Before sewing, the operator first wraps the decorative fabric at the front end around the decorative core and moves it to the sewing machine 41. Since the sewing machine 41 moves along the driving mechanism 3, the subsequent decorative fabric and the decorative core will be under the action of the guiding and fitting assembly 42, so that the decorative fabric wraps around the decorative core and is sent to the sewing machine 41 for sewing with the fabric cover / mattress.

[0043] In this embodiment, the driving mechanism 3 includes at least one slide rail 31 and a driving groove 32. The mounting plate 33 is arranged between the slide rails 31. A driving device is provided on the driving groove 32, and the driving device is connected to the mounting plate 33 through a connecting member to control the movement of the mounting plate 33. Specifically, the sewing device 4 is fixedly installed on the mounting plate 33. When the driving device moves, the mounting plate 33 is driven to move through the connecting member connected to the mounting plate 33. Since the sewing device 4 is installed on the mounting plate 33, when the mounting plate 33 moves along the slide rail 31, the sewing device 4 moves along with it. At this time, the sewing machine 41 works synchronously, so that the sewing device 4 performs sewing work along the edge of the operating table 1, and thus the decorative strip can be sewn on the fabric cover / mattress without manual intervention.

[0044] Preferably, the driving mechanism 3 includes but is not limited to a motor, a transmission shaft, gears, chains, etc.

[0045] In this embodiment, a pneumatic control pressing member 4101 is provided at the sewing head of the sewing machine 41 to enhance the fitting degree among the decorative core, the decorative fabric and the fabric cover or mattress, reduce the possibility of material displacement during the sewing process, and further improve the sewing effect.

[0046] In this embodiment, a number of control buttons 5 are further provided at both ends of the operating table 1. Specifically, the control buttons 5 are used to control the movement of the lifting cylinder 2102 and the telescopic cylinder 2104, the movement degree of the displacement baffle 22, and the on / off states of various components. During the sewing process of this equipment, only by adjusting the control buttons 5 can the fixing degree of the fabric cover / mattress by the fixing mechanism 2 be controlled, without manual adjustment. In addition, the operator can operate while standing at one end of the operating table 1, which is more convenient, saves time and improves efficiency.

[0047] The working process of the automatic sewing equipment for the decorative strip of the utility model is as follows: Place the sewing thread on the bracket 43, and place the decorative cloth and the decorative core at the guiding and fitting component 42. Specifically, place the decorative cloth on the tray 4201, and pass the decorative core through the guiding hole 4202. Further, the staff manually connects the sewing thread to the sewing machine 41, wraps the outermost decorative cloth around the decorative core and presses it under the pneumatic control pressing part 4101 of the sewing machine 41. Further, in the application scenario of sewing the decorative strip on the cloth cover, the staff needs to place the cloth cover on the operating table 1, fit the edge to be sewn to the edge of the operating table 1, and press it with the fixing part 21. Among them, the lifting cylinder 2102 and the telescopic cylinder 2104 can be adjusted to adapt to cloth covers of different thicknesses, and the pressing effect is better; if it is in the application scenario of sewing the decorative strip on the mattress, place the mattress on the side on the operating table 1, and telescopically adjust the displacement baffle 22 to better fix the mattress and prevent the mattress from shifting. When sewing the decorative strip, start the driving mechanism 3 and the sewing device 4. The driving device moves along the driving groove 32 and drives the mounting plate 33 to move along the slide rail 31 through the connecting piece. The sewing device 4 is fixed on the mounting plate 33, so that the sewing device 4 moves driven by the driving mechanism. And, the sewing machine 41 works synchronously, and continuously feeds materials from the bracket 43 and the guiding and fitting component 42. The staff manually wraps the outermost decorative cloth around the decorative core and connects it to the sewing machine 41. The guiding and fitting component 42 sends the subsequent decorative cloth wrapped around the decorative core to the sewing machine 41. In the traditional technology, the process of sewing the decorative strip on the cloth cover / mattress usually requires two steps. The first step is to wrap the decorative cloth around the decorative core to form the decorative strip, and the second step is to sew the decorative strip to the edge of the cloth cover / mattress. This method requires multiple steps to complete production, has low efficiency, and is difficult to meet the production volume requirements. The automatic sewing equipment for the decorative strip of the utility model combines the above steps to be completed on one device, improving the production efficiency.
