Description

Technical Field

[0001] This utility model belongs to the field of freeze dryer technology, specifically relating to a discharge push rod structure for a freeze dryer. Background Technology

[0002] A freeze dryer, also known as a freeze dryer, is a cold-drying device that first freezes water-containing substances into a solid state, and then sublimates the water in the solid state into a gaseous state to remove moisture and preserve the substance. Existing freeze dryers require push rods to push items out after freezing, due to the low internal temperature. However, the fixed position of these push rods makes it difficult to adjust them according to the height of the freeze-dried items, limiting their applicability.

[0003] Therefore, a new discharge pusher structure for freeze dryers is needed to solve the problems of existing pushers having fixed positions, being inconvenient to adjust according to the height of the freeze-dried items, and having a limited range of applications. Utility Model Content

To better understand this invention, a detailed description is provided below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: Basic structure of the push rod structure;

[0024] like Figures 1 to 3As shown, this utility model provides a discharge pusher structure for a freeze dryer. It includes a freeze dryer body 1, with openings on both sides. A sliding door 2 is slidably installed on the freeze dryer body 1 at each opening. Four fixing blocks 3 are fixedly installed on one side of the freeze dryer body 1, and a threaded rod 4 is rotatably installed between two fixing blocks 3. A sliding block 5 is provided on one side of the freeze dryer body 1, with both sides of the sliding block 5 threadedly connected to two threaded rods 4. A cylinder 6 is fixedly installed on one side of the sliding block 5, and a push plate 7 is provided at the telescopic end of the cylinder 6. A worm gear 8 is fixedly installed at the top of the threaded rod 4, and a fixing plate 9 is fixedly installed at the top of the fixing blocks 3. A worm gear 10 is rotatably installed between two fixing plates 9. The worm gear 10 meshes with the worm wheel 8. A motor 11 is fixedly installed on one side of the fixed plate 9. The output end of the motor 11 is fixedly connected to the worm gear 10. After the freeze dryer finishes processing the goods, the freeze dryer belongs to the prior art. The specific structure and principle have been disclosed and will not be described in detail here. The freeze dryer is equipped with a power supply. By sliding the sliding doors 2 on both sides, the motor 11 is started, which drives the rod to rotate. The worm gear 10 drives the two worm wheels 8 to rotate, causing the two threaded rods 4 to rotate, which drives the sliding block 5 to move. According to the position of the goods in the freeze dryer, the position of the push plate 7 is adjusted. Then the cylinder 6 is started, which drives the push plate 7 to move, pushing the goods out of the freeze dryer.

[0025] Example 2: Design of the locking mechanism;

[0026] A mounting block 13 is fixedly installed on the telescopic end of the cylinder 6. A mounting groove 12 is opened on one side of the push plate 7. The mounting block 13 is movably inserted into the mounting groove 12. A locking mechanism is provided on both sides of the push plate 7 located in the mounting groove 12. The locking mechanism includes a groove 14, a spring 15, a moving block 16, and a limiting block 17. The groove 14 is opened on both sides of the mounting groove 12. One end of the spring 15 is fixedly installed on the side wall of the groove 14. One side of the moving block 16 is fixedly connected to the other end of the spring 15. The limiting block 17 is fixedly installed on one side of the moving block 16. Limiting grooves are opened on both sides of the mounting block 13. The limiting block 17 is movably inserted into the limiting groove. When the push plate 7 needs to be replaced, the moving block 16 is pushed to move, the spring 15 retracts, the limiting block 17 moves, and after the limiting block 17 disengages from the limiting groove, the push plate 7 can be removed, which facilitates the disassembly and cleaning of the push plate 7 and improves the disassembly and assembly efficiency.

[0027] Example 3: Structure and function of bellows 18;

[0028] A bellows 18 is fitted on the outer side of the telescopic end of cylinder 6. Both ends of the bellows 18 are fixedly installed with mounting rings 19. The side end of the mounting ring 19 is threaded with a fixing bolt 20. The mounting ring 19 is fixed to the push plate 7 or the sliding block 5 by the fixing bolt 20. The bellows 18 protects the telescopic end of cylinder 6. The fixing bolt 20 and the mounting ring 19 make it easy to disassemble and replace the bellows 18.

[0029] Example 4: Design and function of support rod 21;

[0030] A support rod 21 is fixedly installed at the bottom of the fixed block 3. The support rod 21 is fixedly connected to the freeze dryer body 1. The support rod 21 enhances the support strength of the entire push rod structure.

[0031] Example 5: Working principle of the push rod structure;

[0032] After the freeze dryer finishes processing the goods, the sliding doors 2 on both sides are slid open, the motor 11 is started, the rod is rotated, the worm gear 10 drives the two worm wheels 8 to rotate, the two threaded rods 4 rotate, and the sliding block 5 moves. The position of the push plate 7 is adjusted according to the position of the goods in the freeze dryer, and then the cylinder 6 is started to drive the push plate 7 to move and push the goods out of the freeze dryer.

[0033] When the push plate 7 needs to be replaced, the user can move the moving block 16, the spring 15 will retract, the limiting block 17 will move, and after the limiting block 17 disengages from the limiting groove, the push plate 7 can be removed, which facilitates the disassembly and cleaning of the push plate 7 and improves the efficiency of disassembly and assembly.

[0034] Technical effects:

[0035] Through the detailed description of the above embodiments, firstly, the arrangement of structures such as the fixed block 3, threaded rod 4, sliding block 5, cylinder 6, push plate 7, worm gear 8, fixed plate 9, worm 10 and motor 11 facilitates the adjustment of the push plate 7 position according to the height of the goods in the freeze dryer for material discharge, thereby improving discharge efficiency and enhancing practicality.

[0036] Secondly, the installation of the push plate 7 is facilitated by the structure of the mounting slot 12, mounting block 13, groove 14, spring 15, moving block 16 and limiting block 17, and the push plate 7 is easy to install and disassemble, and easy to replace and clean. The bellows 18 protects the extension and retraction end of the cylinder 6.

[0037] In summary, this utility model provides a freeze dryer discharge pusher structure with reasonable structure, complete functions, and strong applicability. It can adjust the discharge according to the height of the goods, enhances practicality, and has broad application prospects.
