Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the invention. It should be noted that, for convenience of description, only the parts related to the present invention are shown in the drawings.

In the present invention, the embodiments and the features of the embodiments may be combined with each other without conflict. The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1, the present invention provides a dust suction mechanism 2 for a tablet press machine 1.

Referring to fig. 2, the sheeter dust suction mechanism 2 comprises a vacuum suction part 21. The negative pressure cleaner 21 includes a main body, and a first cleaner 211 and a second cleaner 212 projecting outward along the main body.

The first and second

dust suction parts

211 and 212 have a vertical thickness. Thereby increasing the area in the vicinity of the mold. When the first dust suction part 211 is provided with a first air suction port 215 in the vertical direction on the side facing the die plate of the tablet press machine 1, and the second dust suction part 212 is provided with a second air suction port 216 in the vertical direction on the side facing the die plate of the tablet press machine 1, the whole die on the die plate is expected to be in the dust suction range of the dust suction mechanism 2 of the tablet press machine, so that the mechanism can fully absorb pollutants.

Referring to fig. 3, the first side of the body is provided with a device interface 210 for communicating with a negative pressure device. The device interface 210 is connected to a negative pressure device, including but not limited to the following: screw connection, clamping connection and flange connection. The body is rectangular, and a cavity is arranged in the body, and the cavity is connected with the equipment interface 210, the first air suction port 215 and the second air suction port 216, so that negative pressure is provided for the first air suction port 215 and the second air suction port 216.

The first dust suction part 211 and the second dust suction part 212 are arranged at intervals, so that a groove structure is formed between the first dust suction part 211 and the second dust suction part 212, the first dust suction part 211 and the second dust suction part 212 can extend towards the interior of the mold disc along the upper surface and the lower surface of the mold sheet and are close to the mold, and the first dust suction part 211 and the second dust suction part 212 can effectively apply suction to the mold set. Meanwhile, it is noted that contaminants are generated not only with the surface of the mold but also with the surface of the mold tray, and thus a third suction port 217 in a vertical direction is provided at a body portion spaced between the first dust suction part 211 and the second dust suction part 212, and the third suction port 217 is also communicated with the device interface 210, thereby obtaining a suction force.

It is anticipated that contaminants will stay on the upper side of the mold plate due to support from the mold plate and on the sides of the mold plate due to adhesion. On the underside of the mould disc, however, the contaminants tend to fall out to the downwardly facing surface of the mould disc due to their own weight. And dust generated during tabletting has a tendency to scatter downwards. The lower side of the mold platen has fewer contaminants that collect on the upper side surface of the mold platen and the surface of the platform that is used to support the mold platen. Therefore, the lower side of the first dust suction part 211 is provided with the fourth suction port 218, and the lower side of the second dust suction part 212 is provided with the fifth suction port 219, so that the dust removing requirement for the above surface is satisfied.

In the process of installing the negative pressure dust suction part 21, it is necessary to ensure that the first dust suction part 211 and the second dust suction part 212 can extend into the space between the dust suction disc and the upper side mechanism for supporting the mold disc and the pressing die, and a certain distance is ensured to be kept between the first dust suction part and the second dust suction part, so that a larger suction force is realized on the premise that the work of the mold disc and the like is not influenced. The first thickness 31 of the first dust absorption part 211 is 35mm-45 mm; the second thickness 32 of the second dust suction part 212 is 16mm-18 mm; the bottom of the first dust suction part 211 is at a first height 33 from the top of the second dust suction part 212, and the first height 33 is 40mm-44 mm. The lower side of the first dust suction part 211 is at a second height 34 from the surface supporting the mould disc, said second height 34 being 76mm-80 mm. The first dust suction part 211 and the second dust suction part 212 have the same extension length 35, the extension length 35 is a distance between a side surface of the first dust suction part 211 or the second dust suction part 212 facing the die plate of the tablet press machine 1 and a side surface of the body facing the die plate of the tablet press machine 1, and the extension length 35 is 45mm to 55 mm.

Further, the negative pressure dust collecting part 21 further includes a base 213 disposed at the lower portion of the main body, and the base 213 is provided with a plurality of mounting holes 214. The vacuum suction part 21 is mounted on the surface of the tablet press machine 1 supporting the die plate through the above mounting hole 214. The second height 34 is also the distance of the lower side of the first dust collecting part 211 from the lower side of the base 213. The thickness of the base 213 is 3mm-5mm, which can meet the strength design requirement.

Referring to fig. 2, the dust suction mechanism 2 of the tablet press machine further includes a positive pressure dust removing part 22. Since the vertical opening of the negative pressure dust suction part 21 is substantially provided with the negative pressure opening, the three-dimensional space around the negative pressure opening is filled with the positive pressure, and thus the air pressure around the negative pressure opening is reduced with a substantially equal gradient. The negative pressure opening exerts less force on the farther mold surface. Part of the pollutants or oil with higher viscosity can not fall off under the action of the negative pressure air suction port. However, the positive pressure dust removing part 22 can achieve the effect of dropping off the pollutants or oil with high viscosity under the same power. Since the positive pressure dust removing part 22 ejects the gas in a high speed gas flow manner, substantially accelerates the gas molecules in the pipeline, and the gas molecules collide with the gas molecules in the air after being separated from the pipeline, so that the power is weakened, and it is expected that the acting force of the gas molecules ejected at the positive pressure on the pollutants is larger than that generated by the negative pressure on the advancing path of the gas if the distance is equal. Therefore, the dust suction mechanism 2 of the tablet press machine increases the arrangement of the positive pressure dust removal part 22.

Meanwhile, it is considered that the positive pressure dust removing part 22 may cause serious pollution to the material if the pollutant falls into the material in the mold after the pollutant is separated. Therefore, it is necessary to ensure that contaminants are sucked by the vacuum suction part 21 immediately after being blown off from the mold surface. The utility model discloses with malleation dust removal portion 22 with negative pressure dust absorption portion 21 sets up side by side to refer to fig. 1-3, the side that is provided with equipment interface 210 with negative pressure dust absorption portion 21 is called first side, and the side that deviates from negative pressure dust absorption portion 21 to be provided with equipment interface 210 is called the second side, sets up on this second side malleation dust removal portion 22, the mould dish of tablet press 1 is rotatory to the direction of first side from the second side of negative pressure dust absorption portion 21. Thus, the contaminants adhered to the mold are scattered or loosened by the force of the positive pressure dust removing part 22. The molds are rotated to the action range of the negative pressure dust suction part 21 by the mold disc, and scattered or loosened pollutants can be captured by the negative pressure dust suction part 21 in time. And the blowing port of the positive pressure dust removing part 22 and the suction port of the negative pressure dust removing part 21 need to have strict relative distance and posture control. In a preferred embodiment, the distance between the blowing port of the positive pressure dust removing part 22 and the first air inlet 215 or the second air inlet 216 is not more than 100mm, and the blowing direction of the blowing port is deviated to the dust suction direction of the negative pressure dust removing part 21, so that pollutants blown off by the blowing port fall into the influence range of the negative pressure dust removing part 21, and the pollutants are ensured to be accurately absorbed.

Further, a mounting seat 23 is also included. The positive pressure dust removal part 22 comprises an elongated spray pipe and a positive pressure input part positioned at the tail end of the spray pipe; the mounting seat 23 faces the side face of the body is provided with a mounting groove for placing the slender spray pipe, the mounting seat 23 is further provided with threaded holes located on two sides of the mounting groove, and the mounting seat 23 is fixedly connected with the body through the threaded holes. The elongate lance is sandwiched between the body and the mounting 23. The axis of symmetry of the mounting base 23 is at the same height as the centerline of the second dust suction portion 212. The elongated nozzle terminates in a nozzle which is inclined in the direction of the second suction portion 212.
