Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, specifically a clamping device for processing pharmaceutical packaging boxes. Background Technology

[0002] In the pharmaceutical packaging manufacturing industry, pharmaceutical packaging boxes need to go through multiple processing steps such as die-cutting, folding, hot stamping, and printing. All of these require stable and reliable clamping and positioning of the paper packaging boxes. The performance of the clamping device directly affects the processing accuracy, production efficiency, and product yield. Existing clamping devices for pharmaceutical packaging box processing mainly include mechanical rigid clamping mechanisms and vacuum adsorption clamping mechanisms. Among them, mechanical rigid clamping mechanisms mostly use cylinders or motors to drive two clamping plates to clamp the packaging box. When the clamping force is too large or the contact surface is too hard, it is easy to leave indentations and scratches on the surface of the pharmaceutical packaging box. Secondly, although the vacuum adsorption clamping mechanism avoids contact damage, its applicability is quite limited. For packaging boxes with perforations, windows or vents on the surface, it cannot form an effective seal, resulting in insufficient adsorption force. Therefore, we propose a clamping device for pharmaceutical packaging box processing to solve the above problems. Utility Model Content

A bottom transmission mechanism 3 is fixedly installed on the top of the base 1, and a lifting cylinder 21 is fixedly installed on the top support 2. A top pressing mechanism 4 is fixedly installed on the driving end of the lifting cylinder 21. By opening the lifting cylinder 21, the top pressing mechanism 4 is driven to descend, thereby adjusting the distance between the bottom transmission mechanism 3 and the top pressing mechanism 4 to adapt to the processing, transmission and positioning of pharmaceutical packaging boxes of different thicknesses and sizes. Two symmetrically distributed side fixing mechanisms 5 are provided on the bottom transmission mechanism 3. The bottom transmission mechanism 3 includes two symmetrically distributed transmission side frames 31. A connecting crossbar 311 is fixedly installed at the end of each of the two transmission side frames 31. The two transmission side frames 31 are fixedly installed at the top of the base 1. A transmission roller 32 is rotatably installed at the end of each transmission side frame 31 near the connecting crossbar 311. A bottom transmission belt 33 is movably sleeved on the outside of the two transmission rollers 32. A plurality of support rollers 34 are rotatably installed between the two transmission side frames 31. The plurality of support rollers 34 are located in the bottom transmission belt 33. A first motor 35 is fixedly installed at one end of one of the transmission side frames 31. The drive end of the first motor 35 is fixedly installed with the shaft end of the corresponding transmission roller 32. By turning on the first motor 35, the corresponding transmission roller 32 is driven to rotate, thereby driving the bottom transmission belt 33 to perform transmission.

[0022] The pressing mechanism 4 includes two symmetrically distributed mechanism side frames 41. The mechanism side frames 41 are fixedly installed on the drive end of the lifting cylinder 21. Both ends of the mechanism side frames 41 are fixedly installed with connecting screws 42. Multiple pressing components 43 are evenly distributed on the two connecting screws 42.

[0023] The pressing component 43 includes a movable frame 431, which is slidably mounted on the connecting screw 42. The pressing component 43 can easily slide on the connecting screw 42, thereby flexibly adjusting the position of the pressing component 43 on the connecting screw 42. This allows for flexible adjustment of the pressing component 43's position on the medicine packaging box, facilitating the processing of different parts of the medicine packaging box and further enhancing the flexibility of the entire device. Two positioning nuts 421 are threadedly installed on the side of the connecting screw 42 near the pressing component 43. The movable frame 431 is located between the two positioning nuts 421 and is fixed by the positioning nuts 421. Both ends of the movable frame 431 are provided with transmission wheels 432. A top transmission belt 433 is movably sleeved on the outer side of the two transmission wheels 432. A support wheel 434 is provided in the middle of the movable frame 431 and is located in the top transmission belt 433. A connecting sleeve 435 is fixedly installed in the middle of the transmission wheels 432 and the support wheel 434. The connecting sleeve 435 is rotatably mounted on the movable frame 431. A drive shaft 44 corresponding to the position of the transmission wheels 432 and the support wheel 434 is rotatably mounted on the side frame 41 of the mechanism. A sliding shaft rod 441 is provided in the middle of the drive shaft 44. The connecting sleeve 435 is slidably installed on the outer side of the corresponding sliding shaft rod 441. A second motor 45 is fixedly installed at one end of one of the side frames 41 of the mechanism. The drive end of the second motor 45 and the shaft end of the corresponding drive shaft 44 are fixedly mounted. The installation is completed by activating the second motor 45 to drive the corresponding drive shaft 44 and the sliding shaft 441 to rotate, thereby driving the corresponding multiple connecting cylinders 435 and transmission wheels 432 to rotate, which in turn drives multiple top conveyor belts 433 to perform transmission. The transmission direction of the top conveyor belts 433 is opposite to that of the bottom conveyor belts 33. The medicine packaging box is placed between the bottom conveyor belts 33 and the top conveyor belts 433, with the upper surface of the medicine packaging box contacting the lower surface of the top conveyor belts 433 and the lower surface of the medicine packaging box contacting the upper surface of the bottom conveyor belts 33. This provides a transmission-type positioning clamping for the medicine packaging box. Compared with traditional mechanical rigid clamping and vacuum adsorption clamping, it can stably clamp different types of medicine packaging boxes and reduce scratches and pressure damage to the medicine packaging boxes.

[0024] The side positioning mechanism 5 includes multiple evenly distributed mounting brackets 51, which are fixedly mounted on the transmission side frame 31. Threaded crossbars 52 are movably inserted into the top of the mounting brackets 51. Positioning side plates 53 are fixedly mounted at the ends of the multiple threaded crossbars 52. Two limiting nuts 54 are threaded onto the outer side of the threaded crossbars 52. The mounting brackets 51 are located between the two limiting nuts 54. The distance between the two positioning side plates 53 is adjusted according to the width of the medicine packaging box, so that the side end of the medicine packaging box contacts the opposite side of the positioning side plate 53, thereby positioning the side end of the medicine packaging box.

[0025] Working principle: When in use, first adjust the distance between the two positioning side plates 53 according to the width of the medicine packaging box, so that the side of the medicine packaging box and the opposite side of the positioning side plate 53 come into contact, which facilitates the positioning of the side of the medicine packaging box. Subsequently, based on the thickness of the medicine packaging box, the lifting cylinder 21 is activated to drive the top pressing mechanism 4 to descend, thereby adjusting the distance between the bottom transmission mechanism 3 and the top pressing mechanism 4 to adapt to the processing, transmission and positioning of medicine packaging boxes of different thicknesses and sizes. Subsequently, the position of the pressing component 43 is adjusted according to the processing part of the medicine packaging box to prevent the pressing component 43 from pressing on the processing part of the medicine packaging box. The movable frame 431 is manually slidable and fixed with the positioning nut 421, so as to flexibly adjust the position of the pressing component 43 on the connecting screw 42, thereby flexibly adjusting the part of the pressing component 43 that presses and positions the medicine packaging box. By activating the first motor 35, the corresponding transmission roller 32 is driven to rotate, thereby driving the bottom transmission belt 33 to perform transmission. By activating the second motor 45, the corresponding drive shaft 44 and sliding shaft 441 are driven to rotate, thereby driving the corresponding multiple connecting cylinders 435 and transmission wheels 432 to rotate, which in turn drives multiple top conveyor belts 433 to perform transmission. The transmission direction of the top conveyor belts 433 is opposite to that of the bottom conveyor belts 33. The medicine packaging box is placed between the bottom conveyor belts 33 and the top conveyor belts 433, with the upper surface of the medicine packaging box contacting the lower surface of the top conveyor belts 433 and the lower surface of the medicine packaging box contacting the upper surface of the bottom conveyor belts 33, thereby performing transmission-type positioning and clamping of the medicine packaging box.
