Description

Technical Field

[0001] This utility model relates to the field of plastic additive masterbatch sampling technology, and in particular to a sampling device for plastic additive masterbatch production. Background Technology

[0002] In the production and quality control of plastic additive masterbatches, representative samples must be obtained from sealed packaging bags for effective component analysis and performance testing of raw materials or finished products. This step is crucial for ensuring product quality stability and batch consistency. Therefore, a specialized sampling device is needed to achieve rapid, safe, and hygienic sampling operations, and to promptly identify the source of samples to avoid batch confusion, thereby meeting the stringent requirements of process standardization and data traceability in modern production.

[0003] In existing technologies, the commonly used sampling method involves using a simple tool, typically consisting of a handheld rod with a trough-shaped container with a sharp tip fixed to one end. The operator holds the tool directly, aligns the tip of the trough with the plastic packaging bag, and inserts it, causing some masterbatch material to fall into the trough. The tool is then withdrawn to complete the sampling.

[0004] However, the aforementioned traditional technical solutions have revealed several inherent defects in practical applications. First, because the handheld lever and the conical grooved tube are an inseparable integrated structure, the entire tool must be replaced if a single component is damaged, increasing usage costs. Simultaneously, the fixed structure limits the flexibility of changing sampling heads to different specifications for different sampling scenarios, reducing the equipment's applicability. Second, the entire sampling process is not a continuous closed loop; the sampling operation and sample marking are independent. After sampling, operators must separately find and grasp a marker to mark the packaging bag. This process not only increases the number of steps and time but also easily contaminates the marking tool, affecting marking efficiency and clarity, especially if hands are already contaminated with material. Furthermore, the most prominent safety hazard lies in the fact that after use, the sharp conical grooved tube remains exposed without effective protection. Whether during storage, carrying, or cleaning, it is highly likely to cause accidental cuts to operators or those nearby. The sharp tip itself can also deform or be damaged by collisions or drops, affecting the effectiveness and safety of subsequent use. These shortcomings collectively limit the overall effectiveness and safety of traditional sampling tools in actual production environments. Utility Model Content

[0005] The purpose of this utility model is to provide a sampling device for the production of plastic additive masterbatch, which solves three major technical problems of traditional integrated sampling tools: first, the fixed connection between the hand handle and the sampling head makes it impossible to replace or repair parts according to usage needs; second, the separation of sampling operation and sample marking process requires additional searching and use of marking tools, thereby reducing work efficiency; and third, the sharp sampling head is exposed after use, posing a safety hazard of scratching personnel and self-injury.

[0006] To achieve the above objectives, this utility model provides a sampling device for the production of plastic additive masterbatch, including a hand gripping rod. A support block is fixedly installed at one end of the hand gripping rod. A first external threaded clamp is fixedly installed on the hand gripping rod and outside the support block. A first internal conical nut is threadedly installed on the outside of the first external threaded clamp. A connecting ring is detachably inserted between the first external threaded clamp and the support block. A semi-circular extension tube is fixedly provided below one end of the connecting ring. A conical tube is fixedly provided at the extended end of the semi-circular extension tube, and the tip of the conical tube is rounded.

[0007] The handle is fixedly fitted with an anti-slip sleeve on the outside, and a second external threaded clamp is fixedly fitted at the end of the handle opposite to the first external threaded clamp.

[0008] The second external threaded clamp is concentrically connected to the hand grip to form a slot, and the slot extends into the interior of the support block.

[0009] The second external threaded clamp is threadedly fitted with a second internal conical nut on its outer side, and a pad is movably provided in the slot. The outer diameter of the pad is the same as the inner diameter of the semi-circular extension tube.

[0010] A marker pen is inserted into the slot, with the writing end of the marker pen facing the slot and the other end of the marker pen facing the inside of the slot and abutting against the pad.

[0011] The connecting ring, the semi-circular extension tube, and the tapered tube are all made of stainless steel. When the tapered tube is inserted into the slot, the semi-circular extension tube is housed inside the second external threaded clamp and holds the pad.

[0012] This utility model discloses a sampling device for the production of plastic additive masterbatch. A supporting circular block at the front end of the handle and a first externally threaded clamp form a connection interface. A connecting ring inserted at this interface can be fixed by tightening a first internal conical nut, thereby installing a sampling component consisting of a semi-circular extension tube and a conical tube. This design allows for convenient replacement of the sampling component, enhancing its flexibility of use.

[0013] To address the need for immediate marking after sampling, the device incorporates an integrated marking unit at the end of the handle. A slot formed inside the second external threaded clamp accommodates a marker pen. By tightening the second internal conical nut, the second external threaded clamp is pushed to hold the marker pen securely, achieving integrated sampling and marking operations and improving work efficiency.

[0014] To ensure safe storage, the device is designed with a unique storage method. The removed sampling component can be inserted upside down into the tail end slot, completely enclosing the sharp end of the conical tube. By filling the gap with a shim and tightening the second inner conical nut, the sampling component can be securely locked, effectively preventing accidental injury or damage to the sharp point, while also facilitating storage and transport.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-4 .

[0023] A sampling device for producing plastic additive masterbatch includes a handle 101. A support block 102 is fixedly mounted at one end of the handle 101, serving as the main connecting support structure. A first external threaded clamp 103 is fixedly mounted on the handle 101 and located outside the support block 102. A first internal conical nut 104 is threaded onto the outside of the first external threaded clamp 103. Tightening the first internal conical nut 104 causes its conical inner wall to compress the first external threaded clamp 103, generating radial elastic deformation. The clamping function is achieved by means of the first external threaded clamp 103 and the support block 102, and a connecting ring 105 is detachably inserted between them. The connecting ring 105 serves as the mounting base for the sampling component. A semi-circular extension tube 106 is fixedly provided below one end of the connecting ring 105. The semi-circular extension tube 106 forms a groove-shaped channel for accommodating the masterbatch during sampling. A tapered tube 107 is fixedly provided at the extended end of the semi-circular extension tube 106. The tip of the tapered tube 107 is rounded. This rounded corner design facilitates insertion into the packaging bag while reducing damage to the packaging material.

[0024] An anti-slip sleeve 108 is fixedly installed on the outer side of the grip 101. The anti-slip sleeve 108 is used to increase the friction of the hand during operation to prevent slippage. A second external threaded clamp 109 is fixedly installed on the end of the grip 101 opposite to the first external threaded clamp 103. The second external threaded clamp 109 and the grip 101 are concentrically connected to form a slot 110. The slot 110 provides internal accommodating space. A second internal conical nut 111 is installed on the outer side of the second external threaded clamp 109 by threads. Its function is similar to that of the first internal conical nut 104, which is used to clamp and fix the inserted object. A pad 112 is movably provided in the slot 110. The pad 112 serves as an intermediate medium for transmitting clamping force and can fill gaps when stored.

[0025] A marker 113 can be inserted into the slot 110. The marker 113 is used to mark the packaging after sampling. The writing end of the marker 113 faces the slot 110, and the other end of the marker 113 faces the inside of the slot 110 and abuts against the pad 112. The connecting ring 105, the semi-circular extension tube 106, and the tapered tube 107 are made of one piece of stainless steel, which ensures the structural strength and durability of the sampling components. When the tapered tube 107 is inserted into the slot 110, the semi-circular extension tube 106 is housed inside the second external threaded clamp 109 and holds the pad 112. This storage method can safely store the sharp tapered tube 107 and prevent accidental injury and damage.

[0026] Working principle: First, hold the anti-slip sleeve 108 to stably grip the hand grip 101, align the connecting ring 105 with its annular structure and insert it into the reserved gap between the first external threaded clamp 103 and the support block 102; then, rotate the first inner conical nut 104, causing it to move axially along the outer surface of the first external threaded clamp 103 under the guidance of the internal thread. During the forward movement, the conical inner wall of the first inner conical nut 104 applies radial compressive force to the first external threaded clamp 103, causing the first external threaded clamp 103 to produce a small amount of elastic deformation, thereby gradually tightening and finally firmly clamping the connecting ring 105 on the side of the support block 102, completing the rigid connection; at this time, the semi-circular extension tube 106 and the tapered tube 107 at the end, which are fixed together with the connecting ring 105, extend from the side of the hand grip 101, forming a sampling channel with an open groove.

[0027] When taking samples, the operator grips the anti-slip sleeve 108 and applies pressure to the surface of the plastic packaging bag by aligning the rounded tip of the conical tube 107 with the bag surface. The inclined structure of the conical tube 107 guides the tip to pierce the surface of the packaging bag and penetrate deep into the interior. The plastic additive masterbatch falls into the groove-shaped space formed by the semi-circular extension tube 106 under gravity or slight vibration. Maintaining the angle of the device, the entire assembly is pulled out of the packaging bag, and the masterbatch sample carried in the groove is taken out.

[0028] If the sample needs to be marked, the operator holds the marker 113 with the writing end facing outward and inserts the other end into the slot 110 formed by the second external threaded clamp 109 and the handle 101. The marker 113 is pushed into the bottom of the slot 110, and its end abuts against and pushes the pad 112, which is pre-placed in the slot, to move inward, so that the pad 112 is stored away to prevent loss when not in use. Then, the second inner conical nut 111 is rotated so that it rotates along the outer thread of the second external threaded clamp 109 and moves axially. The conical inner wall of the second inner conical nut 111 presses against the second external threaded clamp 109, causing it to undergo radial contraction elastic deformation. This contraction force is indirectly and evenly transmitted to the barrel of the marker 113 through the pad 112, thereby tightly clamping and fixing the marker 113 in the slot 110. After sampling, the operator can directly use the fixed marker 113 to write and mark on the sampling packaging bag.

[0029] After sampling and marking are completed, the device enters the disassembly and safe storage phase. The operator first loosens the first inner conical nut 104 to release the tightening force on the first external threaded clamp 103, allowing it to return to its original position and thus releasing the clamp on the connecting ring 105. The connecting ring 105, along with the semi-circular extension tube 106 and the conical tube 107, is then removed from the handle 101. Next, the second inner conical nut 111 is loosened to release the clamping force on the marker pen 113, and the marker pen 113 is removed from the slot 110. Then, the pointed end of the conical tube 107 of the connecting ring 105 assembly is reversed so that its tip faces inward and aligns with the entrance of the slot 110. The conical tube 107 is then partially inserted into the slot 110, while most of the arc of the semi-circular extension tube 106 is accommodated within the internal space of the second external threaded clamp 109. At this point, the pad 112 is placed in the semi-circular extension tube 106. Between the groove of the circular extension tube 106 and the inner wall of the second external threaded clamp 109, the second inner conical nut 111 is rotated again to tighten it on the second external threaded clamp 109. The second external threaded clamp 109 then contracts radially, squeezing the pad 112. The pad 112 undergoes a slight deformation under pressure, tightly filling the gap between the semi-circular extension tube 106 and the second external threaded clamp 109. The frictional force firmly locks the entire assembly of connecting ring 105, semi-circular extension tube 106 and conical tube 107 into the slot 110. At this time, the sharp end of the conical tube 107 is completely retracted into the depth of the slot 110, and the arc-shaped structure of the semi-circular extension tube 106 is wrapped inside the second external threaded clamp 109, effectively avoiding the risk of accidental injury caused by the exposed tip, and also protecting the conical tube 107 itself from impact damage.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
