When battery foil rolls of different specifications need to be inspected, different unwinding machine cone heads need to be replaced. In order to facilitate unwinding inspection of battery foil rolls of different specifications, a universal unwinding machine cone head is needed, which can adapt to the steel sleeve or the expansion shaft at the same time, thereby generating the present case. Utility Model Content

[0003] The utility model aims to provide a universal uncoiler cone head and an uncoiler, so as to overcome the problem that the uncoiler cone head needs to be replaced when replacing battery foil rolls of different specifications.

[0006] A snap-in groove is formed at one end of the cone head body facing away from the winding machine for the expansion shaft end to be embedded in. The expansion shaft end is cylindrical, and an inner annular tooth is formed on its cylindrical inner wall. The inner annular tooth is arranged in a circumferential ring direction, and an outer annular tooth that cooperates with the inner annular tooth is formed in the center of the snap-in groove. When the expansion shaft end is embedded in the snap-in groove, the outer annular tooth is located in the expansion shaft and meshes with the inner annular tooth.

[0007] Furthermore, the clamping groove extends along its axial direction to form a pin shaft, the pin shaft is arranged on the side away from the winding machine, and a slot is formed in the end of the expansion shaft along the axial direction, so that when the expansion shaft is embedded in the clamping groove, the pin shaft is inserted into the slot.

[0008] Furthermore, a clamping groove is formed on the bottom wall of the clamping groove, and a clamping protrusion cooperating with the clamping groove is formed on the outer ring tooth. The clamping protrusion is inserted into the clamping groove, so that when the cone head body rotates around the axis, the outer ring tooth drives the expansion shaft to rotate.

[0009] Furthermore, the card slot is a cross-shaped structure, and the card protrusion is also a cross-shaped structure.

[0010] Furthermore, it also includes a wear-resistant sheet, which is an annular structure, and its outer contour is consistent with the inner contour of the clamping groove, and is embedded in the clamping groove, so that when the expansion shaft is embedded in the clamping groove, it abuts against the cylindrical outer peripheral side of the expansion shaft.

[0011] Furthermore, it also includes a stop key, which is fixedly arranged on the outer circumference of the cone head body, and a sleeve insertion hole is formed on the outer edge of the end of the steel sleeve, so that when the cone head body is inserted into the steel sleeve, the stop key is inserted into the sleeve insertion hole and extends radially out of the steel sleeve.

[0012] The utility model also provides an uncoiler, which uses the above-mentioned universal uncoiler cone head, including an uncoiler module, a cone head body fixed at one end of the uncoiler module, two uncoiler modules, and is symmetrically arranged on the left and right, the cone head body is located on the inner side, and the two cone head bodies are arranged opposite to each other.

The driving device is linearly slidably arranged on the top side of the machine base to drive the cone head body to approach or move away from the steel sleeve, or drive the cone head body to approach or move away from the expansion shaft.

[0015] After adopting the above scheme, the beneficial effects of the utility model are:

[0016] The outer contour of the cone head body of the utility model is conical, which can be inserted into the steel sleeve and pressed against the inner wall of the steel sleeve to cooperate with the steel sleeve. When the cone head body rotates around the axis with the uncoiler shaft, it can drive the steel sleeve to rotate at the same time to unwind the battery foil roll; in addition, a clamping groove is formed at one end of the cone head body away from the unwinder for the end of the expansion shaft to be embedded. Since the end of the expansion shaft is cylindrical and an inner annular tooth is formed on the inner wall of the cylinder, and an outer annular tooth cooperating with the inner annular tooth is protruded in the center of the clamping groove, when the end of the expansion shaft is embedded in the clamping groove, the outer annular tooth is located in the expansion shaft and meshes with the inner annular tooth. When the cone head body rotates around the axis with the uncoiler shaft, it can drive the expansion shaft to rotate to unwind the battery foil roll; the cone head body can be adapted to the steel sleeve or the expansion shaft at the same time. When replacing battery foil rolls of different specifications, there is no need to replace the cone head body, which is more convenient to use and can improve the detection efficiency.

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the claims, specification and the above-mentioned drawings of the utility model, unless otherwise explicitly defined, directional words, such as the use of terms such as "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the specific protection scope of the utility model.

[0031] The utility model provides a universal uncoiler cone head, such as Figures 1 to 4 As shown, it includes a cone head body 1; one end of the cone head body 1 is fixedly connected to the rotating shaft 3 of the uncoiler 2, and the end away from the coiler 2 is used to connect with the expansion shaft 7 or the steel sleeve 5, so that when the rotating shaft 3 rotates around the axis, the cone head body 1 can drive the expansion shaft 7 or the steel sleeve 5 to rotate, so as to realize winding or unwinding, which is convenient for detecting the number of pinholes in the battery foil and the oil content on the surface of the battery foil; specifically, the battery foil roll 100 is wound on the expansion shaft 7, or on the steel sleeve 5, and the expansion shaft 7 can be an expansion shaft with different diameters but the same end structure. According to different specifications of battery foil rolls 100, they are correspondingly wound on expansion shafts 7 of different specifications and sizes, or on the steel sleeve 5.

[0032] The end where the cone head body 1 and the uncoiler 2 are fixed forms a shaft socket 301, which is consistent with the outer contour of the shaft 3. A keyway is also formed in the shaft socket 21 along the axial direction, so that when the shaft 3 is inserted into the shaft socket 301, it is clamped with the cone head body 1. The cone head body 1 can rotate around the axis with the shaft 3 to avoid idling. Of course, in other embodiments, other connection methods are also possible, not limited to this. In addition, in order to avoid shaking when the shaft 3 drives the cone head body 1 to rotate around the axis, the central axis of the shaft 3 coincides with the central axis of the cone head body 1.

[0033] In this specific embodiment, the outer contour of the cone head body 1 is retracted inwardly toward the direction away from the winding machine 2 to form a cone 4, which is used to be inserted into the steel sleeve 5 and pressed against the inner wall of the steel sleeve 5; in order to avoid the steel sleeve 5 from idling and slipping when the rotating shaft 3 drives the cone head body 1 to drive the steel sleeve 5 to rotate, as shown in FIG. Fig. 9 As shown, it also includes a stop key 16, which is fixedly arranged on the outer periphery of the cone head body 1. Fig.10 As shown, a sleeve insertion hole 17 is formed on the outer edge of the end of the steel sleeve 5, so that when the cone head body 1 is inserted into the steel sleeve 5, the stop key 16 is inserted into the sleeve insertion hole 17 and extends radially out of the steel sleeve 5, so that a clamping connection is formed between the cone head body 1 and the steel sleeve 5, and no idling occurs. In addition, a bolt hole 24 is formed on the cone head body 1, and also includes a bolt 25. The stop key 16 passes through a through hole, and the bolt 25 passes through the through hole and is screwed to the bolt hole 24 to fix the stop key 16 to the cone head body 1. Of course, in other embodiments, other fixing methods can also be used.

[0034] In this specific embodiment, Figure 6 As shown, the end of the cone head body 1 away from the winding machine 2 is formed with a clamping groove 6 for the end of the expansion shaft 7 to be inserted. Figure 7 As shown, the end of the expansion shaft 7 is hollow and cylindrical, and an inner ring gear 9 is formed on the inner wall of the cylinder. The inner ring gear 9 is arranged in a circumferential ring direction, as shown in FIG. Figure 1As shown, the center of the clamping groove 6 is protruded to form an outer ring tooth 10 that cooperates with the inner ring tooth 9, so that when the end of the expansion shaft 7 is inserted into the clamping groove 6, the outer ring tooth 10 is located in the expansion shaft 7 and meshes with the inner ring tooth 9 (as shown in FIG. Figure 8 Similarly, in order to prevent the expansion shaft 7 from shaking when the rotating shaft 3 drives the cone head body 1 to rotate around the axis, the central axis of the expansion shaft 7 coincides with the central axis of the cone head body 1.

[0035] In this specific embodiment, in order to ensure that the cone head body 1 does not idle when the rotating shaft 3 drives the cone head body 1 to rotate around the axis, as shown in FIG. Figure 1 As shown, a clamping groove 13 is formed on the bottom wall of the clamping groove 6, and a clamping protrusion 14 that cooperates with the clamping groove 13 is formed on the outer annular tooth 10. Figure 4 As shown, the clamping protrusion 14 is inserted into the clamping groove 13, so that when the cone head body 1 rotates around the axis, the outer annular tooth 10 drives the expansion shaft 7 to rotate. In addition, the outer annular tooth 10 is fixed to the clamping groove 6 of the cone head body 1 by screws. Of course, it can also be integrally formed or fixed in other ways, without limitation to this.

[0036] Furthermore, the slot 13 is a cross-shaped structure, and the cam 14 is also a cross-shaped structure. The setting of the cross-shaped structure enables the outer ring gear 10 to more stably transmit the torque of the rotating shaft 3 to the expansion shaft 7. Of course, in other embodiments, the slot 13 can also be a cross-shaped structure, etc., and is not limited to this. Those skilled in the art can design it according to the specific situation.

[0037] In this specific embodiment, when the battery foil roll 100 is unwinding, when the unwinding speed is high, in order to prevent the expansion shaft 7 from being thrown out by the high-speed rotating unwinding machine 8, the clamping groove 6 extends along its axial direction to form a pin shaft 11, and the pin shaft 11 is arranged on the side away from the unwinding machine 2. The cylindrical bottom wall of the expansion shaft 7 is formed with a slot 12 for the pin shaft 11 to be inserted. Figure 8 As shown, when the expansion shaft 7 is embedded in the clamping groove 6, the pin shaft 11 is inserted into the slot 12, which can effectively reduce the deflection of the expansion shaft 7 when it rotates and prevent the expansion shaft 7 from being thrown out.

[0038] In this specific embodiment, since different battery foil rolls are tested during the detection process, the expansion shaft 7 needs to be replaced frequently. In order to avoid the wear of the cone head body 1, a gap is easily formed between the expansion shaft 7 and the clamping groove 6, so that the expansion shaft 7 is prone to shake during the unwinding process. In order to avoid the wear in the clamping groove 6 caused by frequent replacement of the expansion shaft 7 and reduce the service life of the cone head body 1, a wear-resistant sheet 15 is also included. The wear-resistant sheet 15 is an annular structure, and its outer contour is consistent with the inner contour of the clamping groove 6, and is embedded in the clamping groove 6. When the expansion shaft 7 is embedded in the clamping groove 6, it abuts against the cylindrical outer peripheral side of the expansion shaft 7, which can effectively reduce the wear of the clamping groove 6 of the cone head body 1 and extend the service life. When the wear of the wear-resistant sheet 15 exceeds the allowable range, the wear-resistant sheet 15 can be replaced separately to reduce the cost of use.

[0039] Furthermore, in order to facilitate the installation and replacement of the wear-resistant sheet 15, an end cover 23 is also provided on the end face of the snap-in groove 6, so that when the wear-resistant sheet 15 is embedded in the snap-in groove 6, the end cover 23 is embedded in the end face of the snap-in groove 6 and fixed by screws.

[0040] The utility model also provides a decoiler 2, such as Figures 5 to 10 As shown, the above-mentioned machine cone head body 1 is applied, including an unwinding module 8, and the cone head body 1 is fixed at one end of the unwinding module 8. There are two unwinding modules 8, which are symmetrically arranged on the left and right. The cone head body 1 is located on the inner side, and the two cone head bodies 1 are arranged opposite to each other.

[0041] Specifically, the unwinding module 8 includes a driving device 18, a machine base 19 and a linear module 20; the linear module 20 includes a slider 21 and a slide rail 22, the slide rail 22 is fixed on the top side of the machine base 19, the slider 21 is fixed on the bottom side of the driving device 18, the slider 21 slides linearly along the slide rail 22, so that the driving device 18 slides linearly on the top side of the machine base 19; the rotating shaft 3 is set on the driving device 18, and the driving device 18 is used to drive the rotating shaft 3 to drive the cone head body 1 to rotate around the axis. When the linear module 20 drives the driving device 18 to slide linearly relative to the machine base 19, it drives the cone head body 1 to approach or move away from the steel sleeve 5, or drives the cone head body 1 to approach or move away from the expansion shaft 7.

[0042] By setting the linear module 20, the expansion shaft 7 or the steel sleeve 5 can be conveniently clamped or loosened, which is convenient for winding and unwinding the battery foil roll 5. At the same time, it is convenient to replace different expansion shafts 7 or replace the steel sleeve 5, which is easy to use.

[0043] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
