Among them, the external driving motor drives the conveyor belt 2 to transport materials through the driving connector 3. The driving connector 3 is used to adjust the conveying frequency of the driving motor so that the conveyor belt 2 rotates intermittently, thereby facilitating the production and processing of moxibustion products.

Referring to Figures 3 and 8, in an optional embodiment: the connecting drive includes a fixed plate 71 and an import block 72 fixedly connected to the output shaft 7, a connecting shaft 73 is fixedly connected between the fixed plate 71 and the import block 72, the outside of the connecting shaft 73 is fixedly connected to a rotating drum bearing 74, the outside of the rotating drum bearing 74 is fixedly connected to a connecting sleeve 75, and a plurality of connecting shafts 73 are provided, which are distributed in a circular array between the fixed plate 71 and the import block 72.

It should be noted that a shift plate is fixedly connected to the output shaft 7 , the introduction block 72 is located between the shift plate and the fixed plate 71 , the movable cam 6 is slidably connected to the outside of the driving shaft 5 , and the movable cam 6 slides between the shift plate and the fixed plate 71 .

It should be noted that, referring to FIG. 3 , a smooth conical oblique groove is provided on one side of the guide block 72 close to the shift plate, so that the initial movable cam 6 can slide more stably between two adjacent connecting sleeves 75 .

Referring to Figures 3 to 7, in an optional embodiment: a plurality of movable cams 6 are provided, the number of the movable cams 6 is the same as the connecting shaft 73, the protrusions of any two adjacent movable cams 6 are staggered with each other, the staggered angle is adapted to the number of the connecting shafts 73, and the completely overlapped movable cams 6 and the connecting shafts 73 are in a fully meshed state.

It should be noted that the driving shaft 5 drives the output shaft 7 to rotate through the movable cam 6 and the connecting sleeve 75, wherein the connecting sleeve 75 and the movable cam 6 are both provided with six. When the six movable cams 6 are completely overlapped (refer to FIG. 6 ), the driving shaft 5 drives the output shaft 7 to rotate continuously and smoothly through the movable cam 6 and the connecting sleeve 75. When the six movable cams 6 are not completely overlapped (refer to FIG. 4 ) and are in a separated state, part of the movable cams 6 are in a meshing state with the connecting sleeve 75, and part of the movable cams 6 are located between the shift plate and the guide block 72. At this time, the driving shaft 5 drives the output shaft 7 to rotate intermittently through the movable cam 6 and the connecting sleeve 75.

The amplitude of the intermittent rotation is determined by the number of the movable cams 6 meshing with the connecting sleeve 75 .

By setting a certain number of movable cams 6 and connecting sleeves 75, it is convenient to control the engagement of different numbers of movable cams 6 and connecting sleeves 75, so as to achieve the effect of adjusting the intermittent rotation amplitude of the conveyor belt 2, so that the conveyor belt 2 has good adaptability when producing moxibustion products of different sizes and models, and each equipment of the moxibustion production line can reach the best working state, thereby effectively improving the production efficiency of moxibustion products.

Referring to Figure 3, in an optional embodiment: two driving shafts 5 are provided, and the proximal ends of the two driving shafts 5 are rotatably connected by a coupling, and the two driving shafts 5 are respectively provided on both sides of the main driving mechanism 4, and two groups of connecting drives are provided, and the two groups of connecting drive introduction blocks 72 are respectively adapted to the positions of the movable cams 6 sliding outside the driving shafts 5 on both sides, so that any movable cam 6 can be in meshing state with the introduction block 72.

It should be noted that by providing two groups of movable cams 6 and two groups of connecting sleeves 75, the effect of increasing the flexibility of adjusting the intermittent rotation amplitude is achieved. By controlling the engagement state of the two groups of movable cams 6 and the connecting sleeves 75, the amplitude change of the intermittent rotation can be adjusted more flexibly, thereby effectively improving the use effect of the device and being able to adapt to the production needs of moxibustion products of different sizes.

6 and 7 , in an optional embodiment: the outside of the movable cam 6 is fixedly connected to a positioning block 61, the outside of the positioning block 61 is rotatably connected to a movable ring 62, the outside of the movable ring 62 is fixedly connected to a connecting rod 63, the connecting rod 63 penetrates and is slidably connected to the outside of the driving connector 3, and the connecting rod 63 is used to adjust the movable cam 6 and the introduction block 72 to be in an engaged state or a disengaged state.

It should be noted that when the position of the movable cam 6 needs to be adjusted, it is achieved by pushing the connecting rod 63 .

When the connecting rod 63 is pushed, the connecting rod 63 drives the positioning block 61 to move through the movable ring 62 , and the positioning block 61 drives the movable cam 6 to slide outside the driving shaft 5 .

9 and 10 , in an optional embodiment: the main drive mechanism 4 includes a main drive wheel 41 rotatably connected to the inside of the inner support ring 31, and also includes a driving gear 43 fixedly connected to the ends of the two driving shafts 5, a connecting gear 44 is meshedly connected between the driving gear 43 and the half gear ring 42, and the connecting gear 44 is rotatably connected to the inner side of the inner support ring 31, and the main drive wheel 41 is connected to an external drive motor through a transmission belt.

It should be noted that both sides of the main driving wheel 41 are rotatably connected to the inner support ring 31, and the inner support ring 31 seals both sides of the main driving wheel 41, so that the interior of the main driving wheel 41 forms a sealed driving cavity, and the two sets of connecting gears 44 and the driving gear 43 are both located in the driving cavity. The two driving shafts 5 both penetrate the inner support ring 31 and are rotatably connected between the corresponding inner support ring 31 and the driving connector 3.

In an optional embodiment, the rotation travel ratio of the main driving wheel 41 and the driving gear 43 is two to one. When the main driving wheel 41 rotates one circle, the main driving wheel 41 drives the driving gear 43 to rotate one circle through the half gear ring 42 and the connecting gear 44.

The axis center of the connecting gear 44 meshing with the two driving gears 43 is coplanar with the axis centers of the main driving wheel 41 and the driving shaft 5 .

It should be noted that when the main driving wheel 41 rotates continuously, the main driving wheel 41 drives the semi-toothed ring 42 and the two connecting gears 44 to rotate respectively, and when the semi-toothed ring 42 enters and the connecting gear 44 disengages and engages with the connecting gear 44, the semi-toothed ring 42 just drives the driving gear 43 to rotate one circle through the connecting gear 44.

Therefore, when the main driving wheel 41 rotates continuously, the main driving wheel 41 drives the connecting gear 44 to rotate through the half gear ring 42, the connecting gear 44 drives the driving gear 43 to rotate, the driving gear 43 drives the driving shaft 5 to rotate, and the two driving shafts 5 are in an alternating single-circle rotation state.

It should be noted that a pulley for installing a transmission belt is provided on the outside of the main driving wheel 41. During installation, it can be installed by separating the driving shaft 5 and the inner support ring 31 on either side. The inner support ring 31 can be composed of a detachable cover plate and a guard ring, which are fixed by bolts.

It should be noted that the main driving wheel 41 can also be connected to an external driving motor via a chain or a gear.

Referring to Figures 11 and 12, in an optional embodiment: the outside of the driving connector 3 is fixedly connected to a limited fixing block 9, a positioning slot 91 is provided on the top of the limited fixing block 9, a sliding block 8 is fixedly connected to the top of the connecting rod 63, the sliding block 8 is slidably connected to the outside of the limited fixing block 9, a plug-in block 81 is plugged into the inside of the sliding block 8, a positioning spring 82 is provided between the plug-in block 81 and the sliding block 8, and the size of the pin of the plug-in block 81 is adapted to the size of the positioning slot 91.

It should be noted that the slide block 8 is fixed by inserting the plug-in block 81 into the positioning slot 91 , thereby fixing the connecting rod 63 , thereby ensuring the external position stability of the movable cam 6 on the driving shaft 5 .

Wherein, when the movable cam 6 is in an engaged state with the connecting sleeve 75 or in a disengaged state with the connecting sleeve 75 , the limiting fixing block 9 is provided with a positioning slot hole 91 for fixing the sliding block 8 .

The working process of the above embodiment is as follows: during the working process, the external drive motor drives the main drive wheel 41 to rotate through the transmission belt, and the main drive wheel 41 drives the half gear ring 42 to rotate, and the half gear ring 42 alternately enters into a meshing state with the two connecting gears 44, so that the two driving shafts 5 are in an alternating single-circle rotation state.

The two driving shafts 5 drive the output shaft 7 to rotate alternately through the movable cam 6 and the connecting sleeve 75. The output shaft 7 drives the conveyor belt 2 to rotate through the driving roller of the conveyor belt 2. The production and feeding of moxibustion products are carried out through the conveyor belt 2.

When it is necessary to replace moxibustion products of different sizes and models, the conveying speed and intermittent amplitude of the conveyor belt 2 need to be adjusted synchronously, wherein the conveying speed of the conveyor belt 2 can be directly achieved by controlling the rotation speed of the driving motor, which will not be described in detail in the present invention, wherein the conveying intermittent amplitude of the conveyor belt 2 is controlled by the driving connector 3.

Wherein, referring to Figure 3, when the movable cams 6 on the left and right sides are completely overlapped and meshed with the connecting sleeve 75, the driving shaft 5 drives the output shaft 7 to rotate continuously and smoothly, and when the outer part of a group of movable cams 6 on the left side is controlled to disengage and mesh with the connecting sleeve 75 on the left side, the output shaft 7 is driven to rotate intermittently when the left driving shaft 5 rotates, and the output shaft 7 is driven to rotate continuously when the right driving shaft 5 drives it to rotate. Since the rotation of the left driving shaft 5 and the right driving shaft 5 is in a continuous alternating single-turn rotation state, when the output shaft 7 rotates, its pause interval is the rotation gap of the movable cam 6 from which the left driving shaft 5 is disengaged.

3 , when the movable cam 6 of the left driving shaft 5 is completely disengaged from the connecting sleeve 75 , only the right driving shaft 5 drives the output shaft 7 to rotate, and the rotation stop interval of the output shaft 7 is the rotation interval of the left driving shaft 5 .

Similarly, when the movable cam 6 of the left driving shaft 5 is disengaged from the meshing state of the left connecting sleeve 75, the number of disengagements of the movable cam 6 of the right group is increased, and the stop interval of the output shaft 7 is further increased.

Therefore, the intermittent rotation of the output shaft 7 driven by the active shafts 5 on both sides is controlled by the disengaged active cams 6, so as to achieve the effect of conveniently adjusting the intermittent rotation amplitude of the output shaft 7. By connecting the output shaft 7 and the driving roller of the conveyor belt 2, the effect of adjusting the intermittent conveying amplitude of the conveyor belt 2 is achieved. By setting two sets of active cams 6, the flexibility of the adjustable intermittent rotation of the output shaft 7 is further increased, thereby effectively ensuring the feeding effect of the device.

Compared with increasing the number of movable cams 6 and the number of connecting sleeves 75 matched thereto on the outside of the active shaft 5 on one side, by setting two groups of movable cams 6 and connecting sleeves 75 symmetrically on the left and right, the number of movable cams 6 and connecting sleeves 75 on one side is effectively reduced, thereby effectively increasing the strength of the meshing connection area of the movable cams 6 and connecting sleeves 75, thereby effectively protecting the axial diameter of the connecting shaft 73, effectively ensuring the strength of the single group of movable cams 6, the connecting shaft 73 and the connecting sleeve 75, and thus effectively ensuring the overall service life of the device.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
