Description

Technical Field

[0001] The utility model relates to a matching device for a metal profile production line, in particular to a metal profile pretreatment device. Background Art

[0002] Metal profiles have important applications in all walks of life, especially in the field of home decoration. For example, aluminum alloy plates have high mechanical strength and strong weather resistance and are very popular in the market. When metal profiles are used in home environments, they need to undergo a series of processing, including bending, shearing, etc., to make them meet the needs of construction. During the processing of metal profile plates, they are conveyed on the conveyor belt of the production line. Since subsequent equipment is required to continuously process the metal profiles, their position on the conveyor belt is required to be relatively fixed to ensure that the processed profiles meet the construction requirements. Metal profiles often shift during the conveyor belt transmission process. In order to correct the deviation in time to ensure subsequent production, a correction device is required. The existing correction and positioning device has a complex structure and uses a large number of electronic sensors. For small and micro enterprises, not only is the equipment cost high, but in actual application, due to the metallic properties of metal profiles, there is a lot of metal powder in the air of the entire processing workshop, which can easily cause the correction device using electronic sensors to malfunction, affecting the normal production of the enterprise; at the same time, in the processing workshop, the metal powder floating in the air can easily adsorb on the metal profiles on the conveyor belt, affecting the quality of the metal profile products.

[0003] Therefore, there is an urgent need for a new type of metal profile pretreatment device, which can stably and reliably correct the metal profiles to be processed on the conveyor belt, and has a simple structure, high stability, and low cost, which can meet the procurement and production needs of small and micro enterprises. At the same time, it can also easily handle pollutants attached to the metal profiles and improve the quality of subsequent products. Utility Model Content

At the same time, it can also easily handle pollutants attached to the metal profiles and improve the quality of subsequent products.

[0005] The utility model adopts the following technical solutions:

[0006] A metal profile pretreatment device comprises a conveyor belt for carrying metal profiles, a support arm with a long strip structure for installing the conveyor belt, a correction mechanism for correcting the metal profile is fixedly provided on the support arm; the correction mechanism comprises a mounting body fixedly provided on the support arm and having an inverted L-shaped structure, a slide rail fixedly provided on the inner side of the mounting body and arranged in a vertical direction, a slider slidably provided on the slide rail, a mounting block fixedly connected to the slider and having a square structure, a threaded rod fixedly provided on the top of the mounting block and passing through the mounting body, a compression spring sleeved on the outside of the threaded rod and abutting against the lower surface of the top of the mounting body, a positioning nut threadedly connected to the threaded rod and abutting against the lower end of the compression spring, a limiting nut threadedly connected to the threaded rod and located above the top of the mounting body, and a correction wheel fixedly provided at the bottom of the mounting block; the correction wheel is obliquely provided, and the angle between the direction of travel of the correction wheel and the support arm is 0.5 to 5 degrees.

[0007] In order to gently clean the metal profile to be processed, facilitate the smooth progress of subsequent production processes, and ultimately improve product quality, a cleaning mechanism is provided on the outer side of the support arm. The cleaning mechanism includes an air pump fixed on the outer side of the support arm and a ventilation pipe connected to the air pump. The ventilation pipe spans the metal profile to be processed, and a nozzle for spraying high-pressure air is provided on the lower surface of the ventilation pipe.

[0008] Furthermore, in order to prevent the compression spring and the positioning nut from shifting and falling off, a circular gasket is provided between the positioning nut and the compression spring, and the outer diameter of the circular gasket is larger than the widest part of the compression spring in the horizontal direction.

[0009] Furthermore, the number of limit nuts is 2. At the same time, in order to enhance the friction between the metal profile and the correcting wheel, the metal profile to be processed can effectively adhere to the inner side of the arm to achieve the purpose of positioning and meet the subsequent processing and production needs, the correcting wheel is made of soft resin.

[0010] Preferably, in order to reduce the production cost of the device and improve the replaceability of parts in the device, the threaded rod and the mounting block are fixedly connected by threads, and the mounting body and the support arm are fixedly connected by bolts.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: 1. The utility model provides a threaded rod that can move up and down and a compression spring that is sleeved outside the threaded rod, so that the mounting block always has a downward force, so that the correction wheel is close to the metal profile. At the same time, the correction wheel is arranged obliquely, so that the metal profile has a movement direction close to the inner side of the support arm during the transportation process of the production line. The setting of the compression spring can avoid excessive correction during the transportation of the metal profile, thereby achieving the positioning effect. At the same time, the structure is simple, the design is purely mechanical, the cost is low, the effect is stable, and it meets the use requirements in the harsh production environment of small and micro enterprises; 2. The utility model is provided with a cleaning mechanism for spraying high-pressure gas on the support arm, which can preliminarily clean the metal profile to be processed, facilitate the subsequent processing steps, and ultimately achieve the purpose of improving product quality.

DETAILED DESCRIPTION

[0022] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0023] See also Figures 1 to 8 A metal profile pretreatment device comprises a conveyor belt 11 for carrying a metal profile 1, a support arm 2 in a long strip structure for installing the conveyor belt 11, a correction mechanism 3 for correcting the metal profile 1 is fixedly provided on the support arm 2; the correction mechanism 3 comprises a mounting body 31 in an inverted L-shaped structure fixedly provided on the support arm 2, a slide rail 32 fixedly provided on the inner side of the mounting body 31 and arranged in a vertical direction, a slider 33 slidably provided on the slide rail 32, a mounting block 34 in a square structure fixedly connected to the slider 33, a threaded rod 35 fixedly provided on the top of the mounting block 34 and penetrating the mounting body 31, and a threaded rod 35 sleeved on the outside of the threaded rod 35. A compression spring 36 abutting against the lower surface of the top of the mounting body 31, a positioning nut 37 threadedly connected to the threaded rod 35 and abutting against the lower end of the compression spring 36, a limit nut 38 threadedly connected to the threaded rod 35 and located above the top of the mounting body 31, and a correcting wheel 39 fixed to the bottom of the mounting block 34; the angle between the moving direction of the correcting wheel 39 and the support arm 2 is 1 degree. In order to enhance the friction between the metal profile 1 and the correcting wheel 39, the metal profile 1 to be processed can effectively cling to the inner side of the support arm 2 to achieve the purpose of positioning and meet the subsequent processing and production needs. The correcting wheel 39 is made of soft resin.

[0024] At the same time, in order to gently clean the metal profile 1 to be processed, facilitate the smooth progress of subsequent production processes, and ultimately improve product quality, a cleaning mechanism 4 is provided on the outer side of the support arm 2. The cleaning mechanism 4 includes an air pump 41 fixed on the outer side of the support arm 2 and a ventilation pipe 42 connected to the air pump 41. The ventilation pipe 42 spans the metal profile 1 to be processed, and a nozzle 43 for spraying high-pressure air is penetrated on the lower surface of the ventilation pipe 42.

[0025] See also Figures 1 to 8 In order to prevent the compression spring 36 and the positioning nut 37 from shifting and falling off, a circular gasket 5 is provided between the positioning nut 37 and the compression spring 36, and the outer diameter of the circular gasket 5 is larger than the widest part of the compression spring 36 in the horizontal direction. There are two limit nuts 38 and they are superimposed on each other. In order to reduce the production cost of the device and improve the replaceability of parts in the device, the threaded rod 35 and the mounting block 34 are fixedly connected by threads, and the mounting body 31 and the support arm 2 are fixedly connected by bolts.

[0026] Working principle: Through the obliquely arranged correcting wheel 39, during the transportation process, the metal profile 1 to be processed is moved toward the support arm 2 installed with the correcting mechanism 3, so that the metal profile 1 to be processed is close to the inner side of the support arm 2. At the same time, by setting the mounting block 34 which can move up and down, when the metal profile 1 to be processed is close to the inner side of the support arm 2, due to the high mechanical strength of the metal profile 1 itself, the downward pressure of the compression spring 36 on the mounting block 34 is not enough to cause the metal profile 1 to damage the inner side of the support arm 2. When the metal profile 1 moves away from the inner side of the support arm 2 during transportation, the obliquely arranged correcting wheel 39 can pull the metal profile 1 back so that its edge is close to the inner side of the support arm 2, thereby realizing the positioning function and meeting the production needs of subsequent processes. Moreover, the device is purely mechanically designed without any electronic components and has low cost, which meets the production needs of small and micro enterprises in harsh environments and the procurement needs of low prices.

[0027] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
