DETAILED DESCRIPTION

[0043] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0044] like Figures 1 to 3 As shown, a test device for a steel bar bundling machine according to a preferred embodiment of the present invention includes a frame 1, a control device 2, a limit device 3 and a steel bar mesh device, wherein the control device 2 is located above the frame 1, the limit device 3 is located below the frame 1, and the steel bar mesh device is located inside the frame 1.

[0045] The steel mesh device includes a retractable component 4 and a cleaning component 5 that cross each other. The number of the retractable component 4, the cleaning component 5 and the limiting device 3 is at least one group. In this embodiment, the retractable component 4 and the limiting device 3 are four groups, and the cleaning component 5 is one group. Of course, according to actual needs, the number of the retractable component 4, the cleaning component 5 and the limiting device 3 can be increased accordingly.

[0046] A fixing plate 6 is provided inside the frame 1, and the fixing plate 6 can be arranged horizontally or vertically. In this embodiment, a horizontal arrangement is preferred, and the telescopic component 4 and the cleaning component 5 are located on the fixing plate 6. In order to form a simulated steel mesh, the telescopic component 4 and the cleaning component 5 cross each other, and a vertical cross arrangement is preferably adopted.

[0047] like Figures 4 to 7 As shown, the telescopic component 4 includes a telescopic shaft unit 41, the telescopic shaft unit 41 includes multiple telescopic shafts 411, each group of cleaning components 5 includes multiple optical axes 51, and the telescopic shafts 411 and the optical axes 51 are cross-arranged up and down to form a simulated steel mesh.

[0048] Specifically, the telescopic assembly 4 further includes a telescopic block 42 and a guide rod 43 . The telescopic block 42 and the guide rod 43 are both disposed on the fixed plate 6 . The telescopic shaft 411 moves forward and backward along the guide rod 43 under the drive of the telescopic block 42 .

[0049] The telescopic shaft unit 41 includes a bracket 412 and a slider 413. The bracket 412 is located above the slider 413, the bracket 412 is connected to the telescopic block 42, and the slider 413 is slidably connected to the guide rod 43. The telescopic shaft 411 can move forward and backward along the guide rod 43 driven by the telescopic block 42.

[0050] In addition, the bracket 412 is provided with a mounting hole 7 that matches the telescopic shaft 411, and the mounting hole 7 is used to match the telescopic shaft 411. The telescopic shaft 411 is a stepped shaft or a tapered shaft with a variable diameter, which is used to match the optical axis 51 to obtain simulated steel meshes with different cross-sectional sizes. At the same time, the telescopic shaft 411 adopts a variable diameter shaft, and when there is a binding wire node at the intersection node of the telescopic shaft 411 and the optical axis 51, it is conducive to the telescopic shaft 411 to be loosened from the optical axis 51.

[0051] like Figure 8 and Fig. 9 As shown, the cleaning assembly 5 is connected to the fixing plate 6 through the fixing seat 8, and the fixing seat 8 is located in the middle of the array of telescopic components 4. The optical axis 51 is installed on the fixing seat 8, and the optical axis 51 can be replaced with different diameters to form a simulated steel mesh with different cross-sectional sizes with the telescopic shaft 411.

[0052] The cleaning assembly 5 includes a connecting rod 52, and the two ends of the connecting rod 52 are provided with a left scraper 9 and a right scraper 10, and the left scraper 9 and the right scraper 10 are provided with through holes. Through the through hole and the optical axis 51, the scraper can slide left and right along the optical axis 51. Because the left scraper 9 and the right scraper 10 are respectively installed at the two ends of the connecting rod 52, the connecting rod 52 can slide axially relative to the fixed seat 8. The connecting rod 52 drives the left scraper 9 and the right scraper 10 to slide left and right relative to the fixed seat 8. When the left scraper 9 is close to the left end of the fixed seat 8, the right scraper 10 is located away from the right end of the fixed seat 8; similarly, when the right scraper 10 is close to the right end of the fixed seat 8, the left scraper 9 is located away from the left end of the fixed seat 8. With this design, when one of the scrapers cleans the wire section on the optical axis 51 at one end, the scraper at the other end is reset to the original state before cleaning the wire section. Therefore, you can directly enter the next test without waiting. The two ends of the test device are used in turn for the knotting test of the steel bar binding machine, which can save the energy consumption of the equipment. The cleaning component 5 also includes a left and right moving mechanism 53, which can drive the left scraper 9 and the right scraper 10 to move.

[0053] When the telescopic shaft 411 and the optical axis 51 of the simulated steel mesh on the left are tied with wire knots and begin to loosen automatically, the telescopic block 42 will drive the telescopic shaft 411 unit to move backward. In order to prevent the wire knot from being tied too tightly and the telescopic component 4 from loosening, causing the optical axis 51 to deform and become unable to detach, a limiting device 3 is required to fix the optical axis 51.

[0054] like Figures 10 to 13As shown, a limit plate 11 is provided inside the frame 1, and the limit device 3 is located on the limit plate 11 and is arranged in four groups. Specifically, the limit device 3 includes a limit telescopic member 31 and a limit block 32 arranged up and down, and the limit block 32 is U-shaped. The limit block 32 with a U-shaped structure matches the optical axis 51. When the limit telescopic member 31 is extended, the optical axis 51 is in the U-shaped structure of the limit block 32, and the deformation of the optical axis 51 is limited in the moving direction of the telescopic component 4. At the same time, the limit block 32 is provided with a space-avoiding structure of the connecting rod 52.

[0055] When the limiting telescopic member 31 drives the limiting block 32 to separate from the optical axis 51 , the limiting device 3 withdraws from the movement area of ​​the left scraper 9 and the right scraper 10 of the cleaning component 5 , and does not affect the cleaning of the wire section by the cleaning component 5 .

[0056] In addition, a limit stop block 12 is also provided on the frame 1, which serves as a support for the limit block 32 of the limit device 3 in the direction in which the telescopic component 4 loosens the wire section, thereby preventing the telescopic component 4 from being loosened too much and causing damage to the limit device 3, thereby ensuring the rigidity of the limit device 3.

[0057] The steel bar tying machine ties the cross position of the steel bars by placing the tying area of ​​the steel bar tying machine at the cross position of the steel bars, and installing the iron wire of the wire coil in the steel bar tying machine. The iron wire is sent out through the wire feeding mechanism of the steel bar tying machine, guided by the guide mechanism of the steel bar tying machine, and the iron wire is looped around the cross position of the steel bars through the forming mechanism of the steel bar tying machine. The wire twisting mechanism of the steel bar tying machine holds and twists the wire loop until the cross position of the steel bars is tightly tied by the iron wire, and at the same time, the cutting mechanism of the steel bar tying machine cuts off the end of the iron wire.

[0058] In the production of rebar tying machines, it is necessary to conduct detailed tests on the various functions of the above-mentioned rebar tying machines, one of which is the tying test of the rebar tying machine. In the past, the tying test was conducted on a cross-arranged steel mesh. The tester needed to use a rebar tying machine to tie the nodes where the steel bars crossed on the steel mesh. The tester would judge whether the rebar tying machine was qualified by judging the tying effect, the state of the wire knots and other factors. After each rebar tying machine test was completed, the wire knots on the steel mesh needed to be cleaned. Due to the large number of knotting tests of the rebar tying machine, cleaning the wire knots on the steel mesh requires a lot of manpower and time, resulting in a decrease in test efficiency. In the long run, this will limit the mass production of rebar tying machines.

[0059] When the rebar bundling machine test equipment of the present invention is used to test it, the tester only needs to stay on the spot to use the rebar bundling machine to bind the nodes on the simulated rebar mesh. After the rebar bundling machine test is completed, the equipment can automatically loosen and clean the wire nodes on the simulated rebar mesh nodes, thereby achieving the purpose of continuous testing.

[0060] like Fig.14 As shown, in the initial state of the test equipment, two adjacent groups of the four groups of telescopic components 4 are in the extended state, and the other two groups are in the retracted state. At this time, the left scraper 9 is close to the left side of the fixed seat 8, and the limit device 3 is in the extended state, limiting the optical axis 51. The telescopic shafts 411 on the two groups of telescopic components 4 in the extended state and the optical axis 51 of the cleaning component 5 together form a simulated steel mesh, which can be used for testing the steel bar bundling machine, and wire knots are tied at the nodes of the simulated steel mesh.

[0061] like Fig.15 As shown, after the test of the steel bar bundling machine is completed, under the control of the control device 2, the limiting device 3 limits the optical axis 51, and the telescopic shaft 411 is forced to loosen from the optical axis 51, so that the two sets of telescopic components 4 in the extended state are recovered. At this time, the wire section will be left on the optical axis 51.

[0062] like Fig.16 As shown, after the retractable shaft 411 is recovered, the limiting retractable member 31 of the limiting device 3 drives the limiting block 32 to be recovered and exit the motion range of the left scraper 9 and the right scraper 10 .

[0063] like Fig.17 As shown, the left scraper 9 and the right scraper 10 move to the left driven by the left-right moving mechanism 53, the left scraper 9 moves to the leftmost side, the right scraper 10 is on the right side of the fixed seat 8, and the wire section hanging on the optical axis 51 is cleaned by the left scraper 9.

[0064] like Fig.18 As shown, after the cleaning of the left wire section is completed, the two sets of telescopic components 4 are kept in the retracted state, and the other two sets of telescopic components 4 that were originally in the retracted state are extended to form a simulated steel mesh with the right side of the optical axis 51. The limit device 3 is extended to limit the optical axis 51, and the simulated steel mesh on the right side can be used for the test of the steel bar binding machine.

[0065] Similarly, when the steel bar binding machine has finished testing the simulated steel bar mesh on the right side, the wire section of the simulated steel bar mesh on the right side can be loosened by the control device 2. At the same time, the wire section hanging on the optical axis 51 is cleaned by the right scraper 10 to complete the cleaning action. The left side of the test equipment can be used for testing the steel bar binding machine again. In this way, the cleaning of the wire section can be completed in a short time and the next test can be started, so as to achieve a highly efficient binding test.

[0066] The testing equipment of the steel bar bundling machine described in the present invention is used in the binding test link of the steel bar bundling machine, and a simulated steel mesh is used for binding the wire sections of the steel bar bundling machine, and the wire sections can be automatically loosened and cleaned. By changing or combining the cross-sectional dimensions of different simulated steel meshes, the binding test of the steel bar bundling machine under various cross-sections can be realized, and it can also be used for the test of different models of steel bar bundling machines. Compared with the existing testing method of the steel bar bundling machine, the steel mesh composed of steel bars of different specifications is used for the test, which occupies a large testing site, requires frequent movement of the test personnel, and requires manual cleaning of the wire sections, etc., the present invention can realize the standardization and automation of the test, reduce the investment of test personnel and time, and better meet the needs of mass production of steel bar bundling machines.

[0067] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
