Description
Technical Field
[0001] The utility model relates to the technical field of weighing equipment, in particular to a high-precision ton bag packaging scale. Background Art
[0002] Ton bag packaging scale is usually used for large-capacity, fast and professional quantitative weighing and packaging of solid granular materials or powder materials. It is also a special equipment for large soft bag packaging. It is a multifunctional packaging machine integrating electronic weighing, automatic bag removal and dust removal. Ton bag packaging scale not only has a high degree of automation, but also has high packaging accuracy and adjustable packaging speed. Ton bag packaging machine is suitable for large bag packaging in cement, building materials, chemicals, pesticides, fertilizers, rubber, plastics, metallurgy, fertilizers, grain, energy minerals, medicine, food, lithium battery and other industries.
[0003] In the prior art, ton bag packaging scales generally use four linear shaft guides to achieve lifting and lowering. However, in actual use, the parallelism of this structure is poor in manufacturing and installation, which correspondingly affects the accuracy. In addition, there is metal friction between the guide shaft and the linear bearing, which will produce metal debris or powder, and cannot meet the on-site requirements of certain industries with high precision requirements. Utility Model Content
[0004] In view of the above problems, the purpose of the utility model is to provide a high-precision ton bag packaging scale, which has more stable and smooth lifting and higher weighing accuracy.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a high-precision ton bag packaging scale, comprising a lifting frame, which is mounted on a guide shaft and can be lifted and lowered along the guide shaft under the drive of a lifting cylinder, and a lifting auxiliary mechanism is installed at the position of the guide shaft of the lifting frame, and the lifting auxiliary mechanism has a guide wheel bracket, and a plurality of guide wheels are arranged in pairs on the guide wheel bracket, and each pair of guide wheels is respectively arranged on both sides of the guide shaft.
[0006] In the above technical solution, guide shafts are provided at the four corners of the lifting frame, and a lifting auxiliary mechanism is installed on each guide shaft.
[0007] In the above technical solution, a protective cover is provided on the outer side of the guide wheel bracket.
[0008] In the above technical solution, the guide wheel is made of non-metallic material.
[0009] In the above technical solution, a bearing is provided inside the guide wheel, and the guide wheel is mounted on the guide wheel frame through the bearing.
[0010] In the above technical solution, two pairs of guide wheels are provided on the guide wheel bracket, and the guide shaft is embedded between each pair of guide wheels.
[0011] To sum up, the technical solution of the utility model has the following beneficial effects compared with traditional technical means: the utility model sets a lifting auxiliary mechanism at the position of the guide shaft of the lifting frame, and the guide shaft of the lifting frame is embedded between the guide wheels on the lifting auxiliary mechanism. The two sides of the guide shaft are supported and guided, with higher load-bearing capacity, more reliable guide positioning, freer and smoother movement, no jamming, and greatly improved corresponding weighing accuracy.
