Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, and specifically relates to a cooling and conveying system. Background Art

[0002] The preparation process of old soup chicken needs to go through steps such as soup boiling, chicken cooking, pickling, and packaging. The inventor is committed to the production field of old soup chicken. During the packaging process, the pickled old soup chicken is sorted and then put into vacuum packaging, and after high-temperature sterilization, it is externally packaged. After high-temperature sterilization, the vacuum-packed old soup chicken needs to be cooled and then packed into gift boxes. The cooling usually includes two steps. First, the surface is cooled by cooling water, and then the packaged old soup chicken is conveyed to a fan for cooling and drying. However, the existing conveyor usually adopts a mesh belt conveyor, and the chain at the edge position is exposed on the upper end surface. The inventor found that the vacuum packaging bag is often scratched, and even squeezed into the chain to damage the packaging bag, reducing the yield of vacuum-packed old soup chicken. Moreover, the fan installed on the existing conveyor has a small coverage area, reducing the range of air-drying and cooling, and there is a possibility that the vacuum packaging at the edge position cannot be dried and cooled. Content of the Utility Model

[0003] To solve the technical problems existing in the above background art, the utility model provides a cooling and conveying system.

[0004] The technical solution of the utility model is as follows:

[0005] A cooling and conveying system includes two parallel installation frames, and a conveyor mesh belt is installed between the installation frames through a chain transmission device.

[0006] The height of the installation frame is higher than the upper end surface of the conveyor mesh belt. Along the length direction, multiple groups of mounting plates are oppositely installed at the upper ends of the two installation frames, and a support plate is installed between the mounting plates in the same group. Two fans are installed on the support plate, and air collecting hoods are installed at the air outlets of the two fans.

[0007] The adjacent ends of the two air collecting hoods are in contact with each other, and the sum of their widths is not less than the width of the conveyor mesh belt.

[0008] A protection component is installed at the two installation frames, which can block the transmission chain of the chain transmission device.

[0009] The connection method between the support plate and the mounting plate is that the mounting plate is provided with a mounting groove from the upper end surface downward, and both ends of the support plate are provided with mounting bolts, and the mounting bolts pass through the mounting groove outward and are fixed by nuts.

[0010] To improve the installation stability of the support plate, two mounting grooves are provided, and they are symmetrically arranged with respect to the vertical center line of the mounting plate.

[0011] To facilitate the passage of vacuum-packed old soup chickens and ensure a certain drying and cooling effect, the distance between the bottom end of the air collecting hood and the conveyor mesh belt is 15 cm - 25 cm.

[0012] The specific design of the protection component is that the protection component is a PVC flexible film, with one end fixed to the upper end of the mounting frame and the other end extending obliquely towards the conveyor mesh belt, and the extending end exceeding the transmission chain.

[0013] The protection component can also be designed as follows: the protection component includes an L-shaped airbag adhered to the inner side of the mounting frame, and its horizontal end extends towards the conveyor mesh belt and exceeds the transmission chain;

[0014] An air inlet is provided at the upper end of the L-shaped airbag, and the lowest position at the bottom end of the air inlet is higher than the conveyor mesh belt. The setting of the L-shaped airbag can prevent the packaging bag from wearing against the chain. Compared with the PVC flexible film, since the packaging bag moves forward on the conveyor, it is easy to move onto the PVC flexible film, resulting in friction during movement. By setting the airbag, when the packaging bag moves onto the airbag, the elasticity of the airbag can bounce it back onto the conveyor mesh belt, enabling it to be normally conveyed on the conveyor mesh belt, and its durability is stronger than that of the PVC flexible film.

[0015] To improve the stability of the airbag, multiple connecting ropes are connected between the vertical section and the horizontal section of the L-shaped airbag.

[0016] To improve the wear resistance of the L-shaped airbag, wear-resistant pads are adhered to the bottom end of the L-shaped airbag and the three end faces close to the air collecting hood.

[0017] To enable the L-shaped airbag to play a protective role and not be too long to compress the width of the conveyor mesh belt, the length by which the horizontal end of the L-shaped airbag extends beyond the transmission chain is 4 cm - 6 cm.

[0018] To support the entire conveyor system, support columns are installed at the bottom of both mounting frames.

[0019] The beneficial effects of the present utility model are as follows: The present utility model is a cooling and conveying system. Firstly, by setting a conveyor mesh belt driven by a transmission device, it can realize the conveyance of vacuum-packed old soup chickens, and in cooperation with multiple sets of installed fans, it realizes the cooling and drying of old soup chickens during transportation; secondly, two fans are set in each row, and the air collecting hood at the bottom of the fan can cover the width of the conveyor mesh belt, so that the old soup chickens at the edge during transportation can also be affected by the air flow, avoiding the generation of cooling and drying dead angles and ensuring the drying effect; finally, by setting a protection component, it can block the transmission chain of the conveyor system, prevent the vacuum packaging bag from moving to the chain, avoid damage to the packaging bag, and improve the yield rate of vacuum-packed old soup chickens.

[0030] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings.

[0031] First Embodiment

[0032] As mentioned in the background art, after vacuum packaging the old soup chicken, high-temperature sterilization is required, and then cooling and drying are carried out. The cooling and drying are usually carried out during the conveying process. First, it is conveyed through the cooling pool, and then moved to the cooling and drying area to complete the cooling and drying on the conveyor belt. However, the existing cooling and drying equipment has many defects. On the one hand, the coverage of the cooling and drying is not complete. On the other hand, the chain at the edge of the conveyor belt is likely to damage the vacuum packaging, both of which result in a reduction in the finished product rate. Therefore, the inventor made improvements on the existing basis and designed a new cooling and conveying system, which will be specifically described below with reference to the drawings.

[0033] This embodiment provides a cooling and conveying system. Refer to Figure 1, including two parallel installation frames 1, and a conveyor mesh belt 2 is installed between the installation frames 1 through a chain drive device. The conveyor mesh belt 2 is in the form of a metal mesh, and the chain drive device includes a drive motor arranged outside the installation frame 1, which drives the conveyor mesh belt to rotate in the form of a sprocket and a drive chain 8. The existing technology can be used here. This solution does not improve the conveyor mesh belt 2 and the drive device, so there is no need for redundant description. Moreover, in order to support the entire cooling conveyor system, support columns 11 are installed at the bottoms of the two installation frames 1 to support on the ground.

[0034] In this embodiment, the height of the installation frame 1 is higher than the upper end face of the conveyor mesh belt 2, and the height difference is between 40 cm and 50 cm, ensuring the safety of the vacuum-packed old soup chicken during transportation on the conveyor mesh belt 2. A plurality of groups of mounting plates 3 are oppositely installed along the length direction at the upper ends of the two installation frames 1. Each group has two, combined Figure 5 , respectively on the two mounting plates 3, the two are oppositely installed, and a support plate 4 is installed between the same group of mounting plates 3. The support plate 4 spans above the conveyor mesh belt 2. Specifically, the mounting plate 3 is provided with a mounting groove 9 opening downward from the upper end face. Each mounting plate 3 is provided with two mounting grooves 9, and they are symmetrically opened with respect to the vertical center line of the mounting plate 3, which can ensure the balance and stability of the installation of the support plate 4. And both ends of the support plate 4 are provided with mounting bolts 10, and the mounting bolts 10 pass outward through the mounting grooves 9 and are fixed by nuts. Two blowers 5 are installed on the support plate 4, and the air outlets of the blowers 5 are arranged facing the conveyor mesh belt 2. And air collecting covers 6 are installed at the air outlets of both blowers 5. A number of vacuum-packed old soup chickens advance on the conveyor mesh belt 2 and pass through multiple blowers 5 in sequence for cooling and drying.

[0035] It should be noted that the two adjacent ends of the two air collecting covers 6 are in contact with each other, and the sum of their widths is not less than the width of the conveyor mesh belt 2, that is, the two air collecting covers 6 can at least cover the entire width of the conveyor mesh belt 2, ensuring that the air flow of the blower 5 can directly blow on the edge position of the conveyor mesh belt 2 and ensuring the cooling and drying effect. The distance between the bottom end of the air collecting cover 6 and the conveyor mesh belt 2 is 15 cm - 25 cm, which can not only ensure the smooth passage of the vacuum packaging bag but also ensure that the air collecting cover 6 is not too far from the packaging bag, maintaining a proper distance and ensuring the cooling and drying effect of the old soup chicken.

[0036] As the main design point of this solution, combined Figure 1, at two mounting brackets 1, a protective component 7 is installed, which can shield the drive chain 8 of the chain drive device and prevent friction damage from occurring with the drive chain 8 during the transportation of vacuum packaging bags. Among them, this embodiment is one of the implementation methods adopted by the inventor, and the implementation method of this method is relatively simple. Specifically, the protective component 7 is a PVC flexible film 71, whose length is the same as that of the mounting bracket 1, and one end is fixed to the upper end of the mounting bracket 1, which can be fixed by bonding or bolts, etc. The other end extends obliquely towards the conveyor belt 2, and the PVC flexible film 71 can be extended downward to the shape shown in Figure 1 by utilizing the thermoplasticity of the PVC flexible film 71. The extended end exceeds the drive chain 8 to ensure that the drive chain 8 can be shielded, and the lowest position will not touch the conveyor belt 2.

[0037] Embodiment 2

[0038] Using the PVC flexible film 71 can achieve the protective effect, but the old soup chicken in vacuum packaging is prone to staying on the PVC flexible film 71 and pressing it down to cause wear with the conveyor belt 2, which has certain defects. Therefore, the inventor designed a new protective component 7. Specifically, in combination with Figure 3 and Figure 4 , the protective component 7 includes an L-shaped airbag 72 adhesively bonded to the inner side of the mounting bracket 1. Its horizontal end extends towards the conveyor belt 2 and exceeds the drive chain 8. An inflation port 73 is provided at the upper end of the L-shaped airbag 72, and the lowest position of the bottom end of the inflation port 73 is higher than the conveyor belt 2. Through the elasticity of the L-shaped airbag 72, it can be ensured that when the old soup chicken in vacuum packaging moves to the edge of the airbag, it can be bounced back to the conveyor belt 2 through the reaction force. Moreover, the length by which the horizontal end of the L-shaped airbag 72 extends beyond the drive chain 8 is 4 cm - 6 cm, so that while the protective end plays a protective role, it will not overly compress the width of the conveyor belt 2.

[0039] Furthermore, in combination with Figure 6 , a plurality of connecting ropes 74 are connected between the vertical section and the horizontal section of the L-shaped airbag 72. Through the arrangement of the connecting ropes 74, when the inflation port 73 is inflated, the L-shaped airbag 72 expands and forms. The connecting ropes 74 can provide a certain pulling force to the horizontal section to ensure its stability. Moreover, in order to prevent the old soup chicken packaging bag from wearing the L-shaped airbag 72, wear-resistant pads 75 are adhesively bonded to three end faces of the L-shaped airbag 72 close to the air collecting hood 6. Both the L-shaped airbag 72 and the wear-resistant pads 75 can be made of transparent materials for convenient observation. Further, wear-resistant pads 75 are also provided at the bottom end of the L-shaped airbag 72, which can ensure that when the gravity of the old soup chicken packaging bag acts on the airbag, the L-shaped airbag 72 deforms downward onto the conveyor belt 2, and contact occurs between the two to reduce wear.
