Description

Technical Field

[0001] This invention relates to the field of rubber and plastic sheet production and processing technology, specifically to a thermal insulation rubber and plastic sheet molding machine and its thickness control pressure head. Background Technology

[0002] Thermal insulation rubber-plastic composite board is a commonly used insulation material, composed of rubber and plastic. It possesses excellent thermal insulation performance and elasticity, and can be used for thermal insulation of buildings, pipes, and equipment. A molding machine is a piece of equipment used to process rubber and plastic materials, shaping the softened material into the desired shape and size through the pressure and form of a mold. Molding machines are frequently used in the production and processing of thermal insulation rubber-plastic composite boards. First, the raw materials are heated to a certain temperature, then the softened rubber and plastic mixture is placed into the mold of the molding machine, followed by the application of pressure and temperature to shape it.

[0003] In existing technologies, during the use of thermal insulation rubber and plastic board molding machines, workers place the heated and softened rubber and plastic raw materials into a mold, and then mold them using a pressure head. However, rubber materials themselves have a certain odor (a unique smell of rubber). During the molding process, this odor will diffuse outwards and into the air, causing a decline in air quality and adversely affecting the health of workers, easily leading to symptoms such as respiratory discomfort and nausea. The pressure head used to mold the rubber and plastic raw materials is generally fixed by bolts, and its height is relatively fixed. Therefore, the thickness of the molded rubber and plastic finished product is also relatively fixed. When it is necessary to adjust the molding thickness of the rubber and plastic finished product, it is generally done by replacing pressure heads of different heights. The disassembly and assembly process is relatively troublesome, time-consuming, and affects the molding efficiency of the rubber and plastic board.

[0004] Therefore, we propose a thermal insulation rubber and plastic board molding machine and its thickness control head to solve the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In use, the present invention involves starting a fan to draw the odor emitted from the rubber and plastic raw materials in the lower mold body into multiple suction hoods through the suction holes. The odor then enters the square tube through a fixed pipe, and then into a connecting pipe. The drawn-in gas is sprayed downwards through the exhaust pipe. The sprayed airflow drives the arc-shaped blades to rotate, which in turn drives the rotating rod to rotate, thus achieving the rotation of multiple arc-shaped blades. The odor gas enters the annular adsorption bed along the arc of the arc-shaped blades. The adsorbent inside the bed can adsorb the odor gas. The rotation of the arc-shaped blades drives the gas flow, which is conducive to the full adsorption of odor gas and improves the adsorption effect. The treated air is discharged through the exhaust holes, thereby achieving the effect of gas treatment and reducing air pollution and the impact on human health.

[0017] 2. When in use, the electric heating plate generates heat and transfers it to the lower mold body. The temperature in the heating chamber is detected by a temperature sensor. When the temperature is abnormal, the temperature controller will control the power of the electric heating plate to avoid overheating. The heating component can keep the lower mold body within a certain temperature range, which makes it easier for the rubber and plastic raw materials to flow during molding, thereby improving the efficiency and quality of molding.

[0018] 3. When using this invention, starting the forward and reverse motors drives the drive gear to rotate, which in turn drives the ring gear and the two arc-shaped tracks to rotate together. This causes the two push rods to slide out from inside the two arc-shaped tracks. Under the spring's rebound, the connecting block, the moving rod, and the moving block are pushed outward, pulling the locking block out of the limiting groove. The two hydraulic rods are activated, pulling the ring plate and the two reinforcing rods to slowly move downward, further pushing the molding head downward, reducing its height, and increasing its depth into the lower mold body. During molding, the rubber and plastic raw material becomes thinner, reducing its thickness, thus achieving adjustment of the material molding thickness. At the same time, as the sliding block slowly slides in the transparent box, the camera takes pictures of the sliding block. When the bottom of the sliding block moves to the target colored marker bar, the PLC controller will control the two hydraulic rods to close and transmit the image information to the display, allowing the operator to see the adjustment status of the adjustment components.

[0019] 4. When using this invention, the forward and reverse motors are restarted, driving the drive gear to rotate in the opposite direction, which in turn drives the ring gear and the two arc-shaped tracks to rotate in the opposite direction. This causes the two push rods to gradually slide into the corresponding arc-shaped tracks and push the push rods to gradually move towards the reinforcing rod. At the same time, the connecting block and the moving rod are pushed to move, further pushing the locking block into the corresponding limiting groove to limit the reinforcing rod. Through the limiting component, the two reinforcing rods can be fixed in place, thereby providing auxiliary support for the molding head, improving its firmness and stability, and reducing shaking and instability during the molding process.

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.

[0023] Example 1: Please refer to Figures 1-12This invention provides a technical solution: a heat-insulating rubber and plastic board molding machine, comprising: a frame 1, a heating component 2 fixedly installed at the center of the top of the frame 1, and a processing component 3 disposed on the rear surface of the frame 1; the heating component 2 includes a lower mold body 201, and a heating chamber 207 is formed inside the lower mold body 201; the processing component 3 includes a fan 301, an air outlet pipe 302 fixedly connected to the output end of the fan 301, two fixing rings 306 fixedly installed on the rear surface of the frame 1, a processing box 305 fixedly installed inside the two fixing rings 306, and an annular adsorption bed 311 disposed inside the processing box 305. The outer surface of the treatment box 305 has an exhaust port 307. A rotating rod 312 is movably embedded inside the annular adsorption bed 311. Multiple arc-shaped blades 313 are fixedly installed on the outer surface of the rotating rod 312. A threaded cap 308 is threaded onto the front surface of the treatment box 305. One end of the rotating rod 312 is movably embedded in the rear wall inside the treatment box 305, and the other end is movably embedded in the front wall inside the threaded cap 308. One end of the exhaust pipe 302 is fixedly inserted into the interior of the treatment box 305. A connecting pipe 303 is fixedly connected to the output end of the fan 301. One end of the connecting pipe 303 is fixedly connected to... A square tube 304 has multiple fixed tubes 309 fixedly connected to its outer surface. One end of each fixed tube 309 is fixedly connected to a suction hood 310. Suction holes 206 are provided on the inner walls of the four sides of the lower mold body 201 near the top. One end of each fixed tube 309 is fixedly inserted into the heating chamber 207. The outer surfaces of the suction hoods 310 are fixedly installed on the inner walls of the heating chamber 207 near the suction holes 206. The outer surface of the square tube 304 is fixedly installed on the outer surface of the lower mold body 201 near the top. The bottom of the fan 301 is fixedly installed on the top of the frame 1. Near the rear surface, a control panel 9 is installed on one outer surface of the frame 1. A display 10 is installed on the front surface of the control panel 9. A temperature controller 7 is installed on the rear wall inside the frame 1. A PLC controller 8 is installed on the rear wall inside the frame 1 away from the temperature controller 7. A U-shaped plate 203 is fixedly installed inside the heating chamber 207. An electric heating plate 204 is installed on the top of the U-shaped plate 203. An inspection door 205 is installed on the front surface of the lower mold body 201 by screws. A temperature sensor 202 is installed on one outer surface of the lower mold body 201. The detection head of the temperature sensor 202 is fixedly inserted into the interior of the heating chamber 207.

[0024] The working principle of this embodiment is as follows: During use, the heating plate 204 is activated via the control panel 9 to generate heat, which is then transferred to the lower mold body 201. The temperature sensor 202 detects the temperature in the heating chamber 207 and transmits the detected temperature data to the temperature controller 7 via an electrical signal for identification and comparison. When the temperature is abnormal, the temperature controller 7 controls the power of the heating plate 204 to prevent overheating, which could cause the lower mold body 201 to overheat and affect the molding process of the rubber and plastic raw materials. The heating component 2 allows the lower mold body 201 to be maintained within a certain temperature range. The material flows more easily during molding of rubber and plastic raw materials, improving the efficiency and quality of molding. The blower 301 is started in advance. Workers place the softened rubber and plastic raw material into the lower mold body 201. Under the suction of the blower 301, the odor emitted from the rubber and plastic raw material in the lower mold body 201 is drawn through the suction holes 206 into multiple suction hoods 310. Then, it enters the square tube 304 through the fixed tube 309, and then into the connecting tube 303. Finally, the odorous gas is drawn into the treatment box 305 through the exhaust pipe 302. The annular adsorption bed 311 contains an adsorbent. The structure of the annular adsorption bed 311 is as follows: Figure 6 As shown, one end of the outlet pipe 302 is located at and in contact with the opening of the annular adsorption bed 311, and is limited by the annular adsorption bed 311 to prevent accidental rotation. The outlet pipe 302 faces the arc-shaped blades 313, which facilitates the outlet pipe 302 to spray the drawn gas downwards. The sprayed airflow drives the arc-shaped blades 313 to rotate, which in turn drives the rotating rod 312 to rotate, thereby realizing the rotation of multiple arc-shaped blades 313. As the arc-shaped blades 313 rotate, they can drive the sprayed odor gas to rotate inside the annular adsorption bed 311. The odor gas enters the annular adsorption bed 311 along the arc of the arc-shaped blades 313, and its interior... The adsorbent adsorbs odorous substances into its porous structure through surface adsorption, reducing odor emission. The rotation of the arc-shaped blades 313 drives gas flow, which is conducive to the full adsorption of odorous gases and improves the adsorption effect. The treated air is discharged through the exhaust port 307. Under the action of the treatment component 3, the gas treatment effect is achieved, reducing air pollution and the impact on human health. This solves the problem that rubber materials will produce odors during the use of the insulation rubber and plastic board molding machine, which will be emitted into the air, causing a decline in air quality and adversely affecting the health of workers, easily causing symptoms such as respiratory discomfort and nausea.

Multiple limiting grooves 413 are formed on the outer surfaces of both reinforcing rods 405, and the outer surfaces of the two locking blocks 513 are movably embedded inside two of these limiting grooves 413.

[0026] The working principle of this embodiment is as follows: When in use, the forward and reverse motor 502 is started. The output end of the forward and reverse motor 502 drives the drive gear 514 to rotate, which in turn drives the ring gear 503 meshing with it to rotate. At the same time, multiple fixed shafts 516 rotate inside the slide groove 605. The ring gear 503 is engaged by the limit rod 505 and the ring groove 504 to improve its rotational stability. Under the rotation of the ring gear 503, the two arc-shaped tracks 506 rotate together, causing the two push rods 511 to slide out from the two arc-shaped tracks 506 respectively. At this time, the spring 510 loses its compression and begins to rebound, pushing the connecting block 509 outward and driving the moving rod 508 to move outward. At the same time, it pulls the moving block 507. The sliding block 513 is pulled out of the limiting groove 413 by sliding in the moving groove 606. At this time, the two reinforcing rods 405 lose the limitation of the locking block 513 and become movable. Then, the two hydraulic rods 404 are activated at the same time, pulling the annular plate 403 to move slowly downward, which in turn drives the two reinforcing rods 405 to move slowly downward, further pushing the molding head 402 to move slowly downward in the protective frame 401. As the annular plate 403 moves, it drives the fixed block 407 and the movable rod 408 to move downward synchronously, so that the sliding block 414 slides slowly downward in the transparent box 409. The camera 411 is activated in advance. The annular plate 403 drives the detection plate 406 to move downward together, and keeps the camera 411 in a horizontal position with the sliding block 414. The camera 411 captures an image of the sliding block 414 and transmits the captured image information to the PLC controller 8 via an electrical signal. The PLC controller 8 is pre-programmed with an image of the sliding block 414 moving to the target colored marker bar 410. The PLC controller 8 identifies and analyzes the received image information. When the bottom of the sliding block 414 moves to the target colored marker bar 410, the PLC controller 8 controls the two hydraulic rods 404 to close and transmits the image information to the display 10 so that the operator can see the adjustment status of the adjustment component 4. At this time, the reinforcing rod 405 moves downward to the target position, and the locking block 513 aligns with the corresponding limiting groove 413, further realizing the high-pressure adjustment of the molding head 402. The height of the molding head 402 is adjusted to decrease, increasing its depth within the lower mold body 201. This makes it easier for the rubber and plastic material to thin out during molding, thus reducing its thickness and achieving the effect of adjusting the height of the molding head 402. This further adjusts the material molding thickness. Next, the forward and reverse motor 502 is restarted. The reverse rotation of the output of the forward and reverse motor 502 drives the drive gear 514 to rotate in the opposite direction, which in turn drives the ring gear 503 and the two arc-shaped tracks 506 to rotate in the opposite direction. This causes the two ejector rods 511 to gradually slide into the corresponding arc-shaped tracks 506 and slide along the arc-shaped inner wall of the tracks 506, gradually pushing the ejector rods 511 towards the reinforcing rod 405. Simultaneously, this pushes the connecting block 509 and the moving rod 508 to move, compressing the spring 510.Further pushing the moving block 507 moves the locking block 513 into the corresponding limiting groove 413, limiting the reinforcing rod 405. The limiting component 5 assists in fixing the two reinforcing rods 405, thereby providing auxiliary support for the molding head 402, improving its firmness and stability, reducing shaking and instability during molding. This solves the problem that the molding head height and the thickness of the molded rubber and plastic products are relatively fixed in the molding machine. When it is necessary to adjust the molding thickness of the rubber and plastic products, the method of replacing the molding head with one of different heights is generally used, which is cumbersome, time-consuming, and affects the molding efficiency of rubber and plastic sheets.

[0027] In this invention, during use, the temperature sensor 202, heating plate 204, fan 301, hydraulic rod 404, camera 411, forward / reverse motor 502, hydraulic cylinder 603, temperature controller 7, PLC controller 8, display 10, and control panel 9 are electrically connected. The control panel 9 sends corresponding operation commands to the PLC controller 8, which then activates or deactivates the corresponding equipment based on the received commands. Each transparent box 409 has multiple colored marker strips 410, each a different color from top to bottom. Multiple limiting grooves 413 are provided on the outer surface of the reinforcing rod 405, with a locking block 513 embedded in the lowest limiting groove 413. At this time, the bottom of the sliding block 414 is aligned with the uppermost colored marker strip 410, and the camera 411 is aligned with the sliding block 414. The control panel 9 activates the heating plate 204 to generate heat, which is then transferred to the lower mold body 201. The temperature sensor 202... 2. The temperature in the heating chamber 207 is detected, and the detected temperature data is transmitted to the temperature controller 7 via an electrical signal for identification and comparison. When the temperature is abnormal, the temperature controller 7 will control the power of the heating plate 204 to avoid overheating, which would cause the lower mold body 201 to be too hot and affect the molding of rubber and plastic raw materials. The heating component 2 can keep the lower mold body 201 within a certain temperature range, which makes it easier for the rubber and plastic raw materials to flow during molding, improving the efficiency and quality of molding. The blower 301 is started in advance, and the operator puts the softened rubber and plastic raw materials into the lower mold body 201. Under the suction of the blower 301, the odor emitted by the rubber and plastic raw materials in the lower mold body 201 is drawn into multiple suction hoods 310 through the suction hole 206, and then enters the square tube 304 through the fixed tube 309, and then enters the connecting tube 303. The odor gas is then sent to the treatment box 305 through the exhaust pipe 302. The annular adsorption bed 311 is equipped with an adsorbent. The structure of the annular adsorption bed 311 is as follows. Figure 6As shown, one end of the outlet pipe 302 is located at and in contact with the opening of the annular adsorption bed 311, and is limited by the annular adsorption bed 311 to prevent accidental rotation. The outlet pipe 302 faces the arc-shaped blades 313, which facilitates the outlet pipe 302 to spray the drawn gas downwards. The sprayed airflow drives the arc-shaped blades 313 to rotate, which in turn drives the rotating rod 312 to rotate, thereby realizing the rotation of multiple arc-shaped blades 313. As the arc-shaped blades 313 rotate, they can drive the sprayed odor gas to rotate inside the annular adsorption bed 311. The odor gas enters the annular adsorption bed 311 along the arc of the arc-shaped blades 313. The adsorbent inside adsorbs the odor substances into its pore structure through surface adsorption, reducing the emission of odor. The rotation of the arc-shaped blade 313 drives the gas flow, which is beneficial for fully adsorbing odor gases and improving the adsorption effect. The treated air is discharged through the exhaust port 307. Under the action of the treatment component 3, the gas treatment effect is achieved, reducing air pollution and the impact on human health. Then, the hydraulic cylinder 603 is activated, pushing the moving plate 604 downward, which in turn moves the limiting component 5 and the adjusting component 4 downward, so that the molding head 402 moves into the lower mold body 201 to mold the rubber and plastic raw material inside. When the molding head 402 needs to be adjusted, the forward and reverse motor 502 is activated. The rotation path of the output end of the forward and reverse motor 502 is preset. When the output end rotates to the preset path, it will automatically stop. When the forward / reverse motor 502 is restarted, its output end rotates in the opposite direction. The output end of the forward / reverse motor 502 extends into the support frame 501, driving the drive gear 514 to rotate, which in turn drives the ring gear 503 meshing with it to rotate. Simultaneously, multiple fixed shafts 516 rotate within the slide groove 605. The engagement of the limit rod 505 and the ring groove 504 improves the stability of the ring gear 503's rotation. The rotation of the ring gear 503 drives the two arc-shaped tracks 506 to rotate, causing the two push rods 511 to slide out from the two arc-shaped tracks 506 respectively. At this point, the spring 510 loses its compression and begins to rebound, pushing the connecting block 509 outwards. This causes the moving rod 508 to move outward, simultaneously pulling the moving block 507 to slide in the moving groove 606, further pulling the locking block 513 out of the limiting groove 413. At this point, the two reinforcing rods 405 lose the limiting effect of the locking block 513 and become movable. Then, the two hydraulic rods 404 are activated simultaneously. The output ends of the two hydraulic rods 404 move slowly, pulling the annular plate 403 to slowly move downward on the outer surface of the hydraulic cylinder 603. The reinforcing rods 405 are fixed to the mounting block 412 with bolts, thereby causing the two reinforcing rods 405 to slowly move downward, further pushing the molding head 402 to slowly move downward in the protective frame 401. As the annular plate 403 moves, it also causes the fixed block 407 and the moving rod 408 to move downward synchronously.The sliding block 414 slowly slides downwards in the transparent box 409. The camera 411 is activated in advance, and the annular plate 403 moves the detection plate 406 downwards together, keeping the camera 411 horizontal with the sliding block 414. The camera 411 captures an image of the sliding block 414 and transmits the captured image information to the PLC controller 8 via an electrical signal. The PLC controller 8 is pre-programmed with the image of the sliding block 414 moving to the target colored marker bar 410. The PLC controller 8 identifies and analyzes the received image information. When the bottom of the sliding block 414 reaches the target colored marker bar 410, the PLC controller 8 controls the two hydraulic rods 404 to close and transmits the image information to the display 10, allowing the operator to see the adjustment status of the adjustment component 4. At this time, the reinforcing rod 405 moves downwards to the target position, and the locking block 513 aligns with the corresponding limiting groove 413, further adjusting the height of the molding head 402, lowering its height, and allowing it to enter the next... The increased depth in the mold body 201 makes it easier for the rubber and plastic raw material to become thinner during molding, thus reducing its thickness. This allows for adjustment of the height of the molding head 402, further enabling adjustment of the material molding thickness. Then, the forward and reverse motor 502 is restarted. The reverse rotation of the output end of the forward and reverse motor 502 drives the drive gear 514 to rotate in the reverse direction, which in turn drives the ring gear 503 and the two arc-shaped tracks 506 to rotate in the reverse direction. This causes the two ejector rods 511 to gradually slide into the corresponding arc-shaped tracks 506 and move along the arc... The sliding of the arc-shaped inner wall of the track 506 gradually pushes the push rod 511 towards the reinforcing rod 405, simultaneously moving the connecting block 509 and the moving rod 508, and compressing the spring 510. This further pushes the moving block 507, moving the locking block 513 into the corresponding limiting groove 413, thus limiting the reinforcing rod 405. The limiting component 5 provides auxiliary fixation for the two reinforcing rods 405, thereby providing auxiliary support for the molding head 402, improving its firmness and stability, and reducing wobbling and instability during the molding process.
