In actual production, in order to control the overall particle size of calcium master batch and separate impurities, a vibrating screen is usually used to perform vibrating screening treatment on the calcium master batch after production. During the screening process, the surface of the calcium master batch is wrapped with a layer of plastic after high-temperature melting and mixing of calcium carbonate, plastic carriers and additives.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0019] EMBODIMENT Please refer to Figures 1 to 3The utility model provides a kind of calcium master batch processing screening machine, including equipment main body 1, the front end surface of the equipment main body 1 is fixedly connected with control center 10, control center 10 is provided with driving motor 11, driving motor 11 is fixedly connected at the top of equipment main body 1 and the rear end output of driving motor 11 penetrates equipment main body 1 and extends to the inside of equipment main body 1, bottom plate assembly 2 is rotatably connected in equipment main body 1, the top front end and rear end of bottom plate assembly 2 are fixedly connected with connecting piece 25, screening assembly 3 is slidably connected between the two connecting pieces 25, the extension part of the output of driving motor 11 is fixedly connected with resonance assembly, the other end of resonance assembly is fixedly connected at the front end surface of screening assembly 3, mass sensor is fixedly connected in screening assembly 3, and mass sensor and driving motor 11 are electrically connected with control center 10; In actual production, in order to control the overall particle size of calcium master batch and separate impurities, a vibrating screen is usually used to vibrate and screen the calcium master batch after production. During the screening process, the surface of the calcium master batch is wrapped with a layer of plastic after high-temperature melting and mixing of calcium carbonate, plastic carrier and additives. During the conveying process, the plastic and the pipe wall of the conveying pipe 221 slide and rub with a large area of surface-to-surface contact, which is prone to static electricity. The calcium master batch has a large contact area with the inner wall of the conveying pipe 221, and the "contact-separation" movement of static electricity is generated. Although the contact frequency with the conveying pipe 221 is small, the area is large each time. After the generation of static electricity, the outer layer of plastic is adhered to each other, so that the device is prone to mutual adhesion of the calcium master batch after unloading. When a batch of calcium master batch is screened by the vibrating screen, the total mass of the calcium master batch is not the same. The existing equipment keeps the same frequency during continuous operation when the vibrating screen is started. When the calcium master batch is adhered in the storage tank, the total amount of calcium master batch unloaded to the vibrating screen surface at a time is small, and the device keeps the same frequency to operate, which is easy to cause energy waste. When the calcium master batch is adhered and unloaded together, the device keeps the same frequency to operate, which is difficult to quickly screen the calcium master batch, prolongs the screening time of the calcium master batch, and increases the energy consumption; The application discloses a screening machine for calcium master batch processing, which is characterized in that calcium master batch materials are conveyed to the top end of a screening assembly 3, a mass sensor detects the mass of the calcium master batch materials loaded to the screening assembly 3 and uploads the detection result to a control center 10, the control center 10 analyzes the detection data and controls a driving motor 11 to operate, the driving motor 11 operates to drive the screening assembly 3 to vibrate in two connecting pieces 25 through a resonance assembly, at this time, the vibration of the screening assembly 3 has little effect on a bottom plate assembly 2, when the mass of the calcium master batch materials is low, the driving motor 11 keeps a low rotating frequency, so that the vibration frequency of the screening assembly 3 is low enough to screen the calcium master batch materials, when the mass of the calcium master batch materials is large, the driving motor 11 increases the rotating frequency, so that the vibration frequency of the screening assembly 3 is large, thereby quickly screening the calcium master batch materials, the screened calcium master batch materials fall to the bottom plate assembly 2 for collection, the energy-saving effect of the screening machine is improved, and the screening machine is convenient to use. Please refer to Figures 3 to 5 Further in the above description, the bottom plate assembly 2 comprises four rotating pieces 20, two rotating pieces 20 at one end are internally rotatably connected with a first supporting rod 21, two rotating pieces 20 at the other end are internally rotatably connected with a second supporting rod 23, the bottom of the first supporting rod 21 is provided with a first adjusting chamber 22, the first supporting rod 21 penetrates through the first adjusting chamber 22 and extends to the inside of the first adjusting chamber 22, a first piston plate 210 is fixedly connected to the extended part of the first supporting rod 21, two first elastic pieces 220 are fixedly connected to the bottom of the first piston plate 210 and the other ends of the two first elastic pieces 220 are fixedly connected to the inner wall at the bottom side of the first adjusting chamber 22, the inside of the first adjusting chamber 22 is loaded with a liquid solvent, the bottom of the second supporting rod 23 is provided with a second adjusting chamber 24, the second supporting rod 23 penetrates through the second adjusting chamber 24 and extends to the inside of the second adjusting chamber 24, a second piston plate 230 is fixedly connected to the extended part of the second supporting rod 23, two second elastic pieces 240 are fixedly connected to the top of the second piston plate 230 and the other ends of the second elastic pieces 240 are fixedly connected to the inner wall at the top side of the second adjusting chamber 24, and a conveying pipe 221 is fixedly connected between the first adjusting chamber 22 and the second adjusting chamber 24; When the calcium master batch raw material is poured at the screening assembly 3 in the above step, the screening assembly 3 is initially connected with a certain margin in the two connectors 25, and the single quality of the calcium master batch material cannot cause great impact on the bottom plate assembly 2 after being buffered by the first elastic member 220 and the second elastic member 240. When the single conveying calcium master batch material has large quality, the weight at one end of the screening assembly 3 increases, so that the stress at one end of the bottom plate assembly 2 increases, and the two rotating members 20 at one end are pressed towards the first support rod 21. The first support rod 21 is affected by the pressure and drives the first piston plate 210 to move downward in the first adjusting chamber 22. The first elastic member 220 is compressed and elastically deformed. The downward movement of the first piston plate 210 increases the internal gas pressure of the first adjusting chamber 22. The increased internal gas pressure of the first adjusting chamber 22 delivers the liquid solvent inside to the second adjusting chamber 24 through the conveying pipe 221. The internal gas pressure of the second adjusting chamber 24 increases after obtaining the liquid solvent inside. At this time, the second piston plate 230 in the second adjusting chamber 24 is affected by the pressure and moves upward. The upward movement of the second piston plate 230 drives the other end of the bottom plate assembly 2 to move upward through the second support rod 23 and makes the bottom plate assembly 2 change the angle. As the quality of the single conveying calcium master batch material increases, the rotation angle of the bottom plate assembly 2 and the screening assembly 3 tends to be horizontal, and the falling speed of the calcium master batch material under the influence of gravity is also lower. The longer the calcium master batch material stays in the screening assembly 3, the better the screening quality of the screening assembly 3 for the calcium master batch material. The device does not need to reciprocate and consume energy to screen the calcium master batch material multiple times, which improves the screening quality and energy-saving effect of the device and is convenient for users to use. Please refer to Figures 3 to 5Further in the foregoing description, the bottom plate assembly 2 further comprises two first linear drive assemblies 26 fixedly connected at the front end and rear end surfaces of the bottom plate assembly 2 respectively, and the first linear drive assembly 26 is specifically an electric push rod. The other end output of the first linear drive assembly 26 is fixedly connected with a first output rod 260, and the other end of the first output rod 260 is fixedly connected with a fixed plate 261. The end close to the symmetry plane of each fixed plate 261 is provided with two slide rods 262, and the end close to the symmetry plane of the fixed plate 261 is provided with a sliding groove 263 at the top side. The slide rod 262 at the top is slidingly connected in the sliding groove 263, and the slide rod 262 at the bottom is fixedly connected at the bottom side of the end close to the symmetry plane of the fixed plate 261. The slide rod 262 at the top penetrates through the screening assembly 3 and extends to the inside of the screening assembly 3, and the two slide rods 262 at the bottom penetrate through the bottom plate assembly 2 and extend to the inside of the bottom plate assembly 2. The extension plates 4 are fixedly connected between the extension portions of the two slide rods 262 at the top and the extension portions of the two slide rods 262 at the bottom, and the extension plates 4 at the top and the bottom are respectively matched with the screening assembly 3 and the bottom plate assembly 2 in shape and size. When the mass of the single-time delivered calcium master batch material is large, and the screening assembly 3 and the bottom plate assembly 2 are angularly rotated in the above-mentioned step, the control center 10 is opened to open the two first linear drive assemblies 26. The first linear drive assembly 26 is opened to drive the two fixed plates 261 to move through the first output rod 260. The two fixed plates 261 are moved to drive the two extension plates 4 to respectively protrude from the screening assembly 3 and the bottom plate assembly 2 and move. At this time, the protrusion of the extension plate 4 can further prolong the residence time of the calcium master batch material in the screening assembly 3, and further improve the screening effect of the device, which is convenient for users to use. Please refer to Figures 5 to 6 Further in the foregoing description, the screening assembly 3 comprises two side frames 30 slidingly connected at the front side and rear side surfaces of the top of the screening assembly 3 respectively.

When the bottom plate assembly 2 and the screening assembly 3 are in the angle adjusting state, at this time, the angle change of the bottom plate assembly 2 and the screening assembly 3 causes the calcium master batch material at one end of the screening assembly 3 to gradually accumulate, at this time, the control center 10 is opened to start the second linear drive assembly 34, the second linear drive assembly 34 is started to drive the frontmost guide plate 35 to move away from the accommodating groove through the second output rod 340, the frontmost guide plate 35 moves through the plurality of through rods 350 to drive the plurality of remaining guide plates 35 to move together, at this time, the plurality of guide plates 35 block the gap between the plurality of guide frames 330 after being separated from the accommodating groove, the control center 10 is opened to start the electric turntable 32, the electric turntable 32 is started to drive the guide assembly 33 to rotate counterclockwise as a whole through the rotating rod 320 and the front end guide frame 330, at this time, the closed space composed of the plurality of guide frames 330 and the plurality of guide plates 35 covers the calcium master batch material, at this time, the closed space can be moved to drive the calcium master batch material to move on the surface of the screening assembly 3, so as to uniformly distribute the calcium master batch material on the surface of the screening assembly 3, improve the screening quality and energy saving effect of the device, facilitate the use of the user;
