Description

An inclined gasket screening machine Technical Field

[0001] This utility model relates to the field of screening machine technology, and in particular to an inclined pad screening machine. Background Technology

[0002] Gaskets are widely used in mechanical and engineering fields, playing important roles such as adjusting gaps or compensating for uneven surfaces, preventing loosening and stabilizing connections, bearing and distributing pressure, and conducting heat or providing electrical grounding. Gaskets are typically ring-shaped. After manufacturing, qualified gaskets usually have no burrs or only very fine burrs, while defective gaskets have larger burrs at the edges. Therefore, it is necessary to screen out these defective gaskets with larger burrs.

[0003] In the prior art, a screening machine is usually used to screen out defective gaskets with large burrs. This screening machine includes a frame, on which a screening disc and a drive mechanism are installed. The drive mechanism can drive the screening disc to rotate. The screening disc is set in a horizontal position. Multiple screening holes are arranged at the bottom of the screening disc. The diameter of the screening holes matches the diameter of the gasket. Qualified gaskets can fall out of the screening holes, while some defective gaskets with large burrs cannot fall out of the screening holes. However, this device that uses a screening disc to screen gaskets still has the following technical problems: (1) Some defective gaskets with large burrs can also fall out of the screening holes. Since the burrs of defective gaskets are often only present in a local position on the edge of the gasket, when the burrs of the gasket do not touch the screening holes, these defective gaskets with large burrs can still fall out of the screening holes, resulting in poor screening accuracy; (2) When the horizontally set screening disc rotates, the gasket is difficult to slide or roll in the screening disc, resulting in low screening efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an inclined pad screening machine that can improve screening accuracy and screening efficiency, in order to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an inclined gasket screening machine, comprising a frame, an inclined support platform, an inclined fixed plate, an inclined screening disc, a motor, and a transmission device. The inclined support platform is mounted on the frame, and its upper end has an inclined platform surface. The inclined fixed plate is mounted on the platform surface of the inclined support platform, and one end of the inclined fixed plate has a notch. The inclined screening disc is rotatably mounted on the inclined fixed plate, and there is sliding contact between the inclined screening disc and the inclined fixed plate. The inclined screening disc contains a mechanism for... The accommodating space for the gasket includes several screening zones at the bottom of the inclined screening disc that correspond to the notches on the fixed disc. Each screening zone has multiple screening holes, allowing the gasket to fall from the screening holes into the notches on the fixed disc. The inclined support platform is equipped with a screening disc shaft, the upper end of which movably passes through the inclined fixed disc and connects to the middle of the inclined screening disc. The motor is mounted on one side of the frame, and the transmission device is mounted on the frame. The lower end of the screening disc shaft is connected to the transmission device, and the power output end of the motor is connected to the transmission device to drive the screening disc shaft to rotate.

[0006] In the above technical solution, the tilt angle of the inclined support platform, the inclined fixed plate, the inclined screening plate and the screening plate rotating shaft is 1-40 degrees, preferably 5-30 degrees.

[0007] In the above technical solution, the inclined fixed plate is a circular fixed plate, and a funnel is installed on the lower side of the notch of the fixed plate. The center of the inclined fixed plate has a central hole through which the rotating shaft of the screening disc moves. The inclined screening disc is a circular screening disc, and the diameter of the inclined screening disc matches that of the inclined fixed plate. The inclined screening disc has 2-4 screening zones inside, and during the rotation of the inclined screening disc, each screening zone can rotate sequentially to the top of the notch of the fixed plate.

[0008] In the above technical solution, the screening disc shaft includes an upper shaft and a lower shaft that are connected to each other. A connecting flange is provided between the upper shaft and the lower shaft. An upper bearing is installed on the table surface of the inclined support platform. The upper shaft passes through the upper bearing and is installed in the upper bearing. A fixing plate is provided at the lower end of the inclined support platform. A lower bearing is installed on the fixing plate. The lower shaft passes through the lower bearing and is installed in the lower bearing.

[0009] In the above technical solution, the transmission device includes a first gear, a worm, a second gear, a transmission shaft, a third gear, a first pulley, a second pulley, and a belt. The first gear is installed at the lower end of the screening disc shaft. The worm has helical teeth that mesh with the first gear. The second gear is installed on one end of the worm. The third gear is installed on one end of the transmission shaft and meshes with the second gear. The first pulley is installed on the other end of the transmission shaft. The second pulley is installed on the motor shaft. The belt is wound around the first pulley and the second pulley. The diameter of the second gear is larger than the diameter of the third gear, and the diameter of the first pulley is larger than the diameter of the second pulley.

[0010] In the above technical solution, one end of the worm is provided with a sleeve, and the second gear is fixedly connected to the sleeve; a manual moving mechanism is also installed on the frame, which is used to push the sleeve to move along the length direction of the worm, so that the second gear on the sleeve can mesh with or separate from the third gear.

[0011] In the above technical solution, the manual moving mechanism includes a manual rotating handle, a rocker arm, a fourth gear, a guide rod, and a "T"-shaped pusher. The rotating handle is installed at one end of the rocker arm, and the fourth gear is installed at the other end of the rocker arm. The upper end of the "T"-shaped pusher has a guide hole.

[0012] The beneficial effects of this utility model are: (1) This utility model has an inclined fixed plate, one end of which has a plate notch. The inclined screening plate is rotatably mounted on the inclined fixed plate. The inclined screening plate and the inclined fixed plate are in sliding contact. The bottom of the inclined screening plate has several screening areas corresponding to the plate notch. Each screening area has multiple screening holes. The pad can fall from the screening hole into the plate notch. Therefore, when the qualified pad falls into the screening hole of the screening area, the qualified pad can fall completely into and be temporarily stored in the screening hole. When the screening hole of the screening area rotates to the position of the plate notch, the qualified pad will fall from the screening hole into the plate notch. On the one hand, when a defective pad with large burrs falls into the screening hole of the screening area, the defective pad will be blocked by the inclined plate and cannot fall completely into the screening hole. The burrs will be stuck by the hole wall of the screening hole. When the screening hole of the screening area rotates to the position of the plate notch, the defective pad will have difficulty falling from the screening hole into the plate notch, thus greatly improving the screening accuracy; (2) The inclined support table, the inclined plate, the inclined screening plate and the screening plate shaft of this utility model are all in an inclined state. When the screening plate rotates, it can help the pad slide or roll in the screening plate. The qualified pad can fall into the screening hole more easily, thus greatly improving the screening efficiency. Attached Figure Description

[0018] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] As shown in Figures 1-5, this utility model is an inclined gasket screening machine, including a frame 1, an inclined support platform 2, an inclined fixed plate 3, an inclined screening disc 4, a motor 5, and a transmission device. The inclined support platform 2 is mounted on the frame 1, and its upper end has an inclined platform surface 21. The inclined fixed plate 3 is mounted on the platform surface 21 of the inclined support platform 2, and one end of the inclined fixed plate 3 has a plate notch 31. The inclined screening disc 4 is rotatably mounted on the inclined fixed plate 3, and the inclined screening disc 4 and the inclined fixed plate 3 are in sliding contact. The inclined screening disc 4 has a receiving space for accommodating gaskets, and the bottom of the inclined screening disc 4 has several notches corresponding to the plate notch 31. The corresponding screening area 41 has multiple screening holes 42 arranged in each screening area 41. The size of the screening holes 42 is slightly larger than the size of the pad. For example, when the pad is an annular pad, the diameter of the screening hole 42 is 0.1mm-0.3mm larger than the diameter of the pad, and the pad can fall into the fixed plate notch 31 from the screening hole 42. The inclined support platform 2 is equipped with a screening plate rotating shaft 7. The upper end of the screening plate rotating shaft 7 moves through the inclined fixed plate 3 and connects to the middle of the inclined screening plate 4. The motor 5 is installed on one side of the frame 1, and the transmission device is installed on the frame 1. The lower end of the screening plate rotating shaft 7 is connected to the transmission device. The power output end of the motor 5 is connected to the transmission device so as to drive the screening plate rotating shaft 7 to rotate through the transmission device.

[0020] In this invention, when screening pads, the pads are poured into the receiving space of the inclined screening disc 4. The motor is started, and the motor drives the inclined screening disc 4 to rotate through the transmission device. Qualified pads fall from the screening hole 42 into the fixed plate notch 31 for output, while defective pads with burrs remain in the inclined screening disc 4. When a qualified pad falls into the screening hole 42 of the screening area 41, the qualified pad can fall completely into and be temporarily stored in the screening hole 42. When the screening hole 42 of the screening area 41 rotates to the position of the fixed plate notch 31, the qualified pad will fall from the screening hole 42 into the fixed plate notch 31. When a defective pad with large burrs falls into the screening hole 42 of the screening area 41, the defective pad will be blocked by the inclined fixed plate 3 and cannot fall completely into and be temporarily stored in the screening hole 42. The burrs will be blocked by the holes of the screening hole 42. When the screen is blocked by the wall, and the screening hole 42 of the screening area 41 rotates to the position of the fixed plate notch 31, the defective pad is difficult to fall from the screening hole 42 into the fixed plate notch 31, thereby greatly improving the screening accuracy. The inclined support platform 2 of this utility model has an inclined table 21, an inclined fixed plate 3, an inclined screening plate 4 and a screening plate rotating shaft 7, all of which are in an inclined state. When the screening plate rotates, it is conducive to the pad sliding or rolling in the screening plate, and the qualified pad can fall into the screening hole 42 more easily, thereby greatly improving the screening efficiency.

[0021] As shown in Figures 1 and 3-5, the tilt angle of the inclined support platform 2, the inclined plate 3, the inclined screening plate 4, and the screening plate shaft 7 is 1-40 degrees, preferably 5-30 degrees.

[0022] As shown in Figures 1 and 3-5, the inclined fixed plate 3 is a circular fixed plate. A funnel 32 is installed on the lower side of the notch 31 of the fixed plate. The center of the inclined fixed plate 3 has a fixed plate central hole 33 through which the screening disc rotating shaft 7 moves. The inclined screening disc 4 is a circular screening disc, and the diameter of the inclined screening disc 4 matches that of the inclined fixed plate 3. The inclined screening disc 4 has 2-4 screening zones 41. During the rotation of the inclined screening disc 4, each screening zone 41 can rotate sequentially to the top of the notch 31 of the fixed plate.

[0023] As shown in Figures 1 and 3-5, the screening disc shaft 7 includes an upper shaft portion 71 and a lower shaft portion 72 connected to each other. A connecting flange 73 is provided between the upper shaft portion 71 and the lower shaft portion 72. An upper bearing 74 is installed on the platform 21 of the inclined support platform 2. The upper shaft portion 71 passes through the upper bearing 74 and is installed within the upper bearing 74. A fixing plate 75 is provided at the lower end of the inclined support platform 2. A lower bearing 76 is installed on the fixing plate 75. The lower shaft portion 72 passes through the lower bearing 76 and is installed within the lower bearing 76. This structure allows the screening disc shaft 7 to be easily disassembled and installed, and ensures stable and reliable rotation.

[0024] As shown in Figures 1 and 3-5, the transmission device includes a first gear 8, a worm 9, a second gear 10, a drive shaft 11, a third gear 12, a first pulley 13, a second pulley 14, and a belt 15. The first gear 8 is mounted on the lower end of the screening disc shaft 7. The worm 9 has helical teeth 91 that mesh with the first gear 8. The second gear 10 is mounted on one end of the worm 9. The third gear 12 is mounted on one end of the drive shaft 11 and meshes with the second gear 10. The first pulley 13 is mounted on the other end of the drive shaft 11. The second pulley 14 is mounted on the shaft of the motor 5. The belt 15 is wound around the first pulley 13 and the second pulley 14. The diameter of the second gear 10 is larger than the diameter of the third gear 12, and the diameter of the first pulley 13 is larger than the diameter of the second pulley 14. This structure allows the transmission device to transmit motor power while also reducing speed.

[0025] As shown in Figures 1 and 3-5, one end of the worm gear 9 is provided with a sleeve 16, and the second gear 10 is fixedly connected to the sleeve 16. A manual moving mechanism is also installed on the frame 1. The manual moving mechanism is used to push the sleeve 16 to move along the length direction of the worm gear 9, so that the second gear 10 on the sleeve 16 can mesh with or disengage from the third gear 12. When the inclined fixed plate 3 and the inclined screening plate 4 are stuck by the gasket, the second gear 10 and the third gear 12 can be separated by the manual moving mechanism for maintenance, eliminating the problem of the gasket being stuck. Preferably, the manual moving mechanism includes a manual rotating handle 17, a rocker arm 18, a fourth gear 19, a guide rod 20, and a "T"-shaped pusher 24. The rotating handle is installed at one end of the rocker arm 18, and the fourth gear 19 is installed at the other end of the rocker arm 18. The upper end of the "T"-shaped pusher 24 is provided with a guide hole. The guide rod 20 is located above the worm gear 9 and parallel to the worm gear 9. The guide rod 20 moves through the guide hole, allowing the upper end of the "T"-shaped pusher 24 to move back and forth along the guide hole. The upper end of the "T"-shaped pusher 24 is provided with a spur rack, and the fourth gear 19 meshes with the spur rack. The lower end of the "T"-shaped pusher 24 is connected to the sleeve 16.

[0026] As shown in Figures 1 and 3-5, a rotating disk 25 is installed at one end of the drive shaft 11, and a handle 26 is installed on one side of the rotating disk 25. When the inclined fixed disk 3 and the inclined screening disk 4 are stuck by the gasket, the rotating disk 25 can be rotated in the opposite direction by the handle 26, thereby rotating the inclined screening disk 4 in the opposite direction to eliminate the problem of the gasket being stuck.

[0027] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
