Description

Technical Field

[0001] This utility model relates to the field of extrusion press technology, and more specifically, to an extrusion press cooling structure. Background Technology

[0002] The extruder has undergone tremendous changes in just over a century, evolving from a few mega-newtons of manually operated hydraulic presses to two hundred mega-newtons of fully automatic oil presses. The variety of extruders has also greatly increased. The capacity and quantity of extruders reflect a company's production technology level. A country's capacity, quantity, production capacity, and equipment level of extruders reflect its level of industrial development.

[0003] In industries such as plastics, rubber, and metal processing, extruders are widely used key pieces of equipment used to extrude raw materials into shapes through heating and pressurization. During operation, the screw, barrel, and other core components of an extruder are subjected to high friction and high temperatures for extended periods, causing a rapid rise in equipment temperature. Excessively high temperatures not only affect product quality (such as material degradation and dimensional instability) but also accelerate equipment wear, shorten its service life, and even pose safety hazards. Utility Model Content

[0004] Therefore, in order to solve the problem that excessively high temperatures during prolonged extrusion operation can affect product quality, this utility model provides an extrusion cooling structure, the specific technical solution of which is as follows:

[0005] An extruder cooling structure includes a spraying mechanism and a blower mechanism. The spraying mechanism includes a sliding assembly and a spraying assembly. The spraying assembly includes a pressurizing component, a spraying component, and a positioning seat mounted on the sliding assembly. One end of the pressurizing component is mounted on the positioning seat, and the other end of the pressurizing component is connected to the spraying component. The spraying component is provided with multiple nozzles, and each nozzle is provided with an anti-clogging device. The blower mechanism includes a support frame and a blower assembly mounted on the support frame. The blower assembly includes multiple blowers arranged side by side at intervals, and the air outlet direction of the blowers is downward.

[0006] The aforementioned extruder cooling structure incorporates a sliding component to facilitate adjustment of the spray assembly's position, allowing the nozzles to better target overheated areas of the extruder for effective cooling. An anti-clogging device scrapes and cleans the inside of the nozzles, preventing water stains and dirt buildup that could clog them. Multiple blowers, utilizing forced airflow, rapidly dissipate heat, preventing overheating and ensuring stable long-term operation. The coordinated operation of the spray and blower assemblies enhances cooling efficiency and resolves the issue of excessively high temperatures affecting product quality during prolonged extruder operation.

[0007] Furthermore, the sliding assembly includes a mounting platform, a first sliding rail, a second sliding rail, and a sliding seat. The mounting platform has an inclined groove, and the first sliding rail and the second sliding rail are respectively provided on the upper and lower groove walls. The sliding seat is slidably mounted on the first sliding rail and the second sliding rail, and the positioning seat is detachably fixed on the sliding seat.

[0008] Furthermore, the sliding assembly also includes a drive rail and a drive component. The drive rail is disposed on the top of the mounting platform, and the sliding seat has a slider adapted to the drive rail. The drive component is mounted on the sliding seat and is used to drive the slider to slide on the drive rail.

[0009] Furthermore, limiting components are installed on both ends of the inclined groove, and buffer protrusions are provided on the limiting components. The two buffer protrusions are arranged facing each other, and a sliding space is formed between the two buffer protrusions for the sliding seat to move.

[0010] Furthermore, the pressurizing component is a water pump.

[0011] Furthermore, the spraying component includes a connecting pipe, a liquid storage tank, and spray pipes. One end of the connecting pipe is sleeved on the pressurizing component, and the other end of the connecting pipe is inserted into the liquid storage tank. Multiple spray pipes are spaced apart on the liquid storage pipe, and each spray pipe is fitted with a nozzle.

[0012] Furthermore, a spray cavity is formed inside the nozzle; the anti-clogging device includes an annular frame fixed to the inner wall of the spray cavity, a horizontal plate fixed to the annular frame, an anti-clogging fan blade rotatably connected to the horizontal plate, and a curved part connected to and rotating synchronously with the anti-clogging fan blade, wherein the rotation axis of the anti-clogging fan blade is parallel to the axial direction of the nozzle.

[0013] Furthermore, the surface of the curved portion is provided with a cleaning brush, which is in contact with the inner wall of the spray cavity.

[0014] Furthermore, the blower is provided with a blower fan, and the blower fan is provided with multiple blower blades and multiple axial blades.

[0015] Furthermore, the axial blade is disposed between every two blower blades, and a gap is formed between the axial blade and the blower blade. The axial blade is arc-shaped, and the orientation of the end of the axial blade is opposite to the direction of the twist of the outer end of the blower blade. Attached Figure Description

[0027] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, an extruder cooling structure in one embodiment of the present invention includes a spraying mechanism and a blower mechanism. The spraying mechanism includes a sliding component 1 and a spraying component 2. The spraying component 2 includes a pressurizing component 21, a spraying component 22, and a positioning seat 23 mounted on the sliding component 1. One end of the pressurizing component 21 is mounted on the positioning seat 23, and the other end of the pressurizing component 21 is connected to the spraying component 22. The spraying component 22 is provided with a plurality of nozzles 221, and an anti-clogging device 4 is provided inside the nozzles 221. The blower mechanism includes a support frame 51 and a blower component 5 mounted on the support frame 51. The blower component 5 includes a plurality of blower components 52 arranged side by side at intervals, and the air outlet direction of the blower components 52 is downward.

[0029] The aforementioned extruder cooling structure, by incorporating a sliding component 1, facilitates the adjustment of the spray component 2's position, allowing the nozzles 221 to better target the overheated parts of the extruder for cooling. An anti-clogging device 4 scrapes and cleans the inside of the nozzles 221, removing water stains and dirt and preventing clogging. Multiple blowers 52 rapidly dissipate heat through forced airflow, preventing overheating and ensuring stable long-term operation. The coordination between the spray component 2 and the blower component 5 improves cooling efficiency and solves the problem of excessively high temperatures affecting product quality during prolonged extruder operation.

[0030] like Figure 1 and Figure 2As shown, in one embodiment, the sliding assembly 1 includes a mounting platform 11, a first sliding rail 12, a second sliding rail 13, and a sliding seat 14. The mounting platform 11 has an inclined groove 111. The first sliding rail 12 and the second sliding rail 13 are respectively provided on the upper and lower groove walls of the inclined groove 111. The sliding seat 14 is slidably mounted on the first sliding rail 12 and the second sliding rail 13 respectively. The positioning seat 23 is detachably fixed on the sliding seat 14.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the sliding assembly 1 further includes a drive rail 15 and a drive member 16. The drive rail 15 is disposed on the top of the mounting platform 11, and the sliding seat 14 is provided with a slider adapted to the drive rail 15. The drive member 16 is mounted on the sliding seat 14 and is used to drive the slider to slide on the drive rail 15.

[0032] Preferably, the driving component 16 is a drive motor. The use of a drive motor to control the sliding of the sliding seat 14 on the drive guide rail 15 is existing technology and will not be elaborated upon here.

[0033] Specifically, both the sliding track and the drive guide rail 15 are arranged in a horizontal direction.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, limiting members 17 are installed at both ends of the inclined groove 111. Each limiting member 17 has a buffer protrusion 171, which faces each other, forming a sliding space between them for the sliding seat 14 to move. Thus, by providing the buffer protrusion 171, the buffer block can effectively absorb and disperse the impact force, preventing damage to the sliding seat 14 when it impacts the limiting member 17. The sliding space also limits the movement of the sliding seat 14, preventing it from sliding out of the mounting platform 11 during position adjustment and thus preventing it from derailing and affecting subsequent cooling operations.

[0035] Preferably, the pressurizing component 21 is a water pump. This is prior art, and its specific technical features and effects will not be described in detail.

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, the spray component 22 includes a connecting pipe 222, a liquid storage tank 223, and spray nozzles 224. One end of the connecting pipe 222 is sleeved on the pressurizing component 21, and the other end of the connecting pipe 222 is inserted into the liquid storage tank 223. Multiple spray nozzles 224 are spaced apart on the liquid storage pipe, and each spray nozzle 224 is fitted with a nozzle 221. The pressurizing component 21 is used to increase the pressure of the cooling liquid in the liquid storage tank 223 by pressurizing it, so that it can be sprayed out from the nozzles 221.

[0037] like Figure 4 As shown, in one embodiment, a spray cavity 2211 is formed inside the nozzle 221; the anti-clogging device 4 includes an annular frame 41 fixed to the inner wall of the spray cavity 2211, a horizontal plate 42 fixed to the annular frame 41, an anti-clogging fan blade 43 rotatably connected to the horizontal plate 42, and a curved part 44 connected to and rotating synchronously with the anti-clogging fan blade 43. The rotation axis of the anti-clogging fan blade 43 is parallel to the axial direction of the nozzle 221. The anti-clogging fan blade 43 uses the pressure of the nozzle 221 when spraying water to achieve self-rotation, automatically cleaning the inner wall of the spray cavity 2211.

[0038] like Figure 4 As shown, in one embodiment, the surface of the curved portion 44 is provided with a cleaning brush 45, which is in contact with the inner wall of the spray cavity 2211. This increases the friction between the curved portion 44 and the spray cavity 2211. Through the contact between the cleaning brush 45 and the inner wall of the spray cavity 2211, the inside of the nozzle 221 can be cleaned, thereby cleaning the water stains and dirt adhering to the inner wall of the spray cavity 2211. This prevents the accumulation and sedimentation of water stains and dirt from clogging the nozzle 221, thereby improving the working efficiency of the nozzle 221 during the cooling process.

[0039] like Figure 5 and Figure 6 As shown, in one embodiment, a blower fan 521 is provided inside the blower 52, and the blower fan 521 is provided with a plurality of blower blades 5211 and a plurality of axial blades 5212.

[0040] like Figure 6 As shown, in one embodiment, axial blades 5212 are disposed between every two blower blades 5211, and a gap is formed between the axial blades 5212 and the blower blades 5211. The axial blades 5212 are arc-shaped, and the direction of the ends of the axial blades 5212 is opposite to the direction of the twist of the outer ends of the blower blades 5211. The rotation of the blower blades 5211 and the axial blades 5212 drives the surrounding airflow. The blower blades 5211 generate airflow in a 180° direction (consistent with the direction of the incoming airflow), and the axial blades 5212 can generate airflow in a 90° direction (perpendicular to the direction of the incoming airflow). The air pressure and air volume are relatively large, meeting different production needs and greatly enhancing the cooling effect.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
