Description

Technical Field

[0001] This utility model relates to the field of polyethylene glycol production technology, and in particular to a cryo-slicing machine for polyethylene glycol production. Background Technology

[0002] A cryostat is a device used in polyethylene glycol (PEG) production to freeze and slice PEG solutions. When using a cryostat, the PEG solution is poured into the telescopic sleeve. The control panel then freezes the PEG solution. After freezing, a second servo motor drives a second threaded rod to rotate. Under the constraint of a second limit rod, the frozen PEG is squeezed out of the telescopic sleeve. A first servo motor then drives a first threaded rod to rotate, and under the constraint of the first limit rod, the PEG is effectively sliced ​​by a cutter.

[0003] The inventors discovered in their daily work that cryostats still have at least the following problems: When using a cryostat, polyethylene glycol (PEG) solution is poured into the telescopic sleeve, and then the cryostat body is controlled via the control panel to freeze the PEG solution. After freezing, the second servo motor drives the second threaded rod to rotate, and under the limitation of the second limit rod, the frozen PEG is squeezed out of the telescopic sleeve. Then, the first servo motor drives the first threaded rod to rotate, and under the limitation of the first limit rod, the PEG can be sliced ​​well by the cutter. However, in actual use, because the cutter is set on the surface of the first threaded rod, the cutter becomes dull after long-term use, making it difficult to sharpen the cutter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cryo-slicing machine for polyethylene glycol production.

A connecting device is provided at the top. A second servo motor is fixedly connected to the bottom of the inner wall of the cryostat body. A second threaded rod is fixedly connected to the output end of the second servo motor. A second limiting rod is fixedly connected to the inner wall of the cryostat body. A moving plate is threadedly fitted onto the surface of the second threaded rod. The moving plate is slidably fitted onto the surface of the second limiting rod. A telescopic sleeve is fixedly connected to the top of the moving plate. The top of the telescopic sleeve is fixedly connected to the top of the cryostat body. The fixing device includes a connecting plate. A first connecting groove is opened on one side of the first connecting frame. The inner wall of the first connecting groove is slidably connected to the connecting plate. The connecting plate is fixedly connected to one side of the cutter.

[0006] The effect achieved by the above components is as follows: when using the fixing device, the connecting plate is manually passed through the inside of the first connecting groove opened on one side of the first connecting frame, and then the rubber block is squeezed through the first connecting groove.

[0010] The effect achieved by the above components is that the L-shaped plate is pulled towards the first connecting frame by the first spring, which can effectively confine the L-shaped plate inside the fixing groove.

[0011] Preferably, a support plate is uniformly fixedly connected to the side of the first connecting frame away from the first threaded rod, and a second damping rod is fixedly connected to the side of the support plate close to the body of the cryostat.

A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to one side of the support plate, and the end of the second spring close to the second damping rod is fixedly connected to one side of the compression plate.

[0015] Preferably, an elastic frame is fixedly connected to the top of the second connecting frame, and the top of the elastic frame is fixedly connected to the bottom of the connecting cover.

[0016] The effect achieved by the above components is that the elastic frame can effectively change the internal volume of the connecting cover, thereby effectively adsorbing the connecting cover onto the top of the cryostat body.

[0017] Preferably, a connecting strip is fixedly connected to the top of the connecting cover, a third damping rod is fixedly connected to the bottom of the connecting strip away from the connecting cover, a support block is rotatably sleeved on the bottom of the third damping rod, one side of the support block is fixedly connected to one side of the cryostat body, a third spring is sleeved on the surface of the third damping rod, the bottom of the third spring is fixedly connected to the surface of the third damping rod near the bottom of the support block, and the end of the third spring near the third damping rod is fixedly connected to the bottom of the connecting strip.

[0018] The effect achieved by the above components is that the connecting strip is pulled towards the top of the cryostat body by the third spring, which can effectively cover the top of the cryostat body.

[0019] Preferably, a fourth damping rod is fixedly connected to the bottom of the support block, and a U-shaped plate is fixedly connected to the bottom of the fourth damping rod.

[0020] The effect achieved by the above components is that the U-shaped plate is pulled towards the support block by the fourth spring, so that the U-shaped plate slides into the bottom of the connecting strip, thus preventing the connecting strip from rotating to a certain extent.

[0021] In this utility model, by setting a fixing device, when using the fixing device, the connecting plate is manually passed through the inside of the first connecting groove opened on one side of the first connecting frame, and then the rubber block is squeezed through the first connecting groove. This can effectively set the cutter on one side of the first connecting frame, which makes it easy to disassemble the cutter and make it easy to grind the cutter. Attached Figure Description

The top of the telescopic sleeve 12 is fixedly connected to the top of the cryostat body 1. When using the cryostat, the polyethylene glycol solution is poured into the inside of the telescopic sleeve 12. Then, the cryostat body 1 is controlled by the operation panel 2 to freeze the polyethylene glycol solution. After freezing, the second servo motor 10 is controlled to drive the second threaded rod 11 to rotate. Under the limitation of the second limiting rod 14, the frozen polyethylene glycol is squeezed out of the telescopic sleeve 12.

[0028] Reference Figure 2 and Figure 3The fixing device 6 includes a connecting plate 601. A first connecting groove 602 is provided on one side of the first connecting frame 4. The inner wall of the first connecting groove 602 is slidably connected to the connecting plate 601. The connecting plate 601 is fixedly connected to one side of the cutter 5. A rubber block 603 is fixedly connected to the end of the connecting plate 601 away from the cutter 5. When using the fixing device 6, the connecting plate 601 is manually passed through the interior of the first connecting groove 602 on one side of the first connecting frame 4, thereby squeezing the rubber block 603 through the first connecting groove 602. This can effectively position the cutter 5 on one side of the first connecting frame 4. To facilitate disassembly and grinding of the cutter 5, a fixing groove 604 is provided on the top of the connecting plate 601. An L-shaped plate 607 is slidably connected to the inner wall of the fixing groove 604. Sliding the L-shaped plate 607 into the fixing groove 604 effectively confines the connecting plate 601 within the first connecting groove 602. A first damping rod 605 is fixedly connected to the top of the first connecting frame 4. The top of the first damping rod 605 is fixedly connected to one side of the L-shaped plate 607.

The top of frame 4 is fixedly connected to a first spring 606. One end of the first spring 606 near the first damping rod 605 is fixedly connected to the bottom of one side of the L-shaped plate 607. The first spring 606 pulls the L-shaped plate 607 towards the first connecting frame 4, thus effectively confining the L-shaped plate 607 inside the fixing groove 604. A support plate 608 is evenly fixedly connected to the side of the first connecting frame 4 away from the first threaded rod 8. A second damping rod 609 is fixedly connected to the side of the support plate 608 near the main body 1 of the cryostat.

One end of the second spring 610 is fixedly connected to one side of the support plate 608, and the end of the second spring 610 near the second damping rod 609 is fixedly connected to one side of the extrusion plate 611. By extruding the extrusion plate 611 away from the support plate 608 through the second spring 610, the extrusion plate 611 can be effectively confined between the rubber block 603 and the first connecting frame 4, thereby effectively confining the connecting plate 601 inside the first connecting groove 602.

[0029] Reference Figure 4The connecting device 7 includes a second connecting frame 707. A second connecting groove 709 is provided on the top of the cryostat body 1. The inner wall of the second connecting groove 709 is slidably connected to the second connecting frame 707. A rubber frame 708 is fixedly connected to the bottom of the second connecting frame 707. A connecting cover 705 is provided on the top of the second connecting frame 707. When using the connecting device 7, the second connecting frame 707 is manually slid into the second connecting groove 709, thereby placing the connecting cover 705 on the top of the cryostat body 1. This effectively prevents cold air from evaporating from the top of the cryostat body 1. To accelerate the freezing speed of polyethylene glycol to a certain extent, a spring frame 706 is fixedly connected to the top of the second connecting frame 707. The top of the spring frame 706 is fixedly connected to the bottom of the connecting cover 705. The spring frame 706 can effectively change the internal volume of the connecting cover 705, thereby effectively adsorbing the connecting cover 705 onto the top of the cryostat body 1. A connecting strip 704 is fixedly connected to the top of the connecting cover 705. A third damping rod 702 is fixedly connected to the bottom of the end of the connecting strip 704 away from the connecting cover 705. A support block 701 is rotatably sleeved on the bottom of the third damping rod 702. One side of the support block 701 is fixedly connected to one side of the cryostat body 1. A third spring 703 is sleeved on the surface of the third damping rod 702. The bottom of the third spring 703 is fixedly connected to the bottom surface of the third damping rod 702 near the support block 701. The end of the third spring 703 near the third damping rod 702 is fixedly connected to the bottom of the connecting strip 704. The connecting strip 704 is pulled towards the top of the cryostat body 1 by the third spring 703, so that the connecting cover 705 can be properly covered on the top of the cryostat body 1. A fourth damping rod 710 is fixedly connected to the bottom of the support block 701. A U-shaped plate 712 is fixedly connected to the bottom of the fourth damping rod 710. The U-shaped plate 712 is slidably inserted into the bottom of the connecting bar 704. A fourth spring 711 is sleeved on the surface of the fourth damping rod 710. The top of the fourth spring 711 is fixedly connected to the bottom of the support block 701. One end of the fourth spring 711 near the fourth damping rod 710 is fixedly connected to one side of the U-shaped plate 712. By pulling the U-shaped plate 712 towards the support block 701 through the fourth spring 711, the U-shaped plate 712 is slidably inserted into the bottom of the connecting bar 704, which to a certain extent prevents the connecting bar 704 from rotating.

[0030] Working principle: When using the cryostat, the polyethylene glycol solution is poured into the telescopic sleeve 12. The cryostat body 1 is then controlled via the control panel 2 to freeze the polyethylene glycol solution. After freezing, the second servo motor 10 drives the second threaded rod 11 to rotate. Under the limitation of the second limiting rod 14, the frozen polyethylene glycol is squeezed out of the telescopic sleeve 12. Then, the first servo motor 3 drives the first threaded rod 8 to rotate. Under the restriction of the first limiting rod 9, the polyethylene glycol can be effectively sliced ​​by the cutter 5. The fixing device 6 is used. When manually inserting the connecting plate 601 through the first connecting groove 602 on one side of the first connecting frame 4, the rubber block 603 is squeezed through the first connecting groove 602, and the L-shaped plate 607 is slid into the fixing groove 604. The L-shaped plate 607 is pulled towards the first connecting frame 4 by the first spring 606, which can effectively restrict the L-shaped plate 607 inside the fixing groove 604. The pressing plate 611 is pressed away from the support plate 608 by the second spring 610, which can effectively restrict the pressing plate 611 between the rubber block 603 and the first connecting frame 4. The connecting frame 4 is positioned in the middle, thus effectively confining the connecting plate 601 inside the first connecting groove 602. This allows the cutter 5 to be positioned on one side of the first connecting frame 4, facilitating its removal and grinding. When using the connecting device 7, the connecting strip 704 is pulled towards the top of the cryostat body 1 by the third spring 703, effectively covering the top of the cryostat body 1 with the connecting cover 705. This slides the second connecting frame 707 into the second connecting groove 709, and the elastic frame 706 effectively... By changing the internal volume of the connecting cover 705, the connecting cover 705 can be effectively adsorbed onto the top of the cryostat body 1. By placing the connecting cover 705 on the top of the cryostat body 1, cold air can be effectively prevented from evaporating from the top of the cryostat body 1. This can accelerate the freezing speed of polyethylene glycol to a certain extent. The fourth spring 711 pulls the U-shaped plate 712 towards the support block 701, so that the U-shaped plate 712 slides and is inserted into the bottom of the connecting strip 704, which can prevent the connecting strip 704 from rotating to a certain extent.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
