Description

Technical Field

[0001] This utility model relates to the field of tea cake pressing technology, specifically to a rotary tea cake pressing machine. Background Technology

[0002] Tea cakes, also known as compressed tea or compressed tea, are a traditional tea-making method that involves pressing tea leaves into a cake shape. The flavor of tea cakes becomes more mellow and fragrant with age, therefore, the collectible value of tea cakes is far higher than that of loose tea.

[0003] Currently, tea cake pressing machines are key equipment in tea cake production. Their working principle is roughly as follows: pre-treated tea leaves are injected into a forming groove, and then pressure is applied to the tea leaves through a pressing mechanism, causing them to bind tightly and ultimately form a tea cake that matches the shape of the forming groove. This process is crucial to the final quality of the tea cake, directly affecting its compactness, appearance, and subsequent preservation.

[0004] However, existing tea cake pressing machines lack an effective pressure-maintaining structure. Specifically, existing tea cake pressing machines stop pressing immediately after forming the tea cake and begin the unloading process. This practice ignores the fact that although the tea cake has basically taken shape in the initial pressing stage, its internal structure is not yet fully stable. If the pressure is removed immediately at this point, the tea cake is prone to loosening or deformation due to the release of internal stress, affecting the overall quality and appearance of the tea cake.

[0005] Given the problems with existing tea cake pressing machines, it is necessary to develop a rotary cake pressing machine with continuous pressure holding function. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a rotary tea cake machine, which can at least solve the technical problem of how to improve the compactness of tea cakes.

[0007] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rotary pancake machine, comprising: frame; A conveying device is mounted on a frame. At least two placement cylinders are spaced apart on the conveying device. The conveying device is used to convey the placement cylinders. The placement cylinders are provided with forming grooves. The forming grooves are used to place and restrict the pressed shape of the tea leaves. The pressing device is mounted on the frame and positioned opposite the conveying device. The pressing device is used to press the tea leaves in the forming trough into tea cakes that conform to the shape of the forming trough. The pressure holding head and the driving device are arranged in a rotatable manner on the conveying device. The number of pressure holding heads and the placement cylinders are the same and they are arranged in a one-to-one correspondence. The driving device is located on one side of the pressure holding head and is connected to the pressure holding head for transmission. The driving device is used to drive the pressure holding head to rotate towards or away from the corresponding placement cylinder in order to press or release the tea cake in the corresponding forming groove.

[0008] Further, the aforementioned drive device includes: The linkage seat is fixed on the frame and has a first linkage surface and a second linkage surface. The second linkage surface is positioned opposite to the pressing device. The number of elastic elements and pressure holding heads are the same and they are set one-to-one. One end of the elastic element is connected to the conveying device and the other end is connected to the corresponding pressure holding head. The elastic element has a spring force that drives the corresponding pressure holding head to rotate toward the linkage seat so that the corresponding pressure holding head abuts against the first linkage surface or the second linkage surface. When the pressure-holding head abuts against the first linkage surface, the pressure-holding head presses tightly against the forming groove of the corresponding placement cylinder to press the tea cake in the corresponding forming groove; when the pressure-holding head abuts against the second linkage surface, the pressure-holding head releases the tea cake in the corresponding forming groove and completely exposes the corresponding forming groove.

[0009] Further configuration: the aforementioned conveying device is a turntable, with each placement cylinder arranged in annular intervals on the turntable; the first linkage surface is an arc surface, and the axis of the first linkage surface is on the same straight line as the axis of the turntable; the two ends of the second linkage surface are connected to the two ends of the first linkage surface; the second linkage surface is gradually set downward toward the axis of the turntable from the two ends to the middle position.

[0010] Furthermore, the perimeter of the aforementioned first linkage surface is greater than the length of the second linkage surface.

[0011] Further configuration, the aforementioned pressure-holding head includes: The swing arm and the abutting wheel are configured such that one end of the swing arm is rotatably connected to the conveying device and the other end is rotatably connected to the abutting wheel. One end of the elastic element is connected to the conveying device and the other end is connected to the swing arm of the corresponding pressure holding head, so as to drive the abutting wheel of the corresponding pressure holding head to abut against the first linkage surface or the second linkage surface. The pressure arm has one end fixed to the swing arm, and the other end is used to press the tea cake in the forming groove.

[0012] Furthermore, the aforementioned rotary pie machine also includes: The feeding device is mounted on the frame and positioned opposite to the second linkage surface. The feeding device is used to transfer the tea cake in the corresponding forming groove out of the conveying device. A position sensing device is installed on the linkage seat and is positioned opposite to the material feeding device. The position sensing device is used to detect whether the pressure holding head is in contact with the second linkage surface.

[0013] Further, the aforementioned feeding device includes: The clamping mechanism consists of two clamping arms. Each clamping arm has an arc-shaped recess on its opposite side. The output end of the clamping mechanism is connected to the two clamping arms. The clamping mechanism is used to drive the two clamping arms to move towards each other or away from each other to clamp or release the tea cake. The rotating mechanism and the lifting mechanism are connected together. One of the rotating mechanism and the lifting mechanism is located on the frame, and the other is connected to the clamping mechanism. The rotating mechanism and the lifting mechanism are combined to drive the clamping mechanism to move relative to the corresponding forming groove, so as to remove the tea cake in the corresponding forming groove from the conveying device.

[0014] In a further configuration, the aforementioned rotating mechanism includes a telescopic drive and a swing block. Both the telescopic drive and the swing block are rotatably mounted on the frame. The two sides of the rotatable connection of the swing block are respectively provided with a first end and a second end. The first end is rotatably connected to the output end of the telescopic drive, and the second end is fixedly connected to the lifting mechanism or the clamping mechanism.

[0015] (III) Beneficial Effects Compared with the prior art, the rotary pancake maker provided by this utility model has the following beneficial effects: When using the rotary tea cake machine provided by this utility model, firstly, a measured amount of tea leaves are placed into the forming groove of the placement cylinder; then, the conveying device transports the placement cylinder to the pressing device, which quickly presses the tea leaves on the placement cylinder into a tea cake that conforms to the shape of the forming groove; after pressing, the conveying device sends the placement cylinder out of the pressing device area, and at the same time, the driving device drives the pressure-holding head corresponding to the placement cylinder to rotate towards the placement cylinder, so that the pressure-holding head tightly presses the tea cake on the placement cylinder. The pressure-holding operation continues for a period of time, making the internal structure of the tea cake more compact and stable; after a period of time, the driving device drives the pressure-holding head corresponding to the placement cylinder to rotate away from the corresponding placement cylinder and return to its original position, so that the pressure-holding head releases the tea cake on the placement cylinder and completely exposes the forming groove of the placement cylinder, so that the tea cake in the forming groove can be removed later. As can be seen, this utility model can automatically and continuously complete the tea cake pressing process by working together with the conveying device and the pressing device, which greatly improves production efficiency. After the tea leaves are pressed into cakes, the pressure holding head and the driving device work together to continuously apply stable pressure to the tea cakes, effectively avoiding problems such as loosening and deformation that may occur after pressing. This effectively improves the compactness of the tea cakes, making the internal structure of the tea cakes more uniform and dense, and thus comprehensively improving the overall quality of the tea cakes.

Detailed Implementation

[0018] 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.

[0019] This invention provides a rotary tea cake machine to solve the problem of how to improve the compactness of tea cakes.

[0020] See Figure 1 As shown, Figure 1 The image shown is a perspective view of a rotary pancake machine in the embodiment. The rotary pancake machine includes a frame 1, a conveying device 2, a pancake pressing device 3, a pressure holding head 4, and a driving device 5.

[0021] The conveying device 2 is mounted on the frame 1, and at least two placement cylinders 21 are spaced apart on the conveying device 2. The conveying device 2 is used to convey the placement cylinders 21. The placement cylinders 21 have forming grooves 211, which are used to place and restrict the pressed shape of the tea leaves.

[0022] The pressing device 3 is mounted on the frame 1 and positioned opposite the conveying device 2. The pressing device 3 is used to press the tea leaves in the forming groove 211 into tea cakes that conform to the shape of the forming groove 211.

[0023] The pressure holding head 4 is rotatably connected to the conveying device 2. The number of pressure holding heads 4 and the placement cylinder 21 are the same, and they are arranged in a one-to-one correspondence.

[0024] The drive device 5 is installed on one side of the pressure holding head 4 and is connected to the pressure holding head 4 in a transmission manner. The drive device 5 is used to drive the pressure holding head 4 to rotate toward or away from the corresponding placement cylinder 21, so as to press or release the tea cake in the corresponding forming groove 211.

[0025] When using the rotary tea cake machine described above, firstly, a measured amount of tea leaves is placed into the forming groove 211 of the placement cylinder 21. Then, the conveying device 2 transports the placement cylinder 21 to the pressing device 3. The pressing device 3 quickly presses the tea leaves on the placement cylinder 21 into a tea cake that conforms to the shape of the forming groove 211. After pressing, the conveying device 2 sends the placement cylinder 21 out of the pressing device 3 area. At the same time, the driving device 5 drives the pressure-holding head 4 corresponding to the placement cylinder 21 to rotate towards the placement cylinder 21, so that the pressure-holding head 4 tightly presses the tea cake on the placement cylinder 21. The pressure-holding operation continues for a period of time, making the internal structure of the tea cake more compact and stable. After a period of time, the driving device 5 drives the pressure-holding head 4 corresponding to the placement cylinder 21 to rotate away from the corresponding placement cylinder 21, returning to its original position, so that the pressure-holding head 4 releases the tea cake on the placement cylinder 21 and completely exposes the forming groove 211 of the placement cylinder 21, so that the tea cake in the forming groove 211 can be removed subsequently. As can be seen, this utility model, through the coordinated operation of the conveying device 2 and the pressing device 3, can automatically and continuously complete the tea cake pressing process, greatly improving production efficiency. Furthermore, after the tea leaves are pressed into cakes, the coordinated operation of the pressure holding head 4 and the driving device 5 continuously applies stable pressure to the tea cake, effectively avoiding problems such as loosening and deformation that may occur after pressing. This effectively improves the compactness of the tea cake, making its internal structure more uniform and dense, thereby comprehensively improving the overall quality of the tea cake.

[0026] See Figure 1 As shown, in one embodiment of the pressing device 3, the pressing device 3 includes a pressing block 31 and a pressing block driving mechanism 32. The pressing block driving mechanism 32 is mounted on the frame 1 by means of screwing or welding, and the output end of the pressing block driving mechanism 32 is connected to the pressing block 31 by means of screwing or welding. The pressing block driving mechanism 32 is used to drive the pressing block 31 to move towards or away from the corresponding forming groove 211, so as to press or loosen the tea leaves in the corresponding forming groove 211, thereby pressing the tea leaves into a tea cake that conforms to the shape of the forming groove 211.

[0027] The aforementioned pressure block drive mechanism 32 can use existing linear drive mechanisms such as telescopic cylinders or linear modules.

[0028] See Figure 2 As shown, Figure 2This is a schematic diagram of the conveying device, pressure holding head, and driving device in one embodiment. In one implementation of the driving device 5, the driving device 5 includes a linkage seat 51 and elastic elements. The linkage seat 51 is fixed to the frame 1 by screwing or welding, and has a first linkage surface 511 and a second linkage surface 512. The second linkage surface 512 is positioned opposite to the pressing device 3. The number of elastic elements (not shown) and pressure holding heads 4 are the same, and they are arranged in a one-to-one correspondence. One end of the elastic element is connected to the conveying device 2 by hooking or welding, and the other end is connected to the corresponding pressure holding head 4 by hooking or welding. The elastic element has a spring force that drives the corresponding pressure holding head 4 to rotate toward the linkage seat 51, so that the corresponding pressure holding head 4 abuts against the first linkage surface 511 or the second linkage surface 512. When the pressure-holding head 4 abuts against the first linkage surface 511, it presses tightly against the forming groove 211 of the corresponding placement cylinder 21 to compress the tea cake within the groove. When the pressure-holding head 4 abuts against the second linkage surface 512, it releases the tea cake from the groove, fully exposing it. Thus, in use, the initial position of the pressure-holding head 4 abuts against the second linkage surface 512, facilitating the tea feeding and pressing processes. After pressing, the conveying device 2 drives the pressure-holding head 4 to abut against the first linkage surface 511 for tea pressing. After a period of pressing, the conveying device 2 drives the pressure-holding head 4 back to abut against the second linkage surface 512, facilitating the tea unloading process. It can be seen that the driving device 5, through the cooperation of the linkage seat 51 and the elastic element, enables the automatic rotation of the pressure-holding head 4, allowing it to press or release the tea cake at different positions. The structure is simple and reliable, reducing operational difficulty and equipment failure rate.

[0029] The aforementioned elastic element can be a compression spring or a tension spring.

[0030] See Figure 2As shown, in one embodiment of the conveying device 2 and the linkage seat 51, the conveying device 2 is a turntable. Each placement cylinder 21 is distributed in a ring at intervals on the turntable. The first linkage surface 511 is an arc surface, and the axis of the first linkage surface 511 is on the same straight line as the axis of the turntable. The two ends of the second linkage surface 512 are connected to the two ends of the first linkage surface 511. The second linkage surface 512 is gradually oriented downwards towards the axis of the turntable from both ends towards the middle position. Thus, the conveying device 2 is designed as a turntable, so that the rotation of the turntable can drive the pressure-holding head 4 on it to alternately abut against the first linkage surface 511 and the second linkage surface 512. The arc surface design of the first linkage surface 511 allows the pressure-holding head 4 to maintain a tight pressing action on the tea cake in the corresponding forming groove 211 as the turntable rotates, until the pressure-holding head 4 abuts against the second linkage surface 512 as the turntable rotates. The design of the second linkage surface 512 allows the pressure-holding head 4 to first gradually rotate upward toward the axis of the turntable, gradually opening and exposing the corresponding forming groove 211, and then gradually rotate downward away from the axis of the turntable, gradually pressing down on the tea cake in the corresponding forming groove 211.

[0031] In addition to the above-described embodiments, the conveying device 2 can also use existing conveying equipment such as belt conveyors or roller conveyors.

[0032] See Figure 2 As shown, based on the above embodiment, the perimeter of the first linkage surface 511 is greater than the length of the second linkage surface 512. Thus, the greater perimeter of the first linkage surface 511 results in a longer pressing stroke for the pressure-holding head 4 at the first linkage surface 511, ensuring the tea cake is fully compacted; while the shorter stroke at the second linkage surface 512 allows for quick release of the tea cake, improving production efficiency.

[0033] See Figure 2 As shown, in one embodiment of the pressure-holding head 4, the pressure-holding head 4 includes a swing arm 41, an abutment wheel 42, and a pressure arm 43. One end of the swing arm 41 is rotatably connected to the conveying device 2 via a rotating shaft, and the other end is rotatably connected to the abutment wheel 42. One end of an elastic element is connected to the conveying device 2 by means of hooking or welding, and the other end is connected to the swing arm 41 of the corresponding pressure-holding head 4 by means of hooking or welding, so as to drive the abutment wheel 42 of the corresponding pressure-holding head 4 to abut against the first linkage surface 511 or the second linkage surface 512. One end of the pressure arm 43 is fixed to the swing arm 41 by means of integral connection or welding, and the other end is used to press the tea cake in the forming groove 211. Thus, the pressure holding head 4 adopts a structural design of swing arm 41, abutment wheel 42 and pressure arm 43. Through the action of elastic element, it can abut against the linkage surface by rolling abutment wheel 42 during the movement with the conveying device 2, effectively reducing the wear between the pressure holding head 4 and the linkage surface; and the pressure arm 43 can accurately press the tea cake, ensuring the stability and reliability of pressure holding.

[0034] See Figure 1 and Figure 2 As shown, based on any of the above embodiments, the rotary tea cake machine further includes a feeding device 7 and a position sensing device 6. The feeding device 7 is mounted on the frame 1 and is positioned opposite to the second linkage surface 512. The feeding device 7 is used to transfer the tea cake from the corresponding forming groove 211 out of the conveying device 2. The position sensing device 6 is mounted on the linkage seat 51 and is positioned opposite to the feeding device 7. The position sensing device 6 is used to detect whether the pressure holding head 4 is in contact with the second linkage surface 512. Thus, when the tea cake is fed, the conveying device 2 drives the pressure holding head 4 to contact the second linkage surface 512, opening and exposing the corresponding forming groove 211. Then, the feeding device 7 removes the tea cake from the corresponding forming groove 211, realizing automatic feeding of the tea cake and improving the automation level and production efficiency of tea cake production. During this process, the position sensing device 6 detects whether the pressure holding head 4 is in contact with the second linkage surface 512, thereby determining whether the pressure holding head 4 is open and exposes the corresponding forming groove 211. After confirming that the pressure holding head 4 has opened the corresponding forming groove 211, the feeding device 7 then feeds the material. This ensures that the feeding device 7 works at the appropriate time and effectively avoids interference between the pressure holding head 4 and the feeding device 7.

[0035] The aforementioned position sensing device 6 can use an existing position sensing structure that combines a metal sensor sheet and an inductive switch.

[0036] See Figure 1 As shown, in one embodiment of the feeding device 7, the feeding device 7 includes a clamping mechanism 71, two clamping arms 72, a rotating mechanism 73, and a lifting mechanism 74. Each of the two clamping arms 72 has an arc-shaped recess 721 on its opposite sides. The output end of the clamping mechanism 71 is connected to the two clamping arms 72 by screwing or welding. The clamping mechanism 71 drives the two clamping arms 72 to move towards or away from each other to clamp or release the tea cake. The rotating mechanism 73 and the lifting mechanism 74 are connected, with one of the rotating mechanism 73 and the lifting mechanism 74 mounted on the frame 1, and the other being drivenly connected to the clamping mechanism 71. The rotating mechanism 73 and the lifting mechanism 74 work together to drive the clamping mechanism 71 to move relative to the corresponding forming groove 211, thereby removing the tea cake from the conveying device 2. Thus, the feeding device 7 stably clamps and releases the tea cake through the clamping arms 72 of the clamping mechanism 71. The position of the clamping mechanism 71 can be flexibly adjusted through the cooperation of the rotating mechanism 73 and the lifting mechanism 74 to accurately move the tea cake out of the conveying device 2, improving the accuracy and efficiency of feeding. Furthermore, when clamping the tea cake, the two clamping arms 72 move towards each other to form a circular clamping space adapted to the tea cake, effectively preventing the clamping mechanism 71 from damaging the shape of the tea cake.

[0037] See Figure 1As shown, in one embodiment of the feeding device 7, the rotating mechanism 73 includes a telescopic drive member 731 and a swing block 732. Both the telescopic drive member 731 and the swing block 732 are rotatably connected to the frame 1 via a rotating shaft. The swing block 732 has a first end 7321 and a second end 7322 on both sides of its rotatable connection. The first end 7321 is rotatably connected to the output end of the telescopic drive member 731 via a rotating shaft, and the second end 7322 is fixedly connected to the lifting mechanism 74 or the clamping mechanism 71 by screwing or welding. Thus, the telescopic drive member 731's telescopic movement drives the swing block 732 to swing, thereby realizing the rotation of the clamping mechanism 71. The structure is simple, the movement is flexible, and it can meet the rotational requirements for feeding tea cakes.

[0038] The clamping mechanism 71 described above can use an existing clamping cylinder, and the lifting mechanism 74 can use an existing telescopic cylinder or a linear drive mechanism such as a linear module. In addition to the above embodiments, the rotating mechanism 73 can also directly use a rotary motor or other mechanism to achieve the rotation of the clamping mechanism 71. In this embodiment, the rotating mechanism 73 is mounted on the frame 1, and the lifting mechanism 74 is screwed onto the output end of the rotating mechanism 73, with the output end of the lifting mechanism 74 screwed onto the clamping mechanism 71.

[0039] In addition to the above-described embodiments, the feeding device 7 can also directly use a robotic arm or other equipment to feed the tea cake.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
