Description

Technical Field

[0001] This utility model relates to the field of plastic blister tray technology, specifically to a plastic suction cup unwinding and unwinding device. Background Technology

[0002] Blister trays, also known as plastic inner trays, are made by forming a plastic sheet into a specific groove using a blister forming process. Products are placed in the groove to protect and enhance their appearance. There are also transport-type trays. The most common use of trays is for convenience.

[0003] Plastic blister trays are made by unwinding plastic rolls and conveying them to the bottom of the blister mold for blister forming. However, when installing the plastic rolls on the unwinding frame, manual handling of the plastic rolls is required, which is labor-intensive and inefficient. Therefore, we propose a plastic suction cup unwinding and cutting device to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a plastic suction cup unwinding and unwinding device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plastic suction cup unwinding and unwinding device, comprising a pair of mounting seats and a mounting frame disposed between the upper ends of the mounting seats, wherein the mounting frame is provided with sliding grooves on both the left and right sides, and a movable seat is slidably disposed between the two sliding grooves on the left and right sides, and a drive component is provided on the mounting frame to drive the movable seat to move.

[0006] A hydraulic push rod is provided on the outside of the movable seat. A U-shaped frame is provided at the push rod of the hydraulic push rod. Rollers are rotatable on both the front and rear sides of the U-shaped frame. A rotating rod for placing the material roll is placed between the rollers. Limiting discs are provided on both the front and rear surfaces of the rotating rod.

[0007] Using the above technical solution, the roll material is rolled to the middle of the space between the U-shaped frames. The driving component drives the moving seat to move downward in the chute, simultaneously driving the U-shaped frames and rollers downward. When it reaches a certain height, the rotating rod is removed, and the U-shaped frames are moved and opened by the hydraulic push rod. At the same time, the U-shaped frames continue to move downward, so that the material roll is located between the U-shaped frames. The rotating rod passes through the material roll, and the U-shaped frames move and merge, so that the rotating rod is located in the middle between the two rollers. The rotating rod is then lifted. After the lifting is completed, the driving component drives the moving seat to move upward, so that the rollers lift the material roll on the rotating rod, making it easier to unwind the material roll on the rotating rod by rotating the rollers.

[0008] As a preferred embodiment of the present invention, the drive assembly includes a connecting frame disposed between the upper ends of the movable seats, and a support frame disposed on the upper end of one of the mounting frames. The support frame is provided with a second hydraulic push rod, and the push rod of the second hydraulic push rod is connected to the connecting frame.

[0009] Using the above technical solution, the hydraulic push rod 2 can drive the connecting frame and the moving seat to move synchronously.

[0010] As a preferred embodiment of this utility model, a telescopic rod is provided between the U-shaped frame and the mounting frame.

[0011] By adopting the above technical solution, the telescopic rod provides telescopic support for the U-shaped frame, ensuring the stability of the U-shaped frame's movement.

[0012] In a preferred embodiment of this invention, the roller is located between the two limiting discs, and the limiting discs are in contact with the surface of the roller.

[0013] Using the above technical solution, the limiting plate limits the movement and prevents the two ends of the rotating rod from disengaging from the rollers.

[0014] As a preferred embodiment of this utility model, the lower end of the mounting bracket is provided with a pair of limiting blocks, and the other ends of the two limiting blocks respectively contact the upper surfaces of the two rollers.

[0015] Using the above technical solution, the limiting block contacts the roller, and the rotating rod between the limiting rollers prevents the rotating rod from detaching during unwinding.

[0016] As a preferred embodiment of this utility model, the mounting base is provided with a plurality of mounting holes.

[0017] The above technical solution allows for easy installation of the mounting holes, which facilitate the bolts passing through the holes to fix the mounting base onto the mounting carrier.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] This plastic suction cup unwinding and unwinding equipment works by rolling the roll of material to the middle of the space between the U-shaped frames. A drive assembly then moves the moving seat downwards within a chute, simultaneously lowering the U-shaped frames and rollers. Once a certain height is reached, the rotating rod is removed, and a hydraulic push rod moves the U-shaped frames to open. The U-shaped frames continue to move downwards, positioning the material roll between the U-shaped frames. The rotating rod passes through the material roll, and the U-shaped frames move and merge, positioning the rotating rod in the middle between the two rollers. This lifting mechanism then uses the drive assembly to move the moving seat upwards, allowing the rollers to lift the material roll on the rotating rod. This facilitates unwinding the material roll by rotating the rollers. Compared to existing technologies, this method avoids manual feeding, improving feeding efficiency and convenience.

[0024] 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.

[0025] Please see Figures 1 to 3 The plastic suction cup unwinding and unwinding equipment in this embodiment mainly consists of components such as mounting base 1, mounting frame 2, moving base 4, drive assembly, hydraulic push rod 8, U-shaped frame 9, roller 10, rotating rod 12, and limiting plate 13.

[0026] There is one pair of mounting bases 1, each with mounting holes at its four corners. By passing bolts through these mounting holes, the mounting base 1 can be securely installed and fixed on the mounting carrier, such as the workshop floor or a dedicated equipment mounting platform, providing a stable support foundation for the entire equipment.

[0027] Mounting bracket 2 is fixed between the upper ends of two mounting bases 1. Mounting bracket 2 is symmetrically distributed front and back, and serves to connect and support other components. Sliding grooves 3 are provided on the left and right sides of mounting bracket 2 to provide a track for the sliding of the movable base 4.

[0028] There are two movable seats 4, which are slidably set between the left and right slide grooves 3 respectively. The movable seats 4 can move up and down in the slide grooves 3, and a hydraulic push rod 8 is fixed on its outer surface.

[0029] The mounting frame 2 is equipped with a drive assembly that moves the movable seat 4. The drive assembly includes a connecting frame 6, a support frame 5, and a hydraulic push rod 7. The connecting frame 6 is fixed between the upper surfaces of the two movable seats 4, serving to connect the two movable seats 4. The support frame 5 is fixed to the upper surface of the rear mounting frame 2. The hydraulic push rod 7 is installed on the upper surface of the support frame 5, and the push rod of the hydraulic push rod 7 is connected and fixed to the connecting frame 6. By extending and retracting the hydraulic push rod 7, the connecting frame 6 and the movable seat 4 can be pushed to move up and down synchronously in the slide groove 3.

[0030] The hydraulic push rod 8 is fixed on the outer surface of the movable seat 4, and a U-shaped frame 9 is connected and fixed at its push rod. The hydraulic push rod 8 can drive the U-shaped frame 9 to move horizontally, so as to open and close the U-shaped frame 9.

[0031] The U-shaped frame 9 has rollers 10 rotatably mounted on both its front and rear sides. A telescopic rod 11 is fixed between the U-shaped frame 9 and the mounting frame 2. The telescopic rod 11 provides telescopic support for the U-shaped frame 9, ensuring the stability of the U-shaped frame 9 during movement.

[0032] The rollers 10 are rotatably mounted on the front and rear sides of the U-shaped frame 9. The rotating rod 12 is placed between the two rollers 10. The rollers 10 are located between the two limiting plates 13, and the limiting plates 13 are in contact with the surface of the rollers 10, which can prevent the two ends of the rotating rod 12 from leaving the rollers 10.

[0033] The rotating rod 12 is placed between two rollers 10 for placing the material roll. Limiting discs 13 are fixed on the front and rear surfaces of the rotating rod 12 to limit the material roll.

[0034] A pair of limiting blocks 14 are fixed to the lower surface of the mounting frame 2. The other ends of the two limiting blocks 14 contact the upper surfaces of the two rollers 10 respectively, which can limit the rotation rod 12 between the rollers 10 and prevent the rotation rod 12 from disengaging during unwinding.

[0035] Hydraulic push rod 1 (8) and hydraulic push rod 2 (7): Their outer shells are usually made of aluminum alloy, which is lightweight and high-strength, reducing the overall weight of the equipment and facilitating its installation and movement. The internal pistons, cylinders and other components are made of high-precision metal materials, such as alloy steel, to ensure the sealing and reliability of the hydraulic push rod and to accurately realize the telescopic action.

[0036] The roller 10 is made of wear-resistant rubber material. Rubber has good elasticity and wear resistance, which can reduce friction between the roller and the rotating rod 12, reduce noise during equipment operation, and extend the service life of the roller 10.

[0037] The telescopic pole 11 generally adopts a telescopic sleeve structure made of stainless steel, which has good telescopic performance and stability, and can provide reliable support for the U-shaped frame 9.

[0038] This equipment can be equipped with a control system to achieve automated control of hydraulic push rod 8 and hydraulic push rod 7. The control system mainly consists of a controller and an operation panel.

[0039] Controller: The controller adopts a programmable logic controller (PLC), which features flexible programming and high reliability. It can write corresponding control programs according to the equipment's workflow and requirements to achieve precise control of hydraulic push rod 8 and hydraulic push rod 7.

[0040] The control panel is located next to the equipment for easy operation. The control panel has buttons for start, stop, raise, and lower. Operators can send control commands to the controller by pressing the corresponding buttons to control the operation of the equipment.

[0041] Detailed structural design principles and usage steps,

[0042] Equipment installation: First, install and fix the mounting base 1 onto the mounting carrier by passing bolts through the mounting holes on the mounting base 1. Then, install the mounting frame 2, the movable base 4, the drive assembly, the hydraulic push rod 8, the U-shaped frame 9, the roller 10 and other components in sequence, ensuring that each component is installed firmly and connected reliably.

[0043] Initial state: When the equipment is in the initial state, hydraulic push rod 7 is in the retracted state, and the moving seat 4 is located at the upper end of the slide 3; hydraulic push rod 8 is in the retracted state, U-shaped frame 9 is in the combined state, and the distance between the two rollers 10 is small.

[0044] Place the material roll: Roll the material roll to the middle position below the U-shaped frame 9. At this time, the material roll is directly below the two rollers 10.

[0045] Lowering the U-shaped frame 9: Activate hydraulic push rod 7 to extend it, pushing the connecting frame 6 and the movable seat 4 downward within the slide groove 3. Simultaneously, this drives the U-shaped frame 9 and the rollers 10 downward. When the downward movement reaches a certain height, the action of hydraulic push rod 7 stops.

[0046] Remove the rotating rod 12: The operator removes the rotating rod 12 that is placed on the roller 10.

[0047] Opening the U-shaped frame 9: Activate the hydraulic push rod 8 to move the U-shaped frame 9 to both sides and open it. At the same time, continue to move the U-shaped frame 9 downward so that the material roll is located between the U-shaped frames 9.

[0048] Install rotating rod 12: Pass rotating rod 12 through the material drum, then start hydraulic push rod 8 to drive U-shaped frame 9 to move and merge in the middle, so that rotating rod 12 is located in the middle between two rollers 10, and rotating rod 12 is lifted.

[0049] Lifting the material roll: Re-start the hydraulic push rod 7 to move the moving seat 4 upward, so that the roller 10 lifts the material roll on the rotating rod 12. During the lifting process, the limiting plate 13 and the limiting block 14 play a limiting role to prevent the rotating rod 12 from separating from the material roll.

[0050] Unwinding operation: When the material roll is raised to the appropriate position, the rotating rod 12 is rotated synchronously with the rotating roller 10 through the contact and cooperation between the roller 10 and the rotating rod 12.

[0051] In summary, this plastic suction cup unwinding and unwinding equipment, through reasonable structural design and automated control, realizes automatic feeding and unwinding of material rolls, avoiding manual feeding, improving feeding efficiency and convenience, and has high practical value and promotion significance.

[0052] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0053] 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.
