Description

Technical Field

[0001] This utility model relates to the field of water drilling technology, and in particular to a water drilling screening device. Background Technology

[0002] In the rhinestone manufacturing industry, the particle size and uniformity of rhinestones play a crucial role in the quality and market value of the finished product. With the widespread application of rhinestones in jewelry, clothing accessories, and handicrafts, the market demand for both quality and quantity of rhinestones is increasing daily. During the production process, due to the characteristics of the manufacturing process, the particle size of rhinestones will vary within a certain range. To meet the precise particle size requirements of different industries and products, efficient and accurate screening has become an indispensable and important part of the rhinestone production process. Therefore, a rhinestone screening device is designed.

[0003] The existing water drill screening devices have a relatively simple vibration mode, which results in a large number of water drills not passing through the appropriate screen aperture due to insufficient vibration. This leads to low screening efficiency and incomplete screening. Furthermore, the feeding amount cannot be accurately adjusted according to the operating status of the screening equipment. Too much feeding can easily cause screen blockage and interrupt the screening operation; too little feeding leads to insufficient utilization of the screening equipment, a significant reduction in screening efficiency, and difficulty in ensuring the stability and continuity of the screening process, thus affecting the overall production rhythm.

[0004] This disclosure relates to a water-drill screening device to solve the technical problems mentioned in the background art.

[0005] In a first aspect, this disclosure provides a water drill screening device, specifically including: a screening box;

[0006] The screening box has four sets of supports installed at its lower end. Each of the four sets of supports has a hinge seat installed below it. A spring is fixed between the hinge seat and the support. A base plate is installed below the screening box. Two sets of front support columns are fixed on the base plate. The two sets of front support columns are connected to two sets of hinge seats near the left end of the screening box by pins. An mounting plate is installed on the base plate. Four sets of support plates are bolted to the lower end of the mounting plate. The lower ends of the four sets of support plates are bolted to the base plate. A rotating rod is installed on the base plate by bearings. Cams are fixed to the front and rear ends of the rotating rod. Two sets of rotatable swing arms are installed at the lower end of the mounting plate. Contact shafts are fixed on the two sets of swing arms. The two sets of contact shafts are in contact with the two sets of cams respectively.

[0007] In at least some embodiments,

[0008] Both sets of swing arms are provided with sliding grooves, and two sets of rear support columns slide on the mounting plate. Each set of rear support columns is secured with a mating seat by bolts, and the two sets of mating seats move within the sliding grooves on the two sets of swing arms respectively.

[0009] In at least some embodiments,

[0010] The upper ends of both sets of rear support columns are connected to two sets of hinge seats near the right side of the screening box via pins. A gearbox is bolted to the base plate. A worm gear is installed inside the gearbox. The shaft of the worm gear is connected to the rotating rod. A worm is installed inside the gearbox via bearings. The worm meshes with the worm gear. A No. 1 motor is bolted to the gearbox. The output shaft of the No. 1 motor is connected to the worm.

[0011] In at least some embodiments,

[0012] The inner walls of the front and rear ends of the screening box are provided with a No. 1 installation slot and a No. 2 installation slot. Both the No. 1 installation slot and the No. 2 installation slot are designed to be inclined, and the height of the right side is higher than that of the left side. The No. 1 screen plate and the No. 2 screen plate are installed in the No. 1 installation slot and the No. 2 installation slot, respectively.

[0013] In at least some embodiments,

[0014] The left side of the screening box is equipped with a No. 1 feeding hopper and a No. 2 feeding hopper, which are respectively located on the left side of the No. 1 screen plate and the No. 2 screen plate.

[0015] In at least some embodiments,

[0016] The screening box has a discharge port at its lower end and a frame is bolted to its upper end. A baffle slides inside the frame and has threaded holes.

[0019] This utility model provides a water-based diamond screening device, which has the following beneficial effects:

[0020] In this invention, a primary electric motor drives a worm gear transmission, which in turn rotates the rotating rod and cam, causing the swing arm to swing rhythmically. This swing is transmitted to the screening box via the rear support column. Combined with the spring connection between the screening box and the bottom plate, this provides a stable and continuous vibration effect for the screening box. Compared with traditional screening devices, its vibration frequency and amplitude can be precisely controlled by adjusting the motor speed and the worm gear transmission ratio, greatly improving screening efficiency and ensuring that the water drill can be fully and evenly screened on the screen plate, reducing the phenomenon of incomplete screening caused by unstable vibration.

[0021] Furthermore, in this invention, the No. 1 and No. 2 mounting slots provided on the inner wall of the screening box can respectively install No. 1 and No. 2 screen plates with different aperture specifications. This enables the device to perform screening operations on water drills with multiple particle size ranges at one time. Water drills of different specifications can be screened through the corresponding screen plates and discharged through their respective discharge hoppers, achieving efficient grading and screening.

[0022] Furthermore, in this invention, the feed hopper installed on the frame facilitates the insertion of the water drill, and the screw driven by the No. 2 motor can precisely control the lifting and lowering of the baffle, thereby flexibly adjusting the size of the feed inlet and achieving precise control of the feed flow. This design avoids problems such as reduced screening efficiency or screen blockage caused by too much or too little feed, ensuring the stable operation of the screening process and improving the controllability and stability of the entire screening operation.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Example 1: Please refer to Figures 1 to 7 :

[0038] This utility model proposes a water drill screening device, including: screening box 1;

[0039] Four sets of supports 11 are installed at the lower end of the screening box 1. Each of the four sets of supports 11 has a hinge seat 12 installed below it. A spring 121 is fixed between the hinge seat 12 and the support 11. A base plate 2 is installed at the lower end of the screening box 1. Two sets of front support columns 21 are fixed on the base plate 2. The two sets of front support columns 21 are respectively connected to the two sets of hinge seats 12 near the left end of the screening box 1 by pins. An mounting plate 22 is installed on the base plate 2. Four sets of support plates 221 are installed at the lower end of the mounting plate 22 by bolts. The lower ends of the four sets of support plates 221 are installed on the base plate 2 by bolts. A rotating rod 222 is installed on the base plate 2 by bearings. Cams 2221 are fixed at both the front and rear ends of the rotating rod 222. Two sets of rotatable swing arms 223 are installed at the lower end of the mounting plate 22. Contact shafts 2231 are fixed on both sets of swing arms 223. The two sets of contact shafts 2231 are in contact with the two sets of cams 2221 respectively.

[0040] In this embodiment of the disclosure,

[0041] Both sets of swing arms 223 are provided with sliding grooves. Two sets of rear support columns 224 slide on the mounting plate 22. Each set of rear support columns 224 is bolted with a mating seat 2241. The two sets of mating seats 2241 move within the sliding grooves on the two sets of swing arms 223. The upper ends of the two sets of rear support columns 224 are connected to two sets of hinge seats 12 near the right side of the screening box 1 via pins. A gearbox 23 is bolted to the base plate 2. A worm gear 231 is installed inside the gearbox 23. The shaft of the worm gear 231 is connected to the rotating rod 222. A worm 232 is installed inside the gearbox 23 via bearings. The worm 232 meshes with the worm gear 231. Furthermore, a No. 1 motor 233 is bolted onto the gearbox 23. The output shaft of the No. 1 motor 233 is connected to the worm gear 232. Its function is to run the No. 1 motor 233 to make the rotating rod 222 rotate smoothly. The cam 2221 fixed at the front and rear ends of the rotating rod 222 rotates accordingly. When the cam 2221 rotates, it periodically pushes the contact shaft 2231 on the swing arm 223, causing the swing arm 223 to swing regularly around its rotation point. The swing of the swing arm 223 is transmitted to the screening box 1 through the rear support 224. Combined with the spring 121 connecting the screening box 1 and the bottom plate 2, the screening box 1 can generate stable and continuous vibration.

[0042] Example 2, based on Example 1,

[0043] The inner walls of both the front and rear ends of the screening box 1 are provided with a first mounting groove 131 and a second mounting groove 132. Both the first mounting groove 131 and the second mounting groove 132 are designed with an incline, and the right side is higher than the left. A first screen plate 1311 and a second screen plate 1321 are respectively installed in the first mounting groove 131 and the second mounting groove 132. A first discharge hopper 1312 and a second discharge hopper 1322 are respectively installed on the left side of the screening box 1 via bolts. The first discharge hopper 1312 and the second discharge hopper 1322... 22 are located on the left side of screen plate 1311 and screen plate 1321 respectively. Their function is as follows: the first hopper 1312 and the second hopper 1322 installed on the left side of the screening box 1 correspond to screen plate 1311 and screen plate 1321 respectively. The water drills that pass through screen plate 1311 will fall into the first hopper 1312. Similarly, the water drills that pass through screen plate 1321 will fall into the second hopper 1322. The setting of the hoppers realizes the classification and collection of water drills of different particle sizes.

[0044] Example 3, based on Examples 1 and 2,

[0045] A discharge port is provided at the lower end of the screening box 1. A frame 14 is bolted to the upper end of the screening box 1. A baffle 141 slides inside the frame 14. The baffle 141 has a threaded hole. A lead screw 142 is mounted on the frame 14 via a bearing. The lead screw 142 is threaded into the threaded hole on the baffle 141. A gearbox 143 is bolted to the frame 14. The output shaft of the gearbox 143 is connected to the lead screw 142. A second motor 1431 is bolted to the gearbox 143. A feed hopper 144 is bolted to the frame 14. Furthermore, vibrators 13 are bolted to both the front and rear ends of the screening box 1. Their function is as follows: the discharge port at the lower end of the screening box 1 provides a discharge channel for smaller diameter water drills or other impurities. When the No. 2 motor 1431 is started, its power is transmitted to the lead screw 142 after being accelerated or decelerated through the gearbox 143. When the lead screw 142 rotates, due to the threaded engagement with the threaded hole on the baffle 141, the baffle 141 will slide up and down in the frame 14, thereby changing the size of the feed inlet. The vibrators 13 installed at the front and rear ends of the screening box 1 provide additional auxiliary vibration for the screening process.

[0046] The working principle of this embodiment: When this water drill screening device is working, firstly, the second motor 1431 is turned on. Its output power is adjusted by the gearbox 143, and then drives the lead screw 142 to rotate. The lead screw 142 is threadedly engaged with the baffle 141, so that the baffle 141 slides up and down in the frame 14, thereby adjusting the size of the feed inlet at the bottom of the feed hopper 144 and introducing an appropriate amount of water drills to be screened into the screening box 1. At the same time, the first motor 233 is started, and its output shaft drives the worm 232 to rotate. The worm 232 drives the worm wheel 231 meshing with it to rotate. The rotating shaft of the worm wheel 231 drives the rotating rod 222 to rotate. The cams 2221 at both ends of the rotating rod 222 rotate accordingly. The cams 2221 periodically push the contact shaft 2231 on the swing arm 223, causing the swing arm 223 to swing. This swing is transmitted to the screening box 1 through the rear support 224, and then combined with... The buffering and auxiliary effect of the spring 121 between the screening box 1 and the bottom plate 2 enables the screening box 1 to generate stable and continuous vibration. During the vibration of the screening box 1, the water drills inside the box jump and move on the screen plate. Due to the inclined design of the first mounting groove 131 and the second mounting groove 132 with the right side higher than the left side, the water drills will naturally move to the lower left while vibrating. When water drills of different particle sizes pass through the first screen plate 1311 and the second screen plate 1321, the water drills that match the aperture of the screen plate pass through the screen and fall into the corresponding first discharge hopper 1312 and second discharge hopper 1322 respectively. In addition, the vibrator 13 installed at the front and rear ends of the screening box 1 generates auxiliary vibration, making the movement of the water drills on the screen plate more complex and diverse, effectively preventing the water drills from sticking, overlapping or getting stuck on the screen, and further improving the screening accuracy. Smaller particle sizes of water drills or impurities are discharged from the discharge port at the bottom of the screening box 1.
