Description

Technical Field

[0001] This utility model relates to the field of plastic packaging bag production technology, and in particular to a cutting device for producing plastic packaging bags. Background Technology

[0002] Plastic packaging bags are packaging bags made from plastic raw materials. They are lightweight, waterproof, and corrosion-resistant, making them an important tool in modern logistics and commodity circulation. Plastic packaging bags have a wide range of applications, including food, daily necessities, chemical products, and express delivery packaging. To improve the sealing, durability, and safety of the packaging, the production process of plastic packaging bags requires an edge trimming step, which necessitates the use of edge trimming devices for plastic packaging bag production. A search revealed that Chinese Patent CN221953993U discloses a cutting device for biodegradable plastic packaging bags, belonging to the technical field of biodegradable plastic packaging bag production equipment. The device includes a portal frame, with a first pneumatic rod and a second pneumatic rod fixedly connected to the upper part of the portal frame. A cutter is fixedly connected to the lower end of the first pneumatic rod, and a guide post is fixedly connected to the lower end of the second pneumatic rod. A spring frame is slidably mounted on the outside of the guide post, and a tension spring is movably sleeved on the lower part of the guide post. The guide post drives the tension spring to move downwards, causing the tension spring to drive the spring frame and move the pressure block downwards. When the pressure block presses onto the target biodegradable plastic packaging bag, the elastic force of the tension spring acts on the spring frame, creating an outward unfolding force at the lower part of the spring frame. When the biodegradable plastic packaging bag wrinkles, the pressure block flattens the bag, improving the flatness of the biodegradable plastic packaging bag before cutting and ensuring cutting stability.

[0003] The above technical solution can only flatten a single plastic bag before replacing it with the next plastic bag that needs to be trimmed. It cannot continuously transport and trim multiple plastic bags. In mass production, this can easily lead to low efficiency and is not well-suited for assembly line production. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0018] In order to solve the problems existing in the background art, this application proposes the following technical solution: a cutting device for producing plastic packaging bags.

[0019] The specific technical solution includes a side plate 1 and a continuous feeding assembly 2; like Figure 1-4As shown, the continuous feeding assembly 2 is used to convey and trim plastic packaging bags. The continuous feeding assembly 2 is mounted on the side plate 1 and includes a servo motor 201, a roller 202, a servo motor 203, a drive shaft 204, and a driven shaft 205. The servo motor 201 drives the roller 202 to rotate, the servo motor 203 drives the drive shaft 204 to rotate, the drive shaft 204 drives the conveyor belt 206 to rotate, and the driven shaft 205 supports the conveyor belt 206 simultaneously with the drive shaft 204. The servo motor 201 is fixedly mounted on the outside of the side plate 1. Roller 202 is fixedly connected to the output shaft of servo motor 201. Roller 202 is rotatably mounted on side plate 1. Servo motor 203 is fixedly mounted on the outside of side plate 1. Drive shaft 204 is fixedly connected to the output shaft of servo motor 203. Drive shaft 204 and driven shaft 205 are rotatably mounted on side plate 1. Conveyor belt 206 is sleeved on the outside of drive shaft 204 and driven shaft 205. The side wall of conveyor belt 206 and the side wall of roller 202 are pressed against each other. Conveyor belt 206 can synchronously drive the plastic packaging bag to move with roller 202. Conveyor belt 206 is sleeved on the outside of one side of roller 202.

[0020] according to Figure 2 As shown, the plastic packaging bag is placed between roller 202 and conveyor belt 206 from the upper left, with the edge of the plastic packaging bag to be cut aligned with the blade of cutting disc 303. Simultaneously, servo motors 1 (201) and 2 (203) are activated. Servo motor 1 (201) drives roller 202 to rotate clockwise, and servo motor 2 (203) drives drive shaft 204 to rotate counterclockwise. Drive shaft 204 drives conveyor belt 206 to rotate counterclockwise, and conveyor belt 206 drives driven shaft 205 to rotate counterclockwise. The plastic packaging bag is thus clamped between roller 202 and conveyor belt 206, and roller 202 and conveyor belt 206 can pull the plastic packaging bag into roller 202. Between the roller 202 and the conveyor belt 206, after the first plastic bag enters between the roller 202 and the conveyor belt 206, the second plastic bag is immediately placed in, and so on, multiple plastic bags can be placed in. The plastic bags rotate clockwise around the outer wall of the roller 202 between the roller 202 and the conveyor belt 206. The plastic is squeezed onto the side wall of the roller 202 by the conveyor belt 206. After the plastic bag contacts the cutting disc 303, due to the driving of the roller 202 and the conveyor belt 206 and the rotation of the cutting disc 303, the cutting disc 303 can cut the edges of the plastic bag. The roller 202 and the conveyor belt 206 can convey the plastic bag while the cutting disc 303 cuts the edges.

[0021] like Figure 1 and Figure 3-4As shown, a cutting assembly 3 is installed on one side of the roller 202 and the conveyor belt 206. The cutting assembly 3 is used to cut the edges of the plastic packaging bags conveyed by the continuous feeding assembly 2. The cutting assembly 3 includes a bracket 301, a servo motor 302, and a cutting disc 303. The bracket 301 can fix the servo motor 302. The servo motor 302 can drive the cutting disc 303 to rotate. The cutting disc 303 can cut the edges of the plastic packaging bags. The servo motor 302 is fixedly installed on the bracket 301. The cutting disc 303 is fixedly connected to the output shaft of the servo motor 302. The cutting disc 303 is located on one side of the roller 202 and the conveyor belt 206.

[0022] The cutting edge of the cutting disc 303 is pressed against the side wall of the roller 202, and the cutting disc 303 and the roller 202 rotate in opposite directions. Figure 3 As shown, when the roller 202 rotates clockwise, the bracket 301 fixes the servo motor 302. When the servo motor 302 starts, it can drive the cutting disc 303 to rotate counterclockwise. The cutting line of the plastic packaging bag that needs to be cut is between the conveyor belt 206, the roller 202 and the cutting disc 303. The cutting disc 303 can cut the plastic packaging bag. The cut plastic packaging bag falls into the feed port 6 and can be collected. The waste generated by cutting can enter between the limit plate 4 and the cutting disc 303 and fall into the feed port 6 to prevent the waste from accumulating on the processing table 5.

[0023] like Figure 1 and Figure 3-4 As shown, the side wall of the roller 202 is equipped with a limiting plate 4, which can limit the trajectory of the waste material generated by the cutting edge, and prevent the waste material from accumulating on the processing table 5. The cutting disc 303 is located between the conveyor belt 206 and the limiting plate 4.

[0024] like Figure 1 and Figure 3-4 As shown, a processing table 5 is fixedly installed below the side plate 1. The processing table 5 can fix the side plate 1 and the bracket 301. The continuous feeding component 2 and the cutting component 3 are located above the processing table 5. The bracket 301 and the limiting plate 4 are fixedly connected to the processing table 5. The processing table 5 has a discharge port 6, which facilitates the falling of plastic packaging bags and waste materials and prevents the plastic packaging bags and waste materials from accumulating on the processing table 5. The limiting plate 4 is located above the discharge port 6.

[0025] like Figure 1 As shown, an arc-shaped plate 7 is inserted inside the conveyor belt 206. The arc-shaped plate 7 can support the inner side wall of the conveyor belt 206 away from the roller 202, preventing the inner sides of the conveyor belt 206 from squeezing and rubbing against each other. The arc-shaped plate 7 is fixedly connected to the side plate 1.

[0026] like Figure 3As shown, a servo motor 48 is fixedly installed below the processing table 5. The servo motor 48 can drive the scroll 9 to rotate. The scroll 9 is rotatably installed below the processing table 5. The scroll 9 can wind up plastic packaging bags that have not been cut into individual pieces. The scroll 9 is fixedly connected to the output shaft of the servo motor 48 and is located below the feed port 6.

[0027] When trimming the edges of plastic bags that have not been cut into individual pieces, the plastic bags are connected to each other. After the plastic bags are trimmed between the roller 202 and the cutting disc 303, they leak out from below between the roller 202 and the conveyor belt 206, and are wound onto the reel 9. When the roller 202 and the conveyor belt 206 are conveying the plastic bags, the servo motor 8 is started to drive the reel 9 to rotate. The reel 9 can rewind the trimmed plastic bags that have not been cut into individual pieces.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
