By starting the motor 33, the shoe last 32 can be driven to rotate with the axis of the first connecting rod 31 as the rotation center. In the embodiment of the present application, the rotation center of the shoe last 32 passes through the geometric center of the shoe last 32.

[0023] A second connecting rod 41 is fixedly installed horizontally on a surface of the second supporting column 22 close to the first supporting column 21, and a third connecting rod 42 is also fixedly connected to the end of the second connecting rod 41 away from the second supporting column 22, and the axis of the third connecting rod 42 is perpendicular to the axis of the second connecting rod 41. A fourth connecting rod 43 is respectively installed along the axial direction of the third connecting rod 42, and a first elastic member 45 is provided on the third connecting rod 42 for driving the two fourth connecting rods 43 to slide toward the middle of the third connecting rod 42. A fifth connecting rod 44 is also connected to the fourth connecting rod 43 for sliding along the axial direction of the fourth connecting rod 43, and a second elastic member 46 is provided on the fourth connecting rod 43 for driving the fifth connecting rod 44 to slide away from the third connecting rod 42. A resisting member and a smearing member are provided on the end of the fifth connecting rod 44 away from the third connecting rod 42, and the resisting member is located on the side close to the working space, and the smearing member is located on the side away from the working space. The resisting member is used to resist the shoe upper ground, and the smearing member is used to apply glue to the side of the shoe upper.

[0024] Specifically, the first elastic member 45 is a first spring, and two first guide rods are coaxially fixedly connected at both ends of the third connecting rod 42. The first spring is sleeved on the first guide rod, and a blocking piece is fixedly connected to the end of the first guide rod away from the third connecting rod 42. An end of the fourth connecting rod 43 close to the first connecting rod is fixedly connected to a sleeve, and the sleeve is slidably sleeved on the first guide rod, and a limiting groove is provided on the first guide rod. The sleeve cooperates with the limiting groove so that it can only slide in a straight line. One end of the first spring abuts against the blocking piece, and the other end abuts against the sleeve on the fourth connecting rod 43.

[0025] The second elastic member 46 is a second spring, and a sliding groove is coaxially provided at one end of the fourth connecting rod 43 away from the third connecting rod 42. The fifth connecting rod 44 slides through the sliding groove on the fourth connecting rod 43. The sliding groove of the fourth connecting rod 43 and the fifth connecting rod 44 are both provided with anti-slip structures. The second spring is installed in the sliding groove of the fourth connecting rod 43, and one end of the second spring abuts against the bottom wall of the sliding groove of the fourth connecting rod 43, and the other end abuts against the fifth connecting rod 44.

[0026] The abutment member is specifically a ball bearing 51, which includes a bearing seat and a ball rollingly mounted on the bearing seat. The bearing seat of the ball bearing 51 is fixedly mounted on the fifth connecting rod 44, and the ball of the ball bearing 51 is used for rolling contact with the bottom surface of the shoe upper.

[0027] Reference Figure 4 The smearing member includes a glue outlet pipe 61, a glue delivery cylinder 62 and a glue tank 63. The glue tank 63 is fixedly mounted on the second connecting rod 41, the second support column 22 or the base 1. The glue tank 63 is used to store glue. Two hoses are connected to the glue tank 63. The hose is provided with a water pump 64 to pump glue. The glue outlet pipe 61 is mounted on the fifth connecting rod 44 and is located on the side of the ball bearing 51 away from the workpiece, and is located in the direction of the ball bearing 51 away from the fifth connecting rod 44. The end of the hose away from the glue tank 63 is connected to the inlet end of the glue outlet pipe 61, and the outlet end of the glue outlet pipe 61 faces the working space. The delivery cylinder is located at the outlet of the glue outlet pipe 61, and a gap is reserved between the outlet end of the glue outlet pipe 61 and the glue outlet pipe 61 for glue to pass through. In the embodiment of the present application, the glue outlet pipes 61 on the two fifth connecting rods 44 are both arranged vertically. In other embodiments, the axis of the glue outlet pipe 61 is specifically parallel to the axis of the third connecting rod 42. The rubber feeding cylinder 62 is connected to a rotating shaft, and the rubber feeding cylinder 62 is rotatably connected to the fifth connecting rod 44 via the rotating shaft. The axis of the rubber feeding cylinder 62 is parallel to the rotation axis of the first connecting rod. The rubber feeding cylinder 62 is used for rolling contact with the side wall of the shoe upper.

[0028] When applying glue to the edge of the shoe upper, first manually push the fifth connecting rod 44 and the fourth connecting rod 43 on the second support column 22 to compress the first elastic member 45 and the second elastic member 46 to widen the working space, then put the shoe upper on the shoe last 32, loosen the fifth connecting rod 44 and the fourth connecting rod 43, so that the ball bearing 51 on the fifth connecting rod 44 rolls and contacts the bottom wall of the shoe upper under the action of the second elastic member 46, and the glue delivery tube 62 rolls and contacts the side wall of the shoe upper under the action of the first elastic member 45. The motor 33 on the first support column 21 is started to drive the shoe last 32 and the shoe upper to rotate, and the water pump 64 on the glue tank 63 is started to inject glue into the glue outlet pipe 61. During the rotation of the shoe last 32, the ball bearing 51 always maintains a rolling contact state with the bottom wall of the shoe upper under the action of the second elastic member 46. At the same time, the glue delivery tube 62 maintains pressure contact with the side wall of the shoe upper and rolls on the outer side of the shoe upper as the shoe last 32 rotates. During the rotation of the glue delivery tube 62, the glue in the glue outlet pipe 61 is delivered and smeared on the side wall of the shoe upper. The glue can be smoothly applied to the shoe upper along the bottom arc of the shoe upper, thereby improving the gluing effect on the shoe upper.

[0029] Furthermore, the surface of the glue delivery tube 62 can be set to a hollow state, so that more glue can be stored. When the glue delivery tube 62 is squeezed, the hollow surface of the glue delivery tube 62 is elastic, and the glue can be squeezed and applied to the upper. Furthermore, the interior of the glue delivery tube 62 is provided with a glue storage cavity 65 connected to the surface of the glue delivery tube 62. When the water pump 64 slowly fills the glue tank 63 with glue, the gap between the uppers is changed, and the glue can be stored in the glue storage cavity 65. Furthermore, an electric heating wire 66 is provided in the rotating shaft of the glue delivery tube 62, and the glue in the glue delivery tube 62 can be heated and softened by the heating wire to maintain the fluidity of the glue.

[0030] Furthermore, the second connecting rod 41 is provided with a linkage member for synchronously driving the two fourth connecting rods 43 to move away from each other, and the linkage member includes a sliding paddle 71 and a transmission rod 72. The sliding paddle 71 is slidably arranged on the second connecting rod 41 along the length direction of the second connecting rod 41, and two transmission rods 72 are hingedly arranged on the sliding paddle 71. One end of the two transmission rods 72 away from the sliding paddle 71 is respectively hinged to two connecting sleeves. When the two fourth connecting rods 43 need to be lifted upward and accommodate the shoe upper, the two fourth connecting rods 43 can be pushed away to both sides by the two transmission rods 72 by moving the wave paddle toward the third connecting rod 42, thereby expanding the working space and improving the convenience of using the device.
