DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] In order to solve the technical problem of limited overall cleaning effect, the utility model provides a rubber extruder capable of achieving better cleaning effect.

[0029] It should be noted that the rubber extruder described in the present invention is used for but not limited to rubber, etc. For the convenience of explanation, in the present invention, only an example of a rubber extruder applied to rubber extrusion equipment is used for explanation. The principle of a rubber extruder applied to other types of equipment is substantially the same as the principle applied to rubber extrusion equipment, which will not be repeated here.

[0030] See also Figure 1 - Figure 7 ,in Figure 1This is a structural schematic diagram of a rubber extruder in an embodiment of the utility model, a rubber extruder comprises a barrel 100, a feed hopper 200, an extrusion mechanism 300 and an extrusion disc 400; a mounting port 110 and a discharge port 120 are respectively provided on both sides of the barrel 100; the feed hopper 200 is detachably connected to the mounting port 110; the extrusion mechanism 300 comprises a screw 310 and a driving member 320, the screw 310 is arranged in the barrel 100, the driving member 320 is arranged on one side of the barrel 100 and is connected to the screw 310 in a transmission manner; the extrusion disc 400 is detachably connected to the discharge port 120, and an extrusion hole 410 is provided in the center of the extrusion disc 400.

[0031] In the present embodiment, by detachably connecting the feed hopper 200 with the mounting port 110 and arranging the screw 310 on the barrel 100, the disassembly of the screw 310 is more convenient, which is beneficial to the thorough cleaning of the screw 310; further, the cleaning agent can also be quickly introduced through the mounting port 110 to achieve a faster and more thorough cleaning effect; in addition, since the extrusion disk 400 and the discharge port 120 are detachably connected, the extrusion disk 400 is easy to disassemble for cleaning, and due to the disk-shaped structure of the extrusion disk 400, the hole depth of the extrusion hole 410 is limited, that is, the inner wall surface area that needs to be cleaned is smaller, which is easier to clean, that is, the overall cleaning effect is effectively improved.

[0032] In one embodiment, see Figure 1 , Figure 2 , Figure 4 The extrusion disc 400 is threadedly connected to the discharge port 120 .

[0033] In this embodiment, the threaded connection between the extrusion disc 400 and the discharge port 120 can make the extrusion disc 400 easier to disassemble; specifically, the extrusion disc 400 can be quickly disassembled and assembled by an electric screwdriver.

[0034] In one embodiment, see Figure 1 , Figure 4 The installation opening 110 is opened on one side of the outer wall of the cylinder 100, and the opening arc of the installation opening 110 is at least 180°.

[0035] In this embodiment, the large arc design of the mounting opening 110 makes the disassembly and assembly of the screw rod 310 more convenient, and also facilitates the use of a detergent and a brush to clean a part of the screw rod 310 without disassembling the screw rod 310 .

[0036] In one embodiment, see Figure 1 , Figure 2 , Figure 4 , Figure 5A material distribution disc 500 is detachably connected to one side of the extrusion disc 400 away from the discharge port 120 . A plurality of material distribution holes 510 are evenly formed on the material distribution disc 500 . The plurality of material distribution holes 510 are connected to the extrusion hole 410 .

[0037] In this embodiment, the structural design of the material distribution hole 510 allows the rubber to be discharged from multiple paths, thereby improving the discharge efficiency; in addition, the design of the material distribution hole 510 can also allow the rubber to be prepared into different specifications, thereby improving practicality.

[0038] In one embodiment, see Figure 2 , Figure 5 , Figure 6 A material storage trough 520 is provided on one side of the material distribution disc 500 close to the extrusion disc 400 , and the bottom of the material storage trough 520 is connected to the material distribution hole 510 .

[0039] In this embodiment, the storage tank 520 is convenient for temporarily storing plastic particles.

[0040] In one embodiment, see Figure 2 , Figure 6 The diameter of the storage tank 520 is at least four fifths of the diameter of the extrusion disk 400 .

[0041] In this embodiment, the diameter design of the storage tank 520 can facilitate the design of more material distribution holes 510.

[0042] In one embodiment, see Figure 2 The wall thickness of the extrusion disk 400 is the same as the wall thickness of the distribution disk 500 .

[0043] In this embodiment, the same design of wall thickness can enable faster preparation and discharge of plastic particles, and facilitate cleaning of the extrusion disk 400 and the distribution disk 500 .

[0044] In one embodiment, see Figure 1 A bracket 600 is provided at the bottom end of the cylinder 100 , and the bracket 600 is used to erect the cylinder 100 .

[0045] In this embodiment, the bracket 600 is convenient for increasing the height of the barrel 100 and providing more expandability for the extruder.

[0046] In one embodiment, see Figure 1 , the bracket 600 is a frame structure.

[0047] In this embodiment, the frame structure is helpful to provide stability.

[0048] In one embodiment, see Figure 1The driving member 320 is a motor 321 , the output end of the motor 321 is transmission-connected with a pulley 700 , and the driven end 710 of the pulley 700 is fixedly connected to the screw rod 310 .

[0049] In this embodiment, the motor 321 drives the pulley 700 and drives the screw 310 to rotate, thereby forcing the plastic particles to move forward in the barrel 100, and finally completing the subsequent heating, shaping and extrusion through shear force and extrusion.

[0050] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the utility model is described in detail:

[0051] When the rubber extruder is used, first, the plastic particles need to be poured in through the feed hopper 200, and the plastic particles are allowed to enter the barrel 100 through the installation port 110; then, the motor 321 drives the pulley 700 to rotate and allows the screw 310 to push and squeeze the plastic particles to move forward; then, the plastic particles complete the subsequent heating and molding and extrusion and feeding in the process of moving forward; specifically, in the extrusion and feeding link, they are extruded through the distribution holes 510 of the distribution plate 500. Since the installation port 110 and the feed hopper 200 are detachably connected, the disassembly of the screw 310 is more convenient, and the screw 310 is convenient for more thorough cleaning; in addition, since the distribution plate 500 and the extrusion plate 400 are both disc-shaped structures, the hole depth of the distribution plate 500 and the extrusion plate 400 is smaller, which is easier to clean, that is, the overall cleaning effect is effectively improved.

[0052] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model.
