Description

Technical Field

[0001] This utility model relates to the field of picture frame processing technology, and in particular to a corner nailing device for an art painting frame. Background Technology

[0002] Picture frames primarily serve to protect the quality of photographs and prevent them from discoloring or yellowing. In modern life, various types of picture frames have also become an important part of decoration. During assembly, a corner-pinning machine is often needed to fix two frames at specific angles together.

[0003] Chinese Patent CN219748348U discloses a frame corner nailing machine. It includes an operating table, a positioning device, and a fastening device. The fastening device includes a mounting block, an adapter structure, and a driving structure. The adapter structure has multiple components, including an adapter rod, a clamping block, and a power component. When the frame rod is placed in a preset position on the operating table, the driving structure drives the mounting block downwards. As the mounting block moves downwards, the lower end of the adapter rod abuts against the uneven end face of the frame rod and is lifted up. After the lower end of the adapter rod and the uneven end face of the frame rod are matched, the power component drives the arc surface of the clamping block to abut against the upper end of the adapter rod. This causes the clamping block and the adapter rod to engage threadedly, preventing the adapter rod from moving. This allows the extension length of the adapter rod to be adjusted according to the unevenness of the frame rod surface, ensuring uniform pressure on the frame rod surface and preventing damage to the coating due to uneven pressure.

[0004] However, the above technical solution has the following shortcomings: some picture frames are designed with different angles, such as rhombuses, according to customer needs, and this device cannot meet the customer's needs for nailing corners. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an art painting frame corner nailing device that adjusts the frame to a suitable angle using a preliminary adjustment component for corner nailing. If the frame width is large, the user can adjust the frame position using a movable secondary component while fixing the frame angle, thereby performing secondary corner nailing.

[0006] The technical solution of this utility model is a corner-pinning device for an art painting frame, comprising: a frame on which a guide rail, a pressing component, and a corner-pinning component are disposed; a preliminary adjustment component, which includes a motor disposed on the frame, a drive frame disposed on the output end of the motor, and a driven frame meshing with the drive frame; a secondary engagement component, which is slidably disposed on the guide rail; and the corner-pinning component is distributed between the preliminary adjustment component and the secondary engagement component.

[0007] Preferably, the drive frame includes a drive frame main body, inclined block portions and widening block portions disposed on both sides of the drive frame main body; the drive frame main body has a gear portion, and the drive frame and the driven frame have the same structure.

[0008] Preferably, the secondary mating assembly includes a sliding block slidably disposed on the guide rail, an extension frame disposed on the sliding block, two abutment blocks rotatably disposed on the extension frame, an adjusting block slidably disposed on the sliding block, two telescopic blocks slidably disposed on the adjusting block, and two fixing bolts threadedly connected to the adjusting block; the two telescopic blocks are rotatably connected to the two abutment blocks in a one-to-one correspondence, and the two fixing bolts abut against the two telescopic blocks in a one-to-one correspondence.

[0009] Preferably, both abutting blocks have widened sections.

[0010] Preferably, both the sliding block and the adjusting block have positioning components.

[0011] Preferably, the pressing assembly includes multiple pneumatic cylinders mounted on the frame, a mounting plate mounted on the pneumatic cylinders, two pressing frames that are slidably mounted on the mounting plate, a pulling block mounted on the two pressing frames, and an elastic pad mounted at the bottom of each of the two pressing frames.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] In use, the user controls the motor to rotate the drive frame, which in turn drives the driven frame to rotate synchronously, adjusting it to the desired angle. The user then fixes the painting frame to the drive and driven frames using the pressing assembly. The corner-nailing assembly then nails the corners of the painting frame. If the painting frame is wide, the user can use a secondary cooperating assembly to restrict its position. After the pressing assembly resets, it can be used again with the corner-nailing assembly to complete the corner-nailing, thus expanding the applicability of the device. Attached Figure Description

[0018] Example 1

[0019] like Figures 1-3 As shown, this embodiment proposes an art painting frame corner nailing device, including a frame 1, a preliminary adjustment component 9, and a secondary engagement component 8. The frame 1 is provided with a guide rail 7, a pressing component, and a corner nailing component 10. The preliminary adjustment component 9 includes a motor 91 mounted on the frame 1, a drive frame 92 mounted on the output end of the motor 91, and a driven frame 93 meshing with the drive frame 92. The secondary engagement component 8 is slidably mounted on the guide rail 7. The corner nailing component 10 is distributed between the preliminary adjustment component 9 and the secondary engagement component 8.

[0020] The drive frame 92 includes a drive frame main body 921, an inclined block 923 and a widening block 922 disposed on both sides of the drive frame main body 921; the drive frame main body 921 has a gear part, the drive frame 92 and the driven frame 93 have the same structure, the frame of the picture frame will always abut against the widening block 922, the widening block 922 can prevent the picture frame from contacting the gear part, thereby avoiding affecting the corner nailing effect of the picture frame.

[0021] In this embodiment, the user controls the motor 91 to drive the drive frame 92 to rotate, and the drive frame 92 drives the driven frame 93 to rotate synchronously until the included angle between the drive frame 92 and the driven frame 93 meets the user's needs. Then, the user abuts the picture frame against the drive frame 92 and the driven frame 93, and the pressing component cooperates to fix the picture frame. Then, the corner nailing component 10 nails the corners of the picture frame. If the width of the picture frame is large and it is difficult to nail the corners in one go, the user can push the secondary cooperating component 8 to abut against the picture frame. The position of the picture frame is restricted by the secondary cooperating component 8. At the same time, the pressing component resets. After the picture frame is moved, the pressing component and the corner nailing component 10 cooperate to nail the corners, thereby improving the versatility of the device.

[0022] Example 2

[0023] like Figure 1 and Figure 3 As shown, the art painting frame corner nailing device proposed in this embodiment, compared with the first embodiment, in this embodiment, the secondary mating component 8 includes a sliding block 81 slidably disposed on the guide rail 7, an extension frame 82 disposed on the sliding block 81, two abutment blocks 83 rotatably disposed on the extension frame 82, an adjusting block 84 slidably disposed on the sliding block 81, two telescopic blocks 85 slidably disposed on the adjusting block 84, and two fixing bolts 86 threadedly connected to the adjusting block 84; the two telescopic blocks 85 are rotatably connected to the two abutment blocks 83 in a one-to-one correspondence, and the two fixing bolts 86 abut against the two telescopic blocks 85 in a one-to-one correspondence.

[0024] Both abutment blocks 83 have widened block portions 922. Both sliding block 81 and adjusting block 84 have positioning components.

[0025] In this embodiment, the user pushes the sliding block 81 toward the picture frame, and the extension bracket 82 abuts against the picture frame. Then, the user rotates the two abutment blocks 83 so that the widened block portion 922 of the two abutment blocks 83 is completely abutted against the picture frame. Then, the position of the telescopic block 85 is fixed by the fixing bolt 86. The positioning principle of the positioning component is the same as the fixing method of the fixing bolt 86. Then, the user fixes the angle between the two abutment blocks 83 by the positioning component. After that, the user adjusts the position of the sliding block 81 according to the user's needs, thereby improving the adjustability of the device.

[0026] Example 3

[0027] like Figure 1 As shown, the art painting frame corner nailing device proposed in this embodiment, compared with the first embodiment, in this embodiment, the pressing component includes multiple pneumatic cylinders 2 set on the frame 1, a mounting plate 3 set on the pneumatic cylinders 2, two pressing frames 4 slidably set on the mounting plate 3, a pulling block 5 set on the two pressing frames 4, and an elastic pad 6 set at the bottom of each of the two pressing frames 4.

[0028] In this embodiment, the user can adjust the position of the pressure bracket 4 to adjust the pressure component according to the thickness of the picture frame. The pressure bracket 4 is fixed by adjustable bolts after sliding. When the elastic pad 6 contacts the picture frame, it can absorb the impact force of the nail corner of the picture frame and reduce the vibration of the device.
