Description

Technical Field

[0001] The present invention relates to the field of foam plastic board processing, and particularly to an edge grinding device for foam plastic boards. Background Art

[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. They have characteristics such as light weight, heat insulation, sound absorption, shock absorption, etc., and their dielectric properties are superior to those of the matrix resin. They are widely used, and almost any plastic can be made into foam plastics. Foam plastic boards need to be edge-ground during processing to enhance their practicality.

[0003] Specifically, for an edge grinding machine for foam plastic boards with the patent number CN112605783B, the device has the following defects when grinding the board. For example, the power sources for driving the grinding mechanism and the upper and lower two groups of moving mechanisms are separately set, so that the kinetic energy generated by the power source is not fully utilized. At the same time, it can only grind a fixed point at one end of the board. Subsequently, it is necessary to move or rotate the board to grind different regions at one end or different positions at both ends of the board, which leads to an increase in the operation difficulty. Summary of the Invention

[0004] The purpose of the present invention is to provide an edge grinding device for foam plastic boards.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] An edge grinding device for foam plastic boards includes a workbench. On both sides of the top of the workbench, U-shaped plates are provided. A driving mechanism for driving the two U-shaped plates to move is provided on the workbench. A grinding mechanism is provided on the U-shaped plates. A support seat is further provided on the workbench between the two U-shaped plates. A strip-shaped seat is provided on the support seat. A transmission mechanism for driving the strip-shaped seat to move back and forth is provided on the grinding mechanism;

[0007] The driving mechanism includes a chute I provided on the top of the workbench. A sliding seat located in the chute I is provided at the bottom of the U-shaped plate. A forward and reverse screw driven by a motor I is provided on the sliding seat;

[0008] The grinding mechanism includes a motor II provided on the top of the U-shaped plate. A grinding seat with an hourglass shape is provided on the output shaft of the motor II;

[0009] The transmission mechanism includes strip-shaped grooves provided on both side walls of the strip-shaped seat. An active cavity located between the two groups of strip-shaped grooves is also provided in the strip-shaped seat. A rack is provided in the strip-shaped groove. A sliding rod extending into the active cavity is provided on the back surface of the rack. A spring is sleeved on the sliding rod in the strip-shaped groove. A gear meshing with the corresponding rack is fixed to the inner bottom of the U-shaped plate through a rotating shaft. A toothed ring meshing with the corresponding gear is provided on the output shaft of the motor II.

[0010] Preferably, the number of the first sliding grooves is two groups. The two groups of the first sliding grooves are located on both sides of the support seat and are vertically arranged with respect thereto. The sliding seat is located in the corresponding first sliding groove. A threaded hole screwed with the forward and reverse lead screw is provided on the sliding seat.

[0011] Preferably, bearings for fixing the bottom end of the output shaft of the motor II and the bottom end of the rotating shaft are provided on the inner bottom wall of the U-shaped plate.

[0012] Preferably, a second sliding groove is arranged along the length direction of the top of the support seat. The cross-section of the second sliding groove is in an inverted T-shaped structure. A slider adapted thereto is provided at the bottom of one end of the strip-shaped seat and is located in the second sliding groove.

[0013] Preferably, bumps are provided at the ends of the sliding rods in the active cavity. The corresponding bumps on both sides are arranged staggeredly front and back. Through holes for the sliding rods to pass through are provided on the side walls of the active cavity.

[0014] Preferably, a long strip-shaped cover body for supporting the plate is buckled on the top of the strip-shaped seat. The side wall of the cover body is fixed to the strip-shaped seat through bolts.

[0015] The beneficial effects of the present invention are as follows: the present invention drives the displacement of the profile plate and the grinding mechanism through the driving mechanism, thereby reducing the spacing between the two groups of grinding seats to clamp and limit the two sides of one end of the plate, and at the same time, the moving profile plate drives the gear to engage with the corresponding rack through the rotating shaft. When the width of the plate is small, the gear squeezes the rack to slide into the strip groove and drives the slide rod to slide in the through hole, and squeezes the spring to contract so that the rack retracts into the strip groove, so that the two groups of grinding seats can clamp and grind plates of different widths, and the transmission mechanism can be smoothly connected to the strip seat, thereby fixing and grinding plates of different widths, and at the same time, the motor II drives the grinding seat to rotate When grinding the edges of the plates at both ends, the output shaft of motor II will also drive the rack forward through the gear ring and the gear. At this time, the rack pushes the strip seat, the cover body and the plate above it forward by hanging the side wall of the through hole through the sliding rod, so that the grinding seat can grind the entire outer wall of both ends of the plate. The motor II in the grinding mechanism of the present invention can not only grind the two ends of the plate through the grinding seat, but the power generated can also drive the plate to move through the transmission mechanism, the strip seat and the cover body, so as to cooperate with the grinding seat to perform full-coverage grinding of the entire outer wall of both ends of the plate, thereby improving work efficiency and processing plates of different widths.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] A foam plastic plate edge grinding device, including a workbench 1, on both sides of the top of the workbench 1, there are C-shaped plates 2. Among them, on the workbench 1, there is a driving mechanism 3 for driving the two groups of C-shaped plates 2 to move. On the C-shaped plates 2, there is a grinding mechanism 4. Among them, on the workbench 1 between the two groups of C-shaped plates 2, there is also a support seat 5. On the support seat 5, there is a strip-shaped seat 6. On the grinding mechanism 4, there is a transmission mechanism 7 for driving the strip-shaped seat 6 to move back and forth.

[0023] The driving mechanism 3 includes a chute I 31 arranged on the top of the workbench 1. Among them, at the bottom of the C-shaped plate 2, there is a sliding seat 32 located in the chute I 31. On the sliding seat 32, there is a positive and reverse lead screw 33 driven by a motor I 34. The number of the chutes I 31 is two groups. Among them, the two groups of chutes I 31 are located on both sides of the support seat 5 and are perpendicular to it. The sliding seat 32 is located in the corresponding chute I 31. On the sliding seat 32, there is a screw hole screwed with the positive and reverse lead screw 33.

[0024] The grinding mechanism 4 includes a motor II 41 arranged on the top of the C-shaped plate 2. On the output shaft of the motor II 41, there is a grinding seat 42 in the shape of an hourglass structure.

[0025] The transmission mechanism 7 includes strip-shaped grooves 71 arranged on both side walls of the strip-shaped seat 6. In the strip-shaped seat 6, there is also an activity cavity 72 located between the two groups of strip-shaped grooves 71. In the strip-shaped grooves 71, there are racks 73. On the back of the racks 73, there are sliding rods 74 extending into the activity cavity 72. On the sliding rods 74 in the strip-shaped grooves 71, there are springs 75 sleeved. The inner bottom of the C-shaped plate 2 is fixed with gears 77 meshing with the corresponding racks 73 through a rotating shaft 76. On the output shaft of the motor II 41, there is a toothed ring 78 meshing with the corresponding gear 77.

[0026] On the top of the support seat 5, along its length direction, there is a chute II 8. The cross-section of the chute II 8 is in an inverted T-shaped structure. One end bottom of the strip-shaped seat 6 is provided with a slider 9 located in the chute II 8 and adapted to it. By the way of hanging the slider 9 by the chute II 8, the separation of the strip-shaped seat 6 from the support seat 5 is prevented. And when the strip-shaped seat 6 moves on the support seat 5, the slider 9 at one end bottom of it will slide in the chute II 8. When the slider 9 contacts the other end of the chute II 8, the movement of the strip-shaped seat 6 will be restricted, so as to achieve the purpose of restricting the movement amplitude of the strip-shaped seat 6.

[0027] In this embodiment, on the inner bottom wall of the C-shaped plate 2, there are bearings for fixing the bottom end of the output shaft of the motor II 41 and the bottom end of the rotating shaft 76.

[0028] Such as Figure 3 、 4As shown, the ends of the slide bars 74 in the movable cavity 72 are provided with protrusions 10, wherein the corresponding protrusions 10 on both sides are staggered front and back, and the side walls of the movable cavity 72 are provided with through holes for the slide bars 74 to pass through. The side walls of the movable cavity 72 abut against the protrusions 10 to prevent the slide bars 74 from sliding out of the through holes, thereby causing the slide bars 74 and the rack 73 to slide out of the strip groove 71.

[0029] In this embodiment, a long strip cover 11 for supporting the plate is buckled on the top of the strip seat 6, and the side wall of the cover 11 is fixed to the strip seat 6 by bolts 12. By adjusting the height of the cover 11, the height of the plate located above it can be adjusted, so that when both ends of the plate supported by it are located in the opening of the moved grinding seat 42, the upper and lower side walls of the end of the plate are respectively against the upper and lower side walls of the beveled ends in the opening of the grinding seat 42.

[0030] The method of using the present invention is as follows: a plate is placed on the cover 11, and the cover 11 supports the middle of the plate. At the same time, the height of the cover 11 is adjusted and locked by the bolt 12, so that when both ends of the plate supported by it are located in the opening of the grinding seat 42 after the movement, the upper and lower side walls of the end of the plate are respectively against the upper and lower oblique side walls in the opening of the grinding seat 42;

[0031] Then the motor I34 drives the forward and reverse screw rods 33 to drive the slide seat 32 to slide in the slide groove I31, so as to drive the profile plate 2 and the grinding mechanism 4 to move, so that the grinding seats 42 in the two sets of grinding mechanisms 4 are buckled on both sides of one end of the plate, and at the same time, the moving profile plate 2 drives the gear 77 to engage with the corresponding rack 73 through the rotating shaft 76. When the width of the plate is small, the continuously moving profile plate 2 will drive the gear 77 to squeeze the rack 73 to slide into the strip groove 71 and drive the slide rod 74 to slide in the through hole, and squeeze the spring 7 5 is contracted so that the rack 73 is retracted in the strip groove 71, so that the two groups of grinding seats 42 can clamp and grind plates of different widths, and the transmission mechanism 7 can be smoothly connected with the strip seat 6. In this process, the strip seat 6 will not affect the displacement of the mold plate 2 and the grinding mechanism 4 through the transmission mechanism 7, so as to prevent the problem that the position of the rack 43 is fixed and causes it to affect the displacement of the mold plate 2 and the grinding mechanism 4 through the transmission mechanism 7, and finally makes it only possible to process fixed width plates;

[0032] When the motor II41 drives the grinding seat 42 to rotate to grind the edges of the plate at both ends, the output shaft of the motor II41 will also drive the rack 73 to move forward through the gear ring 78 and the gear 77. At this time, the rack 73 hangs on the side wall of the through hole through the slide rod 74 to push the strip seat 6, the cover body 11 and the plate above it to move forward, so that the grinding seat 42 can grind the entire outer wall of the two ends of the plate. When the strip seat 6 moves forward, it will drive the slider 9 to slide in the slide groove II8.

[0033] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
