Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of chemical metal surface treatment, and relates to a lead strip feeding machine adjusting mechanism. BACKGROUND

[0002] In the field of lead strip processing and production, the lead strip feeding machine is one of the key equipment to ensure the smooth progress of the production process. The main function of the lead strip feeding machine is to accurately and stably deliver the lead strip to the subsequent processing procedure, and its performance directly affects the efficiency of the entire production process and the product quality.

[0003] In actual production, the lead strip feeding machine often faces many problems. First, it is not easy to ensure that the upper and lower feeding rollers reliably press the lead strip, and if the pressing force is insufficient, the lead strip may slip or deviate during the delivery process, affecting the feeding accuracy; if the pressing force is too large, the lead strip may be deformed, or even the equipment may be damaged.

[0004] Secondly, adjusting the gap between the upper and lower feeding rollers under the pressing state is also a difficult problem. If the gap is too large, the lead strip delivery will be unstable; if the gap is too small, it may increase the friction force, causing the lead strip to wear or increasing the energy consumption of the equipment.

[0005] In addition, in the continuous feeding process, cumulative errors are difficult to avoid, and if they cannot be eliminated in time, they will seriously affect the product quality.

[0006] In view of the above problems, the following solutions are currently available:

[0007] For the problem of ensuring the pressing force, some manufacturers use complex hydraulic or pneumatic pressing devices, but such devices are high in cost, complex in maintenance, and slow in response speed.

[0008] In terms of adjusting the gap between the feeding rollers, some enterprises use manual adjustment, but the accuracy is difficult to guarantee, and each adjustment requires shutdown, affecting the production efficiency.

[0009] As for eliminating cumulative errors, some use additional sensors and complex control systems, but this will increase the cost of the equipment and the complexity of the system.

[0010] Considering the advantages and disadvantages of these solutions in the production process, the lead strip feeding machine adjusting mechanism of the present application realizes reliable pressing of the upper and lower feeding rollers through a simple mechanical structure, accurately adjusts the gap between the feeding rollers by using a gap adjusting bolt, and sets a relaxation cam to eliminate the cumulative errors in continuous feeding. This design not only has a lower cost and is easy to maintain, but also effectively solves the problems in actual production, improves the feeding accuracy and production efficiency. SUMMARY

[0011] The application provides a lead belt feeder adjusting mechanism to solve the problems of difficult control of pressing force, inconvenient adjustment of feeder roller gap, and difficult elimination of continuous feeding cumulative error in the existing lead belt feeding process, and realizes high precision, high efficiency and stability of lead belt feeding.

[0012] To solve the above problems, the technical scheme adopted by the application is:

[0013] A lead belt feeder adjusting mechanism, characterized in that it comprises a base, a buffer mechanism is arranged on the base, a driving device is arranged in the buffer mechanism, an output shaft of the driving device is fixedly connected with a loosening cam, a sliding piece is arranged on one side of the loosening cam, the sliding piece is slidingly connected with the buffer mechanism to form a structure that can slide up and down, a roller that is meshingly connected with the loosening cam is mounted on the sliding piece, a fixing piece is arranged at the lower end of the sliding piece, the fixing piece is connected with the buffer mechanism through an adjusting screw, and is used for adjusting the position of the fixing piece, a lower pressing plate is connected with the lower end of the fixing piece in a matched mode, the lower pressing plate is used for controlling the pressing force on the lead belt, a conveying device is arranged on one side of the buffer mechanism, a plurality of upper feeding rollers and lower feeding rollers are arranged side by side on the conveying device, and a gap between the upper feeding rollers and the lower feeding rollers is used for the lead belt to pass through, and an adjusting piece is arranged at the position above the upper feeding rollers, the adjusting piece is a threaded adjusting piece, and the upper feeding rollers are adjusted to move up and down through the rotation of the adjusting piece.

[0014] The principle of the scheme is that:

[0015] The driving device drives the loosening cam to rotate, the roller that is meshingly connected with the loosening cam moves accordingly, thereby pushing the sliding piece to slide up and down in the buffer mechanism, the fixing piece at the lower end of the sliding piece is connected with the buffer mechanism through the adjusting screw, the position of the fixing piece can be adjusted, thereby controlling the pressing force of the lower pressing plate on the lead belt, the plurality of upper feeding rollers and lower feeding rollers on the conveying device are used for conveying the lead belt, and the lead belt passes through the gap between them. The upper feeding rollers can be moved up and down through the rotation of the threaded adjusting piece, thereby adjusting the gap between the upper feeding rollers and the lower feeding rollers to adapt to lead belts of different thicknesses, and ensuring the stability and precision of lead belt conveying. The buffer mechanism plays a buffering role, when the speed or tension changes during lead belt conveying, the impact force on lead belt conveying is reduced through the cooperative work of the loosening cam, the sliding piece and other components, at the same time, the cumulative error caused by continuous feeding is eliminated, and the stability and accuracy of lead belt feeding are ensured.

[0016] The beneficial effects of the scheme are that:

[0017] By relaxing the cooperation of the cam and the slide, the roller can effectively buffer the impact force of the lead belt during the conveying process, reduce the influence of speed or tension changes on the stability of the lead belt conveying, and reduce the problems of lead belt shaking and deviation, thereby improving the stability and continuity of the lead belt conveying.

[0018] The adjustable structure of the pressing force of the lower pressing plate ensures that the lead belt does not loosen or slip during the conveying process, ensures the accuracy of the conveying, and avoids the deformation or damage of the lead belt caused by excessive pressing force, thereby improving the product quality and the reliability of the equipment.

[0019] The threaded adjusting member at the position of the upper feeding roller makes the adjustment of the gap between the feeding rollers simple and accurate, can quickly adapt to lead belts of different thicknesses, improves the versatility and flexibility of the equipment, and improves the production efficiency without complex operation and long shutdown adjustment.

[0020] The driving device drives the relaxation cam to rotate, and the roller engages to make the slide slide up and down. In continuous feeding, when there is a small error in feeding, such as speed or position deviation, the specific profile curve of the relaxation cam makes the roller produce corresponding displacement, which is converted into the up-down movement of the slide, and then the pressure or position of the lead belt is adjusted through the fixing member and the lower pressing plate to compensate for the error and prevent error accumulation. Since the rotation of the relaxation cam is periodic, every time it rotates one circle, its engagement with the roller will make the feeding mechanism return to the initial or standard state at a certain time, achieving periodic reset and calibration. When the cam rotates to a certain position, the driving roller makes the feeding part return to the accurate starting position or perform accurate calibration, thereby eliminating the accumulated error in the previous continuous feeding process.

[0021] Further, the lower end of the adjusting screw is provided with a reset spring which is connected with the adjusting screw. During the adjustment of the adjusting screw, the spring can absorb and relieve the instantaneous impact force that may be generated, thereby avoiding damage to the entire adjustment mechanism caused by sudden or violent adjustment actions, and protecting the structural integrity and stability of the equipment. When the adjusting screw is deviated from the set value due to external interference or abnormal conditions, the reset spring can pull or push the adjusting screw back to the initial or preset position by its elastic restoring force, ensuring that the pressing force of the lower pressing plate on the lead belt can quickly recover to the normal state.

[0022] Further, an adjusting rod is provided between the lower pressing plate and the fixing member to adjust the position of the lower pressing plate. By changing the length or angle of the adjusting rod, the relative position of the lower pressing plate and the lead belt can be controlled to ensure that the pressing force on the lead belt is uniform and moderate, which is beneficial to improve the feeding accuracy and stability.

[0023] Further, the upper feeding compression roller and the lower feeding compression roller are arranged in an up-down adjustable structure, by adjusting the relative position of the upper feeding compression roller and the lower feeding compression roller, the lead belt of various thicknesses can be adapted, without needing to equip special feeding compression rollers for each thickness of lead belt, thereby reducing the equipment cost; the compression force on the lead belt can be ensured to be always in a proper range, for thinner lead belt, the distance between the compression rollers is appropriately reduced to provide sufficient compression force, preventing the lead belt from slipping during the conveying process; for thicker lead belt, the distance is increased, avoiding that the lead belt is deformed or damaged due to excessive compression force.

[0024] Further, a plurality of blocking wheels are arranged between the upper feeding compression roller and the lower feeding compression roller, the rotating direction of the blocking wheels is consistent with the conveying direction of the lead belt, since the lead belt may be laterally moved due to various factors during the conveying process, the blocking wheels consistent with the conveying direction can block and guide the lead belt, so that the lead belt is always kept on the correct conveying path, thereby improving the accuracy and stability of the conveying, no matter how the width of the lead belt changes, the blocking wheels can limit the lateral movement of the lead belt to a certain extent, ensuring the universality of the equipment when processing lead belts of different specifications.

[0025] Further, the upper feeding compression roller and the lower feeding compression roller are arranged on different parallel planes respectively, the distance between the upper and lower compression rollers can be flexibly adjusted according to the thickness of the material, without replacing the whole set of devices, the feeding requirements of materials of various thicknesses can be met, the universality and production efficiency of the equipment are improved, and the cost is reduced.

[0026] Further, the blocking wheels are arranged in a horizontally slidable adjusting mode, the horizontally slidable adjusting blocking wheels can be adjusted in position according to the actual width of the lead belt, so that the lead belt of various widths can be effectively guided and limited, and the universality of the equipment is improved.
