Description

Technical Field

[0001] The utility model relates to the technical field of grain counting machines, in particular to a static weighing and sorting scale suitable for strip-shaped materials. Background Art

[0002] Coffee, milk tea, cereal and other foods are often packaged in strips, which makes it easier to measure the packaging during production and packaging. Users can also easily pour out the powder when brewing. In order to ensure that each strip of material has the same flavor after brewing, such strip materials need to be weighed and inspected during production and packaging to ensure that the weight of each independently packaged strip material meets the standard. In addition, many pharmaceutical powders are also packaged in strips. In order to ensure accurate dosage, tablet powders packaged in strips have higher requirements for the accuracy of packaging weight.

[0003] However, there are many problems with the current weighing schemes for such strip materials. For example, weighing inspections are mostly batch weighing, which makes it difficult to detect independent packages with large weight deviations. After weighing inspections, they often rely on manual sorting and boxing, which is inefficient and has high labor costs. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] See also Figures 1 to 3 The static weighing and sorting scale suitable for strip materials may include the following contents.

[0028] Several weighing components 1 are arranged side by side, and the input end of the weighing component 1 is a guide trough 2;

[0029] The guide trough 2 is used to convey the strip-shaped material to the weighing table of the weighing assembly 1 through the conveyor belt 3;

[0030] A discharge slide rail 4 is provided at the output end of the weighing assembly 1, and the discharge slide rail 4 is assembled on the reject cylinder 41;

[0031] A reject conveyor belt 5 is provided below the output end of the weighing assembly 1;

[0032] The weighing assembly 1 and the rejecting cylinder 41 are electrically connected to the central control assembly 6 .

[0033] The input end of the guide trough can be connected to the discharge port of the packaging machine and other equipment to obtain stable and uniform feeding. The conveyor belts on both sides of the guide trough are higher than the bottom, which can guide the limited strip-shaped materials to be transported axially to avoid jamming.

[0034] After the strip material is conveyed to the top of the weighing platform of the weighing component, the conveyor belt stops running to allow the weighing component to perform static weighing, and after the static weighing is completed, the strip material is output from the output end of the weighing component.

[0035] At this time, if the weighing component measures that the weight of the strip material on it is within the qualified weight range, the strip material will fall onto the discharge slide rail after being output and will be discharged as a qualified product.

[0036] If the weighing component measures that the weight of the strip material on it is lower or higher than the qualified weight range, the central control component controls the rejection cylinder corresponding to the weighing component where the strip material is located to open, thereby guiding the material trough to rise. After outputting the weighing component, the strip material will fall onto the rejection conveyor belt and be rejected as out-of-limit material, thereby achieving accurate and efficient sorting of qualified products and out-of-limit materials.

[0037] In this embodiment, the width of the guide trough 2 is adjustable.

[0038] Here, since the widths of different strip-shaped materials are different, and there may also be width differences between different batches of the same type of strip-shaped materials, in order to ensure that the strip-shaped material and the guide trough remain axially consistent, the widths of both sides of the guide trough are adjustable, and after adjusting to the appropriate width, screws are used to tighten and lock it to well adapt to various types of strip-shaped materials.

[0039] In this embodiment, the driving wheel 23 of the conveyor belt 3 is arranged at the output end of the weighing assembly 1 , and the driven wheel 33 of the conveyor belt 3 is arranged at the input end of the guide trough 2 .

[0040] In this embodiment, a baffle 31 is disposed on the surface of the conveyor belt 3 to push the strip-shaped material on the surface of the conveyor belt 3 to move above the weighing assembly 1 .

[0041] Here, baffles are arranged at intervals on the surface of the conveyor belt, so that the baffles push the end of the strip material to ensure that it stays accurately above the weighing table of the weighing component to achieve accurate measurement.

[0042] In addition, the baffle can also ensure that the strip materials on each conveyor belt arrive at the top of the weighing component synchronously, so that the weighing operation can be carried out simultaneously, and each conveyor belt can also be driven synchronously by the same motor, reducing computing pressure and equipment operating costs.

[0043] In this embodiment, the central control component 6 obtains the material weight measured by each weighing component 1, and analyzes whether there is any over-limit material whose weight exceeds the qualified weight range.

[0044] In this embodiment, qualified materials within the qualified weight range are output by the conveyor belt 3 to the output end of the weighing component 1, and are guided by the discharge slide rail 4 to slide out.

[0045] In this embodiment, the central control component 6 outputs a rejection instruction to the rejection cylinder 41 corresponding to the weighing component 1 that detects the over-limit material, and drives the rejection cylinder 41 to lift, so that the discharge slide rail 4 installed on the rejection cylinder 41 is in a lifted state.

[0046] In this embodiment, when the discharge slide rail 4 is in a raised state, its input end is higher than the output end of the weighing component 1 .

[0047] Here, in addition to lifting, you can also design reasonable rejection actions based on the actual situation of the production site or the appearance of the material, and implement rejection operations on the material in each channel separately.

[0048] In this embodiment, the over-limit materials output by the weighing assembly 1 fall onto the surface of the rejection conveyor belt 5 for transportation and rejection.

[0049] Here, the rejected oversized materials are also transported away from the drop zone by the rejection conveyor belt to avoid accumulation and facilitate cleaning and transportation.

[0050] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0051] The guide trough with adjustable width feeds the strip materials one by one and conveys them to the top of the weighing component for static weighing, accurately measuring the individual weight of each strip material, and by tilting the discharging slide rail, the non-compliant strip materials fall and are removed. When multiple sets of guide troughs and corresponding weighing components and discharging slide rails are set up, large quantities of strip materials can be weighed and sorted one by one and output to the strip packaging machine, with high operating efficiency and no need for manual intervention.
