Description

Technical Field

[0001] This utility model relates to the field of packaging box drying, and in particular to drying equipment for packaging box production. Background Technology

[0002] In the production of packaging cartons, wet cartons after printing, lamination, or gluing processes need to be quickly dried using drying equipment to remove surface moisture and ensure the cartons' forming strength. Existing drying equipment often employs methods such as hot air circulation, infrared radiation, or microwave heating, with cartons continuously transported via conveyor belts to complete the drying process.

[0003] However, traditional drying equipment faces significant technical bottlenecks in practical applications. Existing drying equipment primarily relies on hot air convection or radiation heating for heat transfer, with the heat primarily affecting the top and sides of the cartons. Since the bottom of the cartons is in direct contact with the conveyor belt, heat cannot effectively penetrate the bottom. Insufficient drying at the bottom can lead to warping and collapse of the cartons during stacking or storage due to residual moisture. Based on this, we propose a drying equipment for packaging box production. Utility Model Content

[0004] To solve the technical problem of the inability to dry the bottom of cardboard boxes, this utility model provides a drying device for packaging box production.

[0005] This utility model is achieved by the following technical solution: a drying equipment for packaging box production, including a conveying mechanism support, a positioning mechanism support integrally welded on the conveying mechanism support, a conveying roller assembly installed at the bottom of the conveying mechanism support, and a packaging box positioning mechanism installed on the inner side of the positioning mechanism support.

[0006] The packaging box positioning mechanism includes a fixed base, which is fixedly connected to the inner side of the positioning mechanism bracket. An electric push rod is installed on the fixed base. The output end of the electric push rod is connected to a mounting platform plate. A hydraulic cylinder is fixedly connected to the surface of the mounting platform plate. A sleeve-shaped piston rod is connected to the output end of the hydraulic cylinder. A connecting block is connected to the top of the sleeve-shaped piston rod. A clamping claw is fixedly connected to the bottom surface of the connecting block.

[0007] The hydraulic cylinder is a bidirectional drive cylinder, with two sets of sleeve-shaped piston rods connected to both ends of the hydraulic cylinder. A sliding block is connected to the bottom surface of the mounting platform plate, and the sliding block is slidably engaged with the surface of the sliding frame. The sliding frame is fixedly mounted on the surface of the positioning mechanism bracket.

[0008] After the clamping claws grip the carton, the electric push rod on the positioning mechanism bracket drives the mounting platform plate to move longitudinally, the sliding block slides along the sliding frame, and the electric push rod slightly lifts the carton so that its bottom forms a gap with the surface of the conveyor roller assembly.

[0009] A drying assembly is installed at the bottom of the positioning mechanism support. The drying assembly includes a drying dish and a heating element tube. The drying dish is installed above the edge of the conveying mechanism support, and the heating element tube is installed around the inside of the drying dish. There are two sets of drying assemblies, which are installed opposite each other and cover both sides of the clamping claw.

[0010] As a further optimization of this utility model, the drying dish is in the shape of a rectangular groove to avoid heat loss. The rectangular groove structure of the drying dish reduces heat loss, and the surrounding layout of the heating element tubes ensures uniform heat distribution.

[0011] As a further optimization of this utility model, the top and side facades of the carton are dried by environmental heat flow circulation. The bidirectional drive function of the electric push rod can dynamically adjust the height of the carton to adapt to the drying needs of cartons of different thicknesses, ensuring that the bottom gap is always in the best state of heat flow penetration.

[0012] As a further optimization of this utility model, two sets of oppositely installed drying components are started simultaneously. The heating component tube heats the inside of the drying dish to the set temperature. The heat is concentrated and radiated to the gap area at the bottom of the carton through the rectangular groove-shaped drying dish. At the same time, the heat flow penetrates the bottom of the carton from both sides through the gap and acts directly on the bottom surface of the carton.

[0013] As a further optimization of this utility model, the carton is transported to the drying station by the conveyor roller assembly along the conveyor mechanism support. The hydraulic cylinder drives the connecting block and clamping claws to laterally clamp the two sides of the carton through the sleeve-shaped piston rod, ensuring that the carton is centered and positioned to avoid displacement.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses an electric push rod to drive the clamping claws to slightly lift the carton, so that the bottom of the carton forms a gap with the conveyor roller assembly. With the drying components installed symmetrically on both sides, the heat flow can directly penetrate the gap area at the bottom of the carton, which significantly improves the drying effect at the bottom and avoids problems such as warping and collapse caused by local moisture residue.

[0016] 2. The drying dish of this utility model adopts a rectangular groove structure, combined with a heating component tube with a surrounding layout, which effectively reduces heat loss, ensures that the heat is evenly distributed and concentrated on the bottom of the carton, improves the efficiency of heat utilization, and reduces energy consumption costs.

[0017] 3. The coordinated control of the hydraulic cylinder and electric push rod of this utility model can dynamically adjust the carton clamping height and gap size, adapt to the drying process requirements of cartons of different thicknesses, ensure that the bottom gap is always in the best heat flow penetration state, and enhance the versatility of the equipment.

[0018] 4. This utility model dries the top and side surfaces through environmental heat flow circulation and the bottom through directional heat flow penetration. Combined with the concentrated heat radiation from the rectangular trough-shaped drying dish, it achieves synchronous and uniform drying of the entire surface of the carton, improving the consistency of finished product quality.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example 1: Please refer to Figures 1-4 This embodiment proposes a drying equipment for packaging box production, including a conveying mechanism support 1, a positioning mechanism support 2 integrally welded on the conveying mechanism support 1, a conveying roller assembly 3 installed at the bottom end of the conveying mechanism support 1, and a packaging box positioning mechanism 4 installed on the inner side of the positioning mechanism support 2. The conveying roller assembly 3 is a commonly used conveying roller structure in the market and belongs to the prior art.

[0027] The packaging box positioning mechanism 4 includes a fixed base 41, which is fixedly connected to the inner side of the positioning mechanism bracket 2. An electric push rod 42 is installed on the fixed base 41. The output end of the electric push rod 42 is connected to a mounting platform plate 43. A hydraulic cylinder 44 is fixedly connected to the surface of the mounting platform plate 43. A sleeve-shaped piston rod 45 is connected to the output end of the hydraulic cylinder 44. A connecting block 46 is connected to the top of the sleeve-shaped piston rod 45. A clamping claw 47 is fixedly connected to the bottom surface of the connecting block 46.

[0028] Furthermore, the hydraulic cylinder 44 is a bidirectional drive cylinder, and two sets of sleeve-shaped piston rods 45 are provided, with the two sets of sleeve-shaped piston rods 45 connected to both ends of the hydraulic cylinder 44.

[0029] Specifically, the cartons are transported to the drying station by the conveyor roller assembly 3 along the conveyor mechanism bracket 1. The hydraulic cylinder 44 drives the connecting block 46 and the clamping claw 47 to laterally clamp the two sides of the carton through the sleeve-shaped piston rod 45, ensuring that the carton is centered and preventing it from shifting.

[0030] The bottom surface of the mounting platform plate 43 is connected to a sliding block 48, which slides and engages with the surface of the sliding frame 49. The sliding frame 49 is fixedly mounted on the surface of the positioning mechanism bracket 2.

[0031] More specifically, after the clamping claw 47 clamps the carton, the electric push rod 42 on the positioning mechanism bracket 2 drives the mounting platform plate 43 to move longitudinally, the sliding block 48 slides along the sliding frame 49, and the electric push rod 42 slightly lifts the carton so that its bottom forms a gap with the surface of the conveyor roller assembly 3.

[0032] Two sets of oppositely installed drying components 5 start synchronously. The heating component tube 52 heats the inside of the drying dish 51 to the set temperature. The heat is concentrated and radiated to the gap area at the bottom of the carton through the rectangular groove-shaped drying dish 51. At the same time, the heat flow penetrates the bottom of the carton from both sides through the gap and acts directly on the bottom surface of the carton.

[0033] The top and side surfaces of the carton are dried through ambient heat circulation. The bidirectional drive function of the electric push rod 42 can dynamically adjust the height of the carton to adapt to the drying needs of cartons of different thicknesses, ensuring that the bottom gap is always in the best state of heat flow penetration.

[0034] A drying component 5 is installed at the bottom of the positioning mechanism support 2. The drying component 5 includes a drying dish 51 and a heating component tube 52. The drying dish 51 is installed above the edge of the conveying mechanism support 1, and the heating component tube 52 is installed around the inside of the drying dish 51.

[0035] It should be noted that there are two sets of drying components 5, which are installed opposite each other and cover both sides of the clamping claw 47.

[0036] Furthermore, the drying dish 51 is rectangular in shape to prevent heat loss. The rectangular groove structure of the drying dish 51 reduces heat loss, and the surrounding layout of the heating element tubes 52 ensures uniform heat distribution.

[0037] This drying equipment for packaging box production achieves uniform drying of cartons from all directions through coordinated control of conveying, positioning, and drying components. It offers an innovative solution, particularly addressing the challenge of drying the bottom. The specific workflow is as follows:

[0038] Carton conveying and positioning

[0039] The cartons are transported to the drying station by the conveyor roller assembly 3 along the conveyor support 1. The hydraulic cylinder 44 drives the connecting block 46 and the clamping claw 47 to laterally clamp the two sides of the carton through the sleeve-shaped piston rod 45, ensuring that the carton is centered and preventing it from shifting.

[0040] Bottom gap formation and hot air penetration

[0041] After the clamping claw 47 clamps the carton, the electric push rod 42 on the positioning mechanism bracket 2 drives the mounting platform plate 43 to move longitudinally, the sliding block 48 slides along the sliding frame 49, and the electric push rod 42 slightly lifts the carton so that its bottom forms a gap with the surface of the conveyor roller assembly 3.

[0042] Two sets of oppositely installed drying components 5 start synchronously. The heating component tube 52 heats the inside of the drying dish 51 to the set temperature. The heat is concentrated and radiated to the gap area at the bottom of the carton through the rectangular groove-shaped drying dish 51. At the same time, the heat flow penetrates the bottom of the carton from both sides through the gap and acts directly on the bottom surface of the carton.

[0043] Even drying

[0044] The rectangular groove structure of the drying dish 51 reduces heat loss, and the surrounding layout of the heating element tubes 52 ensures uniform heat distribution.

[0045] The top and side surfaces of the carton are dried through ambient heat circulation. The bidirectional drive function of the electric push rod 42 can dynamically adjust the height of the carton to adapt to the drying needs of cartons of different thicknesses, ensuring that the bottom gap is always in the best state of heat flow penetration.
