Therefore, they cannot be understood as limitations on the present invention.

[0027] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0028] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] Reference Figures 1 to 3 The utility model is a strip counting and packaging device, comprising: a frame 100, on which a rotary driver 200 and a discharge rod 300 connected to the output end of the rotary driver 200 are provided; at least two trough members 400, which are circumferentially distributed around the axis of the discharge rod 300 at intervals, and the trough members 400 are extended along the length direction of the discharge rod 300, and the trough members 400 have an inlet and outlet radially away from the discharge rod 300; a material receiving bin 500, which is located below the discharge rod 300. The material receiving bin 500 has a material receiving channel that runs through in the vertical direction, the upper end of the material receiving channel is connected to the unloading rod 300, and the lower end of the material receiving channel is provided with a first switch mechanism 510 for isolating or opening it; the sensor 600 is used to record the number of products input into the material receiving bin 500; the control module is electrically connected to the sensor 600, the rotary driver 200 and the first switch mechanism 510, and is used to control the start and stop of the rotary driver 200 and the opening and closing of the first switch mechanism 510.

[0030] The products in the strips fall one by one from above the discharge rod 300 to enter one of the trough parts 400. The rotary driver 200 drives the discharge rod 300 to rotate so that the inlet and outlet of the trough part 400 containing the product faces downward to release the product. The product falls into the receiving bin 500 under the action of its own gravity. At the same time, the inlet and outlet of one of the empty trough parts 400 is vertically upward to receive another product. The sensor 600 records the number of products input into the receiving bin 500. When the number reaches the preset value, the first switch mechanism 510 is turned on to release the products in the receiving bin 500 to the next process for packaging. The above structure is used to realize the function of collecting the products of the strips in a certain quantity and then conveying them to the packaging process, thereby improving production efficiency and ensuring that the strips are neatly packaged together.

[0031] See also Figure 1 and Figure 2In some embodiments of the present invention, the three trough members 400 are evenly spaced about the axis of the discharge rod 300. The frame 100 is provided with a guide baffle 700 located on one side of the predetermined rotational direction of the discharge rod 300. The guide baffle 700 is arranged parallel to the discharge rod 300, and the length of the guide baffle 700 matches the length of the trough member 400. It is understood that when there are three trough members 400, the discharge rod 300 only needs to rotate 120° to move to another empty trough member 400 to receive the product. At this time, the product to be released is tilted 60° relative to the vertical direction. The product can slide downward along the inlet and outlet of the trough member 400. The guide baffle 700 can block the product and guide it downward, thereby improving counting efficiency and thus improving packaging efficiency.

[0032] See also Figure 1 and Figure 2 In some embodiments of the present invention, the frame 100 is provided with an elongated through hole 110 opposite to the upper end of the material receiving channel. When the discharge rod 300 rotates 120° in a preset rotation direction, the inlet and outlet of one of the trough members 400 faces the guide baffle 700 to guide the product to fall downward and pass through the elongated through hole 110. The sensor 600 is a grating assembly provided on both sides of the width direction of the elongated through hole 110. It can be understood that the elongated through hole 110 is adapted to the length of the product, which can reduce the probability of the product being twisted or tangled. When the product passes downward through the elongated through hole 110, the grating assembly records that a product has entered the material receiving bin 500, and the counting accuracy is high. When the recorded number of products reaches a preset value, the control module can control the rotary driver 200 to temporarily stop rotating, and then the first switch mechanism 510 opens the lower end of the material receiving channel.

[0033] See also Figure 1 and Figure 2 In some embodiments of the present invention, in order to accommodate the counting and conveying of strip-shaped products of different lengths, the discharge rod 300 can be detachably connected to the output end of the rotary driver 200 , and the guide baffle 700 can be detachably mounted on the frame 100 .

[0034] See also Figure 2In some embodiments of the present invention, in order to realize convenient disassembly and installation of the unloading rod 300, the rotary driver 200 is a first motor, and the unloading rod 300 includes a sleeve 310 sleeved on the outside of the output shaft of the first motor, and the side of the sleeve 310 is penetrated by a fastening screw that is tightened to the output shaft of the first motor. In order to facilitate the production and assembly of the trough part 400, the end of the sleeve 310 is provided with a flange part 320, and the flange part 320 is provided with a plurality of groups of socket groups 321 corresponding to the trough part 400 at intervals around the circumference of the output shaft of the first motor. One end of the trough part 400 is provided with a plug-in protrusion 410 corresponding to the socket group 321, and the other ends of all the trough parts 400 are connected together by a positioning plate 330.

[0035] See also Figure 2 In some embodiments of the present invention, the cross-section of the trough member 400 is a trapezoidal shape with its opening gradually widening away from the discharge rod 300. The positioning plate 330 is provided with trapezoidal grooves 331 spaced around the circumference of the output shaft of the first motor, which mate with the outer circumferential wall of the trough member 400. The trapezoidal grooves 331 and the trough member 400, as well as the insertion protrusions 410 and the socket group 321, are welded together. It will be appreciated that the shape of the trough member 400 not only facilitates the entry and exit of products into and out of the trough member 400 but also facilitates the positioning plate 330 in accurately positioning and securing the three trough members 400. Of course, in some embodiments, welding between the insertion protrusions 410 and the socket group 321 is unnecessary; instead, the positioning plate 330 and the trough member 400, facing away from the flange member 320, can be screwed together, allowing the trough member 400 to be replaced individually.

[0036] See also Figure 1In some embodiments of the present invention, the frame 100 is provided with at least one temporary storage bin 800 below the receiving bin 500 for storing a set number of products. The lower opening of the temporary storage bin 800 is connected to the insertion end of the packaging bag on the packaging machine, and a second opening mechanism 810 is provided at the lower opening of the temporary storage bin 800. It should be noted that when the number of products in the receiving bin 500 reaches the set number, if the first opening mechanism 510 opens late or the rotary driver 200 fails to stop, the product count may be inaccurate. In addition, the packaging machine needs to wait until the number of products in the receiving bin 500 reaches the set number before it can start packaging, which seriously affects packaging efficiency. When the above technical solution is adopted, the first switch mechanism 510 is in a normally open state, and products dropped into the receiving hopper 500 are directly transferred to the temporary storage hopper 800. When the number of products in the temporary storage hopper 800 reaches a set number, the first switch mechanism 510 is closed, and the second switch mechanism 810 is opened to input the products into the packaging machine. When the second switch mechanism 810 is closed again, the first switch mechanism 510 is opened again, thereby improving packaging efficiency. It is understood that in order to avoid waiting for packaging, multiple temporary storage hoppers 800 can be provided.

[0037] See also Figure 4 In some embodiments of the present invention, the discharge rod 300, the receiving bin 500, and the temporary storage bin 800 are arranged in a row to form a discharge assembly. The frame 100 is arranged with an even number of the discharge assemblies spaced apart along a certain horizontal direction. Adjacent discharge assemblies form an output assembly unit in pairs. Each output assembly unit is provided with a collecting hopper 900 below. The collecting hopper 900 is used to merge the products output from the two temporary storage bins 800 at the lower end of the same output assembly unit. The total number of products output from the two temporary storage bins 800 at the lower end is consistent with a preset number. It is understood that in automated production, a conveyor belt is generally used to transport products to the top of the discharge rod 300. Different discharge rods 300 receive different quantities of products. When a discharge rod 300 is continuously low, in order to avoid the discharge assembly being unable to collect the required number of products for a single packaging bag for a long time, the above combination method can improve the production efficiency of counting packaging.

[0038] See also Figure 1 and Figure 3In some embodiments of the present invention, when changing the packaged products on the production line, a hanger 120 is detachably mounted on the frame 100 to facilitate quick cleaning of the receiving bin 500 and the temporary storage bin 800. The receiving bin 500 and the corresponding temporary storage bin 800 are vertically spaced apart on the hanger 120. Specifically, the frame 100 is provided with two I-shaped hanging posts 130, and the hanger 120 has two hanging slots 122 corresponding to the two hanging posts 130. Under the action of gravity of the receiving bin 500 and the temporary storage bin 800, the hanger 120 stably connects the hanging slots 122 to the hanging posts 130. In addition, when the bracket 120 is mounted on the frame 100, the rotation of the eccentric wheel driven by the motor can control the opening and closing of the first switch mechanism 510 and the second switch mechanism 810. The structures of the first switch mechanism 510, the second switch mechanism 810, the material receiving bin 500 and the temporary storage bin 800 are consistent with the existing technology and will not be further elaborated here.

[0039] See also Figure 3 In some embodiments of the present invention, the hanging bracket 120 includes a vertical beam 121 arranged in a vertical direction. The receiving bin 500 and the temporary storage bin 800 are both provided with a mounting plate 820 that can be abutted against the side wall of the vertical beam 121. The mounting plate 820 is provided with waist-shaped holes arranged in a vertical direction. The vertical beam 121 is provided with a plurality of mounting through holes corresponding to the waist-shaped holes. Bolt assemblies are passed through the waist-shaped holes and the mounting through holes to fix the mounting plate 820 to the vertical beam 121. It is understandable that the height positions of the receiving bin 500 and the temporary storage bin 800 can be adjusted according to the length of the product, thereby achieving adaptive production.

[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
