Description

Technical Field

[0001] The utility model relates to the field of tarpaulin production equipment, in particular to a high-frequency automatic tarpaulin cutting machine. Background Art

[0002] Tarpaulin is a waterproof material with high strength, good toughness and softness. During the manufacturing process, the tarpaulin needs to be cut into predetermined sizes.

[0003] Existing tarpaulin cutting machines typically consist of a frame, a conveyor belt mounted on the frame, a high-frequency vibrating blade, and a linear module. The conveyor belt drives the tarpaulin along the length of the frame, while the linear module drives the high-frequency vibrating blade along the width of the frame. The high-frequency vibrating blade generates high-frequency vibrations, cutting the tarpaulin as it moves across the width of the frame. However, these tarpaulin cutting machines often unwind the tarpaulin from an unwinder and manually lay it flat on the conveyor belt. This manual laying process is inefficient, leading to low cutting efficiency for the cutting machine.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] In order to improve or solve the technical problem of low efficiency in manually laying tarpaulins in the prior art, the utility model provides a high-frequency automatic tarpaulin cutting machine. The high-frequency automatic tarpaulin cutting machine comprises: a frame having a laying table for placing the tarpaulin; a reeling structure comprising a reeling roller and a guide roller mounted on the frame; a cutting structure comprising a high-frequency vibrating knife suitable for cutting the tarpaulin, a first linear module driving the high-frequency vibrating knife to slide along the length direction of the frame, and a second linear module driving the high-frequency vibrating knife to move along the width direction of the frame; a traction structure comprising a translation structure mounted on the frame, a lifting structure connected to the translation structure, and a pneumatic suction cup mounted on the lifting structure; a plurality of the pneumatic suction cups are arranged side by side and at intervals along the width direction of the frame, and are configured to pull the tarpaulin to be laid flat on the laying table.

[0006] The utility model discloses a high-frequency automatic tarpaulin cutting machine, which includes a frame, an unwinding structure, a cutting structure, and a traction structure. The frame is used to install the above-mentioned structures, the unwinding structure includes an unwinding roller and a guide roller, the unwinding roller is used to unwind the tarpaulin roll, and the guide roller is used to guide the unwound tarpaulin. The traction structure includes a translation structure, a lifting structure, and a pneumatic suction cup. The pneumatic suction cup is used to adsorb the tarpaulin; the lifting structure is used to drive the pneumatic suction cup to rise and fall, so that the pneumatic suction cup is close to or away from the tarpaulin; the translation structure is used to drive the pneumatic suction cup to move, so that the tarpaulin is spread flat on the laying table. A plurality of pneumatic suction cups are arranged along the width direction of the frame, which can better adsorb and spread the tarpaulin. The cutting structure includes a high-frequency vibrating knife, a first linear module, and a second linear module. The high-frequency vibrating knife is used to cut the tarpaulin; the second linear module is used to drive the high-frequency vibrating knife to move along the width direction of the frame, thereby cutting the tarpaulin in the length direction; the first linear module is used to drive the high-frequency vibrating knife to move along the length direction of the frame, so that after cutting, it moves toward the unwinding structure to avoid the traction structure pulling the tarpaulin. Through the above-mentioned settings, the utility model is a high-frequency automatic tarpaulin cutting machine that uses pneumatic suction cups to pull and flatten the tarpaulin. Compared with manual flattening, the work efficiency is higher and the cutting efficiency of the corresponding cutting machine is higher; multiple pneumatic suction cups are arranged side by side along the width direction of the frame, which can relatively completely absorb the tarpaulin in the width direction of the tarpaulin to ensure the flattening effect of the tarpaulin.

[0007] Furthermore, the pneumatic suction cups are arranged in two rows side by side along the length direction of the frame.

[0008] Furthermore, the translation structure includes a support mounted on the frame, a drive shaft mounted in the support, a translation seat threadedly connected to the drive shaft, and a power source for driving the drive shaft to rotate.

[0009] Furthermore, the lifting structure includes a lifting cylinder installed on the translation seat, and a suction cup frame on which the pneumatic suction cup is installed; the suction cup frame is fixedly connected to the lifting cylinder.

[0010] Furthermore, the suction cup frame includes a mounting rod connected to the pneumatic suction cup and a connecting rod connected to the mounting rod; a slide groove is provided on the mounting rod, and a slider matching the slide groove is provided on the pneumatic suction cup.

[0011] Furthermore, a threaded hole is provided on the sliding block, and a limiting bolt is arranged in the threaded hole to abut against the mounting rod to fix the pneumatic suction cup.

[0012] Furthermore, a limit stop is arranged on the mounting rod.

[0013] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The use of pneumatic suction cups to pull and lay the tarpaulin flat is more efficient than manual laying, and the corresponding cutting efficiency of the cutting machine is higher; multiple pneumatic suction cups are arranged side by side along the width direction of the frame, which can relatively completely absorb the tarpaulin in the width direction of the tarpaulin to ensure the flat laying effect of the tarpaulin;

[0015] (2) Two rows of pneumatic suction cups are set up to enhance the adsorption effect on the tarpaulin and prevent the tarpaulin from falling during the traction process. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to improve or solve the technical problem of low efficiency in manually laying tarpaulins in the prior art, the present invention provides a high-frequency automatic tarpaulin cutting machine. The high-frequency automatic tarpaulin cutting machine comprises: a frame 1 having a laying table 11 for placing the tarpaulin; a reeling structure 2 comprising a reeling roller 21 and a guide roller 22 mounted on the frame 1; a cutting structure 3 comprising a high-frequency vibrating knife 33 suitable for cutting the tarpaulin, a first linear module 31 for driving the high-frequency vibrating knife 33 to slide along the length direction of the frame 1, and a second linear module 32 for driving the high-frequency vibrating knife 33 to move along the width direction of the frame 1; a traction structure 4 comprising a translation structure 41 mounted on the frame 1, a lifting structure 42 connected to the translation structure 41, and a pneumatic suction cup 43 mounted on the lifting structure 42; a plurality of pneumatic suction cups 43 are arranged side by side and at intervals along the width direction of the frame 1, and are configured to pull the tarpaulin to be laid flat on the laying table 11.

[0025] Figure 1 This is a schematic diagram of an embodiment of a high-frequency automatic tarpaulin cutting machine of the utility model. Figure 1 As shown, in one or more embodiments, the utility model provides a high-frequency automatic tarpaulin cutting machine including a frame 1 , an unwinding structure 2 , a cutting structure 3 and a traction structure 4 .

[0026] Continue to see Figure 1 The frame 1 includes a relative upper half and a lower half. The lower half is a roughly rectangular box, and a laying table 11 is provided in the lower half, and the laying table 11 is exposed in the lower half. Specifically, the laying table 11 is a conveyor belt that circulates along the length direction of the frame 1, which is used to lay the tarpaulin and drive the cut tarpaulin to move. The cut tarpaulin can be manually stored and folded, or it can be temporarily stored at the end of the frame 1 under the drive of the laying table 11. Furthermore, the upper half includes two side brackets installed on the lower half and arranged oppositely, and the unwinding mechanism, cutting structure 3 and traction structure 4 are all installed on the upper half. Specifically, the side bracket is roughly rectangular plate-shaped. The length of one of the side brackets is greater than that of the other side bracket, so that the part of the side bracket close to the head end of the frame 1 is exposed.

[0027] Continue to see Figure 1, the unwinding structure 2 is installed on the exposed part of the side bracket, so as to facilitate the placement of the tarpaulin roll. In one or more embodiments, the unwinding structure 2 includes an unwinding roller 21 and a guide roller 22, and the unwinding roller 21 and the guide roller 22 are both installed on the side bracket at one end and suspended at the other end. Furthermore, there are two unwinding rollers 21, and the two unwinding rollers 21 are arranged side by side, so that after one unwinding roller 21 finishes unwinding, the other unwinding roller 21 can be used for unwinding. The guide roller 22 is close to the laying table 11 to change the conveying direction of the tarpaulin. Furthermore, the unwinding roller 21 can be an unpowered roller, and the conveyance of the tarpaulin depends on the traction of the traction structure 4. Alternatively, the unwinding roller 21 is a powered roller, the unwinding roller 21 unwinds autonomously, and the traction structure 4 pulls the unwound tarpaulin.

[0028] Continue to see Figure 1 , the cutting structure 3 is arranged above the laying table 11. In one or more embodiments, the cutting structure 3 includes a first linear module 31 installed on the frame 1, a second linear module 32 installed on the first linear module 31, and a high-frequency vibrating knife 33 installed on the second linear module 32.

Specifically, the first linear module 31 includes two modules arranged opposite to each other, and the two modules are respectively installed on two side brackets and driven by two drive motors. The two ends of the second linear module 32 are respectively installed on the two first linear modules 31 through sliders 431. The high-frequency vibrating knife 33 is installed on the second linear module 32 through a knife holder, and is raised and lowered by the knife holder to move closer to or away from the tarpaulin. The high-frequency vibrating knife 33 cuts the tarpaulin through the vibration generated by the high-frequency current. The high-frequency vibrating knife 33 and the knife holder are existing products and will not be described here.

[0029] Figure 2 yes Figure 1 The enlarged schematic diagram of point A in the middle, Figure 3 This is a schematic diagram of a suction cup frame in a high-frequency automatic tarpaulin cutting machine of the utility model. Figure 1 、 Figure 2 and Figure 3As shown, in one or more embodiments, the traction structure 4 includes a translation structure 41 mounted on the frame 1, a lifting structure 42 connected to the translation structure 41, and a pneumatic suction cup 43 mounted on the lifting structure 42. The translation structure 41 extends along the length of the frame 1. Furthermore, two groups of pneumatic suction cups 43 are provided, and the two groups of pneumatic suction cups 43 are arranged side by side along the length of the frame 1. Each group of pneumatic suction cups 43 is provided with multiple pneumatic suction cups, and the multiple pneumatic suction cups 43 are evenly and spaced apart. Furthermore, the translation structure 41 extends along the length of the frame 1 and includes a support 411 fixed to the frame 1, a drive shaft 412 mounted in the support 411, a translation seat 413 threadedly connected to the drive shaft 412, and a power source 414 that drives the drive shaft 412 to rotate. Two translation structures 41 are provided, and the two translation structures 41 are arranged opposite each other and mounted on two side brackets respectively. The support 411 and the drive shaft 412 partially overlap with the first linear module 31 in the length direction of the frame 1, so that the pneumatic suction cup 43 can move to the leftmost end, thereby sucking the uncut tarpaulin and then pulling the tarpaulin to the right end. Specifically, the drive shaft 412 is a threaded rod shaft, and the forward and reverse rotation of the drive shaft 412 drives the translation seat 413 to move left and right. Furthermore, the lifting structure 42 includes a lifting cylinder 421 installed on the translation seat 413, and a suction cup frame 422 connected to the lifting cylinder 421. The cylinder seat of the lifting cylinder 421 is installed on the translation seat 413 by bolts, and the cylinder shaft is fixedly connected to the suction cup frame 422 by bolts. Furthermore, the suction cup frame 422 includes a connecting rod 4221 connected to the lifting cylinder 421, and a mounting rod 4222 for mounting the pneumatic suction cup 43. The mounting rod 4222 extends along the width direction of the frame 1, and the connecting rod 4221 extends along the length direction of the frame 1. Two mounting rods 4222 are provided, one for mounting two sets of pneumatic suction cups 43. Multiple connecting rods 4221 are provided for connecting the mounting rods 4222. The mounting rods 4222 and the connecting rods 4221 are fixedly connected by bolts. Part of the connecting rods 4221 is connected to the lifting cylinder 421. Furthermore, the pneumatic suction cup 43 is movably mounted on the mounting rod 4222. A chute is provided on the mounting rod 4222, extending along the length of the mounting rod 4222. A slider 431 is provided on the pneumatic suction cup 43 to match the chute. The slider 431 is arranged in the chute, thereby limiting the position of the pneumatic suction cup 43 in the vertical direction. Furthermore, a threaded hole is provided on the slider 431, and a limit bolt 432 is arranged in the threaded hole. The limit bolt 432 passes through the bolt hole and abuts against the mounting rod 4222, fixing the slider 431 in the chute by pressure to prevent the slider 431 from moving along the chute. When the position of the pneumatic suction cup 43 needs to be adjusted, the limiting bolt 432 is loosened and the position of the slider 431 is adjusted; when the pneumatic suction cup 43 needs to be fixed, the limiting bolt 432 is tightened to fix the pneumatic suction cup 43 on the mounting rod 4222.Further, a limit stopper 44 is also provided on the mounting rod 4222. The limit stopper 44 is a hard limit, and its lower end is slightly higher than the lower end of the pneumatic sucker 43 to prevent the pneumatic sucker 43 from colliding with the laying platform 11 during the pressing process.
