Description

Technical Field

[0001] This utility model relates to the technical field of vacuum sealing machines, specifically to a shock absorption mechanism for a vacuum sealing machine and the vacuum sealing machine thereof. Background Technology

[0002] Vacuum sealing machines, as highly efficient food preservation and item storage equipment, primarily function to remove air from packaging bags before heat-sealing the bag opening, creating a vacuum environment that effectively delays oxidation and spoilage. In existing technologies, vacuum sealing machines typically integrate a vacuum extraction module to achieve this function. For example, a bag-sealing machine disclosed in Chinese Patent Publication No. CN115593692A forms a sealed chamber by closing upper and lower compartments and utilizes a built-in air pump for air extraction.

[0003] However, in the actual operation of the above and similar structures, a common technical defect has become increasingly apparent: the air pump (or vacuum pump) as the power source inevitably generates continuous mechanical vibration when operating at high speed. This vibration produces noise. Therefore, to address the noise problems caused by air pump vibration in existing vacuum sealing machines, an effective vibration reduction and noise reduction structure is designed. Utility Model Content

[0004] This utility model proposes a vibration damping mechanism for a vacuum sealing machine and the vacuum sealing machine itself. The vibration damping and noise reduction component encloses the outer periphery of the air pump through a covering part. The mechanical vibration generated by the air pump during operation is absorbed by the covering part, reducing noise caused by vibration at the source. The enclosed design of the outer periphery of the air pump does not affect the heat dissipation of the air pump, and also buffers the vibration of the air pump during operation. This ensures the air pump is installed stably, reduces noise, and is compatible with the installation space of existing vacuum sealing machines.

[0005] A vibration damping mechanism for a vacuum sealing machine designed for this purpose includes a vibration damping and noise reduction component fixed to the machine body and assembled with an air pump. The vibration damping and noise reduction component is provided with a covering part for clamping the outer periphery of the air pump, so as to absorb the vibration generated by the air pump during the vacuum operation of the vacuum sealing machine, thereby achieving vibration damping and noise reduction.

[0006] The upper part of the shock-absorbing and noise-reducing component is open for disassembling or installing the air pump, and the lower part of the shock-absorbing and noise-reducing component is used to support the air pump.

[0007] The covering part is annular and is located on the upper part of the air pump. The covering part has a vertically penetrating mounting cavity, and the air pump is vertically mounted on the mounting cavity.

[0008] The lower part of the shock-absorbing and noise-reducing component is provided with a support block, and the covering part is provided with a connecting block that extends downward and is connected to the support block. When the air pump is assembled with the shock-absorbing and noise-reducing component, the bottom of the air pump is supported on the support block.

[0009] The support block is provided with fixing holes for inserting fasteners, and the bottom of the air pump is fixedly engaged with the support block by fasteners.

[0010] The end of the covering part is provided with a connecting ear for fixedly engaging with the body. The connecting ear is provided with an assembly hole for inserting fasteners. The shock-absorbing and noise-reducing component is fixed to the body by fasteners.

[0011] The connecting ear extends laterally along the outer side of the covering portion.

[0012] The vibration damping and noise reduction component is made of a soft material. The vibration damping mechanism also includes a fixing component that cooperates with the vibration damping and noise reduction component to fix the air pump. The fixing component is made of a rigid or soft material, and has a through mounting groove on it. The fixing component also has a mounting hole, into which the air pump is inserted and fixedly engaged with the mounting hole.

[0013] A vacuum sealing machine having the above-mentioned shock absorption mechanism includes a machine body, the vacuum sealing machine comprising: The chamber assembly is mounted on the machine body and has an open and closed state. When the chamber assembly is open, it allows the part to be sealed to enter. When the chamber assembly is closed, it forms a closed cavity so that the sealing machine can vacuum seal the part to be sealed. An air pump is fixed inside the machine body by shock-absorbing and noise-reducing components. The air pump input end is connected to the chamber assembly. The gas in the part to be sealed is output through the sealing chamber and the air pump.

[0014] The machine body has a mounting plate with a fixing component. The fixing component has a through-groove mounting groove and a mounting hole. The shock-absorbing and noise-reducing component has a connecting ear extending outward along the covering part. The shock-absorbing and noise-reducing component is inserted into the mounting groove, and the connecting ear is supported on the fixing component. The connecting ear and the mounting hole are fixedly engaged by fasteners.

[0015] The shock-absorbing and noise-reducing components are suspended and fixed inside the machine body by fasteners, so that the bottom of the air pump is suspended and fixed inside the machine body.

[0016] The beneficial technical effects of this utility model are as follows: The vibration damping and noise reduction components enclose the outer periphery of the air pump through a covering part. The mechanical vibration generated by the air pump during operation is absorbed by the covering part, reducing noise caused by vibration at the source. The enclosed design of the outer periphery of the air pump does not affect the heat dissipation of the air pump, and also buffers the vibration of the air pump during operation. This ensures that the air pump is installed stably, reduces noise, and is compatible with the installation space of existing vacuum sealing machines. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0022] See Figures 1-4 A vibration damping mechanism for a vacuum sealing machine includes a vibration damping and noise reduction component 3 fixed to the machine body 1 and assembled with an air pump 2. The vibration damping and noise reduction component 3 is provided with a covering part 301 for clamping the outer periphery of the air pump 2, so as to absorb the vibration generated by the air pump 2 during the vacuum operation of the vacuum sealing machine, thereby achieving vibration damping and noise reduction.

[0023] The vibration damping and noise reduction component 3 encloses the outer periphery of the air pump 2 through the covering part 301. The mechanical vibration generated by the operation of the air pump 2 is absorbed by the covering part 301, reducing the noise caused by vibration at the source. The enclosed design of the outer periphery of the air pump 2 does not affect the heat dissipation of the air pump 2, and also buffers the vibration of the air pump 2 during operation. This ensures that the air pump 2 is installed stably, reduces noise, and is compatible with the installation space of existing vacuum sealing machines.

[0024] The upper part of the shock-absorbing and noise-reducing component 3 is open to allow for the disassembly or installation of the air pump 2, while the lower part of the shock-absorbing and noise-reducing component 3 is used to support the air pump 2.

[0025] The open design of the upper part of the shock-absorbing and noise-reducing component 3 allows the air pump 2 to be installed and removed directly on the shock-absorbing and noise-reducing component 3 without disassembling it, which greatly improves the convenience of air pump 2 assembly and maintenance; the lower structure that supports the air pump 2 provides support for the bottom of the air pump 2 and absorbs the vibration of the bottom of the air pump 2.

[0026] The covering part 301 is annular and is located on the upper part of the air pump 2. The covering part 301 has a vertically penetrating mounting cavity 302, and the air pump 2 is vertically mounted on the mounting cavity 302.

[0027] The annular covering part 301 can circumferentially limit the air pump 2 and prevent the air pump 2 from swaying too much.

[0028] The vibration damping and noise reduction component 3 has a support block 303 at its lower part, and the covering part 301 has a connecting block 304 that extends downward and is connected to the support block 303. When the air pump 2 is assembled with the vibration damping and noise reduction component 3, the bottom of the air pump 2 is supported on the support block 303. The connecting block 304 connects the covering part 301 and the support block 303 into a whole, so that the vibration damping and noise reduction component 3 forms a support and fixing structure of "the upper part of the air pump 2 is covered and the bottom of the air pump 2 is supported".

[0029] The support block 303 is provided with fixing holes 305 for inserting fasteners. The bottom of the air pump 2 is fixedly engaged with the support block 303 by fasteners. The fasteners are screws. The fixing holes 305 on the support block 303 securely fix the bottom of the air pump 2 to the support block 303 by fasteners, preventing relative displacement between the air pump 2 and the support block 303 due to vibration during operation.

[0030] The end of the covering part 301 is provided with a connecting ear 306 for fixedly engaging with the body 1. The connecting ear 306 is provided with a mounting hole 307 for inserting a fastener. The vibration damping and noise reduction component 3 is fixed to the body 1 by fasteners. The fasteners are screws. The connecting ear 306 provides a reliable fixing point for the vibration damping and noise reduction component 3 to the body 1. The mounting hole 307 achieves a firm connection between the vibration damping and noise reduction component 3 and the body 1 through the fasteners, preventing the vibration damping and noise reduction component 3 from shifting during the operation of the air pump 2 and ensuring the stability of the air pump 2's installation position.

[0031] The connecting ear 306 extends laterally along the outer side of the covering portion 301. The connecting ear 306 extends laterally along the outer side of the covering portion 301, increasing the contact force-bearing area.

[0032] The vibration damping and noise reduction component 3 is made of soft material. The vibration damping and noise reduction component 3 is made of soft material, which has good elasticity and cushioning performance, and can directly absorb the mechanical vibration generated by the air pump 2. The soft material is silicone.

[0033] The shock absorption mechanism also includes a fixing part 5 that cooperates with the shock absorption and noise reduction component 3 to fix the air pump 2. The fixing part 5 is made of a rigid material (plastic with high hardness) or a soft material (silicone with higher hardness than the shock absorption and noise reduction component 3). The fixing part 5 is provided with an assembly groove 501 that runs vertically through the top and bottom. The fixing part 5 is also provided with a mounting hole 502. The air pump 2 is inserted into the assembly groove 501 and fixedly cooperates with the mounting hole 502.

[0034] A vacuum sealing machine having the above-mentioned shock absorption mechanism includes a machine body 1, wherein the vacuum sealing machine includes: The chamber assembly is mounted on the machine body 1 and has an open and closed state. When the chamber assembly is open, it allows the part to be sealed to enter. When the chamber assembly is closed, it forms a closed cavity so that the sealing machine can vacuum seal the part to be sealed. Air pump 2 is fixed inside the body 1 by shock-absorbing and noise-reducing component 3. The input end of air pump 2 is connected to the chamber assembly. The gas in the part to be sealed is output through the closing chamber and air pump 2.

[0035] The body 1 contains a mounting plate 4, on which a fixing member 5 is provided. The fixing member 5 has a vertically penetrating mounting groove 501 and a mounting hole 502. The shock-absorbing and noise-reducing component 3 has a connecting ear 306 extending outward from the covering part 301. The shock-absorbing and noise-reducing component 3 is inserted into the mounting groove 501, and the connecting ear 306 is supported on the fixing member 5. The connecting ear 306 and the mounting hole 502 are fixedly engaged by fasteners. The mounting hole 502 is aligned with the mounting hole 307 and a screw is inserted.

[0036] The fastener 5 is fixed to the mounting plate 4 by welding or screws.

[0037] The shock-absorbing and noise-reducing component 3 is suspended and fixed inside the body 1 by the fixing component 5, so that the bottom of the air pump 2 is suspended and fixed inside the body 1. The suspension and fixing of the shock-absorbing and noise-reducing component 3 prevents the bottom of the air pump 2 from directly contacting the body 1, thereby reducing the noise generated by vibration.

[0038] The specific structure of the compartment assembly can be found in Chinese Patent Publication No. CN218432081U, which discloses a rapid bag sealing machine, or Chinese Patent Publication No. CN120942677A, which discloses a vacuum sealing machine. Therefore, the specific structure of the compartment assembly will not be described in detail here. In general, the compartment assembly includes an upper compartment and a lower compartment, with rollers between the upper and lower compartments. One of the rollers is equipped with a heating element and is driven to rotate by a motor. The bag passes between the two rollers, achieving heat sealing.
