It should be noted that the embodiments and features of the embodiments of the present invention may be combined with one another unless there is a conflict.

[0032] like Figure 1 、 Figure 2 As shown, an automatic door skin cutting device includes six material warehouses 1, six conveying mechanisms 2 corresponding to the six material warehouses 1, and a cutting mechanism (not shown in the figure). The specifications of the door skins placed in the six material warehouses 1 are different, that is, one specification of door skins is placed in one material warehouse 1.

[0033] The conveying mechanism 2 in this embodiment has its own power and can directly drive the door skin to move.

[0034] Specifically, each material storage 1 includes a support platform 3 for placing door skins and a frame 4 mounted above the support platform 3. The height of the support platform 3 is lower than that of the conveying mechanism 2, so that more door skins can be placed on the support platform 3. The frame 4 is equipped with a movable gripper 16 for grabbing the door skins on the support platform 3. The gripper 16 moves in a left-right direction, and the movable direction of the gripper 16 is consistent with the conveying direction of the conveying mechanism 2. The movable gripper 16 is used to transfer the door skins to the conveying mechanism 2, and the conveying mechanism 2 is used to convey the door skins to the cutting mechanism.

[0035] Two rotating arms 11 are rotatably assembled on one side of the frame 4 close to the conveying mechanism 2. One end of the two rotating arms 11 is rotatably assembled with a guide roller 13. The other end of the two rotating arms 11 is hinged with a linear drive member 12. The fixed end of the linear drive member 12 is hinged on the frame 4. The telescopic end of the linear drive member 12 drives the rotating arm 11 to rotate so that the guide roller 13 revolves. The revolving guide roller 13 is used to press the door skin moving with the gripper 16.

[0036] The support platform 3 in this embodiment has a plurality of rotatable rollers 18 , which makes it convenient for the user to push the door skin onto the support platform 3 .

[0037] In other embodiments, the height of the roller 18 can be raised and lowered by a lifting drive member, thereby changing the height of the roller 18. When the number of door skins on the support platform 3 decreases, the roller 18 is raised to facilitate the transportation of the door skins to the conveying mechanism 2. The roller 18 is gradually raised to the same height as the drum 8.

[0038] The guide roller 13 in this embodiment has no self-powered function and rotates passively.

[0039] In other embodiments, the guide roller 13 is self-powered, and when the guide roller 13 presses against the door skin, the guide roller 13 will assist in driving the door skin to move.

[0040] The user only needs to place the door skin of the corresponding specification on the support platform 3, and the rest of the operations are left to the device to complete the cutting of the door skin; the gripper 16 grabs the door skin and moves the door skin to the conveying mechanism 2, and the conveying mechanism 2 conveys the door skin to move, and at the same time the linear drive member 12 guides the roller 13, allowing the guide roller 13 to press the door skin to prevent its front end from being tilted too high. This device avoids the user from directly pushing the door skin to the cutting device, reduces the danger of the user, avoids the user's mistakes, and saves door skin materials.

[0041] Specifically, if Figure 2 、 Figure 3 、 Figure 5 As shown, the frame 4 has a mounting arm 10 extending toward the conveying mechanism 2. The middle position of the two rotating arms 11 is rotatably assembled on the mounting arm 10 on the corresponding side via a rotating shaft. One end of the two rotating arms 11 is rotatably assembled with a guide roller 13. The other end of the two rotating arms 11 is provided with a connecting rod 14. The fixed end of the linear drive member 12 is hinged to the frame 4, and the telescopic end of the linear drive member 12 is hinged to the connecting rod 14. The linear drive member 12 drives the connecting rod 14 to revolve around the rotating shaft, and at the same time, causes the guide roller 13 to revolve around the rotating shaft. By driving the connecting rod 14 to move through the linear drive member 12, the guide roller 13 can be pressed downward against the door skin to prevent one end of the door skin from tilting too high and affecting the transportation of the door skin.

[0042] Specifically, an auxiliary roller 15 is provided on the side of the frame 4 close to the conveyor mechanism 2. The height of the auxiliary roller 15 is lower than that of the conveyor mechanism 2. The auxiliary roller 15 is self-powered and can rotate autonomously. When the gripper 16 grabs the door skin and places it on the conveyor mechanism 2, the auxiliary roller 15 is first contacted. At the same time, the guide roller 13 presses against the door skin to prevent it from tilting too high. Then, the door skin is moved onto the conveyor mechanism 2 under the action of the auxiliary roller 15.

[0043] Specifically, a linear slide 5 is provided on the frame 4, and a gripper 16 is movably mounted on the linear slide 5 in the left-right direction, so that the linear slide 5 drives the gripper 16 to move along the conveying direction of the conveying mechanism 2. The gripper 16 in this embodiment includes a suction cup 21, a mounting part 20, and an up-and-down lifting part 19 movably mounted on the linear slide 5, the up-and-down lifting part 19 is connected to the mounting part 20, and the mounting part 20 is connected to the suction cup 21 for sucking the door skin through a universal joint. The linear slide 5 drives the gripper 16 to move, thereby driving the door skin grabbed by the gripper 16 to move toward the direction of the conveying mechanism 2; the universal joint enables the suction cup 21 to be suitable for a variety of door skin placement angles. Even if the door skin is tilted upward, the suction cup 21 can adaptively tilt, thereby stably sucking the door skin.

[0044] Specifically, if Figure 4 、 Figure 6 As shown, each conveying mechanism 2 includes a bracket 6 and a plurality of rollers 8 rotatably mounted on the bracket 6 and arranged at intervals, and the rollers 8 convey the door skin in the left and right directions. Figure 7 、 Figure 8 As shown, the height of the roller 8 is higher than that of the auxiliary roller 15, with a height difference H. The bracket 6 is provided with a plurality of belt assemblies 9 arranged at intervals and capable of being raised and lowered in the up and down directions. Each belt assembly 9 is located between two adjacent rollers 8. The belt assembly 9 is used to drive the door skin to move. The conveying direction of the belt assembly 9 is perpendicular to the conveying direction of the roller 8, that is, the belt assembly 9 can convey the door skin in the front and back directions. Under normal conditions, the height of the belt assembly 9 is lower than that of the roller 8. The roller 8 first conveys the door skin. After reaching the set position, the belt assembly 9 rises, thereby lifting the door skin and separating the door skin from the roller 8. Then the belt assembly 9 conveys the door skin to move.

[0045] The belt assembly 9 in this embodiment is self-powered and can directly drive the door skin to move.

[0046] The bracket 6 is provided with an upper and lower raising member 17, which is connected to multiple belt assemblies 9 to drive them to move in the up and down direction. Through the arrangement of the belt assemblies 9, the door skins on multiple conveying mechanisms 2 can be gathered in one place, so that the door skins can be transported from a unified place to the cutting mechanism.

[0047] In this embodiment, the linear driving member 12, the up and down lifting member 19, and the up and down raising member 17 are cylinders, hydraulic cylinders, or electric push rods.

[0048] Specifically, the cutting mechanism includes left and right cutting units and front and rear cutting units. The left and right cutting units are used to cut the left and right sides of the door skin, while the front and rear cutting units are used to cut the front and rear sides of the door skin. In this embodiment, the left and right cutting units and the front and rear cutting units have the same structure, but are positioned at different angles. The left and right cutting units are connected by a conveyor device, so that the door skin passes through the left and right cutting units and the front and rear cutting units in sequence, thereby completing the cutting of the four sides of the door skin.

[0049] The left and right cutting units and the front and rear cutting units in this embodiment are both panel sizing saws disclosed in the invention patent with authorization announcement number CN109482960B.

[0050] In other embodiments, the door skin may pass through the front and rear cutting units and the left and right cutting units in sequence.

[0051] An alarm 7 is provided on the frame 4. When a certain specification of door skin is needed, the door skin in the corresponding material warehouse 1 will be transported to the corresponding conveying mechanism 2. At this time, the alarm 7 will emit sound and light to remind the surrounding people that the material warehouse 1 is working and please do not approach to prevent danger.

[0052] The working process of this utility model is as follows:

[0053] The user places multiple door skins on the support platform 3. After the gripper 16 grabs a door skin, it moves toward the conveying mechanism 2. The gripper 16 does not place the door skin completely on the roller 8 of the conveying mechanism 2. A part of it will still be on the support platform 3. At this time, the auxiliary roller 15 drives the door skin to move, and the guide roller 13 will press the door skin to prevent the door skin from being tilted too high. After the door skin is conveyed to the conveying mechanism 2, the roller 8 drives the door skin to move to the set position, and the belt assembly 9 lifts the door skin to separate the door skin from the roller 8. Then, the multiple belt assemblies 9 on the multiple brackets 6 drive the door skin to move to the cutting mechanism, and the cutting mechanism cuts the four sides of the door skin.
