Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying equipment, and in particular relates to an adjustable length feeding mechanism. Background Technology

[0002] In the field of material handling equipment technology, the automation and precise feeding capabilities of the feeding mechanism are key industry concerns. Existing feeding mechanisms often face challenges in adjusting the feeding length when dealing with the material requirements of products of different specifications, making it difficult to quickly adapt to diverse production scenarios and hindering the improvement of production efficiency.

[0003] Currently, most common feeding mechanisms employ a fixed structure design, with a relatively simple control method for the rotation of the active feeding wheel. This lack of a flexible adjustment mechanism makes it difficult to precisely control the feeding length according to actual needs. When dealing with products of different specifications, frequent equipment changes or complex adjustments are required. The inability to easily adjust the feeding length makes it difficult to meet the material requirements of different product specifications. Furthermore, the inflexible rotation control of the active feeding wheel during the feeding process prevents precise intermittent feeding, resulting in insufficient accuracy in feeding length control and impacting production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable length feeding mechanism, which aims to solve the problems existing in the background art.

[0005] This invention is implemented as follows: an adjustable-length feeding mechanism, the core structure of which includes a material rack on which a material roll is rotatably mounted. Material is drawn from the material roll and passes through the gap between the active feeding wheel and the driven pressing wheel. The active feeding wheel and the driven pressing wheel cooperate with each other, using friction to convey the material.

[0006] The power source is an electric motor, whose output is connected to the turntable via a belt, causing the turntable to rotate continuously. A slider assembly is mounted on the turntable, with a slider pin sliding inside. The slider pin rotates and connects to a connecting rod, one end of which is fitted with a spherical bearing. When the turntable rotates, the slider pin reciprocates within the slider assembly, pushing the connecting block through the connecting rod and the spherical bearing.

[0007] The connecting block is mounted on the oscillating gear, which is rotatably positioned on one side of the drive feeding wheel. The drive feeding wheel is equipped with a combined gear, which is connected to the drive feeding wheel via a one-way bearing. The combined gear meshes with the oscillating gear.

[0008] The key structure for adjustable length: The connecting rod is designed as an adjustable rod. By adjusting its length, the rotation angle of the oscillating gear can be changed, thereby controlling the intermittent rotation amplitude of the active feeding wheel and achieving precise adjustment of the feeding length.

[0009] The adjustable-length feeding mechanism provided by this utility model has the following beneficial effects:

[0010] The adjustable-length feeding mechanism provided by this utility model uses a motor to drive a turntable to rotate. This rotation, via a slider assembly, slider pin, connecting rod, and spherical bearing, pushes a connecting block to cause a swing gear to oscillate reciprocally. The motion is then transmitted to a drive feeding wheel with a combination gear through gear meshing. A one-way bearing enables the drive feeding wheel to rotate intermittently in one direction, thus intermittently feeding the material belt. Adjusting the length of the connecting rod changes the rotation angle of the swing gear, thereby achieving different feeding lengths. This allows for precise fulfillment of the material requirements of products with different specifications, improving the adaptability and feeding accuracy of the feeding mechanism.

[0013] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] like Figure 1 As shown in this embodiment of the present invention, an adjustable-length feeding mechanism includes a material rack 1, on which a material roll 2 is rotatably mounted. The adjustable-length feeding mechanism includes:

[0016] The active feeding wheel 4 and the driven pressing wheel 3 cooperate with each other, and the material on the material roll 2 passes between the active feeding wheel 4 and the driven pressing wheel 3;

[0017] An intermittent feeding assembly, in conjunction with the active feeding wheel 4, is used to control the intermittent rotation of the active feeding wheel 4.

[0018] Connecting block 6 is mounted on the swing gear 5, and spherical bearing 7 is mounted on connecting block 6.

[0019] In the adjustable-length feeding mechanism, the intermittent feeding assembly includes:

[0020] Motor 12, the output end of which is connected to a turntable via a belt;

[0021] A slider assembly 10 is disposed on the turntable. A slider pin 11 is slidably disposed inside the slider assembly 10. A connecting rod 8 is rotatably connected to the slider pin 11. A joint bearing 7 is disposed at one end of the connecting rod 8.

[0022] The oscillating gear 5 is rotatably mounted on one side of the active feeding wheel 4. The active feeding wheel 4 is equipped with a combined gear, and a one-way bearing is provided between the combined gear and the active feeding wheel 4. The combined gear and the oscillating gear 5 mesh with each other.

[0023] Furthermore, the connecting rod 8 is an adjustable length rod.

[0024] Motor 12 drives turntable 9 to rotate continuously via belt. Slider pin 11 drives connecting rod 8 to reciprocate in slider assembly 10. Through connecting rod 8 and spherical bearing 7, connecting block 6 is pushed to oscillate around gear center. Through gear meshing, the rotation of oscillating gear 5 is transmitted to active feed wheel 4 with combined gear. Active feed wheel 4 is equipped with a single bearing, so active feed wheel 4 can only rotate intermittently in one direction, thus realizing that the material belt is also intermittently fed to the left. By adjusting the length of connecting rod 8, the rotation angle of oscillating gear 5 is changed, thereby realizing different feeding lengths to meet the material requirements of different specifications of products.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
