Description

Technical Field

[0001] This utility model relates to the field of abrasive processing technology, specifically to an abrasive mixing machine. Background Technology

[0002] Abrasives are widely used in manufacturing industries such as metal processing, plastic molding, and stone cutting. They are important tools for achieving high-precision and high-efficiency processing. With the development of the manufacturing industry, the application prospects of abrasives will be even broader. In the production of abrasives, mixers are used to mix raw materials. Existing abrasive mixers generally consist of a mixing chamber and a stirring core. During use, the drive unit drives the stirring core to stir the materials inside the mixing chamber. The mixing chamber is generally stationary, with a feeding port at the top and a discharge port at the bottom. As a result, the mixing chamber remains stationary during the mixing process, and there is a gap between the stirring core and the inner wall of the mixing chamber. Consequently, the material at the bottom tends to remain for a long time without being properly mixed. Furthermore, in order to facilitate the closure of the discharge port, its opening is generally small, resulting in low discharge efficiency and poor performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an abrasive mixer. The mixing tank itself can rotate to prevent materials from staying at the bottom, thereby improving the uniformity of the mixing of raw materials for abrasive processing. Furthermore, the feeding and discharging of the mixing tank can use a single feed port, which is controlled by a gear structure. This makes it easy to apply force, control, and discharge materials quickly, thereby improving the production efficiency and quality of abrasives. The machine has good performance and can effectively solve the problems in the background technology.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This embodiment provides a technical solution: an abrasive mixer, including a frame 1, a drive assembly 5, and an opening and closing assembly 7;

[0026] Frame 1: A mixing tank 2 is rotatably connected to its upper end. Frame 1 provides mounting positions for the components above. A stirring core 4 is rotatably connected to the middle of the mixing tank 2. The stirring core 4 consists of a central shaft and two spiral blades rotating in opposite directions, thereby stirring and mixing the materials inside. Inlet and outlet holes are opened on the outer arc surface of the mixing tank 2, through which raw materials for abrasive processing and other materials are added to the interior of the mixing tank 2. The inner arc wall of the mixing tank 2 is uneven due to the presence of the inlet and outlet holes, which can restrict the material from moving along the wall of the mixing tank 2. The mixing tank 2 slides, causing the material at the bottom to flip upwards, ensuring uniform mixing. A cover 3 is rotatably connected to the outside of the mixing tank 2, controlling the opening and closing of the inlet and outlet ports. Two positioning strips 9 are provided on the outer arc surface of the mixing tank 2, both of which cooperate with the cover 3. The left end of the cover 3 contacts the left-side positioning strip 9 to close the inlet and outlet ports of the mixing tank 2. The positioning strips 9 limit the rotation range of the cover 3. A PLC controller 6 is located at the front end of the frame 1, and the input terminals of the PLC controller 6 are electrically connected to the external... The mixing tank 2 has a power supply, and an iron plate 11 is located at the front end. Two proximity switches 8 are located on the front side of the frame 1, each engaging with the iron plate 11. Both proximity switches 8 are bidirectionally electrically connected to the PLC controller 6. When the lower proximity switch 8 is activated, and the mixing tank 2 moves the iron plate 11 to the position of the lower proximity switch 8, the proximity switch 8 sends an electrical signal to the PLC controller 6. The PLC controller 6 then stops the second motor 55. At this time, the inlet and outlet ports of the mixing tank 2 will remain at the lower position. The second motor 55 and the upper proximity switch... When switch 8 is activated, mixing tank 2 will drive iron plate 11 to rotate. When the inlet and outlet of mixing tank 2 rotates to the top, iron plate 11 corresponds to the position of proximity switch 8 above. Proximity switch 8 above sends an electrical signal to PLC controller 6, and motor 2 55 stops working, allowing material to be added. The lower end of the frame 1 is equipped with a chute 10, which is located below mixing tank 2. Material is discharged from the bottom of mixing tank 2 to the top of chute 10. The chute 10 is inclined downward from right to left, so that the material slides to the left and is collected on the left side.

[0027] Drive assembly 5: Used to drive the rotation of mixing tank 2 and stirring core 4. Drive assembly 5 includes support shell 51, motor 1 52, worm 53, worm wheel 54 and motor 2 55. Support shell 51 is located on the rear side of frame 1. Motor 1 52 is located on the rear side of support shell 51. The output shaft of motor 1 52 is fixedly connected to the rear end of stirring core 4. Motor 1 52 drives stirring core 4 to rotate. Worm wheel 54 is located at the rear end of mixing tank 2. Worm 53 is rotatably connected inside support shell 51. Worm 53 is meshed with worm wheel 54. Motor 2 55 is located on the rear side of frame 1. The output shaft of motor 2 55 is fixedly connected to the lower end of worm 53. The input ends of motor 1 52 and motor 2 55 are electrically connected to the output end of PLC controller 6. Motor 2 55 drives mixing tank 2 to rotate through worm 53 and worm wheel 54.

[0028] Opening and closing assembly 7 includes a gear ring 71, a support sleeve 72, and a gear 73. The gear ring 71 is located on the front side of the mixing tank 2. The support sleeve 72 is rotatably connected to the front end of the cover 3. The rear end of the outer arc surface of the support sleeve 72 is provided with a gear 73, which meshes with the gear ring 71. The gear 73 pushes the gear ring 71, causing the gear ring 71 to stop, thereby causing the support sleeve 72 to drive the cover 3 to rotate around the mixing tank 2. The opening and closing assembly 7 also includes a square bar 74, a post 75, a handwheel 76, a tension spring 77, and a socket 78. The square bar 74 is slidably connected to the inside of the support sleeve 72. The rear end of the square bar 74 is provided with a post 75. The front side of the mixing tank 2... Two insertion holes 78 are provided, both of which are configured to cooperate with the insertion post 75. A handwheel 76 is provided at the front end of the square bar 74. Rotating the handwheel 76 causes the support sleeve 72 and gear 73 to rotate via the square bar 74. A tension spring 77 is provided between the handwheel 76 and the front side of the support sleeve 72. The tension spring 77 is movably sleeved with the front end of the square bar 74. Pulling the handwheel 76 forward causes the square bar 74 to slide forward along the support sleeve 72 and stretch the tension spring 77. The square bar 74 causes the insertion post 75 to separate from the insertion hole 78 at the rear end. The insertion post 75 then movably inserts into the insertion hole 78 at the upper end, thereby locking and positioning the cover 3.

[0029] The working principle of the abrasive mixer provided by this utility model is as follows: During use, abrasive processing raw materials and other materials are added to the inside of the mixing tank 2 through the inlet and outlet ports. After addition, the handwheel 76 is pulled forward. The handwheel 76 drives the square bar 74 to slide forward along the support sleeve 72 and stretch the tension spring 77. The square bar 74 drives the insertion post 75 to separate from the insertion hole 78 at the rear end. Then, the handwheel 76 is rotated. The handwheel 76 drives the support sleeve 72 and gear 73 to rotate through the square bar 74. The gear 73 moves the gear ring 71, and the gear ring 71 stops. Then, the support sleeve 72 drives the sealing cover 3 to rotate around the mixing tank 2. The left end of the cover 3 contacts the positioning strip 9 on the left side to close the inlet and outlet ports of the mixing tank 2. Then, the handwheel 76 is released backward. The tension spring 77 drives the insert 75 backward through the handwheel 76 and the square strip 74. The insert 75 is then inserted into the upper insertion hole 78, thereby locking and positioning the cover 3. Then, the PLC controller 6 is activated, and motors 1 and 2 operate. Motor 1 drives the stirring core 4 to rotate. The stirring core 4 consists of a central shaft and two spiral blades rotating in opposite directions, thereby stirring and mixing the internal materials. At the same time, motor 2 drives the mixing core 4 through the worm gear 53 and worm wheel 54. Mixing tank 2 rotates. The inner arc wall of mixing tank 2 is uneven due to the presence of the inlet and outlet holes, which restricts the material from sliding along the entire circumference of the mixing tank 2 wall. Mixing tank 2 can cause the material at the bottom to flip upwards, ensuring uniform mixing. After mixing is complete, the PLC controller 6 is activated, and the proximity switch 8 below is activated. When mixing tank 2 moves the iron plate 11 to the position of the proximity switch 8 below, the proximity switch 8 sends an electrical signal to the PLC controller 6. The PLC controller 6 then controls motor 2 55 to stop running. At this time, the inlet and outlet holes of mixing tank 2 will remain at the bottom. Then, the handwheel 76 is operated to close the cover 3. When the mixing tank 2 is opened, the material is discharged from the bottom to the top of the chute 10. The chute 10 is tilted downwards from right to left, so the material slides to the left and is collected on the left side. After the material is discharged, the motor 1 52 is turned off when it is no longer in use. When processing is required, the PLC controller 6 is activated, the motor 2 55 and the proximity switch 8 above are activated, and the mixing tank 2 will drive the iron plate 11 to rotate. When the inlet and outlet of the mixing tank 2 rotates to the top, the position of the iron plate 11 corresponds to the position of the proximity switch 8 above. The proximity switch 8 above sends an electrical signal to the PLC controller 6, and the motor 2 55 stops working, so that material can be added.

[0030] It is worth noting that the PLC controller 6, proximity switch 8, motor 1 52 and motor 2 55 disclosed in the above embodiments can be freely configured according to the actual application scenario. The PLC controller 6 can be a PLC controller of model FX3U-16MR / ES-A, the proximity switch 8 can be a proximity switch of model LP-18P8C, and both motor 1 52 and motor 2 55 can be three-phase asynchronous motors of model Y112M-4. The PLC controller 6 controls the operation of proximity switch 8, motor 1 52 and motor 2 55 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
