Description

Technical Field

[0001] This utility model relates to the technical field of embossing equipment for galvanized steel sheets, and in particular to an adjustable roller for embossing galvanized steel sheets. Background Technology

[0002] Galvanized steel sheet refers to steel sheet with a layer of zinc coating on its surface. Galvanizing is a commonly used, economical, and effective method of rust prevention, and about half of the world's zinc production is used for this process.

[0003] An adjustable galvanized sheet flattening embossing roller, such as the one disclosed in CN219583839U, includes an operating table. A clamping and moving mechanism is provided on the outer surface of the operating table, and an adjustment mechanism is provided at the upper end of the operating table. The beneficial effects of this invention are as follows: A galvanized sheet is placed on the upper end of a placement platform. Then, a first telescopic rod extends and retracts, pushing the clamping plates along the groove until the two sets of pushing clamping plates clamp the galvanized sheet. Due to the presence of soft clamping blocks, the galvanized sheet is not damaged. Next, a second telescopic rod extends and retracts, pushing the horizontal plate and connecting rod to move, thereby moving the placement platform along the groove. When it is necessary to press the embossing roller down, a third telescopic rod extends and retracts, pushing the U-shaped plate along the round rod. At this time, the pressure roller moves accordingly, and the rotating shaft rotates, thereby driving the pressure roller to rotate. With the placement platform moving back and forth, the pressure roller can emboss the galvanized sheet.

[0004] The above technical solution has some problems in actual use. Although the technical solution can adjust the pressure roller to adapt to galvanized sheets of different thicknesses, it can only drive a single pressure roller in the process of adjusting the position of the pressure roller. A single pressure roller can only perform single-sided embossing on the galvanized sheet, which is inefficient.

[0005] Therefore, it is necessary to invent an adjustable roller for embossing galvanized steel sheets to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable roller for embossing galvanized steel sheets, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable roller for embossing galvanized steel sheets, comprising a frame, with grooves formed in the middle of both sides of the frame, a slide seat provided inside the groove, a movable roller movably mounted on the inner side of the slide seat via bearings, and a fixed roller movably mounted on the bottom inner side of the frame via bearings. Both the fixed roller and the movable roller are embossing rollers. An adjusting screw is rotatably threaded through the top of the inner wall of the groove, a threaded sleeve is fixedly mounted on the top of the slide seat, and the bottom of the adjusting screw is inserted into the threaded sleeve. A transmission rod is provided at the top of the frame, with both ends of the transmission rod being connected to the top of the adjusting screw via bevel gear sets. Supports are movably mounted on both ends of the transmission rod via bearings, and the supports are fixedly mounted on the top of the frame.

[0008] Preferably, a drive motor is fixedly installed at the bottom of the outer side wall of the frame, and the output shaft of the drive motor is connected to one end of the fixed roller.

[0009] Preferably, a drive sprocket is movably mounted on the outer bottom end of the frame via a bearing, and a transmission gear is mounted on the inner side of the drive sprocket and one end of the fixed roller, with the two transmission gears meshing with each other.

[0010] Preferably, a driven sprocket is fixedly provided at one end of the movable roller, and a transmission chain is provided between the driven sprocket and the drive sprocket.

[0011] Preferably, a tension sprocket is provided on the inner side of the transmission chain, and a movable seat is movably provided on the inner side of the tension sprocket via a bearing. A slide rod is fixedly provided at the top of the movable seat, and a positioning sleeve is sleeved on the middle of the slide rod. The positioning sleeve is fixedly provided on the outer side of the frame, and a spring is provided between the top of the slide rod and the positioning sleeve.

[0012] Preferably, a support frame is fixedly installed on the outer side of the frame, and two clamping plates are installed on the inner side of the support frame. A positioning screw sleeve is fixedly installed at the bottom center of the clamping plate. A double-ended screw is inserted through the inside of the positioning screw sleeve, and the double-ended screw is movably installed inside the support frame through a bearing. A limit sleeve is fixedly installed at the bottom of the clamping plate, and a limit rod is inserted through the inside of the limit sleeve, and the limit rod is fixedly installed inside the support frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model sets up a movable roller and a fixed roller inside the frame. One end of the fixed roller is equipped with a drive motor, and the other end of the fixed roller is equipped with a drive sprocket through a transmission gear. The drive sprocket can drive a driven sprocket through a transmission chain, and the driven sprocket can drive the movable roller to rotate, so as to achieve synchronous rotation of the movable roller and the fixed roller. Furthermore, a tension sprocket is set on the inner side of the transmission chain to ensure the tension of the transmission chain, thereby ensuring the transmission effect during the position adjustment process between the movable roller and the fixed roller. This allows the device to adjust according to the thickness of the galvanized sheet while ensuring synchronous rotation of the movable roller and the fixed roller, so as to achieve the effect of double-sided processing of the galvanized sheet.

[0015] 2. This utility model provides a support frame on one side of the machine frame, with two clamping plates on the inner side of the support frame. The two clamping plates can guide the position of the galvanized sheet to prevent it from shifting during the embossing process. Furthermore, the position of the clamping plates can be adjusted by positioning screw sleeves and double-ended screws to accommodate various specifications of galvanized sheets. This ensures the processing accuracy of the galvanized sheet while expanding the adaptability of the device. Attached Figure Description

The drive sprocket 12 drives the driven sprocket 14 to rotate through the transmission chain 15. The driven sprocket 14 drives the movable roller 4 to rotate. The movable roller 4 cooperates with the fixed roller 5 to realize double-sided embossing processing of the galvanized sheet. In this process, by rotating the handwheel in the middle of the transmission rod 8, the transmission rod 8 drives the two adjusting screws 7 to rotate through the bevel gear set 9. The adjusting screws 7 cooperate with the threaded sleeve 6 to make the two slides 3 slide up and down. The slides 3 can drive the movable roller 4 to move, so as to realize the adjustment of the position between the movable roller 4 and the fixed roller 5.

[0027] When processing galvanized sheets of different widths, the handwheel in the middle of the double-ended screw 23 is rotated to make it rotate. The double-ended screw 23 cooperates with the positioning screw sleeve 22, causing the two clamping plates 21 to move relative to each other, so that the distance between the two clamping plates 21 is adjusted, thereby ensuring the guiding effect of the clamping plates 21 on galvanized sheets of different widths.
