DETAILED DESCRIPTION

[0022] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples. Example

[0023] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 8 , this application provides an automatic color steel plate packaging device, please refer to Figure 1 and Figure 2 , including a conveying mechanism 1, a color steel plate main body 600 is placed on the top of the conveying mechanism 1, a winding roller 3 is fixedly connected to the back of the conveying mechanism 1, a packing belt 700 is wound around the outer side of the winding roller 3, and a bundling component 2 is arranged in the middle of the conveying mechanism 1. The conveying mechanism 1 conveys the color steel plate main body 600 to be bundled to the inner side of the bundling component 2, and the bundling component 2 drives the packing belt 700 to be spirally wound around the outer side of the color steel plate main body 600 for multiple turns.

[0024] Specifically, since a single batch of color steel plate main bodies 600 are stacked in multiple pieces, in order to ensure their stability, the number of bundling times needs to be set according to their specific length. The color steel plate main bodies 600 are placed on the top of the conveying mechanism 1 and the motor group 103 drives the conveying rollers 104 to rotate to advance the color steel plate main bodies 600. When the position to be bundled is pushed to the inside of the bundling component 2, the motor group 103 is stopped. After a single bundling work is completed, the motor group 103 is started to continue conveying the color steel plate main bodies 600 to the next bundling position and move to the inside of the bundling component 2.

[0025] Please refer to Figure 2 The conveying mechanism 1 includes two motor groups 103. The output shaft of the motor group 103 is connected to a conveying roller 104. The front and back sides of the conveying roller 104 are rotatably connected to a bracket 101. The motor group 103 drives the conveying roller 104 to move and convey the color steel plate body 600. A guide plate 102 is provided on the top of the bracket 101 on one side to guide the color steel plate body 600.

[0026] Specifically, when conveying the color steel plate body 600, the bracket 101 located on one side is the unloading end, and the bracket 101 located on the other side is the loading end. The bracket 101 located on the other side first starts to convey the color steel plate body 600 through the inner side of the bundling component 2 to the top of the bracket 101 located on one side, and stops the motor group 103 after reaching the first bundling position. When the position of the color steel plate body 600 passing through the bundling component 2 exceeds half of the length of the color steel plate body 600, the two motor groups 103 are started at the same time when the color steel plate body 600 is conveyed again, thereby improving the stability of conveying; when the position of the color steel plate body 600 passing through the bundling component 2 far exceeds half of the length of the color steel plate body 600, only the motor group 103 located on one side is started when the color steel plate body 600 is conveyed again, thereby saving conveying costs.

[0027] Please refer to Figure 3 , Figure 6 , Figure 7 The bundling assembly 2 includes a bundling track 201, both ends of which are fixedly connected with covers 202, the inner side of the bundling track 201 is connected with a spiral rack 203, and a bundling traction assembly 204 is provided on the side of the bundling track 201 away from the spiral rack 203. The spiral rack 203 cooperates with the bundling traction assembly 204 to drive the strapping belt 700 to make a spiral motion around the color steel plate body 600.

[0028] Please refer to Figure 6 , Figure 7The bundling track 201 includes a track body 2011, which is a hollow structure. A side slide groove 2012 is provided on one side of the track body 2011, and a movable slide groove 2013 is provided on the side of the track body 2011 close to the conveying mechanism 1. A spiral rack 203 is fixedly connected to the inner wall of the track body 2011 on the side away from the movable slide groove 2013, and the teeth of the spiral rack 203 are distributed close to the side of the movable slide groove 2013.

[0029] Please refer to Figure 8 The bundling traction assembly 204 includes a gear 2041, the teeth of the gear 2041 are meshed with the teeth of the spiral rack 203, a driving motor 2042 is fixedly connected to one side of the gear 2041, the output shaft of the driving motor 2042 is fixedly connected to the gear 2041, a protective box is sleeved on the outer side of the driving motor 2042, a convex block 2043 is fixedly connected to one side of the protective box of the driving motor 2042, a mounting frame 2044 is fixedly connected to the side of the driving motor 2042 close to the moving slide groove 2013, a clamping hand 2045 is fixedly connected to the side of the mounting frame 2044 close to the moving slide groove 2013, a square groove 2046 is provided on the side of the clamping hand 2045 close to the conveying mechanism 1, and a first clamping plate 2047 is provided on the inner side of the square groove 2046.

[0030] Specifically, the drive motor 2042 is started, so that the drive motor 2042 drives the gear 2041 to rotate, and the teeth of the gear 2041 mesh with the teeth of the spiral rack 203, so that the gear 2041 moves along the distribution route of the spiral rack 203, driving the packing belt 700 to perform a spiral winding movement around the color steel plate main body 600; a convex rod is rotatably provided on the other side of the gear 2041, and a convex groove that matches the gap with the convex rod is provided on the side of the track main body 2011 away from the side slide groove 2012, and when the gear 2041 meshes and performs a spiral movement around the spiral rack 203, the convex block 2043 moves synchronously in a spiral motion along the side slide groove 2012, and the convex rod moves synchronously in a spiral motion along the convex groove.

[0031] Please refer to Figure 1 , Figure 4 , Figure 5 The other side of the bracket 101 on one side is connected to a second guide assembly 5, and the second guide assembly 5 includes a guide block 501. The front of the guide block 501 is provided with a guide hole for the strapping belt 700, and the inner side of the guide hole of the guide block 501 is connected to a third clamping plate 502.

[0032] Specifically, the workshop worker first passes the open end of the rolled strapping tape 700 through the guide hole of the guide block 501, and then inserts the open end of the strapping tape 700 into the square groove 2046 to fix the strapping tape 700.

[0033] Please refer to Figure 5The third clamping plate 502 includes two clamping block bodies 5021, and square holes 5022 are opened on adjacent sides of the two clamping block bodies 5021. The top of the clamping block body 5021 located at the top is fixedly connected with an electric push rod 5023, and the output shaft of the electric push rod 5023 is fixedly connected to the top of the clamping block body 5021 located at the top.

[0034] Specifically, when the bundling traction assembly 204 moves to the position where the spiral rack 203 is closest to the motor group 103, the control system pauses the driving motor 2042. At this time, the electric push rod 5023 is started to push the clamping block body 5021 at the top to move downward, so that the gap between the clamping block bodies 5021 is reduced, and the clamping block bodies 5021 clamp the strapping belt 700 at the discharge end to stop the strapping belt 700 from discharging. Then the driving motor 2042 is started again to start moving. At this time, the driving motor 2042 drives the strapping belt 700 to move to tighten the strapping belt 700 that has been wrapped around the outside of the color steel plate body 600.

[0035] Please refer to Figure 5 A cutting knife 503 is slidably connected to the inner side of the third clamping plate 502 at the bottom, and an electric push rod 504 is fixedly connected to the bottom of the cutting knife 503. The length and width of the electric push rod 504 are both matched with the length and width of the square hole 5022, and the output shaft of the electric push rod 504 is fixedly connected to the bottom of the cutting knife 503.

[0036] Specifically, in the initial state, the cutting knife 503 is completely immersed in the square hole 5022 at the bottom, and the reduction in the distance between the two clamping block bodies 5021 is caused by the height decrease of the clamping block body 5021 at the top. The square hole 5022 at the bottom is always located on the outside of the cutting knife 503 until the electric push rod 504 drives the cutting knife 503 to move up. When the electric push rod 504 drives the cutting knife 503 to move up, the cutting knife 503 can cut the packing tape 700. In order to ensure a more thorough cutting, the output shaft of the electric push rod 504 will drive the cutting knife 503 to move down to the square hole 5022 at the top.

[0037] Please refer to Figure 1 , Figure 3 One side of the bracket 101 located on the other side is connected to the first guide component 4, the first guide component 4 includes a hydraulic cylinder 401, one side of the hydraulic cylinder 401 is slidably connected to a hydraulic rod 402, one side of the hydraulic rod 402 is fixedly connected to a U-shaped seat 403, and a second clamping plate 404 is provided on the inner side of the top of the U-shaped seat 403.

[0038] Specifically, before moving to the very end, since the U-shaped seat 403 is arranged on the front side of the tail end of the strapping track 201 and the opening direction of the movable slide slot 2013 is always toward the spiral inner side of the strapping track 201, when passing through the U-shaped seat 403, the strapping belt 700 will be pulled by the first clamping plate 2047 and stuck into the top of the U-shaped seat 403 and between the second clamping plate 404 until the first clamping plate 2047 drives the strapping belt 700 to move to the very end of the spiral rack 203, and then the driving motor 2042 is turned off, and then the second clamping plate 404 is started first to reduce the gap between the second clamping plates 404, and then the first clamping plate 2047 is started to expand the gap between the first clamping plates 2047, and at this time the first clamping plate 2047 is loosened. The strapping tape 700 is fixed by the second clamping plate 404, and the second clamping plate 404 clamps the strapping tape 700. The hydraulic cylinder 401 is started to make the hydraulic rod 402 extend outward to push the second clamping plate 404 to move in the direction of the second guide assembly 5, so that the position of the strapping tape 700 fixed by the second clamping plate 404 is close to the position of the strapping tape 700 fixed by the clamping block body 5021. After they are close, the workshop worker uses an external binding machine to fix the two adjacent strapping tapes 700 through a lock, and then starts the electric push rod 504 to drive the cutting knife 503 to move up to the inside of the square hole 5022 to cut off the position of the strapping tape 700 fixed by the clamping block body 5021. After cutting, the second clamping plate 404 is started to loosen the strapping tape 700, and a bundling work is completed.

[0039] Please refer to Figure 3 , Figure 5 , Figure 8 The structure of the second clamping plate 404 and the structure of the first clamping plate 2047 are the same as the internal structure of the third clamping plate 502 .

[0040] Specifically, starting the second clamping plate 404 causes one side of the second clamping plate 404 to move away from or closer to the other side, thereby expanding or reducing the gap between the second clamping plates 404; starting the first clamping plate 2047 causes the top of the first clamping plate 2047 to move away from or closer to the bottom, thereby expanding or reducing the gap between the first clamping plates 2047.

[0041] How it works When the color steel plate is packed, the workshop worker first passes the open end of the rolled packing tape 700 through the guide hole of the guide block 501, and then inserts it into the inner side of the square groove 2046. In the initial state, the square groove 2046 is at the head end of the spiral rack 203. Figure 6 As shown, the distance between the first clamping plates 2047 and the distance between the second clamping plates 404 are both greater than the thickness of the strapping tape 700, and the U-shaped seat 403 is located at the front of the rear end of the strapping track 201; The first clamping plate 2047 is started to reduce the gap between the first clamping plates 2047 to stably clamp one end of the strapping belt 700, and then the driving motor 2042 is started, so that the driving motor 2042 drives the gear 2041 to rotate, and the teeth of the gear 2041 are meshed with the teeth of the spiral rack 203, so that the gear 2041 moves along the distribution route of the spiral rack 203, driving the strapping belt 700 to make a spiral winding movement around the color steel plate body 600. When the strapping traction component 204 moves to the position where the spiral rack 203 is closest to the motor group 103, the control system pauses the driving motor 2042, and the electric push rod 502 is started at this time. 3 pushes the clamping block body 5021 at the top to move downward, so that the gap between the clamping block bodies 5021 is reduced, and the clamping block body 5021 clamps the packing belt 700 at the discharge end to stop the packing belt 700 from discharging, and then continues to start the driving motor 2042 to start moving. At this time, the driving motor 2042 drives the packing belt 700 to move and tighten the packing belt 700 that has been wound around the outer side of the color steel plate body 600, and drives the gear 2041 to move to the rear end of the spiral rack 203. Before moving to the rear end, since the U-shaped seat 403 is arranged on the front side of the rear end of the strapping track 201 and the moving slide slot 2013 opens toward When the strapping belt 700 is pulled toward the inner side of the spiral of the strapping track 201 and passes through the U-shaped seat 403, the strapping belt 700 is stuck between the top of the U-shaped seat 403 and the second clamping plate 404 under the traction of the first clamping plate 2047, until the first clamping plate 2047 drives the strapping belt 700 to move to the tail end of the spiral rack 203, and then the driving motor 2042 is turned off, and then the second clamping plate 404 is started first to reduce the gap between the second clamping plates 404, and then the first clamping plate 2047 is started to expand the gap between the first clamping plates 2047. At this time, the first clamping plate 2047 releases the strapping belt 700 and the second clamping plate 404 clamps the strapping belt 700, and the strapping belt 700 is started. The hydraulic cylinder 401 extends the hydraulic rod 402 outward to push the second clamping plate 404 to move toward the second guide assembly 5, so that the position of the strapping tape 700 fixed by the second clamping plate 404 is close to the position of the strapping tape 700 fixed by the clamping block body 5021. After the strapping tape 700 is close to each other, the workshop worker uses an external binding machine to fix the two strapping tapes 700 close to each other through a lock buckle, and then starts the electric push rod 504 to drive the cutting knife 503 to move up to the inside of the square hole 5022 to cut off the strapping tape 700 fixed by the clamping block body 5021. After cutting, the second clamping plate 404 is started to loosen the strapping tape 700, and a binding work is completed at this time. Since a single batch of color steel plate main bodies 600 are stacked in multiple pieces, in order to ensure their stability, the number of bundling times needs to be set according to their specific length. The color steel plate main bodies 600 are placed on the top of the conveying mechanism 1 and the motor group 103 drives the conveying roller 104 to rotate to advance the color steel plate main bodies 600. When the position to be bundled is pushed to the inside of the bundling component 2, the motor group 103 is stopped. After a single bundling work is completed, the motor group 103 is started to continue conveying the color steel plate main bodies 600 to the next bundling position and move to the inside of the bundling component 2.

[0042] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
