[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a cylindrical paper packaging machine with weighing function, comprising:

[0025] Table 1, drive mechanism 2, and wrapping mechanism 3. The drive mechanism 2 for rotating the cylindrical paper is installed inside the table 1, and the wrapping mechanism 3 for wrapping the packaging film around the surface of the cylindrical paper is provided on the top of the table 1.

[0026] The drive mechanism 2 includes a trough 21, a support frame 22, a contact roller 23, and a drive component 24. The trough 21 is opened in the table 1 for placing cylindrical paper. Two support frames 22 are provided in the trough 21. The contact roller 23 is rotatably installed in the support frame 22. The cylindrical paper is located on top of the two contact rollers 23. The drive component 24 is installed on the surface of one of the support frames 22 and is used to drive the contact roller 23 to rotate so as to realize the rotation of the cylindrical paper.

[0027] Specifically, a drive mechanism 2 and a surrounding packaging mechanism 3 are installed on the platform 1 to work together. The drive mechanism 2 slowly rotates the cylindrical paper, and the surrounding packaging mechanism 3 wraps the packaging paper on the packaging paper roll around the rotating cylindrical paper, achieving uniform packaging of the cylindrical paper. After packaging is completed, the hydraulic rod 61 is activated to drive the push plate 62 to move upward, lifting the packaged cylindrical paper. The weighing sensor 63 can detect the weight of the cylindrical paper. The drive mechanism 2 and the surrounding packaging mechanism 3 work together to realize the synchronous rotation of the cylindrical paper and the wrapping of the packaging film, reducing manual intervention and greatly improving packaging efficiency. The built-in weighing mechanism 6 can obtain the weight data of the cylindrical paper in real time after packaging is completed, avoiding secondary handling and weighing and reducing the complexity of operation.

[0028] A frame 4 is fixedly installed at the bottom of the table 1, and a base 5 is fixedly installed between the support frame 22 and the inner wall of the frame 4. A weighing mechanism 6 for weighing cylindrical paper is provided inside the frame 4.

[0029] Furthermore, a weighing mechanism 6 is set up to weigh the cylindrical paper.

[0030] The weighing mechanism 6 includes a hydraulic rod 61, a push plate 62 and a weighing sensor 63. The hydraulic rod 61 is fixed inside the frame 4, and the push plate 62 is installed on the top through the weighing sensor 63. The push plate 62 is located inside the trough 21 and is used to lift the cylindrical paper.

[0031] The hydraulic rod 61 uses a built-in hydraulic pump station and is equipped with an HSG series engineering hydraulic cylinder to ensure wear resistance and corrosion resistance. The load cell 63 is a YZC-516 model with ball joint bearings on the upper and lower surfaces for automatic self-alignment to eliminate the influence of lateral forces. O-rings are provided at the top and connection points of the sensor and the hydraulic rod 61 to prevent oil contamination. After packaging, the PLC sends a command to start the hydraulic pump station, the solenoid directional valve switches to the working position, and hydraulic oil enters the lower chamber of the hydraulic rod 61. The push plate 62 rises at a speed of 5mm / s. When the arc-shaped seat 7 contacts the bottom surface of the cylindrical paper and generates a pre-pressure of 0.5-1kN, the hydraulic system maintains the pressure. At this time, the load cell 63 collects data and transmits it to the PLC. After tare processing, the actual weight is displayed.

[0032] Arc-shaped seats 7 are fixedly installed on both sides of the top of the push plate 62, and guide rods 8 are fixedly installed on both sides of the bottom of the push plate 62. Sleeves 9 are slidably installed on the surface of the guide rods 8, and sleeves 9 are embedded in the frame 4.

[0033] It is worth noting that the arc-shaped seat 7 is made of polyurethane elastomer-coated steel frame with anti-slip texture on the surface. The elastic coating of the arc-shaped seat 7 can prevent scratching the surface of the cylindrical paper, and the anti-slip texture increases friction to avoid slipping during weighing. The precise fit between the guide rod 8 and the sleeve 9 ensures that the push plate 62 rises and falls accurately and that the weighing sensor 63 only bears the vertical load, thus improving the measurement accuracy.

[0034] The driving component 24 includes a driven wheel 241, a driving wheel 242 and a motor 243. The motor 243 is fixed in one of the support frames 22, and the driving wheel 242 is installed at the output end. The driven wheel 241 that meshes with the driving wheel 242 is fixedly installed at one end of the contact roller 23.

[0035] It should be noted that the motor 243 is a YE3-132M-4 type three-phase asynchronous motor, which is connected to the input shaft of the reducer through a flexible pin coupling. The output torque of the motor 243 is amplified by the reducer and transmitted to the contact roller 23 through the meshing of the drive wheel 242 and the driven wheel 241. The rubber layer on the surface of the contact roller 23 is made of styrene-butadiene rubber to ensure that the static friction coefficient between the roller and the cylindrical paper is >0.6, so as to achieve non-slip transmission and avoid tearing of the packaging film.

[0036] A protective cover 10 is fixedly installed on the inner wall of the tank 21, and the protective cover 10 is located on the surface of the driven wheel 241 and the driving wheel 242;

[0037] Among them, the protective cover 10 effectively prevents paper scraps and dust generated during the packaging process from entering the gear meshing area and reduces tooth surface wear.

[0038] The surrounding packaging mechanism 3 includes a rotating plate 31, a driver 32, a tray 33, and an insert rod 34. A top plate 11 is fixedly installed on the top of the table 1 by four columns. The rotating plate 31 is rotatably installed on the bottom of the top plate 11. The top of the tray 33 is fixedly installed on the surface of the rotating plate 31, and the surface is fixedly installed with an insert rod 34. The insert rod 34 is used for placing the packaging paper tubes. The top of the top plate 11 is provided with a driver 32 for rotating the rotating plate 31.

[0039] Furthermore, the driver 32 is powered by a servo motor 243, model SGM7G-75AFC61. Before packaging begins, the packaging paper tube is inserted into the insertion rod 34 and the clamping nut is tightened to secure it. The servo motor 243 is started, the rotating plate 31 rotates, and the contact roller 23 drives the cylindrical paper to rotate synchronously (linear speed matching). The packaging paper is drawn out from the paper tube and fixed at the starting end by the clamping device on the table 1. As the rotating plate 31 rotates, it achieves spiral winding. The winding angle can be controlled by adjusting the speed ratio between the rotating plate 31 and the contact roller 23. After packaging is completed, the packaging paper is cut with a knife.

[0040] A ring bracket 12 is fixedly installed at the bottom of the top plate 11, and support wheels 13 are installed on both sides of the bottom of the rotating plate 31. The ring bracket 12 is used to support the two support wheels 13.

[0041] Furthermore, the support wheel 13 assembly evenly transmits the weight of the rotating plate 31 and the working load to the annular bracket 12, reducing the load on the central bearing and extending the bearing life.

[0042] The weighing sensor 63, hydraulic rod 61, motor 243 and driver 32 involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.

[0043] This device lays the cylindrical paper rolls to be packaged flat in the trough 21, between two contact rollers 23. Each contact roller 23 has a fixed adhesive sleeve. A drive unit 24 for rotating the contact roller 23 is mounted on one of the support frames 22, allowing one contact roller 23 to rotate actively while the other rotates passively. The drive gear rotates upon activation, meshing with the driven gear to rotate the contact roller 23, which in turn causes the cylindrical paper rolls to rotate slowly. At this time, the driver 32 is activated, rotating the rotating plate 31. The bottom of the rotating plate 31 has a support plate 33, and a rod 34 for inserting the packaging paper roll is fixedly mounted on its surface. As the rotating plate 31 rotates, the packaging paper on the packaging paper roll is wound onto the slowly rotating cylindrical paper roll. A clamping component is provided at the top of the platform 1 to fix one end of the paper on the packaging paper roll, facilitating subsequent packaging. When the tube rotates, it can wrap the paper on the packaging paper tube around the cylindrical paper. After packaging is completed, the driver 32 and motor 243 stop, and the hydraulic rod 61 is started to drive the push plate 62 to move upward. The two arc-shaped seats 7 on the top of the push plate 62 lift the packaged cylindrical paper. Since a weighing sensor 63 is provided between the extension end of the hydraulic rod 61 and the push plate 62, the weight of the push plate 62 on the top of the weighing sensor 63 is included, similar to a peeling effect, so that the weighing sensor 63 only detects the weight of the cylindrical paper. The clamping component includes a base fixed to the top of the table 1. A clamping plate is installed in the base by a spring, and a pull rod is fixedly installed on one side of the clamping plate. The pull rod is slidably installed on the surface of the base. By pulling the pull rod, the clamping plate can be moved, the spring is squeezed, and one end of the paper on the packaging paper tube is placed between the clamping plate and the inner wall of the base. When the pull rod is released, the end of the paper on the packaging paper tube is clamped under the action of the spring.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
