Description

Technical Field

[0001] The utility model belongs to the technical field of PU synchronous belt production, and specifically relates to a slitting mechanism for PU synchronous belt production. Background Art

[0002] PU timing belt, also known as polyurethane timing belt, is a transmission system component widely used in various industrial fields. It is made of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compounds by addition polymerization; the slitting mechanism is one of the key equipment in the production process of PU timing belt, which is responsible for accurately cutting the produced long strips of PU timing belt material according to the predetermined width and length to meet the needs and application scenarios of different customers.

[0003] Currently, in the slitting process of PU synchronous belts, the spacing of the slitting blades on the slitting device is set to a fixed value. This design greatly limits its adaptability and flexibility. Since the specifications and sizes of synchronous belts are diverse, ranging from narrow to wide, from thin to thick, and the existing slitting equipment cannot accurately adjust and cut according to these different needs, this fixed spacing slitting method undoubtedly brings many inconveniences to production. On the one hand, it limits the cutting range of synchronous belts, making it impossible to effectively process synchronous belts of certain specifications; on the other hand, due to the inability to cut accurately, it is also easy to cause material waste and product quality degradation, so there is room for improvement. Utility Model Content

During slitting, impurities that fall or adhere to the slitting shaft can be purged, and the impurities can be collected by the collecting part. During cleaning, the purging airflow is controlled to avoid excessive airflow blowing impurities to the outside.

[0006] Preferably, the surface of the slitting shaft is provided with threaded portions at equal intervals, the limiting member is an internal threaded ring, at least two internal threaded rings are provided on each threaded portion, the slitting blade is located between the two internal threaded rings, and the position of the slitting blade is limited by the internal threaded ring. At the same time, the internal threaded ring can be rotated according to the slitting requirements of the PU synchronous belt to achieve the adjustment of the position of the slitting blade.

[0007] Preferably, the blowing part includes an air pipe and a nozzle arranged on the air pipe in an inclined state. The nozzle is arranged in a region corresponding to the threaded part and is inclined upward in the direction of the cutting axis for blowing away impurities adhering to the threaded part.

[0008] Preferably, a mounting hole is opened at the rear of the outer frame, which is located obliquely below the slitting axis. The air pipe passes through the mounting hole, and the air supply end of the air pipe bends and extends toward the rear of the outer frame to avoid horizontally extending outward and affecting the layout of other external equipment.

[0009] Preferably, the collecting part is installed inside the outer frame, and the collecting part is a material receiving trough. The material receiving trough is located below the slitting shaft, and the width of the material receiving trough is greater than the diameter of the slitting shaft, so as to better collect impurities.

[0011] Preferably, a discharge shaft is also installed on the top of the outer frame through a bearing seat, and the PU synchronous belt cut by the slitting blade is rolled up and placed by an external winding device through the discharge shaft.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the designed adjustment component, the position of the slitting blade can be flexibly adjusted according to the different size specifications of the PU synchronous belt. No matter whether it is a narrow or wide synchronous belt, the slitting blade can be accurately positioned through simple operation, which greatly improves the adaptability and flexibility of the slitting mechanism and enables it to meet diverse production needs. At the same time, the adjustment component can achieve precise cutting, material waste is effectively controlled, production costs are reduced, and the shortcomings of the existing mechanism in use are improved.
