Description

Technical Field

[0001] The utility model relates to the technical field of cardboard production, in particular to a counting device for a paper pasting machine. Background Art

[0002] As one of the key devices in the packaging industry, the paper pasting machine is mainly used to bond pre-printed paper with corrugated cardboard or other substrates to form a composite material with high strength and aesthetics. With the development of technology, modern paper pasting machines have achieved a high degree of automation. They can not only quickly and efficiently complete the lamination of paper and substrates, but also realize a series of complex operations such as automatic feeding, positioning correction, temperature control, and pressure adjustment during the production process. The application of these technologies has greatly improved production efficiency, reduced labor costs, and ensured the stability and consistency of product quality.

[0003] In the design of the paper pasting machine, for the convenience of production and management, a weighing device is usually set at the finished product position to calculate the number of cardboard sheets processed by the paper pasting machine. At the same time, a feeding counting device is also set at the feeding mechanism to count the raw materials entering the machine. These two devices work together, and theoretically, they can achieve precise monitoring of the entire production process. However, in practical applications, due to the influence of various factors, such as the wear of mechanical equipment, the change of sensor sensitivity, or the change of environmental conditions, the counting results of these two devices sometimes show differences. When the counting is inconsistent, manual intervention is required for rechecking. On the one hand, it is to determine which device has an abnormality and promptly carry out maintenance or adjustment; on the other hand, it is also to ensure the accuracy of the final product quantity and avoid economic losses or customer complaints caused by counting errors. The manual intervention in this case not only increases the workload but also may affect production efficiency, bringing an additional cost burden to the enterprise. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a counting device for a paper pasting machine, which solves the technical problem that when the technical device of the existing paper pasting machine has an abnormality, manual rechecking is required.

[0005] According to a counting device for a paper pasting machine recorded in the embodiments of the utility model, the paper pasting machine includes a paper pasting device and a conveying and compressing device arranged in sequence, and the connection part between the paper pasting device and the conveying and compressing device is an inclined structure;

[0006] The counting device includes a support rod arranged at the inclined structure and an elastic guide plate fixed on the support rod. A counter is also arranged on the support rod, and a triggering mechanism is arranged between the counter and the elastic guide plate, and the triggering mechanism is electrically connected to the counter.

[0007] The technical principle of the present utility model is as follows: After the paper mounting device finishes paper mounting, through the inclined structure, when entering the conveying and compressing device, it passes through the lower side of the elastic guide plate, enabling the elastic guide plate to perform a preliminary compaction, and then it is handed over to the conveying and compressing mechanism for compaction.

[0008] When the cardboard passes through the elastic guide plate, the elastic guide plate moves upward, causing the triggering mechanism to be triggered, and then the counter performs a count.

[0009] Compared with the prior art, the present utility model has the following beneficial effects: By adding a counting device between the paper mounting device and the conveying and compressing device, cooperating with the weighing device and the feeding counting device mentioned in the background technology, there will be three counting results. If two of the counting results are the same, then these two are the correct results, and at the same time, it can be determined that the other device is damaged. Therefore, it solves the technical problem that when the technical devices of the existing paper mounting machine are abnormal, manual review is required.

[0010] Further, the triggering mechanism includes a protruding rod fixed on the support rod and a triggering strip fixed on the elastic guide plate. A contact port is provided at the top of the protruding rod, the contact port is aligned with one end of the triggering strip, the contact port is electrically connected to the positive pole of the power supply, the other end of the triggering strip is electrically connected to the counter, and the counter is electrically connected to the negative pole of the power supply.

[0011] Adopting a pure circuit triggering method, compared with other triggering methods, its abnormal probability is low.

[0012] Further, the triggering strip is arranged along the conveying direction of the conveying and compressing device, and the end of the triggering strip close to the paper mounting device is electrically connected to the counter.

[0013] Further, two counters are provided, and each counter is electrically connected to a triggering mechanism.

[0014] Further, one counter is provided, two triggering mechanisms are provided, and the two triggering mechanisms are connected in series with the counter in sequence.

[0015] Further, the triggering mechanism is an infrared sensor or a pressure sensor.

[0016] Further, a cardboard collection box is also provided on the side of the conveying and compressing device away from the paper mounting device, and a weighing device is provided inside the cardboard collection box.

[0017] Further, the side of the paper mounting device away from the conveying and compressing device is a feeding mechanism, and a feeding counting device is provided on the feeding mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0026] Embodiment 1

[0027] As Figure 1 shown in the pasting machine counting device, the pasting machine includes a pasting device 100 and a conveying and compressing device 200 arranged in sequence. The connection between the pasting device 100 and the conveying and compressing device 200 is an inclined structure 110. Specifically, a cardboard collection box 210 is further provided on the side of the conveying and compressing device 200 away from the pasting device 100, and the side of the pasting device 100 away from the conveying and compressing device 200 is a feeding mechanism 120. Among them, the pasting device 100 is used to paste other substrates onto the cardboard; the conveying and compressing device 200 is used to compress the substrate and the cardboard to prevent the two from separating or shifting when the glue is not dry; the cardboard collection box 210 is used to store the finished cardboard.

[0028] Specifically, a feeding counting device is provided on the feeding mechanism 120, and a weighing device is provided in the cardboard collection box 210, which is not shown in the drawings of this application.

[0029] As Figures 2-3 shown, the counting device includes a support rod 300 arranged at the inclined structure 110 and an elastic guide plate 310 fixed on the support rod 300, which preliminarily compresses the cardboard to prevent the substrate from separating from the cardboard, and at the same time ensures that the cardboard smoothly enters the conveying and compressing device 200 to avoid situations such as the cardboard flying up.

[0030] As shown Figures 2-4 in the figure, a counter 320 is further provided on the support rod 300. A triggering mechanism 400 is provided between the counter 320 and the elastic guide plate 310. The triggering mechanism 400 is electrically connected to the counter 320. Specifically, the triggering mechanism 400 includes a protruding rod 410 fixed on the support rod 300 and a triggering strip 420 fixed on the elastic guide plate 310. A contact port 411 is fixed at the top of the protruding rod 410. The contact port 411 is aligned with one end of the triggering strip 420. When the cardboard passes by, the elastic guide plate 310 is lifted to connect the triggering strip 420 with the contact port 411. The contact port 411 is wire-connected to the positive pole of the power supply, the other end of the triggering strip 420 is wire-connected to the counter 320, and the counter 320 is wire-connected to the negative pole of the power supply. The above structure forms a complete circuit, and the counter 320 realizes counting.

[0031] As shown Figure 3 in the figure, the triggering strip 420 is arranged along the conveying direction of the conveying and pressing device 200. One end of the triggering strip 420 close to the pasting device 100 is wire-connected to the counter 320.

[0032] As shown Figures 2-3 in the figure, there are two counters 320, and each counter 320 is electrically connected to a triggering mechanism 400, that is, two count values can be formed. If the two count values are different, the count values of the proportional feeding counting device and the weighing device can be compared to judge whether the counting device is abnormal.

[0033] Embodiment 2

[0034] As shown Figures 5-6 in the figure, the difference between this embodiment and Embodiment 1 is that: there is one counter 320 and two triggering mechanisms 400. The two triggering mechanisms 400 are connected in series with the counter 320 in sequence, that is, counting will only occur when the two triggering mechanisms 400 are triggered simultaneously, which can effectively avoid the upward movement of the elastic guide plate 310 caused by other accidental situations, because this kind of movement is usually on one side and will not trigger the two triggering mechanisms 400 simultaneously.

[0035] Embodiment 3

[0036] The difference between this embodiment and Embodiments 1-2 is that: the triggering mechanism 400 is an infrared sensor or a pressure sensor. For infrared sensing or pressure sensing, it is prone to misjudgment, while the triggering mechanisms 400 in Embodiments 1-2 are not prone to misjudgment.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
