Description
Technical Field
[0001] This application relates to the field of pipe production equipment technology, and in particular to a discharge auxiliary structure for a composite pipe extruder. Background Technology
[0002] A composite pipe extruder is a device used to produce multilayer composite pipes. Its working principle involves bonding different material layers together through processes such as heating, plasticizing, and extrusion to form pipes with specific properties. Traditional extruders lack a discharge auxiliary structure, and the pipes are prone to deformation due to a lack of support when they are first extruded, resulting in substandard pipes. Therefore, a discharge auxiliary structure for a composite pipe extruder is proposed. Utility Model Content
[0003] To address the problem that traditional extruders lack a discharge auxiliary structure, and composite pipe extruders are prone to deformation due to lack of support when extruding composite pipes, this application provides a discharge auxiliary structure for a composite pipe extruder.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0017] This application discloses a discharge auxiliary structure for a composite pipe extruder, including a fixed base 1, a motor 2 fixedly installed on the top of the fixed base 1, a turntable 3 fixedly connected to the output end of the motor 2, the output end of the motor 2 and the turntable 3 being coaxially arranged, multiple sets of through grooves 5 being opened on the surface of the turntable 3, the through grooves 5 being distributed in a circular array, and a support pipe 4 being connected to each through groove 5, a cutting mechanism being provided on one side of the top of the fixed base 1, and an ejection mechanism being provided at the bottom of the fixed base 1.
[0018] Furthermore, the fixed seat 1 is bolted to the extruder frame, and the extruder discharge end is aligned with one of the through slots 5.
[0019] In this embodiment, the support tube 4 is used to support the extruded pipe. By setting a cutting mechanism, the pipe can be cut and segmented. The turntable 3 is driven by motor 2 to rotate, so that the support tube 4 can be aligned with the discharge end of the extruder in sequence. This can support each segment of the pipe, prevent the pipe from deforming during extrusion, and transfer the pipe to the bottom of the fixed seat 1 so that the ejection mechanism can push the pipe out of the support tube 4.
[0020] Furthermore, the ejection mechanism includes a first electric push rod 6 fixedly installed at the bottom of the fixed base 1. The telescopic end of the first electric push rod 6 is fixedly connected to a push plate 7. The push plate 7 is adapted to the inner surface of the through groove 5. The first electric push rod 6 can drive the push plate 7 to move into or out of the through groove 5.
[0021] In this embodiment, by driving the first electric push rod 6 to extend and retract, the push plate 7 can be moved. When the through groove 5 rotates to align with the push plate 7, the first electric push rod 6 is driven to extend, which moves the push plate 7 into the through groove 5, thereby pushing the pipe inside the support tube 4.
[0022] Furthermore, the cutting mechanism includes a second electric push rod 10 fixedly installed on the outer surface of the fixed base 1. The telescopic end of the second electric push rod 10 is fixedly connected to a connecting plate 9, and a cutting blade 8 is fixedly connected to the surface of the connecting plate 9.
[0023] Furthermore, the extension and retraction direction of the second electric push rod 10 is arranged radially along the turntable 3, and the cutting blade 8 is located between the turntable 3 and the extruder discharge end.
[0024] In this embodiment, by driving the second electric push rod 10 to extend and retract, the cutting blade 8 can be moved, thereby cutting the pipe and segmenting it.
[0025] It should be noted that the switch interfaces of the motor 2, the first electric push rod 6, and the second electric push rod 10 in this embodiment are all connected to an external power source via wires. The circuits and related drivers involved are all existing conventional technologies and will not be described in detail here.
