Description

Technical Field

[0001] This invention belongs to the technical field of bag production equipment, and specifically relates to a bag production and processing equipment. Background Technology

[0002] When producing bags containing leather, leather is required. Before using leather to produce bags, the leather usually needs to be smoothed to ensure product quality.

[0003] Currently, the leather is usually smoothed by directly pressing and ironing it with a heated ironing roller.

[0004] However, leather to be flattened usually has wrinkles. When the wrinkled areas are pressed and ironed by the ironing roller, they are squeezed and overlapped together, resulting in creases after flattening and thinning of the creases, which affects the subsequent use of the leather.

[0005] Currently, two side rollers are usually installed upstream of the ironing roller and on both sides of the conveyor belt to apply outward pulling force to the leather on the conveyor belt, pulling out the wrinkles. Then, the leather is squeezed and ironed by the ironing roller, which can effectively improve the situation of creases appearing after flattening.

[0006] However, the side rollers are usually a certain distance from the ironing rollers, and the leather may wrinkle again during the process of being stretched by the side rollers and entering the ironing rollers; moreover, the side rollers only apply tension to the leather to both sides. Therefore, the stretching effect is better for wrinkles in the same direction as the conveying direction, but the stretching effect is not ideal for wrinkles perpendicular to the conveying direction. Summary of the Invention

[0007] This invention provides a bag manufacturing and processing equipment, which aims to solve the technical problem in the prior art that leather may wrinkle again during the process of being stretched by the side rollers and entering the ironing rollers; and that the side rollers have a better stretching effect on wrinkles in the same direction as the conveying direction, but a poorer stretching effect on wrinkles perpendicular to the conveying direction.

[0027] A first valve core is slidably disposed in the first valve body, and one end facing the air nozzle is adapted to abut against the first valve body and is provided with a second magnet, the second magnet repelling the annular magnet.

[0059] Please refer to the following: Figures 1 to 5The bag production and processing equipment provided by the present invention will now be described. The bag production and processing equipment includes a support 11 and a leveling component. A flat plate 12 is provided on the upper side of the support 11, and the leather 50 to be leveled is placed on the flat plate 12. The leveling component includes a conveying component, a plurality of elastic bladders 30 and an inflation component. The conveying component is located on the upper side of the flat plate 12 and is connected to the support 11. The conveying component is provided with a conveyor belt 25 connected end to end, and the conveyor belt 25 on the lower side of the conveying component is planar. A plurality of elastic bladders 30 are arranged along the conveying direction of the conveyor belt 25, one side is connected to the conveyor belt 25, and the other side is adapted to press against the leather 50. Each elastic bladder 30 is provided with an air nozzle 31 on one side. The inflation component is located on one side of the conveying component and is connected to the support 11. The inflation component is adapted to inflate the elastic bladders 30 that move to the upper side of the leather 50 with high-temperature gas.

[0060] The beneficial effects of the bag production and processing equipment provided in this embodiment of the invention are as follows: Compared with the prior art, the bag production and processing equipment provided in this embodiment of the invention, through the conveying component, drives the elastic bladder 30 to move to the upper side of the leather 50, aligning the air nozzle 31 with the air inlet of the inflation component. Then, the inflation component is activated to inflate the elastic bladder 30 with high-temperature gas. The elastic bladder 30 presses against the leather 50 and begins to expand. Then, through friction, the leather 50 is stretched and unfolded in all directions. During the expansion process, the temperature gradually increases, which can effectively stretch the wrinkles in all directions. While keeping the leather 50 stretched in all directions, the high-temperature elastic bladder 30 is used to iron the leather 50. This can effectively solve the technical problems in the prior art where the leather 50 wrinkles again during the process of being stretched by the side rollers and entering the ironing rollers, and the poor stretching effect for wrinkles perpendicular to the conveying direction.

[0061] like Figure 1 and Figure 2 As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, the conveying assembly includes a drive roller 21, a driven roller 22, a drive assembly 23, and a conveyor belt 25. Both ends of the drive roller 21 are rotatably connected to the support 11. The driven roller 22 is located upstream or downstream of the drive roller, and both ends are rotatably connected to the support 11. The drive assembly 23 is connected to the support 11, and its power output end is connected to one end of the drive roller 21 to drive the drive roller 21 to rotate. The conveyor belt 25 is sleeved on the drive roller 21 and the driven roller 22.

[0062] Specifically, the driven roller 22 is located upstream of the driving roller 21, and the driving assembly 23 drives the driving roller 21 to rotate, thereby driving the conveyor belt 25 to move.

[0063] like Figure 2 and Figure 3As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, the conveying assembly further includes a support plate 24. The support plate 24 is disposed inside the conveyor belt 25 and connected to the bracket 11. The support plate 24 abuts against the inner side of the lower conveyor belt 25 to provide support force to the lower conveyor belt 25.

[0064] like Figure 1 and Figure 2 As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, two adjacent elastic bladders 30 are fitted together, and the length of each elastic bladder 30 in the conveying direction is less than or equal to the length of the conveyor belt 25 located on the lower side of the conveying assembly and in a planar shape, so as to ensure that the leather 50 is flattened without gaps.

[0065] like Figure 3 and Figure 4 As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, each air nozzle 31 is provided with an annular magnet 32 ​​at its outer end. The inflation assembly includes a connecting pipe 41, a first valve, and a spring 51. The connecting pipe 41 is arranged horizontally and connected to the bracket 11. One end is adapted to communicate with an air source through an air pipe. One end of the first valve is sleeved on the connecting pipe 41 and is slidably sealed to the connecting pipe 41. The other end is adapted to be attracted by the annular magnet 32. The spring 51 is sleeved on the connecting pipe 41, with one end connected to the first valve and the other end connected to the bracket 11.

[0066] It should be noted that an annular magnet 32 ​​is provided at its outermost end. When the air nozzle 31 moves to a position aligned with one of the first valves, the annular magnet 32 ​​automatically attracts the first valve, causing the air nozzle 31 and the first valve to fit together. Then, air can be injected into the elastic bladder 30. During the inflation process, the elastic bladder 30 expands outward and squeezes the first valve outward. The first valve slides outward along the connecting pipe 41, and the spring 51 is compressed. Until leveling is completed, the conveyor belt 25 continues to drive the elastic bladder 30 forward. The air nozzle 31 and the first valve are misaligned and disconnected. The first valve is reset under the action of the spring 51.

[0067] like Figure 3 and Figure 4 As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, the first valve includes a first valve body 42 and a first valve core 44. One end of the first valve body 42 is sleeved on the connecting pipe 41, slides and seals with the connecting pipe 41 and communicates with the connecting pipe 41. The other end of the first valve body 42 is provided with an iron ring 43, which is suitable for being attracted by an annular magnet 32 ​​to make the first valve body 42 communicate with the air nozzle 31. The first valve core 44 is slidably disposed in the first valve body 42, and the end facing the air nozzle 31 is suitable for abutting against the first valve body 42 and is provided with a second magnet 45, which repels the annular magnet 32.

[0068] It should be noted that before the air nozzle 31 is attached to the first valve, the first valve core 44 is in contact with the first valve body 42 under the attraction of the second magnet 45 to the iron ring 43, and the first valve is in the closed state. When the air nozzle 31 is attached to the first valve, the annular magnet 32 ​​attracts the iron ring 43 and generates a repulsive force on the second magnet 45, causing the first valve core 44 to slide away from the annular magnet 32 ​​and open the first valve. That is, the first valve can automatically open when connected to the air nozzle 31 and automatically close when separated from the air nozzle 31.

[0069] like Figure 3 and Figure 4 As shown, in a specific embodiment of the bag manufacturing equipment provided in this invention, the inflation assembly further includes an inflation plate 46 and an annular belt 49. The inflation plate 46 is located on one side of the conveying assembly and connected to the bracket 11. The inflation plate 46 has an air chamber inside and an annular groove communicating with the air chamber is opened on the side facing the conveying assembly. The upper and lower sides of the annular groove are both straight, and the two ends are semi-circular and located on the outer sides of the two ends of the conveyor belt 25. The air chamber is connected to an air source through an air pipe. The annular belt 49 is embedded in the annular groove and slides in cooperation with the inflation plate 46. The annular belt 49 has multiple connecting pipes on the side facing away from the inflation plate 46. 41. Connecting pipe 41 is connected to air chamber. Each connecting pipe 41 is fitted with a first valve and spring 51. The upper and lower sides of the conveyor belt 25 on the conveyor assembly are straight, and the two ends are semi-circular. The air nozzles 31 on several elastic bladders 30 on the straight conveyor belt 25 are aligned with the first valves on the straight annular belt 49 and move synchronously. During the movement of the elastic bladders 30, air is inflated inside, so that the elastic bladders 30 gradually expand as they press the leather 50 forward, flattening the leather 50 without having to stop the movement to flatten the leather 50, thus improving work efficiency.

[0070] like Figure 1 and Figure 2 As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, the length of each elastic bladder 30 in the conveying direction is less than or equal to half the length of the flat conveyor belt 25 located below the conveying assembly. Preferably, the length of the elastic bladder 30 in the conveying direction is less than or equal to one-quarter of the length of the flat conveyor belt 25 located below the conveying assembly, so that the elastic bladder 30 pressing the leather 50 has sufficient time to expand and stretch the leather 50, flatten the leather 50, and ensure the flattening quality.

[0071] like Figure 3As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, the air chamber is divided into a high-temperature air chamber 47 and a normal-temperature air chamber 48. The high-temperature air chamber 47 is located below the normal-temperature air chamber 48 and is isolated from the normal-temperature air chamber 48. The connecting pipe 41 that moves to the upper straight part of the annular belt 49 is connected to the normal-temperature air chamber 48, and the connecting pipe 41 that moves to the lower straight part of the annular belt 49 is connected to the high-temperature air chamber 47.

[0072] It should be noted that the elastic bladder 30 is at a high temperature after the leveling operation. If it remains at a high temperature when it comes into contact with the leather 50 again, it may directly iron the wrinkled leather 50, resulting in deep creases. Therefore, a normal temperature air chamber 48 is provided so that when the elastic bladder 30 moves from the lower side of the conveyor belt 25 to the upper side of the conveyor belt 25 after the leveling operation, it connects with the normal temperature air chamber 48, and normal temperature gas is introduced into the elastic bladder 30 to cool it down.

[0073] Furthermore, such as Figure 3 and Figure 5 As shown, in a specific embodiment of the bag production and processing equipment provided in this invention, each elastic bladder 30 is provided with a second valve on the side facing away from the air nozzle 31. The second valve includes a second valve body 33 and a second valve core 34. One end of the second valve body 33 is provided with an air inlet, and the side is provided with an air outlet. The second valve body 33 has a cavity inside, one side of which is connected to the air inlet, and the bottom is conical and connected to the air outlet. The second valve body 33 is connected to the elastic bladder 30, and the air inlet is connected to the elastic bladder 30. The second valve core 34 is located in the cavity and is suitable for blocking the bottom of the cavity.

[0074] It should be noted that when the second valve moves to the second valve body 33 inside the elastic bladder 30 on the conveyor belt 25 (which has a straight structure and is located below the conveyor assembly), the second valve core 34 slides down to the bottom of the cavity under gravity, blocking the bottom of the cavity and disconnecting the air inlet and outlet to prevent high-temperature gas from escaping from the second valve. When the second valve core 34 moves to the second valve body 33 inside the elastic bladder 30 on the conveyor belt 25 (which has a straight structure and is located above the conveyor assembly), it slides away from the bottom of the cavity under gravity, connecting the air inlet and outlet. At this time, the air nozzle 31 connects to the ambient temperature air chamber 48, allowing ambient temperature gas to be blown into the elastic bladder 30 and discharged from the second valve, carrying away the heat from the elastic bladder 30 and increasing the cooling rate. Specifically, the second valve core 34 has a spherical structure.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
