Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically to a box turning machine with a buffer and guiding function. Background Technology

[0002] After being conveyed by roller conveyors, tobacco boxes filled with tobacco leaves enter the box-turning and feeding process. The boxes are lifted and rotated, causing the tobacco leaves to slide down from the frames under gravity and enter the feeding hopper. During production, the tobacco leaves are pre-compressed during frame loading, resulting in a high density within the frames. After a period of storage and stacking, the tobacco leaves within the frames tend to stick together, forming clumps. When the boxes are turned over, these clumps fall directly into the hopper. Due to the significant height difference (approximately 2000mm) between the discharge port of the turning frame and the feeding hopper, the falling process causes breakage and generates a large airflow, scattering fragments outside the hopper. This process results in a high rate of tobacco leaf breakage due to the falling leaves, and the flying fragments require immediate attention from on-site personnel. To address this technical problem, this invention provides a box-turning machine with a buffer and guiding function. Utility Model Content

[0003] The purpose of this utility model is to provide a box-turning machine with a buffer and guiding function, which can effectively prevent the breakage caused by the falling tobacco leaves during the feeding process, ensure the gentle falling of materials during the box-turning process, and reduce breakage.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A box-turning machine with a buffer and material guiding function includes a base, a box-turning plate rotatably mounted on the upper part of the base, guardrails on both sides of the box-turning plate, and a vertical post at the front end of the guardrails;

[0006] The upright is slidably provided with a first sliding sleeve, a support rod is provided between the two first sliding sleeves, a guide plate is rotatably provided on the support rod, a crossbar is provided on the first sliding sleeve, and a buffer damper is provided between the crossbar and the guide plate.

[0007] The guardrail is equipped with a clamping mechanism for holding the edge of the tobacco box.

[0008] Furthermore, the base includes a horizontal base plate and a back plate. The back plate is vertically arranged on one side of the horizontal base plate to form an "L" shape. A movable wheel is provided at the bottom of the horizontal base plate, and wall hooks are slidably provided on both sides of the back plate.

[0009] Furthermore, the back plate has holes on both sides, and wall hooks are slidably disposed in the holes, the wall hooks being in the shape of an inverted "U".

[0010] Furthermore, the flip-up panel is L-shaped, with support wheels on the bottom surface of the panel and guide rails on the base, the support wheels being located within the guide rails.

[0011] Furthermore, the upright has multiple insertion holes spaced apart, and the first sliding sleeve also has insertion holes. The first sliding sleeve and the upright are connected by screws passing through the insertion holes.

[0012] Furthermore, the flip-up plate is provided with a guide rod, which is vertically arranged and its bottom end is connected to the guardrail. A second sliding sleeve is provided at the end of the crossbar and passes through the guide rod.

[0013] Furthermore, the clamping mechanism includes a screw, a screw sleeve, and a U-shaped clamp. The screw is fixedly installed on the outside of the guardrail, and a screw sleeve is threaded onto the screw. A rotating sleeve is rotatably installed on the screw sleeve, and a third sliding sleeve is installed on one side of the rotating sleeve. A sliding rod is installed on one side of the U-shaped clamp, and the sliding rod is laterally slidably installed in the third sliding sleeve.

[0014] Furthermore, the buffer damper includes an outer frame, an adjusting screw, and a telescopic rod.

A spring is sleeved on the telescopic rod, and the two ends of the spring are respectively connected to the end of the telescopic rod and the inner side of the outer frame. Both the ends of the telescopic rod and the adjusting screw are provided with connecting parts.

[0015] Compared with the prior art, this utility model can achieve at least the following beneficial effects:

[0016] 1. The present invention is provided with a movable wheel on the base for easy movement, and a support wheel on the flip-top plate for supporting the cigarette box and preventing damage to the bottom surface of the flip-top plate. In addition, a wall hook is slidably provided on the back plate of the base so that it can be hooked on the side wall of the hopper during operation, preventing the device from moving backward due to unbalanced force during the unloading process.

[0017] 2. A clamping mechanism is provided on the guardrail to fix the edge of the tobacco box and prevent it from falling during the turning process. The U-shaped clamp of the clamping mechanism can move up and down as well as back and forth, so it is suitable for clamping tobacco boxes of different widths and heights.

[0018] 3. A first sliding sleeve is slidably installed on the upright on the front side of the guardrail, and a support rod is installed between the two first sliding sleeves. A guide plate is slidably installed on the support rod to guide and buffer the tobacco leaves, which can prevent the tobacco leaves from falling directly during the unloading process of the box tipper, ensure that the material falls gently during the unloading process, and reduce breakage. Since the first sliding sleeve is slidably installed and can be fixed by screws, the appropriate height of the guide plate can be adjusted according to the height of the tobacco box.

[0019] 4. A buffer damper is installed between the guide plate and the crossbar. The buffer damper includes an outer frame, an adjusting screw, a telescopic rod, and a spring. This allows the length of the buffer damper to be adjusted within a certain range, thereby adjusting the buffer swing angle and opening of the guide plate. Attached Figure Description
