Description

Technical Field

[0001] This invention relates to the technical field of banner cutting machine components, and in particular to a banner cutting assembly. Background Technology

[0002] The banner manufacturing process includes multiple stages such as design, pre-processing, printing, cutting, adhesive backing and folding, pole mounting, packaging, and shipping. The banner cutting assembly is the component that completes the cutting process. There are two existing types of banner cutting assemblies. The first is similar to the patent with authorization announcement number CN212270506U, a hot cutting device for flag banner fabric; this device uses a heating wire to quickly melt and cut the banner fabric. The second is similar to the patent with authorization announcement number CN111453505B, a fully automatic post-processing device for making advertising banners, which discloses a cutting device. This cutting device includes a cutter, a cutter slider, and a cutter motor; when the motor drives the cutter to move back and forth, the guide wheel rotates, causing the cutter wheel to rotate rapidly to achieve the purpose of cutting the banner. Comparatively, the first type of banner cutting assembly has a higher overall cost, but produces relatively clean cuts. The second type, while cheaper, lacks constraint on the banner fabric during cutting, causing slight displacement due to the cutter's pressure. This slight displacement results in uneven cuts when the fabric is further cut, affecting the overall quality of the banner. There is an urgent need in the market for a low-cost banner cutting assembly that produces clean cuts. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a strip cutting component.

[0004] The technical solution of this invention is as follows: A banner cutting assembly includes a reciprocating lateral movement component, a cutting component, and a cutting platform; the cutting platform has a cutting slit; the reciprocating lateral movement component includes a drive motor, a crossbeam disposed above the cutting platform, and a lateral movement mechanism; both the drive motor and the lateral movement mechanism are mounted on the crossbeam; the cutting component is mounted on the output end of the lateral movement mechanism; the drive motor outputs power to drive the cutting component to reciprocate laterally through the lateral movement mechanism; the cutting component includes a cutter, a cutter mounting plate, and a banner constraint frame; the cutter is mounted at the bottom of the cutter mounting plate, extends downward, and corresponds to the cutting slit, for cutting the banner fabric reaching above the cutting slit; the banner constraint frame includes symmetrically arranged components. The cutting platform has horizontal bars on both sides of the front and rear of the cutter, and spring telescopic rods symmetrically arranged on the left and right sides of the cutter mounting plate. Several constraint wheels are arranged horizontally on the horizontal bars and are rotatably connected to the horizontal bars. The constraint wheels abut against the cutting platform. The spring telescopic rod includes a rod body, a mounting base, a spring, a flat washer, a limit screw, and an adjusting screw. The lower end of the rod body is hinged to the end of the horizontal bar, so that the horizontal bar can be tilted appropriately. The banner fabric on the cutting platform is usually printed with patterns or text. These patterns or text will cause some undulations on the surface of the banner fabric. The appropriately tilting horizontal bars can maintain the state of the constraint wheels pressing and constraining the banner fabric even in the undulating parts of the banner fabric. The mounting base includes a connected side plate and a sleeve block; the side plate has a vertical adjustment elongated hole; an adjustment screw passes through the adjustment elongated hole and is threadedly connected to the cutter mounting plate; the sleeve block has a sleeve hole that matches the upper end of the rod; the upper end of the rod passes through the sleeve hole; the lower part of the rod has a step; a spring is fitted in the middle of the rod, with its upper end abutting against the sleeve block and its lower end abutting against the step; the fit between the rod and the sleeve hole provides guidance for the sliding of the rod relative to the sleeve block; the relative movement of the sleeve block and the step compresses the spring; the outer diameter of the flat washer is greater than the inner diameter of the sleeve hole; a limiting screw passes through the flat washer and is threadedly connected to the upper end of the rod; the flat washer is installed on the upper end of the rod by the limiting screw to limit the vertical sliding limit between the rod and the sleeve hole; When the fabric strip reaches the cutting platform, the constraint wheels compress and constrain the fabric strip on both sides of the cutter, providing sufficient limitation and ensuring a flush cut after the cutter moves laterally. The adjustment of the elongated hole and the adjustment screw allows adjustment of the height at both ends of the crossbar, leveling the crossbar. The height difference between the end of the crossbar and the cutting platform determines the compression of the spring when the constraint wheel comes into contact with the cutting platform. The compression of the spring, in turn, determines the compressive force of the constraint wheel on the fabric strip. Therefore, the basic function of the adjustment of the elongated hole and the adjustment screw is to level the crossbar, ensuring that all constraint wheels are in a state of compressing the fabric strip. A further function is to adjust the compressive force of the constraint wheel on the fabric strip.

[0012] Preferably, buffer blocks are provided at both ends of the crossbeam to buffer the cutting component when it moves to its extreme position.

[0013] Preferably, the top of the crossbeam is provided with several photoelectric sensors; the back of the cutter mounting plate is provided with a U-shaped photosensitive film; one end of the photosensitive film is connected to the back of the cutter mounting plate, and the other end is engaged with the photoelectric sensor; the photoelectric sensor is set on the crossbeam at the key position where the cutting part needs to stop; the photosensitive film and the photoelectric sensor work together to enable the cutting part to stop at the key position.

[0019] Example 1: See Figure 1-14A banner cutting assembly includes a reciprocating lateral movement component 1, a cutting component 2, and a cutting platform 3. The cutting platform 3 has a cutting slit 31. The reciprocating lateral movement component 1 includes a drive motor 11, a crossbeam 12 disposed above the cutting platform 3, and a lateral movement mechanism. The drive motor 11 and the lateral movement mechanism are both mounted on the crossbeam 12. The cutting component 2 is mounted on the output end of the lateral movement mechanism. The drive motor 11 outputs power to drive the cutting component 2 to reciprocate laterally through the lateral movement mechanism. The cutting component 2 includes a cutter 21, a cutter mounting plate 22, and a banner constraint frame 23. The cutter 21 is mounted at the bottom of the cutter mounting plate 22, extends downward, and corresponds to the cutting slit 31, for cutting the banner fabric that reaches above the cutting slit 31. The banner constraint frame 23 includes components symmetrically arranged in front of the cutter 21. The horizontal bars 231 on both sides of the back, and the spring telescopic rods 232 symmetrically arranged on the left and right sides of the cutter mounting plate 22; several constraint wheels 2311 are arranged horizontally on the horizontal bars 231 and are rotatably connected to the horizontal bars 231; in this embodiment, there are 5 constraint wheels 2311; the constraint wheels 2311 abut against the cutting platform 3; the spring telescopic rods 2322 include rod body 2321, mounting base 2322, spring 2323, flat washer 2324, limit screw 2325, and adjusting screw 2326; the lower end of the rod body 2321 is hinged to the end of the horizontal bar 231, so that the horizontal bar 231 can be tilted appropriately; the strip cloth on the cutting platform 3 is generally printed with patterns or text; these patterns or text will cause some undulations on the surface of the strip cloth; the horizontal bars 2312 that can be tilted appropriately 1. This ensures that the reciprocating lateral movement of the banner constraint frame 23 maintains the state of the constraint wheel 2311 pressing and constraining the banner fabric even when the banner fabric undulates; the mounting base 2322 includes a connected side plate 23221 and a sleeve block 23222; the side plate 23221 has a vertical adjustment elongated hole 232211; the adjustment screw 2326 passes through the adjustment elongated hole 232211 and is threadedly connected to the cutter mounting plate 22; the sleeve block 23222 has a sleeve hole 232221 that matches the upper end of the rod body 2321; the upper end of the rod body 2321 passes through the sleeve hole 232221; the lower part of the rod body 2321 has a step 23211; the spring 2323 is fitted in the middle of the rod body 2321, with its upper end abutting against the sleeve block 23222 and its lower end abutting against the step 23211; the rod body The fit between 2321 and the sleeve hole 232221 provides guidance for the sliding of the rod 2321 relative to the sleeve block 23222; the relative movement of the sleeve block 23222 and the step 23211 compresses the spring 2323; the outer diameter of the flat washer 2324 is greater than the inner diameter of the sleeve hole 232221; the limiting screw 2325 passes through the flat washer 2324 and is threaded to the upper end of the rod 2321; the flat washer 2324 is installed on the upper end of the rod 2321 through the limiting screw 2325, which limits the vertical sliding limit between the rod 2321 and the sleeve hole 232221; when the strip cloth reaches the cutting platform 3, the constraint wheel 2311 squeezes and constrains the strip cloth on both sides of the front and rear of the cutter 21, which fully limits the movement and makes it easier for the cut after the cutter 21 moves laterally to be flush;The engagement of the adjusting hole 232211 and the adjusting screw 2326 allows for adjustment of the height at both ends of the crossbar 231, thus leveling the crossbar 231. The height difference between the end of the crossbar 231 and the cutting platform 3 determines the compression of the spring 2323 when the constraint wheel 2311 abuts against the cutting platform 3. The compression of the spring 2323, in turn, determines the squeezing force of the constraint wheel 2311 on the fabric. Therefore, the basic function of the engagement of the adjusting hole 232211 and the adjusting screw 2326 is to level the crossbar 231, ensuring that each constraint wheel 2311 is in a state of squeezing the fabric. A further function is to adjust the squeezing force of the constraint wheel 2311 on the fabric.

[0020] Compared with the prior art, the present invention provides a banner cutting assembly that is both inexpensive and produces clean cuts. The banner cutting assembly uses a cutter 21 for cutting, which is inexpensive; the constraint wheels 2311 on both sides of the cutter 21 fully limit the movement of the banner fabric, ensuring that the cut of the cutter 21 is clean.

[0021] The crossbeam 12 is made of aluminum profile; aluminum profile is lightweight and has several grooves on its surface to facilitate the disassembly and installation of various components with bolts.

[0022] The cutter 21 is a paper cutter blade; the paper cutter blade is a professional industrial blade; when the cutting edge at the front end of the blade is no longer sharp, the front end of the paper cutter blade can be broken off and a new front end of the paper cutter blade can be used; therefore, the service life of a single paper cutter blade is much longer than that of an ordinary blade, which can save costs; the lower front of the cutter mounting plate 22 is provided with a cutter groove 221 that matches the cutter 21, a clamping plate 222, and a mounting screw 223; the cutter groove 221 is inclined; the cutter 21 is inserted into the cutter groove 221 and is limited to a certain extent, reducing the loosening of the cutter 21 when it moves laterally; the clamping plate 222 is located on the outside of the cutter groove 221; the mounting screw 223 passes through the clamping plate 222 and is threadedly connected to the cutter mounting plate 22; the clamping plate 222 clamps the cutter 21 to realize the installation of the cutter 21; the mounting screw 223 fixes the clamping plate 222.

[0023] There are two cutters 21, which are symmetrically arranged on the left and right sides of the cutter mounting plate 22, so that the reciprocating cutter 21 can complete the strip fabric cutting task in a single stroke.

[0024] Both cutters 21 extend from the midpoint of the lower edge of the cutter mounting plate 22 to avoid interference between the two cutters 21.

[0025] Four clamping wheels 224 are rotatably connected to the back of the cutter mounting plate 22; two clamping wheels 224 are on top; the other two clamping wheels 224 are on the bottom; the upper clamping wheels 224 and the lower clamping wheels 224 cooperate to clamp the crossbeam 12, providing guidance for the reciprocating lateral movement of the cutter 21.

[0026] A corresponding lower clamping wheel 224 is installed directly below each of the upper clamping wheels 224 to improve the stability of the clamping wheels 224 clamping the crossbeam 12.

[0027] The transverse movement mechanism includes a drive pulley 131, a driven pulley 132, and an annular conveyor belt 133. The annular conveyor belt 133 horizontally surrounds the crossbeam 12 and connects the drive pulley 131 and the driven pulley 132. The drive pulley 131 is coaxially fixed to the output shaft of the drive motor 11. The driven pulley 132 is rotatably connected to the crossbeam 12. The back of the cutter mounting plate 22 is in contact with the front of the annular conveyor belt 133. The drive motor 11 outputs torque and transmits it to the drive pulley 131. The drive pulley 131 and the driven pulley 132 cooperate to make the annular conveyor belt 133 rotate in annular shape. The rotating annular conveyor belt 133 drives the cutting component 2 to move back and forth.

[0028] The reciprocating lateral movement component 1 also includes a tensioning mechanism 14; the tensioning mechanism 14 includes a U-shaped mounting bracket 141, a U-shaped adjusting bracket 142, a wing nut 143, an external pull bolt 144, and a guide screw 145; the adjusting bracket 142 is fitted inside the mounting bracket 141; the driven pulley 132 is rotatably connected inside the adjusting bracket 142; the movement of the adjusting bracket 142 is also the movement of the driven pulley 132; the movement of the driven pulley 132 can tension the annular conveyor belt 133; the mounting bracket 141 has symmetrical transverse elongated holes 1411 on both sides; the open end of the mounting bracket 141 is connected to the side of the end of the crossbeam 12, realizing the connection between the mounting bracket 141 and the crossbeam 12. The crossbeam 12 is connected; the guide screw 145 passes through the transverse elongated hole 1411 and connects with the adjusting frame 142; the pull bolt 144 passes through the closed end of the adjusting frame 142 and the closed end of the mounting frame 141, and is threadedly engaged with the wing nut 143; the wing nut 143 abuts against the closed end of the adjusting frame 142; rotating the wing nut 143 moves the pull bolt 144 axially; the pull bolt 144 acts on the adjusting frame 142, pulling the adjusting frame 142 into the mounting frame 141; during the movement of the adjusting frame 142, the engagement of the guide screw 145 with the transverse elongated hole 1411 provides guidance for the movement of the adjusting frame 142.

[0029] The crossbeam 12 is provided with buffer blocks 121 at both ends to buffer the cutting component 2 when it moves to the limit position; the buffer blocks 121 are installed on the aluminum profile crossbeam 12 with screws.

[0030] The top of the crossbeam 12 is provided with several photoelectric sensors 122; the back of the cutter mounting plate 22 is provided with a U-shaped photosensitive film 123; one end of the photosensitive film 123 is connected to the back of the cutter mounting plate 22, and the other end cooperates with the photoelectric sensor 122; the photoelectric sensor 122 is set on the crossbeam 12 at the key position where the cutting component 2 needs to stop; the photosensitive film 123 cooperates with the photoelectric sensor 122 to enable the cutting component 2 to stop at the key position; there are 3 photoelectric sensors 122 in this embodiment.

[0031] A belt pressing mechanism 124 is provided at the top of the crossbeam 12; the belt pressing mechanism 124 includes a belt pressing plate 1241 and a belt pressing wheel 1242; one end of the belt pressing plate 1241 is detachably connected to the top of the crossbeam 12, and the other end extends rearward and is rotatably connected to the belt pressing wheel 1242; the side of the belt pressing wheel 1242 abuts against the outer side of the annular conveyor belt 133; the belt pressing wheel 1242 squeezes the outer side of the annular conveyor belt 133 to ensure the wrap angle between the annular conveyor belt 133 and the driving pulley 131 and the driven pulley 132, and to ensure the stable flow of the annular conveyor belt 133; the end of the belt pressing plate 1241 is detachably installed on the aluminum profile crossbeam 12 by screws.

[0032] The end of the cutting slit 31 is provided with an outwardly extending rest plate 32; the rest plate 32 is generally in the shape of an inverted "Z"; the midpoint of the rest plate 32 is provided with a groove 321 aligned with the cutting slit 31; when the cutting component 2 moves to the end of the cutting slit 31, the elastic potential energy of the spring 2323 is released, thus allowing it to rest; the service life of the spring 2323 is increased.

[0033] There are two stop plates 32, which are symmetrically arranged at the left and right ends of the cutting slit 31, so that both ends of the cutting slit 31 have a stop point for the spring 2323 to rest.

[0034] The working process of this embodiment includes the following processes: ①The banner fabric is conveyed to the cutting platform 3 The banner fabric is driven forward, beyond the cutting slit 31 of the cutting platform 3; at this time, the cutting component 2 stops above a stop plate 32; ② Cutting component 2 performs single-pass cutting. The drive motor 11 outputs torque, which drives the annular conveyor belt 133 to move through the active pulley 131 and the passive pulley 132. The annular conveyor belt 133 carries the cutting component 2 to another stop plate 32. During the one-way lateral movement of the cutting component 2, the constraint wheel 2311 abuts against the strip fabric, fully limiting the strip fabric on the front and rear sides of the cutter 21. Furthermore, the cutting edge of the cutter 21 corresponds to the midpoint of the horizontal strip 231, so the strip fabric is already squeezed and constrained by the constraint wheel 2311 before the blade cuts the strip fabric. After the blade cuts the strip fabric, the strip fabric does not immediately lose the squeeze and constraint. The cut formed by the cutter 21 on the strip fabric is relatively neat. ③ The banner fabric has been cut. The cutting component 2 reaches above another stop plate 32; the constraint wheel 2311 no longer squeezes the constraint strip cloth and is in a relatively free state; the elastic potential energy accumulated in the spring 2323 is released, which can improve the service life of the spring 2323.

[0035] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The differences are as follows: A lifting pad 33 and a U-shaped support plate 34 are provided below the cutting seam 31; lifting seats 35 are symmetrically provided at both ends of the lifting pad 33; the closed end of the U-shaped support plate 34 faces upward and is set between the lifting pad 33 and the lifting seat plate 35; the length of the U-shaped support plate 34 matches the length of the cutting seam 31; the lifting seat plate 35 includes a lifting screw 351, a connected horizontal plate 352 and a vertical plate 353; the horizontal plate 352 is connected to the open end of the U-shaped support plate 34; the vertical plate 353 is provided with a vertical elongated hole 3531; the lifting screw 351 passes through the vertical elongated hole 3531 and is threaded into the side wall of the cutting platform 3; the lifting pad 33 can be raised and lowered by the cooperation of the lifting screw 351 and the vertical elongated hole 3531; the U-shaped support plate 34 strengthens the support effect of the lifting seat plate 35 on the pad; the height adjustment of the lifting pad 33 is to adapt to the cutting depth of the cutter 21.

[0036] The engagement of the lifting screw 351 with the vertical elongated hole 3531 only allows for approximate adjustment of the lifting pad 33. Therefore, the lifting pad 33 is also symmetrically equipped with height adjustment bolts 354 at both ends. The height adjustment bolts 354 are threaded into the horizontal plate 352. The end of the height adjustment bolts 354 abuts against the closed end of the U-shaped support plate 34. The height adjustment bolts 354 can make more precise adjustments to the end of the lifting pad 33. Rotating the height adjustment bolts 354 causes the end of the height adjustment bolts 354 to extend or retract relative to the horizontal plate 352, thereby changing the height of the end of the U-shaped support plate 34 and the height of the lifting pad 33.
