Description

Technical Field

[0001] The utility model belongs to the field of glass processing, in particular to a laminated glass anti-overflow glue structure. Background Art

[0002] Laminated glass is made of two or more pieces of glass and is widely used in buildings. It has the effects of windproofing, light transmission, heat insulation and noise reduction. The wet production process of laminated glass is to add special laminated glass glue between two or more pieces of glass. After adding the glue, it is cured and permanently bonded into a laminated glass. In the production process of laminated glass, an anti-overflow glue structure is required to prevent the glue from overflowing from the sides and causing waste.

[0003] Among them, the publication number CN213266296U is named as a glue overflow prevention structure for laminated glass processing, comprising a fixed frame, a positioning slot is provided on the inner side of the fixed frame, the two sides of the inner surface of the bottom of the positioning slot are respectively fixedly connected with a first limiting protrusion and a second limiting protrusion, the two sides of the inner wall of the fixed frame are slidably connected with side limiting protrusions corresponding to the first limiting protrusion and the second limiting protrusion, the two sides of the outer wall of the fixed frame are respectively installed with a first fixed handle and a second fixed handle, the two sides of the bottom of the fixed frame are respectively fixedly connected with a first rotating bracket and a second rotating bracket, and the two sides of the front and rear ends of the fixed frame are bonded with rubber protective strips. The glue overflow prevention structure for laminated glass processing is not only designed with glue overflow prevention and limiting mechanisms, but also with protective mechanisms, which can not only play a good role in limiting and positioning the glass before gluing, but also play a good role in protecting the glass, and is worthy of vigorous promotion.

[0004] The size and position of the anti-overflow glue structure in the above-mentioned prior art are fixed, which is not conducive to adaptive adjustment for processing laminated glass with different numbers of layers and sizes. It can only be used for processing laminated glass with the same size and number of layers, resulting in great limitations in its use. In addition, the clamping degree of the laminated glass cannot be adaptively adjusted. Too loose or too tight clamping will affect the quality of laminated glass production. Therefore, we propose a laminated glass anti-overflow glue structure to solve the above-mentioned problems. Utility Model Content

[0005] In view of this, the utility model aims to provide a laminated glass anti-overflow glue structure, in order to solve at least one of the above-mentioned technical problems.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] A laminated glass anti-overflow glue structure comprises a lower anti-overflow seat, the upper side of which is bonded with a lower PVB film strip, the front side of which is rotatably connected with a bidirectional screw rod, the outer sides of the left and right ends of the bidirectional screw rod are both threadedly connected with side anti-overflow seats, and the inner side of the side anti-overflow seat is bonded with a side PVB film strip;

[0008] A driving rod passes through the side walls of the side overflow prevention seat, and a pressure roller is installed on the end of the driving rod. The pressure roller is elastically connected to the side overflow prevention seat through a tension spring. The side overflow prevention seat is provided with a driving component for adjusting the clamping degree of the laminated glass injection and curing.

[0009] Furthermore, the driving assembly includes a limiting rod installed on the outside of the side overflow prevention seat, the outside of the limiting rod is slidably connected to a connecting frame, the end of the connecting frame is connected to a moving rod, and a bump is installed on the outside of the moving rod.

[0011] Furthermore, the lower PVB film strip and the side PVB film strip are distributed perpendicularly to each other, and the lower ends of the lower PVB film strip and the side PVB film strip are attached to each other.

[0012] Furthermore, the side anti-overflow seat is a side "U"-shaped structure, the lower end of the side anti-overflow seat passes through the lower anti-overflow seat and is slidably connected with the lower anti-overflow seat, and the lower anti-overflow seat is a "U"-shaped structure.

[0014] Furthermore, the position of the protrusion and the position of the driving rod are arranged in one-to-one correspondence, and the protrusion is a trapezoidal structure.

[0015] Compared with the prior art, the laminated glass anti-overflow glue structure described in the utility model has the following beneficial effects:

[0016] The rotation of the bidirectional screw with opposite thread distribution directions at the end is used to control the movement of the side anti-overflow seats and adjust the spacing between the side anti-overflow seats so that the side anti-overflow seats can adapt to the size of the glass and fit the side edges of the glass. The lower PVB film strip and the side PVB film strip are used to enclose the edge of the laminated glass to avoid glue overflow during glue injection of the laminated glass.

[0017] The connecting frame is driven downward, and the two sets of connecting frames can be moved synchronously by transmission of the adjusting rod and the connecting rod, so as to control the moving rod to drive the convex block to move, push the driving rod, and then control the pressure roller to clamp and fix the laminated glass. The clamping degree of the pressure roller is adjustable, and the squeezing force on both sides of the laminated glass is the same, so as to avoid damage to the laminated glass due to uneven force.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] like Figure 1-5 As shown: an anti-overflow glue structure for laminated glass, comprising a lower anti-overflow seat 1, a lower PVB film strip 2 is bonded to the upper side of the lower anti-overflow seat 1, a bidirectional screw rod 3 is rotatably connected to the front side of the lower anti-overflow seat 1, the outer sides of the left and right ends of the bidirectional screw rod 3 are both threadedly connected to side anti-overflow seats 4, and the inner side of the side anti-overflow seat 4 is bonded to the side PVB film strip 5;

[0032] The lower PVB film strip 2 and the side PVB film strip 5 are vertically distributed to each other, and the lower ends of the lower PVB film strip 2 and the side PVB film strip 5 fit each other, which can reduce the gap between the lower PVB film strip 2 and the side PVB film strip 5, and seal and enclose the edge of the glass; the side anti-overflow seat 4 is a side "U"-shaped structure, and the lower end of the side anti-overflow seat 4 passes through the lower anti-overflow seat 1 and is slidably connected to the lower anti-overflow seat 1, and the lower anti-overflow seat 1 is a "U"-shaped structure, which can limit the side anti-overflow seat 4 to maintain horizontal movement, so that the side anti-overflow seat 4 adapts to the size of the glass and fits the side edge of the glass;

[0033] Place the lower anti-overflow seat 1 flat in the working area, and place the lower end of the glass on the lower PVB film strip 2 on the upper side of the lower anti-overflow seat 1. At this time, the glass is located between the two groups of pressure rollers 14, so that the lower PVB film strip 2 is tightly fitted with the lower end of the glass to enclose the lower end of the glass. Turn the bidirectional screw 3, which controls the movement of the side anti-overflow seat 4 connected by the outer thread. Since the left and right sections of the bidirectional screw 3 are distributed in opposite directions, the side anti-overflow seat 4 can be driven to move relatively, and the distance between the side anti-overflow seats 4 is gradually shortened, so that the side PVB film strip 5 bonded to the inner side of the side anti-overflow seat 4 gradually fits tightly with the side edge of the glass to enclose the side edge of the glass. Glue injection is performed from the upper side of the glass to prevent glue from overflowing from the other edges of the glass.

[0034] The side walls of the side overflow prevention seat 4 are penetrated by a driving rod 12, and a pressure roller 14 is installed at the end of the driving rod 12. The pressure roller 14 is elastically connected to the side overflow prevention seat 4 through a tension spring 13, and a driving component for adjusting the clamping degree of laminated glass injection curing is provided on the side overflow prevention seat 4; the driving component includes a limiting rod 6 installed on the outside of the side overflow prevention seat 4, and the outside of the limiting rod 6 is slidably connected to a connecting frame 7, and the end of the connecting frame 7 is connected to a moving rod 8, and a bump 9 is installed on the outside of the moving rod 8; the connecting frame 7 is symmetrically arranged about the longitudinal center line of the lower overflow prevention seat 1, and the end of the connecting frame 7 at the left position is connected to an adjusting rod 10, and the end of the connecting frame 7 at the right position is connected to a supporting rod 11, and the end of the adjusting rod 10 penetrates the supporting rod 11, and the adjusting rod 10 and the supporting rod 11 are slidably connected, and the adjusting rod 10 and the support rod 11 are used to realize the synchronous vertical movement of the two groups of connecting frames 7, and avoid affecting the movement of the side overflow prevention seat 4;

[0035] The connecting frame 7 is sleeved on the outer side of the side anti-overflow seat 4. The connecting frame 7 and the limiting rod 6 are fixed by bolts, which can ensure the stable vertical movement of the connecting frame 7 and can be fixed on the limiting rod 6 to prevent it from moving by itself, thereby ensuring the stability of glass clamping; the position of the protrusion 9 and the position of the driving rod 12 are set in a one-to-one correspondence. The protrusion 9 is a trapezoidal structure. The movement of the protrusion 9 can be used to push the driving rod 12 to move, thereby driving the pressure roller 14 to clamp the laminated glass;

[0036] When the side anti-overflow seat 4 moves, the connecting frame 7 moves synchronously, and the adjusting rod 10 slides in the supporting rod 11 to ensure the smooth movement of the side anti-overflow seat 4, and the connecting frame 7 is pressed downward, and the connecting frame 7 slides on the limiting rod 6. The connecting frame 7 controls the moving rod 8 installed at the end to move downward, and the moving rod 8 controls the protrusion 9 connected on the outside to move downward, and the protrusion 9 pushes the driving rod 12 to control the driving rod 12 to drive the pressure roller 14 to move in the direction close to the laminated glass, and the pressure roller 14 stretches the tension spring 13 to store force, so that the pressure roller 14 squeezes the laminated glass, clamps the laminated glass and fixes it to ensure the glue solidification. When the glass is tightly bonded together, the connecting frame 7 and the limit rod 6 are locked together with bolts to stabilize the clamping of the laminated glass. After curing is completed, the bolts fixing the connecting frame 7 and the limit rod 6 can be removed, and the connecting frame 7 can be driven to move up, thereby controlling the moving rod 8 to drive the protrusion 9 to move up, releasing the push on the driving rod 12, and the tension spring 13 is reset to move, and the pressure roller 14 is controlled to move away from the laminated glass. By rotating the two-way screw rod 3 in the opposite direction, the side anti-overflow seats 4 can be controlled to move away from each other, and the laminated glass can be taken out.
