Description

Technical Field

[0001] This utility model relates to the field of inner lining paper cutting technology, and in particular to a multi-group inner lining paper cutting and positioning device. Background Technology

[0002] In automated packaging production lines, inner liner paper is typically unwound in rolls and then cut into individual sheets of fixed length after being conveyed by a traction conveyor. To ensure accurate cutting dimensions, pattern alignment, and neat edges, the inner liner paper must be precisely positioned before cutting.

[0003] When moving the inner liner paper to the cutting area, existing methods using belt conveyors are prone to slippage, resulting in inaccurate positioning of the inner liner paper. Using roller conveyors may result in uneven pressure, causing damage to the surface of the cigarette inner liner paper. This uneven pressure may also cause damage to thinner paper. Using grippers for traction can easily cause indentations, affecting the appearance of the inner liner paper.

[0004] During overall vacuum adsorption positioning, a vacuum platform is set up below the cutting station. Negative pressure is used to adsorb the inner liner paper onto a flat surface to prevent cutting vibration. This method can effectively fix the paper, but it has the following problems: using an integral vacuum chamber, the adsorption area is uncontrollable, and it is impossible to position the cut inner liner paper pieces in sections. This results in uneven areas of the paper that cannot be flattened during cutting. The paper is prone to wrinkles or local suspension during adsorption due to uneven airflow or inconsistent initial tension. There is a lack of active flattening mechanism, especially for ultra-thin and easily deformable materials such as aluminum foil, where flatness is difficult to guarantee. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-set inner lining paper cutting and positioning device to solve the technical problems mentioned in the background art, such as the easy damage to the surface of the inner lining paper during transfer and the inability of the inner lining paper to be effectively flattened.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-set inner lining paper cutting and positioning device, including a worktable, a plurality of adsorption chambers are provided in the worktable, the tops of the plurality of adsorption chambers are all connected to the outside through a connecting groove, a fixed frame is fixedly provided on the worktable, a movable frame is slidably provided on the fixed frame, two connecting frames are fixedly provided at the end of the movable frame near the connecting groove, each connecting frame is provided with an adsorption element that can move up and down at the end of the connecting frame near the connecting groove, a movable roller that can move up and down is provided at the end of the connecting frame near the connecting groove, and a cutter that can move up and down is provided at the end of the fixed frame near the connecting groove.

[0007] Preferably, the bottom of the workbench is provided with a plurality of solenoid valves connected to the corresponding adsorption chambers.

[0008] Preferably, two guide rails are fixedly provided inside the fixed frame, and the movable frame is slidably connected to the two guide rails.

[0009] Preferably, each of the connecting frames is fixedly provided with two automatic telescopic columns at its bottom, and each of the adsorption components is fixedly connected to the telescopic ends of the corresponding two automatic telescopic columns.

[0010] Preferably, each of the connecting frames has a sliding rod on both sides, and two sliding rods on the same connecting frame are provided with a rotating shaft that rotates together. Each rotating shaft is fixedly connected to the corresponding sliding roller, and an elastic element is provided between the top of each sliding rod and the corresponding connecting frame.

[0011] Preferably, an electric telescopic column is fixedly provided at the bottom of the fixing frame, and the telescopic end of the electric telescopic column is fixedly connected to the cutter.

[0012] Preferably, multiple workbenches and mounting frames can be arranged side by side.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using two adsorption components and multiple adsorption chambers, the inner lining paper can be adsorbed and fixed during cutting. Simultaneous compression by the adsorption components and moving rollers, combined with adsorption through the adsorption chambers and connecting grooves, prevents the inner lining paper from being torn on one side due to pressure from a single fixing component. The three different adsorption chambers operate at different times, accommodating the positioning needs of inner lining paper of varying lengths. This avoids the limitation of a single chamber being unable to accommodate different lengths. Furthermore, it allows for segmented positioning, unfolding a portion before adsorbing and positioning another, thus preventing material waste caused by unevenness in the middle section leading to substandard cut inner lining paper.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] In automated packaging production lines, inner liner paper is typically unwound in rolls and then cut into individual sheets of fixed length after being conveyed by a traction conveyor. To ensure accurate cutting dimensions, pattern alignment, and neat edges, the inner liner paper must be precisely positioned before cutting.

[0025] When moving the inner liner paper to the cutting area, existing methods using belt conveyors are prone to slippage, resulting in inaccurate positioning of the inner liner paper. Using roller conveyors may result in uneven pressure, causing damage to the surface of the cigarette inner liner paper. This uneven pressure may also cause damage to thinner paper. Using grippers for traction can easily cause indentations, affecting the appearance of the inner liner paper.

[0026] To resolve the above technical issues, please refer to Figures 1 to 6As shown, an embodiment of the present invention provides a multi-group inner lining paper cutting and positioning device, including a workbench 1. The workbench 1 has adsorption chambers 101, the tops of which are connected to the outside via connecting grooves 102. A fixed frame 2 is fixedly mounted on the workbench 1, and a movable frame 201 is slidably mounted on the fixed frame 2. Two connecting frames 203 are fixedly mounted on the end of the movable frame 201 near the connecting groove 102. Each connecting frame 203 has an adsorption element 204 that can move up and down near the end of the connecting groove 102. Multiple adsorption grooves 2041 are formed at the bottom of the adsorption element 204. A movable roller 205 that can move up and down is provided on the end of the connecting frame 203 near the connecting groove 102. A cutter 206 that can move up and down is provided on the end of the fixed frame 2 near the connecting groove 102. Multiple solenoid valves 103 connected to the corresponding adsorption chambers 101 are located at the bottom of the workbench 1. The fixed frame 2 is fixed with... The device is equipped with two guide rails 207, and the movable frame 201 is slidably connected to the two guide rails 207. Each connecting frame 203 has two automatic telescopic columns 208 fixedly installed at its bottom. Each adsorption component 204 is fixedly connected to the telescopic end of the corresponding two automatic telescopic columns 208. Each connecting frame 203 has a sliding rod 210 on both sides. The two moving rods 210 on the same connecting frame 203 are connected to a rotating shaft 211. Each rotating shaft 211 is fixedly connected to the corresponding moving roller 205. Each moving rod 210 has an elastic element 212 between its top and the corresponding connecting frame 203. The fixed frame 2 has an electric telescopic column 209 fixedly installed at its bottom. The telescopic end of the electric telescopic column 209 is fixedly connected to the cutter 206. This device can be equipped with multiple worktables 1 and fixed frames 2, as well as auxiliary structures on the worktables 1 and fixed frames 2, so that multiple sets of inner lining paper can be simultaneously positioned and cut.

[0027] In use, the workbench 1 is first installed on the corresponding equipment, and the electric telescopic column 209 and the automatic telescopic column 208 are electrically connected to the controller of the corresponding equipment. The controller of the equipment is not shown in the figure. A lead screw is rotatably provided on the fixed frame 2. The lead screw is threadedly connected to the moving frame 201. The lead screw is driven by a motor (not shown in the figure). The motor is electrically connected to the controller of the equipment. The adsorption chamber 101 is connected to the external air supply equipment (not shown in the figure) through the solenoid valve 103. The adsorption component 204 is connected to the external air supply equipment. The external air supply equipment is electrically connected to the controller. The above technology is existing technology and will not be described in detail here.

[0028] After installation, when cutting the inner lining paper, the adsorption element 204 near the cutter 206 first adsorbs the inner lining paper from the position conveyed in the previous process through the adsorption groove 2041. The controller controls the air supply equipment to put the adsorption element 204 in a negative pressure state, so that the adsorption element 204 adsorbs the end of the inner lining paper that protrudes through the adsorption groove 2041. The adsorption element 204 on the other side repeats the above negative pressure state to adsorb the already cut inner lining paper. At the same time, the controller controls the electric telescopic column 209 to retract and the cutter 206 to move upward.

[0029] After the two adsorption elements 204 adsorb the corresponding inner lining paper, the automatic telescopic column 208 retracts. The electric telescopic column 209, the automatic telescopic column 208, and their connection with the controller are all existing technologies and will not be described in detail here. This causes the adsorption element 204 to move slightly upward, thereby preventing the edge of the inner lining paper from colliding and deforming with the workbench 1 and the receiving point of the next process when the inner lining paper is transferred. Then, the controller starts the motor, which drives the moving frame 201 to move away from the cutter 206 through the lead screw. The moving frame 201 moves on the fixed frame 2 through the guide rail 207. At the same time, the moving frame 201 drives the adsorption element 204 to move in the same direction through the connecting frame 203. The connection between the motor and the controller and the setting of the lead screw are all existing technologies and will not be described in detail here. The adsorption element 204 pulls the inner lining paper to move away from the cutter 206.

[0030] The distance the adsorption element 204 moves can be detected by adding a displacement sensor. After the adsorption element 204 moves a certain distance, the motor stops running. Then the controller controls the automatic telescopic column 208 to extend, so that the adsorption element 204 drives the end of the inner lining paper that is adsorbed to contact the top end face of the workbench 1. Then the controller starts the external air supply equipment. The air supply equipment evacuates the adsorption chamber 101 through the solenoid valve 103, so that the adsorption chamber 101 is in a negative pressure state. At the same time, the negative pressure state of the two adsorption elements 204 is released by controlling the external air supply equipment. Then the electric telescopic column 209 extends and drives the cutter 206 to move down. The cutter 206 passes through the corresponding connecting frame 203 and cuts the inner lining paper. The adsorption element 204 on the other side sends the cut inner lining paper to the next process for processing.

[0031] After cutting, the two adsorption components 204 move upward under the action of the corresponding automatic telescopic column 208, and the motor drives the lead screw to rotate, so that the adsorption components 204 move back to the corresponding initial position. During this process, the connecting frame 203 drives the moving roller 205 to squeeze the inner lining paper through the elastic component 212 and flatten the inner lining paper to avoid unevenness of the adsorbed part of the inner lining paper, which would cause uneven cutting edges during subsequent cutting.

[0032] As the moving roller 205 moves, the moving roller 205 away from the cutter 206 squeezes the end of the uncut inner lining paper away from the cutter 206, while the moving roller 205 close to the cutter 206 is located between the cutter 206 and the input end of the inner lining paper and squeezes that point. This prevents uneven cutting caused by the stretching of both ends of the inner lining paper at the cut point when the cutter 206 is cutting. The suction member 204 close to the cutter 206 picks up the uncut inner lining paper, and the suction member 204 away from the cutter 206 picks up the cut inner lining paper. The corresponding inner lining paper is transferred to the corresponding position according to the above operation mode. Continuous operation can be performed to carry out continuous cutting. This device can be equipped with multiple worktables 1 and fixed frames 2, as well as auxiliary structures on the worktables 1 and fixed frames 2, so that multiple sets of inner lining paper can be simultaneously positioned and cut.

[0033] By using two adsorption elements 204 and multiple adsorption cavities 101, the inner lining paper can be adsorbed and fixed during cutting. At the same time, the adsorption elements 204 and the moving roller 205 squeeze and adsorb the paper using the adsorption cavities 101 and the connecting groove 102, so that when the cutter 206 is cutting, the inner lining paper is not squeezed by a single fixed component, which would cause the fixed side of the inner lining paper to be torn.

[0034] Example 2

[0035] In practical use, it was found that the overall vacuum adsorption positioning, with a vacuum platform set below the cutting station, uses negative pressure to adsorb the inner liner paper onto a flat surface to prevent cutting vibration. This method can effectively fix the paper, but it has the following problems: the use of an integral vacuum chamber makes the adsorption area uncontrollable, and it cannot position the cut inner liner paper pieces in sections. This results in uneven areas in the middle of the paper during cutting that cannot be effectively flattened by the moving roller 205. During the adsorption process, the paper is prone to wrinkles or local suspension due to uneven airflow or inconsistent initial tension. When the moving roller 205 flattens the inner liner paper, the wrinkled or locally suspended parts are squeezed and deformed, especially for ultra-thin and easily deformable materials such as aluminum foil, making it difficult to guarantee flatness.

[0036] Based on the above embodiments, in order to solve the above technical problems, please refer to... Figures 1 to 6 As shown, the technical solution adopted includes a workbench 1, which has multiple adsorption chambers 101. The tops of the multiple adsorption chambers 101 are connected to the outside through a connecting groove 102. The adsorption chambers 101 are divided into a front negative pressure chamber 1011, a middle negative pressure chamber 1012 and a rear negative pressure chamber 1013. A solenoid valve 103 is provided at the bottom of the adsorption chambers 101. This device can be equipped with multiple workbenches 1 and fixed frames 2 as well as auxiliary structures on the workbenches 1 and fixed frames 2, so that this device can perform simultaneous positioning and cutting operations on multiple sets of inner lining paper.

[0037] Based on the above embodiments, during use, after the adsorption member 204 moves the inner liner paper to a corresponding position away from the cutter 206, and the adsorption member 204 is pressed down by the automatic telescopic column 208, the front negative pressure chamber 1011 begins to adsorb the leftmost part of the inner liner paper under the control of the air supply device controlled by the controller. That is, the side away from the cutter 206 is the front negative pressure chamber 1011, and the adsorption member 204 moves upward after the automatic telescopic column 208 extends.

[0038] Subsequently, the motor drives the moving frame 201 to move towards the cutter 206 via the lead screw. At this time, the moving roller 205 squeezes the inner liner paper under the action of the elastic element 212. When the moving roller 205 moves to the position of the front negative pressure chamber 1011 and continues to move, the front negative pressure chamber 1011 changes to a negative pressure state under the control of the air supply device. At this time, the middle negative pressure chamber 1012 and the rear negative pressure chamber 1013 can be adjusted to a blowing state, thereby preventing the middle and tail of the inner liner paper from being gradually flattened by the moving roller 205.

[0039] When the moving roller 205 moves to the position of the middle negative pressure chamber 1012, the middle negative pressure chamber 1012 is switched to a negative pressure state under the control of the air supply equipment controlled by the controller, and the rear negative pressure chamber 1013 is in a blowing state, achieving a state of simultaneous squeezing and adsorption, which is conducive to the better flattening of the inner lining paper, thereby preventing the middle and tail of the inner lining paper from being gradually flattened by the moving roller 205. Subsequently, after the moving roller 205 moves to the position of the rear negative pressure chamber 1013, the rear negative pressure chamber 1013 is switched to a negative pressure state. The position of the moving roller 205 can be detected by adding a corresponding displacement sensor and transmitted to the controller, and then the controller makes corresponding adjustments. This technology is existing technology and will not be described in detail here.

[0040] When the two moving rollers 205 move to the initial position, the motor stops working under the action of the controller, and the two automatic telescopic columns 208 extend, causing the adsorption element 204 to move down and squeeze the inner lining paper. Then the cutting work can begin. During this process, when the length of the inner lining paper to be cut is short, the adjacent front negative pressure chamber 1011 and middle negative pressure chamber 1012 can also be controlled to adsorb the shorter inner lining paper. It can be adapted to the positioning requirements of inner lining paper of different lengths. Moreover, segmented adsorption can prevent the inner lining paper from being adsorbed before it can be fully spread out during single adsorption, resulting in wrinkles in the middle part, which would cause the processed inner lining paper to not meet the quality requirements and waste raw materials. This device can be equipped with multiple worktables 1 and fixed frames 2 and auxiliary structures on the worktables 1 and fixed frames 2, so that this device can perform simultaneous positioning and cutting operations on multiple sets of inner lining paper.

[0041] By having three different adsorption chambers 101 working at different times, it can be adapted to the positioning needs of inner lining paper of different lengths, avoiding the inability of a single chamber to position inner lining paper of different lengths. It can also be positioned in sections, unfolding a part and then adsorbing and positioning another part, thus preventing the waste of raw materials caused by unevenness in the middle section, which would result in the cut inner lining paper not meeting the requirements.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
