[0015] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0016] A digital printing machine, such as Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, it includes a machine body 1 and a rotating table 2 fixed in the middle by bolts. There are four processing rollers 3 in a circular array on the outer peripheral wall of the rotating table 2. The processing rollers 3 rotate counterclockwise around the rotating table 2 under the drive of the rotating table 2. A printing device is slidably connected to one side of the machine body 1, and the printing device slides along the length direction of the machine body 1. A conveying table 4, a placement table 5 and a removal table 6 with the same relative positions as the several processing rollers 3 are respectively provided on the machine body 1. Therefore, the four processing rollers 3 correspond to the conveying table 4, the placement table 5 and the printing device, respectively, so that the several processing rollers 3 can process the socks at the same time. Therefore, workers do not need to stand in front of the equipment for a long time to put the socks on the processing rollers 3 and remove the processed socks from the processing rollers 3, thereby reducing the labor and time costs when using the equipment.

[0017] like Figure 1 、 Figure 2 and Figure 4As shown, a number of socks are placed on the conveying table 4, and a number of socks to be printed can move forward with the conveying table 4. The conveying table 4 is fixedly connected to an electric track 7 which is arranged along the width direction of the conveying table 4 and has the same relative position as the processing roller 3. The electric track 7 is slidably connected to a stretching part. The electric track 7 is arranged along the width direction of the machine body 1, so the stretching part can drive the socks to be put on the processing roller 3. The stretching part includes a sliding table 12 slidably connected to the electric track 7 and an electric track 3 13 arranged in the width direction of the sliding table 12. The electric track 3 13 is slidably connected to two stretching rods 14 that are against the open ends of the socks. The two stretching rods 14 can slide towards or away from each other on the electric track 3 13 at the same time. In the initial state, the distance between adjacent stretching rods 14 is less than the straight line of the processing roller 3. The diameter of the socks is such that the two stretching rods 14 can stably slide into the unstretched socks. The sides of the two stretching rods 14 that are close to each other are fixedly connected with an air outlet pipe 15 through a strap. When the stretching rods 14 are extended into the socks, they are driven by the electric track three 13 to move away from each other so that the distance between the two stretching rods 14 is greater than the diameter of the processing roller 3. At this time, the air outlet pipe 15 is started to increase the amount of air inside the socks, thereby increasing the cross-sectional area of ​​the socks, so that the socks can be better fitted on the processing roller 3 through the stretching rods 14. Preferably, the two air outlet pipes 15 are staggered, one is located at the end of the stretching rod 14 close to the ground, and the other is located at the end of the stretching rod 14 away from the ground. By setting the positions of several air outlet pipes 15 and coordinating with the stretching rods 14, the width and height of the socks are increased at the same time, so that the socks can better slide into the processing roller 3.

[0018] like Figure 1 、 Figure 2 and Figure 4As shown, a support frame 16 with an L-shaped cross-section is fixed to the side wall of the conveying platform 4 by bolts, a telescopic rod 1 is fixed to the bottom surface of the support frame 16, and an adsorption plate 17 is fixed to the end of the telescopic rod 1 away from the support frame 16. The telescopic rod 1 is set as an electric telescopic rod. There is suction force that can adsorb socks at every interval on the surface of the conveying platform 4, which ensures the stable fixation of the socks during the conveying process. An optical fiber sensor is set on the bottom surface of the support frame 16, and a receiver for receiving signals is set on the top surface of the conveying platform 4. When the socks move to the bottom of the support frame 16, the socks cut off the optical signal transmission between the sensor and the receiver. The length of the telescopic rod 1 is increased until the adsorption plate 17 contacts the surface of the sock and adsorbs it. At this time, the length of the telescopic rod 1 is shortened so that it drives one side of the sock to move upward a short distance. Since the other side of the sock is adsorbed on the surface of the conveying platform 4, there is a channel inside the sock for the expansion rod 14 to pass through. The bottom surface of the expansion rod 14 is fixedly connected to a raising block slidably connected to the electric track 3 13. Through the setting of the raising block, the bottom surface of the expansion rod 14 is located on the bottom surface of the processing roller 3, so that the inner bottom surface of the sock can contact the bottom surface of the processing roller 3, ensuring the stable installation of the sock on the processing roller 3.

[0019] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, a sliding rod 18 is fixedly connected to the top surface of the body 1, and the positioning member 8 is configured as a laser head 19 slidably connected to the sliding rod 18. A connecting rod 20 is welded to one end of the opening rod 14 close to the body 1, and the other end of the connecting rod 20 is welded to the positioning member 8. In the initial state, the opening rod 14 is located at a section of the electric track 7 close to the body 1. When the sock moves to the bottom of the adsorption plate 17, the opening rod 14 moves in the direction close to the sock under the drive of the sliding platform 12 and completes the extension into the sock. At this time, the outer peripheral wall of the opening end of the sock It is located on the same plane as the end of the stretching rod 14 close to the body 1, thereby ensuring that the positioning member 8 accurately positions the length of the socks. When the socks are placed on the processing roller 3, the sliding table 12 drives the stretching rod 14 and the positioning member 8 to move together in the direction close to the body 1 until the end of the processing roller 3 away from the body 1 is against the inner wall of the socks. At this time, the positioning member 8 moving with the stretching rod 14 can accurately and quickly determine the length of the socks, allowing the printing equipment to complete the printing work on the socks according to the length of the socks, thereby improving the processing efficiency of the equipment.

[0020] like Figure 1 、 Figure 3 and Figure 4As shown, the placement table 5 is provided with several padding papers 9 that are against the processing roller 3. Several padding papers 9 are placed on the placement table 5 in sequence. When one padding paper 9 is wound and fixed on the processing roller 3, another padding paper 9 will move forward on the placement table 5 and move again to the bottom of the processing roller 3. One end of the padding paper 9 is located in the same vertical plane as the central axis of the processing roller 3 in the height direction. The padding paper 9 is fixed to the outer peripheral wall of the processing roller 3 by electrostatic winding. There is a suction force on the side of the processing roller 3 close to the ground that can absorb the padding paper 9, which ensures the stable fixation of the padding paper 9 on the processing roller 3. The placement position of the padding paper 9 and the processing roller 3 is set to reduce the situation where the end of the padding paper 9 that is not fixed is folded when the processing roller 3 rotates due to one side of the padding paper 9 not being absorbed. The length of the padding paper 9 is the same as the length of the processing roller 3 and is smaller than the length of the socks. During the printing process of the socks, the length of the printing setting movement is usually greater than the length of the socks. The integrity of the printing on the socks is ensured by increasing the printing margin, and the setting of the padding paper 9 allows the excess printing to be printed on the padding paper 9 instead of the processing roller 3.

[0021] like Figure 1 and Figure 4 As shown, a glue coating plate 21 is slidably connected to the inner top surface of the machine body 1, and the glue coating plate 21 is located on the side of the pad paper 9 away from the processing roller 3. Glue exists on the glue coating plate 21 for a long time, and the glue coating plate 21 is fixed to the inner top surface of the machine body 1 by the telescopic rod 2. When one end of the pad paper 9 is located below the processing roller 3, the length of the telescopic rod 2 increases so that the bottom surface of the glue coating plate 21 is against the end of the pad paper 9 away from the processing roller 3, thereby coating the glue on the end of the pad paper 9. When the processing roller 3 rotates, one end of the pad paper 9 will be electrostatically adsorbed on the processing roller 3. As the processing roller 3 rotates, the end of the pad paper 9 coated with glue will rotate until it is against the outer peripheral wall of the pad paper 9. At this time, the pad paper 9 is fixed, and due to the stable adsorption force between the outer peripheral wall of the processing roller 3 and the pad paper 9, the situation in which the sock moves upward with the pad paper 9 due to the friction exerted by the sock on the pad paper 9 during the process of being put on the processing roller 3 is reduced.

[0022] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the take-out table 6 is provided with an electric track 2 10, which slides along the width direction of the machine body 1. The electric track 2 10 is slidably connected to a sock-taking portion that abuts against the processing roller 3. The sock-taking portion includes a slider 22 slidably connected to the electric track 2 10 and a sock-taking block 23 integrally formed with the slider 22. The cross-section of the sock-taking block 23 is arc-shaped and its opening faces the processing roller 3. When the processing roller 3 drives the processed socks to rotate above the take-out table 6, the outer peripheral wall of the socks mounted on the processing roller 3 will abut against the outer peripheral wall of the sock-taking block 23. In the initial state, the sock-taking block 23 is located at one end of the sock near the sock opening, and the slider 22 has a large supporting force on the sock-taking block 23. The impact force of the processing roller 3 on the sock taking block 23 ensures that the sock taking block 23 is stably fixed in the electric track 2 10. The inner wall of the sock taking block 23 has an adsorption force that can fix the socks. A collection box 1 24 for storing socks is placed on the side of the taking-out platform 6 away from the machine body 1. The sock taking block 23 moves along the electric track 2 10 in a direction away from the machine body 1. At this time, the sock taking block 23 drives the socks to slide together under the action of its own adsorption force, thereby taking the socks off the processing roller 3. When the sock taking block 23 moves to the end of the electric track 2 10 farthest from the machine body 1, the suction force of the sock taking block 23 on the socks disappears. At this time, the socks will fall into the collection box 1 24 under the action of their own gravity.

[0023] like Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the end of the sock-taking part close to the machine body 1 is fixedly connected with a cutting knife 11 that abuts against the processing roller 3. The cutting knife 11 is welded to the side of the sock-taking block 23 close to the machine body 1. A movable space is formed between the cutting knife 11 and the sock-taking block 23. Since the sock-taking block 23 abuts against the sock, the movable space is set to avoid direct contact between the cutting knife 11 and the sock. The hardness of the cutting knife 11 is less than that of the processing roller 3, thereby reducing the situation where the cutting knife 11 contacts the sock and damages the sock. The bottom surface of the taking-out table 6 is provided with a collecting box 25 for storing the padding paper 9. The movement of the sock-taking block 23 will move downward with the cutting knife 11. In the process of the sock being removed from the processing roller 3, the cutting knife 11 will move together with the sock-taking block 23, and abut against the padding paper 9 during the sliding process, thereby cutting the padding paper 9 and causing it to fall off the processing roller 3. A support plate is provided on one side of the second 25, and a pressing piece is provided on the support plate. The pressing piece includes a receiving rod provided on the support plate and a pressing plate provided perpendicular to the supporting rod. The pressing plate can rotate 360 ​​degrees on the receiving rod by rotating the ball. The side of the pressing plate close to the processing roller 3 is set to an arc shape. The rotation of the pressing plate is controlled by the control panel. When the cutting knife 11 cuts the pad paper 9, the pad paper 9 will fall on the electric track 2 10 under the action of its own gravity. The pressing plate is driven to rotate by the control panel, thereby pressing the pad paper 9 fallen on the electric track 2 10 downward and causing it to fall into the collection box 2 25. Due to the different lengths of the socks, different lengths will cause excess printing to be left at different positions of the pad paper 9. When the socks are placed on the pad paper 9 that has not been replaced for a long time, the surface of the socks will be raised under the action of printing, affecting the printing quality.

[0024] Working principle: When the equipment is not in use, the four processing rollers 3 are respectively located below the printing equipment, above the conveying table 4, the placing table 5 and the taking-out table 6. When printing processing is required, the processing roller 3 is first located above the placing table 5, and the processing roller 3 is rotated to first electrostatically adsorb the padding paper 9 on the processing roller 3, and then the processing roller 3 with the padding paper 9 fixed is rotated to above the conveying table 4 by the rotating table 2, and the socks are placed on the processing roller 3 by sliding the spreader rod 14. The sliding of the spreader rod 14 will drive the movement of the positioning part 8, thereby determining the length of the socks to be printed, and the processing roller 3 is rotated again to move it to the bottom of the printing equipment for printing. The printed socks are driven by the processing roller 3 to move to the bottom of the taking-out table 6, and the socks are removed from the processing roller 3 while the padding paper 9 is cut by the sock taking block 23 and the cutting knife 11. Finally, the cut padding paper 9 is placed in the collection box 2 25 by the pressing plate, thereby completing the complete printing of the socks.
