The invention relates to a lever labor-saving wrapper rolling device, which comprises a panel 1, a sliding plate 3, a handle 7, a clamping seat 8, a fixing frame 11, a dough rolling device, a fixing device and a guiding device, as shown in figures 1, 2 and 3, wherein the panel 1 is a rectangular wood board, the guiding device is arranged on one side of the panel through the fixing device, corresponding components of the guiding device are connected with the sliding plate 3, the position of a connecting point is fixed in the height direction, the sliding plate 3 is clamped on the corresponding components of the dough rolling device through the clamping seat 8, the handle 7 is arranged at the front end of the sliding plate 3, the front and back positions of the sliding plate 3 on the clamping seat 8 are properly adjusted to change the distance of the sliding plate 3 extending forwards out of the dough rolling device, so as to change the size of a lever power arm taking the dough rolling device as a fulcrum, small dough prefabricated in advance is placed on the panel 1, the handle 7 is pushed by hand to move forwards and backwards and downwards to apply small pressure according to the lever principle, can make and roll the device and produce great pressure downwards, slide 3 drives the back-and-forth movement of cassette 8, and the cassette 8 drives and rolls the device around on panel 1 and roll extrusion, rolls the little dough and presses into the face skin finished product.

The guide device comprises a cylindrical pin 6, a guide pipe 10, a positioning sleeve 15, a linear bearing 16, a stop nail 17 and a shaft 18; the guide device is made of light metal, the guide tube 10 is cylindrical, a pair of linear bearings 16 are arranged in the guide tube through two positioning sleeves 15, the shafts 18 are arranged in inner holes of the linear bearings 16, the shafts 18 and the linear bearings 16 are in clearance fit, the shafts 18 can slide along the axis direction, the rear ends of the shafts 18 are provided with stop nails 17, so that the shafts 18 cannot be separated, the front ends of the shafts 18 are connected with the sliding plate 3 through cylindrical pins 6, the sliding plate 3 can rotate around the cylindrical pins 6, but the cylindrical pins 6 cannot move up and down due to the constraint effect of the two linear bearings 16.

Preferably, the linear bearing 16 is a self-lubricating LIN series plastic linear bearing, the nominal inner diameter of the linear bearing is 10mm, the maximum bearing capacity is 870N, the sliding friction material is CSB-EPB13, the linear bearing is free of maintenance, long-term dry running and noiseless, is suitable for textile machinery and food packaging machinery, can run in dust for a long time, is corrosion-resistant, and is suitable for disinfection and cleaning and light-weight design.

The rolling device is shown in figure 2 and comprises a balance shaft 2, a rolling shaft 9, a circular plate 12, a needle bearing 13 and a connecting shaft 14; the connecting shaft 14 is in a metal cylindrical shape, a pair of needle roller bearings 13 are arranged on the connecting shaft 14 side by side, circular plates 12 are arranged at two ends of the connecting shaft, the left end of each circular plate 12 is fixedly connected with a rolling shaft 9, the right end of each circular plate 12 is fixedly connected with a balance shaft 2, the rolling shaft 9 and the balance shaft 2 are hollow cylinders made of light metal and can be connected with the circular plates 12 in a welding mode and the like. The rolling shaft 9 can also be made into a waist drum shape with a slightly thicker middle part, the diameter of the balance shaft 2 is the same as that of the rolling shaft 9, so that the force of the handle 7 acting on the rolling shaft 9 is balanced, and the rolling shaft 9 can apply pressure to the dough cover in a balanced manner.

Preferably, the needle bearing 13 adopts an HK1014-2 double-sided sealing type needle bearing, the shaft diameter of an inner hole of the needle bearing is 10mm, and the outer diameter of the inner hole of the needle bearing is 14 mm; the width is 12mm, the limit rotating speed is 17000rpm, and the inner hole journal is in contact with the roller pin, so the hardness of the connecting shaft 14 is required to be slightly higher. A gap of 0.2-0.4mm is reserved between the outer end face of the bearing and the circular plate 12 to reduce mutual friction, and the needle bearing 13 is extremely small in radial force and used under the condition of extremely low rotating speed, so that the bearing can be kept dry without lubrication.

The handle 7 is a cylinder made of food-grade rubber material.

As shown in fig. 4, the clamping seat 8 has a square groove at the upper end, screw holes 19 are respectively arranged at the front side and the rear side of the bottom of the square groove, an arc groove is arranged at the lower end, elastic edges are formed at the two sides of the lower end of the arc groove, and the needle roller bearing 13 is clamped in the arc groove by the clamping seat 8 through the elastic edges during operation, so as to drive the rolling device to operate.

The slide plate 3 is a cuboid light metal plate and is embedded into a groove in the upper portion of the clamping seat 8, a handle 7 at the front end of the slide plate 3 is slightly higher than the upper surface of the slide plate 3, the rear end of the slide plate is hinged with a shaft 18 through a cylindrical pin 6, a long hole 5 is formed in the middle of the slide plate 3, a fastening screw 4 penetrates through the long hole 5 and is screwed into a screw hole 19 in the upper portion of the clamping seat 8, and the screw head fixes the slide plate 3 after the fastening screw 4 is screwed tightly. When the handle 7 is pressed downwards, the rolling shaft 9 is pressed through the clamping seat 8, the longer the distance that the sliding plate 3 extends forwards out of the front end of the rolling shaft 9 is, the more labor is saved when the handle 7 is pressed downwards. At the moment, the cylindrical pin 6 is a fixed point in the height direction, the sliding plate 3 is transversely pressed on the rolling device, when the handle 7 is pressed downwards, the rolling device is a supporting point to form a lever mechanism, the distance that the sliding plate 3 extends forwards out of the front end of the rolling shaft 9 is the length of the lever power arm, and the lever principle shows that the longer the power arm is, the more labor is saved. For example, when the runner 3 extends forward from the rolling pin 9 by a distance equal to the rolling pin to pin 6, half the force is saved.

The fixing frame 11 is a metal frame with an opening at one end, as shown in fig. 5, the upper end is made into a cutting plane, the guide tube 10 can be welded on the cutting plane, the lower end is provided with a pair of fixing screws 20, and the upper ends of the screws are provided with rotatable pressing sheets 21, so that the fixing frame 11 and the guide device are more firmly installed.

When the rolling device is used, all the components are connected according to the figure 1, the height of the guide device is adjusted, and the shaft 18 and the sliding plate 3 are approximately at the same height by adding or subtracting a wooden gasket between the upper surface of the panel 1 and the fixed frame 11.

The using method is the same as that of the traditional rolling pin, the handle 7 is pushed forwards and backwards, so that the sliding plate 3 drives the clamping seat 8 and the rolling device to roll on the panel 1 forwards and backwards, the rolling shaft 9 can roll small dough into a finished product of dough sheets, the processed dumpling sheets are completely the same as those of the traditional hand-rolled dough sheets, and after an operator is slightly skilled, the dumpling sheets can be rolled for a long time quickly and easily, so that the labor intensity is reduced, and the efficiency is improved.

After the detachable cylindrical pin 6 is pulled out, the fixing frame 11 and the guiding device are detached, the fastening screw 4 can be screwed off to detach the handle 7 and the sliding plate 3, and finally the clamping seat 8 is pulled out from the needle bearing 13 with slight force, so that the corresponding components can be cleaned and stored.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
