Abstract
Description
Technical Field
[0001] The present application relates to the technical field of slice preparation, and in particular to a slice sample preparation device for viscosity detection. Background Art
[0002] With the rapid development of the polyester industry, my country's polyester chip production has reached considerable scale. In addition to fiber-grade chips, there are also bottle-grade, film-grade, and industrial yarn chips. Intrinsic viscosity can be used to characterize the molecular weight of polymers and reflect the degree of polymerization of polyesters. This provides valuable guidance for predicting process control during production and product operability. Therefore, efficient and accurate viscosity testing methods are crucial. The current viscosity testing process primarily involves sample pretreatment → sample and solvent measurement → sample dissolution → relative viscosity measurement → calculation of intrinsic viscosity. Sample pretreatment typically involves cutting the chips into small pieces (four pieces per pellet for low-viscosity chips and eight pieces per pellet for high-viscosity chips) and then weighing them. Manual cutting and slicing is time-consuming and laborious, and poses safety risks and can easily injure hands. Furthermore, the uniformity of the cut chips varies depending on the operator, leading to poor reproducibility between experiments, reducing efficiency and increasing testing costs.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0032] like Figures 1 to 7 As shown, the present application provides a slicing sample preparation device for viscosity testing, comprising a housing 1, a conical block 11 being provided at the lower end of the interior of the housing 1, and a discharge port 12 being provided at the bottom of the housing 1, through which the chopped slice particles can be easily moved downward to the discharge port 12;
[0033] A shearing assembly 2 for shredding the slices is provided inside the shell 1, a second driving member 6 for adjusting the position of the shearing assembly 2 is provided on one side of the shell 1, a first opening and closing assembly 3 for dividing the internal space of the shell 1 is provided inside the shell 1, a screening assembly 4 for filtering the shredded slices is provided inside the shell 1, and a second opening and closing assembly 7 for controlling the opening and closing of the discharge port 12 is provided at the bottom of the shell 1.
[0034] In this embodiment, when in use, the slices are first poured into the shell 1, and then the slices are cut by the shearing component 2, and then the first opening and closing component 3 is started to allow the shredded slices located above the first opening and closing component 3 to fall downward, and the shredded particles are screened by the screening component 4, and the discharge port 12 is randomly opened by the second opening and closing component 7, so that the particles can be discharged through the discharge port 12.
[0035] like Figure 3 As shown, the shearing assembly 2 includes a cover body 21, and a first motor 22 is installed on the top of the cover body 21. The output shaft end of the first motor 22 rotates and extends to the bottom of the cover body 21 and is provided with a shearing head 23. The shearing head 23 is a component made of stainless steel. The shearing head 23 made of stainless steel can avoid rust caused by long-term use, thereby further improving its service life.
[0036] In this embodiment, after the slices are poured into the housing 1 , the first motor 22 is controlled to drive the shearing head 23 to rotate, and the slices are sheared by the rotation of the shearing head 23 .
[0037] like Figure 4As shown, the first opening and closing component 3 includes a fixed block 31 fixed inside the shell 1, the fixed block 31 is semicircular, the top of the fixed block 31 is rotatably connected to a movable block 32, the movable block 32 is semicircular, and a second motor 33 is installed at the bottom of the fixed block 31, and the output shaft end of the second motor 33 is connected to the movable block 32.
[0038] In this embodiment, after the slices are sheared by the shear head 23 in the shearing assembly 2, the movable block 32 is driven to rotate by the second motor 33, so that the movable block 32 rotates to overlap with the fixed block 31, so that the port on one side of the fixed block 31 is opened, so that the slices can fall onto the screening assembly 4.
[0039] like Figure 2 、 Figure 5 and Figure 6 As shown, the screening assembly 4 includes a fixing ring 41 fixedly arranged inside the housing 1, a screen 42 is provided at the lower end of the fixing ring 41, and the screen 42 is slidably connected to the inside of the housing 1, and an elastic member 43 is provided between the fixing ring 41 and the screen 42, and the elastic member 43 is preferably a spring;
[0040] A first driving member 5 for driving the screen 42 to vibrate is provided inside the shell 1. The first driving member 5 includes a third motor 51 fixedly mounted on one side of the shell 1. The output shaft end of the third motor 51 rotates and extends to the inside of the shell 1 and is provided with a cam 52. The cam 52 conflicts with the bottom surface of the screen 42.
[0041] In this embodiment, the cam 52 is driven to rotate by the third motor 51, and the cam 52 rotates and contacts the screen 42, so that the screen 42 can move up and down inside the shell 1, so that the elastic member 43 can be deformed, causing the screen 42 to vibrate, so that the sliced particles that have been sheared at the top of the screen 42 can better pass through the screening of the screen 42 and fall.
[0042] like Figure 6 As shown, a slide groove 13 is symmetrically provided inside the housing 1 , and a slider 421 is symmetrically provided on the outside of the screen 42 , and the slider 421 is slidably connected to the inside of the slide groove 13 .
[0043] In this embodiment, when the screen 42 moves up and down inside the shell 1, the screen 42 drives the slider 421 to move up and down along the inside of the slide groove 13. The sliding connection between the slide groove 13 and the slider 421 can prevent the screen 42 from rotating. The restriction of the slider 421 and the slide groove 13 can prevent the screen 42 from moving too far and causing damage to the elastic part 43, thereby further ensuring its service life.
[0044] like Figure 3As shown, the second driving member 6 includes a fixing frame 61 fixed to one side of the shell 1, a guide block 64 is fixed on the top of the fixing frame 61, and a guide groove 65 is opened inside the guide block 64. A cylinder 62 is also provided on the fixing frame 61, and the telescopic end of the cylinder 62 is connected to a connecting plate 63. The connecting plate 63 slides through the guide groove 65 and is fixedly connected to the top of the cover body 21. The connection between the connecting plate 63 and the guide groove 65 can prevent the connecting plate 63 from being offset when moving.
[0045] In this embodiment, when it is necessary to pour the slices into the shell 1, the cylinder 62 drives the connecting plate 63 to move upward, so that the connecting plate 63 drives the cover 21 to move upward, and the cover 21 drives the shearing head 23 to move upward, so that the shearing head 23 moves to the top outside of the shell 1, and the slices can be poured into the shell 1 at random. Then, the cylinder 62 drives the connecting plate 63 to move downward, so that the cover 21 covers the top of the shell 1, and the first motor 22 in the shearing assembly 2 can be started to make the shearing head 23 slice and shred. There is no need for the staff to lift the cover 21, which saves more labor.
[0046] like Figure 7 As shown, the second opening and closing assembly 7 includes a fixed plate 71 fixed to the bottom of the shell 1, and two groups of fixed plates 71 are symmetrically provided. The two groups of fixed plates 71 are located on both sides of the discharge port 12. A baffle 72 is slidably connected between the two groups of fixed plates 71, and a handle 721 is provided on one side of the baffle 72.
[0047] In this embodiment, after the sliced particles are screened by the screening assembly 4, the baffle 72 is moved outward by pulling the handle 721, so that the lower end of the discharge port 12 is opened, allowing the sliced particles inside the shell 1 to be discharged.
[0048] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
