Description
Technical Field
[0001] This utility model belongs to the field of bracket production and testing technology, specifically a testing machine for the production of a dryer protective bracket. Background Technology
[0002] A clothes dryer is a household appliance that uses electric heating to instantly evaporate the moisture from washed clothes. It is especially useful in northern winters and the humid, rainy seasons in the south where clothes are difficult to dry. Furthermore, clothes dryers are widely used in industrial production to dry fabrics and improve production efficiency. The protective bracket for the clothes dryer is usually placed inside the dryer to hold the clothes waiting to be dried, making efficient use of the internal space and increasing the capacity for drying clothes at one time. During the production of the protective bracket, its performance needs to be tested to identify and remove defective products; therefore, a testing machine for the production of clothes dryer protective brackets is required.
[0003] Existing testing machines for dryer protective bracket production have certain drawbacks. Typically, operators need to move the protective brackets to the testing mechanism for testing. However, this increases the workload for operators and reduces the testing efficiency when testing large quantities of protective brackets. Therefore, protective brackets are usually transported using a conveyor structure. However, testing protective brackets on the conveyor structure can cause misalignment, leading to inaccurate test results. Furthermore, placing protective brackets on the conveyor structure can easily damage it, reducing its lifespan. Frequent disassembly and maintenance of the conveyor structure by operators further increases their workload and fails to meet user needs. Utility Model Content

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0028] Example 1

[0030] In this utility model, the conveying structure 2 includes a conveying seat 6 symmetrically installed on the test chamber 1 and a conveyor belt structure 7 set on the conveying seat 6. The conveying structure 2 is made of high temperature resistant material. Several sets of positioning structures 5 are equally spaced and vertically installed on the conveyor belt structure 7 and are inserted and positioned by the support feet of the protective bracket. Both ends of the conveying structure 2 are set on the outside of the test chamber 1. The positioning structure 5 has a cylindrical structure and a positioning groove that matches the support foot. The positioning groove is open. The test chamber 1 is provided with a support structure 9 to stably support the conveying structure 2. The upper end surface of the conveyor belt structure 7 is flush with the upper end surface of the conveying seat 6.
[0031] In this utility model, the support structure 9 includes a first support member 10 which is respectively disposed on the inner wall of the test chamber 1 and connected to one side of the lower end face of the conveyor seat 6, and a second support member 11 which is vertically installed on the inner bottom surface of the test chamber 1 and connected to the other side of the lower end face of the conveyor seat 6. The second support member 11 includes a support bar 12 which is respectively connected to the test chamber 1 and the conveyor seat 6, and several sets of support rods 13 which are vertically installed between the two sets of support bars 12. Support blocks 14 connected to the lower end face of the conveyor seat 6 can be detachably installed on both sides of the outer surface of the test chamber 1. The vertical cross-section of the first support member 10 and the support block 14 is "L" shaped.
[0032] In this utility model, the lifting structure 3 includes a first drive structure 15 detachably installed on the lower end face of the test chamber 1, a screw transmission device 16 disposed inside the test chamber 1 and detachably connected to the output shaft of the first drive structure 15, and a lifting component 17 detachably connected to the screw transmission device 16 and controlling the lifting and lowering of the protective bracket. Several sets of lifting structures 3 are disposed between two sets of conveying structures 2 and lift the middle part of the lower end face of the protective bracket, so that the protective bracket is separated from the conveyor belt structure 7, and the support feet of the protective bracket are also connected to the positioning structure 5, which facilitates the test structure 4 to perform performance testing on the protective bracket.
[0033] In this utility model, the lifting component 17 includes a lifting plate 18 that is attached to the lower end face of the protective bracket and two sets of lifting rods 19 that are symmetrically and vertically installed on the lower end face of the lifting plate 18. The screw drive device 16 is arranged between the two sets of lifting rods 19 and is provided with a mounting block connected to the lifting rods 19.
[0034] In this utility model, the test structure 4 includes a second drive structure 20 that can be detachably installed on the upper surface of the test housing 1 and a test piece 21 that is disposed inside the test housing 1 and connected to the second drive structure 20. A pressure sensor device 22 is provided on the upper surface of the test piece 21, and a connecting rod 23 that is coaxially connected to the output shaft of the second drive structure 20 is vertically installed in the middle of the upper surface of the pressure sensor device 22.
[0035] In this invention, the test structure 4 also includes several sets of heating structures symmetrically installed inside the test chamber 1. The heating structures are used to adjust the ambient temperature inside the test chamber 1 so that the protective bracket is at the ambient temperature when the dryer is working, thereby improving the accuracy of the test results.
[0036] In summary, the protective bracket to be tested is inserted into the positioning structure 5 via the support feet and positioned and connected to the conveyor belt structure 7. The heating structure is activated to adjust the ambient temperature inside the test chamber 1. The protective bracket is then transported to the area to be tested via the conveyor belt structure 7. The lifting structure 3 is activated, and the lifting rod 19 is moved upward by the first drive structure 15 and the lead screw transmission device 16. This causes the lifting rod 19 to move the lifting plate 18 upward, which lifts the protective bracket and separates it from the conveyor belt structure 7. The second drive structure 20 is activated, which moves the connecting rod 23 downward. This causes the connecting rod 23 to move the test piece 21 downward via the pressure sensor device 22, allowing the test piece 21 to perform a strength test on the protective bracket.
[0037] Example 2
[0038] Reference Figure 2 and Figure 6 - Figure 5This is the second embodiment of the present invention, wherein the test chamber 1 is provided with a sealing component for sealing the test mechanism, and the sealing component reduces the temperature loss inside the test chamber 1.
[0039] In this utility model, the sealing component includes a sealing strip 8 disposed inside the conveyor seat 6 and attached to the inner wall of the conveyor belt structure 7. Both ends of the test chamber 1 are provided with a first through groove that matches the conveyor structure 2. The sealing strip 8 can seal the first through groove to reduce gas leakage from the inside of the conveyor belt structure 7.
[0040] The sealing assembly of this utility model also includes a sealing structure 24 respectively disposed on the outer surface of the test chamber 1 and the inner side of the test chamber 1, and a limiting structure on the test chamber 1 that limits the sealing structure 24. Both ends of the test chamber 1 are provided with second through grooves for the protection bracket to enter and exit. Both sets of sealing structures 24 are disposed in the forward direction of the conveyor belt structure 7 and provide movable sealing for the second through grooves.
[0041] In this utility model, the sealing structure 24 includes a rotating seat 25 detachably mounted on the upper side of the second through groove and a sealing plate 26 rotatably mounted on the inner side of the rotating seat 25. An elastic sealing gasket 27 is provided on the side of the sealing plate 26 near the second through groove. The lower end face of the sealing plate 26 is rounded and fits against the upper end face of the conveyor belt structure 7, thereby sealing the second through groove.
[0042] The limiting structure of this utility model includes a first limiting strip 28 that can be detachably installed on the outer surface of the test chamber 1 and several sets of second limiting strips 29 that can be detachably installed on the sealing plate 26 and magnetically attracted to the first limiting strip 28. The first limiting strip 28 and the second limiting strip 29 are respectively set as magnetic strips that attract each other. A gap is provided between the first limiting strip 28 and the second limiting strip 29 to prevent the first limiting strip 28 and the second limiting strip 29 from contacting and colliding with each other.
[0043] In summary, when the conveyor belt structure 7 moves the protective bracket via the positioning structure 5, and the protective bracket contacts the sealing structure 24, the elastic sealing gasket 27 causes the sealing plate 26 to flip on the rotating seat 25, allowing the conveyor belt structure 7 to transport the protective bracket into the interior of the test chamber 1. When the protective bracket separates from the sealing structure 24, the sealing plate 26 resets under gravity, causing the elastic sealing gasket 27 to contact the test chamber 1 for buffering. The first limiting strip 28 and the second limiting strip 29 magnetically attract each other, causing the sealing plate 26 to move to one side of the test chamber 1, thereby limiting the sealing plate 26. This allows the sealing plate 26 and the elastic sealing gasket 27 to work together to improve the performance of the test chamber 1.
[0044] Example 3
[0045] Reference Figure 1 - Figure 7 This embodiment is obtained by combining Embodiment 1 and Embodiment 2.
[0046] The positioning structure 5 and the conveying structure 2 work together to position the protective bracket. The first drive structure 15, the screw drive device 16 and the lifting component 17 work together to separate the protective bracket from the conveyor belt structure 7. The second drive structure 20, the connecting rod 23, the pressure sensor device 22 and the test piece 21 work together to perform an overall strength test on the protective bracket, thereby selecting out unqualified protective brackets. The support structure 9 and the support block 14 work together to improve the overall stability of the conveying structure 2.
[0047] The sealing strip 8 and the sealing strip 8 can improve the sealing performance of the test chamber 1. The rotating seat 25, the sealing plate 26 and the elastic sealing gasket 27 work together to facilitate the loading and unloading of the protective bracket by the conveying structure 2. The first limit strip 28 magnetically attracts the second limit strip 29, which can improve the connection stability between the sealing plate 26 and the test chamber 1, thereby reducing the temperature loss inside the test chamber 1.
[0048] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it.
