Description

Technical Field

[0001] The utility model relates to the field of leather cutting equipment, in particular to a leather cutting machine with a double-section suspension beam. 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] According to paragraph 0022 of the specific implementation scheme of its specification: "An X-axis slide rail 34 is provided at the bottom of the X-axis slide 31, and the tool assembly 32 is installed on the X-axis slide rail 34. The X-axis slide 31 is provided with an X-axis motor for driving the tool assembly 32 to slide along the X-axis slide rail 34;" and paragraph 0027 of the specific implementation scheme "The control module controls the operation of the Y-axis motor and the X-axis motor on the cloth cutting station 3, and the X-axis motor drives the tool assembly 32 to slide along the X-axis slide rail 34."

[0004] It can be seen that the X-axis slide rail must have a length that allows the tool assembly to reach any point in the X-axis direction. However, the current X-axis slide rail of this type of cutting machine is a single one, and its length is designed based on the actual stroke, without considering a larger stroke in less space. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a leather cutting machine with a double-section suspension beam, which can meet the basic condition of maximum stroke in a limited space and reduce the space occupancy rate.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A leather cutting machine with a double-section suspension beam, wherein a cutting head is arranged above the cutting area of ​​the main body, and is characterized in that the cutting head is arranged on the double-section suspension beam assembly, wherein the double-section suspension beam assembly is a linear moving module installed on another linear moving module through a moving part, any linear moving module drives the moving part to move, so that the other linear moving module moves, and the cutting head is driven by the other linear moving module to perform reciprocating motion, and the linear moving modules are kept in a posture with opposite or same moving directions.

[0008] Furthermore, the linear motion modules are respectively mounted on two opposite surfaces of the moving component.

[0009] Furthermore, there is a linear motion module including a motor, a screw, a slider, a coupling, and a slider seat plate. A slide rail is provided on the surface of the moving part. The slider is slidably connected to the slide rail. The slider seat plate is installed on the slider. The motor is arranged on the moving part and is connected to the screw drive through a coupling. The screw is connected to the lead screw nut on the slider seat plate. Under the action of the motor, the moving part performs lateral reciprocating motion under the action of the slider and the slide rail.

[0010] Furthermore, the main body includes a frame and a driven roller supporting the cutting pad on the frame. The end of the frame along the length direction is a foldable folding body. The driven roller is arranged on the folding body, which can reduce the distribution of the cutting pad along the length direction of the frame through the rotation of the folding body.

[0011] Furthermore, the folding body includes a support plate and a rotating shaft. The support plate is provided with an opening structure. The rotating shaft passes through the opening structure, and the support plate is installed on the frame.

[0012] Furthermore, the opening structure is composed of two parts connected to each other, namely a positioning part having a pair of first planes on the inner circumference and an adjusting part having a first curved surface. The rotating shaft has a geometric shape matching the waist-shaped hole and the top and bottom surfaces of the rotating shaft in the positioning part are against the first plane. Constrained by the first plane, the support plate is in a positioned state, and the rotating shaft is moved into the adjusting part by translation. After the second curved surfaces at both ends of the rotating shaft match the first curved surface, they rotate under their own gravity to form a folded and stored state.

[0013] Furthermore, it also includes a material receiving table, which is installed on the supporting plate.

[0014] Furthermore, it also includes screws, and the surface of the rotating shaft is provided with screw holes, and the screws pass through the screw holes and are connected to the frame.

[0015] Beneficial effects of the utility model:

[0016] The double-section suspension beam assembly of the utility model combines two linear movable modules on the same moving part, and at least one linear movable module drives the moving part to move. This superimposed installation method can reduce the overall volume size. The problem of ignoring space occupancy in the prior art can be solved by the double-section suspension beam assembly. In other words, in addition to retaining the original maximum transmission stroke, the longitudinal space of the leather cutting machine can also be fully utilized. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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.

[0034] like Figure 1-16As shown, in this embodiment, a leather cutting machine with a double-section suspension beam 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] The specific usage is as follows:

[0049] 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.

[0050] 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.

[0051] 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.

[0052] In an embodiment, the linear motion mechanism includes a double-section suspension beam assembly, which includes a fixed platform 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:

[0053] 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.

[0054] 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 .

[0055] The above longitudinal setting method can fully utilize the longitudinal space of the leather cutting machine while retaining the original maximum transmission stroke.

[0056] 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.
