For the belt rotating mechanism 2, the belt rotating mechanism is an independent structure and can move according to the process requirements, on one hand, the feeding operation of the triangular belt is completed, and on the other hand, the triangular belt needs to be moved to a vulcanization station for vulcanization treatment. For this purpose, as shown in fig. 8-10, the belt rotating mechanism 2 includes a first sliding cart 21, a second sliding cart 22, a second frame 23, and two feeding assemblies 24, the first sliding cart 21 is provided with a first sliding rail 211, the second sliding cart 22 is slidably provided on the first sliding rail 211, two sides of the second frame 23 are respectively provided with the feeding assemblies 24, the feeding assemblies 24 include a third driving mechanism 241, two second swing arms 242, and two parallel grooved rollers 243, the grooved rollers 243 are provided on the corresponding second swing arms 242, and the third driving mechanism 241 is configured to drive the two second swing arms 242 to swing on the second frame 23.

Specifically, after the v-belt is sleeved between the two corresponding grooved rollers 243 on both sides of the second frame 23, the v-belt is tensioned by the two grooved rollers 243, then the first sliding carriage 21 can be moved toward the vulcanizing station by power driving, and after moving to the vulcanizing station, the second sliding carriage 22 will be moved toward the vulcanizing mechanism 3 at the vulcanizing station, so that the v-belt enters the vulcanizing mechanism 3 for vulcanization. Thus, a plurality of belt rotating mechanisms 2 can be arranged to be used in cooperation with the vulcanizing mechanism 3.

When the V belt on one of the belt rotating mechanisms 2 is vulcanized, the other belt rotating mechanism 2 can perform feeding installation of the V belt, and then the vulcanizing mechanism 3 at the vulcanizing station is not needed to wait, so that the time is effectively saved and the production efficiency is improved.

In order to conveniently feed the V-belt on the belt rotating mechanism 2 into the vulcanizing mechanism 3, the second frame 23 comprises a base 231, two sliding frames 232 and two drivers 233, wherein the cross section of the base 231 is a U-shaped structure, the sliding frames 232 are arranged opposite to and arranged at the ends of the base 231, and the drivers 233 are used for driving the sliding frames 232 to slide on the base 231; the carriage 232 is provided with the feeding assembly 24, and the grooved rollers 243 are extended toward the opening direction of the base 231.

Specifically, the base 231 of the second frame 23 is of a U-shaped structure, so that when the second trolley moves to the vulcanizing mechanism 3, the vulcanizing mechanism 3 can be inserted into the U-shaped base 231, so that the two sliding frames 232 can be arranged on two sides of the vulcanizing mechanism 3, and the requirement that the triangular belt enters the vulcanizing mechanism 3 for vulcanization treatment is met. Meanwhile, the two sliding frames 232 can be driven by the drivers 233 respectively correspondingly arranged to slide on the base 231 relatively, so as to adjust the distance between the two sliding frames 232 to meet the requirement of the vulcanization processing of the V-belt. For the representation entity of the driver 233, a mode of matching a motor with a screw rod can be adopted, correspondingly, a threaded hole is formed in the sliding frame 232, the screw rod is in threaded connection with the threaded hole, and the motor drives the screw rod to rotate so as to drive the sliding frame 232 to move.

In addition, for the third driving mechanism 241, the representation entity may be an electric push rod, an air cylinder or an oil cylinder, and the like, which is not limited and described herein.

Further, in order to facilitate the rotation of the grooved rollers 243, so as to enable the V-belt thereon to rotate circularly, a driving motor 234 is arranged on one of the sliding frames 232, the driving motor 234 can drive the grooved rollers 243 arranged up and down to rotate through a chain, and further, during the vulcanization process, the grooved rollers 243 are rotated to enable different parts of the V-belt to enter vulcanization stations for vulcanization treatment.

In the preferred embodiment, one end of the grooved roller 243 needs to be suspended during the automatic feeding process, because the requirement of automatic feeding by the feeding mechanism 1 is satisfied. When the V-belt is driven to enter the vulcanizing mechanism 3 through the belt rotating mechanism 2, the requirement that a plurality of V-belts keep unified postures is met. For the grooved roller 243 with one suspended end, the belt is prone to be inclined due to the action of gravity and the pulling force of the V-belt, and the V-belt cannot enter the vulcanizing mechanism 3 accurately. For this purpose, a support base 25 is arranged on the sliding frame 232, the support base 25 is fixedly arranged on the sliding frame 232 and is located between two grooved rollers 243 in the same feeding assembly 24, a first support part 251 extending upwards is arranged at the free end of the support base 25, and a second support part 252 extending downwards is arranged at the free end of the support base 25.

Specifically, the support base 25 is fixedly installed at a side portion of the sliding frame 232 and is located between two of the grooved rollers disposed up and down, and when vulcanization is required, the two sliding frames 232 need to be separated from each other to tighten the v-belts wound around the two grooved rollers at the same height position. The grooved roller 243 is mounted at the upper end of the second swing arm 242 to effectively support the second swing arm 242, but at the end of the grooved roller 243 which is suspended, the grooved roller 243 is supported by the first support part 251 or the second support part 252 disposed on the support base 25 to hook the free end of the grooved roller 243, thereby ensuring that the free end of the grooved roller 243 is not bent by the tension of the v-belt, and improving the processing quality.

Specifically, in the actual use process, after the automatic feeding operation of the triangular belt is completed through the belt feeding mechanism 1, the triangular belt needs to be driven into the vulcanizing mechanism 3 through the belt rotating mechanism 2. At this time, the grooved rollers 243 are moved toward the corresponding support seats 25, and then, are slid relatively away by the sliding frame 232 to tension the V-belt. In the process of entering the vulcanizing mechanism 3, the entrance of the vulcanizing space in the opening state in the vulcanizing mechanism 3 is small, so that the V-belt tensioned on the grooved roller 243 needs to be ensured to maintain a high-precision levelness before entering the vulcanizing mechanism 3 accurately. For this, the positioning rod 262 is moved toward the corresponding support portion of the support base 25 by the positioning cylinder 261 to enable the free end portion of the grooved roller 243 to abut on the positioning rod 262. At this time, the third driving mechanism 241 drives the second swing arm 242 to rotate to the first position, and the end of the grooved roller 243 can ensure that the triangular belts on the two grooved rollers 243 at the same height position are kept in a horizontal state under the supporting and positioning action of the positioning rod 262, so as to ensure that the triangular belts can accurately enter the vulcanizing space of the vulcanizing mechanism 3. After the V-belt enters the vulcanizing space stably and accurately, the positioning rod 262 can be retracted to the original position, the third driving mechanism 241 drives the second swing arm 242 to rotate to the second position, so that the groove roller 243 abuts against the supporting seat 25, and the requirement of compressing the vulcanizing space of the vulcanizing mechanism 3 for vulcanizing is further met.

And through the configuration locating component 26, can make the unsettled setting of one end of grooved roll 243 in order to satisfy the requirement of carrying on through the automation of upper band mechanism 1, locating component 26 guarantees through locating lever 262 that the V belt enters into the in-process of vulcanization mechanism 3, keeps higher levelness to realize continuous automatic vulcanization operation.

In order to reduce the occurrence of uneven stress, the vulcanizing mechanism 3 employs a system in which two cylinders apply force to each other.

Specifically, the vulcanizing mechanism 3 is mounted on the ground through a base 31, and suspends a cross beam 33 through a column 32, and a lifting cylinder 35 and a pressing cylinder 36 are mounted on the cross beam 33.

Because the forces applied to the upper pressing plate 341 and the lower pressing plate 342 can be offset, the high-strength upright column 32 and the cross beam 33 are not needed to be used for supporting, and particularly for the cross beam 33, the weight of the cross beam 33 can be reduced by mainly bearing the gravity action generated by the components such as the lifting oil cylinder 35 and the lower pressing oil cylinder 36, and the manufacturing cost can be reduced.

Meanwhile, as the clamping plates 343 are respectively arranged in the upper and lower directions of the groove plates 344, and each groove plate 344 and the clamping plate are mutually matched to form an independent vulcanization space, the vulcanization treatment operation of the double-layer V-belt can be performed at one time, and the processing efficiency is further effectively improved.

Further, in order to facilitate automatic feeding and realize automatic feeding, so as to realize automatic loading and unloading of the vee belt, the lifting cylinder 35 includes a first sub cylinder 351 and a second sub cylinder 352 which are arranged on the cross beam 33, the first sub cylinder 351 is arranged close to the upright column 32, the second sub cylinder 352 is arranged far away from the upright column 32, a piston rod of the first sub cylinder 351 is connected with the lower pressing plate 342, and a piston rod of the second sub cylinder 352 is selectively connected with the lower pressing plate 342.

Specifically, the cantilever beam structure formed by the cross beam 33 and the upright column 32 is connected to the first sub-cylinder 351 near the end of the upright column 32 for the lower pressure plate 342, and is selectively connected to the second sub-cylinder 352 for the end of the lower pressure plate 342 far from the upright column 32.

The specific process is as follows: when feeding or discharging is needed, the piston rod of the second sub-cylinder 352 is disconnected from the lower pressing plate 342, and at this time, the outer ends of the upper pressing plate 341, the lower pressing plate 342, the clamping plate 343, and the two groove plates 344 are all in a suspended state, so that the triangular belt can enter between the groove plate 344 and the clamping plate from the outside, and can also be separated from between the groove plate 344 and the clamping plate, thereby completing feeding and discharging. When vulcanization is required, the piston rod of the second sub-cylinder 352 is connected to the lower press plate 342, and the two ends of the lower press plate 342 are respectively lifted up by the first sub-cylinder 351 and the second sub-cylinder 352, and are matched with the pressing action of the top upper press plate 341 to press and vulcanize the V-belt located between the clamp plate and the groove plate 344.

Similarly, when the two are separated from each other, the two snap-gauge 373 are driven to be away from each other through the locking cylinder 372, so that the snap-gauge contacts to limit the locking of the snap-gauge 3521, and the piston rod of the second sub-cylinder 352 can move upwards to separate the second sub-cylinder 352 from the lower press plate 342. Preferably, in order to avoid the unbalance of the force applied to the first sub-cylinder 351 when the piston rod of the second sub-cylinder 352 is separated from the lower pressing plate 342, a supporting column 311 may be disposed on the base 31, and the supporting column 311 is located below the heating assembly.

The second embodiment of the invention also provides a vulcanizing method of the V-belt, which is used for vulcanizing the V-belt by adopting the vulcanizing equipment, and comprises the following specific steps:

step 1, after the triangular belt to be processed is sleeved on the four transfer rollers, the first swing arm rotates to unfold the triangular belt through the four transfer rollers 1432. Specifically, when the upper belt assembly is in the initial position for manual belt loading, the first driving mechanism 142 drives the first swing arm 1433 to rotate, so that the two upper belt assemblies 143 are merged to the minimum position, and the distance between the four transfer rollers 1432 is minimum, so that an operator can easily sleeve the triangular belt on the four transfer rollers 1432 to complete the manual belt loading. After the manual feeding is completed, the first driving mechanism 142 drives the first swing arm 1433 to rotate reversely, so as to open the vee belt by using the four transfer rollers 1432.

And 2, driving the transfer roller to move towards the belt transfer mechanism by the sliding platform, and sleeving the triangular belt between the two grooved rollers 243. Specifically, after the triangular belt is manually sleeved on the four transfer rollers 1432, the belt feeding mechanism 1 can automatically feed the belt transfer mechanism 2 for belt feeding processing. In the case of the belt-rotating mechanism 2, the grooved rollers 243, which are located at the same height and are arranged oppositely, are close to each other, and the four transfer rollers 1432 will drive the v-belt to be sleeved on the grooved rollers 243 from the free end of the grooved rollers 243.

And 3, after the triangular belt on the transfer roller is sleeved on the two groove rollers, the sliding platform drives the transfer roller to leave the belt transfer mechanism. Specifically, after the sliding platform 12 is moved to the right position, the four transfer rollers 1432 are drawn close to each other, so that the v-belt is sleeved between the two grooved rollers 243 at the same height, and the v-belt is clamped in the corresponding groove on the grooved rollers 243. The specific process is as follows: the two sliding seats 1431 are close to each other under the driving action of the first driving mechanism 142, so that the v-belt is sleeved on the grooved rollers 243, and the two transfer rollers 1432 arranged up and down slide from the outer side of the corresponding grooved rollers 243 to the inner side, so that the sliding platform 12 can drive the upper belt assembly 143 on the mounting seat 13 to be separated from the belt rotating mechanism 2. In the case of the belt rotating mechanism 2, the grooved rollers 243 arranged up and down are provided, and therefore, the belt feeding operation can be performed twice by the belt feeding mechanism 1.

And 4, driving the second sliding trolley to move to the vulcanizing mechanism by the first sliding trolley, and then driving the V-belt to move between the clamping plate and the groove plate by the second sliding trolley. Specifically, after the tape loading process is performed by the tape loading mechanism 1 automatically feeding the tape rotating mechanism 2, the tape loading mechanism 1 is separated from the tape rotating mechanism 2. At this time, the first sliding trolley drives the moving to the vulcanizing mechanism 3, and then the V-belt arranged on the grooved roller 243 is sent to the vulcanizing mechanism 3 through the second sliding trolley.

And 5, the lifting oil cylinder and the pressing oil cylinder act to enable the triangular belt to be clamped between the clamping plate and the groove plate for vulcanization treatment. Specifically, after the v-belt is placed in the corresponding vulcanization space, the lifting cylinder 35 will drive the lower pressing plate 342 to move upward and drive the lower clamping plate 343 to extrude the groove plate 344, and the lower pressing cylinder 36 will drive the upper pressing plate 341 to move downward and drive the upper clamping plate 343 to extrude the groove plate 344. And the vulcanization space formed by the clamping plate 343 and the groove plate 344 is reduced, so that the V-belt is vulcanized. In the vulcanizing process, after the vulcanizing of the part of the V-belt located in the vulcanizing space is completed, the driving grooved roller 243 rotates to enable different parts of the V-belt to enter the vulcanizing space for vulcanizing.

In a preferred embodiment, in order to attach the label to the v-belt in advance before vulcanizing the v-belt, the step 3 further includes: after the sliding platform drives the transfer roller to leave the belt rotating mechanism, the label is adsorbed by the sucker and attached to the triangular belt. Specifically, after the triangular tape is automatically wound around the grooved roller 243 by the winding mechanism 1, the triangular tape can be labeled by the automatic labeling mechanism 4. In order to meet the requirement of automatic labeling in the process of automatically feeding the tape to the tape rotating mechanism 2 by the tape feeding mechanism 1, the two grooved rollers 243 at the lower positions are firstly subjected to tape feeding operation, after the labeling operation is completed, the two grooved rollers 243 at the higher positions are subjected to tape feeding operation, and then, the newly-fed V-belt is subjected to labeling operation.

Further, the step 4 further includes: before the second carriage drives the v-belt to move between the clamping plate and the groove plate, the positioning rod 262 is extended, and then the groove roller 243 moves toward the corresponding support seat 25 and abuts against the positioning rod 262. Specifically, the free end of the grooved roller 243 is positioned by the positioning rod 262, so as to ensure that the v-belt tensioned between the two grooved rollers 243 can keep a high horizontal state, and ensure that the v-belt can accurately slide into the vulcanization space when the second sliding trolley drives the v-belt to enter the vulcanization space formed between the clamping plate and the grooved plate. And after the V-belts enter the corresponding vulcanization spaces, the positioning rods 262 retract to the original positions.

Further, the step 5 further comprises: before the lifting oil cylinder and the pressing oil cylinder act, the second swing arm 242 rotates to enable the groove roller 243 to abut against the supporting seat 25. Specifically, since the clamping plate 343 and the groove plate 344 are pressed by the upper and lower

pressing plates

341 and 342 therebetween at the time of vulcanization, the thickness of the vulcanization space becomes small. And the grooved roller 243 is abutted against the supporting seat 25 by driving, and the grooved roller 243 is positioned by the supporting seat 25, so that when the vulcanization space is shortened, the V-belt still can keep a better parallelism between the clamping plate 343 and the grooved plate 344, and the vulcanization effect is improved.

And further, after the V-belt is vulcanized, the V-belt is required to be removed, and therefore, the V-belt vulcanizing method further comprises the step 6 of reversely moving the lifting oil cylinder and the pressing oil cylinder to separate the clamping plate and the groove plate from each other, driving the V-belt to be separated from the vulcanizing mechanism by the second sliding trolley, driving the second sliding trolley to move to the upper belt mechanism by the first sliding trolley, and removing the V-belt from the groove roller through a transfer roller in the upper belt mechanism.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
