DETAILED DESCRIPTION

[0014] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0015] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0016] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0017] Example 1: As shown in the attached Figure 1As shown, the manual PVC resin powder press includes a base 1, a support rod 2, a fixing frame 3, a pressing rod 6, a transmission rod 5, a handle 4, a lifting screw 7, and a fixed platform 16. The support rod 2 is installed on the upper side of the base 1, one end of the fixing frame 3 is installed on the support rod 2, and the other end of the fixing frame 3 is integrally provided with a mounting tube 15 that passes through from top to bottom. The middle part of the pressing rod 6 is located in the mounting tube 15, and a pressing piece 11 is installed at the lower end of the pressing rod 6. A sample container 12 is provided on the upper side of the base 1 corresponding to the position below the pressing piece 11. A fixing piece 9 is installed on the top of the pressing rod 6. A spring 8 is sleeved on the pressing rod 6 between the upper side of the mounting tube 15 and the lower side of the fixing piece 9. A mounting hole that passes through the inside and outside is provided in the middle of the mounting tube 15. One end of the transmission rod 5 passes through the mounting hole and is transmission-connected to the pressing rod 6. A handle 4 is installed at the other end of the transmission rod 5. A fixing platform 16 is installed on the mounting tube 15. The upper end height of the fixing platform 16 is flush with the mounting tube 15, and a lifting screw 7 is threadedly connected to the upper side of the fixing platform 16.

[0018] When in use, first rotate the lifting screw 7 as needed, adjust the height of the lifting screw 7, place the PVC resin powder in the sample container 12, and then rotate the handle 4 to press the pressing rod 6 downward. When the pressing rod 6 moves downward, the spring 8 is compressed. When the lower side of the fixing piece 9 touches the lifting screw 7, the pressing rod 6 cannot continue to move downward. By setting the height of the lifting screw 7, the downward distance of the pressing rod 6, that is, the compression length of the spring 8, is controlled, thereby controlling the size of the elastic force and thus the downward pressure. With such a tool, the weight of the PVC resin powder pressed by each person can be consistent, which can improve the accuracy of the whiteness measurement result of the PVC powder.

[0019] The above manual PVC resin powder press can be further optimized and / or improved according to actual needs:

[0020] Example 2: As shown in the attached Figure 1 As shown, a scale 10 is also included, and the scale 10 is installed on the fixing platform 16. A pointer 17 passing through the scale 10 is installed at the end of the fixing piece 9. The position of the lifting screw 7 can be preliminarily set according to the scale by the scale 10.

[0021] Example 3: As shown in the attached Figure 1 As shown, the base 1 also includes an electronic scale 13 and an electronic scale display 14. The electronic scale 13 and the electronic scale display 14 are provided on the upper side of the base 1, and the sample container 12 is placed on the electronic scale 13. By providing the electronic scale 13, the downward pressure force can be displayed, and the height of the lifting screw 7 can be adjusted more accurately according to the displayed data, thereby more accurately controlling the downward pressure force. The threaded connection method of the lifting screw 7 ensures high adjustment accuracy.

[0022] Example 4: As shown in the attached Figure 1 As shown, the fixing plate 9 is detachably mounted on the pressing rod 6 by fixing bolts. In this way, it is convenient to install and disassemble.

[0023] Example 5: As shown in the attached Figure 1 As shown, the end portion where the fixing frame 3 is connected to the support rod 2 is a clamp, which can be used to clamp the support rod 2 and adjust the height by means of bolts. This is not only convenient for installation, but also allows the height of the fixing frame 3 to be set as required.

[0024] Example 6: As shown in the attached Figure 1 As shown, the fixing frame 3 is in the shape of a square, with a hollow middle portion, so as to reduce the overall weight while ensuring strength.

[0025] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
