Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a pushing mechanism for a blood plasma bag breaking machine. Background Art

[0002] Plasma bag breakers are widely used in the medical industry to process and distribute plasma. In existing technologies, the pusher mechanism pushes the plasma bag directly to a designated location before returning it to its original position to push the next bag. This approach has numerous drawbacks in practical applications.

[0003] First, this push method results in a longer feeding time. Each push and return action requires a certain amount of time, which can reduce work efficiency in high-demand medical environments and affect the entire plasma processing process. Second, due to the long push stroke, the machine itself needs to be relatively larger to accommodate this push process. This not only increases the equipment's footprint but also potentially increases equipment manufacturing and maintenance costs.

[0004] In summary, there is an urgent need for a pushing mechanism for a plasma bag breaking machine that can reduce pushing formation, improve pushing efficiency, and save space. Utility Model Content

[0005] The purpose of the invention of the utility model is to provide a pushing mechanism for a blood plasma bag breaking machine to address the problems existing in the prior art, which can reduce the formation of pushed materials, improve the pushing efficiency and save space.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A pushing mechanism for a plasma bag breaker, comprising a conveying platform, on which a first plasma bag, a second plasma bag, and a third plasma bag are respectively arranged, the conveying platform comprising a conveyor belt and a pushing station, the pushing station being arranged on one side of the conveyor belt and forming an L-shaped structure with the conveyor belt;

[0008] A pushing mechanism is provided above the conveyor belt, and the pushing mechanism includes a driving device and a pushing plate. Driven by the driving device, the pushing plate synchronously pushes the plasma bag three to the next station and pushes the plasma bag two to the pushing station.

[0009] A lifting mechanism is provided below the pushing mechanism, and the lifting mechanism is used to realize the lifting and lowering of the pushing mechanism;

[0010] After the pushing mechanism completes one pushing operation, the lifting mechanism lifts the pushing mechanism, and the pushing mechanism returns to above the conveyor belt, and the lifting mechanism descends. During the process of the lifting mechanism completing one lifting action, the conveyor belt conveys the plasma bag to below the pushing plate.

[0011] It also includes a control system, which controls the linkage and coordination of the conveyor belt, the pushing structure and the lifting mechanism.

[0012] Preferably, the driving device is a pushing cylinder, and the output end of the pushing cylinder is connected to the pushing plate.

[0013] Preferably, the pusher plate includes two vertical plates and one horizontal plate, and the two vertical plates are arranged at both ends of the horizontal plate to form an approximately inverted "U"-shaped structure.

[0014] Preferably, the width of the approximately inverted "U"-shaped structure is greater than the width of the conveyor belt.

[0015] Preferably, the pushing plate is close to one end of the pushing station and is provided with two nearly "U"-shaped structures, which are respectively located at both ends of the vertical plate and are used to contact and horizontally push the plasma bag three.

[0016] Preferably, when the lifting mechanism is not working, the bottom of the push plate just contacts the conveying platform, and when the lifting mechanism lifts the push plate, it is lifted until the push plate leaves the conveying platform at a height greater than the height of the plasma bag.

[0017] Preferably, the lifting mechanism is a lifting cylinder, the output end of the lifting cylinder is connected to the pushing cylinder, and is arranged vertically to the pushing cylinder.

[0018] Preferably, the control system is a PLC controller.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] The present application is a pushing mechanism for a plasma bag breaking machine. The plasma bag contains frozen plasma and is in a fixed state. The present application is provided with a pushing mechanism, a lifting mechanism and a conveying platform. A plasma bag is provided under the pushing plate. Since the pushing plate of the present application is provided with a structure approximately inverted "U" shape, the plasma bag 2 is under the approximately inverted "U" shaped structure. When in use, the pushing cylinder works and extends, and the pushing plate pushes the plasma bag 3 located on the pushing station to the next station. At the same time, due to the structural setting of the pushing plate of the present application, the plasma bag 2 located on the conveyor belt is synchronously pushed to the pushing station, and then the lifting cylinder extends. The pushing cylinder and the pushing plate are lifted up, and the lifting height exceeds the height of the plasma bag. The pushing cylinder retracts, and the pushing plate also retracts until it is above the conveyor belt. The lifting cylinder descends, and the bottom of the pushing plate falls to the upper end of the conveying platform. At the same time, during the time period when the lifting cylinder completes a lifting action, the conveying bag conveys the plasma bag to the bottom of the pushing plate, and the above actions are repeated in sequence to complete continuous pushing. During the whole process, after the pushing mechanism pushes the plasma bag away, the conveying bag will push the next plasma bag to the designated position and directly carry out the next pushing. There is no need to wait, and the pushing stroke is reduced, which saves space in the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] A pushing mechanism for a plasma bag breaker, comprising a conveying platform 1, on which are respectively provided a plasma bag 1 2, a plasma bag 2 3 and a plasma bag 3 4, the conveying platform 1 comprising a conveyor belt 11 and a pushing station 12, the pushing station 12 being arranged on one side of the conveyor belt 11 and forming an L-shaped structure with the conveyor belt 11; a pushing mechanism is provided above the conveyor belt 11, the pushing mechanism comprising a driving device 51 and a pushing plate 52, the pushing plate 52 being driven by the driving device 51 to synchronously push the plasma bag 3 4 to the next station, and to push the plasma bag 2 3 Push to the pushing station 12; a lifting mechanism 6 is provided below the pushing mechanism, and the lifting mechanism 6 is used to realize the lifting and lowering of the pushing mechanism; after the pushing mechanism completes one pushing, the lifting mechanism 6 lifts the pushing mechanism, and the pushing mechanism returns to the top of the conveyor belt 11, and the lifting mechanism 6 descends. During the process of the lifting mechanism 6 completing one lifting action, the conveyor belt 11 conveys the plasma bag 2 to the bottom of the pushing plate 52; it also includes a control system, which controls the linkage and coordination of the conveyor belt 11, the pushing structure and the lifting mechanism 6. The pushing station 12 is flush with the upper surface of the conveyor belt 11, and the width of the pushing station 12 is greater than the maximum length of the plasma bag. The conveyor belt 11 can be driven by pneumatic drive or by an electric motor, etc. The specific driving method is an existing conventional technology, so it will not be described here.

[0027] Specifically, the driving device 51 is a push cylinder, and the output end of the push cylinder is connected to the push plate 52. The push cylinder is arranged perpendicular to the conveyor belt 11 and is used to push the push plate 52 to further push the plasma bag.

[0028] Specifically, the pusher plate 52 comprises two vertical plates and a horizontal plate, with the two vertical plates positioned at either end of the horizontal plate, forming a roughly inverted U-shaped structure. This inverted U-shaped structure allows the two vertical plates to push two plasma bags simultaneously, pushing plasma bag three to the next station and plasma bag two to the pusher station 11.

[0029] Specifically, the width of the approximately inverted "U"-shaped structure is greater than the width of the conveyor belt. That is, the two vertical plates of the push plate 52 can accommodate a plasma bag, so that the push plate 52 can push two plasma bags at the same time.

[0030] Furthermore, the push plate 52 is provided with two nearly "U"-shaped structures at one end near the push station 12, located at each end of the vertical plate, for contacting and horizontally pushing the plasma bag 4. The two nearly "U"-shaped structures are provided at the lower end of one side of the push plate 52. When in use, the plasma bag 4 can be pushed to the next station without changing its direction for subsequent operations, and it plays a balancing role during pushing.

[0031] Specifically, when the lifting mechanism 6 is not in operation, the bottom of the push plate 52 just contacts the conveying platform 1. When the lifting mechanism 6 lifts the push plate 52, it is lifted until the push plate 52 is above the conveying platform 1 at a height greater than the height of the plasma bag. When in use, the push plate 52 can smoothly push the plasma bag and does not touch the plasma bag when returning to its original position.

[0032] Specifically, the lifting mechanism 6 is a lifting cylinder, the output end of which is connected to the push cylinder and is arranged perpendicular to the push cylinder. The lifting mechanism 6 controls the lifting and lowering of the push cylinder, that is, controls the lifting and lowering of the push plate 52. When in use, the movement of the push cylinder can realize the return of the push plate and the cycle in sequence.

[0033] Specifically, the control system is a PLC controller. When in use, programming is first performed in the PLC controller, that is, the linkage and coordination of the push cylinder, the lifting cylinder, the conveyor belt, etc. is coordinated. The use of the PLC controller to control the linkage of the system is an existing conventional technology and will not be described in detail here.

[0034] Specifically, a base 7 is further provided below the lifting mechanism. The base 7 can be used to adjust the height of the lifting cylinder and thus adjust the height of the pushing mechanism.

[0035] When the present application is in use, the pushing cylinder 51 extends, and the pushing plate 52 pushes the plasma bag 3 4 located on the pushing station 11 to the next station, such as the plasma bag breaking mechanism. At the same time, the pushing plate 52 is arranged in an approximately inverted "U" shape. The plasma bag 2 located on the conveyor belt is synchronously pushed to the pushing station 11 under the action of the pushing plate 52, and then the lifting cylinder 6 extends to lift the pushing cylinder 51 and the pushing plate 52. The lifting height exceeds the height of the plasma bag, and the pushing cylinder 51 retracts, and the pushing plate 52 also retracts until it is above the conveyor belt 12. The lifting cylinder 6 descends, and the bottom of the pushing plate 52 falls to the upper end of the conveying platform 2. At the same time, during the time period when the lifting cylinder 6 completes a lifting action, the conveyor belt 12 conveys the plasma bag 2 to the bottom of the pushing plate 52, and the above actions are repeated in sequence to complete continuous pushing. During the whole process, due to the structural setting of the pushing plate, and the linkage cooperation of the lifting cylinder, the pushing cylinder and the conveyor belt, after the pushing mechanism pushes the plasma bag away, the conveyor bag will push the next plasma bag to the designated position, and directly carry out the next pushing without waiting, which reduces the pushing stroke and saves space in the machine.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
