[0001] The present invention relates to the field of shoemaking machinery, in particular to a side pressing structure of a sole pressing machine and the sole pressing machine. Background Art

[0002] The conventional shoe-making sole pressing machine, such as the improvement of the side pressing mechanism disclosed in the new patent case of Taiwan Patent Announcement No. M534538, mainly uses the push rods of a plurality of pressure cylinders to push the corresponding pressure blocks respectively, so as to perform side pressing work on the sole, and the pressure blocks are used to press against the side of the sole accordingly. Therefore, the more the number of pressure blocks is, the better it can fit the curved side of the sole. However, the number of pressure blocks that can be installed in the prior patent is fixed, and the number of pressure blocks cannot be increased according to different needs. Moreover, if the number of pressure blocks is increased only by increasing the number of pressure cylinders, it will only cause the overall volume to become relatively larger and greatly increase its manufacturing cost. Therefore, the practicality of the prior patent is still not ideal.

[0003] For example, the side pressure device of the sole pressing machine for shoe manufacturing disclosed in Taiwan Patent Publication No. M300052 is additionally provided with a spring on each pressing block, and the elastic restoring force provided by the spring enables the pressing block to have an automatic reset function during the retraction stroke. However, its reset structure is too complicated, which is not only not conducive to assembly operation, but also increases its manufacturing cost. There is still room for improvement.

DETAILED DESCRIPTION

[0019] Please refer to Figures 1 to 8 As shown, it shows the specific structure of an embodiment of the present invention.

[0020] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] As shown in FIGS. 1 to 5 , a side pressing structure of a sole pressing machine is disclosed. The side pressing structure mainly comprises two cylinder bodies 11 arranged in parallel and spaced relation on a carrier 1. Since the two cylinder bodies 11 have the same structure, only the detailed structure of the single side cylinder body 11 will be described below: The cylinder body 11 has several cylinder chambers 12 formed therein, and a first flow channel 13 and a second flow channel 14 connected to the cylinder chambers 12 are provided in the cylinder body 11, and a push rod 15 is provided in each cylinder chamber 12, and each push rod 15 has a mounting end 151 protruding out of its cylinder chamber 12 and a force-bearing end 152 extending into its cylinder chamber 12, and a piston 16 located between the first flow channel 13 and the second flow channel 14 is provided on the force-bearing end 152, and a side pressure group 21 is provided on the mounting end 151, so that when the piston 16 of each push rod 15 is pushed by the pressure (such as oil pressure) in the first flow channel 13 and the second flow channel 14, it can drive the side pressure group 21 connected thereto to move forward and backward relative to the cylinder body 11.

[0022] The side pressure group 21 on each assembly end 151 is respectively composed of a base 22 and two movable blocks 23, wherein: the base 22 has a front side 221 and a rear side 222 opposite to the front side 221, the base 22 is fixedly connected to the assembly end 151 of the push rod 15 with its rear side 222, and a protrusion 24 extending in the longitudinal direction and in the shape of a long strip is integrally formed at the central position of the front side 221, and the protrusion 24 is formed with a combination surface 241 on its front end surface for selecting whether to assemble a pressure block, and a slide groove 25 is formed on the left and right opposite sides of the base 22, and each of the slide grooves 25 is respectively provided with the two movable blocks 23, and the two movable blocks 23 are slidably disposed toward A pressing block 26 is respectively connected to the front end 231 of the front side 221, and a connecting rod group 27 is pivoted on the assembly end 151 of the push rod 15 at its middle section. The connecting rod group 27 is composed of two parallel plates 271 arranged at intervals. The two plates 271 are respectively pivoted at their middle sections on an upper beveled plane 153 and a lower beveled plane 154 located at the assembly end 151 through a pivot 272, so that the two ends of the connecting rod group 27 can be movably pivoted, and the rear ends 232 of the two movable blocks 23 protruding toward the rear side 222 are respectively pivotally connected to the two ends of the connecting rod group 27 via a connecting piece 28, so that the two movable blocks 23 and their pressing blocks 26 can be relatively displaced forward and backward.

[0023] Furthermore, the two plates 271 are respectively formed with a planar abutment surface 273 on one side facing the cylinder body 11, and the cylinder body 11 is fixedly provided with a reset block 17 on the end surface facing the base 22. The reset block 17 has a reference plane 171 that is located at the same horizontal height and is relatively arranged with the abutment surfaces 273 of the two plates 271. When the side pressure group 21 moves backward with the retraction stroke of the push rod 15, it can drive the abutment surfaces 273 of the two plates 271 to relatively abut against the reference plane 171 of the reset block 17, thereby forcing the connecting rod group 27 to be forced to pivot and drive the two movable blocks 23 and their pressure blocks 26 to automatically reset to a starting position A that is flush with each other.

[0024] As shown in FIGS. 1 to 5, the assembly surface 241 of the projection 24 is not provided with a pressure block. In this state, the pressure blocks 26 assembled on the two movable blocks 23 cover the assembly surface 241 of the projection 24, and the pressure blocks 26 assembled on the two movable blocks 23 are respectively formed with a groove 261 on the end surface facing the projection 24, so that a buffer space 29 is formed between the groove of each pressure block 26 and the projection 24 for the two pressure blocks 26 to retreat. A linear guide groove 18 is respectively provided on the top surface of each side pressure group 21 of the cylinder body 11, and a guide rod 19 is slidably accommodated in the linear guide groove 18, and the guide rod 19 is relatively fixed to a connecting portion 223 on the top of the base 22 with one end extending outward from the cylinder body 11, so that when the push rod 15 drives the base 22 to move forward and backward, the base 22 will synchronously drive the guide rod 19 to slide along the linear guide groove 18, so as to further ensure the stability of the pushing stroke of the push rod 15.

[0025] In actual use of the present invention composed of the above structure, as shown in FIG. 6, when the user drives the cylinder 11 to move the push rod 15 and its side pressure group 21 forward, and the pressure block 26 of the side pressure group 21 is relatively pressed against the side of the shoe material B with a curvature, when one of the pressure blocks 26 is pressed on the side of the shoe material B, the other pressure block 26 will rotate with the pivot of the connecting rod group 27 to cooperate with the side contour of the shoe material B, so that the side pressure position of the shoe material 21 can be automatically adjusted according to the curvature of the side, and when the side pressure is completed, During the stroke of the push rod 15 moving backward and retracting, the push rod 15 drives the abutment surfaces 273 of the two plates 271 to abut against the reference plane 171, thereby forcing the connecting rod assembly 27 to pivot again, so as to drive the two movable blocks 23 and their pressure blocks 26 to automatically reset to the starting position A flush with each other (as shown in FIG. 5 ). This allows the present invention to have the function of automatic reset of the side pressure structure through its reasonable spatial configuration and relatively simple structural composition, and further has the effect of effectively reducing its manufacturing cost.

[0026] In addition, the side pressure structure provided by the present invention further has the function of increasing the number of pressure blocks according to actual needs through the assembly surface 241 on the protrusion 24. As shown in FIG. 7, another use state of the present invention is that a pressure block is assembled on the assembly surface 241 of the protrusion 24. The difference between the above-mentioned use state and the above-mentioned use state is that the pressure blocks 26 assembled on the two movable blocks 23 are respectively located on the two opposite sides of the protrusion 24, and a plurality of locking holes 242 are provided on the assembly surface 241 of the protrusion 24 for locking a fixed pressure block 31, so that each side pressure group 21 can be used without Under the premise that the cylinder driving structure needs to be modified, the number of the pressing blocks can be simply and quickly increased by directly assembling the fixed pressing block 31 on the assembly surface 241 of the protruding block 24. As shown in FIG. 8, when the push rod 15 drives the side pressure group 21 to move forward, the fixed pressing block 31 and the pressing blocks 26 arranged on the two movable blocks 23 can effectively improve the fit and compliance between the side edge of the shoe material B, and thus the side pressure structure provided by the present invention has the function of increasing the number of pressing blocks according to actual needs, and is very practical.

[0027] Also, a sole pressing machine is provided, which uses the side pressing structure of the sole pressing machine as described in any of the above items.
