Description

Technical Field

[0001] This utility model relates to the field of laminated glass technology, and more specifically, to a pre-pressing machine for laminated glass. Background Technology

[0002] Laminated glass, as a building and decoration material with superior safety performance, has been widely used in many fields such as modern architecture, automotive industry, and furniture manufacturing. It is made of multiple layers of glass and interlayer materials bonded together through a special process, and has good sound insulation, heat insulation, UV protection, and impact resistance.

[0003] In the production of laminated glass, the pre-compression stage is crucial. Traditional pre-compression methods often rely on manual operation or simple mechanical devices. Manual pre-compression is not only inefficient but also makes it difficult to ensure the uniformity and stability of the pre-compression, easily leading to inconsistent product quality due to differences in operator skill and fatigue. Simple mechanical devices, when clamping and pre-compressing laminated glass, typically suffer from uneven clamping force, inconvenient adjustment, and poor adaptability to laminated glass of different sizes. Utility Model Content

[0004] The purpose of this invention is to provide a pre-pressing machine for laminated glass, which solves the problems of low operation efficiency, uneven clamping force, poor adaptability to different glass sizes, and easy damage to glass in the existing technology.

[0009] Two sets of extrusion assemblies, arranged opposite to each other, are used to clamp laminated glass;

[0010] A drive assembly connects the two sets of extrusion assemblies and is used to move the extrusion assemblies, thereby adjusting the spacing between the extrusion assemblies.

[0011] As a further limitation of this technical solution, the extrusion assembly includes: a connecting plate and a rotating roller, the connecting plate being disposed on the movable end of the drive assembly, and the rotating roller being rotatably disposed on the connecting plate.

The two sets of transmission components correspond one-to-one with the two sets of connecting plates. The transmission component includes a connecting rod and two swing rods. One end of the connecting rod is rotatably connected to the moving rod, and the other end of the connecting rod is rotatably connected to one of the swing rods. The two swing rods are parallel to each other. One end of the two swing rods is rotatably connected to the support frame, and the other end of the two swing rods is rotatably connected to the connecting plate.

[0013] As a further limitation of this technical solution, the driving component is an electric push rod, the housing of the electric push rod is fixedly connected to the support frame, and the piston rod of the electric push rod is connected to the moving rod.

[0014] As a further limitation of this technical solution, the pre-pressing machine also includes a position limiting mechanism, which is used to limit the lateral position of the laminated glass.

[0030] Reference Figures 1 to 3 A pre-pressing machine for laminated glass, comprising:

[0031] The support frame 100 is used for load-bearing and fixing, and can be installed in a suitable position by means of detachment or welding;

[0032] A pre-compression mechanism 200 is disposed on the support frame 100, and the pre-compression mechanism 200 includes:

[0033] Two sets of extrusion assemblies 220 are arranged opposite to each other for clamping laminated glass;

[0034] The drive component 210 connects the two sets of extrusion components 220 and is used to drive the extrusion components 220 to move, thereby adjusting the spacing between the extrusion components 220.

[0035] The extrusion assembly 220 includes a connecting plate 221 and a rotating roller 222. The connecting plate 221 is disposed on the movable end of the drive assembly 210, and the rotating roller 222 is rotatably disposed on the connecting plate 221.

[0036] The drive assembly 210 includes a drive component, a moving rod 212, and two sets of transmission components. The fixed end of the drive component is disposed on the support frame 100, and the other end of the drive component is connected to the moving rod 212. The two sets of transmission components correspond one-to-one with the two sets of connecting plates 221. The transmission components include a connecting rod 213 and two swing rods 214. One end of the connecting rod 213 is rotatably connected to the moving rod 212, and the other end of the connecting rod 213 is rotatably connected to one of the swing rods 214. The two swing rods 214 are parallel to each other. One end of the two swing rods 214 is rotatably connected to the support frame 100, and the other end of the two swing rods 214 is rotatably connected to the connecting plate 221.

[0037] The driving component is an electric push rod 211, the housing of which is fixedly connected to the support frame 100, and the piston rod of which is connected to the moving rod 212.

[0038] Specifically, the electric push rod 211 in the drive assembly 210 is activated, and the piston rod of the electric push rod 211 begins to extend and retract. When the piston rod extends, it pushes the connected moving rod 212 forward. The movement of the moving rod 212 is transmitted to the swing rod 214 through the connecting rod 213. Since one end of the connecting rod 213 is rotatably connected to the moving rod 212 and the other end is rotatably connected to the swing rod 214, and the two swing rods 214 are parallel to each other and rotatably connected to the support frame 100 at one end and to the connecting plate 221 at the other end, the linear motion of the moving rod 212 is converted into the swing motion of the swing rod 214, which in turn drives the two connecting plates 221 to move relative to each other. The two connecting plates 221 drive the rotating roller 222 to move closer to each other, squeezing the laminated glass and controlling the electric push rod 211 to stop moving.

[0039] The pre-pressing machine also includes a position limiting mechanism 300, which is used to limit the lateral position of the laminated glass.

[0040] The position limiting mechanism 300 includes a first bracket 320, two movable parts 330, and a threaded rod 310. The first bracket 320 is fixedly mounted on one of the connecting plates 221, and the two movable parts 330 are slidably mounted on the first bracket 320. The threaded rod 310 is used to thread the two movable parts 330 respectively.

[0041] The threaded rod 310 corresponds to the opposite threads on the two moving parts 330, and is used to drive the two moving parts 330 to move closer or further apart.

[0042] The movable component 330 has a movable block 332 and a limiting post 331. The threaded rod 310 is threadedly connected to the movable block 332, and the limiting post 331 is rotatably mounted on the movable block 332.

[0043] Specifically, the operating position limiting mechanism 300. Rotating the threaded rod 310 causes the two moving blocks 332 to move closer or further apart on the first support 320 due to the opposite threads on the threaded rod 310. The limiting posts 331 on the moving blocks 332 adjust their spacing accordingly, setting it to a suitable distance slightly larger than the width of the laminated glass, thereby providing precise limitation on the lateral position of the laminated glass and preventing lateral displacement during pre-pressing.

[0044] In summary, the implementation principle of this utility model is as follows:

[0045] First, the operating position limiting mechanism 300 is set according to the width of the laminated glass to be pre-pressed. Rotating the threaded rod 310 causes the two moving blocks 332 to move closer or further apart on the first support 320 due to the opposite threads on the threaded rod 310. The limiting posts 331 on the moving blocks 332 adjust their spacing accordingly, setting them to a suitable distance slightly larger than the width of the laminated glass, thereby providing precise limitation on the lateral position of the laminated glass and preventing lateral displacement during pre-pressing.

[0046] Next, the laminated glass is placed between the two sets of extrusion assemblies 220. The electric push rod 211 in the drive assembly 210 is activated, and the piston rod of the electric push rod 211 begins to extend and retract. When the piston rod extends, it pushes the connected moving rod 212 forward. The movement of the moving rod 212 is transmitted to the swing rod 214 through the connecting rod 213. Since one end of the connecting rod 213 is rotatably connected to the moving rod 212 and the other end is rotatably connected to the swing rod 214, and the two swing rods 214 are parallel to each other and rotatably connected to the support frame 100 at one end and the connecting plate 221 at the other end, the linear motion of the moving rod 212 is converted into the swing motion of the swing rod 214, which in turn drives the two connecting plates 221 to move relative to each other. The two connecting plates 221 drive the rotating roller 222 to move closer to each other, squeezing the laminated glass and stopping the electric push rod 211 from moving.

[0047] The upper and lower rotating rollers 222 apply clamping force evenly to the laminated glass, pushing the laminated glass to move on the rotating rollers 222, pre-pressing the laminated glass, making the layers of the laminated glass tightly bonded, expelling the air in the middle and initially fixing the interlayer structure.

[0048] After pre-pressing is completed, the piston rod of the electric push rod 211 retracts in the opposite direction, driving the moving rod 212 to retract. Through the transmission of the connecting rod 213 and the swing rod 214, the connecting plates 221 of the two sets of extrusion components 220 move in opposite directions, and the rotating roller 222 releases the laminated glass. At this time, the pre-pressed laminated glass can be taken out, completing the entire pre-pressing process.

[0049] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
