TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sleeve label packaging, especially relates to a elastic bottle pressing mechanism, a conveying mechanism for conveying containers and sleeve label equipment. BACKGROUND

[0002] The sleeve label machine is widely applied in the fields of food, beverage, daily chemical industry and pharmacy etc. The sleeve label machine can automatically cut off the label belt and accurately sleeve, and cooperates with the subsequent heat shrinkage procedure, so as to fix the label on the cylindrical container. The sleeve label machine has excellent high-speed stability performance. Nowadays, the automatic high-speed sleeve label equipment has been widely applied in various fields.

[0003] For some packaging schemes which need to package the bottom, the container with the sleeved label needs to be lifted before being conveyed into the heat shrinkage furnace until after the heat shrinkage is completed, so that the label can be below the container bottom and thereby wrap the container bottom after heat shrinkage. During the lifting and conveying process, the container is prone to overturning or instability, so a corresponding auxiliary mechanism needs to be arranged above the container to ensure stable conveying of the container. However, the size of the container and the working tempo of each lifting mechanism are not necessarily completely consistent, and some containers may be slightly higher in position during the conveying process, while some containers may be slightly lower in position, or even just lifted, so the auxiliary mechanism needs to have a certain flexibility to compensate for the differences between different containers.

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will make further detailed description of the utility model in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0022] Figure 1 A preferred embodiment of the resilient bottle pressing mechanism is shown. Here, the entire resilient bottle pressing mechanism is designated by reference numeral 10 and comprises a base body 1, a strut 5 and a pressing plate 3. The base body 1 is designed as a cuboid made of plastic. On the upper surface of the base body 1, a recess 2 is configured, which is designed as an ellipse here. In the centre of each of the two ellipse halves, a through-hole is provided, which extends from the recess bottom to the underside of the base body 1 and through the entire base body 1. It is obvious that the recess can also be designed in another shape and that more than two through-holes can also be provided. However, it is advantageous to provide two through-holes, in each of which a strut 5 is arranged in an upwardly and downwardly movable manner, which allows a particularly stable construction. That is to say, the strut 5 passes through the through-hole and the outer diameter of the strut is smaller than the inner diameter of the through-hole. Here, one end of the strut 5 is rigidly connected to the pressing plate 3, for example by welding or riveting. The other end of the strut 5 has a flange, which projects out of the through-hole and can rest on the bottom of the recess 2. A spring 6 is arranged around the strut 5, one end of which rests on the pressing plate 3 and the other end of which rests on the lower surface of the base body 1. In the absence of external forces, the spring force of the spring 6 causes the flange of the strut to rest on the bottom of the recess 2. The pressing plate of the resilient bottle pressing mechanism can be displaced upwardly and downwardly in the event of spring deformation, so that a certain flexibility can be achieved by the resilient bottle pressing mechanism in order to adapt to containers of different sizes or different stages of jacking. On the side of the base body 1, fixing holes 4 are also provided, in particular two fixing holes above and below. By means of the fixing holes, the resilient bottle pressing mechanism 10 can be fixed to the conveying mechanism of the sleeve labelling device.

[0023] The pressing plate 3 is bent upwardly obliquely in the direction of the container. Thereby, a guiding effect is achieved during the container conveying, so that the entire container conveying is more smooth.

[0024] Figure 2 A schematic view of the conveyor belt mechanism arranged above is shown. By means of the conveyor belt mechanism, the containers are conveyed in the direction of the arrow 7. The resilient bottle pressing mechanism 10 is arranged on the conveyor belt mechanism. The resilient bottle pressing mechanism 10 is arranged on the conveyor belt mechanism in such a way that the pressing plate 3 is arranged above the conveyor belt 8. The pressing plate 3 is arranged in such a way that it is arranged above the container 9 during the conveying of the container 9. The resilient bottle pressing mechanism 10 is arranged in such a way that the pressing plate 3 is arranged above the container 9 during the conveying of the container 9. Figure 2It can be seen that the conveyor mechanism comprises a conveyor assembly 8 and a plurality of resilient bottle pressing mechanisms 10 arranged inside the conveyor assembly 8. The conveyor assembly 8 comprises, for example, a drive motor, a deflection roller and a conveyor belt. Fixed to the left and right sides of the conveyor assembly 8 are baffle plates 7. The resilient bottle pressing mechanisms 10 can be fixed to the baffle plates. Thus, the resilient bottle pressing mechanisms can be freely designed in the longitudinal direction and only the side surface is used for fixation. On the other hand, all the resilient bottle pressing mechanisms are fixed to the same baffle plate, which facilitates pre-assembly and replacement or removal. The pressing plate of the resilient bottle pressing mechanism 10 rests against a metal plate 9 fixedly arranged inside the conveyor mechanism, which is in sliding contact with the conveyor belt of the conveyor assembly 8 on the side facing the containers. The containers are clamped between the metal plate 9 and the lifting assembly. The metal plate itself is thin and thus has a certain deformation capacity. The deformation of the deformable metal plate in combination with the deformation of the resilient mechanism perfectly compensates for the differences caused by different container sizes and different container lifting stages.

[0025] Figure 3 is a structural schematic diagram of the conveyor mechanism in the embodiment of the utility model. Here, the conveyor mechanism comprises Figure 2 a conveyor belt mechanism arranged above and a conveyor chain mechanism arranged below as shown. The conveyor mechanism is generally used for conveying containers in a heat shrinkage oven. During the process of lifting the containers for bottom wrapping, the containers rest against the metal plate in the conveyor belt mechanism above, the bottom of the containers is lifted by the lifting rod of the lifting assembly, and thus the containers are clamped and held between the metal plate and the lifting rod. The conveyor chain mechanism comprises a conveyor chain 11 and a lifting assembly 12 arranged below the chain plate. The conveyor chain comprises a plurality of chain plates connected to each other. A hole is designed in the center of each chain plate or part of the chain plate. The lifting rod of the lifting assembly 12 can pass through the hole in the lifting state and lift the container.

[0026] Figure 4 is a schematic diagram of the lifting assembly 12 installed in the conveyor chain mechanism. The lifting assembly 12 comprises a U-shaped fixed frame 13, a lifting rod 16, a drive rod 15 and a return spring arranged around the lifting rod 16, which rests against the lifting rod flange facing the drive rod on one hand and rests against the lower side of the chain plate on the other hand. Thus, a simple lifting assembly is achieved. The U-shaped fixed frame 13 is fixed below the chain plate by means of two flanges 14 extending outward from the side wall. Here, for example, one through hole is respectively arranged on each flange 14, and a fixing screw or bolt can pass through the through hole and fix the lifting assembly 12 below the chain plate. A through hole is designed in the middle of the chain plate, and the lifting rod of the lifting assembly is arranged directly below the through hole. Thus, when needed, the lifting rod of the lifting assembly can pass through the through hole and move upward to lift the container. The drive rod 15 of the lifting assembly 12 can be directly or indirectly connected to the drive and drive the lifting rod 16 to move upward.
