Description
Technical Field
[0001] The utility model belongs to the technical field of artificial leather production, and in particular relates to a composite conveyor for calendering artificial leather. Background Art
[0002] Calender is an important equipment for artificial leather production. At present, the main material after filtering in the filter is transported to the calender through a four-roller main material conveyor. The waste material (commonly known as hot ear material) generated by the calender during the calendering operation contains a lot of impurities. For reuse, the hot ear material needs to be transported to the filter and mixed with the main material, and then filtered again and calendered again. The conveyor needs to be rearranged to convey the hot ear material to the filter, and the existing four-roller main material conveyor has a complex structure, occupies a large space, and has a large heat loss during the conveying process. Therefore, a compact and small composite conveyor is designed to convey the main material to the calender, and at the same time, the hot ear material generated by the calender is reversely transported to the filter, which has good thermal insulation performance and can achieve multiple goals at one stroke. Utility Model Content
[0003] The utility model is to solve the above technical problems and provide a calendered artificial leather composite conveyor which has compact structure, small volume, good heat preservation performance and can convey in both directions.
[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a calendered artificial leather composite conveyor, comprising a frame and a motor reducer, the frame is provided with a left mounting shaft and a right mounting shaft both horizontally arranged along the front and rear directions, the motor reducer is connected to the left mounting shaft or the right mounting shaft through a chain transmission mechanism or a belt transmission mechanism, the left mounting shaft is provided with two left sprockets arranged at intervals front and back, the right mounting shaft is provided with two right sprockets arranged at intervals front and back, the front left sprocket and the front right sprocket are driven by a front chain, the rear left sprocket and the rear right sprocket are driven by a rear chain, the rear side of the front chain and the front side of the rear chain are connected by a number of evenly arranged conveying rods, a guide roller is rotatably provided in the middle of each conveying rod, the outer diameter of the guide roller gradually becomes thicker from the middle to the front and rear ends, and the frame is provided with a heat preservation and heat insulation cover covering the left sprocket, the right sprocket, the front chain and the rear chain.
[0005] Each conveying rod includes a front ear plate fixedly connected to the rear side of the front chain and a rear ear plate fixedly connected to the front side of the rear chain. A guide rod is provided between the front ear plate and the rear ear plate. The front and rear ends of the guide rod are flattened into a planar structure and are fixedly connected to the front ear plate and the rear ear plate by bolts.
[0006] A through hole that is transparent front and back is opened in the center of the guide roller, and the guide rod is inserted in the through hole. A bearing is provided at both ends of the inner circle of the guide roller and is rotatably connected to the guide rod. A limit sleeve is installed on the guide rod at the front and rear ends of the guide roller. A top screw is threaded in the radial direction on the limit sleeve, and the inner end of the top screw presses against the outer circle of the guide rod.
[0007] A first material guide wheel is vertically arranged on the upper part of the frame adjacent to the left sprocket wheel.
[0008] A second guide wheel is vertically arranged on the right side of the lower part of the left sprocket on the frame, and a third guide wheel is vertically arranged on the left side of the lower part of the right sprocket on the frame. The second guide wheel is located at the front side of the front chain, and the third guide wheel is located at the rear side of the rear chain.
[0009] The left end of the thermal insulation cover is bent and extended upward, and the right end of the thermal insulation cover is bent and extended downward.
[0010] The above technical solution is adopted, and the utility model is arranged on the right side of the calender and the left side of the filter. The working process of the utility model is as follows: the motor reducer drives the left mounting shaft or the right mounting shaft, and then drives the front chain and the rear chain to rotate, and the upper half of the front chain and the rear chain moves from right to left, and the lower half of the front chain and the rear chain moves from left to right. The main material (continuous strip with a circular cross section) after being filtered by the filter enters the heat insulation cover from the bottom of the right sprocket upward, first passes through the guide roller on the right side of the right sprocket, and then moves upward along the arc groove in the middle of the guide roller and then moves to the left following the guide rod. When it moves to the first guide wheel adjacent to the main material, the main material leaves the guide roller forward or backward, and enters the calender under the guidance of the first guide wheel. At the same time, the waste materials (two hot ear materials) generated by the calender in the process of calendering the main material are discharged from the lower part. The two hot ear materials enter the guide rollers on the upper part of the lower half of the front chain and the rear chain from the second guide wheel on the left, and move to the right along the arc groove in the middle of the guide roller. When moving to the third guide wheel, the hot ear materials leave the guide roller backwards and enter the filter under the guidance of the third guide wheel.
[0011] The functions of each component or structure in the utility model are as follows:
[0012] (1) Since the speed of the upper half of the front chain and the rear chain conveying to the left is equal to the speed of the lower half conveying to the right, but the speed of producing the hot lug material is greater than the feeding speed of the main material to the calender, a self-rotating guide roller is set on the guide rod. When the hot lug material is conveyed from left to right, the friction between the hot lug material and the guide roller can drive the guide roller to rotate on the guide rod, thereby compensating for the relative speed difference between the hot lug material and the main material.
[0013] (2) Since the main material has a high temperature after passing through the filter, and the waste material (hot ear material) generated by the calender after the calendering operation also has a high temperature, the hot ear material is conveyed to the filter in the reverse direction while the main material is conveyed by the same conveyor. By setting up a heat-insulating cover, not only can dust be prevented from adhering to the main material and the hot ear material, but also the heat loss of the main material and the hot ear material during the conveying process can be reduced, thereby reducing the energy consumption of the calender and the filter.
[0014] (3) The conveying rod adopts a method in which the front and rear ends of the guide rod are connected to the front ear plate and the rear ear plate respectively through bolt assemblies, which facilitates the installation of the guide roller and the limit sleeve on the guide rod. Both ends of the inner circle of the guide roller are rotatably connected to the guide rod through bearings. The limit sleeve is used to limit the axial position of the bearing on the guide rod. The limit sleeve is fixedly connected to the guide rod through a top screw, which is convenient for disassembly and assembly.
[0015] (4) The first guide wheel is used to change the direction of the main material entering the calender; the second guide wheel is used to change the direction of the hot lug material entering the arc groove on the guide roller; the third guide wheel is used to change the direction of the hot lug material entering the feed port of the filter.
[0016] In summary, the utility model has a scientific principle and only uses one conveyor to realize the feeding of the main material to the calender, and at the same time realizes the return and transportation of the hot ear material to the filter. It has a compact structure, occupies a small volume, has small heat energy loss, and reduces the energy consumption of the calender and the filter. BRIEF DESCRIPTION OF THE DRAWINGS
