Description

Technical Field

[0001] This application relates to the field of cosmetic processing technology, and in particular to an electromagnetic induction sealing device with a rejection function. Background Technology

[0002] Electromagnetic induction sealing devices utilize the principle that a powerful eddy current magnetic field is generated when an electromagnetic field comes into contact with a metal object. This causes the metal to heat up instantly, achieving magnetocaloric conversion. Through electromagnetic induction, the aluminum foil heats up, melting the adhesive film underneath and bonding it to the bottle opening, achieving continuous, rapid, non-contact sealing. Currently, it is widely used in the pharmaceutical, pesticide, food, health product, beverage, cosmetic, and chemical industries.

[0003] A related technology, CN219728720U, discloses an electromagnetic induction sealing machine with a rejection function, comprising: a support and positioning mechanism; a conveying mechanism disposed inside the support and positioning mechanism; a sealing mechanism disposed on the back of the conveying mechanism; a rejection limiting mechanism disposed on the top of the conveying mechanism; the support and positioning mechanism includes: a support block with a rectangular groove on its top; four support seats, respectively fixedly connected to the four corners of the bottom of the support block; and a control panel mounted on the front of the support block. This electromagnetic induction sealing machine with a rejection function utilizes a groove in the rejection limiting mechanism to allow gears to move horizontally within the groove via a rack, adjusting the position of the fixed rod and the mounting sleeve. The telescopic rod and the movable sleeve allow for length adjustment of the mounting sleeve, and the fixed rod limits the sealing range of motion.

[0004] While the electromagnetic induction sealing device with rejection function mentioned above can limit the sealing range, it lacks a means to pre-detect the packaging bottles entering the sealing area. This means that although the sealing range can be adjusted, the sealing effect may still be unsatisfactory due to differences in the size of the packaging bottles. Utility Model Content

[0005] To address the issue that current electromagnetic induction sealing devices with rejection functions lack the means to pre-detect packaging bottles entering the sealing area due to their design features, resulting in unsatisfactory sealing effects despite the ability to adjust the sealing range, this application provides an electromagnetic induction sealing device with rejection functions.

[0006] The electromagnetic induction sealing device with rejection function provided in this application adopts the following technical solution: it includes a feeding belt, a discharge belt arranged relative to the feeding belt, a support roller arranged between the feeding belt and the discharge belt, a rejection mechanism arranged on one side of the support roller, a defective conveyor belt arranged on the other side of the support roller relative to the rejection mechanism, a control box fixedly arranged on the feeding belt, a detection instrument connected to the control box, and a sealing mechanism fixedly arranged on one side of the discharge belt.

[0007] By adopting the above technical solution, the packaging bottles to be sealed are first conveyed by the feeding belt to the detection area of ​​the detection instrument. After passing the detection, the packaging bottles of normal specifications will continue to be conveyed by the conveyor belt to the discharge belt and sealed by the sealing mechanism. If packaging bottles of non-standard specifications are found, the rejection mechanism will be triggered to push them to the defective product conveyor belt, thereby eliminating non-compliant products and ensuring that the packaging bottles that are finally sealed meet the requirements.

[0008] As a preferred embodiment, the support roller is configured as a cylindrical structure, with the feed end of the support roller positioned relative to the rejection mechanism and the discharge end of the support roller positioned relative to the defective product conveyor belt.

[0009] By adopting the above technical solution, the support roller adopts a cylindrical structure, which ensures that the packaging bottles can pass smoothly without being affected by friction. The feed end of the support roller is close to the rejection mechanism, allowing the packaging bottles to roll or slide smoothly on the support roller before being forced into the defective product conveyor belt by the force of the rejection mechanism. The discharge end of the support roller corresponds to the defective product conveyor belt, ensuring that the packaging bottles can smoothly transition onto the defective product conveyor belt. The reason for this design is that the cylindrical support roller can effectively reduce the friction between itself and the packaging bottles, thereby avoiding the packaging bottles getting stuck or damaged due to friction.

[0010] As a preferred embodiment, the rejection mechanism includes a pusher plate, an "L"-shaped rotating support rod fixedly connected to the pusher plate, a first mounting base rotatably connected to the lower end face of the rotating support rod, a slider fixedly connected to the first mounting base, a support base slidably connected to the slider, a mounting plate fixedly connected to the lower end face of the support base, a second mounting base rotatably connected to the upper end of the rotating support rod, an electric push rod connected to the second mounting base and the second mounting base, and a mounting bracket fixedly disposed on the upper end face of the support base for fixing the electric push rod. The mounting plate is fixedly disposed on one side of the support roller.

[0011] By adopting the above technical solution, the rotating support rod slides up and down within the support seat via the first mounting base and is connected to the electric push rod via the second mounting base. The mounting plate is fixed to one side of the support roller, and the support seat is supported by the mounting plate so that the slider can slide within the support seat. The push of the electric push rod causes the rotating support rod to rotate, which in turn pushes the defective packaging bottles from the support roller to the defective product conveyor belt via the pusher plate.

[0012] As a preferred embodiment, the telescopic shaft of the electric push rod passes through the mounting bracket and connects to the second mounting base, and the telescopic shaft is fixedly connected to the second mounting base.

[0013] By adopting the above technical solution, the telescopic shaft of the electric push rod passes through the mounting bracket and connects to the second mounting bracket. The telescopic shaft is fixedly connected to the second mounting bracket and is used to push the second mounting bracket. After receiving the push from the telescopic shaft, the second mounting bracket generates a thrust on the rotating support rod connected to it. At this time, the thrust of the rotating support rod is transmitted to the slider, causing it to translate in a straight line within the support bracket. Finally, the movement of the slider drives the movement of the pusher plate, realizing the pushing of defective packaging bottles from the support roller to the defective product conveyor belt.

[0014] As a preferred embodiment, the support base is provided with a groove that matches the slider, and the inner wall of the groove is a smooth arc surface.

[0015] By adopting the above technical solution, the function of the support base is to provide guidance and support for the sliding of the slider. The smooth arc surface groove on it, which is adapted to the slider, can reduce the frictional resistance of the slider during the sliding process, making the sliding smoother and more stable. The smooth arc surface design of the inner wall of the groove can effectively reduce wear, extend service life, and evenly distribute pressure to prevent the slider from deviating or getting stuck during the movement.

[0016] As a preferred embodiment, a buffer pad is provided at the end of the pusher plate away from the end connected to the rotating support rod, and the buffer pad is in contact with the pusher plate through a polymer adhesive.

[0017] By adopting the above technical solution, the cushioning pad is fixedly connected to the pusher plate using a polymer adhesive. The main function of the cushioning pad is to prevent the pusher plate from making direct hard contact with the packaging bottle, thereby preventing damage to the packaging bottle during the push-out process. When the pusher plate pushes the packaging bottle, the cushioning pad can absorb part of the impact force, reducing the damage that may be caused by hard contact and ensuring the integrity of the packaging bottle.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. The feeding belt is used to transport the packaging bottles to be sealed; the discharge belt is used to transport the packaging bottles that have passed the inspection to the sealing mechanism for sealing.

[0020] 2. The support roller is located between the feeding belt and the discharge belt to support the conveying path of the packaging bottles. The rejection mechanism is located on one side of the support roller. When the detection instrument detects packaging bottles of non-standard specifications, the rejection mechanism will push these non-standard packaging bottles to the defective product conveyor belt to prevent them from entering the normal sealing process. The defective product conveyor belt is used to transport rejected packaging bottles separately.

[0021] 3. A detection instrument is fixedly installed on the control box, which can automatically detect the specifications of the packaging bottles, ensuring that only packaging bottles that meet the specifications can continue to be conveyed through the support roller area. The sealing mechanism is fixedly set on one side of the discharge belt and is used to seal the packaging bottles that have passed the detection and continue to be conveyed.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This application discloses an electromagnetic induction sealing device with a rejection function. It includes a feeding belt 11, a discharge belt 12 disposed relative to the feeding belt 11, a support roller 2 disposed between the feeding belt 11 and the discharge belt 12, a rejection mechanism disposed on one side of the support roller 2, a defective product conveyor belt 13 disposed on the other side of the support roller 2 relative to the rejection mechanism, a control box 3 fixedly disposed on the feeding belt 11, a detection instrument 31 connected to the control box 3, and a sealing mechanism 8 fixedly disposed on one side of the discharge belt 12. In this invention, the packaging bottles to be sealed are first conveyed by the feeding belt 11 to the detection area of ​​the detection instrument 31. After passing the detection, packaging bottles of normal specifications will continue to be conveyed by the conveyor belt to the discharge belt 12 and sealed by the sealing mechanism 8. Packaging bottles of abnormal specifications will trigger the rejection mechanism to push them to the defective product conveyor belt 13, thereby rejecting non-compliant products and ensuring that the finally sealed packaging bottles all meet the requirements.

[0030] Please refer to details. Figure 1 and Figure 2 The support roller 2 is cylindrical, with its inlet end positioned relative to the rejection mechanism and its outlet end relative to the defective product conveyor belt 13. The cylindrical shape of the support roller 2 ensures smooth passage of the bottles without friction. The inlet end of the support roller 2 is close to the rejection mechanism, allowing the bottles to roll or slide smoothly on it before being forced onto the defective product conveyor belt 13. The outlet end of the support roller 2 corresponds to the defective product conveyor belt 13, ensuring a smooth transition of the bottles onto it. This design effectively reduces friction between the cylindrical support roller 2 and the bottles, preventing jamming or damage caused by friction. The working principle is that after being subjected to the force of the rejection mechanism, the bottles are guided by the support roller 2 to smoothly transfer to the defective product conveyor belt 13 without significant friction, ensuring smooth transport and the integrity of the bottles.

[0031] Please refer to details. Figure 3 , Figure 4 and Figure 5The rejection mechanism includes a pusher plate 41, an "L"-shaped rotating support rod 42 fixedly connected to the pusher plate 41, a first mounting base 411 rotatably connected to the lower end face of the rotating support rod 42, a slider 51 fixedly connected to the first mounting base 411, a support base 52 slidably connected to the slider 51, a mounting plate 7 fixedly connected to the lower end face of the support base 52, a second mounting base 421 rotatably connected to the upper end of the rotating support rod 42, an electric push rod 61 connected to the second mounting base 421, and a mounting support 611 fixedly disposed on the upper end face of the support base 52 for fixing the electric push rod 61. The mounting plate 7 is fixedly disposed on one side of the support roller 2. The rotating support rod 42 slides up and down in the support base 52 through the first mounting base 411 and is connected to the electric push rod 61 through the second mounting base 421. The mounting plate 7 is fixed on one side of the support roller 2, and the support base 52 is supported by the mounting plate 7 so that the slider 51 slides in the support base 52. The electric push rod 61 causes the rotating support rod 42 to rotate, which in turn pushes the defective packaging bottles from the support roller 2 to the defective product conveyor belt 13 via the pusher plate 41. In this way, the mounting bracket 611 fixes the electric push rod 61 to ensure its stable operation. The first mounting base 411 and the second mounting base 421 ensure the rotation of the rotating support rod 42. The sliding cooperation between the slider 51 and the support base 52 ensures the stable linear motion path of the pusher plate 41, thereby achieving the precise rejection of defective packaging bottles.

[0032] Please refer to details. Figure 3 , Figure 4 and Figure 5 The telescopic shaft of the electric push rod 61 passes through the mounting support 611 and connects to the second mounting base 421, and is fixedly connected to the second mounting base 421. The telescopic shaft is used to push the second mounting base 421. After receiving the push from the telescopic shaft, the second mounting base 421 generates a thrust on the rotating support rod 42 connected to it. At this time, the thrust of the rotating support rod 42 is transmitted to the slider 51, causing it to move linearly within the support base 52. Finally, the movement of the slider 51 drives the movement of the pusher plate 41, achieving precise material pushing. The working principle is as follows: the electric push rod 61 transmits power to the second mounting base 421 through the telescopic shaft, pushing the second mounting base 421 to move. Then, through the connection of the rotating support rod 42, it works together with the slider 51 to make the slider 51 move within the support base 52. Finally, the slider 51 drives the push plate 41 to move, thereby removing unqualified packaging bottles.

[0033] Please refer to details. Figure 3 , Figure 4 and Figure 5The support base 52 is provided with a groove 521 that is adapted to the slider 51. The inner wall of the groove 521 is set as a smooth arc surface. The function of the support base 52 is to provide guidance and support for the slider 51 to slide. The smooth arc surface groove 521 that is adapted to the slider 51 can reduce the frictional resistance of the slider 51 during the sliding process, making the sliding smoother and more stable. The smooth arc surface design of the inner wall of the groove 521 can effectively reduce wear, extend service life, and evenly distribute pressure to prevent the slider 51 from deviating or getting stuck during the movement.

[0034] Please refer to details. Figure 3 , Figure 4 and Figure 5 A buffer pad is provided at the end of the pusher plate 41 away from the end connected to the rotating support rod 42. The buffer pad is in contact with the pusher plate via a polymer adhesive and is fixedly connected to the pusher plate 41 via the polymer adhesive. The main function of the buffer pad is to prevent the pusher plate 41 from making direct hard contact with the packaging bottle, thereby preventing damage to the packaging bottle during the push-out process. When the pusher plate 41 pushes the packaging bottle, the buffer pad can absorb part of the impact force, reduce the damage that may be caused to the packaging bottle due to hard contact, and ensure the integrity of the packaging bottle.

[0035] The implementation principle of an electromagnetic induction sealing device with rejection function in this application embodiment is as follows: During use, the packaging bottle to be sealed is first conveyed by the feeding belt 11 to the detection area of ​​the detection instrument 31. After passing the detection, the packaging bottle of normal specifications will continue to be conveyed by the conveyor belt to the discharge belt 12 and sealed by the sealing mechanism 8. If a packaging bottle of abnormal specifications is found, the rejection mechanism will be triggered to push it to the defective product conveyor belt 13, thereby rejecting products that do not meet the specifications. The working principle of the rejection mechanism is that the electric push rod 61 transmits power to the second mounting base 421 through the telescopic shaft, pushing the second mounting base 421 to move. Then, through the connection of the rotating support rod 42, it works together with the slider 51 to make the slider 51 translate within the support base 52. Finally, the slider 51 drives the push plate 41 to move, thereby realizing the rejection of unqualified packaging bottles.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
