[0038] ReferenceFigures 1 to 5 The utility model discloses a kind of wrapping paper winding forming devices shown in an embodiment, comprising: rack 100, paper tape roll 200, fixed plate 300, paper pressing and cutting mechanism 400, feeding mechanical arm 500, translation rotation mechanism 700.Paper tape roll 200 is rotatably installed on rack 100, and paper tape roll 200 is used to store wrapping paper 210;Wrapping paper 210 is strip, and wrapping paper 210 is wound on paper tape roll 200.Wrapping paper 210 is self-adhesive, and the specific structure and installation mode of paper tape roll 200 are prior art, so it is not described in detail again.Fixed plate 300 is horizontally adjustable position and is located on rack 100.Wrapping paper 210 extends from paper tape roll 200 to the upper end of fixed plate 300, and the side of fixed plate 300 is rotatably installed with redirection roller, to reduce the size of the horizontal direction of the whole equipment, paper tape roll 200 is usually arranged at different height with fixed plate 300, so redirection roller is arranged, so that wrapping paper 210 passes through redirection roller, changes the movement direction of wrapping paper 210, so that wrapping paper 210 can extend horizontally to the upper end of fixed plate 300.The upper end of fixed plate 300 is smooth plane to reduce the friction force when wrapping paper 210 moves on the upper end of fixed plate 300, and the side without adhesive on wrapping paper 210 contacts with the upper end of fixed plate 300, and first driving part 110 for driving fixed plate 300 to move horizontally is connected on rack 100;First driving part 110 selects electric push rod or pneumatic push rod, and paper pressing and cutting mechanism 400 is arranged on rack 100 and can be adjusted in position up and down, and rack 100 is connected with second driving part 120 for driving paper pressing and cutting mechanism 400 to ascend and descend, and second driving part 120 selects electric push rod or pneumatic push rod.Paper pressing and cutting mechanism 400 can fix and cut wrapping paper 210 located on the upper end of fixed plate 300 when descending;Since multiple workpieces 600 need to be continuously processed, wrapping paper 210 needs to be cut before processing next workpiece 600.Feeding mechanical arm 500 is connected with rack 100, and feeding mechanical arm 500 has at least three degrees of freedom of movement in specific direction, and the specific structure and installation mode of feeding mechanical arm 500 are prior art, and feeding mechanical arm 500 clamps workpiece 600 from last process, and feeding mechanical arm 500 is used to transport workpiece 600 to winding position, and then releases workpiece 600.Workpiece 600 located in winding position contacts with wrapping paper 210 on the upper end of fixed plate 300;Translation rotation mechanism 700 is used to drive workpiece 600 on the upper end of fixed plate 300 to rotate and move along the axis of workpiece 600.Workpiece 600 contacts with the side with adhesive of wrapping paper 210 when being placed in winding position, workpiece 600 winds wrapping paper 210 when rotating, and workpiece 600 moves axially to make wrapping paper 210 evenly wound on workpiece 600.

[0039] Reference Figures 1 to 5As shown, the translation rotation mechanism 700 is provided below with an ejection belt, when the translation rotation mechanism 700 moves to the position that the workpiece 600 is completely separated from the paper pressing and cutting mechanism 400, the translation rotation mechanism 700 releases the workpiece 600, so that the workpiece 600 falls on the ejection belt, and then the ejection belt transports the workpiece 600 to the next process.

[0040] Referring to Figures 1 to 5 As shown, it can be understood that the angle between the movement direction of the fixed plate 300 and the extension direction of the workpiece 600 at the winding position is 30 to 60 degrees. The smaller the angle between the movement direction of the fixed plate 300 and the extension direction of the workpiece 600 at the winding position, the more wrapping paper 210 will be wound on the workpiece 600, and the larger the angle between the movement direction of the fixed plate 300 and the extension direction of the workpiece 600 at the winding position, the more wrapping paper 210 will be wound on the workpiece 600, so the angle between the movement direction of the fixed plate 300 and the extension direction of the workpiece 600 at the winding position is selected to be 30 to 60 degrees, which can save wrapping paper 210 as much as possible under the premise of meeting the packaging strength requirement.

[0041] Referring to Figures 1 to 5 As shown, it can be understood that the fixed plate 300 is provided with a protrusion 310, and the protrusion 310 abuts against the side of the workpiece 600 away from the paper tape roll 200 at the winding position. The protrusion 310 plays a limiting role on the workpiece 600 when the workpiece 600 rotates, preventing the workpiece 600 from shaking and causing uneven winding of the wrapping paper 210.

[0042] Referring to Figures 1 to 5 As shown, it can be understood that the paper pressing and cutting mechanism 400 includes a mounting plate 410, a cutter 420 and a first paper pressing block 430, the mounting plate 410 is aligned with the fixed plate 300 in the vertical direction, and the mounting plate 410 is aligned with the workpiece 600 at the winding position in the vertical direction. The mounting plate 410 is connected with the second driving part 120, and the second driving part 120 can drive the mounting plate 410 to ascend and descend. The cutter 420 and the first paper pressing block 430 are both bolted to the lower end of the mounting plate 410, the cutter 420 is located between the first paper pressing block 430 and the protrusion 310, and the cutter 420 can descend to cut off the wrapping paper 210 at the upper end of the fixed plate 300, and the first paper pressing block 430 can descend to abut against the wrapping paper 210 at the upper end of the fixed plate 300. After the cutter 420 cuts off the wrapping paper 210, the part of the wrapping paper 210 close to the paper tape roll 200 is fixed by the first paper pressing block 430, and the part of the wrapping paper 210 close to the workpiece 600 is continuously wound by the workpiece 600.

[0043] Referring to Figures 1 to 5As shown, it can be understood that the lower end of the mounting plate 410 is also provided with a limiting block 411, which is aligned with the workpiece 600 in the winding position in the vertical direction, and is aligned with the wrapping paper 210 in the vertical direction. The limiting block 411 is used to limit the up and down shaking of the workpiece 600 in the winding position. The limiting block 411 cooperates with the protrusion 310 to limit the workpiece 600 when the workpiece 600 rotates, preventing the workpiece 600 from shaking and causing the wrapping paper 210 to be unevenly wound.

[0044] Referring to Figures 1 to 5 As shown, it can be understood that the fixed plate 300 can be adjusted in position up and down, and is provided with a second paper pressing block 320, which is located on the side of the first paper pressing block 430 away from the cutter 420. The fixed plate 300 is connected with a third driving part 330 for driving the second paper pressing block 320 to rise and fall, and the second paper pressing block 320 can be lowered to tightly abut the wrapping paper 210 at the upper end of the fixed plate 300. After processing a workpiece 600, the fixed plate 300 needs to be moved so that the wrapping paper 210 can move below the workpiece 600 in the winding position. During this movement, the first paper pressing block 430 is separated from the fixed plate 300, and the second paper pressing block 320 cooperates with the fixed plate 300 to fix the wrapping paper 210, so that the wrapping paper 210 can move with the fixed plate 300.

[0045] Referring to Figures 1 to 5 As shown, it can be understood that the translation and rotation mechanism 700 includes a clamping jaw 710 and a bracket 720, and the clamping jaw 710 is selected from a pneumatic finger or an electric clamp. The bracket 720 is horizontally adjustable and is arranged on the rack 100. The rack 100 is horizontally connected with a linear guide rail, and the bracket 720 is slidingly connected to the rack 100 through the linear guide rail. The rack 100 is provided with a fourth driving part 130, which is selected from a combination of a pneumatic push rod or an electric motor and a synchronous belt. The fourth driving part 130 is used to drive the bracket 720 to move horizontally. The clamping jaw 710 is rotatably installed on the bracket 720, and the bracket 720 is provided with a fifth driving part 721 for driving the clamping jaw 710 to rotate. When multiple clamping jaws 710 are provided, the same fifth driving part 721 can be used for driving. The fifth driving part 721 is selected from a combination of a stepping motor and a synchronous belt, which has the advantage of being able to synchronously drive multiple clamping jaws 710 to rotate. The structure for driving the clamping jaw 710 to move and rotate is simple and low in cost.

[0046] Referring to Figures 1 to 5As shown, it can be understood that the rotating shaft 722 is rotatably installed on the support 720, and when the clamping jaw 710 is selected as the pneumatic finger, the center of the rotating shaft 722 should be provided with an air flow hole and connected with the compressed air pipeline through the external rotating joint. The clamping jaw 710 obtains the compressed air through the air flow hole. In this way, the clamping jaw 710 can rotate without causing the compressed air pipeline to be wound and knotted. The clamping jaw 710 is slidably installed on the end of the rotating shaft 722 through the linear guide rail, and the clamping jaw 710 can move along the radial direction of the rotating shaft 722. The support 720 is connected with the sixth driving part 723, which is selected as the pneumatic push rod or the electric push rod. The sixth driving part 723 is located above the clamping jaw 710, and the sixth driving part 723 is used to push the clamping jaw 710 to move downward. When the rotating shaft 722 rotates to the direction in which the clamping jaw 710 moves and the pushing direction of the sixth driving part 723 coincide, the extension end of the sixth driving part 723 can be lowered and push the clamping jaw 710 to move downward.

[0047] Referring to Figures 1 to 5 As shown, it can be understood that the elastic member 724 is connected between the rotating shaft 722 and the clamping jaw 710, and the elastic member 724 is used to drive the central axes of the rotating shaft 722 and the clamping jaw 710 to be aligned. Since the extension end of the sixth driving part 723 can only drive the clamping jaw 710 to move downward, when the extension end of the sixth driving part 723 is retracted, the elastic member 724 drives the central axes of the rotating shaft 722 and the clamping jaw 710 to be aligned through the elastic force of the elastic member 724. In this way, when the clamping jaw 710 clamps the workpiece 600, the rotation center of the workpiece 600 coincides with the rotating shaft 722. The elastic member 724 is selected as the spring or the rubber band.

[0048] Referring to Figures 1 to 5 As shown, it can be understood that the rotating shaft 722, the clamping jaw 710, the paper tape roll 200, the fixing plate 300, the feeding mechanical arm 500 and the paper pressing and cutting mechanism 400 are provided in multiple groups to simultaneously process multiple workpieces 600, thereby effectively improving the processing efficiency.

[0051] Step two, the sixth driving part 723 extends, pushes the clamping jaw 710 to move downwards, the clamping jaw 710 opens, then the fourth driving part 130 drives the support 720 to move horizontally, makes the clamping jaw 710 move to be aligned with the end of the workpiece 600 in the vertical direction, then the sixth driving part 723 extends and retracts, the elastic member 724 drives the clamping jaw 710 to move upwards to be aligned with the workpiece 600 in the horizontal direction, the clamping jaw 710 closes and clamps the workpiece 600;

[0052] Step three, the fifth driving part 721 drives the clamping jaw 710 to rotate, the fourth driving part 130 drives the clamping jaw 710 to move away from the fixed plate 300, and the wrapping paper 210 is uniformly wound on the workpiece 600;

[0053] Step four, the third driving part 330 drives the second paper pressing block 320 to descend to abut against the wrapping paper 210 on the upper end of the fixed plate 300, the second driving part 120 drives the mounting plate 410 to descend, the cutter 420 cuts the wrapping paper 210, the second driving part 120 drives the mounting plate 410 to ascend, the fifth driving part 721 continues to drive the clamping jaw 710 to rotate, and the fourth driving part 130 continues to drive the clamping jaw 710 to move away from the fixed plate 300;

[0054] Step five, after the workpiece 600 completely separates from the fixed plate 300, the clamping jaw 710 is released, and the workpiece 600 falls onto the discharge belt;
