Automatic toothpick bag packaging equipment

Abstract

The invention belongs to the technical field of toothpick packaging and discloses automatic toothpick bag packaging equipment. The automatic toothpick bag packaging equipment comprises a rack and a controller. A work tabletop is arranged on the rack. A plastic strip raw material frame, a plastic strip guide roller set, a first heat sealing device, a toothpick discharging hopper assembly, a sorting device, a second heat sealing device, a conveying device, a first hot cutting device, a second hot cutting device and a waste plastic strip recycling wheel are sequentially arranged on the rack from back to front. According to signals of a stroke control sensor, the controller controls the conveying device to convey a plastic strip and a toothpick bag main strip intermittently. During the period of the stop of the conveying device, the controller controls air cylinders in the first heat sealing device, the toothpick discharging hopper assembly, the second heat sealing device, the sorting device, the first hot cutting device and the second hot cutting device through electromagnetic valves to move. All the devices are linearly arranged on the work tabletop, the plastic strip or the toothpick main strip is conveyed in one direction, the structure is relatively reasonable, the toothpick discharging hopper assembly and the conveying device are designed into new structures, the structure is excellent, the performance is remarkable, and stability is good.

Description

technical field [0001] The invention belongs to the technical field of toothpick packaging, and relates to equipment for packaging toothpicks, in particular to equipment for automatically packaging toothpicks in plastic bags. Background technique [0002] The packing of toothpick mainly contains two kinds of ways, and a kind of is to adopt hard packaging can (box) to pack toothpick, and another kind is to adopt plastic tape to pack toothpick. In the early years, the packaging of toothpicks was done by workers purely by hand, which was extremely inefficient. With the development of automatic control technology, special toothpick packaging equipment began to appear, but mainly for the way of packaging toothpicks in cans. [0003] There are several difficulties in the automatic packaging of toothpicks, which are: 1. At least one end of the toothpick is pointed. When pushing vertically, the pointed end of the toothpick is easy to insert into the thin seam between the pushing par...

AI Technical Summary

Problems solved by technology

In the early years, the packaging of toothpicks was done by workers purely by hand, which was extremely inefficient. With the development of automatic control technology, special toothpick packaging equipment began to appear, but it was mainly for the way of packaging toothpicks in cans.

[0003] There are several difficulties in the automatic packaging of toothpicks. They are: 1. At least one end of the toothpick is pointed.

Causing the push mechanism to get stuck

2. The toothpick has the characteristics of small diameter and light weight. After the toothpick falls from the discharge hopper through the discharge port and enters the push bin by its own weight, the upper toothpick cannot be guaranteed to be absolutely flat.

The front-end pushing surface of the pushing mechanism cannot touch this part of the toothpick, but this part of the toothpick may move forward asynchronously with other pushed toothpicks. The rear end is located above the push mechanism, and when the push mechanism moves forward, this part of the toothpick will be cut off

3. As far as the form of plastic bag packaging is concerned, the tip of the toothpick can easily pierce the plastic bag. Choosing a tougher plastic material is certainly a solution, but it will undoubtedly increase the packaging cost

[0004] In addition, since the plastic bags are relatively soft and difficult to push, the realization of pulling the toothpicks added to the cutting process in the automatic bagging process is also a technical difficulty
