[0002] Tarpaulin, also known as waterproof cloth, is generally made of polyester cloth and PVC material coating. This tarpaulin has high tensile strength, excellent toughness and softness. Nowadays, tarpaulins are generally divided into two categories: coarse tarpaulin and fine tarpaulin. Among them, coarse tarpaulin is also called tarpaulin cover cloth. The fabric is strong and fold-resistant, and has good waterproof properties. It is often used in automobile transportation, open-air warehouse covering and tent making.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5 As shown, the utility model provides a folding-resistant PVC tarpaulin coating pretreatment device, comprising:

Due to the meshing between the gear 7 and the tooth plate 8, the two tooth plates 8 will start to move in opposite directions as a whole, so that the flattening plate 9 will flatten the wrinkles.

[0033] A pneumatic cylinder 10 located above the connecting frame 3 is fixedly mounted on the upper surface of the mounting shell 2 , and a bottom end of the pneumatic cylinder 10 penetrates the mounting shell 2 and extends to the upper surface of the connecting frame 3 and is fixedly connected to the connecting frame 3 .

[0034] When the pneumatic cylinder 10 is in operation, the connecting frame 3 as a whole will start to move toward the cloth.

[0035] Among them, the outer surfaces of the front and rear sides of the hollow block 4 are movably connected to the limit strip 11, the limit strip 11 is fixedly connected to the inner surface of the mounting shell 2, the lower surface of the limit strip 11 is fixedly connected to a spreading platform 13, the lower surface of the spreading platform 13 is fixedly connected to the upper surface of the bed 1, and the upper surface of the spreading platform 13 is fixedly connected to a material blocking plate 12 located on the inner side of the limit strip 11.

[0036] The limiting strip 11 limits the movement of the hollow block 4, thereby ensuring the stability of the entire hollow block 4 during movement.

[0037] Among them, the outer surfaces of the front and rear sides of the mounting shell 2 are provided with sliding grooves 14, and the inner surfaces of the sliding grooves 14 are movably connected with moving blocks 15. The left surfaces of the mounting shell 2 and the moving block 15 are fixedly installed with No. 2 motors 16, and the other end of the output shaft of the No. 2 motor 16 is fixedly sleeved with a No. 2 circular shaft 17. There are two No. 2 circular shafts 17, and the right ends of the two No. 2 circular shafts 17 respectively penetrate the mounting shell 2 and the moving block 15 and extend to the right ends of the mounting shell 2 and the moving block 15 respectively.

[0038] Due to the design of the sliding groove 14 , the moving block 15 can move along the inner surface of the sliding groove 14 as a whole.

[0039] The outer surfaces of the two second circular shafts 17 are fixedly sleeved with flattening rollers 18 located on the inner side of the mounting shell 2 . There are two flattening rollers 18 , and the sizes of the two flattening rollers 18 are the same.

[0040] When the two flattening rollers 18 clamp the cloth, the two flattening rollers 18 will flatten the cloth.

[0041] Among them, the outer surface of the mounting shell 2 is fixedly connected with a fixing plate 19 located on the right side of the sliding groove 14, and the right surface of the fixing plate 19 is fixedly installed with a No. 3 motor 20, and the other end of the output shaft of the No. 3 motor 20 is fixedly sleeved with a lead screw 21, and the left end of the lead screw 21 penetrates the fixing plate 19 and extends to the left side of the fixing plate 19, and the upper side of the left surface of the fixing plate 19 is fixedly connected with a limiting rod 22, and the right end of the limiting rod 22 penetrates the fixing plate 19 and extends to the right side of the fixing plate 19, and the outer surface of the limiting rod 22 and the inner surface of the fixing plate 19 are fixedly sleeved.

[0042] When the third motor 20 is running, the lead screw 21 will start to rotate.

[0043] Among them, the outer surface of the lead screw 21 is threadedly sleeved with an articulated block 23, the inner surface of the upper side of the articulated block 23 is movably sleeved with the outer surface of the limiting rod 22, the top of the articulated block 23 is hinged with a connecting rod 24, and the other end of the connecting rod 24 is hinged to the right side of the moving block 15.

[0044] When the hinge block 23 starts to move rightward, the connecting rod 24 starts to rotate, and the other end of the connecting rod 24 drives the entire moving block 15 , so that the entire moving block 15 starts to move downward along the inner surface of the sliding slot 14 .

[0045] The working principle and use process of this utility model:

[0046] First, the operator places the cloth between the two flattening rollers 18 and then starts the No. 3 motor 20. As the No. 3 motor 20 runs, the lead screw 21 begins to rotate. At this time, the hinge block 23 begins to move to the right driven by the lead screw 21, and the movement of the hinge block 23 causes the connecting rod 24 to start rotating, so that the moving block 15 as a whole begins to move downward along the inner surface of the sliding groove 14 driven by the other end of the connecting rod 24. Finally, both flattening rollers 18 will contact the cloth and begin to flatten the creases. At this time, the operator starts the No. 2 motor 16. The operation of the No. 2 motor 16 causes the No. 2 circular shaft 17 and the flattening roller 18 to start rotating, and the processed cloth will be driven by the flattening roller 18 and transported to the outside of the entire bed 1.

[0047] When wrinkles appear on the upper surface of the cloth, the operator starts the pneumatic cylinder 10 and the No. 1 motor 5. The operation of the pneumatic cylinder 10 will cause the connecting frame 3 to move toward the cloth as a whole, and the operation of the No. 1 motor 5 will cause the No. 1 circular shaft 6 and the gear 7 to start rotating. Since the gear 7 and the tooth plate 8 are meshed with each other, the two tooth plates 8 as a whole will move in opposite directions along the inner surface of the hollow block 4 driven by the meshing of the gear 7. In this process, the two spreading plates 9 will flatten the wrinkles on the cloth, thereby ensuring the smoothness of the cloth surface after pretreatment.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
