In a preferred embodiment of the present invention, the first transmission shaft is connected to the motor by a belt, and the drive shaft is connected to the screw shaft by a belt.

The present invention solves the defect existing in the background technology, and the present invention has the following beneficial effects:

Through the action of the toggle mechanism, the position of the driving gear can be changed between the first gear and the second gear, which plays the role of changing the meshing object of the driving gear. At the same time, because the first gear and the second gear rotate in opposite directions, it is guaranteed After the drive gear changes the meshing object, the drive shaft changes the direction of rotation.

The rotation direction of the drive shaft and the toggle direction of the toggle mechanism just form a linkage structure. When the drive gear meshes with the first gear, the toggle mechanism is driven by the drive shaft so that the toggle mechanism has a tendency to turn the drive gear to the second gear. And power, and the final drive gear is separated from the first gear, and driven by the gravitational potential energy of the balance plate on the swing bar to mesh with the second gear; otherwise, when the drive gear meshes with the second gear, the toggle mechanism will make the drive gear move in the opposite direction .

On the one hand, the structure of the feather key can ensure that there is a clamp limit along the circumference of the drive shaft between the drive gear and the drive shaft, so that the drive gear will not move relative to the drive shaft along the circumference; on the other hand, the drive gear can move along the drive shaft. The axial sliding ensures that the drive gear moves between the first gear and the second gear.

The two shift fork rods are respectively located on both sides of the drive gear, and the drive gear can move axially along the drive shaft under the drive of the shift rod.

The set block can limit the movement posture of the lever, and the stopper can limit the swing lever driven by the weight of the weight plate within a certain swing range, and then the movement range of the lever is also limited to ensure that the lever will not deviate excessively from left to right. Shift, only ensure that the drive gear changes the meshing distance between the first gear and the second gear.

When the driving gear meshes with the first gear, the pendulum shifts towards the side of the first gear. At this time, due to the gravity, the weight plate gives the pendulum a pulling force to the side of the deviation, and the screw sleeve is driven by the screw rod to move away from the first gear. The bent rod then pulls the sleeve into motion, at which point the sleeve rod will not slide relative to the sleeve due to the stop mechanism holding the sleeve rod in the sleeve until the swing rod is pulled beyond its vertical position and begins to move towards the second gear side At this time, the stop rod of the stop mechanism is pulled out for a distance by the second tensioned spring, so the sleeve rod slides relative to the sleeve until the sleeve rod is completely inserted into the sleeve, and the sleeve rod and sleeve at this time The sum of the lengths is the smallest, because the inertia screw sleeve continues to move, and due to the weight of the weight plate, the pendulum can push the lever to the side of the second gear, and finally push the drive gear to mesh with the second gear; then drive Because the drive gear meshes with the second gear, the shaft rotates in the opposite direction, so the movement of the screw sleeve is also reversed. At this time, the sleeve rod driven by the bending rod pushes the swing rod in the opposite direction, and then the driving rod is driven in the reverse direction, and the swing rod moves toward the second gear. The direction of the first gear deflects, and after crossing its vertical position, it shifts to the side of the first gear. At this time, due to the gravity of the counterweight plate, the swing rod pulls the sleeve rod out of the sleeve, and the length between the sleeve rod and the sleeve and the maximum, then the second spring tension becomes smaller, and the stop rod blocks the sleeve rod and the sleeve relatively fixedly.

During the left and right movement of the shift lever, the two shift levers continuously push the drive gear to move left and right along the drive shaft to change the meshing objects.

The first rotating shaft, the second rotating shaft and the third rotating shaft cooperate with each other, so that the pendulum can rotate with the third rotating shaft as the center of a circle, drive the driving lever to move left and right, and then drive the shift fork lever to follow the shift rod to move left and right.

When the pendulum is biased to the first gear side, the pendulum is in the vertical state, and the pendulum has just crossed the vertical state and is deflected to the second gear side for a distance of two shift fork rod margins, the stop rod is stuck on the sleeve. Rod and sleeve; after the pendulum is biased to the second gear for a certain distance, the stretching length of the second spring becomes larger and larger, and the stop rod is pulled out for a certain distance at this time, and the sleeve rod can slide relative to the sleeve.

The setting of the stopper ensures that the lower end of the swing rod will not deviate beyond the range, that is, the swing rod will not make the moving range of the shift rod too large.

The screw drives the structure of the screw sleeve, and then the screw sleeve provides the power source for the toggle mechanism. Since the rotation direction of the screw is related to the meshing object of the drive gear, the movement direction of the screw sleeve is related to the rotation direction of the drive shaft, and the rotation direction of the drive shaft The direction of rotation is controlled by the toggling mechanism; thus, the above-mentioned process forms a cyclic motion process of mutual influence, and the toggling mechanism and the driving mechanism continuously affect the continuous cyclic control.

The distance between the two shift fork rods is greater than the axial length of the drive gear, which can provide inertial buffering for the reverse movement of the drive gear.

The distance between the two shift fork rods is greater than the axial length of the drive gear, and the length longer than the drive gear is the margin of the distance between the two shift fork rods relative to the length of the drive gear. Due to the existence of the above margin, the swing rod is in the vertical position In the normal state, the two shift fork levers will not be blocked by the drive gear, and the swing lever only needs to rely on inertia when it crosses its vertical state.

The transmission gear is coaxial with the first gear, and the second gear meshes with the transmission gear to realize the reverse rotation of the first gear and the second gear.

The first spring on the stop mechanism can reset the displaced stop lever in time.

Through the transmission function of the driving mechanism, the purpose of transmitting the power of the motor to the screw rod is realized; at the same time, through the function of the toggle mechanism, the meshing object of the driving gear can be changed, thereby realizing the forward and reverse rotation of the screw rod.

Through the forward and reverse rotation of the screw rod, the screw sleeve realizes the reciprocating movement of the scraper along the axis of the screw rod, so that the scraper can spread (the powder spread on the supporting plate) on the carrier (such as braided Cloth), and along with the carrier along the direction perpendicular to the screw rod, slowly pass the powder above the pallet and evenly scrape it off.

The rotating shaft of the supporting plate is set on the screw rod. Due to gravity, the supporting plate can always be located under the screw rod, so that the supporting plate can assist the scraper to spread the powder.

One end of the drive shaft 4 is provided with a screw rod 10, and the screw sleeve 11 connected to the bent rod 12 is threaded on the screw rod 10; the screw rod 10 drives the structure of the screw sleeve 11, and then the screw sleeve 11 provides a power source for the toggle mechanism. The direction of rotation is related to the meshing object of the drive gear 3, so the direction of motion of the screw sleeve 11 is related to the direction of rotation of the drive shaft 4, and the direction of rotation of the drive shaft 4 is controlled by the toggle mechanism; During the cycle movement process, the toggle mechanism and the drive mechanism continuously affect the continuous cycle control.

The first gear 1 and the transmission gear 6 are coaxially arranged on the first transmission shaft 34, the second gear 2 is arranged on the second transmission shaft 35, the first transmission shaft 34 is arranged in parallel with the second transmission shaft 35, and the second gear 2 Mesh together with transmission gear 6, power unit is motor 36, and one end of screw rod 37 is coaxially provided with screw rod shaft. Through the transmission effect of the driving mechanism, the power of the motor 36 is delivered to the screw rod 37; at the same time, through the action of the toggle mechanism, the meshing object of the driving gear 3 can be changed, and then the forward and reverse rotation of the screw rod 37 can be realized.

The first drive shaft 34 is connected to the motor 36 by a belt 38, and the drive shaft 4 is connected to the screw shaft by the belt 38. The belt pulley on the motor 36, the belt pulley on the first transmission shaft 34, the belt pulley on the drive shaft 4 and the belt pulley on the screw rod shaft have played the role of motor 36 speed reduction through the transmission of two belts 38, and the screw rod shaft speed is reduced. The motor 36 that the present invention adopts is also a low-speed motor.

A supporting plate 43 is arranged under the screw rod 37 , and the two ends of the supporting plate 43 are sleeved on the corresponding two ends of the screw rod 37 through the rotating shaft. The spiral sleeve 41 realizes the reciprocating circular movement of the scraper 42 along the axis direction of the screw rod 37 through the positive and negative rotation of the screw rod 37, so that the scraper 42 can flatten the powder (spread on the top of the pallet 43) Spread on the carrier (such as woven cloth), and along with the carrier along the direction perpendicular to the screw rod 37, slowly pass the powder above the supporting plate 43 and evenly scrape it off. The rotating shaft of the supporting plate 43 is arranged on the screw rod 37. Due to gravity, the supporting plate 43 can always be located under the screw rod 37, so that the supporting plate 43 can assist the scraper 42 to spread the powder.

The first rotating shaft 16, the second rotating shaft 17 and the third rotating shaft 18 are arranged in turn on the swing rod 15, the swing rod 15 is connected to the shift lever 7 through the first rotating shaft 16, the swing rod 15 is connected to the sleeve rod 14 through the second rotating shaft 17, and the sleeve rod 14 Coaxially socketed in the sleeve 13, the other end of the sleeve 13 is connected to the bent rod 12, and the swing rod 15 located at the second rotating shaft 17 is provided with a counterweight plate 19, and the swing rod 15 rotates through the third rotating shaft 18; A stop mechanism 21 is provided on the barrel 13 , and the stop mechanism 21 can be buckled to limit the relative position between the sleeve rod 14 and the sleeve 13 . The first rotating shaft 16, the second rotating shaft 17 and the third rotating shaft 18 cooperate with each other, so that the swing rod 15 can rotate with the third rotating shaft 18 as the center of a circle, and drive the shift lever 7 to move left and right, and then drive the shift fork rod 8 to follow the shift rod 7 to move left and right .

Through the action of the toggle mechanism, the position of the driving gear 3 can be changed between the first gear 1 and the second gear 2, which plays the role of changing the meshing object of the driving gear 3. At the same time, due to the rotation of the first gear 1 and the second gear 2 The direction is opposite to ensure that the drive shaft 4 changes the direction of rotation each time the drive gear 3 changes the meshing object.

The rotation direction of the drive shaft 4 and the toggle direction of the toggle mechanism just form a linkage structure. When the drive gear 3 meshes with the first gear 1, the toggle mechanism is driven by the drive shaft 4 so that the toggle mechanism has the ability to turn the drive gear 3 to The inclination and power of the second gear 2, and the final drive gear 3 breaks away from the first gear 1, and drives to mesh with the second gear 2 by virtue of the gravity potential energy of the balance plate 19 on the swing bar 15; otherwise the drive gear 3 and the second gear 2 When engaged, the toggle mechanism will cause the drive gear 3 to move in reverse.

During the left and right movement of the shift lever 7, the shift fork lever 8 continuously pushes the drive gear 3 to move left and right along the drive shaft 4 through the two shift fork levers 8 to change the meshing object.

Three states when the fork 15 is biased toward the first gear 1 side, the fork 15 is in the vertical state and the fork 15 has just crossed the vertical state and deflected to the second gear 2 side for a section of two shift fork rods 8 margin distances, Both the stop rods 22 clamp the sleeve rod 14 and the sleeve 13; after the swing rod 15 is deflected to the second gear 2 for a certain distance, the stretching length of the second spring 24 becomes larger and larger, and the stop rod 22 is pulled out for a certain distance at this time, and the sleeve The rod 14 is slidable relative to the sleeve 13 .

When the driving gear 3 meshes with the first gear 1 , the pendulum 15 is biased toward the first gear 1 ; when the driving gear 3 is meshed with the second gear 2 , the pendulum 15 is biased toward the second gear 2 . When the driving gear 3 meshes with the first gear 1, the swing rod 15 is shifted towards the first gear 1 side, at this time, the weight plate 19 gives the swing rod 15 a pulling force to the side shifted to it due to gravity, and the screw sleeve 11 is The screw 10 is driven away from the first gear 1, and then the curved rod 12 pulls the sleeve 13 to move. At this time, because the stop mechanism 21 clamps the sleeve rod 14 in the sleeve 13, the sleeve rod 14 will not slide relative to the sleeve 13 until the swing rod 15 is drawn beyond its vertical position and begins to shift towards the second gear 2 side, at this time the stop lever 22 of the stop mechanism 21 is pulled out by the second spring 24 for a certain distance, so that the sleeve rod 14 is opposite to the sleeve 13 slides until the sleeve rod 14 is completely inserted into the sleeve 13, the sum of the lengths of the sleeve rod 14 and the sleeve 13 at this time is the smallest, because the inertia screw sleeve 11 continues to move, and due to the gravity of the counterweight plate 19, Fork 15 can push driving lever 7 to the second gear 2 one side, and finally pushes drive gear 3 to mesh with second gear 2; direction, so the movement of the screw sleeve 11 is also reversed. At this time, the sleeve rod 14 driven by the curved rod 12 pushes the swing rod 15 in the opposite direction, and then the shift rod 7 is driven in the reverse direction, and the swing rod 15 deflects toward the first gear 1 again, crossing the After its vertical position, it shifts to the first gear 1 side. At this time, due to the gravity effect of the counterweight plate 19, the swing rod 15 extracts the sleeve rod 14 from the sleeve 13, and the length of the sleeve rod 14 and the sleeve 13 The sum is the largest, then the pulling force of the second spring 24 becomes smaller, and the stop rod 22 blocks the sleeve rod 14 and the sleeve 13 to be relatively fixed.

The stop mechanism 21 comprises a stop bar 22 with a wedge-shaped head 25 at one end and a first spring 23 sleeved on the stop bar 22. The wedge-shaped head 25 of the stop bar 22 stretches into the sleeve 13, and the other end of the stop bar 22 stretches out of the sleeve. Outside the cylinder 13, two ends of the first spring 23 are respectively fixed on the outer wall of the sleeve 13 and the stop rod 22. The first spring 23 on the stop mechanism 21 can reset the displaced stop rod 22 in time.

One end of the second spring 24 is fixedly arranged, and the other end is connected to one end of the stop rod 22 .

When the second spring 24 is tightened, the wedge-shaped head 25 is out of contact with the sleeve rod 14 in the sleeve 13 , and the swing rod 15 can insert or pull the sleeve rod 14 into or out of the sleeve 13 due to the gravitational potential energy of the counterweight plate 19 .

Both sides of the free end of the swing rod 15 are respectively provided with a stopper 20 . The setting of the stopper 20 ensures that the lower end of the swing rod 15 will not deviate beyond the range, that is, the swing rod 15 will not cause the shifting rod 7 to move too far.

The distance between the two shift fork rods 8 is greater than the axial length of the drive gear 3, which can provide inertia buffering for the reverse movement of the drive gear 3, and the distance between the two shift fork rods 8 is greater than the axial length of the drive gear 3. Length, longer than the length of the drive gear 3 is the length margin of the distance between the two shift fork levers 8 relative to the drive gear 3, due to the existence of the above margin, when the fork 15 is in a vertical state, the two shift fork levers 8 are not Can be blocked by drive gear 3, only need to get final product by virtue of inertia when fork 15 crosses its vertical state.

The two ends of the driving rod 7 are respectively slidably socketed on the respective corresponding sets of blocks 9. The sets of blocks 9 can limit the movement posture of the driving rod 7, and at the same time, the stoppers 20 can limit the swing rod 15 driven by the gravity of the weight plate 19 to a certain position. Within the swing range, the movement range of the driving lever 7 is also limited to ensure that the driving lever 7 will not deviate excessively from left to right, and only ensure that the driving gear 3 changes the meshing distance between the first gear 1 and the second gear 2 .

The driving gear 3 is arranged on the driving shaft 4 through the sliding key 5 , and the moving distance of the driving gear 3 on the sliding key 5 of the driving shaft 4 is the axial distance between the first gear 1 and the second gear 2 . On the one hand, the structure of the feather key 5 can ensure that there is a clamp limit between the drive gear 3 and the drive shaft 4 along the circumference of the drive shaft 4, so that the drive gear 3 will not move relative to the drive shaft 4 along the circumference; The driving gear 3 can slide along the axial direction of the driving shaft 4 to ensure that the driving gear 3 moves between the first gear 1 and the second gear 2 .

The first gear 1 is coaxially connected with the transmission gear 6 , and the transmission gear 6 meshes with the second gear 2 . The transmission gear 6 is coaxial with the first gear 1 , and the second gear 2 meshes with the transmission gear 6 , realizing the reverse rotation of the first gear 1 and the second gear 2 .

The curved rod 12 is provided with a bolt locking device 32 at its corner, and the part of the curved rod 12 parallel to the drive shaft 4 can be inserted into the inner hole of the bolt locking device 32 and slide in the inner hole. The bolt locking device 32 The bolts on the top are screwed in and screwed out to control the tightness; by adjusting the relative position of the bent rod 12 and the bolt locking device 32, the position adjustment of the bent rod 12 to the shift fork rod 8 can be realized, so as to adjust the shifting of the shift fork rod 8 to the driving gear. timing.

The driving rod 7 can only move along the axial direction of the driving rod 7 itself under the restriction of the cover block 9, but the driving rod 7 cannot rotate along the axial direction of the driving rod itself in the cover block 9, so that the movement on the driving rod 7 is ensured. The fork lever 8 can not turn, and it is also guaranteed that the fork lever 8 can be moved to the drive gear 3 on its motion track.
