Description

Technical Field

[0001] This utility model relates to the field of food processing, and is particularly applicable to a whole-plate type side air inlet connecting chain and a chain structure having the same. Background Technology

[0002] With the advancement of science and the development of society, the hygiene and safety of food, the cleanliness of food machinery, and production efficiency are increasingly valued in the food processing field. Currently, in food conveying, especially food cooling and quick-freezing machinery, a mesh belt that can simultaneously achieve high freezing efficiency and easy cleaning is available. Its basic structure is as follows: the mesh belt has chain plates on both sides, and the chain plates are connected together by a connecting rod in the middle. The chain plates are stacked up and down, and transmission is achieved through bottom drive.

[0003] On the one hand, the self-stacking mesh belt with chain links on the side has the disadvantage that the chain links are closed on the side, the mesh surface is not easy to clean and air can only enter from the top, which greatly affects the freezing efficiency. To address the above problems, the current methods employed and their drawbacks are as follows: Solution 1: Use a spiral drive conveyor belt driven by a rotating drum friction. However, the disadvantage is that the bottom of the conveyor belt device needs to be guided and supported by a track. The track is located below the conveyor belt, making the structure complex and difficult to clean. Solution 2: Use a self-stacking mesh belt with bent round steel on the sides. However, the disadvantages are that the manufacturing process of the self-stacking mesh belt with bent round steel is complicated and the production and processing takes a long time. In addition, the positioning requirements of the connection between the round steel and the bottom support of this mesh belt are high, making it difficult to manufacture. Therefore, there is an urgent need for a chain that can achieve side air intake. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] It should be understood that the accompanying drawings are for illustrative purposes only.

[0020] A type of single-plate side air inlet connecting chain, such as Figures 1-5 As shown, the system includes a first connecting plate 110, a second connecting plate 120, and a transition plate 130 for connecting the first connecting plate 110 and the second connecting plate 120. The first connecting plate 110 is offset relative to the second connecting plate 120 in a first direction, and the offset distance ranges from t to 2t, where t is the thickness of the whole-plate side air inlet connecting chain 100. Overall, the first connecting plate 110 and the second connecting plate 120 are located in different planes. In the attached figure, direction A is the first direction.

[0021] Ventilation holes 113 are provided on the first connecting plate 110 and / or the second connecting plate 120. At least one ventilation hole 113 is provided. To ensure effective side air intake, a ventilation hole 113 is provided on both the first connecting plate 110 and the second connecting plate 120. The ventilation hole 113 has a relatively large area, occupying 20%-80% of the area of ​​the first connecting plate 110 or the second connecting plate, resulting in a larger side air intake and improved freezing efficiency. Furthermore, the ventilation hole 113 occupies 40%-60% of the area of ​​the first connecting plate 110 or the second connecting plate. The ventilation hole 113 on the first connecting plate 110 is positioned away from the second connecting plate 120, and the ventilation hole 113 on the second connecting plate 120 is positioned away from the first connecting plate 100.

[0022] To prevent frozen items from falling through the ventilation hole 113, the ventilation hole 113 is positioned high, leaving a blocking portion between the bottom of the ventilation hole 113 and the bottom of the first connecting plate 110 and / or the second connecting plate 120. Furthermore, the ventilation hole 113 is positioned along the centerline of the first connecting plate 110 and / or the second connecting plate 120 and extends towards the top and bottom of the first connecting plate 110 and / or the second connecting plate 120. The blocking portion occupies 1 / 4 of the bottom area of ​​the connecting plate, the ventilation hole 113 occupies 2 / 4 of the middle area of ​​the connecting plate, and the top 1 / 4 of the connecting plate is set as a support portion, which can ensure both large-area ventilation and blocking of items and sufficient support strength.

[0023] The ventilation hole 113 can be circular, square, or irregular in shape. In this solution, the ventilation hole 113 is set as rectangular.

[0024] Because the ventilation hole 113 has a large area and is located close to the turning plate, a first reinforcing rib 123 is provided on the second connecting plate 120 to increase its strength. The first reinforcing rib 123 is arranged along the length of the second connecting plate 120. The first reinforcing rib 123 can be a continuous strip or several discontinuous strips along the length. Furthermore, the upper and lower ends of the first reinforcing rib 123 can also extend toward the side close to the second connecting plate 120 or the first connecting plate 110. The laterally extending first reinforcing rib 123 is located above and / or below the ventilation hole 113. The first reinforcing rib 123 is L-shaped or C-shaped.

[0025] The first reinforcing rib 123 can be formed by extrusion from one side to the other, and the first reinforcing rib 123 is located on one side of the second connecting plate 120 and protrudes towards the other side.

[0026] At least one second reinforcing rib 111 is provided on the first connecting plate 110. The second reinforcing rib 111 extends upward from the bottom of the first connecting plate 110 to the upper edge of the first connecting plate 110 and forms a bearing surface 112 with the top surface of the first connecting plate 110. The thickness of the bearing surface 112 is greater than the thickness of the first connecting plate 110. A portion of the bearing surface 112 at the upper edge is relatively wide, which can not only strengthen the support strength of the first connecting plate 110, but also ensure the stability of the upper whole-plate side air intake connecting chain 100 while providing support. The misalignment between the first connecting plate 110 and the second connecting plate 120 provides misalignment space for the upper and lower stacking of the whole-plate side air intake connecting chain 100, and can further enhance the bending strength of the whole-plate side air intake connecting chain 100.

[0027] The second reinforcing rib 111 is formed by extruding one side of the first connecting plate 110 in a first direction and forming a bulge on the other side of the first connecting plate 110, making the first connecting plate 110 as a whole curved. The height of the bulge is approximately the thickness t of the first connecting plate 110. The second reinforcing rib 111 is set to three and evenly arranged. The length of the second reinforcing rib 111 in the middle is greater than the length of the second reinforcing ribs 111 on both sides. The length of the second reinforcing ribs 111 on both sides is 3 / 4 of the length of the second reinforcing rib 111 in the middle. The bulging direction of the second reinforcing rib 111 is the first direction. During assembly, the first direction is from the direction close to the mesh belt to the direction away from the mesh belt.

[0028] A connection port 150 is provided on one or more of the first connecting plate 110, the second connecting plate 120, and the turning plate 130. At least two connection ports 150 are provided to form a mating structure. The connection port 150 is used to place the connecting rod 200, and the axis of the connecting rod 200 is parallel to the first direction. Further, at least one connection port 150 is provided on the lower part of the first connecting plate 110, and at least one connection port 150 is provided on the lower part of the turning plate 130. In this embodiment, there are two connection ports 150.

[0029] Since the turning plate 130 is at a certain angle, the connecting port 150 located on it is inclined relative to the turning plate 130. Therefore, the contact area between the connecting port 150 and the connecting rod 200 is increased, which can reduce the stress at this point and increase the welding surface, making the mesh belt more firmly fixed.

[0030] An elongated hole 122 is provided on the second connecting plate 120. One end of the elongated hole 122 is close to the first connecting plate 110, and the other end extends away from the first connecting plate 110. The setting direction of the elongated hole 122 is along the direction of the mesh belt movement. Furthermore, the setting direction of the elongated hole 122 is parallel to the upper edge of the second connecting plate 120. When the stacking spiral rises, the movement path of the outer whole plate side air inlet connecting chain 100 is greater than the movement path of the inner whole plate side air inlet connecting chain 100. The connecting rod 200 is inserted into the elongated hole 122 and can slide within the elongated hole 122. This sliding structure is used to compensate for the problem of inconsistent movement paths on both sides.

[0031] The bottom of the first connecting plate 110 is provided with a support foot structure 140. The support foot structure 140 includes a support connecting plate 141 extending from the lower edge of the first connecting plate 110 in a first direction, a limiting connecting plate 142 extending downward from the support connecting plate 141, and a connecting panel connected to the limiting connecting plate 142. A contact connecting plate 145 is provided on the connecting panel. The number of contact connecting plates 145 is the same as the number of connecting ports 150. The contact connecting plates 145 are used to abut against the connecting rod 200 inserted into the connecting port 150.

[0032] The bottom surface of the supporting connecting plate 141 is used to contact the bearing surface 112 of the first connecting plate 110 in the lower whole plate side air inlet connecting chain 100, and plays a supporting role. The limiting connecting plate 142 is used to restrict the upper edge of the first connecting plate 110 from moving away from the mesh belt. Furthermore, the limiting connecting plate 142 is inclined, with the inclination direction towards the first direction and downward. The inclined setting forms a corresponding guiding effect. After the upper edge of the first connecting plate 110 contacts the limiting connecting plate 142, it will enter the supporting connecting plate 141 and contact it due to the inclined guiding effect, ensuring the stable operation of the mesh belt and aligning the mesh belt, so that it can quickly enter the specified position.

[0033] The connecting panel includes a horizontal section 143 and a vertical section 144. The horizontal section 143 is arranged along a first direction, and the vertical section 144 extends upward perpendicular to the first direction. A contact panel 145 is disposed on the vertical section 144. The number of contact panels 145 corresponds to the number of connecting rods 200. The contact panels 145 can abut against the installed connecting rods 200, or the connecting rods 200 can be directly welded to the contact panels 145. In this embodiment, two connecting rods 200 and two contact panels 145 are provided. The contact panels 145 extend from both sides of the vertical section 144 along a second direction, allowing the contact panels 145 to contact or be welded to the cylindrical surfaces of the connecting rods 200. In the attached diagram, direction B represents the second direction.

[0034] A reinforcing groove 146 is provided at the junction of the horizontal section 143 and the vertical section 144, and at the junction of the horizontal section 143 and the limiting panel 142. The reinforcing groove 146 is formed inward by extrusion or stamping, which can improve the strength of the support structure 140.

[0035] A bottom edge plate 160 is formed by extending downward at the lower edge of the second connecting plate 120. The bottom edge plate 160 is inclined in a second direction, that is, the bottom edge plate 160 is inclined downward and towards the mesh belt. A reinforcing groove is also provided on the bottom edge plate 160 to increase the strength of the bottom edge plate 160. The bottom edge plate 160 cooperates with the upper edge of the second connecting plate 120 provided on the lower whole plate side air inlet connecting chain 100 to restrict the movement of the lower whole plate side air inlet connecting chain 100 in the second direction, that is, to restrict the movement towards the mesh belt.

[0036] A chain structure, such as Figure 10 As shown, the device includes a single-plate side air inlet connecting chain 100 and a support chain 300. The single-plate side air inlet connecting chain 100 and the support chain 300 are arranged opposite to each other. At least two connecting rods 200 are fixedly provided between the single-plate side air inlet connecting chain 100 and the support chain 300. Each connecting rod 200 is correspondingly provided with a connecting port 150. The connecting rods 200 are inserted into and fixed in their respective connecting ports 150 to prevent them from falling off during operation. Of course, if the connecting ports 150 are not provided, the connecting rods 200 can be directly fixed to the single-plate side air inlet connecting chain 100 and the support chain 300, including but not limited to welding, bonding, etc.

[0037] A mesh, plastic mesh, or other form of covering with a spacing of 4-16mm can be installed on the connecting rod 200 to prevent items from falling.

[0038] like Figures 6-9 As shown, the support chain 300 is similar in structure to the whole plate type side air inlet connecting chain 100, and also includes a first connecting plate 110, a second connecting plate 120 and a turning plate 130 for connecting the first connecting plate 110 and the second connecting plate 120. The first connecting plate 110 is offset in a first direction relative to the second connecting plate 120.

[0039] Furthermore, the support chain 300 is provided with a support foot structure 140, a connection port 150, and an elongated hole 122, all of which are the same as the structures provided on the whole plate-shaped side air inlet connecting chain 100, and will not be described again.

[0040] Furthermore, heat dissipation holes 1701 can be provided on both the first connecting plate 110 and the second connecting plate 120, and at least one heat dissipation hole 1701 can be provided.

[0041] Furthermore, a second reinforcing rib 111 can be provided on the first connecting plate 110, which is the same structure as that provided on the whole plate side air inlet connecting chain 100, and will not be described again.

[0042] Furthermore, an extruded part 121 can be formed on the first connecting plate 110 and / or the second connecting plate 120 in a second direction. The extruded part 121 can enhance the bending strength of the second connecting plate 120. The area covered by the extruded part 121 is at least 20%-50% of the second connecting plate 120, and the protruding distance does not exceed the thickness t of the second connecting plate 120.

[0043] Furthermore, ventilation openings 113 may be provided on the first connecting plate 110 and / or the second connecting plate 120.

[0044] This utility model mainly designs a whole-plate side-inlet connecting chain and a chain structure with it. The open side of the chain greatly improves the freezing efficiency. The use of a whole-plate connecting chain simplifies the processing technology, shortens the production time, improves the matching accuracy of the chain, reduces the complexity of the chain manufacturing process, and ensures that the chain can be stably and reliably stacked in a spiral. The second reinforcing rib 111 can increase the strength of the first connecting plate 110, and the first reinforcing rib 123 can increase the strength of the second connecting plate 120. The connection port 150 is provided to facilitate the fixing of the connecting rod 200.
