Description

Technical Field

[0001] The utility model relates to the field of Christmas tree processing, in particular to a Christmas tree flocking device. Background Art

[0002] As a decoration for Christmas, Christmas trees are widely used. Christmas trees are the most commonly used artificial tree-shaped decorations in Christmas celebrations. Spraying flocking on Christmas trees can create a snowflake effect, which can better enhance the festive atmosphere. At present, most Christmas tree flocking is carried out manually, that is, workers hold a flocking gun and rotate the Christmas tree while performing the flocking operation, and repeat this process to flock the entire tree until completion. Such flocking has low efficiency, poor flocking uniformity and stability, resulting in uneven "snowflake" effects on the Christmas trees after flocking, affecting the sensory experience. At the same time, long-term work in such an environment has a certain adverse impact on health.

[0003] Therefore, an automated device for flocking Christmas trees is disclosed in the prior art, which includes a linkage-controlled flocking device and a Christmas tree rotating device; the linkage-controlled flocking device is composed of a left-right translation console, an up-down translation console and a flocking component; the left-right translation console slidably supports the up-down translation console for left-right translation of the up-down translation console; the up-down translation console slidably supports the flocking component for up-down translation of the flocking component; the flocking component performs equidistant flocking on the Christmas tree on the Christmas tree rotating device; it can evenly and stably flock the flocking material onto the Christmas tree, achieving the effect that the flocking amount per unit area is basically equal. However, the existing rotating device installs the tree trunk through a sleeve with an inner diameter slightly larger than the tree trunk, and the tree trunk is fixed to the sleeve through structures such as pins and clamping grooves, so that the sleeve can drive the tree trunk to rotate. The method of fixing the tree trunk with pins requires workers to lock or unlock each Christmas tree, which is relatively cumbersome, and this fixing method will cause the Christmas tree to contact the sleeve and the pin respectively, thus deviating from the central axis of the sleeve. Especially when fixing and rotating and flocking other specifications and smaller-diameter Christmas trees, the rotation axis of the Christmas tree deviates far from the central axis of the sleeve. And the rotation axis of the existing rotating device usually coincides with the central axis of the sleeve. Therefore, the existing fixing method cannot make the axis direction of the Christmas tree coincide with the rotation axis, resulting in the Christmas tree swinging during the rotating processing and uneven flocking. At the same time, since the flocking component plans the spraying path according to the rotation axis of the rotating device or the Christmas tree in a static state, the position of the Christmas tree shifts during the rotation process, which will cause the area with a narrower top of the Christmas tree to actually not be flocked, the "snowflake" effect is poor, and the realism decreases. Therefore, it is necessary to improve the fixing structure, strengthen the fixing of the Christmas tree trunk, improve the flocking effect of the Christmas tree, and improve the convenience of the fixing structure, so that the fixing structure can quickly and conveniently fix the Christmas tree and improve work efficiency. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a flocking device for Christmas trees to improve the flocking effect of Christmas trees.

[0005] The present utility model is realized through the following technical solutions: A flocking device for Christmas trees, comprising:

[0006] A conveying mechanism, including a conveying track and a conveying bottom plate. A first working station is provided on the conveying track, and a plurality of the conveying bottom plates are arranged and move along the conveying track;

[0007] A rotating mechanism, including a positioning component, a driving motor, and a locking component. The driving motor is fixedly arranged on the conveying bottom plate. The positioning component is provided with a first chamber for accommodating the trunk of the Christmas tree. The bottom of the positioning component is fixedly connected to the output shaft of the driving motor. The locking component is arranged on the top or inside of the positioning component for locking the Christmas tree, and the driving motor is used to drive the Christmas tree to rotate;

[0008] A fixing mechanism for fixing the conveying bottom plate at the first working station;

[0009] A flocking mechanism for flocking the Christmas tree at the first working station.

[0010] Compared with the prior art, the flocking device provided by the present utility model uses the locking component to fix the Christmas tree at the center of the sleeve, making the rotation axis of the Christmas tree coincide with the rotation axis of the rotating mechanism, improving the flocking effect of the Christmas tree and reducing the waste of flocking raw materials.

[0011] Furthermore, the positioning component includes a sleeve with an inner diameter slightly larger than the trunk of the Christmas tree. A frustum-shaped limiting structure matching the shape of the bottom of the trunk of the Christmas tree is provided at the bottom of the sleeve. Through this limitation, the Christmas tree can quickly coincide with the rotation axis of the rotating mechanism under the action of the limiting structure and the locking component.

[0012] Furthermore, a plurality of ribs are arranged at intervals along the circumferential direction of the top of the sleeve. The locking component includes an adjusting part and a locking part. The adjusting part is an annular shape with an opening. Limiting blocks protruding from the adjusting part are provided at both ends of the adjusting part. The locking part is arranged between the two limiting blocks for adjusting the distance between the two limiting blocks. By setting the annular adjusting part to lock the plurality of ribs above the sleeve, the centers of the plurality of ribs coincide with the rotation axis of the sleeve.

[0013] Further, the locking member includes an outer tube and an inner tube. One end of the inner tube is slidably disposed inside the outer tube, and one end protrudes from the outer tube and is fixedly connected to one of the limiting blocks of the adjusting member. The inner part of the outer tube has a plurality of card slots arranged along the length direction of the outer tube. The inner tube is provided with a clamping portion that is clamped in the card slots. The end of the outer tube away from the inner tube is fixedly connected to the other limiting block of the adjusting member. Through this limitation, the trunks of Christmas trees of different specifications can be locked.

[0014] Further, a groove is formed on the side of the limiting block connected to the inner tube away from the inner tube; an active limiting block and an active rod are arranged inside the inner tube. The active limiting block is slidably disposed at the bottom of the inner tube. The active limiting block is provided with a clamping portion, and the clamping portion passes through the inner tube and is clamped with the card slot. The side of the active limiting block facing away from the clamping portion is connected to the inner tube through a spring. The active limiting block is further provided with an inclined chute. One end of the active rod is slidably disposed in the groove, and the other end passes through the limiting block and is slidably connected to the chute. When the active rod slides along the groove and the chute, the projection of the clamping portion and the card slot in the plane where the card slot is located can be switched between at least partial overlap and complete non - overlap. By pressing the locking member to cooperate the spring limiting structure of the locking member with different card slots of the fixed tube, the inner diameter of the adjusting member is adjusted, and thus the inner diameters of multiple ribs are adjusted to achieve quick locking or unlocking of Christmas trees of different specifications.

[0015] Further, the positioning assembly further includes a second chamber for installing the locking assembly. The second chamber is disposed below the sleeve, and two opposite openings are formed on the side of the chamber; the locking assembly includes two connecting rods, a telescopic rod, two connecting portions and two fixing portions. The telescopic rod is disposed inside the chamber. The two connecting rods are symmetrically arranged on both sides of the sleeve, and the middle of the connecting rod is pivotally connected to the outer wall of the sleeve. One end of the connecting rod passes through the opening and is pivotally connected to one end of the telescopic rod, and the other end is pivotally connected to the end of a connecting portion through a movable rod. The other end of the connecting portion passes through the sleeve and is fixedly connected to a fixing portion. The telescopic movement of the telescopic rod pushes the two connecting rods to rotate around their connection with the sleeve, and further pushes the fixing portions to move towards or away from each other to achieve locking or unlocking of the Christmas tree.

[0016] Further, the fixing portion is of an arc structure, and the inner side is made of a flexible material. Through this setting, the Christmas tree can be better fixed and driven to rotate.

[0017] Further, the telescopic rod is a hydraulic rod and is electrically connected to the control system. The control system can lock or unlock the Christmas tree according to the position signal of the conveying bottom plate or the opening and closing signal of the rotating structure, so as to facilitate the workers to quickly install the Christmas tree onto the positioning mechanism without manual locking and unlocking.

[0018] Further, a protrusion is provided between the connection positions of the connecting rod with the sleeve and the telescopic rod; the positioning assembly further includes a sliding member disposed at the communication position between the sleeve and the chamber, which is slidable between its first position and second position. At the first position, at least a part of the projection of the sliding member on the horizontal plane overlaps with the limiting structure. The bottom of the sliding member is located in the chamber and two limiting blocks are symmetrically arranged. The two limiting blocks are respectively pivotally connected to the protrusions of the two connecting rods through a movable part, so that the sliding of the sliding member drives the two fixing parts to move towards or away from each other. By providing a locking assembly and a sliding member that cooperate with each other, when the Christmas tree is installed on the sleeve, the Christmas tree pushes the sliding member downward, driving the locking assembly to quickly lock the Christmas tree.

[0019] Further, the top of the sliding member is connected to the bottom of the sleeve through a return spring. With this setting, when the Christmas tree is taken out, the sliding member can automatically reset, and the inner diameter of the fixing part becomes the largest, facilitating the installation of the next Christmas tree.

[0020] Further, the fixing mechanism includes a limiting member, a limiting driving cylinder, a fixing block and a fixing driving cylinder. The limiting member is arranged in front of the first station to limit the conveying bottom plate at the first station, and the limiting driving cylinder drives the limiting member to release the conveying bottom plate; the fixing driving cylinder pushes the fixing block to abut against the conveying bottom plate at the first station to prevent the conveying bottom plate from colliding with the conveying track. The conveying bottom plate is fixed from two directions, reducing the position deviation of each conveying bottom plate at the first station, making the rotation axes of the sleeves on each conveying bottom plate consistent, and facilitating the operation of the fluff spraying mechanism.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Please refer to Figure 1, an embodiment of the present application provides a Christmas tree fluffing device, which includes a conveying mechanism 10, a rotating mechanism 20, a fixing mechanism 30, and a fluffing mechanism 40. The conveying mechanism 10 includes a conveying track 11 and a conveying bottom plate 12. A first station is provided on the conveying track 11. The conveying bottom plate 12 is provided as at least one and moves along the conveying track 11 for conveying Christmas trees. The fixing mechanism 30 fixes the conveying bottom plate 12 at the first station. The rotating mechanism 20 drives the Christmas tree to rotate. The fluffing mechanism 40 is used for fluffing the Christmas tree at the first station.

[0037] Please refer to Figure 1-2 , further, in some embodiments, the rotating mechanism 20 includes a positioning component 21, a driving component 22, and a locking component 23. The positioning component 21 is arranged on the conveying bottom plate 12 for positioning and installing the Christmas tree. The driving component 22 is used for driving the Christmas tree to rotate. The locking component 23 is arranged on the top and / or inside of the positioning component 21 for locking the Christmas tree so that the rotation axis of the Christmas tree coincides with the central axis of the positioning component 21.

[0038] Further, a groove is formed in the middle of the conveying bottom plate 12, or a fixing seat is arranged in the middle of the conveying bottom plate 12. The driving component 22 is fixedly arranged in the groove or the fixing seat. The positioning component 21 is fixedly connected to the driving component 22. Specifically, the driving component 22 includes a driving motor 221, and the driving motor 221 is fixedly arranged in the groove or the fixing seat of the conveying bottom plate 12. The positioning component 21 includes a sleeve 211 with an inner diameter slightly larger than the trunk of the Christmas tree. The sleeve 211 has a first chamber for accommodating the trunk of the Christmas tree. The bottom of the sleeve 211 is fixedly connected to the output shaft of the driving motor 221, and the rotation axis of the rotating mechanism 20 coincides with the central axis of the sleeve 211. Preferably, a baffle extends outward from the bottom of the sleeve 211, and the edge of the baffle bends downward to prevent fluffing waste from entering the driving motor 221 and affecting the normal operation of the driving motor 221.

[0039] Please refer to Figure 2-6, Further, in some embodiments, a plurality of ribs 212 are provided at the top of the sleeve 211. The plurality of ribs 212 are spaced along the circumferential direction of the sleeve 211, and a limiting portion protruding outward is provided at the top of the plurality of ribs 212. The locking assembly 23 includes an adjusting member 231 and a locking member 232. The adjusting member 231 is sleeved outside the plurality of ribs 212 and is located below the limiting portion to prevent the adjusting member 231 from detaching from the plurality of ribs 212. The adjusting member 231 is a circular ring structure with an opening. Limiting blocks protruding from the adjusting member 231 are provided on both sides of the opening of the adjusting member 231. The locking member 232 is disposed between the two limiting blocks to lock the adjusting member 231, so that the plurality of ribs 212 contract to fix the Christmas tree.

[0040] In some embodiments, positioning holes are provided at positions corresponding to the two limiting blocks. The locking member 232 passes through the positioning holes of the two limiting blocks to fix the adjusting member 231, thereby fixing the Christmas tree, enabling the sleeve 211 to drive the Christmas tree to rotate, and preventing the Christmas tree from swinging during the rotary flocking process, which may cause uneven spraying of the fluff. Preferably, the Christmas tree fluff spraying device is applicable to Christmas trees of different specifications. The outer diameters of the trunks of Christmas trees of different specifications are different. The inner diameter of the sleeve 211 is slightly larger than the outer diameter of the trunk of the largest specification of the Christmas tree. The inner diameter of the adjusting member 231 in its natural state is slightly smaller than the outer diameter of the sleeve 211. The locking member 232 adjusts the inner diameter of the adjusting member 231 by adjusting the distance between the two limiting blocks, thereby adjusting the inner diameter of the ring formed by the plurality of ribs 212, so that the positioning assembly 21 is applicable to Christmas trees of different specifications. By providing a plurality of ribs 212 and the adjusting member 231 as a circular ring, the rotation axis of the Christmas tree coincides with the rotation axis of the rotation mechanism 20, so that the rotation axis of the Christmas tree, the rotation axis of the rotation mechanism 20, and the movement track of the fluff spraying mechanism 40 are parallel and located in the same horizontal plane, thereby improving the uniformity of fluff spraying and reducing the waste of raw materials.

[0041] In other embodiments, both ends of the locking member 232 are fixedly connected to the limiting blocks on both sides of the adjusting member 231. The locking member 232 includes an outer tube 2321 and an inner tube 2322. One end of the inner tube 2322 is slidably disposed inside the outer tube 2321, and one end protrudes from the outer tube 2321 and is fixedly connected to one of the limiting blocks of the adjusting member 231. The end of the outer tube 2321 away from the inner tube 2322 is fixedly connected to the other limiting block of the adjusting member 231. One of the inner tube 2322 and the outer tube 2321 is provided with a plurality of card slots, and the other is provided with a limiting post that cooperates with the card slots. By engaging the limiting post with one of the plurality of card slots, the length of the locking member 232 is adjusted, thereby locking or unlocking Christmas trees of different specifications.

[0042] Specifically, a spring limiting structure is provided inside the inner tube 2322. The spring limiting structure includes a movable rod 2323, a movable limiting block 2324, and a fixed block 2325. The fixed block 2325 is hollow inside and is fixedly connected to the end of the inner tube 2322 located inside the outer tube 2321 at the outside, and the fixed block 2325 is provided with a hole corresponding to the position of the card slot. The movable limiting block 2324 is slidably disposed inside the fixed block 2325. A limiting post is provided on the first side surface of the movable limiting block 2323. The limiting post passes through the hole of the fixed block 2325 and is clamped with the card slot. The second side surface of the movable limiting block 2324 away from the limiting post is fixedly connected to the inner wall of the fixed block 2324 through a spring. When the spring extends, the limiting post of the movable limiting block 2324 protrudes from the fixed block 2325 and is clamped with one of the card slots of the fixed tube 2321, realizing the locking of the spring limiting structure and the fixed tube 2321. When the spring is compressed, the limiting post contracts from the card slot into the hole of the fixed block 2325, so that the spring limiting structure can slide in the fixed tube 2321.

[0043] Further, an inclined downward chute is provided on one side surface of the movable limiting block 2324. The top end of the chute is close to the second side surface, and the bottom end is close to the first side surface. One end of the movable rod 2323 is slidably connected to the limiting block of the adjusting member 231 away from the outer tube 2321, and the other end is clamped with the chute of the movable limiting block 2324 and can slide along the chute. Specifically, a groove for the movable rod 2323 to slide is provided on the side of the limiting block connected to the movable rod 2323 away from the outer tube 2321. The groove and the fixed block 2325 are provided with through holes corresponding to the positions. The end of the movable rod 2323 passes through the groove and the through hole of the fixed block and is clamped with the chute of the movable limiting block 2324. The other end of the movable rod 2323 is disposed in the groove and can slide along the groove. When the movable rod slides along the groove and the chute, the projection of the clamping portion and the card slot on the plane where the card slot is located can be converted between at least partial overlap and complete non-overlap. In the natural state, one end of the movable rod 2323 is located at the top of the groove, and the other end is clamped at the top end of the chute. When the spring extends, the movable limiting block 2324 is pushed towards the card slot of the fixed tube 2325, so that the limiting post of the movable limiting block 2324 passes through the hole of the fixed block 2325 and is clamped with one of the card slots of the fixed tube 2324. When the movable rod 2323 is pressed, the movable rod 2323 slides from the top of the groove at one end to the bottom of the groove, and the other end slides from the top end of the chute to the bottom end of the chute. The movable limiting block 2324 moves towards the spring direction to compress the spring, so that the limiting post contracts inwards into the hole of the fixed block 2325. At this time, pulling the movable rod 2323 can adjust the overall length of the locking member 232, thereby adjusting the inner diameter of the adjusting member 231 to lock or unlock Christmas trees of different specifications.

[0044] In some embodiments, the movable rod 2323 is located at the end of the groove and is connected to the bottom of the groove by a spring, so that the movable rod 2323 can automatically reset, and the Christmas tree can be locked more conveniently.

[0045] Refer to Figure 7-10 Furthermore, in some embodiments, the sleeve 211 further includes a second chamber located below the first chamber, and the second chamber is used to install the locking assembly 23. Specifically, a plurality of through holes 213 are formed in the first chamber of the sleeve 211, and openings 214 corresponding in position are formed on opposite sides of the second chamber. The locking assembly 23 includes a first connecting rod 233, a second connecting rod 234 and a telescopic rod 235. The telescopic rod 235 is disposed in the second chamber, and two ends of the telescopic rod 235 are respectively pivotally connected to ends of the first connecting rod 233 and the second connecting rod 234. The other ends of the first connecting rod 233 and the second connecting rod 234 respectively extend out of the second chamber from an opening 214. A first connecting portion 233a and a first fixing portion 233b are disposed at an end of the first connecting rod 233 away from the telescopic rod 235. The first fixing portion 233b is disposed inside the sleeve 211. One end of the first connecting portion 233a is fixedly connected to the first fixing portion 233b, and the other end passes through the through hole 213 of the sleeve 211 and is pivotally connected to the first connecting rod 233 through a movable rod. A second connecting portion 234a and a second fixing portion 234b are disposed at an end of the second connecting rod 234 away from the telescopic rod 235. The second fixing portion 234b is disposed inside the sleeve 211. One end of the second connecting portion 234a is fixedly connected to the second fixing portion 234b, and the other end passes through the through hole 213 of the sleeve 211 and is pivotally connected to an end of the second connecting rod 234 away from the telescopic rod 235 through a movable rod. The first fixing portion 233b and the second fixing portion 234b are disposed opposite to each other. The outer side of the sleeve 211 is fixedly connected to the first connecting rod 233 and the second connecting rod 234 respectively, and the connection positions are between the first connecting portion 233a or the second connecting portion 234a and the opening 214. Preferably, the first fixing portion 233b and the second fixing portion 234b are arc-shaped structures. When the telescopic rod 235 expands and contracts, the telescopic rod 235 pushes the first connecting rod 233 and the second connecting rod 234 to rotate around their connection positions with the sleeve 211, so that the first fixing portion 233b and the second fixing portion 234b move towards or away from each other, realizing clamping or loosening of the Christmas tree.

[0046] Further, the telescopic rod 235 includes an outer rod 235a and an inner rod 235b. The outer rod 235a is slidably connected to the inner rod 235b. One end of the inner rod 235b can slide in the outer rod 235a, and the other end is pivotally connected to the first link 233. The end of the outer rod 235a away from the inner rod 235b is pivotally connected to the second link 234. Preferably, a limiting block is provided on the outer rod 235a or the inner rod 235b to prevent the inner rod 235b from falling off the outer rod 235a.

[0047] In some embodiments, the telescopic rod 235 is a hydraulic structure, and can control the first link and the second link to rotate around their connection points with the sleeve 211 according to the instructions of the control system, so as to lock or unlock the Christmas tree. Further, the control system can lock or unlock the telescopic rod 235 according to the position of the conveying bottom plate 12 and / or the opening and closing of the rotating mechanism 20, so that the Christmas tree is locked before fluff spraying and unlocked after the fluff spraying is completed.

[0048] Refer to Figure 9-10 Furthermore, in some embodiments, the rotating mechanism 20 further includes a sliding member 24. The sliding member 24 is slidably disposed in the middle of the sleeve 211, at the communication of the first chamber and the second chamber. The top of the sliding member 24 is located in the first chamber and forms a limiting portion to prevent the sliding member 24 from falling off the sleeve. The bottom of the sliding member 24 is located in the second chamber, and a first limiting block 241 and a second limiting block 242 are symmetrically disposed at the bottom. The first limiting block 241 is connected to the first link 233 through a first movable portion, and the second limiting block 242 is pivotally connected to the second link 234 through a second movable portion. The sliding member 24 can slide between its first position and second position. When located at the first position, the limiting portion of the sliding member 24 abuts against the bottom of the first chamber. When located at the second position, the first limiting block 241 and the second limiting block 242 of the sliding member 24 abut against the top of the second chamber. Further, the limiting portion of the sliding member 24 is connected to the bottom of the first chamber through a return spring, and / or the first limiting block 241 and the second limiting block 242 of the sliding member 24 are connected to the top of the second chamber through a return spring. When the sliding member 24 is not pressed by the Christmas tree, the return spring resets the sliding member 24 to its second position.

[0049] Specifically, a first protrusion 233c is fixedly provided in the middle of the first connecting rod. One end of the first protrusion 233c is pivotally connected to one end of the first movable part, and the other end of the first movable part is pivotally connected to the first limiting block 241. A second protrusion 234c is fixedly provided in the middle of the second connecting rod. One end of the second protrusion 234c is pivotally connected to one end of the second movable part, and the other end of the second movable part is pivotally connected to the second limiting block 242. In this embodiment, the protrusion and the movable part are rod-shaped. The first protrusion 233c is located below the connection between the first connecting rod 233 and the sleeve 211, and the second protrusion 234c is located below the connection between the second connecting rod 234 and the sleeve 211. By providing the sliding member 24, the trunk of the Christmas tree installed in the sleeve can drive the sliding member to slide down, thereby pushing the connecting rod to rotate around the connection between the connecting rod and the sleeve, and making the fixed part of the connecting rod move towards the Christmas tree to clamp the trunk of the Christmas tree.

[0050] Further, in some embodiments, a limiting structure 215 that matches the shape of the bottom of the trunk of the Christmas tree is provided at the bottom of the first chamber. The limiting structure 215 includes an inclined portion that tapers from top to bottom and a vertical portion that extends vertically downward from the inclined portion. The junction of the inclined portion and the vertical portion is located between the first position and the second position of the sliding member 24. In the prior art, the trunk of the Christmas tree is cylindrical, and the bottom of the trunk tapers inward to form a frustum structure with a reduced diameter. By providing the limiting structure 215 that matches the frustum structure of the Christmas tree, the locking assembly 23 and the limiting structure 215 jointly and quickly fix the Christmas tree in the middle of the sleeve 211 to prevent the Christmas tree from tilting.

[0051] Refer to Figure 9 , preferably, the limiting structure 215 matches the shape of the frustum structure of the trunk of the largest-sized Christmas tree. When the sliding member 24 is in the first position, the top of the sliding member 24 slightly protrudes from the vertical surface of the limiting structure 215. The thicknesses of the first fixing part 233b and the second fixing part 234b are slightly less than half of the difference between the outer diameter of the trunk of the largest-sized Christmas tree and the inner diameter of the sleeve, so that the largest-sized Christmas tree can be easily placed into the sleeve. Then, the frustum structure of the trunk of the Christmas tree is in full contact with the limiting structure 215, and the bottom contacts the sliding member 24 and pushes the sliding member 24 to slide down. The sliding of the sliding member 24 drives the first connecting rod 233 and the second connecting rod 234 to rotate around their connections with the sleeve 211, so that the first fixing part 233b and the second fixing part 234b move towards the trunk of the Christmas tree to clamp the trunk of the Christmas tree. Refer to Figure 10, when replacing the Christmas tree with a smaller specification, the frustum structure at the bottom of the tree trunk at least partially protrudes from the inclined portion, increasing the downward sliding distance of the sliding member 24, driving the first fixing portion 233b and the second fixing portion 234b to move a longer distance towards the Christmas tree, that is, reducing the distance between the first fixing portion 233b and the second fixing portion 234b, so as to realize that the locking assembly 23 can automatically clamp Christmas trees of different specifications. By providing a limiting structure 215 at the bottom of the first chamber of the sleeve 211, which is matched with the frustum structure of the largest specification Christmas tree, when Christmas trees of different specifications are inserted into the sleeve, the sliding distance of the sliding member is different, so that the locking assembly 23 is adapted to Christmas trees of different specifications, avoiding excessive pressure on the larger specification Christmas tree by the locking assembly 23. When an upward force is applied to the Christmas tree and the Christmas tree no longer presses the sliding member 24, the first fixing portion 233b and the second fixing portion 234b automatically move away from the Christmas tree and release the Christmas tree.

[0052] In some embodiments, the telescopic rod 235 further includes an automatic reset spring. The automatic reset spring is arranged inside the outer rod 235a, with one end connected to the end of the outer rod 235a and the other end connected to the end of the inner rod 235b. When the Christmas tree receives an upward force and no longer presses the sliding member 24, the automatic reset spring causes the inner rod 235b to slide into the inner part of the outer rod 235a, and further causes the first fixing portion 233b and the second fixing portion 234b to move away from each other and release the Christmas tree.

[0053] In other embodiments, the locking assembly 23 may include a greater number of connecting rods, and the plurality of connecting rods are symmetrically arranged around the sleeve 211.

[0054] Furthermore, the side of the fixing portion facing the Christmas tree is made of a flexible material, which can better fix the tree trunk of the Christmas tree.

[0055] Refer to Figure 11~12, Further, in some embodiments, the fixing mechanism 30 includes a limiting member 31, a limiting driving cylinder 32, a fixing block 33, and a fixing driving cylinder 34. The limiting member 31 is disposed in front of the first working station. The limiting driving cylinder 32 drives the limiting member 31 to rotate between its first position and second position. When the limiting member 31 is in the first position, it limits the conveying bottom plate 12 at the first working station. When the limiting member 31 rotates to the second position, the conveying bottom plate 12 leaves the first working station along the conveying track 11. The fixing block 33 and the fixing driving cylinder 34 are disposed on the side of the conveying track 11. When the conveying bottom plate 12 is conveyed to the first working station along the conveying track 11, the fixing driving cylinder 34 pushes the fixing block 33 to abut against the conveying bottom plate 12 to prevent the conveying bottom plate 12 from colliding with the conveying track 11. By providing the limiting member 31 and the fixing block 33, the conveying bottom plate 12 is fixed from two directions, reducing the position deviation of each conveying bottom plate 12 at the first working station and making the rotation axes of the sleeves 211 on each conveying bottom plate 12 consistent, facilitating the operation of the fluff spraying mechanism 40.

[0056] Further, the fixing mechanism 30 further includes a cleaning brush fixedly disposed on the conveying track for cleaning the Christmas tree trunk. The orientation of the cleaning brush forms an acute angle with the fluff spraying direction of the fluff spraying mechanism 40, and the orientation of the cleaning brush is biased towards the rotation direction of the Christmas tree.

[0057] Further, the fluff spraying mechanism 40 is used for fluff spraying the Christmas tree at the first working station. The fluff spraying mechanism 40 includes a robotic arm and a flocking assembly. The robotic arm drives the flocking assembly to perform fluff spraying on the Christmas tree at the first working station.

[0058] Further, baffles 13 are respectively disposed on both sides of the conveying track 11 at the first working station. Both side baffles 13 are bent towards the conveying track 11 and form a passage for the sleeve 211 to pass through. The baffle 13 is used to prevent fluff spraying waste from entering the conveying track 11 and affecting the normal operation of the conveying track 11.

[0059] During use, insert the Christmas tree into the sleeve in the loading area. The locking component automatically locks the Christmas tree, or the Christmas tree is locked by pressing the spring limiting structure, so that the rotation axis of the Christmas tree coincides with the rotation axis of the sleeve. The conveying component conveys the Christmas tree in the conveying direction to the first station. The fixing component starts to clamp and fix the conveying bottom plate at the first station. The driving component moves to drive the sleeve to rotate, thereby driving the Christmas tree to rotate. At this time, the flocking component starts to spray glue and cotton wool on the Christmas tree. After the rotary flocking is completed, the fixing component releases the conveying bottom plate. The conveying component sends the Christmas tree to the unloading area, and applies an upward force to the Christmas tree to automatically unlock the Christmas tree, or unlock the Christmas tree by pressing the spring limiting structure, so as to quickly and conveniently fix and remove the Christmas tree.

[0060] Compared with the prior art, the beneficial effects of the technical solution of the present utility model are as follows:

[0061] (1) A locking member and an adjusting member are provided to lock a plurality of ribs above the sleeve. By pressing the locking member, the spring limiting structure of the locking member is matched with different card slots of the fixed tube, and the inner diameter of the adjusting member is adjusted, so as to adjust the inner diameter of the plurality of ribs, and quickly lock or unlock Christmas trees of different specifications.

[0062] (2) By providing a locking component and a sliding member that cooperate with each other, when the Christmas tree is installed on the sleeve, the Christmas tree pushes the sliding member to slide down, driving the locking component to quickly lock the Christmas tree.

[0063] (3) The locking component of the present utility model fixes the Christmas tree at the center of the sleeve, so that the rotation axis of the Christmas tree coincides with the rotation axis of the rotating mechanism, improving the flocking effect of the Christmas tree and reducing the waste of flocking raw materials.

[0064] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and improvements.
