[0026] The described driving mechanism 7 includes a motor 71, a rotating shaft 72, and a transition shaft 73. The motor 71 is installed above the upper frame of the gantry frame 101 near the end position. The lower end of the motor 71 drives and connects the upper sliding mechanism 5 through the rotating shaft 72 passing through the upper frame of the gantry frame 101. The lower end of the rotating shaft 72 is connected to the transition shaft 73. The transition shaft 73 passes through the upper frame of the gantry frame 101 and then penetrates into the lower frame of the gantry frame 101 to drive and connect the lower sliding mechanism 6. One motor 71 realizes synchronous driving of the upper and lower sliding mechanisms through the transition shaft 73.

[0027] The described upper sliding mechanism 5 includes a slider 51, a slide rail 52, belt pulleys 53, and a belt 54. The slide rail 52 is installed on the upper frame of the gantry frame 101. The slider 51 is slidably installed on the slide rail 52. There are two belt pulleys 53 which are respectively installed near both ends of the upper frame of the gantry frame 101. The belt 54 is wound around the outside of the two belt pulleys 53. The inner side of the slider 51 is fixedly connected to the upper surface of the belt 54. The lower end of the rotating shaft 72 drives and connects one of the belt pulleys 53. One end of the upper tool rest 1 is rotatably connected to the outside of the slider 51; The described lower sliding mechanism 6 includes a slider 61, a slide rail 62, belt pulleys 63, and a belt 64. The slide rail 62 is installed on the lower frame of the gantry frame 101. The slider 61 is slidably installed on the slide rail 62. There are two belt pulleys 63 which are respectively installed near both ends of the lower frame of the gantry frame 101. The belt 64 is wound around the outside of the two belt pulleys 63. The inner side of the slider 61 is fixedly connected to the upper surface of the belt 64. The lower end of the transition shaft 73 drives and connects one of the belt pulleys 63. One end of the lower tool rest 3 is rotatably connected to the outside of the slider 61.

[0028] The other end of the upper tool rest 1 and the other end of the lower tool rest 3 are connected by a support column 10. One side of the support column 10 is designed with a knife groove that penetrates up and down. The ring knife 8 passes through the knife groove.

[0029] The upper tool rest 1 includes a front housing 11 and a rear housing 12. The front housing 11 and the rear housing 12 are symmetrically designed and fixed together. The front housing 11 and the rear housing 12 respectively arch outwards and form a cavity between them. Guide wheels 13 are respectively installed at both ends inside the cavity; The lower tool rest 3 also includes a front housing and a rear housing. The front housing and the rear housing are symmetrically designed and fixed together. The front housing and the rear housing respectively arch outwards and form a cavity between them. Guide wheels 13 are also respectively installed at both ends inside the cavity; The ring knife 8 is wound around the outside of the four guide wheels 13. The structural design of the upper tool rest 1 and the lower tool rest 3 ensures the fixed installation of the ring knife guide wheels while protecting the ring knife tool itself and the safety of personnel, avoiding being injured by touching the ring knife. At the same time, the cavity is designed to reduce the weight of the equipment.

[0030] An upper twisting knife mechanism 9 is installed at the lower end of the outer side of the slider 51 of the upper sliding mechanism 5, and a lower twisting knife mechanism 90 is also installed at the upper end of the outer side of the slider 51 of the lower sliding mechanism 6; the ring knife passes through the upper twisting knife mechanism and the lower twisting knife mechanism. The twisting knife mechanism is a prior art and controls the cutting direction of the ring knife.

[0031] A driving motor 20 is installed on the side of the lower tool rest 3 away from the slider 61, and the driving motor 20 is fixed on the front housing or the rear housing, and the driving motor 20 is drivingly connected to the guide wheel 13 on the side away from the slider 61 in the cavity of the lower tool rest 3.

[0032] The lower part of the end of the upper tool rest 1 close to the gantry frame 101 is designed with an outwardly inclined chamfer, and the outer ring of the guide wheel installed at this end extends out of the chamfer position of the upper tool rest 1, and the upper part of this end is rotatably connected to the slider 51 of the upper sliding mechanism 5; the upper part of the end of the lower tool rest 3 close to the gantry frame 101 is designed with an outwardly inclined chamfer, and the outer ring of the guide wheel installed at this end extends out of the chamfer position of the lower tool rest 3, and the lower part of this end is rotatably connected to the slider 51 of the lower sliding mechanism 6. The inclined chamfer design of the upper tool rest 1 and the lower tool rest 3 ensures that the ring knife can rotate, and avoids affecting the operation of the ring knife during the rotation of the upper tool rest 1 and the lower tool rest 3 and avoiding interference with the slider 51.

[0033] The other end of the upper support 2 is rotatably connected to the left end or the right end of the upper frame of the gantry frame 101; the other end of the lower support 4 is rotatably connected to the left end or the right end of the lower frame of the gantry frame 101.

[0034] When the present invention is in use, the conveying workbench 102 passes through the middle of the gantry frame 101. The conveying workbench 102 is divided into a front conveying workbench 102 and a rear conveying workbench 102. There is a gap between the front conveying workbench 102 and the rear conveying workbench 102, and this gap is used for the ring knife to move during cutting; the driving mechanism 7 drives the slider 61 of the upper and lower sliding mechanisms 6 to slide left and right, so as to drive the upper tool holder 1 to perform folding or stretching actions under the rotational support of the upper support 2. At the same time, the lower tool holder 3 also performs corresponding synchronous actions. In this way, the circular tool moves left and right during the cutting process, and the circular tool holder performs folding or stretching actions, occupying the original front and rear space, unlike in the past which occupied the left and right space. In this way, the left and right space can be saved, and the overall use space of the equipment becomes smaller, and the overall structure of the equipment is more compact; one end of the upper tool holder 1 is rotatably connected to the slider 51, and the other end is rotatably connected to one end of the upper support 2 near the end position. The other end of the upper support 2 is rotatably fixed at one end of the gantry frame 101. When the slider 51 moves, the upper tool holder 1 and the upper support 2 will also move. Since the other end of the upper support 2 is rotatably fixed on the gantry frame 101 and the slider 51 slides on the gantry frame 101, the middle-connected upper tool holder 1 and upper support 2 have no possibility of moving left and right, so they can only perform folding or stretching actions. The lower tool holder 3 and the lower support 4 are designed in the same way. In this way, it is ensured that the ring knife support changes from left and right horizontal movement to front and rear folding or stretching actions. The upper and lower two sliders 51 and 61 are designed with a tool-twisting mechanism to ensure the normal working cutting direction of the working side of the ring knife and normal left and right movement. Due to the structural limitation of the conveying workbench 102, the longest distance formed after the lower tool holder 3 and the lower support 4 are connected, that is, the length after being stretched out, is greater than or equal to the length of the slide rail. The length of the lower tool holder 3 is greater than the width of the conveying workbench 102 to avoid interference of the non-working side of the ring knife with the conveying workbench 102. In the present invention, a column 10 is designed. The inside of the column is hollow-designed to form a tool groove. The ring knife 8 passes through the tool groove, so the column 10 cannot interfere with the conveying workbench 102; the design of the column serves one purpose of supporting and connecting the upper and lower tool holders 3, and another purpose is that the ring knife passes through the inside of the column, will not be touched by the outside world, will not damage the ring knife itself, nor will it accidentally injure the operator or damage the product, which is safe and reliable.
