Description

Technical Field

[0001] The invention relates to a tongue making device, belonging to the technical field of paper bag making equipment. Background Art

[0002] The paper bag machine is a special equipment for producing paper bags. The tongue making device is an important part of the paper bag machine. The tongue making device includes a window opening component and a bottom roller point breaking device. The shape of the tongue is cut at the window opening component. The cutting parts are on both sides of the tongue. The cutting direction is as large as along the height direction of the paper bag. The bottom roller point breaking device performs point breaking processing on the top and both sides of the tongue, so as to separate the paper bag from the paper at the point breaking point to become a single paper bag. The window opening component is disclosed in the Chinese utility model patent with the authorization announcement number CN215620386U. This patent The disclosed window opening component comprises a frame plate, a lower rotating roller is arranged on the frame plate, an upper rotating roller is arranged above the lower rotating roller, a window opening knife is detachably arranged on the upper rotating roller, the upper rotating roller is transmission-connected to the first motor, the first motor and the upper rotating roller are arranged on a movable frame, an adjusting screw is rotatably arranged on the frame plate, and the adjusting screw is threadedly connected to the movable frame. The window opening component disclosed in the above patent cannot remove the paper scraps generated after the window is opened and the window is cut out well, and the paper scraps after cutting need to be cleaned frequently, which is not conducive to the continuous window opening processing of the paper bag. Meanwhile, cleaning the paper scraps separately also reduces the processing efficiency of the paper bag. The Chinese utility model patent with the authorization announcement number CN207901738U discloses a point breaking mechanism of a paper bag machine, wherein a serrated knife is installed on the point breaking roller through a serrated knife clamp and a locking bolt, and the serrated knife is symmetrically arranged on both sides of the point breaking roller, and the position of the serrated knife on the point breaking roller is not adjustable. Therefore, when the point breaking roller rotates once, the width of the cut on the paper bag is specific, so it cannot be properly adjusted according to the size of the processed paper bag, which makes the above-mentioned point breaking mechanism poor in versatility. Summary of the invention

[0003] The object of the present invention is to provide a tongue making device to solve the technical defects in the prior art that the window opening component of the tongue making device lacks the ability to remove paper scraps generated after window opening, thus affecting the continuous production of paper bags, and the point breaking mechanism of the tongue making device is only suitable for processing paper bags of a specific size, thus having poor versatility.

[0004] To solve the above problems, the technical solution adopted by the present invention is: a tongue and mouth manufacturing device, including a windowing component and a bottom roller intermittent cutting device. The paper for manufacturing paper bags passes through the windowing component and the bottom roller intermittent cutting device successively, opening windows on the paper and performing pre-piercing processing on the paper before attaching the handle; the windowing component includes a windowing frame, a support roller, a cutting roller, a support roller drive motor, and a waste suction device. Both ends of the support roller and the cutting roller are rotatably installed on the windowing frame. A die matching the shape of the windowing part on the paper bag is provided on the cutting roller. In the use state, the die cuts out a window on the paper for making the paper bag. The support roller drive motor drives the support roller to rotate for conveying the paper between the support roller and the cutting roller. The waste suction device is used to suck up the paper scraps generated by the die pressing out cut marks on the paper; the bottom roller intermittent cutting device includes an intermittent cutting frame and a bottom roller intermittent cutting mechanism and a rubber roller provided on the intermittent cutting frame. Both ends of the rubber roller are rotatably connected to the intermittent cutting frame and are driven by a rubber roller drive motor to rotate relative to the intermittent cutting frame. The bottom roller intermittent cutting mechanism includes a bottom roller, an intermittent cutting knife, and an arc plate. Both ends of the bottom roller are rotatably arranged on the intermittent cutting frame and are driven by a bottom roller drive motor to rotate relative to the intermittent cutting frame. A plurality of kidney-shaped holes are opened on the arc plate, and an arc-shaped notch is opened on the bottom roller. The arc plate is detachably installed in the arc-shaped notch by bolts passing through the kidney-shaped holes and threadedly engaged with the bottom roller. The groove wall of the arc-shaped notch and the surface of the arc plate corresponding to the groove wall of the arc-shaped notch are tool mounting surfaces. The intermittent cutting knife is installed on the tool mounting surface. The arc plate moves in the arc-shaped notch to adjust the distance between the two intermittent cutting knives. In the use state, the paper passes between the bottom roller intermittent cutting mechanism and the rubber roller, and the intermittent cutting knife performs pre-piercing processing on the paper. The present invention is provided with a waste suction device. When opening a window on the paper bag, the waste suction device directly sucks up the paper scraps generated by cutting out the window, so that the surface of the paper for processing the paper bag has no paper scraps, ensuring the continuous production of the paper bag without the need to clean the surface of the paper separately, effectively improving the production efficiency of the paper bag; by opening an arc-shaped notch on the bottom roller in the present invention, since kidney-shaped holes are opened on the arc plate, the arc plate can be moved along the direction of the kidney-shaped holes, so as to adjust the distance between the intermittent cutting knives installed on the tool mounting surfaces of the arc plate and the bottom roller, so that the distance between the two intermittent cutting knives can be adjusted according to actual needs to make it suitable for the intermittent cutting processing of paper bags of different sizes, improving the versatility of the present invention.

[0005] As a further improvement of the present invention, the waste suction device includes a blower, a paper scrap collection box, and a waste suction pipe. One end of the waste suction pipe is communicated with the paper scrap collection box, and the other end of the waste suction pipe is provided with a waste suction port. The waste suction port is arranged at the support roller. The blower is communicated with the waste suction pipe. The blower blows air into the paper scrap collection box and forms a negative pressure in the waste suction pipe to suck the paper scraps generated by opening the window on the paper into the paper scrap collection box. In the present invention, the blower blows air into the waste suction pipe. Through the flow of air in the waste suction pipe, a negative pressure is generated in the waste suction pipe, sucking the paper scraps generated by windowing into the waste suction pipe and finally collecting them in the paper scrap collection box.

[0006] As a further improvement of the present invention, one end of the waste suction pipe for communicating with the paper scrap collection box includes an inner pipe unit and an outer pipe unit. One end of the inner pipe unit close to the paper scrap collection box extends into the outer pipe unit. One end of the outer pipe unit far from the paper scrap collection box is fixedly sealed with the outer surface of the inner pipe unit, forming an inner cavity between the outer pipe unit and the inner pipe unit. The air outlet of the blower communicates with the inner cavity. The blower blows air into the inner cavity, and the air flows from the inner cavity to the paper scrap collection box and generates negative pressure in the inner pipe unit, which is used to suck the paper scraps into the waste suction pipe. In the present invention, since the blower blows air into the inner cavity between the inner pipe unit and the outer pipe unit, the air in the inner cavity flows towards the paper scrap collection box and flows through the pipe orifice of the inner pipe unit. The flow of the air entering the pipe orifice of the inner pipe unit generates negative pressure in the inner pipe unit, attracting the paper scraps by the inner pipe unit, sucking the paper scraps towards the inner pipe unit, and after exiting the inner pipe unit, being blown into the paper scrap collection box along with the air blown by the blower.

[0007] As a further improvement of the present invention, the outer pipe unit includes a first pipe body, a second pipe body and a third pipe body. Both the first pipe body and the second pipe body are cylindrical, and the inner diameter of the first pipe body is greater than the inner diameter of the third pipe body. The second pipe body is a conical cylinder with the inner diameters of both ends being equal to the inner diameters of the first pipe body and the third pipe body respectively. One end of the first pipe body far from the second pipe body is fixedly connected to the inner pipe unit by a conical connecting piece. One end of the inner pipe unit close to the paper scrap collection box extends into the second pipe body. The air outlet of the blower communicates with the inner cavity at the first pipe body. In the present invention, due to the shape of the second pipe body in the outer pipe unit, the flow rate of the air in the inner cavity is changed, increasing the negative pressure formed at the pipe orifice of the inner pipe unit, which is more conducive to sucking the paper scraps from the paper.

[0008] As a further improvement of the present invention, it further includes a support roller support and a cutting roller support. The support roller support is arranged on the frame and holds the support roller from the bottom upwards to prevent the support roller from bending downward. The cutting roller support is installed on the frame and holds the cutting roller from above to prevent the cutting roller from bending upward. In the present invention, through the support roller support and the cutting roller support, the support roller and the cutting roller are supported from the middle, which can effectively prevent the two from bending and deforming under the force during use.

[0009] As a further improvement of the present invention, the support roller support and the cutting roller support have the same structure, both including a support seat and two rollers. The support seat is installed on the windowed frame, and the two rollers are rotatably installed on the support seat. The lower part of the support roller is supported by the two rollers of the support roller support, and the two rollers of the support roller support roll on the support seat as the support roller rotates. The upper part of the cutting roller is supported by the two rollers of the cutting roller support, and the two rollers of the cutting roller support rotate on its support seat as the cutting roller rotates. The support roller support and the cutting roller support in the present invention are provided with rollers. By the cooperation of the rollers with the support roller and the cutting roller, the resistance to the support roller and the cutting roller is reduced.

[0010] As a further improvement of the present invention, the bottom roller cutting mechanism further includes a tool pressing seat, and the cutting tool is pressed on the tool mounting surface by the tool pressing seat. By setting the tool pressing seat, the present invention clamps the cutting tool between the tool mounting surface and the tool pressing seat to fix the cutting tool, which is convenient for the installation of the cutting tool.

[0011] As a further improvement of the present invention, through holes communicating with the tool mounting surface are provided on both the bottom roller and the arc-shaped plate. A threaded hole is provided on the tool pressing seat, and a bolt passing through the cutting tool and threadedly engaged with the threaded hole is arranged in the through hole for clamping the cutting tool between the tool pressing seat and the tool mounting surface. By providing through holes on the bottom roller and the arc-shaped plate, the present invention facilitates the installation of the bolts for fixing the cutting tool. The present invention can adjust the shape of the through hole, such as setting the through hole as a stepped through hole, so that the head of the bolt is hidden in the through hole to avoid damaging the paper for making bags.

[0012] As a further improvement of the present invention, the bottom roller cutting device further includes a rubber roller moving frame. Both ends of the rubber roller are rotatably connected to the rubber roller moving frame. The rubber roller moving frame is arranged on the cutting frame and forms a moving pair with the cutting frame. The rubber roller moves synchronously with the movement of the rubber roller moving frame for adjusting the distance between the rubber roller and the bottom roller. By setting the rubber roller moving frame, the present invention adjusts the position of the rubber roller by the movement of the rubber roller moving frame on the frame, thereby adjusting the distance between the rubber roller and the bottom roller to be suitable for the cutting processing of paper bags with different thicknesses and facilitating the passing of the paper bag between the rubber roller and the bottom roller.

[0013] As a further improvement of the present invention, the rubber roller moving frame includes a slider, a guide rail and a driving mechanism. The guide rail is installed on the cutting frame. The slider is arranged on the guide rail and can slide along the length direction of the guide rail. The end of the rubber roller is rotatably connected to the slider. The driving mechanism is connected to the slider for driving the slider to move on the guide rail. With the cooperation of the slider and the guide rail in the present invention, the driving mechanism drives the slider to move, so that the slider slides along the length direction of the guide rail, and the sliding of the slider drives the rubber roller to slide on the frame.

[0014] In summary, the beneficial effects of the present invention are as follows: The paper scraps generated after windowing on the paper bag are sucked and removed by the waste suction device, ensuring the surface cleanliness of the paper bag and facilitating the continuous processing of the paper bag. The positions between the cutting tools in the present invention are adjustable, so as to be suitable for the processing of paper bags of different sizes, improving the versatility.

The diameter of the bottom of the arc-shaped notch 209 in the present invention is equal to the inner diameter of the arc plate 206, and the outer diameter of the arc plate 206 is equal to the diameter of the part of the bottom roller 204 outside the arc-shaped notch 209. Therefore, after the arc plate 206 is installed in the arc-shaped notch 209, the outer surface of the arc plate 206 and the arc-shaped outer surface of the bottom roller 204 are located on the same cylindrical surface. The arc plate 206 in the present invention is detachably installed in the arc-shaped notch 209 by bolts passing through the kidney-shaped holes 208 and threadedly engaged with the bottom roller 204. To achieve the above installation, a threaded hole 213 corresponding to the kidney-shaped hole 208 is provided at the bottom of the arc-shaped notch 209. The optimal number of threaded holes 213 corresponding to each kidney-shaped hole 208 in the present invention is more than one, such as three threaded holes 213 corresponding to each kidney-shaped hole 208. The kidney-shaped hole 208 is stepped. After the arc plate 206 is installed in the arc-shaped notch 209 with bolts, the head of the bolt is located in the kidney-shaped hole 208. The groove wall of the arc-shaped notch 209 and the surface of the arc plate 206 corresponding to the groove wall of the arc-shaped notch 209 in the present invention are tool installation surfaces 210. The intermittent cutter 205 is installed on the tool installation surface 210. Since the kidney-shaped holes 208 are provided in the arc plate 206 in the present invention, the distance between the two intermittent cutters 205 can be adjusted by moving the arc plate 206 in the arc-shaped notch 209.

[0037] To facilitate the installation of the intermittent cutter 205, a tool pressing seat 211 is provided in the present invention. The tool pressing seat 211 is strip-shaped, and the intermittent cutter 205 is pressed on the tool installation surface 210 by the tool pressing seat 211. Through holes 212 communicating with the tool installation surface 210 are provided on both the bottom roller 204 and the arc plate 206. The center line of the through hole 212 is perpendicular to the tool installation surface 210, and the through hole 212 is a stepped hole. A threaded hole 213 is provided in the tool pressing seat 211. A bolt passing through the intermittent cutter 205 and threadedly engaged with the threaded hole 213 is provided in the through hole 212. The bolt is used to clamp the intermittent cutter 205 between the tool pressing seat 211 and the tool installation surface 210. Since the through hole 212 is a stepped hole, when the bolt is installed in the through hole 212, the head of the bolt will not protrude from the through hole 212.

[0038] The intermittent frame 201 in the present invention includes two intermittent wallboards 201-1 and multiple connecting rods (not shown in the figure) connecting the two intermittent wallboards 201-1. The two intermittent wallboards 201-1 are arranged in parallel. In the use state, the bottom of the intermittent wallboard 201-1 is supported by the ground. In the present invention, both ends of the rubber roller 202 are rotatably connected to the two intermittent wallboards 201-1 of the intermittent frame 201 by bearings. In the use state, the rubber roller 202 is driven by a rubber roller motor to rotate on the intermittent frame 201. In the present invention, both ends of the bottom roller 204 are rotatably connected to the two intermittent wallboards 201-1 of the intermittent frame 201 by bearings. The bottom roller driving motor 207 is used to drive the bottom roller 204 to rotate on the intermittent frame 201. The bottom roller driving motor 207 in the present invention is detachably installed on the motor seat 123 by bolts, and the motor seat 123 is detachably installed on one of the intermittent wallboards 201-1 by bolts. The output shaft of the bottom roller driving motor 207 is connected to one end of the bottom roller 204 by a coupling.

[0039] In order to conveniently adjust the distance between the stripping roller and the bottom roller 204 according to actual needs, the present invention is provided with a rubber roller moving frame 215. Both ends of the rubber roller 202 are rotatably connected to the rubber roller moving frame 215 by bearings. The rubber roller moving frame 215 is arranged on the intermittent frame 201 and forms a moving pair with the intermittent wallboard 201-1 of the intermittent frame 201. The rubber roller 202 moves synchronously with the movement of the rubber roller moving frame 215. By the movement of the rubber roller moving frame 215 on the intermittent frame 201, the rubber roller 202 moves on the intermittent frame 201 to adjust the distance between the rubber roller 202 and the bottom roller 204. The rubber roller moving frame 215 in the present invention includes a second slider 216, a guide rail 217 and a driving mechanism 218. The second slider 216 is a rectangular block. The guide rail 217 is installed on the intermittent frame 201. The second slider 216 is arranged on the guide rail 217 and can slide along the length direction of the guide rail 217. The end of the rubber roller 202 is rotatably connected to the second slider 216. The driving mechanism 218 in the present invention is connected to the second slider 216 and is used to drive the second slider 216 to move on the guide rail 217.

[0040] Such as Figure 9As shown, the drive mechanism 218 in the present invention specifically includes a second lead screw 203 and a fixing plate 214. The fixing plate 214 is detachably mounted on the upper part of the second slider 216 by bolts. The second lead screw 203 is parallel to the guide rail 217. In the present invention, preferably, both the second lead screw 203 and the guide rail 217 are arranged in the horizontal direction. One end of the second lead screw 203 is rotatably connected to the intermittent frame 201, and this rotational connection method is the prior art. The other end of the second lead screw 203 passes through the fixing plate 214 and is in threaded cooperation with the fixing plate 214. Preferably, a threaded sleeve 219 is fixedly mounted on the fixing plate 214. The second lead screw 203 passes through the threaded sleeve 219 and is in threaded cooperation with the threaded sleeve 219. Through the threaded cooperation between the second lead screw 203 and the threaded sleeve 219, the threaded cooperation between the second lead screw 203 and the fixing plate 214 is realized. When the second lead screw 203 rotates, the rotation of the second lead screw 203 is converted into the horizontal movement of the threaded sleeve 219. Therefore, the rotation of the second lead screw 203 can be used to drive the fixing plate 214 and the second slider 216 fixedly connected to the fixing plate 214 to slide on the guide rail 217. In the present invention, the forward rotation and reverse rotation of the second lead screw 203 are respectively used to drive the second slider 216 to reciprocate on the guide rail 217.

[0041] As Figure 11As shown in the figure, the specific structure for realizing the rotation of the rubber roller 202 in the present invention is as follows: A pulley A220 is provided at one end of the rubber roller 202. A fixed shaft 221 is provided on one of the breaking wallboards 201-1 of the breaking frame 201. There is no relative rotation between the fixed shaft 221 and the breaking wallboard 201-1. A pulley B222 and a pulley C223 are rotatably provided on the fixed shaft 221, and the pulley B222 and the pulley C223 rotate synchronously. In the present invention, the pulley B222 and the pulley C223 are detachably installed by bolts along the axial direction of the pulley B222 and the pulley C223 and kept rotating synchronously. The pulley C223 in the present invention is rotatably connected to the fixed shaft 221 by a bearing. The pulley A220 and the pulley B222 are connected by a synchronous belt A224. The pulley C223 in the present invention is used to be connected to the pulley on the output shaft of the rubber roller 202 motor by a synchronous belt B (not shown in the figure) in the use state. The rubber roller 202 motor drives the pulley C223 to rotate through the synchronous belt B, so that the pulley C223 and the pulley B222 rotate synchronously. Then, the pulley B222 drives the pulley A220 to rotate through the synchronous belt A224, thereby driving the rubber roller 202 to rotate relative to the breaking frame 201. In order to keep the synchronous belt A224 in a taut state and avoid slipping, a fixed frame 225 perpendicular to the fixed shaft 221 is provided on the fixed shaft 221. The fixed frame 225 can rotate relative to the fixed shaft 221. A tension pulley 226 is provided on the fixed frame 225. By the relative rotation of the fixed frame 225 and the fixed shaft 221, the position of the tension pulley 226 is adjusted. The synchronous belt A224 in the present invention bypasses the tension pulley 226. The fixed frame 225 rotates relative to the fixed shaft 221, and the tension degree of the synchronous belt A224 is adjusted by adjusting the position of the tension pulley 226.

[0042] The specific structure of the installation of the fixed frame 225 and the fixed shaft 221 in the present invention is as follows: The fixed frame 225 is in a rectangular plate-like structure. A clamping hole penetrating both sides is opened at one end of the fixed frame 225. A clamping groove 227 communicating with the clamping hole is opened at the end of the fixed frame 225. And a connection hole perpendicular to the clamping groove 227 is opened on the fixed frame 225. In the use state, a fixing bolt is provided in the connection hole. The fixing bolt passes through the connection hole, and a nut threadedly matched with the fixing bolt is provided on the fixing bolt. By screwing the fixing bolt, the clamping groove 227 contracts to clamp the fixed shaft 221 in the clamping hole, realizing the fixation of the fixed frame 225 and the fixed shaft 221. When the position of the tension pulley 226 needs to be adjusted, by loosening the fixing bolt, the clamping groove 227 opens, and looseness occurs between the fixed frame 225 and the fixed shaft 221, and the fixed frame 225 can be rotated as needed.
