Description

Technical Field

[0001] This utility model relates to the field of testing technology in the tobacco industry, specifically to a batch experimental device for determining the initial tack of water-based adhesives for tobacco. 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] Currently, the initial tack strength test of water-based adhesives for tobacco packaging materials mainly relies on manual testing. Simple tools are used to test each individual sample, which is relatively cumbersome and only suitable for application performance analysis of single samples.

[0004] When it is necessary to study the specific performance of water-based adhesives for tobacco, it is necessary to prepare a large number of comparative water-based adhesive samples by changing the interference caused by factors such as the composition, ratio, and process of the water-based adhesive, and then conduct comparative performance analysis to obtain the required data.

[0005] When performing such batch experiments, manual operation alone is difficult and costly. Therefore, it is necessary to develop a batch measurement experimental device that saves human resources to assist manual labor in completing batch experiments and reduce the workload of manual workers.

[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 batch testing device for determining the initial tack of water-based adhesives used in tobacco products. This device reduces labor intensity, assists manual labor in completing batch experiments, and improves experimental efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a batch testing device for initial tack strength of water-based adhesive for tobacco, comprising a linear track, multiple movable platforms, at least one dispensing mechanism, and a number of pressure head mechanisms equal to the number of movable platforms.

[0009] The plurality of movable platforms are all movably mounted on the linear track, and the upper surface of the movable platform is a plane;

[0010] The dispensing mechanism is located on one side of the linear track. The dispensing mechanism can move up and down. The dispensing mechanism is used to dispense glue onto the test sample placed on the upper surface of each moving platform.

[0011] Each of the aforementioned pressure head mechanisms is located on one side of a linear track. The pressure head mechanism can move up and down. The lower end of the pressure head mechanism is used to fix the upper test sample and to complete the bonding and separation of the upper test sample and the lower test sample after dispensing adhesive.

[0012] The pressure head mechanism integrates a tension / compression sensor to sense the force applied during the bonding and separation process between the upper test sample and the lower test sample after adhesive dispensing.

[0013] Based on the above, the dispensing mechanism and the pressure head mechanism are located on the same side of the linear track.

[0014] Based on the above, each of the pressure head mechanisms is located on the same side or different sides of the dispensing mechanism.

[0015] Based on the above, the mobile platform moves independently based on the linear track.

[0016] Based on the above, the mobile platform moves synchronously based on the linear track.

[0017] Based on the above, the pressure head mechanism also integrates a displacement sensor and a speed sensor, which are used to detect the displacement and travel speed of the pressure head mechanism, respectively.

[0018] Based on the above, the dispensing mechanism is an electric dispensing machine, and the glue cartridge component of the dispensing mechanism is mounted on the slider of the dispensing lifting mechanism.

[0019] Based on the above, the pressure head mechanism includes a pressure head lifting mechanism and a pressure head, the pressure head is mounted on the slider of the pressure head lifting mechanism, and the lower surface of the pressure head is a plane.

[0020] Based on the above, both the pressure head lifting mechanism and the dispensing lifting mechanism are electric lead screw assemblies or linear slides.

[0021] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0022] In the initial tack test, the process of pressing, bonding, and separating the two samples is the main time-consuming process. Therefore, this invention adds multiple moving platforms and multiple pressure head mechanisms to form multiple experimental stations. Since the dispensing mechanism needs to be compared with the same batch of water-based adhesives, a relatively small number of dispensing mechanisms are used to complete the dispensing process, which can ensure the consistency of the adhesive. Moreover, since the dispensing process is faster and fewer mechanisms are needed, it saves more resources. This configuration can greatly improve the experimental efficiency. The operator only needs to complete the work of installing the sample in place, removing the sample, and changing the adhesive, which greatly reduces the labor intensity. Attached Figure Description

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0029] like Figures 1-4 As shown, a batch testing device for initial tack strength of water-based adhesive for tobacco includes a linear track 100, multiple movable platforms 200, at least one dispensing mechanism 300, and a pressure head mechanism 400 equal in number to the movable platforms.

[0030] The multiple movable platforms 200 are all movably mounted on the linear track 100, and the upper surface of the movable platform 200 is a plane. In this embodiment, the movable platforms 200 can be platforms that move independently, or they can be movable platforms that can move synchronously driven by the same drive system. In the case of synchronous movement, the linear track 100 can be designed as a linear slide with multiple movable slides or an electric screw mechanism.

[0031] In this embodiment, the number of mobile platforms 200 is set to 3.

[0032] The dispensing mechanism 300 is located on one side of the linear track 100. The dispensing mechanism 300 is capable of lifting and lowering. The overall structure is an electric dispensing machine. The glue cylinder component 301 of the dispensing mechanism 300 is mounted on the slider of the dispensing lifting mechanism 302. The electric dispensing machine stores glue and is connected to the glue cylinder component 301 through a hose. The dispensing mechanism 300 is used to dispense glue onto the lower test samples placed on the upper surface of each movable platform 200.

[0033] Each of the aforementioned pressure head mechanisms 400 is disposed on one side of the linear track 100. In this embodiment, it is located on the same side as the dispensing mechanism 300. The pressure head mechanism 400 can move up and down, specifically including a pressure head lifting mechanism 401 and a pressure head 402. The pressure head 402 is mounted on the slider of the pressure head lifting mechanism 401. The lower surface of the pressure head is a plane. The lower end of the pressure head is used to fix the upper test sample and to complete the bonding and separation of the upper test sample and the lower test sample after dispensing.

[0034] The pressure head mechanism 400 integrates a tension / compression sensor 403, which is used to sense the force during the bonding and separation process of the upper test sample and the lower test sample after adhesive dispensing.

[0035] To facilitate the execution of the initial tack test after dispensing, each of the pressure head mechanisms is located on the same side of the dispensing mechanism. In other embodiments, they may be located on different sides of the dispensing mechanism.

[0036] To determine more operating parameters, the pressure head mechanism 400 also integrates a displacement sensor and a speed sensor, which are used to detect the displacement and travel speed of the pressure head mechanism, respectively, so as to understand the influence of these parameters on the initial adhesion determination, or to control the consistency of various parameters in each experiment.

[0037] Both the pressure head lifting mechanism 401 and the dispensing lifting mechanism 302 are electric lead screw assemblies or linear slides.

[0038] Working principle explanation:

[0039] First, a certain amount of test samples need to be prepared. The test samples are materials with a certain thickness formed by bonding double-sided tape and paper tobacco material. Then, they are cut into small pieces of the same size and shape. The surface of the paper tobacco material is the adhesive surface. The sample fixed on the movable platform 200 is called the lower test sample, and the sample fixed on the lower end face of the pressure head is called the upper test sample.

[0040] At the start of the test, the water-based adhesive to be tested is added to the dispensing machine. The lower test sample is fixed to each movable stage 200 using double-sided tape, and the upper test sample is fixed to each pressure head 402 using double-sided tape, so that their paper surfaces are facing each other.

[0041] Then, each moving platform 200 is driven to move and pass through the dispensing mechanism 300 one by one. The dispensing mechanism 300 dispenses glue onto the surface of each lower test sample it passes through.

[0042] After the dispensing process is completed, the moving platform is moved horizontally to the bottom of the corresponding pressure head mechanism. The pressure head mechanism 400 drives the upper test sample to move down and stick to the lower test sample. During this process, the downward movement distance, downward movement speed, initial contact pressure, holding pressure and holding time are controlled. After the holding time ends, the pressure head mechanism rises and resets. The force conditions of the whole process are recorded. The maximum tensile force value is called the initial tack force.

[0043] 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.
