Description

Technical Field

[0001] This utility model relates to extruders, specifically to an extruder for wire and cable sheaths. Background Technology

[0002] Extrusion machines are important plastic machinery. Most plastic products can be produced and manufactured by extrusion molding. Wire and cable sheaths need to be extruded using an extrusion machine during processing.

[0003] Existing wire and cable sheath extruders are in a high-temperature softened state after extruding the cable sheath. Because the tubular structure of the cable sheath lacks internal support after extrusion, the cable sheath is prone to collapse, causing the inner walls of the cable sheath to stick together, thus reducing the forming quality of the cable sheath.

[0004] Therefore, an extrusion machine for wire and cable sheaths is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a wire and cable sheath extruder. The purpose of this wire and cable sheath extruder is to prevent the wires and cables from collapsing after extrusion, thereby preventing the inner walls of the wire and cable sheaths from sticking together.

[0006] To solve the above technical problems, the present invention is achieved through the following solution: The present invention provides an extruder for wire and cable sheathing, comprising a horizontal extruder body and a docking plate disposed at the discharge end of the extruder body. The top of one end of the extruder body has a hopper, which communicates with the inner cavity of the extruder body.

[0007] The wire and cable sheath extruder also includes a docking platform fixed to the outside of the docking plate. The docking platform has a discharge port, and a channel is formed between the discharge port, the docking plate, and the extruder body. The wire and cable sheath extruder also includes a baffle assembly, which has a baffle that blocks the discharge port and a support shaft that is vertically connected to the outside of the baffle. The baffle has multiple connecting internal and external guide holes, and the support shaft has a cooling structure.

[0008] Furthermore, the flow guide ring array is distributed in the peripheral area at the connection between the support shaft and the baffle.

[0009] Furthermore, the support shaft is fitted with a limiting sleeve, which abuts against the baffle and surrounds the guide hole.

[0010] Furthermore, the docking platform is provided with a through hole extending to the discharge port.

[0011] Furthermore, the cooling structure includes a cooling pipe disposed inside the support shaft, with the inlet pipe of the cooling pipe leading out from one of the through holes and the outlet pipe of the cooling pipe leading out from the other through hole.

[0012] Furthermore, the cooling pipe is a spiral structure pipe.

[0013] Furthermore, coolant flows through the cooling pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The wire and cable sheath extruder of this utility model uses the cooperation of the outer limiting sleeve and the inner support column to limit and support the extruded wire and cable sheath, and uses the cooling structure in the inner support shaft to achieve cooling and molding of the wire and cable sheath.

[0016] 2.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Example 1: The specific structure of this utility model is as follows:

[0026] Please refer to the appendix. Figure 1-5 This utility model discloses an extruder for extruding wire and cable sheaths, comprising a horizontal extruder body 1 and a docking plate 2 disposed at the discharge end of the extruder body 1. One end of the extruder body 1 has a hopper at its top, which communicates with the inner cavity of the extruder body 1. The extruder also includes a docking platform 3 fixed to the outside of the docking plate 2, the docking platform 3 having a discharge port 4, forming a channel between the discharge port 4, the docking plate 2, and the extruder body 1. The extruder also includes a baffle assembly, which has a baffle 5 plugged into the discharge port 4 and a support shaft 8 vertically connected to the outside of the baffle 5. The baffle 5 has multiple internal and external guide holes 7, and the support shaft 8 has a cooling structure.

[0027] The docking platform 3 is provided with a through hole leading to the discharge port 4, which is used for installing pipes. The cooling structure includes a cooling pipe 9 located inside the support shaft 8. The inlet pipe 10 of the cooling pipe 9 is led out from one of the through holes, and the outlet pipe 11 of the cooling pipe 9 is led out from the other through hole. The cooling pipe 9 is a spiral structure pipe, and coolant flows through the cooling pipe 9. A circulating pump is installed in the coolant circulation pipeline, and a coolant storage tank is set in the circulation pipeline.

[0028] The extruder body 1 is equipped with a heating device and a pusher screw structure. Plastic granules are poured from the hopper into the inner cavity of the extruder body 1. After being heated, the plastic granules are melted. Then, the pusher screw rotates, causing the melted gel-like sheath material to move towards the discharge port 4.

[0029] The flow guide holes 7 are arranged in a ring array in the outer area where the support shaft 8 connects to the baffle 5. The flow guide holes 7 are used to extrude the sheath of the wire and cable.

[0030] To prevent the wire and cable sheath from collapsing, a support shaft 8 is vertically installed on the discharge side of the baffle 5. The support shaft 8 supports the wire and cable sheath and simultaneously cools it through a cooling structure. This accelerates the hardening of the extruded wire and cable sheath, preventing it from collapsing and deforming, thus ensuring the quality of the wire and cable sheath.

[0031] The support shaft 8 is fitted with a limiting sleeve 6, which abuts against the baffle 5 and surrounds the guide hole 7. The function of the limiting sleeve 6 is to prevent the newly extruded wire and cable sheath from detaching from the support shaft 8.

[0032] Example 2:

[0033] The following is the working principle of the wire and cable sheath extruder of this utility model:

[0034] 1. In the extrusion molding of wire and cable sheaths, the gel-like plastic enters the discharge port 4 and is then squeezed through the guide hole 7 into the space between the support shaft 8 and the limiting sleeve 6.

[0035] 2. The space between the support shaft 8 and the limiting sleeve 6 limits and shapes the extruded gel-like plastic, forming a tubular structure. At this time, coolant is pumped into the inlet pipe 10 through a circulating pump. Under the guidance of the inlet pipe 10, the coolant enters the cooling pipe 9. Since the cooling pipe 9 is spiral-shaped, the coolant flowing in the cooling pipe 9 absorbs heat and cools the wire and cable sheath passing through, thus facilitating efficient cooling of the wire and cable sheath outside the support shaft 8. This facilitates the cooling and molding of the wire and cable sheath. With the support of the inner support shaft 8, the wire and cable sheath can be fully cooled and molded to have sufficient strength before detaching, avoiding the lack of support in the extruded wire and cable sheath, and thus solving the problem of soft collapse and deformation of the inner wall of the wire and cable sheath.

[0036] In summary, this utility model of a wire and cable sheath extruder uses the cooperation of an outer limiting sleeve and an inner support column to limit and support the extruded wire and cable sheath, and utilizes the cooling structure within the inner support shaft to achieve cooling and molding of the wire and cable sheath. This utility model ensures that the wire and cable sheath has sufficient strength after cooling and molding under support, preventing the extruded wire and cable sheath from collapsing and deforming due to insufficient support, thus guaranteeing the quality of the extruded wire and cable sheath.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
