Description

Technical Field

[0001] The utility model belongs to the technical field of testing the strength characteristics of solid materials by mechanical stress, and relates to a device for testing the binding limit value when tiles are packaged, in particular to a tile destructive tensile testing machine. Background Art

[0002] Before leaving the factory, tiles are usually bundled with strapping tape. Before packaging, the strength of the strapping tape needs to be determined based on the ultimate tensile force (i.e., breaking force) that the tiles can withstand when packaging, so as to avoid the tiles from scattering due to too loose binding, or the tiles from being squeezed and broken due to too tight binding.

[0003] At present, the ultimate tensile force that tiles can withstand when packing is generally obtained from the tile compressive strength test data to determine the binding strength of the packing tape.

[0004] The tile compressive strength test is carried out with the help of a tile pressure tester. In the prior art, a tile pressure tester is usually driven by a hydraulic loading system to apply force to the surface of the tile on the test platform to gradually apply pressure to perform a compressive strength test. For example, the tile pressure tester disclosed in the authorization announcement number CN205352831U controls the pressing part through the hydraulic loading system on the fixed frame to gradually apply pressure to the tile on the support seat to perform a compressive strength test to obtain the strength characteristics of the tested tile.

[0005] Since the tested tiles are placed flat on the test platform and the pressure end of the force-applying component is flat, this does not conform to the actual packaging situation of the tiles (when packaging, multiple tiles are stacked vertically and the strapping tape is tightened from the top to bundle the tiles). It is not scientific to obtain the ultimate tensile force that the tiles can withstand when packaging from the tile compressive strength test data, and this data cannot determine the reasonable strapping strength. Utility Model Content

[0006] In order to solve the above deficiencies in the prior art, the utility model aims to provide a tile destructive tensile tester to achieve the purpose of accurately obtaining the ultimate tensile force that tiles can withstand when packing.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a tile destructive tensile tester, comprising a testing tile support frame, a movable measuring assembly mounted on the tile support frame, and a strapping tape for binding the tested tiles; the movable measuring assembly comprises a sliding block slidably mounted on the tile support frame, a fixed block fixedly mounted on the tile support frame, a tensile gauge fixedly mounted on the sliding block, and a tightening member mounted on the fixed block and connected to the sliding block;

[0008] One end of the strapping tape is connected to the tensile gauge, and the other end is connected to the fixed block; the tightening member can pull the sliding block and the tensile gauge to move toward the fixed block to tighten the strapping tape.

[0009] As a limitation of the present invention, the movable measuring assembly is mounted on the top of the tile support frame.

[0010] As a further limitation of the present invention, a plurality of sets of fixing holes are provided on the top of the tile support frame;

[0011] The fixing block is installed in one of the groups of fixing holes by means of bolts to achieve fixed installation on the tile support frame.

[0012] As another limitation of the present invention, the tightening member includes a trapezoidal nut mounted on a fixed block, a trapezoidal lead screw assembled on the trapezoidal nut, and a hand wheel fixed to an operating end of the trapezoidal lead screw;

[0013] The connecting end of the trapezoidal lead screw is rotatably connected to the sliding block.

[0014] As a further limitation of the present invention, both ends of the strapping belt are connected by mechanical transverse and longitudinal tooth opening and closing buckles to form connecting buckles to achieve connection with the tensile gauge and the fixed block.

[0015] As a third limitation of the present utility model, a tile pre-fixing assembly is provided on one side of the tile support frame;

[0016] The tile pre-fixing assembly comprises at least one hand wheel screw rod assembled on the side column of the tile support frame, and the hand wheel screw rod is perpendicular to the measured tile on the tile support frame to press the measured tile.

[0017] As a further limitation of the present invention, a non-slip rubber pad is fixedly provided on the top pressing end of the hand wheel screw.

[0018] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0019] (1) The framework of the utility model is simple, portable, and easy to operate. It can be arranged at the production site to sample tiles at different time points for experiments to determine the optimal tension value for packaging. In addition, the utility model uses the strapping belt as a force-applying component and the tightening member as a driving component to control the tightening of the strapping belt to achieve force application on the tested tile, completely simulating the actual force conditions of the tiles during packaging, and can accurately measure the ultimate tension that the tiles can withstand during packaging.

[0020] (2) When the tiles are actually packed, the packing belt is tightened from the top. The utility model sets the movable measuring component on the top of the tile support frame to make the force measurement point more scientific. In addition, the top of the tile support frame is provided with multiple sets of fixing holes, and the fixing block can be installed on any set of fixing holes by bolts, and cooperates with the sliding assembly structure of the sliding block on the tile support frame, so that the installation position of the movable measuring component can be changed according to needs, and multi-point measurement at the front, middle and back can be realized.

[0021] (3) The strapping belt of the utility model is fixed by a mechanical horizontal and vertical tooth opening and closing buckle, which is convenient for disassembly and installation and has a more solid structure.

[0022] (4) In the utility model, a tile pre-fixing assembly is provided on one side of the tile support frame, which is used to support the tested tile placed in the tile support frame to prevent it from tipping over. In addition, an anti-slip rubber pad is provided at the end of the tile pre-fixing assembly to prevent damage to the tested tile. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

[0031] The present embodiment is a tile destructive tensile testing machine, comprising a tile support frame 1, a movable measuring component 2 and a strapping tape 3. The tile support frame 1 provides a placement space for the tested tile 5 during testing, the strapping tape 3 binds the tested tile 5, and the movable measuring component 2 controls the tightening of the strapping tape 3 and measures the tension value, thereby being able to scientifically and accurately test the ultimate tension that the tiles can withstand when being packaged.

[0032] 1. Tile support frame 1

[0033] The tile support frame 1 can provide a placement space for the tested tile 5, such as Figure 1 As shown, it includes two side-by-side rectangular frames 101, and a plurality of reinforcing beams 102 are connected between the rectangular frames 101 to form a stable structure as a whole. A tile pre-fixing assembly is provided on one side of the tile support frame 1, and the tile pre-fixing assembly includes at least one handwheel screw 103 threadedly assembled on the side column of the tile support frame 1. The handwheel screw 103 is perpendicular to the measured tile 5 on the tile support frame 1, and rotating the handwheel screw 103 can make the end of the handwheel screw 103 approach or move away from the measured tile 5. In this embodiment, there are two handwheel screws 103, and an anti-slip rubber pad 104 is fixed at the end (i.e., the top pressure end) of the handwheel screw 103 to avoid damaging the tile surface.

[0034] like Figure 3 As shown, by rotating the hand wheel screw 103 so that its pressing end is close to the measured tile 5, the measured tile 5 can be pressed toward the other side of the tile support frame 1 to prevent the measured tile 5 from tipping over.

[0035] 2. Movable measuring components 2

[0036] The movable measuring assembly 2 is mounted on the top of the tile support frame 1. Figure 2 As shown, it includes a sliding block 201, a fixing block 202, a tension gauge 203 and a tightening member.

[0037] It should be noted that there is a certain gap between the two rectangular frames 101 constituting the tile support frame 1, so a slide-like structure is formed at the top. In addition, a plurality of groups of fixing holes 105 are provided on the tile support frame 1, and each group of fixing holes 105 includes two holes, which are respectively provided at the tops of the two rectangular frames 101. In this embodiment, a total of four groups of fixing holes 105 are provided on the tile support frame 1.

[0038] like Figure 1As shown, the sliding block 201 is slidably assembled on the top of the tile support frame 1; the fixed block 202 is installed in one group of fixing holes 105 of the tile support frame 1 by bolts and nuts to achieve fixed installation on the top of the tile support frame 1; the dynamometer 203 is an existing structure, one end of which is fixedly installed on the sliding block 201; the tightening piece is assembled on the fixed block 202 and connected to the sliding block 201, and can control the sliding block 201 to move closer to or away from the fixed block 202.

[0039] By installing the fixing block 202 in different fixing holes 105 and adaptively adjusting the position of the sliding block 201, the installation position of the movable measuring component 2 on the top of the tile support frame 1 can be changed, thereby changing the force measuring point.

[0040] Furthermore, the tightening member includes a trapezoidal nut, a trapezoidal lead screw 204 and a hand wheel 205. Figure 2 As shown, the trapezoidal nut is mounted on the fixed block 202; the trapezoidal lead screw 204 is assembled on the trapezoidal nut, and the connecting end of the trapezoidal lead screw 204 is rotatably connected to the sliding block 201; the hand wheel 205 is fixed to the operating end of the trapezoidal lead screw 204. By rotating the trapezoidal lead screw 204 through the hand wheel 205, the sliding block 201 can be pulled toward the fixed block 202.

[0041] 3. Packing tape 3

[0042] The strapping tape 3 is used to bind the tested tile 5 on the tile support frame 1 and is a force-applying component in this embodiment. Figure 1 As shown, both ends of the strapping belt 3 are connected by a mechanical transverse and longitudinal tooth opening and closing buckle 4 to form a connecting buckle, wherein the connecting buckle at one end is connected to the tension gauge 203, and the connecting buckle at the other end is connected to the fixing block 202. In this embodiment, the strapping belt 3 and the mechanical transverse and longitudinal tooth opening and closing buckle 4 both adopt the existing structure.

[0043] When the trapezoidal lead screw 204 is rotated by the hand wheel 205 to pull the sliding block 201 toward the fixed block 202, the dynamometer 203 and the strapping belt 3 connected to the dynamometer 203 will move toward the fixed block 202 synchronously, thereby achieving the tightening of the strapping belt 3.

[0044] When using this embodiment, if Figure 3As shown, first install the movable measuring assembly 2 on a suitable position of the tile support frame 1; then neatly place the tiles 5 to be tested on the tile support frame 1, and rotate the handwheel screw 103 so that its top pressure end approaches the tiles 5 to be tested until the tiles 5 to be tested are pre-fixed; then connect one end of the packing belt 3 to the fixed block 202, and the other end passes under the tiles 5 to be tested and connects to the dynamometer; finally, rotate the trapezoidal lead screw 204 through the handwheel 205, tighten the packing belt 3, observe the tiles 5 to be tested, and read the value of the dynamometer 203 when the tiles 5 to be tested show signs of damage such as cracks. The obtained value is the ultimate tensile force that the batch of tiles can withstand when packing.

[0045] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
