Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1, the pressing rod of the present application is used in a garbage bag packing mechanism, and the front end of the pressing rod has a pressing surface 1, and the pressing surface 1 is adapted to be in pressing contact with a hot melt assembly 100. Because the extrusion rod of the existing straight rod structure is easy to deform under stress. The inventor increases the overall strength of the extrusion rod on the premise of not changing the basic structure of the extrusion rod. For this reason, the present embodiment is designed such that the rear end of the extrusion stem has a reinforcing surface adapted to prevent the contact portion of the extrusion stem with the hot melt assembly 100 from being deformed backward.

As shown in fig. 2, the reinforcing surface may be a rear convex surface 2 'protruding backward, and the rear convex surface 2' increases the overall width of the extrusion stem, which inevitably increases the structural strength. However, the increase of the width inevitably increases the consumption of materials and the cost is higher, so the structure has the optimization and improvement space.

As shown in fig. 3 and 4, the reinforcing surface is an arcuate surface 2, and the arcuate surface 2 is convex forward. The arcuate surface 2 may be in the shape of a circle, an ellipse, a parabola, a piecewise curve, a broken line segment, etc., or a truncated part thereof, and preferably, in this embodiment, an arc segment is selected, and the arcuate surface 2 actually forms an arch structure or an arc structure. The arrangement of the arch surface 2 enables the extrusion rod to present a structure of an arch bridge, so that larger backward acting force can be borne, the overall strength of the extrusion rod can be effectively increased, and the structural reliability of the extrusion rod is ensured. In addition, the arched surface 2 is of a forward concave structure, so that materials can be saved to a certain extent, and the cost is lower.

Preferably, the contact portion of the pressing rod with the hot melt assembly 100 has a central axis L, and the highest point of the arcuate surface 2 is collinear with the central axis L, so that the arcuate surface 2 has the greatest deformation resistance. Further, the arch surface 2 is symmetrically arranged by taking the central axis L as an axis, and is used for balancing the overall stress of the extrusion rod. Considering the stress strength of each position of the extrusion rod, the width of the extrusion rod is the smallest at the central axis L and extends towards two sides from the central axis L, and the width of the extrusion rod is gradually increased.

According to the specific structure of the garbage bag packaging mechanism, the two sides of the extrusion rod of the embodiment are provided with the fixed seats 3, and the fixed seats 3 at the two sides are suitable for being respectively and fixedly connected with the synchronous belts 200; the reinforcing surface extends to the fixing base 3 towards both sides. The arrangement of the two fixing seats 3 can enable the extrusion rod to run more stably, on the other hand, the stress on two sides of the extrusion rod is balanced, and the possibility of deformation of the extrusion rod can be reduced to a certain extent.

As a common arrangement of the garbage bag packaging mechanism, at least one side of the configured extrusion rod is provided with a guide hole 4, and the guide hole 4 is suitable for sliding to penetrate through the guide rod 300. The rear end of the extrusion rod is provided with a trigger piece 5, and the trigger piece 5 extends backwards and is higher than the reinforcing surface.

As a conventional molding means, the extrusion stem is adapted to be integrally injection molded, and the arcuate surface 2 is also easily injection molded, ensuring that the overall cost of the extrusion stem can be maintained at a low level.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
