Description

Technical Field

[0001] This application relates to the field of rubber boot processing technology, specifically to the lining socks, steel liner, and anti-impact foot mounting and positioning mechanism for rubber boot molding. Background Technology

[0002] Rubber boots are shoes with a slightly cylindrical upper that extends above the ankle. They typically consist of a boot body, a sole, and a lining. In certain specialized work environments, such as mining operations, additional protective measures are added to standard rubber boots. For instance, to prevent heavy impacts to the toes and instep in mining conditions, steel inserts and impact-resistant insteps can be built into the corresponding areas of the boots. The steel inserts primarily protect the toes from impacts, while the impact-resistant insteps protect the instep from impacts.

[0003] Traditional rubber boot production relies on labor-intensive production lines. On these simple lines, workers manually attach and position various components—including rubber sheets, linings, steel sleeves, anti-slip insoles, and soles—on a shoe last to form a boot. The boot is then vulcanized in a vulcanizing tank to create the final product. However, this traditional production method requires significant manpower and resources, resulting in low efficiency. Furthermore, varying worker skill levels lead to numerous product defects and poor consistency.

[0004] Therefore, how to improve the traditional rubber boot production line to overcome the above-mentioned shortcomings is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this application is to provide a positioning mechanism for installing and positioning the liner, steel ladle, and anti-impact footplate for molding rubber boots, in order to solve the problems of low production efficiency, numerous product defects, and poor product consistency caused by the need for manual installation of the liner, steel ladle, and anti-impact footplate in the prior art.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a sock, steel ladle, and anti-impact foot mounting and positioning mechanism for rubber boot molding, including a stand, a sock mounting assembly, a steel ladle mounting assembly, and an anti-impact foot mounting assembly; the sock mounting assembly includes a sock tube, which is vertically arranged on the stand and is used to pass through the last body from top to bottom, and the upper end of the sock tube is used to tension and fix the cuff of the sock; the steel ladle mounting assembly includes a sliding frame and a positioning block; the sliding frame is along the direction of the foot, near or away from the last body.

[0007] Preferably, the stocking installation assembly further includes a frame, which is slidably connected to the upright; the number of stocking tubes is two, the two stocking tubes are symmetrically arranged, and the two stocking tubes are slidably connected to the frame facing each other or back to back.

[0008] Preferably, there are two positioning blocks and two flipping blocks, and the two positioning blocks and the two flipping blocks are arranged symmetrically about the sock tube.

[0009] Preferably, the sliding direction of the frame is the same as the sliding direction of the sliding bracket.

[0010] Preferably, the ladle mounting assembly further includes a first locking member, which is disposed on the positioning block and used to lock the ladle in the first positioning groove.

[0011] Preferably, the first locking element and / or the second locking element are electromagnets.

[0012] Preferably, the anti-smashing foot mounting assembly further includes a positioning member, which is disposed on the flipping member and is used to position the flipping angle of the flipping member by abutting against the sliding frame.

[0013] Preferably, the flipping component includes a flipping arm, a sleeve, a first spring, and an abutment. One end of the flipping arm is rotatably connected to the sliding frame, and the other end of the flipping arm is slidably connected inside the sleeve. The first spring is disposed inside the sleeve and is used to compress and reset the flipping arm and the sleeve. The abutment is disposed on the upright and is used to compress the sleeve and the flipping arm through abutment. The flipping block is installed on the side of the sleeve.

[0014] Preferably, the sleeve has a through hole extending through it axially; the flipping component also includes an adjusting rod, one end of which passes through the through hole and is then threaded to the flipping arm, and the other end of the adjusting rod has a limiting part with a size larger than the through hole.

[0015] Preferably, the anti-smashing foot mounting assembly further includes a flipping drive component, which includes a drive motor, a worm gear, and a worm wheel; the drive motor is mounted on the sliding frame, and both the worm gear and the worm wheel are rotatably mounted on the sliding frame; the worm gear is connected to the output shaft of the drive motor, and the worm gear meshes with the worm wheel; the flipping arm is radially connected to the worm wheel.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: (1) Since the pantyhose installation component includes a pantyhose tube, which is vertically set on the stand, the pantyhose tube is used for the last body to pass through up and down, and the upper end of the pantyhose tube is used to tension and fix the pantyhose cuff; therefore, it is only necessary to manually attach the pantyhose cuff to the pantyhose tube, and then the robot will first move the last body to the top of the pantyhose tube, and then drive the last body to move downward, so that the pantyhose on the pantyhose tube can be put on the last body, thereby completing the installation and positioning of the pantyhose.

[0017] (2) The ladle installation assembly includes a sliding frame and a positioning block; the sliding frame is slidably connected to the upright frame along the direction of the foot near or away from the last body, and the sliding frame is located below the sock tube; the positioning block is set on the sliding frame, and the positioning block is provided with a first positioning groove for adapting to the ladle; the anti-smashing foot installation assembly includes a flipping part, a flipping block and a second locking part, the flipping part is rotatably set on the sliding frame; the flipping block is set on the flipping part, and the flipping block is provided with a second positioning groove for adapting to the anti-smashing foot; the second locking part is set on the flipping block and is used to lock the anti-smashing foot in the second positioning groove. Therefore, it is only necessary to drive the sliding frame to slide to the outside of the stocking tube. At this point, the steel ladle can be placed into the first positioning slot manually or by a robotic arm, which temporarily fixes the steel ladle. Additionally, the flipping component can be controlled to rotate, so that the second positioning slot faces upwards, facilitating the placement of the anti-smashing foot in the second positioning slot manually or by a robotic arm. The second locking component locks the anti-smashing foot in place with the second positioning slot. Then, the flipping component is driven to rotate, so that the second positioning slot faces downwards, and the second locking component prevents the anti-smashing foot from falling off. After the last body passes downwards through the stocking tube and aligns with the anti-smashing foot and steel ladle, the sliding frame is driven to move towards the toe of the last body, sequentially assembling the anti-smashing foot and steel ladle onto the last body. The last body can use a positioning part to temporarily position and fix the anti-smashing foot and steel ladle, thus achieving the installation positioning of the anti-smashing foot and steel ladle.

[0018] (3) As can be seen from the above, the installation and positioning mechanism for the liner, steel liner and anti-smashing foot of the rubber boots made in this application can realize the installation and positioning of the liner, steel liner and anti-smashing foot onto the last body. Compared with the traditional manual operation, this application has the advantages of high production efficiency, fewer defects and high product consistency. Attached Figure Description

[0031] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] In the description of this application, it should be noted that directional terms such as "center," "lateral," "longitudinal," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing this application and 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. They should not be construed as limiting the specific scope of protection of this application. The terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "comprising" and "having," and any variations thereof, in the specification and claims of this application, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0033] Reference Figures 1 to 11 One embodiment of this application provides a mounting and positioning mechanism for a rubber boot molding liner, a steel ladle 100, and an anti-impact foot instep 200, including a stand 11, a liner mounting assembly 1, a steel ladle mounting assembly 2, and an anti-impact foot instep mounting assembly 3; the liner mounting assembly 1 includes a sock tube 12, which is vertically mounted on the stand 11 and passes through the last body 4 vertically, with the upper end of the sock tube 12 used to tension and fix the cuff of the liner; the steel ladle mounting assembly 2 includes a sliding frame 22 and a positioning block 22; the sliding frame 22 is slidably connected to the stand along the direction close to or away from the toe 41 of the last body 4. The frame 11 and the sliding frame 22 are located below the sock tube 12; the positioning block 22 is set on the sliding frame 22, and the positioning block 22 is provided with a first positioning groove 221 for adapting to the steel ladle 100; the anti-smashing foot mounting assembly 3 includes a flipping part 31, a flipping block 32 and a second locking part 33, the flipping part 31 is rotatably set on the sliding frame 22; the flipping block 32 is set on the flipping part 31, and the flipping block 32 is provided with a second positioning groove 321 for adapting to the anti-smashing foot 200; the second locking part 33 is set on the flipping block 32 and is used to lock the anti-smashing foot 200 in the second positioning groove 321.

[0034] Working principle: The process involves manually attaching the cuff of the stocking to the stocking tube 12. Then, a robot grips the last body 4, moves it directly above the stocking tube 12, and drives it downwards to place the stocking onto the last body 4, thus completing the installation and positioning of the stocking. Alternatively, the sliding frame 22 can be slid to the outside of the stocking tube 12, allowing the steel ladle 100 to be placed into the first positioning groove 221 manually or with a robotic arm. The first positioning groove 221 provides temporary fixation for the steel ladle 100. Furthermore, the rotating component 31 can be controlled to rotate, causing the second positioning groove 321 to face upwards (e.g., ...). Figure 5 As shown), the anti-smashing foot surface 200 can be placed into the second positioning groove 321 manually or by a robotic arm, and the anti-smashing foot surface 200 and the second positioning groove 321 can be locked together by the second locking member 33; then the flipping member 31 is driven to rotate, so that the second positioning groove 321 is arranged downwards (as shown). Figure 2 As shown in the diagram, this facilitates subsequent assembly, and the second locking element 33 prevents the anti-smashing foot 200 from falling off. After the last body 4 passes downward through the sock tube 12 and aligns with the anti-smashing foot 200 and the steel liner 100, the sliding frame 22 is driven to move towards the toe 41 of the last body 4, thereby sequentially assembling the anti-smashing foot 200 and the steel liner 100 onto the last body 4. The positioning part 411 on the last body 4 can be used to temporarily position and fix the anti-smashing foot 200 and the steel liner 100, thus realizing the installation and positioning of the anti-smashing foot 200 and the steel liner 100.

[0035] It is understood that the robot and robotic arm are existing technologies, so they will not be described in detail here, nor are they shown in the attached drawings. The sliding mounting method of the sliding frame 22 is also existing technology, so it will not be described in detail here.

[0036] In addition, since the stockings in the prior art are elastic, the stockings can be temporarily fixed simply by manually placing them inside the stocking tube 12, holding the top of the stockings with both hands, and then flipping the top of the stockings over the top of the stocking tube 12.

[0037] It should be understood that during the process of fitting the stocking into the last 4, the friction between the stocking cuff and the stocking tube 12 should be greater than the squeezing force exerted by the last 4 on the inside of the stocking. This is to prevent the stocking from not being able to fit smoothly onto the last 4 when it moves down. There are many ways to ensure that the friction between the stocking cuff and the stocking tube 12 is greater than the squeezing force exerted by the last 4 on the inside of the stocking. For example, the diameter of the stocking tube 12 can be increased. The larger the diameter, the greater the friction between the stocking cuff and the stocking tube 12. Another example is to increase the length of the stocking cuff, that is, the longer the stocking cuff is fitted onto the stocking tube 12, the greater the friction between the stocking cuff and the stocking tube 12. In some cases, the stocking can even be completely rolled up and fitted onto the stocking tube 12.

[0038] Understandably, during the injection molding process of the last body 4 in conjunction with the mold, the lining stocking can be simultaneously fitted onto the stocking tube. After the mold opens and the finished rubber boot is removed, the robot can then use the last body 4 to install the lining stocking, resulting in higher work efficiency. To further improve work efficiency, two sets of last bodies 4 can be used alternately. One set of last bodies 4 is clamped to the boot removal station after molding to remove the boot, while the other set of last bodies 4 has already completed the installation of the lining stocking at the lining stocking installation station. At this point, the robot can directly clamp the last body 4 with the completed lining stocking and put it into the next molding cycle. The last body 4, after removing the boot at the boot removal station, is then transferred to the lining stocking installation station to complete the installation of the lining stocking.

[0039] Reference Figure 1 and Figure 3 In some embodiments of this application, the stocking installation assembly 1 further includes a frame 13, which is slidably connected to the upright 11; the number of stocking tubes 12 is two, the two stocking tubes 12 are symmetrically arranged, and the two stocking tubes 12 are slidably connected to the frame 13 facing each other or back to back. Since the size of the stocking tubes 12 is larger than the size of the last body 4, and in the mold design, the distance between the two last bodies 4 cannot be designed to be very large, and the influence on the mold size also needs to be considered, this results in a relatively small distance between the two stocking tubes 12 when they are fitted with the two last bodies 4. However, when the stocking is manually fitted onto the two stocking tubes 12, the small distance between the two stocking tubes 12 makes it inconvenient for manual adjustment of the stocking between the two stocking tubes 12. To solve this problem, this design is adopted, that is, when the stocking is manually fitted, the frame 13 is controlled to slide away from the robot, and during this process, the two stocking tubes 12 are controlled to slide back to back, thereby increasing the distance between the two stocking tubes 12 (e.g., Figure 3 As shown in the diagram, this facilitates manual placement of the stocking under the stocking tube 12, and also makes it easier for manual adjustment of the stocking between the two stocking tubes 12. Furthermore, the manual placement of the stocking is far from the robot, resulting in higher operational safety.

[0040] It should be understood that the sliding installation method of the frame 13 is existing technology, such as using guide blocks and guide rails to achieve sliding limit, and using a screw drive to drive it. The sliding method between the two stocking tubes 12 is also existing technology. For example, two double-threaded rods 14 are rotatably connected to the frame 13, and the left and right sides of the stocking tubes 12 are respectively threaded to the two double-threaded rods 14. By driving the double-threaded rods 14 to rotate by a motor, the two stocking tubes 12 can be driven to move towards each other or away from each other at the same time.

[0041] Reference Figure 2In some embodiments of this application, there are two positioning blocks 22 and two flipping blocks 32, and the two positioning blocks 22 and the two flipping blocks 32 are arranged symmetrically about the sock tube 12.

[0042] Reference Figure 1 In some embodiments of this application, the sliding direction of the frame 13 is the same as the sliding direction of the sliding frame 22.

[0043] Reference Figure 2 In some embodiments of this application, the ladle mounting assembly 2 further includes a first locking member 23, which is disposed on the positioning block 22 and used to lock the ladle 100 in the first positioning groove 221. The first locking member 23 can lock the ladle 100 in the first positioning groove 221, ensuring that the ladle 100 will not shift its position during the movement of the sliding frame 22; after the assembly between the ladle 100 and the last body 4 is completed, the first locking member 23 can be engaged to lock it. Both the first locking member 23 and the second locking member 33 are preferably electromagnets, which facilitate the locking and unlocking operations of the ladle 100 and the anti-smashing foot 200.

[0044] Reference Figures 4 to 7 In some embodiments of this application, the flipping member 31 includes a flipping arm 311, a sleeve 312, a first spring 313, and an abutment member 314. One end of the flipping arm 311 is rotatably connected to the sliding frame 22, and the other end of the flipping arm 311 is slidably connected to the sleeve 312. The first spring 313 is disposed in the sleeve 312 and is used to compress and reset the flipping arm 311 and the sleeve 312. The abutment member 314 is disposed on the upright frame 11 and is used to compress the sleeve 312 and the flipping arm 311 through the abutment action. The flipping block 32 is installed on the side of the sleeve 312. After the temporary fixing of the steel ladle 100 and the anti-smashing foot surface 200 is completed, the sliding frame 22 is controlled to move towards the robot. During the movement, the flipping arm 311 flips to the left side of the upright frame 11, so that the anti-smashing foot surface 200 in the second positioning groove 321 faces downward. Under the action of the second locking member 33, the downward-facing anti-smashing foot surface 200 will not fall off. When the last body 4 passes downward through the sock tube and the position of the toe 41 is aligned with the position of the steel ladle 100 and the anti-smashing foot surface 200, the sliding frame 22 continues to move towards the robot (i.e., the left end of the upright frame 11). At this time, the anti-smashing foot surface 200 will first pass through the toe 41, and when the sleeve 312 contacts the contact member 314 (the position of the contact member 314 is as follows)... Figure 4(As shown) When the flipping block 32 (second positioning groove 321) and the anti-smashing foot 200 cannot continue to move relative to the last body 4 (i.e., the toe 41), the sliding frame 22 continues to move towards the left end of the upright frame 11, that is, the first spring 313 between the sleeve and the flipping arm 311 will be compressed, so that the steel ladle 100 continues to move to the left relative to the anti-smashing foot 200 (last body 4, toe 41) until the steel ladle 100 is engaged with the engaging groove 202 on the anti-smashing foot 200 (as shown). Figure 10 and Figure 11 (As shown) Inside, at the same time, the ladle 100 will also be engaged with the positioning part 411 (as shown). Figure 9 As shown), the steel ladle 100 is positioned and fixed on the positioning part 411, while the anti-smashing foot 200 is positioned on the steel ladle 100, thus realizing the installation between the steel ladle 100, the anti-smashing foot 200 and the last body 4. In order to prevent relative displacement between the anti-smashing foot 200 and the second positioning groove 321 during the process of the steel ladle 100 being engaged in the engagement groove 202, a retaining edge 3211 is provided at one end of the second positioning groove 321 (e.g., ...). Figure 5 As shown), the thickness of the retaining edge 3211 is the same as the thickness of the anti-smashing foot surface 200. When the steel ladle 100 is inserted into the locking groove 202, the retaining edge 3211 will prevent relative sliding between the anti-smashing foot surface 200 and the second positioning groove 321. The specific structure of the second locking member 33 is preferably an electromagnet, which facilitates locking and unlocking of the anti-smashing foot surface 200. A clearance groove 201 is also provided on the anti-smashing foot surface 200 corresponding to the positioning part 411 to prevent interference with the positioning part 411. In other words, after adopting this solution, the anti-smashing foot surface 200 can be locked onto the steel ladle 100 by using the locking groove 202 on the anti-smashing foot surface 200, and the steel ladle 100 can be locked onto the positioning part 411. This reduces the number of positioning parts 411 on the last body 4. Otherwise, the more positioning parts 411 there are, the more pits will be generated on the inner side of the rubber boot after molding.

[0045] It should be understood that this application does not limit the specific structure of the positioning part 411, for example... Figure 9 As shown, the positioning part 411 is an L-shaped locking post and a cylindrical support structure. The L-shaped locking post limits and supports the steel insulator 100, while the cylindrical support provides support for the steel insulator 100, allowing it to suspend at the front of the toe 41. After injection molding, the rubber fills the gap between the steel insulator 100 and the toe 41, ensuring that the steel insulator 100 is completely encased in the rubber of the boot body and the insole. To prevent the positioning part 411 from affecting the last body 4 during the downward insertion of the liner stocking, the surface of the positioning part 411 needs to be smoothed to remove sharp edges, thus preventing it from scratching the liner stocking during the downward movement of the last body 4.

[0046] Understandably, the length of the stocking tube 12 should be such that the lower end of the last body 4 can completely protrude downwards from the stocking tube 12, thereby achieving assembly with the steel ladle 100 and the anti-smashing foot surface 200, and at this time, the sliding will not touch the upper end of the stocking tube 12.

[0047] Reference Figure 7 In some embodiments of this application, the sleeve 312 has a through hole extending axially; the flipping component 31 also includes an adjusting rod 315, one end of which passes through the through hole and is threaded to the flipping arm 311, and the other end of the adjusting rod 315 has a limiting part 3151 with a size larger than the through hole. By rotating the adjusting rod 315, the relative position between the flipping block 32 (i.e., the anti-smashing foot 200) and the positioning block 22 (i.e., the steel ladle 100) can be easily adjusted, facilitating debugging.

[0048] Reference Figures 5 to 7 In some embodiments of this application, the anti-smashing foot mounting assembly 3 further includes a flipping drive 34, which includes a drive motor 341, a worm gear 342, and a worm wheel 343. The drive motor 341 is mounted on the sliding frame 22, and both the worm gear 342 and the worm wheel 343 are rotatably mounted on the sliding frame 22. The worm gear 342 is connected to the output shaft of the drive motor 341, and the worm gear 342 meshes with the worm wheel 343. The flipping arm 311 is radially connected to the worm wheel 343. The engagement between the worm wheel 343 and the worm gear 342 achieves a self-locking function, so the flipping arm 311 will not rotate after the drive motor 341 stops outputting. Additionally, the anti-smashing foot mounting assembly 3 also includes a positioning element, which is disposed on the flipping element 31. The positioning element is used to position the flipping angle of the flipping element 31 by abutting against the sliding frame 22. Because there may be tooth clearance at the meshing position of the worm gear 343 and worm 342, under the action of the positioning post 35, when the tilting arm 311 tilts to align the anti-smashing foot 200 in the second positioning groove 321, the positioning post 35 abuts against the sliding frame 22, thereby eliminating the influence of tooth clearance and ensuring that the positional accuracy of the anti-smashing foot 200 matches that of the ladle 100. A protective cover 344 is installed over the tilting drive 34 to prevent foreign objects from being drawn in.

[0049] It should be noted that the aforementioned sock mounting assembly 1, steel ladle mounting assembly 2, and anti-smashing foot mounting assembly 3 can be implemented individually or in any combination of two sets. However, when the steel ladle mounting assembly 2 is not implemented, but the anti-smashing foot mounting assembly 3 is required, the positioning part 411 at the toe 41 position of the last body 4 should be adjusted to the instep position of the last body 4 (i.e., the installation position corresponding to the anti-smashing foot 200) so that the anti-smashing foot 200 can be positioned by the positioning part 411.

[0050] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
