Abstract

The utility model relates to an automatic rise-and-fall rolling wheel mechanism for a PVC thin slice calender. A positive L type calender and an inverse L type calender with different structures are required to be prepared for the prior art to meet the production of a hard thin slice and a soft thin slice. The utility model has the technical proposal of improving the rolling wheel structure of the calender, to ensure front row of single rolling wheel automatically rise and fall. The automatic rise-and-fall rolling wheel mechanism of the PVC thin slice calendar consisting of two rows of rolling wheels comprises a rolling wheel, a lower limit switch, a bearing plate, a ladder type threaded rod, a rise-and-fall machine, a connecting beam, a drive motor, a coupling, a sliding block, a bearing group, a slide rail, a rack and a high limit switch. The utility model has the advantages that the improvement of the rolling wheel structure ensures the rolling wheel rise and fall automatically, one calender both can be used as the positive L type rolling wheel structure calendar and can be used as the inverse L type rolling wheel structure calendar, to become one machine with dual purposes that not only the equipment investment can be reduced, but also the energy sources consumption can be saved.

Description

But the running roller mechanism of the PVC thin slice calender of automatic lifting

Technical field

The utility model relates to a kind of running roller structure of plastic tab calender, particularly relates to a kind of running roller structure of liftable PVC thin slice calender.

Background technology

At present, the PVC sheet product on the market mainly contains two big classes: 1). hard PVC sheet product, 2). the flexible PVC sheet product.Different product needed is used the different thin slice calender of running roller type of array, as: 1). the calendar rolls wheel construction that the hard sheet product requirement uses is the calender that the single running roller in vertical two row running rollers is arranged at end row just L shaped running roller arranged side by side; 2). the calendar rolls wheel construction that soft sheet product requires to use is that single running roller in vertical two row running rollers is at the top row calender that falls L shaped arrangement arranged side by side.The different main causes of arranging of the running roller of calender are: 1). in the composition of raw material of flexible PVC sheet product, contain volatile plasticizer, can only select feeding mouth calender up, promptly running roller is down the calender of L shaped arrangement.So in process of production, plasticizer is volatilization upwards, and soft sheet product moves down, and product can not be subjected to the pollution of plasticizer; 2). plasticizer-containing not in the raw material of hard sheet product, analyze in theory, just L shaped and fall L shaped calender and all can use.But according to the industry experience, production technology and operating habit, hard sheet product are all selected just L shaped calender production.So, produce product desirable, that ensure the quality of products, the calender that be equipped with two cover different structures satisfies the production of hard sheet and soft thin slice.

Summary of the invention

In order to overcome the deficiencies in the prior art, whether imagination can make improvements by the running roller structure to PVC thin slice calender, reach same equipment and both can produce the hard sheet product, can produce soft sheet product again, be the purpose of this utility model place but a kind of running roller structure of PVC thin slice calender of automatic lifting is provided.

The difference of just L shaped calender and inverted L shape calender is in the running roller structure that the running roller position height of standing out is different.The technical solution of the utility model is to improve the running roller structure of calender, and the single running roller in prostatitis can be raise and reduce automatically, according to production requirement, is arranged in just L shaped or falls L shaped calendar rolls wheel construction.The utility model is to come the specific implementation technical scheme by following technical measures: but a kind of running roller mechanism of PVC thin slice calender of the automatic lifting of forming by vertical two row running rollers, it comprises: running roller 1, supporting plate are connected the screw 2 of usefulness with bearing group, low limit switch 3, supporting plate 4, trapezoidal screw 5, lifter 6, the attachment screw 7 of tie-beam and base, tie-beam 8, cased muff coupling 9, drive motors 10, kinematic link 11, base 12, the attachment screw 13 of slide block and bearing group, slide block 14, bearing group 15, slide rail hold-down screw 16, slide rail 17, frame 18, high limit switch 19.Wherein: adorn two bearing group 15 on the axial two ends of running roller 1, bearing group 15 and width are that the slide block 14 usefulness attachment screws 13 of 50mm-150mm are fixed together, length is that the slide rail 17 of 350mm-3500mm is slidingly matched with slide block 14, and slide rail 17 usefulness screws 16 are fixed on the frame 18; The bottom of bearing group 15 is connected with supporting plate 4 usefulness screws 2, adopt the 45# forged steel and through Luo line scope heat treatment process, trapezoidal be Tr40 * 7-Tr90 * 16, the spiro rod length scope is that the two ends of the trapezoidal screw 5 of 300mm-3000mm connect supporting plate 4 and lifter 6 respectively, it is 300Kg-3000Kg that lifter 6 is selected the lifting weight scope for use, and is screwed on tie-beam 8; The tie-beam 8 usefulness screws 7 that hot rolling I-shaped steel is made are fixed on the base 12, drive motors 10 is the motor of two shaft types, be screwed on tie-beam 8, two spindle noses are connected with the cased muff coupling 9 at two ends respectively, and shaft coupling 9 links together with kinematic link 11; High limit switch 19 and low limit switch 3 are fixed on the frame 18 by screw respectively, and its particular location is determined by the lifting of debugging running roller.More than each assembly be the metal material manufacturing, and for realizing the assembling of modular, and convenient later maintenance, it is fixing all to adopt high-strength screw to connect between each assembly.

When the production kind of conversion PVC thin slice needs the running roller structure of lifting calender, as long as start drive motors 10, drive running rollers 1 by the kinematic link 11 on both sides, firm domestic animal shaft coupling 9, lifter 6 and trapezoidal screw 5 and upwards run into high limit switch 19 or run into low limit switch 3 downwards along two wood side-guides 17.To meet the needs of production.

It is 280mm-1630mm that the utility model is suitable for the width of producing soft thin slice of PVC and hard sheet; Thickness is 0.1mm-2mm.The diameter of the running roller 1 that is suitable for is φ 100mm-φ 610mm; The running roller width is 350mm-2030mm.

Good effect of the present utility model is the improvement by the pair roller wheel construction, increases elevating mechanism, guide frame, position limiting structure, thereby running roller lifting automatically.The running roller structure calender that makes a calender both can make positive L type uses, and the calender that also can make inverted L shape running roller structure uses, and accomplishes dual-use, both can reduce equipment investment, energy savings consumption again.
