Abstract
Description
Technical Field
[0001] This utility model relates to the field of vending machine technology, and in particular to a material drop protection structure for a beverage vending machine. Background Technology
[0002] In existing beverage vending machines, the impact force is often significant when beverages fall from the shelf to the dispensing slot due to the lack of an effective cushioning structure. This impact not only easily causes carbonated beverages (such as carbonated drinks) to accidentally open due to vibration, affecting the user experience, but also presents the following problems:
[0003] 1. Noise problem: Beverages hitting metal or hard structures directly can generate significant noise, especially in public places, which can negatively impact the environment.
[0004] 2. Insufficient stability: Traditional free-fall feeding method is prone to causing beverages to spill or get stuck, resulting in poor product retrieval;
[0005] While existing technologies attempt to cushion the impact with springs or pads, their simple structure and limited cushioning effect make it difficult to balance stability and rapid recovery.
[0006] Therefore, it is necessary to provide a new material drop protection structure for beverage vending machines to solve the above-mentioned technical problems. Utility Model Content
[0007] To solve the above-mentioned technical problems, this utility model provides a material drop protection structure for beverage vending machines.
[0008] The present invention provides a material drop protection structure for a beverage vending machine. The vending machine has a shelf for storing and dispensing materials, and a material drop protection structure is installed inside the vending machine below the shelf. The material drop protection structure includes a mounting frame, on which a bracket is fixedly installed. Two rotatably connected and vertically distributed rollers are mounted on the bracket, and an annular belt is installed between the two rollers.
[0009] A loading arc plate is fixedly installed on the side of the annular belt near the vending machine's outlet, and a counterweight plate is fixedly installed on the side of the annular belt away from the vending machine's outlet.
[0010] The mounting frame is also equipped with auxiliary components, including two uprights. The two uprights are fixedly installed on the mounting frame and symmetrically distributed. The two uprights pass through two through holes in the counterweight plate and are slidably connected to the through holes. Each upright has a rod cap fixedly installed at the top and a spring sleeved on the upright.
[0011] Preferably, one end of the spring is fixedly connected to the inner top wall of the rod cap.
[0012] Preferably, the loading arc plate is provided with a material-dispensing arc plate, and side frames are fixedly installed on both sides of the material-dispensing arc plate. A rotating shaft is rotatably connected to the connecting end of the side frame, and a sliding column is fixedly installed at the connecting end of the rotating shaft.
[0013] The sliding columns on both sides of the feeding arc plate are respectively inserted into the sliding grooves opened in the two brackets and are slidably connected to the sliding grooves.
[0014] Preferably, the side cross-section of the loading arc plate is a semi-circular structure, the side cross-section of the material-dispensing arc plate is a quarter-circular structure, and the material-dispensing arc plate falls inside the loading arc plate.
[0015] Preferably, a rubber pad is fixedly embedded at the bottom of the feeding arc plate.
[0016] Preferably, a lifting column for lifting the side frame is fixedly installed on the side wall near the bottom of the bracket.
[0017] Preferably, the mounting bracket is fixedly installed in the vending machine below the shelf.
[0018] Compared with related technologies, the material drop protection structure for beverage vending machines provided by this utility model has the following beneficial effects:
[0019] This invention utilizes the synergistic effect of a counterweight plate and a spring to quickly absorb the weight of the beverage during its initial fall, and then slows down the speed through spring compression, achieving multi-stage buffering. This effectively reduces impact and noise, thus providing effective cushioning for dropped beverages. It prevents the beverage from vibrating due to the impact with the bottom of the dispenser, which could cause inconvenience in opening the lid, especially for carbonated beverages. It also reduces the noise generated by the impact between the beverage and the vending machine. After the beverage is removed from the loading plate, the loading plate quickly returns to its original position under the action of the spring and counterweight plate. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0027] Please see Figures 1 to 5 This utility model provides a material drop protection structure for a beverage vending machine. The vending machine 100 has a shelf 200 installed inside for storing and dispensing materials, and the vending machine 100 is equipped with a material drop protection structure inside the shelf 200.
[0028] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The material drop protection structure includes a mounting frame 1, which is fixedly installed in the vending machine 100 below the shelf 200. A bracket 2 is fixedly installed on the mounting frame 1, and two rotatably connected and vertically distributed rollers 3 are mounted on the bracket 2. An annular belt 4 is installed between the two rollers 3. A loading arc plate 5 is fixedly installed on the side of the annular belt 4 near the discharge port of the vending machine 100, and a counterweight plate 6 is fixedly installed on the side of the annular belt 4 away from the discharge port of the vending machine 100.
[0029] The mounting frame 1 is also equipped with an auxiliary component 7, which includes two uprights 71. The two uprights 71 are fixedly installed on the mounting frame 1 and are symmetrically distributed. The two uprights 71 pass through two through holes opened in the counterweight plate 6 and are slidably connected to the through holes. Each upright 71 has a rod cap 72 fixedly installed on its top, and a spring 73 is sleeved on the upright 71. One end of the spring 73 is fixedly connected to the inner top wall of the rod cap 72.
[0030] It should be noted that: because a counterweight plate 6 is installed on the side of the annular belt 4 away from the dispensing port of the vending machine 100, when there is no beverage falling on the shelf 200, the loading arc plate 5, under the action of the counterweight plate 6, rises with the annular belt 4 to the highest point and approaches the bottom of the dispensing port of the shelf 200.
[0031] When a beverage falls from the shelf 200 onto the loading arc plate 5, the loading arc plate 5 is driven to descend by the weight of the beverage and drives the counterweight plate 6 to slide up the upright 71 via the ring belt 4.
[0032] When the counterweight plate 6 is not in contact with the spring 73, the loading arc plate 5 descends at a relatively fast speed. After the counterweight plate 6 comes into contact with the spring 73, the spring 73 is compressed, which also reduces the downward speed of the loading arc plate 5. Therefore, it effectively catches and cushions the beverage that falls, avoiding the problem of the beverage being difficult to open due to the large impact with the bottom of the box at the dispensing port. It also reduces the noise generated by the impact between the beverage and the vending machine 100. When the beverage is taken out of the loading arc plate 5, the loading arc plate 5 quickly returns to its original position under the action of the spring 73 and the counterweight plate 6.
[0033] In this embodiment: to avoid the risk of slippage between the annular belt 4 and the two rollers 3, the annular belt 4 can be replaced with an annular belt with a built-in flexible toothed belt, and the two rollers 3 can be replaced with gears, thereby effectively solving the problem of slippage between the annular belt 4 and the two rollers 3.
[0034] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 5 The loading arc plate 5 is provided with a material-pushing arc plate 8, and side frames 81 are fixedly installed on both sides of the material-pushing arc plate 8. The connecting end of the side frame 81 is equipped with a rotating shaft 82 that is rotatably connected, and the connecting end of the rotating shaft 82 is fixedly installed with a sliding column 83. The sliding columns 83 on both sides of the material-pushing arc plate 8 are respectively inserted into the sliding grooves 2a opened in the two supports 2 and are slidably connected to the sliding grooves 2a. The side wall of the support 2 near the bottom is fixedly installed with a lifting column 9 for lifting the side frame 81.
[0035] It should be noted that when a beverage falls from the shelf 200 onto the feeding arc plate 5 and then onto the dispensing arc plate 8, the feeding arc plate 5 falls to the lowest point of the support 2. At this time, the lifting column 9 lifts the side frame 81, causing the dispensing arc plate 8 to lift up and slide out of the feeding arc plate 5. At this time, the beverage in the dispensing arc plate 8 can quickly slide out of the dispensing arc plate 8 and roll to the dispensing port of the vending machine 100.
[0036] Furthermore, the side cross-section of the loading arc plate 5 is a semi-circular structure, and the side cross-section of the dispensing arc plate 8 is a quarter-circular structure. The dispensing arc plate 8 is placed inside the loading arc plate 5. Thus, when the dispensing arc plate 8 is placed inside the loading arc plate 5, the beverage cannot slide outward under the restriction of the loading arc plate 5. However, when the dispensing arc plate 8 is moved and slides outward from the dispensing arc plate 8, the beverage inside the dispensing arc plate 8 can slide outward from the dispensing arc plate 8 to the dispensing port after the restriction of the loading arc plate 5 is removed.
[0037] Furthermore, a rubber pad is fixedly embedded at the bottom of the feeding arc plate 8 to reduce the impact between the loading arc plate 5 and the feeding arc plate 8.
[0038] In this application, the counterweight plate 6 and the spring 73 work together to quickly absorb the gravity in the early stage of the beverage falling, and then the spring 73 is compressed to slow down the speed, thus achieving multi-stage buffering and effectively reducing impact and noise. By utilizing the gravity of the counterweight plate 6 and the rebound force of the spring 73, the loading arc plate 5 can quickly return to the initial position after the beverage is taken out, thereby improving the continuous discharge efficiency.
[0039] The working principle of the material drop protection structure for beverage vending machines provided by this utility model is as follows:
[0040] Because a counterweight plate 6 is installed on the side of the annular belt 4 away from the dispensing port of the vending machine 100, when there is no beverage falling on the shelf 200, the loading arc plate 5, under the action of the counterweight plate 6, rises with the annular belt 4 to the highest point and approaches the bottom of the dispensing port of the shelf 200; when a beverage falls onto the loading arc plate 5 on the shelf 200, the loading arc plate 5 is driven to descend by the weight of the beverage and drives the counterweight plate 6 to slide up along the upright 71 via the annular belt 4.
[0041] When the counterweight plate 6 is not in contact with the spring 73, the loading arc plate 5 descends relatively quickly. After the counterweight plate 6 contacts the spring 73, the spring 73 is compressed, which also reduces the downward speed of the loading arc plate 5. Therefore, it effectively catches and cushions the beverage that falls, avoiding the problem of the beverage being difficult to open due to the large impact with the bottom of the box at the dispensing port when it is dispensed. It also reduces the noise generated by the impact between the beverage and the vending machine 100. When a beverage falls from the shelf 200 onto the feeding arc plate 8 in the loading arc plate 5, the loading arc plate 5 falls to the lowest point of the support 2. At this time, the lifting column 9 lifts the side frame 81, so that the feeding arc plate 8 lifts up and slides out of the loading arc plate 5. At this time, the beverage in the feeding arc plate 8 can quickly slide out of the feeding arc plate 8 and roll to the dispensing port of the vending machine 100. When the beverage is taken out of the loading arc plate 5, the loading arc plate 5 quickly returns to its original position under the action of the spring 73 and the counterweight plate 6.
[0042] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
