Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a shaping machine unit for gluing an upper surface and a bottom surface of a shoe. Background Art

[0002] Shoe pressing is an important process to ensure shoe quality. Traditional shoemaking machines place the glued shoes and soles together in a glue press for glue pressing. However, in actual applications, it is found that since conventional glue presses push the shoes upward for a certain height before pressing during the glue pressing process, the position of the pressed shoes relative to the glue pressing groove does not change. Therefore, the shoes need to be manually removed before and after glue pressing. Since the glue pressing position is located at the bottom of the glue pressing groove and the space is limited, the shoes can only be pulled out from the top. This can easily cause cracking of the glue pressing position between the upper and the bottom of the shoes after glueing, and easily cause the glue to loosen, affecting the bonding stability of subsequent applications. For this reason, a shaping unit for gluing the upper and the bottom is proposed. Utility Model Content

[0003] Based on this, it is necessary to provide a molding unit for gluing the upper and bottom surfaces to address the above technical problems, and to set an ejector plate in the conventional gluing space. In this way, after the gluing is completed, the ejector plate can be ejected from the gluing space as the operating table falls back. In this way, the shoe can be ejected at the bottom of the shoe without pulling the upper, which is beneficial to the stability of the adhesive surface.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The interior of the glue pressing seat has a glue pressing space, the bottom of the glue pressing seat has a through groove, an ejection plate is placed in the through groove, and a limit block connected to the through groove is fixed below the ejection plate;

[0007] Among them, an ejector rod is fixed to the bottom of the ejector plate, one end of the ejector rod passes through the cavity and is slidably sleeved with a sleeve, a spring connected to the ejector rod is fixed in the sleeve, and a locking structure is also provided on the surface of the ejector rod, which can lock the relative length of the sleeve and the ejector rod.

[0008] Furthermore, the locking structure includes a sliding cavity located on one side of the sleeve, a locking block is slidably provided in the sliding cavity, the end of the locking block has an arc-shaped avoidance surface, and a locking groove adapted to the locking block is opened on one side of the ejection rod.

[0009] Furthermore, the tail end of the locking block is connected to a transmission rope, and a reset spring is sleeved on the surface of the transmission rope. The two ends of the reset spring are respectively fixed to the locking block and the side wall of the sliding cavity.

[0010] Furthermore, the locking structure also includes a guide seat fixed to the surface of the body, a pedal is slidably provided in the guide seat, and one end of the transmission rope passes through the outside of the sliding cavity and is fixed to the pedal.

[0011] Furthermore, a first hydraulic telescopic rod is provided at the front and rear ends of the glue pressing seat, and a head pressing block connected to the output end of the first hydraulic telescopic rod is provided in the glue pressing space.

[0012] Furthermore, a second hydraulic telescopic rod is provided on both the left and right sides of the glue pressing seat, and a side pressure block connected to the output end of the second hydraulic telescopic rod is provided in the glue pressing space.

[0013] Furthermore, a rubber pressing block is provided on the inner side of the side pressing block.

[0015] Furthermore, the driving structure also includes a third hydraulic push rod installed in the cavity and connected to the bottom of the connecting frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The molding unit for gluing the upper and bottom surfaces provided by the utility model is designed with an ejector plate in the gluing space. In this way, after the shoes are placed in the gluing space and the gluing seat is moved up for gluing, there is no need to manually take out the shoes.

[0031] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0032] Example 1

[0033] Please refer to Figure 1-Figure 7 As shown, a shaping unit for gluing the upper and bottom surfaces of a shoe comprises a machine body 1 and an operating table 11 provided on the machine body 1. A positioning assembly 19 is mounted on the top of the machine body 1. The positioning assembly 19 is a retractable hydraulic telescopic rod, and its end, which is close to the end of the operating table 11, is connected to a pressing block. In this embodiment, there are two positioning assemblies 19, that is, two pressing blocks. In actual application, the two pressing blocks will respectively press the two ends of the shoe together. Since the positioning structure and principle of the positioning assembly 19 are already well known to those skilled in the art, there is no need to further elaborate on them in this embodiment.

[0034] The bottom of the body 1 is provided with a cavity 12, and the four corners of the operating table 11 are slidably inserted with guide rods 13, and the tops of the multiple guide rods 13 are commonly fixed with a glue pressing seat 14, and the bottoms of the multiple guide rods 13 are commonly provided with a driving structure 15. The glue pressing seat 14 can be driven to slide along the height direction of the guide rod 13 through the action of the driving structure 15. In this way, when the shoes are glued, the shoe last will be placed inside the shoe, and then the shoe with the shoe last will be placed inside the glue pressing seat 14, and then the positioning component 19 will be straightened to form Figure 2 In the state shown, the driving structure 15 then drives the glue pressing seat 14 to move upward, so that the ends of the positioning assembly 19 abut against the two ends of the shoe to form a squeezing state on the shoe, thereby promoting the pressing of the sole and the upper surface;

[0035] The following is an improvement made by this embodiment compared to the conventional molding unit, that is, the glued shoe can be ejected from the glue pressing seat 14 at the bottom of the shoe without pulling the upper surface, as follows:

[0036] The interior of the glue pressing seat 14 has a glue pressing space 16, and the bottom of the glue pressing seat 14 has a through groove 17. The ejector plate 2 is placed in the through groove 17. A limit block 18 connected to the through groove 17 is fixed below the ejector plate 2. The limit block 18 can prevent the ejector plate 2 from being exposed when placed in the through groove 17.

[0037] Among them, the bottom of the ejector plate 2 is fixed with an ejector rod 21, one end of the ejector rod 21 passes through the cavity 12 and is slidably sleeved with a sleeve 22, the sleeve 22 is fixed inside the cavity 12, and a spring 23 connected to the ejector rod 21 is fixed in the sleeve 22. Figure 5 As shown, the spring 23 is in a natural state at this time, and a locking structure 3 is further provided on the surface of the ejector rod 21. The locking structure 3 can lock the relative lengths of the sleeve 22 and the ejector rod 21;

[0038] Furthermore, the locking structure 3 includes a sliding cavity 31 located on one side of the sleeve 22, a locking block 32 is slidably provided in the sliding cavity 31, the end of the locking block 32 has an arc-shaped avoidance surface 33, and a locking groove 34 adapted to the locking block 32 is formed on one side of the ejector rod 21;

[0039] like Figure 5 As shown, at this time, the state of the molding unit is that the upper is not glued. When the shoe needs to be glued, the shoe with the shoe last is placed in the glue pressing space 16 so that the bottom of the shoe contacts the surface of the ejector plate 2, and then the driving structure 15 is started to move the glue pressing seat 14 upward. During the movement, the ejector plate 2 will move in height synchronously. At this time, the ejector rod 21 at the bottom of the ejector plate 2 will slide inside the sleeve 22 and drive the spring 23 to stretch. When the glue pressing seat 14 moves up to the fixed glue pressing position, it contacts and squeezes the positioning component 19;

[0040] At this time, the ejector rod 21 is locked with the corresponding locking block 32 through the locking groove 34 on one side. Figure 6 As shown, after a period of rest, the shoe is glued and the driving structure 15 is used to move the glue pressing seat 14 downward and reset. During the downward movement, the locking block 32 and the locking groove 34 form a locked state, so the height of the ejection plate 2 can remain unchanged. In this way, when the glue pressing seat 14 is completely reset, the ejection plate 2 can partially or completely eject the shoe from the glue pressing space 16. The ejection process is carried out at the bottom of the shoe, so that no pulling is caused between the upper and the sole, thereby not affecting the stability of the glue setting. The exposed shoes also make it easier to take out the shoes. Compared with the shoes after conventional setting, there is no need to pull with greater strength to affect the setting effect.

[0041] Furthermore, a transmission rope 35 is connected to the tail end of the locking block 32, and a return spring 36 is sleeved on the surface of the transmission rope 35. The two ends of the return spring 36 are respectively fixed to the locking block 32 and the side wall of the sliding cavity 31;

[0042] The locking structure 3 further includes a guide seat 37 fixed to the surface of the body 1. A pedal 38 is slidably provided in the guide seat 37. One end of the transmission rope 35 passes through the outside of the sliding cavity 31 and is fixed to the pedal 38.

[0043] After the shoes are glued and ejected, the pedal 38 can be stepped on to move it downward, and then the arc-shaped locking block 32 can be slid by the transmission rope 35 to release the locked state between the arc-shaped locking block 32 and the locking groove 34. At this time, the ejection plate 2 can be dropped to a certain height by the action of the spring 23 and gravity, and then the shoes can be taken out. After the shoes are taken out, the ejection plate 2 can be completely dropped into the through groove 17 without the obstruction of the shoes, so that the next glueing operation will not be affected.

[0044] Example 2

[0045] The molding unit for gluing the upper and bottom surfaces provided in Example 1 is further optimized. Specifically, Figure 4 As shown, the front and rear ends of the glue pressing seat 14 are provided with first hydraulic telescopic rods 140, and the glue pressing space 16 is provided with a head pressing block 141 connected to the output end of the first hydraulic telescopic rod 140. When the two first hydraulic telescopic rods 140 are activated, the head pressing block 141 thereon can slide inside the glue pressing seat 14, so that the glue pressing operation of the front and rear ends of the shoes can be realized;

[0046] The left and right sides of the glue pressing seat 14 are both provided with second hydraulic telescopic rods 142 , and the glue pressing space 16 is provided with a side pressure block 143 connected to the output end of the second hydraulic telescopic rod 142 ;

[0047] A rubber pressing block 144 is provided on the inner side of the side pressing block 143. The side pressing block 143 on it can be moved by starting the second hydraulic telescopic rod 142, so that the gluing operation can be performed on both sides of the shoe. In this way, in conjunction with the above-mentioned first hydraulic telescopic rod 140, an effective gluing and shaping operation can be achieved at the connection between the shoe upper surface and the ground. In actual application, a rubber pressing block can also be set between the head pressing block 141 and the shoe. The setting of the rubber pressing block can effectively disperse the force during extrusion to better fit the shape of the shoe and ensure the gluing effect.

[0048] Example 3

[0049] The shaping unit for gluing the upper and bottom surfaces provided in the first or second embodiment is further optimized, such as Figure 6 As shown, the driving structure 15 includes a connecting frame 150, and the bottom ends of the plurality of guide rods 13 extend into the cavity 12 and are fixed to the surface of the connecting frame 150. The surface of the connecting frame 150 has a groove for the ejection rod 21 to pass through.

[0050] The driving structure 15 also includes a third hydraulic push rod 151 installed in the cavity 12 and connected to the bottom of the connecting frame 150. When the third hydraulic push rod 151 is started, its output end can drive the connecting frame 150 to move in the height direction, so that the multiple guide rods 13 on the connecting frame 150 can be driven, and the height of the shoes on the glue pressing seat 14 can be raised and lowered.
