Description

Technical Field

[0001] This utility model relates to the field of sealing equipment technology, and more specifically to a glass bottle sealing machine. Background Technology

[0002] In the food industry, the sealing process of packaging containers is a crucial step in ensuring product quality and extending shelf life. Sealing machines, as the core equipment for this process, operate based on electromagnetic induction technology: an alternating magnetic field is generated by an internal electromagnetic induction coil. When the aluminum foil (or tin foil) at the bottle opening enters the magnetic field, eddy currents are induced within the foil and instantly converted into high heat. This melts the sealing layer (such as a polyethylene layer) at the contact point between the aluminum foil and the bottle opening. After cooling, the foil fuses tightly with the bottle opening, forming a sealed structure. This achieves sealed preservation of the product, prevents leakage or spoilage of the contents, avoids the intrusion of external impurities, and reduces product loss during storage and transportation.

[0003] The plastic bottle aluminum foil sealing machine with publication number CN202864871U in the prior art adopts an automated production line with a conveyor belt. Compared with the sealing production line in the prior art, it is easy to operate, has a small error rate, and a low defect rate. However, this utility model still has the following problems: the bottles to be sealed are difficult to fix and are easy to tip over during the movement of the conveyor belt, which not only affects the sealing efficiency but may also lead to product loss and increase production costs. Therefore, this utility model proposes a glass bottle sealing machine. Summary of the Invention

[0004] The purpose of this invention is to provide a glass bottle sealing machine that can improve the stability of bottles during transportation and sealing, and reduce the defect rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A glass bottle sealing machine includes a base plate, side plates fixedly mounted on both sides of the upper end of the base plate, a transport section rotatably mounted between the side plates, the transport section including a transport belt rotatably connected to the side plates, a movable belt fixedly mounted outside the transport belt by a plurality of connecting columns, a plurality of through holes equidistantly provided on the movable belt, an end plate fixedly mounted on the upper end of each side plate, a cylinder device one fixedly mounted on the opposite ends of each end plate, the output end of the cylinder device one being fixedly connected to the fixed plate through the end plate, a top plate fixedly mounted between the upper ends of the end plates, a cylinder device two fixedly mounted on the upper end of the top plate, the output end of the cylinder device two being fixedly connected to the electromagnetic induction sealing body through the top plate.

[0006] Furthermore, the transport section also includes a rotating shaft rotatably connected to both sides of the side plate, the transport belt is sleeved on the outside of the rotating shaft, and a motor for driving the rotating shaft is fixedly installed on one side plate.

[0007] Furthermore, several triangular pieces are fixedly arranged around the perforation, and the triangular pieces are made of elastic rubber.

[0008] Furthermore, the spacing between the perforations is equal, the number of triangular pieces is 4-6, and the tips of the triangular pieces face the central axis of the perforations.

[0009] Furthermore, a number of protrusions are fixedly provided on the opposite side of the fixing plate, and the protrusions are made of rubber.

[0010] Furthermore, a plurality of support columns are rotatably provided between the side plates, and the upper ends of the support columns abut against the upper inner surface of the conveyor belt.

[0011] Furthermore, the lower end face of the electromagnetic induction sealing body is provided with an annular sensing area adapted to the mouth of the glass bottle to be sealed, and the inner diameter of the annular sensing area matches the outer diameter of the glass bottle mouth.

[0012] Beneficial effects: This utility model achieves initial fixation through the perforation of the moving belt and the elastic rubber triangular piece, and secondary clamping is achieved by the cylinder device driving the fixing plate, thus realizing double fixation. It completely solves the core problem of glass bottles being prone to tipping over during the conveying and sealing process in the existing conveyor belt sealing equipment represented by the prior art, which lacks a dedicated fixing mechanism. It avoids production interruptions and cost losses caused by bottle breakage and leakage of contents, while eliminating the safety hazards caused by glass fragments and ensuring the continuous and stable operation of the production line.

[0016] like Figure 1As shown in this specific embodiment, a glass bottle sealing machine includes a base plate 1, side plates 101 fixedly disposed on both sides of the upper end of the base plate 1, and a transport section rotatably disposed between the side plates 101. The transport section includes a transport belt 10 rotatably connected to the side plates 101, and a rotating shaft 2 rotatably connected to both sides of the side plates 101. The transport belt 10 is sleeved on the rotating shaft 2. A motor 13 for driving the rotating shaft 2 is fixedly disposed on one side plate 101. The output end of the motor 13 is connected to the rotating shaft 2 through a coupling. The start of the motor 13 can drive the rotating shaft 2 to rotate, thereby driving the transport belt 10 to run, thus realizing the automated conveying of glass bottles.

[0017] A number of support columns 9 are rotatably provided between the side plates 101. The upper end of the support column 9 abuts against the upper inner surface of the conveyor belt 10. The support column 9 provides upward support from the upper inner surface of the conveyor belt 10, which counteracts the downward pressure of the weight of the glass bottle and the moving belt 3 on the conveyor belt 10, prevents the conveyor belt 10 from deforming and sagging due to long-term load, and extends the service life of the conveyor belt 10. In addition, the evenly distributed support columns 9 keep the conveyor belt 10 running horizontally, prevent the moving belt 3 from tilting due to local sagging of the conveyor belt 10, and thus prevent the glass bottle from shifting its position due to tilting during transportation, ensuring the accuracy of subsequent positioning and sealing.

[0018] like Figures 1 to 3 As shown, a movable belt 3 is fixedly mounted on the outside of the conveyor belt 10 by several connecting posts 11. The connecting posts 11 are evenly distributed along the length of the conveyor belt 10, ensuring that the movable belt 3 is subjected to balanced force and preventing local weak connections that could lead to the movable belt 3 falling off or tilting. In addition, the evenly distributed connecting posts 11 ensure that the movable belt 3 moves completely synchronously with the conveyor belt 10 without relative displacement, preventing the movable belt 3 from jamming or the glass bottle conveying speed from fluctuating due to uneven connections, further improving the conveying stability. Several connecting posts 11 are evenly spaced on the movable belt 3. The device features a perforation 301, within which several triangular pieces 302 are fixedly arranged. These triangular pieces 302 are made of elastic rubber and form a preliminary fixation between the perforation 301 and the triangular pieces 302. This effectively solves the core problem in existing equipment where glass bottles are prone to tipping over during transport and sealing due to the lack of a dedicated fixing mechanism. It avoids production interruptions and cost losses caused by bottle breakage and leakage of contents, while also eliminating safety hazards from glass fragments and ensuring continuous and stable operation of the production line. The spacing between the perforations 301 is equal, and the number of triangular pieces 302 is 4-6. This "4-6 pieces" range balances clamping force and insertion ease. Fewer than 4 pieces result in insufficient clamping points and easy loosening, while more than 6 pieces lead to excessive insertion resistance. The tips of the triangular pieces 302 face the central axis of the perforation 301, naturally forming an inward clamping force direction, improving clamping reliability.

[0019] like Figures 1 to 2 As shown, each side plate 101 is fixedly provided with an end plate 5, and each end plate 5 is fixedly provided with a cylinder device 12 on the opposite end. The output end of the cylinder device 12 passes through the end plate 5 and is fixedly connected to the fixed plate 4. The activation of the cylinder device 12 can achieve double fixation of the bottle body, thereby further calibrating the position of the bottle body. Several protrusions 401 are fixedly provided on the opposite side of the fixed plate 4. The protrusions 401 are made of rubber. The setting of the protrusions 401 increases the contact points between the fixed plate 4 and the glass bottle, improves the clamping stability, and avoids the problem of easy slippage when clamped on a single plane. The rubber material is flexible and can buffer the clamping force to prevent the fixed plate 4 from rigidly contacting and scratching the bottle body. It is especially suitable for glass bottles with smooth surfaces or printed patterns.

[0020] A top plate 6 is fixedly installed between the upper ends of end plates 5. A second cylinder device 7 is fixedly installed on the upper end of the top plate 6. The output end of the second cylinder device 7 passes through the top plate 6 and is fixedly connected to the electromagnetic induction sealing body 8. Driven by the second cylinder device 7, the electromagnetic induction sealing body 8 moves downward in the vertical direction until its lower sealing working surface is completely in contact with the tin foil at the mouth of the glass bottle. The electromagnetic induction sealing body 8 has a built-in high-frequency electromagnetic induction coil, which generates an alternating magnetic field after being energized. When the tin foil is in this alternating magnetic field, eddy currents are induced inside it due to the electromagnetic induction effect. Due to the resistance of the tin foil, the eddy currents are quickly converted into heat energy during the flow process, causing the overall temperature of the tin foil to rise to 180-220℃ within 1-2 seconds (the specific temperature can be adjusted according to the thickness of the tin foil and the material of the surface sealing layer), providing a heat base for the subsequent melting of the sealing layer. In this process, heat is concentrated only on the tin foil and not transferred to the glass bottle body, preventing the glass bottle from cracking or deforming due to high temperatures. A thermoplastic sealing layer is pre-coated on the side of the tin foil facing the bottle opening. When the tin foil reaches the melting threshold of the sealing layer, it rapidly transforms from a solid to a molten state. At this time, the continuous downward pressure of the electromagnetic induction sealing body 8 ensures that the molten sealing layer fully fills the tiny gaps at the bottle opening and adheres tightly to the bottle opening surface. Simultaneously, the working surface of the sealing body is designed as a ring structure adapted to the bottle opening, ensuring that the molten sealing layer is evenly distributed around the bottle opening, preventing insufficient melting in certain areas that could lead to seal failure. After the sealing layer has melted, the electromagnetic induction sealing body 8 stops induction heating, and the cylinder device 7 drives the sealing body upwards to reset, disengaging from the tin foil. After disengagement, the molten sealing layer rapidly cools at room temperature, transforming back into a solid state, firmly bonding the tin foil to the bottle opening.

[0021] The lower end face of the electromagnetic induction sealing body 8 is provided with an annular sensing area that is adapted to the mouth of the glass bottle to be sealed. The inner diameter of the annular sensing area matches the outer diameter of the glass bottle mouth. Matching the inner diameter of the annular sensing area with the outer diameter of the glass bottle mouth allows the electromagnetic induction energy to be concentrated on the aluminum foil at the bottle mouth. This avoids energy waste due to an excessively large sensing area or leakage due to an excessively small sensing area. It ensures that the aluminum foil is heated and fused evenly, improves the sealing performance, and prevents leakage of contents.

[0022] Working principle: Workers insert glass bottles, already filled with product and with aluminum foil fitted at the neck, vertically into the perforations 301 of the moving belt 3, ensuring the bottom of the bottle makes stable contact with the moving belt 3. The elastic triangular pieces 302 inside the perforations 301 naturally clamp the bottle body, completing the initial fixation. The motor 13 is then switched on, driving the conveyor belt 10 via the rotating shaft 2. The conveyor belt 10 moves the moving belt 3 and the glass bottle at a preset speed towards the electromagnetic induction sealing body 8. During this process, the support column 9 rolls synchronously with the conveyor belt 10, continuously supporting it and ensuring the glass bottle moves vertically and stably. When the glass bottle moves directly below the electromagnetic induction sealing body 8, the motor 13 automatically stops, and the conveyor belt 10 pauses. The cylinder device 12 is activated, and its output pushes the fixing plate 4 towards the glass bottle. The secondary positioning is completed when the protrusion 401 on the fixed plate 4 makes close contact with the bottle body. Then, the second cylinder device 7 is activated, pushing the electromagnetic induction sealing body 8 downward to contact the aluminum foil at the bottle mouth and maintain it for a set time to complete the induction heating sealing. After sealing, the second cylinder device 7 first drives the electromagnetic induction sealing body 8 to return to the initial position. Then, the first cylinder device 12 drives the fixed plate 4 to return to both sides, releasing the clamp on the glass bottle. The motor 13 is activated again, and the conveyor belt 10 drives the sealed glass bottle to the discharge end. The operator or the automated mechanism takes the glass bottle out from the perforation 301 of the moving belt 3 to complete the discharge. At the same time, the next glass bottle to be sealed is transported to the sealing position by the moving belt 3, and the process of positioning, sealing and resetting is repeated to achieve continuous automated sealing.
