Description

Technical Field

[0001] This utility model belongs to the technical field of barrel material feeding equipment, and in particular relates to a limiting mechanism for a feeding device. Background Technology

[0002] In the paint production process, barrelled raw materials need to be poured into the mixing equipment. Currently, the mainstream feeding equipment for barrelled raw materials mainly consists of a tilting device, a front clamping structure, and a lifting structure. Generally, the front clamping device fixes and holds the bottom and top surfaces of the barrel. Under the action of the lifting structure, the barrel is lifted vertically and then tilted by the tilting device. Since the barrel is fixed by both the bottom and top surfaces, it will not slip during the tilting process.

[0003] In existing technology equipment, the front clamp used to hold the material bucket mainly achieves clamping and fixing by moving the clamping structure on the top surface of the material bucket. Currently, the limiting mechanism can only be adjusted within a small range, resulting in the current feeding structure being mostly only able to fix material buckets of a single specification, thus limiting its application scope. Utility Model Content

[0005] A sleeve and a clamping rod are nested together and connected by a pin for limiting the connection. The clamping rod extends to the outside of the sleeve.

[0006] A locking ring and a locking bolt are provided. The locking bolt is threadedly connected to the portion of the clamping rod extending out of the sleeve. The locking bolt and the locking ring are nested on the clamping rod. The locking ring and the locking bolt are magnetically connected. When the feeding device limiting mechanism acts on the material barrel, the locking ring is pressed against the top of the material barrel, and the locking bolt abuts against the end face of the locking ring away from the sleeve.

[0007] Preferably, the clamping rod has a sliding cavity inside to accommodate the insertion of the clamping rod, the sliding cavity has a limiting rail, and the side wall of the clamping rod has a limiting groove adapted to it.

[0008] Preferably, the sleeve sidewall is provided with symmetrically arranged limiting holes, the clamping rod is provided with a through main limiting hole corresponding to the position of the limiting holes, and the pin completes the limiting locking by inserting into the limiting holes and the main limiting hole.

[0009] Preferably, the locking ring includes an open ring, a locking block, and a limiting locking block disposed on the inner edge of the open ring, wherein the inner wall of the open ring is provided with a limiting locking block adapted to the limiting groove.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model embodiment provides a limiting mechanism for a feeding device, such as... Figures 1-7 As shown, the limiting mechanism of the feeding device includes:

[0026] The sleeve 110 and the clamping rod 120 are nested together. A portion of the clamping rod 120 is inserted into the sleeve 110, while a portion of the clamping rod 120 extends to the outside of the sleeve 110. The portion of the clamping rod 120 located in the sleeve 110 is fixedly connected to the sleeve 110 by a pin.

[0027] A locking ring 200 and a locking bolt 300 are provided. The locking bolt 300 is threadedly connected to the portion of the clamping rod 120 extending out of the sleeve 110. The locking bolt 300 and the locking ring 200 are nested on the clamping rod 120. The locking ring 200 and the locking bolt 300 are magnetically connected. When the feeding device limiting mechanism acts on the material bucket, the locking ring 200 is pressed against the top of the material bucket, and the locking bolt 300 abuts against the end face of the locking ring 200 away from the sleeve 110. Here, the sleeve 110 is fixedly connected to the structural body of the feeding device 400 used to fix the material bucket in the prior art. This application adopts a welded connection. The feeding device 400 has the same structural principle as the prior art. This application mainly protects the limiting part, and other components are not described in detail.

[0028] The clamping rod 120 has a sliding cavity 102 inside to accommodate the insertion of the clamping rod 120. The sliding cavity 102 is provided with a limiting rail 140. The side wall of the clamping rod 120 is provided with a limiting groove 101 adapted to it. The limiting groove 101 mainly restricts the rotation of the clamping rod 120 to ensure that the locking bolt 300 can smoothly perform the torsional locking action. The side wall of the sleeve 110 is provided with symmetrically arranged limiting holes 103. The clamping rod 120 is provided with a through main limiting hole 104 corresponding to the position of the limiting holes 103. The pin 130 completes the limiting locking by inserting into the limiting holes 103 and the main limiting hole 104.

[0029] In this application, the sleeve 110 and the clamping rod 120 are connected by a pin limiting connection. When the height of the material bucket changes significantly, the sleeve 110 and the clamping rod 120 complete the large-size adjustment. The locking ring 200 and the locking bolt 300 serve as a micro-locking structure. The locking ring 200 and the locking bolt 300 are mainly used for fine-tuning. Under the action of the secondary structure, they can limit and fix more specifications of material buckets, thereby improving the feeding device's ability to fix material buckets of different specifications.

[0030] In a preferred embodiment of this invention, the sleeve 110 has symmetrically arranged limiting holes 103 on its side wall, and the clamping rod 120 has a through main limiting hole 104 corresponding to the position of the limiting holes 103. The pin 130 completes the limiting and locking by inserting into the limiting holes 103 and the main limiting hole 104. Generally, the depth of the clamping rod 120 and the sleeve 110 is adjusted before clamping the material bucket.

[0031] The locking bolt 300 includes a threaded ring 310 and a rotating handle 320. The inner wall of the threaded ring 310 is provided with threads. The portion of the clamping rod 120 extending to the outer side of the sleeve 110 is also provided with a threaded structure. The threaded ring 310 and the clamping rod 120 are threadedly engaged.

[0032] In this embodiment, the plug-in structure is faster to adjust than the spiral structure, reducing the adjustment process. The spiral structure is used as the end adjustment to avoid the defects of the plug rod not being able to be steplessly adjusted and insufficient adaptability. The length of the threaded part of the clamping rod 120 extending to the outside of the sleeve 110 needs to be greater than the spacing of the limiting plug hole 103, so that stepless adjustment can be achieved with the help of the secondary structure.

[0033] In a preferred embodiment of this invention, the end face of the screw ring 310 near the sleeve 110 is provided with a magnetic block 330, the locking ring is made of iron material that can be magnetically attracted, and the magnetic block 330 is magnetically connected to the end face of the open ring 210 away from the sleeve 110.

[0034] In this embodiment, the end face of the screw ring 310 near the sleeve 110 is provided with a receiving cavity for accommodating the magnetic block 330, and the magnetic block 330 is fixed in the receiving cavity by an embedded method;

[0035] The locking ring 200 includes an open ring 210, a locking block 220, and a limiting locking block 230 disposed on the inner edge of the open ring 210. The inner wall of the open ring 210 is provided with a limiting locking block 230 that is adapted to the limiting slide groove 101.

[0036] The locking bolt 300 is magnetically connected to the open ring 210 by the magnetic block 330. When the locking bolt 300 rotates, the limiting block 230 on the open ring 210 restricts the rotation of the open ring 210. When the torque force is greater than the magnetic force, the locking bolt 300 will move out of position. Here, the magnetic connection mainly helps the locking ring 200 to attach to the locking bolt 300 when the sleeve 110 and the clamping rod 120 are inserted and adjusted. In the subsequent process, the locking ring 200 can be held against the material barrel by the locking action of the locking bolt 300.

[0037] The locking block 220 mainly consists of a front buckle at the front end for fixing the material bucket and a support seat on the side near the clamping rod 120. The support seat adopts a trapezoidal structure to help the open ring 210 directly transmit pressure to the clamping rod 120.

[0038] When the structure of the material hopper changes, the locking ring 200 can be replaced entirely to ensure that the front buckle of the corresponding specification can be used to fix the appropriate material hopper.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
