Description

Technical Field

[0001] This utility model belongs to the field of cardboard box production technology, specifically relating to a cigarette cardboard box forming machine. Background Technology

[0002] In the tobacco packaging production industry, cigarette carton forming machines play a crucial role in the forming and processing of cartons. Currently, the common working mode of cigarette carton forming machines on the market is as follows: first, suction cups are used to pick up the cut cardboard, then two sets of cylinders below are used to fold the bottom of the cardboard. After folding, the suction cups push the folded carton into the track, and finally, the bottom tape is applied.

[0003] However, this traditional cigarette carton forming machine has many obvious drawbacks. Firstly, its working efficiency is low. During the folding process of the two sets of cylinders on the bottom plate, the entire machine needs to pause and wait. This pause significantly affects the production rhythm, prolonging the forming time of a single carton and making it difficult to meet the ever-increasing demand for tobacco packaging. Secondly, the tape adhesion effect is unsatisfactory. After being glued by this forming machine, gaps often appear between the bottom cardboard and the carton body, making a tight bond impossible. This not only affects the overall appearance quality of the carton and reduces the visual appeal of the product, but also weakens the carton's sealing and stability. During subsequent transportation and storage of tobacco products, this can easily lead to damage to the carton and the tobacco products, causing unnecessary economic losses for the company.

[0004] In conclusion, the existing cigarette carton forming machines have shortcomings in efficiency and bonding quality, and there is an urgent need for a new technical solution to improve them in order to enhance the overall level of tobacco packaging production. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0034] In one embodiment of this utility model, such as Figure 1-4 As shown, a cigarette carton forming machine is provided, including a support 10, a storage rack 20, an adsorption device 30, a push rod 40, a forming device 50, a conveying device 60, a fixing component 70, and an adhesive tape applicator 80.

[0035] The support 10 is a frame structure used to fix and support the components in the forming machine. A storage rack 20 for storing cartons to be formed is provided in front of the support 10. An adsorption device 30, movable forward, backward, left, and right, is fixed on the support 10 to grasp and move the cartons. Push rods 40 and forming devices 50 are located on both sides of the adsorption device 30. The movement of the folded cartons by the adsorption device 30, in conjunction with the push rods 40 and the forming device 50, causes the folded cartons to open. A conveying device 60 is located behind the forming device 50. During the conveying process, the forming device 50 completes the forming of the cartons. Subsequently, the conveying device 60 fixes the cartons on both sides while moving them to the finished product outlet of the forming machine.

The fixing component 70 cooperates with the conveying device 60 to fix the box body in the vertical direction, so that the box body can move while being tightly fixed. A tape applying mechanism 80 is provided below the conveying device 60. When the tape applying mechanism 80 applies tape to the tightly fixed box body, the cardboard at the bottom of the box body is in close contact with the box body. At the same time, the fixing component 70 applies a downward force to the box body to make the bottom of the box body in close contact with the tape. Through the above-mentioned components, the forming cycle of a single cigarette carton is shortened, the production rhythm is more compact, and the production efficiency is improved. At the same time, it ensures that the tape is tightly attached to the box body, avoids the formation of gaps, and significantly improves the sealing and stability of the bottom of the carton.

[0036] The bracket 10 is provided with a housing 11, and a groove 12 is provided in the middle of the housing 11. The housing 11 is used to fix and support the forming device 50, the conveying device 60, and the tape applying mechanism 80.

[0037] The storage rack 20 is provided with a baffle 21 and a limiting plate 22. The baffle 21 is movably disposed in front of the storage rack 20. The baffle 21 and the limiting plate 22 cooperate to limit the cardboard to be formed on the storage rack 20. There are multiple limiting plates 22, which are disposed behind the storage rack 20. They cooperate with the storage rack 20 to restrict the cardboard to be formed within the storage rack 20. The limiting plate 22 is made of an elastic and easily deformable material. When the adsorption device 30 adsorbs the cardboard to be formed and moves the cardboard backward, the limiting plate 22 is pushed by the cardboard to deform, causing the cardboard adsorbed by the adsorption device 30 to detach from the storage rack 20. Then it immediately resets and limits the remaining cardboard on the storage rack 20.

[0038] The adsorption device 30 consists of a transverse drive track 31, a longitudinal drive track 32, and a suction cup 33. The transverse drive track 31 is fixedly mounted on the right side of the bracket 10. The longitudinal drive track 32 is mounted on the transverse drive track 31, and the suction cup 33 is mounted on the longitudinal drive track 32. The transverse drive track 31 drives the longitudinal drive track 32 to move the suction cup 33 back and forth, so that the suction cup 33 adsorbs the cardboard box to be formed and moves the cardboard box back and forth, thereby aligning the cardboard box with the transmission channel in the transmission device 60. The longitudinal drive track 32 can drive the suction cup 33 to move left and right, thereby moving the cardboard box aligned with the transmission channel in the transmission device 60 into the transmission device 60.

[0039] One end of the push rod 40 is fixed to the bracket 10, and the other end is located behind the storage rack 20. The end of the push rod 40 fixed to the bracket 10 is a straight cylinder, and the end near the storage rack 20 is an arc-shaped cylinder with the bending direction facing the right side of the storage rack 20. The push rod 40 is designed so that when the adsorption device 30 adsorbs the front of the carton and moves the carton backward, the push rod 40 pushes the right side of the carton so that the right side of the carton is perpendicular to the front of the carton, and at the same time moves the back of the carton to be parallel to the front of the carton, thereby changing the carton from a folded state to a square state.

[0040] The forming device 50 consists of a guide plate 51, a telescopic cylinder 52, a limiting block 53, an auxiliary plate 54, and a movable plate 55.

[0041] The guide plate 51 is fixedly disposed in the groove 12 of the bracket 10. The guide plate 51 is arc-shaped, and the apex of the guide plate 51 is lower than the bottom surface of the conveying device 60 in the groove 12. The guide plate 51 serves to push the bottom left wing of the carton entering the groove 12 to fold to the predetermined position after the carton is formed. A telescopic cylinder 52 fixed to the bracket 10 is provided on the right side of the guide plate 51. After the carton enters the groove 12, the bottom left wing of the carton is folded to the predetermined position after the carton is formed by the guide plate 51, and then the telescopic cylinder 52 pushes the bottom right wing of the carton to fold to the predetermined position after the carton is formed.

[0042] A limiting block 53 is provided on the left side of the guide plate 51. One end of the limiting block 53 is fixedly connected to the guide plate 51, and the other end is connected to the auxiliary plate 54. The limiting block 53 serves to keep the left and right wings of the bottom of the folded carton in the folding direction. The auxiliary plate 54 is inclined, with one end connected to the limiting block 53 and the other end connected to the conveying device 60. The auxiliary plate 54 serves to transfer the folded carton into the conveying device 60.

[0043] Movable plates 55 are provided on both sides of the groove 12 at positions corresponding to the limiting blocks 53. The upper parts of both sides of the movable plates 55 are movably connected to the side walls of the groove 12. A driving device, such as a telescopic cylinder, is provided behind the movable plates 55 to drive the movable plates 55 to perform upward opening and closing movements. When the left and right wings of the bottom of the carton are folded, the front and rear ends of the bottom of the carton move to the corresponding positions of the movable plates 55, and the movable plates 55 move upward to push the front and rear ends of the bottom of the carton to fold.

[0044] The transmission device 60 consists of a bottom roller conveyor plate 61, a conveyor belt 62, a side roller conveyor plate 63, and a top roller conveyor plate 64.

[0045] The bottom roller conveyor plate 61 is fixedly disposed in the groove 12, and the top surface of the bottom roller conveyor plate 61 is lower than the top surface of the groove 12 but higher than the top surface of the guide plate 51. The bottom roller conveyor plate 61 is provided with movable holes for the tape applicator 80 to extend and move left and right. Multiple rollers are evenly provided on the bottom roller conveyor plate 61 to reduce the friction between the carton and the conveying device 60.

[0046] The conveyor belt 62 is fixedly mounted on the housing 11 and located on both sides of the groove 12. The conveyor belt 62 serves to transport the carton from the inlet of the forming machine to the outlet.

[0047] A side roller conveyor plate 63 is fixedly provided on the upper inner side of the conveyor belt 62, and a top roller conveyor plate 64 is movably provided on the upper side of the side roller conveyor plate 63. The top roller conveyor plate 64 has reserved holes on both sides corresponding to the side roller conveyor plate 63, so that the top roller conveyor plate 64 can be sleeved on the side roller conveyor plate 63 and can move up and down along the side roller conveyor plate 63.

[0048] A fixing component 70 is fixedly provided above the top roller conveyor plate 64, such as... Figure 5 As shown, the fixing component 70 consists of a connecting rod 71, a telescopic rod 72, and a spring 73.

[0049] One end of the connecting rod 71 is fixed to the bracket 10, and the other end is fixedly connected to the telescopic rod 72. The other end of the telescopic rod 72 is fixed to the top surface of the top roller conveyor plate 64. The telescopic rod 72 is composed of an inner tube and an outer tube, and a spring 73 is provided at the bottom of the inner tube. One end of the spring 73 is connected to the bottom of the inner tube, and the other end is connected to the top surface of the top roller conveyor plate 64. The spring 73 is confined in the telescopic rod 72. The spring 73 applies pressure to the top roller conveyor plate 64, keeping the telescopic rod 72 in an extended state. When a carton passes under the top roller conveyor plate 64, after the carton passes the auxiliary plate 54, the carton pushes up the top roller conveyor plate 64, causing the spring 73 to contract. At the same time, the spring 73 applies pressure to the top roller conveyor plate 64, thereby causing the carton to receive pressure.

[0050] The working principle of this utility model is as follows: A cigarette carton forming machine, in use, places the carton to be formed on the storage rack 20, and the horizontal drive rail 31 drives the suction cup 33 to move forward to adsorb the front of the carton. Then, the suction cup 33 is controlled to move backward to the position corresponding to the groove 12. During this process, the side of the carton contacts the curved part of the push rod 40. As the suction cup 33 moves backward, the side of the carton is pushed by the push rod 40, and the angle between the side and the front of the carton continuously decreases until the carton is located on the straight part of the push rod 40, at which point the angle between the side and the front of the carton is 90 degrees. Next, the longitudinal drive track 32 moves the carton to the left until it enters the groove 12. The left wing of the bottom of the carton is folded by the guide plate 51. Then, the main body of the carton enters the space between the conveyor belts 62. As the conveyor belts 62 move the carton towards the exit, the telescopic cylinder 52 pushes the right wing of the bottom of the carton to fold. Then, the left and right wings of the carton are restricted in direction by the limiting block 53. After the carton moves directly above the limiting block 53, the movable plate 55 moves upward, folding the front and rear ends of the bottom of the carton. Then, the conveyor belt 6... 2. The carton is driven past the auxiliary plate 54, and the height of the carton in the groove 12 rises. At the same time, the left and right wings and the front and rear ends of the bottom of the carton are at a 90-degree angle to the main body of the carton. The carton lifts the top roller conveyor plate 64, the spring 73 contracts, and the top roller conveyor plate 64 cooperates with the bottom roller plate 61 to make the bottom of the carton in close contact with the tape applicator 80. Then, the carton moves continuously towards the exit under the conveyor belt 62. At the same time, the tape applicator 80 completes the applicator work on the bottom of the carton.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
