Description

Technical Field

[0001] The invention relates to the technical field of tarpaulin film production, in particular to an ultraviolet protection calendering tarpaulin film production device. Background Art

[0002] Tarpaulin film is a composite material that combines the durability of a tarpaulin with the properties of a film material. It is usually used for outdoor covering, protection, waterproofing and sun protection. It has the strength of a tarpaulin and the lightness of a film. It is widely used in agriculture, construction, transportation, industry and outdoor activities. During production, a tarpaulin film requires a production device to calender and connect the tarpaulin and the UV protection film together.

[0003] For example, a coating machine for tarpaulin production with publication number 202410363967.X includes an equipment base, three groups of rotating brackets are fixedly connected to the equipment base, and the three groups of rotating brackets are respectively rotatably connected to a front axle, a middle axle and a rear axle, and the front axle, the middle axle and the rear axle are connected by a conveyor belt transmission. The present invention can synchronously drive the auxiliary conveying roller to rotate in the opposite direction during the tarpaulin conveying process to achieve extrusion-type conveying of the tarpaulin. At the same time, the roller can rotate to clean the surface of the tarpaulin to ensure the coating processing effect of the tarpaulin, and can ensure the synchronization of tarpaulin conveying and film unwinding, so that the film pressing roller can fully press the film to the surface of the tarpaulin, thereby ensuring the integrity of the tarpaulin and the film. The degree of body fit can be improved, and the tarpaulin with coating can be automatically and quickly cooled, which is beneficial to improving the overall processing efficiency of batch tarpaulin coating; although the above application has many beneficial effects, it still has the following shortcomings: the position of the pressure roller is adjusted by a compression spring. This design performs well in terms of operational convenience. However, after a period of use, the elastic performance of the spring will decay, which will undoubtedly have an adverse effect on the compaction effect of the pressure roller and increase the capital investment of the device. In addition, the power source of the fan blade is connected to the conveying roller. Since the conveying roller rotates relatively slowly in the process of conveying the tarpaulin film, it is difficult for the fan blade to generate strong wind force, and thus it is impossible to effectively cool the tarpaulin film after calendering. Summary of the invention

[0004] Aiming at the problem in the prior art that the hot pressing roller becomes unstable due to the attenuation of the spring performance, the present invention provides a production device for ultraviolet protection calendered tarpaulin film.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a UV protection calendered tarpaulin film production device comprises a frame, three overlapping rollers are rotatably connected to the frame, a mounting frame is fixedly connected to the top of the frame, a hot pressing roller is slidably connected to the mounting frame, and a guiding mechanism is provided on the frame; A position control mechanism for controlling the position of the hot pressing roller is provided on the mounting frame. The position control mechanism includes a first motor, a first magnet, and a second magnet. The first motor is fixedly installed on the outer wall of the mounting frame. The first magnet is rotatably connected to the mounting frame. The second magnet is fixedly connected to the top end of the hot pressing roller. A temperature control mechanism for adjusting the temperature of the tarpaulin film is provided at the top end of the frame. The temperature control mechanism includes two support seats and a circulating water pump. A water tank is fixedly connected between the support seats. An inlet is fixedly connected to the top end of the water tank. A drain pipe is fixedly connected to the bottom end of the water tank. An opening and closing valve is provided on the drain pipe. The top output end of the circulating water pump is fixedly connected to a water suction pipe. The bottom output end of the circulating water pump is fixedly connected to a delivery pipe. A connecting pipe is fixedly connected to the bottom end of the water tank.

[0006] Specifically, the top end of the first magnet is set as the south pole, the bottom end of the first magnet is set as the north pole, the top end of the second magnet is set as the north pole, and the output end of the first motor is fixedly connected to one of the axles of the first magnet.

[0007] Specifically, the guiding mechanism includes a second motor, a temperature adjusting roller, and a conveying roller. Symmetrically arranged connecting pipes are fixedly connected to the temperature adjusting roller. Transmission gears are fixedly connected to both the connecting pipes and the axles of the conveying rollers.

[0008] Specifically, the second motor is fixedly installed on the outer wall of the frame. The connecting pipes are all rotatably connected to the frame. The conveying roller is rotatably connected to the frame at a position corresponding to the bottom end of the connecting pipe. The output end of the second motor is fixedly connected to one of the axles of the conveying roller. The transmission gears are meshed with each other.

[0009] Specifically, the support seats are all fixedly connected to the top end of the frame. One end of the drain pipe and the connecting pipe both penetrate through one of the support seats. One end of the connecting pipe is rotatably connected to one of the connecting pipes. A sealing ring is provided at the connection between the connecting pipe and the connecting pipe. One end of the water suction pipe penetrates through the other support seat and is fixedly connected to the water tank. One end of the delivery pipe penetrates through the outer wall of the frame and is rotatably connected to the other connecting pipe. A sealing ring is provided at the connection between the delivery pipe and the connecting pipe.

[0010] Specifically, symmetrically arranged support legs are fixedly connected to the bottom end of the frame, and there are four support legs in total.

[0011] The beneficial effects of the present invention: (1)When it is necessary to adjust the position of the hot press roller, the operator only needs to start the first motor and flexibly adjust the angle of the first magnet with the help of this motor. At this time, the first magnet and the second magnet will form a state of repulsion between the two poles, and the strong repulsive force generated between them can skillfully control the position of the hot press roller. The repulsive force formed between the first magnet and the second magnet has excellent stability and will not decay due to the prolongation of the use time. This not only significantly reduces the additional resources required due to the decline of equipment performance, but also helps the hot press roller to always maintain accurate position control during long-term use, providing a strong guarantee for the stability of the production process and the product quality.

[0012] (2)By skillfully using the circulating water pump, the cooling water can be made to circulate smoothly inside the temperature control roller. As the cooling water continuously circulates, the temperature of the temperature control roller can be effectively reduced. When the tarpaulin film is conveyed through the temperature control roller, the temperature control roller, with its lower temperature, can fully absorb the heat carried by the tarpaulin film, thereby achieving a good effect of cooling the tarpaulin film.

Detailed Embodiments

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 5 , the present invention provides the following technical solutions: Example 1: The production device of the ultraviolet protection calendered tarpaulin film includes a frame 1, on which three overlapping rollers 2 are rotatably connected. A mounting frame 3 is fixedly connected to the top of the frame 1, and a hot pressing roller 4 is slidably connected to the mounting frame 3. A guiding mechanism 5 is provided on the frame 1; The guiding mechanism 5 includes a second motor 51, a temperature adjusting roller 52 and a conveying roller 53. Symmetrically arranged connecting pipes 54 are fixedly connected to the temperature adjusting roller 52. Transmission gears 55 are fixedly connected to both the connecting pipes 54 and the shafts of the conveying roller 53. The second motor 51 is fixedly installed on the outer wall of the frame 1. The connecting pipes 54 are rotatably connected to the frame 1. The conveying roller 53 is rotatably connected to the frame 1 at a position corresponding to the bottom end of the connecting pipe 54. The output end of the second motor 51 is fixedly connected to one of the shafts of the conveying roller 53. The transmission gears 55 are meshed with each other. Symmetrically arranged support legs 8 are fixedly connected to the bottom end of the frame 1. There are four support legs 8 in total; During use, the tarpaulin is lapped on the top of the overlapping roller 2 at the bottom of the side, and then the tarpaulin is passed through between the overlapping roller 2 and the hot pressing roller 4 in the middle position, and then through between the conveying roller 53 and the temperature adjusting roller 52 and connected to an external winding roller. The ultraviolet protection film is lapped on the bottom of the overlapping roller 2 at the top of the side, and then the operation of the tarpaulin is repeated. At this time, the corresponding positions of the two with respect to the hot pressing roller 4 and the middle overlapping roller 2 are rolled together by the hot pressing roller 4. At this time, the external winding roller can be started, and at the same time, the second motor 51 is also started. The second motor 51 will drive the conveying roller 53 to rotate. The rotation of the conveying roller 53 will drive the transmission gear 55 to rotate. The transmission gear 55 will drive the top transmission gear 55 to rotate. The top transmission gear 55 will drive the connecting pipe 54 and the temperature adjusting roller 52 to rotate. The operation of the guiding mechanism 5 can cooperate with the external winding roller to wind and pull the tarpaulin and the ultraviolet protection film. At this time, the hot pressing roller 4 will cooperate with the overlapping roller 2 in the middle position to hot press the moving tarpaulin and the ultraviolet protection film, so that the tarpaulin and the ultraviolet protection film are combined to complete the processing of the tarpaulin film.

[0018] Example 2: The technical solution of this example different from that of Example 1 includes: A position control mechanism 6 for controlling the position of the hot pressing roller 4 is provided on the mounting frame 3. The position control mechanism 6 includes a first motor 61, a first magnet 62 and a second magnet 63. The first motor 61 is fixedly installed on the outer wall of the mounting frame 3. The first magnet 62 is rotatably connected to the mounting frame 3. The second magnet 63 is fixedly connected to the top of the hot pressing roller 4. The top of the first magnet 62 is set as the south pole, and the bottom of the first magnet 62 is set as the north pole. The top of the second magnet 63 is set as the north pole. The output end of the first motor 61 is fixedly connected to one of the shafts of the first magnet 62; During use, when the bottom end of the hot pressing roller 4 needs to be pressed against the top end of the intermediate lapping roller 2, the first motor 61 can be started. The first motor 61 will drive the first magnet 62 to rotate, so that the north pole surface of the first magnet 62 corresponds to the north pole surface of the second magnet 63. At this time, a strong repulsive force will be generated between the two due to the same poles. The position of the first magnet 62 remains unchanged, while the second magnet 63 will drive the hot pressing roller 4 to slide downward on the mounting bracket 3. The sliding hot pressing roller 4 will tightly press against the top end of the lapping roller 2 in the middle position. When the hot pressing roller 4 needs to be adjusted upward, just make the south pole surface of the first magnet 62 correspond to the north pole surface of the second magnet 63. At this time, a strong magnetic attraction force will be generated between the second magnet 63 and the first magnet 62, and the second magnet 63 will slide upward on the mounting bracket 3. The repulsive force formed between the first magnet 62 and the second magnet 63 has excellent stability and will not decay due to the extension of the use time. This not only significantly reduces the additional resources required due to the decline of equipment performance, but also helps the hot pressing roller 4 to always maintain precise position control during long-term use, providing a strong guarantee for the stability of the production process and the product quality.

[0019] It further includes: a temperature adjusting mechanism 7 for adjusting the temperature of the tarpaulin film is provided at the top end of the frame 1. The temperature adjusting mechanism 7 includes two support seats 71 and a circulating water pump 72. A water tank 73 is fixedly connected between the support seats 71. An inlet 74 is fixedly connected to the top end of the water tank 73. A drain pipe 75 is fixedly connected to the bottom end of the water tank 73. An opening and closing valve 76 is provided on the drain pipe 75. The top output end of the circulating water pump 72 is fixedly connected with a water suction pipe 77. The bottom output end of the circulating water pump 72 is fixedly connected with a delivery pipe 78. A connecting pipe 79 is fixedly connected to the bottom end of the water tank 73. The support seats 71 are both fixedly connected to the top end of the frame 1. One end of the drain pipe 75 and one end of the connecting pipe 79 both penetrate through one of the support seats 71. One end of the connecting pipe 79 is rotatably connected to one of the connecting pipes 54. A sealing ring is provided at the connection between the connecting pipe 79 and the connecting pipe 54. One end of the water suction pipe 77 penetrates through the other support seat 71 and is fixedly connected to the water tank 73. One end of the delivery pipe 78 penetrates through the outer wall of the frame 1 and is rotatably connected to the other connecting pipe 54. A sealing ring is provided at the connection between the delivery pipe 78 and the connecting pipe 54; In use, an appropriate amount of cooling water can be added into the interior of the water tank 73 through the water inlet 74, and then the circulating water pump 72 is started. The start of the circulating water pump 72 will pump out the water inside the water tank 73 through the suction pipe 77, and then convey the cooling water to the interior of the connecting pipe 54 and the temperature regulating roller 52 through the conveying pipe 78. Then, the cooling water will be conveyed to the interior of the communicating pipe 79 through another connecting pipe 54, and finally return to the interior of the water tank 73 through the communicating pipe 79. The start of the circulating water pump 72 will cause the above operations to be repeated. At this time, the rotating temperature regulating roller 52 will always maintain a relatively low temperature due to the continuous circulation of the cooling water. When the temperature regulating roller 52 rotates, it will cool the tarpaulin film being conveyed, and can fully absorb the heat carried by the tarpaulin film, thereby achieving a good effect of cooling the tarpaulin film. When the temperature regulating roller 52 rotates, the connecting pipe 54 will also rotate. Sealing rings are provided at the joints of the conveying pipe 78 and the communicating pipe 79 with the connecting pipe 54 to prevent water leakage during the cooling process. When it is necessary to replace the cooling water inside the water tank 73, the opening and closing valve 76 can be rotated, and then the drain pipe 75 will drain the cooling water inside the water tank 73.
