For example, although the bearings in the front bearing box in the specification are described in combination with four, the present application can obviously adopt other numbers of bearings, for example, the number of bearings can also be two, three, five, six, etc.
[0035] It should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "set", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or other connections; it can be directly connected or indirectly connected through an intermediate medium.

It should be understood that the orientation or positional relationship indicated by the terms "outside", "inside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, "multiple" in this application means at least two.
[0036] like Figure 1-4 As shown, in order to solve the problem that the unevenly distributed mass of the existing main roller will cause vibration when it rotates at high speed, and the vibration will cause equipment damage and performance degradation, the utility model provides a main roller device, including a main roller 1, two bearing boxes, a tie rod 5, a pressure block 4 and a counterweight block 6. The main roller 1 is fixed between the two bearing boxes by the tie rod 5, the pressure block 4 is sleeved on the tie rod 5 and crimped with one of the bearing boxes; the counterweight block 6 is connected to the pressure block 4, and the counterweight block 6 is used to balance the mass of the main roller device.
[0037] In this way, the mass distribution of the main roller device is uneven, and vibration will occur when it rotates. By connecting the counterweight block 6 to the pressure block 4, the mass distribution on the main roller device is changed, and the mass of the main roller device is balanced, so that the overall mass distribution is more uniform, reducing the vibration caused by the unevenly distributed mass, and avoiding equipment damage and performance degradation caused by vibration. Compared with dynamic balancing of the main roller 1 alone, dynamic balancing of the main roller device can reduce the vibration caused by the uneven mass distribution of other components connected to the main roller 1.
[0038] See attached Figure 1 and 3 In a preferred embodiment, the main roller device includes a main roller 1, a bearing box, a pull rod 5, a pressure block 4 and a counterweight block 6.
[0039] There are two bearing boxes, namely the front bearing box 22 and the rear bearing box 21. The front bearing box 22 includes a box body 221, a bearing 223, a flange 222 and a rotating shaft 224; a cavity capable of accommodating the bearing 223 is provided in the box body 221, and the number of the bearings 223 is four, and the four bearings 223 are provided in the box body 221, and the rotating shaft 224 is plugged into the bearing 223, and a through hole for the pull rod 5 to pass through is also provided in the rotating shaft 224. The flange 222 is connected to the box body 221, and the flange 222 is used to prevent the bearing 223 from escaping from the cavity. Here is only a brief description of the structure of the front bearing box 22, and the specific structure of the bearing box is the prior art, which will not be repeated here.
[0040] There is no through hole in the rotating shaft 224 of the rear bearing box 21. One end of the rear bearing box 21 for pressing the main roller 1 is provided with a threaded hole, which is used to connect with the tie rod 5. The other structures of the rear bearing box 21 are the same as those of the front bearing box 22, and will not be repeated here.
[0041] It should be noted that the configuration of the front bearing box 22 and the rear bearing box 21 is not mandatory, and those skilled in the art can select the specific configuration of the front bearing box 22 and the rear bearing box 21 based on the specific application scenario. For example, the number of the bearings 223 can also be two, three, five, six, etc. For another example, the rear bearing box 21 is not provided with a threaded hole, and a clamp is used to fix one end of the pull rod 5.
[0042] The main roller 1 is fixed between the two bearing boxes by a tie rod 5, one end of the tie rod 5 is connected to the rotating shaft of the rear bearing box 21, and the other end of the tie rod 5 passes through the through hole in the rotating shaft 224 of the front bearing box 22, and is provided with a threaded groove, on which a fastening nut 7 is threadedly connected, and a pressure block 4 is arranged between the fastening nut 7 and the front bearing box 22. When the fastening nut 7 is tightened, the front bearing box 22 can be pressed by the pressure block 4, so that the position of the front bearing box 22 can be moved, thereby achieving the fixation of the main roller 1.
[0043] It should be noted that the provision of the fastening nut 7 is not mandatory. Technical personnel in this field can choose whether to provide the fastening nut 7 and the specific structure of the fastening nut 7 based on the specific application scenario. Of course, other methods can also be used to tighten the pressure block 4. For example, a cylinder is provided on the pull rod 5 and is sleeved on the pull rod 5. A protrusion for the cylinder to tighten is provided on the pull rod 5. One end of the cylinder presses the protrusion, and the other end of the cylinder presses the pressure block 4. The front bearing box 22 can be pressed by the pressure block 4, so that the position of the front bearing box 22 can be moved, thereby achieving the fixation of the main roller 1.
[0044] See attached Figure 4 , a plurality of fixing holes 41 are provided on the side of the pressing block 4 away from the front bearing box 22, and the plurality of fixing holes 41 are all provided on the side of the pressing block 4 away from the front bearing box 22. The counterweight block 6 is an arc-shaped block and a circular block that fits the end surface of the pressing block 4 at different positions. A through hole is provided on the counterweight block 6, and a bolt passes through the through hole and is connected to one of the fixing holes 41, thereby connecting the counterweight block 6 to the pressing block 4. The plurality of fixing holes 41 are evenly spaced around the axis of the pressing block 4, so that when the counterweight block 6 is fixed, it can be fixed at any position around the axis of the pressing block 4. At the same time, the counterweight block 6 can be more conveniently fixed to the pressing block 4 by bolts.
[0045] It should be noted that the arrangement of the above structure is not necessary, and those skilled in the art can select the specific structure of the above structure based on the specific application scenario. For example, the number of fixing holes 41 can be one, the counterweight block 6 is a ring with uneven mass, a plurality of through holes are arranged on the counterweight block 6, the counterweight block 6 is sleeved on the pull rod 5, and is connected to the fixing hole 41 through different through holes to achieve the balance of the overall mass. Of course, the number of fixing holes 41 can also be two, three, four or five. For another example, the fixing holes 41 are randomly distributed around the axis of the pressing block 4. For another example, no through hole is arranged on the counterweight block 6, a slot capable of clamping the counterweight block 6 is arranged on the pressing block 4, and a bolt capable of fixing the counterweight block 6 is arranged on the slot, the counterweight block 6 can be placed in the slot, and fixed in the slot by bolts. For another example, the counterweight block 6 is bonded to the pressing block 4. For another example, the counterweight block 6 is not connected by bolts, but is connected to the fixing hole 41 by a fixing pin passing through the through hole, so that the counterweight block 6 is connected to the pressing block 4.
[0046] It should be further explained that the counterweight block 6 in the figure is only for clearly showing the connection relationship, and the size and shape of the counterweight block 6 are not unique, and it can be connected to the pressing block 4. For example, the counterweight block 6 can be a sheet with a through hole, or it can be an irregular shape.
[0047] See attached Figure 1-4The utility model also provides a wire cutting machine, including the above-mentioned main roller device. In this way, the mass distribution of the main roller device is uneven, and vibration will be generated when it rotates. By connecting the counterweight block 6 to the pressure block 4, the mass distribution on the main roller device is changed, and the mass of the main roller device is balanced, so that the overall mass distribution is more uniform, reducing the vibration caused by the unevenly distributed mass, and avoiding equipment damage and performance degradation caused by vibration. Compared with dynamic balancing of the main roller 1 alone, dynamic balancing of the main roller device can reduce the vibration caused by the uneven mass distribution of other components connected to the main roller 1.
[0048] The wire cutting machine is preferably a slicer. Of course, it can also be other wire cutting machines that adopt the above-mentioned device, such as mortar machines etc.
[0049] See attached Figure 1-4 The utility model also provides a dynamic balancing adjustment system, comprising: a vibration detection component; the above-mentioned main roller device or the above-mentioned wire cutting machine; the vibration detection component is configured to detect the vibration frequency of the main roller device.
[0050] In the case of adopting the above technical solution, the overall vibration condition can be detected by the vibration detection component, and the fixed position of the counterweight block 6 can be easily determined according to the vibration condition detected by the vibration detection component. In this way, the overall vibration condition of the main roller device can be detected by the vibration detection component, and the counterweight block 6 is connected to the pressure block 4 to change the mass distribution method on the main roller device, balance the mass of the main roller device, make the overall mass distribution more uniform, reduce the vibration caused by the unevenly distributed mass, and avoid equipment damage and performance degradation caused by vibration. Compared with dynamic balancing of the main roller 1 alone, dynamic balancing of the main roller device can reduce the vibration caused by the uneven mass distribution of other components connected to the main roller 1.
[0051] See attached Figure 1 In a preferred embodiment, the vibration detection component includes a vibration sensor 3, and the vibration sensor 3 is connected to the outer side of the flange 222 of the front bearing box 22. In this way, the vibration of the main roller device as a whole can be detected by the vibration sensor 3, and the fixed position of the counterweight 6 can be determined according to the vibration detected by the vibration sensor 3.
[0052] It should be noted that the vibration sensor 3 is an electronic device used to measure or detect the vibration of an object. It can detect information such as the vibration amplitude, frequency, and direction of an object in space and convert it into a readable signal, such as a change in voltage or current, for subsequent analysis and processing. The specific structure and detection method of the vibration sensor 3 are prior art and will not be elaborated here. Of course, the vibration sensor 3 is preferred, and those skilled in the art can select the specific structure of the vibration detection component based on the specific application scenario. For example, an acceleration sensor can be selected to detect vibration by measuring the acceleration changes of the object in three axial directions. Another example is a fiber optic sensor that detects vibration by utilizing the principle that the refractive index of an optical fiber changes with vibration.
[0053] It should also be noted that the setting of the vibration sensor 3 is not necessary, and those skilled in the art can select the installation position of the vibration sensor 3 based on the specific application scenario. For example, the vibration sensor 3 is connected to the housing 221 of the front bearing housing 22.
[0054] See the appendix Figure 2 and 4 , in a preferred embodiment, the dynamic balance adjustment system further includes a sensor bracket 8 and a speed sensor 9. The sensor bracket 8 is in a "C" shape and is arranged on the housing 221. The speed sensor 9 is fixedly connected to the sensor bracket 8. The speed sensor 9 is used to detect the rotational speed of the main roller 1. In this way, by detecting the rotational speed of the main roller 1 through the speed sensor 9, it is possible to determine whether the main roller 1 has reached the operating speed, and after reaching the operating speed, the detection of vibration is started.
[0055] A reflective strip is provided on the outer side surface of the pressing block 4. The speed sensor 9 uses a photoelectric sensor, and the photoelectric sensor uses photosensitive elements (such as photodiodes or photoresistors). When the external light source irradiates the reflective strip, when the pressing block 4 rotates, the number of times of the reflected light of the reflective strip detected by the photoelectric sensor is used to determine the rotational speed of the pressing block 4.
[0056] It should be noted that the setting of the sensor bracket 8 and the speed sensor 9 is not necessary, and those skilled in the art can select whether to set the sensor bracket 8 and the speed sensor 9 and the specific structure of the sensor bracket 8 and the speed sensor 9 based on the specific application scenario. For example, the sensor bracket 8 is in an "L" shape. Another example is not to set the sensor bracket 8 and connect the speed sensor 9 to the housing 221 of the front bearing housing 22. Another example is that the speed sensor 9 can select a Hall effect sensor, and a magnet is provided on the outer side surface of the pressing block 4. When the pressing block 4 rotates, the sensor senses the change in the magnetic field, thereby detecting the rotational speed of the pressing block 4. Another example is not to set the speed sensor 9 and the sensor bracket 8, and the rotational speed of the main roller is obtained through the slicing machine system.
[0057] Combined with the appendix Figure 1-4, a possible method for realizing dynamic balance adjustment of the main roller device of the utility model is introduced below.
[0058] In one possible implementation, the device is started to rotate the main roller 1, and the speed sensor 9 detects the rotation speed of the main roller 1. When the rotation speed of the main roller 1 reaches the working speed, the vibration sensor 3 detects the frequency and amplitude of the vibration of the main roller device, and the magnitude and phase of the imbalance of the main roller device are determined according to the frequency and amplitude of the vibration, and the counterweight block 6 is fixed to the pressure block 4 at the corresponding position by bolts. The device is started again, and the vibration frequency and amplitude are detected at the working speed. If the vibration condition is significantly improved, it means that the debugging is successful. If the improvement is not obvious, the position and size of the counterweight block 6 are adjusted again, and debugging is performed multiple times until the vibration condition is significantly improved.

For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.
[0060] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
