Description

Technical Field

[0001] This utility model relates to an in-mold labeling device, specifically an injection-molded in-mold labeling yogurt cup production equipment. Background Technology

[0002] In the yogurt packaging production industry, traditional injection molding cup and label bonding processes suffer from low efficiency and poor bonding accuracy. With increasing market demands for packaging aesthetics and production automation, there is an urgent need for equipment that can simultaneously complete injection molding and label embedding. Existing in-mold labeling technology faces challenges in yogurt cup production, including inaccurate label positioning, label deformation due to high-temperature injection molding, and low equipment integration. Developing dedicated production equipment requires addressing key technologies such as label conveying, positioning, mold integration, and automated control to achieve efficient and precise in-mold labeling yogurt cup production. A Chinese patent (authorization announcement number CN 222346134 U) discloses an automatic in-mold labeling device for injection molding. This patented technology uses air vents to adsorb and position the in-mold label, featuring multiple cavities and air vents for simultaneous operation of multiple labels. It also includes a buffer device to prevent damage during mold closing. However, inconsistent air pressure can lead to problems. Excessive pressure results in numerous air holes on the label, while insufficient pressure weakens adsorption. Furthermore, the buffer device is overly simplistic, easily damaged, and ineffective. Therefore, those skilled in the art have developed an injection molding in-mold labeling yogurt cup production equipment to address the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a production equipment for yogurt cups with injection-molded film inner lining, so as to solve the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 In this embodiment of the utility model, a production equipment for injection-molded film-lined yogurt cups includes a housing 1. The inner wall of the left side panel of the housing 1 is provided with a fixed module 5, and the inner wall of the right side panel is provided with a second electric push rod 3. The second electric push rod 3 is connected to a moving module 8. The moving module 8 is equipped with four identical buffer rods 9. The inner wall of the rear panel of the housing 1 is provided with a first electric push rod 2. The first electric push rod 2 is connected to a limiting plate 11. A third electric push rod 4 is installed in the middle of the limiting plate 11. The left side of the third electric push rod 4 is connected to a film-applying module 6. The yogurt cup model on the film-applying module 6 is provided with an electrostatic ring 10. The right side of the third electric push rod 4 is connected to a finished product collection plate 7.

[0023] Specifically, the inner wall of the left side panel of the box body 1 is provided with a fixed module 5, which has six identical and symmetrical cup-shaped cavities 501 for injection molding of yogurt cups. The fixed module 5 has four identical guide holes 502 to facilitate precise mold closing of the two modules. The inner wall of the right side panel of the box body 1 is provided with a second electric push rod 3, which is connected to the moving module 8 and can control the left and right movement of the moving module 8. The moving module 8 has four identical buffer rods 9, which have a buffer inner rod 902 inside. The lower end of the buffer rod 9 has a buffer spring 901, and the upper end has a buffer pad 903 to buffer the process of mold closing of the two modules. The inner wall of the rear panel of the box body 1 is provided with a first electric push rod 2, which is connected to the limit... The positioning plate 11 is connected, and the middle of the limiting plate 11 is equipped with a third electric push rod 4. The left side of the third electric push rod 4 is connected to the film-applying module 6. The yogurt cup model on the film-applying module 6 is equipped with an electrostatic ring 10. Through the action of electrostatics, the inner film can be better adsorbed onto the yogurt cup model and is not easy to fall off. The lower side wall of the film-applying module 6 is equipped with a pulley 601. The right side of the third electric push rod 4 is connected to the finished product collection plate 7. The finished product collection plate 7 is equipped with six identical suction cups 701, which can be used to collect the yogurt cups after the injection molding film inner film has been applied. The lower side wall of the finished product collection plate 7 is equipped with a pulley of the same specification as the pulley 601. The lower side plate of the box 1 is equipped with a sliding groove 101. The pulley 601 and the pulley on the lower side wall of the finished product collection plate 7 are installed in the sliding groove 101, which can better perform positioning and sliding.

[0024] The working principle of this utility model is as follows: When using an injection molding film inlay production equipment, a fixed module 5 is provided on the inner wall of the left side panel of the housing 1. The fixed module 5 and the moving module 8 are in a separated state. The robotic arm grabs the inlay and passes it through the electrostatic ring 10 on the yogurt cup model on the film-applying module 6, adsorbing the inlay onto the film-applying module 6. The first electric push rod 2 is activated, and the first electric push rod 2 will move to the designated position according to the parameters set in advance in the PLC. At this time, the third electric push rod 4 is activated. The third electric push rod 4 pushes the film-applying module 6 to the left, causing it to adhere to the fixed module 5. The inner film sticker on the electrostatic ring 10 adheres to the inner wall of the cup-shaped cavity 501 of the fixed module 5, effectively preventing the inner film sticker from shifting or becoming loosely adhered due to external factors. The third electric push rod 4 is then activated to retract the film-applying module 6. The limiting plate 11 prevents excessive retraction. Simultaneously, the first electric push rod 2 retracts the entire module, while the second electric push rod 3 is activated, moving the module 8 and the fixed module 5. During the mold closing process, the buffer rod 9 on the moving module 8 is precisely inserted into the guide hole 502 on the fixed module 5, thereby achieving connection and positioning between the two modules. The lower end of the buffer rod 9 is equipped with a buffer spring 901, and the upper end is equipped with a buffer pad 903. When the buffer rod 9 enters the guide hole 502, the inner buffer rod 902 inside the buffer rod 9 will first contact the bottom of the guide hole 502, causing the inner buffer rod 902 to press downward, thereby further compressing the buffer spring 901 and the buffer pad 903. The elastic deformation generated by these components and the oily liquid in the cavity provide a buffering effect on the mold closing process, thereby avoiding vibration and impact caused by direct hard contact between the fixed module 5 and the moving module 8. This extends the service life of the device and further improves the accuracy of the mold assemblies. After the injection molding is completed, the yogurt cup with the injection-molded film attached can be picked up by the suction cup 701 on the finished product picking plate 7, realizing automated collection and improving production efficiency.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
