Description

Technical Field

[0001] This utility model belongs to the field of silicone production winding technology, specifically, it relates to a tension-adjustable silicone product slitting and winding device. Background Technology

[0002] In the field of silicone product manufacturing, the slitting and winding of silicone tape is a core link connecting production with subsequent processing and storage. Its operational efficiency and quality directly affect the smoothness of the entire production process and the quality of the final product.

[0003] However, current traditional silicone tape winding devices have significant technical shortcomings in practical applications. After the winding operation is completed and the silicone tape is cut, traditional devices generally face a chain reaction of problems caused by the instantaneous loss of tension. Because the device itself lacks a specially designed effective end positioning structure, the cut silicone tape loses the continuous traction constraint during the winding process. Under its own flexibility and slight external interference, it is extremely easy to detach from the guide rollers or adjusting rollers in the winding path. This detachment not only requires workers to spend a lot of time accurately re-threading the silicone tape between the rollers when restarting the winding operation, but also significantly extends equipment downtime due to the cumbersome operation process, severely reducing the continuous operation efficiency of the device.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] An electric push rod is installed on the base and is positioned at the center of the positioning roller and the take-up roller. A positioning frame is installed at the output end of the electric push rod. A slider is vertically slidably arranged on the side wall of the positioning frame, and a compression spring is installed between the slider and the positioning frame. An adjusting roller is rotatably installed on the slider. A crossbeam is installed on the top of the positioning frame, and a pressure plate is installed at the bottom of the crossbeam. The pressure plate is arc-shaped. A silicone strip is also installed on the base. The silicone strip is in sequence attached to the bottom of the positioning roller and the bottom of the adjusting roller, and the end of the silicone strip is connected to the winding roller.

[0007] In a preferred embodiment of the present invention, a support base is installed at the four corners of the base bottom. The support base is in the shape of a boss, and an anti-slip pad is installed at the bottom of the support base.

[0009] In a preferred embodiment of this utility model, a sliding plate is installed on the side wall of the positioning frame, and a sliding rod is movably installed through the sliding plate. The bottom of the sliding rod is installed on the base, and a limiting plate is installed on the top of the sliding rod. The diameter of the limiting plate is larger than the diameter of the sliding rod.

[0010] In a preferred embodiment of this utility model, a synchronous shaft is installed at the rotation center of the adjusting roller, the end of the synchronous shaft is slidably connected to the slider, a through groove is provided on the side wall of the positioning frame, and the slider is slidably disposed on the inner side wall of the through groove.

[0012] Compared with the prior art, the present invention has the following advantages: After the winding operation is completed and the silicone tape is cut, the tension disappears instantly. The compression spring can use its restoring elastic potential energy to push the slider to move the adjusting roller upward, and cooperate with the arc-shaped pressure plate at the bottom of the top beam of the positioning frame to clamp and position the end of the silicone tape. This design can effectively prevent the silicone tape from falling off the adjusting roller due to loss of restraint, thereby saving the tedious operation of re-threading the silicone tape and reducing the time required for repositioning.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 4 As shown, a tension-adjustable silicone product slitting and winding device includes a base 1 and a positioning roller 12 and a winding roller 13 rotatably mounted on the base 1.

[0018] An electric push rod 16 is installed on the base 1, and the electric push rod 16 is positioned at the center of the positioning roller 12 and the take-up roller 13. A positioning frame 143 is installed at the output end of the electric push rod 16. A slider 142 is vertically slidably arranged on the side wall of the positioning frame 143, and a compression spring 146 is installed between the slider 142 and the positioning frame 143. An adjusting roller 14 is rotatably installed on the slider 142. A crossbeam 148 is installed on the top of the positioning frame 143, and a pressure plate 149 is installed at the bottom of the crossbeam 148. The pressure plate 149 is arc-shaped. A silicone strip 15 is also installed on the base 1. The silicone strip 15 is in sequence attached to the bottom of the positioning roller 12 and the bottom of the adjusting roller 14, and the end of the silicone strip 15 is connected to the winding roller 13.

[0019] like Figures 1 to 4 As shown in the specific embodiment, support seats 11 are installed at the four corners of the base 1. The support seats 11 are in the shape of bosses, and anti-slip pads are installed on the bottom of the support seats 11. The boss-shaped support seats 11 can enhance the contact stability between the base 1 and the ground, and the bottom anti-slip pads can further increase the friction, preventing the device from sliding due to vibration or traction during the winding operation, and ensuring the structural stability of the entire device during operation.

[0020] like Figures 1 to 4As shown, a first connecting frame 121 is bolted to one side of the base 1, and a second connecting frame 132 is bolted to the other side of the base 1. The first connecting frame 121 is rotatably connected to the positioning roller 12, and the second connecting frame 132 is rotatably connected to the take-up roller 13. Baffles 131 are installed at both ends of the take-up roller 13. A bracket 134 is installed on the side wall of the base 1, and a drive motor 133 is mounted on the bracket 134. The drive motor 133 is connected to the rotation center of the take-up roller 13. The bolted connection of the first connecting frame 121 and the second connecting frame 132 facilitates the installation and disassembly of the positioning roller 12 and the take-up roller 13, and ensures the stability of their rotation. The baffles 131 at both ends of the take-up roller 13 prevent the silicone tape 15 from shifting and falling off during winding. The drive motor 133 fixed to the bracket 134 stably provides power to the take-up roller 13, ensuring a continuous and stable winding process.

[0021] like Figures 1 to 4 As shown, furthermore, a sliding plate 161 is installed on the side wall of the positioning frame 143, and a sliding rod 162 is movably installed through the sliding plate 161. The bottom of the sliding rod 162 is installed on the base 1, and a limiting plate 163 is installed on the top of the sliding rod 162. The diameter of the limiting plate 163 is larger than the diameter of the sliding rod 162. The cooperation between the sliding plate 161 and the sliding rod 162 can provide precise guidance for the lifting and lowering of the positioning frame 143, preventing the positioning frame 143 from shifting under the push of the electric push rod 16, and ensuring the accuracy of the pressure adjustment of the silicone belt 15 by the adjusting roller 14. The limiting plate 163 at the top of the sliding rod 162 can prevent the sliding plate 161 from detaching from the top of the sliding rod 162, further improving the reliability of the structure operation.

[0022] like Figures 1 to 4 As shown, a synchronous shaft 141 is further installed at the rotation center of the adjusting roller 14. The end of the synchronous shaft 141 is slidably connected to the slider 142. A through groove 144 is provided on the side wall of the positioning frame 143, and the slider 142 is slidably disposed on the inner side wall of the through groove 144. The synchronous shaft 141 ensures the synchronicity of the rotation of the adjusting roller 14, and the sliding of the slider 142 in the through groove 144 provides space for the up and down movement of the adjusting roller 14, so that the adjusting roller 14 can flexibly adjust its position according to the tension change of the silicone belt 15, providing structural support for tension balance adjustment.

[0023] like Figures 1 to 4As shown, a boss 147 is further installed at the bottom of the through groove 144. The boss 147 is used to position the slider 142 at its lowest position. A rod 145 is vertically installed on the through groove 144, and the rod 145 passes through the slider 142. A compression spring 146 is sleeved on the rod 145, and both ends of the compression spring 146 are respectively engaged with the side wall of the slider 142 and the end face of the through groove 144. The boss 147 can limit the lowest position of the slider 142, preventing the adjusting roller 14 from excessively moving downward due to excessive pressure and damaging the silicone strip 15. The rod 145 can limit the extension and retraction direction of the compression spring 146, preventing the compression spring 146 from deviating when deformed, ensuring that the elastic force of the compression spring 146 can stably act on the slider 142, and ensuring the stability of tension adjustment.

[0024] The operating principle of a tension-adjustable silicone product slitting and winding device is as follows: Before the device is started and enters normal winding operation, the tension of the silicone tape 15 needs to be adjusted. At this time, the drive motor 133 drives the winding roller 13 to rotate. The winding roller 13 generates a continuous traction force on the silicone tape 15, while the positioning roller 12 guides and initially limits the silicone tape 15, so that the silicone tape 15 can be stably transmitted between the positioning roller 12 and the winding roller 13. During tension adjustment, the electric push rod 16 will push the positioning frame 143 to rise and fall as a whole according to the preset tension requirements. The positioning frame 143 drives the adjusting roller 14 to move synchronously. The adjusting roller 14 is attached to the bottom of the silicone strip 15 and applies downward pressure to it. At the same time, the slider 142 can slide vertically along the insertion rod 145 in the through groove 144 of the positioning frame 143. The compression spring 146 generates elastic deformation under the compression of the slider 142. Its elastic force is balanced with the tension of the silicone strip 15, and finally the silicone strip 15 reaches the preset tension state. At this time, the tension force acts on the adjusting roller 14, causing the adjusting roller 14 to maintain a downward posture, ensuring that the silicone strip 15 maintains a stable tension during the winding process, ensuring the flatness and winding quality of the silicone strip 15 during the winding process. At the same time, the baffles 131 at both ends of the winding roller 13 can prevent the silicone strip 15 from deviating and falling off from both sides of the winding roller 13 during the winding process.

[0025] After the winding operation is completed, the silicone tape 15 needs to be cut. At the moment the silicone tape 15 is cut, the continuous tension force generated by the winding roller 13 will disappear instantly, and the downward pull force acting on the adjusting roller 14 will also be released. Since the compression spring 146 was in a compressed state during the previous tension adjustment, it has elastic potential energy for reset. After the tension force disappears, the compression spring 146 will quickly release the elastic potential energy, pushing the slider 142 to slide upward along the insertion rod 145 in the through groove 144. The slider 142 drives the synchronous shaft 141 and the adjusting roller 14 connected to the synchronous shaft 141 to move upward synchronously. During this process, the arc-shaped pressure plate 149 at the bottom of the top beam 148 of the positioning frame 143 plays a role. As the adjusting roller 14 moves upward, the distance between the adjusting roller 14 and the pressure plate 149 gradually decreases. Finally, the adjusting roller 14 and the pressure plate 149 cooperate with each other to clamp and position the cut end of the silicone tape 15 between them. This design effectively prevents the silicone tape 15 from falling off the adjusting roller 14 due to loss of restraint after the tension is lost, thus eliminating the tedious operation of re-threading the silicone tape 15. This not only improves the operating efficiency of the device but also reduces the repositioning time and material waste caused by the silicone tape 15 falling off. It ensures that when the winding operation is restarted, the silicone tape 15 can be quickly reconnected to the transmission path, ensuring the stability and convenience of continuous operation of the device.
