Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to a uniformly heated paper box production and drying equipment. Background Technology

[0002] A cardboard box is a container made of paper or cardboard, usually in the shape of a cuboid, cube, or other regular geometric shape. It is mainly used to package various items, such as food, medicine, cosmetics, and electronic products, to protect the products, facilitate transportation, and display product information. The most commonly used materials for cardboard boxes are cardboard and corrugated cardboard. Freshly produced cardboard boxes contain a lot of water, so they need to be dried.

[0003] When freshly produced cardboard boxes are dried, they are prone to deformation due to uneven paper thickness and moisture distribution. Furthermore, if the thickness of different parts of the cardboard box is inconsistent or the surface is uneven, different parts will be heated and dried at different rates during the drying process. This may result in some areas of the cardboard box being over-dried while other areas remain damp, thus affecting the drying effect of the cardboard box.

[0004] Therefore, a uniformly heated paper box production drying equipment is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a uniformly heated paper box production drying equipment, which can solve the problem that newly produced paper boxes are prone to deformation during drying due to uneven paper thickness and moisture distribution. Furthermore, if different parts of the paper box have inconsistent thickness or uneven surfaces, different parts will be heated and dried at different degrees during the drying process. This may result in some areas of the paper box being over-dried while other areas remain damp, thus affecting the drying effect of the paper box.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniformly heated paper box production and drying equipment, including a box body, a hot air blower fixedly connected to the top of the box body, a placement component provided inside the box body, the placement component including a placement frame, and a pretreatment component fixedly connected to the front side inside the box body;

[0007] The pretreatment component includes a mounting frame, which is fixedly connected to the inside of the housing. A conveying roller is rotatably connected to the bottom of the mounting frame. A first control motor is fixedly connected to the left side of the conveying roller. A U-shaped frame is provided at the top of the mounting frame. A squeezing roller is rotatably connected inside the U-shaped frame. The squeezing roller works in conjunction with the conveying roller. Grooves are provided on both sides of the inner wall of the mounting frame. A transmission screw is rotatably connected inside the right groove. A threaded sleeve is threaded onto the surface of the transmission screw. The side of the threaded sleeve closest to the U-shaped frame is fixedly connected to the U-shaped frame.

[0008] Preferably, the placement frame is equipped with a mesh belt conveyor, the top of which is flush with the top of the conveyor roller.

[0009] Preferably, a limiting plate is provided inside the placement frame, the limiting plate is located above the mesh belt conveyor and the limiting plate is made of a heat-conducting material.

[0010] Preferably, a fixing block is fixedly connected to the middle of the top of the placement frame, and an electric telescopic rod is fixedly connected inside the fixing block. The telescopic end of the electric telescopic rod is fixedly connected to the top of the limiting plate.

[0011] Preferably, a connecting shaft is fixedly connected to the rear side of the placement frame. The connecting shaft passes through the box body and is rotatably connected to the box body. A driven gear is fixedly connected to one end of the connecting shaft located on the outside of the box body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application sets up a pre-treatment component, which, through the cooperation of the extrusion roller and the conveyor roller, can extrude the paper box, effectively removing wrinkles and uneven parts generated during the production process. This makes the paper box more even in shape, and the evenly heated paper box can avoid local overheating or insufficient heating, thereby ensuring that the moisture inside the paper box can evaporate evenly, thus improving the drying effect.

[0017] 2. This application, through the setting of placement components, ensures that the top of the mesh belt conveyor is flush with the top of the conveyor roller, allowing the cartons to continuously and stably enter the mesh belt conveyor. The limiting plate can accurately position the cartons in the required position, thus enabling multiple cartons to be dried simultaneously. The mesh belt conveyor has good air permeability, allowing hot air to circulate freely through the mesh holes of the mesh belt at the bottom of the cartons. This avoids uneven drying caused by heat accumulation or ineffective heating at the bottom of the cartons, ensuring that all parts of the cartons receive heat evenly, further optimizing the drying effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A uniformly heated paper box production and drying equipment includes a box body 1, a hot air blower 2 fixedly connected to the top of the box body 1, a placement component 3 provided inside the box body 1, the placement component 3 including a placement frame 301, and a pretreatment component 4 fixedly connected to the front side inside the box body 1.

[0028] The pretreatment component 4 includes a mounting frame 401, which is fixedly connected to the inside of the housing 1. A conveying roller 402 is rotatably connected to the bottom of the mounting frame 401. A first control motor 403 is fixedly connected to the left side of the conveying roller 402. A U-shaped frame 404 is provided at the top inside the mounting frame 401. A pressing roller 405 is rotatably connected inside the U-shaped frame 404. The pressing roller 405 works in conjunction with the conveying roller 402. Grooves 406 are provided on both sides of the inner wall of the mounting frame 401. A transmission screw 407 is rotatably connected inside the right groove 406. A threaded sleeve 408 is threaded onto the surface of the transmission screw 407. The side of the threaded sleeve 408 closest to the U-shaped frame 404 is fixedly connected to the U-shaped frame 404.

[0029] In this embodiment: by setting the pretreatment component 4, the first control motor 403 can drive the conveyor roller 402 to rotate. When the paper box is placed on top of the conveyor roller 402, the paper box will move forward with the rotation direction of the conveyor roller 402. When the paper box moves to the corresponding position below the extrusion roller 405, the operator can manually rotate the transmission screw 407 according to the actual situation of the paper box. When the transmission screw 407 rotates, the screw sleeve 408 and the U-shaped frame 404 will move along the axial direction of the transmission screw 407, so that the extrusion roller 405 moves closer to or further away from the conveyor roller 402. After adjusting to a suitable distance, the extrusion roller 405 will apply a certain pressure to the paper box being conveyed, and extrude and flatten the paper box. As the paper box continues to move forward under the drive of the conveyor roller 402, continuous extrusion of the entire surface of the paper box can be achieved, so that the paper box reaches a relatively flat state after this pretreatment process, which is ready for uniform heating and drying in the subsequent drying equipment.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, a mesh belt conveyor 302 is installed inside the placement frame 301, and the top of the mesh belt conveyor 302 is flush with the top of the conveyor roller 402.

[0031] Specifically, such as Figure 4 As shown, a limiting plate 303 is provided inside the placement frame 301. The limiting plate 303 is located above the mesh belt conveyor 302 and is made of a heat-conducting material.

[0032] Specifically, such as Figure 4 As shown, a fixing block 304 is fixedly connected to the middle of the top of the placement frame 301, and an electric telescopic rod 305 is fixedly connected inside the fixing block 304. The telescopic end of the electric telescopic rod 305 is fixedly connected to the top of the limiting plate 303.

[0033] In this embodiment: With the above settings, the cardboard box can smoothly transition from the pretreatment component 4 to the top of the mesh belt conveyor 302. The mesh structure of the mesh belt facilitates the circulation of hot air at the bottom of the cardboard box, allowing the bottom of the cardboard box to be heated evenly, thereby improving drying efficiency and reducing drying time. The limiting plate 303 can play a precise positioning role during the cardboard box conveying process. When it is necessary to limit the cardboard box, the electric telescopic rod 305 drives the limiting plate 303 to move downward, so that it contacts the cardboard box and prevents the cardboard box from moving forward. This ensures that the cardboard box is in the right position and improves the stability during drying. At the same time, the limiting plate 303 is made of thermally conductive material, which can transfer heat when in contact with the cardboard box, promote the evaporation of moisture on the top of the cardboard box, and further improve the drying effect.

[0034] Specifically, such as Figure 6 As shown, a connecting shaft 5 is fixedly connected to the rear side of the placement frame 301. The connecting shaft 5 passes through the box 1 and is rotatably connected to the box 1. A driven gear 6 is fixedly connected to one end of the connecting shaft 5 located on the outside of the box 1.

[0035] Specifically, such as Figure 6 As shown, a drive box 7 is fixedly connected to the rear side of the housing 1, and one end of the connecting shaft 5 extends into the interior of the drive box 7 and is rotatably connected to the drive box 7. A second control motor 8 is fixedly connected inside the drive box 7. A transmission shaft 9 is fixedly connected to the output end of the second control motor, and the side of the transmission shaft 9 near the housing 1 is rotatably connected to the housing 1. A drive gear 10 is fixedly sleeved on the surface of the transmission shaft 9, and the drive gear 10 meshes with the driven gear 6.

[0036] In this embodiment: With the above settings, the second control motor 8 can drive the transmission shaft 9 and the drive gear 10 to rotate. When the drive gear 10 rotates, it will drive the driven gear 6 to rotate. When the driven gear 6 rotates, it will drive the connecting shaft 5 and the placement frame 301 to rotate synchronously. This allows the cardboard box to change its angle during the drying process. This ensures that all sides of the cardboard box can fully contact the hot air blown out by the hot air blower, avoiding uneven heating in some areas that may occur due to the fixed position of the cardboard box, and further improving the uniformity of drying.

[0037] Specifically, such as Figure 5 As shown, a slider 11 is fixedly connected to the left side of the U-shaped frame 404, and the slider 11 is slidably connected inside the left groove 406.

[0038] Specifically, such as Figure 1 , Figure 2As shown, a door 12 is rotatably connected to the front of the box 1, and the box 1 is made of transparent acrylic sheet.

[0039] In this embodiment: by setting slider 11, which is slidably connected to the left groove 406, additional support and guidance can be provided for U-shaped frame 404, avoiding instability such as offset and swaying during movement of U-shaped frame 404, so that the distance between squeeze roller 405 and conveyor roller 402 can be adjusted accurately and stably. By setting box door 12, the transparent acrylic box 1 can make it easy for operators to see the real-time drying status of the paper box in the box 1.

[0040] Working principle: When drying the cardboard boxes, first open the door 12 and place the cardboard box on top of the conveyor roller 402. Then, rotate the drive screw 407. When the drive screw 407 rotates, the screw sleeve 408 and the U-shaped frame 404 will move axially along the drive screw 407, thereby bringing the squeeze roller 405 closer to the conveyor roller 402. After adjusting to a suitable distance, the squeeze roller 405 will apply a certain pressure to the cardboard box being conveyed, squeezing and flattening the cardboard box. Then, relying on the friction generated by the rotation of the conveyor roller 402, the cardboard box will move along the conveyor roller 402 to the top of the mesh belt conveyor 302. Then, start the hot air blower 2, which will blow hot air into the box 1. When multiple cardboard boxes move to the appropriate position on the mesh belt conveyor 302, the electric telescopic rod 305 can drive the limit plate 303 to move downward until the limit plate 303 contacts the cardboard box and... The limiting plate 303 prevents the cardboard box from moving forward. Upon contact with the cardboard box, the limiting plate 303 transfers heat to the cardboard box, heating the upper part of the cardboard box and promoting the evaporation of moisture. At this time, the upper and lower parts of the cardboard box are dried more evenly under the combined action of hot air and the heat conduction of the limiting plate 303. At the same time, the second control motor 8 is started, and its output end drives the transmission shaft 9 and the drive gear 10 to rotate together. The drive gear 10 drives the driven gear 6 to mesh and the connecting shaft 5 to rotate, thereby causing the placement frame 301 to rotate around the axis of the connecting shaft 5. The rotation of the placement frame 301 causes the cardboard box to continuously change its angle during the drying process, so that all surfaces of the cardboard box can fully and evenly receive the hot air blown out by the hot air blower 2, further improving the drying efficiency and quality. After drying is completed, the limiting plate 303 is released, and the dried cardboard box is then transported out of the box 1 by the mesh belt conveyor 302 and the conveyor roller 402.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
