[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0020] The utility model provides a kind of bag heat sealing device, as shown in Figures 1-4 The utility model provides a kind of bag heat sealing device, as shown in

[0021] In order to solve the problem that manpower is arranged, and the bag opening is pinched together by hand, and finally sent into the sealing machine to seal, the operation is more laborious, and the sealing efficiency is low, the utility model is provided with mounting plate 4 on both sides of support 1, and two mounting plates 4 are oppositely arranged, electric cylinder 5 is arranged on mounting plate 4, and the end of the telescopic section of electric cylinder 5 is fixedly installed with push plate 6, and two push plates 6 are cooperatively arranged.

[0022] The utility model is provided with telescopic rod 7 on the top of one side of two push plates 6, one end of telescopic rod 7 is fixedly installed with clamping plate 8, two clamping plates 8 are cooperatively arranged, and spring 9 is arranged on the two sides of telescopic rod 7 on push plate 6. In working, the bag 11 filled with material is placed on the center line position of conveying belt 2, conveying belt 2 conveys bag 11 to the position of sealing machine 3, when bag 11 is conveyed to the position of push plate 6, two electric cylinders 5 are started, two push plates 6 are driven to approach each other, and bag 11 can be pushed to the center line position of conveying belt 2. When two push plates 6 approach each other, telescopic rod 7 and spring 9 drive two clamping plates 8 to approach each other and clamp the bag opening of bag 11. Since the distance between two clamping plates 8 is closer, two clamping plates 8 clamp the bag opening of bag 11 first, and then push plate 6 pushes bag 11 to approach the center line. In this way, the situation that bag 11 is pushed down by push plate 6 and material is spilled can be avoided. When two clamping plates 8 approach each other and clamp the bag opening, the air in bag 11 can be discharged, so that the bag opening is adhered together. At this time, bag 11 with adhered bag opening is conveyed to the position of sealing machine 3, the bag opening enters sealing machine 3, and heat sealing is facilitated, which saves time and effort and improves sealing efficiency.

[0023] Two push plates 6 are provided with stop rods 10, and the two stop rods 10 are arranged opposite to each other. When the bag 11 is separated from the clamping plate 8 and does not enter the sealing machine 3, the stop rod 10 can be blocked on both sides of the bag 11, which can prevent the bag 11 from falling.

[0024] Further, when the first bag 11 is not sealed and the second bag 11 runs faster and enters the sealing machine 3 in advance, if left unchecked, the second bag 11 may affect the normal sealing operation of the first bag 11. At this time, the second bag 11 can be stopped by clamping the second bag 11 with the two push plates 6, so as to ensure the smooth operation of the heat sealing work.

[0025] Further, the electric cylinder 5 can drive the push plate 6 to move back and forth. Because of the existence of the spring 9, the two clamping plates 8 can always clamp the bag opening of the bag 11, so as to arrange the materials in the bag 11, make the materials in the bag more flat, and reduce the probability of the bag 11 falling.

[0026] The two side walls of the bracket 1 close to each other are provided with support plates 12, and the two support plates 12 are movably attached to the conveying belt 2. The support plate 12 can support the conveying belt 2, reduce the stress of the conveying belt 2, protect the conveying belt 2, and be conducive to transporting the bag.
