Description

Technical Field

[0001] The invention relates to the technical field related to blister packaging equipment, in particular to a blister hot pressing device which is convenient for loading materials. Background Art

[0002] Blister packaging is a common packaging method. It mainly uses the hot pressing process to heat and soften the plastic hard sheet, and then adsorb it on the surface of the product or cardboard and other supporting materials through a mold and pressure to form an integral package. This packaging method can make the product clearly visible and can provide physical protection for the product to prevent the product from being damaged by external squeezing or collision.

[0003] A Chinese patent with announcement number CN220946635U discloses a blister packaging hot pressing device, which belongs to the hot pressing field and includes an equipment base, an equipment frame is installed on the equipment base, a rotating mechanism is installed on the equipment base, a hot pressing rotating platform is installed on the rotating mechanism, and a plurality of hot pressing lower die seats are installed on the top side of the hot pressing rotating platform. The plurality of hot pressing lower die seats are arranged in a circular array. During the hot pressing process of the blister packaging product, the blister packaging product to be hot pressed is placed on the hot pressing lower die seat, the hot pressing mechanism is started, the hot pressing upper die is driven to move downward, and the blister packaging product below is hot pressed. During the hot pressing process, due to the different thickness and specifications of the blister packaging, the downward movement of the hydraulic cylinder is controlled by the control panel, and the rotating handle is rotated at the same time to drive the threaded column to rotate, thereby driving the height position of the position baffle. By adjusting the position baffle, the lowest position of the downward movement of the mounting plate can be set, thereby playing a protective role.

[0004] In summary, the above patent adopts the combination of telescopic cylinder and vacuum suction cup, and after the hot pressing of the packaged product is completed, the packaged product can be sucked away for unloading and transfer. However, since the plastic sheet has not been completely cooled and solidified after being hot pressed onto the cardboard, the adhesion between the plastic sheet and the cardboard has not reached the best. In addition, when packaging heavier products, the method of unloading and transferring by suction cup adsorption can easily cause the plastic and cardboard to deform under the action of external force, which can easily cause the plastic sheet to separate from the cardboard, resulting in product falling or an increase in defective packaging products, which in turn affects the subsequent loading of products and the efficiency of operations by subsequent staff. Summary of the invention

[0005] The object of the present invention is to provide a thermoforming hot pressing device which is convenient for loading materials, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a thermoforming hot pressing device convenient for loading materials, comprising a frame,

[0011] A groove is provided on the top of the frame, and a feeding mechanism is arranged in the groove.

[0012] Preferably, a rotating seat is fixed on the top of the frame, and the output end of the rotating seat is connected to the turntable.

[0013] In the above technical solution, the rotating seat can drive the turntable to rotate.

[0014] Preferably, the ejection mechanism includes an ejector pin, which is installed inside the mold and penetrates the turntable. A mounting plate is fixed to the bottom of the ejector pin, and a sphere is fixed to the bottom of the mounting plate. The top of the mounting plate is connected to the turntable through a spring, and a wedge block is fixed to the top of the frame.

[0015] In the above technical scheme, when the hot-pressed mold and the packaged product are rotated to be aligned with the grooves on the frame, the ball at the bottom of the mounting plate will resist the wedge block, and will drive the mounting plate and the ejector to move upward under the action of the wedge block, so that the ejector can push the hot-pressed packaged product upward out of the mold for unloading. After unloading, as the turntable rotates, the ball will move and separate from the wedge block. At this time, the spring will drive the mounting plate and the ejector to descend and reset.

[0018] In the above technical solution, the motor drives the screw rod to rotate, so that the screw rod can drive the movable block threadedly connected to it to move horizontally, thereby driving the U-shaped plate and the lifting rod to move horizontally. The hydraulic cylinder can drive the U-shaped plate and the lifting rod to move vertically, so as to drive the packaged product to be lifted and lowered.

[0019] Preferably, the adjustment mechanism includes motor 2, which is fixed to the outside of the U-shaped plate, and the output end of motor 2 is connected to screw rod 2, which is installed on the inside of the U-shaped plate, and screw rod 2 passes through the lifting rod and is threadedly connected to it.

[0020] In the above technical solution, the second motor drives the second screw rod to rotate, so that the second screw rod can drive the two groups of lifting rods threadedly connected thereto to move closer to or away from each other, so that the lifting rods can be used to adapt to packaging products of different specifications and sizes.

[0021] Preferably, the feeding mechanism comprises a conveyor belt, the conveyor belt is installed in the groove, and guide plates are fixed at both ends of the outer side of the L-shaped fixing frame.

[0022] In the above technical solution, the conveyor belt can convey and transfer the packaged products after unloading, and the guide plate can limit the two sides of the packaged products to avoid deviation and falling off during the conveying process.

[0023] Compared with the prior art, the invention has the following beneficial effects: the thermoforming hot pressing device which is convenient for loading materials,

[0024] (1) During use, when the hot-pressed mold and the packaged product rotate to align with the groove on the frame, the packaged product is in the unloading area, and the ejection mechanism automatically ejects the packaged product in the mold upwards. Then, the lifting rod can be driven by the transverse movement mechanism to move to the bottom of the plastic part to lift the plastic part and the product. Since the hot-pressed plastic part is located at the bottom and the paperboard is located at the top, the entire packaged product can be lifted and transferred. Therefore, the packaged product will not be deformed or the plastic part will not be separated from the paperboard due to external force. The defective rate of products caused during the unloading process can be greatly reduced, which helps to improve the feeding efficiency during continuous operation. It is also suitable for the packaging transfer of heavier products and has a wide range of uses.

[0025] (2) By driving the second screw rod to rotate through the second motor, the second screw rod can drive the two groups of lifting rods threadedly connected to it to move closer to or farther away from each other, so that the lifting rods can be used to adapt to the packaging products of different specifications and sizes. In the unloading process, the two groups of lifting rods can be brought closer to each other to clamp and unload the packaging products according to the usage conditions. This technical solution can adaptively adjust the function of the lifting rod according to the usage conditions to improve its functionality. BRIEF DESCRIPTION OF THE DRAWINGS
