Technical Field

[0001] The invention relates to the field of food processing and is particularly applicable to the field of egg roll devices. Background Art

[0002] The finished product form of some foods is a rolled form, such as egg rolls, hawthorn rolls, Swiss rolls and other rolled foods. The existing egg roll processing equipment mainly includes a feeding unit, a baking unit, a winding and forming unit and a power control unit. Egg rolls, in particular, are soft at high temperatures and crispy at room temperature. Sometimes the egg rolls stick to the baking plate after baking. Therefore, whether it is winding or unwinding the multi-layered egg rolls from the winding roller, both the equipment structure and the product processing are challenging processes. The final shape of the egg roll after baking is either winding forming. The existing technology requires winding multiple layers of egg rolls with winding rollers. The other is folding forming. Folding is usually large-scale folding. Folding forming is relatively simpler than winding forming, but the taste and shape of the finished product are less accepted by the public. How to choose different winding rollers, separation components, forming components and other functional components for use alone or in combination is the key to high-quality winding forming and unwinding.

Most of these existing patents suffer from complex structures or numerous defects in their winding performance. Where appropriate, relevant portions of these patents may be cited as prior art in this patent. Reducing the difficulty of unwinding egg rolls and pursuing the highest possible quality for finished egg rolls are constant goals. Summary of the Invention

[0003] A new winding structure is proposed to reduce the pressure of the wound part on the winding roller after winding, reduce the difficulty of unwinding the egg roll, or pursue the highest possible quality of the finished egg roll.

[0004] The forming device includes a winding unit and an unwinding unit. For the winding forming device using a winding roller, whether winding or unwinding, it must be carried out around the winding roller. The new winding roller is connected to the egg roll machine through a dedicated or public frame mounting position, directly integrated or separated from the baking unit. There is at least one winding member that can be wound in multiple layers. The surface of the winding part of the winding member is a trapezoidal structure with at least one linear dimension extending along the axis from the driving end to the outermost end of the free end gradually decreasing. The winding unit has at least one winding member. The winding part has an unequal diameter structure in the axial direction, including a tapered structure with gradually decreasing overall size and a pyramidal structure composed of several inclined planes. The shape of the wound part after winding is roughly cylindrical or approximately cylindrical. Generally, the unequal diameter degree of the outer surface of the egg roll after forming is smaller than the unequal diameter degree of the winding roller; the small end of the winding part is the free end at the outermost end, and the other end is the connection end of the driving mechanism. The large difference in diameter between the large and small ends is conducive to unwinding, but the overall shape of the wound part after winding also has a large and small end and the diameter difference is relatively large. The large V-shape will not make the ends of a multi-layer egg roll neat. Since the wound part is either in a soft state or in a crisp state, the withdrawal of the winding roller after winding is a challenging process. The pressure of the wound part on the winding roller after winding is one of the reasons for the difficulty of the unwinding process. Therefore, various structural forms that can reduce the pressure of the wound part on the winding roller after winding are of great help to the smooth progress of the unwinding process. The preferred small end size is generally not less than 80% of the large end size, or the small end size is not less than 90% of the large end size; the more preferred small end size is not less than 95% of the large end size or less. The unequal diameter winding part in this patent can be at least a truncated cone or a prismatic cone. The conical winding shaft in the prior art is not used for winding multi-layer cylindrical egg rolls. The difference in size between the large and small ends is large, and a conical winding plate is also required. Since the difference in size between the large and small ends of the winding roller in this patent is not large, and the contact surface of the winding roller and the wound part is in parallel contact during winding, the shape of the egg roll wound by the winding roller is roughly the usual multi-layer cylindrical shape.During the winding process, at least one of the winding member's axis or surface is parallel to the contact surface of the wound member. When the winding member surface is parallel to the contact surface of the wound member, the angle between the winding member axis and the contact surface of the wound member is equal to the inclination angle of the truncated cone generatrix. After the winding roller completes multi-layer winding, the wound member exerts pressure and friction on the winding roller. The winding portion of the winding roller is configured as an unequal diameter structure. After winding is completed, the pressure and friction of the wound member on the winding roller are unevenly distributed, with the small end being smaller. After winding is completed, the wound member can continuously decrease as the diameter of the winding roller decreases, which can effectively reduce the pressure and friction between the wound member and the winding roller as the diameter decreases. Since the diameter of the winding roller gradually decreases along the axial direction, the pressure and friction between the wound member and the winding roller can be effectively reduced as the diameter decreases during unwinding. The winding member is connected to a drive mechanism and a controller. The drive mechanism can be electric, mechanical, hydraulic or pneumatic. The controller can be electrically controlled or controlled by an integrated circuit or chip. The existing technology provides a variety of control solutions.

[0005] The new winding roller of the winding unit is connected to the egg roll machine through a dedicated or public frame mounting position. The winding forming device adopts the winding roller for the winding piece. No matter winding or unwinding, it must be carried out around the winding roller. It is directly integrated or separated from the baking unit. The winding and unwinding unit has at least one winding piece, and the surface of the winding part of at least one winding piece is composed of surfaces of different shapes; the pressure of the wound piece on the winding roller after winding is one of the reasons for the difficulty of the unwinding process, so various structural forms that can reduce the pressure of the wound piece on the winding roller after winding are of great help to the smooth progress of the unwinding process. The surface of the winding part of the winding piece is composed of surfaces of different shapes, which can be surfaces with different curvature radii. surface, or it can be a plane at a different position; it can also be a surface with different friction coefficients, different planes, curved surfaces with different curvatures, or a combination of curved surfaces with different friction coefficients; it is divided into several parts along the circumferential direction of the winding roller, and the surfaces of different shapes extend roughly along the axis of the winding roller, and the width along the circumferential arc direction can be equal width, unequal width or dispersed distribution; for example, the surface of an approximately cylindrical or truncated cone has at least several planes arranged along the circumference or a curved surface with a curvature radius greater than the curvature of the cylindrical or truncated cone; the preferred plane or large curvature curved surface has the smaller the width, the better, the more the number, the better, and the more evenly distributed the better. After the winding is completed, since the prototype of the wound piece is mostly circular, The shape or shape is closest to the circumference, so the contact area between the winding roller surface of the circumferential part and the wound workpiece is the largest, and the supporting effect is also the largest. After the winding roller completes multi-layer winding, the pressure and friction of the wound workpiece on the winding roller on the non-circular surface is relatively small, so as the diameter of different parts of the winding roller decreases, the pressure or friction between the winding roller and the wound workpiece is smaller, and the polygonal surface has almost no such effect; at least one winding part of the winding part is composed of planes arranged at intervals along the main line, and the winding part of the winding part has a constant size of at least one line from the driving end to the outermost end; the winding part surface of the winding part can be a circular arc surface and a plane alternately arranged. The larger the number of equal divisions, the better the effect. Since the wound article is either in a soft state or in a crisp state, it is a challenging process for the winding roller to withdraw after winding is completed. The winding part of the winding roller is set to different surface structures, which can effectively reduce the friction between the wound article and the winding roller when the winding roller withdraws the wound article after winding is completed. One end of the winding part of the winding roller is the outermost free end, and the other end is the driving mechanism connection end. The winding article is connected to the driving mechanism and the controller. The driving mechanism can be electric, mechanical, hydraulic or pneumatic. The controller can be electrically controlled or integrated circuit or chip controlled. The existing technology provides a variety of control solutions.

[0006] The new winding roller of the winding unit is connected to the egg roll machine through a dedicated or public frame mounting position. For the winding forming device using the winding roller, whether winding or unwinding, it must be carried out around the winding roller, which is directly integrated or separated from the baking unit. There is at least one winding member, and the winding part of at least one winding member is provided with an airflow structure; the pressure of the wound member on the winding roller after winding is one of the reasons for the difficulty of the unwinding process, so various structural forms that can reduce the pressure of the wound member on the winding roller after winding are conducive to the smooth progress of the unwinding process. The winding part of the winding member has a great help in the operation. The surface shape of the winding part along the axial direction can be cylindrical or truncated cone. One end of the winding part of the winding roller is the free end at the outermost end, and the other end is the driving mechanism connection end. At least the winding part of the winding member can be provided with a hollow air flow passage. The contact surface of the winding surface part of the winding member (the winding contact surface) is provided with a plurality of air flow holes. The air flow holes include those formed by drilling holes on the surface of the winding roller of a common material or formed by a porous material. At least a part of the porous material is a through hole. The air flow holes can be evenly distributed on the contact surface. The more air holes there are in the cloth, the more conducive it is to function, but the processing is complicated. The winding member is also provided with an air flow injection or extraction opening, which can generally be set at the driving connection end of the winding member. The air flow injection or extraction opening can be a single one, shared or separately set. Except for the air flow holes and openings, it can be a closed structure; when winding, the air flow is extracted from the extraction opening of the winding roller and flows out, and the external air enters from the air flow holes. The atmospheric pressure makes the surface of the winding part of the winding member have an adsorption function, and the winding roller can completely solve the problem of the winding roller slipping during winding; when unwinding, the air flow is injected into the winding roller from the air flow injection opening, and the external air flows out from the air flow holes of the winding part of the winding roller through the intermediate air flow path. The outflowing gas has the effect of floating and expanding the wound member, which is beneficial to reducing the friction between the wound member and the winding roller. The winding member is connected to the driving mechanism and the controller. The driving mechanism can be electric, mechanical, hydraulic or pneumatic. The controller can be electrically controlled or integrated circuit or chip controlled. The existing technology provides a variety of control schemes.

[0007] The clamping surface of the unwinding clamping mechanism is adapted to the surface of the wound part after the winding is completed; it is ensured that the contact between the clamping surface and the wound part after winding is full contact. If the outer surface of the wound part after winding is conical, the clamping surface is also adapted to the conical surface. If the surface of the wound part after winding is inclined, the clamping surface is also adapted to the inclined angle. Generally, the unequal diameter degree of the outer surface of the egg roll after formation is smaller than the unequal diameter degree of the winding roller, so the unequal diameter degree of the clamping surface of the unwinding clamping mechanism is smaller than the unequal diameter degree of the winding roller.

[0008] The preferred winding part of the winding member has at least any two of the three structures; the preferred winding part shape structure may include a large and small diameter structure and an airflow structure, a large and small diameter structure and different surface shape structures, an airflow structure and different surface shape structures, a gas storage space and a large and small diameter structure, a gas storage space and different surface shape structures, or a shape structure with all three of airflow structure, large and small diameter structure and different surfaces, or a shape structure with all three of gas storage structure, large and small diameter structure and different surfaces, or other structural combinations.

[0009] The preferred winding member is coordinated with at least one separating member, or forming member, or a combination thereof, at least one of which is matched with the winding member; there is at least one separating member, or forming member, or a combination thereof, at least one of which is coordinated with the winding member; the new winding roller winding member of the winding unit is coordinated with at least one separating member, or forming member, or a combination thereof, at least one of which is matched with the winding member, the combination includes a separating member and a forming member, the separating member is mostly a blade-like shape of a scraper; it can also be a pressurized air flow or fluid that has a separation effect through a nozzle; the forming member is guided by the surface shape to form the wound member; at least one forming member surface is composed of a plane, a curved surface, or a combination thereof, at least one of which is matched with the winding member; the surface shape can be a plane, a curved surface, or a combination thereof, at least one of which is matched with the winding member; usually the planes can have the same or different angles, and the curved surfaces can also be the same or different quadratic curves. In the prior art, the forming component and the separating component are integrated or fixedly connected. In this patent, the forming component and the separating component are separated or movably connected. Separate means that the forming component and the separating component are two separate components in structure, and movably connected means that the forming component and the separating component are two separate components in structure but the two separate components are connected by a movable structure between each other; there is at least one separating component in front of the wound part, and the forming component is coordinated with the separating component, and at least one forming component and the separating component are separated or movably connected; the winding and unwinding unit has at least one separating component or forming component, or a combination thereof, at least one of which can be supported or moved by gravity, elastic force, temperature, or power, or a combination thereof, at least one of which.

[0010] Preferably, the surface of the winding member is parallel to the surface of the wound member, which can ensure that the surface of the winding part of the winding member is in full contact with the contact line where the wound member starts to wind, that is, the main line of the winding member surface is parallel to the surface of the wound member, and the angles between the axis of the wound member and the main line and the angle between the axis of the winding member and the contact surface of the wound member are the same.

[0011] The preferred surface of the winding member is at least one of a truncated cone structure, a circular prism cone structure, or a combination thereof.

[0012] The preferred surface of the winding member is a plane, an inclined surface, a curved surface, a surface with different friction coefficients, or a combination thereof, at least one of which is provided in the winding portion of the winding member with a smooth surface, which is also a non-stick surface, such as a polytetrafluoroethylene coating. The smooth surface has an adverse effect on winding, but is beneficial for unwinding.

[0013] The preferred airflow structure of the winding part of the winding member can realize gas outflow, or inhalation, or a combination thereof, at least one of the functions; since gas outflow or inhalation is in two directions, the gas source supply system should also have the ability to supply gas in two directions. The airflow structure of the winding part of the winding member can realize gas outflow or inhalation independently, and the gas extraction opening and the gas filling opening can be the same or different openings.

[0014] Preferably, the airflow direction of the airflow structure of the winding part of the winding member is non-perpendicular to the surface of the wound member, or perpendicular to the surface of the wound member, or a combination thereof, at least one of them; when the airflow direction is perpendicular to the surface of the wound member, it can play a role of buoyancy and expansion, and when the airflow direction is not perpendicular to the surface of the wound member (the angle between the airflow direction and the axis of the winding member is less than 90 degrees), it can also play a unique unwinding role; when the conditions are right, there is even no need for a clamping unwinding mechanism, such as when the winding member has an unequal diameter structure or a different surface shape structure, or when the surface of the winding part of the winding member has a smooth surface.

[0015] Beneficial effects of the present invention:

[0016] Since the driving connection end of the winding roller has not changed and the shape of the winding part has basically not changed, the control method and other structures can remain unchanged; by reducing the unwinding resistance, the egg roll shape retention rate can be improved; by controlling the gas direction of the winding roller, the success rate of winding and unwinding can be improved.

[0021] In the first embodiment, the most basic winding member can be formed by a winding roller assembly. According to the shape of the wound member, the effective width of the winding part of the winding roller should match the width of the wound member. In order to complete the winding, the driving mechanism can enable the winding roller to have the functions of rotation and positioning movement, including the ability to move linearly and at different angles relative to the wound member; the small end of the winding roller is the outermost free end, and the other end as the large end is the connecting end of the driving mechanism. The diameter difference between the large and small ends is small. The diameters of the winding part of the winding roller at both ends are truncated cones with a difference of 3%. During the winding process, the truncated cone surface of the winding part of the winding roller contacts the wound member as a fully contacted straight line, that is, the main line of the winding roller is parallel to the surface of the wound member, and the winding roller and the winding roller support structure cooperate with each other. The surface of the winding roller is parallel to the surface of the wound object. When the egg roll is baked, the winding roller first moves to the head of the wound object under the action of the driving mechanism to contact the wound object, and then the winding roller starts to rotate and wind under the action of the driving mechanism to separate and wind the object. At the same time, the wound object moves forward driven by the lower baking plate. When the winding is completed, the winding roller driving mechanism drives the winding roller to continue to move to the unwinding position. Since only the shape of the winding part of the winding roller changes slightly, other structures and control methods remain unchanged. The unwinding clamping mechanism can adopt the existing technology. The unwinding clamping mechanism starts to clamp the outer surface of the wound object, and the driving mechanism of the unwinding clamping mechanism drives the clamping mechanism to move relative to the winding roller to start the unwinding process. The existing technology provides enough possible forms.

[0022] In the second embodiment, the winding unit is completed by a winding roller assembly. According to the shape of the wound object, the effective width of the winding part of the winding roller should match the width of the wound object. In order to complete the winding, the driving mechanism can enable the winding roller to have the functions of rotation and positioning movement, including the ability to move linearly and at different angles relative to the wound object; the curved surface of the winding part of the winding roller is cylindrical, and the winding part of the winding roller is axially extended with 6 points that divide the circumference into 6 equal parts as the center line, and 3 air vents are evenly arranged on each center line. There are 6 rows of air vents on the surface of the winding part of the winding roller, and the air flow injection or extraction opening is arranged at the end of the driving end of the winding roller. The winding roller has an air flow path connecting the air vent and the opening. When the egg roll is baked and the wound object is wound, the air source system extracts gas from the air flow extraction opening in the winding roller, and the external gas forms an adsorption effect through the air vent, and the winding roller adsorbs The wound part is wound into shape, and after the final shape is formed, the unwinding action needs to be completed. The winding roller driving mechanism drives the winding roller to continue to move to the unwinding position. During the unwinding process, the air source system delivers gas to the air flow injection opening of the winding roller, and the air vents on the surface of the winding part of the winding roller exhaust outward, which generates buoyancy and shape expansion for the wound part, and reduces the friction between the wound part and the winding roller; for the sake of structural simplicity, the air source system can only deliver gas to or extract gas from the winding part of the winding roller. Since the driving connection end of the winding roller has not changed and the shape of the winding part has basically not changed, the control method and other structures can remain unchanged. The unwinding clamping mechanism adopts the existing technology, and the unwinding clamping mechanism starts to clamp the outer surface of the wound part. The driving mechanism of the unwinding clamping mechanism drives the clamping mechanism to move relative to the winding roller to start the unwinding process. The existing technology provides enough possible forms.

[0023] In the third embodiment, the winding unit can be completed by a winding roller assembly. According to the shape of the wound object, the effective width of the winding part of the winding roller should match the width of the wound object. In order to complete the winding, the driving mechanism can enable the winding roller to have the functions of rotation and positioning movement, including lateral movement and the ability to move at different angles relative to the wound object; the small end of the winding roller is the outermost free end, and the other end is the connection end of the driving mechanism. The winding part of the winding roller is cylindrical, and the 72 points that divide the circumference into 72 equal parts at both ends are numbered in the same order. The lines connecting the points with the same numbers are evenly divided into areas on the axial surface of the winding part of the winding roller. There are 72 areas in total, and the odd-numbered areas are set as arc areas 3 6, the even-numbered areas are set as chordal plane areas, the part between the arc and the chord in the chordal area is removed and set as a plane, the chordal area is 36 plane surfaces, the arc area and the chordal area are adjacently spaced, the arc area fully assumes the contact support role, the chordal area reduces the contact area between the victim part and the winding roller, and effectively reduces the pressure and friction between the wound part and the winding roller. After the winding is completed, the winding roller driving mechanism drives the winding roller to continue to move to the unwinding position, and the unwinding clamping mechanism begins to clamp the outer surface of the wound part. The driving mechanism of the unwinding clamping mechanism drives the clamping mechanism to move relative to the winding roller to start the unwinding process. The existing technology provides enough possible forms.

[0024] In the fourth embodiment, the winding unit can be completed by a winding roller assembly. According to the shape of the wound object, the effective width of the winding part of the winding roller should match the width of the wound object. In order to complete the winding, the driving mechanism can enable the winding roller to have the functions of rotation and positioning movement, including lateral movement and the ability to move at different angles relative to the wound object; the small end of the winding roller is the outermost free end, and the other end is the connection end of the driving mechanism. The large difference in diameter between the large and small ends is conducive to unwinding. The winding part of the winding roller is a truncated cone with a diameter difference of 2% between the large and small ends. The winding roller has two diameters, large and small. The line connecting the six points in the same direction that divide the circumference into six equal parts is the center line. On each center line, four air vents are evenly arranged axially on the winding part of the winding roller. There are a total of six rows of air vents on the winding part of the winding roller. The air flow injection or extraction opening is arranged at the end of the driving end of the winding roller. The winding roller and the winding roller support structure cooperate with each other to make the surface of the winding roller parallel to the surface of the wound part. The axial surface of the winding part of the winding roller is a strip or an overall smooth surface. When the egg roll is baked and the wound part is wound, the winding roller first moves to the head of the wound part under the action of the driving mechanism to contact the wound part. The winding part, the truncated cone-shaped surface of the winding part of the winding roller contacts the wound part in a straight line with full contact, that is, the generatrix of the winding roller is parallel to the surface of the wound part. The wound part moves forward driven by the lower baking plate, and the air source system extracts gas from the air flow extraction opening in the winding roller, and the vent forms an adsorption effect. The winding roller adsorbs the wound part and winds it into shape; after the final formation, the unwinding action needs to be completed. During the unwinding process, the winding roller drive mechanism drives the winding roller to continue to move to the unwinding position, and the air source system delivers gas to the air flow injection opening of the winding roller. The winding roller The vent holes exhaust air outward, generating buoyancy and shape expansion on the wound article, reducing the friction between the wound article and the winding roller. For the sake of structural simplicity, the air source system can only deliver or extract gas to the winding part of the winding roller, and the unwinding clamping mechanism begins to clamp the outer surface of the wound article. The driving mechanism of the unwinding clamping mechanism drives the clamping mechanism to move relative to the winding roller to start the unwinding process. Since the driving connection end of the winding roller has not changed and the shape of the winding part has basically not changed, the control method and other structures can remain unchanged. The existing technology provides enough possible forms.
