Description

Technical Field

[0001] This utility model relates to the field of yeast production equipment technology, and in particular to an installation structure for a oscillating feeder weighing module. Background Technology

[0002] Yeast production (such as pharmaceutical yeast and food-grade yeast) has extremely high requirements for material metering accuracy, environmental cleanliness, and equipment reliability. Yeast production must be carried out in a cleanroom, requiring equipment surfaces to be free of dead corners and easy to clean to avoid microbial contamination (such as the growth of miscellaneous bacteria leading to fermentation failure). Therefore, cleanrooms need to be cleaned and disinfected frequently (e.g., more than 3 times a day), resulting in equipment being in a humid environment for a long time.

[0003] Traditional weighing modules are often installed using threaded holes for fixing. The weighing module is horizontally fixed to the lower part of the vibrating feeder. On the one hand, cleaning water can easily accumulate on the weighing module and at the connection point of the vibrating feeder. On the other hand, the original module circuit board is not properly sealed, allowing humid air in the environment to easily enter the box, resulting in highly unstable weighing data. This requires frequent maintenance or replacement of the circuit board, increasing costs.

[0004] In addition, the weighing module contains a heat source, which will cause the temperature to rise during continuous operation, thereby exacerbating the zero-point drift of the sensor and resulting in poor heat dissipation. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor sealing and moisture accumulation in the weighing module used for yeast production in the prior art, as well as the poor heat dissipation of the weighing module, and to propose an installation structure for the weighing module of the oscillating feeder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation structure for a vibrating feeder weighing module includes a vibrating feeder and a weighing module, wherein the vibrating feeder includes a vibrating table and a bottom support.

[0008] The weighing module is fixed to the bracket by a detachable installation structure. The weighing module includes a sealed metal box, and the cable interfaces on both sides of the box are provided with sealant.

[0009] The box body is equipped with a through-type inclined heat dissipation channel.

[0010] In some embodiments, the heat dissipation channel is provided with an extension ring in the circumferential direction.

[0011] In some embodiments, the detachable mounting structure includes a mounting block on the housing and two fixing plates. The two fixing plates are slidably connected by a dovetail block and a dovetail groove. A threaded rod and an adjusting nut are provided between the two fixing plates. After the cross groove head of the threaded rod moves away from the nut, the housing is adjusted to a horizontal mounting position along the bracket. A rubber pad layer is provided on the inner side of the fixing plates.

[0012] In some embodiments, the metal housing is made of stainless steel and is used to conduct heat outwards to assist in heat dissipation.

[0013] In some embodiments, the heat dissipation channel is a stainless steel metal pipe, and the heat dissipation channel is sealed to the housing.

[0014] In some embodiments, the heat dissipation channel is inclined, and the dust entering the heat dissipation channel is automatically discharged through vibration.

[0015] In some embodiments, the extension ring is located circumferentially in the heat dissipation channel and extends toward the heat source inside the housing.

[0016] In some embodiments, the heat dissipation channel is located close to the main heat source inside the box; the heat dissipation channel relies on natural convection or an external ventilation system for heat dissipation.

[0017] Compared with the prior art, the present invention provides an installation structure for a oscillating feeder weighing module, which has the following beneficial effects.

[0018] 1. This utility model, through the installation structure of the dovetail groove and threaded rod, allows for horizontal sliding adjustment of the weighing module's installation position and angle, or equipment replacement, without the need for opening holes in the bracket. This improves installation flexibility and convenience. Furthermore, the lateral installation reduces water accumulation near the weighing module after cleaning, minimizing the impact of moisture on the module. The rubber pad reduces the connection gap between the fixing plate and the bracket, enhancing connection stability, while also creating a flexible connection to isolate the effects of equipment vibration, thus improving the stability of weighing data. The sealant at the cable interface isolates the inside and outside of the box, preventing the ingress of humid air and water, maintaining a dry interior, ensuring stable weighing data, and reducing the frequency of circuit board repairs.

[0019] 2. This utility model utilizes stainless steel for the housing and incorporates heat dissipation channels. Heat exchange, natural convection, or a GMP-compliant ventilation system are employed to dissipate heat, preventing excessive internal temperatures that could cause sensor data drift. The heat dissipation channels feature circumferential extension rings or increased diameters to enhance heat transfer efficiency and specifically target heat sources within the housing. The inclined design of the heat dissipation channels utilizes a vibrating feeder to expel dust, preventing dust accumulation and caking that could hinder heat dissipation and exacerbate localized temperature buildup.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-2An installation structure for a vibrating feeder weighing module includes a vibrating feeder 1 and a weighing module 2. The vibrating feeder 1 includes a vibrating table 101, a support 102 at the bottom of the vibrating table 101, and a roller 103 and a positioning leg 104 at the bottom of the support 102.

[0033] The weighing module 2 is located on the lower side beam of the vibrating feeder 1. Specifically, the weighing module 2 is fixedly installed on the bracket 102.

[0034] The bracket 102 has a first threaded hole, and the weighing module 2 has mounting ears 2011 on both sides. The mounting ears 2011 have a second threaded hole in the middle that corresponds to the first threaded hole. The first threaded hole and the second threaded hole have screws inside.

[0035] In use, mounting ears 2011 with second threaded holes are welded onto the weighing module 2. According to the required installation position of the weighing module 2, first threaded holes are opened on the bracket 102. There are two first threaded holes and two second threaded holes, and the two first threaded holes correspond to the second threaded holes respectively.

[0036] A vibration motor is installed inside the vibration table 101. When the vibration motor is powered on, the vibration table 101 vibrates and is transmitted to the material (yeast powder or culture medium granules) on the vibration table 101. This breaks down the friction and adhesion between the materials, allowing the materials to overcome gravity and slide down evenly. Under the action of vibration, the materials move downward along the tilt angle of the vibration table 101 and enter the subsequent process.

[0037] like Figure 1-5 As shown, mounting blocks 202 are fixedly connected to the top and bottom of the side of the box 201 near the bracket 102. A dovetail groove 2021 is provided in the middle of the mounting block 202. A dovetail block 2023 is slidably connected inside the dovetail groove 2021. A fixing clamp 2024 is fixedly connected to the dovetail block 2023. A mounting groove 2025 is provided on the side of the two fixing clamps 2024 that are far away from each other. A threaded rod 2026 is provided inside one mounting groove 2025. The threaded section of the threaded rod 2026 passes through the two mounting grooves 2025. A nut 2027 is threadedly connected to the end of the threaded rod 2026 that is far away from the cross groove head.

[0038] The inner sides of the two fixed clamps 2024 are provided with rubber pads. The rubber pads are used to reduce the connection gap between the fixed clamps 2024 and the bracket 102, improve the stability of the connection between the fixed clamps 2024 and the bracket 102, and at the same time, the rubber pads can form a flexible connection between the fixed clamps 2024 and the bracket 102, while ensuring the strength of the installation connection and appropriately isolating the vibration impact during equipment operation.

[0039] During use, there is no need to drill holes in the bracket 102. By screwing the threaded rod 2026, the nut 2027 and the cross groove head of the threaded rod 2026 are moved away from each other. At the same time, the two fixing plates 2024 slide away through the two dovetail grooves 2021, allowing the box 201 to slide horizontally along the bracket 102 to adjust its installation position. This allows the box 201 to be installed on the side of the bracket 102, making it less likely for water to accumulate on the box 201 and the bracket 102 after cleaning.

[0040] By keeping the nut 2027 stationary and continuing to tighten the threaded rod 2026, the nut 2027 and the threaded rod 2026 can be disengaged. At this time, the threaded rod 2026 can be removed from the mounting slot 2025, allowing the box 201 to be installed in other positions of the bracket 102, on other equipment, or disassembled for maintenance, thereby improving the flexibility and convenience of use.

[0041] Because the GMP room used for yeast production requires frequent cleaning, it is often kept dark and humid. The original structure of weighing module 2 is not well-sealed, allowing humid air to easily enter the box, resulting in unstable weighing data. When used in the GMP room, it often requires maintenance or circuit board replacement, increasing maintenance and operating costs. The following improvements are proposed to address this issue:

[0042] The weighing module 2 includes a housing 201. Cable interfaces are provided on both sides of the housing 201. The cable interfaces are used to connect the wiring to the circuit board inside the housing 201. Sealant is provided at the connection between the cable interface and the wiring. The sealant is used to isolate the inside and outside of the housing 201, preventing external water or humid air from entering the housing 201, thereby keeping the inside of the housing 201 dry for a long time, ensuring the stability of the weighing display data, and reducing the number of times the circuit board inside the housing 201 needs maintenance.

[0043] like Figure 6-8 As shown, since the circuit board inside the housing 201 also includes heat sources such as a signal processor and a power supply, in actual use, users have found that the internal temperature of the housing 201 gradually increases when it is sealed, especially the weighing module 2 when it is in continuous operation. The heat dissipation efficiency is low, which may cause the sensor detection data in the weighing module 2 to drift. The following embodiment is provided to solve the above problem:

[0044] The housing 201 is made of stainless steel, and heat dissipation is achieved through heat exchange between the housing 201 and the external low-temperature gas. Furthermore, a heat dissipation channel 3 is provided on the housing 201. The heat dissipation channel 3 includes an opening in the housing 201 and a heat dissipation channel 3 itself. The opening and the heat dissipation channel 3 are sealed and fixed together. The heat dissipation channel 3 directly penetrates the housing 201. The heat dissipation channel 3 itself can be made of stainless steel. As a ventilation channel, airflow passes through the heat dissipation channel 3 and exchanges heat with its inner wall, carrying away the heat inside the channel and expelling it outwards. The generation of the cooling airflow relies on natural air convection or the ventilation system of the GMP room.

[0045] Furthermore, an extension ring 301 is provided circumferentially in the heat dissipation channel 3. The extension ring 301 increases the heat dissipation area between the heat dissipation channel 3 and the housing 201. The extension ring 301 is used to improve the heat transfer efficiency from the housing 201 to the heat dissipation channel 3. The heat dissipation channel 3 is close to the heat source inside the housing 201, providing targeted heat dissipation to the heat source inside the housing 201. Optionally, the extension ring 301 can be replaced by increasing the diameter of the heat dissipation channel 3, depending on the application requirements.

[0046] The heat dissipation channel 3 is set at an angle. After the dust enters the heat dissipation channel 3, when the vibrating feeder 1 is started, the dust entering the heat dissipation channel 3 is moved downward and discharged by the vibration energy of the vibrating feeder 1, so as to avoid too much dust accumulating in the heat dissipation channel 3 and being plated in the heat dissipation channel 3 due to contact with moisture, which would affect heat dissipation or aggravate the local temperature accumulation in the box 201.
