Description

Technical Field

[0001] The invention belongs to the technical field of masterbatch sampling, and in particular relates to an intelligent sampling device for masterbatch inspection. Background Art

[0002] Masterbatch, also known as color seed, is a new type of colorant specially used for polymer materials, also known as pigment preparation; masterbatch is mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly attaching an extraordinary amount of pigment to the resin, which can be called pigment concentrate. Therefore, its tinting power is higher than the pigment itself; when processing, a small amount of masterbatch is mixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration.

[0003] During the production process of masterbatch, it is easy for the finished masterbatch to fail to meet the quality standards due to substandard raw materials or impurities. Therefore, in order to ensure the quality of the finished masterbatch, it is necessary to regularly sample and test the finished masterbatch on the masterbatch production line: the existing sampling method is usually for the inspector to directly hold the sampling container and take samples in the storage barrel.

[0004] Generally, the storage barrel is large, and this sampling method cannot take samples at various positions and depths in the barrel, which easily leads to distortion of the masterbatch data being tested. Therefore, it is necessary to provide an intelligent sampling device for masterbatch testing, which can take samples at different positions in the barrel to facilitate the collection of authentic data.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-7 The present invention provides a technical solution: an intelligent sampling device for masterbatch inspection, comprising a sampling mechanism, an adjustment mechanism and a lifting mechanism. The lifting mechanism is arranged in the masterbatch barrel, the adjustment mechanism is provided with three groups, which are connected to the lifting mechanism, and the sampling mechanism is provided with three groups. Each group of sampling mechanisms is connected to each group of adjustment mechanisms. The adjustment mechanism is driven up and down by the lifting mechanism, and then the sampling mechanism is driven to move into the masterbatch barrel, which is convenient for sampling.

[0033] The lifting mechanism includes a limit position component and a threaded drive component. The threaded drive component includes an outer shell 3 and a top plate 2. A first drive (not shown in the figure) is fixed inside the outer shell 3. A threaded rod 1 is fixed on the top of the outer shell 3. The threaded rod 1 runs through the inner part of the outer shell 3 and is connected to the outer shell 3 by a bearing. The threaded rod 1 is connected to the top plate 2 by a bearing. A threaded sleeve 1 6 and a threaded sleeve 2 8 are threadedly connected on the threaded rod 1. The threaded sleeve 1 6 is arranged above the threaded sleeve 2 8. A fixed plate 7 is fixed to the outside of the threaded sleeve 6. Three sets of adjustment mechanisms are connected to the fixed plate 7. The first drive is started to control the rotation of the threaded rod 1, and the fixed plate 7 is driven to move up and down through the threaded sleeve 1 6.

[0034] It should be noted that the first drive may be a motor.

[0035] Limiting ears 26 are fixed on both sides of the top plate 2 , and limiting ears 4 are fixed on both sides of the shell 3 .

[0036] The limiting assembly includes a slide bar 9 fixed between the limiting ear 1 26 and the limiting ear 2 4. The two sets of slide bars 9 are slidably connected to the fixed plate 7. By providing two sets of slide bars 9, the upward and downward movement of the fixed plate 7 can be made more stable.

[0037] The adjustment mechanism includes a connecting assembly and an expansion assembly. The connecting assembly includes three groups of fixed seats 27 fixed on the fixed plate 7. A connecting rod 10 is connected to the bearing on each group of fixed seats 27. A connecting seat 11 is fixed to the bottom of the connecting rod 10. The connecting rod 10 is connected to the sampling mechanism.

[0038] The expansion component includes a second drive 5 fixed on the threaded sleeve 8. The output end of the second drive 5 is connected to the connecting seat 11 by a bearing. Starting the second drive 5 can drive the connecting rod 10 to swing back and forth on the fixed seat 27, thereby driving the sampling mechanism to adjust to a suitable position for easy sampling.

[0039] It should be noted that the second drive 5 may be a cylinder.

[0040] The sampling mechanism includes a rotating component, a sampling component and a drawer component. The rotating component includes a mounting seat 13. The mounting seat 13 is fixed to the end of the connecting rod 10. A third drive 15 is fixed to one side of the mounting seat 13. The internal bearing of the mounting seat 13 is connected to the connecting rod 10. A connecting seat 2 16 is fixed to the outside of the connecting rod 10. The third drive 15 is fixedly connected to the connecting rod 10. The sampling component is arranged below the connecting seat 2 16. The connecting seat 2 16 is driven to rotate by the third drive 15, thereby driving the sampling component to adjust to a suitable angle.

[0041] It should be noted that the extension component and the rotation component are used in conjunction with each other.

[0042] The sampling assembly includes a fourth drive 14 fixed to the bottom of the second connecting seat 16, and a sampling shell 17 is fixed to the output end of the fourth drive 14. The bottom of the sampling shell 17 is a conical surface. The sampling shell 17 is inserted into the masterbatch by extending the fourth drive 14.

[0043] The drawer assembly includes a sampling drawer 19 arranged in a sampling shell 17. Four groups of cavities 28 are opened inside the sampling shell 17. The sampling drawers 19 are slidably connected to the cavities 28. There are four groups of sampling drawers 19. Each group of cavities 28 matches a group of sampling drawers 19. A linear drive is provided at the connection between the sampling drawer 19 and the cavity 28. The sampling drawer 19 is controlled to move in the cavity 28 by the linear drive to facilitate sampling.

[0044] A through hole 21 is provided on one side of the sampling drawer 19, and a long groove 29 is provided on one side of the sampling drawer 19 located at the through hole 21. A fifth drive 22 is fixed to one side of the long groove 29, and a baffle 23 is fixed to the output end of the fifth drive 22. The baffle 23 is slidably connected in the long groove 29. Starting the fifth drive 22 can drive the baffle 23 to slide in the long groove 29, thereby blocking the through hole 21, or no longer blocking the through hole 21.

[0045] The bearing on the other side of the sampling drawer 19 is connected to a connecting rod 2 12 , on which a swing plate 20 is fixed. A rotation drive is provided at the connection between the sampling drawer 19 and the connecting rod 2 12 , through which the swing plate 20 can be driven to swing.

[0046] A distance sensor 24 is fixed on one side of the sampling drawer 19, and a camera 25 is fixed on the top of the cavity 28. The distance sensor 24 detects the distance between the sampling drawer 19 and the inner wall of the cavity 28, and the camera 25 detects whether masterbatch is adhered to the inner surface of the sampling drawer 19.

[0047] It should be noted that the third drive 15 may be a motor, and the fourth drive 14 and the fifth drive 22 may be cylinders.

[0048] In the first embodiment, a through hole is opened on one side of the sampling shell 17 , the through hole is opposite to the through hole 21 , and a piston is arranged inside the through hole.

[0049] When it is necessary to sample the masterbatch, the piston is used to block the through hole to prevent the masterbatch from entering during sampling.

[0050] In the second embodiment, a transmission pipe 18 is detachably connected in the through hole, one end of the transmission pipe 18 is connected to a testing device, and the transmission pipe 18 is connected to a first pump body 30 .

[0051] After the sampling is completed, the piston in the through hole is pulled out and then inserted into the transmission tube 18, so that the masterbatch is transmitted to the inspection equipment through the transmission tube 18.

[0052] It should be supplemented that the first pump body 30 may be an air pump.

[0053] Working principle:

[0054] A sampling device is pre-installed in the masterbatch storage barrel when required, and the sampling component is located above the device and does not contact the masterbatch in the storage barrel. When it is necessary to extract the masterbatch for sampling and inspection, the first drive is controlled to start, driving the threaded sleeve 1 6 and the threaded sleeve 2 8 to move downward on the threaded rod 1, thereby driving the sampling mechanism to move downward. During the downward movement of the sampling mechanism, the second drive 5 is controlled to extend, driving the sampling mechanism away from the threaded rod 1, and the three groups of sampling mechanisms are distributed at different positions of the storage barrel.

[0055] Then start the fourth drive 14 to extend and insert the sampling shell 17 into the masterbatch in the storage barrel until the masterbatch submerges the sampling shell 17. When sampling is needed, the sampling drawer 19 is controlled to move in the cavity 28 through the linear drive, so that the sampling drawer 19 enters the masterbatch. During the sampling process, the distance moved by the sampling drawer 19 into the masterbatch can further determine whether the masterbatch is condensed into agglomerates: specifically, since a distance sensor 24 is provided above the sampling drawer 19, when the sampling drawer 19 moves, if the distance moved by the sampling drawer 19 does not reach the stroke of the sampling drawer 19 within a specified time (the specified time is set by the staff based on work experience), it means that the sampling drawer 19 encounters resistance when moving, indicating that there may be agglomeration of masterbatch at the front end. At this time, the swing plate 20 is controlled to rotate around the connecting rod 12 through the rotation drive to drive the swing plate 20 to swing up and down, so that the agglomerated masterbatch can be split up for easy sampling, and the sampling drawer 19 at this position is marked.

[0056] Furthermore, since there are three groups of sampling components and each group of sampling drawers 19 is divided into four layers, the storage situation of the masterbatch in the storage barrel can be further judged based on the overall situation of the sampling drawers 19 encountering resistance in moving the masterbatch. Specifically, if there are three or more groups of sampling components, and each group of sampling components has two or more groups of sampling drawers 19 encountering resistance, it means that most of the masterbatch stored in the storage barrel has condensed into agglomerates, and the agglomerates are evenly distributed, and the surface storage quality is poor. At this time, no sampling and inspection is required, and the storage barrel is marked as a defective product and then handled by the staff. If there are two groups of sampling components, and each group of sampling components has three or more groups of sampling drawers 19 encountering resistance, it means that the masterbatch agglomerated in the storage barrel is concentratedly distributed. In this way, the storage quality of the masterbatch in the storage barrel can be judged during sampling, and the distribution situation can be checked, saving the time of subsequent staff in finding masterbatch with quality problems.

[0057] When the poor storage quality of the masterbatch in the storage barrel is not identified during the sampling process, the swing plate 20 is continued to be controlled to swing. During the swinging process of the swing plate 20, the masterbatch can be shoveled into the sampling drawer 19. This continues until the sampling drawer 19 is full of masterbatch. At this time, the rotary drive is controlled to drive the swing plate 20 to swing upward, forming a vertical state to block the outlet of the sampling drawer 19, thereby preventing the masterbatch from moving out of the sampling drawer 19 when the sampling drawer 19 enters the sampling shell 17.

[0058] It should be added that when sampling, the four groups of sampling drawers 19 sample from top to bottom in sequence. For example, after the sampling of the first layer of sampling drawers 19 is completed, the second layer of sampling drawers 19 continues to sample until the last layer of sampling drawers 19 samples. This sampling method avoids mixing of masterbatches at different levels during sampling, which affects the accuracy of subsequent test data. Moreover, since the sampling drawers 19 are arranged in layers, sampling can be performed at different levels. Since sampling and testing are performed at different positions and at different levels, the real data of the masterbatch in the storage barrel can be better reflected.

[0059] After the sampling of the sampling component is completed, the first drive is started to rotate in the opposite direction, thereby driving the sampling mechanism to move upward through the threaded rod 1 until it moves out of the surface of the masterbatch. At this time, the staff pulls out the piston and inserts the transmission tube 18 into the through hole. At the same time, the fifth drive 22 is started to contract, driving the baffle 23 to slide in the long groove 29, no longer blocking the through hole 21, and connecting the transmission tube 18 to the through hole 21, and starting the first pump body 30 outside, so as to facilitate pumping the masterbatch in the sampling drawer 19 into the inspection equipment.

[0060] After the first pump body 30 is turned on for a period of time, the camera 25 is used to capture whether there is any masterbatch remaining on the sampling drawer 19. If there is any masterbatch remaining in the sampling drawer 19, it means that small agglomerated masterbatch has entered the sampling drawer 19 and blocked the transmission tube 18 when being transmitted to the inspection equipment. At this time, the power of the first pump body 30 is increased to increase the transmission force, so as to absorb the masterbatch remaining in the sampling drawer 19 and prevent the transmission tube 18 from being blocked.

[0061] Mark the sampling drawer 19 with residual masterbatch, and combine it with the sampling drawer 19 marked during sampling. If the marks are repeated, it means that the masterbatch agglomerates at the corresponding position were not well separated during the sampling process, which means that although the agglomerates at this position can be separated, there are still small agglomerates. You can inform the staff and let them deal with it.
