Description

Technical Field

[0001] The utility model specifically relates to a long side precision milling device for a foamed board with high stability. Background Art

[0002] The main component of the foam board is polyethylene terephthalate, commonly known as polyester resin. The foam core material is a type of closed-cell thermoplastic structural foam with certain shear and compression strength. Therefore, it is often used as the core material of sandwich structure materials and is widely used in construction, road transportation, rail transportation, aviation, communication, wind power and other fields.

[0003] After the foam board is processed, it is usually a rectangular board with short sides and long sides. The four side walls need to be fine-milled to remove burrs, so as to facilitate the later installation and use of the foam board. Since the size of the foam board is fixed when in use, the short side fine milling and long side fine milling of the foam board are carried out using devices with similar structures.

[0004] However, when the existing foam board fine milling device fine mills the long side of the foam board, the board is easily displaced and deviated due to the impact force generated during processing, which is not conducive to the processing of the foam board;

[0005] Moreover, the traditional foam board precision milling device has only one set of cutting tools on the outside of each base frame. Since the long sides of the foam boards are usually uneven and have redundant parts, the foam boards can only be milled once after entering and exiting, resulting in insufficient processing accuracy of the long sides of the foam boards, affecting subsequent use.

[0006] Therefore, it is necessary to invent a foam board long side fine milling device with higher stability to solve the above problems. Utility Model Content

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] The utility model provides Figure 1-7A highly stable long-side precision milling device for a foamed board is shown, comprising two parallel-arranged bases 1, a base frame 2 laterally distributed on the front and rear sides of the base 1, an adsorption mechanism 3 arranged on the top of the base frame 2, a precision milling mechanism 4 arranged on the outside of a conveying mechanism 6, and an adjustment mechanism 5 installed between the base 1 and the base frame 2;

[0047] The adsorption mechanism 3 includes an adsorption platform 31 longitudinally mounted on each of the base frames 2 and used to carry the foaming board. The top of the adsorption platform 31 is recessed downward with a groove 32, and a plurality of partitions 33 are longitudinally spaced in the groove 32. A plurality of exhaust pipes 34 are also mounted on the side wall of the adsorption platform 31.

[0048] The fine milling mechanism 4 includes two grinding wheels 41 installed on the outside of each base frame 2, a protective cover 42 sleeved on the outside of the grinding wheel 41, and a fine milling motor 43 arranged under the grinding wheel 41 for driving the grinding wheel 41 to rotate;

[0049] The adjusting mechanism 5 comprises a guide rail 51 mounted on the top of the two bases 1, a slider 52 sleeved on the outside of the guide rail 51 and capable of sliding forward and backward along the top of the base 1, and the bottoms of the left and right ends of the two base frames 2 are respectively connected to the sliders 52 below them; it also comprises a transmission rod 53 longitudinally running through the left and right ends of the two base frames 2, the middle sections of the two transmission rods 53 are both equipped with a steering gear 54, the corresponding sides of the two steering gears 54 are both equipped with a coupling 55, and a connecting rod 56 is installed between the two couplings 55; wherein, an adjusting motor 57 is also installed on the top of the base 1 on the right side, and the output end of the adjusting motor 57 is connected to the transmission rod 53 on the right side, and the adjusting mechanism 5 can adjust the spacing between the two base frames 2 for the four grinding wheels 41 to cut;

[0050] Among them, the two grinding wheels 41 located on the outside of each base frame 2 are staggered 2-3 cm front and back, and the foaming board on the adsorption table 31 can be finely milled twice. The staggered grinding wheels 41 on the left and right sides can disperse the cutting width of the grinding wheel 41, reduce the wear of the grinding wheel 41, and increase the service life of the grinding wheel 41.

[0051] like Figure 6-7As shown, in one embodiment, the grinding wheel 41 located on the right side of each base frame 2 is composed of a first wheel body 44 and a second wheel body 45 connected to the first wheel body 44, and is used to mill steps on the side wall of the foam board. The outer diameter of the first wheel body 44 is smaller than the outer diameter of the second wheel body 45, and the grinding surfaces of the first wheel body 44 and the second wheel body 45 are in the shape of threaded teeth with opposite rotation directions. The grinding surface of the grinding wheel 41 located on the left side of each base frame 2 is the same as the first wheel body 44, so that the grinding wheel 41 on the right side can perform initial fine milling of the foam board through the first wheel body 44, and can also mill steps on the long side of the foam board through the second wheel body 45, so that the grinding and grooving of the foam board can be carried out on the device, thereby improving the processing efficiency of the foam board, and the sizes of the grinding wheels 41 on the left and right sides can be replaced according to the actual grinding and grooving depths.

[0052] In one embodiment, the transmission rod 53 and the base frame 2 are configured to be threadedly connected, and the threads on the outer sides of the two transmission rods 53 are configured to be bidirectional threads, so that when the transmission rod 53 rotates, the two base frames 2 can move away from or approach each other.

[0053] In one embodiment, the long side fine milling device of the foam board with higher stability also includes a conveying mechanism 6 installed on the outside of the adsorption mechanism 3, which is used to horizontally convey the foam board on the adsorption table 31, and the conveying mechanism 6 includes a conveyor belt 61 longitudinally surrounding the outside of each adsorption table 31, and a conveying wheel 62 arranged inside the two ends of the conveyor belt 61 and connected to the base frame 2, wherein the conveying wheel 62 located on the right side of the base frame 2 has a rotating shaft 63 passing through it, and a driving motor 64 is installed on the top of the rear side of the base frame 2, and the output end of the driving motor 64 is connected to the rotating shaft 63, so as to ensure that the movement speed of the foam board is always the same, and will not be fast or slow, and the movement speed is uniform.

[0054] In one embodiment, a plurality of convex strips 65 are installed on the outer side of the rotating shaft 63, and each of the transmission wheels 62 is sleeved on the outer side of the rotating shaft 63 through the convex strips 65, so that when the two base frames 2 move away from each other due to the rotation of the transmission rod 53, the transmission wheel 62 can move along the rotating shaft 63, and due to the presence of the convex strips 65, the rotating shaft 63 can always drive the transmission wheel 62 to rotate. A spline protective sleeve 66 is installed on the end of the rotating shaft 63 away from the driving motor 64 to ensure the stability of the rotating shaft 63, stabilize its performance, and improve its service life.

[0055] The specific implementation method is as follows: when the utility model is in use, the exhaust pipe 34 is connected to the external vacuum equipment, and the grinding wheel 41 on the right side is arranged farther away from the adsorption platform 31 than the grinding wheel 41 on the left side. Specifically:

[0056] The staff first places the foam board that needs to be finely milled on the long side above the adsorption table 31, starts the driving motor 64, drives the rotating shaft 63 to rotate, and then rotates the conveying wheel 62, and further makes the conveyor belt 61 run around the adsorption table 31, and transports the foam board from right to left. The moving speed of the foam board depends on the transmission speed of the conveyor belt 61, thereby ensuring that the moving speed of the foam board is always the same, and will not be fast or slow, and the moving speed is uniform;

[0057] When the foam board is conveyed on the conveyor belt 61, the external vacuum equipment will absorb the air in the adsorption platform 31 through the exhaust pipe 34, so that negative pressure is formed in the groove 32, so that the adsorption platform 31 can basically adsorb the foam board, preventing the foam board from shifting or running off due to the impact force when being ground by the grinding wheel 41, thereby improving the precision milling quality of the long side of the foam board and reducing the generation of bad parts;

[0058] The grinding wheels 41 on both sides can rotate around their own axes under the control of the fine milling motors 43. When the long side of the foam board passes through the grinding wheels 41, the grinding wheels 41 can grind the long side of the foam board to remove the burrs on the long side of the foam board, and achieve fine milling of the long side of the foam board, which is convenient for the later installation and use of the foam board. Specifically:

[0059] The long sides of the foam board first contact with the two grinding wheels 41 on the right side. The two grinding wheels 41 rotate to mill off the redundant part of the foam board, which is generally 2-3 cm wide, so that the long side of the foam board becomes relatively smooth and flat. As the foam board continues to be transported to the left, the long side that has been processed once will contact the grinding wheel 41 on the left again. At this time, since the long side of the foam board is relatively flat, the grinding wheel 41 on the left can use the preliminary processing of the grinding wheel 41 on the right as a basis to more accurately trim and improve the long side of the foam board, thereby improving the smoothness and precision of the long side of the foam board. That is, the secondary fine milling process can further improve the quality of the foam board and approach the ideal state.

[0060] When the foaming plate is placed in front of the adsorption table 31, the staff can start the adjustment motor 57 to control its output end to rotate forward or reverse, so that the transmission rod 53 on the right side rotates, and then the two base frames 2 are moved closer to or away from each other along the guide rail 51. At the same time, the transmission rod 53 on the right side can be transmitted through the steering gear 54, the coupling 55, and the connecting rod 56, so that the transmission rod 53 on the left side rotates in the same direction, so that the left and right ends of the base frame 2 move synchronously, thereby ensuring the stability of the base frame 2 sliding on the base 1. In this process, the spacing between the front and rear corresponding grinding wheels 41 can be fine-tuned by the translation of the base frame 2, so as to facilitate the cutting of the grinding wheel 41.

[0061] This embodiment specifically solves the problem that when the current foam board precision milling device in the prior art precision mills the long side of the foam board, the board is easily displaced and deviated due to the impact force generated during processing, which is not conducive to the processing of the foam board; and the traditional foam board precision milling device has only one set of cutting tools on the outer side of each base frame 2, and because the long side of the foam board is usually uneven and has redundant parts, the foam board can only be milled once after entering and exiting, resulting in insufficient processing accuracy of the long side of the foam board, affecting subsequent use.

[0062] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
