Abstract
Description
Technical Field
[0001] This utility model relates to the field of tape application auxiliary equipment technology, and in particular to a tape roll slitting machine with adjustable blade spacing. Background Technology
[0002] In tape production applications, such as the frame sealing tape used in the production and assembly of solar panels, the tape used to bond components in the production of electrical equipment, and the tape that is bonded to the outside of the product to protect it during transportation, etc., large rolls of tape need to be cut into smaller rolls of tape of different widths to facilitate subsequent use (the adhesive layer of the tape has a release film at one end) and storage (for example, the finished width of the solar panel frame sealing tape roll is 50 cm, but the actual width of the frame sealing tape used for installation is 5 cm, so it needs to be cut).
[0003] While existing tape slitting machines can cut large rolls of tape, their structural limitations present several technical challenges. Specifically, they typically employ only a single electric cutter. During operation, a PLC or host computer controls an electric linear slide to reciprocate the cutter. The electric cutter, aided by an electric push rod, then slits the tape roll into smaller segments. This reciprocating motion, which cuts only one segment at a time, results in low efficiency. Utility Model Content
[0004] This utility model provides a tape roll slitting machine with adjustable blade spacing that can easily fix a large roll of tape to be slit into place, and under the joint action of related mechanisms, can simultaneously slit the large roll of tape into smaller rolls of tape and rewind them in one go. After slitting, multiple small rolls of tape can be easily removed, thereby improving work efficiency.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A tape roll slitting machine with adjustable blade spacing includes a fixed base, a base plate, electric push rods, a cutting shaft, cutting blades, a motor, and guide rollers. Its distinguishing feature is that it also includes an electric winding mechanism. The fixed base has at least two sets, each with a fixing groove at its upper end, and the two sets are respectively mounted on one side of the base plate. Multiple support rods are mounted on the middle of the base plate, each with a guide groove. A fixing plate is mounted on the upper end of each support rod. The electric push rod has at least two sets, with its upper ends respectively mounted on the front and rear ends of the lower end of the fixing plate. Multiple cutting blades are installed at intervals on the outer end of the cutting shaft, and the front and rear ends of the cutting shaft are rotatably mounted on the lower ends of the two sets of electric push rods. One end of the cutting shaft is connected to the motor shaft. The guide rollers have at least two sets, with the two sets positioned front and rear respectively. The components are distributed and installed in guide slots of multiple support rods; the electric winding mechanism includes a motor reducer, a winding drum, and a fixing slot. Bearing seats are installed at the front and rear of the other side of the base plate, and a shaft is rotatably installed in each bearing seat. The upper end of the fixing slot is an open structure with fixing holes. The outer sides of the two fixing slots are respectively installed on the inner sides of the two shafts. The rotating shaft of the motor reducer and the outer side of one of the shafts are installed together; there are multiple sets of winding drums, and a paper tube is fitted on the outer side of each set of winding drums. The surface of the paper tube has multiple tear lines spaced at intervals; connecting shafts are installed on the front and rear sides of the winding drum, and the connecting shafts have fixing holes A. The connecting shafts at the front and rear ends of the winding drum are respectively fitted into the two fixing slots from top to bottom, and bolts pass through the fixing holes of the fixing slots and the fixing holes A of the connecting shafts to install the fixing slots and connecting shafts together.
[0007] Furthermore, the lower ends of the two sets of guide rollers are at the same height.
[0008] Furthermore, the spacing between every two cutting blades in the plurality of cutting blades is consistent with the width of the small rolls of tape that need to be rolled.
[0009] Furthermore, the front-to-back length of the guide roller, cutting shaft, and winding drum is greater than the width of the large roll of tape.
[0010] Furthermore, the outer diameter of the connecting shaft of the winding drum is smaller than the inner diameter of the fixed frame.
[0011] Furthermore, the inner diameter of the paper tube in each set of take-up reels is larger than the outer diameter of the take-up reel.
[0012] Furthermore, two magnetic rings are attracted to each side of the winding drum.
[0013] The beneficial effects of this utility model are as follows: Before slitting, the two sides of the shaft of the large roll of tape to be slitted are rotated and fitted into the fixing grooves at the upper end of the two fixing seats. Then, it is led out from the lower end of the two guide rollers and wound around the take-up drum one or two times. Specifically, in order to facilitate the removal of multiple small rolls of tape after slitting, a small section of tape wrapped around the take-up drum and between the tape and the right guide roller can be pre-cut with scissors, dicing blades, etc., at appropriate distances (consistent with the spacing of multiple tear lines), and several horizontal cuts (the rightmost 1 cm or so is not separated, so that it can be easily wound onto the take-up drum). During operation, the motor can synchronously drive multiple slitting blades to rotate, and the large roll of tape can be slitted into small rolls of tape and wound up at one time. After slitting, it is easy to remove multiple small rolls of tape, which improves work efficiency accordingly. Attached Figure Description

[0018] Figure 1 , 2As shown in Figures 3 and 4, the tape roll slitting machine with adjustable blade spacing includes a fixed base 1, a base plate 2, an electric push rod M1, a cutting shaft 3, a cutting blade 4, a motor M2, a power module W1, a power switch, a guide roller 5, and an electric winding mechanism 6. There are two sets of fixed bases 1, each with a fixing groove 101 in the middle of its upper end. The lower ends of the two fixed bases 1 are respectively mounted on the front and rear left sides of the base plate 2. The rotating shaft 71 of the large tape roll 7 to be slitted is rotatably fitted into the fixing grooves 101 on the upper ends of the two fixed bases on both sides. (After slitting, the rotating shaft of the slitted tape roll is removed and placed in the fixed base.) A new set of large rolls of adhesive tape is placed in the groove. Four support rods 21 are welded at intervals on the left and right sides of the front and rear ends of the middle section of the base plate 2. Each support rod 21 has a vertically distributed guide groove 22 in its middle. A rectangular fixing plate 23 is welded to the upper end of the four support rods. There are two sets of electric push rods M1. The upper ends of the cylinders of the two sets of electric push rods M1 are vertically distributed and bolted to the middle of the front and rear sides of the lower end of the fixing plate 23. There are multiple cutting blades 4. Each cutting blade 4 has an internal thread seat in its middle. The cutting shaft 2 has external threads. The multiple cutting blades 4 are screwed into the outside of the cutting shaft 2 through the internal thread seats, and then spaced back and forth. The distance is installed on the outer end of the cutting shaft 2 (the tape roll can be cut into different widths by adjusting the spacing of multiple cutting blades). Two nuts 41 are screwed into and fixed on the front and rear sides of each cutting blade 4. The front and rear ends of the cutting shaft 2 are respectively tightly fitted into the inner ring of a bearing seat 42. The upper ends of the two bearing seats 42 are respectively bolted to the lower ends of the push columns of two sets of electric push rods M1. The rear end of the cutting shaft 3 is located outside the rear bearing seat and is bolted to the rotating shaft of the motor M2 via a flange. A support plate 8 is longitudinally welded to the lower end of the rear bearing seat. The lower end of the motor M2 housing The guide rollers are bolted to the support plate 8. There are two sets of guide rollers 5. Each set of guide rollers 5 has a bearing 51 tightly fitted at the front and rear ends of its inner side. A fixing rod 52 is tightly fitted at the front and rear of the inner ring of the two bearings 51 of each set of guide rollers. The front and rear ends of the fixing rod 52 have external threads. The fixing rods 52 of the two sets of guide rollers are located in the guide grooves 22 of the two support rods distributed at the front and rear of the left end and the right end, respectively (the height of the guide rollers can be adjusted up and down so that the lower end can effectively fit the upper end of the tape). The front and rear ends of the two fixing rods 52 are screwed into a nut and fixed between the front and rear parts of the two support rods 21 at the left end and the two support rods 21 at the right end.The electric winding mechanism includes a motor reducer M3, a winding drum 61 (made of steel), and rectangular fixing slots 62. A set of bearing seats 63 is bolted to the front and rear of the right side of the base plate 2. Each bearing seat 63 has a shaft 64 tightly fitted inside its inner ring. The upper end of the fixing slot 62 is an open structure with a through fixing hole 621 in the middle of its left and right ends. The outer sides of the front and rear ends of the two fixing slots 62 are welded to the inner sides of the two shafts 64, respectively. The motor reducer M3 is bolted to the front right end of the base plate 2, and the rear end of the motor reducer M3's shaft is welded to the front side of one of the front shafts 64 (located on the front outer side of the front bearing seat). Multiple sets of winding drums 61 are included, with one shaft of equal length fitted onto the outer side of each set. A paper tube 65 with uniform thickness has multiple tear lines 66 on its surface at intervals (the surface of the paper tube 65 is formed by openings at regular intervals); a rectangular connecting shaft 67 is welded to the middle of the front and rear sides of the take-up drum 61, and a through fixing hole A68 is respectively found at the middle of the left and right ends of the two connecting shafts 67. The connecting shafts 67 at the front and rear ends of the take-up drum 61 are respectively fitted into two fixing grooves 62 from top to bottom, and two bolts 69 are passed through the fixing holes 621 at the front end of the two fixing grooves, the fixing holes A68 of the two connecting shafts, and the fixing holes 621 at the rear end of the two fixing grooves, respectively. A nut is screwed into the right end of each of the two bolts 69 to fix the two connecting shafts 67 of the take-up drum into the two fixing grooves 62 respectively. The power module W1 and the power switch and power switch A are installed in the component box 9, which is installed on the upper left front side of the base plate. The upper end of the take-up drum is higher than the lower end of the guide roller. A wooden support platform 11 is installed on the base plate between the lower ends of the four support rods 21.
[0019] Figure 1 , 2As shown in Figures 3 and 4, the distance between the outer sides of the rotating parts at the front and rear ends of the guide roller 5 and the inner sides of the two support rods 21 is equal, and the lower ends of the two guide rollers 5 are at the same height. The spacing of the multiple cutting blades 4 is the same as the width of the small rolls of tape to be split. The front-to-back length of the guide roller 5, the cutting shaft 3, and the winding drum 61 is greater than the front-to-back width of the large roll of tape 7. The outer diameter of the connecting shaft 67 of the winding drum is slightly smaller than the inner diameter of the fixed frame 62, and the inner diameter of the paper tube 65 of each winding drum is slightly larger than the outer diameter of the winding drum 61 by 0.5 mm (to facilitate insertion into the outer side of the winding drum 61). The spacing between every two easy-tear lines 66 on the paper tube is the same as the front-to-back width of the small rolls of tape after splitting. Two annular hollow magnet rings 10 (with an outer diameter larger than the outer diameter of the winding drum, limiting the outer side of the small rolls of tape being wound) are attracted to both sides of the winding drum, and the distance between the outer sides of the front and rear ends of the two magnet rings 10 and the inner side of the fixed frame 62 is equal. The power input terminals 1 and 2 of power module W1; the power input terminal of motor M2 is connected in series with the first power switch AS1, and the power input terminal of motor reducer M3 is connected in series with the second power switch AS2, and the two AC 220V power supply terminals are connected by wires respectively. The power output terminals 3 and 4 of power module W1 and the power input terminals 1 and 2 of power switch S3 are connected by wires respectively, and the power output terminals 3, 4, 5, and 6 of power switch S3 are connected by wires to the positive and negative and negative-positive power input terminals of electric actuator M1. The handles of the three power switches are located outside the opening at the front of the component box.
[0020] Figure 1 , 2As shown in Figures 3 and 4, after the 220V power supply enters the power input terminal of the power module W1, the power module W1 outputs a stable DC 24V power supply through pins 3 and 4, which enters the power input terminal of the power switch S3. Before slitting, the shaft 71 of the large tape roll 7 to be slitted is rotated and fitted into the fixing grooves 101 at the upper end of the two fixing seats on both sides. Then, it is led out from the lower end of the two guide rollers 5 to the right end and wound around the take-up drum 61 once or twice (the tape is straightened). Specifically, in order to facilitate the removal of multiple small tape rolls after slitting, a small section of tape wrapped around the take-up drum 61 and between it and the right end guide roller 5 can be pre-cut horizontally at appropriate intervals (consistent with the spacing of multiple tear lines) using scissors or a slicing blade. The rightmost 1 cm or so is not separated so that it can be wound around the take-up drum. The 1 cm length will not cause resistance to the worker pulling the slitted small tape rolls forward, and the 1 cm length of tape can be easily broken. During operation, when the operator turns on the power switch AS1, the motor M2 is energized and its shaft drives multiple cutting blades 4 to rotate clockwise. When the handle of the power switch S3 is moved to the left, pins 1 and 2 and pins 3 and 4 of the power switch S3 are connected respectively, and the positive and negative power input terminals of the two sets of electric push rods M1 are energized. Their push rods push the rotating cutting blades 4 downward. When the lower end of the cutting blades 4 is fully in contact and straightened, the tape roll closes the power switch S3, and then the multiple cutting blades 4 can divide the tape roll into multiple strips in the longitudinal direction (which are then wound into multiple small rolls of tape). When the power switch AS2 is turned on, the motor reducer M3 drives the winding drum 61 to rotate clockwise through the fixed frame 62 to wind up the slit tape. After subsequent rolls are completed, when the handle of power switch S3 is turned to the right, pins 1 and 2 and pins 5 and 6 of power switch S3 are connected respectively. The positive and negative power input terminals of the two sets of electric push rods M1 are energized, and their push rods drive the rotating cutting blade 4 to move up a certain distance to turn off power switch S3 (and turn off power switch AS1, the cutting blade 4 stops rotating, and turn off power switch AS2. The motor reducer M3 is de-energized). Then, the worker unscrews the bolts of the fixing frame 62 and the connecting shaft 67, and removes the take-up drum upwards (to facilitate the removal of the take-up drum, when the opening of the fixing frame is rotated to the top, the power switch of the motor reducer is turned off). Then, the new take-up drum is fixed in the two fixing frames with bolts, and the next large roll of tape 7 can be cut and wound up. After removing the rewinding roll, the worker removes the permanent magnet rings 10 at both ends (the middle part is a hollow annular structure), and then pulls the multiple small rolls of tape forward from back to front. This makes it easy to remove the smaller rolls of tape after slitting (the easy-tear line 66 of the corresponding section of the paper tube 65 will break when pulled, making it easy to remove the corresponding section of the small roll of tape). This new type of tape can simultaneously slit a large roll of tape into smaller rolls and rewind them in one go, and the multiple small rolls of tape can be easily removed after slitting, thus improving work efficiency.In this invention, the upper end of the take-up drum 61 is higher than the lower end of the guide roller 5, so the tape can be straightened and cut (the rotation of the guide roller 5 serves to limit and guide the tape); since a wooden support platform 11 is installed between the lower ends of the four support rods 21, the tape can be restricted between the lower end of the guide roller and the upper end of the support platform, which facilitates cutting (because the support platform is made of wood, even if the cutting blade contacts its upper end, it will not cause damage to the blade).
