Description

Technical Field

[0001] The present invention relates to the field of plastic product cooling devices, and particularly to a cooling device for plastic product production. Background Art

[0002] In the production process of plastic products, the design of the cooling system is crucial for ensuring the quality of the products. In the plastic extrusion molding process, the coolant plays a vital role. It can quickly and effectively reduce the temperature of the plastic, enabling it to maintain a certain shape during the curing process. However, with the continuous improvement of production requirements, the deficiencies of traditional cooling devices have gradually emerged;

[0003] Existing cooling devices usually adopt a single coolant circulation system, and heat exchange is carried out by the contact between the coolant and the plastic. These devices have relatively simple structures, and the coolant circulates through the pipes to absorb the heat during the plastic processing. However, in practical applications, this cooling method has some obvious disadvantages. First, due to the uneven flow and temperature distribution of the coolant, there is often a large temperature difference at both ends of the pipe, resulting in uneven cooling effects. Second, the existing devices lack an efficient heat dissipation mechanism, which causes the temperature of the coolant to gradually increase during long-term operation, thereby reducing the cooling efficiency and even possibly affecting the final quality of the plastic products;

[0004] Therefore, the problem of uneven heat dissipation of the coolant cannot be effectively solved in the prior art, nor can the temperature consistency at both ends of the coolant be ensured, resulting in unstable temperature control during the cooling process and affecting the stability of the plastic extrusion molding process and the controllability of the product quality.

[0005] Chinese Patent Publication No. CN218227398U discloses a cooling device for plastic product production, which solves the problem that in the prior art, the connecting cylinder is located at the center of the box body, and when the granular plastic particles flow inside the box body, the density is relatively large, resulting in a small contact area between the cold air passing through the connecting cylinder and then coming out from the air outlet pipe and the plastic particles, and it is impossible to uniformly and effectively cool and lower the temperature of the plastic particles inside the box body, and the efficiency is relatively low during use. A cooling device for plastic product production includes a bottom plate, and a feeding pipe, a material box, a delivery pump and a plurality of support frames for supporting the feeding pipe are arranged on the surface of the bottom plate. The above patent document cools down by introducing cold water into the stirring pipe, and at the same time uses the stirring pipe to stir the plastic particles inside the feeding pipe, so that the movable stirring pipe can contact the plastic particles as evenly as possible, thereby further improving the cooling efficiency and facilitating use.

[0006] During the use of the device in the above-mentioned patent document, although it can play a role in cooling during plastic production, in the actual use process, it cannot effectively solve the problem of uneven heat dissipation of the coolant, nor can it ensure the temperature consistency at both ends of the coolant, resulting in unstable temperature control during the cooling process, affecting the stability of the plastic extrusion molding process and the controllability of product quality.

Specific implementation mode

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0031] Example 1, as Figure 1 and Figure 2 shown, a cooling device for plastic product production includes a bottom plate 1. A operating table 2 is fixedly connected to the middle rear side of the upper end of the bottom plate 1. A servo motor 3 is fixedly connected to the rear side of the upper end of the operating table 2. A differential 4 is fixedly connected to the middle rear side of the upper end of the operating table 2. The differential 4 is located in front of the servo motor 3. The output end of the servo motor 3 is fixedly connected to the input end of the differential 4 through a coupling. A fixed table 5 is fixedly connected to the rear side of the upper end of the operating table 2. The fixed table 5 is located in front of the differential 4. The inner surface of the fixed table 5 is fixedly connected with a feeding pipe 6. The rear part of the upper side of the outer surface of the feeding pipe 6 is fixedly connected with a feeding box 7. The front side wall of the inner surface of the feeding pipe 6 is rotatably connected with a screw extrusion rod 8. The rear end of the screw extrusion rod 8 is fixedly connected to the output end of the differential 4. A driving assembly 9 is fixedly installed on the front right side of the upper end of the operating table 2. A cooling assembly 10 is fixedly installed on the middle front side of the upper end of the bottom plate 1. By setting the cooling assembly 10, when the plastic product is extruded and formed, the plastic product in the inner cavity of the extrusion sub-pipe 100 can be preliminarily cooled, and the temperature of the coolant in the hollow pipe 102 can be kept the same at the front end and the rear end, avoiding the inconsistent temperature of the coolant at both ends of the hollow pipe 102 during the long-term extrusion and forming process, resulting in ineffective plastic forming. And the cooling assembly 10 can also dissipate heat from the coolant being cooled, so as to ensure that the coolant in the hollow pipe 102 can fully cool the extruded plastic parts;

[0032] At the front part of the upper end of the bottom plate 1, a solidifying component 11 is fixedly installed. The solidifying component 11 is located on the front side of the cooling component 10. By setting the solidifying component 11, during the use process, it cooperates with the cooling component 10 to intermittently cut the preliminarily cooled plastic parts. And after cutting the plastic parts, they can be uniformly collected, and the collected plastic parts are subjected to water-cooling treatment, thereby improving the cooling efficiency of the plastic parts during production and thus increasing the yield rate of the plastic parts.

[0033] The operation table 2, servo motor 3, differential 4, fixed table 5, feeding pipe 6, feeding box 7 and screw extrusion rod 8 mentioned above together form an extruder in the prior art. During its operation, by starting the servo motor 3, power is generated at the output end of the servo motor 3. Subsequently, the differential 4 increases the torque and reduces the speed, and transmits this power to the rear end of the screw extrusion rod 8, so that the screw extrusion rod 8 can extrude and process the materials poured into the feeding box 7. The fixed table 5 plays a role in limiting and fixing the feeding pipe 6, and the subsequently extruded plastic will be transported through the feeding pipe 6 into the extrusion sub-pipe 100.

[0034] Therefore, the operation table 2, servo motor 3, differential 4, fixed table 5, feeding pipe 6, feeding box 7 and screw extrusion rod 8 mentioned above are all conventional settings in the prior art. In this solution, it only needs to meet the extrusion and processing requirements of the plastic parts. The specific installation method, circuit connection method and control method are all conventional designs, so this solution will not elaborate on them in detail.

[0035] Embodiment 2. On the basis of Embodiment 1, this embodiment aims to uniformly dissipate the heat of the extruded plastic, that is, to ensure that the temperature of the coolant always remains consistent.

[0036] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 , the driving component 9 includes a mounting table 91 fixedly connected to the upper right side, a mounting table 92 fixedly connected to the front right side of the mounting table 91, a mounting table 93 fixedly connected to the upper right side of the mounting table 91, a motor 94 fixedly connected to the upper end of the mounting table 93, a pulley 95 rotatably connected to the upper side of the middle part of the rear end of the mounting table 92, and the middle part of the rear end of the pulley 95 is fixedly connected to the output end of the motor 94 through a coupling.

[0037] Further, the cooling component 10 includes two fixed hollow rods 101 symmetrically distributed front and back. The lower ends of the two fixed hollow rods 101 are fixedly connected to the front part of the upper end of the bottom plate 1. A hollow tube 102 is fixedly connected to the inner surfaces of the two fixed hollow rods 101. An installation groove 103 penetrating through its rear end is formed in the middle of the front end of the hollow tube 102. A rotating ring 104 is rotatably connected to the front side wall of the inner surface of the hollow tube 102. A rotating groove 1000 is formed in the front side wall of the inner surface of the hollow tube 102. An engagement ring 105 is rotatably connected to the inner surface of the rotating groove 1000. The front end of the engagement ring 105 is fixedly connected to the rear end of the rotating ring 104. A second pulley 106 is fixedly connected to the rear end of the engagement ring 105. A plurality of annular heat dissipation fins 107 are fixedly connected to both the front side and the rear side of the outer surface of the hollow tube 102 in a linear array. A drain pipe 108 is fixedly connected to the middle of the lower side of the outer surface of the hollow tube 102. The drain pipe 108 communicates with the inner cavity of the hollow tube 102. A threaded bolt is threadedly connected to the inner surface of the drain pipe 108. A stirring component 109 is fixedly installed at the front end of the rotating ring 104. The front end of the feed pipe 6 is fixedly connected to an extrusion sub-pipe 100. The outer surface of the extrusion sub-pipe 100 fits with the inner surface of the installation groove 103.

[0038] Further, a transmission belt 96 is wound around the outer surfaces of the second pulley 106 and the first pulley 95.

[0039] Further, the stirring component 109 includes a spiral plate 1091 fixedly connected to the front end of the rotating ring 104. A plurality of hollow columns 1092 are fixedly connected to the outer surface of the spiral plate 1091 in a spiral array. A plurality of through holes 1093 communicating with their inner cavities are formed in the outer surfaces of the plurality of hollow columns 1092.

[0040] Further, both the spiral plate 1091 and the plurality of hollow columns 1092 are made of copper.

[0041] As can be seen from the above embodiments, the extruded plastic can be spirally extruded from the feed pipe 6 into the inner cavity of the extrusion sub-pipe 100 by the spiral extrusion rod 8. In this process, by starting the first motor 94, the output end of the first motor 94 can drive the first pulley 95 fixedly connected thereto to rotate through a coupling. A transmission belt 96 is wound around the outer surfaces of the first pulley 95 and the second pulley 106. Therefore, when the first pulley 95 rotates, the second pulley 106 also rotates accordingly;

[0042] The second pulley 106 is fixedly connected to the engagement ring 105, and the front end of the engagement ring 105 is fixedly connected to the rotating ring 104. Therefore, while the engagement ring 105 can rotate in the inner cavity of the rotating groove 1000, it can drive the rotating ring 104 to rotate. When the rotating ring 104 rotates, the spiral plate 1091 fixedly connected thereto can rotate accordingly;

[0043] When the spiral plate 1091 rotates, due to its spiral distribution, during the rotation of the spiral plate 1091 along with the rotating ring 104, the coolant in the inner cavity of the hollow tube 102 can be spirally agitated. The spiral agitation will generate a secondary circulation effect, break the thermal boundary layer, increase the temperature gradient between the tube wall and the fluid, and the spiral flow rotates with heat like a tornado;

[0044] Moreover, when the spiral plate 1091 rotates spirally along with the rotating ring 104, a number of hollow columns 1092 fixedly connected to the outer surface of the spiral plate 1091 in a spiral arrangement can stir the coolant in the hollow tube 102 during the spiral rotation. And during the stirring process, since the coolant in the hollow tube 102 does not completely fill the inner cavity of the hollow tube 102, when a number of hollow columns 1092 rotate spirally along with the spiral plate 1091, a number of through holes 1093 opened on their outer surfaces can stir out dense bubbles in the coolant. When each bubble bursts, a micro shock wave will be generated, just like countless small hammers knocking on the tube wall, "shaking" off the attached heat, which can improve the local heat transfer efficiency;

[0045] Meanwhile, a number of annular heat dissipation fins 107 fixedly connected to the front and rear of the outer surface of the hollow tube 102 can further dissipate the heat of the cooling in the inner cavity of the hollow tube 102;

[0046] During this process, through the spiral agitation and the generation of dense bubbles during the stirring process, while keeping the temperature of the coolant in the hollow tube 102 consistent, the heat exchange efficiency of the extrusion sub-tube 100 can be improved, and further the cooling effect on the plastic in the inner cavity of the extrusion sub-tube 100 can be improved;

[0047] And in this solution, both the spiral plate 1091 and a number of hollow columns 1092 are made of copper material, and the copper material has good heat dissipation efficiency, so the overall cooling and heat dissipation efficiency can be further improved;

[0048] Finally, the cooled plastic part will be extruded from the front end of the extrusion sub-tube 100, and the extruded plastic part is in a semi-solidified state for subsequent cutting and processing;

[0049] During long-term processing, when the coolant needs to be replaced, only need to rotate and open the threaded bolt threadedly connected to the inner cavity of the drain pipe 108 to pour out the coolant, and then inject new coolant into the inner cavity of the hollow tube 102 from the drain pipe 108, without completely filling it.

[0050] The specific method of injecting the coolant is a conventional technical means in the prior art, so this solution will not elaborate on it in detail.

[0051] A number of the above annular heat dissipation fins 107 are all conventional settings in the prior art. In this solution, it only needs to meet the requirement of dissipating heat from the outer surface of the hollow tube 102. Therefore, this solution will not elaborate on it in detail.

[0052] Embodiment 3. On the basis of Embodiment 2, this embodiment aims to achieve batch cutting of the extruded plastic and cooling and solidification of the cut plastic.

[0053] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , the solidification assembly 11 includes a water holding box 111 fixedly connected to the front part of the upper end of the bottom plate 1. A drain port 112 penetrating its inner cavity is opened on the lower side of the middle part of the right end of the water holding box 111. A rubber plug 113 is threadedly connected to the inner surface of the drain port 112. An inclined plate 114 is fixedly connected to the rear side of the upper end of the horizontal part of the water holding box 111. Two symmetrically distributed clamping and cutting assemblies 115 are fixedly installed at the rear end of the water holding box 111.

[0054] Furthermore, the two clamping and cutting assemblies 115 include two connecting plates 1151 fixedly connected to the right side of the rear end of the water holding box 111. A rectangular plate 1152 is fixedly connected to the upper part of the front ends of the two connecting plates 1151. A connecting platform 1153 is fixedly connected to the middle part of the rear ends of the two connecting plates 1151. A second motor 1154 is fixedly connected to the middle part of the upper end of the connecting platform 1153. A disc 1155 is rotatably connected to the middle part of the front end of the rectangular plate 1152. The rear end of the disc 1155 is fixedly connected to the output end of the second motor 1154 through a coupling. An eccentric part of the front end of the disc 1155 is rotatably connected to a cylinder 1156. A hollow elliptical plate 1157 is slidably connected to the outer surface of the cylinder 1156. Push rods 1158 are fixedly connected to both the left end and the right end of the hollow elliptical plate 1157. Limiting clamping plates 1159 are fixedly connected to both the left side and the right side of the middle part of the front end of the rectangular plate 1152. The two push rods 1158 are respectively slidably connected to the inner surfaces of the limiting clamping plates 1159 on the same side. A clamping and cutting knife 1150 is fixedly connected to the left end of the limiting clamping plate 1159 on the left side.

[0055] Furthermore, the rear ends of the two clamping and cutting knives 1150 are both in mutual contact with the front end of the hollow tube 102.

[0056] When the cooled plastic is extruded from the front end of the extrusion secondary pipe 100, the motors two 1154 on both sides can be started, so that the motors two 1154 drive the disks 1155 fixedly connected to their output ends to rotate. The cylinders 1156 rotatably connected to the eccentric parts at the front ends of the disks 1155 will push the hollow elliptical plates 1157 to move. Under the limiting and guiding effects of the two limiting clamping plates 1159 on the same side, the two push rods 1158 on the same side can only move left and right along with the hollow elliptical plates 1157. Therefore, the push rods 1158 on both sides can drive the cutting knives 1150 fixedly connected thereto to move inward simultaneously, so as to realize the cutting process of the extruded plastic;

[0057] And the cut plastic parts can fall along the inclined plate 114 into the inner cavity of the water receiving box 111. The inner cavity of the water receiving box 111 is filled with water, which can cool and solidify the plastic parts falling into the inner cavity of the water receiving box 111;

[0058] And when the water needs to be drained subsequently, only by rotating and opening the rubber plug 113 can the water be drained from the drain port 112. Finally, the solidified plastic parts in the water receiving box 111 can be taken out.

[0059] It should be particularly noted that the specific installation methods, circuit connection methods and control methods of the motor one 94 and the motors two 1154 adopted in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
