Description

Technical Field

[0001] The invention belongs to the technical field of cigarette packaging machines, and in particular relates to a pressure plate detection device for a packaging machine. Background Art

[0002] The channel pressure plate's primary function is to locate cigarette packs within the channel and detect deformed packs. The channel pressure plate is hinged. When too many cigarette packs are stacked at the stacking station or deformed packs appear in the output channel, the channel pressure plate is lifted, causing the equipment to shut down. The detector is located above the center of the channel pressure plate, 6mm from the pressure plate, and has an effective detection range of 0-4mm. Because the stacking station is relatively close to the pressure plate hinge, the principle of lever force can cause the pressure plate to be insufficiently lifted when stacking three packs at the stacking station, leading to no signal detection. This can cause excessive cigarette packs to accumulate at the stacking lift, causing the equipment to become stuck and shut down. Summary of the Invention

[0003] The purpose of the present invention is to provide a packaging machine pressure plate detection device to solve the problem that the detector in the existing technology has insufficient pressure plate lifting height and no signal is detected when 3 packs of cigarettes are stacked at the stacking station, resulting in excessive stacking of cigarette packs at the stacking lifting point and the equipment being stuck and shut down.

DETAILED DESCRIPTION

[0022] The technical solutions of the present invention are described in detail below through examples. The following examples are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and cannot be interpreted as limiting the technical solutions of the present invention.

[0023] In the technical solution of the present application, "front", "back", "right", "up" and "down" do not necessarily refer to specific directions. They are necessary positioning for the purpose of illustrating the needs of the technical solution. When the position is changed, it does not affect the implementation of the technical solution of the present application.

[0024] like Figure 1 As shown, the present application provides a packaging machine pressure plate detection device, including a stacking station cigarette pack pressure plate assembly, a fixed bracket 1 and a channel cigarette pack pressure plate assembly; the stacking station cigarette pack pressure plate assembly and the channel cigarette pack pressure plate assembly are both installed on the fixed bracket 1, Figure 1 The left side in the middle is the stacking station cigarette pack pressing plate assembly, and the right side is the channel cigarette pack pressing plate assembly.

[0025] The stacking station cigarette pack pressing plate assembly includes a front movable pressing plate 3, a rear movable pressing plate 2, a first detector 4, and a connecting base 8. The first detector 4 is mounted on the fixed bracket 1 via a first bracket 5. The front movable pressing plate 3 and the rear movable pressing plate 2 are mounted on the connecting base 8 via a first screw shaft 15. When in use, the front movable pressing plate and the rear movable pressing plate remain substantially parallel. The structures of the front movable pressing plate and the rear movable pressing plate are different. Specifically, the rear movable pressing plate 2 is provided with an upward protrusion within the range of the first detector 4 to improve the detection sensitivity of the first detector.

[0026] In the technical solution of the present application, the connecting seat 8 includes a connecting seat body, two opposite upwardly extending mounting parts are arranged on the right upper surface of the connecting seat body, and relative mounting holes are arranged on the mounting parts. The lower end of the fixed bracket is located between the two mounting parts and is connected using a connecting shaft. After installation, the connecting seat and the lower end of the fixed bracket can rotate relative to each other, so that the connecting seat can drive the front movable pressure plate and the rear movable pressure plate to be lifted.

[0027] A first compression spring 7 is arranged between the connecting seat and the lower end surface of the fixed bracket. In the technical solution of the present application, a third screw shaft 6 is also arranged on the connecting seat 8. The first compression spring 7 is sleeved on the third screw shaft 6. The upper end of the third screw shaft penetrates into the lower end of the fixed bracket, which is used to apply a certain pressure to the front movable pressure plate and the rear movable pressure plate to prevent them from being lifted up easily, causing the first detector to detect that the rear movable pressure plate is lifted up, causing the packaging machine to stop.

[0028] The channel pressure plate assembly includes a channel pressure plate 9, a second bracket 12, two second screw shafts 10, two second compression springs 11 and a second detector 14; the second bracket 12 is installed on the fixed bracket 1, and two mounting holes are provided on the second bracket. The lower ends of the two second screw shafts are vertically fixed to the upper surface of the channel pressure plate, and the two second compression springs are correspondingly sleeved on the two second screw shafts. The two second screw shafts pass through the two mounting holes and are threadedly connected with nuts. The parallelism between the channel pressure plate and the cigarette pack is adjusted by adjusting the nut to ensure smooth operation of the cigarette pack in the channel.

[0029] The second detector 14 is installed on the second bracket 12 through the third bracket 13. The second detector corresponds to the upper surface of the channel pressure plate and is used to detect the lifting action of the channel pressure plate and transmit the detection signal to the controller, which controls the packaging machine to stop.

[0030] In the technical solution of the present application, the lower end surface of the fixed bracket includes a flat portion and an inclined portion. The flat portion is rotatably connected to the connecting seat, and the inclined portion is used to prevent the front movable pressure plate and the rear movable pressure plate from being interfered with by the lower end of the fixed bracket after the connecting seat is lifted up when the front movable pressure plate and the rear movable pressure plate are squeezed by the cigarette pack.

[0031] The left end of the channel pressure plate is located below the connecting seat. The channel pressure plate is an integrated structure consisting of a first pressure plate portion and a second pressure plate portion, wherein the thickness of the first pressure plate portion is greater than that of the second pressure plate portion, and the two second screw shafts are both provided on the upper surface of the first pressure plate portion;

[0032] The upper surface of the first pressing plate portion and the upper surface of the second pressing plate portion are both in the same plane.

[0033] The second bracket includes a vertical portion and a horizontal portion, the vertical portion is fixedly connected to the fixing bracket; the mounting hole is provided on the horizontal portion.

[0034] When a deformed cigarette pack appears at the stacking station or three packs of cigarettes are stacked, the front and rear movable pressure plates are lifted up by the cigarette packs, the first detector detects a signal and provides the detected signal to the controller, which controls the packaging machine to stop for maintenance.

[0035] When a deformed cigarette pack passes through the stacking station without being detected, when it enters the channel pressure plate assembly, its deformed part will push the channel pressure plate upward. The corresponding signal is detected by the second detector and transmitted to the controller, which controls the packaging machine to stop for maintenance.

[0036] Deformed cigarette packs can be detected in a timely manner at the stacking station and cigarette pack channel, avoiding damage to parts caused by detection delays, and transporting cigarette packs smoothly, reducing the number of maintenance times, lowering maintenance costs, and eliminating quality risks.

[0037] The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
