Description

Technical Field

[0001] The utility model relates to the technical field of workpiece feeding machinery, in particular to a fast and stable single machine for feeding without visual lifting. Background Art

[0002] In the current market, due to the increasing demand for packaging of granular, flake, capsule, toy building blocks and other materials, more and more lifting and feeding machines have appeared. Lifting and feeding machines are generally divided into visual lifting and feeding machines and non-visual lifting and feeding machines. The non-visual lifting and feeding machines on the market generally include a lifting and feeding mechanism, a straight vibration flow channel and a discharge mechanism. The lifting and feeding mechanism lifts the material and sends it to the straight vibration flow channel. The straight vibration flow channel vibrates and screens the material and directly delivers the material that meets the requirements to the discharge mechanism one by one for feeding; a sensor is provided at the feed port of the discharge mechanism for tracking, counting and speed detection of the material. If the material is unqualified, it is removed by rotating the paddle. If the material is qualified, it is discharged by rotating the paddle.

[0003] Since the straight vibration runner is directly connected to the material discharge mechanism and needs to be transported to the material discharge mechanism one by one during operation, the straight vibration runner needs to stop responding continuously to increase the distance between the front and rear materials. This places high demands on the speed of the straight vibration runner's stopping response. However, the existing single-machine feeding machine without visual lifting often has the phenomenon that the straight vibration runner cannot stop, resulting in confusion and affecting the stable operation of the single machine. In order to brake more stably, users will continuously lower the vibration frequency of the straight vibration runner, but this in turn causes the material transmission speed to be too slow.

[0004] In addition, the patent document with patent application number 2023205907096 discloses a two-in-one sorting device suitable for dual-material unloading. The unloading mechanism of this device is provided with a rotating drive device and a paddle above and below the first unloading channel and the second unloading channel. The upper and lower secondary storage can increase the material unloading speed, and the unloading mechanism is provided with a rejection channel extending on the rear side of the upper paddle, which can reject unqualified materials and improve the qualified rate of materials. However, the unloading mechanism is provided with an arc plate matching the rotation path of the paddle on the front side of the upper paddle. When the material is judged to be unqualified material, the material will fall into the upper paddle, and the upper paddle will rotate backward along the arc plate to pour the material into the rejection channel. At this time, the material can easily get stuck in the gap between the arc plate and the paddle, resulting in the inability to normally reject unqualified materials, affecting the stable operation of the single machine.

[0034] Example 1

[0035] like Figures 1 to 7 The figure shows a fast and stable non-visual lifting and feeding stand-alone machine provided by the utility model, comprising a lifting and feeding mechanism 1, a straight vibration flow channel 2, a transition conveyor belt 3, a discharge mechanism 4, a frame 8 and a silo 9. The lifting and feeding mechanism 1, the straight vibration flow channel 2, the transition conveyor belt 3, the discharge mechanism 4 and the silo 9 are all fixed on the frame 8. The silo wall of the silo 9 is tilted and arranged at the feed port at the bottom of the lifting and feeding mechanism 1. The discharge port at the upper end of the lifting and feeding mechanism 1 is connected to the rear end feed port of the straight vibration flow channel 2, the front end discharge port of the straight vibration flow channel 2 is connected to the transition conveyor belt 3, and the other end of the transition conveyor belt 3 is connected to the feed port at the upper end of the discharge mechanism 4.

[0036] During operation, a large amount of material is poured into the silo 9, and the material enters the feed port at the bottom of the lifting and feeding mechanism 1 along the silo wall, and is lifted to the discharge port at the upper end of the lifting and feeding mechanism 1 by the lifting and feeding mechanism 1, and then falls into the straight vibration flow channel 2, the straight vibration flow channel 2 vibrates and screens the material, and transports the material that meets the size requirements one by one to the transition conveyor belt 3 for transition, and then transports the material to the discharge mechanism 4 for discharge through the transition conveyor belt 3. By arranging the transition conveyor belt 3 between the straight vibration flow channel 2 and the discharge mechanism 4 to increase the distance between the front and rear materials, it is possible to avoid the straight vibration flow channel 2 being unable to stop stably and affecting the stable operation of the single machine, and during operation, there is no need to lower the vibration frequency of the straight vibration flow channel for more stable stopping. The vibration frequency of the straight vibration flow channel 2 can be appropriately increased, and the conveying speed of the transition conveyor belt 3 can be appropriately increased, thereby increasing the material discharge speed of the single machine;

[0037] like Figures 1 to 5The unloading mechanism 4 includes a feeding photoelectric box 41, a unloading channel 42, a first-level paddle 43, a first-level rotating mechanism 44, a second-level paddle 45 and a second-level rotating mechanism 46. The feeding photoelectric box 41 is located at the feeding port of the unloading channel 42; the first-level rotating mechanism 44 is driven and connected to the first-level paddle 43. The first-level rotating mechanism 44 can drive the first-level paddle 43 to rotate forward or backward. The unloading channel 42 is extended to the rear of the first-level paddle 43 and is provided with a clearing bin 51. The first-level paddle 43 rotates backward and is connected to the clearing bin. 51 forms a clearing channel 52, the first-level paddle 43 rotates forward to form a first-level transition channel 53 with the front side of the discharge channel 42; the second-level rotating mechanism 46 is drivingly connected to the second-level paddle 45, and the second-level rotating mechanism 46 can drive the second-level paddle 45 to rotate forward or backward. The discharge channel 42 is extended to the rear of the second-level paddle 45 to be provided with a rejection bin 54. The second-level paddle 45 rotates backward to form a rejection channel 55 with the rejection bin 54, and the second-level paddle 45 rotates forward to communicate with the discharge port of the discharge channel 42;

[0038] Specifically, the single machine has two operating modes, one is the working mode, in which the single machine feeds normally; the other is the cleaning mode, in which the single machine does not feed, but cleans out all the materials in the single machine's hopper through the unloading mechanism 4; when the single machine is in the cleaning mode, it sends a signal to the first-level rotating mechanism 44, and the first-level rotating mechanism 44 then drives the first-level paddle 43 to rotate backward until the central axis of the first-level paddle 43 and the front end slope of the bottom of the cleaning bin 51 are on the same horizontal plane, and the driving stops. At this time, the first-level paddle 43 and the cleaning bin 51 form a cleaning channel 52, as shown in FIG. Figure 3 As shown, the materials of the single machine are cleared out of the single machine one by one along the clearing channel 52. During the entire clearing process, the first-level paddle 43 keeps this position unchanged; when the single machine is in working mode, the first-level rotating mechanism 44 drives the first-level paddle 43 to rotate forward after receiving the signal until the first-level paddle 43 forms a transition sealed space with the front and rear of the discharge channel 42 and stops driving. When the material passes through the feed port of the discharge channel 42, the feed photoelectric box 41 tracks, counts and detects the speed of the material, and then the material enters the transition sealed space for storage. When the quantity, speed, etc. of the material are judged to be not meeting the verification standard value, the controller will send a signal to the second-level rotating mechanism 46, and the second-level rotating mechanism 46 will drive the second-level paddle 45 to rotate backward in advance until the central axis of the second-level paddle 45 is on the same horizontal plane as the front end slope of the bottom of the rejection bin 54 and stops driving. At this time, the second-level paddle 45 and the rejection bin 54 form a rejection channel 55, as shown in FIG. Figure 4As shown, the first-level rotating mechanism 44 then continues to drive the first-level paddle 43 to rotate forward, opening the first-level transition channel 53, and unqualified materials pass through the first-level transition channel 53 and are cleared out of the discharge mechanism 4 along the rejection channel 55; when the material is judged to be qualified material, the second-level rotating mechanism 46 receives the signal and drives the second-level paddle 45 to rotate forward in advance until the second-level paddle 45 and the front and rear of the discharge channel 42 form a material storage sealed space, and then the driving is stopped, and then the first-level rotating mechanism 44 continues to drive the first-level paddle 43 to rotate forward, and qualified materials pass through the first-level transition channel 53 and enter this material storage sealed space for storage, as shown in FIG. Figure 5 As shown, when the storage hopper of the line body reaches below the discharge port of the feeding mechanism 4, the secondary rotating mechanism 46 continues to drive the secondary paddle 45 to rotate forward, and the qualified material falls into the storage hopper, completing the feeding;

[0039] In the working state, by setting the configuration of the first-level transition and the second-level miscellaneous feeding, the second-level paddle 45 is given time to rotate to the miscellaneous feeding position or the storage position before taking over the material. This can avoid the material getting stuck and the paddle getting stuck because the material rotates around after reaching the second-level paddle 45. The material can be mixed and fed normally, thereby ensuring the stable operation of the single machine and improving the feeding speed of the single machine to a certain extent.

[0040] Furthermore, if Figures 3 to 5 As shown, the first-level paddle 43 is a two-material paddle, and the material discharge channel 42 is provided with a first-level limiting plate 61 with a triangular cross-section at the upper and lower ends of the front side of the first-level paddle 43. The top angle of the first-level limiting plate 61 faces the first-level paddle 43, and the side of the upper first-level limiting plate 61 close to the first-level paddle 43 matches the rotation path of the first-level paddle 43. Therefore, when the single machine is in the clearing mode, the first-level paddle 43 rotates until its axis and the front end slope of the clearing bin 51 and the top angle of the upper first-level limiting plate 61 are on the same horizontal plane. At this time, the channel above the first-level paddle 43 and the channel below can be completely separated to avoid excessive clearing. During the feeding process, the material falls into places other than the cleaning channel 52; and the side of the lower first-level limit plate 61 close to the first-level paddle 43 matches the rotation path of the first-level paddle 43. Therefore, when the single machine is in working mode, the first-level paddle 43 rotates to the point where its axis is on the same horizontal plane as the rear side of the discharge channel 42 and the top angle of the lower first-level limit plate 61. At this time, a transitional sealed space can be formed, which can ensure that the material can smoothly enter the angle between the first-level paddle 43 and the lower first-level limit plate 61 to store material and wait to enter the secondary channel. The setting of the two first-level limit plates 61 at the upper and lower ends can ensure the stable operation of the single machine.

[0041] Furthermore, if Figures 3 to 5As shown, the secondary paddle 45 is a two-material dividing paddle, and the unloading channel 42 is provided with a secondary limiting plate 62 with a triangular cross-section at the upper and lower ends on the front side of the secondary paddle 45. The top angle of the secondary limiting plate 62 faces the secondary paddle 45, and the side of the upper and lower secondary limiting plates 62 close to the secondary paddle 45 matches the rotation path of the secondary paddle 45. Similarly, the setting of the upper secondary limiting plate 62 can prevent unqualified materials from falling into places other than the rejection channel 55 during the cleaning process, and the setting of the lower secondary limiting plate 62 can ensure that qualified materials can smoothly enter the angle between the secondary paddle 45 and the lower secondary limiting plate 62 for storage to wait for entering the line storage hopper. The setting of the upper and lower secondary limiting plates 62 can ensure the stable operation of the single machine.

[0042] Furthermore, the first-level limiting plate 61 and the second-level limiting plate 62 are both made of triangular-angle aluminum. The use of triangular-angle aluminum is lightweight and has no burrs on its top corners and surface, which can prevent the paddle from being scratched or stuck during rotation, and can ensure the stable operation of the single machine to a certain extent.

[0043] Furthermore, if Figure 6 As shown, it also includes a touch screen column 7 for fixing the touch screen, and the transition conveyor belt 3 includes two independently set single conveyor belts 31. The two single conveyor belts 31 are symmetrically fixed on the touch screen column 7, and the two single conveyor belts 31 are connected by a connecting piece at the end away from the touch screen column 7. The single conveyor belts 31 on both sides are fixed separately, which is convenient for maintenance and disassembly, and reduces the maintenance cost of a single machine.

[0044] Furthermore, if Figure 6 and Figure 7 As shown, the single conveyor belt 31 includes two side plates 32, a driver 33, a driving wheel structure 34, a driven wheel structure 35 and a belt 36. The two side plates 32 are connected by connecting members 37, and the driven wheel structure 35 and the driving wheel structure 34 are respectively fixed to the front and rear ends of the two side plates 32. The driver 33 is driven and connected to the driving wheel structure 34, and the belt 36 rotates on the periphery of the driving wheel structure 34 and the driven wheel structure 35. When conveying materials, the driver 33 drives the driving wheel structure 34 to rotate, thereby driving the belt 36 and the driven wheel structure 35 to rotate, thereby realizing the conveying of materials. The transition conveyor belt 3 is arranged between the straight vibration flow channel 2 and the unloading mechanism 4 to increase the distance between the front and rear materials, thereby ensuring the stable operation of the single machine and improving the feeding speed of the single machine.

[0045] In addition, guide grooves are provided on the wheels of the driving wheel structure 34 and the driven wheel structure 35, and guide strips matching the guide grooves are provided on the belt 36. During the rotation of the belt 36, the guide strips of the belt 36 always slide in the guide grooves, which can prevent the belt 36 from running off the track and causing damage to the belt edge, thereby ensuring stable operation of the transition conveyor belt 3.

[0046] Furthermore, the front end of the straight vibration channel 2 is the discharge end, which overlaps with the feed end of the transition conveyor belt 3 by at least 10 mm. More specifically, the driving wheel structure 34 is located at the feed end of the transition conveyor belt 3, and the edge of the discharge end of the straight vibration channel 2 exceeds the axis of the driving wheel structure 34, and is at least 10 mm away from the axis of the driving wheel structure 34; and the lowest point of the discharge end of the straight vibration channel 2 needs to be 2 to 5 mm higher than the belt surface of the belt 36. This setting can prevent the material from sliding back when it is transported from the discharge end of the straight vibration channel 2 to the feed end of the transition conveyor belt 3, thereby further improving the stability of the single machine operation.

[0047] Furthermore, if Figures 3 to 5 As shown, the cleaning bin 51 and the rejecting bin 54 are designed as one body, which makes the unloading mechanism 4 more beautiful and saves production costs; an intermediate partition 56 is provided between the two, and the intermediate partition 56 is tilted to guide the material cleaning.

[0048] Example 2

[0049] like Figure 8 As shown, the difference from Example 1 is that the unloading channel 42 is provided with a secondary arc plate 63 on the front side of the secondary paddle 45, and the inner arc of the secondary arc plate 63 matches the rotation path of the secondary paddle 45. The inner side of the secondary arc plate 63 is a circular arc. Compared with the triangular angle aluminum set above and below, the secondary arc plate 63 is more matched with the rotation path of the secondary paddle 45. Because the secondary paddle 45 often needs to be reset during the debugging process, the secondary arc plate 63 can better prevent the material on the secondary paddle 45 from falling out of the unloading mechanism 4 when the secondary paddle 45 is reset.

[0050] In summary, in the present invention, a transition conveyor belt 3 is provided between the straight vibration flow channel 2 and the unloading mechanism 4 to increase the distance between the front and rear materials, thereby preventing the straight vibration flow channel 2 from being unable to stop stably and affecting the stable operation of the single machine, and can speed up the transmission speed of the straight vibration flow channel 2, thereby improving the feeding speed of the single machine; in addition, the unloading mechanism 4 is designed with a first-level transition and a second-level miscellaneous configuration, giving the second-level paddle 45 time to rotate into place in advance, which can avoid the occurrence of material jamming and the inability to remove materials normally, thereby ensuring the stable operation of the single machine.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
