[0002] In the tobacco industry, the function of the cutter is to cut tobacco leaves and stems into leaf and stem fibers with a width that meets the requirements of the leaf processing specification, generally including a feeding system, a knife roll system, a knife grinding system, a transmission system, etc. The SD5 cutter is a new type of cutter with flexible processing concept developed by the Italian Garbuio Company, and is one of the main equipment for tobacco leaf processing. The knife grinding system is responsible for maintaining the sharpness of the cutter blade, thereby ensuring the quality and efficiency of the cutting. The grinding machine, as one of the key components of the knife grinding system, is installed upside down on the equipment through the base. When the grinding machine is in the operating position, it is inclined from top to bottom to the inside of the equipment, and the angle between the axis of the grinding machine and the vertical direction is preferably 15-20°.

[0003] The grinding of the grinding wheel will cause the grinding wheel to wear out. Generally, the grinding wheel needs to be replaced after the cutter runs continuously for 70-80 hours. The SD5 cutter is provided with fixed plates symmetrically arranged on both sides of the grinding machine. Installation grooves are formed in the base corresponding to the fixed plates. Pneumatic springs are arranged between the fixed plates on both sides of the grinding machine and the side walls of the installation grooves of the base. When replacing the grinding wheel, the locking member is loosened, and the grinding machine is manually pulled out of the base by the worker. The grinding machine swings to the outside of the equipment and is supported and positioned by the pneumatic spring. The angle between the axis of the grinding machine and the vertical direction is preferably 35-40° during replacement. Finally, appropriate tools (such as wrenches) are used to fix the adjusted position to ensure that the grinding machine remains stable during replacement.

[0004] The housing of the grinding machine of the SD5 cutter generally includes a bottom plate and a top protective cover, and a cylindrical housing is arranged between the two. Face plates and back plates are arranged on the front and rear sides of the cylindrical housing, and fixed plates are arranged on the left and right sides of the cylindrical housing.

[0029] As shown in Figures 1-7 The embodiments of the present application propose a grinding machine replacement auxiliary device of an SD5 tobacco cutter, which comprises a fixed cylinder 3 and a handle 4 arranged at the bottom of a panel 23. The fixed cylinder 3 is internally provided with a groove 31 and is open at both ends. The inner end of the fixed cylinder 3 is fixedly installed on the panel 23, and the outer end does not exceed the edge of the bottom plate 22. The axis of the fixed cylinder 3 is perpendicular to the panel 23. Such a structure design occupies a small space of the fixed cylinder 3 and does not affect the use of other structures. The handle 4 is T-shaped. The vertical section of the T-shaped handle 4 is a plug rod 42 inserted into the groove 31 of the fixed cylinder 3, and the horizontal section is a holding rod 41. A circular bracket 12 is fixedly arranged on the side wall of the base 1. When the handle 4 is not used, the handle 4 can be inserted into the bracket 12 for storage and management. At the same time, the free end of the insertion end of the handle 4 can be magnetically attracted to the side wall of the base 1 to avoid the handle 4 placed in the bracket 12 from rotating, and the handle 4 can be better stored.

[0030] A circular plate 35 capable of abutting against the insertion end of the handle 4 is slidingly installed in the groove 31 of the fixing cylinder 3, and an elastic member, which is a spring 36 in this embodiment, is installed between the circular plate 35 and the face plate 23. One end of the spring 36 is fixed to the face plate 23, and the other end of the spring 36 is fixed to the circular plate 35. When the handle 4 is inserted into the groove 31 of the fixing cylinder 3, the insertion end of the handle 4 abutting against the circular plate 35 under the elastic force of the spring 36.

[0031] A clamping block 43 is fixed to the outer wall of the free end of the insertion end of the handle 4, and a longitudinal sliding groove 32 matched with the clamping block 43 is arranged on the inner wall of the fixing cylinder 3, which is arranged along the axis direction of the fixing cylinder 3, and the clamping block 43 can slide along the axis direction of the fixing cylinder 3 in the longitudinal sliding groove 32. A circumferential clamping groove 33 matched with the clamping block 43 is arranged on the inner wall of the fixing cylinder 3 at the end of the longitudinal sliding groove 32, which is arranged along the circumference of the fixing cylinder 3 and only occupies a part of the complete circumference, and one end of the circumferential clamping groove 33 is communicated with the end of the longitudinal sliding groove 32, and the clamping block 43 can slide along the circumference of the fixing cylinder 3 in the longitudinal sliding groove 32.

[0032] When the grinding wheel needs to be replaced, the locking mechanism of the grinding machine 2 is released, the insertion end of the handle 4 is inserted into the groove 31 of the fixing cylinder 3, and the clamping block 43 is moved into the longitudinal sliding groove 32, and the clamping block 43 is moved along the longitudinal sliding groove 32, and in this process, the circular plate 35 always abuts against the insertion end of the handle 4 under the elastic force of the spring 36; when the clamping block 43 slides to the end of the longitudinal sliding groove 32, the handle 4 is rotated again, so that the clamping block 43 slides into the circumferential clamping groove 33, and the movement of the handle 4 and the fixing cylinder 3 in the axis direction is limited, so that the handle 4 and the fixing cylinder 3 are butted together. By such arrangement, the operation of butting the handle 4 into the fixing cylinder 3 is very simple, and the work efficiency is greatly improved.

[0033] A longitudinal clamping groove 34 is further arranged on the inner wall of the fixing cylinder 3, which is arranged along the axis direction of the fixing cylinder 3, and one end of the longitudinal clamping groove 34 is communicated with the end of the circumferential clamping groove 33 away from the longitudinal sliding groove 32, and the clamping block 43 can slide along the axis direction of the fixing cylinder 3 in the longitudinal clamping groove 34. When the clamping block 43 slides to the end of the circumferential clamping groove 33 away from the longitudinal sliding groove 32, the insertion end of the pull rope can slide into the longitudinal clamping groove 34 under the abutting action of the circular plate 35 and the spring 36, and the clamping block 43 can always remain in the longitudinal clamping groove 34 under the elastic force of the spring 36, so as to limit the movement of the clamping block 43 along the circumference and the axis direction of the fixing cylinder 3, thereby limiting the relative movement of the handle 4 and the fixing cylinder 3 and strengthening the butting effect. It should be noted that when the spring 36 is not under external force, the position of the circular plate 35 is between the longitudinal clamping groove 34 and the open end of the annular groove.

[0034] The side of the circular plate 35 away from the spring 36 is fixed with a buffer pad, which is specifically a rubber washer. When the handle 4 is inserted into the groove 31, the insertion end of the handle 4 can abut against the buffer pad, and the buffer pad replaces the circular plate 35 to contact the handle 4, thereby reducing the abrasion degree between the parts and prolonging the service life of the structure.

[0035] In the above embodiment, the outer end of the fixing cylinder 3 can be designed as a round corner structure (not shown in the figure), and by such a design, the handle 4 can be more smoothly inserted into the groove 31, thereby improving the work efficiency.

[0036] In the above embodiment, the number of the clamping blocks 43 fixed on the insertion end of the handle 4 is two, and the number of the longitudinal sliding grooves 32, the circumferential clamping grooves 33 and the longitudinal clamping grooves 34 formed on the inner side wall of the fixing cylinder 3 is also two. By such a design, the tightness of the connection between the handle 4 and the fixing cylinder 3 can be enhanced.

[0037] The holding rod 41 is provided with an anti-skid sleeve (not shown in the figure), which facilitates the workers to exert force. In the embodiment, the holding rod 41 has a certain length, and the workers can exert force at different positions during the process of pulling out the grinder 2, and the effect of pulling out the grinder 2 is better.

[0038] The grinder 2 replacement assisting device of the SD5 tobacco cutter further comprises a abutting rod 251 rotatably installed at the middle part of the outer side of the fixing plate 25, and a damping block is arranged at the rotatable connection between the abutting rod 251 and the fixing plate 25. A abutting block 11 is fixedly arranged on the side wall of the base 1 corresponding to the abutting rod 251. Specifically, the abutting block 11 is provided with an abutting groove, and when the grinder 2 is swung to the replacement position outside the base 1, the abutting block 11 can be abutted against the side wall of the abutting groove by rotating the abutting block 11, so as to fix the position of the grinder 2 and ensure the stability of the grinder 2 during the replacement process. The structure is simple and convenient to operate. A limiting plate 252 is arranged on the top of the fixing plate 25, and the abutting rod 251 is magnetically connected with the limiting plate 252. When the abutting rod 251 is not used, the abutting rod 251 is magnetically connected on the limiting plate 252, which facilitates the management of the abutting rod 251.

[0039] Working principle:

[0040] When the grinding wheel needs to be replaced, the locking mechanism of the grinding machine 2 is unlocked, the handle 4 is taken out of the support 12, the insertion end of the handle 4 is inserted into the groove 31 of the fixed cylinder 3 and the handle 4 is rotated until the clamping block 43 enters the longitudinal clamping groove 34, the worker slowly pulls out the grinding machine 2 from the base 1 through the handle 4, and finally swings the grinding machine 2 to the outside of the base 1 to an angle of 35-40° between the axis of the grinding machine 2 and the vertical direction under the auxiliary supporting and positioning of the pneumatic spring 36 (not shown in the figure), the worker can obtain a better view and a replacement posture at this angle, at this time, the abutting rod 251 is rotated and abuts on the abutting block 11, the position of the grinding machine 2 is fixed, and the worker can replace the grinding wheel, in the replacement process, the handle 4 can be taken out by pressing the circular plate 35 and then reversing the handle 4, since the grinding wheel is usually replaced in cooperation with the auxiliary grinding wheel replacement tool, and the auxiliary grinding wheel replacement tool is usually temporarily fixed at the position of the bottom plate 22 of the grinding machine 2, the handle 4 is temporarily removed, and the mutual interference between the grinding wheel replacement tool and the handle 4 can be avoided. After the replacement is completed, the grinding machine 2 is pulled outwards by a certain angle, the abutting rod 251 is rotated and magnetically attracted to the limiting plate 252, the grinding machine 2 is put back into the base 1 through the handle 4, and is locked and fixed, and finally the handle 4 is removed and put into the support 12.
