Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically a ball mill for coating production. Background Technology

[0002] In paint production, ball milling equipment is usually needed to grind the raw materials into fine powder for subsequent processing.

[0003] Currently used ball mills are quite heavy due to the presence of coatings and balls inside. Since ball mills primarily rely on gear transmission, the weight of the mill causes accelerated wear between the gears. After the gears fixed to the motor wear down to a certain extent, they need to be replaced. However, replacing gears is currently quite troublesome, requiring a lot of time to remove the screws that fix the gears, resulting in poor overall efficiency. Therefore, we propose a ball mill for coating production. Utility Model Content

[0004] The purpose of this invention is to provide a ball mill for coating production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ball mill for coating production, comprising a ball mill body, the ball mill body being composed of a base plate, a support, and a grinding barrel, the top of the base plate being provided with a driving device for driving the grinding barrel to rotate, the driving device being composed of a motor, a connecting shaft, a driving gear, and a driven gear, the connecting shaft being provided with a fixing component and a limiting component for fixing the driving gear;

[0006] The fixing component includes:

[0007] The locking block is used to cooperate with the fixing plate to restrict the drive gear from contact.

[0008] The control lever is used to control the movement of the locking block via the support rod;

[0009] The fixing rod is used to support the control rod;

[0010] The return spring is used to drive the control lever to reset.

[0011] Preferably, the motor is fixed to the top of the base plate, the output shaft of the motor is fixed to a connecting shaft, the drive gear is sleeved on the connecting shaft, the drive gear meshes with the driven gear, and the driven gear is fixed to the outer wall of the grinding barrel. The motor drives the connecting shaft and the drive gear to rotate, and the drive gear can control the rotation of the grinding barrel through the driven gear.

[0012] Preferably, the bracket is fixed to the top of the base plate, and the grinding barrel is rotatably connected to the bracket via a bearing. By putting the material into the grinding barrel, the grinding operation can be performed when the grinding barrel rotates.

[0013] Preferably, the fixing rod is fixed to the inner wall of the connecting shaft, the fixing rod passes through the control rod and is slidably connected to the control rod, a return spring is fixed to the left side of the control rod, the end of the return spring away from the control rod is fixed to the inner wall of the connecting shaft, a support rod is hinged to the outer wall of the control rod, the end of the support rod away from the control rod is hinged to the locking block, the locking block passes through the connecting shaft and is slidably connected to the connecting shaft, and the fixing plate is fixed to the outer wall of the connecting shaft. After the drive gear is sleeved on the connecting shaft, the drive gear abuts against the fixing plate, pushing the control rod to move to the left. The control rod can then push the locking block out from the connecting shaft through the support rod to abut against the side of the drive gear away from the fixing plate, thereby restricting the drive gear and fixing it. When the drive gear needs to be replaced, after releasing the restriction on the control rod, the control rod can move to the right under the action of the return spring. The control rod pulls the locking block into the connecting shaft through the support rod, thereby releasing the restriction on the drive gear. At this time, the drive gear can be removed for replacement, effectively improving the efficiency of replacing the drive gear.

[0014] Preferably, the limiting component includes a vertical rod, one end of which is fixed to the outer wall of the control rod, and the other end of which passes through and is slidably connected to the chuck. A connecting spring is fixed to the end of the chuck near the vertical rod, and the end of the connecting spring away from the chuck is fixed to the outer wall of the control rod. An L-shaped rod is fixed to the inner wall of the connecting shaft, and a locking block is fixed to the end of the L-shaped rod away from the inner wall of the connecting shaft. The L-shaped rod passes through and is slidably connected to the slider, and a tension spring is fixed to the end of the slider away from the locking block. The end of the tension spring away from the slider is fixed to the L-shaped rod. When the control rod is pushed to the left to control the locking block and limit the drive gear, the control rod moves together with the vertical rod and the chuck. When the chuck contacts the locking block, the chuck is first pushed away from the locking block and moves to the side away from the locking block. After the chuck moves to the left side of the locking block, the chuck can spring back under the action of the connecting spring. The lever is positioned on the left side of the locking block to restrict its movement. To release the control lever, simply push it to the left again. The lever, along with the vertical rod and the locking blade, moves to the left. When the locking blade contacts the slider, it is initially pushed away from the slider. Once the locking blade reaches the left side of the slider, it springs up and contacts the left side of the slider. At this point, release the control lever. The lever, along with the vertical rod and the locking blade, moves to the right. The locking blade, in contact with the slider, moves to the right. When the slider and the locking block are in contact, the locking blade moves along the left side of the slider towards the control lever until it separates from the slider and the locking block, releasing the control lever's restriction. The control lever then resets under the action of the reset spring. Once the slider is no longer in contact, it resets to the left under the action of the tension spring, completing the device's reset.

[0015] Preferably, a protruding pin is fixed to the top of the connecting shaft, and a hole is provided on the drive gear to engage with the protruding pin. When the connecting shaft rotates, the protruding pin can stably resist the rotation of the drive gear.

[0016] Compared with the prior art, this utility model provides a ball mill for coating production, which has the following beneficial effects:

[0017] 1. This ball mill for coating production, through its fixed and limiting components, allows for easy replacement of the drive gear. Simply release the control lever after it is restricted, and the control lever will move to the right under the action of the return spring. The control lever then pulls the locking block into the connecting shaft via the support rod, thus releasing the restriction on the drive gear. The drive gear can then be removed and replaced, effectively improving the efficiency of drive gear replacement.

[0018] 2. This ball mill for coating production, after the drive gear is sleeved on the connecting shaft, the drive gear abuts against the fixed plate, and the control rod is pushed to move to the left. The control rod can then push the locking block out from the connecting shaft through the support rod to abut against the side of the drive gear away from the fixed plate, thereby restricting the drive gear and fixing it. The operation is convenient. Attached Figure Description

[0026] like Figures 1-6 As shown, this utility model provides a technical solution: a ball mill for paint production, including a ball mill body 1. The ball mill body 1 is composed of a base plate 101, a support 102 and a grinding barrel 103. The top of the base plate 101 is provided with a driving device for driving the grinding barrel 103 to rotate. The driving device is composed of a motor 4, a connecting shaft 5, a driving gear 6 and a driven gear 7. The connecting shaft 5 is provided with a fixing component 2 and a limiting component 3 for fixing the driving gear 6. The fixing component 2 includes: a locking block 21, a fixing plate 22, a control rod 23, a support rod 24, a fixing rod 25 and a return spring 26.

[0027] The motor 4 is fixed to the top of the base plate 101. The output shaft of the motor 4 is fixed with the connecting shaft 5. The drive gear 6 is sleeved on the connecting shaft 5. The drive gear 6 meshes with the driven gear 7. The driven gear 7 is fixed to the outer wall of the grinding barrel 103. The motor 4 drives the connecting shaft 5 and the drive gear 6 to rotate. The drive gear 6 can control the rotation of the grinding barrel 103 through the driven gear 7.

[0028] The support 102 is fixed to the top of the base plate 101. The grinding barrel 103 is rotatably connected to the support 102 through a bearing. By putting the material into the grinding barrel 103, the grinding operation can be carried out when the grinding barrel 103 rotates.

[0029] A fixing rod 25 is fixed to the inner wall of the connecting shaft 5. The fixing rod 25 passes through the control rod 23 and is slidably connected to the control rod 23. A return spring 26 is fixed to the left side of the control rod 23. The end of the return spring 26 away from the control rod 23 is fixed to the inner wall of the connecting shaft 5. A support rod 24 is hinged to the outer wall of the control rod 23. The end of the support rod 24 away from the control rod 23 is hinged to the locking block 21. The locking block 21 passes through the connecting shaft 5 and is slidably connected to the connecting shaft 5. A fixing plate 22 is fixed to the outer wall of the connecting shaft 5. After the drive gear 6 is sleeved on the connecting shaft 5, the drive gear 6 abuts against the fixing plate 22, pushing the control rod 23 to the left. When the control lever 23 is moved, it can push the locking block 21 through the support rod 24 to extend from the connecting shaft 5 and abut against the side of the drive gear 6 away from the fixed plate 22, thereby restricting the drive gear 6 and fixing it. When the drive gear 6 needs to be replaced, after the restriction on the control lever 23 is released, the control lever 23 can move to the right under the action of the return spring 26. The control lever 23 pulls the locking block 21 into the connecting shaft 5 through the support rod 24, thereby releasing the restriction on the drive gear 6. At this time, the drive gear 6 can be removed and replaced, which effectively improves the efficiency of replacing the drive gear 6.

[0030] The limiting component 3 includes a vertical rod 31, one end of which is fixed to the outer wall of the control rod 23, and the other end of which passes through and is slidably connected to the chuck 32. A connecting spring 33 is fixed to the end of the chuck 32 near the vertical rod 31, and the end of the connecting spring 33 away from the chuck 32 is fixed to the outer wall of the control rod 23. An L-shaped rod 34 is fixed to the inner wall of the connecting shaft 5, and a locking block 35 is fixed to the end of the L-shaped rod 34 away from the inner wall of the connecting shaft 5. The L-shaped rod 34 passes through and is slidably connected to the slider 36. The slider 36 is slidably connected to the slider 36 away from the inner wall of the connecting shaft 5. A tension spring 37 is fixed to one end of the locking block 35. The end of the tension spring 37 away from the slider 36 is fixed to the L-shaped rod 34. When the control lever 23 is pushed to the left to control the locking block 21 to restrict the drive gear 6, the control lever 23 moves together with the vertical rod 31 and the locking knife 32. When the locking knife 32 contacts the locking block 35, the locking knife 32 is first pushed away from the locking block 35 and moves to the side away from the locking block 35. After the locking knife 32 moves to the left side of the locking block 35, the locking knife 32 can be ejected under the action of the connecting spring 33 and contact the locking block 35. To restrict the control lever 23, push it to the left again. The control lever 23, along with the vertical rod 31 and the clamping knife 32, moves to the left. When the clamping knife 32 contacts the slider 36, it is first pushed away from the slider 36. When the clamping knife 32 reaches the left side of the slider 36, it springs up and contacts the left side of the slider 36. Releasing the control lever 23 allows it to move to the right under the action of the return spring 26. 3. Move the vertical rod 31 and the clamping knife 32 to the right together. The clamping knife 32 moves to the right against the slider 36. When the slider 36 and the clamping block 35 are in contact, the clamping knife 32 can move along the left slope of the slider 36 towards the control rod 23 until the clamping knife 32 separates from the slider 36 and the clamping block 35, thereby releasing the limit on the control rod 23. At this time, the control rod 23 can be reset under the action of the return spring 26, and after the slider 36 is no longer in contact, it can be reset to the left under the action of the tension spring 37, thus completing the reset of the device.

[0031] A protruding pin 8 is fixed to the top of the connecting shaft 5, and a hole is opened on the drive gear 6 to match the protruding pin 8. When the connecting shaft 5 rotates, the protruding pin 8 can stably resist the rotation of the drive gear 6.

[0032] When in use, after putting the material to be ground into the grinding barrel 103, start the motor 4. The motor 4 drives the drive gear 6 to rotate through the connecting shaft 5. The drive gear 6 drives the grinding barrel 103 to rotate through the driven gear 7 to perform the grinding operation.

[0033] When the drive gear 6 needs to be replaced after prolonged use, simply push the control lever 23 to the left. The control lever 23, along with the vertical lever 31 and the chuck 32, will move to the left. When the chuck 32 contacts the slider 36, it will first be pushed away from the slider 36. When the chuck 32 moves to the left side of the slider 36, it will spring up and contact the left side of the slider 36. At this point, release the control lever 23. The control lever 23 will then move to the right under the action of the return spring 26. The vertical rod 31 and the chuck 32 move to the right together. The chuck 32 moves to the right against the slider 36. When the slider 36 and the chuck 35 are in contact, the chuck 32 can move along the left side of the slider 36 towards the control rod 23 until the chuck 32 separates from the slider 36 and the chuck 35, thus releasing the limit on the control rod 23. At this time, the control rod 23 can be reset under the action of the reset spring 26, and after the slider 36 is no longer in contact, it can be reset to the left under the action of the tension spring 37.

[0034] When the control lever 23 is reset, it pulls the locking block 21 into the connecting shaft 5 through the support rod 24, thereby releasing the restriction on the drive gear 6. At this time, the drive gear 6 can be removed and replaced, which effectively improves the efficiency of replacing the drive gear 6.

[0035] When replacing the new drive gear 6, insert the new drive gear 6 into the protruding pin 8 on the connecting shaft 5, so that the drive gear 6 abuts against the fixing plate 22. Push the control lever 23 to move to the left. The control lever 23 can then push the locking block 21 out of the connecting shaft 5 through the support rod 24 to abut against the side of the drive gear 6 away from the fixing plate 22, thereby restricting the drive gear 6 and fixing it. At the same time, the control lever 23 moves together with the vertical rod 31 and the locking knife 32. When the locking knife 32 abuts against the locking block 35, the locking knife 32 is first abutted against by the locking block 35 and moves to the side away from the locking block 35. When the locking knife 32 moves to the left side of the locking block 35, the locking knife 32 can be ejected under the action of the connecting spring 33 and abut against the left side of the locking block 35, thereby restricting the control lever 23.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
