[0003] The current quartz plate unloading equipment includes a mixing box, a mounting groove, a baffle, a hopper and a tilting mechanism. When discharging is required, the tilting mechanism will push the left side of the mixing box to lift up so that the raw materials in the mixing box can be poured toward the mounting groove. At this time, the baffle can be driven to move through the lifting mechanism so that the mounting groove is no longer closed, and the raw materials can be discharged into the hopper and discharged outward through the hopper to the feeding conveyor belt.

For a quartz plate having multiple unloading and laying areas (i.e., multiple areas divided along the width direction of the quartz plate), the equipment cannot unload in a designated area (such as a single or multiple areas) to lay the corresponding plate area, and cannot ultimately form the desired plate stripes, thereby failing to meet the processing requirements of different stripe effects of the quartz plate, and has low applicability.

[0020] A plurality of material distribution mechanisms 5 are provided at the lower part of the material distribution box 3, and the plurality of material distribution mechanisms 5 are used to divide the discharge port 32 of the material distribution box 3 into a plurality of discharge areas 33, so that the raw materials can be discharged from a single, multiple or all areas to the conveying surface of the feeding conveyor belt below; through the conveying work of the feeding conveyor belt, the required raw material layer can be continuously laid on the conveying surface and transported to the subsequent processing procedure; wherein, the laid material layer can be laid in all areas through a single or multiple weighing and dividing equipment to form a processing material layer of quartz plate of corresponding width.

[0021] The material dividing mechanism 5 includes a material dividing drive component 51 and a material dividing plate 52. The material dividing drive component 51 is connected to the material dividing plate 52 and is used to drive the material dividing plate 52 to open or close the corresponding material discharging area 33. The corresponding material discharging area 33 can be opened by controlling the designated material dividing drive component 51, so that the raw materials are discharged to the area to form the required material discharging laying area. The set material dividing plate 52 can limit the raw materials on the conveying surface, so that the raw materials form a material layer of corresponding thickness, thereby meeting the material discharging and processing requirements of different areas of the quartz plate, and then ensuring the optimal placement of the material so that the finally formed quartz plate can replicate the multi-shadow areas of the natural stone background, with high adaptability and good aesthetics.

[0022] The lifting drive end of the lifting adjustment mechanism 4 is connected to the material distribution box 3, and is used to drive the material distribution box 3 and the material distribution plate 52 to do lifting movement, so as to adjust the height position of the material distribution box 3 and the material distribution plate 52. That is, the distance between the bottom end surface of the material distribution plate 52 and the conveying surface of the feeding conveyor belt below is adjusted, so as to adjust the thickness of the laid material layer accordingly, ensure that the raw materials are evenly distributed and not too thick, avoid excessive accumulation of raw materials to form large blocks, and affect the subsequent processing effect. In addition, the overall function of the device is diverse and the structure is simple.

[0023] Preferably, the plurality of material dividing mechanisms 5 are used to equally divide the material outlet 32 ​​of the material dividing box 3 into a plurality of material discharging areas 33 , but this is not limiting and can be adjusted to a non-equal division method according to actual needs.

[0024] In this embodiment, the device includes four material distribution mechanisms 5, which can divide the discharge port 32 of the material distribution box 3 into four discharge areas 33, but this is not a limitation, and the number of equal divisions can be adjusted according to actual conditions. Figure 7 As shown, the feeding conveyor belt is provided with a weighing and distributing device of 4 equal parts, a weighing and distributing device of 6 equal parts and a weighing and distributing device of 8 equal parts. For example, the weighing and distributing device of 4 equal parts includes 4 equal distributing mechanisms and has four equal discharging areas. The user can control multiple weighing and distributing devices to open different discharging areas according to production needs, so that the raw materials of corresponding colors are discharged to the corresponding areas, and together form the width area of ​​the production plate, so as to obtain striped plates with different interval colors to meet the user's striped plate needs.

[0025] Furthermore, mounting frames 34 are installed on both sides of the material distribution box 3, and mounting plates 35 are provided at the bottom of the mounting frames 34. A material distribution drive assembly 51 is provided on the mounting plates 35, and the material distribution plates 52 are sealed against the bottom of the material distribution box 3 to seal the raw materials in the material distribution box 3 and prevent the raw materials from leaking.

By simultaneously controlling the material distribution plates 52 on both sides to gradually open the corresponding material discharging area 33 in a manner of moving away from each other, the material can be evenly discharged, and the material can be evenly diffused from the middle to both sides, thereby improving the discharging and raw material laying effects.

[0026] The material distribution drive assembly 51 includes a material distribution pusher 53 and a guide plate 54, wherein the guide plates 54 are respectively arranged on both sides of the lower part of the mounting plate 35; a connecting mounting plate 55 is arranged between the guide plates 54 on both sides, and the material distribution pusher 53 is installed on the connecting mounting plate 55; a slide groove seat 56 corresponding to the guide plate 54 is respectively arranged on both sides of one end of the material distribution plate 52, wherein the slide groove seat 56 is clamped with the guide plate 54 and the two are slidably connected, and the driving rod of the material distribution pusher 53 is connected to the connecting mounting seat 57 on the material distribution plate 52. The material distribution pusher 53 can drive the material distribution plate 52 to move horizontally back and forth along the horizontal guide direction of the guide plate 54, so that the material distribution plates 52 on both sides are simultaneously moved away from or close to each other, so as to open or close the corresponding material discharging area 33, and realize the material discharging or non-discharging work.

[0027] Preferably, the material distribution pushing device 53 is preferably a pushing cylinder or a pushing electric cylinder, but this is not limited to this.

When the gravity of the raw materials acts on all the material distribution plates 52, since the mounting plate 35 is connected to the material distribution mechanism 5, and the mounting plate 35 is connected to the weighing detection device 61, the gravity of the raw materials indirectly acts on the weighing detection device 61 to realize the weighing detection function. Among them, the weighing detection device 61 is preferably a tension and pressure sensor, but is not limited thereto.

[0029] In actual use, when the sum or average of the detection data obtained by the multiple groups of weighing detection components 6 on the left and right sides of the material distribution box is greater than or equal to the preset weight threshold for stopping feeding, the feeding can be stopped, and when the sum or average of the obtained detection data is less than or equal to the preset weight threshold for starting feeding, the feeding can be started. In this way, the automatic feeding control of the equipment can be realized, the automation level of the equipment can be improved, and the labor cost can be reduced. Secondly, after the equipment discharges the material, it can also be processed according to the detection data of the weighing detection component 6 to determine the weight of each discharge, so as to facilitate the staff to monitor the operation of the equipment.

[0030] Preferably, if Figure 4 and Figure 6 As shown, a discharge guide portion 36 is provided at the bottom of one side panel of the distribution box 3, and the discharge guide portion 36 extends downward along the height direction of the distribution box 6 and extends in the opposite direction of the conveying direction of the feeding conveyor belt, and a guide portion 521 is provided at one end of the distribution plate 52 away from the distribution drive assembly 51, and the guide portion 521 extends downward along the height direction of the distribution plate 52 and extends along the opening direction of the distribution plate 52. When discharging, the distribution plates 52 on both sides move away from each other, and the guide starting point of the guide portion 521 of the distribution plate 52 on the left side is exactly connected to the guide end point of the discharge guide portion 36 to form a total guide portion, so as to guide the raw materials to flow quickly and evenly from the guiding direction of the total guide portion to the conveying surface, which can reduce the discharging resistance, improve the discharging efficiency and the discharging uniformity, and then quickly transport it to the subsequent processing steps through the feeding conveyor belt to improve the processing efficiency. Preferably, the discharge guide portion 36 is a circular arc guide portion, but the present invention is not limited thereto.

[0031] Preferably, the guide portion 521 is an inclined guide portion, but the present invention is not limited thereto.

[0032] In order to adjust the height of the dividing plate 52, Figure 1 , Figure 3 and Figure 5 As shown, the lifting adjustment mechanism 4 includes an upper fixed seat 41, a lower fixed seat 42, a lifting drive device 43 and a guide rod 44; one end of the lower fixed seat 42 is installed on the machine body, and the other end of the lower fixed seat 42 is installed with the lifting drive device 43, the driving rod of the lifting drive device 43 is connected to the upper fixed seat 41, and one end of the upper fixed seat 41 is installed on the material distribution box 3; the guide rods 44 are respectively located on both sides of the lifting drive device 43, one end of the guide rod 44 is connected to the upper fixed seat 41, and the other end passes through the guide sleeve 45 of the lower fixed seat 42 and is connected to the guide connecting plate 46 below the lower fixed seat 42. When the lifting drive device 43 drives the upper fixed seat 41 to move, it can drive the material distribution box 3 and the material distribution plate 52 to move synchronously, realize the height adjustment of the material distribution plate 52, and thus adjust the thickness of the laid material layer; the guide rods 44 on both sides play a guiding role, so that the lifting work can move stably along the specified lifting direction, ensuring the stable height adjustment work.

[0033] Preferably, the lifting drive device 43 is preferably a lifting electric cylinder, but this is not limited to this.

[0034] In order to realize the feeding work, Figure 1 As shown, the feeding mechanism 2 includes a horizontal moving mechanism 21 and a feeding hopper 22. When feeding, the horizontal moving mechanism 21 drives the feeding hopper 22 to move from the initial position to the position directly above the distribution box 3, so as to convey the raw materials input by the external feeding equipment to the distribution box 3 below through the feeding hopper 22, so as to prepare for the subsequent distribution. By setting the conical feeding hopper 22, the flow speed of the raw materials in the hopper is made more uniform, the blockage of the raw materials is reduced, and the stable transportation of the raw materials is achieved. When the feeding is completed, the horizontal moving mechanism 21 drives the feeding hopper 22 to reset and stop the feeding work.

[0035] Furthermore, the horizontal moving mechanism 21 includes a moving motor device 211, a driving wheel 212, a driven wheel 213, a synchronous belt 214 and a horizontal guide rail 215, and the horizontal guide rail 215 is arranged on both sides of the machine body; the feed hopper 22 is located between the horizontal guide rails 215 on both sides, and horizontal frames 221 are respectively provided at both ends of the feed hopper 22, and a plurality of sliding seats compatible with the horizontal guide rails 215 are arranged on the horizontal frames 221 at intervals, and the sliding seats are clamped with the horizontal guide rails 215 and the two are slidably connected so that the feed hopper 22 can move on the horizontal guide rails 215. The mobile motor device 211 and the driven wheel 213 are both installed on the same side of the machine body, that is, close to the horizontal guide rail 215 on one side, the mobile motor device 211 is connected to the driving wheel 212, and the driving wheel 212 is connected to the driven wheel 213 through a synchronous belt 214. A plurality of clamping parts 222 fixedly connected to the synchronous belt 214 are provided on the horizontal frame 221 at intervals. When the mobile motor device 211 drives the synchronous belt 214 to rotate, the clamping part 222 can drive the feed hopper 22 to move back and forth along the direction of the horizontal guide rail 215, so that the feed hopper 22 moves to the feeding position to feed and resets to wait for work.

[0036] Preferably, if Figure 1 As shown, accordion covers 7 are respectively provided at both ends of the horizontal guide rail 215 to protect the horizontal guide rail 215, reduce maintenance workload and improve equipment stability.

[0037] like Figure 8 As shown, the present invention also provides a control method for a weighing and dispensing device, which is applied to the above-mentioned weighing and dispensing device, comprising: S101, when feeding into the material distribution box, obtaining the raw material weight data and material distribution control data in the material distribution box in real time; It should be noted that when feeding is required, the feed hopper can be driven to move to the top of the material distribution box, and the external feeding equipment can be driven to feed the feed hopper, so that the feed hopper can evenly transport the input raw materials to the material distribution box. In this stage, after processing the detection data obtained by multiple weighing and detection side components, the raw material weight data can be obtained to improve the data detection accuracy; the material distribution control data is obtained through the program preset by the user, or through the data directly input by the user through the control terminal. Among them, the material distribution control data includes thickness adjustment data and material distribution area control data.

[0038] S102, when the raw material weight data is greater than or equal to a first preset weight preset threshold, stop feeding; It should be noted that, when during the feeding process, the raw material weight data is greater than or equal to the first preset weight preset threshold, it means that the feeding weight has reached the preset requirement. At this time, the external feeding equipment is controlled to stop working and the feeding hopper is driven to reset.

[0039] S103, controlling the lifting adjustment mechanism to drive the material distribution box and the material distribution plate to move to a specified height according to the thickness adjustment data; It should be noted that before the material distribution work is carried out, the central control console of the equipment can control the lifting and adjusting mechanism to drive the distribution box and the distribution plate to move to the specified height according to the thickness adjustment data, thereby realizing the laying of raw materials of corresponding thickness.

[0040] S104, comparing the material distribution area control data with the preset area library to obtain the required area control instructions; S105, controlling the corresponding material distribution mechanism 5 to operate according to the area control instruction to open the corresponding material discharging area.

[0041] It should be noted that after the required thickness of the material layer is adjusted, the required area control instructions can be obtained by comparing the material distribution area control data with the preset area library; according to the area control instructions, the material distribution mechanism of the specified area can be controlled to open the corresponding material discharging area to realize the material discharging work of the corresponding material discharging area. For example, among the four material discharging areas arranged in sequence, the first material discharging area, the first and second material discharging areas, the first and third material discharging areas or all areas can be opened, so as to realize the material laying work of the corresponding area.

[0042] Furthermore, the step after stopping feeding also includes: determining whether the raw material weight data is less than or equal to a second preset weight preset threshold value; if it is determined to be yes, stopping the material distribution work and re-performing the feeding work until the raw material weight data is greater than or equal to the first preset weight preset threshold value; if it is determined to be no, continuing the material distribution work.

[0043] It should be noted that when the raw material weight data is less than or equal to the second preset weight preset threshold, it means that the raw material in the material distribution box is too little and needs to be replenished. At this time, the material distribution work is stopped, all discharge areas are closed, and the feeding work is restarted until the raw material weight data is greater than or equal to the first preset weight preset threshold, and the material distribution work is restarted; when the raw material weight data is greater than the second preset weight preset threshold, it means that the raw material in the material distribution box is still sufficient, and the material distribution work can continue to ensure the stable operation of the material distribution work.

[0044] In summary, the present invention can adjust the height of the material distribution box and the material distribution plate through the lifting and adjusting mechanism, so as to adjust the distance between the bottom end surface of the material distribution plate and the conveying surface of the feeding conveyor belt below, and then adjust the thickness of the laid material layer to ensure that the raw materials are evenly distributed on the conveying surface. At the same time, a plurality of material distribution mechanisms are arranged at the discharge end of the material distribution box, and the material distribution port can be divided into a plurality of discharge areas. By controlling the designated material distribution mechanism, the corresponding discharge area can be opened, so that the raw materials are discharged to the area to form the required material discharging and laying area, which can meet the material discharging and processing requirements of different areas of the quartz plate, thereby ensuring the best placement of the material so that the finally formed quartz plate can replicate the multi-shadow area of ​​the natural stone background, with high adaptability, good aesthetics, and diverse functions and simple structure.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
