Description

Technical Field

[0001] This utility model belongs to the technical field of weighing and packaging, specifically a mobile weighing and packaging machine. Background Technology

[0002] In automated packaging in industries such as food, chemicals, and feed, weighing, filling, and sealing are the three core processes. Current technology generally employs a "split-fixed" solution where three independent pieces of equipment—an electronic quantitative scale, a belt conveyor, and a sealing machine—are rigidly fixed to the ground. This results in immobile equipment, requiring foundation reconstruction for workstation adjustments, which is time-consuming; manual handling of bags to connect weighing and sealing is labor-intensive and prone to spillage; and the welded support frame has no height adjustment, making its use passive. Although mobile stand-alone machines with casters have emerged in recent years, they still do not achieve integrated continuous operation of "weighing-conveying-sealing," and the support lacks height adjustment. Therefore, a mobile weighing and packaging machine needs to be developed to solve these technical problems. Utility Model Content

[0003] To address the above problems, this utility model provides a mobile weighing and packaging machine to solve the technical problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A mobile weighing and packaging machine includes a base plate, a body mounted on one side of the base plate, and a hopper, a first valve, a weighing hopper, a weighing sensor, a second valve, a fixing plate, a bag clamping mechanism, and a bag clamping outlet arranged from top to bottom on the body. A belt conveyor is mounted on the base plate via a support assembly. The support assembly includes a support base with multiple through holes in the middle, one of which has a second bolt. The support base has oblong holes on both sides, with the first bolt movably mounted within each oblong hole. A seat body is mounted at the lower end of the support base, and a mounting plate is mounted at the lower end of the seat body. One side of the belt conveyor is connected to a drive device. A sealing assembly is mounted on one side of the body.

[0006] As a further improvement to the above solution, the support base includes a concave groove, with connecting ears on both sides of the concave groove, and the concave groove has a U-shaped structure.

[0007] As a further improvement to the above solution, the through hole is set on the concave groove, and the waist-shaped hole is set on the connecting lug.

[0008] As a further improvement to the above scheme, the base is made of channel steel.

[0009] As a further improvement to the above solution, a support frame is provided at the bottom of the base plate via a vertical plate.

[0010] As a further improvement to the above solution, the sealing assembly includes a sealing device, which is mounted on a mounting base, and an electric push rod is provided on the side of the mounting base; the mounting base is mounted on a guide rail, and the guide rail is mounted on a horizontal plate.

[0011] As a further improvement to the above solution, guardrails are installed on both sides of the belt conveyor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention provides a mobile weighing and packaging machine. By integrating the belt conveyor into the base plate and employing a support component design, the machine achieves overall mobility, avoiding the inefficiency of traditional fixed equipment that requires manual handling of bags. The through holes and oblong holes of the support base, combined with bolt adjustments, can quickly adapt to bag heights. Simultaneously, the linkage design between the bag clamping mechanism and the belt conveyor ensures continuous operation from weighing to sealing, significantly improving production efficiency.

[0014] The composite structure of the concave groove and U-shaped connecting ear in this invention not only enhances the bending strength of the support seat, but also provides double-sided limiting for the belt conveyor to prevent deviation during operation.

[0015] In this invention, the through hole is located in the concave groove body and the waist-shaped hole is located in the connecting ear, which realizes the adjustment of the support height and solves the problem that traditional welding brackets cannot adapt to bags of various specifications.

[0016] The electric push rod driven sealing device in this invention can automatically track the position of the bag opening along the guide rail and adapt to different bag lengths.

[0017] The guardrails on both sides of the belt conveyor in this invention can prevent the bags from tipping over or slipping during transport. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0024] like Figure 1-4 As shown, the specific solution of this embodiment is as follows: a mobile weighing and packaging machine includes a base plate 1, a body 6 is arranged on one side of the base plate 1, and a hopper 7, a first valve 8, a weighing hopper 9, a weighing sensor 10, a second valve 11, a fixing plate 12, a bag clamping mechanism 13 and a bag clamping outlet 17 are arranged on the body 6 from top to bottom. A belt conveyor 3 is arranged on the base plate 1 through a support assembly 5. The support assembly 5 includes a support base 51, a plurality of through holes 53 are arranged in the middle of the support base 51, a second bolt 55 is arranged in one of the through holes 53, and waist-shaped holes 52 are arranged on both sides of the support base 51. A first bolt 54 is movably arranged in the waist-shaped holes 52. A seat body 56 is arranged at the lower end of the support base 51, and a mounting plate 57 is arranged at the lower end of the seat body 56. One side of the belt conveyor 3 is connected to a drive device 2. A sealing assembly 16 is arranged on one side of the body 6.

[0025] As a preferred embodiment of the above, the support base 51 includes a concave groove 511, and connecting ears 512 are provided on both sides of the concave groove 511. The concave groove 511 is provided with a U-shaped structure.

[0026] As a preferred embodiment of the above, the through hole 53 is provided on the concave groove 511, and the waist-shaped hole 52 is provided on the connecting ear 512.

[0027] As a preferred embodiment of the above, the base 56 is provided as a channel steel.

[0028] As a preferred embodiment of the above, the bottom end of the base plate 1 is provided with a support frame 15 via a vertical plate 14.

[0029] As a preferred embodiment of the above, the sealing assembly 16 includes a sealing device 161, which is mounted on a mounting base 162. An electric push rod 163 is provided on the side of the mounting base 162. The mounting base 162 is mounted on a guide rail 165, which is mounted on a horizontal plate 164.

[0030] As a preferred embodiment of the above, guardrails 4 are provided on both sides of the belt conveyor 3.

[0031] Working principle

[0032] The entire machine uses the base plate 1 as a movable base. The weighing sensor 10 detects the weight of the material in the weighing hopper 9 in real time. The PLC controls the opening and closing of the first valve 8 and the second valve 11 according to the set value. The belt conveyor 3 maintains the optimal drop between itself and the bag discharge port 17 under the adjustment of the support component 5, so as to achieve a smooth transition of the bag material. The sealing component 16 drives the sealing device 161 to move along the guide rail 165 through the electric push rod 163, so that the sealing center is always aligned with the bag opening. The through hole 53 and the waist-shaped hole 52 of the support component 5 provide height adjustment capability to meet different bag specifications. The channel steel base 56 and the guardrail 4 together ensure the stability of the belt conveyor 3 when running at high speed.

[0033] Work process

[0034] 1. Preparation stage

[0035] Push the entire machine to the target workstation and fix it to the ground by the support frame 15 under the base plate 1.

[0036] Based on the bag height, loosen the second bolt 55, select a suitable through hole 53 on the support 51 and tighten it again to complete the initial adjustment of the belt conveyor 3. Loosen the first bolt 54 and use the oblong hole 52 to fix it again.

[0037] 2. Weighing and filling

[0038] The empty bag is manually placed onto the clamping mechanism 13, triggering a clamping signal.

[0039] The PLC opens the first valve 8, and the material enters the weighing hopper 9 from the hopper 7; the weighing sensor 10 provides real-time feedback on the weight, and after reaching the set value, the first valve 8 is closed and the second valve 11 is opened, and the material is poured into the bag through the bag outlet 17.

[0040] 3. Conveying transition

[0041] After filling is completed, the bag clamping mechanism 13 is released, and the bag falls onto the belt conveyor 3; the drive device 2 is started, and the bag moves with the belt to the sealing station; the guardrail 4 prevents the bag from tipping over or running off course.

[0042] 4. Automatic sealing

[0043] When the bag reaches the sealing area, the photoelectric switch detects the height of the bag opening, and the electric push rod 163 drives the mounting base 162 to move along the guide rail 165, so that the sealing device 161 is precisely aligned with the bag opening.

[0044] After the sealing device 161 completes heat sealing or sewing, it resets, and the bag continues to be output by the belt conveyor 3, entering the next cycle.

[0045] 5. Mobility and Redeployment

[0046] After the operation is completed, the support frame 15 is retracted, and the whole machine can be pushed to the warehouse or other production line without disassembling any parts, achieving "ready to use".
