As shown in fig. 1 to 6, a double-dial shrink structure for shrinking a cylindrical casing 5, which is fitted over and fed along a filling tube 1 of a filling apparatus, into a casing tube having tight wrinkles;

the double-shifting-wheel shrinkage structure comprises a first shifting wheel 2 and a second shifting wheel 3 which are oppositely arranged on two sides of the filling pipe 1, and the circumferential rotating directions of the shifting wheels of the first shifting wheel 2 and the second shifting wheel 3 are respectively suitable for pushing the casing 5 to the casing feeding direction;

the first shifting wheel 2 and the second shifting wheel 3 are respectively provided with a plurality of shifting wheel teeth or shifting pieces 4 which are uniformly distributed on the circumferential surface of the shifting wheel, and each shifting wheel tooth or shifting piece 4 is provided with a tooth top surface 42 positioned on the radial periphery and two tooth side surfaces 43 positioned on two sides of the shifting wheel tooth or shifting piece 4;

with the rotation of the first shifting wheel 2 and the second shifting wheel 3, the tooth top surface 42 of the shifting gear tooth or the shifting piece 4 of each first shifting wheel 1 and the tooth top surface 42 of one shifting gear tooth or the shifting piece 4 of the second shifting wheel 3 can be respectively squeezed into the space of the casing 5 on two sides of the radial circumference of the casing 5 in an opposite manner, and the casing 5 is pushed to form a tight fold towards the feeding direction of the casing 5 by the tooth side surface 43 facing the feeding direction of the casing 5.

Although it is conventional to arrange a thumb wheel structure on a sausage casing shrinking device to shrink sausage casings, the sausage casings produced by sausage casing manufacturers need to be shrunk into sausage casing rods with the same length when being transported and sold, and in order to prevent the sausage casings from being scattered in the transportation process and the sausage casings from being scattered and not being smoothly inserted into filling tubes when being filled by customers, the wrinkles of the sausage casings are required to form the same circle of thread lines, and the sausage casings shrunk into the sausage casing tubes as compact as possible are not easy to loosen. In order to improve the aesthetic property of the casing shrink and increase the sales volume, the appearance of the wrinkles on the casing shrink is required to be uniform and smooth, and in order to achieve the requirement, the thumb wheel structure on the casing shrink equipment is required to be arranged in a complicated way to achieve the shape of the continuous thread generated on the casing, which increases the manufacturing cost of the thumb wheel structure. In filling enterprises, the sausage casing can be directly used for filling only by shrinking the sausage casing in a filling tube, so that the sausage casing can be folded and compressed only by the on-site shrinking structure, the requirements on the uniformity of appearance and the folding shape are not required, the shrunk sausage casing does not need to be transported and sold, and the cost of filling equipment is reduced as much as possible, so that the existing shifting wheel structure on the sausage casing shrinking equipment is not suitable for being directly used on the filling equipment.

In the technical scheme, the first shifting wheel 2 and the second shifting wheel 3 with the linear tooth profiles 41 are arranged, and the casing is pushed to form tight wrinkles by the linear shifting wheel teeth or the shifting sheet 4 through the rotation of the first shifting wheel 2 and the second shifting wheel 3, so that manual shrinkage is replaced, the time and labor are saved, the efficiency is high, the shrinkage effect is good, the requirements of casing shrinkage and filling are met on filling equipment, and the filling production cost is reduced; and the whole double-shifting-wheel shrinkage structure is simple in structure, the processing technology of the linear shifting wheel teeth or the shifting sheet 4 is simple, the equipment cost of the whole double-shifting-wheel shrinkage structure can be effectively reduced, and the requirement of the filling industry is met.

In practical applications, the top surface 42 may be formed in various shapes (e.g., a straight plane, a V-shaped plane) as long as the casing is pushed in the feeding direction of the casing to form a tight fold. The tooth top surface 42 of the poking wheel teeth or the poking sheets 4 is an inwards concave curved surface, can be an arc surface matched with the radial circumference of the filling pipe, and can also be an approximate V-shaped surface tangent with the radial circumference of the filling pipe.

Preferably, the top surfaces 42 of the first thumb wheel 2 and the second thumb wheel 3 are arranged in a V-shaped surface. Because if the top surface 42 of the top gear is a straight plane, the top surface 42 of the first driving wheel 2 and the top surface 42 of the second driving wheel 3 have only 2 contact points with the casing 5, which results in that the casing fold is not tight enough and loose. In the embodiment, the V-shaped top surface 42 of the first thumb wheel 2 and the V-shaped top surface 42 of the second thumb wheel 3 form more than 2 contact points with the casing, so that the contact area with the casing 5 can be increased, the driving force for forming wrinkles on the casing is improved, and the casing is enabled to form tighter wrinkles. Further, the V-shaped top surface 42 also makes the first thumb wheel 2 and the second thumb wheel 3 suitable for use with casings and filling tubes of different diameter sizes.

Specifically, the heights of the paddle teeth or the paddles 4 of the first paddle wheel 2 and the second paddle wheel 3 are designed to increase the friction force pushing the casing 5. Preferably, as shown in fig. 7, the height H of the paddle teeth or paddles 4 of the first paddle wheel 2 and the second paddle wheel 3 is larger than the diameter D of the casing 5 to be processed in an inflated state.

Because the first thumb wheel 2 and the second thumb wheel 3 must be driven to rotate to push the casing 5 to form the tight wrinkles in the casing feeding direction when the casing 5 is shrunk, in order to solve the problem, the double-thumb wheel shrinking structure comprises a thumb wheel driving device which can drive the first thumb wheel 2 and the second thumb wheel 3 to rotate to push the casing 5 to form the tight wrinkles in the casing feeding direction.

Preferably, the thumb wheel driving device comprises a first thumb wheel rotating shaft penetrating through the first thumb wheel 2 and a second thumb wheel rotating shaft penetrating through the second thumb wheel 3, and the first thumb wheel rotating shaft and the second thumb wheel rotating shaft are designed such that only rotating the first thumb wheel rotating shaft realizes reverse rotation of the first thumb wheel 2 and the second thumb wheel 3 to push the casing 5 to the feeding direction of the casing to form tight wrinkles, or only rotating the second thumb wheel rotating shaft realizes reverse rotation of the first thumb wheel 2 and the second thumb wheel 3 to push the casing 5 to the feeding direction of the casing to form tight wrinkles, or simultaneously rotating the first thumb wheel rotating shaft and the second thumb wheel rotating shaft realizes reverse rotation of the first thumb wheel 2 and the second thumb wheel 3 to push the casing 5 to the feeding direction of the casing to form tight wrinkles.

Because the casing 5 needs to be filled after the casing is completely shrunk on the filling tube 1, if the first dial wheel 2 and the second dial wheel 3 are still continuously positioned on two sides of the filling tube 1, the filling of the casing 5 is obstructed, and at this time, the first dial wheel 2 and the second dial wheel 3 need to be temporarily moved away, in order to solve the problem, the double-dial-wheel shrinking structure further comprises a dial wheel moving device, wherein the dial wheel moving device is designed to drive the first dial wheel 2 and the second dial wheel 3 to move away from two sides of the filling tube 1 so as to avoid obstructing the casing shrinking filling, or drive the first dial wheel 2 and the second dial wheel 3 to move and reset to two sides of the filling tube 1 so as to shrink the casing.

As a preferable scheme, the dial wheel moving device comprises a dial wheel swinging mechanism and a dial wheel overturning mechanism, and the dial wheel swinging mechanism is designed to drive the first dial wheel 2 and the second dial wheel 3 to swing away from two sides of the filling tube 1, or drive the first dial wheel 2 and the second dial wheel 3 to swing and reset to two sides of the filling tube 1, as shown in fig. 8; the poking wheel turnover mechanism drives the first poking wheel 2 and the second poking wheel 3 which are swung away from two sides of the filling pipe 1 to turn over for a certain angle so as to avoid hindering the filling of the casing shrink by sleeving, or drives the first poking wheel 2 and the second poking wheel 3 to turn over and reset, as shown in fig. 9 and 10.

As a preferable scheme, the shifting wheel swinging mechanism and the shifting wheel turnover mechanism can axially slide on a rotating shaft parallel to the filling tube 1, when the casing is shrunk, the first shifting wheel 2 and the second shifting wheel 3 simultaneously slide outwards from one side, close to the filling machine body, of the filling tube 1 along with the shifting wheel swinging mechanism and the shifting wheel turnover mechanism on the rotating shaft parallel to the filling tube 1, namely the first shifting wheel 2 and the second shifting wheel 3 continuously push the casing 5 to shrink in the sleeving manner, and slide outwards from one side, close to the filling machine body, of the filling tube 1 along with the shifting wheel swinging mechanism and the shifting wheel turnover mechanism on the rotating shaft parallel to the filling tube 1, so that the shrinking length of the casing 5 on the filling tube 1 can be increased, the casing 5 can be folded more compactly from the root of the filling tube 1 to the outlet end in sequence, and longer meters can be filled at one time.
