Technical Field

[0002] The vulcanizer is an instrument that continuously measures the changes in various properties of the rubber during the vulcanization process. Its working principle is to measure the changes in the shear modulus of the rubber during the vulcanization process. The shear modulus is proportional to the crosslinking density. Therefore, the measurement results reflect the changes in the crosslinking degree of the rubber during the vulcanization process. It can measure important parameters such as the initial viscosity of the rubber, scorch time, vulcanization speed, positive vulcanization time and oversulfurization reversion. As one of the important instruments for testing the performance of polymer materials, the preparation of test samples by the vulcanizer has also attracted much attention.

[0003] After high-resolution material sampling, irregular-shaped pressed sheets or films are usually formed. When conducting further tests, cutting and sampling operations are required, and some samples need to be standardized before testing. Especially for vulcanizer sampling, the polymer film needs to be made into a rectangular film with an area of ​​2.5cm*2.5cm. The existing operation is basically to use scissors to cut the irregular-shaped pressed sheets or films into regular square pieces, and then use tools such as rulers to fix the corners, and then cut them into test samples of standard size. This requires a lot of effort to use a ruler to compare the right-angled edges, and it takes a lot of manpower and energy to test large quantities of samples.

[0027] Embodiment 1

[0028] like Figure 1-3 As shown, a vulcanization test sample cutting and calibration equipment comprises an operating table 1, on which a cutting area and a calibration area are provided, wherein the calibration area is detachably fixed to the right side of the cutting area; the calibration area comprises a first right-angled side 21 and a second right-angled side 22 which are perpendicular to each other, and a standard sample table 23 is fixedly attached to the intersection of the first right-angled side 21 and the second right-angled side 22; the second right-angled side 22 comprises a fixed side 221 welded to the first right-angled side 21, and a slidable side 222, wherein the slidable side 222 slides horizontally along the fixed side 221 through a gear set 24; a guillotine 25 is provided at the end of the slidable side 222 away from the first right-angled side 21; and scale marks are provided on the upper surfaces of the first right-angled side 21 and the second right-angled side 22.

[0029] During use, the operator can cut the pressed sheet or film processed by the open mill and other equipment in the cutting area. After cutting, the sample with right-angled edges is clamped against the first right-angled edge 21 and the second right-angled edge 22, and the slidable edge 222 on the second right-angled edge 22 is slid. Under the action of the gear set 24, the guillotine 25 at the end continuously slides horizontally along the fixed edge 221 and approaches the boundary of the standard sample table 23 of the specified size, and is positioned using the scale mark set on the upper surface of the second right-angled edge 22, and then the guillotine 25 is cut along the boundary of the standard sample table 23 to obtain the third right-angled edge that meets the requirements. Slide the slidable edge 222, the guillotine 25 is away from the sample, and the pressed sheet or film is rotated to cut the fourth right-angled edge in the same way. Finally, the cut vulcanization test sample is compared and calibrated with the standard sample table 23. If there are any extra corners, they can be further micro-polished until they are flush with the standard sample table 23 to obtain the vulcanization test standard sample, and then further testing can be performed.

[0030] Furthermore, the gear set 24 includes at least two gears. In this embodiment, the gear set 24 uses two gears to facilitate the horizontal movement of the slidable edge 222 along the fixed edge 221, thereby driving the guillotine 25 to move closer or farther away.

[0031] Embodiment 2

[0032] Different from the above-mentioned embodiment 1, the calibration area is detachably fixed on the right side of the cutting area, and the detachability includes one of hinge fixing, bolt fixing, and latch fixing. In this embodiment, the cutting area is fixed on the left side of the calibration area by a hinge. In this way, when a large number of standard test samples are prepared, an assembly line operation step of "cutting-sample preparation-calibration" can be formed. Further, the cutting area includes a symmetrically arranged fixed column 31, on which a cutter 33 is assembled through a spring 32, and a cutting table 34 is also arranged below the cutter 33. A turntable 35 is installed below the cutting table 34, so that the cutting table 34 can move in a circle. The power of the cutter 33 can be added to both sides of the upper shaft assembled with the spring 32, so that the balance is better and the force is evenly applied. The springs 32 are pressed at both ends of the moving knife shaft to eliminate the gap between assembly and processing, thereby ensuring the stability of the cutting equipment. When cutting irregularly shaped pressed sheets or films, manual pressure can also be directly used as power, which is simple and efficient to operate.

[0033] Furthermore, a symmetrical slider track 4 is provided on the operating table 1 and in the cutting area, and the fixed column 31 can slide in the symmetrical slider track 4. The design of the slider track 4 can control the distance between the cutter 33 and the cutting table 34. After the irregular sample on the cutting table 34 is fixed, the fixed column 31 is directly moved. After reaching the target position, the position of the fixed column 31 is limited by bolts, and then cutting is performed; after the cutting is completed, the bolts are loosened, the fixed column 31 is moved, the cutter 33 is moved away, and the turntable 35 under the cutting table 34 is rotated, the uncut boundary is rotated to be parallel to the cutter 33, and then the fixed column 31 is moved closer, bolted, and the knife is cut to complete the preliminary cutting of the irregular sample.

[0034] Embodiment 3

[0035] Different from the above-mentioned second embodiment, the operating table 1 is further provided with a number of storage boxes 5, and the storage boxes 5 are arranged between the cutting area and the calibration area. After the initial cutting of the irregular sample is completed, the sample can be placed in the storage box 5 for standby, so as to prepare and calibrate the standard sample. Furthermore, three storage boxes 5 are provided, and the storage boxes 5 can also be used as storage boxes, which are convenient for placing and storing tools such as rulers, grinding sheets, and utility knives.
