DETAILED DESCRIPTION

[0021] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown, the utility model provides a cable sheath cutting device, including a workbench 1, the top outer wall of the workbench 1 is fixedly connected to a fixed plate 4, the outer wall of the fixed plate 4 is fixedly connected to a motor B5, the outer wall of the fixed plate 4 is provided with a winding mechanism 3, the top outer wall of the workbench 1 is fixedly connected to a base 6, the top outer wall of the base 6 is provided with a cutting mechanism 2, the cutting mechanism 2 includes a motor A201, the output shaft of the motor A201 is fixedly connected to a rotating shaft 202, the outer wall of the rotating shaft 202 is provided with a plurality of groups of card grooves 209, the outer wall of the rotating shaft 202 is slidably connected to a sleeve 203, the outer wall of the sleeve 203 is fixedly connected to a plurality of groups of protrusions 204, the inner wall of the sleeve 203 is elastically connected to a card block 211 through a spring B210, the top outer wall of the base 6 is fixedly connected to a baffle 205, the top outer wall of the base 6 is fixedly connected to a knife seat 206, and the knife seat 206 is elastically connected to a cutting knife 208 through a spring A207.

[0023] The above scheme is adopted: the device can be used by placing the workbench 1 on the ground, and the rolled cable sheath can be placed on the rolling mechanism 3, and the rolling mechanism 3 is driven to rotate by the motor B5 to transport the cable sheath to the base 6, and is cut by the cutting mechanism 2; when the motor A201 is started, the output shaft of the motor A201 drives the rotating shaft 202 to rotate, because the clamping block 211 and the clamping slot 209 remain in a clamping state, and the sleeve 203 can only move laterally on the outer wall of the rotating shaft 202 but cannot rotate, so that the rotating shaft 202 can drive the sleeve 203 to rotate synchronously; there are multiple groups of protrusions 204, Each group is provided with a different number of protrusions 204, and are arranged in an equiangular circle on the outer wall of the sleeve 203. When the sleeve 203 rotates, the protrusions 204 are driven to rotate, and the protrusions 204 squeeze the cutter 208, causing the cutter 208 to move downward. After the cutter 208 moves downward, it automatically moves upward and resets due to the elastic force of the spring A207. By continuously squeezing the cutter 208 through multiple groups of protrusions 204, the cutter 208 can maintain a certain frequency to cut the cable sheath, thereby ensuring the accuracy of the cutting length of the cable sheath, and there is no need for the operator to manually cut the sheath, which is more convenient to operate.

[0024] like Figures 2 to 4 As shown, the motor A201 is fixedly connected to the top outer wall of the base 6, the rotating shaft 202 is rotatably connected to the baffle 205, one end of the spring A207 is fixedly connected to the top outer wall of the knife seat 206, the other end of the spring A207 is fixedly connected to the outer wall of the cutter 208, the cutter 208 is slidably connected to the inner wall of the knife seat 206, one end of the spring B210 is fixedly connected to the inner wall of the sleeve 203, the other end of the spring B210 is fixedly connected to the outer wall of the block 211, the block 211 is slidably connected to the inner wall of the sleeve 203, the block 211 is engaged with the slot 209, and the protrusion 204 is in contact with the top outer wall of the cutter 208.

[0025] The above scheme is adopted: by pulling the block 211 upward, the block 211 is disengaged from the card slot 209, and the spring B210 is forced to shrink, so that the limit of the sleeve 203 can be released, and the sleeve 203 can be moved laterally on the outer wall of the rotating shaft 202, and the length of the sleeve can be cut as needed, and different numbers of protrusions 204 are matched with the position of the cutter 208. After the correspondence, the block 211 can be released, so that the spring B210 drives the block 211 to pop up downward due to the elastic force and engage with the card slot 209, so that the sleeve 203 can be fixed to the rotating shaft 202; when the required length of the sleeve after cutting is long, the number of protrusions 204 can be matched with the position of the cutter 208. A smaller group of protrusions 204 corresponds to the position of the cutter 208. When the shaft 202 rotates one circle, the protrusions 204 squeeze the cutter 208 less times, and the cutting frequency of the cutter 208 is lower, so the sheath can be cut into a longer length; and when the sheath needs to be cut into a shorter length, a larger group of protrusions 204 can be made to correspond to the cutter 208, so that when the shaft 202 rotates one circle, the protrusions 204 squeeze the cutter 208 more times, and the cutting frequency of the cutter 208 is increased, so the sheath can be cut to a shorter state according to demand, so it can be adjusted according to different needs, which is more flexible.

[0026] like Figure 5 As shown, the winding mechanism 3 includes a winding roller 301, the inner wall of the winding roller 301 is rotatably connected to a bidirectional threaded rod 302, the inner wall of the winding roller 301 is slidably connected to a slider 304, the top outer wall of the slider 304 is fixedly connected to a moving block 303, the winding roller 301 is fixedly connected to the output shaft of the motor B5, the slider 304 is threadedly connected to the bidirectional threaded rod 302, the moving block 303 is slidably connected to the outer wall of the winding roller 301, and the winding roller 301 is rotatably connected to the fixed plate 4.

[0027] The above scheme is adopted: by placing the wound cable sheath on the winding roller 301, and fixing the two sides of the sheath by two groups of moving blocks 303, and starting the motor B5 to drive the winding roller 301 to rotate, the sheath can be transported to the base 6 and passed under the cutter 208 for cutting; since the widths of the cable sheaths are different, when the sheaths of different widths are fixed on the winding roller 301, the two groups of sliders 304 can be driven to move by rotating the bidirectional threaded rod 302, and the sliders 304 move to the middle or both sides at the same time under the guidance of the inner wall of the winding roller 301, driving the two groups of moving blocks 303 to move synchronously, and the distance between the two groups of moving blocks 303 can be adjusted to fix the sheath rolls of different widths, so that the sheath rolls are always in the middle position of the winding roller 301, so as to avoid the sheath rolls being offset on the winding roller 301 during the transportation process, thereby affecting the cutting flatness.

[0028] The working principle and use process of this utility model:

[0029] The operator can first place the wound sheath roll on the winding roller 301 so that the two sets of moving blocks 303 are in contact with the two ends of the sheath roll and fix the sheath roll in the middle of the winding roller 301. Since the widths of the sheath rolls are different, the distance between the two sets of moving blocks 303 can be adjusted according to the width of the sheath roll. At this time, the operator can rotate the two-way threaded rod 302 forward or reversely to drive the two sets of sliders 304 to move toward the middle or both sides at the same time under the guidance of the inner wall of the winding roller 301, and drive the two sets of moving blocks 303 to move synchronously. The distance between the two sets of moving blocks 303 can be adjusted to accommodate sheath rolls of different widths, and they can be fixed to keep them in the middle of the winding roller 301 to prevent the winding roller 301 from shifting during transportation and affecting the cutting flatness.

[0030] After the sheath roll is fixed, the motor B5 can be started to drive the winding roller 301 to rotate, and the cable sheath can be transported to the base 6 and pass under the cutter 208. At this time, the motor A201 can be started to drive the rotating shaft 202 and the sleeve 203 to rotate, and the protrusion 204 squeezes the cutter 208, and the spring A207 is forced to contract, so that the cutter 208 moves downward, and a cutting is completed; when the protrusion 204 rotates to disengage from the cutter 208, the spring A207 elastic force causes the cutter 208 to move upward and reset, and the next cutting can be prepared. According to the required length of the sheath after cutting, different numbers of protrusions 204 can be adjusted to correspond to the position of the cutter 208, thereby adjusting the cutting length of the cutter 208. The sleeve 203 can be cut into different lengths by adjusting the frequency. In the process of adjusting the position of the protrusion 204 and the cutter 208, the block 211 can be pulled upwards, and the spring B210 can be forced to shrink, so that the limit of the sleeve 203 can be released and the sleeve 203 can be moved laterally. When a suitable number of protrusions 204 correspond to the position of the cutter 208, the block 211 can be released, and the spring B210 drives the block 211 to pop out due to the elastic force and engage with the slot 209, so that the sleeve 203 and the rotating shaft 202 can be fixed, thereby completing the adjustment, and then the operator does not need to manually cut the sleeve, and the cutting frequency of the cutter 208 can be flexibly adjusted to adapt to the different lengths required for the sleeve, which has higher adaptability and is more convenient to use.
