Description

Technical Field

[0001] The present invention relates to the field of home furnishings, and in particular to a packaging method and equipment for a chair iron frame. Background Art

[0002] Among many types of chairs, massage chairs in particular often rely on their internal metal frame to support the overall shape, weight, and user experience. However, to prevent damage to the metal frame during manufacturing and transportation, and to prevent friction between the metal frame and other structural components, the metal frame is typically wrapped with a layer of non-woven fabric to isolate it from other components. This process typically involves manually cutting a roll of non-woven fabric to the desired length, applying glue to one side of the fabric, and then attaching the glued non-woven fabric to the metal frame. This method is not only time-consuming and labor-intensive, but also sometimes results in waste of both fabric and glue.

[0003] Patent document CN110424144A discloses a fully automatic multi-layer cloth laying cutting table, which describes a specific process for automatically cutting non-woven fabrics. Specifically, the cloth on the cloth rack is pulled onto the cutter head from the front end of the cutting platform. The cloth end is placed on the backing plate and aligned with its edge. A push rod on the cutter head then presses down the pressure plate, securing the cloth end when the pressure plate and backing plate meet. After the cloth end is secured, the cloth dragging mechanism extends its jaws as it approaches the cutter head until the jaws move into the groove of the pressure plate, at which point the cloth dragging mechanism stops moving. At this point, one clamping portion of the jaws is located above the cloth end, while the other clamping portion is located below the cloth end. The jaws are then closed, tightening the cloth end. Once the jaws have fully tightened the cloth end, the pressure plate rises, releasing the cloth end, and the cloth dragging mechanism moves toward the rear end of the cutting table. During this movement, the booster mechanism and the cloth dragging mechanism work together to drag the cloth onto the cutting table. When the cloth-pulling mechanism stops at the preset position, the booster mechanism also stops. The pressure plate then descends again, pressing the cloth against the backing plate. The rotating cutter is then activated, and a rodless cylinder on the tool holder drives the cutter from one side of the cloth to the other, completing the cut. A new end of cloth forms on the backing plate at the break. Finally, the clamping jaws release, and the cloth-pulling mechanism moves back toward the tool holder for the next cut.

[0004] In the prior art, in order to allow the cutting table to cut the cloth at the bottom while preventing the cutter from colliding with the cutting table, a groove is provided on the cutting table to allow the cutter to clear the cutter. However, when the cutter is used to cut the cloth, the broken part of the cloth will extend downward into the groove, which may cause the cloth to get stuck when the cloth is mopped. Furthermore, because the clamping jaws need to move behind the cutter when mopping the cloth, the grooves on the cutting table that limit the movement of the clamping jaws and the grooves that allow the cutter to clear the cutter are intersecting. This makes the cross section of the cloth even rougher. In fact, when the clamping jaws are mopping the cloth, the side walls of the groove and the sides of the clamping jaws may even clamp the cross section of the cloth, thus affecting the cutting effect. Summary of the Invention

[0005] In order to solve the problems in the prior art, the purpose of the present invention is to provide a chair iron frame packaging method and equipment, which can effectively protect the cutting tool, avoid fabric cutting edges, avoid fabric jamming, improve the efficiency and consistency of chair iron frame covering, and reduce the waste of fabric and glue.

The top plates 81 can move in and out of the sliding holes 21 in a lifting manner. A first avoidance groove 22 is provided on the panel 2, and a second avoidance groove 82 is provided on both top plates 81. The sliding hole 21 passes through the first avoidance groove 22. The top plate moves up so that the first avoidance groove 22 and the second avoidance groove 82 are both located below the rolling knife 55. The first rubber strip 50 is installed in the first avoidance groove 22, and the fourth rubber strip is installed in the second avoidance groove 82. The steps of packaging the chair iron frame 9 are as follows:

[0052] Step 1) The first pressing plate 42 moves downward to compress the fabric, causing one end of the fabric to extend from under the rolling blade 55 , and then the two clamping jaws move toward the end of the fabric; wherein the upper fingers of the clamping jaws are located above the panel 2 , the lower fingers of the clamping jaws are located below the panel 2 , and the top plate 81 is located below the panel 2;

[0053] Step 2) After the fabric is inserted between the upper finger 744 and the lower finger 743 of the clamping jaws, the lower finger 743 moves upward to clamp the fabric and lift it up; wherein the clamping jaws are located above the top plate 81;

[0063] More preferably, Figure 4As shown, the bottom of the panel 2 is mounted with multiple first travel switches 22, which are arranged left and right. A first trigger is mounted on the first cylinder 741. In step 2), when the first trigger contacts the first travel switch 22 on the left, it indicates that the clamping jaw 74 has reached the first stop position and the fabric has been inserted between the upper finger 744 and the lower finger 743 of the clamping jaw 74, and the clamping jaw 74 then stops moving. In step 4), when the clamping jaw 74 moves to the first stop position, the first trigger on the clamping jaw 74 contacts the corresponding first travel switch 22, and the clamping jaw 74 then stops moving. In step 5), when the first trigger contacts the first travel switch 22 on the right, it indicates that the clamping jaw 74 has moved to the second stop position and stops moving.
