Description

Technical Field

[0001] This utility model relates to the technical field of tape slitting equipment, and more specifically, to a silicone oil control nozzle mechanism with scale adjustment for tape slitting equipment. Background Technology

[0002] In the tape production process, the slitting process is a crucial step that determines the dimensional accuracy and appearance quality of the finished tape. With the increasing demand for refined tape products in packaging, electronics, and building materials industries, the market places higher demands on the operational stability, cutting accuracy, and finished product consistency of tape slitting equipment. Among these, silicone oil coating control, as a core auxiliary process in tape slitting, directly affects the lubrication performance, anti-sticking effect, and subsequent winding quality of the tape substrate. Insufficient silicone oil coating can easily lead to the substrate sticking together after slitting and the spandex lifting, causing winding misalignment, finished product damage, or appearance problems. Excessive silicone oil coating, on the other hand, will result in material waste, and excess silicone oil may penetrate into the tape's adhesive layer, weakening the product's tack and affecting its performance. Currently, the silicone oil control nozzle mechanisms commonly used in tape slitting equipment mostly employ simple valve-type adjustment structures, such as manual shut-off valves, ball valves, or ordinary needle valves. These traditional mechanisms have the following significant drawbacks: First, low flow rate adjustment accuracy, relying on operator experience for manual adjustment with a lack of intuitive quantitative reference standards. This leads to significant fluctuations in silicone oil spraying volume among different operators and production batches, making it difficult to ensure consistent finished tape quality, especially in small-size, high-precision tape production scenarios. Second, poor adjustment stability. The valve core and channel in traditional mechanisms often have rigid contact or simple sealing structures. During long-term operation, vibration and media erosion can easily cause valve core position displacement, resulting in flow rate drift. Frequent shutdowns and recalibration are required, severely impacting production efficiency. Third, insufficient sealing performance and air pressure balance design. Some nozzle mechanisms are prone to silicone oil leakage during adjustment, polluting the production environment and increasing equipment maintenance costs. Furthermore, some mechanisms lack effective air pressure balance structures, leading to sudden internal air pressure changes during adjustment, causing instantaneous flow rate fluctuations and further reducing adjustment accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a silicone oil control nozzle mechanism with scale adjustment for tape slitting equipment, in order to solve the problems mentioned in the background art, such as low flow rate adjustment accuracy, reliance on operator experience for manual adjustment by turning, lack of intuitive quantitative reference standards, resulting in large fluctuations in silicone oil spraying amount among different operators and different batches of production, making it difficult to ensure the consistency of finished tape quality, especially in the production of small-size, high-precision tapes.

[0004] To achieve the above objectives, this utility model provides a silicone oil control nozzle mechanism with scale adjustment for tape slitting equipment, including a three-way pipe. One horizontal end of the three-way pipe has a liquid inlet, and the inner side of the liquid inlet is connected to a vertical liquid inlet channel. The other horizontal end of the three-way pipe has a liquid outlet. The vertical end of the three-way pipe has a liquid collecting end, the lower end of which communicates with the liquid inlet channel, and one lower side of which communicates with the liquid outlet. A fixing sleeve is threaded onto the outside of the liquid collecting end. A push rod is provided inside the fixing sleeve, and the lower end of the push rod has a tapered end. An adjusting sleeve is threaded onto the top of the fixing sleeve. The adjusting sleeve is pressed down by rotating the adjusting push rod, causing the tapered end to move up and down, thus cooperating with the liquid inlet channel to adjust the flow rate. A scale line is provided on the upper outer wall of the fixing sleeve to indicate the rotation scale of the adjusting sleeve.

[0005] This system uses a three-way piping system to form an "L-shaped + vertical" composite flow channel, with the inlet and outlet at the horizontal end and the collection end at the vertical end. Silicone oil introduced through the inlet first flows through the vertical inlet channel to the collection end, and then is guided to the outlet from the lower side opening of the collection end, achieving stable silicone oil delivery. The fixed sleeve is threadedly connected to the collection end, providing a mounting base for the push rod. The adjusting sleeve is threadedly fitted to the fixed sleeve; during tightening, the threaded drive causes the push rod to move axially, creating an adjustable annular gap between the tapered end of the push rod and the inlet channel. The smaller the gap, the greater the silicone oil flow resistance and the smaller the flow rate; conversely, the larger the gap, the greater the flow rate. The scale lines on the upper end of the fixed sleeve correspond to the tightening stroke of the adjusting sleeve. Each scale value matches a specific tapered end-inlet channel gap, transforming the "tightening action" into a "visual scale," providing a quantitative reference for flow rate adjustment.

[0006] Preferably, a limit nut is threadedly connected to the outer wall of the liquid collecting end at the lower end of the fixing sleeve.

[0007] This setup is based on the principle of "double threaded positioning and anti-loosening": the outer wall of the liquid collecting end is initially fixed to the fixed sleeve through a threaded connection, and after the limit nut is threaded with the outer wall of the liquid collecting end, its upper end face is tightly fitted with the lower end face of the fixed sleeve, forming an axial limit; when the fixed sleeve tends to loosen due to long-term vibration and media erosion, the limit nut can prevent the fixed sleeve from moving axially along the liquid collecting end, avoiding gaps in the threaded fit between the fixed sleeve and the liquid collecting end.

[0008] Preferably, the outer wall of the middle part of the fixing sleeve has a hexagonal structure, which facilitates the screwing and assembly of the fixing sleeve.

[0009] This feature is based on the principle of "tool compatibility optimization": the outer wall of the middle part of the fixed sleeve is designed with a hexagonal structure, which can precisely fit the clamping surface of a wrench (such as an open-end wrench or a box wrench). By utilizing the lever principle of the wrench, the operator can tighten the fixed sleeve with less effort, and quickly assemble or disassemble the fixed sleeve and the liquid collection end. Compared with a circular outer wall, the hexagonal structure avoids the problem of slippage when clamping tools and improves the efficiency of force transmission.

[0010] Preferably, a sealing ring is fitted in the middle of the top rod, and the sealing ring is located at the top opening of the liquid collecting end to seal the top of the liquid collecting end. A limiting boss is provided on the inner wall of the fixing sleeve near the upper part of the sealing ring to press and position the sealing ring.

[0011] The sealing ring in the middle of the push rod is made of an elastic material (such as nitrile rubber or fluororubber). Its outer diameter fits the inner wall of the fixing sleeve, and its inner diameter fits the outer wall of the push rod. At the same time, the lower end face of the sealing ring is in close contact with the edge of the top opening of the liquid collection end, forming a double seal of "radial + axial", which prevents silicone oil from leaking from the gap between the top opening of the liquid collection end and the push rod. The limiting boss on the inner wall of the fixing sleeve is located above the sealing ring, which can provide axial support for the sealing ring and prevent the sealing ring from being displaced upward when the push rod moves up and down. This ensures that the sealing ring is always in the sealing position of the top opening of the liquid collection end, avoiding seal failure.

[0012] Preferably, the top inner wall of the adjusting sleeve is provided with a spring, and the lower end of the spring abuts against the top of the push rod.

[0013] This setup is based on the principle of "elastic buffer + pressure compensation": the spring on the inner wall of the top of the adjusting sleeve is in a compressed state, and its lower end is always in contact with the top of the push rod, forming a continuous downward pressure; when the equipment vibrates or the silicone oil pressure fluctuates slightly, the push rod tends to move upward or downward. At this time, the spring compensates for the displacement of the push rod through its own elastic deformation (increase or decrease in compression), so that the fit clearance between the conical end and the liquid inlet channel remains stable; at the same time, the spring force can ensure that the position of the push rod is fixed after the adjusting sleeve is screwed on, avoiding the displacement of the push rod caused by the loosening of the adjusting sleeve.

[0014] Preferably, a pressure relief hole is provided on one side of the outer wall of the adjusting sleeve to balance the internal and external air pressure during screwing adjustment.

[0015] This setup is based on the principle of "pressure balance": the adjusting sleeve and the fixed sleeve are threaded together to form a closed space (located inside the adjusting sleeve, above the push rod). When the adjusting sleeve is turned, the push rod moves up and down, and the volume of the closed space changes accordingly (the volume increases when the push rod moves down and decreases when it moves up). If there is no pressure balance channel, the volume change will cause abnormal air pressure (negative or positive pressure) in the closed space, which will hinder the movement of the push rod or cause instantaneous fluctuations in flow. The pressure relief hole on the outer wall of the adjusting sleeve connects the closed space with the outside atmosphere, so that the air pressure in the closed space is always consistent with the outside, ensuring smooth movement of the push rod.

[0016] Preferably, the lower diameter of the conical end is smaller than the inner diameter of the liquid inlet channel, and the upper diameter of the conical end is larger than the inner diameter of the liquid inlet channel.

[0017] This setting is based on the principle of "linear flow regulation": the conical end adopts a conical structure with a smaller diameter at the bottom and a larger diameter at the top. The diameter at the bottom is smaller than the inner diameter of the inlet channel, ensuring that the conical end can be smoothly inserted into the inlet channel; the diameter at the top is larger than the inner diameter of the inlet channel, ensuring that the conical end will not completely detach from the inlet channel when it moves upward; when the push rod drives the conical end to move up and down, the annular gap area formed by the conical end and the inlet channel changes linearly with the displacement of the conical end (the amount of displacement is proportional to the amount of change in the gap area), thus making the silicone oil flow rate linearly related to the displacement of the conical end.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: In this tape slitting equipment, the silicone oil control nozzle mechanism with graduated adjustment transforms traditional experience-based "fuzzy adjustment" into visualized "quantitative adjustment" by setting graduated lines on the upper outer wall of the fixed sleeve and coordinating the linkage between the adjusting sleeve and the push rod. Operators can visually read the screwing position of the adjusting sleeve according to the graduated lines, precisely controlling the fit clearance between the lower conical end of the push rod and the inlet channel. When the adjusting sleeve is screwed down to press down the push rod, the conical end moves down, reducing the cross-sectional area of ​​the inlet channel and decreasing the silicone oil flow; conversely, it increases the flow. Combined with the structural design where the lower diameter of the conical end is smaller than the inner diameter of the inlet channel, and the upper diameter is larger than the inner diameter of the inlet channel, linear adjustment of the flow rate from "micro-flow" to "full flow" can be achieved. This quantitative adjustment method not only avoids adjustment deviations between different operators and different batches of production, but also quickly matches the optimal amount of silicone oil spraying for tape substrates of different specifications and materials. It effectively solves the problems of "adhesion and breakage" or "weakened adhesion" caused by flow fluctuations in traditional mechanisms, and significantly improves the pass rate of the anti-stick performance of finished tapes. On the one hand, the spring on the inner wall of the top of the adjusting sleeve abuts against the top of the push rod, forming an elastic buffer structure. When the equipment vibrates during long-term operation or when there are slight fluctuations in silicone oil pressure, the spring can compensate for the slight displacement of the push rod through its own elastic deformation, preventing the fit clearance between the conical end and the liquid inlet channel from drifting. Compared with the traditional rigid contact structure, this significantly improves flow stability, effectively reduces the number of shutdowns for calibration due to flow drift, and significantly improves production efficiency. On the other hand, the limiting nut on the outer wall of the liquid collecting end can provide double positioning for the fixed sleeve, preventing axial displacement of the fixed sleeve due to loose threads during long-term use. This further ensures the assembly stability of the overall structure and avoids adjustment failures caused by component misalignment. In terms of sealing performance, the sealing ring in the middle of the top rod and the limiting boss on the inner wall of the fixed sleeve form a "double sealing and positioning" structure: the sealing ring fits against the top opening of the liquid collection end, which can completely block the leakage of silicone oil from the top of the liquid collection end. Compared with the traditional simple sealing structure, it significantly reduces the leakage rate, avoids silicone oil waste, prevents silicone oil from contaminating the equipment and production environment, and reduces the workload of cleaning and maintenance. In terms of air pressure balance, the pressure relief hole on one side of the outer wall of the adjusting sleeve can balance the air pressure inside and outside the mechanism in real time during the screwing adjustment process, avoiding the "instantaneous flow impact" phenomenon caused by sudden air pressure changes in traditional mechanisms, making the flow adjustment process more stable, further ensuring the uniformity of silicone oil spraying, and also reducing the wear at the threaded joint between the adjusting sleeve and the fixed sleeve, significantly extending the service life of the components.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a silicone oil control nozzle mechanism with graduated adjustment for tape slitting equipment, such as... Figures 1-4 As shown, the system includes a three-way pipe 1. One horizontal end of the three-way pipe 1 is provided with an inlet 11, and the inner side of the inlet 11 is connected to a vertical inlet channel 13. The other horizontal end of the three-way pipe 1 is provided with an outlet 12. The vertical end of the three-way pipe 1 is provided with a collecting end 14. The lower end of the collecting end 14 is connected to the inlet channel 13, and one side of the lower part of the collecting end 14 is connected to the outlet 12. A fixing sleeve 2 is threadedly connected to the outside of the collecting end 14. A push rod 4 is provided inside the fixing sleeve 2. The lower end of the push rod 4 is provided with a tapered end 42. An adjusting sleeve 3 is threadedly connected to the top of the fixing sleeve 2. The adjusting sleeve 3 is pressed down by rotating the adjusting push rod 4, which drives the tapered end 42 to move up and down, thereby cooperating with the inlet channel 13 to adjust the flow rate of the channel. A scale line 21 is provided on the upper outer wall of the fixing sleeve 2 to indicate the rotation scale of the adjusting sleeve 3.

[0022] The scale line 21 enables visualization and standardization of flow regulation, avoiding adjustment deviations caused by operators relying on experience and ensuring consistent flow rates in different scenarios and by different operators. The combination of the conical end 42 and the liquid inlet channel 13 allows for continuous adjustment from "microflow" (very small gap) to "full flow" (largest gap), adapting to the silicone oil usage requirements of different tape substrates (such as thin PET and thick BOPP). The integrated flow channel design of the three-way pipe 1 reduces the leakage risk of traditional multi-pipe splicing, while the vertical structure of the liquid collection end 14 provides ample installation space for the top rod 4, ensuring precise matching between the adjustment components and the flow channel.

[0023] In this embodiment, the outer wall of the liquid collecting end 14 is threadedly connected to the lower end of the fixing sleeve 2 with a limit nut 22.

[0024] To prevent the position of the push rod 4 from shifting due to the loosening of the fixed sleeve 2, and to avoid abnormal changes in the fit clearance between the conical end 42 and the liquid inlet channel 13, thus ensuring the long-term stability of flow regulation; to reduce the regulation failure caused by the loosening of the fixed sleeve 2, eliminating the need for frequent shutdowns to retighten the fixed sleeve 2, and extending the fault-free operation time of the mechanism.

[0025] Specifically, the outer wall of the middle part of the fixing sleeve 2 has a hexagonal structure, which facilitates the screwing and assembly of the fixing sleeve 2.

[0026] The installation and disassembly time of the fixed sleeve 2 is shortened, especially in equipment maintenance and component replacement scenarios, reducing downtime. No special tools are required; operators can complete the operation with a regular wrench, reducing the special requirements for operating tools and improving the practicality of the mechanism.

[0027] Furthermore, a sealing ring 41 is fitted in the middle of the top rod 4. The sealing ring 41 is located at the top opening of the liquid collecting end 14 and is used to seal the top of the liquid collecting end 14. A limiting boss is provided on the inner wall of the fixing sleeve 2 near the upper part of the sealing ring 41 to press and position the sealing ring 41.

[0028] The sealing ring 41 in the middle of the push rod 4 is made of elastic material (such as nitrile rubber or fluororubber). Its outer diameter fits the inner wall of the fixing sleeve 2 and its inner diameter fits the outer wall of the push rod 4. At the same time, the lower end face of the sealing ring 41 is in close contact with the edge of the top opening of the liquid collection end 14, forming a double seal of "radial + axial", which prevents silicone oil from leaking from the gap between the top opening of the liquid collection end 14 and the push rod 4. The limiting boss set on the inner wall of the fixing sleeve 2 near the upper part of the sealing ring 41 can provide axial support for the sealing ring 41, preventing the sealing ring 41 from moving upward when the push rod 4 moves up and down, ensuring that the sealing ring 41 is always in the sealing position of the top opening of the liquid collection end 14, and avoiding sealing failure.

[0029] Furthermore, a spring 31 is provided on the top inner wall of the adjusting sleeve 3, and the lower end of the spring 31 abuts against the top of the push rod 4.

[0030] To counteract the effects of vibration and pressure fluctuations on the position of the push rod 4, prevent flow drift, ensure uniform silicone oil spraying, and improve the quality stability of the finished tape; to avoid displacement of the push rod 4 caused by slight loosening of the threads of the adjusting sleeve 3, to ensure that the adjusted flow parameters are effective for a long time, and to reduce repeated adjustment operations.

[0031] Furthermore, a pressure relief hole is provided on one side of the outer wall of the adjusting sleeve 3 to balance the internal and external air pressure during screwing adjustment.

[0032] Eliminating air pressure resistance makes it easier for operators to turn the adjusting sleeve 3, avoiding adjustment jamming caused by air pressure obstruction; preventing sudden air pressure changes in the enclosed space from impacting the position of the top rod 4, ensuring a smooth flow adjustment process, and avoiding tape spraying defects (such as excessive or insufficient silicone oil in some areas) caused by instantaneous flow abnormalities.

[0033] Furthermore, the lower diameter of the conical end 42 is smaller than the inner diameter of the liquid inlet channel 13, and the upper diameter of the conical end 42 is larger than the inner diameter of the liquid inlet channel 13.

[0034] The flow rate changes uniformly with the adjustment action. Operators can achieve precise flow rate control by finely adjusting the displacement of the push rod 4. It is especially suitable for the needs of small flow rate and high precision silicone oil spraying (such as narrow tape production). The linear adjustment characteristic prevents the flow rate from suddenly increasing or decreasing due to unreasonable design of the tapered end 42, ensuring a smooth silicone oil spraying process and reducing quality defects in the finished tape.

[0035] The specific steps for using the silicone oil-controlled nozzle mechanism with graduated adjustment in the tape slitting equipment of this utility model are as follows: 1. Assembly preparation stage First, fix the three-way pipe 1 at the designated position of the tape slitting equipment, ensuring that the liquid inlet 11 is connected to the silicone oil supply pipe and the liquid outlet 12 is connected to the nozzle pipe to ensure smooth flow. Then, insert the push rod 4 from the lower end of the fixed sleeve 2, so that the sealing ring 41 in the middle of the push rod 4 fits against the limiting boss on the inner wall of the fixed sleeve 2, ensuring that the sealing ring 41 is in a state of waiting to be sealed; Connect the fixed sleeve 2 with the assembled push rod 4 to the liquid collection end 14 of the three-way pipe 1 by thread. After screwing the fixed sleeve 2 (using the hexagonal structure in the middle to adapt to the wrench, saving effort and preventing slippage) to the target position, tighten the limiting nut 22 on the outer wall of the liquid collection end 14 at the lower end of the fixed sleeve 2. The position of the fixed sleeve 2 is locked by the supporting action of the limiting nut 22 to prevent its axial displacement. Finally, place the spring 31 into the top inner wall of the adjusting sleeve 3, and then connect the adjusting sleeve 3 to the top of the fixed sleeve 2 with threads so that the lower end of the spring 31 abuts against the top of the push rod 4, thus completing the overall assembly. 2. Flow regulation phase Initial adjustment: Determine the scale value corresponding to the target flow rate based on the substrate of the tape to be cut (e.g., a small amount of silicone oil is needed for thin PP non-woven self-adhesive bandages, and an appropriate amount of silicone oil is needed for thick BOPP) and specifications (e.g., a small flow rate is needed for narrow tapes, and a large flow rate is needed for wide tapes). Tightening adjustment: The operator tightens the adjusting sleeve 3. To reduce the flow rate, tighten the adjusting sleeve 3 clockwise. The adjusting sleeve 3 compresses the spring 31 downward through the threaded drive. The spring 31 transmits the pressure to the push rod 4, causing the push rod 4 and the conical end 42 to move downward, reducing the annular gap between the conical end 42 and the liquid inlet channel 13, until the edge of the adjusting sleeve 3 is aligned with the target scale line 21 on the fixing sleeve 2. To increase the flow rate, tighten the adjusting sleeve 3 counterclockwise. The spring 31 returns to its elastic state, and the push rod 4 and the conical end 42 move upward, widening the annular gap. Again, the scale line 21 is used as a reference for positioning. Pressure balance: During the adjustment process, the volume of the closed space formed by the adjusting sleeve 3 and the fixed sleeve 2 changes as the adjusting sleeve 3 moves. At this time, the pressure relief hole on one side of the adjusting sleeve 3 connects the closed space with the outside atmosphere, balances the internal and external air pressure, avoids the pressure resistance from causing adjustment jamming or sudden changes in the position of the push rod 4, and ensures a smooth adjustment process.

[0036] 3. Stable Operation Phase Silicone oil delivery: When the silicone oil supply system is turned on, silicone oil enters the three-way pipe 1 from the inlet 11, flows to the collection end 14 through the inlet channel 13, is buffered in the collection end 14, and is delivered to the nozzle through the annular gap between the conical end 42 and the inlet channel 13, and is evenly sprayed on the surface of the tape substrate. Fluctuation compensation: During equipment operation, if the push rod 4 tends to displace due to vibration or slight fluctuations in silicone oil pressure, the spring 31 inside the adjusting sleeve 3 compensates for the slight displacement of the push rod 4 through elastic deformation (compressed when the pressure increases and reset when the pressure decreases), ensuring that the gap between the conical end 42 and the liquid inlet channel 13 is stable and avoiding flow drift. Sealing guarantee: The sealing ring 41 in the middle of the push rod 4 always fits against the top opening of the liquid collection end 14 and the inner wall of the fixing sleeve 2, preventing silicone oil from leaking from the top of the liquid collection end 14. At the same time, the limiting boss on the inner wall of the fixing sleeve 2 prevents the sealing ring 41 from moving with the push rod 4, ensuring that the seal is continuously effective. Parameter adjustment: If the tape substrate or specification is changed, repeat the operation of the "flow adjustment stage" and quickly switch to the corresponding flow rate through the scale line 21 without recalibration, thus improving production flexibility.
