Description

Technical Field

[0001] This invention relates to the field of mechanical technology, specifically to a fabric feeding mechanism. Background Technology

[0002] The fabric spreading machine has two modes: automatic fabric feeding and manual fabric feeding. In automatic fabric feeding mode, it feeds bed sheets and duvet covers, while in manual fabric feeding mode, it feeds pillowcases.

[0003] Currently, the automatic and manual fabric feeding switching devices for fabric spreading machines on the market have relatively complex structures, poor stability, and high manufacturing costs.

[0004] Currently, there is a lack of a simple mode switching structure. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a switching device for different fabric feeding modes of a fabric spreading machine, so as to solve at least one of the above technical problems.

[0006] To achieve the above objectives, the present invention provides a switching device for different fabric feeding modes of a fabric spreading machine, including a fabric feeding mechanism for manual conveying. The fabric feeding mechanism includes a conveyor belt, a retractable fabric feeding table, and a telescopic drive mechanism for sliding the fabric feeding table. The fabric feeding table includes a connecting frame, a first roller shaft, and a second roller shaft. The first roller shaft and the second roller shaft are respectively connected to both ends of the connecting frame. The connecting frame is slidably connected to the frame of the fabric spreading machine, and the telescopic drive mechanism drives the connecting frame to slide.

[0007] The frame of the spreading machine is equipped with fixed rollers;

[0008] The conveyor belt is arranged in a serpentine pattern, winding from top to bottom around the first roller shaft, the second roller shaft, and the fixed roller shaft.

[0009] It also includes a conversion mechanism, which includes a conversion plate and a swing drive mechanism for driving the conversion plate to swing, wherein the conversion plate is located in front of the extension direction of the fabric feeding table;

[0010] When the feeding table needs to extend, the conversion plate swings, providing space for the feeding table to extend. After the feeding table extends into place, the connecting frame of the feeding table is located above the conversion plate. At this time, manual feeding mode is used to place the material onto the feeding table for transfer.

[0011] When the feed table retracts to its position, the conversion plate swings, forming a negative pressure suction channel between the conversion plate and the feed table. The negative pressure suction channel is used for negative pressure suction and leveling of the edge of the fabric in automatic feeding mode.

[0012] This invention optimizes the structure, facilitating rapid switching between manual and automatic feeding modes.

[0013] More preferably, a negative pressure suction chamber is provided below the feeding platform, and the negative pressure suction chamber is connected to the negative pressure suction channel.

[0014] More preferably, in the automatic feeding mode, the conversion plate is in the flipped-up state and the feeding table is in the retracted state. At this time, a negative pressure suction channel is formed between the conversion plate and the feeding table.

[0015] In manual feeding mode, the conversion plate is in the folded-down state and the feeding table is in the extended state. The feeding table is used for manual feeding.

[0016] More preferably, the swing drive mechanism includes a swing drive cylinder, and the telescopic end of the swing drive mechanism is connected to a swing arm, which is drively connected to the conversion plate.

[0017] More preferably, the swing drive mechanism is installed on both opposite sides of the conversion plate.

[0018] More preferably, the first roller is installed at the front end of the connecting frame, and the second roller is installed below the rear end of the connecting frame.

[0019] More preferably, a support plate is installed at both ends of the first roller shaft along its length, and the support plate is provided with an upwardly extending extension portion;

[0020] The support plate is fixedly connected to the connecting frame;

[0021] The telescopic drive mechanism includes a telescopic drive cylinder, and the telescopic end of the telescopic drive cylinder is connected to the extension portion.

[0022] More preferably, there are two telescopic drive mechanisms, which are located on both sides of the fabric feeding table.

[0023] More preferably, the frame of the spreading machine is equipped with a self-feeding conveying mechanism, which is located above the feeding table.

[0024] In automatic feeding mode, the two corners of the fabric are clamped and stretched flat by the robotic arm and then pressed tightly against the conveying mechanism. The other two corners of the fabric droop down and are flattened under the action of the negative pressure suction channel. The conveying mechanism then feeds the flattened fabric by itself.

[0025] Beneficial effects: This invention enables the switching between manual and automatic fabric feeding modes, allowing the machine to switch freely and conveniently between the two modes. The new switching device simplifies the traditional structure, increases the stability of mode switching, and reduces manufacturing costs. Attached Figure Description

The fabric feeding table includes a connecting frame 7, a first roller 5, and a second roller 8. The two ends of the connecting frame 7 are respectively connected to the first roller 5 and the second roller 8. The connecting frame 7 is slidably connected to the frame 10 of the fabric spreading machine. The telescopic drive mechanism 3 drives the connecting frame 7 to slide. A fixed roller 6 is installed on the frame 10 of the fabric spreading machine. The conveyor belt 2 is serpentinely wound around the first roller 5, the second roller 8, and the fixed roller 6 from top to bottom. The conveyor belt passes through the right side of the first roller, the left side of the second roller, and the right side of the fixed roller. Furthermore, the conveyor belt passes through the area between the lower end of the first roller and the upper end of the second roller, and the area between the lower end of the second roller and the upper side of the fixed roller.

[0036] It also includes a conversion mechanism, which includes a conversion plate 4 and a swing drive mechanism 11 for driving the conversion plate 4 to swing. The conversion plate 4 is located in front of the feed table in the extension direction.

[0037] When the feeding table needs to extend, the conversion plate 4 swings, providing space for the feeding table to extend. After the feeding table extends into place, the connecting frame 7 of the feeding table is located above the conversion plate 4. At this time, the manual feeding mode is activated, and the material is placed on the feeding table for transfer.

[0038] After the fabric feeding table retracts into position, the conversion plate 4 swings, forming a negative pressure suction channel between the conversion plate 4 and the fabric feeding table. This negative pressure suction channel is used for negative pressure suction and leveling of the fabric edges in automatic feeding mode. This invention, through optimized structure, facilitates rapid switching between manual and automatic feeding modes.

[0039] A negative pressure suction chamber is installed below the feeding platform, and the negative pressure suction chamber is connected to the negative pressure suction channel.

[0040] In automatic feeding mode, the conversion plate 4 is in the upward state and the feeding table is in the retracted state. At this time, a negative pressure suction channel is formed between the conversion plate 4 and the feeding table.

[0041] In manual feeding mode, the conversion plate 4 is in the down position and the feeding table is in the extended position. The feeding table is used for manual feeding.

[0042] The swing drive mechanism 11 includes a swing drive cylinder. The telescopic end of the swing drive mechanism 11 is connected to a swing arm, which is connected to the conversion plate 4 in a transmission manner. Swing drive mechanisms 11 are installed on opposite sides of the conversion plate 4.

[0043] A first roller 5 is fixed to the front end of the connecting frame 7, and a second roller 8 is installed below the rear end of the connecting frame 7. A support plate is installed at both ends of the first roller 5 along its length, and the support plate has an upwardly extending extension; the support plate is fixedly connected to the connecting frame 7; the telescopic drive mechanism 3 includes a telescopic drive cylinder, the telescopic end of which is connected to the extension. Two telescopic drive mechanisms 3 are provided, and the two telescopic drive mechanisms 3 are located on both sides of the fabric feeding table. A sliding rail 9 is installed on the inner wall of the frame 10. The sliding rail 9 is slidably connected to the fabric feeding table.

[0044] The frame 10 of the fabric spreading machine is equipped with a conveyor mechanism 1 for self-feeding, which is located above the feeding table. In automatic feeding mode, the two corners of the fabric are clamped and stretched flat by the robotic arm and then pressed tightly against the conveyor mechanism 1. The other two corners of the fabric hang down and are flattened under the action of the negative pressure suction channel. The conveyor mechanism 1 then feeds the flattened fabric by itself.

[0045] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
