Description

Technical Field

[0001] The invention relates to the field of shoe production, in particular to a folding resistance testing machine for a shoe production line. Background Art

[0002] In today's highly competitive footwear market, the quality and durability of shoes are directly related to consumer satisfaction and brand reputation. Therefore, in the footwear production process, it is particularly important to ensure that the shoes have good quality and durability. As an important equipment specially used to evaluate the performance of shoe materials and structures under repeated folding and bending conditions, the folding tester plays a key role. It can simulate various folding and bending conditions that shoes may experience during actual use, and evaluate the folding resistance of shoes by accurately measuring and analyzing parameters such as deformation and stress distribution of shoes.

[0003] For example, a folding resistance testing machine proposed in the Chinese patent with patent announcement number CN208568493U realizes accurate testing of the folding resistance of shoes through a specific mechanical structure design.

However, the above patent only solves the basic problem of shoe folding resistance testing, and does not fully consider the fixing stability and testing efficiency of shoes during the test. In actual applications, due to differences in shoe size and shape, traditional fixing methods are often difficult to adapt to various types of shoes, resulting in the possibility of sliding or offsetting of shoes during the test, affecting the accuracy of the test results.

[0018] The folding resistance testing machine for the shoe production line is provided with a fixing component in consideration of the fixing requirements of shoes of different sizes.

[0038] A driving gear 101 is provided at the bottom of the front side of the casing 1, and the input end of the driving gear 101 extends to the inner side of the casing 1. This design enables the folding tester to drive the driving gear to rotate through an external power source, thereby realizing the automatic operation of the entire tester, which not only improves the test efficiency, but also reduces the error of manual operation, and improves the accuracy and reliability of the test.

[0039] The top plate 2 extends to the outside of the housing 1 on both sides, and a pad with a threaded structure is provided on the top of the top plate 2. The top of the threaded cover 201 is integrally welded to the bottom of the top plate 2. The threads on the top plate 2 and the inner side of the threaded cover 201 adopt an external thread structure. This structural design facilitates the up and down adjustment of the threaded rod. Through the cooperation of the external thread structure, the lifting height of the threaded rod can be accurately controlled, thereby realizing fine adjustment of the position of the fixed component.

[0040] A handwheel is provided on the top of the threaded rod 3, and an internal thread structure is adopted on the outer side of the threaded rod 3. The internal thread structure on the outer side of the threaded rod 3 can fit tightly with the inner threads of the top plate 2 and the threaded cover 201.

[0041] The side pressure plate 403 in the fixing assembly 4 makes the side surfaces of the shoe pressure plate 401 in the same plane during the contraction process, and one end of the pressure rod 406 extends out of the bottom of the shoe pressure plate 401. The first spring member 402 is in a compressed state during the fitting process of the side pressure plate 403, and the second spring member 405 is in a relaxed state during the extension process of the pressure rod 406. This design ensures that the shoes can be firmly fixed during the test, avoiding test errors caused by unstable fixation. At the same time, the arrangement of the first spring member and the second spring member makes the fixing assembly have a certain elasticity, which can adapt to shoes of different sizes and improve the versatility of the testing machine.

[0042] A fixing rod 5 is provided on the inner side of the casing 1, and a placing plate 501 is equidistantly provided on the outer side of the fixing rod 5. Anti-slip grooves of a rectangular structure are equidistantly provided on the top of the placing plate 501. This design not only provides a stable supporting platform for the shoes, but also increases the friction between the shoes and the placing plate through the setting of the anti-slip grooves, further ensuring the stability of the shoes during the test process, which helps to reduce errors in the test process and improve the accuracy of the test.

[0043] The two ends of the outer side of the bottom rod 601 are provided with outwardly extending limit rings, and the outer side of the adjusting rod 602 is provided with an external thread structure. The two ends of the bottom rod 601 are fixedly connected to the connecting member 7 so that the connecting member 7 can drive the connecting member 7 to perform arc reciprocating movement during the arc movement. This design allows the adjusting rod to be accurately adjusted on the bottom rod to meet different test requirements. At the same time, the setting of the limit ring prevents the adjusting rod from falling off or shifting during the adjustment process, thereby ensuring the stability and safety of the test process.

[0044] One end of the connecting member 7 is provided with an auxiliary gear 701 extending to the outside of the housing 1. The outer tooth pattern of the auxiliary gear 701 fits with the driving gear 101, so that when the driving gear 101 moves, it can drive the auxiliary gear 701 to rotate, and at the same time drive the connecting member 7 to perform arc reciprocating movement. This design allows the driving gear to drive the auxiliary gear and the connecting member to perform arc reciprocating movement together when rotating, thereby realizing the automated operation of the bending assembly, which not only improves the test efficiency, but also ensures the continuity and stability of the test process.

[0045] A driving motor 8 is provided at the bottom of the inner side of the casing 1. The power input end of the driving motor 8 is connected to the external circuit equipment through a line. A transmission belt 801 is provided at the output end of the driving motor 8. One end of the transmission belt 801 is connected to the driving gear 101 and extends to one end of the inner side of the casing 1. This design allows the folding tester to be automatically operated through electric drive without manual intervention. This not only improves the test efficiency, but also reduces the labor intensity of the operator, and improves the overall performance and user experience of the tester. At the same time, the electric drive method is also more environmentally friendly and energy-saving, which is in line with the development trend of modern industry.

[0046] Working principle: First, the operation of the test machine starts with the power supply. The external circuit equipment provides a stable power input to the drive motor 8. As the core power source of the test machine, the drive motor 8 starts to operate efficiently once it receives power. In order to ensure the smooth transmission of power, a transmission belt 801 is connected to the output end of the drive motor 8. As a key component of power transmission, the transmission belt 801 transmits the rotational power generated by the drive motor 8 to the driving gear 101. The rotation of the driving gear 101 is the starting point for a series of subsequent actions. Its design ensures the efficient transmission and stability of power. The rotation of the driving gear 101 further drives the auxiliary gear 701, which is closely fitted with it, to rotate synchronously. The auxiliary gear 701 is connected to the connecting piece 7. This The design cleverly realizes the conversion and transmission of power. With the rotation of the auxiliary gear 701, the connecting piece 7 begins to perform arc reciprocating motion. This arc reciprocating motion provides necessary dynamic support for the subsequent bending test and ensures the continuity and stability of the test. The bending assembly 6 provided on the inner side of the connecting piece 7 is one of the key components of the testing machine. The bending assembly 6 includes core components such as the bottom rod 601, the adjusting rod 602 and the positioning rod 603. With the arc reciprocating motion of the connecting piece 7, the bending assembly 6 also begins to perform corresponding bending actions. In this process, the bottom rod 601 serves as the basic support for the bending action, and its stability and strength are crucial. The adjusting rod 602 provides precise control of the bending degree and strength. By adjusting the position of the adjusting rod 602, the bending degree and strength can be precisely controlled. In order to simulate various bending conditions that shoes may encounter in actual use, the positioning rod 603 ensures the accuracy and stability of the bending process and prevents the bending component from being offset or out of control. Before the test begins, the operator needs to perform a series of preparations on the testing machine, among which adjusting the position of the fixing component 4 is a crucial step. The fixing component 4 is responsible for firmly fixing the shoes during the test to ensure that they will not move or deform due to external forces. By rotating the handwheel, the operator can easily adjust the height of the threaded rod 3, thereby driving the fixing component 4 to move up and down to a suitable position. The precise threaded structure between the threaded rod 3 and the top plate 2 and the threaded cover 201 ensures the accuracy and stability of the adjustment, and can maintain a relatively high level even after long-term use. With high precision and reliability, the design of the fixing component 4 fully considers the fixing requirements of shoes of different sizes, and includes a plurality of key components such as a shoe pressure plate 401, a first spring member 402, and a side pressure plate 403. When the shoe pressure plate 401 touches the inside of the shoe, it compresses the second spring member and drives the pressure rod 406 to move inward. At the same time, the movement of the pressure rod 406 triggers the separation of the main buckle 407 and the side buckle 404. At this time, the side buckle 404 expands outward under the action of the compressed first spring member 402, driving the side pressure plate 403 to clamp and fix the two sides of the shoe. This design can not only adapt to shoes of different sizes, but also ensure that the shoe remains in a stable fixed state during the test process, thereby preventing test errors caused by unstable fixation.The bending assembly 6 performs a continuous bending action on the shoe, and the pressure and bending degree of the shoe can be flexibly adjusted through the adjusting rod 602 and the positioning rod 603. This adjustment can not only be customized according to different test requirements, but also simulate various complex situations that the shoe may encounter in actual use. At the same time, the limiting rings at both ends of the outer side of the bottom rod 601 ensure the stability and safety of the adjusting rod 602 during the adjustment process, and prevent the adjusting rod 602 from falling off or deviating. After the fixing assembly 4 fixes the shoe completely, the staff moves the adjusting plate 9 and the wrapping plate 901 downward, thereby utilizing the wrapping plate 9 01 Wrap the top of the shoes to ensure the integrity of the shoes during the test, avoid further damage or deformation of the shoes during the test, and protect the appearance and quality of the shoes. Wrapping protection can make the shoes more stable during the test, reduce the time of adjustment and fixation, and improve the test efficiency. The anti-slip pattern design on the surface of the placement plate 501 increases the friction between the shoes and the placement plate, preventing the shoes from sliding or deflecting during the test. The folding tester is fully automated through electric drive without manual intervention, which not only greatly improves the test efficiency, but also reduces the labor intensity of the operator. ,
