Technical Field

[0001] The present application relates to the field of feeding devices, and in particular to a low-noise feeding device. Background Art

[0002] With the continuous advancement of technology, many metal products are gradually replaced by plastic products. More and more plastic products are used in our lives, which greatly facilitates our daily lives. Some plastic products are made by processing plastic particles. Plastic particles need to be fed during processing, so a feeding device is needed to obtain higher feeding efficiency.

[0003] The plastic pellet feeding device is an auxiliary device used to transport and feed the raw materials of the injection molding machine during the use of the injection molding machine so that it can work better. It has been widely used in the field of injection molding machine use; during the injection molding process, the general plastic pellets need to pass through the feeding device before entering the injection molding machine. In the prior art, the general injection molding machine is located on the first floor, and the collection box containing plastic pellets is on the workbench on the second floor. The hopper of the injection molding machine is connected to the collection box on the second floor through the conveying pipe of the feeding device, and the plastic pellets are sucked by the motor to complete the feeding.

[0004] With respect to the above-mentioned related technologies, the feeding device generates a large amount of noise when feeding materials to the hopper of the injection molding machine through a motor. Utility Model Content

[0005] In order to reduce the noise of a feeding device, the present application provides a low-noise feeding device.

[0006] The low-noise feeding device provided in this application adopts the following technical solution:

[0007] A low-noise feeding device comprises a conveying pipe, one end of which is connected to a collecting box, and the other end is connected to a hopper; the conveying pipe is inclined toward the hopper from the second floor to the first floor; the plastic particles enter the hopper by their own weight in the conveying pipe; the conveying pipe is provided with a knocking assembly, and the knocking assembly comprises a knocking hammer, a connecting rod and a bracket; the knocking hammer is arranged at one end of the connecting rod, the connecting rod is connected to the bracket, and the bracket is fixed to the second floor platform near the conveying pipe, and the knocking assembly can knock the conveying pipe to achieve the purpose of unblocking the conveying pipe.

[0008] By adopting the above technical solution, the plastic particles move downward in the inclined conveying pipe by their own gravity. When the plastic particles are not conveyed smoothly in the conveying pipe, the conveying pipe is unblocked by knocking with a knocking component. The feeding device avoids the continuous noise generated by the use of the motor, and also avoids the possibility of the motor absorbing impurities, thereby ensuring product quality. The device has a simple and practical structure, is easy to process and produce, and saves processing costs.

[0009] Optionally, the conveying pipe includes a first conveying pipe and a second conveying pipe; the first conveying pipe is located near the collecting box, and the second conveying pipe is located near the hopper; the first conveying pipe and the second conveying pipe are telescopically connected along the length direction of the conveying pipe.

[0010] By adopting the above technical solution, the retractable conveying pipe enables the device to adapt to hoppers within a certain range, and the feeding device can adjust the length of the conveying pipe according to the position of the hopper, so that the application range of the device is wider and the practicality of the device is increased.

[0011] Optionally, the diameter of the first delivery pipe is smaller than the diameter of the second delivery pipe, and the end of the first delivery pipe close to the second delivery pipe is sleeved on the second delivery pipe.

[0012] By adopting the above technical solution, plastic particles are transported from the first conveying pipe to the second conveying pipe. The first conveying pipe is sleeved in the second conveying pipe. The plastic particles move from the small diameter to the large diameter, avoiding the blockage of the plastic particles at the connection between the two and increasing the reliability of the device.

[0013] Optionally, the ends of the first delivery pipe and the second delivery pipe connected thereto are respectively provided with corrugations that match each other, and the first delivery pipe and the second delivery pipe are clamped together by the corrugations.

[0014] By adopting the above technical solution, the corrugated clamping connection can lock the relative position of the first conveying pipe and the second conveying pipe to prevent relative sliding between the two, so that the first conveying pipe and the second conveying pipe are relatively stable. The structure is simple and easy for workers to operate.

[0015] Optionally, the first conveying pipe is provided with a reinforcing pad, and the reinforcing pad is located at the contact position between the striking hammer and the first conveying pipe.

[0016] By adopting the above technical solution, the reinforcing pad can partially reinforce the delivery pipe. The reinforcing pad is arranged at the contact position between the percussion hammer and the delivery pipe, ensuring that the delivery pipe will not be deformed when the percussion hammer hits the delivery pipe. The use of the reinforcing pad makes the device more reliable.

[0017] Optionally, the reinforcement pad is provided on the first conveying pipe through a bolt clamp, and the reinforcement pad can be moved and locked along the length direction of the first conveying pipe.

[0018] By adopting the above technical solution, for hoppers at different distances, the relative positions of the first conveying pipe and the second conveying pipe are different, and the contact positions of the percussion hammer and the first conveying pipe are different. The reinforcement pad can be moved and locked along the length direction of the first conveying pipe, ensuring that the reinforcement pad can always be in the contact position between the percussion hammer and the first conveying pipe to protect the first conveying pipe.

[0019] Optionally, the delivery pipe is provided with a viewing window.

[0020] By adopting the above technical solution, the staff can observe the transportation situation in the delivery pipe through the window. When blockage occurs in the delivery pipe, the blockage position can be roughly determined through the window, thereby facilitating the staff to carry out subsequent unblocking work.

[0021] Optionally, a hopper cover is provided at one end of the second conveying pipe close to the hopper.

[0022] By adopting the above technical solution, the hopper cover can ensure that plastic particles will not splash when entering the hopper through the conveying pipe, and at the same time can ensure that foreign objects will not fall into the hopper, thereby increasing the reliability and practicality of the device and ensuring the quality of the finished product.

[0023] Optionally, the connecting rod is provided with a return spring, and the return spring drives the striking hammer away from the conveying pipe.

[0024] By adopting the above technical solution, the worker operates the connecting rod, and the connecting rod drives the percussion hammer to percuss the conveying pipe. When the worker releases the connecting rod, the percussion hammer is reset under the action of the reset spring, which is conducive to the worker to complete the continuous percussion action, helps to dredge the conveying pipe, and is conducive to the loading of the device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Plastic particles move downward in the inclined conveying pipe by their own gravity. When the conveying pipe is blocked, use the knocking component to knock to unclog the conveying pipe. This avoids the continuous noise generated by the use of the motor and the possibility of the motor absorbing impurities, ensuring product quality and increasing the practicality of the device;

[0027] 2. The setting of the viewing window enables the staff to observe the conveying conditions in the conveying pipe. When a blockage occurs in the conveying pipe, the blockage location can be roughly determined through the viewing window, thus facilitating the staff to carry out subsequent unblocking work;

[0028] 3. The reinforcing pad can partially reinforce the delivery pipe. The reinforcing pad is set at the contact position between the percussion hammer and the delivery pipe, ensuring that the delivery pipe will not be deformed when the percussion hammer hits the delivery pipe. The reinforcing pad can be moved and locked along the length direction of the first delivery pipe, ensuring that the reinforcing pad can always be in the contact position between the percussion hammer and the first delivery pipe to protect the first delivery pipe. The use of the reinforcing pad increases the practicality and reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application embodiment discloses a low noise feeding device. Figure 1 and Figure 2A low-noise feeding device includes a conveying pipe 1, and the two ends of the conveying pipe 1 are respectively connected to the collection box on the second floor and the hopper on the first floor; the conveying pipe 1 is inclined toward the hopper from the second floor to the first floor. The conveying pipe 1 includes a first conveying pipe 11 and a second conveying pipe 12. The first conveying pipe 11 is located on the side of the collection box close to the second floor platform and is connected to the collection box. The second conveying pipe 12 is located on the side of the hopper close to the injection molding machine. The second conveying pipe 12 is fixedly connected to a horizontally arranged hopper cover 5 at one end close to the hopper. The hopper cover 5 covers the top of the hopper to prevent the splashing of plastic particles. The diameter of the first conveying pipe 11 is smaller than that of the second conveying pipe 12, and the end of the first conveying pipe 11 close to the second conveying pipe 12 is sleeved on the second conveying pipe 12. The contact ends of the first conveying pipe 11 and the second conveying pipe 12 are respectively provided with multiple sections of corrugations 13 that cooperate with each other. The corrugations 13 are located on the outer wall of the first conveying pipe 11 and the inner wall of the second conveying pipe 12, and the corrugations 13 are arranged along the circumferential direction of the conveying pipe 1. The first conveying pipe 11 and the second conveying pipe 12 can be extended and locked by connecting the corrugations 13 at different positions. The first conveying pipe 11 and the second conveying pipe 12 are each provided with a window 4 at the middle position along the length direction. The window 4 is located on the side wall of the conveying pipe 1 close to the ground. The staff can observe the conveying situation in the conveying pipe 1 through the window 4 on the first floor. A knocking component 2 is provided at one end of the first conveying pipe 1 close to the collection box. When the plastic particles in the conveying pipe 1 are blocked, the conveying pipe 1 can be unblocked by knocking the conveying pipe 1 with the knocking component 2.

[0036] The retractable conveying pipe 1 can be adapted to hoppers located at different positions within a certain range. The plastic particles move downward in the inclined conveying pipe 1 by their own gravity. If the plastic particles are not transported smoothly in the conveying pipe 1, the situation in the conveying pipe 1 can be observed through the window 4, and the blockage position in the conveying pipe 1 can be roughly determined. The conveying pipe 1 can be unblocked by knocking with the knocking component 2. The feeding device is used to feed materials, which avoids the continuous noise generated by the motor. The device has a simple and practical structure, is easy to process and produce, and saves processing costs. At the same time, it also avoids the possibility of the motor absorbing impurities, ensuring product quality.

[0037] Reference Figure 1, the knocking assembly 2 includes a knocking hammer 21, a connecting rod 22 and a bracket 23. The knocking hammer 21 is fixed to one end of the connecting rod 22. The connecting rod 22 is hinged to the bracket 23 on one side of the middle position along the length direction. The bracket 23 supports the connecting rod 22 and the knocking hammer 21, and the bracket 23 is vertical and fixed to the second floor platform near the position of the first conveying pipe 11. Press down the end of the connecting rod 22 away from the knocking hammer 21, and the knocking hammer 21 can contact and knock the first conveying pipe 11. The first conveying pipe 11 and the knocking hammer 21 are detachably connected with a reinforcing pad 3 at the contact position between the first conveying pipe 11 and the knocking hammer 21. The reinforcing pad 3 is in the shape of two semicircles, and the diameter of the reinforcing pad 3 is equal to the outer diameter of the first conveying pipe 11. The two semicircular parts of the reinforcing pad 3 are bolted to the outer wall of the first conveying pipe 11. The connecting rod 22 is fixed with a reset spring 24 between the knocking hammer 21 and the bracket 23, and the reset spring 24 gives the connecting rod 22 a force to connect the end of the knocking hammer 21 away from the conveying pipe 1. The use of the reinforcing pad 3 avoids the possibility that the percussion hammer 21 directly hits the conveying pipe 1, causing the conveying pipe 1 to deform. The detachable connection of the reinforcing pad 3 ensures that the position of the reinforcing pad 3 on the first conveying pipe 11 is movable, and the position of the reinforcing pad 3 can be adjusted according to the different lengths of the conveying pipe 1. When the staff presses down the end of the connecting rod 22 away from the percussion hammer 21, the percussion hammer 21 moves upward to hit the conveying pipe 1. When the staff releases the connecting rod 22, the percussion hammer 21 moves downward under the action of the reset spring 24 to complete the reset, which is conducive to the workers to complete the continuous percussion action.

[0038] The implementation principle of a low-noise feeding device in the embodiment of the present application is as follows: the length of the conveying pipe 1 is adjusted according to the distance between the hopper and the collection box, and the conveying pipe 1 is connected. The plastic particles in the collection box on the second floor enter the inclined conveying pipe 1, and enter the hopper through the conveying pipe 1 by their own gravity. The staff can observe the conveying of plastic particles through the window 4. When the plastic particles are blocked in the conveying pipe 1, the staff can use the knocking component 2 on the second floor platform to knock the conveying pipe 1 to dredge the conveying pipe 1, so as to ensure that the conveying pipe 1 can smoothly convey the plastic particles.

[0039] The embodiment of the present application has the effect of reducing the noise of the loading device.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
