Description

Technical Field

[0001] The utility model relates to the technical field of tea weighing, in particular to automatic tea weighing equipment. Background Art

[0002] Tea processing, also known as "tea making", is the process of making various semi-finished tea or finished tea through various processing procedures of fresh tea leaves. According to different processing procedures, it can be divided into primary processing (primary processing), refining (fine processing), reprocessing and deep processing. Different processing techniques will form different types of tea. The quality of each type of tea depends on the coordination of the processing procedures; high-quality fresh leaf raw materials can only produce high-quality tea under excellent processing conditions.

[0003] After tea processing is completed, the tea needs to be weighed for packaging. Currently, most small and medium-sized tea factories use manual grabbing of tea leaves for weighing, and manually adjusting the weight of the tea leaves during the weighing process, which is labor-intensive and inefficient.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The utility model provides an automatic weighing device for tea. First, a set weight value is set through the control panel of the weighing device. When the feeding conveyor of the previous process discharges the material to the set value into the symmetrical weighing bucket, the feeding conveyor is controlled to stop through the external control device, and the forward and reverse motors are started to rotate forward to drive the wire-receiving roller to reel in the wire, so that the movable baffle is rotated along the intersection and compresses the torsion spring until the right side of the baffle abuts against the support rod.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 4 , the embodiment proposed in the present application is: an automatic weighing device for tea, comprising a weighing platform 1, a feeding conveyor belt 2 is horizontally arranged above the weighing platform 1, a weighing device is fixedly arranged on the upper side of the weighing platform 1, a control panel 31 is arranged on the front side of the weighing device 3, the weighing device 3 is electrically connected to an external control device, a weighing bucket 4 is arranged on the upper side of the weighing device 3, a feeding port on the upper side of the weighing bucket 4 corresponds to the unloading position of the feeding conveyor belt 2, a movable baffle 5 is movably arranged on the right side of the weighing bucket 4, and an inclined plate 41 is arranged in the weighing bucket 4 corresponding to the movable baffle 5, which is inclined downward from left to right, a unloading drive component 6 is also arranged on the upper side of the weighing platform 1, which is located on the right side of the weighing device 3, the unloading drive component 6 is drivingly connected to the movable baffle 5, and the unloading drive component 6 is electrically connected to an external control device, and a material receiving area 7 is also arranged on the upper side of the weighing platform 1, which is located on the right side of the unloading drive component 6, and the material receiving area 7 can abut against the movable baffle 5;

[0027] The weighing weight is set through the control panel 31 of the weighing device 3. When the feeding conveyor belt 2 feeds the weighing bucket 4 to the set weight, the feeding conveyor belt 2 is stopped by the external driving device, and the unloading driving component 6 is operated to drive the movable baffle 5 to open for unloading. The overall design is simple and is more accurate and quick than manual weighing, thereby improving the weighing efficiency. At the same time, the external control equipment and electrical connection method here belong to the prior art and will not be described in detail here.

[0028] In another embodiment, see Figures 1 to 4 An opening is provided on the right side of the weighing bucket 4 corresponding to the movable baffle 5, the lower side of the movable baffle 5 is hinged to the lower side of the opening, and baffle plates 51 are fixedly provided on the front and rear walls of the opening corresponding to the front and rear sides of the movable baffle 5, respectively, and the two baffle plates 51 are arranged outside the opening, and a clearance groove 42 is provided on the front and rear walls of the weighing bucket 4 corresponding to the hinge, so that the movable baffle 5 can smoothly rotate along the hinge, and a torsion spring 52 is provided at the hinge between the movable baffle 5 and the lower side of the opening;

[0029] When weighing, the movable baffle 5 is driven by the torsion spring 52 to be close to the right side of the weighing bucket 4, so that the tea leaves are collected. When unloading is required, the movable baffle 5 is driven by the unloading drive assembly 6 to rotate to be consistent with the inclined plate in the weighing bucket 4. At this time, the two baffle plates 51 are limited when the tea leaves are unloaded to ensure that they are accurately placed in the collecting area 7.

[0030] In another embodiment, see Figures 1 to 4 The material unloading drive assembly 6 includes a wire-taking rod 61, and a mounting bracket 11 is fixedly provided on the lower side of the weighing platform 1 corresponding to the wire-taking rod 61. The wire-taking rod 61 is mounted on the mounting bracket 11 and is rotatably connected thereto. A steel wire 62 is wound around the wire-taking rod 61, and the steel wire 62 passes through the weighing platform 1 upward and is fixedly connected to the middle part of the right side of the movable baffle 5. The steel wire 62 is slidably connected to the weighing platform 1. A support rod 67 is vertically provided on the upper side of the weighing platform 1 corresponding to the steel wire. The steel wire passes through the support rod 67 and is slidably connected thereto. The top of the support rod 67 can abut against the right side of the movable baffle 5, and a rubber pad 53 is provided at the abutment position of the right side of the movable baffle 5 corresponding to the support rod 67.

[0031] In this embodiment, the material unloading drive assembly 6 also includes a forward and reverse motor 63, which is electrically connected to an external driving device. The forward and reverse motor 63 is fixedly arranged on the lower side of the weighing platform 1 and is located on the left side of the wire take-up roller 61.

[0032] When weighing is completed and the material is unloaded, the forward and reverse motor 63 is controlled by the external control device to rotate forward, thereby driving the wire-reeling roller 61 to reel in the wire, so that the movable baffle 5 rotates along the intersection and compresses the torsion spring 52, until the right side of the movable baffle 5 abuts against the support rod 67. At this time, the inclination of the movable baffle 5 is consistent with the inclined plate 41 in the weighing bucket 4. Due to gravity, the tea leaves slide from the weighing bucket 4 to the receiving area 7 for packaging. The weighing bucket 4 loses weight, thereby triggering the external control device to control the forward and reverse motor 63 to reverse, so that the wire-reeling roller 61 releases the wire, and the movable baffle 5 rotates and resets under the action of the torsion spring 52 to carry out the next round of weighing.
