Abstract
Description
Technical Field
[0001] This application relates to the field of ton bag production technology, specifically a cooling device for an extrusion stretching machine. Background Technology
[0002] In the production of ton bags, the extrusion stretching machine plays a crucial role. Plastic granules are heated and melted in the extruder, then extruded through a die to form a film, which is then stretched into flat filaments for use in ton bag production. The cooling device is an important component of the extrusion stretching machine, its function being to rapidly cool the extruded film or filaments to ensure product quality and performance. Currently, the common cooling method is to pass the extrudate through a cooling tank. The water in the cooling tank quickly removes the heat from the extrudate, causing it to cool and set rapidly.
[0003] However, in actual production, various impurities inevitably accumulate on the surface of the cooling pool. Currently, the cleaning of impurities on the surface of the cooling pool mainly relies on manual cleaning on a regular basis. However, manual cleaning is inefficient, requires a lot of manpower and time, and increases production costs. At the same time, manual cleaning is difficult to be timely and thorough. During the interval between two cleanings, impurities may adhere to the surface of the extrudate, affecting product quality and leading to an increase in the defect rate. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a cooling device for an extrusion stretching machine, which automatically collects impurities from the surface of the cooling pool. Compared with manual cleaning, this greatly improves cleaning efficiency, reduces labor costs, and provides more timely and thorough cleaning, reducing the occurrence of defective products due to impurities adhering to the extrudate. This solves the problems mentioned in the background technology.
[0005] To achieve the above objectives, this application provides the following technical solution: a cooling device for an extrusion stretching machine, comprising a base, an extrusion stretching machine body disposed on one side of the base, a cooling pool fixedly connected to the upper side of the base, a drive assembly disposed on the outer side of the base, a movable support disposed on the outer side of the base, two symmetrical cleaning assemblies disposed on the inner side of the movable support, each cleaning assembly comprising a fixed frame fixedly connected to the inner side of the movable support, an extrusion frame disposed on the outer side of the fixed frame, a collection filter bag disposed between the fixed frame and the extrusion frame, the fixed frame and the extrusion frame being fixedly connected by bolts, the extrusion frame and the movable support being fixedly connected by bolts, a pressure strip being fixedly connected to the outer side of the fixed frame, a drain pipe being fixedly connected to the inner side of the cooling pool, a drain outlet being opened on one side of the drain pipe, and a first filter screen being fixedly connected to the inner side of the drain outlet by bolts.
[0006] The above solution allows the moving support to move by setting a drive component, which in turn drives two sets of symmetrical cleaning components to move back and forth inside the cooling pool. The combination of the fixed frame, the extrusion frame, and the collection filter bag can automatically collect impurities on the surface of the cooling pool under the drive of the moving support. Compared with manual cleaning, this greatly improves cleaning efficiency, reduces labor costs, and makes cleaning more timely and thorough, reducing the occurrence of defective products caused by impurities adhering to the extruded material.
[0007] Furthermore, a water tank is fixedly connected to the upper surface of the base, the upper surface of the water tank is fixedly connected to the bottom surface of the cooling pool, a water pump is fixedly installed on one side of the water tank, a water supply pipe is fixedly connected to the output end of the water pump, and the other end of the water supply pipe is located on the upper side of the cooling pool.
[0008] The above solution provides a water source for the cooling pool through a water tank. The water pump and water pipes can transport the water in the tank to the cooling pool, realizing the circulation and replenishment of cooling water in the cooling pool, ensuring stable cooling effect, avoiding the impact of cooling efficiency due to reduced cooling water, and thus ensuring the production quality of ton bags.
[0009] Furthermore, a drainage cavity is provided on the inner side of the cooling pool, the inner wall of the drain pipe is connected to the inner wall of the drainage cavity, and the bottom surface of the drainage cavity is inclined.
[0010] With the above scheme, the inclined bottom surface of the drainage chamber allows the water flowing into the drainage pipe to flow steadily into the interior of the connecting pipe under its own gravity, so that it flows back into the interior of the water tank, thereby realizing the circulation of cooling water.
[0011] Furthermore, a connecting pipe is fixedly connected to the inner side of the water tank, and the other end of the connecting pipe is fixedly connected to the inner side of the drain cavity.
[0012] Through the above scheme, the connecting pipe connects the water tank and the drainage chamber, allowing the water that has undergone preliminary filtration in the drainage chamber to flow back to the water tank, thereby realizing the recycling of water resources, reducing water waste, lowering production costs, and ensuring a stable water level in the water tank to maintain the continuous replenishment of cooling water to the cooling pool.
[0013] Furthermore, a drawer is slidably connected to the inner side of the water tank, and a second filter screen is fixedly connected to the inner side of the drawer.
[0014] The above solution, through the combined action of the placement drawer and the second filter screen, can perform secondary filtration and collection of debris and other impurities generated in the cooling water flowing into the water tank, preventing these impurities from entering the cooling pool, reducing the generation of impurities in the cooling pool from the source, and improving the overall impurity treatment efficiency and product quality of the cooling device.
[0015] Furthermore, the cleaning assembly also includes two guide rods fixedly connected to the outside of the movable bracket, and the inner side of the squeezing frame is slidably connected to the outer side of the guide rods.
[0016] The above solution, by setting up guide rods, can provide guidance and support for the squeezing frame, ensuring the stability and reliability of the cleaning component's movement, making the collection filter bag collect impurities more stably and accurately and effectively, and avoiding the impact of the cleaning component's shaking on the impurity collection effect.
[0017] Furthermore, the drive assembly includes a mounting frame fixedly connected to the outside of the cooling pool, a lead screw rotatably connected to the inner side of the mounting frame, a servo motor fixedly embedded in the outer side of the mounting frame, the output end of the servo motor fixedly connected to one end of the lead screw, and the inner side of the movable bracket threadedly connected to the outer side of the lead screw.
[0018] The above scheme uses a servo motor to drive the lead screw to rotate, which in turn moves the movable bracket connected to the lead screw along the cooling pool direction, thereby realizing the automatic reciprocating motion of the cleaning component, saving manpower and time costs, and improving cleaning efficiency.
[0019] Furthermore, the drive assembly includes a guide rail fixedly connected to the outside of the cooling pool, and the outer side of the movable bracket is slidably connected to the inner side of the guide rail.
[0020] Through the above scheme, the guide rail can provide stable guidance and support for the movement of the mobile support, ensuring the stability of the mobile support when driving the cleaning component, preventing deviation or shaking during the movement, and enabling the cleaning component to clean the impurities on the surface of the cooling pool more efficiently and accurately, thereby improving the reliability and stability of impurity cleaning.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This extrusion stretching machine cooling device, through the setting of a drive component, can drive the movement of a movable support, and drive two sets of symmetrical cleaning components to move back and forth inside the cooling tank. The combination of the fixed frame, the extrusion frame and the collection filter bag can automatically collect impurities on the surface of the cooling tank under the drive of the movable support. Compared with manual cleaning, it greatly improves cleaning efficiency, reduces labor costs, and cleans more promptly and thoroughly, reducing the situation where impurities adhere to the extrudate and cause defective products. At the same time, the water tank provides water supply for the cooling tank. The setting of water pump and water pipe can transport water from the water tank to the cooling tank to realize the circulation and replenishment of cooling water in the cooling tank, ensuring stable cooling effect, avoiding the impact of cooling efficiency due to the reduction of cooling water, and thus ensuring the production quality of ton bags.

A drain cavity 9 is opened on the inner side of the cooling pool 3, and the inner wall of the drain pipe 7 is connected to the inner wall of the drain cavity 9. The bottom surface of the drain cavity 9 is inclined. The inclined bottom surface of the drain cavity 9 allows the water flowing into the drain pipe 7 to flow steadily into the interior of the connecting pipe 11 under the action of gravity, so that it flows back into the interior of the water tank 10, realizing the circulation of cooling water.
[0033] Please see Figure 1 , Figure 2 and Figure 5 The cleaning component 6 includes a fixed frame 601 fixedly connected to the inner side of the movable support 5, a squeezing frame 602 provided on the outer side of the fixed frame 601, and a collection filter bag 603 provided between the fixed frame 601 and the squeezing frame 602.

A pressure strip 604 is fixedly connected to the outer side of the fixed frame 601. The combination of the fixed frame 601, the squeezing frame 602 and the collection filter bag 603 can automatically cool the filter bag under the action of the movable support 5. The surface impurities of pool 3 are collected, which greatly improves cleaning efficiency and reduces labor costs compared to manual cleaning. The cleaning component 6 also includes two guide rods 605 fixedly connected to the outside of the movable bracket 5. The inner side of the squeezing frame 602 is slidably connected to the outside of the guide rods 605. By setting the guide rods 605, the squeezing frame 602 can be guided and supported, ensuring the stability and reliability of the movement of the cleaning component 6, making the collection filter bag 603 collect impurities more stably and more accurately and effectively, and avoiding the impact of the cleaning component 6 shaking on the impurity collection effect.
[0034] Please see Figure 1 , Figure 2 and Figure 3A water tank 10 is fixedly connected to the upper surface of the base 1. The upper surface of the water tank 10 is fixedly connected to the bottom surface of the cooling pool 3. A water pump 14 is fixedly installed on one side of the water tank 10. The output end of the water pump 14 is fixedly connected to a water delivery pipe 15, and the other end of the water delivery pipe 15 is located on the upper side of the cooling pool 3. In this scheme, the water tank 10 provides a water source for the cooling pool 3. The water pump 14 and the water delivery pipe 15 can transport the water in the water tank 10 to the cooling pool 3, realizing the circulation and replenishment of cooling water in the cooling pool 3, ensuring stable cooling effect, avoiding the impact of cooling efficiency due to reduced cooling water, and thus ensuring the production quality of ton bags. A connecting pipe 11 is fixedly connected to the inner side of the water tank 10, and the other end of the connecting pipe 11 is fixedly connected to the inner side of the drain cavity 9. A connecting pipe 11 connects the water tank 10 and the drain chamber 9, allowing the pre-filtered water in the drain chamber 9 to flow back to the water tank 10, thus achieving water resource recycling, reducing water waste, lowering production costs, and ensuring a stable water level in the water tank 10 to maintain a continuous supply of cooling water to the cooling pool 3. A drawer 12 is slidably connected to the inner side of the water tank 10, and a second filter screen 13 is fixedly connected to the inner side of the drawer 12. Through the combined action of the drawer 12 and the second filter screen 13, debris and other impurities generated in the cooling water flowing into the water tank 10 can be filtered and collected a second time, preventing these impurities from entering the cooling pool 3. This reduces the generation of impurities in the cooling pool 3 from the source, improving the overall impurity treatment efficiency and product quality of the cooling device.
[0035] Please see Figure 1 and Figure 6 The drive assembly 4 includes a mounting frame 401 fixedly connected to the outside of the cooling pool 3. A lead screw 402 is rotatably connected to the inside of the mounting frame 401. A servo motor 403 is fixedly embedded in the outside of the mounting frame 401. The output end of the servo motor 403 is fixedly connected to one end of the lead screw 402. The inner side of the moving bracket 5 is threadedly connected to the outer side of the lead screw 402. The servo motor 403 drives the lead screw 402 to rotate, which in turn drives the moving bracket 5, which is threadedly connected to the lead screw 402, to move along the direction of the cooling pool 3, thereby realizing the automatic reciprocating motion of the cleaning assembly 6, saving manpower and time costs, and improving cleaning efficiency. The drive assembly 4 also includes a guide rail 404 fixedly connected to the outside of the cooling pool 3. The outer side of the moving bracket 5 is slidably connected to the inner side of the guide rail 404. The guide rail 404 provides stable guidance and support for the movement of the moving bracket 5, ensuring the stability of the moving bracket 5 when driving the cleaning assembly 6, preventing deviation or shaking during movement, and enabling the cleaning assembly 6 to clean impurities on the surface of the cooling pool 3 more efficiently and accurately, thereby improving the reliability and stability of impurity cleaning.
[0036] In this embodiment, a cooling device for an extrusion stretching machine is provided. The driving component 4 drives the moving support 5 to move and drives two sets of symmetrical cleaning components 6 to reciprocate inside the cooling pool 3. The combination of the fixed frame 601, the extrusion frame 602 and the collection filter bag 603 can automatically collect impurities on the surface of the cooling pool 3 under the drive of the moving support 5. Compared with manual cleaning, this greatly improves cleaning efficiency, reduces labor costs, and makes cleaning more timely and thorough, reducing the occurrence of defective products caused by impurities adhering to the extrudate. At the same time, the water tank 10 provides water for the cooling pool 3. The water pump 14 and the water pipe 15 can transport the water in the water tank 10 to the cooling pool 3, realizing the circulation and replenishment of cooling water in the cooling pool 3, ensuring stable cooling effect, avoiding the impact of cooling efficiency due to reduced cooling water, and thus ensuring the production quality of ton bags.
[0037] The working principle of the above embodiment is as follows: After the extrusion stretching machine body 2 extrudes the ton bag material, the material enters the cooling pool 3 for cooling. The servo motor 403 starts, driving the lead screw 402 to rotate. This causes the movable support 5, which is threadedly connected to the lead screw 402, to reciprocate along the cooling pool 3 under the guidance of the guide rail 404. Then, the movable support 5 drives the cleaning component 6 to move. The collection filter bag 603, fixed by the fixed frame 601 and the extrusion frame 602, collects impurities on the surface of the cooling pool 3. At this time, the fixed frame 601 and the extrusion frame 602 are fixed to the collection filter bag 603 by bolts, which facilitates the disassembly of the collection filter bag 603 and makes it convenient for personnel to perform centralized cleaning. Afterwards, the water in the cooling pool 3 flows into the drain pipe 7 under the action of gravity. At this time, the first filter screen 8 filters the drainage to prevent impurities from flowing in. Then, the water in the drain pipe 7 flows into the drain chamber 9. The water in the drain chamber 9 that has undergone preliminary filtration flows back to the water tank 10 through the connecting pipe 11. Then, the water in the water tank 10 is replenished to the cooling pool 3 through the water supply pipe 15 under the action of the water pump 14, realizing the recycling of water resources. At the same time as the water flows back to the water tank 10 through the connecting pipe 11, the second filter screen 13 in the drawer 12 can perform secondary filtration of the water to reduce the source of impurities in the cooling pool 3. All components work together to realize the automatic cleaning of impurities in the cooling pool 3 and the recycling of cooling water, ensuring the production quality and efficiency of ton bag bags.
