Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging equipment, specifically to a positioning fixture for a glue spraying module. Background Technology

[0002] In the tobacco packaging production industry, the carton packaging machine is a key piece of equipment used to seal cigarette cartons with a transparent film. The adhesive spraying module is one of the core components of this machine, used to precisely apply adhesive to the carton paper to ensure the packaging's airtightness and appearance quality.

[0003] However, in actual production, the glue spraying modules may need to be disassembled for cleaning, repair, or replacement due to prolonged use, glue hardening and clogging of the spray nozzles, or equipment maintenance requirements. When reinstalling the disassembled glue spraying modules, precise positioning adjustments must be made to ensure that all modules are positioned consistently on the mounting table, thereby guaranteeing uniform glue application and packaging quality.

[0004] Currently, the repositioning of the adhesive spraying module mainly relies on manual adjustment by maintenance personnel. This manual calibration method has the following problems: 1. Low efficiency: The adjustment process relies on experience, requires repeated testing, consumes a lot of time, and affects production efficiency.

[0005] Second, the accuracy is difficult to guarantee: manual operation is prone to errors, which can cause the glue spraying position to shift and the installation positions of different glue spraying modules to deviate, affecting the packaging quality.

[0006] Third, high maintenance costs: Frequent adjustments increase labor costs and may lead to glue waste or equipment wear due to improper calibration. Utility Model Content

[0007] The purpose of this invention is to overcome the problems of low efficiency, low accuracy, and high maintenance cost of existing glue spraying modules for repositioning. This invention provides a glue spraying module positioning fixture that enables rapid positioning and installation of the glue spraying module and ensures that the installation position of the glue spraying module on the mounting table remains consistent. It is convenient, fast, and has high positioning accuracy, ensuring production efficiency and quality while reducing maintenance costs.

[0008] To achieve the above objectives, this utility model provides a positioning fixture for a glue spraying module, comprising: The mounting platform has a first reference surface, a second reference surface, and a third reference surface that are perpendicular to each other. A strip groove is formed through the mounting platform, and the direction of the strip groove is perpendicular to the first reference surface. A first positioning element has a first positioning surface, a second positioning surface, and a third positioning surface. The first positioning surface is fitted with a first reference surface, the second positioning surface is fitted with a second reference surface, and the third positioning surface is fitted with a third reference surface. The second positioning component is fixedly connected to the first positioning component. The second positioning component has a fourth positioning surface, which is perpendicular to the first reference surface and the length extension direction of the strip groove.

[0009] In some embodiments, two side plates are fixedly provided on the fourth positioning surface, and the opposite side of the two side plates is a first guide surface, which is perpendicular to both the first reference surface and the fourth positioning surface. Preferably, the side plate and the second positioning member are integrally formed; Preferably, the parallelism between the first guide surfaces is no greater than 0.04 mm, the flatness of the first guide surface is no greater than 0.05 mm, the perpendicularity between the first guide surface and the first reference surface and the fourth positioning surface is no greater than 0.05 mm, and the surface roughness of the first guide surface is no greater than Ra3.2.

[0010] In some embodiments, a mounting hole is provided on the first guide surface, and a magnetic suction element is fixedly provided in the mounting hole.

[0011] In some embodiments, a top plate is fixedly provided on the side plate away from the first reference surface, and the side of the top plate facing the first reference surface is a second guide surface, which is parallel to the first reference surface and perpendicular to the fourth positioning surface; Preferably, the top plate and the side plate are integrally formed; Preferably, the flatness of the second guide surface is not greater than 0.05 mm, and the surface roughness of the second guide surface is not greater than Ra3.2.

[0012] In some embodiments, two or more strip grooves are provided.

[0013] In some embodiments, the first positioning member and the second positioning member are integrally formed.

[0014] In some embodiments, the second positioning member has a through hole perpendicular to the fourth positioning surface, and a scale member is provided on the side of the second positioning member opposite to the fourth positioning surface.

[0015] In some embodiments, the flatness of the first reference surface, the second reference surface, the third reference surface, the first positioning surface, the second positioning surface, the third positioning surface, and the fourth positioning surface is not greater than 0.05 mm.

[0016] In some embodiments, the perpendicularity between the first reference surface, the second reference surface, and the third reference surface is no greater than 0.05 mm; the perpendicularity between the first positioning surface, the second positioning surface, and the third positioning surface is no greater than 0.05 mm; and the perpendicularity between the fourth positioning surface and the first reference surface is no greater than 0.05 mm.

[0017] In some embodiments, the surface roughness of the first positioning surface, the second positioning surface, the third positioning surface, and the fourth positioning surface is not greater than Ra3.2.

[0018] The adhesive spraying module positioning fixture, which applies the above-mentioned technical solution of this utility model, has the following effects: After aligning the three positioning surfaces of the first positioning component with the three reference surfaces of the mounting platform, the mounting platform positions the first positioning component. Since the second positioning component is fixedly connected to the first positioning component, the position of the second positioning component is simultaneously determined once the position of the first positioning component is determined. Then, the adhesive spraying module is fed along the strip groove until it abuts against the fourth positioning surface on the second positioning component. At this point, the position of the adhesive spraying module is also determined. The adhesive spraying module can then be fixed to the mounting platform using bolts or other fasteners in conjunction with the strip groove, thus completing the positioning and installation of the adhesive spraying module. This positioning and installation is convenient, quick, and highly accurate.

[0019] After the first positioning component and the second positioning component are removed from the mounting platform, they are used for positioning and installing the glue spraying module on another mounting platform of the same specifications. This ensures that the installation position of the glue spraying module on the mounting platform remains consistent, thereby guaranteeing production efficiency and production quality.

[0023] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] This invention provides a positioning fixture for a glue spraying module, used to accurately position a glue spraying module 600 on a mounting platform 100. The fixture includes a mounting platform 100, a first positioning element 200, and a second positioning element 300, which are fixedly connected to the first positioning element 200. The first positioning element 200 is attached to the mounting platform 100, and the mounting platform 100 limits the first positioning element 200 to six degrees of freedom, achieving precise positioning. Since the first positioning element 200 and the second positioning element 300 are fixedly connected, the position of the second positioning element 300 is determined simultaneously with the position of the first positioning element 200. At this time, the second positioning element 300 can cooperate with the mounting platform 100 to determine the installation position of the glue spraying module 600 on the mounting platform 100. Compared to manual positioning, this positioning fixture offers a convenient, quick, and accurate positioning process, while not relying on human experience, reducing the investment cost of manual positioning.

[0025] After the glue spraying module 600 is positioned and installed on the mounting platform 100, the first positioning component 200 and the second positioning component 300 are removed from the mounting platform 100. Then, the first positioning component 200 and the second positioning component 300 are used for positioning and installing the glue spraying module 600 on another mounting platform 100 of the same specification, so as to ensure that the installation position of the glue spraying module 600 on different mounting platforms 100 is consistent, thereby ensuring the quality of glue spraying production.

[0026] Specifically, the mounting platform 100 has a first reference surface 101, a second reference surface 102, and a third reference surface 103 that are perpendicular to each other. The first positioning member 200 has a first positioning surface 201, a second positioning surface 202, and a third positioning surface 203. The first positioning surface 201 is in contact with the first reference surface 101, the second positioning surface 202 is in contact with the second reference surface 102, and the third positioning surface 203 is in contact with the third reference surface 103, thus limiting the six degrees of freedom of the first positioning member 200. A strip groove 104 is formed through the mounting platform 100. The direction of the strip groove 104 is perpendicular to the first reference surface 101. The second positioning member 300 has a fourth positioning surface 301, which is perpendicular to the first reference surface 101 and the length extension direction of the strip groove 104. During the installation of the adhesive spraying module 600, the module is attached to the first reference surface 101 and moved along the length of the strip groove 104 until it abuts against the fourth positioning surface 301. The first reference surface 101, the fourth positioning surface 301, and the strip groove 104 restrict the adhesive spraying module 600 to six degrees of freedom, thus positioning it on the mounting platform 100. After positioning, the module 600 is fixed to the mounting platform 100 using fasteners that engage with the strip groove 104. The strip groove 104 provides guidance for the movement direction of the module 600 during positioning and also serves as a mating structure for fixing the module 600.

[0027] The present invention provides the following embodiments for the positioning fixture of the glue spraying module.

[0028] Example 1: Combined with appendix Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, in this embodiment, the mounting platform 100 is in the shape of a cone. Its top horizontal surface is the first reference surface 101, and the two vertical sides of the cone are the second reference surface 102 and the third reference surface 103, respectively. The cone angle is 90 degrees to ensure that the second reference surface 102 and the third reference surface 103 are perpendicular to each other. The strip groove 104 is opened through the mounting platform 100 in the vertical direction.

[0029] In this embodiment, the first positioning member 200 is a spatial right-angled member, and its three inner surfaces are the first positioning surface 201, the second positioning surface 202, and the third positioning surface 203, respectively. The second positioning member 300 is plate-shaped. After the first positioning member 200 is attached to the cone corner of the mounting platform 100, the first positioning member 200 and the second positioning member 300 are positioned, and the plate-shaped positioning member is in a vertical state. The glue spraying module 600 is attached to the first reference surface 101, and the glue spraying module 600 is moved from right to left along the length of the strip groove 104 until the left end of the glue spraying module 600 abuts against the fourth positioning surface 301.

[0030] During movement, the glue spraying module 600 can be partially engaged in the strip groove 104 to improve stability. After positioning, the glue spraying module 600 is fixed with fasteners. Alternatively, fasteners can be pre-tightened onto the glue spraying module 600 and inserted into the strip groove 104. The strip groove 104 restricts the fasteners, ensuring that the glue spraying module 600 can move stably along the length of the strip groove 104. After positioning, tightening the fasteners will fix the glue spraying module 600.

[0031] Example 2: Combined with appendix Figure 4 Appendix Figure 5 and appendix Figure 6 As shown, in this embodiment, the mounting platform 100 is in the shape of a rectangular groove. The bottom surface of the groove is the first reference surface 101, the side surface of the groove is the second reference surface 102, the end surface of the groove is the third reference surface 103, and the strip groove 104 is vertically opened through the bottom surface of the groove.

[0032] In this embodiment, the first positioning member 200 is L-shaped, with the two inner surfaces of the L-shape being the first positioning surface 201 and the third positioning surface 203, and the outer surface of the L-shape being the second positioning surface 202. The second positioning member 300 is plate-shaped. The first positioning member 200 and the second positioning member 300 are combined to form a Z-shaped component. After the first positioning member 200 is attached to the end of the rectangular groove, the first positioning member 200 and the second positioning member 300 are positioned, and the plate-shaped positioning member is in a vertical state. The glue spraying module 600 is attached to the first reference surface 101, and the glue spraying module 600 is moved from right to left along the length of the strip groove 104 until the left end of the glue spraying module 600 abuts against the fourth positioning surface 301.

[0033] During movement, the rectangular groove-shaped mounting platform 100 guides the adhesive spraying module 600. By aligning the length direction of the strip groove 104 with the length direction of the rectangular groove, it is possible to ensure that the adhesive spraying module 600 moves stably along the length direction of the strip groove 104 without needing to partially insert the adhesive spraying module 600 into the strip groove 104 or pre-tighten it with fasteners.

[0034] Example 3: This embodiment is a further modification of Embodiment 2. Specifically, in conjunction with the attached... Figure 7 and attached Figure 8 As shown, two side plates 400 are fixedly mounted on the fourth positioning surface 301. The opposite side of the two side plates 400 forms the first guide surface 401, which is perpendicular to both the first reference surface 101 and the fourth positioning surface 301. The side plates 400 further guide the movement of the adhesive spraying module 600. After the adhesive spraying module 600 is positioned, it is fixed to the mounting platform 100 by fasteners engaging with the strip groove 104. (See attached diagram.) Figure 9 and attached Figure 10 As shown, the fasteners are 700 bolts and 800 nuts.

[0035] In a further configuration, a mounting hole 402 is provided on the first guide surface 401, and a magnetic suction component 403 is fixedly installed in the mounting hole 402. The outer shell of the adhesive spraying module 600 is generally made of ferromagnetic material. After the adhesive spraying module 600 is positioned, the magnetic suction component 403 acts to attract and fix the adhesive spraying module 600, thereby improving the stability of the adhesive spraying module 600 during the fixed installation process using fasteners.

[0036] In a further configuration, the side plate 400 and the second positioning component 300 are integrally formed to improve the structural strength of the side plate 400.

[0037] In a further configuration, a top plate 500 is fixedly mounted on the side plate 400 away from the first reference surface 101. The side of the top plate 500 facing the first reference surface 101 is a second guide surface 501, which is parallel to the first reference surface 101 and perpendicular to the fourth positioning surface 301. The top plate 500 further guides the movement of the glue spraying module 600 and restricts the movement of the glue spraying module 600 in the vertical direction, thereby improving the stability of the movement of the glue spraying module 600.

[0038] In a further design, the top plate 500 and the side plate 400 are integrally formed to improve the structural strength of the top plate 500.

[0039] In addition, in some other preferred embodiments, two or more strip grooves 104 are provided. Firstly, when the strip grooves 104 are needed for guiding the movement of the adhesive spraying module 600, two or more strip grooves 104 can further improve the movement stability of the adhesive spraying module 600. Secondly, when the strip grooves 104 are needed to fix the adhesive spraying module 600, two or more strip grooves 104 can provide multiple mounting points, improving the stability of the adhesive spraying module 600 after fixed installation. Thirdly, after the adhesive spraying module 600 is put into operation, two or more strip grooves 104 can provide good heat dissipation.

[0040] In some other preferred embodiments, the first positioning member 200 and the second positioning member 300 are integrally formed, thereby improving the structural strength of the first positioning member 200 and the second positioning member 300. Specifically, the first positioning member 200 and the second positioning member 300 are manufactured as a single unit using 3D printing technology.

[0041] In some other preferred embodiments, the second positioning member 300 has a through hole 302 perpendicular to the fourth positioning surface 301, and a scale member 303 is provided on the side of the second positioning member 300 opposite to the fourth positioning surface 301. After the glue spraying module 600 completes positioning, the through hole 302 exposes the nozzle in the glue spraying module 600, facilitating adjustment of the nozzle opening. The scale member 303 facilitates quantitative adjustment of the nozzle opening of the glue spraying module 600, allowing for adjustment of the glue spraying parameters while completing positioning, thereby improving production efficiency.

[0042] In some other preferred embodiments, the flatness of the first reference surface 101, the second reference surface 102, the third reference surface 103, the first positioning surface 201, the second positioning surface 202, the third positioning surface 203, and the fourth positioning surface 301 is not greater than 0.05 mm.

[0044] In some other preferred embodiments, the surface roughness of the first positioning surface 201, the second positioning surface 202, the third positioning surface 203, and the fourth positioning surface 301 is no greater than Ra3.2.
