Description

Technical Field

[0001] This application relates to the field of bottle labeling technology, and more specifically, to a preheating and tightening device for bottle labeling. Background Technology

[0002] The labeling device transports the bottles and cans to a position below the heat shrink film, cuts the heat shrink film, and inserts it onto the outside of the bottles and cans. The bottles and cans with the shrink film inserted are then transported to a drying oven for heating, so that the heat shrink film adheres smoothly to the bottles and cans.

[0003] Chinese Patent Publication No. CN208217186U discloses a beverage bottle labeling device. A secondary labeling device is set below the main labeling device. The secondary labeling device includes two horizontally parallel baffles, several horizontal cylinders connected to the outer ends of the baffles, and a vertical cylinder connected to the lower ends of the horizontal cylinders. The horizontal cylinders and the vertical cylinders are perpendicular to each other. During labeling, the position of the baffles is adjusted according to the diameter of the beverage bottle and the height of the label, thereby ensuring that the labeling height is consistent.

[0004] However, in actual use, the beverage bottle covered with heat shrink film is at a certain distance from the oven. During the process of transporting it to the oven, some of the heat shrink film inevitably slips off due to the vibration of the transmission device. This will undoubtedly affect the final forming quality of the label, resulting in product appearance defects and reducing product quality. Summary of the Invention

[0005] The purpose of this application is to provide a preheating and shrinking device for bottle labeling, which can solve the technical problem in the prior art where there is a certain distance between the beverage bottle after the heat shrink film is applied and the oven, and during the process of conveying it to the oven, some of the heat shrink film inevitably slips off due to the vibration of the transmission device, affecting the quality of the label forming.

[0006] This application provides a preheating and shrinking device for bottle labeling, including a mounting frame and a movable frame. The mounting frame is provided with a lifting and adjusting component for driving the movable frame to move up and down. The mounting frame and the movable frame are provided with clearance channels for heat shrink film to pass through. The movable frame is provided with a preheating mechanism for preheating and shrinking the heat shrink film and a positioning mechanism for positioning the heat shrink film from top to bottom.

[0007] Furthermore, the preheating mechanism includes two preheating components symmetrically arranged on the movable frame. Each preheating component includes a preheating cylinder, an arc-shaped mounting plate, and a heating plate. The preheating cylinder is horizontally fixed on the movable frame. The arc-shaped mounting plate is fixed on the telescopic rod of the preheating cylinder. The heating plate is fixed on the side of the arc-shaped mounting plate away from the preheating cylinder, and the heating plate is in contact with the inner arc surface of the arc-shaped mounting plate.

[0008] Furthermore, the positioning mechanism includes two positioning components symmetrically arranged on the movable frame. Each positioning component includes a positioning cylinder and a positioning plate. The positioning cylinder is horizontally fixed on the movable frame, and the positioning plate is fixed on the telescopic rod of the positioning cylinder.

[0009] Furthermore, a guide cylinder is vertically fixed on the mounting frame, the internal channel of the guide cylinder is the clearance channel, and the movable frame is movably mounted on the guide cylinder.

[0010] Furthermore, the lifting adjustment assembly includes a lifting motor, a screw, and a connecting block. The lifting motor is fixed on the mounting frame, and the connecting block is fixed on the movable frame. The upper end of the screw movably passes through the mounting frame and is connected to the output shaft of the lifting motor. The connecting block is provided with a threaded through hole adapted to the screw, and the screw is threadedly connected to the connecting block through the threaded through hole.

[0011] Furthermore, a rubber buffer block is fixed on the side of the positioning plate away from the positioning cylinder.

[0012] Furthermore, a fixing plate is fixed to the bottom of the mounting bracket, and the fixing plate has multiple fixing holes.

[0013] The beneficial effects of this utility model are:

[0014] This invention ensures the accuracy of the heat shrink film's position during the labeling process through a positioning mechanism, preventing the heat shrink film from shifting and ensuring the consistency of its position. The heat shrink film is preheated and compressed by a preheating mechanism, causing it to shrink initially before entering the oven, better adhering to the bottle surface and preventing it from slipping during transport to the oven. This ensures the final labeling quality and improves product quality. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Specific implementation examples:

[0027] like Figure 1 and Figure 2 As shown, this application provides a preheating and shrinking device for bottle labeling, including a mounting frame 1 and a movable frame 2. The mounting frame 1 is provided with a lifting and adjusting assembly 3 for driving the movable frame 2 to move up and down. The mounting frame 1 and the movable frame 2 are provided with a clearance channel 4 for the heat shrink film to pass through. The movable frame 2 is provided with a preheating mechanism 5 for preheating and shrinking the heat shrink film and a positioning mechanism 6 for positioning the heat shrink film from top to bottom. In use, the mounting frame 1 is fixed to the existing bottle conveying device, and the clearance channel 4 is positioned within the heat shrink film. Below the film, the lifting and adjusting component 3 adjusts the movable frame 2 to a suitable position. When the bottle is conveyed directly below the relief channel 4, the positioning mechanism 6 operates to position the heat shrink film that falls from the relief channel 4 onto the bottle, preventing the heat shrink film from shifting and ensuring the consistency of the heat shrink film's position. At this time, the preheating mechanism 5 is activated to preheat and shrink the heat shrink film, so that the heat shrink film initially shrinks before entering the oven, better adhering to the bottle surface, preventing it from slipping during the conveying process to the oven, ensuring the final label forming quality, and improving product quality.

[0028] like Figure 1 and Figure 2As shown, the preheating mechanism 5 includes two preheating components 51 symmetrically arranged on the movable frame 2. Each preheating component 51 includes a preheating cylinder 511, an arc-shaped mounting plate 512, and a heating plate 513. The preheating cylinder 511 is horizontally fixed on the movable frame 2. The arc-shaped mounting plate 512 is fixed on the telescopic rod of the preheating cylinder 511. The heating plate 513 is fixed on the side of the arc-shaped mounting plate 512 away from the preheating cylinder 511. The heating plate 513 is in contact with the inner arc surface of the arc-shaped mounting plate 512. Specifically, the heating plate 513 is externally powered. The preheating mechanism 5 is activated. During operation, the preheating cylinder 511 in each preheating component 51 pushes the arc-shaped mounting plate 512 to bring the heating plate 513 closer to the heat shrink film, heating the environment around the heat shrink film so that the heat shrink film reaches the shrinkage temperature and begins to shrink. The heating plate 513 fits into the inner arc surface of the arc-shaped mounting plate 512, which can better fit the curved surface of the heat shrink film, ensuring that the heat shrink film is heated evenly in the circumferential direction, thereby achieving a comprehensive and uniform preheating and shrinkage effect, reducing problems such as wrinkles and bubbles after labeling, and improving the quality and aesthetics of heat shrink film labeling.

[0029] like Figure 1 and Figure 2 As shown, the positioning mechanism 6 includes two positioning components 61 symmetrically arranged on the movable frame 2. Each positioning component 61 includes a positioning cylinder 611 and a positioning plate 612. The positioning cylinder 611 is horizontally fixed on the movable frame 2, and the positioning plate 612 is fixed on the telescopic rod of the positioning cylinder 611. When the positioning mechanism 6 is in operation, the positioning cylinder 611 on each positioning component 61 drives the positioning plate 612 to approach the bottle. After the heat shrink film falling from the clearance channel 4 is placed on the bottle, it contacts the top of the positioning plate 612. At this time, the positioning plate 612 plays the role of positioning the heat shrink film to ensure the consistency of the position of the heat shrink film on each bottle.

[0030] like Figure 1 and Figure 2 As shown, a guide cylinder 7 is vertically fixed on the mounting frame 1. The internal channel of the guide cylinder 7 is a clearance channel 4. The movable frame 2 is movably mounted on the guide cylinder 7. The guide cylinder 7 provides guidance for the movement of the movable frame 2, so that the movable frame 2 will not deviate or shake when it is driven to move up or down by the lifting and adjusting component 3.

[0031] like Figure 2As shown, the lifting adjustment assembly 3 includes a lifting motor 31, a screw 32, and a connecting block 33. The lifting motor 31 is fixed on the mounting frame 1, and the connecting block 33 is fixed on the movable frame 2. The upper end of the screw 32 movably passes through the mounting frame 1 and is connected to the output shaft of the lifting motor 31. The connecting block 33 is provided with a threaded through hole that matches the screw 32. The screw 32 is connected to the connecting thread through the threaded through hole. The lifting motor 31 drives the screw 32 to rotate, which in turn drives the connecting block 33 to move. The connecting block 33 then drives the movable frame 2 to move up and down along the guide cylinder 7, accurately controlling the lifting height of the movable frame 2. The movable frame 2 will then drive the positioning mechanism 6 to move, meeting the height requirements of different bottles for heat shrink film labeling.

[0032] like Figure 1 and Figure 2 As shown, a rubber buffer block 8 is fixed on the side of the positioning plate 612 away from the positioning cylinder 611. The rubber buffer block 8 can play a certain buffering role, avoid the bottle being over-compressed, and protect the bottle.

[0033] like Figure 1 and Figure 2 As shown, a fixing plate 9 is fixed to the bottom of the mounting bracket 1. The fixing plate 9 has multiple fixing holes 91. By using bolts to pass through the fixing holes 91 and the mounting holes on the transmission device frame, and with the help of nuts, the mounting plate can be fixed to the transmission device frame, thereby achieving the fixation of the entire device.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
