Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, in particular to a sealing hot pressing device used for the production of biological reagents. Background Art

[0002] As we all know, the sealing and hot pressing device used in the production of biological reagents is usually a device specially used for sealing and hot pressing biological reagents. The main function of this device is to seal the container containing the biological reagents during the production process of the biological reagents to prevent leakage and contamination of the reagents and ensure the storage and use quality of the reagents.

[0003] Generally speaking, this sealing and hot pressing device may include the following parts:

[0004] (1) Heating element: used to generate heat to seal the container. (2) Pressure applying mechanism: applies pressure to the container to seal it. (3) Control system: used to control parameters such as heating temperature, pressure and time to ensure the quality of sealing. (4) Container positioning device: ensures that the container maintains a stable position during the sealing process. This device can be used in the production of various biological reagents, such as cell culture fluid, enzyme reagents, antibody reagents, etc. By using a sealing hot pressing device, the packaging sealing and stability of biological reagents can be improved, and the purity and activity of the reagents can be guaranteed.

[0005] However, the sealing parts of the existing sealing hot pressing devices often lack buffer protection functions, which easily leads to damage to the sealing parts or biological reagent containers. Therefore, there is a need in the art to add a buffer component to the sealing part to prevent direct impact on the container when excessive pressure is applied, so as to reduce the damage to the sealing part or the biological reagent container. To this end, we have designed a sealing hot pressing device for biological reagent production. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a sealing hot pressing device for the production of biological reagents.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A sealing hot pressing device for biological reagent production comprises a machine platform and an operating table fixedly mounted on the machine platform, a top plate fixedly mounted on the rear side of the operating table through a stand, a hydraulic cylinder fixedly mounted on the bottom of the top plate, a sealing hot pressing head is also arranged below the hydraulic cylinder, and a sealing machine heating strip with an annular structure is fixedly mounted on the bottom side of the sealing hot pressing head, and a placement groove for positioning the biological reagent container is also arranged on the top of the operating table; a buffer seat is fixedly connected to the output end of the hydraulic cylinder, a buffer column is fixedly connected to the top of the sealing hot pressing head, a buffer cavity is arranged on the buffer seat, and the top end of the buffer column movably penetrates into the buffer cavity and is fixedly connected to a movable disk, and a first spring is fixedly connected between the movable disk and the inner wall of the bottom side of the buffer cavity;

[0009] The two sides of the top of the movable disk are rotatably connected with rotating connecting rods, and the two rotating connecting rods are cross-arranged; the top ends of the two rotating connecting rods are rotatably connected with sliding seats, and the sliding seats are slidably installed on the top inner wall of the buffer cavity; an end seat is also fixedly installed on the top inner wall of the buffer cavity located outside the sliding seat, and a second spring is fixedly connected between the sliding seat and the end seat; a third spring is also fixedly connected between the two sliding seats.

[0010] Furthermore, a transverse guide rod is fixedly connected between the two end seats, and the second spring, the third spring and the two slide seats are all slidably sleeved on the transverse guide rod along the horizontal direction.

[0011] Furthermore, a transverse guide hole is provided on the slide seat, and the slide seat is slidably sleeved on the transverse guide rod along the horizontal direction through the transverse guide hole.

[0012] Furthermore, a sliding block is provided on the top side of the sliding seat, a sliding groove is also provided on the inner wall of the top side of the buffer cavity, and the sliding block is slidably installed in the sliding groove along the horizontal direction.

[0013] Furthermore, guide balls are rollingly installed on both sides of the movable plate, ball guide grooves are provided on both inner walls of the buffer cavity, and one side of the guide ball extends into the ball guide groove and is rollingly connected with the inner wall of the ball guide groove along the vertical direction.

[0014] Furthermore, a sliding sleeve is fixedly sleeved on the inner wall of the bottom of the buffer cavity, and the buffer column slides in the vertical direction and penetrates the sliding sleeve.

[0015] By adopting the above structure, the utility model has the following beneficial effects:

[0016] The utility model has good buffering performance during the hot-pressing process of sealing the biological reagent container. When the heat-sealing pressure of the hot-pressing sealing head and the heating strip of the sealing machine is too large, the hot-pressing sealing head and the heating strip of the sealing machine can move upward as a whole for buffering. When the hot-pressing sealing head moves upward, the buffer column drives the movable disk to move upward and stretch the first spring. In this way, a part of the excessive heat pressure can be consumed through the deformation of the first spring.

[0017] At the same time, when the movable plate moves upward, the two sliding seats are driven to move away from each other through the two rotating connecting rods and squeeze the second spring. When the two sliding seats move away from each other, the third spring is stretched. In this way, the deformation of the second spring and the third spring can further play a role in buffering and dissipating energy.

[0018] In summary, the sealing and hot pressing device for the production of biological reagents can ensure that the sealing and hot pressing head and the heating strip of the sealing machine have good buffering performance during the sealing and hot pressing process through the mutual cooperation of multiple buffer components, thereby avoiding the existing sealing and hot pressing devices that lack buffering protection functions, which easily leads to damage to the sealing part or the biological reagent container. In this way, by adding a buffer component to the sealing part to prevent direct impact on the container when excessive pressure is applied, the damage to the sealing part or the biological reagent container is reduced, ensuring that the entire use process is safer and more reliable.

[0025] The two sides of the top of the movable disk 501 are rotatably connected with rotating connecting rods 503, and the two rotating connecting rods 503 are cross-arranged; the top ends of the two rotating connecting rods 503 are rotatably connected with sliding seats 504, and the sliding seats 504 are slidably installed on the top inner wall of the buffer cavity 500; an end seat 509 is also fixedly installed on the top inner wall of the buffer cavity 500 located outside the sliding seat 504, and a second spring 505 is fixedly connected between the sliding seat 504 and the end seat 509; a third spring 506 is also fixedly connected between the two sliding seats 504.

[0026] In this embodiment, a transverse guide rod 507 is fixedly connected between the two end seats 509, and the second spring 505, the third spring 506 and the two slides 504 are all slidably sleeved on the transverse guide rod 507 in the horizontal direction; a transverse guide hole 508 is provided on the slide 504, and the slide 504 is slidably sleeved on the transverse guide rod 507 in the horizontal direction through the transverse guide hole 508.

[0027] In this embodiment, a slider 510 is provided on the top side of the slide seat 504, and a slide groove is also provided on the inner wall of the top side of the buffer cavity 500, and the slider 510 is slidably installed in the slide groove along the horizontal direction; guide balls 511 are rollingly installed on both sides of the movable disk 501, and ball guide grooves 512 are provided on the inner walls of both sides of the buffer cavity 500, and one side of the guide ball 511 extends into the ball guide groove 512 and is rollingly connected with the inner wall of the ball guide groove 512 along the vertical direction.
