[0021] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0022] like Figure 1-4 As shown, a double-roller stabilizer tabletting device comprises a support frame 1, two pressing rollers 2, a feed hopper 3 and a scraper guide assembly; the support frame 1 has a corresponding supporting force, and a accommodating space is formed inside for the corresponding tabletting operation, and the bottom is open to discharge the material to the conveying device; here, preferably, one side of the accommodating space is open, so that a belt conveyor can be extended to the bottom of the extrusion channel 4, and the belt conveyor can transport the processed material to the outside. Specifically, one side of the accommodating space is open, so that a belt conveyor can be extended to the bottom of the extrusion channel 4, and the belt conveyor can transport the processed material to the outside.

[0023] The two pressing rollers 2 are rotatably installed in the accommodating space, and the two pressing rollers 2 are connected to a rotation driving assembly through a roller shaft. The rotation driving assembly is arranged outside the supporting frame 1, and the rotation driving assembly is configured to make the two pressing rollers 2 rotate in opposite directions. Specifically, the rotation driving assembly can be one or two rotating motors to provide a rotation driving force to the pressing rollers 2; the gap between the two pressing rollers 2 forms an extrusion channel 4; the feed hopper 3 is fixed at the opening at the upper end of the supporting frame 1 to discharge material into the extrusion channel 4; specifically, a discharge plate 5 is arranged at the bottom of the feed hopper 3, and the discharge plate 5 has a discharge port 6, which is located above the extrusion channel 4, and the discharge ports 6 are arranged at intervals along the length direction of the extrusion channel 4. The material in the feed hopper 3 can be discharged through the discharge ports 6 arranged at intervals along the length direction of the extrusion channel 4, and the contact pressing rollers 2 are distributed along the length direction of the extrusion channel 4 to improve the tableting efficiency.

[0024] In some preferred embodiments, the scraper guide assembly is set as two groups, which are fixedly installed on two opposite inner walls of the accommodating space and are located below the corresponding pressure roller 2, and are used to clean the residual material on the surface of the pressure roller 2. Specifically, the scraper guide assembly includes a support inclined plate 7, a support member 8, an arc plate 9 and an exhaust assembly; one side of the support inclined plate 7 is fixed to the inner wall of the accommodating space and is located obliquely below the corresponding pressure roller 2, and has a corresponding supporting force; the two ends of the support inclined plate 7 extend to the two ends of the length direction of the extrusion channel 4 respectively; the support member 8 is fixed at the two ends of the length direction of the support inclined plate 7, and has a corresponding supporting force; the arc plate 9 is fixed between the top ends of the support members 8 and is coaxial with the pressure roller 2. The working surface of the arc plate 9 is equipped with rubber strips 10, which are arranged in a ring array and arranged at intervals along the length direction of the arc plate 9. The top end contacts the outer surface of the pressure roller 2, and the corresponding cleaning operation is performed when the pressure roller 2 rotates; the exhaust assembly is connected to the arc plate 9, generates airflow and discharges it to the outer surface of the pressure roller 2, and performs corresponding wind sweeping operations;

[0025] It should be noted that a baffle 15 is arranged on the side of the support inclined plate 7 close to the extrusion channel. The baffle 15 can prevent the material cleaned from the extrusion roller from entering the conveying device. At the same time, a certain distance is set between the top of the baffle 15 and the bottom of the pressure roller, so that the material can fall from the extrusion channel to the conveying device.

[0026] In some preferred embodiments, specifically, the exhaust assembly includes an exhaust cavity 11, which is fixedly connected to the arc plate 9 on one side of the inner wall of the accommodating space, an exhaust pipe 12 is arranged on the working surface of the exhaust cavity 11, and an air outlet of the exhaust pipe 12 faces the surface of the corresponding pressure roller 2, and the exhaust cavity 11 is connected to an airflow conveying device, which may be an air pump, a fan, etc., which exhausts air to the corresponding pressure roller 2 through the exhaust pipe 12.

[0027] When in use, the device is placed at a suitable position, the material is received by the feed hopper 3, and the material to be pressed is discharged into the extrusion channel 4 formed between the two pressing rollers 2, and the rotation drive assembly is started to make the two pressing rollers 2 rotate in opposite directions, and the material entering the extrusion channel 4 is squeezed to perform tableting;

[0028] During the rotation of the pressing roller 2, the rubber strip 10 in contact with the side is flexible enough to clean the surface of the pressing roller 2 in contact. At this time, the fan (air flow conveying device) is started to sweep the surface of the pressing roller 2 through the air outlet. Through the above operation, the surface of the pressing roller 2 is cleaned in time to avoid affecting the efficiency of the sheeting.

[0029] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
