Description

Technical Field

[0001] This utility model relates to the field of plastic tableware processing technology, specifically to an automatic weighing machine for plastic tableware. Background Technology

[0002] Different types of plastic tableware may require different combinations and proportions of raw materials. When manually transferring materials, operators need to move the raw materials from the storage area to the weighing area. This involves multiple back-and-forth movements, especially when producing various types of plastic tableware and requiring multiple combinations of raw materials. The operation is complex and time-consuming. During the weighing process, data needs to be recorded after each weighing before preparing the raw materials for the next weighing. This process involves a large number of intermittent operations and is quite inconvenient. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic weighing machine for plastic tableware.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic weighing machine for plastic tableware, comprising a weighing component, a connecting component, and a transfer component. The weighing component includes a base plate, a measuring device, and a load platform. The measuring device is embedded in the center of the upper part of the base plate, and an I-shaped load platform is arranged above the measuring device. The transfer component includes a feeding hopper, a support frame, a support plate, a transfer box, a first motor, an auger, a feed pipe, and a discharge pipe. Two sets of support frames are symmetrically arranged below the feeding hopper. The support frames are in the shape of an open-top C-shape, and the bottom wall of the support frame is fixed to the support plate. The feeding hopper is connected to the transfer box via the feed pipe. An auger is arranged inside the transfer box. The output end of the first motor passes through the transfer box and is connected to the auger. The other end of the transfer box protrudes from the base plate, and the discharge pipe is arranged below the other end of the transfer box. The support frame is connected to the upper part of the load platform via the connecting component.

[0007] To facilitate the assembly and disassembly of the material transfer assembly and the load-bearing platform, this utility model is improved in that the connecting component includes a second motor, a threaded rod, and a clamping plate. The bottom wall of the support frame is provided with a sliding groove, and the threaded rod is disposed in the sliding groove. Two sets of symmetrically arranged clamping plates for clamping the side wall of the load-bearing platform are provided below the support frame. The clamping plates are slidably connected to the sliding groove. The upper part of the clamping plate is provided with a threaded hole for threaded connection with the threaded rod. The output end of the second motor passes through the support frame and is connected to the threaded rod.

[0008] To ensure the stability of the connection between the clamping plate and the load-bearing platform, the present invention is improved in that the clamping plate is L-shaped, and the center of the bottom wall of the clamping plate is provided with a notch that matches the center beam of the load-bearing platform. The lower part of the top wall of the load-bearing platform is attached to the upper part of the bottom wall of the clamping plate.

[0009] Preferably, the notch is further rounded on both sides.

[0010] To provide stable support for the material transfer assembly, this utility model is improved by providing support legs at the four corners below the support plate. The bottom wall height of the support legs is higher than the bottom wall height of the load-bearing platform, and the bottom wall height of the support legs is lower than the bottom wall height of the clamping plate.

[0011] Preferably, the base plate has mounting holes at its four corners.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an automatic weighing machine for plastic tableware, which has the following advantages:

[0014] This automatic weighing machine for plastic tableware features a weighing unit with the measuring device embedded in the center of the base plate, and an "I"-shaped load platform above it. This structural design ensures a more even distribution of force on the load platform, accurately transferring the weight of the material to the measuring device during the weighing process and guaranteeing weighing accuracy.

[0015] The auger inside the transfer box is driven by a first motor, effectively conveying materials from the feeding hopper through the feed pipe to the transfer box, and then transferring them to the next process through the discharge pipe. The auger's spiral structure can adapt to different types of plastic raw materials, whether granular or powdered, ensuring smooth transfer and maintaining the continuity and stability of the transfer process. This helps improve the overall efficiency of plastic tableware production. During this process, the meter calculates the difference, i.e., the feeding weight. When the feeding threshold is reached, the first motor stops, and the transfer box stops feeding. The first motor is a precisely controlled servo motor.

[0016] The material transfer assembly is detachably connected to the load-bearing platform via connectors, facilitating disassembly, assembly, maintenance, and inspection, and making it easy to use. Attached Figure Description
