Description

Technical Field

[0001] This application relates to the field of labeling equipment technology, and in particular to a corner-folding labeling machine. Background Technology

[0002] A corner-folding labeling machine is a device that uses adhesives to affix labels, such as paper and metal foil, to specified packaging containers. It is an indispensable component of the modern packaging industry. With technological advancements and improved living standards, consumers' demands for packaging quality are increasing, and a large number of products require labeling for differentiation and better marketing. As labeling machines have developed, the current situation is gradually shifting from outdated manual and semi-automatic labeling methods to automated, high-speed systems.

[0003] In daily life, many packaging boxes have labels bent at 90° pasted on their openings. This serves two purposes: sealing the opening and indicating that the box has not been opened. In existing technology, labeling machines generally include a labeling device, a corner-folding device, and a conveyor belt. The labeling device and corner-folding device are located on one side of the conveyor belt, with the labeling device upstream and the corner-folding device downstream. The conveying sections, from upstream to downstream, include a first conveying section, an intermediate section, and a second conveying section. A clamping device for conveying the intermediate section is also included, located within the intermediate section.

[0004] Regarding the aforementioned technologies, current labeling machines lack corresponding positioning devices, resulting in significant deviations in labeling position during the labeling process on packaging boxes, thus requiring improvement. Utility Model Content

[0005] To facilitate the positioning of packaging boxes and improve the uniformity of labeling positions, this application provides a corner-folding labeling machine.

[0006] The corner-folding labeling machine provided in this application adopts the following technical solution:

[0007] A corner-folding labeling machine includes a base, a support platform, a labeling component, and a positioning component. The support platform is mounted on the base and is arranged horizontally. The labeling component is located on the plane of the support platform and is used to label packaging boxes. The positioning component is located on the support platform and is situated to one side of the labeling component. The positioning component is used to position the packaging box. The positioning component includes a guide plate and a locking member. The guide plate is fixed to the support platform by the locking member, and the packaging box moves along the guide plate towards the labeling component.

[0008] By adopting the above technical solution, when labeling is required, workers can place the packaging box on the support platform, then apply external force to the box, causing it to move linearly along the guide plate and approach the labeling component, thus completing the label application. The guide plate facilitates the positioning of the packaging box, improving the uniformity of labeling placement.

[0009] Preferably, the labeling assembly includes a fixing block, an abutment block, a connecting post, a return spring, and a support roller. The fixing block is disposed on the support platform. One end of the connecting post is connected to the abutment block, and the other end is movably disposed on the fixing block. The return spring is sleeved on the connecting post and located between the fixing block and the abutment block. The abutment block is used to contact the packaging box. The support roller is located below the abutment block and is disposed on the support platform. The support roller is tangent to the support surface of the support platform.

[0010] By adopting the above technical solution, the packaging box moves along the guide plate and gradually approaches the abutment block, at which point the label is located between the packaging box and the abutment block. When the packaging box presses onto the abutment block, part of the adhesive side of the label will stick to one side surface of the packaging box (the side surface of the packaging box facing the abutment block).

[0011] Next, the staff controls the packaging box to continue moving. Due to the presence of the connecting post, the abutment block moves along the direction closer to the fixed block, at which point the return spring is compressed. As the packaging box continues to move, the label paper, restrained by the support roller, adheres to the other surface of the packaging box (the surface where the packaging box and the support platform are in contact), thus completing the 90° bend and label application. After labeling, the packaging box is removed, and the abutment block automatically returns to its original position under the elastic restoring force of the return spring, allowing for labeling of the remaining packaging boxes.

[0012] Preferably, the guide plate includes a first plate and a second plate. The first plate is attached to the support platform and fixed by the locking member; the second plate is perpendicular to the first plate and is used to guide the packaging box.

[0013] By adopting the above technical solution, the locking component passes through the first plate and locks the first plate onto the support platform, thereby fixing the position of the guide plate.

[0014] Preferably, the first plate has a strip-shaped hole, which is arranged along the width direction of the support platform. One end of the locking member has a threaded portion. The locking member passes through the strip-shaped hole and is screwed onto the support platform. The distance between the second plate and the edge of the support platform is adjustable.

[0015] By adopting the above technical solution, the locking component is screwed onto the support platform, making the first plate and the support platform detachable. When it is necessary to guide packaging boxes of different widths, the locking component can be loosened first, and then the first plate can be controlled to move along the length direction of the strip hole. After adjustment, the locking component can be tightened to fix the position of the first plate.

[0016] Preferably, two parallel slots are provided, and the locking element is installed at both slots.

[0017] By adopting the above technical solution, the two locking parts together lock the first plate onto the support plate, and the first plate is fixed by using two points to form a line.

[0018] Preferably, the support platform is provided with scale lines, which are used to measure the distance between the second plate and the edge of the support platform.

[0019] By adopting the above technical solution, the presence of scale lines can help workers determine the distance between the second plate and the edge of the support platform, thereby better adjusting the position of the second plate relative to the support platform.

[0020] Preferably, it further includes a feeding shaft and a limiting baffle. The feeding shaft is disposed on the machine base and located below the support platform. The feeding shaft is used for the roll of label paper to pass through. The limiting baffle is disposed on the feeding shaft and is used to restrict the label paper from falling off the feeding shaft.

[0021] By adopting the above technical solution, the roll of label paper can be placed on the feeding shaft, and then the limiting baffle is engaged with the feeding shaft to limit the label paper and prevent it from falling off the feeding shaft.

[0022] Preferably, it also includes traction rollers, each of which is disposed on the machine base and is used to pull the label paper.

[0023] By adopting the above technical solution, the traction roller can pull the label paper, thereby improving the neatness of the label paper.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] (1) By setting up a positioning component, when labeling is required, the staff can place the packaging box on the support platform, and then apply external force to the packaging box, so that the packaging box moves in a straight line along the guide plate and approaches the labeling component, thereby completing the labeling. The guiding effect of the guide plate facilitates the positioning of the packaging box and improves the uniformity of the labeling position.

[0026] (2) By setting a strip hole in the first plate, when it is necessary to guide packaging boxes of different widths, the locking part can be loosened first, and then the first plate can be controlled to move along the length direction of the strip hole. After adjustment, the locking part is tightened to fix the position of the first plate, thereby changing the position of the second plate relative to the support platform.

[0027] (3) By setting scale lines, the existence of scale lines can help the staff to judge the distance between the second plate and the edge of the support platform, so as to better adjust the position of the second plate relative to the support platform. Attached Figure Description

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0036] This application discloses a corner-folding labeling machine. (Refer to...) Figure 1 and Figure 2 The corner-folding labeling machine includes a base 1, a support platform 2, a labeling assembly 3, and a positioning assembly 4. The base 1 serves as the carrier. The support platform 2 is rectangular and fixedly mounted on the base 1, positioned horizontally. The labeling assembly 3 is mounted on the plane of the support platform 2 and is used to label the packaging box. The positioning assembly 4 is mounted on the support platform 2 and located to one side of the labeling assembly 3. The positioning assembly 4 is used to position the packaging box. The positioning assembly 4 includes a guide plate 41 and a locking member 42. The guide plate 41 is fixed to the support platform 2 by the locking member 42, and the packaging box moves along the guide plate 41 towards the labeling assembly 3. The guide plate 41 includes an integrally connected first plate 411 and a second plate 412. The first plate 411 is attached to the support platform 2, and the locking member 42 passes through the first plate 411 and locks it to the support platform 2. The plane of the second plate 412 is perpendicular to the first plate 411, and the second plate 412 is used to guide the packaging box.

[0037] Specifically, the labeling assembly 3 includes a fixing block 31, an abutment block 32, a connecting post 33, a return spring 34, and a support roller 35. The fixing block 31 is fixedly connected to the support platform 2. One end of the connecting post 33 is connected to the abutment block 32, and the other end is movably mounted on the fixing block 31. The connecting post 33 moves linearly in the horizontal direction. The return spring 34 is sleeved on the connecting post 33 and is located between the fixing block 31 and the abutment block 32. The abutment block 32 is used to contact the packaging box. The support roller 35 is mounted on the support platform 2 and is located directly below the abutment block 32. The support roller 35 is tangent to the support surface of the support platform 2.

[0038] When labeling is required, the worker can place the packaging box on the support platform 2 and then apply external force to the packaging box, causing it to move along the guide plate 41 and gradually approach the abutment block 32. At this time, the label is located between the packaging box and the abutment block 32. When the packaging box is pressed on the abutment block 32, part of the adhesive side of the label will stick to one side surface of the packaging box (the side surface of the packaging box facing the abutment block 32).

[0039] Next, the staff controls the packaging box to continue moving. Due to the presence of the connecting post 33, the abutment block 32 will move along the packaging box towards the fixing block 31, at which point the return spring 34 will be compressed. As the packaging box continues to move, the label paper, restricted by the support roller 35, will adhere to the other side surface of the packaging box (the side surface where the packaging box and the support platform 2 are in contact), thus completing the 90° bend label application. After labeling, the packaging box is removed, and the abutment block 32 will automatically return to its original position under the elastic restoring force of the return spring 34, facilitating labeling of the remaining packaging boxes. The guide plate 41 facilitates the positioning of the packaging boxes, improving the uniformity of the labeling position.

[0040] In some embodiments, the first plate 411 has a strip-shaped hole 5, which is arranged along the width direction of the support platform 2, and the length direction of the strip-shaped hole 5 is perpendicular to the second plate 412. One end of the locking member 42 is provided with a threaded portion. The locking member 42 passes through the strip-shaped hole 5 and is screwed onto the support platform 2. The distance between the second plate 412 and the edge of the support platform 2 is adjustable. Since the locking member 42 is screwed onto the support platform 2, the first plate 411 and the support platform 2 are detachable. When it is necessary to guide packaging boxes of different widths, the locking member 42 can be loosened first, and then the first plate 411 can be moved along the length direction of the strip-shaped hole 5. After adjustment, the locking member 42 can be tightened to fix the position of the first plate 411.

[0041] As shown in the figure, two parallel strip-shaped holes 5 are provided, and locking elements 42 are installed at both holes 5. The two locking elements 42 together lock the first plate 411 onto the support plate, using the principle of two points forming a line to fix the first plate 411. The support platform 2 has a scale line 9, which is used to measure the distance between the second plate 412 and the edge of the support platform 2. The scale line 9 helps the operator determine the distance between the second plate 412 and the edge of the support platform 2, thereby better adjusting the position of the second plate 412 relative to the support platform 2.

[0042] In addition, a feeding shaft 6 and traction rollers 8 are installed on the base 1. One end of the feeding shaft 6 is fixedly connected to the base 1 and located below the table surface of the support platform 2. The feeding shaft 6 is used to feed the rolled label paper through. A limit baffle 7 is also installed on the feeding shaft 6. The limit baffle 7 is detachably connected to the feeding shaft 6 by a snap-fit ​​mechanism. The limit baffle 7 is used to prevent the label paper from falling off the feeding shaft 6. The traction rollers 8 are parallel to the feeding shaft 6 and are arranged in several rows. The traction rollers 8 are spaced apart on the base 1 and are used to pull the label paper to improve the neatness of the label paper.

[0043] The implementation principle of the corner-folding labeling machine in this application embodiment is as follows: When labeling is required, the worker can place the packaging box on the support platform 2, and then apply external force to the packaging box, causing the packaging box to move linearly along the guide plate 41 and approach the labeling component 3, thereby completing the labeling. The guiding effect of the guide plate 41 facilitates the positioning of the packaging box and improves the uniformity of the labeling position.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
