Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing consumable material jam identification devices, and in particular to a highly compatible linear consumable material break and jam identification device. Background Art

[0002] Traditional fused deposition modeling printing technology (FDM printing technology for short) has been widely used in education, medical treatment, design, manufacturing and other related technical fields in recent years due to its simple working principle, low production cost, simple maintenance, convenient operation and no pollution. At present, FDM printing technology has greatly shortened the product development and verification cycle, reduced production costs, and enabled enterprises to respond quickly to the ever-changing market.

[0003] However, FDM printing technology also has some shortcomings, among which the most important is the empty run of the printing equipment, that is, the printing equipment prints without material. The empty run of the printing equipment is mainly caused by the overlap, breakage or jamming of linear consumables. The main influencing factors are: 1. The quality of consumables. Linear consumables are made of cylindrical wires wound around the circumference of the material reel shaft. Due to the different processing quality of each manufacturer, the winding quality of the consumables is different. When printing with consumables with poor winding quality, the lower layer of wire will often press the upper layer of wire during the printing process, causing the consumables to become knotted or broken, resulting in failure of consumable extrusion and empty run of the printing equipment; in addition, linear consumables become brittle due to moisture, and sudden breakage of consumables during printing will also cause the equipment to empty run; 2. The quality of printing equipment accessories. The discharge nozzle and extruder gears of the printing equipment will produce wear, material accumulation, carbonization and other phenomena after long-term use, which will cause the discharge nozzle to fail to discharge material, resulting in empty run of the printing equipment.

[0004] At present, most of the consumable status identification devices on the market are still at the stage of material breakage identification. Most of them identify the consumable status by pressing the micro switch of the consumable. This method can only identify material breakage but not material jamming. Moreover, when the consumable is TPU soft consumable, the diameter of the consumable becomes thinner when stretched, causing the micro switch to pop up, which will cause misidentification, resulting in a decrease in the printing yield and an increase in the cost of printed products.

[0005] Therefore, how to design an identification device that can quickly, accurately and timely identify knots, breakages and jams in linear consumables is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0006] The utility model provides a highly compatible linear consumable material breakage and jam identification device, which has a breakthrough added jam identification function and has a compatibility design for coping with changes in consumable material diameter and soft consumable material adaptation. When the consumable material diameter fluctuates greatly, the device can still work normally, thereby improving the overall identification accuracy.

[0007] The utility model solves the above technical problems with the following technical solutions: a highly compatible linear consumable material break and jam identification device, comprising:

[0008] A shell, wherein the interior of the shell is hollow and two opposite sides thereof are respectively provided with a feed hole and a discharge hole; a conveying channel for linear consumables is provided between the feed hole and the discharge hole, and the linear consumables move along the axis of the conveying channel;

[0009] A code disc, the code disc is located at one side of the conveying channel and is rotatably connected to the inside of the shell, the rotation axis of the code disc is perpendicular to the axial direction of the conveying channel and its outer peripheral wall can contact the linear consumables that penetrate into the shell, so as to rotate along its axis with the movement of the linear consumables, and the disc surface of the code disc is provided with a plurality of through holes at intervals along its circumference,

[0010] An information collector is located on a side of the code disc away from the linear consumable and fixed on the inner side of the shell. A detection area is provided on a side of the information collector close to the code disc. The plurality of through holes rotate in or out of the detection area as the code disc rotates to determine the rotation speed of the code disc.

[0011] The beneficial effect of the utility model is: firstly, the linear consumable is used to drive the code disk to rotate, and then the information collector is used to count the number of through holes on the code disk passing through per unit time, so as to indirectly calculate the moving speed of the linear consumable. When the linear consumable is knotted, broken or stuck, its moving speed will also change accordingly. When the information collector can calculate the moving speed of the linear consumable in real time, it can also monitor in real time whether there is any abnormality in the linear consumable, thereby preventing the printing equipment from running empty in advance, improving the yield of printed products, and reducing the production cost of printed products.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the information collector includes:

[0014] A circuit board, the circuit board is located on a side of the code disc away from the conveying passage and is fixed on an inner side wall of the housing;

[0015] A photoelectric transmitter and a photoelectric receiver are electrically connected to the circuit board, wherein the photoelectric transmitter and the photoelectric receiver are respectively placed above and below the through hole and are fixed on a side of the circuit board close to the code disk, and the detection area is the gap between the photoelectric transmitter and the photoelectric receiver.

[0016] A further beneficial effect of the above method is that the light emitted by the photoelectric transmitter can be received by the photoelectric receiver only when the through hole on the code disk is between the photoelectric transmitter and the photoelectric receiver, so that the code disk rotates. The photoelectric transmitter and the photoelectric receiver can count the number of through holes passing through the detection area, thereby calculating the rotation speed of the code disk.

[0017] Furthermore, it also includes a pushing component for pushing the code disc close to the linear consumable, and the pushing component includes:

[0018] A first push rod and a second push rod are located inside the shell, wherein the first push rod is placed parallel to one side of the conveying passage and one end of the first push rod is rotatably connected to the inner bottom surface of the shell, and the rotation axis of the first push rod is perpendicular to the axis direction of the conveying passage; one end of the second push rod is vertically fixed to the side wall of the first push rod away from the conveying passage;

[0019] A coupling seat, the coupling seat is rotatably connected to the other end of the first push rod through a bearing and its rotation axis is parallel to the rotation axis of the first push rod; the code disc is fixed on the coupling seat;

[0020] a fixed column, the fixed column being separated from the first push rod by a predetermined distance and fixed to the inner bottom surface of the housing;

[0021] An elastic pull rope, one end of which is tied to the other end of the second push rod and the other end of which is tied to the fixed column, so as to elastically push the code disc close to the linear consumable.

[0022] A further beneficial effect of the above method is that by using an elastic pull rope to pull the second push rod to rotate, the code disk can be pushed in the opposite direction to be close to the linear consumables, thereby adapting to the identification of linear consumables of different hardness and thickness, increasing the friction between the code disk and the linear consumables of different hardness and thickness, and improving the compatibility and recognition accuracy of the recognition device.

[0023] Furthermore, a groove is provided on the side wall of the second push rod opposite to and away from the fixing column; one end of the elastic pull rope is tied in the groove.

[0024] A further beneficial effect of the above method is that by tying the elastic drawstring in the groove, the stability of the elastic drawstring tied to the push rod can be improved.

[0025] Furthermore, it also includes a guide tube, which is located at the conveying channel inside the shell and has an inlet end fixed and connected to the feed hole. The guide tube is a predetermined distance away from the discharge hole; the linear consumable slides through the guide tube.

[0026] A further beneficial effect of the above method is that by fixing the guide tube in the shell, the conveying direction of the linear consumables can be guided to prevent the linear consumables from being offset during transportation.

[0027] Furthermore, the cross section of the through hole is rectangular, the length is 3mm-5mm, and the width is 1mm-2mm.

[0028] Furthermore, the diameters of the feed hole and the discharge hole are both 30 mm-90 mm. BRIEF DESCRIPTION OF THE DRAWINGS
