Description

Technical Field

[0001] This utility model relates to the field of acrylic hot bending equipment, and in particular to an acrylic hot bending device for sign production. Background Technology

[0002] Currently, acrylic sheets are widely used in signage, advertising displays, and handicrafts due to their excellent transparency, weather resistance, and processing performance. In the signage production process, flat acrylic sheets often need to be heat-bent to create specific angles or curved shapes.

[0003] Currently, existing acrylic hot bending equipment typically uses a heater to locally heat and soften the part of the sheet to be bent, and then bends it using a mold or manually. During this process, in order to ensure the accuracy and consistency of the bending angle, the sheet needs to be effectively positioned and limited. However, traditional limiting mechanisms are mostly fixed structures, and the distance between the limiting blocks is not adjustable. When it is necessary to produce signs of different sizes and bending positions, it is necessary to change different limiting molds or adjust the installation position of the entire limiting mechanism. This operation is cumbersome, time-consuming, and labor-intensive, which seriously affects production efficiency. Utility Model Content

[0005] (II) Technical Solution The purpose of this utility model is to provide an acrylic hot bending device for sign production, which includes a frame, a worktable on the upper surface of the frame, a hot bending mechanism on the upper end of the worktable, a first limiting mechanism and a second limiting mechanism on both sides of the hot bending mechanism, and a spacer square tube between the hot bending mechanism and the first and second limiting mechanisms. The first limiting mechanism and the second limiting mechanism are respectively installed on the upper surface of the worktable. The first limiting mechanism includes a first mounting base, a first limiting block and a second limiting block. The first limiting block and the second limiting block are both located on the upper surface of the first mounting base. A third limiting block is provided inside the second limiting mechanism. The relative distance between the first limiting block and the second limiting block is adjustable.

[0006] Preferably, the surface of the workbench is provided with mounting screw holes.

[0007] Preferably, the hot bending mechanism includes a heating wire, a metal sheath tube, an insulating filler layer, and a lead-out rod. There are two metal sheath tubes.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] The following is in conjunction with the appendix Figures 1 to 6To further describe, this utility model discloses an acrylic hot bending device for the production of signboards, including a frame 1. A worktable 2 is screwed onto the upper surface of the frame 1. A hot bending mechanism 3 is horizontally laid on the upper surface of the worktable 2. A first limiting mechanism 4 and a second limiting mechanism 5 are respectively provided on both sides of the hot bending mechanism 3. A spacer square tube 6 is provided between the hot bending mechanism 3 and the first limiting mechanism 4 and the second limiting mechanism 5 by bonding, screwing, or welding. The spacer square tube 6 is used to limit the movement of the hot bending mechanism 3. The limiting mechanism 4 and the second limiting mechanism 5 are respectively installed on the upper surface of the workbench 2. The first limiting mechanism 4 includes a first mounting base 40, a first limiting block 45 and a second limiting block 49. The first limiting block 45 and the second limiting block 49 are both located on the upper surface of the first mounting base 40.

The spacing between the two limiting blocks can be flexibly and quickly adjusted according to the required width of the sign 7 or the specific bending line position.

[0020] In a preferred embodiment, the surface of the worktable 2 is provided with mounting screw holes 20. There are two or more mounting screw holes 20, which are arranged below the first limiting mechanism 4 and the second limiting mechanism 5, and are adapted to the mounting bolts 46 on the first limiting block 45, the second limiting block 49 and the third limiting block 54, respectively.

[0021] In a preferred embodiment, the hot bending mechanism 3 includes a heating wire 30, a metal sheath tube 31, an insulating filling layer 32, and a lead-out rod 33. There are two metal sheath tubes 31. The heating wire 30 is disposed between the two metal sheath tubes 31. An insulating filling layer 32 is disposed between the heating wire 30 and the metal sheath tube 31. The end of the heating wire 30 is connected to the lead-out rod 33, and the lead-out rod 33 is connected to a power cord. The remaining undescribed parts of the hot bending mechanism 3 are prior art.

[0022] In a preferred embodiment, the first mounting base 40 includes a base body 41, a first stop block 43, a second stop block 44, and an adjustable strip hole 42. The first stop block 43 and the second stop block 44 are respectively mounted on opposite sides of the base body 41. There are two adjustable strip holes 42, which are respectively located at both ends of the base body 41 and are adapted to the mounting bolts 46 provided on the first limiting block 45 and the second limiting block 49.

[0023] In a preferred embodiment, scales (not shown) are provided on both sides of the base 41. The scales can be used as a reference to adjust to the corresponding distances, and then each limiting block is fixed by mounting bolts 46.

[0024] In a preferred embodiment, the first limiting block 45, the second limiting block 49, and the third limiting block 54 have the same structure. The first limiting block 45 includes mounting bolts 46, a limiting tube 47, and a scratch-resistant sponge layer 48. There are two mounting bolts 46, which are respectively set at both ends of the limiting tube 47. The mounting bolts 46 are inserted into and pass through the limiting tube 47, and then pass through the seat 41 or the second mounting seat 50 to connect with the mounting screw holes 20 provided on the surface of the workbench 2. The scratch-resistant sponge layer 48 is fixed to the upper end face of the limiting tube 47 by adhesive to prevent the metal limiting tube 47 from scratching the surface of the nameplate 7.

[0025] In a preferred embodiment, the second limiting mechanism 5 further includes a second mounting base 50, a third stop 52, and a fixed limiting block 53. The third stop 52 and the fixed limiting block 53 are respectively bonded to the two sides of the second mounting base 50.

[0027] like Figure 6 As shown, this embodiment features a dual-station design. The operator uses the hot bending mechanism 3 to locally heat and soften the sheet-like acrylic plate, then bends it and places it between the first limiting block 45 and the second limiting block 49, or between the third limiting block 54 and the fixed limiting block 53. The two sides of the bottom of the label 7 are respectively abutted against the edges between the first limiting block 45 and the second limiting block 49, or between the third limiting block 54 and the fixed limiting block 53, ensuring the consistency of the bottom dimensions of the label 7. Since the first limiting mechanism 4 includes the first limiting block 45 and the second limiting block 49, the third limiting block 54 and the fixed limiting block 53 with adjustable relative distances, the operator can flexibly and quickly adjust the distance between the two limiting blocks according to the required width of the label 7 or the specific bending line position. This not only reduces the scrap rate caused by inaccurate positioning, but also eliminates the cumbersome steps of changing and adjusting tooling fixtures in the traditional method, significantly shortening the production preparation time and thus improving overall production efficiency.
