Description

Technical Field

[0001] The present invention relates to the technical field of wire cutting machines, and particularly to a tension roller set for a wire cutting machine. Background Art

[0002] Currently, when using mesh materials, a wire cutting machine is required to cut the mesh materials. On a wire cutting machine device, in order to ensure the stability of the mesh material during the conveying process, a tension roller set is generally provided to tension the mesh material during the transmission process.

[0003] However, in the existing technology, the tension roller set on the wire cutting machine cannot finely adjust the tension roller according to actual needs. When the mesh material passes between the transmission roller and the tension roller, it is difficult to maintain a relatively natural state, and it is easy to deform, resulting in poor stability and reliability of the mesh material during the conveying process, and it is difficult to ensure the normal conveying of the mesh material. For this reason, the present invention proposes a tension roller set for a wire cutting machine. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a tension roller set for a wire cutting machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A tension roller set for a wire cutting machine includes two parallel tension frames, and the bottoms of the two tension frames are fixedly connected by a tension base. A transmission roller and a tension roller located below the transmission roller are rotatably arranged between the two tension frames. A fixed rod and a movable rod are respectively rotatably sleeved inside the transmission roller and the tension roller, and both ends of the fixed rod are respectively fixedly connected to one side of the two tension frames close to each other. Strip-shaped holes are provided on both tension frames, and both ends of the movable rod respectively slide through the two strip-shaped holes;

[0007] Both bottom ends of the movable rod located in the two strip-shaped holes are fixedly connected with vertical rods. An adjustment cavity is provided on the tension base. An activity plate is slidably installed in the adjustment cavity along the vertical direction. The bottoms of both vertical rods slide through to the inside of the adjustment cavity and are fixedly connected to the top of the activity plate. An installation hole is provided at the central position of the activity plate. A threaded sleeve is fixedly sleeved inside the installation hole. An adjustment screw is connected to the threaded sleeve through a thread. The top end of the adjustment screw rotates and extends above the tension base and is fixedly sleeved with an adjustment knob. The bottom end of the adjustment screw is rotatably installed on the bottom inner wall of the adjustment cavity.

[0008] Preferably, symmetrically arranged vertical sliding rods are fixedly provided in the adjustment cavity. Vertical sliding holes are provided on the activity plate, and the activity plate is slidably sleeved on the vertical sliding rods through the vertical sliding holes.

[0009] Preferably, an internal thread is provided on the inner wall of the threaded sleeve, an external thread is provided on the outer wall of the adjusting screw rod, and the external thread on the adjusting screw rod matches the internal thread on the threaded sleeve.

[0010] Preferably, a rotating seat is fixedly arranged on the bottom inner wall of the adjusting cavity, and the bottom end of the adjusting screw rod is rotatably installed on the rotating seat.

[0011] Preferably, a rotating hole is provided at the center of the top inner wall of the adjusting cavity, and the adjusting screw rod rotatably penetrates through the rotating hole.

[0012] Preferably, through holes are provided on both the bottom inner wall of the strip-shaped hole and the top inner wall of the adjusting cavity, and the vertical rod slidably penetrates through the two through holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the present invention, by driving the adjusting screw rod to rotate through the adjusting knob, the movable plate can perform up-and-down threaded transmission on the adjusting screw rod through the threaded sleeve. When the movable plate moves, it drives the movable rod to move up and down in the strip-shaped hole through the vertical rod, and the movable rod drives the tensioning roller to move up and down, thereby adjusting the distance between the tensioning roller and the driving roller and realizing fine adjustment of the tensioning roller.

[0015] In summary, the tensioning roller group of the cutting machine in the present invention can finely adjust the tensioning roller according to actual needs, so as to ensure that the net-shaped material maintains its relatively natural state when passing between the driving roller and the tensioning roller, thereby ensuring the stability and reliability of the net-shaped material during the conveying process, avoiding the disadvantage that the tensioning roller group of the conventional cutting machine cannot be finely adjusted according to actual needs, and being beneficial to ensuring the normal conveying of the net-shaped material.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-3 , a tension roller group of a net cutting machine includes two tension frames 2 arranged in parallel, and the bottoms of the two tension frames 2 are fixedly connected through a tension base 1. A driving roller 3 and a tension roller 4 located below the driving roller 3 are rotatably arranged between the two tension frames 2. A fixed rod 301 and a movable rod 401 are respectively rotatably sleeved inside the driving roller 3 and the tension roller 4. The two ends of the fixed rod 301 are respectively fixedly connected to one side of the two tension frames 2 close to each other. Strip-shaped holes 14 are provided on both tension frames 2, and the two ends of the movable rod 401 respectively slide through the two strip-shaped holes 14;

[0022] Both bottom ends of the movable rod 401 located in the two strip-shaped holes 14 are fixedly connected with vertical rods 13. An adjustment cavity 11 is provided on the tension base 1. An activity plate 8 is slidably installed in the adjustment cavity 11 along the vertical direction. The bottoms of the two vertical rods 13 both slide through to the inside of the adjustment cavity 11 and are fixedly connected to the top of the activity plate 8. An installation hole is provided at the central position of the activity plate 8. A threaded sleeve 7 is fixedly sleeved inside the installation hole. An adjustment screw rod 6 is connected to the threaded sleeve 7 through threads. The top end of the adjustment screw rod 6 rotates and extends above the tension base 1 and is fixedly sleeved with an adjustment knob 5. The bottom end of the adjustment screw rod 6 is rotatably installed on the bottom inner wall of the adjustment cavity 11. The tension roller group of the net cutting machine in the present invention can finely adjust the tension roller 4 according to actual needs, so as to ensure that the net-shaped material maintains its natural state when passing between the driving roller 3 and the tension roller 4, thereby ensuring the stability and reliability of the net-shaped material during the conveying process, avoiding the drawback that the conventional tension roller group of the net cutting machine cannot be finely adjusted according to actual needs, and being beneficial to ensuring the normal conveying of the net-shaped material.

[0023] Specifically, symmetrically arranged vertical sliding rods 10 are fixedly provided in the adjustment cavity 11. Vertical sliding holes 9 are provided on the activity plate 8, and the activity plate 8 is slidably sleeved on the vertical sliding rods 10 through the vertical sliding holes 9.

[0024] Specifically, internal threads are provided on the inner wall of the threaded sleeve 7, external threads are provided on the outer wall of the adjustment screw rod 6, and the external threads on the adjustment screw rod 6 match the internal threads on the threaded sleeve 7.

[0025] Specifically, a rotating seat 12 is fixedly arranged on the bottom inner wall of the adjustment cavity 11, and the bottom end of the adjustment screw rod 6 is rotatably installed on the rotating seat 12.

[0026] Specifically, a rotating hole is provided at the center of the top inner wall of the adjustment cavity 11, and the adjustment screw rod 6 rotates through the rotating hole.

[0027] Specifically, through holes 15 are provided on the inner wall of the bottom of the strip-shaped hole 14 and on the inner wall of the top of the adjustment cavity 11, and the vertical rod 13 slidably penetrates through the two through holes 15.

[0028] The tensioning roller set of the cutting machine in the present invention can finely adjust the tensioning roller 4 according to actual needs. When adjustment is required, by rotating the adjustment knob 5, the adjustment screw 6 is driven to rotate on the rotating seat 12. When the adjustment screw 6 rotates, it rotates relative to the threaded sleeve 7 on the movable plate 8. Since the movable plate 8 is slidably guided and limited on the vertical slide bar 10 through the vertical slide hole 9, when the adjustment screw 6 rotates, the movable plate 8 can perform up and down threaded transmission on the adjustment screw 6 through the threaded sleeve 7. When the movable plate 8 moves, it drives the movable rod 401 to move up and down in the strip-shaped hole 14 through the vertical rod 13, and the movable rod 401 drives the tensioning roller 4 to move up and down, thereby adjusting the distance between the tensioning roller 4 and the transmission roller 3 to achieve fine adjustment of the tensioning roller 4. In this way, it can ensure that the mesh material remains in its natural state when passing between the transmission roller 3 and the tensioning roller 4, thus ensuring the stability and reliability of the mesh material during transportation, avoiding the drawback that the tensioning roller set of the conventional cutting machine cannot finely adjust the tensioning roller according to actual needs, and ultimately facilitating the normal transportation of the mesh material.
