Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an automatic rubber cutting and weighing device, comprising a workbench 1, which supports the device, and a front surface of the workbench 1 is detachably connected to an observation screen 2, through which a worker can directly obtain the cutting information of the rubber rod, providing convenience for the worker to adjust the device, an electric push rod 3 is fixedly connected to the axis of the upper surface of the workbench 1, and a cutting knife 31 is detachably connected to the lower surface of the electric push rod 3, and the cutting knife 31 is cooperated with the electric push rod 3 to make the cutting knife 31 move downward, and a cutting groove 11 is opened at the axis of the bottom of the inner wall of the workbench 1 to cut the rubber rod in the material transport groove 12, and a material transport groove 12 is opened on the left and right sides of the bottom of the inner wall of the workbench 1 near the cutting groove 11, and four sets of guide rollers 13 are rotatably connected to the left and right ends of the bottom surface of the inner wall of the workbench 1, and the guide rollers 13 are started to rotate to transport the rubber rod, thereby improving the convenience of transporting the rubber rod in the device.
[0033] Reference Figure 2 - Figure 4During the cutting process of the cutting knife 31, the auxiliary component 4 is started. The auxiliary component 4 is arranged on the top of the workbench 1. The auxiliary component 4 includes a mounting frame 41 and a sharpening plate 48. The mounting frame 41 is fixedly connected to the right side of the axis of the upper surface of the inner wall of the workbench 1. The sharpening plate 48 is rotatably connected to the groove on the positive surface of the slider 47. The left surface of the outer wall of the mounting frame 41 is fixedly connected to a magnet 43. The right surface of the sharpening plate 48 is fixedly connected to a magnetic strip 49. The electric push rod 3 drives the cutting knife 31 to move downward, and squeezes the sharpening plate 48, so that The left surface of the sharpening plate 48 is sharpened under the action of the cutting knife 31. The sharpening plate 48 moves rightward under the action of the cutting knife 31, so that the distance between the magnetic strip 49 and the magnet 43 is reduced, resulting in an increase in the magnetic force between the magnetic strip 49 and the magnet 43. Due to the magnetic repulsion between the magnetic strip 49 and the magnet 43, the sharpening plate 48 is prevented from over-turning during the sharpening of the cutting knife 31. The right end of the sharpening plate 48 is rotatably connected to the slider 47, and the spoiler 42 is rotatably connected to the groove on the right surface of the mounting frame 41. The mounting frame 41 A slide groove 44 is provided at the left end, and the outer wall of the slider 47 is slidably connected to the inner wall of the slide groove 44. A through column 45 is fixedly connected to the right end of the inner wall of the slide groove 44. A spring 46 is sleeved on the outer wall of the through column 45. The left end of the spring 46 is fixedly connected to the left surface of the slider 47, and the right end of the spring 46 is fixedly connected to the right surface of the inner wall of the slide groove 44. The spring 46 cooperates with the slider 47 to make the sharpening plate 48 have an elastic adjustment function in the horizontal direction, so that when the extrusion of the cutting knife 31 acts on the reaction force of the spring 46, the sharpening plate 48 is closely attached to the surface of the cutting knife 31. , which enhances the grinding effect of the grinding plate 48, ensures the service life and cutting effect of the cutting knife 31, and also plays a role in cleaning the outer wall of the cutting knife 31 during the grinding process of the cutting knife 31 by the grinding plate. At the same time, the blowing effect of the peripheral blowing device on the workbench 1 enables the spoiler 42 to guide the airflow onto the front surface of the cutting knife 31, cleans the debris remaining on the outer wall of the cutting knife 31, avoids the phenomenon that the rubber remains on the edge of the cutting knife 31 after cutting and causes the cutting surface to be uneven, and enhances the cutting effect of the device on the rubber rod.
[0034] Reference Figure 1 and Figure 5When the rubber rod is cut and transported, the positioning assembly 5 is started. The right surface of the workbench 1 is provided with a positioning assembly 5 near the right side of the material transport trough 12. The positioning assembly 5 includes a fixing seat 54. The rubber rod is inserted into the fixing seat 54 and placed in the material transport trough 12. The lower surface of the fixing seat 54 is fixedly connected to the right side of the right surface of the workbench 1 near the material transport trough 12. The left surface of the fixing seat 54 is fixedly connected with a rubber sleeve 55. The right surface of the fixing seat 54 is fixedly connected with a mounting seat 51. The interior of the mounting seat 51 is set as a hollow structure. The top corner of the outer wall of the mounting seat 51 is set as a rounded structure. During the cutting process, the outer wall clamping claw part of the rubber sleeve 55 wraps the rubber rod, so that the rubber sleeve 55 can gather and position the rubber rod, avoid the displacement of the rubber rod during cutting, and improve the accuracy of the device in cutting the rubber rod. The right surface of the mounting seat 51 is rotatably connected with a ring 52, and the right surface of the ring 52 is detachably connected with a rubber strip 53. The rubber strip 53 cooperates with the ring 52 to compensate for the stress of the bending part of the rubber rod during transportation, avoid the phenomenon of excessive bending of the rubber rod during the loading process and the breakage of the outer wall, and improve the protection of the rubber rod before cutting.
[0035] Working principle: During the cutting process of the cutting knife 31, the auxiliary component 4 is started, and the electric push rod 3 drives the cutting knife 31 to move downward, squeezing the grinding plate 48, so that the left surface of the grinding plate 48 is grinded under the action of the cutting knife 31, and the spring 46 cooperates with the slider 47 to make the grinding plate 48 have an elastic adjustment effect in the horizontal direction, so that when the squeezing effect of the cutting knife 31 is under the reaction force of the spring 46, the grinding plate 48 is close to the surface of the cutting knife 31, and the grinding plate 48 moves to the right, so that the distance between the magnetic strip 49 and the magnet 43 is reduced, resulting in an increase in the magnetic force between the magnetic strip 49 and the magnet 43. Due to the magnetic repulsion between the magnetic strip 49 and the magnet 43, the phenomenon of excessive flipping of the grinding plate 48 during the grinding process of the cutting knife 31 is avoided, thereby enhancing the grinding effect of the grinding plate 48, ensuring the service life and cutting effect of the cutting knife 31, and 31 is cleaned, and the outer wall of the workbench 1 is cleaned by the peripheral blowing device, so that the spoiler 42 directs the wind flow onto the front surface of the cutting knife 31, so as to avoid the rubber residue on the edge of the cutting knife 31 after cutting and causing the cutting surface to be uneven, thereby enhancing the cutting effect of the device on the rubber rod. When the rubber rod is cut and transported, the positioning component 5 is started, and the rubber rod is passed into the fixing seat 54 and then placed in the material transport trough 12. The rubber strip 53 cooperates with the ring 52 to compensate for the stress of the bending part of the rubber rod during transportation, so as to avoid the outer wall breakage caused by excessive bending of the rubber rod during the loading process. In the process of cutting the rubber rod, the outer wall clamping claw part of the rubber sleeve 55 wraps the rubber rod, so that the rubber sleeve 55 can gather and position the rubber rod, so as to avoid the displacement of the rubber rod during cutting, thereby improving the accuracy of the device in cutting the rubber rod.
