[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an extruder for rubber products comprises an extruder body 1; a feed box 11 is connected to the middle of the extruder body 1; a first rotating shaft 12 is connected to the middle of the feed box 11; a servo motor 13 is connected to the end of the first rotating shaft 12; a plurality of eccentric wheels 14 are fixedly connected to the middle of the first rotating shaft 12; a plurality of rectangular notches 15 are provided on the inner walls on both sides of the extruder body 1; a plurality of tension springs 16 are connected to the middle of the rectangular notches 15; a sieve plate 17 is connected to the ends of the tension springs 16; when working, when the raw materials for producing rubber products are poured into the feed box 11, the raw materials will first fall onto the surface of the sieve plate 17, at which time the servo motor 13 can be operated first to drive the first rotating shaft 12 to rotate in the middle of the feed box 11, and the rotation of the first rotating shaft 12 will drive The eccentric wheel 14 rotates, and while rotating, it will support the sieve plate 17, so that the sieve plate 17 will bounce up and down in the middle of the rectangular slot 15. When the sieve plate 17 bounces, the raw materials on its surface can be screened, and at the same time, the tension spring 16 will be stretched by the shaking of the sieve plate 17. In this step, the rotation of the eccentric wheel 14 can drive the sieve plate 17 to screen the raw materials required for the rubber products, so that the raw materials falling into the extruder body 1 can be of the same specification, thereby preventing the uneven flow of materials during the extrusion of the raw materials due to the different sizes of the raw materials, making it difficult to maintain a stable extrusion speed and extrusion volume, resulting in unstable size of the extruded rubber semi-finished products, and even shape deviation, affecting the quality of the finished rubber products.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the side of the material box 11 is fixedly connected with multiple groups of hollow sleeves 2; the middle of the hollow sleeves 2 is slidably connected with a pull rod 21; one end of the pull rod 21 is fixedly connected with a scraper 22; the middle of the scraper 22 is fixedly connected with multiple groups of pillars 23; the ends of the pillars 23 are fixedly connected with a brush plate 24; the other end of the pull rod 21 is fixedly connected with a pull plate 25; when working, the middle of the pull plate 25 can be held and pulled first, so as to drive the pull rod 21 to slide in the middle of the hollow sleeve 2, and the sliding of the pull rod 21 will cause the scraper 22 to drive the raw materials on the surface of the screen plate 17 to move, and at the same time, the pillars 23 and the brush plate 24 will move with the scraper 22 The scraper 22 can push the raw materials on the surface of the sieve plate 17 in this step, so that the unqualified raw materials can be collected in one place. The brush plate 24 can easily cause the sieve plate 17 to be blocked when the size of the raw materials is consistent with the filter holes at the sieve plate 17, thereby affecting the sieve plate 17 to screen the raw materials. At this time, the brush plate 24 can effectively reduce the occurrence of such situations. The hollow sleeve 2 can provide a certain supporting force for the pull rod 21, thereby enhancing the stability of the pull rod 21 when sliding.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, fans 3 are connected to both sides of the discharge box 11; a cross support frame 31 is fixedly connected to the middle of the fan 3; a second shaft 32 is rotatably connected to the middle of the cross support frame 31; a plurality of fan blades 33 are fixedly connected to the middle of the second shaft 32; when working, the cross support frame 31 plays a role of supporting the second shaft 32. When the fan 3 is needed to work, the second shaft 32 can be rotated in the middle of the cross support frame 31 first, and the rotation of the second shaft 32 will drive the fan blades 33 to rotate, thereby forming a certain suction force. This step is because the raw materials are easily contaminated with dust during transportation and storage, and the dust easily affects the quality of rubber products. When the sieve plate 17 shakes the raw materials up and down to screen, dust will be raised. At this time, the dust can be adsorbed by the action of the fan 3, thereby reducing the amount of dust in the raw materials, thereby improving the quality of the finished products produced by the extruder body 1.

[0027] like Figure 2 , Figure 3 As shown, a tamping column 4 is fixedly connected to the middle of the brush plate 24; a baffle 41 is hingedly connected to the side of the discharge box 11; a plurality of sets of hinges 42 are connected to the side of the baffle 41; during operation, when the brush plate 24 moves to a certain position, the tamping column 4 will support the baffle 41, and at this time, the baffle 41 will be forced to expand outward due to the influence of tension and the action of the hinge 42, so that the raw materials brought out by the scraper 22 can be smoothly cleared out of the discharge box 11. In this step, the tamping column 4 and the baffle 41 can be opened to cooperate with the scraper 22 to clean the raw materials out of the outside, thereby preventing unqualified raw materials from accumulating on the surface of the screen plate 17, which may easily affect the subsequent screening of raw materials by the screen plate 17.

[0028] like Figure 1 , Figure 2 As shown, sound-absorbing shutters 5 are connected to both sides of the discharge box 11; a plurality of groups of window leaves 51 are connected to the middle of the sound-absorbing shutters 5; when working, the fan 3 will generate certain noise, and the noise will flow to the sound-absorbing shutters 5 with the wind force. At this time, the noise will generate friction and interference with the window leaves 51, thereby reducing the intensity of the noise. This step can reduce the noise propagation intensity and noise pollution through the mutual cooperation of the sound-absorbing shutters 5 and the window leaves 51, thereby providing a better working environment for the staff.

[0029] like Figure 1 , Figure 2As shown, one side of the discharge box 11 is connected to a collecting box 6; during operation, the raw materials cleaned by the scraper 22 will eventually fall into the collecting box 6 through the baffle 41. In this step, the cleaned raw materials can be collected uniformly through the opening of the collecting box 6, thereby preventing the raw materials from being easily scattered when cleaned, resulting in the need for secondary cleaning.

[0030] like Figure 1 , Figure 2 , Figure 4 As shown, an arc-shaped limit plate 7 is fixedly connected to one side of the discharge box 11; when working, the arc-shaped limit plate 7 can support the servo motor 13. This step can improve the stability of the servo motor 13 through the arc-shaped limit plate 7, thereby preventing the servo motor 13 from shaking easily during operation, thereby affecting the screening efficiency of the screen plate 17.

[0031] Working principle: during operation, when the raw materials for producing rubber products are poured into the feed box 11, the raw materials will first fall onto the surface of the sieve plate 17. At this time, the servo motor 13 can be operated to drive the first rotating shaft 12 to rotate in the middle of the feed box 11. The rotation of the first rotating shaft 12 will drive the eccentric wheel 14 to rotate, and the eccentric wheel 14 will support the sieve plate 17 while rotating, so that the sieve plate 17 will be shaken up and down in the middle of the rectangular notch 15. When the sieve plate 17 shakes, the raw materials on its surface can be screened. At the same time, the stretching spring 16 will be stretched by the shaking of the sieve plate 17. In this step, the rotation of the eccentric wheel 14 can drive the sieve plate 17 to screen the raw materials required for rubber products, so that the raw materials can fall onto the extruder body 1 The raw materials inside are of the same specification, so as to prevent uneven material flow during the extrusion of raw materials due to different sizes, making it difficult to maintain stable extrusion speed and extrusion volume, resulting in unstable size of the extruded rubber semi-finished products, and even shape deviation, affecting the quality of the finished rubber products. When working, you can first hold the middle of the pull plate 25 and pull it to drive the pull rod 21 to slide in the middle of the hollow sleeve 2. The sliding of the pull rod 21 will cause the scraper 22 to drive the raw materials on the surface of the screen plate 17 to move. At the same time, the support 23 and the brush plate 24 will move with the movement of the scraper 22, so that the surface of the screen plate 17 can be cleaned. In this step, the scraper 22 can push the raw materials on the surface of the screen plate 17, so that unqualified The raw materials are collected in one place. The role of the brush plate 24 is that when the size of the raw materials is consistent with the filter holes on the sieve plate 17, the sieve plate 17 is likely to be blocked, thereby affecting the sieve plate 17 from screening the raw materials. At this time, the brush plate 24 can effectively reduce the occurrence of such situations. The hollow sleeve 2 can provide a certain supporting force for the pull rod 21 to enhance the stability of the pull rod 21 when sliding. When working, the cross support frame 31 plays a role in supporting the second rotating shaft 32. When the fan 3 is needed to work, the second rotating shaft 32 can be rotated in the middle of the cross support frame 31 first, and the rotation of the second rotating shaft 32 will drive the fan blades 33 to rotate, thereby forming a certain suction force. This step is As raw materials are easily contaminated with dust during transportation and storage, and dust easily affects the quality of rubber products, when the screen plate 17 is moved up and down to screen the raw materials, dust will be raised. At this time, the dust can be adsorbed by the fan 3, thereby reducing the amount of dust in the raw materials, thereby improving the quality of the finished products produced by the extruder body 1. During operation, when the brush plate 24 moves to a certain position, the tamping column 4 will support the baffle 41. At this time, the baffle 41 will be forced to expand outward due to the influence of tension and the action of the hinge 42, so that the raw materials brought out by the scraper 22 can be smoothly cleared out of the discharge box 11. In this step, the tamping column 4 and the baffle 41 are opened, and the scraper 22 can be used to clean the raw materials out of the outside, thereby preventing unqualified raw materials from accumulating on the surface of the screen plate 17.It is easy to affect the screening work of the subsequent raw materials by the sieve plate 17. When working, the fan 3 will generate a certain amount of noise. At this time, the noise will flow to the sound-absorbing shutter 5 with the wind force. At this time, the noise will produce friction and interference with the window leaf 51, thereby reducing the intensity of the noise. This step can reduce the transmission intensity and noise pollution of noise through the mutual cooperation of the sound-absorbing shutter 5 and the window leaf 51, thereby providing a better working environment for the staff. When working, the raw materials cleaned by the scraper 22 will eventually fall into the collection box 6 through the baffle 41. This step can collect the cleaned raw materials uniformly through the opening of the collection box 6, thereby preventing the raw materials from being easily scattered when they are cleaned out, resulting in the need for secondary cleaning. When working, the arc-shaped limit plate 7 can play the role of supporting the servo motor 13. This step can improve the stability of the servo motor 13 through the arc-shaped limit plate 7, thereby preventing the servo motor 13 from easily shaking during work and affecting the screening efficiency of the sieve plate 17.
