DETAILED DESCRIPTION

[0035] The following will be combined with 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 are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1 As shown, the cutting control device of the wrapping film of the fully automatic baling machine includes a mounting frame 1; a resistance wire 5, one end of which is connected to the mounting frame 1 through a first insulator 61; an elastic member 7, which is used to provide a force for changing the position of the other end of the resistance wire 5; a switch 11, which directly or indirectly drives the switch 11 to operate after the position of the other end of the resistance wire 5 changes; and a controller 8, which is connected to the switch 11 and the resistance wire 5.

[0038] In this embodiment, in order to solve the problem of contamination of high white fiber or sanitary napkin by shedding of braided film in the prior art, a cutting control device for the surrounding film of the fully automatic baling machine is provided, comprising a mounting frame 1, wherein the mounting frame 1 has a suspension portion 2 and a fixing portion 3; now the resistance wire 5 and the elastic member 7 are connected in sequence, wherein one end of the resistance wire 5 is connected to the fixing portion 3 through a first insulator 61, the elastic member 7 is a tension spring, the controller 8, the connecting line 9 and the resistance wire 5 form a closed electrical circuit, and when the controller 8 is loaded with voltage, there is a When current passes through, heat is generated, causing the resistance wire 5 to heat up. The woven bag or woven film close to the resistance wire 5 is thermally cut along the resistance wire 5, and the cut edges of the woven bag or woven film are hot-melt and then reconnected. This thermal cutting avoids the burrs caused by knife cutting, making the incision neat and firm, and avoiding loose cut edges; the resistance wire 5 softens after heating, and after exceeding a certain temperature, the restoring force of the elastic member 7 overcomes the resistance of the resistance wire 5, causing the resistance wire 5 to extend under the restoring force of the elastic member 7, always keeping the resistance wire 5 taut and straight, ensuring the smoothness and straightness of the cut edges.

[0039] like Figure 1 As shown, the switch 11 is a proximity switch and further includes a connecting member 4, one end of which is connected to the other end of the resistance wire 5 through a second insulating member 62. When the position of the other end of the resistance wire 5 changes, the connecting member 4 is driven to move; and a swinging member 12, which is arranged on the mounting frame 1. When the connecting member 4 moves, the swinging member 12 is driven to swing. After the swinging member 12 swings, one end thereof approaches or moves away from the switch 11.

[0040] In this embodiment, in order to achieve the purpose of controlled cutting and overcome the problem that the overheating of the resistance wire 5 causes the cut end of the woven bag or woven membrane to be carbonized, a connecting member 4 is connected between the resistance wire 5 and the elastic member 7. The connecting member 4 is a flexible member such as a steel wire rope. One end of the resistance wire 5 is connected to the fixed part 3 through the first insulator 61, and the other end is connected to the connecting member 4 through the second insulator 62, wherein the connecting member 4 is movably hung on the suspension part 2, and the swinging member 12 is connected to the connecting member 4. When the resistance wire 5 is overheated, that is, the temperature of the resistance wire 5 is greater than 500°C, the resistance wire 5 elongates under the action of the restoring force of the elastic member 7, causing the connecting member 4 to move, and then the connecting member 4 drives the swinging member 12 to rotate around the hinge point between it and the mounting frame 1, so that the swinging member 12 disengages from the switch 11 after rotation. The distance between the connecting member 4 and the hinge point between the swinging member 12 and the mounting frame 1 is smaller than the distance between the switch 11 and the hinge point between the swinging member 12 and the mounting frame 1. That is, the swinging member 12 is a lever, so that the movement of the connecting member 4 is amplified by the swinging member 12 and then transmitted to the switch 11, and the switch 11 transmits the signal to the controller 8. The controller 8 includes a control cabinet and an automatic voltage regulator. The switch 11 transmits the signal to the control cabinet, and the control cabinet controls the automatic voltage regulator to automatically reduce the voltage to reduce the power of the resistance wire 5, so that the temperature of the resistance wire 5 is reduced to 400℃~500℃, avoiding the woven bag or woven membrane from being burned and carbonized at a high temperature greater than 500℃, thereby affecting the toughness and quality of the woven bag; the distance a between the connection point of the swinging member 12 and the connecting member 4 and the hinge point of the swinging member 12 and the mounting frame 1 is less than the distance b from the hinge point of the swinging member 12 and the mounting frame 1 to the free end of the swinging member (switch 11), and a:b is less than 1:2, so that the movement distance of the connecting member 4 is amplified by the free end of the swinging member 12, so that the opening and closing of the switch 11 have obvious changes, thereby realizing automatic disconnection.

[0041] like Figure 1 As shown, the distance between the hinge point between the swing member 12 and the mounting bracket 1 and the connecting member 4 is smaller than the distance between the swing member 12 and the switch 11 .

[0042] In this embodiment, when no power is applied, the restoring force of the elastic member 7 is less than the tension of the resistance wire 5, so that the connection point between the swing member 12 and the connecting member 4 is biased toward the resistance wire 5, and the switch 11 is in the open state; then after power is applied, the resistance wire 5 is heated to 400℃~500℃, and the tension of the resistance wire 5 is equal to the restoring force of the elastic member 7, so that the swing member 12 is in a vertical state, and the switch 11 is in the closed state; when the temperature of the resistance wire 5 is greater than 500℃, the tension of the resistance wire 5 is less than the restoring force of the elastic member 7, so that the connection point between the swing member 12 and the connecting member 4 is biased toward the elastic member 7, and the heating state of the resistance wire 5 can be observed by the deflection direction of the swing member 12, which is simple, direct and fast, and then the voltage at both ends of the resistance wire 5 can be quickly adjusted according to the deflection direction of the swing member 12, and the operation is simple.

[0043] like Figure 1 As shown, it also includes a mutual inductance detector 13, which includes a mutual inductance coil 14, which is mounted outside any of the connecting lines 9; and a signal converter 15, which is connected to the mutual inductance coil 14 and is used to detect the current of the resistance wire 5 and transmit the signal to the controller 8.

[0044] In this embodiment, a connecting wire 9 between the resistance wire 5 and the controller 8 passes through a mutual inductance coil 14. The mutual inductance coil 14 is used to monitor the current passing through the resistance wire 5, calculate the power of the resistance wire 5 according to the set current value, determine whether it has reached the heating temperature of 400°C to 500°C, and transmit the signal to the controller 8 through the signal converter 15. The controller 8 adjusts the voltage of the resistance wire 5 to change the current passing through the resistance wire 5.

[0045] like Figure 1 As shown, the resistance wire 5 is a nickel-chromium resistance wire with a diameter of 0.8 mm, and the voltage of the controller 8 is below 48V.

[0046] In this embodiment, the 0.8mm nickel-chromium resistance wire is resistant to high temperatures and not easy to break, so that the cutting opening of the woven bag or woven membrane is 0.8mm, avoiding the waste caused by cutting the woven bag or woven membrane, greatly saving production costs; and the voltage is controlled below 48V, further saving production costs.

[0047] like Figure 1 As shown, the heating temperature of the resistance wire 5 during operation is 400° C. to 500° C.

[0048] In this embodiment, the heating temperature of the resistance wire 5 during operation is 400°C to 500°C, so that the woven bag or woven membrane is quickly disconnected and then welded under this temperature condition, avoiding the phenomenon of wire drawing at the incision caused by the temperature being lower than 400°C, which affects the quality of the incision, or the wire drawing and adhesion contaminates high-white fibers or sanitary napkins; at the same time, avoiding the temperature being higher than 500°C, which causes the woven membrane near the cut to be carbonized or burned, affecting the toughness, quality and service life of the woven bag or woven membrane.

[0049] like Figure 1 As shown, the signal converter 15 is connected to the controller 8 .

[0050] In this embodiment, the signal converter 15 is connected to the control cabinet of the controller 8. After the signal converter 15 transmits the signal to the control cabinet, the control cabinet controls the automatic voltage regulator to adjust the voltage.

[0051] Example 2

[0052] like Figures 1 and 2As shown, on the basis of having all the technical features of Example 1, it also includes a secondary amplification mechanism, the secondary amplification mechanism includes a rotating shaft 16, which is rotatably set on the mounting frame 1, and the rotating shaft 16 is sequentially provided with a first gear 17 and a second gear 18; a first rack 19, which is set on the connecting member 4, and the first rack 19 is engaged with the first gear 17; and a second rack 20, which is set on the swinging member 12, parallel to the first rack 19, and the second rack 20 is engaged with the second gear 18.

[0053] In this embodiment, after the connecting member 4 moves, it drives the first rack 19 to move, and the movement of the first rack 19 drives the first gear 17 to rotate. The rotation of the first gear 17 is transmitted to the second gear 18 through the rotating shaft 16, so that the second gear 18 drives the second rack 19 to move, and the second rack 19 drives the swinging member 12 to swing, converting the movement of the connecting member 4 into the swinging of the swinging member 12, thereby realizing the opening and closing of the switch 11.

[0054] like Figures 1 and 2 As shown, the first gear 17 and the second gear 18 have the same number of teeth, and the outer diameter of the second gear 18 is larger than the outer diameter of the first gear 17 .

[0055] In this embodiment, the outer diameter of the second gear 18 is larger than the outer diameter of the first gear 17, so that the path of the first rack 19 driving the first gear 18 to rotate is smaller than the path of the second gear 18 driving the second rack 20 to rotate, and the movement of the connecting member 4 is amplified, so that the swinging member 12 swings obviously, and the switch 11 is accurately opened and closed; it avoids the situation where the moving member 4 moves too small a distance, so that the swinging angle of the swinging member 12 is not obvious, and the switch 11 cannot be opened and closed.

[0056] like Figures 1 and 2 As shown, the connecting member 4 is a flexible member.

[0057] In this embodiment, the connecting member 4 is a flexible member with toughness, such as a steel wire rope, to prevent the connecting member 4 from colliding with the mounting frame 1 during the sliding process and affecting the service life of the swing member 12.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
