Description

Technical Field

[0001] The utility model relates to the technical field of PVB board processing, in particular to a surface grinding device for PVB board processing. Background Art

[0002] PVB board is a polymer material, mainly composed of polyvinyl butyral resin (PVB resin), which is formed by plasticizing and extruding with plasticizer 3GO (triethylene glycol diisooctanoate). PVB is a transparent thermoplastic resin with good adhesion, toughness and optical transparency, so it is very popular in many industrial applications.

[0003] When grinding PVB board, especially when facing long templates, some difficulties will be encountered. Due to the unique material properties of PVB, PVB, this material shows relatively soft properties under certain conditions. Especially when the ambient temperature is high or the ambient humidity is high, its softness will be more obvious. This softness makes the long strip PVB template very easy to bend or even sag without sufficient support. Therefore, when pushing the long PVB template into the grinder, if the PVB template is not straightened, it is easy to cause the PVB template to break.

[0004] Therefore, it is necessary to design a surface grinding equipment for PVB board processing. Utility Model Content

[0005] In order to overcome the disadvantage that it is inconvenient to straighten the PVB template, the utility model provides a surface grinding device for processing the PVB board.

[0006] A surface grinding device for processing PVB boards comprises a shell and a grinding wheel, wherein a cavity is arranged in the upper inner part of the shell, and a grinding wheel is symmetrically rotatably mounted in the upper inner part of the shell, and further comprises a scissor frame, a movable frame and a transmission wheel, wherein slide grooves are symmetrically arranged on the left middle part of the shell, and scissor frames are slidably mounted in the slide grooves on both sides, and the scissor frames are designed as a whole with a scissor-type structure, and a group of movable frames is hingedly arranged between two scissor frames, and a group of movable frames has four members, and transmission wheels are arranged on the tops of the four movable frames through shaft rotation.

[0007] Optionally, a mounting frame and a locking rope are also included. The mounting frame is provided on the right front side of the shell, and the locking rope is wound around the mounting frame through a take-up wheel.

[0008] Optionally, a cleaning wheel is further included, which is symmetrically rotatably arranged on the right side of the shell.

[0009] Optionally, the bottom of the four mobile frames is equipped with wheels.

[0010] Optionally, a gap is left between the grinding wheels for the PVB board to pass through.

[0011] Optionally, the tail end of the locking rope is designed to be hook-shaped, and a hook opening that cooperates with the hook portion of the locking rope is provided on the left front side of the shell.

[0012] The beneficial effects and significant improvements of the utility model are:

[0013] The utility model triggers the extension mechanism of the scissor frame by pulling the first mobile frame outward, thereby driving the remaining mobile frames to move outward in sequence. This design significantly increases the area of ​​the feed port and provides sufficient supporting space for longer PVB boards. In this way, when guiding the PVB boards into the grinding equipment, the staff does not need to provide additional support, which reduces the labor intensity and makes the operation process easier and more convenient.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0021] Example: A surface grinding device for PVB board processing, please see Figures 1 to 5, including a shell 1, a grinding wheel 2, a scissor frame 3, a moving frame 4, a transmission wheel 5, a mounting frame 7, a locking rope 8 and a cleaning wheel 9. The upper inner part of the shell 1 is provided with a cavity for grinding, and the lower inner part of the shell 1 is provided with a cavity for collecting grinding plate chips. The grinding wheel 2 is symmetrically installed in the grinding cavity of the shell 1, and the grinding wheel 2 can be connected to the driving component to realize the rotation of the grinding wheel 2. A gap is left between the grinding wheels 2 for passing the PVB board. A slide groove 6 is symmetrically opened in the middle left part of the shell 1 in the front and back manner. The scissor frames 3 are slidably installed in the slide grooves 6 on both sides. The scissor frame 3 adopts a scissor-type structure design as a whole, so that the scissor frame 3 can be telescopic. Action, a group of mobile frames 4 are hingedly connected between the two scissor frames 3, and the number of a group of mobile frames 4 is four. The bottom of the four mobile frames 4 is equipped with wheels for easy movement. The tops of the four mobile frames 4 are connected to the transmission wheels 5 through shaft rotation, which can provide support and auxiliary transportation for the PVB panels. A mounting frame 7 is fixedly connected to the right front side of the shell 1 by bolts, and a locking rope 8 is wound around the mounting frame 7 through a take-up wheel. The tail end of the locking rope 8 is designed in a hook shape, and a hook mouth that cooperates with the hook part of the locking rope 8 is provided on the left front side of the shell 1. A cleaning wheel 9 is symmetrically rotated on the right side of the shell 1, and nylon bristles are provided on the surface of the cleaning wheel 9, which can effectively clean the board chips.

[0022] When the surface of the PVB board needs to be polished, first pull the mobile frame 4, and the wheels installed at the bottom can save more effort when moving. During the pulling process, the scissor frame 3 scissor-type structure design can be extended, thereby driving the remaining mobile frames 4 to move outward together, thereby expanding the feed port area of ​​the polishing equipment, which is convenient for the placement and transportation of the PVB board. Then, the staff connects the power supply of the polishing equipment and prepares to start work. The PVB board to be polished is placed on the conveying wheel 5, which can firmly support the PVB board so that it can smoothly enter the polishing cavity inside the shell 1. When the operator slowly pushes the PVB board, the grinding wheel 2 is driven to rotate by the driving component of the polishing equipment, and the relative rotation of the two grinding wheels 2 finely polishes the surface of the PVB board. The board chips generated during the polishing process will be collected by the cavity below the shell 1 to keep the working area clean. After the polishing is completed, the PVB board is sent out from the discharge port on the right side of the shell 1. During this process, the PVB board will pass through the cleaning wheel 9, and the nylon brush on the surface of the cleaning wheel 9 will contact the PVB board, effectively removing the board chips remaining on the surface, ensuring that the polished PVB board is clean and dust-free. Finally, the staff will take out the cleaned PVB board and prepare for the polishing of the next board.

[0023] When a series of grinding work is completed and the grinding equipment is no longer needed, the mobile frame 4 can be pushed back to its original position, and the scissor frame 3 will shrink and reset accordingly, so that the feed port area is reduced and space is saved. In order to prevent the mobile frame 4 from moving at will when not in use, a locking rope 8 can be used. One end of the locking rope 8 is stretched and wrapped around the mobile frame 4, and then the hook part of the locking rope 8 is hooked at the hook mouth of the housing 1 to fix the mobile frame 4 and ensure that it is stable and motionless in the non-working state.
