Description

Technical Field

[0001] This utility model relates to the field of road sign production technology, specifically to a high-efficiency road sign pressing and packaging equipment. Background Technology

[0002] Road traffic signs are graphic symbols that display traffic regulations and road information. They provide a vivid, concrete, and concise expression of traffic regulations, while also conveying information that is difficult to describe in words. These signs are used to manage traffic, indicate driving directions, and ensure smooth traffic flow and road safety. They apply to highways, urban roads, and all special-purpose roads, and have the force of law, which all vehicles and pedestrians must obey.

[0003] To ensure that signs are still visible to drivers and pedestrians at night or in dark conditions, reflective stickers or films are usually affixed to their surface. When applying these stickers or films, a pressing machine is typically used. This machine applies pressure to the reflective film on the sign's surface and holds it for a period of time. To ensure a good adhesion, the larger the sign area, the longer the pressing machine needs to hold the pressure, which reduces production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an efficient road sign pressing and packaging device.

[0005] The technical solution of this utility model is:

[0006] A high-efficiency road sign pressing and sealing device, comprising:

[0007] A workbench includes a pressure table with a bottom mold on its top surface for placing identification signs. The pressure table and bottom mold have adsorption structures. A pressing assembly is located on the rear and top of the pressure table for pressing the identification signs and reflective film. An auxiliary pressing assembly is located between the pressing assembly and the bottom mold, including a rolling structure and a resetting structure. The rolling structure is used to roll the reflective film, and the resetting structure is used to reset the rolling structure.

[0008] Preferably, the adsorption structure includes an air channel located inside the pressure platform. The top surface of the pressure platform is provided with a plurality of air holes, which extend downward into the interior of the pressure platform and connect with the air channel.

[0009] Preferably, the bottom mold has several through holes in the middle, and the through holes correspond to the air holes.

[0010] Preferably, the bottom mold has a boss on the top edge, the height of the boss is lower than the thickness of the sign, the top of the boss has a fixing bolt, and the fixing bolt passes through the boss and is threaded to the air hole.

[0011] Preferably, the pressing assembly includes a first pressure device located directly above the pressure platform, with a pressure plate at the bottom of the first pressure device, and the first pressure device is used to drive the pressure plate to move vertically.

[0012] Preferably, the reset structure includes a rotating rod, the upper end of which is rotatably mounted on the side of the pressure plate via a rotating shaft, and a second pressure device is rotatably mounted between the bottom outer end of the rotating rod and the side of the pressure plate.

[0013] Preferably, two rotating rods are symmetrically installed on each side of the pressure plate, and the top ends of the two rotating rods on the same side are connected by a synchronization structure, and the rolling structure is rotatably installed at the bottom end of the rotating rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes protrusions to limit the position of the sign, ensuring uniform force on the sign during pressing. By setting air channels and air holes, along with through holes, the sign can be fixed by drawing gas from the air channels. A first pressure device drives the pressure plate to descend, allowing the rolling structure to contact the sign. The rolling structure can move outward via a rotating rod. A second pressure device ensures that the rolling structure continuously applies pressure to the sign, reducing subsequent pressure holding time and improving production efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A high-efficiency road sign pressing and sealing device, comprising:

[0029] The workbench 1 includes a pressure table 11, a bottom mold 14 on the top surface of the pressure table 11 for placing the sign, an adsorption structure on the pressure table 11 and the bottom mold 14, a pressing assembly 2 on the rear side and top of the pressure table 11 for pressing the sign and reflective film, and an auxiliary pressing assembly 3 between the pressing assembly 2 and the bottom mold 14, the auxiliary pressing assembly 3 including a rolling structure and a reset structure, the rolling structure for rolling the reflective film and the reset structure for resetting the rolling structure.

[0030] The adsorption structure includes an air passage 12, which is located inside the pressure platform 11. The top surface of the pressure platform 11 is provided with several air holes 13, which extend downward into the interior of the pressure platform 11 and connect with the air passage 12.

[0031] Airway 12 is used to connect a negative pressure device, which can be a known negative pressure fan or other device. The negative pressure device is a known technology and is not shown in the diagram.

[0032] The air in the airway 12 can be extracted to create a negative pressure at the air vent 13.

[0033] The bottom mold 14 has several through holes 15 through the middle, and the through holes 15 correspond to the air holes 13.

[0034] The vent 13 corresponds to the through hole 15. When the vent 13 is in a negative pressure state, the through hole 15 is also in a negative pressure state. When the sign is placed on the bottom mold 14, it can be attracted to the bottom mold 14.

[0035] The bottom mold 14 has a boss 16 on the top edge. The height of the boss 16 is lower than the thickness of the sign. The top of the boss 16 has a fixing bolt 17. The fixing bolt 17 passes through the boss 16 and is threaded to the air hole 13.

[0036] The boss 16 is used to limit the position of the sign and to position the sign.

[0037] When the bottom mold 14 is too small to completely cover the air holes 13, the unused air holes 13 can be sealed with fixing bolts 17.

[0038] The pressing assembly 2 includes a first pressure device 22, which is located directly above the pressure platform 11. A pressure plate 23 is fixedly installed at the bottom of the first pressure device 22 by bolts. The first pressure device 22 is used to drive the pressure plate 23 to move in the vertical direction.

[0039] The first pressure device 22 is vertically installed above the pressure plate 11 via the pressing bracket 21. The first pressure device 22 can be a hydraulic cylinder.

[0040] The upper mold 24 is fixedly installed on the bottom surface of the pressure plate 23 by bolts, and the upper mold 24 matches the bottom mold 14.

[0041] The operation of the first pressure device 22 can drive the pressure plate 23 to move, thereby driving the upper mold 24 to move. When the upper mold 24 moves downward, it can cooperate with the bottom mold 14 to press the sign and reflective sticker.

[0042] The reset structure includes a rotating rod 32. The upper end of the rotating rod 32 is rotatably mounted on the side of the pressure plate 23 via a rotating shaft 31. A second pressure device 36 is rotatably mounted between the bottom outer end of the rotating rod 32 and the side of the pressure plate 23.

[0043] The second pressure device 36 can be a gas spring, and the elastic force of the second pressure device 36 can drive the rotating rod 32 to rotate downward.

[0044] Two rotating rods 32 are symmetrically installed on each side of the pressure plate 23. The top ends of the two rotating rods 32 on the same side are connected by a synchronous structure, and the rolling structure is rotatably installed at the bottom end of the rotating rods 32.

[0045] It includes two meshing teeth 33. After the meshing teeth 33 are engaged, they can ensure that the two rotating rods 32 on the same side rotate synchronously.

[0046] The rolling structure includes a roller shaft 34, on which a roller 35 is rotatably mounted. Both ends of the roller shaft 34 are engaged with rotating rods 32 on both sides of the pressure plate 23. When the rotating rods 32 rotate, they drive the roller shaft 34 to move, thereby moving the roller shaft 34.

[0047] In this embodiment, when the operator uses this device, the sign and reflective film are placed on the base mold 14 and initially positioned using the boss 16.

[0048] Air is extracted from the air passage 12, and the signboard and reflective film are adsorbed using the air hole 13 and the through hole 15.

[0049] The first pressure device 22 is controlled to operate, driving the pressure plate 23 and the upper mold 24 to move downwards. This, in turn, drives the auxiliary pressing assembly 3 to move downwards.

[0050] When the auxiliary pressing component 3 moves downward, the roller 35 will first contact the sign and the reflective film. The roller 35 rolls from the middle of the sign to both sides. The elasticity of the second pressure device 36 will cause the roller 35 to apply pressure to the sign and the reflective film, so that the sign and the reflective film are bonded together.

[0051] When the rotating rod 32 rotates to a horizontal position, the upper mold 24 presses down on the sign and reflective film to maintain pressure.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
