Description
Technical field:
The utility model relates to a kind of tablet press machine, relates in particular to the charging depth adjustment of tablet press machine.
Background technology:
At present, the tablet article are more and more general, and the field of using the tablet thing constantly enlarges, and market increases the demand of tablet thing year by year.And the tablet thing is processed powder or particle with tablet press machine through the high pressure mold pressing.Existing compressing tablet function is pressed into the tablet of different shape with graininess, dusty raw materials, can suppress large product, simultaneously can a mould multi-disc, can be used for large-scale production industry, and die change is easy for installation, easy simple to operate.Existing tablet press machine is as shown in Figure 1; It comprises upper mounted plate 1, upper shifting board 2, center fixed plate 3, lower shifting board 4, bottom plate 5, four guide upright posts 6, go up hydraulic cylinder 7, cope match-plate pattern 8, go up die head 9, hydraulic cylinder 10, lower bolster 11, lower die head 12 and intermediate die plate 13 down; Upper mounted plate 1 is fixed on the upper end of four guide upright posts 6; Bottom plate 5 is fixed on the lower end of four guide upright posts 6, and center fixed plate 3 is fixed on the middle part of four guide upright posts 6, and upper shifting board 2 is sleeved on four guide upright posts 6; And between upper mounted plate 1 and center fixed plate 3; The housing of last hydraulic cylinder 7 is installed on the upper surface of upper mounted plate 1, and is positioned at the center of upper mounted plate 1, and the piston external part of last hydraulic cylinder 7 is fixedly connected with upper shifting board 2; Cope match-plate pattern 8 is fixedly mounted on the lower surface of upper shifting board 2, is provided with die head 9 in the lower surface of cope match-plate pattern 8; Lower shifting board 4 is sleeved on four guide upright posts 6; And between center fixed plate 3 and bottom plate 5; The housing of following hydraulic cylinder 10 is fixedly mounted on the lower surface of bottom plate 5, and is positioned at the center of bottom plate 5, and the piston external part of following hydraulic cylinder 10 is fixedly connected on lower shifting board 4 lower surfaces; Lower bolster 11 is installed on the upper surface of lower shifting board 4, on the upper surface of lower bolster 11, is provided with lower die head 12; Intermediate die plate 13 is installed on center fixed plate 3; On intermediate die plate 13, have the tablet die cavity, last die head 9 is aimed at the tablet die cavity at upper and lower surface respectively with lower die head 12, between last die head 9, tablet die cavity and lower die head 12 threes, forms one and seals complete compressing tablet die cavity; Lower die head 12 is moved in the tablet die cavity of intermediate die plate 13 through following hydraulic cylinder 10 earlier during compressing tablet; According to the operation principle of tablet press machine, generally, the charging degree of depth of tablet is regulated by lower die head 12; Therefore; Before compressing tablet, must regulate the position of lower die head 12 in the tablet die cavity in advance, just want accurately to adjust the spacing between lower shifting board 4 and the bottom plate 5, could guarantee the gauge precision of tablet to be processed like this.Because the stroke adjustment precision of hydraulic jack is very low; Can't satisfy the film-making required precision; Present way is between lower shifting board 4 and bottom plate 5, to place regulating block; Different tablets need be equipped with the regulating block of different-thickness, and the thickness of adjusting will confirm that the tablet of different size need be equipped with corresponding regulating block through several times pressure testing grinding afterwards.A tablet press machine demand is equipped with some secondary regulating blocks, uses very inconvenience, also is easy to because of causing product lot quantity to be scrapped with wrong regulating block.In order to overcome this defective people's utility model has been arranged a kind of bolt and nut component adjusting device, this adjusting device is as shown in Figure 2, and it is made up of three fine-adjusting units; Each fine-adjusting unit is made up of adjusting screw(rod) 21 and adjusting nut 22, on adjusting screw(rod) 21, is provided with rule, and adjusting screw(rod) 21 is screwed in the adjusting nut 22; Change the extension elongation of adjusting screw(rod) 21 through rotation adjusting nut 22, when needs adjustment tablet work loading height, three fine-adjusting units are placed between lower shifting board 4 and the bottom plate 5; Be distributed in piston rod around; And the hand of being convenient to the operator gets at the position of operation, through rotation adjusting nut 22 adjusting screw(rod) 21 is gone up and down then, confirms the exact position of lower shifting board 4 through the rule on the observation adjusting screw(rod) 21; Adjust lower shifting board 4 backs and in the tablet die cavity, put into raw material; Hydraulic cylinder 7 moves down upper shifting board 2 in the startup, and last die head 9 is depressed in the tablet die cavity of intermediate die plate 13, suppresses required tablet.Though this micromatic setting can be realized accurately fine setting, very high to the operation requirement, should correctly put three fine-adjusting units; And to regulate three fine-adjusting units; The more important thing is the uniformity that to guarantee each fine-adjusting unit, otherwise will influence precision that the adjusting workload is big; Very loaded down with trivial details, human factor is very big to the influence of degree of regulation.
The utility model content:
