Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a bottle preform anti-bounce conveyor. Background Art

[0002] When a preform conveyor is in operation, it's typically powered by a motor, driving a conveyor belt. Preforms are placed on the conveyor belt and transported forward as the belt moves. The belt features special anti-slip structures or textures to increase friction with the preforms, preventing them from slipping or bouncing. During the conveying process, guide devices ensure that the preforms follow the predetermined path and avoid deviation. Sensors and other equipment monitor the preform's conveying status, such as position and speed, in real time, allowing for timely adjustment of conveying parameters to ensure stable and continuous preform delivery, improving efficiency and accuracy.

[0003] In existing technology, the spacing between some conveyor chains is designed based on standard preform sizes. Larger preforms cannot be placed on the tracks, or if they are, they become crowded, causing them to squeeze against each other, increasing the risk of collision and damage. Smaller preforms can wobble and shift on the tracks. The fixed size and shape of some preform conveyor clamps mean that when encountering smaller or larger preforms, they either fail to clamp securely, easily falling out, or simply cannot fit into the clamps. Therefore, a preform anti-bounce conveyor has been proposed to address these issues. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] The outside of the fixed plate is fixedly connected to a variable-pitch conveyor belt, and the outer wall of the variable-pitch conveyor belt is fixedly connected to a conveyor belt motor;

[0015] As a further description of the above technical solution:

[0016] The surface of the variable-pitch conveyor belt is fixedly connected with a plurality of soft pads, and the plurality of soft pads are in the shape of two layers, the first layer of the surface is sponge, and the second layer in contact with the variable-pitch conveyor belt is rubber;

[0017] As a further description of the above technical solution:

[0018] The pitch-changing slots are shaped as two slots that gradually narrow toward the middle, and the pitch-changing struts are slidably connected to the inner wall of the pitch-changing slots;

[0019] As a further description of the above technical solution:

[0020] The bottle stacking plate is placed right below the middle of the two variable-pitch conveyor belts, and the other end of the rotating column is fixedly connected to the driving end of the variable-pitch motor.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the present invention, preforms are conveyed by clamping them with two variable-pitch conveyor belts, and the conveyor belt can accommodate different maximum diameters of preforms. A variable-pitch motor drives a rotating column to rotate, causing a cam to rotate. Since the variable-pitch support is slidably connected to the variable-pitch groove on the cam surface, the variable-pitch support drives the variable-pitch conveyor belt to move to the sides or to the center according to the shape of the variable-pitch groove, thereby adjusting the distance between the two variable-pitch conveyor belts to accommodate different maximum diameters of bottles. Two layers of soft pads are fixedly connected to the surface of the variable-pitch conveyor belt, the first layer being sponge and the second being rubber. The surface of the sponge is relatively rough, which can provide a certain amount of friction when in contact with the preform. The good elasticity of the rubber layer can make the sponge better fit the preform when subjected to pressure from the preform, thereby playing a cushioning role. Such a structure can convey preforms of different sizes and shapes, and the soft material can better protect the preforms, effectively reducing the problem of bouncing of the preforms during conveyance.

[0023] 2. In the present invention, the servo motor is started to move the stacking platter to the bottom of the variable-pitch conveyor belt. The electronic slider drives the sliding plate to slide, and the sliding plate drives the stacking platter to slide, thereby adjusting the horizontal position of the stacking platter. The servo motor controls the unloading conveyor belt to control the vertical position of the stacking platter, thereby catching the preforms and accurately stacking them into the stacking platter. The preforms are then neatly stacked together and the stacking platter filled with preforms is then conveyed out. The preforms are placed in an orderly manner, which can improve the space utilization of the conveyor belt, reduce the number of conveying times, and thus improve the overall conveying efficiency.

[0033] The inner wall of the cam 3 is slidably connected to a variable pitch support 7, which adjusts the distance between the two variable pitch conveyor belts 18 by sliding inside the variable pitch groove 5. The outer wall of the conveyor bracket 1 is fixedly connected to a variable pitch motor 2 for controlling the rotation of the cam 3. The outer wall of the conveyor bracket 1 is fixedly connected to two telescopic rods 15 for driving the variable pitch conveyor belt 18 to extend and retract. The other ends of the two telescopic rods 15 are fixedly connected to a fixed plate 16 for fixing the variable pitch conveyor belt 18. The outside of the fixed plate 16 is fixedly connected to the variable pitch conveyor belt 18. The outer wall of the variable pitch conveyor belt 18 is fixedly connected to a conveyor belt motor 17 for driving the variable pitch conveyor belt 18 to transport bottle preforms. The surface of the variable pitch conveyor belt 18 is fixedly connected to a plurality of soft pads 19 to reduce damage to the bottle preforms.

[0034] The multiple soft pads 19 are in the shape of two layers. The first layer is sponge, and the second layer in contact with the variable-pitch conveyor belt 18 is rubber. The two soft layers further protect the bottle preforms. The variable-pitch groove 5 is shaped as two grooves that gradually narrow toward the middle. The variable-pitch support 7 is slidably connected to the inner wall of the variable-pitch groove 5 to accurately adjust the distance between the two variable-pitch conveyor belts 18. The bottle stacking tray 20 is placed directly below the center of the two variable-pitch conveyor belts 18 to facilitate catching the conveyed bottle preforms. The other end of the rotating column 6 is fixedly connected to the drive end of the variable-pitch motor 2.

[0035] Reference Figure 1 、 Figure 2 and Figure 5 The unloading assembly includes an unloading conveyor belt 8, which is convenient for transmitting the delivered bottle preforms. The surface of the unloading conveyor belt 8 is fixedly connected to a fixed plate 10, which is convenient for transmitting on the surface of the unloading conveyor belt 8. The inner wall of the fixed plate 10 is slidably connected to an electronic slider 11, which is convenient for driving the sliding plate 13 to slide. The top of the electronic slider 11 is fixedly connected to two connecting rods 12 for connecting the sliding plate 13. The tops of the two connecting rods 12 are fixedly connected to the sliding plate 13.

[0036] To facilitate the horizontal sliding of the code platter, the four corners of the inner wall of the sliding plate 13 are fixedly connected with positioning pins 14 to facilitate the fixing of the code platter. The top of the sliding plate 13 is detachably connected with a code bottle plate 20 for unloading. The inner wall of the code bottle plate 20 is slidably connected to the positioning pins 14, and the inner wall of the code bottle plate 20 is slidably connected to the outer wall of the positioning pins 14.

[0037] Working principle: When it is necessary to transport bottle preforms, the distance between the variable-pitch conveyor belts 18 is adjusted according to the size of the bottle preforms, and the variable-pitch motor 2 is started. The variable-pitch motor 2 drives the rotating column 6 to rotate, and the rotation drives the cam 3 to rotate. Since the variable-pitch support 7 is slidably connected to the variable-pitch groove 5 on the surface of the cam 3, the variable-pitch support 7 will begin to move to both sides or move closer to the middle according to the shape of the variable-pitch groove 5. The movement of the variable-pitch support 7 will move the variable-pitch conveyor belt 18, thereby adjusting the distance between the two variable-pitch conveyor belts 18 to adapt to the maximum diameter of different bottles. Two layers of soft pads 19 are fixedly connected to the surface of the variable-pitch conveyor belt 18. The first layer is sponge and the second layer is rubber. The surface of the sponge is relatively rough, which can provide a certain friction when in contact with the bottle preform. The good elasticity of the rubber layer can make the sponge better fit the bottle preform when it is under pressure from the bottle preform, which can play a buffering role to prevent collision between the bottle preform and conveyor components and damage to the bottle preform.

[0038] The preforms are transported by clamping them between two conveyor belts. When the transported preforms need to be unloaded, the servo motor 9 is started to move the stacking tray to the bottom of the variable-pitch conveyor belt 18. The electronic slider 11 drives the sliding plate 13 to slide, and the sliding plate 13 drives the stacking tray to slide to adjust the horizontal position of the stacking tray. The servo motor 9 controls the unloading conveyor belt 8 to control the vertical position of the stacking tray, so as to catch the preforms and accurately stack them into the stacking tray, so that the preforms are neatly stacked together, and then the stacking tray filled with preforms is transported out.
