Description

Technical Field

[0001] The utility model relates to a shoe processing device, in particular to a pressing head mechanism used for a viscose shoe pressing tool. Background Art

[0002] The gluing process between the sole and the upper is a key step in the shoemaking industry, which aims to firmly bond the upper material to the sole to ensure the overall structural stability and durability of the shoe. The press head used to position the upper plays an important role in this process.

[0003] Chinese patent document CN210726847U discloses a cold-adhesive shoe adhesive pressing mechanism, comprising a base plate for positioning the sole, a guide rod fixed on the base plate, and a pressing assembly slidably arranged on the guide rod, wherein the pressing assembly comprises a pressing plate slidably arranged on the guide rod, and a shoe mold arranged below the pressing plate for positioning the upper, wherein the adhesive surfaces of the sole and the upper are opposite to each other during the pressing process.

[0004] The pressing component in the above scheme is the pressure head of the volume mentioned above. The above scheme uses the cold-adhesive shoe pressing mechanism combined with an external pressure device to mechanically glue and press the cold-adhesive shoe, which can improve the pressing efficiency and further improve the pressing quality of the cold-adhesive shoe during gluing, so that the glue pressing between the upper and the sole is uniform. However, the above scheme has the following shortcomings: when the size of the upper to be processed changes, the above scheme requires the overall replacement of the pressing component for processing, which greatly increases the mold opening cost, and also requires a lot of manpower and material resources for the storage and management of these molds; furthermore, if the pressing component can no longer be used because a certain model is no longer processed, it will lead to mold waste, which will further increase the cost. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a pressing head mechanism for a viscose shoe pressing tool which can adapt to the sizes of various shoe uppers.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a press head mechanism for a viscose shoe press, comprising a fixed frame, on which a press head for matching with a shoe upper is provided, and on which an adjusting device for adjusting the size of the press head is provided, wherein the adjusting device comprises an adjusting button, an adjusting block and a transmission assembly connected between the adjusting button and the adjusting block, wherein the transmission assembly is used to convert the rotation of the adjusting button into a horizontal movement of the adjusting block in a direction away from the center of the press head.

[0007] The beneficial effect of the utility model is that when the adjusting knob is rotated, the rotation of the adjusting knob is converted into horizontal movement of the adjusting block through the transmission assembly, and then the size of the entire pressing head can be conveniently adjusted through the adjusting knob exposed on the outside of the pressing head to adapt to shoe uppers of various sizes, thereby reducing mold costs and improving the use efficiency of a single processing equipment.

[0008] Furthermore, the transmission assembly includes a first gear and first racks respectively meshed on upper and lower sides of the first gear, and the first racks are respectively connected to the adjustment blocks located on the same side.

[0009] Through the transmission cooperation of the gear rack, when the first gear rotates, the first racks respectively meshing on the upper and lower sides of the first gear can move horizontally toward the left or right side, thereby driving the adjustment block located on the side to move horizontally, that is, the adjustment block moves away from the center of the pressure head. Conversely, the same operation can make the adjustment block move toward the center of the pressure head. The above scheme is convenient to operate, low in cost, and easy to implement in production.

[0010] Furthermore, the bottom surface of the pressure head is provided with a fixed block located at the center of the bottom surface, and the number of the adjustment blocks is four and they are arranged at the outer edge of the fixed block in a surrounding manner.

[0011] The four adjustment blocks arranged around the outer edge of the fixed block can be divided into two at the upper end and two at the lower end, and the two adjustment blocks at the upper and lower ends are respectively located on the left and right sides of the end, so that when the four adjustment blocks move away from the center of the fixed block, the size change of the entire pressure head is more consistent, so as to better adapt to the upper and form a stable connection relationship with the upper.

[0012] Furthermore, the transmission assembly also includes a second gear and a second rack respectively meshing on the upper and lower sides of the second gear, and the second rack is respectively connected to the adjustment block located on the same side; a transmission rod is provided between the first gear and the second gear, with its two ends respectively fixed on the first gear and the second gear.

[0013] One end of the transmission rod is fixed on the adjusting button and rotates with the adjusting button, so that the first gear and the second gear fixed on the transmission rod are transmitted synchronously. Therefore, when adjusting the size of the pressure head, the movement of the four adjustment blocks is more consistent, avoiding the situation where inconsistent movement causes the shoe upper to be unable to adapt.

[0014] Furthermore, the pressure head mechanism also includes a pressure rod, the pressure head is connected to the pressure rod, and the fixing frame is provided with a downward pressure gear meshed with the pressure rod and a fixing piece for locking the gear.

[0015] After the pressure rod drives the pressure head to move to the desired position, the fixing piece is inserted into the center of the locking gear and abuts against the surface of the locking gear, thereby positioning the pressure rod by locking the locking gear, thereby facilitating continuous pressure on the product to be processed to improve the yield rate.

[0021] The utility model embodiment is a press head mechanism for a viscose shoe press such as Figure 1-5 As shown, it includes a fixing frame 1 and a pressing head mechanism 2, wherein the pressing head mechanism 2 includes a pressing rod 21 movably connected to the fixing frame 1, a pressing head 22 arranged at the bottom of the pressing rod 21, and an adjusting device 23 arranged on the pressing head 22. The fixing frame 1 is provided with a locking gear 11 meshed with the pressing rod 21. After the pressing rod 21 drives the pressing head to move into position, a fixing member 12 is inserted into the locking gear 11, and the fixing member 12 can be a bolt to abut against the surface of the locking gear to limit the rotation of the locking gear 11, thereby limiting the up and down movement of the pressing rod 21.

[0022] The adjusting device 23 includes an adjusting button 231 disposed on the outside of the pressure head 22, an adjusting block 232 disposed at the bottom of the pressure head, and a transmission assembly 233 located therebetween. A transmission rod 236 is fixed to the back of the adjusting button 231, i.e., the inside of the pressure head 22, so that the transmission rod 236 can rotate with the rotation of the adjusting button 231. Since the second gear and the second rack are consistent in structure with the first gear 234 and the first rack 235, they are not marked in the figure. The first gear 234 and the second gear are fixed to the transmission rod 236, respectively. The first gear 234 is meshed with the first rack 235 on both the upper and lower sides, and the second gear is meshed with the second rack on both the upper and lower sides. A fixed block 221 is provided at the center of the bottom surface of the pressure head 22. The adjusting device 23 also includes four adjusting blocks 232 arranged to surround the fixed block 221. The two first racks 235 are respectively fixed on the adjusting blocks 232 located on the left and right sides of the upper end of the bottom surface of the pressure head 22. The two second racks are respectively fixed on the adjusting blocks 232 located on the left and right sides of the lower end of the bottom surface of the pressure head 22.

[0023] The following is a brief description of the use of this embodiment: when the size of the vamp is too large when processing is required, first turn the adjustment knob 231 to make the transmission rod 236 drive the first gear 234 and the second gear to rotate. When the first gear 234 and the second gear rotate, the first rack 235 and the second rack meshing on the upper and lower sides of the first gear 234 and the second gear respectively move horizontally to the left and right sides, thereby driving the respective connected adjustment blocks 232 to move away from the center of the fixed block 221, thereby adapting to a larger vamp. On the contrary, if the size of the vamp is smaller than the pressure head 22, the adjustment knob 231 is rotated in the opposite direction to make the adjustment block 232 move toward the center of the fixed block, thereby adapting to a smaller size of the vamp.

[0024] The above embodiment is only one of the preferred specific embodiments of the present invention. Common changes and substitutions made by those skilled in the art within the technical solution of the present invention are all included in the protection scope of the present invention.
