Description

Technical Field

[0001] This utility model is specifically a copper strip guide roller, which relates to the field of copper-aluminum composite strip production technology. Background Technology

[0002] Copper-aluminum composite materials combine the advantages of copper and aluminum, featuring high electrical conductivity, thermal conductivity, lightweight, corrosion resistance, and low overall cost. They are widely used in fields such as power, semiconductors, electronic devices, and power lithium batteries.

[0003] As attached Figure 1 As shown, in the field of power lithium batteries, copper-aluminum composite materials with copper and aluminum composites at both ends and aluminum in the middle are commonly used as the terminals of lithium batteries. In the process of preparing this copper-aluminum composite material, guide wheels are needed to guide the copper strips, and the spacing between the copper strips must be strictly controlled so that adjacent copper strips can enter the gap of the rolls at a fixed interval to combine with the aluminum liquid, forming a copper-aluminum composite strip that meets the size requirements of lithium battery terminals.

[0004] Patent CN218201322U discloses a guiding device for composite strip production. This patent uses a threaded adjustment to adjust the distance between two guide wheels, thereby achieving precise control over the distance between two copper strips. However, this patent has some shortcomings. For example, the threaded adjustment structure occupies a large length of the mounting shaft, preventing the installation of more guide wheels. Furthermore, axial clearance in the bearings within the guide wheels can also affect the spacing of the copper strips. Utility Model Content

[0006] The present invention adopts the following technical solution: A copper strip guide device for entering a roller includes a mounting frame, a mounting shaft, and a copper strip guide assembly mounted on the mounting shaft. The copper strip guide assembly mainly consists of an inner bushing, an outer bushing, a movable guide wheel, a round nut, and a bearing. The bearing is installed between the inner bushing and the outer bushing. A fixed guide wheel is provided on the outer bushing. The round nut and the movable guide wheel are screwed onto the outer bushing for adjusting the spacing of the copper strip.

[0007] Further improve the technical solution: square column structures are provided at both ends of the mounting shaft, and square groove structures that cooperate with the square column structures are provided on the mounting frame.

[0008] Further improve the technical solution: A set screw is screwed onto the inner bushing, which is used to fix the inner bushing onto the mounting shaft.

[0025] A copper strip guide roller is disclosed, relating to the field of copper-aluminum composite strip production technology, mainly to solve the problem of inadequate guide devices in the existing technology. The composition and working principle of this utility model are described in detail below.

[0026] See attached document Figure 2 The copper strip guide device of this utility model consists of a mounting frame 1, a mounting shaft 2, and multiple copper strip guide components 3 mounted on the mounting shaft 2. The function of the copper strip guide components 3 is to guide the copper strip through guide wheels and strictly control the spacing between the copper strips, so that two adjacent copper strips can enter the gap of the roll at a fixed interval to combine with the aluminum liquid and form a copper-aluminum composite strip that meets the size requirements of lithium battery terminals.

[0027] There are many models of lithium battery terminals, requiring the replacement of copper strips and copper strip guide assemblies 3 with different widths during production. To facilitate the replacement of the copper strip guide assembly 3, square column structures are provided at both ends of the mounting shaft 2, and square groove structures that mate with the square column structures are provided on the mounting bracket 1. When it is necessary to replace the copper strip guide assembly 3, simply lift the mounting shaft 2 from the mounting bracket 1, and then remove the copper strip guide assembly 3 from the mounting shaft 2.

[0028] See attached document Figure 3 The copper strip guide assembly 3 mainly consists of an inner bushing 3.1, an outer bushing 3.2, a movable guide wheel 3.4, a round nut 3.5, and a pair of bearings 3.3.

[0029] See attached document Figure 4 The inner bushing 3.1 can be fitted onto the mounting shaft 2 via a bore and shaft fit. Four set screws 3.6 are screwed onto the left side of the inner bushing 3.1 to secure it to the mounting shaft 2. Additionally, the inner bushing 3.1 is provided with a stepped shaft structure for positioning the inner rings of a pair of bearings 3.3.

[0030] See attached document Figure 5 A fixed guide wheel 3.21 for guiding the copper strip is integrally provided on the left side of the outer bushing 3.2. The guide wheel has grooves on both sides, and the width of the two grooves is slightly larger than the width of the copper strip. A small-diameter tube is coaxially provided on the right side of the outer bushing 3.2, and external threads 3.22 are machined on the tube.

[0031] See attached document Figure 6 The movable guide wheel 3.4 is used to guide another copper strip. Unlike the fixed guide wheel 3.21, the inner ring surface of the movable guide wheel 3.4 is machined with an internal thread 3.42, and the movable guide wheel 3.4 is screwed onto the external thread 3.22 of the outer bushing 3.2 through the internal thread 3.42.

[0032] To facilitate the rotation of the movable guide wheel 3.4 using tools such as hook wrenches, four slots 3.41 resembling round nuts are provided at the end of the movable guide wheel 3.4. The movable guide wheel 3.4 can be rotated by hooking the hook wrench into the slots 3.41.

[0033] See attached document Figure 7 Since the movable guide wheel 3.4 is screwed onto the outer bushing 3.2, the distance between the movable guide wheel 3.4 and the fixed guide wheel 3.21 can be adjusted by rotating the movable guide wheel 3.4, thereby achieving precise adjustment of the copper strip spacing L.

[0034] To prevent the threads from loosening, a round nut 3.5 is screwed onto the external thread 3.22 of the outer bushing 3.22. The function of the round nut 3.5 is to tighten the movable guide wheel 3.4 and prevent the threads between the movable guide wheel 3.4 and the outer bushing 3.2 from loosening.

[0035] The copper-aluminum composite strip is produced continuously, and prolonged operation can cause the copper strip guide assembly 3 to overheat, severely affecting the service life of the bearing 3.3. To dissipate heat and cool the copper strip guide assembly 3, a through-hole is provided along the axial direction of the mounting shaft 2, and a cooling medium is introduced into the cooling hole.

[0036] Compared to the previous technical solution, this copper strip feed roller guide device has at least the following advantages: 1. This copper strip entry roller guide device screws the movable guide wheel 3.4 onto the outer bushing 3.2. While achieving precise adjustment of the copper strip spacing L, it compresses the axial dimension of the copper strip guide assembly 3 as much as possible, reduces the length occupied by the mounting shaft 2, and allows the mounting shaft 2 to install more copper strip guide assemblies 3, thereby increasing the output of lithium battery terminals by several times.

[0037] 2. Since the movable guide wheel 3.4 is screwed onto the outer bushing 3.2, the movable guide wheel 3.4 and the fixed guide wheel 3.21 are an integral structure. Even if there is axial clearance in the bearing 3.3, it will not affect the spacing of the copper strip.

[0038] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
