Description

Technical Field

[0001] The invention relates to the technical field of sealing devices, and in particular to a sealing device and process for producing rust-proof bags. Background Art

[0002] Anti-rust bags have good plasticity, can overcome the weakness of insufficient protection of traditional anti-rust products, and have good transparency. With the development of society, anti-rust bags are put into use in large quantities, and anti-rust bags are often used in conjunction with sealing devices during the production process.

[0003] In the prior art, sealing machines are often used to process bags and other products, such as CN215943846U. The telescopic end of the clamping cylinder drives the placement plate to move downward, thereby driving the rotating shaft to move downward on the rotating disk, and the positions of the two suction cups are moved to the anti-rust bag. The two suction cups adsorb the anti-rust bag. The clamping motor drives the drive shaft to rotate, thereby driving the rotating disk to rotate on the fixed frame through the belt. The rotation of the rotating disk drives the position of the transfer plate to rotate, and the anti-rust bag adsorbed on the suction cup is rotated to the unloading device, and the anti-rust bag is placed on the unloading device, thereby realizing the transfer of the anti-rust bag and facilitating the recovery of the processed anti-rust bag.

[0004] However, the above technical solution performs the sealing operation directly on the conveyor belt. When the material is in the conveying state, the components that cannot be sealed are in a relatively static state, which causes the material to be easily damaged due to a brief stagnation during the sealing operation, affecting the production of the equipment, increasing the defective rate of the equipment, and increasing the economic losses of the users. Improvements are needed in this regard.

[0017] The following steps are involved:

[0018] S1: Before processing, pull the ferrule downward, and the ferrule will then be separated from the limit rod, the compression spring will be deformed under force to generate elastic force, and then the blocking hook will be rotated. When the blocking hook moves to a horizontal state, the used material roll will be taken off, and then a new material roll will be placed on the support rod, and then the blocking hook will be rotated so that the blocking hook is sleeved on the shaft of the material roll, and then the ferrule will be released, and the compression spring will pull the ferrule upward, and the ferrule will be sleeved on the limit rod immediately, limiting the rotation of the blocking hook, and then the material will be pulled and passed through the first set of conveying rollers, between the carrier plate and the control block, and the second set of conveying rollers in sequence, and then the production operation can begin;

[0019] S2: During processing, the material remains in a conveying state, the control cylinder contracts, and the cylinder then drives the control block to press down through the transmission rod.

The carrier plate squeezes the reset spring during the displacement process, and the reset spring is deformed by force to generate elastic force. After the sealing operation is completed, the cylinder immediately pushes the control block upward through the transmission rod, and the control block immediately drives the heating plate to separate from the material. Then the reset spring pushes the carrier plate to reset, and the servo motor is controlled to reverse, and the servo motor drives the slider and the control block to reset, which is convenient for the next sealing operation.

[0020] S3: When the cylinder drives the control block to press down through the transmission rod, the control block drives the positioning block and the insert block to move.

Then the insert block is inserted into the slot. While carrying out the sealing operation, the control block can drive the carrier plate to move, so as to achieve relative stillness of the control block, the carrier plate and the material sealing point. When the carrier plate is displaced significantly, the resisting block touches the stabilizing slot, and then the resisting block squeezes the stabilizing spring. After the carrier plate is reset, the stabilizing spring pushes the resisting block to reset.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention sets a sealing mechanism. During processing, the material keeps in a conveying state, controls the cylinder to contract, and then drives the control block to press down through the transmission rod. Then the material is clamped by the heating plate and the pad, the heating plate generates heat and completes the sealing operation. During the sealing operation, the servo motor runs and drives the threaded rod to rotate, and the threaded rod then drives the slider, the control block and the carrier plate to move in a direction close to the servo motor, ensuring that the material is in a relatively static state with the heating plate and the pad during the sealing operation. The carrier plate squeezes the reset spring during the displacement process, and the reset spring is deformed by force to generate elastic force, completing the sealing operation. After the sealing operation is completed, the cylinder immediately pushes the control block upward through the transmission rod, and the control block immediately drives the heating plate to separate from the material. Then the reset spring pushes the carrier plate to reset, controls the servo motor to reverse, and the servo motor drives the slider and the control block to reset, so as to facilitate the next sealing operation. By setting up the sealing mechanism, it is convenient to seal the material, ensure that the material is in a relatively static state with the sealing components during the conveying state, and reduce the material damage due to short stagnation during the sealing operation, thereby ensuring stable production of the equipment, reducing the defective rate of the equipment, and reducing the economic loss of users.

[0023] 2. The present invention sets a stabilizing mechanism. When the cylinder drives the control block to perform a downward pressing operation through the transmission rod, the control block drives the positioning block and the inserting block to move. The positioning block is then inserted into the positioning groove on the assembly block. The positioning block can cooperate with the assembly block due to its arc-shaped structure to complete the positioning operation of the control block and the carrier plate. Then the inserting block is inserted into the slot. While the sealing operation is carried out, the control block can drive the carrier plate to move to achieve relative stillness of the control block and the carrier plate and the sealing part of the material. When the carrier plate is displaced significantly, the resisting block touches the stabilizing groove, and then the resisting block squeezes the stabilizing spring. After the carrier plate is reset, the stabilizing spring pushes the resisting block to reset. By setting the stabilizing mechanism, it is convenient for the auxiliary equipment to complete the positioning operation, improve the processing accuracy of the equipment, ensure the normal production of the equipment, and increase the service life of the equipment.

[0024] 3. The present invention sets a protective mechanism. Before processing, the sleeve is pulled downward, and the sleeve is then separated from the limit rod. The compression spring is deformed by force to generate elastic force, and then the blocking hook is rotated. When the blocking hook moves to a horizontal state, the used material roll is taken off, and then a new material roll is placed on the support rod. Then the blocking hook is rotated so that the blocking hook is sleeved on the axis of the material roll. Then the sleeve is released, and the compression spring pulls the sleeve upward. The sleeve is immediately sleeved on the limit rod to limit the rotation of the blocking hook. Then the material is pulled and passed through the first group of conveying rollers, the space between the carrier plate and the control block, and the second group of conveying rollers in sequence, and then the production operation can be started. By setting the protective mechanism, the positioning operation of the material roll is facilitated, the difficulty of replacing the material roll is reduced, the usability of the equipment is improved, and the normal use of the equipment is convenient.

3. The sealing process for producing the sealing device for anti-rust bags according to any one of claims 1 to 2 comprises the following steps: S1: Before processing, the clamping sleeve (75) is pulled downward, and the clamping sleeve (75) is then separated from the limiting rod (74), and the compression spring (76) is deformed by force to generate elastic force, and then the blocking hook (72) is rotated. When the blocking hook (72) moves to a horizontal state, the used material roll is taken off, and then a new material roll is placed on the support rod (71), and then the blocking hook (72) is rotated so that the blocking hook (72) is sleeved on the shaft of the material roll, and then the clamping sleeve (75) is released, and the compression spring (76) pulls the clamping sleeve (75) upward, and the clamping sleeve (75) is then sleeved on the limiting rod (74), limiting the rotation of the blocking hook (72), and then the material is pulled and passed through the first group of conveying rollers (3), between the carrier plate (511) and the control block (504), and the second group of conveying rollers (3) in sequence, and then the production operation can be started; S2: During processing, the material is kept in the conveying state, the control cylinder (505) is controlled to contract, and the cylinder (505) then drives the control block (504) to press down through the transmission rod (517), and then the material is clamped by the heating plate (516) and the pad (512), the heating plate (516) is heated and the sealing operation is completed. During the sealing operation, the servo motor (507) runs and drives the threaded rod (506) to rotate, and the threaded rod (506) then drives the slider (502), the control block (504) and the carrier plate (511) to move in the direction close to the servo motor (507), ensuring that the material is in contact with the heating plate (516) and the pad (512) during the sealing operation. The plate (516) and the pad (512) are in a relatively static state. The carrier plate (511) squeezes the reset spring (509) during the displacement process. The reset spring (509) is deformed by force to generate elastic force. After the sealing operation is completed, the cylinder (505) immediately pushes the control block (504) upward through the transmission rod (517). The control block (504) then drives the heating plate (516) to separate from the material. Then the reset spring (509) pushes the carrier plate (511) to reset, and the servo motor (507) is controlled to reverse. The servo motor (507) drives the slider (502) and the control block (504) to reset, so as to facilitate the next sealing operation. S3: The cylinder (505) then drives the control block (504) to perform a downward pressing operation through the transmission rod (517), and the control block (504) drives the positioning block (68) and the insert block (69) to move, and the positioning block (68) is then inserted into the positioning groove (64) on the assembly block (63). The positioning block (68) can cooperate with the assembly block (63) due to its arc-shaped structure to complete the positioning operation of the control block (504) and the carrier plate (511), and then the insert block (69) is inserted. In the slot (65), while the sealing operation is being carried out, the control block (504) can drive the carrier plate (511) to move, so as to achieve relative stillness of the control block (504), the carrier plate (511) and the material sealing portion. When the carrier plate (511) is displaced significantly, the stop block (61) touches the stabilizing groove (513), and then the stop block (61) squeezes the stabilizing spring (66). After the carrier plate (511) is reset, the stabilizing spring (66) pushes the stop block (61) to reset.
