Description

Technical Field

[0001] This invention relates to the field of environmentally friendly sponge production technology, and in particular to a hot pressing molding device for environmentally friendly sponge production. Background Technology

[0002] Eco-friendly sponge is a new type of environmentally friendly material made of polymers such as polyurethane or polyester. It boasts advantages such as softness, lightweight, durability, and fire resistance. Eco-friendly sponges are commonly used for cleaning, water absorption, slip prevention, heat insulation, and sound insulation. For example, they are used for cleaning floors, furniture, and appliances; for absorbing liquids and preventing slips; for heat insulation in buildings, vehicles, and homes; and for sound insulation and noise reduction in products such as headphones and speakers. The use of eco-friendly sponges can reduce the pollution and harm to the environment caused by traditional sponges, while also improving people's quality of life and health. In light of the above, it should be noted that: In the traditional hot-pressing process of environmentally friendly sponge production, polyurethane or polyester polymer materials are heated to a certain temperature according to production needs, and then pressure is applied in a mold to shape the raw material. By controlling parameters such as heating temperature, pressure, and time, sponge products of different shapes and specifications can be produced. However, due to the uncertainty of the sponge being fed into the mold, local areas of the sponge may extend into the sealing structure between the molds, resulting in heat leakage and incomplete hot pressing during the heat treatment of the sponge. Furthermore, traditional hot-pressing processes lack data collection and monitoring before and after the hot-pressing process, leading to deficiencies in the quality control of the hot-pressed products. To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

By collecting data in stages before and after the hot-pressing process, it obtains the internal environment fluctuation value in the early stage, the shape defect value and cotton body void value in the later stage, and efficiently monitors the heat treatment process of the sponge before, during, and after hot pressing. Specifically, it compares and analyzes the collected data with preset stored data to obtain relevant rating signals, and controls relevant components to perform compensatory operations accordingly. Therefore, it can provide double-sealed space treatment for the early hot-pressing process, ensuring the internal hot-pressing of the sponge and the internal locking of heat, and can also perform quality control screening of the environmentally friendly sponges after hot pressing on the feeding tray, thus solving the aforementioned problems.

The internal environment fluctuation value NHz and the overall fluctuation value MLz of the cotton material are then sent to the material review and analysis module via the processor. After receiving the internal environmental fluctuation value NHz and the overall cotton material fluctuation value MLz, the material review and analysis module immediately analyzes the processing efficiency within the hot pressing molding device. The specific analysis steps are as follows: The internal environmental fluctuation value NHz and the overall cotton material fluctuation value MLz within the time threshold are obtained.

Upon receiving the recycling signal, the signal execution module immediately controls the tilting cylinder arm to operate. If the quality control coefficient PKo < the preset quality control coefficient YKo, no signal is generated.

[0012] The beneficial effects of this invention are: (1) This invention collects data from the early and late stages of the hot pressing device in stages, and obtains the internal environment fluctuation value and cotton material wholeness fluctuation value in the early stage and the shape defect performance value and cotton body void value in the late stage.

[0015] 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.

[0016] Example 1: This example is used to solve the problem of lack of data collection and monitoring in the early and late stages of hot pressing of traditional sponges, which leads to defects in the quality supervision of hot-pressed products.

[0017] Please see Figure 1 - Figure 9As shown, this embodiment is a hot-press molding device for producing environmentally friendly sponges, including a base frame 1, a transport frame 2 mounted on the top of the base frame 1, a drag chain 205 mounted on the inner wall of the transport frame 2, a feeding tray 4 connected to the drag chain 205 at the top center of one end of the transport frame 2, a limiting top plate 5 penetrating the middle of the transport frame 2 at the top center of the base frame 1, a movable outer mold support 401 at the top of the feeding tray 4, a heat-conducting pad 404 at the top center of the movable outer mold support 401, and a sliding sleeve at the bottom of the feeding tray 4 connected to the bottom of the movable outer mold support 401. The tilting cylinder arm 405 has a control panel 7 installed on the outer wall of the top side of the base frame 1. The hot press box 3 located above the transport frame 2 is mounted on the top of the base frame 1. A vacuum pump 301 is embedded in the inner wall of the top of the hot press box 3. A hot press mold frame 305 is slidably arranged inside the hot press box 3. A movable top mold 306 is slidably arranged inside the hot press mold frame 305. An outer bottom frame 309 is provided at the bottom edge of the hot press mold frame 305. Multiple sets of contact plates 6 are sleeved inside the outer bottom frame 309. A locking block 604 is sleeved on the top of the outer bottom frame 309 above the contact plates 6. The control panel 7 is internally equipped with a processor, a data acquisition module, a material review and analysis module, a review and analysis module, and a signal execution module. The data acquisition module is used to collect the internal environmental fluctuation value NHz of the heat treatment environment inside the hot press mold frame 305 and the overall material fluctuation value MLz of the sponge material to be processed on the fixed inner mold support 402 during the use of the hot press molding device, and sends the internal environmental fluctuation value NHz to the material review and analysis module via the processor; 10 minutes during the use of the hot press molding device is set as the time threshold. It should be noted that: the internal environment fluctuation value NHz represents the average of the maximum and minimum values ​​of temperature and air pressure fluctuations in the internal space where the heat-conducting pad 404 and the etched heat-conducting plate 308 are spliced ​​within a time threshold. The magnitude of the internal environment fluctuation value NHz reflects the quality of the hot pressing processing environment of the sponge. The larger the internal environment fluctuation value NHz, the more likely there is damage to the seal between the heat-conducting pad 404 and the etched heat-conducting plate 308 within that time threshold. The cotton material overall fluctuation value MLz represents the overall quality data of the sponge to be processed within the time threshold. In addition, the internal environment fluctuation value NHz is collected by temperature and air pressure sensors installed inside the heat-conducting pad 404, and the cotton material overall fluctuation value MLz is collected by an object scanning sensor installed inside the fixed inner mold support 402. After receiving the internal environmental fluctuation value NHz and the overall fluctuation value MLz of the cotton material, the material review and analysis module immediately analyzes the processing efficiency within the hot pressing molding device. The specific analysis steps are as follows: The environmental fluctuation value NHz and the whole material fluctuation value MLz within the time threshold are obtained, and then processed by the formula. The processing coefficient JGi is obtained, where a and b are the proportional coefficients of the internal environmental fluctuation value NHz and the overall fluctuation value MLz of cotton, respectively, a>b>0, and JGi represents the processing coefficient. The preset processing coefficient YGi stored and entered in the processor is retrieved and compared with the processing coefficient JGi. If the processing coefficient JGi ≥ the preset processing coefficient YGi, it is determined that there is an abnormality in the use of the hot pressing molding device within the time threshold. A remedial signal is generated and sent to the review analysis module and the signal execution module via the processor. After receiving the remedial signal, the signal execution module immediately controls the vacuum pump 301 to work. When the hot pressing molding is abnormal, the vacuum pump 301 simultaneously extracts the air inside the outer sealed space through the air guide pipe 303, so that it forms a double vacuum area outside the heat-conducting pad 404 and the engraved heat-conducting plate 308. At the same time, it helps to lock the heat of the heater 307 and prevent leakage, which would lead to the problem of the hot pressing temperature of the sponge to be processed being insufficient and the processing being unqualified. If the processing coefficient JGi is less than the preset processing coefficient YGi, no signal will be generated.

[0018] Example 2: Please refer to Figure 1 - Figure 9 As shown, after receiving the remedial signal, the review and analysis module immediately controls the data acquisition module to collect the environmentally friendly sponge that has been hot-pressed on the fixed inner mold support 402, and obtains the shape defect performance value XQz and the cotton body void value MTz of the environmentally friendly sponge on the fixed inner mold support 402 respectively. The shape defect performance value XQz and the cotton body void value MTz are sent to the review and analysis module through the processor. It should be noted that: the shape defect performance value XQz represents the average of the maximum and minimum differences between the surface shape of the hot-pressed environmentally friendly sponge and the sample within the time threshold. The value of the shape defect performance value XQz reflects the quality of the environmentally friendly sponge. The larger the value of the shape defect performance value XQz, the greater the difference between the group of environmentally friendly sponges and the sample within the time threshold. The cotton body void value MTz represents whether there are voids inside the environmentally friendly sponge on the feeding bracket 4 within the time threshold. In addition, the shape defect performance value XQz is collected by an industrial camera installed on the inner wall of the hot-press box 3 near the straight discharge port 203, and the cotton body void value MTz is collected by an object scanning sensor installed inside the feeding bracket 4. Upon receiving the defect value XQz and the cotton body void value MTz, the review and analysis module immediately performs a quality control efficiency analysis on the environmentally friendly sponge processed by the hot-press molding equipment. The specific analysis process is as follows: The defect performance value XQz and cotton body void value MTz within the time threshold were obtained, and then processed by the formula The quality control coefficient PKo is obtained, where c and d are the proportional coefficients of the defect performance value XQz and the cotton body void value MTz, respectively, c>d>0. PKo represents the quality control coefficient, and the preset quality control coefficient YKo is retrieved from the processor and compared with the quality control coefficient PKo. If the quality control coefficient PKo ≥ the preset quality control coefficient YKo, it is determined that the environmentally friendly sponge formed within the time threshold is unqualified, a recycling signal is generated, and the generated signal is sent to the signal execution module via the processor. After receiving the recycling signal, the signal execution module rotates the bottom of one side of the flip cylinder arm 409 to the feeding tray 4, the rotating magnetic block 408 is energized to generate magnetic force and is connected to the rotating magnetic shaft on the bottom of the other side of the movable outer mold tray 401, the lifting cylinder 407 extends and pushes the bottom of the other side of the flip cylinder arm 405 and slides along its bottom limit, causing the flip cylinder arm 405 to rotate upward along one side of the connection point with the feeding tray 4, thereby lifting the movable outer mold tray 401 until it is lifted close to the external recycling conveyor belt, and the material picking robot arm on the external return conveyor equipment takes out the finished environmentally friendly sponge. If the quality control coefficient PKo < the preliminary quality control coefficient YKo, no signal will be generated.

[0019] Example 3: This example addresses the problem that uncertainty in the placement of the sponge to be processed can easily lead to localized areas of the sponge extending onto the sealing structure between the molds, resulting in heat leakage and incomplete hot pressing during the heat treatment of the sponge in the overall mold.

[0020] Please see Figure 1 - Figure 8 As shown, the hot-press molding device for producing environmentally friendly sponges in this embodiment includes a support rod 201 connected to the outer wall of one end of a base frame 1 at the bottom of one end of a transport frame 2; a straight discharge port 203 at the other end of the transport frame 2, with a side discharge port 202 on one side of the straight discharge port 203; an anti-detachment side plate 204 at the top of a drag chain 205; and an end plate 206 near the drag chain 205 at one end of the transport frame 2. The top of both ends of the feeding tray 4 are symmetrically equipped with tilting cylinder arms 405. The cylinder arm 405 is equipped with a lifting cylinder 407 that is rotatably connected to the feeding tray 4. A rotating magnetic block 408 is provided on the top of the side of the tilting cylinder arm 405 near the lifting cylinder 407. Tilting cylinder arms 406 are symmetrically arranged on the top of both sides of the feeding tray 4.

A rotating magnetic block 410 is provided at the top of one end of the tilting cylinder arm 406. In use, the sponge to be processed is placed on the top of the fixed inner mold tray 402. The drag chain 205 drives the feeding tray 4 to move close to the bottom of the hot press box 3 via the connector. The lifting cylinder 501 drives the limiting top plate 5 to slide up and contact the bottom of the feeding tray 4 via the connector. The pressure bottom plate 503 contacts the bottom of the feeding tray 4 and pushes back into the limiting top plate 5, and pushes the compression spring 502 to retract. At the same time, the pressure bottom plate 503 drives multiple sets of irregularly shaped blocks 505 to slide up via the deflection rod 504. The irregularly shaped blocks 505 are engaged with the bottom of the feeding tray 4 and locked to the transport frame 2. The bottom of the movable outer mold support 401 is provided with multiple sets of rotating magnetic suction shafts. The top center of the movable outer mold support 401 is snapped with a fixed inner mold support 402. The top of the fixed inner mold support 402 is provided with a protruding frame 403. The heat-conducting pad 404 is snapped into the inside of the protruding frame 403. A sealing groove 1 is recessed between the movable outer mold support 401 and the fixed inner mold support 403. A sealing groove 2 is recessed at the top center of the protruding frame 403. The bottom of the limiting top plate 5 is provided with a lifting cylinder 501 connected to the base frame 1. The top center of the limiting top plate 5 is sleeved with a pressure-bearing bottom plate 503. A compression spring 502 is installed at the bottom center of the pressure-bearing bottom plate 503. The tops of both sides of the limiting top plate 5 are sleeved with irregularly shaped clips 505. The bottom of the irregularly shaped clips 505 is provided with a deflection rod 504 that is movably sleeved at the bottom of the pressure-bearing bottom plate 503. The downward-pushing cylinder 302 drives the hot-press mold frame 305 to slide down via the connecting piece until the outer bottom frame 309 is submerged in the sealing groove. The contact plate 6 contacts the inner wall of the sealing groove and, under the influence of the continuous downward thrust of the hot-press mold frame 305, the contact plate 6 is forced to submerge into the bottom of the outer bottom frame 309. The limit spring 601 is compressed, and the inner cone 602 is pushed upward by the contact plate 6. The top inclined surface of the inner cone 602 contacts the inner inclined surface of the locking block 604. As the inner cone 602 slides upward, the locking block 604 moves outward along the transverse groove 603 and connects to the inner wall. The outer bottom frame 309 is engaged with the inner wall of the sealing groove, forming an outer sealing space between the hot press mold frame 305 and the movable outer mold support 401. The inner push cylinder 304 drives the movable top mold 306 to slide down through the connecting piece. The bottom of the movable top mold 306 is engaged with the convex frame 403, so that the heat-conducting pad 404 and the engraved heat-conducting plate 308 squeeze the sponge to be processed. The heater 307 starts to gradually heat up. The vacuum pump 301 draws the air between the heat-conducting pad 404 and the engraved heat-conducting plate 308 through the air guide pipe 303. The top inner wall of the hot press box 3 is provided with a rectangular array of multiple sets of downward pushing cylinders 302 connected to the hot press mold frame 305. The top of the hot press mold frame 305 is provided with an internal pushing cylinder 304 connected to the movable top mold 306.

Above the limiting spring 601 is a transverse groove 603 that fits into the locking block 604, and inside the transverse groove 603 is a tension spring that connects to the locking block 604. After the hot pressing of the sponge to be processed is completed, an environmentally friendly sponge is obtained. The inner push cylinder 304 and the lower push cylinder 302 respectively drive the movable top mold 306 and the hot pressing mold frame 305 to slide upward and reset. The lifting cylinder 501 drives the limiting top plate 5 to slide downward and reset. The drag chain 205 connects to the connecting piece. The feeding tray 4 is moved along one end of the straight discharge port 203. The bottom of one side of the flipping cylinder arm 409 is rotatably connected to the feeding tray 4. The rotating magnetic block 408 is energized to generate magnetic force and is connected to the rotating magnetic shaft on the other side of the bottom of the movable outer mold support 401. The lifting cylinder 407 extends and pushes the bottom of the other side of the flipping cylinder arm 405 and slides along its bottom limit, causing the flipping cylinder arm 405 to rotate upward along one side of the connection point with the feeding tray 4, thereby lifting the movable outer mold support 401 until it is lifted close to the external recycling conveyor belt. The finished environmentally friendly sponge is then taken out by the material picking robot arm on the external return conveyor equipment. The bottom of the other end of the flipping cylinder arm 406 is rotatably connected to the feeding tray 4. The rotating magnetic block 410 is energized to generate magnetic attraction and is connected to the rotating magnetic shaft at the bottom of one end of the movable outer mold tray 401. The lifting cylinder 409 extends and pushes the middle of one end of the flipping cylinder arm 406 and slides along its limit, causing the flipping cylinder arm 406 to rotate upward along the rotation point of the other end and the feeding tray 4. This lifts the movable outer mold tray 401 close to the external finished product conveyor belt, where the qualified environmentally friendly sponge is taken out by the picking robot arm on the external finished product conveyor belt and transported to the next processing step.

[0021] Combining Embodiment 1 and Embodiment 2, the limiting top plate 5 assists the feeding tray 4 in fixing and locking at a fixed point on the conveyor frame, causing it to be linked with the hot press box 3 to form a symmetrical and sealed locking mechanism. At the same time, the contact plate 6 assists the hot press mold frame 305 and the movable outer mold support 401 to form an outer sealed space, and the heat-conducting pad 404 and the engraved heat-conducting plate 308 squeeze and attach the sponge to be processed to lock it, forming a double heat-locking processing environment inside and outside. This improves the efficiency and quality of the hot pressing molding of the sponge, provides double sealing space treatment for the early hot pressing process, ensures the hot pressing treatment of the internal sponge and the internal locking of heat, and allows for quality control screening of the environmentally friendly sponge after hot pressing on the feeding tray 4.
