Description

Technical Field

[0001] This application relates to the field of button attaching machines, and in particular to an automatic button attaching machine. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. Most coal mines in my country are underground coal mines, which typically involve excavating tunnels underground to extract coal.

[0003] When mining coal, belt conveyors are typically used for transport. Installing or maintaining the belts of these conveyors usually requires a fastening machine. Traditional fastening machines require control via ground circuits, which is dangerous at the bottom of the mine. Manual fastening can lead to quality issues due to varying user strength. Therefore, a semi-automatic fastening machine was designed. This machine uses both pneumatic and manual control for positioning and fastening. The pneumatic control of the machine head swings to fasten the fastener, while manual pulling of the handle moves the machine along a processing track via a stepping component. The processing track has multiple evenly spaced processing holes. The pneumatically controlled head swinging action effectively replaces manual pressing. However, each fastener requires manual pulling of the handle, making it difficult and inconvenient for operators when fastening a large number of fasteners. Summary of the Invention

[0004] In order to realize the automatic operation and movement of the pneumatically controlled button attaching machine, this application provides an automatic button attaching machine.

[0005] The automatic button-attaching machine provided in this application adopts the following technical solution:

[0006] An automatic button-attaching machine includes a housing, a head, and a stepping assembly. A main cylinder and an auxiliary cylinder are mounted on the housing. A first adjusting assembly for adjusting the extension and retraction of the auxiliary cylinder's piston rod is disposed between the main cylinder and the auxiliary cylinder. A second adjusting assembly for adjusting the extension and retraction of the main cylinder's piston rod is disposed between the auxiliary cylinder and the housing. The auxiliary cylinder is a rack and pinion rotary cylinder, with a drive gear rotatably connected to it. A transmission gear for controlling the swinging of the head is rotatably connected to the housing. The drive gear meshes with the transmission gear. A shifting rocker for controlling the stepping assembly to drive the button-attaching machine is also rotatably connected to the housing. A rack that meshes with the transmission gear is fixedly connected to the shifting rocker.

[0007] By adopting the above technical solution, the main cylinder is vented in the forward direction, causing the piston rod of the main cylinder to extend. The extension of the piston rod affects the first adjustment component, which controls the movement of the piston rod of the auxiliary cylinder. The drive gear on the auxiliary cylinder rotates, which in turn drives the transmission gear to rotate. The rotation of the transmission gear drives the rack to rotate, controlling the stepping component to drive the button-attaching machine to move on the external processing track and controlling the machine head to swing for button-attaching processing. At the same time, the rotation of the drive gear also affects the operation of the second adjustment component. The second adjustment component controls the main cylinder to vent in the reverse direction, causing the piston rod of the main cylinder to retract. After the piston rod of the main cylinder retracts, it again affects the first adjustment component, which controls the piston rod of the auxiliary cylinder to move in the reverse direction. The drive gear on the auxiliary cylinder rotates in the reverse direction, controlling the stepping component and the machine head to reset. The reverse rotation of the drive gear affects the operation of the second adjustment component, which controls the main cylinder to vent in the forward direction, returning it to the initial state. This achieves automatic operation and movement of the button-attaching machine by starting control.

[0008] Preferably, the first adjusting component includes a toggle block fixedly connected to the piston rod of the main cylinder, a first reversing valve disposed on the housing, and a second reversing valve disposed on the housing. Both the first and second reversing valves are connected to external air passages. A first air passage is connected to the first reversing valve, and a second air passage is connected to the second reversing valve. The first air passage is connected to one end of the auxiliary cylinder, and the second air passage is connected to the other end of the auxiliary cylinder. A first valve stem for controlling the opening and closing of the first air passage is disposed on the first reversing valve, and a second valve stem for controlling the opening and closing of the second air passage is disposed on the second reversing valve. The toggle block can move the first valve stem and the second valve stem, and the distance between the first valve stem and the second valve stem is greater than the length of the toggle block.

[0009] By adopting the above technical solution, when the main cylinder is vented in the forward direction and the piston rod of the main cylinder extends, the actuating block will move along with the extension of the piston rod of the main cylinder. When the piston rod of the main cylinder extends to its maximum length, the actuating block actuates the second reversing valve, which opens. At this time, the first reversing valve closes, allowing the auxiliary cylinder to receive air in one direction. Similarly, when the main cylinder is vented in the reverse direction and the piston rod of the main cylinder retracts, the actuating block will move along with the extension of the piston rod of the main cylinder. When the piston rod of the main cylinder retracts to its minimum length, the actuating block actuates the first reversing valve, which opens. At this time, the second reversing valve closes, allowing the auxiliary cylinder to receive air in one direction, thus realizing the extension and retraction of the piston rod of the auxiliary cylinder.

[0010] Preferably, the second adjusting assembly includes a transmission rod fixedly connected to the transmission gear, a connecting shell fixedly connected to the housing, a lever slidably connected to the connecting shell, a pressure block rotatably connected to the housing, and a third reversing valve fixedly connected to the housing. The transmission rod is used to move the lever to slide on the connecting shell. A movable column is fixedly connected to the end of the lever away from the second hook. An oblong hole is provided on the pressure block, and the movable column is located in the oblong hole. A spring is fixedly connected to the housing, and the end of the spring away from the housing is fixedly connected to the pressure block. The third reversing valve is connected to an external air passage. A third air passage and a fourth air passage are connected to the third reversing valve. The third air passage is connected to one end of the main cylinder, and the fourth air passage is connected to the other end of the main cylinder. A third valve stem is provided on the third reversing valve to control the opening and closing of the third and fourth air passages. The pressure block can press the third valve stem.

[0011] By adopting the above technical solution, when the piston rod of the auxiliary cylinder moves, the movement of the piston rod is manifested by the rotation of the drive gear. When the second air passage is connected and the first air passage is closed, the drive gear rotates, which drives the transmission gear to rotate. The rotation of the transmission gear drives the transmission rod to move, and the movement of the transmission rod causes the lever to slide. The sliding of the lever causes the moving column to move, and the movement of the moving column causes the pressure block to rotate and press the third valve rod, causing the third reversing valve to switch, changing the direction of the airflow into the main cylinder, thus realizing the control of the retraction of the piston rod of the main cylinder. At the same time, when the pressure block rotates, the pressure block is pulled by the spring. When the first air passage is connected and the second air passage is closed, the drive gear rotates in the opposite direction, which drives the transmission gear to rotate. The rotation of the transmission gear drives the transmission rod to move. At this time, the transmission rod disengages from the lever, and the spring causes the pressure block to reset. The pressure block releases the pressure on the third valve rod, restoring the direction of the airflow into the main cylinder, thus realizing the control of the extension of the piston rod of the main cylinder.

[0012] Preferably, a first hook is integrally formed on the transmission rod, and a second hook is integrally formed on the lever, wherein the first hook and the second hook cooperate with each other.

[0013] By adopting the above technical solution, and with the setting of the first hook and the second hook, when the transmission rod moves, the first hook on the transmission rod will engage with the second hook on the lever, causing the lever to slide. When the transmission rod returns to its original position, the first hook on the transmission rod will disengage from the second hook on the lever.

[0014] Preferably, the housing is provided with a hand-operated valve, which is connected to an external air passage pipe. A fifth air passage pipe and a sixth air passage pipe are connected to the hand-operated valve. The end of the fifth air passage pipe away from the hand-operated valve is connected to the first reversing valve and the second reversing valve. The end of the sixth air passage pipe away from the hand-operated valve is connected to a shuttle valve, which is fixedly connected to the second air passage pipe.

[0015] By adopting the above technical solution, the hand-operated valve is used to control the air intake of the first and second directional valves. When the system stops running, pulling the hand-operated valve closes the fifth air passage and opens the sixth air passage. At this time, the gas connected in the sixth air passage will enter the second air passage through the shuttle valve and go to the auxiliary cylinder. At this time, the first air passage closes, the piston rod of the auxiliary cylinder moves and causes the third directional valve to switch, causing the piston rod of the main cylinder to retract, thus realizing the system reset after the air supply stops.

[0016] Preferably, an induction check valve is fixedly connected to the first gas pipeline, and the second gas pipeline is connected to the induction check valve.

[0017] By adopting the above technical solution and by setting the induced check valve, it can be ensured that the system works normally when the pressure block is released from the third valve stem, and that the pressure block will not release the pressure on the third valve stem due to accidental introduction of a small amount of gas.

[0018] Preferably, the stepping assembly includes a slide fixedly connected to the housing, a slide block slidably connected to the slide, a first connecting rod rotatably connected to the slide block, a second connecting rod rotatably connected to the first connecting rod, and a third connecting rod rotatably connected to the second connecting rod. One end of the displacement rocker is rotatably connected to the slide block. A push block for pushing the button-attaching machine to move on the processing track is fixedly connected to the third connecting rod. One end of the second connecting rod is rotatably connected to the slide, and the other end of the second connecting rod is rotatably connected to a torsion spring. The end of the torsion spring away from the second connecting rod is connected to the third connecting rod.

[0019] By adopting the above technical solution, the displacement rocker rotates, the sliding block slides on the slide, and the sliding of the slide drives the first connecting rod to move. Since the hinge position of the first connecting rod and the second connecting rod is located in the middle of the second connecting rod, the distance between the first connecting rod and the second connecting rod will first increase and then decrease during the sliding of the slide. The swing of the second connecting rod will drive the third connecting rod to swing. The pushing block of the third connecting rod will first abut against the external processing track to push the button-attaching machine to move, and then reset, thus realizing the movement of the button-attaching machine. During the pushing process of the third connecting rod, the torsion spring keeps the third connecting rod in contact with the external processing track.

[0020] Preferably, a handle is fixedly connected to the housing to facilitate moving the housing.

[0021] By adopting the above technical solution and with the handle, the user can move the button-attaching machine by the handle, which facilitates the movement of the button-attaching machine.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By utilizing the first and second adjustment components, an automatic air circulation system is constructed on the button attaching machine, enabling the automatic operation and movement of the pneumatically controlled button attacher;

[0024] 2. By using the hand-operated valve, the fifth air line, the sixth air line, and the shuttle valve, an automatic reset cycle is constructed, which realizes the automatic reset of each moving part in the system when the button attacher stops working;

[0025] 3. By setting up an induced check valve, the situation where the pressure block releases its pressure on the third valve stem due to accidental release is effectively reduced. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an automatic button-attaching machine.

[0034] like Figure 1 , Figure 2 , Figure 3As shown, an automatic button-attaching machine includes a housing 1, a machine head 2, and a stepping assembly 3. The housing 1 has an integrally formed handle 4000 for easy movement. A main cylinder 4 and an auxiliary cylinder 5 are bolted to the housing 1. A hand-operated valve 600 is connected to an external air passage. A first adjusting assembly 6 is provided between the main cylinder 4 and the auxiliary cylinder 5 to adjust the extension and retraction of the piston rod of the auxiliary cylinder 5. The auxiliary cylinder 5 is a rack and pinion rotary cylinder (type 20), with a drive gear 8 rotatably connected to it. The extension and retraction of the piston rod of the auxiliary cylinder 5 is achieved by the rotation of the drive gear 8. The first adjusting assembly 6 includes a toggle block 61, a first reversing valve 62, and a second reversing valve 63. The toggle block 61... Fixedly connected to the piston rod of the main cylinder 4, the first reversing valve 62 and the second reversing valve 63 are both fixedly connected to the same side of the housing 1 by bolts. The hand-operated valve 600 is connected to the fifth air passage pipe 700 and the sixth air passage pipe 800. In this embodiment, the hand-operated valve 600 is preferably a five-port two-position hand-operated valve 600. The fifth air passage pipe 700 is connected to the first reversing valve 62 and the second reversing valve 63. The first reversing valve 62 is connected to the first air passage pipe 30, and the second reversing valve 63 is connected to the second air passage pipe 40. The end of the first air passage pipe 30 away from the first reversing valve 62 is connected to the lower side of the auxiliary cylinder 5, and the end of the second air passage pipe 40 away from the second reversing valve 63 is connected to... Connected to the upper side of the auxiliary cylinder 5, when the first air passage 30 is connected and the second air passage 40 is closed, the piston rod of the auxiliary cylinder 5 extends. Similarly, when the second air passage 40 is connected and the first air passage 30 is closed, the piston rod of the auxiliary cylinder 5 retracts. An induction check valve 1000 is installed on the first air passage 30, and the induction check valve 1000 is also connected to the second air passage 40. A first valve stem 50 for controlling the opening and closing of the first air passage 30 is provided on the first reversing valve 62, and a second valve stem 60 for controlling the opening and closing of the second air passage 40 is provided on the second reversing valve 63. Both the first valve stem 50 and the second valve stem 60 are located on the running trajectory of the toggle block 61. The valve stem 50 and the second valve stem 60 are the same size. The distance between the first valve stem 50 and the second valve stem 60 is greater than the length of the actuating block 61. Both ends of the actuating block 61 are provided with grooves that cooperate with the first valve stem 50 and the second valve stem 60. When the piston rod of the main cylinder 4 is at its minimum extension distance, the actuating block 61 presses the first valve stem 50 to open the first air passage 30. When the piston rod of the main cylinder 4 is at its maximum extension distance, the actuating block 61 presses the second valve stem 60 to open the second air passage 40. Since the length of the actuating block 61 is less than the distance between the first valve stem 50 and the second valve stem 60, the actuating block 61 will not press the first valve stem 50 and the second valve stem 60 at the same time.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a second adjusting assembly 7 for adjusting the extension and retraction of the piston rod of the main cylinder 4 is provided between the auxiliary cylinder 5 and the housing 1. A transmission gear 9 is rotatably connected to the housing 1, and the transmission gear 9 meshes with the drive gear 8. The second adjusting assembly 7 includes a transmission rod 71, a connecting shell 72, a lever 73, a pressure block 74, and a third reversing valve 75. The transmission rod 71 is integrally formed on the transmission gear 9, and a first hook 400 is integrally formed at the end of the transmission rod 71 away from the transmission gear 9. The lever 73 is close to the transmission gear 9. One end of the lever 73 is integrally formed with a second hook 500, which engages with the first hook 400. The connecting shell 72 is fixedly connected to the housing 1 by bolts. The lever 73 is slidably connected to the connecting shell 72. The pressure block 74 is rotatably connected to the inside of the housing 1. The pressure block 74 has an oblong hole 80 located on its lower side. The end of the lever 73 near the pressure block 74 is integrally formed with a moving post 70, which is slidably connected to the oblong hole 80. The housing 1 is also fixedly connected to... A spring 90 is included, with its end away from the housing 1 fixedly connected to the upper side of the pressure block 74. A third directional valve 75 is bolted into the housing 1 and connected to an external air passage. A third air passage 100 and a fourth air passage 200 are also connected to the third directional valve 75. The end of the third air passage 100 away from the third directional valve 75 is connected to the left side of the main cylinder 4, and the end of the fourth air passage 200 away from the third directional valve 75 is connected to the right side of the main cylinder 4. When the third air passage 100 is connected and the fourth air passage 200 is closed, the piston rod of the main cylinder 4 retracts. Similarly, when the fourth air passage 200 is connected and the third air passage 100 is closed, the piston rod of the main cylinder 4 extends. The third directional valve 75 is provided with a third valve rod 300 for controlling the opening and closing of the third air passage 100 and the fourth air passage 200. The third valve rod 300 is located on the side of the pressure block 74 away from the spring 90, and the pressure block 74 can rotate to press the third valve rod 300.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, during use, the external air pipeline is connected and the hand-operated valve 600 is pulled to open the fifth air pipeline 700. The gas from the external air pipeline will pass through the fifth air pipeline 700 to the first air pipeline 30 and the second air pipeline 40. However, since the first reversing valve 62 is open and the second reversing valve 63 is closed in the initial state, the gas flowing into the fifth air pipeline 700 will all pass through the first reversing valve 62 and enter the lower side of the auxiliary cylinder 5, causing the piston rod of the auxiliary cylinder 5 to extend, the drive gear 8 to rotate, the rotation of the drive gear 8 to drive the transmission gear 9 to rotate, and the rotation of the transmission gear 9 to drive the transmission rod 7. 1. Movement: The movement of transmission rod 71 causes lever 73 to slide on connecting housing 72. The movement of lever 73 drives pressure block 74 to rotate, spring 90 is stretched, and pressure block 74 presses the third valve stem 300, causing the third reversing valve 75 to reverse, changing the airflow direction into main cylinder 4. The piston rod of main cylinder 4 extends. During the extension of the piston rod of main cylinder 4, the actuating block 61 disengages from the first valve stem 50. At this time, both the first reversing valve 62 and the second reversing valve 63 are closed, and external airflow will not enter the fifth air passage pipe 700. However, due to the self-locking of the mechanical structure, the third valve stem 300 remains pressed. The state of the main cylinder 4 causes the piston rod to extend continuously. When the piston rod of the main cylinder 4 extends to its maximum extension distance, the actuating block 61 will press the second valve rod 60. At this time, the second reversing valve 63 opens, and the gas from the external air passage will pass through the fifth air passage 700 into the second air passage 40. At this time, air enters from the upper side of the auxiliary cylinder 5, the piston rod of the auxiliary cylinder 5 retracts, the drive gear 8 rotates, the rotation of the drive gear 8 drives the transmission gear 9 to rotate, the rotation of the transmission gear 9 drives the transmission rod 71 to move, the movement of the transmission rod 71 releases the actuation of the lever 73, and under the action of the spring 90, the pressure block 7... 4. Reset: Release the pressure on the third valve stem 300, and the third directional valve 75 returns to its initial state. The piston rod of the main cylinder 4 retracts. Similarly, during the retraction of the piston rod of the main cylinder 4, the toggle block 61 will disengage from the second valve stem 60. At this time, both the first directional valve 62 and the second directional valve 63 are closed, and external airflow will not enter the fifth air passage 700. However, due to the self-locking of the mechanical structure, the third valve stem 300 remains in its initial state, causing the piston rod of the main cylinder 4 to continue to retract until the piston rod of the main cylinder 4 presses the first valve stem 50 again, causing the first directional valve 62 to open and start the next cycle.

[0037] like Figure 2 As shown, a shuttle valve 900 is installed on the second air passage pipe 40, and the sixth air passage pipe 800 is also connected to the shuttle valve 900. When in use, when the air circulation in the button-attaching machine is closed, the hand valve 600 is pulled to open the sixth air passage pipe 800. The gas from the external air passage pipe flows into the shuttle valve 900 through the sixth air passage pipe 800, and then into the second air passage pipe 40. At this time, air enters from the upper side of the auxiliary cylinder 5, causing the third reversing valve 75 to return to its initial state, and the piston rod of the main cylinder 4 to retract, so that it can automatically return to its initial state when it stops using.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the transmission gear 9 is coaxially fixedly connected to the machine head 2. The machine head 2 swings as the transmission gear 9 rotates. A displacement rocker 10 is also rotatably connected to the housing 1 to control the movement of the stepping component 3 on the external processing track. The displacement rocker 10 has a rack 20 integrally formed on it that meshes with the transmission gear 9. The stepping component 3 includes a slide 31, a sliding block 32, a first connecting rod 33, a second connecting rod 34, and a third connecting rod 35. The slide 31 is fixedly connected to the housing 1 by bolts, and the sliding block 32 is slidably connected to the slide 31. On the base 31, the end of the shifting rocker arm 10 away from the housing 1 is hinged to the sliding block 32. The first connecting rod 33 is rotatably connected to the sliding block 32. One end of the second connecting rod 34 is rotatably connected to the slide base 31, and the other end of the second connecting rod 34 is fixedly connected to a torsion spring 3000. The end of the torsion spring 3000 away from the second connecting rod 34 is connected to the third connecting rod 35. The end of the first connecting rod 33 away from the housing 1 is rotatably connected to the middle position of the second connecting rod 34. The third connecting rod 35 is integrally formed with a mechanism for pushing the button-attaching machine in the process of adding... When the drive gear 9 rotates, the machine head 2 swings to fasten the buttons. Simultaneously, the rotation of the drive gear 9 also drives the shifting rocker 10 to swing, causing it to move upwards. The slider also moves upwards. Since the first connecting rod 33 is rotatably connected to the middle position of the second connecting rod 34, the second connecting rod 34 reaches its maximum swing distance when the first connecting rod 33 is parallel. As the slider moves upwards, the swing amplitude of the second connecting rod 34 first increases and then decreases. Because the maximum upward movement is less than the maximum downward movement, the swing distance of the second connecting rod 34 at its highest point is less than the swing distance at its lowest point. During the upward movement of the slider, the drive block 2000 on the third connecting rod 35 pushes the button fastening machine a fixed distance on the processing track. During the downward movement of the slider, the drive block 2000 on the third connecting rod 35 moves to the next pushing position under the action of the torsion spring 3000, thus achieving repeated movement of the button fastening machine on the processing track.

[0039] The implementation principle of an automatic button-attaching machine according to an embodiment of this application is as follows: When put into actual use, the button-attaching machine is moved to the processing track, and the slide 31 is installed on the processing track. The external air pipeline is connected, and the hand-operated valve 600 is pushed to connect the fifth air pipeline 700, so that the button-attaching machine can automatically process and move. When processing stops, the hand-operated valve 600 is pushed to connect the sixth air pipeline 800, so that the button-attaching machine can automatically reset, which is convenient for use.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
