Description

Technical Field

[0001] The utility model relates to the technical field of nylon production equipment, and particularly relates to an automatic sampling device for PA6 particles. Background Art

[0002] As a high-performance engineering plastic, nylon 6 (PA6) has been widely used in the fields of automobiles, electronic appliances, textiles, packaging, etc. due to its excellent mechanical strength, wear resistance, chemical corrosion resistance and good processing performance. Ensuring the quality stability of PA6 particle raw materials is the key to ensuring the performance of the final products. Therefore, it is necessary to accurately and reliably sample and analyze the PA6 particles produced from the reaction kettle or granulation production line.

[0003] In the prior art, the sampling link in the production process of PA6 particles still generally relies on traditional manual operation, that is, a sampling port is opened on the outer wall of the feeding pipeline or conveying pipeline, and the operator inserts the sampling equipment into the pipeline to sample the PA6 particles. However, this manual sampling method requires a manual sampling rod or a long-handled instrument to be inserted into the storage bin or material flow, which has certain safety hazards. In view of this, we propose an automatic sampling device for PA6 particles. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic sampling device for PA6 particles, which solves the problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: An automatic sampling device for PA6 particles, comprising a machine shell; A sampling mechanism and a switching mechanism are arranged on the machine shell; The sampling mechanism includes an electric push rod and a moving seat fixedly connected to the output end of the electric push rod, the switching mechanism includes a suspension frame, the suspension frame is arranged below the moving seat, and a sampling bottle is detachably connected to the suspension frame.

[0006] Preferably, the sampling mechanism further includes a bracket fixedly connected to the top end of the machine shell, the bracket has a "冂" - shaped structure, the electric push rod is fixedly connected to the top end of the bracket, and a groove corresponding to the structure of the suspension frame is opened at the bottom end of the moving seat.

[0007] Preferably, limiting grooves are opened on both sides of the bracket, the limiting grooves correspond to the structure of the suspension frame, a buffer spring is fixedly connected inside the limiting grooves, and a support block is fixedly connected to the buffer spring.

[0008] Preferably, guiding grooves are opened on both sides of the limiting grooves, the guiding grooves are inclined, and the inclination directions of the two guiding grooves are the same.

[0009] Preferably, a support frame is fixedly connected to the side of the bracket, the support frame and the guide groove are positioned corresponding to each other, and a collection rack is connected to the end of the support frame.

[0010] Preferably, a stop bar is rotatably connected inside the limiting groove, the stop bar corresponds to the guide groove, and a coil spring is fixedly connected to the side of the stop bar.

[0011] Preferably, the housing has a sampling port with a diameter larger than that of the sampling bottle, and a guide rod is fixedly connected to the top of the movable seat, the guide rod passing through the bracket.

[0012] By employing the above technical solution, this utility model provides an automatic sampling device for PA6 particles, which has at least the following beneficial effects: (1) The present invention can automatically insert the sampling bottle into the flowing PA6 particles for sampling by setting a lifting moving seat in conjunction with a hanging frame with a sampling bottle, thereby reducing the risk of manual sampling. The suspended sampling bottle can swing on the hanging frame, so that the flowing PA6 particles can be used for tilt sampling.

[0013] (2) The present invention can rotate and switch the sampling bottle by means of the rotating support frame, so that it can automatically sample different batches of PA6. Therefore, the staff does not need to perform frequent sampling operations after each batch of PA6 is produced. The sampled PA6 samples can be sent for testing only after a certain period of time, which reduces the workload of the staff and avoids the loss of samples due to the staff's omission.

Specific implementation mode

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0017] An automatic sampling device for PA6 particles, as Figures 1-5 shown, includes a machine housing 1; the machine housing 1 is arranged on the production and feeding pipeline of PA6 particles or on the conveying equipment. A sampling mechanism 2 and a switching mechanism 3 are provided on the machine housing 1; the sampling mechanism 2 can perform automatic sampling operations on the PA6 particles after production, reducing the operations of the staff during sampling, and switching after sampling is completed, facilitating the staff to take PA6 samples of different production batches, and thus facilitating subsequent inspection operations.

[0018] Specifically, the sampling mechanism 2 includes a support 21 fixedly connected to the top end of the machine housing 1. The support 21 has a "冂"-shaped structure. An electric push rod 22 is fixedly connected to the top end of the support 21. The output end of the electric push rod 22 is fixedly connected to a moving seat 23. The structure of the support 21 can support the sampling mechanism 2.

[0019] In addition, the switching mechanism 3 includes a suspension bracket 31. The suspension bracket 31 is arranged below the moving seat 23. A sampling bottle 32 is detachably connected to the suspension bracket 31. The structure of the electric push rod 22 can push the suspension bracket 31, so that the suspension bracket 31 can drive the suspended sampling bottle 32 to be placed into the machine housing 1 from the sampling port 4. At the same time, the sampling bottle 32 is connected to the suspension bracket 31 through an L-shaped rod. Therefore, the sampling bottle 32 can swing with the L-shaped rod as the hinge point. When the PA6 particles are feeding or moving and conveying, the continuously flowing PA6 particles impact the outer wall of the gradually approaching sampling bottle 32, causing the sampling bottle 32 to gradually tilt when descending, so that the mouth of the sampling bottle 32 is tilted, facilitating the PA6 particles to flow into the sampling bottle 32. When the sampling bottle 32 completes sampling and rises, due to inertia, the sampling bottle 32 swings, thus shaking the PA6 particles at the top of the sampling bottle 32 to be horizontal. A groove 24 corresponding to the structure of the suspension bracket 31 is provided at the bottom end of the moving seat 23, and the groove 24 can limit the suspension bracket 31.

[0020] Furthermore, limit grooves 25 are provided on both sides of the bracket 21. The limit grooves 25 correspond to the structure of the suspension frame 31. A buffer spring 26 is fixedly connected inside the limit groove 25. A support block 27 is fixedly connected to the buffer spring 26. The limit groove 25 can guide the suspension frame 31, so that the suspension frame 31 and the sampling bottle 32 can move up and down along the limit groove 25. At the same time, the structure of the buffer spring 26, together with the support block 27, can support the suspension frame 31 and reduce the descent speed of the suspension frame 31.

[0021] It is worth noting that guide grooves 28 are provided on both sides of the limiting groove 25. The guide grooves 28 are inclined and the two guide grooves 28 are inclined in the same direction. The guide grooves 28 can guide the suspension frame 31, guiding the suspension frame 31 into the limiting groove 25 or guiding it outward from the limiting groove 25.

[0022] Furthermore, a support frame 33 is fixedly connected to the side of the bracket 21. The support frame 33 corresponds to the guide groove 28. A collection rack 34 is connected to the end of the support frame 33. The support frame 33 can support the suspension frame 31. At the same time, the support frame 33 and the guide groove 28 have the same inclination angle. The support frame 33 can support the empty sampling bottle 32 and guide the feeding through the inclination structure to realize the automatic sampling operation of PA6. The collection rack 34 can collect and store the sampling bottle 32 after sampling.

[0023] In addition, a stop bar 35 is rotatably connected inside the limiting groove 25. The stop bar 35 corresponds to the guide groove 28. A coil spring is fixedly connected to the side of the stop bar 35. Since the guide grooves 28 are all inclined structures and have the same inclination direction, the heights of the guide grooves 28 at both ends of the limiting groove 25 are different, forming a structure where one end feeds and the other end discharges. The stop bar is set at the top of the lower guide groove 28. Due to the restriction of the top of the guide groove 28, the stop bar can only rotate downwards. Therefore, it can unidirectionally limit the suspension frame 31, so that the suspension frame 31 can only move downwards along the limiting groove 25. The coil spring can automatically reset the stop bar 35.

[0024] In addition, a sampling port 4 is provided on the housing 1. The diameter of the sampling port 4 is larger than that of the sampling bottle 32. The larger diameter of the sampling port 4 can facilitate the movement of the sampling bottle 32 into the housing 1 or when it is removed after sampling, reducing the probability of contact and collision between the sampling bottle 32 and the sampling port 4. A guide rod 29 is fixedly connected to the top of the moving base 23. The guide rod 29 passes through the bracket 21. The structure of the guide rod 29 can guide the movement of the moving base 23. At the same time, the guide rod 29 is close to the side of the moving base 23, so the guide rod 29 can block the subsequent sampling bottles 32 and the suspension frame 31.

[0025] In use, the automatic PA6 particle sampling device of this utility model operates as follows: when sampling PA6 through the sampling bottle 32, the push rod motor is activated, and the moving seat 23 pushes the suspension frame 31 to move continuously downward, compressing the buffer spring 26 accordingly. As the sampling bottle 32 descends, its bottom first contacts the flowing PA6 particles, which then impact the bottle, causing it to tilt. After tilting, the bottle opening approaches the PA6 particles, allowing the bottle to load and sample them. After sampling, the electric push rod 22 retracts to the moving seat 23, while the suspension frame 31 continues to rise under the elastic push of the buffer spring 26. Because the top of the suspension frame 31 is restricted by the moving seat 23, the rebound speed of the suspension frame 31 is the same as the speed at which the electric push rod 22 retracts to the moving seat 23. During the ascent of sampling bottle 32, due to the inertia of continuous oscillation, excess PA6 particles at the top of sampling bottle 32 are shaken and fall into the housing 1, leaving a small buffer space at the top of sampling bottle 32. When the suspension frame 31 moves to the stop bar 35, since the stop bar 35 can only rotate downwards, the suspension frame 31 slides away from the limiting groove 25 along the guide groove 28 under the guidance of the stop bar 35, and moves along the support frame 33 into the collection rack 34. At the same time, after the moving seat 23 rises, the subsequent suspension frame 31 drives the sampling bottle 32 to move into the bracket 21. Adjacent sampling bottles 32 are blocked by the bottle wall and the sampling bottles 32 that have not entered the bracket 21. At the same time, when the moving seat 23 continues to push the suspension frame 31 downwards, the guide rod 29 at the top of the moving seat 23 moves synchronously, guiding the moving seat 23 and blocking the subsequent sampling bottles 32.
