Description

Technical Field

[0001] This utility model relates to the field of treadmill manufacturing technology, specifically a two-color treadmill side strip extrusion machine. Background Technology

[0002] Extrusion machines are important plastic machinery. Most plastic products can be produced and manufactured through extrusion molding. The motor of an extrusion machine is an important component of the machine, serving as its prime mover and providing the large thrust required by the screw. Treadmills are common fitness equipment in homes and gyms. A two-color treadmill side strip extrusion machine is needed in the production process of treadmills.

[0003] Existing extruders often have issues with material buildup. During operation, some material adheres to the inner cavity of the feed hopper. If not scraped off promptly, this not only wastes raw materials but also leads to incomplete mixing. Furthermore, existing extruders cannot effectively mix raw materials with other materials, making it difficult to scrape off the material adhering to the inner walls of the first and second feed cylinders, resulting in material waste. Additionally, cleaning the filter screen is inconvenient, easily causing clogging and hindering operation. Moreover, the heating efficiency of existing extruders is insufficient, reducing the heating efficiency of the electric heaters on the first and second extrusion frames, thus compromising the quality and stability of the molten plastic.

Temperature sensors are installed on the inner walls of the first extruder frame, the second extruder frame, the first feeding channel, and the second feeding channel. Feeding cylinders are installed on the top surfaces of the first and second feeding cylinders, respectively, and are connected to the interiors of the first and second feeding cylinders. Pressure sensors are installed on the inner walls of the homogenizing chamber. Perforated plates with equal spacing are opened on the inner walls of the first and second extruder frames. The surface of the filter screen is connected to the surfaces of the first and second feeding channels by screws. Support frames are installed on the bottom surfaces of the first and second extruder frames.

[0007] Preferably, the mixing mechanism consists of a stirring rod, a scraper, a stirring motor, a rotating rod, and a stirrer. The first and second feed cylinders are equipped with stirrers for mixing materials. Multiple sets of stirring rods are symmetrically installed on the surface of the stirrers. The first feed cylinder has multiple sets of scrapers arranged around the stirrers, with four sets of scrapers. The surface of one end of each stirring rod is fixed to the surface of the scraper, and the surface of each scraper is in contact with the inner wall of the first and second feed cylinders.

[0008] Preferably, a stirring motor is installed on the surface of the top center position of the first feed cylinder and the second feed cylinder, and a rotating rod is installed on the output end of the stirring motor through a coupling.

[0010] Preferably, a heating plate is installed on the inner wall of the cavity, and a first insulation layer is provided between the cavity and the heating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the dual-color treadmill edge strip extruder not only allows the extruder to scrape off the raw materials adhering to the inner walls of the first and second feed cylinders during use, enabling the materials to be quickly mixed with other raw materials and avoiding material waste, but also prevents the surface of the filter screen from becoming clogged during use, making the extruder easier to operate. Furthermore, it improves the heating efficiency of the electric heater on the inside of the first and second extruder frames, further ensuring the quality and stability of the plastic melt. The extruder is equipped with a mixing mechanism. Under the action of the mixing motor, the rotating rod is driven to rotate. When the rotating rod rotates, it drives the agitator to rotate inside the first and second feed cylinders. The agitator drives the mixing rod and scraper to rotate inside the first and second feed cylinders, so that the granular raw material is fully mixed with other raw materials that enter the first and second feed cylinders through the feeding cylinder. Under the action of the scraper, the raw material adhering to the inner wall of the first and second feed cylinders can be scraped off, realizing the mixing function of the extruder. This allows the extruder to scrape off the raw material adhering to the inner wall of the first and second feed cylinders during use, so that the material can be quickly mixed with other raw materials and avoid material waste. With a quick-release cleaning mechanism, users can loosen the mounting bolts on the surface of the fixing block and then pull the filter screen away from the first and second extruder frames. This causes the filter screen to slide along the guide block inside the guide groove. Under the combined action of the guide block and the guide groove, the filter screen is guided. At this time, the guide block moves the positioning block away from the inside of the first and second extruder frames, allowing the filter screen to be removed from the surface of the first and second extruder frames. This achieves the function of quick-release cleaning of the filter screen in the extruder, thus preventing the filter screen from becoming clogged during the use of the extruder and making the extruder easier to operate. By incorporating a high-efficiency heating mechanism, when the electric heater heats the raw materials inside the first and second extrusion frames, the combined effect of the second and first insulation layers within the cavity achieves better insulation of the inner walls of the first and second extrusion frames, improving energy utilization and reducing heat loss. The heating plate further enhances the heating efficiency of the first and second extrusion frames, realizing the high-efficiency heating function of the extruder. This improves the heating efficiency of the electric heater inside the first and second extrusion frames during extruder operation, further ensuring the quality and stability of the plastic melt.

A first material conveying channel 105 is provided on one side of the surface of the first extrusion frame 1, and a second material conveying channel 106 is provided on one side of the second extrusion frame 101. The second material conveying channel 106 communicates with the interior of the first material conveying channel 105. Both the first extrusion frame 1 and the second extrusion frame 101 are equipped with motor housings 109, and drive motors 108 are installed inside the motor housings 109. The model can be from the JO series. The input terminal of the drive motor 108 is electrically connected to the output terminal of the controller 11. The output terminal of the drive motor 108 is connected to a rotating shaft 116 via a coupling. The first extruder frame 1 has a feeding chamber 111, a melting chamber 112, and a homogenizing chamber 113. Both the first extruder frame 1 and the second extruder frame 101 are equipped with a feeding screw 115. The feeding screw 115 rotates and engages with the inner walls of the feeding chamber 111, the melting chamber 112, and the homogenizing chamber 113, respectively. The surface of the feeding screw 115 is fixed to the surface of the rotating shaft 116. The first extruder frame 1, the second extruder frame 101, and the first feeding channel 105 are connected. Temperature sensors 114, which can be of the TC series, are installed on the inner walls of both the first and second feed channels 106. The input terminals of the temperature sensors 114 are electrically connected to the output terminals of the controller 11. Feeding cylinders 117 are installed on the top surfaces of both the first and second feed cylinders 102 and 103, respectively, and are connected to the interiors of the first and second feed cylinders 102 and 103. A pressure sensor 118, which can be of the PT series, is installed on the inner wall of the homogenization chamber 113. The input terminal of the pressure sensor 118 is electrically connected to the output terminal of the controller 11. Perforated plates 119 with equal spacing are provided on the inner walls of both the first extruder frame 1 and the second extruder frame 101.Both the inner walls of the first extrusion frame 1 and the second extrusion frame 101 are equipped with filter screens 120. The surfaces of the filter screens 120 are connected to the surfaces of the first material conveying channel 105 and the second material conveying channel 106 respectively by screws. Support frames 110 are installed at the bottom of both the first extrusion frame 1 and the second extrusion frame 101.

[0018] Furthermore, such as Figure 2 and Figure 3 As shown, quick-release cleaning mechanisms 4 are provided on the inner walls of the first extrusion frame 1 and the second extrusion frame 101 and on the surface of the filter screen 120. The quick-release cleaning mechanism 4 consists of a fixing block 41, a guide groove 42, a mounting bolt 43, a guide block 44, and a positioning block 45. The surface of the filter screen 120 is symmetrically equipped with guide blocks 44. The inner walls of the first extrusion frame 1 and the second extrusion frame 101 are provided with guide grooves 42 for sliding cooperation with the guide blocks 44. The surface of the guide blocks 44 is equipped with positioning blocks 45, which are respectively engaged with the inner walls of the first extrusion frame 1 and the second extrusion frame 101. The surface of the filter screen 120 is symmetrically equipped with fixing blocks 41, which are connected to the first extrusion frame 1 and the second extrusion frame 101 by mounting bolts 43.

[0019] In practice, the user loosens the mounting bolts 43 on the surface of the fixing block 41, and then pulls the filter screen 120 away from the first extruder frame 1 and the second extruder frame 101. This causes the filter screen 120 to slide the guide block 44 inside the guide groove 42. Under the combined action of the guide block 44 and the guide groove 42, the filter screen 120 is guided, and the filter screen 120 can be removed from the surface of the first extruder frame 1 and the second extruder frame 101 respectively. The filter screen 120 can then be disassembled and cleaned, thus realizing the function of quick disassembly and cleaning of the filter screen 120 by the extruder.

[0020] Furthermore, such as Figure 2 and Figure 4As shown, a mixing mechanism 2 is provided inside the first feed cylinder 102 and the second feed cylinder 103. The mixing mechanism 2 consists of a stirring rod 21, a scraper 22, a stirring motor 23, a rotating rod 24, and a stirrer 25. A stirrer 25 for mixing materials is provided inside the first feed cylinder 102 and the second feed cylinder 103. Multiple sets of stirring rods 21 are symmetrically mounted on the surface of the stirrer 25. Multiple sets of scrapers 22 are arranged around the stirrer 25 inside the first feed cylinder 102, with four sets of scrapers 22. The surface of one end of each stirring rod 21 is respectively aligned with the surface of the scraper 22. With the surfaces fixed, the surface of the scraper 22 contacts the inner walls of the first feed cylinder 102 and the second feed cylinder 103 respectively. A stirring motor 23 is installed on the surface of the top center position of the first feed cylinder 102 and the second feed cylinder 103. The stirring motor 23 can be of the JO series. The input end of the stirring motor 23 is electrically connected to the output end of the controller 11. A rotating rod 24 is installed on the output end of the stirring motor 23 through a coupling. The bottom end of the rotating rod 24 extends into the interior of the first feed cylinder 102 and the second feed cylinder 103 and is fixed to the surface of the top position of the stirrer 25.

[0021] During implementation, the stirring motor 23 is controlled to work, and the stirring motor 23 drives the rotating rod 24 to rotate. When the rotating rod 24 rotates, it drives the agitator 25 to rotate inside the first feed cylinder 102 and the second feed cylinder 103. The agitator 25 drives the stirring rod 21 and the scraper 22 to rotate inside the first feed cylinder 102 and the second feed cylinder 103. Under the combined action of the agitator 25 and the stirring rod 21, the granular raw materials inside the first feed cylinder 102 and the second feed cylinder 103 are stirred. Under the action of the scraper 22, the raw materials adhering to the inner wall of the first feed cylinder 102 and the second feed cylinder 103 can be scraped off, so as to realize the mixing function of the extruder.

[0022] Furthermore, such as Figure 2 and Figure 5 As shown, the inner walls of the first extrusion frame 1 and the second extrusion frame 101 are provided with a high-efficiency heating mechanism 3. The high-efficiency heating mechanism 3 includes a first insulation layer 31, a second insulation layer 32, a cavity 33 and a heating plate 34. The inner walls of the first extrusion frame 1 and the second extrusion frame 101 are provided with cavities 33. The inner walls of the cavities 33 are provided with a second insulation layer 32 for heat preservation of the interior of the first extrusion frame 1 and the second extrusion frame 101. The inner walls of the cavities 33 are provided with heating plates 34. The first insulation layer 31 is provided between the cavity 33 and the heating plate 34. The surface of the first insulation layer 31 is fixed to the surface of the second insulation layer 32 and the surface of the heating plate 34, respectively.

[0023] During implementation, the combined effect of the second insulation layer 32 and the first insulation layer 31 inside the cavity 33 can achieve better insulation effect on the inner walls of the first extrusion frame 1 and the second extrusion frame 101, improve energy utilization, and reduce heat loss. Under the action of the heating plate 34, the heating efficiency inside the first extrusion frame 1 and the second extrusion frame 101 can be improved, so as to realize the function of high-efficiency heating of the extruder.

[0024] Working principle: In use, first place the first extruder frame 1 in the designated position. The user feeds different colored granular materials into the first feed cylinder 102 and the second feed cylinder 103 through the feeding cylinder 117. The granular materials enter the first extruder frame 1 and the second extruder frame 101 through the feeding pipe 107. The user operates the controller 11 to control the drive motor 108 to work. Under the action of the drive motor 108, the rotating shaft 116 is driven to rotate. When the rotating shaft 116 rotates, it drives the conveying screw 115 to move between the feeding chamber 111 and the melting chamber 1. The internal rotation of the homogenization chamber 113 and the feeding screw 115 continuously transports the granular material inside the first extrusion frame 1 and the second extrusion frame 101 from the feeding chamber 111 to the melting chamber 112. Subsequently, the controller 11 controls the electric heater 104 to work, generating high temperature under the action of the electric heater 104, heating the granular material inside the first extrusion frame 1 and the second extrusion frame 101, melting the granular material into a viscous flow state. The propulsive force of the feeding screw 115, through its cooperation with the gap between the inner walls of the first extrusion frame 1 and the second extrusion frame 101, propels the molten material... The raw materials are conveyed into the homogenization chamber 113 and continuously extruded to plasticize the molten material. Subsequently, raw materials of different colors inside the first extruder frame 1 and the second extruder frame 101 are continuously and stably fed into the first material conveying channel 105 and the second material conveying channel 106 through the perforated plate 119 and the filter screen 120, respectively. Then, they are extruded into the external mold. Through the flow channels of the mold, the raw materials and the flow channels in the mold form a continuous body with the same shape. After being cooled and shaped in the external cooling and shaping water tank, they are pulled out with the help of a traction device to obtain a continuous two-color treadmill edge. The device monitors the temperature inside the first extrusion frame 1, the second extrusion frame 101, the first material conveying channel 105, and the second material conveying channel 106 in real time under the action of temperature sensor 114, and sends the monitoring results to controller 11 to ensure that the raw material melts and plasticizes at a suitable temperature. Under the action of pressure sensor 118, the device can monitor the pressure of the raw material during extrusion. Pressure sensor 118 displays the monitoring results on the surface of controller 11. By observing controller 11, the user can determine whether the extrusion process of the raw material inside the first extrusion frame 1 and the second extrusion frame 101 is going smoothly.

[0025] Subsequently, after the material enters the first feed cylinder 102 and the second feed cylinder 103, the controller 11 controls the stirring motor 23 to work. Under the action of the stirring motor 23, the rotating rod 24 rotates. When the rotating rod 24 rotates, it drives the agitator 25 to rotate inside the first feed cylinder 102 and the second feed cylinder 103. When the agitator 25 rotates, it drives the stirring rod 21 and the scraper 22 to rotate inside the first feed cylinder 102 and the second feed cylinder 103. Under the combined action of the agitator 25 and the stirring rod 21, the granular raw materials inside the first feed cylinder 102 and the second feed cylinder 103 are processed. The mixing process ensures that the granular raw materials are fully mixed with other raw materials entering the first feed cylinder 102 and the second feed cylinder 103 through the feeding cylinder 117. Under the action of the scraper 22, the raw materials adhering to the inner walls of the first feed cylinder 102 and the second feed cylinder 103 can be scraped off, avoiding waste caused by the raw materials sticking to the inner walls of the first feed cylinder 102 and the second feed cylinder 103. This achieves the mixing function of the extruder, allowing the extruder to scrape off the raw materials adhering to the inner walls of the first feed cylinder 102 and the second feed cylinder 103 during use, so that the material can be quickly mixed with other raw materials and avoid material waste.

[0026] Subsequently, the filter screen 120 filters out impurities, unplasticized particles, and decomposition residues from the raw materials inside the first extrusion frame 1 and the second extrusion frame 101. After prolonged use, the filter screen 120 needs to be cleaned regularly to ensure the normal operation of the first extrusion frame 1 and the second extrusion frame 101. The user loosens the screws connecting the first feed channel 105 and the second feed channel 106, removes the first feed channel 105 and the second feed channel 106 from the surface of the filter screen 120, and then loosens the mounting bolts 43 on the surface of the fixing block 41. The user then pulls the filter screen 120 away from the first extrusion frame 1 and the second extrusion frame 101, causing the filter screen 120 to move the guide block 44. Sliding inside the guide groove 42, the filter screen 120 is guided by the combined action of the guide block 44 and the guide groove 42. At this time, the guide block 44 drives the positioning block 45 away from the inside of the first extruder frame 1 and the second extruder frame 101, so that the filter screen 120 can be removed from the surface of the first extruder frame 1 and the second extruder frame 101 respectively, and the filter screen 120 can be disassembled and cleaned. After cleaning, the first material conveying channel 105 and the second material conveying channel 106 can be assembled on the surface of the filter screen 120 with screws to realize the function of quick disassembly and cleaning of the filter screen 120 by the extruder. This prevents the surface of the filter screen 120 from becoming blocked when the extruder is used, making the extruder more convenient to operate.

[0027] Subsequently, when the electric heater 104 heats the raw materials inside the first extrusion frame 1 and the second extrusion frame 101, the second insulation layer 32 and the first insulation layer 31 inside the cavity 33 work together to achieve better insulation of the inner walls of the first extrusion frame 1 and the second extrusion frame 101, improve energy utilization, and reduce heat loss. Under the action of the heating plate 34, the heating efficiency of the first extrusion frame 1 and the second extrusion frame 101 can be improved, so as to realize the function of efficient heating of the extruder. Thus, when the extruder is in use, the heating efficiency of the electric heater 104 on the first extrusion frame 1 and the second extrusion frame 101 can be improved, further ensuring the quality and stability of the plastic melt, and finally completing the use of the extruder.
