Abstract
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. 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 device, a vertical vibration channel, a transition conveyor belt, and a feeding device. During operation, the lifting feeding device 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 device, and finally the feeding device supplies the material.
[0003] However, in the current market, most lifting and feeding machines are only suitable for feeding small and medium-sized materials with a length and width of less than 15 points (15*8mm). They are not suitable for feeding oversized materials with either a length or width greater than 15 points (15*8mm). On the one hand, the material is not easy to be lifted and fed by the chain plate when the lifting and feeding device is running, and the material is easy to fall back into the storage bin during the lifting process. On the other hand, the discharge port and discharge chamber of the discharge device do not meet the size of the oversized material, which can easily cause jamming. Utility Model Content

The feeding counting box is located at the top of the feeding cavity. The upper opening and closing structure and the lower opening and closing structure are respectively located at the upper and lower positions inside the feeding cavity, and their opening and closing fulcrum is located on one side inside the feeding cavity. The feeding cavity has a rejection port on one side of the upper opening and closing structure, and a waste removal structure is provided at the rejection port to connect or separate the upper opening and closing structure from the rejection bin.

The limiting plate includes a fixed side and a limiting side connected together. The fixed side is fixed to one end of the opening and closing inclined plate, and the connection angle between the fixed side and the limiting side matches the tilt angle of the opening and closing inclined plate when closing the feeding cavity.
[0011] Preferably, the impurity removal structure includes an impurity removal driver, an impurity removal shaft, and an impurity removal lever. The impurity removal driver is driven to the impurity removal shaft, and the impurity removal lever is fixed on the impurity removal shaft. The impurity removal lever rotates in the rejection port to open or close the rejection port.
[0012] Preferably, the lifting and feeding device includes a storage section, a lifting section and a discharge section. The discharge section is located above the lifting section, the storage section is inclined at an obtuse angle below the lifting section, and a return soft baffle is provided above the storage section.
[0013] Preferably, the direct vibration channel is a dual channel, and a feeding sensor is installed at the connection between each channel and the transition conveyor belt.
[0014] Preferably, each channel of the direct vibration channel includes a direct vibrator, a primary channel, and a secondary channel. The primary and secondary channels are inclinedly arranged on the direct vibrator, and the connection between the primary and secondary channels forms a stepped design. The material distribution guide is located on the primary channel, and the screening port is located on the secondary channel.
[0015] Preferably, side guide plates are provided on both sides of the transition conveyor belt, the size of the opening formed at the end of the side guide plates matches the width of the dual flow channels, and the size of the opening formed at the front end of the side guide plates matches the width of the feed inlet of the discharge cavity.
[0016] Compared with the prior art, the present invention has the following advantages:

Furthermore, the internal opening and closing mechanism of the discharge chamber is equipped with an upper opening and a lower opening and closing structure. The opening and closing fulcrum of the upper and lower opening and closing structures is located on one side of the discharge chamber.

All three of these features improve the stability of the oversized material lifting and feeding unit's operation. Attached Figure Description

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.
[0032] 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.
[0033] like Figures 1 to 6 The image shows a single-unit lifting and feeding machine for large materials provided by this utility model. It includes a frame 1 and a lifting and feeding device 2, a vertical vibration channel 3, a transition conveyor belt 4, and a discharge device 5, all fixed to the frame 1. The lifting and feeding device 2 is inclined on the frame 1, with an inclination angle ranging from 60° to 70°, meaning the angle between the lifting and feeding device 2 and the frame 1 is between 60° and 70°. In this embodiment, as shown... Figure 3As shown, the tilt angle of the lifting and feeding device 2 is set to 65°. Since a lifting conveyor chain plate is movably wound around the lifting and feeding device 2, and storage plates 25 are spaced apart on the lifting conveyor chain plate, during operation, oversized materials are lifted upwards along with the lifting conveyor chain plate via the storage plates 25. Through the cooperation of these two components, the occurrence of oversized materials falling from the storage plates 25 during the lifting and feeding process can be effectively reduced. This method is suitable for lifting and feeding oversized materials, thereby improving the stability of the single-unit operation of the oversized material lifting and feeding machine.
[0034] like Figure 2 As shown, the top of the lifting and feeding device 2 is provided with a feeding bin 21. The outlet of the feeding bin 21 is connected to the direct vibration channel 3. During operation, oversized materials are lifted to the top by the lifting conveyor chain plate and enter the direct vibration channel 3 through the feeding bin 21.
[0035] like Figure 4 As shown, the front end of the vertical vibration channel 3 is provided with a material distribution guide 31. Specifically, the material distribution guide 31 and the upper surface of the vertical vibration channel 3 form a step. After oversized materials fall from the feeding bin 21 into the vertical vibration channel 3, due to the vibration principle, multiple oversized materials will move forward along this step. Due to the height difference formed by the step, multiple materials gradually disperse. Therefore, the material distribution guide 31 plays a role in material distribution. The vertical vibration channel 3 is provided with a screening port 32 on one side near the end, and an air blowing component is provided in the screening port 32. The vertical vibration channel 3 extends a return guide plate 37 at the screening port 32, and the material can fall back from the screening port 32 along the return guide plate 37 to the lifting feeder. On the storage section 22 at the bottom of device 2; during operation, due to the vibration principle, some materials will move forward through the screening port 32, while some materials will fall back onto the storage section 22 through the screening port 32 to be lifted and fed again. Therefore, the screening port 32 can play the role of screening to disperse materials, which can avoid the disorder of the amount of materials conveyed forward due to material accumulation and affect the subsequent feeding. Therefore, the setting of the material distribution guide bar 31 and the screening port 32 can ensure the normal feeding of the oversized material lifting and feeding machine, and improve the stability of the operation of the oversized material lifting and feeding machine. On the other hand, the setting of the screening port 32 can ensure that the materials enter the next operation in a basically uniform direction, that is, vertical or horizontal.
[0036] The end of the straight vibration channel 3 is connected to the transition conveyor belt 4; the other end of the transition conveyor belt 4 is connected to the feed inlet of the feeding device 5. The transition conveyor belt 4 can widen the gap between the front and rear materials, so as to avoid the straight vibration channel 3 from being unable to stop stably and affecting the subsequent feeding. During operation, the oversized materials that pass through the screening port 32 and move forward will enter the feeding device 5 one by one through the transition conveyor belt 4.
[0037] like Figure 5 and Figure 6As shown, the feeding device 5 includes a feeding counting box 51, a feeding cavity 52, an upper opening and closing structure 53, a lower opening and closing structure 54, and a rejection bin 55. The feeding counting box 51 is located at the top of the feeding cavity 52. The feeding counting box 51 has an opening, which is the feeding port of the feeding device 5. The feeding counting box 51 is equipped with a counting sensor at this feeding port to count the material entering the feeding device 5.
[0038] The upper opening and closing structure 53 and the lower opening and closing structure 54 are respectively positioned at the upper and lower levels inside the feeding cavity 52. Specifically, both the upper opening and closing structure 53 and the lower opening and closing structure 54 include an opening and closing inclined plate 61, an opening and closing rotating shaft 63, and an opening and closing driver 62. The opening and closing driver 62 is fixed to the outer wall of the feeding cavity 52. The left side wall of the feeding cavity 52 is divided into three sections: upper, middle, and lower. The opening and closing rotating shaft 63 passes horizontally between the upper and middle sections or between the middle and lower sections of the left side wall of the feeding cavity 52. The opening and closing driver 62 is connected to the opening and closing rotating shaft 63. The opening and closing inclined plate 61 is inclinedly positioned inside the feeding cavity 52 and is fixed to the opening and closing rotating shaft 63 by a fixing plate. Therefore, the upper and lower opening and closing structures are connected at the upper and lower levels. The opening and closing driver 62 can drive the upper and lower opening and closing ramps 61 to rotate to open or close the upper and lower positions inside the feeding cavity 52. When open, oversized materials can be placed down. When closed, the upper and lower opening and closing ramps 61 can form an upper storage space and a lower storage space with the feeding cavity 52, respectively. Since the opening and closing pivot 63, i.e. the opening and closing fulcrum, is located on the left side wall of the feeding cavity 52, compared with other utility models that set a rotating paddle structure in the middle of the feeding cavity 52, its storage space and feeding space are doubled. It is suitable for storing and feeding oversized materials, which can effectively avoid the phenomenon of oversized materials getting stuck, thereby improving the stability of the single machine operation of the oversized material feeding system.
[0039] The feeding chamber 52 has a rejection port 56 on one side of the upper opening and closing structure 53. The rejection port 56 is provided with a waste removal structure 57. Specifically, the waste removal structure 57 includes a waste removal driver 65, a waste removal rotating shaft 66 and a waste removal lever 67. The waste removal driver 65 is driven to the waste removal rotating shaft 66, and the waste removal lever 67 is fixed on the waste removal rotating shaft 66. Therefore, the waste removal driver 65 can drive the waste removal lever 67 to rotate in the rejection port 56 to open or close the rejection port 56, so that the storage space can be connected to or separated from the rejection chamber 55.
[0040] In actual operation, initially, the upper and lower opening and closing ramps 61 are respectively in the closed position inside the feeding cavity 52, forming an upper storage space and a lower storage space with the feeding cavity 52. Oversized materials enter the upper storage space from the feed inlet of the feeding device 5. At the same time, the feed counting box 51 at the top of the feeding cavity 52 counts the oversized materials. If the number of oversized materials detected is inconsistent with the preset number, a signal is transmitted to the impurity removal driver 65. The impurity removal driver 65 immediately drives the impurity removal lever 67 to rotate to open the rejection port 56. At this time, the oversized material enters the rejection bin 55 along the upper opening and closing ramp 61 to complete the removal of impurities. If the number of oversized materials detected is consistent with the preset number, a signal is transmitted to the opening and closing driver 62. The upper opening and closing driver 62 drives the upper opening and closing ramp 61 to rotate downward to open the upper storage space. The oversized material then falls into the lower storage space for storage. When the storage hopper of the circulation line reaches the discharge port of the discharge chamber 52, the lower opening and closing driver 62 drives the lower opening and closing ramp 61 to rotate downward to open the lower storage space. The oversized material then falls into the storage hopper to complete the feeding.
[0041] Furthermore, such as Figure 6 As shown, the opening and closing inclined plate 61 is provided with a limiting plate 64 at the end away from the opening and closing pivot 63. The limiting plate 64 is composed of a fixed side and a limiting side connected together. The fixed side is fixed to one end of the opening and closing inclined plate 61. The connection angle between the fixed side and the limiting side matches the tilt angle of the opening and closing inclined plate 61 when the feeding cavity 52 is closed. That is, after the material is fed, the opening and closing driver 62 will drive the opening and closing inclined plate 61 to rotate upward to return to the initial state. During this process, the limiting plate 64 will rotate with the opening and closing inclined plate 61. When the limiting side abuts against the side wall of the feeding cavity 52, the limiting side restricts the opening and closing inclined plate 61 from continuing to rotate upward. At this time, the upper and lower opening and closing inclined plates 61 are just in the state of the upper and lower positions inside the closed feeding cavity 52.
[0042] Furthermore, such as Figure 3 As shown, the lifting and feeding device 2 includes a storage section 22, a lifting section 23, and a pouring section 24. The pouring section 24 is located above the lifting section 23, and the storage section 22 is located below the lifting section 23. The frame 1 is equipped with surrounding plates around the storage section 22, and a return soft baffle 71 is provided above the storage section 22. A closed storage bin 7 is formed between the return soft baffle 71, the storage section 22, and the surrounding plates. During operation, the material is poured into this storage bin 7. The material is lifted and fed into the lifting section 23 along with the lifting conveyor chain plate in the storage section 22. During this process, the storage plate 25 on the lifting conveyor chain plate and the return soft baffle 71 cooperate to hold the material in the storage section 22, thereby preventing the material from slipping back.
[0043] Furthermore, the vertical vibration channel 3 is a dual-channel design. This dual-channel design increases the material conveying speed, thereby improving the feeding speed of the large material lifting feeder. Additionally, a feeding sensor 33 is installed at the connection point between each channel and the transition conveyor belt 4. Figure 1 and Figure 2 As shown, during operation, when the left feed sensor 33 detects that the material on the left flow channel is being conveyed to the transition conveyor belt 4, it will transmit a signal to the right straight vibrator 34. The right straight vibrator 34 will immediately stop vibrating, and the material on the right flow channel will no longer be conveyed forward. Similarly, when the right feed sensor 33 detects that the material on the right flow channel is being conveyed to the transition conveyor belt 4, the material on the left flow channel will no longer be conveyed forward, which can prevent the amount of material conveyed forward in the transition conveyor belt 4 from mixing and affecting subsequent feeding.
[0044] Furthermore, each channel of the vertical vibration channel 3 includes a vertical vibrator 34, a primary channel 35, and a secondary channel 36. The primary channel 35 and the secondary channel 36 are inclinedly arranged on the vertical vibrator 34. This design allows for centralized control of material dispersion and screening to ensure normal material supply in the vertical vibration channel 3. The connection between the primary channel 35 and the secondary channel 36 forms a stepped design, i.e., there is a height difference between the primary channel 35 and the secondary channel 36, which further disperses the material.
[0045] The material distribution guide 31 is located on the primary flow channel 35, and the screening port 32 is located on the secondary flow channel 36. The steps formed by the connection between the primary flow channel 35 and the secondary flow channel 36, as well as the steps formed by the material distribution guide 31 and the primary flow channel 35, all contribute to widening the gap between materials, thereby ensuring normal feeding of the large material lifting and feeding unit.
[0046] Furthermore, such as Figure 2 As shown, side guide plates 41 are provided on both sides of the transition conveyor belt 4. The size of the opening formed at the end of the side guide plates 41 matches the width of the double flow channel, and the size of the opening formed at the front end of the side guide plates 41 matches the width of the feed inlet of the feeding cavity 52, so that the material can smoothly transition from the straight vibration flow channel 3 into the feed inlet of the feeding device 5.
[0047] In summary, the lifting and feeding device 2 is inclined on the frame 1 with an inclination range of 60°-70°. This design effectively reduces the occurrence of oversized materials falling from the lifting chain plate storage plate 25 during the lifting and feeding process, making it suitable for lifting and feeding oversized materials. Multiple designs in the direct vibration channel 3 can separate and screen oversized materials, increasing the spacing between materials and preventing material accumulation, thus ensuring normal feeding of the oversized material lifting and feeding unit. Furthermore, the discharge chamber 52 has an upper opening structure 53 and a lower opening structure 54, with the opening and closing fulcrum of the upper and lower opening structures 53 located on one side inside the discharge chamber 52. Compared to setting a rotating paddle structure in the middle of the discharge chamber 52, this doubles the storage space, effectively preventing oversized materials from jamming and making it suitable for feeding oversized materials. All three of these features improve the stability of the oversized material lifting and feeding unit's operation.
[0048] 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.
