Description

Technical Field

[0001] The invention relates to the technical field of activated carbon tube cutting, in particular to a portable activated carbon tube cutting tool. Background Art

[0002] In the process of life and production, it is necessary to conduct certain tests on the environment. When testing the air condition, sampling activated carbon tubes are usually used to sample organic compounds in the environment, and then the sampling activated carbon tubes are experimentally analyzed; when the activated carbon tubes are in use, the two ends of the activated carbon tubes need to be cut, and then the cut activated carbon tubes are placed in the atmospheric sampler for collection; the traditional cutting method of activated carbon tubes is mostly to use pliers for cutting, which is prone to produce a large amount of broken glass, which is easy to affect the sampling of organic compounds and affect the data of subsequent experimental analysis.

[0003] In view of the above problems, after searching, a Chinese utility model patent with publication number CN219882924U discloses a portable activated carbon tube cutter, which is composed of a cutting component and a shell with a cutting hole. The activated carbon tube is inserted into the cutting hole of the shell. The cutter is held by two fingers of one hand, and pressure is slowly applied to make the cutting blade and two rollers form forces in three directions to stably clamp the activated carbon tube. The other hand rotates the activated carbon tube several times, and a circle of smooth scratches can be formed on the outside of the activated carbon tube. A little force can be applied to break the activated carbon tube at the scratch.

[0004] And the Chinese utility model patent with publication number CN212025194U discloses an activated carbon sampling tube cutting device. Through the setting of the positioning plate, the activated carbon sampling tube is not easy to shake when the staff cuts the activated carbon sampling tube, thereby improving the integrity of the cutting marks of the activated carbon sampling tube and achieving the purpose of improving the convenience of cutting the activated carbon sampling tube.

[0005] The above two tools for cutting activated carbon tubes can only cut one end of the activated carbon tube when cutting the activated carbon tube, and the activated carbon tube needs to be cut at both ends when it is actually used, so that the above cutting tools need to be used at least twice to complete the cutting of the activated carbon tube, and when the other end of the activated carbon tube is cut, the material inside the activated carbon tube is easily driven by the inertia during cutting, resulting in the problem that the activated carbon material is easily thrown out through the cut opening; furthermore, when the above two sets of cutting tools are actually used, the activated carbon tube needs to be rotated and moved by hand, which not only cannot achieve one-handed cutting, but also has poor operation convenience, and the hand's rotating and moving force is difficult to control, which easily affects the cutting effect and causes damage to the activated carbon tube when the hand's moving force is too large.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] Refer to the attached Figures 1 to 11 A portable activated carbon tube cutting tool comprises a movable frame 1, one end of the movable frame 1 is fixedly connected to a U-shaped bracket 2, the inside of the U-shaped bracket 2 is rotatably connected to a clamping assembly 4 for clamping an activated carbon tube body 3, one end of the movable frame 1 is equipped with two positioning cutting assemblies 5 for positioning and cutting the two ends of the activated carbon tube body 3, and the inside of the movable frame 1 is provided with a driving assembly 6 for rotating and driving the clamping assembly 4;

[0045] A handle is fixedly connected to one side of the bottom of the movable frame 1, which is convenient for the staff to control the cutting tool by hand. Through the combination of the movable frame 1 and the handle, the whole is formed into a "gun shape", which is not only convenient for the staff to cut the activated carbon tube body 3 with one hand, but also convenient for subsequent carrying, thereby improving the convenience and practicality of its operation;

[0046] By rotating and installing the clamping assembly 4 for clamping the activated carbon tube body 3 inside the U-shaped bracket 2, not only can the activated carbon tube body 3 to be cut be clamped to ensure the stability of its end when being cut, but the clamped activated carbon tube body 3 can also rotate on its own to facilitate the subsequent annular cutting work;

[0047] The driving assembly 6 is used to drive the activated carbon tube body 3 clamped by the clamping assembly 4 to rotate, and the two ends of the activated carbon tube body 3 are annularly cut through the two positioning and cutting assemblies 5;

[0048] By rotatably installing a clamping assembly 4 for clamping the activated carbon tube body 3 inside the U-shaped bracket 2, not only can the activated carbon tube body 3 to be cut be clamped to ensure its stability when the end is cut, but also through the setting of the driving assembly 6, the clamped activated carbon tube body 3 can be driven to rotate, and with the cooperation of two symmetrically arranged positioning and cutting assemblies 5, the two ends of the activated carbon tube body 3 can be circularly cut at the same time, which has the function of multi-part cutting, thereby improving the practicability of the cutting tool and solving the problem that the existing cutting tools generally only have the cutting function of a single end, and during the cutting process, the hand is required to rotate and move the activated carbon tube, thereby reducing the convenience of the cutting operation.

[0049] Refer to the attached Figure 6 and Figure 7 The clamping assembly 4 includes a casing 41 rotatably connected to the inside of the U-shaped bracket 2, and a clamping member 44 for clamping the activated carbon tube body 3 is arranged inside the casing 41. Gears 42 are fixedly connected to both sides of the casing 41. The bottoms of the two gears 42 are meshed with U-shaped toothed plate frames 43, and the U-shaped toothed plate frames 43 are connected to the driving end of the driving assembly 6;

[0050] By providing a clamping member 44 inside the casing 41, the activated carbon tube body 3 inserted inside the casing 41 can be clamped to ensure its stability during subsequent cutting; the clamping member 44 is a clamping member used for clamping tubular objects in the prior art;

[0051] Two gears 42 are fixedly connected to the casing 41, and a U-shaped toothed plate frame 43 is meshed at the bottom of the two gears 42. The U-shaped toothed plate frame 43 is connected to the driving end of the driving component 6, so that when the U-shaped toothed plate frame 43 is driven in a feeding reciprocating manner by the driving component 6, the movement of the U-shaped toothed plate frame 43 can drive the two gears 42 to perform forward and reverse rotation through meshing, and then drive the casing 41 to perform forward and reverse rotation, and finally drive the built-in clamped activated carbon tube body 3 to rotate forward and reverse. In conjunction with the setting of the two positioning and cutting components 5, the two ends of the two activated carbon tube bodies 3 can be synchronously cut, with the function of rapid cutting.

[0052] See attached Figure 7 The clamping member 44 includes two arc-shaped clamping plates 441 slidably connected to the inside of the casing 41 and a bidirectional screw rod 442 rotatably connected to the inside of the casing 41. The outer surfaces of both ends of the bidirectional screw rod 442 are threadedly connected to transmission frames 443. The two transmission frames 443 are fixedly connected to the two arc-shaped clamping plates 441 respectively.

[0053] By manually rotating the bidirectional screw rod 442, the two transmission frames 443 can be driven to move relative to or away from each other, and the relative or separate movement of the two transmission frames 443 can drive the relative or separate movement of the two arc-shaped clamping plates 441;

[0054] By moving the two arc-shaped clamping plates 441 in relative directions, the activated carbon tube body 3 inserted in the sleeve 41 can be clamped, and the positioning of the axial clamping is ensured, further improving the smoothness of the subsequent cutting;

[0055] Both ends of the two arc-shaped clamping plates 441 are provided with arc-shaped auxiliary plates 444, and the four arc-shaped auxiliary plates 444 are slidably connected to the inside of the arc-shaped clamping plates 441 through a guide rod group, and the inner surfaces of the two arc-shaped clamping plates 441 and the four arc-shaped auxiliary plates 444 are provided with elastic buffer pads;

[0056] By setting two arc-shaped auxiliary plates 444, not only the clamping area of ​​the activated carbon tube body 3 is increased and the clamping stability is improved, but also the clamping range can be adjusted according to actual conditions to further improve the cutting stability. By moving the arc-shaped auxiliary plates 444 to a close cutting distance, the stability of the activated carbon tube body 3 when it is broken can be increased, thereby preventing the activated carbon tube body 3 from being broken as a whole, and further improving the cutting stability of the activated carbon tube body 3.

[0057] See attached Figure 2The driving assembly 6 includes a telescopic rod 61 fixed inside the movable frame 1 and a pressure cylinder 62 storing a liquid medium therein, the pressure cylinder 62 is fixedly connected to the telescopic cylinder in the telescopic rod 61 through a delivery pipe, a telescopic column is sealed and slidably arranged in the telescopic cylinder of the telescopic rod 61, and one end of the telescopic column extends to the outside of the movable frame 1, and one end of the telescopic column is fixedly connected to the U-shaped toothed plate frame 43;

[0058] The liquid medium in the pressure cylinder 62 enters the telescopic cylinder of the telescopic rod 61 through the delivery pipe. The continuous introduction of the liquid medium can squeeze the telescopic column inside the telescopic cylinder, so that the telescopic column is lifted, forming a rotation drive work of the clamping assembly 4. On the contrary, the liquid medium in the telescopic rod 61 is extracted by the pressure cylinder 62, and its negative pressure can drive the telescopic column to contract and drive the clamping assembly 4 to rotate. With the setting of the positioning and cutting assembly 5, the end of the activated carbon tube body 3 can be cut;

[0059] The pressure cylinder 62 is provided with a pressurizing member for pressurizing the built-in liquid medium;

[0060] By setting the pressure piece, the liquid medium inside the pressure cylinder 62 can be pressurized, so that the liquid medium inside the pressure cylinder 62 enters the telescopic cylinder of the telescopic rod 61 through the delivery pipe. By continuously placing the liquid medium, the telescopic column inside the telescopic cylinder can be squeezed, so that the telescopic column is lifted. It should be noted here that the liquid medium includes but is not limited to water sources, and also includes other fluid liquids.

[0061] See attached Figure 2 The pressurizing member includes a piston plate 63 sealingly and slidably connected to the inside of the pressure cylinder 62 and a T-shaped pressing frame 64 slidably connected to the bottom of the movable frame 1. The pressing end of the T-shaped pressing frame 64 extends to the inside of the pressure cylinder 62, and the pressing end of the T-shaped pressing frame 64 is fixedly connected to the piston plate 63. The bottom of the movable frame 1 is fixedly connected with a reset spring 65 for resetting the T-shaped pressing frame 64 after being pressed.

[0062] The T-shaped pressing frame 64 is provided to facilitate the pressing of the piston plate 63 by the index finger or the middle finger of the staff. The pressing of the piston plate 63 presses the liquid medium inside the pressure cylinder 62, so that the liquid medium inside the pressure cylinder 62 enters the interior of the telescopic rod 61 through the delivery pipe, so that the telescopic column of the telescopic rod 61 is lifted, and then the U-shaped toothed plate frame 43 can be driven to move forward.

[0063] Through the elastic force of the reset spring 65 itself, the T-shaped pressing frame 64 that has lost the pressing force can be reset, which can then drive the piston plate 63 to reset, and finally drive the telescopic column of the telescopic rod 61 to contract, forming the reset work of the U-shaped tooth plate frame 43, which has a good transmission function and is convenient for the staff to cut the activated carbon tube body 3 with one hand.

[0064] See attached Figure 4 and Figure 5 The positioning and cutting assembly 5 includes an L-shaped frame 51 fixed to one end of the movable frame 1 through a connecting rod, a sleeve 52 for sleeve-fitting the end of the activated carbon tube body 3 is arranged inside the L-shaped frame 51, an elastic clamping sleeve 53 is installed on the inner surface of the sleeve 52, and a grinding wheel block 54 is fixedly connected to the L-shaped frame 51;

[0065] The grinding wheel block 54 is used to wrap the end of the activated carbon tube body 3 through the setting of the sleeve 52, and the elastic clamping sleeve 53 is used to elastically clamp the end of the activated carbon tube body 3 to ensure the stability of the end of the activated carbon tube body 3 when the grinding wheel block 54 cuts the end of the activated carbon tube body 3. It should be noted here that the connecting rod and the movable frame 1 are installed in a detachable manner.

[0066] See attached Figures 8 to 10 An auxiliary cutting assembly 7 for cutting and taking materials from the middle part of the activated carbon tube body 3 is arranged on the top of the movable frame 1 .

[0067] By setting the auxiliary cutting component 7, the two ends of the activated carbon tube body 3 near the middle or the middle cotton position can be cut to facilitate the extraction of the built-in activated carbon material. It has a good material extraction function and improves the convenience of subsequent experimental research.

[0068] Embodiment 2: Based on embodiment 1, the difference is that;

[0069] See attached Figures 8 to 10 The auxiliary cutting assembly 7 includes a movable frame 71 slidably connected to the inside of the movable frame 1, and the top and bottom of the movable frame 71 both extend to the top of the movable frame 1, and the top of the movable frame 71 is fixedly connected with a grinding wheel strip 72, and the top of the movable frame 1 is provided with two limit members for the activated carbon tube body 3;

[0070] The grinding wheel strip 72 is used to contact the outer surface of the activated carbon tube body 3, and the grinding wheel strip 72 can cut the outer surface of the activated carbon tube body 3 by manually driving the activated carbon tube body 3 to rotate. When the activated carbon tube body 3 is cut to the breaking requirement, the breaking and separation work can be performed by turning the hand, thereby facilitating the removal of the activated carbon in the built-in glass tube.

[0071] The limiting member includes a fixed sleeve 73 rotatably connected to the top of the movable frame 1 through a rotating shaft, and the inner surface of the fixed sleeve 73 is rotatably connected to a rotating sleeve 74, and the top of the fixed sleeve 73 is fixedly connected to a flip block 75;

[0072] The rotating sleeve 74 is rotatably connected to the interior of the fixed sleeve 73, so that the staff can rotate and drive the activated carbon tube body 3 inserted in the fixed sleeve 73, and the outer surface of the activated carbon tube body 3 can be cut by the setting of the grinding wheel strip 72;

[0073] When the outer surface of the activated carbon tube body 3 is cut to the breaking requirement, the activated carbon tube body 3 can be broken at the cutting position by turning and driving the thin multiple pairs of turning blocks 75, thereby facilitating the subsequent extraction of the activated carbon and improving the convenience of subsequent experimental analysis;

[0074] When it is necessary to conduct experimental analysis on the built-in activated carbon raw material, the cutting position of the activated carbon tube body 3 is the position close to the middle of the two ends or the position of the middle cotton;

[0075] A transmission rod 76 is detachably connected to one side of the T-shaped pressing frame 64, and one end of the transmission rod 76 is fixedly connected to the bottom of the movable frame 71;

[0076] The T-shaped pressing frame 64 is connected to the movable frame 71 by a transmission rod 76, so that the pressing movement of the T-shaped pressing frame 64 can drive the movable frame 71 to move in a synchronous direction, and then drive the grinding wheel strip 72 to move. Through the movement of the grinding wheel strip 72, the activated carbon tube body 3 inserted in the two fixed sleeves 73 can be cut, which has a good linkage function;

[0077] The transmission rod 76 is detachably connected to the T-shaped pressing frame 64, which not only facilitates the driving component 6 to rotationally drive the clamping component 4 alone, but also can selectively drive the auxiliary cutting component 7, further improving the functionality of the cutting tool.

[0078] Embodiment 3: Based on embodiment 1, the difference is that;

[0079] Refer to the attached Figure 2 , Figure 4 and Figure 5 , the bottom of the L-shaped frame 51 is rotatably connected to an L-shaped toggle rod 55, and the sleeve 52 is fixed to the top of the L-shaped toggle rod 55;

[0080] The sleeve 52 is fixedly connected to the rotatably mounted L-shaped toggle rod 55, and the sleeve 52 can be driven to rotate by the rotation of the L-shaped toggle rod 55, thereby driving the end of the activated carbon tube body 3 to be folded in half;

[0081] When the end of the activated carbon tube body 3 is cut by the grinding wheel to the required breaking, the end of the activated carbon tube body 3 can be broken by rotating the sleeve 52, thus completing the final cutting of the activated carbon tube body 3.

[0082] Both sides of the U-shaped tooth plate frame 43 are fixedly connected with a toggle block 56 through a connecting frame. The toggle block 56 for feeding motion is used to squeeze the L-shaped toggle rod 55 to drive the sleeve 52 to rotate;

[0083] The toggle block 56 is connected to the U-shaped tooth plate frame 43 by a connecting frame, so that when the U-shaped tooth plate frame 43 is fed, the toggle block 56 can be driven to move synchronously. When the toggle block 56 moves to a certain distance, it can contact the inclined L-shaped toggle rod 55. With the continuous movement of the toggle block 56, the inclined L-shaped toggle rod 55 can be pressed, so that the L-shaped toggle rod 55 rotates, and then the end of the activated carbon tube body 3 can be broken through the sleeve 52 to form the final cutting work;

[0084] The invention has a good automatic cutting and trimming function, and there is no need to break the end of the activated carbon tube body 3 after cutting, which solves the problem that the activated carbon tube cutting tool in the prior art needs to manually break the end of the activated carbon tube separately after cutting, which causes cumbersome operation.

[0085] The inside of the movable frame 1 is slidably connected with an adjustment frame 66 in an up-and-down sliding manner, both ends of the adjustment frame 66 extend to the outside of the movable frame 1, and the bottom of the adjustment frame 66 is fixedly connected with a limit block 67 for limiting the T-shaped pressing frame 64;

[0086] The setting of the adjustment frame 66 makes it convenient for the staff to manually adjust the limit block 67 up and down. When the limit block 67 is retracted upward to the inside of the movable frame 1, the limit on the pressing of the T-shaped pressing frame 64 will be lost. When the T-shaped pressing frame 64 is pressed to the limit position, the telescopic rod 61 in the driving assembly 6 will increase its movement distance, so that the two toggle blocks 56 on the U-shaped toothed plate frame 43 squeeze the two inclined L-shaped toggle rods 55, thereby causing the L-shaped toggle rods 55 to rotate, and finally driving the sleeve 52 to rotate, forming the cutting and breaking work of the activated carbon tube body 3, having the function of self-cutting and breaking, and further improving the convenience of operation;

[0087] On the contrary, the downward movement of the limit block 67 can limit the movement distance of the T-shaped pressing frame 64 to avoid the problem that the pressing distance of the T-shaped pressing frame 64 is too large, resulting in the activated carbon tube body 3 being forcibly broken when the two ends of the activated carbon tube body 3 are cut but have not yet reached the breaking requirement, which can easily cause the activated carbon tube body 3 to be damaged.

[0088] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
