[0039] Both ends of the first connecting column 11 are provided with an expansion hole 13 with a longitudinal section in rectangular shape, an expansion column 14 is movably arranged in the expansion hole 13, the outer wall of the expansion column 14 is movably attached to the expansion hole 13, one end of the expansion column 14 is located outside the expansion hole 13, and the other end is provided with an elastic element 15 between the outer end of the expansion column 14 and the inner end of the expansion hole 13, both ends of the elastic element 15 are respectively connected to the expansion column 14 and the inner wall of the expansion hole 13, the outer end of the expansion column 14 is provided with a linkage part 16 perpendicular to the expansion column 14, the free end of the linkage part 16 is provided with a locking cylinder 17, the locking cylinder 17 is in the shape of a cover with an opening facing the middle of the first connecting column 11.

[0040] Both ends of the second connecting column 12 are provided with a locking column 18, when the compensation sheet 9 is wound on the outer wall of the first connecting column 11 or the second connecting column 12, and the locking column 18 is inserted into the locking cylinder 17, the elastic element 15 is in the original length or elongation state.

[0041] The outer wall of the telescopic column 14 is provided with an anti-dropping part 19, the side wall of the first connecting column 11 is provided with a long strip-shaped movable opening 20, the anti-dropping part 19 is movably located in the movable opening 20, the elastic member 15 is always in an elongated state, and the anti-dropping part 19 is in a separated state with the compensation sheet 9.

[0042] When the anti-dropping part 19 abuts against the inner end of the movable opening 20, the projections of the two ends of the first connecting column 11 in the vertical direction are located between the projections of the two locking cylinders 17 in the vertical direction.

[0043] The locking cylinder 18 is in a cylindrical shape, and the periphery of the free end of the locking cylinder 18 is in a chamfered or rounded shape.

[0044] The utility model provides a cutting table for tarpaulin, all control valves 6 are preferably in the open state in actual use, then the worker draws the free end of tarpaulin to the appropriate position on the support table 1, the worker manually closes the control valve 6 on the downstream side of the free end of tarpaulin, and then starts the negative pressure pump, through the total suction pipe 5 and suction pipe 4, all suction hoods 3 on the upstream side of the closed control valve 6 can have negative pressure, so that the tarpaulin can be adsorbed on the support table 1, so that only one control valve 6 needs to be controlled each time, and the tarpaulin can be fixed on the support table 1 by only one negative pressure pump. The power of the negative pressure pump can be adjusted according to the length of the tarpaulin in actual use, that is, if the tarpaulin on the support table 1 is short, the negative pressure pump only needs to have small power, and if the tarpaulin on the support table 1 is long, the power of the negative pressure pump needs to be adjusted, so as to ensure that the tarpaulin can reach the required stability with minimum power. According to the actual situation, several negative pressure pumps can be connected to the total suction pipe 5, and several negative pressure pumps can be started simultaneously if the tarpaulin is too long. Although this method also needs several negative pressure pumps, compared with the current situation that each suction hood 3 has a negative pressure pump, the cost is greatly reduced. Since only one (or two on both sides) control valve 6 needs to be controlled to fix tarpaulins of different lengths, the operation is more convenient.

[0045] In actual operation, the worker pulls the end of the tarpaulin to the appropriate position on the support table 1, if the end of the tarpaulin is located between two adjacent air exhaust hoods 3, no compensation sheet 9 is needed; but if the end of the tarpaulin is located above an air exhaust hood 3 (this case is more common), the worker also needs to manually attach the lower side of the compensation sheet 9 (preferably made of the same material as the tarpaulin) to the support table 1, and make the upstream end of the compensation sheet 9 abut the downstream end of the tarpaulin; since the width of the compensation sheet 9 is greater than the width of the air exhaust hood 3, the air exhaust hood 3 below the end of the tarpaulin is completely covered by the compensation sheet 9 and the end of the tarpaulin, and the worker needs to operate the control valves 6 located below the end of the tarpaulin. After the negative pressure pump is started, negative pressure is formed in all air exhaust hoods 3 on the upstream side of the control valves 6, and the entire tarpaulin is adsorbed on the support table 1, and due to the presence of the compensation sheet 9, air cannot directly enter the air exhaust hood 3 at the end of the tarpaulin, so the stability of the adsorption of the tarpaulin can be guaranteed.

[0046] After the compensation sheet 9 is placed in position, the first connecting column 11 is clamped into two clamping grooves 10 on one side, and the second connecting column 12 is clamped into two clamping grooves 10 on the other side, so that the first connecting column 11 and the second connecting column 12 can temporarily fix the position of the compensation sheet 9, which is convenient for subsequent adsorption, and also ensures the stability of the position of the part of the compensation sheet 9 that is not adsorbed.

[0047] When the air exhaust pipe 4 exhausts the air in the air exhaust hood 3, the hole diameter on the air equalization honeycomb plate 8 is very small, so that the air pressure of the part of the air exhaust hood 3 above the air equalization honeycomb plate 8 is relatively balanced, making the adsorption of the tarpaulin more uniform.

[0048] When the tarpaulin is cut and the compensation sheet 9 is no longer needed, the worker first removes the first connecting column 11 and the second connecting column 12 from the clamping grooves 10, then winds the compensation sheet 9 around the first connecting column 11 or the second connecting column 12, then manually pulls the linkage 16 outward, and makes the locking cylinder 17 not affect the movement of the locking column 18; after the winding of the compensation sheet 9 is completed, the linkage 16 is released, and under the action of the tension of the elastic member 15, the locking sleeve is sleeved on the locking column 18; since the telescopic column 14 cannot rotate relative to the first connecting column 11, the compensation sheet 9 wound around the first connecting column 11 or the second connecting column 12 can be stably pressed between the first connecting column 11 and the second connecting column 12, so that the compensation sheet 9, the first connecting column 11 and the second connecting column 12 can be self-locked, and can be conveniently stored, moved, etc. When winding the compensation sheet 9, the anti-dropping part 19 abuts against the inner end of the movable port 20, so that the locking cylinder 17 does not affect the winding of the compensation sheet 9, and the operation is more convenient.

[0049] In still another embodiment, the support platform 1 has several fixing units for fixing the tarpaulin under the support platform 1, and each fixing unit comprises the above suction hood 3 (group), the total suction pipe 5, and a negative pressure pump, and so on. Thus, although several negative pressure pumps are needed, compared with the case that a negative pressure pump is needed for each suction hood 3, the cost of the equipment can be reduced, and the operation convenience is also higher.

[0050] The above description is only a description of the preferred embodiments of the present application, and is not any limitation on the scope of the present application. Any modification or modification of the above disclosure by a person skilled in the art belongs to the protection scope of the claims.
