Description

Technical Field

[0001] The present invention relates to the field of carton processing, and particularly to a drying device for carton processing. Background Art

[0002] The cardboard used for corrugated cartons is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. In the process of corrugated paper processing, a drying device is required to dry the wet cardboard.

[0003] At present, there are still some deficiencies in the existing drying devices. During use, the cardboard is usually placed in a closed box, and hot air is used to dry the cardboard. However, when the drying is completed and the box needs to be opened to take out the cardboard, a large amount of heat energy in the box will be lost, and the box needs to be preheated again when drying the next batch of cardboard, which is very energy-consuming. Summary of the Invention

[0004] The purpose of the present invention is to provide a drying device for carton processing.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] A drying device for carton processing, including a box body. A hot air pipe connected to a hot air blower through a pipeline is laid on the bottom inside the box body. Air outlet holes are uniformly arranged on the side wall of the hot air pipe. A liquid driving mechanism is arranged at the middle of the bottom inside the box body. The liquid driving mechanism is connected to a support plate above it through a driving shaft. An insulating mechanism that can move up and down is arranged on the top wall inside the box body above the support plate. An inlet and outlet sealed by a cover plate is arranged on the top wall of the box body inside the opening of the insulating mechanism. A fixing mechanism is arranged on the support plate directly below the opening of the inlet and outlet.

[0007] The insulating mechanism includes a rectangular frame. The top end of the rectangular frame is connected to the top wall inside the box body through a canvas tube. A threaded hole screwed with a lead screw is also arranged on the side wall of the rectangular frame. The lead screw is driven by a motor.

[0008] Preferably, the fixing mechanism includes a bottom plate. Installation openings are arranged on the front and rear sides at both ends of the bottom plate. C-shaped rods with openings facing down are arranged on both sides of the top of the bottom plate. The two ends of the C-shaped rods pass through the corresponding installation openings. A rotating shaft embedded in the side wall of the installation opening is arranged on the rod body of the C-shaped rod. A spring connected to the corresponding side wall of the installation opening is arranged on the rod body of the C-shaped rod below the rotating shaft. A box body corresponding to the installation opening is arranged at the bottom of the support plate. A communication opening for the bottom end of the rod body of the C-shaped rod to pass through is arranged on the support plate inside the opening of the box body. A limiting block located at the bottom of the support plate is arranged on one side of the bottom end of the rod body of the C-shaped rod.

[0009] Preferably, limiting nets are arranged at the top edges of the support plates. The bottom plate is located between the four groups of limiting nets, and an arc-shaped guiding part is folded outward at the top end of the limiting net.

[0010] Preferably, the spring and the corresponding limiting block are arranged on the same side. The spring and the limiting block are arranged between the two C-shaped rods. The top ends of the C-shaped rods are connected to a hanging ring directly above the middle of the bottom plate through multiple cables.

[0011] Preferably, the liquid driving mechanism includes a housing located at the bottom inside the box. The housing is in a barrel-shaped structure arranged upside down. The driving shaft is located in the middle of the housing. Multiple pushing plates are radially arranged on the outer wall of the driving shaft inside the housing. A water inlet pipe I and a water outlet pipe I are tangentially arranged on the side wall of the housing. A water pump is arranged on the water inlet pipe I. A jacket is arranged outside the box. A heat preservation cavity is formed between the jacket and the side wall of the box. One end of the water inlet pipe I extends into the heat preservation cavity. The upper and lower ends of the side wall of the jacket are respectively provided with a water inlet pipe II and a water outlet pipe II communicating with the heat preservation cavity. A recovery pipe is also arranged outside the jacket. One end of the recovery pipe extends to the bottom inside the heat preservation cavity, and the other end of the recovery pipe is connected to an air collecting cover at the top inside the box. A suction fan is arranged on the recovery pipe.

[0012] Preferably, the box body is fixedly connected to the support plate. The top of the box body is open, and the inner diameter of the opening at the top of the box body is larger than that of the communication opening.

[0013] Preferably, a bearing for fixing the screw rod is arranged on the bottom wall inside the box. The screw rod is arranged inside the box outside the support plate. The edge of the support plate is located directly below the side wall of the rectangular frame.

[0014] The beneficial effects of the present invention are as follows: The present invention drives the support plate and the fixing mechanism to rotate through the liquid driving mechanism, so that the products on the fixing mechanism can fully contact the hot air flow inside the box, thereby improving the drying efficiency and effect. At the same time, the residual heat of the hot air flow inside the box can be recovered into the heat preservation cavity in the liquid driving mechanism to play a heat preservation role for the box, and the hot water heated by it can also be used for daily use. When taking out the products, by driving the canvas cylinder in the heat insulation mechanism to stretch, the support plate, the rectangular frame and the canvas cylinder can play a heat insulation role, so that when the import and export are opened to take out the products above the bottom plate, a large amount of hot air flow inside the box is prevented from flowing out through the opened import and export at this time, so as to reduce the heat loss inside the box.

[0027] The box body 96 is fixedly connected to the support plate 5. The top of the box body 96 is open. The inner diameter of the top opening of the box body 96 is larger than that of the communication opening 97;

[0028] The liquid driving mechanism 3 includes a housing 31 located at the inner bottom of the box body 1. The housing 31 has a barrel-like structure arranged in an inverted manner. The driving shaft 4 is located in the middle of the housing 31. A plurality of push plates 32 located inside the housing 31 are radially arranged on the outer wall of the driving shaft 4. A water inlet pipe I33 and a water outlet pipe I34 tangentially arranged with the side wall of the housing 31 are provided on the side wall of the housing 31. A water pump 35 is provided on the water inlet pipe I33. A jacket 36 is provided outside the box body 1. A heat preservation cavity 37 is formed between the jacket 36 and the side wall of the box body 1. One end of the water inlet pipe I33 extends into the heat preservation cavity 37. The upper and lower ends of the side wall of the jacket 31 are respectively provided with a water inlet pipe II38 and a water outlet pipe II39 communicating with the heat preservation cavity 37.

The other end of the recovery pipe 310 is connected to a wind collecting cover 311 at the inner top of the box body 1. An exhaust fan 312 is provided on the recovery pipe 310.

[0029] In this embodiment, a bearing for fixing the lead screw 63 is provided on the inner bottom wall of the box body 1. The lead screw 63 is arranged inside the box body 1 outside the support plate 5. The edge of the support plate 5 is located directly below the side wall of the rectangular frame 61.

[0030] Working principle of the present invention: The cardboard boxes are flattened and stacked on the bottom plate 91 and clamped by two sets of U-shaped rods 93. At this time, by means of the hoisting hook on the hanging ring 12, the bottom plate 91 and the products above it are lifted through the cable 11, the U-shaped rods 93 and the rotating shaft 94. At this time, the two sets of U-shaped rods 93 rotate in the installation opening 92 with the rotating shaft 94 as the center under the action of the upward pulling force, and at the same time stretch the spring 95, so that the two sets of U-shaped rods 93 are inclined to form an eight-shaped structure. Then, the bottom plate 91 is placed between the four sets of limit nets 10 in the box body 1 from the inlet and outlet 7. Since the four sets of limit nets 10 limit the horizontal displacement of the bottom plate 91, the bottom ends of the U-shaped rods 93 can quickly and smoothly pass through the corresponding communication openings 97 and slide into the box body 96. When the hoisting vehicle is separated from components such as the hanging ring 12, and the upward pulling force is lost, at this time, the spring 95 contracts and pulls the U-shaped rods 93 to rotate in the installation opening 92 with the rotating shaft 94 as the center, so that the U-shaped rods 93 drive the limit blocks 98 to buckle on the bottom of the support plate 5, so that the U-shaped rods 93 are in a vertical state. At this time, the support plate 5 abuts against the limit blocks 98 to prevent the U-shaped rods 93 from sliding out of the communication openings 97 on the support plate 5, thereby indirectly locking and fixing the bottom plate 91 on the support plate 5;

[0031] During use, hot air is sprayed through the hot air pipe 2 and the air outlet holes, so as to heat and dry the products above the bottom plate 91 in the box body 1. At this time, the gas after heating the products gathers at the top of the box body 1. Then, the exhaust fan 312 works to draw the airflow gathered at the top of the box body 1 into the liquid in the heat preservation cavity 37 through the recovery pipe 310 and the air collecting hood 311 for heating, so as to recycle the residual heat in the gas after heating the products. At this time, the liquid in the heat preservation cavity 37 can play a certain heat preservation role for the box body 1 after being heated, and at the same time, the heated liquid can be discharged through the water outlet pipe II 39 for daily use. In the above process, the liquid in the heat preservation cavity 37 can be pumped into the shell 31 through the water pump 35 and the water inlet pipe I 33 to push the push plate 32, so as to drive the drive shaft 4, the support plate 5, the bottom plate 91 and the products above it to rotate, so that the products in the rotation process can fully contact the hot air flowing in the box body 1, thereby improving its drying efficiency and effect. At this time, on the one hand, the limit net 10 can prevent the products on the bottom plate 91 from slipping, and on the other hand, it does not affect the flow of the air flow. At the same time, the liquid in the shell 31 finally flows back to the heat preservation cavity 37 through the water outlet pipe I 34 for recycling;

[0032] After drying is completed, the motor 64 drives the lead screw 63 to rotate in the threaded hole in the rectangular frame 61, thereby driving the rectangular frame 61 to move downward and abut against the top of the support plate 5. At this time, the rectangular frame 61 stretches the canvas tube 62, so that the bottom plate 91 and the product above it are located inside the opening of the canvas tube 62. At this time, the support plate 5, the rectangular frame 61 and the canvas tube 62 can play a heat insulation role, so that when the inlet and outlet 7 is opened to take out the product above the bottom plate 91, a large amount of hot air flow in the box body 1 is prevented from flowing out through the opened inlet and outlet 7 at this time, so as to reduce the loss of heat in the box body 1. At the same time, the hook of the traveling crane is connected to the hanging ring 12 and pulls the cable 11 upward. At this time, the cable 11 pulls the C-shaped rod 93 to rotate around the rotating shaft 94 in the installation opening 92 and stretch the spring 95. When the C-shaped rod 93 rotates, it will drive the limit block 98 to move out from the bottom of the support plate 5 and finally move to directly below the communication opening 97. Then, when the C-shaped rod 93 and the bottom plate 91 are lifted, the limit block 98 can be easily抽出 from the communication opening 97. When the bottom plate 91 is separated from the support plate 5, the above components can be smoothly lifted out from the inlet and outlet 7, so as to facilitate the removal of the product. Then, the product to be processed is placed on the support plate 5 through the fixing mechanism 9 and the inlet and outlet 7 is closed. At the same time, after the heat insulation mechanism 6 is reset, the next processing work can be carried out.

[0033] The present invention has been described in detail above, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
