Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard printing and drying equipment, and relates to an environmentally friendly cardboard printing and drying device for cartons. Background Technology

[0002] Carton printing is a process that creates patterns, text, and logos on the surface of cartons to enhance product brand recognition.

[0003] When printing patterns, text, and logos on cardboard boxes, existing equipment uses natural air drying, which makes the printed graphics and logos on the top surface easily damaged during the stacking process after the cardboard is conveyed by the cardboard conveyor, affecting the printing effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an environmentally friendly cardboard printing and drying device for cardboard boxes, which can quickly dry the printed cardboard graphics and text, and avoid damage to the graphics and text during the stacking of cardboard.

[0005] To solve the technical problem to be addressed by this utility model, the technical solution adopted by this utility model is as follows: an environmentally friendly cardboard printing and drying device for cardboard boxes, comprising a support frame and an exhaust fan. Two supports are arranged at intervals along the conveying direction of the cardboard conveyor belt. The supports are U-shaped with support legs at both ends, and the support legs are fixedly connected to the frame of the cardboard conveyor belt. The housing of the exhaust fan is fixedly connected to the top of the two supports. Two exhaust fans are provided and arranged at intervals along the length of the supports. The exhaust side of the exhaust fan faces the top conveyor section of the conveyor belt of the cardboard conveyor belt.

[0006] Furthermore, the bottom of the casing of the two exhaust fans is provided with a flange around the perimeter. The flange is fixedly connected to two inlay grooves on the support plate and is fixed with fastener one. The middle of the inlay groove is a ventilation hole, the diameter of which is the same as the inner diameter of the cylindrical casing of the exhaust fan. The support plate is provided with two guide grooves at the bottom of both ends facing the two brackets. The two guide grooves are inserted into the horizontal section of the bracket and fixed with fastener two.

[0007] Furthermore, the height of the bracket facing the feed side of the cardboard conveyor belt is higher than that of the other bracket on the discharge side.

[0008] Furthermore, the upper and lower ends of the support legs on the same side of the two aforementioned brackets are connected by crossbars, and the support legs are provided with multiple evenly spaced through holes along their length. The support legs are fixed to the frame by bolts through the through holes.

[0009] The beneficial effects of this utility model are as follows: Compared with the prior art, the effects of this utility model are as follows: 1) The present invention uses two exhaust fans installed above the cardboard conveyor belt to blow and dry the printed cardboard graphics and markings, which can greatly improve the drying efficiency and effectively prevent the cardboard from being damaged during stacking. 2) The use of a support plate with an embedded groove for mounting two exhaust fans enables quick installation and positioning of the exhaust fans, improving installation efficiency. The guide groove allows for quick positioning of the support plate onto the bracket, and also facilitates positioning of the bracket along its length. This allows for quick adjustment and positioning when drying a batch of cardboard at different conveying positions. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of an environmentally friendly cardboard printing and drying device for cardboard boxes. Figure 2 This is a side view of an environmentally friendly cardboard printing and drying device for cardboard boxes. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] Example 1: Refer to Figure 1-2 As shown, an environmentally friendly cardboard printing and drying device for cartons includes a support frame 1 and an exhaust fan 2. Two supports 1 are arranged at intervals along the conveying direction of a cardboard conveyor belt 3. The cardboard conveyor belt 3 uses multiple narrow belts arranged at intervals, with gaps between the belts to facilitate the fall of waste strips after printing and cutting. The support frame 1 is U-shaped, with support legs 101 at both ends, which are fixedly connected to the frame 301 of the cardboard conveyor belt 3. The housing 201 of the exhaust fan 2 is fixedly connected to the top of the two supports 1. Two exhaust fans 2 are arranged at intervals along the length of the support frame 1. The exhaust side of the exhaust fan 2 faces the top conveyor section of the conveyor belt 302 of the cardboard conveyor belt 3. The conveyor belt 302 of the cardboard conveyor belt 3 conveys cardboard 5. The two exhaust fans installed above the cardboard conveyor belt dry the printed graphics and markings on the cardboard, greatly improving drying efficiency and effectively preventing damage to the graphics and markings during cardboard stacking.

[0013] To facilitate the installation of two exhaust fans 2, a flange 202 is provided around the bottom of the casing of the two exhaust fans 2. The flange 202 is fixedly connected to two inlay grooves 401 on the support plate 4 using fastener one, which is a screw. The bottom of the support plate 4 facing the two brackets 2 has two guide grooves 402. The two guide grooves 402 are inserted into the horizontal section 102 of the bracket 1 and fixed with fastener two, which is a set screw. The set screw is spirally connected from the side of the guide groove and abuts against the bracket. The support plate 4 with inlay grooves is used to install two exhaust fans 2, which can realize the quick installation and positioning of the exhaust fans 2 and improve the installation efficiency. The guide grooves can quickly position the support plate onto the bracket and facilitate the positioning of the bracket in the length direction. When drying a batch of cardboard at different conveying positions, the positioning can be quickly adjusted. The middle of the inlay groove 401 is a ventilation hole 403, and the diameter of the ventilation hole 403 is the same as the inner diameter of the cylindrical casing of the exhaust fan 2.

[0014] To improve the drying effect, the support 1 on the feeding side of the cardboard conveyor belt 3 is higher than the other support 1 on the discharging side. This structure enables the exhaust fan to blow air towards the feeding side, and the airflow is introduced onto the belt on the feeding side, thereby achieving better drying on the feeding side.

[0015] To achieve synchronous lifting and adjustment, the upper and lower ends of the support legs 101 on the same side of the two brackets 1 are connected by crossbars 103. The support legs 101 have multiple evenly spaced through holes 104 along their length. The support legs 101 are fixed to the frame 301 by bolts through the through holes 104. The use of multiple evenly spaced through holes allows the bracket to be installed at different heights. After adjustment, bolts are used to fix the bracket by passing through the corresponding through holes and the mounting holes on the frame of the cardboard conveyor. The adjustment is convenient and quick. The crossbar connection allows for synchronous lifting and adjustment, making the adjustment faster and the installation more convenient. The crossbars that are fixedly connected at the upper and lower ends improve the stability of the entire exhaust fan support frame.

[0016] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
