Adhesivetape box-sealing machine core cut belting
Technical field
The utility model relates to tape sealing machine, relates in particular to the pressing wheel device of Adhesivetape box-sealing machine core.
Background technology
The movement of tape sealing machine is in the tape sealing machine adhesive tape to be sealed on the top cover of packing case or the device of bottom, cuts belting and plays the effect of cutting off adhesive tape, is the important device that guarantees joint sealing quality and the normal operation of cartoning sealing machine.In the past cut belting, comprise movement side plate, rotating knife rest, an end of knife rest connects the blade installing rack, an end of knife rest connects stage clip, blade cuts off the strength of adhesive tape, from the restoring force of stage clip, the restoring force of stage clip is regulated by nut.This structure cut belting, the adjusting of stage clip is not too convenient, especially can not influence the efficient of tape sealing machine at the joint sealing scene according to actual conditions quick adjustment stage clip.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of belting of cutting of Adhesivetape box-sealing machine core easy to adjust.For this reason, the utility model is by the following technical solutions: it comprises movement side plate, rotating knife rest, one end of knife rest connects the blade installing rack, the described belting of cutting also is provided with extension spring, the other end of knife rest is connected with an end of extension spring, described movement side plate is provided with the profile of tooth gear of regulating extension spring, and the described belting of cutting is provided with the adjusting rod that cooperates with the profile of tooth gear, and the other end of described extension spring links to each other with adjusting rod.Owing to adopt the technical solution of the utility model, the utility model can very conveniently carry out extension spring apace and regulate by regulating the position of adjusting rod on the profile of tooth gear, and operation is very easy and fast, improve the efficient of tape sealing machine.
Description of drawings
Fig. 1 is the schematic diagram of embodiment provided by the utility model.
Fig. 2 is embodiment illustrated in fig. 1, after removing a side movement side plate, and the schematic diagram of another direction.
The specific embodiment
With reference to accompanying drawing.The utility model comprises movement side plate 1, rotating knife rest 2, one end of knife rest connects blade installing rack 3, the described belting of cutting also is provided with extension spring 4, the other end of knife rest is connected with an end of extension spring 4, described movement side plate is provided with the profile of tooth gear of regulating extension spring, the described belting of cutting is provided with the adjusting rod 7 that cooperates with the profile of tooth gear, and the other end of described extension spring links to each other with adjusting rod.
In the present embodiment, knife rest is provided with extension spring connecting rod 5, and is connected with extension spring by the extension spring connecting rod.
The profile of tooth gear is by its gear tooth location adjusting rod, and this profile of tooth gear can adopt the mode of offering serrate slot 6 on the movement side plate by present embodiment, processes more conveniently like this, locatees also more reliable.Certainly, the profile of tooth gear also can adopt the frame modes such as part that connect the fluted projection of profiled parts or interval on the movement side plate.
With reference to accompanying drawing, knife rest 2 has common rotary supporting shaft 9 with the preceding pinch roller frame 8 of Adhesivetape box-sealing machine core, makes that the structure of movement is more compact, and axle 9 is bearing on the side plate 1.
When packing case is pressed arrow direction shown in Figure 2, preceding pinch roller 81 on the preceding pinch roller frame is pushed up from initial bit by casing, pinch roller frame rotates before driving, preceding pinch roller abuts in tank surface, pressing compresses adhesive tape, simultaneously packing case is run into behind the knife rest 2 its jack-up, and blade installing rack 3 is rotated, and extension spring is stretched.Packing case continues motion, when packing case break away from the contacting of knife rest after, under the effect of extension spring restoring force, the knife rest backward rotation drives blade revolution on the blade installing rack with the adhesive tape cut-out, cartoning sealing machine can carry out next joint sealing work.In operation, regulate extension spring 4, only need operating personnel to make it be in positions different in the serrate slot and get final product with hand direct control adjusting rod as need, very convenient.In the drawings, drawing reference numeral 10 is the adhesive tape one-way rolling.
