Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a conveyor belt type extruder for producing communication cables. Background Art

[0002] The outer sheath of the communication cable is a plastic product, which covers the conductor for protection. An extruder is used in the processing of the communication cable outer sheath. First, the raw materials of the communication cable outer sheath are usually specially designed polymer particles or other plastic raw materials. The raw materials enter the extruder, and they will be twisted through a rotating cylinder. The molten raw materials are then extruded from the extrusion head of the extruder. The shape of the extrusion head will determine the appearance of the final product. Finally, the outer wall of the extruded communication cable is guided by a conveyor belt-type guide device for cooling and other subsequent processing.

[0003] However, the outer wall of the communication cable cannot be easily adjusted to the shape of the product during use. The extrusion head is mostly fixed by welding or threaded turning parts, which is very unstable when adjustments are required due to changes in product demand. For this reason, we propose a conveyor belt extruder for the production of communication cables to solve the existing problems. Utility Model Content

[0006] Preferably, a support frame is provided at the lower end of the extrusion box, and the support frame supports the lower end of the extrusion box.

[0007] Preferably, one end of the extrusion tube is closed, the output shaft of the second motor is connected to one end of the auger, and the auger is rotatably mounted inside the closed portion of the extrusion tube. The closed portion of the extrusion tube supports the auger rotation and is also used for the installation of the second motor.

[0008] Preferably, a feed pipe is installed through the upper end of the heating cylinder, and the feed pipe is used for inputting the raw material of the communication cable sheath.

[0009] Preferably, the conveying rollers are inclined, and the two groups of conveying rollers are relatively distributed, and the inclined surfaces of the two groups of conveying rollers are in an inverted eight-shaped shape. The inverted eight-shaped conveying roller inclined surfaces limit the extruded communication cable sheath, preventing the communication cable sheath from deviating to the front and rear sides, and at the same time guide and support the communication cable sheath, and guide and support the communication cable sheaths of different specifications.

[0010] Preferably, both sides of the lower end of the travel seat are provided with symmetrically distributed sliders, the mounting frame is provided with symmetrically distributed guide rails, and the sliders are slidably mounted on the outer walls of the guide rails. The travel seat slides on the guide rails through the sliders, which guides the travel seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model heats the raw material in a heating cylinder, and after the hot-melt raw material flows to the conveying pipe, the raw material is extruded by rotating the auger. Under the extrusion of the subsequent raw material, the extrusion box is extruded through the corresponding extrusion tube to realize the extrusion processing of the communication cable sheath. A plurality of extrusion tubes of different specifications are respectively arranged at one end of the extrusion box. When the specification of the communication cable sheath changes, the corresponding extrusion tube is opened to realize the processing and adjustment of the communication cable sheath with different requirements. The guide structure is adjustable, which is convenient for conveyor belt-type diversion and transportation of the communication cable sheath extruded at different positions, and is convenient for subsequent cooling and other processing.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 4 As shown, the utility model proposes a conveyor belt extruder for producing communication cables, comprising a motor 1, a travel seat 2, an extrusion box 3, a conveying pipe 5, a heating cylinder 7 and a mounting frame 8, a conveying pipe 5 is installed through one end of the extrusion box 3, an auger 15 is rotatably installed inside the conveying pipe 5, a heating cylinder 7 is arranged above the conveying pipe 5, a connecting pipe 16 installed through the conveying pipe 5 is arranged at the lower end of the heating cylinder 7, a motor 2 6 is arranged at one end of the conveying pipe 5, extrusion tubes 12 with equidistant distribution and different apertures are arranged at one end of the extrusion box 3, a support frame 4 is arranged at the lower end of the extrusion box 3, one end of the extrusion tube 12 is in a closed state, the output shaft of the motor 2 6 is connected to one end of the auger 15, and the auger 15 is rotatably installed inside the closed part of the extrusion tube 12, and a feed pipe 14 is installed through the upper end of the heating cylinder 7.

[0020] Implementation steps based on Example 1: The raw materials for the production of the outer wall of the communication cable are transported to the inside of the heating cylinder 7 through the feed pipe 14. After the heating cylinder 7 heats and melts the material, the flowing liquid flows to the conveying pipe 5 through the connecting pipe 16. The motor 2 6 drives the auger 15 to rotate to twist and transport the hot-melt liquid. After the raw materials inside the extrusion box 3 are saturated, the continuously extruded raw materials are output through the extrusion tube 12 under the action of the extrusion force to form a communication cable sheath with adapted specifications. It is worth mentioning that the opening of the extrusion tube 12 requires an adapted fixed plug or valve, which is closed when not applicable and opened with the corresponding extrusion tube 12 closure. This avoids the need to replace the extrusion equipment or the extrusion head when the specifications of the outer wall of the communication cable change, and the extrusion head cannot be replaced due to welding, or the problem of cumbersome replacement of the twisting parts is realized, so that the processing requirements of the outer skins of communication cables of different specifications can be adjusted, and the extrusion equipment is flexible to use.

[0022] In this embodiment, after the opened extrusion tube 12 is adjusted, the motor 1 drives the screw 11 to rotate, and the travel seat 2 slides on the guide rail 10 through the slider 9 to guide the travel seat 2. The screw 11 pushes the nut 13 to drive the travel seat 2 to move back and forth, and the position of the travel seat 2 changes. Corresponding to the opened extrusion tube 12, the bottom of the communication cable sheath extruded by the extrusion tube 12 is guided and supported, and the traction equipment is cooperated to carry out subsequent cooling and other processing. The adjustable conveyor belt conveying structure using the communication cable sheath is flexible to use and adapts to the needs of processing and production.
