Description

Technical Field

[0001] The utility model mainly relates to the technical field of EPS foam board production, in particular to an integrated drying and conveying machine for EPS foam. Background Art

[0002] EPS foam board, also known as polystyrene foam board or EPS board, is short for expandable polystyrene. It is made from raw materials through pre-expansion, maturation, molding, drying, and cutting. It can be made into foam products of varying densities and shapes, as well as foam sheets of varying thicknesses. It is widely used in construction, insulation, packaging, refrigeration, daily necessities, industrial casting, and other fields. It can also be used in the manufacture of display cases, advertising signs, and toys.

[0003] Currently, EPS foam is used to make television display screen packaging. Because this packaging needs to be anti-static, the manufacturing process requires immersing the packaging in an antistatic fluid. The existing treatment process involves creating a large tank of antistatic fluid, manually pouring the EPS foam packaging into the tank for immersion, typically for one minute. After immersion, the EPS foam pieces must be manually scooped out one by one, draining most of the antistatic fluid before being moved to the next workstation. This presents the following technical issues:

[0004] First, the existing method is not highly automated or intelligent. After soaking, the immersion process requires manual removal and draining, followed by manual transport to the next workstation. This increases labor intensity and leads to low production efficiency.

[0005] Second, existing methods suffer from poor drainage. Because EPS foam can have multiple concave and convex surfaces, manual draining can result in either inadequate drying, impacting subsequent operations and final product delivery. Alternatively, even if drying is achieved, the drying time can be excessively long, significantly impacting production cycles. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an all-in-one drying and conveying machine for EPS foam with high automation and intelligence, which can reduce labor intensity, improve work efficiency and have good drying effect.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A drying and conveying integrated machine for EPS foam comprises a roller transmission line assembly and a shell surrounding the roller transmission line assembly, the shell being provided with an inlet and an outlet, a vertical first partition being provided in the shell for dividing the shell into a first top-blowing drying chamber and a bottom-blowing drying chamber, a strong hot air mechanism being provided above the roller transmission line assembly in the first top-blowing drying chamber for performing a first strong hot air drying from top to bottom on the EPS foam transmitted from the inlet, and a first soft hot air mechanism being provided below the conveying surface of the roller transmission line assembly in the bottom-blowing drying chamber for performing a second soft hot air drying from bottom to top on the EPS foam transmitted from the first top-blowing drying chamber.

[0009] As a further improvement of the above technical solution:

[0010] The strong hot air mechanism includes a first hot air blower assembly and multiple first air outlet horn covers. The multiple first air outlet horn covers are arranged downward in sequence along the transmission direction of the roller transmission line assembly. The first hot air blower assembly is connected to the multiple first air outlet horn covers at the same time through a pipeline.

[0011] A residual liquid collecting hopper is provided below the roller transmission line assembly in the first top-blowing drying chamber for collecting and recovering the electrostatic liquid blown down from above, and a valve extending outward from the shell is provided at the bottom of the residual liquid collecting hopper.

[0012] A layer of filter screen is laid at the top opening of the residual liquid collecting hopper for filtering the electrostatic liquid.

[0013] The first soft hot air mechanism includes a second hot air blower assembly and multiple second air outlet horn covers. The multiple second air outlet horn covers are arranged upward in sequence below the conveying surface of the roller transmission line assembly along the transmission direction of the roller transmission line assembly. The second hot air blower assembly is connected to the multiple second air outlet horn covers at the same time through a pipeline.

[0014] The bottom blowing drying chamber is provided with a plurality of movable limit assemblies above the roller transmission line assembly. The plurality of limit assemblies are arranged downward in sequence along the transmission direction of the roller transmission line assembly and are used to press against the EPS foam transmitted below so that the EPS foam will not be blown off during the secondary soft hot air drying.

[0015] The limiting assembly includes a transversely arranged roller rod, both ends of which are fixed to the housing through bearings. A plurality of protruding flexible bristle portions are provided on the circumference of the roller rod for pressing against the EPS foam transmitted below.

[0016] A vertical second partition is provided in the shell to separate a second top-blowing drying chamber on the rear side of the bottom-blowing drying chamber in the shell. A second soft hot air mechanism is provided above the roller transmission line assembly in the second top-blowing drying chamber to perform three-step soft hot air drying from top to bottom on the EPS foam transmitted from the bottom-blowing drying chamber.

[0017] The second soft hot air mechanism includes a third hot air blower assembly and multiple third air outlet horn covers. The multiple third air outlet horn covers are arranged downward in sequence above the roller transmission line assembly along the transmission direction of the roller transmission line assembly. The third hot air blower assembly is connected to the multiple third air outlet horn covers at the same time through a pipeline.

[0018] A return air duct is provided on the top of the shell, the air inlet end of the return air duct is connected to the bottom blowing drying chamber, and the air outlet end is connected to the second soft hot air mechanism. A drying box assembly is provided on the return air duct for drying the hot air from the bottom blowing drying chamber and then transporting it to the second soft hot air mechanism.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] First, this integrated drying and conveying machine for EPS foam, while providing indirect automatic conveying, features a special first top-blowing drying chamber and a bottom-blowing drying chamber, along with a strong hot air mechanism and a first soft hot air mechanism. These mechanisms enable the incoming EPS foam to be dried with both a first strong hot air and a second soft hot air drying process. This simultaneous conveying and drying process offers a high degree of automation and intelligence, significantly reducing labor intensity and improving production efficiency.

[0021] Secondly, the integrated EPS foam drying and conveying machine of this utility model provides excellent drainage. The strong hot air mechanism, which dries the EPS foam from top to bottom, not only prevents the foam from becoming tangled but also effectively removes most of the static liquid from the foam. Combined with the second, soft hot air mechanism, which dries the EPS foam from bottom to top, these two mechanisms work together to shorten the overall drying time and achieve excellent drying results.

[0022] The third embodiment of this utility model's integrated drying and conveying machine for EPS foam features a residual liquid collection hopper within the first top-blowing drying chamber, located below the roller conveyor assembly. A valve extending outward from the housing extends from the bottom of the hopper. Instead of being wasted, most of the static liquid falls into the hopper below and is then transferred through the valve for secondary use. A filter screen is installed at the top opening of the hopper to filter the static liquid.

[0023] Fourth, the integrated EPS foam drying and conveying machine of this utility model is further equipped with multiple movable limiting components within the bottom-blowing drying chamber to prevent the lightweight EPS foam from being blown off or disturbed by the secondary soft hot air below. These components can press against the EPS foam being conveyed below, effectively ensuring secondary hot air drying and conveying stability. The multiple roller rods neither hinder the conveyed EPS foam nor, through their flexible bristles, press against the EPS foam to limit its position, effectively ensuring that the conveyed EPS foam is not blown off or disturbed by the secondary soft hot air below.

[0024] Fifth, the integrated drying and conveying machine for EPS foam of this utility model further separates a second, top-blowing drying chamber from the rear of the bottom-blowing drying chamber. A second soft hot air mechanism above the roller conveyor assembly performs a third, top-down, soft hot air drying on the EPS foam. This three-stage hot air drying process, first top-down, then bottom-up, ultimately achieves excellent drying results for the EPS foam.

[0025] Sixth, the integrated drying and conveying machine for EPS foam of this utility model, by providing a return air duct, can effectively utilize the residual hot air from the bottom-blowing drying chamber, which is then channeled to the second soft hot air mechanism to form a third soft hot air drying process, greatly reducing energy consumption and being energy-saving and environmentally friendly. At the same time, to ensure the final third hot air drying, a drying box assembly is provided to dry the hot air from the bottom-blowing drying chamber, ensuring the ultimate drying effect.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0034] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0035] like Figure 1 、 Figure 2 、 Figure 3As shown, the drying and conveying integrated machine for EPS foam of this embodiment includes a roller conveyor assembly 1 and a housing 2 enclosing the roller conveyor assembly 1. The roller conveyor assembly 1 is a conventional roller conveyor, with adjacent rollers separated by gaps of a certain width. The housing 2 is provided with an inlet 21 and an outlet 22. A vertical first partition 23 is provided within the housing 2 to separate the interior of the housing 2 into a first top-blowing drying chamber 24 and a bottom-blowing drying chamber 25. In other words, the first partition 23 must have a hole through which only the roller conveyor assembly 1 and the EPS foam pass. This ensures the conveying operation of the roller conveyor assembly 1 while separating the first top-blowing drying chamber 24 and the bottom-blowing drying chamber 25 into two independent chambers. A strong hot air mechanism 3 is installed above the roller conveyor assembly 1 in the first top-blowing drying chamber 24 to perform a first strong hot air drying from top to bottom on the EPS foam delivered from the inlet 21. A first soft hot air mechanism 4 is installed below the conveying surface of the roller conveyor assembly 1 in the bottom-blowing drying chamber 25 to perform a second soft hot air drying from bottom to top on the EPS foam delivered from the first top-blowing drying chamber 24. The specific implementation principle is as follows:

[0036] This drying and conveying all-in-one machine has a long length and can be connected between the soaking tank and the next workstation for automatic transmission. For the sake of convenience, the attached drawings in the specification only show the length of one section. During operation, the multiple EPS foams after soaking are dropped one by one through the feed port 21 onto the roller transmission line assembly 1 for transmission one by one. During transmission, they will first enter the first top-blowing drying chamber 24, and then the strong hot air mechanism 3 above will start the automatic strong hot air blowing to perform the first strong hot air drying from top to bottom on the EPS foam transmitted below. Since the EPS foam is carried on the roller transmission line assembly 1, the strong hot air will not mess up the EPS foam, but will blow off most of the static liquid on the EPS foam.

[0037] The EPS foam passing through the first top-blowing drying chamber 24 will be transferred to the next bottom-blowing drying chamber 25. At this time, the first soft hot air mechanism 4 in the bottom-blowing drying chamber 25 is automatically opened. It is arranged below the conveying surface of the roller transmission line assembly 1 and can perform secondary soft hot air drying on the EPS foam from bottom to top.

[0038] Through the above special scientific design, it has the following technical advantages:

[0039] First, the integrated drying and conveying machine for EPS foam of this utility model, while providing indirect automatic conveying, is equipped with a special first top-blowing drying chamber 24 and a bottom-blowing drying chamber 25, as well as a strong hot air mechanism 3 and a first soft hot air mechanism 4. These enable the incoming EPS foam to be dried with a primary strong hot air blow and a secondary soft hot air blow. This simultaneous conveying and drying process is highly automated and intelligent, significantly reducing labor intensity and improving production efficiency.

[0040] Secondly, the integrated EPS foam drying and conveying machine of this utility model provides excellent drainage. The strong hot air mechanism 3 provides a first, top-down drying operation, preventing the EPS foam from becoming tangled while effectively removing most of the static liquid from the foam. Combined with the second, bottom-up drying operation of the first, soft hot air mechanism 4, these two combined forces result in a short overall drying time for the EPS foam, achieving excellent drying results.

[0041] In this embodiment, the strong hot air mechanism 3 includes a first hot air blower assembly 31 and multiple first air outlet horn covers 32. The multiple first air outlet horn covers 32 are arranged sequentially downward along the transmission direction of the roller transmission line assembly 1. The first hot air blower assembly 31 is connected to the multiple first air outlet horn covers 32 through a pipeline. The fan of the first hot air blower assembly 31 can blow strong air. After passing through the matching heating wire assembly, it forms a strong hot air blow, which can blow off most of the static liquid on the EPS foam and dry it.

[0042] In this embodiment, a residual liquid collection hopper 5 is provided below the roller conveyor assembly 1 within the first top-blowing drying chamber 24 to collect and recycle the static liquid blown off from above. A valve 51 extending outward from the housing 2 is provided at the bottom of the residual liquid collection hopper 5. Most of the static liquid is not wasted but instead falls into the residual liquid collection hopper 5 below and is then transferred through the valve 51 for secondary use.

[0043] In this embodiment, a filter screen 52 is provided at the top opening of the residual liquid collecting hopper 5 for filtering the electrostatic liquid.

[0044] In this embodiment, the first soft hot air mechanism 4 includes a second hot air blower assembly 41 and a plurality of second air outlet horn covers 42. The plurality of second air outlet horn covers 42 are arranged in sequence and face upward below the conveying surface of the roller transmission line assembly 1 along the transmission direction of the roller transmission line assembly 1. The second hot air blower assembly 41 is simultaneously connected to the plurality of second air outlet horn covers 42 through a pipeline. The wind force of the second hot air blower assembly 41 is not as strong as that of the first hot air blower assembly 31. The soft air blown by the second hot air blower assembly, after passing through the matching heating wire assembly, forms a relatively weak soft hot air, which can perform a secondary soft hot air drying from bottom to top on the EPS foam.

[0045] In this embodiment, multiple movable stop assemblies 6 are provided above the roller transmission line assembly 1 within the bottom-blowing drying chamber 25. These stop assemblies 6 are arranged downwardly along the transmission direction of the roller transmission line assembly 1 and are used to press against the EPS foam being conveyed below to prevent it from being blown off during the secondary soft hot air drying process. To prevent the lightweight EPS foam from being blown off or disturbed by the secondary soft hot air flow, the present invention further provides multiple movable stop assemblies 6 within the bottom-blowing drying chamber 25. These stop assemblies press against the EPS foam being conveyed below, effectively ensuring the stability of the secondary hot air drying and transmission.

[0046] In this embodiment, the limiting assembly 6 comprises a horizontally arranged roller rod, each end of which is fixed to the housing 2 via bearings. A plurality of flexible bristles are provided on the circumference of the roller rod to press against the EPS foam being transported below. The roller rods are capable of unpowered rolling, preventing any obstruction to the transported EPS foam. Furthermore, the flexible bristles press against the EPS foam to limit its position, effectively preventing the transported EPS foam from being blown off or disturbed by the secondary soft heated air flow below.

[0047] In this embodiment, a vertical second partition 26 is provided in the shell 2 to separate a second top-blowing drying chamber 27 at the rear side of the bottom-blowing drying chamber 25 in the shell 2. A second soft hot air mechanism 7 is provided in the second top-blowing drying chamber 27 above the roller transmission line assembly 1 to perform three-step soft hot air drying from top to bottom on the EPS foam transmitted from the bottom-blowing drying chamber 25. In order to further ensure the final drying effect of the EPS foam, it is prevented that the limiting assembly 6 may wet the top of the EPS foam for a second time. The utility model further separates a second top-blowing drying chamber 27 at the rear side of the bottom-blowing drying chamber 25. The EPS foam is again subjected to three-step soft hot air drying from top to bottom by the second soft hot air mechanism 7 above the roller transmission line assembly 1. This three-step hot air drying, first from top to bottom and then from top to bottom, finally achieves an excellent drying effect on the EPS foam.

[0048] In this embodiment, the second soft hot air mechanism 7 includes a third hot air blower assembly 71 and a plurality of third air outlet horn covers 72. The plurality of third air outlet horn covers 72 are arranged downwardly above the roller transmission line assembly 1 along the transmission direction of the roller transmission line assembly 1. The third hot air blower assembly 71 is connected to the plurality of third air outlet horn covers 72 via ducts. The wind from the third hot air blower assembly 71 also blows soft air. After passing through the matching heating wire assembly, it forms a relatively low-force soft hot air, which can perform three-stage soft hot air drying from top to bottom on the EPS foam.

[0049] In this embodiment, a return air duct 8 is provided on the top of the shell 2. The air inlet end of the return air duct 8 is connected to the bottom blowing drying chamber 25, and the air outlet end is connected to the second soft hot air mechanism 7. A drying box assembly 9 is provided on the return air duct 8 for drying the hot air from the bottom blowing drying chamber 25 and then conveying it to the second soft hot air mechanism 7. By providing the return air duct 8, the waste hot air from the bottom blowing drying chamber 25 can be effectively utilized, and then guided to the second soft hot air mechanism 7 to form three soft hot air dryings, which greatly reduces energy consumption and is energy-saving and environmentally friendly. At the same time, in order to ensure the final third hot air drying, by providing the drying box assembly 9, the hot air from the bottom blowing drying chamber 25 can be dried to ensure the final drying effect. Multiple layers of existing drying filters, such as cotton nets, are provided in the drying box assembly 9 to dry the air.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
