Description

An automatic edge banding machine for gypsum board Technical Field

[0001] This invention belongs to the field of gypsum board processing technology, and in particular relates to an automatic edge banding machine for gypsum boards. Background Technology

[0002] Gypsum board sealing refers to attaching a layer of protective paper to the cut edges of gypsum board after processing, thereby preventing damage to the gypsum board during transportation and improving its quality.

[0003] When sealing the edges of gypsum board, the gypsum board is stacked on the material frame, and the material frame is manually pushed to the conveyor belt of the edge sealing machine. The gypsum board in the material frame is placed on the conveyor belt one by one, and then the edge sealing mechanism on the edge sealing machine pastes the protective paper onto the gypsum board, thus completing the edge sealing of the gypsum board.

[0004] Existing edge banding machines require manual feeding of gypsum boards onto the conveyor belt. Since the gypsum boards have a certain weight, workers have to carry the gypsum boards from the material box onto the conveyor belt for a long time, which increases the labor intensity of the workers and can easily cause back injuries to the workers. Summary of the Invention

The driving component then drives the guide slider to move to the left on the guide groove. The guide slider drives the pushing block to move to the left, pushing the pushing block... When the inclined surface contacts the gypsum board, the push block retracts into the guide slider. As the push block moves to the left, it no longer contacts the gypsum board. At this time, the first transmission component drives the rack to move to the left via the drive component. The rack drives the gear to rotate in the opposite direction, and the gear drives the rotating sleeve to rotate in the opposite direction. The second transmission component drives the drive screw to rotate via the reverse rotation of the rotating sleeve. The drive screw drives the placement platform upwards via threaded transmission. As the push block moves to the left and resets, the placement platform moves upwards by the thickness of a gypsum board, thus achieving automatic gypsum board feeding. This avoids the need for manual feeding of the conveyor belt during gypsum board edge sealing, saving manpower and reducing worker fatigue. After the gypsum board supply to the placement platform is complete, the handwheel is turned. The handwheel drives the drive screw to rotate, and the drive screw drives the placement platform downwards and resets via threaded transmission. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] As shown in Figures 1-4, an automatic gypsum board edge banding machine according to an embodiment of the present invention includes a movable base plate 101, the bottom of which is equipped with rollers with self-locking devices, and further includes:

[0032] Drive screw 107, guide slider 109, push block 110, rack 112, rotating sleeve 113 and elastic connection assembly 2;

[0033] The top of the movable base plate 101 is equipped with four guide columns 102, and a placement platform 103 is slidably connected to the guide columns 102. A first fixing plate 105 and a second fixing plate 106 are fixed on the guide columns 102.

[0034] The movable base plate 101 is fixed with baffles 104 around the placement platform 103. The drive screw 107 is rotatably connected to the movable base plate 101 and threadedly connected to the placement platform 103. A handwheel 115 is installed at the end of the drive screw 107.

[0035] The first fixed plate 105 is provided with a guide groove 108, the guide slider 109 is slidably connected to the guide groove 108, the push block 110 is elastically extended and retracted on the guide slider 109 through the elastic connection component 2, and the lower end of the push block 110 is provided with an inclined surface 111 for contacting the gypsum board.

[0036] A drive assembly 3 is disposed on the second fixed plate 106. The drive assembly 3 is used to drive the guide slider 109 to reciprocate on the guide groove 108.

[0037] The rack 112 is slidably connected to the first fixed plate 105, the rotating sleeve 113 is rotatably connected to the bottom of the first fixed plate 105, and the drive screw 107 passes through the rotating sleeve 113. The rotating sleeve 113 is equipped with a gear 114 that meshes with the rack 112.

[0038] The first transmission component 5 is mounted on the drive component 3. The first transmission component 5 drives the rack 112 to move back and forth in the left and right directions through the drive component 3.

[0039] The second transmission component 7 is mounted on the rotating sleeve 113. The second transmission component 7 drives the drive screw 107 to rotate intermittently by the reciprocating rotation of the rotating sleeve 113.

[0040] In this embodiment of the invention, during use, the plasterboard is placed on the placement platform 103, and then the movable base plate 101 is moved to the conveyor belt of the edge banding machine. The elastic connecting component 2 pushes the pushing block 110 downward. When the pushing block 110 is located to the left of the plasterboard, the lower end of the pushing block 110 is lower than the upper end of the uppermost plasterboard. The driving component 3 drives the guide slider 109 to move to the right on the guide groove 108. The guide slider 109 drives the pushing block 110 to move to the right, and the pushing block 110 pushes the uppermost plasterboard to the right. The plasterboard is pushed onto the conveyor belt, which then transports it. Simultaneously, the first transmission assembly 5 drives the rack 112 to move to the right via the drive assembly 3.

When the inclined plane 111 contacts the plasterboard, the pushing block 110 retracts into the guide slider 109, and thus the pushing block 110 moves to the left without contacting the plasterboard. At this time, the first transmission assembly 5 drives the rack 112 to move to the left through the drive assembly 3. The rack 112 drives the gear 114 to rotate in the opposite direction, and the gear 114 drives the rotating sleeve 113 to rotate in the opposite direction. The second transmission assembly 7 drives the drive screw 107 to rotate through the reverse rotation of the rotating sleeve 113. The drive screw 107 drives the placement platform 103 to rotate through the threaded transmission. The platform moves upward, and when the push block 110 moves to the left and resets, it drives the placement platform 103 to move upward by the thickness of a gypsum board, thereby realizing automatic feeding of gypsum board. This avoids the problem of manually feeding the conveyor belt when sealing the edges of the gypsum board, thus saving manpower and reducing the labor intensity of workers. After the gypsum board on the placement platform 103 is fed, the handwheel 115 is turned, and the handwheel 115 drives the drive screw 107 to rotate. The drive screw 107 drives the placement platform 103 to move downward and reset through the threaded transmission.
