Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment for tape application, and in particular to a tape slitting machine. Background Technology
[0002] In various applications of adhesive tape, such as the sealing tape used for the frame assembly of solar panels (longer sealing tapes are generally about 1m in length and 4mm in width, but the actual length and width vary depending on the specific product being manufactured; the adhesive surface at the bottom of the sealing tape has a release film protective layer), the tape used for bonding components in the production of electrical equipment, and the tape used to bond the outside of products to protect them during transportation, etc., it is necessary to cut large rolls of finished tape into several smaller segments of appropriate length as needed to meet actual production requirements.
[0003] Existing tape roll slitting methods typically involve a worker inserting a horizontally distributed spindle (or, if the tape roll lacks a spindle) into the inner part of the roll, with both ends fitted onto a rotating base. The worker then pulls out a section of tape and manually cuts it with scissors or a slitting blade. While this method meets some work requirements, it suffers from structural limitations and several technical problems. First, manual cutting of the tape by hand becomes inconvenient over time, hindering efficiency and increasing production costs. Second, manual cutting with blades or scissors can lead to inconsistencies, such as insufficient experience or misalignment, resulting in a non-straight cut. This affects the tape's appearance and may negatively impact end-use applications (e.g., excessive curvature, leaving gaps that hinder effective bonding and sealing). Therefore, a convenient and effective tape roll slitting device is essential. Utility Model Content
[0004] This utility model provides a tape slitting machine that can easily fix the tape roll to be slit into place. With the joint action of related mechanisms, the operator can press the front and rear ends of the tape section to be slit with a one-button power switch to prevent tape displacement and automatically slit the tape section laterally. This not only brings convenience to the operator but also prevents the tape from bending and not being in a straight line after slitting. It overcomes the inconvenience, low work efficiency, and increased production costs caused by the existing technology of manually slitting tape rolls with tools, as well as the inability to guarantee that the tape is in a straight line after slitting, which affects the appearance of the tape and has adverse effects on the end application.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A tape slitting machine includes a fixed base, a base plate, an electric cutter, an electric push rod, an electric linear slide, an upper fixed plate, and a support shell. Its distinguishing feature is that it also includes a control mechanism. The fixed base consists of at least two sets, each with a fixing groove at its upper end. The lower ends of the two fixed bases are respectively mounted on opposite ends of one side of the base plate. The two sides of the tape roll's rotating shaft are rotatably fitted into the fixing grooves at the upper ends of the two fixed bases. Multiple sets of electric push rods are included, with their lower ends mounted on the other side of the base plate. The lower end of the upper fixed plate is mounted on the upper ends of the multiple sets of electric push rods. The electric linear slide is mounted on the lower end of the upper fixed plate. The upper end of another set of electric push rods is mounted on the lower end of the sliding block of the electric linear slide. The electric cutter is mounted on the lower end of another set of electric push rods. The control mechanism is mounted in a component box. The support shell is mounted on the base plate between the multiple sets of electric push rods. The power output terminal of the control mechanism is electrically connected to the power input terminals of the multiple sets of electric push rods, the electric linear slide, and the electric cutter.
[0007] Furthermore, the upper end of the support shell has a cutting groove, and the cutting groove and the cutting blade of the electric cutting machine are on the same vertical plane.
[0008] Furthermore, the width of the cutting groove in the support shell is greater than the thickness of the cutting blade.
[0009] Furthermore, positioning plates are respectively installed on both sides of the lower end of the upper fixing plate, and the width of the positioning plates is greater than the width of the tape roll.
[0010] Furthermore, the control mechanism includes seven sets of time control modules and relays that are electrically connected. The power input terminals of the seven sets of time control modules are connected respectively, and the power output terminal of the seventh set of time control modules and the power input terminals of the relays are connected respectively.
[0011] Furthermore, the seven time control modules can also be replaced by one of the following: PLC, host computer, or microcontroller module.
[0012] The beneficial effects of this utility model are as follows: This new model allows for convenient rotation of both sides of the tape roll to be cut into the fixing grooves at the upper end of two sets of fixing seats. Then, the front end of the tape roll is led out to the right through the lower ends of the two fixing plates. Each time the tape roll reaches the cutting position, the operator only needs to turn on the power switch to press the front and rear ends of the section of tape to be cut, preventing tape displacement during cutting. The electric cutting machine then automatically cuts the section of tape laterally, providing convenience for the operator and preventing the tape from bending and not being in a straight line after cutting. This new model effectively overcomes the drawbacks of existing technology, which involves manually cutting tape rolls with tools, causing inconvenience to operators, hindering work efficiency, increasing production costs, and failing to guarantee that the cut tape is in a straight line, affecting the aesthetics of the cut tape and negatively impacting end-use applications.

[0015] Figure 2 This is the circuit diagram of this utility model. Detailed Implementation
[0016] Figure 1 , 2As shown, the tape slitting machine includes a power module W1, a fixed base 1, a base plate 2, an electric cutter M4, electric push rods M1 and M2, an electric linear slide M3, an upper fixed plate 3, a support shell 4, and a control mechanism 5. There are two sets of fixed bases 1, each with a recessed circular fixing groove 101 (open structure at the upper end) in the middle of its upper end. The lower ends of the two fixed bases 1 are respectively horizontally welded to the front and rear parts of the left side of the base plate 2. The rotating shafts 61 horizontally distributed in the middle of the tape roll 6 (either horizontally distributed in the middle of the tape roll or inserted inside the tape roll without a rotating shaft) are respectively rotated from top to bottom within the fixing grooves 101 at the upper ends of the two sets of fixed bases. There are five sets of electric push rods, four of which have their lower ends... The upper fixing plate 3 is bolted to the upper center of the base plate 2. The lower center of the upper fixing plate 3 is welded to the upper ends of the push columns of the four sets of electric push rods M1. The upper end of the housing of the electric linear slide table M3 is bolted to the lower center of the upper fixing plate 3 with its sliding block facing downward. The upper end of the cylinder of the fifth set of electric push rods M2 is bolted to the lower end of the sliding block of the electric linear slide table M3. The upper center of the housing of the electric cutting machine M4 is bolted to the lower end of the push column of the fifth set of electric push rods M2, and the cutting blade 7 of the electric cutting machine M4 is longitudinally located on the left side. The power module W1, power switch S, and control mechanism 5 are installed in the component box 8, which is installed on the right front side of the base plate 2. The support shell 4 is installed on the middle of the base plate 2 between the four sets of electric push rods M1.
[0017] Figure 1 , 2As shown, the upper center of the support shell 4 has a recessed rectangular cutting groove 41, and the middle of the cutting groove 41 and the lower end of the cutting blade 7 of the electric cutting machine are on the same vertical plane. The width of the cutting groove 41 of the support shell is slightly greater than the thickness of the cutting blade 7, and the forward and backward travel of the sliding block of the electric linear slide M3 is slightly less than the forward and backward width of the tape roll 6. A rectangular positioning plate 31 is welded to the left and right sides of the lower end of the upper fixing plate 3, and the forward and backward width of the positioning plate 31 is slightly greater than the width of the tape roll 6. When the push column of the fifth set of electric push rods M2 is at the lower stop point, the lower end of the cutting blade 7 is located at the upper end of the cutting groove 41. The control mechanism includes seven time control modules W2, W3, W4, W5, W6, W7, and W8 connected via circuit board wiring, and relay K1. The power input terminals 1 and 2 of the seven time control modules W2, W3, W4, W5, W6, W7, and W8 are connected respectively. The power output terminals 3 and 4 of the seventh time control module W8 are connected to the power input terminals of relay K1 respectively. The seven time control modules can also be replaced by a PLC, a host computer, or a microcontroller module. The power input terminals 1 and 2 of power module W1, the two control power input terminals of relay K1 in the control mechanism, and the two poles of the 220V AC power supply are connected by wires. The power output terminals 3 and 4 of power module W1 are connected in series with the power switch S (the handle is located on the front outer end of the component box) and the power input terminals 1 and 2 of the time control module W2 in the control mechanism via wires. Pins 3 and 4 of timing modules W2 and W3 are connected to the positive and negative, and negative-positive power input terminals of four sets of electric actuators M1, respectively, via wires. Pins 3 and 4 of timing modules W4 and W5 are connected to the positive and negative, and negative-positive power input terminals of the fifth set of electric actuators M2, respectively, via wires. Pins 3 and 4 of timing modules W6 and W7 are connected to the positive and negative, and negative-positive power input terminals of the electric linear slide M3, respectively, via wires. The two normally open contacts of relay K1 are connected to the power input terminal of the electric cutting machine M4 via wires.
[0018] Figure 1 , 2As shown, after the AC 220V power supply enters the power input terminal of the power module W1, the 3rd and 4th pins of the power module W1 output a stable DC 24V power supply which enters the power input terminal of the control mechanism. The working process of this new type is as follows: (1) Before specifically cutting the tape roll 6, the operator uses his hand to rotate the front and rear sides of the tape roll shaft 61 to be cut from top to bottom into the fixing groove 101 at the upper end of the two sets of fixing seats. Then, the right end of the tape roll 6 (the front side of the relative position) passes through the lower end of the two positioning plates 31 and leads out to the right (the operator pulls the right end of the tape roll with his right hand). When the right end of the tape roll reaches the position to be cut (the scale value can be marked on the bottom plate between the lower right end of the cutting groove 41 and the electric push rod at the front right end of the bottom plate, and the operator can refer to the scale value to understand whether the position to be cut of the tape roll is at the lower end of the cutting blade 7 and the upper end of the cutting groove 41), after the lower end of the cutting blade 7, the operator presses the button of the power switch S. The power switch S is turned on, and the seven sets of time control modules are powered on and put into operation. (2) After the time control module W2 is powered on, its pins 3 and 4 output a 1.5-second positive and negative power input terminal to the positive and negative power input terminals of the four sets of electric push rods M1. The push rods of the four sets of electric push rods M1 drive the two positioning plates 31 to move down to the stop point. The lower ends of the two positioning plates 31 press the left and right ends of the tape roll cutting point tightly to prevent the tape 6 from shifting during subsequent cutting. (3) After the time control module W4 is powered on, its pins 3 and 4 output power for 2 seconds at intervals of 1.5 seconds to the positive and negative power input terminals of the electric push rod M2. The push rod of the electric push rod M2 drives the electric cutter M4 to descend to the stop point. The lower end of the cutting blade is located at the front end of the tape cutting position. (At the same time that the time control module W4 outputs power at its pins 3 and 4, the time control module W8 will output power for 6 seconds to the power input terminal of the relay K1. The relay K1 is powered on and its control power input terminal and normally open contact terminal are closed. The electric cutter M4 is powered on and cuts the tape.) (4) After the power output of pins 3 and 4 of the time control module W4 stops, the power output of pins 3 and 4 of the time control module W6 is 6 seconds. The positive and negative power input terminals of the electric linear slide M3 are connected. The sliding block of the electric linear slide M3 drives the electric cutter M4 to move from front to back. The cutting blade of the electric cutter M4 cuts the tape roll at the corresponding position (after cutting, there is a connection point about one millimeter long on each side of the tape at the cutting point, which makes it convenient for the staff to continue to pull the tape roll backward. The staff can tear and cut the tape by applying a little force with their hands). The tape is cut at the cutting point.(5) After cutting, the power output of pins 3 and 4 of the time control module W8 stops, the relay K1 is de-energized, and the electric cutter M4 stops working. After the power output of pins 3 and 4 of the time control module W6 stops, the power input of pins 3 and 4 of the time control module W3 outputs a 1.5-second negative and positive power input to the negative and positive power input of the four sets of electric push rods M1. The push rods of the four sets of electric push rods M1 drive the two fixed plates 31 to move up to the stop point. The lower ends of the two positioning plates 31 no longer press down the left and right ends of the tape roll cutting point, preparing for the subsequent cutting of the next section of tape. At the same time as the power output of pins 3 and 4 of the time control module W3, the power input of pins 3 and 4 of the time control module W5 outputs a 2-second negative and positive power input to the negative and positive power input of the electric push rod M2. The push rod of the electric push rod M2 drives the electric cutter M4 to move up to the stop point. The lower end of the cutting blade separates from the tape roll, preparing for the cutting of the next section of tape. (6) One second after the power is output from pins 3 and 4 of the time control module W5, the power is output from pins 3 and 4 of the time control module W7 for 6 seconds. The negative and positive power input terminals of the electric linear slide M3 are connected, and the sliding block of the electric linear slide M3 drives the electric cutter M4 to move from back to front. The electric cutter M4 returns to the initial position at the front to prepare for the next tape cutting (the power switch is turned off at this time). (7) The worker continues to pull the tape to the right after cutting. When the tape roll reaches the lower end of the cutting blade at the next cutting point, the worker can cut the next section of tape again according to the same process as steps (1)-(6) (the worker can easily tear the sides of the cut tape section afterward). After a roll of tape is cut, the worker removes the spool of the tape roll. Figure 2 In this system, relay J1 is a DC24V relay; power module A1 is a finished product of AC 220V to DC 24V switching power supply module; electric actuators M1 and M2 are finished products of 30W reciprocating electric telescopic rods; electric linear slide M3 is a finished product of 50W electric lead screw slide; electric cutting machine M4 has a power of 500W (with toothed blades driven by a motor); time control modules W2, W3, W4, W5, W6, W7, and W8 are finished products of Delixi brand, model KG316 time control switches, which have two power input terminals, two power output terminals, and seven setting buttons.
