Description

Technical Field

[0001] This invention relates to the field of leather cutting tools, and in particular to a leather cutting device for bag manufacturing. Background Technology

[0002] In the manufacturing process of bags and luggage, precise cutting of the selected leather is necessary to ensure a seamless fit between all components. However, leather is soft and prone to slippage, requiring effective positioning before cutting to ensure cut stability. Furthermore, leather debris easily adheres to the blade after cutting, and failure to clean it promptly will directly affect subsequent cutting accuracy. While existing technology provides preliminary positioning before cutting, cleaning the blade after cutting still relies on manual labor. This not only increases the workload for operators but also results in low cleaning efficiency, difficulty in ensuring consistent cleaning, and an inability to meet the demands of continuous production. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that the cleaning of the blade after cutting still depends on manual labor.

[0004] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a leather cutting device for bag manufacturing, which includes,

[0005] A cutting mechanism includes a cutter, a positioning component disposed at the top of the cutter, and a hinge seat for mounting the cutter and the positioning component;

[0006] A frame, wherein the hinged seat is mounted on the top of the frame;

[0007] The positioning component includes a mounting plate, an elastic element disposed at the bottom end of the mounting plate, and an inflatable element disposed at the top end of the mounting plate;

[0008] Specifically, after the leather is placed on the frame surface, the cutter is held and pressed to rotate around the hinge seat. Before the cutter contacts the leather to cut, the elastic element presses and positions the leather, using elastic pre-compression to prevent misalignment during cutting and ensure cut accuracy. After cutting, during the cutter reset process, compressed gas stored in the inflation element is ejected through the air passage structure inside the cutter to automatically blow away leather debris adhering to the blade surface, preventing debris residue from affecting subsequent cutting quality and achieving simultaneous automation of cutting and cleaning.

[0009] In a preferred embodiment of the leather cutting device for bag manufacturing according to the present invention: the cutting knife includes a blade, a handle fixedly connected to one end of the blade, and a connector fixedly connected to the other end of the blade;

[0010] Specifically, by holding the handle and pressing it, the joint rotates about the hinge seat and causes the blade to cut and trim the leather.

[0011] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: the hinge seat includes a mounting frame mounted and connected to the frame, a rotating shaft rotatably connected to the mounting frame, and a clip fixedly connected to the outside of the rotating shaft; the rotating shaft is connected to the mounting frame via a torsion spring;

[0012] The connector is fitted inside the clip head, and the mounting plate is installed on the top of the clip head;

[0013] Specifically, by gripping the handle and applying downward pressure, the connector rotates around the pivot of the hinge seat, thereby driving the blade to cut the leather. During this process, the torsion spring connecting the pivot and the mounting bracket undergoes elastic deformation and stores restoring force. When the handle is released, the torsion spring releases the restoring force, driving the pivot to rotate in the opposite direction, causing the cutter to automatically return to its initial position, facilitating continuous reuse and improving operational efficiency.

[0014] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: the elastic element includes a slide rod slidably connected to the mounting plate, a rubber pad fixedly connected to the bottom end of the slide rod, a piston fixedly connected to the top end of the slide rod, and a spring sleeved on the outside of the slide rod;

[0015] The spring is connected to the mounting plate, and its other end is connected to the rubber pad;

[0016] Specifically, before the cutter rotates downward to cut, the rubber pad first contacts the leather surface; as the downward pressure continues, the rubber pad is driven by the reaction force of the leather to slide the slide rod into the housing, while compressing the spring; at this time, the elastic pressure generated by the spring continues to act on the leather through the rubber pad, forming a stable clamping and positioning force, ensuring that the leather will not slip due to force when the blade cuts, fundamentally avoiding quality problems such as incorrect cutting or crooked cuts.

[0017] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: the elastic element further includes a support rod fixedly connected to the outside of the slide rod, a connecting tube fixedly connected to the outside of the support rod, and an air hole opened at the bottom of the outside of the connecting tube.

[0018] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: the inflatable component includes a housing fixedly connected to the top of the mounting plate, an airbag disposed inside the housing, and an air cavity formed inside the housing;

[0019] The air cavity is connected to the airbag, and the airbag is connected to the connecting tube;

[0020] Specifically, as the slide rod slides into the housing, it drives the piston to slide synchronously within the air chamber, compressing the gas in the air chamber and injecting it into the airbag for storage. During this process, the connecting pipe, which is fixedly connected to the slide rod via the support rod, moves upward, causing the air hole to disengage from the main air channel, thus blocking the airbag from the external air channel. This design ensures that during the cutting process, gas can only enter the airbag in one direction for energy storage and will not leak out prematurely, thus reserving sufficient air pressure energy for automatic cleaning after cutting.

[0021] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: a one-way valve is provided in the communication channel between the air chamber and the air bag, so that the gas in the air chamber enters the air bag in only one direction; the air chamber is connected to the outside of the housing through the one-way valve, so that the gas outside the housing enters the air chamber in only one direction.

[0022] Specifically, by utilizing the one-way valve located in the communication channel between the air chamber and the airbag, and another one-way valve located in the connection channel between the air chamber and the outside of the housing, one-way flow control of the gas is achieved. When the piston is pressed down, gas can only enter the airbag from the air chamber in one direction. When the piston is reset by the action of the spring, external air can only enter the air chamber in one direction to replenish it, ensuring that the airbag can be effectively inflated with each press and guaranteeing a continuous supply of clean air.

[0023] In a preferred embodiment of the leather cutting equipment for bag manufacturing described in this invention: a main air passage is provided inside the blade, and a side air passage is provided on the outer wall of the blade, and the main air passage is connected to the side air passage.

[0024] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: the connecting pipe is slidably connected to the tip of the blade, and the connecting pipe is connected to the main air passage through the air hole;

[0025] Specifically, after the cutting is completed and the handle is released, the cutter returns to its original position under the action of the torsion spring. At this time, the slide rod slides outward under the action of the spring, causing the connecting tube to move downward, so that the air hole reconnects with the main air channel. The compressed gas stored in the airbag is ejected sequentially through the main air channel and the side air channel to clean the surface of the blade. In particular, since the elastic element on the side closer to the handle releases the pressure on the leather and returns to its original position first when the cutter returns to its original position, the inflation element on this side connects with the main air channel first and ejects gas, giving priority to cleaning the higher part of the blade. Subsequently, the other side is cleaned in turn. This sequential cleaning method from high to low ensures that the debris falls naturally under the action of gravity and does not re-adhere to the cleaned lower area, significantly improving the cleaning effect and avoiding secondary pollution caused by debris falling and adhering to the upper part during simultaneous cleaning.

[0026] In a preferred embodiment of the leather cutting equipment for bag manufacturing according to the present invention: the frame includes a workbench, a cutting plate fixedly connected to the top of the workbench, and a drawer disposed inside the workbench; the mounting bracket is installed on the top of the workbench;

[0027] Specifically, once the leather is placed on the cutting board and adjusted to the appropriate position, the cutting operation can be completed by pressing the cutter; the drawer can be used to store cutting tools or accessories, optimizing the tidiness of the workspace and the convenience of operation.

[0028] The beneficial effects of this invention are as follows: Firstly, the rubber pad presses against the leather, causing the slide rod to compress the spring, achieving elastic pre-compression positioning before cutting and preventing the leather from slipping or misaligning. Secondly, the piston's sliding compression within the air chamber, combined with the one-way valve's unidirectional conduction, stores gas in the air bladder, achieving automatic energy storage during the cutting process. After cutting, the spring resets, causing the connecting tube to move downwards, connecting the air hole to the main air channel, allowing the gas in the air bladder to be ejected through the side air channel to automatically clean the blade, preventing debris residue. Furthermore, the rubber pad near the handle resets first, achieving sequential cleaning of the blade with priority cleaning at higher points and subsequent cleaning at lower points, preventing secondary contamination. Simultaneously, the elastic restoring force of the torsion spring between the rotating shaft and the mounting bracket enables automatic blade reset, facilitating continuous operation.

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0039] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new techniques. Furthermore, specific terms may be chosen independently, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of the invention.

[0040] Reference Figures 1-8 This embodiment provides a leather cutting device for bag manufacturing, which includes,

[0041] The cutting mechanism 1 includes a cutter 11, a positioning component 12 disposed at the top of the cutter 11, and a hinge seat 13 for mounting the cutter 11 and the positioning component 12.

[0042] The frame 2 has a hinged base 13 mounted on its top.

[0043] The positioning component 12 includes a mounting plate 121, an elastic member 122 disposed at the bottom end of the mounting plate 121, and an inflatable member 123 disposed at the top end of the mounting plate 121.

[0044] Specifically, after placing the leather on the surface of the frame 2, the cutter 11 is held and pressed to cause it to rotate around the hinge seat 13. Before the cutter 11 contacts the leather to cut, the elastic element 122 presses and positions the leather, using elastic pre-compression to prevent the leather from shifting during the cutting process and ensure the accuracy of the cut. After the cutting is completed, during the resetting process of the cutter 11, the compressed gas stored in the inflation element 123 is ejected through the air passage structure inside the cutter 11 to automatically blow away the leather debris attached to the surface of the blade 111, avoiding debris residue from affecting the subsequent cutting quality and achieving synchronous automation of cutting and cleaning.

[0045] As one embodiment provided in this application, such as Figures 1-5 The cutter 11 includes a blade 111, a handle 112 fixedly connected to one end of the blade 111, and a connector 113 fixedly connected to the other end of the blade 111.

[0046] Specifically, by holding the handle 112 and pressing it, the joint 113 will rotate about the hinge seat 13 as an axis, and the blade 111 will cut and trim the leather.

[0047] The hinge base 13 includes a mounting bracket 131 that is mounted and connected to the frame 2, a rotating shaft 132 that is rotatably connected to the mounting bracket 131, and a clip 133 that is fixedly connected to the outside of the rotating shaft 132; the rotating shaft 132 is connected to the mounting bracket 131 by a torsion spring.

[0048] The connector 113 is snapped inside the clip head 133, and the mounting plate 121 is installed on the top of the clip head 133;

[0049] Specifically, by gripping the handle 112 and applying downward pressure, the connector 113 rotates around the pivot 132 of the hinge seat 13, thereby driving the blade 111 to cut the leather. During this process, the torsion spring connecting the pivot 132 and the mounting bracket 131 undergoes elastic deformation and stores restoring force. When the handle 112 is released, the torsion spring releases the restoring force, driving the pivot 132 to rotate in the opposite direction, causing the cutter 11 to automatically return to its initial position, which facilitates continuous reuse and improves operating efficiency.

[0050] As one embodiment provided in this application, such as Figures 6-8 The elastic element 122 includes a slide rod 1221 that is slidably connected to the mounting plate 121, a rubber pad 1222 that is fixedly connected to the bottom end of the slide rod 1221, a piston 1223 that is fixedly connected to the top end of the slide rod 1221, and a spring 1224 that is sleeved on the outside of the slide rod 1221.

[0051] Spring 1224 is connected to mounting plate 121, and its other end is connected to rubber pad 1222;

[0052] Specifically, before the cutter 11 rotates downward to cut, the rubber pad 1222 first contacts the leather surface; as the downward pressing action continues, the rubber pad 1222 is driven by the reaction force of the leather to slide the slide bar 1221 into the housing 1231, while compressing the spring 1224; at this time, the elastic pressure generated by the spring 1224 continues to act on the leather through the rubber pad 1222, forming a stable clamping and positioning force, ensuring that the leather will not slip due to force when the blade 111 is cutting, fundamentally avoiding quality problems such as incorrect cutting or crooked cuts.

[0053] As one embodiment provided in this application, such as Figures 6-8 The elastic element 122 also includes a support rod 1235 fixedly connected to the outside of the slide rod 1221, a connecting pipe 1236 fixedly connected to the outside of the support rod 1235, and an air hole 1237 opened at the bottom of the outside of the connecting pipe 1236.

[0054] The inflatable component 123 includes a housing 1231 fixedly connected to the top of the mounting plate 121, an airbag 1232 disposed inside the housing 1231, and an air cavity 1233 opened inside the housing 1231.

[0055] The air chamber 1233 is connected to the air bag 1232, and the air bag 1232 is connected to the connecting tube 1236;

[0056] Specifically, as the slide rod 1221 slides into the housing 1231, it drives the piston 1223 to slide synchronously within the air chamber 1233, compressing the gas in the air chamber 1233 and injecting it into the airbag 1232 for storage. During this process, the connecting pipe 1236, which is fixedly connected to the slide rod 1221 via the support rod 1235, moves upward, causing the air hole 1237 to disengage from the main air passage 1111, thus blocking the airbag 1232 from the external air passage. This design ensures that during the cutting process, the gas can only enter the airbag 1232 in one direction for energy storage and will not leak out prematurely, thus reserving sufficient air pressure energy for automatic cleaning after cutting.

[0057] As one embodiment provided in this application, such as Figures 6-8 The communication channel between the air chamber 1233 and the air bag 1232 is provided with a one-way valve 1234, so that the gas in the air chamber 1233 can only enter the air bag 1232 in one direction; the air chamber 1233 is connected to the outside of the shell 1231 through the one-way valve 1234, so that the gas outside the shell 1231 can only enter the air chamber 1233 in one direction.

[0058] Specifically, by using a one-way valve 1234 located in the communication channel between the air chamber 1233 and the air bag 1232, and another one-way valve 1234 located in the external connection channel between the air chamber 1233 and the housing 1231, one-way flow control of gas is achieved. When the piston 1223 is pressed down, gas can only enter the air bag 1232 from the air chamber 1233 in one direction. When the piston 1223 is reset under the action of the spring 1224, external air can only enter the air chamber 1233 in one direction to replenish it, ensuring that the air bag 1232 can be effectively inflated with each press, and ensuring a continuous supply of clean air.

[0059] As one embodiment provided in this application, such as Figures 6-8 The blade 111 has a main air passage 1111 inside and a side air passage 1112 on the outer wall of the blade 111. The main air passage 1111 and the side air passage 1112 are connected.

[0060] The connecting tube 1236 is slidably connected to the top of the blade 111, and the connecting tube 1236 is connected to the main air passage 1111 through the air hole 1237;

[0061] Specifically, after the cutting is completed and the handle 112 is released, the cutter 11 returns to its original position under the action of the torsion spring; at this time, the slide rod 1221 slides outward and returns to its original position under the action of the spring 1224, causing the connecting tube 1236 to move downward, so that the air hole 1237 reconnects with the main air channel 1111, and the compressed gas stored in the air bag 1232 is ejected sequentially through the main air channel 1111 and the side air channel 1112 to blow clean the surface of the blade 111; in particular, because the cutter 11 is close to the handle 112 when it returns to its original position. The elastic element 122 on one side is the first to release the pressure on the leather and return to its original position. The inflatable element 123 on this side is the first to connect with the main air channel 1111 and spray gas to blow and wash the part of the blade 111 that is at a higher position first. Then the other side is blown and washed in turn. This high-to-low sequential blowing and washing method ensures that the debris falls naturally under the action of gravity and will not re-adhere to the cleaned lower area, which significantly improves the cleaning effect and avoids secondary pollution caused by debris falling and adhering to the upper position due to simultaneous blowing and washing.

[0062] As one embodiment provided in this application, such as Figure 1 The frame 2 includes a workbench 21, a cutting board 22 fixedly connected to the top of the workbench 21, and a drawer 23 disposed inside the workbench 21; the mounting bracket 131 is mounted on the top of the workbench 21.

[0063] Specifically, once the leather is placed on the cutting board 22 and adjusted to the appropriate position, the cutting operation can be completed by pressing the cutter 11; the drawer 23 can be used to store cutting tools or accessories, optimizing the tidiness of the workspace and the convenience of operation.

[0064] In summary, gripping and pressing the handle 112 causes the connector 113 to rotate around the pivot 132 and compress the torsion spring, allowing the blade 111 to cut. Before cutting, the rubber pad 1222 presses against the leather and pushes the slide rod 1221 to compress the spring 1224, forming a pre-tight positioning. At the same time, the piston 1223 slides in the air chamber 1233, injecting gas into the air bag 1232 through the one-way valve 1234. The support rod 1235 moves the connecting tube 1236 upwards, causing the air port 1237 to disengage from the main air passage 1. 111 is used to block pressure relief; after cutting, the torsion spring releases energy and drives the cutter 11 to reset, the spring 1224 pushes the slide rod 1221 to move outward, so that the connecting tube 1236 moves down and the air hole 1237 connects to the main air channel 1111, the gas in the airbag 1232 is sprayed out through the main air channel 1111 and the side air channel 1112 to blow clean the blade 111, and the elastic element 122 near the handle 112 resets first and blows clean the high parts first, so as to achieve cleaning from high to low to avoid secondary pollution.

[0065] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
