Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a continuous extrusion molding device for clay. Background Technology

[0002] A clay extruder is a device that uses mechanical external force (such as a screw conveyor, hydraulic cylinder or piston) to transport plastic clay (such as ceramic clay, clay, brick and tile clay, etc.) from the hopper to the mold, and then extrudes it into a specific shape (such as rod, tube, flat plate, honeycomb, etc.) after being formed by the mold.

[0003] In existing technology, the connection between the die and the barrel of a clay extruder is generally achieved using a flange connection. Clay has high viscosity, and even slight misalignment or gaps at the flange connection can lead to clay residue and accumulation. This can cause clay to stagnate and become discontinuous during extrusion as it passes through the die-barrel connection, affecting extrusion quality. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a continuous extrusion molding device for clay materials to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of the present invention provides a continuous extrusion molding device for clay, comprising a machine body and a die. The machine body is provided with a hopper, and the front end of the machine body is provided with an extrusion cylinder. The front end of the extrusion cylinder is provided with a conical portion. The end of the conical portion and the rear end of the die are respectively fixedly connected to a first connecting plate and a second connecting plate. The front end of the first connecting plate is fixedly connected to a connector with a conical structure. The rear end of the inner side of the die is provided with a conical opening, and the front end of the inner side of the die is provided with a forming opening. The first connecting plate and the second connecting plate are provided with connecting members that can stably connect the two.

[0007] The above technical solution involves the following process: During extrusion, the clay flows from the extrusion cylinder to the conical section, and then flows through the conical section into the connector and conical orifice. During this process, the flow channel becomes increasingly narrow, and the clay is continuously compressed and contracted, eventually entering the forming orifice through the conical orifice for extrusion. The extrusion cylinder smoothly delivers the clay to the die orifice via the connector and conical orifice, without any jamming caused by the connection of the first and second connecting plates. This results in smoother and more continuous clay extrusion, which is beneficial for improving extrusion quality.

[0008] Preferably, in any of the above solutions, a pad is provided between the first connecting plate and the second connecting plate.

[0009] The above technical solution is adopted: the first connecting plate and the second connecting plate provide conditions for the connection between the extrusion cylinder and the die orifice. A pad is set between the two. After the two are connected, the pad is squeezed and deformed to seal the gap between the two and ensure the sealing of the connection.

[0010] Preferably, in any of the above embodiments, the inclination angle of the tapered opening is the same as the inclination angle of the connector, and the length of the tapered opening is greater than the length of the connector.

[0011] The above technical solution involves controlling the tilt angle and length of the conical opening to make the mud flow more smoothly from the connector into the conical opening.

[0012] Preferably, in any of the above schemes, the first connecting plate and the second connecting plate are flange plates, and the connecting parts are bolts and nuts arranged evenly on the flange plates in a circular pattern.

[0013] The above technical solution utilizes flanges, bolts, and nuts to connect the extrusion cylinder and the die, offering advantages such as reliable structure, strong sealing, and resistance to vibration and displacement.

[0014] Preferably, in any of the above solutions, a washer is provided between the bolts and nuts of the connecting member and the first connecting plate and the second connecting plate.

[0015] By adopting the above technical solution, adding a shim when tightening the bolts and nuts can effectively enhance the sealing performance, distribute pressure, prevent loosening, protect the connection surface, and compensate for installation errors.

[0016] Preferably, the connector is a quick-release clamp, as described in any of the above solutions.

[0017] The above technical solution utilizes quick-connect clamps, a type of fastening fixture for rapid pipe connections. These clamps, consisting of chucks, clamps, and gaskets, enable quick installation and removal while ensuring a secure and airtight connection. No welding or complex tools are required; the connection can be completed manually, significantly saving time and labor costs.

[0018] Preferably, in any of the above solutions, a sealing gasket is provided on the inner side of the connector, and the edges of the outer sides of the first connecting plate and the second connecting plate are rounded.

[0019] The above technical solution employs a sealing gasket that forms a seal between the connector and the first and second connecting plates, improving the sealing effect. The edges of the first and second connecting plates are rounded to facilitate the installation of the connector onto them.

[0020] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0021] 1. This continuous extrusion molding device for clay, through the arrangement of a conical section, a first connecting plate, a second connecting plate, a connector, a conical orifice, a molding orifice, and connecting parts, allows the clay to flow from the extrusion cylinder to the conical section during extrusion. From there, it flows through the conical section into the connector and the conical orifice. During this process, the flow channel narrows, and the clay is continuously compressed and contracted, eventually entering the molding orifice through the conical orifice for extrusion. The extrusion cylinder smoothly delivers the clay to the die through the connector and the conical orifice, without any jamming caused by the connection of the first and second connecting plates. This results in smoother and more continuous clay extrusion, which is beneficial for improving extrusion quality.

[0022] 2. In this continuous extrusion molding device for clay, the first and second connecting plates provide conditions for the connection between the extrusion cylinder and the die. A pad is placed between the two plates. After the connection, the pad is deformed by compression, sealing the gap between the two plates and ensuring the airtightness of the connection. By controlling the inclination angle and length of the conical orifice, the clay flows more smoothly from the connector into the conical orifice.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1-3 As shown, this utility model includes a machine body 1 and a die 7. A hopper 2 is provided on the machine body 1. An extrusion cylinder 3 is provided at the front end of the machine body 1. A conical part 4 is provided at the front end of the extrusion cylinder 3. A first connecting plate 5 and a second connecting plate 8 are fixedly connected to the end of the conical part 4 and the rear end of the die 7, respectively. A connector 6 with a conical structure is fixedly connected to the front end of the first connecting plate 5. A conical opening 9 is provided at the rear end of the inner side of the die 7. A forming opening 10 is provided at the front end of the inner side of the die 7. Connecting members 11 that can stably connect the first connecting plate 5 and the second connecting plate 8 are provided.

[0032] Specifically, during the extrusion process, the clay flows from the extrusion cylinder 3 to the conical section 4, and then flows through the conical section 4 into the connector 6 and the conical opening 9. During this process, the flow channel becomes smaller and smaller, and the clay is continuously squeezed and contracted, eventually entering the forming opening 10 from the conical opening 9 for extrusion. The extrusion cylinder 3 smoothly conveys the clay to the die opening 7 through the connector 6 and the conical opening 9, without any jamming due to the connection of the first connecting plate 5 and the second connecting plate 8. The clay extrusion is smoother and more continuous, which is beneficial to improving the extrusion quality.

[0033] Example 1: A pad 12 is provided between the first connecting plate 5 and the second connecting plate 8. The inclination angle of the conical opening 9 is the same as the inclination angle of the plug 6, and the length of the conical opening 9 is greater than the length of the plug 6.

[0034] Specifically: the first connecting plate 5 and the second connecting plate 8 provide conditions for the connection between the extrusion cylinder 3 and the die 7. A pad 12 is set between the two. After the two are connected, the pad 12 is deformed by compression, sealing the gap between the two and ensuring the sealing of the connection. By controlling the inclination angle and length of the conical orifice 9, the mud flows more smoothly from the insertion joint 6 into the conical orifice 9.

[0035] Example 2: The first connecting plate 5 and the second connecting plate 8 are flange plates, and the connecting parts 11 are bolts and nuts evenly arranged on the flange plates in several groups. Gaskets are provided between the bolts and nuts of the connecting parts 11 and the first connecting plate 5 and the second connecting plate 8.

[0036] Specifically, the extrusion cylinder 3 and the die 7 are connected together using a flange with bolts and nuts, which has advantages such as reliable structure, strong sealing performance, and resistance to vibration and displacement. Adding a gasket when tightening the bolts and nuts can effectively enhance the sealing performance, distribute pressure, prevent loosening, protect the connection surface, and compensate for installation errors.

[0037] Example 3: Connector 11 uses a quick-release clamp. A sealing gasket is provided on the inner side of connector 11, and the edges of the outer sides of the first connecting plate 5 and the second connecting plate 8 are rounded.

[0038] Specifically, quick-connect clamps, as fastening fixtures for rapid pipe connections, achieve quick installation and removal through components such as chucks, clamps, and gaskets, while ensuring a strong and airtight connection. No welding or complex tools are required; the connection can be completed manually, significantly saving time and labor costs. A sealing gasket forms a seal between the connector 11 and the first connecting plate 5 and the second connecting plate 8, improving the sealing effect. The rounded corners of the first connecting plate 5 and the second connecting plate 8 facilitate the installation of the connector 11 onto them.

[0039] The working principle of this utility model is as follows:

[0040] S1. The raw material is added to the machine body 1 from the hopper 2. After the raw material is crushed, the mud is pushed out from the extrusion cylinder 3.

[0041] S2. During the extrusion process, the mud flows from the extrusion cylinder 3 to the conical part 4, and then flows through the conical part 4 into the plug 6 and the conical opening 9. During this process, the flow channel becomes smaller and smaller, and the mud is continuously squeezed and contracted, eventually entering the forming opening 10 from the conical opening 9 for forming and extrusion.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] 1. This continuous extrusion molding device for clay, through the arrangement of a conical section 4, a first connecting plate 5, a second connecting plate 8, a connector 6, a conical opening 9, a molding opening 10, and a connecting piece 11, allows the clay to flow from the extrusion cylinder 3 to the conical section 4 during extrusion. From there, it flows through the conical section 4 into the connector 6 and the conical opening 9. During this process, the flow channel becomes increasingly narrow, and the clay is continuously compressed and contracted, eventually entering the molding opening 10 from the conical opening 9 for molding and extrusion. The extrusion cylinder 3 smoothly delivers the clay to the die 7 through the connector 6 and the conical opening 9, without any jamming caused by the connection of the first connecting plate 5 and the second connecting plate 8. This results in smoother and more continuous clay extrusion, which is beneficial for improving extrusion quality.

[0044] 2. In this continuous extrusion molding device for clay, the first connecting plate 5 and the second connecting plate 8 provide conditions for the connection between the extrusion cylinder 3 and the die 7. A pad 12 is set between the two. After the two are connected, the pad 12 is deformed by compression, sealing the gap between them and ensuring the sealing of the connection. By controlling the inclination angle and length of the conical orifice 9, the clay flows more smoothly from the connector 6 into the conical orifice 9.
