Technical Field
[0001] This invention relates to the field of PP roll material extrusion molding equipment, specifically a rapid cooling type PP roll material extrusion molding equipment. Background Technology
[0002] Extrusion molding equipment for PP roll material production is a type of intelligent manufacturing equipment. Traditional extrusion molding equipment for PP roll material production has limitations in cooling. It often relies on water cooling and air cooling with fixed power settings to cool the extruded material. The temperature of the material after extrusion is often not constant, and traditional cooling structures cannot adaptively adjust it. When the material temperature is high, the fixed power and fixed cooling distance cooling structure results in slow cooling speed, low efficiency, and high energy consumption, failing to meet the need for rapid cooling and even leading to product defects. When the material temperature is low, traditional cooling structures over-cool the material, wasting resources and affecting overall production efficiency and product quality. Therefore, we need a rapid-cooling extrusion molding equipment for PP roll material production to solve the above problems. Summary of the Invention
[0003] The purpose of this invention is to provide a rapid cooling extrusion molding equipment for producing PP roll materials, in order to solve the problems mentioned in the prior art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] The extrusion molding equipment includes a worktable, an extrusion tube, a drive module, a defoaming module, an extrusion head, and a cooling module. The extrusion tube is set on the worktable and fixedly connected to it. The drive module is inserted into one end of the extrusion tube and fixedly connected to it. One end of the extrusion head is fixedly connected to the other end of the extrusion tube, and the other end is fixedly connected to the cooling module. The defoaming module is set inside the extrusion tube near the end of the extrusion head and is rotatably connected to the extrusion tube. The defoaming module is fixedly connected to the drive module. The cooling module is set on the worktable and fixedly connected to it.
[0006] The workbench serves as the installation base for the extrusion molding equipment, maintaining its stability. Molten raw material enters the extrusion tube through the inlet. The drive module transfers the raw material from the inlet to the defoaming module. When the drive module is working, it simultaneously drives the defoaming module to rotate. As the raw material passes through the defoaming module, the internal bubbles are eliminated. It is then extruded through the extrusion head. The extruded strip material enters the cooling module for rapid cooling, improving production efficiency.
[0007] Furthermore, a feed funnel is provided at the inlet of the extrusion tube, and the feed funnel is fixedly connected to the extrusion tube.
[0008] The feed funnel facilitates the continuous entry of large quantities of raw materials into the extrusion tube.
[0009] Furthermore, the drive module includes a drive motor, a screw, and a mounting housing. The drive motor is fixedly connected to the worktable, the output rod of the drive motor is fixedly connected to the screw, the screw passes through the mounting housing, is inserted into the extrusion tube, and is rotatably connected to the mounting housing. The screw is fixedly connected to the defoaming module, and the mounting housing is fixedly connected to the extrusion tube and is located at one end of the extrusion tube.
[0010] The mounting shell helps fix and position the screw, and the drive motor drives the screw to rotate, which transmits the raw material in the extrusion tube. Under the continuous transmission and extrusion of the screw, the raw material is extruded from the extrusion head.
[0011] Furthermore, the defoaming module includes an extrusion cylinder and a defoaming rod. The extrusion cylinder is rotatably connected to the extrusion tube and is located inside the extrusion tube. The defoaming rod is fixedly connected to the screw, and the central axis of the defoaming rod coincides with the central axis of the screw. The defoaming rod is located inside the extrusion cylinder and is fixedly connected to the extrusion cylinder.
[0012] When the raw material is squeezed into the extrusion cylinder, the debubbling rod rotates continuously under the drive of the screw, constantly stirring the raw material, breaking and eliminating the air bubbles in the raw material, and improving product quality.
[0013] Furthermore, the extrusion cylinder is divided into two sections, which are connected end to end. The outlet of the extrusion cylinder closer to the extrusion head is smaller than the outlet of the other extrusion cylinder. Both extrusion cylinders are equipped with debubbling rods.
[0014] The outlet of the extrusion cylinder opposite to the extruder head is smaller than the inlet of the extrusion cylinder. After the raw material is stirred by the defoaming rod in the extrusion cylinder opposite to the extruder head, it is subjected to a first extrusion at the outlet of the extrusion cylinder opposite to the extruder head, thus compacting the raw material once. The raw material after the first compaction enters the next extrusion cylinder and is stirred again by the defoaming rod to further eliminate air bubbles. When it passes through the outlet of the next extrusion cylinder, the raw material is compacted a second time, further improving the air bubble elimination rate in the raw material.
[0015] Furthermore, the cooling module includes a primary cooling unit and a secondary cooling unit. One end of the primary cooling unit is fixedly connected to and communicates with the extruder head, and the other end of the primary cooling unit is fixedly connected to the secondary cooling unit. The secondary cooling unit is fixedly connected to the worktable.
[0016] The primary cooling unit pre-cools the extruded raw material to prevent quality problems such as cracks, bending, and flow marks from occurring during the material shaping process due to a sudden drop in temperature. The primary cooling unit and the secondary cooling unit work together to ensure that the cooling of the raw material proceeds gradually.
[0017] Furthermore, the primary cooling unit includes a primary cooling pipe and a bimetallic strip. The primary cooling pipe and the secondary cooling unit are fixedly connected. The primary cooling pipe is equipped with cooling pipes, adaptive pipes, and output pipes. The cooling pipes and adaptive pipes surround the output pipes. The primary cooling pipe is equipped with a cooling inlet, a cooling outlet, an adaptive inlet, and an adaptive outlet. One end of all cooling pipes converges at the cooling inlet, and the other end of all cooling pipes converges at the cooling outlet. One end of all adaptive pipes converges at the adaptive inlet, and the other end of all adaptive pipes converges at the adaptive outlet. One end of the bimetallic strip is arrayed inside the adaptive pipe, and the other end of the bimetallic strip is fixedly connected to the primary cooling pipe. An adjustment chamber is provided above the outlet of each output pipe, and some of the secondary cooling units are located inside the adjustment chamber.
[0018] Cooling water enters the cooling pipeline and the adaptive pipeline from the cooling inlet and the adaptive inlet, respectively. The raw material extruded from the extruder is transported in the output pipeline. The cooling water in the cooling pipeline cools the raw material in the output pipeline. When the temperature of the raw material in the output pipeline is higher than the preset value, the bimetallic strip is heated and bends to one side. The adaptive pipeline opens continuously, and cooling water enters the adaptive pipeline to supplement the cooling of the raw material in the output pipeline, thereby improving the cooling efficiency of the primary cooling unit.
[0019] Furthermore, the secondary cooling unit includes a blower pipe, a solenoid valve, a fixed housing, a conveyor roller, and an adjustment structure. The fixed housing is mounted on the worktable and fixedly connected to it. The fixed housing is also fixedly connected to the primary cooling pipe. The blower pipe is inserted into the fixed housing and fixedly connected to it. The blower pipe is located on the extension line of the output pipeline. Each blower pipe on the extension line of the output pipeline has a solenoid valve at its inlet. The solenoid valve is signal-connected to the adjustment structure. The conveyor roller is located below the output pipeline and is rotatably connected to the fixed housing. The adjustment structure is located in the adjustment chamber and fixedly connected to the primary cooling pipe.
[0020] After prolonged use, the cooling and adaptive pipes within the primary cooling unit may become clogged, reducing cooling efficiency. As raw materials exit the primary cooling unit, the regulating structure detects their temperature. When the detected temperature exceeds a preset value, the regulating structure sends a signal, which is received by a signal receiver within the solenoid valve. This causes the solenoid valve to open wider, allowing more airflow into the blowing pipe and faster cooling of the raw materials conveyed on the conveyor rollers. Conversely, when the detected temperature falls below the preset value, the regulating structure sends a signal, again receiving a signal receiver within the solenoid valve. This causes the solenoid valve to open narrower, allowing less airflow into the blowing pipe and a smoother cooling of the raw materials conveyed on the conveyor rollers, while also reducing noise.
[0021] Furthermore, the adjustment structure includes a shape reset component, a power supply, a circuit board, a brush, a resistor, and a slide. The shape reset component, power supply, circuit board, brush, resistor, and slide are all located inside the adjustment chamber. The slide is fixedly connected to the primary cooling pipe, the resistor is fixedly connected to the slide, the brush is slidably connected to the slide and also slidably connected to the resistor, the power supply is fixedly connected to the primary cooling pipe, the circuit board is fixedly connected to the primary cooling pipe and also connected to the solenoid valve signal. One end of the shape reset component is fixedly connected to the primary cooling pipe, and the other end is fixedly connected to the brush. The power supply, circuit board, brush, and resistor are connected in series.
[0022] The shape-resetting component is made of shape memory alloy. When heated, it deforms, causing the brush to slide on the slide block. This sliding motion changes the resistance of the circuit consisting of the power supply, circuit board, brush, and resistor. As the temperature inside the regulating chamber rises, the shape-resetting component causes the brush to slide, reducing the resistance and increasing the current. The circuit board detects this current change, and its signal generator sends a signal, which is received by the signal receiver on the solenoid valve, increasing the opening degree of the channel within the solenoid valve. Conversely, when the temperature inside the regulating chamber decreases, the shape-resetting component causes the brush to slide, increasing the resistance and decreasing the current. The circuit board detects this current change, and its signal generator sends a signal, which is received by the signal receiver on the solenoid valve, decreasing the opening degree of the channel within the solenoid valve, thus achieving adaptive control of the secondary cooling unit.
[0023] Compared with the prior art, the beneficial effects of the present invention are:
[0024] 1. The defoaming module of the present invention can eliminate air bubbles inside the molten raw material before extrusion molding, thus ensuring product quality;
[0025] 2. By setting up a primary cooling unit, the present invention can adaptively provide additional cooling and temperature reduction to the molding material passing through the primary cooling unit, ensuring that the molding material can be cooled to a preset temperature range after passing through the primary cooling unit.
[0026] 3. This invention achieves rapid cooling of the molding material by setting a secondary cooling unit. When the molding material is output from the primary cooling unit, the regulating structure detects the temperature of the molding material and then feeds it back to the solenoid valve. The solenoid valve controls the airflow in the blower pipe. When the temperature of the molding material is higher than the preset value, the solenoid valve opens more, the airflow increases, and the cooling rate of the molding material is improved. When the temperature of the molding material is lower than the preset value, the solenoid valve opens less, the airflow decreases, and the cooling is reduced to prevent excessively rapid cooling from affecting product quality.

[0037] 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.
[0038] Example: Figure 1 - Figure 9 As shown, this invention provides a technical solution for an extrusion molding equipment for the production of PP roll materials with rapid cooling:
[0039] like Figure 1 and Figure 2As shown, the extrusion molding equipment includes a worktable 1, an extrusion tube 2, a drive module 3, a defoaming module 4, an extrusion head 5, and a cooling module 6. The extrusion tube 2 is mounted on the worktable 1 and is fixedly connected to the worktable 1. The drive module 3 is inserted from one end of the extrusion tube 2 and is fixedly connected to the extrusion tube 2. One end of the extrusion head 5 is fixedly connected to the other end of the extrusion tube 2, and the other end is fixedly connected to the cooling module 6. The extrusion head 5 is mounted on the worktable 1 and is fixedly connected to the worktable 1. The defoaming module 4 is mounted inside the extrusion tube 2 near the end of the extrusion head 5 and is rotatably connected to the extrusion tube 2. The defoaming module 4 is fixedly connected to the drive module 3. The cooling module 6 is mounted on the worktable 1 and is fixedly connected to the worktable 1.
[0040] The workbench 1 serves as the installation base for the extrusion molding equipment, maintaining its stability. Molten raw material enters the extrusion tube 2 through its inlet. The drive module 3 conveys the raw material from the inlet of the extrusion tube 2 to the defoaming module 4. When the drive module 3 is working, it simultaneously drives the defoaming module 4 to rotate. When the raw material passes through the defoaming module 4, the internal bubbles are eliminated. Then, it is extruded through the extruder head 5. The extruded strip material enters the cooling module 6 for rapid cooling, improving production efficiency.
[0041] like Figure 1 and Figure 2 As shown, a feed funnel 21 is provided at the inlet of the extrusion tube 2, and the feed funnel 21 and the extrusion tube 2 are fixedly connected.
[0042] The feed funnel 21 is set up to facilitate the continuous entry of a large amount of raw material into the extrusion tube 2.
[0043] like Figure 2 As shown, the drive module 3 includes a drive motor 31, a screw 32, and a mounting shell 33. The drive motor 31 is fixedly connected to the worktable 1. The output rod of the drive motor 31 is fixedly connected to the screw 32. The screw 32 passes through the mounting shell 33, is inserted into the extrusion tube 2, and is rotatably connected to the mounting shell 33. The screw 32 is fixedly connected to the defoaming module 4. The mounting shell 33 is fixedly connected to the extrusion tube 2 and is located at one end of the extrusion tube 2.
[0044] The mounting shell 33 assists in fixing and positioning the screw 32. The drive motor 31 drives the screw 32 to rotate, which transmits the raw material in the extrusion tube 2. Under the continuous transmission and extrusion of the screw 32, the raw material is extruded from the extrusion head 5.
[0045] like Figure 5 As shown, the defoaming module 4 includes an extrusion cylinder 41 and a defoaming rod 42. The extrusion cylinder 41 is rotatably connected to the extrusion tube 2 and is disposed inside the extrusion tube 2. The defoaming rod 42 is fixedly connected to the screw 32. The central axis of the defoaming rod 42 coincides with the central axis of the screw 32. The defoaming rod 42 is disposed inside the extrusion cylinder 41 and is fixedly connected to the extrusion cylinder 41.
[0046] When the raw material is squeezed into the extrusion cylinder 41, the debubbling rod 42 rotates continuously under the drive of the screw 32, constantly stirring the raw material, breaking and eliminating the air bubbles in the raw material, and improving product quality.
[0047] like Figure 5 As shown, the extrusion cylinder 41 is divided into two sections, which are connected end to end. The outlet of the extrusion cylinder 41 closer to the extrusion head 5 is smaller than the outlet of the other extrusion cylinder 41. Both extrusion cylinders 41 are equipped with debubbling rods 42.
[0048] The outlet of the extrusion cylinder 41, which is away from the extruder head 5, is smaller than the inlet of the extrusion cylinder 41. After the raw material is stirred by the defoaming rod 42 in the extrusion cylinder 41, which is away from the extruder head 5, it is subjected to a first extrusion at the outlet of the extrusion cylinder 41, which compacts the raw material once. The raw material after the first compaction enters the next extrusion cylinder 41 and is stirred again by the defoaming rod 42 to further eliminate bubbles. When it passes through the outlet of the next extrusion cylinder 41, the raw material is compacted a second time, which further improves the elimination rate of bubbles in the raw material.
[0049] like Figure 1 and Figure 2 As shown, the cooling module 6 includes a primary cooling unit 61 and a secondary cooling unit 62. One end of the primary cooling unit 61 is fixedly connected to and communicates with the extruder head 5, and the other end of the primary cooling unit 61 is fixedly connected to the secondary cooling unit 62. The secondary cooling unit 62 is fixedly connected to the worktable 1.
[0050] The primary cooling unit 61 pre-cools the raw material after extrusion to prevent quality problems such as cracks, bending, and flow marks from occurring during the shaping process due to a sudden drop in temperature. The primary cooling unit 61 and the secondary cooling unit 62 work together to ensure that the cooling of the raw material proceeds gradually.
[0051] like Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, the primary cooling unit 61 includes a primary cooling pipe 611 and a bimetallic strip 612. The primary cooling pipe 611 and the secondary cooling unit 62 are fixedly connected. The primary cooling pipe 611 is provided with a cooling pipe 613, an adaptive pipe 614, and an output pipe 615. The cooling pipe 613 and the adaptive pipe 614 surround the output pipe 615. The primary cooling pipe 611 is provided with a cooling inlet 6111, a cooling outlet 6112, an adaptive inlet 6113, and an adaptive outlet 6114. One end of all cooling pipes 613 is connected to the cooling inlet. The cooling pipes 613 converge at 6111, and the other ends of all the cooling pipes 613 converge at the cooling outlet 6112. One end of all the adaptive pipes 614 converges at the adaptive inlet 6113, and the other end of all the adaptive pipes 614 converges at the adaptive outlet 6114. One end of the bimetallic strip 612 is arrayed inside the adaptive pipe 614, and the other end of the bimetallic strip 612 is fixedly connected to the primary cooling pipe 611. An adjustment chamber is provided above the outlet of each output pipe 615, and some of the secondary cooling units 62 are located inside the adjustment chamber.
[0052] Cooling water enters the cooling pipe 613 and the adaptive pipe 614 from the cooling inlet 6111 and the adaptive inlet 6113, respectively. The raw material extruded from the extruder 5 is transported in the output pipe 615. The cooling water in the cooling pipe 613 cools the raw material in the output pipe 615. When the temperature of the raw material in the output pipe 615 is higher than the preset value, the bimetallic strip 612 is heated and bends to one side. The adaptive pipe 614 opens continuously, and cooling water enters the adaptive pipe 614 to supplement the cooling of the raw material in the output pipe 615, thereby improving the cooling efficiency of the primary cooling unit 61.
[0053] like Figure 3 and Figure 9 As shown, the secondary cooling unit 62 includes a blower 621, a solenoid valve 622, a fixed housing 623, a conveyor roller 624, and an adjustment structure 625. The fixed housing 623 is mounted on the workbench 1 and is fixedly connected to the workbench 1. The fixed housing 623 is fixedly connected to the primary cooling pipe 611. The blower 621 is inserted into the fixed housing 623 and is fixedly connected to the fixed housing 623. The blower 621 is located on the extension line of the output pipe 615. A solenoid valve 622 is installed at the inlet of the blower 621 on each extension line of the output pipe 615. The solenoid valve 622 is signal-connected to the adjustment structure 625. The conveyor roller 624 is located below the output pipe 615 and is rotatably connected to the fixed housing 623. The adjustment structure 625 is located in the adjustment chamber and is fixedly connected to the primary cooling pipe 611.
[0054] After prolonged use, the cooling pipes 613 and adaptive pipes 614 within the primary cooling unit 61 may become clogged, reducing the cooling effect. Simultaneously, as raw materials are output from the primary cooling unit 61, the regulating structure 625 detects their temperature. When the detected temperature exceeds a preset value, the regulating structure 625 sends a signal, and a signal receiver within the solenoid valve 622 receives the signal. The solenoid valve 622 opens wider, allowing more airflow into the blowing pipe 621, thus cooling the raw materials conveyed on the conveyor roller 624 more quickly. Conversely, when the detected temperature falls below the preset value, the regulating structure 625 sends a signal, and the solenoid valve 622 opens narrower, allowing less airflow into the blowing pipe 621, resulting in a smoother cooling of the raw materials conveyed on the conveyor roller 624 and reduced noise.
[0055] like Figure 5 As shown, the adjustment structure 625 includes a shape reset component 6251, a power supply 6252, a circuit board 6253, a brush 6254, a resistor 6255, and a slide 6256. The shape reset component 6251, power supply 6252, circuit board 6253, brush 6254, resistor 6255, and slide 6256 are all located within the adjustment chamber. The slide 6256 is fixedly connected to the primary cooling pipe 611, and the resistor 6255 is fixedly connected to the slide 6256. The brush 625... 4 is slidably connected to the slide block 6256 and the resistor 6255. The power supply 6252 is fixedly connected to the primary cooling pipe 611. The circuit board 6253 is fixedly connected to the primary cooling pipe 611 and is signal-connected to the solenoid valve 622. One end of the shape reset component 6251 is fixedly connected to the primary cooling pipe 611, and the other end is fixedly connected to the brush 6254. The power supply 6252, the circuit board 6253, the brush 6254 and the resistor 6255 are connected in series.
[0056] The shape reset component 6251 is made of shape memory alloy and deforms when heated. This deformation causes the brush 6254 to slide on the slide block 6256. As it slides, the resistance of the circuit consisting of the power supply 6252, circuit board 6253, brush 6254, and resistor 6255 changes. When the temperature inside the regulating chamber rises, the shape reset component 6251 causes the brush 6254 to slide, reducing the resistance in the circuit and increasing the current. The circuit board 6253 detects this current change, and its signal generator sends a signal. The signal receiver on the solenoid valve 622 receives the signal, increasing the opening degree of the channel within the solenoid valve 622. Conversely, when the temperature inside the regulating chamber decreases, the shape reset component 6251 causes the brush 6254 to slide, increasing the resistance in the circuit and decreasing the current. The circuit board 6253 detects this current change, and its signal generator sends a signal. The signal receiver on the solenoid valve 622 receives the signal, decreasing the opening degree of the channel within the solenoid valve 622. This achieves adaptive control of the secondary cooling unit 62.
[0057] The working principle of this invention is as follows: The workbench 1 serves as the installation base for the extrusion molding equipment, maintaining the stability of the extrusion molding equipment. Molten raw material enters the extrusion tube 2 through the inlet of the extrusion tube 2. The drive module 3 conveys the raw material from the inlet of the extrusion tube 2 to the defoaming module 4. When the drive module 3 is working, it simultaneously drives the defoaming module 4 to rotate. When the raw material passes through the defoaming module 4, the internal bubbles are eliminated. Then, it is extruded through the extrusion head 5. The extruded strip material enters the cooling module 6 for rapid cooling, thereby improving production efficiency.
