[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0028] See Figures 1-8 The double-cutting machine feeding mechanism includes a turntable unit 1 and a feeding machine 2.

[0029] The turntable unit 1 includes a first drive unit, a turntable 11 driven by the first drive unit to rotate, and several turntable fixtures 6 mounted on the turntable 11. As one option, the first drive unit and the turntable 11 can be hydraulic turntables. Of course, the first drive unit can also be a motor, which drives the turntable 11 to rotate. To make the turntable unit more aesthetically pleasing, a housing 12 can be further provided to hide the first drive unit inside. The turntable 11 is arranged above the housing 12. The housing 12 must be designed to ensure that it does not affect the normal rotation of the turntable.

[0030] As one embodiment, it also includes a base 13, on which the bottom of the turntable unit 1 is mounted. For example, the outer casing 12 or the first drive unit is mounted on the base 13. Furthermore, it can be mounted in the middle position of the base 13 to reserve space on the base 13 for mounting other devices.

[0031] In this embodiment, four turntable fixtures 6 are installed on the upper side of the turntable 11. The four turntable fixtures 6 are evenly distributed so that when the turntable 11 rotates a quarter circumference angle (90 degrees), the turntable fixtures 6 can accurately move to the next process step. As for how to control the turntable to stop after rotating a quarter circumference angle and to restart rotating a quarter circumference angle after the corresponding workstation is completed, the electrical control method can refer to existing designs, such as designing relevant sensors, controllers, etc.

[0032] like Figure 1 As shown, the feeding machine 2 is arranged at station one, the double-sided cutting unit 3 is arranged at station two, the single-sided cutting unit is arranged at station three, the material rolling mechanism is arranged at station four, and the four turntable fixtures 6 correspond to the corresponding stations. After the turntable fixture 6 takes the material from the feeding machine 2 rotates one movement (90 degrees), the turntable fixture 6 stops at station two, and so on.

[0033] For turntable fixture 6, such as Figure 7As shown, it includes a turntable fixture housing 61 and a clamping unit mounted on the turntable fixture housing 61. Specifically, the clamping unit includes a first chuck 62 fixed to the turntable fixture housing 61 and a second chuck 63 slidably disposed on the turntable fixture housing 61. The second chuck 63 is controlled by a driving member disposed on the turntable fixture housing 61 to control its longitudinal movement. As one option, the driving member can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, an oil cylinder, etc. The driving member can be specifically mounted on... Figure 7 The location shown is point A.

[0034] The second chuck 63 can be mounted on the slider, which is slidably connected to the slide rail. Two slide rails can be arranged longitudinally and are parallel to each other. The slide rails are fixed to the inner wall of the turntable fixture housing 61, thereby realizing the sliding connection of the second chuck 63.

[0035] In this embodiment, the clamping surface of the outer end of the first chuck 62 is adapted to the shape of the lower surface of the material, and the clamping surface of the outer end of the second chuck 63 is adapted to the shape of the upper surface of the material, so as to improve the clamping firmness of the material and not damage the material surface.

[0036] In this embodiment, as Figure 6 As shown, the outer side plate 611 of the turntable fixture housing 61 is provided with a through hole 612 for the outer ends of the first chuck 62 and the second chuck 63 to extend to the outside of the turntable fixture housing. The through hole 612 is reserved with space for the second chuck 63 to move longitudinally. Thus, while hiding most of the internal structure of the turntable fixture housing 61, the normal operation of the turntable fixture is not affected.

[0037] For feeder 2, such as Figure 1-5 As shown, it includes a first support 21. A drive roller 221 and a driven roller 222 are respectively installed at the front and rear ends of the upper part of the first support 21. A conveyor belt 223 for transporting materials is wound around the drive roller 221 and the driven roller 222. The drive roller 221 is driven by a motor, which can be fixed to the first support 21, such as on one of its legs, so that the motor drives the drive roller 221 to rotate, thereby driving the conveyor belt 223 to circulate. For controlling how to stop the conveyor belt after it has traveled a certain distance and then continue forward a certain distance after the first row of materials has been pushed, existing designs can be referenced, such as designing relevant sensors and controllers.

[0038] As one implementation method, such as Figure 2 As shown, materials are arranged row by row from front to back, with each row containing multiple materials. After all the materials in front have been pushed, workers can replenish materials from behind conveyor belt 223 when it is stopped, or by using a material tray. Figure 2 All materials shown are placed on conveyor belt 223 at once.

[0039] In this embodiment, the first support 21 is also provided with a feeding unit, which includes a first feeding unit and a second feeding unit. The first feeding unit is used to push the first row of materials to move laterally and push the materials one by one to the second feeding unit. Then, the second feeding unit feeds them into the clamping unit of the turntable fixture, where the clamping unit clamps them and sends them to the next workstation for processing.

[0040] Specifically, the first feeding unit includes a sixth drive unit 22, a ball screw 23 connected to the sixth drive unit 22, and a first pusher 24 mounted on the nut of the ball screw. The sixth drive unit 22 can be a servo motor, which is mounted on the first bracket 21. Specifically, a fixing member can be fixed on the upper part of the first bracket 21, and the servo motor can be fixed on the fixing member. The two ends of the ball screw 23 are rotatably mounted on the first bracket 21. Specifically, a fixing member can be fixed at both ends of the upper part of the first bracket 21, and the two ends of the ball screw 23 are rotatably mounted on the corresponding fixing member. Of course, bearings can be added at the rotatable connection.

[0041] The first pusher 24 is fixed to the nut of the ball screw. Furthermore, two guide posts 251 are fixed to the fixing member. The two ends of each guide post 251 are fixed to a corresponding fixing member. A guide sleeve 252 is slidably mounted on each guide post 251. The first pusher 24 is fixed to the guide sleeve 252. After the sixth drive unit 22 drives the screw to rotate, the screw nut moves laterally, causing the first pusher 24 to move laterally. In the initial stage, the lower end of the first pusher 24 is located on the right side of the first row of materials (within the first row). Figure 2 (At a mid-angle), after the first pusher 24 moves laterally, it can push the first row of materials to the left until the leftmost material enters the second feeding unit. Then, the sixth drive unit 22 stops operating and restarts when the next material needs to be conveyed. For how to control the start and stop of the sixth drive unit, existing designs can be referenced, such as designing relevant sensors and controllers.

[0042] For the response after the first pusher 24 has pushed a row of materials, existing designs can be referenced, such as using a forward and reverse motor or a bidirectional screw structure.

[0043] The second feeding unit includes a seventh drive unit 26, a second pusher 27 driven by the seventh drive unit 26 to move back and forth, and a feeding channel 28 arranged on the travel path of the second pusher 27. The seventh drive unit 26 can be a cylinder, and its cylinder rod is connected to the second pusher 27. The second pusher 27 is slidably mounted on the first bracket 21. For example, the second pusher 27 is fixed on the slider, the slide rail is fixed on the first bracket 21, and the slider is slidably connected to the slide rail.

[0044] like Figure 1 , Figure 2 , Figure 4 As shown, the feeding channel is composed of two spaced baffles 281. Its discharge end corresponds to the clamping unit of the turntable fixture 6, and its feed end is reserved with a notch 282 for the material on the conveyor belt to enter. The notch 282 can be formed by shortening the length of the baffle 281 at that point. That is, the first row of material and the notch 282 are on the same straight line so that after the first row of material is pushed to move laterally, the material can enter the feeding channel 28 through the notch 282. Then, the material is pushed to the clamping unit of the turntable fixture 6 by the second pusher 27. Of course, the feeding channel 28 is located on the movement path of the second pusher 27, and the front end of the second pusher 27 can be adapted to the shape of the material.

[0045] After the material is clamped in the clamping unit of the turntable fixture 6, it is moved to the double-sided cutting unit of station two by rotation to carry out the next process.
