Description

Technical Field

[0001] The present invention relates to the technical field of furniture manufacturing equipment, and in particular to a sliding cabinet door production line. Background Art

[0002] like Figure 1 —2 shows a sliding cabinet door and its cabinet structure. The cabinet door is traditionally hinged with hinges outside the storage space of the cabinet. When opening and closing the cabinet door, it needs to be opened to the front side. In a small area (such as a porch, balcony), a certain amount of space is required. Figure 1 The cabinet door structure is to set up grooves 101 on the upper and lower shelves of the cabinet storage space, and the cabinet door is embedded in the groove 101 and moved in the groove. When in use, the storage space is opened and closed by dragging the cabinet door 102. Generally, the range of the groove 101 is around the entire periphery of the shelf. Figure 1 In the cabinet shown, when the cabinet door is partially slid to the rear, two shelves can be used at the same time.

[0003] Among the existing structures, the bamboo-like appearance and continuous slat structure are favored by the market. Figure 2 As shown, multiple panels 103 are glued side by side on a skin 104 (non-woven fabric with a certain thickness) to realize sliding cabinet doors. In the existing production process, it is necessary to manually lay multiple wood slats (2 meters to 3 meters) flat on a table to form an integral surface material, and then lay a skin slightly larger than the surface material on another table. After that, the two tables are manually sprayed with glue, and then multiple workers turn over the glued skin and apply it to the surface material. In addition, an auxiliary pressing plate is required to push to ensure that the skin is applied flat. This process is time-consuming and labor-intensive and requires the cooperation of multiple workers to complete. It is inefficient, and sometimes too much glue can easily cause edge overflow, thereby affecting the production efficiency and quality of the final cabinet door. For this reason, it is necessary to design equipment that can meet the automated production of sliding cabinet doors. Summary of the Invention

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] like Figure 3-13As shown, the present invention relates to a sliding cabinet door feeding and spraying mechanism, including a cabinet door slat feeding mechanism and a skin bonding mechanism, the cabinet door slat mechanism includes an oblique input platform 10 for inputting wooden strips, and centering guide devices are symmetrically provided on both sides of the oblique input platform 10, and the output end of the input platform 10 has a horizontal gluing conveyor platform 20, and the gluing conveyor belt has a gluing conveyor belt, and the conveying direction of the gluing conveyor belt is located at the output end and a front side baffle 201 is provided.

[0023] The inclined input platform 10 is used to allow the strips of wooden boards to enter the input platform one by one. An input belt 110 is provided in the middle of the input platform. The conveyor belt on the input platform inputs the strips of wooden boards to the gluing conveying platform 20. Centering guide devices are provided on both sides of the input platform. The centering guide devices include guide plates 120 symmetrically fixed on both sides of the input platform. The distance between the two guide plates gradually narrows from the input end to the output end. The guide plates are connected to both sides of the input platform via springs 121.

[0024] To gradually center the strips of sheet material, the input platform 10 is equipped with graduated plates 130 on either side. A retaining plate 140 is nested between these plates. Bolted to the graduated plates, the retaining plate 140 has vertical locking slots for the bolts. The distance between the retaining plate and the upper surface of the input belt 110 is less than the thickness of the two sheets, preventing them from stacking on the input platform 10. Sheets entering the input platform 10 fall onto the gluing conveyor 20 located below the input platform 10.

[0025] The middle part of the gluing conveying platform 20 is provided with a gluing conveyor belt 210, and the conveying direction of the gluing conveyor belt is in the same direction as the input conveyor belt. The output end of the gluing delivery platform 20 is provided with a side panel to prevent the plates from falling. The plates are gradually arranged under the conveyance of the gluing conveyor belt 210, and are gradually brought together to form a panel under the drive of the gluing conveyor belt 210 (the plates at the end of the output direction of the gluing conveyor belt 210 are blocked by the front side baffle 201 and will not fall). When the number of plates is met, the gluing conveyor belt 210 and the input belt 110 both stop working.

[0026] A slat glue spraying device is provided above the gluing conveying platform 20, and the slat glue spraying device includes a support frame 220, and the support frame includes a transverse moving mechanism. The moving end of the transverse moving mechanism is fixed with a lifting mechanism, and the output end of the lifting mechanism is fixed with a glue spraying fixed plate 223, and the glue spraying fixed plate is fixed with a glue nozzle 202. Each glue nozzle is connected to a glue spraying hose, and the glue spraying hose is connected to a pump body (for inputting glue to the surface of the wooden board).

[0027] In this embodiment, the lifting mechanism is a lifting glue spraying cylinder 222, and the lateral moving mechanism is a lateral glue spraying electric cylinder 221. The telescopic end of the lateral glue spraying electric cylinder is fixedly connected to the lifting glue spraying cylinder. The glue spraying fixing plate to which the telescopic end of the lateral glue spraying electric cylinder is fixed has a ring for fixing the glue nozzle 202, and the fixed glue nozzle 202 is clamped on the ring.

[0028] After the gluing conveyor belt 210 and the input belt 110 stop working, the lifting glue spray cylinder 222 drives the glue spray fixed plate 223 to move down close to the plate on the gluing conveyor belt 210, and then the glue nozzle 202 sprays glue onto the upper surface of the panel. The glue is input to the glue nozzle 202 through the glue spray hose by the pump body, and then the horizontal glue spray electric cylinder 221 drives the lifting glue spray cylinder 222 and the glue nozzle 202 to move along the length direction of the panel so that glue is evenly sprayed on the surface of the panel.

[0029] In one embodiment of the present invention, the glue spray fixing plate 223 has a through hole 225 for the glue nozzle to pass through, and a ring 226 is fixed on the glue nozzle. Fixed plates extend from both ends of the ring 226, and the fixed plates are threadedly connected to the glue spray fixing plate. The glue spray fixing plate has a fastening groove 224 for the screw to pass through.

[0030] The fixing piece can be used to adjust the position or quantity of the glue nozzles.

[0031] In order to be able to push the panel that has been glued on the gluing conveyor platform to the subsequent workstation, the gluing conveyor platform is provided with a movable electric cylinder 230 fixed on the frame on one side of the output end, and the movable end of the movable electric cylinder is fixed with a push plate 231 that can be perpendicular to the conveying direction of the gluing conveyor belt.

[0032] The transfer table 30 beside the gluing conveying table is used to move the panel to the transfer table 30 in a flush manner after the panel is glued.

[0033] The skin bonding mechanism includes a transfer table 30 located next to the gluing conveying table, and a release cylinder 401 is provided on the frame above the transfer table 30 for winding the skin 104. The front side of the transfer table is also provided with a skin pressure roller 402, and a conveying roller 403 for guiding the skin 104 is provided between the skin pressure roller 402 and the release cylinder. There is also a gluing roller 410 located on the lower surface of the skin between the skin pressure roller 402 and the release cylinder 401. The upper part of the gluing roller 410 is in contact with the lower surface of the skin 104, and a glue groove 430 is provided at the lower part. The upper part of the gluing roller 410 is also provided with a top roller 420 paired with the gluing roller for clamping the skin so that the skin is in full contact with the gluing roller. There are multiple skin pressure rollers 402, and the upper surface of the transfer table 30 is provided with multiple conveying rollers 310 corresponding to the lower part of the skin pressure roller 402.

[0034] The release cylinder 401, the skin pressing roller 402, the conveying roller 403, the gluing roller 410 and the top roller 420 are hinged to the frame.

[0035] In this embodiment, after the push plate 240 pushes the panel to the conveying roller 310, the conveying roller 310 rotates under the drive of the motor, so that the skin pressing roller 402 and the conveying roller 310, the conveying roller 310 and the corresponding skin pressing roller 402 above jointly press the glued panel and the skin 104 together and push them to the front side. The skin 104 is pulled by the conveying roller 310 and the skin pressing roller 402 and gradually released from the release cylinder 401. During the release process, glue is applied to the inner side of the skin 104 through the cooperation of the top roller 420 and the gluing roller 410.

[0036] The lower part of the gluing roller 410 is immersed in the glue in the glue tank 430. When the gluing roller 410 and the top roller 420 clamp the skin and the skin moves, the gluing roller continues to roll and applies glue to the lower surface of the skin.

[0037] In one embodiment of the present invention, there are multiple skin pressing rollers, and each of the conveying rollers is driven by a motor to rotate in the same direction to drive the plate to move toward the receiving table. There are also multiple conveying rollers between the skin pressing rollers and the release cylinder.

[0038] A heating platform 50 for drying glue is also provided in the output direction of the transfer table 30. A heating cover 510 is provided above the heating platform. A hot air outlet 520 facing the heating platform is provided in the heating cover. The hot air outlet is connected to a hot air blower 530. The heating platform has a heating conveyor belt 540. The output end of the heating platform has a material receiving platform 60, and the material receiving platform 60 is at the same height as the heating platform surface.

[0039] The conveying roller 310 and the skin pressing roller 402 are arranged in pairs to press the glued panel and the skin 104 together and output them to the heating table 50. The heating cover 510 on the heating table is provided with a hot air outlet. The hot air from the hot air blower is transported to the hot air outlet through the pipeline by the pump body, and the hot air is blown toward the surface of the panel and the skin to quickly dry the glue on the panel and the skin. Generally, the glue used is sprayed evenly and is in the heating cover 510 area. The glue can be dried in 10-20 seconds. In addition, after drying, the upper and lower cabinet doors can be prevented from sticking together during the later stacking process.

[0040] In one embodiment of the present invention, the glue tank 430 is provided with an electric heating wire for heating the glue to prevent the glue from solidifying.

[0041] In one embodiment of the present invention, the discharge port of the heating table 50 is provided with an auxiliary pressure roller 520, and the two ends of the auxiliary pressure roller are hingedly connected to a cross bar 530 through bearings. The end of the cross bar is sleeved on a screw 531, and the cross bar 530 and the heating table 50 are connected by a compression spring 540. The upper end of the screw 531 is threadedly connected with a locking nut 550.

[0042] In this embodiment, the locking nut 550 is used to adjust the pre-tightening degree of the compression spring 540. When the bonded plate and skin pass through the auxiliary pressing roller 520, the skin 104 can be rolled and flattened by the auxiliary pressing roller 520.

[0043] In order to facilitate subsequent stacking and sorting, in one embodiment of the present invention, a cutting device is provided between the discharge end of the heating table 50 and the receiving table 60, and the cutting device includes a cutting bracket 70 fixed above the heating table, and the top of the cutting bracket is provided with a cutting horizontal cylinder 710, and the telescopic end of the cutting horizontal cylinder 710 is fixed with a cutting lifting cylinder 720, and the telescopic end of the cutting lifting cylinder 720 is fixed with a cutting motor 730, and the output shaft of the cutting motor is fixed with a circular saw 740, and a gap 501 is provided between the receiving table and the heating table surface for the circular saw to move downward.

[0044] To ensure the sheet remains stationary and stable during the cutting process of the circular saw 740, a downward pressure cylinder 610 is fixed to the frame above the receiving platform 60. The telescopic end of the downward pressure cylinder faces the receiving platform and is fixed with a pressure plate 620. During cutting, the downward pressure cylinder 610 drives the pressure plate 620 downward to press the sheet to which the skin 104 has been bonded. The cutting lift cylinder 720 then drives the cutting motor 730 and the circular saw 740 to move to the side of the panel. The cutting cross cylinder 710 drives the cutting lift cylinder 720, the cutting motor 730, and the circular saw 740 to move along the gap 501, thereby cutting the sheet. Subsequent sheets continue to enter, and the cut sheets are pushed forward and then stacked and transported by suction cups or manually.
