Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, in particular to a woven bag packaging machine with a compression function. Background Art

[0002] Woven bags are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. With the continuous development of industry and agriculture, and the continuous growth of the logistics and transportation industry, the demand for woven bags is also increasing year by year. In particular, the transportation of grain products such as rice basically involves the demand for woven bags. Therefore, a large number of woven bags need to be packaged. When traditional packaging machines are used, the woven bags become fluffy after filling and take up a lot of space for transportation and storage. The efficiency of using manual assisted compression is low.

[0003] Publication No. CN109160012A discloses a woven bag sealing device with a compression function. Through a compression mechanism, the contents inside the woven bag can be compressed. Compared with existing compression mechanisms, this compression mechanism can fix the woven bag through a fixing component, preventing the woven bag from tilting and the contents from falling out, thereby improving the stability of the sealing device. Through the sealing mechanism, sealing at different heights can be performed to meet actual needs. Compared with existing sealing mechanisms, this sealing mechanism can retract the sealing machine into the lifting block for protection, reducing the probability of damage to the sealing machine. However, this patent still has the following problems during actual use: Although the woven bag sealing device with a compression function can compress the contents of the woven bag by setting a compression mechanism, it is not convenient to control the compressed shape of the woven bag during compression.

At the same time, the lifting threaded sleeve 227 drives the mounting bracket 101 to move up and down, thereby realizing the lifting and moving of the woven bag. The conveying roller 208 is used to realize the tilting of the woven bag, which is convenient for beating the woven bag and making the woven bag shrink evenly. The volume of the woven bag after shrinkage is neat, which is convenient for uniform stacking of the woven bag.

[0023] Working principle: Before using this woven bag packing machine with compression function, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 11 As shown, first, the multi-stage telescopic cylinder 104 is used to move telescopically, and under the action of the first rotating support 103, the second rotating support 105 and the connecting hinge 107, the rotation of the flapping bracket 106 is realized, and the flapping motor 110 is started to drive the first sprocket transmission assembly 111 and the flapping moving threaded rod 112 to rotate, so that the moving threaded sleeve 113 drives the rotating connecting shaft 114, the rotating gear 115 and the flapping rotating roller 116 to move along the direction of the flapping moving threaded rod 112, and at the same time, the meshing connection between the rotating gear 115 and the meshing rack 118 is used. The characteristics of the slapping roller 116 are used to realize the rotation of the rotating connecting shaft 114 and the slapping rotating roller 116, and the slapping protrusion 117 on the outside of the slapping rotating roller 116 is used to slap the woven bag, which can not only slap the breathable woven bag to evenly distribute the material inside the woven bag, but also when the sealed woven bag is vacuumed, the material inside the woven bag is evenly distributed by slapping. During vacuuming, it can ensure that the woven bag is evenly vacuumed, and there will be no uneven shrinkage of the woven bag, which will affect the shape of the woven bag after vacuuming and the stacking and storage of the woven bag.

[0024] Secondly, by starting the clamping motor 120 to drive the clamping bidirectional threaded rod 121 to rotate, the two clamping threaded sleeves 122 drive the limiting clamping plate 123 to move relative to each other, and the anti-slip groove 124 is used to stably clamp the woven bag. Since the limiting clamping plate 123 is limited and slidably connected to the clamping bracket 119, the rotation of the clamping bidirectional threaded rod 121 will not cause the limiting clamping plate 123 to rotate together. When the woven bag needs to be vacuumed, the vacuum nozzle 126 is inserted into the top of the woven bag and the vacuum fan 129 is started for vacuuming. The bag opening of the woven bag can be manually pressed to improve the vacuuming efficiency. The dustproof net 127 can prevent the goods from entering the vacuum box 125, thereby affecting the vacuuming of the woven bag. The compression cylinder 131 drives the compression plate 132 to rotate, which can compress the breathable woven bag and seal the woven bag in cooperation with the sealing equipment. The sealing equipment is a prior art and is not the main technical point of this case. Therefore, the sealing equipment is not described in detail.

[0025] Finally, the controller 202 is used to control the conveying motor 206 to drive the second sprocket transmission assembly 204 to rotate. Under the limiting action of the sprocket limiting groove 203 and the limiting bar 205, the rotation of the conveying driven sprocket 207 can be realized, avoiding the phenomenon of the conveying driven sprocket 207 being de-toothed. The second sprocket transmission assembly 204 and the conveying driven sprocket 207 drive the conveying roller 208 to rotate, which not only realizes the conveying of the woven bag, but also when the woven bag is vacuumed, the conveying motor 206 is started in the reverse direction to make the conveying roller 208 rotate in the opposite direction.
