DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] The following detailed description of embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application as claimed, but merely represents selected embodiments of the application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0032] Referring to Figures 1 to 4 As shown in the drawings, the present embodiment provides an aluminum foil paper lubricating device for lubricating the aluminum foil side of the oriented aluminum foil paper belt 1. Since the aluminum foil paper is a paper formed by bonding the aluminum foil lining paper with the aluminum foil paste, the aluminum foil only needs to be lubricated on one side. The device mainly comprises a lubricating roller 2, which is located on the conveying path of the aluminum foil paper belt 1 and is in rolling connection with the aluminum foil paper belt 1. The aluminum foil paper belt 1 is connected with the lubricating roller 2 in a U shape, so that the oil lubricant is evenly applied on the aluminum foil paper belt when the aluminum foil paper belt 1 rotates with the lubricating roller 2.

[0033] The lubricating roller 2 comprises a hollow outer cylinder 21, a connecting roller 22, an eccentric motion assembly and a plurality of planetary oil applying members. The hollow outer cylinder 21 is sealed at both ends. The eccentric motion assembly is used to drive the connecting roller 22 to make circumferential motion around the axis of the hollow outer cylinder 21 in the inner cavity of the hollow outer cylinder 21. The plurality of planetary oil applying members are arranged axially spaced apart along the hollow outer cylinder 21.

[0034] The planetary oil applying member comprises a cylinder barrel 23, a piston 24 and a connecting rod 25. The hollow outer cylinder 21 is embedded with a plurality of cylinder barrels 23 around the circumference. The cylinder barrel 23 communicates the outside and the inner cavity of the outer cylinder. The piston 24 is slidably arranged in the cylinder barrel 23. One end of the connecting rod 25 is hinged to the piston 24, and the other end of the connecting rod 25 is hinged to the connecting roller 22. When the connecting roller 22 rotates around the axis of the hollow outer cylinder 1, the plurality of connecting rods 25 drive the plurality of pistons 24 to make reciprocating motion in the corresponding cylinder barrels 23, which is similar to the oil cylinder and piston of a rotary engine.

[0035] More specifically, the cylinder barrel 23 has an oil inlet 231 penetratingly formed in the side wall. The oil inlet 231 communicates with the inner cavity of the hollow outer cylinder 21. The oil inlet 231 is located on the moving path of the piston 24. When the connecting roller 22 rotates to the side close to the axis of the hollow outer cylinder 21, the oil inlet 231 is not blocked by the piston 24 inside it.

[0036] The lubricating roller 2 has two, which are arranged symmetrically left and right. The aluminum foil paper belt 1 is connected with the lubricating roller 2 in a U shape with the opening upward, and the aluminum foil paper belt 1 is conveyed from the outer side to the inner side of the two lubricating rollers 2.

[0037] The cylinder barrel 23 whose oil inlet 231 is not blocked by the piston 24 always remains at the position where the lubricating roller 2 starts to contact the aluminum foil paper belt 1. As Figures 1-3 As shown in the drawings, in specific implementation, when the aluminum foil paper belt 1 is tangent to the lubricating roller 2, Figure OneWhen the hollow outer cylinder 21 rotates to the left side in the figure, the piston 24 in the cylinder barrel 23 moved to this position is driven by the connecting roller 22 to the end of the cylinder barrel 23 close to the axis of the hollow outer cylinder 21, at this time the oil inlet 231 of the cylinder barrel 23 is completely communicated with the inner cavity of the cylinder barrel 23, and the oil lubricant quickly enters and fills the entire cylinder barrel 23, and as it follows the hollow outer cylinder 21 to rotate downward to the other side and separates from the aluminum foil tape 1, the piston 24 in the inside continuously extrudes outward, and then extrudes the oil lubricant in the cylinder barrel 23 to the space between the hollow outer cylinder 21 and the aluminum foil tape 1, and the pasty oil lubricant is uniformly distributed on the aluminum foil tape 1. When the aluminum foil tape 1 separates from the hollow outer cylinder 21, the oil lubricant moves with the aluminum foil tape 1, and in this way, the oil lubricant in each cylinder barrel 23 on the hollow outer cylinder 21 is uniformly extruded onto the aluminum foil tape 1, which not only prevents the oil lubricant from scattering, but also uniformly and efficiently applies oil to the aluminum foil tape 1.

[0038] More specifically, as shown in Figure 3 The eccentric motion assembly includes a first transmission shaft 26, a second transmission shaft 27, and two eccentric wheels 28, the two eccentric wheels 28 are rotatably arranged at both ends of the inner cavity of the hollow outer cylinder 21, the shaft of the eccentric wheel 28 is coaxial with the hollow outer cylinder 21, and the shafts of the connecting rollers 22 on both sides are rotatably connected with the shafts of the two eccentric wheels 28;

[0040] More specifically, the second transmission shaft 27 is a hollow tube, the second transmission shaft 27 is arranged at one end of the hollow outer cylinder 21 and connected with the oil pipe 4 through the rotary joint 3; the second transmission shaft 27 is sleeved with the third gear 11, and the two third gears 11 are engaged with each other. By driving one third gear 11 to rotate through the second low-speed motor, the relative rotation of the two hollow outer cylinders 21 is realized, the aluminum foil paper belt 1 can be conveyed at the same time, the oil cylinder 23 at the position where the oil inlet 231 is communicated with the oil cylinder 23 is on the outside just in contact with the aluminum foil paper belt 1, and the piston 24 compresses the oil cylinder of the oil cylinder 23 to be separated from the aluminum foil paper belt 1. It needs to be noted that the hollow outer cylinder 21 continuously rotates, and the connecting roller 22 also rotates in the hollow outer cylinder 21, the two rotation directions are consistent, but the aluminum foil paper belt 1 is always kept in contact with the hollow outer cylinder 21, the oil inlet 231 at this position is just communicated with the oil cylinder 23, and then in the process of rotating for a half cycle, the oil lubricant can be continuously extruded. In the process of the aluminum foil paper belt 1 being separated from the contact, the piston moves from the bottom of the cylinder 23 in the axial direction, to the oil inlet 231 communicated with the oil cylinder 23, and the next oil extrusion is carried out.

[0041] More specifically, it further includes a rubber sleeve 29, the rubber sleeve 29 is sleeved on the hollow outer cylinder 21, a plurality of grid holes are formed on the surface of the rubber sleeve 29, and one grid hole is communicated with one cylinder 23. Then the aluminum foil paper belt 21 is wrapped on the rubber sleeve 29, so that each grid is in a sealed state, when the oil lubricant in the oil cylinder 23 is extruded, it is just filled in the grid, and it is moved away with the aluminum foil paper belt 1 being separated, which not only prevents the oil lubricant from overflowing, but also prevents the aluminum foil paper belt from being broken.

[0042] More specifically, it further includes two pressing rollers 5, the two pressing rollers 5 are horizontally and spaced apart, and the two aluminum foil paper belts 1 are output from between the two lubricating rollers 2 and then pass between the two pressing rollers 5. The two pressing rollers 5 are in abutment with the two aluminum foil paper belts 1 passing between the two pressing rollers 5, the two aluminum foil paper belts coated with oil lubricant are extruded by the two pressing rollers 5, and then the paste oil lubricant attached to the aluminum foil paper belt is uniformly and smoothly pressed and covered on the aluminum foil paper belt, and the uniform lubrication of the aluminum foil paper belt is further realized.

[0043] As shown in Figure 4 It further includes a rack 6, the lubricating roller 2 is rotatably arranged on the rack 6; two waist holes 61 are symmetrically formed on the rack 6, one pressing roller 5 is rotatably connected with the rack 6, and the rotating shafts at two ends of the other pressing roller 5 are respectively slidably arranged to pass through the two waist holes 61, a bearing seat is slidably arranged on the waist hole to prevent the pressing roller 5 from deviating, the two pressing rollers 5 are sleeved with the first gear 7 on the two sides, and the two first gears 7 on the two sides of the two pressing rollers 5 are engaged with each other.

[0044] The sliding sleeve 8 and the spring 9 are further included, the sliding sleeve 8 is rotatably sleeved on both sides of the compression roller 5, and the two sliding sleeves 8 on the two sides of the two compression rollers 5 are connected through the spring 9. In specific implementation, the two compression rollers 5 abut each other through the two springs 9 on the two sides, and then the two aluminum foil paper strips 1 are dynamically extruded through the elastic force of the spring 9 while keeping relative rotation, avoiding the fixed position of the traditional two compression rollers 5, and the difficulty in uniform oil lubrication when the aluminum foil paper strip is thick and thin.
