Description

[Technical Field]

[0001] This utility model relates to the field of bottom pressing machine technology, and in particular to an improved bottom pressing machine. [Background Technology]

[0002] In the shoe manufacturing process, after the upper and sole are bonded together with fabric and adhesive, the bonded shoes need to be squeezed to ensure that the sole and upper fit tightly and are shaped, thereby ensuring the bonding effect between the sole and upper. This is where the sole pressing machine comes in.

[0003] Existing sole pressing machines typically include a frame, left and right edge pressing mechanisms, front and rear tightening mechanisms, and a pressure bar mechanism. The left and right edge pressing mechanisms and the front and rear tightening mechanisms are both located below the pressure bar mechanism, forming a cavity to accommodate the shoe. However, existing sole pressing machines require manual handling of shoes during operation, hindering automated production. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide an improved sole pressing machine, which solves the problem that existing sole pressing machines require manual handling of shoes during use, which is not conducive to achieving automated production.

[0006] A frame, wherein an installation space is formed in the middle of the frame;

[0007] Left and right pressing devices, at least one left and right pressing device is provided at the bottom of the installation space;

[0008] The front and rear tensioning devices are provided at the top of the installation space at the position corresponding to each left and right pressing device. The front and rear tensioning devices include a front tensioning mechanism, a rear tensioning mechanism, and a driving mechanism that drives the front tensioning mechanism and the rear tensioning mechanism to move closer to each other or further away from each other. Both the front tensioning mechanism and the rear tensioning mechanism include a mounting base that can be slidably mounted on the frame, a lifting component mounted on the mounting base, and a tensioning block located at the lower end of the lifting component.

[0009] A pressure bar device is provided at the top of the installation space at the position corresponding to each left and right pressure edge device, and the pressure bar device is located between the front tightening mechanism and the rear tightening mechanism.

[0010] Furthermore, the lifting assembly includes a lifting slider, a drive gear, a drive motor, and a lifting cylinder; the mounting base has a vertically oriented lifting groove, in which the lifting slider is slidably assembled, and a clamping block is connected to the lower end of the lifting slider; the drive gear is rotatably mounted on the mounting base via a transmission shaft, and a rack is provided on the outer surface of the lifting slider along the vertical direction, with the drive gear meshing with the rack; the drive motor is mounted on the mounting base, and its output end is connected to one end of the transmission shaft; the lower end of the lifting cylinder is connected to the mounting base, and the upper end of the lifting cylinder is connected to the lifting slider.

[0011] Furthermore, the drive motor is a servo motor.

[0012] Furthermore, the top of the installation space is provided with support frames on the left and right sides of the corresponding front and rear tightening devices, and the left and right sides of the mounting bases of the front and rear tightening mechanisms are horizontally slidably connected to the support frames.

[0013] Furthermore, the driving mechanism is a telescopic driving mechanism connected between the front tensioning mechanism and the rear tensioning mechanism.

[0014] Furthermore, the telescopic drive mechanism includes a telescopic drive cylinder and a horizontal slide block; a horizontal slide rail is provided on any one of the support frames along the front-rear direction, and a horizontal slide block is slidably provided on the horizontal slide rail at the positions corresponding to the front tensioning mechanism and the rear tensioning mechanism, and the mounting bases of the front tensioning mechanism and the rear tensioning mechanism are both connected to the horizontal slide block; the telescopic drive cylinder is connected between the two horizontal slide blocks.

[0015] Furthermore, the two support frames are provided with horizontal grooves along the horizontal direction on opposite sides, and the left and right sides of the mounting base have extensions that are slidably assembled with the horizontal grooves.

[0016] Furthermore, the left and right pressing edge device includes a left pressing edge assembly and a right pressing edge assembly, and a shoe placement channel is formed between the left pressing edge assembly and the right pressing edge assembly;

[0017] Both the left and right pressing edge assemblies include a cylinder base, a side pressing cylinder, a guide rod, a rubber seat, and a side pressing rubber block. The cylinder base is located at the bottom of the installation space, and the side pressing cylinder is mounted on the cylinder base. The side pressing cylinder has several piston rods distributed along the front-back direction. Each piston rod has a guide rod movably mounted above it. Each piston rod and guide rod has a rubber seat connected to its movable end.

[0020] 1. The front and rear tightening devices are positioned above the left and right pressing devices, and both the front and rear tightening mechanisms are equipped with lifting components. The lifting components are designed with two different drive methods. After the shoe to be pressed is in place or after the pressing operation is completed, the lifting cylinder can drive the tightening block to quickly descend to the lowest point or rise to the highest point. This improves efficiency and allows the tightening block to rise to the highest point during shoe handling, ensuring that the front and rear ends of the left and right pressing devices are not obstructed. This facilitates automatic shoe handling using robotic arms, promoting automated production. Before the drive mechanism brings the tightening blocks of the front and rear tightening mechanisms closer together to tighten the shoe, the drive motor, drive gear, and rack work together to accurately raise the tightening blocks to the required height. This ensures that the two tightening blocks do not touch the underlying structure during subsequent movements, extending the service life of the tightening blocks.

[0021] 2. Multiple sets of left and right pressing devices, front and rear tightening devices and pressing rod devices can be integrated within the installation space of the machine frame. This allows multiple shoes to be pressed on one pressing machine at the same time, which helps to improve production efficiency and reduce space occupation. [Attached Image Description]

Detailed Implementation Methods

[0037] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing these embodiments and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0039] Please see Figures 1 to 7 As shown, this utility model discloses an improved bottom pressing machine 100, which includes:

[0040] The frame 1 has an installation space 11 formed in the middle, which is used to install various devices required for pressing the bottom.

[0041] Left and right pressing devices 2: At least one left and right pressing device 2 is provided at the bottom of the installation space 11. The left and right pressing device 2 is used to press the shoe from the left and right sides. In specific implementation of this utility model, 1 to 3 left and right pressing devices 2 can be provided at the bottom of the installation space 11 according to actual use needs.

[0042] The installation space 11 has a front and rear tightening device 3 at the top, corresponding to the position of each left and right pressing device 2, so that the front and rear tightening device 3 can cooperate with the left and right pressing devices 2 to form a receiving cavity. The front and rear tightening device 3 includes a front tightening mechanism 31, a rear tightening mechanism 32, and a driving mechanism 33 that drives the front tightening mechanism 31 and the rear tightening mechanism 32 to move closer or further apart. During operation, when it is necessary to press the sole of the shoe, the driving mechanism 33 drives the front tightening mechanism 31 and the rear tightening mechanism 32 to move closer to each other to tighten the shoe from both the front and rear ends. After pressing the sole is completed, the driving mechanism 33 drives the shoe to move closer to each other. The front tightening mechanism 31 and the rear tightening mechanism 32 are moved away from each other to loosen the shoe; both the front tightening mechanism 31 and the rear tightening mechanism 32 include a mounting base 341 that can slide back and forth on the frame 1, a lifting component 342 on the mounting base 341, and a tightening block 343 at the lower end of the lifting component 342. During operation, the tightening block 343 can be driven to move up and down by the lifting component 342. The tightening block 343 is made of elastic material, such as rubber block, to ensure that the outer surface of the shoe will not be damaged when tightening. The tightening block 343 has a C-shaped structure that is adapted to the front and rear ends of the shoe.

[0043] The pressure bar device 4 is provided at the top of the installation space 11 at the position corresponding to each left and right pressure edge device 2, and the pressure bar device 4 is located between the front tightening mechanism 31 and the rear tightening mechanism 32. The pressure bar device 4 is used to press the shoe down from the top.

[0044] Please refer to the following embodiments of this utility model. Figure 5 and Figure 6As shown, the lifting assembly 342 includes a lifting slider 3421, a drive gear 3422, a drive motor 3423, and a lifting cylinder 3424. The mounting base 341 has a vertically oriented lifting groove 3411. The lifting slider 3421 is slidably mounted within the lifting groove 3411. A clamping block 343 is connected to the lower end of the lifting slider 3421, allowing the lifting slider 3421 to drive the clamping block 343 to move up and down. The drive gear 3422 is rotatably mounted on the mounting base 341 via a transmission shaft 3425, enabling the drive gear 3422 to rotate. A rack 342a is provided on the outer surface of 421 along the vertical direction. A drive gear 3422 meshes with the rack 342a to drive the lifting slider 3421 to move up and down. A drive motor 3423 is mounted on the mounting base 341, and the output end of the drive motor 3423 is connected to one end of the transmission shaft 3425. The lower end of the lifting cylinder 3424 is connected to the mounting base 341, and the upper end of the lifting cylinder 3424 is connected to the lifting slider 3421 to drive the lifting slider 3421 to move up and down quickly.

[0045] In the specific operation of the lifting assembly 342 of this utility model, after the shoe to be pressed is in place, the lifting cylinder 3424 provides power to drive the clamping block 343 to quickly descend to the lowest position. During this process, the drive motor 3423 does not work. Before the clamping blocks 343 of the front clamping mechanism 31 and the rear clamping mechanism 32 are driven to move closer together to tighten the shoe through the drive mechanism 33, the drive motor 3423 provides power to drive the drive gear 3422 to rotate. The drive gear 3422 drives the lifting slider 3421 and the clamping block 343 to rise together a short distance (e.g., 3mm), thereby ensuring that the two clamping blocks 343 will not touch the structure below in subsequent actions. During this process, the lifting cylinder 3424 does not work. After the shoe pressing operation is completed, the lifting cylinder 3424 provides power to drive the clamping block 343 to quickly rise to the highest position. During this process, the drive motor 3423 does not work. In the specific implementation of this utility model, when it is necessary to raise the tightening block 343 a short distance, the precision requirement is relatively high. Therefore, the drive motor 3423, drive gear 3422 and rack 342a are used in combination to achieve this. However, when the shoes to be pressed are in place and the shoe pressing operation is completed, the tightening block 343 is required to rise and fall quickly, and the precision requirement is relatively low. Therefore, the lifting cylinder 3424 is used to achieve this.

[0046] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0047] 1. The front and rear tightening devices 3 are set above the left and right pressing devices 2, and both the front tightening mechanism 31 and the rear tightening mechanism 32 are equipped with lifting components 342. At the same time, the lifting components 342 are designed to have two different driving methods. When the shoes to be pressed are in place and after the shoe pressing operation is completed, the lifting cylinder 3424 can be used to drive the tightening block 343 to quickly descend to the lowest point or rise to the highest point. This not only helps to improve efficiency, but also drives the tightening block 343 to rise to the highest point when picking up and putting down shoes, so that the front and rear ends of the left and right pressing devices 2 are not blocked. This makes it convenient to automatically pick up and put down shoes with the help of robotic arms, which is conducive to realizing automated production. Before the drive mechanism 33 drives the tightening blocks 343 of the front tightening mechanism 31 and the rear tightening mechanism 32 to come closer to each other to tighten the shoes, the drive motor 3423, drive gear 3422 and rack 342a can work together to drive the tightening blocks 343 to rise accurately to the required height, thereby ensuring that the two tightening blocks 343 will not touch the structure below in subsequent actions, which helps to improve the service life of the tightening blocks 343.

[0048] 2. Multiple sets of left and right pressing devices 2, front and rear tightening devices 3 and pressing rod devices 4 can be integrated within the installation space 11 of the frame 1. This allows multiple shoes to be pressed simultaneously on one pressing machine 100, which helps improve production efficiency and reduces space occupation.

[0049] In one specific embodiment of this utility model, in order to improve control accuracy, the drive motor 3424 is a servo motor.

[0050] In some embodiments of this utility model, the top of the installation space 11 is provided with support frames 12 on the left and right sides of the corresponding front and rear tightening devices 3. The left and right sides of the mounting base 341 of the front tightening mechanism 31 and the rear tightening mechanism 32 are horizontally slidably connected to the support frames 12, so that the front tightening mechanism 31 and the rear tightening mechanism 32 can move horizontally back and forth relative to the support frames 12.

[0051] In some embodiments of this utility model, the driving mechanism 33 is a telescopic driving mechanism connected between the front tightening mechanism 31 and the rear tightening mechanism 32, so that the driving mechanism 33 can drive the front tightening mechanism 31 and the rear tightening mechanism 32 to move synchronously.

[0052] As one specific embodiment of this utility model, please refer to the following: Figure 3 and Figure 4As shown, the telescopic drive mechanism includes a telescopic drive cylinder 331 and a horizontal slide block 332. A horizontal slide rail 121 is provided on each support frame 12 along the front-to-back direction. A horizontal slide block 332 is slidably provided on the horizontal slide rail 121 at positions corresponding to the front tensioning mechanism 31 and the rear tensioning mechanism 32. The mounting bases 341 of the front tensioning mechanism 31 and the rear tensioning mechanism 32 are connected to the horizontal slide block 332, so that when the horizontal slide block 332 slides along the horizontal slide rail 121, it can drive the front tensioning mechanism 31 and the rear tensioning mechanism 32 to move together. The telescopic drive cylinder 331 is connected between the two horizontal slide blocks 332. During operation, the telescopic drive cylinder 331 can move the two horizontal slide blocks 332 closer to each other or further apart by telescopic movement.

[0053] In some embodiments of this utility model, the two support frames 12 are provided with horizontal sliding grooves 122 along the horizontal direction on opposite sides, and the left and right sides of the mounting body 341 are provided with extensions 3412 that are slidably assembled with the horizontal sliding grooves 122. By adopting the above structural design, the mounting body 341 can slide along the horizontal sliding grooves 122, and the support requirements for the mounting body 341 can be met.

[0054] Please refer to the following embodiments of this utility model. Figure 7 As shown, the left and right pressing device 2 includes a left pressing component 21 and a right pressing component 22. A shoe placement channel 23 is formed between the left pressing component 21 and the right pressing component 22. When in use, the shoes to be pressed need to be placed in the shoe placement channel 23. The shoes to be pressed are pre-installed with shoe lasts.

[0055] Both the left pressing edge assembly 21 and the right pressing edge assembly 22 include a cylinder base 241, a side pressing cylinder 242, a guide rod 243, a rubber seat 244, and a side pressing rubber block 245. The cylinder base 241 is located at the bottom of the installation space 11, specifically, the cylinder base 241 is located on the left and right sides of the shoe placement channel 23, and the side pressing cylinder 242 is mounted on the cylinder base 241. The side pressing cylinder 242 has several piston rods 246 distributed along the front-back direction. Each piston rod 246 has a guide rod 243 movably mounted above it. The movable ends of each piston rod 246 and guide rod 243 are connected to a rubber seat 244. Each rubber seat 244 has a side pressing rubber block 245 on the side facing the shoe placement channel 23, and the side pressing rubber blocks 245 are arranged adjacent to each other. When it is necessary to press the shoe from the side, the side pressure cylinder 242 drives the piston rods 246 to move the side pressure rubber blocks 245 forward, so that the side pressure rubber blocks 245 press the shoe from the side. After the pressing operation is completed, the side pressure cylinder 242 drives the piston rods 246 to move the side pressure rubber blocks 245 back to their original position, so that the side pressure rubber blocks 245 are no longer in contact with the shoe.

[0056] In some embodiments of this utility model, the pressure rod device 4 includes a front pressure rod assembly 41 and a rear pressure rod assembly 42. The upper ends of both the front pressure rod assembly 41 and the rear pressure rod assembly 42 are connected to the top of the mounting space 11. During operation, one of the front pressure rod assembly 41 and the rear pressure rod assembly 42 is used to press down the top of the shoe toe, and the other is used to press down the top of the shoe last at the shoe opening. It should be noted that the front pressure rod assembly 41 and the rear pressure rod assembly 42 are existing components, and their specific structures and working principles are well known to those skilled in the art. Therefore, a detailed description of the front pressure rod assembly 41 and the rear pressure rod assembly 42 will not be provided here.

[0057] In a specific implementation of this invention, to further facilitate the taking and placing of shoes, the left and right pressing devices 2 can be set on top of a lifting device 5. The lifting device 5 can specifically be a lifting cylinder. During operation, the lifting device 5 can drive the left and right pressing devices 2 to move up and down, so that when taking and placing shoes, the left and right pressing devices 2 can maintain a sufficiently large distance from the front and rear tightening devices 3 and the pressing rod device 4, thereby making it easier to take and place shoes.

[0058] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
