Description

Technical Field

[0001] The present invention relates to a method and equipment for processing and manufacturing injection molded parts, and in particular to a method and an automatic conveyor line for processing and manufacturing nylon fasteners soaked in water, belonging to the technical field of nylon parts soaked in water processing and manufacturing. Background Art

[0002] With the continuous development of rail transportation, the demand for rails and their accessories is increasing. Rail fasteners, as crucial rail fastening devices and consumables, have a broad market. This high market demand attracts a growing number of companies, leading to increasingly fierce competition. The quality and cost of nylon fasteners, among other factors, are crucial factors in determining market position.

[0003] Nylon is a highly hygroscopic material, with a water absorption rate exceeding 1%. This hygroscopicity is due to the amide groups in the nylon molecule. After absorbing moisture, the nylon material exhibits improved toughness and impact strength. However, after injection molding, the rapid cooling of nylon materials can lead to internal stress within the material, which can affect the toughness and durability of the product. Soaking in water can help the nylon macromolecules tend to a natural orientation and crystallize, thereby eliminating internal stress, improving the toughness of the product, and enhancing the stability of its internal structure, making it more durable during use and reducing the risk of breakage due to brittleness. Therefore, the use of nylon fasteners through water soaking is now increasingly being adopted.

[0004] However, when using the water soaking process for nylon fasteners, it is necessary to control the soaking temperature and soaking time to ensure that they have an appropriate water absorption rate. However, as the types of fasteners made of nylon increase, the requirements become more and more different, which leads to the need for various soaking conditions. However, most of the current soaking methods are to directly throw the nylon parts into a soaking pool for soaking, and then take them out after a certain period of time. However, this operation method has high labor intensity and is not suitable for large-scale production. In order to change this situation, it is now proposed to use a conveyor belt method to load the nylon fasteners that have just come out through a water tank through the conveyor belt, soaking them while running, and then taking the nylon fasteners out at the end of the water tank. , completing the soaking process; this method adopts a continuous soaking process, in which the nylon parts that need to be soaked are passed through the soaking tank at a uniform speed through an operating conveyor belt for soaking; but since the tank is fixed and, due to site limitations, the tank cannot be arbitrarily expanded or lengthened, the soaking time is also fixed; this may be relatively easy to meet the soaking requirements for a single nylon part, but it is very difficult to use the same tank to meet various requirements for nylon parts of various specifications and requirements, especially for nylon fasteners with very high requirements, it is necessary to ensure sufficient water absorption, which is difficult to achieve using the existing automated soaking method; therefore, it is very necessary to improve this.

[0005] The search did not find the same technical solution as the present invention, but only found some related comparative technical documents, mainly the following:

[0006] 1. Patent application number 202223054261.0 discloses an automatic conveying and cooling machine for injection molded parts, comprising a rectangular plate, a conveyor belt disposed on the upper surface of the rectangular plate, and fixedly connected to limit plates at positions symmetrically located on the upper surface and the front and rear sides of the conveyor belt, a plurality of circular holes being provided on one side of the limit plate, the interior of the circular holes being fixedly connected to a mounting plate, a fan being fixedly connected to one side of the mounting plate, vertical rods being fixedly connected at positions symmetrically located on the upper surface of the rectangular plate and at positions outside the limit plate, and the upper ends of the opposite sides of the two vertical rods being fixedly connected to a horizontal plate. This device facilitates the conveying and cooling of injection molded parts, facilitates the movement of injection molded parts, saves the cooling time of injection molded parts, facilitates quick collection, and avoids damage. The provision of a conveyor belt facilitates the conveying of injection molded parts, and the provision of a fan and an atomizer allows for quick cooling of injection molded parts, making them convenient to use.

[0007] 2. The patent with application number 202222914344.6 discloses a rapid condensation injection molding machine, which relates to the technical field of injection molding machines and aims to solve the problem that the cooling and demolding efficiency of injection molding machines is low and adjacent molds are easily fused. The key points of its technical solution are: it includes a machine body and a demolding mechanism installed in the machine body, the bottom wall of the machine body is fixedly connected to a cooling box, the cooling box is provided with a feed port and a discharge port, the demolding mechanism is located directly above the feed port, the inner wall of the cooling box is rotatably connected to a conveyor belt for transporting plastic parts, the demolding mechanism is located directly above the conveyor belt, and a number of separators are fixedly connected to the outer surface of the conveyor belt, and gaps for accommodating plastic parts are formed between adjacent separators. The utility model is fixedly connected to a spray assembly in the cooling box, and the spray port of the spray assembly is arranged toward the conveyor belt. The spray assembly sprays water onto the plastic parts on the conveyor belt through the spray port, which can accelerate the condensation of the plastic parts, thereby improving product quality.

[0008] 3. Patent application number 202021019342.5 discloses a cooling pool for the water quenching process of reflective materials, including: a water pool and a transmission device. The inner wall of the water pool is provided with a plurality of mounting seats, the side wall of the water pool is provided with an inlet pipe and an outlet pipe, the outlet pipe is provided with a filter screen, the water pool is provided with a detachable feed trough, and the bottom of the front end of the water pool is a concave structure; the transmission device is detachably provided on the mounting seat, the transmission device is tilted, the transmission belt of the transmission device is a filter screen structure for easy drainage, the bottom is located in the water pool, the outlet end of the transmission device is located outside the water pool, the transmission device is driven by a motor, the motor is provided at the front end of the water pool, and the motor and the transmission device are connected by a connector. It improves production efficiency, prevents a large amount of crystals from falling into the water pool, reduces the workload of cleaning the water pool in the later stage, and avoids personal injury.

[0009] Through the analysis of the above patents, it can be confirmed that the existing technology for the soaking of plastic parts in water has always remained in a simple soaking method or a simple water spray cooling, and has not paid attention to the soaking process or method. For the automatic conveying soaking, it is only simply considered as a continuous operation mode, and the plastic parts to be cooled are passed through a fixed water tank. Therefore, the plastic is only soaked in water, but does not meet the real soaking requirements; therefore, it is still necessary to improve it. Summary of the Invention

[0010] The technical problem addressed by this invention is this: To improve the quality of rail transit fasteners and reduce production costs, this patent proposes a nylon fastener soaking process and an automated conveyor line. By optimizing the soaking process, this method effectively improves the dimensional accuracy and mechanical properties of the nylon fasteners while reducing energy consumption and scrap rates. Furthermore, the design of the automated conveyor line further enhances production efficiency and reduces labor costs.

[0011] The technical solution proposed by the present invention is: a method for soaking nylon fasteners in water, wherein a material receiving belt brings newly formed nylon fasteners into a water tank of a water tank conveying assembly, and the nylon fasteners are placed on the conveyor belt so that all the nylon fasteners are immersed in water as a whole. The nylon fasteners move along the conveyor belt in the water tank until the soaking requirement is met, and then the nylon fasteners are taken out of the water tank by the conveyor belt and dropped into a material receiving box; the method is characterized in that: an intermittent operation mode is adopted, and the required soaking temperature and time are first determined according to the specific needs of the nylon fasteners, and then the required pause time and number are determined according to the length of the water tank and the conveying speed of the conveyor belt, so that after the determined number of pauses, the time when the conveyor belt takes the nylon fasteners out of the water tank is exactly the soaking time required by the nylon fasteners. This method can ensure that the nylon fastener soaking time meets the requirements.

[0012] Furthermore, the intermittent operation mode is to arrange the conveyor belt through the water trough, and one end of the conveyor belt is set in the water trough below the material connection belt to receive the nylon fasteners coming out of the molding equipment; the other end of the conveyor belt is raised from the end of the water trough and extends out of the water trough to bring the nylon fasteners soaked in water out of the water trough; a baffle is set at a certain distance on the conveyor belt, and the material connection belt brings the newly formed nylon fasteners into the baffle space; the distance of each intermittent operation of the conveyor belt is an integer multiple of the baffle spacing, and the soaking time is controlled by intermittent operation.

[0013] Furthermore, the time and number of pauses required are determined by controlling the conveyor belt from the material receiving belt to the nylon fastener in the water tank through an electrical control box, moving it to the other end of the conveyor belt, and driving the nylon fastener to the raised end, so that the number of pauses and time for the nylon fastener to exit the water can meet the time control requirements for the nylon fastener to be soaked in water.

[0014] Furthermore, the time and number of pauses required are determined based on the soaking time required for different nylon fasteners at the determined soaking temperature, the length of the water tank and the speed at which the conveyor belt is connected from the material receiving belt to the nylon fastener entering the water tank, and moves to the other end of the conveyor belt to drive the nylon fastener to the raised end, and the required number of pauses and pause time are calculated according to the integer multiples of the baffle spacing of each operation to ensure that the soaking time of the nylon fastener when it comes out of water is the required control time.

[0015] Furthermore, the calculation of the required number of pauses and pause time according to the integer multiples of the baffle spacing in each operation is to distribute the number of pauses and time to ensure that the shipment volume of each movement can meet the product shipment volume of the molding equipment.

[0016] Furthermore, the water temperature in the water tank is controlled by a temperature sensor. A water inlet and a water outlet are provided at both ends of the water tank. When the temperature is over or the water level is too low, water is added through the water inlet. When the water level is too high, water is discharged through the water outlet. The water temperature is controlled at 40-70℃.

[0017] Furthermore, the temperature of the nylon fastener when it comes out of water is controlled at 50-60°C, the water absorption rate of the nylon fastener reaches 0.3%-0.5%, and the flatness of the nylon fastener reaches 0.5mm.

[0018] Furthermore, the nylon fastener water-immersion automatic conveyor line of the nylon fastener water-immersion method includes a water trough, a material receiving belt, and a conveyor belt. One end of the conveyor belt is arranged at the bottom of one end of the water trough, below the material receiving belt, and the other end of the conveyor belt extends from the bottom of the water trough to the other end of the water trough, and is upward from the end to expose the water surface and the upper surface of the water trough, and extend outside the water trough.

[0019] Furthermore, a plurality of baffles are provided on the upper surface of the conveyor belt, so that the conveyor belt forms a spaced conveyor belt in sections, and the conveyor belt runs intermittently in the water trough in a manner that is a multiple of the spacing distance formed by the baffles.

[0020] Furthermore, a temperature controller is provided in the water tank, and the temperature control range is 40-70°C, which is the most suitable temperature for soaking nylon parts in water.

[0021] Furthermore, a water shield is arranged at the connection part between the conveyor belt and the material receiving belt section, which can shield the splashes generated by the nylon fastener falling into the water; the raised part of the conveyor belt is connected to the blanking chute, and the blanking chute is connected to the material receiving box.

[0022] The beneficial effects of the present invention are:

[0023] The present invention adopts an intermittent operation mode to soak the nylon fasteners in water, and controls the soaking time by controlling the number of pauses or the time. This can effectively ensure that different soaking operations can be carried out for different nylon fasteners. The main advantages are as follows:

[0024] (1) The intermittent operation mode is adopted, and the time that the nylon fastener stays in the water tank can be adjusted arbitrarily. Therefore, the same equipment and the same water tank length can be used for soaking different products; the soaking process of the nylon fastener is optimized, and the space requirements for the soaking process are reduced;

[0025] (2) Through the intermittent operation of the conveyor belt, the pause time or number of the conveyor belt can be controlled. The two can be flexibly selected to meet the product output needs of various molding equipment. The pause number and pause time of the intermittent operation can be matched according to the size of the product shipment and the soaking time requirement, and the most suitable matching pause time and number can be found; the water absorption rate and mechanical properties of the nylon fasteners are effectively improved, while reducing energy consumption and scrap rate;

[0026] (3) The intermittent operation mentioned above adopts the method of setting partitions on the conveyor belt and allowing the conveyor belt to run intermittently in the water tank according to the multiple of the conveyor belt interruption, which can ensure that the nylon fasteners can be effectively soaked in water in batches. The soaking time of each batch of nylon fasteners is uniform and there will be no confusion, thereby ensuring the soaking effect of the nylon fasteners;

[0027] (4) Thermometers are set at both ends of the water tank to control the water temperature at any time, further improving the water absorption accuracy of the water, and achieving the accurate water absorption rate required for each nylon fastener;

[0028] (5) By arranging a water shield at the connection part between the conveyor belt and the material receiving belt section, it can effectively prevent water splashing when the products coming out of the molding equipment fall into the water tank and pollute the production site.

[0032] The present invention is a technical improvement made by the inventor in the actual work process in order to solve a specific problem. In the existing nylon parts soaking in water, the inventor also set up a continuous automatic soaking line in order to realize the automatic soaking operation. Initially, a continuous soaking process was adopted, that is, the conveyor belt in the water tank was driven by a motor to run continuously. Since the speed of the motor is constant, the speed of the conveyor belt driven by the reducer in the water tank is also constant. In this way, for a single nylon fastener, the length of the water tank can be adjusted according to the requirements, or the reduction rate of the motor and the reducer can be adjusted to meet the soaking requirements; however, for multiple nylon fasteners with different soaking requirements, it is difficult to meet the soaking requirements of various nylon fasteners; there are two main reasons:

[0033] First, the length of the immersion tank is difficult to change, especially for workplaces with limited space. It is difficult to meet the immersion requirements of various nylon fasteners by adjusting the length of the tank.

[0034] The second is to adjust the speed of the motor to change the moving speed of the conveyor belt in the water tank to meet the soaking requirements of various nylon fasteners. A variable speed motor is required, but it is difficult to determine the specific conditions for the motor speed change of the nylon fastener, and it is also difficult to accurately control the speed of the motor. On the other hand, even if the speed conditions are met, after actual testing, it is found that this continuous operation still has a big problem, that is, in order to ensure that the conveyor belt can drive the nylon fasteners to move upward when the water is discharged, a partition must be added to the conveyor belt. However, when the conveyor belt moves at a uniform speed, it is easy for the molded nylon fasteners brought down by the material belt to fall onto the partition. This will cause some nylon fasteners in the same period to fall in front of the partition and some to fall behind the partition. In this way, two different soaking results will appear in the same period, thereby affecting the soaking effect of the product. For this reason, after repeated research, the inventor proposed an intermittent operation method for soaking operations; the following will be combined with the attached Figures 1 and 2 The present invention is further described. Specific embodiment 1

[0035] A method for soaking nylon fasteners in water, wherein the soaked nylon fasteners involved are straight-insert nylon lock buckles. According to the water absorption rate requirements of the straight-insert nylon lock buckles, it is necessary to soak the products in water at a water temperature of 40 degrees after they are formed. The water absorption rate of the nylon fasteners reaches 0.3%, and the flatness of the nylon fasteners reaches 0.5mm. According to calculations, the soaking time required is 60 minutes; injection molding is used for production, and the production batch size is 10 products per minute; the water tank length selected according to the site size is 6 meters, and the interruption of the conveyor belt 8 is 0.5 meters long per section. The nylon fastener soaking method of this embodiment includes the following steps:

[0036] A. Determine the relevant soaking parameters: for the straight-insert nylon lock, the required soaking time is 60 minutes, the water tank length is 6 meters, the soaking temperature is 40°, the conveying speed of the conveyor belt 8 is 0.1 m / s, and the production batch size is 10 products per minute.

[0037] B. Determine the intermittent operation mode based on the required soaking time: Based on the production batch size of 10 products per minute, and the interruption of the conveyor belt 8 is 0.5 meters long per section, the conveyor belt 8 needs to run at least once every 10 minutes; otherwise, there will be too many products in the same interruption; based on the length of the water tank of 6 meters, the effective soaking length of the conveyor belt 8 in the water tank is only 5 meters (leaving a 1-meter water outlet section), and the conveying speed of the conveyor belt 8 is 0.1 meters per second; the running time from beginning to end of each interruption is 45 seconds; there are 10 interruptions in the water; based on a pause for each interruption during operation, the number of pauses of the conveyor belt 8 in the water tank is 9 times; in order to meet the soaking time of 60 minutes, each pause should be 7 minutes.

[0038] C. The conveyor belt 8 is controlled by the electrical control box 3 to have a conveying speed of 0.1 m / s. The conveyor belt 8 operates intermittently, running for 5 seconds, moving 0.5 m per intermittent interval, so that the next intermittent interval is directly under the material receiving belt 2. It then pauses for 7 minutes. Regardless of the number of products in the intermittent interval, it will run for another 5 seconds, moving 0.5 m per intermittent interval, so that the next intermittent interval is directly under the material receiving belt 2. This process is repeated 9 times. After the first intermittent interval reaches the end of the water tank, it runs for another intermittent interval, and the water is discharged from the intermittent interval, completing the soaking process. The water is drained during the upward pause, and after reaching the top of the conveyor belt 8, the products fall into the receiving box 4, completing the soaking process. The soaking length is 5 meters, and the number of pauses is 9.

[0039] Note when working:

[0040] 1) The 2nd section of the splicing belt brings the newly formed straight-insert nylon lock into the baffles of the water tank conveying assembly 1, and places the straight-insert nylon lock on the conveyor belt 8 so that all the straight-insert nylon locks are immersed in water.

[0041] 2) The newly formed straight-insert nylon lock is dropped into the water tank to increase the water temperature, which is controlled by a temperature sensor. There are water inlets and outlets at both ends of the water tank. When the temperature is over-temperature or the water level is too low, water is added through the water inlet. When the water level is too high, water is drained through the water outlet. The water temperature is controlled at 40°.

[0042] 3) The conveyor belt 8 is operated intermittently at a conveying speed of 0.1 m / s. It pauses for 7 minutes after running 0.5 m. The length of the conveyor belt 8 is 5 m. After 9 pauses, the straight-insert nylon lock is brought from the water tank to the raised end. At this time, the straight-insert nylon lock has been immersed for 30 minutes.

[0043] 4) The straight-insert nylon lock buckle is dried on the drain mesh plate 6 , and the water droplets hanging on the straight-insert nylon lock buckle drip from the holes at the upper end of the drain mesh plate 6 .

[0044] 5) The conveyor belt 8 continues to move, and the straight-insert nylon lock falls from the raised section of the conveyor belt 8 into the receiving box 4. Specific embodiment 2

[0045] The nylon fastener soaking method of this embodiment includes the following steps:

[0046] A method for soaking nylon fasteners in water, wherein the soaked nylon fasteners involved are spring bar type I fasteners. According to the water absorption rate requirements of spring bar type I fasteners, it is necessary to soak the product in water at a water temperature of 50 degrees after molding, so that the water absorption rate of the nylon fastener reaches 0.4%, and the flatness of the nylon fastener reaches 0.5mm. According to calculation, the soaking time required is 90 minutes; injection molding is used for production, and the production batch size is 8 products per minute; the water trough length selected according to the site size is 7 meters, and the interruption of the conveyor belt 8 is 0.5 meters long per section. The nylon fastener soaking method of this embodiment includes the following steps:

[0047] A. Determine the relevant soaking parameters: For spring clip type I fasteners, the required soaking time is 90 minutes, the water tank length is 7 meters, the soaking temperature is 50°, the conveying speed of conveyor belt 8 is 0.1 m / s, and the production batch size is 10 products per minute.

[0048] B. Determine the intermittent operation mode based on the required soaking time: Based on the production batch size of 8 products per minute, and the interruption of the conveyor belt 8 is 0.5 meters long, the conveyor belt 8 needs to run at least once every 10 minutes; otherwise, there will be too many products in the same interruption; based on the length of the water tank of 7 meters, the effective soaking length of the conveyor belt 8 in the water tank is only 6 meters, and the conveying speed of the conveyor belt 8 is 0.1 meters per second; the running time from beginning to end of each interruption is 55 seconds; there are 12 interruptions in the water; based on one interruption pause each time the conveyor belt 8 runs, the number of pauses in the water tank is 11 times; in order to meet the soaking time of 90 minutes, each pause should be 8.5 minutes.

[0049] C. The conveyor belt 8 is controlled by the electrical control box 3 to have a conveying speed of 0.1 m / s. The conveyor belt 8 operates intermittently, running for 5 seconds, moving 0.5 m per intermittent interval, so that the next intermittent interval is directly under the material receiving belt 2. It then pauses for 8.5 minutes. Regardless of the number of products in the intermittent interval, it will run for another 5 seconds, moving 0.5 m per intermittent interval, so that the next intermittent interval is directly under the material receiving belt 2. This process is repeated 11 times. The first intermittent interval reaches the end of the water tank. The intermittent interval then rises to discharge water, completing the soaking process. The water is drained during the upward pause. After reaching the top of the conveyor belt 8, the products fall into the receiving box 4, completing the soaking process. The soaking length is 6 meters, and the number of pauses is 11.

[0050] Note when working:

[0051] 1) The 2nd section of the splicing belt brings the newly formed spring clip type I fasteners into the baffles of the immersion tank conveying assembly 1, and places the spring clip type I fasteners on the conveyor belt 8 so that all the spring clip type I fasteners are immersed in water.

[0052] 2) The newly formed spring bar I type fastener falls into the water tank to increase the water temperature, which is controlled by a temperature sensor. There are water inlets and outlets at both ends of the water tank. When the temperature is over-temperature or the water level is too low, water is added through the water inlet. When the water level is too high, water is discharged through the water outlet. The water temperature is controlled at 50°.

[0053] 3) The conveyor belt 8 operates intermittently at a conveying speed of 0.1 m / s, pausing for 7 minutes after running 0.5 m. The conveyor belt 8 is 6 m long. After 11 pauses, the spring clip type I fastener is brought from the water tank to the raised end. At this time, the spring clip type I fastener is immersed for 90 minutes.

[0054] 4) The spring bar type I fastener is dried on the drain mesh plate 6, and the water droplets hanging on the spring bar type I fastener drip from the holes at the upper end of the drain mesh plate 6.

[0055] 5) The conveyor belt 8 continues to move, and the spring bar type I fastener falls from the raised section of the conveyor belt 8 into the receiving box 4. Specific embodiment three

[0056] The nylon fastener soaking method of this embodiment includes the following steps:

[0057] A method for soaking nylon fasteners in water, wherein the soaked nylon fastener involved is a Type II fastener baffle seat. According to the water absorption rate requirement of the Type II fastener baffle seat, it is necessary to soak the product in water at a water temperature of 50 degrees after molding, so that the water absorption rate of the nylon fastener reaches 0.5%, and the flatness of the nylon fastener reaches 0.5mm. According to calculation, the soaking time required is 100 minutes; injection molding is used for production, and the production batch size is 10 products per minute; the water tank length selected according to the site size is 8 meters, and the interruption of the conveyor belt 8 is 0.5 meters long per section. The nylon fastener soaking method of this embodiment includes the following steps:

[0058] A. Determine the relevant soaking parameters: Type II fastener baffle seat, the required soaking time is 100 minutes, the water tank length is 8 meters; the soaking temperature is 50°; the conveying speed of conveyor belt 8 is determined to be 0.1 m / s; the production batch size is 10 products per minute.

[0059] B. Determine the intermittent operation mode based on the required soaking time: Based on the production batch size of 10 products per minute, the conveyor belt 8 has an interval of 0.5 meters. The conveyor belt 8 needs to run at least once every 10 minutes; otherwise, there will be too many products in the same interval. Based on the length of the water tank of 8 meters, the effective soaking length of the conveyor belt 8 in the water tank is only 7 meters, and the conveying speed of the conveyor belt 8 is 0.1 meters per second. The running time from beginning to end of each interval is 65 seconds. There are 14 intervals in the water. Based on the interval of pausing once per operation, the conveyor belt 8 pauses in the water tank 13 times. In order to meet the soaking time of 100 minutes, each pause should be 8 minutes.

[0060] C. The conveyor belt 8 is controlled by the electrical control box 3 to have a conveying speed of 0.1 m / s. The conveyor belt 8 operates in an intermittent manner, pausing for 8 minutes, then running for 5 seconds, moving 0.5 m between each intermittent movement, so that the next intermittent movement is directly under the material receiving belt 2. It then pauses for another 8.5 minutes. Regardless of the number of products in the intermittent movement, it then runs for another 5 seconds, moving 0.5 m between each intermittent movement, so that the next intermittent movement is directly under the material receiving belt 2. This process is repeated 13 times. After the first intermittent movement reaches the end of the water trough, it then rises and drains out of the water, completing the soaking process. The water is drained during the upward pause, and after reaching the top of the conveyor belt 8, the products fall into the receiving box 4, completing the soaking process. The soaking length is 7 meters, and the number of pauses is 13.

[0061] Note when working:

[0062] 1) The 2nd section of the material receiving belt brings the newly formed type II fastener baffle seat into the baffles of the water tank of the water immersion tank conveying assembly 1, and places the type II fastener baffle seat on the conveyor belt 8 so that all the type II fastener baffle seats are immersed in water as a whole.

[0063] 2) The newly formed Type II fastener baffle seat falls into the water tank to increase the water temperature, which is controlled by a temperature sensor. There are water inlets and outlets at both ends of the water tank. When the temperature is over-temperature or the water level is too low, water is added through the water inlet. When the water level is too high, water is discharged through the water outlet. The water temperature is controlled at 50°.

[0064] 3) The conveyor belt 8 operates at a conveying speed of 0.1 m / s in an intermittent operation mode, pausing for 9 minutes after running 0.5 m. The length of the conveyor belt 8 is 7 m. After 13 pauses, the Type II fastener baffle seat is brought from the water tank to the raised end. At this time, the soaking time of the Type II fastener baffle seat is 100 minutes.

[0065] 4) The type II fastener baffle seat is dried on the drain mesh plate 6, and the water drops hanging on the type II fastener baffle seat drip from the holes at the upper end of the drain mesh plate 6.

[0066] 5) The conveyor belt 8 continues to move, and the type II fastener baffle seat falls from the raised section of the conveyor belt 8 into the material receiving box 4.

[0067] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.

[0068] As can be seen from the above embodiments, the present invention also relates to a method for soaking nylon fasteners in water, wherein the newly formed nylon fasteners are brought into the water tank of the soaking tank conveying assembly 1 by means of the two sections of the material receiving belt, and the nylon fasteners are placed on the conveyor belt 8 so that all the nylon fasteners are immersed in water as a whole. The nylon fasteners move along the conveyor belt 8 in the water tank until the soaking requirement is met, and then the nylon fasteners are taken out of the water tank by the conveyor belt 8 and dropped into the material receiving box 4. The method is characterized in that the temperature and time required for soaking are determined according to the specific needs of the nylon fasteners, and the time and number of pauses required are determined according to the length of the water tank and the conveying speed of the conveyor belt 8, so that after the determined number of pauses, the time when the conveyor belt 8 takes the nylon fasteners out of the water tank is exactly the soaking time required for the nylon fasteners.

[0078] The beneficial technical effects of the present invention are:

[0079] The present invention adopts an intermittent operation mode to soak the nylon fasteners in water, and controls the soaking time by controlling the number of pauses or the time. This can effectively ensure that different soaking operations can be carried out for different nylon fasteners. The main advantages are as follows:

[0080] (1) The intermittent operation mode is adopted, and the time that the nylon fastener stays in the water tank can be adjusted arbitrarily. Therefore, the same equipment and the same water tank length can be used for soaking different products; the soaking process of the nylon fastener is optimized, and the site requirements of the soaking process are reduced;

[0081] (2) Through the intermittent operation of the conveyor belt, the pause time or number of the conveyor belt can be controlled. The two can be flexibly selected to meet the product output needs of various molding equipment. The number of pauses and the pause time of the intermittent operation can be matched according to the size of the product shipment and the soaking time requirements to find the most suitable matching pause time and number; effectively improving the water absorption rate and mechanical properties of nylon fasteners, while reducing energy consumption and scrap rate;

[0082] (3) The intermittent operation adopts the method of setting partitions on the conveyor belt and allowing the conveyor belt 8 to run intermittently in the water tank according to the multiple of the intermittent operation of the conveyor belt 8, which can ensure that the nylon fasteners can be effectively soaked in water in batches. The soaking time of each batch of nylon fasteners is uniform and there will be no confusion, thereby ensuring the soaking effect of the nylon fasteners;

[0083] (4) Thermometers are set at both ends of the water tank to control the water temperature at any time, further improving the water absorption accuracy of the soaking water and achieving the accurate soaking water absorption rate required for each nylon fastener;

[0084] (5) By arranging a water shield 5 at the connection portion between the conveyor belt 8 and the receiving belt 2, it is possible to effectively prevent water splashing when the product coming out of the molding equipment falls into the water tank, thereby polluting the production site.
