Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle sealing detection, in particular to a plastic bottle sealing detection device. Background Technique

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles are widely made of polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials. After adding the corresponding organic solvents and being heated at high temperature, they are plastic containers formed by blow molding, extrusion blow molding, or injection molding through plastic molds. They are mainly used for disposable plastic packaging containers for liquids or solids such as beverages, foods, pickles, honey, dried fruits, edible oils, agricultural veterinary drugs, etc. Plastic bottles have the characteristics of being not easy to break, low cost, high transparency, and food-grade raw materials. When plastic bottles are produced, their sealing performance needs to be detected.

[0003] The applicant found through retrieval that the Chinese patent discloses "a plastic bottle sealing detection device", and its publication (announcement) number is "CN221224079U". This patent mainly replaces the traditional single-channel and single-station mode by setting a multi-conveyor channel and multi-station detection mechanism. In this way, the conveyor belt can convey plastic bottles at a normal speed, and at the same time, the detection work can be quickly completed through the multi-station detection mechanism without causing a stacking machine phenomenon, improving the detection efficiency. However, this patent can only detect the sealing performance of plastic bottles within a fixed diameter range, and the applicable range is relatively small. For this reason, we propose a plastic bottle sealing detection device. Content of the Utility Model

Specific implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model. Embodiment 1:

[0021] Please refer to the attached Figure 1 - attached Figure 4, A plastic bottle sealing detection device, including a base 1 and a clamping and pressing mechanism 4. The clamping and pressing mechanism 4 includes a forward and reverse motor 401, two groups of mounting frames 404, a limiting frame 411 and a water receiving frame 412. The forward and reverse motor 401 is connected with a synchronous toothed belt 403 through a driving tooth shaft 402. Sliders 405 are fixedly installed on both sides of the two groups of mounting frames 404. The two groups of mounting frames 404 are connected with clamping members 407 through insertion holes 406. Both ends of the two groups of mounting frames 404 are threadedly connected with bidirectional screw rods 409. Side frames 2 are fixedly installed on the upper surface of the base 1 near both sides. A sliding groove 3 is opened on the inner side surface of the side frame 2. The forward and reverse motor 401 is fixedly installed on the left side of the side frame 2. The driving tooth shaft 402 is fixedly installed on the output shaft of the forward and reverse motor 401. The slider 405 is slidably connected inside the sliding groove 3. The insertion hole 406 penetrates through the surface of the mounting frame 404. The clamping member 407 is inserted inside the insertion hole 406. A protective pad 408 is fixedly installed on the surface of the clamping member 407. The middle of the outer wall of the bidirectional screw rod 409 is rotatably connected inside the limiting frame 411. The bottom of the limiting frame 411 is fixedly installed on the upper surface of the base 1. One end of each of the two groups of bidirectional screw rods 409 is fixedly installed with a driven tooth shaft 410. The driving tooth shaft 402 and the driven tooth shaft 410 are both drivingly connected with the synchronous toothed belt 403. The bottom of the water receiving frame 412 is fixedly installed on the upper surface of the base 1.

[0022] The mounting frame 404 can be lengthened according to actual detection needs. As the mounting frame 404 is lengthened, the number of clamping members 407 can be increased, so that a large number of plastic bottles can be batch-tested for sealing at the same time. At the same time, the protective pad 408 on the clamping member 407 can protect the plastic bottles. The start and stop of the forward and reverse motor 401 can be controlled to adjust the pressure of the clamping member 407 on the plastic bottle.

[0023] Specifically, the rotation of the forward and reverse motor 401 can drive the driving tooth shaft 402 to rotate forward or reverse, so that the synchronous toothed belt 403 drives the two groups of mounting frames 404 on the bidirectional screw rod 409 to move relatively or away from each other through the driven tooth shaft 410, thereby realizing the clamping or loosening of the plastic bottle by the clamping member 407. The sealing performance of the plastic bottle is detected by observing the situation inside the water receiving frame 412. The movement of the mounting frame 404 on the bidirectional screw rod 409 can adapt to plastic bottles of different diameters, and multiple plastic bottles can be detected at one time, which is convenient and fast. Embodiment Two:

[0024] Please refer to the appendix Figure 1 and the appendix Figure 5, and on the basis of the first embodiment, it is further obtained that a blowing and watering mechanism 5 is arranged above the base 1. The blowing and watering mechanism 5 includes a mounting plate 501. A water pipe 503 and an air pipe 506 are fixedly mounted on the surface of the mounting plate 501. One end of the water pipe 503 is fixedly mounted with a water spray head 504, and one end of the air pipe 506 is fixedly mounted with an air jet head 507. The other end of the water pipe 503 is fixedly mounted with a water tank 502, and the water tank 502 is fixedly mounted on the left side surface of the side frame 2. The other end of the air pipe 506 is fixedly mounted with an air pump 505, and the air pump 505 is fixedly mounted on the right side surface of the side frame 2.

[0025] There is a water pump inside the water tank 502, which can spray water from the water tank 502 into the water pipe 503. There is a switch inside the water spray head 504, which can control the outflow of water. There is also a switch inside the air jet head 507, which can control the blowing of gas.

[0026] Specifically, the air pump 505 can spray gas from the air jet head 507 to clean the debris inside the plastic bottle, keep the inside clean, and avoid affecting the sealing performance detection. At the same time, the water pump in the water tank 502 can spray water from the water spray head 504 to fill the plastic bottle, which well cooperates with the clamping and pressing mechanism 4 to detect the sealing performance of the plastic bottle.

[0027] The working principle of this utility model: This utility model is a plastic bottle sealing performance detection device. First, take the plastic bottle to be detected to the air jet head 507, start the air pump 505, and blow and clean the debris inside the plastic bottle. Then, turn on the water pump of the water tank 502 so that water enters the plastic bottle from the water spray head 504 and fills the plastic bottle. Then, tighten the bottle cap, invert the plastic bottle inside the water receiving frame 412, and then control the forward and reverse motor 401 to rotate forward, so that the driving gear shaft 402 starts to rotate, drives the synchronous toothed belt 403 to rotate, and further makes the driven gear shaft 410 drive the bidirectional screw rod 409 to rotate. The two mounting frames 404 move relatively, so that the clamping members 407 clamp the plastic bottle. After clamping to a certain extent, turn off the forward and reverse motor 401 and wait for a period of time to observe whether there is water seepage inside the water receiving frame 412, so as to judge whether the sealing performance of the plastic bottle is intact.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
