Description

Technical Field

[0001] This utility model relates to the field of drying racks, and in particular to a drying rack for a drying machine used in the production of honeycomb cardboard. Background Technology

[0002] Honeycomb paperboard is made based on the principle of honeycomb structure in nature. It is a new type of environmentally friendly and energy-saving sandwich structure material made by bonding corrugated base paper into countless hollow three-dimensional regular hexagons to form a whole load-bearing component, namely the paper core, and then bonding face paper to both sides. After the paper core and face paper are bonded, they need to be sent to a drying machine to dry and cure. In the drying machine, a drying rack is used to support and place the paperboard.

[0003] While existing drying racks offer good load-bearing capacity and can separate cardboard sections through grooves to improve the drying effect of honeycomb cardboard, they also have other problems during use. For example, they lack adjustable spacing, the two baffles are fixed in assembly during installation, and can only limit the movement of a single specification of honeycomb cardboard. If the cardboard is too short, its ends cannot be inserted into the grooves, resulting in poor flexibility. Furthermore, they lack a drop cushioning function, and during the vertical drop of the honeycomb cardboard, the surface grip is too weak, making it easy for personnel to slip and cause the cardboard to fall too quickly or too heavily. Rigid impacts between the honeycomb cardboard and the base plate can easily cause damage and excessive wear. To solve the above problems, we propose a drying rack for a drying machine used in the production of honeycomb cardboard. Utility Model Content

[0004] The purpose of this invention is to provide a drying rack for a drying machine used in the production of honeycomb paperboard, which solves the problems that existing drying racks do not have adjustable spacing and do not have a drop buffer function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a drying rack for a drying machine used in the production of honeycomb paperboard, comprising a fixed frame, two base plates bolted inside the fixed frame, a limiting plate placed on the top of the base plates, threaded rods symmetrically welded on the front and back of the limiting plates, sliding grooves provided on the front and back of the fixed frame, the other end of the threaded rods extending to the outside of the sliding grooves and threadedly connected to a fixing nut, grooves provided on opposite sides of the two limiting plates, a buffer plate provided inside the grooves, a buffer spring bolted between the bottom of the buffer plate and the grooves by a spring fixing piece, and a rubber pad bolted to the top of the buffer plate.

[0006] The above technical solution has an adjustable spacing function, which is suitable for placing and limiting various sizes of cardboard. It is simple and convenient to operate, which improves the flexibility of the device. At the same time, it has a drop buffer function, which can reduce the force of the cardboard falling too fast, improve the protection effect and safety of the cardboard, and has high practicality.

[0007] The present invention is further configured such that: a spring washer is slidably sleeved on the surface of the threaded rod, and the spring washer is located between the fixing bracket and the fixing nut.

[0008] By adopting the above technical solution and setting the spring washer, the fixing effect of the fixing nut after tightening can be improved, and it can play a role in preventing loosening.

[0009] The present invention is further configured such that: a caster wheel is installed at the bottom of the base plate, and a brake pad is installed on the surface of the caster wheel.

[0010] By adopting the above technical solution, the use of casters and brake pads makes it easy for personnel to pull the fixing frame out and push it in from inside the drying machine.

[0011] The present invention is further configured such that a damper is installed between the bottom of the buffer plate and the groove.

[0012] By adopting the above technical solution, the damper can be used to suppress the bounce of the buffer spring and consume the kinetic energy stored in the buffer spring, thereby reducing the resonance amplitude and improving stability.

[0013] The present invention is further configured such that both the threaded rod and the fixing nut are made of stainless steel.

[0014] Using the above technical solution, the threaded rod and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The present invention is further configured such that the buffer spring is made of carbon spring steel.

[0016] Using the above technical solution, the buffer spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model involves first pulling the fixing frame out of the drying machine, calculating the length of the honeycomb cardboard after the fixing frame is pulled out, and then grasping the limiting plate by hand and moving it inward. When the limiting plate moves inward, it will drive the threaded rod and the fixing nut to move together. When the limiting plate moves inward to a suitable distance, the fixing nut can be tightened with a tool. It has the function of adjustable spacing, is suitable for putting in and limiting cardboard of various specifications, is simple and convenient to operate, and improves the flexibility of the device.

[0019] 2. This utility model lifts the honeycomb cardboard to a position above the limiting plate, then vertically lowers the cardboard. During the lowering process, both sides of the cardboard must be positioned within the grooves of the limiting plate. If the cardboard is lowered too quickly and contacts the rubber pad, it will cause the buffer plate to move downwards. As the buffer plate moves downwards, it will compress the buffer spring and damper. When the buffer spring and damper contract, they absorb and offset the impact force, thus providing a drop buffer function. This reduces the force of the cardboard falling too quickly, improving the protection and safety of the cardboard and making it highly practical. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] refer to Figure 1 , Figure 2 and Figure 3 A drying rack for a drying machine used in the production of honeycomb cardboard includes a fixed frame 1. Two base plates 2 are bolted inside the fixed frame 1. A limiting plate 3 is placed on the top of the base plates 2. Threaded rods 4 are symmetrically welded to the front and back of the limiting plate 3. Sliding grooves 5 are provided on both the front and back of the fixed frame 1. The other end of the threaded rod 4 extends to the outside of the sliding groove 5 and is threadedly connected to a fixing nut 6. The device is operated by first pulling the fixed frame 1 out of the drying machine, calculating the length of the honeycomb cardboard, and then grasping the limiting plate 3 and moving it inwards. As the limiting plate 3 moves inwards, it drives the threaded rods 4 and the fixing nut 6 to move together. Once the limiting plate 3 has moved to the appropriate distance, the fixing nut 6 is tightened with a tool. This device features adjustable spacing, is suitable for placing and limiting various specifications of cardboard, is simple and convenient to operate, and improves the flexibility of the device.

[0027] refer to Figure 2A spring washer 11 is slidably fitted onto the surface of the threaded rod 4. The spring washer 11 is located between the fixing bracket 1 and the fixing nut 6. By setting the spring washer 11, the fixing effect of the fixing nut 6 after tightening can be improved, and it plays a role in preventing loosening.

[0028] refer to Figure 1 The bottom of the base plate 2 is equipped with casters 12, and brake pads are installed on the surface of the casters 12. The casters 12 and brake pads make it easy for personnel to pull the fixing frame 1 out and push it in from the inside of the drying machine.

[0029] refer to Figure 1 and Figure 2 Both the threaded rod 4 and the fixing nut 6 are made of stainless steel, and have the characteristics of high strength, low density and excellent corrosion resistance.

[0030] Brief description of the usage process: First, pull the fixing frame 1 out of the drying machine. After pulling the fixing frame 1 out, calculate the length of the honeycomb paperboard. Then, grasp the limiting plate 3 by hand and move it inward. When the limiting plate 3 moves inward, it will drive the threaded rod 4 and the fixing nut 6 to move together. When the limiting plate 3 moves inward to a suitable distance, tighten the fixing nut 6 with a tool.

[0031] Example 2:

[0032] refer to Figure 1 , Figure 2 and Figure 3 A drying rack for a drying machine used in the production of honeycomb paperboard has grooves 7 on opposite sides of two limiting plates 3. A buffer plate 8 is installed inside the groove 7. A buffer spring 9 is bolted between the bottom of the buffer plate 8 and the groove 7 via a spring fixing piece. A rubber pad 10 is bolted to the top of the buffer plate 8. The honeycomb paperboard is raised above the top of the limiting plates 3, and then vertically lowered. When the paperboard is lowered, both sides must be placed in the grooves 7 within the limiting plates 3. If the paperboard is lowered too quickly and comes into contact with the rubber pad 10, it will cause the buffer plate 8 to move downwards. As the buffer plate 8 moves downwards, it will compress the buffer spring 9 and the damper 13. When the buffer spring 9 and the damper 13 contract, they absorb and offset the impact force, thus providing a drop buffer function. This reduces the force of the paperboard falling too quickly, improving the protection and safety of the paperboard and making it highly practical.

[0033] refer to Figure 3 A damper 13 is installed between the bottom of the buffer plate 8 and the groove 7. The damper 13 can suppress the jumping of the buffer spring 9 and consume the kinetic energy stored in the buffer spring 9, thereby reducing the resonance amplitude and improving stability.

[0034] refer to Figure 3The buffer spring 9 is made of carbon spring steel and has excellent mechanical properties, good spring damping performance, low temperature resistance and corrosion resistance.

[0035] Brief description of the usage process: The honeycomb cardboard is raised to a height above the limit plate 3, and then the cardboard is placed vertically downwards. When the cardboard is lowered, both sides should be placed in the grooves 7 inside the limit plate 3. If the cardboard is lowered too quickly and comes into contact with the rubber pad 10, it will cause the buffer plate 8 to move downwards. When the buffer plate 8 moves downwards, it will press the buffer spring 9 and the damper 13. When the buffer spring 9 and the damper 13 contract, they will absorb and offset the impact force.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
