Description

Technical Field

[0001] The utility model relates to a feeding mechanism of a tongue depressor packaging machine. Background Art

[0002] After the tongue depressors are fed in the tongue depressor packaging equipment, they are input into a heat sealing mechanism (or called a packaging mechanism, a sealing mechanism, a sealing device, etc.) to complete the sealing and packaging. The heat sealing mechanism includes a sealing roller for sealing. For example, in the packaging mechanism of the tongue depressor packaging machine of CN219668630U and the plate feeding device of the tongue depressor packaging machine of CN219635585U.

[0003] Efficient and stable feeding can improve the packaging efficiency. For example, a surrounding conveying component is used to cooperate with the conveying of the tongue depressors for feeding, and the tongue depressors are fed into the heat sealing mechanism for sealing and packaging. However, when there is a gap and lack of tongue depressors on the surrounding conveying component, it will cause an empty package situation in the subsequent sealing and packaging, and there will be no tongue depressor in the packaging bag. Summary of the Utility Model

[0004] In view of the technical problems existing in the background art, the technical problem to be solved by the utility model is to provide a feeding mechanism of a tongue depressor packaging machine that is efficient and stable during the feeding process, avoids feeding gaps, and avoids empty package situations.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions: The feeding mechanism of the tongue depressor packaging machine includes a surrounding conveying component. The surrounding conveying component has a feeding area, and the feeding direction of the feeding area is set from front to back. It is characterized in that: a tongue depressor gap filling device is also connected above the feeding area. The tongue depressor gap filling device includes a filling material bin, and the tongue depressor gap filling device is also equipped with a filling driving power component. A detection station is also provided in the feeding area of the surrounding conveying component. A sensor for detecting whether there is a tongue depressor on the surrounding conveying component is provided at the detection station. The sensor is arranged on the upper side or the lower side of the feeding area, and the sensor is located in front of the tongue depressor gap filling device. The sensor is connected to the filling driving power component.

[0006] The following various optimizations or supplementary explanations can be carried out on the above technical solutions respectively.

[0007] For example, the surrounding conveying component includes a surrounding conveying chain or a surrounding conveyor belt, and pusher heads are uniformly arranged on the surrounding conveying chain or the surrounding conveyor belt; the surrounding conveying chain or the surrounding conveyor belt is connected to a front driving wheel and a rear driving wheel, and the feeding area is arranged between the front driving wheel and the rear driving wheel.

[0008] For example, the feeding area includes a translational feeding section. The tongue depressor blank feeding device is correspondingly connected above the translational feeding section. The translational feeding section is also equipped with a material supporting platform. Limit gauges are provided on the left and right sides of the feeding area. The front end of the feeding area is the input side of the tongue depressor, and the rear end of the feeding area is the output side of the tongue depressor. The input side of the tongue depressor in the feeding area is connected to a tongue depressor input feeding device.

[0009] For another example, the lower end of the feeding bin is a material discharging opening. The tongue depressor blank feeding device further includes a feeding output material control component. The feeding output material control component is correspondingly connected to the feeding bin and is drivingly connected to the feeding driving power component.

[0010] For example, the lower end of the feeding bin is a material discharging opening. The tongue depressor blank feeding device includes a feeding output turntable and a shielding and sealing guiding component. The feeding output turntable serves as the feeding output material control component. The feeding output turntable is connected and configured below the material discharging opening. The feeding output turntable is provided with a material receiving accommodating opening. The lower end of the feeding output turntable is a discharging end, and the discharging end is connected to the surrounding conveying component below. The feeding output turntable is drivingly connected to the feeding driving power component. The feeding driving power component includes a feeding driving motor. The shielding and sealing guiding component is configured at the edge of the feeding output turntable and is connected between the material discharging opening and the discharging end.

[0011] Among them, the material receiving accommodating openings are evenly arranged on the circumferential edge of the feeding output turntable. In addition, the feeding output turntable can be a disc. The shielding and sealing guiding component has a shielding and sealing guiding surface. During the process of the tongue depressor being rotated by the feeding output turntable to output the material, the tongue depressor is blocked and sealed in the material receiving accommodating opening by the cooperation of the shielding and sealing guiding component. The upper end of the shielding and sealing guiding surface is the input end, and the lower end of the shielding and sealing guiding surface is the output end.

[0012] In addition, the shielding and sealing guiding surface can preferably be configured on the front side of the feeding output turntable. The feeding output turntable is circularly rotated and arranged, and the feeding output turntable rotates from top to bottom at the shielding and sealing guiding component. The shielding and sealing guiding surface includes an arc surface. The shielding and sealing guiding surface further includes a guiding surface, and the guiding surface is vertically connected to the arc surface.

[0013] Among them, the feeding bin has a vertical material discharging channel for the tongue depressors stacked in a horizontal and tiled state. The lower end of the vertical material discharging channel is the material discharging opening of the feeding bin.

[0014] The beneficial effect of the present utility model is that the feeding mechanism of the tongue depressor packaging machine can, when the surrounding conveying component conveys the tongue depressors, even if there are individual positions in the feeding area of the surrounding conveying component where there are blanks (lacking corresponding tongue depressors), timely detect and fill the blanks at the blank positions, so that the entire feeding process is efficient and stable, avoiding feeding blanks and avoiding the subsequent sealing from having empty packages.

Specific embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the implementation manners of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to the accompanying drawings, in the embodiment of this implementation manner, the feeding mechanism of the tongue depressor packaging machine includes a circumferential conveying component 1. The circumferential conveying component 1 can circulate and run in a closed loop in a cycle to efficiently and stably convey the tongue depressor for feeding. Among them, the circumferential conveying component 1 has a feeding area 2, that is, when the tongue depressor is conveyed on the circumferential conveying component 1, the tongue depressor is conveyed in the feeding area 2 of the circumferential conveying component 1. The feeding direction of the feeding area 2 (such as Figure 1It is arranged from front to back as shown by the middle feeding direction C, and the tongue depressor is conveyed from front to back in the feeding area 2.

[0025] The tongue depressor is continuously conveyed around the conveying member 1. The tongue depressors should be continuously arranged on the feeding area 2 of the circumferential conveying member 1. However, due to other factors, there are gaps of tongue depressors in the feeding area 2 of the circumferential conveying member 1. For example, when feeding the tongue depressors onto the circumferential conveying member 1, there is a break in the feeding, which will result in gaps of tongue depressors in the feeding area 2 of the circumferential conveying member 1, that is, there is no tongue depressor at the position where the tongue depressor should exist on the circumferential conveying member 1, which will cause a feeding gap (i.e., a vacancy) and lead to the problem of empty packages in subsequent packaging. The present utility model will solve this problem.

[0026] In the present utility model, a tongue depressor gap replenishing device 3 is also connected above the feeding area 2 of the circumferential conveying member 1. The tongue depressor gap replenishing device 3 cooperates to fill the gaps of the tongue depressors at the positions where the circumferential conveying member 1 has gaps (i.e., replenish the materials), ensuring continuous feeding and avoiding empty packages.

[0027] Among them, the tongue depressor gap replenishing device 3 includes a replenishing material bin 4, and the replenishing material bin 4 can store the tongue depressors for replenishment; the tongue depressor gap replenishing device 3 is also equipped with a replenishing driving power component 5 (i.e., a power source, such as a cylinder or a motor, etc.), and the replenishing driving power component 5 cooperates to drive the replenishing operation.

[0028] Among them, the feeding area 2 of the circumferential conveying member 1 is also equipped with a detection station 6, and a sensor 7 (such as a photoelectric eye sensor 7, etc.) for detecting whether there is a tongue depressor on the circumferential conveying member 1 is provided at the detection station 6, that is, the sensor 7 can detect whether there is a feeding gap (vacancy) of (tongue depressors) at this station.

[0029] Among them, the sensor 7 is arranged on the upper side or the lower side of the feeding area 2, which is convenient for setting and accurate detection. The sensor 7 is located in front of the tongue depressor gap replenishing device 3, ensuring that after detecting the gap position on the circumferential conveying member 1, the tongue depressor gap replenishing device 3 fills the gap position on the circumferential conveying member 1 with a tongue depressor at the rear. Moreover, in this structural layout, the gap position can be detected in advance without affecting the operation of the circumferential conveying member 1, and the circumferential conveying member 1 does not need to pause, with higher efficiency. The sensor 7 is connected to the replenishing driving power component 5 (to achieve signal transmission, which is a mature technology) so as to cooperate with the control of the replenishing driving power component 5, enabling the replenishing driving power component 5 to drive the replenishing operation corresponding to the detected gap position.

[0030] Regarding its working principle and function, the feeding mechanism of this tongue depressor packaging machine can, under the condition (premise) of conveying tongue depressors around the conveying component 1, even if there are individual empty positions (lack of corresponding tongue depressors) in the feeding area 2 of the circumferential conveying component 1, promptly detect and fill the empty positions with tongue depressors, making the entire feeding process efficient and stable, avoiding feeding gaps, and preventing empty packages from occurring in subsequent sealing.

[0031] Based on the above embodiments respectively, the following optimizations or further explanations can also be made.

[0032] For example, the circumferential conveying component 1 includes a circumferential conveying chain or a circumferential conveyor belt. Pushing heads 31 (such as pushing claws for pushing the tongue depressor forward) are evenly arranged on the circumferential conveying chain or the circumferential conveyor belt, which can cooperate to continuously convey the tongue depressor. The spacing between the front and rear pushing heads 31 can be adapted to the tongue depressor, being relatively more compact. Among them, the circumferential conveying chain or the circumferential conveyor belt is connected to the front driving wheel 27 and the rear driving wheel 29, that is, the circumferential conveying chain or the circumferential conveyor belt is wound around the front driving wheel 27 and the rear driving wheel 29 and runs in cooperation. The feeding area 2 is arranged between the front driving wheel 27 and the rear driving wheel 29. Of course, for the sake of structural layout, other auxiliary wheels can also be additionally arranged to cooperate with the circumferential conveying chain or the circumferential conveyor belt to run around. Even the transmission shafts corresponding to the front driving wheel 27 and the rear driving wheel 29 can cooperate with power input and power output for the transmission cooperation of the whole machine and other mechanisms. Of course, the transmission shafts can also be individually driven by a motor.

[0033] For another example, the feeding area 2 includes a translation feeding section. The translation feeding section can perform the translation conveyance of the tongue depressor, which is convenient for observation, detection, and replenishment. The tongue depressor empty position replenishment device 3 is correspondingly connected above the translation feeding section, and the replenishment is relatively stable. In addition, the translation feeding section is also equipped with a material supporting platform 8, which can support the conveyance of the tongue depressor (such as being pushed by the pushing head 31), being relatively more stable. Limit stop rules 9 (such as limit baffles) are also arranged on the left and right sides of the feeding area 2 to prevent deviation due to left and right displacement during the conveyance of the tongue depressor.

[0034] Among them, the front end of the feeding area 2 is the tongue depressor input side. Most of the tongue depressors are input from the front end onto the feeding area 2 of the circumferential conveying component 1 for subsequent conveyance. The rear end of the feeding area 2 is the tongue depressor output side, and the tongue depressor is output from the rear end and enters the next process (such as sealing and packaging). For example, a tongue depressor input feeding plate device is connected to the tongue depressor input side of the feeding area 2. The tongue depressor input feeding plate device cooperates to convey a large number of tongue depressors one by one onto the feeding area 2 of the circumferential conveying component 1. For example, the tongue depressor input feeding plate device can adopt a structure similar to the input structure of the tongue depressor empty position replenishment device 3 or other structures, which is not the technical problem solved by the present utility model and will not be elaborated further.

[0035] For example, the lower end of the feeding bin 4 is a feeding port 11, and the tongue depressor in the feeding bin 4 can discharge the feeding material from the feeding port 11 to coordinate the feeding. Among them, the tongue depressor idle feeding device 3 also includes a feeding output control component, which is correspondingly connected to the feeding bin 4, and the feeding output control component is used to coordinate and control whether the tongue depressor of the feeding bin 4 outputs the feeding material for feeding, and the feeding output control component is connected to the feeding drive power component 5 in a transmission manner. In the tongue depressor idle feeding device 3, the feeding output control component is driven by the feeding drive power component 5 to operate, and coordinates the feeding operation.

[0036] For example, the following structure is used to control the feeding operation, the lower end of the feeding silo 4 is a feeding port 11, the tongue depressor idle feeding device 3 includes a feeding output turntable 12 and a shielding and sealing material guiding component 13, the feeding output turntable 12 can be used as a feeding output control component, the feeding output turntable 12 is connected and configured below the feeding port 11, the feeding output turntable 12 is provided with a material receiving and accommodating port 14 (such as a groove port, which can be used to receive the tongue depressor falling from the feeding silo 4 and provide for the tongue depressor to be accommodated), the lower end of the feeding output turntable 12 is a discharging end 15, and the discharging end 15 is connected with the surrounding conveying component 1 below, so that the tongue depressor is transferred and output to the surrounding conveying component 1 through the feeding output turntable 12. The feeding output turntable 12 is connected to the feeding driving power component 5 by transmission, and the feeding output turntable 12 is driven by the feeding driving power component 5 to rotate and operate, and the feeding output turntable 12 is controlled to perform feeding operation. For example, the feeding driving power component 5 includes a feeding driving motor, and the feeding output turntable 12 can be set on the driving shaft 20 and driven by the feeding driving motor. In the figure, two feeding output turntables 12 are set on the driving shaft 20. The shielding and sealing material guiding component 13 is arranged at the edge of the feeding output turntable 12, and the shielding and sealing material guiding component 13 is connected between the blanking port 11 and the discharging end 15. When the tongue depressor is transferred and outputted from the blanking port 11 to the discharging end 15 by the feeding output turntable 12, the shielding and sealing material guiding component 13 cooperates with shielding, sealing and guiding to prevent the tongue depressor from being separated from the material receiving port 14 of the feeding output turntable 12 during the transfer and output process, so that the tongue depressor can smoothly output the feeding material from the blanking port 11 to the discharging end 15 to the surrounding conveying component 1.

[0037] The material receiving and accommodating openings 14 are evenly arranged on the circumferential edge of the replenishing material output turntable 12, and can be arranged in a uniformly divided distribution along the circumferential direction. The replenishing material output turntable 12 can operate quickly and efficiently, continuously and alternately transfer and convey the tongue depressors for output, enabling the tongue depressors in the replenishing material bin 4 to fall one by one for output, and the replenishing material output turntable 12 stably and efficiently outputs the tongue depressors one by one. The replenishing material output turntable 12 can adopt a disc; when the material receiving and accommodating opening 14 corresponds to the material dropping opening 11 of the replenishing material bin 4 above, the tongue depressor can fall into the material receiving and accommodating opening 14 and be transferred with the rotation of the replenishing material output turntable 12. Other positions on the circumferential edge of the replenishing material output turntable 12 (i.e., the positions between the material receiving and accommodating openings 14 and the material receiving and accommodating openings 14) can block the material dropping opening 11 of the replenishing material bin 4 until the next material receiving and accommodating opening 14 corresponds to the material dropping opening 11 above.

[0038] The shielding and sealing material guiding component 13 has a shielding and sealing material guiding surface 21. During the process of the tongue depressor being rotated and output by the replenishing material output turntable 12 for replenishing material, the shielding and sealing material guiding component 13 (the shielding and sealing material guiding surface 21 thereof) cooperates to block and seal the tongue depressor in the material receiving and accommodating opening 14, preventing the tongue depressor from detaching from the material receiving and accommodating opening 14 of the replenishing material output turntable 12 during the transfer and output process, so that the tongue depressor can smoothly output the replenishing material from the material dropping opening 11 to the discharge end 15 and onto the surrounding conveying component 1. In addition, the upper end of the shielding and sealing material guiding surface 21 is the input end, and the lower end of the shielding and sealing material guiding surface 21 is the output end, that is, the tongue depressor enters the area of the shielding and sealing material guiding surface 21 from the upper end.

[0039] In addition, the shielding and sealing material guiding surface 21 can be arranged on the front side of the replenishing material output turntable 12. The replenishing material output turntable 12 is circularly rotated and arranged. The replenishing material output turntable 12 rotates from top to bottom at the shielding and sealing material guiding component 13, can output smoothly, can be in the same feeding direction as the feeding area 2 of the surrounding conveying component 1, is not prone to material jamming, operates stably, and is more likely to fall into the empty position on the surrounding conveying component 1.

[0040] The shielding and sealing material guiding surface 21 includes an arc surface, and the shielding and sealing material guiding surface 21 further includes a guiding surface to ensure that the tongue depressor is guided by the shielding and sealing material guiding surface 21, and the guiding surface is vertically connected to the arc surface.

[0041] For example, the replenishing material bin 4 has a vertical material dropping channel 18 for laminating the tongue depressors in a horizontally tiled state. The lower end of the vertical material dropping channel 18 is the material dropping opening 11 of the replenishing material bin 4. It is more convenient to stack the tongue depressors, and the falling is smoother.
