Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea rolling technology, and in particular to a tea rolling machine. Background Technology
[0002] Tea rolling is the initial shaping process of tea. Through specific mechanical devices or manual operation, pressure is applied to the tea leaves that have undergone pre-treatment such as withering, causing them to rotate, squeeze, and rub, which breaks the tea cells, allows the tea juice to seep out, and at the same time shapes the tea leaves into a specific shape.
[0003] Chinese utility model patent CN218483692U discloses a tea rolling machine. During discharge, a control valve is opened, allowing tea leaves to enter the discharge cylinder and fall into the discharge chute. During cleaning, an electric telescopic rod drives the rolling ring downwards, scraping off residue from the opening of the rolling plate. A screw drives a pressure plate downwards, pressing the scraper against the rolling plate. Simultaneously, water is supplied to allow the residue to be discharged into the discharge cylinder. Residue on the scraper can be cleaned by lifting the pressure plate. This tea rolling machine has two main problems: first, the scraper can only clean residue below the rolling ring on the rolling plate, failing to clean residue from other corners of the rolling plate; second, the cleaning process involves rinsing the surface of the rolling plate with water to remove residue, which accelerates rust and corrosion of the metal parts, shortening the machine's lifespan. Utility Model Content
[0004] The purpose of this invention is to provide a tea kneading machine that effectively cleans residues and ensures stable operation.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A tea kneading machine includes a support leg, a crank connecting rod, a kneading disc, and a kneading cylinder. Three support legs are arranged in a circular array. The top of the support leg is rotatably connected to the lower end of the crank connecting rod. The kneading cylinder is located above the support leg. The outer wall of the kneading cylinder is fixedly connected to the upper end of the crank connecting rod. The lower surface of the crank connecting rod is provided with a groove. A telescopic rod is fixedly connected to the support leg near the center. A rubber air bladder is sleeved on the outer wall of the telescopic rod. The kneading disc is located below the kneading cylinder and is fixedly connected to the top of the telescopic rod. A force-bearing rod is slidably arranged at the bottom of the kneading disc. A locking plate is rotatably connected to the bottom of the force-bearing rod. An L-shaped bracket is fixedly connected below the kneading disc. An insert plate is fixedly connected to the outer wall of the support leg. The insert plate is located below the L-shaped bracket. When the locking plate is placed on the L-shaped bracket, the top of the force-bearing rod fits into the groove. When the locking plate is placed on the insert plate, the force-bearing rod moves away from the groove.
[0006] By adopting the above technical solution, when the locking plate is located on the insert plate, the kneading disc only participates in the circumferential kneading motion of the kneading cylinder, and the rubber airbag plays a role in buffering and shock absorption, reducing the vibration and noise of the kneading machine during operation; when the locking plate is located on the L-shaped bracket, the force rod abuts against the groove on the lower surface of the crank connecting rod, and the crank connecting rod applies a downward force to the kneading disc, the rubber airbag is compressed, causing the kneading disc to move downward with the telescopic rod. After the crank connecting rod leaves the force rod, the kneading disc rises under the restoring force of the rubber airbag, and the kneading disc moves up and down reciprocally, making it easier for the residue adhering to the kneading disc to detach, thereby achieving efficient cleaning of the residue.
[0007] A further feature of this invention is that the locking plate has a hole, and the insert plate and the L-shaped bracket are respectively fixedly connected with protrusion one and protrusion two, and the hole is adapted to protrusion one and protrusion two.
[0008] By adopting the above technical solution, when the hole of the locking plate is embedded in protrusion one or protrusion two, the locking plate will not easily move, thus ensuring the stability of the equipment's state and the reliability of its operation.
[0009] A further feature of this invention is that an arc-shaped buffer pad is provided at the top of the force-bearing rod.
[0010] By adopting the above technical solution, when the crank connecting rod presses down on the force-bearing rod, the arc-shaped buffer pad can play a buffering role, reducing the rigid collision between the crank connecting rod and the force-bearing rod, and protecting the force-bearing rod and the crank connecting rod.
[0011] A further feature of this invention is that a pressure plate is provided above the kneading cylinder.
[0012] By adopting the above technical solution, the pressure plate can apply pressure to the tea leaves in the kneading cylinder, so that the tea leaves are subjected to more uniform and appropriate pressure during the kneading process, thereby improving the kneading quality.
[0013] A further feature of this invention is that a support rod is fixedly connected above the crank connecting rod, and a connecting rod is slidably connected to the outer wall of the support rod, with the connecting rod threadedly connected to the pressure plate.
[0014] By adopting the above technical solution, adjusting the position of the connecting rod on the support rod, and adjusting the height of the pressure plate through the threaded connection, the pressure applied by the pressure plate to the tea can be flexibly adjusted to suit different types of tea.
[0015] A further feature of this invention is that a discharge valve is provided at the bottom of the kneading disc.
[0016] By adopting the above technical solution, the discharge valve at the bottom of the kneading disc facilitates the discharge of tea leaves after kneading, preventing tea leaves from remaining in the kneading disc and making it easier to clean the equipment.
[0017] A further feature of this invention is that the inner bottom wall of the kneading disc is provided with multiple sets of kneading ribs.
[0018] By adopting the above technical solution, the kneading ribs on the bottom wall of the kneading disc can knead and turn the tea leaves when the kneading disc rotates, so that the tea leaves can fully contact and rub against the kneading disc, kneading cylinder and pressing plate, thereby improving the curliness and quality of the tea leaves.
[0019] A further feature of this invention is that a drive motor is fixedly connected inside any one of the support legs, the output axis of the drive motor extends upward and is fixedly connected to the lower end of the crank connecting rod.
[0020] By adopting the above technical solution, the drive motor rotates, driving the crank connecting rod to rotate, thus ensuring the rotational stability and reliability of the crank connecting rod.
[0021] The beneficial effects of this utility model are:
[0022] 1. This utility model features a force-bearing rod penetrating the edge of the kneading disc, and a groove on the lower surface of the crank connecting rod. When the locking plate is positioned on the L-shaped bracket, the force-bearing rod abuts against the groove on the lower surface of the crank connecting rod. During the rotation of the crank connecting rod, a downward force is applied to the kneading disc, causing it to move downwards with the telescopic rod. When the crank connecting rod disengages from the force-bearing rod, the kneading disc rises under the restoring force of the rubber airbag, thus achieving the reciprocating motion of the kneading disc. Compared to the traditional method of cleaning solely with a scraper, this utility model, through the reciprocating motion of the kneading disc, makes it easier for residues adhering to the kneading disc to detach, achieving efficient residue cleaning without the need for rinsing, thus avoiding the problem of rust and corrosion of the equipment's metal parts caused by rinsing.
[0023] 2. This utility model is equipped with an insert plate and an L-shaped bracket, which allows for convenient switching of the working state of the kneading disc. When the locking plate is located on the insert plate, the kneading disc only participates in the circumferential kneading motion of the kneading cylinder. At this time, the rubber airbag plays a role in buffering and shock absorption, effectively reducing the vibration and noise of the kneading machine during operation. When the locking plate is rotated to the L-shaped bracket, the kneading disc can shake up and down to clean up residues, meeting the needs of different stages of use.
[0024] 3. The arc-shaped buffer pad provided at the top of the force-bearing rod of this utility model can effectively buffer the rigid collision between the two when the crank connecting rod presses down on the force-bearing rod, reduce the wear between the components, protect the force-bearing rod and the crank connecting rod, and extend their service life.
[0025] 4. One end of the connecting rod of this utility model is slidably connected to the support rod, and the other end is threadedly connected to the pressure plate. By adjusting the position of the connecting rod on the support rod and rotating the pressure plate to adjust its height, the pressure applied by the pressure plate to the tea can be flexibly adjusted to suit different types of tea.

[0032] Example: A tea rolling machine, such as Figures 1-3As shown, the device includes a support leg 1, a crank connecting rod 2, a kneading disc 3, and a kneading cylinder 4. Three support legs 1 are arranged in a circular array. The top of each support leg 1 is rotatably connected to the lower end of the crank connecting rod 2. The kneading cylinder 4 is located above the support legs 1, and its outer wall is fixedly connected to the upper end of the crank connecting rod 2. The lower surface of the crank connecting rod 2 has a groove 21. A telescopic rod 5 is fixedly connected to the support leg 1 near the center. A rubber air bladder 51 is fitted onto the outer wall of the telescopic rod 5. The kneading disc 3 is located below the kneading cylinder 4 and is fixedly connected to the top of the telescopic rod 5. A force-bearing rod 6 is slidably arranged at the bottom of the kneading disc 3, and a locking plate 62 is rotatably connected to the bottom of the force-bearing rod 6. An L-shaped bracket 31 is fixedly connected below the kneading disc 3. An insert plate is fixedly connected to the outer wall of the support leg 1. 11. The insert plate 11 is located below the L-shaped bracket 31. When the locking plate 62 is placed on the L-shaped bracket 31, the top of the force rod 6 fits into the groove 21. When the locking plate 62 is placed on the insert plate 11, the force rod 6 is away from the groove 21. The locking plate 62 is provided with holes. The insert plate 11 and the L-shaped bracket 31 are respectively fixedly connected with protrusion 12 and protrusion 2 32. The holes are adapted to protrusion 12 and protrusion 2 32. The top of the force rod 6 is provided with an arc-shaped buffer pad 61. The bottom of the kneading disc 3 is provided with a discharge valve 34. The inner bottom wall of the kneading disc 3 is provided with multiple sets of kneading ribs 33. The drive motor 8 is fixedly connected inside any one of the support legs 1. The output axis of the drive motor 8 extends upward and is fixedly connected to the lower end of the crank connecting rod 2.
[0033] Its working principle is as follows: First, the tea leaves are loaded into the kneading cylinder 4, the pressure plate 72 is rotated and its height is adjusted so that the pressure plate 72 is in full contact with the tea leaves and applies pressure to the tea leaves; second, the locking plate 62 is rotated to the insertion plate 11 so that the hole on the locking plate 62 is inserted into the protrusion 12 on the insertion plate 11. At this time, the crank connecting rod 2 is not in contact with the force rod 6. The drive motor 8 is started, and the output shaft of the drive motor 8 drives the crank connecting rod 2 to rotate. Under the drive of the crank connecting rod 2, the kneading cylinder 4 makes a circular motion on the kneading disc 3 to knead the tea leaves. The tea leaves are subjected to friction and extrusion between the kneading ribs 33 and the kneading cylinder 4, and gradually form a specific shape; after kneading, it is necessary to... When cleaning the tea leaves on the kneading disc 3, open the discharge valve 34 and simultaneously rotate the locking plate 62 onto the L-shaped bracket 31, so that the hole on the locking plate 62 is inserted into the protrusion 32 on the L-shaped bracket 31. At this time, the force rod 6 abuts against the groove 21 on the lower surface of the crank connecting rod 2. Then start the drive motor 8. As the crank connecting rod 2 rotates, when the groove 21 rotates to the position of the force rod 6, the crank connecting rod 2 applies a downward force to the force rod 6, thereby driving the kneading disc 3 to move downward with the telescopic rod 5, and the rubber air bag 51 is compressed. When the crank connecting rod 2 leaves the force rod 6, the rubber air bag 51 pushes the kneading disc 3 upward under its own restoring force. The kneading disc 3 moves up and down reciprocally, making it easier for the residue adhering to the kneading disc 3 to detach, thereby achieving efficient cleaning of the residue.
[0034] Specifically, a pressure plate 72 is provided above the kneading cylinder 4, and a support rod 7 is fixedly connected above the crank connecting rod 2. A connecting rod 71 is slidably connected to the outer wall of the support rod 7. The connecting rod 71 is threadedly connected to the pressure plate 72. The position of the connecting rod 71 on the support rod 7 and the height of the pressure plate 72 are adjusted by adjusting the threaded connection, thereby flexibly adjusting the pressure applied by the pressure plate 72 to the tea leaves to adapt to different types of tea.
