Technical Field

The invention relates to a continuous automatic forced turnover device for a die strip, which is used for the automatic production of hollow hard capsules.

Background

The hollow hard capsule is more and more widely used in the field of medicine and food packaging. Due to the requirement of the production process, in the automatic production process of the hollow hard capsules, the die strip without the capsule needs to be turned over by necessary 90 degrees before dipping glue after being coated with oil.

The overturning device adopted by the existing automatic production line of the hollow hard capsules is a low-speed overturning device which freely overturns by depending on gravity, the overturning device is low in overturning speed and low in maximum overturning frequency limit, a mould strip is easy to topple over or separate from a track or even fall outside the production line (the mould strip is easy to damage) due to no limitation, the control is difficult, and a motor rotates in a high-frequency reciprocating mode (the motor is easy to damage), so that the production efficiency is low and the production cost is high.

Detailed Description

referring to fig. 1 to 7, the invention relates to a rapid continuous automatic turnover device for a mold strip, which is characterized by comprising a power device, a synchronous transmission mechanism and a mold strip turnover mechanism, wherein the mold strip turnover mechanism consists of two symmetrically arranged turnover rollers 10 which are rotatably arranged on a rack, and the power device arranged on the rack 11 respectively drives the two turnover rollers 10 to synchronously and reversely rotate through the synchronous transmission mechanism; four mold strip grooves 102 are uniformly distributed along the circumference of the turning roll 10, the mold strip grooves 102 penetrate through the axial direction of the turning roll, and a turning back plate 101 protruding out of the top of the mold strip groove 102 is arranged on the same side of each mold strip groove 102.

The power device comprises a motor 1 and a speed reducer 2, wherein an output shaft of the motor 1 is in transmission connection with an input end of the synchronous transmission mechanism through the speed reducer 2.

The synchronous transmission mechanism comprises a synchronous belt transmission mechanism and a gear set transmission mechanism, the synchronous belt transmission mechanism comprises a driving synchronous belt pulley 3, a synchronous belt 4 and a driven synchronous belt pulley 5, the driving synchronous belt pulley 3 is arranged on an output shaft of the power device and is in transmission connection with the driven synchronous belt pulley 5 through the synchronous belt 4, and the driven synchronous belt pulley is in coaxial connection with a driving gear 8; the gear set transmission mechanism comprises a first driven gear 6, an intermediate gear 7, a driving gear 8 and a second driven gear 9, wherein the first driven gear 6 and the second driven gear 9 are respectively arranged on end shafts of two turning rollers 10, and the driving gear 8 is meshed with the second driven gear 9 and is meshed with the first driven gear 6 through the intermediate gear 7. In order to ensure the synchronous rotation of the two turning rollers 10, the parameters of the first driven gear 6 and the second driven gear 9 are the same, and the parameters of the intermediate gear 7 and the driving gear 8 are the same.

When the automatic overturning device works, the motor 1 drives the driving synchronous belt wheel 3 to rotate through the speed reducer 2, the driven synchronous belt wheel 5 is driven to rotate through the synchronous belt 4, the driven synchronous belt wheel 5 and the driving gear 8 rotate coaxially, the driving gear 8 directly drives the second driven gear 9 to rotate in one direction, meanwhile, the middle gear 7 drives the first driven gear 6 to rotate in the opposite direction, and the first driven gear 6 and the second driven gear 9 respectively drive the two overturning rollers 10 to synchronously rotate in the opposite direction. Referring to fig. 7, after the mold strips filled with capsules are respectively arranged in the turning grooves 102 at the first and second positions of the two turning rollers 10 and turned by 90 degrees, the mold strips are respectively forced to turn to the third and fourth positions along the directions a and b, at this time, a system signal controls the motor 1 to stop rotating, the two turning rollers 10 are also stopped at the positions, and the mold strips are pushed out of the rotating range of the turning rollers 10 along the directions c and d by a subsequent mechanism; meanwhile, the subsequent die strip is pushed into the overturning groove 102 at the first and second positions again by the front end mechanism to repeat the overturning process, so that the die strip is continuously overturned by 90 degrees, and the aim of continuously and automatically overturning is fulfilled.
