Description

Technical Field

[0001] This application relates to the technical field of copper sleeve winding machines, and in particular to a copper sleeve winding machine. Background Technology

[0002] A copper-shrouded heater is a heating element that uses a copper shroud as its basic structure and heat carrier. It generates heat through heating wires embedded in the copper shroud, achieving a rapid and uniform heating effect. In the production process of the heater's copper shroud, threaded grooves need to be machined on the outer surface of the copper shroud first. Then, the heating wire is pressed into and wound into the pre-machined grooves of the copper shroud using a copper shroud winding machine. The manufacturing process is completed through processes such as pressing and winding.

[0003] In related technologies, a copper sleeve winding machine includes a machine base, a support frame on the machine base, two feeding rollers rotatably connected between two opposite side walls of the support frame, and a feeding cavity for placing copper sleeves formed by the upper ends of the two feeding rollers. A pressing mechanism is slidably connected to the support frame, and the pressing mechanism is used to press the copper sleeves into the feeding cavity. The pressing mechanism includes a pressure roller and a fixed frame. The pressure roller is rotatably connected between two opposite side walls of the fixed frame. A hydraulic cylinder is provided on the fixed frame, and the hydraulic cylinder is used to drive the fixed frame to move towards or away from the machine base.

[0004] During the use of the copper sleeve winding machine, the operator needs to insert the heating wire into the feeding chamber to snap it into the groove of the copper sleeve. Since the fixing frame is located on the moving path of the heating wire into the feeding chamber, the fixing frame will interfere with the winding of the heating wire, affecting the working efficiency of the copper sleeve winding machine in winding the heating wire into the groove. Utility Model Content

[0005] In order to improve the interference of the pressing mechanism on the heating wire winding process, this application provides a copper sleeve winding machine.

[0006] This application provides a copper sleeve winding machine, which adopts the following technical solution: A copper sleeve winding machine includes a machine base with a support base. Two feeding rollers are rotatably connected to the support base. The upper ends of the two feeding rollers form feeding cavities for placing copper sleeves. The machine base is provided with a pressing mechanism for pressing the copper sleeves into the feeding cavities. The pressing mechanism includes a pressure roller and a fixed frame. The pressure roller is rotatably connected to the fixed frame. The fixed frame is provided with a lifting mechanism for driving the fixed frame to move towards or away from the machine base. The fixed frame is provided with a connecting seat for suspending and supporting the pressure roller above the two feeding rollers. When both the pressure roller and the feeding rollers are tangent to the copper sleeve, a gap is formed between the pressure roller and the two feeding rollers for a heating wire to extend into.

[0007] By adopting the above technical solution, the operator first places the copper sleeve in the feeding chamber, then snaps the end of the heating wire into the groove of the copper sleeve, and then presses the copper sleeve into the feeding chamber by the pressing mechanism. The rotation of the feeding roller drives the copper sleeve to rotate, so that the heating wire can be completely snapped into the groove of the copper sleeve, thereby realizing the pressing and winding of the heating wire. The gap between the pressure roller and the two feeding rollers allows the heating wire to extend in, avoiding the obstruction of the fixing frame on the path of the heating wire snapping and embedding into the groove, reducing the movement path of the heating wire snapping and embedding into the groove, and preventing the heating wire from shifting position due to the interference of obstacles, thereby improving the working efficiency of the copper sleeve pressing and winding machine.

[0008] Optionally, the connecting seat has a placement groove on its surface near the machine base for the pressure roller to pass through, and the cross-section of the placement groove along the width direction of the machine base is arc-shaped.

[0009] By adopting the above technical solution, the cross-section of the groove along the width of the machine is in the shape of an arc, which enables the groove to provide suspended support for the pressure roller. The groove wall is located on the moving path of the pressure roller close to the machine, thereby stably fixing the pressure roller in the groove. Furthermore, it provides operating space between the end face of the pressure roller and the feeding roller for the heating wire to extend into. By suspending the pressure roller, it reduces interference with the process of winding the heating wire around the copper sleeve.

[0010] Optionally, the machine base is provided with a fixed seat, and the fixed seat has two grooves. The two grooves are respectively used for placing the corresponding feeding rollers. The distance from the groove wall away from the other groove to the machine base is greater than the radius of the feeding roller.

[0011] By adopting the above technical solution, the distance from the groove wall away from another groove to the machine platform is greater than the radius of the feeding roller, which allows the groove to more stably limit the feeding roller, reducing the possibility of the feeding roller leaving the groove, further strengthening the obstruction of the groove wall on the feeding roller, thereby enhancing the overall stability of the copper sleeve winding machine.

[0012] Optionally, the fixed base has a connecting hole communicating with the groove, and a first roller is rotatably connected in the connecting hole. The first roller abuts against the outer surface of the feeding roller, and the first roller rotates in the same direction as the feeding roller.

[0013] By adopting the above technical solution, a first roller is rotatably connected in the connecting hole, and the first roller abuts against the outer surface of the feeding roller. This reduces the friction between the feeding roller and the groove wall, allowing the feeding roller to rotate more smoothly in the groove, while reducing the possibility of wear on the feeding roller and further extending its service life.

[0014] Optionally, the feeding roller is provided with a first gear, and the machine base is provided with a transmission mechanism. The transmission mechanism includes a gear seat, and a second gear is rotatably connected to the gear seat. The first gear and the second gear mesh with each other. The gear seat is provided with a power component, which is used to drive the second gear to rotate so as to realize the synchronous rotation of the two feeding rollers.

[0015] By adopting the above technical solution, the first gear and the second gear mesh with each other, so that the power component can drive the second gear to rotate to achieve synchronous rotation of the two feeding rollers, thereby allowing the copper sleeve to rotate stably on the two feeding rollers, and allowing the heating wire to be smoothly snapped into the groove of the copper sleeve.

[0016] Optionally, a locking block is provided on the inner surface of the first gear, and a locking groove is provided on the outer surface of the feeding roller, with the locking block engaging with the locking groove.

[0017] By adopting the above technical solution, the first gear can be fixed on the end face of the feeding roller through the snap-fit ​​of the clip and the slot, so that the first gear drives the feeding roller to rotate. This provides convenience for the workers to install or disassemble the first gear and the feeding roller. The workers can easily replace the first gear that has rusted or aged, thereby extending the overall service life of the equipment.

[0018] Optionally, the lifting mechanism includes a slide base and a threaded rod. The slide base has a threaded hole for inserting the threaded rod. The slide base is fixedly connected to the fixed frame. The threaded rod is used to drive the fixed frame to move towards or away from the material feeding roller.

[0019] By adopting the above technical solution, the operator can move the fixed frame closer to or further away from the feeding roller by rotating the threaded rod, thereby adjusting the distance between the pressure roller and the feeding roller to adapt to copper sleeves of different sizes, further enhancing the applicability of the copper sleeve winding machine. The operator can intuitively feel the degree of pressure of the pressure roller against the copper sleeve by rotating the threaded rod, reducing the possibility of the pressure roller excessively squeezing the copper sleeve and causing damage, so that the operator can better adjust the height of the pressure roller.

[0020] Optionally, the machine tool is provided with scale lines, which are distributed along the length of the machine tool, and the scale lines are used to compare the length of the product.

[0021] By adopting the above technical solution, the machine is equipped with scale lines, which makes it easy for staff to compare the length of the product. This reduces the steps that staff need to take to find measuring tools. Staff can directly compare the length of the product on the machine, thereby saving the time spent on length comparison and improving work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The operator first places the copper sleeve in the feeding chamber, then snaps the end of the heating wire into the groove of the copper sleeve. The clamping mechanism then presses the copper sleeve into the feeding chamber. The rotation of the feeding roller drives the copper sleeve to rotate, allowing the heating wire to be fully snapped into the groove of the copper sleeve, thus achieving the pressing and winding of the heating wire. A gap is formed between the pressure roller and the two feeding rollers for the heating wire to extend into, avoiding the obstruction of the fixing frame on the path of the heating wire snapping and embedding into the groove, reducing the movement path of the heating wire snapping and embedding into the groove, and preventing the heating wire from shifting position due to interference from obstacles, thereby improving the working efficiency of the copper sleeve pressing and winding machine.

[0023] 2. By placing the groove with an arc-shaped cross section along the width of the machine, the groove can provide suspended support for the pressure roller, allowing the groove wall to be located on the moving path of the pressure roller close to the machine, thereby stably fixing the pressure roller in the groove. Furthermore, it provides operating space between the end face of the pressure roller and the feeding roller for the heating wire to extend into, and by suspending the pressure roller, it reduces interference with the process of winding the heating wire around the copper sleeve.

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This embodiment discloses a copper sleeve winding machine. (Refer to...) Figure 1A copper sleeve winding machine includes a machine base 1. A support base 2 is fixedly connected to the surface of the machine base 1 away from the ground. The support base 2 has two support holes 23 for inserting the ends of corresponding feeding rollers 21. Feeding rollers 21 are rotatably connected to the support holes 23. The two feeding rollers 21 are horizontally distributed along the width direction of the machine base 1, and the upper ends of the two feeding rollers 21 enclose a feeding cavity 211 for placing copper sleeves.

[0028] Reference Figure 1 A fixed base 3 is fixedly connected to the surface of the machine base 1 away from the ground. The surface of the fixed base 3 away from the ground has a groove 31 for inserting and rotating a material feeding roller 21. Two grooves 31 are provided, symmetrically arranged along the axis of the fixed base 3. Each groove 31 is used to place the end of the corresponding material feeding roller 21 away from the support base 2, with the material feeding roller 21 extending to the side of the groove 31 away from the support base 2. The height of the groove wall of the groove 31 away from the other groove 31 is greater than the radius of the material feeding roller 21; that is, the cross-section of the groove 31 along the width direction of the fixed base 3 is an arc shape. The groove 31 can enclose more than half of the outer surface of the material feeding roller 21, reducing the possibility of the material feeding roller 21 detaching from the groove 31.

[0029] Reference Figure 1 and Figure 2 The fixed base 3 has two connecting holes 32, which are symmetrically arranged along the width of the fixed base 3. The connecting holes 32 extend through the fixed base 3 along its length and are connected to two grooves 31. Three first rollers 321 are rotatably connected in each connecting hole 32. The three first rollers 321 are arranged in an array along the length of the connecting hole 32. Each first roller 321 is tangent to the outer circumferential surface of the corresponding feeding roller 21, and the first rollers 321 rotate synchronously with the feeding roller 21.

[0030] Reference Figure 1 and Figure 2 A movable groove 311 is provided on the groove wall of the groove 31 away from the other groove 31. A second roller 312 is rotatably connected in the movable groove 311. The second roller 312 is tangent to the outer surface of the feeding roller 21. Both the first roller 321 and the second roller 312 are used to reduce the friction between the feeding roller 21 and the groove wall of the groove 31, which is conducive to the feeding roller 21 rotating more smoothly.

[0031] Reference Figure 1 and Figure 3 A first gear 22 is fixedly connected to the end face of the feeding roller 21 away from the fixed seat 3. A locking block 212 is fixedly connected to the outer surface of the feeding roller 21. A slot 221 for the locking block 212 to be inserted is opened on the inner surface of the first gear 22. The first gear 22 is fixed to the end face of the feeding roller 21 by the locking engagement of the locking block 212 and the slot 221.

[0032] Reference Figure 1 and Figure 3 The machine base 1 is equipped with a transmission mechanism, which includes a gear seat 4. The gear seat 4 is fixedly connected to the machine base 1 and is located on the side of the support base 2 away from the fixed base 3. A second gear 41 is rotatably connected to the surface of the gear seat 4 near the support base 2, and the first gear 22 meshes with the second gear 41. The second gear 41 is equipped with a power component 411, which is a motor. The power component 411 is used to drive the second gear 41 to rotate so that the two feeding rollers 21 rotate synchronously.

[0033] Reference Figure 1 The machine base 1 is equipped with a pressing mechanism 5 for pressing the copper sleeve into the feeding chamber 211. The pressing mechanism 5 includes a pressure roller 51 and a fixed frame 52. The pressure roller 51 is rotatably connected to the fixed frame 52, and the fixed frame 52 is slidably connected to the machine base 1. A lifting mechanism 15 is provided on the end face of the fixed frame 52 away from the machine base 1. The lifting mechanism 15 can drive the fixed frame 52 to move the pressure roller 51 towards or away from the machine base 1. A connecting seat 521 is fixedly connected to the surface of the fixed frame 52 near the machine base 1. The connecting seat 521 is used to suspend and support the pressure roller 51 directly above the two feeding rollers 21. When both the pressure roller 51 and the feeding rollers 21 are tangent to the outer surface of the copper sleeve, the copper sleeve is fixed in the feeding chamber 211. At this time, a gap is formed between the pressure roller 51 and the two feeding rollers 21 for the heating wire to extend into.

[0034] Reference Figure 1 The connecting seat 521 has a placement groove 522 on its surface near the fixed seat 3 for the pressure roller 51 to be inserted and rotated. The cross-section of the placement groove 522 along the width direction of the fixed frame 52 is arc-shaped. When the pressure roller 51 is inserted into the placement groove 522, the pressure roller 51 can be suspended directly above the feeding roller 21. The end face of the pressure roller 51 extends out of the placement groove 522 along its length direction. A gap is formed between the pressure roller 51 and the two feeding rollers 21 for the heating wire to extend into, so that the operator can insert the heating wire into the gap of the feeding cavity 211 so that the heating wire can be engaged and embedded in the groove on the surface of the copper sleeve.

[0035] Reference Figure 1 and Figure 4 The placement groove 522 has multiple receiving grooves 523 on its wall, which are symmetrically distributed circumferentially along the inner wall of the placement groove 522. A third roller 524 is rotatably connected inside the receiving groove 523. The third roller 524 abuts against the outer surface of the pressure roller 51. The third roller 524 is used to reduce the friction between the pressure roller 51 and the wall of the placement groove 522, so that the pressure roller 51 can rotate more smoothly.

[0036] Reference Figure 1A column plate 11 is fixedly connected to the surface of the machine base 1 away from the ground. A lifting mechanism 15 is slidably connected to the surface of the column plate 11 near the pressing mechanism 5. The lifting mechanism 15 includes a slide base 12 and a threaded rod 13. A threaded hole 121 for inserting the threaded rod 13 is opened on the surface of the slide base 12 away from the machine base 1. The slide base 12 is fixedly connected to the fixed frame 52. An operating wheel 131 is fixedly connected to the end face of the threaded rod 13 away from the fixed frame 52. The operator rotates the operating wheel 131 to drive the threaded rod 13 to move up and down, thereby adjusting the distance between the pressure roller 51 and the feeding roller 21.

[0037] Reference Figure 1 The machine 1 has scale lines 14 on its surface away from the ground. The scale lines 14 are arranged in an array along the length of the machine 1. The staff can intuitively compare the length of the product through the scale lines 14, which greatly facilitates the process of comparing the length of the product.

[0038] The implementation principle of a copper sleeve winding machine according to an embodiment of this application is as follows: The operator places the copper sleeve to be wound into the material placement cavity 211 between the pressure roller 51 and the two material placement rollers 21. Then, the operator adjusts the height of the pressure roller 51 by rotating the operating wheel 131 so that the pressure roller 51, the copper sleeve and the two material placement rollers 21 are in contact with each other and tangential. The operator inserts the end of the heating wire from the right side of the machine base 1 so that the heating wire can be snapped into the groove of the copper sleeve. Then, the pressing mechanism 5 presses the copper sleeve into the material placement groove. The power component 411 drives the two material placement rollers 21 to rotate the copper sleeve so that the heating wire is completely snapped into the groove of the copper sleeve, thereby completing the winding of the heating wire.
