DETAILED DESCRIPTION

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] On the contrary, the present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention as defined by the claims. Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. Those skilled in the art can fully understand the present invention without the description of these details.

[0027] like Figures 1 to 6 The shown device is a feeding and unloading integrated device for a sewing machine, comprising a working panel 1 located at one side of the sewing machine, on which a feeding mechanism 3 and an unloading mechanism 4 are respectively arranged through a first bracket 2. The feeding mechanism 3 comprises a first conveyor belt 5 arranged along the conveying direction of the cloth, and a first driving motor 20 arranged on the working panel 1 for driving the first conveyor belt 5 to rotate, and a first gap 6 for the cloth to pass through is formed between the first conveyor belt 5 and the upper surface of the working panel 1. The number of the first conveyor belts 5 is set to two, corresponding to the head end and the tail end of the first bracket 2 respectively, and a second gap 19 is arranged between the two first conveyor belts 5, and the second gap 19 corresponds to the sewing machine, that is, the first conveyor belt 5 located at the head end of the first bracket 2 sequentially conveys the cloth to be sewn to the sewing machine for sewing, and during the sewing process of the sewing machine, the first conveyor belt 5 located at the head end of the first bracket 2 no longer contacts the cloth, and the cloth sewn by the sewing machine is then conveyed to the unloading mechanism 4 through the first conveyor belt 5 located at the tail end of the first bracket 2 for unloading and collection.

[0028] like Figure 7 and Figure 8As shown, in this embodiment, the first bracket 2 is provided with a rotating shaft 27 corresponding to the two first conveyor belts 5, and a first pulley 28 is provided on the rotating shaft 27. The first conveyor belt 5 is provided between the two corresponding first pulleys 28. The output shaft of the first drive motor 20 is connected to one of the rotating shafts 27. By driving the rotating shaft 27 to rotate, the first pulley 28 is driven to rotate, thereby realizing the transmission of the first conveyor belt 5. A second pulley 29 is also provided on the rotating shaft 27 at the head end and the tail end of the first bracket 2. A third conveyor belt 30 is provided between the second pulleys 29 along the direction of fabric transmission. The third conveyor belt 30 is located on the side of the first conveyor belt 5 away from the sewing machine. On the one hand, the third conveyor belt 30 is used to contact the side of the fabric that does not need to be sewn, and is used to continuously transport the fabric to ensure the flatness of the fabric. On the other hand, the third conveyor belt 30 can realize the connection of the two separated first conveyors 5. Only one first drive motor 20 is required to control the two first conveyors 5 to perform synchronous transmission or pause, which can simplify the structural design of the feeding mechanism 3 and save costs.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, the first bracket 2 is provided with a first sensor 24 connected to the first drive motor 20 by electrical signals. Correspondingly, the number of the first sensors 24 is also set to two, and the installation positions thereof correspond to the positions of the second gaps 19. The sensing head of the first sensor 24 corresponds to the upper surface of the working panel 1. The first sensor 24 senses whether there is cloth on the working panel 1, controls the program output of the first drive motor 20, and ensures the stability and continuity during the cloth feeding process.

[0030] like Figures 1 to 3 As shown, one side of the feeding mechanism 3 is provided with an adjusting mechanism 10 for adjusting the horizontal height of the first bracket 2, that is, the size of the first gap 6, through the second bracket 9. The adjusting mechanism 10 includes a second driving cylinder 11 driven along the longitudinal direction. Through the program output of the second driving cylinder 11, the first bracket 2 can be controlled to drive the feeding mechanism 3 and the unloading mechanism 4 to move upward or downward as a whole, so that when abnormal feeding occurs in the feeding mechanism 3, the feeding process can be suspended manually, and the cloth located at the first gap 6 can be taken or placed.

[0031] Since the output program of the second driving cylinder 11 is fixed, and the first bracket 2, the feeding mechanism 3 and the unloading mechanism 4 are all heavy, the first bracket 2 drives the feeding mechanism 3 and the unloading mechanism 4 to move in the longitudinal direction as a whole in one step. This makes the size of the first gap 6 fixed during the feeding process, and different fabrics have different thicknesses. The size of the first gap 6 needs to be adjusted for fabrics of different thicknesses.

[0032] To solve the above problem, in this embodiment, a piston rod 13 is provided in the cylinder body 12 of the second driving cylinder 11, and the piston rod 13 is rotatably matched with the cylinder body 12. The upper end of the piston rod 13 extends to the outside of the cylinder body 12 and is connected to the rotating handle 14. A connecting shaft 15 is provided at the lower end of the piston rod 13. A connecting hole 16 rotatably matched with the connecting shaft 15 is provided in the first bracket 2. A first thread is provided on the outer surface of the connecting shaft 15, and a second thread corresponding to the first thread is provided on the inner surface of the connecting hole 16.

[0033] With this arrangement, it is only necessary to rotate the rotating handle 14 clockwise or counterclockwise according to the thickness of the cloth, so that the piston rod 13 in the cylinder body 12 of the second driving cylinder 11 drives the connecting shaft 15 to rotate, and the lower end of the connecting shaft 15 drives the first bracket 2 to move upward or downward, thereby adjusting the horizontal height of the first bracket 2 to ensure that the size of the first gap 6 is compatible with the thickness of the cloth to be sewn. There is no need to modify and adjust the output program of the second driving cylinder 11 multiple times, making the sewing of the cloth more time-saving and labor-saving.

[0034] like Figure 1 and Figure 2 As shown, a slide rail 17 is provided on the second bracket 9 along the longitudinal driving direction of the second driving cylinder 11, and a slider 18 is provided on the slide rail 17. The slider 18 is connected to the first bracket 2. This arrangement can improve the accuracy of the first bracket moving in the longitudinal direction on the one hand, and increase the force points of the first bracket during the movement process on the other hand. Since the length of the first bracket 2 is relatively long, in order to ensure the consistency of the height of the two ends of the first bracket, the number of the second bracket 9 is set to two, and the adjustment mechanisms 10 on the two second brackets 9 correspond to the head end and the tail end of the first bracket 2 respectively.

[0035] like Figures 1 to 6 As shown, the unloading mechanism 4 includes a pressing rod 7 and a first driving cylinder 8 for driving the pressing rod 7 to move in the longitudinal direction. The first driving cylinder 8 is arranged at the rear end of the first bracket 2. The pressing rod 7 is connected to the output end of the first driving cylinder 8, and the pressing rod 7 is located below the first bracket 2. A through hole 26 for the pressing rod 7 to pass through is provided in the working panel 1. A second transmission belt 22 is arranged below the pressing rod 7 through the third bracket 21, and a second driving motor 23 for driving the second transmission belt 22 to transmit.

[0036] Driven by the first driving cylinder 8, the pressing rod 7 passes through the through hole 26, and the cloth that has been sewn and transported by the first conveyor belt 5 located at the tail end of the first bracket 2 is pressed down onto the second conveyor belt 22. The output value of the second driving motor 23 is set so that the second conveyor belt 22 moves one end distance every 3 or 4 seconds, so that the cloth can be overlapped in sequence after falling, so as to facilitate collection and sorting.

[0037] like Figure 1 , Figure 3 and Figure 6 As shown, the first bracket 2 is provided with a second sensor 25 connected to the first driving cylinder 8 by electrical signals, the second sensor 25 corresponds to the first conveyor belt 5 located at the rear end of the first bracket 2, and the sensing head of the second sensor 25 corresponds to the upper surface of the working panel 1. The second sensor 25 senses whether there is cloth on the working panel 1, controls the program output of the first driving cylinder 8, and ensures the stability and continuity of the cloth unloading process.

[0038] The above describes the implementation mode of the utility model in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation mode. For ordinary technicians in this field, several modifications and improvements can be made without departing from the present invention, and these should also be regarded as belonging to the protection scope of the present utility model.
