Description

Technical Field

[0001] This utility model relates to an elliptical track spiral conveyor device, belonging to the field of spiral freezing and steaming / baking. Background Technology

[0002] Screw conveyors are energy-saving and fast conveying devices with compact structure, wide applicability, small footprint, and large transmission capacity.

[0003] Currently available screw conveyor devices are all ring-shaped, with short conveying times. For screw conveyors requiring longer conveying times, the diameter of the ring needs to be increased, as does the number of screw layers. This increases the required motor power, introduces errors in the rotation ratio, and makes them prone to damage. Furthermore, all single-screw conveyors operate with either bottom-in / top-out or top-in / bottom-out configurations, resulting in height differences. Double-screw conveyors, on the other hand, require a larger diameter and more layers, necessitating multiple geared motors, increasing operating power, and requiring a larger footprint. Both single and double-screw devices are not ideal for practical applications. Summary of the Invention

[0004] Based on the problems described in the background, the present invention aims to solve the following problems: It provides an elliptical track spiral conveyor device, an elliptical cross spiral conveyor device, where material inlet and outlet are both at the bottom, the distance between the straight segment and the arc segment is equal, and the distance of the straight segment can be lengthened. It uses only one motor, has a stable transmission ratio, and avoids transmission imbalance. This solves the problems mentioned above, such as short conveying time, errors in the rotation ratio leading to easy damage, and height differences. Simultaneously, it addresses the issues of installed power, usable space, and floor area of ​​current single-spiral and double-spiral conveyors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An elliptical track spiral conveyor device is provided, comprising a support frame, a feeding upward friction slide, a discharging downward friction slide, a horizontal transmission component, and a vertical transmission component.

[0009] Preferably, the straight and arc portions of the elliptical friction tracks, including the spiral ascending and spiral descending friction tracks, are of equal length.

[0010] Preferably, the horizontal transmission assembly includes a horizontal transmission frame, a motor, a reducer, a coupling, a steering gear, and an intermediate support frame. The horizontal transmission frame is located above the feed rising friction slide and the discharge falling friction slide. An intermediate support frame is located in the middle of the horizontal transmission frame. The projected view of the horizontal transmission frame is a right-angled U-shape. The motor and reducer are installed in the middle position of the right-angled U-shape of the horizontal transmission frame. The output end of the motor is connected to the reducer. The output end of the reducer is in the path direction of both sides of the horizontal transmission frame and is connected to the coupling respectively. The output end of the coupling is connected to the steering gear, and the steering gear is located at the right angle of the right-angled U-shape of the horizontal transmission frame. The output end of the steering gear is connected to another set of couplings and then connected to another set of steering gears. The position of the other set of steering gears is located at the end point of the right-angled U-shape of the horizontal transmission frame.

[0011] Preferably, the right-angle position and end point of the right-angle U-shape of the horizontal transmission frame are located outside the intersection of the straight line and the arc of the feeding rising friction slide and the discharging falling friction slide.

Detailed Implementation

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0026] Example 1

[0027] like Figure 1As shown, this utility model includes a support frame 1, a feeding rising friction slide 2, a discharging falling friction slide 3, a horizontal transmission component 4, and a vertical transmission component 5. The feeding rising friction slide 2 and the discharging falling friction slide 3 are installed on the support frame 1. Both the feeding rising friction slide 2 and the discharging falling friction slide 3 are elliptical spiral friction slides with intersecting spirals. The ellipse is equipped with a freezing or steaming / baking component. The horizontal transmission component 4 and the vertical transmission component 5 are installed on the top and side of the feeding rising friction slide 2 and the discharging falling friction slide 3, respectively. There are four sets of vertical transmission components 5, which are located on the outside of the intersection of the straight line and the arc of the feeding rising friction slide 2 and the discharging falling friction slide 3, and are respectively connected to the horizontal transmission component 4.

[0028] Goods that need to be loaded and unloaded are all loaded onto pallets with toothed edges.

[0029] Goods enter the pallet through the feeding rising friction slide 2. The horizontal transmission component 4 transmits power to the vertical transmission component 5, which in turn transmits power to the pallet, sliding it from the feeding rising friction slide 2 to the discharging falling friction slide 3, where it is discharged. During this process, the goods rise and fall simultaneously, allowing for longer freezing or steaming / baking times and better freezing and steaming / baking effects. Since both feeding and discharging occur at the bottom, there is no height difference, which is beneficial for use.

[0030] like Figures 2-5 As shown, the feeding rising friction slide 2 includes a feeding friction slide 21, a spiral rising friction slide 22, and a first S-shaped connecting friction slide 23. The rising friction slide 2 is a straight friction slide and is located at the bottom of the support frame 1. The rising friction slide 2 is connected to the spiral rising friction slide 22. The spiral rising friction slide 22 is an elliptical spiral friction slide and rises spirally. The first S-shaped connecting friction slide 23 is an S-shaped friction slide and is connected to the rising tail of the spiral rising friction slide 22.

[0031] The discharge descent friction slide 3 includes a discharge friction slide 31, a spiral descent friction slide 32, and a second S-shaped connecting friction slide 33. The discharge friction slide 31 is a straight friction slide and is located at the bottom of the support frame 1. The spiral descent friction slide 32 is an elliptical spiral friction slide that descends spirally. The second S-shaped connecting friction slide 33 is an S-shaped friction slide that connects the descending tail of the spiral descent friction slide 32 and the discharge friction slide 31.

[0032] The first S-shaped connecting friction slide 23 is also connected to the descending head of the spiral descending friction slide 32.

[0033] The straight and arc portions of the elliptical friction tracks 22 and 32 are of equal length.

[0034] Goods enter the feeding friction chute 21 on the pallet, then ascend and spiral through the spiral rising friction chute 22, and slide onto the spiral descending friction chute 32 via the first S-shaped connecting friction chute 23. After descending and spiraling, they slide onto the discharge friction chute 31 via the second S-shaped connecting friction chute 33, completing the entire feeding and discharging operation. Because the straight and arc sections of the elliptical friction chute 22 and spiral descending friction chute 32 are of equal length, the amount of goods to be driven is the same, and the driving power is the same. When it is necessary to increase the freezing time, the length of the straight section can be increased to increase the freezing efficiency. At the same time, the use of cross spirals solves the space and floor space problems of traditional single and double spirals, and can be modified according to the site conditions.

[0035] like Figures 2-5 As shown, the horizontal transmission assembly 4 includes a horizontal transmission frame 41, a motor 42, a reducer 43, a coupling 44, a steering gear 45, and an intermediate support frame 46. The horizontal transmission frame 41 is located above the feed rising friction slide 2 and the discharge falling friction slide 3. An intermediate support frame 46 is located in the middle of the horizontal transmission frame 41. The projected view of the horizontal transmission frame 41 is a right-angled U-shape. The motor 42 and the reducer 43 are installed in the middle of the right-angled U-shape of the horizontal transmission frame 41. The output end of the motor 42 is connected to the reducer 43. The output ends of the reducer 43 are on both sides of the horizontal transmission frame 41 and are respectively connected to the couplings 44. The output end of the couplings 44 is connected to the steering gear 45, and the steering gear 45 is located at the right angle of the right-angled U-shape of the horizontal transmission frame 41. The output end of the steering gear 45 is connected to another set of couplings 44 and then to another set of steering gears 45. The other set of steering gears 45 is located at the end of the right-angled U-shape of the horizontal transmission frame 41.

[0036] The right-angle position and end point of the right-angle U-shaped horizontal transmission frame 41 are located outside the intersection of the straight line and the arc of the feeding rising friction slide 2 and the discharging falling friction slide 3.

[0037] In actual power transmission, the motor 42 generates power, which is then transmitted through the reducer 43 and then through the coupling 44 to the steering gear 45 in four positions.

[0038] like Figures 2-5As shown, the vertical transmission assembly 5 includes a vertical transmission frame 51, a main transmission rod 52, a driven transmission rod 53, a first transmission gear 54, a second transmission gear 55, and a bearing 56. The vertical transmission frame 51 is located below the steering gear 45 of each group of the horizontal transmission assembly 4. The main transmission rod 52 and the driven transmission rod 53 are located inside the vertical transmission frame 51, and the main transmission rod 52 is connected to the output end of the steering gear 45 of each group of the horizontal transmission assembly 4. The first transmission gear 54 is located on the main transmission rod 52 and the driven transmission rod 53 and transmits power through meshing. Multiple sets of second transmission gears 55 are provided and installed on the main transmission rod 52 and the driven transmission rod 53. The bearing 56 is located at both ends of the vertical transmission frame 51 and rotatably connects the main transmission rod 52 and the driven transmission rod 53.

[0039] The main drive rod 52 and the second drive gear 55 on the driven drive rod 53 are staggered; the main drive rod 52 and the driven drive rod 53 below the two adjacent sets of steering gears 45 rotate in opposite directions.

[0040] The steering device 45 is located at the outer edge of the intersection of the straight line and the arc of the feeding upward friction slide 2 and the discharging downward friction slide 3. Transmitting power at this location ensures uniform power transmission and avoids problems such as pallet offset caused by unbalanced power transmission. During vertical transmission, the steering device 45 drives the main drive rod 52, which transmits power to the driven drive rod 53 through the first drive gear 54. Then, the power is transmitted to the pallet loaded with goods by the second drive gear 55 on the main drive rod 52 and the driven drive rod 53. Power is transmitted through the meshing rack of the pallet. Moreover, because this utility model has a cross-spiral structure, the main drive rod 52 and the driven drive rod 53 rotate in different directions through the first drive gear 54. Therefore, the second drive gear 55 can also drive the pallets on the feeding upward friction slide 2 and the discharging downward friction slide 3 to slide in different directions.

[0041] Meanwhile, because the reducer 43 transmits power bidirectionally, and each time power is transmitted, it passes through the steering gear 45, the main drive rod 52 and the driven drive rod 53 under the two adjacent sets of steering gears 45 turn in opposite directions, and the pallets on the feed rising friction slide 2 and the discharge falling friction slide 3 driven by them are different.
