Description

Technical field:

[0001] The utility model relates to the technical field of profile sawing, in particular to an automatic, efficient, precise and continuous feeding device specially designed for a double-head saw. Background technology:

[0002] A double-head saw is a tool used for cutting profiles in the production of doors and windows. It primarily consists of a bed with a guide rail. A fixed saw head (also called the left saw head) is fixed to one end of the bed, while a movable saw head (also called the right saw head) is mounted on the guide rail. The left and right saw heads work together to cut profiles. For details on their structure, please refer to the double-head saw cutting machine assembly disclosed in the Chinese patent publication (Grant Announcement No.: CN212599349U).

[0003] In order to facilitate feeding in actual applications of double-head saws, the existing technology usually sets a support rack on the right side of the movable saw head, and multiple support rods are set at intervals on the support rack. When feeding, the profile can be pushed or pulled manually to quickly move the profile for feeding. The setting of the support rods changes the sliding feeding of the profile into rolling feeding, which saves manpower and improves feeding efficiency to a certain extent. However, the technical effect brought by relying solely on the support rods is limited. Not only does it still require manual operation, but the manual feeding accuracy is poor. Usually, in order to ensure that the left saw head can cut the profile, the feeding distance is often too long, which results in longer sawed waste and a waste of resources. Therefore, it is necessary to optimize and improve the existing technology in order to design an automatic, precise and continuous feeding solution suitable for double-head saws.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility model content:

[0039] Instructions for use of the automatic, efficient, precise and continuous feeding device of this application:

[0040] When feeding, the pushing cylinder 403 contracts first, thereby driving the slide 402 and the automatic feeding mechanism 5 on it to move a short distance away from the support plate 6, and then the front end of the profile is placed between the driven wheel group 506 and the driving wheel group 505, and the clamping cylinder 504 is started. The clamping cylinder 504 drives the clamping slide 503 to move toward the driving wheel group 505, and the two driven pressure rollers 5063 on the clamping slide 503 clamp the profile longitudinally on the active pressure roller A5054 and the active pressure roller B5162, and then the servo motor 511 is started. The servo motor 511 drives the active pressure roller A505 through the reducer 510, the coupling 508 and the active wheel shaft A5052 4 rotates. At the same time, the driving wheel shaft A5052 drives the driving wheel shaft B5160 and the driving pressure wheel B5162 to rotate synchronously through the synchronous pulley A5053, the synchronous belt 5163 and the synchronous pulley B5161. Under the joint rotation of the driving pressure wheel A5054 and the driving pressure wheel B5162, the profile is driven to be transported and fed (i.e., fed). The feeding length is precisely controlled by the servo motor 511. After feeding is completed, the push cylinder 403 resets and drives the profile to move toward the side of the support plate 6. Then, the clamps on the left and right saw heads 1 (existing technology) clamp the profile, and then sawing is carried out. After sawing is completed, the above steps are repeated to continue sawing the profile. The technical solution of the present application realizes automatic, precise, efficient and continuous feeding of profiles.
