Description

Technical Field

[0001] The utility model relates to the technical field of clothing production and processing, in particular to a pressure roller lifting device of a hot and cold belt cutting machine. Background Art

[0002] Hot and cold tape cutting machine is a kind of tape cutting equipment in clothing production and processing. It is used to cut the processed cloth tape into the required length so that it can be applied to clothing.

[0003] The tape cutting machine includes an operating table, a cutting mechanism, a conveying mechanism and a guide mechanism. The conveying mechanism includes a motor, a driving roller and a pressure roller. The motor is fixedly connected to the operating table, and the driving roller and the pressure roller are rotatably connected to the operating table. The pressure roller is located above the driving roller. The motor drives the driving roller to rotate through a synchronous belt and synchronous wheel. The pressure roller and the driving roller are connected by a gear transmission. During transportation, the cloth tape passes between the two rollers, the motor belt drives the driving roller to rotate, and the driving roller drives the pressure roller to rotate, thereby conveying the cloth tape.

[0004] To pass the fabric strip between the drive roller and the pressure roller, the pressure roller must be moved away from the drive roller to create a gap between them so that the fabric strip can pass between the two rollers. This is typically accomplished by installing two vertically sliding sliders on the operating table through a connecting frame. The pressure roller's ends are rotatably connected to the two sliders, respectively. A connecting plate, located above the sliders, is threaded with vertical bolts. The bolts' ends are rotatably connected to the sliders. Turning the two bolts drives the pressure roller, which is connected to the sliders, up and down. While turning the bolts is cumbersome, it allows for adjusting the pressure of the pressure roller on the fabric bag, preventing insufficient force between the fabric strip and the pressure roller, which could cause slippage and affect conveying. Alternatively, a rotating arm is rotatably connected to the connecting frame. A tension spring is connected between the rotating arm and the connecting frame. Rotating the rotating arm drives the pressure roller away from the drive roller. After the fabric strip passes between the two rollers, the tension spring pulls the rotating arm, causing the rotating arm to drive the pressure roller to compress the fabric strip. This is convenient, but the pressure of the pressure roller on the fabric strip cannot be adjusted. Both methods are not very practical. Utility Model Content

[0005] The purpose of the utility model is to provide a pressure roller lifting device for a hot and cold strip cutting machine, so as to solve the above problems.

[0008] Similarly, by turning bolt one upwards, the pressure block rises, the force of the spring on the slider is reduced, and the force of the pressure roller on the cloth belt is reduced, thereby preventing the force between the cloth belt and the two rollers from being too large and affecting the rotation of the roller.

[0009] Preferably, a motor is fixedly connected to the bottom side of the console, the motor output shaft is connected to the driving roller via a synchronous wheel and synchronous belt transmission, and the driving roller and the pressure roller are connected via a transmission member.

[0010] By adopting the above technical solution, the motor drives the driving roller to rotate through the synchronous belt and synchronous wheel.

[0011] Preferably, the transmission member is a gear, and the ends of the pressure roller and the driving roller are respectively fixedly connected with gears, and the gears of the two are meshed with each other.

[0012] With the above technical solution, the rotating driving roller drives the pressing roller to rotate through the gear meshing between the driving roller and the pressing roller, and the driving roller and the pressing roller drive the cloth belt therebetween to move.

[0013] Preferably, it also includes a guide mechanism, which includes a guide rod, a limit plate and two bolts. The guide rod is located above the operating table, close to the support, and both ends of the guide rod are fixedly connected with connecting blocks, the connecting blocks are fixedly connected to the operating table, and there is a distance between the guide rod and the operating table.

The second bolt vertically passes through the upper part of the limit plate, and the second bolt is threadedly connected to the limit plate. The two ends of the bolt contact the guide rod.

[0014] Using the above technical solution, the cloth belt is placed under the guide rod, and the cloth belt is passed between two adjacent limit plates. Then the limit plates on both sides of the cloth belt are moved so that the limit plates contact the edges of the cloth belt. Then, bolt two is tightened so that bolt two presses against the guide rod to fix the limit plates. The limit plates block both sides of the cloth belt to prevent left and right deviation during conveyance, which affects cutting.

[0015] Preferably, a triangular block is integrally formed on the end of the shift block that contacts the slider, and the top of the triangular block contacts the bottom of the slider.

[0016] By adopting the above technical solution, the contact area between the shifting block and the bottom of the slider is reduced, so that the shifting block can better shift the slider to move it upward.

[0017] Preferably, an upper end of the bolt is fixedly connected with a rotary handle.

One end of the driving roller 4 is fixedly connected to a driven synchronous wheel, and a synchronous belt is connected between the two synchronous wheels. A connecting frame 2 is fixedly connected to the upper surface of the control console 1. Vertical slide grooves are respectively provided on the two side walls of the connecting frame 2. Each slide groove is respectively embedded with a slider 5. The slider 5 is slidably connected to the side wall of the connecting frame 2. The pressure roller 3 is located between the two arms of the connecting frame 2 and above the driving roller 4. The two ends of the pressure roller 3 are respectively rotatably connected to the two sliders 5. The gears 13 of the driving roller 4 and the pressure roller 3 are meshed with each other. Vertical bolts 6 are threadedly connected to both sides of the top of the connecting frame 2. The upper end of the bolt 6 is fixedly connected to a rotary handle, and the lower end of the bolt 6 is rotatably connected to a pressure block 7. A spring 8 is fixedly connected between the pressure block 7 and the slider 5.

[0028] See Figure 4-Figure 6 , also includes a rotating shaft 9, which passes horizontally through the two side walls of the connecting frame 2, and is rotatably connected to the side walls. A handle 10 is fixedly connected to one end of the rotating shaft 9, and a shift block 11 is fixedly connected to each end of the rotating shaft 9. The shift block 11 is located on the outside of the side wall of the connecting frame 2, and the shift block 11 contacts the bottom of the slider 5. The shift block 11 is L-shaped, and one end of the shift block 11 is fixedly connected to the rotating shaft 9, and the other end is integrally formed with a triangular block 18, and the top of the triangular block 18 contacts the bottom of the slider 5. Connecting blocks 14 are fixedly connected to both sides of the upper surface of the operating table by bolts, and also include a guide rod 15 and a limit plate 16. The guide rod 15 passes through the two connecting blocks 14 and is fixedly connected to the connecting block 14. The guide rod 15 is close to the support, and there is a distance between the guide rod 15 and the operating table. There are multiple limiting plates 16, which are sleeved on the guide rod 15. The limiting plate 16 is slidably connected to the guide rod 15. The bottom of the limiting plate 16 contacts the operating table. Bolt 2 17 vertically passes through the top surface of the limiting plate 16 and is threadedly connected with a vertical bolt 2 17.

[0029] Working principle: Pass the cloth belt from under the guide rod 15, and then move the limit pieces 16 on both sides of the cloth belt to make the limit pieces 16 contact with the edge of the cloth belt, and then tighten the bolt 2 17 to make the bolt 2 17 press against the guide rod 15 to fix the limit pieces 16. The limit pieces 16 block both sides of the cloth belt to prevent left and right deviation when conveying the cloth belt, which affects the cutting. Turn the handle 10 to rotate the shaft 9 and the shifting blocks 11 at both ends of the shaft 9. The shifting blocks 11 exert force on the slider 5 to make the slider 5 rise. The slider 5 compresses the spring 8. At the same time, the slider 5 drives the pressure roller 3 to rise, and the pressure roller 3 moves away from the driving roller 4. Then, pass the cloth belt between the pressure roller 3 and the driving roller 4, and rotate the handle in the opposite direction. By moving the handle 10, the shift block 11 is separated from the slider 5, and the spring 8 rebounds to push the slider 5 down and press the cloth belt, which is convenient to operate, saves time and improves work efficiency. At the same time, the bolt 6 can be turned to push the pressure block 7 down, compressing the spring 8. The elasticity of the spring 8 increases, and the force on the slider 5 increases, thereby increasing the force of the pressure roller 3 on the cloth belt, preventing the cloth belt from slipping between the pressure roller 3 and the driving roller 4, affecting the conveying. The motor 12 drives the driving roller 4 to rotate through the synchronous belt and synchronous wheel. The rotating driving roller 4 drives the pressure roller 3 to rotate through the gear 13 meshing between it and the pressure roller 3, and the driving roller 4 and the pressure roller 3 then drive the cloth belt between them to move.
