Description

Technical Field

[0001] This utility model relates to the field of moisture-proof PE ton bag processing technology, specifically a moisture-proof PE ton bag cutting machine. Background Technology

[0002] Moisture-proof PE ton bags are medium-sized bulk containers made primarily of polyethylene. They possess excellent chemical resistance, water resistance, abrasion resistance, tear resistance, and moisture resistance, and are widely used in logistics and packaging in industries such as chemical, building materials, food, and pharmaceutical.

[0003] During the processing of moisture-proof PE ton bags, the PE ton bag material is cut into specified rectangular sizes. Multiple rectangular ton bag pieces are then sewn together. During the cutting process, the PE ton bag material is conveyed by a conveyor device. During the cutting operation, the conveyor device intermittently stops conveying the PE ton bag material at the cutting position to control the stillness of the material at that position. The PE ton bag material to be cut will exceed the cutting device, thus cutting the stationary PE ton bag material. However, the material exceeding the cutting device... The moisture-proof PE ton bag material will be in a loose state. Therefore, when cutting the moisture-proof PE ton bag material with a cutting device, it will cause unevenness at the cut position, affecting the cutting quality. At the same time, when conveying the cut moisture-proof PE ton bag material, it is generally transported by a conveyor belt under the moisture-proof PE ton bag material. However, since the moisture-proof PE ton bag material and the conveyor belt are only transported by friction, relative sliding may occur between the conveyor belt and the moisture-proof PE ton bag material, affecting the stability of the conveying of the moisture-proof PE ton bag material.

[0004] The purpose of this invention is to provide a moisture-proof PE ton bag cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof PE ton bag cutting machine, comprising a conveyor frame, a cutting component installed at the top of one end of the conveyor frame, and a feeding component for conveying moisture-proof PE ton bags installed inside the top of the conveyor frame. The feeding component includes a conveyor belt, which is in contact with the moisture-proof PE ton bags. There are multiple conveyor belts. Fixed seats are symmetrically fixed on both sides of the end of the conveyor frame away from the cutting component by bolts. A drive shaft is rotatably mounted between two fixed seats by bearings. An mounting frame is rotatably mounted on the outer side of the drive shaft by bearings at equal intervals. An mounting shaft is rotatably mounted on the end of the mounting frame by bearings.

[0006] As a further preferred embodiment of this technical solution, the conveying rollers are positioned above the conveyor belt, and the number of conveying rollers corresponds to the number of conveyor belts.

[0007] As a further preferred embodiment of this technical solution, the feeding assembly further includes a transmission roller and a servo motor. Both ends of the conveyor frame are rotatably mounted with transmission rollers via bearings. The conveyor belt drive is installed between the two transmission rollers. One end of the conveyor frame is fixedly mounted with a servo motor via bolts. The output shaft of the servo motor is fixedly connected to one end of the transmission roller via a shaft connector.

[0008] As a further preferred embodiment of this technical solution, the end of the transmission roller is connected to the transmission shaft.

[0012] This utility model provides a moisture-proof PE ton bag cutting machine, which has the following beneficial effects:

[0013] (1) This utility model uses a feeding assembly to transport moisture-proof PE ton bag material to the top of the conveyor belt of the conveyor frame, and the conveyor belt continuously transports the moisture-proof PE ton bag material. The gravity between the mounting frame and the conveyor roller will drive the conveyor roller to always be in contact with the upper surface of the conveyor belt. As the moisture-proof PE ton bag material is transported, the moisture-proof PE ton bag material will pass through the area between the lower part of the conveyor roller and the upper surface of the conveyor belt. At the same time, by controlling the rotation of the conveyor roller, the moisture-proof PE ton bag material between the conveyor roller and the conveyor belt can be continuously transported and tightened, thereby improving the flatness of the cutting assembly on the moisture-proof PE ton bag material and improving the cutting quality.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a moisture-proof PE ton bag cutting machine includes a conveyor frame 1. A cutting component 2 is installed on the top of one end of the conveyor frame 1. A feeding component for conveying moisture-proof PE ton bags is installed inside the top of the conveyor frame 1. The feeding component includes a conveyor belt 31, which is in contact with the moisture-proof PE ton bag. There are multiple conveyor belts 31. Fixed seats 4 are symmetrically fixed on both sides of the end of the conveyor frame 1 away from the cutting component 2 by bolts. A drive shaft 5 is rotatably installed between two fixed seats 4 by bearings. An mounting frame 6 is rotatably installed on the outer side of the drive shaft 5 by bearings at equal intervals. An mounting shaft 7 is rotatably installed on the end of the mounting frame 6 by bearings. A conveying roller 8 is fixedly installed on one end of the mounting shaft 7. The conveying roller 8 rotates in the opposite direction to the conveyor belt 31. The conveying roller 8 is positioned above the conveyor belt 31, and the number of conveying rollers 8 corresponds to the number of conveyor belts 31. The moisture-proof PE ton bag material is conveyed to the top of the conveyor frame 1 by the feeding component. Above the conveyor belt 31 at the end, the moisture-proof PE ton bag material is continuously conveyed by the conveyor belt 31. The gravity between the mounting frame 6 and the conveyor roller 8 ensures that the conveyor roller 8 remains in contact with the upper surface of the conveyor belt 31. As the moisture-proof PE ton bag material is conveyed, it passes through the area between the lower part of the conveyor roller 8 and the upper surface of the conveyor belt 31. Simultaneously, by controlling the rotation of the conveyor roller 8, the moisture-proof PE ton bag material between the conveyor roller 8 and the conveyor belt 31 is continuously conveyed. The ton bag material is continuously conveyed and tightened, thereby improving the flatness of the cutting component 2 in cutting the moisture-proof PE ton bag material and improving the cutting quality. Since the conveyor roller 8 and the conveyor belt 31 rotate synchronously in opposite directions, and the moisture-proof PE ton bag material can be controlled between the conveyor roller 8 and the conveyor belt 31 under the pressure of the gravity of the conveyor roller 8, the synchronous conveying of the moisture-proof PE ton bag material by the conveyor roller 8 and the conveyor belt 31 can be realized after the moisture-proof PE ton bag material is cut, ensuring the stability of the conveying of the cut moisture-proof PE ton bag material.

[0022] like Figures 1 to 4 As shown, the feeding assembly also includes a transmission roller 32 and a servo motor 33. Both ends of the conveyor frame 1 are rotatably mounted with transmission rollers 32 via bearings. The conveyor belt 31 is driven and installed between the two transmission rollers 32. One end of the conveyor frame 1 is fixedly mounted with a servo motor 33 by bolts. The output shaft of the servo motor 33 is fixedly connected to one end of the transmission roller 32 via a shaft connector.

[0023] The operation of the servo motor 33 drives the transmission roller 32 to rotate. The transmission between the conveyor belt 31 and the two transmission rollers 32 can control the continuous conveying of the conveyor belt 31, so as to lay the moisture-proof PE ton bag material above the conveyor belt 31 on the upper surface of the conveyor frame 1.

[0024] like Figures 1 to 4As shown, the end of the transmission roller 32 is connected to the transmission shaft 5. A first pulley 9 is fixedly installed at one end of the transmission roller 32, which is connected to the output shaft of the servo motor 33. A rotating shaft 10 is rotatably installed on one side of the conveyor frame 1 at a position below the end of the transmission shaft 5 via a bearing. A second pulley 11 is fixedly installed at the end of the rotating shaft 10. A first transmission belt 12 is installed between the second pulley 11 and the first pulley 9. A driven gear 13 is fixedly installed at the end of the transmission shaft 5. A driving gear 14 is fixedly installed on the outer side of the rotating shaft 10 at a position below the driven gear 13. The driving gear 14 is meshed with the driven gear 13.

[0025] When the servo motor 33 drives the conveyor belt 31 to transport the moisture-proof PE ton bag material above the conveyor belt 31, the operation of the servo motor 33 will synchronously drive the first pulley 9 to rotate. The transmission between the second pulley 11 and the first pulley 9 through the first transmission belt 12 will drive the rotating shaft 10 to rotate, which will in turn drive the drive gear 14 to rotate. The meshing of the drive gear 14 and the driven gear 13 will drive the transmission shaft 5 to rotate.

[0026] like Figures 1 to 4 As shown, a third pulley 15 is fixedly installed at equal intervals on the outer side of the drive shaft 5, and a fourth pulley 16 is fixedly installed on the end of the mounting shaft 7 away from the conveying roller 8. A second drive belt 17 is connected between the fourth pulley 16 and the third pulley 15.

[0027] When the drive shaft 5 rotates, the transmission between the fourth pulley 16 and the third pulley 15 via the second drive belt 17 will drive the mounting shaft 7 to rotate, which is used to control the synchronous rotation of the conveyor roller 8.

[0028] like Figures 1 to 4 As shown, counterweight columns 18 are fixedly installed between several of the mounting brackets 6.

[0029] The counterweight column 18 can increase the gravity of the conveyor roller 8, increase the force of the conveyor roller 8 pressing down on the moisture-proof PE ton bag material, and increase the frictional contact force between the moisture-proof PE ton bag material and the conveyor belt 31.

[0030] This utility model provides a moisture-proof PE ton bag cutting machine, the specific working principle of which is as follows:

[0031] In operation, the device conveys the moisture-proof PE ton bag material to the conveyor belt 31 at the top of the conveyor frame 1 via the feeding assembly. Simultaneously, the servo motor 33 controls the rotation of the transmission rollers 32. The transmission between the conveyor belt 31 and the two transmission rollers 32 controls the continuous conveying of the conveyor belt 31, ensuring the moisture-proof PE ton bag material is laid flat on the upper surface of the conveyor frame 1. Gravity between the mounting frame 6 and the conveyor rollers 8 keeps the conveyor rollers 8 in constant contact with the upper surface of the conveyor belt 31. As the moisture-proof PE ton bag material is conveyed, it passes through the area between the conveyor rollers 8 and the upper surface of the conveyor belt 31. Simultaneously, the servo motor 33 drives the first pulley 9 to rotate. The transmission between the first transmission belt 12 and the second pulley 11 and the first pulley 9 drives the rotating shaft 10 to rotate, which in turn drives the drive gear 14 to rotate. The meshing of the driven gear 13 with the drive shaft 4 will drive the drive shaft 5 to rotate. At the same time, the transmission between the fourth pulley 16 and the third pulley 15 through the second drive belt 17 will drive the mounting shaft 7 to rotate, which is used to control the rotation of the conveyor roller 8. At this time, the rotation of the conveyor roller 8 and the conveyor belt 31 is opposite, and the conveyor belt 31 moves away from the end of the cutting assembly 2. Therefore, the moisture-proof PE ton bag material between the conveyor roller 8 and the conveyor belt 31 can be continuously conveyed and tightened, thereby improving the flatness of the cutting of the moisture-proof PE ton bag material by the cutting assembly 2 and improving the cutting quality. Since the conveyor roller 8 and the conveyor belt 31 rotate synchronously in opposite directions, and the moisture-proof PE ton bag material can be controlled between the conveyor roller 8 and the conveyor belt 31 under the pressure of the gravity of the conveyor roller 8, the moisture-proof PE ton bag material can be cut. After the moisture-proof PE ton bag material is cut, the synchronous conveying of the moisture-proof PE ton bag material by the conveyor roller 8 and the conveyor belt 31 can be realized, ensuring the stability of the conveying of the cut moisture-proof PE ton bag material.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
