Description

Technical Field

[0001] This utility model relates to the field of bottle preform production and processing technology, and more specifically, to a bottle preform arranging mechanism with equal spacing. Background Technology

[0002] Preforms are formed by filling the mold with raw materials under specific temperature and pressure during injection molding. They are semi-finished products that are formed through injection molding. In automated production workshops, preforms are usually arranged on production conveyor lines for transportation.

[0003] When the preforms move to the rear end of the conveyor line, the robot will pick them up from the conveyor line and transfer them to the next workstation. However, the preforms on the conveyor line are usually arranged closely, making it difficult for the robot to pick up the preforms arranged closely on the production line individually. Collisions or multiple gripping may occur during the gripping process, making it inconvenient to automatically remove the preforms from the conveyor line by the robot. Utility Model Content

[0004] This invention provides a preform arrangement mechanism with equal spacing, which solves the technical problem in the prior art that it is difficult for a robot to individually grip tightly arranged preforms on the production line, and it is not convenient to automatically remove preforms from the conveyor line by a robot.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A preform arranging mechanism with equal spacing includes a support, a sloping groove at the top of the support, the rear side of the sloping groove being inclined downward relative to the front side, a horizontally arranged push cylinder mounted on one side of the support, one end of the output shaft of the push cylinder extending into the interior of the support and fixedly connected to one side of the sloping groove, a fixing plate at the top of the sloping groove, and a first preform clamp and a second preform clamp respectively provided on one side of the fixing plate.

[0007] Furthermore, ball bearings are rotatably connected to both sides of the inner wall of the first preform slot and the second preform slot on the fixing plate, and the ball bearings are distributed in two rows at the top and bottom of the fixing plate.

[0008] Furthermore, a slide rail is fixedly installed on the bracket, and a slider is fixedly connected to the bottom end of the fixing plate, with the slide rail slidably connected to the slider.

[0009] Furthermore, a bolt is fixedly connected to the top of the inclined groove, and mounting holes corresponding to the bolt are provided on the fixing plate.

[0010] Furthermore, the lane arrangement mechanism also includes a set of bases, on both sides of which are fixedly installed vertically arranged electric telescopic rods, one end of the output shaft of the electric telescopic rods being connected to the bottom of the inclined groove.

[0011] Furthermore, screw holes are provided around the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the mechanism at the rear end of the preform conveying line, when the push cylinder is started, the output shaft of the push cylinder can control the inclined chute and the fixed plate to move horizontally by moving back and forth. When the first preform clamp and the second preform clamp on one side of the fixed plate are aligned with the preforms on the conveying line in sequence, the preforms can be moved to the front side of the inclined chute by the drive of the conveying line. The preforms will slide to the rear side of the inclined chute and finally be embedded in the first preform clamp and the second preform clamp. At this time, the two sets of preforms embedded in the first preform clamp and the second preform clamp will separate from each other and maintain a fixed distance, which makes it easier for the robot arm in the later process to pick up the preforms on the inclined chute.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 A preform sorting mechanism with equal spacing includes a support 1. A sloping groove 2 is provided at the top of the support 1. When the support 1 is positioned at the rear end of the preform conveying line, the front side of the sloping groove 2 is flush with the height of the conveying line, and the rear side of the sloping groove 2 is slightly inclined downwards relative to the front side. When a preform on the conveying line moves to the front side of the sloping groove 2, the preform slides from the front side to the rear side. A horizontally positioned push cylinder 3 is installed on one side of the support 1. One end of the output shaft of the push cylinder 3 extends into the interior of the support 1 and is fixedly connected to one side of the sloping groove 2. The output shaft of the sloping groove 2 can drive the sloping groove 2 through horizontal telescopic movement. The inclined chute 2 is moved horizontally back and forth. A fixing plate 4 is provided at the top of the inclined chute 2. A first preform clamp 5 and a second preform clamp 6 are respectively provided on one side of the fixing plate 4. When the bracket 1 is set at the end of the preform conveying line, the openings of the first preform clamp 5 and the second preform clamp 6 will face the preforms on the preform conveying line. The width of the first preform clamp 5 and the second preform clamp 6 is slightly larger than the diameter of the preforms on the preform conveying line. Therefore, when the first preform clamp 5 or the second preform clamp 6 is aligned with the preforms on the conveying line, the preforms that move onto the inclined chute 2 will always be embedded inside the first preform clamp 5 and the second preform clamp 6.

[0022] During use, this mechanism is installed at the rear end of the preform conveying line. When the push cylinder 3 is activated, the output shaft of the push cylinder 3 can control the inclined chute 2 to move horizontally by extending and retracting back and forth. The fixed plate 4 at the top of the inclined chute 2 will also move horizontally. When the first preform clamp 5 on one side of the fixed plate 4 is aligned with the preform on the conveying line, the preform can be moved to the front of the inclined chute 2 by the drive of the conveying line. The preform will then slide towards the rear of the inclined chute 2 and finally be embedded in the first preform clamp 5. Then, the second preform clamp 6 on one side of the fixed plate 4 is aligned with the preform on the conveying line. The preform can be moved to the front of the inclined chute 2 by the drive of the conveying line. The preform will then slide towards the rear of the inclined chute 2 and finally be embedded in the second preform clamp 6. At this time, the two sets of preforms embedded in the first preform clamp 5 and the second preform clamp 6 will separate from each other and maintain a fixed distance, which makes it easier for the robot arm in the later process to pick up the preforms on the inclined chute 2. Both sets of preforms can be picked up at a time, which makes the picking efficiency high.

[0023] For further details, please refer to Figure 1-4 On the fixing plate 4, ball bearings 7 are rotatably connected to the inner walls of the first preform slot 5 and the second preform slot 6. The ball bearings 7 are arranged in two rows at the top and bottom of the fixing plate 4. When the preform moves into the first preform slot 5 or the second preform slot 6, the two sides of the preform will roll into contact with the ball bearings 7. The ball bearings 7 can prevent the side walls of the first preform slot 5 or the second preform slot 6 from contacting and rubbing with the preform, thereby avoiding scratches on the sides of the preform.

[0024] For further details, please refer to Figure 1-4 A slide rail 8 is fixedly installed on the bracket 1, and a slider 9 is fixedly connected to the bottom end of the fixed plate 4. The slide rail 8 is slidably connected to the slider 9. When the fixed plate 4 moves under the driving action of the push cylinder 3, the slider 9 will always slide along the direction of the slide rail 8 under the drive of the fixed plate 4. At this time, the slide rail 8 and the slider 9 will guide the movement of the fixed plate 4, so that the fixed plate 4 can always maintain a horizontal straight movement trajectory without deviating.

[0025] For further details, please refer to Figure 1-4 The top end of the inclined groove 2 is fixedly connected with a bolt 10. The fixing plate 4 has mounting holes 11 corresponding to the bolt 10. After aligning the mounting holes 11 on the fixing plate 4 with the bolt 10 at the top end of the inclined groove 2, the top end of the bolt 10 can be inserted into the mounting holes 11. At this time, the nut can be rotated and tightened onto the bolt 10 to fix the fixing plate 4 at the top end of the inclined groove 2. Therefore, the fixing plate 4 at the top end of the inclined groove 2 can be easily disassembled and assembled, making it easy to replace the fixing plate 4. This allows the first preform clamp 5 and the second preform clamp 6 on the fixing plate 4 to adapt to preforms of different diameters.

[0026] For further details, please refer to Figure 1-4 The lane arrangement mechanism also includes a set of bases 12, which are flat structures. Vertically arranged electric telescopic rods 13 are fixedly installed on both sides of the bases 12. One end of the output shaft of the electric telescopic rod 13 is connected to the bottom of the inclined chute 2. The lane arrangement mechanism can be supported at the end of the conveyor line by the bases 12. The electric telescopic rods 13 are connected to a set of control switches. When the electric telescopic rods 13 are started, they can push the bracket 1 to move up and down, thereby adjusting the height of the inclined chute 2. Therefore, the height of the inclined chute 2 can adapt to conveyor lines of different heights. The bases 12 are provided with screw holes 14 around their perimeter. When expansion screws are passed through the screw holes 14 and driven into the ground, the bases 12 can be fixed to the ground, thereby keeping the overall position of the lane arrangement mechanism fixed and preventing displacement under external force.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
