In addition, in the following description, when referring to the accompanying drawings, the same marks in different drawings represent the same elements. Those skilled in the art should understand that the above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.
[0026] According to an exemplary embodiment of the present disclosure, referring to Figures 1 to 5 As shown, a film pressing mechanism is provided, which includes a base 1, a pressing roller 2 and an adjusting component. The pressing roller 2 is arranged on the base 1 and is used to press and fix the film on the surface of the product to be coated; the adjusting component is arranged between the base 1 and the pressing roller 2 and includes a first adjusting component 3 and a second adjusting component. The first adjusting component 3 is used to adjust the position of the pressing roller 2 in a first direction, and the second adjusting component is used to adjust the inclination angle of the pressing roller 2 in a second direction, wherein the second direction intersects with the first direction.
[0027] Through the above technical scheme, in the film pressing mechanism disclosed in the present invention, the film is placed in the gap between the pressing roller 2 and the product to be coated, and the film is pressed to the surface of the product by the pressing roller 2 to complete the coating, and the coating effect is good and automatic coating can be achieved. The film pressing mechanism is provided with an adjustment component between the base 1 and the pressing roller 2, that is, by providing a first adjustment component 3 to adjust the height of the pressing roller 2 in the first direction, so as to adjust the size of the gap between the pressing roller 2 and the product to be coated, so as to achieve coating operations on products of different sizes, and has a wide range of applications. By providing a second adjustment component to adjust the inclination angle of the pressing roller 2 in the second direction, for example, the extension direction of the pressing roller 2 can be perpendicular to the conveying direction of the film, so as to ensure the flatness of the film when passing through the pressing roller 2, and further ensure the coating quality and coating efficiency.
[0028] It should be noted here that the reference Figure 1As shown, the first direction (L1 direction), the second direction (L2 direction) and the third direction (L3 direction) may intersect each other. In some embodiments of the present disclosure, the first direction, the second direction and the third direction are perpendicular to each other. Below, the present disclosure is only exemplified by taking the first direction, the second direction and the third direction as an example.
[0029] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the two ends of the pressing roller 2 in the axial direction are respectively mounted on the base 1 through the mounting blocks 5, and each mounting block 5 is provided with a first adjustment component 3 and a second adjustment component. In this way, the height and inclination of the two ends of the pressing roller 2 can be adjusted by the first adjustment component 3 and the second adjustment component on each mounting block 5 to ensure the laminating effect and laminating efficiency. In addition, arranging the first adjustment component and the second adjustment component on the mounting block can also improve the integration of the laminating mechanism.
[0030] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the laminating mechanism also includes a second mounting block 7, which is connected to the base 1. The first adjusting component 3 includes an elastic member 31 and a locking mechanism. The elastic member 31 is arranged between the base 1 and the corresponding mounting block 5, and one end of the elastic member 31 is connected to the base 1, and the other end is connected to the corresponding mounting block 5; the locking structure includes a first locking member 32 and a second locking member, and the second locking member is arranged on the second mounting block 7. The first locking member 32 can be movably matched with the second locking member along the first direction, and the end of the first locking member 32 abuts against the corresponding mounting block 5.
[0031] refer to Figure 1 and Figure 2As shown, the base 1 includes two first parts 11 arranged in parallel and a second part 12 perpendicular to the two first parts 11, the second mounting block 7 is arranged on the corresponding first part 11, the elastic member 31 is arranged between the second part 12 and the mounting block 5, one end of the elastic member 31 is connected to the second part 12, and the other end is connected to the mounting block 5, and the elastic member 31 and the second locking member of the locking mechanism are respectively arranged on both sides of the mounting block 5. In this way, when the first locking member 32 moves along the first direction relative to the second locking member on the second mounting block 7, the end of the first locking member 32 can abut against the mounting block 5, so that the mounting block 5 moves along the first direction. Specifically, when the first locking member 32 moves downward relative to the second mounting block 7 along the first direction, the end of the first locking member 32 can push the mounting block 5 to move downward, at this time, the elastic member 31 is further compressed, and the gap between the pressure roller 2 and the product to be coated is gradually reduced. When the first locking member 32 is fixed relative to the second mounting block 7, the height of the mounting block 5 is also fixed, and the gap between the pressure roller 2 and the product to be coated is also fixed. When the first locking member 32 moves up along the first direction relative to the second mounting block 7, the end of the first locking member 32 moves upward, and the mounting block 5 moves upward under the elastic action of the elastic member 31, and the gap between the pressure roller 2 and the product to be coated gradually increases. When the first locking member 32 is fixed relative to the second mounting block 7, the height of the mounting block 5 is also fixed, and the gap between the pressure roller 2 and the product to be coated is also fixed. It should be understood that the elastic member 31 between the second part 12 and the mounting block 5 is elastic, that is, the elastic member 31 between the second part 12 and the mounting block 5 is always in a compressed state. The position of the first locking member 32 is locked by the second locking member, so that the height of the pressure roller 2 can be adjusted while ensuring the working stability of the pressure roller 2 after the height adjustment.
[0032] In some embodiments of the present disclosure, reference Figure 2 As shown, the mounting block 5 is provided with a height adjustment hole 52 with an opening, and the height adjustment hole 52 is formed with a bottom wall at one end away from the opening, and the elastic member 31 is at least partially located in the height adjustment hole 52, and one end is connected to the base 1, and the other end is abutted against the bottom wall. The elastic member 31 is partially placed in the height adjustment hole 52, and the elastic member 31 applies an elastic force to the bottom wall to make the mounting block 5 move along the first direction, so as to generate a buffering effect on the movement of the mounting block 5 along the first direction, thereby ensuring the stability of the mounting block 5 during the movement process. At the same time, the elastic member 31 is arranged in the height adjustment hole 52 to prevent the elastic member 31 from shifting relative to the mounting block 5, thereby ensuring the stability of the mounting block 5 during the movement process.
[0033] In some embodiments of the present disclosure, reference Figure 1 and Figure 2As shown, the first adjustment component 3 further includes a guide structure 33, and the guide structure 33 includes a guide hole 332 and a guide column 331 capable of guiding the matching, one of the guide hole 332 and the guide column 331 is arranged on the base 1, and the other is arranged on the mounting block 5. The extending direction of the guide column 331 and the guide hole 332 should be understood as the moving direction of the mounting block 5, that is, the first direction, so that when the mounting block 5 moves along the first direction, the guide column 331 can slide in the guide hole 332, so as to further ensure the reliability and stability of the moving process of the mounting block 5.
[0034] In some embodiments of the present disclosure, reference Figure 2 As shown, the guide hole 332 is arranged on the mounting block 5, wherein the central axis of the guide hole 332 is colinear with the central axis of the height adjustment hole 52, and the aperture of the guide hole 332 is smaller than the aperture of the height adjustment hole 52. In some embodiments of the present disclosure, the elastic member 31 can be sleeved on the outer periphery of the guide column 331, which can make the structure of the entire film pressing mechanism more compact on the one hand, and can avoid the elastic member 31 from bending or abnormal elastic deformation in the height adjustment hole 52 on the other hand. In addition, the elastic member 31 abuts against the bottom wall of the height adjustment hole 52, so that when the mounting block 5 moves downward, the elastic force of the elastic member 31 can be used to buffer the mounting block 5, so as to ensure the reliability and stability of the moving process of the mounting block 5. The guide column 331 is connected to the bottom of the base 1, and the guide hole 332 passes through the mounting block 5 along the first direction. When the mounting block 5 moves along the first direction, it can move along the extension direction of the guide column 331, so as to avoid the displacement of the mounting block 5 when it moves. The guide post 331 is detachably connected to the base 1 for easy disassembly, assembly and replacement.
[0035] In some embodiments of the present disclosure, reference Figure 1 and Figure 2 As shown, the first locking member 32 is configured as a screw with an external thread, and the second locking member is configured as a screw hole, which has an internal thread that matches the external thread. The end of the screw can be screwed in until it abuts against the mounting block 5, and the screw can be continuously rotated to push the mounting block 5 to move along the first direction to adjust the height of the mounting block 5 and the pressure roller 2, and when the screw is rotated to a preset position, the screw can be fixed by the threaded structure to limit its movement.
[0036] In some embodiments of the present disclosure, the locking structure may further include a nut, which is sleeved on one end of the screw away from the mounting block 5. When the screw is rotated to a preset position, the nut is screwed relative to the screw until it abuts against the second mounting block 7 to fix the position of the screw.
[0037] In some embodiments of the present disclosure, reference Figure 1 and Figure 2As shown, each mounting block 5 is provided with a strip hole 51, a first inclination adjustment hole and a second inclination adjustment hole, the strip hole 51 penetrates the corresponding mounting block 5 along the second direction and has a strip-shaped cross-section in the third direction, the first inclination adjustment hole and the second inclination adjustment hole both extend along the third direction to be connected with the strip hole 51, and the two ends of the pressure roller 2 are respectively detachably mounted in the strip holes 51 on the corresponding mounting block 5; the second adjustment component includes a first inclination adjustment member 41 and a second inclination adjustment member 42; one end of the first inclination adjustment member 41 is formed as an adjustment end, and the other end is inserted into the first inclination adjustment hole and abuts against the end of the pressure roller 2, and one end of the second inclination adjustment member 42 is formed as an adjustment end, and the other end is inserted into the second inclination adjustment hole and abuts against the end of the pressure roller 2, wherein the third direction intersects with the first direction and the second direction respectively.
[0038] The roller shaft 21 of the pressure roller 2 is respectively installed in the strip holes 51 of the mounting blocks 5 at both ends, and a locking member is provided at the end of the pressure roller 2, and the locking member can be screwed in to abut against the mounting block 5 to fix the position of the pressure roller 2. In this way, when the locking member is screwed in to abut against the mounting block 5, the pressure roller 2 can be in a fixed state, and when the locking member is away from the mounting block 5, so that the roller shaft 21 of the pressure roller 2 can slide in the strip hole 51 along the extension direction of the strip hole 51, the pressure roller 2 can be in an adjustment state. In the mounting blocks 5 at both ends of the pressure roller 2, the first inclination adjustment hole and the second inclination adjustment hole are respectively provided on both sides of the pressure roller 2 in the third direction. In this way, when the pressure roller 2 is in the adjustment state, the adjustment end of the first inclination adjustment member 41 is rotated so that the first inclination adjustment member 41 abuts against the roller shaft 21 of the pressure roller 2 from both ends, so as to apply opposite forces to the two ends of the roller shaft 21 of the pressure roller 2, so that the roller shaft 21 can rotate counterclockwise to a position that coincides with the second direction. When the adjusting end of the second inclination adjusting member 42 is rotated, the second inclination adjusting member 42 abuts against the end of the pressure roller 2 from both ends to apply forces in opposite directions to both ends of the roller shaft 21 of the pressure roller 2, so that the pressure roller 2 can rotate clockwise to a position that coincides with the second direction to adjust the inclination of the pressure roller 2 relative to the second direction, and the locking member adjusts the pressure roller 2 to a fixed state. By adjusting the first inclination adjusting member 41 or the second inclination adjusting member 42, the deviation of the pressure roller 2 in different directions relative to the second direction can be adjusted, so that the extension direction of the film can be perpendicular to the extension direction of the roller shaft 21 of the pressure roller 2, avoiding the film from wrinkling during the transmission process, and improving the lamination efficiency and lamination quality.
[0039] According to the second aspect of the present disclosure, Figures 3 to 5As shown, a packaging device is provided, which includes a feeding mechanism 10, a film pressing mechanism and a film supply mechanism 20. The feeding mechanism 10 includes a conveyor belt, which is used to convey products; the film pressing mechanism is installed on the feeding mechanism 10, and a gap is set between the pressing roller 2 of the film pressing mechanism and the product to be coated; the film supply mechanism 20 is located above the film pressing mechanism, and the film on the film supply mechanism 20 can be pulled to the gap between the pressing roller 2 and the product to be coated. The film on the film supply mechanism 20 is pulled to the gap between the pressing roller 2 and the product to be coated, and the film is pressed by the pressing roller 2 to realize the film coating process of the product to be coated on the feeding mechanism 10 in sequence.
[0040] In some embodiments of the present disclosure, reference Figure 4 and Figure 5 As shown, the packaging device also includes a loading mechanism 30, which includes a first loading component 301 and a second loading component 302. The driving component 303 can drive the first loading component 301 and the first loading component 302 to slide along the slide rail 304, so that one of the first loading component 301 and the first loading component 302 can correspond to the feeding mechanism 10 to realize alternating feeding of the feeding mechanism 10.
[0041] In some embodiments of the present disclosure, reference Figure 3 As shown, the packaging device further includes a second pressing roller 8, which is located upstream of the film pressing mechanism. In this way, before the film is pressed onto the surface of the product to be coated by the pressing roller 2, the film can be smoothed by the second pressing roller 8 and then pulled to the pressing roller 2 for pressing, thereby improving the reliability of the film coating.
[0042] Next, the present disclosure will introduce the specific steps of using the film pressing mechanism in detail in combination with the above specific implementation methods. Figures 1 to 5As shown, the roll film is installed on the film supply mechanism 20, and the film is smoothed by the second pressure roller 8 and then pulled to the pressure roller 2. When the product to be coated moves on the conveyor belt and passes through the pressure roller 2, the pressure roller 2 can press the film to fit the product to be coated. The coated product continues to move with the conveyor belt and pulls the film forward so as to continue to coat the product to be coated. When the pressure of the pressure roller 2 on the film cannot press the film to fit the product to be coated, the first locking members 32 at both ends of the pressure roller 2 are rotated to apply pressure to the mounting block 5 to make it move downward in the first direction, so that the pressure roller 2 can have enough pressure to press the film. When the height of the pressure roller 2 is too low and the pressure is too large, so that the product to be coated cannot pass through, the first locking member 32 is rotated to move upward, so that under the elastic force of the elastic member 31, the mounting block 5 moves upward, so that there is enough gap between the pressure roller 2 and the product to be coated to pass. If the pressure roller 2 deviates relative to the second direction, resulting in uneven film passing through, when the pressure roller 2 deviates counterclockwise relative to the second direction, the first inclination adjusting members 41 at both ends of the pressure roller 2 are rotated to abut against the roller shaft 21 of the pressure roller 2, and a force in a direction opposite to the roller shaft 21 is applied to make it rotate clockwise to be perpendicular to the extension direction of the film. When the pressure roller 2 deviates clockwise relative to the second direction, the second inclination adjusting members 42 at both ends of the pressure roller 2 are rotated to abut against the roller shaft 21 of the pressure roller 2, and a force in a direction opposite to the roller shaft 21 is applied to make it rotate counterclockwise to be perpendicular to the extension direction of the film, thereby ensuring the flatness of the film.
[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
