Description

Technical Field

[0001] This utility model relates to the field of edge-binding technology for leather case making machines, and more specifically to an automatic double-sided folding edge-binding mechanism for a fully automatic leather case making machine. Background Technology

[0002] In the modern packaging industry, the requirements for the packaging quality of products such as book covers and hardcover gift boxes are getting higher and higher. Traditional manual packaging methods are inefficient and it is difficult to guarantee the consistency and accuracy of packaging. With the market's dual demand for the quantity and quality of packaging products, fully automatic shell wrapping machines have emerged. They can quickly complete the edge wrapping of one shell and immediately start the edge wrapping of the next shell, which greatly improves the efficiency of the entire production process.

[0003] Existing shell-making machines mostly use wheeled edge-wrapping operations, which can easily cause the shells to be squeezed and stacked. This mutual squeezing and stacking of the shells will destroy their original shape and structure, thus adversely affecting the overall molding quality of the shell.

[0004] In addition, existing leather shell machines mostly rely on manual labor to remove the finished leather shells after the edge binding is completed. This manual removal method not only requires a lot of labor costs, but also has relatively limited speed. When facing large-scale and continuous production needs, the overall production efficiency will be low, making it difficult to meet the requirements of high-efficiency production.

[0005] To address the aforementioned issues, this application provides an automatic double-sided folding and hemming mechanism for a fully automatic casing machine. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides an automatic double-sided folding and binding mechanism for a fully automatic leather case machine, so as to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: an automatic double-sided folding and hemming mechanism for a fully automatic shell-making machine, including a shell assembly and conveying assemblies installed on both sides of the shell assembly. The shell assembly is provided with a pushing assembly and a pressing assembly. A transmission folding assembly is installed on the pushing assembly, and a release assembly is provided below the pressing assembly.

[0008] Preferably, the housing assembly includes a main housing, an inlet and an outlet, wherein the inlet and outlet are fixedly installed at the through holes on the left and right sides of the main housing, respectively.

[0009] Preferably, the conveying assembly includes a first rotary motor, an upper rod, a lower rod, a conveying roller, and gears. The first rotary motor is fixedly installed on the side wall of the main housing. The drive shaft of the first rotary motor movably passes through the main housing and is fixedly sleeved on the upper rod. The conveying roller is fixedly sleeved on the middle section of the upper rod and the lower rod. The lower rod is disposed below the upper rod and rotatably sleeved on the inner wall of the main housing. Gears are fixedly sleeved on the ends of the upper rod and the lower rod away from the first rotary motor. The two gears mesh with each other. At this time, the drive shaft of the first rotary motor drives the corresponding upper rod to rotate, and drives the lower rod to rotate through the meshing action between the gears.

[0010] Preferably, the pressing assembly includes a first pressure plate, a second pressure plate, a positioning plate, a limiting member, a linkage plate, a tightening plate, and a first telescopic motor. The positioning plate is fixedly installed on both sides of the inner wall of the main housing. The first pressure plate and the second pressure plate intersect and are disposed on the positioning plate. The limiting members are fixedly installed in pairs on the positioning plate. The linkage plate slidably connects the two limiting members. The tightening plate is fixedly installed at the opening in the middle section of the linkage plate. The first telescopic motor is fixedly installed on the positioning plate. The telescopic shaft of the first telescopic motor is fixedly connected to the tightening plate. At this time, the telescopic shaft of the first telescopic motor drives the tightening plate and the linkage plate to move towards the center, and pushes the second pressure plate towards the center to press the housing through the transmission folding assembly.

[0011] Preferably, the transmission folding assembly includes a first transmission component, a second transmission component, a fixing component, a locking pin, a sleeve, and a spring. The transmission folding assembly is integrally mounted on both sides of the second transmission component. One end of the first transmission component is fixedly sleeved with the hinge shaft at the connection between the first pressure plate and the second pressure plate, and the other end is rotatably connected to the second transmission component. The end of the first pressure plate near the second pressure plate is fixedly sleeved with the hinge shaft, and the end of the second transmission component away from the first transmission component is rotatably connected to the fixing component. One end of the fixing component is fixedly connected to the linkage plate, and the other end is movably locked with the sleeve. The spring is disposed in the locking cavity formed by the locking pin and the spring. The sleeve is fixedly mounted on the second pressure plate. When the second pressure plate completely abuts against both sides of the leather shell, the locking pin compresses the spring, and the fixing component is driven to move towards the center. This, in turn, drives the first transmission component and the first pressure plate to rotate along the hinge shaft with the second pressure plate through the second transmission component, thereby performing a secondary folding of the leather shell.

[0012] Preferably, the pressing assembly includes a top plate, a square slot, a sensor, a second telescopic motor, and a pressing component. The second telescopic motor is fixedly installed at the top of the inner cavity of the main housing. The telescopic shaft of the top plate is fixedly connected to the pressing component. The top plate is located directly below the pressing component and is fixedly installed at the bottom of the inner cavity of the main housing. A square slot is provided at the bottom left side of the top plate. The sensor is fixedly installed at the left end of the top plate. When the sensor detects that the upper shell is in place, the telescopic shaft of the second telescopic motor drives the pressing component to press down and engage with the top plate, so that the two sides of the shell fold at a 90-degree angle.

[0013] Preferably, the ejection assembly includes a positioning seat, a rotating roller, a transmission wheel, a toothed belt, a second rotating motor, a limiting seat, and a third telescopic motor. The ejection assembly is positioned directly below the square slot. The rotating roller is rotatably sleeved on both sides above the positioning seat. The second rotating motor is fixedly mounted on the positioning seat. Transmission wheels are fixedly sleeved on the transmission shafts of both the rotating roller and the second rotating motor. The toothed belt is wound between the three transmission wheels. The positioning seat is slidably connected to the third telescopic motor. The third telescopic motor is fixedly mounted between the positioning seat and the third telescopic motor. The limiting seat is fixedly mounted at the bottom of the inner cavity of the main housing. At this time, the third telescopic motor pushes the positioning seat upward until the rotating roller lifts the housing. The transmission shaft of the second rotating motor drives the lower transmission wheel to rotate, and drives the other two transmission wheels to rotate through the toothed belt. At this time, the two rotating rollers are also driven to rotate, lifting the housing and bringing it out from the top plate.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] The push assembly, in conjunction with the transmission folding assembly, can efficiently and quickly fold and edge the leather case, effectively improving edge-wrapping efficiency. In addition, the release assembly can effectively and quickly release the edged leather case and send it out of the device, avoiding the inefficient operation of manual removal.

The ends of the upper rod 202 and the lower rod 203 away from the first rotary motor 201 are fixedly sleeved with gears 205. The two gears 205 mesh with each other. At this time, the drive shaft of the first rotary motor 201 drives the corresponding upper rod 202 to rotate, and drives the lower rod 203 to rotate through the meshing action between the gears 205.

[0027] Reference Figure 2 The pressing assembly 3 includes a first pressing plate 301, a second pressing plate 302, a positioning plate 303, a limiting member 304, a linkage plate 305, a tightening plate 306, and a first telescopic motor 307.

When the second pressure plate 302 completely abuts against both sides of the leather shell, the engagement post 404 squeezes the spring 406, and the fixing member 403 is driven to move towards the center. Then, through the second transmission member 402, the first transmission member 401 and the first pressure plate 301 are driven to rotate along the hinge axis with the second pressure plate 302, thereby performing a second folding of the leather shell.

[0029] Reference Figure 2 and Figure 4 The pressing component 5 includes a top plate 501, a square slot 502, a sensor 503, a second telescopic motor 504, and a pressing member 505. The second telescopic motor 504 is fixedly installed on the top of the inner cavity of the main housing 101. The telescopic shaft of the top plate 501 is fixedly connected to the pressing member 505. The top plate 501 is located directly below the pressing member 505 and is fixedly installed at the bottom of the inner cavity of the main housing 101. A square slot 502 is opened on the bottom left side of the top plate 501. The sensor 503 is fixedly installed on the left end of the top plate 501. When the sensor 503 detects that the upper shell is in place, the telescopic shaft of the second telescopic motor 504 drives the pressing member 505 to press down and engage with the top plate 501, so that the two sides of the shell are folded at a ninety-degree angle.

[0030] Reference Figure 2 and Figure 4-5The release assembly 6 includes a positioning seat 601, a rotating roller 602, a transmission wheel 603, a toothed belt 604, a second rotary motor 605, a limiting seat 606, and a third telescopic motor 607. The release assembly 6 is positioned directly below the square slot 502. The rotating roller 602 is rotatably sleeved on both sides above the positioning seat 601. The second rotary motor 605 is fixedly mounted on the positioning seat 601. Transmission wheels 603 are fixedly sleeved on the transmission shafts of both the rotating roller 602 and the second rotary motor 605. The toothed belt 604 is wound between the three transmission wheels 603. The positioning seat 601... The third telescopic motor 607 is slidably connected and fixedly installed between the positioning seat 601 and the third telescopic motor 607. The limiting seat 606 is fixedly installed at the bottom of the inner cavity of the main housing 101. At this time, the third telescopic motor 607 pushes the positioning seat 601 to rise until the rotating roller 602 lifts the skin. The transmission shaft of the second rotating motor 605 drives the lower transmission wheel 603 to rotate, and drives the other two transmission wheels 603 to rotate through the toothed belt 604. At this time, the two rotating rollers 602 are also driven to rotate, lifting the skin and taking it out from the top plate 501.

[0031] The working principle of this utility model is as follows: The casing is placed between the two conveying rollers 204 on the right side. At this time, the transmission shaft of the first rotary motor 201 on the right side drives the corresponding upper rod 202 to rotate, and through the meshing action between the gears 205, it drives the lower rod 203 on the right side to rotate. Thus, the casing is sent into the main housing 101 through the conveying rollers 204 and brought to the top plate 501. When the sensor 503 detects that the upper casing is in place, the telescopic shaft of the second telescopic motor 504 drives the lower pressing member 505 to press down and engage with the top plate 501, so that the two sides of the casing are folded at a 90-degree angle. At this time, the telescopic shaft of the first telescopic motor 307 drives the tightening plate 306 and the linkage plate 305 to move towards the center, and pushes the second pressure plate 302 towards the center to squeeze the casing through the locking post 404 and the locking sleeve 405. When the second pressure plate 302 fully abuts against both sides of the shell, the locking post 404 compresses the spring 406, and the fixing member 403 is driven to move towards the center. Then, through the second transmission member 402, the first transmission member 401 and the first pressure plate 301 are driven to rotate along the hinge axis with the second pressure plate 302, thereby folding the shell a second time. After the folding is completed, the parts are reset, and the third telescopic motor 607 pushes the positioning seat 601 to rise until the rotating roller 602 lifts the shell. At this time, the transmission shaft of the second rotating motor 605 drives the lower transmission wheel 603 to rotate, and drives the other two transmission wheels 603 to rotate through the toothed belt 604. At this time, the two rotating rollers 602 are also driven to rotate, lifting the shell and bringing it out from the top plate 501. Then, it is brought out of the device through the left conveying assembly 2.
