Description

Technical Field

[0001] This utility model belongs to the field of automatic feeding machine technology, specifically relating to an automatic toothpaste feeding machine. Background Technology

[0002] Hotel toiletries are typically packaged with a toothpaste tube and a toothbrush. Traditionally, the packaging process involves manual labor to fill the tubes. This method is labor-intensive, inefficient, and unsuitable for mass production. Furthermore, manual operation is prone to errors such as missed tubes. With technological advancements, automated packaging systems have emerged to replace manual labor. These systems rely on a feeding device to sequentially feed the loose, unordered toothpaste tubes into the packaging. Therefore, it is necessary to design a feeding device that can both replace manual feeding and ensure the orderly output of loose, unordered toothpaste tubes. Utility Model Content

[0003] The purpose of this invention is to provide an automatic toothpaste feeding machine to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] An automatic toothpaste feeding machine is characterized by comprising a feeding mechanism and a discharging mechanism mounted on a workbench. The discharging mechanism includes a hollow discharging bin, the interior of which is divided into multiple vertical discharging channels with openings at both the top and bottom by partitions. The discharging channels are used for toothpaste conveying and are provided with an inlet at the top and an outlet at the bottom. Each discharging channel has a first baffle at the top for controlling the opening and closing of the inlet, and a second baffle at the bottom for controlling the opening and closing of the outlet. Each first baffle is connected to a first cylinder, and each second baffle is connected to a second cylinder. The bottom of the discharging bin has a discharge port located below the discharging channels.

[0006] As a further improvement, the feeding mechanism includes a feeding hopper with an open top and a feeding conveyor belt inside. The feeding conveyor belt has multiple parallel first partitions fixedly installed on it. The top of the feeding conveyor belt extends obliquely upward from the top of the feeding hopper. A vibrating conveyor mechanism is provided on one side of the feeding hopper. The input end of the vibrating conveyor mechanism is located close to the feeding hopper. The feeding conveyor belt is located on the side close to the vibrating conveyor mechanism, and its output end extends out of the hopper and is located directly above the input end of the vibrating conveyor mechanism. The unloading bin is located at the output end of the vibrating conveyor mechanism.

[0007] As a further improvement, a return material mechanism is also included. The return material mechanism includes a return material conveyor belt with multiple parallel second partitions fixedly installed on it. An inclined first guide groove is provided on the side of the discharge bin away from the vibrating conveyor mechanism. The output end of the first guide groove is located above the input end of the return material conveyor belt. The output end of the return material conveyor belt is located close to the feeding hopper. A return port is provided on one side wall of the feeding hopper. An inclined second guide groove is provided at the output end of the return material conveyor belt. The output end of the second guide groove is connected to the return port.

[0008] As a further improvement, the vibrating conveying mechanism includes a linear vibrating feeder and a corrugated plate fixed on the top of the linear vibrating feeder. Baffles are provided on both sides of the corrugated plate, which are installed on the workbench and protrude from the conveying surface of the corrugated plate. Multiple conveying grooves are evenly distributed on the corrugated plate. The extension direction of the conveying grooves is from the feeding hopper to the unloading bin. The multiple conveying grooves correspond one-to-one with the multiple unloading channels.

[0009] As a further improvement, the top of the first baffle is inclined downward toward the first guide groove, so that when the first baffle is in the closed state, the toothpaste output by the vibration conveying mechanism slides into the first guide groove through the top inclined surface of the first baffle. The top of the first baffle is located close to the vibration conveying mechanism, the bottom of the first baffle is located close to the first guide groove, and the pistons of the plurality of first cylinders are arranged toward the direction of the first guide groove.

[0010] As a further improvement, the partition protrudes upward to form a feeding channel, and a first sensor is provided on the upward protrusion of the partition. Each feeding channel corresponds to a first sensor, a second sensor is provided in the middle of the feeding channel, and a third sensor is provided near the bottom of the feeding channel.

[0011] It also includes a controller, and the first sensor, the second sensor, the third sensor, the plurality of first cylinders and the plurality of second cylinders are all electrically connected to the controller.

[0012] The first sensor is used to detect whether there is material blockage above the feed inlet of the feeding channel, the second sensor is used to detect whether toothpaste enters the feeding channel, and the third sensor is used to detect whether the toothpaste in the feeding channel is output from the feeding channel.

[0013] As a further improvement, the bottom of the feeding hopper is herringbone shaped and is provided with a herringbone base plate. The herringbone base plate includes two connecting plates that are fixedly connected. There are two feeding ports, which are located on the two connecting plates of the herringbone base plate respectively. Each of the two feeding ports is provided with a third baffle. The two third baffles are driven by a third cylinder, which is electrically connected to the controller.

[0014] As a further improvement, a third conveyor belt and a fourth conveyor belt are respectively provided below the two third baffles, and the conveying directions of the third conveyor belt and the fourth conveyor belt are opposite.

[0015] As a further improvement, the side wall of the feeding hopper near the first guide channel is set as a transparent observation panel.

[0016] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0017] This utility model provides an automatic toothpaste feeding machine. By setting up a feeding mechanism, the controller controls a feeding channel containing toothpaste to open the corresponding second baffle. This ensures that only one piece of toothpaste is discharged from the feeding port of the feeding hopper at a time, which is beneficial for subsequent automatic packaging. This utility model can also be set with two feeding ports, each discharging one piece of toothpaste at a time.

[0018] By setting up a feeding mechanism and a vibrating conveyor mechanism, toothpaste can be continuously conveyed to the feeding channel after passing through the feeding conveyor belt under the action of the linear vibrating feeder and the corrugated plate. This can replace manual operation, reduce labor intensity, and improve production efficiency.

[0019] When a tube of toothpaste has entered the feeding channel, the first baffle closes. By setting up a return mechanism, the toothpaste that cannot enter the feeding channel or falls when the first baffle closes can be transported to the feeding hopper, so that the toothpaste can be circulated without manual recycling.

[0025] like Figure 1-3 As shown, an automatic toothpaste feeding machine includes a feeding mechanism 1 and a discharging mechanism 3 mounted on a workbench (not shown in the figure). The discharging mechanism 3 includes a hollow discharging bin 301, which is divided into multiple vertical discharging channels 302 with openings at both the top and bottom by partitions. Each discharging channel 302 has a first baffle 303 at its upper end for controlling the inlet switch and a second baffle 304 at its lower part for controlling the outlet switch. Each first baffle 303 is connected to a first cylinder 305, which drives the first baffle 303 to move. Each second baffle 304 is connected to a second cylinder 306. The second cylinder 306 drives the second baffle 304 to move. The bottom of the feeding bin 301 is provided with a feeding port. The partition protrudes upward to form a feeding channel. A first sensor 313 is provided on the upward protrusion of the partition. Each feeding channel corresponds to a first sensor 313. A second sensor 314 is provided in the middle of the feeding channel 302. A third sensor 315 is provided near the lower part of the feeding channel 302. The third sensor 315 is aligned with the toothpaste that falls in in the height direction. The first sensor 313, the second sensor 314, and the third sensor 315 may be, but are not limited to, photoelectric sensors. The second sensor 314 and the third sensor 315 are installed on the side wall of the feeding bin 301.

[0026] In this embodiment, the feeding mechanism 1 includes a feeding hopper 101 with an open top and a feeding conveyor belt 102 inside. Multiple parallel first partitions 103 are fixedly mounted on the feeding conveyor belt 102. The top of the feeding conveyor belt 102 extends obliquely upwards from the top of the feeding hopper 101. A vibrating conveyor mechanism 2 is located on one side of the feeding hopper 101. The feeding conveyor belt 102 is positioned near the input end of the vibrating conveyor mechanism 2, and its output end is located directly above the output end of the vibrating conveyor mechanism 2. A discharge bin 301 is located at the output end of the vibrating conveyor mechanism 2. The toothpaste in the feeding hopper 101 moves obliquely upwards with the feeding conveyor belt 102. The first partitions 103 prevent the toothpaste from rolling and falling during the movement. The toothpaste falls from the top of the feeding conveyor belt 102 to the input end of the vibrating conveyor mechanism 2.

[0027] In this embodiment, the vibrating conveying mechanism 2 includes a linear vibrating feeder 201 and a corrugated plate 202 fixed on the top of the linear vibrating feeder 201. The corrugated plate 202 has protruding corrugated plates 202 on both sides and baffles connected between the upper hopper 101 and the lower hopper 301. Multiple conveying grooves are evenly distributed on the protruding corrugated plate 202. The extension direction of the conveying grooves is from the upper hopper 101 to the lower hopper 301. The multiple conveying grooves correspond one-to-one with the multiple lowering channels 302. The linear vibrating feeder 201 causes the corrugated plate 202 to vibrate linearly, thereby causing the toothpaste to be conveyed forward in a row in the conveying trough and finally enter the corresponding unloading channel 302. Furthermore, the corrugated plate 202 can be provided with multiple sections. In this embodiment, it is provided with three sections. The output end of the first section near the hopper 101 is stacked above the input end of the second section, and the first and second sections are respectively connected to a vibrating feeder 201. The input end of the third section is located below the output end of the second section. The third section is tilted downwards towards the lower hopper 301, and the output end of the conveying trough is aligned with the feed inlet of the corresponding unloading channel 302.

[0028] In this embodiment, a return material mechanism 4 is also included. The return material mechanism 4 includes a return material conveyor belt 401. Multiple parallel second partitions 402 are fixedly provided on the return material conveyor belt 401 so that the toothpaste is evenly distributed on the return material conveyor belt 401. The side of the unloading hopper 301 away from the vibrating conveyor mechanism 2 is provided with a first guide groove 311 that is inclined downward toward the side of the return material conveyor belt 401. The output end of the first guide groove 311 is located above the input end of the return material conveyor belt 401. The output end of the return material conveyor belt 401 is located close to the loading hopper 101. A return material port is provided on one side wall of the loading hopper 101. The return material port is connected to a second guide groove 403 that is inclined downward toward the inner cavity and has an open top. The output end of the return material conveyor belt 401 is aligned with the upper port of the second guide groove 403. The top of the first baffle 303 is inclined downward toward the first guide groove 311. When the first baffle 303 is in the closed state, the high end of the first baffle 303 is located below the output end of the vibration conveying mechanism 2, and the low end is aligned with the first guide groove 311. The toothpaste output by the vibration conveying mechanism 2 falls into the first guide groove 311 through the inclined surface of the top of the first baffle 303, and enters the feeding hopper 101 from the return port through the conveying of the return conveyor belt 401, thereby realizing the circulation of toothpaste.

[0029] It also includes a controller, which may, but is not limited to, a PLC. The first sensor 313, the second sensor 314, the third sensor 315, the multiple first cylinders 305 and the multiple second cylinders 306 are all electrically connected to the controller.

[0030] Specifically, when the toothpaste sequentially passes the positions of the first sensor 313, the second sensor 314, and the third sensor 315, the first sensor 313, the second sensor 314, and the third sensor 315 successively send detection signals to the controller. The controller then sends commands to the solenoid valves based on these detection signals and controls the operation of the corresponding first cylinder 305 and second cylinder 306, thereby controlling the opening and closing of the first baffle 303 and the second baffle 304. Figure 2 As shown, when toothpaste falls onto the feed inlet during the process of sliding off the surface of the first baffle 303 but fails to enter the feed channel 302, the first sensor 313 (the installation height of the first sensor is consistent with the height of the toothpaste falling onto the feed inlet) sends a signal to the controller. The controller outputs a command to drive the first cylinder 305 to drive the first baffle 303 to push the toothpaste falling onto the feed inlet into the first guide groove 311. After pushing it in, the first baffle 303 is driven to reset, waiting for the toothpaste to fall in again.

[0031] After the toothpaste passes the location of the second sensor 314, the first cylinder 305 drives the first baffle 303 to close the inlet of the feeding channel 302, preventing subsequent toothpaste from entering the feeding channel 302; when the third sensor 315 detects that the toothpaste in the feeding channel is being discharged downwards from the outlet,

[0032] The first cylinder 305 drives the first baffle 303 to open the feed inlet of the feeding channel 302, while controlling the second baffle 304 to close the discharge outlet of the feeding channel 302, allowing toothpaste to enter the feeding channel 302.

[0033] During discharge, the controller opens the second baffle 304 corresponding to one of the toothpaste discharge channels 302, while the second baffle 304 in the other discharge channels 302 closes the discharge port of the corresponding discharge channel 302. The toothpaste is discharged from the discharge port of the discharge hopper 301 and enters the subsequent process for automatic packaging. Then the controller opens the second baffle 304 corresponding to another toothpaste discharge channel 302, and so on.

[0034] In this embodiment, the bottom of the feeding hopper 301 is provided with a herringbone-shaped third baffle 307. The third baffle 307 includes two fixedly connected connecting plates, and two discharge ports are respectively corresponding to the two connecting plates. There are two discharge ports. When discharging, the controller controls the two sides of the feeding channel 302 to drop one toothpaste into the discharge port on the same side, that is, it controls two toothpastes to fall at the same time. The third baffle 307 is driven by the third cylinder 308. The third cylinder 308 is electrically connected to the controller and is used to control the third baffle 307 to open after the toothpaste falls from the feeding channel 302.

[0035] In this embodiment, a third conveyor belt 309 and a fourth conveyor belt 310 are respectively provided below the two third baffles 307. The conveying directions of the third conveyor belt 309 and the fourth conveyor belt 310 are opposite, which can convey the toothpaste falling on them in the opposite direction and improve the conveying efficiency.

[0036] In this embodiment, the side wall of the feeding bin 301 near the first guide groove 311 is provided as a transparent observation plate 312. Specifically, the observation plate 312 can be made of tempered borosilicate glass. Through the observation plate 312, the operation of the feeding bin 301 can be observed at any time so that any abnormal situation can be dealt with in a timely manner.

[0037] In this embodiment, bulk toothpaste is first placed into the feeding hopper 101. The feeding conveyor belt 102 moves the toothpaste obliquely upward and drops it onto the corrugated plate 202. The linear vibrating feeder 201 at the bottom of the corrugated plate 202 causes the corrugated plate 202 to vibrate linearly and moves the toothpaste along the conveying trough, eventually entering the unloading channel 302. When the toothpaste passes the positions of the first sensor 313, the second sensor 314, and the third sensor 315 in sequence, the first sensor 313, the second sensor 314, and the third sensor 315 successively send detection signals to the controller. The controller sends commands to the first cylinder 305, the second cylinder 306, and the third cylinder 308 in sequence according to the detection signals, thereby controlling the opening and closing of the first baffle 303, the second baffle 304, and the third baffle 307, ultimately realizing that the toothpaste falls sequentially and orderly onto the third conveyor belt 309 and the fourth conveyor belt 310, facilitating subsequent automatic packaging. Toothpaste that fails to enter the discharge channel 302 falls onto the return conveyor belt 401 through the first guide groove 311. After passing through the return port, the toothpaste re-enters the feeding hopper 101. Repeating the above steps allows for continuous feeding.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
