A fully automatic gluing equipment for footwear production

Abstract

The present invention discloses a fully automatic gluing device for footwear production, including a support body, wherein the support body includes a bottom plate, a middle plate and an upper plate distributed from bottom to top; a placement opening for placing the sole is provided at the upper end of the bottom plate; a coating component for coating glue on the sole is installed at the lower end of the middle plate, and the coating component has the same shape as the placement opening and can be embedded in the placement opening.

When the glue in the cone shape of the sole is squeezed with the upper, the glue is spread out by force, and the coating area is increased, so that the glue is prevented from being coated too little, and the glue coating area is also increased, and it is difficult for the glue to overflow due to excess.

Description

Technical Field

[0001] The invention relates to the technical field of shoe manufacturing, in particular to a fully automatic glue coating device for shoe production. Background Art

[0002] In the process of shoe processing, the adhesion of the sole and the upper is an important link, which usually requires the use of glue. First, use an appropriate detergent or solvent to thoroughly clean the bonding surface of the sole and the upper to remove oil, dust and other impurities. Make sure the bonding surface is dry and free of moisture. Use a brush, roller or other professional glue application tools to evenly apply glue to the bonding surface of the sole and the upper. Be careful to avoid too much or too little glue, make sure each part is applied in place, align the sole with the upper, and make sure each part fits tightly. For complex shoe structures, you can use a clamp or tool to maintain the alignment. Use appropriate pressure (such as heavy objects, presses) to apply pressure to the sole and upper to ensure that the bonding is completely fitted.

[0003] The above is a general process of gluing shoes. However, in the process of gluing the soles, although the glue can be applied by the gluing equipment, the uniformity is difficult to control. Even if the glue can be applied evenly, it is still difficult to control the amount of glue applied. If too much glue is applied, the glue is likely to overflow during the gluing process, resulting in a waste of glue. If too little glue is applied, the shoes can be adhered, but the adhesion is limited, resulting in the quality of the shoes being affected. Based on this, a device that can automatically gluing the soles and apply an appropriate amount of glue is needed. Summary of the invention

[0004] The object of the present invention is to provide a fully automatic glue coating device for footwear production to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a fully automatic gluing device for footwear production, comprising a bracket body, wherein the bracket body comprises a bottom plate, a middle plate and an upper plate distributed from bottom to top;

[0006] The upper end of the bottom plate is provided with a placement opening for placing the sole;

[0007] A coating component for coating glue on the sole is installed at the lower end of the middle plate, and the shape of the coating component is the same as that of the placement opening, and the coating component can be embedded in the placement opening;

[0008] A glue frame for holding glue is installed on the upper plate, and a liquid inlet and a discharge portion are installed between the upper plate and the middle plate, and the glue frame is connected to the coating assembly through the liquid inlet and the discharge portion;

[0009] Wherein, a pump body for discharging glue is installed in the glue frame, and the glue in the glue frame is discharged into the coating component through the pump body, and the coating component adheres the glue to the sole.

[0010] Furthermore, a cylinder is installed at the lower end of the base plate, and a support shaft is fixed at the lower end of the middle plate. The support shaft passes through the base plate downward and can slide along the base plate. The output end of the cylinder passes through the base plate and is fixed to the middle plate upward to drive the middle plate to move in the up and down directions.

[0011] Furthermore, the coating assembly includes an outer frame, a coating frame 1 and a coating frame 2, the outer frame is fixed at the lower end of the middle plate, the outer frame can be embedded in the placement port, the coating frame 1 is set into the outer frame, the coating frame 2 is set into the coating frame 1, the outer side of the coating frame 1 is fitted with the inner side of the outer frame, the upper ends of the coating frame 1 and the coating frame 2 are fixedly connected with a connecting tube 1 and a connecting tube 2 which are connected to the interior thereof, the connecting tube 1 is used for injecting glue, the connecting tube 2 is used for exhausting gas, the upper end of the connecting tube 1 is connected to the liquid inlet part, and the connecting tube 2 is connected to the exhaust part.

[0012] Furthermore, the cross-sections of the coating frame 1 and the coating frame 2 are both inverted U-shaped, and the open side thereof allows the glue to contact the sole. When the sole is coated, the sole contacts the coating frame 1 and the coating frame 2.

[0013] Furthermore, the coating frame 1 and the coating frame 2 are both ring-shaped, and their shapes are the same as the shape of the sole.

[0014] Furthermore, the liquid inlet part includes a liquid inlet pipe 1 and a liquid inlet pipe 2 which are connected to each other, and the liquid inlet pipe 1 and the liquid inlet pipe 2 are respectively fixed to the upper plate and the middle plate, and the liquid inlet pipe 1 and the liquid inlet pipe 2 are respectively connected to the glue frame and the connecting pipe 1.

[0015] Furthermore, a partition is fixed inside the second liquid inlet pipe, and a connecting hole passes through the partition from top to bottom. The connecting hole is larger at the top and smaller at the bottom, and the inner wall of the connecting hole has a smooth transition. An outer support plate with a gap between the partition and the partition is fixed at the lower end of the partition, a support spring is fixed at the upper end of the outer support plate, and a spacer ball located in the connecting hole is fixed at the upper end of the support spring. The spacer ball passes through a hole from top to bottom, and the hole and the connecting hole are used to control the flow rate of glue.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] 1. After the glue is filled in the coating frame 1 and the coating frame 2, the coating components are separated upwards, and local glue will adhere to the sole. The glue adhered to the sole will be in a cone shape. This is because the glue is viscous. When the glue in the cone shape of the sole is squeezed with the upper, the glue is spread out by force, increasing the coating area, preventing the glue from being coated too little, and the glue coating area is also increased, and it is difficult for the glue to overflow due to excess.

[0019] 2. When applying glue on the sole, only the glue is needed to fill the first and second coating frames, which is convenient for operation, simple in structure, and easy to control the amount of glue applied.

[0020] 3. The glue enters the liquid inlet and moves through the connecting holes on the spacer. The glue will push the spacer ball downward to make the connecting holes smaller, thereby preventing the air in the coating frame 1 and the coating frame 2 from being unable to be discharged due to excessive flow rate. The glue in the coating frame 1 and the coating frame 2 will flow slowly to squeeze out the air and avoid gaps during coating. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 9 The present invention provides a technical solution: according to the material, purpose and process requirements of the shoes, a suitable type of glue is selected. High-quality glue can ensure the close combination of various parts of the shoes, thereby improving the overall quality of the shoes. Before applying the glue, the adhesive surfaces of the sole and the upper need to be purified to remove dust, oil and other impurities. This is usually done by mechanical dust removal using a bristle brush wheel or by blowing dust removal using compressed space air. After that, the glue is applied to the sole, and then the upper is adhered to the sole through the glue. Currently, there are mechanized and manual gluing methods. When applying the glue, it is necessary to control the amount of glue applied and the coating area. The system for controlling the coating is relatively complex. Based on this, the glue needs to be applied. A fully automatic gluing device for footwear production includes a bracket body 1. The bracket body 1 includes a bracket body distributed from bottom to top. The bottom plate 2, the middle plate 3 and the upper plate 7; the upper end of the bottom plate 2 is provided with a placement opening 21 for placing the sole; the lower end of the middle plate 3 is provided with a coating component 6 for coating glue on the sole, the shape of the coating component 6 is the same as the shape of the placement opening 21, and it can be embedded in the placement opening 21; the upper plate 7 is provided with a glue frame 71 for holding glue, and a liquid inlet portion 8 and a discharge portion 9 are provided between the upper plate 7 and the middle plate 3, and the glue frame 71 is connected with the coating component 6 through the liquid inlet portion 8 and the discharge portion 9;

[0034] Among them, a pump body for discharging glue is installed in the glue frame 71, and the glue in the glue frame 71 is discharged into the coating component 6 through the pump body. The coating component 6 adheres the glue to the sole. During the working process of the coating component 6, the glue is filled into the coating component 6, and then the glue contacts the sole, so that the glue contacts the sole and partially adheres to the sole. The glue adhered to the sole is considered to have completed the coating. When the sole and the upper are fixed subsequently, the glue is squeezed and dispersed. The dispersed glue can be fully filled between the sole and the upper. Even if there are local bumps, they can be filled with glue. If the glue is evenly applied to the sole first, it is difficult to make enough glue enter the depression of the upper.

[0035] like Figure 1 As shown, a cylinder 5 is installed at the lower end of the bottom plate 2, and a support shaft 4 is fixed to the lower end of the middle plate 3. The support shaft 4 penetrates the bottom plate 2 downward and can slide along the bottom plate 2. The output end of the cylinder 5 penetrates the bottom plate 2 and is fixed to the middle plate 3 upward to drive the middle plate 3 to move up and down. The cylinder 5 is used to control the coating of glue so that the glue is coated on the sole. The cylinder 5 has a simple structure, is easy to operate, and is not easy to be damaged.

[0036] The coating assembly 6 includes an outer frame 61, a coating frame 1 62 and a coating frame 2 63. The outer frame 61 is fixed to the lower end of the middle plate 3, and the outer frame 61 can be embedded in the placement port 21. The coating frame 1 62 is sleeved into the outer frame 61, and the coating frame 2 63 is sleeved into the coating frame 1 62. The outer side of the coating frame 1 62 is fitted with the inner side of the outer frame 61. The upper ends of the coating frame 1 62 and the coating frame 2 63 are fixedly connected with a connecting pipe 1 64 and a connecting pipe 2 65 arranged to communicate with the interior thereof. The connecting pipe One 64 is used for injecting glue, and the connecting tube two 65 is used for exhausting gas. The upper end of the connecting tube one 64 is connected to the liquid inlet part 8, and the connecting tube two 65 is connected to the exhaust part 9. Glue can enter the coating frame one 62 and the coating frame two 63. After the glue is adhered to the sole, in the subsequent coating process, the gas in the coating frame one 62 and the coating frame two 63 can also be discharged, and the glue continues to fill the coating frame one 62 and the coating frame two 63, thereby realizing the continuous adhesion of glue to the sole.

[0037] The cross-sections of coating frame 1 62 and coating frame 2 63 are both inverted U-shaped, and one side of the opening allows the glue to contact the sole. When the sole is coated, the sole contacts coating frame 1 62 and coating frame 2 63, wherein the lower ends of coating frame 1 62 and coating frame 2 63 contact the sole, so that the glue fills coating frame 1 62 and coating frame 2 63, and the glue will partially adhere to the sole to achieve the coating effect. The coating frame 1 62 and coating frame 2 63 are inverted U-shaped, so that the glue in coating frame 1 62 and coating frame 2 63 is located on the sole. In addition, when coating frame 1 62 and coating frame 2 63 are slowly separated from the sole, a large amount of glue in coating frame 1 62 and coating frame 2 63 can remain on the sole, avoiding the glue in coating frame 1 62 and coating frame 2 63 from dripping downward, so that the glue on the sole can be squeezed and spread.

[0038] The coating frame 1 62 and the coating frame 2 63 are both in a ring shape, which is the same shape as the sole. The glue can be distributed along the sole, so that the glue can fully fix the sole and the upper.

[0039] The liquid inlet part 8 includes a liquid inlet pipe 81 and a liquid inlet pipe 82 which are connected to each other. The liquid inlet pipe 81 and the liquid inlet pipe 82 are respectively fixed to the upper plate 7 and the middle plate 3. The liquid inlet pipe 81 and the liquid inlet pipe 82 are respectively connected to the glue frame 71 and the connecting pipe 64 for conveying glue. At the same time, they can also be extended and retracted to make the coating assembly 6 move downward.

[0040] A partition 83 is fixed in the liquid inlet pipe 82, and a connecting hole 84 is penetrated from top to bottom of the partition 83. The connecting hole 84 is larger at the top and smaller at the bottom, and the inner wall of the connecting hole 84 is smoothly transitioned. An outer support plate 86 with a gap between the partition 83 is fixed at the lower end of the partition 83, and a support spring 87 is fixed at the upper end of the outer support plate 86. A spacer ball 85 located in the connecting hole 84 is fixed at the upper end of the support spring 87. The spacer ball 85 is penetrated from top to bottom with holes, and the holes and the connecting hole 84 are used to control the flow rate of glue. When the glue passes through the partition 83, the speed of the glue moving downward can be effectively reduced. In addition, when the coating component 6 is separated upward, the glue is prevented from dripping downward under the action of tension. The glue is squeezed downward, which will push the spacer ball 85 downward to make the connecting hole 84 smaller. When the connecting hole 84 is the smallest, the hole penetrated from top to bottom by the spacer ball 85 can also transmit the glue downward to avoid jamming.

[0041] The discharge part 9 includes a discharge pipe 91, a discharge pipe 92, a one-way valve 93 and a fixing sleeve 94. The discharge pipe 91 and the discharge pipe 92 are socketed, and the upper end of the discharge pipe 91 is fixed to the upper plate 7. The fixing sleeve 94 is fixed to the middle plate 3, and its upper end is threadedly connected to the discharge pipe 92. The one-way valve 93 is installed inside the discharge pipe 92 to discharge the gas and avoid gas reflux.

[0042] The working principle of the present invention is as follows: the sole is placed in the placement port 21, and the middle plate 3 is driven downward by the action of the cylinder 5, so that the coating component 6 at the lower end of the middle plate 3 cooperates with the placement port 21, and under the action of the pump body in the glue frame 71, the glue is squeezed from the liquid inlet part 8 into the coating component 6, and because the lower end of the coating component 6 is squeezed with the sole, the air in the coating component 6 moves outward from the discharge part 9, so that the glue is filled into the coating component 6 and contacts with the sole, and a part of the glue adheres to the sole, thereby completing the coating effect.

[0043] In the above process, the outer frame 61 cooperates with the placement port 21 to ensure that the coating frame 1 62 and the coating frame 2 63 are squeezed with the sole, and the coating frame 1 62 and the coating frame 2 63 are sealed except for the connecting pipe 1 64 and the connecting pipe 2 65. When the glue enters the coating frame 1 62 and the coating frame 2 63, the air is squeezed out, and the glue is distributed along the coating frame 1 62 and the coating frame 2 63, that is, the glue can be distributed along the shape of the sole. After the coating frame 1 62 and the coating frame 2 63 are filled with glue, the coating component 6 is separated upward, and the local glue will adhere to the sole and be distributed along the shape of the sole. The glue adhered to the sole will be in a cone shape. This is because the glue is viscous. When the cone-shaped glue of the sole is squeezed with the upper, the glue is spread out under the force, increasing the coating area, preventing the glue from being coated too little, and the glue coating area is also increased, and it is difficult for the glue to overflow excessively.

[0044] In addition, when the glue is applied to the sole, only the glue is needed to fill the first coating frame 62 and the second coating frame 63, which is convenient for operation, has a simple structure, and is easy to control the amount of glue applied.

[0045] After the glue is applied, the coating frame 1 62 and the coating frame 2 63 are separated upward from the sole. Glue will remain on the coating frame 1 62 and the coating frame 2 63 , but due to the viscosity of the glue, the glue is prevented from falling downward.

[0046] After coating frame 1 62 and coating frame 2 63 are matched with the sole, when the liquid inlet part 8 enters the glue, the glue moves along liquid inlet tube 1 81 and liquid inlet tube 2 82, and the glue is blocked by the partition layer 83. The glue moves through the connecting hole 84 on the partition layer 83. In addition, the downward extrusion force is large, and the glue will push the partition ball 85 to move downward, making the connecting hole 84 smaller, avoiding excessive flow rate, which will cause the air in coating frame 1 62 and coating frame 2 63 to be unable to be discharged, so that the glue in coating frame 1 62 and coating frame 2 63 flows slowly, squeezes out the air, and avoids the formation of gaps during coating.

[0047] When the air is discharged, the gas enters the discharge part 9, so that the gas passes through the one-way valve 93 and enters the discharge pipe 2 92. Even if the glue is partially discharged with the movement, the discharge pipe 2 92 can be disassembled and dumped.
