[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a waste collection device for corrugated cardboard edge trimming, including an edge trimming table 1 for trimming excess material from the side of the corrugated cardboard, a collection channel 3 located on one side of the edge trimming table 1, and a collection mechanism 4 connected to the collection channel 3. The edge trimming table 1 is equipped with a guide block 2 to guide the waste into the collection channel 3.

[0023] After the corrugated cardboard is trimmed of the side waste on the cutting table 1, it enters the collection mechanism 4 through the collection channel 3.

[0024] The guide block 2 is located at the front end of the collection channel 3. The guide block 2 includes two fixed blocks, one of which has an arc-shaped side to facilitate guiding waste into the collection channel 3.

[0025] The material collection channel 3 is equipped with a crushing mechanism 35 for chopping waste. The crushing mechanism 35 includes two support plates 351 connected to the inner wall of the crushing pipe 33. A rotating shaft 353 is rotatably installed between the two support plates 351. A motor 352 is installed on one of the support plates 351. The output shaft of the motor 352 is connected to the rotating shaft 353.

[0026] The outer wall of the rotating shaft 353 is fitted with a plurality of collars 354, and the outer wall of the collars 354 is connected to a plurality of crushing blades 355.

[0027] Motor 352 drives shaft 353 to rotate, shaft 353 drives collar 354 and crusher 355 to rotate, thereby crushing waste.

[0028] The material collection mechanism 4 includes a material collection cylinder 41 connected to the material collection channel 3. A platform 5 is installed on the upper side of the material collection cylinder 41. An exhaust fan 6 is installed on the platform 5 to provide airflow for the material collection channel 3. The exhaust fan 6 draws air from the material collection channel 3 to generate airflow, which can draw waste material into the interior of the material collection channel 3.

[0029] The inside of the collection cylinder 41 is equipped with a pressing mechanism for compacting waste material, which can be raised and lowered to compact the loose waste material, save space inside the collection cylinder 41, ensure that more waste material is collected, and avoid the frequent operation of taking out waste material from the collection cylinder 41.

[0030] Specifically, the lower side of the collecting cylinder 41 has a discharge port, and two opposing door plates 42 are rotatably installed on the discharge port to facilitate the removal of the compacted waste material.

[0031] The material collection channel 3 includes a material collection hopper 31, a main pipe 32, and a discharge pipe 34 arranged in sequence. The inner bottom of the material collection hopper 31 is flush with or lower than the surface of the cutting table 1 to prevent waste material from entering the material collection channel 3. The material collection hopper 31 is connected to the cutting table 1. The side of the material collection cylinder 41 is provided with a feed inlet 43, and the discharge pipe 34 is inserted into the inside of the feed inlet 43.

[0032] The discharge pipe 34 is curved at a certain arc, which can directly guide the waste into the bottom of the collection cylinder 41.

[0033] A section of crushing pipe 33 is provided in the middle of the main pipe 32, and the crushing mechanism 35 is installed inside the crushing pipe 33. The waste material is crushed as it moves forward.

[0034] The pressing mechanism includes two symmetrically arranged sleeves 45 and a lifting pressure plate 44. The two sleeves 45 are symmetrically arranged about the center of the collecting cylinder 41, and two connecting blocks 48 are connected to the side of the pressure plate 44.

[0035] One of the sleeves 45 has a lead screw 47 rotatably mounted inside, and a second motor 46 for driving the lead screw 47 to rotate is mounted on the top of the sleeve 45, i.e., the output shaft of the second motor 46 is connected to the top of the lead screw 47. A round rod 49 is fixed inside the other sleeve 45. One of the connecting blocks 48 is threaded to the outer wall of the lead screw 47, and the other connecting block 48 is slidably sleeved on the outer wall of the round rod 49.

[0036] It should be noted that slots are provided on the outer walls of the two sleeves 45 at opposite positions, and the end of the connecting block 48 passes through the slots and connects to the pressure plate 44.

[0037] Motor 46 drives lead screw 47 to rotate. With the cooperation of round rod 49, lead screw 47 drives pressure plate 44 to move down through two connecting blocks 48.

[0038] When in use, place the corrugated cardboard on the cutting table 1, and use the feeding device and pressing device on the cutting table (the feeding device and pressing device are common structures in the existing technology and will not be described in detail here. The feeding device drives the corrugated cardboard forward, and the pressing device ensures the stability of the corrugated cardboard forward) to drive the corrugated cardboard forward stably, and use the cutter (located above the cutting table 1) to cut off the uneven sides of the corrugated cardboard.

[0039] When the air pump is running, the cut-off waste material ends abut against the guide block 2. The air pump draws air from the collection channel 3, causing airflow in the collection channel 3. The cut-off waste material is then drawn into the collection channel 3. The crushing mechanism 35 of the crushing pipe 33 crushes the waste material. Specifically, the motor 352 drives the rotating shaft 353 to rotate, and the rotating shaft 353 drives the collar 354 and the crushing blade 355 to rotate, thereby crushing the waste material. This facilitates the drawing of the waste material into the collection cylinder 41. Then, driven by the airflow, the waste material enters the collection cylinder 41 through the discharge pipe 34.

[0040] When the waste material in the collection cylinder 41 is collected to about half its height, the pressing mechanism is activated. Motor 2 46 drives the lead screw 47 to rotate. With the cooperation of the round rod 49, the lead screw 47 drives the pressure plate 44 to move down through two connecting blocks 48, compacting the loose waste material and saving space in the collection cylinder 41. This ensures that more waste material is collected and avoids the frequent removal of waste material from the collection cylinder 41.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
