Description

Technical Field

[0001] The present invention relates to the technical field of woven bag production lines, in particular to a double-layer woven bag one-time forming production line. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic used for packaging. Their raw materials are generally polyethylene, polypropylene, and other chemical plastics. Woven bags are commonly used for packaging. They are generally white or off-white, non-toxic and odorless, and generally pose little harm to the human body. Although made from various chemical plastics, they are highly environmentally friendly and have a high recycling rate. Woven bags have a wide range of uses, primarily for packaging various items, and are widely used in industry.

[0003] After the woven bags are produced and formed, they need to be rolled up and aligned via a conveyor belt. However, when the woven bags are transported on the conveyor belt, they are prone to wrinkles. As a result, during the subsequent alignment process, the woven bags cannot be aligned and may fall over. Therefore, we proposed a double-layer woven bag one-time forming production line.

[0016] Compared with the existing technology, the present invention provides a double-layer woven bag one-time molding production line, which has the following beneficial effects:

[0017] 1. The present invention drives the support frame to move vertically downward when the electric push rod is started, and the support frame drives the connecting frame to move downward, so that the connecting frame drives the fixing rod to move downward. After the fixing rod moves downward, it drives the connecting block on the surface of the insertion rod to contact the woven bag. As the connecting frame continues to move downward, the fixing rod drives the insertion rod and the connecting block to expand outward, so that the wrinkles of the woven bag can be processed when the connecting block moves outward.

[0018] 2. The present invention provides a limit block on the surface of the connecting frame, and a clamping ring inside the connecting frame, and sleeves a connecting ring on the outer surface of the clamping ring, and provides an insertion rod two on the surface of the connecting ring to pass through the connecting frame, thereby preventing the clamping ring from moving horizontally when being squeezed. When the connecting frame is squeezed and bent inward, the clamping ring can slide along the surface of the limit block until the clamping ring is stuck by the limit block, so that the clamping ring does not affect the normal squeezing and smoothing effect of the woven bag.

[0019] 3. The present invention reduces the extrusion on the connecting frame when the electric push rod drives the support frame and the connecting frame to reset, so that the limit block and the clamping ring can cooperate to prevent the connecting frame from suddenly resetting and driving the insertion rod and the connecting block to scratch the woven bag and cause wrinkles.

[0020] 4. The present invention arranges a connecting roller and a fixed rod inside the protective cover, wherein the connecting roller contacts the surface of the fixed rod, so that the fixing rod and the connecting frame can be auxiliary supported by the connecting roller, thereby avoiding the situation where the spring is damaged due to a large tensile force. The connecting roller can be rotated by the fixed rod, thereby ensuring that the connecting roller and the fixed rod will not affect the normal movement of the fixed rod and the connecting frame.

[0021] 5. The present invention can limit the fixed rod by arranging a partition on the outer surface of the connecting roller to ensure that the fixed rod moves in the vertical direction. At the same time, an insertion rod is arranged on the outer surface of the connecting roller so that the connecting block provided at the bottom of the insertion rod contacts the surface of the woven bag, thereby assisting in smoothing the woven bag when the conveyor belt drives the woven bag to move.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0033] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0034] See also Figure 1-8 The present invention provides a technical solution: a double-layer woven bag one-time molding production line, comprising a molding device 1, a leveling device 2 is arranged on the right side of the molding device 1, the leveling device 2 comprises a support frame 21, the outer surface of the support frame 21 is sleeved with a conveyor belt 22, the front of the support frame 21 is fixedly connected to a power component 23, the top of the support frame 21 is fixedly connected to a protective cover 24, a pressing mechanism 25 and a limiting mechanism 26 are arranged inside the protective cover 24, and the pressing mechanism 25 and the limiting mechanism 26 are both arranged above the transmission belt 22.

[0035] The pressing mechanism 25 includes an electric push rod 251, the top of the electric push rod 251 is fixedly connected to the central axis of the top of the inner wall of the protective cover 24, a support frame 254 is provided just below the electric push rod 251, the top of the support frame 254 is fixedly connected to a spring 257, the top of the spring 257 is fixedly connected to the output end of the electric push rod 251, the bottom of the support frame 254 is rotatably connected to a roller 255 through a bearing, a slot 253 is provided at the central axis of the support frame 254, and the outer surface of the electric push rod 251 is fixedly connected to two limit rods 252, the two limit rods 253 are fixedly connected to the outer surface of the electric push rod 251. 52 respectively passes through the two ends of the support frame 254, and a clamping component 256 is provided just below the electric push rod 251. After the woven bag is formed in the forming device 1, it enters the top of the conveyor belt 22, so that the woven bag can be driven to move to the inner center axis of the protective cover 24 by starting the power component 23, so that the electric push rod 251 can be started to drive the support frame 254 to slide vertically along the limit rod 252 through the spring 257 until the support frame 254 drives the roller 255 to move down and contact the woven bag, thereby fixing the woven bag.

[0036] The pressing assembly 256 includes a connecting frame 2561, which passes through the slot 253 and is fixedly connected to the inner wall of the slot 253. A plurality of limit blocks 2565 are fixedly connected to the surface of the connecting frame 2561. One end of the limit block 2565 is tilted upward and the other end is recessed inward. Two fixing rods 2562 are fixedly connected to the bottom of the connecting frame 2561. The inner walls of the two fixing rods 2562 are fixedly plugged with a plug-in rod 2563. Both ends of the two plug-in rods 2563 are provided with connecting blocks 2564. When the rod 251 starts to drive the support frame 254 to move vertically downward, the support frame 254 drives the connecting frame 2561 to move downward, so that the connecting frame 2561 can drive the fixing rod 2562 to move downward. After the fixing rod 2562 moves downward, it drives the connecting block 2564 on the surface of the insertion rod 1 2563 to contact the woven bag. As the connecting frame 2561 continues to move downward, the fixing rod 2562 drives the insertion rod 1 2563 and the connecting block 2564 to expand outward, so that the wrinkles of the woven bag can be processed by the outward movement of the connecting block 2564.

[0037] A snap ring 2566 is provided above the connecting frame 2561, and a connecting ring 2567 is fixedly connected to the outer surface of the snap ring 2566. A second plug rod 2568 is fixedly connected to the outer surface of the connecting ring 2567. The second plug rod 2568 passes through the connecting frame 2561 and extends to the outside of the connecting frame 2561. The outer surface of the snap ring 2566 contacts the recessed portion of the limit block 2565. The horizontal surface of the bottom of the four connecting blocks 2564 is lower than the lowest point of the roller 255, and the four connecting blocks 2564 are rotatably connected to the two plug rods 2563 through bearings. A limit block 2565 is provided, and a snap ring 2566 is provided inside the connecting frame 2561. A connecting ring 2567 is sleeved on the outer surface of the snap ring 2566, and a second insertion rod 2568 is provided on the surface of the connecting ring 2567 so as to penetrate the connecting frame 2561. This prevents the snap ring 2566 from moving horizontally when squeezed. When the connecting frame 2561 is squeezed and bent inwardly, the snap ring 2566 can slide along the surface of the limit block 2565 until the snap ring 2566 is stuck by the limit block 2565, so that the snap ring 2566 does not affect the normal squeezing and smoothing effect of the woven bag.

[0038] When the electric push rod 251 drives the support frame 254 and the connecting frame 2561 to reset, the extrusion on the connecting frame 2561 becomes smaller, so that the cooperation between the limit block 2565 and the clamping ring 2566 can prevent the connecting frame 2561 from suddenly resetting and driving the inserted rod 2563 and the connecting block 2564 to scratch the woven bag and cause wrinkles.

[0039] The limiting mechanism 26 includes a fixed rod 262, and a connecting roller 261 is fixedly connected to the outer surface of the fixed rod 262. Both the positive and negative ends of the fixed rod 262 are rotatably connected to the inner wall of the protective cover 24 through bearings. By arranging the connecting roller 261 and the fixed rod 262 inside the protective cover 24, wherein the connecting roller 261 contacts the surface of the fixed rod 2562, the fixing rod 2562 and the connecting frame 2561 can be auxiliary supported by the connecting roller 161, thereby preventing the spring 257 from being damaged due to a large tension. The connecting roller 261 can be rotated by the fixed rod 262, thereby ensuring that the connecting roller 261 and the fixed rod 262 do not affect the normal movement of the fixing rod 2562 and the connecting frame 2561.

[0040] The outer surface of the connecting roller 261 is in contact with the surface of the fixed rod 2562. The outer surface of the connecting roller 261 is fixedly connected to two partitions 266, and the two partitions 266 are respectively arranged at both ends of the fixed rod 2562. The two partitions 266 are in contact with the surface of the fixed rod 2562. The outer surface of the connecting roller 261 is covered with a connecting sleeve 263. The connecting sleeve 263 is elliptical in shape. A card bead 264 is embedded at the lower end of the connecting sleeve 263. The inner wall of the connecting sleeve 263 is fixedly connected to two limit frames 265. The upper ends of the two limit frames 265 are shaped similar to the connecting sleeve. The shapes of the connecting roller 261 are adapted, and the two limit frames 265 do not contact the outer surface of the connecting roller 261. By arranging a partition 266 on the outer surface of the connecting roller 261, the fixed rod 2562 can be restricted by the partition 266 to ensure that the fixed rod 2562 moves in the vertical direction. At the same time, an insertion rod 263 is arranged on the outer surface of the connecting roller 261 so that the connecting block 264 set at the bottom of the insertion rod 263 contacts the surface of the woven bag, thereby assisting in smoothing the woven bag when the conveyor belt 22 drives the woven bag to move.

[0041] During use, after being formed by the forming device 1, the woven bag enters the upper part of the conveyor belt 22, and the woven bag can be driven to the inner center axis of the protective cover 24 by starting the power component 23, so that the electric push rod 251 can be started to drive the support frame 254 to slide vertically along the limit rod 252 through the spring 257 until the support frame 254 drives the roller 255 to move downward and contact the woven bag, thereby fixing the woven bag;

[0042] When the electric push rod 251 is started and drives the support frame 254 to move vertically downward, the support frame 254 drives the connecting frame 2561 to move downward, so that the connecting frame 2561 drives the fixing rod 2562 to move downward. After the fixing rod 2562 moves downward, it drives the connecting block 2564 on the surface of the insertion rod 1 2563 to contact the woven bag. As the connecting frame 2561 continues to move downward, the fixing rod 2562 drives the insertion rod 1 2563 and the connecting block 2564 to expand outward, so that the wrinkles of the woven bag can be processed by the outward movement of the connecting block 2564.

[0043] By providing a limit block 2565 on the surface of the connecting frame 2561, and providing a snap ring 2566 inside the connecting frame 2561, by sleeve-mounting a connecting ring 2567 on the outer surface of the snap ring 2566, and providing a second insertion rod 2568 on the surface of the connecting ring 2567 so that it penetrates the connecting frame 2561, the snap ring 2566 can be prevented from moving horizontally when being squeezed. When the connecting frame 2561 is squeezed and bent inwardly, the snap ring 2566 can slide along the surface of the limit block 2565 until the snap ring 2566 is stuck by the limit block 2565, so that the snap ring 2566 does not affect the normal squeezing and smoothing effect of the woven bag.

[0044] When the electric push rod 251 drives the support frame 254 and the connecting frame 2561 to reset, the extrusion on the connecting frame 2561 becomes smaller, so that the cooperation between the limit block 2565 and the clamping ring 2566 can prevent the connecting frame 2561 from suddenly resetting and driving the inserted rod 1 2563 and the connecting block 2564 to scratch the woven bag and cause wrinkles.

[0045] By arranging a connecting roller 261 and a fixing rod 262 inside the protective cover 24, wherein the connecting roller 261 contacts the surface of the fixing rod 2562, the fixing rod 2562 and the connecting frame 2561 can be auxiliary supported by the connecting roller 161, thereby preventing the spring 257 from being damaged due to a large tension. The connecting roller 261 can be rotated by the fixing rod 262, thereby ensuring that the connecting roller 261 and the fixing rod 262 do not affect the normal movement of the fixing rod 2562 and the connecting frame 2561.

[0046] By sleeved a partition 266 on the outer surface of the connecting roller 261, the partition 266 can be used to restrict the fixed rod 2562 to ensure that the fixed rod 2562 moves in the vertical direction. At the same time, an insertion rod 263 is sleeved on the outer surface of the connecting roller 261 so that the connecting block 264 set at the bottom of the insertion rod 263 contacts the surface of the woven bag, thereby assisting in smoothing the woven bag when the conveyor belt 22 drives the woven bag to move.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
