Description

Technical Field

[0001] This utility model relates to the field of jewelry processing equipment technology, and in particular to a wire feeding mechanism for rope and chain processing equipment. Background Technology

[0002] In the field of jewelry processing equipment, especially in the processing of metal wire, the accuracy and stability of the wire feeding mechanism directly affect product quality and production efficiency. Traditional wire feeding mechanisms typically employ simple clamping and pushing methods, but in practical applications, problems such as wire slippage, inconsistent wire length, or positional misalignment can easily occur. For example, when making delicate jewelry chains or decorative pieces, continuous and uniform feeding of metal wire is required. However, existing mechanisms, due to insufficient clamping force or improper release timing, may cause the wire to loosen during feeding, resulting in decreased processing accuracy or even wire damage. Therefore, how to design a mechanism that can reliably clamp and release the wire and achieve precise step-by-step wire feeding has become a technical problem that needs to be solved in this field.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0020] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0021] In an embodiment of this utility model, a wire feeding mechanism 100 for a rope and chain processing equipment is provided, which is used to straighten the wound metal wire into a straight wire, and then to ensure that the wire feeding length is accurate and consistent through a step-by-step wire feeding method, thereby improving the processing accuracy.

[0022] like Figures 1-7 As shown, the wire feeding mechanism 100 for rope and chain processing equipment includes: a fixing block 10, a wire pressing assembly 20, a wire feeding assembly 30, a third driving device (not shown in the figure), and a return spring 40.

[0023] The fixing block 10 is provided with a mounting block 11 and a sliding groove 101. The sliding groove 101 is spaced apart from the mounting block 11. The wire pressing assembly 20 is provided on the mounting block 11. The wire feeding assembly 30 can slide along the sliding groove 101 to move closer to or further away from the wire pressing assembly 20.

[0024] Specifically, the wire pressing assembly 20 includes a first carrier 21 disposed on the mounting block 11, a first cover 22 covering the first carrier 21, a first pressing member 23 abutting against the side of the first cover 22 away from the first carrier 21, and a first driving device (not shown in the figure) disposed on the side of the first pressing member 23 away from the first cover 22.

[0025] The first carrier 21 has a first groove 201. A metal wire is placed within the first groove 201 and can move axially along it. When the first cover 22 closes the first carrier 21, it presses the metal wire firmly into the first groove 201, preventing relative movement between the metal wire and the groove. A first driving device presses the first pressure member 23 to compress the metal wire within the first groove 201. When it is necessary to push the metal wire forward from the first groove 201, the first driving device moves upward, and the first cover 22 no longer presses the metal wire. It should be noted that the first driving device can be a conventional structure or device such as a cam crank, cylinder, or motor, which will not be described in detail here.

[0026] Furthermore, the mounting block 11 has a vertically connected fixing hole 111 and a pressing hole 112. The mounting block 11 is generally rectangular. The first carrier 21 and the first cover 22 together form a cylinder, and both are inserted into the fixing hole 111. The first pressing member 23 may be columnar, with one end extending into the pressing hole 112 and abutting against the first cover 22. That is, the first pressing member 23 and the first cover 22 are arranged perpendicularly.

[0027] In this embodiment, the first cover 22 includes a first segment 221 and a second segment 222 spaced apart. A first pressing member 23 abuts against the first segment 221. That is, the first pressing member 23 presses the metal wire by pressing the first segment 221. The second segment 222 does not press against the first carrier 21, so the first wire groove 201 portion located between the second segment 222 and the first carrier 21 only serves a guiding function. The second segment 222 abuts against the first carrier 21 through a retaining ring 24 to prevent the second segment 222 from detaching from the first carrier 21. The retaining ring 24 extends out of the retaining hole 111.

[0028] Furthermore, the fixing block 10 has a rectangular mounting groove 102. The mounting block 11 is housed within the mounting groove 102. L-shaped limiting blocks 12 and clamping blocks 13 are respectively provided on the left and right sides of the mounting groove 102 relative to the direction of movement of the metal wire. One side of the L-shaped limiting block 12 abuts against the side of the fixing block 10 where the first pressing member 23 is located, thereby preventing the mounting block 11 from detaching from the mounting groove 102 on this side. The clamping block 13 is detachably fixed to the inner wall of the mounting groove 102 and abuts against the mounting block 11 at an angle, thus forming a half-dovetail groove on this side of the mounting groove 102, preventing the mounting block 11 from detaching. In addition, the mounting groove 102 is first machined into a rectangular groove, which is easier to process, and then combined with the clamping block 13 to form a half-dovetail groove, achieving the anti-detachment effect.

[0029] In one embodiment of the present invention, the wire feeding assembly 30 includes a sliding platform 31 slidably connected in the sliding groove 101, a second carrier 32 disposed on the sliding platform 31, a second cover 33 covering the second carrier 32, and a second driving device (not shown in the figure) disposed on the side of the second cover 33 away from the second carrier 32.

[0030] Specifically, a second groove 301 is provided on the second carrier 32. The second groove 301 is on the same straight line as the first groove 201 to prevent the metal wire from bending during transportation. When the second cover 33 closes the second carrier 32, it presses the metal wire into the second groove 301, at which time the metal wire will not move relative to the second groove 301. The second drive device is used to press the second cover 33 to press the metal wire in the second groove 301, and can move with the sliding platform 31. It should be noted that the second drive device can be a conventional structure or device such as a cam crank, cylinder, or lifting motor that can slide with the sliding platform 31, which will not be described in detail here.

[0031] Furthermore, in one embodiment, the sliding groove 101 is directly machined as a dovetail groove. The bottom portion of the sliding platform 31 is shaped to fit the dovetail groove.

[0032] In another embodiment, one side of the sliding groove 101 is a half-dovetail groove, while the other side is a right-angled surface relative to the bottom surface, to reduce machining difficulty. A triangular prism 34 is provided between the right-angled surface and the sliding platform 31. The cross-section of the triangular prism 34 can be a right-angled triangle. One side of the triangular prism 34 is detachably connected to the right-angled surface of the sliding groove 101, so that the side of the triangular prism 34 near the sliding platform 31, the side of the sliding groove 101 away from the right-angled surface, and the bottom surface of the sliding groove 101 form a dovetail groove. In this case, the triangular prism 34 is equivalent to a wedge inserted between the sliding platform 31 and the inner wall of the sliding groove 101, thereby adjusting the friction between them.

[0033] In some embodiments, the sliding platform 31 has a rectangular placement groove 311. The second carrier 32 and the second cover 33 are both generally rectangular strips. The second carrier 32 and the second cover 33 are stacked vertically within the placement groove 311, with the second cover 33 positioned above the second carrier 32. Further, the sidewall of the placement groove 311 has a clearance hole 312. The second carrier 32 and the second cover 33 have a coaxial slot 302. The width of the slot 302 is greater than the width of the clearance hole 312. The sliding platform 31 also has a T-shaped locking block 35. The wider end of the T-shaped locking block 35 extends into the slot 302, while the narrower end passes through the clearance hole 312. Therefore, the T-shaped locking block 35 cannot detach horizontally from the clearance hole 312, and also restricts the autonomous axial movement of the second carrier 32 and the second cover 33.

[0034] In one embodiment of this utility model, the sliding platform 31 has a receiving hole 313, and a baffle 36 is provided at the end away from the pressure assembly 20. The baffle 36 is used to close one end of the receiving hole 313. However, the end of the receiving hole 313 near the pressure assembly 20 is not closed. The baffle 36 can also limit the maximum stroke of the sliding platform 31 moving near the pressure assembly 20 by abutting against one end of the sliding groove 101 with its own edge extension.

[0035] The sliding platform 31 has a threaded hole 314 through the baffle 36 on the side away from the pressure assembly 20, and the threaded hole 314 is threaded to one end of the screw 37. A third driving device (not shown) is used to push the end of the screw 37 away from the sliding platform 31, causing the sliding platform 31 to slide accordingly. That is, the third driving device drives the sliding platform 31 to slide along the direction closer to the pressure assembly 20. It should be noted that the third driving device can be a conventional structure or device such as a cam crank, cylinder, or motor, which will not be described in detail here. The force applied to the sliding platform 31 by the third driving device can be changed by changing the length of the screw 37 extending beyond the sliding platform 31; the longer the screw 37 extends, the greater the force applied by the third driving device to push the same distance.

[0036] A return spring 40 is disposed within the receiving hole 313, with one end abutting against the baffle 36 and the other end abutting against a predetermined portion of the mounting block 11 or the fixing block 10. The return spring 40 is used to cause the sliding platform 31 to slide away from the pressure assembly 20. That is, when the third drive device releases the drive on the sliding platform 31, the compressed return spring 40 will cause the sliding platform 31 to return to its original position. Furthermore, a buffer rod 39 is also vertically provided at the baffle 36. The buffer rod 39 is used to contact the external structure to absorb the inertial kinetic energy generated when the sliding platform 31 returns to its original position.

[0037] Furthermore, a sleeve 38 with one end closed is provided inside the receiving hole 313, and the return spring 40 is disposed inside the sleeve 38. The closed end of the sleeve 38 abuts against a predetermined position on the mounting block 11 or the fixing block 10. The sleeve 38 can provide a certain degree of protection for the return spring 40, preventing the part of the return spring 40 extending out of the receiving hole 313 from interfering with other components or debris, thereby affecting the return effect of the return spring 40.

[0038] In summary, the wire feeding mechanism 100 for rope and chain processing equipment provided by this utility model, during the wire feeding process, involves the second driving device pressing the second cover 33 to compress the metal wire within the second groove 301 of the second carrier 32. Simultaneously, the third driving device drives the sliding platform 31 to slide along the direction close to the pressing assembly 20, pushing the metal wire through the first groove 201. After the wire is fed into place, the first driving device presses the first pressing member 23, causing the first cover 22 to press the metal wire within the first groove 201. At this point, the second and third driving devices are removed, and the wire feeding assembly 30 slides back away from the pressing assembly 20 under the action of the return spring 40. Since the metal wire is fixed by the pressing assembly 20, relative movement occurs between it and the second groove 301, thus completing one wire feeding cycle. This alternating pressing and releasing method ensures that the wire remains under control during the feeding process, preventing slippage and deviation. Therefore, by alternating pressing actions of the wire pressing assembly 20 and the wire feeding assembly 30, step-by-step wire feeding is achieved, ensuring accurate and consistent wire length and improving processing precision. The automatic return mechanism of the return spring 40 reduces the frequent operation of the drive device, improving equipment efficiency and lifespan. Finally, the overall structure is compact and suitable for high-requirement operations involving fine wires in jewelry processing, enhancing production stability and product quality.

[0039] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
