Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically a screening machine. Background Technology

[0002] In industrial production and daily life, foamed balls are widely used in packaging protection, toy manufacturing, and filling materials. After the foamed balls are produced and processed, they need to be sorted by specifications using a specialized screening machine to classify and group foamed balls of different diameters to meet the needs of subsequent use in different scenarios. The screening machine has become one of the key pieces of equipment in the foamed ball production process to ensure product quality and compatibility.

[0003] In existing technologies, the screening structure of screening machines is a fixed design, and it can only accommodate a single specification of foamed balls. When screening different batches or different diameters of foamed balls, it is often necessary to disassemble and replace the entire screening assembly. This not only involves cumbersome operations and consumes a lot of time, causing frequent interruptions in the production process, but also requires additional investment in purchasing multiple sets of assemblies to accommodate different specifications, increasing production and operating costs. Furthermore, during the screening process, foamed balls tend to accumulate in the screening channel, preventing subsequent materials from sliding smoothly, causing the screening process to stall and reducing screening efficiency.

[0004] Therefore, we propose a screening machine to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a screening machine to solve the problems mentioned in the background art, such as the inconvenience of adjusting and screening foamed balls of different specifications, the easy accumulation and blockage of foamed balls during the screening process, causing the screening process to be blocked and reducing screening efficiency.

[0006] This utility model provides the following technical solution: a screening machine, including a screening machine body, a vibrating feeding plate installed on the screening machine body, a discharge pipe connected to the end of the vibrating feeding plate, a screening channel installed on the screening machine body, two fixed plates fixed on the screening channel, a partition plate one movably installed on one of the fixed plates, a partition plate two fixed on the other fixed plate, an adjustment component installed on the screening channel, and a toggle component provided on the partition plate two.

[0007] Preferably, the adjustment assembly includes a mounting plate fixed to the fixed plate, a fixing rod fixed to the mounting plate, and a partition plate rotatably connected to the fixing rod.

[0008] Preferably, a connecting plate is fixed to the side wall of the first partition plate, an installation block is fixed to the end of the connecting plate, a T-shaped insert rod slides inside the installation block, a spring is sleeved on the outer ring of the T-shaped insert rod, a pull ring is fixed on the T-shaped insert rod, and multiple insertion holes are opened on the screening channel, and the T-shaped insert rod is inserted into the insertion holes.

[0009] Preferably, one end of the spring is fixedly connected to the T-shaped insert, and the other end of the spring is fixedly connected to the mounting block.

[0010] Preferably, the actuating assembly includes two support blocks symmetrically fixed on the fixed plate, one of the support blocks has a motor fixed to its side wall, the output end of the motor has a lead screw fixed to it, the lead screw is rotatably connected to the two support blocks, the outer ring of the lead screw is threaded with a slider, a lever is fixed on the slider, and a buffer ball is fixed to the bottom surface of the lever.

[0011] Preferably, a limiting block is fixed to the bottom surface of the slider, and a sliding groove is provided on the fixing plate, with the limiting block slidably connected to the sliding groove.

[0012] This utility model has the following beneficial effects: 1. This screening machine effectively improves upon the limitations of existing screening machines, which have fixed screening structures and limited compatibility with a single specification. It enhances the adaptability and versatility for screening foamed balls of different specifications. When screening foamed balls of different batches and diameters, there is no need to disassemble and replace the entire screening assembly. The guide channel width can be flexibly adjusted through simple operation, significantly simplifying the specification switching process, avoiding frequent production interruptions due to component replacement, reducing downtime, and eliminating the need for additional investment in multiple sets of components to adapt to different specifications, thus lowering equipment investment and operating costs for multi-specification screening. Simultaneously, it ensures accuracy during the screening process, preventing small-sized foamed balls from getting stuck or large-sized foamed balls from accidentally entering small-diameter feed pipes. This achieves efficient grading and screening of foamed balls of various specifications, and the entire screening process eliminates the need for manual sorting, further improving screening efficiency and operational convenience.

[0013] 2. This screening machine specifically addresses the problem of foamed balls accumulating in the screening channel during the screening process in existing screening machines. It effectively prevents subsequent materials from obstructing the smooth flow of materials and causing screening process blockages due to accumulation, ensuring a continuous and smooth screening process and stable screening efficiency. This solves the problem of reduced screening efficiency caused by accumulation in existing equipment. Simultaneously, during the process of clearing accumulated foamed balls, it effectively prevents surface damage and deformation caused by mutual compression, friction, or hard contact with the clearing components, ensuring the product quality of the foamed balls, improving the stability and reliability of the screening operation, further optimizing overall performance, and better meeting the diverse needs of foamed ball screening in actual production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: This embodiment aims to address the problems of poor adaptability and low versatility of traditional screening machines for screening foamed balls of different sizes. Please refer to [link / reference]. Figure 1 - Figure 4A screening machine includes a screening machine body 1, a vibrating feeding plate 2 installed on the screening machine body 1, a discharge pipe 3 connected to the end of the vibrating feeding plate 2, a screening channel 4 installed on the screening machine body 1, two fixing plates 5 fixed on the screening channel 4, a partition plate 6 movably installed on one of the fixing plates 5, a partition plate 8 fixed on the other fixing plate 5, and an adjustment component 7 installed on the screening channel 4.

[0023] The adjustment assembly 7 includes a mounting plate 71 fixed on the fixing plate 5, a fixing rod 72 fixed on the mounting plate 71, a partition plate 6 rotatably connected to the fixing rod 72, a connecting plate 73 fixed on the side wall of the partition plate 6, a mounting block 74 fixed on the end of the connecting plate 73, a T-shaped insert 75 sliding inside the mounting block 74, a spring 76 sleeved on the outer ring of the T-shaped insert 75, a pull ring 77 fixed on the T-shaped insert 75, a plurality of insertion holes 78 opened on the screening channel 4, the T-shaped insert 75 being inserted into the insertion holes 78, one end of the spring 76 being fixedly connected to the T-shaped insert 75, and the other end of the spring 76 being fixedly connected to the mounting block 74.

[0024] In this embodiment: First, the foamed balls to be screened are poured into the vibrating feeding plate 2 in batches. The vibrating feeding plate 2 breaks the disordered stacking state of the foamed balls through high-frequency low-amplitude vibration and conveys them one by one and evenly to the discharge pipe 3. The discharge pipe 3, relying on its own guiding structure, further ensures that the foamed balls are introduced into the screening channel 4 at a stable speed.

[0025] It should be noted that screening channel 4 is existing technology. Multiple distribution pipes are arranged sequentially along the sliding direction of the foamed balls, and each distribution pipe is separated by an auxiliary partition. The diameter of the distribution pipes increases sequentially according to the size of the corresponding foamed balls, ensuring that foamed balls of different sizes can enter the corresponding distribution pipes. The arrangement logic of the distribution pipes will be briefly explained here and will not be elaborated on later.

[0026] Since the bearing surface of the screening channel 4 is inclined at a preset angle to the horizontal plane, and the partition plate 6 and the partition plate 8 are fixed vertically on the bearing surface of the screening channel 4, forming a guide channel that is consistent with the inclination direction of the screening channel 4, when the foaming ball enters the screening channel 4, it slides down the inclined surface at a stable speed under the combined action of its own gravity and the guide channel.

[0027] During the sliding process, the operator can flexibly adjust the position of the partition plate 6 by adjusting component 7 according to the actual size difference of the foam balls to be screened, so as to adapt to the screening requirements of different batches of foam balls. In specific operation, the operator holds and pulls the pull ring 77 at the end of the T-shaped insert 75, so that the T-shaped insert 75 moves axially along the sliding hole of the mounting block 74. During this process, the T-shaped insert 75 will overcome the elastic tension of the spring 76 and gradually disengage from the preset insertion hole 78 on the side wall of the screening channel 4. When the T-shaped insert 75 is completely pulled out of the insertion hole 78, the partition plate 6 is released from the fixed constraint and can be adjusted around the rotation connection point between it and the fixed rod 72. The operator rotates the partition plate 6 to a suitable angle according to the diameter of the target foam ball. The width of the guide channel formed between the adjusted partition plate 6 and the partition plate 8 is just enough to allow the target size foam ball to pass smoothly, while blocking foam balls larger than the size, ensuring that the corresponding size foam ball can be accurately aligned with the inlet of the front distribution pipe. After the angle is adjusted to the correct position, the staff releases the pull ring 77. The spring 76 recovers its deformation under the action of elastic potential energy, pushing the T-shaped insert 75 to move in the opposite direction and re-insert it into the corresponding insertion hole 78 on the side wall of the screening channel 4, thereby firmly fixing the partition plate 6 and completing the adjustment of the guide channel width. In the actual screening process, the foamed balls, orderly conveyed to the screening channel 4 by the vibrating feeding plate 2, slide down along the guide channel formed by the first partition plate 6 and the second partition plate 8. When they encounter the first distribution pipe, since the diameter of this distribution pipe is only suitable for the smallest size foamed ball, the smallest size foamed ball will fall directly into the first distribution pipe under the action of gravity, completing the screening of the smallest size foamed ball. Foamed balls larger than the smallest size cannot pass through the inlet of the distribution pipe and continue to slide down the guide channel. When they slide to the second distribution pipe, the diameter of this distribution pipe is suitable for the next smallest size foamed ball, and the next smallest size foamed ball falls into the second distribution pipe. In this way, foamed balls of different sizes pass through the distribution pipes of corresponding diameters along the guide channel in sequence and can all fall accurately into the matching distribution pipe. However, the largest size foamed ball cannot enter all the smaller diameter distribution pipes in front and will eventually slide to the last distribution pipe at the end of the screening channel 4 and fall into it to complete the screening. The above-mentioned graded screening method can achieve efficient and accurate screening of various foaming balls of different specifications, and the entire screening process does not require manual sorting, which greatly improves screening efficiency and accuracy.

[0028] It should be noted that the auxiliary structures on screening channel 4, other than the material distribution pipe and auxiliary partition, as well as the material collection path after the material distribution pipe, are all within the scope of existing technology. Their specific structures and working logic have been disclosed in relevant technical documents. Therefore, this embodiment will not elaborate on these existing structures in detail, but will only focus on the adjustment component 7 of partition 6 and its optimization effect on screening adaptability.

[0029] Example 2: This embodiment aims to address the problem of foamed balls easily accumulating in screening channel 4, causing screening jams and reduced efficiency. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 2 and Figure 4 - Figure 6 The partition plate 8 is provided with a toggle assembly 9, which includes two support blocks 92 symmetrically fixed on the fixed plate 5. A motor 93 is fixed to the side wall of one of the support blocks 92, and a lead screw 94 is fixed to the output end of the motor 93. The lead screw 94 is rotatably connected to the two support blocks 92. A slider 95 is installed on the outer ring thread of the lead screw 94. A lever 97 is fixed on the slider 95. A buffer ball 98 is fixed to the bottom surface of the lever 97. A limit block 96 is fixed to the bottom surface of the slider 95. A groove 91 is provided on the fixed plate 5, and the limit block 96 is slidably connected to the groove 91.

[0030] In this embodiment: Based on the screening in Embodiment 1, when the foamed balls slide along the inclined surface formed by the first partition plate 6 and the second partition plate 8 in the screening channel 4, if the foamed balls accumulate in a certain area of ​​the screening channel 4, the operator can start the motor 93 of the actuating component 9 on the second partition plate 8. After the motor 93 starts, its output end drives the lead screw 94 to rotate. Since the lead screw 94 is rotatably connected to the two support blocks 92, and the outer ring thread of the lead screw 94 is fitted with a slider 95, the slider 95 will move linearly along the length direction of the lead screw 94 during the rotation of the lead screw 94. At the same time, the limiting block 96 on the bottom surface of the slider 95 slides in the groove 91 of the fixed plate 5, which can limit the movement direction of the slider 95 and prevent the slider 95 from deviating during the movement. As the slider 95 moves, the lever 97 fixed on the slider 95 also moves synchronously. During the movement, the lever 97 agitates the foamed balls accumulated in the screening channel 4, dispersing them and ensuring that the foamed balls can continue to slide smoothly along the inclined surface and enter the corresponding distribution pipe. In addition, the buffer ball 98 fixed to the bottom of the lever 97 can buffer the foamed balls when agitating them, preventing the lever 97 from directly contacting the foamed balls and causing damage.

[0031] By adjusting component 9, the foam balls accumulated in screening channel 4 can be cleared in a timely manner, effectively preventing screening jams caused by foam ball accumulation, ensuring that the screening machine always maintains high screening efficiency, and further optimizing the working performance of the screening machine.
