Description

Technical Field

[0001] This utility model relates to the field of packaging production technology, and in particular to a product packaging device. Background Technology

[0002] Currently, the product packaging process typically requires a nitrogen-filled packaging glove box. Drying sheets are used to absorb residual water and oxygen molecules in the product. Specifically, the packaging glove box is equipped with a turntable on which a raw material strip is wound. After the raw material strip is unwound from the turntable, it is conveyed to the material handling platform. Under the action of the material handling mechanism, individual drying sheets are transferred into the packaging cover so that they can absorb residual water and oxygen molecules in the product after the product is pressed and packaged.

[0003] When packaging products in the same batch, the number of desiccant sheets is often more than the number of products, in case of unforeseen circumstances. Therefore, after packaging products in the same batch, there are often desiccant sheets left over. Since the desiccant sheets are easily exposed to water and oxygen molecules in the atmosphere and become ineffective after being removed from the packaging glove box, an adsorption mechanism is often used to transfer the desiccant sheets to a vacuum environment for sealing. The whole process is quite cumbersome and costly.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a product packaging device to improve the sealing efficiency of the remaining desiccant sheets after the product is packaged.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A product packaging device includes a first material tray and a material picking platform. The first material tray is used for winding and unwinding a raw material strip. Drying sheets are evenly distributed on one side of the raw material strip. Along the unwinding direction of the raw material strip, the material picking platform is located downstream of the first material tray, and the material picking platform is directly opposite the side of the raw material strip that is away from the drying sheets.

[0008] The product packaging device further includes:

[0009] The second material tray is located upstream of the material taking platform and is used to unwind the sealing film tape. The portion of the sealing film tape in the material taking platform area is parallel to the raw material tape, and a pressure-sensitive adhesive layer is provided on one side of the sealing film tape, with the pressure-sensitive adhesive layer facing the drying sheet.

[0010] A pressing mechanism is positioned opposite the material handling platform. The pressing mechanism cooperates with the material handling platform to press the sealing film strip and the raw material strip together, and to seal the drying sheet.

[0011] A winding mechanism, located downstream of the material handling platform, is used to wind up the raw material strip with the sealing film tape pressed onto it.

[0012] Preferably, the pressing mechanism includes:

[0013] A lifting component is positioned above the material handling platform;

[0014] A pressure head is disposed at the lifting end of the lifting component, and the lifting component is used to drive the pressure head closer to or away from the material handling platform.

[0015] Preferably, the pressing mechanism further includes a pressing unit, which protrudes from the side of the pressing head facing the material taking platform, and the outer contour of the pressing unit is similar to the outer contour of the drying sheet.

[0016] Preferably, there are multiple pressing units, and the multiple pressing units are arranged in rows and / or columns.

[0017] Preferably, the pressure head is detachably mounted on the lifting member.

[0018] Preferably, the product packaging device further includes a first redirection section, which is disposed on the upstream side of the material handling platform. The first redirection section is used to adjust the unwinding direction of the raw material strip and the sealing film strip so that the raw material strip and the sealing film strip are arranged in parallel.

[0019] Preferably, the first redirecting section includes a plurality of redirecting rollers, which are rotatable around their own axes, and the raw material belt and the sealing film belt are stacked in parallel after passing around the same redirecting roller.

[0020] Preferably, two limiting rings are provided at intervals on the circumferential wall of any of the redirecting rollers, and the distance between the two limiting rings is adapted to the width of the raw material belt and the width of the sealing film belt.

[0021] Preferably, the winding mechanism includes a servo motor and a take-up tray, the take-up tray being disposed at the output end of the servo motor, and the servo motor being used to drive the take-up tray to rotate intermittently.

[0022] Preferably, the product packaging device further includes a second redirection section, which is disposed on the upstream side of the take-up tray and is used to adjust the winding direction of the raw material strip with the sealing film tape pressed on it.

[0023] The beneficial effects of this utility model are:

[0024] In this product packaging device, after the product packaging is completed, when sealing the remaining dry sheets, the first tray continues to unwind the raw material tape, and the second tray begins to unwind the sealing film tape. The unwound raw material tape and sealing film tape can be arranged parallel to each other in the area of ​​the picking platform. Based on the characteristics of pressure-sensitive adhesive, the raw material tape and sealing film tape are pressed together with the cooperation of the pressing mechanism and the picking platform, thereby sealing the dry sheets. With this setup, the sealing of the dry sheets can be completed without transferring them, thanks to the sealed environment inside the packaging glove box, thus improving the sealing efficiency of the dry sheets.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] Please see Figures 1 to 3 This embodiment proposes a product packaging device, which includes a first material tray 1, a material picking platform 2, a second material tray 3, a pressing mechanism 4, and a winding mechanism 5. The first material tray 1 is used for winding and unwinding a raw material strip 100. Drying sheets are evenly distributed on one side of the raw material strip 100. Along the unwinding direction of the raw material strip 100, the material picking platform 2 is located downstream of the first material tray 1, and the material picking platform 2 is directly opposite the side of the raw material strip 100 that is away from the drying sheets. The second material tray 3 is located upstream of the material picking platform 2 and is used for unwinding. A sealing film strip 200 is provided, with the portion of the sealing film strip 200 located in the area of ​​the material handling platform 2 being parallel to the raw material strip 100. A pressure-sensitive adhesive layer is provided on one side of the sealing film strip 200, and the pressure-sensitive adhesive layer is directly opposite the drying sheet. A pressing mechanism 4 is directly opposite the material handling platform 2 and is used to cooperate with the material handling platform 2 to press the sealing film strip 200 and the raw material strip 100 together and seal the drying sheet. A winding mechanism 5 is located on the downstream side of the material handling platform 2 and is used to wind up the raw material strip 100 with the sealing film strip 200 pressed on it.

[0040] Understandably, after the product is packaged, when sealing the remaining desiccant sheets, the first tray 1 continues to unwind the raw material tape 100, and the second tray 3 begins to unwind the sealing film tape 200. The unwound raw material tape 100 and sealing film tape 200 can be arranged parallel to each other in the area of ​​the pick-up platform 2. Based on the characteristics of the pressure-sensitive adhesive, the raw material tape 100 and sealing film tape 200 are pressed together with the pressing mechanism 4 and the pick-up platform 2, thereby sealing the desiccant sheets. With this setup, the sealing of the desiccant sheets can be completed without transferring them, thanks to the sealed environment inside the packaging and patching glove box, thus improving the sealing efficiency of the desiccant sheets.

[0041] In this embodiment, the pressing mechanism 4 includes a lifting component and a pressing head 41. The lifting component is positioned above the material handling platform 2; the pressing head 41 is located at the lifting end of the lifting component, and the lifting component drives the pressing head 41 to move closer to or away from the material handling platform 2. It is understood that the material handling platform 2, the raw material belt 100, the sealing film belt 200, and the pressing head 41 are arranged sequentially along the height direction. Under the action of the lifting component, the pressing head 41 can move closer to the sealing film belt 200 and push the sealing film belt 200 towards the raw material belt 100, thereby pushing the sealing film belt 200 and the raw material belt 100 towards the material handling platform 2 to press the raw material belt 100 and the sealing film belt 200 together, while simultaneously sealing the dried sheet. The lifting component is preferably a lifting structure such as a lifting cylinder.

[0042] Furthermore, the pressing mechanism 4 also includes a pressing unit 42, which protrudes from the pressing head 41 towards the material handling platform 2. The outer contour of the pressing unit 42 is similar to the outer contour of the drying sheet. It is understood that during the movement of the raw material belt 100, the pressing unit 42 can be directly opposite the drying sheet. Under the action of the driving component, the pressing unit 42 can move towards the drying sheet. During this process, the sealing film belt 200 can move closer to the raw material belt 100, and under the action of the pressing unit 42, the pressure-sensitive adhesive located around the drying sheet can bond to the raw material belt 100, thereby completing the sealing of the drying sheet. Preferably, the outline shape of the pressing unit 42 is square.

[0043] Furthermore, multiple pressing units 42 are provided, and the multiple pressing units 42 are arranged in rows and / or columns. It can be understood that the arrangement shape of the pressing units 42 is consistent with the arrangement shape of the drying sheets, so that multiple drying sheets can be sealed at the same time to improve the sealing efficiency of the drying sheets.

[0044] Furthermore, during the product packaging process, a material-grabbing mechanism is used to pick up individual drying sheets. Specifically, the material-grabbing mechanism includes a driving component and an adsorption component. The driving component is used to drive the adsorption component to move closer to or away from the drying sheet. To reduce the production cost of the product packaging device, in this embodiment, the lifting component and the driving component are of the same structure; that is, the pressure head 41 is detachably mounted on the lifting component. It can be understood that when it is necessary to seal the drying sheet, the adsorption head can be replaced with the pressure head 41, thereby changing the material-grabbing action of the material-grabbing mechanism to the pressing action of the pressing mechanism 4. This configuration avoids the need for an additional driving component, thereby reducing production costs.

[0045] In this embodiment, the product packaging device further includes a first redirecting section 6, which is disposed upstream of the material handling platform 2. The first redirecting section 6 is used to adjust the unwinding direction of the raw material strip 100 and the sealing film strip 200 so that the raw material strip 100 and the sealing film strip 200 are arranged in parallel. It can be understood that after the raw material strip 100 and the sealing film strip 200 are unwound, they are conveyed to the material handling platform 2 after passing through the first redirecting section 6, and under the action of the first redirecting section 6, the raw material strip 100 and the sealing film strip 200 can be arranged in parallel to each other to facilitate subsequent pressing.

[0046] Specifically, the first redirecting section 6 includes a plurality of redirecting rollers 61, which are rotatable around their own axes. The raw material belt 100 and the sealing film belt 200 are stacked after passing over the same redirecting roller 61. It can be understood that during the release process, the raw material belt 100 and the sealing film belt 200 can pass through the plurality of redirecting rollers 61 to facilitate alignment of the raw material belt 100 and the sealing film belt 200, thereby ensuring accuracy in the subsequent pressing process and improving the sealing quality of the drying sheet.

[0047] For example, the redirecting roller 61 is provided with a material strip 100 released from the first material tray 1 that can extend to the redirecting roller 61 and through the redirecting roller to the pressing mechanism 4, and a sealing film strip 200 released from the second material tray 3 that can extend to the redirecting roller 61 and through the redirecting roller to the pressing mechanism 4. This arrangement facilitates the stacking of the material strip 100 and the sealing film strip 200 at the redirecting roller 61, so that the pressing mechanism 4 can press the two together, thereby further improving the sealing quality of the drying sheet.

[0048] For example, multiple redirecting rollers 61 are provided, and the multiple redirecting rollers 61 are divided into a first redirection, a second redirection, and a third redirection. The third redirection is provided on the upstream side of the pressing mechanism 4. The first redirection is provided between the first material tray 1 and the third redirection to adjust the unwinding direction of the raw material strip 100. The second redirection is provided between the second material tray 3 and the third redirection to adjust the unwinding direction of the sealing film strip 200. During the extension process, at the third redirection, the raw material strip 100 and the sealing film strip 200 can be arranged in parallel stacks. This arrangement can improve the applicability of the product packaging device.

[0049] It should be noted that the number of reversing rollers 61 in the first, second, and third reversing operations depends on the actual working scenario and will not be elaborated here.

[0050] Furthermore, two limiting rings 62 are spaced apart on the circumferential wall of any of the redirecting rollers 61, and the distance between the two limiting rings 62 is adapted to the width of the raw material strip 100 and the width of the sealing film strip 200. It is understood that during transportation, the two limiting rings 62 can limit the movement of the raw material strip 100 and the sealing film strip 200, thereby preventing them from becoming stuck during transportation and further improving the sealing quality of the product packaging device.

[0051] In this embodiment, the winding mechanism 5 includes a servo motor and a take-up tray. The take-up tray is located at the output end of the servo motor, and the servo motor drives the take-up tray to rotate intermittently. It is understood that the servo motor is electrically connected to the pressing mechanism 4. During the downward pressing of the pressing head 41, the servo motor stops rotating; during the upward pressing of the pressing head 41, the servo motor starts rotating, thereby enabling the material strip 100 and the sealing film strip 200 to move, thus completing the sealing of the next dried sheet. This arrangement avoids damage to the dried sheet during the downward pressing of the pressing head 41, further improving the sealing performance of the product packaging device.

[0052] In this embodiment, the product packaging device further includes a second redirecting section 7, which is located upstream of the take-up tray and is used to adjust the winding direction of the raw material strip 100 with the sealing film strip 200 pressed on it. This configuration allows for changing the position of the winding mechanism 5 according to the actual application scenario, thereby further improving the applicability of the product packaging device.

[0053] It should be noted that the second reversing unit 7 has the same structure as the first reversing unit 6, and will not be described in detail here.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
