Embodiment 1

[0016] Such as figure 1 As shown, the present embodiment includes a guide roller 3 and a speed-limiting mechanism, and the guide roller 3 and the speed-limiting mechanism are respectively arranged on an external packaging machine 9, and the speed-limiting mechanism includes a support rod 1, a hand wheel 6, a connecting rod 2 and Press down device, one end of support bar 1 is hinged with the press down device by connecting rod 2, the other end of support bar 1 is screwed with handwheel 6, also includes the speed recorder 10 that is arranged on the cylinder of external packing machine 9. The guide roller 3 is separated from the cylinder 8 of the external packaging machine 9 by a certain distance, so that the packaging material 7 maintains a certain tension, and the speed limiting mechanism can control the rotational speed of the cylinder 8 of the external packaging machine 9, which acts as a speed limiter; The wheel 6 drives the support rod 1 to rotate, so that the pressing devi...

Embodiment 2

[0018] Such as figure 1 As shown, this embodiment is based on Embodiment 1, and the pressing device includes a roller 5 and a wheel handle 4 connected to each other, and the wheel handle 4 is connected to the support rod 1 through the connecting rod 2 . The set roller 5 can move together with the roller 8 of the external packaging machine 9, and the interaction force between the roller 5 and the roller 8 can be adjusted by adjusting the handwheel 6. The greater the frictional force between them, the greater the restriction on the speed at which the cylinder 8 rotates, and vice versa.

Embodiment 3

[0020] Such as figure 1 As shown, this embodiment is based on Embodiment 1 and Embodiment 2. As a preference, the roller 5 is a plastic roller. The texture of the roller 5 made of plastic is relatively soft, and when the relative force between the roller 5 and the roller 8 is relatively large, the roller 5 will not cause damage, imprints and other disturbances to the packaging material 7 .

[0021] Preferably, the connecting rod 2 is made of aluminum alloy. The connecting rod 2 is arranged between the pressing device and the support rod 1, and is used to connect and support the pressing device. The aluminum alloy material has strong hardness and light weight, which reduces the labor intensity when turning the handwheel 6. It also effectively avoids phenomena such as breakage and fracture of the connecting rod 2 .

Abstract

The invention discloses a method for keeping tension of a packaging bag in a packaging bag machining technology. A guide roller and a speed limiting mechanism are included and arranged on an outer packaging machine. The speed limiting mechanism comprises a supporting rod, a hand wheel, a connecting rod and a downward press device. One end of the supporting rod is hinged to the downward press device through the connecting rod, and the other end of the supporting rod is in threaded connection with the hand wheel. A speed recorder arranged on a roller of the outer packaging machine is further included. When the downward press device moves upwards, the limitation to the speed of the roller is weakened, and the feeding requirement of the packaging machine for fast packaging can be met. The speed recorder can record the rotating rate and the number of rotating turns of the roller, and data supporting is provided for operators, so that the hand wheel is adjusted in time, and the rotating speed of the roller is controlled.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a method for maintaining the tension of the packaging bag in the packaging bag processing technology. Background technique [0002] There are many types of packaging machines, and there are many kinds from different points of view. According to the product state, there are liquid, block, and granular packaging machines; according to the packaging function, there are internal packaging and outsourcing packaging machines; according to the packaging industry, there are packaging machines for food, daily chemicals, and textiles; According to the position, there are single-station and multi-station packaging machines; according to the degree of automation, there are semi-automatic and fully automatic packaging machines. At present, the general packaging machines on the market are composed of packaging equipment, rollers and packaging materials. The packaging materials are wound on the roller...
