When the adjusting screw 202 is rotated, the adjusting screw 202 can move inside the tensioning seat 201 through the rod body thread. When the adjusting screw 202 moves, it can drive the control rod 203 to move synchronously to change the use position, thereby changing the compression degree of the tensioning top spring 2011 when the lifting rod 2051 enters the lifting groove 2032, that is, the grinding pressure, which can adapt to the grinding processing operations of different molds and has strong adaptability.

[0026] In the embodiment of the present disclosure, a tensioning top spring 2011 is provided on the side of the tensioning seat 201, and the two ends of the tensioning top spring 2011 respectively abut against the side of the tensioning seat 201 and the side of the positioning seat 204, a positioning top spring 1021 is provided on the top of the positioning block 102, and the two ends of the positioning top spring 1021 respectively abut against the inside of the positioning block 102 and the inside of the mounting seat 101, and a positioning slot 2041 is provided on the top of the positioning seat 204. Under the action of the positioning top spring 1021, the bottom of the positioning block 102 is inserted into the inside of the positioning slot 2041. In use, when the tensioning assembly 2 is in normal use, the positioning block 102 is positioned under the action of the positioning top spring 1021. The bottom of 102 is inserted into the interior of the positioning slot 2041, so that the positioning seat 204 cannot move inside the mounting seat 101 to change the use position, and at this time, under the action of the tensioning top spring 2011, the tensioning seat 201 can tension the grinding belt through the driven wheel 206 to realize the grinding operation of the mold. When grinding, the power of the driving motor 104 is turned on, and the rotating shaft of the driving motor 104 can drive the active wheel 103 to rotate.

In use, the tensioning assembly 2 has a protective function for the grinding belt, that is, when the grinding pressure is too large, the tensioning assembly 2 can remove the pressure and tensioning force acting on the grinding belt, so that It can effectively avoid the phenomenon that the grinding belt is torn due to excessive force. During the grinding process, the grinding belt will contact the mold. The greater the grinding pressure, the grinding belt will be deformed and the driven wheel 206 will move toward the direction close to the active wheel 103 and compress the tensioning top spring 2011. The driven wheel 206 can drive the tensioning seat 201 to move synchronously when moving. The tensioning seat 201 can drive the control rod 203 to move synchronously when moving by adjusting the screw 202, thereby triggering the protection function of the tensioning assembly 2 through the movement of the control rod 203.

[0028] In the embodiment of the present disclosure, the push block 205 is located inside the positioning slot 2041, and when the lifting rod 2051 is located inside the hidden slot 2031, the highest position of the push block 205 is lower than the highest position of the positioning slot 2041. In use, when the control rod 203 moves, the lifting rod 2051 will first move relatively inside the hidden slot 2031. At this time, the push block 205 will not change in height inside the positioning seat 204, so that the bottom of the positioning block 102 can be stably plugged into the positioning slot 2041 to ensure the normal use of the tensioning function. After entering the interior of the lifting groove 2032, the pushing block 205 will move upward under the guidance of the lifting groove 2032 to push the positioning block 102 out of the interior of the positioning groove 2041. Thereafter, the positioning seat 204 will move in the direction away from the tensioning seat 201 under the action of the tensioning top spring 2011, so that the tensioning top spring 2011 is extended, that is, the tensioning force and grinding pressure are relieved, thereby preventing the grinding belt from being damaged due to excessive grinding pressure. Thereafter, the tensioning assembly 2 can be reset by manually pushing the positioning seat 204 in the direction close to the tensioning seat 201 to prepare for subsequent grinding operations.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In the utility model, after holding the handle and turning on the drive motor 104, the mold can be started to be polished. When the tensioning component 2 is in normal use, the bottom of the positioning block 102 is inserted into the inside of the positioning slot 2041 under the action of the positioning top spring 1021, so that the positioning seat 204 cannot move inside the mounting seat 101 to change the use position, and at this time, under the action of the tensioning top spring 2011, the tensioning seat 201 can tension the polishing belt through the driven wheel 206 to realize the polishing operation of the mold. When polishing, the power supply of the drive motor 104 is turned on, and the rotating shaft of the drive motor 104 can drive the driving wheel 103 to rotate. When the driving wheel 103 rotates, it can cooperate with the driven wheel 206 to make the polishing belt move at high speed. The operation of the grinding device 206 is the same as that of the traditional belt grinding device, and it is easy to use. The tensioning component 2 has a protective function for the grinding belt, that is, when the grinding pressure is too large, the tensioning component 2 can remove the pressure and tensioning force acting on the grinding belt, thereby effectively avoiding the phenomenon of the grinding belt being torn due to excessive force. During the grinding process, the grinding belt will contact the mold. The greater the grinding pressure, the deformation of the grinding belt will cause the driven wheel 206 to move toward the direction close to the driving wheel 103 and compress the tensioning top spring 2011. The driven wheel 206 can drive the tensioning seat 201 to move synchronously when moving. The tensioning seat 201 can drive the control rod 203 to move synchronously by adjusting the screw 202 when moving, so as to control the control rod 203 through the control rod 202. 03 is moved to trigger the protection function of the tensioning assembly 2. When the control rod 203 moves, the lifting rod 2051 will first move relatively inside the hidden groove 2031. At this time, the pushing block 205 will not change its height inside the positioning seat 204, so that the bottom of the positioning block 102 can be stably inserted into the positioning slot 2041 to ensure the normal use of the tensioning function. When the lifting rod 2051 enters the lifting slot 2032, the pushing block 205 will move upward under the guidance of the lifting slot 2032 to push the positioning block 102 out of the positioning slot 2041. Thereafter, the positioning seat 204 will move in a direction away from the tensioning seat 201 under the action of the tensioning top spring 2011, so that the tensioning top spring 2011 is stretched. When the adjusting screw 202 is rotated, the adjusting screw 202 can move inside the tensioning seat 201 through the rod body thread. When the adjusting screw 202 moves, it can drive the control rod 203 to move synchronously and change the use position, thereby changing the compression degree of the tensioning top spring 2011 when the lifting rod 2051 enters the lifting groove 2032, that is, the grinding pressure, which can adapt to the grinding processing operations of different molds.
