Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, and in particular to a winding and packaging device for waterproof membranes. Background Technology

[0002] After production, waterproof membranes need to be rolled up and packaged for transportation and storage. The quality of the rolling process directly affects the product's appearance, storage stability, and ease of subsequent construction.

[0003] A search revealed a prior art device for winding and packaging waterproof membrane and its working method (Announcement No.: CN120229589A), comprising a base and a side frame. The side frame is mounted on the base, and several conveying rollers for guiding and conveying the waterproof membrane are installed inside the side frame. A horizontal plate is installed inside the side frame, and a cutting groove is formed on the horizontal plate. A transverse cutter is slidably mounted in the cutting groove, and lifting pressure seats are provided on both sides of the transverse cutter. A rotating shaft is rotatably mounted inside the side frame, and a rotating plate is mounted on the rotating shaft. A winding roller is rotatably mounted inside the side frame, and a limiting groove is formed on the winding roller. A pusher ring is slidably mounted on the winding roller.

[0004] Existing devices mostly rely on the simple rotation of the take-up roller for winding, lacking a continuous compaction effect on the roll material. This easily leads to a loose interior and a tight exterior, resulting in "core collapse" or "chrysanthemum core" phenomena. This not only affects the appearance but also makes the roll material susceptible to edge damage due to loosening and collisions during transportation. It is also unable to adapt to dynamic changes in roll diameter. Although some devices are equipped with pressure rollers in fixed positions, the diameter of the roll material continuously increases during the winding process. The fixed pressure rollers either apply excessive pressure in the initial stage, damaging the core, or lose their compaction effect in the later stages due to the increased distance, resulting in uneven overall density of the roll material.

[0005] Therefore, we propose a winding and packaging device for waterproof membrane. Utility Model Content

[0006] The present invention mainly solves the technical problem of loose roll material winding and provides a winding and packaging device for waterproof roll material.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a winding and packaging device for waterproof membrane, comprising: A frame, wherein a plurality of guide rollers for guiding are rotatably connected to the frame, and a take-up roller for winding is also rotatably connected to the frame; The sorting structure, located at the bottom of the frame, is used to extrude the roll material. The sorting structure includes a frame, an extrusion roller, a threaded sleeve, a lead screw, and a servo motor. The extrusion roller is rotatably connected to the frame, the threaded sleeve is installed at the bottom of the frame, and the lead screw is threadedly connected to the threaded sleeve. The lead screw is driven by the servo motor, and the frame can push the extrusion roller close to the take-up roller to extrude the roll material.

[0008] In a preferred embodiment of this utility model, the frame is formed into a U-shape, and bearings are installed on both sides of the frame. The extrusion roller is rotatably connected to the frame through the bearings.

[0009] In a preferred embodiment of this invention, the threaded sleeve is fixedly installed at the center of the bottom of the frame via a flange, and a pressure sensor is provided between the flange and the frame.

[0010] In a preferred embodiment of this utility model, the servo motor is fixedly mounted on the bottom of the frame by a bracket, and the output shaft of the servo motor is locked and fixed to the lead screw by a flange.

[0011] In a preferred embodiment of this utility model, the organizing structure further includes telescopic rods, with two telescopic rods installed at the bottom of the frame for longitudinal guidance of the frame.

[0012] In a preferred embodiment of this utility model, the telescopic rod is fixedly installed at the bottom of the frame, the output shaft of the telescopic rod is fixedly connected to the bottom of the frame, and the two telescopic rods are symmetrically distributed.

[0013] In a preferred embodiment of this utility model, the finishing structure further includes a rubber coating and guide grooves. The rubber coating is fixedly installed with the extrusion roller. The rubber coating is in the shape of a cylindrical tube, and several guide grooves are formed radially on the outer circumference of the rubber coating. The guide grooves are spiral grooves.

[0014] This utility model provides a winding and packaging device for waterproof membrane rolls. It has the following beneficial effects: 1. This waterproof roll material winding and packaging device drives the extrusion rollers through a servo motor-screw mechanism and, with the feedback of a pressure sensor, can apply constant or varying pressure to the roll material according to a preset curve. No matter how much the roll diameter increases, the system can automatically adjust the position of the extrusion rollers to maintain a stable compaction effect, thereby ensuring uniform density from the core to the outside of the roll. This effectively avoids the phenomenon of loose inside and tight outside in traditional winding, resulting in a stiff roll material that is easy to transport and store.

[0015] 2. This innovative waterproof membrane winding and packaging device features spiral guide grooves on the rubber-coated surface of the extrusion roller. This design not only stretches the membrane surface to a certain extent but also utilizes the friction between the extrusion roller and the membrane surface during winding to automatically "wind" the packing tape into a designated position at the bottom of the membrane. This achieves simultaneous "compacting" and "tape threading," significantly shortening subsequent packaging operation time and laying the foundation for fully automated packaging lines. The radial pressure of the extrusion roller on the membrane helps suppress its lateral movement during winding, playing a certain role in correcting deviations and aligning the membrane. At the same time, the soft polyurethane coating provides sufficient friction without scratching the membrane surface, ensuring the product's appearance quality.

[0016] 3. This waterproof membrane winding and packaging device uses a closed-loop control system consisting of a servo motor and sensors to complete the entire compaction process. It features precise pressure control, fast response, and, compared with traditional power sources such as cylinders, screw drive has self-locking properties, high positional accuracy, and is safer and more reliable.

[0019] A winding and packaging device for waterproof membrane, such as Figure 1 As shown, it includes: The frame 10 is rotatably connected to a plurality of guide rollers 11 for guiding, and the frame 10 is also rotatably connected to a take-up roller 12 for winding. like Figure 2 , Figure 3 and Figure 4As shown, the sorting structure is set at the bottom of the frame 10 for extruding the roll material. The sorting structure includes a frame 20, an extrusion roller 21, a thread sleeve 23, a lead screw 24, and a servo motor 25. The extrusion roller 21 is rotatably connected to the frame 20. The thread sleeve 23 is installed at the bottom of the frame 20. The lead screw 24 is threadedly connected to the thread sleeve 23. The lead screw 24 is driven by the servo motor 25. The frame 20 can push the extrusion roller 21 close to the take-up roller 12 to extrude the roll material. The frame 20 forms a U-shaped frame. Bearings are installed on both sides of the frame 20. The extrusion roller 21 is rotatably connected to the frame 20 through the bearings. The thread sleeve 23 is fixedly installed at the center position of the bottom of the frame 20 through a flange. A pressure sensor is provided between the flange and the frame 20. The servo motor 25 is fixedly installed at the bottom of the frame 10 through a bracket. The output shaft of the servo motor 25 is locked and fixed to the lead screw 24 through the flange. In this scheme, a controller is connected to a servo motor 25 and a pressure sensor. When the servo motor 25 is powered on, the lead screw 24 rotates. The lead screw 24 moves the lead sleeve 23 upward, and the lead sleeve 23 drives the frame 20 to move vertically. The frame 20 pushes the extrusion roller 21 to abut against the roll material. On the one hand, it can limit the free end of the roll material, so that the take-up roller 12 can wind the end of the roll material to its surface. On the other hand, by dynamically adjusting the position of the frame 20, the extrusion roller 21 applies a constant pressure to the roll material, which can not only ensure the density of the roll material winding, but also adjust as the diameter of the roll material increases.

[0020] like Figure 3 and Figure 4 As shown, the sorting structure also includes telescopic rods 22. Two telescopic rods 22 are installed at the bottom of the frame 20 for longitudinal guidance of the frame 20. The telescopic rods 22 are fixedly installed at the bottom of the frame 10. The output shaft of the telescopic rods 22 is fixedly connected to the bottom of the frame 20. The two telescopic rods 22 are symmetrically distributed. The frame 20 is guided by the two telescopic rods 22, so that the frame 20 maintains stable and accurate longitudinal sliding.

[0021] like Figure 5 As shown, the finishing structure also includes a rubber coating 30 and guide grooves 31. The rubber coating 30 is fixedly installed with the extrusion roller 21. The rubber coating 30 is in the shape of a cylindrical tube. Several guide grooves 31 are opened radially on the outer circumference of the rubber coating 30. The guide grooves 31 are spiral grooves. The rubber coating 30 is made of polyurethane material. By setting the rubber coating 30 to abut against the roll material, it avoids scratching the roll material. The guide grooves 31 can be used to guide the packaging tape. The friction between the rubber coating 30 and the roll material, in conjunction with the spiral guide grooves 31, pushes the packaging tape to one side.

[0022] The working principle of this utility model: Initial stage and dynamic constant pressure compaction: The waterproof membrane is guided by the guide roller to the winding roller to begin winding.

[0023] The control system starts the servo motor, drives the lead screw to rotate, and then pushes the frame and the extrusion roller mounted on it to move upwards through the lead sleeve until the coating makes slight contact with the surface of the roll material.

[0024] The pressure sensor monitors the actual pressure value of the extrusion roller on the roll material in real time and feeds the signal back to the controller (such as PLC). The controller compares this pressure value with the preset target pressure value and dynamically adjusts the rotation of the servo motor through the PID algorithm (such as forward rotation to increase pressure and reverse rotation to decrease pressure) so that the actual pressure is always stable within the set range.

[0025] As winding progresses, the diameter of the roll material continuously increases, leading to increased pressure on the extrusion roller. Upon detecting this change, the pressure sensor immediately instructs the servo motor to reverse appropriately, causing the extrusion roller to retract slightly, thus maintaining a constant pressure. Throughout the process, the telescopic rod provides excellent guidance and stability, ensuring that the extrusion roller moves only vertically without any wobbling.

[0026] Strapping guide assistance: When winding is almost complete and packaging is required, the operator or auxiliary machinery can gently insert one end of the strapping into the spiral guide groove of the rotating extrusion roller. Due to the close contact and relative movement between the extrusion roller and the surface of the roll material under pressure, the strapping will be smoothly "carried" into the contact area between the roll material and the extrusion roller by the rotating extrusion roller, and guided along the trajectory of the spiral guide groove to one side of the roll material or wrapped several times. This is equivalent to completing the strapping threading work in advance. After winding is completed, the operator only needs to tighten and secure the strapping on the other side, greatly simplifying the packaging process.

[0027] Reset and next cycle: After winding and packaging are completed, the winding roller stops rotating, the controller controls the servo motor to reverse, and drives the extrusion roller to descend to the initial position, waiting for the start of the next roll.

[0028] The controller is a programmable logic controller with a pre-stored pressure control program. It receives analog signals from a pressure sensor (selectable model: S-type tension / compression sensor, range 0-2000N) located between the flange and frame 20. The controller compares the real-time pressure value with the set value (e.g., initially set to 100N, which can linearly increase to 300N as the roll diameter increases). It outputs speed commands to the servo drive through a PID control algorithm, thereby precisely controlling the forward and reverse rotation and speed of the servo motor, forming a complete pressure closed-loop control circuit.

[0029] The overlay 30 is cast from wear-resistant polyurethane material, with a Shore A hardness of 60-70 degrees recommended to balance elasticity and wear resistance. The overlay wall thickness is not less than 15mm. The guide groove is a single-headed or double-headed spiral groove with a spiral helix angle of 10-20 degrees, a groove depth of 3-5mm, and a groove width of 8-12mm. These parameters can effectively guide common PP strapping (10-15mm wide) and prevent it from jamming.

[0030] The servo motor 25 is preferably a low-inertia, high-response model, and its rated torque must be able to overcome the maximum load of the system (including the weight of the frame, the extrusion rollers, and the maximum working pressure). The lead screw should be a precision ball screw, and the lead can be selected according to the required lifting speed, such as 5mm or 10mm, to ensure the accuracy and stability of control.

[0031] The telescopic rod 22 can adopt a structure of self-lubricating linear bearing kit or oil-free bushing with optical axis to ensure that the frame moves flexibly in the vertical direction without radial sway.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
