[0031] Therefore, please refer to Figures 1-4 , the present utility model provides a building formwork grinding device, including:

[0032] A grinding table 1, a support frame 2 is fixedly connected to the rear edge of the top of the grinding table 1, a moving plate 3 with an I-shaped vertical section is slidably connected to the support frame 2, a lifting seat 31 with an I-shaped cross section is slidably connected in a lifting channel provided on the moving plate 3, a motor a32 is fixedly connected to the lifting seat 31 at one end away from the middle of the top of the grinding table 1, the output shaft of the motor a32 passes through the lifting seat 31, and is fixedly connected to a grinding roller 33, an electric push rod 34 is fixedly connected to the inner top wall of the lifting channel, and the telescopic end of the electric push rod 34 is fixedly connected to the top of the lifting seat 31;

[0033] It also includes an adjustable reciprocating transmission structure 4 and a synchronous positioning structure 5.

[0035] The electric push rod 34 is provided to facilitate the height of the grinding roller 33 to be suitable for building templates of different thicknesses.

[0036] Further Figures 1-3 As shown, it is worth explaining in detail that in order to facilitate the reciprocating motion of the grinding roller 33 driven by the motor a32, an adjustable reciprocating transmission structure 4 is provided, including a support plate 41 fixedly connected to the middle of the top end of the support frame 2, and a motor b42 is fixedly connected to the front side wall of the support plate 41. The output shaft of the motor b42 passes through the support plate 41 device and is fixedly connected to a turntable 43.

The L-shaped transmission rod 45 is provided with a transmission channel matching the transmission column 44, and the bottom end of the L-shaped transmission rod 45 is fixedly connected to the rear side wall of the movable plate 3.

[0037] The length of the transmission channel is greater than the diameter of the rotating disk 43 , and the width of the transmission channel is equal to the diameter of the transmission column 44 .

[0038] Further, as shown in FIG. 4, it is worth specifically explaining that in order to facilitate the above-mentioned reciprocating drive structure to promote the grinding roller 33 to grind building templates of different lengths, an adjusting member is provided, including a slider 442 fixedly connected to one end of the transmission column 44 facing the turntable 43. The cross-section of the slider 442 is in a convex structure. The slider 442 is slidably connected to a chute 443 provided on the surface of the turntable 43.

[0039] Wherein, threaded channels for cooperating with the hand-tightening screw 441 are provided on the transmission column 44 and the slider 442.

[0040] Further, as Figures 2-3 shown, it is worth specifically explaining that in order to be able to drive the grinding roller 33 to fit on the top of the building template by means of the lifting seat 31 and realize the clamping and fixing of the building template in a linked manner, a synchronous positioning structure 5 is provided, including a rolling ball 52 rotatably connected in a ball groove provided at the bottom end of the lifting seat 31. The bottom end of the rolling ball 52 is movably lapped on the top end of the lifting rod 53. The bottom end of the lifting rod 53 is fixedly connected with two symmetrically arranged movable rods 59. The bottom ends of the movable rods 59 are respectively movably inserted into movable channels provided at the top end of the grinding table 1. Springs b510 are movably sleeved on the outer sides of the movable rods 59. The top ends of the two springs b510 are respectively connected to the bottom end of the lifting rod 53 and the top end of the grinding table 1. A pressing rod 54 is fixedly connected to the middle of the bottom end of the lifting rod 53. The pressing rod 54 slides in a lifting channel provided at the top end of the grinding table 1. The bottom end of the pressing rod 54 is provided with an inclined surface b. A guide seat 55 with a convex cross-section is movably lapped on the front side wall of the pressing rod 54. The guide seat 55 is slidably connected to a guide groove provided at the top end of the grinding table 1. The guide groove is communicated with the lifting channel. A clamping plate b58 is fixedly connected to the top end of the guide seat 55. A clamping plate a51 is fixedly connected to the front side edge of the top end of the grinding table 1. An inclined surface a56 for cooperating with the inclined surface b is provided at the rear end of the guide seat 55. The front end of the guide seat 55 is connected to the inner wall of the guide groove through a spring a57.

[0041] Among them, spring a57 is in a compressed state in the attached drawing, and the two springs b510 are also in a compressed state. In addition, when the seat 31 to be lifted and lowered is pulled up by the electric push rod 34, under the action of the two springs b510, the lifting rod 53 is driven to drive the pressing rod 54 to move up, and the bottom inclined surface b of the pressing rod 54 can rise above the top of the guiding groove. In addition, under the reverse action of the spring a57, the guiding seat 55 can make the inclined surface a56 retreat to directly below the inclined surface b, so as to ensure that when the pressing rod 54 moves down next time, the inclined surface b can continue to squeeze the inclined surface a56; the depth of the lifting channel is the same as that of the moving channel; the setting of the rolling ball 52 can reduce the friction coefficient between the bottom end of the seat 31 to be lifted and lowered and the top end of the lifting rod 53 when the grinding roller 33 moves back and forth left and right.

[0042] In summary: when using this building formwork grinding device, the building formwork to be ground can be placed between the clamping plate a51 and the clamping plate b58. By starting the electric push rod 34, the seat 31 to be lifted and lowered is pushed down, and then the rolling ball 52 squeezes the lifting rod 53, so that the bottom inclined surface b of the pressing rod 54 compresses the rear inclined surface a56 of the guiding seat 55, so that the clamping plate b58 connected to the top end of the guiding seat 55 moves towards the clamping plate a51, thus facilitating the clamping and fixing of the building formwork. At the same time, the grinding roller 33 is attached to the top of the building formwork. Furthermore, by starting the motor a32 and the motor b42, the turntable 43 rotates, and with the cooperation of the transmission column 44 and the L-shaped transmission rod 45, the moving plate 3 drives the grinding roller 33 driven by the motor a32 on the seat 31 to move back and forth left and right, so as to efficiently grind the top of the building formwork with good grinding effect.
