Description

Technical Field

[0001] This utility model relates to the field of tobacco testing technology, specifically to an automatic loading and unloading device for initial tack strength samples 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 common testing method is to glue the packaging materials together with a certain amount of water-based adhesive, then separate the two, and test the stress during the separation process to obtain the initial tack strength, a performance parameter.

[0004] However, the above-mentioned testing process mainly relies on human operation.

[0005] When comparative analysis is required on test papers of different materials and water-based adhesives of different components, a large amount of test data is needed. Relying on manual operation at this time would become very troublesome. Therefore, adopting mechanized and automated methods to replace manual labor is an important research and development direction.

[0006] Among them, the loading and unloading control method of water-based adhesive initial tack test samples is an important part of automated operation, and how to realize this process is an urgent technical problem to be solved.

[0007] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic loading and unloading device for water-based adhesive initial tack test samples, which enables automatic loading and unloading of water-based adhesive initial tack test samples.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic loading and unloading device for initial tack strength test samples of water-based adhesive for tobacco, comprising a first hopper, a second hopper, a first rotating arm, a second rotating arm, a recycling arm, and a recycling box.

[0010] The first hopper is a bottom outlet type hopper, and the first hopper is used to store the samples placed in the upper position;

[0011] The distal end of the first rotating arm is provided with an upper suction cup with telescopic movement, which is used to grab the sample from the lower outlet of the first hopper and transfer the sample to the upper position through rotation.

[0012] The second hopper is an upper outlet type hopper, and the second hopper is used to store the samples in the lower position;

[0013] The distal end of the second rotating arm is equipped with a telescopic, downward-positioned suction cup, which is used to grab the sample from the upper outlet of the second hopper and transfer the sample to the lower position through a rotational motion.

[0014] The distal end of the recovery arm is provided with a lower-positioned recovery suction cup, which is located on the movement path of the upper-positioned suction cup and is used to receive the sample in the upper-positioned suction cup.

[0015] The upper opening of the recycling box covers the location of the recycling suction cup and part of the movement range of the lower suction cup, and is used to recycle the used sample.

[0016] Based on the above, it also includes a base and a support. The recycling box is disposed on the base, and the first and second hoppers are respectively placed at both ends of the base. The support is equipped with a power mechanism for driving the first and second rotating arms.

[0017] Based on the above, the first hopper is mounted on one end of the base via a vertical frame.

[0018] Based on the above, the second hopper is installed at the other end of the base via a lifting mechanism.

[0019] Based on the above, the bracket is provided with a double-layer motor mounting plate. The power mechanism of the first rotating arm is mounted on the motor mounting plate on one side of the bracket, and the power mechanism of the second rotating arm is mounted on the motor mounting plate on the other side of the bracket.

[0020] Based on the above, the power mechanism includes a motor and a reducer.

[0021] Based on the above, the recycling arm is an L-shaped cantilever.

[0022] Based on the above, limit switches are respectively provided on the bracket corresponding to the first rotating arm and the second rotating arm.

[0023] Based on the above, the extension and retraction movements of both the upper and lower suction cups are driven by cylinders.

[0024] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0025] In the initial tack test of water-based adhesives, two samples are usually mounted on two relatively movable carriers, one above the other. The purpose of this invention is to remove the samples from the hopper and mount them on two different carriers. Therefore, the first hopper, in conjunction with the first rotating arm, loads the sample into the upper carrier, and the second hopper, in conjunction with the second rotating arm, loads the sample into the lower carrier. After loading, the sample from the lower carrier is directly sent to the recycling box via the second rotating arm, while the sample from the upper carrier is sent to the recycling box by the first rotating arm in conjunction with the recycling arm, thus completing a fully automated loading and unloading process.

[0026] This device replaces the manual process of loading and unloading materials one by one, improving efficiency and freeing up manpower. Attached Figure Description

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0032] like Figures 1-3 As shown, an automatic loading and unloading device for initial tack strength samples of water-based adhesive for tobacco includes a first hopper 1, a second hopper 2, a first rotating arm 3, a second rotating arm 4, a recycling arm 5, and a recycling box 6.

[0033] The first hopper 1 is a bottom outlet type hopper. The first hopper 1 is used to store the samples in the top position. In this embodiment, the first hopper 1 stores the samples with the paper side down, which are stacked in the first hopper 1 and taken away one by one from the bottom outlet.

[0034] It should be noted that the sample in this embodiment refers to a small piece of board with cigarette paper material pasted on one side and a relatively hard material on the other side. A batch of these boards are prepared in advance and are specifically used for the initial tack test of water-based adhesives.

[0035] The testing device in this embodiment includes a horizontally movable planar stage 100, a dispensing mechanism 200, and a pressing head 300. The planar stage 100 has negative pressure holes, and the pressing head 300 has a negative pressure channel. The pressing head is in the upper position, and the planar stage 100 is in the lower position.

[0036] The first rotating arm 3 is provided with an upper suction cup 32 for telescopic movement at its far end. The telescopic movement is driven by a first cylinder 31 installed at the far end of the rotating arm. It is used to grab the sample from the lower outlet of the first hopper 1 and transfer the sample to the upper position, i.e., the lower pressure head 300, through rotation.

[0037] The second hopper 2 is a top-outlet type hopper. The second hopper 2 is used to store samples placed in the bottom position. In this embodiment, the samples with the paper side facing up stored in the second hopper 2 are stacked in the second hopper 2 and taken out one by one from the top outlet.

[0038] In a preferred embodiment, the second hopper is also equipped with a lifting mechanism 21. Each time a sample is taken away, the lifting mechanism drives the second hopper 2 to rise a short distance to ensure that the height of the top sample remains unchanged. The lifting mechanism can be a linear motor or an electric push rod.

[0039] The distal end of the second rotating arm 4 is provided with a lower suction cup 42 for telescopic movement. The telescopic movement is driven by a second cylinder 41 installed at the distal end of the second rotating arm 4. It is used to grab the sample from the upper outlet of the second hopper 4 and transfer the sample to the lower position through rotation.

[0040] The recovery arm 5 is an L-shaped cantilever. The far end of the recovery arm 5 is provided with a lower-positioned recovery suction cup 51. The recovery suction cup 51 is located on the movement path of the upper-positioned suction cup 32 and is used to receive the sample in the upper-positioned suction cup 32. The recovery suction cup 51 in the recovery arm plays the role of intermediate receiving.

[0041] The upper opening of the recycling box 6 covers the location of the recycling suction cup 51 and part of the movement range of the lower suction cup 42, and is used to recycle the used sample.

[0042] In this embodiment, all components of the entire device are mounted on the base 7 and the bracket 8. The recycling box 6 is set on the base 7. The first hopper 1 and the second hopper 2 are placed at both ends of the base 7. Specifically, the first hopper 1 is mounted on one end of the base by a stand; the second hopper 2 is mounted on the other end of the base by the lifting mechanism 21.

[0043] The bracket 8 is provided with a double-layer motor mounting plate. The power mechanism of the first rotating arm 3 is mounted on the motor mounting plate on one side of the bracket, and the power mechanism of the second rotating arm 4 is mounted on the motor mounting plate on the other side of the bracket. The power mechanism includes a motor and a reducer 9.

[0044] Limit switches are provided on the bracket 8 corresponding to the first rotating arm and the second rotating arm, respectively, to constrain the movement position of the first rotating arm and the second rotating arm.

[0045] Working principle explanation:

[0046] The first hopper 1 stores samples with the paper facing down, and the second hopper 2 stores samples with the paper facing up.

[0047] The first rotating arm 3, in conjunction with the upper suction cup 32, takes out the sample from the bottom of the first hopper 1, and then rotates to the lower pressure head 300 of the testing equipment, where the lower pressure head 300 adsorbs and fixes the sample.

[0048] The second rotating arm 4, in conjunction with the lower suction cup 42, takes out the sample from the top of the second hopper 4, and then rotates to the flat platform 100 of the testing equipment, where the flat platform 100 adsorbs and fixes the sample.

[0049] The dispensing mechanism 200 dispenses adhesive onto the sample on the flat stage 100. After dispensing, the flat stage 100 moves horizontally to below the pressing head 300. The pressing head 300 moves downward to stick the two samples together. During this process, data such as pressing speed, pressing distance, and initial pressure are recorded. After holding for a set time, the pressing head 300 moves upward and separates the two samples. The stress conditions are recorded during the process, and the maximum stress value is the initial adhesion force.

[0050] After the experiment, the first rotating arm 3 sucks the sample off the pressing head 300 and transfers it to the recovery suction cup 51 of the recovery arm 5. The recovery suction cup 51 releases the sample after the first rotating arm 3 moves away, and the sample is sent to the recovery box. Similarly, the second rotating arm 4 sucks the sample off the flat platform 100, transfers it above the recovery box 6 and releases the sample, which is then sent to the recovery box for centralized recycling.

[0051] During this process, the adhesive may have some residual tack. Usually, a waiting time can be set. Since it is a water-based adhesive, it dries easily, and this problem will be solved after it dries.

[0052] In colder or more humid environments, drying facilities can be added to accelerate the process. However, the requirements for experimental environments are usually consistent, and a uniform treatment method can be used, such as letting it stand for a period of time or air drying.

[0053] 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.
