Description

Technical Field

[0001] The present application relates to the technical field of belt processing equipment, and in particular to a belt punching machine. Background Art

[0002] Belts, as an indispensable accessory in daily wear, play an important role in fixing pants and shaping waistlines. They not only ensure that the wearer can move freely and comfortably, but also can be cleverly integrated into the overall shape, enhance the dressing taste, and enable the wearer to confidently and appropriately show personal style and charm.

[0003] In the related technology, a belt usually consists of three parts: a belt body, a buckle and a buckle head. The belt body is the main part, and the material is leather, which is designed to meet the needs of wearing in different occasions and styles. The holes evenly opened on the belt body are convenient for adjusting the length, adapting to different waist circumferences, and ensuring the comfort and fit of wearing. At present, most belt manufacturers still rely on manual operation in the belt body punching process, using a hole needle to punch holes one by one.

[0004] The above-mentioned punching method is not only inefficient and difficult to meet the urgent needs of modern industrial production for efficiency and automation, but also may cause problems with punching position deviation during the punching process, which often affects the overall quality and aesthetics of the product, becoming a key factor restricting the improvement of belt production efficiency and quality. There is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a belt punching machine to solve the problem of low belt punching efficiency in the above-mentioned related technologies.

[0006] The present application provides a belt punching machine that adopts the following technical solution: A belt punching machine comprises a base, a punching member for punching holes in the belt and a traction member for driving the belt to feed, wherein guide plates are arranged side by side on the base, and a plurality of guide wheels are arranged on both guide plates, and guide ring grooves for the belt edges to be inserted into the outer peripheries of the guide wheels are provided; the punching member comprises a support arm fixedly mounted on the base and a punching cylinder mounted on the support arm in a vertical direction, a punching rod located between the two guide plates is fixedly mounted at the end of the telescopic rod of the punching cylinder, and a support rod located directly below the punching rod is fixedly mounted on the base.

[0007] By adopting the above technical solution, during the belt punching process, the belt is fed by the traction member, and at the same time, the two opposite edges of the belt are inserted into the guide ring groove. When the part of the belt that needs to be punched moves to just below the punching rod, the punching cylinder is started to drive the punching rod to slide downward, thereby opening corresponding holes on the belt; thereby, the automated hole opening processing of the belt is realized, the hole opening efficiency is guaranteed, and it can meet the needs of mass production.

[0008] Optionally, the traction member includes an active roller and a driven roller rotatably arranged above a base, the active roller and the driven roller are arranged side by side, the driven roller is located above the active roller, a traction gap is preset between the active roller and the driven roller for the belt to be inserted, and a traction motor is fixed on the base to drive the active roller to rotate.

[0009] By adopting the above technical solution, during the operation of the traction part, the belt is inserted into the traction gap in advance, and then the traction motor is started to drive the active roller to rotate, thereby driving the traction feeding of the belt; by controlling the speed of the traction motor, the feeding speed of the belt can be accurately adjusted, thereby realizing accurate control of the punching position and the punching spacing. This is crucial to ensure product quality and meet specific production needs.

[0010] Optionally, the two guide plates are slidably arranged on the side surface of the base, and the base is provided with an adjusting member which drives the two guide plates to slide back and forth in a direction approaching each other.

[0011] By adopting the above technical solution, the distance between the two rotating wheels can be adjusted to meet the feeding guide of belts with different widths.

[0012] Optionally, the adjusting member includes an adjusting motor fixed on the base, an adjusting screw coaxially fixedly connected to the output shaft of the adjusting motor, the adjusting screw is provided with threads with opposite rotation directions, and the two guide plates are coaxially provided with adjusting screw holes for the adjusting screws to be screwed into.

[0013] By adopting the above technical solution, the rotation of the adjusting screw can be precisely controlled by adjusting the rotation of the motor, thereby driving the two guide plates to slide in the direction of approaching or moving away from each other. Since the adjusting screw is provided with threads with opposite rotation directions, and the guide plate is provided with matching adjusting screw holes, it is possible to ensure that the two guide plates move relatively at the same speed, thereby achieving the purpose of precisely adjusting the spacing.

[0014] Optionally, an extrusion piece is symmetrically provided on the side surface of the base around the outer circumference of the support rod, and the extrusion piece includes an extrusion rod slidably provided on the base, a power piece driving the extrusion rod to slide toward the direction close to the support rod, and a first reset piece driving the extrusion rod to reset in the opposite direction. An extrusion plate is fixedly provided at the end of the extrusion rod close to the support rod, and an extrusion groove is provided on the extrusion plate, the inner wall of which can be tightly pressed against the outer circumference of the support rod.

[0015] By adopting the above technical solution, when the hole punching machine is running, the power piece drives the extrusion plate and the extrusion plate to slide in the direction close to the support rod until the inner wall of the extrusion groove abuts against the outer peripheral surface of the support rod, thereby improving the installation stability of the support rod and reducing the possibility of the support rod being loosened when the punching rod is punching the support rod.

[0016] Optionally, the power part includes a power rod fixed to the end of the extrusion rod away from the support rod, and an adjustment rod is vertically fixed on the side surfaces of the two guide plates close to each other, and a guide slope is provided on the end edge of the adjustment rod; when the adjustment rod slides with the guide plate, it can squeeze the power rod and the extrusion rod along the guide slope, so that the inner wall of the extrusion groove is tightly pressed against the outer peripheral surface of the support rod.

[0017] By adopting the above technical solution, due to the combined arrangement of the adjusting rod and the power rod, when the two guide plates slide toward each other, the adjusting rod can squeeze the power rod and the extrusion rod along the guiding inclined surface, so that the inner wall of the extrusion groove is tightly pressed against the outer peripheral surface of the support rod; when the adjusting rod and the power rod are misaligned, the first reset member presses against the power rod, so that the extrusion rod and the extrusion plate are reset, and the limiting pressure on the support rod is released.

[0018] Optionally, the first reset member includes a first compression spring and a limit block fixed on the side of the base, the limit block is provided with a limit through hole for the extrusion rod to pass through and slide, and the two ends of the first compression spring are respectively fixedly connected to the side surfaces of the limit block and the power rod that are close to each other.

[0019] By adopting the above technical solution, when the adjustment rod and the power rod are misaligned, the first compression spring can use its elastic restoring force to push the power rod and the extrusion rod to slide away from the support rod, so that the extrusion plate and the inner wall of the extrusion groove are separated from the outer peripheral surface of the support rod, thereby achieving automatic reset.

[0020] Optionally, the support rod is provided with a material dropping hole for waste formed by stamping to fall into, the base is provided with a collecting chamber connected to the material dropping hole, the vertical side of the base is provided with an opening connected to the collecting chamber, and the collecting chamber is provided with a collection drawer for waste to be placed in.

[0021] By adopting the above technical solution, when the belt is subjected to hole drilling processing, the punching rod punches in the direction close to the support rod and is inserted into the blanking hole, so that the waste formed by the punching falls into the blanking hole, and the waste can fall into the collection drawer along the blanking hole; thereby realizing the automatic collection of stamping waste.

[0022] Optionally, a locking member is provided on the outside of the base, and the locking member includes a locking plate slidably arranged on the vertical side surface of the base, a second reset member that drives the locking plate to slide downward to lock the collection drawer, and a control member that drives the locking plate to slide upward to unlock the lock; the control member includes a control rod fixedly arranged on the side surface of the locking plate, a bending rod located above the base is fixedly arranged on the upper end of the control rod, the lower side surface of the bending rod can abut against the upper side surface of the base, a positioning rod is fixedly arranged on the guide plate, and a guide inclined surface is provided on the end edge of the positioning rod; when the positioning rod slides with the guide plate, the bending rod can be squeezed along the guide inclined surface to make the bending rod slide in a direction away from the base.

[0023] By adopting the above technical solution, the design of the locking part effectively prevents the collection drawer from being accidentally pulled out during the operation of the belt punching machine, thereby avoiding the scattering of waste and possible safety hazards. This is crucial to ensure the safety of operators and the stable operation of the equipment; when the punching machine is running, the collection drawer is locked to prevent unauthorized persons from pulling out the collection drawer when the machine is turned on and off, reducing the impact on waste collection; when the machine stops running, the locking plate moves up under the action of the positioning rod, and the collection drawer can be unlocked at this time, so that the collection drawer can be taken out to clean the waste inside.

[0024] Optionally, the second reset member includes a second compression spring and a fixed block fixed on the vertical side of the base, the fixed block is provided with a fixed through hole for the control rod to pass through, and the two ends of the second compression spring are respectively fixedly connected to the side surfaces of the locking plate and the fixed block close to each other.
