Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold for producing double-strand extrusion mesh sleeves. Background Technology

[0002] In the fruit packaging industry, molds primarily use single-strand mesh sleeves for production. These sleeves have a small contact area with the fruit, which can cause significant pressure, especially on thin-skinned fruits like peaches and strawberries, leading to indentations. These indentations not only damage the integrity of the fruit's skin but also negatively impact its transport safety, thus shortening its shelf life. Therefore, existing technologies are significantly inadequate for the safe packaging and protection of fruit and urgently need improvement.

[0003] To address this issue, a thinner mesh sleeve production mold was designed. This innovative design significantly reduces the pressure exerted by the mesh sleeve when packaging fruits with thin skins, thus improving the packaging's shock and impact resistance. This, in turn, reduces the occurrence of indentations and enhances the protective effect of the fruit during storage, necessitating the use of this double-strand extrusion mesh sleeve production mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a double-strand extrusion mesh production mold, which solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-strand extrusion mesh production mold, comprising a T-shaped cylindrical mold block and a disc-shaped mold block. The upper end of the T-shaped cylindrical mold block has a first circular through hole, and the side wall of the T-shaped end of the T-shaped cylindrical mold block has several pairs of first semi-circular grooves. The upper wall of the disc-shaped mold block has four pairs of first circular grooves, and each of the four pairs of first circular grooves has a second circular through hole inside. The disc-shaped mold block has a second circular groove at a circular position, and the lower wall of the second circular groove has a third circular through hole. The third circular through hole has the same size as the T-shaped end of the T-shaped cylindrical mold block.

[0006] Preferably, four pairs of second semi-circular grooves are formed on the inner wall surface of the third circular through hole, and the four pairs of second semi-circular grooves are the same size as the four pairs of first semi-circular grooves.

[0007] Beneficial effects

[0008] This utility model provides a double-strand extrusion mesh sleeve production mold. In use, the rubber feed end of the T-shaped cylindrical mold block is connected to the gap between the disc-shaped mold block and the T-shaped cylindrical mold block. The through holes of the disc-shaped mold block and the T-shaped cylindrical mold block are then connected to a rotating device. During feeding, the T-shaped cylindrical mold block and the disc-shaped mold block rotate in opposite directions. A circular through hole is formed by the combination of the first and second semi-circular grooves, through which the rubber is discharged. By continuously combining the semi-circular through holes and through the reciprocating rotation of the T-shaped cylindrical mold block and the disc-shaped mold block, the rubber is spliced ​​into a mesh, thus forming the rubber sleeve. The rubber sleeve significantly reduces the pressure exerted by the mesh sleeve when packaging fruits with thin skins, improving the packaging's shock and impact resistance. It reduces indentation, enhances the pressure protection effect of the fruit during storage, and strengthens the safety of the goods. It is particularly suitable for long-distance transportation of fruit, helping to ensure that the fruit remains intact during transportation. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Please see Figure 1 This utility model provides a technical solution: a double-strand extrusion mesh sleeve production mold, including a T-shaped cylindrical mold block 1 and a disc-shaped mold block 2. The upper end of the T-shaped cylindrical mold block 1 is provided with a first circular through hole. Several pairs of first semi-circular grooves are provided on the side wall of the T-shaped end of the T-shaped cylindrical mold block 1. The upper wall of the disc-shaped mold block 2 is provided with four pairs of first circular grooves. Each of the four pairs of first circular grooves is provided with a second circular through hole. The disc-shaped mold block 2 is provided with a second circular groove at a circular position. The lower wall of the second circular groove is provided with a third circular through hole. The third circular through hole has the same size as the T-shaped end of the T-shaped cylindrical mold block 1.

[0013] In this embodiment, four pairs of second semi-circular grooves are provided on the inner wall of the third circular through hole, and the four pairs of second semi-circular grooves are the same size as the four pairs of first semi-circular grooves.

[0014] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0015] Example: In use, the rubber feed end of the T-shaped cylindrical mold block 1 can be connected to the gap between the rubber feed end and the disc-shaped mold block 2 and the T-shaped cylindrical mold block 1. The through holes of the disc-shaped mold block 2 and the T-shaped cylindrical mold block 1 are connected to the rotating device. During feeding, the T-shaped cylindrical mold block 1 and the disc-shaped mold block 2 can be driven to rotate in opposite directions. At this time, the first semi-circular groove and the second semi-circular groove combine to form a circular through hole, through which the rubber is discharged. By continuously combining the semi-circular through holes, the rubber is spliced ​​into a mesh by the reciprocating rotation of the T-shaped cylindrical mold block 1 and the disc-shaped mold block 2, thereby realizing the formation of the rubber sleeve.
