Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a preheating roller for corrugated board production. Referring to fig. 1, a preheating roller for corrugated cardboard production includes a base frame 1, the base frame 1 is rotatably connected with a preheating roller 11, the preheating roller 11 is hollow, and the preheating roller 11 is arranged along the length direction of the base frame 1. One end of the base frame 1 is fixedly connected with a servo motor 12 corresponding to the position of the preheating roller 11, an output shaft of the servo motor 12 is arranged along the length direction of the base frame 1, and an output shaft of the servo motor 12 penetrates through one end of the base frame 1 and is fixedly connected with the preheating roller 11. An oil inlet pipe 13 is fixedly connected to one end, far away from the servo motor 12, of the preheating roller 11, the oil inlet pipe 13 is communicated with the preheating roller 11, and the oil inlet pipe 13 penetrates through the base frame 1. When the paper preheating device is used, hot oil is conveyed into the preheating roller 11 through the oil inlet pipe 13, then the servo motor 12 is started, the servo motor 12 drives the preheating roller 11 to rotate, the hot oil transfers heat to the preheating roller 11, and the preheating roller 11 can preheat paper materials while conveying the paper materials.

Referring to fig. 1 and 2, a plurality of first scrapers 2 are fixedly connected in the preheating roller 11, the first scrapers 2 are arranged along the length direction of the preheating roller 11, the first scrapers 2 are arranged along the circumferential array of the inner wall of the preheating roller 11, and two ends of the first scrapers 2 are respectively abutted against two ends of the inner wall of the preheating roller 11. Every first scraper blade 2 is kept away from the equal fixedly connected with second scraper blade 21 of preheating roller 11 one end, and second scraper blade 21 sets up along the length direction of first scraper blade 2, and second scraper blade 21 sets up to keeping away from the slope of first scraper blade 2 one end by being close to first scraper blade 2 one end, and second scraper blade 21 both ends butt respectively in the both ends of preheating roller 11 inner wall. When the paper preheating device is used by a user, the first scraper 2 and the second scraper 21 hold hot oil, the hot oil gradually rises along with the rotation of the preheating roller 11 and falls down when being positioned at the top of the preheating roller 11, so that all parts of the outer surface of the preheating roller 11 are uniformly heated, and the efficiency and the effect of preheating paper are ensured.

Referring to fig. 1 and 2, each of the second scrapers 21 is provided with a plurality of oil outlet holes 211, and the oil outlet holes 211 are arranged in an array along the length direction of the second scrapers 21. When the preheating roller is used by a user, hot oil in the first scraper 2 and the second scraper 21 flows out through the oil outlet 211 along with the rotation process of the preheating roller 11, and the hot oil flows through the inner walls of the first scraper 2 and the preheating roller 11, so that the inner wall and the outer wall of the preheating roller 11 are heated more uniformly. Every second scraper blade 21 keeps away from the equal fixedly connected with third scraper blade 22 of first scraper blade 2 one end, and third scraper blade 22 sets up to keeping away from second scraper blade 21 one end slope by being close to second scraper blade 21 one end, and third scraper blade 22 both ends butt respectively in the both ends of preheating roller 11 inner wall. When the user uses the oil preheating device, the third scraper 22 slows down the speed of hot oil flowing down from the first scraper 2 and the second scraper 21, so that the hot oil stays on the first scraper 2 and the second scraper 21 for a longer time, and the preheating effect is improved.

Referring to fig. 1 and 2, a plurality of oil-lubricant ring grooves 111 are formed in the inner wall of the preheating roller 11, and the oil-lubricant ring grooves 111 are arranged in an array along the longitudinal direction of the preheating roller 11. When the user uses the oil scraper, the hot oil on the first scraper 2 and the second scraper 21 flows into the oil scraper ring groove 111, and the hot oil flows in the oil scraper ring groove 111 and flows to the bottom of the preheating roller 11 under the action of gravity, so that the speed of heat transmission of the hot oil to the preheating roller 11 is increased.

Referring to fig. 1 and 3, an oil drain hole 112 is formed at a position of the preheating roller 11 near the edge, and a sealing cover 113 having elasticity is engaged in the preheating roller 11 corresponding to the oil drain hole 112. When the user uses the oil-discharging preheating device, the user pulls down the sealing cover 113, rotates the preheating roller 11, and discharges hot oil when the oil-discharging hole 112 is at a lower position, so that the user can conveniently replace the hot oil in the preheating roller 11.

Referring to fig. 1 and 4, the base frame 1 is fixedly connected with support plates 3 at positions close to both ends, and the support plates 3 are fixedly connected at positions close to the bottom of the base frame 1. Logical groove 31 has all been seted up to every backup pad 3, and every backup pad 3 corresponds equal sliding connection in leading to groove 31 and has a connection roller 4, connects roller 4 and all increases gradually by the radius at center to both ends along its axial. The two connecting rollers 4 are connected to a tension roller 41 so as to be rotated together on the side close to each other. When a user uses the paper, the paper passes through the lower part of the tension roller 41, and the connecting roller 4 and the tension roller 41 apply downward tension to the paper due to gravity factors, so that the paper is kept in a tight state, and the paper is prevented from being wrinkled. Meanwhile, the radius of the center of the connecting roller 4 is small, and the radius of the two ends of the connecting roller is large, so that the connecting roller 4 is prevented from sliding out of the through groove 31, and the normal movement of the connecting roller 4 is guaranteed.

The implementation principle of the preheating roller for corrugated board production is as follows: when the paper preheating device is used by a user, hot oil is conveyed into the preheating roller 11 through the oil inlet pipe 13, then the servo motor 12 is started, the servo motor 12 drives the preheating roller 11 to rotate, the heat of the hot oil is transferred to the preheating roller 11, paper materials pass through the upper portion of the preheating roller 11, the paper materials pass through the lower portion of the tensioning roller 41 after passing through the preheating roller 11, and the preheating roller 11 also conducts preheating treatment on the paper materials when transmitting the paper materials, so that the quality of the paper materials is guaranteed. The paper is in a tight state under the action of gravity of the tension roller 41, and the paper is prevented from wrinkling in the conveying process. In the rotation process of the preheating roller 11, hot oil flows into the first scraper 2, the second scraper 21 and the third scraper 22 and moves along with the rotation process of the preheating roller 11, meanwhile, part of the hot oil flows out through the oil outlet 211 and the oil scraper groove 111, and the rest of the hot oil flows down when reaching the top of the preheating roller 11, so that the heating degree of each part of the outer surface of the preheating roller 11 is more uniform, the preheating effect of the preheating roller 11 on paper is improved, and the quality of the paper is ensured.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
