Description

Technical Field

[0001] The present invention relates to the field of food processing, and specifically to a finished bread cooling and transportation production line. Background Art

[0002] Bread is a widely consumed food, usually made by mixing flour, water, yeast and other ingredients, and then processed through processes such as fermentation and baking. With the development of the modern food industry, the mass production of bread has changed from relying on a large number of workers to mechanized production.

[0003] In the later stage of bread production, after the baked bread products are completed and before being packed, it is necessary to cool them down. The commonly used cooling methods at present include natural cooling and air-cooling. Among them, natural cooling is a method of automatically cooling the bread on the transportation production line, which is selected when the length of the production line for baking and packing in the factory is long enough to leave sufficient cooling time. Compared with natural cooling, air-cooling blows air on the bread products quickly through the set fan assembly, greatly improving the heat dissipation efficiency of the bread products.

[0004] However, when the above-mentioned bread production factory uses the air-cooling method to cool the bread products on the transportation production line, due to the reduced quality of the bread, in order to avoid situations such as the bread rolling during the blowing process, the size of the blowing air volume cannot be set too large, and at the same time, the blowing can often only cool one side of the bread continuously, thus weakening the effect of air-cooling. Summary of the Invention

[0007] As a further solution of the present invention, the two sets of auxiliary belts are driven to rotate by corresponding conveying power motors.

[0008] As a further solution of the present invention, two groups of guide columns are horizontally fixedly installed on the storage plate, and the bottoms of the two groups of clamping frames are correspondingly provided with guide holes for slidingly connecting the two groups of guide columns.

[0009] As a further solution of the present invention, the downward pressure net is installed on the upper part of the storage plate by means of a telescopic connecting rod so as to be lifted and slidably mounted thereon.

[0010] As a further solution of the present invention, the driving assembly includes two sets of driving screw rods and a double-headed driving motor;

[0011] The double-headed driving motor is fixedly installed in the middle of the storage plate, and the close ends of the two sets of driving screws are coaxially installed on the output shafts at both ends of the double-headed driving motor, and are installed on fixed inner nuts at the connecting holes at the bottom of the two sets of clamping frames to form a spiral pair transmission.

[0020] Compared with the prior art, the present invention provides a cooling structure in the existing device for cooling and transporting bread products on an air-cooled production line. Multiple horizontally arranged placing plates in the cooling structure can connect two conveying belts to form a passage for the linear passage of baking trays;

[0021] 1.

The rotating assembly drives the rotating column to rotate at a constant speed, driving the swinging rotation of the storage plate to continuously adjust the windward angle of the baked bread products on the baking tray. Since the circumferences of the baked bread products can all face the air supply direction, it avoids the problem that in the existing air-cooling blowing, it can often only continuously cool one side of the bread, thus weakening the air-cooling effect.

[0035] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0036] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 And Figure 8As shown, in an embodiment of the present invention, a cooling and transporting production line for finished bread 6 is provided, which is used to cool the finished bread 6 placed on a baking tray 5, and includes a conveyor belt 200, a fan assembly 100 and a cooling structure 300, wherein two groups of conveyor belts 200 are respectively arranged on both sides of the cooling structure 300, the fan assembly 100 is installed on the upper side of the cooling structure 300, and the cooling structure 300 is installed on the bottom plate 400, which includes multiple groups of placement plates 7 and a swing structure, wherein the multiple groups of placement plates 7 are sequentially arranged along a linear line and are connected to the conveyor belts 200 at both ends. The conveying belt 200 is connected to form a linear passage for the baking tray 5 to pass through. A group of clamping frames 10 for clamping on both sides of the baking tray 5 are slidably installed at both ends of the storage plate 7. A group of auxiliary belts 16 are installed on each group of clamping frames 10. The two groups of clamping frames 10 are driven to move in a mirror image by a driving assembly 12 installed on the storage plate 7. A group of pressing nets 8 are installed on the upper end of the storage plate 7 for lifting. The pressing nets 8 are driven to lift by the lifting assembly 14 on the storage plate 7. The lifting assembly 14 is driven to lift and lower through the first transmission assembly 15 and the driving assembly 12. The end of the storage plate 7 away from the feeding of the finished bread product 6 is vertically slidably installed with a baffle 9, the baffle 9 is elastically connected to the storage plate 7 through multiple sets of elastic members, the baffle 9 is transmission-connected to the lower pressure net 8 through a second transmission assembly 13, the swing structure is installed at the bottom of the corresponding storage plate 7, and includes a rotating column 1801, a driving block 1807, a fixed column 1802 and a rotating ring 1803, the rotating column 1801 is correspondingly rotatably installed on the support frame 17 on the bottom plate 400, and is driven to rotate by the rotating assembly 19, The driving block 1807 is slidably mounted on the guide rail 1808 provided on the upper end surface of the rotating column 1801, the fixed column 1802 is fixedly mounted on the bottom of the storage plate 7, two groups of limit columns 1806 are symmetrically mounted on both sides thereof, and a transmission column 1804 is slidably mounted on the bottom thereof along its axial direction, the transmission column 1804 is rotatably connected to the driving block 1807 through a universal joint 1809, the slewing ring 1803 is rotatably mounted on the upper end of the support frame 17, and is rotatably connected to the limit columns 1806 provided on both sides of the fixed column 1802;

[0037] Specifically, when the present invention realizes the cooling of the finished bread 6, multiple groups of baking trays 5 with the finished bread 6 are transported to the cooling structure 300 by the conveyor belt 200 on one side for continued support. Multiple groups of storage plates 7 in the cooling structure 300 can correspond to the placement of one group of baking trays 5. When the multiple groups of baking trays 5 move to the upper part of the corresponding storage plate 7, the conveyor belt 200 stops conveying, and the two groups of auxiliary belts 16 on the storage plate 7 rotate and convey accordingly to adjust the position of the baking tray 5 supported thereon. At the same time, the driving component 12 and the lifting component 14 correspondingly connected by the first transmission component 15 drive the two groups of clamping frames 10 to clamp on both sides of the baking tray 5, and the pressing net 8 on the upper side of the storage plate 7 descends to press down and fix the finished bread 6 on the baking tray 5.

[0038] After the clamping and positioning of the baking tray 5 and the fixing of the finished bread 6 are completed, the blower assembly 100 can be turned on at this time to perform air cooling on the finished bread 6. When the blower assembly 100 is turned on, the swinging assembly 18 is started at the same time. The blowing of the blower assembly 100 cools the finished bread 6. At the same time, the swinging assembly 18 drives the placing plate 7 and the baking tray 5 thereon to swing, continuously adjusting the windward angle of the finished bread 6 on the baking tray 5 to improve the cooling efficiency of the finished bread 6. Specifically, when the swinging assembly 18 performs swinging drive, when the driving block 1807 slides from the center of the rotating column 1801 to the eccentric position, at this time, the transmission column 1804 extends out of the sliding cavity axially opened by the fixed column 1802, and synchronously drives the transmission column 1804 and the fixed column 1802 to be inclined, driving the placing plate 7 to move from the horizontal state to the inclined state. At this time, the rotating column 1801 can be driven to rotate at a constant speed by the rotating assembly 19. While driving the driving block 1807 to perform circular motion, it drives the transmission column 1804 rotatably connected through the universal joint 1809 to rotate, and drives the fixed column 1802 limited by the rotating ring 1803 to swing and rotate, so as to realize the swinging rotation of the placing plate 7. The two ends of the rotating ring 1803 are respectively rotatably connected to the two side support plates 1701 at the upper end of the support frame 17 through the connecting columns 1805. At the same time, the axis connection of the limiting columns 1806 at both ends of the fixed column 1802 and the axis connection of the two connecting columns 1805 are designed to be perpendicular. In the present invention, by designing the slidable driving block 1807, when the driving block 1807 slides to the center of the rotating column 1801, at this time, both the transmission column 1804 and the fixed column 1802 are in the vertical state, and at this time, the placing plate 7 is in the horizontal state, and the baking tray 5 can be received. When the driving block 1807 slides to the other end of the guiding slide rail 1808 and is in the eccentric position of the rotating column 1801, at this time, the placing plate 7 can be driven to be inclined synchronously by the inclined transmission of the transmission column 1804.

[0039] As Figure 3 and Figure 4 shown, in the embodiment of the present invention, the two groups of auxiliary belts 16 are driven to rotate by the corresponding conveying power motors. In the present invention, the two groups of auxiliary belts 16 are turned on when the placing plate 7 is conveyed, and are turned off after the two clamping frames 10 in the cooling structure 300 complete the clamping of the baking tray 5. After the baking tray 5 is conveyed to the clamping position by the two groups of auxiliary belts 16, one end of it is blocked by the baffle 9 installed on the discharging side of the placing plate 7, so as to prevent the baking tray 5 from moving and separating a part of its body from the baking tray 5 during the clamping process of the two clamping frames 10 due to the corresponding conveying of the two groups of auxiliary belts 16. The two groups of auxiliary belts 16 are controlled and driven by the corresponding conveying power motors during conveying to maintain the same conveying speed.

[0040] As Figure 4As shown, in the embodiment of the present invention, two groups of guide columns 11 are horizontally and fixedly installed on the placement plate 7. Corresponding guide holes for slidably connecting the two groups of guide columns 11 are provided at the bottoms of the two groups of clamping frames 10. When the driving assembly 12 drives the two groups of clamping frames 10 to move mirror-symmetrically towards the middle, the movement of the two groups of clamping frames 10 is guided and limited by the two groups of guide columns 11. Of course, in actual design, the two groups of guide columns 11 can also be replaced with other components with limiting and guiding capabilities, such as limiting tracks.

[0041] Further, the pressing net 8 is installed on the upper part of the placement plate 7 through the telescopic connecting rods 20 in a lifting and sliding manner. In the present invention, a group of telescopic connecting rods 20 are correspondingly installed at the four corners of the pressing net 8. When the pressing net 8 moves up and down, the four groups of telescopic connecting rods 20 contract correspondingly to ensure the stability of the movement of the pressing net 8.

[0042] As Figure 4 and Figure 5 As shown, in the embodiment of the present invention, the driving assembly 12 includes two groups of driving lead screws 1202 and a double-headed driving motor 1201. The double-headed driving motor 1201 is fixedly installed in the middle of the placement plate 7. The proximal ends of the two groups of driving lead screws 1202 are coaxially installed on the output shafts at both ends of the double-headed driving motor 1201, and are in a screw pair transmission with the fixed internal nuts installed at the communication holes at the bottoms of the two groups of clamping frames 10. When the baking tray 5 moves to the upper part of the placement plate 7 and the two groups of clamping frames 10 fix and clamp both ends of the baking tray 5, the double-headed driving motor 1201 is started to drive the output shafts at both ends to rotate synchronously, and drive the two groups of driving lead screws 1202 to rotate synchronously. Through the transmission connection between the driving lead screws 1202 and the fixed internal nuts, the two groups of clamping frames 10 are driven to move mirror-symmetrically towards the middle and are respectively clamped on both sides of the placement plate 7. Of course, in actual design, other components with mirror driving capabilities can also be selected to replace the driving assembly 12 of the present invention. For example, the driving lead screws 1202 threadedly connected to the bottoms of the two groups of clamping frames 10 can also be replaced with a double-threaded rod. At this time, the two groups of corresponding clamping frames 10 are mirror-threadedly engaged at both ends of the double-threaded rod, and a driving motor drives the double-threaded rod to rotate to realize the driving operation of the two groups of clamping frames 10. The present invention does not have strict requirements for the driving assembly 12.

[0043] Further, the lifting assembly 14 includes a rotary stud 1401 and a fixed screw tube 1402. The rotary stud 1401 is rotatably installed on the storage plate 7 and is drivingly connected to the end of the corresponding side driving lead screw 1202 through a first transmission assembly 15. The fixed screw tube 1402 is fixedly installed on the side of the lower pressing net 8, and an internal screw hole for helically connecting the end of the rotary stud 1401 is provided at the bottom thereof. When the lifting assembly 14 realizes the lifting drive of the lower pressing net 8, the rotary stud 1401 is driven to rotate by driving the driving lead screw 1202 to rotate. The rotary stud 1401 is threadedly connected to the fixed screw tube 1402 to drive the fixed screw tube 1402 and the lower pressing net 8 to move up and down correspondingly. By adjusting the rotation direction of the rotary stud 1401, the lifting and moving direction of the lower pressing net 8 is correspondingly adjusted;

[0044] Still further, the first transmission assembly 15 for drivingly connecting the driving lead screw 1202 and the rotary stud 1401 in the present invention includes a rotary worm gear 1501 and a transmission worm 1502. The rotary worm gear 1501 is coaxially installed at the bottom of the rotary stud 1401. The transmission worm 1502 is coaxially installed at the end of the corresponding driving lead screw 1202 and meshes with the rotary worm gear 1501 for driving. When the driving lead screw 1202 rotates, it drives the transmission worm 1502 at its end to rotate, and drives the rotary worm gear 1501 meshingly connected thereto and the rotary stud 1401 coaxially connected thereto to rotate, thereby realizing the driving connection. When the two clamping frames 10 are driven by the driving assembly 12 to move mirror-symmetrically to clamp or release the baking tray 5, the lower pressing net 8 is correspondingly driven to descend or ascend, and cooperates to realize the pressing and fixing or releasing and detaching operation of the bread product 6;

[0045] Such as Figure 4 And Figure 5As shown, in the embodiment of the present invention, the second transmission assembly 13 includes a guide wheel 1302 and a transmission rope 1301, the guide wheel 1302 is rotatably installed on the storage plate 7 through a mounting column, one end of the transmission rope 1301 is fixedly connected to the lower pressure net 8, and the other end is fixedly connected to the baffle 9, the middle part of the transmission rope 1301 is arranged on the guide wheel 1302 to form a V-shaped transmission structure, the baffle 9 in this embodiment is an L-shaped structure, and a plurality of limiting holes are provided on the horizontal plate at the bottom of the baffle 9, each limiting hole is correspondingly slidably connected to a plurality of groups of positioning columns 21 at the bottom of the storage plate 7, and the bottom of the horizontal plate is elastically connected to the bottom of the positioning column 21 through a connecting spring 22. Next, when the baffle 9 has not moved upward to the blocking position, the multiple sets of connecting springs 22 are in a compressed state, providing an elastic supporting force for the baffle 9 to slide upward. When the lower pressure plate is driven downward by force, one end of the transmission rope 1301 connected to the lower pressure net 8 descends, and supported by the elastic force of the multiple connecting springs 22, the baffle 9 moves upward, and one end of the transmission rope 1301 connected to the baffle 9 moves upward, so that the clamping frame 10 drives the mirror clamping to drive the lower pressure net 8 to descend to achieve the downward pressure and fixation of the finished bread product 6, while driving the baffle 9 to move upward to the blocking position and contact with one end of the baking tray 5, so as to prevent the baking tray 5 from leaving the supporting range of the storage plate 7 during the driving process of the auxiliary belt 16.

[0046] like Figure 6 As shown, in the embodiment of the present invention, the rotary assembly 19 includes a rotary drive motor 1901, a drive gear 1902 and a transmission gear ring 1903. The rotary drive motor 1901 is fixedly mounted on the support frame 17, and the drive gear 1902 is fixedly mounted on the end of the rotary drive motor 1901. The transmission gear ring 1903 is coaxially mounted on the outside of the rotary column 1801 and meshes with the drive gear 1902 for transmission. In the present invention, when the drive block 1807 slides to the other end of the guide rail 1808 and is in the eccentric position of the rotary column 1801, the rotary drive motor 1901 can be turned on at this time to drive the drive gear 1902 to rotate, and the transmission drives the transmission gear ring 1903 and the rotary column 1801 to rotate at a uniform speed, driving the tilted storage plate 7 to reciprocate and swing;

[0047] Furthermore, the driving block 1807 is slidably installed on the guide rail 1808 by electromagnetic drive, one end of the guide rail 1808 is fixed at the center of the upper end surface of the rotating column 1801, and is linearly arranged along the radial direction of the rotating column 1801. When the storage plate 7 switches between the horizontal and inclined states, the driving block 1807 can be electromagnetically driven to slide along the guide rail 1808 and make corresponding adjustments.

[0048] In summary, the present invention provides a cooling structure 300 within the device for the finished bread products 6 on the existing air-cooled cooling and transportation production line. Multiple horizontally arranged placement plates 7 within the cooling structure 300 can connect two conveyor belts 200 to form a channel for the linear passage of baking trays 5. When multiple baking trays 5 are driven by the cooperation of the conveyor belt 200 and the auxiliary belt 16 to move onto the corresponding placement plates 7, at this time, while the conveyor belt 200 is stopped, the two auxiliary belts 16 continue to rotate and convey. At the same time, the driving assembly 12 drives the two clamping frames 10 to move mirror-symmetrically to clamp and fix the baking trays 5 supported thereon. Meanwhile, the pressing net 8 above the placement plate 7 is driven to descend and the baffle 9 on the discharge side of the placement plate 7 is lifted to fix the baking trays 5 and press down and fix the bread products 6 thereon. At this time, the blower assembly 100 is turned on for air-cooling the bread products 6. At the same time, the driving block 1807 within the swinging assembly 18 slides from the center of the rotating column 1801 to an eccentric position, driving the transmission column 1804, the fixed column 1802, and the placement plate 7 to tilt. By driving the rotating column 1801 to rotate uniformly through the rotating assembly 19, the swinging rotation of the placement plate 7 is driven, continuously adjusting the windward angle of the bread products 6 on the baking trays 5, improving the cooling efficiency of the bread products 6. Thus, not only is the problem of reducing the air volume size due to avoiding bread rolling and other situations during the existing air-cooling process avoided, but also since the peripheral sides of the bread products 6 can all face the air supply direction, the problem that the existing air-cooling blowing can often only continuously cool one side of the bread, thereby weakening the air-cooling effect, is avoided.

[0049] In this solution, a controller is also provided. The controller is arranged on the device. During use, each electrical device can be started to operate separately through the controller. The power connection method of each electrical device is an existing mature technology, and the control circuit of the controller can be realized by simple programming by those skilled in the art. All are well-known technologies to those skilled in the art and will not be elaborated here.

[0050] The above has described the preferred embodiments of the present invention in detail. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in the art, various changes can be made without departing from the gist of the present invention.
