Description

Technical Field

[0001] This invention relates to the field of automatic candy conveying technology, specifically to an efficient automatic candy conveying device. Background Technology

[0002] After the candy production line continuously extrudes strip-shaped sugar blanks through the extrusion equipment, the candy strips need to be transported and cooled and solidified by a cooling conveyor before being connected to subsequent processes such as cutting and packaging. The multiple extruded candy strips are attached to the conveyor belt and then conveyed and processed on the production line by the conveyor belt.

[0003] For example, patent CN104310036B discloses a sugar conveying device for candies in strips, including a conveyor frame, a conveyor belt assembly, and a sprocket assembly. One end of the conveyor frame is provided with a sugar inlet, and the other end is provided with a sugar outlet. A sugar outlet component is installed at the sugar outlet. The sprocket assembly is installed on the conveyor frame, and the conveyor belt assembly is installed on the sprocket assembly. Its structure is simple and easy to use, effectively preventing deformation and scattering of candies during strip transportation, ensuring the quality of the candies, and improving production efficiency.

[0004] For example, patent CN113233223A discloses a multi-layer chain conveyor cooling mechanism for food templates, including a template for loading food, a cooling box, and a lower template transverse transmission mechanism mounted on a support and traversing the cooling box laterally. The mechanism is characterized by an upper template transverse transmission mechanism located above the lower template transverse transmission mechanism and transmitting the template in the same direction as it, also mounted on the support within the cooling box; and a multi-layer template synchronous chain lifting mechanism and a multi-layer template synchronous chain lowering mechanism arranged sequentially between the upper and lower template transverse transmission mechanisms along the template transmission direction. It also includes a refrigeration mechanism for generating a forward-backward cooling circulating airflow within the cooling box that passes through the multi-layer template synchronous chain lifting mechanism and the multi-layer template synchronous chain lowering mechanism. This mechanism provides good cooling for food while maintaining operational efficiency, making it a better choice as a cooling and conveying connection device in a food production line.

[0005] For example, patent CN211812455U discloses a cooling and conveying device for fried food, including a receiving device, a conveying device, a support, a cooling device, and a transmission device. The conveying device is fixedly installed above the support, the receiving device is installed above one end of the conveying device, and the discharging device and transmission device are installed at the other end of the conveying device. The cooling devices are evenly arranged below the conveying device. The transmission device includes a power unit, a conveyor belt, and a controller. The conveyor belt is installed on the conveying device through a main shaft and a secondary shaft, and the main shaft is connected to the power unit through a transmission wheel. By adopting a structural design in which the cooling device is located below the conveying device, the food can be cooled quickly. At the same time, the equipment space is effectively utilized, and the equipment structure is compact, with low manufacturing cost. During use, the cooling device is less likely to contaminate the food, thus affecting food safety. However, when the candy strips are not fully cured after extrusion, they are prone to sticking to the conveyor belt, affecting the discharging efficiency. Moreover, the candy strips stuck to the surface of the conveyor belt are easily broken after curing, reducing the quality of subsequent candy production. In addition, the bottom of the candy strip is attached to the surface of the conveyor belt, and its contact with cold air is limited, resulting in uneven cooling and curing of the candy strips and the formation of cooling blind spots.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing automatic candy conveying devices. Summary of the Invention

[0007] The purpose of this invention is to provide an efficient automatic candy conveying device to solve the problems mentioned in the background art, such as candy strips easily sticking to the conveyor belt before they are fully cured after extrusion, and the candy strips that stick to the surface of the conveyor belt are easily broken after curing, which affects the feeding efficiency and reduces the quality of subsequent candy production. In addition, the bottom of the candy strip is attached to the surface of the conveyor belt, and its contact with cold air is limited, resulting in uneven cooling and curing of the candy strip and the formation of cooling blind spots.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an efficient automatic candy conveying device, comprising a conveyor line installed in a candy production line, a cooling box installed on the outside of the conveyor line, and primary conveyor belts symmetrically installed at both ends along the conveying direction on the conveyor line, with two secondary conveyor belts arranged between the two primary conveyor belts. A fixed frame is fixedly installed on the inner wall of the cooling box, and a mesh plate for filtering and treating cooling gas is fixedly fixed on the upper end of the fixed frame; a lifting guide frame is longitudinally slidably connected through the mesh plate, and the lifting guide frame is arranged between the primary and secondary conveyor belts.

A straight steel wire is connected to the lifting guide frame to lift the candy strips on the conveyor line; a guiding mechanism for correcting the conveying position of the candy strips on the primary and secondary conveyor belts is provided on the fixed frame.

[0009] Preferably, a condenser and an evaporator are fixedly installed in the cooling box, with the condenser positioned above the conveyor line and the evaporator positioned below the conveyor line; an expansion valve is installed on the pipe connecting one side of the condenser and the evaporator, and a compressor is installed on the pipe connecting the other side of the condenser and the evaporator; a refrigeration fan is installed in the cooling box, positioned above the condenser, and a heat dissipation fan is installed in the cooling box, positioned above the evaporator.

[0010] Preferably, multiple arc-shaped steel wires are vertically fixed at equal intervals on the straight steel wire strip, and steel wires are fixedly connected between the arc-shaped steel wires on both sides of the secondary conveyor belt. The arc-shaped steel wires and steel wires are supported and arranged below the candy strip.

[0011] Preferably, the secondary conveyor belt has multiple embedded grooves at equal intervals, and the steel wires are embedded and stored in the embedded grooves.

[0012] Preferably, the guiding mechanism includes a guide slide fixedly installed on a fixed frame, a plurality of clamps slidably sleeved on the guide slide, the clamps being symmetrically distributed on both sides of the steel wire; a flexible pad is fixedly installed on the side of the clamps closest to the steel wire; a plurality of positioning frames are vertically fixed at equal intervals on the guide slide, two clamps located on both sides of the steel wire are slidably sleeved on the positioning frames, a fixing plate is fixedly installed on the positioning frame, and a positioning spring is elastically connected between the fixing plate and the positioning frame.

[0013] Preferably, a guide rail is fixed on the inner wall of the fixed frame, a crossbar is slidably mounted on the guide rail, a secondary transmission rod is rotatably connected to the crossbar, and the other end of the secondary transmission rod is rotatably connected to the clamping plate; a main transmission rod is rotatably connected below the crossbar, and the other end of the main transmission rod is rotatably connected to the lifting guide frame.

[0014] Preferably, the guiding mechanism is provided in three sets on the conveyor line, and arc-shaped columns are fixedly installed on the flexible pads in the latter two sets of guiding mechanisms; the arc-shaped columns on the flexible pads on both sides of the positioning frame are staggered vertically.

[0015] Preferably, the fixing frame is provided with an air blowing mechanism to increase the contact between the cold air inside the cooling box and the surface of the candy bar.

[0016] Preferably, the blowing mechanism includes multiple wind covers that are fixedly installed at equal intervals on a fixed frame. A wind blade assembly is rotatably installed in the wind cover. A gear is fixed on the wind blade assembly along the direction of the rotation axis, and a rack is meshed on the gear. A fixed rod is horizontally connected to the fixed frame, and the rack is slidably sleeved on the outside of the fixed rod.

[0017] Preferably, a connecting rod is fixed on the crossbar, the connecting rod slides through the fixed frame, and the other end of the connecting rod is fixedly connected to the rack.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In this efficient candy automatic conveying device, multiple parallel candy strips are conveyed together on the primary and secondary conveyor belts. During the conveying process, the candy strips are cooled inside the cooling box. During the conveying process, straight steel wires are intermittently controlled to push the candy strips upward, so that the bottom of the candy strips separates from the surface of the primary and secondary conveyor belts. This prevents the candy strips from sticking to the surface of the conveyor belts during the cooling and solidification process, maintains efficient conveying and feeding of the candy strips, and also increases the contact amount between the bottom of the candy strips and the cold air, thereby improving the uniformity of cooling of the candy strips.

[0019] Multiple curved steel wires are evenly spaced on the straight steel wire strip, and steel wires are connected between the curved steel wires on both sides of the secondary conveyor belt. During the process of the straight steel wire strip lifting the candy strip, the curved steel wire strip and steel wires support the candy strip from below, expanding the contact surface of the lifting candy strip and preventing the span of the lifting candy strip from being too large, which would cause the candy strip to bend and deform excessively.

[0020] The fixed frame is equipped with a guide mechanism to correct the position of the candy strips on the primary and secondary conveyor belts. During the process of lifting the candy strips, the guide mechanism can be linked to control the movement, so that the clamps in the guide mechanism move closer to the candy strips. The candy strips are pushed by the clamps on both sides, which can correct their position on the surface of the primary and secondary conveyor belts, and prevent the candy strips from shifting after being lifted, which would cause them to collide with each other during subsequent conveying.

[0021] Arc-shaped columns are fixed on the flexible pads of the two sets of guide mechanisms behind the conveyor line. The candy strips located in the two sets of guide mechanisms gradually cool and solidify. When the control clamp pushes and corrects the conveying position of the candy strips, the two sets of upper and lower staggered arc-shaped columns can push the solidified candy strips to rotate slightly, so that the bottom of the candy strips can be completely separated from the primary and secondary conveyor belts. Furthermore, the side-rotated candy strips can more effectively contact the cold air in the cooling box, improving the solidification effect.

[0022] As the lifting guide frame moves upward, it can drive the crossbar to move laterally. The crossbar drives the rack to move laterally synchronously through the connecting rod, so that the rack and gear mesh and drive the fan assembly to rotate, which accelerates the gas flow on the upper surface of the primary and secondary conveyor belts. This allows the bottom of the candy strip to better contact the cold air after it is lifted, further improving the cooling and solidification effect of the candy strip during the conveying process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1 and Figure 2 A condenser 201 and an evaporator 202 are fixedly installed in the cooling box 2. The condenser 201 is positioned above the conveyor line 1, and the evaporator 202 is positioned below the conveyor line 1. An expansion valve 203 is installed on the pipe connecting one side of the condenser 201 and the evaporator 202, and a compressor 204 is installed on the pipe connecting the other side of the condenser 201 and the evaporator 202. A refrigeration fan 206 is installed in the cooling box 2, which is positioned above the condenser 201, and a heat dissipation fan 205 is installed in the cooling box 2, which is positioned above the evaporator 202.

[0043] Please see Figures 4-7 , Figure 10 , Figure 12 and Figure 13 Multiple curved steel wires 81 are vertically fixed at equal intervals on the straight steel wire strip 8. Steel wires 82 are fixedly connected between the curved steel wires 81 on both sides of the secondary conveyor belt 4. The curved steel wires 81 and steel wires 82 are supported and arranged below the candy strip. Multiple embedded grooves 41 are opened at equal intervals on the secondary conveyor belt 4, and the steel wires 82 are embedded and stored in the embedded grooves 41.

[0044] Please see Figures 3-11The guiding mechanism includes a guide slide 9 fixedly mounted on a fixed frame 5. Multiple clamping plates 10 are slidably fitted onto the guide slide 9, symmetrically distributed on both sides of the steel wire 82. A flexible pad 11 is fixedly installed on the side of the clamping plate 10 closest to the steel wire 82. Multiple positioning frames 12 are vertically fixed at equal intervals on the guide slide 9. Two clamping plates 10 located on both sides of the steel wire 82 are slidably fitted onto the positioning frames 12. A fixing plate 13 is fixedly installed on the positioning frame 12, and a positioning spring 14 elastically connects the fixing plate 13 and the positioning frame 12. A guide rail 15 is fixedly mounted on the inner wall of the fixed frame 5. A crossbar 16 is slidably mounted laterally on the guide rail 15. A secondary transmission rod 17 is rotatably connected to the crossbar 16, and the other end of the secondary transmission rod 17 is rotatably connected to the clamping plate 10. A main transmission rod 18 is rotatably connected below the crossbar 16, and the other end of the main transmission rod 18 is rotatably connected to the lifting guide frame 7. Three sets of guiding mechanisms are provided on the conveyor line 1. Arc-shaped columns 19 are fixedly installed on the flexible pads 11 in the latter two sets of guiding mechanisms. The arc-shaped columns 19 on the flexible pads 11 on both sides of the positioning frame 12 are staggered vertically.

[0045] Conveyor line 1 is set between the candy extrusion equipment and the cutting equipment. After extrusion, the high-temperature candy strips are conveyed through conveyor line 1, cooled and solidified, and then conveyed to the cutting equipment for subsequent cutting processing. Multiple candy strips are oriented and attached to the surfaces of the primary conveyor belt 3 and the secondary conveyor belt 4 in parallel. During the conveying process, the condenser 201 in the cooling box 2 operates. The condenser 201, evaporator 202, expansion valve 203 and compressor 204 form a cooling system. The refrigeration fan 206 blows the low-temperature gas in the condenser 201 toward the conveyor line 1, thereby cooling the candy strips during the conveying process.

[0046] During the cooling and solidification process, the candy strips tend to stick to the surfaces of the primary conveyor belt 3 and the secondary conveyor belt 4. Therefore, during the conveying process, the intermittently operating cylinder 71 controls the lifting guide frame 7 to move upward. The lifting guide frame 7 drives the straight steel wire 8 to move upward synchronously. During the upward movement, the straight steel wire 8 makes partial contact with the candy strip and lifts the candy strip upward, so that the bottom of the candy strip separates from the surfaces of the primary conveyor belt 3 and the secondary conveyor belt 4. This effectively avoids the candy strip sticking to the surfaces of the primary conveyor belt 3 and the secondary conveyor belt 4 over a large area, thereby assisting the candy strip to be conveyed and discharged smoothly and efficiently.

[0047] During the process of lifting the candy strip, the arc-shaped steel wires 81 and 82 on the straight steel wire strip 8 support the bottom of the candy strip, which can increase the contact area of ​​lifting the candy strip and avoid the situation of local bending and deformation caused by excessive span of lifting the candy strip. The embedded groove 41 on the surface of the secondary conveyor belt 4 can not only accommodate the steel wires 82 in the downward state, but also transport some cold air to disperse below the candy strip, so that the candy strip cools and solidifies more evenly.

[0048] Simultaneously, as the lifting guide frame 7 moves upward, the two ends of the main drive rod 18 connected between the lifting guide frame 7 and the crossbar 16 rotate accordingly. The rotating main drive rod 18 pushes the crossbar 16 to engage with the outside of the guide rail 15 and move laterally. When the crossbar 16 moves laterally, the two ends of the auxiliary drive rod 17 connected between the crossbar 16 and the clamping plate 10 rotate accordingly. The rotating auxiliary drive rod 17 pushes the clamping plate 10 to engage with the guide slide 9 and slide. The clamping plates 10 located on both sides of the positioning frame 12 move relative to each other. The two sets of clamping plates 10 move closer to the candy strips. The flexible pads 11 on the clamping plates 10 contact the two sides of the candy strips, correcting the multiple candy strips located on the surfaces of the primary conveyor belt 3 and the secondary conveyor belt 4, and preventing the candy strips from being intermittently pushed up on the surfaces of the primary conveyor belt 3 and the secondary conveyor belt 4 and causing positional displacement.

[0049] During the directional conveying process on conveyor line 1, the candy strips gradually cool and solidify. The hardness of the candy strips solidified at the rear of conveyor line 1 increases. The two sets of guide mechanisms on conveyor line 1 have arc-shaped columns 19 fixed on their flexible pads 11. The arc-shaped columns 19 on the flexible pads 11 on both sides of the positioning frame 12 are staggered vertically. When the clamping plate 10 moves closer to the side of the candy strip, the two sets of staggered arc-shaped columns 19 contact the upper and lower right angle parts on both sides of the candy strip, which can push the solidified candy strip to rotate at a small angle. The rotating candy strip can completely separate from the surface of the primary conveyor belt 3 and the secondary conveyor belt 4. At the same time, the bottom of the rotating candy strip flips to the side, which can increase its contact with the cold air in the cooling box 2, thereby further expanding the cooling and solidification effect of the candy.

[0050] Example 2: Please refer to Figures 14-16 Based on Embodiment 1, a blowing mechanism is also disclosed, the specific structure of which is as follows: A blowing mechanism is provided on the fixed frame 5 to increase the contact amount between the cold air inside the cooling box 2 and the surface of the candy bar. The blowing mechanism includes multiple fan covers 20 that are fixedly installed at equal intervals on the fixed frame 5. A fan blade assembly 21 is rotatably installed in the fan cover 20. A gear 22 is fixed on the fan blade assembly 21 along the direction of rotation. A rack 23 is meshed on the gear 22. A fixed rod 24 is horizontally connected to the fixed frame 5. The rack 23 is slidably sleeved on the outside of the fixed rod 24. A connecting rod 25 is fixed on the crossbar 16. The connecting rod 25 slides through the fixed frame 5, and the other end of the connecting rod 25 is fixedly connected to the rack 23.

[0051] During the upward movement of the lifting guide frame 7, the horizontal bar 16 can be controlled to move laterally. The horizontal bar 16 in the middle of the fixed frame 5 is fixedly connected to the rack 23 through the connecting rod 25. During the lateral movement of the horizontal bar 16, the rack 23 can be driven to move synchronously through the connecting rod 25. The rack 23 is meshed with the gear 22. Under the meshing transmission, it can drive the fan blade assembly 21 to rotate. The fan blade assembly 21 is set on both sides of the upper surface of the primary conveyor belt 3 and the secondary conveyor belt 4. Its rotation can accelerate the gas flow on the surface of the primary conveyor belt 3 and the secondary conveyor belt 4, so that the cold air is evenly distributed on the surface of the primary conveyor belt 3 and the secondary conveyor belt 4, further increasing the contact amount between the bottom of the candy bar and the cold air, and improving the cooling and solidification effect of the candy bar.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
