Description

Technical Field

[0002] With the continuous advancement of science and technology and the continuous improvement of people's living standards, cars have gradually entered thousands of households. During car sales test drives and when cars are driven in some relatively dirty environments (such as construction sites, gravel plants, etc.), people will put a layer of plastic film protective cover on the outside of the car seats to prevent the car seats from getting dirty. This can effectively protect the car seats in a short time. The production of plastic film protective covers for car seats requires multiple processes such as cutting, picking, feeding, and bonding elastic bands of plastic films, among which conveying and deviation correction are relatively important links.

[0003] In the process of conveying plastic film, as the plastic film is continuously wound, the original slight deviation will continue to expand with the increase in the number of winding turns, eventually causing wrinkles and deviations to appear inside the plastic film roll, and the entire roll will also be relatively tilted, affecting subsequent transportation and processing. The existing correcting mechanism does not tighten the film during the correction process, which makes it easy for wrinkles and overlaps to appear during the correction process. Some correcting mechanisms only adjust and move a certain point of the plastic film during the correction process, resulting in a large change in force at that position, which is prone to tearing and affects product quality.

DETAILED DESCRIPTION

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 9 The figure shows a conveying and correcting device for a plastic film protective cover of a car seat, comprising a base 1, a conveying mechanism, a correcting mechanism and a beating mechanism. A workbench 2 is fixedly connected to the base 1, and the conveying mechanism is installed on the base 1 for conveying the plastic film 36 of the protective cover. The correcting mechanism comprises two sets of correcting shafts 3 rotatably connected to the workbench 2 respectively, and a guide groove 4 is provided in the correcting shaft 3. A guide rod 5 is fixedly connected in the guide groove 4. Two sets of correcting spirals 6 with opposite spiral directions are fixedly connected to the outer wall of the guide rod 5, which is used to drive the correcting shaft 3 to rotate so that the correcting spirals 6 and the inner wall of the plastic film 36 generate friction, stretch the plastic film 36 to both sides, and ensure the relative flatness of the plastic film 36 during the conveying process. The beating mechanism comprises beating plates 7 installed on both sides of the base 1, which are used to link the beating plates 7 on both sides to intermittently beat back and forth at both ends of the plastic film 36 when the conveying mechanism is running, so as to align the plastic film 36 in the center and avoid deviation during the winding and conveying process.

[0020] The correcting mechanism also includes a threaded rod 8 which is coaxially rotatably connected to the correcting shaft 3. The threaded rod 8 passes through the guide rod 5 and is threadedly connected to the guide rod 5. The conveying mechanism is used to link the correcting shafts 3 on both sides to rotate during operation. Two sets of connecting plates 9 are slidably connected to the workbench 2 in the horizontal direction. The outer walls at both ends of the guide rod 5 are respectively fixedly connected with connecting rings 10 which are rotatably connected to the connecting plates 9 on both sides. The workbench 2 is provided with an adjusting part for synchronously driving the threaded rods 8 on both sides to rotate and adjust.

[0021] The conveying mechanism includes two groups of mounting frames 11 fixedly mounted on the base 1, and the two groups of mounting frames 11 are rotatably connected with output rollers 12 and winding rollers 13 respectively. A first motor 14 is fixedly connected to the base 1, and the output end of the first motor 14 is coaxially fixedly connected with a driving shaft 15, and the driving shaft 15 is coaxially fixedly connected to one end of the winding roller 13. The outer wall of the driving shaft 15 is connected to the outer wall of the correcting shaft 3 close to the first motor 14 through a pulley transmission, and a third belt 34 is connected between the two groups of correcting shafts 3 through a pulley transmission.

[0022] The adjusting part includes a second motor 27 fixedly mounted on the workbench 2. The models of the first motor 14 and the second motor 27 are preferably YYHS-40. Both ends of the threaded rod 8 are coaxially fixedly connected with a driven wheel 28. The output end of the second motor 27 is coaxially fixedly connected with a driving rod 29. Two groups of driving wheels 30 are coaxially fixedly connected to the driving rod 29. The outer wall of the driving wheel 30 is transmission-connected with a first belt 32 that is transmission-connected to the two groups of driven wheels 28 on the same side close to the second motor 27.

[0023] In this embodiment, after the plastic film 36 wrapped around the output roller 12 is guided by two groups of deflection correction shafts 3, one end is driven and reeled by the winding roller 13. The middle position of the plastic film 36 passes horizontally through the upper side of the workbench 2. The upper side of the workbench 2 can perform operations such as cutting, dust removal, and marking on the plastic film 36. The first motor 14 is started to drive the drive shaft 15 to rotate, so that the winding roller 13 can transport and reel the plastic film 36, and the drive shaft 15 will drive the second belt 33 to make the adjacent deflection correction shafts 3 rotate synchronously, thereby driving the third belt 34 to rotate another group of deflection correction shafts 3.

[0024] During the process of conveying the plastic film 36 from the output roller 12 to the winding roller 13, the outer wall of the correcting spiral 6 contacts and rubs against the bottom surface of the plastic film 36. The correcting spiral 6 is symmetrically arranged in two groups, which can tighten the plastic film 36 to both sides during the friction with the bottom surface of the plastic film 36, thereby improving the flatness of the plastic film 36 during transportation and avoiding wrinkles, overlaps, etc. of the plastic film 36 during the correction process.

[0025] When it is necessary to push the plastic film 36 to one side for correction, the second motor 27 is started to drive the driving wheel 30 to rotate through the driving rod 29, and the driving wheel 30 drives the driven wheels 28 on both sides to rotate through the first belt 32, and the driven wheels 28 drive the threaded rod 8 to rotate, so that the rotation speed of the threaded rod 8 is different from the rotation speed of the correction shaft 3. The rotation direction of the driving rod 29 is adjusted so that when the threaded rod 8 and the correction shaft 3 rotate in the same direction, the rotation speed of the threaded rod 8 is greater than the correction shaft 3, so that the threaded rod 8 drives the guide rod 5 to slide horizontally to the left in the guide groove 4, which can drive the correction spiral 6 to move to the left as a whole. The synchronous adjustment of the correction shafts 3 on both sides is ensured by the connecting plate 9, so that the plastic film 36 between the two sets of correction shafts 3 can be adjusted to the left as a whole. Compared with the single-point adjustment and correction of the traditional correction device, this overall correction method for a certain length is more stable, and avoids the situation where the plastic film 36 is unevenly stressed during the single-point adjustment process and is torn.

[0026] On the contrary, when it is necessary to adjust and correct the deviation to the right, the threaded rod 8 and the correcting shaft 3 are controlled to rotate in opposite directions, so that the threaded rod 8 can drive the guide rod 5 to slide to the right in the guide groove 4, drive the correcting screw 6 to move to the right as a whole, and move the plastic film 36 between the two sets of correcting shafts 3 as a whole to the right by a set distance to complete the correcting operation.

[0027] It is worth noting that: when the correction operation is not needed, the second motor 27 stops running, and the driving wheel 30 and the driven wheel 28 can rotate arbitrarily. At this time, the correction shaft 3 will drive the guide rod 5 and the threaded rod 8 to rotate synchronously during the rotation process. There is no relative rotation between the guide rod 5 and the threaded rod 8, which can ensure the stability of the position of the guide rod 5. At this time, only the correction screw 6 on the guide rod 5 rotates to realize the tensioning function.

[0028] During the conveying process, the flapping plates 7 on both sides are linked by the flapping mechanism to intermittently flap back and forth at both ends of the plastic film 36, so as to center the plastic film 36 and avoid deviation during winding and conveying. The device has a high degree of automation and is convenient and efficient to operate.

[0029] Example 2: Please refer to Figure 2-Figure 6 , this embodiment further illustrates the first embodiment, the slapping mechanism shown in the figure also includes a buffer spring 16 fixedly mounted on the side of the slapping plate 7, the end of the buffer spring 16 away from the slapping plate 7 is fixedly connected to the driving plate 17, and multiple sets of sliding rods 35 are fixedly connected to the side of the slapping plate 7, the sliding rods 35 penetrate the driving plate 17, and are slidably connected to the driving plate 17 in the horizontal direction, and a sliding block 18 is fixedly connected to the driving plate 17 and is slidably connected to the mounting frame 11 in the horizontal direction, the output roller 12 and the winding roller 13 penetrate the slapping plates 7 and the driving plates 17 on both sides, and are movably sleeved with the inner walls of the slapping plates 7 and the driving plates 17, a pressure sensor is provided at one end of the buffer spring 16, and a driving member is provided on the output roller 12 for linkage control of the driving plate 17 to slide back and forth during rotation.

[0030] The driving member includes a driving box 19 fixedly installed on both sides of the workbench 2, a pushing plate 20 is slidably connected in the driving box 19, a connecting rod 21 rotatably connected to the side of the pushing plate 20 at a non-center position on the side of the output roller 12, an output pipe 22 is connected to the side of the driving box 19, a control rod 23 is fixedly connected to the side of the sliding block 18, a plurality of control pipes 25 connected to the output pipe 22 are fixedly connected to the workbench 2, and the outer wall of the control rod 23 is slidably connected to the inner wall of the control pipe 25.

[0031] In this embodiment, during the rotation of the output roller 12, the connecting rods 21 at both ends will be driven to rotate, so that the push plate 20 performs reciprocating piston motion in the drive box 19. The drive box 19 is used to store hydraulic oil. As the push plate 20 slides back and forth, the hydraulic strength in the drive box 19 is increased or decreased. When the hydraulic strength increases, the pressure can be output to one end of the control rod 23 through the output pipe 22 and the control pipe 25, pushing the control rod 23 to slide, so that the sliding blocks 18 on both sides slide in the mounting frame 11, driving the drive plate 17 to move toward the two sides of the plastic film 36. The drive plate 17 pushes the buffer spring 16, and guides the flapping plate 7 through the sliding rod 35, so that the side of the flapping plate 7 hits the two sides of the plastic film 36, and is buffered by the buffer spring 16 to avoid excessive squeezing of the plastic film 36.

[0032] On the contrary, when the hydraulic strength in the drive box 19 decreases, the hydraulic pressure in the control tube 25 decreases, and the control rod 23 can be pulled into the control tube 25, driving the drive plates 17 on both sides to open synchronously to both sides, and the flapping plate 7 is away from the plastic film 36. In this way, the purpose of intermittent flapping of the two ends of the plastic film 36 can be achieved. On the one hand, the plastic film 36 can be vibrated back to the center position, and on the other hand, the offset state of the plastic film 36 can be monitored, which is convenient for subsequent correction and adjustment. Since multiple groups of control tubes 25 are connected to the output tube 22, the drive plates 17 on both sides are subjected to the same force during the sliding process. Rollers can be provided on the side of the sliding block 18 to reduce the friction between the mounting frame 11. The movement state of the flapping plates 7 on both sides needs to be monitored regularly to avoid inconsistent moving distances.

[0033] By comparing the readings of the pressure sensors on the buffer springs 16 on both sides, when the readings are consistent, it means that the thrusts on both ends of the plastic film 36 are the same during the beating and extrusion process, and the plastic film 36 is in a relatively centered position, and there is no need to start the second motor 27 for correction adjustment. When the readings on both sides are inconsistent, it means that the plastic film 36 is offset toward the side with a larger reading, and the second motor 27 can be controlled to move the correction screw 6 to the side with a smaller reading to complete the correction function.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
