Description

Technical Field

[0001] The present invention relates to the field of transmission technology, and in particular to a transmission mechanism, a linear forming device and a high-level radioactive liquid waste glass sample preparation system. Background Art

[0002] Currently, existing transmission structures require a separate set of actuators to simultaneously perform other operations while transmitting. These actuators are equipped with independent power and control systems. To ensure coordinated operation of these components, the synergy and coordination between the transmission and actuators must be precisely controlled. This significantly increases the requirements for synchronous and coordinated control, often making the entire system more complex.

[0003] In view of this, this application is hereby filed. Summary of the Invention

[0004] The first purpose of the present invention is to provide a transmission mechanism that can simultaneously achieve precise control of the execution component while realizing transmission, further improving the coordinated matching between the transmission and the execution component, and the required power source is simpler and the structure is more streamlined.

[0006] The third object of the present invention is to provide a high-level radioactive liquid waste glass sampling system, which can continuously monitor the molding accuracy while sampling nuclear waste glass, thereby greatly improving the sampling quality.

[0007] The embodiment of the present invention is achieved as follows:

[0012] One end of the first engaging rod engages with the engaging hole. Along the axial direction of the first engaging rod, the first engaging rod slides with the second engaging rod, and the first engaging rod is fixedly mounted to the frame. Along the circumferential direction of the first engaging rod, the first engaging rod is fixedly engaged with the second engaging rod, and the first engaging rod is rotatably mounted to the frame.

[0013] The end face of the driving shaft is arranged toward the side wall of the first cooperating rod, and the driving shaft and the first cooperating rod are spaced apart. The rotation axis centers of the first cooperating rod and the driving shaft are perpendicular to each other and coplanar.

[0014] A rotating member is provided at one end of the first cooperating rod away from the second cooperating rod, and the rotation axis of the rotating member is perpendicular to the plane where the rotation axes of the first cooperating rod and the driving shaft are located, and the rotation axis of the rotating member intersects with the rotation axis of the first cooperating rod.

[0015] One end of the first extension rod is fixedly connected to the end of the driving shaft, and the other end extends toward the side where the first matching rod is located. The angle between the first extension rod and the driving shaft is greater than 0° and less than 90°.

[0016] One end of the first connecting rod is rotatably engaged with the end of the first extension rod away from the drive shaft and is arranged perpendicular to the first extension rod, and the other end is fixedly connected to the rotating member. The central axis of the first connecting rod is arranged perpendicular to the rotation axis of the rotating member and intersects the rotation axis of the first engaging rod.

[0017] The first driving wheel is used to transmit power outward, and the end of the second cooperating rod away from the first cooperating rod is used to install the execution component, so that during the rotation of the driving shaft, the transmission mechanism can provide power outward through the first driving wheel, and enable the execution component to periodically move away from and approach the target area to complete the corresponding execution steps.

[0018] Furthermore, the transmission mechanism also includes: a driven shaft, a second driving wheel, a second extension rod and a second connecting rod.

[0019] The driven shaft is installed on the frame, the second driving wheel is coaxially fixedly connected to the driven shaft, the driven shaft and the driving shaft are coaxial and spaced apart, and are respectively arranged on opposite sides of the first matching rod.

[0020] The second extension rod is located on the side of the second driving wheel close to the driving shaft. One end of the second extension rod is fixedly connected to the driven shaft, and the other end extends toward the side where the first matching rod is located. The angle between the second extension rod and the driven shaft is greater than 0° and less than 90°.

[0021] One end of the second connecting rod is rotatably engaged with the end of the second extension rod distal from the driven shaft and is disposed perpendicularly to the second extension rod, while the other end is fixedly connected to the rotating member. The second connecting rod and the first connecting rod are coaxially disposed and disposed on opposite sides of the rotating member. The central axis of the second connecting rod is perpendicular to the rotational axis of the rotating member and intersects the rotational axis of the first mating rod.

[0022] The second driving wheel is used to transmit power outward, so that during the rotation of the driving shaft, the driving shaft can drive the driven shaft through the first extension rod, the first connecting rod, the rotating member, the second connecting rod and the second extension rod, thereby enabling the second driving wheel to provide power outward.

[0023] Furthermore, the transmission mechanism also includes: an air supply component.

[0024] The mating sleeve defines a first channel and a second channel. The first channel is formed by the inner wall of the mating sleeve along its radial direction, while the second channel is formed by the inner wall of the first channel along its axial direction. The end of the second channel, remote from the first channel, extends through the outer surface of the mating sleeve. The end of the second channel, remote from the first channel, is connected to the air supply assembly.

[0025] A mating post is positioned within the first channel. It slidably engages the first channel along its length. An elastic member abuts between the end of the mating post facing away from the second mating rod and the end of the first channel facing away from the second mating rod. An axial hole is defined in the end surface of the mating post near the second mating rod, and a notch is defined in the sidewall of the mating post, which communicates with the axial hole. A sliding seal is formed between the mating post and the first channel.

[0026] The inner side wall of the mating sleeve is also provided with a dust exhaust channel, which is arranged on opposite sides of the inner side wall of the mating sleeve and corresponds to the first channel. One end of the dust exhaust channel is located on the inner side wall of the mating sleeve, and the other end is located on the end wall of the mating sleeve near the first mating rod.

[0027] When the second matching rod reaches the closest point to the target area, the second matching rod pushes the matching column into the first channel, the connecting notch is staggered with the second channel, and the connecting notch is disconnected from the second channel.

[0028] When the second cooperating rod reaches a point far from the target area, the end face of the second cooperating rod is located on the side of the first channel close to the first cooperating rod, the cooperating column is pushed out of the first channel by the elastic member, the connecting notch is aligned with the second channel, and the connecting notch is connected to the second channel, so that the air supply component can use the airflow to clean the end face of the second cooperating rod.

[0029] Furthermore, the air supply assembly includes: a first pulley, a second pulley, a third pulley, a fourth pulley and a push rod.

[0030] The first pulley is coaxially and fixedly connected to the driven shaft.

[0031] An air cavity is defined on the end face of the driven shaft remote from the driving shaft. The air cavity extends axially along the driven shaft. A moving member is housed within the air cavity. The moving member is fixedly engaged with the driven shaft along its circumferential direction. A sliding seal is formed between the moving member and the driven shaft. A push rod is fixedly connected to the moving member and extends beyond the driven shaft. The air cavity is connected to the second passageway via a connecting pipe.

[0032] The fourth pulley is coaxial with the first pulley and spaced apart from the first pulley. The fourth pulley is located on a side of the first pulley away from the driving shaft.

[0033] The second pulley, the third pulley and the fourth pulley are all rotatably matched with the frame. The second pulley and the third pulley are coaxially fixedly connected, the second pulley and the first pulley are arranged in parallel, and the third pulley and the fourth pulley are arranged in parallel.

[0034] The second pulley and the first pulley are matched with each other through a synchronous belt transmission, and the third pulley and the fourth pulley are matched with each other through a synchronous belt transmission.

[0035] The second pulley and the third pulley have the same diameter, and the diameter of the first pulley is larger than the diameter of the fourth pulley.

[0036] The fourth pulley has a mating through hole coaxially disposed with the fourth pulley and having an internal thread. The push rod has an external thread that engages with the mating through hole, so that the fourth pulley can drive the push rod to move into the driven shaft during rotation of the drive shaft.

[0037] Furthermore, the first driving wheel is used to cooperate with the conveyor belt transmission. The execution component includes: at least one of: a distance sensor, a pressure sensor, a code sprayer, a labeling machine and a push arm.

[0038] A linear forming device comprises a guide rail, a base plate, a mould and the above-mentioned transmission mechanism.

[0039] The base plate is slidably matched with the guide rail. A rack is provided at the bottom of the base plate along the length direction of the base plate. The first driving wheel has an outer gear ring. The first driving wheel is meshed with the rack.

[0040] The upper surface of the substrate is provided with a placement area for placing the mold.

[0041] The placement area is provided with a clearance gap which penetrates the base plate, and the clearance gap extends along the length direction of the base plate.

[0042] The execution component includes a pressure sensor, which is arranged on an end surface of the second mating rod away from the first mating rod.

[0043] When the second cooperating rod reaches the closest point to the target area, it extends through the clearance notch toward the placement area, so that the detection surface of the pressure sensor is higher than the bottom surface of the placement area. When the second cooperating rod reaches the furthest point from the target area, the detection surface of the pressure sensor is lower than the bottom surface of the placement area.

[0044] Furthermore, the plurality of placement areas are evenly spaced along the length direction of the substrate, each placement area is provided with a clearance gap, and the clearance gaps of two adjacent placement areas are spaced apart.

[0045] Furthermore, when the second mating rod reaches a point far from the target area, the mating sleeve is located in the area between the clearance notches of two adjacent placement areas.

[0046] Furthermore, the placement area is adapted to the mold, and the edge of the placement area is provided with hemispherical convex points, and a plurality of convex points are evenly spaced along the edge of the placement area.

[0047] A high-level radioactive liquid waste glass sample preparation system comprises a melting mechanism, a discharging mechanism and the above-mentioned linear forming device.

[0048] The melting mechanism is used to heat the nuclear waste glass to a molten state, and the discharging mechanism is used to put the nuclear waste glass in a molten state in the melting mechanism into the mold of the linear forming device.

[0049] The driving shaft is used to drive the substrate to move so that the molds are transported to the discharge mechanism in sequence, so that the molds can take on the nuclear waste glass in a molten state in sequence.

[0050] The beneficial effects of the technical solution of the embodiment of the present invention include:

[0051] During operation of the transmission mechanism provided by an embodiment of the present invention, driven by the drive shaft, the first drive wheel not only transmits power, but also causes the first cooperating rod to reciprocate. This reciprocating rotation of the first cooperating rod also drives the second cooperating rod to reciprocate. This reciprocating rotation of the second cooperating rod causes the second cooperating rod to reciprocate along the axial direction of the cooperating sleeve, meaning that the second cooperating rod can "extend" and "retract" relative to the cooperating sleeve. This allows the second cooperating rod to drive the actuator forward and backward, allowing the actuator to periodically approach and move away from the target area to complete the corresponding operation.

[0052] In general, the transmission mechanism provided by the embodiment of the present invention can achieve precise control of the execution component while realizing transmission, further improving the coordinated matching between the transmission and the execution component, and the required power source is simpler and the structure is more streamlined.

[0053] The linear forming device provided by the embodiment of the present invention can continuously monitor the forming accuracy while forming, thereby greatly improving the forming quality.

[0054] The high-level radioactive liquid waste glass sampling system provided in the embodiment of the present invention can continuously monitor the molding accuracy while sampling nuclear waste glass, thereby greatly improving the sampling quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0073] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0074] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0075] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0076] Furthermore, the terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular," not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0077] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0078] In order to overcome the shortcomings of the existing technology, please refer to Figure 1-Figure 2 This embodiment provides a transmission mechanism 1000, which includes: a frame (not shown in the figure), a drive shaft 100, a first drive wheel 110, a first extension rod 120, a first connecting rod 130, a first matching rod 210, a second matching rod 220 and a matching sleeve 230.

[0079] The drive shaft 100 is mounted on the frame. The drive shaft 100 can rotate relative to the frame, but cannot move axially.

[0080] The first driving wheel 110 is coaxially and fixedly connected to the driving shaft 100 .

[0081] The matching sleeve 230 is fixedly mounted on the frame, and the central axis of the matching sleeve 230 is perpendicular to the driving shaft 100. The matching sleeve 230 has an internal thread.

[0082] The second mating rod 220 has an external thread, and one end of the second mating rod 220 is threadedly engaged with the mating sleeve 230. The second mating rod 220 is arranged perpendicular to the drive shaft 100, and an end surface of the second mating rod 220 away from the mating sleeve 230 is provided with a mating hole arranged along its axial direction.

[0083] The first mating rod 210 is disposed along the length direction of the second mating rod 220 . One end of the first mating rod 210 is engaged with the mating hole. The first mating rod 210 is perpendicular to the driving shaft 100 .

[0084] Along the axial direction of the first mating rod 210 , the first mating rod 210 and the second mating rod 220 are slidably engaged. The first mating rod 210 is fixedly mounted on the frame, that is, the first mating rod 210 cannot move axially.

[0085] Along the circumference of the first cooperating rod 210 , the first cooperating rod 210 is fixedly matched with the second cooperating rod 220 . The first cooperating rod 210 is rotatably mounted on the frame, that is, the first cooperating rod 210 can rotate.

[0086] The end face of the drive shaft 100 faces the side wall of the first mating rod 210, and the drive shaft 100 is spaced apart from the first mating rod 210. The rotation axes of the first mating rod 210 and the drive shaft 100 are perpendicular to each other and coplanar.

[0087] A rotating member 211 is provided at one end of the first cooperating rod 210 away from the second cooperating rod 220. The rotation axis of the rotating member 211 is perpendicular to the plane where the rotation axes of the first cooperating rod 210 and the driving shaft 100 are located, and the rotation axis of the rotating member 211 intersects with the rotation axis of the first cooperating rod 210.

[0088] The first extension rod 120 is located on the side of the first drive wheel 110 near the first mating rod 210. One end of the first extension rod 120 is fixedly connected to the end of the drive shaft 100, and the other end extends toward the side where the first mating rod 210 is located. In other words, the other end of the first extension rod 120 extends away from the first drive wheel 110. The angle between the first extension rod 120 and the drive shaft 100 is greater than 0° and less than 90°. In other words, the first extension rod 120 is neither parallel to nor perpendicular to the drive shaft 100. Optionally, the angle between the first extension rod 120 and the drive shaft 100 is 60°, but the angle is not limited thereto.

[0089] One end of the first connecting rod 130 is rotatably engaged with the end of the first extension rod 120 away from the drive shaft 100 and is disposed perpendicularly to the first extension rod 120. The other end of the first connecting rod 130 extends to the rotating member 211 and is fixedly connected to the rotating member 211. The central axis of the first connecting rod 130 is disposed perpendicularly to the rotational axis of the rotating member 211, and the central axis of the first connecting rod 130 intersects the rotational axis of the first engaging rod 210.

[0090] The drive shaft 100 is a power input end of the transmission mechanism 1000 . The drive shaft 100 is driven by a driver (not shown in the figure), and the driver transmits power through the transmission mechanism 1000 .

[0091] The first drive wheel 110 is used to transmit power outward. The first drive wheel 110 can achieve power transmission through tooth transmission, belt transmission, etc., but is not limited thereto. The first drive wheel 110 can be used to cooperate with a conveyor belt transmission, or can be used to cooperate with other gear transmissions, but is not limited thereto.

[0092] The end of the second cooperating rod 220 away from the first cooperating rod 210 is used to install an actuator (not shown in the figure). In this way, when the drive shaft 100 is driven by the driver, the drive shaft 100 rotates, and the first drive wheel 110 rotates synchronously with the drive shaft 100 to realize power transmission. At the same time, the first extension rod 120 moves synchronously with the drive shaft 100, and the end of the first extension rod 120 away from the drive shaft 100 moves along a circular trajectory. The first extension rod 120 drives the first connecting rod 130, and the first connecting rod 130 will drive the rotating member 211 to rotate back and forth along its rotation axis, and at the same time, it will also cause the first cooperating rod 210 to rotate back and forth along its rotation axis.

[0093] In other words, driven by the drive shaft 100, the first drive wheel 110 not only transmits power, but also causes the first cooperating rod 210 to reciprocate. This reciprocating rotation of the first cooperating rod 210 also drives the second cooperating rod 220 to reciprocate. This reciprocating rotation causes the second cooperating rod 220 to reciprocate along the axial direction of the cooperating sleeve 230, effectively extending and retracting the second cooperating rod 220 relative to the cooperating sleeve 230. This allows the second cooperating rod 220 to move forward and backward, allowing the actuator to periodically approach and retreat from a target area to complete the corresponding operation.

[0094] The execution component may be at least one of a distance sensor, a pressure sensor, an inkjet printer, a labeler, and a push arm, and is not limited thereto.

[0095] In general, the transmission mechanism 1000 provided in this embodiment can achieve precise control of the execution component while realizing transmission, further improving the coordination and matching between the transmission and the execution component, and the required power source is simpler and the structure is more streamlined.

[0096] Furthermore, the transmission mechanism 1000 further includes: a driven shaft 300 , a second driving wheel 330 , a second extension rod 340 and a second connecting rod 350 .

[0097] The driven shaft 300 is mounted on the frame. The driven shaft 300 can rotate relative to the frame, but cannot move axially.

[0098] The second driving wheel 330 is coaxially fixedly connected to the driven shaft 300 . The driven shaft 300 and the driving shaft 100 are coaxially arranged and spaced apart. The driven shaft 300 and the driving shaft 100 are respectively arranged on opposite sides of the first matching rod 210 .

[0099] The second extension rod 340 is located on the side of the second drive wheel 330 close to the drive shaft 100. One end of the second extension rod 340 is fixedly connected to the driven shaft 300, and the other end of the second extension rod 340 extends toward the side where the first matching rod 210 is located. The angle between the second extension rod 340 and the driven shaft 300 is greater than 0° and less than 90°. In other words, the second extension rod 340 is neither parallel to the driven shaft 300 nor perpendicular to the driven shaft 300. The "angle between the second extension rod 340 and the driven shaft 300" is the same as the "angle between the first extension rod 120 and the drive shaft 100". Optionally, the angle between the second extension rod 340 and the driven shaft 300 is 60°, but is not limited thereto.

[0100] Taking the rotation axis of the driving shaft 100 or the rotation axis of the driven shaft 300 as a reference line, the first extension rod 120 and the second extension rod 340 are respectively disposed on opposite sides of the reference line.

[0101] One end of the second connecting rod 350 is rotatably engaged with one end of the second extension rod 340 away from the driven shaft 300 and is arranged perpendicular to the second extension rod 340 . The other end of the second connecting rod 350 extends to the rotating member 211 , and the second connecting rod 350 is fixedly connected to the rotating member 211 .

[0102] The second connecting rod 350 and the first connecting rod 130 are coaxially arranged and disposed on opposite sides of the rotating member 211 . The central axis of the second connecting rod 350 is perpendicular to the rotation axis of the rotating member 211 and intersects with the rotation axis of the first matching rod 210 .

[0103] The second drive wheel 330 is also used to transmit power outward. During the rotation of the drive shaft 100, the drive shaft 100 can drive the driven shaft 300 through the first extension rod 120, the first connecting rod 130, the rotating member 211, the second connecting rod 350, and the second extension rod 340, causing the driven shaft 300 to rotate synchronously with the drive shaft 100, thereby enabling the second drive wheel 330 to provide power outward.

[0104] With this design, the transmission mechanism 1000 can have more power output and can effectively improve the stability of the first cooperating rod 210 and the second cooperating rod 220 .

[0105] In this embodiment, the transmission mechanism 1000 further includes: an air supply component.

[0106] Please combine Figure 3-Figure 5 The matching sleeve 230 defines a first channel 231 and a second channel 232 .

[0107] The first channel 231 is formed by the inner wall of the mating sleeve 230 along the radial direction of the mating sleeve 230. The second channel 232 is formed by the inner wall of the first channel 231 along the axial direction of the mating sleeve 230. The end of the second channel 232 away from the first channel 231 extends through the outer surface of the mating sleeve 230. The end of the second channel 232 away from the first channel 231 is used to communicate with the air supply assembly.

[0108] A mating post 240 is housed within the first channel 231. The mating post 240 slidably engages the first channel 231 along its length. An elastic member 243 abuts between the end of the mating post 240 facing away from the second mating rod 220 and the end of the first channel 231 facing away from the second mating rod 220. An axial hole 241 is defined on the end surface of the mating post 240 proximal to the second mating rod 220. A connecting notch 242 is also defined on the sidewall of the mating post 240, communicating with the axial hole 241. A sliding seal forms between the mating post 240 and the first channel 231.

[0109] The inner sidewall of the mating sleeve 230 also defines a dust exhaust passage 233. Dust exhaust passage 233 and first passage 231 are located on opposite sides of the inner sidewall of the mating sleeve 230 and correspond to each other. One end of dust exhaust passage 233 is located on the inner sidewall of the mating sleeve 230, and the other end is located on the end wall of the mating sleeve 230 near the first mating rod 210.

[0110] When the second mating rod 220 reaches the closest point to the target area (ie, when the extended length of the second mating rod 220 relative to the mating sleeve 230 reaches the maximum), Figure 4 As shown, the second engaging rod 220 pushes the engaging column 240 into the first channel 231 , the communicating notch 242 is staggered with the second channel 232 , and the communicating notch 242 is disconnected from the second channel 232 .

[0111] When the second engagement rod 220 reaches a point far from the target area (ie, when the second engagement rod 220 is fully retracted relative to the engagement sleeve 230), Figure 5 As shown, the end face of the second mating rod 220 is located on the side of the first channel 231 close to the first mating rod 210. The mating post 240 is pushed out of the first channel 231 by the elastic member 243. The connecting notch 242 is aligned with the second channel 232, and the connecting notch 242 is connected to the second channel 232. At this time, the air supply assembly can deliver air to the end face of the second mating rod 220 through the second channel 232, the connecting notch 242, and the axial hole 241, so that the air supply assembly can use the airflow to clean the end face of the second mating rod 220, and dust and impurities that may be present on the end face of the second mating rod 220 can be discharged through the dust exhaust channel 233.

[0112] In the process of the second cooperating rod 220 moving away from the far point from the target area and toward the near point from the target area, the second cooperating rod 220 pushes the cooperating column 240 into the first channel 231, and finally the connecting gap 242 is staggered with the second channel 232, and the connecting gap 242 is disconnected from the second channel 232.

[0113] Through this design, the end surface of the second mating rod 220 and the actuator assembly mounted on the end surface of the second mating rod 220 are cleaned.

[0114] Specifically, the air supply assembly includes: a first pulley 410 , a second pulley 420 , a third pulley 430 , a fourth pulley 440 and a push rod 450 .

[0115] The first pulley 410 is coaxially and fixedly connected to the driven shaft 300 .

[0116] An air cavity 310 is formed on one end surface of the driven shaft 300 away from the driving shaft 100. The air cavity 310 extends along the axial direction of the driven shaft 300. A moving part 320 is accommodated in the air cavity 310.

[0117] The moving member 320 is fixedly fitted to the driven shaft 300 along the circumferential direction of the driven shaft 300. The moving member 320 is slidably fitted to the driven shaft 300 along the axial direction of the driven shaft 300. A sliding seal is formed between the moving member 320 and the driven shaft 300.

[0118] The push rod 450 is fixedly connected to the moving member 320 and extends outside the driven shaft 300. The air cavity 310 is connected to the second channel 232 via a connecting pipe (not shown).

[0119] The fourth pulley 440 is coaxial with the first pulley 410 and spaced apart from each other. The fourth pulley 440 is located on a side of the first pulley 410 away from the driving shaft 100 .

[0120] The second pulley 420, the third pulley 430, and the fourth pulley 440 are all rotatably coupled to the frame. The second pulley 420, the third pulley 430, and the fourth pulley 440 are all rotatable and cannot move axially.

[0121] The second pulley 420 and the third pulley 430 are coaxially fixedly connected. The second pulley 420 and the first pulley 410 are arranged in parallel, and the third pulley 430 and the fourth pulley 440 are arranged in parallel.

[0122] The second pulley 420 and the first pulley 410 are coupled to each other through a synchronous belt transmission, and the third pulley 430 and the fourth pulley 440 are coupled to each other through a synchronous belt transmission.

[0123] The second pulley 420 and the third pulley 430 have the same diameter, and the diameter of the first pulley 410 is greater than the diameter of the fourth pulley 440 .

[0124] The fourth pulley 440 defines a mating through hole coaxially disposed with the fourth pulley 440 and having an internal thread. The push rod 450 has an external thread and is threadably engaged with the mating through hole, so that when the drive shaft 100 rotates, the fourth pulley 440 can drive the push rod 450 to move inwardly of the driven shaft 300.

[0125] When the driving shaft 100 rotates, the driven shaft 300 rotates synchronously therewith, and the first pulley 410 rotates synchronously with the driven shaft 300 . The first pulley 410 drives the second pulley 420 and the third pulley 430 , and the third pulley 430 drives the fourth pulley 440 .

[0126] Assume that the radius of first pulley 410 is r1, the radius of fourth pulley 440 is r4, and the angular velocity of the driven pulley during rotation is ω. Accordingly, the angular velocity of first pulley 410 is ω, and the linear velocity of first pulley 410 is ω·r1. After transmission through the synchronous belt, the linear velocity of fourth pulley 440 is ω·r1, and the angular velocity of fourth pulley 440 is (ω·r1) / r4. Since r1>r4, (ω·r1) / r4 is greater than ω, which means that the angular velocity of fourth pulley 440 is greater than that of first pulley 410.

[0127] Based on this, there is an angular velocity difference between the first pulley 410 and the fourth pulley 440. Since the rotational angular velocity of the push rod 450 is the same as the rotational angular velocity of the first pulley 410, there is a relative rotation between the push rod 450 and the fourth pulley 440, and the fourth pulley 440 can drive the push rod 450 to move axially through the thread.

[0128] The threads between the push rod 450 and the fourth pulley 440 are configured such that when the drive shaft 100 rotates in a predetermined direction, the push rod 450 and the fourth pulley 440 rotate relative to each other, driving the push rod 450 into the air cavity 310 of the driven shaft 300. During this process, the moving member 320 compresses the gas within the air cavity 310, increasing the gas pressure therein. Each time the second mating rod 220 reaches a point far from the target area, the air supply assembly utilizes pressurized airflow to clean the end surface of the second mating rod 220, thereby enhancing the cleaning effect.

[0129] Please combine Figures 6-10 This embodiment further provides a linear forming device 2000 , which includes: a guide rail 2100 , a base plate 2200 , a mold 2300 and the above-mentioned transmission mechanism 1000 .

[0130] The base plate 2200 is slidably fitted in the guide rail 2100. A rack 2210 is provided at the bottom of the base plate 2200 along the length direction of the base plate 2200. In this embodiment, racks 2210 are provided on both sides of the bottom of the base plate 2200. The first drive wheel 110 and the second drive wheel 330 have the same outer diameter. The first drive wheel 110 and the second drive wheel 330 both have outer gear rings. The first drive wheel 110 and the second drive wheel 330 are respectively engaged with the racks 2210 on both sides of the bottom of the base plate 2200.

[0131] The upper surface of the substrate 2200 is provided with a placement area 2220 for placing the mold 2300 .

[0132] The placement area 2220 is provided with a clearance notch 2230 penetrating the base plate 2200 . The clearance notch 2230 extends along the length direction of the base plate 2200 . The width of the clearance notch 2230 is greater than the outer diameter of the second matching rod 220 .

[0133] The actuator assembly includes a pressure sensor (not shown in the figure), which is provided on an end surface of the second mating rod 220 away from the first mating rod 210 .

[0134] When the second cooperating rod 220 reaches the closest point to the target area, Figure 10 As shown, the second cooperating rod 220 extends into the placement area 2220 via the clearance notch 2230, so that the detection surface of the pressure sensor is slightly higher than the bottom surface of the placement area 2220. In this way, the second cooperating rod 220 can use the pressure sensor to slightly lift the mold 2300 placed in the placement area 2220. This facilitates the pressure sensor to detect the weight of the mold 2300, thereby helping to determine whether there is any material remaining in the empty mold 2300 or to determine whether the weight of the material in the mold 2300 filled with material meets the required standard. Because the pressure sensor only slightly lifts the mold 2300 placed in the placement area 2220, it can prevent the mold 2300 from tipping over.

[0135] When the second cooperating rod 220 moves to a point far from the target area, as shown in FIG. Figure 11 As shown, the pressure sensor can then be separated from the bottom of the mold 2300. When the second mating rod 220 reaches a point far from the target area, the detection surface of the pressure sensor is lower than the bottom surface of the placement area 2220. This prevents the pressure sensor from obstructing the normal movement of the substrate 2200 and reduces mechanical wear on the pressure sensor.

[0136] While realizing the transportation of the mold 2300, the linear forming device 2000 can also be used to detect whether there is any material residue in the mold 2300, or whether the weight of the material in the mold 2300 filled with material meets the standard. While the molding process is in progress, the weight of the material in the molding process can be continuously monitored, which greatly improves the molding quality.

[0137] The matching sleeve 230 fits the bottom of the substrate 2200 , and the matching sleeve 230 can slide along the bottom of the substrate 2200 .

[0138] In this embodiment, multiple placement areas 2220 are evenly spaced along the length of the substrate 2200. Each placement area 2220 is provided with a clearance notch 2230, and the clearance notches 2230 of two adjacent placement areas 2220 are spaced apart. When the second mating rod 220 reaches a point far from the target area, the mating sleeve 230 is positioned between the clearance notches 2230 of the two adjacent placement areas 2220. This allows the air supply assembly to reduce airflow loss between the mating sleeve 230 and the substrate 2200 when cleaning the end surface of the second mating rod 220 and the pressure sensor, thereby improving the cleaning effect on the end surface of the second mating rod 220 and the pressure sensor.

[0139] Furthermore, the size of placement area 2220 matches the size of the bottom of mold 2300. Hemispherical bumps 2240 are provided along the edge of placement area 2220. Multiple bumps 2240 are evenly spaced along the edge of placement area 2220. When mold 2300 is placed on placement area 2220, the bottom of mold 2300 fits in contact with the surface of placement area 2220, and all bumps 2240 fit in contact with mold 2300.

[0140] With this design, even if the pressure sensor slightly lifts the mold 2300 upward, the protrusion 2240 can prevent the mold 2300 from being displaced. When the pressure sensor is separated from the mold 2300, the protrusion 2240 can also ensure that the mold 2300 returns to its original position smoothly.

[0141] Please combine Figure 12 This embodiment also provides a high-level radioactive liquid waste glass sample preparation system 3000, which includes: a melting mechanism 3100, a discharging mechanism 3200 and the above-mentioned linear forming device 2000.

[0142] The melting mechanism 3100 is used to heat the nuclear waste glass to a molten state, and the discharging mechanism 3200 is used to put the nuclear waste glass in a molten state in the melting mechanism 3100 into the mold 2300 of the linear forming device 2000.

[0143] The driving shaft 100 is used to drive the substrate 2200 to move, so that the molds 2300 are sequentially transported to the discharge mechanism 3200, so that the molds 2300 sequentially receive the nuclear waste glass in a molten state.

[0144] The high-level radioactive liquid waste glass sampling system 3000 provided in this embodiment can, during the process of sampling nuclear waste glass, realize the transportation of the mold 2300 and also be used to detect whether there is any material residue in the mold 2300, or whether the weight of the material in the mold 2300 filled with material meets the standard. While the molding process is in progress, the weight of the material in the molding process can be continuously monitored, thereby greatly improving the molding quality.

[0145] It is understood that the melting mechanism 3100 is provided with a matching heating component, a temperature measuring component, and a control component for controlling the heating component and the temperature measuring component, which will not be described in detail in this application.

The inner cavity of the melting mechanism 3100 can be set to be wide at the top and narrow at the bottom. The discharge mechanism 3200 is set at the bottom of the melting mechanism 3100 so that the discharge mechanism 3200 can fully discharge the molten glass in the melting mechanism 3100.

[0148] A heat insulating layer is provided on the outside of the melting mechanism 3100. The heat insulating layer may be made of porous alumina, mullite or high temperature resistant silicon aluminum filler, but is not limited thereto.

[0150] S1. The nuclear waste glass is placed into the melting mechanism 3100.

The preset heating rate, temperature, and time can be flexibly set according to actual needs.

[0151] S2. Use the discharge mechanism 3200 to put the glass in the melting mechanism 3100 into the mold 2300, and use the linear forming device 2000 to transport the molds 2300 one by one to the discharge mechanism 3200, and use the discharge mechanism 3200 to put the glass in the melting mechanism 3100 into each mold 2300.

[0152] S3. After the sample is sufficiently cooled, the small sample is taken out from the mold 2300.

[0153] Among them, you can flexibly choose whether to anneal the glass according to actual needs.

[0154] When annealing is selected, a heating mechanism for annealing can be provided on the surface of the substrate 2200 to directly heat the mold 2300 , thereby heating the glass inside the mold 2300 , thereby completing the heating operation of the annealing process.
