Description

Technical Field

[0001] The utility model relates to the technical field of production measurement of injection molded covers, in particular to automatic counting equipment for production of injection molded covers with spoons. Background Art

[0002] The injection molded lid with a spoon is a common plastic packaging lid, usually used for beverage bottles or other liquid containers. It is characterized by a small spoon attached to the lid, which is convenient for users to take powdered or granular items such as coffee, milk powder or pharmaceutical products when using it. This kind of lid needs to be accurately counted during the production process to ensure that the number of lids in each packaging unit is accurate. The counting equipment is used in the production process of the injection molded lid with a spoon, which is mainly composed of a feeding device, a counting area, a conveying system and a control system. The injection molded lid with a spoon enters the equipment through a vibrating plate or a conveyor belt. After entering the counting area, the built-in sensor (such as a photoelectric or laser sensor) will detect the passage of each lid. The sensor signal is processed by the control system and recorded by the counter. After the counting is completed, the lid moves to the next production stage or packaging equipment through the conveying system to ensure the accurate number of lids in each packaging unit;

[0003] For example, an automatic counting device for producing injection molded covers with spoons disclosed in the authorization announcement number CN213783278U includes a bottom plate, a fast counting component, a displacement push plate component, a sorting and dropping component and a material receiving box. A support leg is fixedly connected to the bottom of the bottom plate, a fast counting component is installed on the upper right side of the bottom plate, a pillar is fixedly connected to the upper left side of the bottom plate, a displacement push plate component is installed in the middle of the pillar, a sorting and dropping component is fixedly connected above the pillar, a discharge port is provided in the middle of the left side of the sorting and dropping component, a discharge port is fixedly connected to the lower right side of the sorting and dropping component, and the bottom plate is fixedly connected to the bottom plate. A material receiving box is provided on the right side of the plate, and the pressure of the No. 1 spring rod is adjusted by a dial wheel, a nut, and a screw rod, so that it is easy to adjust according to the weight of the finished product to avoid counting errors, and the finished product counting work can be conveniently and effectively performed. However, in this technical solution, the finished product falls on the upper plate, presses the upper plate downward to touch the counting switch, and completes one count. However, some injection-molded covers with spoons are made of transparent material and are light in weight. Their own weight may not be able to overcome the gravity of the spring and touch the counting switch, making it difficult for the sensor to accurately identify the position and existence of the cover, resulting in missed touches and missed detections.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6 The utility model provides an embodiment: an automatic counting device for producing injection molded covers with spoons, comprising a conveyor frame 1 and a double-belt-wheel feeding structure 2 for transferring injection molded covers with spoons arranged inside the conveyor frame 1, a right-angle frame 3 is fixed to one side of the bottom end of the conveyor frame 1, and a belt wheel driving unit 4 for driving the double-belt-wheel feeding structure 2 to work is installed on the outer wall of one side of the right-angle frame 3;

[0021] A right-angle seat 5 is installed on both sides of the top of the conveying frame 1, and a convex seat 6 is fixed on the top of the right-angle seat 5, an infrared counting sensor probe 8 is installed on the back of one of the convex seats 6 through a support, an axle frame 9 is fixed on the outer wall of one side of the convex seat 6, and a swing arm 10 is hinged inside the axle frame 9, a longitudinal beam 11 is installed between the two swing arms 10, and a baffle plate 12 inclined toward the right-angle frame 3 is provided at the bottom end of the longitudinal beam 11, and an elastic self-resetting shielding structure 13 is provided inside the convex seat 6;

[0022] In order to ensure that there is a certain distance between each injection-molded cover with a spoon, the staff can also set a cylinder and a baffle at the feeding port of the double-belt-wheel feeding structure 2. Through the extension and retraction of the cylinder and the baffle, there is a certain distance between adjacent injection-molded covers with a spoon to ensure the subsequent detection accuracy;

[0023] The pulley drive unit 4 includes a servo motor installed on the outer wall of one side of the right-angle frame 3, and a belt transmission structure installed at the output end of the servo motor for driving the double-pull feeding structure 2 to work. By adjusting the rotation speed of the pulley drive unit 4 and the double-pull feeding structure 2, the conveying speed of the injection-molded cover with a spoon can be accurately controlled to meet different production requirements and the working efficiency of the counting equipment;

[0024] The support member is a U-shaped bracket 7 fixed to the back of one of the convex seats 6, and the infrared counting sensor probe 8 is installed inside the U-shaped bracket 7;

[0025] The baffle plate 12, the longitudinal beam 11, and the swing arm 10 are all made of hard plastic. Compared with metal materials, hard plastic is usually lighter, so that the cover body can relatively easily trigger the baffle plate 12 to swing.

[0026] A semicircular protrusion for contacting the movable end of the elastic self-resetting shielding structure 13 is installed on the outer wall of the side of the swing arm 10 close to the convex character seat 6. The elastic self-resetting shielding structure 13 includes a slide rod 1301 slidably installed inside the convex character seat 6. One end of the slide rod 1301 penetrates the outside of the convex character seat 6 and is installed with an end cap 1302. The other end of the slide rod 1301 is fixed with a ejector pin 1304, and the end of the ejector pin 1304 close to the infrared counting sensor probe 8 is fixed with a baffle 1305. A reset spring 1303 is installed on one side of the convex character seat 6. One end of the reset spring 1303 abuts against the other end of the slide rod 1301. When the injection molded cover with a spoon is connected to the baffle plate 12, the ejector pin 1304 is fixed with a baffle plate 1305. When touched, the swing arm 10 creates a thrust force on the end cap 1302, and the end cap 1302 drives the slide bar 1301, the ejector pin 1304, and the baffle 1305 to translate until the baffle 1305 blocks the end of the infrared counting sensor probe 8. When the injection-molded cover with a spoon passes through the baffle plate 12, the reset spring 1303 forces the slide bar 1301, the ejector pin 1304 and other components to reset, so that when each injection-molded cover with a spoon passes through the counting area, the elastic self-resetting shielding structure 13 can ensure that the sensor probe is stably blocked once, thereby eliminating the counting error that may be caused by transparent materials or light weight, and can maintain efficient and stable counting performance during long-term production operations.

[0027] When the embodiment of the present application is in use, first, the staff will place the spoon-molded cover materials to be counted and processed in the conveying frame 1, and the belt wheel driving unit 4 drives the double-belt wheel feeding structure 2 to work, so that the double-belt wheel feeding structure 2 conveys the spoon-molded covers one by one. When the spoon-molded cover is conveyed between the two right-angle seats 5 and keeps moving forward, the spoon-molded cover will contact the baffle plate 12 under the movement of the double-belt wheel feeding structure 2, and as the spoon-molded cover moves, the spoon-molded cover will force the baffle plate 12, the longitudinal beam 11, and the swing arm 10 to swing around the shaft frame 9 as the center of the circle, that is, the swing arm 10 swings toward the direction of the convex seat 6 and squeezes the elastic self-resetting shielding structure 13, then the movable end of the elastic self-resetting shielding structure 13 blocks the infrared counting sensor probe 8 once, and when the spoon-molded cover completely passes through the baffle plate 12, the elastic self-resetting shielding structure 13 Resetting does not block the infrared counting sensor probe 8, thereby completing a counting action. At this time, the device waits for the arrival of the next injection molded cover with a spoon and performs the counting operation of the injection molded cover with a spoon according to the same steps. During the operation of the equipment, the pulley drive unit 4 and the double-pulley feeding structure 2 can stably transport the injection molded cover with a spoon from the feed end to the counting area, ensuring that the cover will not be stuck or leaked during the transportation process, and the elastic self-resetting shielding structure 13 can stably block the infrared counting sensor probe 8 when the injection molded cover with a spoon passes through. This structural design can ensure that each time the injection molded cover with a spoon passes, the sensor can accurately detect the blocking signal, thereby completing an accurate count. Regardless of whether the injection molded cover with a spoon is transparent, light in weight or irregular in shape, the elastic self-resetting shielding structure can maintain stable operation to avoid missed detection or false detection problems caused by the characteristics of the cover.
