Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0042] Embodiment one

[0043] As shown in Figure 1 , Figure 2 , a desktop blister packaging machine comprises a frame 1, a molding and sealing lower die mechanism 2, a molding upper die mechanism 3, and a pressurizing and sealing mechanism 4 which can move up and down.

[0044] The molding and sealing lower die mechanism 2 is located below the frame 1, and has a molding and sealing position and an operating position, and can switch between the molding and sealing position and the operating position. In the operating position, the packaging material 51 can be placed into the molding and sealing lower die mechanism 2 by manual operation.

[0045] The molding upper die mechanism 3 is located in the middle of the frame 1, and has a molding working position and a molding exit position, and can switch between the molding working position and the molding exit position.

[0046] The pressurizing and sealing mechanism 4 is located above the frame 1. In other words, the height of the molding and sealing lower die mechanism 2 is below the height of the molding upper die mechanism 3, and the height of the molding upper die mechanism 3 is below the height of the pressurizing and sealing mechanism 4.

[0047] When the molding and sealing lower die mechanism 2 is in the molding and sealing position, and the molding upper die mechanism 3 is in the molding working position, the pressurizing and sealing mechanism 4 moves downward, driving the molding upper die mechanism 3 to move downward and contact the molding and sealing lower die mechanism 2, so as to realize the heating and molding function.

[0048] More specifically, when the molding and sealing lower die mechanism 2 is in the molding and sealing position, and the molding upper die mechanism 3 is in the molding working position, the packaging material 51 is placed on the molding and sealing lower die mechanism 2, the pressurizing and sealing mechanism 4 moves downward, driving the molding upper die mechanism 3 to move downward and contact the packaging material 51 and the molding and sealing lower die mechanism 2, and then pressure is applied, so as to realize the heating and molding function of the packaging material 51. In this embodiment, the packaging material 51 is a plastic sheet.

[0049] When the molding and sealing lower die mechanism 2 is in the molding and sealing position, and the molding upper die mechanism 3 is in the molding exit position, the pressurizing and sealing mechanism 4 moves downward and contacts the molding and sealing lower die mechanism 2, so as to realize the heating and sealing function.

[0050] More specifically, when the molding and sealing lower die mechanism 2 is in the molding and sealing position, and the molding upper die mechanism 3 is in the molding exit position, the cover material is placed on the molding and sealing lower die mechanism 2, and the heating and molding of the packaging material 51 on the molding and sealing lower die mechanism 2 has been completed. The cover material is placed on the packaging material 51, the pressurizing and sealing mechanism 4 moves downward, contacts the cover material, the packaging material 51 and the molding and sealing lower die mechanism 2, and then pressure is applied, so as to realize the heating and sealing function of the packaging material 51 and the cover material.

[0051] As can be seen from the above description, the molding and sealing position of the molding and sealing lower die mechanism 2 refers to that the molding and sealing lower die mechanism 2 is located directly below the pressurizing and sealing mechanism 4, the operating position of the molding and sealing lower die mechanism 2 refers to that it moves out from directly below the pressurizing and sealing mechanism 4; the molding working position of the molding upper die mechanism 3 refers to that the molding upper die mechanism 3 is located directly below the pressurizing and sealing mechanism 4 and directly above the molding and sealing lower die mechanism 2, and the molding exit position of the molding upper die mechanism 3 refers to that it moves out from directly below the pressurizing and sealing mechanism 4 and does not fall into the projection of the pressurizing and sealing mechanism 4, so as to avoid interference with the contact between the pressurizing and sealing mechanism 4 and the molding and sealing lower die mechanism 2.

[0052] The molding and sealing lower die mechanism 2 moves in the plane to realize the switching between the molding and sealing position and the operating position. The movement includes rotation of the molding and sealing lower die mechanism 2 in the plane to realize the switching between the molding and sealing position and the operating position, and also includes translation of the molding and sealing lower die mechanism 2 in the plane to realize the switching between the molding and sealing position and the operating position.

[0053] The upper mold mechanism 3 moves in a plane to switch between the forming position and the forming exit position. The movement includes rotation of the upper mold mechanism 3 in a plane to switch between the forming position and the forming exit position, and translation of the upper mold mechanism 3 in a plane to switch between the forming position and the forming exit position.

[0054] Therefore, the cooperation of the lower mold mechanism 2, the upper mold mechanism 3, and the pressing mechanism 4 realizes the forming and sealing functions of the table-type blister packaging machine in the same position, so that the packaging machine has a compact layout and a simplified structure, the forming and sealing temperature and time can be independently set, and the packaging quality is ensured.

Specifically, under the cooperation of the first driving mechanism 22 and the lower mold guide mechanism 21, the lower mold mechanism 2 rotates in a plane to switch between the forming and sealing position and the operating position.

[0056] The lower mold mechanism 2 further includes a lower mold mounting plate 235 below the lower mold 23, the lower mold body 231 is mounted on the lower mold mounting plate 235 and is connected by a mold positioning pin 234.

The upper mold forming 31 moves horizontally with the upper mold translation guide mechanism 32 driven by the second driving mechanism 34, and the upper mold up-down guide mechanism 33 moves horizontally with the upper mold translation guide mechanism 32. When a sufficient pressure is applied above the upper mold forming 31, the upper mold up-down guide mechanism 33 moves downward, and when the pressure is released, the upper mold forming 31 is reset by the spring 35. Of course, the spring 35 can also be other elastic mechanisms, which are not limited in particular.

[0058] The upper mold forming 31 includes an upper installation plate 312, a forming heating plate 311 below the upper installation plate 312, and a heating plate outer frame 313 around the forming heating plate 311.

[0060] A working method of a desktop blister packaging machine, comprising the following steps:

[0061] S1, the lower mold forming and sealing mechanism 2 is in the operating position, and the packaging material 51 is placed in the lower mold forming and sealing mechanism 2; the upper mold forming mechanism 3 is in the forming working position, and the forming heating plate 311 is heated to reach the set forming temperature, and the sealing pressure plate 411 of the pressure sealing mechanism 4 is heated to reach the set sealing temperature;

[0062] S2, the forming and sealing lower die mechanism 2 is switched from the operating position to the forming and sealing position, the pressurized sealing mechanism 4 is lowered to press the forming upper die mechanism 3 to contact the forming and sealing lower die mechanism 2, so that the packaging material 51 is heated to the forming temperature by the forming heating plate 311 and then stretched to a specific shape to realize the heating and forming function of the packaging material 51;

[0063] In the above step S2, the forming and sealing lower die mechanism 2 is supplied with compressed air so that the packaging material 51 is tightly attached to the forming cavity 237 of the forming and sealing lower die mechanism 2; or in the above step S2, the forming upper die mechanism 3 is supplied with compressed air so that the packaging material 51 is tightly attached to the forming cavity 237 of the forming and sealing lower die mechanism 2; of course, in the above step S2, blowing or vacuum suction can also realize the function of stretching the packaging material to a specific shape, and the specific implementation is not limited;

[0064] S3, after the heating and forming are completed, the forming upper die mechanism 3 is switched from the forming working position to the forming exit position, and the forming and sealing lower die mechanism 2 is switched from the forming and sealing position to the operating position, and then the cover material is placed above the packaging material 51 after the packaging object is put in;

[0065] S4, the forming and sealing lower die mechanism 2 is switched from the operating position to the forming and sealing position, the pressurized sealing mechanism 4 is lowered to contact the forming and sealing lower die mechanism 2 and apply pressure to realize the heating and sealing function of the cover material and the packaging material 51;

[0066] After the heating and sealing are completed, the pressurized sealing mechanism 4 is moved upward to reset;

[0067] S5, the forming and sealing lower die mechanism 2 is switched from the forming and sealing position to the operating position, and the completed packaging product is taken out.

[0068] Specifically, the working method of the utility model: the forming and sealing lower die mechanism 2 is in the manual operation position, the forming upper die mechanism 3 is in the forming working position, and the pressurizing and sealing mechanism 4 is in the rising position close to the top of the frame 1. The forming heating plate 311 and the sealing press plate 411 are heated to the set forming temperature and sealing temperature respectively by the electric heating tube 412. The person places the to-be-formed packaging material 51-plastic sheet on the forming and sealing lower die 23, and the packaging material positioning pin 233 is positioned. The operation button is used to drive the first driving mechanism 22 to move the forming and sealing lower die mechanism 2 to the forming and sealing position. At this time, the pressurizing and sealing mechanism 4 is driven to move the sealing press plate 411 downward to contact the forming upper die mechanism 3, and the sealing press plate 411 continues to be pressed downward until the heating plate outer frame 313 presses the packaging material 51-plastic sheet on the forming and sealing lower die 23 and the sealing strip 232 on the forming and sealing lower die 2. At this time, the first air vent 236 on the lower die mounting plate 235 is used to pass compressed air (the second air vent 314 is used to pass air), so that the packaging material 51-plastic sheet is tightly attached to the forming heating plate 311, and the forming heating plate 311 is heated to the forming temperature. The second air vent 314 on the upper mounting plate 312 is used to pass compressed air (at this time, the first air vent 236 is used to pass air), so that the heated packaging material 51-plastic sheet is stretched to the position in the forming cavity 237 of the forming and sealing lower die 23 under the action of compressed air. After the forming is completed, the pressurizing and sealing mechanism 4 is raised to reset, and the forming upper die 31 is reset by the spring 35. At this time, the forming upper die mechanism 3 is moved to the forming exit position under the action of the second driving mechanism 34. At the same time, the forming and sealing lower die mechanism 2 is moved to the manual operation position under the action of the first driving mechanism 22. At this time, the person places the packaging object into the bubble shell cavity in which the plastic sheet has been formed, and then places the cover material. The packaging material positioning pin 233 is positioned, the operation button is used to drive the first driving mechanism 22 to move the forming and sealing lower die mechanism 2 to the forming and sealing position. At this time, the pressurizing and sealing mechanism 4 is driven to move the sealing press plate 411 downward to directly press the cover material, the plastic sheet and the sealing strip 232 on the forming and sealing lower die 2. The sealing pressure and the sealing time can be controlled and set. After the sealing time, the pressurizing and sealing mechanism 4 is raised to reset the sealing press plate 411. At this time, the forming upper die mechanism 3 is moved to the forming working position again under the action of the second driving mechanism 34. At the same time, the forming and sealing lower die mechanism 2 is moved to the manual operation position again under the action of the first driving mechanism 22. The person takes out the packaged product, and then places the plastic sheet into the forming and sealing lower die 23 again. The above operation is repeated.

[0069] Embodiment Two

[0070] When the forming and sealing lower die mechanism 2 is switched between the forming and sealing position and the operation position, the rotating direction of the forming and sealing lower die mechanism 2 is not limited. When the forming upper die mechanism 3 is switched between the forming working position and the forming exit position, the rotating direction of the forming upper die mechanism 3 is also not limited.

[0071] As Figure 9 ,Figure 10 As shown, in this embodiment, the rotational translation direction of the lower forming and sealing mold mechanism 2 and the rotational movement direction of the upper forming mold mechanism 3 form a certain angle, which is 90° in this embodiment. This arrangement makes the overall space occupied by the tabletop blister packaging machine small.

[0072] Example 3

[0073] In Embodiment 1, the number of molding and sealing lower mold mechanisms 2 is one. For example... Figures 11-13 As shown, a tabletop blister packaging machine can be configured such that the forming and sealing lower mold mechanism 2 moves using a turntable 24, that is, the number of forming and sealing lower mold mechanisms 2 is two or more, which are equally installed on the turntable 24, and a load-bearing pad 28 is provided below the turntable 24.

[0074] Multiple sets of forming and sealing lower molds 23 are evenly installed on the turntable 24 and positioned and connected by mold positioning pins 234. The turntable 24 is fixedly connected to the rotating shaft 25 and has through holes corresponding to the first vent 236 of the forming and sealing lower mold 23. The rotating shaft 25 is axially fixed in the bearing housing 26 and can rotate radially. The bearing housing 26 is fixedly connected to the frame 1. The indexing driver 27 is connected to the bearing housing 26 and the rotating shaft 25, driving the turntable 24 to rotate at a set angle. When the forming and sealing lower mold 23 rotates to the forming and sealing position, it is exactly above the load-bearing pad 28. The load-bearing pad 28 is fixedly connected to the frame 1 and has a third vent 281 on it, which passes through the through hole on the turntable 24 and communicates with the first vent 236. When the pressure sealing mechanism 4 moves downward and contacts the forming and sealing lower mold 23, or when the forming upper mold mechanism 3 transmits pressure through the forming and sealing lower mold 231 and the turntable 24 to the load-bearing pad 28. The advantage of this layout is that it improves machine efficiency, and the molding and sealing time and manual operation time can overlap.

[0075] Example 4

[0076] like Figure 14 , Figure 15 As shown, a tabletop blister packaging machine can be configured to combine forming and sealing on a single movable plate 11, with the working mode switched by moving left and right. The frame 1 is movably equipped with the movable plate 11, and the forming upper mold mechanism 3 is mounted on the movable plate 11. When the movable plate 11 moves relative to the frame 1 in a plane, the forming upper mold mechanism 3 switches between the forming working position and the forming exit position.

[0077] When the forming and sealing lower die mechanism 2 is in the forming and sealing position, the forming upper die mechanism 3 is in the right position, the pressurizing and sealing mechanism 4 goes down, drives the forming upper die 31 to go down and contact with the plastic sheet and the forming and sealing lower die 23, and applies a certain pressure, realizes the heating forming function of the plastic sheet. When the forming upper die mechanism 3 is in the left position, the pressurizing and sealing mechanism 4 goes down, drives the sealing die 41 to go down and contact with the cover material, the plastic sheet and the forming and sealing lower die 23, and applies a certain pressure, realizes the heating sealing function of the plastic sheet and the cover material. The advantage of this layout is that the moving stroke of the forming and sealing cylinder is reduced, the gas consumption is greatly reduced, the machine operation efficiency is improved, and the moving stroke of the forming and sealing cylinder is consistent.

[0078] The above specific embodiment is used to explain and illustrate the present application, rather than limit the present application, any modification and change made to the present application within the spirit and protection scope of the claims of the present application, falls into the protection scope of the present application.
