Description

Technical Field

[0001] This utility model relates to the field of pine bar processing, and in particular to a cutting machine for Christmas tree PVC pine bars. Background Technology

[0002] PVC pine branches for Christmas tree decorations are a widely used material for creating artificial vegetation. They are typically made of PVC and feature numerous simulated needle-like structures on their surface to mimic the shape of natural pine branches. During production, continuous lengths of PVC pine branches need to be cut into segments of specific dimensions for subsequent assembly and packaging. Traditional sliver cutting methods primarily rely on manual operation or simple mechanical devices. Manual cutting is not only inefficient and labor-intensive, but also lacks precision, leading to material waste and poor product consistency. While some existing mechanical cutting equipment achieves a degree of automation, it still has many limitations: for example, most machines can only cut a single sliver at a time, resulting in low production efficiency; and some machines attempting multi-channel synchronous cutting structures suffer from inadequate coordination between feeding and cutting. For instance, the sliver is prone to backtracking or shifting during feeding, leading to inconsistent cutting lengths; the lack of coordination between the cutting mechanism and feeding actions can cause unstable cutting force or blade jamming. Furthermore, existing equipment is often complex in structure, has high maintenance costs, and is difficult to adapt to small-batch production needs. Utility Model Content

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0018] The first aspect of this utility model discloses a cutting machine for PVC pine branches used in Christmas trees, such as... Figure 1-5 As shown, it includes a base 1 and a frame 2 mounted on the base 1. The frame 2 has a movable groove 201 at its axial position, and multiple conveying channels 202 are equidistantly opened inside it along the circumferential axis. The movable rod 3 is slidably installed in the movable slot 201; The electric push rod 4, which is fixed on the base 1, has its output end fixed to the end of the movable rod 3 via a connector 401; Multiple first sliding grooves 5 are equidistantly opened along the circumference at one end of the frame 2. A guide rod 6 is fixed in the first sliding groove 5, and a slider 7 is slidably installed on the guide rod 6. A cutter 8 is fixed on one side of the slider 7, and a push rod 9 perpendicular to the axis of the movable groove 201 is fixed at one end of the cutter 8. The spring 10, which is sleeved on the guide rod 6, has its two ends fixed to the surface of the slider 7 and the inner wall of the first groove 5, respectively. When the electric push rod 4 drives the movable rod 3 to move, the movable rod 3 squeezes the push rod 9 to push the cutter 8 to move towards the loose strip 15 in the conveying channel 202 for cutting.

[0019] During the movement of the movable rod 3, when the conveyed loose sliver 15 is pushed and its section moves to the cutter 8, the end of the movable rod 3 is pressed against multiple push rods 9, causing the push rods 9 to push the corresponding loose sliver 15 of the cutter 8 closer, and the spring 10 is compressed and contracted. After the push rod 9 moves into position, the cutter 8 completes the cutting of the loose sliver 15. Then, the output end of the electric push rod 4 pushes the movable rod 3 to move away from the cutter 8 to reset. At this time, the push rod 9 contacts the compression of the movable rod 3, causing the spring 10 to elastically reset, driving the cutter 8 on the slider 7 to move and reset, which facilitates the next cutting of the loose sliver 15 by the cutter 8. In addition, through the multiple circumferentially distributed conveying channels 202 and the integrated drive structure, the efficient synchronous cutting of multiple loose slivers 15 is realized, which greatly improves the production efficiency.

[0020] In this embodiment, one end of the movable rod 3 is a tapered surface, and one end of the push rod 9 is an arc surface that mates with the tapered surface. It should be noted that by having the tapered surface of one end of the movable rod 3 mate with the arc surface of one end of the push rod 9, the contact area between the movable rod 3 and the push rod 9 is reduced, facilitating the movement of the push rod 9.

[0021] In this embodiment: a plurality of blade holders 11 are fixed at equal intervals along the circumference at one end of the frame 2, and the blade holders 11 cooperate with adjacent cutters 8. The blade holders 11 have grooves inside that cooperate with the ends of the cutters 8. After the push rod 9 pushes the cutter 8 fixed thereto into place, the end of the cutter 8 is inserted into the blade holder 11, restricting the further movement of the cutter 8. When the cutter 8 moves to the groove position of the blade holder 11, the shearing between the vertical surface of the cutter 8 and the groove on the inner wall of the blade holder 11 facilitates the cutting of the loose strip 15.

[0022] In this embodiment, the cutting machine also includes several second slide grooves 13 opened inside the frame 2. The second slide grooves 13 are connected to the adjacent movable grooves 201 and the adjacent conveying channels 202. A pusher 14 is provided through the interior of the second slide grooves 13. One end of the pusher 14 is fixed to the surface of the movable rod 3, and the other end of the pusher 14 extends into the conveying channel 202.

[0023] In the process of conveying and cutting pine branches 15, the output end of the electric push rod 4 first retracts and drives the movable rod 3 to move through the connector 401. Since the pushing part 14 moves in the opposite direction to the natural downward direction of the leaf needles on the pine branch 15, and the pushing part 14 is located in the "bare rod" area of ​​the leaf needles of the pine branch 15, the pushing part 14 on the movable rod 3 pushes the reverse leaf needles as it moves. Under the push of the leaf needles of the pine branch 15, the pine branch 15 is moved closer to the cutter 8. After the pushing part 14 pushes the pine branch 15 to the limit position, it is pushed to the position of the cutter 8 in the "bare rod" area of ​​the pine branch 15. At the same time, the conical surface at the end of the movable rod 3 squeezes the push rod 9 at the end of the corresponding cutter 8, so that the push rod 9 pushes the cutter 8 to move towards the pine branch 15 and cuts the pine branch 15, thus realizing the automatic completion of conveying and cutting multiple pine branches 15.

[0024] In this embodiment, the pusher 14 includes a pusher end and a connecting rod. One end of the connecting rod is fixed to the pusher end, and the other end is fixed to the surface of the movable rod 3. The pusher end is located inside the conveying channel 202. It should be noted that, since the pusher end on the pusher 14 is located in the conveying channel 202, as the movable rod 3 moves toward the cutter 8, the pusher end can act on the blade needles of the loose slats 15, thereby pushing the loose slats 15 to move toward the cutter 8.

[0025] In this embodiment, the pusher end has a groove on one side of the conveying channel 202. By setting the groove on the pusher end, when the pusher end contacts the loose bar 15, the groove portion can increase the contact area between the groove portion and the "smooth bar" area of ​​the loose bar 15, which facilitates the pushing of the loose bar 15.

[0026] In this embodiment, at least one side of the inner wall of the conveying channel 202 is provided with an inclined groove 2021 along the direction in which the blade needles of the pine stalk 15 naturally hang downwards. It should be added that the inner wall of the conveying channel 202 can have multiple sets of inclined grooves 2021 equidistantly spaced along the circumference. By coordinating the inclined grooves 2021 on the inner wall of the conveying channel 202 with the inclination angle of the blade needles of the pine stalk 15, after the pusher 14 pushes the blade needles of the pine stalk 15 into place, when the movable rod 3 drives the pusher 14 to reset, the blade needles of the pine stalk 15 will be stuck in the inclined groove 2021 as the pusher 14 moves back. This restricts the tendency of the pusher 14 to pull the pine stalk 15 backwards, thereby preventing the pine stalk 15 from moving back after being pushed, ensuring stable conveying of the pine stalk 15, facilitating subsequent cutting operations of the pine stalk 15, improving cutting accuracy, and adapting to the production needs of small batch products.

[0027] In this embodiment, a collection box 12 is provided below one end of the frame 2, and the collection box 12 is located below the cutter 8. After the loose strands 15 are cut, the loose strands 15 fall into the collection box 12 for collection.
