Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and more specifically to a tea shaking machine with an automatic push-pull feeding door. Background Technology

[0002] A tea shaking machine, also known as a tea processing machine, is a type of machinery used for processing tea leaves. There are two types of shaking machines: box-type and drum-type. Currently, drum-type shaking machines generally consist of a frame, a drum that can be rotatably mounted on the frame, a drive mechanism that drives the drum, and a hot air blower that supplies hot air to the drum.

[0003] Existing drum-type tea processing machines typically have a tea inlet on the side wall of the drum, covered by a cover plate. To achieve more comprehensive automation, Chinese utility model patent CN217012588U discloses a tea processing machine including a frame, a drum, a door closing mechanism, and a door latch device. The door latch device, used for locking and unlocking the door panel, includes a mounting base, a latch, an elastic element, a rotating element, and a triggering mechanism. The mounting base is located on the outer edge of the drum and has a groove extending towards the inlet. The latch is movably positioned within the groove and limited to the groove in the door opening direction. The elastic element is located between the latch and the mounting base. The rotating element is hinged to the mounting base or the drum to form a lever structure. One end of the lever has a actuating part connected to the latch and used to drive the latch to move along the groove. The other end of the lever has a triggering part. The triggering mechanism includes a triggering element movably positioned relative to the drum, used to drive the triggering part to rotate.

[0004] Although the above-mentioned utility model can lock and unlock the door of the tea processing machine without manual operation, its opening and closing action is complex and cumbersome, the structural cost is high, the opening and closing action range is large, and the space occupied by the closing mechanism and door latch device is high. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a tea shaking machine with an automatic push-pull feeding door.

[0006] The present invention adopts the following technical solution: A tea shaking machine with an automatic push-pull feeding door includes a frame, a drum, a drive mechanism, and a hot air mechanism. The drum is rotatably mounted on the frame and connected to the drive mechanism, which drives the drum to rotate. The hot air mechanism is located at one end of the drum and blows hot air into the drum. The other end of the drum has a discharge port, and the side wall of the drum has a feeding port. The outer side wall of the drum has an electric push-pull door that can slide to block or open the feeding port.

[0007] Furthermore, the electric sliding door is a one-way electric sliding door, including a door panel, a sliding groove, a linear guide rail, and an electric telescopic rod. The sliding groove and the linear guide rail are respectively arranged parallel to each other on the roller sidewalls on the upper and lower sides of the feed inlet. The upper and lower ends of the door panel are slidably connected to the sliding groove and the linear guide rail. The electric telescopic rod is arranged on the roller sidewall and connected to the door panel for pushing the door panel to move horizontally.

[0008] Preferably, the electric sliding door is a two-way electric sliding door, including two one-way electric sliding doors. The two one-way electric sliding doors are symmetrically arranged on both sides of the feed inlet with the vertical center line of the feed inlet as the axis, and the door panels of the two one-way electric sliding doors move in opposite directions.

[0009] Furthermore, it also includes a discharge cover plate and a discharge telescopic mechanism. The discharge telescopic mechanism is mounted on the frame. One side of the discharge cover plate covers the discharge port, and the other side of the discharge cover plate is rotatably pivotally connected to the telescopic end of the discharge telescopic mechanism.

[0010] Furthermore, the center of the other side of the discharge cover is pivotally connected to the telescopic end of the discharge telescopic mechanism via a rotary bearing assembly.

[0011] Preferably, the side of the discharge cover facing the discharge port is provided with a sealing gasket for tightly fitting the discharge port.

[0012] Preferably, the frame further includes a lifting frame and a lifting mechanism. The roller is rotatably mounted on the lifting frame. The end of the lifting frame near the roller outlet is rotatably connected to the frame via a shaft. The lifting mechanism is connected to the end of the lifting frame near the hot air mechanism and is used to drive the lifting frame and the roller to rotate around the shaft.

[0013] Furthermore, the lifting mechanism is a lifting cylinder, and there are two lifting cylinders, which are respectively located on both sides of one end of the lifting frame.

[0014] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. This utility model has an electric sliding door on the side wall of the roller that can slide to block or open the feed inlet. The sliding door is used to realize the automatic opening and closing of the feed inlet. The overall structure is simpler and more compact, the mechanical action is simple, and the electric sliding door mechanism occupies little space.

[0015] 2. The telescopic end of the discharge cover and telescopic mechanism of this utility model adopts a rotatable pivot structure. After the tea leaves are fed into the drum, the discharge cover is pushed by the telescopic mechanism to tightly cover the discharge port, so that the discharge cover can fit tightly against the drum discharge port and rotate with the drum. This can realize the automatic opening and closing of the discharge cover and ensure the airtightness of the drum discharge port.

[0016] 3. The discharge cover of this utility model is provided with a sealing gasket on the side facing the discharge port. The sealing gasket can further improve the airtightness of the discharge port of the roller and provide friction so that the discharge cover can rotate with the roller. Attached Figure Description

[0020] The components in the diagram are labeled as follows: frame 10, roller 20, hot air mechanism 30, lifting frame 11, lifting cylinder 12, feed inlet 21, discharge outlet 22, telescopic cylinder 41, discharge cover plate 42, rotary bearing assembly 43, sealing gasket 44, discharge output belt 50, electric sliding door 60, door panel 61, sliding groove 62, linear guide rail 63, and electric telescopic rod 64. Detailed Implementation

[0021] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0022] Reference Figure 1 A tea shaking machine with an automatic push-pull feeding door includes a frame 10, a drum 20, a drive mechanism, and a hot air mechanism 30. The drum 20 is rotatably mounted on the frame 10 and connected to the drive mechanism, which drives the drum 20 to rotate. The hot air mechanism 30 is located at one end of the drum 20 and blows hot air into the drum 20. The other end of the drum 20 is provided with a discharge port 22, and a discharge conveyor belt 50 is provided below the discharge port 22.

[0023] Reference Figure 1 and Figure 2 The roller 20 has a feed inlet 21 on its side wall, and an electric sliding door 60 on its outer side wall that can slide to block or open the feed inlet 21. The electric sliding door 60 can be a one-way electric sliding door, including a door panel 61, a sliding groove 62, a linear guide rail 63, and an electric telescopic rod 64. The sliding groove 62 and the linear guide rail 63 are respectively arranged parallel to each other on the side walls of the roller 20 on the upper and lower sides of the feed inlet 21. The upper and lower ends of the door panel 61 are slidably connected to the sliding groove 62 and the linear guide rail 63. The electric telescopic rod 64 is set on the side wall of the roller 20 and connected to the door panel 61 for pushing the door panel 61 to slide.

[0024] The electric sliding door 60 of this utility model can also be a bidirectional electric sliding door 60, comprising two unidirectional electric sliding doors 60. The two unidirectional electric sliding doors 60 are symmetrically arranged on both sides of the feed inlet 21 with the vertical center line of the feed inlet 21 as the axis, and the door panels 61 of the two unidirectional electric sliding doors 60 move in opposite directions. Preferably, this embodiment uses a bidirectional electric sliding door 60, which allows the feed inlet 21 to open and close faster, halves the single stroke distance, and shortens the opening and closing time.

[0025] Preferably, this invention provides a position infrared sensor or other position-calibrating sensor around the discharge port on the side wall of the drum 20. This sensor can be calibrated and adjusted with the tea feeding equipment to ensure that the position of the feed inlet 21 is accurate when the drum 20 is feeding tea, preventing tea leaves from falling outside the drum 20. Alternatively, in some embodiments, the position of the discharge port on the side wall of the drum 20 can also be controlled by the drive mechanism of the tea shaking machine. For example, the rotary motor of the drive mechanism uses a PLC control box to control the rotation speed, number of revolutions, and start and stop positions. The PLC control box can also control the stopping position of the drum 20 during feeding, thereby accurately positioning the feed inlet 21.

[0026] Reference Figure 1 and Figure 2 The present invention also includes a discharge cover plate 42 and a discharge telescopic mechanism. The discharge telescopic mechanism is mounted on the frame 10. One side of the discharge cover plate 42 covers the discharge port 22, and the other side of the discharge cover plate 42 is rotatably pivotally connected to the telescopic end of the discharge telescopic mechanism.

[0027] More specifically, the discharge telescopic mechanism is a telescopic cylinder 41, which is fixedly mounted on the frame 10. The telescopic end of the telescopic cylinder 41 is connected to the center of the other side of the discharge cover plate 42 through a rotary bearing assembly 43, so that the discharge cover plate 42 can be pushed by the telescopic cylinder 41 and tightly cover the discharge port 22. At the same time, in order to make the connection between the discharge cover plate 42 and the discharge port 22 tighter, and to make the discharge cover plate 42 rotate with the roller 20 when the roller 20 rotates, a sealing gasket 44 is provided on the side of the discharge cover plate 42 facing the discharge port 22 for tight contact with the discharge port 22. The sealing gasket 44 further improves the airtightness of the discharge port 22 of the roller 20 and provides friction to facilitate the rotation of the discharge cover plate 42 with the roller 20.

[0028] Reference Figures 1 to 3The frame 10, roller 20, drive mechanism, and hot air mechanism 30 of this utility model tea shaking machine are basically the same in structure as existing tea shaking machines, and their tea shaking working principle is also basically the same. Therefore, this utility model is only briefly described here, and its more detailed structural and principle descriptions will not be elaborated further.

[0029] Reference Figure 3 The frame 10 of the tea shaking machine also includes a lifting frame 11 and a lifting mechanism. The roller 20 is rotatably mounted on the lifting frame 11. One end of the lifting frame 11 near the discharge port 22 of the roller 20 is rotatably connected to the frame 10 via a shaft. The lifting mechanism is connected to the end of the lifting frame 11 near the hot air mechanism 30, and is used to drive the lifting frame 11 and the roller 20 to rotate around the shaft. The lifting mechanism consists of two lifting cylinders 12, the output ends of which are hinged to the lifting frame 11 via hinges. The drive mechanism (not shown in the figure) includes a drive motor, a drive wheel connected to the drive motor, a driven wheel located at one end of the roller 20, and a belt connecting the drive wheel and the driven wheel. The drive mechanism is connected to the lifting frame 11 and can be lifted along with the lifting frame 11. The hot air mechanism 30 includes a housing and a hot air fan housed within the housing. The hot air mechanism 30 is a conventional hot air mechanism 30 used in existing tea shaking machines and will not be described in detail here.

[0030] Reference Figures 1 to 3 The bidirectional electric sliding door 60 on the side wall of the tea shaking machine 20 of this utility model opens horizontally, and the tea feed inlet 21 is fed in. Then the bidirectional electric sliding door 60 closes horizontally. Subsequently, the telescopic cylinder 41 operates to push the discharge cover 42 to cover the discharge port 22 of the drum 20, so that the sealing gasket 44 of the discharge cover 42 is tightly attached to the discharge port 22, ensuring the airtightness of the discharge port 22 of the drum 20. Then the tea shaking machine operates normally. Its operation process and principle are basically the same as those of the existing tea shaking machine, and will not be described in detail here.

[0031] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
