Description

Technical Field

[0001] This utility model relates to a bottom-cutting cross-cutting machine. Background Technology

[0002] Currently, a cross-cutting machine is a device used in extrusion production lines to cut manufactured products to a fixed length. After being extruded from the mold, the product is cooled and then pulled out by a traction machine. When the product is pushed out of the traction machine, it is already in a formed state. At this point, the saw blade in the cross-cutting machine needs to cut the product to a fixed length. For example, Chinese patent CN214818903U discloses a PVC cross-cutting machine. However, when cutting some thick and hard products, the saw blade will heat up due to intense friction. Existing cross-cutting machines lack a structure to cool the saw blade, which leads to excessively high saw blade temperature after continuous cutting. High temperature causes a decrease in the cutting quality of the saw blade and a shortened saw blade life. Utility Model Content

[0055] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0056] like Figures 1-6 As shown, a bottom-cutting cross-cutting machine includes a cutting motor 1, a saw blade 2, a protective cover 3, a water supply tank 4, a water receiving tank 5, and a cooling pump 6.

[0057] The saw blade 2 is connected to the cutting motor 1 so that the cutting motor 1 drives the saw blade 2 to rotate;

[0058] The protective cover 3 covers the outside of the saw blade 2. The upper end of the protective cover 3 has a chip inlet 7, and the lower end of the protective cover 3 has a discharge outlet 8. The upper end of the saw blade 2 is used to extend from the chip inlet 7 to the outside of the protective cover 3 and to retract from the chip inlet 7 into the protective cover 3.

[0059] The water supply tank 4 is used to receive and store cooling water;

[0060] The outlet of the cooling pump 6 is connected to the protective cover 3 through a pipeline. The cooling pump 6 is also connected to the water supply tank 4 and is used to pump the cooling water in the water supply tank 4 to the protective cover 3 for cooling the saw blade 2.

[0061] The water receiving tank 5 is located below the protective cover 3 and is used to catch the chips and cooling water falling from the outlet 8 of the protective cover 3.

[0062] Specifically, when the upper end of the saw blade 2 extends from the chip inlet 7 to the outside of the protective cover 3, it can cut the product. The chips generated from cutting the product fall into the protective cover 3 from the chip inlet 7. The cooling pump 6 is used to pump cooling water from the water supply tank 4 into the protective cover 3 so that the cooling water is sprayed onto the saw blade 2. Then, the cooling water pumped into the protective cover 3 is discharged together with the chips from the outlet 8 at the lower end of the protective cover 3 and is collected by the water receiving tank 5. By pumping water from the cooling pump 6 and spraying it onto the saw blade 2, the saw blade 2 can be effectively cooled and cooled down, which can prevent the temperature of the saw blade 2 from becoming too high, thereby helping to ensure the cutting quality of the saw blade 2 and extend the service life of the saw blade 2. The outlet of the cooling pump 6 is connected to the inlet 9 on the protective cover 3 through a pipeline.

[0063] like Figures 1-8 As shown, the bottom-cutting cross-cutting machine may also include a base frame 10, a movable frame 11, a transverse shift seat 12, a lifting seat 13, a lifting drive mechanism 14, a transverse shift drive mechanism 15, a reset drive component 16, and a pressing mechanism 17.

[0064] The movable frame 11 is slidably connected to the base frame 10 in the front-to-back direction, and the movable frame 11 has a cutting platform 18 for supporting the product moving forward;

[0065] The pressing mechanism 17 is connected to the movable frame 11. The pressing mechanism 17 is located above the cutting platform 18 and is used to press the forward-moving product onto the cutting platform 18, thereby making the entire movable frame 11 move forward synchronously with the product.

[0066] The transverse sliding seat 12 is slidably connected to the moving frame 11 in the left-right direction, the lifting seat 13 is slidably connected to the transverse sliding seat 12 in the up-down direction, the cutting motor 1 is connected to the lifting seat 13 and located below the cutting platform 18, the protective cover 3 is connected to the transverse sliding seat 12 and covers the outside of the saw blade 2, and the cutting platform 18 is provided with a cutting groove 19 located above the saw blade 2.

[0067] The lifting drive mechanism 14 is connected to the transverse seat 12 and the lifting seat 13, and is used to drive the lifting seat 13 to move up and down, thereby driving the cutting motor 1 and the saw blade 2 to move up and down. When the lifting drive mechanism 14 drives the lifting seat 13 to rise to the position, the upper end of the saw blade 2 extends out of the chip inlet 7 to the outside of the protective cover 3 and passes upward through the cutting groove 19. When the lifting drive mechanism 14 drives the lifting seat 13 to descend to the position, the upper end of the saw blade 2 exits the cutting groove 19 and retracts into the protective cover 3 from the chip inlet 7.

[0068] The transverse drive mechanism 15 is connected to the moving frame 11 and to the transverse seat 12, and is used to drive the transverse seat 12 to move left and right, thereby driving the saw blade 2 on the cutting motor 1 to move left and right.

[0069] The reset drive component 16 is connected to the base frame 10 and the movable frame 11, and is used to drive the movable frame 11 to move backward and reset when the clamping mechanism 17 releases the product on the cutting platform 18 and the upper end of the saw blade 2 exits downward from the cutting groove 19.

[0070] Both the water receiving tank 5 and the water supply tank 4 are connected to the movable frame 11, with the water receiving tank 5 located below the protective cover 3.

[0071] Specifically, the product passes over the cutting platform 18 and is supported by it. When the product moves forward a distance that reaches the designed distance, the clamping mechanism 17 presses the moving product onto the cutting platform 18. At this time, the cutting platform 18, along with the entire moving frame 11, moves forward synchronously with the product. Consequently, the transverse seat 12, the lifting seat 13, the saw blade 2 on the cutting motor 1, the protective cover 3, and the water receiving tank 5 all move forward synchronously with the moving frame 11. Then, the cutting motor 1 drives the saw blade 2 to rotate at high speed. The lifting drive mechanism 14 drives the lifting seat 13 to rise, thereby lifting the saw blade 2 on the cutting motor 1, so that the upper end of the saw blade 2 extends from the chip inlet 7 to outside the protective cover 3 and passes upward through the cutting groove 19. Then, the transverse drive mechanism 15 drives the transverse seat 12 to move left and right, thereby moving the saw blade 2 on the cutting motor 1 left and right, thus enabling the high-speed rotating saw blade 2 to cut the product. After cutting, the lifting drive mechanism 14 drives the lifting seat 13 to descend, which in turn drives the saw blade 2 on the cutting motor 1 to descend, so that the upper end of the saw blade 2 exits the cutting groove 19 and retracts into the protective cover 3 from the chip inlet 7. Then, the lateral drive mechanism 15 drives the lateral seat 12 to move back to the starting position in the left and right direction. Then, the clamping mechanism 17 releases the product on the cutting platform 18, and then the reset drive component 16 drives the moving frame 11 to move backward to reset in preparation for the next cut. Specifically, the chips generated from cutting the product pass through the cutting groove 19 and fall into the protective cover 3 from the chip inlet 7. Then, the chips are discharged from the outlet 8 at the lower end of the protective cover 3 along with the cooling water and are collected by the water tank 5. In this embodiment, the cutting motor 1 is connected to the lifting base 13, and the protective cover 3 is connected to the transverse base 12. Therefore, when the transverse base 12 moves in the left-right direction, the saw blade 2 on the cutting motor 1 and the protective cover 3 will move together in the left-right direction. When the lifting base 13 moves up and down, only the saw blade 2 on the cutting motor 1 will move up and down, while the protective cover 3 will not move up or down. The cutting platform 18 is part of the moving frame 11, and the protective cover 3 is provided with a transparent viewing window 20.

[0088] The clamping seat 30 is connected to the clamping cylinder 31 and located above the cutting platform 18.

[0089] The clamping seat 30 is provided with a receiving groove 32 with the opening facing downward for the upper end of the saw blade 2 to extend into.

The adjustment mechanism may include at least two adjustment components, including a first screw jack 37, a second screw jack 38, a first pad 39, a second pad 40, a drive shaft 41, and an adjustment motor 42.
