Description

Technical Field

The invention relates to the field of processing of tubular materials, in particular to a full-automatic continuous sleeving and shrinking machine which needs to spray liquid on the inner wall of a tubular material.

Background

Tubular packaging materials, especially tubular films, are used for hermetically sealing and preserving filling materials from air, for example, gunpowder filling requires packing with gunpowder packaging materials, chemical fertilizers buried in the ground are often sealed with a cellulose having a penetrating and self-decomposing function, and casings are often used for hermetically sealing filled meat paste in the field of food processing. Before filling, the tubular packaging material needs to be shrunk.

Some tubular packaging materials require a liquid spray on the inner wall, such as some non-edible peeled casings, and after the sausage is filled, cooked and formed, the casings need to be peeled off in time, and grease which is easy to peel off needs to be sprayed on the inner wall of the casings in advance. There are also edible collagen casings, which need to avoid separation of the casing from the meat, and which require the inner wall of the casing to be coated with a starchy medium which readily adheres to the meat.

The existing shrinking equipment is usually in an intermittent shrinking mode to inflate the interior of a material and synchronously spray liquid into the material. Gas injection and liquid injection are carried out into the telescopic rod by utilizing the butt joint rod or the holding rod clamp, after the telescopic rod is shrunk by one section of material, the telescopic rod is disassembled, at the moment, the butt joint rod or the holding rod clamp needs to be separated from the telescopic rod, at the moment, the internal gas injection and the liquid injection are stopped, the telescopic shrinkage is suspended, and the telescopic shrinkage can not be started until the butt joint rod or the holding rod clamp is connected with the telescopic rod again and the next material is shrunk.

Although the intermittent sleeving and shrinking machine can realize liquid spraying in the sleeving and shrinking rod, the intermittent sleeving and shrinking production efficiency is lower. And each material needs to be started for shrinkage once, so that the shrinkage effect is often influenced, and the defective rate is increased.

lower rollers

202 and 204 are folded to compress the material and are driven by the motor 206 to actively roll (rotate) so as to convey the material. The inductor obtains the material length of carrying through calculating the number of turns that the running roller rolled. The length of the material is equal to the product of the perimeter of the roller and the number of rolling turns.

Further, as shown in fig. 1 and 3a and 3b, the sleeve compressing mechanism 30 includes a housing 302, a feeding wheel set 304 at an inlet of the housing 302, and a sleeve shrinking head 306 at an outlet of the housing. The feeding wheel sets 304 are more than one set, and two sets in this embodiment. Of course, the number of feeding wheel sets 304 may also be three, four, five or other suitable sets, and is not limited herein. Each group of feeding wheel set 304 comprises two rollers which are arranged in opposite matching, a groove 308 corresponding to the size of the material is arranged on the outer circumferential surface of each roller, the feeding wheel set 304 is driven by a motor 310 to rotate actively, the roller groove 308 is attached to the material which is inflated and expanded into a cylinder shape, and the material is conveyed to the shrinking head 306 by friction force.

The pressing strips 504 are uniformly distributed around the telescopic rod 40 and are axially parallel to the telescopic rod 40. When the telescopic rod-shaped material coming out of the telescopic head 306 enters the rotary rod holding clamp 50, the pressing strips 504 are spread by the material, the rotary sleeve 502 is driven by the motor 506 to rotate actively, so that the pressing strips 504 uniformly distributed around the telescopic material are driven to rotate and slide on the surface of the material, a twist lock force is generated in the circumferential direction when the material is folded in a thread shape, and the material is more compact and is not easy to fall apart. The finished telescopic rod-shaped material is often bent into an arc shape after leaving the telescopic rod 40. By adopting the rotary rod holding clamp 50, the materials after being sleeved and contracted can be uniformly distributed towards the bending of one side due to rotation, so that the finished product can keep straight.

Further, as shown in fig. 1, the cutting mechanism 60 is located at a side close to the material outlet of the rotating rod holding clamp 50, the cutting mechanism 60 has a through hole with the telescopic rod 40 as the center, and when the meter counting mechanism 20 feeds back the conveyed material to reach the set length of the single telescopic product, the cutting mechanism 60 cuts the material. The cutting mechanism 60 has 1-2 cutters for cutting the material around the telescoping rod 40.

Specifically, as shown in fig. 1 and 6, moving the clamp 70 will transport the cut casing shrink from the cutting position along the casing shrink rod 40 towards the injection handrail clamp 80. The injection supporting rod clamps are at least two groups. The figure is two groups, and other suitable numbers of groups can be selected, and are not limited herein. The first and second sets of injection rod clamps 802 and 804 are used to clamp and hold the telescopic rod 40 so that the telescopic rod 40 does not move back and forth. When the first set of injection handrail clamps 802 clamp the telescoping pole, the second set of injection 804 handrail clamps are in an open state; the first set of injection centralizer clips 802 are in an open state when the second set of injection centralizer clips 804 clip the telescopic rod 40. The two clamping pieces on each set of injection support rod clamp 80 are respectively provided with an injection nozzle 806 for gas injection and liquid injection in an opposite direction, and the position of the telescoping rod 40 corresponding to the injection support rod clamp is provided with an injection port 406 for gas injection and liquid injection. When the injection rod supporting clamp 80 clamps the telescopic rod 40, the injection nozzle 806 on the injection rod supporting clamp 80 is inserted into the injection port 406 of the telescopic rod 40, the valve inside the telescopic rod 40 is pushed open, two media enter the telescopic rod 40, and are ejected out of the ejection port 408 of the telescopic rod 40 along the cavity of the telescopic rod 40. Because at least one holding rod clamp always conveys media into the rod when the holding rod clamps are switched, uninterrupted air and liquid injection can be ensured at the end of the rod.

Further, the moving clamp 70 is also used to unload the cut telescopic material from the telescopic rod 40. After the sleeve shrinkage material of the cutting segment passes through the last group of rod supporting clamps, the clamp is moved to discharge the sleeve shrinkage material from the sleeve shrinkage rod to be output as a final finished product, or the sleeve shrinkage rod is penetrated into another receiving rod butted with the sleeve shrinkage rod to be used for next procedure treatment.

The sleeving and shrinking machine can realize continuous production and stable operation, and can greatly improve the product quality and the automatic production efficiency.
