Description

Technical Field

[0001] This utility model relates to the field of grinding ball deburring technology, specifically to a grinding ball deburring device. Background Technology

[0002] Wear-resistant steel balls are classified according to their manufacturing process into grinding steel balls, forged steel balls, and cast steel balls. They are also classified according to their materials into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy balls, etc. Among them, bearing steel balls are important basic components in industry. Alloy steel balls are spherical iron alloy wear-resistant bodies made of carbon, chromium, manganese, molybdenum, etc., with carbon, chromium, manganese, molybdenum, etc. as the main added metal elements, and are produced through forging, spinning, rolling, and casting. They are the most important components of balls used in the crushing industry, mining, cement, etc.

[0003] The prior art patent publication number CN214025163U describes a surface deburring device for polishing steel balls. This patent includes a brittleness-reducing mechanism. Before deburring, the steel balls are cooled in liquid nitrogen, which brittles the burrs, thus enabling more efficient burr removal. The device includes a stirring mechanism and multiple grinding mechanisms fixedly installed in the working chamber. A large number of steel balls can be placed in the working chamber, and the stirring mechanism causes the steel balls to collide with each other and with the grinding wheel, achieving efficient burr removal. The device also features a novel screening mechanism that separates the steel balls from the removed burrs, improving the efficiency of steel ball recycling after processing.

[0004] Although the aforementioned patent utilizes a screening plate, which can separate the steel balls from the removed burrs as they roll on the screening plate, in practice, the screening plate is static and inclined. This not only makes it difficult to remove debris attached to the surface of the steel balls, but also causes the steel balls to roll too fast on the screening plate, resulting in insufficient screening of the steel balls. This necessitates secondary manual screening, increasing labor intensity. Utility Model Content

[0005] To solve the above-mentioned technical problems, a grinding ball deburring device is provided. This device solves the problem that in the prior art, the screening plate is static and inclined, which not only makes it difficult to remove the debris attached to the surface of the steel balls, but also causes the steel balls to roll too fast on the screening plate, resulting in insufficient screening of the steel balls and requiring secondary manual screening, which increases the labor intensity.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a grinding ball deburring device, including a novel screening mechanism;

[0007] The novel screening mechanism includes an inclined screening frame and a sieve plate fixed to the bottom inner side of the screening frame. A vibrator is installed on the side wall of the screening frame. Two lifting grooves are symmetrically opened on the sieve plate. An intermittent blocking part is provided in the lifting groove. The two sets of intermittent blocking parts are staggered and an intermittent driving part is provided between the two sets of intermittent blocking parts.

[0008] The intermittent barrier is a barrier plate that slides within the lifting groove.

[0009] Preferably, the intermittent drive unit includes a toothed plate fixed to the bottom end of the barrier plate, and a transmission rod is provided between the two toothed plates. The transmission rod is fastened with a gear that meshes with the toothed plate.

[0010] Preferably, mounting plates are vertically fixed on both the front and rear sides of the bottom end face of the screening frame, the transmission rod rotates laterally between the two mounting plates, and a forward and reverse motor is installed on the outer wall of one of the mounting plates. The output shaft of the forward and reverse motor rotates through the mounting plate and is fixedly connected to one end of the transmission rod.

[0011] Preferably, an arc-shaped guide plate is provided above the gear, and connecting posts are fixed between both sides of the guide plate and the two mounting plates.

[0012] Preferably, the barrier plate has an installation groove on the side facing the highest point of the screening frame, and a rubber plate can be detachably installed in the installation groove.

[0013] Compared with the prior art, the advantages of this utility model are as follows: by setting up an intermittent blocking part and an intermittent driving part, when the grinding ball rolls from the slope of the screening frame to the inside of the collection box, the intermittent driving part acts on two sets of blocking plates to move intermittently and alternately, thereby blocking the grinding ball on the inside of the screening frame, increasing the residence time of the grinding ball on the inside of the screening frame, so that the debris and burrs are more fully separated from the grinding ball, improving the screening effect of the grinding ball and enhancing its practicality.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-4 As shown, a deburring device for grinding balls includes a deburring box 1, a novel screening mechanism disposed directly below the discharge end of the deburring box 1, and a collection box 3 disposed beside the novel screening mechanism.

[0022] When in use, the grinding balls are first placed in the deburring box 1 for deburring treatment. Then, the deburred grinding balls fall into the new screening mechanism for screening treatment, so that the grinding balls are separated from the removed burrs. Finally, the grinding balls fall into the collection box 3 for collection for subsequent use.

[0023] A search of existing technology patent publication number CN214025163U reveals a surface deburring device for grinding smooth steel balls. From its content, it can be seen that the deburring box 1 is a burr treatment device that has been disclosed in the prior art and is well known to the public. This solution will not go into too much detail about its specific structure and operating principle. For details, please refer to the above document.

[0024] Specifically, refer to Figure 2-3 As shown, it is worth noting that the new screening mechanism includes an inclined screening frame 2, four sets of brackets 4 fixed to the bottom surface of the screening frame 2, a sieve plate 5 fixed to the bottom of the inner side of the screening frame 2, and a vibrator 6 installed on the side wall of the screening frame 2.

[0025] The highest end of the screening box 2 corresponds to the discharge end of the deburring box 1, and the collection box 3 is located below the lowest end of the screening box 2.

[0026] With the setting of vibrator 6, when the grinding balls enter the inner side of the screening frame 2 from the discharge end of the deburring box 1 and roll from the slope of the screening frame 2 to the inner side of the collection box 3, the vibrator 6 is continuously turned on to vibrate the entire screening frame 2 and screen plate 5. The vibration force is used to fully separate the debris and burrs from the grinding balls, improve the screening effect of the grinding balls, and enhance the practicality.

[0027] Furthermore, referring to Figure 2 and Figure 3As shown, it is worth noting that two lifting grooves are symmetrically opened on the sieve plate 5. Intermittent blocking parts are provided in the lifting grooves. The two sets of intermittent blocking parts are staggered and intermittent driving parts are provided between the two sets of intermittent blocking parts.

[0028] The intermittent blocking part is a blocking plate 7 that slides in the lifting groove;

[0029] By setting up intermittent blocking sections and intermittent driving sections, when the grinding balls roll from the inclined side of the screening frame 2 towards the inside of the collection box 3, the intermittent driving section causes the two sets of blocking plates 7 to move intermittently and alternately, thereby blocking the grinding balls on the inside of the screening frame 2, increasing the residence time of the grinding balls on the inside of the screening frame 2, so that the debris and burrs are more fully separated from the grinding balls, improving the screening effect of the grinding balls and enhancing practicality.

[0030] Furthermore, referring to Figure 3 As shown, it is worth noting that the intermittent drive unit includes a toothed plate 9 fixed to the bottom end of the baffle plate 7, and a transmission rod 10 is provided between the two toothed plates 9. The rod body of the transmission rod 10 is tightly sleeved with a gear 11 that meshes with the toothed plate 9.

[0031] The front and rear sides of the bottom end face of the screening frame 2 are vertically fixed with mounting plates 8. The transmission rod 10 rotates laterally between the two mounting plates 8. A forward and reverse motor 19 is installed on the outer wall of one of the mounting plates 8. The output shaft of the forward and reverse motor 19 rotates through the mounting plate 8 and is fixedly connected to one end of the transmission rod 10.

[0032] By setting the intermittent drive unit, the forward and reverse motor 19 is turned on. The output shaft of the forward and reverse motor 19 intermittently drives the transmission rod 10 to rotate in both directions. When the transmission rod 10 rotates in the forward direction, the gear 11 can mesh with the two toothed plates 9 in sync, so that the two toothed plates 9 and the two blocking plates 7 move up and down alternately. Conversely, when the transmission rod 10 rotates in the reverse direction, the two toothed plates 9 and the two blocking plates 7 move in opposite directions alternately.

[0033] Furthermore, referring to Figure 3 As shown, it is worth noting that a slider 12 is vertically fixed at the bottom of the side of the barrier plate 7, and a groove adapted to the slider 12 is vertically opened on the mounting plate 8.

[0034] With the setting of the slide groove and the slider 12, when the baffle plate 7 moves up and down, the slider 12 can slide synchronously inside the slide groove. In this way, the slide groove and the slider 12 can effectively limit the movement trajectory of the baffle plate 7 and ensure the stability of the baffle plate 7 when it moves.

[0035] Furthermore, referring to Figure 3 As shown, it is worth noting that an arc-shaped guide plate 13 is provided above the gear 11, and connecting posts 14 are fixed between the two sides of the guide plate 13 and the two mounting plates 8.

[0036] By setting the guide plate 13, a protective barrier can be effectively built above the gear 11 to prevent the burrs screened by the screen plate 5 from falling directly onto the gear 11 and affecting the meshing effect between the gear 11 and the toothed plate 9.

[0037] Furthermore, referring to Figure 3-4 As shown, it is worth noting that the barrier plate 7 is provided with an installation groove on the side facing the highest point of the screening frame 2, and a rubber plate 15 can be detachably installed in the installation groove.

[0038] By setting the rubber plate 15, the impact of the grinding ball on the barrier plate 7 can be reduced when the grinding ball rolls along the inclined plane of the screening frame 2, so as to prevent the grinding ball from hitting the barrier plate 7 hard, damaging the barrier plate 7, and affecting the service life of the barrier plate 7.

[0039] Furthermore, referring to Figure 4 As shown, it is worth noting that a fastening groove is vertically provided on the inner side wall of the mounting groove, and an mounting strip 16 is slidably inserted in the fastening groove. The top of the mounting strip 16 has a positioning post 17 that is fixedly connected to the inner wall of the bottom end of the fastening groove. The top of the positioning post 17 is threadedly connected to a locking cap 18 that abuts against the mounting strip 16.

[0040] After a period of use, when the flexible rubber sheet 15 hardens, simply turn the knob to tighten the locking cap 18, causing the locking cap 18 to disengage from the positioning post 17 under the threaded structure, thus contacting the fixing effect of the mounting strip 16 in the fastening groove. In this way, the rubber sheet 15 can be easily slid up to remove the mounting strip 16 from the fastening groove, which facilitates the disassembly of the rubber sheet 15.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
