Description

Technical Field

[0001] This utility model relates to the field of hopper technology, and in particular to a material loading funnel. Background Technology

[0002] A typical loading and unloading hopper consists of a cylindrical hopper body and a cover hinged to the lower end of the hopper body. The cover and the hopper body are locked together by a latch. When the hopper is filled with small materials such as aluminum blocks, if the gap between the latch and the latch is large, the cover and the hopper will not close tightly. The cover will wobble and create gaps between itself and the hopper, making it easy for the aluminum blocks to get stuck in the gaps or leak out, affecting production efficiency.

[0003] Therefore, it is necessary to design a loading funnel with minimal shaking of the lid when it is closed.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model discloses a feeding funnel to solve the problem of material leakage and reduced production efficiency caused by gaps between the cover and the hopper when the cover is closed.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A feeding funnel, comprising: a funnel body, which is a hollow structure with openings at the top and bottom; a cover, hinged to the lower end of the funnel body, with a latch at the upper end; and a switch assembly, comprising: a rotating shaft, rotatably passing through the side of the funnel body; a gear, fixed to one end of the rotating shaft located inside the funnel body; and a slider, slidably disposed on the inner wall of the funnel body, with its upper end meshing with the gear and a locking tongue at the end away from the rotating shaft; wherein, rotating the rotating shaft drives the gear to rotate, the gear drives the slider to slide, and the locking tongue slides into or out of the latch to close or open the cover.

[0008] A further technical solution is that a guide cylinder is provided on the outside of the bucket body, and the rotating shaft passes through the guide cylinder.

[0009] A further technical solution is that milled flat rods are provided at both ends of the rotating shaft. Two flat surfaces are symmetrically milled on the outer side of the milled flat rods, and the outer side of the portion of the milled flat rods away from the center of the rotating shaft has threads. The gear is sleeved on the milled flat rod located inside the bucket. A first nut is screwed into the milled flat rod to fix the gear to the rotating shaft. The switch assembly also includes a handle. The handle is provided on the milled flat rod located outside the bucket. A second nut is screwed into the milled flat rod to fix the handle to the rotating shaft.

[0010] A further technical solution is that a horizontally fixed slide rail is provided on the inner wall of the bucket, and the slider is engaged with the slide rail and can slide along the slide rail.

[0011] A further technical solution is that a fixed cover is fixed inside the bucket body, and the cover is placed on the outside of the buckle, slider, rotating shaft and gear.

[0012] A further technical solution is that when the handle is rotated to the closed position of the cover, the slider abuts against the latch; when the handle is rotated to the open position of the cover, the slider abuts against the cover.

[0013] A further technical solution is that a rack is provided at the upper end of the slider, and the rack meshes with the gear.

[0014] A further technical solution is that a sleeve is fitted on the outer side of the rotating shaft between the gear and the inner wall of the bucket.

[0015] A further technical solution is that a first nail portion is provided on the side of the handle away from the bucket body, and a second nail portion is also provided on the outside of the bucket body located on the switch assembly, with an elastic element provided between the first nail portion and the second nail portion.

[0016] A further technical solution is that the bucket body includes a first cylinder, a variable diameter cylinder, and a second cylinder connected sequentially from top to bottom, wherein the inner diameter of the upper end of the variable diameter cylinder is larger than the inner diameter of the lower end.

[0017] The beneficial effects of this utility model embodiment are as follows:

[0018] (a) The material funnel of this utility model rotates the cover relative to the hopper to the closed position. By rotating the shaft, the shaft drives the gear to rotate, the gear drives the slider to slide, and the locking tongue slides into or out of the latch to close or open the cover. Since the locking tongue and the latch can achieve a clearance fit, the swaying space between the cover and the hopper is small, which is suitable for loading small materials such as aluminum blocks into the hopper.

[0019] (ii) Furthermore, a first nail is provided on the side of the handle away from the hopper, and a second nail is provided on the outside of the hopper located on the switch assembly. An elastic element is provided between the first nail and the second nail, and the elastic element always provides tension to ensure that the handle is in the closed position.

[0031] Example:

[0032] This embodiment discloses a charging funnel.

[0033] like Figure 1 and Figure 2 As shown, the loading hopper includes a hopper body 1, a cover body 2, and a switch assembly.

[0034] like Figure 1 and Figure 2 As shown, the hopper 1 is a hollow structure with openings at the top and bottom. The cover 2 is hinged to the lower end of the hopper 1, and a latch 21 is provided in the middle of one side of the upper end. For example, the outer sides of the hopper 1 and the cover 2, opposite to the position of the latch 21, are connected by a hinge 22, so that when the cover 2 is opened relative to the hopper 1, no gap is formed between the cover 2 and the hopper 1 that would allow the aluminum block to get stuck.

[0035] like Figure 3 and Figure 4 As shown, the switch assembly includes a rotating shaft 3, a gear 4, and a slider 6.

[0036] The rotating shaft 3 can rotatably pass through the side of the bucket body 1. For example... Figure 4 As shown, for example, a guide cylinder 11 is provided on the outside of the bucket body 1, and the rotating shaft 3 passes through the guide cylinder 11. The guide cylinder 11 is perpendicular to the surface of the bucket body 1, so that the rotating shaft 3 remains circumferentially stable when it rotates.

[0037] like Figures 4-6As shown, gear 4 is fixed to one end of the rotating shaft 3 located inside the bucket body 1. For example, milled flat rods 31 are provided at both ends of the rotating shaft 3. Two flat surfaces are symmetrically milled on the outer side of the milled flat rods 31, and the outer side of the portion of the milled flat rods 31 away from the center of the rotating shaft 3 has threads 311. Gear 4 is sleeved on the milled flat rods 31 located inside the bucket body 1, and the first nut 32 is screwed into the milled flat rods 31 to fix gear 4 to the rotating shaft 3.

[0038] like Figure 3 , Figure 4 and Figure 7 As shown, the slider 6 is slidably disposed on the inner wall of the bucket body 1, with its upper end meshing with the gear 4, and a locking tongue 61 disposed at the end away from the rotating shaft 3. For example, a horizontally fixed slide rail 5 is mounted on the inner wall of the bucket body 1, and the slider 6 is engaged with the slide rail 5 and can slide along the slide rail 5. A rack 62 is disposed at the upper end of the slider 6, and the rack 62 meshes with the gear 4. The locking tongue 61 is integrally formed with the slider 6, and the locking tongue 61 is in clearance fit with the internal part of the latch 21.

[0039] Among them, the rotating shaft 3 drives the gear 4 to rotate, the gear 4 drives the slider 6 to slide, and the locking tongue 61 slides into or out of the latch 21 to close or open the cover 2.

[0040] like Figure 3 and Figure 4 As shown, the switch assembly further includes a handle 7, which is sleeved on the milling rod 31 located outside the bucket body 1. The second nut 33 is screwed into the milling rod 31 to fix the handle 7 to the rotating shaft 3, so that the operator can hold the handle 7 and rotate the rotating shaft 3.

[0041] like Figure 3 and Figure 4 As shown, further, the bucket body 1 has an internal fixed cover 9, which covers the outside of the latch 21, slider 6, rotating shaft 3 and gear 4 to prevent the aluminum block from getting stuck between the gears 4 or into the latch 21, thus affecting the operation of the switch assembly.

[0042] like Figure 3 As shown, further, when the handle 7 is rotated to the closed position of the cover 2, since the width of the slider 6 is greater than the internal width of the latch 21, the slider 6 abuts against the latch 21, restricting the slider 6 from moving closer to the latch 21. When the handle 7 is rotated to the open position of the cover 2, the slider 6 abuts against the cover 9, restricting the slider 6 from moving away from the latch 21.

[0043] like Figure 4 As shown, furthermore, a sleeve 34 is fitted on the outer side of the rotating shaft 3 between the gear 4 and the inner wall of the bucket body 1 to reduce the axial shaking of the rotating shaft 3.

[0044] like Figure 3 and Figure 4As shown, a first nail portion 71 is provided on the side of the handle 7 away from the bucket body 1, and a second nail portion 15 is also provided on the outside of the switch assembly on the bucket body 1. An elastic element 8 is provided between the first nail portion 71 and the second nail portion 15. The elastic element 8 always provides tension to ensure that the handle 7 is in the closed cover 2 position.

[0045] like Figure 1 and Figure 2 As shown, furthermore, lifting lugs 16 are symmetrically arranged on both sides of the bucket body 1, which facilitates lifting the bucket body 1 for movement and unloading.

[0046] like Figure 1 and Figure 2 As shown, the bucket body 1 further includes a first cylinder 12, a variable diameter cylinder 13 and a second cylinder 14 connected sequentially from top to bottom. The inner diameter of the upper end of the variable diameter cylinder 13 is larger than the inner diameter of the lower end, which facilitates the internal aluminum block to slide out from the bucket body 1.

[0047] In this embodiment, the cover 2 is rotated relative to the hopper to the closed position. By rotating the shaft 3, the shaft 3 drives the gear 4 to rotate, and the gear 4 drives the slider 6 to slide. The locking tongue 61 slides into or out of the latch 21 to close or open the cover 2. Since the locking tongue 61 and the latch 21 can achieve a clearance fit, the swaying space between the cover 2 and the hopper is small, which is suitable for loading small materials such as aluminum blocks into the hopper.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
