Embodiment 1

[0027] A packaging bag stretching device of a packaging machine, such as figure 1 , figure 2 and image 3 As shown, it includes a fixed base 1 and a slide plate 2 hinged on the fixed base 1. A slide block 3 is provided on the slide plate 2. The slide block 3 is placed at the first position of the slide plate 2, and the slide block 3 slides from the first position to the second position. The position is such that the packaging bag 5 is stretched and kept in the stretched state. details as follows:

[0028] Such as figure 2 , image 3 and Figure 4 As shown, the slide plate 2 is hinged on the fixed seat 1 and is in an inclined state. When the packaging bag is used for the first time, the packaging bag 5 is placed on the slide plate 2. The opening of the packaging bag 5, the bag body of the packaging bag 5 is in a closed state, the slider 3 is a cylindrical structure, the front end of the slider 3 facing the first position is provided with a guide groove 31, and the slide...

Embodiment 2

[0030] Such as Figure 6 , Figure 7 As shown, the structure of the second embodiment is basically the same as that of the first embodiment, the difference is that the driving mode of the slider 3 is different, the slider 2 is in a horizontal state and does not rotate, the slider 3 is made of plastic and has a cylindrical structure, and the slider 3 A permanent magnet strip 32 is installed in the middle, and both sides of the slide plate 2 are provided with electromagnets 21. The position of the electromagnet 21 is higher than that of the permanent magnet strip 32, and attracts each other with the permanent magnet strip 32. The force received by the permanent magnet 32 ​​is balanced in the left and right directions. The slide plate 2 does not move in the left and right direction of the slide plate. The electromagnet 21 can make the slide block 3 counteract the gravity of the sliding part in the vertical direction, so that the slide block 3 can slide more easily. The electromag...

Embodiment 3

[0032] The mechanism of embodiment three is substantially the same as that of embodiment two. The slide plate 2 is in a horizontal state and does not rotate. The magnetic strips 32 repel each other, and the electromagnet 21 drives the slider 3 to reciprocate and slide between the first position and the second position of the slide plate 2 .

Abstract

The invention provides a packaging bag opening device of a packaging machine, and belongs to the technical field of packaging. According to the packaging bag opening device, a bag opening and a bag body can be kept in a continuous opening state when a packaging bag is used for packaging. The packaging bag opening device of the cup packaging machine comprises a fixing base and a sliding plate installed on the fixing base, a sliding block capable of being placed in the packaging bag is arranged on the sliding plate, the sliding block slides in a reciprocating mode at a first position and a second position on the sliding plate, and the packaging bag is opened when the sliding block slides from the first position to the second position. A mechanical arm clamps the packaging bag and enables the packaging bag to be kept in the opening state. According to the scheme, the sliding block is located in the packaging bag, the bag opening and the bag body of the packaging bag can be automatically opened and kept in the opening state, and the bag opening efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of packaging, and relates to a packaging device, in particular to a packaging bag opening device of a packaging machine. Background technique [0002] With the development of packaging technology, most packaging devices are completed in an automated way. This packaging machine can be applied to the packaging of tubular products such as cups and paper bowls. Disposable cups are now widely used in various occasions, and the scale of cup production is getting larger and larger. The production, stacking and packaging of cups are all completed by automated production lines. At present, the main steps of the automatic packaging of cups in the existing technology are firstly to unfold the plastic mold. After the plastic mold passes through the bending sheet, it presents a cylindrical structure with unencapsulated sides. After the stacking is completed, the cups are moved to the bent by the conveying mechanism. On...
