Abstract
Description
Technical Field
[0001] This invention belongs to the field of V-belt manufacturing technology, and more specifically, relates to a V-belt corner cutting machine and corner cutting method with intermediate feed. Background Technology
[0002] V-belts are unique conveyor belts used for transmitting force and transporting goods. They are characterized by smooth, noiseless operation because the belt is an elastic material, thus mitigating load impact. Edge-cut toothed V-belts are typically made from toothed rubber tape. This requires cutting conventional toothed tape into trapezoidal shapes and then grinding them to ensure the tape's dimensions meet user standards. Currently, the common method for cutting toothed tape involves using grinding wheels on both sides of a belt grinding machine to grind the width of the tape into angled surfaces, resulting in an isosceles trapezoidal cross-section. However, this method is energy-intensive, costly, and inefficient, and it cannot consistently maintain a uniform cutting amount and angle, often resulting in low accuracy and a high scrap rate. Therefore, there is an urgent need to design a V-belt corner-cutting machine that can effectively improve the uniformity and accuracy of the formed V-belt's dimensions and shape, and reduce the scrap rate. Summary of the Invention
[0003] 1. The problem to be solved To address the problems existing in the prior art, this invention aims to provide a V-belt corner cutting machine and corner cutting method with intermediate feed, which can not only effectively reduce power consumption and production costs, but also ensure that the cutting amount and tilt angle of both sides of the toothed tape after cutting are consistent, effectively improving the uniformity and accuracy of the size and shape of the formed V-belt, and reducing the scrap rate of V-belts.

A left baffle and a right baffle are respectively provided on both sides of the opening of the positioning groove. A notch is opened in the middle of the right baffle, and the notch is the cutting area.
[0006] As a further improvement of the present invention, the positioning groove is a flat-bottomed positioning groove, wherein the bottom of the flat-bottomed positioning groove is a flat positioning plate.
[0007] As a further improvement of the present invention, the positioning groove is an arc-shaped bottom positioning groove, wherein the bottom of the arc-shaped bottom positioning groove is an arc-shaped positioning plate.
[0008] As a further improvement of the present invention, an elastic adjustment unit is provided on the outer side of the left baffle, which is used to adjust the left and right horizontal positions of the left baffle.
[0009] As a further improvement of the present invention, the elastic adjustment unit includes a return spring disposed on the outside of the left baffle. One end of the return spring is connected to the left baffle, and the other end of the return spring is connected to the adjustment plate. A horizontally extending limit adjustment rod is disposed on the outside of the adjustment plate. The limit adjustment rod moves horizontally left and right, thereby driving the adjustment plate, the return spring and the left baffle to move horizontally left and right.
[0010] As a further improvement of the present invention, it also includes a blade adjustment mechanism, which includes a horizontal adjustment unit for adjusting the cutting amount of the corner cutting blade. The horizontal adjustment unit includes a motor mounting plate, a corner cutting blade motor is mounted on the bottom of the motor mounting plate, and a corner cutting blade is provided on one side of the corner cutting blade motor. An adjustment base plate is provided above the motor mounting plate, a second slide rail is provided at the bottom of the adjustment base plate, and a second slider is provided at the top of the motor mounting plate to cooperate with the second slide rail. The second slide rail and the second slider cooperate to adjust the cutting amount of the corner cutting blade.
[0011] As a further improvement of the present invention, the blade adjustment mechanism also includes an angle adjustment unit for adjusting the angle position of the cutting blade. The angle adjustment unit includes a base plate hinged to one side of the adjustment substrate, and the base plate and the opening side of the adjustment substrate are provided with an adjustment mechanism for adjusting the size of the opening.
[0012] As a further improvement of the present invention, the blade adjustment mechanism also includes a feed adjustment unit for adjusting the feed mode of the corner cutting blade.

[0014] As a further improvement of the present invention, the cutting method of the corner cutting tool in step S2 includes vertical cutting from above the lower cutting area and oblique cutting from above the front side of the lower cutting area.
[0015] 3. Beneficial effects Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention provides a V-belt corner cutting machine with intermediate feed, wherein a power mechanism is provided on one side of the positioning wheel to drive the positioning wheel to rotate. Under the drive of the power mechanism, the positioning wheel rotates and drives the toothed belt to rotate circumferentially forward. The corner cutting blade above cuts the side of the toothed belt to complete the corner cutting operation on one side of the toothed belt. The overall operation process is smooth. Compared with the previous edge grinding process, it not only greatly improves the production efficiency, but also produces toothed belts with neat edges and corners, good performance, and long service life, but also greatly reduces power consumption, thereby reducing production costs.
[0016] (2) A V-belt corner cutting machine with a central cutting edge according to the present invention has a notch in the middle of the right baffle, which is a cutting area. A corner cutting blade for cutting the side of the toothed tape is provided above the cutting area. The cutting notch is a pre-drilled position for the corner cutting blade, which facilitates the cutting blade to cut at this position. The flat positioning plate can stably support the bottom of the cutting part of the toothed tape, and the left baffle can limit the toothed tape on the left side to prevent the toothed tape from shifting to the left during the cutting process. Under the impact force of the corner cutting blade, the toothed tape usually shifts to the opposite direction of the cutting edge, that is, to the left. The left baffle set on the left side of the flat positioning plate can effectively eliminate this displacement. Therefore, the corner cutting blade can cut smoothly in the cutting area in the middle of the right baffle, which not only avoids affecting the operation of the corner cutting blade, but also effectively ensures that the bottom and left side of the toothed tape always have an L-shaped limiting support during the cutting, thereby improving the cutting accuracy.
[0017] (3) In the V-belt corner cutting machine with intermediate infeed of the present invention, an elastic adjustment unit is also provided on the outer side of the left baffle. The elastic adjustment unit is used to adjust the left and right horizontal position of the left baffle, which can effectively clamp and position the toothed tape from the left side of the planar positioning plate. It can not only effectively prevent the toothed tape from horizontally shifting during the cutting process, but also be applicable to clamping and positioning toothed tapes of different widths. It does not require frequent replacement of the positioning mechanism, effectively reduces production costs, and is conducive to batch use. Attached Figure Description

Detailed Implementation
[0020] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.
[0021] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] The present invention will be further described below with reference to embodiments.
[0023] Example 1 like Figure 1As shown in this embodiment, a V-belt corner cutting machine with intermediate feed includes a positioning wheel 100 and a tensioning wheel 310. The tensioning wheel 310 and the positioning wheel 100 are placed vertically and are located on the same horizontal straight line. One end of the toothed tape 500 is fitted onto the positioning wheel 100, and the other end of the toothed tape 500 is fitted onto the tensioning wheel 310. The tensioning wheel 310 and the positioning wheel 100 are used to fit the toothed tape 500 and position and fix it, ensuring that the forward direction of the toothed tape 500 always remains on a horizontal straight line. This effectively ensures the neatness of the sides of the toothed tape 500 during the subsequent cutting process, thereby effectively improving the performance of the subsequent product. In this embodiment, a tensioning mechanism 300 for driving the tensioning wheel 310 to move horizontally back and forth is provided on the side of the tensioning wheel 310 away from the positioning wheel 100. When the two ends of the toothed tape 500 are respectively fitted onto the positioning wheel 100 and the tensioning wheel 310, when the tensioning mechanism 300 moves away from the positioning wheel 100 (i.e., the rear side), it simultaneously drives the tensioning wheel 310 to move backward, thereby tightening the toothed tape 500. This ensures that the two ends of the toothed tape 500 are tightly fitted onto the positioning wheel 100 and the tensioning wheel 310, thus fixing the toothed tape 500 and providing a stable operating basis for the subsequent cutting work of the corner cutter 600. Specifically, in this embodiment, the tensioning mechanism 300 includes a second hydraulic cylinder 340 extending along the length of the toothed belt 500. One end of the second hydraulic cylinder 340 is provided with a horizontally extending second hydraulic rod 330. The second hydraulic rod 330 is connected to the tensioning wheel 310 via a connector 320. The second hydraulic cylinder 340 drives the second hydraulic rod 330 to move horizontally back and forth, thereby causing the tensioning wheel 310 to move horizontally back and forth. When it is necessary to tension and fix the toothed belt 500, the second hydraulic rod 330... The tensioning wheel 310 moves rearward to achieve tensioning and fixation. When it is necessary to remove the toothed tape 500 from the V-belt corner cutting machine of this embodiment, the second hydraulic rod 330 drives the tensioning wheel 310 to move forward, so that the toothed tape 500 is no longer in a tensioned state. This allows the toothed tape 500 to be easily removed from the positioning wheel 100 and the tensioning wheel 310. The tensioning mechanism 300 controls whether the toothed tape 500 is tensioned or not, making it easy to install, fix, and remove the toothed tape 500. In this embodiment, a power mechanism is provided on one side of the positioning wheel 100 to drive the positioning wheel 100 to rotate. Under the drive of the power mechanism, the positioning wheel 100 rotates, causing the toothed tape 500 to rotate circumferentially forward. The corner cutting blade 600 above cuts the side of the toothed tape 500, completing the corner cutting operation on one side of the toothed tape 500. The overall operation process is smooth. Compared to the previous edge grinding process, this method not only greatly improves production efficiency, but also produces toothed tape 500 with neat edges and corners, good performance, and long service life. It also significantly reduces power consumption, thereby reducing production costs.
[0024] In this embodiment, a positioning mechanism 700 is provided on the side of the positioning wheel 100 away from the tensioning wheel 310. The positioning mechanism 700 includes a U-shaped positioning groove 711, into which a toothed tape 500 is inserted. The bottom of the positioning groove 711 is a positioning plate 710, and the top surface of the positioning plate 710 is in contact with the bottom of the toothed tape 500. Specifically, as shown... Figure 4 and Figure 5 As shown, in this embodiment, the positioning groove 711 is a flat-bottomed positioning groove 711. The toothed tape 500 is inserted into the flat-bottomed positioning groove 711, which can support and limit the toothed tape 500, providing a more stable platform for subsequent corner cutting. The bottom of the flat-bottomed positioning groove 711 is a flat positioning plate 710. The top surface of the flat positioning plate 710 is in contact with the bottom of the toothed tape 500, preventing the front and rear ends of the toothed tape 500 from lifting up during the cutting process, avoiding inconsistent cutting amounts, and effectively improving the stability and accuracy of the cutting. Specifically, in this embodiment, one side of the flat positioning plate 710 extends to near the top edge of the positioning wheel 100, and the height of the front end of the flat positioning plate 710 forms a tangent with the top position of the positioning wheel 100, ensuring that the bottom of the toothed tape 500 is tightly attached to the flat positioning plate 710, resulting in more accurate positioning.
[0025] In this embodiment, a vertically extending left baffle 730 and a right baffle 720 are respectively provided on both sides of the opening of the positioning groove 711. Both the left baffle 730 and the right baffle 720 extend along the length direction of the toothed tape 500 and are used to limit the width of the toothed tape 500 on both sides. The right baffle 720 has a notch in the middle, which is the cutting area. Above the cutting area is a corner cutting blade 600 for cutting the side of the toothed tape 500. The cutting area is a pre-drilled position for the corner cutting blade 600 to make the cutting at this position. The positioning plate 710 provides stable support to the bottom of the cutting section of the toothed tape 500, and the left baffle 730 limits the toothed tape 500 on the left side to prevent it from shifting to the left during the cutting process. Under the impact of the corner cutter 600, the toothed tape 500 usually shifts to the opposite direction of the downward cut, i.e., to the left. The left baffle 730, located to the left of the flat positioning plate 710, can effectively eliminate this displacement. Therefore, the corner cutter 600 cuts in the cutting area in the middle of the right baffle 720, which not only allows for a smooth cutting process and avoids affecting the operation of the corner cutter 600, but also effectively ensures that the bottom and left side of the toothed tape 500 always have L-shaped limiting support during cutting, thereby improving the cutting accuracy.
[0026] In this embodiment, an elastic adjustment unit is also provided on the outer side of the left baffle 730. The elastic adjustment unit is used to adjust the left and right horizontal position of the left baffle 730, which can effectively clamp and position the toothed tape 500 from the left side of the planar positioning plate 710. This not only effectively prevents the toothed tape 500 from shifting horizontally during the cutting process, but also applies to clamping and positioning toothed tapes 500 of different widths. It eliminates the need for frequent replacement of the positioning mechanism 700, effectively reducing production costs and facilitating mass production. Specifically, in this embodiment, two elastic adjustment units are symmetrically arranged along the length direction on the outer side of the left baffle 730, which can effectively prevent the left baffle 730 from tilting at one end during adjustment. At this time, the position of the right baffle 720 is fixed, and only the position of the left baffle 730 needs to be adjusted to easily adjust the distance and tension between the left and right baffles. In this embodiment, the elastic adjustment unit includes a return spring 740 disposed on the outside of the left baffle 730. One end of the return spring 740 is connected to the left baffle 730, and the other end is connected to an adjusting plate 750. The adjusting plate 750 moves towards or away from the left baffle 730, causing the return spring 740 and the left baffle 730 to move to the right or left, thereby adjusting the left limiting position of the toothed tape 500. Specifically, in this embodiment, there is a pair of return springs 740, symmetrically distributed on both sides of the length direction of the left baffle 730, making the limiting adjustment more stable, preventing the left baffle 730 from tilting to one side, and better limiting the toothed tape 500.
[0027] In this embodiment, a horizontally extending limiting adjustment rod 760 is provided on the outer side of the adjusting plate 750. The limiting adjustment rod 760 moves horizontally left and right, thereby driving the adjusting plate 750, the return spring 740, and the left baffle 730 to move horizontally left and right, completing the adjustment of the left and right positions of the left baffle 730. The outer side of the limiting adjustment rod 760 is fixed to the supporting base plate 701 by a support member 770, and the bottom of the planar positioning plate 710, the right baffle 720, the left baffle 730, and the adjusting plate 750 are all located on the top of the supporting base plate 701. In this embodiment, the supporting base plate 701 includes a horizontal base plate for supporting the planar positioning plate 710, the right baffle 720, the left baffle 730, and the adjusting plate 750. A vertical base plate is provided on the outer side of the horizontal base plate away from the right baffle 720. The support member 770 has an L-shaped structure. The support member 770 includes a horizontally extending straight section. One end of the straight section is connected to the outer side of the horizontal base plate. The other end of the straight section is provided with an upwardly extending vertical section. The vertical section has a through hole for the limit adjustment rod 760 to pass through. The outer side of the limit adjustment rod 760 passes through the through hole on the vertical section and is fixed by a nut. The inner end of the limit adjustment rod 760 passes through the through hole on the adjustment plate 750 and is also fixed by a nut. The detachable structure facilitates later maintenance and replacement.
[0028] In this embodiment, the power mechanism includes a rotary motor, which drives the drive wheel 120 to rotate via an output shaft. A belt is fitted around the outer periphery of the drive wheel 120 and the drive wheel 110, and the drive wheel 120 drives the drive wheel 110 to rotate via the belt. In this embodiment, the positioning wheel 100 has a mounting hole 103 at its center. A first rotating shaft 111 is installed in the mounting hole 103. One end of the first rotating shaft 111, away from the positioning wheel 100, is connected to the drive wheel 110 and drives the positioning wheel 100 to rotate under the drive of the drive wheel 110. Specifically, in this embodiment, the positioning wheel 100 and the drive wheel 110 are vertically arranged on the same straight line, which is perpendicular to the running direction of the toothed belt 500. Both ends of the first rotating shaft 111 are fixed to the mounting platform 410 via bearing seats. The mounting platform 410 is part of the mounting frame 400.
[0029] Combination Figure 3 and Figure 4This embodiment also includes a blade adjustment mechanism 200, which adjusts the cutting amount, tilt angle, and feed method of the corner cutting blade 600 to adapt to the cutting of toothed tapes 500 of different sizes and models. Specifically, in this embodiment, the corner cutting blade 600 feeds horizontally, that is, it moves horizontally from the front side of the cutting area to the cutting area until the corner cutting blade 600 abuts against the side of the toothed tape 500 to be repaired. The blade adjustment mechanism 200 includes a horizontal adjustment unit 1 for adjusting the cutting amount of the corner cutting blade 600. The horizontal adjustment unit 1 includes a motor mounting plate 270, on the bottom of which a corner cutting blade motor 610 is mounted. The corner cutting blade motor 610 extends along the length of the toothed tape 500, and a corner cutting blade 600 is provided on one side of the corner cutting blade motor 610. The corner cutting blade 600 is located outside the motor mounting plate 270 to avoid affecting the cutting movement of the corner cutting blade 600. A parallel adjustment base plate 260 is provided above the motor mounting plate 270. A second slide rail 261 extending along the length of the toothed tape 500 is provided at the bottom of the adjustment base plate 260. A second slider 271 cooperating with the second slide rail 261 is provided at the top of the motor mounting plate 270. The second slide rail 261 and the second slider 271 cooperate to adjust the cutting amount of the chamfering blade 600. The cutting amount is adjusted by adjusting the left and right horizontal position of the chamfering blade 600. Specifically, in this embodiment, there are two symmetrically distributed second slide rails 261, located on both sides of the bottom of the adjustment base plate 260. Each second slide rail 261 is provided with two cooperating second sliders 271, which effectively ensures the stability of the connecting movement. The second slider 271 moves left and right on the second slide rail 261 (the left and right horizontal direction here is the direction perpendicular to the length direction of the toothed tape 500), which drives the motor mounting plate 270 and the corner cutting blade motor 610 and corner cutting blade 600 below to move left and right horizontally, thereby adjusting the left and right horizontal position and cutting amount of the corner cutting blade 600.
[0030] like Figure 3As shown, in this embodiment, a second connector 281 with an L-shaped structure is provided on one side of the adjustment base plate 260 along its length. The second connector 281 includes a horizontal section 2 connected to one side of the adjustment base plate 260. A vertical section 2 extending downward is provided on the outer side of the horizontal section 2. A through hole is provided on the vertical section 2 for the horizontal adjustment rod 280 to pass through. One end of the horizontal adjustment rod 280 passes through the through hole on the vertical section 2 and is connected to the top of the motor mounting plate 270 through the fixing member 282. The horizontal adjustment rod 280 and the second slide rail 261 are parallel to each other. Specifically, in this embodiment, the fixing member 282 is set on the top of the motor mounting plate 270. One end of the horizontal adjusting rod 280 is connected to the fixing member 282, and the other end of the horizontal adjusting rod 280 passes through the through hole on the vertical section 2 and is fixed on the vertical section 2 by a fastening nut. By adjusting the left and right positions of the horizontal adjusting rod 280, the motor mounting plate 270 and the chamfering blade 600 below are driven to move horizontally left and right in sequence. The movement is smoother and less strenuous through the cooperation of the slider and the slide rail.
[0031] In this embodiment, the blade adjustment mechanism 200 further includes an angle adjustment unit for adjusting the angle position of the corner cutter 600. The angle adjustment unit includes a base plate 242 hinged to one side of the adjustment base plate 260. An adjustment mechanism for adjusting the opening size is provided on the opening side of the base plate 242 and the adjustment base plate 260. By adjusting the angle of the opening side between the base plate 242 and the adjustment base plate 260 through the adjustment mechanism, the tilt angle of the adjustment base plate 260 and the corner cutter 600 can be adjusted to accommodate cutting at different tilt angles, thus broadening the applicability. The adjustment mechanism includes a connecting block 251 provided on the base plate 242. The connecting block 251 is provided with a through hole for the angle adjustment screw 250 to pass through. The bottom of the angle adjustment screw 250 is connected to the adjustment base plate 260 through a fixing part 252, and the top two ends of the angle adjustment screw 250 are fixed to the connecting block 251 by fastening nuts. Specifically, in this embodiment, a downwardly extending fixing protrusion 244 is provided on the bottom side of the base plate 242 away from the hinge point. The two ends of the fixing protrusion 244 extend to both sides of the base plate 242 in the width direction. A connecting block 251 is provided on one side of the fixing protrusion 244 in the length direction, and an adjusting member 245 parallel to the angle adjusting screw 250 is provided on the other side of the fixing protrusion 244 in the length direction. A sliding groove is provided on the adjusting member 245 along its length direction. A corresponding adjusting slider 246 is provided on the adjusting base plate 260, cooperating with the sliding groove. The adjusting slider 246 is embedded in the sliding groove and moves up and down within it. The angle adjusting screw 250 moves up and down within the through hole of the connecting block 251, driving the adjusting slider 246 to move up and down within the sliding groove, thus improving the stability of the overall structural movement. The tilt angle of the adjusting base plate 260 and the cutting blade 600 is adjusted by adjusting the length of the angle adjusting screw 250 passing through the through hole of the connecting block 251, to adapt to the different angle cutting requirements of the toothed tape 500.
[0032] In this embodiment, the blade adjustment mechanism 200 further includes a feed adjustment unit for adjusting the feed mode of the corner cutting blade 600. The feed adjustment unit includes a first slide rail 223 connected to the base plate 210. A cooperating first slider 224 is provided on the first slide rail 223. The first slider 224 is connected to the angle adjustment unit, and the first slider 224 moves along the length direction of the first slide rail 223 under the drive of the power component. Figures 7-8As shown, the arrangement of the first slide rail 223 determines the cutting method of the corner cutter 600. When the first slide rail 223 is vertically arranged, the corner cutter 600 is located directly above the cutting area. At this time, under the combined action of the first slide rail 223 and the first slider 224, the corner cutter 600 moves vertically into the cutting area, achieving vertical cutting. When the first slide rail 223 is tilted, the corner cutter 600 is located above the front side of the cutting area. At this time, under the combined action of the first slide rail 223 and the first slider 224, the corner cutter 600 moves tilted into the cutting area, achieving tilted cutting. At this time, the tilt angle of the first slide rail 223 is 0°~90°, and the tilt angle of the cutting is 0°~90°.
[0033] Specifically, this embodiment uses a vertical feed method as an example to illustrate the structural orientation of the feed adjustment unit. Figure 2 and Figure 3 The structure shown is for illustrative purposes only and does not limit the orientation. The feed adjustment unit includes vertically extending side plates 241 connected to both sides of the base plate 242 in the width direction. The top of the side plates 241 is connected to a connecting plate 240. The top of the horizontally extending connecting plate 240 is provided with a first slider 224. The base plate 210 is provided with a first slide rail 223 extending in the height direction. The first slider 224 moves back and forth on the first slide rail 223, driving the corner cutting blade 600 directly above the cutting area to move vertically in a straight line towards the cutting notch, thereby achieving vertical feed. In this embodiment, the feed adjustment unit also includes a support plate 230 that is vertically connected to the base plate 210. The support plate 230 extends horizontally, and one side of the support plate 230 in the length direction is fixed on the base plate 210. Limiting plates 231 extend vertically upward on both sides of the support plate 230 in the width direction. One side of the limiting plates 231 in the length direction is also fixed on the base plate 210. The support plate 230 and the limiting plates 231 on both sides are integrally formed, providing a stable mounting platform for the first hydraulic cylinder 220.
[0034] In this embodiment, a first hydraulic cylinder 220 (or a pneumatic drive or other existing drive method) is installed on the support plate 230. Specifically, in this embodiment, the front and rear ends of the first hydraulic cylinder 220 are fixed to the support plate 230 by hydraulic cylinder mounting plates 201, and a connecting rod 202 is connected between the two hydraulic cylinder mounting plates 201. In this embodiment, a first hydraulic rod 221 is provided on the side of the first hydraulic cylinder 220 away from the substrate 210. The first hydraulic rod 221 is connected to a first connecting member 222 with an L-shaped structure. The first connecting member 222 includes a vertical section connected to the first hydraulic rod 221. The bottom of the vertical section extends horizontally towards the substrate 210 and is provided with a horizontal section. The horizontal section is connected to the first slider 224. The first hydraulic cylinder 220 drives the first hydraulic rod 221 to move back and forth along the length of the toothed tape 500, and drives the first slider 224 and the connecting plate 240 below to move back and forth through the first connecting member 222.
[0035] In this embodiment, the blade adjustment mechanism 200 further includes a vertical adjustment unit for adjusting the height position of the corner cutter 600. The vertical adjustment unit includes a third slide rail extending along the height direction of the adjustment base 430, which is also part of the mounting frame 400. In this embodiment, a third slider that cooperates with the third slide rail is provided on the back side of the base plate 210 away from the support plate 230, and an adjustment member is connected to the top of the base plate 210. The adjustment member has an L-shaped structure, and a threaded hole that cooperates with the external thread on the vertical adjustment rod is opened on the horizontal section three of the adjustment member. The bottom of the vertical adjustment rod is connected to the base plate 210, and a vertically downward extending vertical section three is provided on the side of the horizontal section three away from the base plate 210. The bottom of the vertical section three is connected to the top of the adjustment base 430. A turntable is provided at the top of the vertical adjustment rod. The vertical adjustment rod is rotated by the turntable to move up and down, thereby driving the base plate 210 to move up and down, thereby adjusting the height position of the corner cutter 600. The blade adjustment mechanism 200 described above can all be controlled by a fully automatic control system to realize the movement of each component, meeting the need for quick adjustment of the position of the corner cutter 600.
[0036] This embodiment of a corner-cutting method for a V-belt corner-cutting machine with intermediate feed includes the following steps: S1: Tensioning and fixing: One end of the toothed tape 500 is put on the tensioning wheel 310, and the other end of the toothed tape 500 passes through the positioning mechanism 700, so that the toothed tape 500 is inserted into the flat bottom positioning groove 711, and the bottom of the toothed tape 500 is attached to the flat positioning plate 710. At this time, the positioning wheel 100 and the tensioning wheel 310 are close to each other, and the toothed tape 500 is in a relaxed state on the positioning wheel 100 and the tensioning wheel 310. The tensioning mechanism 300 is activated to tighten the toothed tape 500 and fix it. Specifically, in this embodiment, the second hydraulic cylinder 340 of the tensioning mechanism 300 drives the second hydraulic rod 330 to move horizontally back and forth, causing the tensioning wheel 310 to move toward the rear side away from the positioning wheel 100. The bottom of the toothed tape 500 is in contact with the top of the planar positioning plate 710, and the width direction of the toothed tape 500 is restricted by the left baffle 730 and the right baffle 720 respectively, effectively preventing the toothed tape 500 from shifting left and right, thereby achieving the tensioning and fixing of the toothed tape 500. In this embodiment, when it is necessary to cut toothed tapes 500 of different widths, the distance between the left baffle 730 and the right baffle 720 needs to be adjusted. Specifically, in this embodiment, the limiting adjustment rod 760 drives the adjusting plate 750 to move horizontally, thereby driving the reset spring 740 and the left baffle 730 to move closer to or further away from the right baffle 720, thereby adjusting the distance between the left baffle 730 and the right baffle 720, ensuring a good positioning and clamping effect for toothed tapes 500 of different sizes.
[0037] S2: Blade Adjustment: The position and feed method of the corner cutting blade 600 are adjusted by the blade adjustment mechanism 200, and the corner cutting blade 600 is brought into the cutting area and finally abuts against the side of the toothed tape 500 to be repaired. In step S2, the feed method of the corner cutting blade 600 includes vertical feed from directly above the cutting area or inclined feed from the upper front side of the cutting area. In this embodiment, the feed method of the corner cutting blade 600 is first determined by the feed adjustment unit, the height of the corner cutting blade 600 is adjusted by the vertical adjustment unit, the cutting amount of the corner cutting blade 600 is adjusted by the horizontal unit, and finally the tilt angle of the corner cutting blade 600 is adjusted by the angle adjustment unit. After adjusting the corner cutting blade 600 to the most suitable position and the required tilt angle, the corner cutting blade 600, driven by the feed adjustment unit, moves vertically or inclined into the cutting area until it abuts against the side of the toothed tape 500 to be repaired, ready for cutting and repair operation. In this embodiment, during the corner cutting process, the positioning mechanism 700 always restricts the position of both sides of the toothed tape 500's width. That is, the left baffle 730 and the right baffle 720 are always clamped on both sides of the toothed tape 500's width direction. At the same time, the left and right horizontal positions of the left baffle 730 are adjusted by the elastic adjustment unit on the outside of the left baffle 730 during the cutting process, so as to avoid the toothed tape 500 from having left and right horizontal displacement during the cutting process. Therefore, during the corner cutting operation, there will be no inconsistency in the included angle of the working surfaces on both sides of the toothed tape 500, ensuring the accuracy, consistency, and stability of the angle dimensions of the toothed tape 500's corner cutting.
[0038] S3: Corner Cutting Processing: The corner cutting motor 610 and the power mechanism are started to drive the corner cutting blade 600 and the positioning wheel 100 to rotate, respectively, and to cut the corner of the toothed tape 500 to be repaired. In this embodiment, the corner cutting blade 600, driven by the corner cutting motor 610, performs cutting, while the toothed tape 500 moves forward continuously driven by the rotation of the positioning wheel 100, thus successfully completing the cutting operation of one circumference of the toothed tape 500. The linear speed of the corner cutting blade 600 is consistent with the forward speed of the toothed tape 500. The corner cutting motor 610 calculates the time required for the toothed tape 500 to complete one revolution. When the toothed tape 500 has completed one revolution, the corner cutting motor 610 stops, and the power motor of the power mechanism also stops rotating, completing the cutting operation on one side. When the cutting operation is completed on one side of the toothed tape 500, the second hydraulic cylinder 340 of the tensioning mechanism 300 is activated again to drive the second hydraulic rod 330 to move horizontally back and forth, causing the tensioning wheel 310 to move towards the front side closer to the positioning wheel 100. At this time, the toothed tape 500 is no longer in a tensioned state, and the toothed tape 500 can be easily removed from the toothed tape 500 and the tensioning wheel 310 for the side-changing cutting operation. After the toothed tape 500 is switched to the other side, it is fitted onto the positioning wheel 100 and the tensioning wheel 310. At this time, the power motor of the power mechanism is activated again to drive the positioning wheel 100 to rotate, and the corner cutting knife motor 610 is activated to drive the corner cutting knife 600 to perform the cutting operation, completing the cutting operation on the other side of the toothed tape 500, and finally completing the corner cutting work of the V-belt toothed tape 500.
[0039] Example 2 This embodiment of the V-belt chamfering machine with intermediate feed has the same basic structure as Embodiment 1, except that, as follows: Figure 5 As shown, in this embodiment, the positioning groove 711 is an arc-shaped bottom positioning groove 711. The toothed tape 500 is inserted into the arc-shaped bottom positioning groove 711, which can support and limit the toothed tape 500, providing a more stable platform for subsequent corner cutting. The bottom of the arc-shaped bottom positioning groove 711 is an arc-shaped positioning plate 710. The top surface of the arc-shaped positioning plate 710 is in contact with the bottom of the toothed tape 500, preventing the front and rear ends of the toothed tape 500 from lifting up during the cutting process, avoiding inconsistent cutting amounts, and effectively improving the stability and accuracy of the cutting. Specifically, in this embodiment, one side of the arc-shaped positioning plate 710 extends to near the top edge of the positioning wheel 100, and the height of the front end of the arc-shaped positioning plate 710 is not lower than the height of the top of the positioning wheel 100, which can lift the toothed tape 500, ensuring that the bottom of the toothed tape 500 is tightly attached to the arc-shaped positioning plate 710, making the positioning more accurate.
[0040] In this embodiment, elastic adjustment units are also symmetrically arranged on the outer side of the right baffle 720. These elastic adjustment units are used to adjust the left and right horizontal positions of the right baffle 720. Specifically, elastic adjustment units are provided on both sides of the lower notch of the right baffle 720. Each elastic adjustment unit includes a return spring 740 located on the outer side of the right baffle 720. One end of the return spring 740 is connected to the right baffle 720, and the other end is connected to an adjusting plate 750. The adjusting plate 750 moves towards or away from the right baffle 720, causing the return spring 740 and the right baffle 720 to move to the left or right, thereby adjusting the right-side limiting position of the toothed tape 500. Specifically, in this embodiment, there is a pair of return springs 740, symmetrically distributed on both sides of the length of the right baffle 720, making the limiting adjustment more stable and preventing the right baffle 720 from tilting to one side, thus better limiting the toothed tape 500. In this embodiment, a horizontally extending limiting adjustment rod 760 is provided on the outer side of the adjusting plate 750, and the outer side of the limiting adjustment rod 760 is fixed to the supporting base plate 701 by a support member 770. In this embodiment, the supporting base plate 701 includes a horizontal base plate for supporting the positioning plate 710, the right baffle 720, the left baffle 730 and the adjusting plate 750, and vertical base plates extending downward are respectively provided at both ends of the horizontal base plate.
[0041] like Figure 5 As shown, in this embodiment, a position adjustment unit is also provided on the outer side of the support substrate 701. The position adjustment unit includes a vertical adjustment plate 703 connected to the outer side of the vertical substrate. The vertical adjustment plate 703 and the vertical substrate are provided with corresponding vertical adjustment holes 706. The vertical adjustment holes 706 are vertically extending waist-shaped holes. The screw passes through the vertical adjustment holes 706 on the vertical substrate and the vertical adjustment plate 703 in sequence, and the support substrate 701 is fixed on the vertical adjustment plate 703 by the fixing nut 705. The height position of the support substrate 701 can be quickly adjusted through the vertical adjustment holes 706.
[0042] In this embodiment, a horizontal adjustment plate 702 extends horizontally outward from the bottom of the vertical adjustment plate 703. The bottom of the horizontal adjustment plate 702 is fixed to the mounting platform 410. Corresponding horizontal adjustment holes 704 are provided on both the horizontal adjustment plate 702 and the mounting platform 410. The horizontal adjustment holes 704 are horizontally extending, waist-shaped holes. A screw passes through the horizontal adjustment holes 704 on both the mounting platform 410 and the horizontal adjustment plate 702, and a fixing nut 705 secures the horizontal adjustment plate 702 to the mounting platform 410. The horizontal adjustment holes 704 allow for quick adjustment of the horizontal position of the support base plate 701. The horizontal and vertical adjustment holes 704 and 706 respectively position the horizontal and vertical positions of the mechanism 700, making the adjustment more flexible and versatile, and expanding its applicability.
[0043] In this embodiment, a blade cooling unit is also provided above the corner cutter 600. The blade cooling unit includes a cooling nozzle that sprays towards the corner cutter 600. The cooling nozzle is connected to a cooling pipe, and the cooling pipe is connected to a cooling water pipe or a lubricating oil pipe.
