Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically a multi-layer lifting and alternating conveying device. Background Technology

[0002] In the current context of rapid development in the food processing industry, the transportation link in the food production process serves as a key link connecting various processing steps. Its efficiency and stability directly affect the overall production rhythm, product quality, and enterprise production cost control. According to announcement number CN211619207U, a multi-layer circulating intelligent transmission system is disclosed. This technology discloses "a system including a picking drive shaft, a picking driven shaft, and a picking drive mechanism connected to the picking drive shaft. A conveyor belt is provided between the picking drive shaft and the picking driven shaft. A picking arm and a picking drive sprocket are installed on the picking drive shaft. A pallet transmission assembly is provided at the end of the picking arm. The pallet transmission assembly includes a pallet and a picking driven sprocket. A linkage shaft is provided between the pallet and the picking driven sprocket. The linkage shaft is rotatably engaged with the picking arm. A picking chain is provided between the picking drive sprocket and the picking driven sprocket. Two picking arms and two picking drive sprockets are symmetrically arranged on the picking drive shaft. This technical solution achieves the purpose of conveying and picking up goods between different height positions, ensuring the timely picking and delivery of goods." Regarding the aforementioned related technologies, the inventors believe that: First, existing conveying devices often use chain lifting to achieve reciprocating lifting and lowering. However, chain lifting has poor stability and is difficult to quickly and smoothly drive the lifting belt to complete the lifting action during the conveying process, which will affect the overall conveying stability of the conveying device. Secondly, the spacing between existing multi-layer conveyor belts is mostly fixed. Due to the differences in food specifications, conveyor belts with fixed spacing cannot meet the conveying needs of different food specifications, which not only results in the inefficient use of space but also limits the applicability of the conveying device. Utility Model Content

[0003] In order to solve the problems of insufficient lifting stability and fixed conveyor belt spacing in existing conveying devices, the purpose of this utility model is to provide a multi-layer lifting and alternating conveying device.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: like Figures 1 to 4 As shown, this utility model provides a multi-layer lifting and alternating conveying device, including a base 1. The base 1 serves as the basic supporting component of the device, providing a stable installation benchmark for the lifting mechanism 2, the spacing adjustment mechanism 3, etc., and ensuring the overall structural stability. The upper surface of the base 1 is provided with the lifting mechanism 2, which is used to drive the first conveyor belt 4 to lift and lower, thereby realizing the alternating conveying of materials at different levels and expanding the spatial dimension of the conveying process.

[0016] See Figure 1 The lifting mechanism 2 of this utility model has a first conveyor belt 4 on one side. The base 1 has a lower conveyor belt 6 and an upper conveyor belt 7 that are used in conjunction with the first conveyor belt 4. The upper surface of the base 1 is fixedly connected with a rectangular array of support rods 5 that are used in conjunction with the lower conveyor belt 6. The lower conveyor belt 6 is fixedly installed on the top of the support rods 5. The support rods 5 are rigidly connected to provide reliable support for the lower conveyor belt 6, ensuring that its position is fixed and the conveying is stable. The upper surface of the base 1 is provided with an adjusting mechanism 3 that is used in conjunction with the upper conveyor belt 7. The adjusting mechanism 3 can flexibly adjust the spacing of the upper conveyor belt 7 to adapt to the conveying of different specifications of food and improve the versatility of the device. It should be noted that the first conveyor belt 4, the upper conveyor belt 7 and the lower conveyor belt 6 are all driven by a drive motor.

[0017] See Figure 2The adjusting mechanism 3 of this utility model includes a guide shell 22, which is fixedly installed on the upper surface of the base 1. A servo motor 21 is fixedly installed on the upper surface of the guide shell 22. The output end of the servo motor 21 passes through the upper surface of the guide shell 22 and is fixedly connected to a lead screw 26. The servo motor 21 serves as a power source, precisely driving the lead screw 26 to rotate, providing a stable and controllable power input for the adjusting action. The bottom end of the lead screw 26 is rotatably connected to the inner cavity of the guide shell 22 and rotatably connected to the inner wall of the guide shell 22, providing a stable rotation point for the lead screw 26. The slider 24 is slidably connected to the inner cavity of the guide shell 22, ensuring the accuracy of the slider 24's movement direction and preventing the slider 24 from rotating with the lead screw 26.

[0018] See Figure 2 The inner cavity of the guide shell 22 of this utility model is symmetrically and fixedly connected with guide rods 25 that cooperate with the slider 24. The slider 24 is slidably sleeved on the outer surface of the guide rod 25. The guide rod 25 guides and limits the slider 24, ensuring the stability and accuracy of the linear movement of the slider 24 and preventing deviation during the adjustment process. A moving block 23 is fixedly connected to one side of the slider 24. The side of the moving block 23 away from the slider 24 passes through the inner wall of the guide shell 22 and is fixedly connected to one side of the first conveyor belt 4. The moving block 23 serves as a connecting component, transmitting the linear movement of the slider 24 to the first conveyor belt 4 to complete the adjustment of the conveyor belt position and adapt to the food conveying requirements.

[0019] See Figure 3 and Figure 4 The adjusting mechanism 3 of this utility model includes a bracket 33, which is fixedly installed on the upper surface of the base 1. A cylinder 32 is fixedly installed on the upper surface of the bracket 33. The cylinder 32 serves as a power element, which drives the connecting plate 35 to rise and fall quickly and stably through telescopic movement, providing efficient power for adjusting the distance. The output end of the cylinder 32 passes through the upper surface of the bracket 33 and is fixedly connected to the connecting plate 35. The cross-sectional shape of the bracket 33 is inverted L-shaped. One side of the connecting plate 35 is slidably connected to the inner wall of the bracket 33, and slides with the inner wall of the bracket 33 to ensure smooth movement.

[0020] See Figure 4 The connecting plate 35 of this utility model has guide blocks 37 symmetrically fixedly connected to both sides. The bracket 33 has guide grooves 36 symmetrically opened on both sides to cooperate with the guide blocks 37. The guide blocks 37 and guide grooves 36 are slidably connected. The guide blocks 37 and guide grooves 36 form a guide pair to accurately limit the lifting trajectory of the connecting plate 35 and prevent skewing or jamming during the adjustment process. One side of the connecting plate 35 is fixedly connected to one side of the upper conveyor belt 7. The connecting plate 35, as a linkage component, transmits the power of the cylinder 32 to the upper conveyor belt 7 to realize the adjustment of the conveyor belt spacing.

[0021] See Figure 2In this invention, a guide ring 34 is symmetrically fixedly installed on one side of the upper conveyor belt 7, and a round rod 31 that works in conjunction with the guide ring 34 is symmetrically fixedly installed on the upper surface of the base 1. The guide ring 34 is slidably sleeved on the outer surface of the round rod 31. The guide ring 34 and the round rod 31 cooperate to provide additional guiding support for the upper conveyor belt 7, enhance its stability and straightness during lifting, and avoid deviation due to unilateral force.

[0022] The working principle of this utility model is as follows: First, the height of the upper conveyor belt 7 is adjusted by the adjusting mechanism 3 according to the specifications of the food being conveyed. Then, the cylinder 32 in the adjusting mechanism 3 is activated. When the cylinder 32 extends and retracts, it drives the connecting plate 35 to slide vertically along the inner wall of the bracket 33. The guide blocks 37, which are symmetrically fixed on both sides of the connecting plate 35, slide along the guide grooves 36 symmetrically opened on both sides of the bracket 33, further restricting the movement direction of the connecting plate 35; Meanwhile, the guide ring 34, which is symmetrically fixed on one side of the upper conveyor belt 7, slides onto the outer surface of the round rod 31, which is symmetrically fixed along the upper surface of the base 1, so as to prevent the upper conveyor belt 7 from shifting and adjust the upper conveyor belt 7 to a suitable distance from the lower conveyor belt 6.

[0023] When it is necessary to adjust the relative height between the first conveyor belt 4 and the upper conveyor belt 7, the servo motor 21 in the pitch adjustment mechanism 3 is started, and the output end of the servo motor 21 drives the lead screw 26 that passes through the upper surface of the guide shell 22 to rotate. When the lead screw 26 rotates, it drives the slider 24 to move vertically along the axis of the guide rod 25. The movable block 23 fixed on one side of the slider 24 moves synchronously with the slider 24. The side of the movable block 23 away from the slider 24 passes through the inner wall of the guide shell 22 and is fixedly connected to the first conveyor belt 4. Finally, it drives the first conveyor belt 4 to complete the height adjustment so that it is flush with the lower conveyor belt 6 or the upper conveyor belt 7 of the target conveying level.

[0024] When materials need to be transferred from the lower conveyor belt 6 to the upper conveyor belt 7, the lifting mechanism 2 drives the first conveyor belt 4 to descend to be flush with the lower conveyor belt 6, and the lower conveyor belt 6 transports the materials to the first conveyor belt 4.

[0025] Subsequently, the lifting mechanism 2 drives the first conveyor belt 4 to rise, making it level with the upper conveyor belt 7. The first conveyor belt 4 transfers the material to the upper conveyor belt 7, completing the conveying from the lower layer to the upper layer.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
