Description

Technical Field

[0001] This invention relates to a stainless steel pipe processing equipment, and more particularly to a stainless steel pipe discharge device. Background Technology

[0002] In daily life, steel pipes are widely used in all aspects of daily life, and stainless steel pipes are particularly popular due to their strong corrosion resistance and aesthetic appeal. The manufacturing process of stainless steel pipes involves conveying stainless steel strips of a certain specification to a production line via a rotating shaft. On the production line, the stainless steel strips are gradually rolled into round pipes. These round pipes are then welded, cooled, and shaped, followed by grinding and polishing, and finally cut into sections to form individual steel pipes. The production process of stainless steel pipes requires several discharge devices to receive the processed stainless steel pipes and facilitate their transfer between different workstations.

[0003] The discharge device includes a base, a triggering component, and several sets of bearing platforms. These bearing platforms are arranged at intervals, with the triggering component located at one end of the platform arrangement. Each bearing platform set includes a left bearing wheel rotatably mounted on the base and a right bearing wheel slidably mounted on the base and reciprocating towards the left bearing wheel. A right control component is mounted on the base to synchronously control the movement of the right bearing wheels. A left control component is located between the triggering component and the left bearing wheels to control their movement. Existing right and left control components use multiple drive sources for precise synchronous control of the left and right bearing wheels. However, this multiple drive source setup significantly increases the production cost of the discharge device. Furthermore, a failure in one drive source interferes with the normal operation of the others, leading to a high failure rate and impacting product processing efficiency. Additionally, the fixed position of the existing triggering component makes it unsuitable for triggering actions on pipes of different lengths, resulting in poor versatility. Summary of the Invention

[0004] The purpose of this invention is to provide a stainless steel pipe discharge device, which has a simple structure, low failure rate, good versatility, and ensures product processing efficiency.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a stainless steel pipe discharge device, comprising a base, a trigger plate disposed on the base, and several bearing platforms, wherein the several bearing platforms are arranged at intervals, each bearing platform comprising a left bearing wheel hinged to the base and a right bearing wheel slidably disposed on the base and reciprocating toward the left bearing wheel, and a placement area for placing stainless steel pipes is formed between the left and right bearing wheels, and a one-way limiting component is provided between each right bearing wheel and the base to restrict the movement of the right bearing wheel away from the left bearing wheel, and a right control rod is slidably disposed on the base. A right linkage component is provided between the right control lever and each one-way limit component. The right control lever realizes synchronous control of several one-way limit components through each right linkage component. A first return spring is provided between each left bearing wheel and the base to drive the left bearing wheel to rotate to the right bearing wheel side. The base is provided with a positioning component for positioning each left bearing wheel, and the positioning component positions the left bearing wheel and the right bearing wheel to form a placement area. The trigger plate is located at one end of the bearing platform arrangement direction and is reciprocated along the bearing platform arrangement direction. A docking component is provided between the trigger plate and the positioning component to enable the trigger plate to trigger the positioning component to act.

[0006] By adopting the above technical solution, the sliding trigger plate is adjusted to a position suitable for the length of the stainless steel pipe being processed, according to the different lengths of the stainless steel pipe. Then, the docking assembly is used to connect the trigger plate and the positioning assembly. After processing, the stainless steel pipe is transported along its axis to the placement area and positioned above the left and right bearing rollers. When one end of the transported stainless steel pipe contacts the trigger plate, the trigger plate drives the positioning assembly to release the positioning assembly from the left bearing roller, causing several left bearing rollers to rotate synchronously downwards around the hinge, thus completing the discharge rolling of the stainless steel pipe and completing the discharge operation. The right control lever synchronously controls the one-way limit assembly through the right linkage assembly to release the restriction on the right bearing roller, allowing several right bearing rollers to slide synchronously towards or away from the left bearing roller, thereby adjusting the distance between the left and right bearing rollers and changing the size of the placement area to accommodate stainless steel pipes of different diameters. The use of a drive source is avoided through the linkage control between simple structures. This structure is simple, has a low failure rate, good versatility, and ensures product processing efficiency.

[0007] The unidirectional limiting component is further configured as follows: the eccentric limiting block is hinged to the right bearing wheel, a driving spring that drives the eccentric limiting block to press against the base, and a friction pad that is fixedly disposed at the position where the eccentric limiting block abuts against the base.

[0008] By adopting the above technical solution, the drive spring drives the eccentric limiting block to rotate eccentrically around the hinge to make the friction pad press against the base. The friction between the friction pad and the base realizes the unidirectional limiting of the right bearing wheel. When the friction pad separates from the base, the right bearing wheel can slide.

[0009] The configuration is further defined as follows: each right linkage component includes a linkage main rod connected to the right control rod, a linkage support rod fixedly disposed on the linkage main rod and corresponding to the one-way limiting component, and a linkage hole formed on the eccentric limiting block and cooperating with the linkage support rod. The linkage hole includes a first linkage segment and a second linkage segment, and the linkage support rod reciprocates between the two. When the linkage support rod is located in the first linkage segment, the friction pad contacts the base; when the linkage support rod is located in the second linkage segment, the friction pad separates from the base.

[0010] By adopting the above technical solution, the right control rod controls the movement of the linkage support rod between the first linkage section and the second linkage section through the linkage main rod. When the linkage support rod is located in the second linkage section, the friction pad separates from the base. At this time, dragging the right control rod can drive several right bearing wheels to achieve synchronous movement. The structure is simple and the operation is convenient.

[0011] Further configuration includes a guide spherical surface fixedly mounted on the linkage support rod and a mating inclined surface mounted on the inner wall of the second linkage section and cooperating with the guide spherical surface.

[0012] By adopting the above technical solution, the linkage rod drives the guide spherical surface to move towards the mating inclined surface. By guiding the spherical surface and the mating inclined surface together, the direction of the force is changed, thereby driving the friction pad to move back towards the base.

[0013] The positioning assembly is further configured as follows: the positioning component includes a positioning linkage that is movably set, a positioning block located below each left bearing wheel, a connecting rod between each positioning block and the positioning linkage that synchronously controls several positioning blocks to leave or enter below the left bearing wheel during the movement of the positioning linkage, and a second return spring that connects the positioning linkage to reset the positioning block to below the left bearing wheel.

[0014] By adopting the above technical solution, the positioning linkage drives the positioning block to enter or leave under the left bearing wheel through the connecting rod. When the positioning block is under the left bearing wheel, the positioning block restricts the left bearing wheel from rotating away from the right bearing wheel, thereby realizing the positioning of the left bearing wheel.

[0015] The assembly is further configured such that the docking component includes a docking groove that moves with the trigger plate and is used for docking with the positioning rod, and a locking member that connects the docking groove and the positioning rod, wherein the positioning rod is located within the docking groove.

[0016] By adopting the above technical solution, the position of the docking slot on the positioning rod is adjusted by moving the trigger plate. When it is adjusted to the appropriate position, the locking part is used to lock it to realize the docking of the trigger plate and the positioning rod.

[0017] A further configuration is provided: a limit plate is fixedly installed at the position directly above the positioning block for each of the left bearing wheels.

[0018] By adopting the above technical solution, the setting of the limiting plate avoids interference between the left bearing wheel and the positioning block during rotation, thus ensuring the stable operation of the structure.

[0019] Further configuration: a feeding slope is provided on the side of the base near the left bearing wheel; a packaging roller and a control motor for controlling the rotation of the packaging roller are provided above the feeding slope; a pressing strip and a first driving member for driving the pressing strip to reciprocate toward the feeding slope are provided on the feeding slope below the packaging roller; a pressing strip and a second driving member for driving the pressing strip to reciprocate toward the feeding slope are provided behind the pressing strip on the feeding slope; a through groove extending along its length is provided on the pressing strip; a heating sealing strip that cooperates with the feeding slope and a third driving member for driving the heating sealing strip into the through groove are provided above the through groove; a heating cutting wire and a fourth driving member for driving the heating cutting wire to move are provided on the side of the pressing strip near the packaging roller.

[0020] By adopting the above technical solution, the packaging film roll is fixedly installed on the packaging roller. The control motor controls the rotation of the packaging roller to unwind the packaging film roll. One end of the unwound packaging film falls to the discharge slope under the action of gravity and then moves along the discharge slope towards the edge pressing strip. Then, the first drive component drives the edge pressing strip to press and fix that end of the packaging film. The stainless steel tube in the placement area rolls down from the discharge slope under the action of the left bearing wheel and enters the space between the discharge slope and the packaging film. The packaging film cushions the fall of the stainless steel tube, preventing collisions and ensuring product quality. The stainless steel tube continues to move downward with the packaging film. When the stainless steel tube passes the edge pressing strip, the packaging film forms a U-shape under the action of the stainless steel tube. Then, the second drive component drives the pressing strip to press the packaging film. Then, the third drive component drives the heating sealing strip to achieve heat sealing of the packaging film. Finally, the fourth drive component, in conjunction with the heating cutting wire, completes the cutting of the packaging film. This structure completes the packaging process while the stainless steel tube is being unwound, and the packaging process also cushions the unwound stainless steel tube, preventing damage from impact with the ground.

[0021] In summary, the present invention has the following advantages: the present invention has a simple structure, low failure rate, good versatility, and ensures product processing efficiency. Attached Figure Description
