Automatic film-cover and heat-seal device for cylindrical coil

Abstract

The invention discloses an automatic film-cover and heat-seal device for cylindrical coil and belongs to the technical field of machinery. The automatic film-cover and heat-seal device for cylindricalcoil comprises a main frame; a pair of moving tracks are fixedly connected to an upper end of the main frame; a moving device body is connected to the moving tracks; a pair of lifting mechanical armsare connected to a lower end of the moving device body; a conveying belt is placed at one side of the main frame; a cylindrical thin film roll material body is placed on the conveying belt; an air bubble film coil rack is placed at one side of the main frame; an air bubble film rolling rack is provided with an edge correcting device which can effectively guarantee that the air bubble film is drawn to a table top in the unified direction; It utilizes two lifting and foldable-unfoldable film-cover rods, which are similar to shell opening and closing, and the bubble film is applied from the bottom to the top of the coil surface. When the bubble film reaches to the uppermost end, the heating rod heats the contact surface. By heat sealing the interface of the bubble film, it is possible to quickly cover the bubble film on the end faces of the coils of different diameters for heat sealing.

Description

technical field [0001] The invention relates to the field of machinery, and more specifically, relates to an automatic film-coating heat-sealing device for cylindrical coils. Background technique [0002] Enterprises that produce plastic film need to roll the plastic film into a cylindrical coil for the convenience of transportation. However, the plastic film is easy to be directly damaged during transportation, and the coil needs to be protected. Generally, a protective film is used. [0003] The coiled material is a cylindrical plastic film roll, which needs to be packaged before it can be transported to various places. At this stage, the industry generally uses manual packaging. Due to the large production volume, more labor is required to complete this function. The existing packaging method is to manually pack the bubble film according to The width of the coil is cut, and then the air bubble film is wrapped on the surface of the coil and the opening is glued together wi...

[0003] The coil is a cylindrical plastic film roll, which needs to be packaged before it can be transported to various places. At present, the industry generally uses manual packaging. Due to the large production volume, it requires more labor to complete this function. The existing packaging method is to manually pack the bubble film according to The width of the coil is cut, and then the air bubble film is wrapped on the surface of the coil and the opening is glued together with tape. Now, due to the large changes in the diameter and width of the coil, the automatic cutting and coating equipment has not yet been solved in the market.
