Description

Technical Field

[0001] The utility model belongs to the technical field of bowling production equipment, and particularly relates to a ball core feeding device. Background Art

[0002] A bowling ball is a spherical object with many small round holes and is used for bowling games in a bowling alley. The manufacturing process of a bowling ball includes material preparation, ball shell manufacturing, weight adjustment, and surface treatment.

[0003] The core materials for bowling ball manufacturing include a ball core and a ball shell. The ball core is usually made of high-density polyurethane or other high-density materials, while the ball shell is made of polyester resin or polyurethane resin. During the manufacturing process,

[0004] it is necessary to select appropriate raw materials and conduct sufficient stirring and mixing. The ball core is the core part of a bowling ball and plays a crucial role in the performance and controllability of the ball. The process of manufacturing the ball core includes melting of the ball core material, feeding the mold, and cooling. During the process of feeding the ball core mold, since the ball core raw material is relatively viscous, the conveyor belt needs to wait for the discharge pipe to be emptied during the process of transporting the ball core mold to ensure that as much material as possible falls into the mold, so as to prevent excess material from dripping onto the conveying device. This necessary waiting time significantly reduces the feeding efficiency of the mold. Therefore, the utility model proposes a ball core feeding device to prevent material dripping, avoid pollution of the surface of the conveying device by the material, ensure the cleanliness and efficiency of the production process, and at the same time ensure the feeding efficiency.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0018] Please refer toFigure 1-2 , the present utility model provides the following technical solutions: a spherical center feeding device, which comprises a frame 1. Above the frame 1, a feeding mechanism and a controller 12 are respectively installed. The core component of the feeding mechanism is a feeding cylinder 2, and the barrel body of the feeding cylinder 2 is firmly installed on the frame 1. On one side of the inner top of the feeding cylinder 2, a feed pipe 3 is provided for guiding materials to enter. Inside the feeding cylinder 2, a piston 4 is installed, which is responsible for pushing and discharging materials. A cylinder 5 is fixed on the top of the feeding cylinder 2, and the output end of the cylinder 5 precisely passes through the center of the top end of the feeding cylinder 2 and is tightly connected to the piston 4. The piston 4 is driven to move up and down by air pressure, thereby controlling the addition and discharge of materials. An outlet 6 is opened at the center of the bottom end of the feeding cylinder 2, and a diverter is equipped here. The diverter mainly includes a discharge pipe 7, and a ventilation pipe 8 is connected to one side of the discharge pipe 7. A material valve 9 is installed on the top pipe body of the discharge pipe 7 for opening and closing the outlet 6. A wind valve 10 is installed at the connection of the ventilation pipe 8 and the discharge pipe 7 for regulating the on-off of the air flow. One end of the ventilation pipe 8 is connected to an air pump, and the necessary air flow power is provided by the air pump.

[0019] In order to ensure accurate metering and conveying, in this embodiment, as a preferred technical solution of the present utility model, one end of the feed pipe 3 is connected to a storage tank 12, and a peristaltic pump 11 is installed on the pipe body of the feed pipe 3.

[0020] In order to achieve automatic control, in this embodiment, as a preferred technical solution of the present utility model, the controller 12 is electrically connected to the peristaltic pump 11, the material valve 9, the wind valve 10, the air pump and the cylinder 5 respectively.

[0021] In order to prevent materials from sticking to the inner walls of the feeding cylinder 2 and the discharge pipe 7, in this embodiment, as a preferred technical solution of the present utility model, the inner walls of the feeding cylinder 2 and the discharge pipe 7 are both coated with a non-stick coating 13, and the non-stick coating 13 is a Teflon coating.

[0022] In order to ensure that the materials can be smoothly extruded, in this embodiment, as a preferred technical solution of the present utility model, the piston 4 is made of rubber material.

[0023] In summary, by means of the above technical solution of the present utility model, during use, a control signal is output through a program preset by the controller 12, and then the number of rotations of the motor in the peristaltic pump 11 is controlled to achieve accurate metering and conveying. During this process, the raw materials in the storage tank 12 are pumped into the feeding cylinder 2 through the feeding pipe 3. When the driving motor in the peristaltic pump 11 completes the preset number of rotations, its built-in encoder converts the feedback signal into an electrical signal and transmits it to the controller 12. After receiving this electrical signal, the controller 12 converts the input signal into electrical signals for controlling the output of the cylinder 5 and opening the material valve 9 according to its internal program. Subsequently, the output of the cylinder 5 drives the piston 4 to descend, thereby quickly extruding the raw materials inside the feeding cylinder 2 from the discharge pipe 7 of the diverter into the spherical mold. When the cylinder 5 completes its output task, its own sensor feeds back the corresponding signal to the controller 12, and the controller 12 accordingly controls the material valve 9 to close again and opens the air valve 10 to make the peristaltic pump 11 start working again and the air pump starts to pump air. During this process, the conveying device transfers the mold to the next position. It should be noted that during the air pumping process of the air pump, suction is generated at the bottom of the discharge pipe 7 through the ventilation pipe 8 to ensure that the materials at the bottom nozzle of the discharge pipe 7 do not fall. The above steps will be cycled to achieve a continuous and efficient material conveying and processing process, and the materials will not drip either.

[0024] Finally, it should be noted that: in the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "setting", "connection", "fixation", "swivel connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
