DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0026] In order to facilitate understanding of the technical solutions of the present application, the feeding amount of the existing chain plate conveyor is described as follows: when the existing chain plate conveyor conveys materials, the materials on the chain plate may roll, resulting in uneven distribution of the materials on the chain plate, and the accumulated materials may be directly fed into the downstream process, which may cause the downstream equipment to be blocked, and the machine needs to be stopped for cleaning, affecting the efficiency.

[0027] An embodiment of the present application provides a powder preparation system, which comprises a feeding mechanism capable of effectively controlling the feeding amount, thereby avoiding the blocking of the downstream equipment due to the failure of the feeding mechanism to control the feeding amount.

[0028] As Figure 1 and Figure 2As shown, the feeding mechanism comprises a vibrating feeder 110 and a chain plate conveyor 120. The vibrating feeder 110 has a discharge port 1121. The chain plate conveyor 120 comprises a conveying chain plate 121 and a plurality of partitions 122, a first baffle 123 and a second baffle 124 arranged on the conveying chain plate 121. The plurality of partitions 122 are uniformly spaced along the length direction of the conveying chain plate 121; the first baffle 123 and the second baffle 124 are respectively arranged at the two side edges of the conveying chain plate 121 in the width direction, and any two adjacent partitions 122 can be enclosed with the first baffle 123 and the second baffle 124 to form a material carrying groove 125.

[0029] During the rotation of the conveying chain plate 121, each material carrying groove 125 can pass through a material receiving position corresponding to the discharge port 1121 to obtain the material output by the discharge port 1121 at the material receiving position.

[0030] With the above feeding mechanism, the conveying chain plate 121 forms a plurality of material carrying grooves 125, each material carrying groove 125 can receive the material output by the discharge port 1121 when passing through the material receiving position, and then the conveying chain plate 121 rotates to convey the material in the material carrying groove 125 to the downstream. The conveying chain plate 121 rotates at a uniform speed, and each material carrying groove 125 has the same duration when passing through the material receiving position, which can ensure the uniformity of the amount of material in each material carrying groove 125. At the same time, the two adjacent material carrying grooves 125 are separated by the partitions 122, so that the material will not roll into other material carrying grooves 125 during the conveying process, i.e. the material will not be accumulated. In this way, the amount of feeding can be effectively controlled to avoid the situation that the downstream equipment is blocked due to too much feeding.

[0031] Further, as an example, the conveying chain plate 121 comprises a plurality of chain plates, the two adjacent chain plates are separated by the above-mentioned partitions 122, and the two ends of the chain plate are enclosed by the first baffle 123 and the second baffle 124, so that the chain plate, the two partitions 122 and the first baffle 123 and the second baffle 124 enclose the above-mentioned material carrying groove 125. In addition, it should be noted that the number of the first baffle 123 and the second baffle 124 is preferably multiple, i.e. one first baffle 123 and one second baffle 124 are arranged between each two adjacent partitions 122. Of course, in other embodiments, the first baffle 123 and the second baffle 124 can also adopt flexible plates that can be bent and deformed, at this time, the first baffle 123 and the second baffle 124 do not need to be arranged in multiple pieces.

[0032] In one embodiment, the vibrating feeder 110 comprises a vibrating disc 111 and a discharging member 112, the discharging member 112 is connected with the vibrating disc 111, the discharging member 112 has a discharging opening 1121 and a feeding opening in communication with the discharging opening 1121, the feeding opening is in communication with the discharging end of the vibrating disc 111. In this way, after the material is conveyed to the vibrating disc 111, the vibrating disc 111 and the discharging member 112 vibrate to vibrate the material to the discharging member 112, and then the material is conveyed to the material loading groove 125 on the chain plate conveyor 120 through the discharging opening 1121 of the discharging member 112. It can be understood that the discharging member 112 vibrates with the vibrating disc 111, which can also avoid the material being stuck at the discharging member 112.

[0033] Further, the vibrating feeder 110 further comprises a vibration source 113, the vibration source 113 is connected with the vibrating disc 111 to provide power for the vibration of the vibrating disc 111 and the discharging member 112. Optionally, the vibration source 113 comprises a vibrating motor and a transmission structure connected with the vibrating motor and the vibrating disc 111, the vibrating motor and the transmission structure are conventional structures, which will not be described here.

[0034] In one embodiment, the vibrating feeder 110 further comprises a first frame 114, the vibrating disc 111 is movably arranged on the first frame 114, so that the vibrating disc 111 can vibrate relative to the first frame 114. It can be understood that the vibrating disc 111 can be connected with the first frame 114 through an elastic structure, such as a spring, etc., to reduce the vibration transmitted to the first frame 114 while realizing the vibration of the vibrating disc 111. Of course, in other embodiments, the vibrating disc 111 can also be arranged on the first frame 114 in other ways, which is not limited here.

[0035] In one embodiment, the feeding mechanism further comprises a guide member 130, the guide member 130 is arranged corresponding to the discharging opening 1121 of the discharging member 112, and is located between the discharging member 112 and the chain plate conveyor 120, for guiding the material conveyed by the discharging opening 1121 to enter the material loading groove 125 located at the receiving position.

[0036] It is understood that, in general, in order to reduce the space occupied by the chain conveyor 120, the width of the chain conveyor 120 will be limited by the site; at the same time, the unloading member 112 will vibrate with the vibrating plate 111 during the unloading process. If the material output from the unloading port 1121 is directly received through the loading trough 125, the material may fly out of the unloading port 1121 due to vibration and out of the chain conveyor 120. To prevent the material from flying out, the above-mentioned guide member 130 is provided. The guide member 130 has a guide channel running through both ends of itself. The size of the opening of the guide channel facing the unloading member 112 is larger than the size of the opening facing the conveying chain 121. In addition, in the width direction of the conveying chain 121, the size of the opening of the guide channel facing the conveying chain 121 matches the size of the loading trough 125, so as to ensure that the material output from the unloading member 112 is received and conveyed to the loading trough 125.

[0037] It should be noted that, specifically Figure 1 In the illustrated embodiment, a vibrating feeder 110 is located upstream of the conveyor chain 121. The vibrating feeder 110 can stabilize the discharge to a certain extent, that is, ensure the uniformity of the material output. Therefore, in this embodiment, the length of the guide member 130 is extended along the length direction of the conveyor chain 121 to further ensure that the material output from the discharge port 1121 is received and prevented from flying out. Of course, in other embodiments, a flexible bag can also be provided at the discharge port 1121, with one end of the bag communicating with the discharge port 1121 and the other end extending into the guide member 130 and communicating with the material guide channel. This ensures that while the material is conveyed to the material guide channel, vibration is prevented from being transmitted to the guide member 130 and the conveyor chain 121.

[0038] In one embodiment, the chain conveyor 120 includes a horizontal section and a climbing section, the discharge port 1121 corresponds to the end of the horizontal section away from the climbing section, and the end of the climbing section away from the horizontal end corresponds to the downstream equipment. It should be explained that the above-mentioned horizontal section is Figure 1 The middle conveying chain plate 121 keeps the horizontal part, and the climbing section is the part where the conveying chain plate 121 gradually climbs. Further, the guide member 130 is provided in the horizontal section for guiding the material outputted by the discharge port 1121 into the loading trough 125 located at the material receiving position at the horizontal section.

[0039] It should be noted that in this embodiment, the downstream of the chain conveyor 120 is a crusher, and the crusher's feed opening is at a relatively high height, so a climbing section is provided to lift and convey the material to the crusher's feed opening. Furthermore, if only a climbing section were provided, one end of the inclined climbing section would need to correspond with the discharge opening 1121. The small distance between the discharge opening 1121 and the climbing section would make it inconvenient to install other structures, such as the material guide 130. Of course, other embodiments can also be configured based on the conditions of the upstream and downstream equipment, such as providing only a horizontal section or a gradually descending descending section, without limitation here.

[0040] In one embodiment, the chain conveyor 120 further comprises a driving assembly 126 connected with the conveying chain plates 121 to drive the conveying chain plates 121 to rotate circularly to realize the conveying of the materials. It should be noted that the driving assembly 126 to drive the conveying chain plates 121 to rotate is a conventional means, which is usually realized by a motor and a transmission belt, and will not be described here.

[0041] In one embodiment, the chain conveyor 120 further comprises a second rack 127, and the driving assembly 126 and the conveying chain plates 121 are arranged in the second rack 127, and the conveying chain plates 121 can rotate circularly. In this embodiment, the conveying chain plates 121 are usually arranged on the second rack 127 in the form of a roller, and the roller can also realize the bending of the conveying chain plates 121, so as to realize the circular rotation of the conveying chain plates 121 and the turning of the conveying chain plates 121, i.e. the turning from the horizontal section to the climbing section.

[0042] It should be noted that the above embodiment mainly describes the structure of the feeding mechanism, and the feeding mechanism in the above embodiment can effectively control the feeding amount. Next, the equipment downstream of the feeding mechanism will be described.

[0043] In one embodiment, the powder preparation system further comprises a crusher, and the crusher is located downstream of the chain conveyor 120, i.e. one end of the climbing section of the chain conveyor 120 away from the horizontal section is located above the inlet of the crusher to receive the materials conveyed by the chain conveyor 120. As can be known from the above embodiment, when a conventional chain conveyor 120 is used to convey the materials to be crushed, the feeding amount cannot be effectively controlled, and when the feeding amount is too large, the crusher will be blocked, and the crushing efficiency will be affected.

[0044] By using the feeding mechanism provided in the present application, since the conveying chain plates 121 rotate at a constant speed, the time length of each material loading groove 125 passing through the material receiving position is the same, which can ensure the uniformity of the amount of materials in each material loading groove 125, and meanwhile, the adjacent two material loading grooves 125 are separated by the partition plates 122, so that the materials will not roll into other material loading grooves 125 during the conveying of the materials, i.e. the materials will not be accumulated. In this way, the feeding amount can be effectively controlled, and the situation that the crusher is blocked due to the excessive feeding amount can be avoided.

[0045] In one embodiment, the powder preparation system further comprises a grinding machine and a screening machine, and the grinding machine and the screening machine are arranged in sequence downstream of the crusher. The grinding machine can receive the materials crushed by the crusher and grind the materials to form powder, and the screening machine can receive the powder generated by the grinding machine and screen the powder to screen out the powder meeting the requirements.

[0046] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
