Description

Technical Field

[0001] The utility model relates to the technical field of filter rod production equipment, in particular to a filter rod charging device. Background Art

[0002] Cigarette filter rods are the core key material of filter-tipped cigarettes. After the cigarette filter rods are produced by the filter rod forming machine, they need to be loaded into the material tray (also called the material box) through the filter rod loading device. When the material tray is full of filter rods, the material tray full of filter rods is transported to the downstream equipment for processing through the conveyor belt. At the same time, the empty material tray enters the discharge port of the filter rod loading device for loading processing.

[0003] During the switching of the trays, the feed opening of the filter rod loading device needs to be closed to prevent the filter rod from falling during the switching of the trays. The closing time is generally 1 to 2 seconds. However, in actual production activities, the existing filter rod loading device is prone to squeezing the filter rod, causing the filter rod to deform, or the feed opening cannot be well closed, causing the filter rod to fall during the switching of the trays.

[0004] Therefore, how to avoid the filter rod from being squeezed and deformed and to improve the sealing effect of the feed port has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0041] Examples, such as Figure 1-Figure 5 As shown, a filter rod charging device comprises:

[0042] Rack 100.

[0043] A filter rod storage chamber 200 is provided on the frame 100, and is used to store the filter rods 700 outputted by the filter rod forming machine; a feed port 210 is formed on the upper end surface of the filter rod storage chamber 200, and the feed port 210 is used for the filter rods 700 outputted by the filter rod forming machine to enter the filter rod storage chamber 200; a discharge port 220 is formed on the lower end surface of the filter rod storage chamber 200, and the discharge port 220 is used for the filter rods 700 to be discharged from the filter rod storage chamber 200.

[0044] The diverter row 300 is installed below the discharge port 220 and is fixedly connected to the frame 100. The diverter row 300 has a plurality of discharge channels 310 spaced apart along the transverse direction, and the transverse dimension of the discharge channel 310 is larger than the radial dimension of the filter rod 700, so that the filter rods 700 in the filter rod storage chamber 200 can be discharged from the discharge port 220 more evenly and neatly.

[0045] The intercepting row 400 includes a plurality of intercepting rods 410 that are laterally spaced and distributed, and an intercepting ball 420 is rotatably mounted on the intercepting rod 410. An avoidance channel 430 that cooperates with the discharge channel 310 is formed between two adjacent intercepting rods 410, and the intercepting row 400 is arranged below the diverter row 300 so as to be able to move back and forth laterally, so that the avoidance channel 430 is opposite to or offset from the discharge channel 310, thereby realizing the opening and closing of the discharge channel 310 of the diverter row 300.

[0046] The material box conveyor belt 500 is longitudinally arranged below the interception row 400, and the filter rod material box 600 for containing the filter rod 700 is placed on the material box conveyor belt 500, so that the empty filter rod material box 600 can be conveyed to the bottom of the discharge port 220 through the longitudinal transmission of the material box conveyor belt 500, and the filter rod material box 600 filled with filter rods 700 can be conveyed to the downstream equipment.

[0047] The present application installs an intercepting row 400 capable of transverse reciprocating movement below the diverter row 300, and the opening or closing of the feed channel 310 of the diverter row 300 is realized by the transverse movement of the intercepting row 400, thereby improving the sealing effect of the feed port 220 and preventing the filter rod 700 from falling during the switching process of the filter rod material box 600; at the same time, each intercepting rod 410 of the intercepting row 400 is installed with a rotatable intercepting ball 420, and when the intercepting row 400 closes the feed channel 310 of the diverter row 300, the intercepting ball 420 forms a rolling friction with the filter rod 700 located in the feed channel 310, thereby effectively avoiding the extrusion deformation of the filter rod 700 caused by the intercepting row 400, thereby ensuring the quality of the filter rod.

[0048] In a specific embodiment, if Figure 3 As shown, the interception row 400 includes an interception rod 410, an interception ball 420 and an interception support cross bar 440, the interception support cross bar 440 is arranged in the transverse direction, the number of the interception rod 410 is multiple, and the multiple interception rods 410 are linearly distributed at equal intervals in the transverse direction, and one axial end of the interception rod 410 is vertically fixedly connected to the interception support cross bar 440, and an avoidance channel 430 is formed between two adjacent interception rods 410. The number of the interception ball 420 is multiple, and the interception ball 420 and the interception rod 410 are in a one-to-one correspondence. The interception ball 420 can be rotatably sleeved in the middle of the interception rod 410, and the interception ball 420 is made of nylon with a friction coefficient of 0.15-0.3.

[0049] Specifically, the outer diameter of the intercepting ball 420 is 8 mm, the inner diameter of the intercepting ball 420 is 5.3 mm, and the length of the intercepting ball 420 is 19.6 mm, which effectively improves the friction coefficient of the intercepting ball 420, increases the friction between the intercepting ball 420 and the filter rod 700, and improves the intercepting effect of the intercepting row 400 on the filter rod 700.

[0050] Preferably, the material of the intercepting rod 410 is 1Cr18Ni9Ti, and the diameter of the intercepting rod 410 is 5 mm, which can effectively increase the bending strength of the intercepting rod 410 and prevent the intercepting rod 410 from being squeezed and deformed by the filter rod 700 and causing the filter rod 700 to fall off.

[0051] It should be noted that a driving mechanism (not shown) is installed on the frame 100, which is connected to the intercepting bar 400 and is used to drive the intercepting bar 400 to move back and forth laterally. The driving mechanism can adopt any known power mechanism, such as a cylinder or a driving motor in combination with a transmission mechanism.

[0052] In a specific embodiment, if Figure 1 and Figure 2 As shown, the filter rod storage chamber 200 is in the shape of an inverted funnel that is small at the top and large at the bottom.

[0053] Preferably, the filter rod storage chamber 200 is enclosed by a front side panel 230, a right side panel 240, a rear side panel 250 and a left side panel 260. The front side panel 230 is a double-opening glass door, which is not only convenient for observing the unloading of filter rods 700 in the filter rod storage chamber 200, but also convenient for opening the filter rod storage chamber 200 to clean or inspect and maintain the filter rod storage chamber 200.

[0054] More preferably, a feed guide inclined plate 270 is installed above the filter rod storage chamber 200, the feed guide inclined plate 270 is connected to the feed port 210, and the feed guide inclined plate 270 is inclined above the filter rod storage chamber 200, and is used to guide the filter rod 700 delivered by the filter rod forming machine into the filter rod storage chamber 200 to ensure the stability of the feed.

[0055] In a specific embodiment, if Figure 1 and Figure 2 As shown, the diverter row 300 includes a diverter support cross bar 330 and a diverter rod 320. The diverter support cross bar 330 is arranged in the transverse direction. The number of the diverter rods 320 is multiple, and the multiple diverter rods are linearly distributed at equal intervals in the transverse direction. One axial end of the diverter rod 320 is fixedly connected to the diverter support cross bar 330, and a feed channel 310 is formed between two adjacent diverter rods 320. The transverse dimension of the feed channel 310 is larger than the radial dimension of the filter rod 700, so that the filter rod 700 in the filter rod storage chamber 200 falls evenly through the feed channel 310 after passing through the feed port 220.

[0056] The working process of the filter rod charging device of the present application is as follows:

[0057] like Figure 4 and Figure 5 As shown, when the intercepting row 400 closes the feeding channel 310 of the diversion row 300, the intercepting rod 410 of the intercepting row 400 moves laterally to the bottom of the feeding channel 310. At this time, rolling friction is formed between the intercepting ball 420 on the intercepting rod 410 and the outer peripheral surface of the filter rod 700 located in the feeding channel 310, which can prevent the intercepting rod 410 from causing extrusion deformation of the filter rod 700; at the same time, the friction force provided by the intercepting ball 420 is greater than or equal to the sum of the positive pressure and the shear force exerted on the filter rod 700, which can effectively prevent the filter rod 700 located in the feeding channel 310 from falling.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
