Description

Technical Field

[0001] The utility model relates to the technical field of fin processing, in particular to an automatic anti-jamming device for a fin machine. Background Art

[0002] Fin production involves several steps, including punching, bulging, flanging, side cutting, and arc cutting. The number of fins used in a single unit varies depending on the product type, ranging from 200 to 900. To ensure continued production, fin production speed must be maximized.

[0003] To accommodate the processing and production speed of fins, the corresponding fin collection and drop speeds are also increased, resulting in a surge in the number of fins dropped per unit time. When the fin machine is operating, the production cycle of a single fin is fast, and the maximum distance between the fin drop point and the fin collection point is approximately 70cm. During the fin drop process, various minor factors can cause the fin to tilt during the drop, resulting in material jamming, making manual operation unavoidable during the collection process.

[0004] Therefore, there is still a need for an automatic anti-stuck device for a fin machine to solve the above problems. Utility Model Content

[0005] The utility model provides an automatic material-blocking prevention device for a fin machine, which solves the above-mentioned problem.

[0006] The purpose of this utility model is achieved by the following technical solutions:

[0007] An automatic anti-jamming device for a fin machine, comprising:

[0008] base;

[0009] A material receiving assembly, comprising a material receiving rod and a material guiding rod connected to the base, wherein the material guiding rod is located on both sides of the material receiving rod and is used to guide the falling materials to fall and be inserted on the material receiving rod;

[0010] The material shifting assembly includes a material shifting portion which is arranged adjacent to at least one side of the material receiving rod and is used to shift one end of the material sheet upward when the material sheet falls, so that the material sheet falls obliquely.

[0011] In one embodiment, the material-digging assembly further includes a support seat, a connecting rod and a rotating disk, wherein the connecting rod is connected to the base, the support seat is slidably connected to the connecting rod, the flexible material-digging portion is annularly arranged on the annular side wall of the rotating disk, and the axis of the rotating disk is rotatably connected to the base.

[0012] In one embodiment, the flexible material-diverting portion has a flexible surface for accommodating the falling material sheet, and when the material sheet contacts the flexible surface, the flexible surface is used to flexibly offset the impact of the material sheet and rotate to follow.

[0013] In one embodiment, the flexible surface is a rubber surface.

[0014] In one embodiment, there are two material receiving rods and two material guiding rods, and the two material receiving rods are vertically arranged side by side and located between the two material guiding rods.

[0015] In one embodiment, the bottom of the material receiving rod is also slidably connected to a material loading tray, and the top of the material loading tray is used to place the material sheets after being selected.

[0016] In one embodiment, a first sensor is connected to the base, and a second sensor is also accommodated in the material-diverting portion. During rotation, the first sensor and the second sensor cooperate to identify the number of falling sheets.

[0017] Compared with the prior art, the beneficial effects of the present invention include at least:

[0018] By installing a material-dividing assembly on one side of the receiving assembly on the base, which can directional cushion and support one end of the falling sheet, the material-dividing assembly briefly overlaps one end of the falling sheet during the falling process, so that multiple rapidly falling sheets are directional and tilted at a certain angle before being laid flat on the bottom and stacked in an orderly manner. This effectively prevents the free tilting of a large number of rapidly falling sheets, which can cause material jamming and abnormal stacking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0024] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0025] Reference Figure 1-3 The utility model provides an automatic anti-jamming device for a fin machine, comprising: a base 1, a material receiving assembly 2. The material receiving assembly 2 comprises a material receiving rod 21 and a material guide rod 22 connected to the base 1, the material guide rod 22 being located on both sides of the material receiving rod 21, for guiding the falling material to fall and be inserted on the material receiving rod 21. A material shifting assembly 3, the material shifting assembly 3 comprises a material shifting portion 31 arranged adjacent to at least one side of the material receiving rod 21, for shifting one end of the material 4 upward when the material 4 falls, so that the material 4 falls obliquely. The base 1 can be a flat substrate, or a base 1 composed of two slide rails, which is not limited here, wherein the material 4 has evenly distributed through holes, and when falling, the through holes of the material 4 pass through the material receiving rod 21. The material guide rod 22 guides the material 4 to fall on the peripheral side of the material receiving rod 21 by abutting against the edge of the material 4.

[0026] During operation, the falling sheet 4 will first pass through the material receiving rod 21 and be guided by the material guide rod 22, keeping one end of the sheet 4 in the length direction falling on the material picking portion 31, and then after being overlapped by the material picking portion 31, the other end of the sheet 4 sinks and finally falls to the bottom in an inclined posture, so that the falling sheets 4 are all picked in a uniform direction, avoiding the sheets 4 from falling randomly, causing the sheets 4 on the material receiving rod 21 to be stuck or even damaged.

[0027] Preferably, the material-digging assembly 3 further includes a support base 32 and a connecting rod 33. The connecting rod 33 is connected to the base 1, wherein the support base 32 can be a metal plate slidably connected to the connecting rod 33. The support base 32 is slidably connected to the connecting rod 33. The material-digging assembly 3 further includes a rotating disk 34. The material-digging portion 31 is annularly arranged on the annular sidewall of the rotating disk 34, and the axis of the rotating disk 34 is rotatably connected to the base 1. The rotating shaft of the rotating disk 34 is rotatably connected between the support bases 32, and the base of the material-digging portion 31 is connected to the annular sidewall of the rotating disk 34. There are multiple rotating disks 34 arranged in an annular array. When the sheet 4 falls, one end of the sheet 4 overlaps the top of the material-digging portion 31, driving the rotating disk 34 to rotate a certain angle. The rotating disk 34 moves a short distance with the end of the sheet 4, then rotates, and the sheet 4 then falls at an angle. This prevents the sheet 4 from falling directly and overlapping, which would cause excessive impact on the bottom end of the sheet 4 and cause deformation and damage. By providing the material-moving portion 31 that can rotate and move along with one end of the sheet 4 , the kinetic energy of the impact during the falling can be effectively avoided, and the deformation and damage of the sheet 4 can be avoided.

[0028] Preferably, the flexible material-dispensing portion 31 has a flexible surface for accommodating the falling material sheet 4. When the material sheet 4 contacts the flexible surface, it flexibly offsets the impact of the material sheet 4 and rotates to follow it. The flexible surface can be a rubber layer or silicone layer, or other flexible material, formed on the outer wall of the material-dispensing portion 31 through a lamination process. When contacting the bottom end of the material sheet 4, it can prevent direct damage to the bottom end of the material sheet 4 due to pile foundation, thereby maintaining a high pass rate for the material sheet 4 and production and material collection efficiency.

[0029] Preferably, the flexible surface is a rubber surface or a silicone surface.

[0030] Preferably, there are two receiving rods 21 and two guiding rods 22, and the two receiving rods 21 are arranged vertically side by side and located between the two guiding rods 22. Both receiving rods 21 are inserted into the holes of the sheet 4, and the two guiding rods 22 are located on both sides of the receiving rod 21, so as to prevent the sheet 4 from having a large angular deviation on the plane, which would cause the sheet to fall and be collected stably.

[0031] In one embodiment, a loading tray 23 is slidably connected to the bottom of the receiving rod 21. The top of the loading tray 23 is used to place the sheets 4 after the materials are selected. The loading tray 23 can slide on the bottom of the receiving rod 21. When the sheets 4 accumulate to a certain number, the stacked sheets 4 can be collected manually or using a push rod, which is convenient and quick.

[0032] In one embodiment, a first sensor is connected to the base 1, and a second sensor is housed within the material-dispensing portion 31. During rotation, the first and second sensors cooperate to identify the number of falling sheets 4. The first and second sensors can be two matching Hall effect devices. When their positions deviate from each other, the number of deviations is recorded, thereby recording the number of falling sheets 4.

[0033] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
