Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard production, and more specifically, to a corrugating mechanism for corrugated cartons. Background Technique

[0002] , Corrugated cartons are made of corrugated cardboard. Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper sandwich (commonly known as "pit paper", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of cardboard (also known as "liner board", "box board paper"). It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself. In corrugated cardboard production, mainly local method straw pulp and waste paper are beaten into pulp to make a raw cardboard similar to yellow cardboard, then mechanically processed into a corrugated shape, and then glued to the box board paper with adhesives such as sodium silicate on its surface, and finally dried and formed.

[0003] Currently, in the drying and forming of corrugated cardboard, the corrugated cardboard is mainly placed on a conveyor, and then hot air is blown onto the top of the corrugated cardboard to promote the drying and forming of the corrugated cardboard. Corrugated cardboard is divided into single-layer and multi-layer. When the existing corrugating mechanism of corrugated cartons dries multi-layer corrugated cardboard, when blowing hot air from the top, the top corrugated cardboard contacts the hot air earlier, while the bottom corrugated cardboard contacts the hot air later. Therefore, when the top corrugated cardboard is dried and shaped, the bottom corrugated cardboard is still in a wet state, which easily causes the top corrugated cardboard to crush the bottom corrugated cardboard, thus affecting the quality of the corrugated cardboard. In view of this, we propose a corrugating mechanism for corrugated cartons. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a corrugating mechanism for corrugated cartons to solve the technical problem that when the existing corrugating mechanism of corrugated cartons blows hot air from the top to dry multi-layer corrugated cardboard, it is easy to cause the collapse of the corrugated cardboard at the bottom.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A corrugating mechanism for corrugated cartons, including an equipment frame, a conveyor is arranged on the equipment frame, and a drying mechanism is covered on the conveying surface of the conveyor;

[0006] The drying mechanism includes a U-shaped support plate and a hot air blower. The two ends of the bottom of the U-shaped support plate are fixedly connected to the two sides of the top of the equipment frame. A number of blowing nozzles are evenly arranged through the two sides of the U-shaped support plate at equal intervals. The hot air blower is fixedly installed at the bottom of the equipment frame by screws. The output end of the hot air blower is communicated with the input ends of a number of the blowing nozzles through a hose, and the output ends of a number of the blowing nozzles all point to the conveying surface of the conveyor.

[0007] Preferably, mounting grooves penetrating through both sides of the U-shaped support plate are formed on both sides of the U-shaped support plate, and the output end of the blowing nozzle penetrates through the mounting groove and extends into the U-shaped support plate.

[0008] Preferably, sliding rails are provided on the inner walls of the top and bottom of the mounting groove along the U-shaped support plate. Sliders are provided at the positions of the top and bottom of the blowing nozzle relative to the sliding rails. The surface of the sliding rail is slidably connected to the inner wall of the slider, and a reciprocating component is provided on the top of the U-shaped support plate.

[0009] Preferably, the reciprocating component includes a motor and a long shaft. The motor is fixedly installed on the top surface of the U-shaped support plate by screws. The middle of the long shaft is rotationally connected to the top surface of the U-shaped support plate through a mounting bearing. The output end of the motor is transmitted to the middle of the long shaft through a bevel gear set. Both ends of the long shaft extend to both sides of the U-shaped support plate and are fixedly connected with discs. One side of the opposite side of the two discs is rotationally connected with a connecting rod through a rotating shaft. One end of the connecting rod is rotationally connected with a gear through a short shaft. A rack A is engaged at the top of the gear. One side of the rack A is fixedly connected to the top of the U-shaped support plate through a mounting plate. A rack B is engaged at the bottom of the gear. The bottom of the rack B is fixedly connected with a connecting plate. The bottom of the connecting plate is fixedly connected with a plurality of blowing nozzle mounting sections through screws.

[0010] Preferably, the output end of the blowing nozzle is flat.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The drying mechanism designed by the present utility model abandons the method of drying corrugated paperboard by blowing air from the top in the prior art. The hot air blower forms hot air and is conveyed by a hose to the blowing nozzles on both sides of the U-shaped support plate and blown out. By adopting the side-blowing drying method, the hot air can be blown into the corrugated paperboard from the corrugated gaps of the corrugated paperboard, thereby drying and shaping multiple layers of corrugated paperboard, and effectively preventing the phenomenon of collapse of the corrugated paperboard at the bottom layer.

[0013] 2. The present utility model also designs a reciprocating mechanism. The motor drives the long shaft to rotate through a bevel gear set. The long shaft drives the discs at both ends to rotate. The discs drive the connecting rod to perform eccentric motion through the rotating shaft. Since one side of the rack A is fixedly connected to the top of the U-shaped support plate through a mounting plate, the connecting rod drives the rack B to perform reciprocating movement through the gear. The rack B drives a plurality of blowing nozzles on both sides of the U-shaped support plate to perform reciprocating movement in the mounting groove through the slider and the sliding rail through the connecting plate, making the corrugated paperboard heat more evenly and improving the speed of drying and forming of the corrugated paperboard.

The output end of the hot air blower 302 is communicated with the input ends of a number of air blowing nozzles 303 through a hose. The output ends of a number of air blowing nozzles 303 all point to the conveying surface of the conveyor 2. By driving the hot air blower 302 through an external control mechanism, the hot air blower 302 forms hot air and transports it to the air blowing nozzles 303 on both sides of the U-shaped support plate 301 through the hose and blows out. By adopting the side-blow drying method, the hot air can be blown into the corrugated cardboard through the corrugation gaps of the corrugated cardboard, thereby accelerating the drying and shaping of the multi-layer corrugated cardboard.

[0021] Furthermore, as Figures 1 to 3As shown, mounting grooves 3011 penetrating both sides of the U-shaped support plate 301 are provided on both sides of the U-shaped support plate 301, the output end of the blowing nozzle 303 is penetrated through the mounting groove 3011 and extends to the inside of the U-shaped support plate 301, and slide rails 3012 are provided along the top and bottom inner walls of the mounting groove 3011 of the U-shaped support plate 301, and sliders 3031 are provided at the top and bottom of the blowing nozzle 303 relative to the slide rails 3012, and the surface of the slide rails 3012 is slidably connected to the inner wall of the slider 3031, and a reciprocating component 304 is provided on the top of the U-shaped support plate 301, and the reciprocating component 304 is used to drive a plurality of blowing nozzles 303 on both sides of the U-shaped support plate 301 to reciprocate in the mounting groove 3011 through the sliders 3031 and the slide rails 3012, so that the corrugated cardboard is heated more evenly.

[0022] In further, Figure 3 As shown, the reciprocating assembly 304 includes a motor 3041 and a long shaft 3042. The motor 3041 is fixedly installed on the top surface of the U-shaped support plate 301 by screws. The middle part of the long shaft 3042 is rotatably connected to the top surface of the U-shaped support plate 301 through a mounting bearing. The output end of the motor 3041 is transmitted to the middle part of the long shaft 3042 through a bevel gear set.
