Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of footwear production, and specifically to a flat sole pressing machine with an improved structure for footwear production. BACKGROUND

[0002] Shoes have a long history of development. The most primitive shoes made of animal skins appeared in the Yangshao culture period about 5,000 years ago. Shoes are a tool to protect feet from injury. The earliest people invented fur shoes to overcome special situations and prevent feet from being uncomfortable or injured. Shoes have developed to their current form, and various styles and functions of shoes can be seen everywhere. Currently, after the completion of the manufacture of soles and uppers, the soles and uppers are bonded by glue.

[0003] For example, a full-automatic sole pressing device for shoes with the authorization announcement number CN210299764U includes a workbench, two wheels are fixedly installed on the bottom left and right sides of the workbench, support plates are fixedly installed on the top left and right sides of the workbench, and the top of each of the two support plates is fixedly connected with a connecting plate. The above document still has deficiencies. In use, an electric screw rod is arranged. When the electric screw rod works, the screw rod nut moves forward and backward, thereby adjusting the distance between the fourth hydraulic push rod and the third hydraulic push rod, thereby achieving the purpose of adapting to different sizes of shoes. The second hydraulic push rod pushes the movable plate to move up and down in the sleeve, so that shoes of different heights placed on the movable plate can achieve good bonding effect. However, in the sole pressing device in the above document, the hydraulic push rod is used to extrude the sole to bond the sole and the upper together. The surface area of the output end of the hydraulic push rod is limited, and the contact area with the sole is also limited. The bonding effect outside the extrusion position will be relatively poor, thereby reducing the bonding effect between the sole and the upper. At the same time, after the device in the above document bonds the sole and the upper together to form a shoe, the bonded shoe is taken off and placed into the upper and the sole that have not been bonded. This process needs to be waited for. When a batch of shoes needs to be produced and processed, the processing efficiency is low. SUMMARY

[0004] The utility model aims at solving the problem of reducing the bonding effect between the sole and the upper and proposes a flat sole pressing machine with an improved structure for footwear production.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] The utility model relates to a flat type sole pressing machine for shoe production with improved structure, which comprises a base frame and a workbench, the workbench is fixedly connected above the base frame, a second support is fixedly connected above the workbench, a rotating mechanism is arranged in the base frame, a cylinder and a first sleeve are fixedly connected below the second support, a first sliding rod is slidably connected in the first sleeve, and a flat pressing mechanism is arranged at the output end of the cylinder.

[0007] Preferably, the flat pressing mechanism comprises a first support fixedly connected with the output end of the cylinder, the first support is fixedly connected with the lower end of the first sliding rod, two first electric push rods are fixedly connected to the outer wall of the first support, a connecting block is fixedly connected to the output end of the first electric push rod, the connecting block is fixedly connected to the upper surface of the first pressing plate, a support rod is fixedly connected to the outer wall of the first pressing plate, the support rod is slidably connected with a second pressing plate, and the second pressing plate is fixedly connected below the first support.

[0008] Preferably, the rotating mechanism comprises a motor fixedly connected in the base frame, a first disc is fixedly connected to the output shaft of the motor, the first disc is rotatably connected with the base frame through a bearing, a protrusion and a pin rod are fixedly connected to the upper surface of the first disc, the outer wall of the protrusion is slidably connected with a groove, the outer wall of the pin rod is slidably connected with a sliding groove, the groove and the sliding groove are arranged in a grooved wheel, a rotating rod is fixedly connected above the grooved wheel, and the rotating rod is rotatably connected with the workbench through a bearing.

[0009] Preferably, a second disc is fixedly connected to the upper end of the rotating rod, a vertical rod is fixedly connected to the lower surface of the second disc, and the lower end of the vertical rod is slidably connected with an annular groove arranged in the workbench.

[0010] Preferably, a second electric push rod is fixedly connected to the upper surface of the second disc, and a support plate is fixedly connected to the output end of the second electric push rod.

[0011] Preferably, the outer wall of the support plate is slidably connected with the second disc, and a second sleeve is fixedly connected to the outer wall of the support plate.

[0012] Preferably, a second sliding rod is slidably connected in the second sleeve, and a clamping block is fixedly connected to the end of the second sliding rod.

[0013] Preferably, a spring is arranged in the second sleeve, and the two ends of the spring are fixedly connected with the second sleeve and the second sliding rod respectively.

[0014] This utility model proposes a flat sole pressing machine with an improved structure for footwear production. The beneficial effects are as follows: Through the cooperation of a first support, a first electric push rod, a connecting block, a first pressure plate, a support rod, and a second pressure plate, a cylinder drives the first support to move downwards. The first support drives the second pressure plate to move downwards, and the two first pressure plates move downwards along with the second pressure plate. The second pressure plate and the two first pressure plates contact the upper surface of the sole and press it, bonding the sole to the upper. The cylinder then drives the first and second pressure plates upwards, reversing the activation of the first electric push rod. The outer walls of the first and second pressure plates adhere to each other. The cylinder then drives the first and second pressure plates downwards to press the sole. The position of the first pressure plate changes, pressing areas that were not previously pressed, thus ensuring complete contact and pressing with the entire upper surface of the sole, leaving no unpressed areas, thereby improving the adhesion between the sole and the upper.

[0015] Through the cooperation of the motor, the first disc, the protrusion, the pin, the groove, the slide, the grooved wheel, and the rotating rod, the motor drives the first disc to rotate, the first disc drives the protrusion and the pin to move, the pin inserts into the inside of the slide and drives the grooved wheel to rotate through the slide. The slide is equipped with four grooved wheels that rotate exactly 90 degrees. At this time, the outer wall of the protrusion is inside the groove to prevent the grooved wheel from rotating under the action of inertia. When the grooved wheel rotates, it drives the rotating rod to rotate, and the rotating rod drives the second disc to rotate. The unprocessed shoe upper and sole are placed under the first pressure plate and the second pressure plate. The shoe formed by the shoe upper and sole that are glued together is separated from the first pressure plate and the second pressure plate. The motor is turned off and the cylinder is started to perform flat pressing of the sole. The shoe formed after glued is removed, the un-glued shoe upper is clamped and glued and the sole is placed. The glued shoe is removed and the un-glued shoe upper and sole are put in. This process does not require waiting and has high processing efficiency when batch processing of shoes is required.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] See attached document Figures 1-8 In this embodiment, a flat sole pressing machine for footwear production with an improved structure includes a base frame 1 and a worktable 2. The worktable 2 is fixed above the base frame 1, and a second support 5 is fixed above the worktable 2. A rotating mechanism 4 is provided inside the base frame 1. The rotating mechanism 4 rotates the second disc 10, so that the finished shoe is below the second pressing plate 306, and the unprocessed upper and sole are below the second pressing plate 306. The sole and upper are bonded together to form a shoe. A cylinder 6 and a first sleeve 7 are fixed below the second support 5. There are two first sleeves 7. A first sliding rod 8 is slidably connected inside the first sleeve 7. The first sliding rod 8 slides inside the first sleeve 7. The first sliding rod 8 and the first sleeve 7 guide the movement of the first support 301. A flat pressing mechanism 3 is provided at the output end of the cylinder 6. The flat pressing mechanism 3 squeezes and bonds the sole and upper.

[0027] The flattening mechanism 3 includes a first support 301, a first electric push rod 302, a connecting block 303, a first pressure plate 304, a support rod 305, and a second pressure plate 306. The first support 301 is fixedly connected to the output end of the cylinder 6. The liquid pump 6 drives the first support 301 to move. The first support 301 is fixedly connected to the lower end of the first slide rod 8. Two first electric push rods 302 are fixedly connected to the outer wall of the first support 301. The two first electric push rods 302 are symmetrically arranged. The output end of the first electric push rod 302 is fixedly connected to the connecting block 303. The first electric push rod 302 drives the connecting block 306. Block 303 moves, and connecting block 303 is fixed to the upper surface of the first pressure plate 304. Connecting block 303 drives the first pressure plate 304 to move. A support rod 305 is fixed to the outer wall of the first pressure plate 304. The first pressure plate 304 drives the support rod 305 to move. The outer wall of the support rod 305 is slidably connected to the second pressure plate 306. The support rod 305 slides inside the second pressure plate 306. The support rod 305 plays a supporting and guiding role in the movement of the first pressure plate 304. The second pressure plate 306 is fixed to the bottom of the first bracket 301. The first bracket 301 drives the second pressure plate 306 to move.

[0028] Cylinder 6 drives the first support 301 to move downwards, which in turn drives the second pressure plate 306 to move downwards. The two first pressure plates 304 move downwards along with the second pressure plate 306. The second pressure plate 306 and the two first pressure plates 304 contact the upper surface of the sole and squeeze the sole, bonding it to the upper. Cylinder 6 then drives the first pressure plate 304 and the second pressure plate 306 to move upwards, reversing the movement of the first electric push rod 302. The first pressure plate 304 then adheres to the outer wall of the second pressure plate 306. Cylinder 6 drives the first pressure plate 304 and the second pressure plate 306 to move downwards, squeezing the sole. The position of the first pressure plate 304 changes, squeezing areas that were not squeezed previously, thus ensuring full contact and squeezing of the upper surface of the sole. This eliminates any unsqueezed areas, improving the adhesion between the sole and the upper.

[0029] The rotating mechanism 4 includes a motor 401, a first disc 402, a protrusion 403, a pin 404, a groove 405, a slide 406, a grooved wheel 407, and a rotating rod 408. The motor 401 is fixedly connected inside the base frame 1. The output shaft of the motor 401 is fixedly connected to the first disc 402. The motor 401 drives the first disc 402 to rotate. The first disc 402 is rotatably connected to the base frame 1 through bearings. The protrusion 403 and the pin 404 are fixedly connected to the upper surface of the first disc 402. The first disc 402 drives the protrusion 403 and the pin 404 to rotate. The outer wall of the protrusion 403 is slidably connected to the groove 405. When the protrusion 403 is inside the groove 405, it prevents the grooved wheel 407 from rotating under inertia. The outer wall of the pin 404 is slidably connected to the slide groove 406. The pin 404 drives the grooved wheel 407 to rotate by cooperating with the slide groove 406. The groove 405 and the slide groove 406 are both set inside the grooved wheel 407. A rotating rod 408 is fixedly connected above the grooved wheel 407. The grooved wheel 407 and the rotating rod 408 rotate together. The outer wall of the rotating rod 408 is rotatably connected to the worktable 2 through a bearing.

[0030] Motor 401 drives the first disc 402 to rotate, which in turn drives the protrusion 403 and pin 404 to move. Pin 404 inserts into the groove 406 and drives the grooved wheel 407 to rotate via the groove 406. The groove 406 has four grooved wheels 407 that rotate exactly 90 degrees. At this time, the outer wall of the protrusion 403 is inside the groove 405, preventing the grooved wheels 407 from rotating due to inertia. As the grooved wheels 407 rotate, they drive the rotating rod 408 to rotate, which in turn drives the second disc 10 to rotate, thus removing the unprocessed material. The upper and sole are located below the first pressure plate 304 and the second pressure plate 306. The shoe formed by the glued upper and sole is separated from the first pressure plate 304 and the second pressure plate 306. The motor 401 is turned off, and the cylinder 6 is started to perform flat pressing. The glued shoe is removed, the un-glued upper is clamped, glue is applied, and the sole is placed. The glued shoe is removed and the un-glued upper and sole are put in. This process does not require waiting and has high processing efficiency when batch production of shoes is required.

[0031] A second disk 10 is fixedly connected to the upper end of a rotating rod 408. The rotating rod 408 drives the second disk 10 to rotate. Four vertical rods 9 are fixedly connected to the lower surface of the second disk 10. The lower end of each vertical rod 9 is slidably connected to an annular groove within the worktable 2. The vertical rods 9 slide within the annular groove within the worktable 2, providing support and guidance for the movement of the second disk 10. Eight second electric push rods 11 are fixedly connected to the upper surface of the second disk 10, arranged in pairs opposite each other. A support plate 12 is fixedly connected to the output end of each second electric push rod 11. The second electric push rods 11 drive the support plate 12 to move. The outer wall of the second sleeve is slidably connected to the second disc 10. The support plate 12 slides on the upper surface of the second disc 10. The outer wall of the support plate 12 is fixedly connected to the second sleeve 13. The support plate 12 drives the second sleeve 13 to move. The second slide rod 14 is slidably connected inside the second sleeve 13. The second slide rod 14 slides inside the second sleeve head 13. The end of the second slide rod 14 is fixedly connected to the clamping block 16. The second slide rod 14 drives the clamping block 16 to move. The second sleeve 13 is provided with a spring 15. The model of the spring 15 is selected according to the actual use requirements to meet the working needs. The two ends of the spring 15 are fixedly connected to the second sleeve 13 and the second slide rod 14 respectively.

[0032] Working principle:

[0033] When using a flat sole press machine with an improved structure for footwear production to process shoes, the upper is placed between two corresponding support plates 12. The second electric push rods 11 on both sides are activated. The second electric push rods 11 drive the support plates 12 to slide. The support plates 12 drive the second sleeve 13 to move, which in turn drives the clamping block 16 to move. The outer wall of the clamping block 16 contacts the upper. The clamping block 16 moves together with the second sliding rod 14. The second sliding rod 14 can slide into the second sleeve 13 to compress the spring 15, so that the clamping block 16 can adapt to different shapes of the upper while ensuring a firm compression. Glue is applied to the upper surface of the upper, and then the corresponding sole is placed in. The upper is clamped between all four sets of support plates 12. Finally, glue is applied to the upper and the sole is placed.

[0034] Flat bottom pressing stage:

[0035] The first electric push rod 302 is activated, driving the connecting block 303 to move. The connecting block 303 then moves the first pressure plate 304, which in turn moves the support rod 305. The support rod 305 slides inside the second pressure plate 306, supporting and guiding the movement of the first pressure plate 304, ensuring that the distance between the two ends of the two first pressure plates 304 is greater than the length of the sole. The first electric push rod 302 is then deactivated, activating the cylinder 6. The cylinder 6 drives the first bracket 301 downward, which in turn moves the second pressure plate 306 downward. The two first pressure plates 304 move downward along with the second pressure plate 306, contacting the upper surface of the sole and pressing it to bond the sole to the upper. Cylinder 6 drives the first pressure plate 304 and the second pressure plate 306 to move upward, and reverses the start of the first electric push rod 302. The outer walls of the first pressure plate 304 and the second pressure plate 306 are in contact. Cylinder 6 drives the first pressure plate 304 and the second pressure plate 306 to move downward to squeeze the sole. The position of the first pressure plate 304 changes, squeezing the area that was not squeezed in the previous operation, and then making full contact with the upper surface of the sole. There are no unsqueezed areas, thereby improving the adhesion between the sole and the upper. The lower surfaces of the first pressure plate 304 and the second pressure plate 306 are both horizontally set, realizing a flat sole pressing machine for footwear production. The position of the first pressure plate 304 can be adjusted to make the squeezing of the sole more comprehensive, realizing a flat sole pressing machine for footwear production with an improved structure.

[0036] Rotation phase:

[0037] After the sole and upper are flat-pressed and bonded together to form a shoe, cylinder 6 drives the first pressure plate 304 and the second pressure plate 306 to move upward and separate from the shoe. Motor 401 is then activated, driving the first disc 402 to rotate. The first disc 402 drives the protrusion 403 and pin 404 to move. Pin 404 inserts into the groove 406 and drives the grooved wheel 407 to rotate through the groove 406. The groove 406 has four grooved wheels 407 that rotate exactly ninety degrees. At this time, the outer wall of the protrusion 403 is inside the groove 405, preventing the grooved wheel 407 from rotating due to inertia. As the grooved wheel 407 rotates, it drives the rotating rod 408. The rotating rod 408 drives the second disc 10 to rotate. The second disc 10 rotates 90 degrees, placing the unprocessed upper and sole under the first pressure plate 304 and the second pressure plate 306. This separates the shoe formed by the glued upper and sole from the first pressure plate 304 and the second pressure plate 306. The motor 401 is turned off, and the cylinder 6 is started to perform flat pressing. The glued shoe is removed, the un-glued upper is clamped, glue is applied, and the sole is placed. The glued shoe is then removed, and the un-glued upper and sole are placed in. This process does not require waiting and has high processing efficiency when batch production of shoes is required.

[0038] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
