Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Please refer to Figure 1 Figure 6 As shown in the figure,

[0025] Embodiment one: ​

[0026] The utility model provides a kind of plastic tarpaulin stretch heat setting device, including processing box 1, heating box 2 and electric heating net 3, heating box 2 is fixedly connected with the bottom of processing box 1, electric heating net 3 is fixedly installed in the inside of heating box 2, the inside of processing box 1 is provided with two connecting frames 4, the inside of connecting frame 4 is provided with mounting plate 5, the bottom of mounting plate 5 is fixedly installed with a plurality of fans 6, one side of processing box 1 is provided with reciprocating mechanism.

[0027] Reciprocating mechanism includes motor 7 fixedly installed in one side of processing box 1, the output end of motor 7 is fixedly connected with transmission rod 8, one end of transmission rod 8 penetrates to the inside of processing box 1, and is fixedly connected with extrusion block 9, the top of connecting frame 4 is fixedly connected with transmission block 10, the side of two transmission blocks 10 mutually close is fixedly connected with traction rod 11, the side of traction rod 11 close to extrusion plate 12 is fixedly connected with extrusion plate 12, the side of transmission block 10 away from traction rod 11 is fixedly connected with reset spring 13, one end of reset spring 13 is fixedly connected with the inner wall of processing box 1, the top of mounting plate 5 is provided with swing mechanism.

[0028] In the embodiment, considering that the mass of air does not change after heating, the density becomes smaller, and hot air rises and gathers in the upper part of the processing box 1, which will cause the tarpaulin to be unevenly heated when passing through the processing box 1, thereby affecting the subsequent setting effect. Therefore, by setting the reciprocating mechanism, the air inside the processing box 1 can be heated by starting the electric heating net 3 while the plastic tarpaulin is passing through the processing box 1. At the same time, the motor 7 is started, which drives the transmission rod 8 and the extrusion block 9 to rotate. When the protruding end of the extrusion block 9 contacts the extrusion plate 12, the extrusion plate 12 will drive the traction rod 11 and the transmission block 10 to move towards the side close to the reset spring 13. When the extrusion block 9 does not contact the extrusion plate 12, the elastic force generated by the reset spring 13 will push the transmission block 10 to move away from the reset spring 13. The transmission block 10 moves back and forth in sequence, and the connecting frame 4, the rotating block 14, the mounting plate 5, and the fan 6 move back and forth synchronously with the transmission block 10. At the same time, the fan 6 is started to rotate, and the wind force generated by the fan 6 blows the hot air in the upper part of the processing box 1 downward, so that the hot air is evenly distributed in the processing box 1. After that, the tarpaulin can be evenly heated when passing through the processing box 1, thereby improving the subsequent setting effect.

[0029] The top of the transmission block 10 is fixedly connected with a dovetail block 20, and the inner wall of the processing box 1 is provided with a dovetail sliding groove 21 matched with the dovetail block 20.

[0030] In this embodiment, by setting the dovetail block 20 and the dovetail sliding groove 21, when the extrusion block 9 rotates the protruding end to contact the extrusion plate 12, the extrusion plate 12 can only move horizontally along the track of the dovetail block 20 and the dovetail sliding groove 21, and the stability of the extrusion plate 12, the traction rod 11, the transmission block 10 and other structures during movement is improved.

[0031] The surface of the transmission rod 8 is provided with a bearing seat 22, and the transmission rod 8 is rotatably connected with the inner wall of the processing box 1 through the bearing seat 22.

[0032] In this embodiment, by setting the bearing seat 22, the transmission rod 8 and the extrusion block 9 can be supported, and the transmission rod 8 and other structures can only rotate around the bearing seat 22, improving the smoothness during rotation.

[0033] The extrusion block 9 is located between the two extrusion plates 12 and is in an elliptical shape.

[0034] In this embodiment, by setting the extrusion block 9, when the protruding end of the extrusion block 9 contacts the extrusion plate 12, the extrusion plate 12 and other structures are pushed to move away from the extrusion block 9, which plays a transmission role.

[0035] Embodiment two:

[0036] The swing mechanism includes a rotating block 14 fixedly installed on the top of the mounting plate 5, rotating rods 15 fixedly connected to the two sides of the rotating block 14, gears 16 fixedly connected to one end of the rotating rods 15 and penetrating to one side of the connecting frame 4, a toothed plate 17 fixedly connected to the inner wall of the processing box 1 and used in cooperation with the gears 16, and rotating holes 18 formed in the two sides of the connecting frame 4 and used in cooperation with the rotating rods 15.

[0037] In this embodiment, by setting the swing mechanism, when the connecting frame 4 and other mechanisms reciprocate, the gears 16 also move synchronously with the connecting frame 4. When the gears 16 contact the toothed plate 17, the gears 16 drive the rotating rods 15 and the rotating block 14 to swing around the center of the rotating hole 18. When the gears 16 move away from the toothed plate 17, the torsional force of the torsional spring 19 drives the gears 16, the rotating rods 15 and the rotating block 14 to swing back to the original position. The rotating block 14 drives the mounting plate 5 and the fan 6 to swing, so that the fan 6 can effectively blow hot air into the processing box 1, further improving the heating effect of the plastic tarpaulin.

[0038] The surface of the rotating rod 15 is sleeved with a torsional spring 19, one end of the torsional spring 19 is fixedly connected to one side of the connecting frame 4, and the other end of the torsional spring 19 is fixedly connected to one side of the gear 16.

[0039] In this embodiment, by setting the torsion spring 19, when the gear 16 moves to not contact with the toothed plate 17, the torsion generated by the torsion spring 19 will drive the gear 16, the rotating rod 15 and the rotating block 14 to swing in the opposite direction around the center of the rotating hole 18, which plays a role of resetting.

[0040] Working principle: while the plastic tarpaulin passes through the processing box 1, the electric heating net 3 is started to heat the air inside the processing box 1, and at the same time, the motor 7 is started, which will drive the transmission rod 8 and the extrusion block 9 to rotate, when the protruding end of the extrusion block 9 contacts with the extrusion plate 12, the extrusion plate 12 will drive the traction rod 11 and the transmission block 10 to move to the side close to the reset spring 13, when the extrusion block 9 does not contact with the extrusion plate 12, the elastic force generated by the reset spring 13 will push the transmission block 10 to move to the side away from the reset spring 13, and the transmission block 10 will move back and forth in sequence, the connecting frame 4, the rotating block 14, the mounting plate 5 and the fan 6 will move back and forth with the transmission block 10, and the fan 6 is started to rotate, the wind power generated by the fan 6 will blow the hot air at the upper end in the processing box 1 downward, so that the hot air is evenly distributed in the processing box 1, and then the tarpaulin passing through the processing box 1 can be evenly heated, which improves the effect of subsequent shaping.

[0041] When the connecting frame 4 and other mechanisms move back and forth, the gear 16 will also move synchronously with the connecting frame 4, when the gear 16 contacts with the toothed plate 17, the gear 16 will drive the rotating rod 15 and the rotating block 14 to swing around the center of the rotating hole 18, when the gear 16 moves to not contact with the toothed plate 17, the torsion generated by the torsion spring 19 will drive the gear 16, the rotating rod 15 and the rotating block 14 to swing to reset, and the rotating block 14 will drive the mounting plate 5 and the fan 6 to swing, so that the fan 6 can effectively blow the hot air evenly into the processing box 1, which further improves the heating effect of the plastic tarpaulin. It should be noted that the electric heating net 3, the fan 6 and the motor 7 are devices or equipment existing in the prior art, or devices or equipment that can be realized in the prior art, and the power supply composition and principle of the electric heating net 3, the fan 6 and the motor 7 are clear to those skilled in the art, so they will not be described in detail.
