Description

Technical Field

[0001] This utility model relates to the field of packaging paper edge cutting technology, specifically to a composite packaging paper edge cutting device with adjustable cutter position. Background Technology

[0002] Composite packaging paper is a processed paper made by bonding paper, paperboard, aluminum foil, and cloth together with adhesives. Composite packaging paper not only improves the appearance and strength of the paper and paperboard, but more importantly, enhances properties such as water resistance, moisture resistance, oil resistance, and airtight aroma retention. It also gains heat-sealing properties, light-blocking properties, and heat resistance. During production, packaging paper is typically wound onto packaging rolls, and in final production, the edges of the packaging paper need to be trimmed to meet specified dimensions.

[0003] Chinese patent CN214136225U discloses a cutting device for composite packaging paper, which includes a fixed frame fixedly mounted on the frame of a laminating machine. A support base is fixedly mounted on the fixed frame, and a first cutter for cutting one side of the composite packaging paper is mounted on the support base. A placement mechanism is provided on the fixed frame, and a telescopic drive member that extends and retracts along the conveying direction of the non-laminating machine is fixedly mounted on the placement mechanism. A moving drive member is fixedly mounted on the output shaft of the telescopic drive member, and a second cutter for cutting the other side of the composite packaging paper is mounted on the output shaft of the moving drive member. This patent uses the telescopic drive member to move the cutter, causing the cutter to contact the packaging paper roll, thereby cutting off the edge of the packaging paper.

[0004] This existing technology typically uses telescopic drive components (such as cylinders, hydraulic cylinders, or electric push rods) to move the cutter, thereby adjusting its position to meet the production needs of packaging paper of different widths or shapes. However, this telescopic drive-based adjustment method has revealed a series of problems in practical applications, especially in situations requiring high cutting precision. Specifically, while the telescopic drive component can control the displacement of the cutter, its positioning accuracy is often limited by the mechanical characteristics of the drive mechanism and the stability of the control system, resulting in relatively low cutter movement precision. This lack of precision is particularly noticeable during long-term continuous operation, easily causing over-cutting of the packaging paper, i.e., the cut edge exceeds the predetermined range, thus compromising the integrity and aesthetics of the packaging paper. Traditional edge-cutting devices also lack real-time cutting position monitoring capabilities. During the cutting process, operators cannot intuitively understand the actual position of the cutter, nor can they correct cutting deviations in a timely manner. This lack of feedback further increases the risk of over-cutting and also poses challenges to the stability and consistency of production quality. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for composite packaging paper. By improving the method of adjusting the position of the cutter and monitoring the position of the cutter in real time, the over-cutting of the packaging paper can be avoided.

The device includes a main body with a mounting groove at the center of its top for placing the packaging paper roll. Both ends of the main body are provided with cutter adjustment components for cutting the packaging paper. Each cutter adjustment component includes a cutter assembly, a first adjustment component, and a second adjustment component for adjusting the position of the cutter assembly. The second adjustment component is mounted on the main body and drives the first adjustment component to reciprocate. The device also includes a first detection component and a second detection component for detecting the position of the cutter assembly. The second adjustment component includes a fixed plate fixed to the main body. The first adjustment component includes a movable plate slidably mounted on the fixed plate. Two guide rods are provided on the movable plate along its length, and a sliding plate is slidably mounted on the guide rods. The cutter assembly is mounted on the sliding plate.

[0007] Preferably, the first detection component includes a first laser emitter fixed to the bottom of the slide plate, and the first detection component also includes a first photoelectric sensor installed along the length of the moving plate. The light emitted by the first laser emitter is received by the first photoelectric sensor for real-time detection of the position of the cutting blade assembly.

[0008] Preferably, the second detection component includes a second laser emitter fixed to the bottom of the movable plate, and the second detection component also includes a second photoelectric sensor installed along the length of the fixed plate. The light emitted by the second laser emitter is received by the second photoelectric sensor for real-time detection of the position of the second adjustment component.

[0009] Preferably, the first adjustment assembly further includes a protective shell fixed to the movable plate, the protective shell being positioned directly above the movable plate, a first gear rotatably disposed within the protective shell, and a second gear rotatably disposed within the protective shell and meshing with the first gear, a first rotary drive component fixed to the outside of the protective shell, the output end of the first rotary drive component being fixedly connected to the second gear, an internal thread being provided at the center position of the first gear, and the first adjustment assembly further includes a threaded rod, one end of which is fixedly connected to the slide plate, an external thread being provided on the threaded rod, the external thread of the threaded rod meshing with the internal thread of the first gear.

[0010] Preferably, the second adjustment component further includes a second rotary drive fixed on the fixed plate, and the second adjustment component further includes a first lead screw arranged along the length direction of the fixed plate. The output end of the second rotary drive is fixedly connected to one end of the first lead screw, and the first lead screw is connected to the moving plate through a threaded sleeve.

[0011] Preferably, the cutter assembly includes a third rotary drive fixed on the slide plate, and the output end of the third rotary drive is connected to the cutter body.

[0012] Preferably, the main body is further provided with two clamping components at the mounting slot for clamping and rotating the packaging paper roller.

[0013] Preferably, the clamping assembly includes a fourth rotary drive that can approach or move away from the packaging paper roller, the output end of the fourth rotary drive is connected to a rotary sleeve, and the rotary sleeve is fitted onto one end of the packaging paper roller.

[0014] Preferably, the clamping assembly further includes two slide rods fixed to the main body, one end of which is fixed to a mounting plate.

The clamping assembly also includes a support base, which is fixedly connected to the fourth rotary drive component, slidably connected to the slide rods, and threadedly connected to the second lead screw.

[0015] The advantages of this utility model compared to the prior art are:

[0016] 1. This application incorporates a first detection component and a second detection component in the cutter adjustment assembly. In the first detection component, a first laser emitter is mounted on the bottom of the slide plate, and a first photoelectric sensor is mounted on the moving plate. In the second detection component, a second laser emitter is mounted on the bottom of the moving plate, and a second photoelectric sensor is mounted on the top of the fixed plate. When the slide plate moves, the first laser emitter moves with the slide plate, and the light emitted by the first laser emitter is received by the first photoelectric sensor. Similarly, the second laser emitter moves with the moving plate, and the light emitted by the second laser emitter is received by the second photoelectric sensor. This provides real-time feedback on the position of the cutter body, preventing the cutter body from exceeding the predetermined range.

[0017] 2. This application employs a first gear and a threaded rod meshing. Since the first gear has an internal thread at its center, which meshes with the external thread of the threaded rod, the threaded rod will move when the first gear rotates. One end of the threaded rod is fixedly connected to the slide plate, so the slide plate and cutter assembly will also move with the movement of the threaded rod. By adjusting the rotation direction and speed of the first rotary drive, the movement direction and speed of the slide plate and cutter assembly can be precisely controlled. This causes the slide plate to move, while simultaneously sliding on the guide rod. This design not only ensures the stability of the slide plate position and cutter assembly adjustment but also improves the adjustment accuracy. Attached Figure Description

Detailed Implementation

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-7 As shown, this utility model provides a composite packaging paper edge-cutting device with adjustable cutter position, which cuts off the edge of the packaging paper roll. It includes a main body 1, with a mounting groove 11 for placing the packaging paper roll at the center of the top of the main body 1. Cutter adjustment components 12 for cutting the packaging paper are provided at both ends of the main body 1. Each cutter adjustment component 12 includes a cutter assembly 123 and further includes a first adjustment component 121 and a second adjustment component 122 for adjusting the position of the cutter assembly 123. The second adjustment component 122 is mounted on the main body 1 and is used for... The first adjustment component 121 is driven to move back and forth. The cutter adjustment component 12 also includes a first detection component 124 and a second detection component 125 for detecting the position of the cutter component 123. The second adjustment component 122 includes a fixed plate 1221 fixed on the main body 1. The first adjustment component 121 includes a movable plate 1211 slidably disposed on the fixed plate 1221. Two guide rods 1212 are disposed on the movable plate 1211 along the length direction of the movable plate 1211, and a slide plate 1216 is slidably disposed on the guide rods 1212. The cutter component 123 is disposed on the slide plate 1216.

[0028] When the position of the cutter needs to be adjusted, the position of the slide plate 1216 on the guide rod 1212 is adjusted by operating the first adjustment component 121, thereby changing the position of the cutter assembly 123 in the horizontal direction.

[0029] refer to Figures 4-6 As shown, the first detection component 124 includes a first laser emitter 1241 fixed to the bottom of the slide plate 1216. The first detection component 124 also includes a first photoelectric sensor 1242 installed along the length of the moving plate 1211. The light emitted by the first laser emitter 1241 is received by the first photoelectric sensor 1242 for real-time detection of the position of the cutter assembly 123.

[0030] When the cutter assembly 123 (and the slide plate 1216) moves, the first laser emitter 1241 fixed to the bottom of the slide plate 1216 also moves accordingly. The laser light emitted by the first laser emitter 1241 will illuminate the first photoelectric sensor 1242 installed along the length of the moving plate 1211. After receiving the laser light, the first photoelectric sensor 1242 converts it into an electrical signal and transmits this signal to the cutting device, which calculates the current position of the cutter assembly 123 based on the received signal.

[0031] The second detection component 125 includes a second laser emitter 1251 fixed to the bottom of the movable plate 1211. The second detection component 125 also includes a second photoelectric sensor 1252 installed along the length of the fixed plate 1221. The light emitted by the second laser emitter 1251 is received by the second photoelectric sensor 1252 for real-time detection of the position of the second adjustment component 122.

[0032] When the slide plate 1216 moves, the first laser emitter 1241 moves with the slide plate 1216, and the light emitted by the first laser emitter 1241 is received by the first photoelectric sensor 1242. Similarly, the second laser emitter 1251 moves with the moving plate 1211, and the light emitted by the second laser emitter 1251 is received by the second photoelectric sensor 1252, thereby providing real-time feedback on the position of the cutter body 1232 and preventing the cutter body 1232 from exceeding the predetermined range.

[0033] The first adjustment assembly 121 also includes a protective shell 1214 fixed on the movable plate 1211. The protective shell 1214 is located directly above the movable plate 1211. A first gear 1217 is rotatably disposed in the protective shell 1214, and a second gear 1218 that meshes with the first gear 1217 is also rotatably disposed in the protective shell 1214. A first rotary drive 1213 is also fixed to the outside of the protective shell 1214. The output end of the first rotary drive 1213 is fixedly connected to the second gear 1218. An internal thread is provided at the center of the first gear 1217. The first adjustment assembly 121 also includes a threaded rod 1215. One end of the threaded rod 1215 is fixedly connected to the slide plate 1216. An external thread is provided on the threaded rod 1215, and the external thread of the threaded rod 1215 meshes with the internal thread of the first gear 1217.

[0034] When the first rotary drive 1213 is activated, its output end drives the second gear 1218 to rotate. The second gear 1218 meshes with the first gear 1217, so the first gear 1217 will also rotate. Since the first gear 1217 has an internal thread at its center, which meshes with the external thread of the threaded rod 1215, the threaded rod 1215 will move when the first gear 1217 rotates. One end of the threaded rod 1215 is fixedly connected to the slide plate 1216, so the slide plate 1216 (and the cutter assembly 123) will also move with the movement of the threaded rod 1215. By adjusting the rotation direction and speed of the first rotary drive 1213, the movement direction and speed of the slide plate 1216 (and the cutter assembly 123) can be precisely controlled.

[0035] When the first gear 1217 rotates, the threaded rod 1215 moves, which in turn causes the slide plate 1216 to move. At the same time, the slide plate 1216 slides on the guide rod 1212. This design not only ensures the stability of the position adjustment of the slide plate 1216, but also improves the accuracy of the adjustment.

[0036] The second adjustment assembly 122 also includes a second rotary drive 1223 fixed on the fixed plate 1221. The second adjustment assembly 122 also includes a first lead screw 1222 arranged along the length of the fixed plate 1221. The output end of the second rotary drive 1223 is fixedly connected to one end of the first lead screw 1222. The first lead screw 1222 is connected to the moving plate 1211 through a threaded sleeve.

[0037] When the second rotary drive 1223 is activated, its output end drives the first lead screw 1222 to rotate. When the first lead screw 1222 rotates, the threaded sleeve moves horizontally along the length of the first lead screw 1222 through the interaction of the threads, thereby adjusting the position of the cutter assembly 123.

[0038] The cutter assembly 123 includes a third rotary drive 1231 fixed on the slide plate 1216, and the output end of the third rotary drive 1231 is connected to the cutter body 1232.

[0039] refer to Figure 7As shown, the main body 1 is also provided with two clamping assemblies 13 at the mounting groove 11 for clamping and rotating the packaging paper roller. The clamping assembly 13 includes a fourth rotary drive 135 that can approach or move away from the packaging paper roller. The output end of the fourth rotary drive 135 is connected to a rotating sleeve 136, which is sleeved on one end of the packaging paper roller. The clamping assembly 13 also includes two slide rods 131 fixed to the main body 1. One end of the slide rod 131 is fixed to a mounting plate 132. The clamping assembly 13 also includes a second lead screw 134 disposed between the main body 1 and the mounting plate 132. One end of the second lead screw 134 is fixed to a handwheel 137. The clamping assembly 13 also includes a support base 133. The support base 133 is fixedly connected to the fourth rotary drive 135, slidably connected to the slide rods 131, and threadedly connected to the second lead screw 134.

[0040] When it is necessary to clamp the packaging paper roller, turn the handwheel 137. The rotation of the handwheel 137 will drive the second lead screw 134 to rotate. Since the support seat 133 and the second lead screw 134 are connected by threads, when the second lead screw 134 rotates, the support seat 133 will slide along the slide rod 131, thereby causing the rotating sleeve 136 to be fitted onto the packaging paper roller.

[0041] Working Principle: When using this device, firstly, place the packaging paper roller with the packaging paper attached into the mounting groove 11. Then, by rotating the handwheel 137, the rotation of the handwheel 137 drives the second lead screw 134 to rotate. The rotation of the second lead screw 134 further drives the support base 133 to move, and the movement of the support base 133 drives the fourth rotary drive member 135 to move. The fourth rotary drive member 135 causes the rotating sleeve 136 to clamp the packaging paper roller, thereby fixing the packaging paper roller. Next, start the first rotary drive member 1213. The rotation of the first rotary drive member 1213 drives the second gear 1218 to rotate, and the meshing of the second gear 1218 with the first gear 1217 causes the first gear 1217 to rotate. The rotation of the first gear 1217 further drives the threaded rod 1215 to move, and the movement of the threaded rod 1215 drives the slide plate 1216 to move. The movement of the slide plate 1216 adjusts the cutter body 1232 to the predetermined cutting position. Subsequently, the second rotary drive 1223 is activated. The rotation of the second rotary drive 1223 drives the first lead screw 1222 to rotate, which in turn moves the moving plate 1211. The movement of the moving plate 1211 brings the cutter body 1232 into contact with the packaging paper, preparing for cutting. At this time, the third rotary drive 1231 is activated, driving the cutter body 1232 to rotate and begin cutting the packaging paper. Simultaneously, the fourth rotary drive 135 is activated, driving the rotating sleeve 136 to rotate. The rotation of the rotating sleeve 136 then drives the packaging paper roller to rotate, thereby achieving continuous edge cutting of the packaging paper. During the movement of the slide plate 1216, the first laser emitter 1241 follows the slide plate 1216 and emits light, which is received by the first photoelectric sensor 1242. Similarly, the second laser emitter 1251 moves with the moving plate 1211 and emits light, which is received by the second photoelectric sensor 1252. This design can provide real-time feedback on the position information of the cutter body 1232, ensuring that the cutter body 1232 always stays within the predetermined cutting range and avoids overcutting or undercutting.

[0042] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
