DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 , Figure 2 As shown, the utility model provides a pipeline discharging mechanism, comprising

[0024] A bracket 1, the top of the bracket 1 is a horizontal platform, the bracket 1 is provided with a guide feed roller 101, the guide feed roller 101 is arranged on the platform, and a certain number of guide feed rollers 101 can be selected according to the conveying length;

[0025] The shaping and anti-expansion mechanism 2 comprises a cylinder 210 horizontally fixedly arranged on the bracket 1, and a plurality of adjustment components 220 that can move radially are arranged in the cylinder 210, and each of the adjustment components 220 is connected to a shaping roller component 230 that can synchronously contact the pipeline 4. According to the length of the pipeline 4, a plurality of shaping and anti-expansion mechanisms 2 can be selectively arranged, and generally at least two groups are provided and are coaxially arranged;

[0026] A cleaning mechanism 3, the cleaning mechanism 3 is arranged on the bracket 1 and is located between the shaping and anti-expansion mechanism 2 and the guide feed roller 101, the cleaning mechanism 3 comprises two vertically arranged brush rollers, the brush rollers are rotatably connected to the bracket 1, and the pipeline 4 can pass through between the two brush rollers;

[0027] The adjusting assembly 220 drives the shaping roller assembly 230 to move along the radial direction of the cylinder 210, so that the multiple shaping roller assemblies 230 are in synchronous contact with the pipe 4, exerting a certain force on the outer wall of the pipe 4, preventing the pipe 4 from expanding outward and deforming after coming out of the pipe making machine outlet, thereby improving the forming quality of the pipe making machine;

[0028] like Figure 2 , Figure 3As shown, specifically, the inner wall of the cylinder 210 is provided with a plurality of first guide holes 211 arranged along the radial direction thereof. In this embodiment, four first guide holes 211 are provided, and the four first guide holes 211 are located in the same plane perpendicular to the axis of the cylinder 210, and the four first guide holes 211 are evenly distributed along the circumference of the cylinder 210. The adjustment assembly 220 includes a guide seat 221 movably arranged in the first guide hole 211, and a driving member drivingly connected to the guide seat 221, the driving member is used to drive the guide seat 221 to slide in the first guide hole 211, and the shaping roller assembly 230 is provided at one end of the guide seat 221 away from the cylinder 210;

[0029] Specifically, Figure 3 As shown, the bottom of the first guide hole 211 is provided with a movable hole 212 which is connected thereto and passes through the cylinder 210, the driving member comprises a rotating ring 222 rotatably sleeved outside the cylinder 210, a transmission rod 223 passing through the movable hole 212, and a positioning member for limiting the rotating ring 222, and the two ends of the transmission rod 223 are respectively connected to the inner wall of the rotating ring 222 and the guide seat 221 for rotation;

[0030] When the rotating ring 222 is rotated, the rotating ring 222 drives the transmission rod 223 to move, and the transmission rod 223 pushes or pulls the guide seat 221 to move, so that the multiple shaping roller assemblies 230 are in a state of folding or unfolding. After the adjustment is completed, the position of the rotating ring 222 is fixed by the positioning member, so that the position of the shaping roller assembly 230 is fixed;

[0031] Specifically, Figure 2 As shown, a movable sleeve is provided on the cylinder 210 with a limiting ring 224 located on one side of the rotating ring 222. The limiting ring 224 is slidably matched with the cylinder 210 and can only move linearly along its axial direction. The limiting ring 224 is also matched with the cylinder 210 through an elastic member 228 to make it contact with the rotating ring 222. The elastic member 228 is always in a compressed state. In this embodiment, the elastic member 228 is a spring. The rotating ring 222 and the limiting ring 224 are both provided with limiting teeth 225 that can cooperate with each other on the opposite sides.

[0032] In the initial state, under the elastic force of the elastic member 228, the rotating ring 222 cooperates with the limiting teeth 225 on the limiting ring 224. Since the limiting ring 224 is non-rotatable, it limits the rotational movement of the rotating ring 222.

[0033] The limiting ring 224 is pushed to move axially along the cylinder 210 so that the limiting teeth 225 are separated. At this time, the rotating ring 222 can rotate to adjust the position of the shaping roller assembly 230. After the adjustment is completed, the limiting ring 224 is loosened. Under the elastic force of the elastic member 228, the limiting ring 224 is reset, so that the limiting teeth 225 on both sides cooperate to limit the rotation of the rotating ring 222 again.

[0034] Specifically, Figure 4 As shown, the outer wall of the cylinder 210 is provided with a plurality of slide grooves 213 parallel to its axis, the inner wall of the limiting ring 224 is fixedly connected with a slider 226 that slides with the slide groove 213, and the elastic member 228 is located in the slide groove 213 and connects the slider 226 and the side wall of the slide groove 213.

[0035] In order to enable the roller 232 to fully contact the outer wall of the pipe 4 and prevent excessive force, in a further embodiment, a second guide hole 227 is provided at the end of the guide seat 221 away from the cylinder 210, and the shaping roller assembly 230 includes a guide rod 231 movably arranged in the second guide hole 227, a roller 232 fixedly arranged at the end of the guide rod 231 and freely rotatable, and a rigid spring 233 connecting the guide rod 231 and the bottom of the second guide hole 227. The side of the roller 232 is provided with an arc groove arranged around it.
