Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette production equipment, and in particular relates to a cigarette rejecting device before rubbing and joining used in a cigarette making machine. Background Art

[0002] At present, the equipment for producing slim cigarettes in the tobacco industry is generally the ZJ17 type cigarette making machine. When making cigarettes, double-length cigarettes are generally delivered to the cigarette maker to be cut into two equal-length cigarettes, and then separated by a certain distance, and the filter section is placed in the middle to form a "group cigarette", and then glued with a piece of cork paper coated with glue, and then the rubbing drum wheel and the rubbing board cooperate to rub and splice into double-length filter cigarettes, and then cut into two single-length filter cigarettes. Therefore, the rubbing board is the most important executive part in the cigarette maker.

[0003] After the equipment is started, the PLC controls the collection of various raw and auxiliary materials required for the formation of filter cigarettes (except for the tipping paper) on the approaching drum of the assembler, and then transfers them to the splicing drum to cooperate with the washboard to complete the splicing and forming. Due to the different time, position, distance of the various raw and auxiliary materials involved and the different material properties of the auxiliary materials, there will be slight time differences and flatness differences in the raw and auxiliary materials transferred to the splicing drum, which will cause repeated blockage of the washboard. The original residual smoke removal device of the equipment is installed on the final cutting drum. After the washboard is spliced ​​and formed, the original machine's removal device can only remove residual smoke after the splicing is completed, and it is impossible to clean the residual cigarettes before splicing, which increases the frequency of clogging of the washboard. Summary of the invention

[0004] The utility model provides a cigarette rejecting device before rubbing and splicing for a cigarette making machine, which can reject defective cigarette groups that do not meet the rubbing and splicing requirements before a rubbing board, thereby greatly reducing the frequency of clogging of the rubbing board.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a cigarette rejection device before splicing for a cigarette making machine, comprising an arc-shaped rejection model component, wherein the arc-shaped rejection model component is installed on the reinforcing ribs of the splicing drum wheel air valve, and the arc-shaped rejection model component is located between the splicing drum wheel air valve and the splicing drum wheel; the arc-shaped rejection model component is provided with air holes corresponding to the splicing drum wheel, and the air holes are connected to the air supply equipment.

[0006] The arc-shaped rejection model component includes an outer layer component and an inner layer component; the outer layer component is an arc-shaped plate, the arc of which corresponds to the inner surface of the splicing drum, and 5 special-shaped protrusions are arranged on the outer arc surface of the arc-shaped plate, the special-shaped protrusions are relatively close to the inner wall of the splicing drum, and the 5 special-shaped protrusions are spaced apart to form an air control duct connected to the negative pressure inside the splicing drum;

[0007] Each special-shaped protrusion is provided with an air hole and a rounded air collecting concave circle, and the air holes on the five special-shaped protrusions correspond to a group of holes on the splicing drum wheel; the lower part of the air hole of each special-shaped protrusion corresponds to a rounded air collecting concave circle that is not connected to the air hole, and the rounded air collecting concave circle is arranged along the circumferential direction of the splicing drum wheel; the inner layer component is provided with an air duct connected to the air hole, and the air duct is connected to the air storage tank through an air pipe, and is controlled to be on and off by an electromagnetic valve.

[0008] The solenoid valve is controlled by a PLC controller.

[0009] The arc-shaped rejection model component and the reinforcing rib are positioned and installed by countersunk bolts, and the outer layer component and the inner layer component are positioned and connected by countersunk bolts.

[0010] The top of the special-shaped protrusion is rounded, with an air hole in the middle and a rounded air-collecting concave circle at the bottom. The width of the rounded air-collecting concave circle corresponds to the diameter of the upper air hole. The rounded air-collecting concave circle extends along the circumferential direction of the splicing drum to the edge of the special-shaped protrusion, so that the rounded air-collecting concave circle is connected to the negative pressure inside the splicing drum.

[0011] The five special-shaped bumps are arranged symmetrically on the left and right, and are special-shaped bump I, special-shaped bump II, special-shaped bump III, special-shaped bump II, and special-shaped bump I in sequence.

[0013] The special-shaped protrusion II has two rounded air collecting concave circles, one corresponding to the small hole and the other corresponding to the middle hole.

[0014] The arc-shaped rejection model component is installed at the 90°-135° position of the twisting drum wheel air valve.

[0015] The shape rejection model component is installed on the drum wheel air valve at the counterclockwise position of 95°-115° before the twisting and splicing.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 The device for rejecting cigarettes before splicing for a cigarette making machine shown in the figure comprises an arc-shaped rejecting model component 1.

[0023] like Figure 2-3 As shown, the arc-shaped rejection model component 1 is installed on the reinforcing rib 2-1 of the splicing drum wheel air valve 2. Preferably, the arc-shaped rejection model component 1 is installed at the 90°-135° position of the splicing drum wheel air valve 2, or is installed on the splicing drum wheel air valve 2 at the 95°-115° counterclockwise position before splicing. Because in the process of rejecting incomplete cigarette groups, the inertia of the turnover will bring the incomplete cigarette group into the scrubbing board, and the arc-shaped rejection model component 1 is installed inside the splicing drum wheel, so the arc-shaped rejection model component 1 is installed here. It will not affect the various functions of the original machine, and at the same time, it can provide a guarantee for the reliability of rejection and the improvement of equipment efficiency.

[0024] The outer cover of the rubbing drum wheel air valve 2 is as follows Figure 4 The rubbing drum wheel 3 shown in the figure is coaxial with the rubbing drum wheel air valve 2, and the rubbing drum wheel 3 rotates outside the rubbing drum wheel air valve 2. Figure 4 The position indicated by the green part is the position for adsorbing cigarettes, and a plurality of long grooves for adsorbing cigarettes are arranged on the outside of the rubbing drum 3 .

[0025] After the arc-shaped rejection model assembly 1 is installed, the position is between the rubbing drum wheel air valve 2 and the rubbing drum wheel 3. The specific structure is as follows: Figure 1 shown.

[0026] The arc-shaped rejection model component 1 includes an outer layer component and an inner layer component.

[0027] The outer layer component of the arc-shaped rejection model component 1 is an arc-shaped plate, and the arc corresponds to the inner surface of the splicing drum 3. Five special-shaped protrusions are arranged on the outer arc surface of the arc-shaped plate, and the special-shaped protrusions are relatively close to the inner wall of the splicing drum 3. The five special-shaped protrusions are spaced apart to form six air control ducts 1-4 that are connected to the negative pressure inside the splicing drum 3. The function of the air control ducts 1-4 is to keep the negative pressure air volume before and after the arc-shaped rejection die head balanced.

[0028] Each of the special-shaped protrusions is provided with air holes and rounded air collecting concave circles 1-3, and the air holes on the five special-shaped protrusions correspond to a group of holes on the rubbing drum 3, that is, Figure 4 As shown in the red box. The lower part of the wind hole of each special-shaped protrusion corresponds to a rounded wind collecting concave circle 1-3 that is not connected to the wind hole, and the rounded wind collecting concave circle 1-3 is arranged along the circumferential direction of the rubbing drum 3. Preferably, the special-shaped protrusion is provided with a wind hole in the middle, and the lower part is a rounded wind collecting concave circle 1-3. The width of the rounded wind collecting concave circle 1-3 corresponds to the diameter of the upper wind hole. The rounded wind collecting concave circle 1-3 extends along the circumferential direction of the rubbing drum 3 to the edge of the special-shaped protrusion, so that the rounded wind collecting concave circle 1-3 is connected with the negative pressure inside the rubbing drum 3. The function of the rounded wind collecting concave circle 1-3 is to reduce the negative pressure in the area when rejecting, and to maintain a certain negative pressure when no rejection is needed to absorb and transfer cigarettes. Preferably, the top of the special-shaped protrusion is rounded and a certain distance is left between it and the wind hole. This is to reduce the negative pressure before rejection so that the rejected cigarettes will not be dragged.

[0029] Specifically, Figure 1 As shown, five special-shaped bumps are arranged symmetrically on the left and right, namely special-shaped bump I1-1-1, special-shaped bump II1-1-2, special-shaped bump III1-1-3, special-shaped bump II1-1-2, and special-shaped bump I1-1-1.

[0030] The air hole on the special-shaped protrusion I1-1-1 is a large hole 1-2-1, and the large hole 1-2-1 corresponds to the cigarette suction hole on the rubbing drum wheel 3. There are two types of air holes on the special-shaped protrusion II1-1-2. The one close to the special-shaped protrusion I1-1-1 is a small hole 1-2-2 with three holes in a vertical row, and the small holes 1-2-2 correspond to the cork paper suction holes on the rubbing drum wheel 3; the one close to the special-shaped protrusion III1-1-3 is a medium hole 1-2-3, and the medium hole 1-2-3 corresponds to the filter suction hole on the rubbing drum wheel 3. There are two rounded corner wind collection concave circles 1-3 on the special-shaped protrusion II1-1-2, one corresponding to the small hole 1-2-2, and the other corresponding to the medium hole 1-2-3. The air hole on the special-shaped protrusion III1-1-3 is a medium hole 1-2-3, which corresponds to the filter suction hole on the rubbing drum wheel 3. Different air holes are controlled by independent solenoid valves to control the on and off of air supply, so that they can be removed individually or all at once.

[0031] The inner component of the arc-shaped rejection model component 1 is provided with an air duct communicating with the air hole, the air duct is connected to the air storage tank through the air duct, and is controlled on and off by a solenoid valve. Preferably, the solenoid valve is controlled by a PLC controller.

[0032] When used specifically:

[0033] After the equipment is started, since the first few groups of cigarettes, filter segments, tipping papers, etc. are different in the collection process, the PLC sets the program time to reject the cigarettes in the first few groups. That is, during the time of the several groups of cigarettes that need to be rejected, the solenoid valve is turned on to supply air to the air holes of the arc-shaped rejection model component 1 to ensure that the cigarettes and auxiliary materials entering the splicing process fully meet the splicing requirements, thereby avoiding the occurrence of clogging of the washboard.

[0034] The raised special-shaped bumps on the working surface of the arc-shaped rejection die head are relatively closed to the inner wall of the splicing drum wheel, ensuring that the compressed air will not leak to the surroundings during rejection, and directly enter five groups of air holes with different apertures to ensure the accuracy of rejection. The compressed air required for rejection is only provided when the equipment is started and stopped, and the on-off time is set by the PLC parameters. There are six air control ducts on the working surface of the arc-shaped rejection die head, which is used to connect the vacuum negative pressure before and after the rejection die head and balance the adsorption negative pressure. The convex area at the front end of the special-shaped bump is used to reduce the vacuum negative pressure before rejection, so that there is no dragging phenomenon when rejecting cigarettes. When rejection is not required, there is no need to remove the arc-shaped rejection model assembly, just close the solenoid valve on the corresponding air hole air supply pipeline. During normal production and operation of the equipment, the rejection die head can complete the corresponding rejection of tipping paper joints and filterless cigarettes under PLC control, avoiding the two situations where cigarettes enter the scrubbing board and cause blockage in the splicing process. When the machine is stopped, the rejection device in front of the washboard sends a stop signal, and all the incomplete cigarettes are rejected when passing through the arc-shaped rejection die head, so that the remaining cigarettes cannot enter between the cigarette rubbing drum and the washboard, clearing the channel for the next cycle of the equipment. This structure can achieve two functions: transferring cigarettes as needed and rejecting residual cigarettes as needed.
