DETAILED DESCRIPTION

[0018] The utility model will be further described below in combination with the drawings.

[0019] The utility model discloses a pressing beam device of the edge banding machine, as shown in the drawing, Figures 1 to 3 , comprising pressing beam 1, pressing beam lifting mechanism 2, transmission shaft 3, and the pressing beam 1 is arranged along the left and right direction (i.e. is arranged along the longitudinal direction), and the bottom of the pressing beam 1 is equipped with the pressing wheel 7, and the pressing wheel 7 is arranged along the extension direction of the pressing beam 1, and the pressing beam lifting mechanism 2 is arranged at intervals along the extension direction of the pressing beam 1, and under the visual direction of Figure 1 , the pressing beam lifting mechanism 2 is arranged at intervals along the left and right direction. As shown in Figure 2 And Figure 3 , the pressing beam lifting mechanism 2 includes lifting seat 22, and the lifting seat 22 is installed and connected pressing beam 1, and specifically, the pressing beam 1 is made of aluminum profile, and the front side of the pressing beam 1 is formed with T-shaped groove, and the lifting seat 22 is connected to the front of the pressing beam 1, and then the screw is screwed with the square nut arranged in the T-shaped groove by screwing through the mounting hole on the lifting seat 22 and then screwing. As shown in Figure 1As shown, the beam pressing device further comprises a lifting driving motor 4 for driving the lifting seat 22 to move up and down, and adjacent beam pressing lifting mechanisms 2 are respectively connected through corresponding transmission shafts 3, the lifting driving motor 4 drives the corresponding transmission shaft 3 to rotate, in other words, the beam pressing lifting mechanism 2 can convert rotation into linear (up and down) movement, so for example, the beam pressing lifting mechanism 2 can comprise a bevel gear pair, a stud and a sleeve, the stud is screwed with the sleeve, the sleeve is fixed with the bevel gear along the up and down direction, the transmission shaft 3 is coaxially connected with the bevel gear along the left and right direction, so that the transmission shaft 3 drives the bevel gear along the left and right direction to rotate, the bevel gear along the left and right direction drives the bevel gear along the up and down direction to rotate, so that the sleeve rotates, the stud is fixedly arranged, and the sleeve and the bevel gear pair are arranged on the lifting seat 22, so that the lifting seat 22 can move up and down to adjust the position. Figure 1 As shown, specifically, the output rotating shaft of the lifting driving motor 4 is connected with the input end of the right-angle speed reducer, the output end of the right-angle speed reducer is a hollow shaft, the transmission shaft 3 is adapted to pass through the hollow shaft and is connected with the hollow shaft through a flat key, and the transmission principle of the right-angle speed reducer can refer to the "high-precision right-angle speed reducer" with the publication number CN204828493U of the Chinese utility model patent. Figure 1 and Figure 3 As shown, the beam 1 is formed with a beam top surface 101, the upper side of the beam 1 is provided with a laser displacement sensor 6 for detecting the beam top surface 101, the laser displacement sensors 6 are arranged at intervals along the extension direction of the beam 1, and the laser displacement sensor 6 is a product of the prior art; the beam pressing device further comprises a control system and an alarm, the control system is electrically connected with the laser displacement sensor 6, and the control system controls the connection of the alarm.

[0020] The working principle of the utility model is briefly described as follows: in the assembly process, the beam 1 is arranged in parallel with the chain plate supporting beam 99, and each laser displacement sensor 6 is arranged at zero position; as shown in Figure 1As shown, the lifting driving motor 4 operates, and the lifting driving motor 4 drives the corresponding transmission shaft 3 to rotate through the above-mentioned right-angle speed reducer. Since the adjacent pressing beam lifting mechanisms 2 are respectively connected through the corresponding transmission shaft 3, that is to say, each pressing beam lifting mechanism 2 can operate synchronously, so that each lifting seat 22 synchronously lifts, and then the pressing beam 1 can be lifted and positioned. In the process of lifting and moving the pressing beam 1, the laser displacement sensors 6 respectively monitor the displacement of the corresponding parts of the pressing beam 1. In theory, if the pressing beam 1 always keeps parallel with the chain plate supporting beam 99, the measurement values of each laser displacement sensor 6 will keep the same. If the difference between the measurement values of any two laser displacement sensors 6 exceeds the limit, it means that the corresponding parts of the pressing beam 1 to the laser displacement sensors 6 are inconsistent in height, that is, the pressing beam 1 is bent or inclined (that is, the heights of the left and right ends of the pressing beam 1 are inconsistent). The control system accordingly controls the alarm to issue a warning, so that the operator can find the bad state of the pressing beam 1 in time, and the operator can stop the machine in time for processing, avoiding that the relative looseness between the plate 97 and the chain plate 98 leads to that a large number of unqualified plates 97 are processed, and also avoiding that the functional components of the edge banding machine are damaged and the personnel are hurt. Therefore, the pressing beam device is beneficial to safety production. The early deformation of the pressing beam 1 can be found in time through the laser displacement sensor 6, and the technician can maintain the pressing beam device, so that the plastic deformation of the pressing beam 1 can be avoided.

[0021] Further, as shown in the figure, Figure 3 The pressing beam lifting mechanism 2 comprises a vertical seat 21 and a linear guide pair 24. The lifting seat 22 is connected to the vertical seat 21 through the linear guide pair 24. The lower end of the vertical seat 21 is installed on the bed of the edge banding machine through corresponding screws. Specifically, the guide rail of the linear guide pair 24 is installed at the rear end of the vertical seat 21, and the sliding block of the linear guide pair 24 is installed on the front side of the lifting seat 22. Through the setting of the linear guide pair 24, the lifting seat 22 can move up and down with high rigidity.

[0022] Further, as shown in the figure, Figure 2 The pressing beam lifting mechanism 2 comprises a screw lifter 23. The screw lifter 23 comprises a screw rod 25, a worm wheel, a worm and a nut. The worm wheel is connected with the worm in meshing mode (the internal structure of the screw lifter 23 is not shown). The nut is coaxially arranged with the worm wheel. The nut is fixedly arranged relative to the worm wheel. The nut and the worm wheel can be integrally arranged. The screw lifter 23 is installed on the top of the lifting seat 22. Specifically, the shell of the screw lifter 23 is installed on the upper side of the mounting plate 221 at the upper end of the lifting seat 22. The lifting seat 22 has a groove structure. The screw rod 25 is arranged in the groove structure. The screw rod 25 is vertically arranged. The lower end of the screw rod 25 is fixedly connected with the vertical seat 21. The screw rod 25 is screwed with the nut. The left and right ends of the screw lifter 23 are respectively provided with input shafts 231. The input shafts 231 are coaxially and fixedly arranged with the worm. The worm can be integrally arranged with the input shaft 231, as shown in the figure, Figure 1As shown, the input shaft 231 is connected (i.e., connected via a coupling) to the ends of the corresponding transmission shaft 3. Therefore, when the transmission shaft 3 connected to the lifting drive motor 4 rotates, the transmission shaft 3 drives the input shaft 231 on one side of the screw jack 23 to rotate synchronously, and the input shaft 231 on the other side of the screw jack 23 can then drive the corresponding transmission shaft 3 to rotate synchronously, and so on. Specifically, as... Figure 1 As shown, the input shaft 231 on the left side of the screw jack 23 of the first pressure beam lifting mechanism 2 from left to right is not connected to the drive shaft 3, and the input shaft 231 on the left side of the screw jack 23 of the first pressure beam lifting mechanism 2 from right to left is not connected to the drive shaft 3. By setting the screw jack 23 as described above, the worm gear drive has good self-locking performance, which helps the pressure beam 1 to be stabilized at its height position. Since the worm gear drive is easy to set a large reduction ratio, it is beneficial to set the lifting drive motor 4 with a smaller power, and it is also beneficial to reduce the torque on the drive shaft 3, which helps to reduce the elastic torsional deformation of the drive shaft 3, thus improving the synchronous lifting performance of each lifting seat 22.

[0023] Furthermore, such as Figure 3 As shown, the beam-pressing device of this utility model also includes a sensor support 5, a laser displacement sensor 6 is mounted on the corresponding sensor support 5, and the sensor support 5 is mounted on the corresponding upright 21, as shown. Figure 4 As shown, the sensor support 5 includes a longitudinal plate 51, a transverse plate 52, and a vertical plate 53. One end of the longitudinal plate 51 is mounted on the top of the support 21, and the corresponding other end of the longitudinal plate 51 is welded to the lower end of the vertical plate 53. The upper end of the vertical plate 53 is welded to the front end of the transverse plate 52. The laser displacement sensor 6 is mounted on the rear end of the transverse plate 52, so that the laser displacement sensor 6 can be located above and behind the drive shaft 3. (Note that this is for ease of viewing.) Figure 3 The screw jack 23 is not shown. Since the sensor support 5 is mounted on the corresponding stand 21, it avoids the need for a separate structure to support the sensor support 5.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, the lifting seat 22 is located behind the upright seat 21. The upright seat 21 has a protruding support arm 211. The lower end face of the screw 25 abuts against the protruding support arm 211. A clamp 212 is installed on the protruding support arm 211 by corresponding screws. The clamp 212 clamps the lower end of the screw 25, which facilitates quick fixing of the screw 25. Specifically, as shown... Figure 5As shown, the clamping seat 212 is formed with a clamping hole 2121 and a slit 2122, one end of the slit 2122 communicates with the clamping hole 2121, and the other end of the slit 2122 penetrates through the clamping seat 212, the lower end of the screw rod 25 is adapted to be arranged in the clamping hole 2121, the clamping seat 212 is installed with a clamping screw 2123, the clamping screw 2123 is used to pull the two sides of the slit 2122 close, that is, to narrow the slit 2122, so that the clamping hole 2121 can clamping and fixing the screw rod 25.
