Abstract
Description
Technical Field
[0001] This utility model relates to the field of artificial quartz stone slab production technology, and in particular to a mixing and stirring device for the production of artificial quartz stone slabs. Background Technology
[0002] In the production of artificial quartz stone slabs, mixing is a crucial process affecting the final slab quality. Existing mixing devices add raw materials directly into the mixing tank, easily introducing larger particles or foreign matter, leading to uneven mixing and affecting the slab's strength and appearance. Furthermore, raw materials are often added from one side of the top of the device, causing them to accumulate in the corners of the mixing tank. This results in uneven stress on the rotating blades, accelerating wear and shortening the equipment's lifespan over time. These problems not only reduce production efficiency but also increase maintenance costs. Therefore, an improved device is needed to prevent impurities from entering and raw material accumulation, improving mixing efficiency and equipment durability. Utility Model Content
[0003] The purpose of this invention is to solve the problem that existing technologies have the disadvantage of easy accumulation in the side walls and corners of the mixing tank, resulting in uneven force on the mixing blades during the mixing process. Therefore, this invention proposes a mixing device for the production of artificial quartz stone slabs.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A mixing device for producing artificial quartz stone slabs includes a mixing tank and a partition cylinder fixed to the top of the mixing tank. A cover plate is fixed to the top of the partition cylinder, and a baffle plate is hinged to one side of the cover plate.
[0006] A stirring rod and multiple stirring blades fixed to the outer wall of the stirring rod;
[0007] A frustum-shaped guide ring is fixed to the inner wall of the partition cylinder, and its inner wall is inclined to guide the raw material to slide towards the center.
[0008] A sieve plate is located below a frustum-shaped guide ring, and multiple sieve holes are opened on the surface of the sieve plate;
[0009] When the baffle is open, the raw material is guided to the sieve plate through the inner wall of the frustum-shaped guide ring, and screened through the sieve holes to prevent foreign objects from entering the mixing tank. Qualified raw materials fall into the center of the mixing tank. When the baffle is closed, the stirring rod drives the stirring blade to rotate and stir.
[0010] In one possible design, connecting frames are fixed on both sides of the sieve plate;
[0011] Guide rods are fixed on both sides of the bottom wall of the frustum-shaped guide ring, and the connecting frame is slidably sleeved on the outer wall of the guide rods.
[0012] In one possible design, an arc-shaped plate is fixed to the bottom of the sieve plate, with the two ends of the inner wall of the arc-shaped plate gradually moving away from the center of the stirring rod;
[0013] A backing plate is fixed to the outer wall of the stirring rod;
[0014] The guide rod is fitted with a spring on its outer wall, and the two ends of the spring are connected to the guide rod and the connecting frame respectively through spring seats;
[0015] When the stirring rod rotates, the abutment plate contacts the inner wall of the arc-shaped plate, pushing the screen plate to move. The spring drives the reset to achieve the reciprocating motion of the screen plate.
[0016] In one possible design, the sieve plate has an elongated through hole at its center, the direction of which is parallel to the direction of movement of the sieve plate.
[0017] The stirring rod passes through a frustum-shaped guide ring and an elongated through hole.
[0018] In one possible design, a connecting strip is fixed to the top of the sieve plate, with one end of the connecting strip extending below the baffle.
[0019] A push plate is fixed to the bottom of the baffle, and the push plate and the connecting strip are engaged by an arc surface.
[0020] When the baffle is closed, the pusher plate pushes the connecting strip to move the sieve plate, causing the sieve plate to move out of the rotation range of the stirring rod.
[0021] In one possible design, a cover is fixedly fitted on the outer wall of the stirring rod, the cover being located above the sieve plate and covering the elongated through hole.
[0022] In one possible design, a motor is mounted on the top of the cover plate, and one end of the stirring rod is fixedly connected to the motor output shaft.
[0023] In this application, during actual use, the drive motor can drive the connected stirring rod to rotate, which in turn drives the outer wall abutment plate to rotate. When the abutment plate rotates, it will touch the inner wall of the arc-shaped plate, thereby pushing the arc-shaped plate and causing the sieve plate to move laterally. Then, the sieve plate is reset by a spring, thus realizing the reciprocating motion of the sieve plate. By rotating and opening the baffle, raw materials can be added. The added raw materials will slide along the inner wall of the frustum-shaped guide ring towards the center, and then be screened through the sieve holes on the surface of the sieve plate, thereby preventing large particles or other foreign objects from entering the mixing tank. Qualified raw materials will enter the inner center of the mixing tank, preventing them from accumulating in the side corners of the mixing tank. When the baffle is rotated and closed, the push plate on one side of the baffle will abut against the connecting strip, thereby pushing the connecting strip to move. The connecting strip will drive the sieve plate to move, causing the arc-shaped plate at the bottom of the sieve plate to move out of the rotation range of the abutment plate. At this time, the drive motor can drive the stirring rod and the stirring blades on the outer wall to rotate independently for mixing, thereby avoiding the sieve plate.
[0024] In this utility model, the mixing and stirring device for producing artificial quartz stone slabs can screen the raw materials when adding them through a sieve plate, which can prevent larger particles or other foreign objects from entering the mixing tank, thereby ensuring the uniformity of mixing and the quality of the subsequent slabs, and improving the product qualification rate.
[0025] In this utility model, the mixing and stirring device for the production of artificial quartz stone slabs can achieve the effect of the raw materials automatically sliding along the inner wall towards the center when they are added through the frustum-shaped guide ring, thereby avoiding the raw materials from accumulating in the side corners of the mixing tank, reducing the wear of the stirring blades due to uneven force during the mixing process, and extending their service life.
[0026] In this invention, during use, it can help screen raw materials to prevent foreign objects from entering, and at the same time guide the raw materials to reduce the accumulation of raw materials on the side wall of the tank, thereby reducing the uneven force on the stirring blades, thus improving production quality and increasing the service life of the device.

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0033] In one embodiment: Reference Figure 1-2 A mixing and stirring device includes: a mixing tank 1, a partition cylinder 2, a stirring rod 9, a frustum-shaped guide ring 3, a sieve plate 13, and other components.
[0034] The partition cylinder 2 is installed on the top of the mixing tank 1, and a cover plate 5 is fixedly installed on its top. A baffle 4 is hinged to one side of the cover plate 5.
[0035] A stirring rod 9 is installed inside the mixing tank 1, and multiple stirring blades 8 are fixedly installed on its outer wall. One end of the stirring rod 9 is fixedly connected to the output shaft of the motor 7 installed on the top of the cover plate 5. When the motor 7 is driven, the output shaft of the motor 7 drives the stirring rod 9 to rotate, which in turn drives the stirring blades 8 to rotate, thereby realizing the stirring and mixing of the raw materials in the mixing tank 1.
[0036] A frustum-shaped guide ring 3 is fixedly installed on the inner wall of the partition cylinder 2. When raw materials are added, the raw materials slide along the inner wall of the frustum-shaped guide ring 3 towards the center, which guides and concentrates the raw materials, preventing them from scattering directly on the edge of the mixing tank 1.
[0037] The sieve plate 13 is used to screen raw materials and is located at the bottom of the frustum-shaped guide ring 3. Multiple sieve holes 14 are formed on the surface of the sieve plate 13. Qualified raw materials can pass through the sieve holes 14 and enter the center of the mixing tank 1, while larger particles or other foreign objects are intercepted on the sieve plate 13. An elongated through-hole 15 is formed at the center of the surface of the sieve plate 13. The stirring rod 9 passes through the frustum-shaped guide ring 3 and the elongated through-hole 15. The direction of the elongated through-hole 15 is the same as the direction of movement of the sieve plate 13 to ensure that the stirring rod 9 can smoothly pass through the sieve plate 13 without affecting its movement.
[0038] Connecting frames 12 are fixedly installed on both sides of the outer wall of the sieve plate 13, and guide rods 10 are fixedly installed on both sides of the bottom wall of the frustum-shaped guide ring 3. The connecting frames 12 are slidably sleeved on the outer wall of the guide rods 10 on the same side, and the guide rods 10 guide the movement of the sieve plate 13. An arc-shaped plate 17 is fixedly installed at the bottom of the sieve plate 13, with one end of the inner wall of the arc-shaped plate 17 close to the center of the stirring rod 9 and the other end gradually moving away. A stop plate 16 is fixedly installed on the outer wall of the stirring rod 9, and a spring 11 is sleeved on the outer wall of the guide rod 10. The two ends of the spring 11 are connected to the outer wall of the guide rod 10 and one side of the connecting frame 12 respectively through spring seats. When the stirring rod 9 rotates, the stop plate 16 on the outer wall of the stirring rod 9 rotates. When the stop plate 16 rotates, it will touch the inner wall of the arc-shaped plate 17, thereby pushing the arc-shaped plate 17 and thus causing the sieve plate 13 to move laterally. Then, the sieve plate 13 is reset under the elastic force of the spring 11, thereby realizing the reciprocating motion of the sieve plate 13 and improving the screening effect.
[0039] Specifically, the drive motor 7 drives the connected stirring rod 9 to rotate, thereby driving the outer wall abutment plate 16 to rotate, thus realizing the reciprocating motion of the sieve plate 13;
[0040] After the staff rotates and opens the baffle 4, the raw materials can be added. The added raw materials will slide along the inner wall of the frustum-shaped guide ring 3 towards the center, and then be screened through the sieve holes 14 on the surface of the sieve plate 13. This prevents larger particles or other foreign objects from entering the mixing tank 1. Qualified raw materials will then enter the inner center of the mixing tank 1, preventing them from all accumulating in the side corners of the mixing tank 1.
[0041] This application can be used in the field of artificial quartz stone slab production, or in other fields applicable to this application.
[0042] In another embodiment: Reference Figure 3 A mixing and stirring device for the production of artificial quartz stone slabs is disclosed. The device is applied in the field of artificial quartz stone slab production. A connecting strip 19 is fixedly installed on the top of a sieve plate 13, with one end extending to the bottom of a baffle plate 4. A push plate 18 is fixedly installed at the bottom of the baffle plate 4. Both the top of one side of the connecting strip 19 and the bottom of one side of the push plate 18 have curved surfaces for mutual engagement. A clearance hole 20 is provided on the surface of the connecting strip 19, through which a stirring rod 9 passes. When the baffle plate 4 is rotated closed, the push plate 18 on one side of the baffle plate 4 will abut against the connecting strip 19, thereby pushing the connecting strip 19 to move. The connecting strip 19 will then drive the sieve plate 13 to move, causing the curved plate 17 at the bottom of the sieve plate 13 to disengage from the rotation range of the abutment plate 16. At this time, the drive motor 7 can independently drive the stirring rod 9 and the stirring blades 8 on the outer wall to rotate for mixing and stirring, thus avoiding the sieve plate 13.
[0043] Furthermore, the baffle 4 is closed and fixed to the partition cylinder 2 by existing latches to ensure stability during stirring and mixing.
[0044] refer to Figure 4 The outer wall of the stirring rod 9 is fixedly fitted with a cover 21. The cover 21 is located above the sieve plate 13 and is used to cover the elongated through hole 15 to prevent the raw material from directly entering the mixing tank 1 through the elongated through hole 15.
[0045] refer to Figure 1 After the raw materials are added or the mixing is completed, the staff can clean the waste remaining on the surface of the screen plate 13. A support bracket 6 is fixedly installed at the bottom of the outer wall of the mixing tank 1 for support.
[0046] However, as is well known to those skilled in the art, the working principle and wiring method of motor 7 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0047] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
[0048] 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.
