DETAILED DESCRIPTION

[0036] The following description is intended to fully illustrate the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are intended to be exemplary only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0037] In order to avoid eddy current loss between cooling channels, which affects heat exchange efficiency, and facilitate glue pouring, the present invention provides the following embodiments.

[0038] See Figure 1-3 The present invention provides a self-adhesive labeling machine, comprising:

[0039] A conveying mechanism 100, wherein the conveying mechanism 100 is provided with a conveying track 101 defining a conveying direction, wherein a labeling station 102 is provided on the conveying track 101;

[0040] A positioning mechanism 200 is located above the conveying track 101. The positioning mechanism 200 includes a movable component 201 and a positioning component 202. The movable component 201 is configured to drive the positioning component 202 to move toward and away from the conveying track 101. The movable component 201 is configured to drive the positioning component 202 to move on both sides of the labeling station 102 along the conveying direction.

[0041] During use, the workpiece is first placed on the conveying track 101 of the conveying mechanism 100. The conveying mechanism 100 transfers the workpiece to be labeled along the conveying direction. Before the workpiece moves to the labeling station 102, the positioning mechanism 200 is started, and the movable component 201 on the positioning mechanism 200 drives the positioning component 202 to press the workpiece downward to position it. At the same time, the movable component 201 drives the positioning component 202 to act on the workpiece to move synchronously with the conveying direction and the conveying track 101. The workpiece is assisted in positioning by the positioning component 202 while being labeled by the labeling station 102, thereby avoiding the problem of displacement of the workpiece under the action of external forces such as label adhesion, resulting in poor label pasting effect.

[0042] In one embodiment of the present invention, the workpiece is a bottle body, which includes a bottle bottom, a bottle body, a bottle neck and a bottle mouth connected in sequence, and an arc-shaped transition between the bottle body and the bottle neck. The bottle body is rectangular. When labeling the bottle body, the bottle bottom is placed on the conveying track 101, wherein the bottle mouth faces upward, that is, the bottle mouth faces the positioning mechanism 200.

[0043] Furthermore, the positioning component 202 includes:

[0044] An upper pressing member 2021 connected to the movable assembly 201 , wherein the upper pressing member 2021 is provided with a bottle mouth accommodating area 20211 and a limiting opening 20212 communicating with the inside and outside of the bottle mouth accommodating area 20211 , wherein the limiting opening 20212 faces the conveying mechanism 100 ;

[0045] The upper pressing member 2021 extends outward to form the lower pressing member 2022, and the lower pressing member 2022 is arranged circumferentially along the limiting opening 20212. Preferably, there are multiple lower pressing members 2022, and the lower pressing members 2022 are arranged at intervals along the axial direction of the limiting opening 20212. In one embodiment of the present invention, there are four lower pressing members 2022, and the lower pressing members 2022 correspond to the corners of the bottle body one by one. When in use, the movable component 201 acts on the upper pressing member 2021 to limit the bottle body. Specifically, the opening on the upper pressing member 2021 is sleeved on the outside of the bottle mouth, and the bottle mouth enters the bottle mouth accommodating area 20211, and the lower pressing member 2022 limits the bottleneck and / or the bottle body.

[0046] Specifically, the upper pressing member 2021 is a cylindrical upper pressing member 2021, and the lower pressing member 2022 includes:

[0047] A bottleneck portion 20221 , wherein the upper pressing member 2021 extends toward a side away from the movable assembly 201 to form the bottleneck portion 20221 , and the bottleneck portion 20221 is arranged circumferentially along the limiting opening 20212 ;

[0048] The bottle body portion 20222, the radial outer side of the bottleneck portion 20221 extends downward to form the bottle body portion 20222, preferably, the connection between the bottleneck portion 20221 and the bottle body portion 20222 is an arc-shaped transition, so that the connection between the bottleneck portion 20221 and the bottle body portion 20222 can match and fit the connection between the bottle body and the bottleneck, preferably, the pressing member 2022 is a pressing member 2022 made of a non-rigid material, in one embodiment of the present invention, the outer surface of the pressing member 2022 is covered with a rubber layer to avoid damage to the bottle body and increase the friction with the bottle body, wherein the bottleneck portion 20221 and the bottleneck are in contact with each other, and the bottle body portion 2022 is located on the outside of the bottle body, thereby realizing simultaneous limitation of the bottle body and the bottleneck, and realizing sufficient limitation of the bottle body by the positioning component 202.

[0049] In order to further improve the positioning effect of the positioning assembly 202 on the bottle body, the positioning assembly 202 further includes:

[0050] The inner pressure piece 2023 is located in the bottle mouth accommodating area 20211. The inner pressure piece 2023 is an elastic inner pressure piece. The elastic direction of the inner pressure piece 2023 is the same as the axial direction of the upper pressure piece 2021. Specifically, the inner pressure piece 2023 is movably arranged along the axial direction of the upper pressure piece 2021. The inner pressure piece 2023 is provided with an elastic reset structure. More specifically, the side of the upper pressure piece 2021 away from the limiting opening 20212 is connected to the movable component 201, and the side of the upper pressure piece 2021 away from the limiting opening 20212 is provided with a sliding hole 20213 connected to the bottle mouth accommodating area 20211. The inner pressure piece 2023 is slidably installed in the sliding hole 20213. An elastic piece 2024 is provided between the inner pressure piece 2023 and the movable component 201, and the elastic piece 2024 can be a spring. During use, after the bottle mouth enters the bottle mouth accommodating area 20211, the internal pressure piece 2023 located in the bottle mouth accommodating area 20211 corresponds to the outside of the bottle mouth, so as to cooperate with the lower pressure piece 2022 to limit the inside and outside of the bottle body at the same time, thereby achieving the purpose of improving the limiting effect of the bottle body. The elastic internal pressure piece can produce a small displacement in the process of pressing the bottle mouth so that it can fully contact the bottle mouth, avoiding the problem that the bottle mouth cannot be stably fitted with the internal pressure piece 2023 due to production process or placement reasons.

[0051] Preferably, the internal pressure member 2023 includes a movable portion 20231 and a contact portion 20232 that are integrally connected, the movable portion 20231 is slidably installed in the sliding hole 20213, and the contact portion 20232 is located on the side of the movable portion 20231 facing the bottle mouth accommodating area 20211, and the cross-sectional size of the contact portion 20232 gradually decreases as it moves away from the movable portion 20231. In one embodiment of the present invention, the bottle mouth is a circular bottle mouth, and the contact portion 20232 is a conical contact portion 20232.

[0052] In one embodiment of the present invention, the movable component 201 includes a connecting plate 2013, a first screw 2014 and a second screw 2015, the connecting plate 2013 is provided with a first sub-screw hole 20131 and a second sub-screw hole 20132, the upper pressure piece 2021 is provided with a first female screw hole 20214, and the internal pressure piece 2023 is provided with a second female screw hole 20233, the first screw 2014 is screwed into the first sub-screw hole 20131 and the first female screw hole 20214 in sequence, the second screw 2015 is screwed into the second sub-screw hole 20132, the end of the second screw 2015 is slidingly connected to the second female screw hole 20233, one end of the elastic piece 2024 in the elastic direction abuts against the inner wall of the second female screw hole 20233, and the other end of the elastic piece 2024 in the elastic direction abuts against the connecting plate 2013. The first screw 2014 and the second screw 2015 are both arranged around the axis of the upper pressure member 2021 , with four first screws 2014 and two second screws 2015 . In another embodiment of the present invention, the elastic member 2024 may be installed between the upper pressure member 2021 and the inner pressure member 2023 .

[0053] Regarding the specific structure of the movable component 201, the movable component 201 includes:

[0054] Horizontal movable parts 2011;

[0055] The longitudinal movable member 2012 is installed on the transverse movable member 2011 , and the positioning assembly 202 is connected to a side of the longitudinal movable member 2012 away from the transverse movable member 2011 .

[0056] In one embodiment of the present invention, the transverse movable member 2011 is an electrically driven or pneumatically driven guide rail, and the longitudinal movable member 2012 is a telescopic cylinder. A connecting plate 2013 is laterally mounted on the movable end of the telescopic cylinder.

[0057] In order to improve the labeling effect on the bottle body and avoid deformation of the bottle body caused by the force generated by the labeling workpiece when the bottle body passes through the labeling station 102 due to the relatively soft bottle body material, the self-adhesive labeling machine further includes:

[0058] The positioning assembly 202 includes an inflation mechanism, a limited opening 20212 that seals against the bottle neck / bottle body, an inflation channel disposed within the positioning assembly 202, one end of the inflation channel communicating with the inflation mechanism, and an inflation port 2025 disposed on the positioning assembly 202 that communicates with the bottle mouth accommodating area 20211, wherein the inflation port 2025 communicates with the other end of the inflation channel. During use, the positioning assembly 202 is moved by the movable assembly 201, the bottle mouth accommodating area 20211 being sleeved onto the outer side of the bottle mouth, the limited opening 20212 sealingly engaging the bottle neck / bottle body, and the inflation mechanism injects gas into the bottle body through the inflation channel, the inflation port 2025, the bottle mouth accommodating area 20211, and the bottle mouth. The gas expands and tightens the bottle body, even though its surface has a certain hardness, ensuring a smooth contact surface with the film, thereby preventing deformation during the labeling process. In one embodiment of the present invention, the inflation mechanism is an air pump, wherein the inflation mechanism is an existing mature technology and is well known to those skilled in the art, and will not be described in detail here.

[0059] Preferably, the internal pressure member 2023 controls the connection of the inflation mechanism. Specifically, a trigger switch is provided at the bottom of the sliding hole 20213. When the internal pressure member 2023 contacts and abuts the inner wall of the bottle mouth, the internal pressure member 2023 contacts the trigger switch, and the trigger switch controls the connection of the inflation mechanism to start, thereby achieving downward positioning and inflation of the bottle body at the same time.

[0060] Furthermore, in order to position the bottles during the labeling process and detect the sealing of the bottles so as to remove bottles with unqualified sealing, the self-adhesive labeling machine also includes:

[0061] An air leakage detection mechanism connected to the inflation mechanism to detect the inflation pressure of the inflation mechanism and determine whether the bottle is leaking;

[0062] The screening mechanism is arranged at the rear side of the labeling station 102 in the conveying direction. The air leakage detection mechanism is controlled and connected to the screening mechanism. The screening mechanism can be used to remove leaking bottles from the conveying mechanism 100.

[0063] In one embodiment, the air leakage detection mechanism includes a controller and a pressure sensor. The pressure sensor monitors the pressure on the inflation mechanism. When the bottle injected by the inflation mechanism leaks, the pressure sensor transmits the monitoring signal to the controller, and the controller controls the screening mechanism. The screening mechanism can be a telescopic cylinder or a blowing structure. After the screening structure is started, it can push or blow unqualified workpieces to fall from the conveying mechanism 100.

[0064] In summary, the self-adhesive labeling machine presses down and positions the workpiece by means of the positioning assembly 202, wherein the positioning assembly 202 can move along the conveying direction of the workpiece while pressing down the workpiece, thereby enabling the labeling station 102 to label the workpiece, thereby avoiding the problem of the workpiece being displaced by external forces such as the adhesive force of the label, resulting in poor labeling effect;

[0065] A positioning assembly 202 is provided to press down and position the inside and outside of the bottle body, further ensuring that the bottle body is stable and does not shake during labeling. An inflation mechanism is provided to inject air into the bottle body, so that the bottle body can be labeled in a collision state, thereby improving the labeling effect.

[0066] A mechanism with a sealing effect detection function is provided so that when a leaking bottle is found, the leaking bottle can be removed from the conveying mechanism 100. This function is simultaneously realized when the bottle is pressed down to position it, thereby improving product quality and production efficiency.
