[0069] Reference Figure 1-Figure 4 One embodiment of the present invention provides a cutting device for an activated carbon glass sampling tube, comprising:

[0070] A cutting platform 100, wherein the cutting platform 100 is provided with a plurality of placement slots 110;

[0071] Positioning mechanism 200, both ends of the cutting platform 100 are provided with positioning mechanism 200, and the positioning mechanism 200 is linearly slidably connected with the cutting platform 100;

[0072] A rotating mechanism 300, wherein the rotating mechanism 300 is disposed inside the positioning mechanism 200;

[0073] A cutting mechanism 400, wherein the cutting mechanism 400 is disposed inside the positioning mechanism 200;

[0074] The adjusting mechanism 500 is disposed inside the positioning mechanism 200 and is connected to the cutting mechanism 400 to drive the cutting mechanism 400 to adjust the cutting position.

[0075] The control terminal 600, the rotating mechanism 300, the cutting mechanism 400 and the adjusting mechanism 500 are all electrically connected to the control terminal 600, and the start and stop are controlled by the control terminal 600.

[0076] In this embodiment, if Figure 1-Figure 4As shown, the cutting platform 100 is used to place the sampling tube 800 to be cut. The several placement grooves 110 provided on the cutting platform 100 are semicircular, so as to facilitate the placement of the sampling tube 800 to be cut, and also facilitate the rotation of the sampling tube 800 to be cut; positioning mechanisms 200 of the same structure are provided at opposite ends of the cutting platform 100, and the positioning mechanism 200 is used to provide installation positions for the rotating mechanism 300, the cutting mechanism 400 and the adjusting mechanism 500, and also to limit the vertical direction of the sampling tube 800 to be cut, and can collect the cut parts of the sampling tube 800 to be cut. The positioning mechanism 200 is linearly slidably connected with the cutting platform 100, and is used to send the end of the sampling tube 800 to be cut into it for cutting, and can adapt to the cutting of sampling tubes 800 of different lengths, thereby increasing the convenience of use; the rotating mechanism 300 is provided inside the positioning mechanism 200, and is used to drive the sampling tube 800 on the cutting platform 100 to rotate to facilitate the cutting of the cutting mechanism 400, And it is used to clamp the sampling tube 800 to prevent the sampling tube 800 from shaking during the cutting process; the cutting mechanism 400 is arranged inside the positioning mechanism 200, and is used to cut the sampling tube 800 in a rotating state. It should be noted that when cutting the sampling tube 800, the cutting mechanism 400 is in a stationary state, and the tube wall of the rotating sampling tube 800 contacts the cutting mechanism 400 to complete the cutting, thereby reducing the probability of the sampling tube 800 being crushed when being cut; the adjustment mechanism 500 is arranged inside the positioning mechanism 200, and is used to adjust the vertical position of the cutting mechanism 400 to adjust the cutting position. Because different sampling tubes 800 may have different thicknesses and diameters, the cutting mechanism 400 is adjusted by the adjustment mechanism 500 to increase the overall convenience of use; the control terminal 600 adopts an industrial computer and can be set on one side of the cutting platform 100 or at other locations. The control terminal 600 is set to control the start and stop of the rotating mechanism 300, the cutting mechanism 400 and the adjustment mechanism 500.

[0077] One use principle of this embodiment is:

[0078] The sampling tube 800 to be cut is placed in the placement groove 110 of the cutting platform 100, and then the positioning mechanisms 200 at both ends of the cutting platform 100 are pushed so that the two ends of the sampling tube 800 are sent into the interior of the positioning mechanisms 200; the parameters (thickness, diameter, etc.) of the sampling tube 800 to be cut are input into the control terminal 600, so that the control terminal 600 controls the cutting mechanism 400 to move to the corresponding cutting position according to the input parameters; when the cutting mechanism 400 moves to the corresponding cutting position, the control terminal 600 controls the rotation mechanism 300 to drive, and the rotation mechanism 300 clamps the sampling tube 800 and drives the sampling tube 800 to rotate. During the rotation of the sampling tube 800, the cutting mechanism 400 completes the cutting of the sampling tube 800.

[0079] In one embodiment, the positioning mechanism 200 includes a positioning housing 210 and a linear guide rail 220;

[0080] The linear guide rail 220 is disposed on the surface of the positioning housing 210 that contacts the cutting platform 100. The positioning housing 210 is linearly slidably connected to the cutting platform 100 via the linear guide rail 220.

[0081] The positioning housing 210 includes a positioning cavity 211 and a cutting cavity 212, the positioning cavity 211 and the cutting cavity 212 are separated by a baffle 213, and the baffle 213 and the positioning cavity 211 are both provided with through holes having the same number as the placement slots 110;

[0082] The rotating mechanism 300 is disposed in the positioning cavity 211 , and the cutting mechanism 400 is disposed in the cutting cavity 212 .

[0083] In this embodiment, if Figure 2 , Figure 3As shown, the positioning mechanism 200 includes a positioning housing 210 and a linear guide rail 220. The linear guide rail 220 is arranged on the bottom surface of the positioning housing 210. The corresponding cutting platform 100 is provided with a corresponding linear slide groove (not shown in the figure). The positioning housing 210 is linearly slidably connected with the cutting platform 100 through the linear guide rail 220. When cutting the sampling tube 800, the positioning housing 210 can be manually pushed so that the two ends of the sampling tube 800 are sent into the interior of the positioning housing 210. It is also possible to further provide a hydraulic pressure at the bottom of the cutting platform 100. The pushing mechanism (not shown in the figure) pushes the positioning shell 210 through the hydraulic pushing mechanism; the interior of the positioning shell 210 includes a positioning cavity 211 and a cutting cavity 212, and the positioning cavity 211 and the cutting cavity 212 are separated by a baffle 213. The positioning cavity 211 is used to install the rotating mechanism 300, and the cutting cavity 212 is used to install the cutting mechanism 400; the positioning cavity 211 and the baffle 213 are both provided with through holes with the same number as the placement slot 110, and the through holes are used to insert the end of the sampling tube 800, and the size of the through holes can be designed according to the specific situation.

[0084] In one embodiment, the rotating mechanism 300 includes the same number of rotating components 310 as the placement slots 110, and each rotating component 310 is connected to two sets of clamping components 320;

[0085] One end of the rotating assembly 310 is connected to the side of the positioning cavity 211 having a through hole, and the other end is connected to the side of the baffle 213 having a through hole, and the two ends of the rotating assembly 310 are respectively arranged on the same axis as the through hole on the positioning cavity 211 and the through hole on the baffle 213;

[0086] The two groups of clamping assemblies 320 provided for the single rotating assembly 310 are relatively arranged at the upper and lower ends or the left and right ends of the rotating assembly 310. When the rotating assembly 310 rotates, the clamping assemblies 320 at the upper and lower ends or the left and right ends are driven to clamp the sampling tube 800 at the same time.

[0087] In this embodiment, if Figure 1 , Figure 2As shown, the rotating mechanism 300 is composed of a rotating assembly 310 and a clamping assembly 320. The number of the rotating assemblies 310 is the same as the number of the placement slots 110, so as to drive the sampling tube 800 placed on each placement slot 110 to rotate, and each rotating assembly 310 is connected to two groups of clamping assemblies 320. The clamping assemblies 320 are symmetrically arranged at the upper and lower ends, or the left and right ends of the rotating assembly 310. In this embodiment, the clamping assemblies 320 are arranged at the upper and lower ends of the rotating assembly 310. The rotating assembly 310 is arranged in the positioning cavity 211 inside the positioning shell 210, with one end connected to the side of the positioning cavity 211 having a through hole, and the other end connected to the side of the baffle 213 having a through hole. It can be understood that the rotating assembly 310 is erected between the two through holes and is arranged on the same axis as the two through holes; after the sampling tube 800 to be cut is placed and when it is sent into the positioning mechanism 200, the end of the sampling tube 800 first passes through the through hole on the positioning cavity 211, then passes from the rotating assembly 310 to the through hole of the baffle 213, and then enters the cutting cavity 212 from the through hole of the baffle 213. After the end of the sampling tube 800 enters the cutting chamber, the rotating assembly 310 is driven to start and rotate. When the rotating assembly 310 starts to rotate, the rotating assembly 310 will drive the clamping assembly 320 to start as well. The clamping assemblies 320 at the upper and lower ends of the rotating assembly 310 clamp the sampling tube 800, that is, the clamping assembly 320 is driven by the rotation of the rotating assembly 310.

[0088] The role of the rotating assembly 310 is to drive the clamping assembly 320 to clamp the sampling tube 800, so as to ensure that the rotating assembly 310 itself can drive the sampling tube 800 to rotate, and to ensure that the sampling tube 800 will not be damaged by vibration during the rotational cutting process. Because the diameters of the rotating assembly 310, the through hole of the positioning cavity 211 and the through hole of the baffle 213 need to be larger than the diameter of the sampling tube 800 to be cut, in order to ensure that the sampling tube 800 can be normally inserted, when the diameter of the rotating assembly 310 is larger than the diameter of the sampling tube 800, there will be a certain gap between the two (the inner wall of the rotating assembly 310 and the wall of the sampling tube 800), and at this time, it cannot be guaranteed that the rotating assembly 310 can completely and smoothly drive the sampling tube 800 to rotate. At the same time, since the sampling tube 800 and the cutting mechanism 400 are both hard objects, when the tube of the sampling tube 800 When the wall contacts the cutting mechanism 400 for cutting, the gap between the rotating assembly 310 and the sampling tube 800 will cause vibration of the sampling tube 800 during cutting, thereby causing damage to the sampling tube 800 during cutting. Therefore, by setting the clamping assembly 320 at the upper and lower ends of the rotating assembly 310, when the rotating assembly 310 is started to rotate, the clamping assembly 320 is driven to clamp the sampling tube 800, thereby ensuring that the rotating assembly 310 can completely drive the sampling tube 800 to rotate, preventing the sampling tube 800 from vibrating during the rotation and cutting process, thereby avoiding the occurrence of the above-mentioned problem. It should be noted that the rotating assembly 310, the clamping assembly 320, and the sampling tube 800 move almost simultaneously, which can ensure the efficiency of cutting.

[0089] In one embodiment, the positioning housing 210 is provided with a first drive motor 214 and a first transmission shaft 215, the first drive motor 214 is arranged outside the positioning cavity 211, the first transmission shaft 215 is horizontally arranged inside the positioning cavity 211, and the first transmission shaft 215 rotates coaxially with the output end of the first drive motor 214;

[0090] The single rotating assembly 310 includes a rotating shaft 311 and an arc-shaped guide groove 312 arranged on the surface of the rotating shaft 311. The arc-shaped guide groove 312 is wound around the rotating shaft 311 and connected end to end.

[0091] The two ends of the rotating shaft 311 are respectively arranged at the same axis as the through hole on the positioning cavity 211 and the through hole on the baffle 213. The rotating shaft 311 is arranged side by side with the transmission shaft, and the transmission shaft drives the rotating shaft 311 to rotate by belt transmission.

[0092] The two groups of clamping assemblies 320 have the same structure, and both include a guide rod 321, a sliding pressure rod 322, and a pressure plate 323;

[0093] The guide rods 321 of the two groups of the clamping assemblies 320 are respectively arranged at the upper and lower ends or the left and right ends of the rotating shaft 311, and one end of the guide rod 321 is fixedly connected to the side of the positioning cavity 211 having a through hole;

[0094] One end of the sliding pressure rod 322 is slidably sleeved on the guide rod 321, and the other end is arranged toward the rotating shaft 311, and the end extends into the arc-shaped guide groove 312 of the rotating shaft 311;

[0095] The pressing plate 323 is disposed inside the rotating shaft 311 . When the rotating shaft 311 rotates, the arc-shaped guide groove 312 on the rotating shaft 311 drives the sliding pressing rod 322 to slide along the guide rod 321 , and the sliding pressing rod 322 presses the pressing plate 323 to clamp the sampling tube 800 .

[0096] In this embodiment, if Figure 1 , Figure 2 As shown, the positioning housing 210 is provided with a first driving motor 214 and a first transmission shaft 215 . The first driving motor 214 is used to drive the first transmission shaft 215 to rotate, and the driving of the rotating assembly 310 is driven by the first transmission shaft 215 in the form of a belt drive in this embodiment.

[0097] Specifically, the first drive motor 214 is arranged outside the positioning housing 210. According to the arrangement of the structure, the placement slots 110 in this embodiment are four, the through holes on the positioning housing 210 are four, and the rotating assembly 310 is four. The first drive motor 214 / first transmission shaft 215 is located in the middle of the four through holes of the positioning housing 210. Figure 1 As shown; the first transmission shaft 215 is horizontally arranged inside the positioning cavity 211, one end of the first transmission shaft 215 is coaxially connected to the output end of the first drive motor 214, and the other end is provided with teeth. The structures of the four groups of rotating components 310 inside the positioning cavity 211 are all the same, two groups are located on the left side of the first transmission shaft 215, and two groups are located on the right side of the first transmission shaft 215, and the four groups of rotating components 310 are all arranged horizontally side by side with the first transmission shaft 215.

[0098] Specifically, taking a single set of rotating components 310 as an example, the rotating components 310 include a rotating shaft 311 and an arc-shaped guide groove 312. The two ends of the rotating shaft 311 are respectively mounted on the side of the positioning cavity 211 with a through hole and the side of the baffle 213 with a through hole. The outer surface of the rotating shaft 311 close to the baffle 213 is also provided with teeth; one end of the first transmission shaft 215 with teeth and the other end of the rotating shaft 311 with teeth are provided with a belt. When the first transmission shaft 215 rotates, the rotating shaft 311 is driven to rotate by belt transmission.

[0099] For the arc guide groove 312, for example, the rotating shaft 311 is regarded as two semi-cylinders, and the arc guide grooves 312 on the two semi-cylinders are symmetrical. One of the semi-cylinders is used for explanation, and the starting point of the arc guide groove 312 extends from one side of the upper end of the semi-cylinder along the arc surface to one side of the lower end of the semi-cylinder as the end point. The other semi-cylinder is the same. The overall arc guide groove 312 starts from the upper end of one side of the rotating shaft 311 as the starting point, extends along the arc of one half of the arc surface to the lower end of the other side of the rotating shaft 311, and then starts from this end and extends from the arc of the other half of the arc surface back to the starting point, so as to be connected end to end; Figure 2 As shown, except for the upper and lower ends, the rest of the integral arc guide groove 312 runs through the interior of the rotating shaft 311, and the upper and lower ends are used to maintain the integrity of the rotating shaft 311; the arc surface design at the connection between the upper and lower ends is used to enable the clamping assembly 320 to smoothly move periodically along the arc guide groove 312; it should be noted that the rotating shaft 311 is made of metal material to ensure that it is not easy to break during use.

[0100] The clamping assemblies 320 arranged at the upper and lower ends of the rotating shaft 311 have the same structure, and all include a guide rod 321, a sliding pressure rod 322 and a pressure plate 323; one end of the guide rod 321 is fixedly connected to the side of the positioning cavity 211 with a through hole, and the other end is arranged in the direction of the baffle 213; one end of the sliding pressure rod 322 is slidably sleeved on the guide rod 321, and the other end extends into the arc-shaped guide groove 312 of the rotating shaft 311 and contacts the pressure plate 323, which is used to apply pressure to the pressure plate 323, and the end of the sliding pressure rod 322 located in the arc-shaped guide groove 312 (the end in contact with the pressure plate 323) is designed to be semicircular, and the semicircle is made of soft rubber material, so that The sliding pressure rod 322 can still move normally when it encounters the arc connection point of the rotating shaft 311 during movement; the pressure plate 323 is fixed on the inner wall of the rotating shaft 311, and is used to fill the gap between the inner wall of the rotating shaft 311 and the wall of the sampling tube 800, and the pressure plate 323 is similar in shape to the arc guide groove 312. The pressure plate 323 is made of soft rubber material, and the pressure plate 323 has a certain thickness, and the side that touches the sampling tube 800 has anti-slip grooves, so that when the pressure plate 323 presses the wall of the sampling tube 800, the friction between the pressure plate 323 and the wall of the sampling tube 800 is increased, so that it is not easy to slip when the sampling tube 800 is driven to rotate.

[0101] When the first driving motor 214 drives the first transmission shaft 215, the first transmission shaft 215 drives the rotating shaft 311 to rotate through the belt. Since one end of the sliding pressure rod 322 is slidably sleeved on the guide rod 321, and the other end is set in the arc guide groove 312, when the rotating shaft 311 rotates, under the action of the arc guide groove 312, the sliding pressure rods 322 at the upper and lower ends of the rotating shaft 311 make linear reciprocating motion along the guide rod 321, and the movement directions of the sliding pressure rods 322 at the upper and lower ends are opposite; during the movement of the sliding pressure rods 322, the sliding pressure rods 322 at the upper and lower ends of the rotating shaft 311 will always press against the pressure plate 323, so that the other side of the pressure plate 323 is close to the wall of the sampling tube 800, and the purpose of "clamping" the sampling tube 800 is achieved through the sliding pressure rods 322 at the upper and lower ends. After the sampling tube 800 is clamped, the sampling tube 800 will be rotated coaxially with the rotating shaft 311. It should be noted that when the rotating shaft 311 rotates one circle, the sampling tube 800 also rotates one circle. Under the action of the cutting mechanism 400, the sampling tube 800 can be cut. Correspondingly, the sliding pressure rod 322 will also return to the initial position.

[0102] As for the clamping of the sampling tube 800, a spring is usually connected to a plate, and then an elastic force is used to apply an elastic force to the plate so that the plate clamps the sampling tube 800. In this embodiment, if the sampling tube 800 is clamped for cutting by ordinary spring elastic force without applying additional pressure, the sampling tube 800 may shake during the cutting process, which may cause the sampling tube 800 to break, or the sampling tube 800 may not be cut well, thereby reducing efficiency. Because the sampling tube 800 is made of glass and has a certain hardness, and the cutting mechanism 400 also has a certain hardness, when the surface of the rotating sampling tube 800 contacts the cutting mechanism 400 for cutting, a reverse force may be generated when the two contact each other. At this time, if the sampling tube 800 is clamped by spring elastic force, it may vibrate / shake, and the above-mentioned problem may occur. By clamping the sampling tube 800 using the structure and method described in this embodiment, the above-mentioned problems can be avoided, and the structure in this embodiment is simple, low-cost, and effective. When driving the sampling tube 800 to rotate, the clamping assembly 320 always applies pressure to the tube wall of the sampling tube 800, so that the sampling tube 800 can remain stable when cutting.

[0115] The cutting mechanism 400 includes a second driving motor 410, a second transmission shaft 420 and a grinding wheel 440;

[0116] The second drive motor 410 is installed on the end surface of the support platform 530 away from the pushing end of the hydraulic push rod 520, and one end of the second transmission shaft 420 rotates coaxially with the output end of the second drive motor 410;

[0117] The cutting cavity 212 of the positioning housing 210 is provided with an adjustment slot 216, and the other end of the second transmission shaft 420 passes through the adjustment slot 216 and is located in the cutting cavity 212 of the positioning housing 210;

Specifically, the cutting mechanism 400 includes a second drive motor 410, a second transmission shaft 420 and a grinding wheel 440; the second drive motor 410 is installed on the support platform 530, one end of the second transmission shaft 420 is connected to the output end of the second drive motor 410 and rotates coaxially, the cutting chamber 212 of the positioning housing 210 is provided with an adjustment slot 216, the other end of the second transmission shaft 420 passes through the adjustment slot 216 and is located in the cutting chamber 212, the adjustment slot 216 is vertically arranged, and the arrangement of the adjustment slot 216 provides a moving space for the overall cutting mechanism 400 when it is adjusted by the adjustment mechanism 500; one end of the second transmission shaft 420 located in the cutting chamber 212 is connected to the grinding wheel 440. In this embodiment, the cutting end of the sampling tube is scratched by the grinding wheel 440 instead of directly cutting, which avoids the problem of the sampling tube being broken when the cutting blade 430 is used for direct cutting.

[0122] Furthermore, a breaking mechanism 700 is also included, which is installed on the positioning housing 210 and is used to break the sampling tube after being scratched by the grinding wheel 440; specifically, the breaking mechanism 700 includes a heating component 710 and a cooling component 720.

The output ends of the heating component 710 and the cooling component 720 are both connected to the cutting chamber 212. After the cutting mechanism 400 has completed the scratching of the sampling tube, the cutting end of the sampling tube is first heated rapidly to a certain temperature by the heating component 710 (using a burner as an example), and then the cooling component 720 (using a device for conveying cooling water as an example) is started to spray cooling water on the cutting end of the sampling tube, so that the temperature of the sampling tube drops rapidly.

This embodiment uses the temperature difference fracture method, and then cooperates with the grinding wheel 440 to scratch the sampling tube to complete the cutting of the sampling tube. This method can reduce the problem of fragmentation of the sampling tube during the cutting process, and improves work efficiency to a certain extent.

The sealing ring 217 is used to isolate the temperature generated by the heating component 710 and the cooling component 720 to a certain extent to avoid affecting the other end of the sampling tube at the scratch.
