Description

Technical Field

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

[0002] After being produced, food, medical devices, electronic components and other items need to be packed into packaging bags and sealed to make products. The sealed packaging bags can help the items block moisture and gas in the external environment, thereby preventing the items from being contaminated and damaged during transportation, storage and sales. Therefore, product sealing testing is also one of the procedures to verify whether the product is qualified.

[0003] Chinese utility model CN214502824U discloses a device for testing the sealing properties of puffed food packaging. The utility model sets a driving motor, which drives the lead screw to rotate, so that the lifting plate moves downward to squeeze the puffed food. If the package leaks, the gas in the package will be discharged to the outside after the package is compressed, so that the volume of the package is reduced. During the detection process, if the lifting plate exerts too much pressure on the puffed food, the product with qualified sealing properties will be squeezed and broken; if the lifting plate exerts too little pressure on the puffed food, the product with less damaged packaging cannot be discovered in time, so the detection accuracy of the device is low and the product is easily damaged.

[0004] In addition, after the above device completes the sealing test of the product, the staff needs to manually take the product out of the device, resulting in low efficiency of the device in testing the packaging. Utility Model Content

[0025] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0026] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0027] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0028] refer to Figures 1 to 7 The product sealing detection device according to a preferred embodiment of the present invention will be described in detail below. The product sealing detection device includes a device body 10, at least one loading member 20 and a power mechanism 30.

[0029] The device body 10 includes a device body 11, and the device body 11 forms a liquid storage chamber 1101. The liquid storage chamber 1101 is used to hold liquid, such as aqueous solution. The loading member 20 forms a placement chamber 201, and the placement chamber 201 formed by the loading member 20 is used to store products. The loading member 20 is drivingly connected to the power mechanism 30, and the power mechanism 30 is configured to drive the loading member 20 to move from above the liquid surface to below the liquid surface and from below the liquid surface to above the liquid surface.

[0030] Specifically, when the power mechanism 30 drives the loading part 20 to sink from above the liquid level to below the liquid level in the liquid storage chamber 1101, the product is tested for air tightness; when the power mechanism 30 drives the loading part 20 to move from below the liquid level to above the liquid level, the product is placed in the loading part 20.

[0031] It is worth mentioning that the loading part 20 also forms a plurality of through holes 202 connected to the placement chamber 201. When the loading part 20 sinks below the liquid surface, the liquid can enter the placement chamber 201 through the through holes 202, so that the liquid squeezes the packaging bag of the product. If the packaging bag of the product placed in the placement chamber 201 is damaged, the gas in the packaging bag of the product will escape from the packaging bag under the action of the hydraulic pressure, and will float to the liquid surface after bubbles are generated under the liquid; if the packaging bag of the product placed in the placement chamber 201 is intact, no bubbles will be generated after the product sinks to the liquid surface. When the loading part 20 moves above the liquid surface, the liquid in the placement chamber 201 can be quickly discharged through the through holes 202 to control the product.

[0032] It is worth mentioning that after the products are tested by the device, the gas in the packaging bags of the products that do not meet the sealing standards escapes under the action of hydraulic pressure. Therefore, after being removed from the device, the packaging bags fit the products and are flat as a whole. Products that meet the sealing standards are bulging overall due to the gas in the bags. Therefore, the inspectors can observe the degree of bulging of the products after the sealing test to determine whether the product's sealing test meets the standards.

[0033] In one embodiment, the device body 11 has a high end portion 111 and a low end portion 112 lower than the high end portion 111, wherein the device body 11 forms an opening 1102 at the high end portion 111 that communicates with the liquid storage chamber 1101. The inspector checks the bubbles under the liquid and on the liquid surface through the opening 1102 to determine whether the sealing of the product meets the standard.

[0034] Preferably, the device body 11 is made of a transparent material, such as tempered glass, so that the inspector can observe the bubbles under the liquid and on the liquid surface through the device body 11 with naked eyes.

[0035] Preferably, the loading member 20 forms a taking port 203 communicating with the placing cavity 201 . The inspector takes or places the product from the taking port 203 through the opening 1102 .

[0036] Specifically, the loading member 20 includes a box body 21 , and the box body 21 forms the placement cavity 201 and the taking port 203 .

[0037] In one embodiment, the taking port 203 is formed at the top of the box body 21, and the loading piece 20 also includes a cover body, which is installed on the box body 21 in an openable and closable manner. The cover body is used to cover or open the taking port 203, and the cover body is used to prevent the product from being moved out of the placement cavity 201 through the taking port 203 due to buoyancy.

[0038] As a deformable form, the box body 21 forms the access opening 203 on the side, and the cover body may not be provided at this time. The inspector can access the product from the side of the box body 21, and when the product sinks below the liquid surface, the top wall of the box body 21 helps the product overcome the buoyancy to prevent the product from floating out of the placement cavity 201. When the inspector uses this embodiment to perform a sealing test, the operation of opening and closing the cover body is eliminated, so as to facilitate the product access and improve the test efficiency, and also save the manufacturing cost of the device. In order to facilitate those skilled in the art to understand the subsequent technical solutions, the following embodiments are described on this basis.

[0039] Preferably, the loading part 20 further includes at least one partition 22, which is installed in the placement cavity 201 formed by the box body 21 to divide the placement cavity 201 into multiple areas. Products are distributed to each area, and the inspection personnel observe whether bubbles escape from the corresponding area to determine the airtightness of the product. In other words, a single loading part 20 can store multiple products, that is, multiple products can be tested for sealing at the same time at a time to improve the efficiency of sealing testing.

[0040] Specifically, the power mechanism 30 includes a driving member 31 and a mounting member 32, wherein the mounting member 32 is drivingly connected to the driving member 31, and the loading member 20 is mounted on the mounting member 32. The driving member 31 drives the mounting member 32 to move, so that the mounting member 32 drives the loading member 20 to move from above the liquid surface to below the liquid surface and from below the liquid surface to above the liquid surface.

[0041] In one example, the driving member 31 is implemented to include a motor.

[0042] In one embodiment, the mounting member 32 is mounted on the device body 11, and the mounting member 32 extends between the high end portion 111 and the low end portion 112. The portion of the mounting member 32 corresponding to the low end portion 112 extends below the liquid surface, and the portion of the mounting member 32 corresponding to the high end portion 111 extends above the liquid surface. In this way, when the driving member 31 drives the mounting member 32 to operate, the mounting member 32 drives the loading member 20 to move from above the liquid surface to below the liquid surface and then moves from below the liquid surface to above the liquid surface.

[0043] In one example, the mounting member 32 is implemented to include a conveyor belt.

[0044] refer to Figure 2As a deformable device, the mounting member 32 is rotatably connected to the driving member 31, and the mounting member 32 has at least one mounting portion 321. The loading member 20 is rotatably mounted on an end of the mounting portion 321 away from the driving member 31. When the driving member 31 drives the mounting portion 321 to rotate vertically upward, the loading member 20 moves above the liquid surface, and when the driving member 31 drives the mounting portion 321 to rotate vertically downward, the loading member 20 is immersed below the liquid surface.

[0045] Preferably, the driving member 31 has an output shaft 311, and the mounting member 32 has a plurality of mounting portions 321, which are spaced apart in the circumferential direction of the output shaft 311, and the loading member 20 is mounted on one end of each mounting portion 321 away from the output shaft 311. In this way, when the driving member 31 drives the mounting member 32 to rotate continuously, the products placed on each loading member 20 can be successively tested for air tightness, so as to improve the efficiency of air tightness testing.

[0046] Furthermore, the product sealing detection device also includes at least one ejection mechanism 40 .

[0047] When the loading member 20 moves to a predetermined position above the liquid level, the taking port 203 formed by the loading member 20 corresponds to the edge position of the opening 1102. The ejecting mechanism 40 includes a pushing member 41 and an ejecting member 42. At least part of the pushing member 41 is installed in the placement cavity 201, and the pushing member 41 is drivingly connected to the ejecting member 42. The ejecting member 42 is configured to drive the pushing member 41 to move toward or away from the taking port 203.

[0048] Specifically, when the driving member 31 drives the loading member 20 to move to the predetermined position above the liquid level through the mounting member 32, the ejecting member 42 drives the pushing member 41 to approach the taking port 203, so that the product is squeezed out of the placement cavity 201 by the pushing member 41 and moved out of the device body 11 through the opening 1102. In this way, after the product completes the sealing test, the ejecting mechanism 40 moves the product out of the device body 11 without the need for the inspector to manually remove it. After the product is moved out of the placement cavity 201, the ejecting member 42 drives the pushing member 41 to move in the direction away from the taking port 203 to reset, so that the remaining products can continue to be tested for sealing.

[0049] Preferably, the device body 10 further comprises a guide member 12. The guide member 12 forms a guide slide 1201 and a discharge port 1202 of the guide slide 1201. The guide member 12 is mounted on the device body 11 and keeps the guide slide 1201 in communication with the opening 1102. When the loading member 20 moves to the predetermined position, the taking port 203 corresponds to an end of the guide member 12 away from the discharge port 1202 and is in communication with the guide slide 1201 through the opening 1102, and an end of the guide member 12 forming the discharge port 1202 is lower than an end of the guide member 12 away from the discharge port 1202, so that the product pushed out of the loading member 20 by the ejection mechanism 40 falls into the guide slide 1201 from the opening 1102, and the product falling into the guide slide 1201 moves toward the discharge port 1202 under the action of gravity to buffer the discharge of the product.

[0050] refer to Figure 2 and Figure 3 In one example, the ejection member 42 is implemented as a cylinder, wherein one end of a piston rod of the cylinder extending out of the cylinder body is connected to the pusher 41 .

[0051] refer to Figures 4 to 7 Preferably, the pusher 41 includes a push plate 411 and a sleeve 412. The push plate 411 is installed in the placement cavity 201. The box body 21 forms a through hole 2101 on a side away from the taking port 203, and the sleeve 412 passes through the through hole 2101 and is connected to the push plate 411.

[0052] Preferably, the box body 21 forms at least one anti-rotation convex strip 211 on the hole wall of the insertion hole 2101. The inner wall of the sleeve 412 forms at least one anti-rotation groove 41201, and the sleeve 412 is inserted into the insertion hole 2101 in a manner that the anti-rotation convex strip 211 is engaged with the anti-rotation groove 41201.

[0053] As a deformable structure, the ejection member 42 includes a reciprocating screw rod 421 and a rotation driving component 422, and the reciprocating screw rod 421 is rotatably mounted on the sleeve 412. The reciprocating screw rod 421 is rotationally connected to the rotation driving component 422. When the reciprocating screw rod 421 is rotated by the rotation driving component 422, the sleeve 412 moves along its own axial direction under the limiting action of the rotation-stopping convex strip 211 and the rotation-stopping groove 41201 to approach or deviate from the taking port 203.

[0054] Specifically, when the loading member 20 moves to the predetermined position, the driving component 422 drives the reciprocating screw 421 to rotate and the sleeve 412 moves toward the direction close to the taking port 203 under the limiting action of the anti-rotation protrusion 211 and the anti-rotation groove 41201, so that the product is pushed out of the placement cavity 201 by the push plate 411; when the loading member 20 rotates away from the predetermined position, the sleeve 412 drives the push plate 411 to reset.

[0055] In one embodiment, the rotation driving component 422 is implemented to include a motor.

[0056] In another embodiment, the center of gravity of the loading member 20 is close to the bottom wall of the box body 21. An arc groove 1103 is formed on the side wall of the device body 11 facing the insertion hole 2101. The device body 11 forms a plurality of spaced teeth on the side wall of the arc groove 1103. A mounting groove 42101 is formed at one end of the reciprocating screw rod 421 away from the sleeve 412, and a plurality of spaced engaging grooves 42102 are formed on the inner wall of the mounting groove 42101. The driving component 422 includes a force storage member 4221, a driven gear 4222, a connecting shaft 4223 and a ratchet 4224. A stop protrusion 42231 is formed at one end of the connecting shaft 4223, and an end of the connecting shaft 4223 where the stop protrusion 42231 is formed extends into the mounting groove 42101. The force storage member 4221 and the driven gear 4222 are both mounted on one end of the connecting shaft 4223 extending out of the mounting slot 42101, and the force storage member 4221 and the driven gear 4222 can move into and out of the arc slot 1103. When the driven gear 4222 moves into the arc slot 1103, the driven gear 4222 meshes with the teeth. The ratchet 4224 is mounted on the connecting shaft 4223, and one end of the ratchet 4224 away from the connecting shaft 4223 extends into the clamping slot 42102, and the stop protrusion 42231 can rotate to abut against any side of the ratchet 4224.

[0057] Specifically, when the driving member 31 drives the mounting portion 321 to rotate vertically upward, the loading member 20 keeps the bottom wall of the box body 21 vertically downward under the action of gravity. When the power mechanism 30 drives the loading member 20 to move downward to a predetermined height, the lifting mechanism 40 abuts against the mounting portion 321, so that the loading member 20 rotates and has a tendency to rotate to the bottom wall of the box body 21 vertically downward during the process in which the power mechanism 30 continues to drive the loading member 20 to move. Furthermore, when the rotation direction of the loading member 20 deviates from the distribution direction of the mounting portion 321, the loading member 20 rotates to a state with the bottom wall of the box body 21 vertically downward, and the force storage member 4221 and the driven gear 4222 move into the arc groove 1103 from one end of the arc groove 1103 close to the lower end 112, and the driven gear 4222 engages with the meshing teeth; so that while the loading member 20 drives the ejection mechanism 40 to rotate with the output shaft 311 as the axis, the driven gear 4222 and the connecting shaft 4223 rotate in a preset direction, and the force storage member 4221 contracts through the connecting shaft 4223 and has a tendency to drive the connecting shaft 4223 to rotate in the opposite direction; at the same time, the stop protrusion 42231 abuts against one side of the pawl 4224, and the pawl 4224 is pushed by the groove wall of the engaging groove 42102 and idles.

[0058] When the force storage member 4221 and the driven gear 4222 move out from one end of the arc groove 1103 away from the lower end 112, the driven gear 4222 loses the meshing relationship with the gear, and the force storage member 4221 drives the driven gear 4222 to reverse through the connecting shaft 4223, and the stop protrusion 42231 abuts against the other side of the ratchet 4224 and pushes the groove wall of the engaging groove 42102 through the ratchet 4224 to rotate the reciprocating screw 421, and the sleeve 412 moves along its own axial direction under the limiting action of the stop protrusion 211 and the stop groove 41201.

[0059] In one example, the force storage member 4221 is implemented to include a spring.
