Description

Technical Field

[0001] This utility model relates to the field of bowl-type lifting machinery technology, specifically to a bowl-type fixing device for quantitative food conveying. Background Technology

[0002] In automated production lines in industries such as food and chemicals, quantitative bowl elevators are a key type of conveying equipment. They utilize bowl-shaped containers (such as...) fixed to a conveyor chain... Figure 1 As shown in the image, this equipment enables precise metering, vertical lifting, and horizontal conveying of granular, powdery, or lumpy materials. This ensures stable and continuous material flow between workstations, playing a crucial role in guaranteeing production efficiency, metering accuracy, and hygiene and safety during the production process. Therefore, the performance of the bowl-shaped fixing device, its core component, directly determines the reliability, efficiency, and service life of the entire conveying system.

[0003] Currently, there are various devices in the prior art for fixing bowl-shaped containers. For example, Chinese Utility Model Patent Publication No. CN221458885U discloses a bowl-shaped clamping device, which includes a base plate, a limiting block located on the base plate, and a clamping block hinged to the base plate via a rotating column. This device manually rotates the clamping block to make it contact one side of the bowl-shaped material trough, and then uses an independent positioning component (including a pull block, a pin, and a return spring) to lock the clamping block, thereby cooperating with the limiting block on the other side to clamp the bowl-shaped material trough onto the base plate.

[0004] However, the existing bowl-type clamping device still has significant drawbacks. First, its clamping and releasing process is cumbersome and cannot achieve rapid automatic clamping. Each operation requires manual execution of multiple steps: "pulling the lever - rotating the clamping block - releasing the lever to lock the pin in place." This consumes considerable time during the initial installation of the measuring bowl, resulting in low installation efficiency and preventing the equipment from being put into use quickly. Second, the clamping force of this device is not adaptively adjustable. For measuring bowls of different sizes or with manufacturing tolerances, it lacks effective error tolerance, which may lead to the bowls being clamped too loosely and falling off, or clamped too tightly and damaging the bowls. Utility Model Content

[0005] The present invention aims to provide a bowl-type fixing device for quantitative food delivery, so as to solve the problem that the clamping mechanism in the prior art has a fixed size and therefore cannot adapt to quantitative bowls of various sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bowl-type fixing device for quantitative food delivery includes a base plate and a clamping device. The clamping device is rotatably mounted on the base plate and includes two sets of pressure plates connected by elastic members. The two sets of pressure plates are arranged opposite each other and form receiving holes for fixing the quantitative bowls. An adjustment groove is formed on the base plate. One end of each set of pressure plates is mounted on the base plate by a fixing member, and the other end is swayably mounted in the adjustment groove about the fixing member as an axis. The other end of the pressure plate is locked by a locking member, and the two ends of the elastic member are respectively mounted on the locking member. A gap is provided between the pressure plate and the base plate for engaging the bottom engaging part of the quantitative bowl.

[0007] Beneficial effects: 1. Two sets of pressure plates provide pre-tightening force through elastic elements. Since the arrangement of the fixing devices is symmetrical about the center line of the receiving hole, and the tension of the elastic elements on the two pressure plates is always equal, the device is balanced only when the central axis of the metering bowl coincides with the central axis of the receiving hole, thereby achieving automatic centering and adaptive clamping. When the bowl is placed, the pressure plates automatically open and automatically clamp after placement, which can adapt to the small manufacturing tolerances of the bowl and provide stable and flexible clamping force to prevent loosening due to vibration during transportation.

[0008] 2. The gap between the pressure plate and the base plate can be locked to the bottom locking part of the measuring bowl. With the pre-tightening force of the elastic element and the locking effect of the locking element, the measuring bowl can be fixed from the side and bottom, preventing shaking, tipping or shifting during the conveying process. Especially when flipping and pouring out food, it can effectively prevent the bowl from falling off completely, ensuring the absolute safety of the entire process.

[0009] 3. The pressure plate can swing around the fixing member and adjust its position along the adjustment groove. Combined with the elasticity of the elastic member and the automatic clamping function, the device can adapt to the metering bowls of different diameters without the need to replace the special fixing structure.

[0010] Preferably, as an improvement, both sets of pressure plates are provided with a pull plate for removing the measuring bowl on the side away from the receiving hole.

[0011] Beneficial effects: The pull plate provides a clear point of force application. Operators do not need to remove the clamps; they can simply pull the pull plate to open the pressure plate and remove the bowls, which greatly improves the speed of operation and reduces labor intensity.

[0012] Preferably, as an improvement, the pull plate and the pressure plate are integrally formed.

[0013] Beneficial effects: The one-piece molding structure eliminates the defects of welding or bolted connections, making the structure more robust and durable, and it will not loosen or be damaged due to repeated operation; at the same time, it reduces the number of parts and assembly steps.

[0014] Preferably, as an improvement, mounting portions for fixing the base plate are provided on both sides of the base plate.

[0015] Beneficial effects: The design of the mounting section allows the fixing device to be installed as an independent module, which can be quickly and easily installed on existing conveyor chains or transmission systems, improving the modularity of the equipment and facilitating installation, maintenance and replacement.

[0016] Preferably, as an improvement, the bottom plate is provided with a first clearance groove at the end near the mounting part, and with second clearance grooves on both sides away from the mounting part.

[0017] Beneficial effects: The first clearance groove ensures that there will be no collision with the central guide rail during the lifting section, and the second clearance groove ensures that there will be no interference with the support frames on both sides during the flipping or return, thereby ensuring that the entire conveying system can operate smoothly and without interruption, avoiding downtime, jamming or component damage caused by structural interference, and improving the reliability of the entire system.

[0018] Preferably, as an improvement, a roller is provided at the bottom of the base plate near the first clearance groove, and a connector is installed on the base plate, with the roller rotatably connected to the connector.

[0019] Beneficial effects: It transforms the sliding friction between the base plate and the guide rail into rolling friction, which greatly reduces the traction load on the chain, prevents overload, wear and breakage of the chain and motor, and extends the core life of the entire conveying system.

[0020] Preferably, as an improvement, the locking element includes a pressure plate and bolts. The pressure plate is fixedly connected above the pressure plate by bolts, and washers are provided between the pressure plate and the base plate, as well as at the bottom of the base plate.

[0021] Beneficial effects: By pressing the pressure plate onto the pressure plate, since the outer diameter of the pressure plate is larger than the diameter of the bolt, the pressure plate can provide a larger pressing area, making the locking force distribution more uniform, and thus making the pressure plate more secure in fixing the metering bowl.

Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figures 1-5 As shown: This embodiment provides a bowl-type fixing device for quantitative food delivery, wherein the quantitative bowl 1 is as follows: Figure 1 As shown, the measuring bowl 1 includes a main body and a snap-fit ​​part 11 located at the bottom of the main body, the main body and the snap-fit ​​part 11 being integrally formed; as Figure 2 As shown, the bowl fixing device includes a base plate 2 and a clamping device for clamping the measuring bowl 1. The clamping device is rotatably mounted on the base plate 2, as shown below. Figure 3 As shown, mounting portions 24 for fixing the base plate 2 are provided on both sides of the base plate 2. Specifically, the mounting portions 24 are connected to the chain of the quantitative conveying device by bolts and nuts, so that the chain can drive the base plate 2 to move during the movement. A first clearance groove 22 is provided at one end of the base plate 2 near the mounting portion 24, and a second clearance groove 22 is provided on both sides away from the mounting portion 24. The first clearance groove 22 is used to prevent the base plate 2 from interfering with the guide rail provided in the middle of the conveying device during the rising process. The second clearance groove 22 is used to prevent the device from interfering with the support surfaces on both sides of the conveying device after the device is flipped and retracted. A roller 4 is provided at the bottom of the base plate 2 near the first clearance groove 22. A connecting piece is installed on the base plate 2, and the roller 4 is rotatably connected to the connecting piece, so that when the chain drives the entire device to move, the previous sliding friction is converted into rolling friction, thereby effectively reducing the running resistance and playing the role of lubricating and protecting the chain.

[0029] like Figure 3 and Figure 4As shown, the clamping device includes two sets of pressure plates 31. The two sets of pressure plates 31 are arranged opposite each other and have receiving holes 311 for fixing the measuring bowl 1. Each set of pressure plates 31 has a pull plate 312 for removing the measuring bowl 1 on the side away from the receiving hole 311, and the pull plate 312 is integrally formed with the pressure plate 31. An adjustment groove 21 is formed on the base plate 2. One end of each set of pressure plates 31 is mounted on the base plate 2 by a fixing member 33, and the other end is swayably mounted in the adjustment groove 21 with the fixing member 33 as the axis. The other end of the pressure plate 31 is locked by a locking member 34. The locking member 34 includes a pressure plate 341 and a bolt. The pressure plate 341 is fixedly connected to the top of the pressure plate 31 by the bolt. Washers 342 are provided between the pressure plate 31 and the base plate 2 and at the bottom of the base plate 2. In this embodiment, the fastener 33 is also a bolt, and a washer 342 is provided between the base plate 2 and the pressure plate 31. The washer 342 and the washer 342 of the locking member 34 are both made of rubber.

[0030] like Figure 5 As shown, to achieve adaptive clamping of the fixing device, the two sets of pressure plates 31 are connected by elastic elements 32. Specifically, the elastic elements 32 are springs and are located at the bottom of the base plate 2. The two ends of the elastic elements 32 are respectively installed on the locking elements 34, so that when the measuring bowl 1 containing food is placed into the receiving hole 311, the pressure plates 31 on both sides can extend outward along the adjusting groove 21 under the action of the elastic elements 32, so as to facilitate the placement of the measuring bowl 1. After placement, the elastic elements 32 contract and can drive the pressure plates 31 on both sides to squeeze inward, thereby achieving clamping.

[0031] To prevent the measuring bowl 1 from falling off the clamping device when food is poured out, a gap is provided between the pressure plate 31 and the bottom plate 2 for locking the bottom locking part 11 of the measuring bowl 1; and to facilitate the insertion of the measuring bowl 1, the opposite ends of the two sets of pressure plates 31 near the roller 4 are formed with openings for pushing the measuring bowl 1 in.

[0032] The above-mentioned device is used as follows: The base plates 2 of multiple fixing devices are sequentially connected to the chain of the quantitative conveying device, which is welded with multiple connecting plates, via the mounting parts 24 on both sides. This ensures a secure installation and that the chain moves synchronously with the base plates 2. The quantitative bowl 1 is then installed on the base plate 2. Specifically, the two sets of pressure plates 31 are pushed open along both sides by pulling the pull plates 312 on both sides. The quantitative bowl 1 is then placed in the receiving hole 311 between the two sets of pressure plates 31. After the quantitative bowl 1 is fully inserted, the elastic element 32 contracts, causing the pressure plates 31 on both sides to press inward, automatically clamping the body of the quantitative bowl 1. Finally, the pressure plates 31 are locked by the locking element 34, thus completing the installation of the quantitative bowl 1. Simultaneously, the snap-fit ​​part 11 of the quantitative bowl 1 engages in the gap between the pressure plate 31 and the base plate 2, preventing the quantitative bowl 1 from falling off during conveying or tilting. The quantitative conveying device is started. At this time, the weighed food is poured into the quantitative bowl 1, so that the quantitative bowl 1 and the fixing device move along the predetermined track under the action of the chain. The food in the quantitative bowl 1 is then conveyed to the turning point for turning, and the food in the bowl is poured out. After the food is poured out, the quantitative bowl 1 is returned to the initial point under the action of the chain, so that the operator can pour the weighed food back into the quantitative bowl 1. During the turning process, the bottom of the quantitative bowl 1 is locked and fixed, so that the bowl will not fall off the fixing device after the turning. During the movement of the quantitative bowl 1, since the conveying device needs to move the bowl to a higher position, the first clearance groove 22 of the base plate 2 can avoid interference with the guide rail in the middle of the conveying device during the rising process. The second clearance groove 22 can avoid interference with the support surfaces on both sides of the conveying device when the device is turned and retrieved. The rollers 4 installed on the base plate 2 roll on the guide rail, reducing the running resistance, reducing the chain load, and thus protecting the chain.
