[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown;

[0023] An online paper tube straightness multi-point detection device comprises a chamfering machine 1.

[0024] In this embodiment: the main production process of paper tubes is striping, gluing, tube rolling, drying, precision cutting and packaging, wherein the paper tubes are glued to form hollow tubular objects by gluing. The gluing process causes the paper tubes to absorb a large amount of water, which needs to be dried through the drying process so that the paper tubes can have higher strength. During the drying process, the air volume and temperature of the drying room are uneven, and the moisture of the paper tubes is uneven during the drying process, resulting in bending of the paper tubes, which reduces the quality of the product. The existing detection method is through manual detection, which is time-consuming and labor-intensive, and has low work efficiency. In order to solve this technical problem, a detection component 2 is added on this basis.

[0025] More specifically:

[0026] like Figures 1 to 5 As shown:

[0027] In combination with the above content: the detection component 2 includes a mounting base 21, a sliding rod 22 and a sliding block 23. The mounting base 21 is fixedly connected to the outer side of the end of the chamfering machine 1, the sliding rod 22 is fixedly connected to the outer side of one end of the mounting base 21, and a plurality of sliding blocks 23 are slidably connected to the outer side of the end of the sliding rod 22. A first fixed column 24 and a second fixed column 25 are slidably connected to the inner side of one end of the sliding block 23. A threaded connecting rod 26 is fixedly connected to the outer side of the end of the first fixed column 24, and a first nut 27 is threadedly connected to the outer side of the end of the threaded connecting rod 26. The outer sides of one ends of the first fixed column 24 and the second fixed column 25 are in contact with the outer side of the end of the sliding rod 22, a straightness measuring instrument 28 is installed on the outer side of one end of the sliding block 23, a polyurethane roller 29 and a V-shaped rotating device 210 are installed on the upper surface of the end of the mounting base 21, and the V-shaped rotating device 210 passes through the polyurethane roller 29.

[0028] In this embodiment: during the operation of the device, the paper tube is first chamfered inside the chamfering machine 1. When the paper tube is chamfered from the chamfering machine 1, the chamfering machine 1 pushes the paper tube out, and the paper tube automatically rolls down to the upper surface of the polyurethane roller 29. At this time, the V-shaped rotating device 210 is lifted upward, and the paper tube is supported by the end of the V-shaped rotating device 210 until the paper tube is lifted off the polyurethane roller 29 to a suitable position. Then, the roller on the V-shaped rotating device 210 drives the paper tube to rotate. Three straightness measuring instruments 28 are located directly above the paper tube. When the V-shaped rotating device 210 drives the paper tube to rotate, the straightness measuring instrument 28 starts to detect the straightness of the paper tube. At the same time, the straightness measuring instrument 28 transmits real-time data to the PLC, reads the maximum and minimum values ​​in one circle, and then Then calculate the straightness of the paper tube. If the values ​​of the three groups are all within the qualified range, the paper tube is qualified. If one of the three groups of data is not within the qualified range, the paper tube is unqualified. After the detection is completed, the V-shaped rotating device 210 descends, and the paper tube falls onto the polyurethane roller 29. Then the roller of the polyurethane roller 29 rotates, and the qualified products and the unqualified products are respectively transmitted in two directions, that is, the qualified and unqualified paper tube products can be separated. The device can detect the single-point straightness of the paper tube online in real time. Compared with the traditional manual detection method, it greatly improves the detection speed and reduces the errors caused by human factors, thereby improving the detection accuracy. At the same time, the inner side of the end of the sliding block 23 is slidably connected with the first fixed column 24 and the second fixed column 25. The first fixed column 2 4 is fixedly connected with a threaded connecting rod 26 on the outer side of the end portion, and the second fixing column 25 is sleeved on the outer surface of the threaded connecting rod 26. An arc groove is provided on the outer side of one end of the first fixing column 24 and the second fixing column 25, and a circular through hole is provided on the inner side of one end of the sliding block 23. The inner wall surfaces of the arc grooves of the first fixing column 24 and the second fixing column 25 are in contact with the outer surface of the sliding rod 22, and the sliding rod 22 can limit the positions of the first fixing column 24 and the second fixing column 25. Because the second fixing column 25 is only slidably connected with the non-threaded part of the threaded connecting rod 26 and conflicts with the threaded part of the threaded connecting rod 26, the second fixing column 25 will not fall off the surface of the threaded connecting rod 26, and the sliding rod 22 limits the position of the first fixing column 24, and the first fixing column 24 is also not The first nut 27 is rotated to increase the gap between the first fixing column 24 and the second fixing column 25, thereby reducing the pressure of the arc grooves at the ends of the first fixing column 24 and the second fixing column 25 on the sliding rod 22, so that the sliding block 23 can slide on the surface of the sliding rod 22. When the position is suitable, the first nut 27 is rotated in the opposite direction to bring the first fixing column 24 and the second fixing column 25 closer to each other, thereby reducing the distance between the arc grooves of the first fixing column 24 and the second fixing column 25, increasing the pressure of the first fixing column 24 and the second fixing column 25 on the sliding rod 22, and making the inner wall surface of the arc grooves of the first fixing column 24 and the second fixing column 25 press against the outer surface of the sliding rod 22.That is, the fixing of the sliding block 23 is completed. Through the sliding block 23, the first fixing column 24 and the second fixing column 25, the user can adjust the position of the straightness measuring instrument 28 on the sliding rod 22 as required, which increases the flexibility and practicality of the device. At the same time, when the user unscrews the first nut 27 from the outer surface of the threaded connecting rod 26, the straightness measuring instrument 28 will not fall off, further increasing the safety of the device.

[0031] In the present embodiment: a servo slide rail 211 is installed on the outer side of the end of the mounting base 21, and the V-shaped rotating device 210 passes through the slide groove opened in the mounting base 21 and is connected to the servo slide rail 211. When the position of the V-shaped rotating device 210 needs to be adjusted, it is only necessary to start the servo slide rail 211 and adjust it to the corresponding distance according to the different sizes and models of paper tubes. The adjustment of the position of the V-shaped rotating device 210 is completed. The user can adjust the position of the V-shaped rotating device 210 according to the different models of paper tubes, which further increases the flexibility of the device.

[0032] It should be noted that the V-shaped rotating device 210 can be extended and retracted to a certain extent, and the height of the V-shaped rotating device 210 can be adjusted with one key according to the size specifications of the paper tube.

[0033] Going further:

[0034] In an optional embodiment, a baffle 213 is fixedly connected to the outer side of one end of the mounting base 21 , and the baffle 213 is an arc-shaped structure.

[0035] In this embodiment: a baffle 213 is fixedly connected to the outer side of one end of the polyurethane roller 29. The baffle 213 is an arc-shaped structure. The paper tube will roll to the top of the polyurethane roller 29. For paper tubes that roll too far, the baffle 213 can block the paper tube to prevent it from falling. After the paper tube rises a certain distance on the surface of the baffle 213, it moves in the opposite direction under the action of gravity and returns to the surface of the polyurethane roller 29, thereby increasing the practicality of the device.

[0036] Going further:

[0037] In an optional embodiment, two side plates 214 are fixedly connected to the outer side of the end of the chamfering machine 1 .

[0038] In this embodiment: two side panels 214 are fixedly connected to the outer side of the end of the chamfering machine 1, and the side panels 214 are L-shaped structures. The side panels 214 can ensure that the paper tube will not fall from the end of the side panels 214. At the same time, the side panels 214 with the L-shaped structure can ensure the rolling stability of the paper tube. The side panels 214 with the L-shaped structure limit the position of the paper tube to a certain extent, so that the paper tube will not pop out from the end of the chamfering machine 1.

[0039] Going further:

[0040] In an optional embodiment, a pipe pushing device 212 and a conveyor belt 217 are installed on the outer sides of both ends of the mounting base 21, a packing platform 216 is installed on one side of the conveyor belt 217, and a limiting plate 215 is fixedly connected to the upper surface of the end of the packing platform 216.

[0041] In this embodiment: a tube pushing device 212 and a conveyor belt 217 are installed on the outer sides of both ends of the polyurethane roller 29, and a packaging platform 216 is installed on one side of the conveyor belt 217. When the paper tube is conveyed to the upper surface of the conveyor belt 217 by the polyurethane roller 29, the sensor on the conveyor belt 217 detects that the paper tube is in place, and then the tube pushing device 212 on one side thereof pushes it to the upper surface of the packaging platform 216. The limiting plate 215 can further limit the position of the paper tube to facilitate the subsequent packaging work of the workers.

[0042] Working principle: During the operation of the device, the paper tube is first chamfered inside the chamfering machine 1. When the paper tube is chamfered from the chamfering machine 1, the chamfering machine 1 pushes the paper tube out, and the paper tube automatically rolls down to the upper surface of the polyurethane roller 29. At this time, the V-shaped rotating device 210 is lifted upward, and the paper tube is supported by the end of the V-shaped rotating device 210 until the paper tube is lifted off the polyurethane roller 29 to a suitable position. Then the roller on the V-shaped rotating device 210 drives the paper tube to rotate. The three straightness measuring instruments 28 are located directly above the paper tube. When the V-shaped rotating device 210 drives the paper tube to rotate, the straightness measuring instrument 28 starts to detect the straightness of the paper tube. At the same time, the straightness measuring instrument 28 transmits real-time data to the PLC, reads the maximum and minimum values ​​in one circle, and then The straightness of the paper tube is calculated. If the values ​​of the three groups are all within the qualified range, the paper tube is qualified. If one of the three groups of data is not within the qualified range, the paper tube is unqualified. After the detection is completed, the V-shaped rotating device 210 descends, and the paper tube falls onto the polyurethane roller 29. Then the roller of the polyurethane roller 29 rotates, and the qualified products and the unqualified products are respectively transmitted in two directions, that is, the qualified and unqualified paper tube products can be separated. The device can detect the single-point straightness of the paper tube online in real time. Compared with the traditional manual detection method, it greatly improves the detection speed and reduces the errors caused by human factors, thereby improving the detection accuracy. At the same time, the inner side of the end of the sliding block 23 is slidably connected with the first fixed column 24 and the second fixed column 25. The first fixed column 24 A threaded connecting rod 26 is fixedly connected to the outer side of the end portion, and the second fixing column 25 is sleeved on the outer surface of the threaded connecting rod 26. An arc groove is opened on the outer side of one end of the first fixing column 24 and the second fixing column 25, and a circular through hole is opened on the inner side of one end of the sliding block 23. The inner wall surfaces of the arc grooves of the first fixing column 24 and the second fixing column 25 are in contact with the outer surface of the sliding rod 22, and the sliding rod 22 can limit the positions of the first fixing column 24 and the second fixing column 25. Because the second fixing column 25 is only slidably connected to the non-threaded part of the threaded connecting rod 26, it conflicts with the threaded part of the threaded connecting rod 26, so that the second fixing column 25 will not fall off the surface of the threaded connecting rod 26, and the sliding rod 22 limits the position of the first fixing column 24, and the first fixing column 24 is not The first nut 27 is rotated to increase the gap between the first fixing column 24 and the second fixing column 25, thereby reducing the pressure of the arc grooves at the ends of the first fixing column 24 and the second fixing column 25 on the sliding rod 22, so that the sliding block 23 can slide on the surface of the sliding rod 22. When the position is suitable, the first nut 27 is rotated in the opposite direction to bring the first fixing column 24 and the second fixing column 25 closer to each other, thereby reducing the distance between the arc grooves of the first fixing column 24 and the second fixing column 25, increasing the pressure of the first fixing column 24 and the second fixing column 25 on the sliding rod 22, and making the inner wall surface of the arc grooves of the first fixing column 24 and the second fixing column 25 press against the outer surface of the sliding rod 22.That is, the fixing of the sliding block 23 is completed. Through the sliding block 23, the first fixing column 24 and the second fixing column 25, the user can arbitrarily adjust the position of the straightness measuring instrument 28 on the sliding rod 22 according to the needs, which increases the flexibility and practicality of the device. At the same time, when the user unscrews the first nut 27 from the outer surface of the threaded connecting rod 26, the straightness measuring instrument 28 will not fall off, further increasing the safety of the device. A servo slide rail 211 is installed on the outer side of the end of the mounting base 21. The V-shaped rotating device 210 penetrates the slide groove and the The servo slide rail 211 is connected to the V-shaped rotating device 210. When the position of the V-shaped rotating device 210 needs to be adjusted, the servo slide rail 211 only needs to be started, and the paper tube 210 is adjusted to the corresponding distance according to the paper tubes of different sizes and models, and the position of the V-shaped rotating device 210 is adjusted. The user can adjust the position of the V-shaped rotating device 210 according to the paper tubes of different sizes, which further increases the flexibility of the device. A baffle 213 is fixedly connected to the outer side of one end of the polyurethane roller 29. The baffle 213 is an arc-shaped structure. The paper tube will roll to the top of the polyurethane roller 29. The baffle 213 can block the paper tube if the moving distance is too long to prevent the paper tube from falling. After the paper tube rises a certain distance on the surface of the baffle 213, it moves in the opposite direction under the action of gravity and returns to the surface of the polyurethane roller 29, which increases the practicality of the device. Two side plates 214 are fixedly connected to the outer side of the end of the chamfering machine 1. The side plates 214 are L-shaped structures. The side plates 214 can ensure that the paper tube will not fall from the ends of the side plates 214. At the same time, the side plates 214 of the L-shaped structure can ensure the rolling stability of the paper tube. The side plates 214 of the L-shaped structure have a certain effect on the paper tube. The position of the paper tube is limited to a certain extent so that the paper tube will not pop out from the end of the chamfering machine 1. The outer sides of the two ends of the polyurethane roller 29 are equipped with a tube pushing device 212 and a conveyor belt 217. A packaging platform 216 is installed on one side of the conveyor belt 217. When the paper tube is transported to the upper surface of the conveyor belt 217 by the polyurethane roller 29, the sensor on the conveyor belt 217 detects that the paper tube is in place, and the tube pushing device 212 on one side of the conveyor belt 217 pushes it to the upper surface of the packaging platform 216. The limit plate 215 can further limit the position of the paper tube, which is convenient for the subsequent packaging work of the workers.
