Description

Technical Field

[0001] This utility model belongs to the field of pulley manufacturing technology, specifically a pulley lower support feeding device. Background Technology

[0002] In the production of pulleys, the loading of the lower support is a key process that directly affects production efficiency and product quality. A vibratory feeder is used to arrange the pulley supports one by one and output them to the designated position through vibration. Then, pneumatic fingers open and clamp the pulley supports. After clamping, the pneumatic fingers retract and carry the pulley supports up or move them to the next station.

[0003] If the design of the feeding mechanism is not advanced enough or the degree of automation is not high, it may lead to problems such as slow feeding speed and poor stability. If the equipment in the feeding mechanism, such as vibratory feeder, pneumatic fingers, and lifting mechanism, is not designed properly or maintained properly, it may have a high failure rate. This will not only affect the production schedule, but also increase maintenance costs and downtime.

[0004] Uneven feeding by the vibratory feeder and inaccurate gripping by the pneumatic fingers during use can affect production efficiency and product quality. Furthermore, when transporting the lower pulley support, multiple sets of lower pulley supports may stick together, affecting the subsequent operation of picking up the lower pulley support and causing it to fall off. Additionally, it is impossible to feed the lower pulley support from multiple angles. The vibratory feeder also generates noise during operation, affecting the working environment in the workshop. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a pulley lower support feeding device, which has the advantages of automatically separating the pulley lower support, feeding by changing the position and angle of the pulley lower support, and reducing the noise generated by the vibrating plate during operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pulley-supported feeding device, including a vibrating plate, a slide rail provided on the outer wall of the vibrating plate, a material blocking and conveying mechanism provided at the top of the slide rail, a support frame fixed at the bottom of the slide rail, a material release cylinder provided at the bottom of the slide rail, a second position sensor provided at the top of the slide rail, an assembly mechanism provided at the top of the material release cylinder, a connecting frame provided at one end of the assembly mechanism, and a noise reduction structure provided on the inner wall of the vibrating plate;

[0007] The material blocking and conveying mechanism includes a material blocking cylinder, a first position sensor, and an air blowing hole. The material blocking cylinder has two sets fixed to the top of the slide rail, and the first position sensor is installed at the bottom of the material blocking cylinder. The air blowing hole is fixed to the top of the slide groove of the slide rail.

[0008] Preferably, the air blowing holes are provided in three sets, and the air blowing holes are arranged at equal intervals about the central axis of the slide.

[0009] Preferably, the assembly mechanism includes a suction cup, a first connecting block, a rotary cylinder, and a connecting plate. The connecting plate is fixed to the side wall of the connecting frame. A second slider is provided on the side wall of the connecting plate. A support plate is fixed on the side wall of the connecting plate. A translation cylinder is provided at one end of the support plate. A second connecting block is fixed to the top of the second slider. A lifting cylinder is fixed to the top of the second connecting block. A first slider is fixed to the bottom of the lifting cylinder. A rotary cylinder is fixed to the bottom of the first slider. A first connecting block is fixed to the bottom of the rotary cylinder. A suction cup is provided at the bottom of the first connecting block.

[0010] Preferably, the suction cups are provided in two sets fixed to the bottom end of the first connecting block, and the suction cups are distributed at equal intervals about the central axis of the first connecting block.

[0011] Preferably, the outer wall of the first slider is provided with a groove, the outer wall of the second slider is provided with a slide rail, the top end of the first slider is fixed to the output end of the lifting cylinder, and the first slider and the second slider are slidably connected.

[0012] Preferably, the second slider has a groove on its side wall, and the connecting plate has a slide rail on its side wall, and the second slider and the connecting plate are slidably connected.

[0013] Preferably, the translation cylinder is welded to the side wall of the support plate, and a second slider is welded to the output end of the translation cylinder.

[0014] Preferably, the noise reduction structure includes a sound-guiding cavity, sound-absorbing cotton, and sound-damping plates. The sound-guiding cavity is opened on the inner wall of the vibrating disk, the interior of the sound-guiding cavity is filled with sound-absorbing cotton, and several sets of sound-damping plates are arranged inside the sound-guiding cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the coordination of components such as a material-blocking cylinder, a first position sensor, and an air-blowing hole. The material-blocking cylinder blocks material from the lower pulley support, preventing multiple lower pulley supports from approaching each other during transportation and affecting the accuracy of subsequent picking. The first position sensor sends a signal to the material-blocking cylinder after detecting a lower pulley support, causing the material-blocking cylinder's blocking rod to rise, allowing the lower pulley support to pass its current position. Furthermore, the material-blocking cylinder and the air-blowing hole are controlled by a solenoid valve. When the blocking rod is raised, the air-blowing hole blows air onto the lower pulley support, causing it to move to the end of the slide along the shape of the slide rail, thereby achieving the purpose of automatically separating the lower pulley supports.

[0017] This invention utilizes the cooperation of components such as a suction cup, a first connecting block, and a rotary cylinder. The suction cup can pick up the lower support of the pulley. After picking it up, the rotary cylinder can drive the first connecting block, the suction cup, and the lower support of the pulley to rotate, moving them to a suitable angle. The lifting cylinder can move the first slider and the rotary cylinder mounted on the first slider up and down. The suction cup can move the second slider and the first slider mounted on the second slider back and forth, allowing the lower support of the pulley to be placed onto the subsequent disc positioning fixture for pulley processing. This enables the device to load materials by changing the position and angle of the lower support of the pulley.

[0018] This invention, through the coordinated arrangement of components such as a sound-guiding cavity, sound-absorbing cotton, and a sound-damping plate, addresses the issue of noise generated during operation of the vibratory feeder. Since the vibratory feeder vibrates to transport the internal pulley support, this process generates significant noise, potentially impacting the physical and mental health of workshop workers. The sound-guiding cavity, sound-absorbing cotton, and sound-damping plate extend the noise propagation path and absorb it, effectively reducing the noise generated by the vibratory feeder during operation and thus ensuring a safe working environment within the workshop.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 7 As shown, this utility model provides a material feeding device for a pulley support, including a vibrating plate 1, a slide 2 provided on the outer wall of the vibrating plate 1, a material blocking and conveying mechanism 3 provided at the top of the slide 2, a support frame 4 fixed at the bottom of the slide 2, a material release cylinder 5 provided at the bottom of the slide 2, a second position sensor 6 provided at the top of the slide 2, an assembly mechanism 7 provided at the top of the material release cylinder 5, a connecting frame 8 provided at one end of the assembly mechanism 7, and a noise reduction structure 9 provided on the inner wall of the vibrating plate 1.

[0029] Using the above scheme: by starting the vibrating plate 1, the vibrating plate 1 arranges the pulley brackets one by one through vibration and outputs them to the designated position. The air blowing hole 303 blows the lower pulley bracket to the end of the slide 2 and then contacts the second position sensor 6. The second position sensor 6 sends a signal to start the material release cylinder 5. The material release cylinder 5 lifts the lower pulley bracket so that the suction cup 701 can contact and pick up the lower pulley bracket.

[0030] like Figures 1 to 7 As shown, the material blocking and conveying mechanism 3 includes a material blocking cylinder 301, a first position sensor 302, and air blowing holes 303. The material blocking cylinder 301 is provided with two sets fixed to the top of the slide rail 2, and the first position sensor 302 is provided at the bottom of the material blocking cylinder 301. The air blowing holes 303 are fixed to the top of the slide groove of the slide rail 2, and there are three sets of air blowing holes 303. The air blowing holes 303 are arranged at equal intervals about the central axis of the slide rail 2.

[0031] The above solution is adopted: the material blocking cylinder 301 can block the lower pulley support to prevent multiple lower pulley supports from getting close to each other during transportation and affecting the subsequent suction accuracy. The first position sensor 302 can send a signal to the material blocking cylinder 301 after detecting the lower pulley support. The material blocking rod of the material blocking cylinder 301 is raised so that the lower pulley support can pass the current position. The material blocking cylinder 301 and the air blowing hole 303 are controlled by a solenoid valve. When the material blocking rod is raised, the air blowing hole 303 blows air onto the lower pulley support, so that it moves to the end of the slide 2 through the shape of the slide 2.

[0032] like Figures 1 to 7 As shown, the assembly mechanism 7 includes a suction cup 701, a first connecting block 702, a rotary cylinder 703, and a connecting plate 708. The connecting plate 708 is fixed to the side wall of the connecting frame 8. A second slider 707 is provided on the side wall of the connecting plate 708. A sliding groove is provided on the side wall of the second slider 707. A slide rail is provided on the side wall of the connecting plate 708. The second slider 707 and the connecting plate 708 are slidably connected.

[0033] like Figures 1 to 7 As shown, a support plate 709 is fixed to the side wall of the connecting plate 708. A translation cylinder 710 is provided at one end of the support plate 709. The translation cylinder 710 is welded to the side wall of the support plate 709. A second slider 707 is welded to the output end of the translation cylinder 710. A second connecting block 706 is fixed to the top of the second slider 707. A lifting cylinder 705 is fixed to the top of the second connecting block 706. A first slider 704 is fixed to the bottom end of the lifting cylinder 705. A groove is formed on the outer wall of the first slider 704. The outer wall of 07 is provided with a slide rail. The top of the first slider 704 is fixed to the output end of the lifting cylinder 705. The first slider 704 and the second slider 707 are slidably connected. The bottom end of the first slider 704 is fixed with a rotary cylinder 703. The bottom end of the rotary cylinder 703 is fixed with a first connecting block 702. The bottom end of the first connecting block 702 is provided with a suction cup 701. Two sets of suction cups 701 are fixed to the bottom end of the first connecting block 702. The suction cups 701 are evenly distributed about the central axis of the first connecting block 702.

[0034] Using the above solution: the suction cup 701 can pick up the lower support of the pulley. After picking it up, the rotary cylinder 703 can drive the first connecting block 702, the suction cup 701 and the lower support of the pulley to rotate, so that its position is moved to a suitable angle. The lifting cylinder 705 can move the first slider 704 and the rotary cylinder 703 installed on the first slider 704 up and down. The suction cup 701 can move the second slider 707 and the first slider 704 set on the second slider 707 back and forth, so that the lower support of the pulley can be placed on the subsequent disc positioning fixture for pulley processing.

[0035] like Figures 1 to 7 As shown, the noise reduction structure 9 includes a sound-conducting cavity 901, sound-absorbing cotton 902, and a sound-damping plate 903. The sound-conducting cavity 901 is opened on the inner wall of the vibrating plate 1. The sound-conducting cavity 901 is filled with sound-absorbing cotton 902, and several sets of sound-damping plates 903 are arranged inside the sound-conducting cavity 901.

[0036] The above solution is adopted as follows: by opening a sound-guiding cavity 901 in the inner wall of the vibrating plate 1 and filling it with 902, when the sound encounters the sound-absorbing cotton 902 during propagation, it will be absorbed by the fibers and gaps inside and converted into heat energy and dissipated. Furthermore, by arranging sound-absorbing plates 903 at equal intervals inside the sound-guiding cavity 901, the sound-absorbing plates 903 can shrink the space inside the sound-guiding cavity 901, so that the sound will propagate to both ends after contacting 903 during propagation, thereby extending the sound propagation path and reducing noise inside the vibrating plate 1.

[0037] The working principle and usage process of this utility model are as follows: The material-blocking cylinder 301 blocks the lower pulley brackets, preventing multiple lower pulley brackets from approaching each other during transportation and affecting the subsequent suction accuracy. The first position sensor 302 sends a signal to the material-blocking cylinder 301 after detecting a lower pulley bracket, causing the material-blocking rod of the cylinder 301 to rise, allowing the lower pulley bracket to pass its current position. The material-blocking cylinder 301 and the air-blowing hole 303 are controlled by a solenoid valve. When the material-blocking rod is raised, the air-blowing hole 303 blows air onto the lower pulley bracket, causing it to move to the end of the slide 2. By activating the vibrating plate 1, the vibrating plate 1 arranges the pulley brackets one by one through vibration and outputs them to the designated positions. The air-blowing hole 303 then blows the lower pulley bracket to the end of the slide 2. When the second position sensor 6 is touched, it sends a signal to activate the material release cylinder 5. The material release cylinder 5 raises the lower pulley support, allowing the suction cup 701 to contact and pick up the lower pulley support. The suction cup 701 picks up the lower pulley support. After picking it up, the rotary cylinder 703 drives the first connecting block 702, the suction cup 701, and the lower pulley support to rotate, moving them to a suitable angle. The lifting cylinder 705 moves the first slider 704 and the rotary cylinder 703 mounted on the first slider 704 up and down. The suction cup 701 moves the second slider 707 and the first slider 704 mounted on the second slider 707 back and forth, allowing the lower pulley support to be placed into the subsequent disc positioning fixture for pulley processing.
