Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology for shoe upper cutting, and more specifically, to an automatic feeding device for shoe upper cutting. Background Technology

[0002] When making shoes, the sole and upper are usually manufactured separately, and the finished upper is sewn to the sole to complete the shoe production. The upper production requires cutting the fabric or leather, and the cutting process requires a feeding device to feed the fabric or leather. Therefore, an automatic feeding device for upper cutting is proposed.

[0003] Existing automatic feeding equipment for shoe upper cutting typically mounts a roll of fabric on a rotating shaft and uses a take-up roller to pull the fabric, thereby achieving feeding. However, when fabrics come in various sizes, the fabric roll mounted on the rotating shaft will skew when pulled, thus affecting the cutting effect. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic feeding device for shoe upper cutting. The technical problem to be solved is that it is difficult to restrict the fabric rolls of different sizes, which makes the fabric rolls prone to deflection during the pulling process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for shoe upper cutting, comprising a first fixed frame:

[0006] The first fixed frame has a rotating shaft hinged inside, and a roll of cloth is movably provided on the outer surface of the rotating shaft. The first fixed frame also has a guide roller hinged inside, and a meter counter is fixed on one side of the first fixed frame. The meter counter has a relay inside.

[0007] The outer surface of the rotating shaft is provided with two clamping and limiting devices that can clamp fabric rolls of different sizes and fix the fabric rolls to the outer surface of the rotating shaft.

[0008] The clamping and limiting device includes a clamping plate, which is movably disposed on the outer surface of the rotating shaft and is adapted to the rotating shaft.

[0009] In a preferred embodiment, the rotating shaft is provided inside the rotating shaft, and a connecting plate is fixedly provided on one side of the clamping plate.

[0010] In a preferred embodiment, the connecting plate has an insertion hole inside, the diameter of which is the same as the width of the groove.

[0011] In a preferred embodiment, a bolt is inserted into the socket and the groove, and a nut is threaded onto one end of the bolt. The outer diameter of the nut is larger than the width of the groove.

[0012] In a preferred embodiment, a cutting table is provided on one side of the first fixing frame, and a second fixing frame is provided on one side of the cutting table. Both the cutting table and the second fixing frame are fixed to the ground.

[0013] In a preferred embodiment, a take-up roller is hinged inside the second fixed frame, and a rotating motor is fixedly mounted on one side of the second fixed frame. The output end of the rotating motor passes through one side of the second fixed frame and is fixedly connected to one end of the take-up roller.

[0014] In a preferred embodiment, two clamping rollers are hinged inside the first fixing frame. The fabric roll surrounds the outer surface of the guide roller and passes between the two clamping rollers. A hinge rod is fixed inside the first fixing frame, and an encoder is hinged to the outer surface of the hinge rod through the hinge frame.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model uses a rotating shaft inserted into the fabric roll to restrict the fabric roll to the surface of the rotating shaft. The fabric roll is clamped by two clamping plates, and bolts are inserted into the insertion holes and sliding grooves to fix the position of the clamping plates. Therefore, it can restrict the fabric roll and prevent the fabric roll from moving when the fabric roll is being pulled. Furthermore, the adjustability of the two clamping plates allows for the clamping of fabric rolls of different sizes, expanding the scope of application and avoiding the impact of fabric roll displacement on the cutting effect of the shoe upper.

[0017] 2. This utility model uses rollers at both ends of the encoder to rotate on the fabric. When the fabric is pulled, the encoder transmits data to the meter counter, thereby recording the length of the fabric. Through the relay inside the meter counter, when the length of the fabric pulled reaches a predetermined value, the circuit of the rotating motor can be cut off, thereby achieving automatic feeding. After the fabric is cut, the rotating motor continues to work and repeats the above operation, improving the efficiency of automatic feeding and reducing unnecessary manual operation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art of automatic feeding for shoe upper cutting without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 and 2As shown, this utility model provides an automatic feeding device for shoe upper cutting, including a first fixed frame 1: a rotating shaft 9 is hinged inside the first fixed frame 1, and a fabric roll 8 is movably mounted on the outer surface of the rotating shaft 9; a guide roller 3 is hinged inside the first fixed frame 1; a meter counter 13 is fixedly mounted on one side of the first fixed frame 1; a cutting table 5 is mounted on one side of the first fixed frame 1; a second fixed frame 4 is mounted on one side of the cutting table 5; both the cutting table 5 and the second fixed frame 4 are fixed to the ground; a take-up roller 7 is hinged inside the second fixed frame 4; a rotating motor 6 is fixedly mounted on one side of the second fixed frame 4; the output end of the rotating motor 6 passes through one side of the second fixed frame 4; and the output end of the rotating motor 6 is fixedly connected to one end of the take-up roller 7; two clamping rollers 10 are hinged inside the first fixed frame 1; the fabric of the fabric roll 8 surrounds the outer surface of the guide roller 3 and passes between the two clamping rollers 10; a hinge rod 12 is fixedly mounted inside the first fixed frame 1; and an encoder 11 is hinged to the outer surface of the hinge rod 12 through a hinge frame.

[0027] In order to be able to clamp fabric rolls of different sizes, expand the scope of application, and avoid the impact of fabric roll 8 on the cutting effect of shoe upper, the outer surface of the rotating shaft 9 is provided with two clamping limiting devices 2 that can clamp fabric rolls 8 of different sizes and fix the fabric rolls 8 to the outer surface of the rotating shaft 9.

[0028] like Figure 4 As shown, the clamping and limiting device 2 includes a clamping plate 22, which is movably disposed on the outer surface of the rotating shaft 9. The clamping plate 22 is adapted to the rotating shaft 9, and the rotating shaft 9 is internally provided. A connecting plate 23 is fixedly provided on one side of the clamping plate 22. An insertion hole 24 is provided inside the connecting plate 23. The diameter of the insertion hole 24 is the same as the width of the slide groove 21. A bolt 25 is inserted into the insertion hole 24 and the slide groove 21. A nut 26 is threaded to one end of the bolt 25. The outer diameter of the nut 26 is larger than the width of the slide groove 21. The fabric is inserted through the rotating shaft 9. Inside the roll 8, the fabric roll 8 is restricted to the surface of the rotating shaft 9. The fabric roll 8 is held by two clamping plates 22, and bolts 25 are inserted into the insertion hole 24 and the slide groove 21 to fix the position of the clamping plates 22. Therefore, the fabric roll 8 can be restricted. When the fabric roll 8 is being pulled, it can prevent the fabric roll 8 from moving. Furthermore, the adjustability of the two clamping plates 22 can be used to clamp fabric rolls 8 of different sizes, expanding the range of applications and avoiding the impact of the fabric roll 8's offset on the cutting effect of the shoe upper.

[0029] The working principle is as follows: When using this utility model, the fabric roll 8 is placed on the outer surface of the rotating shaft 9, and the fabric is wrapped around the surface of the guide roller 3 and inserted between the two clamping rollers 10. The fabric is displayed on the cutting table, and one end of the fabric is connected to the outer surface of the winding roller 7. The fabric roll 8 is restricted and fixed by the clamping and limiting device 2, and the fabric roll 8 is fixed on the rotating shaft 9. The rotating motor 6 and the winding roller 7 pull the fabric, thereby realizing automatic feeding. The encoder 11 and the meter counter 13 can be used to set the number of meters of fabric to be pulled, thereby achieving the effect of intermittent feeding. Overall, the problem of fabric roll 8 shifting when pulling the fabric is avoided, and the automatic feeding efficiency of the fabric is improved.

[0030] In addition, it is worth noting that the encoder 11 and the meter counter 13 in this utility model are connected by a data transmission line. The connection circuit and structure are mature existing technologies. Furthermore, the meter counter 13 is equipped with a relay, which is connected to the rotating motor 6 by a wire. The circuit and structure are also mature existing technologies. Therefore, no further details will be provided in this utility model.
