Description

A sponge molding box for sponge production Technical Field

[0001] This utility model relates to the field of sponge production technology, specifically to a sponge molding box for sponge production. Background Technology

[0002] Sponge is a common polymer material with many varieties and extremely wide applications. In the sponge production process, the sponge molding box is one of the key pieces of equipment, which is used to contain raw materials and shape them.

[0003] The existing patent document CN214982669U discloses a sponge molding box for sponge production. This sponge molding box, by activating an electric telescopic cylinder, drives a telescopic rod, which in turn moves a sliding block to the right. This allows the sliding block to move a limiting block upwards. Simultaneously, the movement of the limiting block moves the molding box body upwards, facilitating material handling. It is simple to operate and convenient to use.

[0004] However, existing sponge molding boxes used in sponge production lack precise environmental monitoring and control mechanisms. Most devices lack built-in temperature and humidity sensors or are only equipped with a single temperature monitoring device, making it impossible to detect humidity changes in real time. This results in an inability to adjust molding environment parameters promptly. Furthermore, even if some devices have heating functions, temperature regulation relies on manual control, making it difficult to dynamically adjust according to the reaction process of the sponge raw materials. This can easily lead to problems such as excessively high temperatures causing carbonization of raw materials and excessively low temperatures causing incomplete curing. In terms of humidity control, traditional molding boxes generally lack humidity regulation components. They cannot effectively remove moisture when humidity is too high to prevent bubble collapse due to water vapor participating in the reaction, nor can they replenish moisture when humidity is too low to ensure the normal evaporation of the foaming agent. Ultimately, this results in defects such as uneven sponge density and disordered cell structure. This crude environmental control mode not only reduces the yield of sponge products but also increases raw material loss and production costs, making it difficult to meet the demands of modern industry for high-precision, high-quality sponge production. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a sponge molding box for sponge production, so as to solve the problem mentioned in the background art that the existing sponge molding boxes for sponge production are not convenient to ensure that they have a precise environmental monitoring and control mechanism during use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a sponge molding box for sponge production, comprising a box body, a partition fixedly disposed inside the box body, a control panel installed on the outer surface of the box body, and a box cover connected to the top of the box body;

[0009] A temperature and humidity sensor is embedded in the middle of the bottom of the box cover. The temperature and humidity sensor is electrically connected to the control panel. Heating wires are evenly arranged on the inner side wall of the box. The heating wires are electrically connected to the control panel. An air inlet pipe and an exhaust pipe are respectively provided on the outer side of the box. Solenoid valves are installed in both the air inlet pipe and the exhaust pipe.

[0010] Furthermore, a drive motor is fixedly installed on one side of the bottom end of the partition, and the transmission end of the drive motor is vertically and downwardly connected to a drive screw.

[0011] Furthermore, the end of the drive screw away from the drive motor is connected to the bottom of the housing via a bearing, and a moving block is connected to the outer surface of the drive screw via a threaded connection.

[0012] Furthermore, a movable plate is connected to one side of the movable block, and a connecting block is fixedly connected to the end of the movable plate away from the movable block. A connecting rod is provided at the bottom end of the partition, and the connecting block and the connecting rod are slidably sleeved together.

[0013] Furthermore, a support rod is vertically provided at the top of the movable plate, and the top of the support rod passes through the partition and is fixedly connected to the material placement plate.

[0014] Furthermore, a filter box is connected to the end of the exhaust pipe, and multiple sets of composite filters are arranged inside the filter box.

[0015] Furthermore, a sealing ring is provided around the bottom edge of the box cover, and the outer diameter of the sealing ring is interference-fitted with the inner diameter of the box body.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This sponge molding box for sponge production collects real-time environmental data inside the box through a temperature and humidity sensor embedded at the bottom of the box lid, and transmits the data to the control panel. The control panel precisely controls the start and stop of the heating wire and the opening and closing of the solenoid valves on the air inlet and exhaust pipes according to the preset program or actual monitoring data, thereby achieving precise regulation of the temperature and humidity inside the box. The stable and suitable temperature and humidity environment can ensure that the sponge raw material completes the foaming, curing and other molding processes under the best conditions, effectively avoiding quality problems such as uneven sponge density and bubble defects caused by temperature and humidity fluctuations, and significantly improving the quality of sponge products.

[0018] 2. The sponge molding box for sponge production uses a drive motor installed at the bottom of the partition to drive the drive screw to rotate, which in turn causes the moving block that is threaded with the drive screw to move up and down. The moving block drives the moving plate, connecting block, support rod and material plate to move synchronously. After the sponge is molded, the drive motor starts and can automatically push the material plate along with the molded sponge upward out of the box. No manual operation is required, which greatly reduces labor intensity, shortens demolding time, realizes rapid demolding, significantly improves the efficiency of sponge production, and facilitates mass production.

[0019] 3. This sponge molding box for sponge production, through a filter box connected to the end of the exhaust pipe and multiple sets of internal composite filters, can effectively filter impurities and harmful components in the exhaust gas, preventing pollution of the production environment and meeting environmental protection requirements. At the same time, the sealing ring at the bottom edge of the box cover is interference-fitted with the box body to form a good sealing structure. On the one hand, it can prevent external impurities from entering the box and affecting the sponge molding quality; on the other hand, it can ensure the stability of the temperature and humidity environment inside the box, reduce energy consumption, and further improve the practicality and environmental performance of the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5. This utility model provides a technical solution: a sponge molding box for sponge production, including a box body 1, a partition 2 fixedly arranged inside the box body 1, a control panel 3 installed on the outer surface of the box body 1, and a box cover 4 connected to the top of the box body 1.

[0028] A temperature and humidity sensor 5 is embedded in the middle of the bottom of the cover 4. The temperature and humidity sensor 5 is electrically connected to the control panel 3. Heating wires 6 are evenly arranged on the inner side wall of the box body 1. The heating wires 6 are electrically connected to the control panel 3. An air inlet pipe 7 and an exhaust pipe 8 are respectively provided on the outer side of the box body 1. Solenoid valves are installed in both the air inlet pipe 7 and the exhaust pipe 8.

[0029] When using this device for sponge production molding, turn on the control panel 3 of the S7-1200 series. Preset the required temperature range (25~35℃) and humidity range (40%~60%RH) for sponge molding through the human-machine interface. The temperature and humidity sensor 5 of the SHT30 model collects the initial environmental data inside the chamber in real time and transmits it to the control panel 3 for analysis. If the temperature inside the chamber is lower than the set value, the control panel 3 triggers the heating wire 6 to be energized for heating. When the temperature reaches the upper limit, the power is automatically cut off. The PID algorithm achieves precise temperature control of ±1℃. When the humidity is too high, the control panel 3 opens the solenoid valve of the exhaust pipe 8 to discharge moisture. When the humidity is too low, the solenoid valve of the air inlet pipe 7 is opened to introduce pre-treated moisture to maintain stable humidity.

[0030] A drive motor 9 is fixedly installed on one side of the bottom of the partition 2. The transmission end of the drive motor 9 is vertically and fixedly connected to the drive screw 10. The end of the drive screw 10 away from the drive motor 9 is connected to the bottom of the box 1 through a bearing. A moving block 11 is connected to the outer surface of the drive screw 10 through a threaded connection. A moving plate 12 is connected to one side of the moving block 11. A connecting block 13 is fixedly connected to the end of the moving plate 12 away from the moving block 11. A connecting rod 14 is provided at the bottom of the partition 2. The connecting block 13 and the connecting rod 14 are slidably sleeved. A support rod 15 is vertically provided at the top of the moving plate 12. The top of the support rod 15 passes through the partition 2 and is fixedly connected to the material placement plate 16. A filter box 17 is connected to the end of the exhaust pipe 8. Multiple sets of composite filter screens 18 are provided inside the filter box 17. A sealing ring 19 is provided around the bottom edge of the box cover 4. The outer diameter of the sealing ring 19 is interference-fitted with the inner diameter of the box 1.

[0031] The mixed sponge raw material, such as polyurethane prepolymer, is placed on the material placement plate 16. The box cover 4 is closed, and the sealing ring 19 ensures that the box 1 forms a sealed space. The raw material undergoes chemical reactions such as foaming and cross-linking under the set temperature and humidity environment. The temperature and humidity sensor 5 continuously monitors the environmental changes caused by the exothermic reaction and dynamically adjusts the working status of the heating wire 6 and the solenoid valve. After molding, the drive motor 9 is started, which drives the drive screw 10 to rotate, causing the moving block 11 to move along the drive screw 10. The moving block 11 drives the connecting block 13 to slide on the connecting rod 14 through the moving plate 12, thereby causing the support rod 15 to push the material placement plate 16 to rise and push the molded sponge out of the box 1, achieving rapid demolding. The composite filter 18 adopts a three-layer structure of primary filter particles + activated carbon adsorption of VOCs + HEPA sterilization. When the exhaust gas discharged from the exhaust pipe 8 passes through the filter box 17, the composite filter 18 intercepts dust, volatile organic compounds such as free TDI and odor molecules in sequence, and the purified gas meets the emission standards.

[0032] Working Principle: When using this device for sponge production molding, the control panel 3 (model S7-1200 series) is turned on. The required temperature range (25~35℃) and humidity range (40%~60%RH) for sponge molding are preset via the human-machine interface. The SHT30 temperature and humidity sensor 5 collects initial environmental data from inside the chamber in real time and transmits it to the control panel 3 for analysis. If the temperature inside the chamber is lower than the set value, the control panel 3 triggers the heating wire 6 to heat. When the temperature reaches the upper limit, the power is automatically cut off. Precise temperature control of ±1℃ is achieved through a PID algorithm. When the humidity is too high, the control panel 3 opens the solenoid valve of the exhaust pipe 8 to expel moisture. When the humidity is too low, the solenoid valve of the air inlet pipe 7 is opened to introduce pre-treated moisture to maintain stable humidity. The mixed sponge raw material, such as polyurethane prepolymer, is placed on the material plate 16, and the chamber lid is closed. 4. The sealing ring 19 ensures that the box 1 forms a sealed space. The raw materials undergo chemical reactions such as foaming and cross-linking under the set temperature and humidity environment. The temperature and humidity sensor 5 continuously monitors the environmental changes caused by the exothermic reaction and dynamically adjusts the working status of the heating wire 6 and the solenoid valve. After molding, the drive motor 9 starts and drives the drive screw 10 to rotate, so that the moving block 11 moves along the drive screw 10. The moving block 11 drives the connecting block 13 to slide on the connecting rod 14 through the moving plate 12, so that the support rod 15 pushes the material plate 16 to rise and push the molded sponge out of the box 1, realizing rapid demolding. The composite filter 18 adopts a three-layer structure of primary filter particles + activated carbon adsorption of VOCs + HEPA sterilization. When the exhaust gas discharged from the exhaust pipe 8 passes through the filter box 17, the composite filter 18 intercepts dust, volatile organic compounds such as free TDI and odor molecules in sequence, and the purified gas meets the emission standards.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
