Description

Technical Field

[0001] This utility model relates to the field of workpiece feeding machinery technology, specifically to a single machine for lifting and feeding ultra-large materials through a dual-channel system. Background Technology

[0002] As the demand for packaging materials such as granules, flakes, capsules, and toy building blocks gradually increases, more and more lifting feeding machines are appearing on the market. Lifting feeding machines generally include a lifting feeding mechanism, a vertical vibration channel, a transition conveyor belt, and a feeding mechanism. During operation, the lifting feeding mechanism lifts the material to the vertical vibration channel, which vibrates and screens the material and conveys the qualified material to the transition conveyor belt. Then, the transition conveyor belt conveys the material one by one to the feeding mechanism, and finally the feeding mechanism supplies the material.

[0003] However, in the current market, dual-channel lifting feeding machines are generally only suitable for feeding small and medium-sized materials with both length and width less than 15 points (15*8mm). For extra-large materials with either length or width greater than 15 points (15*8mm), manual feeding is basically required, which greatly reduces the feeding speed and is very likely to result in misfeeding and missed feeding.

[0004] Therefore, patent document with patent application number 2025208716634 discloses a single machine for lifting and feeding large materials, which replaces manual labor with machines. In this patent, the single machine for lifting and feeding large materials has a double-channel and double-direct-vibration flow channel, while the transition conveyor belt is a single channel. Each flow channel is connected to the single-channel transition conveyor belt, and a feeding sensor is set at this connection point, which can make the two flow channels feed alternately to improve the material conveying speed. However, the two flow channels will resonate due to the direct vibration underneath, making it impossible for the material on the flow channel to stop stably. This results in inaccurate control of alternating feeding, causing overfeeding and greatly reducing the accuracy of feeding. In addition, the unloading device is a single channel, and its feeding speed is limited. Utility Model Content

[0005] To address the existing problems, this utility model proposes a dual-channel lifting and feeding machine for oversized materials, which is suitable for lifting, feeding, and supplying oversized materials, thereby improving the feeding speed and accuracy of oversized materials.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A single-channel lifting and feeding machine for ultra-large materials includes a frame, a lifting and feeding mechanism, a primary transition direct vibration channel, a secondary direct vibration channel, a transition conveyor belt, a primary unloading mechanism, and a secondary storage mechanism. The lifting and feeding mechanism is inclined on the frame with an inclination angle ranging from 60° to 70°. The top discharge port of the lifting and feeding mechanism is positioned rearward and connects to the primary transition direct vibration channel located on the side via a turning discharge hopper. The secondary direct vibration channel, the transition conveyor belt, and the primary unloading mechanism are all dual-channel, and their channels are sequentially connected one-to-one. Each channel of the primary transition direct vibration channel is connected to every channel of the secondary direct vibration channel.

[0008] The primary feeding mechanism includes a dual-channel feeding chamber and feeding opening and closing mechanisms and a waste removal opening and closing mechanism located in both channels of the feeding chamber. The opening and closing fulcrums of the feeding opening and closing mechanism and the waste removal opening and closing mechanism are respectively located near the front inner side and the rear inner side of the feeding chamber. A rejection bin is connected to the waste removal opening and closing mechanism on the rear side of the feeding chamber. The two feeding opening and closing mechanisms converge below and connect to the secondary storage mechanism.

The storage drive mechanism is driven and connected to the motor synchronous pulley. The driven synchronous pulley is connected to the left opening / closing lever, the steering synchronous pulley is connected to the right opening / closing lever, and the tension pulley is located below the steering synchronous pulley.

[0011] Preferably, a limiting plate is provided at the end of the left opening / closing lever that is away from the rotating end.

[0012] Preferably, the hopper is inclined and directly installed towards the side of the primary transition straight vibration channel.

[0013] Preferably, the primary transition direct vibration channel is provided with multiple V-shaped and interconnected guide feed troughs.

[0014] Preferably, both the feeding opening and closing mechanism and the waste removal opening and closing mechanism include a feeding drive mechanism, a rotating shaft, and a feeding opening and closing lever. The feeding drive mechanism is driven and connected to the rotating shaft, and the feeding opening and closing lever is fixed on the rotating shaft. In the feeding opening and closing mechanism, the rotating shaft is located near the front inner side of the feeding cavity, and the feeding opening and closing lever is driven by the feeding drive mechanism to open or close the feeding cavity. In the waste removal opening and closing mechanism, the rotating shaft is located near the rear inner side of the feeding cavity, and the feeding opening and closing lever is driven by the feeding drive mechanism to open or close the rejection bin.

[0015] Preferably, the feeding chamber is provided with an air blowing pipe above the feeding opening and closing lever.

[0016] Preferably, the secondary direct vibration channel includes an upper guide channel and a lower screening channel, which are arranged in a stepped manner.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] In this invention, the tilt angle of the lifting and feeding mechanism on the frame ranges from 60° to 70°. The top discharge point of the lifting and feeding mechanism is positioned rearward and connects to the first-stage transition direct vibration channel located on the side via a turning hopper. Furthermore, the opening and closing fulcrums of the discharge opening and closing mechanism and the waste removal opening and closing mechanism are located on the front and rear inner sides of the discharge cavity, respectively. Compared to a rotary opening and closing structure with its fulcrum located in the middle of the discharge cavity, this design provides a larger storage, feeding, and waste removal space. Therefore, this invention is suitable for lifting and feeding ultra-large materials. Material feeding; in addition, a primary transitional direct vibration channel is set in front of the secondary direct vibration channel. Through the two channels, oversized materials can be transported one by one to the transitional conveyor belt in an orderly manner. In addition, the secondary direct vibration channel, the transitional conveyor belt and the primary feeding mechanism are all dual-channel, and the three channels are connected one-to-one in sequence, which can avoid mutual interference between the two channels, thereby improving the accuracy of material feeding. Furthermore, the dual-channel setting, and the convergence of the two channel feeding opening and closing mechanisms below and the connection with the secondary storage mechanism, can greatly improve the feeding speed of oversized materials.

[0033] 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.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0035] 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.

[0036] like Figures 1 to 11 The image shows a dual-channel lifting and feeding machine for oversized materials provided by this utility model. It includes a frame 1, a lifting and feeding mechanism 2, a primary transition direct vibration channel 3, a secondary direct vibration channel 4, a transition conveyor belt 5, a primary unloading mechanism 6, and a secondary storage mechanism 7. The lifting and feeding mechanism 2 is inclined on the frame 1 with an inclination angle ranging from 60° to 70°. This design can effectively reduce the occurrence of oversized materials falling off the lifting chain plate during the lifting and feeding process, and is suitable for lifting and feeding oversized materials.

[0037] like Figures 1 to 4 As shown, the first-stage transition straight vibration channel 3 is set on one side of the lifting and feeding mechanism 2. The top discharge port of the lifting and feeding mechanism 2 is set backward and connected to the first-stage transition straight vibration channel 3 on the side through the discharge hopper 8. Compared with the non-visual lifting and feeding single machine disclosed in patent number 2024229078126, in which the top of the lifting and feeding mechanism 2 is connected to the straight vibration channel through the discharge port, the discharge hopper 8 of the lifting and feeding mechanism 2 of this utility model is set backward. This can avoid the phenomenon of large materials getting stuck due to the gap between the discharge hopper 8 set on the front side and the straight vibration channel. This design is suitable for feeding large materials.

[0038] like Figure 1 and Figure 2As shown, the secondary vertical vibration channel 4, the transition conveyor belt 5, and the primary feeding mechanism 6 are all dual-channel systems. The primary transition vertical vibration channel 3 is connected to each channel of the secondary vertical vibration channel 4. The primary transition vertical vibration channel 3 between the secondary vertical vibration channel 4 and the feeding hopper 8 serves as a transition, preventing excessive accumulation of oversized materials and affecting subsequent feeding. The channels of the secondary vertical vibration channel 4, the transition conveyor belt 5, and the primary feeding mechanism 6 are connected sequentially and one-to-one. That is, one channel of the secondary vertical vibration channel 4 is connected to one channel of the transition conveyor belt 5 on the same side, and this channel of the transition conveyor belt 5 is connected to one channel of the primary feeding mechanism 6 on the same side. The other channel is connected sequentially and one-to-one, forming a two-independent feeding mode, replacing the alternating feeding mode disclosed in patent number 2025208716634. Therefore, it effectively avoids mutual interference between the two channels and greatly improves the accuracy of feeding. Furthermore, the dual-channel setup enables two independent feeding channels, doubling the transmission efficiency of oversized materials and thus greatly increasing the feeding speed of oversized materials.

[0039] like Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, the primary feeding mechanism 6 includes a dual-channel feeding chamber 61 and feeding opening and closing mechanisms 62 and sludge removal opening and closing mechanisms 63, both located in the two channels of the feeding chamber 61. A sensor is provided at the inlet of the feeding chamber 61. The opening and closing fulcrums of the feeding opening and closing mechanism 62 and the sludge removal opening and closing mechanism 63 are respectively located near the front inner side and the rear inner side of the feeding chamber 61. A rejection chamber 9 is connected to the rear sludge removal opening and closing mechanism 63 of the feeding chamber 61. Specifically, both the feeding opening and closing mechanism 62 and the sludge removal opening and closing mechanism 63 include a feeding drive mechanism 64 and a rotating shaft. The feeding opening and closing lever 65 and the feeding drive mechanism 64 are all driven and connected to the rotating shaft 65, and the feeding opening and closing lever 66 is fixed on the rotating shaft 65. In the feeding opening and closing mechanism 62, the rotating shaft 65 is located near the front inner side of the feeding cavity 61, and the feeding opening and closing lever 66 is driven by the feeding drive mechanism 64 to open or close the feeding cavity 61. In the impurity removal opening and closing mechanism 63, the rotating shaft 65 is located near the rear inner side of the feeding cavity 61, and the feeding opening and closing lever 66 is driven by the feeding drive mechanism 64 to open or close the rejection chamber 9. Figure 7 As shown, when the feeding opening and closing levers 66 of both the feeding opening and closing mechanism 62 and the waste removal opening and closing mechanism 63 are in the closed state, the feeding opening and closing levers 66 of both form a primary storage space in the feeding cavity 61, such as... Figure 9 As shown, when the feeding opening and closing lever 66 of the feeding opening and closing mechanism 62 is opened under the drive, the feeding cavity 61 is converted into a primary feeding space, as... Figure 8As shown, when the feeding opening and closing lever 66 of the feeding opening and closing mechanism 62 is closed, and the feeding opening and closing lever 66 of the impurity removal opening and closing mechanism 63 is open, the feeding cavity 61 and the rejection chamber 9 form an impurity removal space. Compared with the rotary opening and closing structure with the fulcrum located in the middle of the feeding cavity 61, this doubles the storage, feeding and impurity removal space, effectively increasing the storage, impurity removal and feeding space. It is suitable for storing, feeding and removing impurities from oversized materials, avoiding the phenomenon of oversized materials getting stuck. In addition, in this utility model, the rejection chamber 9 is located on the rear side of the feeding cavity 61. Compared with the rejection port disclosed in patent number 2025208716634 being located on one side, this optimizes the overall space and is more visually appealing.

[0040] like Figure 5 and Figure 10 As shown, the two-channel feeding opening and closing mechanism 62 converges below and connects to the secondary storage mechanism 7. Specifically, as... Figure 6 As shown, the secondary storage mechanism 7 includes a storage drive mechanism 71, a left opening / closing lever 72, a right opening / closing lever 73, a synchronous belt 74, a motor synchronous pulley 75, a driven synchronous pulley 76, a steering synchronous pulley 77, and a tension pulley 78. The synchronous belt 74 is sequentially wound around the motor synchronous pulley 75, the driven synchronous pulley 76, the steering synchronous pulley 77, and the tension pulley 78. The storage drive mechanism 71 is driven by the motor synchronous pulley 75, the driven synchronous pulley 76 is connected to the left opening / closing lever 72, the steering synchronous pulley 77 is connected to the right opening / closing lever 73, and the tension pulley 78 is located below the steering synchronous pulley 77. This serves as a tension adjustment mechanism. When the storage drive mechanism 71 drives the synchronous pulley 75 of the motor to rotate, the synchronous belt 74 drives the driven synchronous pulley 76, the steering synchronous pulley 77, and the tensioning pulley 78 to rotate, thereby causing the left opening / closing lever 72 and the right opening / closing lever 73 to rotate in opposite directions or relative to each other. After rotating in the opposite direction to a specified angle, a secondary feeding space is formed between the left opening / closing lever 72 and the right opening / closing lever 73. When rotating relative to each other until the left opening / closing lever 72 and the right opening / closing lever 73 come into contact, a secondary storage space is formed between them, and this state is the initial state of the secondary storage mechanism 7. Figure 10 As shown; by setting up a secondary storage mechanism 7, the oversized material in the primary storage space can first fall to the secondary storage space for storage, and then the primary storage space can store the next oversized material, reducing the waiting time between oversized materials and thus improving the feeding speed of oversized materials.

[0041] In actual operation, the lifting feeding mechanism 2 lifts the oversized material to the top, and then conveys it through the rear discharge hopper 8 to the primary transition direct vibration channel 3. The primary transition direct vibration channel 3 disperses the oversized material to the dual channels of the secondary direct vibration channel 4. After that, the oversized material enters the independent channel feeding mode. Under the vibration of the direct vibrator, the material in the two channels of the secondary direct vibration channel 4 enters the corresponding channel of the transition conveyor belt 5 respectively. On the transition conveyor belt 5, the dual cameras above will detect, identify and analyze the image information of the oversized material in the corresponding channel. Then, the oversized material enters the corresponding channel of the discharge cavity 61 and falls into the primary storage space formed by the discharge opening and closing lever 66 and the discharge cavity 61. When passing through the feed inlet of the discharge cavity 61, the sensor will count the oversized material. When the oversized material is determined by the camera to be unqualified material, the discharge drive mechanism 64 of the impurity discharge opening and closing mechanism 63 will drive the rotating shaft. 65 drives the feeding opening and closing lever 66 to rotate backward, so that the feeding cavity 61 is connected to the rejection bin 9. Then, the oversized material is discharged from the single machine through the rejection bin 9. When the oversized material is analyzed and determined to be qualified material by the camera, and the sensor detects that the number of oversized materials passing by has reached the preset number, the feeding drive mechanism 64 of the feeding opening and closing mechanism 62 drives the rotating shaft 65 to drive the feeding opening and closing lever 66 to rotate forward. At this time, the oversized material falls into the secondary storage space for storage. When the storage hopper on the production line reaches the lower part of the secondary storage space of this feeding single machine, the storage drive mechanism 71 will drive the motor synchronous wheel 75 to rotate, so as to drive the left opening and closing lever 72 and the right opening and closing lever 73 to rotate in opposite directions, thereby opening the secondary storage space and the oversized material falls into the storage hopper, completing the feeding. While waiting for the storage hopper, the next group of oversized material will first enter the primary storage space for storage. After the feeding is completed, the secondary storage mechanism 7 returns to the initial storage state.

[0042] Furthermore, such as Figure 3 As shown, the top unloading point of the lifting feeding mechanism 2 is set in an R-shape. Compared with the previous semi-circular unloading point, its unloading arc is increased. At the lowest point of unloading, the lifting belt chain plate is close to vertical, so that the unloading is complete. On the one hand, it can avoid the oversized material from falling outside the machine as the chain plate continues to rotate due to incomplete unloading. On the other hand, it can ensure sufficient material supply and avoid the problem of insufficient oversized material being conveyed forward, which would affect the material supply speed, thus enabling efficient material supply production.

[0043] Furthermore, such as Figure 10 and Figure 11 As shown, a limiting plate 721 is provided at the end of the left opening and closing lever 72 away from the rotating end. When the left opening and closing lever 72 and the right opening and closing lever 73 rotate relative to each other to restore the initial storage state, the limiting plate 721 continuously approaches the right opening and closing lever 73. Finally, the limiting plate 721 completely abuts against the right opening and closing lever 73. At this time, the left opening and closing lever 72 and the right opening and closing lever 73 stop rotating, and the formed secondary storage space is completely sealed.

[0044] Furthermore, such as Figure 4 As shown, the hopper 8 is inclined and directly set towards the first-stage transition vertical vibration channel 3 on the side. This setting, compared to the top feeding bin of the lifting feeding device disclosed in patent number 2025208716634 which is set to rotate at the discharge port, can effectively prevent the hopper 8 from getting stuck at the discharge port. In addition, the discharge port of the hopper 8 is set towards the first-stage transition vertical vibration channel 3, and the discharge port does not exceed the first-stage transition vertical vibration channel 3. Furthermore, the front end of the first-stage transition vertical vibration channel 3 is provided with a guide ramp 31, which prevents oversized materials from falling outside the machine and also effectively assists in the forward conveying of oversized materials.

[0045] Furthermore, such as Figure 4 As shown, the primary transition direct vibration channel 3 is provided with multiple V-shaped and interconnected guide feeding grooves 32. This design can avoid serious stacking of oversized materials, making the feeding smoother.

[0046] Furthermore, such as Figures 7 to 9 As shown, an air blowing pipe 67 is provided above the feeding opening and closing lever 66 of the feeding opening and closing mechanism 62. The air blowing pipe 67 is connected to an air blowing valve. Air outlet holes are evenly provided on the air blowing pipe 67, which can help blow oversized materials to the connection point of the feeding opening and closing lever 66, making subsequent impurity removal or material supply faster and smoother.

[0047] Furthermore, such as Figure 1 and Figure 2 As shown, the secondary direct vibration channel 4 includes an upper guide channel 41 and a lower screening channel 42. The upper guide channel 41 serves as a guide and can collect oversized materials and transport them forward. The upper guide channel 41 and the lower screening channel 42 are arranged in a stepped manner, and the lower screening channel 42 is equipped with a screening port, which can screen and disperse oversized materials, ensuring that oversized materials are transported forward in an orderly manner, and improving the accuracy of oversized material feeding to a certain extent.

[0048] In summary, in this invention, the tilt angle of the lifting and feeding mechanism 2 on the frame 1 ranges from 60° to 70°. The top discharge point of the lifting and feeding mechanism 2 is positioned rearward and connects to the first-stage transition direct vibration channel 3 located on the side via a turning point through the discharge hopper 8. Furthermore, the opening and closing fulcrums of the discharge opening and closing mechanism 62 and the impurity removal opening and closing mechanism 63 are located on the front and rear inner sides of the discharge cavity 61, respectively. Compared to a rotary opening and closing structure with its fulcrum located in the middle of the discharge cavity 61, this design provides a larger storage, feeding, and impurity removal space. Therefore, this invention is suitable for lifting extremely large materials. The feeding, conveying, and supplying mechanisms are implemented. Additionally, a primary transitional primary vibration channel 3 is installed in front of the secondary vibration channel 4. These two channels allow for the orderly, sequential transport of oversized materials to the transitional conveyor belt 5. Furthermore, the secondary vibration channel 4, the transitional conveyor belt 5, and the primary unloading mechanism 6 are all dual-channel systems, connected sequentially to avoid mutual interference between the two channels, thus improving the accuracy of material supply. Moreover, the dual-channel setup, along with the lower convergence of the two unloading opening and closing mechanisms 62 and their connection to the secondary storage mechanism 7, significantly increases the feeding speed of oversized materials.

[0049] 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.
