Description

Technical Field

[0001] The utility model relates to a shearing and pressing device for a medicine packaging bag, belonging to the technical field of medicine production equipment. Background Art

[0002] During the processing of medical supplies, packaging bags often need to be hot-stamped and cut. After hot-stamping and sealing, they are cut. During the processing and production of traditional medical supply packaging bags, it is not convenient to perform integrated hot-stamping and cutting.

[0003] To this end, a Chinese patent document with publication number CN110802878A discloses a hot pressing and cutting integrated mechanism for medical packaging bags, including a frame, a hydraulic cylinder, an arm, a movable extrusion mechanism, a telescopic spring rod and a fixed extrusion mechanism, wherein a hydraulic cylinder is arranged above the frame, the output end of the hydraulic cylinder is connected to the arm, a movable extrusion mechanism is installed at one end of the arm away from the hydraulic cylinder, a telescopic spring rod is connected between the movable extrusion mechanism and the arm, and a fixed extrusion mechanism is arranged on one side of the movable extrusion mechanism. The hot pressing and cutting integrated mechanism for medical packaging bags can perform hot pressing and cutting integrated processing on medical packaging bags, shortening the assembly line of medical packaging processing, and the device can also perform integrated processing on prefabricated medical packaging bags with one end open.

[0004] However, the mechanism uses a hydraulic cylinder as a driving element for hot pressing and cutting, and needs to be equipped with components such as a solenoid valve and a hydraulic station, which will lead to a substantial increase in the manufacturing cost of the mechanism.

[0031] The upper shearing and pressing mechanism 5 includes an upper shearing and pressing assembly, which is connected to the support frame 1 through two mounting frames.

[0032] The mounting frame comprises a double-ear seat B51 and an L-shaped swing arm 52. The double-ear seat B51 is arranged on the support frame 1, and one end of the L-shaped swing arm 52 is rotatably connected to the double-ear seat B51 through a pin. When in use, the double-ear seat B51 is fixedly installed on the work surface 11.

[0033] A limit block 50 is installed on the support frame 1 near the double-ear seat B51. The limit block 50 limits the maximum angle of the L-shaped swing arm 52 to rotate upward relative to the work surface 11.

[0035] The working principle or use process of the shearing and pressing device for medicine packaging bags described in the utility model is as follows:

[0036] The motor hot plate A41 and the electric heating plate B58 are connected to the power supply. After their temperature rises, the packaging bag that needs to be sheared and pressed is placed on the base 40. Then the staff steps on the foot pedal 2 with their foot to make it rotate downward. The foot pedal 2 pulls the linkage cross bar 31 downward through the push-pull rod 30, and the tension spring is stretched. At the same time, the linkage cross bar 31 pulls the L-shaped swing arm 52 downward relative to the work table 11 through the connecting rod 33. The I-shaped slider 57 follows the L-shaped swing arm 52 to move downward and cooperate with the base 40 to clamp the packaging bag. The two motor hot plates A41 and the two electric heating plates B58 press the packaging bags one by one, and then the C-shaped groove block 54 continues to move downward relative to the I-shaped slider 57, the compression spring 55 is compressed, the upper shear knife 56 extends out of the staggered knife groove 570, and then extends into the feed groove 43 to cooperate with the lower shear knife 42 to achieve packaging bag shearing.

[0037] After the staff releases the foot pedal 2, the tension spring shortens and recovers its deformation. On the one hand, the push-pull rod 30 is driven by the linkage cross bar 31 to pull the foot pedal 2 upward and rotate. On the other hand, the connecting rod 33 is driven by the linkage cross bar 31 to push the L-shaped swing arm 52 to rotate upward relative to the work surface 11. The L-shaped swing arm 52 drives the upper shearing and pressing assembly to separate from the lower shearing and pressing mechanism 4, and the compression spring 55 stretches and recovers its deformation, pushing the I-shaped slider 57 to move downward relative to the C-shaped groove block 54, so that the upper shear knife 56 retreats to the staggered knife groove 570 again, thereby realizing the overall reset of the device.
