These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.
[0027] See also Figure 1 , which shows the main parts of the ball grinding device according to an embodiment of the utility model. Figure 1As shown, the ball grinding device Z of the present invention comprises a grinding device 1 and a control host 2. The grinding device 1 can be controlled by the control host 2 to perform a multi-stage grinding operation on at least one elastic ball, that is, the at least one elastic ball is ground to a target size in multiple stages in one grinding operation. The elastic ball is, for example, a rubber core of a golf ball, but the present invention is not limited thereto.
[0028] In the following, we will cooperate Figures 2 to 7 To describe the technical details of the grinding device 1 and the control host 2.
[0029] The grinding device 1 mainly includes a grinding roller 11, a pressure roller 12, a first driver 13 and a second driver 14. The grinding roller 11 and the pressure roller 12 are arranged opposite to each other, the first driver 13 is arranged to drive the pressure roller 12 to rotate at a working speed, and the second driver 14 is arranged to drive the pressure roller 12 to move closer to or away from the grinding roller 11. The control host 2 is electrically connected to the second driver 14 to control the second driver 14 to adjust the distance between the pressure roller 12 and the grinding roller 11.
[0030] In one optional or feasible embodiment of the present invention, the grinding roller 11 can be set as a roller grinding wheel, and the grinding roller 11 has a plurality of grinding grooves 11R arranged at intervals in the axial direction, wherein each grinding groove 11R can act on an elastic sphere B. The pressure roller 12 can be connected to the first driver 13 through a transmission shaft 131, and can rotate synchronously with the transmission shaft 131 under the drive of the first driver 13. In addition, the pressure roller 12 can be set on a multi-axis moving mechanism 15, and the multi-axis moving mechanism 15 is drivingly connected to the second driver 14. Therefore, the pressure roller 12 can reciprocate in the radial direction under the drive of the second driver 14, that is, approach or move away from the grinding roller 11. In addition, the pressure roller 12 can swing back and forth in the axial direction driven by the multi-axis moving mechanism 15 to improve the roundness of the elastic sphere B.
[0031] Furthermore, the multi-axis moving mechanism 15 can be configured as a combination of multiple linear slides, and can include a power source 151 to provide power for its reciprocating swing, but the present invention is not limited thereto.
[0032] In actual application, the grinding device 1 includes a grinding chamber 100, the grinding roller 11 and the pressure roller 12 are arranged in the grinding chamber 100, and the first driver 13 and the second driver 14 are arranged outside the grinding chamber 100. In addition, the grinding device 1 includes a support seat 16 arranged in the grinding chamber 100, the support seat 16 is located between the grinding roller 11 and the pressure roller 12 and has a plurality of oblique guide grooves 16R, and the plurality of oblique guide grooves 16R correspond to the positions of the plurality of grinding grooves 11R, so that each elastic ball B after grinding can move outward and leave the grinding chamber 100 under the guidance of the oblique guide grooves 16R.
[0033] like Figure 1 and Figure 3 As shown, the ball grinding device Z of the present invention may also include a ball feeding device 3 to continuously provide the elastic ball B to be ground into the grinding chamber 100. The ball feeding device 3 may include a conveying track 31 and a plurality of ball tubes 32 connected to the conveying track 31, and the plurality of ball tubes 32 are disposed in the grinding chamber 100. In addition, the plurality of ball tubes 32 are located above the support seat 16 and correspond to the positions of the plurality of inclined guide grooves 16R, wherein each of the ball tubes 32 can guide the elastic ball B into the grinding chamber 100 and drop it on the corresponding inclined guide groove 16R.
[0034] like Figures 3 to 5 As shown, the multi-stage grinding operation of the ball grinding equipment Z of the utility model for the elastic ball B (such as the rubber core of a golf ball) may include a first grinding operation, a second grinding operation and a third grinding operation in sequence. The grinding rate of the first grinding operation is greater than the grinding rate of the second grinding operation, and the grinding rate of the second grinding operation is greater than the grinding rate of the third grinding operation. In other words, the proportion of grinding away in the first stage is greater, while the proportion of grinding away in the second stage is less. The grinding rate is defined as: (grinded size-target size) / (initial size-target size). In actual application, the grinding rate of the first grinding operation may be between 20% and 85%, and may be optionally between 45% and 84%; the grinding rate of the second grinding operation may be between 20% and 40%, and may be optionally between 22% and 39%; the grinding rate of the third grinding operation may be less than 20%.
[0035] In addition, in the first grinding operation, the pressure roller 12 and the grinding roller 11 are separated by a first distance W1 to grind at least one elastic sphere B from an initial size to a first size. In the second grinding operation, the pressure roller 12 and the grinding roller 11 are separated by a second distance W2 to grind at least one elastic sphere B from a first size to a second size, the second distance W2 is smaller than the first distance W1, and the reduction rate of the second size relative to the target size is smaller than the reduction rate of the first size relative to the target size. In the third grinding operation, the pressure roller 12 and the grinding roller 11 are separated by a third distance W3 to grind at least one elastic sphere B from the second size to a third size, the third distance W3 is smaller than the second distance W2, and the reduction rate of the third size relative to the target size is smaller than the reduction rate of the second size relative to the target size. Therefore, the accuracy of the grinding process of the elastic sphere B can be improved, and the roundness of the elastic sphere B after grinding can be improved.
[0036] like Figure 2As shown, the control host 2 may include a display control interface 21, so that the on-site operator can set the operating parameters of each grinding stage through the display control interface 21, such as grinding time, size, retraction and pause time of the pressure roller 12, etc., and perform real-time monitoring in each grinding stage. Furthermore, in each grinding stage, in order to avoid accumulated errors, the movement of the pressure roller 12 is to retract first and then advance, that is, the pressure roller 12 first retracts to the waiting position and then advances to the new working position after staying for a set time.
[0037] It is worth noting that, although the above description uses three-stage grinding operation as an example to illustrate the features of the utility model, the spirit of the utility model can also be applied to grinding operations of more than three stages. For example, a five-stage grinding operation can be used for elastic balls of different materials, and the relative distance between the pressure roller 12 and the grinding roller 11 in the latter grinding operation is smaller than the relative distance between them in the former grinding operation, and the ball size reduction ratio obtained in the latter grinding operation is also smaller than the ball size reduction ratio obtained in the former grinding operation.
[0038] like Figure 1 and Figure 6 As shown, the ball grinding device Z of the utility model may also include an optical ruler 4 for measuring the moving distance of the pressure roller 12 relative to the grinding roller 11. Specifically, the second driver 14 includes a driving rod 141, and the free end of the driving rod 141 is connected to the pressure roller 12. The optical ruler 4 is arranged on one side of the driving rod 141, and the control host 2 is electrically connected to the optical ruler 4. Therefore, the optical ruler 4 can obtain the actual displacement data of the telescopic displacement of the driving rod 141, and transmit it to the control host 2 for interpretation and display.
[0039] Optionally, the second driver 14 is a servo driver, which can drive the multi-axis moving mechanism 15 to move the pressure roller 12 forward or backward a certain distance through the driving rod 141 according to set driving parameters such as driving direction and driving displacement, so as to achieve more precise grinding operation.
[0040] like Figure 7 As shown, the ball grinding device Z of the present invention may further include a ball washing device 5, and the ball washing device 5 is configured to use a cleaning liquid such as water to clean the at least one elastic ball B after grinding. Specifically, the ball washing device 5 may include a guide component 51 and a cleaning tank 52, and the cleaning tank 52 receives the at least one elastic ball B after grinding from the grinding chamber 100 through the guide component 51. The guide component 51 can be configured as a ball drop track, but the present invention is not limited thereto. According to actual needs, the ball washing device 5 may further include a sprayer 53 disposed above the cleaning tank 52.
