Description

Technical Field

[0001] The present invention relates to the technical field of bread production, and in particular to an intelligent heat dissipation system of a bread production line and a working method thereof. Background Art

[0002] The fully automatic production process of bread includes mixing, rolling, proofing, baking, cooling and packaging. This process is generally carried out continuously on the production line. If the bread is cooled naturally after high-temperature baking, a very long conveyor belt is required. Therefore, most production lines currently use blowing to dissipate heat. Generally, a fan is set above the conveyor belt to blow directly on the bread being transported. If the wind force is small, the heat dissipation effect is poor. If the wind force is large, the wind pressure will easily deform the fluffy bread just after baking, affecting the appearance of the bread and thus affecting the yield rate. Summary of the invention

Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features.

[0029] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0030] The present invention provides an intelligent heat dissipation system for a bread production line. Figure 1 and 2 As shown, the heat dissipation system includes a turning conveyor 1, a linear conveyor 2, a turning device and a heat dissipation device 4. Both ends of the turning conveyor 1 are connected to the linear conveyor 2, and the two linear conveyors 2 are equipped with heat dissipation devices 4, and the heat dissipation devices 4 are used to cool the surface of the linear conveyor 2. The turning conveyor 1 can be a belt conveyor with a 180° turn or a belt conveyor with a 90° turn. In the present embodiment, a belt conveyor with a 180° turn is preferred. During operation, bread is loaded on one of the linear conveyors 2, so that the bread is transported to the turning conveyor 1, and then transported from the turning conveyor 1 to the other linear conveyor 2 for unloading. During the transportation of the bread on the two linear conveyors 2, the bread exchanges heat with the linear conveyors 2 to achieve heat dissipation and cooling.

[0031] As attached Figure 3 and 4As shown, the linear conveyor 2 includes a first frame 21, running rollers 22, transition rollers 23, a support plate 24 and a conveyor belt 25. A row of running rollers 22 is arranged above the first frame 21, and the two ends of the running rollers 22 can pass through the outside of the beams on both sides of the first frame 21, and the two ends of the running rollers 22 are respectively inserted into and fixed to the bearing seats fixed outside the beams to limit the rotation of the running rollers 22. Transition rollers 23 are arranged below each adjacent running roller 22 in the first frame 21, and the installation method of the transition rollers 23 is the same as that of the running rollers 22, and is connected to the bearing seats fixed outside the beams. The conveyor belt 25 passes over the top of each running roller 22 and the bottom of each transition roller 23 in turn, and then passes over the transmission rollers on both sides of the bottom of the first frame 21 to form a closed loop. The conveyor belt 25 can be driven to run by driving one of the transmission rollers to rotate by the motor. The first frame 21 is also provided with a supporting plate 24 between each two adjacent running rollers 22. The supporting plate 24 can be fixed by inserting bolts from the outside of the crossbeam of the first frame 21 inwardly and screwing the supporting plate 24 together, so that the supporting plate 24 is connected to the surface of the conveyor belt 25 outside the two adjacent running rollers 22, and the transition roller 23, the surfaces of the conveyor belt 25 on both sides above the transition roller 23 and the supporting plate 24 form a heat dissipation space 201. Preferably, the upper surface of the supporting plate 24 can be slightly lower than the top surface of the conveyor belt 25 outside the running roller 22 by 1 to 2 mm. This structure allows the soft bread to contact the conveyor belt 25 when the bread is placed on the linear conveyor 2, thereby moving forward under the operation of the conveyor belt 25. It is worth mentioning that Figure 3 The wheelbase between two adjacent running rollers 22 and the width of the supporting plate 24 shown can be customized as required, so as to design the corresponding linear conveyor 2 according to the bread size production requirements of the bread production line.

[0032] As attached Figure 6 As shown, the heat dissipation device 4 includes an air diffusion pipe 41, an air intake branch pipe 42, a cooling fan 43 and a refrigeration chamber 44. The cooling fan 43 is fixed in the refrigeration chamber 44, and a compressor 45, a condenser 46, an expansion valve and an evaporator 47 are connected in sequence in the refrigeration chamber 44. A heat dissipation hole is arranged on the top of the refrigeration chamber 44, and the heat dissipation hole corresponds to the condenser 46. The air inlet of the cooling fan 43 is connected to the refrigeration chamber 44. When working, the compressor 45 compresses the refrigerant into a high-temperature and high-pressure gas and sends it into the condenser 46. The condenser 46 releases the heat of the high-temperature and high-pressure refrigerant gas to the outdoor air through heat dissipation, and condenses itself into a high-pressure liquid. The high-pressure liquid is reduced in pressure by the expansion valve to become a low-temperature and low-pressure wet steam and enters the evaporator 47. The refrigerant in the evaporator 47 absorbs the heat in the refrigeration chamber 44 to reduce the air temperature in the refrigeration chamber 44. At the same time, it evaporates itself into a gaseous refrigerant and is sucked into the compressor 45 again to form a cycle.

[0033] Please refer to the attached Figure 3 , 47, each heat dissipation space 201 is equipped with an air diffusion pipe 41, and exhaust holes are set on both sides of the air diffusion pipe 41. Each air diffusion pipe 41 is connected to the cooling fan 43 through an air intake branch pipe 42. The connection method can be that the air intake branch pipe 42 is fixed on one side of the first frame 21, and one end of each air diffusion pipe 41 is connected to the air intake branch pipe 42, and the other end of each air diffusion pipe 41 is closed, thereby forming a connecting pipeline for each air diffusion pipe 41 in parallel, one end of the air intake branch pipe 42 is connected to the air outlet of the cooling fan 43 through an adapted elbow, and the other end of the air intake branch pipe 42 is closed, so that the cooling fan 43 can blow the cold air in the refrigeration chamber 44 into each air diffusion pipe 41, and then blow it into each heat dissipation space 201 through the air diffusion holes on both sides of each air diffusion pipe 41, so that the conveyor belt 25 and the supporting plate 24 forming the heat dissipation space 201 are cooled and maintained at a low temperature. It is worth mentioning that as the conveyor belt 25 runs, the surface of the conveyor belt 25 that forms the heat dissipation space 201 is turned upward after running onto the running roller 22, so that the bread being conveyed directly contacts the conveyor belt 25 that is cooled, which is beneficial to improving the efficiency of cooling and dissipating the heat of the bread.

[0034] Alternatively, the air diffuser 41 and the air intake branch 42 may be connected in such a manner that the two ends of the air diffuser 41 pass through the two sides of the first rack 21 and are connected to the U-shaped tubes, and the two ends of each air diffuser 41 are connected to the U-shaped tubes, and the U-shaped tube at one end of the air diffuser 41 is connected to a previously arranged air diffuser 41, and the U-shaped tube at the other end of the air diffuser 41 is connected to the next arranged air diffuser 41, so that the air diffuser 41 fixed in the first rack 21 forms a series structure of continuous S-shaped connection through the connection of the U-shaped tubes, and at the same time, one of the first and last air diffuser 41 of each air diffuser 41 arranged in the first rack 21 is connected to one end of the air intake branch 42 at the other end relative to the U-shaped tube, and the other end of the air intake branch 42 is connected to the air outlet of the cooling fan 43. The cooling fan 43 can blow the cold air in the refrigeration chamber 44 into each air diffuser 41.

[0035] Preferably, the present invention can also be configured with a control system, which is used to control the operation of the actuators included in the linear conveyor 2 and the curved conveyor 1. A temperature sensor can also be configured in the refrigeration chamber 44, which senses the temperature in the refrigeration chamber 44 in real time and sends the temperature signal to the control system, and the control system sends the received temperature signal to the screen on the control cabinet for display. Preferably, the screen of the control cabinet can be a touch control screen, and the compressor 45, condenser 46, expansion valve and evaporator 47 can be controlled by operating on the screen of the control cabinet to adjust the cold air temperature in the refrigeration chamber 44 and control the cooling fan 43 to adjust the air pressure entering each heat dissipation space 201, thereby forming an intelligent operation control of the heat dissipation system.

[0036] Continue to refer to the attached Figure 2The flipping device includes a flip plate 31, an inner limit rod 32, an outer limit rod 33 and a flip cam 34. The flip plate 31 is fixed on the straight conveyor 2 connected to the starting end of the curved conveyor 1. Figure 8 The flip plate 31 is a curved plate structure with 90-degree twists at both ends of the flat plate, so that the two ends of the flip plate 31 form a horizontal end 311 and a vertical end 312 that are perpendicular to each other. The horizontal end 311 of the flip plate 31 is connected to a supporting plate 24 in parallel, and the vertical end 312 of the flip plate 31 is vertical relative to the supporting plate 24, so that the surface of the flip plate 31 forms a flip curved surface that transitions from a horizontal surface to a vertical surface along the conveying direction of the linear conveyor 2. Fig. 9 The flipping device further includes a side stop mechanism 35, which is fixed on the other side of the flip plate 31 opposite to the vertical end. Specifically, the side stop mechanism 35 can be fixed on the crossbeam of the first frame 21, so that the plane of the side stop mechanism 35 is vertical relative to the first frame 21. When the bread is transported to the flip plate 31, the front end of the bread moves upward along the horizontal end of the flip plate 31, and under the guidance of the flip plate 31, it flips from a flat placement state to the outside of the first frame 21 to a vertical state, and is blocked by the side stop mechanism 35. It can be seen that the structure of the flip plate 31 arranged on the linear conveyor 2 can automatically flip the bread being transported by 90 degrees, and then transport it to the curved conveyor 1. Preferably, the horizontal end of the flip plate 31 is bent downward to form an embedded portion 311, which is sleeved on the edge of the support plate 24, and the lower end of the embedded portion 311 extends below the surface of the conveyor belt 25 on the running roller 22, so that the bread being transported can be smoothly transferred to the flip plate 31 without being blocked by the horizontal end.

[0037] Continue to refer to the attached Fig. 9 The side blocking mechanism 35 is a side conveyor, which is vertically fixed on the first frame 21, and the conveying surface of the side conveyor facing the flip plate 31 is the blocking surface. The conveying surface of the side conveyor is the straight conveyor 2 running in the direction of the turning conveyor 1. This method can guide and drive the bread that has flipped over on the flip plate 31 and fallen toward the blocking surface to continue to be conveyed to the turning conveyor 1.

[0038] Continue to refer to the attached Figure 4 A guide plate 26 is provided on the linear conveyor 2 connected to the starting end of the curved conveyor 1. The guide plate 26 is provided on the first frame 21 and is located on the other side of the flip plate 31 relative to the side stop mechanism 35. The blocking surfaces of the guide plate 26 and the side stop mechanism 35 are inclined, and the distance between the guide plate 26 and the first frame 21 near the flip plate 31 gradually narrows, thereby guiding the bread transported on the linear conveyor 2 to the horizontal end of the flip plate 31, so that the bread guided by the guide plate 26 can move to the flip plate 31 along the side of the guide plate 26. Further, referring to the attached Figure 5A connecting rod 27 is also provided on the back of the guide plate 26. An adjustment seat 28 is fixed to the other end of the first frame 21 opposite to the side stop mechanism 35. The adjustment seat 28 has an adjustment hole. One end of the connecting rod 27 passes through the adjustment hole. A notch is provided above the adjustment seat 28 and penetrates the adjustment hole. The adjustment seat 28 is spirally connected to a first bolt 281 from outside to inside. The first bolt 281 spirally passes through the notch to tighten the adjustment hole so as to fix one end of the connecting rod 27 on the first frame 21.

[0039] As attached Fig.11 and 12 As shown, the other end of the connecting rod 27 is pivotally connected to the connecting member 29, and a C-shaped slide groove 261 is provided on the back of the guide plate 26. The connecting member 29 is adapted to be embedded in the slide groove 261 and then slidably fixed. The fixing method can be that the connecting member 29 is penetrated from top to bottom with a second bolt 291, and a strip-shaped adjustment groove is provided above the slide groove 261 on the back of the guide plate 26. The second bolt 291 passes through the adjustment groove and then is screwed and fastened to the connecting member 29 to fix the guide plate 26 relative to the first frame 21. When it is necessary to adjust the position of the guide plate 26 relative to the side stop mechanism 35, the first bolt 281 and the second bolt 291 are loosened and then the position of the connecting rod 27 relative to the adjustment seat 28 and the position of the adjusting connecting member relative to the guide plate 26 are adjusted, so that the position of the guide plate 26 is adjusted according to the size of the bread to be produced, so that the bread can be transported from between the guide plate 26 and the side stop mechanism 35 to the flip plate 31.

[0040] In addition, the vertical end of the flip plate 31 and the end of the guide plate 26 are hinged through a hinge connection. Combined with the structure in which the embedded portion 311 of the flip plate 31 is sleeved on the edge of the supporting plate 24, when the guide plate 26 is adjusted and moved, the flip plate 31 can be driven to move parallel to the width direction of the linear conveyor 2, without the need to adjust the position of the flip plate 31 separately, which is more convenient.

[0041] As attached Figure 2 , 4 As shown in Figures 9 and 10, the inner limit rod 32 and the outer limit rod 33 are both fixed above the conveying surface of the curved conveyor 1, and the inner limit rod 32 and the outer limit rod 33 are respectively connected to the two sides outside the flip plate 31. This structure allows the bread that has been flipped 90° on the flip plate 31 to be transported to the curved conveyor 1 and then be restricted between the inner limit rod 32 and the outer limit rod 33, so that the flipped bread is kept vertically conveyed. During this conveying process, the bread can only lean against the inner limit rod 32 or the outer limit rod 33. Therefore, in this embodiment, the inner limit rod 32 is also longer than the outer limit rod 33, and the outer limit rod 33 gradually extends downward in the direction away from the flip plate 31. When the bread leans against the outer limit rod 33 to be conveyed, since the outer limit rod 33 extends downward, the bread gradually loses its support from above and flips down to be placed on the conveying surface of the curved conveyor 1, forming another flip of 90°.

[0042] Please refer to the attached Fig.10 The flipping device further includes a rotating motor (not shown in the drawings). The central fixing mounting plate 11 of the curved conveyor 1 is fixed to the bottom of the mounting plate 11. The output shaft of the rotating motor is connected to the flip cam 34. The flip cam 34 can be driven to rotate by the rotating motor, so that the flip cam 34 arranged on the side of the curved conveyor 1 close to the inner limit rod 32 rotates, and the end of the flip cam 34 flips to between the inner limit rod 32 and the outer limit rod 33. When the bread is conveyed against the inner limit rod 32 or is conveyed between the inner limit rod 32 and the outer limit rod 33, when the bread moves to the tail section of the inner limit rod 32, the rotating flip cam 34 pushes the top of the bread downward, and when the bread is pushed to the bottom of the side of the bread facing away from the inner limit rod 32 and is blocked by the downwardly extending end of the outer limit rod 33, the bread can be flipped down to be placed on the conveying surface of the curved conveyor 1, forming another flip of 90°, completing the 180° flipping of the bread during the conveying process. It can be seen that the structure of the above inner limit rod 32, outer limit rod 33 and flip cam 34 can make the flip plate 31 flip 90° and then flip it again 90° in the same flip direction to complete the 180° flipping of the bread during the conveying process, so that when the bread is transported to another linear conveyor 2 through the curved conveyor 1, the other side of the bread is attached to the linear conveyor 2 for cooling and heat dissipation.

[0043] In addition, a plurality of strip-shaped mounting holes 111 are arranged on the surface of the mounting plate 11, and the output shaft of the rotating motor passes through the middle mounting hole 111. The fixing bolts 12 for fixing the rotating motor pass through the mounting holes 111 on both sides and are screwed into the rotating motor, thereby fixing the rotating motor. When it is necessary to adjust the position of the flip cam 34 relative to the inner limit rod 32, the position of the rotating motor can be moved along the mounting hole 111 by loosening the fixing bolts, thereby adjusting the position of the flip cam 34 relative to the inner limit rod 32, so that the flip cam 34 can adjust its position relative to the inner limit rod 32 according to the different thicknesses of the bread, thereby preventing the flip cam 34 from failing to reach the bread transported between the inner limit rod 32 and the outer limit rod 33.

[0044] Continue to refer to the attached Figure 4One end of the inner limit rod 32 is fixed to the end face of the vertical end of the flip plate 31, and the other end of the inner limit rod 32 is fixed to the support frame 321. The support frame 321 is connected to the connecting plate 36 fixed to the side of the first frame 21, and the support frame 321 is restricted on the connecting plate 36 to move linearly relative to the first frame 21 and then fixed. The fixing method can be that a strip hole 361 is set on the connecting plate 36, and the length direction of the strip hole 361 is parallel to the width direction of the linear conveyor 2. The bottom of the support frame 321 is fixed with a screw rod. After the screw rod passes through the strip hole 361, a nut is screwed on the bottom of the connecting plate 36 to tighten and fix it. When adjustment is required, the nut can be loosened. This structure makes it very convenient to drive the inner limit rod 32 to move at the same time when the guide plate 26 is adjusted to drive the flip plate 31 to move.

[0045] The present invention provides a working method of the above heat dissipation system, and the working method is as follows: The heat dissipation device 4 configured for the two linear conveyors 2 starts to work, so that the cooling fan 43 conveys cold air to each air inlet branch pipe 42, and blows the cold air into each heat dissipation space 201 of the linear conveyor 2 through each air diffusion pipe 41, so that the temperature of the conveyor belt 25 and the supporting plate 24 forming the heat dissipation space 201 drops to a low temperature state; Place the breads one by one on the straight conveyor 2 connected to the starting end of the curved conveyor 1, so that one side of the bread is attached to the straight conveyor 2 and is in contact with the low-temperature support plate 24 and the conveyor belt 25 while being conveyed, so as to form heat exchange during the conveying process, so that one side of the bread dissipates heat by cooling; When the bread passes through the surface of the turning plate 31, it is guided to turn sideways by 90°, and then turns sideways by 90° again when passing through the inner limit rod 32 and the outer limit rod 33, so that the bread is turned over on the curved conveyor 1, with the other side facing downwards. When the bread is conveyed to another linear conveyor 2, the other side of the bread (i.e., the side facing downward after being turned over) is attached to the linear conveyor 2 and is contacted with the support plate 24 and the conveyor belt 25 in a low-temperature state while being conveyed, thereby forming heat exchange during the conveyance process, so that the other side of the bread dissipates heat by cooling.

[0046] It can be known from the above working method that when the present invention is working, the flipping device drives the bread to be turned over on the curved conveyor 1, so that one side of the bread is conveyed on one of the linear conveyors 2 facing down, and then the other side of the bread is conveyed on the other linear conveyor 2 facing down, forming a mode in which the two sides of the bread are respectively attached to the two linear conveyors 2 for conveyance. During this conveying process, the two linear conveyors 2 both use the heat dissipation device 4 to cool the conveyor belt 25 and the support plate 24, so that the two sides of the bread in the conveying process are cooled by cooling respectively. Compared with the blowing method, this contact heat dissipation method is not easy to damage the appearance of the bread, and can enable the bread to maintain a complete appearance during the heat dissipation process, which is beneficial to improving the yield of bread production.

[0047] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
