A composite high modulus agent cooling device and a granulator

Abstract

This invention discloses a cooling device and granulator for a composite high-modulus agent, comprising a water tank and a U-shaped mounting frame. A guide roller is rotatably connected to the mounting frame, and one end of the mounting frame is hinged to the inner wall of the water tank. A connecting rod is vertically mounted on the upper side of the mounting frame, and an operating rod perpendicular to the connecting rod is connected to the connecting rod. When the mounting frame is rotated to a horizontal position, the operating rod abuts against the upper side of the water tank. The mounting frame can rotate upwards to lean against the side wall of the water tank. The mounting frame can rotate up and down. Before lifting the linear composite high-modulus agent material from the extruder, the mounting frame can be rotated upwards to lean against the side wall of the water tank, and then the composite high-modulus agent material can be pulled forward using a tool. The composite high-modulus agent material can move forward at a position slightly below the liquid surface. After the composite high-modulus agent material passes the guide roller, the previously upward-rotated guide roller can rotate downwards to a horizontal position, pressing down on the linear composite high-modulus agent material and guiding it forward.

Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, specifically to a composite high modulus agent cooling device and granulator. Background Technology

[0002] Granulation is a crucial step in the production of composite high modulus agents. Currently, the common production process for composite high modulus agent granules is as follows: first, the uniformly mixed material is extruded into a linear shape using an extruder; then, the linear material is cooled in a water tank; after it has cooled and solidified, it is granulated; finally, the granules are sieved to obtain composite high modulus agent granules that meet the size requirements.

[0003] In this process, when the linear material freshly extruded from the extruder enters the cooling tank, it is in a soft and unformed state, requiring manual lifting and traction to guide it along the entire production line to the pelletizing station. Simultaneously, guide rollers are installed below the liquid surface in the tank, and the linear material must pass under these rollers to ensure stable movement during cooling. However, this method has drawbacks: the operator's hands need to be immersed in the cooling liquid (the guide rollers are located at the bottom of the tank, requiring the hand to reach quite deep), and the temperature of the cooling liquid is usually low, causing discomfort; furthermore, some cooling liquids contain added chemicals that are unsuitable for direct contact. Utility Model Content

[0004] In view of the problems pointed out in the background art, this utility model proposes a composite high modulus agent cooling device and granulator to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A composite high modulus agent cooling device includes a water tank and a U-shaped mounting frame. A guide roller is rotatably connected to the mounting frame. One end of the mounting frame is hinged to the inner wall of the water tank, allowing the mounting frame to rotate up and down around the hinge axis. A connecting rod is vertically provided on the upper side of the mounting frame, and an operating rod perpendicular to the connecting rod is connected to the connecting rod. When the mounting frame is rotated to a horizontal position, the operating rod abuts against the upper side of the water tank. The mounting frame can be rotated upwards to lean against the side wall of the water tank.

[0007] The present invention is further provided that the side wall of the water tank is provided with a hinge part, and the hinge part is provided with a hinge shaft that is rotatably connected to the mounting frame.

[0008] The present invention is further configured such that the hinge shaft is spaced apart from the side wall of the water tank.

[0009] The present invention is further configured such that the mounting frame includes a crossbeam, and two fixed arms are provided on the lower side of the crossbeam, and the two ends of the guide roller are respectively rotatably connected to the two fixed arms.

[0010] The present invention is further configured such that the lower end of the fixed arm is positioned below the lower side of the guide roller.

[0011] The present invention is further configured to include a reinforcing rod connecting the operating lever and the mounting bracket.

[0012] The present invention is further configured such that the mounting bracket, connecting rod, and operating lever are integrated into one unit.

[0013] A composite high modulus agent granulator includes a screw extruder, a pelletizing device, and a vibrating screening device arranged in sequence, with the cooling device disposed between the extruder and the pelletizing device.

[0014] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0015] The composite high modulus agent cooling device and granulator provided by this utility model have a mounting frame that can rotate up and down. Before lifting the linear composite high modulus agent material from the extruder, the mounting frame can be rotated upwards to lean against the side wall of the water tank. Then, the composite high modulus agent material is pulled forward by a tool. The composite high modulus agent material can move forward at a position slightly below the liquid surface. After the composite high modulus agent material passes the guide roller, the guide roller, which was rotated upwards beforehand, can be rotated downwards to a horizontal state to press down the linear composite high modulus agent material and guide it to move forward.

[0016] The guide roller of this application can rotate up and down with the help of the mounting frame, which makes it convenient to lift and lower the mounting frame and the guide roller. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] For reference as follows Figures 1-3 The present invention will be described as follows:

[0024] Example: A composite high modulus agent cooling device includes a water tank 1 and a U-shaped mounting frame. The water tank 1 serves as a carrier for the cooling medium and has an upward-opening design, providing space for cooling linear materials.

[0025] The U-shaped mounting bracket serves as the mounting carrier for the guide roller 3, and its rotational connection method directly determines the position adjustment capability of the guide roller 3.

[0026] The mounting frame is rotatably connected to the guide roller 3. The mounting frame is located at the bottom of the inner side of the water tank 1. One end of the mounting frame is hinged to the inner side wall of the water tank 1, so that the mounting frame can rotate up and down around the hinge axis 4. This provides a basis for the mounting frame to rotate up and down, so that the guide roller 3 can be disengaged from or enter the working position below the coolant surface.

[0027] The rotatable connection between the guide roller 3 and the mounting frame ensures that it can rotate synchronously with the material movement when guiding linear materials, thereby reducing frictional damage to the material surface.

[0028] A connecting rod 5 is vertically mounted on the upper side of the mounting bracket, and an operating lever 6 is connected to the connecting rod 5 perpendicular to it; the operator can control the rotation state of the mounting bracket by manipulating the operating lever 6 without directly contacting the cooling liquid.

[0029] When the mounting bracket is rotated to the horizontal position, the operating lever 6 abuts against the upper side of the water tank 1 (equivalent to the operating lever 6 resting on the upper end of the water tank 1, keeping the mounting bracket and guide roller 3 in a horizontal working state); the mounting bracket can be rotated upwards to lean against the side wall of the water tank 1, so that the mounting bracket can be stably stopped in the upward rotating open state.

[0030] During operation, the two key states of the mounting frame are stably maintained through structural design: When the mounting frame is rotated to the horizontal state, the operating lever 6 abuts against the upper side of the water tank 1, using the edge of the water tank 1 as a support point, so that the mounting frame and guide roller 3 are kept in the working position below the liquid surface. At this time, the guide roller 3 can support the linear material from below, ensuring that it travels in the cooling medium according to the preset path; when the material traction operation is required, the operating lever 6 is lifted upward, and the mounting frame rotates upward around the hinge axis 4 until it leans against the side wall of the water tank 1. In this state, the guide roller 3 is completely separated from the cooling liquid surface area, providing unobstructed space for the initial traction of the linear material.

[0031] The advantage of this structure lies in the optimized operation process: Traditional manual traction requires reaching under the liquid surface to maneuver around the guide roller 3. This device, however, lifts the mounting frame, allowing linear materials to be pulled forward directly at a position slightly below the liquid surface. Once the material's tip has passed the area where the guide roller 3 is located, the mounting frame is reset to a horizontal position using the operating lever 6, and the guide roller 3 naturally presses down under the material, thus providing guidance. During this process, the operator does not need to contact the cooling liquid; the position of the guide roller 3 can be switched solely using the operating lever 6. This avoids harm to the operator from the low-temperature liquid and ensures ease of operation.

[0032] Meanwhile, the rotation angle of the mounting frame is limited by the contact position between the operating lever 6 and the water tank 1, ensuring that the working position of the guide roller 3 is consistent after each reset, reducing the material path deviation caused by differences in manual operation, which is conducive to ensuring the shape stability of linear materials after cooling, and thus improving the product consistency of subsequent pelletizing processes.

[0033] A hinge 7 is provided on the side wall of the water tank 1, serving as the connection node between the mounting frame and the water tank 1. The hinge 7 has a hinge shaft 4 that is rotatably connected to the mounting frame. The hinge shaft 4 is spaced apart from the side wall of the water tank 1, providing necessary space for the rotation of the mounting frame: when the mounting frame rotates upwards, since the hinge shaft 4 does not directly contact the side wall, the non-hinged end of the mounting frame can smoothly approach the side wall and eventually lean against the side wall of the water tank 1. This spaced design, combined with the weight distribution of the mounting frame itself, allows the mounting frame to achieve balance between the supporting force of the side wall and its own weight in the leaning state, maintaining stability without additional fasteners. This ensures that during the initial material traction stage, the guide roller 3 remains detached from the liquid surface, providing a stable and unobstructed space for operation.

[0034] The mounting frame includes a crossbeam 8, with two fixed arms 9 on its lower side. The guide roller 3 is rotatably connected to both fixed arms 9 at both ends, forming a stable frame structure. The crossbeam 8, as the main supporting component of the mounting frame, serves to connect the link 5 and transmit operating forces.

[0035] The lower end of the fixed arm 9 is positioned below the lower side of the guide roller 3. This dimensional design provides it with a clear limiting function: when linear material is conveyed below the guide roller 3, the lower ends of the fixed arms 9 on both sides form a barrier along the axial direction of the guide roller 3. Since the material may shift axially during the cooling process due to fluctuations in conveying speed or external interference, the lower ends of the fixed arms 9 can directly block the material from moving towards both ends, effectively preventing the material from detaching from both axial ends of the guide roller 3, ensuring that the material always travels stably along the preset path, and further improving the reliability of the cooling process.

[0036] It also includes a reinforcing rod 10 that connects the operating lever 6 and the mounting bracket, thus strengthening the overall structural strength.

[0037] The mounting frame, connecting rod 5, and operating lever 6 are integrated into one unit, eliminating connection gaps and assembly errors between components. This design makes force transmission more direct and efficient: the force applied by the operator to the operating lever 6 is transmitted to the mounting frame without loss through the continuous solid structure, ensuring precise rotational response of the mounting frame; at the same time, the integrated structure avoids relative displacement of components due to loose assembly, ensuring that the contact position between the operating lever 6 and the upper side of the water tank 1 is always consistent when the mounting frame is in a horizontal working state, thereby ensuring the stable working position of the guide roller 3 and providing consistent guiding conditions for material cooling.

[0038] A composite high modulus agent granulator includes a screw extruder 11, a pelletizing device 12, and a vibrating screening device 13 arranged in sequence, with the cooling device disposed between the screw extruder 11 and the pelletizing device 12.

[0039] The compound high modulus agent granulator forms a complete granulation process through the sequential connection of a screw extruder 11, a cooling device, a pelletizing device 12, and a vibrating screening device 13. The synergistic effect and structural correlation of each device are analyzed as follows:

[0040] From an overall layout perspective, the screw extruder 11, as the initial stage of material shaping, has its discharge end corresponding to the feed side of the cooling device, ensuring that the linear material extruded through the extruder die can directly enter the water tank 1 of the cooling device. The cooling device is positioned between the screw extruder 11 and the pelletizing device 12, with its water tank 1 discharge end aligned with the feed inlet of the pelletizing device 12, allowing the cooled and shaped linear material to directly enter the pelletizing device 12 for cutting. The discharge direction of the pelletizing device 12 is opposite to the feed area of ​​the vibrating screening device 13. The cut particles fall into the vibrating screening device 13 by gravity or conveying components, completing the final grading and screening.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
