Description

Technical Field

[0001] The utility model relates to a TPU masterbatch, in particular to a novel device for detecting color difference of the TPU masterbatch. Background Art

[0002] Masterbatch is a new type of polymer material, also known as pigment preparation. It is mainly used in plastics. It is composed of three elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading an extraordinary amount of pigment into the resin. It can be called pigment concentrate, so its tinting power is higher than the pigment itself.

[0003] At present, there are two main methods for TPU masterbatch detection. One is the cuvette detection method, but the cuvette detection method has a problem. The color difference measured by this method is not very accurate, because the masterbatch is a particle, and there are still gaps between the particles when placed in the cuvette, and the gaps will affect the color difference measured by the instrument. The other is the injection molded plate or thin sheet detection method. The injection molded plate or thin sheet detection method has two problems. The first problem is that the laboratory needs to have a two-roll mill / small injection molding machine / medium-sized cast film machine equipment, which requires a large equipment investment. The operators need to be trained professionals, and there is a certain safety risk of burns and pressure injuries. The second problem is that when a two-roller machine / injection molding machine / cast film machine is needed for sheeting, the two-roller machine is calendering molding, and the injection molding machine is injection molding, which is different from the cast TPU film process, and the masterbatch performance on the machine is different; the medium-sized cast film machine requires 10kg-20kg of raw materials for casting, and requires more than 2 operators to start the machine at the same time, resulting in a large waste of manpower and material resources.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In response to the problems in the related art, the present invention proposes a novel TPU masterbatch color difference detection device to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] A novel device for detecting color difference of TPU masterbatch comprises a frame, a vertical plate fixedly connected to the frame, a pretreatment component provided on the vertical plate, the pretreatment component comprising a top groove opened on the top of the vertical plate, an electric telescopic rod symmetrically provided on the bottom end of the top groove, the output end of the electric telescopic rod fixedly connected to an L-shaped slider, the L-shaped slider being slidably connected to the top groove, a stirring motor fixedly mounted on the top end of the L-shaped slider, a stirring shaft rod provided on the output end of the stirring motor, the stirring shaft rod passing through the L-shaped slider and fixedly connected to a stirring blade, a vacuum oven body and a heating oven body being sequentially mounted on one side of the outer surface of the vertical plate, a workbench fixedly mounted on one end of the frame close to the vertical plate, a beaker body and a culture dish body being sequentially provided on the workbench, and a clamping assembly being provided on the end of the workbench close to the vertical plate.

[0008] Furthermore, in order to stabilize the beaker body on the workbench, the clamping assembly includes a clamping box fixedly connected to the top end of the frame, a clamping cavity is opened inside the clamping box, a bidirectional threaded rod is rotatably connected in the clamping cavity, a moving block is symmetrically provided on the bidirectional threaded rod, the moving block is threadedly connected to the bidirectional threaded rod, the top end of the moving block passes through the workbench and is fixedly connected to the arc-shaped clamping block.

[0009] Furthermore, in order to make the L-shaped slider slide stably in the top groove, sliding grooves are opened on both ends of the inner surface of the top groove, and sliding blocks are fixedly connected to both ends of the outer surface of the L-shaped slider, and the sliding blocks are slidably connected to the sliding grooves.

[0010] Furthermore, in order to facilitate the rotation of the bidirectional threaded rod, one end of the bidirectional threaded rod extends outside the clamping box and is connected to the output end of the reciprocating motor, and the reciprocating motor is fixedly installed outside the clamping box.

[0011] Furthermore, in order to facilitate personnel control, a controller is fixedly installed on one side of the outer surface of the frame, and the controller is electrically connected to the reciprocating motor, the stirring motor and the electric telescopic rod.

[0012] Furthermore, in order to prevent the arc-shaped clamping block from damaging the beaker body, a rubber gasket is fixedly connected to the inner surface of the arc-shaped clamping block.

[0013] Furthermore, in order to stabilize the frame on the ground, support legs are fixedly connected around the bottom end of the frame.

[0014] The beneficial effects of the utility model are:

[0015] 1. Place the masterbatch and TPU particles into a beaker containing dimethylacetamide (DMAc) solution. Fix the beaker on the workbench with the help of the clamping assembly. The electric telescopic rod extends and retracts to allow the L-shaped slider to slide in the top groove. The sliding of the L-shaped slider places the stirring blade inside the beaker. The stirring motor starts working, driving the stirring blade to rotate inside the beaker to fully mix the masterbatch, TPU particles, and dimethylacetamide (DMAc) solution. Place the mixed solution into a vacuum oven to remove bubbles in the solution to improve film quality. Pour the degassed solution into a petri dish of appropriate size. After the liquid is completely cast, place it into the heating oven to obtain a masterbatch film sheet. Use a thickness gauge to test the thickness of the film sheet. Use a colorimeter to test the position of the same thickness.

[0016] 2. By placing the beaker body between the arc-shaped clamping blocks, the reciprocating motor works, and the reciprocating motor drives the bidirectional threaded rod to rotate, so that the moving block slides toward each other on the bidirectional threaded rod, and the arc-shaped clamping block slides accordingly. The sliding of the arc-shaped clamping block clamps the beaker body, which can prevent the beaker body from shaking during the stirring process, further provide a more uniform mixing effect, and at the same time, reduce the risk of solution overflow due to shaking, which can effectively improve the safety of operation.

[0030] Working principle;

[0031] In actual application, first, weigh 2g-4g of masterbatch (standard sample and sample) and 3g-6g of TPU particles (select the polyester polyether model with corresponding hardness according to the masterbatch carrier) and put them into the beaker body 11 filled with dimethylacetamide (DMAc) solution, and place the beaker body 11 between the arc clamping blocks 9.
