Description

Technical Field

[0001] The present invention relates to the technical field of automatic cigarette packaging equipment, and specifically to the improvement of a high-speed cigarette transfer and aluminum foil packaging device for transferring cigarettes conveyed from a mold box belt to a second wheel to prepare for aluminum foil packaging. Background Art

[0002] The cigarette conveying wheel is commonly called the first wheel or the No. 1 wheel in the industry. The first wheel is located in the head of the GD main machine, between the cigarette mold box belt and the second wheel. It performs the first molding of cigarettes and is the beginning of packaging molding. If there are quality defects in the first wheel, it will cause material waste in all subsequent steps. Therefore, once the first wheel fails, it will cause great economic losses.

[0003] The existing wheel is mainly composed of a wheel body, a left claw mechanism and a right claw mechanism, a cigarette holder mold box and a reset spring. The left claw mechanism and the right claw mechanism are driven to close by a cam, and the spring is pulled between the left and right claw arms to reset the claw arms to the open state.

[0004] The function and working principle of the first wheel: Its function is to transfer the arranged cigarettes conveyed by the belt from the mold box to the second wheel, preparing them for aluminum foil packaging.

[0005] When the arranged cigarettes stop in front of the first wheel, the first wheel is in a horizontal position, and its left and right claws are both in a slightly open horizontal state. Then the push plate pushes the cigarettes into the mold box of the first wheel, and then the left and right teams of claws are tightened to prevent the cigarettes from shifting during the rotation of the first wheel. Then the first wheel rotates counterclockwise, rotates 90 degrees twice, and turns the cigarettes to the horizontal position on the left end, aligning them with the mold box on the right side of the second wheel in a horizontal position. After the aluminum foil is in place, the push plate pushes the cigarettes into the mold box of the second wheel.

[0006] A coupling extends from the main box at the first wheel and is connected to the center shaft of the first wheel. When the gear of the main box rotates, the first wheel rotates with it. A cam is fixed on the top of the center shaft, and the center shaft transmits the movement to the cam through the clamping mechanism. The surface of the cam contacts the driven wheels on the long and short swing arms. When the cam rotates, it can push the swing arm to rotate around the axis. The left and right claws are clamped on the long and short swing arm shafts with screws. When the swing arm shaft swings, the claws swing with it, and finally realize the opening and closing movement of the claws. Among them, because the original first wheel uses an external cam, the swing arm cannot be reset, and the reset spring plays the role of providing preload and reset for the swing arm.

[0007] The existing round has the following technical problems:

[0008] 1. Insufficient sealing protection. The existing first wheel is a semi-open structure, with only the cam and four swing arm rollers in the box, and other components are outside the box and lubricated with grease. There is a lot of smoke and dust at the first wheel, and grease is easily contaminated by smoke and dust. In a semi-open structure, smoke and dust can easily enter the gap between the parts, causing the connection to gradually wear out, causing the connection to fail or lock, and ultimately causing inaccurate movement of the first wheel.

[0009] 2. Large space occupied. In the existing one-wheel, the left and right claws are located in front of the cam, resulting in the entire one-wheel structure occupying a large space.

[0010] 3. Poor spring reset stability. The existing one-wheel uses an external cam to push the swing arm to retract and close the left claw mechanism and the right claw mechanism, and uses a reset spring to pull the swing arm to open the left claw mechanism and the right claw mechanism. Since the spring is a flexible part, it is easy to generate impact load when it switches quickly between compression and opening, especially in high-speed movement, this impact is particularly significant.

[0011] 4. Low transmission efficiency. The left and right clamps in the existing wheel are symmetrically arranged, and need to rotate 180 degrees to receive and transmit cigarettes, resulting in low transmission efficiency.

[0012] 5. The lift return curve of the existing cam is very short, with sharp corners and very drastic changes. The non-smooth cam surface curve will cause rigid impact of the cam follower, which directly affects the service life of the follower roller. The original cam follower roller has a small diameter and limited bearing capacity. Under a large impact force, it is very easy to cause damage to the cam follower roller.

[0013] Therefore, there are many defects in the structure and material selection of the first round, resulting in a high failure rate. The failure of the first round mainly affects the quality of the cigarettes. In the subsequent packaging process of the first round, there is no device to automatically detect the quality of the cigarettes. Therefore, once the first round of packaging fails, it will not only lead to a serious waste of production materials, but also cause a huge waste of manpower and material resources. Summary of the invention

A cam driving mechanism 30 for driving each clamping claw mechanism to open and close is provided in the cavity, and the cam driving mechanism 30 includes four coaxially rotating cams 31; the clamping claw mechanism 22 also includes a first connecting shaft 225 and a second connecting shaft 226 in the cavity, and the two ends of the first connecting shaft 225 pass through the two sealing covers and are respectively connected to the first upper claw arm and the second upper claw arm, and the first connecting shaft 225 is provided with two first swing arms 2251 for clamping on both sides of the cam, and each first swing arm 2251 is provided with a first swing arm 2252, and each first swing arm 2252 is provided with a first swing arm 2253, and each first swing arm 2254 is provided with a first swing arm 2255, and each first swing arm 2256 is provided with a first swing arm 2256, and each first swing arm 2256 is provided with a first swing arm 2251 for clamping on both sides of the cam, and each first swing arm 2252 is provided with a first swing arm 2253, and each first swing arm 2254 is provided with a first swing arm 2255, and each first swing arm 2252 ... A first through slot 22511 is provided in one swing arm for the edge of the cam to extend into, and a first roller 22512 is provided at the end of the first through slot for keeping in contact with the cam surface; two ends of the second connecting shaft 226 pass through two sealing covers and are respectively connected to the first lower claw arm and the second lower claw arm, and the second connecting shaft is provided with two second swing arms 2261 for clamping on both sides of the cam, and each second swing arm is provided with a second through slot 22611 for the cam to extend into, and a second roller 22612 is provided at the end of the second through slot for keeping in contact with the cam surface, so that when assembling When the cam driving mechanism 30 is sealed in the cavity 101 of the main housing 10, and the cam driving mechanism 30 is between the first claw arm pair and the second claw arm pair, the occupied space is reduced, and the sealing performance is enhanced; at the same time, the swing arms of each connecting claw arm are clamped on both sides of the cam, and the edge of the cam extends into the through groove of each swing arm to prevent the swing arm from being separated from the cam during the rotation of the main housing 10. The roller on the swing arm keeps in contact with the cam surface, and the rotation of the main housing 10 drives the first connecting shaft 225 and the second connecting shaft 226 to rotate around the cam, so that the claw arms on the connecting shafts open and close. The main housing 10 is connected to the external driving mechanism through the flange connection seat 11. The external driving mechanism can drive the main housing 10 to rotate through the flange connection seat 11, and the main housing 10 drives the first connecting shaft 225 and the second connecting shaft 226 in the clamping claw mechanism 22 to rotate around the cam.

[0034] The swing arms on the first connecting shaft 225 and the second connecting shaft 226 are staggered; the two first swing arms 2251 on the first connecting shaft are respectively clamped on both sides of two of the cams 31, and the two second swing arms 2261 on the second connecting shaft 226 are respectively clamped on both sides of the other two cams 31, so that two swing arms on the two connecting shafts are on one side of the cam as a whole, and the other two swing arms are on the other side of the cam as a whole. The swing arms on the connecting shafts are clamped on both sides of the cam to prevent separation from the cam. At the same time, during the rotation of the main shell 10, the first claw arm and the second claw arm are driven to open and close.

[0035] like Figure 6 As shown, the four cams 31 are the first cam 3101, the second cam 3102, the third cam 3103 and the fourth cam 3104 in order from outside to inside; a first swing arm 2251 on the first connecting shaft 225 is clamped on one side of the first cam 3101 in the cam, and another first swing arm 2251 is clamped on the other side of the third cam 3103 in the cam; a second swing arm on the second connecting shaft 226 is clamped on one side of the second cam 3102 in the cam, and another second swing arm is clamped on the other side of the fourth cam 3104 in the cam, so that each swing arm corresponds to a cam, and the swing arm is clamped on both sides of the cam to prevent the swing arm from separating from the cam during the rotation of the clamping claw mechanism 22 driven by the main housing 10. It is worth noting that the two swing arms on the first connecting shaft and the two cams in the cam form a group of conjugate cams, and the two swing arms on the second connecting shaft and the other two cams in the cam form another group of conjugate cams.

[0036] The cam drive mechanism 30 can be fully lubricated with engine oil in the cavity 101 of the main housing 1. Engine oil lubrication greatly improves the overall motion condition and lubrication effect of the present invention, and can greatly increase the service life of a wheel. The fully enclosed cam drive mechanism 30 no longer has to worry about the technical problem of large smoke and dust, and grease easily getting stained with smoke and dust. There is no need to worry about smoke and dust easily entering the gaps between the parts, causing the connection parts to gradually wear out, causing the connection to fail or lock, and ultimately causing inaccurate movement of a wheel. In order to seal more and prevent the engine oil in the cavity 101 of the main housing 10 from overflowing, both ends of the first connecting shaft 225 and both ends of the second connecting shaft 226 are respectively connected to the sealing cover 12 through bearings and oil seals.

[0037] The main housing 10 is also provided with at least one pair of extension seats 13, each pair of extension seats 13 includes a first extension seat 131 arranged at one end of the main housing and a second extension seat 132 arranged at the other end of the main housing; the mold box 21 includes a first mold box 211 installed on the first extension seat 131 and a second mold box 212 installed on the second extension seat 132, the first mold box 211 is between the first upper claw arm 221 and the first lower claw arm 223, and the second mold box 212 is between the second upper claw arm 222 and the second lower claw arm 224. When the first upper and lower claw arms and the second upper and lower claw arms are opened, the arranged cigarettes conveyed by the belt enter the first mold box 211 and the second mold box 212; when the main housing 10 rotates, due to the closing of the first upper and lower claw arms and the second upper and lower claw arms, the cigarettes will not fall off from the first mold box 211 and the second mold box 212. A cigarette protection claw 2201 with an adjustable connection angle is respectively provided at the end of each claw arm.

[0038] The first mold boxes 211 and the first mold boxes 211 in adjacent cigarette transfer assemblies are connected by a first connecting frame 14, and the second mold boxes 212 and the second mold boxes 212 are connected by a second connecting frame 15, so as to ensure that the first mold boxes 211 and the second mold boxes 212 are firmly installed.

[0039] The first upper claw arm 221 and the second upper claw arm 222 are connected to the two ends of the corresponding first connecting shaft 225 through an axial hole, and the first upper claw arm 221 and the second upper claw arm 222 are both provided with locking bolts. The ends of the first upper claw arm 221 and the second upper claw arm 222 are bent and clamped on the end of the first connecting shaft, and then locked by the locking bolt 227. The first upper claw arm 221 and the second upper claw arm 222 rotate synchronously with the first connecting shaft 225; the first lower claw arm 223 and the second lower claw arm 224 are connected to the two ends of the corresponding second connecting shaft 226 through an axial hole, and the first lower claw arm and the second lower claw arm are both provided with locking bolts. The ends of the first lower claw arm 223 and the second lower claw arm 224 are bent and clamped on the end of the second connecting shaft 226, and then locked by the locking bolt. The first lower claw arm 223 and the second lower claw arm 224 rotate synchronously with the second connecting shaft 226.

[0040] The main shell 10 is provided with four groups of cigarette delivery components 20, and two adjacent groups of cigarette delivery components 20 are at an angle of 90 degrees; thus, a group of arranged cigarettes can be received every 90-degree rotation, thereby improving the delivery efficiency.

[0041] The working process of the cigarette transfer wheel is as follows: 1) the external driving mechanism drives the main shell 10 to rotate, and a group of cigarette transfer components 20 on the main shell 10 rotates to the cigarette receiving station; 2) when the main shell 10 rotates to the cigarette receiving station, the first upper claw arm 221 and the second upper claw arm 222 and the first lower claw arm 223 and the second lower claw arm 224 are driven to open due to the action of the cam, exposing the first mold box 211 and the second mold box 212; 3) the arranged cigarettes conveyed by the belt enter the first mold box 211 and the second mold box 212; 4) under the action of the continued rotation of the main shell 10, the first upper claw arm 221 and the second upper claw arm 222 and the first lower claw arm 223 and the second lower claw arm 224 are driven to close; 5) the external driving mechanism drives the main shell 10 to continue to rotate; the cigarette transfer component loaded with cigarettes rotates to the cigarette conveying station; and another group of cigarette transfer components rotates to the cigarette receiving station.
