Detailed implementation manners

[0023] The following further elaborates on the present disclosure in conjunction with the accompanying drawings and implementation manners. It can be understood that the specific implementation manners described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the convenience of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0024] It should be noted that, without conflict, the implementation manners in the present disclosure and the features in the implementation manners can be combined with each other. The following will elaborate on the present disclosure in detail with reference to the accompanying drawings and implementation manners.

[0025] As Figure 1 、 2 and shown in FIG. 3, according to the first implementation manner of the present disclosure, a slicing device is provided, including: a straightening device, a feeding device, and a cutting device for slicing a material tape; the straightening device is used to straighten the material tape; the feeding device is arranged between the straightening device and the cutting device, and the feeding device is used to clamp the material tape and convey the material tape to the cutting device; the feeding device reciprocates between the straightening device and the cutting device through a ball screw; at least one material channel is provided at corresponding positions of the straightening device, the feeding device, and the cutting device.

[0026] In one implementation manner, there can be multiple material channels, so that multiple material tapes can be cut simultaneously, greatly improving the production efficiency. In this implementation manner, as Figures 1 to 5 shown, four material channels are provided, that is, four material tapes are operated simultaneously.

[0027] As Figure 4 shown, the straightening device may include a guide roller and at least one pair of straightening rollers; the axis of the guide roller is perpendicular to the axis of the straightening rollers. In this implementation manner, as Figure 4As shown in the figure, the guiding rollers are arranged along the direction of the distribution of the vertical straightening device, the feeding device and the cutting device; the channel for the strip to pass through is between any two adjacent guiding rollers, that is, the strip channel; the edge of the strip is tangent to two adjacent guiding rollers, so as to guide the strip and prevent the strip from skewing.

[0028] As Figure 4 shown in the figure, in this embodiment, there are three pairs of straightening rollers; the three pairs of straightening rollers are arranged along the direction of the distribution of the straightening device, the feeding device and the cutting device; the channel for the strip to pass through is between each pair of straightening rollers, that is, the strip channel; the minimum distance between the outer circumferential surfaces of each pair of straightening rollers matches the thickness of the strip. Preferably, at least one pair of the outer circumferential surfaces of the straightening rollers is provided with a groove adapted to the width of the strip, which is the second straightening roller 14; the straightening roller without the groove is the first straightening roller 13.

[0029] As Figure 4 shown in the figure, it may further include: a detection device, which is arranged on the straightening device 10, corresponding to the corresponding strip channel, and is used to detect the strip in the strip channel. In this embodiment, the detection device is an opposed fiber optic sensor 15.

[0030] In one embodiment, it may further include a driver, which drives the feeding device 11 to reciprocate along the distribution direction of the straightening device 10, the feeding device 11 and the cutting device 2.

[0031] The driver may be one of a servo motor 17 and a stepper motor. The driver drives the ball screw 18 to rotate, thereby driving the feeding device 11 to reciprocate and realizing the feeding of the strip. As Figure 4 shown in the figure, in this embodiment, the driver is a servo motor 17.

[0032] As Figure 4 shown in the figure, the feeding device 11 may further include a guiding plate 19; the guiding plate 19 is used to guide the strip. A long groove may be formed on the guiding plate 19 along the distribution direction of the straightening device 10, the feeding device 11 and the cutting device 2, and the width of the long groove matches the width of the strip, so as to guide the strip.

[0033] As Figure 4As shown in the figure, an elastic pressing block 25 is arranged above the guiding plate 19. The elastic pressing block 25 moves up and down through a material pressing cylinder 16, so as to press or loosen the material tape. The feeding process is as follows: the material pressing cylinder 16 pushes the elastic pressing block 25 to move downward to press the material tape, and then the servo motor 17 drives the ball screw 18 to rotate, so as to drive the guiding plate 19, the material tape, the elastic pressing block 25 and the material pressing cylinder 16 to move forward, and feed the material tape into the cutting device 2; when the cutting device 2 cuts the material tape, the material pressing cylinder 16 pulls the elastic pressing block 25 to move upward to loosen the material tape, and then the servo motor 17 drives the ball screw 18 to reverse, so as to drive the guiding plate 19, the material tape, the elastic pressing block 25 and the material pressing cylinder 16 to move backward to prepare for the next feeding. The elastic pressing block 25 can adopt a polyurethane pressing block 31, a rubber pressing block 31, etc., so as to ensure that each material tape can be pressed tightly when there are multiple material channels.

[0034] In one embodiment, the reciprocating distance of the feeding device 11 is controlled by a controller, and the controller is one of a PLC and a single-chip microcomputer. The controller is electrically connected to the driver, and by setting the feed pulse amount of the servo motor 17 or the step angle of the stepping motor through the controller, the feeding pitch of the feeding device 11 can be changed. The controller can be a human-machine interface with PLC function, so that the operator only needs to set the feeding pitch through the human-machine interface, and the operation difficulty is extremely low.

[0035] As Figure 1 and 2 shown in the figure, the present disclosure may further include: an unwinding device; the unwinding device is used for unwinding a material roll 4 into a material tape; the unwinding device includes at least one rotating shaft and a rotating driving device 5 for driving the rotating shaft to rotate; a fixing device is arranged on the rotating shaft; the material roll 4 is fixed to the rotating shaft through the fixing device.

[0036] As Figure 2 shown in the figure, the number of the rotating shaft and the rotating driving device 5 corresponds to the number of material channels. In this embodiment, both the rotating shaft and the rotating driving device 5 are provided with four. The fixing device can be a locking sleeve sleeved outside the rotating shaft; the material roll 4 is sleeved outside the rotating shaft, and then the locking sleeve is sleeved on, so that the material roll 4 can be fixed on the rotating shaft.

[0037] As Figure 2 shown in the figure, the unwinding device may further include a first conductive rod 3 and a second conductive rod 7; the unwound material roll 4 passes through the first conductive rod 3 and the second conductive rod 7 in sequence. Whether the material roll 4 is unwound is judged according to whether the first conductive rod 3 and the second conductive rod 7 are conducted, that is, when the material tape contacts both the first conductive rod 3 and the second conductive rod 7 at the same time, it is proved that the material tape is tightened and needs to be unwound, then the rotating driving device 5 rotates the rotating shaft and the material roll 4 on the rotating shaft to unwind the material roll 4.

[0038] The rotating driving device 5 can be a reduction motor; the reduction motor can be electrically connected to a speed regulator 6, so as to adjust the unwinding speed of the material roll 4.

[0039] The cutting device 2 may include a cutting die 9 and a cutting driving device 8. Specifically, the cutting die 9 may include a first cutter 23 and a second cutter 24, and the cutting driving device 8 is used to drive the first cutter 23 and the second cutter 24 to open and close; a through groove penetrating along the distribution direction of the straightening device 10, the feeding device 11 and the cutting device 2 is formed in the first cutter 23, the through groove has a first side wall and a second side wall arranged oppositely, the first side wall is used to support the strip, and the edge of the second side wall is used to cooperate with the second cutter 24 to cut off the strip.

[0040] As [[ID=~4]] Figure 6 shown, along the distribution direction of the straightening device 10, the feeding device 11 and the cutting device 2, the first side wall gradually slopes downward to facilitate the smooth dropping of the cut product; the second side wall gradually slopes upward to form a sharper cutting edge.

[0041] The cutting driving device 8 may include: a first elastic element 26 and a linear driver 20; the first elastic element 26 is used to drive the first cutter 23 and the second cutter 24 to open and form a first gap; the first gap is greater than or equal to the thickness of the unrolled strip 4; the linear driver 20 is used to drive the first cutter 23 and the second cutter 24 to close and cut off the strip. Thus, the linear driver 20 may not be connected to the first cutter 23 and / or the second cutter 24, which is more convenient for replacing different cutting dies 9.

[0042] The cutting die 9 may further include: a pressure block 27 and a second elastic element 28; the pressure block 27 is arranged opposite to the second cutter 24; the second elastic element 28 is used to drive the pressure block 27 and the second cutter 24 to open and form a second gap; the second gap is greater than or equal to the thickness of the unrolled strip 4; the linear driver 20 is used to drive the pressure block 27 to move towards the second cutter 24 and press the unrolled strip 4. By first pressing the strip with the pressure block 27 and then using the cooperation of the first cutter 23 and the second cutter 24 to cut off the strip, it is avoided that the strip moves along during cutting; on the other hand, when the feeding device 11 retracts, the strip will not be taken back. By setting the second elastic element 28 to separate the pressure block 27 and the second cutter 24, the pressure block 27 does not need to be connected to the output end of the linear driver 20, which is more convenient for replacing different cutting dies 9.

[0043] The cutting die 9 may further include: a first template 29 and a limiting plate 30; a cavity is formed in the first template 29; the limiting plate 30 and the second cutter 24 are respectively located on both sides of the first template 29 and are both fixedly connected to the first template 29; the pressure block 27 and the first cutter 23 are both located in the cavity and are arranged to slide up and down; one ends of the pressure block 27 and the first cutter 23 away from the second cutter 24 both abut against the limiting plate 30.

[0044] The cutting die 9 may further include: a pressure block 31, a compression spring 32, a piston 33 and a first pressure rod 34; the pressure block 31 is slidably disposed on the first template 29 along a direction perpendicular to the first direction, the pressure block 31 is located on a side of the limiting plate 30 away from the first template 29, and the pressure block 31 has a spring cavity; the piston 33 is slidably disposed in the spring cavity; the compression spring 32 is located in the spring cavity, and two ends of the compression spring 32 respectively abut against the piston 33 and a wall of the spring cavity; one end of the first pressure rod 34 is connected to the piston 33, and the other end extends to the blank holding block 27; an output end of the linear driver 20 is located at an end of the pressure block 31 away from the blank holding block 27 and is not connected.

[0046] The linear driver 20 may include a servo motor 17, a coupling 21 and a lead screw 22; the servo motor 17 is connected to one end of the lead screw 22 through the coupling 21; a pressure head that slides up and down is in threaded engagement with the lead screw 22; when the servo motor 17 rotates, the lead screw 22 drives the pressure head to move up and down, so as to drive the first cutting blade 23 and the second cutting blade 24 to close or open.
