Description

Technical Field

[0001] The present application relates to the field of gluing equipment, and in particular to a roll material fixed-distance cutting device. Background Art

[0002] Leather is a denatured, non-perishable animal hide obtained through physical and chemical processes such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three dimensions. Its surface features a unique grain layer, resulting in a natural texture, sheen, and pleasant feel. To enhance the leather's lifespan and quality, it is typically coated with glue. Gluing involves applying a coating (including solvent-based, latex, and water-based) to the fabric surface using a coating machine.

[0003] In the prior art, common gluing equipment primarily consists of a frame, on which are mounted an unwinding mechanism, a tension control mechanism, a rewinding mechanism, a gluing mechanism, and a cooling and drying mechanism. The unwinding mechanism unwinds the raw material coil at a constant speed. The coil is then driven by the tension control mechanism and passes through the gluing mechanism. After the coated coil is delivered by the gluing mechanism, the cooling and drying mechanism cools the coil to dry the adhesive on the coil surface. The dried coil is then rewound by the rewinding mechanism.

[0004] However, the existing gluing equipment can only be stored through a winding mechanism after completing the gluing process. If the roll material that has completed the gluing process needs to be cut into sheets of the required length, the roll material needs to be transported to the cutting mechanism for cutting, which is relatively cumbersome and has low usability, and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience for operators to use gluing equipment, the present application provides a roll material fixed-distance cutting device.

[0006] The present application provides a device for cutting coils at fixed distances using the following technical solutions:

[0007] A device for cutting coiled material at a fixed distance comprises a frame, an upper knife, a lower knife, a feeding mechanism and a discharging channel are mounted on the frame, the lower knife is fixedly mounted on the frame, the upper knife is movably mounted on the frame, the upper knife is mounted above the lower knife, and a feeding port is formed between the upper knife and the lower knife;

[0008] The feeding mechanism is located on a side of the upper knife and the lower knife close to the cooling and drying mechanism, and the discharging channel is located on a side of the upper knife and the lower knife away from the cooling and drying mechanism; and:

[0009] a detection control module, configured to detect the length of the coil fed through the feed port and output a drive control signal when the coil length reaches a set length or an integral multiple of the set length;

[0010] The driving mechanism is fixedly mounted on the frame, and the driving end is fixedly connected to the upper knife, and is used for receiving the driving control signal and driving the upper knife to move in a direction close to the lower knife.

[0011] By adopting the above technical solution, during the actual production and processing process, the feeding mechanism will continuously transport the coiled material that has been coated with glue and dried between the upper knife and the lower knife. During this process, the detection and control module will detect the length of the coiled material passing through the material outlet in real time. When the length of the coiled material reaches the set length or an integer multiple of the set length, the detection and control module will automatically control the driving mechanism to drive the upper knife to move in the direction close to the lower knife to complete the cutting operation of the coiled material. The cut sheets will be sent out through the discharge channel, which can achieve the technical effects of automatic feeding and automatic fixed-distance cutting, and can effectively improve the convenience of operators in using the gluing equipment.

[0012] Preferably, the feeding mechanism includes a traction steel roller and a rubber pressure roller, two fixed seats are fixedly installed on the frame, two ends of the traction roller are respectively rotatably installed on the two fixed seats, sliding seats are respectively slidably installed on the two fixed seats, two ends of the rubber pressure roller are respectively rotatably installed on the two sliding seats, the two fixed seats are respectively fixedly installed with a first cylinder, and the cylinder shaft of the first cylinder is respectively fixedly connected to the two sliding seats;

[0013] A servo motor is fixedly mounted on the frame, and a driving end of the servo motor is connected to a driving pulley via a coupling. A mounting shaft at one end of the traction steel roller extends out of the fixed seat, and a driven pulley is fixedly mounted on the end of the traction steel roller extending out of the fixed seat. A transmission belt is sleeved on the driving pulley and the driven pulley.

[0014] By adopting the above technical solution, when the cutting device is in use, the two first cylinders simultaneously extend their cylinder shafts, causing the two sliding seats to move downward until the roller surface of the rubber pressure roller contacts the top of the coiled material. The servo motor drives the traction steel roller to rotate via the drive pulley, transmission belt, and driven pulley. The rubber pressure roller rotates in the same direction as the traction steel roller due to friction, continuously conveying the coiled material between the upper and lower knives, achieving the technical effect of continuous material feeding. When the gluing equipment does not need to cut pieces, the first cylinder drives the rubber pressure roller to reset, and the servo motor stops driving the traction steel roller, facilitating the continuous conveyance of the coiled material to the winding mechanism.

[0015] Preferably, the detection control module includes:

[0016] A sensing slot is provided on the end surface of the rubber pressure roller;

[0017] an infrared distance measuring sensor, fixedly mounted on the sliding seat, with its sensing end facing the end surface of the rubber pressure roller, for detecting the sensing slot and outputting a sensing signal;

[0018] The single chip microcomputer is connected to the infrared ranging sensor and the signal output end of the control panel, and is used to receive the sensing signal and calculate the length of the coil sent through the discharge port, and output the drive control signal when the coil length reaches a set length or an integer multiple of the set length.

[0019] By adopting the above technical solution, since the length of the roll material sent out corresponding to one rotation of the rubber pressure roller is a fixed length, the infrared ranging sensor, the sensing slot and the single-chip computer are used in combination with each other. The technical effect of automatically detecting the length of the roll material and automatically controlling the fixed-distance cutting of the upper knife piece can be achieved by detecting the number of rotations of the rubber pressure roller.

[0020] Preferably, the driving mechanism includes two second cylinders, a mounting beam is fixedly installed between the two fixed seats, the cylinder bodies of the two second cylinders are fixedly installed on the two mounting beams, the cylinder shafts of the two second cylinders are fixedly connected to the upper knife, and the two second cylinders drive the upper knife to move toward or away from the lower knife.

[0021] By adopting the above technical solution, the two second cylinders extend or retract the cylinder shafts to drive the upper knife to move toward or away from the lower knife.

[0022] Preferably, two opposite connecting seats are fixedly installed on the bottom of the mounting crossbeam, a first mounting seat is slidably installed between the two connecting seats, and the upper knife is fixedly installed on the first mounting seat;

[0023] Slide blocks are fixedly mounted on both ends of the first mounting seat, guide rails are fixedly mounted on the inner sides of the two connecting seats, and sliding grooves adapted to the guide rails are respectively provided on the two slide blocks.

[0024] By adopting the above technical solution, the slider and the guide rail are used in combination with each other to limit the sliding trajectory of the first mounting seat, reduce the occurrence of position offset of the first mounting seat, and ensure the accuracy of the knife-lifting and knife-dropping actions.

[0025] Preferably, a first support plate and a second support plate are fixedly mounted on the frame, the first support plate is mounted above the second support plate, and a channel for delivering the coil is formed between the first support plate and the second support plate.

[0026] By adopting the above technical solution, the coiled material is sent out through the channel between the first support plate and the second support plate and then sent into the material transfer port between the upper knife and the lower knife, so that the coiled material can be transported smoothly between the upper knife and the lower knife, thereby ensuring the flatness of the cut of the cut piece.

[0027] Preferably, the discharge channel is arranged to be inclined downward along the direction in which the coil is delivered.

[0028] By adopting the above technical solution, the discharging channel is arranged to be inclined downward, so that the sheet can slide out easily after the upper knife finishes cutting.

[0029] In summary, the present invention provides a device for cutting coiled material at a fixed distance, which has at least one of the following beneficial technical effects:

[0030] 1. During the actual production process, the feeding mechanism continuously conveys the glued and dried coiled material between the upper and lower blades. During this process, the detection and control module detects the length of the coiled material passing through the feed port in real time. When the coiled material length reaches the set length or an integer multiple of the set length, the detection and control module automatically controls the drive mechanism to drive the upper blade toward the lower blade to complete the cutting operation of the coiled material. The cut sheets are sent out through the discharge channel, achieving the technical effects of automatic feeding and automatic distance cutting, which can effectively improve the convenience of the operator in using the gluing equipment;

[0031] 2. The slider and the guide rail are used in conjunction with each other to limit the sliding trajectory of the first mounting seat, reduce the occurrence of position deviation of the first mounting seat, and ensure the accuracy of the knife loading and unloading actions.

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] Example

[0040] The embodiment of the present application discloses a device for cutting coiled material at a fixed distance. Figure 1-5 It mainly includes a frame 1, on which an upper knife 2, a lower knife 3, a feeding mechanism 4 and a discharging channel 5 are installed. The lower knife 3 is fixedly installed on the frame 1, and the upper knife 2 can be lifted and lowered on the frame 1. The upper knife 2 is mounted above the lower knife 3, and a feeding port is formed between the upper knife 2 and the lower knife 3; the feeding mechanism 4 is located on the side of the upper knife 2 and the lower knife 3 close to the cooling and drying mechanism, and the discharging channel 5 is located on the side of the upper knife 2 and the lower knife 3 away from the cooling and drying mechanism; and: a detection control module 6, which is used to detect the length of the coil sent out through the feeding port and output a drive control signal when the coil length reaches a set length or an integer multiple of the set length; a driving mechanism 7, which is fixedly installed on the frame 1, and the driving end is fixedly connected to the upper knife 2, and is used to receive the drive control signal and drive the upper knife 2 to move toward the direction close to the lower knife 3.

[0041] During the actual production and processing process, the feeding mechanism continuously transports the coiled material after gluing and drying between the upper knife 2 and the lower knife 3. During this process, the detection control module 6 detects the length of the coiled material passing through the material port in real time. When the length of the coiled material reaches the set length or an integer multiple of the set length, the detection control module 6 automatically controls the driving mechanism 7 to drive the upper knife 2 to move toward the lower knife 3 to complete the cutting operation of the coiled material. The cut sheet is sent out through the discharge channel 5, which can achieve the technical effects of automatic feeding and automatic fixed-distance cutting, and can effectively improve the convenience of operators in using the gluing equipment.

[0042] Reference Figure 2 and Figure 3The feeding mechanism 4 includes a traction steel roller 41 and a rubber pressure roller 42. Two fixed seats 11 are fixedly installed on the frame 1. The two ends of the traction roller are rotatably installed on the two fixed seats 11. The two fixed seats 11 are slidably installed with sliding seats 12. The two ends of the rubber pressure roller 42 are rotatably installed on the two sliding seats 12. The two fixed seats 11 are respectively fixedly installed with first cylinders 43, and the cylinder shafts of the first cylinders 43 are respectively fixedly connected to the two sliding seats 12; a servo motor 44 is fixedly installed on the frame 1, and the driving end of the servo motor 44 is connected to a driving pulley 45 through a coupling. The mounting shaft at one end of the traction steel roller 41 extends out of the fixed seat 11, and a driven pulley 46 is fixedly installed on the end of the traction steel roller 41 extending out of the fixed seat 11. A transmission belt 47 is provided on the driving pulley 45 and the driven pulley 46.

[0043] When the cutting device is in use, the two first air cylinders 43 simultaneously extend their cylinder shafts, causing the two sliding seats 12 to move downward until the roller surface of the rubber pressure roller 42 contacts the top of the coiled material. The servo motor 44 drives the traction steel roller 41 to rotate via the drive pulley 45, transmission belt 47, and driven pulley 46. The rubber pressure roller 42 rotates in the same direction as the traction steel roller 41 due to friction, continuously conveying the coiled material between the upper knife 2 and the lower knife 3, achieving the technical effect of continuous feeding. When the gluing equipment does not need to cut pieces, the first air cylinder 43 drives the rubber pressure roller 42 to reset, and the servo motor 44 stops driving the traction steel roller 41, facilitating the continuous conveyance of the coiled material to the winding mechanism.

[0044] Reference Figure 5 The detection control module 6 includes: a sensing slot 61 provided on the end surface of the rubber pressure roller 42; an infrared distance sensor 62, fixedly mounted on the sliding seat 12, with the sensing end facing the end surface of the rubber pressure roller 42, for detecting the sensing slot 61 and outputting a sensing signal; a single chip microcomputer, connected to the infrared distance sensor 62 and the signal output end of the control panel, for receiving the sensing signal and calculating the length of the roll delivered through the discharge port, and outputting a drive control signal when the roll length reaches a set length or an integer multiple of the set length.

[0045] Since the length of the roll material sent out corresponding to one rotation of the rubber pressure roller 42 is a fixed length, the infrared ranging sensor 62, the sensing slot 61 and the single-chip microcomputer are used in conjunction with each other. The number of rotations of the rubber pressure roller 42 can be detected to achieve the technical effect of automatically detecting the length of the roll material and automatically controlling the upper knife 2 to cut the pieces at a fixed distance.

[0046] Reference Figure 2 and Figure 3The driving mechanism 7 includes two second cylinders 71, a mounting beam 72 is fixedly installed between the two fixed seats 11, the cylinder bodies of the two second cylinders 71 are fixedly installed on the two mounting beams 72, and the cylinder shafts of the two second cylinders 71 are fixedly connected to the upper knife 2. The two second cylinders 71 drive the upper knife 2 to move toward or away from the lower knife 3.

[0047] The two second cylinders 71 extend or retract the cylinder shafts to drive the upper knife 2 to move toward or away from the lower knife 3.

[0048] Reference Figure 2 、 Figure 3 as well as Figure 4 Two opposing connecting seats 75 are fixedly installed at the bottom of the mounting beam 72, and a first mounting seat 73 is slidably installed between the two connecting seats 75. The upper knife 2 is fixedly installed on the first mounting seat 73, the second mounting seat 74 is fixedly installed on the frame 1, and the lower knife 3 is fixedly installed on the second mounting seat 74; sliders 77 are fixedly installed at both ends of the first mounting seat 73, and guide rails 76 are fixedly installed on the inner sides of the two connecting seats 75, and the two sliders 77 are respectively provided with sliding grooves adapted to the guide rails 76.

[0049] The slider 77 and the guide rail 76 are used in conjunction with each other to limit the sliding trajectory of the first mounting seat 73, reduce the occurrence of position deviation of the first mounting seat 73, and ensure the accuracy of the upper knife 2's knife-dropping action.

[0050] Reference Figure 4 A first support plate 13 and a second support plate 14 are fixedly mounted on the frame 1. The first support plate 13 is mounted above the second support plate 14. A channel for delivering the coil is formed between the first support plate 13 and the second support plate 14.

[0051] The coiled material is sent out through the channel between the first support plate 13 and the second support plate 14 and then sent into the feed port between the upper knife 2 and the lower knife 3, so that the coiled material can be smoothly transported between the upper knife 2 and the lower knife 3, thereby ensuring the flatness of the cut edge.

[0052] Reference Figure 2 The discharging channel 5 is arranged obliquely downward along the direction in which the coil is fed. The discharging channel 5 is arranged obliquely downward, so that the sheet can slide off after the upper knife 2 has finished cutting.

[0053] The implementation principle of a coil material fixed-distance cutting device in an embodiment of the present application is as follows: during the actual production and processing process, the feeding mechanism continuously transports the coil material that has been coated with glue and dried through the upper knife 2 and the lower knife 3. During this process, the detection control module 6 detects the length of the coil material passing through the material outlet in real time. When the length of the coil material reaches the set length or an integer multiple of the set length, the detection control module 6 automatically controls the driving mechanism 7 to drive the upper knife 2 to move toward the direction close to the lower knife 3, completing the cutting operation of the coil material. The cut sheet is sent out through the discharge channel 5, which can achieve the technical effects of automatic feeding and automatic fixed-distance cutting, and can effectively improve the convenience of the operator in using the gluing equipment.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
