[0001] The utility model relates to the field of leather cutting equipment, in particular to a leather cutting machine which utilizes air outlet flow rate to dissipate heat. Background Art

[0002] Application number CN201710343591.6 is a cutting machine, which is widely used in the leather cutting industry. It is a new design after updating and iteration. The consistency and accuracy of cutting are crucial to ensuring that the product meets strict standards and specifications.

[0003] However, the heat dissipation system inside this cutting machine is still in the form of exhaust or blowing, and an additional exhaust fan is used to dissipate heat inside the cutting machine. However, due to the on-site application environment, the exhaust fan is easily blocked by cutting waste, resulting in no wind or damage. (Cutting waste includes fur, etc. diffused in the air). Utility Model Content

[0004] In order to solve the above problems, the utility model provides a leather cutting machine which utilizes the air outlet flow rate to dissipate heat. With the help of negative pressure fluid in the cutting machine, the internal air is taken away to achieve a heat dissipation purpose.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A leather cutting machine that utilizes the air flow rate to dissipate heat includes an adsorption part on a main body, a fan constituting the adsorption part and an adsorption platform are connected via a pipeline, and is characterized in that it also includes a vacuum generator, an air outlet of the fan is connected to a compressed air inlet of the vacuum generator, and is discharged to the outside through the vacuum generator, wherein an air exhaust port on the vacuum generator on the fan is connected to the interior of the main body, and the compressed air flow formed by the fan is a positive pressure flow in the vacuum generator, so that a negative pressure is formed in the surrounding area of ​​the air exhaust port, and the air inside the main body is sucked away.

[0007] Furthermore, it also includes an exhaust silencer pipe, which is connected to the compressed air outlet of the vacuum generator.

[0008] Furthermore, the exhaust silencer pipe is vertically directed toward the upper side of the rack.

[0009] Furthermore, the adsorption part includes a conveyor belt, and the conveyor belt is provided with air holes. The adsorption platform is located in the area enclosed by the conveyor belt, and the air holes on the conveyor belt can fix the leather on the conveyor belt.

[0010] Furthermore, a cutting mat is sleeved on the conveyor belt, and the cutting mat is made of a breathable material.

[0011] Furthermore, the head and tail ends of the conveyor belt are detachably connected.

[0012] Furthermore, the detachable connection includes a pin shaft, and the two ends of the transmission belt are respectively an extension part and a notch part that cooperate with each other, and the extension part is located in the notch part and is fixed by the pin shaft.

[0013] Beneficial effects of the utility model:

[0014] The original fan's exhaust method is utilized, and the compressed air flow formed in the process of being discharged flows in a positive pressure manner in the vacuum generator, so that negative pressure is formed at the exhaust port, and the air inside the main body is sucked away. The heat dissipated to the surroundings by the fan is also sucked away as the air inside the main body is sucked away. This heat dissipation method only uses a vacuum generator. For the heat dissipation system, the superior volume advantage occupies a very small part of the space inside the main body, and it belongs to the heat dissipation effect achieved by the adsorption part. In short, in addition to the basic adsorption and positioning effect, the entire adsorption platform can also dissipate additional heat inside the main body. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the specification, references to "one embodiment", "an embodiment" or "some embodiments" mean that a particular feature, structure or element described with reference to the embodiment is included in at least one embodiment of the subject matter being described. Thus, sentences in the specification saying "in one embodiment" or "in an embodiment" or "in some embodiments" do not necessarily refer to the same embodiment or embodiments. The particular features, structures or elements may be further combined in any embodiment in a suitable manner.

[0032] like Figure 1-16 As shown, in this embodiment, a leather cutting machine that uses air flow rate to dissipate heat includes a frame 1 and an adsorption part arranged on the frame 1, the adsorption part includes an adsorption platform 2a, a cutting pad 2b, a conveyor belt 2c, and a fan 2d. The surface of the adsorption platform 2a is provided with a plurality of negative pressure holes, and the negative pressure holes are connected to the fan 2d through a pipeline. The fan 2d draws air to form a negative pressure airflow on the negative pressure holes. The conveyor belt 2c and the cutting pad 2b are both closed loops. Figure 5 It can be seen that Z is the conveying direction of the conveyor belt 2c, and along the X direction, the cutting mat 2b is sequentially divided into a placement area 2a-1, a cutting area 2a-2, and a receiving area 2a-3.

[0033] The adsorption platform 2a is located in the area enclosed by the conveyor belt 2c. The negative pressure port is in contact with the inner upper top surface of the conveyor belt 2c in the cutting area. The conveyor belt 2c is provided with air holes 2c′. The cutting mat 2b is made of breathable material (a cutting mat pressed from fibers) and is sleeved on the surface of the conveyor belt 2c. The leather 2e on the cutting mat 2b moves when the cutting mat 2b is driven by the conveyor belt 2c.

[0034] The function of the adsorption platform 2a is mainly to keep the leather 2e in a flat state. The initial state of the leather 2e is in the form of a coil. When feeding, the negative pressure airflow on the negative pressure hole can ensure that the leather 2e is completely attached to the cutting pad 2b, preventing the leather 2e from being affected by the cutting quality due to arching. In addition, before the leather 2e enters the adsorption platform 2a, its moving path is guided by multiple guide rollers (not shown in the figure), among which there is a large drop distance between the guide rollers. Therefore, the leather 2e will pull the leather 2e in the cutting machine out due to its own weight. The negative pressure holes on the adsorption platform 2a can prevent the leather 2e from being pulled back.

[0035] The conveyor belt 2c and the cutting mat 2b are both stretched by the tensioning roller 2f on the frame 1. The conveyor belt 2c and the cutting mat 2b are respectively mounted on the tensioning roller 2f. Rolling seats 2g are provided at both ends of the tensioning roller 2f. The tensioning adjustment block 2h is fixed on the frame 1. The screw 2i passes through the tensioning adjustment block 2h and is connected to the rolling seat 2g. By rotating the screw 2i, the screw 2i is made to perform linear motion in the tensioning adjustment block 2h, so that the tensioning roller 2f moves left and right.

[0036] In some embodiments, the conveyor belt 2c is connected at both ends by a pin shaft (not shown in the figure), and the length of the conveyor belt 2c is customized. Conventional conveyor belts 2c cannot be used in the above-mentioned conveyor belts 2c and cutting mats 2b.

[0037] In particular, the two ends of the conveyor belt 2c can be shapes that fit together, such as an extension portion 2c-1 and a connecting portion 2c-2 with a notch, and the extension portion 2c-1 is located in the notch and the connecting portion 2c-2 and fixed by a pin shaft.

[0038] Since the fan 2d works for a long time and at a high frequency, the heat generated will accumulate in the frame 1. A vacuum generator 100 is provided in the frame 1. The air outlet 100a of the vacuum generator 100 is directly connected to the inside of the frame 1. The air outlet of the fan 2d is connected to the compressed air inlet of the vacuum generator 100 through a hose 4. The compressed air outlet on the vacuum generator 100 is delivered through an exhaust silencer 5.

[0039] In this embodiment, the exhaust method of the original fan 2d is used. The compressed air flow formed during the discharge flows in the vacuum generator 100 in a positive pressure manner, so that a negative pressure is formed at the exhaust port 100a, and the air in the rack 1 is sucked away. The heat dissipated to the surroundings by the fan 2d is also sucked away as the air inside the rack 1 is sucked away. This heat dissipation method only uses the vacuum generator 100. For the heat dissipation system, the superior volume advantage occupies a very small part of the space inside the rack 1, and it is the heat dissipation effect achieved by the adsorption part. In short, in addition to the basic adsorption and positioning effect, the entire adsorption platform 2a can also dissipate heat inside the rack 1.

[0040] from Figure 1-2 It can be seen that the X direction is the discharging direction, and the Y direction is the feeding direction of the coiled material. During the operation, there are situations where the operators stand in the X direction and the Y direction. Therefore, the exhaust silencer pipe 5 is vertically upward, toward the top of the frame 1, and is discharged from the top of the frame 1.

[0041] In some embodiments, the frame 1 is further provided with a receiving table 1a which is located at the same horizontal plane as the adsorption platform 2a. The receiving table 1a extends the entire working surface. In short, it is the same plane as the working surface of the extended cutting pad 2b. The receiving table 1a is located on the inner surface of the cutting pad 2b and is in contact with the upper top surface of the cutting pad 2b. The leather 2e after the cutting operation is completed is transferred through the cutting pad 2b to the position corresponding to the meeting of the receiving table 1a. The receiving table 1a is located outside the working range of the cutting station to improve the safety of the equipment.

[0042] It should be noted that the material receiving platform 1a and the cutting pad 2b are foldable to accommodate overall transportation. When transporting, this embodiment is transported as a whole. The material receiving platform is at the extreme position of the leather cutting machine along the length direction. The foldable implementation method solves the problem of exceeding the container size.

[0043] In addition, the driven roller 2j supporting the cutting pad 2b is also distributed at the extreme position of the leather cutting machine extending in the length direction. When the receiving table 1a is folded, the driven roller 2j is also folded and retracted.

[0044] Specifically, this folding is located at the extreme position of the frame 1 extending in the length direction, and is provided with a folding body, the receiving table 1a and the driven roller 2j are both installed on the folding body, the folding body includes a pair of support plates 6 and a rotating shaft 61, the support plate 6 is provided with an opening structure, the rotating shaft 61 is installed on the frame 1 through the opening structure, wherein the opening structure is connected by two parts, namely, a positioning part 62a having a pair of first planes on the inner circumference and an adjusting part 62b having a first arc surface, the rotating shaft 61 has a geometric shape matching the waist-shaped hole, and also has a positioning part 62a having a pair of first planes on the inner circumference and a first arc surface. The length of the positioning part 62a or the adjusting part 62b, the top surface 61a and the bottom surface 61b of the rotating shaft 61 in the positioning part 62a are in contact with the first plane 62a′, and are constrained by the first plane 62a′, and the support plate 6 is in a positioned state. In the positioned state, the support plate 6 is in an open posture; in the folded state, the rotating shaft 61 is moved into the adjusting part 62b by translation, and after the second arc surface 61c at both ends of the rotating shaft 61 matches the first arc surface 62b′, they rotate counterclockwise under their own gravity to form a folded and stored state.

[0045] It should also be noted that a screw hole 61d is provided on the rotating shaft 61. In the expanded state, the rotating shaft 61 is fixed to the frame 1 by screws.

[0046] The specific usage is as follows:

[0047] In the initial state, the support plate 6 is in an open position. When folding, the screws need to be removed from the shaft 61, and then the folding body is pulled out in the X direction so that the adjustment part 62b and the shaft 61 overlap with each other. Under natural gravity, the folding body is rotated to the extreme position to achieve the folding and storage function.

[0048] In this embodiment, the cutting method is projection cutting, which is achieved by projecting corresponding visual data (patterns, texts, etc.) onto the leather 2e, and then cutting with the cutting head 3.

[0049] A linear moving mechanism is also provided on the frame 1 , and the cutting head 3 is mounted on the linear moving mechanism. The linear moving mechanism provides the cutting head 3 with a function of multi-dimensional spatial movement.

[0050] In the embodiment, the linear motion mechanism includes a double-section suspension beam assembly, which includes a slider seat plate 71 and a first transmission mechanism, a first moving component 73, a second transmission mechanism 74, and a second moving component 75 arranged in sequence from top to bottom. The first transmission mechanism includes:

[0051] The first motor 72a, the first screw 72b, the first slider 72c, the coupling, and the slider seat plate. The first moving component 73 is provided with a first slide rail 73a. The first slider 72c is slidably connected with the first slide rail 73a and fixed below the slider seat plate 71. The first motor 72a is arranged on the first moving component 73 and is driven and connected with the first screw 72b through the coupling. The first screw 72b is connected with the screw nut on the slider seat plate 71. Under the action of the first motor 72a, the first moving component 73 performs a lateral reciprocating motion under the action of the first slider 72c and the first slide rail 73a.

[0052] The second transmission mechanism 74 has the same structure as the first transmission mechanism, and the second transmission mechanism 74 drives the second moving component 75 to move horizontally on the first moving component 73 .

[0053] The above longitudinal setting method can fully utilize the longitudinal space of the leather cutting machine while retaining the original maximum transmission stroke.

[0054] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
