Description

Technical Field

[0001] This utility model relates to the field of vaccine filling technology, and in particular to a vaccine semi-finished product transfer and clamping device that allows for rapid vial replacement. Background Technology

[0002] During vaccine production, raw materials are mixed to form a semi-finished solution, which is then filled into vaccine vials. The vials are then sealed, and the sealed vaccine is freeze-dried using lyophilization technology. When filling the vials, the vials are first positioned using a transfer device before being moved to the filling and sealing machines. Existing filling production lines for vaccine vial transfer, in order to achieve mass production, employ a rotating disc that can clamp the vials on its side. The disc rotates within a clamping ring, and the two work together to transfer the vials.

[0003] However, when the vaccine production line is in use, it is driven by a motor. After long-term use, the motor will have positioning errors, and the vaccine bottles will often not move accurately under the filling machine and the sealing machine. There are gaps between the vaccine bottles and the rotating disk and the clamping ring, which causes the vaccine bottles to collide with the rotating disk and the clamping ring during the transfer process, causing the filled vaccine to spill out. In severe cases, it can even cause the vaccine bottles to break. Utility Model Content

[0004] The purpose of this invention is to provide a vaccine semi-finished product transfer and clamping device that allows for rapid vial replacement. By using a magnetic plate and a squeezing ball to pull each other, the rotation of the transfer tray is precisely positioned. The limiting plate can limit the position of the vaccine vial, preventing the vial from touching the inner wall of the clamping ring during transfer, thereby solving the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a vaccine semi-finished product transfer and clamping device that can quickly change bottles, including a clamping ring, a transfer disk rotatably connected to the middle of the clamping ring, a drive shaft fixedly connected to the middle of the transfer disk, a clamping groove for clamping the vaccine bottle on the side wall of the transfer disk, a sliding groove on the inner side wall of the clamping groove, and a limiting plate for limiting the position of the vaccine bottle slidably connected in the sliding groove to avoid the vaccine bottle from contacting the inner side wall of the clamping ring during the transfer process;

[0006] A positioning box is fixedly connected to the middle of the clamping ring, a connecting piece is slidably connected to the middle of the positioning box, and a compression ball is fixedly connected to the top of the connecting piece to control the extension or retraction of the limiting plate into the sliding groove.

[0007] The side end of the transfer tray is provided with a connecting groove, and a magnetic plate is fixedly connected to the inner side wall of the connecting groove. This magnetic plate is used to pull the extrusion ball and the connecting ball to move, magnetically position the extrusion ball, and position the transfer groove. An extrusion column is connected through the middle of the magnetic plate.

[0008] Preferably, the magnet plate has an arc-shaped structure, the top end of the extrusion column is located in the sliding groove, and the extrusion column extrudes the limiting plate when it is extruded and moved.

[0009] Preferably, the extrusion ball is an iron ball, the connector is a cross-shaped structure, and a return spring is fixedly connected between the side end of the connector and the inner wall of the positioning box for pulling the extrusion ball and the connecting column back to their original positions.

[0010] Preferably, the limiting plate has an extrusion groove on the side facing the magnet plate, and the inner wall of the extrusion groove has an inclined structure to guide the extrusion of the extrusion column and drive the limiting plate to move.

[0011] Preferably, the inner wall of the sliding groove is fixedly connected with a deformable piece with an arc-shaped structure. The side end of the deformable piece abuts against the top of the limiting plate. When the limiting plate moves, it squeezes and deforms the deformable piece, so that the deformable piece stores force.

[0012] Preferably, a slide is fixedly connected to the side end of the clamping ring, and an inclined ramp is provided in the middle of the slide to guide the vaccine bottle. A support plate is fixedly connected to the lower end of the clamping ring, and a discharge port is provided on the side end of the support plate to discharge the vaccine bottle that has been filled with vaccine and sealed.

[0013] Preferably, a pressing plate is fixedly connected to the top of the connector, and a control button is fixedly connected to the outer wall of the positioning box. The control button is connected to a motor that drives the drive shaft to rotate.

[0014] The beneficial effects of this utility model are as follows: When the transfer tray rotates within the clamping ring, when the connecting groove moves to the positioning box, the magnetic plate magnetically attracts the extrusion ball, and the extrusion ball extrudes the control button through the extrusion plate, thereby stopping the transfer tray from working and aligning the clamping groove with the slide rail, thus accurately positioning the rotation of the transfer tray. This facilitates the accurate movement of the vaccine vials to the filling and packaging equipment, avoiding positioning failures. After the vaccine vials move into the clamping groove, the limiting plate pops out of the sliding groove, which limits the vaccine vials, keeping them away from the inner wall of the clamping ring, preventing the vaccine vials from colliding and spilling when the transfer tray rotates.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] See Figures 1-4 This invention provides a vaccine semi-finished product transfer and clamping device for rapid vial replacement, comprising a clamping ring 1, a transfer disk 2 rotatably connected to the center of the clamping ring 1, and a drive shaft 9 fixedly connected to the center of the transfer disk 2. The fixed connection method can also be welding, riveting, screwing, or gluing. The side wall of the transfer disk 2 is provided with a clamping groove 3 for clamping the vaccine vials. A slide 4 is fixedly connected to the side end of the clamping ring 1, and an inclined slope is provided in the center of the slide 4 for guiding the vaccine vials. A support disk 8 is fixedly connected to the lower end of the clamping ring 1, and a discharge port 10 is provided on the side end of the support disk 8 for discharging the vaccine vials that have been filled with vaccine and sealed. When the transfer disk 2 is driven to rotate by the drive shaft 9, when the clamping groove 3 moves to the slide 4, the vaccine vials in the slide 4 will automatically slide down the inclined slope to the clamping groove 3. Due to the restriction of the clamping groove 3, only one vaccine vial can move into the transfer disk 2 at a time.

[0022] A sliding groove 6 is provided on the inner wall of the clamping groove 3. A limiting plate 17 for limiting the position of the vaccine bottle is slidably connected in the sliding groove 6 to prevent the vaccine bottle from contacting the inner wall of the clamping ring 1 during transportation.

[0023] A positioning box 5 is fixedly connected to the middle of the clamping ring 1. A connector 12 is slidably connected to the middle of the positioning box 5. A compression ball 11 is fixedly connected to the top of the connector 12 to control the extension or retraction of the limiting plate 17 into the sliding groove 6. The compression ball 11 is an iron ball. The connector 12 has a cross-shaped structure. A return spring is fixedly connected between the side end of the connector 12 and the inner wall of the positioning box 5 to pull the compression ball 11 and the connecting column back to their original positions. When the connecting groove 7 on the side end of the transfer tray 2 moves to the positioning box 5, the compression ball 11 is pulled into the connecting groove 7. The compression ball 11 drives the connector 12 to move and stretches the return spring to store force.

[0024] A pressing plate 13 is fixedly connected to the top of the connector 12, and a control button 14 is fixedly connected to the outer wall of the positioning box 5. The control button 14 is connected to the motor that drives the drive shaft 9 to rotate. When the connector 12 moves, it can drive the pressing plate 13 to move together and press the control button 14. The motor is equipped with a control microcontroller. The control button 14 is connected to the microcontroller. When the control button 14 is pressed, it is powered on. The microcontroller makes the motor stop working for a period of time, thereby accurately positioning the position of the transfer tray 2. This allows the vaccine bottles to be accurately moved to the filling and packaging equipment, avoiding positioning failure and enabling the vaccine bottles to be smoothly moved into the clamping groove 3.

[0025] The transfer tray 2 has a connecting groove 7 on its side. A magnetic plate 15 is fixedly connected to the inner wall of the connecting groove 7. This magnetic plate 15 is used to pull the extrusion ball 11 and the connecting ball to move, magnetically positioning the extrusion ball 11 and positioning the transfer groove. An extrusion column 16 is connected through the middle of the magnetic plate 15. The magnetic plate 15 has an arc-shaped structure. The top of the extrusion column 16 is located in the sliding groove 6. When the extrusion column 16 is extruded and moved, it extrudes the limiting plate 17. The magnetic plate 15 attracts the extrusion ball 11, so that the extrusion ball 11 can be inserted into the connecting groove 7 and extrude the extrusion column 16.

[0026] The limiting plate 17 has an extrusion groove 18 on its side facing the magnet plate 15. The inner wall of the extrusion groove 18 is inclined to guide the extrusion of the extrusion column 16 and drive the limiting plate 17 to move. The inner wall of the sliding groove 6 is fixedly connected to an arc-shaped deformable piece 19. The deformable piece 19 is formed by stamping elastic iron sheet. The curvature of the deformable piece 19 is precisely controlled to avoid the limiting plate 17 clamping the vaccine bottle with excessive force, which would prevent the vaccine bottle from falling out of the discharge port 10. The side of the deformable piece 19 abuts against the top of the limiting plate 17. When the limiting plate 17 moves, it extrudes and deforms the deformable piece 19, allowing the deformable piece 19 to store force. When the extrusion column 16 moves, it extrudes the inner wall of the extrusion groove 18, thereby pushing the limiting plate 17 to move and retract into the sliding groove 6. The vaccine bottle can then move smoothly into the clamping groove 3. As the transfer plate 2 continues to rotate, the extrusion ball 11 moves out of the connecting groove 7, the extrusion column 16 loses its extrusion, and the limiting plate 17 pops out under the action of the deformable piece 19, thereby limiting the position of the vaccine bottle and preventing the vaccine bottle from colliding with the inner wall of the clamping ring 1 when the transfer plate 2 rotates, thus preventing vibration when the transfer plate 2 transfers the vaccine bottle.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
