Description

Technical Field

[0001] The utility model relates to the technical field of tarpaulin production, in particular to a PE tarpaulin coating device. Background Art

[0002] With the rapid development of industries such as construction, agriculture, and logistics, the demand for waterproof, sun-proof, and durable tarpaulins is increasing. PE tarpaulins have become popular products on the market due to their excellent waterproofness, weather resistance, and economy. With the continuous advancement of materials science and manufacturing technology, the production process and performance of PE tarpaulins are also constantly improving. The coating device is a key equipment in the production process of PE tarpaulins. Its technical level and performance directly affect the quality and production efficiency of the tarpaulins. With the continuous innovation of technology and the continuous expansion of the market, the performance and environmental performance of the PE tarpaulin coating device will be further improved.

[0003] For example, a Chinese patent (publication number: CN213920077U) discloses a PE tarpaulin coating device, which includes a woven cloth roll, a dust removal device arranged on the right side of the woven cloth roll for removing dust from the surface of the woven cloth, a double-sided laminating device arranged below the dust removal device, and a material receiving roll arranged below the double-sided laminating device. This utility model provides a double-sided dust removal device to vacuum both sides of the woven cloth to ensure that the surface of the woven cloth is dust-free. At the same time, a double-sided laminating device and a tension mechanism are provided to prevent the woven cloth from wrinkling due to excessive relaxation, and the woven cloth is double-sidedly laminated, which greatly speeds up the production speed and improves the product qualification rate, and has good application prospects.

[0004] The device is provided with components such as a spring, a rod sleeve, and a nut. By moving the nut downward along the adjusting rod, the tension of the tension mechanism can be changed, and the spring is used to ensure that the tension mechanism can automatically adapt to the tension of the woven cloth or waterproof membrane within a certain range. However, the tensioning effect of the device is not good. Since the spring will shake up and down, the coating may be uneven, thereby affecting the subsequent tarpaulin production. Therefore, a PE tarpaulin coating device is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a PE tarpaulin coating device, which has the advantage of good tensioning effect and solves the problem of poor tensioning effect.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a PE tarpaulin coating device, comprising a box body, a woven cloth roll rotatably connected between the front and rear side walls of the box body inner cavity, a tensioning mechanism capable of controlling the degree of tensioning provided on the rear inner wall of the box body, two reversing portions provided between the front and rear side walls of the box body inner cavity, two coating assemblies for coating provided in the inner cavity of the box body and at the bottom of the two reversing portions, a collecting roller for urging the cloth to move provided between the front and rear side walls of the box body, and a tarpaulin wrapped around the outer surface of the woven cloth roll;

[0007] The tensioning mechanism includes a servo motor, an active rod, a driving gear, a driven gear and a rotating part. The rear side wall of the box is fixed to the servo motor, the output shaft of the servo motor is fixed to the active rod, the outer surface of the active rod is fixed to the driving gear, the left side of the driving gear is engaged with the driven gear, and the front side of the driven gear is provided with a rotating part.

[0008] By adopting this technical solution, the tensioning mechanism can change the tensioning state of the tarpaulin at any time, further improving the coating effect.

[0009] Furthermore, the rotating part includes a stabilizing block, two connecting rods and a tensioning cylinder. The front of the driven gear is fixed to the stabilizing block, the front of the stabilizing block is fixed to the two connecting rods, and the outer surface of each connecting rod is fixed to the tensioning cylinder.

[0010] By adopting this technical solution, the tensioning state of the tarpaulin can be changed by rotating the tensioning cylinder, and the size of the stabilizing block is set between the driven gear and the connecting rod, which can reduce stress concentration during use.

[0011] Furthermore, two U-shaped holes are provided on the back of the box body, and the two U-shaped holes are adapted to the connecting rods.

[0012] By adopting this technical solution, the U-shaped hole is provided so that the connecting rod can pass through smoothly and rotate smoothly, further promoting smooth tensioning.

[0013] Furthermore, each of the reversing parts includes a support rod and a reversing cylinder. The front and rear side walls of the inner cavity of the box body are rotatably connected to the support rod through bearings, and the outer surface of each support rod is fixed to the reversing cylinder.

[0014] By adopting this technical solution, the use of the reversing part can prompt the tarpaulin to change direction, improve space utilization, and further reduce the volume of the box.

[0015] Furthermore, the tarpaulin includes a woven layer and a waterproof layer, and the upper and lower sides of the woven layer are fixed to the waterproof layer.

[0016] By adopting this technical solution, fixing the waterproof layer at both ends of the woven layer can improve the overall waterproofness of the tarpaulin.

[0017] Furthermore, a movable door is hinged on the front of the box, and an observation window is embedded in the movable door.

[0018] By adopting this technical solution, an observation window is set up to observe the internal progress at any time. After all the coating is completed, the movable door can be opened to take out the coated tarpaulin.

[0019] Furthermore, each of the coating components includes a waterproof film roll, a pressing roller and a glue sprayer. The waterproof film roll is rotatably connected to the front and rear inner walls of the box body, the pressing roller is rotatably connected to the front and rear side walls of the inner cavity of the box body, and the rear inner wall of the box body is fixed to the glue sprayer.

The driving motor is fixed to the inner wall of the box body, the output shaft of the driving motor is fixed to the rotating rod, and the outer surface of the rotating rod is fixed to the rotating cylinder.

[0022] By adopting this technical solution, the driving motor continuously outputs power, causing the rotating drum to rotate continuously, further causing the tarpaulin to move continuously.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The PE tarpaulin coating device has a woven layer wound on a woven cloth roll. The tarpaulin can be fully stretched by tensioning the tensioning mechanism, thereby ensuring the flatness of the tarpaulin surface. When processing different tarpaulins, the tensioning mechanism can be adjusted according to the specific situation to achieve different tensioning degrees, thereby ensuring the smooth progress of subsequent coating. When the woven layer passes through the coating assembly, the two pressing rollers will stick the waterproof layer to the woven layer, thereby achieving coating of the tarpaulin. After the coating is completed, the collecting roller is continuously tightened, and the coated tarpaulin is continuously wound and tightened. The device can freely adjust the tension, ensure the coating quality, improve the coating quality, and further improve the production efficiency of the tarpaulin. Since both ends of the woven layer are fixed to the waterproof layer, the waterproof performance of the tarpaulin can be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 3 In this embodiment, it includes a box body 1, a woven cloth roll 2 is rotatably connected between the front and rear side walls of the inner cavity of the box body 1, a tensioning mechanism 3 capable of controlling the degree of tension is provided on the rear inner wall of the box body 1, two reversing parts 4 are provided between the front and rear side walls of the inner cavity of the box body 1, two coating components 6 for coating are provided in the inner cavity of the box body 1 and at the bottom of the two reversing parts 4, a collecting roller 7 for promoting the movement of the cloth is provided between the front and rear side walls of the box body 1, and a tarpaulin 5 is wrapped around the outer surface of the woven cloth roll 2.

[0033] In addition, a movable door is hinged on the front of the box body 1, and an observation window is embedded in the movable door. The observation window can be set to facilitate observing the internal operating status at any time. When the tarpaulin 5 is completed with coating, the finished tarpaulin 5 can be removed by simply opening the movable door.

[0034] It should be further explained that the tensioning mechanism 3 includes a servo motor 301, an active rod 302, a driving gear 303, a driven gear 304 and a rotating part. The rear side wall of the box body 1 is fixed to the servo motor 301, the output shaft of the servo motor 301 is fixed to the active rod 302, the outer surface of the active rod 302 is fixed to the driving gear 303, the left side of the driving gear 303 is engaged with the driven gear 304, and the front face of the driven gear 304 is provided with a rotating part. The power is output by the servo motor 301 and transmitted by the driving gear 303 and the driven gear 304, further prompting the rotating part to rotate.

[0035] In addition, the rotating part includes a stabilizing block 305, two connecting rods 306 and a tensioning cylinder 307. The front of the driven gear 304 is fixed to the stabilizing block 305, and the front of the stabilizing block 305 is fixed to the two connecting rods 306. The outer surface of each connecting rod 306 is fixed to the tensioning cylinder 307. The size of the stabilizing block 305 is between the connecting rod 306 and the driven gear 304, which can reduce the concentration of gravity during operation.

[0036] It can be known that there are two U-shaped holes on the back of the box body 1, and the two U-shaped holes are adapted to the connecting rod 306. The connecting rod 306 can pass through the U-shaped holes and rotate in the U-shaped holes, thereby driving the tensioning cylinder 307 to rotate, further prompting the tensioning cylinder 307 to rotate.

[0037] In addition, each reversing part 4 includes a support rod 401 and a reversing cylinder 402. The front and rear side walls of the inner cavity of the box body 1 are rotatably connected to the support rod 401 through bearings. The outer surface of each support rod 401 is fixed to the reversing cylinder 402. The reversing part 4 can prompt the tarpaulin 5 to change direction smoothly, thereby improving the space utilization inside the box body 1 and further reducing the volume of the box body 1.

[0038] It should be noted that, by freely adjusting the tensioning mechanism 3, the tension of the tarpaulin 5 can be changed, and the coating effect can be guaranteed when coating different tarpaulins 5. The volume of the box 1 can be further reduced in conjunction with the reversing part 4 for easy storage.

[0039] Please refer again Figure 1 and Figures 4 to 5 In order to improve the waterproof performance of the tarpaulin, the tarpaulin 5 in this embodiment includes a woven layer 501 and a waterproof layer 502. The upper and lower sides of the woven layer 501 are fixed to the waterproof layer 502, and the two ends of the woven layer 501 are fixed to the waterproof layer 502, which can greatly improve the waterproof performance of the tarpaulin 5 and achieve double-layer waterproofing while achieving double-sided waterproofing.

[0040] It should be further explained that each coating component 6 includes a waterproof film roll 601, a pressing roller 602 and a glue sprayer 603. The waterproof film roll 601 is rotatably connected to the front and rear inner walls of the box body 1, and the pressing roller 602 is rotatably connected to the front and rear side walls of the inner cavity of the box body 1. The rear inner wall of the box body 1 is fixed to the glue sprayer 603. The provision of the pressing roller 602 can improve the pressing effect and further improve the fixing effect of the woven layer 501 and the waterproof layer 502. The provision of the glue sprayer 603 can further improve the operating efficiency of the device.

[0041] It can be known that the collecting roller 7 includes a driving motor, a rotating rod and a rotating drum. The driving motor is fixed to the inner wall of the box body 1, the output shaft of the driving motor is fixed to the rotating rod, and the outer surface of the rotating rod is fixed to the rotating drum. The driving motor outputs power to cause the rotating drum to rotate, and at the same time the rotating drum will continuously pull the tarpaulin 5, causing the tarpaulin 5 to continuously move.

[0042] In this embodiment, both ends of the woven layer 501 are fixed to the waterproof layer 502, which can greatly improve the waterproof effect of the tarpaulin 5. The firmness of the connection between the woven layer 501 and the waterproof layer 502 is further improved by pressing the roller 602, and finally the collecting roller 7 provides the tarpaulin 5 with the power to move.

[0043] It can be understood that the tensioning mechanism 3 can change the tension of the tarpaulin 5, thereby ensuring that any tarpaulin 5 can be in the optimal opening state, cooperating with the coating component 6 to improve the coating quality, and the waterproof layer 502 is coated on both sides of the woven layer 501, which can greatly improve the waterproof performance of the tarpaulin 5.

[0044] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0045] The working principle of the above embodiment is:

[0046] The braided layer 501 is wound around the outer surface of the braided cloth roll 2, and the other end of the braided layer 501 passes through the tensioning mechanism 3. When the tension needs to be changed, the servo motor 301 is started, and the power is transmitted from the active gear 303 on the active rod 302 to the driven gear 304, further prompting the stabilizing block 305 to rotate. The stabilizing block 305 will drive the two connecting rods 306 to rotate, and the two tensioning cylinders 307 will tighten the braided layer 501 during the rotation process to ensure that the braided layer 501 can be fully opened, thereby improving the coating effect. The braided layer 501 passes through the two reversing parts 4, prompting the braided layer 501 to change the rotation direction, thereby improving space utilization and reducing the lateral size of the box 1. The collection roller 7 is used to hold the braided layer 501 in place. The tarpaulin 5 is moved by a continuous rotation process. When the woven layer 501 passes through the pressing roller 602, the friction force causes the pressing roller 602 to rotate, continuously pulling down the waterproof layer 502 wrapped around the waterproof film roll 601. During the movement of the waterproof layer 502, the glue sprayer 603 continuously sprays glue. When the waterproof layer 502 contacts the woven layer 501, the glue is bonded to fix the woven layer 501 and the waterproof layer 502. The glue is then collected by the collecting roller 7. The device can freely adjust the tension to further improve the coating quality of the tarpaulin 5. Since both sides of the woven layer 501 are fixed to the waterproof layer 502, the tarpaulin 5 can have excellent waterproof performance.
