedly connected to the top of the support frame 1.
[0033] The support rod 601 has grooves at its front and rear ends. The grooves at the front and rear ends of the support rod 601 are slidably connected to the front and rear ends of the lifting plate 603. A guide rod 604 is fixedly connected inside the support rod 601. The guide rod 604 is located at the rear end of the lead screw 602.
[0034] The implementation principle of the discharge conveying mechanism of a granulator in this embodiment is as follows: the conveyor belt 2 rotates in the support frame 1 to convey the granulated material produced by the granulator. The coolant in the circulating water tank 301 in the support frame 1 flows into the storage tank 303 through the outlet pipe 302. The water pump 304 pumps it back through the inlet pipe 305. During the process, the condenser 306 cools the coolant. The low-temperature coolant circulates and absorbs the heat of the material and the conveyor belt 2 to prevent the material from sticking together at high temperature and to cool the conveying environment. The four symmetrically distributed fans 5 on the top of the support frame 1 rotate to accelerate the air flow and assist in heat dissipation. When the height of the guide plate 606 needs to be adjusted, the handle 608 at the top of the lead screw 602 is rotated, causing the lead screw 602 to rotate. This allows the lifting plate 603, which is threadedly connected to the lead screw 602, to slide up and down along the support rod 601 under the limit of the guide rod 604, thereby adjusting the height of the guide plate 606. If the position of the guide plate 606 needs to be finely adjusted, the fixing rod 607 can be loosened, and the guide plate 606 can be slid in the sliding groove 605 before being tightened again. This allows for flexible adjustment of the height and position of the guide plate, effectively guiding airflow, preventing particle scattering, and reducing material loss and environmental pollution.
[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
