Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a winding structure for plastic film after slitting. Background Technology

[0002] A film slitting machine is a device used to longitudinally cut wide film materials to a preset width. It is widely used in many industries such as packaging, printing, electronics, medical, and new energy. Through slitting, films can meet the size and specification requirements of different application scenarios, improving production efficiency and material utilization.

[0003] However, in traditional winding structures used for slitting plastic film, the film on the winding roller is quite heavy after the winding task is completed, making manual unloading extremely inconvenient and easily affecting production efficiency and personnel safety.

[0004] For example, in actual production, when the film is wound to a larger diameter, the weight of the winding roller may exceed the range that can be easily handled by manpower, resulting in a time-consuming and labor-intensive unloading process, which may even require multiple people to work together, seriously restricting the continuity and flexibility of the production line, and also posing operational risks. Utility Model Content

[0005] This utility model discloses a winding structure for plastic film after slitting, aiming to solve the technical problem that after the winding structure completes the winding task, the film on the winding roller is heavy, making manual unloading extremely inconvenient and easily affecting production efficiency and personnel safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winding structure for plastic film after slitting includes a slitting machine assembly and a winding roller. The slitting machine assembly has mounting grooves on opposite outer walls. The structure also includes:

[0008] Convenience Mechanism: The convenience mechanism is set on the outer walls of both sides of the slitting machine assembly. A cylinder is set on each outer wall of the slitting machine assembly, and a support rod is hinged to each outer wall of the slitting machine assembly. A telescopic rod is set on the piston end of the cylinder. One end of the telescopic rod is connected to one outer wall of the support rod. A placement groove is opened on one outer wall of the support rod. Two fixing sleeves are set on the outer circumference of the take-up roller through bearings. The fixing sleeves are set on the inner walls of the placement groove and the mounting groove. A transmission assembly is set on one end of the take-up roller.

[0009] Fixing mechanism: The fixing mechanism is installed on one side of the outer wall of the support rod.

[0010] In this case, the winding structure achieves automated unloading through a cleverly designed and convenient mechanism, improving production efficiency. After the winding roller completes its winding task, the cylinder drives the telescopic rod to extend, causing the support rod hinged to the outer wall of the slitting machine assembly to rotate around the hinge point. As the support rod rotates, the fixed sleeve set in the placement slot drives the winding roller to descend smoothly until it is close to the ground. The operator no longer needs to lift the heavy winding roller, reducing the risk of injury to the operator and providing a safer working environment. It also effectively prevents the winding roller from colliding with equipment or other objects, which could damage the equipment and affect its normal operation and service life.

[0011] In a preferred embodiment, the fixing mechanism includes a fixing rod with a protrusion on its top outer wall. A storage groove and a slot are respectively opened on the inner wall of the opposite side of the placement groove. A sliding groove is opened on the top inner wall of the storage groove. The fixing rod is slidably disposed on the inner wall of the storage groove, and one end of the fixing rod is connected to one side inner wall of the storage groove by a spring. A limit component is provided on one side outer wall of the support rod.

[0012] In particular, the sturdy fixing mechanism effectively prevents the take-up roller from accidentally falling off during the rotation of the support rod, ensuring the safety of the unloading process. When the take-up roller needs to be installed, simply push the protrusion to retract the fixing rod into the storage groove, and then place the take-up roller into the placement groove. The fixing rod will automatically pop out and return to its original position under the action of the spring, completing the fixing. When removing the take-up roller, simply press the fixing rod to retract it into the storage groove, and the take-up roller can be easily removed. The whole operation process is simple and quick, without complicated tools and operating steps, greatly saving time and labor costs.

[0013] As described above, a winding structure for plastic film after slitting includes a slitting machine assembly and a winding roller. The slitting machine assembly has mounting grooves on opposite outer walls. The structure also includes: a convenient mechanism: the convenient mechanism is located on both outer walls of the slitting machine assembly. Each outer wall of the slitting machine assembly has a cylinder, and each outer wall of the slitting machine assembly has a support rod hinged to it. The piston end of each cylinder has a telescopic rod, one end of which is connected to one outer wall of the support rod. One outer wall of the support rod has a placement groove. Two fixing sleeves are mounted on the circumferential outer wall of the winding roller via bearings. These fixing sleeves are located on the inner walls of the placement groove and the mounting groove. One end of the winding roller has a transmission assembly. A fixing mechanism: the fixing mechanism is located on one outer wall of the support rod. The winding structure for plastic film after slitting provided by this utility model has the technical effect of improving the ease of use and safety of the equipment. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The present invention discloses a winding structure for plastic film after slitting. It is mainly used in scenarios where the film on the winding roller is heavy after the winding structure has completed the winding task, and manual unloading is extremely inconvenient, which can easily affect production efficiency and personnel safety.

[0021] Reference Figure 1 , Figure 2 and Figure 3A winding structure for plastic film after slitting includes a slitting machine assembly 1 and a winding roller 2. The slitting machine assembly 1 has mounting grooves on opposite outer walls. The structure also includes: a convenient mechanism: the convenient mechanism is located on both outer walls of the slitting machine assembly 1. A cylinder 4 is located on both outer walls of the slitting machine assembly 1, and a support rod 5 is hinged to both outer walls of the slitting machine assembly 1. A telescopic rod is located at the piston end of the cylinder 4, and one end of the telescopic rod is connected to one outer wall of the support rod 5. A placement groove is located on one outer wall of the support rod 5. Two fixing sleeves 3 are located on the circumferential outer wall of the winding roller 2 via bearings. The fixing sleeves 3 are located on the inner walls of the placement groove and the mounting groove. A transmission assembly is located at one end of the winding roller 2. A fixing mechanism: the fixing mechanism is located on one outer wall of the support rod 5.

[0022] Both the placement groove and the installation groove have semi-circular longitudinal cross-sections at their bottoms, and their bottom radii of curvature are the same.

[0023] The combination of the two semi-circular groove bottoms can precisely clamp the fixing sleeve 3, which facilitates the installation of the take-up roller 2. This design improves the stability and convenience of the installation of the take-up roller 2.

[0024] In a specific implementation, this winding structure achieves automated unloading through a cleverly designed and convenient mechanism, improving production efficiency. After the winding roller 2 completes its winding task, the cylinder 4 drives the telescopic rod to extend, causing the support rod 5, which is hinged to the outer wall of the slitting machine assembly 1, to rotate around the hinge point. As the support rod 5 rotates, the fixed sleeve 3 set in the placement slot drives the winding roller 2 to descend smoothly until it is close to the ground. The operator no longer needs to lift the heavy winding roller 2, reducing the risk of injury to the operator and providing a safer working environment. It also effectively prevents the winding roller 2 from colliding with equipment or other objects, which could damage the equipment and affect its normal operation and service life.

[0025] Reference Figure 1 and Figure 2 In a preferred embodiment, the transmission assembly includes a first gear 6, which is disposed on the outer circumferential wall near one end of the take-up roller 2. A fixing frame 7 is disposed on one outer wall of the slitting machine assembly 1, and a motor is disposed on the top outer wall of the fixing frame 7. The output end of the motor is connected to a second gear 9, and the first gear 6 and the second gear 9 are used in cooperation.

[0026] Specifically, a transmission method in which the first gear 6 and the second gear 9 mesh with each other is adopted. The characteristic of gear transmission is that the transmission ratio is accurate, which can ensure that the power output of the motor is stably and accurately transmitted to the take-up roller 2. During the slitting and winding process of plastic film, the speed and torque requirements of the take-up roller 2 are relatively high. Precise power transmission can ensure that the take-up roller 2 winds at an appropriate speed and force, avoiding the situation of winding too tightly or too loosely, and ensuring the winding quality of plastic film.

[0027] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the fixing mechanism includes a fixing rod 10, a protrusion 11 is provided on the top outer wall of the fixing rod 10, a storage groove 12 and a slot are respectively provided on the inner wall of the opposite side of the placement groove, a sliding groove 13 is provided on the top inner wall of the storage groove 12, the fixing rod 10 is slidably disposed on the inner wall of the storage groove 12, and one end of the fixing rod 10 is connected to one side inner wall of the storage groove 12 by a spring, and a limit component is provided on one side outer wall of the support rod 5.

[0028] In particular, the stable fixing mechanism can effectively prevent the take-up roller 2 from accidentally falling off during the rotation of the support rod 5, ensuring the safety of the unloading process. When the take-up roller 2 needs to be installed, simply push the protrusion 11 to retract the fixing rod 10 into the storage groove 12, and then put the take-up roller 2 into the placement groove. The fixing rod 10 will automatically pop out and return to its original position under the action of the spring, thus completing the fixing. When disassembling the take-up roller 2, simply press the fixing rod 10 to retract it into the storage groove 12, and the take-up roller 2 can be easily taken out. The whole operation process is simple and quick, without complicated tools and operating steps, which greatly saves time and labor costs.

[0029] Reference Figure 3 In a preferred embodiment, the limiting component includes an extension plate 8, which is disposed on one outer wall of the support rod 5. Limiting strips 14 are provided on the bottom inner wall of the placement groove and the top outer wall of the extension plate 8, and a limiting groove is provided on the circumferential outer wall of the fixing sleeve 3.

[0030] The limiting component and the fixing mechanism work together to facilitate the installation of the take-up roller 2. When installing the take-up roller 2, the docking of the limiting strip 14 and the limiting groove can guide the fixing sleeve 3 to enter the placement groove at an accurate angle and cooperate with the fixing rod 10 of the fixing mechanism to make the fixation of the take-up roller 2 more secure. At the same time, it can make the first gear 6 on the take-up roller 2 mesh smoothly with the second gear 9.

[0031] Reference Figure 3 and Figure 4In a preferred embodiment, the height of the slot is the same as the thickness of the fixing rod 10, the width of the sliding groove 13 is greater than the circumferential diameter of the protrusion 11, and the depth of the limiting groove is adapted to the height of the limiting strip 14.

[0032] It should be noted that the design of the slot height being the same as the thickness of the fixing rod 10 allows the fixing rod 10 to be precisely inserted into the slot, achieving a seamless connection. This effectively prevents the fixing rod 10 from shaking or shifting within the slot, providing stable support for the take-up roller 2. The design of the sliding groove 13 being wider than the circumference diameter of the protrusion 11 provides sufficient space for the protrusion 11 to slide within the sliding groove 13 without obstruction. The design of the limiting groove depth matching the height of the limiting strip 14 allows the limiting strip 14 to be fully embedded in the limiting groove, providing precise positioning for the fixing sleeve 3.

[0033] Working principle: During use, the operator pushes the protrusion 11, and under the guidance of the sliding joint 13, retracts the fixing rod 10 into the receiving groove 12. At this time, the spring is compressed. Then, the fixing sleeve 3 on the take-up roller 2 is placed into the placement groove on the support rod 5, ensuring that the limiting strip 14 is precisely aligned with the limiting groove, guiding the fixing sleeve 3 into the placement groove at an accurate angle. Under the action of the cylinder 4, the support rod 5 drives the take-up roller 2 to rotate until the placement groove and the mounting groove combine to clamp the fixing sleeve 3, ensuring that the first gear 6 on the take-up roller 2 can smoothly mesh with the second gear 9. The protrusion 11 is released, and the fixing rod 10 is released under the elastic force of the spring. The lower part automatically pops out and returns to its original position, inserts into the slot, and completes the fixing of the take-up roller 2. The motor is started, and the output end of the motor drives the second gear 9 to rotate. The rotation of the second gear 9 will drive the first gear 6 to rotate, which in turn drives the take-up roller 2 to rotate, and begins the slitting and winding of the plastic film. When the take-up roller 2 completes the winding task, the cylinder 4 drives the telescopic rod to extend, which drives the support rod 5 to rotate around the hinge point. The fixed sleeve 3 set in the placement slot drives the take-up roller 2 to descend smoothly until it is close to the ground. At this time, the operator can easily take out the wound plastic film without having to lift the heavy take-up roller 2.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
