Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece feeding machinery technology, specifically to a stable large material lifting and feeding single machine. Background Technology
[0002] Due to the increasing demand for packaging large materials (W≤8*8mm, L≤20*8mm) such as granules, flakes, capsules, and toy building blocks, more and more large material lifting and feeding machines are appearing on the market. Large material lifting and feeding machines generally include a lifting and feeding mechanism, a vertical vibration channel, a vision inspection mechanism, and a feeding mechanism. During operation, the lifting and feeding mechanism lifts the material and sends it to the vertical vibration channel. The vertical vibration channel vibrates and screens the material and sends the qualified material to the vision inspection mechanism. Then, the vision inspection mechanism sends the material to the feeding mechanism one by one and performs visual inspection on the material during the conveying process. Finally, the material is fed through the feeding mechanism.
[0003] However, the large material lifting and feeding machines currently on the market generally suffer from unstable factors such as material jamming, incomplete material discharge, and material accumulation, which reduce the stability of the operation of the large material lifting and feeding machines and also affect the accuracy of material feeding. Utility Model Content
[0004] To address the existing problems, this utility model proposes a stable single-unit material lifting and feeding machine to avoid unstable factors such as material jamming, incomplete material discharge, and material accumulation, thereby improving the stability and accuracy of single-unit material feeding.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A stable large material lifting and feeding machine includes a frame and a lifting and feeding mechanism, a straight vibration flow channel, a vision inspection mechanism, a feeding mechanism, and a transition conveyor belt fixed on the frame. The lifting and feeding mechanism includes a storage section, a lifting section, and a rear tilting section arranged in sequence. Chain plates are wound around the storage section, the lifting section, and the rear tilting section. Baffles for assisting material lifting are arranged at intervals on the chain plates. A large arc transition is provided between the storage section and the lifting section.
[0007] The straight vibration channel and the lifting and feeding mechanism are set in parallel, and the transition conveyor belt is located at the discharge port of the rear tipping section; the end of the transition conveyor belt is connected to the straight vibration channel, the end of the straight vibration channel is connected to the vision inspection mechanism, and the end of the vision inspection mechanism is connected to the unloading mechanism.
[0008] The feeding mechanism includes a feeding bin and a feeding lever installed in the feeding bin. The feeding lever divides the feeding bin into a discharge channel and a storage channel. The feeding lever rotates in the discharge channel and the storage channel, and the two sides of the feeding lever at one end of the storage channel are tilted towards the middle.
[0009] Preferably, the front section of the storage section is provided with a double-layer return baffle structure, which includes a support shaft, a support plate, an upper soft baffle and a lower soft baffle. The support shaft is fixed to the front section of the storage section, the support plate is elastically fixed to the support shaft, and the upper soft baffle and the lower soft baffle are respectively fixed to the upper and lower sides of the support plate; the lower soft baffle is shorter than the upper soft baffle.
[0010] Preferably, the direct vibration channel includes an interconnected primary transition channel and a secondary screening channel, with the end of the transition conveyor belt connected to the primary transition channel.
[0011] Preferably, a sensor is provided above the middle section of the primary transition channel.
[0012] Preferably, the transition conveyor belt includes a drive wheel, a driven wheel, a driver, and a conveyor belt, with the conveyor belt wound around the drive wheel and the driven wheel, and the driver connected to the drive wheel via a synchronous pulley structure.
[0013] Preferably, the transition conveyor belt is provided with a discharge guide plate on the side near the discharge port of the rear tipping section, the transition conveyor belt is provided with a baffle plate on the other side, and the rear tipping section is provided with an auxiliary guide plate on the inner side of the baffle plate.
[0014] Preferably, the lifting and feeding mechanism also includes left and right side plates, which are folded inward and provided with support guide plates that match the path of the chain plate. The back of the chain plate is provided with a back hook, which is movably engaged on the support guide plates on both sides.
[0015] Compared with the prior art, the present invention has the following advantages:
[0016] In this invention, the material feeding mechanism includes a storage section, a lifting section, and a rear tilting section, all sequentially arranged with chain plates. The chain plates are spaced apart to assist in material lifting. A large arc transition is provided between the storage section and the lifting section, acting as a buffer to prevent large materials from getting stuck between the two partitions and breaking during rapid lifting. A transition conveyor belt is installed between the parallel material feeding mechanism and the straight-vibration flow channel, allowing the material feeding mechanism to directly tilt and tilt, and then the transition conveyor belt to transport the large materials forward, avoiding the problems of material jamming and incomplete dumping that occur during turning and dumping. In the unloading mechanism, a discharge paddle divides the unloading bin into a discharge channel and a storage channel. The discharge paddle rotates in both channels, with its two sides at one end in the storage channel tilted towards the center. When one or more large materials fall onto the discharge paddle, they automatically concentrate towards the center, making the feeding more precise and effectively preventing material jamming due to uncontrollable material direction.

Detailed Implementation
[0029] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] like Figures 1 to 9 The image shows a stable large-material lifting and feeding machine provided by this utility model, including a frame 1 and a lifting and feeding mechanism 2, a vertical vibration flow channel 3, a vision inspection mechanism 4, a feeding mechanism 5, and a transition conveyor belt 6 fixed on the frame 1. Figure 3As shown, the lifting and feeding mechanism 2 includes a storage section 21, a lifting section 22, and a rear tilting section 23 arranged in sequence. The rear tilting section 23 and the storage section 21 are located at the upper and lower ends of the lifting section 22, respectively. A chain plate 24 is wound around the storage section 21, the lifting section 22, and the rear tilting section 23. Baffles 25 for assisting material lifting are spaced apart on the chain plate 24. A large arc 26 is provided between the storage section 21 and the lifting section 22 for transition. The radius of the large arc 26 is at least 480mm to ensure the minimum distance between the two baffles 25 on the chain plate 24. The material size is larger than the maximum material size (W=8*8mm, L=20*8mm). During operation, the material is manually poured into the storage section 21. With the rotation of the chain plate 24 and the support of the partition plate 25, the large material enters the lifting section 22 and is flipped backward in the back-turning and unloading section 23 to complete the unloading. In this process, the large arc 26 between the storage section 21 and the lifting section 22 can play a buffering role in the lifting. Instead of the small arc transition, it can prevent the large material standing between the two partition plates 25 from being broken due to rapid lifting, thus improving the stability of single-machine feeding.
[0033] like Figure 1 and Figure 2 As shown, the straight vibration channel 3 and the lifting and feeding mechanism 2 are arranged in parallel. The rear tilting and dumping section 23 of the lifting and feeding mechanism 2 directly tilts and dumps the material, while the transition conveyor belt 6 is located at the dumping port of the rear tilting and dumping section 23 to receive the large material and drive the large material forward. The lifting and feeding mechanism 2 tilts and dumps the material directly, and then the transition conveyor belt 6 is used to transport the large material forward. This can avoid the problems of material jamming and incomplete dumping that occurred in the past when the material was directly turned and dumped, and improve the stability of single-machine feeding.
[0034] The end of the transition conveyor belt 6 is connected to the straight vibration channel 3, the end of the straight vibration channel 3 is connected to the vision inspection mechanism 4, and the end of the vision inspection mechanism 4 is connected to the unloading mechanism 5. During operation, the straight vibration channel 3 performs size screening and conveying of the material conveyed from the transition conveyor belt 6, ensuring that large materials enter the vision inspection mechanism 4 in a certain direction and in an orderly manner. While conveying the large materials forward, the vision inspection mechanism 4 performs visual inspection on the large materials. The visual inspection results are transmitted to the unloading mechanism 5, and the unloading mechanism 5 sorts the materials entering the unloading bin 51 according to the results.
[0035] like Figure 4As shown, the feeding mechanism 5 includes a feeding bin 51 and a feeding paddle 52 disposed in the feeding bin 51. In this embodiment, the feeding mechanism 5 is a double feeding bin 51, each feeding bin 51 is divided into two levels of feeding, and a feeding paddle 52 is rotatably disposed in each level. The initial state of the feeding paddle 52 is that it is vertically disposed in the feeding bin 51. The feeding paddle 52 divides each level of the feeding bin 51 into a discharge channel and a storage channel. When the feeding paddle 52 rotates forward, the discharge channel is opened. When the feeding paddle 52 rotates backward, the feeding paddle 52 and the front side wall of the feeding bin 51 form a storage channel. The upper discharge channel of each feeding bin 51 is used to remove all materials, and the lower discharge channel is used to remove impurities. Both the upper and lower storage channels of each feeding bin 51 are used to store materials. During cleaning, the upper feeding paddle 52 rotates forward to open the discharge channel to discharge all materials. Figure 4 As shown, during feeding, the upper feeding plate 52 rotates backward to form an upper storage channel. The material conveyed by the vision inspection mechanism 4 will first fall into the upper storage channel for storage. Then, the feeding mechanism 5 controls the lower feeding plate 52 to rotate according to the detection result of the vision inspection mechanism 4. When the detection result is unqualified, the lower feeding plate 52 will rotate forward, and the material will be discharged outward along the discharge channel. If the detection result is qualified, the lower feeding plate 52 will rotate backward to form a lower storage channel. When the storage hopper appears at the discharge port of the feeding bin 51, the lower feeding plate 52 will rotate in the opposite direction to open the lower storage channel, and the material will then enter the storage hopper to complete the feeding.
[0036] like Figure 5 As shown, the feeding paddle 52 is rotated in the storage channel with both sides tilted towards the center. Therefore, when a large piece of material falls onto the feeding paddle 52, it will automatically concentrate towards the center, making the feeding more accurate. It also avoids the phenomenon that two or more large pieces of material would collide and get stuck in the feeding bin 51 due to the inability to control the direction of the large pieces, thus improving the stability and accuracy of single-machine feeding. Preferably, the other end of the feeding paddle 52 is also designed to be tilted towards the center on both sides, so that no matter how it rotates, the feeding paddle 52 at one end of the storage channel is always designed to be tilted towards the center on both sides.
[0037] Furthermore, such as Figure 3 and Figure 6As shown, the front section of the storage section 21 is provided with a double-layer return baffle structure 27. The double-layer return baffle structure 27 includes a support shaft 271, a support plate 272, an upper soft baffle 273, and a lower soft baffle 274. The support shaft 271 is fixed to the front section of the storage section 21, the support plate 272 is elastically fixed to the support shaft 271, and the upper soft baffle 273 and the lower soft baffle 274 are respectively fixed to the upper and lower sides of the support plate 272. The ends of the upper soft baffle 273 and the lower soft baffle 274 droop downwards. On the chain plate 24, the lower soft baffle 274 is shorter than the upper soft baffle 273. When the chain plate 24 is lifted upward, the partition 25 will lift the lower soft baffle 274 and the upper soft baffle 273 in sequence. During this process, a small amount of material may slip back from the gap between the edge of the partition 25 and the edge of the chain plate 24. At the same time, because the lower soft baffle 274 is shorter, it will fall back first to block this part of the material. The double-layer baffle completely avoids the material slipping back and improves the stability of single-machine feeding.
[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the direct vibration channel 3 includes a primary transition channel 31 and a secondary screening channel 32 that are interconnected. The end of the transition conveyor belt 6 is connected to the primary transition channel 31. The primary transition channel 31 serves as a transition channel to prevent excessive accumulation of large materials from affecting subsequent feeding. Furthermore, the cross-section of the primary transition channel 31 is wavy, and under the vibration of the direct vibration device, the material will be concentrated at each concave point of the channel and conveyed forward. The secondary screening channel 32 can perform size screening of large materials, ensuring that large materials enter the vision inspection mechanism 4 in a certain direction and in an orderly manner.
[0039] Furthermore, a sensor 7 is installed above the middle section of the primary transition channel 31. The sensor 7 can sense the material. When no material is sensed passing by, it will transmit a signal to the main controller. The main controller will control the transition conveyor belt 6 to feed the material. If material is sensed passing by, the main controller will control the transition conveyor belt 6 to temporarily stop feeding the material, which can prevent the material from accumulating and affecting subsequent processes.
[0040] Furthermore, such as Figure 7 As shown, the transition conveyor belt 6 includes a drive wheel 61, a driven wheel 62, a driver 63, and a conveyor belt 64. The conveyor belt 64 is wound around the drive wheel 61 and the driven wheel 62. The driver 63 is connected to the drive wheel 61 through a synchronous wheel structure. Therefore, the driver 63 can drive the drive wheel 61 to rotate through the synchronous wheel structure, thereby driving the conveyor belt 64 and the driven wheel 62 to rotate, thus realizing the conveying of materials.
[0041] Furthermore, such as Figure 8As shown, a material guide plate 65 is provided on one side of the transition conveyor belt 6 near the discharge port of the rear tipping section 23, and a baffle plate 66 is provided on the other side of the transition conveyor belt 6. An auxiliary guide plate 231 is provided inside the baffle plate 66 in the rear tipping section 23. The setting of the material guide plate 65 and the auxiliary guide plate 231 can both assist the large material to fall onto the transition conveyor belt 6, while the baffle plate 66 can prevent the material from tipping over and falling outside the machine.
[0042] Furthermore, such as Figure 9 As shown, the lifting and feeding mechanism 2 also includes left and right side plates 28. The left and right side plates 28 are folded inward and have support guide plates 29 that match the path of the chain plate 24. The back of the chain plate 24 is provided with a back hook 241, which is movably locked on the support guide plates 29 on both sides. The support guide plates 29 can support the chain plate 24 and prevent the feeding machine from failing to operate due to the chain plate 24 collapsing during rotation.
[0043] In summary, in this utility model, the storage section 21, the lifting section 22, and the rear tilting section 23 of the lifting and feeding mechanism 2 are sequentially arranged with chain plates 24. The chain plates 24 are spaced with partitions 25 to assist in material lifting. A large arc 26 is provided between the storage section 21 and the lifting section 22 for transition, which acts as a buffer to prevent large materials from getting stuck between the two partitions 25 and breaking during rapid lifting. A transition conveyor belt 6 is provided between the parallel lifting and feeding mechanism 2 and the straight vibration channel 3, allowing the lifting and feeding mechanism 2 to directly tilt and tilt the material, and then the transition conveyor belt 6 helps to lift large materials. Forward material conveying avoids the problems of material jamming and incomplete material discharge that occur when directly turning and dumping material. In the feeding mechanism 5, the feeding paddle 52 divides the feeding bin 51 into a discharge channel and a storage channel. The feeding paddle 52 rotates in the two channels, and the two sides of the feeding paddle 52 at one end of the storage channel are tilted towards the center. When one or more large pieces of material fall onto the feeding paddle 52, the large pieces of material will automatically concentrate towards the center, making the feeding more accurate and effectively avoiding the phenomenon of material jamming caused by the inability to control the direction of large pieces of material. All three points can improve the stability and accuracy of the feeding machine.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
