Description

Technical Field

[0001] The utility model relates to the technical field of easy-pull lid production equipment, and in particular to an active lid dropper. Background Art

[0002] In the production process of food and beverage caps, the use of cap droppers is extremely extensive during the cap transmission process. For example, they are inevitably used in the feeding system of the glue injection machine and the assembly machine. The traditional cap dropper relies on the friction of the cap dropper wheel to adjust the balance of thrust and resistance in the entire pipeline. However, it is difficult to grasp the balance. Too much friction will increase the thrust, and the caps will squeeze each other in the pipe cage, which is easy to scratch and damage the coating and affect the quality. Too little friction will easily break the balance of friction and thrust, and the caps in the pipeline will fall and cause the machine to stop. Utility Model Content

[0003] The utility model aims to provide an active cap dropper to solve the problem of reduced production efficiency and lowered product quality due to improper adjustment of the cap dropper during the cap production process.

[0004] In order to achieve the above objectives, the utility model provides the following technical solutions:

[0005] The utility model provides an active cover dropper, comprising a pair of mounting and fixing plates, a pair of cover drop wheels and a pair of stepper motors, wherein the pair of mounting and fixing plates are arranged in parallel, the pair of cover drop wheels can be rotatably mounted between the two mounting and fixing plates, a cover passage matching with an easy-pull cover is formed between the two cover drop wheels, the pair of stepper motors are mounted on a side of one of the mounting and fixing plates facing away from the cover drop wheels, and are connected to the two cover drop wheels in a one-to-one correspondence to drive the cover drop wheels to rotate.

[0006] Furthermore, the active cover drop device also includes an adjusting screw, and the adjusting screw is used to adjust the distance between the two cover drop wheels.

[0007] In one embodiment, the adjusting screw is passed through the mounting plate and tightens the cover drop wheel.

[0008] In one embodiment, the axis of the adjusting screw is perpendicular to the axis of the cover-dropping wheel.

[0009] In one embodiment, a receiving groove is formed on the mounting plate, the cover drop wheel is connected with an abutment block, the abutment block is placed in the receiving groove, and the end of the adjustment screw abuts against the abutment block and can push the abutment block to move in the receiving groove.

[0010] The beneficial effect brought about by the technical solution provided by the utility model is that the active cover dropper of the utility model drives the cover drop wheel to rotate by setting a stepper motor to act on the cover, changes the passive drive into an active drive, reduces the transmission resistance of the cover, and improves the quality problems such as deformation and scratching of the cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following briefly introduces the drawings required for describing the embodiments of the present utility model.

[0012] Figure 1 The present invention is a schematic structural diagram of an active cover dropper provided in one embodiment of the present invention. DETAILED DESCRIPTION

[0013] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not intended to limit the scope of protection of the present invention.

[0014] It should be understood that the various steps described in the method implementation of the present utility model can be performed in different orders and / or performed in parallel. In addition, the method implementation may include additional steps and / or omit the steps shown. The scope of the present utility model is not limited in this respect.

[0015] The term "including" and its variations used herein are open inclusions, i.e., "including but not limited to". The term "connected" may be directly connected or indirectly connected through intermediate components (elements). The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". The relevant definitions of other terms will be given in the following description.

[0016] It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0017] See also Figure 1The utility model relates to an active cover dropper, comprising a pair of mounting plates 10, a pair of cover drop wheels 30 and a pair of stepper motors 20. The pair of mounting plates are arranged in parallel, and the pair of cover drop wheels can be rotatably mounted between the two mounting plates. A cover passage 40 cooperating with an easy-open cover is formed between the two cover drop wheels. The pair of stepper motors are mounted on a side of one of the mounting plates facing away from the cover drop wheels, and are connected to the two cover drop wheels one by one to drive the cover drop wheels to rotate.

[0018] Without the drive of a stepper motor, the cap can only be moved forward when the thrust of the cap pusher at the front end of the cap dropper is greater than the friction of the cap dropper wheel. At this time, a problem will arise: the cap between the cap dropper wheel and the cap pusher wheel plays the role of transmitting thrust, and is also squeezed by the force. If it is not adjusted properly, it will cause deformation and scratches on this section of the cap, affecting product quality. The improved cap dropper solves the problem of cap extrusion and deformation. When the front end cap pusher pushes the cap, the stepper motor acts synchronously, and the possibility of the cap in the pipeline being squeezed is greatly reduced.

[0019] Furthermore, the active cover dropper also includes an adjusting screw 50, which is used to adjust the distance between the two cover drop wheels. The distance between the two cover drop wheels can be changed by adjusting the adjusting screws on both sides of the mounting plate, thereby changing the friction force applied by the cover drop wheels to the cover.

[0020] In one embodiment, the adjusting screw is passed through the mounting plate and tightens the cover drop wheel.

[0021] In one embodiment, the axis of the adjusting screw is perpendicular to the axis of the cover-dropping wheel, so that the distance between the two cover-dropping wheels can be adjusted more accurately, thereby achieving accurate adjustment of the friction force.

[0022] In one embodiment, a receiving groove 11 is formed on the mounting plate 10, and the cover drop wheel is connected with an abutment block 31, which is placed in the receiving groove. The end of the adjusting screw abuts against the abutment block and can push the abutment block to move in the receiving groove.
