Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, and in particular relates to a vacuum blood collection tube sterilization and packaging machine. Background Technology

[0002] Vacuum blood collection tubes are disposable, negative pressure vacuum glass tubes that enable quantitative blood collection. They need to be used with a venous blood collection needle. Under negative pressure, they automatically and quantitatively collect venous blood samples. One end of the blood collection needle is inserted into the human vein, and the other end is inserted into the rubber stopper of the vacuum blood collection tube, allowing the blood to flow in automatically.

[0003] However, in existing packaging machines, the contact time between the sealing device and the packaging bag is relatively short during the sealing process. This short contact time means that the opening of the packaging bag does not have enough time to seal, resulting in uneven sealing of the opening, which reduces the pass rate of the packaging and affects the overall quality of the packaging. To address this, we propose a vacuum blood collection tube sterilization packaging machine. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum blood collection tube sterilization and packaging machine. By setting a sealing component, specifically, at a certain moment during the rotation of the eccentric shaft of the eccentric turntable from its highest point to its lowest point, the sealing plate contacts the packaging bag. As the eccentric turntable rotates, through a series of mechanical linkages, the round rod continues to move downwards, and the round rod begins to press down on the spring until the eccentric shaft of the eccentric turntable reaches its lowest point. The setting of the spring allows for a longer contact time between the sealing plate and the packaging bag, improving the sealing quality. This solves the problem in existing packaging machines where the contact time between the sealing device and the packaging bag is too short during the sealing process. The short contact time means that the opening of the packaging bag does not have enough time to seal, resulting in uneven sealing of the opening, reducing the qualified rate of the packaging, and thus affecting the overall quality of the packaging.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a vacuum blood collection tube sterilization and packaging machine, including a base and a motor. Two conveying rollers are provided on the top of the base. A film sleeve module is provided on the right side of the left conveying roller. The inner side of the film sleeve module is fixedly connected to the outer surface of the base.

[0007] A sealing assembly is provided above the base. The sealing assembly includes a housing. A second motor is fixedly connected to the left side of the housing. An eccentric turntable is fixedly connected to the output end of the second motor. A connecting rod is rotatably connected to the right side of the eccentric turntable. A movable frame is hinged to the bottom of the connecting rod. A slide rail is slidably connected to the back of the movable frame. The left side of the slide rail is fixedly connected to the left inner wall of the housing. A round rod is fixedly connected to the bottom of the movable frame. A round shell is slidably connected to the outer surface of the bottom of the round rod. A spring is fixedly connected to the inner side of the bottom of the round shell. The top of the spring contacts the bottom of the movable frame. A sealing plate is fixedly connected to the bottom of the spring.

[0008] Support arms are fixedly connected to both the front and back of the outer shell. Two hanging plates are fixedly connected to the top of the sealing plate. At a certain moment during the process of the eccentric shaft of the eccentric turntable rotating from the highest point to the lowest point, the sealing plate contacts the packaging bag. As the eccentric turntable rotates, through a series of mechanical linkages, the round rod continues to move downwards. The round rod begins to press down on the spring until the eccentric shaft of the eccentric turntable rotates to the lowest point. The setting of the spring makes the contact time between the sealing plate and the packaging bag longer, thus improving the sealing quality.

[0009] Furthermore, both of the conveyor rollers are rotatably connected to support frames on their front and back sides. A motor is fixedly connected to the front of the support frame located on the left side of the front side. The front of the conveyor roller located on the left side is fixedly connected to the output end of the back of the motor via a coupling. The motor provides power for the rotation of the conveyor roller, ensuring the stability and continuity of the conveyor belt transportation. The transportation efficiency of the conveyor belt is controlled by changing the rotation speed of the motor.

[0010] Furthermore, a base plate is fixedly connected to the center of the top of the base, and the top of the base plate is fixedly connected to the bottom of the support arm. The base plate serves to support the conveyor belt and prevent the conveyor belt from deforming and loosening after long-term cutting and sealing, thus affecting the transportation effect.

[0011] Furthermore, a fixed frame is fixedly connected to the top of the base plate, and three sliding rods are slidably connected inside the fixed frame. The sliding rods limit the movement of the moving rod and provide it with a stable movement path, preventing pressure from one side from causing friction and wear between the moving rod and the inner wall.

[0012] Furthermore, a second spring is provided on the outer surface of the slide rod. The bottom of the second spring is fixedly connected to the inner side of the bottom of the fixed frame. When the hanging plate moves upward, there is no pressure above the moving rod, and the second spring will spring the moving rod back to its original position to avoid affecting the transport of blood collection tubes by the conveyor belt.

[0013] Furthermore, a movable rod is slidably connected to the outer surface of the slide rod, and a cutting plate is fixedly connected to the bottom of the movable rod. The hanging plate on the sealing plate will drive the cutting plate to move downward, thereby performing a cutting operation on the packaging bag. The movement of the sealing plate drives the movement of the cutting plate, and the second spring makes the cutting plate fit more closely to the packaging bag, improving the cutting quality.

[0014] This utility model has the following beneficial effects:

[0015] This invention features a sealing assembly. Specifically, at a certain moment during the rotation of the eccentric shaft of the eccentric turntable from its highest to its lowest position, the sealing plate contacts the packaging bag. As the eccentric turntable rotates, through a series of mechanical linkages, the round rod continues to move downwards, pressing the spring downwards until the eccentric shaft of the eccentric turntable reaches its lowest position. The spring design allows for a longer contact time between the sealing plate and the packaging bag, thus improving the sealing quality.

[0016] This utility model features a cutting plate, specifically a hanging plate on the sealing plate that moves the cutting plate downwards to cut the packaging bag. As the eccentric turntable rotates from the bottom to the highest point, the hanging plate moves upwards. There is no pressure above the moving rod, and the spring returns the moving rod to its original position, thus avoiding any impact on the conveyor belt's transport of blood collection tubes.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-6 As shown, this utility model is a vacuum blood collection tube sterilization and packaging machine, including a base 1 and a motor 2. Two conveying rollers 21 are provided on the top of the base 1. A film sleeve module 4 is provided on the right side of the left conveying roller 21. The inner side of the film sleeve module 4 is fixedly connected to the outer surface of the base 1.

[0029] A sealing assembly 11 is provided above the base 1. The sealing assembly 11 includes a housing 111. A second motor 112 is fixedly connected to the left side of the housing 111. An eccentric turntable 114 is fixedly connected to the output end of the back of the second motor 112. A connecting rod 141 is rotatably connected to the right side of the eccentric turntable 114. A movable frame 151 is hinged to the bottom of the connecting rod 141. A slide rail 115 is slidably connected to the back of the movable frame 151. The left side of the slide rail 115 is fixedly connected to the left inner wall of the housing 111. A round rod 116 is fixedly connected to the bottom of the movable frame 151. A round shell 113 is slidably connected to the outer surface of the bottom of the round rod 116. A spring 161 is fixedly connected to the inner side of the bottom of the round shell 113. The top of spring 161 contacts the bottom of the movable frame 151, and a sealing plate 117 is fixedly connected to the bottom of spring 161. This utility model sets a sealing component 11, specifically, at a certain moment during the process of the eccentric shaft of the eccentric turntable 114 rotating from the highest point to the lowest point, the sealing plate 117 contacts the packaging bag. As the eccentric turntable 114 rotates, through a series of mechanical linkages, the round rod 116 continues to move downward, and the round rod 116 begins to press down on spring 161 until the eccentric shaft of the eccentric turntable 114 rotates to the lowest point. The setting of spring 161 makes the contact time between the sealing plate 117 and the packaging bag longer, thus improving the sealing quality.

[0030] Support arms 131 are fixedly connected to both the front and back of the outer casing 111, and two hanging plates 171 are fixedly connected to the top of the sealing plate 117.

[0031] Both conveyor rollers 21 are rotatably connected to support frames 3 on the front and back. The support frame 3 located on the left side of the front is fixedly connected to motor 2. The front of the conveyor roller 21 located on the left side is fixedly connected to the output end of the back of motor 2 via a coupling.

[0032] A base plate 5 is fixedly connected to the top center of the base 1, and the top of the base plate 5 is fixedly connected to the bottom of the support arm 131.

[0033] A fixed frame 51 is fixedly connected to the top of the base plate 5, and three sliding rods 52 are slidably connected inside the fixed frame 51.

[0034] A second spring 53 is provided on the outer surface of the slide bar 52, and the bottom of the second spring 53 is fixedly connected to the inner side of the bottom of the fixed frame 51.

[0035] A movable rod 55 is slidably connected to the outer surface of the slide rod 52, and a cutting plate 54 is fixedly connected to the bottom of the movable rod 55. This utility model uses the cutting plate 54, specifically the hanging plate 171 on the sealing plate 117, to drive the cutting plate 54 to move downward, thereby cutting the packaging bag. During the process of the eccentric turntable 114 rotating from the bottom to the highest point, the hanging plate 171 moves upward, and there is no pressure above the movable rod 55. The spring 53 bounces the movable rod 55 back to its original position, avoiding the impact of the conveyor belt on the transportation of blood collection tubes.

[0036] A specific application of this embodiment is as follows: First, the blood collection tubes are placed on the left side of the conveyor belt according to the predetermined process specifications. Then, motor 2 is started to drive the left conveyor roller 21 connected to it to start rotating. Since the conveyor rollers 21 are connected to each other through the conveyor belt, when the left conveyor roller 21 rotates, it will drive the right conveyor roller 21 to rotate synchronously through the transmission action of the conveyor belt, thereby achieving smooth transmission of the blood collection tubes on the conveyor belt. Next, the film-covering module 4 is started to cover the blood collection tubes on the conveyor belt with packaging bags. Motor 112 is started. With the start of motor 112, the eccentric turntable 114 starts to rotate. During the rotation of the eccentric turntable 114, it will drive the connecting rod 141 connected to it to perform vertical reciprocating motion along the preset path of the slide rail 115. The reciprocating motion of the connecting rod 141 will further drive the moving frame 151 connected to it to perform synchronous reciprocating motion. During the reciprocating motion of the moving frame 151, it will drive the round rod on it. 116 performs a corresponding reciprocating motion, and the round rod 116 drives the round shell 113 to perform a reciprocating motion. The bottom of the round shell 113 is provided with a sealing plate 117. Therefore, the reciprocating motion of the round shell 113 will drive the sealing plate 117 to perform a corresponding reciprocating motion. At a certain moment when the eccentric shaft of the eccentric turntable 114 rotates from the highest point to the lowest point, the sealing plate 117 will just come into contact with the packaging bag being conveyed. At this time, the hanging plate 171 on the sealing plate 117 will drive the cutting plate 54 to move downward, thereby cutting the packaging bag. As the eccentric turntable 114 continues to rotate, through a series of mechanical linkages to transmit force, the round rod 116 will continue to move downward. During this process, the round rod 116 will begin to compress the spring 161 downward until the eccentric shaft of the eccentric turntable 114 rotates to the lowest point. The setting of the spring 161 plays a key role here, so that the sealing plate 117 can maintain contact with the packaging bag for a longer time, thereby ensuring the improvement of sealing quality.
