[0002] A sealing device usually refers to a device or tool used to close the opening of a container to ensure the sealing of the contents of the container and prevent leakage or external contamination. A sealing device can be used in a variety of different occasions, such as food packaging, pharmaceutical packaging, industrial product packaging, etc. Common sealing devices include the following: aluminum foil sealers, heat seal sealers, screw cap sealers, etc. Among them, an aluminum foil sealer is a device that uses the principle of electromagnetic induction to achieve the bonding of aluminum foil to the bottle mouth. It is widely used in industries such as medicine, pesticides, food, cosmetics, and lubricants, and is especially suitable for product packages that require high sealing properties.

[0003] When sealing a product, the existing sealing device places the bottle to be sealed in the ring on the turntable for limiting the position, then rotates the turntable to rotate the bottle, and seals the bottle through the sealing device. However, the rings on the existing turntable are fixed, and bottles of different sizes cannot be placed, which reduces the usage scenario. At the same time, after the rings are replaced, the distance between the two rings will change. When the existing feeding device clamps the bottle, the distance between the bottles is fixed, and the bottle cannot be accurately placed according to the position of the rings.

[0032] Example 1

[0033] Reference Figure 1 - Figure 3, is the first embodiment of the utility model, which provides a sealing mechanism, including a processing component 100, including a processing table 101, a control unit is arranged on one side of the processing table 101, and the electronic components of the device can be controlled by the control unit, a conveying member 102 used in conjunction with the processing table 101, the conveying member 102 is a conveyor belt in the prior art, and the conveyor belt is an industrial automation equipment used to transport materials from one place to another during the production and logistics process. The working principle of the conveyor belt mainly includes the following aspects: driving mechanism, conveyor belt structure, support and guidance, material loading and unloading, control system, safety and monitoring, as well as maintenance and adjustment, a fixed frame 103 arranged on the conveying member 102 and the processing table 101, the fixed frame 103 is fixedly installed on the frame of the conveying member 102 and the processing table 101, and a rotating member 104 arranged on the processing table 101, and the product is sealed by the rotating member.

[0034] Specifically, the rotating member 104 includes a first motor 104a fixedly mounted on the bottom of the processing table 101, and the output end of the first motor 104a is configured to rotate at intervals and fixedly mounted on the top of the processing table 101. The supporting block 104b and the sealing member 104c are fixedly mounted. The sealing member 104c is a heat sealing machine in the prior art. The working principle of the heat sealing machine is mainly based on the heat sealing performance of thermoplastics. The following are the steps of its basic working principle: Heating element: The heat sealing machine usually includes one or more heating elements, which generate heat when working; Heat conduction: When the machine is started, the heating element transfers heat to the sealing part, usually through a heating plate or a heating belt; Plastic film softening: The plastic film (or other thermoplastic material) to be sealed is placed between the heating elements, and the heat causes the contact of the film to soften. The contact surface softens and melts; applying pressure: while heating, the machine applies a certain pressure to the softened film to ensure that the two layers of film materials fit tightly; cooling and solidification: the laminated film cools rapidly after the pressure is removed, so that the heat-sealed part solidifies and forms a permanent seal; sealing is completed: once the film cools and solidifies, the sealing process is completed, the package contents are sealed in the package, the turntable 104d rotatably mounted on the support block 104b, the mounting groove provided on the turntable 104d, the ring 104e used in conjunction with the mounting groove, the ring 104e is inserted into the mounting groove, the bottle is held by the ring 104e, and the arc plate 104f and the first spring 104g are symmetrically arranged in the mounting groove, and the arc plate 104f clamps the ring 104e through the reaction force of the first spring 104g.

[0035] Furthermore, a plurality of support blocks 104b and annular rings 104e are provided and are distributed in a ring shape. A rotating shaft is fixedly connected to the bottom end of the rotating disk 104d, and one end of the rotating shaft is fixedly connected to the output end of the first motor 104a.

[0036] Operation process: When in use, by placing the product in the ring 104e, the first motor 104a is started to drive the shaft to rotate, and the turntable 104d is driven to rotate by the shaft, so that the top product starts to rotate and moves to the bottom of the sealing member 104c. At this time, the turntable 104d stops rotating, and the bottle mouth of the product is sealed by the sealing member 104c, and then the turntable 104d is started again, and the cycle is repeated. At the same time, when sealing bottles of different sizes, the existing ring 104e on the turntable 104d is pulled upward so that the ring 104e can be moved from the installation The arc plate 104f is pulled out from the groove, and because it no longer contacts the circular ring 104e, it is reset and moved repeatedly by the reaction force of the first spring 104g. The time for replacing the circular ring 104e is just enough to make the first spring 104g smooth, and the circular rings 104e of different sizes are inserted into the installation groove. At the same time, the arc plates 104f on both sides are squeezed again, so that the arc plates 104f move toward the depth of the installation groove, and the reaction force of the first spring 104g makes the arc plates 104f clamp and fix the replaced circular ring 104e, so as to realize the placement of bottles of different sizes.

[0037] Example 2

[0038] Reference Figure 4 - Figure 6, which is the second embodiment of the utility model. Different from the above embodiments, this embodiment provides a feeding device, including the above-mentioned sealing mechanism, and also includes a feeding assembly 200, including a support plate 201 fixedly mounted on a fixed frame 103, a guide rail 202 arranged between the support plates 201, and an electric slider 203 slidably mounted on the guide rail 202. The electric slider 203 is a prior art. The electric slider is a common mechanical transmission device, mainly used to achieve linear motion. Its working principle is mainly based on the conversion of the rotational motion of the motor into linear motion through a certain conversion mechanism. The following is the basic working principle of the electric slider: Motor drive: The core of the electric slider is a motor, usually a servo motor or a stepper motor. The rotational motion of the motor is the basis for driving the slider to move; Transmission mechanism: The rotation of the motor is decelerated by a reducer (such as a gear box, belt, chain, etc.) and then transmitted to the slider; the reducer can not only reduce the speed, but also increase the torque, so that the slider can withstand a larger load; Guide rail system: The slider moves along the guide rail system. The guide rail system can be a linear guide, a roller guide or other types of guide rails. The guide rail system ensures that the slider remains stable and accurate during movement; Feedback system: In order to achieve precise control, the electric slider is usually equipped with a position feedback system, such as an encoder or a sensor. These feedback systems can monitor the actual position of the slider and compare it with the control instructions to achieve precise control; Control system: The control system of the electric slider receives instructions from the operator or the automation program, and controls the start, stop and speed of the motor according to these instructions. The control system can also process data from the feedback system and adjust the movement of the motor to ensure that the slider reaches the predetermined position; Safety mechanism: In order to ensure safe operation, the electric slider may also include some safety mechanisms, such as an emergency stop button, overload protection, etc., a lifting member 204 set on the electric slider 203, which drives the clamping member 205 to rise and fall through the lifting member 204, and the clamping member 205 used in conjunction with the lifting member 204, which clamps the product through the clamping member 205, thereby realizing automatic loading, and a material discharge member 206 set on the conveying member 102, through which the sealed product is discharged.

[0039] Specifically, the lifting member 204 includes a mounting plate 204a fixedly mounted on the electric slider 203, an electric push rod 204b symmetrically mounted on the mounting plate 204a, a fixed plate 204c fixedly mounted between the output ends of the two electric push rods 204b, a third motor 204d fixedly mounted on the fixed plate 204c, and a rectangular plate 204e fixedly mounted on the output end of the third motor 204d. Power sources are provided on both sides of the top of the rectangular plate 204e, and the square plate 204f is driven to move toward both sides by the power source, and the square plate 204f is symmetrically and slidably mounted on the rectangular plate 204e.

[0040] Furthermore, the support plate 201 and the guide rail 202 are fixed by screws, the guide rail 202 is arc-shaped, and the third motor 204d does not contact the bottom end of the mounting plate 204a.

[0041] Furthermore, the clamping member 205 includes a clamping plate 205a symmetrically and slidably mounted on the square plate 204f, and the clamping plate 205a has a power source, which is used to drive the clamping plate 205a to move, a placement groove 205b provided on the clamping plate 205a, and a stop block 205c and a second spring 205d arranged in the placement groove 205b. The stop block 205c is driven to reset by the second spring 205d, and after the product is released from the clamp, the stop block 205c no longer contacts other objects, and the second spring 205d may drive the stop block 205c to move repeatedly when resetting. When it moves to the top of a new product, the gap between them can just allow the stop block 205c to move smoothly and no longer reciprocate.

[0042] Furthermore, a semicircular groove is provided on one side of the splint 205a, and the placement groove 205b is located between the semicircular grooves. A rubber pad is provided on the side of the stop block 205c away from the second spring 205d. There are several rubber pads, and the rubber pads play an anti-slip role. A feeding rack for use with the processing table 101 is also provided on one side of the conveying member 102. Unprocessed products are prepared on the feeding rack, and the height of the feeding rack is greater than the processing table 101.

[0043] The rest of the structure is the same as that of Example 1.

[0044] Operation process: After the sealed product is removed through the unloading piece 206, as the turntable 104d rotates, the top ring 104e will lack products. At this time, the electric push rods 204b on both sides are started to drive the fixed plate 204c to descend, so that the rectangular plate 204e drives the clamping piece 205 to descend. When the clamping plate 205a descends, the two clamping plates 205a are driven to move toward the opposite side by the power source, so that the distance between the two clamping plates 205a increases. As the rectangular plate 204e descends, the two clamping plates 205a are At this time, the power source drives the two clamping plates 205a to move toward the opposite sides again, thereby clamping and fixing the two sides of the product. While clamping, the block 205c will also contact the two sides of the product and push the block 205c toward the depth of the placement groove 205b through the product. The reaction force of the second spring 205d enables the block 205c to be close to the surface of the product, and the friction between the block 205c and the product is increased by the rubber pad on its surface to prevent the product from slipping during loading. Then, the electric push rod 204 b drives the clamping member 205 to drive the product to rise. At this time, the electric slider 203 drives the components at the bottom and the clamping member 205 to start moving along the guide rail 202, and then move to the top of the turntable 104d. At this time, the third motor 204d drives the rectangular plate 204e to rotate, and then the power source drives the square plate 204f to move to both sides, so that the clamping member 205 at the bottom drives the product to move, and then matches the two vacant rings 104e, and then the electric push rod 204b drives the clamping member 205 to descend again, and starts again. The power source causes the two sets of clamps 205a to release the clamping of the product, and the product is placed in the empty ring 104e through the clamping member 205, and then the clamping member 205 rises and resets through the electric push rod 204b, and repeats this process to realize automatic loading of the product. After the product is released from the clamping, the stop block 205c no longer contacts other objects, and the second spring 205d may drive the stop block 205c to move repeatedly when resetting. When it moves to the top of the feeding rack, the gap between them allows the stop block 205c to move smoothly and no longer reciprocate.

[0045] Example 3

[0046] Reference Figure 7, which is the third embodiment of the utility model. This embodiment is different from the above embodiments in that the blanking piece 206 includes a screw rod 206a and a second motor 206b arranged on the fixed frame 103, the screw rod 206a is rotatably mounted on the fixed frame 103, a moving block 206c threadedly mounted on the screw rod 206a, an electric telescopic rod 206d symmetrically mounted on the moving block 206c, a lifting plate 206e fixedly mounted between the output ends of the two electric telescopic rods 206d, and an electric clamp 206f arranged on the lifting plate 206e, and the electric clamp 206f is an automated equipment used to automatically clamp, position or fix workpieces during a production process. Its working principle usually involves the following key steps: Power drive: The electric clamp is powered by a power supply (usually an AC or DC power supply) to drive the internal motor or other drive mechanism; Motor control: After the motor inside the clamp receives the control signal, it starts to rotate. The motor can be a servo motor, a stepper motor or a DC motor, etc., which can provide precise control and sufficient power; Transmission mechanism: The rotational motion of the motor is converted into linear motion through gears, belts, screws or other transmission mechanisms, thereby driving the opening and closing of the clamp; Clamping mechanism: The clamping part of the clamp usually consists of two or more movable jaws. When the transmission mechanism drives the jaws to move inward or outward, the workpiece can be clamped or released; Position feedback: In order to achieve precise control, the electric clamp may be equipped with a position sensor or encoder to monitor the position and state of the jaws. This feedback information can be used in a closed-loop control system to ensure the precise operation of the clamp; Control system: The control system of the clamp receives operating instructions such as start, stop, clamp or release, and controls the action of the motor according to these instructions. The control system can be a simple switch logic or a complex PLC (programmable logic controller) or computer control system.

[0047] Specifically, one end of the screw rod 206a is fixedly connected to the output end of the second motor 206b, both ends of the moving block 206c are slidably connected to the top of the fixed frame 103, and there are two electric clamps 206f, both of which are provided with a power source.

[0048] The rest of the structure is the same as that of Example 2.

[0049] Operation process: when unloading the sealed product, the turntable 104d will rotate to the bottom of the electric clamp 206f through the rotation of the turntable 104d. At this time, the two electric telescopic rods 206d synchronously drive the lifting plate 206e to descend. While descending, the two electric clamps 206f clamp the two sides of the two products in turn, and then the two electric telescopic rods 206d drive the lifting plate 206e to rise, so that the electric clamp 206f takes the product out of the ring 104e and rises. At this time, the second motor 206b is started to drive the screw rod 206a to rotate, so that the moving block 206c starts to move, thereby driving the bottom product to move to the top of the conveying member 102, and then the screw rod 206a stops rotating, and the two electric telescopic rods 206d drive the lifting plate 206e to descend again, so that the product falls to the top of the conveying member 102, and the electric clamp 206f releases the clamping of the product, so that the product is transported through the conveying member 102, and then the above steps are repeated to automatically unload and convey the sealed product.
