Description

Technical Field

[0001] This utility model relates to the field of testing technology in the tobacco industry, specifically to a device for measuring the initial tack of water-based adhesive for tobacco products with easily replaceable tubing. Background Technology

[0002] The adhesion ability of water-based adhesives for tobacco to packaging materials is divided into initial tack and holding power. Initial tack is an important indicator for measuring the adhesion between two surfaces and has a significant impact on the machine adaptability of water-based adhesives for tobacco.

[0003] In the initial tack test of water-based adhesives, one of the most important functions is to find the most suitable type of water-based adhesive for use in cigarette packaging materials. At present, although the water-based adhesive products provided by manufacturers can all be used, there is a fuzzy area regarding the relationship between water-based adhesives and packaging materials. Therefore, the industry is not clear about the corresponding relationship between the best matching schemes of water-based adhesives and packaging paper.

[0004] To solve this problem, it is necessary to design water-based adhesives with various components and ratios for packaging materials and conduct comparative experiments to study their correlation.

[0005] Traditional water-based adhesive experiments are mostly conducted by humans throughout the entire process. However, such comparative tests require a large number of test samples, resulting in a heavy workload. Manual operation cannot guarantee stability and efficiency. Therefore, it is necessary to develop a water-based adhesive initial tack measuring device that allows for easy replacement of the adhesive tube.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for measuring the initial tack of water-based adhesives for tobacco products that offers automated and easily replaceable hoses.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a device for measuring the initial tack of water-based adhesive for tobacco with easily replaceable hoses, comprising a hose hopper, a hose transfer mechanism, a moving platform, a dispensing mechanism, and a pressure head mechanism;

[0009] The hose hopper includes a rotary mechanism, several hose slots located at the moving end of the rotary mechanism, and a closed box. The distance between the top surface of the closed box and the ground is equal to the height of the hose. The top surface of the closed box is used to movably seal the top opening of the hose, and the bottom surface of the closed box is used to movably seal the drip nozzle of the hose. The circumferential surface of the closed box is provided with a hose storage inlet and a hose dispensing outlet.

[0010] The hose transfer mechanism is used to take out the hose from the hose outlet of the hose hopper and transfer the hose to the dispensing mechanism;

[0011] The dispensing mechanism includes a tube clamping assembly, a lifting assembly, and a pneumatic dispensing assembly. The tube clamping assembly is used to clamp the tube. The bottom end of the pneumatic dispensing assembly is provided with an air passage opening. The lifting assembly is used to drive the air passage opening at the bottom end of the pneumatic dispensing assembly to act on the opening at the top end of the tube to form a dispensing path.

[0012] The movable platform is used to switch positions between the dispensing station below the dispensing mechanism and the testing station below the pressure head mechanism;

[0013] The pressure head mechanism is used in conjunction with the moving platform to conduct experiments on the initial tack of water-based adhesives.

[0014] Based on the above, the enclosed housing of the hose hopper includes a top plate, a bottom plate, and an outer perimeter baffle. The projected shape of the enclosed housing is racetrack-shaped, and the rotary mechanism has a corresponding shape.

[0015] Based on the above, the tubing inlet is a notch with openings at the top and sides.

[0016] Based on the above, the outlet of the hose is a side-opening notch.

[0017] Based on the above, the moving end of the rotary mechanism is a double-layered flexible tape, and the flexible tape is provided with a tube clamping position.

[0018] Based on the above, the tubing is a syringe cavity structure tubing, the top opening of the tubing is flat, and the dispensing nozzle of the tubing is flat.

[0019] Based on the above, the hose transfer mechanism includes a translation mechanism, a rotating arm, and a horizontal chuck. The rotating arm is installed at the moving end of the translation mechanism, and the horizontal chuck is installed at the free end of the rotating arm.

[0020] Based on the above, the clamping surface of the hose clamping assembly is an arc surface that fits the hose.

[0021] Based on the above, a waste box is provided on one side of the mobile platform, and a scraper is provided on the waste box.

[0022] Based on the above, the pressure head mechanism integrates a tension / compression sensor.

[0023] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0024] The tubing used in this invention is a tubing without a top sealing film and a bottom plug. The top and bottom are sealed by sliding contact between the top surface of the sealed box in the tubing hopper and the ground, which is a dynamic sealing method. Since the tubing structure is in the form of a syringe and the bottom drip nozzle is small, the glue has a certain adhesion. Therefore, the dynamic sealing method is not likely to cause glue leakage.

[0025] Based on this, a corresponding tube transfer mechanism is set up to work with the dispensing mechanism, using pneumatic force to deliver the dispensing material outward, simulating the working mode of a dispensing machine, resulting in better controllability of dispensing accuracy.

[0026] Since there is no need to tear the film or remove the plug after the tubing is removed, its ease of use is greatly improved. Attached Figure Description

[0033] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0034] like Figures 1-5 As shown, a device for measuring the initial tack of water-based adhesive for tobacco with easily replaceable hoses includes a hose hopper 100, a hose transfer mechanism 200, a movable platform 300, a dispensing mechanism 400, and a pressure head mechanism 500.

[0035] The hose hopper 100 includes a rotary mechanism 101, a plurality of hose slots 102 disposed at the moving end of the rotary mechanism, and a closed box 103. The distance between the top surface and the ground of the closed box 103 is equal to the height of the hose 600. The top surface of the closed box 103 is used to movably seal the top opening of the hose 600, and the bottom surface of the closed box 103 is used to movably seal the drip nozzle of the hose 600. The circumferential surface of the closed box 103 is provided with a hose storage inlet 104 and a hose outlet 105.

[0036] In this embodiment, the tubing 600 used is a tubing with a syringe cavity structure. The top opening of the tubing 600 is flat, and the dispensing nozzle of the tubing is flat. The diameter of the dispensing nozzle is much smaller than the diameter of the cavity portion.

[0037] The enclosed housing of the hose hopper 100 includes a top plate, a bottom plate, and an outer perimeter baffle. The projected shape of the enclosed housing is racetrack-shaped, and the rotating mechanism is a corresponding racetrack-shaped shape. The hose storage inlet 104 has a notch with openings at the top and sides, and the hose outlet 105 has a notch with openings at the sides.

[0038] When inserting the tubing, insert it from the top into the tubing slot 102. When removing the tubing, remove it horizontally from the tubing slot 600.

[0039] To ensure clamping stability, the moving end of the rotary mechanism is a double-layered flexible tape, and the flexible tape is provided with a tube clamping position 102. The rotary mechanism can be a traditional rotary motor and rotary belt.

[0040] The hose transfer mechanism 200 is used to take out the hose 600 from the hose outlet 105 of the hose hopper 100 and transfer the hose 600 to the dispensing mechanism 400. In this embodiment, the hose transfer mechanism 200 includes a translation mechanism 201, a rotating arm 202 and a horizontal jaw 203. The rotating arm 202 is installed at the moving end of the translation mechanism 201, and the horizontal jaw 203 is installed at the free end of the rotating arm 202. The translation mechanism 201 can be an electric lead screw, the rotating arm 202 can be a servo motor, and the two jaws of the horizontal jaw 203 move horizontally relative to each other.

[0041] The dispensing mechanism 400 includes a tube clamping assembly 401, a lifting assembly 402, and a pneumatic dispensing assembly 403. The tube clamping assembly 401 is used to clamp the tube 600. The bottom end of the pneumatic dispensing assembly 403 is provided with an air passage opening. The lifting assembly 402 is used to drive the air passage opening at the bottom end of the pneumatic dispensing assembly 403 to act on the opening at the top end of the tube 600 to form a dispensing path. The dispensing action is controlled by pneumatic control, and the amount of dispensing in a single operation can be controlled within a precise range. The clamping surface of the tube clamping assembly 401 is an arc surface that fits the tube to ensure clamping stability.

[0042] The movable platform 300 is used to switch positions between the dispensing station below the dispensing mechanism 400 and the testing station below the pressure head mechanism 500; a waste box 301 is provided on one side of the movable platform 300, and a scraper 302 is provided on the waste box 301. The movable platform 300 includes a translation mechanism and a platform. The translation mechanism can be a linear motor or an electric screw mechanism, and the platform is a platform with a flat surface.

[0043] The pressure head mechanism 500 is used in conjunction with the moving platform to conduct the initial tack test of the water-based adhesive. The pressure head mechanism 500 integrates a tensile and compressive force sensor to collect pressure and tensile force during the separation process.

[0044] Working principle explanation:

[0045] The principle of initial tack test is to apply adhesive to the surface of the packaging material, then adhere the packaging material tightly, set a time, separate the packaging material, and read the tensile force required for separation. The maximum tensile force is expressed as the initial tack.

[0046] Based on the above principles, the specific working process of this embodiment includes:

[0047] The rotary mechanism 101 inside the hose hopper 100 rotates, transferring the hose to be tested 600 to the hose outlet 105. The hose transfer mechanism 200 horizontally moves to grab the hose 600, and after taking out the hose 600, it rotates 180° to send the hose 600 to the hose clamping assembly 401 of the dispensing mechanism 400. After clamping the hose, the hose transfer mechanism 200 returns to its original position.

[0048] The moving platform moves, aligning the waste box 301 with the dispensing mechanism 400. The pneumatic dispensing component 403 of the dispensing mechanism 400 is pressed down, causing the lower air port to act on the upper opening of the glue tube 600. The air valve opens, squeezing a section of glue from the front end of the glue tube into the waste box 301. After a set time, the platform stops, and the moving platform moves, controlling the scraper 302 to scrape the lower dispensing port of the glue tube 600 to remove the glue.

[0049] The moving platform continues to move so that the platform surface is directly opposite the dispensing nozzle of the glue tube. The test sample is fixed on the platform surface, and another sample is fixed on the lower surface of the pressure head mechanism 500. The dispensing mechanism 400 is controlled to work and a drop of water-based glue is dispensed onto the sample surface.

[0050] The moving platform continues to move, so that the platform surface moves below the pressure head mechanism 500. The pressure head mechanism 500 moves down and glues one side of the paper of the two samples together. After a set time, the pressure head mechanism 500 moves up and separates the two samples. During the process, the force is continuously read, and the maximum tensile force is the initial adhesion force.

[0051] The platform and pressure head mechanism can be fixed to the sample by double-sided tape or by negative pressure suction. The sample loading process can be done manually or by a robotic arm. Since this process is relatively simple and not the focus, it will not be described in detail.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
