However, when the current slitting device is used, firstly, the loading and unloading operations of the transparent tape roll when slitting and installing and when removing after slitting are relatively cumbersome, which will consume a certain amount of time and affect the efficiency of the slitting operation of the transparent tape. At the same time, it is not convenient to adjust the slitting distance, resulting in a small number of width specifications of the transparent tape that can be slid, which leads to great limitations in its use.

[0018] The above-mentioned transparent tape slitting device with adjustable distance is used, specifically in the process of slitting and using the transparent tape, because at the beginning, the support plate is stuck between the matching grooves at the front and rear positions by means of vertical sliding cooperation with the matching groove, and at the same time, the limit rod is longitudinally slidably cooperated with the limiting hole, then at this time, the support plate can be vertically slidably cooperated with the matching groove and the limit rod can be longitudinally slidably cooperated with the limiting hole to lock the position height of the support plate and make the axial end of the threaded positioning rod supported by the constraint groove, and then the constraint groove can limit and support the axial end of the threaded positioning rod, so that the threaded positioning rod can more stably drive the transparent tape roll to rotate and cut, and specifically for the transparent tape When the reel is constrained and fixed at the periphery of the threaded positioning rod, it is only necessary to pull the limit rod out of the limit hole to make the support plate slide down vertically along the matching groove to separate the constraint groove from the axial end of the threaded positioning rod, thereby facilitating the smooth installation or removal of the transparent tape reel from the axial end of the threaded positioning rod, ensuring that the transparent tape reel can be quickly installed during slitting, and at the same time ensuring that the transparent tape reel can be quickly detached after slitting is completed. Specifically, in operation, the handles at the front and rear positions are pulled outward at the same time, and the limit rods are all pulled out of the corresponding limit holes by the stretching of the spring. After the limit rods are all out of the limit holes, the support plate slides down by vertically sliding with the matching groove. This process During the process, the constraint groove slides down vertically. Since the distance between the bottom surface of the support plate and the bottom of the matching groove is greater than the vertical groove length of the constraint groove, the support plate can drive the constraint groove to slide down to the top end below the threaded positioning rod, and then the movable limit plate is disengaged from the outer end of the threaded positioning rod by twisting the threaded sleeve, and then the transparent tape roll to be cut is installed by coaxially sliding with the outer periphery of the threaded positioning rod through the inner periphery until the end face of the transparent tape roll abuts against the fixed limit plate, and then the threaded sleeve is installed again by coaxially threading with the threaded positioning rod and the threaded sleeve is twisted to drive the movable limit plate to move to abut against the other end face of the transparent tape roll, thereby completing the transparent tape roll. When the handle is released, the spring will release the tension state and drive the inner ends of the limit rods to be inserted into the corresponding limit holes, so as to complete the support of the constraint groove on the outer ends of the threaded positioning rods again. Then, the spacing between the slitting turntables of the reel slitting assembly can be adjusted. When adjusting, loosen the limit screw.Then, the sleeve of the roll slitting assembly can slide axially along the mounting shaft and the spacing between the plurality of slitting discs can be adjusted and locked by tightening the limit screw, so that the slitting distance of the transparent tape roll can be adjusted. During the adjustment process, the slitting position can be determined by comparing with the fixed transparent tape roll, so that transparent tapes of different widths can be slid by adjusting the spacing between the slitting discs, thereby enriching the general use range of the roll slitting assembly. At the same time, before the slitting operation, when the roll slitting assembly is assembled between the U-shaped seats, the mounting shaft is placed horizontally between the fixed chuck and the movable chuck and compared coaxially, and then the locking nut is screwed to close the fixed chuck. The handle is approached, and then the handle is held to drive the stud to rotate clockwise. The forward rotation of the stud can drive the slots of the movable chuck and the fixed chuck to approach and slide laterally with the plug blocks at both ends of the installation shaft of the reel slitting assembly respectively. When the stud rotates forward until the movable chuck and the fixed chuck contact the two ends of the installation shaft respectively, the stud cannot continue to rotate. The stud is kept from rotating and the locking nut is tightened on the surface of the U-shaped seat, so as to prevent the stud from rotating freely through the friction between the locking nut and the surface of the U-shaped seat, and at the same time, the locking nut is tightened to further prevent the stud from rotating freely by the threaded engagement degree of the stud and the U-shaped seat. The column rotates freely, and then the reel slitting assembly can be detachably fixed between the movable chuck and the fixed chuck by the way that the movable chuck and the fixed chuck are close to each other, so that the reel slitting assembly and the slitting drive assembly can be detachably combined together. The fixed combination method of the reel slitting assembly and the slitting drive assembly is simple and easy to operate, which is convenient for slitting the transparent tape reel after the reel slitting assembly and the slitting drive assembly are combined. When the reel slitting assembly needs to be removed, the locking nut is loosened, and then the slots of the movable chuck and the fixed chuck can be driven to align with the mounting holes of the reel slitting assembly respectively by the way of counterclockwise reversal of the stud. The insert blocks at both ends of the mounting shaft move away from and separate from each other, and then the reel slitting assembly can be disassembled from between the movable chuck and the fixed chuck in a manner that the movable chuck and the fixed chuck move away from each other, so that the reel slitting assembly and the slitting drive assembly can be separated from each other. The method for disassembling the reel slitting assembly and the slitting drive assembly is simple and easy to operate, which is convenient for regular maintenance after the reel slitting assembly is disassembled from the slitting drive assembly. At the same time, since the reel slitting assembly and the slitting drive assembly can be quickly combined and disassembled, after the reel slitting assembly is disassembled from the slitting drive assembly, the slitting turntable can be quickly disassembled by the sleeve sliding off from the end along the mounting shaft.At the same time, the slitting turntable can be quickly installed by installing the sleeve along the mounting shaft from the end, thereby realizing the adjustment of the number of the slitting turntables of the roll slitting assembly, and facilitating the slitting of transparent tapes of different widths by adjusting the number of the slitting turntables, further enriching the general use scope of the roll slitting assembly. When it comes to the slitting operation, the cylinder body is connected to the external air supply pipeline and then works, and the drive motor 1 and the drive motor 2 are respectively electrically connected to the external power supply cable and then work, and the cylinder body drives the U-shaped seat, the mounting shaft of the roll slitting assembly and the slitting turntable through the push rod. The drive motor 1 drives the installation shaft and the slitting turntable of the roll slitting assembly to rotate through the motor shaft 1, and the drive motor 2 drives the threaded positioning rod and the transparent tape roll to be slit to rotate through the motor shaft 2. Then, the slitting turntable of the roll slitting assembly can slit the rotating transparent tape roll by rotating and approaching the transparent tape roll. After the slitting operation is completed, the roll slitting assembly is first moved back longitudinally and stopped rotating, and the threaded positioning rod and the transparent tape roll are also stopped. Then, the slit transparent tape roll is detached from the outer end of the threaded positioning rod according to the above operation method.

[0019] The beneficial effects are as follows: 1. The utility model can adjust and lock the spacing between multiple slitting turntables by sliding the sleeve of the roll slitting assembly axially along the installation shaft and tightening the limit screw, so that the slitting distance of the transparent tape roll can be adjusted, and transparent tapes of different widths can be slid by adjusting the spacing between the slitting turntables, thereby enriching the general use range of the roll slitting assembly;

[0020] 2. The forward rotation of the stud can drive the slots of the movable chuck and the fixed chuck to approach and laterally slide with the plug blocks at both ends of the roll slitting assembly, and then the movable chuck and the fixed chuck can be detachably fixed between the movable chuck and the fixed chuck by approaching each other, so that the roll slitting assembly and the slitting drive assembly can be detachably combined together. The fixed combination method of the roll slitting assembly and the slitting drive assembly is simple and easy to operate, which is convenient for slitting the transparent tape roll after the roll slitting assembly and the slitting drive assembly are combined;

[0021] 3. The reversal of the stud can drive the slots of the movable chuck and the fixed chuck to move away from the plug blocks at both ends of the roll slitting assembly and separate from each other, and then the roll slitting assembly can be separated from the movable chuck and the fixed chuck by moving the movable chuck and the fixed chuck away from each other, so that the roll slitting assembly and the slitting drive assembly can be separated from each other. The separation method of the roll slitting assembly and the slitting drive assembly is simple and easy to operate, which is convenient for regular maintenance after the roll slitting assembly is separated from the slitting drive assembly;

[0022] 4. Since the roll slitting assembly and the slitting drive assembly can be quickly combined and disassembled, after the roll slitting assembly is disassembled from the slitting drive assembly, the slitting turntable can be quickly detached by sliding the sleeve from the end along the mounting shaft, and the slitting turntable can be quickly installed by installing the sleeve from the end along the mounting shaft, thereby realizing the adjustment of the number of slitting turntables of the roll slitting assembly, facilitating the slitting of transparent tapes of different widths by adjusting the number of slitting turntables, further enriching the general use range of the roll slitting assembly;

[0023] 5. The support plate can be locked in height by means of vertical sliding cooperation between the support plate and the matching groove and longitudinal sliding cooperation between the limit rod and the limit hole, and the axial end of the threaded positioning rod can be supported by the constraint groove. Then, the threaded positioning rod can be more stably driven to rotate and cut the transparent tape roll by means of limiting support of the axial end of the threaded positioning rod by the constraint groove.

[0024] 6. Simply pull the limit rod out of the limit hole to allow the support plate to slide vertically along the matching groove to separate the constraint groove from the axial end of the threaded positioning rod, thereby facilitating the smooth installation or removal of the transparent tape roll from the axial end of the threaded positioning rod, ensuring that the transparent tape roll can be quickly installed during slitting, and at the same time ensuring that the transparent tape roll is quickly removed after slitting.

The outer end surfaces of the slitting turntables 602 are coaxially fixed with sleeves 603, and the slitting turntables 602 and the sleeves 603 are both coaxially slidably fitted on the periphery of the mounting shaft 601. The sleeves 603 are radially interspersed with limit screws 604 in a threaded engagement manner, and the inner ends of the limit screws 604 can be pressed against the periphery of the mounting shaft 601. The purpose of such a setting is that the sleeve 603 of the roll slitting assembly 6 can slide axially along the mounting shaft 601 and tighten the limit screws 604 to adjust and lock the spacing between the multiple slitting turntables 602, so that the slitting distance of the transparent tape roll can be adjusted.

[0049] See also Figure 1-Figure 11As shown, the support assembly 3 is optimized as follows: the horizontal cross-section of the matching groove 304 is rectangular, the matching groove 304 is a blind groove in the vertical direction and is opened from top to bottom, and the distance between the bottom surface of the support plate 305 and the bottom of the matching groove 304 is greater than the vertical groove length of the constraint groove 302. This arrangement first facilitates the matching groove 304 to have a good positioning guide design during the vertical sliding of the support plate 305 along the matching groove 304, and at the same time facilitates the matching groove 304 to have a sufficient length in the vertical direction so that the support plate 305 can be lowered to the lowest position where the top of the constraint groove 302 is lower than the threaded positioning rod 405. The bottom of the constraint groove 302 is arc-shaped and fits and contacts the lower part of the outer periphery of the end of the threaded positioning rod 405. This arrangement enables the constraint groove 302 to stably support the rotation of the threaded positioning rod 405, and avoids the situation where the shaft end of the threaded positioning rod 405 jumps during the rotation process.

[0050] See also Figure 1-Figure 11 As shown, the roll fixing component 4 and the roll cutting component 6 are respectively optimized as follows. Specifically, in the roll fixing component 4, the outer periphery of the threaded positioning rod 405 is coaxially slidably matched with the inner periphery of the transparent tape roll to be cut, and specifically in the roll cutting component 6, the cutting turntable 602 is a circular disk and the outer diameter is larger than the outer diameter of the transparent tape roll to be cut. Such an arrangement first makes it easier for the transparent tape roll to be cut to be smoothly sleeved on the outer periphery of the threaded positioning rod 405, and at the same time ensures that the cutting turntable 602 can successfully complete the cutting operation on the transparent tape roll.

[0051] See also Figure 1-Figure 11 As shown, the disassembly assembly 2 is optimized as follows: the cross-sectional shapes of the plug block 207 and the slot 206 along the longitudinal vertical plane are both rectangular, and the lateral length of the plug block 207 is not greater than the lateral groove depth of the slot 206. This arrangement first facilitates a good positioning and guiding design when the plug block 207 and the slot 206 are matched, and at the same time facilitates the motor shaft 102 to drive the installation shaft 601 to rotate after the plug block 207 and the slot 206 are slidably matched, and facilitates the movable chuck 201 and the fixed chuck 208 to be respectively pressed at the two end positions of the installation shaft 601. The portion of the stud 205 extending out of the outside of the U-shaped seat 106 is coaxially engaged with a locking nut 204, and the outer end of the stud 205 is coaxially fixed with a handle 203. The purpose of the above-mentioned arrangement is, firstly, to facilitate the rotation of the stud 205 by holding the handle 203, and at the same time, when the locking nut 204 is pressed against the surface of the U-shaped seat 106, the friction between the locking nut 204 and the surface of the U-shaped seat 106 prevents the stud 205 from rotating freely, and the locking nut 204 tightens the threaded engagement degree of the stud 205 and the U-shaped seat 106 to further prevent the stud 205 from rotating freely.

[0052] The above structure is adopted, specifically in the process of slitting and using the transparent tape, because at the beginning, the support plate 305 is stuck between the matching grooves 304 at the front and rear positions by means of vertical sliding cooperation with the matching grooves 304, and at the same time, the limiting rod 307 is longitudinally slidably cooperated with the limiting hole 309, then at this time, the support plate 305 is vertically slidably cooperated with the matching grooves 304 and the limiting rod 307 is longitudinally slidably cooperated with the limiting hole 309, so that the position height of the support plate 305 can be locked and the axial end of the threaded positioning rod 405 can be supported by the constraint groove 302, and then the constraint groove 302 is used to limit and support the axial end of the threaded positioning rod 405, so that the threaded positioning rod 405 can more stably drive the transparent tape roll to rotate and slit, and specifically when the transparent tape roll is When the roll is constrained and fixed on the outer periphery of the threaded positioning rod 405, it is only necessary to pull the limiting rod 307 out of the limiting hole 309 to make the support plate 305 slide vertically downward along the matching groove 304 to separate the limiting groove 302 from the axial end of the threaded positioning rod 405, thereby facilitating the smooth installation or removal of the transparent tape roll from the axial end of the threaded positioning rod 405, ensuring that the transparent tape roll can be quickly installed during slitting, and at the same time ensuring that the transparent tape roll is quickly detached after slitting. Specifically, in operation, the handles 301 at the front and rear positions are pulled outward at the same time, and the limiting rods 307 are all pulled out of the corresponding limiting holes 309 by the spring 306. After the limiting rods 307 are all pulled out of the limiting holes 309, the support plate 305 is vertically aligned with the matching groove 304. The support plate 305 slides down in a sliding manner. During this process, the constraint groove 302 slides down vertically. Since the distance between the bottom surface of the support plate 305 and the bottom of the matching groove 304 is greater than the vertical groove length of the constraint groove 302, the support plate 305 can drive the constraint groove 302 to slide down to the top below the threaded positioning rod 405, and then the movable limit plate 406 is disengaged from the outer end of the threaded positioning rod 405 by twisting the threaded sleeve 407, and then the transparent tape roll to be cut is installed by coaxially sliding with the outer periphery of the threaded positioning rod 405 until the end face of the transparent tape roll abuts against the fixed limit plate 404, and then the threaded sleeve 407 is installed again by coaxial threaded cooperation with the threaded positioning rod 405 and the threaded sleeve 407 is twisted to drive the movable limit plate 406 to move out of the outer end of the threaded positioning rod 405. When the handle 301 is released, the spring 306 will release the tension state and drive the inner ends of the limit rods 307 to be inserted into the corresponding limit holes 309, so as to complete the support of the constraint groove 302 on the outer ends of the threaded positioning rods 405.Then the spacing between the slitting discs 602 of the roll slitting assembly 6 can be adjusted. During the adjustment, the limiting screw 604 is loosened, and then the sleeve 603 of the roll slitting assembly 6 slides axially along the mounting shaft 601, and the spacing between the plurality of slitting discs 602 can be adjusted and locked by tightening the limiting screw 604, so that the slitting distance of the transparent tape roll can be adjusted. During the adjustment process, the slitting position can be determined by comparing with the fixed transparent tape roll, so that transparent tapes of different widths can be slid by adjusting the spacing between the slitting discs 602, thereby enriching the general use range of the roll slitting assembly 6. At the same time, before the slitting operation, when the roll slitting assembly 6 is assembled between the U-shaped seats 106 When installing, place the installation shaft 601 horizontally between the fixed chuck 208 and the movable chuck 201 and align them coaxially, then turn the locking nut 204 close to the handle 203, and then hold the handle 203 to drive the stud 205 to rotate clockwise, so that the stud 205 can drive the slots 206 of the movable chuck 201 and the fixed chuck 208 to approach and slide horizontally with the plug blocks 207 at both ends of the installation shaft 601 of the roll slitting component 6 through the forward rotation of the stud 205. When the stud 205 rotates forward until the movable chuck 201 and the fixed chuck 208 contact the two ends of the installation shaft 601 respectively, the stud 205 cannot continue to rotate, so keep the stud 205 from rotating and tighten the locking nut 204 on the surface of the U-shaped seat 106, so as to lock the locking nut 204 with the U-shaped seat 1 06 surfaces to prevent the stud 205 from rotating freely, and at the same time, the locking nut 204 is used to tighten the threaded engagement degree of the stud 205 and the U-shaped seat 106 to further prevent the stud 205 from rotating freely, and then the reel slitting assembly 6 can be detachably fixed between the movable chuck 201 and the fixed chuck 208 by bringing the movable chuck 201 and the fixed chuck 208 close to each other, so that the reel slitting assembly 6 and the slitting drive assembly 1 can be detachably combined together, and the fixed combination method of the reel slitting assembly 6 and the slitting drive assembly 1 is simple and easy to operate, which is convenient for slitting the transparent tape reel after the reel slitting assembly 6 and the slitting drive assembly 1 are combined. When the reel slitting assembly 6 needs to be removed, screw it. The locking nut 204 is loosened, and then the screw 205 is reversed counterclockwise to drive the slots 206 of the movable chuck 201 and the fixed chuck 208 to move away from the plug blocks 207 at both ends of the installation shaft 601 of the roll slitting assembly 6 and separate from each other. Then, the movable chuck 201 and the fixed chuck 208 are moved away from each other to separate the roll slitting assembly 6 from between the movable chuck 201 and the fixed chuck 208, so that the roll slitting assembly 6 and the slitting drive assembly 1 can be separated from each other. The method of separating the roll slitting assembly 6 from the slitting drive assembly 1 is simple and easy to operate, which is convenient for regular maintenance after the roll slitting assembly 6 is disassembled from the slitting drive assembly 1. At the same time, since the roll slitting assembly 6 and the slitting drive assembly 1 can be quickly combined and disassembled,After the roll slitting assembly 6 is detached from the slitting drive assembly 1, the slitting turntable 602 can be quickly detached by sliding the sleeve 603 along the installation shaft 601 from the end, and the slitting turntable 602 can be quickly installed by installing the sleeve 603 along the installation shaft 601 from the end, thereby realizing the adjustment of the number of slitting turntables 602 of the roll slitting assembly 6, and slitting transparent tapes of different widths can be obtained by adjusting the number of slitting turntables 602, further enriching the general use range of the roll slitting assembly 6. When it comes to the slitting operation, the cylinder body 104 is connected to the external air supply pipeline and then works, and the drive motor 1 101 and the drive motor 2 401 are respectively electrically connected to the external power supply cable and then work, and the cylinder body 104 is connected to the external power supply cable through the push rod 103. The U-shaped seat 106 and the installation shaft 601 and the slitting turntable 602 of the roll slitting assembly 6 are driven to move forward longitudinally, and the driving motor 101 drives the installation shaft 601 and the slitting turntable 602 of the roll slitting assembly 6 to rotate through the motor shaft 102. At the same time, the driving motor 2 401 drives the threaded positioning rod 405 and the transparent tape roll to be slit to rotate through the motor shaft 2 402. Then, the slitting turntable 602 of the roll slitting assembly 6 can perform a slitting operation on the rotating transparent tape roll by rotating while approaching the transparent tape roll. After the slitting operation is completed, the roll slitting assembly 6 is first moved back longitudinally and stopped rotating, and the threaded positioning rod 405 and the transparent tape roll are also stopped. Then, the slit transparent tape roll is detached from the outer end of the threaded positioning rod 405 according to the above operation method.
