Description

Technical Field

[0001] The utility model relates to the technical field of shredders, in particular to a double-air-port cleaning device for shredders. Background Art

[0002] A shredder is a device that cuts leaves or stems into shreds of a certain width. It is divided into rotary shredders, roller shredders, and top-and-bottom shredders. A shredder is provided with a shredder. Each blade of the shredder has an inner concave surface. After shredding, shredded tobacco will remain in the inner concave surface, which needs to be cleaned with an air blowing device.

[0003] However, the single blowing port currently used cannot completely clean the inner concave surface, that is, after cleaning, tobacco shreds may still remain on the concave surface, resulting in low cleaning efficiency. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a dual air port cleaning device for a shredder, so as to solve the problem pointed out in the background technology that the existing single air port cannot completely clean the inner concave surface, thus resulting in low cleaning efficiency.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] A double air port cleaning device for a wire cutter comprises a box body and a wire cutter, wherein the wire cutter is rotatably installed in the box body, a motor is provided on one side of the box body, an output shaft of the motor is fixedly connected to the wire cutter, a hollow rod is provided in the box body, an upper air blowing groove and a lower air blowing groove are provided on the hollow rod, an air pump is provided at one end of the hollow rod, and a connecting rod is provided at the other end, a first transmission assembly and a second transmission assembly are sequentially sleeved on the connecting rod, and the first transmission assembly or the second transmission assembly is respectively used for reversing or forwarding the connecting rod.

[0007] Furthermore, the first transmission assembly includes a first driving gear and a first driven gear, the first driving gear is sleeved on the output shaft of the motor, the first driven gear is sleeved on the connecting rod, and the first driving gear and the first driven gear are meshed with each other. In this way, when the device is working, the motor is started, the output shaft of the motor drives the first driving gear to rotate, and the first driving gear then drives the connecting rod to rotate in the opposite direction through the first driven gear, thereby achieving the effect of driving the hollow rod to rotate in the opposite direction.

[0008] Furthermore, the second transmission assembly includes a second driving gear and a second driven gear, the second driving gear is sleeved on the output shaft of the motor, a steering gear is meshed on one side of the second driving gear, the steering gear and the second driven gear are meshed with each other, and the second driven gear is sleeved on the connecting rod. In this way, when the device is working, the motor is started, the output shaft of the motor drives the second driving gear to rotate, and the second driving gear drives the connecting rod to rotate accordingly through the steering gear and the second driven gear, thereby achieving the effect of driving the hollow rod to rotate.

[0009] Furthermore, the teeth on the first driving gear and the second driving gear are arranged in an interlaced manner. In this arrangement, teeth are arranged at one section along the circumferential distance of the first driving gear and the second driving gear, and a smooth surface is arranged at another section. When the teeth on the first driving gear mesh with the teeth on the first driven gear, the teeth on the second driving gear do not contact the teeth on the steering gear. At this time, the smooth surface on the second driving gear contacts the steering gear, and it cannot drive the steering gear to rotate accordingly; on the contrary, when the second driving gear can drive the steering gear to rotate, the smooth surface on the first driving gear contacts the first driven gear, and it cannot drive the first driven gear to rotate accordingly, thereby achieving the effect of reciprocating the hollow rod.

[0010] Furthermore, a slider is fixedly connected to the free end of the connecting rod, and a slide groove is provided on one side of the box body, and the slider is slidably connected in the slide groove. This arrangement is used to slide and adjust the positions of the first driven gear and the second driven gear.

[0011] Furthermore, a positioning block is fixedly connected to one side of the slide slot, a positioning hole is provided on the positioning block, a through hole is provided on the slider, and a positioning pin is provided on the slider. In this way, when the device is working, one end of the positioning pin contacts one end of the positioning block, so that the slider cannot move backward along the slide slot, thereby achieving the purpose of fixing the slider; when the device is not working, the positioning pin, the positioning hole and the through hole cooperate with each other to achieve the purpose of fixing the slider, thereby preventing the first driven gear and the second driven gear from moving at will.

[0012] Furthermore, one end of the hollow rod is fixedly connected to a connecting pipe, and the free end of the connecting pipe is fixedly connected to the air pump. In this way, when the device is working, the air pump is started to pass gas into the hollow rod to provide a power source for the upper blowing groove and the lower blowing groove.

[0013] Furthermore, a first bearing is clamped between the hollow rod and the connecting pipe. In this way, when the hollow rod rotates, the connecting pipe is not affected by the first bearing, so that the connecting pipe can be used normally; at the same time, the friction between the hollow rod and the connecting pipe is reduced, and the wear of the hollow rod and the connecting pipe is reduced.

[0014] The utility model has the following advantages:

[0015] 1. Through the cooperation of the hollow rod, the upper air blowing groove, the lower air blowing groove, the first transmission assembly and the second transmission assembly, the upper air blowing groove and the lower air blowing groove form a certain angle, and rotate at a certain angle with the hollow rod, so that the tobacco shreds remaining in the concave surface of the blade of the cutter are cleaned back and forth on the cutter to prevent the existence of cleaning dead corners, thereby solving the problem that the existing single air blowing port cannot completely clean the inner concave surface, resulting in low cleaning efficiency;

[0016] 2. Through the mutual cooperation of the first driving gear, the first driven gear, the second driving gear, the second driven gear and the steering gear, the upper blowing groove and the lower blowing groove can rotate relative to the shredder, and reset when the concave surface of the next shredder reaches the cleaning position, that is, the hollow rod is reset, and then the upper blowing groove and the lower blowing groove are reset;

[0017] 3. Through the cooperation of the slide groove, the slider, the positioning block and the positioning pin, it is convenient to adjust the specific positions of the first driven gear and the second driven gear, that is, to adjust the use state of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1-2 As shown, the present application discloses a double-air-port cleaning device for a shredder, comprising a box body 1 and a shredder 11. The shredder 11 is rotatably mounted in the box body 1. A mounting seat 2 is fixedly mounted on one side of the box body 1 by bolts. A motor 12 is fixedly mounted on the mounting seat 2 by bolts. The output shaft of the motor 12 is key-connected with the shredder 11. A hollow rod 3 is rotatably mounted in the box body 1. An upper air blowing groove 31 and a lower air blowing groove 32 are provided on the hollow rod 3. The upper air blowing groove 31 and the lower air blowing groove 32 form a At a certain angle, one end of the hollow rod 3 is rotatably connected with a connecting tube 33, and the free end of the connecting tube 33 is threadedly connected to the air pump. When the device is working, the air pump is started to pass gas into the hollow rod 3, and then two wind blades are formed through the upper blowing groove 31 and the lower blowing groove 32, and they rotate in opposite directions with the blade of the shredder 11 to clean the remaining tobacco on the shredder 11, solving the problem that the existing single blowing port cannot completely clean the inner concave surface, resulting in low cleaning efficiency. In fact, the motor 12 can be a servo motor or a reduction motor, but because the servo motor has higher response ability and more precise control than the reduction motor, the servo motor is preferably used in this embodiment.

[0026] like Figure 1-2As shown, in this embodiment, a first bearing is clamped between the hollow rod 3 and the connecting tube 33. When the hollow rod 3 rotates, the connecting tube 33 is not affected by the first bearing, so that the connecting tube 33 can be used normally; at the same time, the friction between the hollow rod 3 and the connecting tube 33 is reduced, and the wear of the hollow rod 3 and the connecting tube 33 is reduced. Second bearings 34 are clamped between both ends of the hollow rod 3 and the box body 1 to reduce the friction between the hollow rod 3 and the box body 1, so as to reduce the wear of the hollow rod 3 and the box body 1.

[0027] like Figure 3-4 As shown, one end of the hollow rod 3 is clamped with the connecting rod 4. In this embodiment, a clamping groove 42 is opened at one end of the hollow rod 3, and a clamping block 41 is welded at one end of the connecting rod 4. The hollow rod 3 and the connecting rod 4 are fixedly connected by the mutual cooperation of the clamping groove 42 and the clamping block 41, so that the connecting rod 4 can move axially along the hollow rod 3. The first transmission assembly and the second transmission assembly are sequentially sleeved on the connecting rod 4. The first transmission assembly or the second transmission assembly is used for reverse or forward rotation of the connecting rod, respectively.

[0028] In this embodiment, the first transmission assembly includes a first driving gear 5 and a first driven gear 51. The first driving gear 5 is fixedly sleeved on the output shaft of the motor 12 through a key connection, and the first driven gear 51 is fixedly sleeved on the connecting rod 4 through a key connection. The first driving gear 5 and the first driven gear 51 are meshed with each other. When the device is working, the motor 12 is started, and the output shaft of the motor 12 drives the first driving gear 5 to rotate. The first driving gear 5 then drives the connecting rod 4 to rotate in the opposite direction through the first driven gear 51, thereby achieving the effect of driving the hollow rod 3 to rotate in the opposite direction, so that the upper blowing groove 31 and the lower blowing groove 32 rotate in the same direction as the cutter 11, which is convenient for cleaning the remaining tobacco on the blade of the cutter 11.

[0029] like Figure 3-4 As shown, in this embodiment, the second transmission assembly includes a second driving gear 6 and a second driven gear 61, the second driving gear 6 is fixedly sleeved on the output shaft of the motor 12 through a key connection, a steering gear 62 is meshed on one side of the second driving gear 6, a fixing rod 63 is fixedly installed on one side of the box body 1 through bolts, the steering gear 62 is rotatably mounted on the free end of the fixing rod 63, the steering gear 62 and the second driven gear 61 are meshed with each other, and the second driven gear 61 is fixedly sleeved on the connecting rod 4 through a key connection. When the device is working, the motor 12 is started, and the output shaft of the motor 12 drives the second driving gear 6 to rotate, and the second driving gear 6 then drives the connecting rod 4 to rotate accordingly through the steering gear 62 and the second driven gear 61, thereby achieving the effect of driving the hollow rod 3 to rotate.

[0030] like Figure 1 and Figure 4As shown, in this embodiment, the teeth on the first driving gear 5 and the second driving gear 6 are arranged in an interlaced manner, that is, teeth are arranged at one section along the circumferential distance on the first driving gear 5 and the second driving gear 6, and a smooth surface is arranged at one section. When the teeth on the first driving gear 5 are meshed with the teeth on the first driven gear 51, the teeth on the second driving gear 6 do not contact the teeth on the steering gear 62. At this time, the smooth surface on the second driving gear 6 is in contact with the steering gear 62, and it cannot drive the steering gear 62 to rotate accordingly; conversely, when the second driving gear 6 can drive the steering gear 62 to rotate, the first driving gear 5 is in contact with the smooth surface on the first driving gear 5, and it cannot drive the first driven gear 51 to rotate accordingly, thereby achieving the effect of reciprocating the hollow rod 3.

[0031] like Figure 1 and Figure 3 As shown, the free end of the connecting rod 4 is fixedly connected to a slider 71 by bolts, a slide groove 7 is provided on one side of the box body 1, and the slider 71 is slidably connected in the slide groove 7. A positioning block 72 is welded on one side of the slide groove 7, a positioning hole is provided on the positioning block 72, a through hole is provided on the slider 71, and a positioning pin 73 is fixedly connected to the slider 71. When the device is working, one end of the positioning pin 73 touches one end of the positioning block 72, so that the slider 71 cannot move backward along the slide groove 7, thereby achieving the purpose of fixing the slider 71; when the device is not working, the positioning pin 73 and the positioning hole and the through hole cooperate with each other to achieve the purpose of fixing the slider 71, thereby preventing the first driven gear 51 and the second driven gear 61 from moving at will.

[0032] like Figure 4 As shown, in this embodiment, the spacing dimensions between the first driving gear 5 and the second driving gear 6, the first driven gear 51 and the second driven gear 61 are all greater than the thickness of the first driving gear 5. When cleaning is not required, the positioning pin 73 is manually pulled out, and then the slider 71 is moved backward along the slide groove 7, so that the first driving gear 5 and the first driven gear 51 are disengaged from each other, and the steering gear 62 and the second driven gear 61 are disengaged from each other, and then the slider 71 is fixed by the positioning pin 73 to prevent it from moving at will.

[0033] The method of using the utility model is as follows:

[0034] When in use, the servo motor is started, and the output shaft of the servo motor drives the first driving gear 5 and the second driving gear 6 to rotate forward. When the teeth of the first driving gear 5 mesh with the first driven gear 51, the first driving gear 5 drives the connecting rod 4 to rotate in the opposite direction through the first driven gear 51, thereby achieving the effect of driving the hollow rod 3 to rotate in the opposite direction, so that the upper blowing groove 31 and the lower blowing groove 32 rotate in the opposite direction with the shredder 11; when the teeth of the second driven gear 61 mesh with the steering gear 62, the second driving gear 6 drives the connecting rod 4 to rotate forward through the steering gear 62 and the second driven gear 61, thereby achieving the effect of driving the hollow rod 3 to rotate forward and completing the reset of the hollow rod 3. The upper blowing groove 31 and the lower blowing groove 32 form a certain angle, and rotate at a certain angle with the hollow rod 3, and circulate and clean the remaining tobacco in the concave surface of the blade of the shredder 11 on the shredder 11, preventing the existence of a cleaning dead angle, and solving the problem that the existing single blowing port cannot completely clean the inner concave surface, resulting in low cleaning efficiency.

[0035] When not in use, the positioning pin 73 is manually pulled out, and the slider 71 is moved backward along the slide groove 7, so that the first driving gear 5 and the first driven gear 51 are disengaged from each other, and the steering gear 62 and the second driven gear 61 are disengaged from each other, and then the slider 71 is fixed by the positioning pin 73 to prevent it from moving at will, that is, to prevent the first driven gear 51 and the second driven gear 61 from moving at will.
