Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection equipment, in particular to a tea packaging bag airtightness detection device. Background Art

[0002] After the tea leaves are roasted, they are usually packed in vacuum seals by machines for easy storage and transportation. Existing packaging methods mostly involve vacuuming and injecting rare gases. In the packaging method involving injecting rare gases, if the vacuum packaging bag is damaged or poorly sealed, resulting in air leakage in the packaging bag, the tea leaves will become damp and moldy during storage or transportation. The packaging bag will lose its function of preserving and protecting the tea leaves, affecting the quality of the tea leaves. To address this situation, the tea packaging bag is usually placed in water for testing, and whether the tea packaging is leaking is determined by observing whether there are bubbles in the water. However, in existing testing devices, the tester places the sealed packaging bag on the water, and the sealed packaging bag will float on the water. The tester needs to press the bag into the water to observe the bag, which is very inconvenient and can easily break the sealed packaging bag.

[0003] The Chinese patent application number is CN202020222510.4, which discloses a tea packaging bag sealing detection device. The first motor drives the first rotating disk, and the second motor drives the second rotating disk to realize the water flow interruption and connection between the water storage chamber, the detection chamber and the water discharge chamber, thereby realizing the use of water to detect the air tightness of the packaging bag; in actual use, two motors are used to realize the air tightness detection, which is undoubtedly a waste of resources. Utility Model Content

[0004] The utility model aims to provide a tea packaging bag sealing detection device, which cleverly utilizes a servo motor to drive two rotating plates, thereby reducing the number of electrical equipment, thereby saving energy and reducing costs.

[0005] The embodiment of the utility model is realized through the following technical scheme: a tea packaging bag sealing detection device comprises a shell and a servo motor, wherein a water storage chamber, a detection chamber and a water discharge chamber are sequentially arranged inside the shell from top to bottom, the water discharge chamber and the water storage chamber are connected through a water pump, the water storage chamber and the detection chamber are separated by a first fixed partition, the detection chamber and the water discharge chamber are separated by a second fixed partition, a first rotating plate is arranged on one side of the first fixed partition, a second rotating plate is arranged on one side of the second fixed partition, the first rotating plate and the second rotating plate are driven to rotate by the servo motor through a rotating shaft, a first through hole is arranged on the first fixed partition, a second through hole is arranged on the second fixed partition, a third through hole is arranged on the first rotating plate, and a fourth through hole is arranged on the second rotating plate; when the first through hole and the third through hole are connected, the second through hole and the fourth through hole are misaligned; when the second through hole and the fourth through hole are connected, the first through hole and the third through hole are misaligned.

[0006] Furthermore, a material plate is provided in the detection chamber, and the material plate includes a supporting member, a matching part and a plurality of material troughs. The supporting member is fixedly connected to the matching part and the plurality of material troughs. An external thread is provided on the outer surface of the rotating shaft located in the detection chamber, an internal thread hole is provided on the matching part, a limiting hole is provided on the supporting member, a limiting rod is provided on the first fixed partition plate, the limiting rod is arranged through the limiting hole, and the matching part is sleeved on the rotating shaft by means of internal and external thread engagement. A pick-and-place door is provided on the side wall of the detection chamber, and the opening of the material trough is horizontally arranged.

[0007] Furthermore, the material trough and the supporting member are both made of transparent material.

[0008] Furthermore, the troughs are evenly distributed in a row on the circumference of the rotating shaft.

[0009] Furthermore, the bearing member is a flat plate, a supporting rod or a curved rod.

[0010] Furthermore, the detection chamber is made of transparent material.

[0011] Furthermore, a seal is provided between the servo motor and the rotating shaft.

[0012] Furthermore, the material trough is provided with a number.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0014] 1. Reduce the number of electrical equipment, save resources and reduce costs.

[0015] 2. In the Chinese patent with application number CN202020222510.4, it is necessary to fill the detection chamber with water to realize the air tightness test of the packaging bag. However, in actual use, water will always be lost, and it is impossible to achieve complete sealing of the equipment. Therefore, it is very costly to fill the detection chamber for each test. In the utility model, a material plate is cleverly provided to send the packaging bag into the water for air tightness test. At this time, there is no need to fill the detection chamber with water.

[0016] 3. In the Chinese patent with application number CN202020222510.4, the packaging bags are placed in the testing chamber in a disorderly manner. When filled with water, the packaging bags are still moving, and bubbles appear at this time. Then the inspectors will not be able to intuitively and quickly see which packaging bag has the bubbles, which will affect their judgment. In the utility model, a material trough is used to effectively separate each packaging bag for easy statistics and observation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example

[0029] like Figure 1-3As shown, a tea packaging bag sealing detection device includes a shell 10 and a servo motor 50. The shell 10 is provided with a water storage chamber 20, a detection chamber 30 and a water discharge chamber 40 from top to bottom. The water discharge chamber 40 and the water storage chamber 20 are connected through a water pump 80. The water storage chamber 20 and the detection chamber 30 are separated by a first fixed partition 22. The detection chamber 30 and the water discharge chamber 40 are separated by a second fixed partition 31. A first rotating plate 21 is provided on one side of the first fixed partition 22, and a second rotating plate 32 is provided on one side of the second fixed partition 31. The first rotating plate 21 and the second rotating plate 32 are driven to rotate by the servo motor 50 through a rotating shaft 52. The first fixed partition 22 is provided with a first through hole 24, and the second fixed partition 31 is provided with a second through hole 25. Two through holes 33, the first rotating plate 21 is provided with a third through hole 23, and the second rotating plate 32 is provided with a fourth through hole 34; when the first through hole 24 and the third through hole 23 are connected, the second through hole 33 and the fourth through hole 34 are misaligned; when the second through hole 33 and the fourth through hole 34 are connected, the first through hole 24 and the third through hole 23 are misaligned; that is to say, the first fixed partition plate 22 and the first rotating plate 21 are rotationally sealed and connected, and the connection between the water storage chamber 20 and the detection chamber 30 can only be achieved through the connection between the first through hole 24 and the third through hole 23. Similarly, the second fixed partition plate 31 and the second rotating plate 32 are rotationally sealed and connected, and the connection between the detection chamber 30 and the water discharge chamber 40 can only be achieved through the connection between the second through hole 33 and the fourth through hole 34. Figure 2 As shown in Figure 3, when the servo motor 50 drives the first rotating disk to rotate until the first through hole 24 and the third through hole 23 are connected, the rotation stops. At this time, the second through hole 33 and the fourth through hole 34 are misaligned, the detection chamber 30 and the drainage chamber 40 are not connected, and the water in the water storage chamber 20 will flow into the detection chamber 30 for air tightness detection; after completion, the servo motor 50 is driven to rotate until the second through hole 33 and the fourth through hole 34 are connected. At this time, the first through hole 24 and the third through hole 23 are misaligned, and water flows from the detection chamber 30 to the drainage chamber 40. Then, the water pump 80 is started to pump the water in the drainage chamber 40 into the water storage chamber 20 to achieve the purpose of reuse.

[0030] It should be emphasized here that if only the detection chamber 30 is used to realize the airtightness detection, then the detection chamber 30 must be filled with water, which is undoubtedly time-consuming and laborious. Therefore, in some embodiments, in order to reduce the time of filling the entire detection chamber 30 and avoid water waste, Figure 14, a material plate 60 is provided to assist in the air tightness detection of the packaging bag, and the specific structure is as follows: a material plate 60 is provided in the detection chamber 30, and the material plate 60 includes a bearing member 61, a matching portion 62 and a plurality of material slots 63, and the bearing member 61 is fixedly connected to the matching portion 62 and the plurality of material slots 63. In this embodiment, the bearing member 61 is a straight plate but not limited to a straight plate. For better observation, the bearing member 61 and the material slot 63 are made of transparent materials, such as transparent hard plastic. Further, for better observation of bubbles, the detection chamber 30 is also made of transparent materials; located in the detection chamber An outer surface of the rotating shaft 52 in 30 is provided with an external thread, an internal threaded hole is provided on the matching portion 62, a limiting hole 65 is provided on the bearing member 61, a limiting rod 70 is provided on the first fixed partition plate 22, the limiting rod 70 is arranged through the limiting hole 65, and the matching portion 62 is sleeved on the rotating shaft 52 by means of internal and external thread engagement. That is to say, the material plate 60, the rotating shaft 52 and the limiting rod 70 constitute a screw structure, and the up and down movement of the material plate 60 is realized by the rotation of the rotating shaft 52. A pick-up and placement door 90 is provided on the side wall of the detection chamber 30, and the opening 64 of the material trough 63 is arranged horizontally.

[0031] The whole working process is as follows:

[0032] 1: Reset, drive the servo motor 50 to raise the material plate 60 to the top of the detection chamber 30, and at the same time, the first through hole 24 and the third through hole 23 are misaligned; through the water injection port 51, the water storage chamber 20 is filled with water.

[0033] 2: Detection, place the packaging bag in the material trough 63 through the pick-and-place door 90, drive the servo motor 50, rotate the rotating shaft 52, and then connect the first through hole 24 and the third through hole 23. At this time, the second through hole 33 and the fourth through hole 34 are misaligned, and the water in the water storage chamber 20 flows into the detection chamber 30 and remains in the detection chamber 30. Due to the action of the screw, the material plate 60 will move downward with the packaging bag, immerse the packaging bag in water, and perform air tightness detection; It should be noted that the purpose of using a transparent material trough 63 and a carrier 61 is to facilitate the observation of bubbles. The first is the appearance of bubbles, and the second is that the bubbles will move upward and remain on the transparent carrier 61, which is more conducive to observation by the operator; it should also be emphasized that in order to ensure that water does not flow from the detection chamber 30 to the drain chamber 40 during the detection stage, the rotation period of the rotating shaft 52 is less than π, that is, less than one circle. In order to ensure that the material plate 60 can have sufficient vertical displacement during one circle of movement, the shaft diameter of the rotating shaft 52 should be set larger, thereby increasing the inclination angle of the teeth on the external gear on the rotating shaft 52 and the horizontal surface, which is convenient for the movement of the screw mechanism.

[0034] 3: Ending, after the inspection, the packaging bag is taken out through the pick-and-place door 90, and then the rotating shaft 52 is rotated until the second through hole 33 and the fourth through hole 34 are connected, and the water is discharged into the drainage chamber 40. It should be noted here that due to the existence of the screw mechanism, the servo motor 50 is driven in reverse at this time, and the water in the drainage chamber 40 is pumped to the water storage chamber 20 through the water pump 80.

[0035] During the entire use process, the following points are emphasized: 1: In order to ensure quick statistics and effective observation by the operator, the material troughs 63 should be evenly distributed in a circle on the axial side of the rotating shaft 52; 2: The material troughs 63 are numbered (not shown in the figure); 3: Due to the setting of the material plate 60, the pick-and-place door 90 can be set at a higher position in the detection chamber 30. In addition, seals should be provided at the connection between the pick-and-place door 90 and the side walls of the detection chamber 30.

[0036] Finally, it should be noted that in this embodiment, some basic waterproof defects are not described one by one, such as: a seal (not shown in the figure) is provided between the servo motor 50 and the rotating shaft 52.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
