Abstract

This invention relates to the field of die-cutting technology, specifically to a fully automatic die-cutting device for the insertion of a plastic guide rail in a film cutter. The device includes a frame, an upper die base and a lower die base on the frame, with a die-cutting blade on the upper die base. A feeding guide rail is also provided on the frame, with a first linear actuator for moving the plastic guide rail. A support guide rail is provided on the lower die base for guiding the movement of the plastic guide rail, and a limiting block is provided on the support guide rail to restrict its movement. This invention achieves precise control of the plastic guide rail's position through the feeding guide rail, the first linear actuator, the support guide rail, and the limiting block.

This solves the problem of inconsistent positional accuracy along the length of the plastic guide rail during feeding.

Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, specifically to a fully automatic die-cutting device for the insertion of a plastic guide rail of a film cutter. Background Technology

[0002] Die-cutting equipment is a type of machinery used in manufacturing for the precise cutting, stamping, and shaping of non-metallic or metallic materials. When die-cutting a workpiece, it is crucial to ensure its positional stability. Any deviation in the workpiece's position can significantly impact die-cutting accuracy, and in severe cases, render the workpiece unsuitable for subsequent assembly.

[0003] To this end, Chinese Patent No. CN116079832B discloses an automated feeding device for die-cutting educational cards. The device can fix the cardboard during die-cutting through a clamping mechanism to prevent the cardboard from shifting and thus reducing product quality. In addition, the device collects the waste generated during cutting to prevent the waste from adversely affecting the cutting of the next cardboard and improves the production environment.

[0004] However, plastic guide rails differ from ordinary flat workpieces; they have a three-dimensional structure. When machining plastic guide rails, to prevent deformation and breakage under pressure, the workpiece cannot be directly clamped and fixed. Furthermore, plastic guide rails are elongated, requiring precise machining along their length. Without fixation, workpiece misalignment during machining is unavoidable, significantly impacting machining quality. Summary of the Invention

[0005] To address the aforementioned issues, a fully automatic die-cutting device for the insertion of plastic guide rails in a film cutter is provided. This device solves the problem of the inability to guarantee the positional accuracy of the plastic guide rail in the length direction during feeding by using a feeding guide rail, a first linear driver, a support guide rail, and a limiting block.

[0008] Preferably, the control mechanism includes a limiting component and a control component; the limiting component is used to limit the movement of the limit block in the vertical direction; the control component is used to release the limiting component from restricting the upward movement of the limit block; when the control component releases the limiting component from restricting the upward movement of the limit block, the limit block moves upward under the elastic force of the gas spring.

[0009] Preferably, the gas spring has an end seat at the end furthest from the connecting rod, and the end seat has a first elastic element connected to the connecting rod; the mounting base has a first bracket, and the first bracket has a guide plate for guiding the lifting and lowering of the end seat; the support guide rail has a contact position and a limiting position, and the limiting block can move between the contact position and the limiting position; when the limiting block is in the contact position, the end seat is squeezed by the guide plate, the gas spring is in a compressed state, and the limiting block has a downward tendency; when the limiting block is in the limiting position, the gas spring is in an extended state, and the limiting block has an upward tendency.

[0010] Preferably, the mounting base has a sliding groove; the mounting base has a slider that slides in cooperation with the sliding groove, and the connecting rod is hinged to the slider; the slider has a second elastic element that is connected to the mounting base.

[0012] Preferably, the control assembly includes a push plate, a guide rod, and a fourth elastic element; the push plate is connected to the guide rod, and the guide rod is slidably mounted on the mounting base in the vertical direction; both ends of the fourth elastic element are connected to the push plate and the mounting base respectively, and the push plate can move up and down in the vertical direction as the fourth elastic element extends and retracts; when the upper die base moves down for die cutting, it pushes the push plate down; the side of the limiting strip near the push plate has an arc surface, and when the push plate moves down, it squeezes the arc surface of the limiting strip and pushes the limiting strip into the receiving groove.

[0013] Preferably, the upper mold base is provided with a main rod and a secondary rod, the main rod is connected to the upper mold base, and the secondary rod is slidably fitted with the main rod; the main rod is provided with a fifth elastic element connected to the secondary rod.

[0014] Preferably, the mounting base is equipped with a contact sensor for detecting the position of the limit block.

[0015] Preferably, the mounting base has a mounting groove for accommodating the connecting rod, and elastic protrusions are provided on both sides of the mounting groove.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention achieves precise control of the position of a plastic guide rail through a feeding guide rail, a first linear driver, a support guide rail, and a limiting block. While the support guide rail guides the movement of the plastic guide rail, the limiting block restricts the movement stroke of the plastic guide rail. The first linear driver pushes the plastic guide rail to feed the material. When the plastic guide rail comes into contact with the limiting block, it stops moving, thereby precisely controlling the position of the plastic guide rail and enabling precise processing. This solves the problem that the positional accuracy of the plastic guide rail in the length direction cannot be guaranteed during feeding.

[0018] 2. This invention achieves the function of controlling the lifting and lowering of the limit block through a mounting base, connecting rod, gas spring, and control mechanism, thereby releasing the limit block from restricting the movement of the plastic guide rail. During operation, material is fed through the feeding guide rail and unloaded at the end of the support guide rail away from the feeding guide rail, thus achieving continuous processing, avoiding conflicts during loading and unloading, and further improving processing efficiency.

[0019] 3. This invention achieves the function of automatically raising and lowering the limiting block through an end seat, a first elastic element, a first bracket, and a guide plate. When the plastic guide rail moves to the contact station, it contacts the limiting block and pushes the limiting block to the limiting station, and the end seat is no longer squeezed by the guide plate. During this process, the end seat gradually moves away from the connecting rod under the elastic force of the first elastic element, and the first elastic element extends. The gas spring changes from a contracted state to an extended state under the elastic force of the first elastic element, causing the limiting block to have an upward tendency. At this time, the upward movement of the limiting block is restricted by the limiting component. After the die-cutting process is completed, the control component releases the movement restriction of the limiting component on the limiting block, and the limiting block moves upward under the elastic force of the gas spring to facilitate subsequent material unloading.

Detailed Implementation

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1-4 and Figure 10A fully automatic die-cutting device for the insertion of a plastic guide rail of a film cutter includes a frame 1, an upper die base 11 and a lower die base 12 on the frame 1, a die-cutting blade 111 on the upper die base 11, a feeding guide rail 13 on the frame 1, a first linear driver 131 for pushing the plastic guide rail 4 to move on the feeding guide rail 13, and a support guide rail 14 on the lower die base 12 for guiding the movement of the plastic guide rail 4, and a limiting block 141 on the support guide rail 14 for restricting the movement of the plastic guide rail 4.

[0033] This invention achieves precise control of the position of the plastic guide rail 4 through the feeding guide rail 13, the first linear actuator 131, the support guide rail 14, and the limiting block 141. During the feeding process, if the position of the plastic guide rail 4 is controlled solely by controlling the pushing stroke of the first linear actuator 131, inaccurate positioning will occur if the movement of the plastic guide rail 4 is obstructed or continues to move due to inertia, thus affecting the die-cutting accuracy. Therefore, while guiding the movement of the plastic guide rail 4 through the support guide rail 14, the limiting block 141 restricts the movement stroke of the plastic guide rail 4. The first linear actuator 131 pushes the plastic guide rail 4 for feeding, and the movement stops when the plastic guide rail 4 abuts against the limiting block 141, thereby precisely controlling the position of the plastic guide rail 4 for accurate processing. When the equipment is working, the plastic guide rail 4 to be processed is first placed on the feeding guide rail 13. The first linear actuator 131 on the feeding guide rail 13 automatically pushes the plastic guide rail 4 forward, realizing automatic feeding. This design avoids the tedious operation of manual feeding and improves work efficiency. After the plastic guide rail 4 is pushed onto the support guide rail 14 of the lower mold base 12, the limiting block 141 on the support guide rail 14 restricts the position of the plastic guide rail 4, ensuring that it stays in the accurate processing position. This positioning method is simple and reliable, and can guarantee the accuracy of each processing. After the plastic guide rail 4 is positioned, the upper mold base 11 drives the die-cutting blade 111 to move downward to cut the plastic guide rail 4. After cutting, the upper mold base 11 returns to its original position, waiting for the next processing. The whole process is completed automatically without manual intervention.

[0034] Reference Figure 5 and Figure 6 The lower mold base 12 is provided with a mounting base 2, and the mounting base 2 is provided with a connecting rod 21; the connecting rod 21 is provided with a gas spring 22, and the piston rod of the gas spring 22 is connected to the limit block 141; the mounting base 2 is provided with a control mechanism 3 for controlling the limit block 141 to rise and fall in the vertical direction.

[0035] This invention utilizes a mounting base 2, a connecting rod 21, a gas spring 22, and a control mechanism 3 to control the lifting and lowering of the limiting block 141, thereby releasing the restriction on the movement of the plastic guide rail 4 imposed by the limiting block 141. During operation, material is fed via the feeding guide rail 13, and unloaded from the end of the supporting guide rail 14 away from the feeding guide rail 13, achieving continuous processing, avoiding conflicts during loading and unloading, and further improving processing efficiency. During processing, the operator automatically feeds the material via the feeding guide rail 13 and the first linear actuator 131, and the limiting block 141 on the supporting guide rail 14 restricts the movement of the plastic guide rail 4 to ensure feeding accuracy. Die-cutting is then performed. After processing, the control mechanism 3 controls the limiting block 141 to move upwards, releasing the restriction on the movement of the plastic guide rail 4 imposed by the limiting block 141. At this point, the operator again uses the first linear actuator 131 to push the plastic guide rail 4 to be processed along the feeding guide rail 13 into the support guide rail 14. The new plastic guide rail 4 will push the processed plastic guide rail 4 to continue moving, thereby moving the processed plastic guide rail 4 out of the support guide rail 14. After the processed plastic guide rail 4 has moved a specified distance, the first linear actuator 131 is stopped. Then, the operator uses an automated material handling hand to completely move the plastic guide rail 4 out of the support guide rail 14. The material handling hand is not shown in the figure. After the unloading action is completed, the control mechanism 3 controls the limit block 141 to move down again. The limit block 141 restricts the movement of the plastic guide rail 4 to ensure the feeding accuracy of the next plastic guide rail 4.

[0036] Reference Figure 6 and Figure 7 The control mechanism 3 includes a limiting component 31 and a control component 32; the limiting component 31 is used to limit the movement of the limit block 141 in the vertical direction; the control component 32 is used to release the limiting component 31 from restricting the upward movement of the limit block 141; when the control component 32 releases the limiting component 31 from restricting the upward movement of the limit block 141, the limit block 141 moves upward under the elastic force of the gas spring 22.

[0037] This invention achieves the function of automatically moving the limiting block 141 upwards through the cooperation of the limiting component 31 and the control component 32. During the die-cutting process, the limiting component 31 maintains a constraint on the limiting block 141, preventing it from moving upwards. This restricts the movement of the plastic guide rail 4, ensuring it remains in the accurate processing position. When the height of the limiting block 141 needs adjustment, the control component 32 releases the constraint from the limiting component 31. At this time, the limiting block 141 automatically moves upwards under the elastic force of the gas spring 22, releasing the movement restriction on the plastic guide rail 4, facilitating material unloading by the operator and adapting to different processing needs.

[0038] Reference Figure 5 and Figure 6The gas spring 22 has an end seat 221 at the end away from the connecting rod 21, and the end seat 221 has a first elastic element 222 connected to the connecting rod 21; the mounting base 2 has a first bracket 23, and the first bracket 23 has a guide plate 231 for guiding the end seat 221 to rise and fall; the support guide rail 14 has a contact position and a limiting position, and the limiting block 141 can move between the contact position and the limiting position; when the limiting block 141 is in the contact position, the end seat 221 is squeezed by the guide plate 231, the gas spring 22 is in a compressed state, and the limiting block 141 has a downward tendency; when the limiting block 141 is in the limiting position, the gas spring 22 is in an extended state, and the limiting block 141 has an upward tendency.

[0039] This invention achieves the function of automatically raising and lowering the limiting block 141 through the end seat 221, the first elastic element 222, the first bracket 23, and the guide plate 231. In the working state, the first linear actuator 131 drives the plastic guide rail 4 from the feeding guide rail 13 to the support guide rail 14. When the plastic guide rail 4 moves to the contact position, it contacts the limiting block 141 and pushes the limiting block 141 to the limiting position, and the end seat 221 is no longer subjected to the squeezing action of the guide plate 231. During this process, the end seat 221 gradually moves away from the connecting rod 21 under the elastic force of the first elastic element 222, and the first elastic element 222 extends. The gas spring 22 changes from a contracted state to an extended state under the elastic force of the first elastic element 222, causing the limiting block 141 to have an upward tendency. At this time, the limiting component 31 restricts the upward movement of the limiting block 141. After the die-cutting process is completed, the control component 32 releases the movement restriction of the limiting component 31 on the limiting block 141. The limiting block 141 moves upward under the elastic force of the gas spring 22 to facilitate the subsequent unloading operation. Then, the first linear driver 131 pushes the new plastic guide rail 4, and during the loading process, the new plastic guide rail 4 pushes the finished plastic guide rail 4 out of the lower mold base 12. After pushing a certain distance, the operator removes the finished plastic guide rail 4, completing the unloading action.

[0040] Reference Figure 6 and Figure 7 The mounting base 2 has a sliding groove 24; the mounting base 2 has a slider 241 that slides in cooperation with the sliding groove 24, and the connecting rod 21 is hinged to the slider 241; the slider 241 has a second elastic element 242 that is connected to the mounting base 2.

[0041] This invention achieves the function of controlling the movement of the limiting block 141 from the limiting station to the releasing station through the slide groove 24, the slider 241, and the second elastic element 242. After the material unloading action is completed, the limiting block 141 is automatically reset. After the die-cutting process is completed, the control component 32 releases the upward movement restriction of the limiting component 31 on the limiting block 141. The limiting block 141 moves upward under the elastic force of the gas spring 22, releasing the movement restriction on the plastic guide rail 4. Then, the first linear driver 131 controls the new plastic guide rail 4 to enter the support guide rail 14, and pushes the processed plastic guide rail 4 through the new plastic guide rail 4. At this time, the limiting block 141 abuts against the top of the plastic guide rail 4. Since the limiting block 141 is no longer squeezed by the plastic guide rail 4, the slider 241 moves towards the plastic guide rail 4 under the elastic force of the second elastic element 242, and then pushes the limiting block 141 from the limiting station to the contact station through the connecting rod 21. During this process, the end seat 221 of the gas spring 22 is squeezed by the guide plate 231, the first elastic element 222 is compressed and contracts, and the end seat 221 continues to move towards the connecting rod 21. The gas spring 22 changes from an extended state to a contracted state. At this time, the limiting block 141 is subjected to the elastic force of the gas spring 22 and has a downward tendency. After the processed plastic guide rail 4 has moved a specified distance, the drive of the first linear actuator 131 is stopped, and the operator removes the plastic guide rail 4. After the plastic guide rail 4 separates from the limiting block 141, the limiting block 141 moves downward under the elastic force of the gas spring 22. Then the operator drives the plastic guide rail 4 to move again through the first linear actuator 131. The plastic guide rail 4 contacts the limiting block 141 at the contact station, and then pushes the limiting block 141 to the limiting station to complete the loading action. The drive stroke of the first linear actuator 131 is divided into two segments, which can stably control the reset of the limit block 141. To improve the automation of the equipment, an infrared sensor is set at the end of the support rail 14 away from the feeding rail 13. The infrared sensor is not shown in the figure. The infrared sensor automatically senses the feeding status of the plastic guide rail 4. After the feeding action is completed, the first linear actuator 131 is automatically started to complete the feeding work.

[0042] Reference Figure 7 and Figure 8 The limiting component 31 includes a limiting strip 311 and a third elastic member 312; the mounting base 2 has a receiving groove for accommodating the limiting strip 311; the limiting strip 311 is slidably installed in the receiving groove; the two ends of the third elastic member 312 are respectively connected to the limiting strip 311 and the groove wall of the receiving groove.

[0043] This invention achieves the function of restricting the upward movement of the limiting block 141 through the limiting strip 311 and the third elastic member 312. When the limiting strip 311 is in the extended state, the limiting block 141 abuts against the limiting strip 311, and the limiting strip 311 can only move horizontally with the extension and retraction of the third elastic member 312. Therefore, when the limiting strip 311 abuts against the limiting block 141, it can restrict the limiting block 141 from moving vertically. After the die-cutting process is completed, the limiting strip 311 is controlled by the control component 32 to move towards the receiving groove, the third elastic member 312 retracts, and the limiting strip 311 is completely retracted into the receiving groove. At this time, the limiting strip 311 separates from the limiting block 141, and the limiting block 141 moves upward under the elastic force of the gas spring 22. When the limiting block 141 moves to the contact station again and separates from the plastic guide rail 4, the limiting block 141 moves down under the elastic force of the gas spring 22, and the limiting strip 311 extends out of the receiving groove under the elastic force of the third elastic element 312, which restricts the limiting block 141 from moving up again.

[0044] Reference Figure 7 and Figure 8 The control component 32 includes a push plate 321, a guide rod 322, and a fourth elastic element 323. The push plate 321 is connected to the guide rod 322, and the guide rod 322 is slidably mounted on the mounting base 2 in the vertical direction. The two ends of the fourth elastic element 323 are connected to the push plate 321 and the mounting base 2, respectively. The push plate 321 can move up and down in the vertical direction as the fourth elastic element 323 extends and retracts. When the upper mold base 11 moves down for die cutting, it pushes the push plate 321 down. The limiting strip 311 has an arc surface on the side near the push plate 321. When the push plate 321 moves down, it squeezes the arc surface of the limiting strip 311 and pushes the limiting strip 311 into the receiving groove.

[0045] This invention achieves the function of controlling the retraction of the limiting strip 311 into the receiving groove through the push plate 321, guide rod 322, and fourth elastic element 323, thereby releasing the upward movement restriction of the limiting block 141 by the limiting component 31. The mounting base 2 is provided with a second bracket 26 that can move vertically, and the second bracket 26 is connected to the push plate 321. During die-cutting, the upper die base 11 is driven downward by a hydraulic rod (not shown in the figure). While the upper die base 11 moves downward for die-cutting, it presses down the second bracket 26, which in turn drives the push plate 321 downward. The fourth elastic element 323 retracts under pressure. As the push plate 321 moves downward, it presses against the arc surface of the limiting strip 311 and pushes the limiting strip 311 into the receiving groove. After the limiting strip 311 separates from the limiting block 141, the upward movement restriction on the limiting block 141 is released.

[0046] Reference Figure 2 and Figure 9The upper mold base 11 is provided with a main rod 112 and a secondary rod 113. The main rod 112 is connected to the upper mold base 11, and the secondary rod 113 is slidably engaged with the main rod 112. The main rod 112 is provided with a fifth elastic element 114 connected to the secondary rod 113.

[0047] This invention achieves the function of pushing the second support 26 through the main rod 112, the secondary rod 113, and the fifth elastic element 114. The main rod 112 is equipped with a hydraulic damper, which is not shown in the figure. After the upper mold base 11 is controlled to move downwards, while pushing the second support 26, the extension and retraction of the fifth elastic element 114 and the secondary rod 113 achieve a buffering effect, thereby preventing excessive vibration from affecting the state of the limiting block 141 and other parts when pushing the second support 26.

[0048] Reference Figures 3-5 The mounting base 2 is equipped with a contact sensor 25 for detecting the position of the limit block 141.

[0049] This invention uses a contact sensor 25 to detect the position of the limiting block 141. During the feeding process, the first linear actuator 131 pushes the plastic guide rail 4 to move. When the plastic guide rail 4 pushes the limiting block 141 from the contact station to the restriction station, the limiting block 141 contacts the contact sensor 25, and then the driving of the first linear actuator 131 stops, thus avoiding the first linear actuator 131 from excessively pushing the plastic guide rail 4 and causing the plastic guide rail 4 to deform.

[0050] Reference Figure 5 and Figure 6 The mounting base 2 has a mounting groove 27 for accommodating the connecting rod 21, and elastic protrusions 271 are provided on both sides of the mounting groove 27.

[0051] This invention uses the mounting groove 27 and the elastic protrusion 271 to make the connecting rod 21 tend to move towards the contact position when it is in the restricted position. After the limiting block 141 moves upward, it can then move towards the contact position under the elastic force of the second elastic member 242. When the limiting block 141 is in the restricted position, the extension direction of the connecting rod 21 and the extension direction of the slide groove 24 are in the same straight line. Although the second elastic member 242 can apply pressure to the limiting block 141 through the connecting rod 21, if the balance of the limiting block 141 cannot be broken, the movement of the limiting block 141 may be hindered. For this reason, the elastic protrusion 271 is provided. When the limiting block 141 is in the restricted position under the push of the plastic guide rail 4, it will squeeze the elastic protrusion 271. After the limiting block 141 moves upward, the elastic force provided by the elastic protrusion 271 can break the force balance of the limiting block 141, so that it can move smoothly under the elastic force of the second elastic member 242.

[0052] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
