[0044] See also Figure 1-Figure 4 In an embodiment of the present invention, a cutting device for a polyester film tape includes an equipment body composed of a cabinet 1 and a feeding component 2. The cabinet 1 includes a control box that is arranged in a left-right symmetrical manner, and the two control boxes are spliced ​​by a crossbar group. The crossbar group includes three crossbars, and the two ends of the crossbars are respectively mounted on the outer wall of the corresponding control box. There are various assembly methods between the crossbars and the control box, such as bolt connection, welding and riveting. The three crossbars are arranged in a triangular state between the two control boxes, so as to enhance the splicing stability of the cabinet 1.

[0045] The feeding component 2 is composed of a wing plate 21 and an auxiliary component 22. There are two wing plates 21, which are respectively arranged on the rear outer wall of the corresponding control box, and the two wing plates 21 are symmetrically arranged. There are various ways to assemble the wing plate 21 and the control box, such as welding, riveting and bolting. In this embodiment, welding is used for assembly. A tape mother roll for tape roll production is movably connected between the two wing plates 21.

[0046] The cabinet 1 is equipped with a guide mechanism for guiding materials, a slitting mechanism 5 for slitting the tape, and a winding component for winding the tape. There are two winding components, which are staggered up and down, with the upper winding component being arranged horizontally and the lower winding component being arranged vertically. The staggered arrangement of the two winding components is beneficial to preventing the cut tapes from being entangled with each other when winding the tape.

[0047] See also Figure 2 , Figure 6 , Figure 7 , Fig.13 and Fig.14 In the embodiment of the present invention, the winding component is composed of a winding mechanism 3, a cutting piece 4 and an adsorbent 14. Among them, the cutting piece 4 is located at the lower side of the winding mechanism 3, and is used to cut the tape roll mounted on the winding mechanism 3. The cutting piece 4 is at a 45-degree angle below the side of the winding mechanism 3. The adsorbent 14 is located on the outside of the winding mechanism 3, and is used to adsorb the wound tape. The negative pressure generated by the adsorbent 14 adsorbs the wound tape, so that the tape will not be scattered after being cut, thereby further facilitating the subsequent winding operation of the tape by the winding mechanism 3.

[0048] The winding mechanism 3 is composed of a winding assembly, a base assembly 35, a second motor 36 and a movable assembly 37. The second motor 36 is used to drive the winding assembly to rotate. When the second motor 36 drives the winding assembly to rotate, the movable assembly 37 performs corresponding movement on the base assembly 35.

[0049] The winding assembly includes symmetrically arranged material rollers 31, and the left ends of the two material rollers 31 are provided with left end pieces 33. The right ends of the two material rollers 31 are provided with right end pieces 34. Through the arrangement of the left end pieces 33 and the right end pieces 34, the parallel assembly of the two material rollers 31 is realized. When the motor 2 36 drives the winding mechanism 3 to rotate 45 degrees, the material roller 31 in the winding assembly is tangent to the cutting piece 4, thereby realizing the cutting operation of the tape roll set on the material roller 31.

[0050] Both ends of each material roller 31 are provided with a clamping member 32, and the plurality of clamping members 32 are respectively clamped on the corresponding left end member 33 and right end member 34. The convenient assembly and disassembly of the clamping member 32 on the left end member 33 and the right end member 34 enables the convenient assembly and disassembly of the material roller 31. The basic assembly 35 and the movable assembly 37 are both arranged on the right end member 34, wherein the movable assembly 37 is movably connected to the basic assembly 35.

[0051] See also Figure 4 and Fig.11In the embodiment of the present invention, the auxiliary part 22 includes a side arm rotatably connected to the inner wall of the corresponding wing plate 21 through a pin shaft. A pressure roller 221 for limiting the position of the tape is movably connected between the two side arms, and two carrier plates are arranged on the pressure roller 221, and a silencer roller 222 for silencing is installed between the two carrier plates. Among them, the silencer roller 222 is located below the pressure roller 221. Through the cooperation of the pressure roller 221 and the silencer roller 222, the tape pulled out from the tape mother roll is restrained and released, and the stability of the tape release state is guaranteed. In addition, the cooperation of the pressure roller 221 and the silencer roller 222 can lock the pulled out tape when the equipment is not in use, so as to avoid the waste caused by the accidental release of the pulled out tape. The setting of the silencer roller 222 reduces the noise generated by the release of the tape when the equipment is running, and further improves the comfort during the use of the equipment.

[0052] The front side of each side arm is equipped with a cylinder located on the inner wall of the corresponding wing plate 21, and the output end of the cylinder is movably connected to the corresponding side arm. The cylinder drives the side arm, and then when the equipment is in use, the side arm is adjusted to make the auxiliary part 22 move as a whole, and the silencer roller 222 configured thereon is lowered to avoid limiting the position of the tape. When the equipment is stopped, the side arm is adjusted to make the auxiliary part 22 move as a whole, and the silencer roller 222 configured thereon is lowered, thereby locking the tape.

[0053] See also Figure 7 and Fig. 9 In the embodiment of the present invention, the clamping member 32 includes a spring telescopic rod 321 fixedly connected to the end of the material roller 31 by screws. The output end of the spring telescopic rod 321 is fixedly connected to an end plate 322, and a cross clamping block 323 for plugging is integrally provided on the side of the end plate 322 away from the spring telescopic rod 321. The diameter of the clamping member 32 is smaller than the diameter of the material roller 31, so as not to hinder the installation of the tape reel.

[0054] See also Figure 6-Figure 7 In the embodiment of the present invention, the left end piece 33 is composed of a joint plate 331, a telescopic rod 332, a disc 333 and a cross clamping sleeve 1. The cross clamping sleeve 1 includes two, which are symmetrically rotatably connected to the same side wall of the joint plate 331, and the cross clamping sleeve 1 and the corresponding cross clamping block 323 are plugged and limited. The cross clamping block 323 in the clamping member 32 can realize displacement adjustment when the end plate 322 is adjusted horizontally, thereby realizing the plug-in assembly of the cross clamping block 323 in the cross clamping sleeve 1.

[0055] The telescopic rod 1 332 is rotatably connected to the left outer wall of the joint plate 331. The disc 333 is arranged on the left end shell wall of the telescopic rod 1 332, and the disc 333 is fixedly connected to the corresponding outer wall of the left control box by bolts. A return spring 1 located on the telescopic rod 1 332 is sleeved between the disc 333 and the joint plate 331. Through the configuration of the return spring 1 and the telescopic rod 1 332, the winding assembly in the winding mechanism 3 can be stably adjusted in lateral displacement, thereby ensuring the misalignment requirement of its feeding roller 31.

[0056] See also Figure 6 , Figure 7 and Fig. 9 In the embodiment of the present invention, the right end member 34 includes a base plate 341 disposed at the right end of the material roller 31, and holes are symmetrically opened on the base plate 341, and a cross clamping sleeve 2 345 is rotatably connected in the hole. The cross clamping sleeve 2 345 and the corresponding cross clamping block 323 are also inserted and limited. The assembly between the cross clamping sleeve 2 345 and the cross clamping block 323 enables the material roller 31 to be loaded and unloaded on the left end member 33 and the right end member 34 simply by adjusting the corresponding clamping member 32 during the loading and unloading operation.

[0057] A shell cover 342 for sealing is installed on the right shell wall of the base plate 341 by screws. Two carriers 343 located on the side wall of the base plate 341 are arranged inside the shell cover 342, and the carriers 343 correspond to the cross ferrules 2 345 one by one. A motor 1 344 is installed on each carrier 343, and the motor 1 344 is used to drive the cross ferrule 2 345 to rotate. A rotating shaft is installed at the output end of the motor 1 344, and the end of the rotating shaft away from the motor 1 344 is assembled on the corresponding cross ferrule 2 345. Then, when the motor 1 344 rotates, the corresponding cross ferrule 2 345 is driven to move synchronously, and the self-rotation movement of the material roller 31 is realized through the cooperation of the clamping member 32 and the left end member 33.

[0058] A second telescopic rod 346 is fixedly connected to the right outer wall of the shell cover 342. The end of the second telescopic rod 346 away from the shell cover 342 penetrates the corresponding control box side wall and is assembled with the second motor 36. The second motor 36 is fixedly connected to the inner wall of the corresponding control box by bolts, and then the movement of the second motor 36 drives the second telescopic rod 346 to rotate, thereby driving the right end piece 34 to move, and with the cooperation of the left end piece 33, the material roller 31 is synchronously realized. A second reset spring for reset movement is also sleeved on the second telescopic rod 346. The setting of the second reset spring corresponds to the first reset spring, so as to ensure that the winding assembly is in a stable state under the condition of bidirectional force.

[0059] See also Figure 2 , Figure 5 , Figure 6 and Figure 8In the embodiment of the present invention, the base assembly 35 includes a carrier plate 351 sleeved on the second telescopic rod 346, and the carrier plate 351 is fixedly connected to the right control box. A through hole is opened at the center of the carrier plate 351, and the carrier plate 351 is sleeved on the second telescopic rod 346 through the through hole, and then there is no connection between the carrier plate 351 and the second telescopic rod 346.

[0060] An annular column 352 is installed on the side wall of the carrier plate 351 by screws, and a winding groove is opened on the side wall of the annular column 352. The winding groove includes two circles, wherein the first circle is an outer circle and the second circle is an inner circle, and the initial end of the outer circle and the terminal end of the inner circle are connected by an inclined groove. The clearance of the inclined groove is smaller than the clearance of the winding groove.

[0061] The depth distribution of the winding groove on the base component 35 in the upper winding mechanism 3 is deep in the outer circle and shallow in the inner circle, and the depth distribution of the winding groove on the base component 35 in the lower winding mechanism 3 is shallow in the outer circle and deep in the inner circle.

[0062] The inner circle of the upper winding groove has the same depth as the outer circle in the range of 0 to 90 degrees, thereby ensuring that the material roller 31 disposed thereon will not be displaced when passing over the corresponding cutting piece 4 during the revolution of the winding assembly. In the range of 90 to 180 degrees, the depth of the inner circle gradually increases until the winding assembly can complete a mileage of displacement, after which the depth of the inner circle remains unchanged.

[0063] The inner circle of the winding groove at the bottom has the same depth as the outer circle in the range of 0 to 90 degrees, thereby ensuring that the material roller 31 arranged thereon will not be displaced when passing over the corresponding cutting piece 4 during the revolution of the winding assembly. In the range of 90 to 180 degrees, the depth of the inner circle gradually decreases until the winding assembly can complete a mileage of displacement, after which the depth of the inner circle remains unchanged.

[0064] See also Figure 6-Figure 9 In the embodiment of the present invention, the movable assembly 37 is composed of a slide rail 371, a slide sleeve and a telescopic slide rod 372. The slide rail 371 is fixedly connected to the right outer wall of the housing 342 by screws. The slide sleeve is slidably connected to the slide rail 371, the telescopic slide rod 372 is fixedly connected to the side wall of the slide sleeve, and the ends of the telescopic slide rod 372 away from the slide sleeve are respectively movably connected to the corresponding winding grooves.

[0065] A groove is provided on the slide rail 371, a guide rod is provided in the groove, and an extrusion spring and a moving block are sleeved on the guide rod, wherein the side of the moving block away from the groove is fixedly connected to the slide sleeve. The telescopic slide rod 372 adopts an elastic telescopic rod structure, and a ball is rollingly connected to its output end, and the ball rolls and contacts in the winding groove and the inclined groove. The outer rod in the telescopic slide rod 372 is suitable for activities in the winding groove, and the outer rod in the telescopic slide rod 372 is suitable for activities in the inclined groove. Therefore, when the telescopic slide rod 372 rotates in the winding groove, there will be no linear phenomenon of the telescopic slide rod 372 moving from the inclined groove. When the inner rod passes through the inclined groove, under the reset action of the reset spring 1 and the reset spring 2, combined with the elastic reset action of the telescopic slide rod 372 itself, the telescopic slide rod 372 enters the inclined groove when it rotates to the inclined groove position and stretches. Then, under the resetting action of the extrusion spring and the moving block, the telescopic slide bar 372 is reset on the slide rail 371 , thereby enabling the telescopic slide bar 372 to enter the outer ring of the winding groove.

[0066] See also Figure 2 and Fig.12 In the embodiment of the present invention, the guide mechanism includes a loading roller 6, a steering roller 7, a spreading roller 8, a dispersion roller 9, a bearing roller 10, a bearing roller 2 11 and a bearing roller 3 12 movably connected between two control boxes. The adhesive tape released from the tape mother roll passes through the auxiliary part 22, passes through the loading roller 6, the steering roller 7 and the spreading roller 8, and then is wound on the dispersion roller 9. In the process of the adhesive tape from the spreading roller 8 to the dispersion roller 9, the slitting mechanism 5 is equidistantly slit, so that the whole adhesive tape is divided into a plurality of equidistant adhesive tape strips. Among them, the dispersion roller 9 is used to carry the slit adhesive tape. The bearing roller 10 is located at the rear side of the lower winding mechanism 3, and the bearing roller 2 11 is located at the rear side of the upper winding mechanism 3. After the plurality of adhesive tape strips pass through the steering bearing of the dispersion roller 9, except for the edge materials on both sides, they are divided into odd and even numbers. The odd adhesive tape strips are wound by the winding mechanism 3 arranged above the bearing roller 2 11, and the even adhesive tape strips are wound by the winding mechanism 3 arranged below the bearing roller 10.

[0067] The bearing roller 3 12 is used for steering the edge material. A roller edge collection mechanism 13 located between two control boxes is provided above the bearing roller 3 12. The roller edge collection mechanism 13 is used for collecting the edge material. The roller edge collection mechanism 13 uses the existing technology to reel up the edge material carried by the bearing roller 3 12, thereby preventing the edge material of the tape from causing adverse effects on the production of the tape.

[0068] See also Figure 1-Figure 4 In the embodiment of the present invention, the cutting piece 4 is composed of a rod body and a knife disc. The knife disc includes a plurality of knife discs linearly distributed on the rod body, and the two ends of the rod body are respectively arranged on the corresponding control box. The equidistant arrangement of the knife discs in the cutting piece 4 realizes equidistant cutting of the tape roll on the material roller 31.

[0069] See also Figure 1 and Fig.14 In an embodiment of the present invention, the adsorption component 14 is composed of a hollow tube and a negative pressure generator. The negative pressure generator is arranged inside the hollow tube, and a plurality of adsorption holes for airflow are linearly opened on the peripheral wall of the hollow tube, and the two ends of the hollow tube are slidably connected to the corresponding control box respectively. The negative pressure generator generates a negative pressure effect inside the hollow tube, and the negative pressure of the hollow tube causes each adsorption hole opened thereon to act with negative pressure, thereby adsorbing the tape passing thereon. The current adsorption force does not hinder the winding of the tape, but can only ensure that the tape will not be scattered after cutting.

[0070] A plurality of movable grooves are provided on the corresponding side walls of the two control boxes, each movable groove is slidably connected with a support block, the two ends of the hollow tube are respectively loaded on the corresponding support blocks, and each movable groove is provided with a reset spring 3. The reset spring 3 is provided to ensure the movement and reset of the adsorbent 14, so that the adsorbent 14 can not only ensure the adhesion between the tape and the tape short barrel on the material roller 31 in the initial state of the tape during the tape winding process, but also ensure that the tape winding will not be hindered due to the increase in the thickness of the tape after the tape is wound.

[0071] The suction member 14 in the upper winding component is located between the winding mechanism 3 and the second bearing roller 11, and the moving direction of the suction member 14 is lateral movement. Then, the adhesive tape can be wound around the corresponding winding mechanism 3 after passing through the suction member 14. When the adhesive tape passes through the suction member 14, the negative pressure generated by the suction member 14 adsorbs the adhesive tape.

[0072] The suction member 14 in the lower winding component is located directly above the winding mechanism 3, and the movement direction of the suction member 14 is longitudinal movement. Then, when the adhesive tape is wound with the winding mechanism 3, it will pass under the suction member 14, and then the suction member 14 will absorb the passing adhesive tape.

[0073] When the adsorption member 14 is assembled, the side with the adsorption hole is oriented toward the winding mechanism 3 .

[0074] See also Figure 4 and Fig.10In the embodiment of the present invention, the slitting mechanism 5 is located between the spreading roller 8 and the dispersing roller 9. The slitting mechanism 5 is composed of an L-shaped plate 51, an electric push rod 52, a transverse plate 53 and a blade group 54. Among them, the L-shaped plate 51 and the electric push rod 52 each include two, and the two electric push rods 52 are respectively installed on the top shell wall of the corresponding L-shaped plate 51, and the output end of the electric push rod 52 passes through the top shell wall of the L-shaped plate 51. The two L-shaped plates 51 are respectively fixedly connected to the outer wall of the corresponding control box by bolts, and a guide block is slidably connected to the side wall of each L-shaped plate 51. The output end of the electric push rod 52 is installed on the transverse plate 53, and then the lifting and lowering adjustment of the transverse plate 53 is realized through the control of the electric push rod 52.

[0075] The two ends of the horizontal plate 53 are fixedly connected to the corresponding guide blocks. The arrangement of the horizontal plate 53 on the guide blocks ensures the stability of the horizontal plate 53 when it is lifted and lowered. The blade assembly 54 includes a plurality of blades, which are linearly distributed on the bottom shell wall of the horizontal plate 53, and the blades are fixed to the horizontal plate 53 by fastening bolts. The detachable assembly of the blades on the horizontal plate 53 allows the blades to be loaded with adjustable distances, thereby realizing the slitting of the tape into different widths, further improving the scope of use of the equipment.

[0076] The working principle of the present invention is: after the corresponding material rollers 31 on the winding mechanisms 3 in each winding component are equipped with tape reels for winding tape, the motor 2 36 of the winding mechanisms 3 in each winding component is turned on through the control panel distributed on the corresponding control cabinet on the cabinet 1, so as to realize the counterclockwise rotation of the winding assembly in the corresponding winding mechanism 3.

[0077] The operation of the second motor 36 drives the second telescopic rod 346 in the right end piece 34 assembled therewith to move synchronously, and the second telescopic rod 346 is assembled with the shell cover 342, so that each material roller 31 in the winding mechanism 3 can perform orbital motion with the cooperation of the left end piece 33.

[0078] During the rotation of the winding assembly, when it gradually approaches the corresponding cutting piece 4, the corresponding motor 1 344 in the right end piece 34 operates, causing the corresponding cross clamping sleeve 2 345 to rotate. During the rotation process, the cross clamping sleeve 2 345 drives the corresponding material roller 31 to rotate in cooperation with the left end piece 33 through the clamping piece 32 plugged and assembled with it.

[0079] As the material roller 31 revolves and rotates, the tape reel mounted thereon comes into contact with the corresponding cutting piece 4 during the movement, thereby realizing the cutting operation of the tape reel mounted on the material roller 31, so that the complete tape reel is formed into short tape reels of equal width.

[0080] When the tape roll on the material roller 31 is cut, the motor 1 344 stops moving. The winding mechanism 3 stops the revolution after rotating 180 degrees. At this time, not only the tape roll on one of the material rollers 31 is cut, but also the cut material roller 31 is in the winding position for winding the tape.

[0081] After the adjustment of the winding mechanism 3 is completed, due to the effect of the adsorption of the adhesive tape by the adsorption member 14 in advance, when the material roller 31 is in the winding station, the slit adhesive tape carried by the carrier roller 10 and the carrier roller 2 11 is automatically attached to the corresponding adhesive tape short drum. Then, the motor 1 344 corresponding to the material roller 31 in the winding station is turned on again to realize the winding of the adhesive tape.

[0082] When the tape is wound to an appropriate length, the motor 1 344 stops running. Then, the motor 2 36 is turned on, driving the winding assembly to rotate counterclockwise again. The winding assembly repeats the above steps during the rotation process, and then when the winding assembly rotates 180 degrees again, not only the slitting of the tape roll on another material roller 31 in the same winding assembly is completed, but also the tape roll is transposed to the winding station. When it is transposed to the winding station, the material roller 31 wound with the tape is transposed. At this time, the traction angle on it adheres to the corresponding tape short roll on the newly transposed material roller 31 under the action of the rotation of the winding assembly. Then, the staff holds a cutting tool to cut the tape between the two material rollers 31, so as to facilitate the winding process of the tape by the newly transposed material roller 31.

[0083] After the two material rollers 31 in the same winding mechanism 3 have completed the first winding of the tape, the cutting tool is used to cut the tapes wound on the corresponding tape short barrels again. The cut tapes are adsorbed by the corresponding adsorbents 14 to ensure that the tapes to be wound are always in the corresponding position. At this time, the tapes wound by the multiple tape short barrels on each material roller 31 are distributed in intervals, and the winding mechanism 3 completes a circle of rotation adjustment. At this time, the telescopic slide bar 372 of the movable component 37 in the winding mechanism 3 is in the first circle of the winding groove on the annular column 352 in the base component 35, and the winding component in the winding mechanism 3 will not be misaligned when it revolves.

[0084] At this time, the distribution of the tape wound on the multiple tape short barrels on the material rollers 31 in the upper and lower winding mechanisms 3 is different. The motor 2 36 is started again, so that the material roller 31 that has completed the tape winding for the first time rotates 180 degrees counterclockwise again, so that it reaches the winding station. During the rotation and transposition process of the winding assembly this time, the telescopic slide bar 372 of the movable assembly 37 in the winding mechanism 3 is in the second circle of the winding groove on the annular column 352 in the base assembly 35. Then, the winding assembly achieves overall displacement in the process from 90 degrees to 180 degrees due to the guiding action of the winding groove of the annular column 352 in the base assembly 35. The winding assembly is displaced as a whole by the distance of a tape short barrel, so that the tape short barrels that were not wound on each material roller 31 for the first time move to the position corresponding to the tape. At this time, the material roller 31 reaches the winding station again, and the tapes adsorbed on each adsorbent 14 are attached to the corresponding tape short barrels by themselves.

[0085] When the upper winding mechanism 3 performs the second circle movement, the corresponding inner circle of the winding groove is shallow, so the winding assembly moves to the left. When the lower winding mechanism 3 performs the second circle movement, the corresponding inner circle of the winding groove is deep, so the winding assembly moves to the right. When the winding assembly in the winding mechanism 3 performs displacement movement, the stability of the displacement adjustment of the winding assembly is guaranteed by the cooperation of the telescopic rod 1 332 and the return spring 1 in the left end piece 33, and the cooperation of the telescopic rod 2 346 and the return spring 2 in the right end piece 34.

[0086] After the revolution adjustment of the winding mechanism 3 is completed, the corresponding motor 2 36 is turned off, and the motor 1 344 at the corresponding position is started to realize the winding of the tape. After the current material roller 31 completes the winding operation of the tape, the above steps are repeated, first the corresponding motor 1 344 is turned off, and then the motor 2 36 is started, so that the winding mechanism 3 performs the revolution movement, thereby realizing the replacement of different material rollers 31 in the same winding assembly. In this way, the winding setting of the tape on multiple tape short drums on the material roller 31 is realized.

[0087] After the tape is wound, the clamping member 32 connecting the left end member 33 and the right end member 34 is adjusted to realize the convenient disassembly of the material roller 31. Then, the material of each tape roll on it is unloaded, and a new tape reel is re-installed, and finally, the material roller 31 is loaded on the corresponding winding mechanism 3. When multiple material rollers 31 on the same winding mechanism 3 are replaced, the corresponding motor 2 36 is started, and after the winding assembly moves counterclockwise for a distance, the telescopic slide bar 372 in the movable assembly 37 moves to the inclined groove displacement of the winding groove, and then the telescopic slide bar 372 is quickly reset under the action of the sliding sleeve reset, the reset spring 1 and the reset spring 2. The telescopic slide bar 372 moves quickly along the inclined groove, and then the telescopic slide bar 372 comes to the first circle position of the winding groove again, and synchronously drives the corresponding winding assembly to reset, so as to ensure that the tape reel on the material roller 31 can perform normal cutting operation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
