Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent suspension conveying systems, and in particular to an automatic cooling and conveying device for cold storage plates. BACKGROUND

[0002] As a core component of cold chain logistics and refrigeration facilities, the heat treatment and cooling process of cold storage plates in the production process is crucial to product quality. Currently, the industry generally uses heat treatment processes to improve the mechanical properties and durability of cold storage plates, but the cooling process after heat treatment still has problems such as low efficiency and high manual intervention. With the development of automation technology, the traditional manual handling and natural cooling method has been difficult to meet the needs of large-scale industrial production, and there is an urgent need to develop an efficient and stable automatic cooling and conveying system.

[0003] Currently, there are two main ways to cool cold storage plates: one is to manually operate a crane or forklift to transfer hot plates to an open-air site for natural cooling, which is labor-intensive and has safety hazards; the other is to use a simple roller conveyor combined with a spray cooling system, which achieves semi-automation, but the spray system can cause oxidation on the surface of the plates and consume a large amount of water. Therefore, the existing technology cannot seamlessly connect the heat treatment and cooling processes, and is prone to damage to the cold storage plates, which restricts the overall automation level of the production line.

[0014] By adopting the above technical solution, the adjusting assembly utilizes the gravity of the counterweight and the attitude change of the support frame at different positions on the chain transmission path to automatically adjust the position of the abutting plate. At the feeding position, when the support frame is in a horizontal state, the force of the counterweight makes the abutting plate move upward against the elastic force of the first elastic member, so that the abutting plate and the bottom wall of the clamping frame are in a spaced arrangement, providing a spacious passage for the cold storage plate to enter, and realizing smooth feeding without contact. During the rotation of the support frame from the horizontal state to the vertical state, the force of the counterweight on the abutting plate is smoothly reduced, so that the first elastic member can slowly push the abutting plate to gradually abut against the cold storage plate, avoiding impact damage, and the abutting plate abutting against the cold storage plate prevents the cold storage plate from deflecting or toppling during the transfer process, realizing protection of the cold storage plate during the transfer process. At the discharging position, during the rotation of the support frame from the vertical state to the horizontal state, the cold storage plate can be lapped on the abutting plate and make the abutting plate slowly move downward, and then cooperate with the discharging action, the cold storage plate can be removed without damage, thereby realizing automatic protection of the cold storage plate during the transfer process, and the protection process does not easily affect the feeding and discharging process of the cold storage plate.

[0022] By adopting the above technical scheme, the cooling air flow provided by the air supply assembly can be directly delivered to the interiors of the support frame and the abutting plate, and accurately blown to the contact areas of the cold storage plates and the support frame and the abutting plate from the air exhaust holes, so that local hot spots are actively eliminated, thereby ensuring the uniformity of the overall cooling speed of the cold storage plates, preventing warping deformation caused by uneven cooling, and ensuring the product quality of the cold storage plates.

[0023] Optionally, the air supply assembly comprises a fan, an air supply pipe, a second elastic member and an intermittent connecting component, the air outlet side of the fan is in communication with the air supply pipe, the opening of the air supply pipe faces the opening of the end of the support frame and the abutting plate, the air supply pipe is slidingly arranged, the second elastic member is connected with the air supply pipe, and the intermittent connecting component is connected between the support frame and the air supply pipe, so that the second elastic member drives the air supply pipe to reset after the support frame pushes the air supply pipe to move a distance.

DETAILED DESCRIPTION

[0030] The following Figures 1-13 The application is further described in detail.

[0031] Embodiment 1 The embodiment of the application discloses an automatic cooling and conveying device for cold storage plates 14. Referring to Figure 1 , the automatic cooling and conveying device for cold storage plates 14 comprises a feeding mechanism 1, a transfer mechanism 2 and a discharging mechanism 3. The feeding mechanism 1 is used to convey the cold storage plates 14 that have just completed heat treatment and are in a high-temperature state to the transfer mechanism 2; the transfer mechanism 2 is used to bear the cold storage plates 14 and convey the cold storage plates 14 from one side close to the feeding mechanism 1 to one side close to the discharging mechanism 3, and the cooling process of the cold storage plates 14 can be carried out at the same time in the conveying process; and the discharging mechanism 3 is used to take out the cold storage plates 14 that have been cooled to a target temperature from the transfer mechanism 2.

[0032] Referring to Figure 2The transfer mechanism 2 comprises a rack 21, a closed-loop chain transmission assembly 22 arranged on the rack 21, and a plurality of loading racks 23 fixed on the chain transmission assembly 22. The chain transmission assembly 22 comprises two sprockets 221 and a chain 222 arranged between the two sprockets 221, and the axes of the sprockets 221 are arranged horizontally. One of the sprockets 221 is connected with the output shaft of a speed reducer motor, so that the sprocket 221 can be driven to rotate, thereby driving the chain 222 to run. In the embodiment, the chain 222 is arranged in one and located in the middle of the loading racks 23. The rack 21 is provided with support plates 211 on both sides of the chain 222. The support plates 211 are fixedly installed on the rack 21 and located between the loading racks 23 on the upper and lower sides, so that the support plates 211 can support the loading racks 23, thereby improving the carrying capacity and stability of the device. In other embodiments, the chain 222 and the sprockets 221 can also be arranged in multiple groups in parallel and at intervals according to needs.

[0033] The loading racks 23 are arranged in multiple and uniformly spaced along the length direction of the chain 222, so that the chain transmission assembly 22 can drive the loading racks 23 to move circularly between the feeding mechanism 1 and the discharging mechanism 3. The loading rack 23 comprises a horizontal support rod 231 and a plurality of support frames 232 fixed on the side of the support rod 231 away from the chain 222. The support rod 231 is arranged along the axis direction of the sprocket 221, and the support rod 231 is fixedly connected with the chain 222 of the chain transmission assembly 22, so that the support rod 231 can move synchronously with the chain 222. The plurality of support frames 232 are arranged in multiple and uniformly spaced along the length direction of the support rod 231, and the end of the support frame 232 away from the support rod 231 is arranged in an open manner, so as to facilitate the entry and exit of the cold storage plates 14. Thus, the cold storage plates 14 are supported by the plurality of support frames 232, which can improve the stability of the cold storage plates 14 in the transfer mechanism 2.

[0034] Referring to Figure 3 and Figure 4 The feeding mechanism 1 and the discharging mechanism 3 have the same structure, and each comprises a lifting assembly 11 and a belt transmission assembly 12. The lifting assembly 11 comprises a lifting frame 111 and a lifting cylinder 112. The piston rod of the lifting cylinder 112 is vertically upward, and the lifting frame 111 is fixedly connected to the end of the piston rod of the lifting cylinder 112, so that the lifting frame 111 can vertically slide. In other embodiments, the lifting frame 111 can also be driven to lift by a servo cylinder, or the lifting of the lifting frame 111 in the vertical direction can be realized by arranging a transmission structure of a motor, a gear and a rack.

[0035] The belt transmission assembly 12 is arranged on the lifting frame 111 and can be lifted together with the lifting frame 111. The belt transmission assembly 12 is arranged in multiple groups and is uniformly spaced along the length direction of the lifting frame 111. Each group of the belt transmission assembly 12 is horizontally arranged and perpendicular to the length direction of the lifting frame 111. The belt transmission assembly 12 includes two pulleys 121 and a conveying belt 122 arranged between the two pulleys 121. The top surface of the conveying belt 122 is used to abut against the refrigeration plate 14. The belt transmission assembly 12 further includes a motor. The output shaft of the motor is coaxially connected with one of the pulleys 121, so as to drive the pulley 121 to rotate, thereby driving the conveying belt 122 to operate. The lifting frame 111 is further fixedly provided with a bearing plate 123. The bearing plate 123 is located on the inner side of the conveying belt 122 and is used to support the conveying belt 122, thereby better driving the refrigeration plate 14 placed on the top of the conveying belt 122 to move.

[0036] With reference to Figure 4 The conveying device in the present application is provided with conveying mechanisms 10 on the feeding side and the discharging side. The conveying mechanism 10 includes multiple parallel and spaced conveying rollers 101 arranged along the length direction of the belt transmission assembly 12. The conveying roller 101 is rotationally arranged. The end of each conveying roller 101 is provided with a transmission sprocket. The outer side of the transmission sprocket is provided with a transmission chain. The transmission sprocket is connected with the motor, so as to synchronously drive multiple conveying rollers 101 to rotate. The top of the conveying roller 101 is used to support the refrigeration plate 14. Thus, the refrigeration plate 14 can be conveyed to the feeding mechanism 1 along the conveying roller 101 after being subjected to heat treatment.

[0037] It should be noted that the belt transmission assembly 12 and the conveying roller 101 are arranged in a staggered manner. The length of the belt transmission assembly 12 is greater than the length of the conveying roller 101. One end of the belt transmission assembly 12 extends to the side close to the transfer mechanism 2. The horizontally arranged support frame 232 at the end of the transfer mechanism 2 is arranged in a staggered manner with the belt transmission assembly 12, so as to avoid interference between the components during work.

[0038] With reference to Figure 1The cold storage plate 14 moved to the feeding mechanism 1 is placed on the top surface of the conveying roller 101, and the top of the belt driving assembly 12 is located below the conveying roller 101. Then the lifting assembly 11 drives the belt driving assembly 12 to move upward, the top of the belt driving assembly 12 lifts the cold storage plate 14 upward, and the cold storage plate 14 is supported by the belt driving assembly 12; at this time, the support frame 232 on the side of the transfer mechanism 2 close to the feeding mechanism 1 is in a horizontal state. Then the belt driving assembly 12 operates to horizontally move the cold storage plate 14 to the inside of the support frame 232, at this time the cold storage plate 14 is suspended inside the support frame 232, so that the surface of the cold storage plate 14 can be prevented from being scratched during the conveying process; then the lifting assembly 11 drives the belt driving assembly 12 to move downward, so that the cold storage plate 14 moves downward, until the bottom wall of the cold storage plate 14 abuts against the support frame 232, thereby completing the feeding process of the cold storage plate 14. Then the chain driving assembly 22 operates, so that the support frame 232 loaded with the cold storage plate 14 moves with the chain driving assembly 22, and the subsequent natural cooling process is performed.

[0039] The working principle of the discharging mechanism 3 is the same as that of the feeding mechanism 1. When discharging, the belt driving assembly 12 first moves upward and lifts the cold storage plate 14 in the support frame 232 upward, then the belt driving assembly 12 horizontally moves the cold storage plate 14 to the outside of the support frame 232, then the belt driving assembly 12 moves downward and drives the cold storage plate 14 to move downward, until the bottom wall of the cold storage plate 14 abuts against the top wall of the conveying roller 101 at the discharging mechanism 3, thereby completing the discharging process of the cold storage plate 14. Then the conveying roller 101 rotates to convey the cooled cold storage plate 14 backward.

[0040] By controlling the lifting assembly 11, the height of the belt driving assembly 12 can be accurately matched with the height of the support frame 232 currently located at the feeding station or the discharging station, so that the cold storage plate 14 can be smoothly transferred into or moved out. This set of mechanism combination guarantees the automatic connection and smooth operation of the feeding and discharging processes.

[0041] The implementation principle of the embodiment 1 is that the lifting assembly 11 of the feeding mechanism 1 drives the belt transmission assembly 12 to move upward, and a cold storage plate 14 after heat treatment is lifted upward by the belt transmission assembly 12 until the cold storage plate 14 is higher than the bottom wall of the support frame 232 in the empty state; then the belt transmission assembly 12 moves the cold storage plate 14 horizontally into the support frame 232, and the belt transmission assembly 12 is reset by moving downward. Subsequently, the chain transmission assembly 22 is started, and the feeding rack 23 starts to move in a cycle, and the cold storage plate 14 can be naturally cooled and cooled down in the movement of the feeding rack 23. When the feeding rack 23 moves to the discharging station, the cold storage plate 14 has been cooled down, and at this time, the lifting assembly 11 of the discharging mechanism 3 also lifts the belt transmission assembly 12 to the corresponding height, the belt transmission assembly 12 lifts the cold storage plate 14 upward, and then the cooled cold storage plate 14 is moved out of the support frame 232, and then the belt transmission assembly 12 moves downward again, so that the cold storage plate 14 falls onto the conveying roller 101 at the discharging mechanism 3, and a complete automatic cooling and conveying process is completed. The structure realizes the continuity and automation of the production process, which helps to improve the production efficiency.

[0042] Embodiment 2 With reference to Figure 5 and Figure 6 The difference between the embodiment and the embodiment 1 is that, in the embodiment, in order to stably fix the cold storage plate 14 during conveying, a limiting assembly 4 is arranged inside each support frame 232. For the convenience of description, the support frame 232 includes a connecting plate 2321 fixedly connected to the chain 222, and a first bearing arm 2322 and a second bearing arm 2323 fixedly arranged at both ends of the connecting plate 2321, and the first bearing arm 2322 and the second bearing arm 2323 are arranged in parallel and at intervals.

[0043] The limiting assembly 4 includes an abutting plate 41, a guide rod 42 and a first elastic member 43. The abutting plate 41 is located on the inner side of the support frame 232, and the abutting plate 41 is arranged along the length direction of the support frame 232, that is, the length direction of the first bearing arm 2322. The guide rod 42 is fixedly connected to the abutting plate 41 perpendicularly, and the guide rod 42 is arranged along the width direction of the support frame 232; the guide rod 42 is arranged in multiple and arranged in parallel and at intervals along the length direction of the support frame 232. The second bearing arm 2323 is provided with a through hole, and the guide rod 42 is slidably arranged in the through hole, so that the abutting plate 41 is slidably arranged. The first elastic member 43 is a spring, and the first elastic member 43 is connected between the abutting plate 41 and the second bearing arm 2323. Therefore, the arrangement of the abutting plate 41 can limit the movement and rotation space of the cold storage plate 14 conveyed into the support frame 232, so as to avoid the cold storage plate 14 from being deflected at a large angle during the operation of the chain transmission assembly 22, thereby reducing the possibility of scratching the cold storage plate 14 during the transfer process.

[0044] The abutting plate 41 and the first bearing arm 2322 are provided with abutting blocks 5 on the side close to each other, the abutting blocks 5 are arranged uniformly and spaced apart along the length direction of the abutting plate 41 or the first bearing arm 2322, the abutting blocks 5 are semicircular blocks, and the arc surfaces of the abutting blocks 5 on the abutting plate 41 and the first bearing arm 2322 face the side close to each other, so that the abutting blocks 5 abut against the cold storage plate 14, and the close fit between the support structure and the cold storage plate 14 can be avoided to affect the local cooling of the cold storage plate 14. The abutting blocks 5 are made of elastic material, or a flexible pad is arranged on the surface of the abutting blocks 5, so as to avoid scratching the surface of the cold storage plate 14 by the abutting blocks 5. In other embodiments, the abutting blocks 5 can also be rectangular blocks, and a rounded corner is arranged at the end of the abutting blocks 5 for contact with the cold storage plate 14 to prevent scratching.

[0045] With reference to Figure 7 Further, the adjusting assembly 6 is arranged on each support frame 232, and the adjusting assembly 6 comprises a counterweight 61 and a connecting component 62. The support frame 232 is provided with a guide groove 2324, and the guide groove 2324 is arranged along the width direction of the support frame 232, that is, the guide groove 2324 is arranged along the length direction of the connecting plate 2321. The counterweight 61 is slidably connected to the guide groove 2324 along the axis direction of the guide groove 2324. The connecting component 62 comprises a connecting rope 621 and a reversing wheel 622. The reversing wheel 622 is rotationally connected to the second bearing arm 2323, and the connecting rope 621 is wound around the reversing wheel 622. The connecting rope 621 is a flexible rope body and has no elasticity. One end of the connecting rope 621 is fixedly connected to the abutting plate 41, and the other end of the connecting rope 621 is fixedly connected to the counterweight 61.

[0046] With reference to Figure 7 For the support frame 232 in the horizontal state on one side of the feeding mechanism 1, without considering the connecting component 62, since the first elastic member 43 is in a compressed state, the abutting plate 41 will abut tightly on the first bearing arm 2322 in the initial state. In the present application, the connecting component 62 is arranged, so that in the initial state, the counterweight 61 will be subjected to the downward gravity, and the weight of the counterweight 61 will generate an upward pulling force on the abutting plate 41 through the connecting rope 621, so that the abutting plate 41 moves upward, and a part of gap is reserved between the bottom end of the abutting plate 41 and the first bearing arm 2322, so that the cold storage plate 14 in the conveying mechanism 10 on one side of the feeding mechanism 1 enters the support frame 232.

[0047] When the cold storage plate 14 enters the support frame 232, it loses the support of the belt transmission assembly 12 and falls on the first bearing arm 2322, which supports the cold storage plate 14. As the chain transmission assembly 22 operates, the support frame 232 with the cold storage plate 14 rotates to an inclined state and then to a vertical state with the opening facing upward. During the rotation of the support frame 232, the guide groove 2324 rotates with the support frame 232. Since the counterweight 61 is slidingly arranged in the guide groove 2324, the pulling force of the connecting rope 621 on the abutting plate 41 decreases as the support frame 232 rotates. After the pulling force decreases, the first elastic member 43 moves the abutting plate 41 to the side close to the first bearing arm 2322 and the cold storage plate 14 until the abutting plate 41 abuts against the cold storage plate 14. Referring to Figure 8 When the opening of the support frame 232 faces upward, the abutting plate 41 abuts against the cold storage plate 14 on the first bearing arm 2322. The direction of the gravity of the counterweight 61 is perpendicular to the direction of the connecting rope 621, so the counterweight 61 cannot exert a force on the abutting plate 41 at this time, thereby ensuring the stable abutment of the abutting plate 41 on the cold storage plate 14 to improve the stability of the cold storage plate 14 during movement in the transfer mechanism 2.

[0048] Referring to Figure 5 As the chain transmission assembly 22 operates, when the support frame 232 with the cold storage plate 14 moves to the end close to the unloading mechanism 3, the support frame 232 starts to deflect from the state with the opening facing upward. During the downward rotation of the support frame 232, the abutting plate 41 always supports one side of the cold storage plate 14, so the cold storage plate 14 deflects with the abutting plate 41. When the support frame 232 rotates to a horizontal state with the opening facing right, the cold storage plate 14 is completely overlapped on the top surface of the abutting plate 41. Under the action of the self-weight of the cold storage plate 14 and the abutting plate 41, the first elastic member 43 is compressed. At this time, the top wall of the cold storage plate 14 is spaced apart from the first bearing arm 2322. Then the belt transmission assembly 12 at the unloading mechanism 3 lifts the cold storage plate 14 upward and moves it horizontally outward to move the cold storage plate 14 in the support frame 232 outward. During the outward movement of the cold storage plate 14, the first elastic member 43 is still in the compressed state due to the self-weight of the abutting plate 41. Therefore, even after the belt transmission assembly 12 lifts the cold storage plate 14 upward, the abutting plate 41 and the first bearing arm 2322 are still in a spaced apart state, so that the cold storage plate 14 can be prevented from being scratched by contacting the first bearing arm 2322, the second bearing arm 2323, or the abutting plate 41 during the outward movement of the cold storage plate 14.

[0049] After the unloading process of the cold storage plate 14 is completed, the support frame 232 continues to operate with the chain transmission assembly 22, and the support frame 232 will be rotated to a state with the opening facing downward; when the support frame 232 moves to the end close to the feeding mechanism 1 again, the weight of the counterweight 61 will again exert an upward pulling force on the abutting plate 41 through the connecting rope 621, so that the abutting plate 41 is in a state of being spaced apart from the first bearing wall, so as to move the new cold storage plate 14 to the inside of this support frame 232.

[0050] The working process of the adjusting assembly 6 fully utilizes the gravity of the counterweight 61 and the abutting plate 41, so that the position of the abutting plate 41 can be adaptively adjusted according to the position of the support frame 232. This gradual force exertion method avoids sudden impact and is more friendly to the cold storage plate 14. The unloading process is the reverse of the process and can also achieve smooth release.

[0051] The outer part of the reversing wheel 622 is provided with an anti-disengagement block fixed on the support frame 232, which can prevent the connecting rope 621 from disengaging from the reversing wheel 622 during the rotation of the support frame 232, thereby ensuring the normal work of the adjusting assembly 6.

[0052] Referring to Figure 7 Further, a recess is formed in the outer wall of the counterweight 61, and a rolling ball is arranged in the recess; the rolling ball abuts against the inner wall of the guide groove 2324, so that the sliding friction between the counterweight 61 and the guide groove 2324 is converted into rolling friction, thereby reducing the friction resistance and enabling the counterweight 61 to slide more smoothly, so that the adaptive adjustment of the position of the abutting plate 41 can be smoothly achieved.

[0053] The implementation principle of the embodiment 2 is that when the cold storage plate 14 is fed into the support frame 232, the abutting plate 41 is automatically in the open position due to the action of the counterweight 61, and the cold storage plate 14 is smoothly fed in. With the overturning of the support frame 232, the action force of the counterweight 61 is weakened, and the abutting plate 41 gently abuts against the cold storage plate 14 under the action of the first elastic member 43, and the automatic clamping is completed. During the horizontal conveying process, the cold storage plate 14 is abutted and fixed. When reaching the unloading position, the support frame 232 is overturned from the vertical state to the horizontal state, the counterweight 61 does not act, and the abutting plate 41 slowly deflects downward during the overturning process of the support frame 232, and the abutting plate 41 always supports the cold storage plate 14, so that sudden deflection or toppling of the cold storage plate 14 during the rotation from the vertical state to the horizontal state can be prevented, and the stable removal of the cold storage plate 14 can be achieved in cooperation with the unloading mechanism 3.

[0054] Embodiment 3 Referring to Figure 9The difference between the embodiment and the embodiment 2 is that, in the embodiment, the connecting component 62 comprises a first connecting rod 623, a second connecting rod 624 and a telescopic rod 625, one end of the first connecting rod 623 is fixedly connected with the abutting plate 41, and the other end of the first connecting rod 623 is hingedly connected with a first end of the telescopic rod 625. A connecting column is fixedly connected with the counterweight 61, the connecting column passes through the support frame 232, and a sliding groove is formed in the support frame 232 for the connecting column to slide; one end of the second connecting rod 624 is fixedly connected with the connecting column, and the other end of the second connecting rod 624 is hingedly connected with a second end of the telescopic rod 625. The telescopic rod 625 can freely extend and retract, and the hinging axes at the two ends of the telescopic rod 625 are arranged in parallel, so that when the clamping frame moves to the side close to the feeding mechanism 1 and is in a horizontal state, the gravity acting on the counterweight 61 can make the second connecting rod 624 move downward, and since the two ends of the telescopic rod 625 are limited to move only in the width direction of the clamping frame, the second connecting rod 624 can move upward through the telescopic rod 625 when the second connecting rod 624 moves downward, so that the abutting plate 41 overcomes the elastic force of the first elastic member 43 and moves upward, so that the abutting plate 41 and the first bearing arm 2322 are arranged in a spaced manner, so that the cold storage plate 14 can smoothly enter between the abutting plate 41 and the first bearing arm 2322.

[0055] Embodiment 4 With reference to Figure 10 The difference between the embodiment and the embodiment 2 is that, in the embodiment, the connecting component 62 comprises a first connecting rod 623, a second connecting rod 624 and a telescopic rod 625, one end of the first connecting rod 623 is fixedly connected with the abutting plate 41, and the other end of the first connecting rod 623 is hingedly connected with a first end of the telescopic rod 625. A connecting column is fixedly connected with the counterweight 61, the connecting column passes through the support frame 232, and a sliding groove is formed in the support frame 232 for the connecting column to slide; one end of the second connecting rod 624 is fixedly connected with the connecting column, and the other end of the second connecting rod 624 is hingedly connected with a second end of the telescopic rod 625. The telescopic rod 625 can freely extend and retract, and the hinging axes at the two ends of the telescopic rod 625 are arranged in parallel, so that when the clamping frame moves to the side close to the feeding mechanism 1 and is in a horizontal state, the gravity acting on the counterweight 61 can make the second connecting rod 624 move downward, and since the two ends of the telescopic rod 625 are limited to move only in the width direction of the clamping frame, the second connecting rod 624 can move upward through the telescopic rod 625 when the second connecting rod 624 moves downward, so that the abutting plate 41 overcomes the elastic force of the first elastic member 43 and moves upward, so that the abutting plate 41 and the first bearing arm 2322 are arranged in a spaced manner, so that the cold storage plate 14 can smoothly enter between the abutting plate 41 and the first bearing arm 2322.

[0056] With reference to Figure 11 and Figure 12, the upper side of the transfer mechanism 2 is further provided with a air supply assembly 8, the air supply assembly 8 is used for supplying air to the inside cavity of the support frame 232 and the abutting plate 41, the air supply assembly 8 comprises a fan (not shown in the figure) and an air supply pipe 81. The upper side of the transfer mechanism 2 is provided with a rack 9, the rack 9 is fixed on the ceiling of the room or the bottom of the rack 9 is supported by a support structure to realize the fixation. The air supply pipe 81 is located above the transfer mechanism 2, the air supply pipe 81 comprises a main pipe 811 and a branch pipe 812, the main pipe 811 is arranged along the length direction of the transfer mechanism 2, the main pipe 811 is provided with two and is arranged in parallel and spaced apart; the branch pipe 812 is arranged along the width direction of the transfer mechanism 2, the branch pipe 812 is provided with a plurality of and is arranged in parallel and spaced apart along the length direction of the main pipe 811; the branch pipe 812 is fixedly connected between the two main pipes 811, and the two ends of the branch pipe 812 are respectively communicated with the two side main pipes 811. The main pipe 811 is communicated with the air outlet side of the fan through a hose, and the bottom end of each branch pipe 812 is connected with a plurality of air outlet pipes 8121, and the bottom end of the air outlet pipe 8121 is provided with an air outlet facing the inside cavity of the support frame 232 and the abutting plate 41. Thus, the air discharged by the fan can enter the air supply pipe 81, and then be discharged downward through the air outlet pipe 8121 and enter the cavity inside the support frame 232 and the abutting plate 41, and finally be discharged outward through the air outlet hole 7, so as to air-cool and cool the cold storage plate 14.

[0057] With reference to Figure 12 , the air supply assembly 8 further comprises a second elastic element 82 and an intermittent connecting component 83; the air supply pipe 81 is slidably connected to the rack 9 along the length direction of the transfer mechanism 2, and a limiting plate 91 is fixedly connected to the rack 9, the limiting plate 91 is used for abutting against the air supply pipe 81 to limit the sliding distance of the air supply pipe 81. The second elastic element 82 is a spring, the second elastic element 82 is horizontally arranged, the second elastic element 82 is located on the side of the air supply pipe 81 away from the limiting plate 91, and the second elastic element 82 is fixedly connected between the air supply pipe 81 and the rack 21. In normal state, the second elastic element 82 is in original length, at this time, the air supply pipe 81 is spaced apart from the limiting plate 91 at one end close to the limiting plate 91, so that the air supply pipe 81 can slide horizontally to the side close to the limiting plate 91. The intermittent connecting component 83 is arranged on the air supply pipe 81, the intermittent connecting component 83 enables the air supply pipe 81 to intermittently abut against the support frame 232, so that the support frame 232 can intermittently push the air supply pipe 81 to slide to the side close to the limiting plate 91.

[0058] With reference to Figure 12 and Figure 13The intermittent connecting component 83 comprises a swing rod 831 and a torsion spring 832. The top end of the swing rod 831 is hinged to the bottom end of the air supply pipe 81, and the axis of the hinge between the swing rod 831 and the air supply pipe 81 is parallel to the width direction of the transferring mechanism 2. The torsion spring 832 is fixedly connected between the swing rod 831 and the air supply pipe 81, and the torsion spring 832 is in a twisted state in normal times, so that the top end of the swing rod 831 abuts against the bottom end of the air supply pipe 81, and at this time, the swing rod 831 is in a vertical state. The end of each support frame 232 is fixedly installed with a push rod 13. When the support frame 232 moves to the top of the chain transmission assembly 22 and the support frame 232 is in a state that the opening faces upward, the top end of the push rod 13 is below the swing rod 831, and the push rod 13 can abut against the swing rod 831.

[0059] With reference to Figure 12 In operation, after the support frame 232 supports the cold storage plate 14, the support frame 232 moves with the chain transmission assembly 22 until the support frame 232 is in a state that the opening faces upward, at this time, the support frame 232 can move horizontally to the right. When the support frame 232 moves, the push rod 13 moves and abuts against one side of the swing rod 831. When the push rod 13 abuts against the swing rod 831, the air outlet at the bottom end of the air outlet pipe 8121 can be aligned with the opening at the top end of the abutting plate 41, so that at this time, more air discharged from the air outlet pipe 8121 can flow into the cavity inside the first bearing arm 2322 and the abutting plate 41, and then be discharged outward through the air outlet hole 7 to blow the part of the cold storage plate 14 that is abutted, so as to achieve better cooling effect. When the support frame 232 moves to the right, the push rod 13 can push the swing rod 831 to move. Because the elastic force of the torsion spring 832 between the swing rod 831 and the air supply pipe 81 is strong, the swing rod 831 moves to the right together with the air supply pipe 81, so that the air supply pipe 81 moves horizontally together with the support frame 232, and thus during the horizontal movement of the support frame 232, air can be continuously supplied to the inside of the support frame 232 and the abutting plate 41, so as to ensure the air supply effect.

[0060] When the air supply pipe 81 moves horizontally to the right for a distance, the right end of the air supply pipe 81 abuts against the limiting plate 91, at which time the limiting plate 91 limits the movement of the air supply pipe 81, and if the support frame 232 continues to move to the right, the support frame 232 will forcibly push the swing lever 831 to swing to the right, and the air supply pipe 81 remains stationary; when the support frame 232 passes the swing lever 831, the swing lever 831 reverses to reset. As the air supply pipe 81 loses the push, the second elastic member 82 will move the air supply pipe 81 to the left to reset to the initial position, so that the air supply pipe 81 can move horizontally to the right together with the support frame 232 again. Thus, in the present application, the air supply pipe 81 can intermittently move horizontally together with the support frame 232, thereby prolonging the time of air supply into the internal cavity of the support frame 232 and the abutment plate 41, so that more air can be discharged through the air exhaust holes 7 to improve the cooling efficiency.

[0061] The implementation principle of embodiment 4 is that when the support frame 232 moves to the vicinity of the air supply assembly 8, the top end of the support frame 232 will move the air supply pipe 81 by pushing the swing lever 831, so that the air supply pipe 81 moves forward together with the support frame 232 for a distance; in this process, the air outlet at the bottom end of the air supply pipe 81 is always aligned with the opening at the top of the support frame 232 and the abutment plate 41, and the high-pressure airflow generated by the fan can continuously flow into the hollow cavity of the support frame 232 and the abutment plate 41, and be sprayed at high speed from the densely arranged air exhaust holes 7, directly acting on the surface of the cold storage plate 14. When the air supply pipe 81 moves to the right to the limit position, the support frame 232 continues to move to pass the swing lever 831, and the air supply pipe 81 loses the push and quickly returns to the initial position under the action of the second elastic member 82, waiting for the next support frame 232. This ingenious linkage of pneumatic and mechanical makes every cold storage plate 14 in the transfer mechanism 2 obtain a continuous and efficient forced air cooling. Thus, the present scheme blows air to cool the area where the cold storage plate 14 contacts with the clamping part, ensuring the uniformity of the cooling of the entire cold storage plate 14, effectively preventing the deformation of the plate, and improving the quality of the final product.

[0062] The above is an optional embodiment of the present application, which does not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
