Holding device

Abstract

The invention relates to a holding device comprising a mechanical clamping hand which is fixed on a rotation block. The rotation block is connected with a lower part of a palm. The upper part of the palm is connected with a slide rail. A guide wheel is arranged below the part of the slide rail close to the end of the mechanical hand. The guide wheel is positioned in a cam disk groove. Because the guide wheel is positioned in the cam disk groove, the guide wheel rolls and rotates along the groove curve track. The telescoping working track of the mechanical clamping hand is controlled by the groove curve track. During the process, a part of a big extension spring is not applied, and downtime maintenance and downtime for big extension spring replacement are not needed. Therefore, production cost is reduced, production efficiency is improved, and stability is improved.

Description

technical field [0001] The invention relates to the field of processing equipment such as beverage bottles, oil bottles, and medicine bottles, and in particular to a clamping device. Background technique [0002] In the production process of plastic bottles, blow molding machines are often used. Blow molding machines are usually divided into semi-automatic and fully automatic. The semi-automatic type requires manual preheating of the preheated preform during the preheating to blow molding step. Putting it into the blow mold, the labor efficiency is low, and the automatic blow molding machine can quickly complete this step through the operation of the clamping device, which greatly speeds up the production efficiency. [0003] Such as Figure 5 , 6 , 7. At present, the clamping device of the fully automatic blow molding machine is to install the roller 14 at the bottom of the swing arm 13. The roller 14 rolls and rotates along the groove curve track in the concave-convex di...

Problems solved by technology

[0003] like Figure 5 , 6 , 7. At present, the clamping device of the fully automatic blow molding machine is to install the roller 14 at the bottom of the swing arm 13. The roller 14 rolls and rotates along the groove curve track in the concave-convex disc inner groove, and the roller is installed at the bottom of the palm 15. 16. The roller 16 and the slide rail 17 are connected by a large tension spring 18, so that the roller 16 is always close to the outer surface of the concave-convex wheel cam to rotate and roll automatically, and the roller 14 installed at the bottom of the swing arm 13 controls the front and rear telescopic movements of the manipulator. During this process, the elastic deformation of the large tension spring 18 will change, but the large tension spring 18 is always in a pulled up state. With the improvement of the blow molding efficiency of the bottle blowing machine, the clamping device needs to run faster, so it is inevitable As a result, the large tension spring 18 is more frequently and greatly stretched, and it is easy to make the large tension spring 18 loose, and the effect that the roller 16 is always close to the outer surface of the concave-convex wheel cam is not achieved, and it is easy to fatigue or even break the large tension spring 18 , which requires an additional manual shutdown for inspection and shutdown to replace the large tension spring 18, which not only increases production costs but also reduces production efficiency. The frequent shaking of the large extension spring 18 easily makes the stability of the whole device worse
