This device has a simple structure, convenient operation, simple manufacturing, low cost, and can automatically elastically compress the film, thereby not only eliminating the need for manual adjustment of the pressing force and saving adjustment time, but also ensuring that the pressing force on the film is always within a reasonable range, thereby improving production efficiency and ensuring product quality. However, this patent still has the following problems in actual use:

[0003] During the production process, existing plastic films will deviate, so a correction device is usually set up to correct the deviated plastic film. However, the movement of the correction roller is slow, so that after the deviated plastic film is corrected, the correction roller is still in a tilted state, so that the plastic film at this time will be guided to deviate, and then a signal is transmitted to the correction roller through the infrared detector, causing it to deviate to the other side and be corrected again. In this way, the plastic film is constantly in two states of left and right deviation and cannot be in a single correct position. In addition, in order to achieve the tension of the plastic film, the overall structure of the above-mentioned device is still relatively complex.

[0004] A conveying device for producing plastic films is proposed in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a conveying device for the production of plastic films, so as to solve the problem proposed in the above-mentioned background technology that an infrared detector transmits a signal to a correction roller to cause it to deflect to one side of the plastic film for correction. As a result, the plastic film is constantly in two states of left and right deviation and cannot be in a single correct position.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a conveying device for producing plastic film, comprising a conveyor, the conveyor comprising a conveyor frame, a receiving roller is installed on one side of the top of the conveyor frame, a steering roller is provided in the middle of the top of the conveyor frame, and the receiving roller and the steering roller are loaded with plastic film;

[0010] Preferably, the curved rack is slidably connected to the movable bin, the curved rack is fixedly connected to the top surface of the conveying rack, and the side of the curved groove is provided with a limit baffle fixedly connected to the conveying rack.

[0011] Preferably, the limit baffle is connected through a connecting rod, one end of the connecting rod is fixedly connected to a locking block, the locking block is locked and connected to the limit block, and both ends of the limit baffle can overlap with the side of the limit block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the conveying device for plastic film production allows the correcting roller to move quickly and accurately to the initial position, thereby preventing the correcting roller from misleading the corrected plastic film due to slow movement, thereby allowing the plastic film to be transported in the correct position, avoiding the plastic film from repeatedly changing between left and right deviations, and facilitating the processing of subsequent processes. The specific contents are as follows:

[0016] 1. The second motor is started to rotate the first gear, so that the mobile bin drives the correcting roller to move to the initial direction, and then the limit block squeezes the engaging block and engages with it, so that the second motor encounters a large resistance and stops rotating, and finally the correcting roller moves quickly to the initial position, so as to avoid the slow movement of the correcting roller causing it to mislead the already corrected plastic film to deviate, so that the plastic film can be transported in the correct position, avoiding the repeated changes in the left and right deviation of the plastic film, and facilitating the processing of subsequent processes.

Obviously, the implementation regulations 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.

[0025] See also Figure 1-5 The utility model provides a technical solution: a conveying device for the production of plastic film, comprising a conveyor 1, the conveyor 1 comprising a conveyor frame 101, a receiving roller 102 is installed on one side of the top of the conveyor frame 101, a steering roller 103 is provided in the middle of the top of the conveyor frame 101, and a plastic film 104 is carried on the receiving roller 102 and the steering roller 103;

[0026] A deviation correction component 2 is provided on one side of the steering roller 103. The deviation correction component 2 includes a motor compartment 201 rotatably connected to the inner side of the conveyor frame 101. A first motor 202 is fixedly connected to the interior of the motor compartment 201. The output end of the first motor 202 is fixedly connected to the deviation correction roller 203. The first motor 202 can make the deviation correction roller 203 rotate, thereby effectively correcting the deviation.

[0027] Among them, the other end of the correcting roller 203 is rotatably connected to the limit block 204, the bottom of the limit block 204 is fixedly connected to the mobile warehouse 205, and the bottom end of the mobile warehouse 205 is slidably connected to the curved groove 206; the curved groove 206 is opened on the surface of the conveying frame 101, and the interior of the mobile warehouse 205 is fixedly connected to the second motor 207, and the output end of the second motor 207 is fixedly connected to the first gear 208, and the first gear 208 is meshed with the curved rack 209; the curved groove 206 can guide the moving direction of the mobile warehouse 205.

[0028] The curved rack 209 is slidably connected to the mobile warehouse 205, and the curved rack 209 is fixedly connected to the top surface of the conveying frame 101. The side of the curved groove 206 is provided with a limit baffle 210 fixedly connected to the conveying frame 101; the limit baffle 210 is connected with a connecting rod 212, and one end of the connecting rod 212 is fixedly connected with a locking block 216, which is locked and connected to the limit block 204. The two ends of the limit baffle 210 can overlap with the side of the limit block 204; the limit baffle 210 and the curved groove 206 can both limit the moving end of the mobile warehouse 205. The locking block 216 cannot be directly disengaged after being engaged with the limit block 204. The limit block 204 is freed from the restriction only after the locking block 216 is pulled out.

[0029] A spring rod 211 is fixedly connected between the other end of the connecting rod 212 and the conveying frame 101, and an unlocking rack 213 is fixedly connected to the bottom surface of the connecting rod 212. The unlocking rack 213 is meshed with a second gear 214, and the second gear 214 is fixedly connected to a third motor 215. The third motor 215 is fixedly connected to the conveying frame 101; the unlocking rack 213 can drive the connecting rod 212 to drive the engaging block 216 to disengage from the engaging block 204 through the second gear 214.

[0030] The surface of the steering roller 103 overlaps the plastic film 104. Infrared detection devices fixed to the conveyor frame 101 are provided on both sides of the plastic film 104. The infrared detection devices are existing technologies and can detect whether the plastic film 104 is skewed.

[0031] A straightening mechanism 3 is provided below the middle of the conveyor frame 101. The straightening mechanism 3 comprises a rotating rod 301 rotatably connected to the vertical portion of the conveyor frame 101. The other end of the rotating rod 301 is rotatably connected to a rotating roller 302. The bottom of the rotating roller 302 overlaps the plastic film 104. The vertical position of the rotating roller 302 is located between the receiving roller 102 and the turning roller 103. By using the two simple parts of the rotating rod 301 and the rotating roller 302, the plastic film (104) can be kept taut in an extremely simple manner, thereby saving equipment costs.

[0032] Working principle: Before using this conveying device for plastic film production, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, first, when the infrared detection device detects that the plastic film 104 is offset, the third motor 215 is started to rotate the second gear 214, so that the unlocking rack 213 drives the connecting rod 212 to pull the engaging block 216 to move, thereby disengaging the engaging block 216 from the limiting block 204;

[0033] At the same time, the second motor 207 is started to rotate the first gear 208, and the movable chamber 205 slides along the curved groove 206 through the curved rack 209 until the limit block 204 moves to one end of the limit baffle 210 and is blocked by the limit baffle 210. At this time, the first motor 202 drives the correction roller 203 to rotate, thereby correcting the plastic film.

[0034] At this time, the third motor 215 cancels the control of the second gear 214 on the unlocking rack 213, so that the spring rod 211 pushes the connecting rod 212 to move to the original position;

[0035] When the deflection correction is completed, that is, the infrared detection device detects that the plastic film 104 has returned to the correct position, the second motor 207 is started to rotate the first gear 208, so that the movable chamber 205 drives the deflection correction roller 203 to move to the initial direction, and then the limit block 204 presses the engaging block 216 and engages with it, so that the second motor 207 encounters a large resistance and stops, and finally the deflection correction roller 203 is quickly moved to the initial position, so that the slow movement of the deflection correction roller 203 does not mislead the corrected plastic film 104 to deflect, so that the plastic film 104 can be transported in the correct position, which is convenient for subsequent processing.

[0036] During this process, the weight of the rotating roller 302 will press the rotating rod 301 to rotate downward, so that the plastic film 104 can remain taut. If there is too much plastic film 104 required in subsequent processes, it will be pulled by the rotating roller 302 to cause the rotating rod 301 to rotate upward, thereby keeping the plastic film 104 still taut.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
