Abstract
Description
Technical Field
[0001] This utility model relates to a fixing device, and more particularly to a limiting tube fixing device that can be quickly positioned and adjusted. Background Technology
[0002] In the tobacco industry, siloed feeders and steep-angle conveyor belts are widely used to feed materials to electronic scales. These scales employ flow control tubes to precisely control their flow rate. However, different tobacco leaf blends and grades require different process parameters, resulting in varying flow rates. As the flow rate changes, if it increases from low to high, an improperly positioned flow control tube in the feed hopper can lead to insufficient flow, causing material interruption and affecting product quality. Conversely, if the flow rate decreases from high to low, an improperly positioned flow control tube can cause frequent start-ups and shutdowns of the upstream equipment, resulting in continuous tumbling and crushing of the material at the equipment joints, severely impacting product quality. Current technologies generally employ two methods to address this issue: one is to adjust the flow control tube position according to different grades; the other is to fix the flow control tube position at a suitable intermediate position without further adjustment. Since each tobacco production unit produces a large number of grades, the first method is time-consuming and labor-intensive, and often results in signal loss after simultaneous adjustments on both sides; the second method significantly impacts product quality, making batch stability unreliable.
[0003] Meanwhile, during production and equipment maintenance, the material level gauge tube in the hopper is easily touched by relevant personnel, causing changes in its angle and position, which affects the transmission and sensing of the material level signal. However, the current installation and fixing methods often make it difficult to match the positions on both sides. If there is a slight error, the gauge tube will not receive a signal, which seriously affects production efficiency. Utility Model Content

Detailed Implementation
[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0021] Embodiments of this utility model: such as Figures 1-5 As shown, a quick-positioning and adjustable limiting tube fixing device includes a mounting bracket 1, a clamping adjustment device 2, a fastening mounting device 3, and a connecting seat 4. The clamping adjustment device 2 is mounted on the mounting bracket 1, and the fastening mounting device 3 is connected to the clamping adjustment device 2 through the connecting seat 4. The limiting tube is mounted on the fastening mounting device 3.
[0022] Specifically, the mounting bracket 1 includes a rod-shaped portion 11 and a first limiting tooth 12. The cross-sectional shape of the rod-shaped portion 11 is rectangular, and a plurality of first limiting teeth 12 are evenly distributed on a set of opposite sidewalls of the rod-shaped portion 11.
[0023] The rod-shaped part 11 is fixed on the existing equipment frame. The rod-shaped part 11 is arranged vertically. The first limiting tooth 12 is used to interact with the clamping adjustment device 2 and plays a role in accurately limiting the clamping adjustment device 2.
[0024] A scale mark 13 is provided on one side of the rod-shaped part 11, and the scale mark 13 is arranged along the length of the rod-shaped part 11. The height position of the clamping adjustment device 2 can be accurately determined by the scale mark 13, thereby determining the height of the limiting tube on the fastening mounting device 3.
[0025] Two sets of the device described in this application are installed on site, each with a measuring tube. If one measuring tube is accidentally touched during operation, its height may change. This can be quickly adjusted to the same height as the other measuring tube using the scale mark 13. In existing technologies, the lack of a scale mark necessitates repeated measurements and adjustments by personnel to ensure the two measuring tubes are at the same height.
[0026] Furthermore, the clamping adjustment device 2 includes a first end plate 21, a second end plate 22, a connecting plate 23, and a movable clamping plate 24. The first end plate 21 and the second end plate 22 are parallel and opposite to each other. The two ends of the connecting plate 23 are fixedly connected to the first end plate 21 and the second end plate 22, respectively. The movable clamping plate 24 is installed on the first end plate 21. The movable clamping plate 24 and the second end plate 22 are both provided with second limiting teeth 25 on their opposite sides.
[0027] In this embodiment, the first end plate 21, the second end plate 22, and the connecting plate 23 are integrally formed, forming a "U" shape, with the opening facing horizontally during use. The first end plate 21 and the second end plate 22 are of the same specifications. The movable clamping plate 24 cooperates with the second end plate 22 to clamp the rod-shaped part 11. With the cooperation of the first limiting tooth 12 and the second limiting tooth 25, the clamping adjustment device 2 is positioned on the mounting bracket 1. The position of the clamping adjustment device 2 relative to the mounting bracket 1 will not change when the operator does not adjust it. The tooth shape and tooth spacing of the second limiting tooth 25 are the same as those of the first limiting tooth 12.
[0028] A first through hole 211 is provided on the first end plate 21, and a connecting rod 26 is fixedly provided on the movable clamping plate 24. The connecting rod 26 passes through the first through hole 211 through the first end plate 21 and is fixedly connected to the handle 27.
[0029] The movable clamp 24 is located between the first end plate 21 and the second end plate 22. In this embodiment, the handle 27 is a round handle, and the handle 27 and the connecting rod 26 are connected by threads, which facilitates installation and disassembly.
[0030] Two first protrusions 212 are fixedly provided on the inner wall of the first end plate 21, and two second protrusions 241 are fixedly provided on the movable clamping plate 24. The two second protrusions 241 are opposite to the two first protrusions 212. It also includes two springs 28. One end of the two springs 28 is respectively sleeved and fixedly connected to the two first protrusions 212, and the other end of the two springs 28 is respectively sleeved and fixedly connected to the two second protrusions 241.
[0031] Two springs 28 are used to provide elastic force. The springs 28 apply a pushing force to the movable clamping plate 24, causing the movable clamping plate 24 to move towards the second end plate 22, thereby cooperating with the second end plate 22 to make the second limiting tooth 25 engage with the first limiting tooth 12 on the rod-shaped part 11.
[0032] Furthermore, the connecting seat 4 is an L-shaped connecting seat composed of a vertical plate and a horizontal plate. The vertical plate of the connecting seat 4 is fixedly connected to the outer wall of the connecting plate 23, and the fastening installation device 3 is fixed on the horizontal plate of the connecting seat 4.
[0033] The connecting seat 4 and the connecting plate 23 can be fixed by adhesive or welding. Preferably, the connecting seat 4 and the fastening mounting device 3 are fixed by bolts.
[0034] Furthermore, the fastening and mounting device 3 includes a limiting tube fastening and mounting bracket 31, a limiting tube mounting hole 32 is provided on the limiting tube fastening and mounting bracket 31, a clamping groove 33 is provided on the limiting tube mounting hole 32, and a coaxial second through hole 34 and a threaded hole 35 are provided on the limiting tube fastening and mounting bracket 31.
[0035] The clamping groove 33 separates the upper part of the limiting tube fastening mounting bracket 31 into two separate parts. The second through hole 34 and the threaded hole 35 are located on both sides of the clamping groove 33. The limiting tube is installed in the limiting tube mounting hole 32. A locking bolt is passed through the second through hole 34 and threadedly connected to the threaded hole 35. Tightening the locking bolt can make the limiting tube mounting hole 32 hold the limiting tube tightly, ensuring that the limiting tube is securely fastened without loosening. It should be noted that the limiting tube is an existing product, and this application does not protect the structure of the limiting tube, nor is the limiting tube shown in the figure.
[0036] The working principle of this utility model is as follows: When the height of the measuring tube needs to be adjusted, simply pull the handle 27 to move the movable clamping plate 24 away from the rod-shaped part 11, increasing the distance between the movable clamping plate 24 and the second end plate 22. This causes the second limiting teeth 25 on the movable clamping plate 24 and the second end plate 22 to disengage from the first limiting teeth 12 on the rod-shaped part 11. At this time, the clamping adjustment device 2 can be moved up or down. During the adjustment process, the scale markings 13 on the rod-shaped part 11 can be used to achieve rapid adjustment. After adjusting to the appropriate position, release the handle 27. Under the elastic force of the two springs 28, the movable clamping plate 24 moves closer to the second end plate 22, and the second limiting teeth 25 engage with the first limiting teeth 12. The springs provide clamping force to maintain the fixed position, achieving rapid adjustment and rapid positioning. When the measuring tube needs to be replaced, loosen the locking bolt, replace the measuring tube, and tighten the locking bolt after replacement.
[0037] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
