Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea kneading machine with adjustable kneading force. Background Technology

[0002] In the process of kneading tea leaves, the existing equipment cannot provide a stable pressure because the volume of the tea leaves decreases after being rolled into rolls. At the same time, the tea leaves will break during the kneading process, and there will be some fragments in the finished product, which will affect the quality of the tea.

[0003] A search revealed that prior art CN116458557A discloses a tea rolling machine, specifically comprising a support frame, a rolling disc, a rolling drum, a drive assembly, and a pressure cap. The rolling disc is connected to the support frame; the rolling drum is positioned above the rolling disc and connected to the support frame via the drive assembly; one end of the pressure cap is rotatably connected to the support frame, and the other end of the pressure cap applies force to the tea leaves placed in the rolling drum; the rolling machine also includes a transmission assembly, which is fixedly mounted on the support frame, and the pressure cap is connected to the transmission assembly via a transmission connection. This device utilizes the pressure cap's self-regulating mechanism to switch the transmission between the pressure cap and the transmission assembly. The transmission between the pressure cap and the transmission assembly can be disconnected when the tea leaves are subjected to a certain pressure, and the pressure cap automatically switches back to the transmission assembly state when the pressure on the tea leaves decreases.

[0004] However, the aforementioned equipment has the following problems during processing: the kneading force is not adjustable; insufficient kneading force makes it difficult for the tea leaves to form a tight, straight, or curved shape, which may result in loose and incomplete tea leaves, affecting the appearance of the tea. Conversely, if the kneading force is too great, the tea leaves may be over-kneaded into powder, which also damages the integrity of the tea. Utility Model Content

[0005] The purpose of this invention is to provide a tea kneading machine with adjustable kneading force, which aims to solve the problem that the kneading force of existing tea kneading machines is not adjustable during processing.

[0006] To achieve the above objectives, this utility model provides a tea kneading machine with adjustable kneading force, including a frame, on which a kneading groove is installed. The lower end of the kneading groove is arc-shaped, and first arc-shaped protrusions are evenly spaced at the inner bottom. It also includes an adjustment mechanism.

[0007] The adjustment mechanism includes a mounting platform, a movable frame, an adjusting screw, an adjusting nut, a spline sleeve, a spline shaft, a rotating shaft, a pressure plate, an indicating device, and a driving device. The mounting platform is integrally formed with the machine frame and is located at the bottom rear side of the machine frame. The movable frame is located at the top of the kneading trough. The adjusting screw is detachably connected to the mounting platform and passes through the movable frame. The adjusting nut is threadedly connected to the adjusting screw and symmetrically abuts against the two end faces of the movable frame. The spline sleeve is detachably connected to the mounting platform and is located on the side of the mounting platform near the movable frame. The spline shaft is fixedly connected to the movable frame and slides with the spline sleeve. The rotating shaft is rotatably mounted on the movable frame. The pressure plate is detachably connected to the rotating shaft and has a second arc-shaped protrusion on its arc-shaped bottom. The indicating device is located on the side of the mounting platform near the movable frame. The driving device is located on the side of the mounting platform near the rotating shaft.

[0008] The indicating device includes a pointer and a ruler. The pointer is detachably connected to the movable frame and is located on the left side of the movable frame. The ruler is detachably connected to the mounting platform and is slidably connected to the pointer, and is located on the top of the mounting platform.

[0009] The drive device includes a main gear and a power assembly. The main gear is fixedly connected to the rotating shaft and is located on the side of the rotating shaft away from the pressure plate. The power assembly is located on the side of the movable frame close to the main gear.

[0010] The power assembly includes a speed-regulating motor and an auxiliary gear. The speed-regulating motor is mounted on the moving frame. The auxiliary gear is mounted on the output shaft of the speed-regulating motor and meshes with the main gear.

[0011] The tea rolling machine with adjustable rolling force also includes a protective mechanism, which includes a side plate and a top plate. The side plate is detachably connected to the movable frame and is symmetrically arranged; the top plate is detachably connected to the side plate and is located on top of the side plate.

[0012] This utility model discloses a tea kneading machine with adjustable kneading force. During processing, a drive device drives a pressure plate to reciprocate, allowing the tea leaves to be pushed by the pressure plate in the kneading groove. Simultaneously, gravity and centrifugal force tightly compress the tea leaves into the gap between the pressure plate and the kneading groove. At the same time, a first arc-shaped protrusion and a second arc-shaped protrusion cooperate to achieve kneading. Furthermore, by adjusting the vertical position of the moving frame with an adjusting nut, the gap between the second arc-shaped protrusion and the first arc-shaped protrusion can be changed. This allows the gap between the pressure plate and the arc-shaped kneading surface of the kneading groove to be adjusted according to the amount of tea leaves and the desired degree of kneading, thereby changing the kneading force. This solves the problem of the non-adjustable kneading force in existing tea kneading machines. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a tea rolling machine with adjustable rolling force. Figure 2 yes Figure 1 Enlarged view of point A in the middle. Figure 3This is a cross-sectional view of the kneading trough 102. This utility model provides a tea kneading machine with adjustable kneading force: it includes a frame 101, a kneading trough 102, and an adjustment mechanism. The adjustment mechanism includes a mounting platform 104, a moving frame 105, an adjusting screw 106, an adjusting nut 107, a spline sleeve 108, a spline shaft 109, a rotating shaft 110, a pressure plate 111, an indicating device, and a driving device. The indicating device includes a pointer 113 and a scale 114. The driving device includes a main gear 115 and a power assembly. The power assembly includes a speed-regulating motor 116 and an auxiliary gear 117. This solution solves the problem of non-adjustable kneading force in existing tea kneading machines. It is understood that the aforementioned solution can achieve kneading force adjustment.

[0022] In this embodiment, a kneading groove 102 is installed on the frame 101. The lower end of the kneading groove 102 is arc-shaped, and first arc-shaped protrusions 103 are evenly spaced at the bottom. The frame 101 can be fixed by bolts. The kneading groove 102 is used for kneading and storing tea leaves.

[0023] The mounting platform 104 is integrally formed with the frame 101 and is located at the bottom rear side of the frame 101. The movable frame 105 is disposed at the top of the kneading trough 102. The adjusting screw 106 is detachably connected to the mounting platform 104 and passes through the movable frame 105. The adjusting nut 107 is threadedly connected to the adjusting screw 106 and symmetrically abuts against the two end faces of the movable frame 105. The spline sleeve 108 is detachably connected to the mounting platform 104 and is located on the mounting platform 102. 04 Near the side of the movable frame 105, the spline shaft 109 is fixedly connected to the movable frame 105 and slidably engaged with the spline sleeve 108. The rotating shaft 110 is rotatably mounted on the movable frame 105. The pressure plate 111 is detachably connected to the rotating shaft 110, and a second arc-shaped protrusion 112 is provided on its arc-shaped bottom. The indicating device is located on the side of the mounting platform 104 near the movable frame 105. The driving device is located on the side of the mounting platform 104 near the rotating shaft 110. The movable frame 105 has a vertical through hole to facilitate the passage of the adjusting screw 106. The adjusting screw 106 is T-shaped, and its bottom disc is fixed with bolts. The adjusting nut 107 is installed on the adjusting screw 106 for adjusting the position of the movable frame 105. The spline sleeve 108 is T-shaped and is fixed to the mounting platform 104 with bolts. The spline shaft 109 is T-shaped, and its top disc is connected to the movable frame 105 with bolts. The mounting shaft end of the rotating shaft 110 is connected to the rotating shaft via a rotating shaft. The pressure plate 111 is mounted on the movable frame 105. Rectangular protrusions are symmetrically arranged on the round shaft on the front side of the rotating shaft 110, and a limiting disc is arranged on the rear side of the rectangular protrusions. This structure prevents the pressure plate 111 from rotating on its own. After the pressure plate 111 is slidably mounted on the rotating shaft 110, it is limited by a disc with a T-shaped structure. The external thread end of the disc is threadedly connected to the rotating shaft 110. The indicating device is used to indicate the position during adjustment. The driving device is used to drive the rotating shaft 110 to rotate, thereby realizing the reciprocating swing of the pressure plate 111.

[0024] Secondly, the pointer 113 is detachably connected to the movable frame 105 and is located on the left side of the movable frame 105; the scale 114 is detachably connected to the mounting platform 104 and slidably connected to the pointer 113, and is located on the top of the mounting platform 104. The scale 114 is L-shaped and has corresponding scale lines. In actual use, a numerical label can be set on one side of the scale line for easy viewing. The pointer 113 is fixed to the movable frame 105 by bolts, and the front indicator part can be aligned and engaged with the scale lines on the scale 114.

[0025] Then, the main gear 115 is fixedly connected to the rotating shaft 110 and is located on the side of the rotating shaft 110 away from the pressure plate 111; the power assembly is disposed on the side of the movable frame 105 close to the main gear 115. The main gear 115 is fixed to the rotating shaft 110 by a flat key and locking bolts, and the power assembly is used to drive the main gear 115 to rotate.

[0026] Finally, the speed-regulating motor 116 is mounted on the movable frame 105; the auxiliary gear 117 is mounted on the output shaft of the speed-regulating motor 116 and meshes with the main gear 115. The speed-regulating motor 116 is fixed to the movable frame 105 by bolts. The equipment of this application is controlled by an external electrical control cabinet. The electrical control cabinet is equipped with control components such as contactors, intermediate relays, timers, and motor speed controllers for equipment control. The forward and reverse rotation of the speed-regulating motor 116 is achieved by the timer periodically activating the forward and reverse rotation control circuit. The auxiliary gear 117 is fixed to the output shaft of the speed-regulating motor 116 by a flat key and locking bolts and meshes with the main gear 115.

[0027] When using this utility model to solve the problem of the non-adjustable kneading force in existing tea kneading machines, the processing is achieved by controlling the forward and reverse rotation of the speed-regulating motor 116 to drive the auxiliary gear 117 to rotate. The rotation of the auxiliary gear 117 drives the main gear 115 to rotate, thereby realizing the rotation of the rotating shaft 110 and driving the pressure plate 111 to swing back and forth. This allows the tea leaves to be pushed by the pressure plate 111 in the kneading groove 102, and at the same time, they are tightly squeezed into the gap between the pressure plate 111 and the kneading groove 102 by gravity and centrifugal force. Simultaneously, the first arc-shaped protrusion 103 and the second arc-shaped protrusion 112 cooperate to achieve kneading. In the first step, the vertical position of the moving frame 105 is adjusted by adjusting the adjusting nut 107 and adjusting the adjusting screw 106. During adjustment, simply loosen the adjusting nut 107 at the corresponding position to change the position. This changes the gap between the second arc-shaped protrusion 112 and the first arc-shaped protrusion 103. The gap between the pressure plate 111 and the arc-shaped kneading surface of the kneading groove 102 can be adjusted according to the amount of tea leaves and the required degree of kneading, thereby changing the kneading force. The adjustment position can be checked by the scale 114 and the pointer 113. This solves the problem that the kneading force of existing tea kneading machines is not adjustable during processing.

[0028] Example 2:

[0029] like Figure 4 As shown, where Figure 4This is a schematic diagram of the overall structure of a tea kneading machine with adjustable kneading force. Based on the first embodiment, this utility model provides a tea kneading machine with adjustable kneading force. The tea kneading machine with adjustable kneading force also includes a protective mechanism, which includes a side plate 201 and a top plate 202.

[0030] The side plate 201 is detachably connected to the movable frame 105 and is symmetrically arranged; the top plate 202 is detachably connected to the side plate 201 and is located on top of the side plate 201. The side plate 201 is fixed with bolts, and the top plate 202 is fixed with bolts and is L-shaped.

[0031] In this embodiment, by setting the side plate 201 and the top plate 202 structure, the transmission areas of the main gear 115 and the auxiliary gear 117 can be isolated, thereby improving the safety of the equipment during processing.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
