Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding cylinder technology, and specifically to a protective structure inside a side feeding cylinder. Background Technology
[0002] The side feed barrel is a special barrel component of a twin-screw extruder. Its core design is to open the side of the barrel, which allows for the precise addition of solid or liquid additives to the molten material during the extrusion process. It is a key structure to ensure the processing requirements of compound materials.
[0003] In practical applications, the twin screws inside the side feed barrel need to rotate continuously at high speed to achieve material conveying. When processing raw materials with high resistance, the friction between the screw and the raw material, and between the raw material and the inner wall of the barrel, will be significantly aggravated, causing the side feed barrel to heat up rapidly and the temperature to rise excessively. Excessive temperature will directly damage the physical and chemical stability of the raw material and affect the processing quality of the final product.
[0004] To address the aforementioned issues, this application proposes a protective structure for the inside of a side-feeding cylinder. Utility Model Content
[0005] This utility model addresses the technical problems existing in the prior art by providing a protective structure inside a side-feeding cylinder.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a protective structure inside a side feeding cylinder, wherein the side feeding cylinder includes a cylinder body and the cylinder body has an opening; The protective structure includes a temperature control component; The temperature control component includes two mounting slots on the cylinder body. The cylinder body has two through-holes that communicate with the two mounting slots. A heat circulation pipe is detachably mounted on the cylinder body through both mounting slots. The two ends of the heat circulation pipe are connected to a connecting pipe. A delivery pipe connects the two connecting pipes. A circulation pump is installed on the delivery pipe. The circulation pump is installed at the bottom of the cylinder body. A cooling pipe is installed on the delivery pipe. A heat-conducting pipe is sleeved on the outside of the cooling pipe. Heat dissipation fins are installed on the heat-conducting pipe. A cooling fan is installed at the bottom of the cylinder body. The air outlet of the cooling fan faces the heat dissipation fins.
[0007] The cylinder body is provided with an operating port that communicates with the mounting groove and the through-hole. By providing the operating port, it is convenient to operate the connection between the heat circulation pipe and the connecting pipe.
[0008] The cylinder is fitted with a positioning block through an installation slot. One side of the positioning block is adapted to the outer side of the heat circulation pipe. A fixing plate is installed on one side of the positioning block. A screw is movably inserted into the fixing plate and threadedly connected to the cylinder. The positioning block, fixing plate, and screw facilitate the assembly and disassembly of the heat circulation pipe.
[0009] The fixing plate has a storage slot, and the screw is located in the storage slot. By setting the storage slot to store the screw head, the possibility of the operator being scratched by the screw head is reduced.
[0010] Both ends of the connecting pipe are threaded with threaded rings, and the two threaded rings are respectively threaded to the connecting end of the corresponding heat circulation pipe. The threaded rings are used to connect the heat circulation pipe and the connecting pipe.
[0011] A temperature control switch is installed on the cooling tube. The temperature sensing end of the temperature control switch is located inside the cooling tube. The temperature control switch is electrically connected to the cooling fan. The temperature control switch is used to control the opening and closing of the cooling fan.
[0012] The temperature control switch includes a temperature sensing module, a pre-temperature module, and a switching module; the cooling fan includes a receiving module. The specific operation methods of the temperature control switch and the cooling fan are as follows: S1, Temperature sensing module: used to receive the temperature Q degrees Celsius of the coolant in the cooling pipe; S2, Pre-temperature module: used to preset the threshold range value: X+Y degrees Celsius; S3, Switch Module: Used to compare the pre-temperature module and the temperature sensing module. If Q≤X, then send a command to the receiving module to keep the cooling fan off until Q>X+Y; If Q > X + Y, then send a signal to the receiving module to keep the cooling fan running, and Q ≤ X; S4, Receiver Module: Used to receive signals from the switch module and execute those signals to control the opening and closing of the cooling fan.
[0013] The beneficial effects of this utility model are: By setting up a temperature control component and starting the circulation pump, the coolant circulates within the hot circulation pipe, connecting pipe, delivery pipe, and cooling pipe. By activating the cooling fan, the coolant flowing in the cooling pipe is cooled, achieving the effect of cooling the cylinder through coolant circulation. This minimizes the rapid heating and excessive temperature rise of the side feed cylinder, which can directly damage the physicochemical stability of the raw materials and affect the processing quality of the final product. The temperature inside the cooling pipe is detected by the temperature control switch, which then controls the activation and deactivation of the cooling fan, making it easier to control the temperature of the circulating coolant.

It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0019] Reference Figures 1-3 A protective structure for a side-feeding cylinder is disclosed. The side-feeding cylinder includes a cylinder body 1 with an opening 101. The opening 101 is an important component of the cylinder body 1, used for the insertion and rotation of a twin-screw, which is existing technology. The protective structure includes a temperature control component 2, which includes two mounting slots 201 on the cylinder body 1 and two through-holes 202 on the cylinder body 1 that communicate with the two mounting slots 201. A heat circulation pipe 203 is detachably mounted on the cylinder body 1 through the two mounting slots 201. The two ends of the heat circulation pipe 203 are connected to a connecting pipe 204. A conveying pipe 206 is connected between the two connecting pipes 204. A circulation pump 207 is mounted on the conveying pipe 206 at the bottom of the cylinder body 1. A cooling pipe 208 is mounted on the conveying pipe 206, and a heat-conducting pipe 209 is sleeved on the outside of the cooling pipe 208. The heat-conducting pipe 209 is spot-welded to the surface of the cylinder body 1. The heat pipe 209 is supported by a heat dissipation fin 210. A cooling fan 211 is installed at the bottom of the cylinder 1, with the air outlet of the cooling fan 211 facing the heat dissipation fin 210. By starting the circulation pump 207, the coolant in the heat circulation pipe 203 is drawn, so that the coolant circulates in the heat circulation pipe 203, the connecting pipe 204, the conveying pipe 206, and the cooling pipe 208. By starting the cooling fan 211, air is blown onto the heat dissipation fin 210, thereby cooling the heat dissipation fin 210, and then cooling the heat pipe 209, and then cooling the cooling pipe 208. This cools the coolant flowing in the cooling pipe 208, achieving the effect of cooling the cylinder 1 by circulating the coolant. This achieves the goal of avoiding rapid heating of the side feed cylinder and excessive temperature rise, which would directly damage the physical and chemical stability of the raw materials and affect the processing quality of the final product. Among them, the circulating pump 207 is a model TA60E manufactured by Changsha Tops Industrial Technology Co., Ltd.
[0020] Reference Figure 2The cylinder 1 has an operating port 217 that communicates with the mounting groove 201 and the through port 202. The operating port 217 facilitates the operator to assemble and disassemble the heat circulation pipe 203 and the connecting pipe 204. Both ends of the connecting pipe 204 are threaded with threaded rings 205. The two threaded rings 205 are respectively threaded to the connecting end of the corresponding heat circulation pipe 203. The threaded rings 205 are used to connect the heat circulation pipe 203 and the connecting pipe 204.
[0021] Reference Figure 3 and Figure 4 The cylinder 1 is fitted with a positioning block 212 through the mounting groove 201. One side of the positioning block 212 is adapted to the outer side of the heat circulation pipe 203. A fixing plate 213 is installed on one side of the positioning block 212. A screw 214 is movably inserted on the fixing plate 213. The screw 214 is threadedly connected to the cylinder 1. The heat circulation pipe 203 can be disassembled and assembled by using the positioning block 212 in conjunction with the screw 214.
[0022] The fixing plate 213 has a storage slot 215, and the screw 214 is located in the storage slot 215. The storage slot 215 is used to place the screw head of the screw 214 to avoid the screw head scratching the operator as much as possible.
[0023] Reference Figures 5-6 A temperature control switch 216 is installed on the cooling tube 208. The temperature sensing end of the temperature control switch 216 is located inside the cooling tube 208. The temperature control switch 216 is electrically connected to the cooling fan 211. The temperature control switch 216 includes a temperature sensing module, a preheating module, and a switching module. The cooling fan 211 includes a receiving module. The specific operation methods of the temperature control switch 216 and the cooling fan 211 are as follows: S1, Temperature sensing module: used to receive the temperature Q of the coolant inside the cooling pipe 208; S2, Preheating Module: Used to preset the threshold range value: X+Y degrees Celsius, where X is the optimal temperature and Y is any temperature. Y needs to be set reasonably according to the operator. S3, Switch Module: Used to compare the pre-temperature module and the temperature sensing module. If Q≤X, then send a signal command to the receiving module to keep the cooling fan 211 off until Q>X+Y; If Q > X + Y, then a signal is sent to the receiving module to keep the cooling fan 211 running, and Q ≤ X; S4, Receiver module: Used to receive signals from the switch module and execute those signals to control the opening and closing of the cooling fan 211.
[0024] Working principle: The protective structure inside the side feed cylinder works by activating the circulation pump 207, which draws coolant from the hot circulation pipe 203. This causes the coolant to circulate within the hot circulation pipe 203, connecting pipe 204, conveying pipe 206, and cooling pipe 208. Activating the cooling fan 211 blows air onto the heat dissipation fins 210, thereby cooling the heat conduction pipe 209, and subsequently the cooling pipe 208. This cooling process cools the coolant flowing within the cooling pipe 208, achieving a cooling effect through coolant circulation and thus lowering the temperature of the cylinder 1. This approach minimizes the risk of rapid heating and excessive temperature rise in the side feed cylinder, which can directly damage the physicochemical stability of the raw materials and affect the final product's processing quality.
[0025] The protective structure inside the feed cylinder on this side obtains the temperature inside the cooling pipe 208 through the temperature control switch 216, and makes a judgment to control the opening and closing of the cooling fan 211, thereby achieving the effect of more easily controlling the temperature of the circulating coolant.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
