Description

Technical Field

[0001] The utility model relates to the technical field of sealing detection, in particular to a sealing detection device for the packaging of real stone paint coatings. Background Technique

[0002] Real stone paint is a special coating, usually used for indoor and outdoor wall decoration. Its name comes from its appearance and texture similar to that of natural stone surfaces. The construction of real stone paint usually includes multiple processes. By using special tools and techniques, various stone textures and effects can be created, such as marble, granite, sandstone, etc. Real stone paint has good weather resistance, durability and decorative properties, and is commonly used for the decoration and protection of the surfaces of building exteriors, interiors, floors, etc. After production, real stone paint needs to be sealed and packaged using paint packaging bags, and the packaging bags need to be subjected to sealing detection before use.

[0003] There are the following defects in an existing sealing detection device (authorized announcement number CN217901133U): The above device submerges the material to be detected into water through a clamping device, waits for the bubbles in the water to disappear, and then injects gas through a vent hole to observe whether bubbles are generated in the water for sealing detection. However, during detection, only a single detection object can be detected at a time, and it is difficult to observe when the detected material generates tiny bubbles, resulting in low detection efficiency, complex operation, and high detection difficulty of the device. Therefore, we propose the present utility model. Content of the Utility Model

[0004] The purpose of the present utility model is to solve the problems existing in the prior art, and to propose a sealing detection device for the packaging of real stone paint coatings.

[0005] In order to achieve the above purpose, the present utility model adopts the following technical scheme:

[0006] A sealing detection device for the packaging of real stone paint coatings, including an operation table, on the top surface of the operation table is fixedly installed a detection box, both sides of the detection box are open, inside the detection box is fixedly installed a detection structure, the detection structure includes two movable plates slidably arranged on the bottom surface inside the detection box, the two movable plates are symmetrically arranged, on the top surfaces of the two movable plates are fixedly installed partition boxes, inside the partition boxes are provided with a number of detection cavities, and on the bottom surface inside the detection cavities is attached white paper.

[0007] Preferably, on the top surface of the detection box is connected and fixedly installed an air extraction pipe, the bottom end of the air extraction pipe penetrates through the top surface of the operation table and is connected and fixedly installed with a vacuum pump, and both sides of the detection box are rotatably connected with installation doors through hinges.

[0008] Preferably, a bidirectional lead screw is arranged inside the detection box. One side of each of the two partition boxes is threadedly connected to the positive and negative threads of the bidirectional lead screw. Two support plates are fixed to the inner bottom surface of the detection box. One side of each of the two support plates is rotatably arranged with the bidirectional lead screw. A driving motor is fixed between the two support plates. Gears are fixed to the output end of the driving motor and the outer wall surface of the bidirectional lead screw respectively, and the two gears are meshed with each other.

[0009] Preferably, sealing grooves are formed on both open sides of the detection box. Rubber strips are slidably inserted into the sealing grooves, and the rubber strips are fixed to one side of the installation door.

[0010] Preferably, an observation hole is formed on one side of the installation door, and tempered glass is fixed inside the observation hole.

[0011] Preferably, a barometer is inserted into the top surface of the detection box.

[0012] The beneficial effects of the present utility model are as follows:

[0013] For this sealing detection device, through the setting of the detection structure, the staff injects colored liquid into multiple packaging bags to be detected and respectively places them into several detection cavities. Then, the installation door is closed, and the vacuum pump is started to gradually evacuate the air inside the detection box, so that the air pressure inside the detection box gradually decreases. When the air pressure inside the detection box decreases, the colored solution inside the packaging bag flows out from the crack of the packaging bag with poor sealing under the action of air pressure and falls onto the surface of the white paper. The colored solution inside the packaging bag with good sealing will not flow out. After the detection is completed, the staff can observe whether the white paper inside several detection cavities is stained, so as to judge the sealing quality of multiple packaging bags. The operation is convenient, the detection difficulty is reduced, and the detection efficiency is improved. Description of the Drawings

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to the attached Figure 1 - attached Figure 4 , a sealing detection device for the packaging of real stone paint coatings, including an operating platform 1, a detection box 2 is fixedly arranged on the top surface of the operating platform 1, both sides of the detection box 2 are open, a detection structure is fixedly arranged inside the detection box 2, the detection structure includes two movable plates 201 slidably arranged on the inner bottom surface of the detection box 2, the two movable plates 201 are symmetrically arranged, partition boxes 202 are fixedly arranged on the top surfaces of the two movable plates 201, a plurality of detection cavities 203 are opened inside the partition boxes 202, and white papers 204 are attached to the inner bottom surfaces of the detection cavities 203.

[0022] In the embodiment, an air extraction pipe 205 is fixedly communicated with the top surface of the detection box 2, the bottom end of the air extraction pipe 205 penetrates through the top surface of the operating platform 1 and is fixedly communicated with a vacuum pump 206. The vacuum pump 206 is a prior art. Installation doors 207 are rotatably connected to both sides of the detection box 2 through hinges. Through the setting of the detection structure, the staff injects colored liquids into a plurality of packaging bags to be detected and respectively places them into a plurality of detection cavities 203, closes the installation doors 207, starts the vacuum pump 206, gradually extracts the air inside the detection box 2, and gradually reduces the air pressure inside the detection box 2. When the air pressure inside the detection box 2 decreases, the colored solution inside the packaging bag flows out from the cracks of the packaging bag with poor sealing under the action of air pressure and falls onto the surface of the white paper 204. The colored solution inside the packaging bag with good sealing will not flow out. After the detection is completed, the staff can observe whether the white papers 204 inside the plurality of detection cavities 203 are stained, so as to judge the quality of the sealing of the plurality of packaging bags. The operation is convenient, the detection difficulty is reduced, and the detection efficiency is improved.

[0023] In an embodiment, a bidirectional lead screw 3 is disposed inside the detection box 2. One sides of the two partition boxes 202 are respectively threadedly connected to the positive and negative threads of the bidirectional lead screw 3. Two support plates 301 are fixed to the inner bottom surface of the detection box 2. One sides of the two support plates 301 are rotatably provided with the bidirectional lead screw 3. A driving motor is fixed between the two support plates 301. A gear 302 is fixed to the output end of the driving motor and the outer wall surface of the bidirectional lead screw 3. The two gears 302 are meshed with each other. When a staff member opens the detection box 2 and puts the packaging bag into the partition box 202, the staff member can start the driving motor to drive the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 causes the two partition boxes 202 and the two movable plates 201 to move away from each other, so that the partition box 202 is moved out of the detection box 2. After the packaging bag is placed, the driving motor is started to reverse, so that the partition box 202 and the movable plate 201 re-enter the detection box 2, thus facilitating the staff member to place the packaging bag.

[0024] In an embodiment, sealing grooves 4 are formed on both open sides of the detection box 2. A rubber strip 401 is slidably inserted into the sealing groove 4. The rubber strip 401 is fixed to one side of the installation door 207. When the installation door 207 is closed, the rubber strip 401 is inserted into the sealing groove 4. The friction between the rubber strip 401 and the sealing groove 4 makes the installation door 207 not easily opened, and at the same time ensures the sealing effect of the detection box 2.

[0025] In an embodiment, an observation hole 5 is formed on one side of the installation door 207. A tempered glass is fixed inside the observation hole 5. The staff member can observe the detection process of the packaging bag inside the detection box 2 through the observation hole 5.

[0026] In an embodiment, a barometer 6 is inserted into the top surface of the detection box 2. The staff member can detect the sealing performance of the packaging bag under different air pressures according to the barometer 6.

[0027] Working principle: During use, the staff inject colored liquid into multiple packaging bags to be detected and place them into several detection cavities 203 respectively. Then, close the installation door 207 and start the vacuum pump 206 to gradually evacuate the air in the detection box 2, causing the air pressure in the detection box 2 to gradually decrease. When the air pressure in the detection box 2 decreases, the colored solution in the packaging bag flows out from the cracks of the packaging bag with poor sealing and falls onto the surface of the white paper 204, while the colored solution in the packaging bag with good sealing will not flow out. After the detection is completed, the staff can observe whether the white paper 204 in the several detection cavities 203 is stained to determine the sealing quality of multiple packaging bags. When the staff opens the detection box 2 and places the packaging bag into the partition box 202, the staff can start the drive motor to drive the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 makes the two partition boxes 202 and the two movable plates 201 move away from each other, so that the partition box 202 is moved out of the detection box 2. After the packaging bag is placed, start the drive motor to reverse, so that the partition box 202 and the movable plate 201 re-enter the detection box 2, which is convenient for the staff to place the packaging bag. When the installation door 207 is closed, the rubber strip 401 is inserted into the sealing groove 4, and the friction between the rubber strip 401 and the sealing groove 4 makes the installation door 207 not easily opened, while ensuring the sealing effect of the detection box 2. The staff can observe the detection process of the packaging bag in the detection box 2 through the observation hole 5, and the staff can detect the sealing performance of the packaging bag under different air pressures according to the barometer 6.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
