Description

Technical Field

[0001] This invention relates to the field of paper cup production technology, and specifically to a paper cup handle attaching machine that automatically attaches handles to the outside of paper cups. Background Technology

[0002] The purpose of a paper cup handle attaching machine is to automatically attach handles to the outside of paper cups. Existing technologies, such as the paper cup handle attaching machine with patent number 200910099681.0 and patent name "Paper Cup Handle Attaching Machine", have a turntable 2 installed horizontally, and the pressing strip 12 of the pressing device is installed on the turntable 2 and rotates synchronously with the turntable. Therefore, the drive component that controls the movement of the pressing strip of the pressing device has a very complex structure. If a pneumatic method is used, the drive component requires a complex air distribution device and pipeline design, resulting in high operating noise and inconvenient installation and maintenance. If an electrical control method is used, the drive component requires a complex electrical circuit design such as slip rings and brushes, resulting in a complex operating structure and many failures. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a high-speed paper cup handle attaching machine that can achieve high-speed paper cup handle attaching production with a simple structure.

[0004] This invention is accomplished using the following technical solution:

[0005] A high-speed paper cup handle attaching machine includes a main turntable that rotates in an indexing manner during operation. The main turntable is vertically mounted, and its outer circumference is sequentially arranged with a cup-attaching station, a handle-attaching station, and a cup-dispensing station. A cup mold is mounted on the main turntable for each station, and a pressure head is located beside each cup mold. The pressure head is mounted on the upper end of a swing arm, which is oscillatingly connected to the main turntable in the middle. A roller is connected to the lower end of the swing arm. An independently rotatable main control cam is located on the outer side of the main turntable. The disc is equipped with a cam groove to allow the roller to move within it. The main control cam disc is driven by a control drive to perform reciprocating circular oscillation. During operation, the main control cam disc oscillates once in coordination with the main turntable for each rotation of one station. At the upper station, when the main turntable pauses intermittently, the main control cam disc oscillates forward at a certain circular angle before the main turntable, so that the pressure head contacts the cup mold. Then the main turntable continues to rotate in increments. When the main control cam disc returns to its original position, the pressure head maintains contact with the cup mold until it leaves the cup handle and is close to the station.

[0006] Multiple cup handles are installed close to the workstation.

[0007] The main turntable is fixedly connected to the main shaft, and the main control cam disk is movably sleeved on the outer circle of the main shaft. The control drive component includes a pull rod, one end of which is connected to the main control cam disk, and the other end is pushed by the first transmission cam.

[0008] The upper handle station is equipped with a handle forming and conveying component, which includes a roll paper feeding mechanism. During operation, the roll paper fed by the roll paper feeding mechanism is pulled by the front traction mechanism, die-cut by the die-cutting mechanism, pulled by the rear traction mechanism, and cut by the cross-cutting mechanism. The handle is formed independently and falls onto the receiving platform. The receiving platform is equipped with grippers on both sides. The grippers reciprocate in the front and back direction to send the handle to the upper handle station.

[0009] A hot air blowing component is installed above the receiving platform to heat the handle by blowing air, and multiple sets of grippers are installed in front and behind.

[0010] The gripper is mounted on the slide, and the slide moves back and forth driven by the second transmission cam.

[0011] The first and second transmission cams are fixedly installed on the same transmission shaft of the sticking machine's transmission mechanism.

[0012] A paper cup circumferential alignment station is provided between the cup-up station and the handle-up station. A circumferential alignment component and a color mark probe are provided corresponding to the paper cup circumferential alignment station. The circumferential alignment component includes a rotating pressure sleeve, which is connected to the output end of a servo motor. The servo motor is movably arranged along the radial direction of the main turntable. The servo motor is electrically connected to the color mark probe. The cup mold is rotatably mounted on the main turntable.

[0013] The paper cup circumferential alignment station is provided with two.

[0014] The high-speed paper cup handle attaching machine described above features a vertically mounted main turntable with an independently rotatable main control cam disc on its outer side. This main control cam disc is driven by a simple control drive component, such as a first transmission cam, to reciprocate in a circular motion. During intermittent pauses of the main turntable, the main control cam disc can oscillate forward before the turntable. Thus, when the main turntable pauses at the handle attachment position, although the pressure head is still far from the cup mold (facilitating handle insertion), the main control cam disc will oscillate forward in a circular motion. By swinging the cam at a certain circumferential angle, the curve of the cam groove at the upper handle station changes in advance without the main turntable moving, causing the swing arm to swing and thus bringing the pressure head into contact with the cup mold. The main turntable then continues its indexing rotation. During the indexing rotation from the upper handle station to the cup dispensing station, the paper cup and handle maintain close contact for a longer period. This ensures reliable contact between the paper cup and handle even at high speeds on the main turntable, thus achieving high-speed production of paper cups with handles with a simple structure, without requiring the complex gas distribution or electrical circuit designs required by existing technologies or published patents. However, in the above-described process, during the swing of the cam to bring the pressure head into contact with the cup mold, the effective circumferential angle of the main control cam must be smaller than the indexing rotation angle of the main turntable. Otherwise, when the main turntable indexes to the next station after the upper handle station, the return swing of the main control cam would cause the pressure head to lose contact with the cup mold again, which is unacceptable. Furthermore, before attaching the paper cup to the handle, a circumferential alignment station is set up. By adjusting the movement of the circumferential alignment component, the seam line on the outer circle of the paper cup can maintain a uniform position in the circumferential direction before reaching the handle station, ensuring the accurate placement of the handle on the paper cup and guaranteeing the aesthetics and quality of the handle attachment.

[0021] like Figure 1As shown, the paper cup with a handle produced by the present invention consists of a paper cup N and a handle M, with the handle M being glued and fixed to one side of the outer circle of the paper cup N.

[0022] like Figure 2-5 As shown, the high-speed paper cup handle attaching machine of the present invention includes a main turntable 1 that rotates in an indexing manner during operation. The main turntable 1 is vertically installed and fixedly connected to the main shaft 13. The outer circle of the main turntable 1 is arranged with twelve stations in sequence, including cup loading station A, paper cup circumferential alignment station B, handle attaching station C, handle attaching station D, and cup dispensing station E. There are two paper cup circumferential alignment stations B and four cup handle attaching stations D. A cup mold 3 is installed on the main turntable 1 corresponding to each station. The cup mold 3 is rotatably mounted on the main turntable 1. A pressure head 4 is provided on the side of each cup mold 3. The pressure head 4 is mounted on the upper part of the swing arm 5. At one end, the swing arm 5 is oscillatingly connected to the main turntable 1 via the swing shaft 6. The lower end of the swing arm 5 is connected to the roller 14. The outer side of the main turntable 1 is provided with an independently rotatable main control cam disk 2. The main control cam disk 2 is movably sleeved on the outer circle of the main shaft 13. The main control cam disk 2 is provided with a cam groove 15 to allow the roller 14 to be movably disposed therein. The main control cam disk 2 is driven by a control drive component to perform reciprocating circular oscillation. The control drive component includes a pull rod 7. One end of the pull rod 7 is connected to the main control cam disk 2, and the other end is driven by the first transmission cam 8 through the swing arm 11. Of course, the control drive component can also be a servo motor. In the aforementioned high-speed paper cup handle attaching machine, during operation, the main turntable 1 rotates 30 degrees for each station. The main control cam plate 2 reciprocates in a circular motion once, with the swing angle being less than 30 degrees. If it is greater than 30 degrees, the effective circular swing angle for pushing the pressure head to contact the cup mold at the upper handle station C must also be less than 30 degrees. At the upper handle station C, when the main turntable 1 pauses intermittently, the main control cam plate 2 swings forward a certain circular angle before the main turntable 1 to make the pressure head 4 contact the cup mold 3. Then, the main turntable 1 continues to rotate in increments. When the main control cam plate 2 returns to its original position, the pressure head 4 maintains contact with the cup mold 3 until it leaves all four cup handles and is attached to the work station D.

[0023] Corresponding to the cup-feeding station A, there is a spiral cup-feeding component A1. When the spiral cup-feeding component A1 is working, it places the paper cup N onto the cup mold 3. Corresponding to the paper cup circumferential alignment station B, there is a circumferential alignment component and a color mark probe. The color mark probe is used to detect the position of the seam line or the color mark position on the outer circle of the paper cup. The circumferential alignment component includes a rotating pressure sleeve B1, which is connected to the output end of a servo motor B2. The servo motor B2 is set to move along the radial direction of the main turntable 1. The servo motor B2 is electrically connected to the color mark probe. When the paper cup reaches the paper cup circumferential alignment station, the color mark probe detects the position of the seam line or the color mark position on the outer circle of the paper cup, and then controls the rotating pressure sleeve to approach and press the bottom of the cup. At the same time, the servo motor rotates, causing the paper cup to rotate by a corresponding angle, so that the seam line on the outer circle of the paper cup reaches a uniform position. Corresponding to the handle-feeding station C, there is a handle forming and conveying component. The handle forming... The conveying components include a roll paper feeding mechanism. During operation, the roll paper fed by the roll paper feeding mechanism is pulled by the front traction mechanism C1, die-cut by the die-cutting mechanism C2, pulled by the rear traction mechanism C3, and cut by the cross-cutting mechanism C4. The handle M is formed independently and falls onto the receiving platform C5. The receiving platform C5 is provided with grippers C6 on both sides. There are three sets of grippers C6 in the front and back. The grippers C6 are installed on the slide C7. The grippers C6 reciprocate in the front and back direction to send the handle M to the upper handle station C. The front and back movement of the slide C7 is pushed by the second transmission cam 9 through the rocker arm 12. The first transmission cam 8 and the second transmission cam 9 are fixedly installed on the same transmission shaft 10 of the handle attaching machine transmission mechanism. There are two sets of hot air blowing components C8 above the receiving platform C5 to blow air and heat the handle M so that the handle M and the paper cup N stick together.

[0024] The invention works as follows: The main turntable 1 rotates in twelve equal divisions, each rotation being 30 degrees circumferentially. During intermittent pauses at the cup-feeding station A, the spiral cup-feeding component A1 places the paper cup N onto the cup mold 3. During intermittent pauses at the paper cup circumferential alignment station B, the circumferential alignment component ensures the seam line of the outer circumference of the paper cup N on the cup mold reaches a uniform circumferential position. During intermittent pauses at the handle-feeding station C, the handle-forming and conveying component forms the handle M and, after heating it with air, delivers it to the lower side of the paper cup N via the gripper C6. At this time, the rotation of the first transmission cam 8 pushes the main control cam disk 2 forward circumferentially via the pull rod 7. The change in the curve of the cam groove 15 of the main control cam disk 2 causes the swing arm 5 to swing, thus the pressure head 4 contacts the cup mold 3. The pressure head 4 attaches the handle adhesive M to the lower side of the paper cup N, bonding the handle M to the paper cup N. The main turntable 1 continues its indexing rotation... Afterwards, the first transmission cam 8 pushes the main control cam disk 2 to swing back to its original position via the pull rod 7. Since the circumferential angle of the indexing rotation of the main turntable 1 is greater than the effective circumferential angle of the circumferential swing of the main control cam disk 2, the return of the main control cam disk 2 will not cause the swing arm 5 to swing back. Thus, the pressure head 4 and the cup mold 3 continue to maintain contact. In the subsequent multiple cup handle attaching stations D, the pressure head 4 and the cup mold 3 remain in contact, so that the paper cup N and the handle M can maintain close contact for a longer period of time. Then, after leaving all the cup handle attaching stations D, the cam groove curve of the main control cam disk 2 changes, causing the swing arm 5 to swing, causing the pressure head 4 to return to its original position. The pressure head 4 disengages from the cup mold 3. At the cup exit station E, the cup mold 3 blows air to blow the paper cup with the attached handle off the cup mold and is then sucked away by the cup exit pipe. The simple structure completes the high-speed production of paper cup handle attaching while ensuring the aesthetics and quality of the product.
