Description

Technical Field

[0001] This utility model relates to the technical field of blood collection tube production equipment, specifically a large-capacity test tube storage and feeding machine. Background Technology

[0002] Blood collection tubes are specialized containers used in medical testing to collect blood samples. Currently, the hoppers in the tube-filling process of existing blood collection tube production technologies are too small, with a maximum capacity of only 800 tubes per batch. Manual loading is very frequent, occurring approximately every 20-40 minutes, averaging 30 minutes. This makes it impossible for workers to simultaneously attend to other tasks and provides care, resulting in relatively high labor intensity. Furthermore, the loading height of existing blood collection tube hoppers is typically around 1.5 meters, requiring workers to lift their arms high, further increasing the workload and placing certain demands on workers, making it difficult for ordinary female workers to perform. Therefore, this paper proposes a large-capacity test tube storage and feeding machine to solve the above problems. Utility Model Content

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide a large-capacity test tube storage and feeding machine to solve the problems mentioned in the background art, where the hoppers in the tube loading process of blood collection tube production are too small, and can only load a maximum of 800 test tubes at a time. The frequency of manual loading is very high, resulting in relatively high labor intensity and high requirements for workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-capacity test tube storage and feeding machine, comprising a base plate, an upper part of which has a large-capacity hopper and a storage chamber located inside the large-capacity hopper, an eccentric wheel rotatably disposed on one side of the bottom outlet of the storage chamber, an inclined swing plate disposed at the lower part of the storage chamber, the inclined end of the swing plate being hinged to the side wall of the storage chamber and the lower inclined end being mounted on the eccentric wheel, a scraper wheel rotatably disposed at the upper edge of the bottom outlet of the storage chamber, a test tube conveyor belt adjacent to the storage chamber inside the large-capacity hopper, the input end of the test tube conveyor belt corresponding to the bottom outlet of the storage chamber and adjacent to the scraper wheel, a guide plate fixed to the large-capacity hopper being disposed at the upper output end of the test tube conveyor belt, and a rotary drive assembly for driving the eccentric wheel and the scraper wheel to rotate synchronously, the rotary drive assembly being located outside the large-capacity hopper.

[0006] As a preferred embodiment of the large-capacity test tube storage and feeding machine of this utility model, the rotary drive assembly includes a first gear coaxially connected to the eccentric wheel, a second gear coaxially connected to the scraper wheel, a motor fixedly mounted on the base plate, and a main gear mounted on the output end of the motor and meshing with the first gear and the second gear respectively.

[0007] As a preferred embodiment of the large-capacity test tube storage and feeding machine of this utility model, the outer periphery of the scraper wheel is also provided with a rubber ring, and the upper part of the scraper wheel is also provided with a partition fixed to the inner side of the large-capacity hopper. One side of the partition is a storage chamber and the other side is a test tube conveyor belt.

[0008] In a preferred embodiment of the large-capacity test tube storage and feeding machine described in this utility model, the large-capacity hopper is tilted backward by 10°.

[0009] As a preferred embodiment of the large-capacity test tube storage and feeding machine described in this utility model, the main control unit, i.e., controller H of the test tube storage and feeding machine is also provided on the outside of the large-capacity hopper.

[0010] In a preferred embodiment of the large-capacity test tube storage and feeding machine described in this utility model, the height of the large-capacity hopper is less than or equal to one meter.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This large-capacity test tube storage and feeding machine, by placing test tubes into the storage chamber of a large-capacity hopper (the height of which is less than or equal to 1 meter), and then activating the test tube conveyor belt and the rotary drive assembly, allows the test tubes located at the bottom to enter the positioning slot under the action of gravity and oscillation. Meanwhile, the counter-rotating scraper wheel can remove test tubes that have not entered the positioning slot from the outlet, avoiding squeezing and tube jamming. Subsequently, the test tubes are lifted upwards by the test tube conveyor belt and sent out by the guide plate. In summary, this large-capacity test tube storage and feeding machine has the advantages of large single loading capacity and significantly reduced frequency of worker loading, allowing workers to take care of other work and maintenance, significantly reducing the labor intensity of workers, and is suitable for widespread application.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Secondly, this utility model is described in detail with reference to the schematic diagrams.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Figure 1-Figure 2 The diagram shown is a complete structural schematic of a large-capacity test tube storage and feeding machine according to this utility model. Please refer to [link / reference]. Figure 1-Figure 2 This embodiment of a large-capacity test tube storage and feeding machine includes a base plate 100, a large-capacity hopper 200 at the upper end of the base plate 100, and a storage chamber 210 located inside the large-capacity hopper 200. An eccentric wheel 400 is rotatably mounted on one side of the bottom outlet of the storage chamber 210. An inclined swing plate 300 is located at the lower part of the storage chamber 210. The upper inclined end of the swing plate 300 is hinged to the side wall of the storage chamber 210, and the lower inclined end is mounted on the eccentric wheel 400. A rotatable eccentric wheel is rotatably mounted on the upper edge of the bottom outlet of the storage chamber 210. The scraper wheel 800 and the large-capacity hopper 200 also have a test tube conveyor belt 500 adjacent to the storage chamber 210. The input end of the test tube conveyor belt 500 corresponds to the bottom outlet of the storage chamber 210 and is adjacent to the scraper wheel 800. The upper output end of the test tube conveyor belt 500 is also provided with a guide plate 700 fixed on the large-capacity hopper 200. It also includes a rotary drive assembly 600 for driving the eccentric wheel 400 and the scraper wheel 800 to rotate synchronously, and the rotary drive assembly 600 is located outside the large-capacity hopper 200.

[0019] The rotary drive assembly 600 includes a first gear 610 coaxially connected to the eccentric wheel 400, a second gear 620 coaxially connected to the scraper wheel 800, a motor 630 fixedly mounted on the base plate 100, and a main gear 640 mounted on the output end of the motor 630 and meshing with the first gear 610 and the second gear 620 respectively. It should be noted that the motor 630 and the electric drive for the test tube conveyor belt 500 are preferably variable frequency motors. This is to control the conveying speed and facilitate connection to different production equipment. In actual operation, the motor 630 drives the main gear 640 to rotate, which in turn drives the first gear 610 and the second gear 620 on both sides to rotate, thereby driving the eccentric wheel 400 and the scraper wheel 800 to rotate, thus achieving coordinated operation. Simultaneously, the rotation direction of the scraper wheel 800 should be opposite to the conveying direction of the test tube conveyor belt 500. The scraper wheel 800 also has a rubber ring on its outer periphery, and a partition 220 fixed to the inside of the large-capacity hopper 200 is located above the scraper wheel 800. One side of the partition 220 is a storage chamber 210 and the other side is a test tube conveyor belt 500. The rubber ring prevents the scraper wheel 800 from scratching the test tubes. Specifically, in this embodiment, test tubes are placed in the storage chamber 210 of a large-capacity hopper 200, where the height of the hopper 200 is less than or equal to 1 meter. Then, the test tube conveyor belt 500 and the rotary drive assembly 600 are activated. During this process, the test tubes located below enter the positioning groove 510 under the influence of gravity and oscillation. Meanwhile, the counter-rotating scraper wheel 800 removes test tubes that have not entered the positioning groove 510 from the outlet, preventing squeezing and jamming. The test tubes are then sequentially lifted upwards by the test tube conveyor belt 500 and sent out by the guide plate 700. In summary, this large-capacity test tube storage and feeding machine has the advantages of large single-load capacity and significantly reduced worker loading frequency, allowing workers to simultaneously manage other workstations and significantly reducing labor intensity, making it suitable for widespread application.

[0020] As a preferred option, the large-capacity hopper 200 is tilted backward by 10°. This tilting setting can prevent the test tubes from slipping during delivery, and the absence of a panel also facilitates loading and observation.

[0021] As a preferred option, the large-capacity hopper 200 is further equipped with the main control unit, i.e., controller H, of the test tube storage and feeding machine. In actual use, the operator can use controller H to control and set the various drive units and detection units of the feeding machine, making operation more convenient.

[0022] Preferably, the height of the large-capacity bucket 200 is less than or equal to one meter. Understandably, a lower height effectively reduces the operator's boom lifting range, making both equipment operation and material loading more convenient.

[0023] As a preferred option, a drive motor for rotating the test tube conveyor belt 500 is also provided on one side of the large-capacity hopper 200.

[0024] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
