Description

Technical Field

[0001] This utility model belongs to the technical field of sealing and cutting mechanisms for sealing machines, and particularly relates to a quick-assembly and disassembly independent sealing and cutting mechanism. Background Technology

[0002] A disposable cup sealing machine is a device specifically designed to seal the opening of disposable cups. It mainly uses heating or pressurization to tightly bond the cup opening to the sealing film, thus achieving a seal.

[0003] Existing sealing machines have several drawbacks. For example, during daily use, it's necessary to frequently clean foreign objects from the bottom of the sealing head to ensure its cleanliness. Traditional heating head mechanisms are secured to the upper mounting plate with screws and bolts. Disassembling one cutter or heating head requires disassembling the entire mechanism for maintenance, a cumbersome and time-consuming process that significantly impacts production speed. Furthermore, the existing heating head and cutter mechanisms are integrated, making it impossible to independently adjust the flatness and downward pressure of any single heating head or cutter, resulting in unsatisfactory sealing and cutting effects. Therefore, we propose a quick-assembly and disassembly independent sealing and cutting mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a quick-assembly and disassembly independent sealing and cutting mechanism to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a quick-assembly and disassembly independent sealing and cutting mechanism, including an upper fixing plate, several power cords, and several heating strips, and further including:

[0006] A plurality of limiting strips are inserted into the bottom of the upper fixed plate. An independent sealing transition plate is fixedly installed at the bottom of each of the limiting strips. A plurality of fixing posts are fixedly installed at the top of the upper fixed plate. A limiting post is threaded into each of the fixing posts. The lower ends of the limiting posts are respectively inserted into and engaged with the plurality of limiting strips.

[0007] A plurality of fixed frames are respectively arranged directly below a plurality of independent sealing and cutting transition plates. Each of the plurality of fixed frames is provided with an independent toothed cutter. Each of the plurality of independent toothed cutters is provided with a copper hot-pressing head. A plurality of power lines are respectively fixedly installed in a plurality of copper hot-pressing heads. A plurality of heating strips are respectively inserted into a plurality of copper hot-pressing heads. The plurality of power lines are respectively electrically connected to a plurality of heating strips. Two fixing strips are arranged below the upper fixing plate and on both sides of the plurality of fixed frames. Limiting rollers are rotatably installed in both of the fixing strips.

[0008] A plurality of fixing components are located on a plurality of independent sealing and cutting transition plates and are used to fix a plurality of fixing frames, a plurality of independent toothed cutters and a plurality of copper hot-pressing heads;

[0009] Two sets of limiting components are provided, both of which are located on the upper fixing plate and are used to fix the positions of the two fixing strips.

[0010] In this technical solution, when the entire device is in use, electricity is transmitted to two heating bars through the power cord. The two heating bars heat the bottom of the copper hot-pressing head, which can press the plastic film to be sealed and heat it to a molten state, so that the material is bonded to form a sealing edge. Then, several fixed frames and several copper hot-pressing heads are pressed upward. The fixed frames and several copper hot-pressing heads are all displaced upward. Then, several third high-temperature resistant springs and several second high-temperature resistant springs are compressed and contracted. Then, the independent toothed cutter can squeeze and cut the plastic film to ensure that the plastic film can cover the cup. Finally, the fixed frames and several copper hot-pressing heads are released. Under the action of the rebound force of several third high-temperature resistant springs and several second high-temperature resistant springs, the independent toothed cutter and the fixed frames are displaced downward and reset.

[0011] When the entire device needs to be disassembled, several fixed frames, several independent toothed cutters, and several copper hot-press heads can be removed through the fixed components. The operator uses tools to rotate several limiting posts, which disengage from several limiting strips. Then, several independent sealing and cutting transition plates can be pulled out from the upper fixed plate. The fixed components can also remove two fixing strips, which facilitates the disassembly of one of the fixed frames, independent toothed cutters, and copper hot-press heads. It also allows for quick changes in the specifications and dimensions of packaging materials, making it suitable for multiple product specifications and reducing the customer's packaging costs.

[0012] Meanwhile, the tools can be used to adjust the flatness and downward pressure of each individual toothed cutter and the copper hot-press head, which greatly reduces the defect rate of packaged products and saves customers time in daily equipment maintenance and setup.

[0013] In the above technical solution, the fixing component further includes:

[0014] A plurality of third plug bolts are slidably installed in an independent sealing transition plate. The lower ends of the plurality of third plug bolts extend into the fixed frame, and the plurality of third plug bolts are threadedly connected to the fixed frame. A third high-temperature resistant spring is fitted on the plurality of third plug bolts.

[0015] A plurality of second plug bolts are slidably installed in an independent sealing transition plate. The lower ends of the plurality of second plug bolts extend into a copper hot-press head, and the plurality of second plug bolts are threadedly connected to the copper hot-press head. A second high-temperature resistant spring is fitted on each of the plurality of second plug bolts.

[0016] A plurality of fixing rods are fixedly installed on the top of the independent toothed cutter, and each of the fixing rods is threaded with screws that are slidably connected to the independent sealing and cutting transition plate.

[0017] In this technical solution, when the overall device needs to be disassembled, firstly, several third-stage bolts are rotated using tools, and the bolts are disengaged from several fixed frames. Then, the fixed frames are removed. Next, several screws are rotated using tools, and the screws are disengaged from several fixed rods. Then, several independent toothed cutters can be removed. Next, several second-stage bolts are rotated using tools, and the bolts are disengaged from several copper hot-pressed heads. Finally, the copper hot-pressed heads are removed. Then, the operator rotates several limiting posts using tools, and the limiting posts are disengaged from several limiting strips. Finally, several independent sealing and cutting transition plates are pulled out from the upper fixed plate.

[0018] In the above technical solution, the limiting component further includes:

[0019] Two first plug bolts are slidably installed inside the upper fixing plate. The lower ends of the two first plug bolts extend into the fixing strip, and the two first plug bolts are threadedly connected to the fixing strip. A first high-temperature resistant spring is fitted on each of the two first plug bolts.

[0020] In this technical solution, the worker uses a tool to rotate the four first locking bolts, and the four first locking bolts are respectively disengaged from the two fixing strips. Then the worker can remove the two fixing strips.

[0021] In the above technical solution, furthermore, two fourth plug bolts are fixedly installed on the copper hot-pressed end caps, and the bottom ends of the fourth plug bolts are respectively in contact with the heating strips.

[0022] In this technical solution, the positions of several heating strips can be fixed by setting several fourth bolts.

[0023] In the above technical solution, furthermore, a plurality of fixing blocks are fixedly installed on the upper fixing plate, and the plurality of fixing blocks are respectively located on one side of a plurality of independent sealing and cutting transition plates, and the plurality of fixing blocks are respectively in close contact with the plurality of independent sealing and cutting transition plates.

[0024] In this technical solution, the installation positions of several independent sealing and cutting transition plates can be pre-positioned by setting several fixing blocks.

[0025] In the above technical solution, the cross-section of the limiting strip is trapezoidal.

[0026] In this technical solution, it is ensured that the limiting strip can slide back and forth at the bottom of the upper fixed plate without falling off.

[0027] In the above technical solution, furthermore, a handle is fixedly installed on one side of each of the aforementioned independent sealing transition plates.

[0028] In this technical solution, a handle is provided to facilitate the removal of the independent sealing and cutting transition plate by the staff.

[0029] The beneficial effects of this utility model are:

[0030] 1. This quick-assembly and disassembly independent sealing and cutting mechanism allows for the removal of several fixed frames, several independent toothed cutters, and several copper hot-pressing heads by means of a fixed assembly. Workers can then use tools to rotate several limiting posts, which disengage from several limiting strips. Finally, several independent sealing and cutting transition plates can be pulled out from the upper fixed plate. The limiting assembly also allows for the removal of two fixing strips, facilitating the disassembly of one of the fixed frames, independent toothed cutters, and copper hot-pressing heads. It also allows for quick changes in packaging material specifications and sizes, making it suitable for multiple product specifications and reducing packaging costs for customers.

[0031] 2. This quick-assembly and disassembly independent sealing and cutting mechanism allows for adjustment of the position of the second and third stopper bolts using tools. This adjustment enables the leveling and downward pressure of each independent toothed cutter and the copper hot-pressing head, significantly reducing the defect rate of packaged products and saving customers time on daily equipment maintenance and setup.

It can also quickly change the specifications and dimensions of the packaging material, which is suitable for multiple specifications of products and reduces the packaging costs for customers.

[0050] Meanwhile, the flatness and downward pressure of each independent toothed cutter 6 and the copper hot-press head 7 can be adjusted through the tool, which greatly reduces the defect rate of packaged products and saves customers' daily maintenance and adjustment time for the equipment.

[0074] The handle 20 allows staff to easily pull out the independent sealing and cutting transition plate 3.

[0075] Working principle: When the whole device is in use, electricity is transmitted to the two heating bars 9 through the power cord 8. The two heating bars 9 heat the bottom of the copper hot-press head 7. The copper hot-press head 7 can press the plastic film to be sealed and heat it to a molten state, so that the material is bonded to form a sealing edge. Then, several fixed frames 5 and several copper hot-press heads 7 are pressed upward. Several fixed frames 5 and several copper hot-press heads 7 are all displaced upward. Then, several third high-temperature resistant springs 17 and several second high-temperature resistant springs 15 are compressed and contracted.

Then, use a tool to rotate several fourth-stage bolts 19, causing them to detach from the copper hot-press heads. Within 7, several heating strips 9 can be removed. The operator uses tools to rotate several limiting posts 4, which detach from several limiting strips 2. Then, several independent sealing and cutting transition plates 3 can be pulled out from the upper fixed plate 1. The operator uses tools to rotate four first plug bolts 12, which detach from two fixed strips 10. The operator can then remove the two fixed strips 10 to facilitate the disassembly of one of the fixed frames 5, the independent toothed cutter 6, and the copper hot-pressing head 7. This also allows for quick changes in the specifications and dimensions of the packaging material, making it suitable for multiple product specifications and reducing the customer's packaging costs.
