Description

Technical Field

[0001] The invention belongs to the technical field of extruded board production equipment, and in particular relates to a feeding device for extruded board production. Background Art

[0002] Extruded board, referred to as XPS board, is a rigid foamed plastic board made of polystyrene as the main raw material, with auxiliary materials, additives and fire retardants, heated and mixed, and injected with catalysts, and extruded. In the process of producing extruded board, the raw materials of extruded board are mostly granular, because the blocky raw materials are squeezed against each other in the conveying pipeline.

[0003] When the existing feeding device for extruded board production is working, after the granular raw materials are mixed with other substances and stirred, the granular raw materials condense together due to the adhesion of other raw materials, and then agglomeration occurs. This agglomeration will not only cause blockage of the discharge port, but may also cause the subsequent normal processing of the raw materials. The agglomerated materials need to be screened before processing, which reduces the functionality of the device. Summary of the invention

[0004] The present invention provides a feeding device for the production of extruded boards, and its purpose is to solve the problem that when the existing feeding device for the production of extruded boards is working, after the granular raw materials are mixed with other substances and stirred, the granular raw materials coagulate together due to the adhesion of other raw materials, and then agglomerate. This agglomeration will not only cause the blockage of the discharge port, but may also cause the subsequent normal processing of the raw materials. The agglomerated materials need to be screened before processing, which reduces the functionality of the device.

[0005] An embodiment of the present invention provides a feeding device for the production of extruded boards, including a feeding box, the side of the lower end of the feeding box is fixedly connected to a bracket, a material breaking assembly is installed inside the feeding box, a pair of material guide plates are symmetrically fixedly connected to the mouth of the upper end of the feeding box, the upper end of the feeding box is detachably connected to an upper box body, an automatic feeding assembly is installed in the upper box body, impact anti-sticking material assemblies are installed on the front and rear sides of the feeding box, and a discharge anti-blocking assembly is installed at the mouth of the lower end of the feeding box.

[0006] By adopting the above technical scheme, by adding materials into the upper box body, when the materials reach a certain weight, the automatic feeding component automatically opens the bottom of the upper box body and puts the materials on the guide plate, the guide plate guides the materials into the feeding box, the material scattering component scatters the fallen materials, and the scattered materials fall into the mouth of the lower end of the feeding box, and the discharge anti-blocking component stirs the materials to ensure the feeding of the materials and prevent the bottom of the feeding box from being blocked. In this process, the impact anti-sticking component impacts the feeding box, so as to vibrate the materials sticking to the inner wall of the feeding box, which not only ensures the cleanliness of the inner wall of the feeding box, but also avoids the waste of materials caused by the retention of materials inside the feeding box.

[0007] Furthermore, the material breaking up component is rotatably connected to two rotating shafts 1 on the inner wall of the feeding box and a motor fixedly connected to the outer wall of the feeding box, one end of one of the rotating shafts is connected to the output end of the motor, a plurality of groups of striking blades are fixedly connected to the outer peripheral surface of the rotating shaft 1, one end of the rotating shaft 1 is fixedly connected to a gear 1, and the two gears 1 are meshed and connected with each other.

[0008] By adopting the above technical solution, the motor drives the rotating shaft 1 to rotate, and the rotating shaft 1 drives the other rotating shaft 1 to rotate through the gear 1, so that the two rotating shafts 1 rotate together, so that the striking blade strikes the material block, thereby breaking up the material block.

[0009] Furthermore, the material guide plates are distributed above the two rotating shafts in an eight-shaped shape.

[0010] By adopting the above technical solution, it is ensured that the falling materials are guided to the rotation trajectory of the striking blade.

[0011] Furthermore, the automatic feeding assembly includes a discharge plate rotatably connected to the upper box body, and a support one is detachably connected to the lower wall surface of the discharge plate and the inner wall surface of the upper box body, and a support two is rotatably connected to the support one, and a telescopic rod is fixedly connected between the two supports two, and a spring one is provided on the outer side of the telescopic rod, and the two ends of the spring one are respectively connected to the two supports two.

[0012] By adopting the above technical solution, when the weight of the material on the discharge plate is greater than the supporting force of spring one, spring one contracts and the discharge plate rotates, thereby dropping the material on the discharge plate onto the guide plate, thereby realizing automatic quantitative loading and avoiding material blockage or equipment failure due to excessive rapid material release.

[0013] Furthermore, the automatic feeding assembly also includes a threaded rod movably arranged on two sides of the support, the threaded rod is slidably connected to the second support, and nuts are threadedly connected at both ends of the threaded rod.

[0014] By adopting the above technical solution, the length of the spring one is adjusted by adjusting the position of the nut on the threaded rod, thereby changing the supporting force of the spring one to meet different discharge requirements.

[0015] Furthermore, the impact anti-sticking material assembly includes gear 2 fixedly connected to the other end of the rotating shaft 1, rotating shaft 2 rotatably connected to the outer wall of the feeding box and a plurality of movable columns slidably connected to both sides of the feeding box, gear 3 is fixedly connected to the outer circumferential surface of the rotating shaft 2, the gear 3 is meshed with gear 2, the other end of the rotating shaft 2 is fixedly connected to a cam, both ends of the movable column pass through the wall of the feeding box, one end of the movable column on the outside is fixedly connected to a knocking rod, and one end of the movable column on the inside is fixedly connected to a limiting block, a spring 2 is provided on the outside of the movable column, both ends of the spring 2 are respectively connected to the limiting block and the feeding box, and one end of the knocking rod is on the rotation trajectory of the cam end.

[0016] By adopting the above technical solution, when the equipment is running, shaft one drives gear two to rotate, gear two drives gear three to rotate, gear three drives the cam to rotate, and the cam will push the knocking rod outward during rotation. During this process, spring two shortens, and when the knocking rod moves away from the knocking rod, the knocking rod is quickly pulled back under the elastic force of spring two, so that the knocking rod knocks the outer wall of the feeding box, thereby vibrating the material on the inner wall of the feeding box to prevent the material from sticking to the inner wall of the feeding box.

[0017] Furthermore, the circumference of gear three is equal to eight times the circumference of gear two.

[0018] By adopting the above technical solution, it is avoided that the gear three rotates too fast, causing the knocking rod to knock too fast and cause the outer wall of the feeding box to deform.

[0019] Furthermore, the discharge anti-blocking component includes a sprocket 1 fixedly connected to the rotating shaft 1 and a rotating shaft 3 rotatably connected to the lower port of the feeding box, a sprocket 2 is fixedly connected to the outer surface of the rotating shaft 3, and the sprocket 1 and the sprocket 2 are connected by a chain transmission, and a plurality of stirring rods are also fixedly connected to the outer surface of the rotating shaft 3.

[0020] By adopting the above technical solution, shaft one drives sprocket one to rotate during the rotation process, sprocket one drives sprocket two to rotate through the chain, and sprocket two drives the stirring rod on shaft three to rotate, thereby achieving stirring of the falling material, preventing the material from causing blockage of the lower port of the feeding box, and ensuring normal feeding of the device.

[0021] The beneficial effects of the present invention are:

[0022] The present invention adds materials into the upper box body. When the materials reach a certain weight, the automatic feeding component automatically opens the bottom of the upper box body and puts the materials onto the guide plate.

The motor 32 drives the rotating shaft 1 31 to rotate, and the rotating shaft 1 31 drives another rotating shaft 1 31 to rotate through the gear 1 34, so that the two rotating shafts 1 31 rotate together, so that the striking blade 33 strikes the material block, thereby breaking up the material block.
