Description

Technical Field

[0001] This invention belongs to the technical field of mechanical automation, specifically a multi-specification round bar feeding device. Background Technology

[0002] Feeding devices are required in all production and processing equipment. The feeding device needs to convey materials in batches to the material to be processed, so as to facilitate the processing equipment to process the materials.

[0003] Currently, Chinese invention patent application CN104891141B discloses a method for using an automatic unloading device for round bar products. The automatic unloading device includes a unloading supply mechanism and a bar pushing and rotating mechanism, with the unloading supply mechanism positioned directly above the bar pushing and rotating mechanism. The unloading supply mechanism mainly consists of a hopper, a material-collecting rotating column, a material-collecting stop, a drive motor, and a synchronous belt. The bar pushing and rotating mechanism mainly consists of a lead screw, a receiving groove, and a motor. The automatic unloading device features a simple structure, convenient processing, installation, and debugging, and is suitable for modular application. This automatic unloading device is suitable for the automated unloading needs of cigarettes, filter rods, and other round bar-shaped objects in various applications.

[0004] Regarding the aforementioned related technologies, the inventors believe that in the process of feeding round rod-shaped objects of different specifications, the feeding device is difficult to apply to more specifications of materials, is prone to jamming, has a slow feeding speed, and has a complex driving logic, resulting in a small applicable range and low working efficiency. Summary of the Invention

[0005] To facilitate the feeding of round bars of different specifications and improve the applicability of the feeding device, this application provides a multi-specification round bar feeding device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-specification round bar feeding device includes a fixed frame, a feeding mechanism, and an adjusting mechanism, wherein the feeding mechanism and the adjusting mechanism are both connected to the fixed frame;

[0007] The feeding mechanism includes a first driving component and a feeding component, both of which are connected to a fixed frame. The first driving component drives the feeding component to complete feeding. The adjusting mechanism includes an adjusting component and a second driving component, which are connected to the second driving component.

[0008] The feeding assembly includes a feeding roller and a feeding member. The feeding roller is rotatably connected to a fixed frame. The fixed frame has multiple movable holes. The feeding member passes through the movable holes and moves within them. The adjusting assembly supports the feeding member. The second driving assembly drives the adjusting assembly to adjust the position of the feeding member. The first driving assembly drives the feeding roller to rotate. The feeding roller has a feeding groove along its length for placing round bars.

[0009] By adopting the above technical solution, the round bar is placed between the feed roller and the auxiliary rotating roller. The first drive assembly drives the feed roller to rotate, and the round bar enters the feed groove on the feed roller. During the rotation of the feed roller, the material-pushing component pushes excess round bars away from the feed groove, thereby reducing material jamming and improving the feeding speed. As the feed roller rotates, the round bar leaves the feed groove, completing the feeding process. When it is necessary to feed round bars of different specifications, the second drive assembly drives the adjustment assembly to move. The adjustment assembly drives the material-pushing component to move, thereby adjusting the position of the material-pushing component and thus adjusting the distance between the material-pushing component and the feed roller, thereby facilitating the feeding of round bars of different specifications.

[0010] Preferably, there are multiple feeding troughs, the feeding rollers are toothed, and the height of the side wall of the feeding trough in the feeding direction is higher than the height of the other side wall.

[0011] By adopting the above technical solution, during the rotation of the feed roller, the side with the higher sidewall of the feed trough is in front and the side with the lower sidewall of the feed trough is behind. The material pusher pushes away the excess round bars in the feed trough, thereby reducing the occurrence of material jamming. The feed roller rotates continuously in one direction, realizing continuous feeding of materials, thereby improving the feeding speed.

[0012] Preferably, the adjusting assembly includes two rotating shafts, the feeding component is connected to two fixed baffles, the fixed frame is located between the two fixed baffles, the two fixed baffles are rotatably connected to the two rotating shafts respectively, the two fixed baffles are slidably connected to the two rotating shafts respectively, a fixed shaft is rotatably connected to each of the two fixed baffles, the fixed shaft is fixedly connected to the fixed frame, a positioning pin is rotatably connected to each of the two rotating shafts, the positioning pin is fixedly connected to the fixed frame, and both rotating shafts are connected to the second driving assembly.

[0013] By adopting the above technical solution, the second drive component drives the two rotating shafts to move. The rotating shafts drive the material feeding component to move through the fixed baffle, thereby adjusting the position of the material feeding component and adjusting the distance between the material feeding component and the feed roller, thus facilitating the feeding of round bars of different specifications.

[0014] Preferably, the feeding component is an auxiliary rotating roller, with both ends of the auxiliary rotating roller rotatably connected to two fixed baffles respectively, and both ends of the auxiliary rotating roller passing through the two fixed baffles respectively. The first driving component drives the auxiliary rotating roller to rotate, and the second driving component drives the auxiliary rotating roller to swing.

[0015] By adopting the above technical solution, the first drive component drives the auxiliary roller to rotate. The auxiliary roller is close to the feed roller, and their linear velocities are in opposite directions. During the rotation of the feed roller, the side with the higher sidewall of the feed trough is in front, and the side with the lower sidewall is behind. The auxiliary roller always moves from the side with the higher sidewall to the side with the lower sidewall. During the rotation of the auxiliary roller, it pushes away the round bars outside the feed trough, thereby reducing material jamming and increasing the feeding speed. The second drive component drives the auxiliary roller to swing, thereby adjusting the distance between the auxiliary roller and the feed roller, and thus adjusting the feeding gap, facilitating the feeding of raw materials of different specifications.

[0016] Preferably, the material feeding component is a material feeding plate, and both ends of the material feeding plate are fixedly connected to two fixed baffles respectively.

[0017] By adopting the above technical solution, the material guide plate pushes the excess round bars away from the feed chute, thereby reducing the occurrence of material jamming and improving the feeding speed.

[0018] Preferably, the second drive assembly includes a second drive motor, which is fixedly connected to a fixed frame. The output shaft of the second drive motor passes through the fixed frame. A connecting rod is vertically fixedly connected to the output shaft of the second drive motor. A linkage rod is rotatably connected to the end of the connecting rod away from the second drive motor. The connecting rod and the linkage rod are slidably connected. A fixed rod is fixedly connected to the end of the linkage rod away from the connecting rod. The two ends of the fixed rod are respectively fixedly connected to two rotating shaft swing arms.

[0019] By adopting the above technical solution, the second drive motor is started, and the output shaft of the second drive motor drives the connecting rod to rotate. The connecting rod drives the linkage rod to move, and the linkage rod drives the fixed rod to move, thereby facilitating the adjustment of the position of the auxiliary rotating roller, and thus adjusting the distance between the feed roller and the auxiliary rotating roller.

[0020] Preferably, the first driving component includes a first driving motor, which simultaneously drives the feed roller and the auxiliary roller to rotate.

[0021] By adopting the above technical solution, the first drive motor is started, which drives the feed roller and the auxiliary rotating roller to rotate, thereby feeding the round bar.

[0022] Preferably, both sides of the two fixed baffles in the vertical direction are provided with limit pins, and the limit pins are fixedly connected to the fixed frame.

[0023] By adopting the above technical solution, the limiting pin limits the upper and lower positions of the fixed baffle, limiting the maximum and minimum gap between the feed roller and the auxiliary roller, thereby controlling the size of the feed gap and avoiding the occurrence of the auxiliary roller colliding with the feed roller and the excessive gap between the auxiliary roller and the feed roller.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] This invention incorporates a second drive motor and an auxiliary rotating roller. When the second drive motor is activated, its output shaft rotates a connecting rod, which in turn moves a linkage rod, which in turn moves a fixed rod. This allows for convenient adjustment of the position of the auxiliary rotating roller, thereby adjusting the distance between the feed roller and the auxiliary rotating roller. This makes it suitable for round bars of different specifications, thus expanding the applicability of the feeding device.

[0026] This invention employs a feeding roller and a feeding trough. During the rotation of the feeding roller, the side of the feeding trough with the higher side wall is in front, and the side with the lower side wall is behind. The auxiliary rotating roller always rotates from the side with the higher side wall to the side with the lower side wall. As the auxiliary rotating roller rotates, it pushes away any round bars outside the feeding trough, thereby reducing material jamming and increasing the feeding speed. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figure 1 and Figure 2 The first embodiment of the multi-specification round bar feeding device provided by the present invention includes a fixed frame 1, a feeding mechanism 2, and an adjusting mechanism 3. Both the feeding mechanism 2 and the adjusting mechanism 3 are connected to the fixed frame 1. The adjusting mechanism 3 adjusts the feeding mechanism 2, thereby facilitating the feeding of round bars of different specifications and improving the applicability of the feeding device.

[0039] Reference Figure 1 and Figure 2 The fixed frame 1 includes a base plate 11, and vertical plates 12 are vertically fixedly connected to both ends of the base plate 11. The feeding mechanism 2 includes a feeding component 21 and a first drive component 22. The feeding component 21 is connected to the two vertical plates 12, and the first drive component 22 is connected to the base plate 11. The first drive component 22 drives the feeding component 21 to complete the feeding.

[0040] Reference Figure 1 and Figure 2The feeding assembly 21 includes a feeding roller 211 and a feeding member 212. The two ends of the feeding roller 211 pass through two vertical plates 12 and are rotatably connected to them. Multiple movable holes are provided on each of the two vertical plates 12. The feeding member 212 is an auxiliary rotating roller 2121, which passes through and moves within the movable holes. The adjusting mechanism 3 supports the auxiliary rotating roller 2121 and adjusts its position.

[0041] Reference Figure 3 and Figure 4 The first drive assembly 22 drives the feed roller 211 and the auxiliary rotating roller 2121 to rotate. The auxiliary rotating roller 2121 is located between the feed roller 211 and the first drive assembly 22. The feed roller 211 has multiple feed grooves 213 of different sizes along its length. The feed roller (211) is toothed, and the feed grooves 213 are used to hold round bars. During the feeding process, the side with the higher sidewall of the feed groove 213 is in front, and the side with the lower sidewall is behind. During the rotation of the feed roller 211, the feed roller 211 and the auxiliary rotating roller 2121 rotate in the same direction. R1 is greater than R2. The auxiliary rotating roller 2121 always turns from the side with the higher sidewall of the feed groove 213 to the side with the lower sidewall. During the rotation of the auxiliary roller 2121, the round bar outside the feed trough 213 is pushed away, thereby reducing the occurrence of material jamming and increasing the feeding speed.

[0042] Refer to 1 and Figure 2 The first drive assembly 22 includes a first drive motor 221, which is fixedly connected to the base plate 11. One end of both the feed roller 211 and the auxiliary roller 2121 is fixedly connected to a pulley 214. A belt 222 is sleeved on the output shaft of the first drive motor 221, and the belt 222 is sleeved on the pulleys 214 on the feed roller 211 and the auxiliary roller 2121. The auxiliary roller 2121 is located between the feed roller 211 and the first drive motor 221. When the first drive motor 221 is started, its output shaft drives the feed roller 211 and the auxiliary roller 2121 to rotate via the belt 222, thereby feeding the round bar.

[0043] Reference Figure 2 and Figure 3 The adjustment mechanism 3 includes an adjustment component 31 and a second drive component 32, with the adjustment component 31 connected to the second drive component 32. The second drive component 32 drives the adjustment component 31 to adjust the position of the auxiliary rotating roller 2121, thereby adjusting the gap between the auxiliary rotating roller 2121 and the feed roller 211, thus facilitating the feeding of round bars of different specifications.

[0044] Reference Figure 1 and Figure 3 The adjusting assembly 31 includes two rotating shafts 311, both of which are connected to the second drive assembly 32. Fixed baffles 312 are rotatably connected to both ends of the auxiliary roller 2121. Two vertical plates 12 are located between the two fixed baffles 312, which are rotatably connected to the two rotating shafts 311 and slidably connected to them. Fixed shafts 313 are rotatably connected to the two fixed baffles 312 and are fixedly connected to the vertical plates 12. Positioning pins 314 are rotatably connected to the two rotating shafts 311 and are fixedly connected to the two vertical plates 12.

[0045] Reference Figure 2 When it is necessary to feed round bars of different specifications, the second drive assembly 32 drives the two rotating shafts 311 to move. The rotating shafts 311 drive the auxiliary rotating roller 2121 to move through the fixed baffle 312, thereby adjusting the position of the auxiliary rotating roller 2121 and adjusting the distance between the auxiliary rotating roller 2121 and the feed roller 211, so as to facilitate the feeding of round bars of different specifications. The fixed shaft 313 supports and fixes the fixed baffle 312, improving the stability and reliability of the device.

[0046] Reference Figure 2 Limit pins 315 are provided on both sides of the two fixed baffles 312 in the vertical direction, and the limit pins 315 are fixedly connected to the fixed frame 1. The limit pins 315 limit the fixed baffles 312 in the upper and lower directions, limiting the maximum and minimum gap between the feed roller 211 and the auxiliary rotating roller 2121, thereby controlling the size of the feed gap.

[0047] Reference Figure 1 and Figure 2 The second drive assembly 32 includes a second drive motor 321, which is fixedly connected to the base plate 11. The output shaft of the second drive motor 321 passes through the vertical plate 12. A connecting rod 322 is fixedly connected to the output shaft of the second drive motor 321. A linkage rod 323 is rotatably connected to the end of the connecting rod 322 away from the second drive motor 321. The connecting rod 322 and the linkage rod 323 are slidably connected. The end of the linkage rod 323 away from the connecting rod 322 is fixedly connected to a fixed rod 324. When the second drive motor 321 is started, the output shaft of the second drive motor 321 drives the connecting rod 322 to rotate. The connecting rod 322 drives the linkage rod 323 to move, and the linkage rod 323 drives the fixed rod 324 to move, thereby facilitating the adjustment of the position of the auxiliary rotating roller 2121, and thus adjusting the distance between the feed roller 211 and the auxiliary rotating roller 2121.

[0048] Working principle: Start the first drive motor 221. The first drive motor 221 drives the pulley 214 to rotate through the belt 222. The pulley 214 drives the feed roller 211 and the auxiliary rotating roller 2121 to rotate. The round bar is placed between the feed roller 211 and the auxiliary rotating roller 2121. During the rotation of the feed roller 211, the round bar enters the feed trough 213. The rotation of the feed roller 211 drives the round bar to complete the feeding.

[0049] During the rotation of the feed roller 211, the side with the higher sidewall of the feed chute 213 faces forward, and the side with the lower sidewall faces backward. The higher sidewall pushes away excess bar material, thereby reducing the occurrence of material jamming. During the rotation of the feed roller 211, the feed roller 211 operates continuously in one direction, realizing continuous feeding of materials, thereby improving the feeding speed.

[0050] When feeding round bars of different specifications, the second drive motor 321 is activated. The output shaft of the second drive motor 321 drives the connecting rod 322 to rotate, which in turn drives the linkage rod 323 to move. The linkage rod 323 then drives the fixed rod 324 to move, thereby facilitating the adjustment of the position of the auxiliary rotating roller 2121 and consequently adjusting the distance between the feeding roller 211 and the auxiliary rotating roller 2121. This makes it suitable for round bars of different specifications, thus improving the applicability of the feeding device.

[0051] The second embodiment of the multi-specification round bar feeding device provided by the present invention differs from the first embodiment in that: (Refer to...) Figure 5 , Figure 6 and Figure 7 The feed roller 211 is located between the auxiliary roller 2121 and the first drive motor 221. During the feeding process, the length of R1 is greater than R2. The side of the feed trough 213 with the higher side wall is in front, and the side with the lower side wall is behind. The feed roller 211 and the auxiliary roller 2121 rotate in the same direction, from the side with the higher side wall to the side with the lower side wall. During the rotation of the auxiliary roller 2121, it pushes away the round bars outside the feed trough 213, thereby reducing the occurrence of material jamming and improving the feeding speed.

[0052] Working principle: Start the first drive motor 221. The first drive motor 221 drives the pulley 214 to rotate through the belt 222. The pulley 214 drives the feed roller 211 and the auxiliary rotating roller 2121 to rotate. The round bar is placed between the feed roller 211 and the auxiliary rotating roller 2121. During the rotation of the feed roller 211, the round bar enters the feed trough 213. The rotation of the feed roller 211 drives the round bar to complete the feeding.

[0053] During the rotation of the auxiliary roller 2121, the round bar outside the feed trough 213 is pushed away, thereby reducing the occurrence of material jamming and increasing the feeding speed.

[0054] The third embodiment of the multi-specification round bar feeding device provided by the present invention differs from the first embodiment in that: (Refer to...) Figure 8 and Figure 9 The feeding component 212 is a feeding plate 2122, and both ends of the feeding plate 2122 are fixedly connected to two fixed baffles 312 respectively. The belt 222 is sleeved on the pulley 214 of the feed roller 211.

[0055] Working principle: Start the first drive motor 221. The first drive motor 221 drives the pulley 214 to rotate through the belt 222. The pulley 214 drives the feed roller 211, placing the round bar on the feed roller 211. During the rotation of the feed roller 211, the round bar enters the feed groove 213. The feed roller 211 rotates, thereby driving the round bar to complete the feeding.

[0056] During the rotation of the feed roller 211, the pusher plate 2122 pushes away the round bar outside the feed trough 213, thereby reducing the occurrence of jamming and increasing the feeding speed.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
