Referring to fig. 1 and 2, an automatic pressing device of a cutting machine includes an operation platform 1 and a gantry moving frame 2 slidably connected to the operation platform 1, wherein a cutting bit 3 and pressing devices disposed on two sides of the gantry moving frame 2 are disposed on the gantry moving frame 2, the pressing devices include a plurality of pressing roller shafts 41 crossing the operation platform 1 and a first driving device 42 driving the pressing roller shafts 41 to ascend and descend, lifting platforms 43 are connected to two ends of the pressing roller shafts 41, the first driving device 42 drives the pressing roller shafts 41 to ascend and descend through the lifting platforms 43, and the cutting bit 3 is located between two of the pressing roller shafts 41. Cutting drill 3 is used for cutting the acrylic plate, and cutting drill 3 can rotate under the drive of electric power, then moves about along longmen moving frame 2, cuts ya keli. And the gantry moving frame 2 is driven by the screw rod driving device to move back and forth along the edge of the working platform 1, so that the acrylic plate can be cut by matching with the movement of the cutting drill 3, and the acrylic plate can be cut into various required shapes. The pressing roller 41 is provided across the work platform 1 and can be moved together under the belt of the gantry 2. The cutting drill 3 is located between two of the pressing roller shafts 41, and the pressing roller shafts 41 are arranged on two sides of the cutting drill 3 to assist in pressing the acrylic plates. When using, at first shop an acrylic plate raw materials on operation platform 1, afterwards first drive arrangement 42 drives elevating platform 43 drives compress tightly roller 41 and down, let compress tightly roller 41 and provide certain normal pressure for the acrylic plate on the operation platform 1, let the curved condition of acrylic plate elimination of cutting drill bit 3 both sides, guarantee that cutting drill bit 3 is when cutting acrylic plate, acrylic plate is the laminating on operation platform 1, can not have any bending, guarantees that the shape after the cutting of acrylic plate can not warp, improves the yield of acrylic plate cutting to reduction in production cost. The compressing roller shafts 41 are located on the front side and the rear side of the cutting drill 3, the compressing roller shafts 41 cannot be touched when the cutting drill 3 moves along the gantry moving frame 2, the compressing roller shafts 41 can also roll back and forth along with the gantry moving frame 2, the compressing roller shafts 41 can be pressed to provide positive pressure for the acrylic plate no matter where the cutting drill 3 moves, the compressing roller shafts 41 cannot be collided by the cutting drill 3, and the use is very convenient.

Preferably, for better compaction effect and better movement of the gantry 2, the two compaction rollers 41 are distributed on both sides of the cutting bit 3. Too many will increase a burden of pressing roller 41, the removal of longmen carriage 2 of being not convenient for, pressing roller 41 has two moreover can guarantee the straightness of ya keli board, the resource utilization maximize.

Preferably, in order to prevent the acrylic plate from being deformed under the positive pressure of the pressing roller shaft 41, the lifting table 43 is provided with a pre-pressing roller shaft 44 corresponding to a side of the pressing roller shaft 41 away from the cutting bit 3, and the height of the pre-pressing roller shaft 44 is greater than that of the pressing roller shaft 41. Namely, two prepressing rollers 44 are distributed on one side of the pressing roller shaft 41 far away from the cutting drill 3, the height of the prepressing rollers 44 is 0.5-2mm higher than that of the pressing roller shaft 41, so that when the pressing roller shaft 41 presses an acrylic plate, the prepressing rollers 44 can ensure that the acrylic plate on the outer sides of the two pressing roller shafts 41 is greatly deformed, the acrylic plate can be prepressed in advance, the pressing resistance of the pressing roller shaft 41 is reduced, the gantry moving frame 2 can conveniently move back and forth, and the cutting drill 3 can be conveniently cut.

Preferably, in order to avoid the pre-pressing roller shaft 44 from crushing the acrylic plate, the pre-pressing roller shaft 44 is sleeved with a first rubber sleeve 441. The first rubber sleeve 441 is sleeved on the prepressing roll shaft 44, so that the situation that the acrylic plate is scratched and crushed by the prepressing roll shaft 44 can be reduced, and the acrylic plate can be better molded.

Preferably, in order to better connect the pressing roller shaft 41, the pressing roller shaft 41 is connected to the elevating table 43 through a connecting table 45. Add between compressing tightly roller 41 and elevating platform 43 and be connected platform 45, wherein connect the height and the size of platform 45 and can set up according to actual conditions, let compressing tightly roller 41 install in suitable position, facilitate the use. In order to control the pressure received by the acrylic plate, a pressure sensor 46 is disposed on the connection table 45, the pressure sensor 46 is electrically connected to the control box 5, and the first driving device 42 is electrically connected to the control box 5. That is, the connecting station 45 can detect the pressure applied to both ends of the pressing roller 41, that is, the positive pressure applied to the acrylic sheet. The control box 5 is provided with a PLC controller which can receive signals transmitted by the pressure sensor 46 and then control the first driving device 42 to drive the lifting platform 43 to lift. The controller is provided with an acrylic plate positive pressure standard value, when the pressure sensor 46 detects that the pressure value on the connecting table 45 does not reach the positive pressure standard value, the control box 5 controls the first driving device 42 to drive the lifting table 43 to descend, so that the pressure value is increased until the pressure value reaches the positive pressure standard value; if the pressure value is too large, the control box 5 controls the first driving device 42 to drive the lifting platform 43 to ascend, and the pressure value is reduced until the pressure value reaches a positive pressure standard value. Therefore, the size of the positive pressure on the acrylic plate is basically unchanged, the acrylic plate is not crushed, and the acrylic plate can be molded better. The first driving device 42 is preferably an air cylinder, but the first driving device 42 may be a linear driving device such as an oil cylinder and a screw driving device.

Preferably, in order to avoid the acrylic plate from being scratched by the pressing roller shaft 41, the pressing roller shaft 41 is sleeved with the second rubber sleeve 411, so that the friction force between the pressing roller shaft 41 and the acrylic plate is increased through the second rubber sleeve 411, the relative movement between the pressing roller shaft 41 and the acrylic plate is avoided, and therefore the acrylic plate is prevented from being scratched by the pressing roller shaft 41.

Compared with the prior art, the utility model discloses a set up longmen and remove 2 loads cutting bit 3, and all be provided with in 3 both sides of cutting bit and compress tightly roller 41, then can let the inferior gram force board of 3 both sides of cutting bit eliminate crooked condition, guarantee cutting bit 3 when cutting inferior gram force board, the laminating of inferior gram force board is on operation platform 1, avoid appearing the crooked condition of inferior gram force board, guarantee that the shape of inferior gram force board after the cutting can not warp, improve the yield of inferior gram force board cutting, thereby reduce manufacturing cost.

The above is only the preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should fall into the protection scope of the present invention as long as it is reached by any of the same or similar means.
