DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] In this embodiment, if Figure 1-Figure 6As shown, the circular knife machine device with adjustable spacing includes a base 101, and support plates 102 are arranged on the top of both ends of the base 101. The base 101 and the support plates 102 play the role of supporting the conveying roller 107 and the knife roller 104. A slide groove 103 is opened on the surface of the support plate 102. The function of the slide groove 103 is to facilitate the sliding of the slide plate 205 to ensure the normal operation of the adjustment mechanism 200. A knife roller 104 is installed between the support plates 102. The surface of the knife roller 104 is provided with a scale bar, which is convenient for accurately adjusting the distance between different circular knives 105, so that the distances between multiple circular knives 105 can be consistent, or different, to meet different cutting requirements. The two ends of the rotating shaft of the knife roller 104 are inside the slide groove 103, and the outer side of the knife roller 104 is provided with a scale bar. A plurality of circular knives 105 are installed on the side, and the circular knives 105 are slidably connected with the knife roller 104, so as to facilitate the replacement of knives with different cutting lengths. The circular knives 105 also include an adjusting mechanism 200 and a moving mechanism 300. The adjusting mechanism 200 is arranged on both sides of the knife roller 104, and is used to change the distance of the knife roller 104. The moving mechanism 300 is arranged on one side of the circular knife 105, and is used to adjust the position of each circular knife 105 on the knife roller 104. Before the circular knife machine device with adjustable spacing starts to be used, the adjusting mechanism 200 and the moving mechanism 300 are adjusted according to the specifications of the material to be cut, and the distance between the knife roller 104 and the conveying roller 107 is adjusted, and then the position of the circular knife 105 is adjusted according to the cutting length of the material, so that the device enters a waiting state;

[0027] Among them Figure 2-Figure 5 As shown, the adjustment mechanism 200 includes two first bevel gears 201, which are both arranged on the side of the support plate 102 away from the knife roller 104. The two first bevel gears 201 have the same direction and are fixedly connected by a connecting rod 202. The connecting rod 202 is rotatably connected to the support plate 102. The connecting rod 202 makes the first bevel gears 201 on both sides of the support plate 102 rotate synchronously, which is convenient for quickly and synchronously adjusting the height of the rotating shaft of the knife roller 104. The lower end of the first bevel gear 201 is meshedly connected with the second bevel gear 201. 03. A screw rod 204 is fixedly mounted on the lower surface of the second bevel gear 203. The threads on the two screw rods 204 are in the same direction, so that when the handle 206 is turned, the screw rods 204 on both sides rotate in the same direction to achieve the effect of synchronous lifting. A sliding member is arranged on the outer side of the screw rod 204. The adjustment mechanism 200 drives the slide plate 205 to move so as to adjust the distance between the knife roller 104 and the conveying roller 107, so that the circular knife 105 on the knife roller 104 can just cut materials of different thicknesses, adapt to cutting materials of different thicknesses, and improve the cutting accuracy of materials;

[0028] Among them Figure 3 and Figure 6As shown, the moving mechanism 300 includes a groove 301 formed on the surface of the knife roller 104, and a plurality of sliders are slidably arranged inside the groove 301. An annular block 302 is fixedly installed on the outer side of the slider. The annular block 302 is engaged with the circular knife 105. The annular block 302 is first moved to the corresponding position, and then a suitable circular knife 105 is selected and fixed on the outer side of the annular block 302 to meet different cutting requirements. Bolts 303 are arranged on the surface of the annular block 302, and the position of the annular block 302 is fixed by bolts, which is convenient for quick operation.

[0029] Among them Figure 4 and Figure 5 As shown, the sliding member includes a slide plate 205 threadedly connected to the screw rod 204, the slide plate 205 is slidably connected to the slide groove 103, and the slide plate 205 is rotatably connected to the knife roller 104. A first motor is installed inside one of the slide plates 205, and the output end of the first motor is fixedly connected to the rotating shaft of the knife roller 104. When the height of the knife roller 104 needs to be adjusted, the turning handle 206 is turned to drive the first bevel gear 201 and the second bevel gear 203 to engage in transmission, so that the screw rod 204 rotates to move the slide plate 205 up and down, so as to realize the lifting and lowering of the knife stick 104. The operation is simple, and because the screw rod 204 is threadedly connected to the slide plate 205, the knife roller 104 will not move by itself after the adjustment is completed, and it has self-locking property;

[0030] Among them Figure 2 As shown, one end of the connecting rod 202 passes through one of the first bevel gears 201 and is connected to a turning handle 206, which is convenient for the use of the adjustment mechanism 200. The turning handle 206 can drive the connecting rod 202 to rotate, thereby driving the first bevel gear 201 and the second bevel gear 203 to rotate, thereby adjusting the distance between the knife stick 104 and the conveying roller 107;

[0031] Among them Figure 2 As shown, a fixing block 207 is provided at the lower end of the screw 204, and the screw 204 is rotatably connected to the fixing block 207 through a bearing, and the fixing block 207 is fixedly connected to the support plate 102, so as to limit the position of the screw 204, prevent the screw 204 from moving up and down, avoid deviation, and avoid affecting the meshing transmission between the gears;

[0032] Example 2

[0033] The difference from Example 1 is that Figure 1 As shown, a support base 106 is symmetrically arranged at the lower end of the base 101, and the support base 106 plays a supporting role, which facilitates movement and thus increases the overall practicality of the device.

[0034] Among them Figure 1As shown, a conveying roller 107 is rotatably connected between the support plates 102, one end of the conveying roller 107 extends to the outside of the support plate 102 and is fixedly connected to the output end of the second motor. The second motor drives the conveying roller 107 to transport the material to be cut, so that the circular knife 105 on the knife roller 104 can cut the material.

[0035] Before the use of the circular knife machine device with adjustable spacing, the device is pushed to the site where material cutting is required. When the position between the knife stick 104 and the conveying roller 107 needs to be adjusted, the first bevel gear 201 and the connecting rod 202 are rotated by turning the handle 206, and the first bevel gear 201 drives the second bevel gear 203 to mesh and transmit, so that the screw rod 204 and the second bevel gear 203 rotate in the same direction. Due to the restriction of the fixed block 207, the screw rod 204 only rotates, driving the slide plate 205 to move up and down, thereby moving the knife stick 104 up and down, and moving several annular blocks 302 to corresponding positions according to the specifications of the cut material, and then selecting a circular knife 105 of appropriate size, and fixing the circular knife 105 on the outside of the annular block 302 to adapt to different cutting requirements, so that the tool specifications of the circular knife 105 are adapted to the material thickness, and tightening the bolt 303 to fix the position of the annular block 302 for easy operation.

[0036] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
