[0003] Among them, the shoe upper heating machine is a shoe upper heating machine disclosed in the invention with application number "201921970689.5", including a workbench, on which a heating zone and a loading and unloading zone are provided, the loading and unloading zone is located above the workbench, a heating device is provided on the heating zone, and the heating zone is located below the workbench. A conveying track is provided on the workbench, a part of the conveying track is located in the heating zone, and the other part is located in the loading and unloading zone, a conveying chain that can be transmitted along the conveying track is provided in the conveying track, and a driving member that can drive the conveying chain to transmit is also provided on the workbench.

[0004] The upper heating machine can meet the placement requirements of a relatively small space by dividing the heating area and the loading and unloading areas into upper and lower layers, thereby solving the problem of insufficient placement space and improving production efficiency.

[0005] A freezing setting machine, such as the one disclosed in the invention patent with application number "201110397982.9", has an evaporator on the inner surface of the top plate, a gas flow channel is preset in the central upper half and a cold exhaust fan is arranged in the lower half, the refrigeration system reduces the temperature of the gas flow channel and blows it downwards to the top, which is a concave-shaped conveying crawler with the center lower than the two sides, the crawler is composed of a chain connecting the two ends of a plurality of triangular plates with pointed ends, and the crawler is repeatedly rotated in one direction by a gear set along the corresponding track, and there is a gap between the shelves, and a ︺-shaped partition with the center lower than the two sides is also provided in the center of the crawler and close to the crawler; the refrigeration system reduces the temperature of the gas in the gas flow channel to form cold gas, which is blown downwards through the cold exhaust fan, and cooperates with the concave-shaped conveying crawler to gradually lower the shoe body fed in from high to the central low point, and it will naturally accumulate the cold gas in the center, thereby increasing the speed of low-temperature setting of the shoe body, providing local extremely low temperature, and enhancing the refrigeration cycle effect.

[0006] However, the above-mentioned upper heating machine and freezing and shaping machine need to be placed separately and cannot be stacked with other equipment. In addition to the space for injection molding machines and shoe packaging, assembling a shoe production line still requires a large amount of space. Summary of the invention

[0007] In view of the shortcomings of the prior art, the object of the present invention is to provide an all-in-one hot and cold setting machine which can heat the shoe upper and cold set the shoe.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A hot and cold setting integrated machine comprises a workbench, wherein a hot loading and unloading area is provided on the upper side of the workbench, a heating area is provided on the lower side of the workbench, a hot transfer track for conveying shoe lasts is provided on the workbench, a part of the hot transfer track is located in the hot loading and unloading area, and another part is located in the heating area. The characteristic is that a cold loading and unloading area is provided on the upper side of the workbench, a cold setting area is provided on the lower side of the workbench, the cold setting area is arranged around the outside of the heating area, a cold transfer track for conveying shoe lasts is provided on the workbench, a part of the transfer track is located in the cold setting area, and another part is located in the cold loading and unloading area.

[0010] The hot and cold setting integrated machine uses two independent conveying tracks to convey cold-set and hot-set shoe lasts respectively. At the same time, a part of the cold conveying track is located in the cold setting area below the workbench, and the other part is located in the cold loading and unloading area above the workbench. A part of the hot conveying track is located in the heating area below the workbench, and the other part is located in the hot loading and unloading area above the workbench. This design makes full use of the space above and below the workbench, and by surrounding the cold setting area around the outside of the heating area, the cold setting area and the heating area are located below the workbench at the same time, but can still work without interfering with each other, so that the hot and cold setting integrated machine can simultaneously perform hot setting on the upper and cold setting on the shoes, realizing multiple uses of one machine, which can greatly reduce the floor space, improve the space utilization rate of the machine, and is conducive to reducing the production cost and site requirements of the enterprise and improving production efficiency.

[0011] In the above-mentioned hot and cold setting integrated machine, the cold loading and unloading area is located at the left or right end of the workbench and outside the hot loading and unloading area. The left or right end of the workbench is provided with a cold feed notch and a cold discharge notch for the cold conveying track to pass through. The cold feed notch and the cold discharge notch are respectively located on the front and rear sides of the same end of the workbench.

[0012] When heat-setting the shoe upper, the shoe upper must first be tied and fixed on the shoe last, and then the shoe last with the upper fixed thereon is transported to the heating area for heat-setting. Therefore, when loading the shoe, more workstations and more workers are required to fix the shoe upper on the shoe last to complete the loading action. Therefore, the loading area of ​​the shoe upper is generally arranged at the front or rear side of the workbench with a long straight section of the heat transfer guide rail, and its unloading area is located on the side opposite to the loading area; therefore, the hot and cold setting integrated machine arranges the cold loading and unloading area at the left or right end of the workbench to avoid interference between the cold loading and unloading area and the hot loading and unloading area during loading and unloading, and makes full use of the idle left or right end of the workbench during hot loading and unloading, further improving the space utilization rate; the design of the cold feeding notch and the cold discharging notch on the workbench is convenient for the cold transfer track to pass through, and at the same time, arranging them at the left and right ends of the workbench can also avoid the cold transfer track interfering with the hot loading and unloading at the part above the workbench, making the operation of the hot and cold setting integrated machine smoother and more efficient.

[0013] In the above-mentioned hot and cold setting integrated machine, the cold conveying track in the cold loading and unloading area includes a cold loading section and a cold unloading section, and the cold unloading section is provided with a cold driving device, which can drive the conveying chain in the cold conveying track to move from the cold unloading section to the cold loading section.

[0014] In the cold and hot shaping machine, only the cold unloading section of the cold conveying track located on the upper side of the workbench is straight, and the other parts are inclined or bent, which cannot well accommodate and connect the cold driving device.

[0015] In the above-mentioned hot and cold setting integrated machine, the cold loading section is U-shaped and protrudes from the side of the workbench, and the cold unloading section is horizontally arranged.

[0016] The cold loading section and the hot loading section in the cold and hot setting all-in-one machine are arranged opposite to each other. For example, the hot loading section is arranged on the front side above the workbench, and the cold loading section protrudes from the rear side of the workbench. This design can avoid interference between cold setting loading and hot setting loading, thereby improving production efficiency and space utilization. At the same time, the horizontally arranged cold unloading section is not only convenient for the staff to carry out unloading operations, but also can better install the cold drive device.

[0017] In the above-mentioned hot and cold setting integrated machine, the cold feed notch and the cold discharge notch are both provided with flexible baffles for covering them, a through hole is provided in the middle of the flexible baffle for the guide rail to pass through, and the flexible baffle is divided into several sub-baffles with the through hole as the center.

[0018] The flexible baffle can block the cold feed notch and the cold discharge notch, reducing the discharge of cold air in the cold setting area from the two notches, thereby reducing the power consumption of the refrigeration device, which is beneficial to saving resources and reducing the cost of cold setting.

[0019] In the above-mentioned hot and cold setting integrated machine, an inner partition and an outer partition are provided on the lower side of the workbench to separate the heating area from the cold setting area, and there is a gap between the inner partition and the outer partition.

[0020] The hot and cold setting integrated machine separates the heating zone and the cold setting zone by an inner partition and an outer partition. At the same time, the setting of the gap between the inner partition and the outer partition can form a heat-insulating layer composed of air between the two partitions, thereby reducing the heat exchange between the inner partition and the outer partition, so that the heating zone and the cold setting zone have better thermal insulation effect, which is beneficial to reducing the power consumption of heating and cooling; further, the above-mentioned inner partition and outer partition are both made of heat-insulating material, and the space between the inner partition and the outer partition is filled with porous heat-insulating material.

[0021] In the above-mentioned hot and cold setting integrated machine, the heat transfer track in the hot loading and unloading area includes a hot loading section and a hot unloading section, a preheating box for preheating the shoe upper is provided above the hot loading section, the hot unloading section is located on the back of the hot loading section, and a heat driving device is provided on the hot unloading section, and the heat driving device can drive the conveying chain in the heat transfer track to move from the hot unloading section to the hot loading section.

[0022] The design of the above-mentioned preheating box can preheat the shoe upper, making it easier for workers to fix the shoe upper on the shoe last, which is beneficial to improving production efficiency; the hot unloading section is located on the back of the hot loading section, that is, the two are arranged opposite to each other. This design separates the loading and unloading positions during the heat setting process, avoiding mutual interference between the loading and unloading processes, which can further improve work efficiency, and can also reserve operating space for the loading and unloading of cold setting, further improving the space utilization of this hot and cold setting all-in-one machine.

[0023] In the above-mentioned hot and cold setting machine, a refrigeration device is provided on the workbench, and a cooling pipe and a return pipe are provided between the refrigeration device and the cold setting area to connect the two. The cooling pipe can transport the cold air generated by the refrigeration device to the cold setting area, and the return pipe can draw the air with higher temperature in the cold setting area into the refrigeration device for re-cooling.

[0024] The hot and cold setting all-in-one machine is provided with a refrigeration device and matching cooling pipes and return pipes, which can not only keep the temperature in the cold setting area within a range suitable for cold setting, but also reduce the working intensity of the refrigeration device and improve resource utilization by recycling the higher air in the cold setting area for re-refrigeration.

[0025] In the above-mentioned hot and cold setting machine, the refrigeration device includes a compressor, a condenser, an evaporator and a cold fan. The evaporator, compressor and condenser are connected in sequence, and the coolant circulates among the three. A refrigeration box for placing the evaporator and the cold fan is provided on the workbench. The cooling pipe is connected to one end of the refrigeration box and the cold fan can blow air into the cooling pipe. The return pipe is connected to the other end of the refrigeration box.

[0026] In the above-mentioned hot and cold setting integrated machine, the other end of the return duct is provided with at least one air inlet, and the air inlet is located at the end of the cold setting zone close to the cold feed notch and / or the end of the cold setting zone close to the cold discharge notch, and each air inlet is located at the top of the cold setting zone. The other end of the cooling duct is provided with multiple air outlets, and the air outlets are arranged at intervals along the moving direction of the cold transfer track in the cold setting zone.

[0027] The above-mentioned air inlet is arranged at the top of the cold setting area. Due to the principle that hot air rises, the air sucked away from the air inlet is the part with higher temperature in the cold setting area. The design of multiple air outlets can keep the temperature in the cold setting area at a low level, and the temperature of each part is more uniform, thereby improving the cooling and setting effect.

[0028] In the above-mentioned cold and hot shaping integrated machine, the lower side surfaces of the cold transfer track and the hot transfer track are provided with slide grooves along their length directions, and shoe lasts are arranged at intervals below the cold transfer track and the hot transfer track along their length directions. The shoe lasts are fixedly connected to the conveying chain through shoe last brackets passing through the slide grooves. The conveying chain includes a vertical roller assembly and a transverse roller assembly connected in sequence. The vertical roller assembly includes two connecting plates and a transverse axis. The transverse axis simultaneously passes through the middle parts of the two connecting plates, and vertical rollers are rotatably provided at both ends of the transverse axis. The distance between the two vertical rollers is greater than the width of the slide groove, the upper end of the shoe last bracket is connected to the middle part of the horizontal axis, and both ends of the two connecting plates are fixedly connected with a connecting shaft for connecting the two connecting plates. The transverse roller assembly includes a vertical axis and a horizontally arranged transverse roller and two mounting plates. The vertical axis passes through the transverse roller and the two ends of the vertical axis are rotatably connected to the middle parts of the two mounting plates respectively. The two ends of the two mounting plates are fixedly connected by an arc-shaped mounting portion, and the mounting portion passes through the vertical roller assembly vertically and is located between the transverse axis and the connecting axis.

[0029] The vertical roller assembly of the above-mentioned conveyor chain can make the conveyor chain move relative to the corresponding cold conveyor track or hot conveyor track, and play a supporting role for the shoe last bracket. Since the cold conveyor track and the hot conveyor track are both multi-layer tracks, they have many arc-shaped corners. The transverse roller assembly can make the conveyor chain roll relative to the side wall of the corresponding conveyor track at the corner, thereby avoiding sliding friction between the conveyor chain and the corresponding conveyor track, so that the conveyor chain can move more smoothly in the corresponding conveyor track; the distance between the above-mentioned two vertical rollers is greater than the width of the slide groove, which can ensure that the conveyor chain can move smoothly along the corresponding conveyor track, avoid the vertical roller from falling into the slide groove and affecting the normal operation of the conveyor chain, and make the transmission smoother; further, the distance between the inner side wall of the vertical roller and the inner side wall of the conveying track on the other side of the slide groove is greater than the distance between the slide groove wall on the same side as the vertical roller and the inner side wall of the conveying track on the other side.

[0030] In the above-mentioned hot and cold setting machine, the cold drive device and the hot drive device both include a drive motor and two drive gears, the drive motor is connected to one of the drive gears and can drive the drive gear to rotate, the two drive gears are connected by a meshing drive chain, and the outer side of the drive chain is provided with a convex tooth that can mesh with the vertical roller assembly on the conveying chain.

[0031] The above two driving devices both drive the driving gear to rotate through the driving motor, and then drive the driving chain to rotate through the driving gear, and drive the conveyor chain to rotate by engaging the convex teeth arranged on the driving chain with the vertical roller assembly of the conveyor chain, so that the transmission is smoother and more stable.

[0032] Compared with the prior art, the technical effects of the present invention are:

[0033] The hot and cold setting integrated machine uses two independent conveying tracks to convey cold-set and hot-set shoe lasts respectively. At the same time, a part of the cold conveying track is located in the cold setting area below the workbench, and the other part is located in the cold loading and unloading area above the workbench. A part of the hot conveying track is located in the heating area below the workbench, and the other part is located in the hot loading and unloading area above the workbench. This design makes full use of the space above and below the workbench, and by surrounding the cold setting area around the outside of the heating area, the cold setting area and the heating area are located below the workbench at the same time, but can still work without interfering with each other, so that the hot and cold setting integrated machine can simultaneously perform hot setting on the upper and cold setting on the shoes, realizing multiple uses of one machine, which can greatly reduce the floor space, improve the space utilization rate of the machine, and is conducive to reducing the production cost and site requirements of the enterprise and improving production efficiency.

At the same time, a part of the cold conveying track 22 is located in the cold-setting area 13 below the workbench 1, and the other part is located in the cold loading and unloading area 14 above the workbench 1. A part of the hot conveying track 21 is located in the heating area 11 below the workbench 1, and the other part is located in the hot loading and unloading area 12 above the workbench 1. This design makes full use of the space above and below the workbench 1, and by surrounding the cold-setting area 13 around the outside of the heating area 11, the cold-setting area 13 and the heating area 11 are located below the workbench 1 at the same time, but can still work without interfering with each other, so that the hot and cold setting integrated machine can simultaneously perform hot-setting on the upper and cold-setting on the shoes, realizing multiple uses of one machine, which can greatly reduce the floor space, improve the space utilization rate of the machine, and is conducive to reducing the production cost and site requirements of the enterprise and improving production efficiency.

[0043] In the above-mentioned hot and cold setting integrated machine, the cold loading and unloading area 14 is located at the left end or the right end of the workbench 1 and at the outside of the hot loading and unloading area 12. The left end or the right end of the workbench 1 is provided with a cold feed notch 15 and a cold discharge notch 16 for the cold conveying track 22 to pass through. The cold feed notch 15 and the cold discharge notch 16 are respectively located at the front and rear sides of the same end of the workbench 1; the cold conveying track 22 in the cold loading and unloading area 14 includes a cold loading section 221 and a cold unloading section 222, and the cold unloading section 222 is provided with a cold driving device 32, and the cold driving device 32 can drive the conveying chain 24 in the cold conveying track 22 to move from the cold unloading section 222 to the direction of the cold loading section 221; the cold loading section 221 is U-shaped and protrudes from the side of the workbench 1, and the cold unloading section 222 is horizontally arranged.

[0044] When heat-setting the shoe upper, the shoe upper must first be tied and fixed on the shoe last 51, and then the shoe last 51 with the shoe upper fixed thereon is transported to the heating zone 11 for heat-setting. Therefore, when loading the materials, more workstations and more workers are required to fix the shoe upper on the shoe last 51 to complete the loading action. Therefore, the loading area of ​​the shoe upper is generally arranged on the front side or rear side of the workbench 1 with a long straight section of heat transfer guide rail, and its unloading area is located on the side opposite to the loading area; therefore, the hot and cold setting integrated machine arranges the cold loading and unloading area 14 at the left end or right end of the workbench 1 to avoid interference between the cold loading and unloading area 14 and the hot loading and unloading area 12 during loading and unloading, and makes full use of the left end or right end of the workbench 1 that is idle during hot loading and unloading, further improving the space utilization rate; the design of the cold feeding notch 15 and the cold discharging notch 16 on the workbench 1 facilitates the passage of the cold transfer track 22, and at the same time, it is arranged on the left side of the workbench 1 The end and the right end can also prevent the cold transfer track 22 from interfering with the hot loading and unloading on the part above the workbench 1, making the operation of the hot and cold setting machine smoother and more efficient; in the hot and cold setting machine, only the cold unloading section 222 of the cold transfer track 22 located on the upper side of the workbench 1 is straight, and the other parts are inclined or bent, which cannot be well placed and connected to the cold driving device 32; the cold loading section 221 and the hot loading section 211 in the hot and cold setting machine are arranged opposite to each other. For example, the hot loading section 211 is arranged on the front side above the workbench 1, and the cold loading section 221 protrudes from the rear side of the workbench 1.

[0050] The vertical roller assembly 241 of the conveyor chain 24 can move the conveyor chain 24 relative to the corresponding cold conveyor track 22 or hot conveyor track 21, and play a supporting role for the shoe last bracket 52. Since the cold conveyor track 22 and the hot conveyor track 21 are both multi-layer tracks, they have many arc-shaped corners. The horizontal roller assembly 242 can make the conveyor chain 24 roll relative to the side wall of the corresponding conveyor track at the corner, thereby avoiding sliding friction between the conveyor chain 24 and the corresponding conveyor track, so that the conveyor chain 24 can move relative to the corresponding conveyor track. The distance between the two vertical rollers 2413 is greater than the width of the slide groove 23, which can ensure that the conveyor chain 24 can move smoothly along the corresponding conveyor track, avoid the vertical roller 2413 from falling into the slide groove 23 and thus affect the normal operation of the conveyor chain 24, and make the transmission smoother; further, the distance between the inner side wall of the vertical roller 2413 and the inner side wall of the conveying track on the other side of the slide groove 23 is greater than the distance between the groove wall of the slide groove 23 on the same side as the vertical roller 2413 and the inner side wall of the conveying track on the other side.

[0051] Furthermore, the cold drive device 32 and the hot drive device 31 each include a drive motor 33 and two drive gears 34. The drive motor 33 is connected to one of the drive gears 34 and can drive the drive gear 34 to rotate. The two drive gears 34 are connected through a meshing drive chain 35. The outer side of the drive chain 35 is provided with a convex tooth 351 that can mesh with the vertical roller assembly 241 on the conveying chain 24. The above two drive devices drive the drive gear 34 to rotate through the drive motor 33, and then drive the drive chain 35 to rotate through the drive gear 34. The convex tooth 351 provided on the drive chain 35 meshes with the vertical roller assembly 241 of the conveying chain 24 to drive the conveying chain 24 to rotate, and the transmission is smoother and more stable.
