Description

Technical Field

[0001] The utility model relates to the field of extruders, and more particularly to a feeding structure and an extruder. Background Art

[0002] Extruders are a type of plastics machinery that originated in the 18th century. Extruder heads can be categorized as either right-angle or bevel-angle, depending on the direction of material flow and the angle between the screw centerline. During operation, material is conveyed to a silo and continuously fed during the extrusion process, effectively processing plastics and other materials.

[0003] In some known technical solutions, when the extruder is in use, it is sometimes necessary to seal the silo, so that the quality of the material delivered to the silo cannot be understood, resulting in poor quality of the processed product and reduced product quality.

[0004] Therefore, we propose a material feeding structure and an extruder to solve the above problems. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a feeding structure that solves the problem that the quality of the material entering the extruder cannot be effectively and timely observed when the silo is sealed.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions.

[0007] A feeding structure includes a silo;

[0008] A material discharge part, installed below the silo;

[0009] A sampling tube is provided on the discharge portion, with one end of the sampling tube located inside the discharge portion and communicating with the inner cavity of the discharge portion, and the other end located outside the discharge portion and tilted downward, so that the material in the discharge portion flows out along the sampling tube;

[0010] The sealing part is detachably mounted on the tube mouth of the sampling tube and is sealed with the sampling tube.

[0011] In one embodiment, a plug plate is movably disposed between the silo and the unloading portion;

[0012] A feeding port is provided on the plug plate, and the plug plate is configured to switch between a first working state and a second working state;

[0013] When the insert plate is in the first working state, the silo is connected to the discharge part, so that the material flows from the silo into the discharge part;

[0014] When the inserting plate is in the second working state, the silo and the discharge part are closed, so that the material stops flowing from the silo into the discharge part.

[0015] In one embodiment, the feeding structure further includes: a limiting portion, located on the side wall of the inserting plate in the movable direction, and configured so that when the inserting plate is in the first working state, the limiting portion is in contact with the side wall of the blanking portion.

[0016] In one embodiment, the blanking portion includes an upper opening and a lower opening;

[0017] The cross-sectional area of the upper opening is smaller than the cross-sectional area of the lower opening.

[0018] In one embodiment, the silo includes a cylindrical portion and a frustum portion;

[0019] The opening of one end of the truncated cone portion away from the cylindrical portion is smaller, and the height of the truncated cone portion is higher than the height of the cylindrical portion.

[0020] In one embodiment, the feeding structure further comprises:

[0021] A movable opening is provided on the blanking portion and is used to provide a movable space for the inserting plate;

[0022] The connection between the discharge part and the silo is sealed all around.

[0023] In one embodiment,

[0024] The moving direction of the inserting plate is located on the same side as the sampling tube.

[0025] An extruder comprises an extruder body and the above-mentioned feeding structure.

[0026] In one embodiment, the extruder further includes a feed port, which is communicated with the discharge portion and is used to transport the material from the discharge portion into the extruder body.

[0027] In one embodiment, the extruder further comprises a material delivery pipe, which is in communication with the silo and is used for delivering the material into the silo.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] A sampling tube is installed on the feeding section. When sampling is needed, the sealing section is removed, and the material flows out of the sampling tube, making sampling convenient. After sampling is completed, the sealing section can be resealed without affecting the feeding. This makes it easy to observe the quality of the feeding material and improve the processing quality of the product.

[0030] By setting up a plug plate, it is convenient to block the falling of materials. When it is found that the quality of the material is deteriorating, the plug plate can be used to block the discharge part, and the material will be retained in the silo and will not fall into the extruder.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0043] This embodiment solves the problem that the quality of materials cannot be observed in time in the sealed silo 1 by providing a feeding structure. When in use, it is possible to quickly sample the discharged materials, observe the quality, and test the quality to ensure that the produced products are better.

[0044] The technical solution in this embodiment is to solve the above technical problems, and the overall idea is as follows:

[0045] An opening is opened on one side of the discharge part 2, and a sampling tube 3 is installed on the opening, so that the material can flow out along the sampling tube 3, which is convenient for sampling. The tube mouth of the sampling tube 3 is sealed, and the sealing part 4 can be removed. In this way, it can be removed when sampling is needed, and blocked when sampling is not needed, which will not affect the normal discharge process.

[0046] See also Figure 1-Figure 5 A feeding structure includes a silo 1; a discharge part 2, installed below the silo 1; a sampling tube 3, arranged on the discharge part 2, and the sampling tube 3 is inclined downward so that the material in the discharge part 2 flows out along the sampling tube 3; a sealing part 4, detachably installed at the tube mouth of the sampling tube 3, and sealed with the sampling tube 3.

[0047] Reference Figure 5 Silo 1 is equipped with a sealing cover to prevent material leakage. The discharge section 2 is rounded on the top and square on the bottom, ensuring a stable and rapid material drop. A sampling tube 3 communicates with the inner cavity of the discharge section 2. The upper end of the sampling tube 3 extends into the discharge section 2, while the lower end of the sampling tube 3 extends downwardly to the outside of the discharge section 2, allowing material to flow out through the sampling tube 3. The sealing section 4 and the sampling tube 3 can be connected by threads or snaps, ensuring that the inner wall of the sealing section 4 contacts and seals the sampling tube 3.

[0048] Reference Figure 2 and Figure 3 The inserting plate 5 is movably arranged between the hopper 1 and the unloading part 2; in this way, the inserting plate 5 can be movable, and its position can be changed by pushing the inserting plate 5. It can be pushed manually or by other devices such as a hydraulic cylinder, an electric telescopic rod, etc.

[0049] The discharge port 501 is opened on the insert plate 5, and the insert plate 5 is set to switch between the first working state and the second working state; the size of the discharge port 501 is set to match the size of the upper opening 201 of the discharge part 2 so that the material can quickly enter the discharge part 2.

[0050] When the insert plate 5 is in the first working state, the silo 1 is connected to the discharge part 2, so that the material flows from the silo 1 into the discharge part 2; in this way, the material can smoothly flow from the silo 1 into the discharge part 2, so that the entire extrusion process proceeds smoothly.

[0051] When the insert plate 5 is in the second working state, the silo 1 and the discharge part 2 are sealed, so that the material stops flowing from the silo 1 into the discharge part 2. After the material is sealed, sampling can be carried out, and the discharge can also be stopped. In this way, if the quality of the material is found to be deteriorating, the feeding can be stopped to prevent the material in the silo 1 from continuing to fall and affecting the quality of the processed product.

[0052] The limiting portion 502 is located on the side wall of the inserting plate 5 in the movable direction, and is configured so that when the inserting plate 5 is in the first working state, the limiting portion 502 is in contact with the side wall of the blanking portion 2 .

[0053] The provided limiting portion 502 can accurately position the inserting plate 5, ensuring that after the inserting plate 5 reaches the preset position, the communication between the silo 1 and the unloading portion 2 is in the smoothest state.

[0054] Reference Figure 4 The material discharge portion 2 includes an upper opening 201 and a lower opening 202; the cross-sectional area of the upper opening 201 is smaller than the cross-sectional area of the lower opening 202. In this way, the material falls faster in the material discharge portion 2, avoiding material blockage.

[0055] The silo 1 includes a cylindrical portion 101 and a conical portion 102 ; the conical portion 102 has a smaller opening at one end away from the cylindrical portion 101 , and the height of the conical portion 102 is higher than that of the cylindrical portion 101 .

[0056] The cylindrical portion 101 is mainly used to store materials, while the frustum portion 102 is configured such that the sidewall of the frustum portion 102 has a larger inclination angle, allowing the material to fall more quickly.

[0057] The feeding structure further includes a movable opening 203 located at the upper end of the discharge part 2 for providing a movable space for the inserting plate 5. To prevent material from overflowing, the connection between the discharge part 2 and the silo 1 is sealed around.

[0058] The movable opening 203 can provide space for the inserting plate 5 to move back and forth, and also prevent the inserting plate 5 from being too tightly connected with the discharge part 2 and the silo 1. The connection between the discharge part 2 and the silo 1 can ensure that the material will not leak from the connection and will not affect the normal discharge process.

[0059] Furthermore, in order to facilitate the sampling process and enable the staff to work on one side of the extruder, the moving direction of the insert plate 5 is located on the same side as the sampling tube 3.

[0060] In this way, the inserting plate 5 does not need to be moved to other sides during the pulling process, and samples can be quickly taken through the sampling tube 3, which is convenient for operation. Example

[0061] Reference Figure 1 This embodiment solves the problem that the quality of the material extruded by the extruder cannot be guaranteed in a timely and effective manner by providing an extruder, and when used, it achieves the improvement of the yield and quality rate of the product.

[0062] The technical solution in this embodiment is to solve the above technical problems, and the overall idea is as follows:

[0063] An opening is opened on one side of the discharge part 2, and a sampling tube 3 is installed on the opening, so that the material can flow out along the sampling tube 3, which is convenient for sampling. The tube mouth of the sampling tube 3 is sealed, and the sealing part 4 can be removed. In this way, it can be removed when sampling is needed, and blocked when sampling is not needed, which will not affect the normal discharge process.

[0064] An extruder comprises an extruder body 6 and the above-mentioned feeding structure.

[0065] The extruder further includes a feed port 7 , which is in communication with the discharge portion 2 and is used for conveying the material in the discharge portion 2 into the extruder body 6 .

[0066] The extruder further comprises a feeding pipe 8, which is in communication with the silo 1 and is used for conveying the material into the silo 1. The feeding pipe 8 can be in communication with the silo 1 during conveying without affecting the sealing of the silo 1.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
