The extrusion assembly includes a first sleeve and a second sleeve concentrically arranged, a drive motor, a screw, and an extrusion head. A heating chamber is provided between the first sleeve and the second sleeve. The drive motor is connected to both the screw and the controller. The screw passes through the second sleeve and abuts against the inner surface of the second sleeve to form a spiral extrusion channel. The feed cylinder communicates with the spiral extrusion channel, and the screw has a heating groove. The heating assembly includes a first heating wire and a second heating wire. The first heating wire is housed in the heating chamber and spirally wound around the second sleeve, while the second heating wire is housed in the heating groove. However, during the application of this technical solution, the extrusion equipment needs to continuously heat the raw material of the sealing strip, which leads to overheating of the equipment. If workers accidentally touch it, they may be injured, affecting the normal operation of production. There is a technical problem that it is not possible to ensure the normal operation of the extrusion equipment while providing heat insulation protection to ensure the safety of production operations. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an extrusion equipment for producing washing machine sealing strips, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an extrusion equipment for producing sealing strips for washing machines, comprising a machine base, and further comprising: a cylinder at the top of the machine base, an inner cylinder inside the cylinder, a heater between the inner side of the cylinder and the outer side of the inner cylinder, a geared motor on one side of the cylinder, an extrusion die on the other side of the cylinder, a feed hopper inserted into one side between the top of the cylinder and the top of the inner cylinder, a feeding mechanism inside the feed hopper, a first sealing bushing passing through the middle position between one side of the inner cylinder and one side of the inner cylinder, an extrusion auger at the middle position between the two sides of the inner cylinder, a protective cover on the outside of the cylinder, positioning slots at both ends of the top of the machine base, mounting plates at the bottom of both ends inside the protective cover, a through groove at the top of the protective cover, a snap-fit ​​stud on one side of the top of the mounting plate, a fastening nut fitted onto the top of the snap-fit ​​stud, a positioning slot on one side of the top of the positioning slot, and a cooling assembly on the top of one side of the machine base.

[0007] Furthermore, the protective cover has a U-shaped vertical cross-section, the through slots are arranged at equal intervals at the top of the protective cover, and the positioning slots are symmetrically arranged on the top of the machine.

[0008] Furthermore, the mounting plate is inserted into the interior of the positioning slot, and the snap-fit ​​stud is snapped into the inner side of the positioning slot.

[0009] Furthermore, the feeding mechanism includes a servo motor, which is located at the middle position of the top of the feeding hopper. A second sealing bushing is connected to the middle position of the top of the inside of the feeding hopper. A spiral shaft is provided inside the feeding hopper, and the top end of the spiral shaft passes through the second sealing bushing and is connected to the output end of the servo motor.

[0010] Furthermore, one side of the extrusion auger is connected to the output end of the first sealing bushing and the reduction motor, and the extrusion die is connected to the inner cylinder.

[0011] Furthermore, the cooling assembly includes a frame, which is located on the top of one side of the machine platform. An operation window is provided on the top of the inner side of the frame. A negative pressure fan is installed on the top of the rear end of the frame. A ventilation slot is provided at the front end of the frame near the top.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model provides a protective component on the outside of the drum. Before the extrusion of the washing machine sealing strip, the mounting plate is inserted into the positioning slot, and the locking stud is inserted into the positioning slot. Then, the fastening nut is fitted onto the outside of the locking stud and tightened. This achieves the purpose of securely installing the protective cover on the outside of the drum at the top of the machine. When the equipment is running, the protective cover isolates the drum, preventing the operator from accidentally touching and injuring the operator due to overheating.

[0014] 2. This utility model has a cooling component installed on the top of one side of the machine. When in use, after the washing machine sealing strip is extruded from the extrusion die, the negative pressure fan is activated to exhaust the air inside the frame to the outside. At the same time, external air is drawn in through the operation window and ventilation slot, thereby accelerating the air flow rate inside the frame. This allows the heat of the washing machine sealing strip that passes through the frame after extrusion to be quickly carried away, achieving the purpose of initial cooling of the washing machine sealing strip, shortening the time required for subsequent cooling, further improving the production efficiency of the washing machine sealing strip, and thus correspondingly reducing the production cost of the washing machine sealing strip.

After the raw material for the washing machine sealing strip is put into the feed hopper 4, the servo motor 5 is started to drive the spiral shaft 16 to rotate and evenly transport the raw material into the inner drum 19. The first sealing sleeve 14 is installed in the middle position between one side of the inner drum 2 and the middle position between the two sides of the inner drum 19. The extrusion auger 15 is installed in the middle position between the two sides of the inner drum 19. One side of the extrusion auger 15 passes through the first sealing sleeve 14 and is connected to the output end of the reduction motor 3. After the raw material is transported into the inner drum 19, the heater 18 is turned on to heat the raw material to a molten state. Then the reduction motor 3 is started to drive the extrusion auger 15 to rotate and move the molten raw material to the side of the extrusion die 12 and extrude it into a sealing strip.

[0024] As a further implementation of this embodiment, such as Figure 1-4As shown, a protective cover 6 is provided on the outside of the cylinder 2. The vertical cross-section of the protective cover 6 is U-shaped. Positioning slots 13 are provided at both ends of the top of the machine base 1. The positioning slots 13 are symmetrically arranged on the top of the machine base 1. Mounting plates 22 are provided at the bottom of both ends inside the protective cover 6. The mounting plates 22 are inserted into the interior of the positioning slots 13. A through groove 7 is provided at the top of the interior of the protective cover 6. The through grooves 7 are arranged at equal intervals at the top of the interior of the protective cover 6. A snap-fit ​​stud 20 is provided on one side of the top of the mounting plate 22. A positioning slot 21 is provided on one side of the top of the interior of the positioning slot 13. The snap-fit ​​stud 20 is snapped into place. Inside the positioning slot 21, a fastening nut 23 is fitted on the top of the snap-fit ​​stud 20. After the snap-fit ​​mounting plate 22 and the snap-fit ​​stud 20 are in place, the fastening nut 23 is fitted onto the outside of the snap-fit ​​stud 20 and tightened to achieve the purpose of firmly installing the protective cover 6 on the outside of the top cylinder 2 of the machine platform 1. Thus, the cylinder 2 can be isolated by the protective cover 6 to prevent the cylinder 2 from overheating and causing injury to the operator. The through slot 7 can ensure the normal heat dissipation of the equipment, thereby achieving the purpose of ensuring the normal operation of the extrusion equipment while ensuring the safety of the workers, and improving the safety of the extrusion process of the washing machine sealing strip.

[0025] Insert the mounting plate 22 into the inside of the positioning slot 13, and snap the stud 20 into the inside of the positioning slot 21. Then, put the fastening nut 23 on the outside of the snap stud 20 and tighten it. The protective cover 6 can be firmly installed on the outside of the top cylinder 2 of the machine base 1. When the equipment is running, the protective cover 6 isolates the cylinder 2 to prevent the cylinder 2 from overheating and causing accidental injury to the operator. The through slot 7 can also ensure normal heat dissipation of the equipment.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a cooling assembly is provided on the top of one side of the machine base 1. The cooling assembly includes a frame 8, which is located on the top of one side of the machine base 1. An operation window 10 is provided on the top of the inner side of the frame 8. A negative pressure fan 9 is installed on the top of the rear end of the frame 8. After the washing machine sealing strip is extruded from the extrusion die 12, the negative pressure fan 9 is activated to exhaust the air inside the frame 8 to the outside. A ventilation slot 11 is provided at the front end of the frame 8 near the top. At the same time, external air is drawn in from the operation window 10 and the ventilation slot 11, thereby accelerating the airflow speed inside the frame 8. This allows the heat of the washing machine sealing strip that passes through the inner side of the frame 8 after extrusion to be quickly carried away, achieving the purpose of initial cooling of the washing machine sealing strip, shortening the time required for subsequent cooling, further improving the production efficiency of the washing machine sealing strip, and thus correspondingly reducing the production cost of the washing machine sealing strip.

[0027] Working principle: When using the extrusion equipment, first insert the mounting plate 22 into the positioning slot 13 and snap the locking stud 20 into the positioning groove 21. Then, put the fastening nut 23 on the outside of the locking stud 20 and tighten it. This will securely install the protective cover 6 on the outside of the top cylinder 2 of the machine base 1. After the processing starts, the raw material for the washing machine sealing strip is put into the feed hopper 4, and the servo motor 5 is started to drive the spiral shaft 16 to rotate, so that the raw material is evenly transported into the inner cylinder 19. At the same time, the heater 18 is turned on to heat the raw material to a molten state. Meanwhile, the protective cover 6 isolates the cylinder 2. To prevent workers from accidentally touching and injuring themselves by overheating the drum 2, and to ensure proper heat dissipation of the equipment using the through groove 7, the geared motor 3 is then started to drive the extrusion auger 15 to rotate, moving the molten raw material toward the extrusion die 12 and extruding it into a sealing strip. After the washing machine sealing strip is extruded from the extrusion die 12, the negative pressure fan 9 is started to exhaust the air inside the frame 8 to the outside. At the same time, external air is drawn in from the operating window 10 and the ventilation groove 11, thereby accelerating the airflow inside the frame 8. This allows the heat of the washing machine sealing strip that passes through the inside of the frame 8 after extrusion to be quickly carried away, thus initially cooling the washing machine sealing strip.
