Description

A kind of sheeting clamping device

Technical field

The utility model relates to sheeting processing technique field, especially a kind of sheeting clamping device.

Background technique

Sheeting is processed into weblike material by winding, common are hygienic paper ball.Hygienic paper ball is in cut paper machine-cut It is the toilet roll of strip before cutting.Hygienic paper ball is often easy to be loose during packaging, transport etc., needs the health to strip The paper of paper roll is fixed, and so that it will not scatter.Common pneumatic, hydraulic, electric drive as clamping power device due to It is larger to control difficulty, it is inconvenient to use.

Utility model content

The utility model can solve above-mentioned technical problem.The utility model is provided using a kind of simple fine sheet feed collet Tight device.

To achieve the goals above, the utility model adopts the following technical solution：

The sheeting clamping device includes frame, telescopic device, clamp arm, upper shaft, lower rotary shaft, positive magnet, cathode Magnet, upper shaft pass through clamp arm, and the inner wall of both ends and frame connects, and the upper end of clamp arm is fixedly connected with positive magnet, lower end and It is rotatablely connected by the movable end of lower rotary shaft and telescopic device, the fixing end of cathode magnet telescopic device is all fixed on the interior of frame Portion, when telescopic device pushes out, positive magnet and cathode magnet midfeather a distance, telescopic device thrust are cancelled When, positive magnet and cathode magnet mutually close to.

Preferably, it disconnects and is connected by nut in the middle part of the movable end of the telescopic device, it is adjustable by rotating nut The distance between movable end and fixing end.

The sheeting clamping device of the utility model is by magnet suction as clamping due to the above structure, Power, compared to pneumatic, hydraulic, electric drive is used, as the device for clamping power, more energy efficient, structure and control principle are all simpler Single, debugging is more convenient, saves the time, and clamping effect is more preferable.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

As shown in Figure 1, the sheeting clamping device of the utility model embodiment includes frame 41, telescopic device 42, folder Arm 43, upper shaft 44, lower rotary shaft 45, positive magnet 46, cathode magnet 47, upper shaft 44 pass through clamp arm 43, both ends and frame 41 Inner wall connection, the upper end of clamp arm 43 is fixedly connected with positive magnet 46, lower end with pass through lower rotary shaft 45 and telescopic device 42 Movable end rotation connection, the fixing end of 47 telescopic device 42 of cathode magnet is all fixed on the inside of frame 41, in telescopic device 42 When pushing out, positive magnet 46 and 47 midfeather a distance of cathode magnet, when 42 thrust of telescopic device is cancelled, Positive magnet 46 and cathode magnet 47 mutually close to.

The sheeting clamping device working principle of the utility model embodiment is：As shown in Figure 2-5, when strip toilet paper Volume under conveyor belt effect, be sent to it is preceding cross at cardboard 2 and the rear intermediate space for crossing cardboard 3, that is, positive magnet 46 with bear The top of pole magnet 47, due to strip toilet roll be it is soft, under belt squeeze, strip toilet roll has sub-fraction Positive magnet 46 is fallen into among cathode magnet 47, at this moment telescopic device 42 is no longer contributed, and allows positive magnet 46 and cathode magnet 47 under heteropolar interattraction, and several layers of in composite wafer material are clamped together.Telescopic device 42 can be by using oil The components such as cylinder, cylinder or motor achieve the purpose that flexible.

Paper receives extruding and can be deformed, to generate the tension opposite with clamping force.The size and paper of tension are become How much shape is positively correlated, and paper is extruded more severe, and sealing tension is bigger, seals easier scatter.The utility model is real Apply the cathode magnet 47 of example be it is fixed, positive magnet 46 presses paper towards fixed strong magnets, since paper is free end, by force When power magnet presses, the deformation being subject to simultaneously towards intermediate pressing by deformation ratio two-stage magnet is few, therefore seals warp tension ratio two-stage magnetic Iron is simultaneously towards the small of centre pressing.So the tension that the clamping device of the utility model embodiment generates paper is smaller, sealing Securely, it is not easy to scatter.

In order to adapt to more and thickness material, disconnects in the middle part of the movable end of telescopic device 42 and connected by nut 48 It connects, by the distance between 48 adjustable end of rotating nut and fixing end, i.e. 42 movable part of telescopic device is two sections, outside It is all threadedly coupled with nut 48 between one section of one section of face and the inside, thus adjusts the distances of two section movable parts, adjust indirectly Save positive the distance between magnet 46 and cathode magnet 47.

The sheeting clamping device of the utility model by magnet suction as clamp power, compared to using pneumatically, Hydraulic, electric drive is as the device for clamping power, and more energy efficient, structure and control principle are all simpler, debugs more convenient, saving Time, clamping effect are more preferable.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported Used in other related technical areas, it is also included in the patent protection scope of the utility model.
