Description
Technical Field
[0001] This utility model relates to the field of molds, and in particular to an in-mold labeling mechanism for a wine jug. Background Technology
[0002] like Figure 1 The image shows a common wine flask, which is generally produced using a blow molding process. To improve production efficiency, an in-mold labeling method is used during the blow molding process to attach the label to the outer wall of the flask.
[0003] Due to the symmetry of the wine jug, in order to reduce the production cost of the mold, the cavities in the two halves of the mold are exactly the same. In this way, in the traditional mold, the label can only be placed on the inner wall of the cavity of the half mold. Then, the mold is closed by the drive mechanism. As a result, the label is located on one side of the wine jug handle. Since the area of this position is small, the area of the label is also small, which makes it impossible for the label to display enough product information. Therefore, it is necessary to propose an in-mold labeling mechanism for wine jugs to solve the above technical problems. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose an in-mold labeling mechanism for wine jugs, so as to solve the technical problem in the prior art that when wine jugs are labeled by in-mold labeling, the label can only be located on one side of the handle of the wine jug. Since the area of this position is small, the area of the label is also small, which makes it impossible for the label to display sufficient product information.
[0005] To achieve the above objectives, this utility model provides an in-mold labeling mechanism for a wine jug, used for in-mold labeling during the blow molding process. The mold has at least one cavity, and the top of the mold has a feed inlet communicating with the cavity. The mold includes two symmetrical half-molds, and a clamping plate is fixed to the outer side of each half-mold. The clamping plate is connected to a drive mechanism for opening and closing the two half-molds. The cavity includes a first cavity for forming the jug body and a second cavity for forming the jug handle. A labeling area is formed on the side wall of the first cavity opposite to the second cavity. A through hole is provided on the outer side of the mold, penetrating the labeling area. The in-mold labeling mechanism for the wine jug further includes:
[0006] A film-applying block slidably connected to the through hole, wherein the sidewall of the film-applying block facing the cavity is an arc shape that matches the first cavity, for attaching labels;
[0007] A drive unit used to drive the film block to slide within the through hole.
[0008] Furthermore, the driving component is a telescopic cylinder fixed to one of the half molds, and the output shaft of the telescopic cylinder is fixedly connected to the film-applying block.
[0009] Furthermore, the mold cavity is provided in two parts, and the second part of the two mold cavities is arranged opposite to each other.
[0010] Furthermore, the telescopic cylinders corresponding to the two cavities are fixed on different half molds.
[0011] Furthermore, the through hole has a side groove on the inner wall of the half mold of the fixed telescopic cylinder, and the film-applying block has a side block that is slidably connected to the side groove.
[0012] Furthermore, the clamping plate is provided with clamping components for holding the wine pot. The clamping components include an upper limit plate and a lower limit plate disposed on the inner side of the clamping plate. The upper limit plate is located directly above the lower limit plate. After the mold is closed, the clamping components form clamping areas that correspond one-to-one with the cavity. In the clamping areas, the opposite upper limit plate is used to clamp the head position of the wine pot, and the opposite lower limit plate is used to clamp the bottom position of the wine pot.
[0013] Furthermore, the distance between the two cavities is equal to the distance between the two clamping areas.
[0014] The beneficial effects of this utility model are as follows: Using the in-mold labeling mechanism of this utility model for a wine jug, after the mold is opened by the drive mechanism, the two half-molds are in a separated state. A robotic arm attaches the label to the side of the film-applying block facing the first cavity. Then, the drive mechanism closes the mold. After mold closure, the drive unit drives the film-applying block to move a certain distance towards the cavity, making the arc-shaped side of the film-applying block flush with the inner wall of the cavity. Finally, the raw material is blow-molded into the cavity through the feed inlet, completing the production of the wine jug. During production, the label on the film-applying block will be pasted onto the wine jug. After the two half-molds of the mold are opened a certain distance, the drive unit drives the film-applying block to move away from the cavity, causing the label to separate from the film-applying block. In this device, since the labeling area is directly opposite the second cavity forming the wine jug handle, a larger label can be used to more completely display product information on the label.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0026] The first aspect of this utility model proposes an in-mold labeling mechanism for a wine jug, such as... Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this is used for in-mold labeling during blow molding. The mold has at least one cavity 11, and the top of the mold has a feed port 3 communicating with the cavity 11. The mold includes two symmetrical half-molds 2. A clamping plate 1 is fixed to the outside of the half-molds 2. The clamping plate 1 is used to connect with a drive mechanism that drives the two half-molds 2 to open and close. The cavity 11 includes a first cavity for forming the body of the wine bottle and a second cavity for forming the handle of the wine bottle. A labeling area is formed on the side wall of the first cavity opposite to the second cavity. A through hole 6 is provided on the outer side of the mold to penetrate the labeling area. The in-mold labeling mechanism for the wine bottle also includes:
[0027] The film-applying block 5 is slidably connected to the through hole 6. The side wall of the film-applying block 5 facing the cavity 11 is an arc shape that matches the first cavity, and is used to apply labels.
[0028] A drive unit for driving the film block 5 to slide within the through hole 6.
[0029] In this embodiment, after the mold is opened by the drive mechanism, the two half-molds 2 are in a separated state. The label is attached to the side of the film-applying block 5 facing the first cavity by the robot arm. Then, the mold is closed by the drive mechanism. After the mold is closed, the drive unit drives the film-applying block 5 to move a certain distance towards the cavity 11, so that the arc-shaped side of the film-applying block 5 is flush with the inner wall of the cavity 11. Finally, the raw material is blow-molded into the cavity 11 through the feed port 3 to complete the production of the wine bottle. During the production process, the label on the film-applying block 5 will be pasted on the wine bottle. After the two half-molds 2 are opened a certain distance, the drive unit drives the film-applying block 5 to move away from the cavity 11, so that the label is separated from the film-applying block 5. In this device, since the labeling area is directly opposite the second cavity that forms the handle of the wine bottle, a larger label can be used to display product information more completely on the label. The drive mechanism can be a hydraulic cylinder or a pneumatic cylinder to drive the two half-molds 2 to open or close. In addition, this structure only requires modification of the existing wine jug mold, without the need to create a new mold, which greatly saves modification costs.
[0030] As one implementation method, such as Figure 2 , Figure 4 As shown, the driving component is a telescopic cylinder 4 fixed on one of the half molds 2. The output shaft of the telescopic cylinder 4 is fixedly connected to the film-applying block 5. The telescopic cylinder 4 can be a hydraulic cylinder or a pneumatic cylinder.
[0031] In addition, such as Figure 2 , Figure 5 As shown, there are two cavities 11, and the second cavity in the two cavities 11 is arranged opposite to each other. The production speed can be greatly improved by using the two cavities 11.
[0032] Ideally, such as Figure 2 , Figure 4As shown, the telescopic cylinders 4 corresponding to the two cavities 11 are fixed on different half molds 2, so that the half molds 2 are subjected to the same external force, so as to prevent the cavities 11 from being misaligned due to the different external forces on the half molds 2.
[0033] As one implementation method, such as Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the through hole 6 has a side groove 12 on the inner wall of the half mold 2 of the fixed telescopic cylinder 4, and the film-applying block 5 has a side block that is slidably connected to the side groove 12. Here, by limiting the side block and the side groove 12, it can be ensured that the film-applying block 5 moves simultaneously with the corresponding half mold 2 during the movement of the two half molds 2, making the film-applying block 5 more stable.
[0034] As one implementation method, such as Figure 2 , Figure 3 , Figure 4 As shown, the clamping plate 1 is provided with clamping components for clamping the wine pot. The clamping components include an upper limit plate and a lower limit plate disposed on the inner side of the clamping plate 1. The upper limit plate is located directly above the lower limit plate. After the mold is closed, the clamping components form clamping areas that correspond one-to-one with the cavities 11. In the clamping areas, the opposite upper limit plates are used to clamp the head position of the wine pot, and the opposite lower limit plates are used to clamp the bottom position of the wine pot.
[0035] In this embodiment, after the mold is opened, the produced wine pot is fixed by a robotic arm and moved to the clamping area. Then the mold is closed again, and the wine pot is fixed by the upper limit plate and the lower limit plate. After completion, the flash on the outside of the wine pot is removed by a cutting blade.
[0036] Here, the distance between the two cavities 11 is equal to the distance between the two clamping areas. In this way, after the mold is opened, the robot arm can simultaneously clamp the two cavities and move to the corresponding clamping areas, which can reduce the complexity of the mechanical structure.
[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
[0038] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
