Description

Technical Field

[0001] The invention relates to the field of packaging carton processing, and in particular to a drying device for packaging carton production. Background Art

[0002] Packaging cartons are utensils used to package various items. Packaging cartons are low-cost, easy to package, suitable for adding fillers and keeping clean, etc., which are suitable for product packaging before leaving the factory. Therefore, there is a high demand for packaging cartons. In the production of packaging cartons, the packaging cartons will be damp if they are stacked for a long time, so the packaging cartons need to be dried before use.

[0003] The current packaging carton drying device generally places the packaging carton to be dried on the top of the conveyor belt, and the conveyor belt conveys the packaging carton to be dried into the drying box. However, when the current packaging carton drying device is drying the packaging carton, since the packaging carton is placed on the conveyor belt, the bottom of the packaging carton is difficult to heat, and it is not convenient to fully dry both sides of the packaging carton, which leads to slow drying efficiency. In addition, the packaging carton is generally in a flat and unopened state during drying, which is not convenient for drying the inside of the packaging carton. Only the surface of the packaging carton is dried, which may also cause the packaging carton to deform, resulting in poor drying effect of the packaging carton. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned problem and provide a drying device for packaging carton production that can simultaneously dry both sides and the inside of a packaging carton, thereby drying the packaging carton more fully and comprehensively and flattening the dried packaging carton, thereby improving the drying effect and efficiency of the packaging carton.

The downward movement of one end of one of the transmission rods 88 will cause the other end of one of the transmission rods 88 to move upward. The upward movement of the other end of one of the transmission rods 88 will drive the next swing rod 87 to move upward and move in the direction away from the drying box 2. The upward movement of the next swing rod 87 and the movement in the direction away from the drying box 2 will drive the next slider 86 and the next transmission rod One end of 88 moves upward, and the upward movement of one end of the next transmission rod 88 will cause the other end of the next transmission rod 88 to move downward, and in this reciprocating manner, the swing rod 87 away from the rotating rod 82 reciprocates up and down and moves toward or away from the rotating rod 82, which will push the packaging carton to be dried at the bottom of the drying plate to move up and down and move toward the drying box 2, so that the packaging carton to be dried at the bottom of the drying box 2 will be moved into the drying box 2, and the hot air stirred by the guide plate 77 will dry the packaging carton more comprehensively and fully, thereby achieving a better drying effect for the packaging carton. After the drying is completed, the staff turns off the motor 75 and the hot air blower 72 and takes away the dried carton.

[0030] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, it also includes an unpacking component, which is used to squeeze the carton to be dried and arch it, and is arranged at the bottom of the base frame 1. The unpacking component includes a support block 91. The bottom of the base frame 1 is connected to two support blocks 91 by rivets. The two support blocks 91 are symmetrically arranged. The two support blocks 91 are slidably connected to a sliding frame 92. The two sliding frames 92 are composed of a bending rod and a fixed long rod fixedly connected to the bending rod. One of the transmission rods 88 is in contact with the two sliding frames 92. A push plate 93 is connected between the two sliding frames 92 by bolts, and a return spring 94 is connected between the support block 91 and the sliding frame 92 by a hook.

[0031] It also includes an anti-deformation component, which is used to flatten the dried carton. The anti-deformation component is arranged on the drying box 2, and the anti-deformation component is connected to the base frame 1. The anti-deformation component includes a paper pressing frame 101, and the paper pressing frame 101 is slidably connected to the drying box 2. The paper pressing frame 101 is slidably connected to the base frame 1, and the bottom of the paper pressing frame 101 is connected to the pressing plate 102 by bolts. Two return springs 103 are connected between the paper pressing frame 101 and the base frame 1 by hooks. The two return springs 103 are symmetrically arranged. The rotating rod 82 is connected to the pressing frame 104 by bolts. The pressing frame 104 consists of a rotating rod and an arc block fixedly connected to the rotating rod.

[0032] At first, one of the transmission rods 88 presses against the sliding frame 92, and the return spring 94 is stretched. One of the transmission rods 88 moves upward until it is out of contact with the sliding frame 92, and the return spring 94 will reset and drive the sliding frame 92 to move in the direction close to the swing rod 87. The movement of the sliding frame 92 in the direction close to the swing rod 87 will push one side of the carton to be dried, and the drying box 2 will press against the other side of the carton to be dried, so that the carton to be dried is arched, so that the inside of the carton to be dried can be dried, thereby improving the drying effect of the carton, and one of the transmission rods 88 moves downward to contact with the sliding frame 92 again, so that it can press the sliding frame 92 to move away from the swing rod 87 and reset, so that the sliding frame 92 is no longer in contact with the carton to be dried. When the carton moves to the bottom of the paper pressing frame 101, the rotation of the passive pulley 83 will drive the pressing frame 104 to rotate. During the rotation of the pressing frame 104, it will contact the pressing plate 102. When the pressing frame 104 rotates to contact with the pressing plate 102, the pressing frame 104 will press the pressing plate 102 to move downward. The downward movement of the pressing plate 102 will drive the paper pressing frame 101 to move downward, and the return spring 103 is compressed. The downward movement of the pressing frame 104 can flatten the deformed carton after drying, making the dried carton flatter. When the pressing frame 104 rotates to disengage from the pressing plate 102, the return spring 103 will reset and drive the paper pressing frame 101 to move upward and reset. The upward movement and reset of the paper pressing frame 101 will drive the pressing plate 102 to reset.

The bottom of the two-way air outlet pipe 111 is also fixedly connected to the air outlet box 2 113, and the two-way air outlet pipe 111 is communicated with the air outlet box 2 113.

[0034] A part of the hot air blown out by the dryer will be blown out through the two-way air outlet pipe 111, air outlet box 1 112 and air outlet box 2 113. When the inside of the carton to be dried is arched, the hot air blown out by air outlet box 112 and air outlet box 2 113 will concentrate on drying the bottom and the inside of the carton to be dried, so that the carton can be dried more comprehensively and fully, thereby improving the drying efficiency of the carton.

[0035] Embodiment 4: Based on the embodiment 3, Figure 1As shown, it also includes a guide plate 12. Two guide plates 12 are connected to the drying box 2 by rivets.

The guide plates 12 are respectively connected to the left limit plate 6 and the right limit plate 5 by bolts.

[0036] When the dried carton moves to the bottom of the guide plate 12, the dried carton will move along the curved surface of the guide plate 12, and the curved surface of the guide plate 12 will squeeze the dried carton, thereby facilitating the subsequent flattening of the dried carton.
