Description

Technical Field

[0001] This utility model relates to the technical field of raw material screening devices, and in particular to a screening device for artificial quartz stone raw materials. Background Technology

[0002] Artificial quartz stone is composed of over 90% natural quartz and approximately 10% colorants, resins, and other additives for bonding and curing. It is a slab produced through a production process involving negative pressure vacuum molding, high-frequency vibration, and heat curing (the temperature varies depending on the type of curing agent).

[0003] When screening quartz raw materials, quartz particles of different sizes need to be screened and filtered through mesh bags with different apertures. The general screening method is to screen from top to bottom. This screening method has certain drawbacks. When the upper screen is blocked, it will affect the screening operation of the quartz material that is continuously conveyed. Therefore, a screening device for artificial quartz raw materials is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening device for artificial quartz stone raw materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A conveying screening mechanism is fixedly connected to the surface of the screening cylinder.

[0007] The conveying and screening mechanism includes a mounting plate fixedly connected to the surface of the screening cylinder. A motor is fixedly connected to the upper surface of the mounting plate. The output end of the motor passes through the inner wall of the stone cylinder and is fixedly connected to a feeding roller. A placement groove is opened on the surface of the feeding roller, and the surface of the feeding roller is in contact with the inner wall of the stone cylinder.

[0008] The inner wall of the screening cylinder is rotatably connected to a drive shaft, and a cam is fixedly connected to the surface of the drive shaft. The surface of the cam is in contact with the lower surface of the screening plate.

[0009] Preferably, a drive wheel is fixedly connected to the output end surface of the motor, a driven wheel is fixedly connected to the surface of the drive shaft, and a belt is fitted onto the surfaces of the drive wheel and the driven wheel.

[0010] Preferably, a telescopic rod is fixedly connected to the inner bottom wall of the screening cylinder, and a contact plate is fixedly connected to the top end of the telescopic rod.

[0011] Preferably, a spring is fitted onto the surface of the telescopic rod, and a cover plate is rotatably connected to the upper surface of the stone cylinder.

[0012] Preferably, the inner wall of the screening cylinder is fixedly connected with a first conical cylinder, a second conical cylinder and a third conical cylinder, and the upper surface of the screening cylinder is fixedly connected with a sleeve plate.

[0013] Preferably, the surface of the sleeve plate has a through hole, a flexible plate is inserted into the inner wall of the sleeve plate, and a pull plate is fixedly connected to one side of the flexible plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The inclined surface is inclined. The advantage of this is that, under the action of the up and down movement of the screening plate, the stone on the inclined surface is continuously transported to one side. The diameter of the first screening hole, the second screening hole and the third screening hole gradually increases from left to right, which is used to screen quartz particles of different sizes and then classify and recycle them through the corresponding first conical cylinder, second conical cylinder and third conical cylinder.

[0016] 2. During intermittent cyclic feeding, the cam drives the stones located on the inclined surface to be thrown into the air. The stones come into contact with the flexible plate for protection, preventing the stones from being crushed due to impact and affecting the final screening effect. The oscillating screening plate can continuously convey and screen the fed stones. Attached Figure Description

[0026] The conveying and screening mechanism includes a mounting plate 4 fixedly connected to the surface of the screening cylinder 1. A motor 5 is fixedly connected to the upper surface of the mounting plate 4. The output end of the motor 5 passes through the inner wall of the stone cylinder 2 and is fixedly connected to a feeding roller 8. A placement groove 9 is opened on the surface of the feeding roller 8, and the surface of the feeding roller 8 is in contact with the inner wall of the stone cylinder 2.

[0027] A drive shaft 12 is rotatably connected to the inner wall of the screening cylinder 1, and a cam 20 is fixedly connected to the surface of the drive shaft 12. The surface of the cam 20 is in contact with the lower surface of the screening plate 7.

[0028] In this utility model, a stone cylinder 2 is provided to store the stone to be screened. Multiple first screening holes 17, second screening holes 18, and third screening holes 19 are provided, with the hole diameters gradually increasing from left to right, to screen quartz particles of different sizes. A motor 5 is provided to drive the feeding roller 8 to rotate. A placement trough 9 is provided to discharge the stone located in the placement trough 9 during rotation. A cam 20 is provided to drive the screening plate 7 to move up and down under force to generate vibration, thereby performing the conveying and screening operation.

[0029] A drive wheel 10 is fixedly connected to the output end surface of the motor 5, and a driven wheel 13 is fixedly connected to the surface of the drive shaft 12. A belt 11 is fitted onto the surfaces of the drive wheel 10 and the driven wheel 13.

[0030] In this utility model, by setting a belt 11, the driving wheel 10 drives the driven wheel 13 to rotate via the belt 11.

[0031] A telescopic rod 21 is fixedly connected to the inner bottom wall of the screening cylinder 1, and a contact plate 23 is fixedly connected to the top of the telescopic rod 21.

[0032] In this invention, the contact plate 23 is supported by a telescopic rod 21. The contact plate 23 impacts the lower surface of the screening plate 7, causing the screening plate 7 to vibrate.

[0033] A spring 22 is fitted on the surface of the telescopic rod 21, and a cover plate 3 is rotatably connected to the upper surface of the stone cylinder 2.

[0034] In this invention, a spring 22 is provided to buffer the contact plate 23, and a cover plate 3 is provided to ensure the safety of the stone material in the stone cylinder 2 when it descends.

[0035] The inner wall of the screening cylinder 1 is fixedly connected with a first conical cylinder 14, a second conical cylinder 15 and a third conical cylinder 16, and the upper surface of the screening cylinder 1 is fixedly connected with a sleeve plate 6.

[0036] In this invention, by setting up a first conical cylinder 14, a second conical cylinder 15, and a third conical cylinder 16, stones of different diameters after screening are placed in the first conical cylinder 14, the second conical cylinder 15, and the third conical cylinder 16 respectively for recycling and sorting.

[0037] The surface of the sleeve plate 6 has a through hole 27, and a flexible plate 26 is inserted into the inner wall of the sleeve plate 6. A pull plate 25 is fixedly connected to one side of the flexible plate 26.

[0038] In this invention, by providing through holes 27, the stones on the screening plate 7 are cushioned and protected when they collide with the flexible plate 26 during movement. By providing pull plates 25, the operator can remove the flexible plate 26 located in the sleeve plate 6 by pulling the pull plates 25.

[0039] Working principle: During use, the motor 5 is started. The output of the motor 5 drives the feeding roller 8 and the drive wheel 10 to rotate. The rotating feeding roller 8 passes through the placement groove 9, conveying the stones in the stone cylinder 2 to the inclined surface 24 inside the screening cylinder 1. The rotation of the drive wheel 10 drives the driven wheel 13 to rotate through the belt 11. The rotation of the driven wheel 13 drives the cam 20 to rotate through the drive shaft 12. When the surface of the cam 20 contacts the lower surface of the screening plate 7, it causes one side of the screening plate 7 to be subjected to force, causing the screening plate 7 to rotate. Under the action of the cam 20, the screening plate 7 rotates and rises, throwing the stones on the screening plate 7 into the air, so that the stones can hit the surface of the flexible plate 26, ensuring that the stones can fall back into the screening cylinder. On plate 7, the screened stone is protected from impact to prevent it from breaking and affecting the screening effect. Under the action of the up and down movement of the screening plate 7, the stone on the inclined surface 24 is continuously conveyed to one side and screened through multiple first screening holes 17, second screening holes 18 and third screening holes 19. Finally, it is recovered through the first conical cylinder 14, second conical cylinder 15 and third conical cylinder 16. During the process of descending and resetting, the screening plate 7 impacts the upper surface of the contact plate 23, causing the screening plate 7 to vibrate. The contact plate 23 is buffered and protected by spring 22. With the above structure, the quartz stone is screened for different particle sizes to prevent clogging.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
