Description

Technical Field

[0001] The present disclosure relates to the technical field of internal mixers, and in particular to a dust suction hood, a dust-proof component, a dust-proof mechanism, and a processing device. Background Art

[0002] An internal mixer is an indispensable device in the mixing process of the rubber and plastic industries, used for uniformly mixing various raw materials. During the mixing process, the dust-proof cover plays a crucial role. It can not only prevent dust from leaking out, keep the workshop clean, but also protect operators from dust hazards. However, during the mixing process, due to the extremely high internal pressure, fine particles such as powder and carbon black in the rubber compound formula are likely to fly out from the gap between the dust-proof cover and the mixing tank, spreading in the internal space of the stand, resulting in serious air pollution. The leakage of dust not only affects the cleanliness of the workshop, but may also cause damage to the environment, especially posing a threat to the health of operators. Long-term exposure to a dust environment may lead to respiratory diseases. Although sealing strips are installed at the edges of the dust-proof cover, under high pressure, these sealing measures often cannot completely prevent the overflow of dust. Especially after the sealing strips are worn or aged, their effectiveness is further reduced. Summary of the Invention

[0036] In the related art, only one layer of dust cover is provided in the internal mixer. However, during the mixing process, due to the extremely high internal pressure, fine particles such as powder and carbon black in the rubber compound formulation are easily ejected from the gap between the dust cover and the mixing tank and scattered in the internal space of the stand, resulting in serious air pollution.

[0037] In the present disclosure, by adding a set of outer dust suction covers on the basis of the original dust-proof cover, a second dust collection barrier is formed, which not only enhances the dust interception ability but also effectively collects fine dust particles that might otherwise escape into the workshop environment.

[0038] The first aspect of the present disclosure provides a dust suction cover 100, wherein Figure 1 in an example, both ends are open in its extending direction a (in the example, it is the up-down direction of the dust suction cover), and it bends towards a side deviating from the extending direction a to form a first opening 103, so as to enclose a first space 104; at least one dust suction port 101 is penetratingly provided on the cover wall of the dust suction cover 100. Figure 1 Specifically, in an embodiment, the dust suction cover forms upper and lower openings along the extending direction a, and an opening is also provided on one side perpendicular to the upper and lower surfaces to form the first opening 103. Since the dust suction cover 100 wraps the outside of the dust-proof cover 201, the extending range of the dust suction cover 100 can be set according to the actual situation of the dust-proof cover 201, so that it can more effectively surround the dust source, and efficient dust suction can be achieved regardless of the position or shape of the dust source. Through the structure formed by bending, the dust suction cover 100 encloses a first space 104, which helps to capture and concentrate dust and prevent dust from escaping everywhere. At least one dust suction port 101 is penetratingly provided on the cover wall of the dust suction cover 100, and the dust suction port 101 can be connected to an external dust suction device through a connecting pipe 1011 for sucking the dust in the first space 104;

[0039] Specifically, Figure 1 in an embodiment, a dust suction port 101 can be respectively provided on each surface of the dust suction cover 100, or multiple dust suction ports 101 can be provided on each surface according to actual usage requirements. The number and position of the dust suction ports 101 can be adjusted according to actual needs to adapt to different working environments. Figure 1 In some embodiments, in an example, the dust suction cover 100 forms first folded edges 102 extending towards the first space 104 along the edges at both ends (in the example, it is the two open ends of the dust suction cover along the extending direction a).

[0040] In some embodiments, Figure 1 in an example, Figure 1 in an example, the dust suction cover 100 forms first folded edges 102 extending towards the first space 104 along the edges at both ends (in the example, it is the two open ends of the dust suction cover along the extending direction a).

[0041] Specifically, Figure 1In the example, the edges at the upper and lower ends of the dust suction hood 100 are bent towards the first space 104 to form a first folded edge 102; the first folded edge 102 enables the dust suction hood 100 to fit more closely to the device surface, forming a physical barrier, effectively reducing the possibility of dust escaping from the edges, and significantly improving the sealing performance of the dust suction hood 100. The first folded edge 102 also simplifies the installation and disassembly process of the dust suction hood 100, facilitating connection to the device or bracket, and can also be quickly disassembled when cleaning or maintenance is required, improving the maintenance efficiency. In Figure 1 In the example, the edges of each surface of the dust suction hood 100 are bent towards the first space 104 to form folded edges, making the edges of the dust suction hood 100 fit more closely to the device surface, as Figure 2 shown in the example, a dust suction channel 210 is formed between the folded edges of the dust suction hood 100 and the folded edges of the dust-proof cover 201.

[0042] In some embodiments, in Figure 1 the example, the extended lengths of two folded edges in the first folded edge 102 are different.

[0043] Specifically, in some embodiments, one of the longer folded edges 1021 can better cover or embed the device edge, while the shorter folded edge 1022 provides sufficient space for dust to be sucked into the first space 104 and then sucked out through the dust suction port 101.

[0044] As Figure 2 shown, in another embodiment of the present disclosure, a dust-proof component 200 can also be provided, which includes:

[0045] A dust-proof cover 201, which is open at both ends in its extending direction a, and is bent towards one side intersecting the extending direction a and has a second opening 230 to enclose a second space 220; a first seal 203 is provided at one end of the dust-proof cover 201;

[0046] The dust suction hood 100 described in any of the above embodiments is enclosed outside the wall surface of the dust-proof cover 201 facing away from the second space 220 to accommodate the dust-proof cover 201 in the first space 104, and the first opening 103 and the second opening 230 are located on the same side;

[0047] wherein, a dust suction channel 210 connecting the first seal 203 and the dust suction port 101 is formed by the gap between the wall surfaces of the dust-proof cover 201 and the dust suction hood 100.

[0048] Specifically, in Figure 2In the example, the dust-proof cover 201 is provided with three sides, and the dust suction cover 100 correspondingly has three sides as well, and they have the same opening surface as the dust-proof cover 201, so that the dust suction cover 100 can cover the outer wall of the dust-proof cover 201, and a dust suction channel 210 is formed between the dust-proof cover 201 and the dust suction cover 100, ensuring that the dust suction cover 100 can effectively capture the dust escaping from the dust-proof cover 201.

[0049] The shapes of the dust suction cover 100 and the dust-proof cover 201 can be changed according to the actual situation. The dust-proof cover 201 needs to fit the dust suction cover 100 so that the dust-proof cover 201 can surround the dust suction cover 100 in the extending direction a, form a dust suction channel 210 for dust suction between the dust-proof cover 201 and the dust suction cover 100, and form an opening on the same side.

[0050] In some embodiments, the dust-proof cover 201 is arranged above the dust source to cover the dust source. However, due to the problem of the pressure difference inside and outside the dust-proof cover 201, some dust may overflow from the dust-proof cover 201. Therefore, a dust suction cover 100 is also arranged outside the dust-proof cover 201. The dust suction cover 100 includes the dust-proof cover 201 and the dust source, so that the dust between the dust-proof cover 201 and the dust suction cover 100 can be prevented by the dust suction cover and sucked out through the dust suction port 101; through the double structure of the dust-proof cover 201 and the dust suction cover 100, combined with the design of the first seal 203 and the dust suction channel 210, it is ensured that the dust can be quickly captured after escaping from the dust source, reducing the diffusion of dust in the workshop and significantly improving the dust control effect. Among them, the first seal 203 enhances the sealing performance between the dust-proof cover 201 and the dust source.

[0051] In some embodiments, as Figure 2 shown in the example, the dust suction cover 100 forms a first folded edge 102 extending towards the first space 104 at both ends along the edge, and the dust-proof cover 201 forms a second folded edge 202 extending away from the second space 220 at both ends along the edge to enclose a dust suction channel 210 located between the first folded edge 102 and the second folded edge 202; the first seal 203 is wrapped around one of the folded edges of the second folded edge 202. In Figure 2 the example, the first seal 203 is wrapped around 2022.

[0052] Specifically, in some embodiments, the upper and lower edges of the dust cover 201 extend and bend to form a second folded edge 202. The first folded edge 102 and the second folded edge 202 cooperate, and the two folded edges extend towards each other to enclose a dust suction channel 210, ensuring that the dust escaping from the dust cover 201 can be effectively guided and captured, avoiding the dispersion of dust. The first seal 203 is wrapped around one of the folded edges (203) of the second folded edge 202, enhancing the sealing between the dust cover 201 and the dust source, reducing the chance of dust leakage from the edge. At the same time, the combination of the first seal 203 and the second folded edge 202 ensures the integrity and effectiveness of the dust suction channel.

[0053] In some embodiments, as Figure 2 shown in the example, the two folded edges of the first folded edge 102 and the second folded edge 202 that are away from the first seal 203, Figure 1 in the example are at least partially overlapped and lapped between the folded edge 1021 in the dust suction cover 100 and the folded edge 2021 in the dust cover 201.

[0054] Specifically, the two folded edges of the first folded edge 102 and the second folded edge 202 that are away from the first seal 203, the folded edge 1021 in the dust suction cover 100 and the folded edge 2021 in the dust cover 202 are at least partially overlapped and lapped, so as to effectively prevent dust from escaping from the gap between the folded edges, strengthening the overall sealing of the dust prevention assembly 200.

[0055] In some embodiments, a second seal 2023 is provided between the two lapped folded edges.

[0056] Specifically, in Figure 2 the example, the second seal 2023 is also wrapped around the folded edge 2021 of the dust cover 201, effectively filling the possible tiny gaps at the lap of the folded edges, significantly enhancing the sealing of the dust prevention assembly 200, preventing dust from escaping from the lap of the folded edges, and ensuring the efficiency and reliability of dust capture.

[0057] In some embodiments, the folded edge of the first folded edge 102 that is disposed close to the same end as the first seal 203 is farther from the other end than the first seal 203 in the extension direction a.

[0058] Specifically, in Figure 2 the example, the folded edge 1022 of the first folded edge 102 that is close to the first seal 203 forms a gap with the first seal 203 for forming a dust suction channel, so that dust is inhaled into the dust suction channel 210 through the gap.

[0059] In yet another embodiment of the present disclosure, a dust prevention mechanism can also be provided, wherein, in Figure 3In the example, it includes:

[0060] A driving assembly 300, including: a telescopic assembly 301 that can telescopically extend along a movement direction b;

[0061] The dust-proof assembly 200 described in any of the above embodiments is fixedly connected to the telescopic assembly 301 in a manner that the extending direction a is consistent with the movement direction b, so as to be driven.

[0062] Specifically, in Figure 3 the example, the telescopic assembly 301 includes fixing rods 3011 respectively fixed at the four vertices of the upper end opening of the dust-proof assembly. The other ends of the two fixing rods 3011 connected to the upper end of the first opening are fixed by a cross bar 3012, and the same is true for the other two fixing rods 3011; the connecting rod 3012 is connected to the driving member in the driving assembly 300. In Figure 3 the example, it is a cylinder 303. By connecting the piston rod 3031 of the cylinder 303, the fixing rods 3011 move up and down along the movement direction b with the piston rod 3031, thereby driving the dust-proof assembly 200 to move; in order to drive the fixing rods 3011 simultaneously, the two cylinders 303 are connected by a connecting rod 3032 to ensure driving consistency.

[0063] On both sides of the first opening 103 of the dust-proof cover 201, there is also a pair of guide rods 302 arranged along the movement direction b, so that the dust-proof assembly 200 can move along the guide rods 302.

[0064] In another embodiment of the present disclosure, a processing device can also be provided. Among them, in Figure 4 the example, it includes:

[0065] A workbench 400, provided with a feeding groove with an upward notch;

[0066] A frame body 500, provided with a fixed cover 501 located above the notch of the feeding groove;

[0067] The dust-proof mechanism described in the above embodiments is arranged above the workbench 400 and is configured such that the dust-proof assembly 200 is sleeved on the fixed cover 501 and can move up and down, and can move to cover the gap between the fixed cover 501 and the notch to form an internal closed space with the fixed cover 501; in Figure 4 the example, the state where the notch of the feeding groove is sealed by the dust-proof assembly 200 is shown. When the dust-proof assembly moves upward along the movement direction b, the notch will be exposed for feeding.

[0068] Among them, the dust suction port 101 on the dust suction hood 100 is for connection to a dust suction device 1011.

[0069] Specifically, in some embodiments, the processing equipment is equipped with a workbench 400, on which a feeding groove with an upward notch is provided for importing materials; a fixed cover 501 is provided on the frame body 500, and the fixed cover 501 is located above the notch of the feeding groove for preliminary dust shielding; a dust-proof mechanism is arranged above the workbench 400, wherein the dust-proof component 200 is sleeved on the fixed cover 501 and can move in the up and down direction. When the dust-proof component 200 moves downward, it can cover the gap between the fixed cover 501 and the notch, and form an internal closed space with the fixed cover 501, thereby effectively isolating the external environment and preventing dust from leaking. The dust suction port 101 on the dust suction hood 100 is connected to the dust suction device 1011. Through the operation of the dust suction device 1011, the dust in the closed space is efficiently captured and removed to ensure the cleanliness of the working environment.

[0070] The above embodiments are only illustrative of the principles and effects of the present disclosure, and are not used to limit the present disclosure. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present disclosure should still be covered by the protection scope of the present disclosure.
