Abstract
Description
Technical Field
[0001] This application relates to the field of cardboard box processing equipment technology, and more specifically, to a corrugated cardboard box dryer. Background Technology
[0002] Corrugated cardboard boxes are three-dimensional packaging containers made from corrugated cardboard through processes such as die-cutting, creasing, stapling, or gluing. They consist of multiple layers, including a face paper, a core paper (corrugated paper), and a liner paper, providing excellent cushioning and compressive strength, effectively protecting goods from collisions and impacts during transportation.
[0003] In related technologies, corrugated cardboard boxes absorb a certain amount of moisture during the production process, especially in humid environments, where the moisture content of the corrugated cardboard increases. If not dried in time, this can easily lead to dimensional instability and poor bonding of the corrugated cardboard boxes.
[0004] Normally, workers place corrugated cardboard in a drying chamber and use hot air to adjust its moisture content, ensuring it reaches the ideal processing state. However, this process requires manual placement of the cardboard on the conveyor belt and manual removal of the dried cardboard.
[0005] Therefore, how to achieve automated drying is one of the urgent problems to be solved. Utility Model Content
[0006] In view of this, the present application provides a corrugated cardboard drying machine to solve the technical problem in the related art that requires manual drying of corrugated cardboard, resulting in low efficiency.
[0007] To achieve the above objectives, the embodiments of this application provide the following technical solutions:
[0008] A corrugated cardboard box dryer, comprising:
[0009] The drying chamber has a frame at the bottom and a fan drive device at the top. The inner top wall of the drying chamber is equipped with fan blades connected to the fan drive device. The drying chamber has an inlet and an outlet at both ends along its length.
[0010] A conveyor is provided inside the drying chamber and is used to transport objects from the inlet to the outlet.
[0011] The clamping guardrails are multiple in number and are fixedly connected to the conveyor chain of the conveyor, and the two are perpendicular to each other. The adjacent clamping guardrails are used to clamp the corrugated cardboard to be dried.
[0012] A placement workbench is provided on the side of the feeding end of the conveyor. A drive cylinder is provided on the placement workbench. The drive cylinder is used to push the corrugated cardboard toward the clamping guardrail, so that the corrugated cardboard moves laterally onto the clamping guardrail which is in a horizontal state.
[0013] In some possible implementations, the distance between the workbench and the conveyor is adapted to the width of the clamping guardrail.
[0014] In some possible implementations, both surfaces of the clamp guardrail are provided with polished surfaces.
[0015] In some possible implementations, a connecting rod is provided in the middle of the clamping guardrail, and multiple pulleys are rotatably provided in the middle of the connecting rod, the clamping guardrail being used to contact the corrugated cardboard through the pulleys.
[0016] In some possible implementations, the clamp guard is welded to the conveyor chain of the conveyor.
[0017] In some possible implementations, the conveyor chain is provided with a slot extending along its width, and the bottom end of the clamping guard is provided with a clamping plate, through which the clamping guard is inserted into the slot of the conveyor.
[0018] In some possible implementations, the bottom of the clamping guardrail is provided with a three-frame structure, and the plug-in plate is located at the bottom of the three-frame structure.
[0019] In some possible implementations, the conveyor chain of the conveyor is fixedly connected to the plug plate by hexagon socket bolts.
[0020] The corrugated cardboard box dryer provided in this application has at least the following beneficial effects:
[0021] In the corrugated cardboard box dryer provided in this application embodiment, the cardboard boxes to be dried are placed on the worktable, and then the stroke speed of the piston in the drive cylinder is adjusted to match the belt speed of the conveyor. Thus, when the conveyor's clamping guard rotates to a position parallel to the worktable, the drive cylinder pushes the corrugated cardboard onto the clamping guard. Subsequently, the clamping guard rotates with the conveyor, achieving automatic storage and drying functions. With this structural design, workers only need to place the corrugated cardboard on the worktable for automatic drying, significantly saving labor costs compared to traditional processes while also improving drying efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figures 1-5As shown in the illustration, the corrugated cardboard box dryer provided in this application includes a drying chamber 100, a conveyor 400, a clamping guardrail 500, and a worktable 600. The drying chamber 100 is used to dry the corrugated cardboard of the corrugated cardboard box. Due to the large size of the corrugated cardboard box, drying it presents many inconveniences and is prone to incomplete drying. In actual production, the corrugated cardboard is generally dried first, and its moisture content is controlled to a certain level before folding to obtain the dried corrugated cardboard box.
[0032] The bottom of the drying chamber 100 is mounted on the ground via a frame 200, and a fan drive device 300 is installed at the top of the drying chamber 100. A fan blade is fixedly connected to the drive end of the fan drive device 300, penetrating the top plate of the drying chamber 100 and located inside the chamber. The fan drive device 300 can drive the fan blade to rotate to achieve air blowing. Simultaneously, an electric heating wire is installed near the air outlet of the fan blade, which heats the air blown out by the fan blade, thereby achieving the function of hot air drying.
[0033] In this embodiment, the conveyor 400 is installed inside the drying chamber 100. The feed end of the conveyor 400 is located on the side of the feed inlet 110 of the drying chamber 100, and the discharge end of the conveyor 400 is located on the side of the discharge outlet 120 of the drying chamber 100. Therefore, the conveyor 400 can transport the corrugated cardboard to be dried from the feed inlet 110 to the discharge outlet 120 of the drying chamber 100, and subject it to hot air during the transport process to achieve drying.
[0034] Continue as Figure 1 and Figure 2 As shown, the conveyor 400 uses a conveyor chain as the transport medium. Clamping guardrails 500 are fixedly mounted on the conveyor chain of the conveyor 400, and the clamping guardrails 500 and the conveyor chain of the conveyor 400 are perpendicular to each other. Therefore, the clamping guardrails 500 can rotate cyclically along with the conveyor chain of the conveyor 400. Adjacent clamping guardrails 500 are used to clamp the corrugated cardboard to be dried, so that the corrugated cardboard can pass vertically through the drying chamber 100 and undergo hot air drying.
[0035] A workbench 600 is located beside the conveyor 400 in the drying chamber 100, specifically beside the discharge end of the conveyor 400. A drive cylinder 700 is mounted on the workbench 600, and corrugated cardboard to be dried is placed on its surface. In actual use, the operator can place the corrugated cardboard on the workbench 600 and use the drive cylinder 700 to push it laterally onto the clamping guardrail 500. Preferably, a push plate can also be provided on one side of the drive end of the drive cylinder 700, and the drive end of the drive cylinder 700 contacts the corrugated cardboard through the push plate.
[0036] In the corrugated cardboard box dryer provided in this embodiment, the cardboard boxes to be dried are placed on the worktable 600, and the stroke speed of the piston in the drive cylinder 700 is adjusted to match the belt speed of the conveyor 400. Thus, when the clamping guardrail 500 of the conveyor 400 rotates to a position parallel to the worktable, the drive cylinder 700 pushes the corrugated cardboard onto the clamping guardrail 500. Subsequently, the clamping guardrail 500 rotates with the conveyor 400, achieving automatic storage and drying. With this structural design, workers only need to place the corrugated cardboard on the worktable 600 to achieve automatic drying, significantly saving labor costs compared to traditional processes while also improving drying efficiency.
[0037] In some embodiments, the distance between the worktable 600 and the conveyor 400 is adapted to the width of the clamping guardrail 500. This prevents the clamping guardrail 500 from colliding with the worktable 600 as it rotates with the conveyor 400. Simultaneously, this minimizes the distance between the worktable 600 and the clamping guardrail 500, allowing corrugated cardboard to be smoothly pushed onto the clamping guardrail 500, preventing the cardboard from falling between the worktable 600 and the clamping guardrail 500.
[0038] In some embodiments, such as Figure 3 As shown, both surfaces of the clamping guardrail 500 are provided with polished surfaces 510. The smooth polished surfaces 510 allow corrugated cardboard to move more smoothly from the worktable 600 onto the clamping guardrail 500. Similarly, the corrugated cardboard can also fall quickly from the clamping guardrail 500 through the polished surfaces 510, thus facilitating its directional collection.
[0039] In some embodiments, a connecting rod 520 is provided in the middle of the clamping guardrail 500, and a plurality of pulleys 530 are provided in the middle of the connecting rod 520, such as... Figure 4As shown. The clamping guardrail 500 contacts the corrugated cardboard through a pulley 530. The pulley 530 can convert sliding friction into rolling friction, thereby reducing the wear and tear on the corrugated cardboard during movement.
[0040] In some embodiments, the clamping guardrail 500 can be welded to the conveyor chain of the conveyor 400. In other embodiments, such as Figure 5 As shown, the conveyor chain of the conveyor 400 has an insertion groove 410 at its end, which extends along the width direction of the conveyor chain. Correspondingly, the bottom of the clamping guardrail 500 has a three-frame structure 800, and the bottom of this three-frame structure 800 has an insertion plate 540. The clamping guardrail 500 can be inserted into the insertion groove 410 of the conveyor chain via the insertion plate 540, thus achieving a detachable connection.
[0041] Preferably, the conveyor chain of the conveyor 400 and the plug-in plate 540 can also be fixedly connected by hexagonal bolts 900. This method facilitates the disassembly and maintenance of the clamping guardrail 500 by staff, thereby ensuring the normal operation of the dryer.
