Description

Technical Field

[0001] The utility model belongs to the technical field of sanitary napkin production equipment, and particularly relates to a waste sanitary napkin detection and rejection device. Background Technique

[0002] In the current production of sanitary napkins, after a series of production processes, quality inspection is finally required. The finished sanitary napkins are sequentially conveyed on a conveyor belt. When passing through a detection head, the defective sanitary napkins are quickly identified by a computer on the detection line. At the same time as the identification is completed, it is fed back to the conveyor belt, and the defective products are promptly removed by changing the conveying angle of the conveyor belt or by blowing air from a rejection head, ensuring that the produced sanitary napkins meet the factory requirements.

[0003] However, in today's rejection equipment, on the one hand, neither the angle change of the conveyor belt nor the air ejected from the rejection head can ensure the position where the sanitary napkins fall, resulting in difficult collection. On the other hand, since there is a gap between the feeding component and the discharging component, the conveyed sanitary napkins need to cross the rejection head during the pushing process for screening. Therefore, when conveying the sanitary napkins, it is necessary to keep the equipment with sufficient pushing and tensioning force, and the conveyor belt used for conveying needs to be kept in a taut state. The resulting consumable loss requires the equipment to be repaired from time to time. However, the current equipment requires more time for disassembly and repair, and the replacement of the conveyor belt cannot be completed in a short time, which will affect the production progress. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a waste sanitary napkin detection and rejection device. By arranging a guide cylinder below the air jet port, the sanitary napkins removed by air jet can be collected below along the direction of the guide cylinder. At the same time, by setting a tensioning component, the tension of the conveyor belt can be changed, and it is also convenient to disassemble and loosen, facilitating equipment maintenance and replacement of accessories.

[0005] To achieve the above object, the technical solution adopted by the utility model is:

[0008] The material removal component comprises an air jet port, which is arranged downward and connected to an air pump.

[0009] The sanitary napkin waste detection and rejection device adopts this structure, and guides and pushes the sanitary napkins conveyed on the conveyor belt through the feeding component, so that after passing the gap between the feeding component and the discharging component, they enter the discharging component for discharging. A rejection component is arranged above the gap passed by the sanitary napkin, and the air pump connected to the jet port sprays air after receiving the feedback signal, so as to spray the defective sanitary napkins downward to complete the rejection of the defective products. In order to ensure the stability of transmission, the feeding gap formed by two groups of upper and lower corresponding feeding components is connected to the discharging gap formed by two groups of upper and lower corresponding discharging components, and the transmission speed of the transmission belt thereon is synchronized, so that the sanitary napkin is sent out from the feeding gap and allowed to stay in the air for a short time, and then it is absorbed into the discharging gap to complete the transmission, and the sanitary napkins that stay in the air can also be more conveniently rejected by jetting.

[0010] In order to achieve synchronous transmission, the feeding component is composed of a driving roller, a transmission belt and two groups of elastic parts. The two groups of elastic parts and the driving roller stretch the transmission belt in a triangular shape and make the upper and lower ends of the feeding gap surrounded by the transmission belt stretched by the two groups of elastic parts. Therefore, in the process of driving the driving roller to rotate, the sanitary napkin in the feeding gap can be driven for transmission. Similarly, the discharging component is composed of a driving roller, a transmission belt, an elastic part and a driven roller. The elastic part, the driving roller and the driven roller stretch the transmission belt in a triangular shape and make the upper and lower ends of the discharging gap surrounded by the transmission belt stretched by the elastic part and the driven roller.

In order to tighten the transmission belt by pushing the support roller, a screw hole that passes through the movable groove is provided on the support seat, and a stud is screwed into the screw hole, and the end of the stud is abutted against the movable column. Therefore, in the process of gradually tightening the stud, the support roller will be continuously pushed onto the transmission belt, thereby tightening the transmission belt, and the tensioning force can also be changed with the depth of screwing. In order to avoid the support roller from falling during the process of replacing the transmission belt, a limiting long hole is provided on the movable column, and the limiting column is inserted into the limiting long hole and locked in the movable groove, thereby realizing the limiting hanging effect on the support roller, ensuring that the support roller remains connected to the support seat during the process of replacing the transmission belt.

[0012] Furthermore, the material removal component also includes a guide cylinder, the upper end surface of the guide cylinder is provided with a facing surface and a rear surface, the facing surface is provided with a feed port that passes through the guide cylinder, the facing surface faces the feed component, the rear surface faces the discharge component, and the air jet is vertically facing the feed port.

[0013] Compared with the prior art, the advantages of the present utility model are as follows: Through the feeding gap and discharging gap formed by the triangular feeding member / discharging member corresponding to each other, it is ensured that after the sanitary napkin stays in the air briefly during the synchronous transmission process, it is adsorbed into the discharging gap to complete the transmission.

[0028] Description of the working method of this utility model:

[0029] The sanitary napkin waste detection and rejection device adopting this structure guides and pushes the sanitary napkins conveyed on the conveyor belt through the feeding assembly 1, so that after passing over the gap between the feeding assembly 1 and the discharging assembly 2, they enter the discharging assembly 2 for discharging. A material rejection assembly 3 is arranged above the gap passed by the sanitary napkins. After receiving the feedback signal, the air pump connected to the air jet port 31 jets air, and sprays the defective sanitary napkins downward to complete the rejection of defective products. How to detect defective sanitary napkins and how to feedback signals here are all prior arts, so there is no need to elaborate too much on how to achieve defective product detection here.

[0030] To ensure the stability of transmission, through the feeding gap 12 formed by two sets of upper and lower corresponding feeding members 11, it corresponds to the discharging gap 22 formed by two sets of upper and lower corresponding discharging members 21. By synchronizing the transmission speed of the transmission belt 112 thereon, after the sanitary napkin is sent out from the feeding gap 12 and stays in the air briefly, it is adsorbed into the discharging gap 22 to complete the transmission. The sanitary napkin staying in the air can also be more conveniently jetted and rejected. A guiding cylinder 32 is arranged below the air jet port 31, and a feeding port 35 communicating with the guiding cylinder 32 is arranged on the facing surface 33 thereof. Therefore, when the sanitary napkin staying in the air is jetted by the air jet port 31, the sanitary napkin will enter the feeding port 35 downward and fall vertically under the guiding action of the guiding cylinder 32. A collecting appliance such as a receiving bucket can be placed below it to facilitate the recovery of defective products. The facing surface 33 faces the feeding assembly 1 and the back surface 34 is as close as possible to the discharging assembly 2, which can prevent the blown sanitary napkin from flying out from the gap between the back surface 34 and the discharging assembly 2.

[0031] In order to realize synchronous transmission, the feeding component 11 is composed of a driving roller 111, a transmission belt 112 and two groups of elastic components 113. The two groups of elastic components 113 and the driving roller 111 are in a triangular shape to open the transmission belt 112 and make the upper and lower ends of the feeding gap 12 surrounded by the transmission belt 112 opened by the two groups of elastic components 113. Therefore, in the process of driving the driving roller 111 to rotate, the sanitary napkin in the feeding gap 12 can be driven for transmission. Similarly, the discharging component 21 is composed of a driving roller 111, a transmission belt 112, an elastic component 113 and a driven roller 211. The elastic component 113, the driving roller 111 and the driven roller 211 are in a triangular shape to open the transmission belt 112 and make the discharging gap 12 The upper and lower ends of the gap 22 are surrounded by an elastic component 113 and a transmission belt 112 stretched by a driven roller 211. The driving roller 111, the transmission belt 112 and the elastic component 113 have the same structure as the feeding component 11. The same components can reduce the inventory of parts for maintenance and replacement, and can also reduce the difficulty of maintenance and replacement. The replacement of accessories is simple and can save replacement costs. Moreover, the same structural composition does not require adjustment of synchronization. The two sets of driving rollers 111 can be driven by the same set of motors, and the transmission belt 112 driven by them can also achieve synchronous transmission to ensure stable transmission of sanitary napkins. How to drive the driving roller 111 by a motor belongs to the prior art, so no excessive elaboration on how to achieve it will be given here.

[0032] For the convenience of equipment disassembly, repair and inspection, and also for adjusting the tightness of the transmission belt 112, the adjustment of the tension force is realized on the tensioning member 113 and disassembly is facilitated. With the rotating seat 1131 as the basis for support and angle adjustment, a support seat 1132 is provided thereon. The movable slot 1134 on the support seat 1132 cooperates with the movable column 1135 on the support roller 1133. More preferably, two sets of symmetrically arranged movable slots 1134 are provided, and the movable columns 1135 are arranged at the ends of the left and right ends of the support roller 1133. The two sets of movable columns 1135 are respectively inserted into the movable slots 1134, and then the transmission belt 112 is sleeved on the outer side wall of the support roller 1133, so that the transmission belt 112 on the feeding member 11 / discharging member 21 is triangular. At this time, the transmission belt 112 is in an untightened state, which facilitates the replacement of the transmission belt 112. In order to tighten the transmission belt 112 by pushing the support roller 1133, a threaded hole 1136 penetrating the movable slot 1134 is provided on the support seat 1132, and a stud 1137 is screwed therein. The end of the stud 1137 abuts against the movable column 1135. Therefore, during the process of gradually tightening the stud 1137, the support roller 1133 will be continuously pushed towards the transmission belt 112, thereby realizing the tightening of the transmission belt 112, and the tightening force can also be changed with the depth of screwing. In order to prevent the support roller 1133 from falling during the replacement of the transmission belt 112, a limiting long hole 1139 is provided on the movable column 1135, and a limiting column 1138 is inserted into the limiting long hole 1139 and locked in the movable slot 1134, realizing the limiting and hanging connection function of the support roller 1133, ensuring that the support roller 1133 remains connected to the support seat 1132 during the replacement of the transmission belt 112.

[0033] The beneficial effects of the present utility model are as follows: Through the feeding gap 12 and the discharging gap 22 formed by the corresponding triangular feeding member 11 / discharging member 21, it is ensured that after the sanitary napkin stays in the air briefly during the synchronous transmission process, it is adsorbed into the discharging gap 22 to complete the transmission. And through the adjustment of the position of the support roller 1133 of the tensioning member 113, the transmission belt 112 can be tightened by pushing the support roller 1133 during the process of screwing the stud 1137. During the process of gradually tightening the stud 1137, the support roller 1133 is continuously pushed towards the transmission belt 112 to realize the tightening of the transmission belt 112, and the tightening force can also be changed with the depth of screwing. The defective sanitary napkins in the air can enter the guide cylinder 32 along the feeding port 35 on the facing surface 33 under the blowing of the air jet port 31, realizing the collection of defective products.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
