When the packaging bag feeding roller stops conveying, the transmission component stops pushing the material blocking mechanism in opposite directions, so that the two ends of the material blocking mechanism are released and face each other, and the bottom end of the packaging bag can be automatically clamped. Then, the bottom of the packaging bag can be tightened by the downward movement of the material blocking mechanism, so as to avoid wrinkles and ruptures in the seal when the bottom of the packaging bag is loose.

Description

Technical Field

[0001] The invention belongs to the technical field of paper cup packaging machines, in particular to a paper cup packaging machine with an automatic labeling function. Background Art

[0002] Paper cup packaging machine is a kind of mechanical equipment specially used for paper cup packaging. It can improve packaging efficiency and ensure packaging quality. It is widely used in food, beverage, medicine, daily chemical and other industries. Common types include fully automatic paper cup packaging machine, heat shrink packaging machine and vacuum packaging machine. Before paper cup packaging, it is necessary to label the paper cups.

[0015] The limiting rod is movably installed inside the fixing plate, the pressing plate is arranged at the bottom of the limiting rod, and the top of the limiting rod is elastically connected to the top surface of the fixing plate through a connecting spring.

[0016] Preferably, a power assembly is arranged between the fixing plate and the top of the fixing frame, and the power assembly includes a first hydraulic cylinder, a connecting rod, a second hydraulic cylinder, a hydraulic piston rod and an oil hose;

[0017] The first hydraulic cylinder is fixedly installed in the middle of the top of the fixed plate, the connecting rod is movably installed in the inner cavity of the first hydraulic cylinder, and the bottom end is fixedly connected to the top of the pressing plate, the second hydraulic cylinder is arranged in the middle of the top of the fixed frame, the hydraulic piston rod is movably installed in the inner cavity of the second hydraulic cylinder, and the bottom end is fixedly connected to the top of the sliding block, and the top of the first hydraulic cylinder is fixedly connected to the top of the second hydraulic cylinder through an oil hose.

[0018] Preferably, a fixing mechanism is provided in the middle of the transmission plate, and the fixing mechanism includes a toothed rack, a toothed block, and a pneumatic component;

[0020] Preferably, the pneumatic assembly includes a pneumatic cylinder, a pneumatic piston rod, a connecting pipe and a pipeline connecting box;

[0021] The pneumatic cylinder is fixedly installed on the surface of the transmission plate and is located in the middle of the outer side of the rack. The pneumatic piston rod is movably installed in the inner cavity of the pneumatic cylinder, and the inner end of the pneumatic piston rod is fixedly connected to the outer side of the rack.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The above technical solution is implemented by setting up a material blocking mechanism and a transmission assembly. When the packaging bag feeding roller is running to transport the packaging bag, the transmission assembly will drive the two ends of the material blocking mechanism to move in opposite directions, so that the packaging bag can smoothly pass through the packaging tube and pass between the material blocking mechanisms. When the packaging bag feeding roller stops transporting, the transmission assembly will stop pushing the material blocking mechanism in opposite directions, so that the two ends of the material blocking mechanism are released and face each other, which can automatically clamp the bottom end of the packaging bag, and then the bottom of the packaging bag can be tightened by the downward movement of the material blocking mechanism to avoid wrinkles and ruptures in the seal when the bottom of the packaging bag is loose.

[0024] The present invention provides a pressing mechanism and a power component. When the packaging bag in the packaging tube is filled with a suitable number of paper cups, the pressing mechanism will operate to press the top of the paper cup, so that the bottom of the paper cup can be blocked by the blocking mechanism, and the top of one side of the pressing mechanism is compressed. At this time, it can be said that the packaging tube is filled with a certain amount of paper cups, and the top of the pressing mechanism is compressed, so that the power component can drive the blocking mechanism to move downward as a whole, so that the bottom of the packaging bag can be pulled downward.

[0025] The present invention provides a fixing mechanism and a vent pipe. When the power component drives the entire material-blocking mechanism downward, the middle part of the transmission component will also stretch, so that the packaging bag feeding roller can subsequently smoothly drive the transmission component to drive the material-blocking mechanism to release the clamping of the packaging bag in reverse, and then the bottom of the packaging bag is sealed by the sealing mechanism. While the power component is running, pneumatic pressure can enter the fixing mechanism through the vent pipe, and the transmission component can be stretched and clamped to prevent accidental stretching of the transmission component from affecting the subsequent drive of the material-blocking mechanism to move in reverse.

The movable frame 7042 is movably installed on one side of the fixed frame 701 . The movable frame 7042 is elastically connected to one side of the fixed frame 701 through a power spring 7043 .

[0043] The above solution is adopted: by providing a power spring 7043, the elastic force of the power spring 7043 can push the two movable frames 7042 and the driven gear block 7041 to drive the two material blocking rollers 703 to move towards each other.

[0048] The above scheme is adopted: by providing a gear rod 801, when the gear rod 801 is driven to rotate, the teeth on the surface of the gear rod 801 will squeeze the teeth on the inner side of the driven gear block 7041, thereby pushing the two driven gear blocks 7041 and the material blocking roller 703 to move towards each other as a whole, so as to release the clamping effect on the bottom of the packaging bag.

[0051] The above solution is adopted: by providing a pneumatic cylinder 901, when the pneumatic cylinder 901 is in operation, it can drive the fixing plate 902 and the pressing assembly 903 as a whole downward, so as to assist in pressing and stacking the paper cups inside the packaging tube 4.

[0052] like Figure 5 As shown, the pressing assembly 903 includes a pressing plate 9031, a limiting rod 9032 and a connecting spring 9033;

[0053] The limiting rod 9032 is movably installed inside the fixing plate 902 , the pressing plate 9031 is arranged at the bottom of the limiting rod 9032 , and the top of the limiting rod 9032 is elastically connected to the top surface of the fixing plate 902 via a connecting spring 9033 .

[0054] The above scheme is adopted: by providing a connecting spring 9033, when the pressing plate 9031 is squeezed and pushed upward, the connecting spring 9033 will be stretched at the same time, and when the squeezing force at the bottom of the pressing plate 9031 is released, the tension of the connecting spring 9033 will be released, thereby pulling the limit rod 9032 and the pressing plate 9031 to reset downward as a whole.

[0057] The above scheme is adopted: by providing a connecting rod 102, when the pressing plate 9031 is squeezed and pushed upward as a whole, the connecting rod 102 will push the hydraulic oil at the top of the inner cavity of the first hydraulic cylinder 101 into the second hydraulic cylinder 103 through the oil hose 105, thereby pushing the hydraulic piston rod 104 to drive the sliding block 702 and the material blocking roller 703 to move downward as a whole.

[0058] like Figure 8 and Fig. 9 As shown, a fixing mechanism 11 is disposed in the middle of the transmission plate 803, and the fixing mechanism 11 includes a latching rack 1101, a latching rack block 1102, and a pneumatic component 1103;

[0059] The rack 1101 is movably mounted on the inner wall of the middle part of the transmission plate 803 , the rack block 1102 is arranged on the middle surface of the transmission plate 803 and is located above the rack 1101 , and the pneumatic component 1103 is arranged on the surface of the transmission plate 803 and is located outside the rack 1101 .

[0060] By adopting the above solution, the latching tooth block 1102 is provided. When the latching tooth block 1102 moves toward each other, the latching teeth on the inner side of the latching tooth block 1102 and the latching rack 1101 will be engaged with each other, so that the middle part of the transmission plate 803 can be fixed.

[0061] like Figure 8 and Fig. 9As shown, the pneumatic assembly 1103 includes a pneumatic cylinder 11031, a pneumatic piston rod 11032, a connecting pipe 11033 and a pipeline connecting box 11034;

[0062] The pneumatic cylinder 11031 is fixedly installed on the surface of the transmission plate 803 and is located in the middle of the outer side of the rack 1101.

[0063] The above scheme is adopted: by providing a ventilation pipe 12, when the gas in the inner cavity at the bottom of the second hydraulic cylinder 103 is pushed through the ventilation pipe 12 to enter the interior of the pipeline connection box 11034, the air pressure inside the pipeline connection box 11034 will increase, and the internal gas of the pipeline connection box 11034 can be pushed to enter the interior of the pneumatic cylinder 11031 through the connecting pipe 11033, thereby pushing the pneumatic piston rod 11032 and the rack 1101 to move towards each other smoothly.

[0064] The working principle and use process of the present invention:

[0065] First, the paper cups can be transported to the position of the automatic labeling mechanism 2 for automatic labeling. At this time, the packaging bag feeding roller 3 can be driven simultaneously to transport the packaging bag into the packaging tube 4, and the bottom end is located below the blocking mechanism 7. Then the packaging bag feeding roller 3 is stopped, and then the gear rod 801 stops rotating, so that the elastic force of the power spring 7043 is released and the two movable frames 7042 are smoothly pushed to drive the two driven gear blocks 7041 and the blocking roller 703 to move towards each other as a whole, so that the bottom of the packaging bag can be clamped by the blocking roller 703.

[0066] Then, the labeled paper cups can be transported to the inside of the packaging tube 4 for stacking. At this time, the pneumatic cylinder 901 can be started to drive the fixed plate 902 and the pressing assembly 903 to press the paper cups downward to assist in stacking. When the packaging tube 4 is filled with a certain amount of paper cups, the pressing plate 9031 and the limit rod 9032 will be squeezed upward, and at the same time, the connecting rod 102 will be pushed upward, so that the hydraulic oil at the top of the inner cavity of the first hydraulic cylinder 101 is pushed through the oil hose 105 into the second hydraulic cylinder 103, so that the hydraulic pressure in the inner cavity of the second hydraulic cylinder 103 becomes larger, and the hydraulic piston rod 104 is pushed to drive the sliding block 702 and the material blocking roller 703 downward as a whole, so that the bottom of the packaging bag is stretched to the top of the sealing mechanism 5, and then it can be sealed. The sealed bag can slide down and be discharged through the unloading slide 6.

[0067] When the hydraulic piston rod 104 moves downward, it will push the gas at the bottom of the inner cavity of the second hydraulic cylinder 103 through the ventilation pipe 12 to enter the pipeline connection box 11034, and then enter the pneumatic cylinder 11031 through the connecting pipe 11033, so as to push the two pneumatic piston rods 11032 and the card rack 1101 towards each other, so that after the middle part of the transmission plate 803 is stretched, the card rack block 1102 is engaged with the card rack 1101, so that the middle part of the transmission plate 803 can be stretched and fixed, so that the subsequent packaging bag feeding roller 3 can run, and the gear rod 801 can be driven to rotate smoothly through the connecting block 802 and the transmission plate 803, and the two driven gear blocks 7041 and the material blocking roller 703 are pushed to move in opposite directions, thereby releasing the clamping of the packaging bag and facilitating the subsequent overall upward reset of the material blocking mechanism 7.
