[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-6As shown in the figure, the present invention provides a lifting-type sealing device, including a frame 1, a U-shaped shell 2 fixed at the middle of the top of the frame 1, a heating mechanism inside the U-shaped shell 2, a second mounting hole at the top of the frame 1, a U-shaped plate 8 inside the second mounting hole, lifting mechanisms for lifting the U-shaped plate 8 at both ends of the bottom of the frame 1, a conveyor belt 10 inside the U-shaped plate 8, and the distance between the conveyor belt 10 and the U-shaped shell 2 can be adjusted by adjusting the height of the U-shaped plate 8, thus conveying glass bottles of different heights. A rotating mechanism for rotating the conveyor belt 10 is provided on the inner side wall of the U-shaped plate 8, and extrusion plates 14 are symmetrically arranged on both sides of the top of the U-shaped plate 8. A gantry frame 6 is fixed at both ends of the top of the frame 1, and a moving mechanism for moving the two extrusion plates 14 is provided on the inner side wall of each of the two gantry frames 6. Sleeves 17 are provided at both ends of the top of each of the two extrusion plates 14, and the inner side walls of the four sleeves 17 slide. The device is connected to four sliders 18, each with a connecting rod 19 fixed to its bottom. The four connecting rods 19 pass through the bottom of four sleeves 17, and one end of each connecting rod 19 is fixed to the top of two extrusion plates 14. Each sleeve 17 contains a spring 20, which is located above the four sliders 18. Through the four sleeves 17, four sliders 18, four connecting rods 19, and four springs 20, the two extrusion plates 14 move up and down with the conveyor belt 10. During use, the height of the U-shaped plate 8 and the conveyor belt 10 can be adjusted by two lifting mechanisms to accommodate glass bottles of different heights, increasing the applicability of the equipment. By moving the two extrusion plates 14 closer together through the moving mechanism, the glass bottles can be clamped and fixed, preventing the glass bottles from tipping over when the conveyor belt 10 stops, and avoiding the possibility of the glass bottles colliding and breaking.

[0025] Specifically, in this embodiment, the rotating mechanism includes two rotating shafts 9, which are rotatably connected to the inner sidewalls at both ends of the U-shaped plate 8. The two ends of the conveyor belt 10 are respectively sleeved on the sidewalls of the two rotating shafts 9. A first mounting hole 4 is provided on one side of the top of the frame 1, and the first mounting hole 4 and the second mounting hole are connected. The first mounting hole 4 and the second mounting hole are connected, which allows the first motor 5 to move together with the U-shaped plate 8. The first motor 5 is installed inside the first mounting hole 4, and the first motor 5 and the U-shaped plate 8 are fixed. The output shaft of the first motor 5 is fixed to one end of one of the rotating shafts 9, driving the first motor 5 to drive one of the rotating shafts 9 to rotate slowly, which in turn drives the other rotating shaft 9 to rotate the conveyor belt 10 slowly, thereby conveying the glass bottles.

[0026] Specifically, in this embodiment, the lifting mechanism includes an L-shaped plate 3, which is fixed to the middle of one side of the bottom of the frame 1. An electric telescopic rod 11 is fixed inside the bottom of the L-shaped plate 3, and the output end of the electric telescopic rod 11 is fixed to the bottom of the U-shaped plate 8. Driving the two electric telescopic rods 11 drives the U-shaped plate 8 to move upward, thereby driving the conveyor belt 10 to move upward. This allows the distance between the conveyor belt 10 and the U-shaped shell 2 to be adjusted, thus enabling the conveying of glass bottles of different heights.

[0027] Specifically, in this embodiment, the moving mechanism includes a bidirectional lead screw 12, which is rotatably connected to the inner wall of one of the gantry frames 6, and one end of the bidirectional lead screw 12 passes through the outer wall of one of the gantry frames 6. Lead screw nuts 13 are symmetrically fitted at both ends of the side wall of the bidirectional lead screw 12, and both lead screw nuts 13 are adapted to the bidirectional lead screw 12. The two lead screw nuts 13 are respectively fixed to the top of two sleeves 17. A second motor 7 is fixed to the outer wall of one of the gantry frames 6, and the output shaft of the second motor 7 is fixed to the other end of the bidirectional lead screw 12. Synchronous pulleys 15 are fitted to one end of each of the two bidirectional lead screws 12. A synchronous belt 16 is provided at the top of the frame 1. The timing belt 16 and the two timing pulleys 15 allow the two bidirectional lead screws 12 to rotate simultaneously, preventing a speed difference between the two bidirectional lead screws 12 that could cause the two ends of the extrusion plate 14 to move asynchronously and jam. The two ends of the timing belt 16 are respectively sleeved on the inner sidewalls of the two timing pulleys 15, driving the second motor 7 to rotate one of the bidirectional lead screws 12. This, in conjunction with the timing belt 16 and the two timing pulleys 15, drives the other bidirectional lead screw 12 to rotate. The simultaneous rotation of the two bidirectional lead screws 12 causes the four lead screw nuts 13 to move closer together in pairs. This, in conjunction with the four sleeves 17 and the four connecting rods 19, causes the two extrusion plates 14 to move closer together, clamping and fixing the glass bottle.

[0028] Specifically, in this embodiment, the heating mechanism includes multiple electric heating tubes 21, which are fixed in a U-shape at equal intervals on the inner wall of the U-shaped shell 2. After the multiple electric heating tubes 21 are powered on, their surface temperature rises rapidly, causing the plastic film covering the glass bottle to undergo thermal shrinkage, thereby completing the sealing process.

[0029] Working Principle: During operation, this device uses an external conveyor to place multiple glass bottles, each covered with plastic film and at the same height, at equal intervals on top of the conveyor belt 10. The power switch of the first motor 5 is then turned on, driving one of the rotating shafts 9 to rotate slowly. This, in turn, drives the conveyor belt 10 to rotate slowly. When some of the plastic-film-covered glass bottles reach the bottom of the U-shaped shell 2, the power switch of the second motor 7 is turned on, driving one of the bidirectional lead screws 12 to rotate. This, in turn, drives the other bidirectional lead screw 12 to rotate, in conjunction with the synchronous belt 16 and two synchronous pulleys 15. Both bidirectional lead screws 12 rotate simultaneously. The four lead screw nuts 13 are driven to move closer together in pairs, which, together with the four sleeves 17 and four connecting rods 19, causes the two extrusion plates 14 to move closer together, clamping and fixing the glass bottle. After fixing, the power switch of the first motor 5 is turned off, and the conveyor belt 10 stops rotating and no longer conveys the glass bottle. At this time, the glass bottle is in a fixed state. At the moment the conveyor belt 10 stops, a momentary speed difference will occur between the conveyor belt 10 and the glass bottle, causing the glass bottle to tip over and collide with each other, which improves the practicality of this device. When the conveying stops, the second motor 7 drives the bidirectional lead screw 12 to rotate in the opposite direction, thereby causing the two extrusion plates 14 to move away from each other. The glass bottle is released from its fixed position. Simultaneously, the power switches of multiple electric heating elements 21 are turned on. After the heating elements 21 are energized, their surface temperature rises rapidly, causing the plastic film covering the glass bottle to shrink thermally, thus completing the sealing process. After sealing, the power switch of the first motor 5 is turned on again, causing the conveyor belt 10 to continue rotating and conveying the sealed glass bottle out of the U-shaped shell 2. The remaining unsealed glass bottles are conveyed into the U-shaped shell 2 and transferred to other positions using external clamping equipment for the next process. This process is repeated until all sealing is completed. When glass bottles of different heights need to be transported, the power switches of the two electric telescopic rods 11 are turned on, driving the two electric telescopic rods 11 to move the U-shaped plate 8 upward, which in turn moves the conveyor belt 10 upward until the U-shaped plate 8 is raised to the designated position. When the U-shaped plate 8 moves upward, it drives the two extrusion plates 14 to move upward at the same time. With the help of the four sliders 18 and the four connecting rods 19, the four springs 20 are compressed. Under the reaction action of the four compressed springs 20, the bottom of the two extrusion plates 14 and the surface of the conveyor belt 10 are always in contact. During the process, no manual adjustment is required, saving time and improving work efficiency.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
