Description

Technical Field

[0001] This utility model belongs to the field of static presses, and in particular relates to a multifunctional double-pressure static press brick machine for producing multiple products. Background Technology

[0002] A static pressing brick machine is a mechanical device that uses static pressure to compress raw materials (such as fly ash, cement, sand, etc.) into brick blanks. It features high production efficiency, stable product quality, energy saving, and environmental friendliness, and is widely used in the building materials production field. Static presses are generally available in different pressure specifications ranging from 600 to 1200 tons, and can be divided into single-pressure static presses and double-pressure static presses. A double-pressure static press can press materials from two different directions or at different stages with different pressures. The template can move freely up and down, squeezing and pushing the molding sand in the pre-filled frame from the parting surface of the sand mold (sand box), achieving compaction of the molding sand from two directions. A single-pressure static press applies pressure to the material from a single direction. Taking a common downward-pressing static press as an example, the lower main hydraulic cylinder drives the lower movable crossbeam to apply hydraulic pressure to the powder through the lower die. The upper die forms a reaction force between the upper crossbeam and the middle frame, gradually compressing the powder until the brick blank is formed.

[0003] Currently, because some municipal bricks have colored surfaces and gray base bricks, brick making machines for these bricks are mostly bidirectional static pressing machines, such as the bidirectional static press and its production process disclosed in patent CN116674073A, which can produce colored facing bricks. In contrast, general unidirectional static presses are only used for the production of single-color bricks, such as the unidirectional pressure static press disclosed in existing patent CN218557507U. For general enterprises, the cost of matching multiple bidirectional and unidirectional static presses will increase significantly, which is not conducive to improving the overall utilization rate of equipment. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a multi-functional double-pressure static brick pressing machine for producing multiple products, including a main frame and a material placing machine. The main frame is provided with an upper mold, a middle frame, and a lower mold.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This utility model provides a multi-functional dual-pressure static pressing brick machine for producing multiple products.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figures 1-7As shown, this utility model provides a multi-functional double-pressure static brick pressing machine for producing multiple products, including a main frame 1 and a material feeding machine 9. The main frame 1 is provided with an upper mold 2, a middle frame 3 and a lower mold 4. The top of the upper mold 2 is provided with a main pressure cylinder 5, and the two sides of the middle frame 3 are provided with telescopic cylinders 6. The bottom of the main frame 1 is provided with a support platform 7 for installing the lower mold 4. The two sides of the support platform 7 are provided with mounting grooves 71, and the center of the support platform 7 is provided with a mounting frame 8. The two sides of the mounting frame 8 are provided with U-shaped openings 81 corresponding to the mounting grooves 71. The U-shaped openings 81 and the mounting grooves 71 are connected by T-bolts. A set of material feeding machines 9 is provided on both sides of the middle frame 3, namely a base layer material feeding machine 91 and a surface layer material feeding machine 92. Specifically, the main pressure cylinder 5 can drive the upper mold 2 to rise and fall and press the powder between the middle frame 3 and the lower mold 4 into shape; the telescopic cylinder 6 can drive the middle frame 3 to rise and fall and cause the pushing component or conveying component to push the brick blank to the conveyor, which is used to transfer the brick blank to the stacking station and the mechanical manual station; the material distribution machine 9 can reciprocate linearly between the upper mold 2 and the lower mold 4 through the cylinder or the conveying component, so that the powder falls from its interior between the lower mold 4 and the middle frame 3, thereby achieving the purpose of material distribution. Based on this, the present invention provides sufficient space by adopting a detachable support platform 7, mounting frame 8, and lower mold 4 to replace and install the lower cylinder component of the dual-pressure static press. The power end and control end of the switched lower cylinder component are connected to the oil station and control box respectively, which is conducive to switching between single-pressure static press and dual-pressure static press working modes and improving the overall utilization rate of the equipment. Furthermore, by adopting a base layer material placing machine 91 and a surface layer material placing machine 92, the equipment can realize the molding and manufacturing of multi-layer bricks, which meets the production requirements of municipal bricks. In particular, it is beneficial to save on the colored fabric of facing bricks, thereby improving the utilization rate of the equipment and reducing the raw material cost.

[0026] To improve the material feeding performance of the material feeding machine 9, the material feeding machine 9 provided by this utility model is internally equipped with multiple rotating material feeding components 93. A transmission mechanism 94 is provided at the end of each rotating material feeding component 93, and a geared motor 95 is provided at the power input end of the transmission mechanism 94. A hopper and a discharge valve are installed above the material feeding machine 9. The material feeding machine 9 receives powder from the hopper. A power component, such as a cylinder, hydraulic cylinder, or conveyor, is provided to drive the hopper. When the hopper moves horizontally above the middle frame 3, the rotating material feeding components 93 can continuously rotate to distribute the powder into different mold slots, resulting in better material feeding uniformity and helping to ensure the quality of the patent.

[0027] Furthermore, the rotating fabric component 93 provided by this utility model includes a material box, inside which are arranged three spaced star-shaped plates 931. End blocks 932 are provided at the ends of the star-shaped plates 931 located at both ends. An end shaft 933 is provided at the center of the end block 932. A bearing 934 and a bearing seat 935 are provided on the outer side of the end shaft 933. The star-shaped plate 931 includes a plurality of mounting teeth 9311. Mounting grooves 9312 are provided on the mounting teeth 9311. A material feeding plate 936 is provided in the mounting grooves 9312 located in the same axial direction on the three star-shaped plates 931. The bearing and bearing housing provide support for the end shaft 933. The end shaft 933 and the end block 932 can be connected by a key to achieve synchronous movement. The end shaft 933 can clamp the star plates 931 at both ends. The feeding plate 936 on the star plate 931 can rotate synchronously with the end shaft 933. During continuous rotation, the powder can be rolled into the corresponding material trough. Compared with the fixed feeding plate 936, the feeding effect of this rotating feeding component 93 is better.

[0028] Furthermore, the material feeding plate 936 provided by this utility model has a triangular cross-section with its apex facing the center of the star-shaped plate 931. In this way, the two inclined waist surfaces of the material feeding plate 936 can play the role of guiding the material, and an elongated material feeding orifice can be formed between adjacent material feeding plates 936. In addition, the material feeding plate 936 can rotate continuously around the rotation center of the end shaft 933, so it can avoid the situation of material piling up at one time, which would affect the translation performance of the material feeder 9, and ensure the actual material feeding effect of the material feeder 9.

[0029] To improve the assembly reliability of the material guide plate 936 and the star-shaped plate 931, the material guide plate 936 provided by this utility model is provided with a waist opening 9361 that engages with the mounting groove 9312, and a screw hole 9362 that radially corresponds to the mounting groove 9312. The screw hole 9362 is used to install screws. The waist opening 9361 is located on the edge of the material guide plate 936, and one waist opening 9361 can connect two edges, thereby achieving surface contact with the groove edge of the mounting groove 9312. This improves the stability of the material guide plate 936 in the rotational direction. Combined with the fixing effect of the screws, this effectively ensures the connection reliability between the material guide plate and the star-shaped plate 931.

[0030] To improve the transmission performance of the transmission mechanism 94, the transmission mechanism 94 provided by this utility model includes a driven gear 941 coaxially connected to the end shaft 933, and an intermediate gear 942 is provided between adjacent driven gears 941. An input gear 943 is provided at the transmission end of one of the intermediate gears 942. An input shaft 944 is provided at the center of the input gear 943. An output sprocket 945 is provided on the input shaft 944. An input sprocket 946 is provided at the transmission end of the output sprocket 945. The input sprocket 946 and the output sprocket 945 are connected by a chain. The input sprocket 946 is connected to the geared motor 95. The geared motor 95 transmits power to the input shaft 944 through the input sprocket 946, chain, and output sprocket 945. Two transmission paths can be arranged at both ends of the input shaft 944. The transmission path includes an input gear 943, a transition gear 942, and a driven gear 941, thereby transmitting power to all rotating fabric components 93. This ensures that all rotating fabric components 93 can receive power. Furthermore, this transmission path uses only gears and does not use additional chains and belts, which helps to ensure the safety of the fabric laying machine 9 during linear reciprocating movement.

[0031] 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 other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
