Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production technology, specifically to a feeding device for plastic pipe production. Background Technology

[0002] Plastic pipes, as an important component of chemical building materials, are widely accepted by users for their superior performance, hygiene, environmental protection, and low consumption. The main types include UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene water supply pipes.

[0003] In the prior art, patent publication number CN202322421956.6 discloses a feeding mechanism for the production of large plastic pipes, including a support frame, a hopper bolted inside the support frame, a filter screen bolted inside the hopper, a transmission pipe arranged inside the support frame, an auger rotatably connected inside the transmission pipe via a bearing, a motor bolted to one end of the transmission pipe, and the output end of the motor bolted to the auger via a coupling;

[0004] The aforementioned mechanisms have some problems when feeding plastic granules. For example, plastic pipe production granules are often pre-treated and are relatively clean, so there is no need to filter metal impurities again. In comparison, adjusting the discharge speed and position of the plastic granule outlet is more important. During the conveying process, the Zhenggege conveying equipment is in a state of vibration. The mechanism does not have obvious structural support. If the amount of material conveyed is too large, the amplitude may be too large, which may cause it to tip over. Therefore, we propose a feeding device for plastic pipe production. Utility Model Content

The discharge opening adjustment mechanism 3 also includes a lead screw 37 and an opening and closing adjustment motor 39. The lead screw 37 is rotatably connected to the inside of the slide groove 36. The outer thread surface of the lead screw 37 is threadedly connected to the middle of the sliding seat 38. The right end of the mounting platform 35 is fixedly connected to the opening and closing adjustment motor 39. The output shaft of the opening and closing adjustment motor 39 is fixedly connected to the right end of the lead screw 37. The input end of the opening and closing adjustment motor 39 is electrically connected to the output end of the microcontroller 8. When the device is to be used, the microcontroller 8 can be controlled to rotate the output shaft of the opening and closing adjustment motor 39 in the forward and reverse directions, thereby driving the sliding seat 38 to adjust its left and right position in the slide groove 36, thereby driving the top connecting rod 34 to push the plate rotating seat 33 to adjust its position, thereby driving the angle adjustment plate 32 to rotate at a specified angle around the central axis of the pin shaft, thereby controlling the opening and closing of the angle adjustment plate 32. During this process, the opening and closing angle of the angle adjustment plate 32 can be adjusted appropriately to control the size of the discharge port 2. The size of the discharge port is determined by the left side of the angle adjustment plate 32 and the left side wall and front and rear inner walls of the discharge port 2. When the device is not in use, the top cover plate is engaged and the angle adjustment plate 32 is closed to prevent external dirt from contaminating the inside of the conveying cylinder 1.

The lower connecting rod 65 is rotatably connected between the front and rear inner walls of the movable frame 63 through a rotating rod. The upper end of the lower connecting rod 65 is rotatably connected to the cylinder connecting seat 66. The upper end of the cylinder connecting seat 66 is fixedly connected to the middle of the outer arc surface of the material conveying cylinder 1.

At this time, the external oil pump can be adjusted, the telescopic cylinder 62 can be operated, and the telescopic end of the telescopic cylinder 62 can be extended or retracted by a specified length, thereby adjusting the distance between the mobile frame 63 and the support 5. Then, the right side of the material conveying cylinder 1 is pushed by the lower connecting rod 65. At this time, the material conveying cylinder 1 will rotate at a specified angle around the central axis of the rotating shaft, thereby adjusting the position of the outlet 2 and completing the feeding operation. During this period, the size and height of the inlet can be adjusted in real time according to the position of the plastic pipe production equipment.

[0029] The working principle of the feeding device for plastic pipe production provided by this utility model is as follows: When using this device, the microcontroller 8 can be controlled to rotate the output shaft of the opening and closing adjustment motor 39 in both directions, thereby driving the sliding seat 38 to adjust its left and right position within the slide groove 36. This, in turn, drives the top connecting rod 34 to push the plate rotating seat 33 to adjust its position, thereby driving the angle adjustment plate 32 to rotate at a specified angle around the central axis of the pin shaft. This controls the opening and closing of the angle adjustment plate 32. During this process, the opening and closing angle of the angle adjustment plate 32 can be adjusted to control the size of the discharge port 2. The size of the discharge port is determined by the left side of the angle adjustment plate 32, the left side wall of the discharge port 2, and the front and rear inner walls. At this time, the external oil pump can be controlled to operate the telescopic cylinder 62, and the telescopic end of the telescopic cylinder 62 extends to a specified length. The telescopic mechanism adjusts the distance between the movable frame 63 and the support 5, and then pushes the right side of the feeding cylinder 1 through the lower connecting rod 65. At this time, the feeding cylinder 1 will rotate at a specified angle around the central axis of the rotating shaft, thereby adjusting the position of the discharge port 2 to correspond to the upper and lower positions of the inlet of the plastic pipe production equipment. After the adjustment is completed, the microcontroller 8 can be controlled to start the feeding motor. The output shaft of the feeding motor rotates, thereby driving the feeding auger 4 to rotate. At this time, the granules for plastic pipe production can be poured into the feeding hopper 9. The granules for plastic pipe production are concentrated downward through the inclined plate 7 and then fall into the feeding cylinder 1. Then, with the feeding auger 4, they are conveyed obliquely to the left in the feeding cylinder 1 and finally discharged from the discharge port 2, completing the feeding operation. During this period, the size and height of the inlet can be adjusted in real time according to the position of the plastic pipe production equipment.

[0030] It is worth noting that the microcontroller 8 disclosed in the above embodiments is specifically model S7-200. The opening and closing adjustment motor 39, the material conveying motor, and the telescopic cylinder 62 can be freely configured according to the actual application scenario. It is recommended that the opening and closing adjustment motor 39 be a 42A03N model stepper motor, the material conveying motor be a CV-22 model geared motor, and the telescopic cylinder 62 be a 2TGI-95×600 model telescopic hydraulic cylinder. The microcontroller 8 controls the operation of the opening and closing adjustment motor 39 and the material conveying motor using methods commonly used in the prior art.
