Abstract
Description
Technical Field
[0001] This utility model relates to the field of pillowcase production equipment, and in particular to a short-side pressing device for 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 length, hemming the horizontal edges, folding it into an envelope shape, and sewing the vertical edges. After each cut pillowcase fabric is sewn along its short edges, it is transported by a carrier to a transfer table at the front of the folding mechanism. The folding mechanism then pulls the fabric away, folding it into an envelope shape. The transfer table coordinates the operation of the preceding and following processes. When the two short edges of the pillowcase fabric are pressed against the transfer table, they form a U-shape. Due to the downward pull of gravity in the middle of the fabric, the two ends of the pressed short edges are stretched and deformed. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides a short-side pressing device for an envelope-type pillowcase machine, which presses the pillowcase fabric sent by the receiving carrier, coordinates the collaborative operation of the preceding and following processes, and ensures that the pillowcase fabric is laid flat without deformation, which is more conducive to the subsequent folding mechanism to clamp and drag it.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The short-side pressing device for an envelope-type pillowcase machine includes two parallel supports spaced apart. A table is installed on top of each of the two supports. A receiving mechanism is provided on the outer side of each table. The receiving mechanism includes a pressure plate, a pressure plate frame, and a driving component. The pressure plate is installed at the front end of the pressure plate frame, and the driving component is connected to the pressure plate frame. The pressure plate is driven to move above and beside the outer side of the table.
[0005] A further improvement is that the pressure plate frame includes an "H"-shaped movable frame and a fixed vertical frame. The pressure plate is fixed to the front end of the longitudinal rod of the movable frame, and the rear part of the longitudinal rod of the movable frame is movably connected to the fixed vertical frame. The driving component includes telescopic rod one, telescopic rod two, and telescopic rod three. The rear ends of the two longitudinal rods of the movable frame are respectively connected to the telescopic ends of telescopic rod one and telescopic rod two, and the crossbar of the movable frame is connected to the telescopic end of telescopic rod three.
[0006] A further improvement is to install negative pressure fans on the supports under the tabletops on both sides. The negative pressure fans generate negative pressure air, which attracts the fabric and counteracts the pulling force caused by the fabric's gravity, preventing the horizontal edges of the pillowcase fabric on the tabletop from being stretched and deformed.
[0007] A further improvement is to arrange four negative pressure fans on one side of the support frame, two pairs of which are close to the left and right long sides of the fabric to be received. The middle part of the pillowcase fabric's horizontal edge is pressed down by the pressure plate, and the ends of the horizontal edge are subject to large traction deformation. Placing the negative pressure fans on the left and right sides will improve the effect.
[0008] A further improvement is that the tabletop is shaped like a "7", with the vertical plate of the tabletop located on the inner side of the support. The pillowcase fabric hangs down without wearing out.
[0009] A further improvement is to install baffles below the negative pressure fans on the inner sides of both brackets. The pillowcase fabric hangs neatly and close to the skin. Beneficial effects
[0010] 1. The carrier presses the pillowcase fabric from the previous process onto the transfer table. The drive unit pushes the pressure plate frame to flip from the two outer sides of the transfer table to the top of the outer side. The pressure plate presses the horizontal edge of the pillowcase fabric, and the carrier releases the pillowcase fabric and returns to its original position to resume the previous process. Then the folding mechanism drags away the pillowcase fabric for subsequent folding operations. The transfer table undertakes the coordination and matching work of the operation of the previous and subsequent processes.
[0011] 2. When the two short sides of the pillowcase fabric are pressed tightly onto the transfer table, they form a U-shape. Due to the downward pull of gravity in the middle of the fabric, the two ends of the pressed short sides will be stretched and deformed. The negative pressure fan generates negative pressure air, which adsorbs the fabric, counteracts the pulling force caused by the downward pull of the fabric's gravity, and makes the pillowcase fabric on the table surface lay flat without being stretched.

[0013] like Figure 1 , Figure 2As shown, this utility model includes two parallel supports 1 spaced apart, with a tabletop 2 installed on top of each support 1. The tabletop 2 is shaped like a "7". The vertical plate of the tabletop is located on the inner side of the support, and a receiving mechanism 3 is provided on the outer side of the tabletop 2. The receiving mechanism 3 includes a pressure plate 31, a pressure plate frame 32, and a driving component 33. The pressure plate frame 32 includes an "H"-shaped movable frame 321 and a fixed vertical frame 322. The driving component 33 includes a first telescopic rod 331, a second telescopic rod 332, and a third telescopic rod 333. The pressure plate 31 is fixed to the front end of the vertical rod of the movable frame 321. The rear part of the vertical rod of the movable frame 321 is movably connected to the fixed vertical frame 322. The rear ends of the two vertical rods of the movable frame 321 are respectively connected to the telescopic ends of the first telescopic rod 331 and the second telescopic rod 332. The horizontal rod of the movable frame 321 is connected to the telescopic end of the third telescopic rod 333. The pressure plate 31 is driven to move above the outer edge of the tabletop 2 and to the side of the outer edge of the tabletop 2. The horizontal edges S1 and S2 at both ends of the pillowcase fabric are pressed under the pressure plates of the two tabletops respectively. There is a gap between the two tabletops to accommodate the middle part of the pillowcase fabric, allowing the middle part of the pillowcase fabric to fall between the two tabletops.
[0014] Negative pressure fans 4 are installed on the brackets 1 below the table panels 2 on both sides. Four negative pressure fans 4 are arranged on one bracket 1, with two pairs of them close to the left and right long sides of the fabric to be received. Baffles 5 are installed below the negative pressure fans on the inner side of the two brackets 1.
[0015] Working process: The carrier, pressing down on the pillowcase fabric from the previous process, moves to the transfer table. The third telescopic rod extends, pushing the movable frame from the outside of the table panel towards the top of the outer edge. Then, the first and second telescopic rods extend, pushing the rear end of the vertical rod of the movable frame, causing it to flatten. The pressure plate presses onto the transverse edges S1 and S2 at both ends of the pillowcase fabric, thus securing the pillowcase fabric. Figure 3 As shown.
