Description

Technical Field

[0001] The invention belongs to the technical field of mechanical transmission equipment, and in particular relates to a direction-changing reciprocating multi-output mechanism. Background Art

[0002] Most of the existing direction-changing mechanisms rely on circuits or gas circuits for control, which makes the structure of the entire direction-changing mechanism very complicated and inconvenient for subsequent maintenance. In addition, the direction-changing mechanism is prone to wear and tear due to its frequent direction-changing actions during use, which reduces its service life after long-term use. For example, the reciprocating cutting drive device (CN1031158172A) in the prior art can convert rotary motion into reciprocating motion and then drive the cutting device to reciprocate. The reciprocating cutting drive device uses a belt for transmission, which results in load limitation during transmission. At the same time, the use of an eccentric wheel will limit the rotation speed, resulting in poor practicality of the reciprocating cutting drive device.

[0003] In addition, the existing direction-changing mechanism has a single power input that can only correspond to one output direction, so that the existing direction-changing mechanism can only perform direction-changing movement in a single direction, resulting in poor practicality and inability to be flexibly used in various automated production lines. If multiple output directions are achieved through the existing direction-changing mechanism, a lot of corresponding power inputs will be required, which will cause the entire direction-changing mechanism to have a large structure and high production costs, and will not be conducive to its later maintenance and parts replacement. Moreover, the existing direction-changing mechanism has a fast conveying speed when conveying articles, which is easy to produce rigid impact on the articles, causing damage to the articles during production or transportation. Furthermore, the existing direction-changing mechanism can not only only perform direction-changing movement in a single direction, but also cannot adjust the direction of its change of direction.

[0018] The technical solution provided by the present invention has the following beneficial effects:

[0019] (1) The reversible reciprocating multi-output mechanism of the present invention is provided with a driving member, a gear three, a gear two, a gear one and a crank rocker device, and the two ends of the crank rocker device are connected to the gear three and the gear one respectively. The driving member can drive the gear two and the gear one to rotate respectively through the gear three, that is, the gear two and the gear one can be used as the two output directions of the reversible reciprocating multi-output mechanism, so that the input of a driving source can correspond to two output directions, thereby improving its practicality. In combination with the crank rocker device, the driving member can not only drive the gear assembly one and the gear assembly two to move respectively, but also enable the gear assembly two and the gear assembly one to reciprocate respectively, so that the reversible reciprocating multi-output mechanism of the present invention can be applied to more usage scenarios, thereby improving its practicality. In addition, the reversible reciprocating multi-output mechanism of the present invention also utilizes the characteristics of the crank rocker device, so that the time required for the reversible reciprocating multi-output mechanism in the working stage and the non-working stage is different, and the time required for the non-working stage is short, thereby achieving an increase in the time allocated to the working stage within the same time, thereby improving the working efficiency of the entire reversible reciprocating multi-output mechanism.

[0020] (2) The direction-changing reciprocating multi-output mechanism of the present invention cooperates with the limit block 2, the connecting block, the spring 2 of the linear quick-spring assembly and the limit block 1 in the gear assembly 2 to realize that when the rack 2 reciprocates, the linear quick-spring assembly will also move accordingly, so that the linear quick-spring assembly can be used as a counting module to count the working cycle of the direction-changing reciprocating multi-output mechanism, so that the direction-changing reciprocating multi-output mechanism of the present invention can not only realize multi-directional reciprocating output, but also count the number of times of this movement process.

[0021] (3) The variable direction reciprocating multi-output mechanism of the present invention utilizes the characteristics of the crank rocker device to slow down the transportation speed of the items to be processed during the processing stage, thereby achieving stable transportation and processing of the items and avoiding collisions and damage during the processing; and the linear quick-release mechanism can quickly push the processed items to the next stage, thereby increasing the speed of the processed items, thereby achieving both slow and stable processing of the items and ensuring work efficiency between units.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0033] In the description of the present invention, it should be noted that for directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions and positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific protection scope of the present invention. The terms "first", "second", etc. in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. The terms "including" and "having" in the specification and claims of the present invention and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] This embodiment provides a reversible reciprocating multi-output mechanism, such as Figures 1 to 3As shown, it includes: gear assembly 1, gear assembly 2, power assembly and linear fast-bounce assembly 4. One end of the power assembly is connected to gear assembly 1, and the other end of the power assembly is connected to gear assembly 2. The power assembly is used to provide power input for the entire direction-changing multi-output mechanism. The gear assembly 1 includes gear 11 and rack 12, and the gear 11 and rack 12 are meshed with each other. The gear assembly 2 includes gear 21 and rack 22, and the gear 21 and rack 22 are meshed with each other. The power assembly includes a driving member 31, gear 3 32 and a crank rocker device 33. The gear 3 32 is arranged between the gear 2 21 and the gear 1 11, and one end of the gear 3 32 can be meshed with the gear 1 11, and the other end of the gear 3 32 can be meshed with the gear 2 21. Please refer to Figure 1 and Figure 4 , the driving member 31 and the crank rocker device 33 are arranged on both sides of the gear 3 32. Being arranged on both sides of the gear 3 32, the driving member 31 can drive the gear 3 32 to rotate, and the shaft at the connection of the driving member 31 does not interfere with the transmission of the crank rocker device 33. The output shaft of the driving member 31 is connected to the rotating shaft of the gear 3 32, and the gear 3 32 is driven to rotate by the rotation of the driving member 31. One end of the crank rocker device 33 is fixed to the output shaft of the driving member 31, and the other end of the crank rocker device 33 is connected to the gear 1 11. The crank rocker device 33 is driven to move by the motor, and the reciprocating motion of the rack 1 12 and the rack 2 22 is realized under the mutual cooperation of the crank rocker device 33, the gear 1 11, the gear 2 21 and the gear 3 32. The two output directions of the gear 1 11 and the gear 2 21 are realized through the power input of the gear 3 32, simplifying the structure of the entire reciprocating multi-output mechanism.

[0035] In this embodiment, the drive member 31 and the crank rocker device 33 can provide power input to the gear assembly 1 and the gear assembly 2 at the same time, so that the gear assembly 1 can reciprocate. During the reciprocating motion of the gear assembly 1, due to the provision of the crank rocker device 33, the time consumed by the gear assembly 1 in the reciprocating process is different. In this embodiment, the process of the rack 12 moving to the left is regarded as the working stroke, and the process of the rack 12 moving to the right is regarded as the non-working stroke (i.e., the idle return stroke). Due to the effect of the crank rocker device 33, the time for the rack 12 to move to the left is greater than the time for the rack to move to the right. Through this setting, the entire direction-changing reciprocating multi-output mechanism can reasonably utilize time when used in the production line, thereby improving the working efficiency of the entire direction-changing reciprocating multi-output mechanism. In addition, by providing the drive member 31 and the crank rocker device 33, the gear assembly 2 can also meet the reciprocating motion with a quick return characteristic. This quick return feature can make the parallel speed of the working stroke small, so that the working stroke is stable and the speed of the non-working stroke (i.e., the idle return stroke) is accelerated to shorten the non-working time and achieve the purpose of improving work efficiency.

[0036] Please refer to Figure 1 and Figure 2 , the linear quick-release assembly 4 includes a guide rail 41, a sliding member, a spring 1 43, a mounting block 44 and a limit block 2 45. The guide rail 41 is arranged in parallel with the rack 2 22. The mounting block 44 is installed on the upper surface of the guide rail 41, and the limit block 2 45 is installed on the side of the guide rail 41 close to the rack 2 22. In this embodiment, the movement direction of the rack 2 22 is the horizontal direction, and the limit block 1 221 is located above the limit block 2 45 in the vertical direction. Through this arrangement, when the rack 2 22 drives the limit block 1 221 to move in the horizontal direction, the limit block 1 221 and the limit block 2 45 will not contact each other, so that the limit block 2 45 will not interfere with the movement of the limit block 1 221. One end of the spring 1 43 is fixedly connected to the mounting block 44, and the other end of the spring 1 43 is fixedly connected to the sliding member. Please refer to Figures 2 to 4 The sliding member includes a slider 421 and a connecting block 422. The slider 421 is slidably mounted on the guide rail 41 and the sliding direction of the slider 421 is consistent with the movement direction of the rack 22. The connecting block 422 is telescopically mounted on the slider 421. The connecting block 422 and the limit block 2 45 are located on the same side of the guide rail 41. Please refer to Figure 5 The distance between the lower end surface of the connecting block 422 and the lower end surface of the guide rail 41 is smaller than the distance between the upper end surface of the limiting block 45 and the lower end surface of the guide rail 41.

[0037] In this embodiment, the slider 421 is provided with a mounting groove along the width direction of the guide rail 41, a second spring is installed in the mounting groove, and a plug rod is provided on one end of the connecting block 422 inserted into the mounting groove, and the plug rod is inserted into the mounting groove and fixedly connected with the second spring. When the connecting block 422 is subjected to external force, the connecting block 422 will drive the plug rod to move into the mounting groove, and the second spring will be compressed. When the external force disappears, under the elastic force of the second spring, the connecting block 422 is pushed by the plug rod to move away from the mounting groove. Through the above operation, the connecting block 422 is telescopically installed on the slider 421.

[0038] Please refer to Figure 1 and Figure 2 The connecting block 422 is a rectangular parallelepiped and the side close to the spring 1 43 is an arc-shaped surface; the limit block 1 221 is a circular limit block, and the limit block 1 221 is rotatably installed on the rack 2 22; when the limit block 1 221 moves to the right along with the rack 2 22 and abuts against the arc-shaped surface, the limit block 1 221 moves to the right while pushing the connecting block 422 toward the installation groove through the arc-shaped surface; when the limit block 1 221 moves to the left along with the rack 2 22 and abuts against the connecting block 422, the limit block will push the connecting block 422 to move to the left until the connecting block 422 abuts against the limit block 2 45, and at this time, the spring 1 43 is in a compressed state. Under the action of the limit block 2 45, the connecting block 422 will shrink into the installation groove, and the limit block 1 221 will move from the right side of the connecting block 422 to the left side of the connecting block 422. At this time, the limit block 1 221 has no leftward force on the connecting block 422. Under the elastic force of the spring 1 43, the connecting block 422 will move to the right to its original position.

[0039] In this embodiment, please refer to Figure 2, the connecting block 422 is a rectangular parallelepiped and the side close to the spring 1 43 is an arc-shaped surface. The limit block 1 221 is a circular limit block, and the limit block 2 45 is also a circular limit block. When the limit block 1 221 moves from the left side to the right side of the connecting block 422, the limit block 1 221 will directly push the connecting block 422 in the direction of the installation slot, so that the limit block 1 221 can quickly move from the left side to the right side of the connecting block 422. When the limit block 1 221 moves from the right side to the left side of the connecting block 422, the right side of the connecting block 422 is a right-angled surface, so the limit block 1 221 will drive the connecting block 422 to move to the left together, and at this time, the spring 1 43 will be compressed until the connecting block 422 abuts against the limit block 2 45, and the limit block 2 45 is also a circular limit block. Under the action of limit block 2 45, the connecting block 422 will shrink into the installation groove, so that the limit block 1 221 will move from the right side of the connecting block 422 to the left side, that is, the limit block 1 221 has no force on the connecting block 422, so under the elastic force of spring 1 43, the connecting block 422 will move to the right to its original position.

[0040] In this embodiment, a steering gear may be provided between the gear 2 21 and the gear 3 32. The steering gear may be a universal coupling or a bevel gear, and the direction of the gear assembly 2, i.e., the direction of the rack 2 22, can be changed by providing the universal coupling or the bevel gear, thereby achieving the purpose of steering.

[0041] It can be understood that the linear quick-spring assembly in this embodiment can be used as a counting module. When the linear quick-spring assembly is used as a counting module, the movement of rack 2 from left to right and then from right to left is counted as a working cycle, and in this working cycle, spring 1 pops out once, so in the actual operation process, the number of times the spring 1 43 pops out can be used to calculate the number of times the reversing reciprocating multi-output mechanism works repeatedly. The specific counting operation of the linear quick-spring assembly as a counting module can refer to the following description of the application of the reversing reciprocating multi-output mechanism of the present invention to the cutting scene.

[0042] It is understandable that when the linear quick-spring assembly is used as a counting module, a sensor can be installed on the guide rail, and the sensor is installed within the sliding range of the slider. The sensor is used to count once when the spring 1 43 pushes the slider 421 to move rightward once, thereby achieving the purpose of counting the working cycle of the variable direction reciprocating multi-output mechanism, making the entire variable direction reciprocating multi-output mechanism more intelligent and convenient.

[0043] It is understandable that the linear quick-elastic component in this embodiment can also be used as a steering pusher in the reversing reciprocating multi-output mechanism. When the linear quick-elastic component is used as a steering pusher, it also includes a push plate, which is fixedly connected to the side of the slider 421 opposite to the spring 1 43, and the push plate is used to push the items conveyed by the rack 12 to the next process when the spring 1 43 pushes the slider 421 to its original position. At this time, the linear quick-elastic component can speed up the processed items, so that it can not only meet the slow and stable processing of the items within a unit time, but also can quickly push the processed items to the next stage after processing, thereby reducing the time consumed by the entire reversing reciprocating multi-output mechanism in the non-working stage and improving work efficiency. The specific use of the linear quick-elastic component as a steering pusher can refer to the following operation of applying the reversing reciprocating multi-output mechanism of the present invention to the material conveying scenario.

[0044] It can be understood that in this embodiment, by setting the limit block 1 221, when the limit block 1 221 moves from the right end to the left end along with the rack 22, the limit block 1 221 will first compress the spring 1 43 of the linear quick-elastic assembly, and then under the action of the limit block 2 45, the limit block 1 221 moves from the right side to the left side of the connecting block 422. At this time, the limit block 1 221 has no force on the spring 1 43, so that the elastic force of the spring 1 43 can drive the slider 421 to move to the right. Through this design, the linear quick-elastic assembly itself does not need to set up an additional component to compress the spring 1 43 to achieve the operation of ejecting the slider 421 and the connecting block 422 through the spring 1 43, which can simplify the structure of the linear quick-elastic assembly. At the same time, by setting the limit block 1 221, the limit block 2 45 and the connecting block 422, the consistency of the linear quick-spring assembly and the gear 2 21 during operation can be maintained, so that the linear quick-spring assembly can be used as a counting module in some scenarios, and in other scenarios, the elastic force accumulated by the spring 1 43 can be used to provide thrust for the material that needs to change the conveying direction, making the entire change-of-direction reciprocating multi-output mechanism more practical.

[0045] In this embodiment, the crank rocker device 33 is selected to simultaneously meet the requirements of full rotation of the crank 331 and reciprocating motion of the rocker 333.

[0046] Understandably, please refer to Figure 3, the crank rocker device 33 includes a crank 331, a connecting rod 332 and a rocker 333. One end of the crank 331 is fixed to the output shaft of the driving member 31, the other end of the crank 331 is hinged to one end of the connecting rod 332, the other end of the connecting rod 332 is hinged to one end of the rocker 333, and the other end of the rocker 333 is fixed to the rotating shaft of the gear one 11. The crank 331 and the driving member 31 are respectively arranged at the two ends of the gear. In the actual installation process, the output shaft of the driving member 31 passes through the gear three 32 and is connected to the crank 331, so that the driving member 31 drives the gear three 32 and the crank 331 to rotate respectively. On the side of the gear 3 32, the crank 331 is provided, and the distance between the output shaft of the driving member 31 and the gear 3 32 is smaller than the distance between the connecting rod 332 and the gear 3 32. Through the above design, when the connecting rod 332 rotates with the crank 331, the output shaft of the driving member 31 will not interfere with the movement of the connecting rod 332. In this embodiment, the crank 331 is connected to the output shaft of the driving member 31, so as to provide power input for the operation of the entire crank rocker device 33. The rocker 333 is fixedly connected to the gear 1 11, so that the reciprocating swing of the rocker 333 can be changed into the direction-changing rotation of the gear 1 11. The connection between the connecting rod 332 and the crank 331 and between the connecting rod 332 and the rocker 333 can be connected by a key pin. The key pin connection makes it easy to replace these three components separately, making the maintenance of the crank rocker device 33 more convenient.

[0047] Assumptions Figure 6 This is the initial state of the reversing multi-output mechanism. At this time, the driving member 31 does not rotate and the rocker 333 is at the extreme left end point. The position of the rocker 333 is set as the extreme position 1 51. At this position, the crank 331 and the connecting rod 332 overlap. When the driving member 31 starts to rotate clockwise and drives the gear 3 32 and the crank rocker device 33 to rotate, until the rocker 333 rotates to the extreme right end point, please refer to Figure 7 , the position of the rocker 333 at this time is set to be the extreme position 2 52, at which the distance between the end point where the crank 331 is connected to the driving member 31 and the end point where the connecting rod 332 is connected to the rocker 333 is the longest.

[0048] In this embodiment, the movement range of the rocker 333 is always between the extreme position 1 51 and the extreme position 2 52 .

[0049] In this embodiment, the process of moving the rocker 333 from the extreme position 1 51 to the extreme position 2 52 is called an idle return stroke; the process of moving the rocker 333 from the extreme position 2 52 to the extreme position 1 51 is called a working stroke. The following describes the specific details of the two states of the reciprocating multi-output mechanism in this embodiment in the idle return stroke and the working stroke.

[0050] (I) Idle return stroke: In the idle return stroke, the driving member 31 drives the gear 3 32 to rotate clockwise, and the rocker 333 moves from the extreme position 1 51 to the extreme position 2 52. In this process, the gear 3 32 drives the gear 1 11 and the gear 2 21 to rotate counterclockwise, and the gear 1 11 drives the rack 1 12 to move rightward, and the gear 2 21 drives the rack 2 22 to move rightward as well. Figure 6 and Figure 7 It can be seen that when the rocker 333 moves from the extreme position 1 51 to the extreme position 2 52, the rack 1 12 and the rack 2 22 will also move from the leftmost end to the rightmost end. For the rack 1 12, as the gear 3 32 rotates clockwise, the gear 1 11 will rotate counterclockwise, and the gear 1 11 will drive the rack 1 12 to move rightward until the rocker 333 moves to the extreme position 2 52. For the rack 2 22, as the gear 3 32 rotates clockwise, the gear 2 21 will rotate counterclockwise, and the gear 2 21 will drive the rack 2 22 to move rightward. Under the movement of the rack 2 22, the limit block 1 221 will also move rightward. In the process of the limit block 1 221 moving to the right, when the limit block 1 221 moves to the right along with the gear 2 21 to abut against the left side of the connecting block 422, as the gear 2 21 continues to move to the right, the limit block 1 221 will push the connecting block 422 to shrink into the installation slot, and the spring 2 will be compressed. Then the limit block 1 221 will move from the left side of the connecting block 422 to the right side of the connecting block 422 along the side of the connecting block 422. When the limit block 1 221 moves to the right side of the connecting block 422, the connecting block 422 returns to its original position under the elastic force of the spring 2, and the rack 2 22 will continue to move to the right until the rocker 333 rotates to the limit position 2 52.

[0051] (II) Working stroke: When the driving member 31 drives the gear 3 32 to rotate counterclockwise, the rocker 333 will move from the extreme position 2 52 to the extreme position 1 51. In this process, as the gear 3 32 rotates counterclockwise, the gear 3 32 will drive the gear 2 21 and the gear 1 11 to rotate clockwise. The gear 1 11 will drive the rack 1 12 to move from the rightmost end to the leftmost end until the rocker 333 moves to the extreme position 1 51. The gear 2 21 will drive the rack 2 22 to move from the rightmost end to the leftmost end until the rocker 333 moves to the extreme position 1 51. With the movement of the rack 2 22, the limit block 1 221 will also move leftward with the rack 2 22. In the process of the limit block 1 221 moving from the rightmost end to the leftmost end, the limit block 1 221 will first abut against the right side of the connection block 422. Since the connection block 422 is a rectangular parallelepiped and the side close to the spring 1 43 is an arc surface, the limit block 1 221 will drive the connection block 422 to move to the left together, and the spring 1 43 will be compressed until the connection block 422 abuts against the limit block 2 45. Under the action of the limit block 2 45, the connection block 422 will shrink toward the installation slot, and the limit block 1 221 can move from the left side of the connection block 422 to the right side. When the limit block 1 221 moves to the right side of the connection block 422, the limit block 1 221 exerts a force on the connection block 422. At this time, under the elastic force of the spring 1 43, the connection block 422 will move to the right to its original position. The limiting block 1 221 can continue to move leftward along with the rack 2 22 until the rocker 333 rotates to the limit position 1 51 .

[0052] In this embodiment, please refer to Figure 8 , Figure 8 B1 is when the rocker 333 rotates to the limit position 1 51, and B2 is when the rocker 333 rotates to the limit position 2 52. The swing angle of the rocker 333 is α, and its value can be 88°. The extreme position angle θ of the crank 331 can be 14°. The length of the crank 331 is a, the length of the connecting rod 332 is b, and the length of the rocker 333 is c. The relationship between a, b and c satisfies a:b:c=17:90:30.

[0053] In this embodiment, the gear 1 11, the gear 2 21 and the gear 3 32 can be spur gears. When the three gears are spur gears and the two sides of the gear 3 32 are directly meshed with the gear 1 11 and the gear 2 21 respectively, the gear assembly 1 and the gear assembly 2 are both on the same plane, and the reversing reciprocating multi-output mechanism can be used to transport or process materials on the same plane.

[0054] The driving member 31 can be a motor. The motor drives the gear 3 32 to provide a power source for the entire direction-changing reciprocating multi-output mechanism, so that the direction-changing reciprocating multi-output mechanism of the present invention does not need to rely on complex circuits or gas circuits, and simplifies the structure of the direction-changing reciprocating multi-output mechanism.

[0055] The module of the gear 1 11 can be 2, and the number of teeth can be 30. The module of the gear 2 21 can be 2, and the number of teeth can be 65. The module of the gear 3 32 can be 2, and the number of teeth can be 17. By selecting the gears under the above size, the structure of the entire reciprocating multi-output mechanism is compact and occupies a small space, so that the reciprocating multi-output mechanism of the present embodiment can be applied to scenes with smaller spaces. In the present embodiment, the gear transmission method is selected, so that the entire reciprocating multi-output mechanism of the reciprocating direction has the advantages of high precision, good reliability, large load-bearing capacity, wide application range, good wear resistance, etc. In the present embodiment, the gear 1 11, the gear 2 21 and the gear 3 32 can directly select standard gears, so that the production cost can be reduced while the transmission ratio in the entire transmission process can be easily controlled, so as to achieve precise transmission. In addition, when selecting the gears, gears made of high-strength steel or alloy materials can be preferably selected to ensure the durability of each gear in the entire gear transmission process and extend the service life of the entire reciprocating multi-output mechanism of the reciprocating direction.

[0056] In actual operation, the sizes of the gear 1 11, the gear 2 21, the gear 3 32, the crank 331, the connecting rod 332 and the rocker 333 can be designed according to the actual application scenarios of the variable direction reciprocating multi-output mechanism, thereby improving the flexibility and practicality of the entire variable direction reciprocating multi-output mechanism.

[0057] In addition, the inventor of the present application also compared the variable direction reciprocating multi-output mechanism in the present embodiment with several existing mechanisms, and the comparison results are as follows: (1) By comparing the variable direction reciprocating multi-output mechanism in the present embodiment with the reciprocating cutting drive device in the prior art (CN1031158172A), it can be seen that the reciprocating cutting drive device in the prior art uses a belt for transmission, which results in load limitation during the transmission process, and the use of an eccentric wheel limits the speed of the reciprocating cutting drive device. The variable direction reciprocating multi-output mechanism in the present embodiment has a wide input speed range and can operate at high speed; at the same time, compared with belt transmission, the gear train design of the mechanism has less wear and a higher safety factor, which makes the entire variable direction reciprocating multi-output mechanism have a long service life and extends its service life. (2) Comparing the direction-changing reciprocating multi-output mechanism in this embodiment with a tamping machine with a double crank rocker mechanism in the prior art (CN104088270B), it can be seen that the movement of the tamping machine with a double crank rocker mechanism in the prior art is driven only by the connecting rod driving the tamping block, and the connecting rod in the double crank rocker mechanism cannot achieve high-speed movement while carrying a heavy object, but the weight of the tamping block in the tamping machine is relatively heavy, so in order to achieve tamping, the tamping machine can only move at a low speed. Therefore, there is a contradiction between the movement speed and the weight of the driven parts of the tamping machine using the double crank rocker mechanism in the prior art. This greatly limits the working efficiency of the double crank rocker mechanism. The direction-changing reciprocating multi-output mechanism of this embodiment is provided with a linear fast-elastic mechanism, so that when the object to be processed is large and the speed is slow, the speed of the processed object can be increased through the linear fast-elastic mechanism, so that the contradiction between speed and weight is eased, thereby improving work efficiency. (3) Comparing the direction-changing reciprocating multi-output mechanism in this embodiment with a crank rocker mechanism (CN107165997A) in the prior art with a rocker swing angle capable of bidirectional buffering, it can be seen that the spring in this mechanism can only reduce the damage caused by rigid impact to the transported object. In this embodiment, by setting a linear fast-bounce mechanism, it is not only possible to reduce the damage caused by rigid impact to the transported object, but also to use the spring to achieve the effect of energy conversion, thereby achieving the purpose of speed change of the processed object and realizing the effective utilization of this part of the energy of the compression spring. In summary, the direction-changing reciprocating multi-output mechanism in this embodiment is a great improvement over the prior art.

[0058] It can be understood that the reversible reciprocating multi-output mechanism in this embodiment has adjustable size, free movement space, and can be flexibly installed on various machines and cooperate with other transmission mechanisms to achieve more freedom of operation. This makes the reversible reciprocating multi-output mechanism applicable to a variety of scenarios, such as material cutting, material transportation, textile machinery, printing machinery, packaging machinery, machine tools, and automobiles.

[0059] The actual operation of the variable direction reciprocating multi-output mechanism in the present invention applied to the two scenarios of material cutting and material transportation will be described below.

[0060] 1. Apply it to material cutting scenarios

[0061] In the material cutting scenario, the gear assembly 2 in the reversible reciprocating multi-output mechanism of the present invention can be used as a feeding mechanism, the gear assembly 1 can be used as a cutting mechanism, and the linear quick-spring assembly 4 can be used as a counting module. In this embodiment, the gear 1 11, the gear 2 21 and the gear 3 32 are all spur gears, and the gear 2 21 and the gear 1 11 are arranged on both sides of the gear 3 32, one end of the gear 3 32 is meshed with the gear 2 21, and the other end of the gear 3 32 is meshed with the gear 1 11.

[0062] When the gear assembly 2 is used as a feeding assembly, the length of the rack 2 22 should be greater than or equal to the distance between the center of the gear 2 21 and the center of the gear 3 32, so that the rack 2 22 can achieve the purpose of effective feeding.

[0063] In this scenario, a placement plate can be connected to the rack 22, and the placement plate can be used to place the material to be cut. The cutting tool is installed on the rack 12, and a cutting platform is provided below the rack 12. The rack 12 moves from right to left to realize the cutting operation of the material to be cut on the cutting platform. Therefore, in this scenario, the first gear assembly is the working area.

[0064] The specific usage is as follows:

[0065] When the initial state is set, the rocker 333 is located at the limit position 1 51. At this time, the rack 1 12 and the rack 2 22 are both moved to the leftmost end. In this scenario, the left side of the rack 2 22 is the feeding end. When the rack 2 22 moves to the leftmost end, the metal plate to be cut can be placed on the placement plate, and then the motor is started to rotate clockwise, the motor will drive the gear 3 32 to rotate clockwise, and the gear 3 32 will drive the gear 2 21 and the gear 1 11 to rotate counterclockwise respectively. The gear 2 21 will drive the rack 2 22 to move from left to right until the rack 2 22 delivers the material to be cut to the cutting platform, and at this time, the rocker 333 also moves from the limit position 1 51 to the limit position 2 52. When the rocker 333 reaches the limit position 2 52, the motor rotates counterclockwise, the motor will drive the gear 3 32 to rotate counterclockwise, and the gear 3 32 will drive the gear 2 21 and the gear 1 11 to rotate clockwise respectively. Gear 11 drives rack 12 at the rightmost end to perform cutting operation on the material to be cut on the cutting platform from right to left. When the rocker 333 moves from the extreme position 252 to the extreme position 151, the rack 12 moves from the leftmost end to the rightmost end, so that the tool on the rack 12 completes the cutting operation on the material to be cut on the cutting platform, and the rack 222 also moves from the rightmost end to the leftmost end to realize the loading operation on the next material to be cut. During the entire cycle of cutting the material to be cut, the spring 143 of the linear quick-spring assembly also completes the operation of ejecting the sliding member once under the action of the rack 22 and the limit block 1221. Therefore, in this embodiment, as long as the rack 12 drives the tool to complete cutting the material to be cut once, the spring 143 of the linear quick-spring assembly will pop out once. Therefore, in this scenario, the linear quick-spring assembly can be used as a counting module, and the number of materials to be cut that have been cut is calculated by the number of times the spring 143 pops out.

[0066] In the cutting working cycle, because in this embodiment, the idle return stroke is from the limit position 1 51 to the limit position 2 52, and the working stroke is from the limit position 2 52 to the limit position 1 51. According to the characteristics of the crank rocker device 33, the time of the idle return stroke is shorter than the time of the working stroke, and the speed of the working stroke is slower than the speed of the idle return stroke. Therefore, the reversing reciprocating multi-output mechanism of this embodiment is selected, which can shorten the feeding time of the gear assembly 2 and increase the cutting time of the gear assembly 1, and when cutting, the movement speed of the rack 1 12 is slow, so that the rack 1 12 drives the tool to cut the material to be cut more smoothly, thereby improving the cutting efficiency and the cutting accuracy.

[0067] When a cycle of cutting is completed, the processed workpiece stays on the cutting platform. After entering the next cutting, rack 22 sends the workpiece to be processed to the cutting platform. The workpiece to be processed is pushed out of the cutting platform after contacting the processed workpiece. At this time, the workpiece to be processed stays in the cutting platform area after rack 22 reaches the right end limit position, and rack 1 12 starts to move to the left for cutting.

[0068] 2. Apply it to material transportation scenarios

[0069] When the reversing reciprocating multi-output mechanism is used in a material conveying scenario, the gear assembly 1 can be used as a feeding assembly, and the gear assembly 2 can be combined with the linear quick-elastic assembly as a reversing assembly. That is, in the material conveying scenario, the right side of the gear assembly 1 is the previous process, that is, the material enters the reversing reciprocating multi-output mechanism from the right side of the gear assembly 1. A push plate can be connected to the linear quick-elastic assembly, and the push plate is arranged along the length direction of the guide rail 41 and the push plate is fixed on the side surface of the slider 421 opposite to the spring 1 43. In the actual operation process, the conveying direction of the material can be changed by adjusting the direction of the gear assembly 2, and the linear quick-elastic assembly can be used as a driving source for driving the material conveyed from the gear assembly 1 to turn. In this application scenario, the gear 3 32 and the gear 2 21 can be connected by a universal coupling or a bevel gear, and the rack 1 12 and the rack 2 22 can also be connected by a section of conveyor belt, through which the material conveyed by the rack 1 12 can be conveyed to the gear assembly 2. In actual operation, a suitable universal coupling or bevel gear is selected according to the specific direction of the required steering, so as to achieve the purpose of changing the direction of the gear assembly 2.

[0070] In a material conveying scenario, the rack 12 may be connected to a placement plate for placing the material to be transported, or any other device in the prior art that can place the material to be transported.

[0071] The specific operation of the entire reversing reciprocating multi-output mechanism in the material conveying scenario is as follows: First, adjust the angle between gear assembly 2 and gear assembly 1 according to the actual material conveying needs to achieve the purpose of changing direction during material conveying.

[0072] The rocker 333 is set to the extreme position 51 as the initial state of the reversing reciprocating multi-output mechanism. At this time, the motor is started to rotate clockwise, the gear 3 32 rotates clockwise, the gear 2 21 drives the gear 1 11 and the gear 3 32 to rotate counterclockwise respectively, the gear 1 11 drives the rack 1 12 to move rightward, and the gear 2 21 drives the rack 2 22 to move rightward. When the rack 1 12 moves to the rightmost end, the material of the previous process can be placed on the placement plate fixedly connected to the rack 1 12, and the rack 1 12 drives the material to be transported from right to left through the placement plate. When the material of the rack 1 12 moves to the conveyor belt, the material will enter the conveyor belt between the rack 1 12 and the rack 2 22 due to inertia, and the conveyor belt will transport the material from the rack 1 12 to the rack 2 22. When the rack 12 moves to the leftmost end, the material on the conveyor belt also moves to the rack 22. The rack 22 also moves to the leftmost end. Under the action of the limit block 245, the limit block 221 will move from the right side of the connecting block 422 to the left side. At this time, the limit block 221 has no force on the connecting block 422. The slider 421 and the connecting block 422 move to the right under the elastic force of the spring 143, and drive the push plate fixedly connected to the slider 421 to push the material on the conveyor belt to the next process. In the material conveying scenario, by setting a steering gear between the gear 21 and the gear 32, it can realize the reversing operation during the material conveying process. At the same time, by setting a linear fast-elastic component, it can provide a driving force for the material that needs to be turned, so that the push plate can turn the material.

[0073] It can be understood that the linear quick-action assembly can also convert the relatively stable and slow rack movement of the rack 12 into a linear quick motion, thereby achieving the ability to divert the material while quickly pushing the material into the next process.

[0074] In the material conveying scenario, since the reversing reciprocating multi-output mechanism is provided with a crank rocker device 33, according to the characteristics of the crank rocker device 33, when the rocker 333 moves from the extreme position 1 51 to the extreme position 2 52, it takes a short time, and the material on the conveyor belt can be quickly turned and pushed into the next process. In addition, when the rocker 333 moves from the extreme position 2 52 to the extreme position 1 51, the rack 12 moves from the right side to the left side. In this process, due to the characteristics of the crank rocker device 33, this movement process takes a long time and is slow, which reduces the impact and vibration of the conveyed material during this transportation process, and achieves the purpose of protecting the material during the transportation process.

[0075] The above describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
