Description

Technical Field

[0001] This invention belongs to the field of extruder technology, and in particular relates to a constant temperature water circulation cooling system for extruders. Background Technology

[0002] Prior art with patent application number 202210957812.X discloses a constant temperature water circulation cooling system for an extruder. This system activates a servo motor, and the active pulley drives each driven pulley to rotate via a synchronous belt, causing each cylinder to rotate and conveying the material strip forward. During material conveying, a water pump sequentially pumps cooling water from a constant temperature water tank through a first pipe, a second pipe, a branch pipe, a first water pipe, a second water pipe, an inlet hole, and a bushing into a water supply pipe, then into the cylinder through various through holes. The first and second water outlets, corresponding to the openings of the baffle, spray cooling water onto the material strip, cooling it. Simultaneously, the water streams from the first and second water outlets on a single cylinder converge on the material strip, and the water streams from the first water outlets on adjacent cylinders also converge, providing continuous and comprehensive cooling to the material strip. After being sprayed out, the water streams fall into a water tank under their own weight for recycling. The aforementioned device has the following drawbacks: Since the material strip is placed on an arc-shaped rod within the annular groove, and the groove has a U-shaped cross-section perpendicular to the strip's length, it cannot completely enclose the strip. This results in a temperature difference between the upper and lower surfaces of the strip during cooling, potentially causing deformation due to uneven heating and affecting the cooling effect. Therefore, there is an urgent need to research a constant-temperature water circulation cooling system for extruders to solve these problems. Summary of the Invention

[0003] The present invention provides a constant temperature water circulation cooling system for an extruder, the purpose of which is to solve the technical problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a constant-temperature water circulation cooling system for an extruder, comprising a constant-temperature water mechanism and a frame arranged side by side; a collection box is horizontally fixed to the upper part of the frame; the upper part of the collection box has an open structure; support plates are vertically fixed to two opposite edges of the upper port of the collection box; multiple roller cooling mechanisms are installed side by side between the two support plates; a ring cooling mechanism is installed between two adjacent roller cooling mechanisms; the roller cooling mechanisms, ring cooling mechanisms, collection box, and constant-temperature water mechanism are connected by a constant-temperature water circulation mechanism. The constant-temperature water circulation mechanism delivers constant-temperature water from the constant-temperature water mechanism to the roller cooling mechanism and the ring cooling mechanism respectively, and by conveying the material strip through the roller cooling mechanism and the ring cooling mechanism, a full-coverage cooling and solidification treatment of the material strip is achieved. This not only ensures the uniformity of cooling of the material strip, but also ensures the high recycling rate of cooling water by returning water from the collection box to the constant-temperature water mechanism through the constant-temperature water circulation mechanism.

[0006] As a preferred embodiment of the present invention, the constant temperature water mechanism includes a vertically arranged water storage tank; a pair of vertically distributed partitions are horizontally fixed inside the water storage tank; a first chamber is formed between one partition and the top wall of the water storage tank; a water inlet is provided on one side wall of the first chamber; a second chamber is formed between the other partition and the bottom wall of the water storage tank; a water outlet is provided on one side wall of the second chamber; a plurality of capillary tubes are vertically arranged in the second chamber; the lower end of the capillary tubes extends to the bottom of the second chamber; the upper end of the capillary tubes passes through the two partitions in sequence and extends to the bottom of the first chamber; a receiving opening is provided on the bottom wall of the second chamber; a semiconductor cooling chip is installed in the receiving opening; a conductive plate is horizontally attached to the cold end of the semiconductor cooling chip; the conductive plate is horizontally fixed to the upper surface of the bottom wall of the second chamber; a first cooling fan is horizontally arranged at the hot end of the semiconductor cooling chip; the first cooling fan is installed on the lower surface of the bottom wall of the second chamber. By filling the second chamber with water and using a semiconductor cooling chip to cool the water in the second chamber to the required temperature, the water in the second chamber is then discharged through the outlet. After use, the water flows back to the first chamber through the inlet, and then the water in the first chamber flows into the second chamber through a capillary tube. Since the lower end of the capillary tube extends to the bottom of the second chamber, the cooling water in the second chamber can cool the side wall of the capillary tube, keeping the side wall of the second chamber at a lower temperature. This allows the water flowing from the first chamber into the capillary tube to achieve effective cooling, resulting in a smaller temperature difference between the water flowing out from the lower end of the capillary tube and the cooling water in the second chamber. This ensures that the cooling water temperature in the second chamber is always within the required temperature range, effectively guaranteeing the constant temperature effect of the constant temperature water mechanism, reducing the power consumption of the semiconductor cooling chip, and lowering the overall operating cost of the device.

[0007] In a preferred embodiment of the present invention, a third chamber is formed between the two partitions; the capillary tube is inserted into the third chamber; multiple air outlets are arranged side by side on one opposite side wall of the third chamber; and a second cooling fan is fixedly inserted into the other opposite side wall of the third chamber. The second cooling fan draws outside air into the third chamber, causing the side walls of some of the capillary tubes located within the third chamber to cool down, thereby effectively improving the cooling effect of the capillary tubes on the water flow inside.

[0008] As a preferred embodiment of the present invention, the roller cooling mechanism includes a pair of hollow shafts arranged vertically; both ends of the two hollow shafts are rotatably connected to two support plates; a first gear is fixedly sleeved on the outer periphery of one end of each of the two hollow shafts; the two first gears mesh with each other; multiple sponge rings are arranged side by side on the outer periphery of each of the two hollow shafts; a cooling space for the material strip is formed between the two vertically arranged sponge rings on the two hollow shafts; multiple first water inlets corresponding to the sponge rings are arranged side by side on the circumferential sidewalls of each of the two hollow shafts; the first water inlets are located on the inner side of the sponge rings; the first water inlets are used to spray water from the hollow shaft onto the sponge rings; limit rings are provided on opposite sides of each sponge ring; the limit rings are fixedly sleeved on the outer periphery of the hollow shaft. First, the material strip passes through the cooling space formed between two sponge rings distributed vertically on two hollow shafts. Then, by driving the two hollow shafts to rotate synchronously in opposite directions and simultaneously supplying cooling water into the hollow shafts, the cooling water is discharged from the first water inlet and sprayed onto the sponge rings, thereby forming a water film on the sponge rings. Then, when the material strip passes between the two sponge rings distributed vertically, the surface of the material strip can be fully covered for cooling treatment, thereby effectively improving the cooling efficiency and effect of the material strip.

[0009] As a preferred embodiment of the present invention, the annular cooling mechanism includes a mounting plate vertically fixed between two support plates; the mounting plate is perpendicular to the support plates; a plurality of annular water supply boxes are fixed side-by-side on one side of the mounting plate; the outer circumferential wall of the annular water supply box is provided with water injection holes; the inner circumferential wall of the annular water supply box has an open structure; an annular spray box is coaxially arranged on the inner side of the annular water supply box; the inner side of the annular spray box is fed by a feeding strip; the inner circumferential wall of the annular water supply box and the circumference of the annular spray box are... The outer walls are fitted together; the annular water spray box is rotatably inserted into the mounting plate; a second gear is fixedly sleeved on the outer circumference of one end of the annular water spray box; a water storage chamber is provided inside the annular water spray box; multiple second water delivery holes corresponding to the annular water supply box are opened along the annular direction on the outer circumference of the other end of the annular water spray box; the second water delivery holes are used to transport the cooling water in the annular water supply box to the water storage chamber; multiple water spray holes are axially opened on the inner circumference of the annular water spray box for spraying the cooling water in the water storage chamber onto the surface of the material strip. During the process of the material strip being inserted into the inner side of the annular water spray box, the cooling water in the annular water supply box is transported to the water storage chamber through the second water delivery holes, and the cooling water in the water storage chamber is sprayed onto the surface of the material strip through the water spray holes. At the same time, the multiple second gears realize the synchronous linkage of multiple annular water spray boxes, which can further improve the cooling efficiency and effect of the material strip.

[0010] In a preferred embodiment of the present invention, multiple roller cooling mechanisms and multiple ring cooling mechanisms are connected by a drive mechanism. The drive mechanism includes a servo motor fixed to the lower surface of the bottom wall of the collection tank, multiple first pulleys respectively fixedly sleeved on one end of a hollow shaft of the roller cooling mechanism, and multiple rotating shafts rotatably inserted side-by-side on a support plate. A second pulley is fixedly sleeved on the output shaft of the servo motor. The rotating shaft is parallel to the hollow shaft. A third pulley is fixedly sleeved on one end of the rotating shaft. The multiple third pulleys, second pulleys, and multiple first pulleys are connected by belt drive. A first bevel gear is fixedly sleeved on the other end of the rotating shaft. A second bevel gear meshes with the first bevel gear. The second bevel gear is fixedly sleeved on the outer periphery of one end of an annular spray box of the ring cooling mechanism. The servo motor drives the second pulley to rotate, causing the first pulley to drive the hollow shaft to rotate, and through the third pulley, rotating shaft, first bevel gear, and second bevel gear, driving the annular spray box to rotate, thereby achieving linkage between the roller cooling mechanism and the ring cooling mechanism, effectively improving the overall working efficiency of the device.

[0011] As a preferred embodiment of the present invention, the constant temperature water circulation mechanism includes a water pump, a water supply pipe, and a return water pipe; the water pump is fixed to one side wall of the water storage tank by a bracket; the water inlet of the water pump is connected to the water outlet; one end of the water supply pipe is connected to the water outlet of the water pump; the other end of the water supply pipe is connected in parallel to a plurality of diversion valves corresponding to the roller cooling mechanism and a plurality of water supply pipes corresponding to the ring cooling mechanism; the diversion valve has a pair of drain ends distributed vertically; the two drain ends are respectively rotatably connected to the other ends of the two hollow shafts of the roller cooling mechanism; a plurality of branch pipes are connected in parallel to the water supply pipe; one end of the branch pipe is connected to the water injection hole; one end of the return water pipe is connected to the water inlet; the other end of the return water pipe is connected to the bottom of the collection tank. The constant temperature water in the second chamber is pumped into the water supply pipe by a water pump. The cooling water is then transported to the two hollow shafts of the roller cooling mechanism through the two drain ends of the diversion valve. The cooling water is then transported to the water injection hole of the ring cooling mechanism through multiple branch pipes on the water supply pipe. At the same time, the recycled water in the collection tank is transported to the first chamber through the return water pipe, thereby realizing the recycling of cooling water and effectively improving the cooling water utilization effect.

[0012] The present invention has the following beneficial effects:

[0013] This invention uses a constant temperature water circulation mechanism to transport constant temperature water from the constant temperature water mechanism to the roller cooling mechanism and the ring cooling mechanism respectively. By transporting the material strip through the roller cooling mechanism and the ring cooling mechanism, the material strip is subjected to full-coverage cooling and solidification treatment. This not only ensures the uniformity of cooling of the material strip, but also ensures the recycling rate of cooling water by returning the water in the collection box to the constant temperature water mechanism through the constant temperature water circulation mechanism.

[0014] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1:

[0032] Please see Figure 1 As shown, the present invention is a constant temperature water circulation cooling system for an extruder, comprising a constant temperature water mechanism 1 arranged side by side and a conventional frame 2 in the art; a collection box 3 is horizontally fixed on the upper part of the frame 2; the upper part of the collection box 3 is an open structure; support plates 4 are vertically fixed on two opposite edges of the upper port of the collection box 3; multiple roller cooling mechanisms 5 are arranged side by side between the two support plates 4; a ring cooling mechanism 6 is arranged between two adjacent roller cooling mechanisms 5; the roller cooling mechanism 5, the ring cooling mechanism 6, the collection box 3 and the constant temperature water mechanism 1 are connected by a constant temperature water circulation mechanism 7. In use, the constant temperature water in the constant temperature water mechanism 1 is transported to the roller cooling mechanism 5 and the ring cooling mechanism 6 through the constant temperature water circulation mechanism 7. The material strip is then transported through the roller cooling mechanism 5 and the ring cooling mechanism 6 to achieve full-coverage cooling and solidification treatment. This not only ensures the uniformity of cooling of the material strip, but also allows the water in the collection box 3 to flow back to the constant temperature water mechanism 1 through the constant temperature water circulation mechanism 7, ensuring the recycling rate of the cooling water. Specific Implementation Example 2:

[0034] Based on specific embodiment one, as follows Figures 2-4As shown, the constant temperature water mechanism 1 includes a vertically arranged water storage tank 101; a pair of vertically distributed partitions 102 are horizontally fixed inside the water storage tank 101; a first chamber 103 with a sealed structure is formed between one partition 102 and the top wall of the water storage tank 101; a water inlet 104 is provided on one side wall of the first chamber 103; the water inlet 104 is located at the upper part of the first chamber 103; a second chamber 105 with a sealed structure is formed between the other partition 102 and the bottom wall of the water storage tank 101; a water outlet 106 is provided on one side wall of the second chamber 105; the water outlet 106 is located in the middle of the second chamber 105; a plurality of conventional capillaries 107 are vertically arranged inside the second chamber 105; the lower end of the capillaries 107 extends to the bottom of the second chamber 105; the horizontal position of the lower end of the capillaries 107 is lower than the horizontal position of the water outlet 106; the capillaries 107... The upper end of 07 passes through the two partitions 102 and extends to the bottom of the first chamber 103; the bottom wall of the second chamber 105 has a square-shaped receiving opening; a conventional semiconductor cooling chip 108 is installed in the receiving opening; a conductive plate 109 is horizontally attached to the cold end of the semiconductor cooling chip 108; the conductive plate 109 is disposed above the semiconductor cooling chip 108; the conductive plate 109 is horizontally fixed to the upper surface of the bottom wall of the second chamber 105; the conductive plate 109 can block the upper end of the receiving opening; a conventional first cooling fan 110 is horizontally disposed at the hot end of the semiconductor cooling chip 108; the first cooling fan 110 is disposed below the semiconductor cooling chip 108; the first cooling fan 110 is used to dissipate the heat of the hot end of the semiconductor cooling chip 108; the first cooling fan 110 is installed on the lower surface of the bottom wall of the second chamber 105. In use, the second chamber 105 is filled with water, and the water in the second chamber 105 is cooled to the required temperature by the semiconductor cooling chip 108. Then, the water in the second chamber 105 is discharged through the outlet 106. After use, the water flows back to the first chamber 103 through the inlet 104. The water in the first chamber 103 then flows into the second chamber 105 through the capillary tube 107. Since the lower end of the capillary tube 107 extends to the bottom of the second chamber 105, the cooling water in the second chamber 105 can cool the side walls of the capillary tube 107. The cooling process causes the sidewalls of the second chamber 105 to be at a lower temperature, thereby enabling the water flowing from the first chamber 103 into the capillary tube 107 to achieve an effective cooling. This also ensures that the water flowing out from the lower end of the capillary tube 107 has a smaller temperature difference with the cooling water in the second chamber 105, thus guaranteeing that the cooling water temperature in the second chamber 105 remains within the required temperature range. This not only effectively ensures the constant temperature effect of the constant temperature water mechanism 1, but also reduces the power consumption of the semiconductor cooling chip 108 and lowers the overall operating cost of the device.

[0035] Among them, such as Figures 2-3 and Figure 5As shown, a third chamber 111 is formed between the two partitions 102; a capillary tube 107 is inserted into the third chamber 111; multiple strip-shaped air outlets 112 are arranged side by side on one opposite side wall of the third chamber 111; a conventional second cooling fan 113 is fixedly inserted into the other opposite side wall of the third chamber 111; the second cooling fan 113 is used to draw outside air into the third chamber 111 to cool down a portion of the capillary tube 107 located in the third chamber 111. In use, the second cooling fan 113 draws outside air into the third chamber 111, causing the side walls of the capillary tube 107 located in the third chamber 111 to cool down, thereby effectively improving the cooling effect of the capillary tube 107 on the water flow inside.

In use, the material strip is first passed through the cooling space formed between two vertically distributed sponge rings 503 on two hollow shafts 501. Then, the two hollow shafts 501 are driven to rotate synchronously in opposite directions, and cooling water is simultaneously delivered into the hollow shafts 501. The cooling water is discharged from the first water inlet 504 and sprayed onto the sponge rings 503, thereby forming a water film on the sponge rings 503. When the material strip passes between the two vertically distributed sponge rings 503, the surface of the material strip can be fully covered by cooling treatment, thereby effectively improving the cooling efficiency and effect of the material strip.
