Description

TECHNICAL FIELD

[0001] The utility model relates to the popcorn production technical field especially is popcorn cup automatic cup device of subpackaging cup. BACKGROUND

[0002] Popcorn has formed a large-scale consumption scene as a leisure food, and subpackaging cups are commonly used for quantitative packaging in places such as cinemas and convenience stores. The traditional subpackaging process relies on manual cup separation, which is inefficient and has hygiene risks. With the popularization of automatic equipment, some cup separating devices begin to use mechanical separation structures. The existing technology often uses a spring push rod type cup separating mechanism that releases stacked cups step by step through elastic elements. However, such devices are sensitive to cup deformation. When the subpackaging cup is slightly deformed due to material quality or stacking pressure, it is easy to cause jamming or double-cup adhesion. There is also a scheme of using a pneumatic cup separating system that separates cups by air flow disturbance, but it has high energy consumption and strict requirements for cup mouth sealing, making it difficult to adapt to open subpackaging environments.

[0003] The current popcorn subpackaging industry is developing towards high speed and flexibility, and the promotion and application of new degradable material cups have higher requirements for cup separating devices. Subpackaging cups are usually designed in an inverted conical frustum shape to facilitate stacking and storage, but this shape causes the contact area between cups to change nonlinearly with the stacking height, making it difficult for traditional separating mechanisms to accurately control the single separation stroke. The industry urgently needs a cup separating device that can adapt to cup deformation and achieve controllable friction force output, ensuring the success rate of cup separation while reducing the impact on the structural integrity of the cup. In particular, in unmanned retail scenarios, the equipment needs to have compact structure, low noise operation and fast maintenance characteristics, which poses a complex technical challenge to the power transmission efficiency and stability of the transmission system. SUMMARY

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a popcorn subpackaging cup automatic cup separating device, a plurality of subpackaging cups are stacked in the cup holder, the lower end of the cup extends into the center of the composite gear, the inner side of the composite gear is provided with an inner straight tooth ring, a plurality of driven gears are evenly distributed and meshed on the inner side of the inner straight tooth ring, each driven gear is simultaneously meshed with a corresponding secondary gear, the inclined friction wheel is coaxially connected with the secondary gear, a plurality of inclined friction wheels are inclined and abut against the outer wall of the cup body along the circumference of the bottom of the subpackaging cup, the outer side of the composite gear is provided with an outer bevel gear ring, the output end of the driving motor is connected with the bevel gear, the bevel gear is meshed with the outer bevel gear ring, and the driving motor drives the rotation of the plurality of inclined friction wheels.

[0006] In a preferred embodiment, the cup-separating device includes a housing that is adapted to the outer contour of the gear transmission structure. The two ends of the first rotating shaft are fixedly connected to the upper and lower ends of the housing, respectively. The driven gear is rotatably connected to the first rotating shaft. The second rotating shaft is rotatably connected to the upper and lower ends of the housing. The secondary gear and the helical friction wheel are fixedly connected to the second rotating shaft at intervals. The driven gear meshes with the secondary gear and drives the helical friction wheel to rotate around the axis of the second rotating shaft.

[0007] In the preferred embodiment, the end face of the inclined friction wheel forms an acute angle of 15° to 75° with the horizontal plane, which is used to make adjacent dispensing cups form a predetermined distance of a certain length when they are separated.

[0008] In the preferred embodiment, the inclined friction wheel is divided into an ascending arc segment and a descending arc segment along the axis formed by the line connecting its highest and lowest points. When the inclined friction wheel rotates in a set direction, the points on the ascending arc segment and the descending arc segment form oblique upward and oblique downward motion trajectories, respectively. The axis of the second rotating shaft is offset relative to the geometric center of the inclined friction wheel towards the ascending arc segment side, so as to make the inclined friction wheel (5) disengage from the dispensing cup when it is running in the ascending arc segment.

[0009] In the preferred embodiment, the minimum diameter of the circular cavity enclosed by the inner sides of the multiple inclined friction wheels is smaller than the maximum outer diameter of the dispensing cup.

[0010] In the preferred embodiment, the outer circumference of the inclined friction wheel is provided with an elastic material layer, and its surface is provided with anti-slip texture, which is used to increase the effective contact length between the dispensing cup and the inclined friction wheel by the radial elastic deformation generated when in contact with the dispensing cup.

[0011] In the preferred embodiment, the outer circumferential edge of the composite gear is further provided with a convex ring, and the corresponding position of the inner wall of the outer shell is provided with a rotary guide groove. The composite gear is rotatably connected to the outer shell through the convex ring.

[0012] In the preferred embodiment, the cup holder includes two axially spaced connecting rings and multiple circumferentially evenly arranged support columns. Each support column extends radially inward from the lower connecting ring and connects with the upper connecting ring, then abuts against the upper outer wall of the dispensing cup. The diameter of the constraint cavity enclosed by the upper ends of the multiple support columns is smaller than the maximum outer diameter of the dispensing cup, and the difference is adapted to the elastic deformation of the dispensing cup, thereby realizing the flexible support and controllable release of the dispensing cup.

[0013] In the preferred embodiment, the drive motor is fixed to one side of the housing via a motor mount, and its output shaft passes through the side wall of the housing and is connected to a bevel gear.

[0015] This utility model provides an automatic popcorn dispensing cup dispensing device, which has the following advantages: efficient and stable cup dispensing. It adopts a composite gear transmission structure and a multi-stage gear meshing design. The drive motor drives the inclined friction wheel to rotate synchronously and apply an even oblique friction force to achieve continuous and stable separation of the dispensing cups. There is no need for frequent start-stop or complex direction control during the dispensing process, and the dispensing time per cup is shortened.

[0016] The adaptive cup body deformation is achieved by an elastic material layer and anti-slip texture on the outer circumference of the oblique friction wheel. Combined with its eccentric rotating shaft design, it can generate radial elastic deformation when in contact with the dispensing cup, increasing the effective contact length and friction force, and avoiding problems such as jamming or double cup sticking caused by slight deformation of the cup body.

[0017] Precise control of the cup spacing, the acute angle between the end face of the inclined friction wheel and the horizontal plane, combined with the motion trajectory division of the rising and falling arc segments, ensures that the cups are separated at a predetermined distance. The axis of the second rotating shaft is offset towards the rising arc segment to ensure that the inclined friction wheel disengages during the rising phase, avoiding interference with the falling of the separated cups and meeting the requirements of high-speed dispensing.

[0018] With low energy consumption and low noise, the meshing transmission structure of bevel gear and external bevel gear ring optimizes the power transmission path and reduces energy loss. The elastic contact method of the helical friction wheel reduces operating shock and vibration, making it suitable for scenarios with high requirements for quietness, such as unmanned retail.

[0019] With its compact structure and easy maintenance, the outer shell features a detachable connecting lug design for easy disassembly and maintenance; the drive motor is independently fixed on one side of the outer shell, reducing the risk of interference between transmission components; and the overall size is small, making it suitable for installation in confined spaces.

[0020] With wide compatibility, the diameter of the cavity surrounding the inner side of the inclined friction wheel is adapted to the maximum outer diameter of the dispensing cup. Combined with the deformation capability of the elastic material layer, it can be compatible with various cup shapes and is suitable for biodegradable cups and dispensing needs of different specifications.

[0021] This invention, through its innovative transmission structure and contact design, significantly reduces damage to the cup structure while improving the efficiency and success rate of cup dispensing, thus meeting the technical requirements of high-speed and flexible development in the popcorn dispensing industry.

Detailed Implementation

[0033] Example 1

[0034] like Figures 1-9 As shown, an automatic popcorn dispensing cup device is provided. Multiple dispensing cups are stacked in a cup holder 1, with their lower ends extending into the center of a compound gear 2. An inner spur gear ring 201 is provided on the inner side of the compound gear 2. Multiple driven gears 3 are evenly distributed and meshed on the inner circumferential side of the inner spur gear ring 201. Each driven gear 3 meshes with a corresponding secondary gear 4. An oblique friction wheel 5 is coaxially connected to the secondary gear 4. Multiple oblique friction wheels 5 are inclined along the bottom circumferential direction of the dispensing cup and abut against the outer wall of the cup. An outer bevel gear ring 202 is provided on the outer side of the compound gear 2. The output end of a drive motor 6 is connected to a bevel gear 7. The bevel gear 7 meshes with the outer bevel gear ring 202. The drive motor 6 drives multiple oblique friction wheels 5 to rotate, which is used to separate the popcorn dispensing cups one by one by oblique friction force.

[0035] This application adopts a multi-stage gear transmission structure. The drive motor 6 meshes with the outer bevel gear ring 202 through the bevel gear 7, causing the inner spur gear ring 201 to rotate axially. Multiple meshing driven gears 3 rotate, thereby driving the secondary gear 4 and its coaxial oblique friction wheel 5 to rotate. The multiple oblique friction wheels 5 convert the axial rotation into an equal oblique downward force uniformly applied to the circumferential contact point of the dispensing cup, thereby causing the dispensing cup to rotate and separate from the upper dispensing cup by a certain distance. This movement is subject to uniform force, allowing the dispensing cup to detach vertically and fall naturally.

[0036] In the preferred embodiment, the cup-separating device includes a housing 8 that is adapted to the outer contour of the gear transmission structure. The two ends of the first rotating shaft 9 are fixedly connected to the upper and lower ends of the housing 8, respectively. The driven gear 3 is rotatably connected to the first rotating shaft 9. The second rotating shaft 10 is rotatably connected to the upper and lower ends of the housing 8. The secondary gear 4 and the oblique friction wheel 5 are fixedly connected to the second rotating shaft 10 at intervals. The driven gear 3 meshes with the secondary gear 4, driving the oblique friction wheel 5 to rotate around the axis of the second rotating shaft 10.

[0037] In the preferred embodiment, the end face of the inclined friction wheel 5 forms an acute angle of 15° to 75° with the horizontal plane, which is used to make adjacent dispensing cups form a predetermined distance of a certain length when they are separated.

[0038] In the preferred embodiment, the inclined friction wheel 5 is divided into an ascending arc segment 501 and a descending arc segment 502 along the axis formed by the line connecting its highest and lowest points. When the inclined friction wheel 5 rotates in a set direction, the points on the ascending arc segment 501 and the descending arc segment 502 respectively form oblique upward and oblique downward motion trajectories. The axis of the second rotating shaft 10 is offset relative to the geometric center of the inclined friction wheel 5 towards the ascending arc segment 501, so as to make the inclined friction wheel (5) disengage from the dispensing cup when running in the ascending arc segment.

[0039] In the preferred embodiment, the minimum diameter of the circular cavity enclosed by the inner sides of the multiple inclined friction wheels 5 is smaller than the maximum outer diameter of the dispensing cup.

[0040] In the preferred embodiment, the outer circumference of the inclined friction wheel 5 is provided with an elastic material layer, and its surface is provided with anti-slip texture, which is used to increase the effective contact length between the dispensing cup and the inclined friction wheel 5 by the radial elastic deformation generated when in contact with the dispensing cup.

[0041] The inclined friction wheel 5 is adapted to the length required for the step-by-step separation of the dispensing cups by the angle of its end face inclination. Through its eccentric rotating shaft structure, when its descending arc segment 502 abuts against the cup wall, it generates an appropriate amount of elastic deformation, increasing the arc length of the contact part and maximizing the separation force. As the ascending arc segment 501 rotates to the inner side, the inclined friction wheel 5 disengages from the dispensing cup, avoiding affecting the falling of the dispensing cup that has not yet completely separated. If it is necessary to continue separating the next dispensing cup, it can be made to continue rotating in a certain direction. There is no need for complicated control of the rotation direction and timing. It is a separation device with reliable structure and strong separation continuity.

[0042] The combined effect of the elastic deformation and high friction coefficient of the inclined friction wheel 5 increases the reliability of the force exerted by the inclined friction wheel 5 on the dispensing cup and prevents slippage.

[0043] In the preferred embodiment, the outer circumferential edge of the composite gear 2 is further provided with a convex ring 203, and the inner wall of the outer shell 8 is provided with a corresponding rotary guide groove 801. The composite gear 2 is rotatably connected to the outer shell 8 through the convex ring 203.

[0044] In the preferred embodiment, the cup holder 1 includes two axially spaced connecting rings 101 and a plurality of circumferentially evenly arranged support columns 102. Each support column 102 extends radially inward from the lower connecting ring 101 and connects with the upper connecting ring 101, then abuts against the upper outer wall of the dispensing cup. The diameter of the constraint cavity enclosed by the upper ends of the plurality of support columns 102 is smaller than the maximum outer diameter of the dispensing cup, and the difference is adapted to the elastic deformation of the dispensing cup, thereby realizing the flexible support and controllable release of the dispensing cup.

[0045] In the preferred embodiment, the drive motor 6 is fixed to one side of the housing 8 via the motor mount 11, and its output shaft passes through the side wall of the housing 8 and is connected to the bevel gear 7.

[0046] In the preferred embodiment, the outer wall of the outer shell 8 is provided with a plurality of connecting ears 802 evenly distributed around its circumference, which are connected to the outer frame by locking bolts 803 to form a detachable connection structure.

[0047] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
