DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Please see the attached Figure 1-12 The automatic fitted sheet elastic band wrapping machine described in the present invention includes a base 1, a lifting assembly 2, a fitted sheet transmission assembly 3, a fitted sheet folding mechanism 4, an elastic band feeding mechanism 5 and a sewing machine 7; the lifting assembly 2 is installed on the base 1; the fitted sheet transmission assembly 3 is arranged on the base 1 through the lifting assembly 2, and the lifting assembly 2 is composed of a motor and a screw rod, which is used to drive the fitted sheet transmission assembly 3 to move up and down on the base 1, and the fitted sheet transmission assembly 3 is used to place the fitted sheet and control the transmission of the fitted sheet; the fitted sheet folding mechanism 4 is arranged above the fitted sheet transmission assembly, and the fitted sheet folding mechanism 4 is used to fold the fitted sheet to facilitate subsequent elastic band wrapping; the elastic band feeding mechanism 5 is arranged on one side of the fitted sheet folding mechanism 4; the sewing machine 7 is arranged on one side of the fitted sheet folding mechanism 4.

[0040] As a further preferred embodiment, the fitted sheet transmission assembly 3 includes a placement surface 31 and a clamping and positioning assembly 32 arranged opposite to each other, and an active transmission wheel 6 is provided above the placement surface 31; the clamping and positioning assembly 32 includes a base plate 321 rotatably arranged on the frame 30 driven by a first cylinder 320, and a pressing plate 323 driven by a second cylinder 322 to be pressed against the base plate is provided above the base plate 321, and a pressing inner plate 328 is further provided on the side of the pressing plate 323 opposite to the base plate 321, and the pressing inner plate 328 is connected to the pressing plate 323 by a spring, so that the fitted sheet can be pressed between the base plate and the pressing inner plate during actual work.

[0041] A fitted sheet corner detection assembly is provided above the bottom plate, and the fitted sheet corner detection mechanism is used to detect the four corners of the fitted sheet; the fitted sheet corner detection assembly includes a first roller 324 located above the bottom plate 321, and one end of the first roller 324 is closely attached to a second roller 325 that can rotate around the first roller 324; one end of the second roller 325 is provided with a detection block 326, and the opposite side of the detection block 326 is provided with a counting sensor 327, and the counting sensor 327 is used to sense the position of the detection block 326 and count.

[0042] In the initial state, the first roller and the second roller are closely attached to each other. Because a fitted sheet has four corners, each of which is convex, when each corner of the fitted sheet enters between the first roller and the second roller, it lifts the second roller, causing the detection block 326 to perform a corresponding action. Each time the detection block 326 moves, the counting sensor 327 counts once. When the counting sensor 327 counts four times, it indicates that the fitted sheet has been transferred, and the corresponding control system controls the subsequent elastic detection component to start working.

[0043] Specifically, the rubber band detection assembly is arranged between the clamping inner plate 328 and the bottom plate 321. The rubber band detection assembly is used to detect the position of the rubber band. The rubber band detection assembly includes a rotating shaft 355 located above the clamping plate 323, and the rotating shaft 355 passes through the bottom plate 32; one end of the rotating shaft 355 located above the clamping plate 323 is provided with a sensing member 356, and the other end of the rotating shaft 355 is provided with a rotating member 357 that rotates synchronously with the sensing member 356. A sensor 358 is provided on one side of the sensing member 356 for sensing the position of the sensing member 356.

[0044] The control system sends a signal to the elastic detection component, indicating that the four sides of the fitted sheet have been elastically hemmed. At this time, the elastic detection component starts working. When the elastic contacts the rotating member 357, the rotating member 357 is driven to rotate, thereby driving the sensing member 356 to rotate synchronously. The sensor 358 senses the position of the sensing member 356 and controls the device to stop working. The elastic hemming process of the fitted sheet is completed. A certain delay is also adopted here to ensure the completion of the elastic hemming.

[0045] In addition, the bottom plate 32 is further provided with two correcting components arranged in an upper and lower manner. The correcting components include a correcting seat 330. The correcting seat 330 is provided with a correcting cylinder 331. The correcting cylinder 331 drives a rotating block 332 to rotate on an adapter frame 333. The adapter frame 333 is provided on the correcting seat 331; the rotating block 332 is provided with an adjusting wheel 334 that passes through the bottom plate 32. The correcting cylinder is used to drive the adjusting wheel 334 to swing left and right, thereby correcting the position of the fitted sheet.

[0046] Furthermore, a plurality of grooves 655 are provided at the bottom of the bottom plate 321 and the pressing plate 323. A plurality of air blowing tubes 654 are provided around the grooves, and the nozzles of the air blowing tubes are directed toward the grooves. The air blowing tubes 654 are used to blow air onto the surface of the fitted sheet, thereby ensuring that the fitted sheet is fully unfolded without wrinkles.

[0047] As a further preferred embodiment, the rubber feeding mechanism 5 includes a rubber feeding wheel 60 and a rubber feeding seat 50 that are relatively arranged. A transverse cylinder 52 that can move up and down via a lifting cylinder 51 is provided above the rubber feeding seat 50; the transverse cylinder 52 drives the carrier 53 to move forward and backward; a vertical rod 54 is provided at the front end of the carrier 53, a pressure plate 55 is provided at the bottom of the vertical rod 54, and a first pull cylinder portion 45 is provided at one end of the pressure plate 55; an angle-adjustable adjustment block is provided on the carrier 53 56; a vertical bracket 57 is provided at the front end of the adjusting block 56; a rubber feeding pipe 58 is provided at the bottom of the vertical bracket 57, and the rubber feeding pipe 58 is L-shaped; a rubber guide frame 59 connected to the vertical bracket 57 is provided above the rubber feeding pipe 58; air blowing pipes 590 are provided on both sides of the rubber feeding pipe 59, and the air blowing port of the air blowing pipe 590 is provided inside the rubber feeding pipe 59, and the air blowing port is set downward, and the air blown out of the air blowing pipe is used to blow the rubber to ensure the feeding direction of the rubber.

[0048] In addition, a cutting mechanism is provided above the rubber band feeding tube 59 for cutting the rubber band; the cutting mechanism includes a shearing cylinder 530 provided on the supporting frame 53, and a movable block 531 is provided on the piston rod of the shearing cylinder 530. The movable block 531 is provided with a rotating shaft 532 rotatably arranged in the vertical bracket 57, and the bottom of the rotating shaft 532 passes through the vertical bracket and is connected to the cutter 533, and the cutter 533 is located at the top of the rubber band feeding tube 58.

[0049] A rubber driving wheel 580 and a driven wheel 581 are provided between the rubber feeding tube 58 and the rubber guide frame 59. The rubber driving wheel 580 drives the rubber on the rubber feeding wheel 60 to be transferred from the rubber guide frame 59 to the rubber feeding tube 58. Then the rubber is sent out from the tail end of the rubber feeding tube 58 and merges with the folded edge of the fitted sheet. The rubber is wrapped in the folded edge. When the rubber needs to be cut, the shear cylinder drives the cutter to swing left and right through the movable block, thereby achieving the cutting of the rubber.

[0050] The fitted sheet folding mechanism 4 includes a folding bracket 40, and the folding bracket 40 has a folding placement surface 41; a pre-folding plate 42 is provided on the folding surface 41, and a second pull cylinder portion 43 is provided at the front end of the pre-folding plate 42, and the first pull cylinder portion 45 and the second pull cylinder portion 43 constitute a folding assembly for folding the fitted sheet, realizing the function of folding the fitted sheet, and a third pull cylinder portion 44 is provided at the front end of the second pull cylinder portion 43, and the front ends of the third pull cylinder portion 44 and the second pull cylinder portion 43 constitute a wrapping assembly for wrapping the elastic band around the folded edge of the fitted sheet.

[0051] The process of wrapping the rubber band around the folded edge of the fitted sheet is as follows: first, the transverse cylinder 52 in the rubber band feeding mechanism 5 is used to drive the first pull cylinder portion toward the second pull cylinder portion, so that the first pull cylinder portion 45 and the second pull cylinder portion 43 form a folding assembly, and then the fitted sheet is pre-folded at the pre-folding plate, and then the folding assembly is used to complete the folding of the fitted sheet; at the same time, the rubber band is fed out from the rubber band feeding wheel 60, and passes through the rubber band guide frame 59, the rubber band driving wheel 580 and the driven wheel 581 in turn, and then enters the rubber band feeding pipe 58, wherein the power for the rubber band transmission is provided by the rubber band driving wheel 580, and the air blow pipe is used to ensure that the rubber band fits the folded edge of the fitted sheet when it is fed out, and when the rubber band comes out, it is just at the folded edge of the fitted sheet, and then passes through the third pull cylinder portion, and the folded edge of the fitted sheet completely wraps the rubber band and is then fed out.

[0052] When the fitted sheet needs to be taken out, the transverse cylinder 52 in the elastic feeding mechanism 5 drives the first pull-tube portion to move away from the second pull-tube portion, thereby loosening the elastic-wrapped fitted sheet and taking it out.

[0053] The working principle of this automatic fitted sheet elastic band wrapping machine is as follows:

[0054] Place the fitted sheet on the fitted sheet transfer assembly and use the placement surface, folding edge surface and clamping and positioning assembly to place and position it. At this time, one end of the fitted sheet is clamped between the bottom plate and the pressing inner plate. The lifting assembly is turned on to raise the entire fitted sheet to a certain height to prevent the fitted sheet from dragging on the floor during processing.

[0055] The active transmission wheel 6 drives the fitted sheet to be transferred on the placement surface, the folding surface and the clamping and positioning assembly. When the fitted sheet enters the fitted sheet folding mechanism, the folding assembly composed of the first pull-cylinder portion and the second pull-cylinder portion folds the fitted sheet. At the same time, rubber is fed out from the rubber feeding tube, and the elastic band enters the folded edge of the fitted sheet. The cutting mechanism cuts the elastic band, and then the tightening assembly composed of the first pull-cylinder portion and the third pull-cylinder portion is used to wrap the elastic band tightly around the folded edge of the fitted sheet. Finally, the fitted sheet wrapped with the elastic band is transferred to the sewing machine for sewing.

[0056] During the process of wrapping the fitted sheet with elastic, the four corners of the fitted sheet are sensed by the four corner detection components to determine whether the four sides of the fitted sheet have been transmitted. Then the elastic detection component starts working to determine whether the elastic wrapping of the fitted sheet is completed, thereby realizing automatic control of the production and processing of the fitted sheet. When the elastic detection component detects that the processing of the fitted sheet is completed, the transverse cylinder drives the first pull-cylinder part to move to the second pull-cylinder part, and the upgraded component is used to lower the fitted sheet to the appropriate position, and finally the finished product can be taken out.

[0057] The automatic fitted sheet wrapping machine of the present invention has a compact overall structure and is easy to operate. After the fitted sheet is raised to a certain height, the entire process of folding the edge of the fitted sheet, feeding the rubber, and wrapping the rubber around the folded edge of the fitted sheet is fully automatically completed, thereby achieving the function of wrapping the elastic band of the fitted sheet, reducing labor costs, improving production efficiency, and meeting the production and processing needs of the enterprise.

[0058] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solutions formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
