Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicine granule filling, in particular to a packaging bag opening detection device. Background Art

[0002] The process of adjusting Chinese medicine granules includes bagging, clamping the bags, moving the clamped bags along the circumference of the adjusting equipment to different medicine bottles, filling different types of Chinese medicine granules into the bags, and sealing them. Therefore, the opening size of the bags needs to meet certain requirements, otherwise it will affect the adjustment of normal granules.

[0003] Chinese patent CN202122783508.1 discloses a Chinese medicine granule dispensing device, including a medicine bottle clamping mechanism, the medicine bottle clamping mechanism includes a first clamping plate and a dispensing head, the dispensing head is used to install the Chinese medicine granule bottle, the dispensing head moves in a circular motion along a closed loop line, the first clamping plate is connected to the dispensing head, the first clamping plate is provided with a first circulation component, the first circulation component is used to drive the dispensing head to move in a circular motion along the closed loop line; a medicine bag clamping mechanism, the medicine bag clamping mechanism is used to connect the Chinese medicine granule bag and transfer the Chinese medicine granule bag to the dispensing head for dispensing of the Chinese medicine granules; a base, the base is used to install the medicine bottle clamping mechanism and the medicine bag clamping mechanism and respectively match the Chinese medicine granule bottle with the Chinese medicine granule bag, so as to facilitate the filling of Chinese medicine granules into the Chinese medicine granule bag through the Chinese medicine granule bottle, which has the effect of automated Chinese medicine granule dispensing.

[0004] However, in this technical solution, after the granule bag is produced, it is clamped by the medicine bag clamping mechanism and transmitted backward.

[0013] As an improvement, the first bracket is slidably arranged in the guide groove, a first waist-shaped groove is provided on the first bracket, a slot hole is provided at the bottom of the guide groove, and the first bracket can be adjusted in the guide groove by a fastener.

[0014] As an improvement, the width of the first bracket matches the width of the guide slot, which is used to guide the first bracket during the reciprocating sliding process.

[0015] The beneficial effects of the utility model are:

[0016] (1) The utility model detects the opening contour of the packaging bag through the visual detection unit and compares it with the preset contour of the visual detection unit to ensure that the opening size of the packaging bag transmitted backwards 100% meets the size specified by the process, thereby preventing the leakage of Chinese medicine particles during the dispensing and filling process, resulting in insufficient Chinese medicine in the packaging bag and causing filling failure. At the same time, the medicine bags that failed to be filled cannot be detected, which affects the subsequent use of patients.

[0017] (2) The utility model realizes high-precision shooting by adjustably mounting the visual detection part on the first bracket and cooperating with the shielding member mounted at the bottom, thereby reducing the influence of the external light source and improving the shooting accuracy.
