Description

Technical Field

[0001] The invention belongs to the technical field of down processing equipment, and in particular relates to a down quilt filling complete set of equipment and a filling method thereof. Background Art

[0002] Currently, the structure of a down quilt is primarily based on sewing the quilt into multiple horizontal and vertical square grids, with openings reserved between the grids for the filling tube to enter and exit. The grids separate and block the down, preventing the down from migrating to other locations. When filling a traditional down quilt, the quilt is first placed in a basket. A manually controlled filling machine is then used to insert the filling tube into the grids of the cup sleeve, filling the grid farthest from the filling port first. Each grid of the quilt shell is then filled in turn. Once all grids are filled, the filling port is closed. However, due to the large number of squares in a down quilt, manual filling requires repeated movement of the quilt, increasing the labor burden. Furthermore, this filling method is inefficient, reducing the efficiency of the down quilt. Furthermore, the down quilt curls and compresses in the basket, making it impossible to distinguish the positions of the quilt grids. This can lead to underfilling and missing filling during manual filling, thus affecting the quality of the down quilt.

[0003] Patent No.: CN201610446380.0, discloses a bed-moving down filling machine, which is mainly composed of a bed frame, a down filling machine, a power device and a control system. In this application, the outlet end of the down filling tube is fixed above the moving bed through a bayonet, and the outlet of the down filling tube extends into the quilt spread on the moving bed to fill the quilt with down. When filling the down, the telescopic threaded tube and the support rod are in the longest state, and the open end of the down filling tube is located in the grid to be filled with down. After the grid is filled, the down quilt is manually pulled to move the down quilt to the next row of grids that need to be filled, and then the down filling machine is started to fill the row of grids with down, and the above process is repeated. Although it has the effect of reducing the labor burden to a certain extent, it still requires manual pulling of the down quilt, and the whole process is still time-consuming and labor-intensive.

[0004] Patent number: CN202210378690.9, discloses a method for filling a down quilt, including a down filling bed and a down filling machine, the down filling machine is provided with multiple down filling tubes, a quilt collecting roller is provided at one end of the down filling bed, a movable frame is provided at the other end of the down filling bed, a material discharging roller is provided on the movable frame, the quilt collecting roller is provided with a material collecting cloth for connecting to one end of the down quilt cover, and the material discharging roller is provided with a material discharging cloth for connecting to the other end of the down quilt cover. This application uses a quilt collecting roller and a material discharging roller to fix the two ends of the quilt during filling, so that the quilt can be rolled up and discharged without manually pulling the down quilt. However, this application requires each down filling tube to be inserted into the filling port of the down quilt in advance before filling the down quilt, and then the two ends of the quilt are fixed. Due to the wide size of the quilt, inserting the quilt tubes one by one is not only time-consuming and labor-intensive, but also prone to the problem of the quilt falling off, affecting the filling efficiency.

The mounting shell 32 is arranged on the outer wall of the filling machine 1, and the fixed tube 34 is horizontally arranged inside the mounting shell 32. The fixed tube 34 is horizontally penetrated and arranged on the side wall of the filling machine 1 and extends into the filling machine 1. The telescopic tube assembly is movably arranged inside the fixed tube 34, and the telescopic tube assembly includes a plurality of sleeves 36 that are sequentially sleeved. Slide grooves 361 are opened on the inner walls of the sleeves 36 and the inner walls of the fixed tube 34 along their length directions, and a slide bar 362 that cooperates with the slide groove 363 is provided on the outer wall of the rear end of the sleeve 36, so as to realize horizontal sliding connection between the sleeves 36 and between the sleeves 36 and the fixed tube 34.

[0044] like Figure 5 As shown, a filling tube assembly is provided in the innermost sleeve 36, and the filling tube assembly includes a movable tube head 37 and a telescopic hose 38. The movable tube head 37 includes a down outlet tube 371, a metal hose 372, and a connecting tube 373. The down outlet tube 371 and the connecting tube 373 are connected by the metal hose 372, so that the movable tube head 37 can move left and right to facilitate insertion into different rows of grids.

[0050] The filling method using the above-mentioned down quilt filling equipment comprises the following steps:

[0051] Step 1: Lay the quilt cover to be filled flat on the quilt-laying table 2, with the filling port 41 of the quilt cover facing the filling machine 1;

[0052] Step 2: Fix both sides of one end of the quilt cover to the winding roller 232 through the first fixing clip 234 respectively, and then control the winding mechanism 23 to wind the quilt cover through the touch display screen 102. After the quilt cover is wound up, a certain length is reserved so that one of the filling openings of the quilt cover corresponds to the position of the movable pipe head 37. At this time, the slider 242 in the pulling mechanism 24 is located at one end close to the winding roller 232, that is, the initial position. Then, the two sides of the other end of the quilt cover are fixed to the slider 242 through the second fixing clip 244 respectively;

[0053] Step 3: Insert the movable tube head 37 into the row of cells closest to the edge of the quilt cover through the filling port, and then control the extension of the telescopic tube assembly through the touch screen 102 to extend the movable tube head 37 into the farthest cell of the quilt cover;

[0054] Step 4: Start the down filling machine 1 so that the down is filled into the cells of the quilt cover through the down filling tube assembly. At the same time, the telescopic tube assembly begins to contract so that the down is filled into each cell of the row in turn. When the down filling machine 1 fills the last cell of the row, the filling stops.

[0055] Step 5: Adjust the movable pipe head 37 so that it is inserted into another row of grids in the quilt cover, and repeat steps 3 and 4 until the last grid in the row is filled;

[0056] Step 6: Take out the movable pipe head 37, control the pulling mechanism 24 to pull the quilt cover through the touch screen 102, and the reeling mechanism 23 unwinds the quilt cover at the same time until the other filling port 41 corresponds to the position of the movable pipe head 37. The unwound quilt cover is in a straight state to facilitate filling. Repeat steps 3 and 4 until the filling machine 1 fills every row of the quilt cover, and the filling machine 1 stops.

[0057] Step 7: Sew each filling opening of the quilt cover, finally loosen the first fixing clip 234 and the second fixing clip 244, remove the quilt cover, and complete the filling process of the duvet cover. The operation is simple and convenient.
