Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically to a filter rod selection device with adjustable light source. Background Technology

[0002] Internal defects in the filter rod (such as impurities, uneven forming, etc.) directly affect product quality.

[0003] Limited light source: Existing technologies generally use light sources with a single color temperature or fixed spectrum, which cannot be dynamically adjusted according to the color of different filter rod forming paper (such as white, yellow, and blue), resulting in some defects being missed due to insufficient light contrast.

[0004] The brightness is not adjustable: a fixed brightness light source can easily cause visual fatigue to the operator during long-term testing, reducing testing efficiency; at the same time, it is impossible to optimize the light intensity for different filter rod materials (such as high light transmittance or frosted materials), which affects the testing accuracy.

[0005] Poor adaptability: Traditional equipment lacks intelligent adjustment functions, making it difficult to adapt to the diverse production needs of filter rods, resulting in a high rate of missed detections. For example, fine impurities in light-colored filter rods are difficult to identify under single white light, while internal defects in dark-colored filter rods may be concealed due to reflectivity. Utility Model Content

[0006] The purpose of this invention is to solve the problems mentioned above in the background technology and to propose a filter rod selection device with adjustable light source.

[0007] The objective of this utility model can be achieved through the following technical solutions:

The filter rod can be placed on the light-transmitting plate and detected under the illumination of the light sources. The light sources are multi-color adjustable light sources.

[0009] As a further embodiment of this utility model, the light source is an LED light source module.

[0010] As a further embodiment of this utility model, the light-transmitting plate is made of acrylic material.

[0011] As a further embodiment of this utility model, the surface of the light-transmitting plate is frosted.

[0012] As a further embodiment of this utility model: a limiting frame is provided at the tail end of the frame, and the limiting frame can slide vertically on the frame.

[0013] As a further embodiment of this utility model: a limiting rod is vertically fixed at the bottom of the frame, and a hole is provided on the limiting frame near the limiting rod, through which the limiting frame can slide on the limiting rod.

[0014] As a further embodiment of this utility model: a spring is sleeved on the limiting rod, one end of the spring is fixed to the frame, and the other end of the spring is fixed to the limiting frame.

[0015] As a further embodiment of this utility model, the filter rod selection device also includes a mechanical pedal, which is disposed below the frame and can drive the limiting frame to slide on the frame.

[0016] As a further embodiment of this utility model: a pull rod is also provided between the mechanical pedal and the limiting frame, one end of the pull rod is rotatably connected to the mechanical pedal, and the other end of the pull rod is rotatably connected to the limiting frame.

[0017] As a further aspect of this utility model: the LED light source module supports independent adjustment of any one or more of red, green, blue or white light, with a color temperature range of 2000K-6500K.

[0018] The beneficial effects of this invention are as follows: A multi-color adjustable light source system: Utilizing an RGBW four-color LED module, it supports independent adjustment and mixed output of red, green, blue, and white light, with a color temperature range covering 2000K-6500K. Through preset modes (such as enabling high-contrast blue light for yellow filter sticks), the defect recognition rate of different colored filter sticks can be significantly improved, especially increasing the sensitivity for detecting minute impurities in light-colored filter sticks by more than 30%.

[0019] Stepless dimming control technology: Integrating stepless adjustment of brightness (10%-100%) and color temperature, operators can quickly optimize lighting conditions according to the filter rod material and testing requirements. For example, frosted filter rods use low-brightness soft light to reduce reflections, while high-transmittance materials use high-brightness light sources to enhance the contrast of internal defects, reducing the false negative rate by 25%.
