Description

Technical Field

[0001] The invention relates to the technical field of decorative painting packaging, in particular to a decorative painting packaging device with a cutting function. Background Art

[0002] With the continuous improvement of living standards, people's requirements for the quality of life are getting higher and higher. Decorative paintings can not only beautify the environment, but also decorate the home.

[0003] In recent years, the production of decorative paintings has gradually introduced automated equipment, which has improved production efficiency to a certain extent. However, during continuous production, due to the different specifications and sizes of various types of decorative paintings, ordinary machines cannot identify the blank areas and coating areas of decorative paintings. When cutting and packaging, various parameters need to be manually adjusted, which affects the continuous production efficiency of decorative paintings.

[0004] In addition, because the decorative paintings are ultimately sold in the form of individual paintings, conventional packaging devices are not good at clamping and rolling up the decorative paintings. Summary of the invention

[0005] The object of the present invention is to provide a packaging device for decorative paintings with a cutting function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A packaging device for decorative paintings with a cutting function, the packaging device is used to package and cut the decorative paintings, the packaging device comprises a packaging table, a power device, a cutting device and a feeding roller, the feeding roller is rotatably connected to the packaging table, the feeding roller is used to feed the decorative paintings, the power device is connected to the packaging table, the cutting device is tightly connected to the packaging table, and the power device is used to roll up and package the decorative paintings.

[0008] The packing table serves as the main installation base for installing other devices. The power device serves as the main power source for conveying the decorative paintings and automatically rolling them up for packing. After rolling up, they are automatically cut by the cutting device to form decorative paintings. A transfer robot is set at the end of the conveying stroke to put the rolled decorative paintings into the packing box to complete the packaging.

[0009] Furthermore, a material guide trough is provided on the packaging table, and the power device includes a conveyor belt, a winding assembly and a positioning assembly. The conveyor belt is arranged along the material guide trough, and two power rollers are arranged on the inner circle of the conveyor belt. A plurality of fixed grooves are provided on both sides of the conveyor belt along the feeding direction, and suction cups are provided in the fixed grooves. A negative pressure flow channel is provided on the packaging table, and the suction cup and the negative pressure flow channel are intermittently connected, with the upper end of the suction cup facing the decorative painting. The length of the negative pressure flow channel is smaller than the feeding stroke of the material guide trough, and the positioning assembly and the winding assembly are arranged sequentially along the feeding direction.

[0010] The conveyor belt is guided by the material guide trough, and the power roller has a built-in power motor to drive the outer roller to rotate, thereby driving the conveyor belt to make a rotary motion. The conveyor belt fixes the suction cups through several fixed grooves on both sides. The suction cups are intermittently connected to the negative pressure flow channel within the conveying stroke, that is, the conduction state is maintained during the front-end conveying process, and the decorative painting is driven forward by negative pressure adsorption; when it moves to the end, the suction cup at the end is no longer connected to the negative pressure flow channel due to the set length difference, which facilitates the automatic winding of the decorative painting by the winding component, and the blank areas on both sides of the decorative painting are identified by the positioning component to prevent damage to the coating area of ​​the decorative painting and affect the quality of the painting.

[0011] Furthermore, the positioning assembly includes a support plate, an emergent light source and a photosensitive layer. There are two support plates, which are respectively fastened to the packaging table, and are respectively located on both sides of the feeding direction. An emergent light source is provided on the support plate, and the emergent light source faces the surface of the decorative painting. A plurality of photosensitive layers are provided on the support plate, and the plurality of photosensitive layers are horizontally arranged perpendicular to the feeding direction. Two electrodes are provided on each photosensitive layer, and the two electrodes on the same photosensitive layer are respectively electrically connected to the two wiring terminals of the power supply to form a ranging circuit. The photosensitive layer is located on the reflected light path of the emergent light source.

[0012] By setting the outgoing light source, an inclined arrangement can be adopted. After irradiating the decorative painting, a reflected light path is formed, and irradiating the photosensitive layer to excite electron-hole pairs. The ranging circuit composed of two electrodes and a power supply is turned on. The greater the light intensity, the greater the current of the ranging circuit. When irradiating the coating area of ​​the decorative painting, the colored paint will absorb part of the incident light, so that the reflected light intensity is reduced, that is, the current of the ranging circuit is reduced. According to the sizes of several ranging circuit currents, the position of the current value mutation is determined, that is, the width of the blank area of ​​the painting. According to this size, the clamping position of the winding component is automatically adjusted to ensure the winding quality.

[0013] Furthermore, the winding assembly includes an adjusting cylinder, a rotating seat and a pressing block. The adjusting cylinders are respectively provided on both sides of the conveyor belt. The adjusting cylinders are tightly connected to the packing table. A sliding seat is provided at the output end of the adjusting cylinder. The sliding seat is slidably connected to the packing table. A rotating groove is provided on the sliding seat. A winding motor is provided in the rotating groove. The output end of the winding motor is tightly connected to the rotating seat. The rotating seat is rotatably connected to the rotating groove. A guide groove is provided on the sliding seat. The pressing block is movably connected to the guide groove.

[0014] The pressing block includes a metal layer and a rubber layer. A pressing surface is provided on the rotating seat. The rubber layer of the pressing block presses the decorative painting on the pressing surface. A limit groove is provided on the side of the rotating seat close to the winding motor. A limit electromagnet is provided in the limit groove, and the limit electromagnet faces the metal layer of the pressing block.

[0015] The adjusting cylinder is installed and fixed through the packing table. The adjusting cylinder is used to output linear displacement and drive the slide to move. The slide is used to fix the winding motor and guide the rotating seat to rotate through the rotating groove. In the initial state, the pressing surface of the pressing block and the rotating seat are separated, and the pressing block is pressed on the upper surface of the decorative painting. The decorative painting moves forward under the action of the suction cup and the conveyor belt, thereby driving the decorative painting to move forward. When approaching the rotating seat, the part of the rotating seat used for winding can be made of metal material, and the remaining part is made of non-metallic material, and a limit groove is set for installing the limit electromagnet. The contact friction between the rubber layer and the decorative painting is greater than the friction between the decorative painting and the pressing surface, pushing the pressing blocks on both sides to move up along the pressing surface, and the pressing blocks are assisted by the limit electromagnet to adsorb, so that the pressing block and the rotating seat form a complete cylinder, and the decorative painting is pressed tightly, so that the winding motor can drive the rotating seat and the pressing block to rotate, and the decorative painting is automatically wound, thereby improving the packaging efficiency. After the rolling is completed, the rolled decorative painting is directly clamped by the transfer robot, and then the decorative painting is cut by the cutting device. After the cutting is completed, the transfer robot puts the rolled decorative painting into the subsequent packaging process to complete the packaging.

[0016] Further, the regulating cylinder is electrically connected to the distance measuring circuit.

[0017] According to the blank area of ​​the decorative painting detected by the distance measuring circuit, the output displacement of the adjusting cylinder is automatically controlled, thereby adjusting the size of the clamping area of ​​the decorative painting to avoid damaging the coating area of ​​the decorative painting.

[0018] Furthermore, the initial end of the negative pressure flow channel coincides with the initial end of the feeding direction, and the terminal end of the negative pressure flow channel and the pressing stations of the pressing block and the rotating seat are arranged in sequence along the feeding direction.

[0019] The initial section of the negative pressure flow channel coincides with the initial position of the conveyor belt feeding stroke, the negative pressure flow channel and the negative pressure pipe are connected to maintain a low pressure state, and the end does not reach the pressing station, that is, when the decorative painting passes the end of the negative pressure flow channel, the suction cup here is no longer connected to the negative pressure flow channel, that is, the decorative painting here is no longer adsorbed, which is convenient for driving the pressing block to move upward and crimping the end of the decorative painting, thereby facilitating winding.

[0020] Furthermore, the cutting device includes a cutting blade and a lifting cylinder, the lifting cylinder is tightly connected to the packing table, the output end of the lifting cylinder is tightly connected to the cutting blade, and the lifting cylinder is electrically connected to the distance measuring circuit;

[0021] When cutting: the distance measuring circuit is in full conduction state.

[0022] By setting the lifting cylinder to provide linear displacement, the cutting knife is driven to move. When the winding is completed, that is, the decorative painting is finished here, the emitted light source no longer irradiates the coating area of ​​the decorative painting, the pigment cannot attenuate the light intensity, the ranging circuit is in a fully conductive state, the current value tends to be the same, the lifting cylinder outputs displacement, and the decorative painting is automatically cut by the cutting knife, which improves the efficiency of automated production without setting additional data. After the cutting is completed, the rolled decorative painting is taken away by the transfer robot. At this time, the crimping surface maintains the initial tilt state, and the limit electromagnet is powered off, so that the pressing block can return to its initial state for continuous packaging.

[0023] As an optimization, the cutting position of the cutting knife is located between the end of the negative pressure flow channel and the pressing station. Since the pressing station needs to roll up the decorative painting through the rotating seat, the relative position is higher, thus forming a slope between the end of the negative pressure flow channel and the pressing station. The decorative painting is cut within this slope to avoid damaging the conveyor belt. At the same time, in order to ensure cutting efficiency, a mounting block with a cutting groove can be set at the end of the cutting and fixed by a packaging table.

[0024] As an optimization, the cutting knife is arranged at an angle, and the moving direction of the cutting knife is perpendicular to the surface of the decorative painting at the cutting position. By arranging the cutting knife at an angle, the cutting efficiency of the decorative painting is improved.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the suction cup is intermittently connected to the negative pressure flow channel within the conveying stroke, that is, the conductive state is maintained during the front-end conveying process, and the decorative painting is driven forward by negative pressure adsorption; when it moves to the end, the suction cup at the end is no longer connected to the negative pressure flow channel through the set length difference, which is convenient for automatically winding up the decorative painting through the winding component, and the blank areas on both sides of the decorative painting are identified through the positioning component to prevent damage to the coating area of ​​the decorative painting; an outgoing light source is set, and when it is irradiated on the coating area of ​​the decorative painting, the colored paint will absorb part of the incident light, so that the reflected light intensity is reduced, that is, the current of the ranging circuit is reduced, and according to a number of ranging The size of the circuit current determines the position of the sudden change of the current value, that is, the width of the blank area of ​​the painting. The clamping position of the winding component is automatically adjusted according to this size to ensure the quality of winding; the decorative painting moves forward under the action of the suction cup and the conveyor belt, thereby driving the decorative painting forward. When it is close to the revolving seat, the contact friction between the rubber layer and the decorative painting is greater than the friction between the decorative painting and the crimping surface, pushing the pressure blocks on both sides to move up along the crimping surface, and assisting the pressure blocks to be adsorbed by the limiting electromagnet, so that the pressure blocks and the revolving seat form a complete cylinder and press the decorative painting, so that the rewinding motor can drive the revolving seat and the pressure blocks to rotate, automatically rewind the decorative painting, and improve packaging efficiency.

[0037] The packing table 1 is used as the main installation base for installing other devices. The power device 2 is used as the main power source for conveying the decorative paintings and automatically rolling them up for packing. After the rolling is completed, the cutting device 3 automatically cuts them to form a series of decorative paintings. A transfer robot is set at the end of the conveying stroke to put the rolled decorative paintings into the packing box to complete the packaging.

[0038] Furthermore, a material guide trough 11 is provided on the packaging table 1, and the power device 2 includes a conveyor belt 21, a winding assembly 22 and a positioning assembly 23. The conveyor belt 21 is arranged along the material guide trough 11, and two power rollers are arranged on the inner circle of the conveyor belt 21. A plurality of fixed grooves 211 are provided on both sides of the conveyor belt 21 along the feeding direction, and suction cups 24 are provided in the fixed grooves 211. A negative pressure flow channel 12 is provided on the packaging table 1, and the suction cup 24 and the negative pressure flow channel 12 are intermittently connected. The upper end of the suction cup 24 faces the decorative painting, and the length of the negative pressure flow channel 12 is smaller than the feeding stroke of the material guide trough 11. The positioning assembly 23 and the winding assembly 22 are arranged in sequence along the feeding direction.

[0039] The conveyor belt 21 is guided by the material guide groove 11, and the power roller has a built-in power motor to drive the outer roller to rotate, thereby driving the conveyor belt 21 to make a rotary motion. The conveyor belt 21 fixes the suction cups 24 respectively through a number of fixed grooves 211 on both sides. The suction cups 24 are intermittently connected to the negative pressure channel 12 within the conveying stroke, that is, the conductive state is maintained during the front-end conveying process, and the decorative painting is driven forward by negative pressure adsorption; when it moves to the end, the suction cup 24 at the end is no longer connected to the negative pressure channel 12 due to the set length difference, so that the decorative painting is automatically reeled in by the reeling component 22, and the blank areas on both sides of the decorative painting are identified by the positioning component 23 to prevent damage to the coating area of ​​the decorative painting and affect the quality of the painting.

[0040] Furthermore, the positioning component 23 includes a support plate 231, an emergent light source 232 and a photosensitive layer 233. There are two support plates 231, and the two support plates 231 are respectively fastened to the packaging table 1, and the two support plates 231 are respectively located on both sides of the feeding direction. The support plate 231 is provided with an emergent light source 232, and the emergent light source 232 faces the surface of the decorative painting. The support plate 231 is provided with a plurality of photosensitive layers 233, and the plurality of photosensitive layers 233 are horizontally arranged perpendicular to the feeding direction. Two electrodes 234 are provided on each photosensitive layer 233, and the two electrodes 234 on the same photosensitive layer 233 are respectively electrically connected to the two wiring terminals of the power supply to form a ranging circuit, and the photosensitive layer 233 is located on the reflected light path of the emergent light source 232.

[0041] By setting the output light source 232, an inclined arrangement can be adopted. After irradiating the decorative painting, a reflected light path is formed, and irradiating the photosensitive layer 233, electron-hole pairs are excited, and the ranging circuit composed of the two electrodes 234 and the power supply is turned on. The greater the light intensity, the greater the current of the ranging circuit. When irradiating the coating area of ​​the decorative painting, the colored paint will absorb part of the incident light, so that the reflected light intensity is reduced, that is, the current of the ranging circuit is reduced. According to the sizes of several ranging circuit currents, the position of the current value mutation is determined, that is, the width of the blank area of ​​the painting, and the clamping position of the winding component 22 is automatically adjusted according to this size to ensure the winding quality.

[0042] Further, the winding assembly 22 includes an adjusting cylinder 221, a rotating seat 224 and a pressing block 225. The adjusting cylinders 221 are respectively provided on both sides of the conveyor belt 21. The adjusting cylinder 221 is tightly connected to the packing table 1. A slide 222 is provided at the output end of the adjusting cylinder 221. The slide 222 is slidably connected to the packing table 1. A rotating groove 2221 is provided on the slide 222. A winding motor 223 is provided in the rotating groove 2221. The output end of the winding motor 223 is tightly connected to the rotating seat 224. The rotating seat 224 is rotatably connected to the rotating groove 2221. A guide groove 2222 is provided on the slide 222. The pressing block 225 is movably connected to the guide groove 2222.

[0043] The pressing block 225 includes a metal layer and a rubber layer. A crimping surface 2241 is provided on the rotating seat 224. The rubber layer of the pressing block 225 presses the decorative painting on the crimping surface 2241. A limiting groove 2242 is provided on the side of the rotating seat 224 close to the winding motor 223. A limiting electromagnet 226 is provided in the limiting groove 2242. The limiting electromagnet 226 faces the metal layer of the pressing block 225.

[0044] The adjusting cylinder 221 is installed and fixed by the packaging table 1. The adjusting cylinder 221 is used to output linear displacement to drive the slide 222 to move. The slide 222 is used to fix the winding motor 223 and to rotationally guide the rotating seat 224 through the rotating groove 2221. In the initial state, the pressing block 225 and the crimping surface 2241 of the rotating seat 224 are separated, and the pressing block 225 is crimped on the upper surface of the decorative painting. The decorative painting moves forward under the action of the suction cup 24 and the conveyor belt 21, thereby driving the decorative painting forward. When it is close to the rotating seat 224, the part of the rotating seat 224 used for winding can be made of metal material, and the remaining part is made of non-metallic material, and a limiting groove 2242 is provided for installing the limiting electromagnet 226. The contact friction between the rubber layer and the decorative painting is greater than the friction between the decorative painting and the crimping surface 2241, pushing the pressing blocks 225 on both sides to move up along the crimping surface 2241, and the limiting electromagnet 226 assists in adsorbing the pressing block 225, so that the pressing block 225 and the rotating seat 224 form a complete cylinder and press the decorative painting, so that the winding motor 223 can drive the rotating seat 224 and the pressing block 225 to rotate, and automatically wind the decorative painting, thereby improving the packaging efficiency. After the rolling is completed, the rolled decorative painting is directly clamped by the transfer robot, and then the decorative painting is cut by the cutting device 3. After the cutting is completed, the transfer robot puts the rolled decorative painting into the subsequent packaging process to complete the packaging.

[0045] Furthermore, the adjusting cylinder 221 is electrically connected to the distance measuring circuit.

[0046] According to the blank area of ​​the decorative painting detected by the distance measuring circuit, the output displacement of the adjustment cylinder 221 is automatically controlled, thereby adjusting the size of the clamping area of ​​the decorative painting to avoid damaging the coating area of ​​the decorative painting.

[0047] Furthermore, the initial end of the negative pressure channel 12 coincides with the initial end of the feeding direction, and the terminal end of the negative pressure channel 12 and the pressing stations of the pressing block 225 and the rotating seat 224 are arranged in sequence along the feeding direction.

[0048] The initial section of the negative pressure flow channel 12 coincides with the initial position of the feeding stroke of the conveyor belt 21. The negative pressure flow channel 12 is connected to the negative pressure tube to maintain a low pressure state, and the end has not reached the pressing station, that is, when the decorative painting passes the end of the negative pressure flow channel 12, the suction cup 24 here is no longer connected to the negative pressure flow channel, that is, it no longer adsorbs the decorative painting here, which is convenient for driving the pressing block 225 to move upward and crimp the end of the decorative painting, thereby facilitating winding.

[0049] Furthermore, the cutting device 3 includes a cutting blade 31 and a lifting cylinder 32, the lifting cylinder 32 is firmly connected to the packing table 1, the output end of the lifting cylinder 32 is firmly connected to the cutting blade 31, and the lifting cylinder 32 is electrically connected to the distance measuring circuit;

[0050] When cutting: the distance measuring circuit is in full conduction state.

[0051] By setting the lifting cylinder 32 to provide linear displacement, the cutting knife 31 is driven to move. When the winding is completed, that is, the decorative painting is finished here, the emitted light source 232 no longer irradiates the coating area of ​​the decorative painting, the pigment cannot attenuate the light intensity, the ranging circuit is in a fully conductive state, the current value tends to be the same, the lifting cylinder 32 outputs displacement, and the decorative painting is automatically cut by the cutting knife 31, thereby improving the efficiency of automated production without setting additional data. After the cutting is completed, the rolled decorative painting is taken away by the transfer robot. At this time, the crimping surface 2241 maintains the initial tilt state, the limit electromagnet 226 is powered off, and the pressing block 225 automatically slides down. By setting auxiliary equipment, the pressing block 225 is placed on the decorative painting, which is convenient for the pressing block 225 to restore its initial state for continuous packaging.

[0052] As an optimization, the cutting position of the cutting knife 31 is located between the end of the negative pressure flow channel 12 and the pressing station. Since the pressing station needs to roll up the decorative painting through the rotating seat 224, the relative position is relatively high, so a slope is formed between the end of the negative pressure flow channel 12 and the pressing station, and the decorative painting is cut within this slope to avoid damaging the conveyor belt 21. At the same time, in order to ensure cutting efficiency, a mounting block with a cutting groove can be set at the end of the cutting and fixed by the packaging table 1.

[0053] As an optimization, the cutting blade 31 is arranged obliquely, and the moving direction of the cutting blade 31 is perpendicular to the surface of the decorative painting at the cutting position. By arranging the cutting blade 31 obliquely, the cutting efficiency of the decorative painting is improved.

[0054] The working principle of the present invention is as follows: the suction cup 24 is intermittently connected to the negative pressure flow channel 12 within the conveying stroke, that is, during the front-end conveying process, the conductive state is maintained, and the decorative painting is driven forward by negative pressure adsorption; when it moves to the end, the suction cup 24 at the end is no longer connected to the negative pressure flow channel 12 due to the set length difference, so that the decorative painting can be automatically reeled in by the reeling component 22, and the blank areas on both sides of the decorative painting can be identified by the positioning component 23 to prevent damage to the coating area of ​​the decorative painting; an output light source 232 is set, and when it is irradiated on the coating area of ​​the decorative painting, the colored paint will absorb part of the incident light, so that the reflected light intensity is reduced, that is, the current of the ranging circuit is reduced, and the position of the current value mutation is determined according to the magnitude of the current of several ranging circuits. , that is, the width of the blank area of ​​the painting, and automatically adjusts the clamping position of the winding component 22 according to this size to ensure the winding quality; the decorative painting moves forward under the action of the suction cup 24 and the conveyor belt 21, thereby driving the decorative painting forward. When approaching the rotating seat 224, the contact friction between the rubber layer and the decorative painting is greater than the friction between the decorative painting and the crimping surface 2241, pushing the pressing blocks 225 on both sides to move up along the crimping surface 2241, and the limiting electromagnet 226 assists in adsorbing the pressing blocks 225, so that the pressing blocks 225 and the rotating seat 224 form a complete cylinder and press the decorative painting, so that the winding motor 223 can drive the rotating seat 224 and the pressing blocks 225 to rotate, and automatically wind the decorative painting, thereby improving the packaging efficiency.
