Description

Technical Field

[0001] This utility model relates to the field of bottle manufacturing technology, and in particular, to a bottle airtightness testing device. Background Technology

[0002] Bottle airtightness testing is a core step in ensuring product safety and quality. Its necessity lies in: verifying sealing performance to prevent safety accidents caused by the leakage of toxic and flammable substances, ensuring that the contents of food, medicine and other products are not contaminated or deteriorated; at the same time, it meets the mandatory compliance requirements of industry regulations for pressure vessels, medical equipment and other fields, reduces the negative impact of gas leaks on the environment, and ultimately maintains brand reputation and consumer trust.

[0003] The airtightness of the bottle is usually tested using a separate airtightness testing device. This device typically includes a pressure cylinder with an airtight plug on its drive end. During testing, the bottle is placed under the pressure cylinder, and the airtight plug is then pressed against the bottle opening. The airtightness is determined by monitoring the pressure changes within the bottle.

[0004] However, this separate inspection method can easily lead to a decrease in bottle production efficiency because it involves the transfer of bottles between processes, which results in a waste of extra time. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bottle airtightness detection device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A bottle airtightness testing device is characterized by comprising a frame attached to the side of a bottle conveyor line, a testing mechanism being provided on the frame, a transport line being provided below the testing mechanism, and a guiding mechanism being provided between the bottle conveyor line and the transport line, the guiding mechanism being adapted to form a guiding channel that allows the bottle to flow between the bottle conveyor line and the transport line along the transport direction.

[0008] Preferably, the transport line includes a conveyor belt.

[0009] Preferably, the guiding mechanism includes two guide plates arranged in parallel and spaced apart, with the guide plate defining the guiding channel between the two guide plates.

[0010] Preferably, the guide plate is made of an elastic material, and the bottle conveying line is provided with support mechanisms at both ends of the conveying line, and the conveying line is also provided with support mechanisms, with the guide plate disposed on the support mechanisms.

[0011] Preferably, the support mechanism includes two symmetrically arranged bases, and a support plate is provided on the side wall of the base.

[0012] Preferably, the base has a connecting hole on its side wall, the support plate has a connecting rod on its side wall opposite to the guide plate, the connecting rod is inserted into the connecting hole, and the base is also provided with a locking member for locking the connecting rod.

[0013] Preferably, the locking element includes a tightening bolt threaded to the base, and the threaded hole of the tightening bolt communicates with the connecting hole.

[0014] Preferably, a bottle-pushing mechanism is also provided between the bottle conveying line and the transport line, and the bottle-pushing mechanism is adapted to push the bottle to flow in the guide channel.

[0015] Preferably, the bottle-dispensing mechanism includes a rotatable dispensing disc, and the side wall of the dispensing disc is uniformly provided with a plurality of joints along the circumference.

[0016] Preferably, the belt of the bottle conveyor is provided with a toothed structure, and the rotating shaft of the feeding disc is provided with a gear, which meshes with the toothed structure.

[0017] The beneficial effects of this invention are as follows: During the transport of the bottle to the next process via the conveyor line, the bottle enters the conveyor line through a guide channel, where it faces the inspection mechanism and completes the inspection. After inspection, the bottle is then reintroduced onto the conveyor line via the guide channel. Compared with existing technologies, this invention enables online airtightness inspection of the bottle, reduces the number of process steps involved in bottle production, and improves production efficiency.

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 , Figure 2 As shown, a bottle airtightness testing device includes a frame 2 attached to the side of the bottle conveyor line 1. A testing mechanism 3 and a transport line 4 are arranged from top to bottom on the frame 2. The testing mechanism 3 is a common testing scheme for pressure-type airtight plugs in the prior art, and will not be described in detail in this invention. The transport line 4 is preferably arranged parallel to the bottle conveyor line 1. For example, the transport line 4 can be a conveyor belt, and the bottle conveyor line 1 can also be a conveyor belt or a chain conveyor.

[0023] A guiding mechanism 5 is provided between transport line 4 and bottle conveyor line 1. The guiding mechanism 5 is adapted to form a guiding channel 6, within which the bottle can flow along the transport direction. For example, as the bottle is transported to the next process via bottle conveyor line 1, the bottle will adhere to the guiding mechanism 5. Pushed by subsequent bottles, the bottle will enter transport line 4 through the first guiding channel 6 until it is vertically aligned with the detection mechanism 3. Subsequently, the airtight plug of the detection mechanism 3 presses down to detect the airtightness of the bottle. Driven by transport line 4, the detected bottle will again come into contact with the guiding mechanism 5 and, under the thrust, re-enter bottle conveyor line 1 through the second guiding channel 6.

[0024] It is understandable that during the airtightness test of the bottle in the middle, the bottle conveyor line 1 can be kept in a continuous state of motion. On the one hand, the subsequent bottles can be transported to the first guide channel 6; on the other hand, the bottles that have completed the test can be transported to the subsequent equipment for processing.

[0025] In some embodiments, the guiding mechanism 5 may preferably include two guide plates 7 arranged in parallel and spaced apart. For example, the two guide plates 7 may preferably be made of an elastic material. In possible examples, the guide plates 7 may actually be in the form of rubber bands. The two guide plates 7 define the aforementioned guiding channel 6, and the bottle is not easily damaged by impact at the guiding channel 6.

[0026] Correspondingly, support mechanisms 8 are provided at both ends of the bottle conveying line 1 and the transport line 4. Support mechanisms 8 are also provided on the transport line 4. The support mechanisms 8 are used to support and install the guide plate 7 made of elastic material. In particular, the support mechanism 8 is not required at the guide channel 6, thus providing the bottle with the maximum flexible buffering capacity.

[0027] The support mechanism 8 preferably includes two symmetrically arranged bases 9, and a support plate 19 is provided on the side wall of the base 9. The guide plate 7 can be provided on the side wall of the support plate 19 by means of adhesive or bolt connection.

[0028] In a preferred embodiment, a connecting hole 10 is provided on the side wall of the base 9, and a guide rod is provided on the side wall of the support plate 19 opposite to the guide plate 7. The guide rod is inserted into the connecting hole 10. In addition, a locking member 12 is provided on the base 9 for locking the relative position of the connecting rod 11. When the diameter of the bottle passing through varies greatly, the locking member 12 can be operated to release the connecting rod 11. At this time, the connecting rod 11 can slide within the connecting hole 10, thereby adjusting the distance between the two guide plates 7, that is, the width of the guide channel 6 can be adjusted to adapt to the stable guidance flow of bottles with different diameters.

[0029] For example, a threaded hole is provided on the top surface of the base 9, which is connected to the connecting hole 10, and the locking member 12 preferably includes a tightening bolt 13 threaded in the threaded hole, and the position is locked by tightening the bolt 13 to press the connecting rod 11.

[0030] To reduce the contact between bottles within the guide channel 6, a bottle-pushing mechanism 14 is preferably provided between the bottle conveyor line 1 and the transport line 4. This mechanism actively pushes the bottles through the guide channel 6. For example, the bottle-pushing mechanism 14 preferably includes a rotatable dispensing disc 15, with several engagement ports 16 evenly distributed circumferentially on its side wall. It is conceivable that as the dispensing disc 15 rotates, the engagement ports 16 engage with the bottles, and the bottles are pushed forward with the rotation, rather than relying entirely on the mutual pushing of subsequent bottles, thus reducing collisions between bottles.

[0031] In a specific example, the feeding disc 15 can rotate under the drive of a motor. Alternatively, the bottle conveyor line 1 can preferably have a toothed structure 17 on its belt, and a gear 18 on the shaft of the feeding disc 15, with the gear 18 meshing with the toothed structure 17. As mentioned above, the bottle conveyor line 1 can operate continuously, thus the feeding disc 15 rotates under the transmission of the toothed structure 17 and the gear 18. Furthermore, the gear 18 is not limited to a single gear; for example, it can be a set of 18 gears, especially to achieve a speed reduction effect, making the rotation of the feeding disc 15 slow. Moreover, by selecting different numbers of gears 18 to mesh, the desired rotation direction of the feeding disc 15 can be achieved; this is something that those skilled in the art should know and understand, and therefore will not be elaborated further.

[0032] For example, a rubber strip may be attached circumferentially to the side wall of the feeding disc 15 to reduce impact damage to the bottle. The structure of the toothed structure 17 is similar to that of a toothed rack.

[0033] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
