Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically a straight blade cutting machine. Background Technology

[0002] Straight blade cutting machines are commonly used cutting equipment, widely applied in the cutting and processing of materials such as clothing, leather, paper, and fabric. The main characteristic of straight blade cutting machines is that they use straight blades for cutting, offering advantages such as high cutting speed, good cutting results, and simple operation.

[0003] For example, the national authorized patent announcement number CN219294152U discloses a cutting structure for a cutting machine, including a worktable. A vertical support rod is set on one side of the top of the worktable, and a first motor is set on the top of the horizontal support frame. A telescopic rod is installed at the output end of the first motor. A fixed base is set at one end of the telescopic rod, and a cutting structure is set at one end of the fixed base. A second motor is installed on one side wall of the worktable. A vacuum cleaner is set at the bottom of the cleaning roller, and a waste collection box is set at the bottom of the vacuum cleaner to prevent the cutting machine from generating waste or dust during the cutting process, which could contaminate the material to be cut or block the cutting opening and cause the equipment to malfunction. A U-shaped plate is set on the top of the worktable, and screws are set inside both sides of the U-shaped frame. A pressing plate is set at the bottom of the fixed plate to prevent the material to be cut from being pulled and causing blockage when the cutting machine is feeding.

[0004] However, the cutting structure of the cutting machine mentioned above cannot set the length of the object so that the cutting blade can automatically recognize and cut it. This requires the staff to pay attention to the cutting progress at all times, manually measure or judge the cutting position based on experience, and then manually control the cutting action. This greatly increases the time and effort cost of manual operation and reduces the overall cutting efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a straight blade cutting machine to solve the problem mentioned in the background art that the length of the object cannot be set so that the cutting blade can automatically identify and perform the cutting operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A straight-blade cutting machine includes: a frame, two sets of conveyor belts are driven and installed inside the frame, and drive belts are fitted on the outer surface of the drive columns of the two sets of conveyor belts; a U-shaped frame is fixedly installed on the upper surface of the frame, and a hydraulic cylinder is fixedly installed on the upper surface of the U-shaped frame; a cutter is fixedly installed at one end of the piston rod of the hydraulic cylinder, and the cutter is staggered with the frame so that the cutter can cut the objects conveyed by the conveyor belts; a guide frame is fixedly installed on the upper surface of one end of the frame, and a cutting length positioning mechanism is slidably installed in the guide frame.

[0008] Preferably, guide cylinders are fixedly installed at both ends of the cutter, the guide cylinders are slidably installed on the outer surface of the slide column, and the slide column is fixedly installed between the frame and the U-shaped frame.

[0009] Preferably, the cutting length positioning mechanism includes a laser sensor, a collar is fixedly installed on the outer surface of the laser sensor, the laser sensor is slidably installed in the guide frame through the collar, the signal transmitting end of the laser sensor is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the hydraulic cylinder solenoid valve and the conveyor belt drive motor.

[0010] Preferably, the laser sensor and controller are model numbers E3NC-S and E3NC-SA, respectively.

[0011] Preferably, a connecting pipe is fixedly installed on the upper end of the outer surface of the collar, the connecting pipe slides out from the upper surface of the guide frame, a lifting rod is slidably installed inside the connecting pipe, a top pressure ring is fixedly installed on the outer surface of the lifting rod and slides on the outer surface of the connecting pipe, and the top pressure ring slides out from the outer surface of the connecting pipe.

[0012] Preferably, a cover is fixedly installed on the outer surface of the connecting tube, and a spring is fitted on the outer surface of the connecting tube. The upper and lower ends of the spring respectively abut against the lower inner surface of the cover and the upper surface of the pressure ring, so that the spring can push the pressure ring to abut against the upper surface of the guide frame to lock the sliding of the laser sensor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the frame, U-shaped frame, hydraulic cylinder, cutter, conveyor belt, guide frame, and cutting length positioning mechanism, when cutting an object, the operator can push the cutting length positioning mechanism within the guide frame to slide according to the required cutting length until the cutting length positioning mechanism slides to the required distance from the cutter, at which point it stops. The operator can then place the object to be cut on the surface of the conveyor belt and transport it past the cutter. When the object is flush with the cutting length positioning mechanism, it is detected and a detection signal is sent to the controller. The controller then stops the conveyor belt drive motor and simultaneously starts the hydraulic cylinder to push the cutter in a reciprocating motion of cutting and lifting. After cutting, the controller can restart the conveyor belt drive motor to continue transporting the object. The cut object will remain covered by the cutting length positioning mechanism after cutting. At one end of the length positioning mechanism, to prevent the hydraulic cylinder from being activated by misjudgment during the cutting length positioning mechanism, a time judgment logic is set in the controller system. When the cutting length positioning mechanism detects an object and performs cutting, and then detects an object again, it does not immediately activate the hydraulic cylinder, but waits for a specific period of time to allow the cut object to be picked up by the worker. After the waiting time has passed, the cutting length positioning mechanism will resume detection to re-detect the uncut object. This enables the setting of the object's length for automatic identification and cutting operation, eliminating the need for frequent manual control of the cutting action. From object conveying, detection, cutting, and subsequent conveying, the entire process forms a relatively complete automated workflow, reducing manual intervention, lowering the time and effort costs of manual operation, and increasing overall cutting efficiency.

[0015] 2. Through the design of the laser sensor, collar, connecting tube, lifting rod, top pressure ring, and spring, when cutting objects, the operator can pull up the lifting rod according to the required cutting length, causing the top pressure ring to slide on the outer surface of the connecting tube and disengage from the guide frame. During this sliding motion, the top pressure ring also presses against one end of the spring fitted on the outer surface of the connecting tube, thus applying a downward spring force to the top pressure ring. The operator can then squeeze the outer surface of the lifting rod to push and pull the collar, causing the laser sensor to slide back and forth within the guide frame until the distance between the laser sensor and the cutter reaches the required cutting distance. Once the desired length is reached, stop and release the lifting rod. The lifting rod, pushed back into the connecting tube by the spring force applied by the top pressure ring, will then cause the lifting rod to drive the top pressure ring to press against the upper surface of the guide frame, applying a limiting force to the sliding of the laser sensor. This allows for length control of the cut object. The process is simple: just pull up the lifting rod and push and pull the collar to easily move the laser sensor within the guide frame, quickly adjusting the distance between it and the cutter to accommodate the required cutting length for different objects. No complicated tools or cumbersome disassembly and installation operations are required, improving production preparation efficiency and facilitating rapid switching between different production tasks.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-2 As shown, this embodiment provides a straight blade cutting machine, including: a frame 1, two sets of conveyor belts 105 are installed inside the frame 1, and a transmission belt 107 is fitted on the outer surface of the transmission column of the two sets of conveyor belts 105. A U-shaped frame 101 is fixedly installed on the upper surface of the frame 1, and a hydraulic cylinder 102 is fixedly installed on the upper surface of the U-shaped frame 101. A cutter 103 is fixedly installed at one end of the piston rod of the hydraulic cylinder 102. The cutter 103 and the frame 1 are staggered, so that the cutter 103 can cut the objects conveyed by the conveyor belt 105. A guide frame 106 is fixedly installed on the upper surface of one end of the frame 1. A cutting length positioning mechanism 2 is slidably installed in the guide frame 106. Guide cylinders 108 are fixedly installed at both ends of the cutter 103. The guide cylinders 108 are slidably installed on the outer surface of the slide column 104. The slide column 104 is fixedly installed between the frame 1 and the U-shaped frame 101.

[0024] Through the design of frame 1, U-shaped frame 101, hydraulic cylinder 102, cutter 103, conveyor belt 105, guide frame 106, and cutting length positioning mechanism 2, when cutting an object, the operator can push the cutting length positioning mechanism 2 within the guide frame 106 to slide according to the required cutting length until the distance between the cutting length positioning mechanism 2 and the cutter 103 reaches the required length, at which point it stops. Then, the operator can place the object to be cut on the surface of the conveyor belt 105 and transport it past the cutter 103 until it is flush with the cutting length positioning mechanism 2. This will be detected, and a detection signal will be sent to the controller. The controller will then stop the drive motor of the conveyor belt 105 and simultaneously start the hydraulic cylinder 102 to push the cutter 103 for one reciprocating action of cutting and lifting. After cutting, the controller can restart the drive motor of the conveyor belt 105 to continue transporting the object. After cutting, the object being cut will continuously cover one end of the cutting length positioning mechanism 2. To prevent the cutting length positioning mechanism 2 from misjudging and activating the hydraulic cylinder 102, a time judgment logic is set in the controller system. When the cutting length positioning mechanism 2 detects an object and cuts it, and then detects an object again, it does not immediately activate the hydraulic cylinder 102. Instead, it waits for a specific period of time for the object to be picked up by the worker. After the waiting time has passed, the cutting length positioning mechanism 2 will resume its detection work to detect the uncut object again. This allows the length of the object to be set and automatically identified and cut without the need for frequent manual control of the cutting action. From object conveying, detection, cutting, and subsequent conveying, the entire process forms a relatively complete automated process, reducing manual intervention, lowering the time and effort costs of manual operation, and increasing the overall cutting efficiency.

[0025] like Figures 3-5 As shown, the cutting length positioning mechanism 2 includes a laser sensor 201. A collar 202 is fixedly installed on the outer surface of the laser sensor 201. The laser sensor 201 is slidably installed in the guide frame 106 through the collar 202. The signal transmitting end of the laser sensor 201 is connected to the signal receiving end of the controller. The control output end of the controller is electrically connected to the solenoid valve of the hydraulic cylinder 102 and the electrical control end of the drive motor of the conveyor belt 105.

[0026] The laser sensor 201 and the controller are model numbers E3NC-S and E3NC-SA, respectively.

[0027] Among them, a connecting pipe 203 is fixedly installed on the upper end of the outer surface of the collar 202. The connecting pipe 203 slides out from the upper surface of the guide frame 106. A lifting rod 204 is slidably installed inside the connecting pipe 203. A top pressure ring 205 is fixedly installed on the outer surface of the lifting rod 204 and slides on the outer surface of the connecting pipe 203. The top pressure ring 205 slides out from the outer surface of the connecting pipe 203.

[0028] The connecting pipe 203 is fixedly mounted with a cover 207, and a spring 206 is fitted on the outer surface of the connecting pipe 203. The upper and lower ends of the spring 206 respectively abut against the lower inner surface of the cover 207 and the upper surface of the pressure ring 205, so that the spring 206 can push the pressure ring 205 to abut against the upper surface of the guide frame 106 to lock the sliding of the laser sensor 201.

[0029] Through the design of the laser sensor 201, collar 202, connecting tube 203, lifting rod 204, top pressure ring 205, and spring 206, when cutting objects, the operator can pull the lifting rod 204 upwards according to the required cutting length, causing the top pressure ring 205 to slide on the outer surface of the connecting tube 203 and disengage from the guide frame 106. During the sliding of the top pressure ring 205 on the outer surface of the connecting tube 203, it also presses against one end of the spring 206 fitted on the outer surface of the connecting tube 203. This allows the spring 206 to apply a downward spring force to the top pressure ring 205. Then, the operator can squeeze the outer surface of the lifting rod 204 to push and pull the collar 202, causing the laser sensor 201 to slide back and forth within the guide frame 106 until the laser sensor 201 slides to a distance of 10 units from the cutter. Once the required cutting length is achieved, the lifting rod 204 can be stopped and released, allowing it to slide back into the connecting tube 203 through the spring force applied by the top pressure ring 205. This causes the lifting rod 204 to drive the top pressure ring 205 to press against the upper surface of the guide frame 106 again, applying a limiting force to the sliding of the laser sensor 201. This allows for length control of the cut object. The process only requires pulling up the lifting rod 204 and pushing and pulling the collar 202 to easily move the laser sensor 201 within the guide frame 106, quickly adjusting the distance between it and the cutter 103 to adapt to the cutting length required for different objects. This eliminates the need for complex tools or cumbersome disassembly and installation operations, improving production preparation efficiency and facilitating rapid switching between different production tasks.

[0030] Based on the above technical solution, the working steps of this solution are summarized as follows: When cutting the object, the worker can pull up the lifting rod 204 according to the required cutting length, causing the top pressure ring 205 to slide on the outer surface of the connecting tube 203 and disengage from the guide frame 106. During the process of the top pressure ring 205 sliding on the outer surface of the connecting tube 203, it will also press against one end of the spring 206 fitted on the outer surface of the connecting tube 203. This will allow the spring 206 to apply a downward spring force to the top pressure ring 205, which can then be squeezed by the worker on the lifting rod 204. The outer surface of the guide frame 106 pushes and pulls the collar 202 to drive the laser sensor 201 to slide back and forth within the guide frame 106 until the distance between the laser sensor 201 and the cutter 103 reaches the required cutting length. Then, the lifting rod 204 is released, allowing it to slide back into the connecting tube 203 through the spring force applied by the top pressure ring 205. This causes the lifting rod 204 to drive the top pressure ring 205 to again contact the upper surface of the guide frame 106, applying a limiting force to the sliding of the laser sensor 201, thus achieving the cutting... The length of the object is adjusted so that the worker can place the object to be cut on the surface of the conveyor belt 105 and transport it past the cutter 103. When the object is flush with the laser sensor 201, it will be detected and a detection signal will be sent to the controller. The controller will then stop the drive motor of the conveyor belt 105 and simultaneously start the hydraulic cylinder 102 to push the cutter 103 to perform a reciprocating motion of cutting and lifting. After cutting, the controller can restart the drive motor of the conveyor belt 105 to continue transporting the object. After cutting, the cut object will continue to cover one end of the laser sensor 201. In order to prevent the laser sensor 201 from malfunctioning and activating the hydraulic cylinder 102, a time judgment logic is set in the controller system. When the laser sensor 201 detects an object and cuts it, it does not immediately activate the hydraulic cylinder 102 when it detects an object again. Instead, it waits for a specific period of time for the cut object to be picked up by the worker. After the waiting time has passed, the laser sensor 201 will resume detection to detect uncut objects again.

[0031] In summary, this straight-blade cutting machine can automatically identify and cut objects by setting their length, eliminating the need for frequent manual control of the cutting action. From object feeding, detection, cutting, and subsequent feeding, the entire process forms a relatively complete automated workflow, reducing manual intervention, lowering the time and effort costs of manual operation, and increasing overall cutting efficiency.
