Embodiment 1

[0027] like figure 1 , 2 As shown, a bag opening mechanism based on an automatic packaging machine includes a cylinder 1, a frame 2, and a shield 3. The cylinder 1 is vertically fixed on the frame 2, and the positioning rubbing rod 11 is fixed on the frame 1. The cylinder shaft 5 of the cylinder 1 is connected with the slider connecting block 6 through the joint bearing 4, and the slider connecting block 6 is installed on the slider of the linear guide rail 12, and the linear guide rail 12 is fixed on the frame 1. A rotating shaft 7 is installed on the slider connecting block 6, the upper end of the movable rubbing rod 9 is installed on the rotating shaft 7 through a bearing, and the middle part is installed on the guide shaft 8 through a deep groove ball bearing, and the guide shaft 8 is installed on the guide shaft 8 through a guide wheel. In the guide groove 20, the working surfaces of the positioning rubbing bar 11 and the movable rubbing bar 9 are symmetrically arranged ...

Embodiment 2

[0030] like Figure 7 to Figure 11 As shown, a bag opening mechanism based on an automatic packaging machine, compared with Embodiment 1, differs in that the positioning rubbing rod 11 is movably connected with the frame, and a guide block 16 is also fixed on the connecting block of the slider. The guide block 16 is provided with a second guide groove, the middle part of the positioning rubbing rod 11 is movably connected on the frame by the second rotating shaft 18, and the upper end is installed in the second guide groove by the second guide shaft 17. The guide groove makes the positioning rubbing bar break away from the self-sealing packaging bag in the initial state, and contacts with the self-sealing packaging bag in the working state. This kind of structure has increased opening size, is convenient to deliver the self-sealing packaging bag 14 to the middle of two rubbing bars.

Abstract

The invention provides a bag opening mechanism based on an automatic packaging machine. The bag opening mechanism comprises a positioning rubbing rod and a movable rubbing rod, wherein working surfaces of the positioning rubbing rod and the movable rubbing rod are symmetrically arranged on two sides of a self-sealing packaging bag, and at least one elastic anti-slipping layer is formed in each working surface relative to the self-sealing packaging bag; one end of the movable rubbing rod is hinged to a movable end of an air cylinder; the middle part of the movable rubbing rod is movably mounted in a guide groove through a guide device; and the shape of the guide groove is matched with the movement track of the movable rubbing rod, so that the working surface of the movable rubbing rod acts according to the shape of the guide groove when the air cylinder acts. The bag opening mechanism based on the automatic packaging machine, provided by the invention, has the advantages of providing simultaneous movement of press fitting and up-down displacement, guaranteeing the bag tearing success rate, guaranteeing the packaging efficiency and the packaging yield and the like.

Description

technical field [0001] The invention relates to a bag opening mechanism based on an automatic packaging machine. Background technique [0002] With the improvement of people's living standards and the faster and faster pace of life, consumers have higher and higher requirements for food packaging. In order to meet the requirements of consumers for convenient, fast, easy disassembly and carrying of food packaging, food manufacturers have successively launched self-sealing packaging bags. The bag pullers of traditional packaging machines all use vacuum suction cups to pull bags, and the success rate of opening bags with vacuum suction cups to pull self-sealing packaging bags is low. The main reason is that the seal of the self-sealing packaging bag has a strong fastening force; thus the success rate of opening the bag with a single vacuum suction cup is low. The success rate of tearing bags directly affects the packaging efficiency and packaging pass rate of the packaging ma...
