Technical Field

[0001] The utility model relates to the technical field of PET cutting, in particular to a thin yarn PET cutting device with an auxiliary limiting mechanism. Background Technique

[0002] PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. And PET is made into a thin yarn structure to form a thin yarn PET material. During the production process of the thin yarn PET material, a cutting device is often required to cut the thin yarn PET material. However, the existing thin yarn PET cutting devices have some deficiencies, such as:

[0003] A multifunctional PET film cutting and processing device with the application number CN202322533514.0 can automatically trim the edges of the PET film by this device, the operation is relatively convenient, and both sides of the PET film are relatively neat after cutting, improving the production quality of the PET film. The cutting assembly cuts the PET film, which is convenient for unloading the PET film, and the cutting is relatively accurate. However, in the actual use process, it is difficult to fix and limit the thin yarn PET workpiece, which may cause the position of the thin yarn PET workpiece to shift during the cutting process of the device, resulting in the failure of cutting.

[0004] Therefore, we propose a thin yarn PET cutting device with an auxiliary limiting mechanism to solve the problems raised above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a thin yarn PET cutting device with an auxiliary limiting mechanism to solve the problem that most thin yarn PET cutting devices in the current market are difficult to fix and limit the thin yarn PET workpiece, which may cause the position of the thin yarn PET workpiece to shift during the cutting process of the device, resulting in the failure of cutting as mentioned in the above background technique.

[0008] By driving the first drive shaft or the second drive shaft to rotate respectively through the drive motor, it is possible to make the drive motor drive the first drive shaft and the transmission mechanism to operate when rotating forward, while driving the second drive shaft and the cutting mechanism to operate when the drive motor rotates reversely, thereby increasing the controllability of the device.

A reciprocating threaded shaft 25 is connected to the bottom of the worm gear 24, and a threaded sleeve 26 is provided outside the reciprocating threaded shaft 25, and a fixing plate 27 is connected to the bottom of the threaded sleeve 26; A cutting blade 28 is provided at the bottom of the fixing plate 27, and a support damper 29 is provided at the bottom of the fixing plate 27, and a fixed pressure roller 30 is connected to the bottom of the support damper 29;

[0039] A device shell is provided at the top of the device main body 1, and the worm 23 is located inside the device shell, and the ratchet group includes a first ratchet 6. A second ratchet 7 is provided at the right end of the first ratchet 6, and a spring shaft 8 is fixedly connected to the right end of the second ratchet 7; The ratchet orientations of the ratchet groups at the right ends of the driving sprocket 3 and the driven sprocket 5 are opposite;

[0040] A set of third bevel gears 15 are provided at both the left and right ends of the first driving shaft 9, and a fourth bevel gear 16 is meshed at the rear end of the third bevel gear 15, and a first gear 17 is connected to the rear end of the fourth bevel gear 16. A second gear 18 is meshed at the top of the first gear 17, and limiting pressure rollers 19 are connected to the rear ends of both the first gear 17 and the second gear 18; The top of the fixing plate 27 is fixedly connected to the threaded sleeve 26, and the threaded sleeve 26 is slidably connected to the bottom of the device shell provided at the top of the device main body 1; A bearing seat is provided inside the device main body 1, and the bearing seat forms a rotational connection with the second bevel gear 11 and the fourth bevel gear 16;

[0041] Working principle: When using the tulle PET cutting device with an auxiliary limiting mechanism, first connect the device power supply to the power grid for power supply, so that the driving motor 2 rotates forward, causing the ratchet group at the right end of the driven sprocket 5 to engage. The driving motor 2 drives the driving sprocket 3 to rotate, and the driving sprocket 3 drives the driven sprocket 5 to rotate through the transmission chain 4. At this time, since the ratchet orientation of the ratchet group at the right end of the driving sprocket 3 is opposite to that of the ratchet group at the right end of the driven sprocket 5, the ratchet group at the right end of the driving sprocket 3 will disengage, causing only the first drive shaft 9 to rotate and the second drive shaft 20 not to rotate;

[0042] When the ratchet groups are engaged, the first ratchet group 6 will engage with the ratchet groove inside the second ratchet 7, causing the driven sprocket 5 to drive the second ratchet 7 to rotate. The second ratchet 7 drives the first drive shaft 9 to rotate through the spring shaft 8. Since the ratchet orientation of the ratchet group at the right end of the driving sprocket 3 is opposite to that of the ratchet group at the right end of the driven sprocket 5, the first ratchet 6 at the right end of the driving sprocket 3 will disengage from the second ratchet 7, causing the second ratchet 7 to retract under the drive of the spring shaft 8, so that the second ratchet 7 is not in a rotating state and cannot drive the second drive shaft 20 to rotate;

[0043] When the first drive shaft 9 rotates, it will drive the first bevel gear 10 to rotate, causing the first bevel gear 10 to drive the second bevel gear 11 and the first sprocket shaft 12 to rotate. Thus, the first sprocket shaft 12 drives the transmission chain 13 to rotate, causing the workpiece to move on top of the transmission chain 13. At the same time, the first drive shaft 9 will also drive the third bevel gear 15 to rotate, causing the third bevel gear 15 to drive the fourth bevel gear 16 and the first gear 17 to rotate. The first gear 17 drives the second gear 18 to rotate in the reverse direction, causing the two limiting pressure rollers 19 to rotate towards each other between the first gear 17 and the second gear 18, thereby squeezing the workpiece. When the limiting pressure rollers 19 stop rotating, they will fix and limit the workpiece;

[0044] When the drive motor 2 rotates in the reverse direction, the ratchet assembly at the right end of the driving sprocket 3 will be engaged, while the ratchet assembly at the right end of the driven sprocket 5 will be disengaged. As a result, the driving sprocket 3 rotates driven by the drive motor 2, causing the driving sprocket 3 to drive the second drive shaft 20 and the fifth bevel gear 21 to rotate, causing the fifth bevel gear 21 to drive the sixth bevel gear 22 to rotate, causing the sixth bevel gear 22 to drive the worm 23 to rotate, and thus causing the worm 23 to drive the turbine 24 and the reciprocating threaded shaft 25 to rotate. Consequently, the threaded sleeve 26 slides driven by the reciprocating threaded shaft 25, causing the threaded sleeve 26 to drive the fixing plate 27 and the cutting blade 28 to move. When the cutting blade 28 is in contact with the top of the workpiece, the fixed pressure roller 30 will also be in contact with the surface of the workpiece. Since the first drive shaft 9 stops rotating, the limit pressure roller 19 stops rotating to fix and limit both ends of the workpiece. Subsequently, the fixed pressure roller 30 will also press and limit the cutting position of the workpiece driven by the support damper 29, so that when the cutting blade 28 cuts, the workpiece will not shift.

[0045] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0046] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
