Description

Technical Field

[0001] This utility model relates to the field of wire saw technology, specifically an improved wire cutting unit. Background Technology

[0002] Wire saws are now used in stone cutting. A wire saw typically consists of a support frame and a wire cutting unit. The wire cutting unit includes a mounting frame, multiple rollers that can be rotatably mounted on the mounting frame, two sets of take-up and undo systems, and a cutting wire. The cutting wire is drawn out from the first take-up and undo system and reciprocates around each roller to form a cutting mesh. The end of the cutting wire is connected to the second take-up and undo system.

[0003] However, the wire cutting unit of existing wire saw machines has the following defects in actual use:

[0004] 1. By setting two sets of take-up and unwinding systems at the left and right ends of the wire cutting unit respectively, when adjusting the position of the cutting wire, replacing the cutting wire, or performing wire breakage and reconnection work, each set of take-up and unwinding systems requires one person to operate, and the roller position requires at least one person to operate. Therefore, the entire operation process requires at least three people to work together, which is relatively troublesome and inefficient.

[0005] 2. Existing wire cutting units require multiple guide rollers for each take-up and pay-off system, which not only increases the probability of failure in the take-up and pay-off system, but also increases the implementation cost. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides an improved wire cutting unit, which solves the problems of cumbersome operation of the cutting wire, low efficiency, and the need for multiple guide wheels, which increases the probability of failure and implementation cost.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An improved wire cutting unit includes a support body, four rollers rotatably mounted on the support body, two sets of take-up and unwinding systems, and a sliding mechanism; an installation structure is provided on the outer side of either the left or right end of the support body, and both sets of take-up and unwinding systems are slidably connected to the installation structure through the sliding mechanism.

[0009] Furthermore, each of the aforementioned take-up and release systems includes a take-up and release wheel assembly and a guide wheel assembly, and the sliding mechanism includes a first sliding assembly and a second sliding assembly;

[0010] Both sets of take-up and release systems have their take-up and release wheel assemblies slidably connected to the mounting structure via a first sliding assembly, and both sets of take-up and release systems have their guide wheel assemblies slidably connected to the mounting structure via a second sliding assembly.

[0011] Furthermore, the guide wheel assembly includes a guide wheel body, a swing arm, a first drive motor, and a first support; the first support is slidably connected to the mounting structure via a second sliding assembly, the first drive motor is mounted on the first support, one end of the swing arm is connected to the output end of the first drive motor, and the guide wheel body is rotatably connected to the other end of the swing arm.

[0012] Furthermore, the first drive motor is a servo motor.

[0013] Furthermore, the take-up and release wheel assembly includes a take-up and release wheel body, a second drive motor, and a second support; the second support is slidably connected to the mounting structure via a first sliding component, the second drive motor is mounted on the second support, and the take-up and release wheel body is connected to the output end of the second drive motor.

[0014] Furthermore, the installation structure includes an installation base extending outward from the outer side of the lower part of the support body and an installation crossbeam located in the middle of the support body, with the installation crossbeam positioned above the installation base; the take-up and take-down wheel assemblies of both sets of take-up and take-down systems are slidably connected to the installation base via a first sliding assembly, and the guide wheel assemblies of both sets of take-up and take-down systems are slidably connected to the installation crossbeam via a second sliding assembly.

[0015] Furthermore, the first sliding assembly includes at least two first guide rails disposed on the upper surface of the mounting base, a plurality of first sliders slidably disposed on each first guide rail, a first rack disposed on the mounting base, and a third drive motor disposed on the two take-up and release wheel assemblies. The bottom of each take-up and release wheel assembly is connected to at least two first sliders, and the output end of each third drive motor is engaged with the first rack through a first gear.

[0016] Furthermore, the second sliding assembly includes at least two second guide rails disposed on the outer surface of the mounting beam, a plurality of second sliders slidably disposed on each second guide rail, a second rack disposed on the mounting beam, and a fourth drive motor disposed on the two guide wheel assemblies. Each guide wheel assembly is connected to at least two second sliders, and each fourth drive motor meshes with the second rack through a second gear.

[0017] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0018] 1. By setting an installation structure on the outer side of either the left or right end of the support body, and slidingly connecting both sets of take-up and unwinding systems to the installation structure via a sliding mechanism, in actual use, on the one hand, when it is necessary to adjust the position of the cutting wire, replace the cutting wire, or perform wire breakage and splicing work, only one person needs to operate both sets of take-up and unwinding systems, and another person needs to operate the roller position. In this way, the entire operation can be completed by only two people working together, and the two people's working positions are close to each other, eliminating the need for a middleman to relay messages, making communication and cooperation easier, thus simplifying the entire operation process and improving operational efficiency. On the other hand, since both sets of take-up and unwinding systems are slidably assembled with the installation structure, the positions of the two sets of take-up and unwinding systems can be slidably adjusted according to actual needs during use, which can improve the flexibility of use.

[0019] 2. By designing each take-up and unwinding system's guide wheel assembly to include only one guide wheel body, and connecting the guide wheel body to the first drive motor via a swing arm, the torque of the first drive motor can be quickly adjusted based on the torque feedback from the connected swing arm during actual use. This ensures consistent tension in the cutting wire, thereby guaranteeing equipment operational stability. Furthermore, since each take-up and unwinding system requires only one guide wheel body, the probability of malfunctions is reduced, minimizing impact on production and lowering implementation costs.

[0033] Mounting structure 5, mounting base 51, mounting beam 52. Detailed Implementation

[0034] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Please see the appendix Figures 1 to 6 As shown, this utility model provides an improved wire cutting unit 100, which includes a support body 1, four rollers 2 rotatably mounted on the support body 1, two sets of take-up and undo systems 3, and a sliding mechanism 4. The support body 1 serves as the support frame for the entire improved wire cutting unit 100. The rollers 2 are used to wind the cutting wire 200 and drive the cutting wire 200 for transmission. Each roller 2 is equipped with a fifth drive motor 21 at one end to drive the roller 2 to rotate. The take-up and undo systems 3 are used to undo or take up the cutting wire 200. The sliding mechanism 4 allows for sliding adjustment of the take-up and undo systems 3.

[0036] An installation structure 5 is provided on the outer side of either the left or right end of the support body 1, and both sets of wire take-up and take-down systems 3 are slidably connected to the installation structure 5 through a sliding mechanism 4.

[0037] This invention features an installation structure 5 on the outer side of either the left or right end of the support body 1, with both take-up and unwinding systems 3 slidably connected to the installation structure 5 via a sliding mechanism 4. This allows for several advantages in practical use. First, when adjusting the position of the cutting wire 200, replacing the cutting wire 200, or performing wire breakage and reconnection work, only one person needs to operate each of the two take-up and unwinding systems 3, and another person needs to operate the roller 2. This means the entire operation can be completed with just two people working together. Furthermore, the close proximity of these two individuals eliminates the need for intermediaries, making communication and coordination easier and simplifying the entire process while improving efficiency. Second, because both take-up and unwinding systems 3 are slidably assembled with the installation structure 5, their positions can be adjusted as needed, enhancing flexibility.

[0038] In this utility model, each set of the take-up and release system 3 includes a take-up and release wheel assembly 31 and a guide wheel assembly 32, wherein the take-up and release wheel assembly 31 is used to take up or release the cutting wire 200; the sliding mechanism 4 includes a first sliding component 41 and a second sliding component 42;

[0039] The take-up and take-down wheel assemblies 31 of both sets of take-up and take-down systems 3 are slidably connected to the mounting structure 5 through the first sliding assembly 41, so that both take-up and take-down wheel assemblies 31 can be slidably adjusted through the first sliding assembly 41; the guide wheel assemblies 32 of both sets of take-up and take-down systems 3 are slidably connected to the mounting structure 5 through the second sliding assembly 42, so that both guide wheel assemblies 32 can be slidably adjusted through the second sliding assembly 42.

[0040] Please refer to the following embodiments of this utility model. Figure 5 As shown, the guide wheel assembly 32 includes a guide wheel body 321, a swing arm 322, a first drive motor 323, and a first support 324. The first support 324 is slidably connected to the mounting structure 5 through a second sliding assembly 42, so that the first support 324 can slide relative to the mounting structure 5. The first drive motor 323 is mounted on the first support 324 to support the first drive motor 323. One end of the swing arm 322 is connected to the output end of the first drive motor 323, and the guide wheel body 321 is rotatably connected to the other end of the swing arm 322.

[0041] This invention designs each take-up and unwinding system 3 to include only one guide wheel body 321 in its guide wheel assembly 32, and connects the guide wheel body 321 to the first drive motor 323 via a swing arm 322. This allows for rapid torque adjustment of the first drive motor 323 based on torque feedback from the swing arm 322 during use, ensuring consistent tension of the cutting wire 200 and thus guaranteeing equipment stability. Furthermore, since each take-up and unwinding system 3 requires only one guide wheel body 321, the probability of malfunctions is reduced, minimizing impact on production and lowering implementation costs.

[0042] In one specific embodiment of this utility model, in order to achieve torque adjustment more accurately, the first drive motor 323 is a servo motor.

[0043] Please refer to the following embodiments of this utility model. Figure 6 As shown, the take-up and release reel assembly 31 includes a take-up and release reel body 311, a second drive motor 312, and a second support 313. The second support 313 is slidably connected to the mounting structure 5 through a first sliding component 41, allowing the second support 313 to be slidably adjusted relative to the mounting structure 5. The second drive motor 312 is mounted on the second support 313 to support the second drive motor 312. The take-up and release reel body 311 is connected to the output end of the second drive motor 312. During operation, the second drive motor 312 drives the take-up and release reel body 311 to rotate forward or backward, thereby achieving take-up or release of line.

[0044] In some embodiments of this utility model, the mounting structure 5 includes a mounting base 51 extending outward from the outer side of the lower part of the support body 1 and a mounting beam 52 located in the middle of the support body 1, with the mounting beam 52 positioned above the mounting base 51; the take-up and take-down wheel assemblies 31 of the two sets of take-up and take-down systems 3 are slidably connected to the mounting base 51 via a first sliding assembly 41, and the guide wheel assemblies 32 of the two sets of take-up and take-down systems 3 are slidably connected to the mounting beam 52 via a second sliding assembly 42.

[0045] This utility model, through the design of the installation structure 5 including the mounting base 51 located at the lower part of the support body 1 and the mounting beam 52 located in the middle of the support body 1, and the take-up and release wheel assembly 31 is slidably connected to the mounting base 51 through the first sliding assembly 41, and the guide wheel assembly 32 is slidably connected to the mounting beam 52 through the second sliding assembly 42, can ensure that the take-up and release wheel assembly 31 and the guide wheel assembly 32 can cooperate with each other without interfering with each other during the operation.

[0046] Please refer to the following embodiments of this utility model.

The bottom of each take-up and put-down wheel assembly 31 is connected to at least two first sliders 412, and the output end of each third drive motor 414 is engaged with the first rack 413 through a first gear 415. In a specific implementation of this invention, two first guide rails 411 can be arranged parallel to each other on the upper surface of the mounting base 51, and each first guide rail 411 can be slidably assembled with the bottom of each take-up and put-down wheel assembly 31 through two first sliders 412, that is, the bottom of each take-up and put-down wheel assembly 31 is provided with four first sliders 412, which can ensure that the take-up and put-down wheel assembly 31 can slide and adjust more smoothly. In practical operation, when it is necessary to slide and adjust a certain take-up and release wheel assembly 31, it is only necessary to control the third drive motor 414 on the take-up and release wheel assembly 31 to rotate forward or reverse, so as to drive the take-up and release wheel assembly 31 to slide and adjust. Similarly, when it is necessary to slide and adjust two take-up and release wheel assemblies 31 at the same time, it is only necessary to control the third drive motor 414 on the two take-up and release wheel assemblies 31 to rotate forward or reverse.

[0047] Please refer to the following embodiments of this utility model. Figure 4 As shown, the second sliding assembly 42 includes at least two second guide rails 421 disposed on the outer surface of the mounting beam 52, a plurality of second sliders 422 slidably disposed on each second guide rail 421, a second rack 423 disposed on the mounting beam 52, and a fourth drive motor 424 disposed on the two guide wheel assemblies 32. Each guide wheel assembly 32 is connected to at least two second sliders 422, and each fourth drive motor 424 is engaged with the second rack 423 through a second gear 425. In a specific implementation of this invention, two second guide rails 421 can be arranged parallel to each other on the outer surface of the mounting beam 52, and each second guide rail 421 can be slidably assembled with each guide wheel assembly 32 through two second sliders 422, that is, each guide wheel assembly 32 is equipped with four second sliders 422, which can ensure that the guide wheel assembly 32 can slide and adjust more smoothly. In practical operation, when it is necessary to slide and adjust a certain guide wheel assembly 32, it is only necessary to control the fourth drive motor 424 on the guide wheel assembly 32 to rotate forward or reverse, so as to drive the guide wheel assembly 32 to slide and adjust. Similarly, when it is necessary to slide and adjust two guide wheel assemblies 32 at the same time, it is only necessary to control the fourth drive motor 424 on the two guide wheel assemblies 32 to rotate forward or reverse.
