Description

Technical Field

[0001] The utility model belongs to the technical field of rotary tablet presses, in particular to a rotary tablet press with an adjusting function. Background Technique

[0002] A rotary tablet press is a machine that presses granular materials into tablets by multiple pairs of punching dies evenly distributed on a turntable moving in a circular motion along a certain track. It is mostly used as a pharmaceutical equipment in the process of drug processing. Most rotary tablet presses need to be used in cooperation with a drug delivery mechanism arranged on one side of it. The drug delivery mechanism inputs raw materials into the tablet press, and then the tablet press performs the pressing operation. In Chinese Patent No. CN215512408U, a rotary tablet press with a limiting function for western medicine preparation and production is disclosed, including a rotary tablet press body. A turntable is arranged on the top of the rotary tablet press body, and a conical funnel is arranged on the top of the rotary tablet press body and on the right side of the turntable. In the utility model, by moving the dial, the moving plate is moved to the right, so that the clamping rod disengages from the inside of the clamping groove. Under the action of the second spring, the connecting plate and the inserting rod are always in a squeezed state. When the clamping rod moves to the left to a certain extent and the jack is located at the bottom of the inserting rod, the inserting rod will quickly snap into the inside of the jack to fix the clamping rod and prevent the clamping rod from snapping into the inside of the clamping groove again, completing the limiting of the clamping rod, so as to achieve the purpose of facilitating the limiting of the turntable. At the same time, it solves the problem that the existing rotary tablet press does not have the function of limiting the turntable. When repairing and maintaining the turntable, the turntable is easy to rotate, which is inconvenient for maintenance. Although the existing technology solves the problem of turntable limiting, it does not set an adjusting mechanism to adjust the position of the conical funnel. When the turntable is repaired, the conical funnel at a fixed position will also block the repair of the turntable. And the conical funnel at a fixed position will also cause, to a certain extent, that after all the medicine grooves on the turntable are filled with medicine, the position of the conical funnel still needs to be adjusted manually to avoid the conical funnel affecting the pressing operation, and the convenience is relatively lacking.

When the turntable 3 needs to be repaired, at this time the turntable 3 is in a non-working state, which means the pressing operation is completed. The first adjustment component 7 first raises the feeding component 4, so that the splash-proof component 8 on the feeding pipe 42 is separated from the turntable 3, and then the second adjustment component 6 is used to drive the connecting platform 62 to rotate, so that the orientation of the feeding pipe 42 changes and is away from the turntable 3, thereby facilitating the maintenance personnel to repair the turntable 3 that is not blocked by the conical feeding mechanism.

[0027] The connecting platform 62 includes a horizontal plate and a vertical plate, the vertical plate is vertically fixed on one side of the horizontal plate, and the horizontal plate is connected with the second adjustment component 6; the position of the vertical plate corresponds to the position of the feeding pipe 42, a through hole 621 is opened in the vertical plate, the feeding pipe 42 passes through the through hole 621, and the height and width of the through hole 621 are both greater than the height and width of the feeding pipe 42, so that the feeding pipe 42 has a certain moving space in the through hole 621.

[0028] The first adjustment assembly includes a first motor 61, a lead screw 71 connected to the output end of the first motor 61, a moving nut threadedly sleeved on the lead screw 71, and a telescopic rod 72 fixedly connected to the moving nut.

When the first motor 61 operates, the lead screw 71 rotates to drive the moving nut to move, thereby driving the telescopic rod 72 to expand and contract, so that the height of the storage bin 41 changes, and the feeding pipe 42 can move up and down in cooperation in the through hole 621.

[0029] The second adjustment assembly 6 includes a second motor and a rotating shaft connected to the output end of the second motor. The second motor is arranged on the base 2, and the rotating shaft is connected to the cross plate. When the second motor operates, the rotating shaft drives the connecting plate to rotate, thereby adjusting the position of the feeding pipe 42.

[0030] The splash-proof assembly 8 includes a splash-proof cover 81. A feeding groove 82 is formed in the splash-proof cover 81. The groove wall of the feeding groove 82 is arc-shaped, and the cross-sectional area of the feeding groove 82 is smaller than the cross-sectional area of the pressing groove 31, so that the pressed raw materials can fall into the pressing groove 31 more concentratedly, avoiding falling outside the pressing groove 31. The top end of the splash-proof cover 81 is fixedly connected to one end of the feeding pipe 42. The feeding pipe 42 is communicated with the feeding groove 82. The bottom end of the splash-proof cover 81 is slidably connected to the turntable 3 through a sliding member. The sliding member includes a pulley 83 installed at the bottom end of the splash-proof cover 81. The pulley 83 slides in an annular chute 84. The chute 84 is formed on the turntable 3 and is concentric with the turntable 3. As Figure 4 shown, a plurality of pressing grooves 31 are arranged in an equally spaced circumferential distribution on the turntable 3. When the turntable 3 rotates with the splash-proof cover 81 through the pulley 83 and the chute 84, the splash-proof cover 81 does not move. When a pressing groove 31 in the splash-proof cover 81 is filled with pressed raw materials, the turntable 3 rotates to alternate the next adjacent empty pressing groove 31 with the pressing groove 31 filled with pressed raw materials. The splash-proof cover 81 can always cover the outside of an empty pressing groove 31 about to be filled with pressed raw materials in place. An elastic member is provided on the ground of the splash-proof cover 81. The elastic member includes rubber, which can play a sealing role and also avoid large friction when the turntable 3 rotates.

[0031] A knocking component 9 is further provided in the through hole 621. The knocking component 9 includes a knocking block 91 and a power component 92.

One end of the rack 922 facing the material conveying pipe 42 is fixedly connected to the knocking block 91. A vertical groove is formed in the rack 922 and is slidably connected to a slider. The slider is arranged on the side wall of the through hole 621. When the power motor operates to drive the gear 921 to rotate, the rack 922 can drive the knocking block 91 to move up and down reciprocally. When the knocking block 91 moves down and impacts the material conveying pipe 42, it can produce an oscillating effect on the pressed raw material in the material conveying pipe 42, accelerating the discharge of the pressed raw material from the material conveying pipe into the pressing groove. When the first adjusting component 7 drives the material storage box 41 and the material conveying pipe 42 to rise, the power component 92 first drives the knocking block 91 to rise to the highest position, so that the knocking block 91 will not obstruct the rising material conveying pipe 42.

[0032] The implementation principle of the present utility model is as follows: When the material conveying operation needs to be carried out, the end of the material conveying pipe 42 that is not communicated with the material storage box 41 corresponds to the turntable 3, and the splash guard 81 also covers the pressing groove 31. When the material conveying operation is completed or the turntable 3 needs to be repaired, the first adjusting component 7 first drives the material conveying pipe 42 to rise so that the splash guard 81 is separated from the turntable 3, and then the second adjusting component 6 rotates so that the material conveying pipe 42 moves away from the turntable 3 and does not block the turntable 3.
