Detailed implementation manners
[0041] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.
[0042] It should be noted that in the present utility model, the up, down, left, and right in the figure are regarded as the up, down, left, and right of the dynamic deviation rectifying and reverse pressure roller device of the foil winding machine described in this specification.
[0043] Now refer to the accompanying drawings to introduce the exemplary implementation manners of the present utility model. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present utility model in detail and completely, and to fully convey the scope of the present utility model to those skilled in the art. The terms in the exemplary implementation manners shown in the accompanying drawings are not limitations to the present utility model. In the drawings, the same unit / element uses the same reference numeral.
[0044] Unless otherwise specified, the terms (including scientific and technical terms) used herein have the ordinary meaning understood by those skilled in the art. In addition, it can be understood that the terms defined in the commonly used dictionary should be understood to have the same meaning as the context of their related fields, and should not be understood as idealized or overly formal meanings.
[0045] Please refer to Figure 1 , this implementation manner relates to a dynamic deviation rectifying and reverse pressure roller device of a foil winding machine, which is suitable for deviation rectifying and reverse pressure of the foil tape 6. The dynamic deviation rectifying and reverse pressure roller device of the foil winding machine includes a reverse pressure roller mechanism and an electric cylinder 9.
[0046] Among them, the reverse pressure roller mechanism at least has a fixed shaft 11, and a roller 13 is sleeved on the fixed shaft 11. The roller 13 can rotate around its own axis and can lift in a direction perpendicular to its own axis to convey the foil tape 6.
[0047] The roller 13 presses on the upper surface of the foil tape 6. As the roller 13 rolls, the foil tape 6 has a U-shaped bending tendency, asFigure 4 As shown, the roller 13 can also be referred to as a counter-pressure roller.
[0048] In some embodiments, there are two rollers 13, and the two rollers 13 are arranged parallel to each other vertically.
[0049] Among them, the push rod of the electric cylinder 9 is connected to the roller 13 in parallel. The electric cylinder 9 can push the roller 13 to reciprocate along the fixed shaft 11, so that the roller 13 corrects the deviation and applies counter-pressure to the foil strip 6. Parallel connection means that the push rod is parallel to the roller 13, and at the same time, the push rod and the roller 13 remain connected.
[0050] When winding the coil, the foil strip 6 moves left and right in the axial direction of the roller 13. In order to make the end face of the wound coil neat, at this time, the roller 13 will hinder the movement of the foil strip 6, generate resistance to the deviation correction of the foil strip 6, and is not conducive to the winding of the coil. To solve this problem, the electric cylinder 9 is used to push the roller 13 to reciprocate along the axial direction, and at the same time, it does not limit its rotation, so as to achieve the purpose of correcting the deviation and applying counter-pressure to the foil strip 6.
[0051] Specifically, please continue to refer to Figure 1 , the reverse pressure roller mechanism includes a support, a screw jack 2, an electric cylinder 9, a rotating shaft 4 and a motor 7.
[0052] As Figure 1 shown, the support is composed of a left support 1 and a right support 8.
[0053] A screw jack 2 is installed on both the left support 1 and the right support 8. The screw nuts of the two screw jacks 2 are both installed with pressure roller brackets, namely a left pressure roller bracket 14 and a right pressure roller bracket 10. The fixed shaft 11 is fixedly installed between the left pressure roller bracket 14 and the right pressure roller bracket 10, and the number of the fixed shafts 11 is the same as the number of the rollers 13.
[0054] Both ends of the fixed shaft 11 are fixed between the left pressure roller bracket 14 and the right pressure roller bracket 10, playing a role in supporting the roller 13.
[0055] The electric cylinder 9 is installed on the left pressure roller bracket 14 or the right pressure roller bracket 10.
[0056] In some embodiments, as Figure 1 or Figure 2 shown, the electric cylinder 9 is installed on the right pressure roller bracket 10.
[0057] Both shaft ends of the rotating shaft 4 are connected to the two screw jacks 2 through the first coupling 3 respectively. That is, the rotating shaft 4 connects the two screw jacks 2 in series to ensure that the two screw jacks 2 can act synchronously.
[0058] The output end of the motor 7 is connected to any one of the screw jacks 2 through the second coupling 5, so that the motor 7 drives the two screw jacks 2 to act synchronously, and the two screw jacks 2 drive the left pressure roller bracket 14, the right pressure roller bracket 10 and the roller 13 to lift synchronously.
[0059] When reverse pressure needs to be applied to the foil strip 6, the motor 7 is controlled to rotate, and through the second coupling 5, a pair of series-connected screw jacks 2 are driven to act synchronously, driving the left pressure roller bracket 14, the right pressure roller bracket 10 and the fixed shaft 11, the roller 13, and the electric cylinder 9 thereon to move up and down synchronously, bending the foil strip 6 tightened through the roller, and correcting the position of the foil strip 6.
[0060] As Figure 4 shown, when the metal foil strip advances, the roller 13 presses on the upper surface of the foil strip 6, and as the roller 13 rolls, the foil strip 6 has a tendency to bend in a U shape; at the same time, the roller 13 can move axially back and forth to correct the position of the foil strip passing through the surface, making the end face of the wound coil neat.
[0061] In some embodiments, in order to ensure that the roller 13 runs along a predetermined track and prevent deviation and shaking, linear guide rails 15 parallel to the screw are installed on both the left support 1 and the right support 8. At the same time, sliders are installed on both the left pressure roller bracket 14 and the right pressure roller bracket 10, and the sliders can slide along the linear guide rails 15.
[0062] The linear guide rails 15 cooperate with the sliders to guide the lifting of the roller 13.
[0063] Please refer to Figure 3 , at both ends inside the roller 13, first bearing seats 17 sleeved on the fixed shaft 11 are respectively provided.

[0064] That is, first deep groove ball bearings 16 are installed on the inner surfaces at both ends of the roller 13. The inner ring of the first deep groove ball bearing 16 is installed with a first bearing seat 17, and the inner ring of the first bearing seat 17 is installed with a linear bearing 18, and the linear bearing 18 is sleeved on the fixed shaft 11. Due to the existence of the first deep groove ball bearing 16 and the linear bearing 18, the roller 13 can rotate freely in the radial direction and can move left and right axially on the fixed shaft 11.
[0065] Please continue to refer to Figure 3 , the dynamic deviation correction reverse pressure roller device of the foil winding machine further includes a thrust arm 12, a second bearing seat 21, a bushing 23, an end cover 24 and a round nut 25.

[0067] The thrust arm 12 is sleeved on the fixed shaft 11, that is, the fixed shaft 11 passes through the central circular hole of the thrust arm 12. The push rod of the electric cylinder 9 is connected to the thrust arm 12 through a pin shaft 19 and a swivel joint 20. The thrust arm 12 does not contact the fixed shaft 11, that is, the inner diameter of the central circular hole of the thrust arm 12 is larger than the diameter of the fixed shaft 11.
[0068] Specifically, the push rod of the electric cylinder 9 is connected to one end of the swivel joint 20 through a pin shaft 19, and the other end of the swivel joint 20 is threadedly connected to the thrust arm 12. The thrust arm 12 is sleeved on the fixed shaft 11.
[0069] The second bearing seat 21 is sleeved and installed on the fixed shaft 11. The thrust arm 12 is connected to the second bearing seat 21. An angular contact ball bearing 22 is installed on the outer ring of the second bearing seat 21, and the outer ring of the angular contact ball bearing 22 contacts the inner wall of the roller 13.
[0070] Specifically, Figure 2 Taking the shown direction as a reference, the second bearing seat 21 is installed on the left end face of the thrust arm 12. A pair of angular contact ball bearings 22 are installed on the outer wall of the second bearing seat 21, and the outer rings of the angular contact ball bearings 22 contact the roller 13.

[0072] Specifically, continuing to take Figure 2 the shown direction as a reference, there is a bushing 23 on the left end face of the outer ring of the angular contact ball bearing 22, and an end cover 24 is installed on the right end face and on the end face of the roller 13 for axially pressing and fixing the angular contact ball bearing 22 to the roller 13. There are a pair of round nuts 25 on the right end face of the inner ring of the angular contact ball bearing 22 for pressing and fixing the angular contact ball bearing 22 to the second bearing seat 21. This series of parts enables the push rod of the electric cylinder 9 to drive the roller 13 to move axially back and forth.
[0073] The dynamic deviation rectifying and reverse pressure roller device of the foil winding machine further includes a guide seat 28 and a fixing pin 26.
[0074] Among them, the guide seat 28 is fixed to the left pressure roller bracket 14 or the right pressure roller bracket 10 where the electric cylinder 9 is located, and a strip-shaped groove is provided in the guide seat 28.

There is a strip-shaped groove in the guide seat 28, and the second deep groove ball bearing 27 can roll in the strip-shaped groove to limit the rotation of the thrust arm 12 around the fixed shaft 11.
