Description

Technical Field

[0001] This utility model proposes a feeding structure for a tape machine, belonging to the field of tape production machinery and equipment. Background Technology

[0002] Tape feeding mechanisms are used for unwinding tape materials such as BOPP tape. Traditional manual feeding and handling of master rolls is labor-intensive and inefficient. Furthermore, the equipment or master roll is easily damaged due to collisions during the installation process. Existing mechanical feeding mechanisms only eliminate the operational risks of manual feeding, but they occupy a large area and require manual transport of the master roll to the mechanical feeding equipment when the tape is used up. Therefore, the utilization rate of space and time is not ideal. Currently, there is a need for a tape machine feeding structure with high time and space utilization. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model proposes a conveyor belt feeding structure to improve the insufficient time and space utilization of existing conveyor belt feeding structures in current operations. The technical features adopted are as follows:

[0004] A conveyor belt feeding structure includes a base, a hydraulic auxiliary feeding structure, an unwinding mechanism, and a noise muffler. The hydraulic auxiliary feeding structure includes a hydraulic cylinder fixed to the outside of the base. A roll support is provided on the side of the feeding port on the outside of the base. The outer side of the roll support is convex arc-shaped or folded. The movable rod of the hydraulic cylinder is connected to the tangent point on the outer side of the roll support. The bottom of the roll support is movably connected to the side of the base. The head of the roll support is provided with an arc groove for accommodating the unwinding shaft. When the mother roll is placed in the arc groove, the vertical distance from the arc groove to the base is greater than the radius of the mother roll to be fed, and it does not intersect with the opening and closing of the noise muffler.

[0005] Preferably, hydraulic cylinders and winding brackets are symmetrically installed on both sides of the base, and are connected to a synchronous control module.

[0006] Preferably, the unwinding mechanism assembly includes an unwinding shaft, an unwinding shaft support, a motor drive device, and an unwinding shaft positioning device.

[0007] Preferably, the tape machine feeding structure includes a soundproof cover that covers the unwinding mechanism assembly and the machine base, and the soundproof cover has a transparent observation window at the unwinding shaft.

[0008] Preferably, the tape machine feeding structure includes an unwinding pressure roller group, which includes a set of pressure roller frames synchronously and symmetrically installed on both sides of the machine base. The pressure roller frames are driven by cylinders that are synchronously and symmetrically fixed on both sides of the machine base, and a unwinding pressure roller is provided in the middle of the pressure roller frames.

[0009] Preferably, the feeding shaft is an air-expanding shaft.

[0010] Preferably, the tape machine feeding structure includes a foot pedal assembly, in which rollers are provided as channels for the tape material to pass through and for the layout design.

[0011] The beneficial effects of this utility model are as follows:

[0012] The hydraulic cylinder drives the roll holder to rotate, enabling mechanized lifting and transfer of the mother roll, significantly reducing manual labor intensity and improving feeding efficiency. The convex arc or folded design on the outer side of the roll holder, along with its movable connection, ensures a more rational movement trajectory of the mother roll during lifting, preventing collisions with components such as the machine base. The optimal setting of the maximum straight-line distance from the arc groove to the machine base ensures the mother roll can be smoothly placed on the roll holder and located outside the machine base, enabling advance material preparation and rapid feeding, improving work efficiency, laying the foundation for accurate subsequent installation into the unwinding mechanism, avoiding space limitations imposed by the roll holder, and improving space utilization.

[0013] The synchronous and symmetrical hydraulic cylinders and roll support on both sides ensure that the mother roll is subjected to balanced force during lifting and transfer, keeping the mother roll in a horizontal position at all times. This effectively avoids tilting and offset of the mother roll, improves the stability of feeding and the accuracy of mother roll installation, and reduces equipment failure and mother roll damage caused by uneven force.

[0014] The feeding shaft and its support work together to ensure smoother and more accurate placement of the feeding shaft on the support. Simultaneously, the motor drive precisely controls the feeding shaft's speed, ensuring stable tape unwinding speed and thus maintaining stable tape tension. The feeding shaft positioning device enables precise positioning of the feeding shaft, ensuring accurate placement of the tape master roll during unwinding, reducing tape deviation, and improving the quality of subsequent processing.

[0023] The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the embodiments.

[0024] In the description of this utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and "vertical" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Furthermore, in the description of this utility model, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0027] Unless otherwise specified, the materials, instruments and methods used in the following embodiments are all conventional materials, instruments and methods in the art and can be obtained through commercial channels.

[0028] Example 1

[0029] like Figure 1 , Figure 2 The conveyor belt feeding structure shown includes a base 1, a hydraulic auxiliary feeding structure 2, an unwinding mechanism group 3, and a noise muffler 4. The base 1, as the basic load-bearing component of the entire conveyor belt feeding structure, is welded from high-strength alloy steel and has sufficient structural strength to support the operation of each component.

[0030] In the hydraulic-assisted feeding structure 2, the hydraulic cylinder 21 is fixed to the outside of the machine base by bolt assembly. The connection surface between the cylinder body and the machine base is precision machined to ensure the verticality and stability of the installation. The roll support 22 on the side of the feeding port on the outside of the machine base is made of wear-resistant cast iron. Its outer side adopts a convex arc or folded structure design. The radius of curvature of the convex arc is larger than the outer diameter of the commonly used mother roll, while the folded shape adopts a two-section right-angle bend structure. This structural design has better mechanical strength than conventional straight rods and also prevents the mother roll from colliding with the machine base and other components during the lifting process. The end of the movable rod of the hydraulic cylinder 21 is connected to the tangential part of the outer side of the roll support through a hinge structure. This connection method allows the movable rod to flexibly adapt to angle changes when driving the roll support to rotate.

[0031] The bottom of the coil support 22 is movably connected to the side of the machine base via a hinge. The hinge shaft is made of high-strength alloy steel and chrome-plated to improve wear resistance and rust prevention. The inner wall of the arc groove 23 at the head of the coil support is inlaid with wear-resistant rubber pads. The diameter of the arc groove 23 is slightly larger than the diameter of the unwinding shaft. When the unwinding shaft with the mother coil is placed on the arc groove 23, the straight-line distance from the arc groove 23 to the machine base is greater than the radius of the mother coil to be loaded. When the coil support 22 is opened, a mother coil can be placed separately outside the machine base at a distance greater than the radius of the mother coil from the ground. This allows the coil support to prepare materials in advance when the feeder is working, achieving advance material preparation and rapid feeding. During feeding, the mother coil is driven by a hydraulic cylinder to transport the mother coil to the unwinding mechanism assembly.

[0032] In the hydraulic-assisted feeding structure 2, hydraulic cylinders 21 are installed on both sides of the machine base. The hydraulic cylinders 21 are identical in model and parameters, and their installation positions are symmetrical about the longitudinal centerline of the machine base. The roll support brackets 22 have the same structure and dimensions, and their installation positions on both sides of the machine base are also symmetrically distributed. A synchronous control module ensures that the speed and stroke of the hydraulic cylinders 21 on both sides are completely consistent during extension and retraction, thereby driving the roll support brackets 22 on both sides to move synchronously. The synchronous control module is a common control module, using a PLC control device combined with proportional valves, pressure sensors, and synchronous compensation oil circuits. The synchronous and symmetrical hydraulic cylinders and roll support brackets on both sides ensure that the mother roll is subjected to balanced force during lifting and transfer, guaranteeing that the mother roll remains horizontal, effectively preventing tilting and offset of the mother roll, improving the stability of feeding and the accuracy of mother roll installation, and reducing equipment failures and mother roll damage caused by uneven force.

[0033] In this embodiment, when the tape feeder is in operation, the hydraulic auxiliary feeding structure can be controlled in advance to open the roll holder and place the tape master roll in advance to complete the material preparation. When the master roll of the feeder is used up, the feeder can be changed by simple material change control. When running in multiple positions, the material transportation and material change time can be greatly reduced, and the time efficiency can be improved. In addition, the design that the roll holder does not intersect with the machine base and the soundproof cover makes the space utilization controllable and also improves the space utilization rate.

[0034] Example 2

[0035] like Figure 2 , Figure 3 The unwinding mechanism group 3 in the conveyor belt feeding structure shown includes an unwinding shaft 31, an unwinding shaft support 32, a motor drive device 33, and an unwinding shaft positioning device 34. The unwinding shaft 31 is an air-expanding shaft. Both ends of the unwinding shaft are mounted on the unwinding shaft support 32 through bearings. The unwinding shaft support 32 is a locking groove cast on the machine base 1, which is used to lock and fix with the bearings on the unwinding shaft.

[0036] The motor drive device includes a servo motor, a reducer, and a coupling. The servo motor is connected to the coupling through the reducer, and the other end of the coupling is connected to the feeding shaft 31, which can precisely control the speed and direction of rotation of the feeding shaft.

[0037] The feeding shaft positioning device 34 is used to directly limit the position of the feeding shaft. Adjustable metal blocks 35 are installed at both ends of the feeding shaft. The metal blocks 35 are controlled by telescopic cylinders. The metal blocks 35 are provided with arc grooves that fit with the bearings. When the feeding shaft is installed in place, the telescopic cylinder controls the metal blocks to fit with the bearings at the shaft ends. The positional accuracy of the blocks ensures consistent positioning. In addition, the machine base 1 is also provided with a positioning block 36 driven by a motor. The positioning block has pin holes that match the feeding shaft. When the feeding shaft is inserted, the pin holes on the positioning block and the shaft ends cooperate to achieve precise fitting and positioning, ensuring accurate positioning of the tape roll during unwinding, reducing tape deviation, and improving the quality of subsequent processing.

[0038] Example 3

[0039] like Figure 1 and Figure 4 The soundproof cover 4 in the conveyor belt feeding structure shown adopts a double-layer structure. The inner layer is lined with sound-absorbing cotton, and the outer layer is a steel plate. The two layers are connected by damping material, which can effectively absorb and block the noise generated during equipment operation. The soundproof cover 4 is connected to the machine base by a hinge, which is convenient to open and close. Its size completely covers the unwinding mechanism 3 and the machine base 1. When the rotation axis of the soundproof cover rotates to the farthest point in a straight line from the mother roll, it is offset. A transparent observation window 41 is installed on the soundproof cover 4 corresponding to the position of the unwinding shaft 31. It is made of high-strength acrylic sheet with a thickness of 5-8mm. The size of the observation window is suitable for clearly observing the running status of the unwinding shaft and the conveyor belt mother roll. The observation window and the soundproof cover are sealed with a sealing strip to ensure the soundproofing effect. The soundproof cover improves the working environment and protects the hearing health of operators. The transparent observation window allows operators to observe the running status of the unwinding shaft and the conveyor belt mother roll at any time, detect abnormalities in time and deal with them in time, and improve the safety and reliability of equipment operation.

[0040] The unwinding pressure roller group 5 in the conveyor belt feeding structure includes a set of pressure roller frames 51 synchronously and symmetrically installed on both sides of the machine base. A unwinding pressure roller 52 is located in the middle of the pressure roller frame, pressing against the conveyor belt master roll. The pressure roller frames 51 are die-cast from aluminum alloy, making them lightweight and high-strength. The pressure roller frames are driven by cylinders synchronously and symmetrically fixed on both sides of the machine frame. The cylinders are bolted to pre-set mounting plates on both sides of the machine frame. The piston rods of the cylinders are connected to the pressure roller frames 51 via pins, ensuring flexible rotation of the pressure roller frames. The air supply lines of the two sets of cylinders are connected to the same pneumatic control valve to achieve synchronization. The control system ensures that the pressure roller frames 51 on both sides move in unison, driving the unwinding pressure roller to ensure the stability and accuracy of unwinding. The pressure roller frame has a middle unwinding pressure roller 52, which can apply stable pressure to the master roll to prevent the master roll from loosening and shifting during unwinding. The unwinding pressure roller 52 is made of rubber, with a smooth surface and a certain degree of elasticity, which can avoid damage to the surface of the tape. The axle of the unwinding pressure roller 52 is mounted in the middle of the pressure roller frame 51 and can rotate freely through bearings. The free rotation of the pressure roller ensures that it will not affect the unwinding speed of the tape. The diameter of the pressure roller is determined according to the specifications of the tape master roll.

[0041] Example 4

[0042] like Figure 4 As shown, the conveyor belt feeding structure also includes a foot pedal assembly 6. The foot pedal assembly 6 comprises a pedal body and a fixed bracket. The pedal body is made of anti-slip steel plate with anti-slip textured surfaces. Rollers 61 are made of stainless steel and are mounted on the bracket below the pedal body via bearings. The spacing between the rollers is designed according to the width and layout requirements of the rubber material, forming a channel for the material to pass through, preventing tangling and wrinkling, ensuring the flatness and stability of the material during conveying, and facilitating smooth subsequent processing. The roller surfaces are polished, smooth and burr-free, preventing scratches on the rubber material. The roller positions can be finely adjusted according to actual production needs to adapt to different rubber material layouts, enhancing the flexibility and applicability of the equipment.

[0043] This utility model does not improve any software programs or methods. This utility model only designs the structure. The methods or software programs involved in the debugging and control of PLC control devices and sensors are all based on existing methods or software program design books, manuals or product manuals by those skilled in the art, combined with the functions involved in the principles and effects of this utility model, and can be implemented by writing their own programs.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
