[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, a cement roller pressing device includes a connecting box 1, on which a roller pressing structure 6 is provided. A cover plate 2 is detachably connected to the top of the connecting box 1 via multiple bolts. A dust removal structure 3 is provided on the cover plate 2. The dust removal structure 3 includes a dust removal box 301 and a connecting cover 302. The dust removal box 301 is fixedly connected to the cover plate 2. An outer frame 304 is engaged with the dust removal box 301. A filter screen 305 is fixedly connected to the outer frame 304. The top of the dust collector 301 is engaged with the connecting cover 302. Two fans 303 are installed on the connecting cover 302. A dust collection box 306 is engaged inside the dust collection box 301. Four positioning posts 308 are fixedly connected to the dust collection box 301. The positioning posts 308 penetrate the connecting cover 302. A knob 309 is threaded onto the positioning posts 308. A suction pipe 310 is fixedly connected to the dust collection box 301. One end of the suction pipe 310 extends into the interior of the connecting box 1.
[0025] As a technical optimization solution of this utility model, such as Figure 2 and Figure 7 As shown, the top section of the positioning post 308 has a trapezoidal structure, and the knob 309 abuts against the connecting cover 302, thus playing a guiding role when the knob 309 is threadedly connected to the positioning post 308.
[0026] As a technical optimization solution of this utility model, such as Figure 5 and Figure 6 As shown, the suction pipe 310 is fixedly connected to the connecting box 1, and the dust collection box 306 is fixedly connected to the connecting post 307, so the dust collection box 306 can be easily moved by holding the connecting post 307.
[0027] As a technical optimization solution of this utility model, such as Figure 1 As shown, a feed hopper 4 is fixedly connected to the cover plate 2, and a support base 5 is fixedly connected to the bottom of the connecting box 1, so the connecting box 1 can be supported by the support base 5.
[0028] As a technical optimization solution of this utility model, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the roller pressing structure 6 includes a guide seat 601 and a slide seat 602. Two guide seats 601 are fixedly connected to both sides of the connecting box 1. One guide seat 601 is slidably connected to one side of the two slide seats 602, and the other guide seat 601 is slidably connected to the other side of the two slide seats 602. A pressure roller 603 is rotatably connected to the slide seat 602. A support plate 604 is fixedly connected to the slide seat 602. A first motor 605 is mounted on the support plate 604. The output shaft of the first motor 605 is fixedly connected to one end of the pressure roller 603. Therefore, the material can be pressed by the relative rotation of the two pressure rollers 603.
[0029] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, two lead screws 607 are rotatably connected to the support base 5. Both lead screws 607 are threadedly connected to two slides 602. A second motor 606 is installed on the support base 5. The output shaft of the second motor 606 is fixedly connected to one end of the lead screw 607. The cross-section of the end of the slide 602 is L-shaped. The threads at both ends of the lead screw 607 are in opposite directions. Therefore, the distance between the two pressure rollers 603 can be adjusted according to the actual situation.
[0030] As a technical optimization solution of this utility model, such as Figure 4 and Figure 5 As shown, a feeding hopper 7 is fixedly connected to the bottom of the connecting box 1. The top of the feeding hopper 7 has a conical cross-section, so it can guide the material after rolling through the feeding hopper 7.
[0031] In use, material can enter the connecting box 1 from the feed hopper 4. The simultaneous rotation of the output shafts of the two first motors 605 drives the two pressure rollers 603 to rotate relative to each other. This relative rotation of the two pressure rollers 603 compresses the material located between them. The compressed material falls through the gap between the two pressure rollers 603 into the discharge hopper 7. When the distance between the two pressure rollers 603 needs to be adjusted according to actual conditions, the two second motors 606 can be started simultaneously, causing their output shafts to rotate. The screw 607 rotates, and the simultaneous rotation of both screws 607 causes the two slides 602 to move in opposite directions. The guide seat 601 guides the movement of the slides 602. The opposite movement of the two slides 602 causes the two pressure rollers 603 to move in opposite directions, thus changing the distance between the two pressure rollers 603. This allows for adjustment of the distance between the two pressure rollers 603 according to actual conditions, effectively improving the flexibility of use. During feeding, the two blowers 303 can be activated. The dust generated by the action of 3 will enter the suction pipe 310 with the airflow, and then enter the dust collection box 301. When the air passes through the filter screen 305, the dust will be filtered by the filter screen 305 and fall into the dust collection box 306 for collection. The filtered air will be discharged from one end of the fan 303, thus avoiding the dust generated during the feeding process from being scattered into the air and causing environmental pollution, effectively improving the environmental friendliness of the use. When it is necessary to clean the filter screen 305, it can be done by turning the four knobs 309 in sequence. When all four knobs 309 are in the set position... After unscrewing the position column 308, the connecting cover 302 can be removed from the top of the dust collection box 301. After removing the connecting cover 302, the outer frame 304 and the filter screen 305 can be removed. After removing the filter screen 305, it is convenient to clean the dust accumulated on its surface. Regular cleaning of the filter screen 305 can prevent a lot of dust from adhering to its surface and reducing the dust removal effect. Also, after removing the filter screen 305, it will not block the dust collection box 306, so it is also convenient to remove the dust collection box 306 from the inside of the dust collection box 301. After removal, it is convenient to empty the dust collected inside.
