DETAILED DESCRIPTION

[0037] The utility model will be described further, combined with the drawings and specific implementation, it is to be explained that, in the premise that there is no conflict, the following described each embodiment or each technical feature between can be combined to form new embodiment.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 And Figure 8 As shown in the drawings, the embodiment provides a leather cutting machine for leather production, the leather cutting machine includes rack 2, pressing member, cutting module, conveying member, the pressing member, cutting module, conveying member and dust removal member are arranged on the rack 2, the conveying member conveys the leather 12 to be cut to the cutting station 7, the pressing member is pressed in the cutting station 7 to the leather 12 to be cut, and the cutting module cuts the leather 12 to be cut pressed in the cutting station 7.

[0039] Among them, the cutting member linearly changes the cutting posture and cuts the leather 12 to be cut.

[0040] Optionally, the cutting module includes deformable blade 20, deformation adjusting member, lifting rod 14, lifting seat 15, lifting drive mechanism and two limiting rods 16, two limiting holes are formed in the lifting seat 15 body, one end of the two limiting rods 16 is connected with the upper end face of the rack 2, the other end of the two limiting rods 16 is perpendicular to the upper end face away from the rack 2 and penetrates the limiting hole, one end of the lifting rod 14 is connected with the lifting seat 15, the other end of the lifting rod 14 is driven by the lifting drive mechanism to form a lifting part in succession, the lifting part is arranged on the rack 2, and the blade 20 and the deformation adjusting member are arranged on the side of the lifting seat 15 towards the cutting station 7.

[0041] Among them, the axis of the lifting rod 14 is parallel to the axis of the two limiting rods 16, that is, the lifting rod 14 and the two limiting rods 16 are parallel to each other.

[0042] Specifically, the lifting part approaches the cutting station 7 during the lifting operation, and cuts the transported or conveyed leather 12 to be cut;

[0043] Meanwhile, the deformation adjusting member is adjusted according to the arc line of the leather 12 required by the user or design, and triggers the deformation adjusting member to adjust the blade 20, so as to linearly adjust the blade 20 to the required arc;

[0044] Optionally, the deformation adjusting member comprises a placing seat 19, an adjusting rod 24, an auxiliary air bag 25, an electric pump, an electronic pressure release valve, and an adjusting driving mechanism, the placing seat 19 is symmetrically arranged on one side of the lifting seat 15 facing the cutting station 7 to form a placing cavity for placing the blade 20, one end of the adjusting rod 24 is drivingly connected with the adjusting driving mechanism to form an adjusting part, the adjusting part extends to one side of the placing cavity, the electric pump is connected with the auxiliary air bag 25 through a gas supply pipeline to form an auxiliary part, the auxiliary part is arranged on the other side of the placing cavity away from the adjusting part, and the electronic pressure release valve is arranged on the auxiliary air bag 25 and communicates with the inside of the auxiliary air bag 25.

[0045] In this embodiment, the deformation adjusting member adjusts the blade 20, so that the blade 20 can be adjusted and cut the leather 12 to be cut;

[0046] As shown in Figure 8 , wherein the deformation adjusting member further comprises a push plate 28, the push plate 28 is made of rubber and arranged on one side of the adjusting rod 24 close to the blade 20 to increase the contact area;

[0047] After adjustment, since the auxiliary air bag 25 is arranged on the opposite sides of the adjusting rod 24 and assists in supporting the blade 20, a stable deformation amount of the blade 20 is provided, and the leather 12 to be cut is cut in cooperation with the lifting part.

[0048] During the cutting process, the lifting rod 14 approaches the cutting station 7 under the driving of the lifting driving rod mechanism, and during the movement, the lifting seat 15 and the blade 20, the deformation adjusting member and the pressing member arranged on the lifting seat 15 move together under the limiting action of the at least two limiting rods 16, so as to cut the leather 12 to be cut in the cutting station 7;

[0049] After one cutting is finished, the lifting part gradually lifts the lifting seat 15 away from the leather 12 to be cut and away from the cutting station 7, and adjusts the deformation amount of the blade 20 by the deformation adjusting member, so as to realize the cutting of the arc of the lifting seat 15.

[0050] Meanwhile, when the inflation amount of the auxiliary air bag 25 needs to be adjusted, the auxiliary air bag 25 is inflated by controlling the electric pump, so that the auxiliary air bag 25 assists in supporting the deformed blade 20 to prevent the blade 20 from being broken due to excessive deformation during the cutting process;

[0051] Through the cooperation of the adjusting part and the auxiliary air bag 25, the two sides of the blade 20 can be assisted to support, and the accuracy and reliability of the blade 20 to the leather 12 to be cut are improved.

[0052] Among them, the auxiliary air bag 25 and the adjusting part limit from both sides of the blade 20, also prevent the blade 20 from offsetting and cutting accuracy from being reduced.

[0053] Meanwhile, the height of the blade 20 is higher than the plane where the auxiliary air bag 25 and the placing seat 19 are located, so that the cutting edge of the blade 20 preferentially contacts the leather 12 to be cut and cuts the leather 12 to be cut. In addition, in this example, the blade 20 is selected according to the thickness of the leather 12 to be cut, and the blade 20 is a deformable blade 20;

[0054] As Figure 8 , a magnetic attraction piece is arranged between the placing seat 19 and the blade 20, which magnetically attracts the blade 20 to prevent the blade 20 from falling off. Meanwhile, a rubber pad 26 is arranged between the placing seat 19 and the blade 20, and the deformation of the rubber pad 26 makes the blade 20 not easy to separate during the offset deformation, thereby improving the stability and reliability of the blade 20.

[0055] In this embodiment, the pressing member is arranged on the lifting seat 15 and moves with the lifting seat.

[0056] Optionally, the pressing member includes a pressing air bag 21, an inflation pump, an electronic air release valve, and at least one pressure sensor 27. The inflation pump is connected to the pressing air bag 21 through an inflation pipeline. The at least one pressure sensor 27 is arranged on the contact end surface of the pressing air bag 21 and the leather 12 to be cut. The electronic air release valve is arranged on the contact end surface of the pressing air bag 21 away from the leather 12 to be cut and communicates with the inside of the pressing air bag 21.

[0057] The pressing member is arranged on the side of the lifting seat 15 facing the cutting station 7 and moves with the lifting seat 15.

[0058] The pressure sensor 27 collects the pressure value of the pressing air bag 21 applied to the surface of the leather 12 in real time and feeds back the data to the central processor. The central processor compares the collected pressure value with the preset target pressure value and controls the opening state of the inflation pump or the electronic air release valve in real time to form a precise closed-loop control and ensure that the pressing force is always in the best range.

[0059] The pressure sensor 27 collects real-time pressure data at the contact surface between the pressing air bag 21 and the leather 12 at a high frequency and transmits the data to the central processor.

[0060] Specifically, when the pressure is lower than the target value, the central processor sends an instruction to start the air pump to supplement air; when the pressure is higher than the target value, the central processor opens the electronic air release valve to release air in an appropriate amount, thereby achieving accurate pressure regulation.

[0061] Multiple pressure sensors 27 are arranged at different positions of the pressing air bag 21 to uniformly collect pressure data at the contact surface between the air bag and the leather 12. The central processor comprehensively analyzes the pressure values at multiple points to ensure the uniformity of the stress during the pressing process and avoid damage or misplacement of the leather 12 due to insufficient or excessive local pressure.

[0062] Through the cooperation of the central processor with the air pump and the electronic air release valve, the pressing process can dynamically adjust the pressure according to the material and thickness of the leather 12, adapt to various characteristics of the leather 12, avoid overpressure or insufficient pressing, and ensure that the entire device has the advantages of wide application range and strong automatic adjustment capability.

[0063] The central processor processes feedback data at a millisecond level and adjusts the working state of the air pump and the air release valve in real time to ensure that the pressing air bag 21 can quickly respond to changes in the thickness or hardness of the leather 12, further improving the stability of the pressing process. The user can input target pressure parameters for different materials or thicknesses of the leather 12 through the operation panel of the device, and the central processor automatically adjusts the pressure output range of the pressing air bag 21 according to the input values to adapt to the cutting needs of various types of leather 12. At the same time, the central processor has built-in overpressure protection logic. If the pressure sensor 27 detects abnormally high pressure, the central processor will immediately stop the air pump and open the electronic air release valve to avoid damage to the surface of the leather 12 or failure of the device components.

[0064] Through the overpressure protection mechanism and the rapid reset function of the pressing member, the device can quickly respond and recover to the normal working state in abnormal state, ensuring the safety and efficiency of the device, and ensuring that the entire device has the advantages of high operation safety and fast production efficiency.

[0065] When the lifting seat 15 approaches the leather 12 to be cut, the pressing air bag 21 presses the leather 12 conveyed by the conveying member, and after pressing, the blade 20 synchronously cuts the leather 12;

[0066] After cutting is completed, the electronic air release valve quickly releases the pressure of the pressing air bag 21 to reset the air bag, reducing the standby time of the device and improving the production efficiency.

[0067] In the embodiment, the to-be-cut leather 12 is pressed by the pressing member, so that the to-be-cut leather 12 will not be offset and misaligned, and the entire device has the advantages of high cutting precision, no offset in the cutting process, and good cutting reliability.

[0068] The cooperation of the pressing air bag 21 and the pressure sensor 27 with the central processor ensures that the pressure value can be monitored and dynamically adjusted in real time during the pressing process, so that the leather 12 is uniformly and stably fixed, the cutting precision and reliability are improved, and the entire device has the advantages of accurate pressing force and strong cutting stability.

[0069] In addition, by arranging the multi-point pressure sensor 27 on the pressing air bag and cooperating with the central processor, the pressure of the pressing air bag 21 is uniformly distributed on the entire contact surface, so that the leather 12 is prevented from being offset or having a pressure mark, and the entire device has the advantages of uniform stress and high cutting quality.

[0070] The cooperation of the pressing member and the cutting module ensures that the leather is firmly fixed during the cutting process, prevents the leather from sliding or shifting during cutting, ensures the accuracy of the cutting path and the smoothness of the cutting edge, and ensures that the entire device has the advantage of high-precision cutting.

[0071] Optionally, the conveying member includes a placement groove 18, a feeding ring 17, a connecting rod, a feeding driving mechanism, a suction nozzle 22, a telescopic rod 23, a suction pump, and a telescopic driving mechanism.

[0073] The conveying member further includes a winding roller 11, which is arranged on one side of the cutting station 7 and cooperates with the feeding part to convey the to-be-cut leather 12 to the cutting station 7.

[0074] In the embodiment, the to-be-cut leather 12 is wound and placed on the winding roller 11, and is delivered and conveyed to the cutting station 7 under the rotation of the feeding ring 17.

[0075] In the process of conveying the cut leather 12, the cut leather 12 is adsorbed by the adsorption part, and under the feeding operation of the feeding part, it is transmitted to the cutting station 7 to realize continuous and automatic transmission.

[0076] At the same time, the adsorption nozzle 22 adopts a porous design to increase the adsorption area, and the elastic material edge adapts to the curvature of the surface of different leathers 12, enhances the adsorption stability, and improves the stability and reliability of the adsorption of the cut leather 12.

[0077] The adsorption pump is designed with high negative pressure and low noise, which can form a reliable negative pressure area between the adsorption nozzle 22 and the surface of the leather 12, and ensure that the leather 12 is firmly attached during high-speed transmission.

[0078] The telescopic drive mechanism is a hydraulic or electric telescopic device, which can adjust the height of the adsorption nozzle 22 according to the thickness and size of the leather 12, and ensure that the adsorption nozzle 22 can be accurately attached to the surface of the leather 12. At the same time, the telescopic rod 23 adopts a multi-section design, and is internally provided with an elastic buffer device, which can avoid causing indentations or damage to the leather 12 during telescopic operation.

[0080] The hinged part has a certain angle of movement, which can automatically adjust the inclination angle of the feeding ring 17 according to the change of the transmission path of the leather 12, so as to optimize the transmission trajectory.

[0081] During the feeding operation, the adsorption part, the feeding part and the telescopic part work coordinately through the control system to ensure the continuity and accurate positioning of the leather 12 transmission.

[0082] The whole transmission component is suitable for leathers 12 of various materials and thicknesses, and by adjusting the adsorption strength of the adsorption pump, the speed of the feeding drive mechanism and the telescopic range of the telescopic rod 23, the efficient transmission of soft and thick leather can be realized.

[0083] Through the cooperation of the cutting module and the conveying component, the cut leather can be quickly and stably conveyed to the next process, reducing manual intervention, improving the overall production efficiency, and ensuring that the whole equipment has the advantages of efficient and automatic operation.

[0084] Through the cooperation of the pressing component and the conveying component, the leather can be stably positioned during conveying without additional position adjustment, avoiding leather deviation or inclination, ensuring smooth and continuous leather conveying, and ensuring that the whole equipment has the advantages of efficient and accurate delivery.

[0085] Optionally, the leather cutting machine comprises a dust removal component, which is arranged in the cutting station 7 and is used to adsorb dust in the cutting station 7.

[0086] Optionally, the dust removal component comprises a transparent protective cover 1, a dust suction channel 4, an adsorption rod 9, a dust suction fan 6 and a filter screen 5. The protective cover 1 is detachably buckled on the periphery of the cutting station 7. The adsorption rod 9 is arranged on the periphery of the cutting station 7. The dust suction channel 4 is arranged on both sides of the conveying direction of the leather 12 to be cut. The air inlet 8 of the dust suction channel 4 is arranged opposite to the conveying direction of the leather 12 to be cut. The dust suction fan 6 is arranged in the dust suction channel 4. The filter screen 5 is arranged between the air inlet 8 of the dust suction channel 4 and the dust suction fan 6.

[0087] The protective cover 1 is made of high-strength transparent material (such as polycarbonate) and is detachably buckled on the periphery of the cutting station 7 to form a closed cutting area. The cutting area is isolated from the external environment by the protective cover 1, which reduces dust overflow and facilitates observation of the cutting process by the operator. The opening direction of the dust suction channel 4 is opposite to the conveying direction of the leather 12, forming an air flow interception, which can effectively capture the dust generated during cutting. The inner wall of the dust suction channel 4 is treated with an anti-static coating to prevent dust from adhering to the surface of the channel and affecting the dust suction efficiency.

[0088] In this embodiment, the filter screen 5 is installed between the air inlet 8 of the dust suction channel 4 and the dust suction fan 6 and is responsible for filtering the inhaled dust particles. At the same time, the filter screen 5 is arranged in a multi-layer structure.

[0089] As shown in the drawings, the first layer of coarse filter screen: captures large dust particles. Figure 2

[0090] The second layer of HEPA filter screen: efficiently intercepts fine particles (below PM2.5).

[0091] The third layer of activated carbon filter layer: adsorbs organic matter or odor and purifies the discharged air.

[0092] Optionally, the dust removal component further comprises a high-voltage electrostatic generator and an electric field adsorption plate 10, which is symmetrically arranged on the periphery of the adsorption rod 9. The high-voltage electrostatic generator is electrically connected to the electric field adsorption plate 10.

[0093] The adsorption rod 9 is connected to the electric field adsorption plate 10 and uses the electrostatic field to enhance the adsorption capacity of fine dust particles. The high-voltage electrostatic generator generates an electrostatic field and is electrically connected to the electric field adsorption plate 10. The electric field adsorption plate 10 is symmetrically arranged on the periphery of the adsorption rod 9 to form a strong electric field area.

[0094] Through the cooperation of the high-voltage electrostatic generator and the electric field adsorption plate 10, fine dust (dust particles with electric charge) that is not sucked away by the dust suction fan 6 is captured.

[0095] ​When the cutting machine is started, the dust suction fan 6 and the high-voltage electrostatic generator are started synchronously, and the cutting area enters a closed negative pressure state. During the cutting process, the protective cover 1 isolates the external airflow, and at the same time, the airflow generated by the dust suction fan 6 captures dust particles through the air inlet 8 of the dust suction channel 4. The adsorption rod 9 electrostatically adsorbs the suspended dust generated by cutting, and the electric field adsorption plate 10 enhances the adsorption effect. The inhaled dust particles are filtered layer by layer through the filter screen 5, and then the purified air is discharged, and the dust is concentrated in the dust box waiting for cleaning.

[0096] The arrangement of the dust suction channel 4 covers the entire cutting station 7, and the design of the air inlet 8 direction opposite to the leather 12 transportation direction ensures that the dust is immediately sucked in as it forms, avoiding diffusion. The filter screen 5 is combined with electrostatic adsorption to achieve multi-level filtration, ensuring that the discharged air is dust-free and odor-free, and improving the cleanliness of the working environment. The dust suction fan 6 and the electrostatic auxiliary adsorption work synchronously, which can efficiently handle the large amount of dust generated during the cutting process and prevent accumulation.

[0097] The cooperation design of the adsorption rod 9 and the dust suction channel 4 significantly reduces the adhesion of dust on the surface of the leather 12, avoiding affecting the subsequent processing links (such as splicing, bonding or dyeing). The improvement of dust cleanliness makes the cutting edge smooth and clean, avoiding the roughness of the edge caused by dust accumulation. The transportation of the leather 12 in a closed negative pressure environment avoids secondary pollution, ensuring the surface quality of the leather 12 from the cutting station 7.
