Description

Technical Field

[0001] The invention relates to the technical field of rolling auxiliary equipment in the tobacco industry, and in particular to a magnetic buckle for fixing a protective cover of a launch unit of a filter rod launcher. Background Art

[0002] The YF25 filter rod launcher has a total of 10 launch units. The structure of each unit is as shown in the attached figure. Figure 1-2 As shown, the spherical buckle used to fix the protective cover of the launching unit of the filter rod launcher includes a launching unit 1, a protective cover 2, a hinge 3, a spherical buckle 4, a drum wheel 5, a filter rod material bin back plate 6, a material bin door 7, a filter rod 8, an "I"-shaped buckle head 9, a spherical buckle seat 10, and a ball head 11.

[0003] During operation, the protective cover is fixed to the launch unit through the hinge and the ball buckle. The filter rods in the filter rod material library fall into the drum groove through the positioning function of the protective cover. If the protective cover cannot be in place, one end of the filter rod will not be able to enter the drum groove, causing the filter rod to fail to be launched. In actual work, due to the frequent opening of the protective cover, the ball buckle is easy to wear, resulting in the protective cover not being in place and affecting the launch of the filter rod. In order to close the protective cover in place, the operator often hits the protective cover with tools, resulting in the protective cover being easy to break. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings in the prior art and provide a magnetic buckle for fixing the launch unit protective cover of the YF25 filter rod launcher, which is used to replace the spherical buckle and solve the defect that the launch unit protective cover cannot be in place due to the easy wear of the spherical buckle. The structure is simple, the parts processing difficulty is small, the processing and manufacturing cost is low, the various problems caused by the use of the spherical buckle are solved, the service life is extremely long, and it has great promotion value.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 3-4As shown, a magnetic buckle for fixing the protective cover of the launching unit of the filter rod launcher comprises a launching unit 1, a protective cover 2, a hinge 3, a magnetic buckle 4, a drum wheel 5, a filter rod material storehouse back plate 6, a material storehouse door 7, and a filter rod 8. The launching unit 1 is arranged at one end of the drum wheel 5, and the protective cover 2 is arranged at the end of the launching unit 1 away from the drum wheel 5. The protective cover 2 and the launching unit 1 are connected or disconnected through the magnetic buckle 4. The hinge 3 is respectively connected to the launching unit 1 and the protective cover 2. The protective cover 2 is generally in an "L"-shaped structure. An extended bending portion 21 is provided at one end of the "L"-shaped structure. The extended bending portion 21 is adjacent to one side of the drum wheel 5. A filter rod material storehouse back plate 6 and a material storehouse door 7 are provided on this side of the drum wheel 5. The filter rod material storehouse back plate 6 and the material storehouse door 7 are arranged relatively to each other, and a filter rod 8 is placed between the filter rod material storehouse back plate 6 and the material storehouse door 7.

[0027] The magnetic buckle 4 includes an adsorption member seat 41 , an iron adsorption member 43 , and a sheet-like strong magnet 46 . The adsorption member seat 41 is connected to the emitting unit 1 , the sheet-like strong magnet 46 is connected to the protective cover 2 , and the iron adsorption member 43 is connected to the adsorption member seat 41 .

[0028] A through hole 42 is provided in the center / middle part of the adsorption member seat 41, and the through hole 42 is a stepped hole. A threaded rod 44 is provided / connected to one side of the iron adsorption member 43, and a nut 45 is connected to the threaded rod 44, and the nut 45 is a hexagonal nut. A plastic / resin bushing 48 is sleeved on one end of the threaded rod 44 close to the iron adsorption member 43, and the nut 45 is connected to the end of the threaded rod 44 away from the iron adsorption member 43; the axial distance between the nut 45 and the iron adsorption member 43 is greater than the axial width of the bushing 48 or the small diameter hole in the stepped hole, that is, the iron adsorption member 43 has a certain axial displacement.

[0029] A silicone pad / rubber pad 47 is arranged between the sheet-like strong magnet 46 and the protective cover 2, a plurality of first countersunk screw holes 49 are arranged on the adsorption seat 41, and a plurality of second countersunk screw holes 50 are arranged on the sheet-like strong magnet 46. The countersunk screws and the countersunk screw holes are used together for fastening.

[0030] The sheet-like strong magnet is fixed to the protective cover with countersunk screws, and the iron adsorbent is combined with the adsorbent seat by nuts, and the adsorbent seat is fixed to the launch unit by countersunk screws. When the protective cover is close to the launch unit, the magnet and the iron adsorbent are attracted to generate suction. Since the iron adsorbent has a certain movable gap, the sheet-like strong magnet is in full contact with the plane of the iron adsorbent, forming a large magnetic attraction, thereby fixing the protective cover on the launch unit. In order to prevent the magnet from hitting the iron adsorbent and breaking during the adsorption process, a thin silicone pad 47 is added in the middle of the sheet-like strong magnet when it is installed on the protective cover to buffer the impact force and protect the magnet from damage; when the iron adsorbent 43 moves axially, in order to reduce impact and hard wear, a plastic / resin bushing 48 is sleeved on the end of the threaded rod 44 close to the iron adsorbent 43.

[0031] A sheet-shaped strong magnet is installed on the protective cover of the transmitting unit, and an iron adsorption piece is installed at the corresponding position of the transmitting unit and the magnet. When the protective cover is closed in place, the magnet contacts the iron adsorption piece, generating an adsorption force to fix the protective cover on the transmitting unit. Originally, a spherical buckle was used for fixing. Since the protective cover of the transmitting unit needs to be opened and closed frequently, the opening and closing frequency is high. After a period of use, the spherical buckle is easy to wear, causing the protective cover to not be closed in place, or difficult to open, causing the protective cover made of organic glass to be fragile. The magnetic buckle is attracted by magnetic force, the contact surface is not easy to wear, and it is easy to switch. The adsorption piece is a combination part, and the adsorption surface is designed as a movable part with a certain gap to ensure that the magnet is in full contact with the adsorption surface. The magnetic buckle has a simple structure and good use effect. The sheet magnet can be purchased directly at a low price. Because it is magnetically adsorbed, the adsorption piece does not have wear and tear, and the service life is extremely long.

[0032] The magnetic buckle for fixing the protective cover of the filter rod transmitter launch unit has a simple structure, low difficulty in parts processing, low processing and manufacturing cost, solves various problems caused by using spherical buckles, has an extremely long service life, and has great promotion value.

[0033] The above-mentioned implementation modes are for explanation of the present invention rather than limitation of the present invention. It can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
