Description

Technical Field

[0001] This utility model relates to the field of paper tube processing equipment technology, and in particular to an automated paper tube processing equipment that integrates cutting and double-end synchronous chamfering functions. Background Technology

[0002] Paper tubes, as core materials, are widely used in industries such as papermaking, film production, and chemical fibers. Their production process typically involves two core steps: first, a tube cutter cuts the long raw paper tubes into shorter tubes of specific lengths; then, these shorter tubes are transferred to a chamfering machine to chamfer both ends to facilitate subsequent use and prevent burrs. Currently, the commonly used production method is to use the tube cutter and chamfering machine as two separate pieces of equipment. This split-processing model has inherent drawbacks: the transfer of workpieces between the two machines relies on manual handling, resulting in unnecessary waiting time and logistics costs, leading to a lengthy production cycle and limited capacity; typically, two operators are needed to handle the tube cutting and chamfering machines respectively, and the back-and-forth handling between the two machines increases labor intensity; paper tubes are prone to bumps and damage during handling, and more seriously, secondary manual positioning on the chamfering machine makes it difficult to ensure the concentricity of the chamfered surface with the paper tube axis, resulting in poor product consistency; the two independent machines and the material turnover area between them occupy a large amount of workshop space, which does not meet the layout requirements of modern lean production.

[0003] Therefore, the market urgently needs a paper tube processing equipment that can efficiently integrate cutting and chamfering processes and optimize the operation process to overcome the many shortcomings of existing technologies. Utility Model Content

[0004] The present invention provides a paper tube processing equipment that can solve the above-mentioned problems.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A paper tube processing device, characterized in that it comprises:

[0007] frame;

[0008] The paper tube cutting mechanism is installed on the top of the frame. It includes a paper tube cutting spindle for clamping and rotating a long paper tube, and a cutter assembly for moving axially along the paper tube cutting spindle and radially cutting the long paper tube to obtain a paper tube of a preset length.

[0009] The chamfering mechanism is installed on the frame and located below the paper tube cutting mechanism. It includes two sets of chamfering components arranged opposite each other. The two sets of chamfering components are used to chamfer both ends of the cut paper tubes at the same time.

[0010] A chamfering feeding mechanism is used to convey the slit paper tubes to be processed to the processing position of the chamfering mechanism;

[0011] The device includes two sets of chamfering components mounted on movable chamfering seats. The device also includes a feed servo control mechanism for driving the two sets of chamfering seats to move synchronously toward each other to clamp and chamfer paper tubes of different lengths, or to move synchronously toward each other to release the chamfered paper tubes.

[0012] Furthermore, the cutter assembly includes: a cutter seat that can slide axially along the main shaft of the paper cutting tube on the frame, a cutter ball screw for driving the cutter seat to move axially, and a blade mounted on the cutter seat for performing radial cutting action.

[0013] Furthermore, the blade is mounted on the cutter moving slider, the cutter seat is fixed with a cutter slide rail perpendicular to the axis of the paper cutting tube main shaft, the cutter moving slider is slidably assembled on the cutter slide rail, and is driven to reciprocate by the cutter push cylinder.

[0014] Furthermore, each set of the chamfering assembly includes: a chamfering machine main motor for driving the paper tube mold to rotate, and a paper tube clamping device for clamping and fixing the paper tube to be processed during chamfering.

[0015] Furthermore, the paper tube clamping device includes: an upper paper tube clamp fixed to the chamfered seat, and a lower paper tube clamp that can move up and down relative to the upper paper tube clamp; the lower paper tube clamp is driven by a lower paper tube clamp cylinder.

[0016] Furthermore, the feed servo control mechanism includes: a dual-axis servo motor, and two chamfering ball screws respectively connected to the two output shafts of the dual-axis servo motor; the two chamfering ball screws are respectively threaded with the corresponding chamfering seats to drive the chamfering seats to move synchronously.

[0018] Furthermore, the paper cutting tube mechanism also includes a main shaft push rod, which is driven by a lifting cylinder to selectively support or release the free end of the paper cutting tube main shaft.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) This utility model integrates the two major processes of cutting and chamfering into one machine. After the operator completes the cutting, there is no need to carry the paper tube over a long distance. The operator only needs to take the cut paper tube from the cutting station above and place it on the chamfering feeding mechanism below. This greatly shortens the workpiece flow path, optimizes the operation process, and improves the overall production efficiency.

[0021] (2) Since all operations are completed on one machine, one operator can simultaneously handle cutting and feeding as well as chamfering and feeding. Compared to operating two separate machines, this effectively reduces personnel requirements and lowers labor costs.

[0022] (3) Although manual transfer is required, once the paper tube is placed into the chamfering feeding mechanism, the subsequent feeding, clamping and double-end synchronous chamfering process is fully automatic. In particular, its chamfering mechanism uses two sets of servo-driven chamfering components to process synchronously in opposite directions, which fundamentally ensures that the chamfer is concentric and symmetrical with respect to the paper tube axis, as well as the accuracy and consistency of the finished product length.

[0023] (4) The integrated design combines the functions of the two original devices into one, significantly reducing the overall footprint of the equipment, saving valuable production space in the workshop, and facilitating the planning and layout of the production line.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0030] Reference Figure 1 and Figure 2 This embodiment provides a paper tube processing equipment, which mainly consists of a paper tube cutting mechanism, a chamfering mechanism and a chamfering feeding mechanism installed on the same frame 1, realizing the integration of cutting and chamfering processes.

[0031] I. Paper Cutting Tube Mechanism

[0032] The paper tube cutting mechanism is located in the upper area of ​​the equipment and is used to cut long raw paper tubes to a fixed length. This mechanism includes:

[0033] Paper cutting tube spindle 3: Horizontally positioned, used to insert into the inner hole of the long paper tube to be cut. During operation, the paper cutting tube spindle 3 is driven to rotate by a power source (not shown). To facilitate the fixing of paper tubes with different inner diameters, a differential retaining ring 2 can be fitted onto the paper cutting tube spindle 3, which securely fixes the paper tube to the spindle and rotates synchronously with it through friction or expansion force.

[0034] Main spindle push rod 6: To ensure the stability of the long paper tube during high-speed rotary cutting, a main spindle push rod 6 is provided at the free end (the end away from the drive end) of the paper tube cutting main spindle 3. The top of the push rod 6 is forked and can be driven up and down by a lifting cylinder (not shown). When installing or removing the paper tube, the push rod 6 moves down to disengage from the main spindle; during the cutting operation, the push rod 6 moves up to support or lock the end of the main spindle, forming a stable support and preventing vibration of the paper tube cutting main spindle 3.

[0035] Cutting assembly: This is the core component that performs the cutting action. It includes a cutting holder, which is slidably mounted on a linear guide rail 4 that is axially aligned with the main shaft 3. A cutting ball screw 5 is also axially aligned with the main shaft 3 of the paper tube, and its nut is fixedly connected to the cutting holder. By driving the cutting ball screw 5 to rotate via a servo motor, the movement of the cutting holder along the main shaft 3 of the paper tube can be precisely controlled, thereby achieving precise positioning of the cutting position.

[0036] A cutter slide rail 9 is mounted on the cutter holder, perpendicular to the axis of the main shaft 3. A cutter moving slider is slidably mounted on the cutter slide rail 9. A cutter bushing 7 is fixed to the slider, and the blade 8 is rotatably mounted on the cutter bushing 7. A cutter advance cylinder 10 is also mounted on the cutter holder, and its piston rod is connected to the cutter moving slider. When cutting is required, the cutter advance cylinder 10 is activated, pushing the slider and the blade 8 radially into the paper tube on the main shaft 3 along the cutter slide rail 9. When the blade 8 contacts the rotating paper tube, it also rotates, achieving rolling cutting and a smooth cut. After cutting is completed, the cylinder 10 reverses its action, causing the blade 8 to retract.

[0037] II. Chamfering Mechanism and Feed Servo Control Mechanism

[0038] The chamfering mechanism is located below the paper tube cutting mechanism and is used to chamfer both ends of the cut paper tubes. It consists of two sets of identical chamfering assemblies arranged opposite each other.

[0039] Each chamfering assembly is mounted on a movable chamfering seat. The chamfering seat is slidably mounted on a chamfering seat linear guide rail 21 fixed to the lower part of the frame 1, ensuring smooth and precise movement.

[0040] The feed servo control mechanism drives the synchronous movement of the two chamfering seats. At its core is a dual-axis servo motor 20, whose two output shafts are connected to a chamfering seat ball screw 19 via couplings. These two ball screws 19 rotate in opposite directions, or are controlled by the servo system to rotate in opposite directions, and each engages with a nut on its corresponding chamfering seat. Thus, when the servo motor 20 rotates, the two chamfering seats move synchronously towards each other (for clamping the paper tube) or away from each other (for releasing the paper tube) along the linear guide rail 21. Through precise control of the servo motor, it can accommodate paper tubes of any length to be processed.

[0041] The core of each chamfering assembly consists of the chamfering machine main motor 11 and the paper tube abrasive 12. The motor 11 is horizontally mounted on the chamfering seat, with its motor shaft facing the center of the equipment. A conical or bowl-shaped paper tube abrasive 12 (such as a grinding wheel or belt abrasive wheel) is mounted on the end of the shaft. The two chamfering machine main motors 11 are arranged facing each other.

[0042] To securely hold the paper tube during grinding, each chamfering assembly is equipped with a paper tube clamping device. This device includes an upper paper tube clamp 13 and a lower paper tube clamp 14. The upper paper tube clamp 13 remains static, i.e., fixed relative to its chamfering seat. The lower paper tube clamp 14 is mounted on the telescopic end of the lower paper tube clamp cylinder 15. The clamping surfaces (such as V-grooves or forks) of the upper and lower clamps are arranged opposite each other. When the paper tube to be processed is delivered into position, the two lower paper tube clamp cylinders 15 operate simultaneously, driving the lower paper tube clamp 14 to move upward, pressing the paper tube upward against the upper paper tube clamp 13, thereby achieving a clamping and locking of the paper tube.

[0043] III. Chamfered Feeding Mechanism

[0044] The paper tubes to be processed after being cut by the paper tube cutting mechanism are removed and temporarily stored on the paper tube storage rack 18. Next to the paper tube storage rack 18, a paper tube pushing cylinder 17 is provided, whose piston rod is connected to the paper tube pushing component 16 (such as a push plate or push rod). The paper tube pushing cylinder 17 can drive the paper tube pushing component 16 to push the paper tubes on the paper tube storage rack 18 laterally to the processing center position of the chamfering mechanism, that is, exactly in the fork of the paper tube lower clamp 14 of the two sets of chamfering components.

[0045] The overall workflow of the paper tube processing equipment described in this embodiment is as follows:

[0046] Feeding and Cutting: The operator places a long raw material paper tube onto the paper cutting tube spindle 3 located at the top of the equipment, and the spindle push rod 6 moves upward to hold the spindle in place. The system starts, and the paper cutting tube spindle 3 rotates. The cutter ball screw 5 drives the cutter seat to move to the preset cutting point. The cutter advance cylinder 10 pushes the blade 8 to cut into and separate the paper tube.

[0047] Manual transfer and placement: After the slitting is completed, the operator removes the slitting paper tubes from the paper tube cutting spindle 3 and then places them on the paper tube storage rack 18 of the chamfered feeding mechanism below the equipment.

[0048] Automatic feeding and positioning: When the sensor on the paper tube storage rack 18 detects the paper tube, the control system instructs the paper tube push cylinder 17 to actuate, driving the paper tube pusher 16 to push the paper tube to the center of the clamping device at the chamfering station. Subsequently, the dual-axis servo motor 20 starts, driving the two sets of chamfering components to move towards each other through the chamfering seat ball screw 19, achieving initial positioning of the paper tube.

[0049] Clamping and synchronous chamfering: The two paper tube lower clamping cylinders 15 are activated, driving the paper tube lower clamping piece 14 to move upward and firmly clamp the paper tube. Subsequently, the two chamfering machine main motors 11 are started, driving the paper tube mold 12 to rotate at high speed and simultaneously polishing both ends of the paper tube to be processed, completing the chamfering.

[0050] Release and discharge: After the chamfering is completed, the main motor 11 of the chamfering machine stops. The dual-axis servo motor 20 drives the two sets of chamfering components to move in opposite directions, while the paper tube lower clamp 14 descends to release the processed finished paper tube.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
