Description

Technical Field

[0001] This application relates to the technical field of material conveying, and in particular to a material distribution device. Background Technology

[0002] Plastic products are generally injection molded using injection molding machines. There are two ways to feed plastic granules: manual operation and automatic feeding. In the automatic feeding method, a single injection molding machine uses a suction machine connected to the discharge hopper. The material is sent into the discharge hopper of the injection molding machine through the connecting bin of the suction machine.

[0003] In the process of feeding multi-colored materials, a single feeder cannot transport multiple colors of materials at the same time. In order to facilitate the simultaneous transport of multi-colored materials, a distribution station is set up between the feeder and the material storage bin in the existing technology. The corresponding materials can be quickly connected and transported through the connection between the distribution station and the feeding hose.

[0004] Existing distribution station structures, such as the utility model patent with publication number CN214779276U, disclose "a plastic granule raw material distribution station," which includes a frame and several main and branch air conveying pipes mounted on the frame. Multiple branch air conveying pipes can connect to the discharge hoses of corresponding material storage bins. The main air conveying pipes collect the materials conveyed by the branch air conveying pipes and connect to the suction pipe of the feeder to achieve feeding. In the above distribution station structure, the main and branch air conveying pipes are generally fixedly connected to the frame by welding, resulting in a fixed position for each main and branch air conveying pipe on the frame. The lengths of the discharge hoses of each material storage bin and the suction pipe of the feeder need to be adapted to the positions of the main and branch air conveying pipes to achieve connection. Once the position of the injection molding machine or material storage bin changes due to plant design, there may be situations where the discharge hoses or suction pipes cannot connect to the distribution station due to length issues, and moving the entire distribution station is quite troublesome. Utility Model Content

[0005] To facilitate flexibility when connecting discharge hoses or suction pipes, this application provides a material distribution device.

[0006] The material distribution device provided in this application adopts the following technical solution:

[0007] A material dispensing device includes a frame and further includes:

[0008] At least one distribution unit, the distribution unit comprising a manifold and at least one branch pipe, the manifold having at least one outlet, the branch pipe connected to the manifold, the branch pipe having an inlet; and

[0009] A sliding assembly for connecting a distribution unit to a rack, the sliding assembly including a first frame and a sliding component, the first frame being connected to the rack;

[0010] The first frame has a sliding groove with openings on both sides. The sliding component includes a clamping tube and a guide block extending from one end of the clamping tube toward the sliding groove. The guide block is slidably connected in the sliding groove, and the clamping tube is connected to the manifold and / or branch pipe.

[0011] By adopting the above technical solution, multiple distribution units can independently or synchronously convey different materials. Materials enter the manifold from the inlet of the branch pipe and are finally output through the inlet of the manifold. The suction pipe of the suction machine is connected to the inlet. When different materials need to be fed, simply connect the discharge hose of the material storage bin to the inlet of the branch pipe. Furthermore, the manifold is slidably connected to the frame via a sliding assembly, allowing adjustment of the relative positions of the discharge and inlets. During adjustment, the clamping pipe, connected to the manifold and / or branch pipe, and the branch pipe connected to the manifold, slides within the groove of the first frame, driving the movement of the entire manifold and branch pipe, thereby adjusting the interface position and improving the flexibility of pipeline connections when conveying different materials.

[0012] Preferably, the chute has a guide opening, the first frame has a hook segment extending toward the guide opening, the hook segment forms a hook portion on both side walls of the chute, the guide block has a groove that engages with the hook portion, and the hook portion is slidably connected to the groove.

[0013] By adopting the above technical solution, the hook engages with the groove of the guide block to achieve a limiting position, thereby achieving the installation limiting position when the manifold and / or branch pipe are not sliding and adjusted relative to the first frame while realizing the guiding sliding of the manifold and / or branch pipe.

[0014] Preferably, the outer surface of the hook segment is an arc-shaped surface, and the hook segment abuts against the manifold / branch pipe.

[0015] By adopting the above technical solution, when the manifold and / or branch pipe slide relative to the first frame, the arc-shaped surface of the hook section can reduce the frictional resistance between the two.

[0016] Preferably, the sliding assembly further includes:

[0017] The second frame is connected to the frame and has the same structure as the first frame;

[0018] Both the manifold and the branch pipe are connected to clamping pipes. The clamping pipes on the branch pipes are slidably connected to the first frame, and the clamping pipes on the manifold are connected to the second frame.

[0019] By adopting the above technical solution, adding a second frame not only improves the installation stability of the distribution unit, but also improves the stability of the distribution unit during sliding.

[0020] Preferably, the manifold includes:

[0021] The main body is inclined and connected to the frame;

[0022] First discharge pipe; and

[0023] Second discharge pipe;

[0024] The discharge port includes a first discharge port opened in the first discharge pipe and a second discharge port opened in the second discharge pipe. The first discharge port is lower than the second discharge port, and a first plug is provided in the first discharge port / second discharge port.

[0025] By adopting the above technical solution, the split-type manifold structure facilitates customized combinations to achieve length adjustment and replacement. Secondly, the different heights of the two discharge ports of the first and second discharge pipes allow for more flexible material conveying in different directions.

[0026] Preferably, the sliding assembly further includes:

[0027] The third frame is connected to the frame and has the same structure as the first frame;

[0028] The main body, the first discharge pipe, and the branch pipe are all connected to clamping pipes. The clamping pipe on the branch pipe is slidably connected to the first frame, the clamping pipe on the main body is connected to the second frame, and the clamping pipe on the first discharge pipe is connected to the third frame.

[0029] By adopting the above technical solution, adding a third frame not only improves the installation stability of the distribution unit, but also improves the stability of the distribution unit during sliding.

[0030] Preferably, the dispensing unit further includes a first pipe clamp, the first pipe clamp comprising:

[0031] The sleeve has a connecting channel and a first connecting port and a second connecting port that connect the connecting channel. The sleeve also has a notch on its outer peripheral wall that connects the connecting channel.

[0032] The first connecting plate extends outward from the outer peripheral wall of the sleeve and is positioned on one side of the notch;

[0033] A second connecting plate extends outward from the outer peripheral wall of the sleeve, and the second connecting plate is positioned on the other side of the notch; and

[0034] Adjusting element, used to connect the first connecting plate and the second connecting plate;

[0035] The first connection port is connected to one end of the branch pipe, and the second connection port is connected to the second plug. When the adjusting member rotates relative to the first and second connecting plates, it can drive the first and second connecting plates to move towards or away from each other to increase or decrease the size of the connection channel.

[0036] By adopting the above technical solution, the setting of the first pipe clamp can improve the connection stability of the material storage silo after the discharge hose and branch pipe are connected, and the tightness of the connection can be adjusted by changing the size of the connection channel through the rotation of the adjusting component.

[0037] Preferably, the first connecting plate is further provided with a first limiting block, and the second connecting plate is further provided with a second limiting block. The first limiting block has a slot at its end. When the first connecting plate and the second connecting plate move toward each other, the end of the second limiting block can be locked in the slot to suppress the relative displacement of the first connecting plate and the second connecting plate in one direction.

[0038] By adopting the above technical solution, the adjusting component has the maximum shrinkage stroke when the diameter of the connecting channel is reduced. When the shrinkage stroke is at its maximum, the end of the second limiting block is locked in the slot. At this time, the first connecting plate and the second connecting plate can no longer move towards each other, thus reducing the squeezing and wear on the pipe fittings during connection.

[0039] Preferably, the first pipe clamp further includes a connecting sleeve installed in the connecting channel, one end of the connecting sleeve being connected to the branch pipe, and the other end of the connecting sleeve being connected to the second plug.

[0040] By adopting the above technical solution, the connecting sleeve is set as a detachable consumable, which can avoid the sleeve from directly contacting the branch pipe and the discharge hose. The material of the connecting sleeve can be a material with a certain degree of elastic deformation and good wear resistance, such as plastic, which can reduce compression wear. After long-term use, the connecting sleeve can be directly replaced to improve service life.

[0041] Preferably, the main body includes at least two detachably connected main body segments, the first discharge pipe and / or the second discharge pipe are detachably connected to the main body segments, and second pipe clamps are provided between the first discharge pipe and / or the second discharge pipe and the main body segments as well as between two adjacent main body segments.

[0042] By adopting the above technical solution, after the split manifolds are connected to each other, the connection strength at the connection point is achieved by using the second pipe clamp.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. By setting up sliding components, any distribution unit can slide relative to the frame, improving the flexibility of pipeline connection;

[0045] 2. By setting the first to third frames, the stability of the connection and support for the distribution unit can be improved, while the guiding performance during sliding can also be improved;

[0046] 3. By setting the first and second pipe clamps, the connection stability of the pipeline and the connection of each part of the split manifold is improved. Attached Figure Description

Detailed Implementation

[0057] The present application will be further described in detail below with reference to the accompanying drawings.

[0058] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0060] Figure 1 The structure of the material distribution device is shown, including a frame 1 and at least one distribution unit 2 connected to the frame 1. The distribution unit 2 is used to connect the material storage bin and the suction machine to realize the operation and transportation of materials. In this embodiment, four distribution units 2 are provided and arranged adjacent to each other.

[0061] The material distribution device also includes a sliding assembly for connecting the frame 1 and the distribution unit 2. The sliding assembly includes a first frame 5, a second frame 6, a third frame 7, and several sliding parts 10. The several sliding parts 10 are connected to the distribution unit 2 and then connected to the corresponding first frame 5, second frame 6, or third frame 7. The first frame 5, second frame 6, and third frame 7 are all connected to the frame 1, thereby realizing the connection between the distribution unit 2 and the frame 1 through the sliding assembly.

[0062] See also Figures 2 to 4 Each distribution unit 2 includes a manifold 3 and at least one branch pipe 4 connected to the outer wall of the manifold 3. In this embodiment, each manifold 3 is connected with five branch pipes 4 at intervals. The length of each branch pipe 4 is from high to low, and the ends of the branch pipes 4 are flush with each other.

[0063] The first frame 5 is installed above the frame 1 and the branch pipe 4 is connected to the first frame 5 through the sliding member 10 connected to the branch pipe 4. It should be noted that the branch pipe 4 is installed in a vertical arrangement, the sliding member 10 is connected to the branch pipe 4, and the first frame 5 is placed on one side of the branch pipe 4.

[0064] The second frame 6 and the third frame 7 are both installed below the frame and are connected to the manifold 3 via a sliding member 10. It should also be noted that the manifold 3 is arranged at an angle, with the second frame 6 connected to the lower side of the manifold 3 and the third frame 7 connected to the upper side of the manifold 3. The positional distribution of the first frame 5, the second frame 6 and the third frame 7 achieves the connection limit between the distribution unit 2 and the frame 1 in the vertical direction.

[0065] In this embodiment, the connection structure between the second frame 6 and the sliding member 10 is specifically shown as an example. The first frame 5, the second frame 6 and the third frame 7 have the same structure, all including sliding grooves 61 with openings on both sides. The opening direction of the sliding grooves 61 is perpendicular to the installation direction of the branch pipe 4. The second frame 6 also has a guide opening that connects to the slide groove 61. The two sides of the guide opening have hook sections 62 extending towards each other. The hook sections 62 and the two side walls of the slide groove 61 enclose a hook part 63. The sliding member 10 includes an integral clamp tube 101 and guide blocks 102 extending outward from both ends of the clamp tube 101. The main body of the clamp tube 101 is arc-shaped and connected to the manifold 3. It is fixedly connected to the manifold 3 by welding. The end of the guide block 102 extends into the slide groove 61. The two sides of the guide block 102 are provided with grooves 103. The two grooves 103 respectively engage with the two hook parts 63. At the same time, the hook parts 63 can slide in the grooves 103, thereby realizing the sliding connection between the manifold 3 and the second frame 6.

[0066] At the same time, the hook segment 62 is configured with an arc-shaped surface on its outer surface, which abuts against the outer surface of the manifold 3, so that relative friction and wear can be reduced when the manifold 3 slides relative to the second frame 6.

[0067] See also Figure 5 and Figure 6 The manifold 3 includes a split main body and a first discharge pipe 32 and a second discharge pipe 33 detachably connected to both ends of the main body. The main body also includes at least two detachably connected main body segments 31. One end of the first discharge pipe 32 and the second discharge pipe 33 are respectively detachably connected to one of the main body segments 31.

[0068] The first discharge pipe 32 is a bent pipe with a first discharge port 321 at one end; the second discharge pipe 33 is a straight pipe with a second discharge port 331 at one end. In this embodiment, the second discharge port 331 is positioned higher than the first discharge port 321 in the vertical direction, and a first plug 332 is provided inside the second discharge port 331, so that the material of the entire manifold 3 is output from the first discharge port 321. Alternatively, the first plug 332 can be connected to the first discharge port 321, and the material of the entire manifold 3 is output from the second discharge port 331.

[0069] One end of the branch pipe 4 has a feed inlet 41, and a first pipe clamp 8 is connected to the end of the branch pipe 4. The first pipe clamp 8 is used to connect the discharge hose of the material storage bin, so that the material is input from the branch pipe 4. A second pipe clamp 9 is provided between the two main sections 31 and between the main section 31 and the first discharge pipe 32. The second pipe clamp 9 has the same structure as the first pipe clamp 8 and is used for connection. When the manifold 3 is connected to the second frame 6 and the third frame 7, the aforementioned clamp 101 is provided on one of the main sections 31 and on the first discharge pipe 32.

[0070] Combination Figures 7 to 9 This embodiment takes the first pipe clamp 8 structure as an example to introduce the specific structure. The first pipe clamp 8 includes a generally cylindrical pipe sleeve 81. The pipe sleeve 81 has a connecting channel 811 and a first connecting port 8111 and a second connecting port 8112 communicating with the connecting channel 811. The first connecting port 8111 is connected to the branch pipe 4. The second connecting port 8112 is used to connect to the external discharge hose. A second plug 83 is provided in the second connecting port 8112. When the second plug 83 is removed, it can be connected to the discharge hose.

[0071] The outer peripheral wall of the sleeve is provided with a notch 812 for connecting the connection channel 811. A first connecting plate 84 and a second connecting plate 85 are provided outwardly on the outer peripheral wall of the sleeve, and the first connecting plate 84 and the second connecting plate 85 are respectively located on both sides of the notch 812. The first pipe clamp 8 also includes an adjusting member 86, which includes an adjusting section 861, a limiting section 862 and a handle 863 connected in sequence. The outer peripheral wall of the adjusting section 861 is provided with external threads. The limiting section 862 and the adjusting section 861 are arranged in a stepped manner, and the connection between the two has a shoulder. The adjusting section 861 passes through the first connecting plate 84 and the second connecting plate 85, and the adjusting section 861 is rotatably connected to the first connecting plate 84. The adjusting section 861 is threadedly connected to the second connecting plate 85. A nut block 87 is provided in the second connecting plate 85, and the adjusting section 861 and the nut block 87 are also threadedly connected. When the adjusting section 861 is driven to rotate by the operating handle 863, the shoulder on the limiting section 862 abuts against the first connecting plate 84. The adjusting section 861 rotates in place, driving the second connecting plate 85 to move away from / towards the first connecting plate 84, thereby changing the size of the notch 812. The change in the size of the notch 812 can increase or decrease the size of the connecting channel 811, thereby adjusting the connection strength of the pipeline.

[0072] The first connecting plate 84 is provided with a first limiting block 841 at its end, and the second connecting plate 85 is provided with a second limiting block 851 at its end. The first limiting block 841 and the second limiting block 851 extend toward each other. The first limiting block 841 has a slot 8411 at its end. When the first connecting plate 84 moves toward the second connecting plate 85, the end of the second limiting block 851 can be locked in the slot 8411 to achieve the contact between the two, thereby limiting the maximum travel of the first connecting plate 84 and the second connecting plate 85 toward each other.

[0073] To reduce the squeezing wear between the first clamp 8 and the branch pipe 4 and the discharge hose, a connecting pipe is also provided inside the sleeve. The connecting pipe is made of a material with a certain elastic deformation capability, such as polyurethane plastic, and one end of the connecting pipe is connected to the end of the branch pipe 4.

[0074] When this distribution device is in use, any one of the distribution units 2 can slide relative to the frame 1. After the adjustment is completed, the second plug 83 of the required feed is removed from the distribution unit 2 and the discharge hose is inserted into the first pipe clamp 8. Similarly, the first discharge pipe 32 or the second discharge pipe 33 on the corresponding manifold 3 is selected to connect to the suction pipe of the suction machine, and the unused first discharge pipe 32 or the second discharge pipe 33 is clamped with the first plug 332. This can realize the simultaneous transfer and conveying of a single material or multiple materials.

[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
