Abstract
Description
Technical Field
[0001] This utility model relates to mineral castings, specifically a feeding device for mineral castings. Background Technology
[0002] When producing mineral castings, various raw materials need to be poured into a feeding device, which then feeds the various raw materials in a certain proportion, thus achieving the mixing of the raw materials.
[0003] Mineral castings are products made by mixing raw materials such as granite fragments and epoxy resin and then pressing them. Currently, after mixing the raw materials, the mixed materials are delivered to a designated location using a conveyor belt or a spiral feeding shaft. However, the spiral feeding shaft at the bottom of the mixing tank causes some raw materials to fall directly into the gaps of the spiral shaft and fail to participate in the mixing, resulting in poor mixing effect. Utility Model Content
[0004] To address the shortcomings of the prior art, this invention provides a feeding device for mineral castings. The device has a feeding hole at the bottom of the mixing tank, which, together with an external feeding pipe and a blockage area, allows the feeding hole to be closed or opened without affecting the mixing effect, thus facilitating control.
[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a feeding device for mineral castings, comprising a mixing tank, wherein a feeding hole is provided at the bottom of the mixing tank, and a movable plate disposed on the bottom surface of the mixing tank, wherein the movable plate is provided with a feeding pipe, the feeding pipe being connected to the feeding hole for feeding, and the movable plate also being provided with a blocking area, the blocking area being able to block the feeding hole to stop feeding; the bottom of the mixing tank is also provided with an anti-fall bottom cover, and the side of the mixing tank is also provided with a driving component for driving the movable plate to move.
[0006] The bottom of the mixing tank is also provided with a guide groove, which covers the feeding hole. The moving plate is placed in the guide groove and moves along the guide groove.
[0007] The movable plate has a hole communicating with the feeding pipe for connecting the feeding pipe and the feeding hole. The thickness of the movable plate is greater than the thickness of the guide groove. The movable plate is also provided with a limiting piece, which is located outside the guide groove and close to the bottom surface of the mixing tank. The bottom surface of the mixing tank is also provided with a stop piece to stop the limiting piece.
[0008] The anti-fall bottom cover has side plates on three sides, and the side plates have welding plates for welding to the bottom surface of the mixing tank. The anti-fall bottom cover covers the movable plate, and the free end of the movable plate extends from the side without the side plate and is connected to the driving component. The anti-fall bottom cover has a movable groove, and the feeding pipe passes through the movable groove.
[0009] The driving component includes a cylinder and an auxiliary plate. The cylinder is fixed to the outer wall of the mixing tank, and one end of the auxiliary plate is connected to the cylinder and the other end is connected to the free end of the moving plate.
[0010] In summary, this utility model achieves the following technical effects:
[0011] This invention features a movable plate at the bottom of the mixing tank. The movable plate can open or close the feeding hole, allowing for feeding after mixing is complete or closed during mixing. This eliminates the need to remove the mixture from the mixing tank, thus automatically feeding the material. This replaces the method of setting a spiral shaft at the bottom of the mixing tank, solving the problem of poor mixing effect caused by raw materials falling into the gaps of the spiral shaft and not participating in the mixing in the prior art.

[0024] Example:
[0025] Figure 1 It is a feeding device used for mineral castings. Figure 2 yes Figure 1The side view includes a mixing tank 1, with a feeding hole 103 at the bottom of the mixing tank 1, and a movable plate 2 disposed on the bottom surface of the mixing tank 1. The movable plate 2 is provided with a feeding pipe 3, which communicates with the feeding hole 103 for feeding. The movable plate 2 is also provided with a blocking area, which can block the feeding hole 103 to stop feeding. The bottom of the mixing tank 1 is also provided with a fall-prevention cover 4, and the side of the mixing tank 1 is also provided with a driving component for driving the movable plate 2 to move.
[0026] This invention features a movable plate at the bottom of the mixing tank. The movable plate can open or close the feeding hole, allowing for feeding after mixing is complete or closed during mixing. This eliminates the need to remove the mixture from the mixing tank, thus automatically feeding the material. This replaces the method of setting a spiral shaft at the bottom of the mixing tank, solving the problem of poor mixing effect caused by raw materials falling into the gaps of the spiral shaft and not participating in the mixing in the prior art.
[0027] Figure 3 This is a schematic diagram of a mixing tank. The bottom of the mixing tank 1 is also provided with a guide groove 101, which covers the feeding hole 103. The moving plate 2 is placed in the guide groove 101 and moves along the guide groove 101.
[0028] In this invention, the movable plate slides within the guide groove. During the sliding process, when the feeding pipe aligns with the feeding hole, the mixture in the mixing tank is delivered to the designated position via the feeding pipe. When the feeding pipe completely leaves the feeding hole, i.e., when the blockage area blocks the feeding hole, the mixture cannot fall, and mixing can then commence. The guide groove serves to guide the movable plate, preventing it from slipping and ensuring alignment between the pipe and the hole, or between the blockage area and the hole.
[0029] The feed hole 103 is also equipped with a sealing ring 104 to prevent the mixture from leaking out.
[0030] Figure 4 This is a schematic diagram of a movable plate. The movable plate 2 has a hole that communicates with the feeding pipe 3, so as to connect the feeding pipe 3 with the feeding hole 103. The thickness of the movable plate 2 is greater than the thickness of the guide groove 101. The movable plate 2 is also provided with a limiting piece 201. The limiting piece 201 is located outside the guide groove 101 and is close to the bottom surface of the mixing tank 1. The bottom surface of the mixing tank 1 is also provided with a stop piece 102 to stop the limiting piece 201.
[0031] Figure 5 This is a schematic diagram of the movable plate and the mixing tank. The thickness of the movable plate 2 of this utility model is greater than the thickness of the guide groove 101, so that the bottom surface of the movable plate exceeds the guide groove, which makes it easier to set the limiting piece and also makes the movable plate stronger. Figure 4The dotted line indicates the blockage area. As the moving plate slides to the left, the blockage area gradually and completely covers the feed hole, thus achieving blockage and stopping the feeding. The limit plate and stop plate work together to prevent the blockage area from moving excessively, ensuring the blocking effect.
[0032] Figure 6 This is a schematic diagram of the anti-fall bottom cover. The anti-fall bottom cover 4 has side plates 401 on three sides. The side plates 401 are provided with welding plates 402 for welding to the bottom surface of the mixing tank 1. The anti-fall bottom cover 4 covers the movable plate 2. The free end of the movable plate 2 extends from the side without the side plates 401 and is connected to the driving component. The anti-fall bottom cover 4 has a movable groove 403, and the feeding pipe 3 passes through the movable groove 403.
[0033] This utility model welds an anti-fall bottom cover to the bottom of the mixing tank, covering the movable plate, leaving only one side for the movable plate to enter and exit. The inner wall of the anti-fall bottom cover is tightly fitted to the movable plate to prevent the feed pipe from detaching from the feed hole and causing the mixture to leak out. The movable groove 403 serves two purposes: firstly, to allow the feed pipe to move, and secondly, to limit its movement. Figure 1 The state shown is when the feeding pipe and the feeding hole are fully connected. At this time, the feeding pipe reaches the arc end of the movable groove and achieves the limit. When the moving plate moves to the left, the feeding pipe moves along the movable groove and can also provide a guiding function.
[0034] The driving component includes a cylinder 5 and an auxiliary plate 6. The cylinder 5 is fixed to the outer wall of the mixing tank 1, and one end of the auxiliary plate 6 is connected to the cylinder 5 and the other end is connected to the free end of the moving plate 2.
[0035] Working principle:
[0036] Various raw materials, such as natural granite fragments and epoxy resin, are added to the mixing tank. The mixing tank's built-in stirring shaft mixes the raw materials to form a mixture.
[0037] After mixing is completed, start cylinder 5 to drive moving plate 2 to the right. The blockage area gradually moves away from feeding hole 103. When there is a small connection between feeding pipe 3 and feeding hole 103, the mixture in the mixing tank will fall until feeding pipe 3 gradually aligns with feeding hole 103 and the mixture falls smoothly.
[0038] When feeding ends, cylinder 5 drives the moving plate to the left, moving the feeding pipe 3 away from the feeding hole 103. The blockage area gradually and completely covers the feeding hole 103, and feeding ends. Raw materials can be added to the mixing tank for mixing.
[0039] To facilitate material discharge, the feeding hole can be set near the center of the mixing tank. Since the bottom of a typical mixing tank is funnel-shaped with the center being the lowest point, the mixture can easily exit from this location without affecting the mixing process.
[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
