Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing machinery, in particular to a woven bag production cutting machine. Background Art

[0002] Woven bags are a type of plastic used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Plastic woven bags are made of polypropylene resin as the main raw material, which is extruded and stretched into flat yarn, and then woven and made into bags.

[0003] Currently, woven bag production requires the use of a cutting machine to slit the bags. Traditional cutting machines typically rely on a simple conveyor system to transport the bags. During this process, the bags can easily shift due to various reasons. For example, conveyor instability or even slight external interference can cause the bags to deviate from the intended cutting path, significantly reducing cutting accuracy. Therefore, we propose a woven bag production cutting machine to address these issues. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology and to propose a woven bag production cutting machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, an anti-wrinkle mechanism is provided on the fixed frame, and the anti-wrinkle mechanism includes two fixed plates fixed on the fixed frame, and two rollers are rotatably connected between the two fixed plates. The two rollers are connected by a long and wide conveyor belt transmission, and spur gears are sleeved on the outer side walls of the rollers and the conveying shaft, and the two spur gears are meshed and connected.

[0009] Preferably, chain plates matching the chains are sleeved on the outer side walls of two adjacent conveying shafts.

[0010] Preferably, the distance between two adjacent correction wheels on the same side is the same, and the two adjacent correction wheels are symmetrically arranged on both sides of the transmission shaft.

[0013] Preferably, the distance between two adjacent conveying shafts is the same, and the tops of the plurality of conveying shafts are located on the same plane.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 A woven bag production cutting machine includes a fixed frame 1 and a lifting cutting machine body 2. The lifting cutting machine body 2 is fixed on the fixed frame 1. Multiple transmission shafts 3 are rotated on the fixed frame 1. A transmission sleeve 4 is fixedly sleeved on the transmission shaft 3. Two adjacent transmission shafts 3 are connected by a chain 5. A motor 6 is fixed on the fixed frame 1. The output shaft of the motor 6 is fixedly connected to the end of one of the transmission shafts 3.

[0023] To further illustrate, the lifting and cutting machine body 2 can cut the woven bag on the conveying sleeve 4 after being started. The lifting and cutting machine body 2 and the motor 6 are both commonly used means in the prior art and will not be described in detail here.

[0024] Chain plates matching the chains 5 are sleeved on the outer side walls of two adjacent conveying shafts 3 .

[0025] It is further explained that the transmission connection is made through the chain 5 so that when the motor 6 drives one of the transmission shafts 3 to rotate, it can also drive the other transmission shafts 3 to rotate synchronously, thereby ensuring the stable transmission of the woven bags.

[0026] like Figure 2 As shown, the distance between two adjacent conveying shafts 3 is the same, and the tops of the multiple conveying shafts 3 are located on the same plane.

[0027] It is further explained that the purpose of this setting is to ensure that the woven bag is evenly stressed during the transmission process and moves forward smoothly, providing a good foundation for subsequent cutting work.

[0028] like Figure 1 and Figure 2 As shown, a correction mechanism is provided in the fixed frame 1; the correction mechanism includes a plurality of L-shaped plates 7 fixed to the inner wall of the fixed frame 1, and a common rotating shaft 8 rotates between two L-shaped plates 7 on the same side, and one of the transmission shafts 3 and the two rotating shafts 8 are fixedly sleeved with staggered axis bevel gears 9, and two adjacent staggered axis bevel gears 9 are meshed and connected, and a plurality of correction wheels 10 are fixedly sleeved on the rotating shaft 8, and the top of the transmission sleeve 4 is flush with the top of the correction wheel 10.

[0029] It is further explained that by setting up multiple L-shaped plates, rotating shafts 8 and staggered axis bevel gears 9, one of the transmission shafts 3 can drive the two rotating shafts 8 to rotate, and then drive the correction wheel 10 on the rotating shaft 8 to rotate. When the woven bag is transmitted on the transmission sleeve 4, the correction wheel 10 can correct the woven bag laterally to ensure that the surface of the woven bag remains in a straight line during the transmission process, thereby improving the cutting accuracy of the lifting cutting machine body 2.

[0030] like Figure 2 As shown, the conveying shaft 3 and the rotating shaft 8 are arranged vertically and staggered.

[0031] It is further explained that the transmission shaft 3 and the rotating shaft 8 are staggered and vertically arranged, which rationally utilizes the space, makes the equipment structure more compact, and ensures that the correction mechanism can effectively correct the woven bag.

[0032] like Figure 2 and Figure 3 As shown, the distance between two adjacent straightening wheels 10 on the same side is the same, and the two adjacent straightening wheels 10 are symmetrically arranged on both sides of the conveying shaft 3.

[0033] It is further explained that the distance between two adjacent correction wheels 10 on the same side is the same and they are symmetrically arranged on both sides of the conveying shaft 3, which can correct the woven bag evenly from both sides, further improving the correction effect.

[0034] like Figure 1 As shown, an anti-wrinkle mechanism is provided on the fixed frame 1, and the anti-wrinkle mechanism includes two fixed plates 11 fixed on the fixed frame 1, and two rollers 12 are rotatably connected between the two fixed plates 11. The two rollers 12 are connected by a long and wide conveyor belt 13. The outer walls of the rollers 12 and the conveying shaft 3 are both provided with spur gears 14, and the two spur gears 14 are meshed and connected. The outer walls of the two rollers 12 are both provided with conveying wheels that are compatible with the long and wide conveyor belt 13, and the outer walls of the rollers 12 and the conveying shaft 3 are both provided with pulleys that are compatible with the belt.

[0035] Further explanation is provided, two fixed plates 11, a roller 12 and a long and wide conveyor belt 13 are provided, and the roller 12 and the conveying shaft 3 are connected by a belt drive, so that when the woven bag is transmitted on the conveying sleeve 4, the long and wide conveyor belt 13 can rotate synchronously, which has a flattening effect on the woven bag, prevents the woven bag from wrinkles, and improves product quality.

[0036] The functional principle of this utility model can be explained through the following operation modes:

[0037] 1. Equipment Inspection and Preparation

[0038] Confirm that the position of the correction wheel 10 and the length and width conveyor belt 13 is correct, flush with the top of the conveying sleeve 4 and can function normally.

[0039] 2. Start the device

[0040] Turn on the power and start the motor 6. After the motor 6 starts, it drives the various conveying shafts 3 to rotate through the chain 5, ensuring that the conveying shafts 3 rotate synchronously, so that the woven bags can be smoothly transmitted on multiple conveying sleeves 4.

[0041] The transmission shaft 3 will drive the rotating shaft 8 to rotate through two staggered axis bevel gears 9, and the rotating shaft 8 will drive the multiple correction wheels 10 thereon to rotate. When the correction wheels 10 rotate, they can rub outward on the bottom of the woven bag so that the woven bag can be pulled by the rope, thereby allowing the correction wheels 10 to perform horizontal correction on the woven bag.

[0042] At the same time, the conveying shaft 3 drives the roller 12 to reverse through the engagement of two spur gears 14, which enables the long and wide conveyor belt 13 to flatten the woven bag and cooperate with multiple conveying sleeves 4 to prevent wrinkles on the surface of the woven bag.

[0043] 3. Place woven bags

[0044] Place the woven bag to be cut on the conveying sleeve 4, ensure that the position of the woven bag is centered and consistent with the conveying direction of the conveying shaft 3. During the conveying process of the woven bag, pay attention to whether it is correctly corrected by the correction wheel 10.

[0045] 4. Operation of lifting and cutting machine body 2

[0046] When the woven bag is transferred to the appropriate position, start the lifting cutting machine body 2 and adjust the cutting size and position as needed to ensure cutting accuracy. When the lifting cutting machine body 2 is cutting the woven bag, attention should be paid to safety to avoid hands or other parts of the body from touching the cutting part.

[0047] 5. Equipment Shutdown and Cleanup

[0048] After the cutting work is completed, first turn off the lifting cutting machine body 2, then turn off the motor 6, clean the woven bag residue and dust on the equipment, keep the equipment clean, regularly maintain and service the equipment, check the wear of each component, and replace damaged components in time to ensure the normal operation and service life of the equipment.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
