Description

Technical Field

[0001] This utility model belongs to the field of chain braiding counting technology, and in particular relates to a chain continuous forming braiding counting device. Background Technology

[0002] A chain is composed of multiple links (links) connected together. Each link is connected by a pin and a shaft hole, and it is mainly used in industrial equipment for mechanical transmission, lifting, traction, and other applications. The number of links, length, and strength of a chain directly affect its working performance.

[0003] During chain production, it is impossible to accurately count the number of chain links, resulting in the production of chains with too many or too few links. After counting, the corresponding number of links needs to be added or excess links need to be cut, which increases the difficulty of chain production. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A chain continuous forming chain counting device includes a suspension frame, a chain take-up mechanism, and an infrared counter. The chain take-up mechanism and the infrared counter are both mounted on the cross arm of the suspension frame. The chain take-up mechanism includes a rotating shaft. A chain take-up roller and a baffle are fixedly sleeved on the outer ring of the rotating shaft. The chain take-up roller is threadedly connected to several cantilever shafts. A sliding sleeve is movably sleeved on the cantilever shaft. A reflector plate is fixedly connected to the outer wall of the sliding sleeve. A spring is provided between the sliding sleeve and the chain take-up roller. The end of the reflector plate away from the sliding sleeve extends to the emitter side of the infrared counter.

[0006] As a preferred embodiment of the above technical solution, the two baffles are located at both ends of the take-up roller, and the baffles are provided with a number of sliding openings, and the reflector is slidably connected to the sliding openings.

[0007] As a preferred embodiment of the above technical solution, the cross arm of the suspension frame is fixedly connected to a first bracket and a second bracket, the first bracket is rotatably connected to a grooved wheel, and the rotating shaft is rotatably connected to the second bracket.

[0008] As a preferred embodiment of the above technical solution, the cross arm of the suspension frame is fixedly equipped with a drive mechanism, and the drive mechanism is connected to the rotating shaft for transmission.

[0009] As a preferred embodiment of the above technical solution, the drive mechanism includes a motor fixed on the cross arm of the suspension frame, a drive wheel fixedly connected to the output end of the motor, a sprocket fixedly connected to one end of the rotating shaft, and a transmission chain connecting the sprocket and the drive wheel.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. When the rotating shaft drives the take-up roller to rotate, the cantilever shaft is inserted into the hole of the chain link to drive the chain to move. The sliding sleeve and reflector at the top will move to the side closer to the take-up roller due to the weight of the chain. At this time, the infrared signal emitted by the infrared counter will be blocked and reflected. When the baffle drives the reflector away, one count will be completed.

[0012] 2. Since there is a chain link left between two adjacent cantilever shafts, the final count needs to be multiplied by two to obtain the final quantity, thereby improving the accuracy of counting, avoiding the situation of too many or too few chain links, and reducing the processing difficulty.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 and Figure 2 As shown, the chain continuous forming chain counting device includes a suspension frame 10, a chain take-up mechanism 20, and an infrared counter. The chain take-up mechanism 20 and the infrared counter are both mounted on the cross arm of the suspension frame 10. The chain take-up mechanism 20 includes a rotating shaft 21. The outer ring of the rotating shaft 21 is fixedly fitted with a chain take-up roller 23 and a baffle 24. The chain take-up roller 23 is threadedly connected to several cantilever shafts 25. The cantilever shafts 25 are movably fitted with sliding sleeves 26. The outer wall of the sliding sleeve 26 is fixedly connected with a reflector 28, and a spring 27 is provided between the sliding sleeve 26 and the chain take-up roller 23. The end of the reflector 28 away from the sliding sleeve 26 extends to the emitter side of the infrared counter.

[0020] It should be noted that the number and thickness of the cantilever shafts 25 can be set according to the size of the chain; the larger the chain, the fewer the number of cantilever shafts 25.

[0021] Specifically, when the rotating shaft 21 drives the take-up roller 23 to rotate, the cantilever shaft 25 inserts into the hole of the chain link and drives the chain to move. The top sliding sleeve 26 and reflector 28 will move closer to the take-up roller 23 due to the weight of the chain. At this time, the infrared signal emitted by the infrared counter will be blocked and reflected. When the baffle 24 drives the reflector 28 away, one count is completed. Since there will be a chain link between two adjacent cantilever shafts 25, the final count needs to be multiplied by two to get the final number, thereby improving the accuracy of the count, avoiding the situation of too many or too few chain links, and reducing the processing difficulty. When the reflector 28 is without a chain, the spring 27 pushes the reflector 28 away from the take-up roller 23. In this way, when the take-up roller 23 is idling, the infrared counter cannot count.

[0022] like Figure 1 As shown, the cross arm of the suspension bracket 10 is fixedly connected to bracket 11 and bracket 2 13. Bracket 11 is rotatably connected to grooved wheel 12, and rotating shaft 21 is rotatably connected to bracket 2 13.

[0023] Specifically, the grooved wheel 12 provides auxiliary guidance for the chain, ensuring that the chain is flat overall.

[0024] like Figure 1 As shown, the cross arm of the suspension bracket 10 is fixedly equipped with a drive mechanism 30, which is connected to the rotating shaft 21 for transmission.

[0025] It should be noted that the drive mechanism 30 includes a motor fixed on the cross arm of the suspension frame 10, the output end of the motor is fixedly connected to a drive wheel, one end of the rotating shaft 21 is fixedly connected to a sprocket 22, and the sprocket 22 is connected to the drive wheel by a transmission chain.

[0026] Specifically, the motor drives the rotating shaft 21 to rotate on the bracket 13 through the drive wheel, transmission chain and sprocket 22, thereby driving the chain to move and count.

[0027] like Figure 2 As shown, two baffles 24 are located at the two ends of the take-up roller 23, and the baffles 24 have several sliding openings 241, with the reflector 28 slidably connected to the sliding openings 241.

[0028] Specifically, the sliding fit between the reflector 28 and the sliding opening 241 allows the sliding sleeve 26 to slide only on the outer ring of the cantilever shaft 25 without rotating. At the same time, the number of sliding openings 241 on a baffle 24 is the same as the number of cantilever shafts 25.

[0029] The working principle of an infrared counter is as follows:

[0030] 1. The transmitter emits infrared light: The transmitter in the infrared counter continuously emits infrared signals.

[0031] 2. Receiver receives infrared light: Infrared signals are reflected or blocked by objects and then received by the receiver.

[0032] 3. Signal conversion: The receiver converts the received infrared signal into an electrical signal.

[0033] 4. Signal amplification: The electrical signal is amplified by the amplifier circuit for further processing.

[0034] 5. Signal processing: The amplified signal is sent to the counting circuit for digital processing and counting operations.

[0035] 6. Counting display: The counting circuit displays the counting results in digital form on the display screen to show the number of times the object passes through.

[0036] The advantages of infrared counters are that they enable non-contact counting and are characterized by speed, accuracy, and reliability. Furthermore, infrared light is not affected by interference in most environments, ensuring stable operation.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
