Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, and in particular to a dewaxing and drying device for cardboard box production. Background Technology

[0002] In the production of cardboard boxes, dewaxing and drying is an important process. Dewaxing and drying can improve printing activity, ensure clear printing patterns and color fastness. After dewaxing and drying, the paper fibers are tightly bound again, restoring the structural strength of corrugated paper (such as edge crush strength and bursting strength), and preventing deformation and damage during transportation.

[0003] In some small factories, there are some shortcomings in the dewaxing and drying process of cardboard boxes. For example, in the material handling stage, most existing equipment relies on manual feeding. Operators need to stay at the feeding port for a long time and manually place the cardboard sheets one by one onto the conveyor belt. Similarly, in the receiving stage, it is necessary to have a dedicated person at the receiving port to collect and sort the dried cardboard sheets. This traditional manual intervention mode not only increases the workload of operators, but also has the problem of low production efficiency. Therefore, we urgently need a dewaxing and drying device for cardboard box production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of long drying time and low drying efficiency caused by using a flat conveyor belt in the prior art, and to propose a dewaxing and drying device for carton production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dewaxing and drying device for carton production includes a conveyor belt driven by an external drive unit and a dryer installed in the middle of the conveyor belt. It also includes: a material feeding rod installed on the conveyor belt; a receiving box installed at the feed end of the conveyor belt, the bottom wall of which has symmetrically formed rectangular channels adapted to the material feeding rod; two sets of rectangular through holes symmetrically formed on the receiving box; a first support plate slidably connected to the receiving box in the lower rectangular through hole; and a second support plate slidably connected to the receiving box in the upper rectangular through hole. When the two sets of support plates 1 and 2 abut against each other, a placement area is formed.

[0007] The receiving section is installed at the discharge end of the conveyor belt.

[0008] To support the carton, preferably, an electric guide rail is fixedly connected to the receiving box at the position corresponding to the lower rectangular through hole. The output end of the electric guide rail is fixedly connected to the support plate. When the electric guide rail is working, the two sets of corresponding support plates move closer or further apart.

[0009] To support cartons of different sizes, preferably, an electric push rod is fixedly connected to the receiving box above the rectangular through hole. The output end of the electric push rod is fixedly connected to an electric guide rail two. The output end of the electric guide rail two is fixedly connected to a support plate two. When the electric push rod is working, the support plate two moves up and down within the rectangular through hole. When the electric guide rail two is working, the two sets of support plates two move closer to or further away from each other.

[0010] To facilitate the movement of the second support plate, the area ratio of the upper rectangular through hole to the lower rectangular through hole is 2:1.

[0011] For convenient material collection, preferably, the receiving part includes a receiving platform located at the discharge end of the conveyor belt. The receiving plate on the receiving platform is in contact with the conveyor belt. An opening slot is provided on the receiving platform. Elastic support members are symmetrically installed on the bottom wall of the opening slot. A placement plate is fixedly connected to the end of the elastic support member.

[0012] To prevent the cardboard from falling, the receiving section further includes a baffle one hinged to the receiving platform, the baffle one abutting against the side of the receiving platform away from the conveyor belt, and baffle two symmetrically installed on the receiving platform.

[0013] To further limit the position of the baffle, a limiting pin is provided on the baffle, and a limiting hole coaxial with the limiting pin is provided on the receiving platform. When the baffle abuts against the receiving platform, the limiting pin is inserted into the limiting hole.

[0014] Compared with the prior art, this utility model provides a dewaxing and drying device for carton production, which has the following beneficial effects:

[0015] 1. This dewaxing and drying device for carton production, through the setting of support plate one and support plate two, allows operators to place stacks of cardboard on the placement area formed by the two sets of support plates one. Based on the cardboard thickness, the height of support plate two is adjusted by an electric push rod, and then driven by electric guide rail two, support plate two is pushed inward, separating the cardboard. At this time, the stacked cardboard is located on the placement area formed by support plate two, and individual cardboard pieces are located on the placement area formed by support plate one. Then, electric guide rail one drives support plate one to retract backward, causing individual cardboard pieces to fall downward to the bottom of the receiving box. Waiting for the material-pulling rod on the conveyor belt to move onto the conveyor belt, support plate one resets, support plate two opens, and the stacked cardboard is moved back to the placement area formed by support plate one. Repeating the above operation achieves the feeding of cartons, effectively adapting to different cardboard thicknesses, increasing the feeding speed, reducing manual labor, and improving feeding accuracy.

[0016] 2. This dewaxing and drying device for carton production, through the setting of the receiving section, can uniformly collect the dried cardboard and complete the sorting of the cardboard during the collection process, effectively improving the collection efficiency.

[0017] 3. The dewaxing and drying device for carton production, through the setting of the feeding rod, when the conveyor belt drives the feeding rod to move, the feeding rod enters the rectangular channel, which can push the individual carton located on the bottom wall of the receiving box and push it onto the conveyor belt. This improves the previous situation where manual placement was required, thereby effectively improving the feeding efficiency and reducing the workload of operators.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model effectively improves drying efficiency, saves the workload of operators, and can sort the dried cardboard during discharge. Attached Figure Description

[0026] Example:

[0027] Reference Figures 1-4 A dewaxing and drying apparatus for cardboard box production includes a conveyor belt 1 driven by an external drive unit and a dryer 2 installed in the middle of the conveyor belt 1. Here, the dryer 2 is a common drying device, such as a microwave dryer, which needs to be electrically connected to an external power supply and controller to start up, providing the necessary drying temperature for the cardboard boxes. It also includes:

[0028] A feeding rod 19 is installed on the conveyor belt 1, and a receiving box 3 is installed at the feeding end of the conveyor belt 1. The bottom wall of the receiving box 3 is symmetrically provided with rectangular channels 4 adapted to the feeding rod 19. Here, when the conveyor belt 1 drives the feeding rod 19 to move, the feeding rod 19 enters the rectangular channel 4, which can push the individual carton located on the bottom wall of the receiving box 3 and push it onto the conveyor belt 1. This improves the previous situation where manual placement was required, thereby effectively improving the feeding efficiency and reducing the workload of operators.

[0029] Two sets of rectangular through holes 5 are symmetrically opened on the receiving box 3. The area ratio of the upper rectangular through hole 5 to the lower rectangular through hole 5 is 2:1. Here, the larger rectangular through hole 5 is used to adjust different cardboard thicknesses, thus adapting to different cardboard thicknesses. A support plate 6 is slidably connected to the receiving box 3 within the lower rectangular through hole 5. A second support plate 7 is raised and slidably connected to the receiving box 3 within the upper rectangular through hole 5. When the two sets of support plates 6 and 7 are abutted, a placement area is formed. An electric guide rail 8 is fixedly connected to the receiving box 3 at the position corresponding to the lower rectangular through hole 5. The output end of the electric guide rail 8 is fixedly connected to the support plate 6. When the electric guide rail 8 is working, the two sets of corresponding support plates 6 move closer or further apart. An electric push rod 9 is fixedly connected to the receiving box 3 above the upper rectangular through hole 5. The output end of the electric push rod 9 is fixedly connected to the electric guide rail 10. The output end of the electric guide rail 10 is fixedly connected to the support plate 7. When the electric push rod 9 is working, the electric push rod 9 moves closer or further apart. When the push rod 9 is working, the support plate 2 7 moves up and down in the rectangular through hole 5. When the electric guide rail 2 10 is working, the two sets of support plates 2 7 move closer or further apart. Here, the operator places a pile of cardboard on the placement area formed by the two sets of support plates 1 6. According to the thickness of the cardboard, the height of the support plate 2 7 is adjusted by the electric push rod 9. Then, the support plate 2 7 is pushed inward by the electric guide rail 2 10 and the cardboard is separated. At this time, the piled cardboard is located on the placement area formed by the support plate 2 7, and the single cardboard is located on the placement area formed by the support plate 1 6. At this time, the electric guide rail 1 8 drives the support plate 1 6 to retract backward, so that the single cardboard falls down to the bottom of the receiving box 3. Wait for the material push rod 19 on the conveyor belt 1 to move onto the conveyor belt 1. At this time, the support plate 1 6 is reset, the support plate 2 7 is opened, and the piled cardboard is moved back to the placement area formed by the support plate 1 6. Repeating the above operation can realize the feeding of the carton. It should be noted that the carton is in a flat and folded state.

[0030] A receiving section is installed at the discharge end of conveyor belt 1. The receiving section includes a receiving platform 11 located at the discharge end of conveyor belt 1. The receiving plate on the receiving platform 11 contacts the conveyor belt 1. An opening slot 12 is provided on the receiving platform 11. Elastic support members 13 are symmetrically installed on the bottom wall of the opening slot 12. A placement plate 14 is fixedly connected to the end of the elastic support member 13. Here, the elastic support member 13 is mainly composed of a sleeve, a sliding rod, and a spring. The sliding rod slides inside the sleeve, and the spring is sleeved outside the sleeve, with its two ends abutting against the bottom wall of the opening slot 12 and the placement plate 14, respectively. When the cardboard moves onto the placement plate 14, as the quantity increases, the gravity increases, and the placement plate 14 moves downward through the sliding rod. When the placement plate 14 moves to its maximum position, it represents the maximum weight that the placement plate 14 can hold. Because the cardboard is relatively light, the spring stiffness is small, which can provide downward pressure, thereby... The placement plate 14 is offset from the receiving platform 11 to facilitate subsequent material collection. The receiving part also includes a baffle 15 hinged to the receiving platform 11. The baffle 15 abuts against the side of the receiving platform 11 away from the conveyor belt 1. A baffle 2 16 is symmetrically installed on the receiving platform 11. A limit pin 17 is provided on the baffle 15, and a limit hole 18 coaxial with the limit pin 17 is opened on the receiving platform 11. When the baffle 15 abuts against the receiving platform 11, the limit pin 17 is inserted into the limit hole 18. At this point, the baffle 15 and the baffle 2 16 act to block the cardboard, preventing the cardboard from moving out of the receiving platform 11. When the operator pulls the limit pin 17 out of the limit hole 18, the baffle 15 flips over, and the operator can collect the material. This allows the dried cardboard to be stacked uniformly, which is convenient for subsequent material collection work, thereby improving work efficiency.

[0031] In this invention, the operator places a stack of cardboard on a placement area consisting of two sets of support plates 6. Based on the cardboard thickness, the height of the second support plate 7 is adjusted using an electric push rod 9. Then, the second support plate 7 is pushed inwards by an electric guide rail 10, separating the cardboard. At this point, the stacked cardboard is positioned on the placement area formed by the second support plate 7, while individual cardboard pieces are positioned on the placement area formed by the first support plate 6. The electric guide rail 8 then drives the first support plate 6 to retract backwards, causing the individual cardboard pieces to fall downwards to the bottom of the receiving box 3. The operator waits for the material-pulling rod 19 on the conveyor belt 1 to move onto the conveyor belt 1. At this point, the first support plate 6 resets, and the support... When support plate 2 7 is opened, the stacked cardboard is moved back to the placement area formed by support plate 1 6. Repeating the above operation can realize the feeding of the carton. After the cardboard is dried by the conveyor belt 1 through the dryer area, it enters the placement plate 14. As the cardboard is accumulated, the placement plate 14 will squeeze the elastic support member 13, causing the placement plate 14 to fall continuously. When the maximum stroke of the elastic support member 13 is reached, the operator pulls out the limit pin 17 and folds the baffle 15 to collect the stacked cardboard. After collection, the baffle 15 is reset. During the material collection, the conveyor belt 1 is in a stopped state.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
