Description

Technical Field

[0001] The utility model mainly relates to the field of masterbatch production, and particularly relates to an instrument for accurately measuring the friction coefficient of masterbatch. Background Technique

[0002] Silicone masterbatch, also known as masterbatch and masterbatch paste, is used for coloring various silicone products, suitable for the compression molding process, and is an essential raw material for coloring silicone products. Silicone masterbatch is a silicone masterbatch prepared by mixing special silicone raw rubber with various color powders and a variety of additives, used for coloring various silicone products, suitable for the compression molding process, and is divided into organic masterbatch, organic fluorescent masterbatch, and inorganic masterbatch according to the main properties;

[0003] The friction coefficient refers to the ratio of the frictional force between two surfaces to the vertical force acting on one of the surfaces, that is, the friction coefficient = frictional force ÷ vertical force. It is related to the roughness of the surface and has nothing to do with the size of the contact area. According to the nature of the motion, it can be divided into dynamic friction coefficient and static friction coefficient. Sliding friction is generated when two objects come into contact and slide relative to each other;

[0004] The reason why the masterbatch needs to measure the friction coefficient is that the size of the friction coefficient is directly related to the performance of the masterbatch during production and use. The masterbatch is detected by a friction coefficient tester.

[0005] The inventor found the following defects during the operation of the specific embodiment:

[0006] However, when the friction coefficient tester detects the friction coefficient of the masterbatch, the masterbatch slides inside the friction coefficient tester. However, this method can only detect the same type of masterbatch and cannot detect the friction coefficient of different types of masterbatch simultaneously according to production needs.

[0007] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0030] Refer to the attached Figures 1 - 3 , an instrument for accurately measuring the coefficient of friction of masterbatch, comprising an angle adjustment structure 1, a placement structure 2 is rotatably connected to the top of the angle adjustment structure 1, and a limiting structure 3 is arranged on the top of the placement structure 2;

[0031] The placement structure 2 includes a rotating shaft 201, a placement rack 202 is arranged on one side of the rotating shaft 201, guiding strips 203 are arranged on the outer walls on both sides of the placement rack 202, a placement groove 204 is opened on the top of the placement rack 202, the number of the placement grooves 204 is set to be multiple, and the multiple placement grooves 204 are equidistantly distributed on the top of the placement rack 202. Contact sensors 205 are arranged on both sides of the placement groove 204. When it is necessary to detect the coefficient of friction of the masterbatch, place the masterbatch at one end of the placement groove 204 and make it fit with the limiting plate 304, then start the motor. The motor drives the transmission lead screw 103 to rotate, the transmission lead screw 103 drives the moving block 108 to move, and the moving block 108 pushes the placement rack 202 to rotate along the connection position between the rotating shaft 201 and the connection block 104 through the push rod 109. And the guiding strips 203 on the outer wall of the placement rack 202 slide on the inner wall of the guiding groove 107. Then pull the limiting structure 3 outwards, the limiting plate 304 disengages from the masterbatch, so that the masterbatch slides on the inner wall of the placement groove 204. After the contact sensor 205 at one end where the masterbatch disengages slides, it contacts the contact sensor 205 at the other end. Calculate the sliding time of the masterbatch. The inclined plane angle when the masterbatch starts to slide is the friction angle, and the coefficient of friction can be calculated through the tangent value of the friction angle.

[0032] Further, the angle adjustment structure 1 includes a mounting plate 101. An installation groove 102 is formed in the middle of the top of the mounting plate 101. A transmission lead screw 103 is rotatably connected inside the installation groove 102. A moving block 108 is arranged on the outer wall of the transmission lead screw 103. The moving block 108 is slidably connected to the installation groove 102. A push rod 109 is rotatably connected to the top of the moving block 108. One end of the push rod 109 is rotatably connected to the bottom of the placement rack 202. When the motor is started, the motor drives the transmission lead screw 103 to rotate. The transmission lead screw 103 drives the moving block 108 on the outer wall to move, causing the moving block 108 to drive the push rod 109 to move. Then the push rod 109 pushes the placement structure 2 to rotate for adjusting the angle of the placement structure 2.

[0033] Further, a connecting block 104 is arranged at one end of the top of the mounting plate 101. A connecting groove 105 is formed inside the connecting block 104. A guiding ring 106 is arranged at the top of the connecting groove 105. A guiding groove 107 is formed inside the guiding ring 106. The guiding groove 107 is slidably connected to a guiding strip 203. The connecting groove 105 is rotatably connected to a rotating shaft 201. When the rotating shaft 201 rotates, the rotating shaft 201 rotates on the inner wall of the connecting groove 105. At the same time, the guiding strip 203 slides on the inner wall of the guiding groove 107. While the guiding groove 107 limits the angle of the placement rack 202, a scale is arranged on the outer wall of the guiding ring 106, and the rotation angle of the placement rack 202 can be seen.

[0034] Further, a bracket 206 is arranged at the top of the placement rack 202. A vision sensor 207 is arranged at the bottom of the bracket 206. Mounting holes 208 are formed on both sides of the bracket 206. Whether the color masterbatch placed inside the placement groove 204 slides can be detected by the provided vision sensor 207. When no color masterbatch passes through the vision sensor 207 and the color masterbatch at other positions contacts the contact sensor 205, the placement rack 202 continues to rotate by a certain angle so that the subsequent color masterbatch can slide on the inner wall of the placement groove 204.

[0035] Further, the limiting structure 3 includes a slide bar 301 slidably connected inside the mounting hole 208. A return spring 302 is arranged between the slide bar 301 and the mounting hole 208. A top plate 303 is arranged at the bottom of the slide bar 301. A limiting plate 304 is arranged at the bottom of the top plate 303. The limiting plate 304 aligns with the placement groove 204. When the top plate 303 is pulled upward, the top plate 303 drives the limiting plate 304 to disengage from the placement groove 204 and release the limitation on the color masterbatch, enabling the color masterbatch to slide inside the placement groove 204.

[0036] The above-described embodiments merely represent certain implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
