Technical Field

[0001] The utility model relates to the technical field of tile leveling machines, in particular to a clamping speed variation structure based on a tile leveling machine. Background Art

[0002] A tile leveler, also known as an automatic leveling machine, is a newer construction tool that can minimize the height difference on the surface of tiles and make the floor or wall flat as a whole.

[0003] Most of the existing tile levelers are composed of a power device, a fixed clamp block and a movable clamp block. When in use, the power device controls the movable clamp block to move horizontally toward the fixed clamp block, thereby pushing the wedge into the tile leveling block to achieve the purpose of tile leveling.

[0004] When the above-mentioned equipment is in use, its power equipment is mostly electric motors. When the motor running speed remains unchanged, the forward and backward speeds of the moving clamp are consistent, resulting in that after leveling each group of tiles, it is necessary to wait for the moving clamp to retreat at a uniform speed before leveling the next group of tiles, resulting in reduced construction efficiency. It needs to be improved. Utility Model Content

[0031] When in use, the power of the driving motor 102 is turned on, and by pressing the control switch, the control switch sends a signal to the control board group 106, and the control board group 106 controls and starts the driving motor 102 to rotate (clockwise), and the driving motor 102 drives the lead screw 101 to rotate in the same direction.

At the same time, the wedge is pulled into the tile leveling block, and it is limited by the fixed clamping block 104, so as to achieve the leveling of the tile group;

[0032] The driving motor 102 controls the screw 101 to rotate forward and reverse, thereby driving the driving nut 103 to move forward and backward, so as to achieve the purpose of intermittent leveling of the tile set.

[0033] Example 2

[0034] Reference Figures 1 to 3 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the device also includes a speed adjustment mechanism 200, the speed adjustment mechanism 200 includes a gear box 201, a one-way bearing, a driving wheel and a driven wheel, the gear box 201 includes a transmission shaft, the transmission shaft is provided with at least two groups, at least one group of transmission shafts is connected to the drive motor 102, at least one group of transmission shafts is connected to the lead screw 101, each group of transmission shafts is arranged with a group of one-way bearings, each group of one-way bearings is arranged with a group of driving wheels, each group of driving wheels is mechanically connected with a group of driven wheels, and the driven wheels are also arranged on the transmission shaft; the speed when the drive motor 102 rotates forward is set as speed one, at this time, the dynamic clamping block 105 moves and gradually approaches the fixed clamping block 104; the speed when the drive motor 102 rotates reversely is set as speed two, at this time, the dynamic clamping block 105 moves and gradually moves away from the fixed clamping block 104, and the speed of speed one is less than the speed of speed two;

[0035] The transmission shaft includes an active transmission shaft 202 and a driven transmission shaft 203, wherein the active transmission shaft 202 is connected to the output end of the driving motor 102, and the output end of the driven transmission shaft 203 is connected to the end of the lead screw 101; the one-way bearing includes a first one-way bearing 204 and a second one-way bearing 205, wherein the first one-way bearing 204 is arranged on the active transmission shaft 202, and the second one-way bearing 205 is arranged on the driven transmission shaft 203; the driving wheel includes a first driving gear 206 and a second driving gear 207, and the driven wheel includes a first driving gear 206 and a second driving gear 207. The first driven gear 208 and the second driven gear 209 are included.

The first driven gear 208 is arranged on the driving transmission shaft 202 on one side of the first driving gear 206.

[0036] The remaining structures are the same as those of Example 1.

[0037] When in use, the driving motor 102 drives the active transmission shaft 202 to rotate, and the active transmission shaft 202 drives the first active gear 206 and the first driven gear 208 to rotate, and through the mechanical transmission connection of each component, drives the second active gear 206 and the second driven gear 209 to rotate synchronously, and then through the rotation of the driven transmission shaft 203, the driven transmission shaft 203 drives the screw 101 connected thereto to rotate synchronously, thereby realizing the tile group leveling function in the above-mentioned embodiment 1.

[0038] When rotating in the forward direction, the driven gear has 22 teeth and the driving gear has 26 teeth, then the input and output are: 26:22=1.182;

[0039] When rotating in the reverse direction, the driven gear is set to have 22 teeth and the driving gear to have 26 teeth, and the input and output are: 22:26=0.846;

[0040] By comparing the forward and reverse rotations, it can be calculated that when the forward and reverse rotation speeds of the motor remain unchanged, the reverse rotation speed is 1.397 times the forward rotation speed (1.182 / 0.846=1.397).

[0041] The speed when the dynamic clamping block clamps the leveling block is speed one (forward rotation), and the speed when the dynamic clamping block returns to the starting position from the clamping position is speed two (reverse rotation). Speed ​​two is greater than speed one, so that it can return to the starting position faster and facilitate the next operation.

[0042] Specifically, when the leveling block is clamped, the drive motor 102 is in a speed regulation state, and the speed regulating mechanism 200 in the gear box 201 runs at speed one. At this time, the rotation speed of the drive motor 102 is lower than 100%; when returning to the starting point, the speed of the drive motor 102 does not change. When returning to the starting point, the speed regulating mechanism 200 in the gear box 201 runs at speed two, and the leveling machine main body mechanism 100 runs at full speed to return to the starting position faster and facilitate the next operation.

[0043] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0044] A one-way bearing is a type of bearing that can rotate freely in one direction but is locked in the other direction. A one-way bearing is also called an overrunning clutch, but is named based on different industries and functions. The metal shell of a one-way bearing contains many rollers, needles or balls, and the shape of its rolling seat (hole) allows it to roll only in one direction, but will generate great resistance in the other direction (the so-called "one-way").

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
