[0002] As people pursue a healthy life and become more aware of environmental protection, traditional tobacco products are gradually restricted due to the harmful substances produced during their combustion. Heat-not-burn (HNB) tobacco products, as a new tobacco substitute, have attracted widespread attention because they can effectively reduce the release of harmful substances. As one of the core components of HNB tobacco products, the production and testing technology of heat-not-burn filter rods has become an important topic in this field.

On the other hand, in order to ensure the smoking taste, the produced heat-not-burn filter rods need to detect the smoke channel. Smaller and lighter filter rods are also difficult to locate for accurate detection. Summary of the invention

[0020] See also Figures 1 to 9 The present invention provides a production and testing device for a filter rod for a heat-not-burn cigarette, comprising a bottom plate 1, a screw 4 is mounted on the top of the bottom plate 1, a semicircular thread 4a is arranged on the periphery of the screw 4, a material control groove 7 is arranged above the semicircular thread 4a at the rear side, and a material control pipe 9 is arranged above the material control groove 7; The material control groove 7 is provided with a spring sleeve 21, and a material control rod 17 is installed in the spring sleeve 21. The material control rod 17 is sleeved with a spring 18 for periodically feeding the filter rod to facilitate the improvement and detection of the non-combustion performance.

[0021] The rear end of the screw 4 is also provided with a coaxial material control disk 12, on which a material discharge block 12a is provided. When the material control disk 12 rotates, the material discharge block 12a can press a material control rod 17, and the material control rod 17 can push the filter rod in the material control groove 7 into the semicircular thread 4a below. A baffle 6 is provided on the left side of the semicircular thread 4a for longitudinal positioning and sorting of filter rods, so as to facilitate the improvement and detection of non-combustion performance.

[0022] The material control trough 7 is annular, with an opening at the front of the bottom and a closed rear side; The top of the material control groove 7 is open, and an adaptive material control tube 9 is provided on the upper rear side of the top. The material control tube 9 is a hollow cylinder, and a lower material control plate 14 and an upper material control plate 15 are provided on the periphery. The lower material control plate 14 and the upper material control plate 15 are both convex semicircular, and the convex semicircles on the lower material control plate 14 and the upper material control plate 15 can intercept the hollow part of the material control tube 9.

[0023] How it works When in use, the horizontal servo motor and the vertical motor are started synchronously and at the same speed, and the horizontal servo motor drives the screw to rotate; The longitudinal servo motor drives the lower and upper material control plates to rotate; The filter rods will fall into the material control tube from the feed inlet in sequence. The filter rods falling into the material control tube are controlled by the material control plate and fall into the material control slot in sequence and at a fixed time. When the screw rotates, the coaxial material control disk will also rotate synchronously. When the material control disk rotates, the material discharge block on the material control disk will press the material control rod, and the material control rod will press the spring to push the filter rod falling into the material control slot into the semicircular thread, thereby moving the filter rod vertically in sequence.

[0024] The filter rods after positioning and arrangement are very stable, which is convenient for adding flame retardants. Adding flame retardants can not only achieve flame retardancy in materials, but also reduce smoke holes and achieve flame retardancy in structure, thus jointly improving the non-combustibility performance. At the same time, the filter rod in this state and after the process is also convenient for the detection of smoke holes. During the test, the detection aperture can simultaneously detect the added status of the flame retardant and whether the smoke holes will affect the smoking taste, which is very efficient.

[0025] In some embodiments, see Figure 5 and 6 As shown, the material control rod 17 is provided with a limit plate 19; The spring 18 is installed in the spring sleeve 21; The spring 18 is disposed between the limiting plate 19 and the right end surface of the spring sleeve 21, and is sleeved on the periphery of the material control rod 17; The limiting plate 19 is installed in the spring sleeve 21 through the spring cover 20.

[0026] More specifically, when the material control disc rotates, the material discharge block arranged on the material control disc also rotates, and the material discharge block rotates to press the material control rod. After the material control rod is pressed, the spring is compressed under the restriction of the limit disc, and the limit ring is pushed out at the same time, so that the filter rod dropped into the material control groove can be pushed out; When the unloading block rotates, the spring will return to its original state and the control rod will be rebounded by the spring, thus realizing automatic timed unloading.

[0027] In some embodiments, see Figure 5 and 6 As shown, a limiting ring 22 is further provided on the right side of the material control rod 17, and a receiving groove adapted to the limiting ring 22 is provided on the control groove 7; The left side of the material control rod 17 passes through the spring cover 20 and extends to contact the material discharge block 12a. The receiving groove is used to place the limit ring, and the depth of the receiving groove is greater than the thickness of the limit ring. When the spring recovers, the limit ring will not block the falling filter rod.

[0028] In some embodiments, see Figure 1 and 7As shown in FIG. 8 , the height of the lower material control plate 14 and the upper material control plate 15 are consistent with the height of the filter rod. The lower material control plate 14 and the upper material control plate 15 are coaxially arranged and installed on the vertical motor 13 , and the vertical motor 13 is installed on the bottom plate 1 through the support 8 .

[0029] In some embodiments, see Figure 7 As shown, the material control pipe 9 is provided with a cutting groove at the place where it is cut by the lower material control plate 14 and the upper material control plate 15; The material control pipe 9 is clamped on the pipe clamp 10, the pipe clamp 10 is fixed on the bracket 11, and the bracket 11 is installed on the bottom plate 1; A feed inlet 16 is provided at the top of the material control pipe 9 .
