Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to an impurity detection device for metoclopramide hydrochloride injection. Background Art

[0002] In the pharmaceutical industry, the production quality of metoclopramide hydrochloride injection is of vital importance, among which the detection of impurities is a key link in ensuring product quality. However, traditional impurity detection equipment often has problems such as low detection efficiency, insufficient automation and poor cleaning effect, which seriously restrict the improvement of production efficiency and product quality.

[0003] Traditional impurity detection equipment usually uses a straight conveyor belt to transport injection bottles. This design not only limits the conveying efficiency, but also makes it difficult to achieve stable control and precise positioning of the bottles during the detection process. In addition, traditional cleaning methods often rely on manual operation or simple mechanical scraping, which makes it difficult to ensure the cleaning effect and easily causes damage to the bottles. In the detection process, traditional equipment usually uses a fixed light source for irradiation, which makes it difficult to achieve all-round and multi-angle detection of impurities in the injection solution, thereby increasing the risk of missed detection and false detection.

That is, when a packaging bottle is clamped at the material control frame, the side wall of the toggle block is tangent to the interlocking frame, and the cleaning scraper is in contact with the packaging bottle.

[0014] The present invention provides a device for detecting impurities of metoclopramide hydrochloride injection, which has the following beneficial effects: The equipment uses a curved conveyor with a semicircular track design to ensure the one-way and stable conveying of injection bottles. This design not only improves the conveying efficiency, but also provides an ideal operating platform for the subsequent bottle control, cleaning and inspection steps. On the inner side of the middle of the curve, the bottle control assembly is driven by a double-headed motor to achieve precise control of the bottles. The material control rack is designed with a "cross" structure. Each rotation of 90 degrees can accurately control the passage of a bottle, and the free rotation of the auxiliary wheel ensures the smooth movement of the bottle body and reduces friction and damage.

[0015] Through the combination of the buffer rod and spring set vertically on the back, the cleaning component can closely contact the bottle body and effectively scrape off the dirt with the cleaning scraper. The dirt is then accurately guided to the collection box through the dust removal slot, which not only keeps the equipment clean, but also facilitates subsequent cleaning work. In particular, the tangent design of the cleaning scraper and the cleaning scraper cleverly realizes the self-cleaning of residual dirt on the cleaning scraper, further improving the cleaning efficiency and effect, and ensuring that the presence of impurities in the injection solution can be more accurately judged during testing.

[0016] In the detection process, the equipment makes full use of the light inspection technology of the light inspection machine and auxiliary spotlights, combined with the optimized setting of the solid color backboard, to conduct a comprehensive and detailed inspection of the rotating packaging bottles. The ingenious design of the lifting component enables the rotating plate and the contact plate to clamp the packaging bottles and drive them to rotate, thereby realizing the layer-by-layer inspection of the injection packaging bottles during the rising process. During this process, the pressure sensor embedded in the contact plate monitors the presence of the packaging bottles in real time, and triggers subsequent actions once it senses pressure, ensuring the continuity and accuracy of the inspection.

[0017] In addition, the equipment has cleverly designed the interaction mechanism between the interlocking sleeve and the interlocking frame to ensure the smoothness and safety of the entire process. The interaction between the ring groove of the toggle block and the interlocking frame allows the cleaning scraper to automatically move outward when the bottle is conveyed, avoiding interference with the bottle body, and automatically reset when the material control rack clamps the next bottle, maintaining a clean state. This design not only improves the automation level of the equipment, but also further ensures the continuity and accuracy of detection.

[0018] In summary, the impurity detection device for metoclopramide hydrochloride injection proposed in the present invention, with its unique design concept, precise mechanical structure and efficient detection technology, realizes efficient and accurate detection of impurities in injection packaging bottles. The device not only improves production efficiency and product quality, but also provides strong technical support for the automation and intelligent development of the pharmaceutical industry, showing significant technological progress and practical value.

[0030] Among them, two buffer rods 801 parallel to each other are vertically arranged on the back of the cleaning component 8, and the buffer rods 801 are vertically slidably inserted on the mounting plate body 702. The buffer rods 801 are provided with springs 802 that always provide the cleaning component 8 with a thrust toward the side of the curved conveyor 1. The end of the cleaning component 8 close to the curved conveyor 1 is provided with a cleaning scraper 803 for cleaning the bottle body of the packaging bottle to be inspected. The cleaning scraper blade 703 is tangent to the cleaning scraper blade 803. When the cleaning scraper blade 803 moves outward, the cleaning scraper blade 703 and the cleaning scraper blade 803 are tangent to each other. The contact is used to clean the dirt remaining on the cleaning scraper 803.

[0031] Among them, the detection sleeve 11 is an L-shaped structure, the upper end of the detection sleeve 11 is a closed end, the lower end of the detection sleeve 11 is an open end, the upper end of the support frame 9 extends to the inner cavity of the detection sleeve 11, and a light inspection machine 901 and an auxiliary spotlight 902 are provided. There are two auxiliary spotlights 902, which are distributed on both sides of the light inspection machine 901. The light inspection machine 901 and the auxiliary spotlights 902 jointly illuminate the side wall of the inner cavity of the detection sleeve 11 on the side where the cleaning component 8 is located.

[0032] Embodiment 2, on the basis of embodiment 1, a connecting shaft 1101 is vertically provided in the middle of the detection sleeve 11, and a connecting plate 1103 is vertically and horizontally clamped on the upper end of the connecting shaft 1101, and side guide rods 1104 are vertically upwardly provided on the left and right sides of the detection sleeve 11, and the upper ends of the side guide rods 1104 vertically slide through the connecting plate 1103, and a tension spring 1105 is connected between the bottom of the connecting plate 1103 and the end block at the lower end of the side guide rod 1104, and the tension spring 1105 provides a downward pulling force for the connecting shaft 1101 and the contact plate 1102 through the connecting plate 1103, and the lower end of the connecting shaft 1101 is a contact plate 1102 for cooperating with the rotating plate 501 to clamp the packaging bottle, and a pressure sensor is embedded in the bottom surface of the contact plate 1102. The sensor is a solid-color back plate 1106 provided on the side wall of the inner cavity of the detection sleeve 11 opposite to the light inspection machine 901. The solid-color back plate 1106 is used to cooperate with the light inspection machine 901 to perform light transmittance detection on the injection liquid in the packaging bottle. When the pressure sensor is squeezed, a signal is sent to the control box 10 for processing, and the piston rod of the lifting cylinder 3 is pushed upward, and the rotating motor 5 drives the rotating plate 501 to rotate. The packaging bottle between the rotating plate 501 and the contact plate 1102 rotates accordingly, and the light inspection machine 901 completely rotates the injection liquid in the packaging bottle from top to bottom for detection, so that the injection liquid packaging bottle can maintain a rotating state during the rising process for layer-by-layer detection, and can keep the bottle body clean, thereby reducing the probability of false alarms in detection and improving the accuracy of detection.

[0033] The working principle of this embodiment: When the equipment is started, the curved conveyor 1, with its semicircular track design, transports injection bottles in a unidirectional and stable manner. On the inner side of the middle of the curve, the bottle control assembly plays a key role. Driven by the double-headed motor 2, the toggle block 201 connected to the lower end shaft works in conjunction with the material control rack 202 and auxiliary wheel 203 installed on the upper end shaft. The material control rack 202 is designed with a "cross" structure. Each time it rotates ninety degrees under the drive of the double-headed motor 2, it accurately controls the passage of a packaging bottle. The auxiliary wheel 203 rotates freely on the upper end of the material control rack 202 to ensure the smooth movement of the bottle body and reduce friction.

[0034] As the packaging bottles move, they pass through the cleaning assembly 8. The assembly slides vertically on the mounting plate 702 through the buffer rod 801 vertically arranged on the back, and the spring 802 provides continuous thrust for the cleaning assembly 8 to keep it in close contact with the bottle body. The cleaning scraper 803 is responsible for scraping off the dirt on the bottle body, and the dirt is guided to the collection box 7 below through the dust removal groove 102 at the upper end of the curved conveyor 1. In particular, the cleaning blade 703 is designed to be tangent to the cleaning scraper 803. When the cleaning scraper 803 moves outward, the cleaning blade 703 can clean the dirt remaining on it, maintain the cleaning efficiency, and ensure that the presence of impurities in the injection liquid can be more accurately detected during the inspection.

[0035] When the bottle assembly is accurately transported to the detection area, the lifting assembly starts to work. The lifting cylinder 3 pushes the rotating motor 5 and the rotating plate 501 above to rise until the rotating plate 501 contacts the bottle. At this time, the contact plate 1102 below the detection sleeve 11 also maintains a slight clamping force on the bottle through the combined design of the connecting shaft 1101, the connecting plate 1103 and the tension spring 1105. Once the pressure sensor embedded in the contact plate 1102 senses the pressure, it sends a signal to the control box 10 to trigger subsequent actions.

[0036] Subsequently, the rotating motor 5 is started to rotate the packaging bottle between the rotating plate 501 and the contact plate 1102. The light inspection machine 901 and the auxiliary spotlight 902 in the detection sleeve 11 work together to perform light transmission inspection on the rotating packaging bottle. The setting of the solid color back plate 1106 optimizes the inspection environment and ensures that the light inspection machine 901 can accurately capture any impurities or abnormalities in the injection solution.

[0037] It is worth mentioning that the interlocking sleeve 6 and the interlocking frame 601 design between the bottle control assembly and the collection box 7 ensure the smoothness and safety of the entire process. The interaction between the annular groove 2011 of the toggle block 201 and the interlocking frame 601 enables the cleaning scraper 803 to automatically move outward when the packaging bottle is conveyed to avoid interference, and automatically return to its original position when the material control frame 202 clamps the next packaging bottle to maintain a clean state.
