Its appearance is in the shape of a cup and can be used for frozen foods and hot drinks. In order to detect the quality of the paper cups manufactured by the paper cup machine, although a detection device is configured on the existing paper cup machine production line, the content of its detection is not comprehensive enough and can only detect a single parameter. Therefore, it is very difficult to find other problems existing in the paper cups, which easily causes the scrapping of paper cups in the same batch and increases the production cost.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention will be further described below in conjunction with the embodiments.

[0029] Example: Refer to the attached Figure 1 -Attached Figure 7 As shown in the figure, a high-speed paper cup machine with random detection includes a paper cup machine body and a discharge pipe 1 arranged at the discharge end of the paper cup machine body. In the paper cup machine, after the paper cups are made, the paper cups are packaged through the discharge pipe 1 arranged at the discharge end. Since the existing paper cup machines can only detect paper cups by manual sampling, the detection efficiency is low.

[0030] A fixed frame 2 is fixedly connected to the lower side of the paper cup machine body. A material receiving pipe 11 is fixedly installed at the lower end of the fixed frame 2. A rotating plate 3 is also rotatably connected to the upper side of the fixed frame 2. A vertical pipe 6 and a bent pipe 7 are fixedly installed on the upper side of the rotating plate 3 respectively. By providing the rotating plate 3 rotatably connected to the fixed frame 2, and the rotating plate 3 is fixed to the output end of the servo motor. By controlling the servo motor, it can rotate at an angle relative to the fixed frame 2, so that the vertical pipe 6 or the bent pipe 7 can correspond to the position of the discharge pipe 1. Specifically, in order to ensure the randomness of sampling in the paper cup machine, the servo motor is controlled to rotate forward and backward by pulse and direction adjustment. If it is a PLC, Y0 sends pulses and Y1 controls the direction, that is, the on-off of Y1 controls the forward and backward rotation of the servo motor. And it is worth noting that in this case, while controlling the forward and backward rotation of the servo motor, it is also necessary to control the angle of each rotation of the rotating plate 3 by means of the control mechanism on the outer wall. Specifically, the included angle between the vertical pipe 6 and the bent pipe 7 is the angle of each forward or backward rotation of the servo motor, so as to ensure that when the paper cup falls from the discharge pipe 1, it can be accurately received by the vertical pipe 6 and the bent pipe 7. And in this case, at the pipe fittings connection for transporting the paper cup, for the pipe fittings located at the lower side, a funnel ring with an open mouth is fixedly connected to the upper end of each of them, increasing the fault tolerance during the transmission of the paper cup.

[0031] It further includes an auxiliary positioning mechanism disposed between the middle of the fixed frame 2 and the rotating plate 3, which is used to fix the relative positions of the fixed frame 2 and the rotating plate 3 after the position adjustment. Specifically, in the actual use process, the servo motor drives the set rotating plate 3 to adjust its position relative to the fixed frame 2. Although the rotation angle of the rotating plate 3 relative to the fixed frame 2 can be limited by means of an external control mechanism each time, during the actual adjustment process, the rotating plate 3 still has a tendency to move along the adjustment direction due to its own inertia. Therefore, in this case, through the set auxiliary positioning mechanism, on the one hand, it can limit the movement trajectory of the rotating plate 3, and at the same time, it can also assist in maintaining the relative position between the rotating plate 3 and the fixed frame 2 after the adjustment is completed. Specifically, the set auxiliary positioning mechanism includes an annular plate 4 fixedly installed on the outer wall of the rotating plate 3. A limiting groove is opened on the bottom surface of the annular plate 4, and a positioning groove is opened on the inner wall of the limiting groove. It also includes a telescopic rod 5 fixedly installed on the fixed frame 2. The set telescopic rod 5 includes a round rod and a sleeve sleeved on its outer wall, and the round rod is elastically connected to the fixed frame 2. The upper end of the telescopic rod 5 is slidably matched with the limiting groove, and the telescopic rod 5 can be inserted and matched with the positioning groove. When the set rotating plate 3 adjusts its position relative to the fixed frame 2, at this time, the telescopic rod 5 installed on the fixed frame 2 will slide along the inner wall of the limiting groove opened on the bottom surface of the annular plate 4. When the servo motor is powered off, the rotating plate 3 still has a tendency to continue rotating due to inertia. At this time, combined with the insertion relationship between the end of the set telescopic rod 5 and the positioning groove, it can ensure the relative position fixation of the rotating plate 3 and the fixed frame 2. When ensuring the relative position fixation of the rotating plate 3 and the fixed frame 2, that is, it can ensure that the upper openings of the vertical pipe 6 or the bent pipe 7 are aligned, ensuring the normal dropping of the paper cup or accurate sampling.

[0032] Specifically, when adjusting the angle between the rotating plate 3 and the fixed frame 2, when the upper end of the vertical pipe 6 is aligned with the position of the discharge pipe 1, since the position of the set receiving pipe 11 is fixed relative to the position of the fixed frame 2, and a through groove 301 is opened at the position on the rotating plate 3 corresponding to the lower end of the vertical pipe 6, combined with the attachment Figure 5 shown in the figure, it is worth noting that in the vertical direction, the positions of the set discharge pipe 1 and the receiving pipe 11 correspond to each other. Therefore, when the set vertical pipe 6 corresponds to the position of the discharge pipe 1, at this time, in the vertical direction, the paper cup can pass through the discharge pipe 1, the vertical pipe 6, the through groove 301 in sequence, and finally fall into the inside of the receiving pipe 11. The counter 8 arranged on one side of the through groove 301 can record the number of paper cups passing through the through groove 301, which is convenient for calculating the proportion of damaged paper cups in the sampled paper cups later, and is used to evaluate the overall quality of the paper cups in the same batch.

[0033] When the upper end of the bent pipe 7 is aligned with the position of the discharge pipe 1, the paper cup can be sampled. Specifically, after the servo motor rotates a certain angle, the upper port position of the bent pipe 7 corresponds to the lower discharge port position of the discharge pipe 1. At this time, the paper cup can move along the trajectory of the set bent pipe 7. The end of the bent pipe 7 is rotatably connected to a first discharge plate 9. A positioning plate 10 is also provided at the end position of the bent pipe 7, which can adjust the position of the paper cup falling from the bent pipe 7. The positioning plate 10 is fixedly connected to the bent pipe 7 through an elastic ring 1001, and the positioning plate 10 corresponds to the position of the first discharge plate 9. A toggle plate 901 is also fixedly connected to the outer wall of the first discharge plate 9. When the paper cup moves downward along the trajectory of the bent pipe 7, due to the action of gravitational potential energy, it will contact the outer wall of the positioning plate 10. Therefore, the significance of setting this positioning plate 10 is to buffer the falling preparation, and combined with the attachment Figure 5 As shown in the figure, when the paper cup is buffered by the positioning plate 10, its position will be at the position of the set first discharge plate 9. Combining the rotational connection relationship between the set first discharge plate 9 and the bent pipe 7, the first discharge plate 9 can be driven to rotate by an external motor, so that the paper cup can roll along the slope 13 of the set inclined plate 12 into the interior of the set connecting pipe 14 for subsequent detection of the paper cup.

[0034] In this paper cup machine, after the paper cup is made, a detection mechanism is also provided at the discharge position, specifically set on the upper side of the fixed frame 2, for detecting the integrity of the bottom of the paper cup and the diameter of the cup body; the detection mechanism includes a connecting pipe 14 fixedly installed on the fixed frame 2. One end of the connecting pipe 14 is rotatably connected to a second discharge plate 15, and a ring-shaped block 16 is fixedly installed at this end of the connecting pipe 14. An ultraviolet analyzer 17 is fixedly installed in the middle of the ring-shaped block 16. The detection mechanism also includes a moving plate 19 movably connected to the connecting pipe 14, and the moving plate 19 is fixedly connected to the output end of an external hydraulic cylinder 20. A measuring column 21 is fixedly installed on the outer wall of the moving plate 19. A laser rangefinder probe is fixedly installed on the outer wall of the measuring column 21, and a lapping plate 22 is elastically connected to the outer wall of the moving plate 19. Specifically, in the actual detection process, when the set paper cup falls into the interior position of the connecting pipe 14 along the inclined plate 12 arranged between the middle of the connecting pipe 14 and the bent pipe 7, the moving plate 19 movably connected inside the connecting pipe 14 can drive the set paper cup to move to the end of the connecting pipe 14, the position of the ring-shaped block 16 under the push of the external hydraulic cylinder 20, for detecting the integrity of the bottom of the paper cup and the diameter of the cup body.

[0035] A fixing plate 18 is fixedly installed on the outer wall of the lower end of the connecting pipe 14 for limiting the movement track of the moving plate 19. The moving plate 19 is connected to the overlapping plate 22 through a spring 2201, and the outer wall of the overlapping plate 22 can overlap with the outer wall of the paper cup. When the moving plate 19 is driven by the external hydraulic cylinder 20 and moves towards the annular block 16, it can drive the paper cup to adjust its position so that it can be accurately located at the detection position. The emitting end of the ultraviolet analyzer 17 is arranged at the axis position of the annular block 16. Along the pushing direction of the hydraulic cylinder 20, the inner diameter of the annular block 16 gradually becomes smaller, and a conical block 1501 is fixedly installed on the outer wall of the second discharge plate 15, which can cooperate with the annular block 16 to adjust the position of the paper cup to be detected. Specifically, the taper of the inner wall of the conical block 1501 is set to be consistent with the inclination of the annular block 16. Then, when the paper cup is moved to this position, its position starts to be adjusted adaptively, and finally, the center position of the bottom of the paper cup can correspond to the position of the ultraviolet analyzer 17 fixedly installed at the axis position of the annular block 16. By setting the ultraviolet analyzer 17, parameters such as the light transmittance of the bottom of the cup (the thickness of the bottom of the paper cup can be detected by observing its light transmittance) and the reflectance (judging whether excessive fluorescent agents are added to the bottom material of the cup by observing its reflectance degree) can be detected.

[0036] And a measuring column 21 fixedly installed on the outer wall of the moving plate 19. A laser rangefinder probe is fixedly installed on the outer wall of the measuring column 21. When the position of the paper cup is fixed inside the annular block 16, the roundness of the cup body and the cup mouth position can be measured through the laser rangefinder probes symmetrically arranged on the outer wall of the measuring column 21. When the values actually measured by the two laser rangefinder probes are within 0 - 0.2 cm, it is in a qualified state. When there is a large gap between the two data, it is an unqualified paper cup, and corresponding rejection is made.

[0037] It also includes a recycling mechanism for collecting the tested paper cups. The recycling mechanism includes a receiving pipe 23 movably arranged relative to the fixed frame 2, and its position is adjusted by an external linear motor. A bent plate 24 is fixedly installed at the upper end of the receiving pipe 23. Specifically, the set recycling mechanism includes two parts. One is the normal recycling of the paper cups that pass the test, and the other is that when the paper cups that fail the test are detected by the set detection mechanism, the paper cups are removed. Specifically, when the paper cups pass the test by the set detection mechanism, first, the set hydraulic cylinder 20 can drive the set moving plate 19 to reset. At this time, the tested paper cups are still between the middle parts of the annular block 16 and the conical block 1501. And it is worth noting that the test result will be transmitted to the controller in the form of an electrical signal, such as inside a PLC. The electrical signal output from its output end can control the external linear motor to adjust the position of the set receiving pipe 23, so that the qualified paper cups can be conveyed along the receiving pipe 23, while the unqualified paper cups will be removed by the bent plate 24 fixedly installed on the receiving pipe 23.

[0038] Particularly, a fixing ring 25 is sleeved on the upper side wall of the receiving pipe 23. An inclined groove 2501 is formed in a ring structure on the inner wall of the fixing ring 25, and the inclined groove 2501 is communicated with the air suction holes 2301 formed on the outer wall of the receiving pipe 23. A ring belt 26 is fixedly installed on the outer wall of the fixing ring 25. An annular groove is formed inside the ring belt 26, and a connection hole is formed on the groove wall of the annular groove and is communicated with the inclined groove 2501. And the annular groove is communicated with the suction end of an external air extraction pump through a connecting pipe 27. Through the communication relationship among the set connecting pipe 27, ring belt 26, inclined groove 2501 and air suction holes 2301, the external air extraction pump can suck the paper cups falling into the receiving pipe 23 through the set air suction holes 2301, so that they have a certain kinetic energy, so as to move better in the receiving pipe 23. It also includes a connecting sleeve 32 sleeved at the end of the receiving pipe 23. The connecting sleeve 32 can ensure that when the linear motor drives the receiving pipe 23 to adjust its position, it can still be communicated with the material receiving pipe 11 to perform the packing operation on the paper cups. A connecting plate 2302 is fixedly installed on the outer wall of the receiving pipe 23 at the position inside the connecting sleeve 32. And combined with the communication relationship between the set receiving pipe 23 and the material receiving pipe 11, the paper cups with a certain kinetic energy can stably fall into the inside of the material receiving pipe 11, which is convenient for the batch packing of the subsequent packing system.

[0039] An auxiliary discharging mechanism is also provided on the connecting sleeve 32, which includes a piston cylinder A 28 and a piston cylinder B 30 that are kept connected through a connecting hose 29. The piston rod movably connected in the piston cylinder A 28 is fixedly connected to the connecting plate 2302, while the piston rod movably connected in the piston cylinder B 30 is hinged to the pushing plate 31 rotatably connected to the horizontal plate 201. And the pushing plate 31 is located on one side of the upper end of the receiving pipe 23. A horizontal plate 201 is also fixedly installed on the outer wall of the fixed frame 2, and the outer wall of the horizontal plate 201 is inserted and matched with the avoidance groove 2401 opened on the bent plate 24. The purpose of setting this auxiliary discharging mechanism is that when the detection mechanism detects that the paper cup is a non-conforming product, the set linear motor will drive the receiving pipe 23 to adjust its position, so that the position of its upper port is not aligned with the set second discharging plate 15. Therefore, the non-conforming paper cup will not fall into the inside of the receiving pipe 23. And when the set linear motor drives the set receiving pipe 23 to shift its position, the bent plate 24 fixedly installed on the receiving pipe 23 will contact the paper cup. And combined with the connection relationship between the piston cylinder A 28 and the piston cylinder B 30, at this time, the piston rod in the piston cylinder B 30 will drive the pushing plate 31 to rotate, and adjust the falling direction of the paper cup, so as to ensure the precise rejection of the non-conforming paper cup.
