Description

Technical Field

[0001] The invention relates to the technical field of plastic part quality inspection, and in particular to a plastic part sampling quality inspection device. Background Art

[0002] Plastic parts are formed through molds. During the molding process, due to reasons such as mold precision, the weight of each molded plastic part is not consistent, and sampling quality inspection is required. The traditional method involves manually selecting plastic parts and then weighing them, which is inefficient. Some manufacturers require automated devices to achieve automatic sampling and inspection equipment.

[0003] Chinese patent CN211194880U discloses a product weighing and detection device for a blow molding machine. The device has a loading area and a weighing area; blow-molded products are loaded into the loading area and weighed in the weighing area. A weighing sensor feeds the actual weight of the blow-molded products to a controller, which compares this weight with an internally preset weight threshold. However, the device randomly selects plastic parts for weighing, and therefore cannot accurately reflect the quality of the entire batch of plastics.

[0004] Therefore, it is necessary to develop a plastic parts sampling quality inspection equipment to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-precision plastic parts sampling quality inspection device.

[0007] Conveying device for transporting plastic;

[0008] The material passing sensing device includes a sensing part and a limit assembly. The limit assembly is arranged above the conveying device and gathers the plastic into the sensing range of the sensing part. The sensing part detects the number of plastic parts passing through the sensing part.

[0009] a clamping assembly for clamping and delivering one of the plastic parts in a batch of plastic parts passing through the sensing portion;

[0010] The weighing part includes a tiltable electronic scale, which measures the weight of the plastic part clamped by the clamping assembly.

[0011] Furthermore, the material passing sensing device includes a first bracket and a driving part installed on the first bracket, and the sensing part is driven by the driving part.

[0013] Furthermore, the limiting assembly includes fixing parts located on both sides of the conveying device and limiting plates connected to the fixing parts, and the limiting plates are located above the conveying device.

[0014] Furthermore, the limiting plates are in a pair and are arranged opposite to each other, with one end thereof extending toward the sensing portion, and the distance between the ends of the pair of limiting plates extending toward the sensing portion is smaller than the distance between the other ends thereof.

[0015] Furthermore, the weighing part includes a driving cylinder, a driving rod connected to the driving cylinder, and a base installed at the end of the driving rod, and the electronic scale is installed on the base.

[0016] Furthermore, the weighing part also has a supporting part, which is used to support the driving cylinder and the electronic scale. The driving cylinder is fixed below the supporting part, and the electronic scale is located above the supporting part and adjacent to the conveying device.

[0017] Furthermore, the driving cylinders are a pair, which drive one side of the electronic scale to move upward or downward, so that the electronic scale is tilted and the plastic parts on the electronic scale slide down.

[0018] Furthermore, one side of the electronic scale is a qualified area, and the other side is a unqualified area. After the electronic scale detects the weight of the plastic part, it tilts in different directions according to whether the plastic part is qualified.
