Description

TECHNICAL FIELD

[0001] The utility model relates to the corrugated pipe production field, especially the detachable insert structure for corrugated pipe forming module. BACKGROUND

[0002] In order to identify and product traceability requirements, plastic pipes usually need to be marked on the pipe during the production process. The traditional marking method includes using a code jet or a laser printer to mark on the pipe. This operation method consumes ink and other consumables. Another method is to integrate the identification into the forming module to complete the identification work directly in the forming process.

[0003] The original design structure places the engraved mark at the wave crest 11 of the corrugated pipe 10. Figure 1 The engraved mark is mainly realized by vacuum adsorption during the forming process, so the forming quality of the mark is affected by the process conditions such as vacuum degree and pipe blank temperature, and the engraved mark is not clear and consistent.

[0009] In one preferred embodiment of the utility model, the engraved insert is fixed with the insert groove through a clamping mechanism.

[0010] In one preferred embodiment of the utility model, a cavity is formed in the engraved insert, and the clamping mechanism is fixed in the cavity through a threaded structure.

[0011] In one preferred embodiment of the utility model, the through hole is contracted from inside to outside, a ball is placed in the through hole and is tightly pressed by spring so that the ball is engaged with the hole in the inlay groove when the lettering inlay part is fixed with the inlay groove.

[0012] In one preferred embodiment of the utility model, the lettering inlay part has side wings extending towards two sides, the side wings guide the lettering inlay part to be clamped into the inlay groove through the sliding groove structure.

[0021] In the description of the utility model, it should be explained that the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and the above description is simplified for the convenience of describing the utility model and is not indicative or suggestive of the device or element indicated must have a specific orientation, a specific orientation and operation, therefore, it cannot be understood as a limitation on the utility model.

[0022] ​As used in the specification, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. The terms "includes," "comprises," and "comprising," as well as the terms "includes," "comprises," and "comprising," when used in this specification, mean "consisting of" and also "consisting essentially of" but also encompass the more limited term "consisting of."

[0023] In the specification, when it is said that an element is "on", "fixed to", "connected to", "joined to" or "contacted" another element, the element can be directly on, fixed to, connected to, joined to or contacted with the other element, or an intervening element can be present.

[0024] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood, however, that the present application can be presented in many different forms and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide additional embodiments. In all the drawings, the same reference numerals refer to the same or similar elements.

[0025] Reference Figures 2 to 4 The structure of the lettering insert is shown, and letters for forming a mark on the bellows 10 are hollowed and etched on the top surface 21 of the lettering insert 20. Side wings 22 extending to both sides are provided on the side of the lettering insert 20, and a cavity 27 is formed inwardly on the lower side of the lettering insert 20, and a ball-type tensioning mechanism 23 is disposed in the cavity 27. Specifically, the ball-type tensioning mechanism 23 includes a housing 24 fixed in the cavity 27 by a threaded structure, and a resilient ball 26 disposed in the housing 24, and a through hole 27 is formed in the housing 24, and the resilient ball 27 is composed of a steel ball 26 and a spring 25, the outer diameter of the steel ball 26 is equal to the inner diameter of the through hole 27, so that the steel ball 26 can freely move in the through hole 27, and the through hole 27 is tapered from the inside to the outside, and the inner diameter of the end portion 28 near the outside is slightly smaller than the inner diameter of the main body portion of the through hole 27, so that the steel ball 26 is stopped when it reaches the end portion 28 and cannot be taken out, and only a part of the ball head is exposed. The spring 25 is disposed at the rear side of the steel ball 26 so that the steel ball 26 always tends to be close to the end portion 28.

[0026] Reference Figure 5, the molding module 30 has corresponding convex and concave parts 32 and 31, the convex part 32 is provided with at least one insert slot 33, the lettering insert 20 is clamped into the insert slot 33 through the sliding slot structure between the side wings 22 of the side part and the insert slot 33 and is integrated with the convex part 32. A hole 34 is opened in the center of the insert slot 33, when the lettering insert 20 is installed in place, the exposed part of the steel ball 26 from the end part 28 is embedded into the hole 34, so that the lettering insert 20 is not easy to be taken out of the insert slot 33. When the lettering insert 20 is removed, a rubber hammer is gently tapped along the insertion and installation direction of the lettering insert 20, and the lettering insert 20 can be removed.

[0027] The advantages of this insert structure are that the lettering insert 20 is arranged at the wave trough 12 of the corrugated pipe 10, considering that the pipe material at the wave trough 12 is formed by injection molding pressure on the convex part 32, the molding pressure fluctuation is small, so the pressure required for forming the lettering mark at this position is much smaller than that required at the wave crest 11, so that the lettering mark forming consistency is good and the mark is clear.
