Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a material hopper unloading device. Background Technology

[0002] In industrial production, especially in scenarios involving the conveying and metering of powder and granular materials, hoppers, as key equipment for material storage and conveying, directly affect the efficiency of the production line, product quality, and the stability of the production process. Traditional hopper designs typically feature a fixed-height discharge pipe, but this design has gradually revealed many limitations when dealing with diverse production needs and complex operating conditions.

[0003] Problems with the existing fixed height design of the hopper discharge pipe:

[0004] 1. Poor adaptability

[0005] Different production processes have different requirements for material feeding height. For example, in some production stages that require precise material delivery to specific heights or positions, such as automated packaging lines and multi-layer material mixing processes, fixed-height feeding pipes cannot be flexibly adjusted according to actual needs, leading to inaccurate material delivery and affecting the smooth progress of subsequent production steps. Moreover, when the installation height of the material receiving equipment changes, fixed-height feeding pipes are difficult to adapt, requiring redesign or replacement of the hopper, increasing production costs and time.

[0006] 2. Poor material flow control

[0007] The flow of materials in the hopper is affected by various factors, such as particle size, moisture content, and viscosity. A fixed-height feed pipe cannot be adjusted according to the characteristics of the material, easily leading to problems such as material blockage and poor feeding. For example, for highly viscous materials, if the feed pipe height is inappropriate, the material may form bridging phenomena inside the pipe, hindering normal flow, reducing production efficiency, and even requiring shutdown for cleaning, increasing equipment maintenance costs and downtime losses. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material feeding device for a material hopper, so as to solve the problems of poor applicability and poor material flow control of the existing material hopper feeding pipe with fixed height.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a material hopper discharge device, comprising:

[0010] A fixed pipe, one end of which is used to connect with the discharge port of the material hopper;

[0011] A movable tube, one end of which is slidably connected to the other end of a fixed tube and slides along the axis of the fixed tube;

[0012] An adjustment component is connected between the fixed tube and the moving tube, and is used to drive the moving tube to slide.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The material hopper's feeding device mainly consists of a fixed pipe, a moving pipe, and an adjusting component. According to the requirements of different feeding heights, the adjusting component allows the moving pipe to slide relative to the fixed pipe, thereby adjusting the relative length between the fixed pipe and the moving pipe to the required length. This makes the material hopper's feeding device more adaptable and provides better material flow control. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below through specific embodiments:

[0021] like Figure 1 As shown in the figure, this utility model embodiment proposes a material feeding device for a material hopper, including a fixed pipe 2, a movable pipe 3, and an adjusting component 4. One end of the fixed pipe 2 is used to communicate with the feeding port of the material hopper 1; one end of the movable pipe 3 is slidably connected to the other end of the fixed pipe 2 and slides along the axial direction of the fixed pipe 2; the adjusting component 4 is connected between the fixed pipe 2 and the movable pipe 3 and is used to drive the movable pipe 3 to slide.

[0022] The material hopper's feeding device mainly consists of a fixed pipe 2, a moving pipe 3, and an adjusting component 4. According to the requirements of different feeding heights, the moving pipe 3 is slid relative to the fixed pipe 2 by adjusting the adjusting component 4, thereby adjusting the relative length between the fixed pipe 2 and the moving pipe 3 to the required length. Thus, the material hopper's feeding device has stronger adaptability and relatively better material flow control.

[0023] To better understand this solution, the following section will optimize the structure of adjustment component 4 and other components.

[0024] like Figure 1 , Figure 2 as well as Figure 3 As shown, according to another embodiment of the present invention, in the material hopper feeding device, the bottom side of the moving tube 3 is fixedly connected to a first mounting plate 5, the bottom end of the fixed tube 2 is fixedly connected to a second mounting plate 6, and the adjusting component 4 is connected between the first mounting plate 5 and the second mounting plate 6.

[0025] In this embodiment, the design of the first mounting plate 5 and the second mounting plate 6 ensures that the adjustment component 4 has sufficient mounting position, thereby ensuring that the adjustment component 4 can stably cooperate between the moving tube 3 and the fixed tube 2.

[0026] Based on the above solution:

[0027] The adjustment component 4 includes a traction rope 41 and a retraction / release part. There are two traction ropes 41 arranged symmetrically around the moving tube 3. One end of each traction rope 41 is fixedly connected to the first mounting plate 5. The retraction / release part is set on the second mounting plate 6, and the other end of each traction rope 41 passes freely through the second mounting plate 6 and is connected to the retraction / release part, which is used to retract or release the two traction ropes 41 simultaneously.

[0028] Here, the retraction and release mechanism operates to simultaneously retract or release the two traction ropes 41, thereby causing the moving tube 3 to slide inward or outward from the fixed tube 2, thus changing the relative length between the fixed tube 2 and the moving tube 3. The arrangement of the two traction ropes 41 ensures that the moving tube 3 experiences relatively balanced forces during sliding, allowing for smooth sliding.

[0029] The take-up and release section includes a take-up shaft 42 and a driver 43. There are two take-up shafts 42, both of which are rotatably connected to the second mounting plate 6. The two take-up shafts 42 are symmetrically arranged with the fixed tube 2 as the center, and the two take-up shafts 42 are connected one-to-one with the corresponding ends of the two traction ropes 41. The driver 43 is set on the second mounting plate 6 and is connected to the two take-up shafts 42 through a transmission structure. The transmission structure is used to drive the two take-up shafts 42 to rotate synchronously with the power of the driver 43.

[0030] In this embodiment, each take-up shaft 42 has a mounting block rotatably connected to both ends, which is fixedly connected to the second mounting plate 6, to stably mount the take-up shaft 42 on the second mounting plate 6. The driver 43 operates, and through the transmission structure, the two take-up shafts 42 rotate synchronously, and the two take-up shafts 42 synchronously take in or release the two traction ropes 41. Specifically, the transmission structure includes a transmission rod 44, which is connected to the driver 43, and both take-up shafts 42 are connected to the transmission rod 44 through a belt drive structure 45.

[0031] The driver 43 operates to drive the transmission rod 44 to rotate. The transmission rod 44 drives the two take-up shafts 42 to rotate through the two belt drive structures 45 respectively, and the two take-up shafts 42 rotate synchronously.

[0032] The driver 43 can be a stepper motor; the belt drive structure 45 is an existing structure, specifically including two pulleys and a belt tensioned between the two pulleys, one of the pulleys is fixedly sleeved on the transmission rod 44, and the other pulley is connected to the corresponding take-up shaft 42.

[0033] In order to make reasonable use of the power during the reeling-in or unloading process, such as Figure 4 As shown, according to another embodiment of the present invention, in the material hopper feeding device, at least one of the take-up shafts 42 is equipped with a vibrating element 7 for intermittently striking the fixed pipe 2 with the power of its rotation.

[0034] In this embodiment, a vibrating element 7 is provided on only one of the take-up shafts 42, but a vibrating element 7 can be provided on both take-up shafts 42 as needed.

[0035] When the take-up shaft 42 rotates, the power of the rotation of the take-up shaft 42 drives the vibrator 7 to intermittently strike the fixed tube 2, shaking the material adhering to the inner wall of the fixed tube 2 and the moving tube 3, ensuring that the fixed tube 2 and the moving tube 3 remain unobstructed, so as to facilitate the efficient transportation of materials.

[0036] Based on the above solution:

[0037] The vibrating element 7 includes a driving block 71 and an elastic striking part. The driving block 71 is connected to the corresponding take-up shaft 42 and has a driving inclined surface 711 on it. There are multiple elastic striking parts, all of which are fitted between the driving inclined surface 711 and the fixed tube 2. The elastic striking parts reciprocate and extend by the displacement changes generated by the movement of the driving inclined surface 711.

[0038] When the take-up shaft 42 rotates, the drive block 71 rotates synchronously with the take-up shaft 42. The displacement change of the drive inclined surface 711 caused by the movement of the drive block 71 drives the elastic striking part to reciprocate and extend, thus intermittently striking the fixed tube 2.

[0039] In this embodiment, there are two elastic striking parts; each elastic striking part includes a support block 72 and an elastic element 73. The support block 72 is fixedly connected to the second mounting plate 6 and a movable rod 74 is slidably passed through it. One end of the movable rod 74 is connected to an action part 75 for cooperating with the fixed tube 2. The elastic element 73 is connected between the action part 75 and the support block 72 and makes the other end of the movable rod 74 always slide against the driving inclined surface 711.

[0040] The support block 72 serves as a support frame. When the take-up shaft 42 rotates, the drive block 71 rotates synchronously with the take-up shaft 42, and the drive inclined surface 711 moves with the drive block 71. In conjunction with the elastic element 73, the movable rod 74 reciprocates between the drive block 71 and the fixed tube 2, causing the action part 75 to intermittently strike the fixed tube 2.

[0041] The actuating part 75 includes a striking ball and a connecting plate disposed on one end of the striking ball. An elastic element 73 is connected between the connecting plate and the support block 72. The elastic element 73 can be multiple springs connected between the connecting plate and the support block 72. In this embodiment, the number of springs is shown as two.

[0042] To prevent materials from flying everywhere during the feeding process of moving tube 3; such as Figure 1 As shown, according to another embodiment of the present invention, the material hopper feeding device wherein a flexible dust cover 8 sleeved on the bottom side of the moving tube 3 is fixedly connected to the first mounting plate 5.

[0043] The flexible dust cover 8

[0044] Flexible dust cover made of cloth 8

[0045] Multiple supporting iron rings are arranged at intervals from top to bottom to make the flexible dust cover 8

[0046] Keep it in the unfolded state when in use.

[0047] The specific operation of the material hopper's feeding device is as follows:

[0048] Start the driver 43 to make the moving tube 3 slide, and adjust the relative length between the fixed tube 2 and the moving tube 3 to the required length;

[0049] The outlet of the moving tube 3 is placed inside the receiving container, and the flexible dust cover 8

[0050] It is installed on the outside of the discharge port of the moving pipe 3;

[0051] Material can be fed from hopper 1.

[0052] During the material feeding process of the material hopper 1, the driver 43 can be rotated back and forth to make the moving tube 3 slide back and forth within a small range, and in conjunction with the reciprocating striking of the striking ball, to ensure that the material is fed efficiently.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
