The present invention relates to a kind of paper tube process equipment, the paper tube cutting machine detent mechanism that especially a kind of diameter is adjustable.
Background technology
Paper tube cutting machine is equipment conventional in paper tube process, and it is for being processed into product Len req by paper tube.Paper tube cutting machine of the prior art, it often adopts fixing registration roller to position paper tube, and for the paper tube that diameter differs, it need be replaced by the mould preparing many different-diameters, with the paper web for each diameter.Above-mentioned processing mode, it not only needs cost great amount of cost to prepare for mould, and simultaneously displacement work before processing also causes its production efficiency low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of detent mechanism of paper tube cutting machine, and it can regulate according to the diameter of paper tube, to adapt to the paper tube of each diameter.
For solving the problems of the technologies described above, the present invention relates to the paper tube cutting machine detent mechanism that a kind of diameter is adjustable, wherein, paper tube cutting machine comprises frame, frame is provided with adjustable registration roller and multiple cutting blade, cutting blade is all perpendicular to the axis direction of adjustable registration roller; Described adjustable registration roller is by breast roll, and the multiple arcwall face blocks being arranged on breast roll surrounding are formed, multiple central axis of arcwall face block and the dead in line of breast roll, and its arcwall face is all on the side end face of same cylinder; Described arcwall face block is connected by telescoping rod with between breast roll.
As a modification of the present invention, the length of multiple arcwall face block is all slightly larger than breast roll, and each arcwall face block is equal with the telescoping rod quantity connected between breast roll, and its being axially uniformly distributed at breast roll; Different arcwall face block and the telescoping rod be connected between breast roll, its mutual axis intersects each other.Adopt above-mentioned design, it can make the support force between arcwall face block and breast roll be uniformly distributed in axis and radial direction, can play good supporting role, thus improve its locating effect when making it locate paper web.
As a modification of the present invention, at least include 5 arcwall face blocks in described adjustable registration roller, its length and radian are all equal; When reaching minimum range between arcwall face block and breast roll, fit each other in the side end face of multiple arcwall face block.Adopt above-mentioned design, it can make paper web each position uniform force under the effect of multiple arcwall face block, and the machining accuracy avoiding its unbalance stress to cause is not high; Meanwhile, the side end face of multiple arcwall face block is arranged, and its support force provided can be made to reach maximum.
As a modification of the present invention, described breast roll adopts hollow-core construction, and its inside is provided with the adjustment rod member coaxial with breast roll; In described adjustment rod member, it is provided with multiple driving gear extended in adjusting rod radial direction; Described arcwall face block adopts ball screw structure with the telescoping rod be connected between breast roll, and it comprises by the screw rod fixed with arcwall face block, and is arranged on screw rod outside, and adopts the outboard nut be threaded between screw rod; Described outboard nut by extending to inner side outside breast roll, and and adopt between breast roll and be rotationally connected, outboard nut is provided with the driven gear perpendicular to screw axis at breast roll medial end, and described driven gear and driving gear are engaged with each other.Adopt above-mentioned design, it is by regulating the rotation of rod member, makes driving gear drive driven gear to rotate, thus regulates while realizing multiple arcwall face block, and then while keeping unity to arcwall face block, makes to regulate efficiency all to make moderate progress.
As a modification of the present invention, 1.2 to 1.8 times of roller radius centered by the length of described screw rod; 0.8 to 1.5 times of roller radius centered by the length of described outboard nut outside breast roll.Adopt above-mentioned design, its support force that the diameter adjustable extent of detent mechanism can be made to provide with it remains on optimum range.
As a modification of the present invention, in described outboard nut, itself and breast roll intersection location are provided with ring slider, and breast roll is provided with chute at slide block correspondence position.Adopt above-mentioned design, when it can make outboard nut rotate under driven gear drives, resistance suffered by it reduces, thus avoids it to damage in adjustment process.
As a modification of the present invention, the width of the axial cross section of described ring slider, by itself and outboard nut intersection location, increases gradually to its end.Adopt above-mentioned design, it can make ring slider embed in chute, thus outboard nut is fixed position in axis and radial direction, thus increases machining accuracy.
As a modification of the present invention, described breast roll one end is connected with the first drive motors; Described adjustment rod member is extended by breast roll two ends; Wherein, itself and breast roll drive end are connected to the second drive motors with side end, and the other end is provided with adjustment handle.Adopt above-mentioned design, it controls registration roller rotation realization by the first drive motors and cuts, and meanwhile, the diameter of the second drive motors shell to registration roller tentatively regulates, and by regulating handle to carry out precision adjustment to it, makes it can adapt to paper web diameter completely.
The paper tube cutting machine detent mechanism that the diameter of technique scheme is adjustable, it in use, paper tube is enclosed within registration roller, by regulating rod member to rotate in the second drive motors control centre roller, by engaging of driving gear and driven gear, outboard nut is rotated in chute, in axially-movable under the ball of screw rod inside outboard nut drives, thus makes it drive arcwall face block and paper web contact internal walls; Now by regulating handle to carry out accurate adjustment to it, arcwall face block is made to realize supporting and location to paper web.First drive motors controls registration roller and rotates, thus makes the cutting of cutting blade realization to paper web.
Adopt the paper tube cutting machine detent mechanism that the diameter of technique scheme is adjustable, it can according to the diameter of the diameter adjustment registration roller of paper web, thus avoid it need prepare multiple mould according to the diameter of paper web replacing, while saving production cost, also can effectively improve its operating efficiency.
