Description

Technical Field

[0001] The utility model belongs to the technical field of tea stripping machines, in particular to a tea stripping machine. Background Art

[0002] In the processing of tea strips, a strip-straightening machine is used instead of manual sorting. For example, patent application No. 201310399312.X discloses a shock-absorbing tea strip-straightening machine, which includes a strip-straightening trough, a connecting pendulum and a swing shaft. When working, the machine is driven by electric energy to make reciprocating swings around the hinge point on the swing shaft, so that the tea leaves in the strip-straightening trough will make centrifugal motion and turn over significantly, which has a better strip-straightening effect and can improve the quality of the tea.

[0003] With the technical optimization of the tea stripping machine, in order to prevent tea leaves from falling out of the tea stripping groove, existing solutions, such as patent application No. 202321180186.4, discloses a tea stripping machine, including a bracket, a tea stripping groove, a guide rod and a cover plate, etc. Through the provided positioning block, the cover plate is moved to the upper side of the cover plate and positioned under the drive of the user, so that the cover plate is positioned at the upper opening of the tea stripping groove through the first through hole, thereby reducing the situation of tea leaves falling inside the tea stripping groove and making the process of tea stripping more convenient.

[0004] Although the above-mentioned method of using a cover plate can solve the problem of tea leaves falling out of the strip sorting groove, it is inconvenient to operate. It is mainly reflected in that when the cover plate is in use, it is necessary to manually move the cover plate to place it, and then pull the four positioning blocks one by one and rotate it. When the cover plate needs to be taken out of the tea leaves after use, similarly, it is necessary to first operate the four positioning blocks to release the restrictions on the cover plate, and then remove the cover plate. The use process of the cover plate is relatively cumbersome, and the steps of operating the four positioning blocks one by one are relatively inconvenient. Moreover, the manual moving process of taking and placing the cover plate increases the physical labor of the staff. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a tea strip sorting machine, which drives the installation plate to move by an electric push rod. The connecting mechanism can passively extend and retract as the cover plate moves, so as to keep the cover plate and the strip sorting groove always in contact with the position limit, thereby simplifying the manual operation process and reducing the physical labor of the staff.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tea stripping machine comprises a bracket, a stripping groove is arranged inside the bracket, a cover plate is arranged at the opening at the top of the stripping groove, guide rods are arranged at the four corners at the top of the stripping groove, a first through hole is opened at the four corners of the cover plate, the guide rod is located inside the first through hole, an electric push rod is fixedly connected to the right side of the bracket, a mounting plate is fixedly connected to the telescopic end of the electric push rod, a connecting mechanism is arranged between the mounting plate and the cover plate, there are two connecting mechanisms and they are symmetrically distributed on the left and right sides of the cover plate, the connecting mechanism comprises a sleeve, a movable rod and a spring, the bottom of the mounting plate is hinged with a sleeve, the top of the cover plate is hinged with a movable rod, the upper part of the movable rod is located on the inner side of the sleeve and is slidably connected to the sleeve, the top of the movable rod is fixedly connected with a spring, and the top of the spring is fixedly connected to the top of the inner cavity of the sleeve.

[0008] Furthermore, a screw sleeve is fixedly connected to the left side of the bracket, and the screw sleeve is threadedly connected to a screw rod.

[0009] Furthermore, a second through hole is formed on the outer side of the sleeve.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The electric push rod drives the mounting plate to move, so that the connecting mechanism can carry the cover plate to move up and down, so that when the cover plate is downward, it covers the opening of the strip sorting slot to prevent the tea leaves in the strip sorting slot from falling out during sorting. When the cover plate is upward away from the strip sorting slot, the tea leaves in the strip sorting slot can be taken out. Compared with the method of manually moving the cover plate and operating the four positioning blocks to limit the cover plate, the manual operation process is simplified and the physical labor of the staff is reduced.

[0012] 2. Through the sleeve and the sliding movable rod in the connecting mechanism, which are respectively hinged with the mounting plate and the cover plate, the cover plate is abutted against the strip sorting groove with the spring thrust, so that when the cover plate is working as the strip sorting groove is sorting the strips, the connecting mechanism can passively extend and retract as the cover plate moves, so as to keep the position limit that the cover plate and the strip sorting groove are always abutted.

[0013] 3. Through the threaded sleeve and the screw, it is convenient to adjust the height of the top of the screw by screwing, so as to limit the downward height of the mounting plate and avoid the mounting plate being too downward, causing the spring to be compressed beyond the limit, resulting in the spring yielding after deformation, thereby protecting the ultimate compression degree of the spring and improving the service life of the spring. Through the second through hole, it is convenient to add lubricating oil to the sleeve to increase the smoothness of the sliding of the movable rod. In addition, when the movable rod moves, it is convenient to balance the air pressure in the sleeve to avoid positive or negative pressure in the sleeve, which affects the smooth sliding of the movable rod.

Example

[0018] See attached Figure 1 As shown, a tea strip sorting machine comprises a bracket 1, a strip sorting groove 2 is arranged inside the bracket 1, a cover plate 3 is arranged at the opening at the top of the strip sorting groove 2, guide rods 4 are arranged at the four corners at the top of the strip sorting groove 2, first through holes 5 are opened at the four corners of the cover plate 3, the guide rods 4 are located inside the first through holes 5, an electric push rod 6 is fixedly connected to the right side of the bracket 1, a mounting plate 7 is fixedly connected to the telescopic end of the electric push rod 6, a connecting mechanism is arranged between the mounting plate 7 and the cover plate 3, and the number of the connecting mechanisms is two and they are opposite It is distributed on the left and right sides of the cover 3, and the connecting mechanism includes a sleeve 8, a movable rod 9 and a spring 10. The bottom of the mounting plate 7 is hinged with the sleeve 8, and the top of the cover 3 is hinged with the movable rod 9. The upper part of the movable rod 9 is located on the inner side of the sleeve 8 and is slidably connected with the sleeve 8. The top of the movable rod 9 is fixedly connected with the spring 10, and the top of the spring 10 is fixedly connected with the top of the inner cavity of the sleeve 8. The left side of the bracket 1 is fixedly connected with a screw sleeve 11, and the screw sleeve 11 is threadedly connected with a screw 12. A second through hole 13 is opened on the outside of the sleeve 8.

[0019] Working principle: It should be noted that, in the present invention, only the operation method of the cover plate 3 in the disclosed technology is improved, and the way in which the tea strip sorting groove 2 swings to sort the tea strips is not changed, and its original effect is retained. The motor is still used to drive the tea strip sorting groove 2 to swing back and forth. The specific swinging principle is the existing disclosed technology, and the details can be obtained by referring to the patent mentioned in the background technology. The standard for selecting the spring 10 is that when the top of the movable rod 9 is located at the bottom of the inner cavity of the sleeve 8, the spring 10 is still in a compressed state, and the required adjustment height of the screw rod 12 is determined according to the spring 10. The standard is that when the spring 10 is compressed to the shortest limit distance, The height of the mounting plate 7 is set, and the top of the screw 12 only needs to be slightly higher than this height. The adjustment method is to rotate the screw 12. Before using the strip sorting groove 2, first put the tea leaves into the strip sorting groove 2, and the strip sorting groove 2 is in a vertical state in the figure. At this time, the first through hole 5 on the cover plate 3 corresponds to the guide rod 4 on the strip sorting groove 2. In this way, when using the cover plate 3, the telescopic end of the electric push rod 6 contracts, driving the mounting plate 7 downward, and the two connecting mechanisms drive the cover plate 3 to move downward synchronously with the mounting plate 7. When the cover plate 3 contacts the top of the strip sorting groove 2, the guide rod 4 is inserted into the first through hole 5, and then the mounting plate 7 continues to move downward, and the sleeve 8 moves downward synchronously with the mounting plate 7. 9 As the cover plate 3 cannot continue to move downward, the sleeve 8 and the movable rod 9 approach each other during the downward process, and the spring 10 is further squeezed by the two. The tendency of the spring 10 to return causes the movable rod 9 to have an area for pushing downward, so that the cover plate 3 abuts against the strip sorting groove 2 until the mounting plate 7 contacts the screw 12. At this time, the cover plate 3 is limited and fixed on the strip sorting groove 2 by the elasticity of the spring 10. When the strip sorting groove 2 sorts the tea strips, the strip sorting groove 2 will swing left and right. In this process, the strip sorting groove 2 drives the guide rod 4 to move, and the guide rod 4 drives the cover plate 3 to swing synchronously. When the cover plate 3 moves to the left and right, it drives the movable rod 9 and the sleeve 8 to tilt accordingly. , and pull the movable rod 9 to repeatedly extend and slide in the sleeve 8, while the spring 10 is always in a compressed state, so that the cover plate 3 and the strip sorting groove 2 are always kept in abutment state, ensuring that the strip sorting groove 2 is swinging, and the tea leaves can be blocked by the cover plate 3 to avoid falling out of the strip sorting groove 2 during swinging. After the tea leaves are sorted, when the cover plate 3 needs to be removed, the electric push rod 6 is started again to drive the mounting plate 7 to reset upward. When the top of the movable rod 9 is located at the bottom of the sleeve 8, at this time, the cover plate 3 will move upward away from the strip sorting groove 2 with the mounting plate 7 until the cover plate 3 is reset. Therefore, the entire use process of the cover plate 3 can be completed by the staff only needing to start the electric push rod 6 twice.
