Description

Technical Field

[0001] This utility model relates to the field of rolling machine technology, specifically to an automatic feeding device for the collar of a continuous rolling machine. Background Technology

[0002] The character mold is moved vertically on the outer diameter of the round tube using hydraulic or mechanical devices, and the content of the character mold is rolled onto the outer diameter of the round tube through rolling and squeezing.

[0003] CN104528369B describes an automatic loading and unloading device for a letterpress printing machine, comprising a drive component, a drive component mounting bracket, a limiting mechanism, a loading mechanism, a reset mechanism, and a unloading mechanism. The drive component controls the loading and unloading mechanisms to reciprocate up and down. The loading and unloading mechanisms are rotatably connected, and the loading mechanism is slidably connected to the drive component mounting bracket via the limiting mechanism. The reset mechanism controls the unloading mechanism to perform a reset movement. The loading and unloading mechanisms in this device combine loading and unloading during the letterpress printing process, saving time and reducing the machine's cycle time. The unloading mechanism both pushes the material out and provides some support for the material to be processed, resulting in accurate, time-efficient, and high-efficiency unloading. The limiting and reset mechanisms ensure a safe, stable, and reliable loading and unloading process. While this technical solution achieves coordinated loading and unloading, its structure is relatively complex; therefore, a simpler automatic unloading device is needed. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1-4 An automatic unloading device for a continuous rolling type machine collar includes a support plate 1 for placing the rolling type machine, a placement plate 2 for placing the collar rotatably connected above the support plate 1, the edge of the placement plate 2 protruding outwards, and a collar post 3 for engaging the collar slidably connected to the placement plate 2. Multiple collar posts 3 are arranged in a circular array. A notched ring 4 is provided above the support plate 1 below the protruding part of the placement plate 2. The notch angle of the notched ring 4 is equal to the angle between the center lines of two collar posts 3. The two sides of the notched ring 4 are chamfered. A scraper 5 is provided at the notch of the notched ring 4 to scrape off the collar. By setting the collar post 3, which can extend and retract vertically, the collar is restricted, and the collar post 3 can be driven by the notched ring 4 to descend at the scraper 5, thereby using the scraper 5 to remove the collar from the device. This solves the problem in the prior art that the collar cannot be automatically removed from the rolling type machine.

[0022] The chamfered part of the notch ring 4 has an arc angle equal to the angle between the center lines of the two sleeve posts 3. The chamfered part achieves a uniform transition from the upper surface to the lower surface of the notch ring 4. This setting provides enough space for the sleeve to move, thus ensuring that the sleeve separates from the sleeve post 3 before encountering the scraper 5.

[0023] The sleeve 3 includes a sliding column 301 that can be slidably connected to the placement plate 2 and forms a protrusion above the placement plate 2. A connecting plate 302 is fixedly installed at the bottom end of the sliding column 301. A ball head 303 that maintains contact with the notched ring 4 is fixedly installed at the bottom end of the connecting plate 302. Stepped holes 304 are opened on both sides of the upper surface of the placement plate 2 on the sleeve 3. A sliding rod 305 with a protrusion at the top is slidably connected inside the stepped hole 304. The sliding rod 305 passes through the placement plate 2 and is threadedly connected to the connecting plate 302. A return spring 306 is provided between the sliding rod 305 and the inner bottom wall of the stepped hole 304. A threaded plug 307 that restricts the upward movement of the sliding rod 305 is threadedly connected to the top of the stepped hole 304. This arrangement can restrict the up and down movement of the sleeve 3. At the same time, compared with the traditional limit guide rod system, the stepped hole 304 and the assembly of the sliding rod 305 in this application can reduce the production cost and processing accuracy of the device.

[0024] The top of the sleeve 3 is provided with a stepped groove 308. A ball ring 309 is sleeved on the bottom outer ring of the stepped groove 308. A pressure cap 310 is threaded on the top outer ring of the stepped groove 308 to restrict the up and down movement of the ball ring 309. By replacing the ball ring 309 with different diameters, it can be adapted to the collar with different inner diameters, thereby increasing the versatility of the device.

[0025] A rolling machine is installed above the support plate 1 on one side of the placement plate 2. The rolling part of the rolling machine is located above the placement plate 2. Only the telescopic part of the rolling machine is shown in the figure. By restricting the position of the telescopic part to be flush with the placement plate 2, it can be determined that the rolling part of the rolling machine can contact the collar.

[0026] The placement plate 2 includes a sleeve portion 201 connected to the drive spindle in the middle. A flat plate portion 202 is provided on the outer ring of the sleeve portion 201. The edge of the flat plate portion 202 forms a thickened protrusion 203 downward. This arrangement can ensure the strength of the placement plate 2.

[0027] In use, replace the appropriate ball ring 309 according to the inner diameter of the collar processed in this process, and connect it to the collar 3 through the pressure cap 310. By rotating the placement plate 2, the collar on the outer surface of the collar 3 can be driven to pass through the lettering machine in sequence to complete the marking. After marking is completed, the collar 3 rotates to the notch of the notch ring 4. Due to the lack of support from the notch ring 4, the collar 3 slides downward under the action of the return spring 306, so that the upper surface of the collar 3 is below the upper surface of the placement plate 2. When the collar contacts the scraper 5, it can separate the collar from the placement plate 2. Continue to rotate, and the collar 3 resets again under the pressure of the notch ring 4, and is used to load the collar.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
