[0033] Reference Figure 1-Figure 3 The cleaning component 5 includes a mounting frame 52, and a connecting block 56 is plugged into the bottom inner wall of the mounting frame 52. By plugging the connecting block 56 with the mounting frame 52, the sponge block 57 is installed on the mounting frame 52. The sponge block 57 is fixedly connected to the bottom of the connecting block 56. The water absorption performance of the sponge block 57 is used to clean the water on the plastic strip. A telescopic rod 53 is hinged on the front side of the support plate 3. The telescopic rod 53 is composed of two sets of sleeves that are mutually sleeved and has the effect of extension and contraction. The two sets of mounting frames 52 are driven to move by the rotation effect of the telescopic rod 53. A slide groove 51 is provided on the front side of the support plate 3. A slider 54 is fixedly connected to the back side of the mounting frame 52. The slider 54 guides the mounting frame 52 to prevent the mounting frame 52 from shifting when moving. A limiting component 58 is provided on the left inner wall of the connecting block 56. The connecting block 56 is limited by the limiting component 58 so that the sponge block 57 remains fixed.

[0034] Reference Figure 1 and Figure 4 The cooling assembly 6 includes a shell 61, the inner wall of the shell 61 is fixedly connected to a water tank 66, and the cooling water is stored through the water tank 66. The inner wall of the shell 61 is fixedly connected to a cooling pipe 67, and the cooling pipe 67 is provided with multiple groups. The cooling water in the water tank 66 is continuously cooled through the cooling pipe 67.

[0035] Reference Figure 2 and Figure 3 The limiting component 58 includes a card block 581, and the right side of the card block 581 is elastically connected to the inner wall of the left side of the connecting block 56 through a spring 582. Through the elastic force of the spring 582, the card block 581 always maintains the card connection effect with the card slot 583 when not affected by external force, thereby limiting the connecting block 56. A card slot 583 is opened on the left side of the installation frame 52.

[0036] Reference Figure 1 and Figure 2 There are two groups of mounting frames 52 distributed alternately. The right side of one group of mounting frames 52 is hinged to the left end of the telescopic rod 53, and the left side of the other group of mounting frames 52 is hinged to the right end of the telescopic rod 53. Through the hinge effect of the telescopic rod 53, when one group of mounting frames 52 moves, it can drive the other group of mounting frames 52 to move in the opposite direction. The inner wall of the slider 54 is threadedly connected with a bolt 55. By screwing the bolt 55, the slider 54 is limited or released.

[0037] Reference Figure 1 and Figure 4 The front of the shell 61 is fixedly connected to the back of the base 1, and the fixing effect of the shell 61 prevents the shell 61 from falling off. The left bottom of the water tank 66 is fixedly connected with a water inlet pipe 64, and the cooling water in the cooling pool 4 is transported to the water tank 66 through the water inlet pipe 64. The right top of the water tank 66 is fixedly connected with a water outlet pipe 65, and the water in the water tank 66 is transported to the cooling pool 4 through the water outlet pipe 65. A first water pump 62 is arranged at the left bottom of the shell 61, and a second water pump 63 is arranged at the right top of the shell 61.

[0038] Reference Figure 3 One end of the spring 582 is fixedly connected to the left inner wall of the connecting block 56, and the other end of the spring 582 is fixedly connected to the right side of the card block 581. The fixing effect of the spring 582 keeps the card block 581 fixed to prevent the card block 581 from falling off. The outer wall of the card block 581 is slidably connected to the left inner wall of the connecting block 56. The sliding effect of the card block 581 allows the card block 581 to be engaged or released from the card slot 583. The outer wall of the card block 581 is engaged with the inner wall of the card slot 583. The engagement effect of the card block 581 and the card slot 583 allows the installation frame 52 to limit the connecting block 56.

[0039] Reference Figure 1 and Figure 4 The outer wall of the slider 54 is slidably connected to the inner wall of the slide groove 51. The sliding effect of the slider 54 drives the installation frame 52 to move. The rear end of the bolt 55 contacts the inner wall of the slide groove 51. The input end of the first water pump 62 is connected to the water inlet pipe 64. By starting the first water pump 62, the water inlet pipe 64 is transported. The output end of the second water pump 63 is connected to the water outlet pipe 65. By starting the second water pump 63, the water outlet pipe 65 is transported.

[0040] Working principle: the staff places the plastic in the extruder 2, extrude the plastic into plastic strips through the extruder 2, pass the plastic strips through the cylindrical rollers provided in the cooling pool 4, and connect them to the wire drawing device provided on the support plate 3. The cooled plastic strips are wiped and cleaned by the sponge block 57, and the extruded plastic strips are cooled by the cooling water in the cooling pool 4. The staff starts the first water pump 62 and the second water pump 63, so that the water outlet pipe 65 transports the cooling water in the water tank 66 to the cooling pool 4, and at the same time, the water inlet pipe 64 transports the cooling water in the cooling pool 4 to the water tank 66, and the water in the cooling pool 4 is circulated and cooled through the cooling pipe 67.

[0041] When the sponge block 57 is used for a long time and the cleaning effect is reduced, the staff can screw the bolt 55 to release the limiting effect of the slider 54, and slide the slider 54 upward along the inner wall of the slide groove 51, so that the installation frame 52 moves upward, and at the same time, the telescopic rod 53 drives the other group of installation frames 52 to move downward, so that the sponge block 57 installed on the other group of installation frames 52 contacts the outer wall of the plastic strip, and the staff can screw the bolt 55 in the reverse direction to limit the slider 54, so that the two groups of installation frames 52 remain fixed.

[0042] The staff presses the card block 581 so that the card block 581 releases the card connection effect with the card slot 583 and releases the limiting effect on the connecting block 56. The staff removes the sponge block 57 to be replaced and inserts the connecting block 56 on the replaced sponge block 57 into the installation frame 52. The card block 581 is carded with the card slot 583 under the elastic force of the spring 582 and the connecting block 56 is limited so that the sponge block 57 is installed in the installation frame 52.
