Detailed Embodiments

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, an embodiment of the present invention provides a mold humidifying device for applying clean water to the surface of the mold after curing to replenish moisture to the mold and prevent the mold from drying out and becoming brittle.

[0023] Please refer to Figure 1 and Figure 2 The mold humidifying device includes a frame 1, and a first guide roller 11 and a second guide roller 12 are respectively provided on opposite sides of the frame 1. The first guide roller 11 and the second guide roller 12 are respectively in contact with the mold and guide the mold to move on the frame 1. A water absorption roller 2, a water dipping roller 3 and a pressure roller 4 are sequentially provided between the first guide roller 11 and the second guide roller 12 along the conveying direction of the mold, wherein the water absorption roller 2 is covered with a water absorption layer 21, the water dipping roller 3 is covered with a flexible layer 31 and the flexible layer 31 is in contact with the water absorption layer 21, the pressure roller 4 is located on the side of the water dipping roller 3 away from the water absorption roller 2, and there is a gap between the pressure roller 4 and the water dipping roller 3 for the mold to pass through, and a water trough 5 is also provided on the frame 1. The water trough 5 is located below the water absorption roller 2 and part of the water absorption layer 21 extends into the water trough 5, and the water in the water trough 5 is stored Clean water is supplied to the water-absorbing layer 21 extending into the water trough 5 for absorption. The frame 1 is further provided with a first driving member connected to the water-absorbing roller 2 and a second driving member connected to the water-dipping roller 3. The direction in which the first driving member drives the water-absorbing roller 2 to rotate is opposite to the direction in which the second driving member drives the water-dipping roller 3 to rotate. Through the continuous rotation of the water-absorbing roller 2 and the water-dipping roller 3, the clean water absorbed by the water-absorbing layer 21 can be evenly applied to the flexible layer 31, and when the abrasive tool passes through the gap between the water-dipping roller 3 and the pressure roller 4, the clean water attached to the flexible layer 31 is applied to the surface of the abrasive tool.

[0024] Specifically, the operating steps for humidifying the abrasive tool using the abrasive tool humidifying device provided in this embodiment are as follows: Unroll the abrasive tool and pass it through the gap between the water-absorbing roller 2 and the pressing roller 4. The first guiding roller 11 and the second guiding roller 12 are respectively abutted against the abrasive tool to tension the abrasive tool, and the abrasive tool is rewound after passing through the second guiding roller 12, so that the abrasive tool can move on the frame 1. While the abrasive tool is moving, start the first driving member and the second driving member. When the water-absorbing roller 2 rotates under the drive of the first driving member, the water-absorbing layer 21 continuously sucks clear water from the water tank 5. At the same time, the water-dipping roller 3 rotates under the drive of the second driving member and squeezes the water-absorbing layer 21 to make the water in the water-absorbing layer 21 adhere to the flexible layer 31. When the abrasive tool passes through the gap between the water-dipping roller 3 and the pressing roller 4, the pressing roller 4 presses the surface of the abrasive tool against the flexible layer 31 to smear the water on the surface of the flexible layer 31 onto the abrasive tool, thereby humidifying the abrasive tool. The abrasive tool humidifying device provided in this embodiment enables the clear water absorbed by the water-absorbing layer 21 to evenly adhere to the surface of the flexible layer 31 by the rotation of the water-absorbing roller 2 and the water-dipping roller 3, so as to evenly apply the clear water to the abrasive tool, while avoiding excessive absorption of clear water by some surfaces of the abrasive tool, improving the uniformity of the humidifying treatment of the abrasive tool and preventing water stains from appearing on the surface of the abrasive tool, which is beneficial to improving the product quality.

[0025] As Figure 2 shown, the water-absorbing layer 21 includes a sponge layer, and a plurality of grooves are arranged at intervals along the circumferential direction of the water-absorbing roller 2 on the sponge layer. The water-absorbing layer 21 includes a sponge layer, which is used to suck the clear water in the water tank 5 and transport it to a position close to the water-dipping roller 3, and a plurality of grooves are arranged at intervals on the sponge layer to ensure that the sponge layer can deform when being squeezed by the water-dipping roller 3 and squeeze out the clear water in the sponge layer, so as to evenly smear the sponge layer on the flexible layer 31.

[0026] In this embodiment, the flexible layer 31 includes a rubber layer, the rubber layer abuts against the sponge layer, and the position where the sponge layer contacts the rubber layer is compressed. The flexible layer 31 includes a soft rubber layer, so that the abrasive can be closely fitted with the rubber layer under the action of the pressing roller 4, and the hardness of the rubber layer is greater than that of the sponge layer, ensuring that the sponge layer is compressed during the mutual extrusion of the rubber layer and the sponge layer, so that the clear water in the sponge layer is squeezed out and adheres to the rubber layer, and then the clear water is evenly smeared on the abrasive tool by the rotation of the water-dipping roller 3, improving the reliability of the abrasive tool humidifying device.

[0027] Please combine Figure 1 and Figure 3The frame 1 is also provided with an adjustment seat 6. The pressure roller 4 is arranged on the adjustment seat 6 in a manner that allows it to be raised and lowered. The adjustment seat 6 is provided with a drive assembly that is in transmission connection with the pressure roller 4. The drive assembly drives the pressure roller 4 to move vertically toward or away from the dampening roller 3. The drive assembly drives the pressure roller 4 to rise and fall in the vertical direction to adjust the position of the pressure roller 4 and press the abrasive tool against the surface of the dampening roller 3, thereby preventing a gap from forming between the abrasive tool and the dampening roller 3, which would cause uneven application of clean water on the abrasive tool. The width of the gap between the pressure roller 4 and the dampening roller 3 can be adjusted by raising and lowering the pressure roller 4, thereby meeting the humidification treatment requirements for abrasive tools of various thicknesses, making the abrasive tool humidification device more versatile.

[0028] In detail, two adjustment seats 6 are provided on the frame 1 at intervals, and the two adjustment seats 6 are respectively arranged near the opposite ends of the pressure roller 4. Slide blocks 41 are respectively provided at the opposite ends of the pressure roller 4, and the adjustment seats 6 are respectively provided with chute 61 that correspond one-to-one with the slide blocks 41. Two adjustment seats 6 are provided on the frame 1 for mounting the pressure roller 4 to improve the stability of the pressure roller 4 on the frame 1, and the slide blocks 41 are respectively provided at the two ends of the pressure roller 4 to correspond one-to-one with the chute 61 on the adjustment seat 6. The position of the pressure roller 4 can be adjusted by sliding the slide blocks 41 in the chute 61, ensuring that the pressure roller 4 remains level during the adjustment process, thereby preventing the pressure roller 4 from tilting and causing a gap between the mold and the wet roller 3.

[0029] like Figure 3 As shown, a vertical guide rod 62 is provided in the chute 61, and a guide hole is provided on the slider 41 to cooperate with the guide rod 62. The guide rod 62 is used to retain the slider 41 in the chute 61, preventing the slider 41 from detaching from the adjustment seat 6 when the pressure roller 4 moves, thereby improving the structural stability of the mold humidification device.

[0030] Please refer to Figure 3, the driving component includes a pressing plate 63 and a spring 64 respectively arranged in the sliding groove 61. The pressing plate 63 and the spring 64 are respectively in contact with the opposite two surfaces of the slider 41 in the vertical direction, and the pressing plate 63 can move up and down in the vertical direction in the sliding groove 61. The driving component includes a pressing plate 63 and a spring 64 respectively in contact with the upper and lower surfaces of the slider 41. The pressing plate 63 cooperates with the sliding groove 61 and can move up and down in the vertical direction in the sliding groove 61. The spring 64 is sleeved on the guide rod 62 to keep the spring 64 in contact with the slider 41. By pressing down the pressing plate 63, the slider 41 can be pushed to move downward and the pressing roller 4 can be driven to move downward in the vertical direction. At this time, the spring 64 is further compressed. When the pressing plate 63 rises, the spring 64 extends and drives the slider 41 to rise by the elastic force provided by the spring 64. At this time, the pressing roller 4 moves upward in the vertical direction under the push of the spring 64, so as to realize the adjustment of the height of the pressing roller 4.

[0031] Specifically, the driving component further includes an adjusting screw 65 rotatably arranged on the adjusting seat 6. The axial direction of the adjusting screw 65 is the vertical direction, and the pressing plate 63 is provided with a threaded hole matching with the adjusting screw 65. By rotating the adjusting screw 65, the pressing plate 63 can be driven to move along the axial direction of the adjusting screw 65, so as to drive the pressing plate 63 to press down or rise in the vertical direction to adjust the position of the pressing roller 4. At the same time, the position of the pressing plate 63 can be locked by the cooperation of the threaded hole and the adjusting screw 65, so as to keep the pressing roller 4 in the corresponding position and prevent the pressing roller 4 from moving unexpectedly during the process of humidifying the grinding tool by the grinding tool humidifying device.

[0032] As Figure 2 shown, a spraying component is arranged on the water tank 5. The spraying component includes a water pump and a water spraying pipe 51 connected in communication. The water spraying pipe 51 extends into the water tank 5, and a plurality of spray heads 52 are arranged on the water spraying pipe 51 at intervals along the axial direction of the water absorbing roller 2. The spray heads 52 respectively face the side of the water absorbing roller 2 away from the water dipping roller 3. Pumping clear water into the water spraying pipe 51 by the water pump can make the spray heads 52 spray clear water on the water absorbing roller 2, ensuring that the part of the water absorbing layer 21 extending into the water tank 5 can absorb enough clear water. And the spray heads 52 face the side of the water absorbing roller 2 away from the water dipping roller 3, avoiding the water sprayed from the spray heads 52 being sprayed on the water dipping roller 3 and causing uneven attachment of clear water on the surface of the water dipping roller 3, which affects the humidifying effect.

[0033] Specifically, a third guide roller 13 and a water scraping component 7 are sequentially arranged between the pressing roller 4 and the second guide roller 12. The water scraping component 7 includes a water scraping frame 71 and a water scraping plate 72 arranged on the water scraping frame 71. The water scraping plate 72 is located directly above the water tank 5 and extends towards the direction close to the third guide roller 13. A third guide roller 13 and a water scraping component 7 are also arranged on the machine frame 1. After passing through the gap between the water-dipping roller 3 and the pressing roller 4, the grinding tool abuts against the third guide roller 13 and then abuts against the second guide roller 12. The water scraping component 7 includes a water scraping frame 71 fixedly connected to the machine frame 1 and the water scraping plate 72 arranged on the water scraping frame 71. The water scraping plate 72 contacts the surface of the grinding tool after humidification and scrapes off the excess clear water on the surface of the grinding tool, avoiding water accumulation on the surface of the grinding tool from affecting the product quality, and the scraped clear water falls into the water tank 5 below to reduce water resource waste.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
