Abstract
The utility model discloses a paper tube forming core rod comprising a core rod body that consists of a forming section and a guide section, wherein the guide section is rotatably connected on the forming section and provided with an inner cavity; the inner cavity is connected with a spindle capable of axially sliding; one end of the spindle is rotatably connected with an anvil wheel outside the inner cavity, and the other end of the spindle is connected with a return spring arranged in the inner cavity; the inner cavity is fixedly provided with a connecting sleeve that is rotatably connected on the forming section; and one end of the return spring is connected on the connecting sleeve, and the other end of the return spring is connected with the spindle. The advantage of the core rod with the structure lies in simple structure. In use, the core rod has the benefit of being not easy to damage a cutoff tool and a paper tube or cause wrinkle or damage to the inner wall of the paper tube, and being beneficial to improvement of product quality and reduction of manufacturing cost.
Description
Technical field
The utility model relates to a kind of paper tube moulding plug.
Background technology
Paper tube is widely used in the industrial production of all trades and professions, and industries such as for example papermaking, weaving, chemical fibre are the underlying carriers that paper roll, cloth, plastic sheeting, yarn etc. are reeled or twined.At present, the paper tube moulding plug that paper tube manufacturing machine on the market adopts is a monoblock type, and paper tape is after being shaped to paper tube on the plug, and paper tube slides to the end of plug along plug, when the length that skids off plug when paper tube reached and sets size, cutoff tool matched with the distal portion of plug paper tube is downcut; Along with paper tape continuously shaped and cutoff tool on plug constantly cuts off, the paper tube that adheres to specification is just produced endlessly.Mainly there is following defective in the plug of said structure: the one, in the sliding process after the paper tube moulding, and still produce higher the relatively rotating of speed between the plug, under the effect of radial frictional force, the inwall of paper tube is wrinkling or damaged easily, has a strong impact on the quality of paper tube; The 2nd, in the paper tube cutting-off process, cutoff tool needs and the same moved further of paper tube, because plug does not move, just produces contacted relatively moving between cutoff tool and the plug, therefore is easy to damage cutoff tool and damages paper tube.
Summary of the invention
The technical problem that the utility model at first will solve is at above-mentioned first defective, and a kind of paper tube moulding plug of causing the paper tube inwall wrinkling or damaged of being difficult for is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of paper tube moulding plug with following structure, comprises the plug body, and its design feature is that the plug body is made of profiled section and guide section, and guide section is rotatably connected on the profiled section.
Because guide section is rotatably connected on the profiled section, after paper tube moved on the guide section, guide section can rotate with paper tube, did not produce relative rotation between the surface of paper tube inwall and guide section, do not produce circumferential frictional force, therefore be difficult for causing the inwall of paper tube wrinkling or damaged.
In order to solve second defective described in the background technology, done following improvement on the basis of technique scheme: described guide section is provided with inner chamber, be connected with mandrel in axial sliding in the inner chamber, one end of mandrel is rotatably connected to the anvil wheel that is positioned at the inner chamber outside, and the mandrel other end is connected with back-moving spring in being located at inner chamber.
As between a kind of guide section and the profiled section and the concrete connected mode of back-moving spring in inner chamber, be fixed with adapter sleeve in the described inner chamber, adapter sleeve is rotatably connected on the profiled section, and back-moving spring one end is connected on the adapter sleeve, and the back-moving spring other end is connected with mandrel.
In the improved technical scheme, because anvil wheel is rotatably connected in axial sliding on the mandrel, cutoff tool moves in the process of cutting, can move with cutoff tool, and the two does not produce axial relative motion, therefore, is difficult for causing the damage of cutoff tool and paper tube.
Advantage of the present utility model is: simple in structure, can not bring cutoff tool and paper tube fragile and be difficult for the beneficial effect that causes the paper tube inwall wrinkling or damaged during use, not only improved product quality and reduced the replacing number of times of cutoff tool, and improved production efficiency accordingly and reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Paper tube moulding plug as shown in Figure 1 comprises plug body 1, and plug body 1 is made of profiled section 11 and guide section 12.Guide section 12 is provided with inner chamber 13, one end of inner chamber 13 is installed with adapter sleeve 5, the other end insert sliding sleeve 6 of inner chamber 13, adapter sleeve 5 is rotatably connected on the profiled section 11 by bearing 7, the inner chamber outer end of adapter sleeve 5 also is bolted with the bearing (ball) cover 8 that is used for bearing 7 axial location, and bearing (ball) cover 8 is provided with the jack 9 that inserts spanner when being used for dismounting; Slidely connect mandrel 2 in the sliding sleeve 6, the overhanging end of mandrel 2 is rotatably connected to anvil wheel 3, also is provided with the back-moving spring 4 between adapter sleeve 5 and sliding sleeve 6 in the inner chamber 13, and back-moving spring 4 one ends are connected with adapter sleeve 5, and back-moving spring 4 other ends are connected with mandrel 2.The effect of back-moving spring 4 is: after one time cutting-off process is finished, anvil wheel 3 is resetted.During use, only need the plug card of this structure to be pressed on the pedestal 14 of paper tube shaper and get final product by gland 10.
