Description

Technical Field

[0001] The invention relates to the technical field of glass processing, in particular to a spray drying machine. Background Art

[0002] Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals as the main raw materials, and a small amount of auxiliary raw materials. The main components are silicon dioxide and other oxides. It is widely used in buildings to block wind and transmit light, and is a mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods.

[0003] In order to meet the use requirements after the glass is produced, such as automobile glass, it is necessary to spray anti-reflection or anti-glare coating after the automobile glass is produced to prevent the ambient light from interfering with the driver and to prevent the reflected light from causing visual fatigue to the driver when driving in strong sunlight or at night. The automobile glass needs to be dried after spraying. However, in the existing device, after drying, the glass is manually removed from the conveyor line under the dryer and then stacked together. Since it is manually placed, it is easy to cause friction between the automobile glasses, which can easily cause scratches on the sprayed surface of the automobile glass, thereby affecting the quality of the automobile glass. In addition, manually removing and stacking the dried automobile glass can easily cause the stacking of the automobile glass to be unsatisfactory and protrude, thereby increasing the risk. As the number of automobile glasses increases, the work intensity of the workers will increase.

Through the setting of the rack 77, it can be When the upper connecting plate 73 moves horizontally, the upper connecting plate 76 meshes with the upper connecting plate 73, thereby driving the driving gear 76 to rotate. By setting the driving gear 76, the upper positive and negative screw rods 74 can be driven to rotate, thereby driving the two longitudinal threaded blocks 75 to move toward or in the opposite direction. The right end of the rack 77 coincides with the center line of the transfer plate 5, and the maximum spacing between the stage 11 and the transfer plate 5 is consistent with the length value of the rack 77. The above setting is to set the moving path of the suction cup 8, so that the suction cup 8 can be accurately placed on the automobile glass, and then the suction cup 8 can be adsorbed to avoid deviation between the suction cup 8 and the automobile glass. The upper guide block 79 is connected to the upper guide rod 78, and the upper cross bar 710 is respectively connected to the longitudinal threaded block 75 and the upper guide rod 78. The upper guide block 79 is connected to the upper guide block 79, and the upper longitudinal thread block 75 can be connected to the upper guide block 79 through the upper cross bar 710. When the longitudinal thread block 75 moves, it can drive the upper guide block 79 to move on the upper guide rod 78 under the action of the upper cross bar 710. The upper hinged telescopic frame 711 is connected to the upper cross bar 710, and the lower cross bar 712 is connected to the upper hinged telescopic frame 711. By controlling the two upper cross bars 710 to move toward or in the opposite direction, the upper hinged telescopic frame 711 can be controlled to be telescoped, so that the upper cross bar 710 can be controlled to be lifted and lowered. The lower guide block 713 is connected to the lower cross bar 712, the lower guide rod 714 is connected to the lower guide block 713, and the lower connecting plate 715 is connected to the lower guide rod 714.

Two guide grooves 717 are symmetrically provided inside the upper connecting plate 73 and the lower connecting plate 715. Through the above arrangement, when the upper hinge telescopic frame 711 is extended, the lower connecting plate 715 can be driven to rise and fall, thereby driving the suction cup 8 to rise and fall, so as to adsorb the automobile glass and drive the automobile glass to move. The upper positive and negative screw rods 74, the upper guide rods 78 and the lower guide rods 714 are all installed inside the guide grooves 717, and the suction cup 8 is installed at the bottom end of the lower connecting plate 715.

The driving gear 101 is connected to the reciprocating screw rod 71. Through the above arrangement, the driving gear 101 can be driven to rotate when the reciprocating screw rod 71 rotates. The driven gear 102 cooperates with the driving gear 101. Through the above arrangement, the driven gear 102 can be driven to rotate. A tooth is provided on the driving gear 101. The diameters of the driving gear 101 and the driven gear 102 are the same. By the above arrangement, the speed setting of the driven gear 102 can be realized. The driving gear 101 rotates one circle, and the driven gear 102 rotates a distance of one tooth. The main transmission belt 103 is connected to the driven gear 102. The rotation of the driven gear 102 can drive the main transmission belt 103 to rotate synchronously. The main bevel gear 104 is connected to the main transmission belt 103. Under the action of the main transmission belt 103, the main bevel gear 104 can be driven to rotate synchronously. The secondary bevel gear 105 cooperates with the main bevel gear 104. By the arrangement of the main bevel gear 104, the secondary bevel gear 105 can be driven to rotate. The secondary transmission belt 106 is connected to the secondary bevel gear 105. The receiving gear 107 is connected to the secondary transmission belt 106. By the above arrangement, the secondary bevel gear 105 can be driven to rotate synchronously. When the wheel 105 rotates, the receiving gear 107 is driven to rotate through the secondary transmission belt 106. The gear ratio of the main bevel gear 104 and the secondary bevel gear 105 is consistent. The above arrangement is to ensure that the main bevel gear 104 and the secondary bevel gear 105 rotate synchronously at the same speed. The main bevel gear 104 and the driven gear 102 are arranged flush with each other up and down, and the secondary bevel gear 105 and the receiving gear 107 are arranged flush with each other left and right. The above arrangement can avoid the deviation between the main bevel gear 104 and the driven gear 102, and the secondary bevel gear 105 and the receiving gear 107. The driven gear 108 cooperates with the receiving gear 107, and the gear ratio of the receiving gear 107 to the driven gear 108 is 1:2. The above arrangement is to allow the receiving gear 107 to rotate with the driven gear 108. The lower forward and reverse screw rod 109 can rotate at twice the speed, and the differential setting can make the lower forward and reverse screw rod 109 rotate at a slower speed. The lower forward and reverse screw rod 109 and the connecting rod 1011 are both installed inside the bottom stacking device 1, and the connecting rod 1011 is also installed in the worktable 11. The bottom stacking device 1 and the worktable 11 are both provided with mounting grooves 1014, and the lower forward and reverse screw rod 109 and the connecting rod 1011 are both installed in the mounting grooves 1014.

The lower hinged telescopic frame 1013 is installed between the connecting blocks 1012. Through the above-mentioned setting, the extension and retraction of the lower hinged telescopic frame 1013 can be realized, thereby driving the worktable 11 to move synchronously.

[0030] Working principle: when in use, the sprayed automobile glass is placed on the conveyor line 2, and the automobile glass follows the conveyor line 2 to the bottom of the baking furnace body 3, and the baking furnace body 3 bakes the automobile glass to achieve drying of the automobile glass. The dried automobile glass follows the conveyor line 2 to the plate discharge elevator 4, and the plate discharge elevator 4 drives the automobile glass to descend to be flush with the transfer plate 5, and then the automobile glass is transported to the transfer plate 5 under the action of the conveying device on the plate discharge elevator 4, and then the servo motor 9 is started. The servo motor 9 can drive the reciprocating screw rod 71 to rotate, and the reciprocating screw rod 71 can drive the upper connecting plate 73 to move toward the direction of the automobile glass through the transverse thread block 72 when rotating, and the upper connecting plate 73 can drive the driving gear 76 to move synchronously when moving, and the driving gear 76 will mesh with the rack 77 when moving, so as to drive the driving gear 76 to rotate, and the driving gear 76 can drive the upper positive When the reverse screw rod 74 rotates, the upper positive and negative screw rod 74 can drive the two longitudinal thread blocks 75 to move towards each other when rotating. When the longitudinal thread block 75 moves, it can drive the upper cross bar 710 to move synchronously, and at the same time, it can drive the upper guide block 79 to slide on the upper guide rod 78. When the upper cross bar 710 moves, it can drive the upper hinge telescopic frame 711 to stretch. When the upper hinge telescopic frame 711 opens the mouth, it can push the lower cross bar 712 downward, and then drive the lower guide block 713 to slide on the lower guide rod 714, so that the suction cup 8 can be driven downward through the lower connecting plate 715. When the driving gear 76 is disengaged from the rack 77, the suction cup 8 just moves to the top of the automobile glass and absorbs the automobile glass. When the cross thread block 72 moves to the end of the reciprocating screw rod 71 and starts to move in the direction of the servo motor 9, the above components start to move in the opposite direction, so as to drive the automobile glass to move.

[0031] When the reciprocating screw rod 71 rotates, it can drive the driven gear 102 to rotate through the driving gear 101, and drive the main bevel gear 104 to rotate under the action of the main transmission belt 103. When the main bevel gear 104 rotates, it can drive the secondary transmission belt 106 to rotate through the secondary bevel gear 105, and drive the receiving gear 107 to rotate through the secondary transmission belt 106. When the receiving gear 107 rotates, it can drive the passive gear 108 to rotate. When the passive gear 108 rotates, it can drive the lower forward and reverse screw rod 109 to rotate. When the lower forward and reverse screw rod 109 rotates, it can drive the connecting thread block 1010 to move in the opposite direction, and then drive the lower hinged telescopic frame 1013 to compress, thereby driving the loading platform 11 to drop the height of a piece of automobile glass, thereby ensuring that the automobile glass can be unloaded while moving horizontally.
