Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to a traction machine that is easy to adapt to the adjustment of sheet thickness. Background Technology

[0002] A Chinese utility model patent with publication number CN217434985U, entitled "An Adjustable Gap Hollow Board Traction Machine," discloses that the threaded ends of the telescopic rods of each pressure roller cylinder, away from the T-shaped support, are equipped with adjusting nuts and locking nuts. By locking the locking nuts, the gap between the pressure roller and the traction roller is precisely adjusted, ensuring the hollow board thickness meets requirements. However, operation requires turning each adjusting nut and locking nut, which is cumbersome, inefficient, and makes it difficult to ensure consistent vertical displacement of each adjusting nut, resulting in poor adjustment accuracy and potentially causing inconsistent gaps between the pressure roller and the traction roller, thus affecting the traction effect. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a traction machine that is easy to operate, can improve work efficiency, can improve adjustment accuracy, can ensure that the gap height between the pressure roller and the traction roller is consistent, thereby ensuring the traction effect and is easy to adapt to the adjustment of the plate thickness.

[0004] To achieve the above objectives, the technical solution adopted by the traction machine of this utility model, which is easy to adapt to the adjustment of plate thickness, is as follows:

[0005] A traction machine for easy adjustment of sheet material thickness includes a frame with several traction rollers pivotally connected to it. Above each traction roller is a pressure roller, and both ends of the pressure rollers are pivotally connected to lifting sliders, which are slidably connected to the frame. The frame is equipped with a gap adjustment device, which includes a synchronous drive mechanism fixed to the frame. The synchronous drive mechanism is connected to linkage rods located on both sides of the pressure rollers. Several gap adjustment blocks are sleeved on the outer sides of the linkage rods, and each gap adjustment block has a slope for supporting the pressure rollers. When the synchronous drive mechanism simultaneously drives the linkage rods on both sides to move horizontally, the pressure rollers move vertically on the slopes on both sides, thereby quickly adjusting the gap between them and the traction rollers to meet the production needs of sheets of different thicknesses.

[0006] Preferably, the synchronous drive mechanism includes a second linkage rod, with a screw jack connected to both ends of the second linkage rod, and the screw of the screw jack connected to the first linkage rod.

[0007] Preferably, the linkage rod is a threaded rod, and the threaded rod is threadedly connected to a limiting nut for preventing the gap adjusting block from shifting.

[0008] Preferably, the frame is provided with guide blocks that correspond one-to-one with the gap adjustment blocks, and the guide blocks have sliding grooves for the gap adjustment blocks to slide. Although there are pressure rollers pressing on the slope of the gap adjustment blocks, guide blocks are added to ensure that the gap adjustment blocks do not rotate.

[0009] Preferably, the bottom surface of the groove is provided with a plurality of lubricating rolling elements, and the guide block is provided with limiting baffles on both sides to prevent the lubricating rolling elements from slipping off. The lubricating rolling elements reduce the friction between the gap adjusting block and the guide block, facilitating the sliding of the gap adjusting block.

[0010] Preferably, rolling bearings that abut against the slope are provided on both sides of the pressure roller. The rolling bearings reduce the friction between the gap adjusting block and the pressure roller, facilitating the vertical movement of the pressure roller.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] The synchronous drive mechanism drives the linkage rods on both sides to move horizontally, thereby driving all the pressure rollers to move vertically on the corresponding slope. No individual adjustment is required, making operation more convenient and improving work efficiency. At the same time, the vertical displacement at both ends of the same pressure roller and between adjacent pressure rollers can also be kept consistent, thereby improving adjustment accuracy and ensuring traction effect.

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0020] like Figure 1-5 As shown, a traction machine that is easy to adapt to the thickness adjustment of sheet metal includes a frame 1. The frame is pivotally connected to three horizontally arranged traction rollers 2. Pressure rollers 3 are installed above the traction rollers, one for each roller. The pressure rollers are directly above the traction rollers and parallel to them. Lifting sliders 31 are pivotally connected to the left and right ends of the pressure rollers. The lifting sliders are slidably connected to the frame via lifting guide rails 11. The frame is equipped with a gap adjustment device 4. The gap adjustment device includes a synchronous drive mechanism 41 fixed to the frame. The synchronous drive mechanism includes a second linkage rod 411. The two ends of the second linkage rod are connected to a screw jack 412. The screw of the screw jack is connected to a first linkage rod 42. The first linkage rod is located on both sides of the pressure roller. The first linkage rod is a threaded rod. Three gap adjustment blocks 43 are sleeved on the outside of the threaded rod. Limit nuts 421 are installed on both sides of the gap adjustment blocks. The limit nuts are threadedly connected to the threaded rod to prevent the gap adjustment blocks from moving in the threaded position. When displacement occurs on the rod, the gap adjusting block has a slope 431 for supporting the pressure roller. Three guide blocks 5 are installed on each side of the frame, and the guide blocks correspond one-to-one with the gap adjusting blocks. The guide blocks have a sliding groove 51 for the gap adjusting blocks to slide. The guide blocks prevent the gap adjusting blocks from rotating and also provide stable support for the pressure roller. Several lubricating rolling elements 52 are installed on the bottom surface of the sliding groove. Limiting baffles 53 are installed on both sides of the bottom of the guide blocks to prevent the lubricating rolling elements from slipping. The lubricating rolling elements reduce the friction between the gap adjusting block and the guide block, making it easier for the gap adjusting block to slide. Rolling bearings 32 that abut against the slope are installed on both sides of the pressure roller. The rolling bearings reduce the friction between the gap adjusting block and the pressure roller, making it easier for the pressure roller to move vertically. Because the gap adjusting block has a lubricating rolling element at the bottom and the pressure roller also has rolling bearings that abut against the slope on both sides, it is not difficult to turn the handwheel, making it easy to operate.

[0021] The specific working process and principle of this utility model are as follows: When it is necessary to reduce the gap between the pressure roller and the traction roller, turn the handwheel on either side of the screw jack clockwise. The worm of the screw jack on that side drives the worm of the screw jack on the other side to rotate synchronously through the linkage rod two. The screws of both screw jacks extend simultaneously, pushing the threaded rod. The threaded rod drives each gap adjustment block to move away from the screw jack. The pressure roller moves downward along the lifting guide rail under its own gravity. When it is necessary to increase the gap between the pressure roller and the traction roller, turn the handwheel on either side of the screw jack counterclockwise. The worm of the screw jack on that side drives the worm of the screw jack on the other side to rotate synchronously through the linkage rod two. The screws of both screw jacks retract simultaneously, pulling the threaded rod. The threaded rod drives each gap adjustment block to move closer to the screw jack. The slope forces the pressure roller to move upward along the lifting guide rail. This invention uses two linked screw jacks to synchronously drive the screw rods on both sides. The screw rods drive the gap adjustment blocks to move horizontally, while simultaneously driving the pressure rollers to move vertically on the corresponding slope. This allows for one-time adjustment of the gap between each pressure roller and its corresponding traction roller. The operation is convenient, the work efficiency is high, and the precision is high, ensuring the traction effect of the traction machine.
