Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, specifically to a cost-saving double-sided machine for corrugated cardboard box production. Background Technology

[0002] Corrugated boxes are a widely used packaging material made of corrugated cardboard. The structural design of corrugated boxes gives them good cushioning performance and strength, which can protect the contents from damage during transportation and storage. Currently, the corrugated cardboard used in the production of corrugated boxes needs to be bonded together with the single-sided cardboard and the face paper using a double-sided machine.

[0003] A search revealed a corrugated cardboard double-facer with publication number CN216001644U. This machine allows for adjustment of the position between two adjusting plates. The combined use of these two plates helps to straighten the corrugated cardboard, preventing it from becoming skewed and improving the processing yield. Furthermore, the machine utilizes an exhaust duct, a suction fan, a return air duct, a heat pipe, and a nozzle to quickly dissipate heat from the laminated corrugated cardboard, facilitating the forming of the laminated corrugated cardboard.

[0004] However, due to the relatively fixed exhaust range of the heat pipe in the above technical solution, when the distance between the two adjusting plates becomes smaller, some of the gas inside the heat pipe is easily sprayed onto the non-corrugated cardboard area, resulting in wasted airflow.

[0005] Based on this, we propose a cost-saving double-sided machine for corrugated cardboard box production. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a cost-saving double-sided machine for corrugated cardboard box production, which solves the technical problem in the prior art where the exhaust range of the heat pipe is relatively fixed, and when the distance between the two adjusting plates becomes smaller, some of the gas in the heat pipe is easily sprayed into the non-corrugated cardboard area, resulting in wasted airflow.

[0007] According to one aspect, at least one embodiment of the present invention provides an economical double-sided machine for corrugated cardboard box production, comprising a heat-laminating box and a cooling box, wherein the cooling box is fixedly connected to one end of the heat-laminating box, and further comprising:

[0008] An adjusting cylinder is fixedly connected to the top of the heat-laminating box at the end away from the cooling box. An assembly frame is fixedly connected to the output end of the adjusting cylinder. A limit component is provided at the bottom of the assembly frame. The limit component is used to restrict the path of the corrugated cardboard into the heat-laminating box. A preheating component is provided on one side of the assembly frame.

[0009] An external exhaust fan is fixedly connected to the top of the heat-bonding box near the cooling box. An external exhaust pipe is fixedly connected to the input end of the external exhaust fan, and the bottom end of the external exhaust pipe extends into the interior of the heat-bonding box. An air supply pipe is fixedly connected to the output end of the external exhaust fan. The air supply pipe is used to preheat the corrugated cardboard in conjunction with the preheating assembly.

[0010] For example, in at least one embodiment of this utility model, a cost-saving double-facer for corrugated cardboard box production includes a limiting component comprising:

[0011] Two push rods are slidably connected to both ends of the assembly frame. A limit plate is fixedly connected to the end of the push rod located inside the assembly frame, and a push frame is fixedly connected to the end of the push rod located outside the assembly frame. A push plate is rotatably connected to the top of the push frame.

[0012] A transmission seat is fixedly connected to the top of the assembly frame. Both ends of the transmission seat are rotatably connected to a transmission shaft. An eccentric plate and a linkage spur gear are fixedly connected to the outer side of the transmission shaft. The two linkage spur gears are meshed together. The ends of the two push plates away from the push frame are rotatably connected to the ends of the two eccentric plates respectively.

[0013] A drive motor is fixedly connected to one side of the drive base, and the output end of the drive motor is fixedly connected to one of the drive shafts.

[0014] For example, in at least one embodiment of this utility model, a cost-saving double-facer for corrugated cardboard box production includes a preheating component comprising:

[0015] Two extension seats are fixedly connected to both ends of the assembly frame, and a diversion pipe is fixedly connected between the two extension seats. Multiple outlet pipes are fixedly connected to the bottom end of the diversion pipe.

[0016] Two flow control rods are slidably connected to both ends of the flow divider tube, and the end of the flow control rod near the pusher is fixedly connected to the pusher tube. A flow control plate is fixedly connected to the end of the flow control rod inside the flow divider tube.

[0017] The transmission pipe is fixedly connected to the middle of the top of the split pipe, and the end of the transmission pipe away from the split pipe is also connected to the gas supply pipe.

[0018] For example, in at least one embodiment of this utility model, a double-sided machine for producing economical corrugated boxes is provided, which further includes: a stabilizing rod fixedly connected to the inner side of the assembly frame, a stabilizing hole opened at the top of the limiting plate, and the stabilizing hole and the stabilizing rod are in clearance fit.

[0019] For example, in at least one embodiment of this utility model, a double-sided machine for producing economical corrugated boxes is provided, which further includes: an assembly rod fixedly connected to the top of the pusher frame and one end of the eccentric plate, and the two ends of the pusher plate are respectively rotatably connected to the two assembly rods.

[0020] For example, in at least one embodiment of this utility model, a double-sided machine for producing economical corrugated boxes is provided, which further includes: a protective shell is fixedly connected to the side of the transmission base near the linkage spur gear, and the linkage spur gear is located inside the protective shell.

[0021] For example, in at least one embodiment of this utility model, a double-sided machine for producing economical corrugated boxes is provided, which further includes: the outlet pipe is inclined toward the heat-bonding box, and a nozzle is fixedly connected to the bottom end of each outlet pipe.

[0023] The beneficial effects of the embodiments of this utility model are as follows:

[0024] In this utility model, by means of the structural cooperation of the limiting components, the path of corrugated cardboard of different sizes into the heat laminating box can be controlled by adjusting the distance between the two limiting plates, so as to avoid the corrugated cardboard from deviating.

[0025] In this invention, the preheating component, external fan, external pipe and air supply pipe are structurally coordinated to obtain heated gas from the heat bonding box for preheating of corrugated cardboard, making the corrugated cardboard easier to process and reducing overall energy consumption. In addition, with the connection between the flow control rod and the push plate, the airflow outlet range of the flow distribution pipe can be adjusted by the displacement of the flow control plate inside the flow distribution pipe when the limit plate is adjusted, thus avoiding airflow waste.

[0039] like Figures 1-5 As shown, it illustrates a cost-saving double-facer for corrugated cardboard box production according to one embodiment of the present invention.

[0040] In some examples, the heat bonding box 1 and the cooling box 2 are included, with the cooling box 2 fixedly connected to one end of the heat bonding box 1, and the heat bonding box 1 is also included.

[0041] Adjusting cylinder 3 is fixedly connected to the top of the heat bonding box 1 at the end away from the cooling box 2. The output end of adjusting cylinder 3 is fixedly connected to assembly frame 4. The bottom end of assembly frame 4 is provided with limit component 5. Limit component 5 is used to limit the path of corrugated cardboard into heat bonding box 1. A preheating component 6 is provided on one side of assembly frame 4.

[0042] An external exhaust fan 7 is fixedly connected to the top of the heat bonding box 1 near the cooling box 2. An external exhaust pipe 8 is fixedly connected to the input end of the external exhaust fan 7, and the bottom end of the external exhaust pipe 8 extends into the interior of the heat bonding box 1. An air supply pipe 9 is fixedly connected to the output end of the external exhaust fan 7. The air supply pipe 9 is used to cooperate with the preheating component 6 to preheat the corrugated cardboard.

[0043] In this embodiment, the principle of the heat-bonding box 1 and the cooling box 2 can be found in the double-face machine of a corrugated cardboard production line disclosed in CN208469191U. It is a mature existing technology and will not be described in detail here.

[0044] For example, such as Figures 2-4As shown, the limiting component 5 includes:

[0045] Two push rods 10 are slidably connected to both ends of the assembly frame 4. One end of the push rod 10 located inside the assembly frame 4 is fixedly connected to a limit plate 11, and the other end of the push rod 10 located outside the assembly frame 4 is fixedly connected to a push frame 12. The top of the push frame 12 is rotatably connected to a push plate 13.

[0046] The transmission seat 14 is fixedly connected to the top of the assembly frame 4. Both ends of the transmission seat 14 are rotatably connected to the transmission shaft 15. The outer side of the transmission shaft 15 is fixedly connected to the eccentric plate 16 and the linkage spur gear 18. The two linkage spur gears 18 are meshed and connected. The ends of the two push plates 13 away from the push frame 12 are rotatably connected to the ends of the two eccentric plates 16 respectively.

[0047] The drive motor 17 is fixedly connected to one side of the transmission base 14, and the output end of the drive motor 17 is fixedly connected to one of the transmission shafts 15.

[0048] For example, such as Figure 3 As shown, a stabilizing rod is fixedly connected to the inner side of the assembly frame 4, and a stabilizing hole is opened at the top of the limiting plate 11. The stabilizing hole and the stabilizing rod are in clearance fit. By setting the stabilizing rod, the path of the limiting plate 11 can be further limited to ensure the stability of the displacement of the limiting plate 11.

[0049] For example, such as Figure 3 As shown, the top of the pusher frame 12 and one end of the eccentric plate 16 are both fixedly connected to the assembly rods, and the two ends of the pusher plate 13 are respectively rotatably connected to the two assembly rods. By setting the assembly rods, the ends of the pusher plate 13 can be stably supported, ensuring the smoothness of the transmission of the pusher plate 13 between the pusher frame 12 and the eccentric plate 16.

[0050] For example, such as Figure 4 As shown, a protective shell is fixedly connected to the side of the transmission base 14 near the linkage spur gear 18, and the linkage spur gear 18 is located inside the protective shell. By setting the protective shell, the linkage spur gear 18 can be prevented from being directly exposed to dust and other debris, thereby ensuring the stability of the transmission of the linkage spur gear 18.

[0051] For example, such as Figure 5 As shown, the preheating component 6 includes:

[0052] Two extension seats 19 are fixedly connected to both ends of the assembly frame 4, and a diversion pipe 20 is fixedly connected between the two extension seats 19. Multiple outlet pipes 21 are fixedly connected to the bottom end of the diversion pipe 20.

[0053] Two flow control rods 22 are slidably connected to both ends of the diversion tube 20, and the end of the flow control rod 22 near the pusher 12 is fixedly connected to the pusher 12. A flow control plate 23 is fixedly connected to the end of the flow control rod 22 inside the diversion tube 20.

[0054] Transmission pipe 24 is fixedly connected to the middle of the top end of the split pipe 20, and the end of transmission pipe 24 away from the split pipe 20 is also connected to the gas supply pipe 9.

[0055] For example, such as Figure 5 As shown, the outlet pipe 21 is inclined towards the heat bonding box 1. Each outlet pipe 21 is fixedly connected to a nozzle at its bottom end. By setting the nozzle, the airflow entering the outlet pipe 21 can be stably sprayed onto the corrugated cardboard and the blind spot of the outlet pipe 21 can be reduced.

[0056] For example, such as Figure 5 As shown, an observation window is provided on the outside of the diversion tube 20, and a transparent observation plate is fixedly connected inside the observation window. By setting the transparent observation plate, the observation window can be blocked, and the position of the flow control plate 23 inside the diversion tube 20 can be intuitively fed back.

[0057] For example, such as Figure 5 As shown, a sealing ring is fixedly connected to the outer side of the flow control plate 23. The sealing ring and the inner wall of the diversion pipe 20 are in transition fit. By setting the sealing ring, the gap between the flow control plate 23 and the diversion pipe 20 can be sealed, thereby restricting the gas flow inside the diversion pipe 20. At the same time, in order to ensure the application effect of the sealing ring, the material of the sealing ring can be rubber.

[0058] For example, such as Figure 1 As shown, the air supply pipe 9 includes a flexible section and a rigid section. The rigid section is fixedly connected to the output end of the external exhaust fan 7, and the flexible section is fixedly connected to the transmission pipe 24. Due to the material properties of the air supply pipe 9, the assembly frame 4 can be vertically adjusted without affecting the airflow transmission. The top of the heat bonding box 1 is also equipped with multiple stabilizing seats, and the rigid section of the air supply pipe 9 is also installed above the stabilizing seats.

[0059] Working principle: First, the corrugated cardboard is fed into the heat-bonding box 1 through the gap between the two limiting plates 11. During the feeding process, the path of the corrugated cardboard is limited by the limiting plates 11 to prevent the corrugated cardboard from deviating. The external exhaust fan 7 can be started to extract the heated gas inside the heat-bonding box 1 through the external exhaust pipe 8, and inject it into the diversion pipe 20 through the air supply pipe 9 and the transmission pipe 24. Finally, through the diversion of multiple outlet pipes 21, the heated airflow is sprayed onto the corrugated cardboard to preheat it.

[0060] Furthermore, the drive motor 17 can be started to drive the drive shaft 15 connected to it to rotate. With the connection of two linkage spur gears 18, the power of the drive motor 17 can be transmitted so that the two eccentric plates 16 can be driven to rotate synchronously and in opposite directions by means of the two drive shafts 15. Since the push plate 13 is connected between the eccentric plate 16 and the push frame 12, when the eccentric plate 16 rotates, the push plate 13 can pull the push frame 12, causing the push rod 10 to push the limit plate 11 to move, thereby changing the distance between the two limit plates 11 to adapt to different specifications of corrugated cardboard.

[0061] Furthermore, with the flow control rod 22 connected to the pusher frame 12, the flow control rod 22 can follow the displacement of the pusher frame 12 to adjust the position of the flow control plate 23 inside the diversion tube 20. The distance between the two flow control plates 23 is the range within which the airflow inside the diversion tube 20 can be discharged, thus avoiding airflow waste.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
