Description

Bulk screw bundle packing process and its equipment

The present invention relates to a bulk screw packing process and its equipment, in particular to a bulk screw packing process and its equipment which can count and package bulk screws into bundles.

Press, in the screw manufacturing industry, after the screw processing is completed, it must be packaged. The packaging process is to use the conveyor belt to convey the screws on the packaging line, and there are many operators on the packaging line, and the operators will put a large number of screws into the Inside a box, weigh the box, then tape the box, seal it and label it, and finally move it away. However, due to the serious shortage of labor in the current labor market, and occupational injuries such as waist injuries are likely to be caused during the process of moving goods, it is becoming more and more difficult to hire employees for packaging and moving goods. Moreover, manual packaging and handling is labor-intensive and time-consuming, and the above-mentioned deficiencies need to be improved.

In addition, the general screw packaging is usually packed in a large box as mentioned above, and this kind of packaging is not suitable for small-scale or DIY construction purposes. Even in workplaces where a large number of screws are used, the construction personnel will take them out of the box. The process of applying screws is inconvenient, and it is easy to stab your own fingers during the process of picking up a large number of screws, or take too much at one time and fall from your fingers, causing injuries to others; therefore, a kind of belt-type packaging is derived. There are several holes at intervals on a long nail belt, and a screw is embedded in each hole as a positioning package. However, this kind of packaging not only wastes the cost of the belt, but also produces a lot of plastic waste. At the same time, it needs to be replaced. The large material packaging box is used to pack the nail belt group, which is not easy for the builder to use. It needs to be taken out one by one for screw locking, which is quite time-consuming.

The reason is that, in view of this, the inventor has been adhering to years of rich experience in design, development and actual production in this related industry, and then researched and improved it to provide a bulk screw bundle manufacturing process and its equipment in order to achieve better practical value.

The main purpose of the present invention is to provide a bulk screw packaging process and its equipment, especially a packaging process and equipment that can package the bulk screws into bundles, so that the overall implementation and use of the package have more practical and functional characteristics.

The main purpose and effect of the bulk screw bundle packaging process of the present invention are achieved by the following specific technical means:

It mainly counts the number of screws to be packaged into piles through the fixed number calculation step, and then prepares the heat-shrinkable film material step with an appropriate size and length, and then passes the screw pile through the filming step to stack the screws into the heat-shrinkable film material, and the heat-shrinkable film material is heated and tightened through the shrinking film tightening step to bundle the packaging screws to complete the bulk screw packaging process; thus, the bulk screws are packaged one by one through the above-mentioned process steps Packed in bundles to achieve the convenience of supplying screws in small bundles.

In a preferred embodiment of the bulk screw bundle packing process and equipment of the present invention, the fixed number calculation step can calculate the screws to be packaged corresponding to the fixed number through a counting unit, so that the screws can be counted into a certain number of screw piles.

In a preferred embodiment of the bulk screw bundle packaging process and equipment of the present invention, the step of preparing the film material is to use heat-shrinkable film material, and cut an appropriate length of ring-shaped heat-shrinkable film material according to the length of the screw to be packaged.

In the preferred embodiment of the bulk screw bundle packing process and equipment of the present invention, the covering step is to put a certain amount of screws into the annular heat-shrinkable film material to complete the covering action.

In the preferred embodiment of the bulk screw bundle packing process and its equipment of the present invention, the shrinking film tightening step is to heat the outside of the pile of screws covered with a certain amount of heat shrinkable film material, so that the heat shrinkable film material is Temperature shrinks the tightening screw.

The main purpose and effect of the bulk screw bundle packing equipment of the present invention are achieved by the following specific technical means:

It is mainly provided with a turntable driven by power to rotate on the machine table, and several film placement cylinders are arranged on the upper ring of the turntable, and a film supply mechanism, a feeding mechanism, a heating mechanism, and a heating mechanism are sequentially arranged on the machine platform corresponding to the film placement cylinders. The shrink film mechanism and the blanking mechanism, wherein a film column is set in the film supply mechanism to transport the heat-shrinkable film material, and the film material is cut to an appropriate length and dropped into the film tube, and then The counting unit in the feeding mechanism counts the number of screws to be packaged, and falls into the film tube with heat-shrinkable film material, and then blows hot air to the corresponding film material through the heat-sealing shrinkable film mechanism, so that the number of screws can be The screw bundles are packed into bundles, and finally, the bundled screw bundles are clamped and discharged by the blanking mechanism; thereby, the bundled screw bundle procedure of the consistent operation of bulk screws is achieved.
