Description

Technical Field

[0001] This utility model belongs to the field of packaging foam drying technology, and specifically relates to a packaging foam drying device. Background Technology

[0002] Nowadays, foam is used more and more widely in packaging, electronics, construction and plastic molding. After the foam is molded, it often needs to be dried, which requires the use of drying equipment.

[0003] Currently, when using packaging foam drying equipment, uneven drying is easily caused when conveying packaging foam with different widths. This is because the distance between the left and right sides of the foam and the hot air drying source cannot be flexibly adjusted, and the position of the hot air nozzle is fixed. For narrow foam, the sides are not dried thoroughly because they are far from the hot air source; while the edges of wide foam are easily overheated because they are close to the fixed hot air source. This uneven hot air action caused by the difference in width directly affects the drying consistency of foam products of different specifications. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a packaging foam drying device. This device aims to solve the problem of uneven drying when conveying packaging foam with varying widths. The distance between the left and right sides of the foam and the hot air drying source cannot be flexibly adjusted, and the hot air nozzle position is fixed, easily leading to uneven drying. Specifically, for narrow foam, the sides are not thoroughly dried because they are far from the hot air source; while the edges of wide foam are easily overheated because they are close to the fixed hot air source. This uneven hot air action caused by width differences directly affects the drying consistency of foam products of different specifications.

[0014] (3) Beneficial effects

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

[0016] This invention allows workers to intermittently place packaging foam of the same batch onto a conveyor belt, which then transports it sequentially. Workers can adjust the positions of the first hot air frame and a pair of second hot air frames according to the height and width of the packaging foam. Height adjustment involves activating an electric push rod, causing its extended end to raise or lower the connecting frame and the first hot air frame. Width adjustment involves activating a first drive motor, causing the transmission rod and its surrounding gears to rotate. This rotates the rack guides on both sides, which mesh with the gears, along with their respective fixed blocks at their ends, guided by guide grooves. Consequently, the second hot air frames positioned below the corresponding fixed blocks also shift relative to each other, adjusting the two second hot air frames to accommodate the width of the packaging foam. Workers then activate the hot air blower. The hot air source for the first hot air frame is provided by a connecting pipe and a first telescopic air duct, while the hot air source for the two second hot air frames is provided through a connecting pipe, a branch pipe, and two second telescopic air ducts, thus coordinating with the first adjustment component to achieve drying treatment at different locations.

[0017] When the second drive motor is started, the packaging foam placed above can be transported sequentially through the conveyor belt with the cooperation of two conveyor rollers and the conveyor belt. The lifting rollers set in the middle of the conveyor belt can effectively prevent the conveyor belt from sagging, thereby ensuring that the conveying process is stable. Attached Figure Description

[0025] This specific embodiment is a packaging foam drying device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the assembly includes a base frame 1, an assembly box 2 fixedly mounted on top of the base frame 1, and an adjustable drying mechanism 3 jointly mounted on the top and middle of the assembly box 2. A conveying mechanism 4 is installed in the middle of the base frame 1. The adjustable drying mechanism 3 includes a hot air blower 31, which is fixedly installed on one side of the top of the assembly box 2. A first adjusting component 32 is mounted on one side of the middle of the assembly box 2. The first adjusting component 32 includes an electric push rod 321, and the extended end of the electric push rod 321 is connected to a connecting frame 322. A first hot air frame 323 is installed below the connecting frame 322, and a first telescopic air duct 325 is connected to the upper input end of the first hot air frame 323. A connecting pipe 324 is connected to the output end of the hot air blower 31. The connecting pipe 324 is connected to the first telescopic air duct 325. The air ducts 325 are interconnected, and a diversion pipe 33 is connected to one side of the connecting pipe 324. A second adjustment component 34 is installed on the other side of the middle of the assembly box 2. The second adjustment component 34 includes a fixed frame 341, which is fixed to the upper side inside the assembly box 2. A fixing block 342 is fixed to the middle of the bottom end of the fixed frame 341, and a transmission rod 343 is installed at the middle of the upper part of the fixing block 342. A first drive motor 344 is installed at one end of the transmission rod 343, and a gear 345 is fixed around the periphery of the transmission rod 343. A rack guide 346 meshes with both sides of the gear 345, and a connecting block 347 is fixed to the end of each of the two rack guides 346. A second hot air frame 349 is fixed below the two connecting blocks 347. The bottom sides of the fixed frame 341 are provided with guide grooves 348, which are connected to the rack and pinion guide 346 for movable guidance. The upper input ends of the two second hot air frames 349 are connected to the second telescopic air ducts 3410. The ends of the second telescopic air ducts 3410 connected to the upper part of the second hot air frames 349 are connected to one of the two output ends of the diversion pipe 33. The staff can intermittently place the same batch of packaging foam on the conveyor belt 43, which will transport them sequentially. Then, the staff can adjust the position of the first hot air frame 323 and the pair of second hot air frames 349 according to the height and width of the packaging foam. The height adjustment method is as follows: the staff starts An electric push rod 321 extends to raise and lower the connecting frame 322 and the first hot air frame 323. For width adjustment, the operator starts the first drive motor 344, causing the transmission rod 343 and its surrounding fixed gears 345 to rotate. This causes the rack guides 346 on both sides, meshing with the gears 345, to move along with their respective fixed connecting blocks 347, guided by the guide grooves 348. Consequently, the second hot air frames 349, located below the corresponding fixed connecting blocks 347, move relative to each other, adjusting the two second hot air frames 349 to accommodate the width of the packaging foam. Afterwards, the operator starts the hot air blower 31. The hot air source for the first hot air frame 323 is provided by the connecting pipe 324 and the first telescopic air duct 325.The hot air sources for the two second hot air frames 349 are supplied through connecting pipe 324, diversion pipe 33, and two second telescopic air ducts 3410, thereby cooperating with the first adjusting component 32 to achieve drying treatment at different locations.

[0026] The conveying mechanism 4 includes two conveying rollers 41, which are respectively located on both sides of the middle part of the base frame 1. One end of one of the conveying rollers 41 is equipped with a second drive motor 42, and the periphery of the two conveying rollers 41 is equipped with a conveying mesh belt 43. The middle part of the base frame 1 is equipped with a lifting roller 44. When the second drive motor 42 is started by the personnel, the packaging foam placed above can be conveyed sequentially through the conveying mesh belt 43 with the cooperation of the two conveying rollers 41 and the conveying mesh belt 43. The lifting roller 44 located in the middle of the conveying mesh belt 43 can effectively prevent the conveying mesh belt 43 from sagging, thereby ensuring that the conveying process is stable.

[0027] Working principle: Workers can intermittently place packaging foam of the same batch on the conveyor belt 43, which will then transport them sequentially. Workers can adjust the positions of the first hot air frame 323 and a pair of second hot air frames 349 according to the height and width of the packaging foam. Height adjustment is achieved by activating the electric push rod 321, causing its extended end to raise or lower the connecting frame 322 and the first hot air frame 323. Width adjustment is achieved by activating the first drive motor 344, which rotates the transmission rod 343 and the gears 345 fixed around it. This causes the racks on both sides meshing with the gears 345 to rotate. The guide frame 346, along with its fixed end block 347, moves in coordination with the guide groove 348. Consequently, the second hot air frames 349, located below the corresponding fixed block 347, also move relative to each other. This allows the two second hot air frames 349 to be adjusted to accommodate the width of the packaging foam. Afterward, the operator starts the hot air blower 31. The hot air source for the first hot air frame 323 is provided by the connecting pipe 324 and the first telescopic air duct 325, while the hot air source for the two second hot air frames 349 is provided through the connecting pipe 324, the diversion pipe 33, and the two second telescopic air ducts 3410 for alignment. This, in conjunction with the first adjustment component 32, enables drying treatment at different locations.
