Description

Technical Field

[0001] This utility model relates to the field of sound insulation material production technology, specifically to a drying oven for producing sound insulation materials. Background Technology

[0002] Sound insulation materials refer to a class of materials, components or structures that can reduce or block the propagation of sound or weaken transmitted sound energy. With the continuous updates and development of the automotive industry, the demand for sound insulation in automobiles is also constantly increasing, and PET sound-absorbing and insulating materials play an important role in automotive noise reduction processes.

[0003] In the production and processing of PET sound-absorbing and insulating materials, it is necessary to strictly control various processing techniques to ensure the quality of PET sound-absorbing and insulating materials. Among them, the drying oven for PET sound-absorbing and insulating materials is a device used to dry PET sound-absorbing and insulating materials during the production and processing of PET sound-absorbing and insulating materials.

[0004] For example, a hot air circulating oven for the production of sound insulation materials, with application number CN202020930600.9, includes an oven, partition, drying chamber, upper air chamber, ventilation holes, air supply pipe, air spray pipe, hose, heating wire box, and blower fan. The air supply pipe can be driven to swing through a drive device. When the air supply pipe swings, the area of ​​the hot air sprayed can be increased to ensure uniform air spray and thus ensure uniform drying of the material.

[0005] In the aforementioned patent, sound insulation material is placed on a frustum-shaped material plate. A blower fan blows cold air from the outside through an air inlet pipe into the heating wire box, where it is heated. The heated air becomes hot air, enters the inside of a flexible hose, then the air supply pipe, and finally sprays out from the air spray pipe to dry the sound insulation material. Since the sound insulation material is placed directly on the frustum-shaped material plate, it needs to be turned over to fully dry it. However, due to the high temperature inside the oven, directly turning the material inside the oven is not only space-constrained but also prone to causing burns.

[0006] Therefore, we have proposed an oven for the production of sound insulation materials to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide an oven for the production of sound insulation materials, so as to solve the problem mentioned in the background art that, due to the high temperature inside the oven, direct operation and turning inside the oven is not only limited by space, but also prone to burns.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an oven for producing sound insulation materials, comprising an oven body and ventilation holes on both sides of the lower end of the inner wall of the oven body; return air pipes are respectively connected to the upper ends of the cavities on both sides of the outer wall of the oven body; one end of the return air pipe is connected to a drying chamber; a drive assembly is provided at the upper end of the inner cavity of the oven body; a heating wire box is connected to one end of the drying chamber through a pipe; a blower assembly is connected to one end of the heating wire box through an air inlet pipe; and a placement assembly is movably installed in the inner cavity of the oven body, the placement assembly being configured to accommodate the sound insulation materials.

[0009] The placement assembly includes a fixing mechanism and a clamping mechanism threadedly connected to the upper middle part of the fixing mechanism. Supporting mechanisms are movably installed on both sides of the outer wall of the fixing mechanism. A limiting mechanism is threadedly connected to the upper end of the supporting mechanism. The fixing mechanism and the clamping mechanism are configured to limit the placement of the sound insulation material. The supporting mechanism is configured to drive the fixing mechanism and the clamping mechanism to move in position. The limiting mechanism is configured to fix the active rotation angle of the fixing mechanism and the clamping mechanism.

[0010] Preferably, the oven body includes a bottom plate and T-shaped sliding grooves respectively formed on both sides of the upper end of the bottom plate.

[0011] Preferably, the fixing mechanism includes a placement block and a threaded block fixedly installed in the middle of the inner cavity of the placement block via a connecting rod. Extension rods are fixedly installed on both sides of the outer wall of the placement block, and an H-shaped limiting rod is fixedly installed at one end of the extension rod.

[0012] Preferably, the pressing mechanism includes a sealing cover and a T-shaped threaded rod fixedly installed in the middle of the inner cavity of the sealing cover via a connecting rod. A rotating ring is fixedly installed at the upper end of the sealing cover, and an intercepting net is embedded in the upper end of the inner cavity of the sealing cover.

[0013] Preferably, the support mechanism includes a T-shaped sliding block and a locking block fixedly installed at both ends of the upper side of the T-shaped sliding block. A vertical block is fixedly installed at the middle of the upper end of the T-shaped sliding block. Multiple air passage slots are linearly and equally spaced on one side of the outer wall of the vertical block. A circular groove is opened at the middle of the upper side of the vertical block. A threaded groove is opened at the middle of the upper end of the inner wall of the circular groove.

[0014] Preferably, the limiting mechanism includes a threaded rod and a semi-circular block mounted on the lower end of the threaded rod via a bearing.

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

[0016] 1. By setting up a circular block, a T-shaped threaded rod, a threaded circular block, a sealing cover, a blocking net, a blower fan, a heating wire box, a blower assembly, an extension rod, an H-shaped limiting rod, a vertical block, and a T-shaped sliding block, after the sound insulation material at the top of the circular block is dried, the circular block drives the extension rod, the H-shaped limiting rod, the vertical block, and the T-shaped sliding block to be pulled out from the inner cavity of the drying chamber. This allows the T-shaped sliding block to slide out from the inner cavity of the T-shaped sliding groove. After the H-shaped limiting rod is loosened by the limiting mechanism, the circular block is flipped to flip the sound insulation material. The limiting mechanism then fixes the flipped circular block in place. This eliminates the need for the operator to manually flip the dried sound insulation material. Furthermore, removing the circular block from the inner cavity of the drying chamber facilitates the handling and placement of the sound insulation material, making it convenient to use.

[0017] 2. The operator rotates the threaded rod to move the semicircular block upward from the inner cavity of the circular groove, thereby loosening the semicircular block's pressure on the upper end of the H-shaped limit rod. Conversely, the operator rotates the threaded rod again to move the semicircular block to press the H-shaped limit rod into the inner cavity of the circular groove, thus fixing the position of the flipped circular block in the inner cavity.

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.

[0024] Example 1: Please refer to Figures 1-3 An oven for producing sound insulation materials includes an oven body 1 and ventilation holes 2 on both sides of the lower end of the inner wall of the oven body 1. The upper ends of the cavities on both sides of the outer wall of the oven body 1 are respectively connected to return air pipes 3. One end of the return air pipes 3 is connected to a drying chamber 5. A drive assembly 4 is provided at the upper end of the inner cavity of the oven body 1. One end of the drying chamber 5 is connected to a heating wire box 6 through a pipe. One end of the heating wire box 6 is connected to a blower assembly 7. A blower fan 8 is connected to one side of the outer wall of the heating wire box 6 through an air inlet pipe. A placement assembly 9 is movably installed in the inner cavity of the oven body 1. The placement assembly 9 is set to accommodate the sound insulation materials.

[0025] The structure and working principle of the oven body 1, ventilation hole 2, return air pipe 3, drive assembly 4, drying box 5, heating wire box 6, air spray assembly 7, and blower fan 8 are the same as those of the ventilation hole, oven, partition, upper air chamber, drying chamber, return air pipe, drive device, hydraulic cylinder, limit plate, stabilizing gear, drive gear, toothed column, drying box, heating wire box, hose, bracket, frustum-shaped material plate, cylinder, hollow ring, mesh plate, partition, receiving cavity, blower fan, air inlet pipe, power rod, air supply pipe, connecting rod, and air spray pipe in CN212481907U. Therefore, they will not be described in detail here.

[0026] The drying oven, heating wire box, and blower are all existing technologies and are not limited here. They can be purchased as finished products from the market and installed.

[0027] The placement component 9 includes a fixing mechanism 91 and a clamping mechanism 92 threadedly connected to the upper middle part of the fixing mechanism 91. Supporting mechanisms 93 are movably installed on both sides of the outer wall of the fixing mechanism 91. A limiting mechanism 94 is threadedly connected to the upper end of the supporting mechanism 93. The fixing mechanism 91 and the clamping mechanism 92 are configured to limit the placement of the sound insulation material. The supporting mechanism 93 is configured to drive the fixing mechanism 91 and the clamping mechanism 92 to move in position. The limiting mechanism 94 is configured to fix the active rotation angle of the fixing mechanism 91 and the clamping mechanism 92.

[0028] The oven body 1 includes a bottom plate 11 and T-shaped sliding grooves 12 respectively opened on both sides of the upper end of the bottom plate 11. A slot (not shown in the figure) is opened in the middle of the upper end of the inner wall of the T-shaped sliding groove 12. The T-shaped sliding block 931 is movably installed in the inner cavity of the T-shaped sliding groove 12, and the slot is movably installed in the inner cavity of the slot. The slot is set to limit the T-shaped sliding block 931.

[0029] The fixing mechanism 91 includes a mounting block 911 and a threaded block 912 fixedly installed in the middle of the inner cavity of the mounting block 911 by a connecting rod. The mounting block 911 is configured to accommodate sound insulation material.

[0030] An extension rod 913 is fixedly installed on both sides of the outer wall of the placement block 911. An H-shaped limiting rod 914 is fixedly installed at one end of the extension rod 913. The H-shaped limiting rod 914 is movably installed in the inner cavity of the circular groove 935. By rotating the H-shaped limiting rod 914, it is suitable to drive the placement block 911 to perform a flipping motion.

[0031] The clamping mechanism 92 includes a sealing cover 921 and a T-shaped threaded rod 922 fixedly installed in the middle of the inner cavity of the sealing cover 921 via a connecting rod. The sealing cover 921 is threadedly connected to the inner cavity of the threaded block 912 via the T-shaped threaded rod 922, so as to limit the sealing cover 921 to the upper end of the placement block 911, thereby limiting the sound insulation material placed in the inner cavity of the placement block 911 through the sealing cover 921.

[0032] A rotating ring 924 is fixedly installed on the upper end of the sealing cover 921, and an intercepting net 923 is embedded in the upper end of the inner cavity of the sealing cover 921. At the same time, the intercepting net 923 allows hot air to pass through and dry the sound insulation material.

[0033] The support mechanism 93 includes a T-shaped sliding block 931 and a locking block 932 fixedly installed at both ends of the upper side of the T-shaped sliding block 931. A vertical block 933 is fixedly installed in the middle of the upper end of the T-shaped sliding block 931. A plurality of air passage slots 934 are linearly and equally spaced on one side of the outer wall of the vertical block 933. The air passage slots 934 are provided to allow hot air to pass through.

[0034] In this embodiment: by placing the sound insulation material on the upper end of the placement block 911, and by threading the T-shaped threaded rod 922 into the inner cavity of the threaded block 912, the sealing cover 921 and the intercepting net 923 are pressed and limited on the sound insulation material on the upper end of the placement block 911, thereby limiting the placement of the sound insulation material. When the blower fan 8 is started, the outside cold air is blown into the interior of the heating wire box 6 through the air inlet pipe and heated. The heated air becomes hot air and enters the interior of the air spray assembly 7. It is then sprayed out through the air spray pipe of the air spray assembly 7 to dry the sound insulation material.

[0035] Furthermore, after the sound insulation material on the upper part of the placement block 911 is dried, the operator can open the door of the drying chamber and pull the placement block 911, along with the extension rod 913, H-shaped limiting rod 914, vertical block 933, and T-shaped sliding block 931, out of the inner cavity of the drying chamber. This allows the T-shaped sliding block 931 to slide out of the inner cavity of the T-shaped sliding groove 12. After the operator loosens the H-shaped limiting rod 914 through the limiting mechanism 94, the placement block 911 is flipped to flip the sound insulation material. The position of the flipped placement block 911 is then fixed by the limiting mechanism 94. There is no need for the operator to manually flip the dried sound insulation material. Moreover, by removing the placement block 911 from the inner cavity of the drying chamber, it is also convenient to take out and place the sound insulation material, making it easy to use.

[0036] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 A circular groove 935 is provided in the middle of one side of the upper end of the vertical block 933, and a threaded groove 936 is provided in the middle of the upper end of the inner wall of the circular groove 935.

[0037] The limiting mechanism 94 includes a threaded rod 941 and a semicircular block 942 mounted on the lower end of the threaded rod 941 via a bearing. The semicircular block 942 is movably mounted in the inner cavity of the circular groove 935 and is threadedly connected to the threaded groove 936 via the threaded rod 941, thereby driving the semicircular block 942 to move up and down within the inner cavity of the circular groove 935.

[0038] In this embodiment: the operator rotates the threaded rod 941 to drive the semi-circular block 942 to rise and move from the inner cavity of the circular groove 935, thereby loosening the clamping of the semi-circular block 942 on the upper end of the H-shaped limiting rod 914. At this time, the operator can flip the placement block 911 directly to flip the sound insulation material. Then, the operator rotates the threaded rod 941 again to drive the semi-circular block 942 to press the H-shaped limiting rod 914 into the inner cavity of the circular groove 935 and fix it. This fixes the position of the flipped placement block 911 in the inner cavity. The placement block 911 is then pushed back into the drying oven for drying.

[0039] Working principle: By placing the sound insulation material on the upper end of the mounting block 911, and then threading the T-shaped threaded rod 922 into the inner cavity of the threaded block 912, the sealing cover 921 and the intercepting net 923 are pressed and limited onto the sound insulation material on the upper end of the mounting block 911. The blower fan 8 is activated to blow cold air from the outside into the heating wire box 6 through the air inlet pipe. The heated air becomes hot air and enters the air spray assembly 7. It is then sprayed out through the air spray pipe of the air spray assembly 7 to dry the sound insulation material. After the sound insulation material on the upper end of the mounting block 911 is dried, the operator can open the door of the drying box and move the mounting block 911 to drive the extension rod 913, the H-shaped limiting rod 914, the vertical block 933, and the T-shaped threaded rod 922 into the inner cavity of the threaded block 912. The T-shaped sliding block 931 is pulled out from the inner cavity of the drying chamber, causing it to slide out from the inner cavity of the T-shaped sliding groove 12. The operator rotates the threaded rod 941 to drive the semi-circular block 942 to rise and move from the inner cavity of the circular groove 935, thereby loosening the pressure of the semi-circular block 942 on the upper end of the H-shaped limiting rod 914. At this time, the operator can flip the placement circular block 911 directly to flip the sound insulation material. Then, the threaded rod 941 is rotated again to drive the semi-circular block 942 to press the H-shaped limiting rod 914 into the inner cavity of the circular groove 935 and fix it. This fixes the position of the flipped placement circular block 911 in the inner cavity. The placement circular block 911 is then pushed back into the drying chamber for drying.
