Description

Technical Field

[0001] This utility model relates to the field of antibacterial amino molding compound technology, and in particular to a raw material testing device for the production of antibacterial amino molding compounds. Background Technology

[0002] Amino plastics are thermosetting resins formed by the reaction of amino or amide compounds with formaldehyde. Amino resins are non-toxic, odorless, hard, scratch-resistant, colorless, and translucent, and can be made into various brightly colored plastic products. They are widely used in aerospace, electrical appliances, and other fields. In addition, their foam plastics can be used as sound insulation and heat insulation materials. Antibacterial amino molding compounds are thermosetting plastics that have antibacterial and bactericidal functions by adding antibacterial agents to amino molding compounds. They are widely used in tableware, electrical parts, sanitary ware, and other fields.

[0003] In the production process of antibacterial amino molding compounds, the testing of the uniformity of mixing between raw materials and antibacterial agents is a core aspect of quality control. Current conventional testing methods rely on two main approaches: firstly, manual visual inspection (judging the mixing effect by observing color differences and agglomerated particles in the reaction vessel), which can only assess the surface state of the materials and cannot penetrate to detect the internal mixing uniformity. Furthermore, these methods are easily affected by ambient light and subjective human judgment errors. Secondly, sampling testing methods are used (which require interrupting the mixing process and opening the reaction vessel to take a sample for microscopic observation to assess particle distribution). This offline testing method not only leads to production interruptions but also poses a significant risk of error due to the limited sampling location (usually only fixed points are taken). The inconsistency between local test data and overall mixing quality may lead to quality incidents such as "testing qualified but uneven mixing in the output material."

[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issues related to antibacterial amino molding compounds, this invention provides a raw material testing device for the production of antibacterial amino molding compounds.

[0006] The raw material testing device for the production of antibacterial amino molding compounds provided by this utility model adopts the following technical solution:

[0007] A raw material testing device for the production of antibacterial amino molding compounds includes a reaction vessel and a feed inlet on the upper side of the reaction vessel. The reaction vessel is equipped with uniformly distributed stirring components inside and uniformly distributed detection and sampling components on the outer side of the reaction vessel. The detection and sampling components include a sampling cylinder embedded in the reaction vessel, an adjusting cylinder rotatably connected inside the sampling cylinder, and a rotating component fixedly installed at one end of the adjusting cylinder located on the outer side of the reaction vessel.

[0008] Furthermore, the detection and sampling assembly also includes an adjustment block located at one end of the sampling cylinder outside the reaction vessel, a sampling groove slidably installed inside the adjustment block, the adjustment block being fixedly installed outside the reaction vessel, and the end of the sampling groove away from the adjustment block being located inside the adjustment cylinder.

[0009] Furthermore, the sampling cylinder includes uniformly distributed sampling holes on its outer side, and uniformly distributed slots are provided around the circumference of one end of the sampling cylinder located on the outer side of the reactor.

[0011] Furthermore, the outer side of the adjusting cylinder is provided with evenly distributed output holes, and the rotating component is symmetrically provided with buckling components on the side near the sampling cylinder. The buckling components are connected to the buckling slots, and the output holes correspond to the sampling holes.

[0014] (2) The raw material testing device for antibacterial amino molding compound production described in this utility model uses the cooperative design of rotating parts and snap-fit ​​parts to quickly align the detection hole and the output hole, ensuring that the sampling position is fixed and highly repeatable, reducing human operation errors, improving data comparability, and opening and closing the sampling slot by rotating the adjustment cylinder. The sampling process does not require opening the reaction vessel, which reduces the risk of external contamination and avoids oxidation or volatilization problems caused by material exposure. Moreover, the snap-fit ​​design of rotating parts and snap-fit ​​slots allows for interval sampling at different time points in the mixing process, such as the initial mixing stage and the intermediate stabilization stage, to form time series data, which is of great value for evaluating the timeliness of mixing process parameters.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0022] This utility model provides a raw material testing device for the production of antibacterial amino molding compounds, including a reaction vessel 1 and a feed inlet 2 opened on the upper side of the reaction vessel 1. The reaction vessel 1 is provided with uniformly distributed stirring components 4, and the reaction vessel 1 is provided with uniformly distributed detection and sampling components 3 on the outer side. The detection and sampling components 3 include a sampling cylinder 31 embedded in the reaction vessel 1, an adjusting cylinder 33 rotatably connected inside the sampling cylinder 31, and a rotating component 34 fixedly installed at one end of the adjusting cylinder 33 located on the outer side of the reaction vessel 1.

[0023] Specifically, reactor 1 is used to mix and process antibacterial amino molding compound raw materials, feed inlet 2 is used to add amino molding compound raw materials and antibacterial agents, detection and sampling component 3 is used to take samples of the mixed materials in reactor 1 and perform subsequent detection, and stirring component 4 is used to stir the amino molding compound raw materials and antibacterial agents to make them mix better.

[0024] In this embodiment, the sampling and detection component 3 also includes an adjustment block 32 located at one end of the sampling cylinder 31 outside the reactor 1, a sampling groove 35 slidably installed inside the adjustment block 32, the adjustment block 32 being fixedly installed outside the reactor 1, and the end of the sampling groove 35 away from the adjustment block 32 being located inside the adjustment cylinder 33.

[0025] Specifically, the sampling cylinder 31 can convey materials, the adjusting block 32 is used to fix the sampling cylinder 31 and install the rotating part 34, the adjusting cylinder 33 can continue to convey the materials conveyed by the sampling cylinder 31, the rotating part 34 is used to adjust the position of the adjusting cylinder 33, and the sampling groove 35 is used to receive the materials conveyed by the adjusting cylinder 33 through the sampling cylinder 31.

[0026] In this embodiment, the sampling cylinder 31 includes sampling holes 311 evenly distributed on the outer side, and the sampling cylinder 31 has evenly distributed slots 312 on the circumference of one end of the sampling cylinder 31 located on the outer side of the reaction vessel 1.

[0027] Specifically, the sampling hole 311 allows the material in the reactor 1 to flow into the sampling component 3 when sampling and testing are required. The slot 312 can fix the adjusting cylinder 33 and lock it into the slot 312 for fixation during adjustment.

[0028] In this embodiment, the adjusting block 32 is symmetrically provided with protrusions 321 inside, and the sampling groove 35 is symmetrically provided with sliding grooves 351 on the bottom side. The sampling groove 35 is slidably connected to the protrusions 321. The protrusions 321 allow the sampling groove 35 to be slidably installed inside the adjusting cylinder 33 and play a fixing role for the sampling groove 35 when the adjusting cylinder 33 rotates. The sliding grooves 351 are used for the sampling groove 35 to slide through the protrusions 321, which facilitates installation and removal.

[0029] In this embodiment, the regulating cylinder 33 has evenly distributed output holes 331 on its outer side, and the rotating component 34 has symmetrically arranged latching components 341 on the side near the sampling cylinder 31. The latching components 341 are latched and connected to the latching groove 312. The output holes 331 and the sampling holes 311 are positioned corresponding to each other.

[0030] Working principle: In the initial state, the output hole 331 on the outside of the regulating cylinder 33 and the sampling hole 311 on the outside of the sampling cylinder 31 are separated, and the fastener 341 is located inside the slot 312. The operator adds the raw materials and antibacterial agent required for processing antibacterial amino molding compound into the reactor 1 through the feed port 2 for mixing. First, the motor is started to drive the stirring component 4 to rotate, and then the stirring component 4 mixes and stirs the materials inside the reactor 1. After processing for a period of time, the operator can use the detection sampling component 3 to sample and test the mixed materials inside the reactor 1 to detect whether the antibacterial agent inside is mixed evenly.

[0031] Furthermore, the rotating component 34 is first rotated by a handle located on its outer side, which in turn drives the regulating cylinder 33 to rotate inside the sampling cylinder 31. When it reaches the designated position, the locking element 341 inside the rotating component 34 engages with the slot 312 on one side of the sampling cylinder 31 for fixation. At the same time, the output hole 331 rotates to a position concentric with the sampling hole 311 on the outer side of the sampling cylinder 31. Then, the material inside the reactor 1 flows into the sampling trough 35 through the engagement of the sampling hole 311 and the output hole 331. After sampling is completed, the rotating component 34 is rotated by turning the handle, causing the locking element 341 to engage with the slot 312, and simultaneously driving the regulating cylinder... Rotating the 33 component moves the output hole 331 away from the sampling hole 311, and the adjusting cylinder 33 is fixed by the buckle 341 and the slot 312. Then, the operator can pull out the sampling slot 35 by the handle. The sampling slot 35 slides on the protrusion 321 inside the adjusting block 32 through the sliding groove 351 at the bottom of the sampling slot 35, so the sampling slot 35 can be easily removed and the internal material can be tested. Moreover, the engaging design of the rotating component 34 and the slot 312 allows for interval sampling at different time points in the mixing process, such as the initial mixing stage and the intermediate stabilization stage, to form time series data, further improving the detection accuracy of the mixing degree of antibacterial amino molding compound raw materials.

[0032] Furthermore, by setting multiple sets of the detection and sampling components 3 and setting several sampling holes 311 and output holes 331, materials at different locations inside the reactor 1 can be sampled and detected, avoiding the local deviation problem of traditional single-point detection and more comprehensively reflecting the uniformity of antibacterial agent dispersion.
