Description

Technical Field

[0001] This utility model relates to the field of down product manufacturing technology, specifically to an automatic down filling and edge-gathering device for down comforters. Background Technology

[0002] Traditional down filling machines lack a fixing device during use. Workers need to manually fix the down products during the filling process. This operation method not only increases the workload of workers, but also requires workers to constantly move and fix the down products in order to ensure the filling effect. After the filling is completed, workers also need to manually fix or sew the filling port.

[0003] For example, the invention patent: a down filling device for down jacket production, publication number: CN119523207A, discloses a down filling device for down jacket production including a storage basket for storing filling material and a transfer component for transferring filling material. The input end of the transfer component is connected to a suction tube for sucking out filling material, and the output end of the transfer component is connected to a delivery tube for conveying filling material. The end of the delivery tube away from the transfer component is connected to a filling nozzle that extends into the fabric.

[0004] This is a relatively traditional down filling device, which requires workers to constantly move the down products. Summary of the Invention

[0005] This invention addresses the issue that traditional down filling devices require manual fixing of the filling port after filling. Instead, it presents an automatic down filling device that automatically trims the edges after filling. This automatic trimming device is compatible with traditional automatic down filling machines while reducing the workload for workers.

[0006] An automatic down filling and edge-gathering device for a down comforter is modified from an existing automatic down filling machine. A down comforter fixing port is set on the shell where the down filling tube of the automatic down filling machine is located. An automatic edge-gathering device and a down comforter filling port fixing device are set inside the automatic down filling machine. The edge-gathering structure of the automatic edge-gathering device is wrapped inside the fixing structure of the down comforter filling port fixing device.

[0007] The filling tube of the automatic down filling machine is connected to the supply port of the automatic down filling machine via a flexible hose;

[0008] The filling tube of the automatic down filling machine is set on the linear telescopic device, passes through the down comforter which is fixed by the down comforter filling port fixer, and goes deep into the filling point inside the down comforter.

[0009] The specific shape of the down comforter's fixing opening is similar to a round hole horizontally superimposed with a rectangle. The round hole is mainly used to fit the down filling tube, while the rectangular part is used to accommodate the deformation of the down comforter. There is a certain extension from the bottom of the filling tube to the edge of the filling opening.

[0010] When using the device of this application, the assembly scheme of the automatic edge trimmer is selected according to the down comforter.

[0011] Regardless of the type of automatic edge trimmer, the down comforter must first be placed on the filling tube, and the filling port of the down comforter must be fixed inside the down comforter fixing port. The automatic edge trimmer and the down comforter filling port fixing device will then secure the down comforter.

[0012] Then the automatic down filling machine begins to fill the down comforter. As the down comforter area is gradually filled, the filling tube automatically retracts into the filling machine, thereby reducing the original manual operation of pulling the down comforter outward.

[0013] Preferably, the automatic edge gatherer includes two symmetrically arranged soft plastic strips, one end of which is fixed to the frame and the other end is connected to a horizontal shrinking mechanism.

[0014] The horizontal retraction mechanism includes: a positioning slide rail, a slider, and a telescopic cylinder; wherein, the telescopic end of the telescopic cylinder is connected to the slider; a soft plastic strip is connected to the slider; and the slider is mounted on the positioning slide rail.

[0015] Circular countersunk holes are set at equal intervals on the inner side of the soft plastic strip. A metal sheet is fixed to the bottom of the countersunk hole, and a magnet is placed inside the countersunk hole.

[0016] The magnet on the upper soft plastic strip works with the magnet on the lower soft plastic strip to tighten the edge of the down filling opening of the comforter.

[0017] The soft plastic strip also features wavy anti-slip textures, which are located on the inside of the soft plastic strip and avoid the down filling tube area.

[0018] The wavy anti-slip texture increases the clamping force on the down comforter as the soft plastic strap transitions from a bridge shape to a straight, parallel shape. When the soft plastic strap is in a straight, parallel shape, the magnetic pieces hidden on the inner side of the strap work together to gather the down comforter. This reduces the need for manual finishing by workers; the comforter can then be automatically sewn onto a sewing machine. The magnets are reusable.

[0019] Preferably, the down comforter filling port retainer includes: two vertically symmetrical clamping blocks, one above the other; wherein the lower clamping block is fixed to the frame.

[0020] A two-degree-of-freedom telescopic device is installed above the upper clamping block;

[0021] The two-degree-of-freedom telescopic device includes: a second horizontal slide rail, a second horizontal telescopic cylinder, a vertical slide rail, and a vertical telescopic cylinder;

[0022] The second horizontal slide rail is fixed to the frame, and the extension end of the second horizontal telescopic cylinder is driven by the slider on the second horizontal slide rail.

[0023] The bottom of the slider on the second horizontal slide rail is equipped with a vertical slide rail and a vertical telescopic cylinder.

[0024] The telescopic end of the vertical telescopic cylinder is driven by the slider of the vertical slide rail; the upper clamping block is fixed to the slider of the vertical slide rail.

[0025] An automatic down filling and edge-gathering device for down comforters.

[0026] The clamping block is arch-shaped;

[0027] A groove is provided on the inner side of the clamping block, which extends from the left end to the right end; the cross-section of the groove is rectangular.

[0028] The two-degree-of-freedom telescopic device not only provides vertical downward pressure to fix the down filling opening of the comforter, but also reserves space for a possible automatic sewing device. The second horizontal slide rail and the second horizontal telescopic cylinder allow for the possibility of setting up the device on a horizontal plane, leaving room for the subsequent development of structures such as automatic sewing needles. This reduces the workload of reassembling the magnetic pieces and further improves the device's sealing performance.

[0029] As a preferred option

[0030] A reference line is drawn from the surface of the body where the down comforter opening is located, which is the center of the down comforter opening.

[0031] A linear telescopic device includes: a horizontal slide rail arranged parallel to a reference line, and a fixing positioning ring on the horizontal slide rail near the end of the down comforter fixing opening, the center of the positioning ring being on the reference line;

[0032] A retaining ring is installed on the slider of the horizontal slide rail. The retaining ring is used to fix the body of the down filling tube.

[0033] A telescopic cylinder is set parallel to the horizontal slide rail. The telescopic cylinder drives the slider of the horizontal slide rail, and at the same time drives the down filling tube to pass through or retract the positioning ring.

[0034] As a preferred embodiment, the linear telescopic device further includes: a bushing device; the bushing device includes: a telescopic collar, a second slider disposed on the horizontal slide rail, and a collar-driven telescopic cylinder;

[0035] The telescopic collar is divided into two sections. The outer diameter of the first section matches the inner diameter of the positioning ring, and the outer diameter of the second section is the same as the outer diameter of the positioning ring. The inner diameters of the two sections of the telescopic collar are the same and are both larger than the outer diameter of the filling tube. The telescopic collar is set on the second slider, and the first section of the telescopic collar penetrates the positioning ring.

[0036] The collar-driven telescopic cylinder is set parallel to the horizontal slide rail, and the telescopic end drives the second slider.

[0037] This preferred solution can be used for down comforters with pre-embedded thermally spun fabric. The automatic edge-gathering device includes two symmetrically arranged elastic metal strips, one end of which is fixed to the frame, and the other end is connected to a horizontal shrinking mechanism. The horizontal shrinking mechanism includes a positioning slide rail, a slider, and a telescopic cylinder. The telescopic end of the telescopic cylinder is connected to the slider; the elastic metal strip is connected to the slider; the slider is mounted on the positioning slide rail; and a heating wire is attached to the elastic metal strip. While the automatic edge-gathering device gathers the edges of the down comforter, the heating wire simultaneously bonds the thermally spun fabric, thus completing a fully automated edge-gathering operation.

[0038] The inner sides of both ends of the elastic metal strip are also provided with wavy anti-slip textures, which avoid the area of ​​the down filling tube.

[0039] The beneficial effects of this invention are as follows: it can automatically shrink the filling tube according to the stage of filling, eliminating some of the labor required by workers. It can automatically close the opening of the filled down comforter, reducing the need for workers to manually close the filling opening after filling. Furthermore, placing the filling opening entirely within the machine body also helps reduce the environmental impact of down overflowing from the filling opening during filling.

Detailed Implementation

[0046] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example 1

[0047] like Figure 1 and Figure 3As shown, the automatic down filling and edge-gathering device for down comforters is modified from an existing automatic down filling machine. A down comforter fixing port 10 is set on the shell where the down filling tube of the automatic down filling machine is located. An automatic edge-gathering device and a down comforter filling port fixing device are set inside the automatic down filling machine. The edge-gathering structure of the automatic edge-gathering device is wrapped inside the fixing structure of the down comforter filling port fixing device.

[0048] The filling tube of the automatic down filling machine is connected to the supply port of the automatic down filling machine via a flexible hose;

[0049] The filling tube of the automatic down filling machine is set on the linear telescopic device, passes through the down comforter which is fixed by the down comforter filling port fixer, and goes deep into the filling point inside the down comforter.

[0050] The specific shape of the down comforter fixing opening 10 is similar to a round hole with a rectangle superimposed on it. The round hole part is mainly used to fit the down filling tube b, while the rectangular part is used to adapt to the deformation of the down comforter a. There is a certain extension when it is stretched from the bottom of the down filling tube b to the edge of the down filling opening.

[0051] When using the device of this application, the assembly scheme of the automatic edge trimmer is selected according to the down comforter.

[0052] Regardless of the type of automatic edge-sealing device, the down comforter (a) must first be placed over the filling tube (b) (e.g.) Figure 2 As shown in the figure, the down filling port of the down comforter is fixed to the down comforter fixing port, and the down comforter is fixed by the automatic edge gatherer and the down filling port fixing device.

[0053] Then the automatic down filling machine begins to fill the down comforter. As the down comforter area is gradually filled, the filling tube automatically retracts into the filling machine, thereby reducing the original manual operation of pulling the down comforter outward.

[0054] like Figure 4 The automatic edge-shrinking device shown includes two symmetrically arranged soft plastic strips 6, one end of which is fixed to the frame and the other end is connected to a horizontal shrinking mechanism.

[0055] The horizontal retraction mechanism includes: a positioning slide rail 8, a slider, and a telescopic cylinder 9; wherein, the telescopic end of the telescopic cylinder is connected to the slider; a soft plastic strip is connected to the slider; and the slider is mounted on the positioning slide rail.

[0056] Circular countersunk holes are set at equal intervals on the inner side of the soft plastic strip. A metal sheet is fixed to the bottom of the countersunk hole, and a magnet is placed inside the countersunk hole.

[0057] The magnet on the upper soft plastic strip works with the magnet on the lower soft plastic strip to tighten the edge of the down filling opening of the comforter.

[0058] The soft plastic strip also features wavy anti-slip textures, which are located on the inside of the soft plastic strip and avoid the down filling tube area.

[0059] The wavy anti-slip texture increases the clamping force on the down comforter as the soft plastic strap transitions from a bridge shape to a straight, parallel shape. When the soft plastic strap is in a straight, parallel shape, the magnetic pieces hidden on the inner side of the strap work together to gather the down comforter. This reduces the need for manual finishing by workers; the comforter can then be automatically sewn onto a sewing machine. The magnets are reusable.

[0060] The down comforter filling port fixing device includes: two vertically symmetrical pressing blocks 1; wherein the lower pressing block is fixed to the frame;

[0061] A two-degree-of-freedom telescopic device is installed above the upper clamping block;

[0062] The two-degree-of-freedom telescopic device includes: a second horizontal slide rail 4, a second horizontal telescopic cylinder 5, a vertical slide rail 3, and a vertical telescopic cylinder 2;

[0063] The second horizontal slide rail is fixed to the frame, and the extension end of the second horizontal telescopic cylinder is driven by the slider on the second horizontal slide rail.

[0064] The bottom of the slider on the second horizontal slide rail is equipped with a vertical slide rail and a vertical telescopic cylinder.

[0065] The telescopic end of the vertical telescopic cylinder is driven by the slider of the vertical slide rail; the upper clamping block is fixed to the slider of the vertical slide rail.

[0066] An automatic down filling and edge-gathering device for down comforters.

[0067] The clamping block is arch-shaped;

[0068] A groove is provided on the inner side of the clamping block, which extends from the left end to the right end; the cross-section of the groove is rectangular.

[0069] The two-degree-of-freedom telescopic device not only provides vertical downward pressure to fix the down filling opening of the comforter, but also reserves space for a possible automatic sewing device. The second horizontal slide rail and the second horizontal telescopic cylinder allow for the possibility of setting up the device on a horizontal plane, leaving room for the subsequent development of structures such as automatic sewing needles. This reduces the workload of reassembling the magnetic pieces and further improves the device's sealing performance.

[0070] A reference line is drawn perpendicular to the center of the down comforter opening from the surface of the garment where the comforter opening is located; for example, Figure 5 As shown: The linear telescopic device includes: a horizontal slide rail arranged parallel to the reference line, and a fixed positioning ring 11 on the horizontal slide rail close to the fixing opening of the down comforter, with the center of the positioning ring on the reference line;

[0071] A retaining ring 12 is provided on the slider of the horizontal slide rail. The retaining ring is used to fix the tube body of the down filling tube b.

[0072] A telescopic cylinder 13 is set parallel to the horizontal slide rail. The telescopic cylinder drives the slider of the horizontal slide rail, and at the same time drives the filling tube to pass through or retract the positioning ring.

[0073] The linear telescopic device also includes: a bushing device; the bushing device includes: a telescopic collar 7, a second slider set on the horizontal slide rail, and a collar-driven telescopic cylinder 14;

[0074] The telescopic collar is divided into two sections. The outer diameter of the first section matches the inner diameter of the positioning ring, and the outer diameter of the second section is the same as the outer diameter of the positioning ring. The inner diameters of the two sections of the telescopic collar are the same and are both larger than the outer diameter of the filling tube. The telescopic collar is set on the second slider, and the first section of the telescopic collar penetrates the positioning ring.

[0075] The collar-driven telescopic cylinder is set parallel to the horizontal slide rail, and the telescopic end drives the second slider. Example 2

[0076] This solution can be used for down comforters with pre-embedded thermally spun fabric. Unlike the automatic edge-gathering device in Example 1, the automatic edge-gathering device in this embodiment includes two symmetrically arranged elastic metal strips, one end of which is fixed to the frame, and the other end is connected to a horizontal shrinking mechanism. The horizontal shrinking mechanism includes a positioning slide rail, a slider, and a telescopic cylinder. The telescopic end of the telescopic cylinder is connected to the slider; the elastic metal strip is connected to the slider; the slider is mounted on the positioning slide rail; and heating wires are attached to the elastic metal strips. While the automatic edge-gathering device gathers the edges of the down comforter, the heating wires simultaneously bond the thermally spun fabric, thus completing a fully automated edge-gathering operation.

[0077] The inner sides of both ends of the elastic metal strip are also provided with wavy anti-slip textures, which avoid the area of ​​the down filling tube.
