Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion equipment technology, and in particular to an extrusion equipment for processing plastic profiles. Background Technology
[0002] The extrusion equipment for processing plastic profiles is a complete set of equipment specifically designed to extrude plastic raw materials into products with specific cross-sectional shapes after heating, melting, and pressurizing them. It is the core of plastic profile production, enabling continuous processing from raw materials to finished products, and features both high efficiency and customizable shapes.
[0003] When using an extrusion device for processing plastic profiles to manufacture plastic profiles, plastic granules need to be continuously fed into the feed hopper. Some plastic granules may accumulate at the bottom of the feed hopper, forming a relatively compact whole. This can cause blockage at the bottom of the feed hopper, making it difficult for the plastic granules to enter the hot melt tube normally, which will reduce the efficiency of plastic extrusion. Utility Model Content
[0004] This invention provides an extrusion device for processing plastic profiles to address the problem that some plastic particles may clog the bottom of the feed hopper, making it difficult for the plastic particles to enter the hot melt tube normally, which would reduce the efficiency of plastic extrusion.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an extrusion device for processing plastic profiles, comprising a frame, a side plate welded to one side of the frame, a plurality of hot melt tubes uniformly installed on one side of the side plate, a feed hopper fixedly installed at one end of the outer surface of each hot melt tube, a connecting pipe welded to the other end of the outer surface of two hot melt tubes that are far apart, one end of the outer surface of the hot melt tube located in the middle position being fixedly connected to one end of each of the two connecting pipes, and a shaped die fixedly installed at one end of the hot melt tube, and an auxiliary device provided on one side of each of the three feed hoppers, the auxiliary device using a striking plate to strike the three feed hoppers, causing the accumulated plastic particles to enter the hot melt tubes.
[0006] The effect achieved by the above components is as follows: by setting up and adjusting the striking plate, the striking plate strikes the three feed hoppers, which causes the feed hoppers to vibrate. The vibration of the feed hoppers will cause the accumulated plastic particles to separate and enter the hot melt tube, which helps to prevent the plastic particles from clogging the bottom of the feed hopper and causing a decrease in plastic extrusion efficiency.
[0007] Preferably, the auxiliary device includes a striking plate, which is disposed on one side of the three feed hoppers. Springs are symmetrically installed on one side of the striking plate, and an extension plate is fixedly installed at one end of each spring. One end of each of the two extension plates is symmetrically fixedly installed on one side of the top of the side plate, and a wire is fixedly installed in the middle of one side of the striking plate.
[0008] The effect achieved by the above components is as follows: pulling the conveyor belt causes the striking plate to move away from the three feed hoppers. The striking plate compresses the spring, causing it to deform until the striking plate reaches the appropriate position. Then, the force applied to the conveyor belt is removed, and the spring returns to its original position, causing the striking plate to move towards the three feed hoppers. This causes the striking plate to strike the three feed hoppers, which vibrates the three feed hoppers and helps the plastic particles blocking the bottom of the feed hoppers to enter the hot melt tube.
[0009] Preferably, the spring has a round rod inside, one end of which is fixedly installed on one side of the striking plate, and the round rod is slidably installed on the inner wall of the extension plate.
[0010] The effect achieved by the above components is that by setting the round rod, the round rod can guide the spring and the striking plate, making the striking plate more stable during movement, and also helping to prevent the spring from bending during deformation.
[0011] Preferably, a silicone plate is fixedly installed on one side of the tapping plate near the three feed hoppers, and three grooves that are adapted to the outer surface of the feed hoppers are evenly opened on one side of the silicone plate.
[0012] The effect achieved by the above-mentioned components is that by setting a silicone plate with grooves, one side of the plate can be replaced by the impact plate and abut against the outer surface of the feed hopper, which can play a certain protective role for the feed hopper and help prevent the impact plate from excessively hitting the feed hopper and causing damage to the feed hopper.
[0013] Preferably, a bracket is installed at the center of the top of the side plate, a fixed pulley is rotatably installed on the inner wall of the bracket, the line is disposed on the outer surface of the fixed pulley, the same limiting block is fixedly installed on one side of the bracket and the side plate, and one end of the line passes through the inner wall of the limiting block.
[0014] The effect achieved by the above components is that by setting fixed pulleys and limiting blocks, the direction of the force required to pull the line can be changed, so that when the line is pulled vertically, the striking plate can be moved horizontally, making it easier to adjust the striking plate.
[0015] Preferably, one end of the line passes through the inner wall of the limiting block and is fixedly mounted with a handle.
[0016] The effect achieved by the above components is as follows: by setting up a grip, it is easy to pull the line through the grip, and at the same time, the grip can block one end of the line, which helps to prevent the line from detaching from the limit block and the fixed pulley under the action of the spring.
[0017] Preferably, an L-shaped plate is fixedly installed at the center of the bottom of the striking plate, and bolts are threaded into the inner wall of the L-shaped plate.
[0018] The effect achieved by the above components is as follows: when the striking plate moves on the top of the side plate, it will drive the L-shaped plate to move on the top of the side plate. Then, by rotating the bolt, one end of the bolt passes through the inner wall of the L-shaped plate until one end of the bolt abuts against the top of the side plate. The bolt can fix the striking plate and the top of the side plate, which helps to prevent the striking plate from easily shifting under the action of external force and affecting the normal operation of the feed hopper.
[0019] Preferably, a rubber sheet is adhered to the inner wall of the top of the side plate, and the bolt is located on the top of the rubber strip.
[0020] The effect achieved by the above components is that by setting up a rubber plate, the top of the side plate can be replaced to abut against one end of the bolt, and the friction between the bolts can be increased, making the bolts more firmly fixed to the striking plate.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting a striking plate and adjusting the striking plate so that it strikes the three feed hoppers, the feed hoppers vibrate. This vibration causes the accumulated plastic particles to separate and enter the hot melt tube, which helps to prevent the plastic particles from clogging the bottom of the feed hopper and reducing the plastic extrusion efficiency.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses an extrusion device for processing plastic profiles, including a frame 1. A side plate 2 is welded to one side of the frame 1. A plurality of hot melt tubes 4 are evenly installed on one side of the side plate 2. A feed hopper 3 is fixedly installed at one end of the outer surface of each hot melt tube 4. A connecting pipe 5 is welded to the other end of the outer surface of two distant hot melt tubes 4. One end of the outer surface of the hot melt tube 4 located in the middle position is fixedly connected to one end of each of the two connecting pipes 5, and a shaped die 6 is fixedly installed at one end of the hot melt tube 4. An auxiliary device 7 is provided on one side of each of the three feed hoppers 3. The auxiliary device 7 uses a tapping plate 71 to tap the three feed hoppers 3, causing the accumulated plastic particles to enter the hot melt tube 4. By setting the tapping plate 71 and adjusting it, the tapping plate 71 can strike the three feed hoppers 3, which will cause the feed hoppers 3 to vibrate. The vibration of the feed hoppers 3 will cause the accumulated plastic particles to separate and enter the hot melt tube 4. This helps to prevent the plastic particles from clogging the bottom of the feed hoppers 3, which would reduce the plastic extrusion efficiency.
[0029] Reference Figures 2-4As shown, the auxiliary device 7 includes a striking plate 71, which is disposed on one side of the three feed hoppers 3. Springs 72 are symmetrically mounted on one side of the striking plate 71. An extension plate 73 is fixedly mounted to one end of each spring 72. One end of each extension plate 73 is symmetrically fixedly mounted to one side of the top of the side plate 2. A wire 74 is fixedly mounted in the middle of one side of the striking plate 71. Pulling the wire 74 causes it to move the striking plate 71 away from the three feed hoppers 3. The striking plate 71 compresses the springs 72, causing them to deform until the striking plate 71 reaches a suitable position. Then, the force applied to the wire 74 is removed, and the springs 72 return to their original position. The striking plate 71 moves towards the three feed hoppers 3, causing the striking plate 71 to strike the three feed hoppers 3. This causes the three feed hoppers 3 to vibrate, which can promote the plastic particles blocking the bottom of the feed hoppers 3 to enter the hot melt pipe 4. The spring 72 is provided with a round rod 75 inside. One end of the round rod 75 is fixedly installed on one side of the striking plate 71. The round rod 75 is slidably installed on the inner wall of the extension plate 73. By setting the round rod 75, the round rod 75 can guide the spring 72 and the striking plate 71, making the striking plate 71 more stable during movement and also helping to prevent the spring 72 from bending during deformation.
[0030] Reference Figures 2-4 As shown, a silicone plate 76 is fixedly installed on one side of the striking plate 71 near the three feed hoppers 3. Three grooves matching the outer surface of the feed hoppers 3 are evenly distributed on one side of the silicone plate 76. By providing the grooved silicone plate 76, it can replace one side of the striking plate 71 in contact with the outer surface of the feed hoppers 3, thus providing some protection for the feed hoppers 3 and preventing excessive impact from the striking plate 71 that could damage them. A bracket 79 is installed in the middle of the top of the side plate 2. A fixed pulley 78 is rotatably installed on the inner wall of bracket 79, and the cable 74 is set on the outer surface of the fixed pulley 78. The same limiting block 77 is fixedly installed on one side of bracket 79 and side plate 2. One end of cable 74 passes through the inner wall of limiting block 77. By setting fixed pulley 78 and limiting block 77, the direction of the force required to pull cable 74 can be changed, so that when cable 74 is pulled vertically, the striking plate 71 can be driven to move horizontally, making it easier to adjust striking plate 71.
[0031] Reference Figure 2 and Figure 4 As shown, one end of the line 74 passes through the inner wall of the limiting block 77 and is fixedly installed with a handle 710. By setting the handle 710, it is easy to pull the line 74 through the handle 710. At the same time, the handle 710 can block one end of the line 74, which helps to prevent the line 74 from detaching from the limiting block 77 and the fixed pulley 78 under the action of the spring 72.
[0032] Reference Figure 2 and Figure 4 As shown, an L-shaped plate 711 is fixedly installed at the center of the bottom of the striking plate 71. A bolt 712 is threaded into the inner wall of the L-shaped plate 711. When the striking plate 71 moves on the top of the side plate 2, it will drive the L-shaped plate 711 to move on the top of the side plate 2. Then, the bolt 712 is rotated so that one end of the bolt 712 passes through the inner wall of the L-shaped plate 711 until one end of the bolt 712 abuts against the top of the side plate 2. The bolt 712 can fix the striking plate 71 and the top of the side plate 2, which helps to prevent the striking plate 71 from easily shifting under the action of external force and affecting the normal operation of the feed hopper 3. A rubber plate 713 is glued to the inner wall of the top of the side plate 2. The bolt 712 is set on the top of the rubber plate. By setting the rubber plate 713, it can replace the top of the side plate 2 to abut against one end of the bolt 712 and increase the friction between the bolts 712, making the bolt 712 fix the striking plate 71 more firmly.
[0033] Working principle: Pulling the handle 710 causes the line 74 to move vertically. Under the action of the fixed pulley 78, the line 74 moves the striking plate 71 away from the three feed hoppers 3. The striking plate 71 compresses the spring 72, causing it to deform until it reaches the appropriate position. Then, the force applied to the handle 710 is released, and the spring 72 returns to its original position, moving the striking plate 71 back towards the three feed hoppers 3. This causes the silicone plate 76 on one side of the striking plate 71 to strike the three feed hoppers 3, resulting in… The vibration of the three feed hoppers 3 can cause the plastic particles blocking the bottom of the feed hoppers 3 to enter the hot melt pipe 4. When the striking plate 71 moves on the top of the side plate 2, it will drive the L-shaped plate 711 to move on the top of the side plate 2. Then, the bolt 712 is rotated so that one end of the bolt 712 passes through the inner wall of the L-shaped plate 711 until one end of the bolt 712 abuts against the rubber plate 713 on the top of the side plate 2. The bolt 712 can fix the striking plate 71 and the top of the side plate 2, which helps to prevent the striking plate 71 from easily shifting under the action of external force and affecting the normal operation of the feed hopper 3.
