Description

Technical Field

[0001] This utility model relates to the field of sodium carboxymethyl cellulose production technology, specifically to a weight inspection system for finished sodium carboxymethyl cellulose products. Background Technology

[0002] The finished sodium carboxymethyl cellulose is packaged in bags according to the required weight to meet customer needs, with the weight of the finished product in each bag required to be within a certain error range.

[0003] Currently, to ensure the finished product's weight meets requirements, it is generally weighed after packaging. Products that do not meet the weight requirements are rejected and repackaged. The earliest weighing involved manually placing the packaging bags on a weighing scale, followed by manual sorting. With the development of automation, the weighing process has been improved. Typically, an automatic weighing mechanism is installed on a conveyor belt. After weighing, the weight of the finished product is automatically detected. When the weight does not meet the requirements, a cylinder pushes the product to the side on the conveyor belt. Because sodium carboxymethyl cellulose is granular, the lateral pushing force required by the cylinder is relatively large, which can cause some damage to the product and packaging bags. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a weight inspection system for sodium carboxymethyl cellulose finished products.

[0005] This utility model is achieved through the following technical solution: a weight inspection system for sodium carboxymethyl cellulose finished product, comprising a weighing conveyor, a roller conveyor, and a discharge belt conveyor arranged in sequence, and a lateral conveyor. The roller conveyor includes multiple conveying rollers arranged side by side. The lateral conveyor includes a lateral conveying base located on one side of the roller conveyor, a drive shaft shafted to the lateral conveying base, multiple drive pulleys fixed to the drive shaft, and a drive motor for driving the drive shaft to rotate. The lateral conveyor also includes a lifting seat and a drive mechanism for driving the lifting seat to rise and fall. Multiple passive pulleys are shafted onto the lifting seat. The passive pulleys are arranged between adjacent conveying rollers, and a conveyor belt connects the passive pulleys and the drive pulleys.

[0006] As an optimization, one end of the lifting seat is fixedly connected to multiple passive pulley supports, the passive pulley shaft is connected to the passive pulley support, and the other end of the lifting seat is hinged to the drive shaft.

[0007] As an optimization, the drive mechanism includes a cylinder, the two ends of which are hinged to the lifting seat and the conveying base, respectively.

[0008] As an optimization, the weighing conveyor includes a weighing base and a feeding belt conveyor located above the weighing base, with a weighing sensor connected between the feeding belt conveyor and the weighing base.

[0009] As an optimization, the conveying base is provided with a defective product discharge channel on the side away from the roller conveyor mechanism. The defective product discharge channel includes an inclined roller frame and multiple discharge rollers axially connected to the roller frame.

[0010] As an optimization, the roller conveying mechanism further includes a roller conveying base, on which multiple lifting seats are fixedly connected, and the conveying roller shaft is connected to the lifting seats.

[0011] The beneficial effects of this utility model are as follows: The sodium carboxymethyl cellulose finished product weight inspection system of this utility model can automatically detect the weight of the finished product and transport products that do not meet the weight to the non-conforming product discharge channel through the side conveying mechanism. Therefore, the damage to the sodium carboxymethyl cellulose finished product is small, the product quality is improved, the whole process is automatically completed, the degree of automation is high, the structure is simple and easy to use.

[0024] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0025] like Figures 1-10 As shown, the present invention provides a weight inspection system for sodium carboxymethyl cellulose finished products, comprising a weighing conveyor 1, a roller conveyor 2, and a discharge belt conveyor 3 arranged in sequence. The packaged material passes through the weighing conveyor 1, the roller conveyor 2, and the discharge belt conveyor 3 in sequence.

[0026] like Figure 9 As shown, the weighing and conveying mechanism 1 includes a weighing base 11 and a feeding belt conveyor 13 located above the weighing base 11. A weighing sensor 12 is connected between the feeding belt conveyor 13 and the weighing base 11. Therefore, when the material is conveyed from the feeding belt conveyor 13, the weight of the material is detected by the weighing sensor 12 and fed back to the control system, so that products with unqualified weight can be rejected in the future.

[0027] like Figure 7 As shown, the roller conveyor mechanism 2 includes a roller conveyor base 21 and multiple parallel conveyor rollers 23. Multiple lifting seats 22 are fixedly connected to the roller conveyor base 21. The two ends of the conveyor rollers 23 are respectively axially connected to the lifting seats 22, which facilitates the arrangement of subsequent conveyor belts 44 between adjacent conveyor rollers 23. Double-row sprockets 24 are fixedly connected to the ends of the conveyor rollers 23. Adjacent conveyor rollers 23 are connected in sequence through the double-row sprockets 24. The motor drives any conveyor roller 23 to rotate, thereby driving all conveyor rollers 23 to rotate, realizing the conveying of materials.

[0028] The discharge belt conveyor 3 is connected to the discharge end of the roller conveyor mechanism 2, and the discharge belt conveyor 3 is used to transport qualified finished products outward.

[0029] It also includes a lateral conveying mechanism 4, which includes a lateral conveying base 41 located on one side of the roller conveying mechanism 2, a drive shaft 42 connected to the lateral conveying base 41, a plurality of drive pulleys 43 fixed to the drive shaft 42, and a drive motor 46 that drives the drive shaft 42 to rotate. The drive shaft 42 is perpendicular to the conveying roller 23 of the roller conveying mechanism 2. The upper end of the drive pulleys 43 is flush with the upper end of the conveying roller 23. The drive motor 46 drives the drive shaft 42 to rotate, thereby realizing the rotation of the plurality of drive pulleys 43.

[0030] The lateral conveying mechanism 4 also includes a lifting seat 47 and a driving mechanism for lifting the lifting seat 47. In this embodiment, the lifting seat 47 is located below the roller conveying mechanism 2. One end of the lifting seat 47 is fixedly connected to a plurality of passive pulley supports 49. Passive pulleys 45 are shaft-connected to the passive pulley supports 49. The passive pulleys 45 correspond one-to-one with the active pulleys 43. A conveyor belt 44 connects the passive pulleys 45 and the active pulleys 43. The passive pulleys 45 are arranged between adjacent conveying rollers 23.

[0031] The passive pulley 45 can move up and down with the lifting seat 47. Therefore, when the lifting seat 47 moves down, the conveyor belt 44 is located below the upper surface of the conveyor roller 23, which does not affect the normal conveying of the conveyor roller 23. When the lifting seat 47 moves up, the conveyor belt 44 rises above the upper surface of the conveyor roller 23, thereby lifting the material on the conveyor roller 23. The material is conveyed to the side by the movement of the conveyor belt 44.

[0032] In this embodiment, the other end of the lifting seat 47 is hinged to the drive shaft 42. Therefore, no matter how the lifting seat 47 moves up and down, the distance between the passive pulley 45 and the drive pulley 43 remains constant, thereby keeping the tension of the conveyor belt 44 constant.

[0033] The driving mechanism includes a cylinder 48, the two ends of which are hinged to the lifting seat 47 and the conveying base 41 respectively, so that the lifting seat 47 can be raised and lowered by the extension and retraction of the cylinder 48.

[0034] The conveying base 41 is provided with a defective product discharge channel 5 on the side away from the roller conveyor mechanism 2. The defective product discharge channel 5 includes an inclined roller frame 51 and a plurality of discharge rollers 52 axially connected to the roller frame 51.

[0035] How to use this utility model:

[0036] The packaging bags containing sodium carboxymethyl cellulose are conveyed forward on the feeding belt conveyor 13, the roller conveyor mechanism 2, and the discharging belt conveyor 3. The weight is detected by the weighing sensor 12. When the weight meets the requirements, the lateral conveying mechanism 4 does not operate.

[0037] When the weight does not meet the requirements, the cylinder 48 in the lateral conveying mechanism 4 extends, driving the lifting seat 47 to move upward, thereby causing the passive pulley 45 to move upward, raising the conveyor belt 44, lifting the packaging bag that has moved to this position, and then moving the packaging bag to the non-conforming product discharge channel 5 through the movement of the conveyor belt 44, and achieving sliding under the support of multiple discharge rollers 52.

[0038] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
