Description

Technical Field

[0001] This invention relates to tape slitting equipment, and more specifically, to a tape slitting machine that assists in slitting. Background Technology

[0002] With the widespread application of adhesive tape in industrial, medical, and daily consumer fields, the requirements for tape slitting accuracy, efficiency, and cutting quality are increasing. During the tape slitting process, the heat generated by cutting friction can easily cause the adhesive at the cut edge to melt and re-adhere, resulting in slitting failure or uneven cut surfaces, seriously affecting product quality and subsequent use. Furthermore, traditional slitting machines often use fixed blades and rigid rollers, making it difficult to effectively separate and cool the cut tape segments at the moment of slitting, thus limiting the development of high-efficiency, high-quality slitting processes. A tape slitting machine with publication number CN115744402B is described. This patent improves operational safety by setting a retractable blade frame and a threaded rod drive structure to achieve safe storage and precise extension and retraction of the blades. However, this technical solution only focuses on the mechanical motion control and safety protection of the blades, without addressing the thermal management of the tape during the slitting process, nor providing any measures to prevent the adhesive from melting and sticking together due to high temperatures. Therefore, in high-speed or continuous slitting operations, defects such as cut adhesion and incomplete separation still exist, affecting the yield and cut surface quality. A slitting mechanism for a tape slitting machine, published in CN106276380A, proposes an air inlet pipe connected to a cooling fan inside the blade holder. By introducing cold air into the blade holder cavity, the temperature of the cutting blade is reduced, thereby improving cutting accuracy. Although this solution introduces a cooling mechanism, it only cools the blade itself; the cold air does not directly act on the tape's slitting surface, and it lacks physical separation assistance for the tape body at the moment of slitting. Therefore, it cannot effectively solve the problem of adhesive layer re-adhesion caused by residual heat after tape slitting, nor can it ensure that the slid tape immediately forms a clear and independent slitting gap after cutting. These problems indicate that existing tape slitting machines still have significant shortcomings in slitting assistance, thermal management, and slitting isolation, making it difficult to meet the process requirements of high-precision, high-cleanliness tape slitting. Therefore, the present invention provides a tape slitting machine with auxiliary cutting. By setting a cutting roller with a separating elastic element and a hollow air outlet structure, the elastic element is compressed during tape installation to achieve overall support, and the elastic force is released at the moment of cutting to form a cutting gap. At the same time, gas is introduced to quickly cool the cutting surface, effectively preventing the adhesive from melting and sticking together, and significantly improving the cutting quality and production efficiency. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a tape slitting machine for auxiliary cutting.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A tape slitting machine with auxiliary cutting function includes a slitting actuator and a tape mounting mechanism;

[0006] The slitting execution mechanism includes a moving component and a slitting execution component. The slitting execution component is disposed on the moving component and moves under the drive of the moving component. The slitting execution component includes a drive execution motor and a plurality of execution cutters. The drive execution motor is used to drive the execution cutters to work in order to slitting the tubular tape.

[0007] The tape mounting mechanism includes a rotating assembly, a roller clamping assembly, and a plurality of breaking rollers. The rotating assembly includes a rotating drive unit for driving the breaking rollers to rotate, and the roller clamping assembly for clamping the breaking rollers.

[0008] The slitting roller includes a hollow roller body and a plurality of slitting sleeves. A separating elastic element is provided between the slitting sleeves to provide elastic force, thereby creating a slitting gap between the sleeves. When the tubular tape is mounted on the slitting roller, the separating elastic element is compressed to cause the slitting sleeves to abut against each other. The length of the slitting sleeve matches the cutting length. A plurality of air vents are provided on the hollow roller body.

[0009] The tape installation mechanism further includes an air inlet assembly, which includes an air inlet end and several air outlet ends. The air inlet end is used to connect to an air source, and each of the air outlet ends is connected to a hollow roller body.

[0010] Furthermore, the separating elastic element includes elastic protrusions evenly distributed around the circumference of the separating sleeve. The design of the separating elastic element avoids obstructing the heat dissipation gas, ensuring the separation effect while maintaining a relatively simple design and ensuring normal gas overflow from the outlet groove.

[0011] Furthermore, a pin structure is provided between the separating sleeves to restrict the relative rotation between them. This ensures that the separating sleeves move axially under the elastic force of the separating elastic element, guaranteeing the separation effect achieved by the elastic protrusions through mutual abutment.

[0012] Furthermore, the system also includes a controller and sensing components. The sensing components include a temperature detection unit and a pressure detection unit. The temperature detection unit is located in the slitting execution component and is used to detect the temperature of the gas flowing through the slitting execution component to generate a detected temperature value. The pressure detection unit is located in the hollow roller body and is used to detect the internal pressure of the hollow roller body to generate a detected pressure value. The controller is configured with a balanced control strategy, which generates control commands based on the detected temperature and pressure values ​​to control the operation of the air source. Through temperature and pressure detection, accurate control of the cutter during the slitting process is ensured, and the output of corresponding cooling capacity and airflow is dynamically configured according to the slitting conditions and the heat generated by the cutter.

[0013] Furthermore, the gas source includes a cold energy generator, which is used to cool the gas. The equalization control strategy includes a temperature control sub-strategy, which generates a temperature control sub-command based on the detected temperature value to control the operation of the cold energy generator. Through the design of the cold energy generator, the cooling gas is used to quickly achieve cooling of the cross-section, preventing the adhesive from melting and causing unevenness on the cross-section.

[0014] Furthermore, the air source includes a blower for compressing gas, and the equalization control strategy includes a pressure control sub-strategy for generating a pressure control sub-command based on the detected pressure value to control the operation of the blower. By compressing the gas and feeding it into the cutting roller, the gas can provide auxiliary separating force, forming a corresponding air curtain to assist in cooling the cutting tool.

[0015] Furthermore, the slitting actuator includes an auxiliary heat dissipation component, which comprises a heat dissipation impeller and a drive gear set. The drive gear set meshes with the output gear of the drive actuator motor and drives the heat dissipation impeller to operate. The heat dissipation impeller faces the cutting blade. By providing the auxiliary heat dissipation component, cool gas can be quickly introduced into the blade surface to assist in heat dissipation, thereby reducing slitting waiting time and increasing blade life.

[0016] Furthermore, the auxiliary heat dissipation component also includes an exhaust shroud, which covers the cutting blade and has an exhaust pipe to discharge the gas inside. The exhaust shroud design prevents cold air from escaping and improves the cutting effect.

[0017] The main technical effects of this invention are reflected in the following aspects: the extrusion fit of the split cylinder is achieved by inserting the tubular tape, and the split cylinder corresponding to the split tape is separated from the whole at the moment of splitting by the elastic element in the split cylinder to form a split gap. At the same time, the air source introduces gas to dissipate heat from the tape split surface, preventing the tape split surface from melting due to excessive heat during the cutting process and causing the split surface to re-adhere. At the same time, rapid cooling of the split surface can improve the quality of the split cut surface. Attached Figure Description

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0027] Reference Figure 1 , 2 As shown, an auxiliary tape slitting machine includes a slitting actuator and a tape mounting mechanism;

[0028] The slitting execution mechanism includes a moving component and a slitting execution component. The slitting execution component is disposed on the moving component and moves under the drive of the moving component. The slitting execution component includes a drive execution motor 1121 and a plurality of execution cutters 1122. The drive execution motor 1121 is used to drive the execution cutters 1122 to work in order to slitting the tubular tape 200.

[0029] Reference Figure 1 As shown, the moving assembly includes a moving slide rail 1111 and a moving frame 1112. The moving frame 1112 moves on the moving slide rail 1111 to determine the corresponding cutting position. The moving frame 1112 moves directionally under the drive of a motor to ensure that the axial length of each section of tape is the same. The moving assembly may also include a pushing structure 1113, on which a cutting execution component is mounted. A servo motor drives a rack to advance and retract the cutting execution component. The pushing structure 1113 is used to advance the cutting blade 1122 and control the cutting stroke.

[0030] The slitting execution component includes a disc cutter. All disc cutters are driven to rotate synchronously by a drive motor 1121. The transmission between the drive motor 1121 and the disc cutters is achieved through a gear set to ensure that the rotational speed and torque of each disc cutter are the same. As shown in the figure, the number of disc cutters is set to five groups, which are driven by the same drive motor 1121. The working process is as follows: first, the lateral position is determined, and the moving frame 1112 is controlled to move to the corresponding position. The drive motor 1121 is controlled to work until the disc cutter reaches the predetermined speed. The disc cutter is pushed into the rotating tubular tape 200 by the push structure 1113, completing the cutting action and separating the tape at the end from the entire tubular tape 200. Then, the second part of the tubular tape 200 is slitted.

[0031] Reference Figure 2As shown, the tape mounting mechanism includes a rotating assembly, a roller clamping assembly, and several breaking rollers 123. The rotating assembly includes a rotating drive unit 1211, which drives the breaking rollers 123 to rotate. The roller clamping assembly clamps the breaking rollers 123. The roller clamping assembly, including a movable part 1221 and a fixed part 1222, is mounted on the base of the tape mounting mechanism. The movable part 1221 is equipped with a turntable 1223, which can expose the movable part 1221 under the drive of a reversing motor to insert the corresponding breaking roller 123. One end of the breaking roller 123 corresponding to the movable part 1221 is equipped with a quick bearing connector 1224, which is fixed to a pre-set bearing structure on the movable part 1221, so that the other end of the breaking roller 123... When the rotating part 1211 is driven to rotate, it can rotate flexibly while limiting the axial and radial vibration of the breaking roller 123 on the mechanism. The rotating component is set in the fixed part 1222. The fixed part 1222 includes a clamping mounting part set on the base. The fixed part 1222 has several clamping joints for cooperating with the joints on the other end of the breaking roller 123. When the clamping joints are engaged, the clamping joints and the breaking roller 123 can be circumferentially fixed. The other part of the clamping joints is engaged with the rotating part 1211 through a gear set or a pulley, so that when the rotating part 1211 is working, it drives each breaking roller 123 to rotate through the clamping joints. In this way, the cylindrical tape sleeved on the breaking roller 123 can be rotated and broken under the drive of the breaking roller 123. During operation, the fixing part 1222 is first moved outward to provide installation space, and then the breaking roller 123 is inserted. At this time, the breaking roller 123 is already fitted with a cylindrical tape. Then, the turntable 1223 drives it to rotate to the predetermined position, driving the fixing part 1222 to reset. The motor drives the fixing part 1222 to move inward, which clamps the corresponding breaking roller. The motor's thrust provides the clamping force required for clamping. It should be noted that the end of the breaking roller 123 that mates with the clamping joint is fitted with a sealing ring 1236, so that gas can be introduced into the breaking roller 123 through the clamping joint. The sealing ring 1236 achieves the clamping and fixing effect. When another set of breaking is needed, the fixing part 1222 is moved out, the turntable 1223 is rotated, and the other set of breaking rollers 123 is switched, realizing the switching breaking.

[0032] like Figure 4As shown, the slitting roller 123 includes a hollow roller body 1231 and a plurality of slitting sleeves 1232. Separating elastic elements 1233 are provided between the slitting sleeves 1232 to provide elastic force, thereby forming a slitting gap between the slitting sleeves 1232. When the tubular tape 200 is installed on the slitting roller 123, the separating elastic elements 1233 are compressed to cause the slitting sleeves 1232 to abut against each other. The length of the slitting sleeves 1232 matches the slitting length. A plurality of air venting grooves 1234 are provided on the hollow roller body 1231. The separating elastic elements 1233 include elastic protrusions evenly distributed circumferentially around the slitting sleeves 1232. A pin structure 1235 is provided between the slitting sleeves 1232 to restrict relative rotation between them. The separating elastic element 1233 achieves separation between the splitting sleeves 1232 through elastic force. Specifically, at least four separating elastic elements 1233 and four corresponding pin structures 1235 are circumferentially and equally distributed on the splitting surface of the splitting sleeve 1232. The pin structures 1235 keep the splitting sleeve 1232 as a whole. When the tubular tape is installed, the inner surface of the tubular tape and the splitting sleeve contact friction to compress the separating elastic elements 1233. The separating elastic elements 1233 resist each other and squeeze to accumulate elastic potential energy. When the tubular tape is cut, the elastic force of the separating elastic element 1233 is output, which drives the tubular tape to separate from the separating elastic element 1233, thus completing the splitting process and generating a splitting gap. At the same time, the design of the pin structure 1235 prevents the splitting sleeve 1232 from circumferentially misaligning.

[0033] Reference Figure 3 As shown, the tape mounting mechanism also includes an air inlet assembly, which is specifically configured as an air chamber. The air inlet assembly includes an air inlet end 1241 and several air outlet ends 1242. The air inlet end 1241 is used to connect to an air source 150, and each of the air outlet ends 1242 is connected to a hollow roller body 1231. Cooling gas can be input through the air source 150, allowing the separated surfaces to cool down promptly and preventing adhesion.

[0034] Reference Figure 5As shown, the controller 130 and sensing components include a temperature detection unit 141 and a pressure detection unit 142. The temperature detection unit 141 is disposed on the slitting execution component and is used to detect the temperature of the gas flowing through the slitting execution component to generate a detected temperature value. The pressure detection unit 142 is disposed on the hollow roller body 1231 and is used to detect the air pressure inside the hollow roller body 1231 to generate a detected air pressure value. The controller 130 is configured with a balanced control strategy, which is used to generate control commands based on the detected temperature value and the detected air pressure value to control the operation of the gas source 150. The gas source 150 includes a cooling generator 151, which is used to cool the gas. The balanced control strategy includes a temperature control sub-strategy, which is used to generate temperature control sub-commands based on the detected temperature value to control the operation of the cooling generator 151. The gas source 150 includes a blower 152, which is used to compress gas. The equalization control strategy includes a pressure control sub-strategy, which is used to generate a pressure control sub-command based on the detected pressure value to control the operation of the blower 152.

[0035] The controller 130 is equipped with a balanced control strategy. This strategy operates over the entire tape slitting cycle, with the dual control objectives of maintaining the thermal balance of the cutting blade 1122 and stabilizing the air pressure inside the hollow roller 1231. By synchronously acquiring and detecting temperature and air pressure values, the controller triggers and calculates the control logic, ultimately generating a coordinated control command for the air source 150 to control its operating state. This achieves dynamic adaptation between cooling output and air pressure output, ensuring that the operating temperature of the cutting blade 1122 remains within a preset safe range during the slitting process, while simultaneously maintaining the air pressure inside the hollow roller 1231 at a preset stable level. The temperature range is used to ensure the cooling effect of the tape cutting surface and the auxiliary forming effect of the cutting gap. The detected temperature value is the real-time temperature data of the gas flowing through the cutting execution component, which is continuously collected by the temperature detection unit 141 at a fixed sampling period. The sampling period can be preset and adjusted according to the running speed of the cutting operation to ensure the real-time and continuous acquisition of temperature data. The detected air pressure value is the real-time air pressure data inside the hollow roller 1231, which is continuously collected by the air pressure detection unit 142 at the same sampling period as the temperature detection unit 141. This ensures that the temperature data and air pressure data are completely synchronized in the time domain, providing input parameters with consistent time dimension for subsequent collaborative control calculations. The balanced control strategy package... The process includes three steps: First, parameter presetting, which involves configuring all control parameters before the slitting operation begins. These parameters include the safe operating temperature range of the cutter 1122, the rated stable air pressure range of the hollow roller 1231, the rated output power range of the cold energy generator 151, and the rated output air pressure range of the blower 152. Second, synchronous sampling, which involves synchronously collecting and detecting temperature and air pressure values ​​according to a preset sampling period after the slitting operation begins, and transmitting the collected real-time data to the processing unit inside the controller 130. Third, strategy triggering and calculation, where the controller 130 processes the synchronously collected temperature values... The temperature control sub-strategy and the pressure control sub-strategy are compared with the preset safe operating temperature range. At the same time, the synchronously collected detection pressure value is compared with the preset rated stable pressure range. Based on the comparison results, the temperature control sub-strategy and the pressure control sub-strategy are triggered to generate corresponding temperature control sub-instructions and pressure control sub-instructions. The fourth step is the instruction output and closed-loop verification step. The controller 130 synchronously outputs the generated temperature control sub-instruction and pressure control sub-instruction to the execution unit corresponding to the air source 150. At the same time, after the data acquisition is completed in the next sampling cycle, the execution effect of the control instruction is verified in a closed loop. Based on the verification result, the subsequent control parameters are dynamically corrected to form a complete closed-loop control link.

[0036] The balanced control strategy includes a temperature control sub-strategy. This sub-strategy aims to stabilize the operating temperature of the cutting blade 1122. It performs calculations based on real-time collected temperature values ​​and generates temperature control sub-instructions to control the cooling power output of the cooling generator 151. The cooling generator 151 cools the gas entering the intake assembly, ensuring the output gas has adjustable cooling capacity. This achieves rapid cooling of the cutting blade 1122 and the tape cutting surface. The temperature control sub-strategy presets parameters before execution, including those related to the tape substrate and adhesive. The melting critical temperature of the layer, the upper limit of the rated operating temperature of the cutter 1122, the lower limit of the rated operating temperature of the cutter 1122, the minimum rated output power of the cold energy generator 151, and the maximum rated output power of the cold energy generator 151, together with the upper and lower limits of the rated operating temperature, constitute the safe operating temperature range of the cutter 1122. The temperature control sub-strategy adjusts the output power of the cold energy generator 151 by comparing the real-time collected detection temperature value with the safe operating temperature range. The corresponding calculation formula is as follows:

[0037] ,

[0038] This is the real-time output power of the cooling generator. This parameter is the final output of the temperature control sub-strategy and is directly used to generate temperature control sub-commands to adjust the operating state of the cooling generator. This is the base output power of the cooling capacity generator. This parameter is preset and configured based on the rated operating speed of the slitting operation before it starts. This is the proportional adjustment coefficient for the temperature control system. This parameter is preset and tuned based on the refrigeration response characteristics of the cooling capacity generator. This represents the detected temperature value collected during the current sampling period. To achieve the target operating temperature for the cutter, this parameter is set to the midpoint of the safe operating temperature range. This is the integral adjustment coefficient for the temperature control circuit. This parameter is preset and tuned based on the refrigeration response characteristics of the cooling capacity generator and the system inertia. This is the sequence number of the sampling period. This represents the total number of sampling periods accumulated at the current moment. For the first The detected temperature value collected in each sampling cycle. The target output power of the cooling generator is calculated using the above formula for a preset sampling period. A corresponding temperature control sub-instruction is then generated to reduce the output power of the cooling generator, avoiding energy waste and tape substrate shrinkage and deformation caused by excessive cooling output. At the same time, after each sampling period, the calculation result is compared with the rated output power range of the cooling generator to ensure that the final target output power is between the minimum and maximum rated output power, thereby ensuring the safe and stable operation of the cooling generator.

[0039] The balanced control strategy includes a pneumatic pressure control sub-strategy. This sub-strategy aims to stabilize the pneumatic pressure inside the hollow roller body. It calculates and generates pneumatic pressure control sub-commands based on real-time collected pressure values, thereby controlling the output pressure of the blower. The blower compresses the gas entering the intake assembly, ensuring adjustable output pressure. This guarantees stable gas output through the outlet slots of the hollow roller body, providing auxiliary separation force for the formation of the separating gap and simultaneously creating a stable air curtain to assist in the cutting action. The cooling and air pressure control sub-strategy presets parameters before execution, including the upper limit of the rated working air pressure of the hollow roller, the lower limit of the rated working air pressure of the hollow roller, the minimum rated output air pressure of the blower, and the maximum rated output air pressure of the blower. The upper and lower limits of the rated working air pressure together constitute the rated stable air pressure range of the hollow roller. The air pressure control sub-strategy compares the real-time collected detection air pressure values ​​with the rated stable air pressure range to perform adjustment calculations on the output air pressure of the blower. The corresponding calculation formula is as follows:

[0040] ,

[0041] The meaning of each parameter in the formula is explained one by one through complete statements. This parameter represents the real-time output air pressure of the blower. It is the final output of the air pressure control sub-strategy and is directly used to generate air pressure control sub-commands to adjust the operating state of the blower. This is the base output air pressure of the blower. This parameter is preset and configured before the slitting operation starts, based on the rated operating speed of the slitting operation and the specifications of the conveyor belt. This is the proportional adjustment coefficient for the air pressure control system. This parameter is preset and adjusted based on the air pressure response characteristics of the blower. This represents the detected air pressure value collected during the current sampling period. This is the target working air pressure for the hollow roller body; this parameter is set to the midpoint of the rated stable air pressure range. This is the differential adjustment coefficient for the air pressure control system. This parameter is preset and tuned based on the air cavity volume of the hollow roller and the air pressure response inertia of the system. This is the detection pressure value collected in the previous sampling cycle. For the preset sampling period, the execution steps of the air pressure control sub-strategy are as follows: First, the detected air pressure value collected in the current sampling period is compared with the rated stable air pressure range. When the detected air pressure value is within the rated stable air pressure range, the current output air pressure of the blower is kept unchanged. When the detected air pressure value is higher than the upper limit of the rated working air pressure, the target output air pressure of the blower is calculated using the above calculation formula, and a corresponding air pressure control sub-instruction is generated to reduce the output air pressure of the blower. When the detected air pressure value is lower than the lower limit of the rated working air pressure, the target output air pressure of the blower is calculated using the above calculation formula, and a corresponding air pressure control sub-instruction is generated to increase the output air pressure of the blower, ensuring that the gas can be stably output from the outlet channel, providing a stable auxiliary isolation force for the formation of the separation gap. At the same time, after the calculation is completed in each sampling period, the calculation result is compared with the rated output air pressure range of the blower to ensure that the final output target air pressure is between the minimum rated output air pressure and the maximum rated output air pressure, thereby ensuring the safe operation and stable operation of the blower.

[0042] Reference Figure 6 and Figure 7 As shown, the slitting actuator includes an auxiliary heat dissipation assembly, which includes a heat dissipation impeller 1131 and a drive gear set. The drive gear set meshes with the output gear of the drive actuator motor and drives the heat dissipation impeller 1131 to work. The heat dissipation impeller 1131 faces the actuator cutter 1122. The auxiliary heat dissipation assembly also includes an exhaust hood 1133, which covers the actuator cutter 1122. The exhaust hood 1133 is provided with an exhaust pipe 1134 to discharge the gas inside the exhaust hood 1133. By having the heat dissipation impeller 1131 work under the drive of the cutter, cool air is delivered to the actuator cutter 1122 to assist in cooling the actuator cutter 1122. The exhaust hood 1133 and exhaust pipe 1134 ensure sufficient contact between the cool air and the actuator cutter 1122, improving reliability.
