Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a transportation device that prevents strip-shaped objects from accumulating and falling out. Background Technology

[0002] In the beverage and other liquid food packaging industry, adhesive strips are commonly used during the sealing process to seal the openings or seams of paper-plastic composite boxes, ensuring that the beverage boxes have good airtightness, leak-proofness, and freshness preservation performance. To achieve high-efficiency and continuous production, packaging production lines are usually equipped with adhesive strip supply and transmission mechanisms to transport the adhesive strips from the storage end to the bonding or sealing station.

[0003] However, during the startup and automatic splicing process when the adhesive strip is fully wound, the initial rotation from static to dynamic is at a fixed speed. Ideally, this ensures that the roll outputs a fixed length of adhesive strip and delivers it to the next unit at a fixed speed. However, the diameter of the adhesive strip roll is not standard; some rolls are too large. This results in excessive (long) adhesive strips being output at the same rotation speed, causing the strips to accumulate momentarily in front of the guide wheel. This can easily lead to the strips jumping off the guide wheel, causing equipment malfunction and posing significant product quality and safety hazards. Utility Model Content

[0020] Please refer to Figures 1-4This utility model provides a transport device to prevent strip-shaped objects from accumulating and falling out, including: a mounting panel 100 and a transport assembly. The transport assembly includes: a first reel 110, which is disposed on one side of the mounting panel 100 and used to accommodate the main strip-shaped object 230; and a first guide device, including a first guide wheel 122 and a first extension plate 121 disposed on the top of the mounting panel 100, with the first guide wheel 122 mounted on the first extension plate 121. Further, the mounting panel 100 refers to a plate-like structure used to support and fix the transport assembly, specifically made of metal sheet or high-strength engineering plastic. Its function is to provide a stable mounting base for the reel and the guide device, preventing the assembly from shifting due to vibration during transport. The first reel 110 is a rotating component used to carry the main strip-shaped object 230, specifically made of a detachable reel structure with a shaft core. Its function is to release the main strip-shaped object 230 by rotation. The first guiding device refers to the mechanism that guides the transmission direction of the main strip 230, specifically including a first guide wheel 122 and a first extension plate 121. The first guide wheel 122 adjusts the direction of the strip through rolling contact, and the first extension plate 121 provides suspension support for the guide wheel. The two work together to prevent the strip from deviating from the predetermined path. The first guide wheel 122 is a pulley structure with annular grooves on its surface, which can be implemented by combining bearings and a metal wheel body. The grooves limit the lateral displacement of the strip, preventing it from coming off during high-speed transmission. The first extension plate 121 is a plate-shaped support extending outward from the top of the mounting panel 100, which can be implemented by using a metal plate integrally formed with the mounting panel 100. Its function is to lift the guide wheel above the reel, forming a height difference to control the tension of the strip.

[0021] In this embodiment, the first guide wheel 122 is positioned above the first reel 110, and a second guide wheel 130 is positioned between the first guide wheel 122 and the first reel 110. The main strip 230 on the first reel 110 is wound around the right side of the second guide wheel 130 and then around to the left side of the first guide wheel 122. Furthermore, when the main strip 230 is released from the first reel 110, it first rises in conveying height along the curved surface on the right side of the second guide wheel 130, adjusting the tension of the strip through the frictional resistance generated by the contact arc surface. Subsequently, the strip extends upward at an inclined angle to the left side of the first guide wheel 122, forming an "S"-shaped zigzag path. This path creates two controlled straight segments in the vertical direction, with the second guide wheel 130 serving as the initial tension buffer.

[0022] In this embodiment, the transport component includes a third guide wheel 140, which is disposed to the right of the first guide wheel 122. The main strip 230 extends from the left side of the first guide wheel 122 to the right side of the third guide wheel 140. Furthermore, the third guide wheel 140 and the first guide wheel 122 are not arranged at horizontal intervals, forming a secondary turning path for the main strip 230 between them.

[0023] In this embodiment, the transport assembly includes a second reel 150, which is disposed on one side of the mounting panel 100 and is used to accommodate the secondary strip 240. The second guiding device includes a fourth guide wheel 162 and a second extension plate 161 disposed on the top of the mounting panel 100. The fourth guide wheel 162 is disposed on the second extension plate 161. The fourth guide wheel 162 is disposed above the second reel 150. A fifth guide wheel 170 is disposed between the fourth guide wheel 162 and the second reel 150. A secondary strip 240 on the second reel 150 is wound around the left side of the second guide wheel 130 and then around to the right side of the fourth guide wheel 162. Further, the second reel 150 is fixedly connected to the side of the mounting panel 100. The second extension plate 161 extends horizontally outward from the top of the mounting panel 100 to form a cantilever structure. The fourth guide wheel 162 is mounted at the end of the second extension plate 161 via a pivot. The fifth guide wheel 170 is located between the second reel 150 and the fourth guide wheel 162, and its installation height is lower than the fourth guide wheel 162 and higher than the top of the second reel 150. After being drawn out from the second reel 150, the secondary strip 240 winds counterclockwise around the left rim of the fifth guide wheel 170, and then extends upward to the right rim of the fourth guide wheel 162. The lengths of the first extension plate and the second extension plate are 15cm to 25cm.

[0024] In this embodiment, a connecting assembly is included. The connecting assembly includes a first connecting block 191 and a second connecting block 192 disposed opposite to the first connecting block 191. A guide groove 193 is provided on the top of the first connecting block 191, and a guide rod 194 is provided above the guide groove 193. The secondary strip 240 is guided from the guide rod 194 to the side of the guide groove 193 near the second connecting block 192. Further, the first connecting block 191 and the second connecting block 192 form a positioning structure arranged opposite to each other. The guide groove 193 is opened in a specific area on the top of the first connecting block 191. The guide rod 194 is fixed obliquely above the guide groove 193. The secondary strip 240 extends downward from the surface of the guide rod 194 into the guide groove 193. A limiting wall is formed on the edge of the guide groove 193 near the second connecting block 192. The secondary strip 240 enters the gap between the first connecting block 191 and the second connecting block 192 along the extending direction of the limiting wall. The width of the guide groove 193 is slightly greater than the thickness of the main strip 230.

[0025] In this embodiment, a sixth guide wheel 180 is included. The sixth guide wheel 180 is disposed above the first connecting block 191 and the second connecting block 192 to guide the main strip 230 through the space between the first connecting block 191 and the second connecting block 192. Furthermore, the sixth guide wheel 180 contacts the main strip 230 through its wheel surface, and the wheel axis is perpendicular to the extension direction of the connecting block. The installation height of the sixth guide wheel 180 is higher than the guide groove 193 of the first connecting block 191, so that the main strip 230 forms a downward-sloping conveying path when passing between the connecting blocks. An annular groove is provided on the wheel surface, and the groove width matches the width of the main strip 230. A straight conveying path is formed between the sixth guide wheel 180 and the third guide wheel 140 of the first roller 110, preventing the main strip 230 from twisting during conveying.

[0026] In this embodiment, the second connecting block 192 includes a heating connecting component 196, which is used to heat and weld the main strip 230 and the secondary strip 240 after pressing them together. Furthermore, the heating welding component 197 employs a resistance heating element, ensuring that the adhesive strip material softens upon heating but does not carbonize.

[0027] In this embodiment, the second connecting block 192 includes the heating and fusing component 197, which is disposed above the heating connecting component 196 and is used to fuse the main strip 230. Further, the heating and fusing component 197 and the heating connecting component 196 form a layered structure in the vertical direction, with the heating and fusing component 197 located in the top region of the heating connecting component 196. After the main strip 230 is positioned by the guide groove 193 and the guide rod 194, it extends to the second connecting block 192. After the heating connecting component 196 completes the pressing and welding of the main strip 230 and the secondary strip 240, the heating and fusing component 197 applies heat energy to the main strip 230 above the welding point to fuse the main strip 230.

[0028] In this embodiment, an upper buffer wheel assembly 198 is provided on the mounting panel 100, and a connecting plate 199 is provided at the bottom of the mounting panel 100. A mounting block 200 is provided at the end of the connecting plate 199 away from the mounting panel 100, and a lower buffer wheel assembly 210 corresponding to the upper buffer wheel assembly 198 is provided on the mounting block 200. The upper and lower buffer wheel assemblies 210 are arranged correspondingly to each other to form a clamping direction for the strip, so that the strip forms a bypass path between the upper and lower wheels, thereby absorbing the tension fluctuations generated during transportation and avoiding breakage or displacement of the strip due to excessive instantaneous tension.

[0029] In this embodiment, both the main strip 230 and the secondary strip 240 are adhesive strips. In some embodiments, a drive device 220 is included, which drives the first reel 110 and the second reel 150 to rotate. Further, the drive device 220 may include an independent motor or a linkage transmission mechanism, connected to the first reel 110 and the second reel 150 respectively, controlling the output speed of the adhesive strip by adjusting the rotation speed. The adhesive strip is made of a hot-melt material, and its width and thickness match the guide wheel groove structure. The drive device 220 may integrate a feedback control module to dynamically adjust the reel rotation speed based on tension sensor signals in the adhesive strip conveying path.
