Description

Technical Field

[0001] The invention belongs to the technical field of cigarette making machine parts and components and relates to a floating ring in a cigarette making machine. Background Art

[0002] At present, the floating ring structure in the market basically includes a fixed ring, a circular gathering plate outside the fixed ring, and a ring-shaped rubber body connected between the fixed ring and the circular gathering plate. The floating ring is an important component in the cigarette making machine. It is mainly used in conjunction with the paper separation wheel or integrated wheel in the cigarette making machine. The basic process is to fix two floating rings at the two ends of the paper separation wheel or integrated wheel through fixed rings respectively. During the entire process of the floating ring rotating with the paper separation wheel or integrated wheel, the circular gathering plates on the two floating rings are used to produce the same angle but opposite inclination to ensure that the doubled cigarettes are arranged neatly for accurate cutting (this function is used in conjunction with the paper separation wheel) or to make the cigarettes and filters closely match (this function is used in conjunction with the integrated wheel).

[0003] However, the fixing ring and the circular gathering plate are both made of metal, which means that they must either be glued together or the fixing ring and the circular gathering plate must be placed in a mold during production, and then liquid rubber must be injected into the mold. After cooling, the liquid rubber becomes a rubber body and is fixed to the fixing ring and the circular gathering plate as a whole. Since the inclination of the circular gathering plate depends on the deformation of the rubber body itself, when the circular gathering plate is working, it will continue to generate tension on the connection between the rubber body and the fixing ring, so that the rubber body and the fixing ring are easily separated, which means that its service life is relatively short. In addition, after the rubber body is separated from the fixing ring, it cannot be re-fixed, and a new floating ring can only be replaced, which will increase the company's production costs.

[0004] In view of the short service life, it is easy for those skilled in the art to think of opening a round hole on the fixing ring and injecting liquid rubber into the round hole during the one-piece molding, so as to increase the contact area and connection strength between the rubber body and the fixing ring, such as the cigarette making machine floating ring device disclosed in patent application No. 200520087738.2 and the cigarette making machine floating ring disclosed in patent application No. 200820117629.4; another way is to select a rubber material that can form a stronger connection force after cooling. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and propose a floating ring in a cigarette making machine to solve the problem of short service life.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The floating ring in the cigarette making machine includes a fixed ring, a circular ring gathering plate located outside the fixed ring, and a connecting piece fixed between the fixed ring and the circular ring gathering plate. The characteristic is that the connecting piece is made of spring steel, and the connecting piece includes a ring-shaped thin plate-shaped base plate and a plurality of elastic protrusions fixedly connected to the inner circumferential wall of the base plate. Each elastic protrusion is in a long strip shape, each elastic protrusion is close to the inner circumferential wall of the base plate and there is a gap between the two. The base plate part abuts against the circular ring gathering plate and the two are fixed by a fastener. Each elastic protrusion is evenly distributed around the fixed ring, and each elastic protrusion is fixed to the fixed ring by a fastener.

[0008] The fixing ring, the circular ring gathering plate and the connecting piece are combined with the fastener 1 and the fastener 2 to form a complete structure of the floating ring. When used on a cigarette making machine, two floating rings are required. The two assembled floating rings are respectively put on the two ends of the paper separation wheel or the integrated wheel of the cigarette making machine through the fixing ring, and then the two fixing rings are fixed to the paper separation wheel or the integrated wheel by the locking screw. The opposite sides of the circular ring gathering plates in the two floating rings cooperate with the top pressing mechanism in the cigarette making machine. Under the action of the top pressing mechanism, the same position of the two circular ring gathering plates is subjected to the extrusion force and overcomes the elasticity of the connecting piece to approach each other, that is, the two circular ring gathering plates are tilted at the same angle but in the same direction to meet the use.

[0009] The float ring adopts spring steel to make the connector and sets the connector to include a base plate and a plurality of elastic protrusions fixed on the basic inner wall. The existence of each elastic protrusion enables a certain position on the circular ring gathering plate to tilt relative to the fixed ring when a force is applied to ensure the required special requirements, and each elastic protrusion is fixed on the inner wall of the base plate so that the entire connector has a sufficiently high mechanical strength and integrity, and is not easy to break during use. In addition, since the fixed ring and the circular ring gathering plate are both made of metal materials, and the use of spring steel as the raw material enables the connector and the fixed ring to be directly fixed by fastener 2, and the connector and the circular ring gathering plate to be directly fixed by fastener 1, so that the connection is more secure, especially between the connector and the fixed ring, and even if fastener 1 or fastener 2 is loose, it can be overcome by re-tightening, which greatly extends the service life of the float ring. And when the connector's own elasticity is weakened due to the increasing number of uses, the staff can also replace only the connector by removing fastener 1 and fastener 2, which also greatly reduces the cost. The strip-shaped structure enables the elastic protrusion to have better deformation ability, and the circular ring gathering plate can be deformed more smoothly when subjected to force to meet the requirements of use.

[0010] In the floating ring of the above-mentioned cigarette making machine, the elastic protrusion is an arc-shaped long strip.

[0011] The arc-shaped strip allows the elastic protrusion to have a larger deformation range, so that the circular ring gathering plate has a larger tilting range and has higher practicality.

[0012] In the above-mentioned floating ring in the cigarette making machine, the base plate and each elastic protrusion are an integrated structure, and the elastic protrusion is processed by wire cutting.

[0013] Each elastic protrusion and the substrate are an integrated structure and the elastic protrusion is processed by wire cutting, so the structural strength between the elastic protrusion and the substrate is higher. At the same time, after cutting, the above-mentioned gap is naturally formed between the elastic protrusion and the substrate to ensure that the elastic protrusion can be deformed so that the circular ring gathering plate tilts when a certain position is subjected to force.

[0014] In the floating ring of the above-mentioned cigarette making machine, a concave groove communicating with the gap is provided between the root of the elastic protrusion and the inner peripheral wall of the base plate.

[0015] In the floating ring of the above-mentioned cigarette making machine, the inner side wall of the elastic protrusion and the inner peripheral wall of the base plate form an arc transition.

[0016] The concave groove ensures that the elastic protrusion has sufficient deformation ability, and at the same time, the arc transition between the inner side wall of the elastic protrusion and the inner peripheral wall of the base plate ensures the overall structural strength of the entire connecting piece.

[0017] In the floating ring of the above-mentioned cigarette making machine, the outer side of the fixed ring is provided with an annular lug, and the end of each elastic protrusion has a lug extending toward the axis of the fixed ring. Each lug abuts against the annular lug and is fixed by the above-mentioned fastener.

[0018] During assembly, the lugs on each elastic protrusion are placed against the annular lugs on the outside of the fixing ring, and then the lugs and the annular lugs are fixed together by fastener 2. The arrangement of the lugs enables the elastic protrusions and the fixing ring to have a fixed position, so that the annular gathering plate can be tilted by virtue of the deformation of the elastic protrusions when a force is applied.

[0019] Compared with the prior art, the floating ring in the cigarette making machine has the following advantages:

[0020] 1. By using spring steel to make the connector, and setting the connector to include a base plate and a plurality of elastic protrusions fixedly connected to the basic inner circumferential wall, the annular gathering plate can be tilted relative to the fixing ring to meet the required special requirements, and each elastic protrusion is fixedly connected to the inner side wall of the base plate so that the entire connector has sufficiently high mechanical strength and integrity, and is not prone to breakage during use;

[0021] 2. The use of spring steel as the raw material enables the connecting piece and the fixing ring to be directly fixed by fastener 2, and the connecting piece and the annular gathering plate to be directly fixed by fastener 1, which makes the connection firmer, especially between the connecting piece and the fixing ring, and even if fastener 1 or fastener 2 is loose, it can be overcome by re-tightening, which greatly extends the service life of the floating ring.

[0022] 3. When the elasticity of the connector is weakened due to increasing frequency of use, the staff can replace only the connector by removing fastener 1 and fastener 2, which greatly reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1 and Figure 2 As shown, the floating ring in the cigarette making machine includes a fixed ring 1, a circular ring gathering plate 2 located outside the fixed ring 1, and a connecting member 3 fixed between the fixed ring 1 and the circular ring gathering plate 2. The fixed ring 1 and the circular ring gathering plate 2 are both made of metal materials, and the connection is made of spring steel. The connecting member 3 specifically includes a circular thin plate-shaped base plate 3a and a plurality of elastic protrusions 3b fixedly connected to the inner peripheral wall of the base plate 3a. Each elastic protrusion 3b is an integral structure with the base plate 3a. The base plate 3a partially abuts against the circular ring gathering plate 2 and the two are fixed by a fastener 14. Each elastic protrusion 3b is evenly distributed around the fixed ring 1, and each elastic protrusion 3b is fixed to the fixed ring 1 by a fastener 25.

[0028] like Figure 1 and Figure 2As shown, the elastic protrusion 3b is in the shape of a strip, specifically an arc-shaped strip, and the elastic protrusion 3b is close to the inner peripheral wall of the substrate 3a and there is a gap 3c between the two. The elastic protrusion 3b is specifically processed by wire cutting, and the wire cutting method naturally forms a gap 3c between the elastic protrusion 3b and the inner peripheral wall of the substrate 3a. There is a concave groove 3d connected to the gap 3c between the root of the elastic protrusion 3b and the inner peripheral wall of the substrate 3a. The inner edge of the annular gathering plate 2 corresponds to the concave groove 3d, and there is an arc transition between the inner side wall of the elastic protrusion 3b and the inner peripheral wall of the substrate 3a. The outer side of the fixing ring 1 has an annular lug 1a, and the end of each elastic protrusion 3b has a convex piece 3b1 extending toward the axis of the fixing ring 1. Each convex piece 3b1 abuts against the annular lug 1a and is fixed by a fastener 25. The fastener 1 4 and the fastener 2 5 can be common hardware accessories such as screws, bolts, rivets, etc. for fixing two parts. In order to cooperate with the fastener 1 4, a plurality of mounting holes 1 3a1 are evenly arranged on the substrate 3a along the circumferential direction; in order to cooperate with the fastener 2 5, each protruding piece 3b1 is penetrated by a mounting hole 2 3b11.

[0029] During processing, a thin plate made of spring steel is taken, and then the thin plate of spring steel is processed by wire cutting to form a connecting member 3 consisting of a base plate 3a and a plurality of elastic protrusions 3b. There will be a gap 3c between the inner peripheral wall of the base plate 3a and the outer side wall of each elastic protrusion 3b after cutting. The existence of the gap 3c and the shape of the elastic protrusion 3b itself make the elastic protrusion 3b have better elasticity, so that when a certain position on the annular gathering plate 2 is subjected to a force, it can deflect with the help of the elasticity of the connecting member 3 to meet its normal use requirements.

[0030] The fixing ring 1, the circular ring gathering plate 2 and the connecting member 3 are combined into a complete structure of a floating ring by using the fastener 1 4 and the fastener 2 5. Two floating rings are needed when used on a cigarette making machine. The two assembled floating rings are respectively put on the two ends of the paper separation wheel or the integrated wheel of the cigarette making machine through the fixing ring 1, and then the two fixing rings 1 are fixed together with the paper separation wheel or the integrated wheel by using the locking screws. The opposite sides of the circular ring gathering plates 2 in the two floating rings cooperate with the top pressing mechanism in the cigarette making machine. Under the action of the top pressing mechanism, the same position of the two circular ring gathering plates 2 is subjected to the extrusion force and overcomes the elasticity of the connecting member 3 to approach each other, that is, the two circular ring gathering plates 2 are tilted at the same angle but in the same direction to meet the use requirements.

[0031] The floating ring adopts spring steel to make the connecting member 3, and the connecting member 3 is configured to include a base plate 3a and a plurality of elastic protrusions 3b fixedly connected to the basic inner peripheral wall. The characteristics of the spring steel make the connecting member 3 have sufficient mechanical strength, and at the same time, when a certain position on the annular gathering plate 2 is subjected to force, it can be tilted by means of the elasticity of the connecting member 3 itself to ensure the required use requirements.

[0032] In addition, since the fixing ring 1 and the annular gathering plate 2 are both made of metal materials, and the use of spring steel as the raw material enables the connection member 3 and the fixing ring 1 to be directly fixed by the fastener 2 5, and the connection member 3 and the annular gathering plate 2 to be directly fixed by the fastener 1 4, so that the connection is more secure, especially between the connection member 3 and the fixing ring 1, and even if the fastener 1 4 or the fastener 2 5 is loose, it can be overcome by re-tightening, which greatly extends the service life of the float. And when the elasticity of the connection member 3 is weakened due to the increasing number of uses, the staff can also replace only the connection member 3 by removing the fastener 1 4 and the fastener 2 5, which also greatly reduces the cost.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
