Description

Technical Field

[0001] This application relates to the field of TPU film slicing technology, and in particular to a distance-slicing device for TPU film production. Background Technology

[0002] In the TPU film production process, the slitting process after winding usually requires fixed-distance slicing. After the TPU film is extruded from the extruder die, it goes through cooling, shaping, traction, and winding to form a continuous roll. To meet the size requirements of different applications (such as clothing, packaging, electronic protective films, etc.), the wound TPU film needs to be sliced ​​at fixed distances according to a predetermined length or width.

[0003] A search revealed Chinese Patent Publication No. CN219468223U, which discloses a film-mounted, spaced-transfer slicing mechanism. The mechanism includes a spaced-transfer machine body. Fixed mounting baffles and fixed mounting blocks are fixedly connected between the front and rear sides of the body. A set of transfer rollers is rotatably connected between the two fixed mounting baffles. A spaced-distance cylinder is rotatably connected between the two fixed mounting baffles on the right side of the transfer rollers. A spaced-distance conveyor belt is movably sleeved between the spaced-distance cylinder and the transfer rollers. A slicing knife device is fixedly installed between the two fixed mounting baffles on the right side of the spaced-distance cylinder. The fixed mounting block is located on the right side of the fixed mounting baffles. This invention effectively solves the problem of collecting spaced-distance transferred slices after packaging, achieving automatic stacking, saving significant manpower, improving production efficiency, and reducing production costs.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent:

[0005] The slicing blade can only slice the TPU film at one station, so there is a waiting time during the film loading or unloading process. At the same time, equipping one station with a laser cutting machine results in a waste of cost.

[0006] Therefore, in response to the above problems, the applicant provides a distance-slicing device for TPU film production. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a distance slicing device for TPU film production.

[0009] A TPU film production fixed-distance slicing device includes an X-axis linear module, a laser cutting head, and a Z-axis linear module. The X-axis linear module is provided with a rotating mechanism that enables the laser cutting head to rotate. The rotating mechanism includes a forward and reverse motor, a gear one, and a gear two. The rotating end of the forward and reverse motor is fixedly connected to the gear one, the gear one meshes with the gear two, and the inner ring of the gear two is fixedly connected to a fixed shaft.

[0010] The Z-axis linear module is equipped with an anti-deviation mechanism to prevent the laser cutting head from deviating. The anti-deviation mechanism includes a spring and a damper.

An "L"-shaped bracket is fixedly connected to the side of frame one and frame two that are far apart from each other, and a laser displacement sensor is bolted on the "L"-shaped bracket.

[0014] Optionally, the top surfaces of frame one and frame two are fixedly connected to the bottom surface of the X-axis linear module.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. This utility model enables the laser cutting head to rotate at a certain degree, allowing it to simultaneously and alternately slice TPU films on two conveyor belts, thus saving the cost of equipping one laser cutting machine on each conveyor belt. At the same time, the use of a single laser cutting head for dual-station operation eliminates the waiting time for film loading or unloading in the original equipment.

The elastic deformation of the spring absorbs energy, and the damper can suppress the high-frequency vibration of the laser cutting head. The spring and the damper form a parallel buffer structure for the laser cutting head, which can prevent the laser cutting head from deviating. Attached Figure Description

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses a distance-slicing device for TPU film production.

[0029] like Figure 1-6 As shown, a TPU film production distance slicing device includes an X-axis linear module 20, a laser cutting head 23, and a Z-axis linear module 22. The X-axis linear module 20 is provided with a rotating mechanism that rotates the laser cutting head 23. The rotating mechanism includes a forward and reverse motor 4, a first gear 5, and a second gear 6. The rotating end of the forward and reverse motor 4 is fixedly connected to the first gear 5, and the first gear 5 meshes with the second gear 6. The inner ring of the second gear 6 is fixedly connected to a fixed shaft 7.

[0030] The Z-axis linear module 22 is equipped with an anti-offset mechanism to prevent the laser cutting head 23 from shifting. The anti-offset mechanism includes a spring 12 and a damper 14. The top and bottom of the spring 12 and the damper 14 are fixedly connected to a connecting plate 10. Threaded holes are opened at the four corners of the four connecting plates 10, and bolts 11 are threadedly connected to the multiple threaded holes.

[0031] Please see Figure 6 It also includes frame one 108 and frame two 109. Both ends of frame one 108 and frame two 109 are fixedly connected to the bottom support of conveyor belt 105, and one side of frame one 108 is fixedly connected to one side of frame two 109.

[0032] Both frame 108 and frame 2 109 consist of legs and a frame. The conveyor belt 105 is placed in the frame. The bottom bracket of the conveyor belt 105 is fixedly installed on both sides of frame 108 and frame 2 109. The conveyor belt 105 is connected to an external power supply.

[0033] Please see Figure 6Two brackets 100 are fixedly connected to the top of the frame of frame 108 and frame 2 109 respectively. TPU film winding rollers 102 are rotatably connected to the two adjacent brackets 100. One end of the TPU film winding rollers 102 is fixedly connected to the rotating shaft of motor 101. A support plate is fixedly connected to the bottom of motor 101 and the support plate is fixedly connected to one side of bracket 100.

[0034] Please see Figure 6 Two brackets 103 are fixedly connected to the top of the frame of frame 108 and frame 2 109 respectively. A flattening roller 104 is rotatably connected to the two adjacent brackets 103. An "L"-shaped bracket 106 is fixedly connected to the side of frame 108 and frame 2 109 that are far apart from each other. A laser displacement sensor 107 is bolted on the "L"-shaped bracket 106. TPU film is laid between the flattening roller 104 and the conveyor belt 105 from two TPU film winding rollers 102. The motor 101 rotates to feed the TPU film on the winding rollers 102. At the same time, the conveyor belt 105 moves the TPU film. The laser displacement sensor 107 measures the distance of the TPU film flowing through it. When the distance needs to be fixed, the laser displacement sensor 107 transmits the signal to the controller. The controller controls the laser cutting machine 2 to work, so that the laser cutting head 23 slices the TPU film. The laser cutting machine 2 is existing technology, and its operation steps and principles will not be described in detail here.

[0035] Please see Figure 6 The top surfaces of frame 108 and frame 209 are fixedly connected to the bottom surface of X-axis linear module 20. An "L"-shaped frame 3 is fixedly connected to the top surface of the sliding end of X-axis linear module 20. A forward / reverse motor 4 is fixedly connected to the "L"-shaped frame 3. Fixed shaft 7 is rotatably connected to the sliding end of X-axis linear module 20. A reinforcing column 8 is fixedly connected to the top of fixed shaft 7. When the forward / reverse motor 4 is turned on, it drives gear 15 to rotate. Gear 15 meshes with gear 26 and drives fixed shaft 7 and reinforcing column 8 to rotate 180 degrees from above frame 108 to above frame 209, as shown in the attached diagram of the instruction manual. Figure 2 The state shown.

[0036] Please see Figure 3 A reinforcing column 8 is fixedly connected to one side of a Y-axis linear module 21. The sliding end of the Y-axis linear module 21 is fixedly connected to one side of a Z-axis linear module 22. The X-axis linear module 20, Y-axis linear module 21, Z-axis linear module 22, and laser cutting head 23 are combined to form a laser cutting machine 2. The forward and reverse motor 4 is turned on, driving gear 5 to rotate. Gear 5 meshes with gear 6, driving the fixed shaft 7, reinforcing column 8, and laser cutting machine 2 to rotate 180 degrees from above frame 108 to above frame 109, as shown in the attached diagram of the instruction manual. Figure 2As shown, the sliding end of the X-axis linear module 20 drives the laser cutting head 23 to move laterally, the sliding end of the Y-axis linear module 21 drives the laser cutting head 23 to move longitudinally, and the sliding end of the Z-axis linear module 22 drives the laser cutting head 23 to move vertically up and down.

[0037] Please see Figure 1 The sliding end of the Z-axis linear module 22 is fixedly connected to the base 9. The base 9 has multiple through holes 90. Bolts 11 are installed on the threaded holes of the connecting plate 10 corresponding to the multiple through holes 90. The connecting plate 10 at the bottom of the spring 12 and the damper 14 is attached to the top of the laser cutting head bracket 13. The laser cutting head 23 is fixedly connected to the laser cutting head bracket 13. The connection between the connecting plate 10 and the base 9 and the laser cutting head bracket 13 is locked by bolts 11, which can eliminate the connection gap and avoid the vibration of the buffer system itself.

[0038] The implementation principle of a TPU film production spacing slicing device according to an embodiment of this application is as follows:

[0039] After the laser cutting head 23 slices the TPU film on frame 108, the controller controls the rotating mechanism to drive the laser cutting head 23 to slice the TPU film on frame 209. The rotation process is as follows:

[0040] The forward and reverse motor 4 is turned on, which drives gear 5 to rotate. Gear 5 meshes with gear 6, causing gear 6 to rotate. The rotation of gear 6 drives the fixed shaft 7, the reinforcing column 8 and the laser cutter 2 to rotate 180 degrees from above frame 108 to above frame 209. Based on the feedback signal from the laser displacement sensor 107 on frame 209, the TPU film on frame 209 is sliced.

[0041] The spring 12 and damper 14 are attached to the base 9 and the laser cutting head bracket 13 respectively through the connecting plate 10 and locked by the bolt 11. The spring 12 can quickly respond to the impact force on the laser cutting head 23, such as uneven TPU film surface or conveyor belt vibration. The elastic deformation of the spring 12 absorbs energy and avoids the laser cutting head 23 from deflection caused by rigid impact. The damper 14 can suppress the high-frequency vibration of the laser cutting head 23, so that the laser cutting head 23 can achieve passive height compensation when the film surface is uneven. The weight of the laser cutting head 23 and the spring preload work together to form a dynamic equilibrium point, thereby covering the thickness fluctuation and surface deformation common in TPU film. The spring 12 and damper 14 form a parallel buffer structure for the laser cutting head 23, which can prevent the laser cutting head 23 from deflection.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
