Description

Technical Field

[0001] This utility model belongs to the field of woven bag production and processing technology, and in particular relates to a sealing device for woven bag production and processing. Background Technology

[0002] Woven bags are typically made of materials such as polypropylene. While their woven structure has a certain strength, the edges are relatively loose. Edge sealing secures these loose edge fibers or threads, preventing the edges of the woven bag from easily coming undone or fraying. This greatly enhances the overall strength of the woven bag. When containing and transporting various items, especially heavy or irregularly shaped items, woven bags can better withstand pressure and friction, and are less prone to leakage or premature damage due to edge breakage, effectively ensuring the reliability of the woven bag during use.

[0003] Existing edge-sealing devices for woven bag production and processing can only seal one side of the woven bag, which limits the efficiency of the edge-sealing operation and thus affects the edge-sealing speed. Utility Model Content

[0033] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0034] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Please see Figures 1 to 5 This utility model provides a sealing device for woven bag production and processing, including a first support frame 1, a second support frame 2 mounted on the top of the first support frame 1, two symmetrical first rotating shafts 3 mounted on the first support frame 1, a first driving wheel 4 and a first driven wheel 5 respectively mounted on the first rotating shafts 3; a first conveyor belt 6 mounted on the first driving wheel 4 and the first driven wheel 5; a top rod 7 slidably connected to the second support frame 2, and a housing 8 mounted on the other end of the top rod 7; a first spring 9 sleeved on the outer surface of the top rod 7, with both ends of the first spring 9 connected to the second support frame 2 and the housing 8 respectively; two symmetrical second rotating shafts 10 rotatably connected inside the housing 8, a second driving wheel 11 and a second driven wheel 12 respectively mounted on the second rotating shafts 10; a second conveyor belt 13 mounted on the first driving wheel 4 and the second driven wheel 12; and a sealing assembly mounted on the first support frame 1.

[0036] Furthermore, a first motor 14 is installed on the housing 8; the output end of the first motor 14 is connected to one of the second rotating shafts 10, and the two ends of the other second rotating shaft 10 are equipped with first synchronous pulleys 15; the two ends of the first rotating shaft 3 are equipped with second synchronous pulleys 16 aligned with the first synchronous pulleys 15, and a first synchronous belt 17 is sleeved on the first synchronous pulleys 15 and the second synchronous pulleys 16.

[0037] Using the above scheme: In use, the operator lifts the housing 8, causing the housing 8 to move the top rod 7 upward and compress the first spring 9, thereby adjusting the distance between the first conveyor belt 6 and the second conveyor belt 13 to accommodate woven bags of different thicknesses. Subsequently, the woven bag is placed on the first conveyor belt 6, with the edges of the woven bag aligned with the sealing assembly. After starting the first motor 14, the second rotating shaft 10 rotates synchronously, thereby causing the second conveyor belt 13 to rotate due to the rotation of the second driving wheel 11 and the second driven wheel 12. During this process, when one of the second rotating shafts 10 rotates, it drives the first synchronous wheel 15 to rotate. The first synchronous wheel 15 rotates the second synchronous wheel 16 through the first synchronous belt 17, thereby causing the first rotating shaft 3 to rotate. With the assistance of the first driving wheel 4 and the first driven wheel 5, the first conveyor belt 6 rotates. With the coordinated work of the first conveyor belt 6 and the second conveyor belt 13, the woven bag is transported to the position of the sealing assembly, and then the edge sealing assembly is used to seal the edges of the woven bag.

[0038] Furthermore, the edge sealing assembly includes a first fixing plate 18 fixedly connected to the two side walls of the first support frame 1; a first slider 19 is slidably connected to the two first fixing plates 18, and a third rotating shaft 20 is rotatably connected to the first slider 19; a rolling sheet 21 is installed at one end of the third rotating shaft 20, and a second motor 26 is installed on one side of the first slider 19, with the output end of the second motor 26 connected to the third rotating shaft 20.

[0039] Furthermore, the first fixing plate 18 has a plurality of first fixing holes; the first slider 19 has a second fixing hole aligned with the first fixing holes, and a fixing rod 22 is installed in the second fixing hole; the other end of the fixing rod 22 extends into the first fixing hole.

[0040] The above solution is used as follows: In use, the first slider 19 is moved up and down on the first fixed plate 18, so that the rolling plate 21 can contact the upper surface of the woven bag. After the rolling plate 21 is adjusted, the fixing rod 22 is inserted into the first fixing hole and the second fixing hole to fix the first slider 19. When the woven bag gradually contacts the rolling plate 21 under the drive of the first conveyor belt 6 and the second conveyor belt 13, the output end of the second motor 26 rotates, which in turn drives the third rotating shaft 20 to rotate. When the third rotating shaft 20 rotates, it will drive the rolling plate 21 to rotate, thereby sealing the edge of the woven bag.

[0041] It should be noted that: before the roller pressing plate 21 seals the woven bag, the roller pressing plate 21 can be heated by a heater to seal the woven bag.

[0042] Furthermore, a second slider 23 is slidably connected to the side wall of the second support frame 2; a first rolling wheel 24 and a second rolling wheel 25 are rotatably connected to the second slider 23, and the first rolling wheel 24 and the second rolling wheel 25 are respectively located on both sides of the rolling sheet 21; a first connecting rod 27 is installed on the housing 8, and the other end of the first connecting rod 27 is fixedly connected to the second slider 23.

[0043] Furthermore, a third synchronous wheel 28 is installed on the side of the first rotating shaft 3 away from the second synchronous wheel 16; a fourth synchronous wheel 29 is installed on one end of the first rolling wheel 24 and is aligned with the third synchronous wheel 28, and a second synchronous belt 30 is sleeved on the third synchronous wheel 28 and the fourth synchronous wheel 29.

[0044] Furthermore, a proximity sensor 31 is installed on one side of the first rolling wheel 24; a control panel 32 is installed on the second support frame 2, the proximity sensor 31 is signal-connected to the control panel 32, and both the first motor 14 and the second motor 26 are signal-connected to the control panel 32.

[0045] Using the above scheme: In use, after the housing 8 moves to the preset position, the second slider 23 is moved by the first connecting rod 27, causing the first crushing roller 24 and the second crushing roller 25 to move to the corresponding positions. As the first rotating shaft 3 rotates, the third synchronous wheel 28 causes the fourth synchronous wheel 29 to rotate via the second synchronous belt 30. The rotation of the fourth synchronous wheel 29 further drives the first crushing roller 24 to rotate. After the tail of the woven bag is sealed by the rolling plate 21, it gradually contacts the first crushing roller 24 under the conveying of the first conveyor belt 6 and the second conveyor belt 13. 4. Eliminate air bubbles left after sealing the tail of the woven bag. When the tail of the woven bag moves to the preset position, the proximity sensor 31 detects it and then sends a signal to the control panel 32. The control panel 32 then instructs the first motor 14 to rotate in the opposite direction and the second motor 26 to stop rotating, so that the woven bag moves in the opposite direction and approaches the second rolling wheel 25. The second rolling wheel 25 rotates passively under the action of the friction of the woven bag, providing auxiliary pressure and achieving flexible bonding of the entire edge of the woven bag. At the same time, it works together with the first rolling wheel 24 to effectively deal with the air bubbles generated during the sealing of the edge of the woven bag.

[0046] The working principle of this utility model:

[0047] By sliding the first slider 19 up and down on the first fixed plate 18, the rolling plate 21 can contact the upper surface of the woven bag. After the rolling plate 21 is adjusted, the fixing rod 22 is inserted into the first fixing hole and the second fixing hole to fix the first slider 19. Then, the worker lifts the housing 8, which causes the top rod 7 to move upward and compress the first spring 9, thereby adjusting the distance between the first conveyor belt 6 and the second conveyor belt 13 to accommodate woven bags of different thicknesses. Subsequently, the woven bag is placed on the first conveyor belt 6, with the two side edges of the woven bag aligned with the sealing assembly. After starting the first motor 14, the second rotating shaft 10 rotates synchronously, thereby moving the second drive wheel 11. The rotation of the second driven wheel 12 causes the second conveyor belt 13 to rotate. During this process, when one of the second rotating shafts 10 rotates, it drives the first synchronous wheel 15 to rotate. The first synchronous wheel 15 drives the second synchronous wheel 16 to rotate through the first synchronous belt 17, thereby causing the first rotating shaft 3 to rotate. With the assistance of the first driving wheel 4 and the first driven wheel 5, the first conveyor belt 6 rotates. When the woven bag gradually contacts the rolling plate 21 under the drive of the first conveyor belt 6 and the second conveyor belt 13, it rotates through the output end of the second motor 26, which in turn drives the third rotating shaft 20 to rotate. When the third rotating shaft 20 rotates, it drives the rolling plate 21 to rotate, thereby sealing the edge of the woven bag.
