[0002] A pipe is a tubular structure or system used to transport liquids, gases or solid particles. Using molds to produce pipes is a common manufacturing method, such as prefabricated pipe molds and extrusion molds, which are used in pipe production operations.

[0003] When producing some plastic pipes, the raw material particles need to be introduced into the mold first. Since the mold feed port is relatively small, a hopper is needed to assist in feeding. However, if the raw materials are poured in too fast, the hopper outlet is prone to blockage, which will affect the feeding operation.

[0004] Therefore, it is necessary to provide a new vibration feeding structure for a pipeline production mold to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a vibration-type feeding structure for a pipeline production mold.

[0006] The vibrating material feeding structure of the pipeline production mold provided by the present invention comprises a base frame and a material storage box fixed on the base frame;

[0007] It also includes a screening bucket movably mounted on the material storage box and used to receive the raw materials inside the material storage box, and the bottom of the screening bucket is fixed to the lower hopper through a connecting tripod;

[0008] An auxiliary unloading mechanism is also installed inside the material storage box, and the auxiliary unloading mechanism includes a unloading roller rotating inside the material storage box and located directly above the discharge port, and the circumferential outer wall of the unloading roller is provided with a plurality of annularly distributed grooves for transferring raw materials;

[0009] A transmission member is installed between the auxiliary unloading mechanism and the screening bucket. During the rotation of the unloading roller, the transmission member is also used to drive the screening bucket and the unloading bucket to reciprocate in the vertical direction;

[0010] A directional feeding pipe group is also installed at the discharge end of the discharge hopper to introduce the screened raw materials into the mold.

[0011] Preferably, a transmission shaft is rotatably connected inside the storage box, and the unloading roller is fixed on the transmission shaft. A motor for driving the transmission shaft to rotate is also fixed outside the storage box. The unloading roller is driven to rotate by the transmission shaft so that the groove on the unloading roller faces the inside of the storage box or the discharge port of the corresponding storage box.

[0012] Preferably, a first positioning frame and a second positioning frame are provided between the storage box and the screening bucket, the first positioning frame is fixed on the screening bucket, the second positioning frame is fixed on the storage box, and a first spring is fixed between the first positioning frame and the second positioning frame.

[0013] Preferably, a third positioning frame is fixed to one side of the storage box, a first positioning rod is fixed to the third positioning frame, and a second positioning rod is fixed to one side of the screening bucket, the first positioning rod and the second positioning rod are both rotatably connected with rings, and a connecting rod is fixed between the two rings.

[0014] Preferably, the transmission member comprises a driving pulley, and the driving pulley is concentrically fixed on the transmission shaft;

[0015] A positioning shaft is also rotatably connected to the side of the screening bucket, a concentrically arranged driven pulley is fixed on the positioning shaft, the driven pulley and the driving pulley are connected through a transmission belt, and an eccentric counterweight is also fixed on the positioning shaft.

[0016] Preferably, the diameter of the driving pulley is greater than the diameter of the driven pulley.

[0020] Compared with the related art, the vibration feeding structure of the pipeline production mold provided by the present invention has the following beneficial effects:

[0021] 1. In this device, the raw materials can be stored in the storage box, and then the motor drives the unloading roller to rotate.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] See also Figures 1 to 9 , an embodiment of the present invention provides a vibration type feeding structure of a pipeline production mold, the vibration type feeding structure of the pipeline production mold comprising:

[0041] A base frame 1 is provided with a storage box 2, the upper end of the storage box 2 has a feed port, the lower end has a discharge port, a screening hopper 4 is provided at a position corresponding to the discharge port at the lower end of the storage box 2, and a lower hopper 6 is provided below the screening hopper 4 through a connecting tripod 5;

[0042] Auxiliary unloading mechanism 3, the auxiliary unloading mechanism 3 is installed inside the storage box 2, and is used to quantitatively introduce the raw materials inside the storage box 2 into the screening bucket 4;

[0043] The transmission member 7 is installed between the auxiliary unloading mechanism 3 and the screening bucket 4, and is used to transmit the kinetic energy of the auxiliary unloading mechanism 3 when it is running, and drive the screening bucket 4 to reciprocate in the vertical direction;

[0044] The directional feeding pipe group 8 is installed at the discharge end of the discharge hopper 6 and is used to introduce the raw materials into the mold.

[0045] It should be noted that: in the device, the material storage box 2 is a container for holding raw materials, which can hold a sufficient amount of raw materials at one time for supplying the mold to perform the production operation of the pipeline;

[0046] The auxiliary unloading mechanism 3 is installed inside the material storage box 2 to export the raw materials inside the material storage box 2 and can control the amount of one-time export, so that there will be no blockage in the process of the raw materials entering the mold, ensuring normal loading operation;

[0047] The screening bucket 4 is movably mounted on the storage box 2, so it has a certain displacement floating amount, and the screening bucket 4 and the auxiliary unloading mechanism 3 are connected by a transmission member 7. Therefore, during the operation of the auxiliary unloading mechanism 3, the transmission member 7 can be driven to move together, thereby driving the screening bucket 4 to produce a reciprocating motion in the vertical direction, that is, vibration. When the screening bucket 4 is in a vibrating state, the raw materials on it can be better screened, and the raw materials with a relatively small particle size will fall into the unloading hopper 6, while the raw materials with a relatively large particle size will be led out from the unloading end of the screening bucket 4, and then can be crushed for the second time, so that the uniformity of the raw materials can be better guaranteed and the processing quality of the subsequent pipelines can be improved;

[0048] The directional feeding pipe group 8 is installed at the discharge end of the discharge hopper 6. Therefore, the raw materials meeting the particle size will be introduced into the mold through the directional feeding pipe group 8 to perform the production function of the pipeline; at the same time, the discharge ends of the screening bucket 4 and the discharge hopper 6 are staggered, which makes it more convenient to install the directional feeding pipe group 8.

[0049] In the embodiments of the present invention, please refer to Figure 3 The auxiliary unloading mechanism 3 includes a transmission shaft 32 rotating inside the storage box 2, and a motor 31 driving the transmission shaft 32 to rotate is installed outside the storage box 2, and a unloading roller 33 is fixed on the transmission shaft 32, and a plurality of annularly distributed grooves 34 are opened on the circumferential outer wall of the unloading roller 33.

[0050] It should be noted that: when the auxiliary unloading mechanism 3 is used for unloading, the motor 31 drives the transmission shaft 32 to rotate, thereby driving the unloading roller 33 to rotate. The outer wall of the circumference of the unloading roller 33 has a plurality of annularly distributed grooves 34, so the smoothness of the outer wall of the circumference is relatively low, and the raw materials inside the storage box 2 can be stirred during the rotation process, so that the accumulated raw materials are looser, and part of the raw materials will enter the groove 34; and when the unloading roller 33 continues to rotate to the corresponding discharge port, the raw materials inside the groove 34 will be discharged from the discharge port and fall into the screening bucket 4, so as to realize the quantitative unloading of the raw materials;

[0051] The unloading roller 33 preferably has a hollow structure so as to reduce its own weight and reduce energy consumption during operation when used for unloading.

[0052] In the embodiments of the present invention, please refer to Figures 4 to 6 A first positioning frame 41 and a second positioning frame 42 are also provided between the storage box 2 and the screening bucket 4. The first positioning frame 41 is fixed on the screening bucket 4, and the second positioning frame 42 is fixed on the storage box 2. A first spring 43 is fixed between the first positioning frame 41 and the second positioning frame 42;

[0053] A third positioning frame 44 is also fixed to one side of the storage box 2, and a first positioning rod 45 is fixed to the third positioning frame 44, and a second positioning rod 46 is also fixed to one side of the screening bucket 4. The first positioning rod 45 and the second positioning rod 46 are both rotatably connected with a ring 47, and a connecting rod 48 is fixed between the two rings 47.

[0054] It should be noted that: for the installation of the screening bucket 4, its own stability is mainly ensured by the first spring 43 and the connecting rod 48, and the two ends of the connecting rod 48 are installed on the first positioning rod 45 and the second positioning rod 46 through the ring 47. Therefore, the screening bucket 4 itself has a certain vertical displacement floating amount, so that it can vibrate.

[0055] In the embodiments of the present invention, please refer to Figure 8 , the transmission member 7 includes a driving pulley 71, and the driving pulley 71 is concentrically fixed on the transmission shaft 32;

[0056] A positioning shaft 72 is also rotatably connected to the side of the screening bucket 4, and a concentrically arranged driven pulley 73 is fixed to the positioning shaft 72. The driven pulley 73 and the driving pulley 71 are connected through a transmission belt 74. An eccentric counterweight 75 is also fixed to the positioning shaft 72.

[0057] At the same time, a fourth positioning frame 76 is fixed to one side of the screening bucket 4, and a slide rod 77 is slidably connected to the fourth positioning frame 76, and a baffle 78 is fixed to the slide rod 77, and a second spring 79 is also sleeved thereon, and one end of the second spring 79 is pressed against the fourth positioning frame 76, and the other end is pressed against the baffle 78. One end of the slide rod 77 is rotatably connected to a tensioning adjustment wheel 710, and the tensioning adjustment wheel 710 is pressed against the transmission belt 74.

[0058] It should be noted that: when the auxiliary unloading mechanism 3 is running, the transmission shaft 32 can drive the driving pulley 71 to rotate, and then drive the positioning shaft 72 to rotate through the transmission belt 74 and the driven pulley 73. An eccentric counterweight block 75 is also fixed on the positioning shaft 72. The eccentric counterweight block 75 generates centrifugal force during the rotation process, and the centrifugal force can cause the screening bucket 4 to vibrate;

[0059] The diameter of the driving pulley 71 is greater than the diameter of the driven pulley 73, so the rotation speed of the driven pulley 73 will be faster, making the vibration of the screening bucket 4 more intense, and the material discharge and screening effects will be better;

[0060] When the screening hopper 4 is in a vibrating state, the distance between the driving pulley 71 and the driven pulley 73 will continuously change. When the distance shortens, the tension of the transmission belt 74 will decrease, so it is easy to slip during the transmission process. To address this, a tension adjusting wheel 710 is provided. The tension adjusting wheel 710 is installed on the movable slide rod 77. At the same time, the slide rod 77 is subjected to the elastic force of the second spring 79, enabling the tension adjusting wheel 710 to tightly press against the transmission belt 74, so as to make an adaptive adjustment according to the change in the tension of the transmission belt 74 itself, prevent the transmission belt 74 from slipping, and ensure stable transmission.

[0061] In an embodiment of the present invention, please refer to Fig. 9 , the directional feeding pipe group 8 includes a mounting pipe 81. The mounting pipe 81 is fixed to the discharging end of the blanking hopper 6. A bucket-shaped baffle 82 is fixed to the upper end of the mounting pipe 81. A blanking cone pipe 83 is arranged below the mounting pipe 81 for guiding raw materials into the mold. A folding pipe 84 is fixed between the mounting pipe 81 and the blanking cone pipe 83.

[0062] It should be noted that: the mounting pipe 81 is fixed at the discharging end position of the blanking hopper 6. The raw materials discharged from the blanking hopper 6 will enter the interior of the mounting pipe 81. A baffle 82 is provided at its upper end. The baffle 82 intercepts the raw materials, preventing the raw materials from splashing outside the mounting pipe 81. Then the raw materials can enter the blanking cone pipe 83 along the folding pipe 84. The blanking cone pipe 83 has a flange at its lower end, so it can be installed at the feeding port of the mold through the flange, thereby guiding the raw materials into the interior of the mold;

[0063] The folding pipe 84 is preferably a rubber hose, which can be folded and telescoped by itself. Therefore, when the screening hopper 4 and the blanking hopper 6 are in a vibrating state, it will generate corresponding shrinkage adjustments, so the influence on the screening hopper 4 and the blanking hopper 6 is relatively small.

[0064] The specific use process of this device is as follows:

[0065] (1), Raw material blanking;

[0066] The raw materials in the production pipeline are centrally introduced into the storage tank 2, and then the raw materials are discharged through the auxiliary blanking mechanism 3. That is, the motor 31 drives the transmission shaft 32 to rotate, and then drives the blanking roller 33 to rotate. The circumferential outer wall of the blanking roller 33 has a plurality of annularly distributed grooves 34. Therefore, the smoothness of its circumferential outer wall is relatively low. During rotation, it can stir the raw materials in the storage tank 2, making the piled-up raw materials looser. At the same time, some raw materials will enter the grooves 34. When the blanking roller 33 continues to rotate to the corresponding discharge port, the raw materials in the grooves 34 will be discharged from the discharge port and fall into the screening hopper 4, realizing quantitative blanking of the raw materials. The discharged raw materials will fall onto the screening hopper 4;

[0067] (2) Raw material screening;

[0068] During the operation of the auxiliary unloading mechanism 3, the transmission shaft 32 can drive the active pulley 71 to rotate, and then drive the positioning shaft 72 to rotate through the transmission belt 74 and the driven pulley 73. An eccentric counterweight 75 is also fixed on the positioning shaft 72. The eccentric counterweight 75 will generate centrifugal force during rotation, and the centrifugal force can make the screening bucket 4 vibrate. The vibration of the screening bucket 4 is used to screen the raw materials, that is, the raw materials with larger particle size are discharged from the unloading end of the screening bucket 4, and the raw materials with smaller particle size fall into the unloading hopper 6, and are introduced into the mounting tube 81 from the unloading end of the unloading hopper 6, and finally enter the mold from the unloading cone tube 83.

[0069] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
