DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] See also Figure 1 and Figure 2 , a preparation process of a polyurethane elastomer material, comprising the following steps:

[0036] S1. Mould making: Make corresponding sole mould according to the design requirements of the sole.

[0037] S2. Preparation of fillers: polyurethane raw materials are mixed in a certain ratio, reacted under certain conditions to form a polyurethane prepolymer, and pigments and fillers are added to the prepolymer, and the fillers are obtained after being fully mixed.

[0038] S3, injection molding: inject the mixed filler into the sole mold made in step S1 by injection molding, and solidify and mold after a certain period of time.

[0039] S4, post-molding treatment: demoulding, trimming and cleaning the molded sole to obtain a polyurethane elastomer sole.

[0040] S5. Quality testing: The obtained polyurethane elastomer sole is subjected to quality testing by using performance testing equipment.

[0041] The S5 quality inspection process involves performance inspection equipment, wherein the performance inspection equipment includes a workbench base 1, and a vertical plate 11 is fixedly connected to the rear side of the upper end of the workbench base 1; a swing mechanism 2 is arranged on the front side of the vertical plate 11; a positioning clamping mechanism 3 is arranged below the swing mechanism 2, and is used for limiting the clamping of the polyurethane elastomer sole; a simulation table mechanism 4 is arranged in a groove 12 opened in the workbench base 1, and is used for performance inspection of the polyurethane elastomer sole, and the simulation table mechanism 4 includes a moving table 41 slidably connected in the groove 12, and a placement groove 411 is opened at the upper end of the moving table 41, and a positioning rod 412 is fixedly connected to the bottom end of the placement groove 411, and a road surface simulation block 5 is placed in the placement groove 411.

[0042] During operation, the polyurethane elastomer sole is placed on the positioning and clamping mechanism 3 for clamping, and the road surface simulation block 5 is placed on the simulation platform mechanism 4. It should be noted here that there are multiple road surface simulation blocks 5, and each road surface simulation block 5 has the same structure. The upper end surface is composed of a variety of different materials, such as cement surface, wooden surface, floor tile surface, gravel surface, etc., so as to facilitate the simulation of different road surfaces and observe the wear degree of the polyurethane elastomer sole on different road surfaces to detect the influence of different road surfaces on the quality of the polyurethane elastomer sole. Under the same road surface simulation block 5, the reciprocating speed of the simulation platform mechanism 4 can also be adjusted to simulate the wear degree of the polyurethane elastomer sole caused by the change of walking speed on the same road surface to detect the influence of different speeds on the quality of the polyurethane elastomer sole. At the same time, the swing mechanism 2 is started to drive the positioning and clamping mechanism 3 to swing back and forth, thereby driving the polyurethane elastomer sole to reciprocate and rub on the upper end surface of the road surface simulation block 5 that moves back and forth left and right.

[0043] Continue reading Figure 1 and Figure 2 The swing mechanism 2 includes a rotating disk 21 rotatably connected to the vertical plate 11, the rotating shaft of the rotating disk 21 passes through the vertical plate 11 and is connected to the second motor, a connecting column 22 is fixedly connected to the front side of the rotating disk 21 away from the center, a limiting column 23 is fixedly connected to the front side of the vertical plate 11 and below the rotating disk 21, a swing rod 24 is rotatably connected to the limiting column 23, a clearance groove 241 is opened on the swing rod 24, the connecting column 22 is slidably connected in the clearance groove 241, and a swing frame 25 is fixedly connected to the bottom end of the swing rod 24.

[0044] During operation, the second motor is started to drive the rotating disk 21 to rotate on the vertical plate 11, and the connecting column 22 on the rotating disk 21 will drive the swing rod 24 to swing back and forth around the limit column 23, and the swing rod 24 will then drive the swing frame 25 to swing synchronously.

[0045] Continue reading Figure 3 and Figure 4 A through groove is provided inside the swing frame 25 and the opening of the through groove is set downward. Side grooves 26 connected to the through groove are provided on the left and right sides of the swing frame 25. The side grooves 26 are set so as not to hinder the normal rotation of the arc gear 36. Guide rods 27 are fixedly connected to the front and rear sides of the through groove of the swing frame 25. The positioning and clamping mechanism 3 includes a third motor fixedly connected to the top of the through slot, the third motor is connected to a threaded rod 31, the threaded rod 31 is threadedly connected to a threaded hole opened at the top of the moving rod 32, the front and rear ends of the moving rod 32 are both provided with rectangular slots 33, the guide rod 27 in the through slot is slidably connected in the rectangular slot 33, the left and right sides of the moving rod 32 are both provided with gear teeth 34 evenly arranged up and down, the gear teeth 34 are meshed with a transition gear 35, the transition gear 35 is rotatably connected in the through slot, the transition gear 35 is meshed with an arc gear 36, the arc gear 36 is also rotatably connected in the through slot, the other side of the arc gear 36 is fixedly connected to an extension rod 37, the bottom ends of the moving rod 32 and the extension rod 37 are both provided with an adsorption assembly 38.

[0046] During operation, when it is necessary to position and clamp the polyurethane elastomer sole, the two ends of the polyurethane elastomer sole are respectively placed between the extension rods 37 on both sides, and the third motor is started to drive the threaded rod 31 to rotate in the moving rod 32. Since the moving rod 32 can only move up and down in the through groove under the action of the guide rod 27, when the threaded rod 31 rotates, it will drive the moving rod 32 to move downward. During the downward movement of the moving rod 32, the gear teeth 34 on both sides will engage the transition gear 35 to rotate, and the rotation of the transition gear 35 will drive the arc gear 36 to rotate. The arc gears 36 on both sides synchronously drive the extension rods 37 to rotate closer. When the bottom end of the moving rod 32 contacts the upper end of the polyurethane elastomer sole, the extension rods 37 on both sides will also contact the two ends of the polyurethane elastomer sole until the polyurethane elastomer sole is positioned and clamped at three positions.

[0047] See also Figure 3 and Figure 6 The adsorption component 38 includes a connecting block 381 fixedly connected to the bottom end of the moving rod 32. The connecting block 381 on the moving rod 32 is a rectangular structure. The left and right extension rods 37 are symmetrically provided with clamping blocks 382. The clamping blocks 382 are arc-shaped structures. A plurality of cylindrical grooves 383 are evenly opened at the bottom end of the connecting block 381. A suction cup 385 is fixedly connected to the cylindrical groove 383 through a compression spring 384. The opposite sides of the two clamping blocks 382 are provided with the same structure as the bottom end of the connecting block 381.

[0048] During operation, when the connecting block 381 and the clamping block 382 contact the polyurethane elastomer sole, multiple suction cups 385 will adsorb the contact surface. Since the contact surface with the polyurethane elastomer sole is uneven, the suction cup 385 can adaptively adjust the contact height with the polyurethane elastomer sole under the action of the compression spring 384. The setting of multiple suction cups 385 makes the adsorption of the polyurethane elastomer sole more stable.

[0049] Continue to refer to the attached Figure 3 and Figure 5 , wherein, extension columns 42 are integrally formed on the left and right sides of the bottom end of the moving platform 41, and balls 43 are rotatably set at the bottom ends of the two extension columns 42. The balls 43 are rotatably set in the limit grooves 13 connected to the bottom end of the groove 12. One side of the moving platform 41 located on the left and right sides is fixedly connected to the inner wall of the groove 12 through a tension spring 44, and the other side of the moving platform 41 is contacted with a cam 45. One end of the rotating shaft of the cam 45 is rotatably connected to the electric slider 46, and the other end of the rotating shaft of the cam 45 is connected to the first motor, and the first motor is fixedly connected to the moving slider 47. The electric slider 46 and the moving slider 47 are respectively slidably connected to the moving grooves 14 opened on the front and rear inner walls of the groove 12.

[0050] During operation, under the natural force of the tension spring 44, the end of the cam 45 away from the protrusion contacts one side of the moving platform 41, and the first motor is started to drive the cam 45 to rotate. Under the action of the ball 43, the moving platform 41 moves back and forth left and right in the groove 12 to simulate the fast walking mode. When the electric slider 46 is started, the cam 45 is driven to move in the direction away from the moving platform 41, but at this time, the end of the cam 45 away from the protrusion cannot contact the moving platform 41, but the protruding end of the cam 45 will still contact the moving platform 41, and the first motor is started again. At this time, the reciprocating speed of the moving platform 41 is slower than the previous moving speed, simulating the slow walking mode, so as to realize the movement at different speeds to perform quality inspection on the polyurethane elastomer sole. It should be noted here that the swing direction of the swing frame 25 is always in the opposite direction to the movement direction of the moving platform 41.

[0051] Continue reading Figure 7 , Figure 8 , Fig. 9 and Fig.10 A positioning groove 51 is provided at the bottom end of the road simulation block 5 corresponding to the position of the positioning rod 412, and a clamping groove 52 is provided on the left and right sides of the road simulation block 5. A shift block 53 is fixedly connected to the upper and lower sides of the notch of the clamping groove 52 and close to the rear side. A toggle groove 413 connected to the placement groove 411 is provided on the left and right sides of the moving platform 41, and a clamping assembly 414 is arranged in the toggle groove 413.

[0052] The snap-on assembly 414 includes a moving frame 4141 slidably connected in the toggle slot 413, and a snap-on block 4143 is connected to the moving frame 4141 via a tension spring 4142. The opposite sides of the snap-on blocks 4143 on both sides are V-shaped elastic structures, and the V-shaped elastic structure is fixedly connected to the column structure. The front side of the moving frame 4141 is fixedly connected to a connecting spring 4144.

[0053] During operation, when it is necessary to install and clamp different road simulation blocks 5, a road simulation block 5 of corresponding material is selected, and the clamping block 4143 on the moving platform 41 is first moved in a direction away from the toggle slot 413, and the tension spring 4142 will be squeezed. In this state, the V-shaped elastic structure of the clamping block 4143 will not block the movement of the road simulation block 5, and at the same time, the clamping block 4143 is moved in the direction of the connecting spring 4144, driving the moving frame 4141 to move synchronously in the direction of the connecting spring 4144, and the connecting spring 4144 will be in a squeezed state. At this time, the road simulation block 5 is moved to the placement slot 411, and the positioning slot 51 is correspondingly inserted into the positioning rod 41 2, perform preliminary limiting, then move the clamping block 4143 in the direction of the toggle slot 413, one end of the V-shaped elastic structure of the clamping block 4143 will enter the clamping slots 52 on the left and right sides of the road simulation block 5, and the tension spring 4142 will return to its natural state, and then move the clamping block 4143 away from the connecting spring 4144, the V-shaped elastic structure of the clamping block 4143 will enter the position where the stop block 53 is located at the notch of the clamping slot 52, at this time the connecting spring 4144 is in its natural state, the stop block 53 will limit the V-shaped elastic structure of the clamping block 4143, thereby realizing the limiting and fixing of the road simulation block 5 by the clamping assembly 414.
