A material conveying mechanism with dual servo regulation

Abstract

This utility model belongs to the field of packaging technology, specifically relating to a dual-servo adjustable material conveying mechanism for adjusting the width of material bins on a material conveyor belt. It consists of a material conveyor belt and a servo transmission mechanism. The key feature is that the material conveyor belt comprises an inner conveyor belt a and an outer conveyor belt b. Conveyor belt a has a bin plate a, which, along with the bin plate b on conveyor belt b, forms a material bin of the same width. The servo transmission mechanism consists of servo motors a and b, which respectively control drive pulleys a and b. When the material width data is input into the human-machine interface, a one-key adjustment is clicked. At this time, drive pulley a controls the inner conveyor belt a to be fixed, while drive pulley b controls the outer conveyor belt b to be adjusted. After the material bin width adjustment is set, a one-key lock is clicked, thus forming a dual-servo adjustable material conveying mechanism. Its beneficial effect is that the mechanism, with dual servo motors adjusting and controlling the material bin width, can adapt to the feeding and conveying of materials of different widths.

Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically relating to a dual-servo adjustable material conveying mechanism for adjusting the width of the material bin on the material conveyor belt of a cartoning machine. Background Technology

[0002] Currently, the material conveying mechanisms on existing cartoning machines use conveyor belts with fixed material bin widths, meaning the width of the material bins used for conveying materials is fixed and cannot be adjusted arbitrarily. Another type uses conveyor belts with adjustable material bin widths, but these are manually adjustable. As is well known, manual adjustment is difficult to achieve precisely; not only is the adjustment accuracy insufficient, but it is also time-consuming. If the adjustment is not precise enough, repeated fine-tuning is required to achieve relative accuracy. Clearly, this type of cartoning production line is not intelligent enough; the adjustment process not only delays the manufacturer's production time but also reduces the efficiency of the cartoning equipment.

[0003] To address the issue of adjustable material hoppers on material conveyor belts, and to accommodate materials of varying widths, we urgently need an innovative design. This design allows for rapid and precise automatic adjustment of the material hopper width by inputting material width data into the control system's human-machine interface and clicking a single button. Essentially, this is a dual-servo adjustable material conveying mechanism capable of handling materials of different widths. Summary of the Invention

[0004] To solve the problem of adjusting the material hopper on the material conveyor belt, to adapt to the feeding and conveying of materials of different widths, and to work with the rear mechanism of the cartoning machine to complete the purpose of feeding and cartoning, this patent has specially designed an innovative material conveying mechanism with dual servo adjustment that can adapt to the feeding and conveying of materials of different widths.

[0005] To achieve the above objectives, the concept of this utility model is as follows: To address the issue of adjusting the width of material bins on conveyor belts, we have innovatively designed a material conveyor belt consisting of inner and outer conveyor belts (a and b). A drive wheel assembly is located at the front end of each conveyor belt, driven by dual servo motors individually or as a whole. This drives the movement of conveyor belts a and b, either individually or as a whole. Bin plates a and b are installed on conveyor belts a and b, respectively, forming a standard material bin. When one of the servo motors controls the adjustment of the outer conveyor belt b, the inner conveyor belt a remains stationary. This allows the material bin formed by the bin plate a on the inner conveyor belt a and the bin plate b on the outer conveyor belt b to automatically adjust its width. By inputting the required width of the material to be conveyed into the human-machine interface of the control system, the width of the material bin on the conveyor belt can be adjusted accordingly, thus accommodating the feeding and conveying of materials of various widths.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows: A dual-servo adjustable material conveying mechanism, used for adjusting the width of the material bin on the material conveyor belt, comprises a material conveyor belt and a servo drive mechanism, characterized in that: The material conveyor belt consists of an inner conveyor belt a and an outer conveyor belt b. The conveyor belt a is provided with a bin plate a, which is staggered with the bin plate b provided on the conveyor belt b to form a material bin of the same width. The servo transmission mechanism consists of servo motor a and servo motor b controlling transmission pulley a and transmission pulley b respectively. When inputting the width data of the conveyed material on the human-machine interface, click one-key adjustment. At this time, the transmission pulley a controls the inner conveyor belt a to be fixed, and the transmission pulley b controls the outer conveyor belt b to be adjusted. Once the width of the material hopper is adjusted and set, clicking the one-click lock button will create a material conveying mechanism with dual servo adjustment.

[0007] Preferably, the material conveyor belt has a drive wheel assembly at the front end and a driven wheel assembly at the rear end. The drive wheel assembly consists of a solid shaft with drive wheel a and a hollow shaft with drive wheel b. When the servo motor a and servo motor b work synchronously, they drive the drive wheel assembly at the front end of the material conveyor belt, thereby driving the driven wheel assembly at the rear end to move forward as a whole.

[0008] Preferably, the servo motor b drives the transmission pulley b, which in turn drives the hollow shaft to drive the outer conveyor belt b, causing the position of the silo plate b on the conveyor belt b to move. At this time, the position of the silo plate a on the conveyor belt a is fixed. As the position of the silo plate b moves, the distance between the silo plate a and the silo plate b, i.e., the width of the material silo, is automatically adjusted.

[0009] Preferably, the servo motor a drives the transmission pulley a, the transmission pulley a drives the transition shaft, and the other end of the transition shaft is fitted with a transition synchronous pulley. The transition shaft, the transition synchronous pulley, and the solid shaft are interconnected and driven by each other. The transition shaft drives the transition synchronous pulley to drive the solid shaft, and the drive wheel a on the solid shaft drives the conveyor belt a to move.

[0010] The above-mentioned scheme further includes: Preferably, the material conveying mechanism with dual servo adjustment is characterized in that: tensioning wheels are also provided on the inner sides of the transmission pulleys a and b for adjusting the tension of the transmission pulleys a and b.

[0011] The above plan further includes: Preferably, the material conveying mechanism with dual servo adjustment is characterized in that: the material bin on the material conveyor belt can be used for feeding and conveying materials of different widths, and the width of the material bin can be freely adjusted within the range of 20 to 200 mm.

[0012] This patent describes a dual-servo adjustable material conveying mechanism, employing a transmission structure driven and controlled by dual servo motors. By controlling and adjusting the outer conveyor belt, the width of the material bin formed by the bins on the inner and outer conveyor belts is adjusted accordingly. Based on the actual required material width, the corresponding material bin width can be input on the human-machine interface of the control system to convey materials of various widths.

[0013] Compared with the prior art, this utility model has the following obvious substantive features and advantages: 1. This material conveying mechanism is controlled by dual servo motors, which adjust the width of the material bin on the conveyor belt according to the maximum width of the material being conveyed, making it suitable for conveying materials of various widths.

[0014] 2. This material conveying mechanism is particularly suitable for conveying materials with special shapes. The width and depth of the material bins on the material conveyor belt can adapt to the safe feeding and stable conveying of various materials.

[0015] Its beneficial effects are: The mechanism uses dual servo motors to adjust and control the width of the material bin, which can adapt to the feeding and conveying of materials of different widths. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings: A dual-servo adjustable material conveying mechanism, used for adjusting the width of the material bin on the material conveyor belt, comprises a material conveyor belt 1 and a servo transmission mechanism 2, characterized in that: The material conveyor belt 1 is composed of an inner conveyor belt a3 and an outer conveyor belt b4. The conveyor belt a3 is provided with a bin plate a5, which is staggered with the bin plate b6 provided on the conveyor belt b4 to form a material bin of the same width. The servo transmission mechanism 2 is composed of servo motor a8 and servo motor b9 controlling transmission pulley a10 and transmission pulley b11 respectively. When inputting the width data of the conveyed material on the human-machine interface, click one-key adjustment. At this time, the transmission pulley a10 controls the inner conveyor belt a3 to be fixed, and the transmission pulley b11 controls the outer conveyor belt b4 to be adjusted. Once the material bin width is adjusted and set, clicking the one-click lock button will create a dual-servo adjustable material conveying mechanism. (See attached image) Figure 1 As shown.

[0018] A material conveying mechanism with dual servo adjustment, characterized by the following technical structure: Preferably, the material conveyor belt 1 has a drive wheel assembly 17 at its front end and a driven wheel assembly 18 at its rear end. The drive wheel assembly 17 consists of a solid shaft 15 with a drive wheel a19 and a hollow shaft 16 with a drive wheel b20. When the servo motors a8 and b9 operate synchronously, they drive the drive wheel assembly 17 at the front end of the material conveyor belt 1, thereby causing the driven wheel assembly 18 at the rear end to move forward as a whole. (See attached diagram) Figure 4 , 5 As shown in Figure 6.

[0019] Preferably, the servo motor b9 drives the transmission pulley b11, which in turn drives the hollow shaft 16 to drive the outer conveyor belt b4, causing the position of the silo plate b6 on the conveyor belt b4 to move. At this time, the position of the silo plate a5 on the conveyor belt a3 is fixed. As the position of the silo plate b6 moves, the distance between the silo plate a5 and the silo plate b6, i.e., the width of the material silo, is automatically adjusted. (See attached diagram) Figure 2 , 3 As shown in Figures 4, 5, and 7.

[0020] Preferably, the servo motor a8 drives the transmission pulley a10, which in turn drives the transition shaft 12. A transition synchronous pulley 13 is sleeved at the other end of the transition shaft 12. The transition shaft 12, the transition synchronous pulley 13, and the solid shaft 15 are interconnected. The transition shaft 12 drives the transition synchronous pulley 13 to the solid shaft 15, and the drive wheel a19 on the solid shaft 15 drives the conveyor belt a3. (See attached diagram) Figure 2 , 4 As shown in 5, 6, and 7.

[0021] Preferably, the material conveying mechanism with dual servo adjustment is characterized in that: a tensioning wheel 14 is further provided inside the transmission pulleys a and b for adjusting the tension of the transmission pulleys a and b. (See attached diagram) Figure 5 As shown.

[0023] Once the width of the material hopper is locked, the material conveyor belt 1, via the drive wheel set 17 at the front end, drives the driven wheel set 18 at the rear end to move as a whole. The servo motors a8 and b9 are then activated synchronously, driving the drive wheel set 17 at the front end of the material conveyor belt 1 to move the driven wheel set 18 forward, thus achieving the purpose of adapting to the conveying of materials of various widths.

[0024] The material conveying mechanism described in this patent, which is a dual-servo adjustable mechanism, can be used for feeding and conveying materials of various widths. The width of the material bin on the conveyor belt can be adjusted according to the maximum width of the conveyed material. In actual non-standard cartoning equipment, the material bin on the conveyor belt can be freely adjusted within the range of 30 to 170 mm.

Any equivalent variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this invention should be included within the scope of protection of this invention.
