[0028] Correction: Correction is performed on the rubber conveyor belt material to be cut by at least two groups of correction wheels that can move along the axial direction of the feed roller.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention can push the rubber conveyor belt raw material to move along the axial direction of the feed roller by setting the movement of two sets of moving wheels, thereby adjusting the position of the rubber conveyor belt raw material in the feed channel, and then correcting the rubber conveyor belt raw material to improve the cutting accuracy.

[0031] 2. The present invention sets a first support rod for carrying the first spring and the first correction wheel, so that the first correction wheel is on the same straight line, so that the force is more balanced when pushing the rubber conveyor belt material. Since the width of the rubber conveyor belt material is different, the position of the first correction wheel can be adjusted by moving the first slider, so as to match the rubber conveyor belt material of different widths. In addition, by adjusting the position of the first slider, the squeezing force of the first correction wheel on the rubber conveyor belt material can also be adjusted;

[0032] 3. In the present invention, the first correction wheel is connected to a first spring on one side, and the second correction wheel is provided with a pusher on one side, and the pusher can push the second correction wheel to move along the axial direction of the feed roller, so that only one pusher is provided to adjust the positions of the first correction wheel and the second correction wheel at the same time;

[0033] 4. The present invention can adjust the position of the first correction wheel by moving the first slider, so as to match with rubber conveyor belt materials of different widths. In addition, by adjusting the position of the first slider, the squeezing force of the first correction wheel on the rubber conveyor belt material can also be adjusted, so that the position of the first correction wheel can be adjusted in a wide range;

[0034] 5. The present invention sets a first connecting rod to link the first correction wheel with the second correction wheel. When the second correction wheel is pushed to move, the second connecting rod pushes the first connecting rod to move, thereby driving the first correction wheel to move, so that the first correction wheel and the second correction wheel move in the same direction at the same time. While correcting the position of the rubber conveyor belt raw material, the deformation of the rubber conveyor belt raw material can be reduced, thereby improving the cutting accuracy.

[0035] 6. The present invention can automatically adjust and drive the first correction wheel to move a small distance in the same direction according to the deformation amount of the rubber conveyor belt raw material when it is subjected to force, so that the second correction wheel moves a large distance; the deformation amount of the soft rubber conveyor belt raw material after being squeezed is larger, at this time, the first correction wheel moves a little more, thereby reducing the deformation amount of the soft rubber conveyor belt raw material and improving the cutting accuracy. Similarly, the deformation amount of the hard rubber conveyor belt raw material after being squeezed is smaller, at this time, the first correction wheel moves a little less, thereby reducing the deformation amount of the soft rubber conveyor belt raw material and improving the cutting accuracy. In the above process, the compression and correction of the rubber conveyor belt raw material can be achieved at the same time, and the structure can also realize the function of fixedly connecting the first correction wheel and the second correction wheel;

[0036] 7. In the present invention, when the first correction wheel and the second correction wheel are not linked, the first correction wheel is locked. Of course, in some embodiments, it can still be moved by a spring. When the first connecting rod links the first correction wheel and the second correction wheel, a mechanism is provided to automatically unlock the first correction wheel, and there is no need to manually switch between the two states, thereby facilitating switching.

[0055] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0056] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0057] Example 1

[0058] See also Figure 1 A rubber conveyor belt production corner cutting device with correction function comprises a feeding mechanism 100, a cutting mechanism 200 and a correction mechanism 300.

[0059] The feeding mechanism 100 includes two sets of feeding rollers 110 , the axes of the feeding rollers 110 are parallel, and a feeding channel 120 is provided between the feeding rollers 110 ;

[0060] The cutting mechanism 200 includes a cutting wheel 210, the edge of which has a cutting blade 211, the rotation axis of the cutting wheel 210 is parallel to the axis of the feed roller 110, the cutting wheel 210 is located on one side of the feed roller 110, and the cutting wheel 210 is at least partially located in the extension area of ​​the feed channel 120;

[0061] The correction mechanism 300 includes at least two groups of correction wheels 310 that can move along the axial direction of the feed roller 110 , and the two groups of correction wheels 310 are respectively located at two ends of the feed roller 110 ; at least part of the working area of ​​the correction wheel 310 is located in the extension area of ​​the feed channel 120 .

[0062] In this embodiment, the rubber conveyor belt material to be cut is placed in the feeding channel 120, and the two surfaces of the rubber conveyor belt material to be cut are respectively in contact with the surfaces of the two feeding rollers 110, so that when the two sets of feeding rollers 110 rotate relative to each other, the rubber conveyor belt material to be cut can be moved for feeding.

[0063] It should be noted that, in the figure, in order to prevent slipping during feeding, each set of feed rollers 110 is provided with two, which can feed efficiently. However, as required, each set of feed rollers 110 can also be provided with more or less. In the figure, the two sets of feed rollers 110 are arranged up and down, but according to actual needs, they can also be arranged left and right or inclined, all within the protection scope of this embodiment. In addition, the position ensures the feeding efficiency, and an anti-slip layer can be provided on the surface of the feed roller 110.

[0064] The cutting mechanism 200 is used to cut the rubber conveyor belt material to be cut. According to the actual use requirements, the excess on one side of the rubber conveyor belt material can be cut off, or the wide rubber conveyor belt material can be cut into two narrow rubber conveyor belts. The extension area of ​​the feed channel 120 is the area where the rubber conveyor belt material to be cut can be extended. At least part of the correction wheel 310 is located in the extension area of ​​the feed channel 120, so the rubber conveyor belt material can be cut.

[0065] The correction mechanism 300 is used to correct the position of the rubber conveyor belt raw material, thereby improving the cutting accuracy and ensuring the quality of the product. Exemplarily, if the moving direction of the rubber conveyor belt raw material is set to the front, the two sets of correction wheels 310 are respectively located on the left and right sides of the rubber conveyor belt raw material. Through the movement of the two sets of correction wheels 310, the rubber conveyor belt raw material can be pushed to move along the axial direction of the feed roller 110, thereby adjusting the position of the rubber conveyor belt raw material in the feed channel 120, and then correcting the rubber conveyor belt raw material to improve the cutting accuracy. In this embodiment, the working area of ​​the correction wheel 310 is the outer cylindrical surface of the correction wheel, and at least part of the working area of ​​the correction wheel 310 is located in the extension area of ​​the feed channel 120, so that the working area of ​​the correction wheel 310 and the edge of the rubber conveyor belt raw material can be fitted, thereby pushing the rubber conveyor belt raw material to move.

[0066] Furthermore, the outer circumferential surface of the correction wheel 310 has an annular receiving groove 320, and the edge of the annular receiving groove 320 has a round chamfer. At this time, the working area of ​​the correction wheel 310 is the bottom surface of the annular receiving groove 320, which is also a circumferential surface. Through this setting, the correction wheel 310 has the following functions: first, it pushes the rubber conveyor belt raw material to move, thereby correcting the position of the rubber conveyor belt raw material and improving the cutting accuracy; second, when the correction wheel 310 does not move, it can guide the rubber conveyor belt raw material; third, the two sides of the rubber conveyor belt raw material are located in the annular receiving groove, thereby preventing the correction wheel and the rubber conveyor belt raw material from being separated, and reducing the degree of downward bending of the rubber conveyor belt raw material due to gravity.

[0067] Example 2

[0068] Please refer to 2 , the correction wheel 310 located at one end of the feeding roller 110 is a first correction wheel 311 ; the correction wheel 310 located at the other end of the feeding roller 110 is a second correction wheel 312 ;

[0069] There are at least two first correction wheels 311, and the connecting line of the first correction wheels 311 is perpendicular to the feeding roller 110, and one side of each first correction wheel 311 is connected to a first spring 3111;

[0070] There is at least one second correction wheel 312 . A pusher 330 is disposed on a side of the second correction wheel 312 away from the first correction wheel 311 . The pusher 330 can push the second correction wheel 312 to move along the axial direction of the feeding roller 110 .

[0071] In this embodiment, through the above arrangement, the pusher 330 pushes the second correction wheel 312 to move, thereby pushing the rubber conveyor belt raw material to move to one side of the first correction wheel 311. Since the first correction wheel 311 is connected to the first spring 3111, the first spring 3111 can be compressed to move, and the movement of the rubber conveyor belt raw material will not be hindered. In addition, when the pusher 330 moves in the reverse direction, the elastic force of the first spring 3111 can push the first correction wheel 311 to move in the reverse direction, thereby pushing the rubber conveyor belt raw material to move to one side of the second correction wheel 312. In this way, the left and right positions of the rubber conveyor belt raw material can be corrected.

[0072] Furthermore, it should be noted that, in the present embodiment, there are at least two first correction wheels 311 and at least one second correction wheel 312, so that the two sides of the rubber conveyor belt raw material can be limited. When the rubber conveyor belt raw material is pushed to move left and right, the rubber conveyor belt raw material will not tilt. Therefore, it has the function of secondary correction of the rubber conveyor belt raw material.

[0073] In this embodiment, the pushing member 330 may be an electric push rod or a cylinder.

[0074] Example 3

[0075] See 2 and Figure 3 The end of the first spring 3111 away from the first correction wheel 311 is fixedly connected to the same first support rod 340. One side of the first support rod 340 has a first slider 351. The first slider 351 can move along the first slide 352 and can be locked on the first slide 352.

[0076] In this embodiment, through the above arrangement, the first support rod 340 is used to carry the first spring 3111 and the first correction wheel 311, so that the first correction wheel 311 is on the same straight line, so that the force is more balanced when pushing the rubber conveyor belt raw material.

[0077] Since the width of the rubber conveyor belt material is different, the position of the first correction wheel 311 can be adjusted by moving the first slider 351, so as to match the rubber conveyor belt material of different widths. In addition, by adjusting the position of the first slider 351, the squeezing force of the first correction wheel 311 on the rubber conveyor belt material can also be adjusted.

[0078] Example 4

[0079] The problem with the above embodiment is that when the rubber conveyor belt material pushes the first correction wheel 311 to move, it will also be subjected to a reverse thrust, thereby causing the rubber conveyor belt material to deform and reduce the cutting accuracy.

[0080] See also Figure 4 , 5 6. A first extension rod 341 is fixedly connected to the first support rod 340, and a first connecting rod 342 is connected to one side of the first extension rod 341;

[0081] There are several second correction wheels 312, and the several second correction wheels 312 are all connected to the same second support rod 360. The second support rod 360 is fixedly connected to a second extension rod 361, and one side of the second extension rod 361 is fixedly connected to a second connecting rod 362. The first connecting rod 342 and the second connecting rod 362 are connected by a connecting structure 370.

[0082] Through the connecting structure 370, while pushing the second correction wheel 312 to move, the second connecting rod 362 pushes the first connecting rod 342 to move, thereby driving the first correction wheel 311 to move, so that the first correction wheel 311 and the second correction wheel 312 move in the same direction at the same time, and while correcting the position of the rubber conveyor belt raw material, the deformation of the rubber conveyor belt raw material can be reduced, thereby improving the cutting accuracy.

[0083] It should be noted that, during the above working process, the first slider 351 and the first slideway 352 are in an unlocked state, so the first correction wheel 311 can move. In addition, the second correction wheel 312 can also be connected to the same second support rod 360 through a spring, thereby playing a buffering role.

[0084] It should also be noted that, although the first correction wheel 311 and the second correction wheel 312 can move simultaneously in the same direction, they do not necessarily move the same distance. The following describes two situations: the first correction wheel 311 and the second correction wheel 312 move the same distance and the second correction wheel 312 move different distances.

[0085] Case 1: The first correction wheel 311 and the second correction wheel 312 move at the same distance, and the first correction wheel 311 and the second correction wheel 312 can be fixedly connected by a connecting structure such as bolts, so that the first correction wheel 311 and the second correction wheel 312 move synchronously and at the same distance. In this way, when correcting the position of the rubber conveyor belt raw material, the extrusion of the rubber conveyor belt raw material will not be increased, so its deformation will not increase, thereby increasing the cutting accuracy, and the rubber conveyor belt raw material can also be translated a larger distance as a whole.

[0086] Case 2: Considering that the case 1 is not flexible to use, which is specifically manifested in the weak compaction effect on the rubber conveyor belt raw material, the first correction wheel 311 and the second correction wheel 312 are set to be able to move at different distances, so that they can have a compaction effect while performing correction, as follows:

[0087] Example 5

[0088] See also Figure 7 The connection structure 370 includes a stepper motor 371, the stepper motor 371 is fixedly connected to the first connection rod 342, and the output end of the stepper motor 371 is fixedly connected to a pressing plate 372;

[0089] The connection structure 370 further includes a bearing plate 373, which is fixedly connected to one end of the second connection rod 362 close to the first connection rod 342, the bearing plate 373 corresponds to the pressure plate 372, and a plurality of second springs 374 are fixedly connected to the bearing plate 373;

[0090] Driven by the same displacement of the first connecting rod 342, the stepper motor 371 adjusts the position of the pressure plate 372, and the pressure plate 372 presses different second springs 374, thereby pushing the second connecting rod 362 to move different distances; the stepper motor 371 signal is connected to the length measuring sensor 380, and the length measuring sensor 380 is used to detect the size change of the rubber between the first correction wheel 311 and the second correction wheel 312.

[0091] In this embodiment, initially, the first slider 351 is locked in the first slideway 352, and the first correction wheel 311 and the second correction wheel 312 operate as in Embodiment 1. When the length measuring sensor 380 detects that the rubber conveyor belt material is squeezed and deformed by the first correction wheel 311 and the second correction wheel 312 to reach different predetermined values, the length measuring sensor 380 sends a signal to the stepping motor 371 through the controller, so that the pressing plate 372 pushes the second spring 374, and the lock on the first slider 351 is released, which can drive the second connecting rod 362 to move, so that the second correction wheel 312 also produces a certain displacement. Since the second spring 374 is compressed during this process, the first connecting rod 342 and the second connecting rod 362 do not move the same distance.

[0092] The advantage of this embodiment is that the deformation of the soft rubber conveyor belt material after being squeezed is larger. At this time, the pressure plate 372 and the more "hard" second spring 374 are matched to make the displacement of the first correction wheel 311 larger, thereby reducing the deformation of the soft rubber conveyor belt material and improving the cutting accuracy. Similarly, the deformation of the hard rubber conveyor belt material after being squeezed is smaller. At this time, the pressure plate 372 and the more "soft" second spring 374 are matched to make the displacement of the first correction wheel 311 smaller, thereby reducing the deformation of the soft rubber conveyor belt material and improving the cutting accuracy. In the above process, the compression and correction of the rubber conveyor belt material can be achieved at the same time.

[0093] It should be noted that, when the first slider 351 is always sliding, the first correction wheel 311 cannot squeeze the rubber conveyor belt raw material, and this embodiment cannot be used. Therefore, the first slider 351 and the first slideway 352 are also connected by a third spring 353, so that the first slider 351 is always pushed by the third spring 353, so that the first correction wheel 311 can squeeze the rubber conveyor belt raw material.

[0094] Exemplarily, in order to achieve the cooperation between the pressure plate 372 and different second springs 374, so as to move the first correction wheel 311 by different distances, the following settings are performed:

[0095] The pressing plate 372 is fixedly connected to one side of the output end of the stepping motor 371;

[0096] Multiple second springs 374 are distributed in a circular array on the pressure plate 372 relative to the axis of the output end of the stepper motor 371. The multiple second springs 374 have equal lengths and different stiffness coefficients. The pressure plate 372 can contact at least one second spring 374.

[0097] Furthermore, the second spring 374 is easily deflected when squeezed, so a spring guide mechanism 400 is provided, including a guide rod 410, which is fixedly connected to the bearing plate 373, and a guide sleeve 420 is slidably sleeved on the guide rod 410, and the guide sleeve 420 is connected to the second spring 374.

[0098] Therefore, when the second spring 374 is compressed, the guide sleeve 420 moves along the guide rod 410, thereby driving the second spring 374 to be compressed along its own axis.

[0099] See also Figure 8 Furthermore, in order to enable the present connection structure to simultaneously realize the movement of the first connecting rod 342 and the second connecting rod 362 at the same distance, a tightening screw 430 is connected to the guide sleeve 420 through threaded rotation, and the end of the tightening screw 430 can press the guide rod 410, and the guide sleeve 420 can be detachably connected to the pressure plate 372, so that the second spring 374 cannot be compressed.
