Description

Technical Field

[0001] This utility model relates to the field of hot melt equipment technology, and in particular to a nozzle for a filling woven bag packaging machine. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastics such as polyethylene and polypropylene. After the product is filled into the woven bag, a packaging machine is used to heat-seal the bag opening. The heat-seal mechanism of the packaging machine is the packaging nozzle.

[0003] Existing packaging machine nozzles typically use two heating plates to clamp the opening of a woven bag in the middle for heat melting to achieve the purpose of sealing. However, traditional packaging machine nozzles lack a buffer structure. When clamping the opening of a woven bag, it is easy to cause excessive compression due to the different thicknesses of the woven bags. If the compression is too tight and then heat-melted, the opening of the bag may not be able to maintain its original shape and may stick together, easily causing the woven bag seal to break and resulting in sealing failure. Moreover, the heat melt residue left on the surface of the heating plates during heat melting is inconvenient to clean and may affect the sealing process of the next woven bag opening.

[0004] Therefore, there is an urgent need to provide a nozzle for filling woven bag packaging machines to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the lack of buffer structure in the existing packaging machine nozzle. When it clamps the opening of the woven bag, it is easy to cause excessive compression due to the different thicknesses of the woven bags. After being compressed too tightly, it is easy for the bag opening to lose its original shape and stick together, which can easily cause the woven bag to break and result in sealing failure. Moreover, the hot melt residue left on the surface of the heating plate during hot melting is inconvenient to clean and can easily affect the sealing process of the next woven bag opening. This utility model provides a filling woven bag packaging machine nozzle.

[0006] To solve the above-mentioned technical problems, the present invention provides a nozzle for a woven bag filling machine, including a mounting base, and further comprising:

[0007] A heat-sealing assembly, wherein the heat-sealing assembly is disposed at the bottom of the mounting base;

[0008] The heat sealing assembly includes a displacement unit disposed inside the mounting base, a movable plate disposed at the bottom of the displacement unit, a heating element disposed on the side of the movable plate, and an adjustment unit disposed on the side of the heating element. A cleaning unit is disposed on the side of the heating element.

[0009] The present invention is further configured such that: a connecting post is provided opposite to the top of the mounting base, and a connecting plate is installed on the top of the connecting post.

[0010] The present invention is further configured such that: there are two sets of displacement units, and the two sets of displacement units are arranged opposite to each other on the inner side of the mounting base;

[0011] The displacement unit includes a guide rod installed inside the mounting base, a guide sleeve movably connected to the outside of the guide rod, and a pusher disposed on the side of the guide sleeve. The guide sleeve is installed on the top of the moving plate.

[0012] A limiting groove is formed on the inner top surface of the mounting base, and a limiting block is movably arranged inside the limiting groove. The limiting block is installed on the top of the guide sleeve.

[0013] The present invention is further configured such that: an opening is provided at the bottom side of the movable plate, and the heating element is movably disposed inside the opening;

[0014] The heating element includes a heating base and a heat-conducting plate installed on the side of the heating base.

[0015] The present invention is further configured such that: a connecting plate is installed at the bottom of the movable plate, and there are two sets of adjustment units, the two sets of adjustment units being arranged opposite to each other on the side wall of the connecting plate;

[0016] The adjustment unit includes a movable rod movably disposed on the side wall of the connecting plate, a limiting ring installed on the outside of the movable rod, and a pressing member disposed on the side of the limiting ring. A limiting sleeve is threadedly connected to the outside of the movable rod, and one end of the movable rod is fixedly connected to the side of the heating element.

[0017] The present invention is further configured such that: there are two sets of cleaning units, and the two sets of cleaning units are respectively disposed on the side of the two sets of heating elements;

[0018] The cleaning unit includes a scraper disposed on the side of the heating element, a movable frame mounted on the top of the scraper, and a crossbar mounted on the inner side of the movable frame. The bottom of the crossbar is provided with a trapezoidal frame, which is mounted on the side of the movable plate.

[0019] The present invention is further configured such that: the top surface of the mounting base has a through hole, and the movable frame is movably disposed inside the through hole.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model uses a heat-sealing component to push the guide sleeve to slide along the outside of the guide rod. When the guide sleeve slides, it will simultaneously drive the moving plate to move, thereby driving the heating element to move. This makes the two sets of heating elements located on both sides of the filling woven bag. Working with the heating seat, they transfer heat to the heat-conducting plate and seal the filling woven bag with the heat-conducting plate.

[0022] When the moving plate moves, it will work with the trapezoidal frame to press the crossbar, which in turn will work with the movable frame to move the scraper upward, thus separating the scraper from the heating element;

[0023] After the woven bags are sealed, the heating element is separated from the woven bag by the displacement unit. At this time, the scraper moves down under the gravity of the load-bearing block, thereby removing the hot melt residue remaining on the surface of the heating element in conjunction with the scraper, so as to facilitate the subsequent heat sealing process of the woven bags.

[0024] 2. This utility model uses an adjustment unit to adjust the squeezing force of the heating element through the cooperation of a limiting sleeve, a limiting ring, a squeezing element, and a movable rod. This adjusts the force when the heating element contacts the woven bag, preventing excessive force from causing the bag opening to break. Attached Figure Description
