DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 , an embodiment provided by the present invention: an extruder capable of reducing the deformation of the discharged material, including a processing table 1. On the left side of the upper surface of the processing table 1, an extruder body 2 is fixedly connected. On the right end of the extruder body 2, an extrusion die head 3 is fixedly connected. After adding raw materials into the interior of the extruder body 2, the raw materials can be extruded and formed through the extrusion die head 3. On the right side of the upper surface of the processing table 1, a water tank 4 is fixedly connected. At the bottom of the water tank 4, a drain pipe (not directly shown in the figure) is fixedly connected. The bottom end of the drain pipe penetrates through the processing table 1, and a solenoid valve is fixedly connected to the outer side. The water flow inside the water tank 4 can be replaced by opening the drain pipe.

[0033] Referring to Figures 2 - 4 , a through hole 5 is opened on the left side surface of the water tank 4. The extruded product can enter the water tank 4 through the through hole 5 for cooling treatment. On the right side surface of the extrusion die head 3, a fixed pipe 6 is fixedly connected. The fixed pipe 6 penetrates through the through hole 5. When the product enters the interior of the through hole 5, it will be sleeved on the outer side of the fixed pipe 6. The right end of the fixed pipe 6 is arranged in an open structure, which can increase the contact area between the fixed pipe 6 and the cold water, thereby improving the cooling efficiency of the product. When the product moves to the right through the fixed pipe 6, both the inner and outer walls can be quickly cooled, improving the efficiency of cooling and forming.

[0034] A sleeve rod 7 is arranged on the right side of the fixed pipe 6. The diameter of the sleeve rod 7 is the same as that of the fixed pipe 6. The left end of the sleeve rod 7 is arranged in a pointed structure. When the right end of the product passes through the fixed pipe 6, it will be sleeved on the outer side of the sleeve rod 7 along the inclined surface at the left end of the sleeve rod 7. When the sleeving is completed, the interior of the product will be filled with cold water, and these cold waters will support the interior of the product at this time. A moving unit is arranged on the right side of the sleeve rod 7. The moving unit includes a fixing plate 71. The fixing plate 71 is fixedly connected inside the water tank 4. On the left side surface of the fixing plate 71, an electric push rod 72 is fixedly connected. The left end of the electric push rod 72 is fixedly connected to the right end of the sleeve rod 7. When the electric push rod 72 is started, it can drive the sleeve rod 7 to perform a linear motion in the left-right direction, and further drive the cut product to move synchronously.

[0035] Above the right side of the fixed tube 6, there is a cutting unit. The cutting unit includes a fixed frame 101 which is fixedly connected to the upper surface of the water tank 4. The inner top surface of the fixed frame 101 is fixedly connected with a lifting cylinder 102. The bottom end of the lifting cylinder 102 is fixedly connected with a conical block 103. When the lifting cylinder 102 is started, it can drive the conical block 103 to perform linear motion in the up and down directions. The bottom of the conical block 103 is fixedly connected with a cutting knife 104. When the lifting cylinder 102 is started, it can drive the cutting knife 104 to perform linear motion in the up and down directions. When moving downward, the inclined surface at the bottom end of the conical block 103 can break the water flow, reducing the resistance to the movement of the lifting cylinder 102 by the cold water, thereby reducing the load of the lifting cylinder 102 and enhancing the service life of the lifting cylinder 102. The left side surface of the cutting knife 104 is in mutual contact with the right side surface of the fixed tube 6. When the cutting knife 104 moves downward, it can cut the part of the product passing through the fixed tube 6. During the cutting process, the cold water that enters the product when it is sleeved on the sleeve rod 7 can support the inside of the product, thereby reducing the deformation caused by the downward movement of the cutting knife 104 when cutting the product, and avoiding the shrinkage of the opening of the product, which may affect its use.

[0036] Refer to Figure 5 , a push ring 8 is sleeved on the outer side of the sleeve rod 7. The outer side of the push ring 8 is fixedly connected with a connecting rod 9. One end of the connecting rod 9 away from the push ring 8 is fixedly connected with the inner wall of the water tank 4. After the product is cut, the electric push rod 72 can be started to drive the sleeve rod 7 to move to the right. During the movement, the push ring 8 will push the product cut off and sleeved on the outer side of the sleeve rod 7, so that it can be separated from the sleeve rod 7, facilitating the discharging of the material.

[0037] Refer to Figure 2 , a sloping platform 11 is fixedly connected to the left side inside the water tank 4. When the cut-off product is pushed off the sleeve rod 7, it will fall onto the sloping platform 11 and slide to the right along the inclined surface of the sloping platform 11. A collection box 12 is arranged on the right side inside the water tank 4. The outer wall of the collection box 12 is in mutual contact with the inner wall of the water tank 4. The left side surface of the collection box 12 is in mutual contact with the right side surface of the sloping platform 11. The product sliding down from the sloping platform 11 can completely enter the collection box 12 for collection, which is convenient for unified processing. A water leakage hole 13 is opened on the bottom surface of the collection box 12. A handle 14 is fixedly connected to the upper surface of the collection box 12. After the collection box 12 is filled with products, the collection box 12 can be lifted upward through the handle 14. The water flow inside the collection box 12 can be discharged downward through the water leakage hole 13, so that the collection box 12 can take out all the products from the water tank 4, which is convenient for subsequent processing and can improve the processing efficiency.

[0038] Working principle: After adding raw materials into the interior of the extruder body 2, the raw materials will be extruded and formed through the extrusion die head 3. The extruded product will enter the interior of the through hole 5 and sleeve on the outer side of the fixed pipe 6 and move to the right. When the product sleeves on the outer side of the fixed pipe 6 and moves to the right, the cold water in the water tank 4 and the cold water in the fixed pipe 6 can simultaneously perform rapid heat absorption and cooling treatment on the inner and outer walls of the product, accelerating the cooling efficiency of the product. When the right end of the product passes through the fixed pipe 6, it will sleeve on the outer side of the sleeve rod 7 along the inclined surface at the left end of the sleeve rod 7. When the sleeving is completed, the interior of the product will be filled with cold water. When the length of the product passing through the fixed pipe 6 reaches the required value, the lifting cylinder 102 can be started to drive the cutting knife 104 to move downward to cut the product. When cutting, the cold water entering the product can support the interior of the product, thereby reducing the deformation caused by the downward movement of the cutting knife 104 when cutting the product. After cutting, the electric push rod 72 is started to drive the sleeve rod 7 to move to the right, so that the push ring 8 pushes the product off the sleeve rod 7, and the product slides down along the inclined surface of the inclined table 11 and enters the collection box 12 for unified collection and storage.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
