Description

Technical Field

[0001] This utility model relates to the technical field of paper cup production equipment, and in particular to a guide rail-free single-rotation paper suction mechanism. Background Technology

[0002] A single-rotation paper suction machine is a type of equipment used in automated production lines, especially in the packaging or paper product manufacturing industry. Its main function is to use a rotating mechanism to pick up paper or paper cup molds and transfer them to the next production stage. This type of machine is commonly used in high-speed production lines, characterized by its high efficiency and stability. During operation, the suction cup system picks up products such as paper or paper cup molds. The suction cups use negative pressure to hold the items in place. Driven by a mechanical drive, the suction cups rotate, transferring the picked-up paper or paper cup mold to a designated position. The rotation can be unidirectional, hence the name "single rotation." After rotation, the items are accurately placed onto the next stage workstation or conveyor belt by the machine's structure, ensuring the smooth operation of the production process.

[0003] However, existing equipment often encounters the following problems during use:

[0004] Traditional rotary paper suction mechanisms typically rely on complex guide rail systems to guide the flipping trajectory of the suction cups, allowing the paper molds to be transported one by one. However, the guide rails wear down with repeated flipping, causing the guide grooves of the guide rails to expand, which in turn causes the flipping trajectory to deviate. Severe deviation can lead to the paralysis of paper mold transport. Utility Model Content

[0005] The main objective of this invention is to provide a guide rail-free single-rotation paper suction mechanism, effectively solving the problem mentioned in the background art where existing traditional rotary paper suction mechanisms typically rely on complex guide rail systems to guide the flipping trajectory of the suction cups for one-by-one paper mold delivery. However, the guide rails wear down under repeated flipping, causing the guide grooves to enlarge and the flipping trajectory to deviate. Severe deviation can lead to paper mold delivery failure. The design of this invention eliminates the need for guide rails, simplifying the mechanical structure and eliminating concerns about guide rail wear. Through the combination of a centrifugal wheel and a force-applying linkage, the flipping component performs a reciprocating fan-shaped oscillation, thereby achieving one-by-one placement of the paper molds.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A guide rail-free single-rotation paper suction mechanism includes:

[0008] conveyor;

[0009] The fixing frame is provided on both sides of the conveyor belt;

[0010] A rotating shaft, which is laterally inserted into the fixed frame;

[0011] The rocker arm is provided in two parts, with one end of each rocker arm sleeved onto the shaft of the rotating shaft.

[0012] A flipping rod, the two ends of which are respectively hinged to two rocker plates, and the flipping rod pivotally supports a rotating shaft;

[0013] A suction cup is disposed on the body of the flipping rod, and the suction cup is perpendicular to the extension direction of the rocker.

[0014] A flipping component, the top end of which is sleeved onto one end of a force-applying connecting rod;

[0015] The force-applying link is arranged laterally, and one end of the force-applying link is movably connected to the bottom end of the flipping component;

[0016] The centrifugal wheel has its non-axial surface connected to the other end of the force-applying connecting rod. The centrifugal wheel drives the flipping component to complete reciprocating fan-shaped oscillation through the force-applying connecting rod.

[0017] include

[0018] The number of the turning links corresponds to the rocker. The turning end of any one of the turning links is hinged to the fixed frame, and the force-applying end and both ends of the turning link are hinged to the other end of the corresponding rocker.

[0019] Also includes:

[0020] Mounting brackets, two of which are mounted side by side in the extension direction of one side of the fixing bracket;

[0021] The bottom end of the feeding guide is fixedly connected to the two mounting brackets, and the feeding guide is set at an angle;

[0022] A transmission rod, the two ends of which pass through the two mounting brackets;

[0023] Driven wheel, the shaft of which is sleeved on the body of the transmission rod;

[0024] A drive motor is located directly below the driven wheel;

[0025] A drive wheel, which is sleeved on the output end of the drive motor;

[0026] A drive belt, the two ends of which are sleeved on the outer surfaces of the drive wheel and the driven wheel.

[0027] The turning link has a V-shaped structure with a turning angle of 100°-140°.

[0028] The suction cups are provided in multiple ways.

[0029] The suction cups are arranged at equal intervals along the axial direction of the flipping rod, and the spacing is adapted to the diameter of the paper cup mold.

[0030] The centrifugal wheel is fixedly installed at one end of the transmission rod.

[0031] Compared with existing technologies, the advantages of this invention are: The design eliminates the need for guide rails, simplifying the mechanical structure and eliminating concerns about guide rail wear. The combination of a centrifugal wheel and a force-applying linkage enables the flipping component to reciprocate in a fan-shaped oscillation, thus achieving the sequential placement of the paper molds. The V-shaped structure of the turning linkage effectively limits the flipping angle, ensuring the smoothness and precision of the flipping motion and avoiding potential misoperation or equipment damage caused by excessive movement. This not only reduces the complexity of the equipment but also lowers maintenance costs, eliminating concerns about the need for regular adjustment or replacement of the slide rail system.

[0037] 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.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] like Figure 1-3 As shown, this utility model provides a railless single-rotation paper suction mechanism, which includes a conveyor belt 1, a fixed frame 2, a rotating shaft 3, a rocker 4, a flipping rod 5, a suction cup 6, a flipping component 7, a force-applying connecting rod 8, and a centrifugal wheel 9.

[0040] Fixed frames 2 are located on both sides of the conveyor belt 1, and rotating shafts 3 are transversely inserted through the fixed frames 2. The fixed frames 2, located on both sides of the conveyor belt 1, ensure the stability and positioning of the entire structure. The function of the rotating shaft 3 is to serve as a central axis, connecting various moving parts and providing rotational support, allowing the rocker 4 and suction cup 6 to rotate around the rotating shaft 3. The rotating shaft 3 provides a fulcrum for rotation, while the presence of the fixed frames 2 ensures the overall stability and accuracy of the system.

[0041] In this embodiment, two rocker arms 4 are provided. One end of each rocker arm 4 is sleeved on the shaft of the rotating shaft 3. The rocker arms 4 are designed to connect with the rotating shaft 3 so that the suction cup 6 can be flipped by the action of the flipping rod 5. The two ends of the flipping rod 5 are respectively hinged to the two rocker arms 4, and the flipping rod 5 pivotally supports the rotating shaft 3. The rocker arms 4 can perform flipping motion under the support of the rotating shaft 3. The rocker arms 4 realize the rotation operation of the suction cup 6 through the connection with the flipping rod 5. The two ends of the flipping rod 5 are hinged to the rocker arms 4, so that the rocker arms 4 can drive the flipping rod 5 to reciprocate. By flipping the rocker arms 4, the suction cup 6 can be controlled to adsorb and release the paper cup mold.

[0042] In this embodiment, suction cup 6 is disposed on the body of the flipping rod 5. The extension direction of suction cup 6 and rocker plate 4 is perpendicular. Multiple suction cups 6 are disposed and are arranged equidistantly along the axial direction of flipping rod 5. The suction cup 6 flips back and forth by the rotation action of flipping rod 5, which can effectively adsorb paper cup mold and accurately place it on conveyor belt 1 with each rotation.

[0043] In this embodiment, the spacing is adapted to the diameter of the paper cup mold. The top of the flipping component 7 is sleeved on one end of the force-applying connecting rod 8. The force-applying connecting rod 8 is arranged laterally, with one end movably connected to the bottom end of the flipping component 7. The non-axial surface of the centrifugal wheel 9 is connected to the other end of the force-applying connecting rod 8. The centrifugal wheel 9 drives the flipping component 7 to complete reciprocating fan-shaped oscillation through the force-applying connecting rod 8. The centrifugal wheel 9 is fixedly installed on one end of the transmission rod 13. The centrifugal wheel 9 and the drive motor 15 work together in the transmission system to provide rotational power, which is transmitted through the combination of the drive wheel 16, belt, and driven wheel 14. The flipping component 7 is used to realize the reciprocating motion of the entire mechanism, while the force-applying connecting rod 8 is used to drive the flipping component 7 to oscillate through the centrifugal wheel 9. The force-applying connecting rod 8 drives the reciprocating motion of the flipping component 7 through the rotation of the centrifugal wheel 9. The force-applying connecting rod 8 connects to the centrifugal wheel 9 and drives the movement of the flipping component 7 through its rotation. The centrifugal wheel 9 provides an effective way to control the movement of the flipping component 7, thereby affecting the action of the suction cup 6.

[0044] In this embodiment, the number of deflecting links 10 corresponds to the rocker arm 4. The deflecting end of any deflecting link 10 is hinged to the fixed frame 2, and the force-applying end and both ends of the deflecting link 10 are hinged to the other end of the corresponding rocker arm 4. The deflecting link 10 has a V-shaped structure with a deflection angle of 100°-140°. The deflecting link 10 effectively controls the rotation amplitude of the rocker arm 4 through its V-shaped structure, limiting the rotation angle of the rotating shaft 3 and preventing excessive movement from affecting the stability of the mechanism. The deflecting link 10 works in conjunction with the rocker arm 4; as the rocker arm 4 rotates, it drives the movement of the deflecting link 10, controlling the rotation angle through its own deflection shape. This ensures the coordinated work of the rocker arm 4 and the rotating shaft 3 while preventing loss of control due to excessive movement angles.

[0045] Two mounting brackets 11 are provided, installed side by side on one side of the fixed frame 2 along its extension direction. The bottom end of the feeding guide rail 12 is fixedly connected to the two mounting brackets 11. The feeding guide rail 12 is angled. Both ends of the transmission rod 13 pass through the two mounting brackets 11. The shaft of the driven wheel 14 is sleeved on the body of the transmission rod 13. The drive motor 15 is located directly below the driven wheel 14. The drive wheel 16 is sleeved on the output end of the drive motor 15. Both ends of the transmission belt 17 are sleeved on the outer surfaces of the drive wheel 16 and the driven wheel 14. The mounting brackets 11 support the feeding guide rail 12, ensuring that the paper cup mold can be accurately guided to the suction cup 6. The feeding guide rail 12 acts as a guiding device, helping to smoothly transport the paper cup mold and avoid jamming. The feeding guide rail works in conjunction with the mounting brackets 11. The angled arrangement of the feeding guide rail 12 ensures that the paper cup mold can be smoothly transported to the suction cup 6 area, allowing the suction cup 6 to successfully adhere and place it.

[0046] It should be noted that the guide rail-less single-rotation paper suction mechanism designed in this utility model, when in use, starts the flipping motor, the output end of the motor rotates and drives the drive wheel 16, the drive wheel 16 drives the driven wheel 14 through the belt, the driven wheel 14 rotates and drives the transmission rod 13, the transmission rod 13 rotates axially and drives the centrifugal wheel 9, the centrifugal wheel 9 rotates and drives one end of the force-applying connecting rod 8 which is movably connected to the wheel surface, the movement of one end of the force-applying connecting rod 8 will cause the other end to move as well, the other end of the force-applying connecting rod 8 drives the bottom end of the flipping component 7, the centrifugal wheel 9 rotates one revolution, thus driving the flipping component 7 to reciprocate fan-shaped flipping back and forth. The rotation of the bottom end of the flipping component 7 drives the top rotating shaft rod 3 to rotate axially, the rotation of the rotating shaft rod 3 drives the two rocker arms 4 of the rod body to rotate, the two rocker arms 4 rotate and drive the flipping rod 5, the flipping rod 5 rotates and drives the suction cup 6 of the rod body to rotate back and forth, the suction cup 6 in the flipping movement will attract the paper cup mold on the feeding guide rail 12 and flip it to place it on the conveyor belt 1 below. The whole process does not require the guidance of the flipping trajectory by the arc or vertical slide rail. The turning link 10 will be driven to rotate along with the rocker arm 4. Due to its own turning shape and the fact that the turning link 10 and the rotating shaft 3 are both set on the fixed frame 2, the turning link 10 will effectively limit the rotation angle of the rotating shaft 3 through the rocker arm 4, so that its reciprocating motion range is not too large.

[0047] 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 may 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.
