Description

Technical Field

[0001] This utility model relates to the field of material supply technology, and in particular to a feeder synchronous film stretching structure and feeder. Background Technology

[0002] Traditional electric feeders mainly consist of a feeding mechanism, a film pulling mechanism, and a film tension detection mechanism. They use asynchronous control to move the tape and tear the film. When the pick-and-place machine issues a feeding command, the feeding mechanism moves the tape forward first. During the tape movement, the film tension decreases, which then triggers the film tension detection mechanism to start the film pulling mechanism to tighten the film. In other words, the feeding mechanism starts working first, and then the film pulling mechanism works. At the end, the feeding mechanism stops working first, and then the film pulling mechanism finally tightens the film and stops through the tension detection mechanism.

[0003] When the tension of the feeder pressure cover spring decreases or the friction between the pressure cover and the feed belt becomes less than the tension of the film due to dirt buildup inside the pressure cover after long-term use, the feed belt will move forward at the predetermined position during feeding, resulting in a problem of material deviating. This is because when the feeding mechanism stops feeding the feed belt to the picking position, the film pulling mechanism continues to work until the film is tightened. Since the friction of the feed belt is less than the tension of the film, the feed belt will move forward under the opposite pulling force of the film. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, this utility model proposes a feeder synchronous film stretching structure and feeder, aiming to solve the problem of unstable material supply of existing electric feeders.

[0005] To solve the above-mentioned technical problems, this application provides a feeder synchronous film stretching structure and a feeder. In a first aspect, this application provides a feeder synchronous film stretching structure, including a film release mechanism and a synchronous electronic control device disposed on the body. The film release mechanism includes a fixed shaft A, a fixed shaft B, a film stretching fixed gear, a film stretching movable gear, a tension spring, an adjusting nut, an adjusting bolt, and a film stretching movable gear bracket. It is characterized by further including a film stretching motor connected to a worm gear; the worm gear meshes with the film stretching fixed gear for transmission, the adjusting nut and the film stretching movable gear are disposed on the film stretching movable gear bracket, and one end of the tension spring is fixed to the other end of the body and to an adjusting screw disposed inside the adjusting nut.

[0006] Preferably, the synchronous electrical control device includes a main control board and a speed regulation module, a film stretching motor, and a feeding motor, all electrically connected to the main control board.

[0007] Preferably, the tension of the film is set by adjusting the tension spring through the adjusting bolt.

[0008] Preferably, the speed control module is used to adjust the speed of the film stretching motor.

[0009] Preferably, the main control board synchronously controls the start and stop of the feeding motor and the film stretching motor, that is, when the feeding motor rotates, the film stretching motor also rotates at the same time, and when the feeding motor stops rotating, the film stretching motor also stops rotating at the same time.

[0010] Preferably, under the same working time, the length of the film pulled by the feeding motor and the film pulling motor is greater than the length of the material belt moving forward.

Detailed Implementation

[0019] The technical solution of this utility model will now be described in detail through specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4As shown, the present invention proposes a feeder synchronous film stretching structure and feeder, including a film release mechanism and a synchronous electronic control device disposed on the body 13. The film release mechanism includes a fixed shaft A 2, a fixed shaft B 9, a film stretching fixed gear 3, a film stretching movable gear 4, a tension spring 5, an adjusting nut 6, an adjusting bolt 7, and a film stretching movable gear bracket 8. It is characterized by further including a film stretching motor 10 connected to the worm gear 1; the worm gear 1 meshes with the film stretching fixed gear 3 for transmission, the adjusting nut 6 and the film stretching movable gear 4 are disposed on the film stretching movable gear bracket 8, and one end of the tension spring 5 is fixed to the body 13 and the other end is disposed on the adjusting screw 7 disposed inside the adjusting nut 6.

[0021] like Figure 1 As shown, fixed shaft A 2 and fixed shaft B 9 are set on the body 13 and respectively sleeved on the film-pulling fixed gear 3 and the film-pulling movable gear bracket 8. The adjusting bolt 7 can adjust the meshing force of the film-pulling fixed gear 3 and the film-pulling movable gear 4, thereby determining the pulling force of the film 15.

[0022] like Figure 2 As shown, the synchronous electric control device includes a main control board 11 and a speed regulation module 16, a film stretching motor 10, and a feeding motor 12, which are electrically connected to the main control board 11 respectively.

[0023] The speed control module 16 is used to adjust the speed of the film pulling motor 10. The speed of the film pulling motor 10 is set to meet the condition that the length of the film 15 pulled by the feeding motor 12 and the film pulling motor 10 is greater than the length of the material belt 14 that moves forward under the same working time.

[0024] The main control board 11 synchronously controls the start and stop of the feeding motor 12 and the film stretching motor 10. That is, when the feeding motor 12 rotates, the film stretching motor 10 also rotates at the same time, and when the feeding motor 12 stops rotating, the film stretching motor 10 also stops rotating at the same time.

[0025] Based on the specific condition that the length of the film 15 pulled by the feeding motor 12 and the film pulling motor 10 is greater than the forward movement length of the belt 14 under the same working time, that is, the forward movement speed of the belt 14 per unit time is less than the backward movement speed of the film 15, this situation will cause the belt 14 to generate a certain tension, and at the same time, the excess film 15 will be released through the mutual rotation of the film pulling fixed gear 3 and the film pulling movable gear 4, so that the film 15 maintains a certain tension.

[0026] This embodiment also provides a feeder, which includes any of the feeder synchronous film stretching structures described above.

[0027] It should be noted that feeder technology is a relatively mature technology in the prior art. This solution makes further optimizations and improvements to the control mode and film pulling mechanism of the film pulling motor 10 and the feeding motor 12. The structure of the other parts is relatively easy for those skilled in the art to understand from the prior art, so this solution will not elaborate on the other structures.
