DETAILED DESCRIPTION

[0028] In order to further explain the technical solutions of the present application, the following will be described in detail through specific examples.

[0029] As shown in Figure 1 The present application provides an automatic wrapping equipment for furniture board packaging, which comprises a wrapping box 1, a foam cotton wrapping machine 2 connected with the wrapping box 1, a support frame 3 horizontally passing through the inner side of the wrapping box 1, a belt conveyor 4 arranged at each of the left and right ends of the inner side of the support frame 3, and two belt conveyors 4 respectively contacting the left and right ends of the bottom of the furniture board to cooperate with the conveying of the furniture board.

[0030] As shown in Figure 1 In this embodiment, a U-shaped frame 6 is arranged at each of the left and right ends of the top of the support frame 3 and is slidingly connected with the inner side of the wrapping box 1, which is used to apply a pushing force to the furniture board to adjust the position of the furniture board so that the furniture board can be aligned with the foam cotton wrapping machine 2, and the support frame 3 is internally provided with a supporting mechanism 5 for supporting the furniture board.

[0031] A bidirectional air cylinder 8 and a camera 10 are arranged above the front of the supporting mechanism 5 and are connected with the top of the inner side of the wrapping box 1, the bidirectional air cylinder 8 is movably connected with the top of the inner side of the wrapping box 1, and the camera 10 is fixedly connected with the top of the inner side of the wrapping box 1 and is used to detect the position of the furniture board.

[0032] The U-shaped frame 6 is connected with the inner side of the wrapping box 1 through a connecting piece, and a plurality of guide rollers 7 are movably arranged in each U-shaped frame 6, which contact the furniture board through the guide rollers 7 to reduce the abrasion of the furniture board caused by the direct contact of the U-shaped frame 6 with the furniture board.

[0033] An auxiliary mechanism 9 corresponding to the foam cotton wrapping machine 2 is arranged on the piston rod of the bidirectional air cylinder 8, which is used to assist in guiding the wrapping of the foam cotton on the furniture board.

[0034] In this embodiment, the connecting piece comprises a motor 11 fixedly connected to the side surface of the wrapping box 1, and a bidirectional screw rod 12 coaxially connected with the output shaft of the motor 11, the bidirectional screw rod 12 is rotatably connected with the inner side of the wrapping box 1, and the outer top of the U-shaped frame 6 is provided with a screw hole which cooperates with the inner ring of the bidirectional screw rod 12, so that the U-shaped frame 6 is driven to move horizontally in the wrapping box 1 through the cooperation of the bidirectional screw rod 12 and the screw hole, so as to realize the horizontal movement of the guide rollers 7 driven by the U-shaped frame 6 to adjust the position of the furniture board.

[0035] In this embodiment, the bidirectional air cylinder 8 is slidingly connected with the top of the inner side of the wrapping box 1, and an adjusting air cylinder 14 is arranged at the rear of the bidirectional air cylinder 8 and is mounted on the top of the inner side of the wrapping box 1, the front piston rod of the adjusting air cylinder 14 is connected with the bidirectional air cylinder 8, and the bidirectional air cylinder 8 is driven to move horizontally by the adjusting air cylinder 14, so as to realize the horizontal movement of the auxiliary mechanism 9 driven by the bidirectional air cylinder 8 for position adjustment.

[0036] like Figure 2 As shown, in this embodiment, the support mechanism 5 includes a fixed plate 51 locked and fixed in the support frame 3, an electric push rod 52 vertically fixed on the upper end of the fixed plate 51, and a support plate 53 connected to the piston rod at the top of the electric push rod 52 and located between the left and right opposite sides of the two belt conveyors 4. The support plate 53 is used to lift the furniture board upwards so that the furniture board is facing the foam cotton wrapping machine 2. A guide rod 54 is provided at each of the four ends of the bottom of the support plate 53, and a positioning frame 56 is fixedly installed at the front end of the top of the support plate 53. A guide cylinder 55 corresponding to the guide rod 54 is installed at each of the four ends of the top of the fixed plate 51. Several positioning rollers 57 are rotatably installed in the positioning frame 56. The positioning rollers 57 provide positioning for the furniture board so that the furniture board can be stably facing the foam cotton wrapping machine 2.

[0037] In this embodiment, several limiting rods 13 are installed on the inner top of the package box 1. The limiting rods 13 are located above the tray 53. The furniture board is clamped and fixed by the limiting rods 13 and the tray 53 to prevent the furniture board from shifting under force when wrapping the foam cotton cover.

[0038] In this embodiment, the limiting rod 13 is made of rubber, which helps to protect the upper surface of the furniture board and prevent the upper surface of the furniture board from being damaged by extrusion.

[0039] The positioning rollers 57 inside the positioning frame 56 are evenly distributed, and the outer diameter of the positioning rollers 57 is larger than the inner width of the positioning frame 56, so that the positioning rollers 57 can stably contact the furniture board.

[0040] In this embodiment, the camera 10 is connected to an external smart computer via a transmission cable so that the camera 10 can work with the external smart computer to check the position of the furniture board, which is the prior art.

[0041] In use, the furniture board is conveyed to the package box 1 by the belt conveyor 4. When the furniture board moves to the contact positioning roller 57, it stops moving. Then, the electric push rod 52 drives the pallet 53 to move upward. The pallet 53 then drives the furniture board to move upward and get off the belt conveyor 4. The furniture board moves upward and contacts the limit rod 13. The limit rod 13 and the pallet 53 clamp the furniture board according to the specified position.

[0042] Next, camera 10 takes pictures of the furniture board and transmits the pictures to an externally connected computer. The computer processes the pictures to determine whether the furniture board is centered and straight. When the furniture board is off-center, motor 11 drives the double-acting screw 12 to rotate. The double-acting screw 12, connected to the screw holes on the two U-shaped frames 6, drives the two U-shaped frames 6 to move inward. The two U-shaped frames 6 drive the built-in guide rollers 7 to move inward and apply a pushing force to the furniture board. The furniture board is straightened and centered by the pushing force, in preparation for the subsequent foam cotton wrapping work.

[0043] like Figures 3 to 5 As shown, in this embodiment, the auxiliary mechanism 9 includes a connecting rod 91 connected to the piston rod of the bidirectional cylinder 8. The connecting rod 91 is movably inserted into the fixed cylinder 92. The fixed sleeve 92 can move vertically and rotate horizontally along the connecting rod 91. The fixed cylinder 92 is vertically fixedly connected to the top of the guide seat 94.

[0044] The guide seat 94 is directly opposite the foam output end of the foam wrapping machine 2, and the guide seat 94 has a connection hole 95 inside. At the same time, the side surface of the guide seat 94 is equipped with an air inlet pipe 96 that communicates with the inside of the connection hole 95. The air inlet pipe 96 is used to transport external gas into the connection hole 95, and then the gas is transported into the slide groove 97 to push the piston 98 to move. A slide groove 97 is opened at both the upper and lower ends of the inner side of the connection hole 95, and a piston 98 is slidably installed in each slide groove 97.

[0045] The piston 98 is connected to the inner wall of the slide groove 97 via the spring 99, which facilitates the piston 98 to be reset by the elastic force of the spring 99. A T-shaped piston rod 910 is installed at the end of the piston 98 away from the connection hole 95, which can pass through the spring 99 and the inner side of the guide seat 94. An L-shaped support tube 910 is installed at each of the front and rear ends of the T-shaped piston rod 910. The L-shaped support tube 910 is used to provide support for the inner side of the foam cotton.

[0046] In this embodiment, a wing bolt 93 passes horizontally through the top of the outer side of the fixing cylinder 92. After passing through the side surface of the fixing cylinder 92, the wing bolt 93 is tightly attached to the outer end face of the connecting rod 91, which makes it easy to fix the position of the fixing cylinder 92 by means of the wing bolt 93.

[0047] In this embodiment, the side surface of the fixed cylinder 92 is provided with a screw hole that mates with the wing bolt 93, which facilitates the connection between the wing bolt 93 and the fixed cylinder 92, prevents the wing bolt 93 from falling off the fixed cylinder 92, and facilitates the wing bolt 93 to work with the connecting rod 91 to fix the position of the fixed cylinder 92.

[0048] In use, adjust the pneumatic device connected to the bidirectional cylinder 8 so that the extension and retraction speed of the piston rod of the bidirectional cylinder 8 corresponds to the foam output speed of the foam wrapping machine 2. When the foam wrapping machine 2 conveys the foam sleeve to the furniture board, the T-shaped piston rod 910 and the L-shaped support tube 910 first enter the foam sleeve. Then, the pneumatic device connected to the air inlet pipe 96 inputs gas into the air inlet pipe 96. The gas enters the connecting hole 95 through the air inlet pipe 96 and then enters the slide groove 97 through the connecting hole 95. The piston 98 is pushed outward within the chute 97. The piston 98 drives the T-shaped piston rod 910 and the L-shaped support tube 910 to move outward, applying a pushing force to the foam cotton cover. The foam cotton cover expands outward at its open end due to the pushing force. When the foam cotton wrapping machine continuously conveys the foam cotton cover, it controls the contraction of the bidirectional cylinder 8. The bidirectional cylinder 8 drives the guide seat 94, the T-shaped piston rod 910 and the L-shaped support tube 910 to move synchronously until the T-shaped piston rod 910 and the L-shaped support tube 910 wrap the foam cotton cover around the furniture board.

[0049] Then, the adjusting cylinder 14 drives the bidirectional cylinder 8, the T-shaped piston rod 910, and the L-shaped support tube 910 to move outward and detach from the foam cotton sleeve. At the same time, the electric push rod 52 drives the pallet 53, the positioning frame 56, and the positioning roller 57 to move downward. The pallet 53 drives the furniture board wrapped with the foam cotton sleeve to move downward to the belt conveyor 4 until the positioning roller 57 detaches from the front end of the furniture board. At this time, the belt conveyor 4 transports the furniture board outward and detaches it from the packaging box 1 to complete the automated wrapping of the furniture board. The wrapped furniture board is ready for subsequent packaging work.

[0050] This invention provides an automatic wrapping device for furniture board packaging. The U-shaped frame 6 and guide roller 7 move inward to push the furniture board, so that the offset furniture board is centered and straightened by the thrust, which makes it easier for the foam wrapping machine 2 to wrap the foam cotton sleeve more accurately on the furniture board. Before the foam cotton sleeve is wrapped on the furniture board, the T-shaped piston rod 910 drives the L-shaped support tube 910 to move outward, which causes the foam cotton sleeve to expand outward, increasing the size of the wrapping port of the foam cotton sleeve, making it easier for the foam cotton to be wrapped stably on the furniture board, reducing the collision between the foam cotton sleeve and the furniture board, and improving the wrapping quality of the foam cotton.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
