Description

Technical Field

[0001] This utility model belongs to the field of carbon black sampling technology, specifically relating to an automatic sampling device for carbon black granulation. Background Technology

[0002] Carbon black's high specific surface area and surface activity enable it to bind with polymer molecules, forming strong mechanical bonds that improve the mechanical strength, tensile strength, and abrasion resistance of polymer materials. In the rubber industry, carbon black's reinforcing ability is particularly significant, substantially improving the wear resistance of tire treads and the physical and mechanical properties of other rubber products.

[0003] To ensure tire wear resistance meets standards, regular sampling of carbon black is necessary to monitor its particle size distribution. Currently, carbon black sampling is mostly done manually, where a small amount of carbon black is collected manually at the sampling port of the dryer and taken back to the laboratory for testing. This manual sampling method has several problems, such as the sampling frequency being greatly affected by human factors, inaccurate sampling intervals, and difficulty in ensuring the representativeness of the samples. Furthermore, during manual sampling, workers are exposed to dust and high temperatures for extended periods, posing certain safety hazards. Utility Model Content

[0004] The present invention aims to provide an automatic sampling device for carbon black granulation. The automatic sampling is safe and fast, and the sampling results are not affected by human factors. It solves the problems of current carbon black sampling methods, which mostly rely on manual methods, resulting in sampling frequency that is greatly affected by human factors, inaccurate sampling intervals, and difficulty in ensuring the representativeness of the samples.

[0005] Therefore, the technical solution adopted by this utility model is as follows: an automatic sampling device for carbon black granulation, comprising a sampling pipe horizontally connected to the sampling hole of the carbon black pipe, a sampling hopper that moves along the sampling pipe to the carbon black pipe for sampling, a translation drive mechanism that provides translational driving force for the sampling hopper, a sampling component that receives the carbon black material in the sampling hopper, and a rotation drive mechanism that provides rotational driving force for the sampling component; the sampling hopper is generally in the shape of an inverted trapezoidal trough, the bottom of the sampling hopper is provided with a discharge hole, and a plugging cover is installed aligned with the discharge hole, the plugging cover having a vertically protruding sampling material in the center. The discharge column at the bottom of the hopper is designed to cover the discharge hole when its bottom contacts the inner wall of the sampling pipe. The bottom of the sampling pipe is provided with a receiving funnel, and the receiving funnel has a protruding post protruding from the inner wall of the sampling pipe in the center. When the sampling hopper is moved to the discharge hole and aligned with the receiving funnel by the translation drive mechanism, the protruding post lifts the discharge column and opens the blocking umbrella. The sampling assembly includes a central column, a sampling frustum, and a sampling cup arranged from bottom to top. Several sampling cups are arranged circumferentially on the sampling frustum, and the sampling cups can be rotated to align with the lower opening of the receiving funnel.

[0006] As a preferred embodiment of the above scheme, the central column is provided with a toothed groove in the circumference, and the lifting end of the rotary drive mechanism is provided with a connecting column that is horizontally inserted into the toothed groove. When the connecting column of the rotary drive mechanism moves along the toothed groove, it guides the central column to rotate, thereby driving the sampling platform to rotate. The structure is interlocked and the design is ingenious.

[0007] A further preferred embodiment is that the lowest and highest positions of the toothed groove are vertically connected, and the highest position is obliquely connected to the next lowest position, thereby forming a right-angled toothed structure. When the connecting column of the rotary drive mechanism moves from the highest position to the lowest position along the toothed groove, the sampling platform can rotate from the previous sampling cup aligned with the bottom of the receiving funnel to the next sampling cup aligned with the bottom of the receiving funnel. The structure is ingeniously designed.

[0008] A further preferred embodiment is that the discharge port of the sampling hopper is provided with a horizontal connecting plate for limiting the discharge column to pass through, and the front and rear ends of the sampling hopper are provided with sealing plates. The contact surface between the sealing plate and the inner wall of the sampling pipe is provided with a rubber sealing ring to ensure the sealing effect.

[0009] More preferably, both the translation drive mechanism and the rotation drive mechanism are driven by double-acting cylinders. The telescopic end of the translation drive mechanism is fixed to the right end of the sampling hopper. Two translation monitoring magnetic sensors are installed on the left and right sides of the translation drive mechanism at intervals. When the magnetic ring in the corresponding cylinder cavity moves to the left and is detected by the translation monitoring magnetic sensor on the left, the sampling hopper is completely located in the carbon black pipe for material collection. When the magnetic ring moves to the right and is detected by the translation monitoring magnetic sensor on the right, the discharge hole of the sampling hopper is aligned with the receiving funnel.

[0010] The translation drive mechanism automatically intakes air through the right air inlet, and the telescopic end extends to the left, thereby moving the sampling hopper to the left until it is completely inside the carbon black pipe for material collection. The translation monitoring magnetic sensor on the left side detects and records the dwell time. After the set material collection time is up, the translation drive mechanism automatically vents air through the left air inlet, and the telescopic end retracts to the right, thereby moving the sampling hopper to the right until the sampling hopper outlet aligns with the receiving funnel, thus discharging the material into the sampling cup. After the set material discharge time is up, the above steps are repeated to enter the next material collection and discharge cycle.

[0011] The rotary drive mechanism is equipped with a lifting monitoring magnetic sensor, and when the magnetic ring inside the corresponding cylinder cavity is detected by the lifting monitoring magnetic sensor, the connecting column is inserted into the lowest position of the toothed groove.

[0012] When air enters through the air inlet of the rotary drive mechanism, it drives the lifting end to move downward, thereby causing the connecting column to move along the oblique channel between the highest and next lowest positions of the toothed groove, causing the central column to rotate. Therefore, when the connecting column is just inserted into the lowest position of the toothed groove, the sampling cup is aligned with the discharge hole to take a sample. The lifting monitoring magnetic sensor detects and records the dwell time. After the set sampling time is up, the air inlet of the rotary drive mechanism automatically releases air.

[0013] More preferably, the rotary drive mechanism is mounted on the outer wall of the carbon black pipe via a drive mounting bracket. The drive mounting bracket is equipped with a limiting cover that covers the lifting end of the rotary drive mechanism. The limiting cover contains a reset spring that abuts against the top of the rotary drive mechanism. After the sampling hopper finishes discharging material, the telescopic end of the rotary drive mechanism only rises under the return force of the reset spring, causing the connecting column to return from the lowest position of the toothed groove to the highest position along the vertical channel. The structure is ingeniously designed and is more convenient and less costly than lifting and returning via a cylinder.

[0014] A further preferred embodiment is that the receiving funnel is provided with a hollow mounting plate for mounting the protruding column in the center to avoid clogging the hole. The top of the protruding column is provided with a slope, and the bottom of the discharge column is provided with a chamfer that matches the slope of the protruding column. When the discharge column comes into contact with the protruding column, the slope is provided to avoid collision. At the same time, the slope can also guide the discharge column to move to the upper right. The structure is reasonably designed.

[0015] A further preferred embodiment is that the plugging umbrella cover is provided with an anti-sway spring around the discharge column inside, ensuring that the plugging umbrella cover will not sway from side to side during the ejection process, which is a reasonable structural design.

[0016] More preferably, four sampling cups are used, and four right-angled toothed structures are provided for the toothed grooves. Each time the sampling cup moves from the highest position to the lowest position of the toothed groove, it is a process of transferring from the previous sampling cup to the next sampling cup. The number of sampling cups corresponds to the number of toothed grooves.

[0017] The beneficial effects of this utility model are:

[0018] (1) Compared with the current method of manual sampling of carbon black, this application adopts an automatic sampling device for carbon black granulation. The sampling frequency and sampling interval can be set by the start control of the translation drive mechanism and the rotation drive mechanism to realize timed and quantitative sampling, fully guarantee the representativeness of the sampling and the authority of the sampling results.

[0019] (2) The sampling hopper discharge hole is equipped with a plugging umbrella cover. The umbrella-shaped structure avoids material accumulation. The plugging umbrella cover has a vertical discharge column that extends through the horizontal bottom of the sampling hopper. When the bottom of the discharge column contacts the inner wall of the sampling pipe, the plugging umbrella cover falls on the inner wall of the sampling hopper and covers the discharge hole. However, the discharge column can be lifted by the protruding column in the middle of the receiving funnel that protrudes from the inner wall of the sampling pipe, thereby opening the plugging umbrella cover. The plugging umbrella cover can also be lifted to achieve positioning and discharge. The structural design is interlocking, novel and ingenious.

[0020] In summary, this utility model has advantages such as automatic sampling, timed and quantitative sampling, positioning and discharging, and an interlocking structural design. Attached Figure Description

[0021] Figure 1 This is a schematic diagram of the structure of this utility model.

[0022] Figure 2 for Figure 1 A magnified view of part A. Detailed Implementation

[0023] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0024] Combination Figure 1 — Figure 2 As shown, an automatic sampling device for carbon black granulation consists of a sampling pipe 2 that is horizontally connected to the sampling hole of the carbon black pipe 1, a sampling hopper 3 that moves along the sampling pipe 2 to the carbon black pipe 1 for sampling, a translation drive mechanism 4 that provides translation drive force to the sampling hopper 3, a sampling component 5 that receives the carbon black material in the sampling hopper 3, and a rotation drive mechanism 6 that provides rotation drive force to the sampling component 5.

[0025] The sampling hopper 3 has an overall inverted trapezoidal trough structure. The sampling hopper 3 has a discharge hole at its horizontal bottom, and a plugging cover 31 is installed in alignment with the discharge hole. An anti-sway spring 312 is provided inside the plugging cover 31 around the discharge column 311. The discharge column 311 is vertically inserted through the horizontal bottom of the sampling hopper 3 at the center of the plugging cover 31.

[0026] When the bottom of the discharge column 311 contacts the inner wall of the sampling pipe 2, the plugging umbrella cover 31 falls onto the inner wall of the sampling hopper 3, thereby covering the discharge hole.

[0027] The bottom of the sampling pipe 2 is provided with a receiving funnel 21. The receiving funnel 21 has a protruding post 211 protruding from the inner wall of the sampling pipe 2 in the center.

[0028] The receiving funnel 21 has a hollow mounting plate for mounting the protruding column 211 in the center. The top of the protruding column 211 has a slope 211a, and the bottom of the discharge column 311 has a chamfer with the same slope as the protruding column 211.

[0029] When the sampling hopper 3 moves to the discharge hole and aligns with the receiving funnel 21 via the translation drive mechanism 4, the protruding column 211 pushes up the discharge column 311, thereby opening the plugging cover 31.

[0030] The sampling hopper 3 has a horizontal connecting plate 312 at its discharge port to allow the discharge column 311 to pass through and be limited. The sampling hopper 3 has sealing plates 32 at its front and rear ends, and rubber sealing rings are provided on the contact surfaces between the sealing plates 32 and the inner wall of the sampling pipe 2.

[0031] The sampling assembly 5 consists of a central column 51, a sampling frustum 52, and sampling cups 53 arranged from bottom to top. Several sampling cups 53 are circumferentially spaced on the sampling frustum 52, and each sampling cup 53 can rotate to align with the lower opening of the receiving funnel 21. The central column 51 has circumferentially toothed grooves 511, and the lifting end of the rotary drive mechanism 6 has a connecting column 61 that horizontally inserts into the toothed grooves 511.

[0032] When the connecting column 61 of the rotary drive mechanism 6 moves along the toothed groove 511, it guides the central column 51 to rotate, thereby driving the sampling stage 52 to rotate.

[0033] The lowest and highest positions of the toothed groove 511 are vertically connected, and the highest position is obliquely connected to the next lowest position, thus forming a right-angled toothed structure.

[0034] Four sampling cups 53 are used, and four right-angled toothed structures are set in the toothed grooves 511.

[0035] When the connecting column 61 of the rotary drive mechanism 6 moves from the highest position to the lowest position along the toothed groove 511, the sampling stage 52 can rotate from the previous sampling cup 53 aligned with the lower opening of the receiving funnel 21 to the next sampling cup 53 aligned with the lower opening of the receiving funnel 21.

[0036] Both the translation drive mechanism 4 and the rotation drive mechanism 6 are preferably driven by double-acting cylinders.

[0037] The telescopic end of the translation drive mechanism 4 is fixed to the right end of the sampling hopper 3. Two translation monitoring magnetic sensors 8a are installed on the left and right sides of the translation drive mechanism 4 at intervals. When the magnetic ring in the corresponding cylinder cavity moves to the left and is detected by the translation monitoring magnetic sensor 8a located on the left, the sampling hopper 3 is completely located in the carbon black pipe 1 to collect material. When the magnetic ring moves to the right and is detected by the translation monitoring magnetic sensor 8a located on the right, the discharge hole of the sampling hopper 3 is aligned with the receiving funnel 21.

[0038] The rotary drive mechanism 6 is equipped with a lifting monitoring magnetic sensor 8b. When the magnetic ring inside the corresponding cylinder cavity is detected by the lifting monitoring magnetic sensor 8b, the connecting post 61 is inserted into the lowest position of the toothed groove 511.

[0039] The rotary drive mechanism 6 is mounted on the outer wall of the carbon black pipe 1 via a drive mounting bracket 7. The drive mounting bracket 7 is equipped with a limiting cover 71 that covers the lifting end of the rotary drive mechanism 6. The limiting cover 71 contains a reset spring 9 that abuts against the top of the rotary drive mechanism 6. After the sampling hopper 3 finishes discharging material, the telescopic end of the rotary drive mechanism 6 rises only under the return force of the reset spring 9, causing the connecting column 61 to return from the lowest position of the toothed groove 511 to the highest position along the vertical channel.

[0040] The translation drive mechanism 4 automatically takes in air through the right air inlet, and the telescopic end extends to the left, thereby driving the sampling hopper 3 to move to the left until it is completely inside the carbon black pipe 1 for material collection. The translation monitoring magnetic sensor 8a located on the left side detects and records the dwell time. After the set material collection time is up, the translation drive mechanism 4 automatically vents air through the left air inlet, and the telescopic end retracts to the right, thereby driving the sampling hopper 3 to move to the right until the discharge hole of the sampling hopper 3 is aligned with the receiving funnel 21, thereby discharging the material into the sampling cup 53. After the set material discharge time is up, the above steps are repeated to enter the next material collection and discharge cycle.

[0041] When air enters through the upper air inlet of the rotary drive mechanism 6, it drives the lifting end to move downward, thereby causing the connecting column 61 to move along the oblique channel between the highest and next lowest positions of the toothed groove 511, causing the central column 51 to rotate. Therefore, when the connecting column 61 is just inserted into the lowest position of the toothed groove 511, the sampling cup 53 is aligned with the discharge hole to take a sample. The lifting monitoring magnetic sensor 8b detects and records the dwell time. After the set sampling time is up, the upper air inlet of the rotary drive mechanism 6 automatically releases air, and the telescopic end of the rotary drive mechanism 6 only rises under the return force of the return spring 9. The connecting column 61 returns from the lowest position to the highest position along the vertical channel of the toothed groove 511.
