Description
Technical Field
[0001] The invention belongs to the technical field of sofa production, in particular to a production system and a production process of a simulated leather gold-stamping sofa. Background Art
[0002] The general structure of a modern sofa (from bottom to top): frame - elastic band - bottom gauze - sponge - inner bag - outer cover. In the existing technology, according to the principle of professional division of labor and improving work efficiency, sofa processing is divided into 5 sections: frame section, mainly making sofa frames; exterior section, mainly making exposed components of sofas; lining section, preparing various sponge inner cores; outer cover section, cutting and sewing outer covers; general assembly (leathering) section, assembling the semi-finished products of each section with auxiliary materials into a complete sofa product.
[0003] For example, a Chinese patent with application number CN201510973859.5 discloses a production process for manufacturing sofas, and the specific steps are as follows: 1) ingredients; 2) finishing treatment: place the plates, bent parts and square materials in step 1) on a grinding device for surface grinding to remove burrs and sharp angles on the surface of the plates; 3) assembling the frame; 4) preparing sponges; 5) configuring sofa inner cushions: fill the inner cushion shell of the sofa with a certain amount of sponges through a sponge filling machine and a quantitative mechanism; 6) pasting the frame; 7) cutting the outer cover; 8) assembly (touch the leather).
[0004] In this scheme, in the frame section, the surface of the plate of the selected frame is polished by a grinding device to remove burrs and sharp angles on the surface of the plate; in the lining section, the quantitative mechanism can ensure that the amount of sponge filled in the sofa cushion is the same each time, eliminating the need for test correction and filling of each sofa cushion to adjust the fullness of the sofa; in the final assembly (leather touching) section, the operator can quickly turn the sofa 360° and change different angles of the workstation through the leather touching device, but this scheme does not consider the inconvenience of using the existing elastic band automatic tensioning machine: 1. Most of the existing elastic band automatic tensioning machines need to use different elastic band fixing devices for elastic bands of different widths, which is not convenient for loading and unloading of elastic bands, and thus it is difficult to apply to elastic bands of various widths, thereby affecting the sofa production efficiency; 2. The size is large, the structure is complex, it is inconvenient to move, the working area is small and the working range is limited; 3. There is a lack of automatic cutting device, and the elastic band needs to be cut manually, which increases the workload of personnel and has low work efficiency.
[0005] In view of this, the present invention proposes a production system and a production process of a simulated leather gold-stamping sofa, which solves the above technical problems. Summary of the invention

The manual processing has low efficiency and is difficult to adapt to mass production. In addition, the tension of the elastic bands is difficult to control, which makes it difficult to ensure the quality of the sofa. Semi-automatic auxiliary processing generally uses an elastic band automatic tensioning machine for processing. However, most existing elastic band automatic tensioning machines require different elastic band fixing devices for elastic bands of different widths, which is inconvenient for loading and unloading of elastic bands, and thus is difficult to apply to elastic bands of various widths, thereby affecting the production efficiency of the sofa.

The rolling elements of the holder and the support seat are in contact with the shaft, which facilitates the rotation of the shaft between the holder and the support seat. Then the elastic band is passed through the active roller and the pressure roller. After the elastic band is fixed, the controller drives the motor to rotate forward, and the active roller rotates forward accordingly. The elastic band is pulled out, and after it is pulled to an appropriate length, the staff fixes one end of the elastic band, and the controller drives the motor to reverse and tighten the elastic band.

When the piston rod of the first cylinder contracts and pushes the paddle plate, the paddle plate pushes the support shaft of the clamping roller from one end of the arc groove to the other end, so that the distance between the clamping roller and the active roller becomes smaller, thereby pressing the elastic band on the surface of the active roller, and controlling the rotation direction of the motor is convenient for automatic unloading or tensioning of the elastic band, thereby facilitating the use of different unloading methods according to work needs and improving work efficiency.
