Description

Technical Field

[0001] The utility model relates to the field of conveyor belt production, in particular to a conveyor belt production unwinding device. Background Technique

[0002] PVC conveyor belt, fully known as polyvinyl chloride conveyor belt, has the characteristics of non-toxic, odorless, easy to clean, etc., and is especially suitable for the conveying, packaging and processing processes in the food industry, and can ensure the hygiene and safety of food.

[0003] The production process of PVC conveyor belt usually includes the following steps: raw material preparation, fabric treatment, mixing and coating, vulcanization treatment, cooling and shaping, unwinding and cutting, special processing, quality inspection, packaging and storage.

[0004] When the existing PVC conveyor belt is unwound, it is usually directly released from the surface of the unwinding roller. During production and observation, it is found that there are wrinkles on the surface of the PVC conveyor belt due to winding, processing, etc. When the PVC conveyor belt is unwound, the friction between the rubber in the wrinkled part and the roller will increase, which will cause wear on the surface of the PVC conveyor belt.

[0005] Therefore, an unwinding device for conveyor belt production is proposed for the above problems. Summary of the Utility Model

[0008] Preferably, a plurality of telescopic push rods are fixedly connected to the inner side wall of the pressing plate; a cross plate is fixedly connected to the bottom of the telescopic push rod; a runner is rotatably connected to the bottom of the cross plate; the runner will squeeze the elastic cloth and the conveyor belt under the action of gravity, enhancing the leveling effect of the device on the conveyor belt and improving the flatness of the surface of the conveyor belt during unwinding.

[0009] Preferably, a plurality of counterweights are fixedly connected to the top of the horizontal plate; the counterweights are located between the pressing plate and the elastic cloth; when the rotating wheel contacts the convex part of the conveyor belt surface, the rotating wheel will apply pressure to the telescopic push rod to make the telescopic push rod in a compressed state. At this time, due to the self-weight of the counterweights, the telescopic push rod will be subjected to an additional tensile force, ensuring that the telescopic push rod will be in a tensile state after the rotating wheel flattens the conveyor belt surface, increasing the contact time between the rotating wheel and the conveyor belt, and ensuring that the rotating wheel can stably flatten the conveyor belt.

[0010] Preferably, a plurality of sponges are fixedly connected to the bottom of the elastic cloth; the sponges are inclined; when the elastic cloth contacts the conveyor belt, the sponges will also contact the conveyor belt, and the sponges will clean the conveyor belt surface, reducing impurities such as dust and fibers remaining on the conveyor belt surface.

Subsequently, the spring telescopic rods will apply an elastic force to the second connecting plate and the roller, so that the roller will squeeze the conveyor belt, improving the surface tension of the conveyor belt during unrolling and ensuring that the surface of the conveyor belt can be in a taut state during unrolling.

[0012] Preferably, a trachea is communicated with the middle of one of the second connecting plates; the second connecting plate and the roller are in a communicating relationship; a plurality of round holes are opened in the middle of the roller; during operation, the trachea can be externally connected to an air pump, and the air pump will fill the second connecting plate and the roller with gas through the trachea.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 to 5 As shown, a conveyor belt production unwinding device according to an embodiment of the present invention includes a support base 1; a connecting frame 12 is fixedly connected to the top of the support base 1; a motor 17 is fixedly connected to the middle of the connecting frame 12; an output end of the motor 17 is fixedly connected to an unwinding roller 18; the unwinding roller 18 is rotatably connected to the connecting frame 12; a cylinder 13 is fixedly connected to the top of the connecting frame 12; an output end of the cylinder 13 is fixedly connected to a first connecting plate 14; a plurality of pressing plates 15 are disposed through and slidably connected to the middle of the first connecting plate 14; ends of the pressing plates 15 are correspondingly arranged with the unwinding roller 18; an elastic spring 16 is fixedly connected to an end of the pressing plate 15; both the elastic spring 16 and the first connecting plate 14 are in a fixedly connected relationship; an elastic cloth 19 is fixedly connected to an inner side wall of the pressing plate 15; starting the motor 17 can cause the unwinding roller 18 to rotate and unwind the conveyor belt. At the same time, starting the cylinder 13 causes the first connecting plate 14 to move towards the unwinding roller 18. When the first connecting plate 14 moves, it will drive the pressing plates 15 to move together. The pressing plates 15 will move towards the unwinding roller 18 together with the elastic cloth 19. When the elastic cloth 19 comes into contact with the unwinding roller 18, it will receive the pressure exerted by the conveyor belt on the surface of the unwinding roller 18. Subsequently, the elastic cloth 19 will transmit the pressure to the pressing plates 15 and the elastic springs 16. The pressing plates 15 will slide along the first connecting plate 14 and cause the elastic springs 16 to be in a stretched state. Subsequently, the elastic springs 16 will exert an elastic force on the pressing plates 15 and the elastic cloth 19, causing the elastic cloth 19 to squeeze the conveyor belt on the surface of the unwinding roller 18. The conveyor belt will rotate together with the unwinding roller 18. At this time, the conveyor belt will reduce the wrinkles on the surface under the squeezing action of the elastic cloth 19; the elastic cloth 19 will move together with the pressing plates 15 and squeeze the conveyor belt on the surface of the unwinding roller 18, realizing the leveling and flattening of the wrinkled area on the surface of the conveyor belt by the device, improving the flatness of the surface of the conveyor belt, and reducing the friction between the conveyor belt and other components.

[0027] Please refer to Figure 2 and Figure 3As shown, a plurality of telescopic push rods 2 are fixedly connected to the inner side wall of the pressing plate 15; a cross plate 22 is fixedly connected to the bottom of the telescopic push rod 2; a runner 23 is rotatably connected to the bottom of the cross plate 22; when the pressing plate 15 approaches the unwinding roller 18, the telescopic push rod 2 will also move together with the pressing plate 15, and the telescopic push rod 2 will move towards the unwinding roller 18 together with the cross plate 22 and the runner 23. When the elastic cloth 19 comes into contact with the conveyor belt on the surface of the unwinding roller 18, the runner 23 will also squeeze the conveyor belt through the elastic cloth 19, so that the conveyor belt will be subjected to an additional pressure; the runner 23 will squeeze the elastic cloth 19 and the conveyor belt under the action of gravity, enhancing the leveling effect of the device on the conveyor belt and improving the flatness of the surface of the conveyor belt during unwinding.

[0028] Please refer to Figure 3 As shown, a plurality of counterweight blocks 3 are fixedly connected to the top of the cross plate 22; the counterweight blocks 3 are located between the pressing plate 15 and the elastic cloth 19; when the runner 23 comes into contact with the convex part on the surface of the conveyor belt, the runner 23 will apply a pressure to the telescopic push rod 2 to make the telescopic push rod 2 in a compressed state. At this time, due to the own weight of the counterweight block 3, the telescopic push rod 2 will be subjected to an additional tensile force, ensuring that the telescopic push rod 2 will be in a stretched state after the runner 23 flattens the surface of the conveyor belt, increasing the contact time between the runner 23 and the conveyor belt, and ensuring that the runner 23 can stably press and level the conveyor belt.

[0029] Please refer to Figure 3 As shown, a plurality of sponges 4 are fixedly connected to the bottom of the elastic cloth 19; the sponges 4 are inclined; when the elastic cloth 19 comes into contact with the conveyor belt, the sponges 4 will also come into contact with the conveyor belt, and the sponges 4 will clean the surface of the conveyor belt, reducing impurities such as dust and fibers remaining on the surface of the conveyor belt. Because the sponges 4 are inclined, the frictional force between the sponges 4 and the conveyor belt is greater, enhancing the cleaning effect of the sponges 4 on the conveyor belt.

[0030] Please refer to Figure 1 and Figure 4 As shown, a pair of spring telescopic rods 5 are fixedly connected to the top of the support base 1; a second connecting plate 52 is fixedly connected to the top of the spring telescopic rod 5; a roller 53 is rotatably connected between the second connecting plates 52; after the conveyor belt is unwound, it will pass through the roller 53. The roller 53 will be subjected to the gravity of the conveyor belt and cause the spring telescopic rod 5 to be in a compressed state. Subsequently, the spring telescopic rod 5 will apply an elastic force to the second connecting plate 52 and the roller 53, so that the roller 53 will squeeze the conveyor belt, improving the surface tension of the conveyor belt during unwinding and ensuring that the surface of the conveyor belt can be in a taut state during unwinding.

[0031] Please refer to Figure 4 and Figure 5As shown, a trachea 6 communicates with the middle of one of the second connecting plates 52; the second connecting plate 52 and the roller 53 are in a communicating relationship; a plurality of round holes 62 are formed in the middle of the roller 53; during operation, the trachea 6 can be externally connected to an air pump, and the air pump will fill the second connecting plate 52 and the roller 53 with gas through the trachea 6. The air flow will spray out from the round holes 62 and reach the surface of the conveyor belt. The air flow will clean the other side of the conveyor belt, further reducing the impurities on the surface of the conveyor belt and improving the cleanliness of the conveyor belt surface.

[0032] Please refer to Figure 5 As shown, a plurality of elastic ropes 7 are fixedly connected to the inner side wall of the roller 53; the ends of adjacent elastic ropes 7 are fixedly connected with a guiding plate 72; the guiding plate 72 is of a horn-shaped structure; the guiding plate 72 and the round hole 62 are in sliding fit; when the conveyor belt passes through the roller 53, it will come into contact with the guiding plate 72. Because the guiding plate 72 is made of a flexible material, the guiding plate 72 will deform under the extrusion of the conveyor belt and enter the inside of the round hole 62, and the air flow ejected from the other round holes 62 will flow along the inner wall of the guiding plate 72, increasing the flow range of the air flow, expanding the contact area between the air flow and the conveyor belt, and enhancing the cleaning effect of the air flow on the conveyor belt.

[0033] Working principle: Starting the motor 17 can cause the unwinding roller 18 to rotate and unwind the conveyor belt. At the same time, starting the cylinder 13 causes the first connecting plate 14 to move towards the unwinding roller 18. When the first connecting plate 14 moves, it will drive the pressing plate 15 to move together. The pressing plate 15 will move closer to the unwinding roller 18 together with the elastic cloth 19. When the elastic cloth 19 comes into contact with the unwinding roller 18, it will be subjected to the pressure exerted by the conveyor belt on the surface of the unwinding roller 18. Subsequently, the elastic cloth 19 will transfer the pressure to the pressing plate 15 and the elastic spring 16. The pressing plate 15 will slide along the first connecting plate 14 and cause the elastic spring 16 to be in a stretched state. Then, the elastic spring 16 will exert an elastic force on the pressing plate 15 and the elastic cloth 19, causing the elastic cloth 19 to squeeze the conveyor belt on the surface of the unwinding roller 18. The conveyor belt will rotate together with the unwinding roller 18. At this time, the conveyor belt will reduce the wrinkles on its surface under the squeezing action of the elastic cloth 19; when the pressing plate 15 moves closer to the unwinding roller 18, the telescopic push rod 2 will also move together with the pressing plate 15. The telescopic push rod 2 will move towards the unwinding roller 18 together with the cross plate 22 and the runner 23. When the elastic cloth 19 comes into contact with the conveyor belt on the surface of the unwinding roller 18, the runner 23 will also squeeze the conveyor belt through the elastic cloth 19, causing the conveyor belt to be subjected to an additional pressure; when the runner 23 comes into contact with the convex part on the surface of the conveyor belt, the runner 23 will exert a pressure on the telescopic push rod 2, causing the telescopic push rod 2 to be in a compressed state. At this time, due to the self-weight of the counterweight 3, the telescopic push rod 2 will be subjected to an additional tensile force, ensuring that the telescopic push rod 2 will be in a stretched state after the runner 23 flattens the surface of the conveyor belt, increasing the contact time between the runner 23 and the conveyor belt; when the elastic cloth 19 comes into contact with the conveyor belt, the sponge 4 will also come into contact with the conveyor belt. The sponge 4 will clean the surface of the conveyor belt, reducing impurities such as dust and fibers remaining on the surface of the conveyor belt. Because the sponge 4 is inclined, the frictional force between the sponge 4 and the conveyor belt is greater; after the conveyor belt is unwound, it will pass through the roller 53. After the roller 53 is subjected to the gravity of the conveyor belt, the spring telescopic rod 5 will be in a compressed state. Subsequently, the spring telescopic rod 5 will exert an elastic force on the second connecting plate 52 and the roller 53, causing the roller 53 to squeeze the conveyor belt, improving the surface tension of the conveyor belt during unwinding; during operation, the air pipe 6 can be externally connected to an air pump. The air pump will fill the second connecting plate 52 and the roller 53 with gas through the air pipe 6. The air flow will spray out from the round holes 62 and reach the surface of the conveyor belt. The air flow will clean the other side of the conveyor belt, further reducing the impurities on the surface of the conveyor belt; when the conveyor belt passes through the roller 53, it will come into contact with the guiding plate 72. Because the guiding plate 72 is made of a flexible material, the guiding plate 72 will deform under the squeezing action of the conveyor belt and enter the interior of the round hole 62, and the air flow sprayed out from the remaining round holes 62 will flow along the inner wall of the guiding plate 72, increasing the flow range of the air flow.
