Description

Technical Field

[0001] The utility model relates to the field of tea conveying equipment, in particular to a tea feeding device. Background Art

[0002] Tea refers to the leaves and buds of the tea tree. It generally refers to the leaves of the evergreen shrub tea tree that can be used to make tea, as well as beverages made from these leaves. Later, it was extended to all herbal teas made from plant flowers, leaves, seeds, and roots, such as "chrysanthemum tea"; "cold tea" made from various medicinal materials, also known as Lei Ya in Chinese literature. Some countries also have teas made from other plant leaves such as fruits and herbs, such as "fruit tea".

[0003] During the production and processing of tea, it is necessary to lift the tea leaves first. When the tea leaves are lifted to a specified height, they can be fed into the feed hopper of other equipment to complete the automatic filling. Currently, a feeding conveyor belt is generally used to transport the tea leaves. However, the feed hoppers of different equipment have different heights, and the feeding conveyor belt generally cannot be adjusted in height. As a result, when the tea leaves are filled into the feed hoppers of other equipment, there is often a large height difference, which causes the tea leaves to scatter everywhere. The feeding effect of the tea leaves into other equipment is not good. At the same time, the thickness of the tea feed is not evenly dispersed. If the tea leaves are too concentrated during the feeding process, it will have a corresponding impact on the subsequent production and processing. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a tea feeding device.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A tea feeding device comprises a feeding conveyor belt body, the feeding conveyor belt body is connected to a support frame, a roller is arranged on the support frame, a locking buckle is arranged on the roller, a mounting frame and an outer cylinder are arranged at the end of the feeding conveyor belt body, an electric cylinder is arranged on the mounting frame, the electric cylinder is connected to the conveyor belt through a connecting plate, the outer cylinder is located below the output end of the feeding conveyor belt body and an inner cylinder is slidably fitted in the outer cylinder, one end of the inner cylinder is connected to the conveyor belt and there is a distance between the inner cylinder and the conveyor belt, a fixing frame and a uniform feeding component are arranged on the conveyor belt, and a distance sensor is arranged on the fixing frame.

[0007] The device can perform uniform feeding process on the feed hoppers of other equipment at different heights. At the same time, the height difference between the feeding end of the device and the feed hoppers of other equipment can be automatically adjusted and maintained within a preset standard range. This can effectively avoid the problem of tea leaves scattering everywhere during the feeding process. At the same time, the thickness of the tea feed is uniform and the feeding effect is good.

[0008] Furthermore, the uniform feeding assembly includes a fixed plate, a servo motor, a rotating shaft and a material shifting rod. The fixed plates are symmetrically arranged at the end of the conveyor belt. A rotating shaft is rotatably connected between the two fixed plates. One end of the rotating shaft is connected to the servo motor fixed on one of the fixed plates. The rotating shaft is provided with a plurality of material shifting rods equidistantly distributed along the width direction of the conveyor belt, and the material shifting rods are spaced apart from the conveyor belt.

[0009] The above scheme can ensure that the thickness of tea leaves is uniform and not easily piled up during the process of feeding tea leaves from the conveyor belt to the feed hopper of other equipment through the uniform feeding component.

[0010] Furthermore, an arc-shaped material baffle is provided on the top side wall of the outer cylinder.

[0011] The above solution can block the top area of ​​the outer cylinder through the arc-shaped baffle plate so that all the tea leaves can fall into the outer cylinder to achieve transfer and finally fall on the conveyor belt.

[0012] Furthermore, the outer cylinder is symmetrically provided with slide grooves, the inner cylinder is provided with sliders that cooperate with the slide grooves and correspond one to one, one end of the outer cylinder is symmetrically provided with limit plates, and one end of the inner cylinder is provided with a moving block that conflicts with the limit plates.

[0014] Furthermore, a push rod and a reinforcement plate are provided on the support frame.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a tea feeding device comprises a feeding conveyor belt body 1, the feeding conveyor belt body 1 is connected to a support frame 2, the support frame 2 is provided with a roller 21, a push rod 23 and a reinforcing plate 22, the roller 21 is provided with a locking buckle, the locking buckle is shown in the figure without a number, a mounting frame 31 and an outer cylinder 32 are provided at the end of the feeding conveyor belt body 1, an electric cylinder 33 is provided on the mounting frame 31, the electric cylinder 33 is connected to the conveyor belt 4 through a connecting plate, the connecting plate is shown in the figure without a number, the outer cylinder 32 is located below the output end of the feeding conveyor belt body 1 and an inner cylinder 321 is slidably fitted in the outer cylinder 32, the outer wall of one end of the inner cylinder 321 is connected to a baffle symmetrically arranged on the conveyor belt 4, the baffle is not numbered in the figure, and the distance between the inner cylinder 321 and the conveyor belt of the conveyor belt 4 is 4-5 cm, a fixing frame 41 and a uniform feeding component are provided on the conveyor belt 4, and a distance sensor 42 is provided on the fixing frame 41.

[0025] Specifically, the uniform feeding component includes a fixed plate 51, a servo motor 52, a rotating shaft and a material shifting rod 53. The fixed plates 51 are symmetrically arranged at the end of the conveyor belt 4. The rotating shaft is rotatably connected between the two fixed plates 51 through a bearing. One end of the rotating shaft is connected to the servo motor 52 fixed on one of the fixed plates 51. The rotating shaft is provided with a plurality of material shifting rods 53 equidistantly distributed along the width direction of the conveyor belt 4. The material shifting rods 53 and the conveyor belt of the conveyor belt 4 are spaced apart. The uniform feeding component can ensure that the thickness of the tea leaves is uniform during the feeding process from the conveyor belt 4 to the feed hopper of other equipment.

[0026] It should be noted that the feeding conveyor belt body 1, the electric cylinder 33, the conveyor belt 4, the distance sensor 42 and the servo motor 52 are all electrically connected to the controller, which is not shown in the figure.

[0027] The workflow of this utility model:

[0028] First, push this device to the side of other equipment that needs to be loaded and make the output end of the conveyor belt 4 just above the feed hopper of other equipment. It should be noted that the loading conveyor belt is initially installed at a high height, and there is no need to continue to increase the height. It is only necessary to lower the loading height according to the height difference of the feed hoppers of different other equipment. Then, stop this device by locking it to prevent the device from moving during the subsequent loading process. Then, the distance sensor 42 starts to detect the distance to the feed hopper of other equipment. If the distance is far, it will feedback a signal to the controller. Then, the controller controls the electric cylinder 33 to work so that the conveyor belt 4 moves down. When the conveyor belt 4 moves down, it will drive the inner cylinder 321 to slide along the outer cylinder 32. When the distance from the end of the conveyor belt 4 to the feed hopper of other equipment is less than the standard range preset in the distance sensor 42 Then the controller controls the electric cylinder 33 to stop working, and then adds tea leaves to the feeding end of the feeding conveyor belt. After the tea leaves are lifted to the end of the feeding conveyor belt, they will fall into the outer cylinder 32 due to weight, and then move along the outer cylinder 32 and the inner cylinder 321 in sequence and finally fall onto the conveyor belt of the conveyor belt 4. At this time, the controller controls the conveyor belt 4 to drive the tea leaves to move to the right, and then the tea leaves will pass through the uniform feeding component. The contact between the material lever 53 and the tea leaves can achieve uniform thickness of the fed tea leaves and is not easy to accumulate. Then the tea leaves can fall evenly into the feeding hopper of other equipment and will not be scattered during the feeding process. When the height of the feeding hopper of other equipment that needs to be filled changes, the above process can be repeated (raising or continuing to lower the height of the conveyor belt) to achieve automatic adjustment of the feeding height, and the feeding effect is good;

[0029] Compared with the existing technology, the device can perform a uniform feeding process on the feed hoppers of other equipment at different heights. At the same time, the height difference between the feeding end of the device and the feed hopper of other equipment can be automatically adjusted and maintained within a pre-set standard range. This can effectively avoid the problem of tea leaves scattering everywhere during the feeding process. At the same time, the thickness of the tea feed is uniform and the feeding effect is good.

[0030] In some embodiments, Figure 1 As shown, an arc-shaped baffle plate 34 is provided on the top side wall of the outer cylinder 32; in this embodiment, the arc-shaped baffle plate 34 can block the top area of ​​the outer cylinder 32 so that all tea leaves can fall into the outer cylinder 32 to achieve transfer and finally fall on the conveyor belt 4;

[0031] In a further optimization of the embodiment, the outer cylinder 32 and the inner cylinder 321 may be circular or square.

[0032] In other embodiments, Figure 3 As shown, a slide groove 301 is symmetrically arranged in the outer cylinder 32, a slider 303 which cooperates with the slide groove 301 and corresponds to the inner cylinder 321 is arranged, a limit plate 302 is symmetrically arranged at one end of the outer cylinder 32, and a moving block 304 which conflicts with the limit plate 302 is arranged at one end of the inner cylinder 321; this embodiment can prevent the inner cylinder 321 from detaching from the outer cylinder 32 during the descent of the conveyor belt 4 by cooperating with the limit plate 302 and the moving block 304.
