[0035] It should be noted that, for the convenience of description and to enable those skilled in the art to quickly understand the technical solution of the present invention, the following text only describes the technical features that are strongly related (directly or indirectly related) to the technical problem and / or technical concept to be solved by the present invention, and will not describe the technical features that are weakly related to the technical problem and / or technical concept to be solved by the invention. Since the technical features with a weaker degree of correlation belong to the common knowledge in the field, even if the present invention does not describe the features with a weaker degree of correlation, it will not lead to insufficient disclosure of the present invention.

[0036] The present invention provides a control method for a shredder 100 to solve the problem that the existing shredder 100 determines the installation position of the blade 4 by setting a mechanical positioning block, requires a lot of manual adjustment of the blade 4 feed, has a large workload, and the accuracy of the installation position cannot be guaranteed.

[0037] like Figure 1 and Figure 2 As shown, the shredder 100 includes a first driving mechanism 5, a transmission assembly 6, a second driving mechanism, a knife roller body 2 and a knife roller body frame 1. The first driving mechanism 5 is used to drive the transmission assembly 6, and the transmission assembly 6 can drive the blade 4 to be in an extended state. The second driving mechanism is used to drive the knife roller body 2 to rotate. N knife installation positions are provided on the knife roller body 2, and each knife installation position corresponds to a blade 4. The knife roller body 2 is installed on the knife roller body frame 1.

[0038] The first drive mechanism 5 and the second drive mechanism are both configured as motors, that is, the output shaft of the first drive mechanism 5 is connected to the transmission assembly 6 , and the output shaft of the second drive mechanism is connected to one end of the cutter roller body 2 .

[0039] It should be noted that the shredder 100 of the present invention requires manual placement of the blade 4 on the installation position, and controls the first drive mechanism 5 to drive the transmission assembly 6 so that all blades 4 are in an extended state, and the extended length reaches a preset length. While the first drive mechanism 5 is running, the second drive mechanism is controlled to drive the cutter roller body 2 to rotate. When the extended length of the blade 4 reaches the preset length, the first drive mechanism 5 and the second drive mechanism are controlled to stop running, and the feeding of the blade 4 is completed.

[0040] The rotation direction of the blade roller body 2 can be set to clockwise rotation or counterclockwise rotation, and the present invention is not limited to this, and those skilled in the art can choose according to actual needs.

[0041] like Figure 3 As shown, in some embodiments of the present invention, the control method of the slicing machine 100 includes:

[0042] Step S110, in response to the detection of blades 4 at all N installation positions, the first drive mechanism 5 and the second drive mechanism are controlled to operate simultaneously. The first drive mechanism 5 operates at a certain speed so that the transmission assembly 6 feeds slowly. Specifically, the feed speed of the blade 4 can be set to 0.01m / s. The second drive mechanism operates at a certain speed so that the cutter body 2 rotates slowly. Specifically, the rotation speed of the cutter body 2 can be set to 1r / min.

[0043] The shredder 100 further comprises a camera assembly, which is located on one side of the cutter roller body 2 and is used to detect whether a blade 4 is placed on the cutter installation position on the cutter roller body 2 .

[0044] In order to avoid the installation position of the camera assembly interfering with the normal operation of the wire cutter 100, the camera assembly can be independently set outside the wire cutter 100, and the camera assembly can be set at a position that can obtain the position where the blade 4 is installed on the cutter body 2. In other embodiments of the present invention, the camera assembly includes a camera and a cantilever, one end of the cantilever is fixedly connected to the cutter body frame 1, and the other end of the cantilever is rotatably connected to the camera. The operator can rotate the camera to adjust the shooting angle of the camera lens. Among them, the position of the camera assembly is fixed, and the cutter body 2 is driven to run by controlling the second driving mechanism, so that the camera can obtain pictures of all installation positions, and by comparing the obtained pictures with the preset picture model, it is judged whether the blade 4 is placed in the installed position.

[0045] Wherein, step S110 "in response to detecting blades 4 at N installation positions" includes:

[0046] Step S111, in response to detecting the blade 4 at the first installation position, the second drive mechanism is controlled to operate until the second installation position on the knife roller body 2 rotates to the first position, and the second drive mechanism is controlled to stop operating. The first position is a position where the knife roller body frame 1 can completely expose any one of the N installation positions to the outside. After the operator places the blade 4 on the first installation position, when the camera assembly detects that there is a blade 4 at the first installation position, the second drive mechanism is controlled to operate to drive the knife roller body 2 to rotate, so that the camera assembly detects that the second installation position on the knife roller body 2 rotates to the first position, and then the second drive mechanism is controlled to stop operating, so that the operator can place the blade 4 on the second installation position, and in this way, all blades 4 can be placed on all installation positions.

[0047] Step S112, in response to detecting the blade 4 at the second installation position, controlling the second drive mechanism to operate until the third installation position on the cutter roller body 2 rotates to the first position, and then controlling the second drive mechanism to stop operating;

[0048] ……;

[0049] Step S11N, in response to detecting a blade 4 at the Nth installation position, the N blades 4 are placed.

[0053] Wherein, step S111 further includes:

[0054] Step S1113, if there is no installation position completely exposed outside the knife roller body frame 1, control the second drive mechanism to drive the knife roller body 2 to rotate until there is any installation position completely exposed outside the knife roller body frame 1, that is, execute step S1111.

[0055] Step S120, determining whether the N blades 4 are in a second position, where the second position is a position where the blades 4 extend out by a preset length.

[0056] The shredder 100 includes a detection module 3, which is arranged on the cutter body frame 1, and the detection module 3 is used to detect whether the blade 4 is in the second position. Specifically, an arc groove is arranged on the cutter body frame 1, and the detection module 3 can be movably installed in the arc groove. The operator can adjust the position of the detection module 3 so that the detection module 3 can detect the extended length of the blade 4. Among them, the detection module 3 can be set as a photoelectric sensor. The present invention preferably uses a high-precision photoelectric sensor to detect the extended position of the blade 4, that is, when the extended length of the blade 4 blocks the laser beam emitted by the high-precision sensor, it is judged that the blade 4 is in the second position.

[0057] The preset length can be obtained based on the nameplate of the shredder 100 , the operator's experience, or by testing the extended length of the blade 4 for multiple times.

[0058] Step S130: If yes, the first driving mechanism 5 and the second driving mechanism are controlled to stop running, and the installation of N blades 4 is completed. If no, step S120 is executed.

[0059] In some other embodiments of the present invention, the step of “installation of N blades 4 is completed” in step S130 includes:

[0060] The time when the N blades 4 are installed and the working efficiency of the shredder 100 after starting to work are obtained and recorded.

[0061] After the step of "installation of N blades 4 is completed" in step S130, the following steps are further included:

[0062] Step S140, in response to the blade 4 of the shredder 100 needing to be replaced, a reminder message is generated to remind the user to replace the blade 4. The reminder message is set to be a vibration sound, a buzzer sound, a voice reminder, and a text message reminder.

[0063] In some further embodiments of the present invention, step S140 of "responding to the need to replace the blade 4 of the shredder 100" further includes:

[0064] Step S141, obtaining the accumulated usage time of the blade 4.

[0065] Step S142, determining whether the accumulated usage time of the blade 4 reaches a preset time. The preset time can be obtained according to the nameplate of the shredder 100 or the experience of the operator.

[0066] Step S143: if the accumulated usage time of the blade 4 reaches a preset time, the blade 4 of the shredder 100 needs to be replaced.

[0067] In other embodiments of the present invention, step S140 of "responding to the need to replace the blade 4 of the shredder 100" further includes:

[0068] Step S144, obtaining the working efficiency of the shredder 100 within a preset time period, wherein the preset time period can be set to the working efficiency within three months, two months, one month, two weeks or one week.

[0069] Step S145, determining whether the working efficiency of the shredder 100 reaches a preset efficiency.

[0070] Step S146: If the working efficiency of the shredder 100 does not reach the preset efficiency, the shredder 100 needs to replace the blade 4. If not, execute step S144.
