Description

Technical Field

[0001] The invention relates to the technical field of hollow glass manufacturing, in particular to a butyl rubber coating machine. Background Art

[0002] At present, building energy consumption has reached 27.6% of social energy consumption, and 50% of building energy consumption is related to doors and windows. Hollow glass has good heat insulation and sound insulation effects. Doors and windows made of hollow glass are widely used in technical buildings.

[0003] Insulating glass is a high-efficiency sound-proof and heat-insulating glass made of two (or three) pieces of glass, using a high-strength and high-airtightness composite adhesive to bond the glass sheets to an aluminum alloy frame containing a desiccant. Insulating glass has many properties that are superior to ordinary double-layer glass, and therefore has been recognized by countries around the world. Insulating glass is a glass product that separates two or more pieces of glass evenly with effective support and bonds and seals them around the edges to form a dry gas space between the glass layers. Its main materials are glass, warm edge spacers, corner plugs, butyl rubber, polysulfide glue and desiccant.

[0004] The aluminum alloy frame of the insulating glass is bonded with butyl rubber, and the butyl rubber needs to be applied to the joints of the frames. The existing butyl rubber coating machine is not convenient for positioning the aluminum alloy frame of the insulating glass when coating the aluminum alloy frame of the insulating glass, which causes the aluminum alloy frame of the insulating glass to easily shift during coating, affecting the coating effect. Therefore, we propose a butyl rubber coating machine. Summary of the invention

[0005] The invention aims to provide a butyl rubber coating machine, which has the effect of facilitating the positioning of the aluminum alloy frame of the insulating glass.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a butyl rubber coating machine, including a base, a cabin installed in the base, a transmission component installed on the base, a connecting platform installed on the base and located on both sides of the transmission component, a U-shaped groove provided on the connecting platform, a glue coating head sliding in the U-shaped groove, and a glue discharge component installed in the cabin and providing butyl rubber to the glue coating head, two pressing components are installed on the connecting platform on the rear side, and an adjustment component for changing the distance between the two glue coating heads is also provided on the connecting platform, a control system is also installed on the base, a photosensor and a width measurer are also installed on the base, the photosensor and the width measurer are electrically connected to the control system, and the control system is electrically connected to the pressing component and the adjustment component.

[0007] By adopting the above technical scheme, one side of the aluminum alloy frame to be coated with glue is placed on the transmission component, and the worker holds the aluminum alloy frame with his hand to prevent it from tipping over. The aluminum alloy frame moves along the direction of the transmission component and passes through the photosensitive sensor first. The photosensitive sensor transmits the detected signal to the control system. The control system starts the width measuring device to measure the span of the aluminum alloy frame to be coated with glue. Then the aluminum alloy frame continues to pass through the width measuring device. The control system controls the adjusting component to change the distance between the two gluing heads. Pressing components are set on both sides of the gluing head to press the two sides of the aluminum alloy frame to be coated with glue. The gluing head applies glue, thereby realizing automatic positioning of the aluminum alloy frame during gluing, avoiding the displacement of the aluminum alloy frame during gluing, and achieving better gluing effect.

[0008] The present invention is further configured as follows: the transmission component includes a mounting frame installed on the base, two rotating wheels rotatably connected to the inner side of the mounting frame, a transmission belt transmission-connected to the two rotating wheels, and a transmission motor installed on the mounting frame and driving one of the rotating wheels to rotate.

[0009] By adopting the above technical solution, the transmission motor starts to drive one of the rotating wheels to rotate. When one of the rotating wheels rotates, it drives the other rotating wheel to rotate through the transmission belt, so that the transmission belt rotates as a whole to transmit and apply glue to the aluminum alloy frame to be coated with glue. No manual feeding is required, which reduces the workload of operators.

[0010] The present invention is further configured as follows: the upper surface of the conveyor belt is on the same horizontal line as the upper surface of the mounting frame.

[0011] By adopting the above technical solution, the pressing assembly will not be blocked by the mounting frame when pressing the two sides of the aluminum alloy frame where glue is required, ensuring that the pressing assembly can be pressed on the inner wall of the aluminum alloy frame.

[0012] The present invention is further configured as follows: the glue discharging assembly includes a glue cylinder installed in the cabin, a heating cylinder sleeved outside the glue cylinder, a glue pump installed on the heating cylinder, a glue discharging hose connecting the glue pump and the glue coating head, and a rubber hose connecting the glue pump and the glue cylinder.

[0013] By adopting the above technical solution, butyl rubber is stored in the glue cylinder, and the heating cylinder heats the butyl rubber in the glue cylinder to ensure that the butyl rubber has good fluidity. The glue pump is started to extract the butyl rubber in the glue cylinder using a rubber hose, and then it is transported to the glue coating head through a glue outlet hose to coat the aluminum alloy frame with glue.

[0014] The present invention is further configured as follows: the pressing assembly includes a deflection support rod hinged on the connecting platform, a pressing rod hinged to the other side of the deflection support rod, a pressing barrel rotatably connected to the outside of the pressing rod, and a cylinder 1 installed on the connecting platform, the output end of the cylinder 1 is fixedly connected to the pressing barrel, and the control system controls the cylinder 1 to extend and retract.

[0015] By adopting the above technical scheme, when the cylinder makes an extending movement, the deflection support rod rotates from back to front and moves from an inclined state to a vertical state, so that the pressure rod drives the pressing barrel to press the two sides of the aluminum alloy frame on the conveyor belt from top to bottom where glue is required, and then the glue applying head applies glue, thereby realizing automatic positioning of the aluminum alloy frame during gluing, avoiding the displacement of the aluminum alloy frame during gluing, and achieving a better gluing effect. After the previous aluminum alloy frame is glued, when the cylinder makes a contracting movement, the deflection support rod rotates from front to back and moves from a vertical state to an inclined state, so that the pressure rod drives the pressing barrel to move up and separate from the conveyor belt.

[0016] The present invention is further configured as follows: the adjustment component includes a push rod hinged on the glue coating head, a cross bar hinged to the other side of the push rod, a through hole opened on the base, a swing rod rotatably connected in the through hole and hinged to the other side of the cross bar, and a cylinder 2 installed on the base, the output end of the cylinder 2 is fixedly connected to the swing rod, and the control system controls the cylinder 2 to extend and retract.

[0017] By adopting the above technical solution, when the second cylinder extends and retracts, the swing rod deflects left and right in the through hole, thereby pushing the cross bar to swing left and right. The left and right swing of the cross bar causes the push rod to drive the gluing head to slide back and forth in the U-shaped groove, changing the distance between the two gluing heads. This is suitable for gluing aluminum alloy frames of different widths.

[0018] The present invention is further configured as follows: the glue coating head is slidably connected to the U-shaped groove via a slider, and the inner wall of the U-shaped groove is designed to be smooth.

[0019] By adopting the above technical solution, the glue coating head can move more smoothly in the U-shaped groove.

[0020] The present invention is further configured as follows: a fixed limiting assembly is installed on the mounting frame, and the fixed limiting assembly includes a fixed baffle installed on the mounting frame, and an L-shaped groove and a glue outlet hole provided on the fixed baffle, and the glue outlet hole is connected to the inner wall of the L-shaped groove for the front glue coating head to pass through the glue outlet hole.

[0021] By adopting the above technical scheme, the aluminum alloy frame is supported manually when being transported on the conveyor belt, a fixed baffle is set on the side without the pressing component to block one side of the aluminum alloy frame, and then a glue outlet hole is set to facilitate the fixed baffle to assist in fixing the aluminum alloy frame while transporting it, and the aluminum alloy frame can also be coated with glue. The set L-shaped groove can prevent the glue coating of the aluminum alloy from contacting the fixed baffle and rubbing off the butyl glue on the surface of the aluminum alloy frame, thereby ensuring a good gluing effect.

[0022] The present invention is further configured as follows: an adjustable limit assembly is installed on the pressure rod, and the adjustable limit assembly includes a transverse groove opened on the pressure rod, a guide rail installed in the transverse groove, a fixed stop block slidably connected to the guide rail, a plurality of screw holes opened on the guide rail, and bolts threadedly connecting the fixed stop block and the screw holes.

[0023] By adopting the above technical solution, when the pressure rod drives the pressing barrel to move downward and press the inner wall of the aluminum alloy frame, the fixed stop block moves downward with the pressure rod at the same time and fits the surface of the conveyor belt, so that the fixed stop block can cooperate with the fixed baffle to limit the aluminum alloy frame from the other side to avoid deviation during glue coating. The fixed stop block can be connected to the screw holes at different positions on the guide rail by bolts, thereby changing the distance from the fixed stop block to the pressing barrel, so that the fixed stop block can limit the aluminum alloy frames of different widths, which is more applicable.

[0024] The present invention is further configured as follows: the distance from the bottom of the fixed stopper to the center of the pressing rod is greater than the distance from the pressing barrel to the center of the pressing rod, and the difference between the two distances is the thickness of the inner wall of the aluminum alloy frame.

[0025] By adopting the above technical solution, when the pressing barrel fits against the inner wall of the aluminum alloy frame and presses it, the fixed stopper is flush with the surface of the conveyor belt, limiting the aluminum alloy frame from the side, which has a better limiting effect and avoids deviation during glue coating.

[0026] The beneficial effects of the present invention are:

[0027] 1. When the cylinder extends, the deflection support rod rotates from back to front and moves from an inclined state to a vertical state, so that the pressure rod drives the pressing barrel to press the two sides of the aluminum alloy frame on the conveyor belt from top to bottom where glue is required, and then the glue coating head applies glue, thereby realizing automatic positioning of the aluminum alloy frame during glue coating, avoiding the aluminum alloy frame from shifting during glue coating, and achieving a better glue coating effect.

[0028] 2. When the second cylinder extends and contracts, the swing rod deflects left and right in the through hole, thereby pushing the cross bar to swing left and right. The left and right swing of the cross bar causes the push rod to drive the gluing head to slide back and forth in the U-shaped groove, changing the distance between the two gluing heads. This is suitable for gluing aluminum alloy frames of different widths.

[0029] 3. The aluminum alloy frame is supported manually when being transported on the conveyor belt. A fixed baffle is set on the side without the pressing component to block one side of the aluminum alloy frame. Then, a glue outlet hole is set to facilitate the fixed baffle to assist in fixing the aluminum alloy frame while transporting it. The aluminum alloy frame can also be coated with glue. The set L-shaped groove can prevent the glue coating of the aluminum alloy from contacting the fixed baffle and rubbing off the butyl glue on the surface of the aluminum alloy frame, thereby ensuring a good gluing effect.

[0030] 4. When the pressure rod drives the pressing barrel to move downward and press the inner wall of the aluminum alloy frame, the fixed block moves downward with the pressure rod at the same time to fit the surface of the conveyor belt, so that the fixed block can cooperate with the fixed baffle to limit the aluminum alloy frame from the other side to avoid deviation during glue coating. The fixed block can be connected to the screw holes at different positions on the guide rail through bolts, thereby changing the distance from the fixed block to the pressing barrel, so that the fixed block can limit the aluminum alloy frames of different widths, which is more applicable.

[0038] See also Figure 1-4 The present invention provides a butyl rubber coating machine, comprising a base 1, a cabin 2 installed in the base 1, a transmission component 3 installed on the base 1, a connecting platform 4 installed on the base 1 and located on both sides of the transmission component 3, a U-shaped groove 5 provided on the connecting platform 4, a glue coating head 6 sliding in the U-shaped groove 5, and a glue discharging component 7 installed in the cabin 2 and providing butyl rubber to the glue coating head 6, two pressing components 8 are installed on the rear side of the connecting platform 4, and the connecting platform 4 is also provided with an adjusting component 9 for changing the distance between the two glue coating heads 6, a control system 10 for controlling cylinder 1 84 and cylinder 2 95 is also installed on the base 1, and a photosensor 11 and a width measuring device 12 are also installed on the base 1, and the photosensor 11 and the width measuring device 12 are electrically connected to the control system 10, and the control system 10 is electrically connected to the pressing component 8 and the adjusting component 9.

[0039] The aluminum alloy frame to be coated with glue is placed on one side of the transmission component 3, and the worker holds the aluminum alloy frame with his hand to prevent it from tipping over. The aluminum alloy frame moves along the direction of the transmission component 3 and passes through the photosensitive sensor 11 first. The photosensitive sensor 11 transmits the detected signal to the control system 10. The control system 10 starts the width measuring device 12 to measure the span of the aluminum alloy frame to be coated with glue, and then the aluminum alloy frame continues to pass through the width measuring device 12. The control system 10 controls the adjustment component 9 to change the distance between the two glue coating heads 6. Pressing components 8 are set on both sides of the glue coating head 6 to press the two sides of the aluminum alloy frame to be coated with glue. The glue coating head 6 applies glue, thereby realizing automatic positioning of the aluminum alloy frame during gluing, avoiding the aluminum alloy frame from shifting during gluing, and achieving a better gluing effect.

[0040] The transmission assembly 3 includes a mounting frame 31 installed on the base 1, two rotating wheels 32 rotatably connected to the inner side of the mounting frame 31, a transmission belt 33 transmission-connected to the two rotating wheels 32, and a transmission motor 34 installed on the mounting frame 31 and driving one of the rotating wheels 32 to rotate. When the transmission motor 34 is started, it drives one of the rotating wheels 32 to rotate. When one of the rotating wheels 32 rotates, the other rotating wheel 32 is driven to rotate through the transmission belt 33, so that the transmission belt 33 rotates as a whole to transmit and apply glue to the aluminum alloy frame to be coated with glue, without the need for manual feeding, thereby reducing the work intensity of the operators.

[0041] The upper surface of the conveyor belt 33 is on the same horizontal line as the upper surface of the mounting frame 31, so that the pressing assembly 8 will not be blocked by the mounting frame 31 when pressing the two sides of the aluminum alloy frame where glue is required, ensuring that the pressing assembly 8 can be pressed on the inner wall of the aluminum alloy frame.

[0042] The glue discharging assembly 7 includes a glue cylinder 71 installed in the cabin 2, a heating cylinder 72 sleeved on the outside of the glue cylinder 71, a glue pump 73 installed on the heating cylinder 72, a glue discharging hose 74 connecting the glue pump 73 and the glue coating head 6, and a rubber hose 75 connecting the glue pump 73 and the glue cylinder 71. Butyl rubber is stored in the glue cylinder 71. The heating cylinder 72 heats the butyl rubber in the glue cylinder 71 to ensure that the butyl rubber has good fluidity. The glue pump 73 is started to extract the butyl rubber in the glue cylinder 71 using the rubber hose 75, and then transports it to the glue coating head 6 through the glue discharging hose 74 to coat the aluminum alloy frame with glue.

[0043] The pressing assembly 8 includes a deflection support rod 81 hinged on the connecting platform 4, a pressing rod 82 hinged to the other side of the deflection support rod 81, a pressing barrel 83 rotatably connected to the outside of the pressing rod 82, and a cylinder 84 installed on the connecting platform 4. The output end of the cylinder 84 is fixedly connected to the pressing barrel 83. The control system 10 controls the cylinder 84 to extend and retract. When the cylinder 84 extends, the deflection support rod 81 rotates from the back to the front and moves from the inclined state to the vertical state. The straight state allows the pressure rod 82 to drive the pressure cylinder 83 to press the two sides of the aluminum alloy frame on the conveyor belt 33 where glue is required, and then the glue coating head 6 applies glue, thereby realizing automatic positioning of the aluminum alloy frame during gluing, avoiding the aluminum alloy frame from shifting during gluing, and achieving better gluing effect. After the previous aluminum alloy frame is glued, when the cylinder 84 performs a contraction movement, the deflection support rod 81 rotates from front to back and moves from a vertical state to an inclined state, so that the pressure rod 82 drives the pressure cylinder 83 to move up and separate from the conveyor belt 33.

[0044] The adjusting assembly 9 includes a push rod 91 hinged on the gluing head 6, a cross bar 92 hinged to the other side of the push rod 91, a through hole 93 provided on the base 1, a swing rod 94 rotatably connected in the through hole 93 and hinged to the other side of the cross bar 92, and a cylinder 2 95 installed on the base 1, wherein the output end of the cylinder 2 95 is fixedly connected to the swing rod 94, and the control system 10 controls the cylinder 2 95 to extend and retract. When the cylinder 2 95 extends and retracts, the swing rod 94 deflects left and right in the through hole 93, thereby pushing the cross bar 92 to swing left and right. The swing of the cross bar 92 left and right enables the push rod 91 to drive the gluing head 6 to slide back and forth in the U-shaped groove 5, thereby changing the distance between the two gluing heads 6, and is suitable for gluing aluminum alloy frames of different widths.

[0045] The glue coating head 6 is slidably connected to the U-shaped groove 5 via a slider, and the inner wall of the U-shaped groove 5 is designed to be smooth, so that the glue coating head 6 can move more smoothly in the U-shaped groove 5.

[0046] A fixed limiting assembly 13 is installed on the mounting frame 31, and the fixed limiting assembly 13 includes a fixed baffle 131 installed on the mounting frame 31, and an L-shaped groove 133 and a glue outlet hole 132 provided on the fixed baffle 131. The glue outlet hole 132 is communicated with the inner wall of the L-shaped groove 133, so that the front glue coating head 6 can pass through the glue outlet hole 132. When the aluminum alloy frame is transported on the conveyor belt 33, it is supported manually. A fixed baffle 131 is provided on the side without the pressing assembly 8 to block one side of the aluminum alloy frame, and then the glue outlet hole 132 is provided to facilitate the fixed baffle 131 to assist in fixing the aluminum alloy frame while transporting it, and to coat the aluminum alloy frame with glue. The L-shaped groove 133 can prevent the glue coating of the aluminum alloy from contacting the fixed baffle 131, rubbing off the butyl glue on the surface of the aluminum alloy frame, and ensure a good gluing effect.

[0047] The pressure rod 82 is provided with an adjustable stopper assembly 14, which includes a transverse groove 141 provided on the pressure rod 82, a guide rail 142 provided in the transverse groove 141, a fixed stopper 143 slidably connected to the guide rail 142, a plurality of screw holes 144 provided on the guide rail 142, and a bolt 145 threadedly connecting the fixed stopper 143 and the screw holes 144. When the pressure rod 82 drives the pressure barrel 83 to move downward and press the inner wall of the aluminum alloy frame, The fixed block 143 moves down with the pressure rod 82 and fits the surface of the conveyor belt 33, so that the fixed block 143 can cooperate with the fixed baffle 131 from the other side to limit the aluminum alloy frame to avoid deviation during glue coating. The fixed block 143 can be connected to the screw holes 144 at different positions on the guide rail 142 through bolts 145, thereby changing the distance from the fixed block 143 to the pressure barrel 83, so that the fixed block 143 can limit the aluminum alloy frames of different widths, which is more applicable.

[0048] The distance from the bottom of the fixed stopper 143 to the center of the pressure rod 82 is greater than the distance from the pressure cylinder 83 to the center of the pressure rod 82. The difference between the two distances is the thickness of the inner wall of the aluminum alloy frame. When the pressure cylinder 83 fits the inner wall of the aluminum alloy frame to press it, the fixed stopper 143 is flush with the surface of the conveyor belt 33, limiting the aluminum alloy frame from the side, which has a better limiting effect and avoids deviation during glue coating.
