Description

Technical Field

[0001] This utility model belongs to the technical field of blister sealing machines, and specifically relates to a blister sealing machine. Background Technology

[0002] A blister sealing machine is an industrial machine that uses pulse heating principle to select different current outputs and energizing times according to the size of the workpiece or the heat sealing area, and then completes the heat sealing packaging under cooling and pressurization. It is mainly used for heat sealing packaging of blister packs and paper cards, and is suitable for blister sealing packaging of various exquisite toys, stationery, batteries, food, daily necessities, and small tools, making the packaged items moisture-proof, crystal clear and beautiful, and improving the grade of the products.

[0003] For example, CN 220333152 U discloses a blister sealing machine, which relates to the field of sealing machines. It includes a worktable, a sealing machine body, a sealing assembly, and a rotating assembly. The rotating assembly includes a circular groove, an arc block, a rotating plate, a rotating shaft, a turbine, a servo motor, and a worm gear. The other end of the worm gear is rotatably connected to the inner wall of the worktable. The worm gear meshes with the turbine. This utility model can drive the rotation of the worm gear through the drive of the servo motor. The rotation of the worm gear can drive the rotation of the turbine, and the rotation of the turbine can drive the rotation of the rotating shaft, which in turn drives the rotation of the rotating plate. By setting the rotation angle of the servo motor, the lower mold on the rotating plate can be automatically stopped after rotating 90 degrees, so that it can be sealed by the sealing assembly. By setting multiple lower molds, the work efficiency can be improved. The lower molds can be replaced by setting dovetail grooves and dovetail blocks, making it more convenient to use.

[0004] Although the mold in the above case is fixed by dovetail grooves and dovetail blocks, the connection is not stable enough and the disassembly and assembly are not simple enough. Utility Model Content

[0005] The purpose of this invention is to provide a blister sealing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blister sealing machine, including a base, a rotating disk rotatably connected to the top of the base, a connecting component on the top of the rotating disk, four molds clamped to the top of the rotating disk via the connecting component, a side frame on one side of the base, and a heat pressing component at the top of the side frame.

[0007] In a preferred embodiment, a drive motor is fixedly connected to one side of the top of the device base, a drive gear is fixedly connected to the output shaft of the drive motor, and annular internal teeth that mesh with the drive gear are provided on the inner wall of the bottom of the rotating disk.

[0008] In a preferred embodiment, the connecting assembly includes four annularly spaced connecting cavities on the top of the rotating disk, each connecting cavity having slide rails on both sides, and an "H"-shaped connecting frame slidably connected to the outside of the four slide rails.

[0009] In a preferred embodiment, guide rails are provided on both sides of the bottom of the connecting cavity, and sliding sleeves are slidably connected to the outside of the guide rails. Connecting plates are rotatably connected to both sides of the sliding sleeves, and the other ends of the two connecting plates are rotatably connected to one side of the connecting frame.

[0010] In a preferred embodiment, the guide rail has a groove inside, a guide post is fixedly connected inside the groove, the sliding sleeve is slidably connected to the outside of the guide post, and a spring sleeved on the outside of the guide post is fixedly connected between one end of the sliding sleeve and one end of the inner cavity of the groove.

[0011] In a preferred embodiment, the connecting frame has four connecting slots inside, and each mold has four connecting parts at the bottom that are adapted to the connecting slots. The bottom end of each connecting part has a tapered part, and the interior of each connecting part has an elliptical deformation cavity. Damping blocks are provided on both sides of the bottom of the connecting frame.

[0012] In a preferred embodiment, the hot pressing assembly includes a hydraulic lifting rod fixedly connected to the bottom of the side frame above the rotating disk, and a hot pressing plate is provided at the bottom end of the hydraulic lifting rod.

[0013] In a preferred embodiment, the rotary table has four stations around its perimeter. The station located below the hot press plate is the working station, one side of the working station is the unloading station, one side of the unloading station is the loading station, and one side of the loading station is the waiting station.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This blister sealing machine uses a tapered connector to fit the mold into a connecting groove for quick positioning. Combined with the elastic deformation characteristics of the deformation cavity, users can easily install or remove the mold with a simple push, without the need for additional tools, which greatly improves the mold change rate.

[0016] In this blister sealing machine, when the hot pressing component applies pressure to the mold, the sliding sleeve slides along the guide post and compresses the spring. The elastic deformation of the spring absorbs part of the impact force, preventing the pressure from being directly transmitted to the fixed parts of the connecting frame and the rotating disk. The movement of the sliding sleeve drives the connecting frame to finely adjust its position through the connecting plate, making the mold more evenly stressed and reducing local stress.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-5 This utility model provides a blister sealing machine, including a base 1, a rotating disk 6 rotatably connected to the top of the base 1, a drive motor 5 fixedly connected to one side of the top of the base 1, a drive gear 501 fixedly connected to the output shaft of the drive motor 5, and annular internal teeth 601 meshing with the drive gear 501 on the inner wall of the bottom of the rotating disk 6. The rotating disk 6 has four work stations around its perimeter. The work station is located below the hot press plate 4, one side of the work station is the unloading station, one side of the unloading station is the loading station, and one side of the loading station is the waiting station. When the drive motor 5 is started, the drive gear 501 on its output shaft drives the annular internal teeth 601 at the bottom of the rotating disk 6 to rotate, thereby causing the rotating disk 6 to rotate on the top of the base 1.

[0026] The rotary table 6 rotates 90° each time, switching the mold 7 to different workstations in sequence. The rotary table 6 has four workstations: waiting workstation, loading workstation, unloading workstation, and working workstation. When the mold 7 is in the waiting workstation, it waits for the loading instruction. When it rotates to the loading workstation, the operator puts the blister pack and cardboard to be sealed into the mold 7. Then it rotates to the working workstation to perform the sealing operation. Finally, it rotates to the unloading workstation, where the operator takes out the sealed product.

[0027] In this embodiment, a connecting assembly is provided on the top of the rotating disk 6. Four molds 7 are secured to the top of the rotating disk 6 via the connecting assembly. The connecting assembly includes four annularly distributed connecting cavities 602 on the top of the rotating disk 6. Each connecting cavity 602 has slide rails 603 on both sides of its inner cavity. An "H"-shaped connecting frame 604 is slidably connected to the outside of the four slide rails 603. Guide rails 606 are provided on both sides of the bottom of the inner cavity of the connecting cavity 602. Sliding sleeves 607 are slidably connected to the outside of the guide rails 606. Connecting plates 608 are rotatably connected to both sides of the sliding sleeves 607. The other ends of the two connecting plates 608 are connected to the connecting frame 604. The guide rail 606 is rotatably connected to one side. A sliding groove is opened inside the guide rail 606. A guide post is fixedly connected inside the sliding groove. The sliding sleeve 607 is slidably connected to the outside of the guide post. A spring sleeved on the outside of the guide post is fixedly connected between one end of the sliding sleeve 607 and one end of the inner cavity of the sliding groove. The connecting frame 604 has four connecting grooves 605 inside. Each mold 7 has four connecting parts 701 at the bottom that are adapted to the connecting grooves 605. The bottom end of the connecting part 701 has a tapered part 702. An elliptical deformation cavity 703 is opened inside the connecting part 701. Damping blocks 6051 are provided on both sides of the bottom of the connecting frame 604.

[0028] The operator aligns the four connecting parts 701 at the bottom of the mold 7 with the connecting grooves 605 of the "H"-shaped connecting frame 604 in the connecting cavity 602 on the rotating disk 6. Since the bottom of the connecting part 701 is provided with a tapered part 702, the tapered part 702 plays a guiding role during the insertion process, making it easier for the connecting part 701 to enter the connecting groove 605. At the same time, the elliptical deformation cavity 703 inside the connecting part 701 will undergo slight deformation when squeezed, further facilitating the insertion. When the connecting part 701 is fully inserted into the connecting groove 605, the tapered part 702 returns to its shape, thus locking the mold 7.

[0029] When the mold 7 is subjected to the pressure of the hot press plate 4, the connecting frame 604 is simultaneously subjected to downward pressure, which drives the connecting plate 608 to rotate, thereby pushing the sliding sleeve 607 to slide along the guide post in the guide rail 606, compressing the spring. The elastic potential energy of the spring increases, which can play a buffering role during hot pressing.

[0030] In this embodiment, a side frame 2 is provided on one side of the equipment base 1, and a hot pressing assembly is provided at the top of the side frame 2. The hot pressing assembly includes a hydraulic lifting rod 3 fixedly connected to the bottom of the side frame 2 above the rotating disk 6. A hot pressing plate 4 is provided at the bottom of the hydraulic lifting rod 3. When the mold 7 rotates to the working position (located below the hot pressing plate 4), the hydraulic lifting rod 3 is activated, pushing the hot pressing plate 4 downward to hot press and seal the blister pack and cardboard in the mold 7. The temperature of the hot pressing plate 4 and the downward pressure of the hydraulic lifting rod 3 can be adjusted according to different workpiece sizes or heat sealing areas to ensure sealing quality. After the hot pressing and sealing is completed, the hydraulic lifting rod 3 drives the hot pressing plate 4 to rise and return to the initial position.

[0031] The working principle and usage process of this utility model are as follows: First, the operator aligns the four connecting parts 701 at the bottom of the mold 7 with the connecting groove 605 of the "H"-shaped connecting frame 604 in the connecting cavity 602 on the rotating disk 6. When the connecting part 701 is fully inserted into the connecting groove 605, the conical part 702 returns to its shape, thereby locking the mold 7.

[0032] When the drive motor 5 starts, the drive gear 501 on its output shaft drives the annular internal gear 601 at the bottom of the rotating disk 6 to rotate, thereby causing the rotating disk 6 to rotate on the top of the equipment base 1.

[0033] The rotary disk 6 rotates 90° each time, switching the mold 7 to different work stations in sequence. The rotary disk 6 has four work stations, namely the waiting work station, the loading work station, the unloading work station and the working work station. When the mold 7 is in the waiting work station, it waits for the loading command.

[0034] When the machine rotates to the loading station, the operator places the blister pack to be sealed and the cardboard into mold 7.

[0035] Then rotate to the working position, start the hydraulic lifting rod 3, push the hot press plate 4 to move downward, and perform hot pressing and sealing on the blister pack and paper card in the mold 7. The temperature of the hot press plate 4 and the downward pressure of the hydraulic lifting rod 3 can be adjusted according to different workpiece sizes or heat sealing areas to ensure sealing quality. After the hot pressing and sealing is completed, the hydraulic lifting rod 3 drives the hot press plate 4 to rise and return to the initial position.

[0036] When the mold 7 is subjected to the pressure of the hot press plate 4, the connecting frame 604 is simultaneously subjected to downward pressure, which drives the connecting plate 608 to rotate, thereby pushing the sliding sleeve 607 to slide along the guide post in the guide rail 606, compressing the spring. The elastic potential energy of the spring increases, which can play a buffering role during hot pressing.

[0037] Finally, the product is rotated to the unloading station, where the operator removes the sealed product.

[0038] It should be noted that the hot press plate 4 is existing publicly available technology, so it has not been described in detail.

[0039] 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 of the present invention, the scope of which is defined by the appended claims and their equivalents.
