Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire production and processing, in particular to a novel enameled wire pay-off device. Background Art

[0002] Currently, during the production process, enameled wire needs to be wound into enameled wire coils and then transferred to the rotating shaft of the pay-off mechanism by a forklift. Due to the heavy weight of the enameled wire coils, it is not easy to install them on the rotating shaft of the pay-off mechanism. The enameled wire coils were originally transported by forklifts, which was difficult and labor-intensive. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a new type of enameled wire pay-out device, which is provided with a hydraulic cylinder. After the rotating shaft passes through the installation through hole in the middle of the enameled wire roll, it can be lifted off the ground with the help of the hydraulic cylinder, and then moved to the required position through the universal wheel. There is no need to use a forklift. The enameled wire roll can be easily raised and lowered by the pay-out shaft, and the pay-out is smooth, which brings great convenience to employees' operations and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel enameled wire pay-off device, comprising:

[0005] The enameled wire supporting mobile mechanism includes side frames, longitudinal beams, transverse connecting beams, universal wheels and wheel brakes. There are two side frames, and the upper and lower ends of the rear sides of the two side frames are fixedly connected by transverse connecting beams. The bottom of each side frame is fixedly connected to the longitudinal beam, and the front and rear sides of the bottom of each side frame are respectively installed with universal wheels, and the universal wheels are installed with wheel brakes.

[0006] A lifting wire-paying mechanism is installed between the bottoms of the two side frames, and the lifting wire-paying mechanism is connected to the hydraulic control mechanism;

[0007] The pay-out resistance adding mechanism is installed in the middle of the upper horizontal connecting beam.

[0008] When the enameled wire coil needs to be placed on the lifting wire pay-off mechanism, the hydraulic control mechanism controls the lifting wire pay-off mechanism to lower its height. After the enameled wire coil is installed, the hydraulic control mechanism controls the lifting wire pay-off mechanism to rise, so that the bottom of the enameled wire coil leaves the ground, and then the wheel brake is released. The wire pay-off frame composed of the side frame, longitudinal beam and transverse connecting beam is moved to the required position with the help of the universal wheel, and then the universal wheel is locked with the help of the wheel brake. Then the enameled wire on the enameled wire coil is paid out, and the wire pay-off resistance adding mechanism is placed on the front side of the enameled wire coil. The friction between the enameled wire coil and the wire pay-off resistance adding mechanism prevents the enameled wire coil from rotating excessively due to excessive tension on the enameled wire, thereby ensuring that the enameled wire on the enameled wire coil is released stably.

[0009] Furthermore, the lifting wire-paying mechanism includes a support block, a mounting sleeve, a hydraulic cylinder, a rotating shaft support, and a wire-paying rotating shaft. The two side frames are fixedly connected to the sides of the bottom centers close to each other. The top of each support block is fixedly connected to the bottom end of the hydraulic cylinder via a mounting sleeve. The top of each hydraulic cylinder is fixedly connected to a rotating shaft support. Each rotating shaft support is provided with a limiting groove. The two ends of the wire-paying rotating shaft are respectively overlapped in the limiting grooves on the two rotating shaft supports. The support block and the mounting sleeve are used to install the hydraulic cylinder. The lifting of the hydraulic cylinder can drive the rotating shaft support to lift and lower, thereby driving the wire-paying rotating shaft to lift and lower. Since the wire-paying rotating shaft is inserted into the mounting through-hole in the middle of the enameled wire coil, it is convenient to drive the enameled wire coil to lift and lower as needed, thereby realizing the easy raising and lowering of the wire-paying rotating shaft of the enameled wire coil.

[0010] Furthermore, the lifting wire-paying mechanism further includes a rotating sleeve, a retaining ring, and a limit pin. Two rotating sleeves are rotatably connected to the wire-paying shaft, and retaining rings are fixedly connected to the outer circumferences of the ends of the two rotating sleeves that are away from each other. Limit pins are inserted into the pin holes at both ends of the wire-paying shaft. The two rotating sleeves are respectively inserted into the two ends of the mounting through-hole in the middle of the enameled wire coil. The retaining rings limit the ends of the enameled wire coil. The enameled wire coil can rotate relative to the wire-paying shaft along with the rotating sleeves, thereby achieving smooth release of the enameled wire on the enameled wire coil. The limit pins limit the outer side of the retaining ring to prevent the rotating sleeve and the retaining ring from separating from the ends of the mounting through-hole in the middle of the enameled wire coil.

[0011] Furthermore, the lifting wire-paying mechanism further includes a latch and a pinhole. The latch is inserted into the socket in the middle of each longitudinal beam, and the side of the shaft support is provided with a pinhole that corresponds to the latch. After the hydraulic cylinder is raised to support the pay-off shaft and enameled wire coil, the latch engages with the pinhole on the side of the shaft support to limit the height of the shaft support, preventing the hydraulic cylinder from depressurizing and lowering. This allows the shaft support to no longer rely on the support of the hydraulic cylinder.

[0012] Furthermore, the hydraulic control mechanism includes a mounting bracket, a manual hydraulic pump, and hydraulic lines. The manual hydraulic pump is mounted on the top of the side frame via the mounting bracket, and the manual hydraulic pump is connected to the two hydraulic cylinders via hydraulic lines. The mounting bracket is used to mount the manual hydraulic pump, which controls the raising and lowering of the two hydraulic cylinders via hydraulic lines.

[0013] Furthermore, the pay-off resistance adding mechanism includes a fixed sleeve, a fixing screw, a longitudinal rod, a shift block and a friction rubber belt. A fixed sleeve is fixedly connected to the middle of the upper horizontal connecting beam, and the rear end of the longitudinal rod is inserted into the fixed sleeve. The top of the fixed sleeve is threadedly connected to a fixing screw, which presses against the longitudinal rod. The front end of the longitudinal rod cooperates with the circular hole on the shift block. A locking bolt is threadedly connected to the shift block, which presses against the longitudinal rod. The bottom of the shift block is connected to the top of the friction rubber belt. The fixed sleeve and the fixing screw cooperate to fix the rear end of the longitudinal rod. By loosening the locking bolt, the shift block can change its position along the longitudinal rod, thereby adjusting the position of the friction rubber belt. The friction rubber belt is placed on the front side of the enameled wire coil, and the friction with the enameled wire coil prevents the enameled wire coil from rotating excessively and uncontrollably.

[0014] Furthermore, the pay-off resistance adding mechanism further includes a connecting sleeve and a counterweight rod. The connecting sleeve is provided at the bottom end of the friction rubber belt, and the counterweight rod is inserted into the connecting sleeve. The connecting sleeve is used to secure the counterweight rod to the bottom of the friction rubber belt, ensuring that the friction rubber belt can maintain stable friction with the enameled wire coil.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the new enameled wire pay-off device has the following advantages:

[0016] 1. When the enameled wire coil needs to be placed on the lifting pay-off mechanism, the hydraulic control mechanism controls the lifting pay-off mechanism to lower its height. After the enameled wire coil is installed, the hydraulic control mechanism controls the lifting pay-off mechanism to rise, so that the bottom of the enameled wire coil leaves the ground, and then releases the wheel brake. With the help of the universal wheel, the pay-off frame composed of the side frame, longitudinal beam and transverse connecting beam is moved to the required position, and the enameled wire coil is conveniently moved up and down the pay-off shaft.

[0017] 2. A hydraulic cylinder is provided. After the rotating shaft passes through the installation hole in the middle of the enameled wire coil, it can be lifted off the ground with the help of the hydraulic cylinder, and then moved to the required position through the universal wheel. There is no need to use a forklift, and the wire is released smoothly, which brings great convenience to employees' work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] For example 1, please refer to Figures 1 to 3 , the utility model provides a technical solution: a novel enameled wire pay-off device, comprising an enameled wire supporting and moving mechanism 1, a lifting pay-off mechanism 2 and a pay-off resistance adding mechanism 4;

[0024] The enameled wire supporting and moving mechanism 1 includes a side frame 11, a longitudinal beam 12, a transverse connecting beam 13, a universal wheel 14 and a wheel brake 15. There are two side frames 11, and the upper and lower ends of the rear sides of the two side frames 11 are fixedly connected by the transverse connecting beam 13. The bottom of each side frame 11 is fixedly connected to the longitudinal beam 12, and the front and rear sides of the bottom of each side frame 11 are respectively installed with a universal wheel 14, and the universal wheel 14 is installed with a wheel brake 15;

[0025] The lifting pay-off mechanism 2 is installed between the bottoms of the two side frames 11, and the lifting pay-off mechanism 2 is connected to the hydraulic control mechanism 3;

[0026] The lifting wire-paying mechanism 2 includes a support block 21, a mounting sleeve 22, a hydraulic cylinder 23, a rotating shaft support 24, and a wire-paying rotating shaft 25. The support blocks 21 are fixedly connected to the sides of the bottom centers of the two side frames 11 that are close to each other. The top of each support block 21 is fixedly connected to the bottom end of the hydraulic cylinder 23 through the mounting sleeve 22. The top of each hydraulic cylinder 23 is fixedly connected to the rotating shaft support 24. Each rotating shaft support 24 is provided with a limiting groove. The two ends of the wire-paying rotating shaft 25 are respectively overlapped in the limiting grooves on the two rotating shaft supports 24. The support block 21 and the mounting sleeve 22 are used to install the hydraulic cylinder 23. The lifting of the hydraulic cylinder 23 can drive the rotating shaft support 24 to lift and lower, thereby driving the wire-paying rotating shaft 25 to lift and lower. Since the wire-paying rotating shaft 25 is inserted into the mounting through hole in the middle of the enameled wire coil 5, it is convenient to drive the enameled wire coil 5 to lift and lower as needed, thereby realizing the easy lifting and lowering of the wire-paying rotating shaft 25 of the enameled wire coil 5.

[0027] The lifting wire-releasing mechanism 2 further includes a rotating sleeve 26, a retaining ring 27, and a limiting pin 28. Two rotating sleeves 26 are rotatably sleeved on the wire-releasing shaft 25. The outer peripheral sides of the two rotating sleeves 26, which are away from each other, are fixedly connected to retaining rings 27. The limiting pins 28 are inserted into the pin holes at both ends of the wire-releasing shaft 25. The two rotating sleeves 26 are respectively inserted into the two ends of the mounting hole in the middle of the enameled wire coil 5. The retaining ring 27 limits the two ends of the enameled wire coil 5. The enameled wire coil 5 can rotate relative to the wire-releasing shaft 25 along with the rotating sleeve 26, thereby achieving a smooth release of the enameled wire on the enameled wire coil 5. The limiting pin 28 limits the outer side of the retaining ring 27 to prevent the rotating sleeve 26 and the retaining ring 27 from detaching from the end of the mounting hole in the middle of the enameled wire coil 5.

[0028] The lifting wire-paying mechanism 2 further includes a latch 29 and a pin hole 210. The latch 29 is inserted into the socket in the middle of each longitudinal beam 12, and the side of the shaft support 24 is provided with a pin hole 210 that corresponds to the latch 29. After the hydraulic cylinder 23 rises to support the wire-paying shaft 25 and the enameled wire reel 5, in order to prevent the hydraulic cylinder 23 from depressurizing and dropping, the latch 29 cooperates with the pin hole 210 on the side of the shaft support 24 to limit the height of the shaft support 24, so that the shaft support 24 no longer relies on the support of the hydraulic cylinder 23.

[0029] The hydraulic control mechanism 3 includes a mounting bracket 31, a manual hydraulic pump 32, and hydraulic lines 33. The manual hydraulic pump 32 is mounted on the top of the side frame 11 via the mounting bracket 31. The manual hydraulic pump 32 is connected to the two hydraulic cylinders 23 via hydraulic lines 33. The mounting bracket 31 is used to mount the manual hydraulic pump 32, which controls the extension and retraction of the two hydraulic cylinders 23 via hydraulic lines 33. The manual hydraulic pump 32 controls the extension and retraction of the hydraulic cylinders 23 using existing technology.

[0030] The line-releasing resistance adding mechanism 4 is installed in the middle of the upper horizontal connecting beam 13 .

[0031] During use, when the enameled wire roll 5 needs to be placed on the lifting wire-paying mechanism 2, the hydraulic control mechanism 3 controls the lifting wire-paying mechanism 2 to lower its height. After the enameled wire roll 5 is installed, the hydraulic control mechanism 3 controls the lifting wire-paying mechanism 2 to rise, so that the bottom of the enameled wire roll 5 leaves the ground, and then releases the wheel brake 15. With the help of the universal wheel 14, the wire-paying frame composed of the side frame 11, the longitudinal beam 12 and the transverse connecting beam 13 is moved to the required position, and then the universal wheel 14 is locked with the help of the wheel brake 15. Then the enameled wire on the enameled wire roll 5 is paid out, and the wire-paying resistance adding mechanism 4 is placed on the front side of the enameled wire roll 5. The friction between the enameled wire roll 5 and the wire-paying resistance adding mechanism 4 prevents the enameled wire roll 5 from rotating excessively due to excessive tension on the enameled wire, ensuring that the enameled wire on the enameled wire roll 5 is released stably.

[0032] For example 2, please refer to Figures 1 to 3 , the utility model provides a technical solution: a new type of enameled wire pay-off device, this embodiment is a further explanation of the structure of embodiment 1;

[0033] The line-releasing resistance adding mechanism 4 includes a fixed sleeve 41, a fixing screw 42, a longitudinal rod 43, a shift block 44 and a friction rubber belt 45. The middle part of the upper horizontal connecting beam 13 is fixedly connected with the fixed sleeve 41, and the rear end of the longitudinal rod 43 is inserted into the fixed sleeve 41. The top of the fixed sleeve 41 is threadedly connected with the fixing screw 42, and the fixing screw 42 is pressed against the longitudinal rod 43. The front end of the longitudinal rod 43 cooperates with the circular hole on the shift block 44. The shift block 44 is threaded with a locking bolt, which is pressed against the longitudinal rod 43. The bottom of the shift block 44 is connected to the top of the friction rubber belt 45.

[0034] The pay-off resistance adding mechanism 4 further includes a connecting sleeve 46 and a counterweight rod 47. The connecting sleeve 46 is provided at the bottom end of the friction rubber belt 45, and the counterweight rod 47 is inserted into the connecting sleeve 46. The connecting sleeve 46 is used to fix the counterweight rod 47 to the bottom of the friction rubber belt 45, so that the friction rubber belt 45 can maintain stable friction with the enameled wire coil 5.

[0035] The fixing sleeve 41 and the fixing screw 42 cooperate to fix the rear end of the longitudinal rod 43. By loosening the locking bolt, the shift block 44 can change its position along the longitudinal rod 43, thereby adjusting the position of the friction rubber belt 45. The friction rubber belt 45 is placed on the front side of the enameled wire coil 5, and the friction with the enameled wire coil 5 prevents the enameled wire coil 5 from rotating excessively and uncontrolled.
