Description

Technical Field

[0001] The utility model relates to the technical field of woven bag hot cutting, in particular to a hot cutting device for woven bag processing. Background Art

[0002] Woven bags are a common packaging material. During the processing of woven bags, they need to be cut by a hot cutting machine to achieve the purpose of cutting and separating the entire woven bag. Some woven bags are processed with a hot cutting device. Through bearings and movable rods, the two pressure wheels will slide in opposite directions to straighten the material, so that the material can be pressed and straightened during cutting to prevent wrinkles in the material. Subsequently, the hydraulic rod is used to drive the hot cutter to move vertically downward through the control element, and the high temperature generated by the hot cutter itself is used to hot cut the woven bag. However, the hot cutter will melt the cutting edge of the woven bag and stick to both sides of the hot cutter during cutting, and the woven bags on both sides will be moved upward by the blade when the hot cutter is reset. There are safety hazards in removing the woven bag by hand close to the high-temperature blade. At the same time, due to the hot-melt cutting of the woven bag by the hot cutter, the solidified residue after the hot cutting of the woven bag will adhere to the surface of the blade, which requires regular cleaning by the staff, increasing the workload of the staff.

[0022] Hot cutting table 1: a hot cutting frame 4 is provided in the middle of the upper side thereof, an electric push rod 5 is provided on the upper side of the hot cutting frame 4, a lifting seat 6 is provided at the telescopic end of the electric push rod 5, a hot cutting knife 7 is installed on the lower side of the lifting seat 6, a ceramic heating strip 8 is provided inside the hot cutting knife 7, a conveyor 3 is provided between the front and rear walls of the hot cutting table 1, the input end of the conveyor 3 is electrically connected to the output end of the single chip computer 2, a hot cutting knife seat 10 is provided in the middle of the upper side of the hot cutting table 1, the hot cutting knife seat 10 is respectively installed with the hot cutting knife 7 and the conveyor 3, and the upper left and right edges of the hot cutting knife seat 10 are arc When the device is used to perform hot cutting on the woven bag, first, the single chip computer 2 starts the conveyor 3, and the belt on the conveyor 3 uses contact friction to perform hot cutting and conveying on the woven bag. When the woven bag moves to the hot cutting knife seat 10, the woven bag slides toward the upper side along the arc chamfer of the hot cutting knife seat 10 to avoid the edge angle of the hot cutting knife seat 10 interfering with the movement of the woven bag. The hot cutting knife seat 10 prevents the hot cutting knife 7 from contacting with the belt on the conveyor 3 when hot cutting the woven bag, thereby protecting the conveyor 3 from hot cutting.

[0023] Anti-adhesion mechanism 9: It is arranged on the left and right sides of the lifting seat 6. The anti-adhesion mechanism 9 includes a connecting seat 91, a telescopic column 92, a spring 93 and a lower pressure seat 94. The connecting seat 91 is respectively arranged on the left and right sides of the lifting seat 6. The lower side of the connecting seat 91 is provided with a lower pressure seat 94 through evenly distributed telescopic columns 92 and springs 93. The springs 93 are movably connected to the outer ends of the adjacent telescopic columns 92. The lower side of the lower pressure seat 94 is provided with evenly distributed semicircular grooves. The anti-adhesion mechanism 9 also includes a telescopic column 95, a spring 96 and an arc-shaped scraper seat 97. The telescopic column 95 is evenly arranged on one side of the lower pressure seat 94 close to the center of the hot cutting table 1. The longitudinally adjacent telescopic columns 92 are arranged on the lower side of the lower pressure seat 94. 5, there is an arc-shaped scraper seat 97 between the telescopic ends, and there is a uniformly distributed spring 2 96 between the lower pressure seat 94 and the adjacent arc-shaped scraper seat 97. The spring 2 96 is movably sleeved with the outer end of the adjacent telescopic column 2 95. The anti-adhesion mechanism 9 also includes a rotating ball 98, and the rotating ball 98 is rotatably connected in the semicircular groove. When the woven bag is hot-cut, the single-chip microcomputer 2 starts the ceramic heating plate 8 to heat the blade of the hot cutting knife 7, and then the single-chip microcomputer 2 starts the electric push rod 5 to make its telescopic end drive the lifting seat 6 to move vertically downward. During the downward movement of the lifting seat 6, the lower pressure seat 94 first contacts the edge of the hot cutting part of the woven bag. As the hot cutting knife 7 continues to move downward, the telescopic end of the telescopic column 1 92 and the spring 96 are in contact with each other. Spring 1 93 contracts, and when the hot cutting knife 7 moves down to contact with the arc scraper seat 97, the contact pressure causes the telescopic end of telescopic column 2 95 and spring 2 96 to contract, and the distance between the two arc scraper seats 97 increases. Then the hot cutting knife 7 cooperates with the hot cutting knife seat 10 to perform hot cutting on the woven bag. Then the single chip computer 2 controls the electric push rod 5 to contract and reset its telescopic end. In this process, the compression elastic force of spring 1 93 causes the lower pressing seat 94 to squeeze the woven bag, thereby preventing the woven bag from moving upward with the hot cutting knife 7 due to the hot melting phenomenon during the hot cutting process when the hot cutting knife 7 moves up and resets. As the hot cutting knife 7 moves up and resets, the compression elastic force of spring 2 96 causes the arc scraper to The material seat 97 performs a scraping treatment on the blade surface of the hot cutting knife 7 to prevent the hot-cutting melted residue of the woven bag from remaining on the hot cutting knife 7, which is convenient to use. The lower pressing seat 94 applies pressure to the hot-cutting part of the woven bag by rotating the ball 98 to reduce the contact pressure surface, so as to prevent the hot-cutting part of the woven bag from moving up due to the squeezing adhesion force when the lower pressing seat 94 moves up and resets later. The hot-cutting device for woven bag processing can automatically squeeze the hot-cutting part of the woven bag through the elastic element to prevent it from moving as the hot-cutting knife 7 moves up and resets, which is safe to use. At the same time, the device can automatically clean the hot-cutting residue of the woven bag on the blade surface of the hot cutting knife 7 through the elastic element, without the need for manual cleaning later, and is convenient to use.

[0024] Among them: it also includes a single-chip microcomputer 2, which is arranged on the front side of the hot cutting table 1. The input end of the single-chip microcomputer 2 is electrically connected to the external power supply, and the output end of the single-chip microcomputer 2 is electrically connected to the input ends of the electric push rod 5 and the ceramic heating strip 8 respectively, so that the control of electrical components is convenient.

[0025] The working principle of a hot cutting device for woven bag processing provided by the utility model is as follows: when the device is used to perform hot cutting processing on the woven bag, first the single chip microcomputer 2 starts the conveyor 3, and the belt operation on the conveyor 3 utilizes the contact friction force to perform hot cutting processing and conveying on the woven bag. When the woven bag moves to the hot cutting knife seat 10, the woven bag slides toward its upper side along the arc chamfer of the hot cutting knife seat 10 to prevent the edge angle of the hot cutting knife seat 10 from interfering with the movement of the woven bag. The hot cutting knife seat 10 prevents the hot cutting knife 7 from contacting with the belt on the conveyor 3 when hot cutting the woven bag, thereby protecting the conveyor 3 from hot cutting. When hot cutting the woven bag, the single chip microcomputer 2 starts the ceramic heating plate 8 to heat the blade of the hot cutting knife 7. Subsequently, the single chip microcomputer 2 starts the electric push rod 5 so that its telescopic end drives the lifting seat 6 to move vertically downward. During the downward movement of the lifting seat 6, the lower pressing seat 94 first contacts the edge of the hot cutting part of the woven bag. As the hot cutting knife 7 continues to move downward, the telescopic end of the telescopic column 92 and the spring 93 contract. When the hot cutting knife 7 When it moves down to contact with the arc scraper seat 97, the contact pressure causes the telescopic end of the telescopic column 2 95 and the spring 2 96 to contract, and the distance between the two arc scraper seats 97 increases. Then the hot cutter 7 cooperates with the hot cutter seat 10 to perform hot cutting on the woven bag. Then the single chip computer 2 controls the electric push rod 5 to contract and reset its telescopic end. In this process, the compression elastic force of the spring 1 93 causes the lower pressing seat 94 to squeeze the woven bag, thereby preventing the woven bag from being squeezed due to hot cutting when the hot cutter 7 moves up and resets. The hot melting phenomenon in the process moves upward with the hot cutter 7. As the hot cutter 7 moves up and resets, the arc-shaped scraper seat 97 scrapes the blade surface of the hot cutter 7 through the compression elastic force of the spring 2 96 to avoid the hot-cut melted residue of the woven bag remaining on the solidified hot cutter 7. It is easy to use. The lower pressure seat 94 applies pressure to the hot-cut part of the woven bag through the rotating ball 98 to reduce the contact pressure surface, so as to avoid the hot-cut part of the woven bag moving up due to the extrusion adhesion force when the lower pressure seat 94 moves up and resets in the later stage.

[0026] It is worth noting that the single chip microcomputer 2 disclosed in the above embodiment can adopt MSP430, the conveyor 3 can adopt QL-020 belt conveyor, the electric push rod 5 can adopt DTZ630, and the ceramic heating strip 8 can adopt MCH ceramic heating sheet. The single chip microcomputer 2 controls the conveyor 3, the electric push rod 5 and the ceramic heating strip 8 to work using methods commonly used in the prior art.
