Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0029] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 shown,

[0030] An electric energy meter batch destruction device includes a main frame 1, a roller conveying line provided on the main frame 1 and used for conveying the turnover box 7, and a destruction frame 2 relatively fixed to the main frame 1;

[0031] At least one aligning device 3 is provided on the side of the roller conveying line. The aligning device 3 includes an aligning strip 301 and an aligning cylinder 302 for driving the aligning strip 301 to move. The moving direction of the aligning strip 301 is horizontal and perpendicular to the conveying direction of the roller conveying line;

[0032] The destruction frame 2 is provided with a mounting plate 201, a punching plate 202 that can move up and down relative to the mounting plate 201, and a plurality of destruction cylinders 203 mounted on the mounting plate 201. The bottom of the punching plate 202 is provided with a plurality of punching needles 204 corresponding to the electric energy meters in the turnover box 7 one by one. The punching plate 202 is provided with a plurality of guide rods 205 slidably connected to the mounting plate 201.

[0033] At least one aligning device 3 is located in front of the destruction rack 2. That is, the turnover box 7 (containing multiple waste electric energy meters) first passes through the aligning device 3 and then reaches the destruction rack 2. It is recorded above that "the guide rod 205 is slidably connected to the mounting plate 201". In addition to using the guide rod 205 for this matching structure, various conventional sliding matching structures such as linear bearings can also be used, as long as they play a guiding and stabilizing role.

[0034] The turnover box 7 containing multiple waste electric energy meters is conveyed by a roller conveyor line and first passes through an aligning device 3. The aligning cylinder 302 of the aligning device 3 drives the aligning strip 301 to move horizontally. The moving direction of the aligning strip 301 is perpendicular to the conveying direction of the roller conveyor line, so as to contact and push the turnover box 7, making the side of the turnover box 7 away from the aligning strip 301 contact the side frame of the roller conveyor line (the side frame belongs to the prior art of the roller conveyor line and is itself a side plate or a similar structure on the side), so as to adjust the turnover box 7 and each waste electric energy meter therein in place. Then, the aligning cylinder 302 drives the aligning strip 301 to reset. The roller conveyor line continues to convey the turnover box 7. When the turnover box 7 reaches the destruction rack 2, there are two options at this time. One is to use a blocking device (such as a movable baffle, a commonly used blocking device in the prior art) to block the turnover box 7, so that the turnover box 7 cannot continue to move forward temporarily (in this case, the roller conveyor line can continue to work without stopping), and the other is to pause the roller conveyor line and continue to convey the turnover box 7 after the destruction is completed.

[0035] Each destruction cylinder 203 works simultaneously, driving the breaking plate 202 and each breaking needle 204 to move downward quickly together. As a result, a part of the breaking needle 204 will directly insert into the waste electric energy meter, and the breaking needle 204 can break the position to be destroyed of the corresponding electric energy meter. The present invention directly breaks through multiple electric energy meters at one time, and instead of using a traditional drill bit, it uses a cylinder to quickly drive the breaking plate 202 and each breaking needle 204 to work, with good breaking effect and high overall efficiency.

[0036] It also includes a main controller and a post-destruction rack 4 fixedly relative to the main frame 1. A number of post-destruction image photographing devices 401 are provided on the post-destruction rack 4. The post-destruction image photographing devices 401 are electrically connected to the main controller, and the post-destruction image photographing devices 401 are cameras.

[0037] The main controller can be various conventional controllers such as a single-chip microcomputer or a NUC host that can perform image processing. The post-destruction image photographing device 401 takes pictures of the waste electric energy meters after destruction. After the image information is transmitted back to the main controller, it can be judged and confirmed whether the waste electric energy meters loaded are completely destroyed.

[0038] It further includes a pre-destruction frame 5 fixedly opposite to the main frame 1. A number of pre-destruction image photographing devices 501 are provided on the pre-destruction frame 5. The pre-destruction image photographing devices 501 are electrically connected to the main controller. The pre-destruction image photographing devices 501 are cameras. The pre-destruction frame 5, the destruction frame 2, and the post-destruction frame 4 are arranged in sequence along the conveying direction of the roller conveyor line.

[0039] The pre-destruction image photographing devices 501 can photograph the waste electric energy meters before destruction. After the image information is transmitted back to the main controller, the initial image information of the waste electric energy meters fed into the machine can be provided to assist the subsequent confirmation work (for example, it can provide a comparison image, so as to finally confirm more accurately whether the waste electric energy meters fed into the machine have been destroyed).

[0040] At least one aligning device 3 is located in front of the pre-destruction frame 5, that is, the turnover box 7 (containing multiple waste electric energy meters) first passes through the aligning device 3 and then reaches the pre-destruction frame 5.

[0041] The punching needle 204 includes a needle base 204.1, a needle body 204.2, and a needle tip 204.3. The needle base 204.1 is connected to the punching plate 202. The needle body 204.2 is cylindrical and arranged vertically. In one punching needle 204: the needle tip 204.3 is connected to the bottom of the needle body 204.2.

[0042] The needle tip 204.3 can pierce (break through) the outer shell of the electric energy meter and the structures (such as chips) inside that need to be destroyed. The needle base 204.1 is used to install and connect the needle body 204.2 and the punching plate 202.

[0043] A plurality of screw holes 202a are provided at the bottom of the punching plate 202. At least one through hole is provided on the needle base 204.1. The through hole includes a large-diameter hole 204.1a and a small-diameter hole arranged coaxially. In one through hole: a screw 202.1 passes through the small-diameter hole and is threadedly connected to one of the screw holes 202a. The head of the screw 202.1 is located inside the large-diameter hole 204.1a, and the head of the screw 202.1 presses the needle base 204.1 tightly against the punching plate 202.

[0044] When different types of electric energy meters need to be destroyed, different screw holes 202a can be selected to cooperate with the screw 202.1, so as to change the position of the needle base 204.1 (the needle tip), as long as "when the punching plate 202 descends, the needle tip is located above the position of the electric energy meter to be destroyed".

[0045] When different types of electric energy meters need to be destroyed, the corresponding punching plate 202 can also be replaced for adaptation.

[0046] The needle seat 204.1 is provided with a pressure spring 206, and the pressure spring 206 is sleeved on the needle body 204.2. The needle body 204.2 is sleeved with a pressure sleeve 207 that can move up and down along the needle body 204.2. In a piercing needle 204: the bottom of the needle seat 204.1 is connected to the upper end of the pressure spring 206, and the lower end of the pressure spring 206 is connected to the upper end of the pressure sleeve 207. The upper end of the pressure sleeve 207, the needle head and the lower end of the pressure sleeve 207 are arranged in sequence from top to bottom.

[0047] After the piercing needle 204 penetrates (breaks) the position to be destroyed of the waste electric energy meter, the piercing needle 204 and the shell of the waste electric energy meter are likely to get stuck with each other. At this time, if the piercing needle 204 rises and resets (driven by the destruction cylinder 203 and the piercing plate 202), it may move up with the waste electric energy meter, and even cause the waste electric energy meter to be separated from the original position in the turnover box 7, thereby affecting subsequent operations. In view of this, a structure such as a pressure piece sleeve 207 is provided in this scheme. When the piercing needle 204 moves downward, the pressure piece sleeve 207 first contacts the surface of the electric energy meter, and then the pressure piece spring 206 is compressed, and then the piercing needle 204 completely extends out of the lower end of the pressure piece sleeve 207 and breaks through the position to be destroyed of the waste electric energy meter (when the piercing needle 204 is destroyed, the pressure piece spring 206 continues to be compressed). After the breakout is completed, the breakout plate 202 resets with the breakout needle 204. In the initial stage of reset, the pressure piece spring 206 continues to press the waste electric energy meter downward through the pressure piece sleeve 207, so that when the breakout needle 204 moves upward, the electric energy meter cannot move upward, that is, the breakout needle 204 will not move upward with the waste electric energy meter, which ensures that the breakout needle 204 can be reset smoothly without affecting the waste electric energy meter. When the breakout needle 204 completely leaves the waste electric energy meter, the breakout plate 202 continues to move upward to reset, and at a certain moment, the pressure piece sleeve 207 will also leave the surface of the waste electric energy meter until it is finally completely reset.

[0048] The pressure piece sleeve 207 is slidably matched with the needle body 204.2, and also includes an inflatable elastic ring 208 arranged coaxially with the pressure piece sleeve 207. The top of the inflatable elastic ring 208 is fixed to the bottom of the pressure piece sleeve 207. The inflatable elastic ring 208 is coaxially arranged with the needle body 204.2, and the inner diameter of the inflatable elastic ring 208 is consistent with the inner diameter of the needle body 204.2.

[0049] As mentioned above, "when the downward moving punching needle 204 breaks through, the pressing sleeve 207 first contacts the surface of the electricity meter, then the pressing spring 206 is compressed, and then the punching needle 204 completely extends out of the lower end of the pressing sleeve 207 and breaks through the position to be damaged on the old electricity meter." As is well known, many places on the surface of the electricity meter are not pure flat surfaces. By using the inflatable elastic ring 208 to contact the surface of the electricity meter, on the one hand, it can reduce the direct impact between the pressing sleeve 207 and the old electricity meter, and on the other hand, it can better fit and press the surface of the electricity meter, thus making the subsequent destruction process more stable. In addition, any form of "drilling" will inevitably generate debris (fragments). In the present invention, after the drilling (breaking through) is completed, when the punching needle 204 leaves the electricity meter, it is very likely that some plastic debris (fragments) and metal debris (fragments) will be carried outwards, and thus these debris (fragments) will enter the surrounding environment (especially some fragments are easily sleeved and stuck on the needle body 204.2).

[0050] In this solution, the inflatable elastic ring 208 with elastic deformation ability is directly used. When the tip 204.3 and the needle body 204.2 move downward and pass through the central hole of the inflatable elastic ring 208, only the inner edge of the inflatable elastic ring 208 will be squeezed by the side of the tip 204.3 and the side of the needle body 204.2, and no additional influence will be generated. When the "drilling" (breaking through) is completed and the punching needle 204 moves upward to reset, the part of the tip 204.3 and the needle body 204.2 passing through the inflatable elastic ring 208 will also squeeze the inner edge of the inflatable elastic ring 208. Therefore, most or all of the debris carried upward by the tip 204.3 and the needle body 204.2 will be scraped off by the inflatable elastic ring 208 and retained inside the old electricity meter. In this way, the negative impact on the surrounding environment can be greatly reduced.

[0051] Supplement: Usually (when the inflatable elastic ring 208 does not contact the surface of the electricity meter), according to the previous description, "the inflatable elastic ring 208 is coaxially arranged with the needle body 204.2, and the inner diameter of the inflatable elastic ring 208 is the same as the inner diameter of the needle body 204.2". When the inflatable elastic ring 208 contacts and presses the surface of the old electricity meter, the inflatable elastic ring 208 will deform and "become thicker" due to being squeezed, and the central hole of the inflatable elastic ring 208 will become significantly smaller. Therefore, at this time, the inner diameter of the inflatable elastic ring 208 will be significantly smaller than the inner diameter of the needle body 204.2. At this time, if the tip 204.3 and the needle body 204.2 pass through the central hole of the inflatable elastic ring 208, the inflatable elastic ring 208 can scrape (friction) the side walls of the tip 204.3 and the needle body 204.2.

[0052] The drum conveyor line includes a front-section drum conveyor partial line 601, a middle-section drum conveyor partial line, and a rear-section drum conveyor partial line 602. The middle-section drum conveyor partial line is located below the punching plate 202. The middle-section drum conveyor partial line includes a middle-section drum frame 603.1 and a plurality of middle-section conveyor drums 603.2 arranged in sequence along the conveying direction of the drum conveyor line. The space between any two middle-section conveyor drums 603.2 is an intermediate interval 603.2a. A number of support seats 604 that can pass through the intermediate interval 603.2a are provided below the middle-section drum conveyor partial line. Each support seat 604 is arranged in sequence along the conveying direction of the drum conveyor line. It further includes at least one support cylinder 605 for driving the lifting of each support seat 604.

[0053] The middle-section drum conveyor partial line further includes a motor for driving one of the middle-section conveyor drums 603.2. Any two adjacent middle-section conveyor drums 603.2 are driven by a belt.

[0054] The cylinder rod of the support cylinder 605 is relatively fixed to the punching frame 2. It further includes a lifting plate 606. The support seat 604 is connected to the lifting plate 606 through a support rod 604.1. The cylinder body of the support cylinder 605 is relatively fixed to the lifting plate 606. The highest point of the cylinder body of the support cylinder 605, the highest point of the cylinder rod of the support cylinder 605, and the lowest point of the cylinder body of the support cylinder 605 are arranged in sequence from top to bottom.

[0055] "The highest point of the cylinder body of the support cylinder 605, the highest point of the cylinder rod of the support cylinder 605, and the lowest point of the cylinder body of the support cylinder 605 are arranged in sequence from top to bottom", that is, the support cylinder 605 is inverted.

[0056] When the punching plate 202 drives the punching needle 204 to work, the impact on the waste electricity meter, the turnover box 7, and the drum conveyor line (middle-section drum conveyor partial line) below the turnover box 7 is relatively large, and it is easy to cause damage to the middle-section drum conveyor partial line. In this solution, before the punching process starts, the support cylinder 605 works to drive each support rod 604.1 and each support seat 604 to rise until the top of the support seat 604 reaches a position higher than the middle-section conveyor drum 603.2. In this way, the turnover box 7 will be supported by each support seat 604. During the punching process, the middle-section drum conveyor partial line will not be impacted, and its service life can be guaranteed. After the punching is completed, the support cylinder 605 works to drive structures such as each support rod 604.1 and each support seat 604 to descend and reset, and the turnover box 7 falls back onto the middle-section drum conveyor line again (the top of the support seat 604 also resets to a position lower than the middle-section conveyor drum 603.2).

[0057] The above has introduced the embodiments of the present invention in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
