Abstract
Description
Technical Field
[0001] The utility model relates to a bamboo splitting machine, in particular to an automatic alignment and centering clamp for the bamboo splitting machine, belonging to the technical field of bamboo splitting machines. Background Art
[0002] The bamboo splitter uses bamboo tube segments as processing objects, replaces the cutting tool according to the bamboo diameter, and processes the bamboo tube segments into bamboo strips with certain size specifications through the bamboo splitter, so as to prepare materials for the subsequent deep processing of bamboo materials. Its main types include splitting bamboo splitters and sawing bamboo splitters. Among them, the impact type bamboo splitter is more common among the splitting bamboo splitters. When it is working, the bamboo tube segments are manually carried into the workstation, the bamboo diameter is manually visually measured, and the bamboo splitting cutting tool is replaced according to the estimated diameter. Under the action of the propulsion mechanism, the bamboo tube segments enter the cutting tool along the guide rail to complete the splitting.
[0003] In order to ensure that the size of the broken bamboo strips is relatively uniform, the bamboo tube segments need to be in the correct position when they are manually carried into the work station. However, manual adjustment of the bamboo tube position is difficult and the accuracy is difficult to grasp. At the same time, since the propulsion mechanism keeps reciprocating, the adjustment time left for workers is extremely limited and it is easy to cause injuries to workers. Therefore, in response to the above problems, an automatic alignment and centering fixture for a bamboo breaking machine is proposed. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an automatic alignment and centering clamp for a bamboo splitting machine. The clamp for the bamboo splitting machine can be in the form of a caliper with forks upwards, which reduces the difficulty of operation for workers when releasing materials. A bamboo tube only needs to be placed in the fork, and it will slide to the bottom of the caliper structure under the action of gravity to achieve automatic alignment and centering. At this time, the caliper structure will rotate to clamp the bamboo tube to prevent it from sliding during the advancement process and destroying the positioning effect. In addition, when the clamp moves to the end position, an anti-collision signal generating mechanism will emit a warning signal. At this time, the caliper structures are separated from each other and rotate to both sides respectively, avoiding the advancement mechanism and the caliper structure, thereby solving the technical problems in the prior art that it is difficult to operate manually when carrying the bamboo tube into the work station, the risk factor is high, and the advancement mechanism is prone to collision with the set bamboo tube fixing structure during the advancement process.
[0005] In order to solve the above problems, the following technical solutions are provided:
[0006] An automatic alignment and centering fixture for a bamboo splitting machine is designed, comprising a guide rail and a movable alignment fixture slidably arranged on the guide rail, an anti-collision signal generating mechanism is fixedly arranged on the upper part of the rear end surface of the movable alignment fixture, the movable alignment fixture comprises a fixture shell, a rotatable caliper mechanism is arranged in the fixture shell, the clamping part of the rotatable caliper mechanism extends out of the fixture shell, rollers are rotatably installed on both sides of the fixture shell, and a baffle is fixedly arranged at the end of the guide rail.
[0007] In the above structural form, the upper opening size of the rotatable caliper mechanism is relatively large, so workers can insert the bamboo tube more easily. The bamboo tube will slide under the rotatable caliper mechanism under the action of gravity and closely contact the two sides of the rotatable caliper mechanism to achieve automatic alignment and centering. At this time, the rotatable caliper mechanism will rotate to clamp the bamboo tube to prevent it from sliding during the advancement process and destroying the positioning effect. In addition, when the movable alignment clamp moves to the end and contacts the baffle, the bamboo tube has completed most of the advancement and no longer needs to be positioned and fixed. The anti-collision signal generating mechanism will emit a warning signal, and the rotatable caliper mechanisms will separate from each other and rotate outward respectively to avoid hindering the continued forward movement of the advancement mechanism due to the outward extension of part of the structure.
[0008] Furthermore, the rotatable caliper mechanism includes two first articulated seats fixedly arranged on the bottom plate of the clamp housing, and the first articulated seats are rotatably connected to a caliper rod via a first rotating axis. The two caliper rods are symmetrically arranged, and the caliper rods extend out of the clamp housing and are provided with slots on the clamp housing for the movement of the caliper rods.
[0009] The above-mentioned structural form can realize the two clamp rods to rotate around their respective first hinge seats, thereby providing the necessary basic conditions for the opposite movement to clamp the bamboo tube and separate from each other to avoid interfering with the forward movement of the propulsion mechanism.
[0010] Furthermore, adjacent fixed end plates and a driving motor are fixedly arranged on the bottom plate of the clamp housing, the ends of the two first rotating shafts are rotatably connected to the fixed end plates, the end of one of the first rotating shafts is fixedly connected to the output shaft of the driving motor, and a transmission gear is fixedly arranged in the middle of the first rotating shaft, and the two transmission gears are meshed with each other.
[0011] In the above-mentioned structural form, a driving motor can be used to drive a first rotating shaft fixedly connected to its output shaft to rotate, so as to drive the fixedly connected caliper rod to rotate. At the same time, due to the transmission action of the transmission gear, the other first rotating shaft will rotate in the opposite direction, driving the caliper rod fixedly connected to it to rotate in the opposite direction, thereby realizing that the caliper rods can synchronously approach or move away from each other.
[0012] Furthermore, the anti-collision signal generating mechanism includes a contact pressure sensor fixedly arranged on the rear end face of the clamp housing, the contact pressure sensor is electrically connected to the drive motor, guide rods connected to the clamp housing are fixedly arranged on both sides of the contact pressure sensor, sliding sleeves are slidably arranged on the guide rods, and the sliding sleeves are fixedly connected by a connecting cross bar.
[0013] In the above structure, after the connecting cross bar is subjected to a certain external thrust, it will move toward the contact pressure sensor, and finally contact the contact pressure sensor and apply pressure. At this time, the contact pressure sensor generates a signal transmitted to the drive motor, and the drive motor will rotate in the opposite direction to separate the two caliper rods from each other.
[0014] Furthermore, a second hinged seat arranged centrally is fixedly provided on the upper end surface of the connecting cross bar, and a touch plate is rotatably connected to the second hinged seat via a second rotating shaft. Torsion springs are sleeved on the outside of both sides of the second rotating shaft, one end of the torsion spring is fixedly connected to the touch plate, and the other end is fixedly connected to the second hinged seat.
[0015] In the above-mentioned structural form, since the two sides of the touch plate are in direct contact with the propulsion mechanism and the bamboo tube respectively, it will bear the thrust of the propulsion mechanism. When the movable alignment clamp moves to the end and contacts the baffle and cannot move forward further, the thrust of the propulsion mechanism will push the touch plate, and the touch plate will push the connecting cross bar to move toward the contact pressure sensor, and finally contact the contact pressure sensor and apply pressure. At this time, the contact pressure sensor generates a signal to transmit to the drive motor, and the drive motor will rotate in the opposite direction to separate the two caliper rods from each other, so that the propulsion mechanism can continue to move forward without hindrance. In particular, when the connecting cross bar contacts the contact pressure sensor and cannot move further, the touch plate will overcome the resistance of the torsion spring and rotate to a horizontal state under the action of the thrust, without hindering the forward movement of the propulsion mechanism.
[0016] Furthermore, the guide rod outer sleeve is provided with a return spring, one end of the return spring is in contact with the fixture housing, and the other end is in contact with the sliding sleeve, and the end of the guide rod is fixedly connected with an anti-dropping end cap.
[0017] The above structural form can enable the connecting cross bar to return to its original position after the external force is removed, so as to facilitate the next use.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] In the utility model, the upward forked caliper can be used to reduce the difficulty of operation for workers when releasing materials. The bamboo tube only needs to be placed in the fork, and it will slide to the bottom of the caliper structure under the action of gravity to achieve automatic alignment and centering. At this time, the caliper structure will rotate to clamp the bamboo tube to prevent it from sliding during the advancement process and destroying the positioning effect. In addition, when the clamp moves to the end position, the anti-collision signal generating mechanism will emit a warning signal. At this time, the caliper structures are separated from each other and rotate to both sides respectively to avoid the advancement mechanism and the caliper structure.

DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0027] like Figure 1 - Figure 2 As shown, the present embodiment provides an automatic alignment and centering fixture for a bamboo splitting machine, comprising a guide rail 1 and a movable alignment fixture 2 slidably arranged on the guide rail 1, the movable alignment fixture 2 comprising a fixture housing 21, a rotatable caliper mechanism 22 being arranged in the fixture housing 21, a clamping portion of the rotatable caliper mechanism 22 extending out of the fixture housing 21, and rollers 23 rotatably connected are installed on both sides of the fixture housing 21. In the above-mentioned structural form, the upper opening size of the rotatable caliper mechanism 22 is relatively large, and workers can insert the bamboo tube more easily when inserting it. The bamboo tube will slide under the rotatable caliper mechanism 22 under the action of gravity and be in close contact with both sides of the rotatable caliper mechanism 22 to realize automatic alignment and centering. At this time, the rotatable caliper mechanism 22 will rotate to clamp the bamboo tube to prevent it from sliding during the advancement process and destroying the positioning effect.
[0028] like Figure 1As shown, an anti-collision signal generating mechanism 3 is fixedly provided on the upper part of the rear end surface of the movable alignment clamp 2, and a baffle 4 is fixedly provided at the end of the guide rail 1. When the movable alignment clamp 2 moves to the end of the guide rail 1 and contacts the baffle 4 under the pushing action of the propulsion mechanism, the bamboo tube has completed most of the propulsion and no longer needs to be positioned and fixed. The anti-collision signal generating mechanism 3 will emit a warning signal, and the rotatable caliper mechanisms 22 will separate from each other and rotate outward respectively to avoid hindering the continued forward movement of the propulsion mechanism due to the outward extension of some structures.
[0029] like Figure 3 As shown, the rotatable caliper mechanism 22 includes two first articulated seats 221 fixedly arranged on the bottom plate of the clamp housing 21, and the first articulated seats 221 are rotatably connected with a caliper rod 222 through a first rotating shaft 223. The two caliper rods 222 are symmetrically arranged, and the caliper rods 222 extend out of the clamp housing 21 and are provided with slots for the movement of the caliper rods 222. The above-mentioned structural form can realize the rotation of the two caliper rods 222 around their respective first articulated seats 221, thereby providing the necessary basic conditions for the opposite movement to clamp the bamboo tube and separate from each other to avoid interfering with the forward movement of the propulsion mechanism.
[0030] like Figure 3 As shown, adjacent fixed end plates 225 and driving motors 226 are fixedly arranged on the bottom plate of the clamp housing 21, and the ends of the two first rotating shafts 223 are rotatably connected to the fixed end plates 225, and the end of one of the first rotating shafts 223 is fixedly connected to the output shaft of the driving motor 226. A transmission gear 224 is fixedly arranged in the middle of the first rotating shafts 223, and the two transmission gears 224 are meshed with each other, so that the driving motor 226 can drive one of the first rotating shafts 223 fixedly connected to its output shaft to rotate, so as to drive the fixedly connected caliper rod 222 to rotate. At the same time, due to the transmission action of the transmission gear 224, the other first rotating shaft 223 will rotate in the opposite direction, driving the caliper rod 222 fixedly connected to it to rotate in the opposite direction, thereby realizing that the caliper rods 222 can synchronously approach or move away from each other.
[0031] like Figure 4 As shown, the anti-collision signal generating mechanism 3 includes a contact pressure sensor 31 fixedly arranged on the rear end face of the clamp housing 21, the contact pressure sensor 31 is electrically connected to the drive motor 226, and guide rods 32 connected to the clamp housing 21 are fixedly arranged on both sides of the contact pressure sensor 31, and sliding sleeves 33 are slidably arranged on the guide rods 32, and the sliding sleeves 33 are fixedly connected by connecting cross bars 34. In the above structural form, after the connecting cross bar 34 is subjected to a certain external thrust, it will move toward the contact pressure sensor 31, and finally contact the contact pressure sensor 31 and apply pressure, at this time, the contact pressure sensor 31 generates a signal transmitted to the drive motor 226, and the drive motor 226 will rotate in the opposite direction to separate the two caliper rods 222 from each other.
[0032] like Figure 4 As shown, a centrally arranged second hinge seat 35 is fixedly provided on the upper end surface of the connecting cross bar 34, and a touch plate 37 is rotatably connected to the second hinge seat 35 via a second rotating shaft 36. Torsion springs 38 are sleeved on the outside of both sides of the second rotating shaft 36, one end of the torsion spring 38 is fixedly connected to the touch plate 37, and the other end is fixedly connected to the second hinge seat 35. In the above structural form, since the touch plate 37 extends upward for a certain distance and is in direct contact with the propulsion mechanism and the bamboo tube on both sides, it will bear the thrust of the propulsion mechanism. When the movable alignment clamp 2 moves to the end and contacts the baffle 4 and cannot continue to move forward, the thrust of the propulsion mechanism will push the touch plate 37, and the touch plate 37 will push the connecting cross bar 34 to move toward the contact pressure sensor 31, and finally contact the contact pressure sensor 31 and apply pressure. At this time, the contact pressure sensor 31 generates a signal and transmits it to the drive motor 226, and the drive motor 226 will rotate in the opposite direction to separate the two caliper rods 222 from each other, so that the propulsion mechanism can continue to move forward without hindrance.
[0033] In particular, when the connecting crossbar 34 contacts the contact pressure sensor 31 and cannot move further, the touch plate 37 will overcome the resistance of the torsion spring 38 and rotate to a horizontal state under the action of the thrust, without hindering the forward movement of the propulsion mechanism.
[0034] like Figure 4 As shown, a return spring 39 is provided on the outer sleeve of the guide rod 32, one end of the return spring 39 contacts the clamp housing 21, and the other end contacts the sliding sleeve 33. The end of the guide rod 32 is fixedly connected with an anti-drop end cap 321. The above-mentioned structural form can enable the connecting cross bar 34 to return to its original position after the external force is removed, so as to facilitate the next use.
[0035] The use principle and use process of the utility model are as follows: the driving motor 226 inside the rotatable caliper mechanism 22 can drive a first rotating shaft 223 fixedly connected to its output shaft to rotate, so as to drive the fixedly connected caliper rod 222 to rotate. At the same time, due to the transmission effect of the transmission gear 224, the other first rotating shaft 223 will rotate in the opposite direction, driving the caliper rod 222 fixedly connected to it to rotate in the opposite direction, thereby realizing that the caliper rods 222 can be synchronously approached or moved away from each other, and then when the bamboo tube is placed, the caliper rods 222 move away from each other to expand the opening between the two, so that the worker can insert the bamboo tube more easily. The bamboo tube will slide down under the action of gravity to the right below the clamping space enclosed by the two caliper rods 222, and closely contact the inner side of the caliper rod 222 to realize automatic alignment and centering. At this time, the driving motor 226 can drive the rotating caliper rods 222 to rotate close to each other, so as to clamp the bamboo tube and prevent it from sliding during the advancement process and destroying the positioning effect.
[0036] In addition, the touch plate 37 in the anti-collision signal generating mechanism 3 extends upward for a certain distance and is in direct contact with the propulsion mechanism and the bamboo tube on both sides. It will bear the thrust of the propulsion mechanism. When the movable alignment clamp 2 moves to the end and contacts the baffle 4 and cannot continue to move forward, the thrust of the propulsion mechanism will push the touch plate 37, and the touch plate 37 will push the connecting cross bar 34 to move toward the contact pressure sensor 31, and finally contact the contact pressure sensor 31 and apply pressure. At this time, the contact pressure sensor 31 generates a signal to the drive motor 226, and the drive motor 226 will rotate in the opposite direction to separate the two caliper rods 222 from each other, so that the propulsion mechanism can continue to move forward without hindrance.
