DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0023] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] See also Figure 1 The embodiment of the present application provides a high-precision slitting knife gap detection and adjustment device for slitting pole pieces, and the high-precision slitting knife gap detection and adjustment device includes a knife seat 1, a support roller 3, a cutting roller 2 and a detection component. The support roller 3 is connected to the knife seat 1, and the cutting roller 2 is rotatably connected to the knife seat 1. The cutting roller 2 and the support roller 3 are arranged at intervals along a first direction. The detection component includes a transmitting end 4 and a receiving end 5, and the transmitting end 4 and the receiving end 5 are arranged at intervals along a second direction. The cutting roller 2 is arranged between the transmitting end 4 and the receiving end 5, and the first direction is perpendicular to the second direction.

[0025] The first direction may be the direction indicated by the Z axis in the figure, the second direction may be the direction indicated by the Y axis in the figure, the first direction may be the vertical direction, and the second direction may be the horizontal direction.

[0026] The supporting roller 3 can be fixedly arranged on the knife seat 1 , or can be rotatably arranged on the knife seat 1 .

[0027] The cutting roller 2 cooperates with the supporting roller to cut the pole piece, that is, when the pole piece passes between the cutting roller 2 and the supporting roller 3, the cutting roller 2 can cut the pole piece.

[0028] The detection component is used to detect the distance between the cutting roller 2 and the supporting roller 3. Specifically, the rays emitted by the transmitting end 4 are received by the receiving end 5. By reasonably setting the position of the transmitting end 4, the rays of the transmitting end 4 can be blocked by the cutting roller 2. When the cutting roller 2 is worn to a certain extent, the cutting roller 2 no longer blocks the rays. Therefore, the degree of wear of the cutting roller 2 can be detected in real time through the detection component.

[0029] The detection component includes a transmitter 4 and a receiver 5, and the transmitter 4 and the receiver 5 are arranged at intervals. The advantage of such arrangement is that, on the one hand, the detection component does not occupy the working space of the cutting roller 2, which is convenient for the slitting operation, and on the other hand, the ray can accurately detect the degree of wear of the cutting roller 2. On the other hand, it is convenient to reasonably set the position of the detection component and the cutting roller 2.

[0030] The transmitting end 4 and the receiving end 5 can be selected from suitable products in the prior art. For example, the detection component can be a through-beam photoelectric sensor, whose structure and working principle are well known to those skilled in the art and will not be described here.

[0031] See also Figure 1 In some embodiments, a display component 6 is also included, and the display component 6 is used to display the measurement value of the detection component.

[0032] The display component 6 may be a computer with a display screen, and the transmitting end 4 and the receiving end 5 are electrically connected to the processor of the computer respectively, so that the transmitting end 4 and the receiving end 5 can play a detection role.

[0033] The specific manners of electrically connecting the transmitting end 4 and the receiving end 5 to the processor of the computer are well known to those skilled in the art and will not be described in detail here.

[0034] The display component 6 displays the measured value in real time, so that the operator can know the degree of wear of the cutting roller 2 in time.

[0035] In some embodiments, the display component 6 includes a prompt unit, which is configured to prompt a user when the measured value reaches a threshold value.

[0036] The prompt unit may be a buzzer or a light indicator.

[0037] The prompt unit can remind the operator to replace the cutting roller 2 in time after the cutting roller 2 is worn to a certain extent.

[0038] See also Figure 2 In some embodiments, the detection component further includes an adjusting component, and the transmitting end 4 and the receiving end 5 are respectively connected to the tool holder 1 through the adjusting component.

[0039] The adjusting component is used to adjust the position of the device connected to the adjusting component relative to the tool holder 1 .

[0040] The transmitting end 4 and the receiving end 5 are connected to the knife seat 1 through adjustment components respectively, so that the positions of the transmitting end 4 and the receiving end 5 relative to the knife seat 1 can be adjusted to meet the use requirements.

[0041] See also Figure 2 In some embodiments, the adjusting component includes a fixed seat 7, a movable seat 8 and an elastic member 9. The fixed seat 7 is connected to the knife seat 1, the movable seat 8 is movably arranged on the fixed seat 7 along the first direction, the transmitting end 4 / receiving end 5 is arranged on the movable seat 8, and the elastic member 9 is connected to the fixed seat 7 and the movable seat 8.

[0042] The fixed seat 7 may be provided with a slide rail, and the movable seat 8 is slidably connected to the slide rail. Alternatively, the movable seat 8 / fixed seat 7 is provided with a slide hole, and the fixed seat 7 / movable seat 8 is inserted into the slide hole, so that the fixed seat 7 and the movable seat 8 are slidably connected.

[0043] The purpose of adjusting the position of the transmitting end 4 / receiving end 5 can be achieved by fixing the position of the movable seat 8 relative to the fixed seat 7. The specific fixing structure of the movable seat 8 can be selected from existing structures.

[0044] The elastic member 9 may be a spring, and the elastic member 9 can eliminate the matching clearance between the fixed seat 7 and the movable seat 8 along the first direction, thereby reducing the risk of the movable seat 8 moving during the slitting operation.

[0045] In some embodiments, the elastic member 9 includes two magnetic units, the two magnetic units are spaced apart along the first direction, and the two magnetic units are respectively connected to the fixed seat 7 and the movable seat 8 .

[0046] The relative magnetic poles of the two magnetic units may be the same or different. For example, if the position of the movable seat 8 is fixed by abutting against the side of the movable seat 8 away from the fixed seat 7, the relative magnetic poles of the two magnetic units may be the same, so that the movable seat 8 and the fixed seat 7 have a tendency to move away from each other. If the position of the movable seat 8 is fixed by abutting against the side of the movable seat 8 close to the fixed seat 7, the relative magnetic poles of the two magnetic units may be different, so that the movable seat 8 and the fixed seat 7 have a tendency to move closer to each other.

[0047] The magnetic unit can be a permanent magnet or an electromagnet. The use of the magnetic unit increases the service life of the elastic member 9.

[0048] See also Figure 2In some embodiments, the adjusting component further includes a rotating seat 11 and a control unit. The rotating seat 11 is connected to the tool holder 1, and the rotating seat 11 includes a rotating end whose rotating axis extends along the first direction. The control unit is arranged at the rotating end, and a control ring 13 is arranged on the peripheral wall surface of the control unit, and the end surface of the control ring 13 is wavy, and the movable seat 8 is provided with a contact portion, and the contact portion abuts against the end surface of the control ring 13.

[0049] The rotating seat 11 can be a motor, and the output end of the motor is the rotating end.

[0050] The end surface of the control ring 13 is wavy, so that when the control unit rotates, the movable seat 8 can be displaced along the first direction under the action of the contact portion.

[0051] The contact portion cooperates with the control ring 13 to fix the position of the movable seat 8 relative to the fixed seat 7 on the one hand, and to fine-tune the position of the movable seat 8 by rotating the control unit on the other hand, so that the position of the movable seat 8 is more accurate.

[0052] In some embodiments, the contact portion includes a contact wheel 10 , which is rotatably connected to the movable seat 8 , and a wheel surface of the contact wheel 10 abuts against an end surface of the control ring 13 .

[0053] The rotation axis of the contact wheel 10 may extend along the second direction.

[0054] The wheel surface of the contact wheel 10 abuts against the end surface of the control ring 13, so that there is sliding friction between the contact wheel 10 and the end surface, thereby reducing the wear of the contact part.

[0055] See also Figure 2 In some embodiments, the control unit includes a plurality of control units 12 arranged along a first direction, adjacent control units 12 are detachably connected, the control unit 12 away from the movable seat 8 is connected to the rotating end, and the control ring 13 is selectively arranged on the peripheral wall surface of the control unit 12.

[0056] Adjacent control parts 12 are detachably connected, so that by adjusting the number of control parts 12, the position of the control part 12 provided with the control ring 13 along the first direction can be adjusted, and the position of the movable seat 8 relative to the fixed seat 7 can be adjusted when the movable seat 8 is fixed.

[0057] See also Figure 2 In some embodiments, a threaded hole 15 is provided on one side of the control part 12, and a threaded protrusion 14 is provided on the other side of the control part 12. Between adjacent control parts 12, the threaded protrusion 14 of one control part 12 is threadedly connected to the threaded hole 15 of another control part 12.

[0058] Correspondingly, the rotating end may be provided with a threaded protrusion 14 or a threaded hole 15 so that the control part 12 can be connected to the rotating end.

[0059] The threaded protrusion 14 and the threaded hole 15 cooperate to connect adjacent control parts 12. On the one hand, the control parts 12 can be detachably connected to each other, and the number of control parts 12 can be adjusted as needed. On the other hand, the position of the control part 12 provided with the control ring 13 relative to the rotating end can be adjusted, and thus the position of the movable seat 8 relative to the fixed seat 7 can be adjusted.

[0060] The above embodiments are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made by ordinary technicians in this field to the technical solutions of the present invention should all fall within the protection scope determined by the claims of the present invention.
