Description

Technical Field

[0001] The utility model relates to the technical field of pen barrel injection molding processing, in particular to a convenient blanking and conveying device for pen barrel injection molded parts. Background Technique

[0002] As is well known, in the process of pen barrel processing, injection molding is required. After molding, the injection molded parts need to be transported through a blanking and conveying device to facilitate subsequent processing steps. As the prior art of the injection molded part blanking and conveying device, the Chinese Patent Network discloses a conveying device for injection molded part processing with the publication number of CN221365720U, which includes a bracket and a conveying roller shaft. Inside the bracket, a blanking platform and a feeding platform are symmetrically fixed. Gravity sensing pads are fixed on the top surfaces of the blanking platform and the feeding platform. Above the two gravity sensing pads, aggregate boxes are arranged. On the inner sides of the brackets beside the two gravity sensing pads, support plates are fixed. On the support plate on the side of the blanking platform, a first motor is fixed. On the support plate on the side of the feeding platform, a second motor is fixed. The output ends of the first motor and the second motor are both fixed with rotating shafts, and on each rotating shaft, a dial rod is fixed. By detecting the loading and unloading of the injection molded parts during the transmission process of the injection molded parts, the transmission is carried out after the aggregate box is loaded and unloaded, avoiding the phenomenon of empty boxes, improving the transmission efficiency, avoiding the idling of the equipment, and improving the processing efficiency.

[0003] However, when using the existing injection molded part conveying device to carry out blanking and conveying of pen barrel injection molded parts such as ballpoint pens, it mainly relies on the gravity sensing pad to sense the weight change of the aggregate box, so as to carry out the blanking and conveying work after removing the obstruction of the aggregate box. However, the gravity sensing pad will be damaged due to factors such as environmental humidity, electromagnetic interference, and physical damage. Since the existing conveying device is directly fixed to the gravity sensing point, it is not possible to more conveniently disassemble, install, and replace the damaged gravity sensing pad in a timely manner. For this reason, we propose a convenient blanking and conveying device for pen barrel injection molded parts. Content of the Utility Model
