Description

Technical Field

[0001] This utility model belongs to the field of grinding disc technology, specifically relating to a resin grinding disc velvet bonding and pressing machine. Background Technology

[0002] Resin grinding discs are cheaper than metal discs because the resin provides a cushioning and fixing effect, making them less likely to scratch the stone during grinding and preventing irreparable scratches. They also have lower requirements for the grinding discs that follow. During the production of resin grinding discs, a piece of velvet needs to be attached to the disc to facilitate disassembly and assembly as a bonding surface during use.

[0003] However, the existing public document CN217434078U describes a velvet pasting device for producing resin grinding discs. It uses a rotating roller to press the velvet and resin grinding disc together multiple times during rotation. The pressing is performed during the transmission process. This can easily cause the resin grinding disc to shift during the rotation of the roller, resulting in inaccurate pressing. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a resin abrasive cloth bonding and pressing machine that can press precisely and extend the pressing time to make the adhesion more firm.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a resin abrasive cloth bonding and pressing machine, including a frame, two pressing components and two transmission components. The two pressing components are mounted on the frame, and the two transmission components are respectively mounted on corresponding sides of the frame, with the output end of the transmission components facing the pressing components. Each transmission component includes a support frame, two upper transmission channels, two lower transmission channels, two receiving movable plates and two support lifters. The two upper transmission channels and the two lower transmission channels are all mounted on corresponding sides of the support frame. The upper transmission channels are positioned above the lower transmission channels. The two receiving movable plates are respectively movably mounted on the two upper transmission channels and the two lower transmission channels. The two support lifters are respectively positioned below the two receiving movable plates.

[0006] The receiving moving plate includes a receiving plate and four driving wheels. The four driving wheels are respectively arranged at the four corners of the receiving plate and roll within the upper or lower transmission channel. The input and output of the two upper transmission channels and the two lower transmission channels are provided with transition grooves for the rotating wheels to pass through.

[0007] The lifting end of the support lift is provided with a support block corresponding to the position of the rotating wheel, and the support block fits into the transition groove.

[0008] The support lifter includes a hydraulic actuator and a support plate. The hydraulic actuator is installed inside the support frame and located below the lower transmission channel. The support plate is installed on the output end of the hydraulic actuator.

[0009] The pressing assembly includes a pressing head and two synchronizing cylinders. Both synchronizing cylinders are mounted on the top of the frame, with their output ends facing the upper transmission channel. The pressing head is mounted on the output end of the synchronizing cylinders.

[0010] The pressing head includes a fixed frame and a pressure plate. The fixed frame is installed on the output end of the synchronizing cylinder, and the pressure plate is welded to the bottom of the fixed frame and is located between the two upper transmission channels.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model of a resin abrasive sheet bonding and pressing machine uses a pressing component that remains stationary for a long time to achieve a stronger bond and more precise pressing. It also features a transmission component that enables automatic return of the plate to accelerate production efficiency. Attached Figure Description

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-3As shown, this embodiment provides a resin abrasive sheet bonding and pressing machine, including a frame 1, two pressing components 2 and two transmission components 3. The two pressing components 2 are mounted on the frame 1, and the two transmission components 3 are respectively mounted on corresponding sides of the frame 1, with the output end of the transmission components 3 facing the pressing components 2. The transmission components 3 include a support frame 4, two upper transmission channels 5, two lower transmission channels 6, two receiving movable plates 7 and two support lifters 8. The two upper transmission channels 5 and the two lower transmission channels 6 are both mounted on corresponding sides of the support frame 4. The input and output of the upper transmission channels 5 are opposite to those of the lower transmission channels 6. The upper transmission channels 5 are located above the lower transmission channels 6. The two receiving movable plates 7 are respectively movably mounted on the two upper transmission channels 5 and the two lower transmission channels 6. The two support lifters 8 are respectively located below the two receiving movable plates 7, and the two support lifters 8 are respectively located at the input and output of the two upper transmission channels 5. During the pressing process, the resin grinding discs are placed on the receiving moving plate 7, which then moves along the two upper transmission channels 5 to be positioned below the pressing assembly 2 for pressing. Simultaneously, the lower support lifter 8 provides output support, while the other receiving moving plate 7 is pushed upwards by the support lifter 8, placing the receiving moving plate 7 in the lower transmission channel 6 onto the upper transmission channel 5. While waiting for the pressing process, the resin grinding discs to be pressed can be placed on this receiving moving plate 7. After the previous batch of resin grinding discs has been pressed, the lower support lifter 8 drives the receiving moving plate 7 downwards. The plate is lowered and placed on the lower transmission channel 6. Then, the receiving moving plate 7 moves along the lower transmission channel 6 to the initial position. At the same time, the support lift 8 at the output of the upper transmission channel 5 rises and resets. The support lift 8 at the output of the lower transmission channel 6 pushes the receiving moving plate 7, which has been pressed, upward and places it at the input of the upper transmission channel 5. Then, the resin grinding plate is removed and a new resin grinding plate is placed. The rising operation is repeated to achieve resin grinding plate pressing. The long-term pressing by fixing the pressing component 2 makes the adhesion stronger and the pressing more accurate. The transmission component 3 is set to realize automatic return plate transmission to speed up production efficiency.

[0019] Specifically, the receiving movable plate 7 includes a receiving plate and four drive wheels. Synchronizers (not shown in the figure) are installed on the four drive wheels, which are respectively located at the four corners of the receiving plate and roll within the upper transmission channel 5 or the lower transmission channel 6. Transition grooves 9 for the rotating wheels are provided at the input and output points of both upper transmission channels 5 and both lower transmission channels 6. A support block 10 is provided at the lifting end of the support lifter 8 corresponding to the position of the rotating wheel, and the support block 10 fits into the transition groove 9. The four drive wheels drive the receiving movable plate 7 to move on the upper transmission channel 5 or the lower transmission channel 6, and the transition grooves 9, in conjunction with the support lifter 8, enable the receiving movable plate 7 to switch between the upper transmission channel 5 and the lower transmission channel 6.

[0020] Furthermore, the support lift 8 includes a hydraulic actuator and a support plate. The hydraulic actuator is installed inside the support frame 4 and located below the lower transmission channel 6. The support plate is installed on the output end of the hydraulic actuator. The hydraulic actuator pushes the support plate up and down, thereby driving the receiving movable plate 7 to move up and down.

[0021] Furthermore, the pressing assembly 2 includes a pressing head 12 and two synchronous cylinders 11. Both synchronous cylinders 11 are mounted on the top of the frame 1, with their output ends facing the upper transmission channel 5. The pressing head 12 is mounted on the output ends of the synchronous cylinders 11. Specifically, the pressing head 12 includes a fixed frame and a pressure plate. The fixed frame is mounted on the output ends of the synchronous cylinders 11, and the pressure plate is welded to the bottom of the fixed frame, positioned between the two upper transmission channels 5. The pressing head 12 is synchronously driven downwards by the two synchronous cylinders 11 to perform the pressing.
