Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of knife net processing, and particularly relates to a floating tensioned knife net rolling device. Background Art
[0002] The blade net is a protective net for the cutting tool. For example, in shaving products, the blade net contacts the skin and the hair is guided into the blade net, and then the hair is cut by the movement of the cutting tool. Therefore, the smoothness of the front and back of the blade net must reach the required precision, otherwise it will cause the blade net to scratch the skin or cause the cutting tool to stop. At the same time, the thickness of the blade net is about 1mm. The general grinding process includes unwinding, grinding, and winding. However, for winding, there are generally the following technical defects:
[0003] 1) The stress applied to the knife net during grinding is unstable, which causes the tension of the rolled knife net to be inconsistent. Therefore, the resulting rolling will increase the deformation rate of the knife net. At the same time, excessive pulling will lead to insufficient grinding or tearing.
[0004] 2) The knife roll formed always maintains a loose outward force, and the force is uneven, which directly affects the stability of the subsequent process and increases the NG rate of the product caused by the knife net. Utility Model Content
[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved floating tensioned knife net retracting device.
[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0007] A floating tensioned knife net winding device includes a receiving roller group and a winding assembly, wherein the winding assembly includes a winding disk and a drive, the receiving roller group includes a roller seat, a front receiving roller and a rear receiving roller, a transmission roller located between the front receiving roller and the rear receiving roller, and a follower pressure roller that maintains downward elastic pressure and presses positively on the transmission roller, wherein the front receiving roller guides the knife net to the winding disk, and the rear receiving roller is used to connect the knife net to be wound; there are multiple transmission rollers arranged side by side, and the follower pressure roller corresponds to the transmission roller one by one. The knife net winding device also includes a power device, which drives multiple or any one transmission roller to rotate, and the corresponding follower pressure rollers keep rotating in opposite directions to push the knife net forward.
[0008] Preferably, the front guide roller and the rear guide roller are both free-rotating rollers. By freely rotating, sliding friction is converted into rolling friction, which is more conducive to the forward push of the knife net.
[0009] According to a specific embodiment and preferred aspect of the present invention, both the front guide roller and the rear guide roller press the blade net downward from the bottom. The resulting downward pressure tension keeps the blade net in horizontal transmission, thereby improving the stability of the winding tension.
[0010] Preferably, the bottom surfaces of the front and rear guide rollers are flush with the top surface of the transmission roller, so as to keep the knife net transmitted horizontally.
[0011] According to another specific embodiment and preferred aspect of the present invention, guide rails extending vertically are provided on roller seats at both ends of each roller. The blade net retracting device further includes a downward pressure assembly, wherein the downward pressure assembly includes an upper seat and a lower seat slidably mounted on the guide rails, an elastic member positioned between the upper and lower seats, and a locking bolt that maintains contact with the upper seat. Under the interference of the locking bolt, the elastic member remains compressed and provides downward elastic pressure. The follower pressure roller is mounted between the two lower seats from the axial end. The downward pressure is adjusted based on the resistance provided by the locking bolt, so that the blade net is pushed forward under the most appropriate tension.
[0012] Preferably, there are two transmission rollers, two corresponding guide rails, two corresponding pressing assemblies, and two corresponding follower pressure rollers, which are respectively pressed directly above the transmission rollers based on the pressing assemblies.
[0013] Furthermore, the top surfaces of the two transmission rollers, the bottom surface of the front receiving roller, and the bottom surface of the rear receiving roller are flush; the bottom surfaces of the two follower pressure rollers are flush and pressed above the moving knife net.
[0014] In some embodiments, the power unit is a drive motor, and the two transmission rollers are connected to the drive motor from their ends, and the two transmission rollers rotate in the same direction. Based on the same direction of transmission, it is more conducive to keeping the blade net in a horizontal state and pushing it forward.
[0015] Preferably, a power gear is installed at the shaft end of the driving motor, and two transmission gears meshing with the same power gear are installed at the shaft ends of the two transmission rollers, and the two transmission gears rotate in the same direction to push the knife net forward to keep it clamped and move forward horizontally.
[0016] In addition, sleeves are formed at both ends of the front and rear lead rollers. The roller surface between the sleeves forms the conveying surface. The conveying surfaces of the front and rear lead rollers, the top of the transfer roller, and the bottom of the follower pressure roller form a horizontally extending conveying channel. This conveying channel limits horizontal conveying, and the sleeves form a widthwise constraint, maintaining a consistent reeling position and improving reeling uniformity.
[0017] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:
[0018] In the existing knife net rolling process, the stress applied to the knife net by grinding is unstable, resulting in the inability to maintain the same tension in the rolled knife net. Therefore, the resulting rolling will increase the deformation rate of the knife net, and at the same time, it will cause insufficient grinding or tearing due to excessive pulling. In addition, the formed knife roll always maintains a loose outward force, and the force is uneven, which directly affects the stable progress of the subsequent process and increases the NG rate of the product caused by the knife net. The present application comprehensively designs the structure of the floating tensioned knife net rolling device, cleverly solving the shortcomings and defects of the existing technology, and adopts the floating tensioned knife net rolling device. After the tensioned knife net is wound up, the front and rear guide rollers are used to guide the blade net, and the transmission roller and the floating downward pressure follower pressure roller rotate in opposite directions to keep the blade net horizontal and move forward in a tensioned state to complete the winding of the blade net with constant tension. Therefore, compared with the existing technology, the present invention realizes the constant tension winding of the winding disk based on the cooperation between the front and rear guide rollers, the transmission roller and the follower pressure roller. On the other hand, the transmission roller and the follower pressure roller form an opposite movement to implement forward pushing assistance, which greatly improves the winding quality, reduces the deformation rate, and also reduces the NG rate of the blade net and blade head assembly products caused by winding up.

[0030] like Figures 1 to 4 As shown, the floating tensioned knife net winding device of this embodiment includes a receiving roller group 1 and a winding assembly 2, wherein the receiving roller group 1 includes a roller seat 10, a front receiving roller 11 and a rear receiving roller 12, a transmission roller 13 located between the front receiving roller 11 and the rear receiving roller 12, and a follower pressure roller 14 that maintains downward elastic pressure and presses positively on the transmission roller 13; the winding assembly 2 includes a winding disk 20 and a drive 21.
[0031] In some embodiments, the front guide roller 11 guides the blade net M toward the winding reel 20, while the rear guide roller 12 receives the blade net M to be wound. Both the front guide roller 11 and the rear guide roller 12 are freely rotating rollers. This free rotation converts sliding friction into rolling friction, further facilitating the forward propulsion of the blade net. Both the front guide roller 11 and the rear guide roller 12 press the blade net M downward from below. This downward pressure maintains horizontal transport of the blade net, improving winding tension stability. The bottom surfaces of the front and rear guide rollers 11 and 12 are flush with the top surface of the transfer roller 13, maintaining horizontal transport of the blade net.
[0032] There are multiple transmission rollers 13 arranged side by side, and the follower pressure rollers 14 correspond to the transmission rollers 13 one by one. The roller seats 10 at both ends of each roller are respectively provided with guide rails 15 extending up and down. The knife net rewinding device also includes a downward pressure component 3 and a power device 4. The downward pressure component 3 includes an upper seat 30 and a lower seat 31 slidably mounted on the guide rails 15, an elastic member 32 located between the upper seat 30 and the lower seat 31, and a locking bolt 33 that maintains resistance against the upper seat. Under the resistance of the locking bolt 33, the elastic member 32 remains compressed and provides downward elastic pressure. The follower pressure roller 14 is installed between the two lower seats 32 from the shaft end. The magnitude of the downward pressure is adjusted based on the resistance force provided by the locking bolt 33, so that the knife net is pushed forward under the most appropriate tension; the power device 4 drives multiple or any one of the transmission rollers 13 to rotate, and the corresponding follower pressure roller 14 keeps rotating in the opposite direction to push the knife net M forward.
[0033] In this example, there are two transport rollers 13, two corresponding sets of guide rails 15, two corresponding sets of down-holding assemblies 3, and two corresponding follower pressure rollers 14, each of which is pressed directly above the transport rollers 13 based on the down-holding assemblies 3. The top surfaces of the two transport rollers 13, the bottom surfaces of the front guide roller 11, and the bottom surfaces of the rear guide roller 12 are flush; the bottom surfaces of the two follower pressure rollers 14 are flush and pressed above the moving knife net M.
[0034] In some embodiments, the power unit 4 is a drive motor, and the two transfer rollers 13 are connected to the drive motor from their ends. The two transfer rollers 13 rotate in the same direction. This same-direction transmission facilitates the forward propulsion of the blade net while maintaining a horizontal position. A power gear 5 is mounted on the shaft end of the drive motor. Two transmission gears 6 mesh with the same power gear 5 at the shaft ends of the two transfer rollers 13. The two transmission gears 6 rotate in the same direction, propelling the blade net M forward, maintaining a horizontal position.
[0035] In addition, roller sleeves 7 are formed at both ends of the front and rear guide rollers 11 and 12. The roller surface between the two roller sleeves 7 constitutes the rolling surface. The rolling surfaces of the front and rear guide rollers 11 and 12, the top of the transfer roller 13, and the bottom of the follower pressure roller 14 form a horizontally extending rolling channel. The rolling channel limits the horizontal transmission, and the roller sleeves form a widthwise restriction, maintaining the same position during winding, improving winding uniformity.
[0036] The winding reel 20 is composed of a conventional reel and a disc, wherein the reel is kept parallel to each roller; the drive 21 is a conventional motor and is installed on the roller seat 10.
[0037] In summary, the implementation process of this embodiment is as follows:
[0038] The knife net M is pressed down and pushed forward by the guidance of the rear guide roller 12. At the same time, the transmission roller 3 and the floating and elastic downward-pressing follower pressure roller 14 rotate in opposite directions to keep the knife net M horizontal and move forward in a tensioned state. The two groups of transmission rollers 3 and the follower pressure roller 14 move in the same direction to clamp and push forward, and the knife net is guided to the winding disk 20 by the front guide roller 11 for winding.
[0039] Therefore, compared with the prior art, the present invention realizes constant tension winding of the winding disk based on the cooperation between the front and rear guide rollers, the transmission roller and the follow-up pressure roller on the one hand; on the other hand, the transmission roller and the follow-up pressure roller form a relative motion to implement forward pushing assistance, which greatly improves the winding quality, reduces the deformation rate and also reduces the NG rate of the knife net and knife head assembly products caused by winding; the front guide roller and the rear guide roller are both free-rotating rollers, that is, the sliding friction is converted into rolling friction through free rotation, which is more conducive to the forward pushing of the knife net; the fourth aspect is that the front guide roller and the rear guide roller both press the knife net downward from the bottom, and the downward pressure tension formed keeps the knife net transmitted horizontally to improve the stability of the winding tension, and at the same time, the bottom surface of the front guide roller and the rear guide roller are flush with the top surface of the transmission roller to keep the knife net transmitted horizontally; the fourth aspect is based on the change of the resistance force provided by the locking bolt to adjust the size of the downward force, so that it pushes the knife net forward under the most appropriate tension; On the fifth aspect, there are two transmission rollers, two corresponding groups of guide rails, two corresponding groups of down-pressing components, and two corresponding follow-up pressure rollers, which are pressed directly above the transmission rollers based on the down-pressing components. The top surfaces of the two transmission rollers, the bottom surfaces of the front guide rollers, and the bottom surfaces of the rear guide rollers are flush; the bottom surfaces of the two follow-up pressure rollers are flush and pressed above the moving knife net; the power device is a driving motor, and the two transmission rollers are connected to the driving motor from the end, and the two transmission rollers rotate in the same direction. Based on the same-direction transmission, it is more conducive to keeping the knife net in a horizontal state and pushing it forward; on the fifth aspect, a power gear is installed at the shaft end of the driving motor, and two transmission gears meshing with the same power gear correspond to the shaft ends of the two transmission rollers, and the two transmission gears keep rotating in the same direction to push the knife net forward to keep it clamped horizontally and move forward; on the sixth aspect, based on the roller pressure channel limitation, horizontal transmission is maintained, and the roller sleeve forms a width direction limitation to keep winding in the same position and improve the neatness of winding.
