When the roller extrudees the sizing material, partial sizing material is easy to follow roller landing to the both ends of roller, and the roller can't extrude the sizing material that drops to both sides, and then needs the staff to repeatedly place the sizing material and extrude between two rollers, and it is lower to have increased staff's work load and production efficiency.

In the conventional technical scheme, a pair of limiting baffles are generally arranged at positions close to two ends of a roller, so that rubber materials are prevented from sliding to the two ends of the roller, but the height position of the limiting baffles needs to be manually adjusted after the roller distance is adjusted, the horizontal position of the limiting baffles needs to be manually adjusted after the width of the required materials is changed, the baffles can be cut and rubbed with the working surface of the roller in the process of adjusting the horizontal position, the quality of the produced rubber materials is further influenced, the service life of equipment is prolonged, and meanwhile, the manual adjustment is low in efficiency, complicated in operation and potential safety hazards of scalding and crushing. Although some technologies can automatically adjust horizontal position, the height position still relies on the manpower to the laminating state of spacing baffle and roller working face is extremely poor among the prior art, and the baffle can wear away the roller if too tight, and the spacing effect of baffle is difficult to guarantee again if too loose.

Therefore, smelt gluey equipment technical field, need urgently need one kind and can automize and adjust spacing baffle horizontal position and high position, the adjustment process does not consume the roller, baffle and the good mill touching formula spacing system of roller working face laminating state.

Detailed Description

Referring to fig. 1 to 3, the open mill touch type limiting system comprises a base 1 and two rollers 2 which are arranged on the base 1 in parallel and are respectively hinged with the base 1, wherein support frames 3 are symmetrically arranged on the base 1 and at two ends of the rollers 2, slide rods 4 are axially and fixedly connected between the symmetrical support frames 3 and the parallel rollers 2, and the slide rods 4 are positioned above the rollers 2 and are equidistant from the two rollers 2; a pair of sliding blocks 5 are symmetrically matched on the sliding rod 4, opposite side surfaces of opposite surfaces of each sliding block 5 are fixedly connected with the output end of a first pressure cylinder 6, and the first pressure cylinder 6 is fixedly connected on the support frame 3 in the horizontal direction; the vertical second pressure cylinder 8 that sets up in 5 bottom surfaces of slider, the vertical rigid coupling stop gear of mounting panel 1 is passed through to the 8 outputs of second pressure cylinder, stop gear includes the axial limit baffle of working face perpendicular to roller 2, limit baffle is big-end-up, and its lower part is the curved surface with 2 operation face looks adaptations of roller.

It should be noted that the working principle of the present invention is: the two rollers 2 rotate oppositely to roll the rubber and plastic, but when the thickness of the required product changes, the roller distance is firstly adjusted, and then the height position of the limit baffle is adjusted by the second pressure cylinder 8; when the width of a required product changes, the horizontal position of the limiting baffle is automatically adjusted through the first pressure cylinder 6, the height position of the limiting baffle is adjusted through the second pressure cylinder 8, when the horizontal position is adjusted, the second pressure cylinder 8 firstly lifts the limiting baffle to a certain height, and the horizontal position is adjusted in place and then is restored to the height position, so that the full-automatic operation is realized, the abrasion of the roller 2 caused by scraping and rubbing during the adjusting process is avoided, and the safety risk of scalding and crushing of operators is avoided.

It can be understood that the roller spacing adjustment of the roller 2 is the necessary prior art in the operation of the existing open mill, the pressure cylinder can be a hydraulic cylinder or a pneumatic cylinder, the side surface of the limit baffle close to the working surface of the roller 2 is matched with the working surface of the roller 2 in shape, the limit baffle is a smoothly changing curved surface, the left side surface and the right side surface are converged into a tip end in the middle, and the tip end is positioned between the two rollers. These are conventional techniques well known to those skilled in the art and are not the point of improvement in this scheme and will not be described further herein.

Further, the limiting baffle comprises an inner baffle 11 fixedly connected with the mounting plate 1, the two side faces, close to the operation face of the roller 2, of the inner baffle 11 are symmetrically sleeved with outer baffles 12, and the lower ends of the two symmetrical outer baffles 12 are hinged with the lower end of the inner baffle 11; still be equipped with micromotor 14 through fixed plate 13 on the mounting panel 1, rigid coupling turbine 17 behind baffle 11 in parallel roller 2 axial of output of micromotor 14, the vertical penetration, turbine 17 is connected with the meshing in the middle part of the 2 axial worms of perpendicular roller 18, 18 both ends of worm symmetry are equipped with sleeve 19 and form the meshing respectively and connect, the screw thread that two sleeves 19 of sleeve 19 one end was equipped with internal thread and symmetry is revolved to opposite, the sleeve 19 other end and constitute the sphere pair with outer baffle 12 articulated push rod 20. It can be understood that the inner baffle 11 and the outer baffle 12 are tightly attached to each other perpendicular to the axial side of the roller 2, so that the melted rubber material cannot enter between the inner baffle and the outer baffle. When the roller spacing is adjusted to be large or the height of the limit baffle is raised, the micro motor 14 drives the worm 18 to rotate through the turbine 17, and the worm 18 pushes the outer baffle 12 to the working surface of the roller 2 through the sleeve 19 and the push rod 20; on the contrary, when the roller spacing is adjusted to be small or the height of the limiting baffle is reduced, the micro motor 14 drives the worm 18 to rotate reversely through the worm wheel 17, the worm 18 pulls the outer baffle 12 away from the working surface of the roller 2 through the sleeve 19 and the push rod 20, namely, the transmission assemblies can ensure that the baffle is in good fit with the working surface of the roller. Obviously, the rotation of the micro motor 14 and the stop of the outer baffle 12 after being in place are controlled by the open mill controller, the inner core of the controller can be a single chip microcomputer, a PLC and the like, and the receptor in the in-place state can be a proximity sensor, a piezoresistor and the like, which are used as conventional technologies and will not be described herein again.

Furthermore, a pulling plate 15 is arranged between the sliding block 5 and the second pressure cylinder 8, pulling rods 16 are arranged between the pulling plate 15 and the mounting plate 1 and on two sides of the second pressure cylinder 8, one end of each pulling rod 16 is vertically and fixedly connected with the mounting plate 1, and the other end of each pulling rod penetrates through the pulling plate 15 and forms sliding connection with the pulling plate. It will be appreciated that the tie rod 16 may make the connection of the limiting mechanism more secure, the tie rod 16 being slidably connected to the tie plate 15 when the second cylinder 8 raises and lowers the limiting mechanism.
