Description

Technical Field

[0001] This application relates to the technical field of valve port scale placement devices, and in particular to a screw conveyor valve port scale. Background Technology

[0002] The screw conveyor valve scale is an automated quantitative device widely used in the packaging of powdered materials. The core of this equipment lies in utilizing the rotational motion of a screw conveyor to stably and continuously push powdered materials such as cement, flour, mineral powder, and chemical raw materials from the storage silo to the discharge port.

[0003] In existing technologies, a typical auger valve weigher structure mainly includes a frame, a drive unit, an auger, a weighing sensor, and a platform for holding the empty packaging bags. The operator places the valve opening of the empty packaging bag over the lower end of the auger's outlet and then places the bag stably on the platform for support. The drive unit then starts, rotating the auger to fill the packaging bag with material. The weighing system monitors weight changes in real time during the filling process, typically employing a two-stage "fast-slow" feeding mode: rapid feeding at the initial stage to improve efficiency, and switching to slow, precise feeding as the target weight approaches, ensuring the final metering accuracy meets process requirements.

[0004] However, the relative distance between the platform used to support the packaging bags and the auger outlet is usually fixed and cannot be adjusted. This fixed structure causes many operational inconveniences and limitations. For non-standard sized packaging bags, operators need to exert considerable effort to adjust or support them, increasing the difficulty of operation. Secondly, during the loading and unloading process, the fixed space restricts the operator's range of motion, making processes such as bagging and bag removal cramped, which not only affects the overall packaging efficiency but also increases the labor intensity of operators in the long run. Utility Model Content

[0005] To facilitate the loading and unloading of packaging bags, this application provides a screw conveyor valve scale.

[0006] The auger valve port scale provided in this application adopts the following technical solution: A screw conveyor valve scale includes a frame, a mounting bracket, side guards, and a placement platform, wherein: The frame is equipped with a discharge port; The mounting bracket is installed on the frame; The side guard is mounted on the mounting frame and moves relative to the mounting frame in the horizontal direction via a drive unit; The placement platform is mounted on the mounting frame, and the vertical position of the placement platform on the mounting frame can be adjusted.

[0007] Optionally, the mounting frame is U-shaped and includes a vertical plate and wing plates. A pair of wing plates are provided, located on both sides of the vertical plate.

[0008] Optionally, the drive unit is a telescopic rod, which is mounted on the mounting frame, and the push rod of the telescopic rod passes through the mounting frame, with the push rod end of the telescopic rod connected to the side stop.

[0009] Optionally, the side baffle includes a rear baffle and side baffles, wherein the rear baffle is vertically located near the mounting bracket, and a pair of side baffles are arranged in parallel, with the pair of side baffles respectively located on both sides of the rear baffle.

[0010] Optionally, the side baffle is provided with a guide plate at a position away from the rear baffle, and the spacing between adjacent guide plates gradually increases along the direction from near the rear baffle to away from the rear baffle.

[0011] Optionally, the placement platform includes a placement rack and placement rollers, wherein: The placement is mounted on the mounting frame; The placement rollers are rotatably mounted on the placement frame, and multiple rollers are distributed along the direction from near the mounting frame to away from the placement frame.

[0012] Optionally, the placement rack is provided with a pair of mounting plates at one end near the mounting frame, and a positioning plate that contacts the vertical plate of the mounting plate is connected between the pair of mounting plates; A positioning rod is provided through the pair of mounting plates; The mounting bracket has multiple positioning grooves along the vertical direction on its wing plate for placing the positioning rod.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the positioning rod and multiple positioning grooves, the height of the placement platform can be flexibly and stably adjusted in the vertical direction, so that it can accurately adapt to packaging bags of different heights and solve the compatibility problem caused by fixed spacing; 2. The side baffle integrates positioning and ejection functions and is precisely driven by a telescopic rod. Combined with the automatic guiding function of the guide plate, it ensures the stability of the packaging bag during the filling process and the smoothness of ejection, effectively improving the reliability and accuracy of operation. 3. The rolling support surface formed by the placement rollers significantly reduces the friction when the packaging bag moves, which not only makes the pushing action easier and protects the packaging bag, but also, in conjunction with the adjustable side guards, enables fast and smooth loading and unloading, greatly improving the overall efficiency of the packaging operation.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0019] This application discloses a screw conveyor valve scale.

[0020] A screw conveyor valve scale includes a frame 1, a mounting frame 2, a side baffle 3, and a placement platform 4. The frame 1 has a discharge port 11. The mounting frame 2 is fixed to the frame 1. The side baffle 3 is mounted on the mounting frame 2 and connected to a drive unit 5, which can drive the side baffle 3 to move horizontally relative to the mounting frame 2. The placement platform 4 is also mounted on the mounting frame 2, and its vertical position on the mounting frame 2 is adjustable.

[0021] During operation, the operator first adjusts the vertical position of the placement platform 4 on the mounting frame 2 according to the height of the bag to be packaged, ensuring proper support for the bag after it is attached to the discharge port 11. Then, based on the width of the bag, the operator controls the side baffle 3 to move horizontally, allowing it to contact and stabilize the bag from the side, preventing it from shaking or tipping over during filling. After these adjustments are completed, the normal material filling process can begin.

[0022] The mounting bracket 2 has an overall U-shaped structure. The mounting bracket 2 consists of a vertical plate 21 and a pair of wing plates 22. The pair of wing plates 22 are respectively located on the left and right sides of the vertical plate 21.

[0023] The U-shaped mounting frame 2 is stably connected to the frame 1 through its vertical plate 21, providing support for the main structure.

[0024] The side baffle 3 is configured to move horizontally along a direction perpendicular to the vertical plate 21 of the mounting frame 2. This side baffle 3 serves a positioning function during the bag positioning stage and performs the function of pushing out the bag after filling. The drive unit 5 is in the form of a telescopic rod, the body of which is fixedly mounted on the vertical plate 21 of the mounting frame 2. The push rod of the telescopic rod horizontally penetrates the vertical plate 21 of the mounting frame 2, and the end of the push rod is directly connected to the side baffle 3. In this embodiment, the telescopic rod is a cylinder.

[0025] During operation, when an empty packaging bag needs to be placed, the telescopic rod is retracted, and the side baffle 3 is in the rear position, providing ample operating space for the operator. Once the packaging bag is in place, the telescopic rod pushes the side baffle 3 forward, causing it to contact the side of the packaging bag and complete its positioning. During the filling process, the side baffle 3 remains in position to ensure the stability of the packaging bag. After filling is complete, the telescopic rod pushes the side baffle 3 forward again, at which point the side baffle 3 pushes the fully filled packaging bag forward, completing the unloading action.

[0026] The side baffle 3 consists of a rear baffle 31 and a pair of side baffles 32. The rear baffle 31 is in a vertical position and is positioned near the vertical plate 21 of the mounting bracket 2. The pair of side baffles 32 are arranged parallel to each other and are fixed to the left and right edges of the rear baffle 31, respectively.

[0027] During operation, as the telescopic rod pushes the rear baffle 31 forward, a pair of side baffles 32 fixed to both sides of the rear baffle 31 move forward synchronously. In the positioning phase, the two side baffles 32 contact and straighten the packaging bag from both sides; in the pushing phase, the two side baffles 32 continue to move forward synchronously, jointly pushing the fully loaded packaging bag forward until it is completely removed from the working area. Throughout the entire process, the sides of the packaging bag are always constrained and guided by the parallel side baffles 32.

[0028] On a pair of side baffles 32, guide plates 33 are respectively provided at their front ends away from the rear baffle 31. The distance between the two guide plates 33 gradually increases from the root near the rear baffle 31 to the end away from the rear baffle 31.

[0029] The funnel-shaped channel formed between the guide plates 33 can automatically guide the packaging bag, which may be slightly tilted, when the side baffle 3 moves forward.

[0030] During operation, when the side baffle 3 moves forward to perform positioning or ejection functions, the guide plate 33 located at the front end of the side baffle 32 will first contact the packaging bag. If the packaging bag is slightly misaligned at this time, its body will first contact the inner surface of the inclined guide plate 33. As the side baffle 3 continues to move forward, the inclined surface of the guide plate 33 will gradually guide the packaging bag to the correct position between the two side baffles 32. During ejection, the same guiding structure also prevents the packaging bag from getting stuck with the side baffle 32 during movement, ensuring a smooth ejection action.

[0031] The placement platform 4 consists of a placement frame 41 and a plurality of placement rollers 42. The placement frame 41 is mounted on the mounting frame 2. The placement rollers 42 are rotatably mounted on the placement frame 41, and these placement rollers 42 are arranged along a direction from near the mounting frame 2 to away from the mounting frame 2, and there are a plurality of them distributed in this direction.

[0032] During operation, empty packaging bags are placed on a platform consisting of multiple placement rollers 42. When the side baffle 3 pushes the packaging bag, the bottom of the bag contacts the placement rollers 42, causing the rollers 42 to rotate. The multiple placement rollers 42 are distributed along the direction of bag movement, collectively supporting the bag and ensuring even force distribution during movement, preventing localized deformation or jamming. Throughout the entire filling and ejection process, the placement rollers 42 consistently assist the packaging bag in horizontal displacement through rolling.

[0033] A pair of mounting plates 43 are fixedly mounted on the placement frame 41 at one end near the mounting frame 2. A positioning plate 44 is connected between the pair of mounting plates 43, and the positioning plate 44 is in contact with the surface of the vertical plate 21 of the mounting frame 2. A positioning rod 45 is provided through the pair of positioning plates 44. Multiple sets of positioning grooves 23 are formed on the wing plate 22 of the mounting frame 2 along the vertical direction. These positioning grooves 23 are used to support and fix the two ends of the positioning rod 45.

[0034] The positioning rod 45, in conjunction with the positioning grooves 23 at different heights, achieves mechanical fixing and adjustment of the height of the placement platform 4. When adjusting the height of the placement platform 4, the operator first lifts the placement frame 41 upwards, disengaging the positioning rod 45 from its current positioning groove 23. Then, the placement frame 41 is adjusted to the desired height, aligning both ends of the positioning rod 45 with the corresponding level of positioning groove 23. Finally, the positioning rod 45 is smoothly placed into the pair of positioning grooves 23, at which point the placement frame 41 and its placement roller 42 are fixed at the new working height. The entire adjustment process requires no tools and is simple and quick.

[0035] The implementation principle of the auger valve scale according to this application embodiment is as follows: During operation, firstly, according to the height of the packaging bag, the positioning rod 45 of the placement frame 41 is removed from the current positioning groove 23 on the wing plate 22 of the mounting frame 2. After adjusting the placement frame 41 to a suitable height, the positioning rod 45 is put back into the positioning groove 23 of the corresponding height to complete the fixation. Then, the empty packaging bag is placed on the multiple placement rollers 42 of the placement frame 41, so that its bag mouth is aligned with the discharge port 11. At this time, the telescopic rod on the mounting frame 2 is activated, and its push rod extends, pushing the side baffle 3, which is composed of the rear baffle 31 and a pair of side baffles 32, to move horizontally in a direction perpendicular to the mounting frame 2. The guide plate 33 at the front end of the side baffle 32 first contacts the bag body, and automatically guides the packaging bag with its gradually widening gap. Then, the side baffle 32 continues to move forward to the predetermined position, clamping the packaging bag from both sides to complete the positioning. After the filling is completed, the telescopic rod pushes the side baffle 3 forward again, smoothly pushing the packaging bag filled with material away from the placement rollers 42 to complete the unloading.

[0036] 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.
