Description

Technical Field

[0001] This utility model relates to the field of pillowcase production equipment, and in particular to the folding mechanism of an envelope-type pillowcase machine. Background Technology

[0002] Traditional manual cutting and sewing of pillowcases by hand results in large errors in product uniformity and low production efficiency. Automated pillowcase making machines achieve streamlined production by cutting fabric to fixed lengths, folding and sewing the horizontal edges, folding it into an envelope shape, and sewing the vertical edges. After the short edges of each cut pillowcase fabric are sewn, they are transported by a carrier to the support platform at the front of the folding mechanism. Then, the two dragging components of the folding mechanism respectively hold the two short edges of the pillowcase fabric and drag them away, working together to fold it into an envelope shape. Figure 5 As shown. Mop assembly one drags pillowcase fabric end a S1 from the rear end of the mop folding space to the front end, completing the flipping of the pillowcase fabric. At this point, end a is on the left and end b is on the right. Then, mop assembly two drags pillowcase fabric end b S2 from right to left forward to the back of end a. Next, mop assembly one drags end a S1 from left to right in the opposite direction, over end b, to the right side of S2. Then, end a is released to form an envelope-shaped pillowcase. Because the folding edge distance S2 is difficult to control when end a is dragged in the opposite direction, and the fabric tends to fall and drape unevenly when mop assembly one releases end a, the product accuracy is affected. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an envelope-type pillowcase folding mechanism. The pressure tongue piece provided on the front side of the two claws of the mop assembly plays a positioning role. The reverse dragging of end A ensures accurate folding edge distance and prevents displacement during placement.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The envelope-style pillowcase folding mechanism includes a frame, a support platform, a pressing assembly, a first mop assembly, a second mop assembly, and a forming and placing platform. The frame has a mop folding space. The two support platforms are positioned at the rear of the mop folding space with a relative gap. The forming and placing platform is located in front of the support platforms. The two pressing assemblies are respectively located above the outer edges of the support platforms and are used to press the two short sides of the pillowcase fabric together. The first and second mop assemblies are mounted on the frame, and their grippers respectively hold the short sides of the pillowcase fabric and drag the pillowcase fabric laterally. The pillowcase fabric is formed into an envelope-style pillowcase on the forming and placing platform by the cooperation of the first and second mop assemblies. The grippers of the second mop assembly are provided with a pressure tongue on the front side.

[0005] A further improvement is that the tongue depressor is mounted on the longitudinal moving assembly, and the distance between the tongue depressor and the gripper of the second mop assembly is adjustable. This adjustment is possible according to design requirements.

[0006] A further improvement is that the pressure tongue is connected to the lead screw nut via a mounting bracket, the connecting plate is fixed to the base of the rotary motor, the lead screw drive motor is fixed to the connecting plate, the mounting bracket is slidably connected to the slide rail on the connecting plate, and the gripper of the second mop assembly is connected to the rotating shaft of the rotary motor.

[0007] A further improvement is to install an air blowing device above the grippers of the second mop assembly, with the air nozzle of the air blowing device pointing downwards. This prevents the pillowcase fabric from wrinkling when it is delivered to the support table from the previous process carrier.

[0008] A further improvement is that the first mop assembly includes a first mop frame, a first mop slide, and a first clamping assembly; the second mop assembly includes a second mop frame, a second mop slide, and a second clamping assembly. The first and second mop frames are mounted on a frame above the mop folding space. The slide rail of the first mop frame is located below the two slide rails of the second mop frame. The first mop slide is laterally movable on the slide rail of the first mop frame via a first synchronous belt assembly. Two opposing clamping assemblies are mounted at both ends of the bottom of the first mop slide. The second mop slide is laterally movable on the slide rail of the second mop frame via a second synchronous belt assembly. Two opposing clamping assemblies are mounted at both ends of the bottom of the second mop slide. The first and second clamping assemblies are vertically aligned.

[0009] A further improvement is that the gripping assembly includes a first lifting cylinder, an upper gripper cylinder is provided at the bottom of the first lifting cylinder, a first upper pressure plate is provided on the piston rod of the upper gripper cylinder, and a first lower pressure plate connected to the upper gripper cylinder is provided below the first upper pressure plate.

[0010] A further improvement is that any one of the clamping components is longitudinally movable on the mop slide via a longitudinal power component.

[0011] A further improvement is that the second clamping assembly includes a longitudinal movement cylinder connected to the second mop slide, a second lifting cylinder connected to the piston rod of the longitudinal movement cylinder, a rotary motor at the bottom of the second lifting cylinder, and two grippers that can clamp each other via a clamping cylinder at the front end of the rotary motor.

[0012] A further improvement is that any one of the clamping components two is longitudinally movable on the mop slide two via the longitudinal power component two. Beneficial effects

[0013] The present invention comprises two mop components, namely, Mop Component 1 and Mop Component 2, which respectively clamp the two short sides of the pillowcase fabric and drag it along, working together to fold it into an envelope-shaped pillowcase structure. This design ensures precise operation, neat products, improved finished product qualification rate, and increased overall pillowcase production efficiency. Attached Figure Description

The second mop assembly 5 includes a second mop frame 51, a second mop slide 52, a clamping assembly 53, a timing belt assembly 54, and a longitudinal power assembly 55. The first mop frame 41 and the second mop frame 51 are mounted on the frame 1 above the mop folding space. The slide rail of the first mop frame 41 is located below the two slide rails of the second mop frame 51. The first mop slide 42 can move laterally via the timing belt assembly 44. Mounted on the slide rail of the mop holder 41, two opposing clamping assemblies 43 are installed at both ends of the bottom of the mop slide block 42, and any one of the clamping assemblies 43 is longitudinally movable on the mop slide block 42 via the longitudinal power assembly 45 (module). The clamping assembly 43 includes a first lifting cylinder 431, an upper gripper cylinder 432 is provided at the bottom of the first lifting cylinder, a first upper pressure plate 433 is provided on the piston rod of the upper gripper cylinder, and a first lower pressure plate 434 connected to the upper gripper cylinder is provided below the first upper pressure plate 433.

[0017] The second mop slide block 52 is laterally movable on the slide rail of the second mop frame 51 via the second synchronous belt assembly 54. Two opposing clamping assemblies 53 are installed at both ends of the bottom of the second mop slide block 52, and either clamping assembly 53 is longitudinally movable on the second mop slide block 52 via the second longitudinal power assembly 55 (module). The clamping assembly 53 includes a longitudinal movement cylinder 531 connected to the second mop slide block 52. A second lifting cylinder 532 is connected to the piston rod of the longitudinal movement cylinder 531. A rotary motor 533 is provided at the bottom of the second lifting cylinder 532, and two grippers 535 that can clamp each other via the clamping cylinder 534 are provided at the front end of the rotary motor. The first clamping assembly 43 and the second clamping assembly 53 are arranged vertically. The purpose of this arrangement is to ensure that when the first clamping assembly drags the pillowcase cloth to the left, the second clamping assembly will not obstruct the mopping action of the first clamping assembly.

[0018] The front side of the gripper 535 of the second mop assembly 5 is provided with a pressure tongue 7, which is mounted on the longitudinal moving assembly 8. The distance between the pressure tongue 7 and the gripper 535 of the second mop assembly is adjustable.

The gripper 535 of the second mop assembly 53 is connected to the rotating shaft of the rotary motor 533.

[0019] The process of folding the pillowcase fabric to form an envelope-shaped pillowcase is as follows: First, the rectangular pillowcase fabric, formed by cutting and sewing the short sides, is conveyed by a carrier to the support platform at the front of the folding mechanism. The pressing assembly then connects to the connector, pressing the two short sides of the pillowcase fabric firmly against the support platform, with the center positioned between the two support platforms, as shown in the attached diagram. Figure 8 As shown; the two ends of the pillowcase fabric are end a S1 and end b S2, respectively.

[0020] Next, the mop assembly one and the mop assembly two work, clamping assembly one and clamping assembly two clamp the a end S1 and the b end S2 respectively, and then the pressing assembly moves away.

[0021] Clamping component one grips end A and drags it from right to left onto the forming platform, completing the pillowcase fabric flipping. At this point, end A is on the left and end B is on the right. Then, clamping component two rotates end B counterclockwise using a rotary motor, flipping end B onto the pillowcase fabric. Clamping component two then drags end B from right to left to a preset position behind end A. At this point, clamping component one drags end A in the opposite direction from left to right, over end B. At this point, the folded area of ​​end A is limited by the pressure tongue. The grippers of clamping component one release end A, and clamping component two also withdraws from the pillowcase fabric towards the edge, completing the entire folding process of the pillowcase shape. The structure of the pillowcase is shown in the attached figure. Figure 9 As shown.

[0022] Additionally, an air blowing device is provided above the gripper 535 of the mop assembly two, with the air blowing pipe 9 of the air blowing device pointing downwards. Air is blown onto the pillowcase fabric to prevent wrinkles when the pillowcase fabric is delivered to the support table from the previous process carrier.
