Description

Technical Field

[0001] The utility model relates to a production device for non-woven fabrics and paper products, in particular to a folding, cutting and counting device for non-woven fabrics and paper products. Background Art

[0002] Non-woven fabric is a new type of environmentally friendly fabric made of polyester fiber. It is water-repellent, breathable, flexible, non-combustible, non-toxic and non-irritating, colorful and low cost. It is suitable for use in various industries such as sound insulation, heat insulation, masks, clothing, medical, personal care, etc.

[0003] As shown in the folding and slitting device for non-woven fabrics and paper products in Chinese patent CN114455380A, during the production process, non-woven fabrics are folded longitudinally, folded transversely, and slid to become cloth pieces. Since the processed cloth pieces are arranged in two rows, workers need to continuously take out the required number of cloth pieces and transfer them to the subsequent processing steps. However, the number of cloth pieces is estimated based on the workers' experience, which is not only cumbersome and slow, but also has large errors, is time-consuming and labor-intensive, and has low work efficiency, so it needs further improvement. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology and to provide a device for longitudinally folding, slitting and counting nonwoven fabrics and paper products, which should be easy to operate and have high working efficiency.

[0005] The technical solution of the utility model is:

[0006] A non-woven fabric and paper product folding, slitting and counting device comprises a longitudinal folding mechanism, a transverse folding mechanism and a slitting mechanism; the characteristics are that the longitudinal folding mechanism, the transverse folding mechanism and the slitting mechanism are all electrically connected to a controller; the longitudinal folding mechanism comprises a base, a guide plate swingably positioned on the base, and a guide plate driving assembly driving the guide plate to swing back and forth.

[0007] The guide plate driving assembly comprises a lifting cylinder for pushing the guide plate upward and a limit plate for controlling the lifting distance of the guide plate.

[0008] The limiting plate is provided with limiting bolts.

[0009] The transverse folding mechanism comprises a pair of pressing rollers and a pressing roller driving assembly for driving the pressing rollers to rotate.

[0010] The rotating shaft of the pressure roller is provided with a sensor; the controller is electrically connected to the sensor and the cylinder.

[0011] The slitting mechanism comprises a cutting knife and a supporting platform.

[0012] The beneficial effects of the utility model are:

[0013] The utility model improves the existing longitudinal folding mechanism. The guide plate can swing regularly as needed, thereby driving the height of the non-woven fabric to change, so that a piece of fabric at a certain position in the queue bulges upward as a mark. Workers directly take out the pieces of fabric from the mark, and the quantity fully meets the subsequent production requirements. Therefore, the utility model is easy to operate and has accurate counting, which greatly saves manpower and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] like Figure 1 As shown, the non-woven fabric and paper product folding, slitting and counting device comprises a longitudinal folding mechanism 1, a transverse folding mechanism 2, a slitting mechanism 3 and a controller.

[0028] The longitudinal folding mechanism, the transverse folding mechanism and the slitting mechanism are arranged along the moving direction of the nonwoven fabric ( Figure 2 The longitudinal folding mechanism is used to fold the nonwoven fabric in half longitudinally to reduce its width by half. The transverse folding mechanism is used to fold the nonwoven fabric in half transversely repeatedly to achieve layer-by-layer stacking. The slitting mechanism is used to cut the nonwoven fabric in half to form a sheet.

[0029] The transverse folding mechanism includes a pair of rollers 2-1 and a roller driving assembly (omitted in the figure) for driving the rollers to rotate in opposite directions. The slitting mechanism includes a cutter 3-1 and a support 3-2. The controller (omitted in the figure) is electrically connected to the longitudinal folding unit, the transverse folding mechanism, and the slitting mechanism.

[0030] The above structure is the same as the prior art.

[0031] The improvement of the utility model is that the longitudinal folding mechanism comprises a base 1-1, a guide plate 1-2, and a guide plate driving assembly. The guide plate is swingably positioned on the base, and the guide plate driving assembly is used to drive the guide plate to swing back and forth so that the top height of the guide plate changes.

[0032] The base is fixed to the frame of the device. The guide plate is triangular, and the guide plate is fixed on the swing plate 1-7 through a bracket 1-6, and the swing plate is swingably positioned on the base through a connecting shaft 1-8. A pair of horizontal guide rollers 1-9 are provided in front of the guide plate and a pair of vertical guide rollers 1-10 are provided in the rear.

[0033] The guide plate driving assembly includes a lifting cylinder 1-3 and a limiting plate 1-4.

[0034] The lifting cylinder is fixed on the base, and the telescopic rod of the lifting cylinder is arranged vertically upward and is used for pushing the swing plate above.

[0035] The limit plate is used to control the lifting distance of the guide plate. The limit plate is fixed on the base, and is provided with limit bolts 1-5, which are located above the swing plate. Rotating the limit bolts can change the distance between the limit bolts and the swing plate, thereby limiting the highest point position of the guide plate during movement.

[0036] The rotating shaft of the pressing roller is provided with a sensor (omitted in the figure) for monitoring the rotating speed of the pressing roller.

[0037] The controller is electrically connected to the sensor and the cylinder.

[0038] The working principle of the utility model is as follows:

[0039] 1. When counting is not required:

[0040] The nonwoven fabric 9 is first guided by a horizontal guide roller, then folded by a guide plate and pressed by a vertical guide roller to form a primary folded fabric 9-1, then folded horizontally by a pressing roller to form a secondary folded fabric 9-2, and finally cut by a cutter to form two rows of nonwoven fabric sheets 9-3 stacked on a support. Figure 8 At this time, the working principle of the utility model is the same as that of the prior art.

[0041] 2. When counting is required:

[0042] (1) Input the number of pieces to be counted on the controller;

[0043] (2) Each time the pressing rollers rotate one circle, the two pressing rollers perform a transverse folding action, thereby outputting two layers of secondary folded cloth 9-2 backward; after the cutting knife cuts, the secondary folded cloth 9-2 is separated from the left and right sides;

[0044] (3) The controller records the number of turns of the pressure roller. When the pressure roller is about to reach the set number of turns (the number of pieces counted), the lifting cylinder is started, the piston rod of the lifting cylinder extends upward and then retracts immediately, and the guide plate vibrates up and down once;

[0045] like Figure 5 , Figure 6 As shown, the guide plate is lifted up (swings clockwise), and after reaching the highest point, the guide plate falls down under the influence of gravity (swings counterclockwise), or rebounds and resets after hitting the limit bolt;

[0046] (4) Due to the swing of the guide plate, the non-woven fabric is temporarily lifted up, and the longitudinal folding line of the non-woven fabric changes (bulges upward);

[0047] The nonwoven fabric is first lifted up, and the longitudinal fold line of the nonwoven fabric is also raised synchronously ( Figure 6 After the guide plate is reset, the longitudinal fold line of the nonwoven fabric is immediately restored ( Figure 5 Horizontal dashed line);

[0048] (5) When the raised nonwoven fabric passes through the pressing roller, the pressing roller just rotates the set number of turns;

[0049] (6) After slitting, a raised non-woven fabric piece is produced at the same position in both the left and right columns of non-woven fabric pieces, and the raised non-woven fabric piece will appear regularly in the subsequent queue according to the requirement of the number of pieces counted.

[0050] like Figure 7 As shown, in the same queue, the number of intervals between the front and rear raised non-woven fabric pieces coincides with the number of pieces to be counted, which can be used as a mark 9-4 indicating the number. Workers take out the non-woven fabric pieces from the back to the front according to the mark (between the non-woven fabric piece at the end of the queue and the last mark). The operation is very convenient and there is no need to count the pieces manually or estimate based on experience. The counting is very accurate.

[0051] By turning the limit bolt, the swing angle of the guide plate can be adjusted, thereby controlling the protruding height of the non-woven fabric sheet.

[0052] All components of the utility model are prior art.

[0053] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
