This invention provides an automatic positioning and drilling device and method for metal castings, comprising: a frame with a worktable at its bottom and a support column extending above the worktable connected to the top of the frame; a drilling assembly mounted on the support column for drilling holes in the casting; and a linear adjustment assembly mounted on the worktable for positioning the casting. This disclosure belongs to the technical field of drilling equipment. Through its clamping assembly, this invention allows for continuous drilling operations on multiple different planes of the metal casting using pneumatic pressure after clamping it. The forward movement of the rotating component drives the adjustment shaft to rotate, thereby causing the chuck to rotate with the metal casting. This allows for continuous drilling operations on multiple different planes of the metal casting with a single clamping, significantly improving the drilling efficiency of metal castings.

This invention relates to a coconut opener, comprising a shell assembly; an opening mechanism for opening holes in coconuts; the opening mechanism includes an opening cutter for cutting the coconut, an opening lever arm for moving the opening cutter along a predetermined opening trajectory, and an opening drive assembly; the opening drive assembly is driveably connected to the opening lever arm, and drives the opening lever arm to move relative to the coconut; the opening cutter is disposed on the opening lever arm, and the opening lever arm drives the opening cutter to move along the opening trajectory on the coconut; the opening drive assembly is driveably connected to the opening cutter, and drives the opening cutter to perform cutting activities on the coconut; the opening drive assembly is electrically connected to a control module; and a clamping mechanism is used to clamp the coconut, at least during the opening process; the opening mechanism and the clamping mechanism are respectively disposed on the shell assembly. This coconut opener can open large-area holes in coconuts, facilitating the extraction of coconut juice and coconut meat, and its overall size is compact.

The utility model provides a kind of treepaper carton processing trepanning device, by first conveyor belt, trepanning mechanism, second conveyor belt sequentially arranged along the direction of conveyance, and then the treepaper paperboard constituting carton is conveyed from first conveyor belt to trepanning mechanism and is trepanned, after being sent out by second conveyor belt, realize the full automation of treepaper paperboard, trepanning and discharging processing, to improve the trepanning efficiency when treepaper carton is processed, improve economic benefits.Simultaneously, by setting dust hood to be sleeved outside output assembly, avoid the dust generated when trepanning to be scattered to working environment and be inhaled by human body, cause damage to the health of operator;Simultaneously set negative pressure fan to carry out suction treatment to dust emitted in dust hood in time by suction pipe and dust suction pipe, avoid too much dust to overflow to dust hood outside or dust to deposit on conveying assembly, cause conveying assembly to be blocked and damaged, guarantee the use safety and use efficiency of device, improve service life.

The flame-heated, heat-melting type mulch film opening and removal device belongs to agricultural machinery. It features a fixed connector, a push-button ignition switch, and a flame nozzle on a tubular handle. A gas cylinder connects to the tubular handle cavity via the connector. A fixed flame shield is fitted over the flame nozzle. A grooved wheel-shaped cylindrical cutter holder is fixed to the end of the flame shield. Multiple arc-shaped melting film cutters are axially movable on the grooved wheel-shaped cylindrical cutter holder via a cutter rod, a limit block, and a pressure spring. These arc-shaped melting film cutters are arranged in a circular hole configuration. An inverted conical film-removing needle is fixed inside the grooved wheel-shaped cylindrical cutter holder, located on the inner side of the arc-shaped melting film cutters. This device uses a heat-melting method to complete the opening operation on the mulch film. It features a novel, unique, and reasonable structure, labor-saving, time-saving, high opening efficiency, good quality, reliable film removal, and strong adaptability.

This utility model provides a punching device for producing cured meat, including a base, a mounting frame on the base, and a movable rod and a return spring abutting the movable rod on the mounting frame. The movable rod is vertically mounted on the mounting frame and located above the base. A punching needle is provided on the side of the movable rod near the base. The return spring abuts against the movable rod and drives it to move away from the base. The mounting frame also has a rotatable pressure rod with a protrusion that abuts against the end of the movable rod away from the base. When the pressure rod rotates, the protrusion pushes the movable rod towards the base. This utility model solves the technical problem of laborious and inefficient manual punching of pork pieces, resulting in labor saving and improved punching efficiency. Furthermore, it is simple to operate and avoids worker hand injuries during the punching process.
