DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Example 1: Figure 1-9 As shown, a finely adjustable stacking freezing mesh belt production device includes a material storage box 1, a first belt conveyor 2 and a control panel, wherein a sleeve mechanism is provided on the side of the first belt conveyor 2;

[0032] The sleeve-threading mechanism includes a carrying assembly and an opening and closing assembly, the carrying assembly includes a second belt conveyor 3 and a plurality of push rods, the second belt conveyor 3 is connected to an external fixed structure through a bracket, and the plurality of push rods are evenly arranged on the upper end of the belt of the second belt conveyor 3 and are matched with the first belt conveyor 2;

[0033] The opening and closing assembly includes a connecting rod 4, an air supply and a controller. The air supply is connected to an external fixed structure through a bracket and is located on the other side of the second belt conveyor 3. The number of the connecting rods 4 and the controller matches the number of the push rod devices and corresponds one to one. The connecting rod 4 is arranged between the corresponding push rod device and the air supply and is hollow. The controller is arranged in the connecting rod 4 and is connected to the air path of the air supply. The air supply is connected to an external air supply mechanism.

[0034] When the refrigeration mesh belt is assembled and produced, a cross bar 91 for inserting the spiral elastic belt net 9 is stored in the material storage box 1. The spiral elastic belt net 9 of the refrigeration mesh belt is placed on the belt of the first belt conveyor 2 by manual or external feeding mechanical claws, and then the first belt conveyor 2 (only the belt part is shown in the drawings of the present embodiment) is used to uniformly convey it to move toward the insertion mechanism side, wherein the spiral elastic belt net 9 is alternately placed in forward and reverse rotation, and the running speed of the second belt conveyor 3 in the insertion mechanism matches the running speed of the first belt conveyor 2, so that the intersection position of two adjacent spiral elastic belt nets 9 can correspond to the push rod device, and then when the push rod device moves with the second belt conveyor 3, the cross bar 91 is inserted into the two adjacent spiral elastic belt nets 9 to generate a connection;

[0035] Among them, when the push rod moves with the movement of the second belt conveyor 3, the position of the connecting rod 4 moves synchronously, and the controller produces a relative displacement at the position of the air supply device until the controller starts to use pneumatic drive to drive the push rod, thereby making the cross bar 91 perform the sleeve insertion action. After the sleeve insertion is completed, the controller is used to switch the air path to achieve reset, thereby achieving a circulation effect. In this way, during assembly production, the time for alignment and sleeve insertion can be effectively reduced, thereby improving production efficiency and production continuity, and there is no need to intermittently open and close to adapt to the alignment needs of assembly between components.

[0036] The push rod device includes a rod carrying bucket 5, a push piece 51 and a slide bar 52. A receiving groove 53 is opened on the upper side of the rod carrying bucket 5, and a movable groove 54 connected to the receiving groove 53 is opened on the lower side of the rod carrying bucket 5. The opening size between the receiving groove 53 and the movable groove 54 is smaller than the diameter size of the cross bar 91 of the mesh belt. The push piece 51 is slidably arranged in the receiving groove 53 and extends into the movable groove 54. The slide bar 52 is slidably arranged in the movable groove 54 and one end is connected to the push piece 51. One end of the connecting rod 4 is connected to the rod carrying bucket 5, and the other end of the slide bar 52 slides and seals to extend out of the movable groove 54 and then extends into the connecting rod 4. The connecting rod 4 has a piston 55 connected to the connecting rod 4 in a sliding seal.

[0037] The air supply device includes a fixed ring seat 6 and a movable ring belt 61. The fixed ring seat 6 has an overall runway-shaped structure and a U-shaped recessed structure in the middle. The movable ring belt 61 is slidingly sealed in the U-shaped recessed opening of the fixed ring seat 6 and cooperates with it to form a closed space. The other end of the connecting rod 4 is connected to the movable ring belt 61, and the closed space is connected to the external air supply mechanism.

[0038] In the initial state, air is input into the connecting rod 4 through the controller and pushes the piston 55 to move toward the side close to the second belt conveyor 3, and then the piston 55 pushes the slide bar 52 to make the push piece 51 away from the first belt conveyor 2. After the rod-carrying bucket 5 is transported along the second belt conveyor 3 to the corresponding storage box 1, a cross bar 91 will be put into the receiving groove 53 in the storage box 1. The putting can be done by setting an annular belt on a plurality of rod-carrying buckets 5, and a notch matching the receiving groove 53 is provided on the annular belt. In this way, the material is unloaded when the notch corresponds to the storage box 1. It can also be done by using a position sensor to cooperate with the opening and closing The valve method is not limited to specific material feeding in this embodiment. When the cross bar 91 is placed into the receiving groove 53, it will be continuously transported by the second belt conveyor 3 and correspond to the spiral elastic belt net 9 also transported by the first belt conveyor 2. At this time, the controller switches the air circuit, so that the piston 55 in the connecting rod 4 moves toward the side of the air supply device, that is, the push plate 51 is pulled by the sliding rod 52, so that the push plate 51 pushes the cross bar 91 to insert into the spiral elastic belt net 9 to complete the connection, and the movable ring belt 61 in the air supply device will move synchronously in the opening of the fixed ring seat 6 under the drive of the connecting rod 4, without affecting the movement of the components.

[0039] Example 2: Figure 3 , 6 As shown, the structure in Example 1 is embodied, and the controller includes a movable pin 7, a top plate 71 and a spring 72. The movable pin 7 slides and seals through the connecting rod 4 and the movable ring belt 61 and extends into the closed space formed by the fixed ring seat 6 and the movable ring belt 61. The top plate 71 is concentrically connected to the movable pin 7 and is located in the closed space. The spring 72 is sleeved on the movable pin 7 and is located between the top plate 71 and the movable ring belt 61.

[0040] The movable pin 7 is provided with a U-shaped air passage 73, and the openings on both sides of the U-shaped air passage are respectively located in the closed space and the hollow structure of the connecting rod 4. A bypass channel 74 connected to the U-shaped air passage 73 is also provided in the middle of the movable pin 7. A closing sleeve 75 matching the movable pin 7 is provided in the connecting rod 4. Air ports 76 are provided on the upper side of the connecting rod 4 near the movable ring belt 61 and the load-bearing bucket end. The two air ports 76 are connected through an air pipe. Pressure valves are provided on the left and right sides of the connecting rod 4. The inner wall of the fixed ring seat 6 is provided with a trapezoidal guide platform 77 matching the movable pin 7, and the length of the trapezoidal guide platform 77 matches the length of the upper end of the second belt conveyor 3.

[0041] In the initial state, the movable pin 7 is affected by the top plate 71 and the spring 72 and will keep moving toward the side of the fixed ring seat 6. At this time, the bypass channel 74 of the movable pin 7 is closed in the connecting rod 4, that is, the air path is only connected to the openings on both sides of the U-shaped air channel 73, that is, the space near the fixed ring seat 6 in the connecting rod 4 is connected to the closed space relative to the piston 55, so that the input air pushes the piston 55 to move toward the side of the second belt conveyor 3.

[0042] When the movable pin 7 continues to move with the connecting rod 4 until the end of the movable pin 7 abuts against the trapezoidal guide platform 77, the movable pin 7 will slide toward the inner side of the connecting rod 4 until the U-shaped air channel 73 is located at one side of the connecting rod 4 and extends into the closed sleeve 75, and the bypass channel 74 corresponds to the air port 76 of the connecting rod 4. At this time, the air in the closed space is input into the connecting rod 4 through the U-shaped air channel 73, the air port 76, and the air pipe into the side of the second belt conveyor 3 relative to the piston 55, that is, the piston 55 is pushed to move away from the second belt conveyor 3, so as to achieve a reciprocating pushing effect. The length of the trapezoidal guide platform 77 corresponds to the matching insertion area, thereby achieving the effects of automatic insertion, automatic resetting and high matching. Further, in order to ensure the smoothness of component movement, the setting of the pressure valve can discharge the air in the connecting rod 4, but will not affect the air's push on the piston 55, thereby avoiding malfunctions caused by the inability to compress and discharge the air. Furthermore, the number of top sheets 71 can also be two, and the other top sheet 71 is arranged on the side of the live pin 7 located in the connecting rod 4 and on the rear side of the U-shaped air duct 73, which is used to prevent the live pin 7 from falling off or the opening of the U-shaped air duct 73 from being closed.

[0043] Example 3: Figure 1 As shown, based on a further development of Example 1, the belt surface of the first belt conveyor 2 is provided with a positioning groove 21 that matches the mesh belt.

[0044] A tightening device is also provided at the upper end of the first belt conveyor 2, and the tightening device includes a third belt conveyor 8 and a tightening belt 81. The third belt conveyor 8 is connected to an external fixed structure. The tightening belt 81 is provided on the belt surface of the third belt conveyor 8 and matches the belt of the first belt conveyor 2. The belt side of the first belt conveyor 2 is also provided with a docking ring matching a plurality of receiving buckets. The spacing positions of the docking rings and the belt conveying speed of the first belt conveyor 2 match the spacing positions of the receiving buckets and the belt conveying speed of the second belt conveyor 3.

[0045] The opening of the positioning groove 21 can match the edge line of the spiral elastic belt net 9, so that the spiral elastic belt net 9 is more stable when placed on the belt of the first belt conveyor 2, reducing plane displacement, and performing preliminary positioning to facilitate subsequent threading. The third belt conveyor 8 in the compressor is synchronized with the conveying speed of the first belt conveyor 2, and the running direction is opposite to that of the first belt conveyor 2 in an external meshing state. In this way, the tightening belt 81 can be used to press and limit the spiral elastic belt net 9 at the upper end of the first belt conveyor 2, thereby further improving the accuracy of threading.
