Description

Technical Field

[0001] The utility model relates to the technical field of corrugated roller equipment, in particular to a gear clearance adjustment device for double-layer corrugated paper wave to wave. Background Art

[0002] As the most important and widely used packaging material, corrugated cardboard has the advantages of light weight, low cost, easy processing, convenient storage and transportation, which are not possessed by wood packaging and metal packaging. It has high mechanical strength and can withstand collisions and falls during transportation. It is a necessary material for modern packaging.

[0003] For the corrugated board structure formed by four layers of corrugated paper (see Fig. 9 ), the inner core structure of this corrugated board requires two wavy boards to be bonded in a "wave-to-wave" form. This bonding method has high requirements for the teeth of the two corrugated rollers. If there is a slight misalignment, the "wave-to-wave" of the two wavy boards will have a large deviation. The two corrugated rollers rotate synchronously, and the teeth between the two corrugated rollers are relative. There will be a gear meshing gap between the gears meshing at the front ends of the two corrugated rollers. For this reason, we propose a gear gap adjustment device for double-layer corrugated paper wave-to-wave. Utility Model Content

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See attached Figure 1-9 A double-layer corrugated paper wave-to-wave gear clearance adjustment device includes a pair of adjusting gear assemblies symmetrically installed at both ends of a corrugated roller, and the corrugated roller equipped with the adjusting gear assembly is meshed with the gear of another corrugated roller equipped with a matching gear to produce a "wave-to-wave" double-layer corrugated paper structure. It can be understood that "wave-to-wave" refers to the corresponding bonding between the wave crests and wave crests, and the wave troughs and wave troughs between two wavy corrugated papers; it is formed by meshing and transmitting a wavy corrugated paper on each corrugated roller, the two corrugated rollers rotate synchronously, and the teeth between the two corrugated rollers are relative.

[0035] The adjusting gear assembly comprises a main gear 1 which is key-connected and mounted on the corrugated roller, and a sub-gear 2 is fitted on one side of the main gear 1, and the main gear 1 and the sub-gear 2 have the same gear parameters;

[0036] The main gear 1 is provided with a plurality of assembly holes, and the auxiliary gear 2 is provided with a plurality of matching arc-shaped assembly grooves 2.1. The bolts first pass through the arc-shaped assembly grooves 2.1 on the auxiliary gear 2, and then are threadedly connected with the assembly holes on the main gear 1, that is, the main gear 1 and the auxiliary gear 2 can rotate relative to each other.

[0037] It is understandable that if Figure 3 As described above, there are four pairs of assembly holes and arc-shaped assembly grooves 2.1 in total, and they are arranged at intervals around the central axis of the corrugated roller, and each arc-shaped assembly groove 2.1 is cocentric to prevent the secondary gear 2 from being unable to rotate.

[0038] A pair of adjusting columns 3 are installed on the main gear 1 and are arranged with the axis of the corrugated roller as a dividing line, and a receiving groove for receiving the adjusting columns 3 is opened on the back of the auxiliary gear 2.

[0039] The adjusting column 3 comprises a column body 3.1 and a pair of split adjusting blocks 3.2. The two adjusting blocks 3.2 are symmetrically fitted at both ends of the column body 3.1. The fitting surfaces between the column body 3.1 and each adjusting block 3.2 are relatively inclined and can slide relative to each other.

[0040] The relative tilt setting means that in the cross-section state, the fitting surface intersects with the central axis of the column 3.1.

[0041] A pair of adjusting bolt groups 4 are also threadedly connected to the auxiliary gear 2 and respectively cooperate with a pair of adjusting columns 3. Each adjusting bolt group 4 includes two adjusting bolts, which pass through the auxiliary gear 2 and respectively conflict with the adjusting block 3.2. Figure 4 As described above, when it is necessary to adjust the angle of the corresponding teeth of the main gear 1 and the auxiliary gear 2, first screw the A bolt in an adjusting bolt group 4 so that the A bolt and its corresponding adjusting block 3.2 do not contact each other, then screw the B bolt in the same group in the opposite direction, and push the corresponding adjusting block 3.2 to push the adjusting column 3 to move in the direction of the A bolt, and the adjusting block 3.2 corresponding to the A bolt slides along the fitting surface, and synchronously, screw the A' bolt in another adjusting bolt group 4 in the same way so that the A' bolt and its corresponding adjusting block 3.2 do not contact each other, and then screw the B' bolt in the same group in the opposite direction so that the main gear 1 and the auxiliary gear 2 rotate relative to each other.
