Description

TECHNICAL FIELD

[0001] The utility model relates to a material receiving mechanical equipment technical field, especially a kind of quick rotary table material receiving machine. BACKGROUND

[0002] After material production and processing are completed, the material needs to be collected and transported to the corresponding place for placement, and a material receiving machine for material collection is generally placed at the discharge port of the material production equipment. For example, the material receiving machine disclosed in application No. 2020224141089 includes a rack, a feed hopper, a material receiving mechanism, a driving mechanism, an angle sensor, and a controller. The rack includes a bottom frame and an upper frame, and the bottom frame and the upper frame are fixedly connected by a support. A fixed shaft is arranged between the bottom frame and the upper frame. The feed hopper is fixedly arranged on the upper frame and includes a hopper body, a feed inlet, and a discharge outlet. The material receiving mechanism is rotatably connected to the fixed shaft and includes a rotating disc and a material receiving rack, which are fixedly connected by a support rod. At least two material receiving rings are evenly arranged on the material receiving rack, and the material receiving rings are used to install material receiving bags. A material receiving space for installing the material receiving bags is formed between the material receiving rings and the rotating disc. The material receiving rings corresponding to the discharge outlet are arranged below the discharge outlet. The driving mechanism is arranged on the rack and is used to control the rotation of the material receiving mechanism. The angle sensor is fixedly arranged on the rotating disc through the fixed shaft. The controller is arranged on the rack and is electrically connected to the driving mechanism and the angle sensor to control and adjust the rotation angle of the material receiving mechanism. In application, the position of the material receiving machine is first adjusted so that the feed inlet of the feed hopper is aligned with the discharge outlet of the material production equipment. Then, a material receiving bag is placed on each material receiving ring, and the discharge outlet of the feed hopper is arranged below the material receiving bag. When the material receiving capacity of the material receiving bag reaches the specified requirement, the controller controls the rotating disc to rotate by a certain angle, so that the next empty material receiving bag is located directly below the discharge outlet of the feed hopper. The above steps are repeated to complete the material receiving of each material receiving bag.

[0003] In the above-mentioned material receiving machine, the material receiving bag is stretched out from the opening of the material receiving ring from bottom to top, and then the upper end of the material receiving bag is folded downward and placed outside the material receiving ring. However, as the material continuously falls, the weight of the lower end of the material receiving bag increases, and the material receiving bag tends to tilt to one side. Since the material receiving ring has a circular ring structure, the material receiving bag placed outside the material receiving ring is easy to slide out under force, causing the material receiving bag to tip over and the material to fall out. Moreover, the amount of material entering the material receiving bag is controlled by the time of discharging. When the material reaches the position of the material receiving ring, the material may still continue to be discharged, and the material is easy to overflow and fall to the ground.

[0004] Therefore, the present inventors have conducted in-depth research on the problem and thus have developed the present application. Utility Model Content

[0005] The purpose of this invention is to provide a fast rotary receiving machine to solve the problems of existing receiving machines where the receiving bag easily slips out during receiving, causing the receiving bag to tip over and the material to overflow and fall.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A high-speed rotary feeding machine includes a frame, a rotary disk rotatably mounted on the frame, and several receiving rings suspended above the rotary disk. The receiving rings are spaced apart along the circumferential direction of the rotary disk. The frame has a feed hopper positioned above the receiving rings and aligned vertically with each receiving ring. A connecting member is provided between the receiving rings and the rotary disk for connection. The upper end of the connecting member is connected to the receiving ring, and the lower end is mounted on the rotary disk via a detachable mounting structure. The connecting member has a flared structure that gradually expands from top to bottom. The frame is equipped with a photoelectric detection switch that can be raised and lowered to adjust the installation height. The detection end of the photoelectric detection switch is located at the output end of the feed hopper and can be aligned with the receiving ring of the rotating disk within the feed hopper's range. A positioning proximity switch is installed on the frame outside the rotating disk. The positioning proximity switch is positioned opposite to the photoelectric detection switch. A sensing rod that cooperates with the positioning proximity switch is installed on the rotating disk. Several sensing rods are provided and are arranged one-to-one with each receiving ring. Each sensing rod and each receiving ring are arranged opposite to each other along the radial direction of the rotating disk.

[0008] The aforementioned connector consists of several limiting rods spaced around the circumference of the receiving ring. The limiting rods are inclined outward from top to bottom, and each limiting rod forms the aforementioned horn structure.

[0009] The receiving ring is a closed-loop structure, and a notch is provided on the outer wall of the receiving ring that runs vertically through and communicates with the hollow space of the receiving ring.

[0010] The receiving rings are provided in three parts, and the three receiving rings are evenly spaced along the circumferential direction of the rotating disk. The upper end of the limiting rod is integrally welded to the receiving rings. The bottom surface of the limiting rod is recessed with an upper locking hole. The top surface of the rotating disk is provided with a lower locking hole that runs vertically through the upper locking hole. The limiting rod is installed together with the rotating disk by locking bolts that pass through the lower locking hole and the upper locking hole in sequence. The upper locking hole, the lower locking hole and the locking bolt constitute the above-mentioned disassembly and installation structure.

[0011] The frame is erected outside the rotating disk with a vertical pole. A horizontal connecting rod is installed at the upper end of the vertical pole. The horizontal connecting rod is located in front of the output end of the feed hopper. The photoelectric detection switch is installed at the end of the horizontal connecting rod facing away from the vertical pole. Both the photoelectric detection switch and the output end of the feed hopper can be aligned and fall into the space of each receiving ring as the rotating disk rotates.

[0012] The vertical pole is a telescopic pole that can be raised and lowered and drive the horizontal connecting pole to move up and down.

[0013] The telescopic rod has a lower fixed part, a telescopic part, and an upper connecting part. The lower end of the lower fixed part is connected to the frame. Both the lower fixed part and the telescopic part are hollow rods with open top surfaces. A lower fixing hole communicating with the hollow cavity of the lower fixed part is opened on the outer wall of the upper end of the lower fixed part. The lower end of the telescopic part extends into the upper end of the lower fixed part. Several lower adjusting holes are opened on the outer wall of the lower end of the telescopic part, which are evenly spaced vertically and communicate with the hollow cavity of the telescopic part. The lower fixing holes are aligned with the lower adjusting holes, and the telescopic part passes through the lower fixed part in sequence by lower tightening screws. The fixed hole and its lower adjustment hole are connected to the lower fixed part. The upper outer wall of the telescopic part is provided with an upper fixed hole that communicates with the hollow cavity of the telescopic part. The lower end of the upper connecting part extends into the upper end of the telescopic part. The lower outer wall of the upper connecting part is provided with several upper adjustment holes that are evenly spaced vertically and communicate with the hollow cavity of the upper connecting part. The upper fixed hole and its upper adjustment hole are aligned. The upper connecting part is connected to the telescopic part by passing through the upper fixed hole and its upper adjustment hole in sequence with the upper tightening screw. The upper end of the upper connecting part is connected to the cross connecting rod.

[0014] The sensing rod is vertically installed on the outer wall of the rotating disk, and the top surface of the sensing rod extends beyond the top surface of the rotating disk. There are several sensing rods, and each sensing rod is set in one-to-one correspondence with the axis of each receiving ring, and the axis of each sensing rod and its corresponding receiving ring are on the same straight line.

[0015] Of the three receiving rings, the receiving ring corresponding to the feed hopper is the first receiving ring. Along the clockwise direction of the rotating disk, the three receiving rings are the first receiving ring, the second receiving ring, and the third receiving ring. The outer wall of the rotating disk is provided with three vertically arranged sensing rods, namely the first sensing rod, the second sensing rod, and the third sensing rod. The first sensing rod is arranged opposite to the first receiving ring, and the axes of the first sensing rod and the first receiving ring are on the same straight line. The second sensing rod is arranged opposite to the second receiving ring, and the axes of the second sensing rod and the second receiving ring are on the same straight line. The third sensing rod is arranged opposite to the third receiving ring, and the axes of the third sensing rod and the third receiving ring are on the same straight line. The positioning proximity switch faces one of the sensing rods, and the detection end of the positioning proximity switch faces the rotating disk. The detection end of the positioning proximity switch is higher than the top surface of the rotating disk and lower than the top surface of the sensing rod.

[0016] This novel high-speed rotary feeding machine involves inserting the open end of a receiving bag through the opening of a receiving ring. The upper end of the receiving bag is folded downwards and placed over the upper end of the connector. Receiving bags are then placed on each receiving ring one by one. The height of the photoelectric detection switch is adjusted. If the receiving bag needs to be 80% full, the detection end of the photoelectric detection switch is aligned with the 80% full position of the receiving bag. Material falls from the hopper into one of the receiving bags. When the receiving bag is 80% full, the photoelectric detection switch activates, stopping the feeding. The rotary table rotates until the detection end of the positioning proximity switch aligns with the next sensing rod. The rotary table then stops moving, aligning the next receiving ring with the next receiving ring. Below the feed hopper, the empty receiving bags are receiving material. Once the receiving bags are full, workers can remove them from the rotating disc and put them back on. Each receiving ring corresponds to the feed hopper in sequence, allowing each receiving bag to circulate and receive material, improving receiving efficiency. Compared with existing technologies, the flared structure of the connector supports the side of the receiving bag. Even if the receiving bag tilts to one side, the connector can still support it, preventing it from tilting and falling over. Moreover, the connector opens the top of the receiving bag, preventing it from sliding down. Furthermore, the photoelectric detection switch stops feeding when the receiving bag reaches a certain height, preventing material from overflowing and falling to the ground. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0018] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0019] A high-speed rotary feeding machine, such as Figure 1 As shown, the device includes a frame 1, a rotating disk 2 rotatably mounted on the frame 1, and several receiving rings 3 suspended above the rotating disk 2. Each receiving ring 3 is spaced apart along the circumferential direction of the rotating disk 2. The frame 1 is provided with a feeding hopper 4 located above the receiving rings 3 and aligned vertically with each receiving ring 3. The feeding hopper 4 is a hollow structure with open sides. The feeding hopper 4 is inclined downward from back to front. The upper end of the feeding hopper 4 is connected to the discharge port of the material production equipment, and the lower end of the feeding hopper 4 is connected vertically with one of the receiving rings 3. The feeding hopper 4 is suspended above the receiving rings 3. The specific structure of the feeding hopper 4 and the way the rotating disk 2 is rotatably mounted on the frame are well known to those skilled in the art and will not be described in detail here. In application, the receiving bag extends from the bottom up through the opening of the receiving ring 3, and then the upper end of the receiving bag is folded down and placed on the outside of the receiving ring 3. Receiving bags are placed on each receiving ring 3 in a corresponding manner, and the receiving bag on one of the receiving rings 3 is received below the feed hopper. The material is discharged from the outlet of the material production equipment into the feed hopper and falls into the receiving bag.

[0020] A connector 5 is provided between the receiving ring 3 and the rotating disk 2 for connecting the receiving ring 3 and the rotating disk 2. The upper end of the connector 5 is connected to the receiving ring 3, and the lower end of the connector 5 is installed on the rotating disk 2 through a disassembly and installation structure. The connector 5 has a horn structure that gradually expands from top to bottom. Specifically, the connector 5 is composed of several limiting rods that are spaced around the circumference of the receiving ring 3. The limiting rods are inclined outward from top to bottom. Four limiting rods are connected to one receiving ring 3, and the limiting rods form the horn structure. Three receiving rings 3 are provided, evenly spaced along the circumference of the rotating disk 2. Both the limiting rod and the receiving rings 3 are metal parts. The upper end of the limiting rod is integrally welded to the receiving ring 3. The bottom surface of the limiting rod has a recessed upper locking hole. The top surface of the rotating disk 2, located at the position of the upper locking hole, has a through-hole lower locking hole. The limiting rod is locked to the rotating disk 2 by locking bolts that pass sequentially through the lower and upper locking holes. The upper and lower locking holes and the locking bolts constitute the aforementioned disassembly and installation structure. In application, each limiting rod is locked onto the rotating disk 2, thereby achieving the installation of the receiving rings 3. The disassembly and installation structure allows for the disassembly and installation of the receiving rings 3. The required number of receiving rings 3 can be installed, and the corresponding receiving rings and limiting rods can be replaced according to the size of the receiving bag. Furthermore, the limit rods are designed in a funnel shape, which allows the limit rods to open up the folded position of the receiving bag when the upper end of the receiving bag is folded downwards, making it less likely for the receiving bag to slide down. In addition, the hollow space formed by the limit rods provides support for the receiving bag, and when the lower end of the receiving bag tilts to one side, the receiving bag is not likely to slide out or tip over due to the limit rods.

[0021] The frame 1 is equipped with a photoelectric detection switch 6 that can be raised and lowered to adjust its installation height. The detection end of the photoelectric detection switch 6 is located at the output end of the feed hopper 4 and is within the range of the receiving ring 3 at the feed hopper 4 corresponding to the rotating disk 2. Specifically, a vertical rod 7 is erected on the frame 1 outside the rotating disk 2, and a horizontal connecting rod 8 is horizontally installed at the upper end of the vertical rod 7. The vertical rod 7 is a telescopic rod that can be raised and lowered and drive the horizontal connecting rod 8 to move up and down. The horizontal connecting rod 8 is located in front of the output end of the feed hopper 4, and the end of the horizontal connecting rod 8 facing away from the vertical rod 7 is installed with... With the aforementioned photoelectric detection switch 6, both the photoelectric detection switch 6 and the output end of the feed hopper 4 can be aligned and fall into the space of each receiving ring 3 as the rotating disk 2 rotates. The photoelectric detection switch 6 is inclined from top to bottom, and the detection end of the photoelectric detection switch 6 faces the inner wall of the receiving bag. The photoelectric detection switch 6 is electrically connected to the material production equipment so that when the photoelectric detection switch 6 is activated, the discharge port of the material production equipment stops discharging material. The electrical connection method of the photoelectric detection switch 6 to control the stopping of discharging is well known to those skilled in the art and will not be described in detail here. In application, the detection end of the photoelectric detection switch 6 is oriented towards the 8 / 10 full position of the receiving bag. The discharge port of the material production equipment continues to discharge material. When the material falls to 8 / 10 full, the photoelectric detection switch 6 is activated, and the discharge port of the material production equipment stops discharging material, preventing the material from falling to the ground. The photoelectric detection switch 6 can be adjusted in height, that is, the height of the photoelectric detection switch 6 can be adjusted according to the material height of the receiving bag.

[0022] A positioning proximity switch 11 is installed on the frame 1 outside the rotating disk 2. The positioning proximity switch is positioned opposite to the photoelectric detection switch. A sensing rod 21 that senses the positioning proximity switch 11 is installed on the rotating disk 2. Several sensing rods 21 are provided and are arranged one-to-one with each receiving ring 3. Each sensing rod and each receiving ring are arranged opposite to each other along the radial direction of the rotating disk. Specifically, the sensing rod 21 is vertically installed on the outer side wall of the rotating disk 2, and the top surface of the sensing rod 21 extends out of the top of the rotating disk 2. Outwardly, each sensing rod 21 is arranged in a one-to-one correspondence with the axis of each receiving ring 3, and the axis of each sensing rod 21 and its corresponding receiving ring is on the same straight line. That is, among the three receiving rings 3, the receiving ring 3 corresponding to the feed hopper 4 is the first receiving ring 31. Along the clockwise direction of the rotating disk 2, the three receiving rings 3 are the first receiving ring 31, the second receiving ring 32, and the third receiving ring 33. The outer wall of the rotating disk 2 is provided with three vertically arranged sensing rods 21 that are arranged in a one-to-one correspondence with each receiving ring. The sensing rod 21 is divided into a first sensing rod 211, a second sensing rod 212, and a third sensing rod 213. The first sensing rod 211 is positioned opposite to the first receiving ring 31, and their axes are collinear. The second sensing rod 212 is positioned opposite to the second receiving ring 32, and their axes are collinear. The third sensing rod 213 is positioned opposite to the third receiving ring 33, and their axes are collinear. On the same straight line, the positioning proximity switch 11 faces one of its sensing rods 21. The detection end of the positioning proximity switch 11 is horizontally arranged and faces the rotating disk 2. The detection end of the positioning proximity switch 11 is higher than the top surface of the rotating disk 2 and lower than the top surface of the sensing rod. The positioning proximity switch is installed between the vertical rod 7 and the rotating disk 2. The positioning proximity switch 11 is electrically connected to the rotating disk. The electrical connection method of activating the positioning proximity switch 11 to stop the rotating disk is a well-known technique to those skilled in the art and will not be described in detail here. In application, the rotating disk 2 rotates. When the detection end of the positioning proximity switch 11 is aligned with the second sensing rod 212, the rotating disk 2 stops moving. At this time, the first receiving ring 31 is below the feeding hopper 4, the receiving bag reaches the required material height, and feeding stops, while the rotating disk rotates. Similarly, when the rotating disk rotates until the detection end of the positioning proximity switch 11 is aligned with the first sensing rod 211, the rotating disk 2 stops moving, the third receiving ring 33 is below the feeding hopper 4, the receiving bag reaches the required material height, and feeding stops, while the rotating disk rotates. When the detection end of the positioning proximity switch 11 is aligned with the third sensing rod 213, the second receiving ring 32 is below the feeding hopper 4, the receiving bag reaches the required material height, and feeding stops, while the rotating disk rotates until the first receiving ring 31 is below the feeding hopper 4. This cycle repeats, ensuring that each receiving bag receives material accurately.

[0023] In this novel high-speed rotary receiving machine, the open end of the receiving bag enters between the two limiting rods of a receiving ring and exits through the opening of the receiving ring. The upper end of the receiving bag is folded downwards and placed over the upper ends of each limiting rod. Receiving bags are then placed on each receiving ring 3 one by one. The height of the photoelectric detection switch 6 is then adjusted. If the receiving bag needs to be 8 / 10 full, the detection end of the photoelectric detection switch 6 is aligned with the 8 / 10 full position of the receiving bag. Material falls from the hopper into one of the receiving bags. When the receiving bag is 8 / 10 full, the photoelectric detection switch 6 is activated, stopping the feeding. The rotary disc 2 rotates until the detection end of the positioning proximity switch 11 aligns with the next sensing rod 21, at which point the rotary disc 2 stops moving. The next receiving ring is positioned below the feed hopper 4. At this time, the empty receiving bag is receiving material. When the receiving bag is full of material, the worker can remove the receiving bag from the rotating plate 2 and put it back on. Each receiving ring 3 corresponds to the feed hopper 4 in sequence, so that the receiving bag can circulate and receive material, improving the receiving efficiency. Compared with the existing technology, the funnel space formed by each limiting component supports the side of the receiving bag. Even if the receiving bag tilts to one side, each limiting rod can support the receiving bag and prevent it from tilting and falling. Moreover, each limiting rod opens the upper end of the receiving bag, making it less likely for the receiving bag to slide down. In addition, the setting of the photoelectric detection switch 6 stops the feeding when the receiving bag reaches a certain height, making it less likely for the material to overflow and fall to the ground.

[0024] In this invention, the receiving ring 3 is preferably a closed-loop structure, and the outer wall of the receiving ring 3 has a notch 100 that runs vertically through and communicates with the hollow space of the receiving ring 3. In application, when the receiving bag is placed on the receiving ring 3, the notch 100 causes the receiving bag to be positioned at the edge of the notch, forming an angular rather than smooth structure, making it difficult for the receiving bag to slip out of the receiving ring 3.

[0025] The telescopic rod has a lower fixing part 71, a telescopic part 72, and an upper connecting part 73. The lower end of the lower fixing part 71 is connected to the frame 1. Both the lower fixing part 71 and the telescopic part 72 are hollow rods with open top surfaces. A lower fixing hole 200 communicating with the hollow cavity of the lower fixing part 71 is provided on the outer wall of the upper end of the lower fixing part 71. The lower end of the telescopic part 72 extends into the upper end of the lower fixing part 71. A plurality of lower adjusting holes 300 are provided on the outer wall of the lower end of the telescopic part 72, which are evenly spaced vertically and communicate with the hollow cavity of the telescopic part 72. The lower fixing holes 200 are aligned with the lower adjusting holes 300, and the telescopic part 72 passes through the lower fixing holes 200 and the lower adjusting holes 300 in sequence by a lower tightening screw. The adjustment hole 300 is connected to the lower fixing part 71. The upper outer wall of the telescopic part 72 is provided with an upper fixing hole 400 that communicates with the hollow cavity of the telescopic part 72. The lower end of the upper connecting part 73 extends into the upper end of the telescopic part 72. The lower outer wall of the upper connecting part 73 is provided with a plurality of upper adjusting holes 500 that are evenly spaced vertically and communicate with the hollow cavity of the upper connecting part 73. The upper fixing hole 400 and one of the upper adjusting holes 500 are aligned. The upper connecting part 73 is connected to the telescopic part 72 by passing through the upper fixing hole 400 and one of the upper adjusting holes 500 in sequence with the upper tightening screw. The upper end of the upper connecting part 73 is connected to the end of the cross rod 8 facing away from the photoelectric detection switch 6. In application, the lower fixing hole 200 is aligned with its lower adjusting hole 300 to adjust the telescopic part 72 to the required height. Similarly, the fixing hole 400 is aligned with its upper adjusting hole 500 to adjust the lower fixing part 71 to the required height. Ultimately, the height between the photoelectric detection switch 6 and the receiving bag can be adjusted to adapt to the application of different receiving bags.

[0026] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
