A glass panel packing machine

Abstract

This utility model belongs to the field of glass panel packaging, specifically relating to a glass panel packaging machine, including: a packaging machine assembly, comprising a base support mounted on top for support, a first conveyor belt mounted on the surface of the base support, a second conveyor belt mounted on the surface of the base support and aligned front and back with the first conveyor belt, a bottom film roller connected to the side surface of the base support via bearings and located at the bottom side of the first conveyor belt, and a top film roller connected to the side surface of the base support via bearings and located at the top of the first conveyor belt. This utility model utilizes a telescopic rod to extend and drive the sealing seat downwards. When the sealing seat drives the venting pressure plate downwards to press the upper heat-shrink film onto the surface of the glass panel, the venting mechanism effectively squeezes out most of the air between the glass panel and the upper and lower heat-shrink films. This prevents air from remaining inside the package after heat sealing, which could cause bursting during subsequent heat shrinking.

Description

Technical Field

[0001] This utility model belongs to the field of glass panel packaging, and specifically relates to a glass panel packaging machine. Background Technology

[0002] A glass panel is a flat, plate-shaped component made primarily of glass, widely used in modern industry and daily life. Its transparency, flatness, and aesthetic appeal enable it to play a crucial role in numerous fields.

[0003] Glass panel heat shrink film packaging machines are packaging equipment specifically designed for glass panel products. Utilizing the heat-shrink film's shrinkage property, they tightly wrap the glass panel, providing protection, dustproofing, moisture protection, and enhancing the product's appearance. During the transportation, storage, and sales of glass panels, this packaging method reduces the risk of damage caused by collisions, scratches, and other factors.

[0004] Existing heat shrink film packaging machines for glass panels have revealed a significant problem in practical applications: after the sealing process is completed, a certain amount of air often remains inside the film. When the wrapped glass panel is subsequently placed in a heated environment, the heat shrink film begins to shrink due to the heat, and the residual air inside the film expands due to the increased temperature. As the air continues to expand, the pressure it exerts on the heat shrink film gradually increases. Once this pressure exceeds the limit that the heat shrink film can withstand, the heat shrink film will burst. Once the heat shrink film bursts, it will not only damage the original neat packaging appearance, but also directly affect the packaging effect of the glass panel, causing the glass panel to lose the protection that the heat shrink film should provide, increasing the risk of damage during subsequent transportation and storage.

[0005] In view of this, the present invention provides a glass panel packaging machine to solve the problem that gas inside the sealed film can easily cause the packaging film to burst during subsequent heat shrinking. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glass panel packaging machine, comprising:

[0007] The packaging machine assembly includes a base support mounted on top for support, a first conveyor belt mounted on the surface of the base support, a second conveyor belt mounted on the surface of the base support and aligned front and back with the first conveyor belt, a bottom film roller connected to the side surface of the base support by bearings and located on the bottom side of the first conveyor belt, a top film roller connected to the side surface of the base support by bearings and located on the top of the first conveyor belt, and a guide roller connected to the side surface of the base support by bearings.

[0008] The encapsulation assembly includes a support frame connected to the top of the second conveyor belt, a telescopic rod mounted on the surface of the support frame and extending to its bottom, an encapsulation part connected to the movable end of the first telescopic rod, and a guide part connected to the upper surface of the encapsulation part and extending through the interior of the support frame.

[0009] The waste material winding assembly includes a drive unit fitted and mounted on the side surface of the base bracket, a winding roller sleeved on the output end of the drive unit for winding up the waste heat shrink film, and a fixing part connected to the end of the drive unit for fixing the winding roller.

[0010] As a preferred embodiment of the glass panel packaging machine of this utility model, the packaging part includes a packaging seat connected to the movable end of the telescopic rod, an annular heat sealing strip connected to the bottom side of the packaging seat and capable of being electrically heated to achieve heat sealing, an annular cutter disposed on the outer ring of the annular heat sealing strip and connected to the bottom side of the packaging seat, and an exhaust part fitted and installed inside the cavity of the packaging seat.

[0011] As a preferred embodiment of the glass panel packaging machine of this utility model, the exhaust section includes an exhaust pressure plate fitted into the inner wall of the packaging seat and adapted to its cavity size, side ears connected to the inner wall of the exhaust pressure plate and symmetrically arranged, a guide rod penetrating the inside of the side ears and connected to the inner wall of the packaging seat, a limiting block connected to the bottom of the guide rod, and a spring strip connected to the upper surface of the side ears and connected to the inner wall of the packaging seat.

[0012] As a preferred embodiment of the glass panel packaging machine of this utility model, the guide part includes a guide cylinder that penetrates the interior of the support frame and is symmetrically arranged, and a guide rod that penetrates the guide cylinder and is connected to the upper surface of the packaging part.

[0013] As a preferred embodiment of the glass panel packaging machine of this utility model, the driving unit includes a bearing ring fitted and installed on the side surface of the base support, a rotating rod that penetrates the inner wall of the bearing ring and passes through the inside of the take-up roller, a drive motor connected to the end of the rotating rod and installed on the side surface of the base support, and a limiting plate connected to the surface of the rotating rod.

[0014] As a preferred embodiment of the glass panel packaging machine of this utility model, the fixing part includes a fixing plate sleeved on the surface of the guide roller and located at the end of the take-up roller away from the limiting plate, a concave thread connected to the surface of the take-up roller, and a fastening nut sleeved on the surface of the concave thread and threadedly connected thereto.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a telescopic rod to extend and drive the encapsulation base downwards. When the encapsulation base moves downwards and pushes the upper heat-shrink film onto the surface of the glass panel, most of the air between the glass panel and the upper and lower heat-shrink films is squeezed out by the pressure of the pressure plate. The encapsulation base continues to move downwards and heat-seals the upper and lower heat-shrink films using an annular heat-sealing strip. An annular cutter then cuts the outer ring of the heat-sealed area between the upper and lower heat-shrink films. This prevents air from inside the encapsulation package, which could cause it to burst during subsequent heat shrinking. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] This utility model relates to a glass panel packaging machine, such as... Figures 1-6 As shown, it includes:

[0028] The packaging machine assembly 100 includes a base support 101 disposed on top for support, a first conveyor belt 102 mounted on the surface of the base support 101, a second conveyor belt 103 mounted on the surface of the base support 101 and aligned front and back with the first conveyor belt 102, a bottom film roller 104 connected to the side surface of the base support 101 by bearings and located on the bottom side of the first conveyor belt 102, a top film roller 105 connected to the side surface of the base support 101 by bearings and located on the top of the first conveyor belt 102, and a guide roller 106 connected to the side surface of the base support 101 by bearings.

[0029] The encapsulation assembly 200 includes a support frame 201 connected to the top of the second conveyor belt 103, a telescopic rod 202 mounted on the surface of the support frame 201 and extending to its bottom, an encapsulation part 203 connected to the movable end of the first telescopic rod 202, and a guide part 204 connected to the upper surface of the encapsulation part 203 and extending through the interior of the support frame 201.

[0030] It should be noted that the bottom heat shrink film connected to the surface of the bottom film roller 104 passes through the gap between the first conveyor belt 102 and the second conveyor belt 103 via the guide roller 106, and the bottom heat shrink film on the surface of the bottom film roller 104 and the upper heat shrink film on the surface of the top film roller 105 are connected to the surface of the residual material winding assembly 300 via the guide roller 106.

[0031] The encapsulation unit 203 includes an encapsulation base 203a connected to the movable end of the telescopic rod 202, an annular heat-sealing strip 203b connected to the bottom side of the encapsulation base 203a and capable of being heat-sealed by electricity, an annular cutter 203c disposed on the outer ring of the annular heat-sealing strip 203b and connected to the bottom side of the encapsulation base 203a, and an exhaust unit 203d fitted into the cavity of the encapsulation base 203a. When the encapsulation base 203a moves the annular heat-sealing strip 203b downward to the surface of the upper encapsulation film, the heated annular heat-sealing strip 203b can heat-seal the two layers of encapsulation film, while at the same time, the encapsulation film on both sides can be cut by the extrusion of the annular cutter 203c.

[0032] It should be noted that the bottom of the annular cutter 203c and the annular heat seal strip 203b are at the same height.

[0033] Furthermore, the exhaust section 203d includes an exhaust pressure plate 203d-1 fitted into the inner wall of the encapsulation base 203a and adapted to its cavity size, side ears 203d-2 connected to the inner wall of the exhaust pressure plate 203d-1 and symmetrically arranged, a guide rod 203d-3 penetrating the interior of the side ears 203d-2 and connected to the inner wall of the encapsulation base 203a, a limiting block 203d-4 connected to the bottom of the guide rod 203d-3, and a spring strip 203d-5 connected to the upper surface of the side ears 203d-2 and connected to the inner wall of the encapsulation base 203a. When the encapsulation base 203a moves the venting pressure plate 203d-1 downward to the surface of the upper heat shrink film and presses it onto the surface of the glass panel, the encapsulation base 203a continues to move downward, which can cause the guide rod 203d-3 to slide downward inside the side ear 203d-2 and compress the spring strip 203d-5. In this way, the gas between the upper and lower heat shrink films can be discharged through the squeezing of the venting pressure plate 203d-1.

[0034] It should be noted that the bottom of the exhaust pressure plate 203d-1 is lower than the bottom of the annular cutter 203c, and the exhaust pressure plate 203d-1 is made of rubber.

[0035] Furthermore, the guide portion 204 includes a guide cylinder 204a that penetrates the interior of the support frame 201 and is symmetrically arranged, and a guide rod 204b that penetrates the guide cylinder 204a and is connected to the upper surface of the encapsulation portion 203. When the encapsulation base 203a is subjected to an axial force, it can drive the guide rod 204b to slide inside the guide cylinder 204a, which can limit the direction of movement of the encapsulation base 203a and maintain the stability of the encapsulation base 203a during movement.

[0036] In use, the glass panels are first placed sequentially on the surface of the first conveyor belt 102. The glass panels are then conveyed by the first conveyor belt 102. As the glass panels are conveyed from the first conveyor belt 102 to the second conveyor belt 103, they fall onto the surface of the bottom heat-shrink film connected to the bottom film roller 104, and the upper heat-shrink film connected to the surface of the top film roller 105 covers the surface of the glass panels. When the second conveyor belt 103 drives the glass panels to directly below the encapsulation section 203, the telescopic rod 202 can be activated. When the telescopic rod 202 extends, it can drive the encapsulation base 203a to move downward. When the encapsulation base 203a drives the exhaust pressure plate 203d-1 to move downward, it squeezes the upper heat-shrink film. When pressed onto the surface of the glass panel, the air between the glass panel and the upper and lower heat-shrink films is squeezed out by the pressure of the exhaust plate 203d-1. As the sealing base 203a continues to move downward, it can drive the annular heat-sealing strip 203b and the annular cutter 203c to move downward. The annular heat-sealing strip 203b can heat-seal the upper and lower heat-shrink films, while the annular cutter 203c cuts the outer ring of the heat-sealed area of ​​the upper and lower heat-shrink films. Then, the packaged glass panel is conveyed by the second conveyor belt 103 until it is conveyed into the heating equipment, where the upper and lower heat-shrink films are heat-shrinked.

[0039] The drive unit 301 includes a bearing ring 301a fitted onto the side surface of the base bracket 101, a rotating rod 301b penetrating the inner wall of the bearing ring 301a and extending into the inside of the take-up roller 302, a drive motor 301c connected to the end of the rotating rod 301b and mounted on the side surface of the base bracket 101, and a limiting plate 301d connected to the surface of the rotating rod 301b. When the drive motor 301c operates, it can drive the rotating rod 301b to rotate inside the bearing ring 301a. When the rotating rod 301b rotates, it can drive the take-up roller 302 to rotate. When the take-up roller 302 rotates, it can wind up the cut heat-shrink film.

[0040] Furthermore, the fixing part 303 includes a fixing plate 303a sleeved on the surface of the guide roller 106 and located at the end of the take-up roller 302 away from the limiting plate 301d, a concave thread 303b connected to the surface of the take-up roller 302, and a fastening nut 303c sleeved on the surface of the concave thread 303b and threadedly connected to it. After the take-up roller 302 is sleeved on the surface of the rotating rod 301b, the fixing plate 303a is sleeved on the end of the rotating rod 301b, and then the fastening nut 303c is sleeved on the end of the rotating rod 301b and rotates. When the fastening nut 303c rotates on the surface of the rotating rod 301b, it can move laterally through the threaded connection with the concave thread 303b. When the fastening nut 303c moves laterally and presses the fixing plate 303a to the end of the take-up roller 302, the take-up roller 302 can be fixedly installed on the surface of the rotating rod 301b.

[0041] When in use, the drive motor 301c can drive the rotating rod 301b to rotate inside the bearing ring 301a. When the rotating rod 301b rotates, it can drive the take-up roller 302 to rotate. When the take-up roller 302 rotates, it can take up the cut heat shrink film.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
