Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, and in particular to a feeding device for a corrugated paper die-cutting machine. Background Technology

[0002] A corrugated paper die-cutting machine is a type of machinery specifically designed for processing corrugated cardboard. It can perform precise die-cutting, creasing, and punching processes on corrugated cardboard. Corrugated paper die-cutting machines are widely used in the production of corrugated paper packaging products such as cartons, boxes, and display racks, and are an indispensable piece of equipment in the packaging industry.

[0003] Most corrugated paper die-cutting machines do not have automatic feeding functions during the processing of corrugated cardboard. When the machine is running, the raw materials must be placed one by one in the feed port of the die-cutting machine and fed continuously. Otherwise, the die-cutting machine will stop and affect production efficiency. This method not only consumes a lot of manpower and time, but also reduces the practicality of the machine.

[0004] Therefore, those skilled in the art have provided a feeding device for a corrugated paper die-cutting machine to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a feeding device for a corrugated paper die-cutting machine. The device uses a controller to control a servo motor that drives a reciprocating lead screw. The reciprocating lead screw rotates, causing a slider to reciprocate on the upper end of a slide rail base. Simultaneously, a pusher plate mounted on the upper end of the slider also reciprocates, achieving a reciprocating pushing function. At the same time, a dual-axis motor drives two gears to rotate, causing a toothed plate meshing with the gears to slide up and down within a groove. The up-and-down movement of the toothed plate causes the main body of the support plate and two side plates, located in the middle of its outer wall, to move up and down. During operation, a stack of corrugated cardboard is first placed on the main body of the support plate. Then, driven by the dual-axis motor, the main body of the support plate slowly rises carrying the cardboard. Simultaneously, the pusher plate performs a linear reciprocating motion at the speed of pushing one cardboard at a time. The time required for the main body of the support plate to lift one cardboard is controlled within one reciprocating cycle of the pusher plate, thus achieving automatic feeding, saving manpower and time, and improving the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A feeding device for a corrugated paper die-cutting machine includes an automatic feeding mechanism, an adjusting mechanism, and a controller. The automatic feeding mechanism has an adjusting mechanism at its upper end and a controller on one side. The automatic feeding mechanism includes a slide rail base, a servo motor at one end of the slide rail base, a reciprocating lead screw fixedly connected to the output end of the servo motor, a slider sleeved on the outer wall of the reciprocating lead screw, a push plate at the upper end of the slider, stop blocks fixedly connected to both ends of the slide rail base, a baffle at one end of the slide rail base, a side platform on one side of the slide rail base, a dual-axis motor on one side of the upper end of the side platform, gears fixedly connected to the output ends of the dual-axis motor, two grooves in the middle of the upper end of the side platform, toothed plates slidably connected to one side of the outer wall of each of the two grooves, and connecting plates fixedly connected to the middle of one side end of each of the two toothed plates.

[0008] Through the above technical solution, the device uses a controller to control a servo motor to drive a reciprocating screw to rotate. The rotation of the reciprocating screw causes a slider to move back and forth on the upper end of the slide rail base. At the same time, the push plate set on its upper end also moves back and forth, thus realizing the function of reciprocating pushing. Simultaneously, a dual-axis motor drives two gears to rotate and drives a toothed plate connected to the gears to slide up and down in the slide groove. The up and down sliding of the toothed plate causes the main body of the support plate and two side plates set in the middle of its outer wall to move up and down. During operation, a stack of corrugated cardboard is first placed on the main body of the support plate. Then, driven by the dual-axis motor, the main body of the support plate slowly rises carrying the cardboard. At the same time, the push plate moves in a straight line back and forth at the speed of pushing one cardboard at a time. The time required for the main body of the support plate to lift one cardboard is also controlled within one reciprocating cycle of the push plate, thereby realizing automatic feeding, saving manpower and time, and improving the practicality of the device.

[0009] Furthermore, the adjustment mechanism includes a support plate body, on both sides of the support plate body are provided with movable grooves, on one side of the outer wall of each of the two movable grooves are provided with an adjustment groove, both ends of the two movable grooves are fixedly connected with guide rods, one end of each of the multiple guide rods is fixedly connected with a connecting block, one end of each of the multiple connecting blocks is rotatably connected with a support rod, one end of each pair of support rods is rotatably connected with a rotating connecting part, one end of each pair of rotating connecting parts is provided with a side plate, the lower end of each pair of connecting blocks is threadedly connected with an adjustment screw, one end of each pair of adjustment screws is fixedly connected with a knob, and one side of the upper end face of each pair of side plates is fixedly connected with a limit plate.

[0010] Through the above technical solution, the device rotates the knob to make the adjusting screw rotate at the lower end of the two connecting blocks, thereby causing the two connecting blocks to approach each other in the movable groove with the guide rod as the starting point. At the same time, the support rods rotating at one end of the two connecting blocks abut against each other and rotate in unison toward both sides of the receiving plate body under the connection of the rotating connection part. At the same time, the side plates set on the outer wall of the rotating connection part also move toward both sides of the receiving plate body, realizing the extension of the bearing plate body. This enables the bearing of corrugated cardboard of different sizes and improves the practicality of the device.

[0011] Furthermore, the reciprocating lead screw passes through one end face of the slider and is fixedly connected to the output end of the servo motor, and the lower end of the slider is slidably connected to the upper end of the slide rail base;

[0012] Through the above technical solution, this setting enables the reciprocating screw to have a stable rotation fulcrum and the slider to slide back and forth on the slide rail base along the straight trajectory of the reciprocating screw.

[0013] Furthermore, the upper end of the baffle is set at the same height as the lower end of the push plate;

[0014] Through the above technical solution, this setting enables the baffle to hold the remaining cardboard below it in place when the pusher pushes the top corrugated cardboard, preventing it from falling off due to the movement of the cardboard above.

[0015] Furthermore, toothed plates are meshed and connected to one side of the outer wall of each of the two gears. The two toothed plates penetrate the middle of the upper end face of the side platform and are slidably connected to one side of the outer wall of the slide groove. The two connecting plates penetrate one end face of the slide groove and are fixedly connected to the middle of one end face of the toothed plate.

[0016] Through the above technical solution, this setting enables the toothed plate to slide smoothly in the groove and to lift the main body of the bearing plate to the specified position as required.

[0017] Furthermore, the lower end of the main body of the bearing plate is located in the middle of the outer wall of the connecting plate;

[0018] Through the above technical solution, this setting enables the main body of the support plate to slide up and down in the groove along with the connecting plate and be raised to the corresponding height.

[0019] Furthermore, the lower ends of the two connecting blocks pass through the adjusting groove and are threaded to the outer wall of the adjusting screw, and the length of the two adjusting screws is greater than the distance between the lower ends of the two connecting blocks;

[0020] Through the above technical solution, this setting enables the adjusting screw to adjust the distance between the two connecting blocks normally without being blocked by other components.

[0021] Furthermore, the total extension width of the two side plates does not exceed the total length of the connecting plate, and the maximum lifting height of the upper surface of the bearing plate body is consistent with the height of the lower surface of the push plate and the upper surface of the baffle plate.

[0022] Through the above technical solution, this setting enables the main body of the bearing plate to flexibly adjust the spacing between the side plates within a normal range and smoothly cooperate with the push plate to complete the subsequent material cutting work.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes a feeding device for a corrugated paper die-cutting machine. The device uses a controller to control a servo motor to drive a reciprocating lead screw to rotate. The rotation of the reciprocating lead screw causes a slider to move back and forth on the upper end of the slide rail base. At the same time, the push plate set on the upper end of the slider also moves back and forth, thus realizing the function of reciprocating pushing. Simultaneously, a dual-axis motor drives two gears to rotate and drives a toothed plate connected to the gears to slide up and down in the slide groove. The up and down sliding of the toothed plate causes the main body of the support plate and two side plates set in the middle of its outer wall to move up and down. During operation, a stack of corrugated cardboard is first placed on the main body of the support plate. Then, driven by the dual-axis motor, the main body of the support plate carrying the cardboard slowly rises. At the same time, the push plate moves in a straight line back and forth at the speed of pushing one cardboard at a time. The time required for the main body of the support plate to lift one cardboard is also controlled within one reciprocating cycle of the push plate, thereby realizing automatic feeding, saving manpower and time, and improving the practicality of the device.

[0025] 2. The present invention proposes a feeding device for a corrugated paper die-cutting machine. The device rotates a knob to make the adjusting screw rotate at the lower end of the two connecting blocks, thereby causing the two connecting blocks to approach each other in the movable groove with the guide rod as the starting point. At the same time, the support rods rotating at one end of the two connecting blocks abut against each other and rotate in unison toward both sides of the receiving plate body under the connection of the rotating connecting part. At the same time, the side plates set on the outer wall of the rotating connecting part also move toward both sides of the receiving plate body, realizing the extension of the receiving plate body. This enables the bearing of corrugated cardboard of different sizes and improves the practicality of the device. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] A feeding device for a corrugated paper die-cutting machine includes an automatic feeding mechanism 1, an adjusting mechanism 2, and a controller 3. The adjusting mechanism 2 is located at the upper end of the automatic feeding mechanism 1, and the controller 3 is located on one side of the automatic feeding mechanism 1. The automatic feeding mechanism 1 includes a slide rail base 101, a servo motor 102 is located at one end of the slide rail base 101, and a reciprocating lead screw 103 is fixedly connected to the output end of the servo motor 102. A slider 104 is sleeved on the outer wall of the reciprocating lead screw 103, and a push plate 105 is located at the upper end of the slider 104. Both ends of the base 101 are fixedly connected to stop blocks 106. A baffle 107 is provided at one end of the slide rail base 101. A side platform 108 is provided on one side end face of the slide rail base 101. A dual-axis motor 109 is provided on one side of the upper end face of the side platform 108. Gears 110 are fixedly connected to the output ends of the dual-axis motor 109. Two sliding grooves 111 are provided in the middle of the upper end face of the side platform 108. Toothed plates 112 are slidably connected to one side of the outer wall of each of the two sliding grooves 111. Gears 110 are fixedly connected to the middle of one side end face of each of the two toothed plates 112. The connecting plate 113, the device controls the servo motor 102 via the controller 3 to drive the reciprocating screw 103 to rotate. The rotation of the reciprocating screw 103 drives the slider 104 to reciprocate on the upper end of the slide rail base 101. At the same time as the slider 104 reciprocates, the push plate 105 set on its upper end also reciprocates, thus realizing the function of reciprocating push. At the same time, the dual-axis motor 109 drives the two gears 110 to rotate and drives the toothed plate 112, which is meshed with the gears 110, to slide up and down in the slide groove 111. The up and down sliding of the toothed plate 112 drives the push plate 105 set on its upper end to move back and forth. The main body 201 of the bearing plate in the middle of its outer wall and the two side plates 208 move up and down. When working, a stack of corrugated cardboard is first placed on the main body 201 of the bearing plate. Then, driven by the dual-axis motor 109, the main body 201 of the bearing plate slowly rises carrying the cardboard. At the same time, the push plate 105 makes a linear reciprocating motion at the speed of pushing one cardboard at a time. The time required for the main body 201 of the bearing plate to lift one cardboard is also controlled within one reciprocating cycle of the push plate 105. This realizes automatic feeding, saves manpower and time, and improves the practicality of the device.

[0036] Reference Figure 3-5The adjusting mechanism 2 includes a support plate body 201. Movable grooves 202 are formed on both end faces of the support plate body 201. Adjusting grooves 203 are formed on one side of the outer wall of each of the two movable grooves 202. Guide rods 204 are fixedly connected to both ends of each of the two movable grooves 202. Connecting blocks 205 are fixedly connected to one end of each of the multiple guide rods 204. Support rods 206 are rotatably connected to one end of each of the multiple connecting blocks 205. Rotary connecting parts 207 are rotatably connected to one end of each pair of support rods 206. Side plates 208 are provided at one end of each pair of rotating connecting parts 207. Adjusting screws 209 are threadedly connected to the lower end of each pair of connecting blocks 205. Knobs 210 are fixedly connected to one end of each pair of adjusting screws 209. Limiting plates 211 are fixedly connected to one side of the upper end of the side plate 208. The device rotates the knob 210 to make the adjusting screw 209 rotate at the lower end of the two connecting blocks 205, so that the two connecting blocks 205 approach each other in the movable groove 202 with the guide rod 204 as the starting point. At the same time, the support rods 206 at one end of the two connecting blocks 205 are connected by the rotating connection part 207 and they abut against each other and rotate towards both sides of the receiving plate body 201. At the same time, the side plate 208 set on the outer wall of the rotating connection part 207 also moves towards both sides of the receiving plate body 201, realizing the extension of the bearing plate body 201. Thus, it can support corrugated cardboard of different sizes and improve the practicality of the device.

[0037] The reciprocating lead screw 103 passes through one end face of the slider 104 and is fixedly connected to the output end of the servo motor 102. The lower end of the slider 104 is slidably connected to the upper end of the slide rail base 101. This arrangement allows the reciprocating lead screw 103 to have a stable rotation fulcrum and the slider 104 to slide back and forth on the slide rail base 101 along the straight trajectory of the reciprocating lead screw 103.

[0038] The upper end of the baffle 107 is set at the same height as the lower end of the push plate 105. This setting allows the baffle 107 to hold the other cardboard below it in place when the push plate 105 pushes the uppermost corrugated cardboard, preventing it from being affected by the movement of the upper cardboard and falling off.

[0039] Two gears 110 are meshed with toothed plates 112 on one side of their outer walls. The two toothed plates 112 penetrate the middle of the upper end face of the side platform 108 and are slidably connected to one side of the outer wall of the slide groove 111. Two connecting plates 113 penetrate one end face of the slide groove 111 and are fixedly connected to the middle of one end face of the toothed plates 112. This arrangement allows the toothed plates 112 to slide smoothly in the slide groove 111 and to lift the main body of the bearing plate 201 to the specified position as required.

[0040] The lower end of the bearing plate body 201 is located in the middle of the outer wall of the connecting plate 113. This arrangement allows the bearing plate body 201 to slide up and down in the slide groove 111 along with the connecting plate 113 and be raised to the corresponding height.

[0041] The lower ends of the two connecting blocks 205 pass through the adjusting groove 203 and are threaded to the outer wall of the adjusting screw 209. The length of the two adjusting screws 209 is greater than the distance between the lower ends of the two connecting blocks 205. This arrangement allows the adjusting screws 209 to adjust the distance between the two connecting blocks 205 normally without being blocked by other components.

[0042] The total extension width of the two side plates 208 does not exceed the total length of the connecting plate 113. The maximum lifting height of the upper surface of the bearing plate body 201 is consistent with the height of the lower surface of the push plate 105 and the upper surface of the baffle 107. This setting allows the bearing plate body 201 to flexibly adjust the spacing of the side plates 208 within the normal range and cooperate smoothly with the push plate 105 to complete the subsequent material feeding work.

[0043] Working principle: The device controls the servo motor 102 via controller 3 to drive the reciprocating screw 103 to rotate. The rotation of the reciprocating screw 103 drives the slider 104 to reciprocate on the upper end of the slide rail base 101. While the slider 104 is reciprocating, the push plate 105 set on its upper end also reciprocates, thus realizing the function of reciprocating push. At the same time, the dual-axis motor 109 drives the two gears 110 to rotate and drives the toothed plate 112, which is meshed with the gears 110, to slide up and down in the slide groove 111. The up and down sliding of the toothed plate 112 drives the support plate body 201 and the two side plates 208 set in the middle of its outer wall to move up and down. During operation, a stack of corrugated cardboard is first placed on the support plate body 201. Then, driven by the dual-axis motor 109, the support plate body 201 carrying the cardboard slowly rises. At the same time, the push plate 105 pushes up and down with each push. The device moves a cardboard sheet in a linear reciprocating motion at the speed of a single sheet. The time required for the main body 201 of the support plate to lift each cardboard sheet is also controlled within one reciprocating cycle of the push plate 105, thus achieving automatic feeding. The device rotates the knob 210 to make the adjusting screw 209 rotate at the lower end of the two connecting blocks 205, thereby causing the two connecting blocks 205 to approach each other in the movable groove 202 with the guide rod 204 as the starting point. At the same time, the support rods 206 rotating at one end of the two connecting blocks 205 abut against each other and rotate in unison toward both sides of the main body 201 of the support plate under the connection of the rotating connecting part 207. At the same time, the side plate 208 set on the outer wall of the rotating connecting part 207 also moves toward both sides of the main body 201 of the support plate, thereby extending the main body 201 of the support plate and thus enabling the support of corrugated cardboard of different sizes.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
