Description

Technical Field

[0001] This invention relates to the field of wire saws, specifically to a take-up and undo assembly for easy loading and unloading of wire reels and a method for loading and unloading wire reels. Background Technology

[0002] With the rapid development of modern industrial technology, the stone processing industry is also gradually upgrading its production processes and equipment. Among these advancements, multi-wire stone cutting machines utilize multiple cutting lines to simultaneously cut raw blocks, enabling the completion of more cutting tasks per unit time, significantly shortening the production cycle, and greatly improving cutting efficiency and quality—a major breakthrough in stone processing technology. However, the cutting process is prone to the following problems: First, the wire saw's take-up and undo assembly requires continuous take-up and undoing of wire, necessitating a sufficiently long wire winding on the reel. This results in a large overall weight on the reel, making it difficult to control the accuracy when adjusting it with a lifting device, and increasing the risk of collisions with the take-up and undo assembly. Consequently, changing the reel is time-consuming and cumbersome, reducing the wire saw's working efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a take-up and undo assembly for easy loading and unloading of reels, as well as a method for loading and unloading reels, which facilitates operators in loading and unloading reels and improves their working efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A wire take-up and undo assembly for easy loading and unloading of wire reels includes a mounting base, a motor, an intermediate shaft, a transport bracket, and a wire reel. The wire reel is detachably inserted into the intermediate shaft. One end of the intermediate shaft is fixedly connected to the output shaft of the motor, and the motor is fixedly mounted on the mounting base. The mounting base has a support shaft hole and a support rod, and the intermediate shaft is rotatably inserted into the support shaft hole. The other end of the intermediate shaft has an outer conical surface, a conical shaft, and a fixing platform. The wire reel has a conical hole and an inner conical surface in the middle. The conical shaft is inserted into the conical hole, and the outer conical surface and the inner conical surface are abutted together. The support rod is fixedly inserted into the side of the mounting base. The transport bracket is slidably inserted onto the support rod; the transport bracket includes two hollow sleeves, a sleeve connecting frame, a handle, and a guide bracket; there are two support rods arranged in parallel, and the two hollow sleeves are movably sleeved onto the support rods; the two ends of the sleeve connecting frame are fixedly connected to the two hollow sleeves respectively; one end of the guide bracket is fixedly connected to the handle, and the other end of the guide bracket is fixedly connected to one of the hollow sleeves; the height of the handle is higher than the height of the hollow sleeve, and a guide slope is formed on the guide bracket; a concave surface with higher ends and a lower middle is formed on the sleeve connecting frame.

[0006] Furthermore, a first gap is formed between the side wall of the fixed platform and the side wall of the reel.

[0007] Furthermore, the reel includes an inner groove, a reel cylinder, and a connecting seat. The reel cylinder and the connecting seat are integrally formed, and the inner groove is formed on both sides of the connecting seat. The conical hole is formed on the connecting seat, and the inner conical surface is formed inside the conical hole.

[0008] Furthermore, the first gap is formed between the side wall of the fixed platform and the side wall of the connecting seat.

[0009] Furthermore, the reel and the intermediate shaft are detachably fixedly connected by bolts; the connecting seat has a plurality of mounting holes, the fixing platform has the same number of screw holes, the number of bolts is the same as the number of mounting holes, and the bolts pass through the mounting holes and are tightened on the screw holes.

[0010] Furthermore, a cover plate is also installed on the other side of the connecting seat. The cover plate has the same number of clearance holes as the mounting holes, and the bolt passes through the clearance holes. A second gap is formed between the side wall of the cover plate and the end face of the tapered shaft.

[0011] Furthermore, a groove is formed on the wheel cylinder, and guardrails are formed on both sides of the groove.

[0012] A method for loading and unloading a reel, utilizing the aforementioned reel-loading and unloading assembly, includes the following steps:

[0013] S01, When installing the spool, slide the transport bracket along the support rod to the end of the support rod to avoid interference between the spool and the intermediate shaft during installation;

[0014] S02, the reel to be installed is sent to the transport bracket by the lifting device, and the reel is sent between the two hollow sleeves;

[0015] S03, by moving the handle, the transport bracket is pushed along the support rod towards the central axis until the conical shaft extends into the inner groove;

[0016] S04. Lift the spool using a lifting device to align the tapered shaft and the tapered hole. Push the spool to the side, adjust the angle of the intermediate shaft, align the mounting hole and the screw hole, and ensure that the outer and inner tapered surfaces abut against each other. Then tighten the bolts and remove the lifting device to complete the spool installation.

[0017] S05, When disassembling the spool, first use a lifting tool to support the spool, move the transport bracket under the spool, and then unscrew the bolts to separate the spool from the intermediate shaft;

[0018] S06, the spool is placed on the transport bracket by the lifting device and the transport bracket is pulled outward so that the spool moves away axially along the intermediate shaft;

[0019] S07. Once the tapered shaft of the spool and the intermediate shaft no longer interfere with each other in the vertical direction, use a lifting tool to lift the spool away, thus completing the spool disassembly.

[0020] By adopting the above-described technical solution of the present invention, at least the following beneficial effects are achieved:

[0021] By designing the inner and outer conical surfaces, when installing the spool, due to their characteristics, the smaller end of the outer conical surface extends from the larger end of the inner conical surface, allowing the conical shaft to be more easily inserted into the conical hole. The spool and the intermediate shaft automatically align and position themselves. When the spool needs to be removed, as the spool and the intermediate shaft separate, the gap between the inner and outer conical surfaces increases, greatly facilitating the operator's loading and unloading of the spool. Furthermore, by placing the spool on the transport bracket before installation, it can be pre-positioned, preventing excessive swaying and collisions with the take-up and unload assembly during lifting operations. The transport bracket allows for quick and easy placement of the spool during installation and facilitates removal during disassembly, improving the loading and unloading efficiency of the take-up and unload assembly.

[0022] The handle allows the transport bracket to be easily moved to a suitable position on the support rod; the guide slope on the guide bracket allows the reel to automatically roll into the concave surface between the two hollow sleeves when placed on the guide bracket.

[0023] By setting the first gap, the inner conical surface and the outer conical surface can better abut against each other, and by controlling the size of the first gap, the fixing platform can provide certain support to the side wall of the spool when the spool is deflected or deformed.

[0024] Fourth, by providing the inner grooves on both sides of the connecting seat, the two inner grooves make the shape of the spool change to an I-shape, which can greatly reduce the weight of the spool and greatly facilitate the loading and unloading of the spool.

[0025] Compared with the prior art, the present invention provides a wire take-up and unwinding assembly and a method for loading and unloading the wire reel, which facilitates the loading and unloading of the wire reel and improves the working efficiency of the wire saw.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see the appendix Figures 1 to 7As shown, the present invention provides a wire saw take-up and unwinding assembly for easy replacement of the wire reel 5, including a mounting base 1, a motor 2, an intermediate shaft 3, a transport bracket 4, and a wire reel 5; the wire reel 5 is detachably inserted into the intermediate shaft 3; one end of the intermediate shaft 3 is fixedly connected to the output shaft of the motor 2, and the motor 2 is fixedly mounted on the mounting base 1; the mounting base 1 has a support shaft hole 11 and a support rod 12 formed thereon, and the intermediate shaft 3 is rotatably inserted into the support shaft hole 11; between the intermediate shaft 3 and the support shaft hole 11... Bearings and bushings can be installed to provide stable support for the intermediate shaft 3 and ensure smooth rotation of the intermediate shaft 3; the other end of the intermediate shaft 3 forms an outer conical surface 31, a conical shaft 32 and a fixed platform 33, and the reel 5 has a conical hole 52 and an inner conical surface 51 in the middle; the conical shaft 32 is inserted into the conical hole 52, and the outer conical surface 31 and the inner conical surface 51 are abutted and connected; the support rod 12 is fixedly inserted into the side of the mounting base 1, and the transport bracket 4 is slidably inserted into the support rod 12. By setting the inner conical surface 51 and the outer conical surface 31, when installing the spool 5, due to the characteristics of the inner conical surface 51 and the outer conical surface 31, the small end of the outer conical surface 31 will extend into the large end of the inner conical surface 51, and the conical shaft 32 can be more easily inserted into the conical hole 52. The spool 5 and the intermediate shaft 3 will automatically align and position themselves. When the spool 5 needs to be removed, as the spool 5 and the intermediate shaft 3 separate, the gap between the inner conical surface 51 and the outer conical surface 31 will become larger and larger, which greatly facilitates the operator in installing and removing the spool 5. In addition, when installing the spool 5, by first placing the spool 5 on the transport bracket 4, the spool can be pre-positioned to avoid excessive swaying of the spool 5 during lifting operations, which could cause it to collide with the take-up and unload assembly. The transport bracket 4 allows the spool 5 to be quickly moved to a suitable position during installation and facilitates its removal during disassembly, thus improving the loading and unloading efficiency of the take-up and unload assembly.

[0043] A first gap 34 is formed between the side wall of the fixed platform 33 and the side wall of the reel 5. By setting the first gap 34, the inner conical surface 51 and the outer conical surface 31 can better abut against each other, and by controlling the size of the first gap 34, the fixed platform 33 can provide certain support to the side wall of the reel 5 when the reel 5 is deflected or deformed.

[0044] Preferably, such as Figure 3 and Figure 4The transport bracket 4 includes two hollow sleeves 41, a sleeve connecting frame 42, a handle 43, and a guide bracket 44. There are two support rods 12 arranged in parallel. The two hollow sleeves 41 are movably sleeved on the support rods 12. The sleeve connecting frame 42 is fixedly connected to both ends of the two hollow sleeves 41 respectively. One end of the guide bracket 44 is fixedly connected to the handle 43, and the other end is fixedly connected to one of the hollow sleeves 41. The handle 43 is higher than the hollow sleeve 41. A guide slope 45 is formed on the guide bracket 44. A concave surface 46, higher at both ends and lower in the middle, is formed on the sleeve connecting frame 42. The handle 43 allows the transport bracket 4 to be easily moved to a suitable position on the support rod 12; the guide slope 45 is provided on the guide bracket 44, which allows the spool 5 to automatically roll into the concave surface 46 between the two hollow sleeves 41 when it is placed on the guide bracket 44.

[0045] Preferably, such as Figure 5 and Figure 6 As shown, the spool 5 includes an inner groove 53, a spool cylinder 54, and a connecting seat 55. The spool cylinder 54 and the connecting seat 55 are integrally formed. The inner groove 53 is formed on both sides of the connecting seat 55. The conical hole 52 is formed on the connecting seat 55, and the inner conical surface 51 is formed in the conical hole 52. By providing the inner groove 53 on both sides of the connecting seat 55, the two inner grooves 53 make the shape of the spool 5 I-shaped, which can greatly reduce the weight of the spool 5 and greatly facilitate the loading and unloading of the spool 5. Preferably, the first gap 34 is formed between the side wall of the fixed platform 33 and the side wall of the connecting seat 55.

[0046] Preferably, such as Figure 3 As shown, the reel 5 and the intermediate shaft 3 are detachably fixed together by bolts 6. This facilitates installation and disassembly by the operator.

[0047] Preferably, the connecting seat 55 has a plurality of mounting holes 56, and the fixing platform 33 has the same number of screw holes 35. The number of bolts 6 is the same as the number of mounting holes 56. The bolts 6 pass through the mounting holes 56 and are tightened into the screw holes 35. Additionally, a cover plate 7 is installed on the other side of the connecting seat 55. The cover plate 7 has the same number of clearance holes 71 as the mounting holes 56. The bolts 6 pass through the clearance holes 71, then through the mounting holes 56, and finally are tightened into the screw holes 35. This allows the connecting seat 55 to be clamped between the cover plate 7 and the fixing platform 33. The cover plate 7 can evenly transmit the tightening pressure of the bolts 6 to the connecting seat 55, thus making the installation of the reel 5 more stable.

[0048] Furthermore, a second gap 72 is formed between the side wall of the cover plate 7 and the end face of the conical shaft 32. Similarly, the second gap 72 allows the inner conical surface 51 and the outer conical surface 31 to better abut against each other, and by controlling the size of the second gap 72, the cover plate 7 provides some support to the side wall of the spool 5 when the spool 5 experiences offset deformation. This further improves the stability of the spool 5 during installation.

[0049] Preferably, such as Figure 6 As shown, a wire groove 57 is formed on the wheel cylinder 54, and guardrails 58 are formed on both sides of the wire groove 57. Therefore, the wire can be stored in the wire groove 57 between the guardrails 58.

[0050] A method for loading and unloading a reel, utilizing the aforementioned reel-loading and unloading assembly, includes the following steps:

[0051] S01, When installing the spool 5, slide the transport bracket 4 along the support rod 12 to the end of the support rod 12 to avoid interference between the spool 5 and the intermediate shaft 3 during installation;

[0052] S02, the spool 5 to be installed is sent to the transport bracket 4 by the lifting device, and the spool 5 is sent between the two hollow sleeves 41;

[0053] S03, by moving the handle, the transport bracket 4 is pushed along the support rod 12 toward the intermediate shaft 3 until the conical shaft 32 extends into the inner groove 53;

[0054] S04, lift the spool 5 with the lifting tool so that the tapered shaft 32 and the tapered hole 52 are aligned, push the spool 5 to the side, adjust the angle of the intermediate shaft 3, align the mounting hole 56 and the screw hole 35 so that the outer tapered surface 31 and the inner tapered surface 51 abut against each other, then tighten the bolt 6 and remove the lifting tool to complete the installation of the spool 5;

[0055] S05, When disassembling the spool 5, first use a lifting tool to support the spool 5, move the transport bracket 4 to below the spool 5, and then unscrew the bolt 6 to separate the spool 5 from the intermediate shaft 3;

[0056] S06, the spool 5 is placed on the transport bracket 4 by the lifting device and the transport bracket 4 is pulled outward, so that the spool 5 moves away axially along the intermediate shaft 3;

[0057] S07, until the tapered shaft 32 of the spool 5 and the intermediate shaft 3 no longer interfere in the vertical direction, use a lifting tool to lift the spool 5 away, and complete the disassembly of the spool 5.

[0058] Compared with the prior art, the present invention provides a wire take-up and untake-up assembly and a method for loading and unloading the wire reel, which facilitates the loading and unloading of the wire reel 5 and improves the working efficiency of the wire saw.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
