[0023] Specifically, the lifting and collecting device 7 includes a connecting frame 71, a screw rod 72, a collecting assembly 73, a lifting box 74, a mesh plate 75 and a rotating plate 76. The lifting box 74 is arranged between the two outer limit blocks 4 and the two cylinder assemblies 6 and the moving assembly 2. The two outer limit blocks 4 and the two cylinder assemblies 6 are connected to the lifting box 74 through the mesh plate 75. A connecting frame 71 is arranged on the outside of the lifting box 74. A screw rod 72 is installed on the connecting frame 71 and is located on the inner side of one end of the lifting box 74 through a bearing. A rotating plate 76 is installed above the screw rod 72. The collecting assembly 73 is installed at the bottom of the lifting box 74 and is located on one side of the connecting frame 71.

[0024] By adopting the above technical solution, the staff can adjust the height of the limited workpiece to a certain extent through the cooperation of the screw rod 72 and the lifting box 74 and other structures when necessary, so as to better meet the work needs in different situations.

[0025] Specifically, one side of the lifting box 74 and the inner side of the connecting frame 71 are in close contact with each other.

[0026] By adopting the above technical solution, the mechanism can limit and guide the movement of the lifting box 74 to a certain extent through the connecting frame 71, thereby preventing the lifting box 74 from rotating and deviating during the movement, and ensuring the normal operation.

[0027] Specifically, the collecting assembly 73 includes a battery 731, a fan 732, a filter cloth 733 and a threaded barrel 734. The threaded barrel 734 is threadedly installed at the bottom of the lifting box 74 and at a position on one side of the connecting frame 71. The filter cloth 733 is installed on the inner side of the threaded barrel 734. The fan 732 is installed below the threaded barrel 734, and a battery 731 is installed on one side of the fan 732.

[0028] By adopting the above technical solution, the mechanism can collect and process the debris and dust in the milling process through the cooperation of the fan 732 and the filter cloth 733 when necessary, and the battery 731 plays the role of power supply.

[0029] When the present embodiment is used, when the pre-milling device of the edge banding machine needs to use a mechanism to limit the workpiece, the moving assembly 2 on the base 1 is started to adjust the position of the cylinder assembly 6 and other structures, and the slider 3 plays a guiding role. Then the staff manipulates the rotating plates 76 in the two rotating lifting collection devices 7, and the rotating plates 76 drive the screw rod 72 to rotate. The screw rod 72 is threadedly connected to the lifting box 74, and the lifting box 74 is close to the connecting frame 71, so the screw rod 72 drives the lifting box 74 and other structures to move, thereby adjusting the height of the cylinder assembly 6 and other structures. The workpiece is then placed on the mesh plate 75, and the cylinder assembly 6 is started to drive the inner limit block 5 to move. The inner limit block 5 cooperates with the outer limit block 4 to limit the workpiece, thereby performing work. During the pre-milling process, the staff can start the fan 732 in the collection assembly 73. Under the action of the fan 732, the debris and dust generated during the pre-milling process pass through the mesh plate 75 and the lifting box 74 and enter the threaded barrel 734, and then the debris and dust are blocked by the filter cloth 733 and remain in the threaded barrel 734, and the battery 731 plays a role in power supply.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the position adjustment device 8 includes a connecting box 81, a moving block 82, a screw 83 and a knob 84, the connecting box 81 is installed on the side of the moving component 2 and the two sliders 3 close to the connecting frame 71, the moving block 82 is installed below the connecting frame 71 and at a position inside the connecting box 81, the screw 83 is installed on one side of the moving block 82 through a bearing, and the knob 84 is installed on the side of the screw 83 away from the moving block 82.

[0032] By adopting the above technical solution, the staff can adjust the position of the external limit block 4 and other structures by cooperating with the moving block 82 and the screw rod 83 and other structures when necessary, so as to better meet the work needs in different situations.

[0033] Specifically, the height of the inner bottom surface of the connection box 81 is equal to the height of the outer bottom surface of the moving block 82 .

[0034] By adopting the above technical solution, it is ensured that the inner bottom surface of the connection box 81 and the outer bottom surface of the moving block 82 can be closely attached to each other, thereby preventing the moving block 82 from rotating and deviating during the movement process.

[0035] When this embodiment is in use, when it is necessary to further adjust the position of the cylinder assembly 6 and other structures, the staff can turn the knob 84 in the position adjustment device 8, thereby driving the screw 83 to rotate. The screw 83 is threadedly connected to the connecting box 81, and the screw 83 is bearing-connected to the moving block 82. The outer bottom surface of the moving block 82 is close to the inner bottom surface of the connecting box 81, so the screw 83 drives the moving block 82 and the structure thereon to move, thereby further adjusting the position of the cylinder assembly 6 and other structures, thereby better meeting the work needs in different situations.

[0036] The structure and principle of the base 1 and the structure thereon, the moving assembly 2 composed of a slider, a first screw and a first motor, the slider 3, the outer limit block 4, the inner limit block 5, and the cylinder assembly 6 composed of a fixed block and a second cylinder in the utility model have been disclosed in a multi-station limit tooling for precision sand mold milling processing disclosed in Chinese patent application No. 202220895216.9. Its working principle is that when it is necessary to adjust the processing position of the workpiece to be processed, the first motor is controlled by the controller to rotate the first screw fixedly connected to the motor shaft of the first motor, so that the slider threadedly connected to the first screw slides in the slide groove, thereby driving the base to adjust the position on the base, so as to facilitate the adjustment of the processing position of the workpiece to be processed fixed on the base to meet different processing requirements.

[0037] The working principle and use process of the utility model are as follows: when the pre-milling device of the edge banding machine needs to use a mechanism to limit the workpiece, the moving component 2 on the base 1 is started to adjust the position of the cylinder component 6 and other structures, and the slider 3 plays a guiding role. Then the staff manipulates the rotating plates 76 in the two rotating lifting collection devices 7, and the rotating plates 76 drive the screw rod 72 to rotate. The screw rod 72 is threadedly connected to the lifting box 74, and the lifting box 74 is close to the connecting frame 71, so the screw rod 72 drives the lifting box 74 and other structures to move, thereby adjusting the height of the cylinder component 6 and other structures, and then the workpiece is placed on the mesh plate 75, and the cylinder component 6 is started to drive the inner limit block 5 to move. The inner limit block 5 cooperates with the outer limit block 4 to limit the workpiece, so as to work. During the pre-milling process, the staff can start the collection group The fan 732 in the component 73, under the action of the fan 732, the debris dust generated during the pre-milling process passes through the mesh plate 75 and the lifting box 74 into the threaded barrel 734, and then the debris dust is blocked by the filter cloth 733 and remains in the threaded barrel 734, and the battery 731 plays a role in power supply; when it is necessary to further adjust the position of the cylinder assembly 6 and other structures, the staff can turn the knob 84 in the position adjustment device 8, thereby driving the screw 83 to rotate, the screw 83 is threadedly connected to the connecting box 81, the screw 83 is bearing-connected to the moving block 82, and the outer bottom surface of the moving block 82 is close to the inner bottom surface of the connecting box 81, so the screw 83 drives the moving block 82 and the structure thereon to move, and then further adjusts the position of the cylinder assembly 6 and other structures, thereby better meeting the work needs in different situations.
