Description

Technical Field

[0001] This utility model relates to the field of sorting mechanism technology, and more specifically, to a seamless differential speed sorting and conveying structure. Background Technology

[0002] In the production and processing of cemented carbide cutting tools, the PVD-coated tools need to be unloaded from the tooling of the PVD equipment for further processing. Currently, the industry commonly uses manual methods for unloading and material placement, mainly because the cutting tools strung on the rods are close together and cannot be evenly separated. Existing technology uses traditional blade conveyor belts for differential speed separation, but due to the arc-shaped gap between the two blade belts with different speeds, the cutting tools cannot transition smoothly and are prone to random rolling and bumping on the belt, resulting in poor quality. This problem is particularly serious for R-series and high-end ground cutting tools. In addition, the smooth belt surface allows the spacer rings to roll freely on the belt, further increasing the difficulty and instability of material handling. Utility Model Content

[0003] Therefore, a differential speed sorting and conveying structure capable of achieving smooth and seamless material transfer is needed to improve production efficiency and product quality. This invention, through an innovative mechanism design, uses small-diameter conveyor belts arranged side-by-side at intervals to form a conveying mechanism. Conveyor belts are interspersed between two conveying mechanisms operating at different speeds to fill the gaps and differences in height, achieving smooth material separation and overcoming the shortcomings of existing technologies.

[0004] This utility model addresses the problems of height difference and material rolling in existing differential speed sorting and conveying structures. To this end, the utility model adopts the following technical solution:

[0005] A seamless differential speed sorting and conveying structure includes:

[0006] At least three sets of conveying mechanisms, including a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism; wherein each set of conveying mechanisms includes multiple conveyor belts arranged in parallel, with a fixed gap between adjacent conveyor belts; the first conveying mechanism, the second conveying mechanism, and the third conveying mechanism operate at increasing speeds respectively;

[0007] The conveyor belt of the second conveyor mechanism is interlaced between the conveyor belts of the first conveyor mechanism and the third conveyor mechanism to bridge the speed difference between the first conveyor mechanism and the third conveyor mechanism.

[0008] Furthermore, the speed of the first conveying mechanism is less than the speed of the second conveying mechanism, and the speed of the second conveying mechanism is less than the speed of the third conveying mechanism.

[0009] Furthermore, the conveyor belt is a round belt.

[0010] Furthermore, a support plate is provided below the first conveying mechanism and the third conveying mechanism. The support plate has a semi-circular groove suitable for installing the conveyor belt, so as to prevent the conveyor belt from being displaced or having gap changes due to the action of materials.

[0011] Further, the first conveying mechanism includes a first driving component, the third conveying mechanism includes a third driving component, and the second conveying mechanism includes a second driving component; specifically, the second driving component includes a second driving motor, a first rotating roller, and a second rotating roller, wherein the second driving motor is adapted to simultaneously drive the first rotating roller and the second rotating roller to rotate synchronously via a belt; the first rotating roller and the second rotating roller are connected by multiple parallel small round belts;

[0012] A first synchronous roller and a second synchronous roller are provided between the first rotating roller and the second rotating roller. The first synchronous roller is connected to the first drive assembly via a conveyor belt; the second synchronous roller is connected to the third drive assembly via a conveyor belt.

[0013] Furthermore, the conveyor belt on the first conveyor mechanism is aligned with the conveyor belt on the third conveyor mechanism, and the small round belt is interlaced within the gap between the conveyor belts of the first and third conveyor mechanisms.

[0014] Furthermore, the diameter of the small circular belt is smaller than the diameter of the conveyor belt.

[0015] Furthermore, the first drive assembly includes a first rotary motor and a third rotary roller connected to the rotary shaft of the first rotary motor, and the third drive assembly includes a third rotary motor and a fourth rotary roller connected to the rotary shaft of the third rotary motor.

[0016] The beneficial effects of this utility model are:

[0017] By employing three conveyor mechanisms operating at different speeds, the material is gradually separated during transport, with the distance between each piece gradually increasing. Due to the fixed gaps in the conveyor belts, round materials do not roll on any of the conveyor structures, significantly improving transport stability. This structure is particularly effective in handling R-series and high-end ground blades, effectively preventing quality defects caused by rolling and impacts. Attached Figure Description

[0023] like Figures 1 to 4 As shown, the differential speed sorting and conveying structure includes at least three sets of conveying mechanisms, specifically a first conveying mechanism 2, a second conveying mechanism 3, and a third conveying mechanism 4. Each set of conveying mechanisms consists of multiple conveyor belts 1 arranged in parallel, with a fixed gap between adjacent conveyor belts 1. The first conveying mechanism 2, the second conveying mechanism 3, and the third conveying mechanism 4 operate at increasing speeds, i.e., the speed of the first conveying mechanism 2 is less than the speed of the second conveying mechanism 3, and the speed of the second conveying mechanism 3 is less than the speed of the third conveying mechanism 4. The conveyor belt 1 of the second conveying mechanism 3 is interposed between the gaps between adjacent conveyor belts 1 of the first conveying mechanism 2 and the third conveying mechanism 4 to bridge the speed difference between them, thereby achieving smooth separation and conveying of materials.

[0024] like Figures 1 to 3As shown, specifically, the first conveying mechanism 2 includes a first drive assembly 6, which includes a first rotating motor and a third rotating roller 11 connected to the rotating shaft of the first rotating motor. The third conveying mechanism 4 includes a third drive assembly 8, which includes a third rotating motor and a fourth rotating roller 12 connected to the rotating shaft of the third rotating motor. The second conveying mechanism 3 includes a second drive assembly 7, which includes a second drive motor, a first rotating roller 9, and a second rotating roller 10. The second drive motor simultaneously drives the first rotating roller 9 and the second rotating roller 10 to rotate synchronously via belts. The first rotating roller 9 and the second rotating roller 10 are connected by multiple parallel conveyor belts 1. Here, the conveyor belts 1 on the second conveying mechanism 3 are small round belts 15, the diameter of which is smaller than the diameter of the conveyor belts 1 on the first conveying mechanism 2 and the second conveying mechanism 3, to achieve seamless connection between conveying mechanisms of different speeds. In a preferred embodiment, all conveyor belts 1 can be round belts. The diameter and spacing of the conveyor belts 1 are configured according to the material size to ensure that the material will not get stuck due to excessive gaps during conveying.

[0025] like Figures 1 to 3 As shown, furthermore, a first synchronous roller 13 and a second synchronous roller 14 are provided between the first rotating roller 9 and the second rotating roller 10. The first synchronous roller 13 is connected to the first drive assembly 6 via a conveyor belt 1, and the second synchronous roller 14 is connected to the third drive assembly 8 via a conveyor belt 1. This design ensures that each conveying mechanism can operate stably at a preset speed, avoiding material accumulation or uneven separation caused by speed mismatch.

[0026] like Figure 4 As shown, a support plate 5 is provided below the first conveying mechanism 2 and the third conveying mechanism 4. The support plate 5 has a semi-circular groove suitable for installing the conveyor belt 1, so as to prevent the conveyor belt 1 from being displaced or having gap changes due to the action of materials. The setting of the support plate 5 not only increases the stability of the structure, but also extends the service life of the conveying mechanism.

[0027] The specific operating principle and process are as follows:

[0028] S1: Place materials that need to be separated at a differential speed, such as carbide blades, onto the first conveyor mechanism 2. Because the speed of the first conveyor mechanism 2 is relatively slow, the materials will move forward slowly.

[0029] S2: When the material moves from the first conveyor 2 to the second conveyor 3, because the speed of the second conveyor 3 is faster than that of the first conveyor 2, the material will gain a gap with the material behind it due to the acceleration effect of the second conveyor 3. The conveyor belt 1 of the second conveyor 3 is interlaced between the conveyor belts 1 of the first conveyor 2 and the third conveyor 4, and is at the same height, ensuring that the material will not roll or collide due to the height difference when transitioning from the first conveyor 2 to the third conveyor 4. The semi-circular groove on the pallet 5 fixes the position of the conveyor belt 1, ensuring the stability of the conveying process.

[0030] S3: The material continues to move to the third conveyor 4 via the second conveyor 3. Since the speed of the third conveyor 4 is faster than that of the second conveyor 3, the material will once again accelerate and further widen the gap with the material behind it; the semi-circular groove on the pallet 5 also fixes the position of the conveyor belt 1, ensuring the stability of the conveying process.

[0031] Through the coordinated action of the three conveying mechanisms at different speeds, the material is gradually separated during the conveying process, and the distance between each piece of material gradually increases. Because the conveyor belt 1 has a fixed gap in the middle, round materials will not roll on each conveying structure, significantly improving conveying stability. Especially when handling R-series and high-end ground blades, this structure effectively avoids quality defects caused by rolling and impacts.

[0032] In practical applications, this differential speed sorting and conveying structure can be used for the unloading and unloading process of carbide blades after PVD coating. The blades are unloaded from the tooling of the PVD equipment and placed on the first conveying mechanism 2. Through the acceleration of the second conveying mechanism 3 and the third conveying mechanism 4, the blades are gradually and evenly separated during the conveying process, avoiding the tediousness and inefficiency of manual operation, and significantly improving production efficiency and product quality.

[0033] To further illustrate the specific embodiments of this utility model, the following detailed description is provided in conjunction with actual application scenarios:

[0034] In the production process of carbide cutting tools, the PVD-coated tools typically need to be removed from the tooling for further processing. Traditional manual unloading and material handling methods are not only inefficient but also prone to causing the tools to roll and collide during transport, affecting product quality. This utility model's differential speed sorting and conveying structure achieves efficient automated sorting and conveying through the following steps:

[0035] First, the PVD-coated blade is removed from the tooling and placed on the first conveyor mechanism 2. The first conveyor mechanism 2 operates at a relatively slow speed, ensuring that the blade enters the conveying system smoothly in the initial stage. Due to the fixed gap between the conveyor belts 1 of the first conveyor mechanism 2, the blade does not roll during conveying, maintaining good stability.

[0036] When the blade moves from the first conveyor mechanism 2 to the second conveyor mechanism 3, the speed of the second conveyor mechanism 3 is faster than that of the first conveyor mechanism 2. The acceleration of the blade by the second conveyor mechanism 3 creates a gap between it and the blades following it. The conveyor belt 1 of the second conveyor mechanism 3 is interlaced between the conveyor belts 1 of the first conveyor mechanism 2 and the third conveyor mechanism 4, ensuring that the blade does not roll or collide due to the height difference when transitioning from the first conveyor mechanism 2 to the third conveyor mechanism 4. The semi-circular groove on the pallet 5 fixes the position of the conveyor belt 1, preventing displacement of the conveyor belt 1 due to the material, thus ensuring the stability of the conveying process.

[0037] The blade continues to move through the second conveyor mechanism 3 to the third conveyor mechanism 4. Because the third conveyor mechanism 4 moves faster than the second conveyor mechanism 3, the blade will again accelerate, further widening the gap with the blades following it. The semi-circular groove on the pallet 5 also fixes the position of the conveyor belt 1, ensuring the stability of the conveying process.

[0038] Through the coordinated action of the three conveying mechanisms at different speeds, the blades are gradually separated during the conveying process, and the distance between each blade gradually increases. Because the conveyor belt 1 has a fixed gap in the middle, the circular blades will not roll on each conveying structure, significantly improving conveying stability. Especially when processing R-series and high-end ground blades, this structure effectively avoids quality defects caused by rolling and impact, significantly improving production efficiency and product quality.

[0039] In addition, the differential speed sorting and conveying structure of this utility model also has the following advantages:

[0040] Seamless connection: By interlacing the conveyor belt 1 of the second conveyor mechanism 3 between the conveyor belts 1 of the first conveyor mechanism 2 and the third conveyor mechanism 4, a seamless connection of the three conveyor mechanisms with different speeds is achieved, ensuring a smooth transition of materials during the conveying process.

[0041] High stability: Each conveyor structure consists of multiple conveyor belts 1 arranged in parallel with a fixed gap in the middle. Therefore, round materials will not roll on each conveyor structure, which significantly improves the conveying stability.

[0042] Differential speed sorting is effective: The three conveyor mechanisms with different speeds are arranged in an alternating manner, which can achieve efficient differential speed sorting over short distances, and the sorting process is more stable and reliable.

[0043] Long-term stable operation: The semi-circular groove on the pallet 5 effectively prevents the conveyor belt 1 from shifting or changing gap due to the action of materials, thus ensuring the long-term stable operation of the conveying mechanism.

[0044] Therefore, the seamless differential speed sorting and conveying structure provided in this embodiment, through innovative mechanism design and reasonable speed control, achieves smooth separation and conveying of materials during the conveying process, significantly improving production efficiency and product quality. This structure is simple and reliable, suitable for sorting and conveying various materials, and has particularly broad application prospects in the production and processing of carbide blades.
