Description

Technical Field

[0001] This utility model relates to a paper cup machine. Background Technology

[0002] Paper cup machines are used to produce paper cups (including paper bowl-type paper cups). The cup bottom needs to be formed, which relies on a forming turntable. Cup mold devices (including vertical cup molds) are evenly distributed around the turntable's circumference. The turntable rotates intermittently around a vertical axis to allow the cup mold devices to cooperate in forming operations at various stations. The cup bottom requires multiple processes such as heating, rolling, and pressing. In high-speed paper cup machines (typically producing 110 or more paper cups per minute), the turntable is prone to vibration during rapid operation, affecting stability and even hindering further speed increases. Furthermore, it has been found that the formed cup bottoms are inconsistent after production, affecting product quality. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a high-speed paper cup machine automatic height setting device that is stable in operation and can improve the quality of finished products.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic height-fixing device for a high-speed paper cup machine, comprising a support frame, a cup height-fixing pusher, and a linkage transmission mechanism, characterized in that: the cup height-fixing pusher is installed on a lifting movable frame, the cup height-fixing pusher is positioned above the forming turntable of the paper cup machine, the cup height-fixing pusher is set downwards, the lifting movable frame is set on the support frame, the linkage transmission mechanism includes a swing arm, a first connecting rod, and a second connecting rod, the swing arm is hinged to the support frame, and a rolling lifting assembly plate of the paper cup machine is also provided below the forming turntable, the swing arm is connected to the rolling lifting assembly plate through the first connecting rod, and the swing arm is connected to the lifting movable frame through the second connecting rod.

[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0006] For example, the support frame includes a support plate located above the forming turntable. The support plate is equipped with a support shaft located next to the forming turntable. The support plate is also connected to the vertical rotating shaft of the forming turntable. The support shaft is installed on the machine frame table. The lifting frame includes an upper pull plate, a vertical guide rod, and a lower pull plate. The vertical guide rod is connected between the upper pull plate and the lower pull plate. The support frame is equipped with a guide sleeve installed on the support plate. The vertical guide rod is configured on the guide sleeve. The upper pull plate is located on the upper side of the support plate, and the lower pull plate is located on the lower side of the support plate. One end of the second connecting rod is hinged to the upper pull plate, and the other end of the second connecting rod is hinged to the swing rod. The cup body height-fixing push head is installed on the lower pull plate. A hinge seat is provided on the support plate for the swing rod to connect. The hinge seat is located on the upper side of the support plate. For example, two support shafts are provided, and the support shafts and the rotating shaft form a triangular support structure; at least three guide sleeves are provided on the support plate, and each guide sleeve is equipped with a vertical guide rod, and three guide rods are provided to form a triangular support structure.

[0007] The cup-body height-fixing pusher descends to cooperate with the vertical cup mold on the forming turntable to determine the height position of the cup body.

[0008] For example, the roller pressing and lifting assembly plate is equipped with the cup bottom heating mechanism, the bottom rolling mechanism and the rolling mechanism of the paper cup machine.

[0009] For example, the cup bottom heating mechanism is divided into a first heating mechanism and a second heating mechanism. The first heating mechanism, the second heating mechanism, the bottom rolling mechanism, and the rolling mechanism are respectively configured at the four cup mold stopping positions of the forming turntable.

[0010] The lifting frame is equipped with corresponding cup-body height-fixing push heads, which are paired with various mechanisms on the rolling lifting assembly plate.

[0011] Each mechanism on the roller pressing and lifting assembly plate corresponds to a specific work station, which are arranged along the rotation direction of the paper cup forming turntable.

[0012] For example, four sets of cup height-fixing push heads are set on the rolling lifting assembly plate, and the four sets of cup height-fixing push heads are paired with the four mechanisms on the rolling lifting assembly plate one by one.

[0013] For example, the cup body height-fixing push head includes a height-fixing screw, and the lifting frame is provided with a threaded hole, which is connected to the height-fixing screw; the height-fixing screw is also equipped with a locking nut; the first connecting rod is a long connecting rod, and the second connecting rod is a short connecting rod.

[0014] The beneficial effects of this utility model are as follows: the automatic height setting device of the high-speed paper cup machine detects that the deviation of the product is caused by the slight movement of the cup body (such as the cylinder) during the cup bottom forming process due to being pushed upwards. Through the linkage transmission mechanism, the cup body height setting push head is driven in a timely and efficient manner to automatically limit the height of the cup body, ensuring that the cup body is in a uniform limited height position and guaranteeing the quality of the product after forming. The mechanical linkage transmission has a high degree of coordination, timely response, stable operation, and more accurate height setting (limiting height) position. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Referring to the accompanying drawings, in this embodiment, the high-speed paper cup machine automatic height-fixing device includes a support frame 1, a cup body height-fixing push head 2, and a linkage transmission mechanism 3. The cup height-fixing pusher 2 is installed on the lifting frame 4 so that the cup height-fixing pusher 2 moves up and down together with the lifting frame 4. The cup height-fixing pusher 2 is positioned above the forming turntable 5 (of the paper cup machine) with the cup height-fixing pusher 2 facing downwards. The lifting frame 4 is mounted on the support frame 1, and the support frame 1 supports the lifting frame 4 for lifting and lowering. The linkage transmission mechanism 3 includes a swing rod 30, a first connecting rod 31, and a second connecting rod 32. The swing rod 30 is hinged to the support frame 1. Below the forming turntable 5, there is also a rolling lifting assembly plate 6 (of the paper cup machine). The paper cup machine has a rolling lifting assembly plate 6 for installing rolling devices, etc., so that when rising, it can cooperate to roll the bottom of the cylinder (on the vertical cup mold of the forming turntable 5) (a mature technology). In this invention, the rolling lifting assembly plate 6 is used as the power unit to drive the cup height-fixing pusher 2 to move up and down, achieving mechanical linkage and transmission. The linkage is high, the response is timely, the operation is stable, and the height (limit) position is more accurate. Specifically, the swing rod 30 is connected to the rolling lifting assembly plate 6 through the first connecting rod 31, and the swing rod 30 is connected to the lifting movable frame 4 through the second connecting rod 32. The lifting action of the rolling lifting assembly plate 6 drives the swing rod 30 to swing back and forth through the first connecting rod 31. The swing rod 30 swings back and forth through the second connecting rod 32 to drive the lifting movable frame 4 to descend and rise. The lifting movable frame 4 (and the cup height-fixing pusher 2 on it) and the rolling lifting assembly plate 6 operate in mechanical linkage, so as to realize the automatic height-fixing of the cup height-fixing pusher 2.

[0020] During operation, when the rolling lifting assembly plate 6 rises to cooperate with the rolling of the cup body (such as the cylinder body), there is a risk of pushing the cup body upward and causing it to move. At this time, the rising of the rolling lifting assembly plate 6 can be timely driven by the linkage transmission mechanism 3 to lower the lifting movable frame 4. The cup body height-fixing push head 2 and the lifting movable frame 4 will descend together. The cup body height-fixing push head 2 will limit the height position of the cup body, preventing the cup body from being pushed upward and causing it to move, thus ensuring product quality and avoiding the uncertainty of such slight movement (hidden defects are not easy to detect) which may lead to inconsistent product forming and deviations. When the rolling lifting assembly plate 6 is lowered, the linkage transmission mechanism 3 will timely drive the lifting movable frame 4 and the cup body height-fixing push head 2 to rise and reset, waiting for the next operation.

[0021] The automatic height setting device of this high-speed paper cup machine found that the deviation in the product was caused by the slight movement of the cup body (such as the cylinder) during the forming process due to being pushed upwards. Through the linkage transmission mechanism 3, the cup body height setting push head 2 is driven in a timely and efficient manner to automatically limit the height of the cup body, ensuring that the cup body is in a uniform limited height position and guaranteeing the quality of the product after forming. The mechanical linkage transmission has a high degree of coordination, timely response, stable operation, and more accurate height setting (limiting height) position.

[0022] Based on the above embodiments, the following optimizations or further explanations can be made.

[0023] For example, the support frame 1 includes a support plate 10, which is located on the upper side of the forming turntable 5. The support plate 10 is equipped with a support shaft 11, which is located next to the forming turntable 5. The support plate 10 is also connected to the vertical rotating shaft 50 of the forming turntable 5. The support shaft 11, the vertical rotating shaft 50, and the support plate 10 of the support frame 1 support each other to form a stable structure, so that the forming turntable 5 can rotate stably around the vertical rotating shaft 50. During the high-speed forming process, this helps to improve the quality of the finished product. Moreover, the support plate 10 can straddle the forming turntable 5 to form support so that the cup body height-fixed push head 2 can operate stably. The support shaft 11 is installed on the machine frame table 7 (such as a table plate).

[0024] For example, the lifting frame 4 includes an upper pull plate 41, a vertical guide rod 42, and a lower pull plate 43. The vertical guide rod 42 connects the upper pull plate 41 and the lower pull plate 43. A guide sleeve 12 is provided on the support frame 1 and is installed on the support plate 10. The vertical guide rod 42 is disposed on the guide sleeve 12. The upper pull plate 41 is located on the upper side of the support plate 10, and the lower pull plate 43 is located on the lower side of the support plate 10. One end of the second connecting rod 32 is hinged to the upper pull plate 41, and the other end of the second connecting rod 32 is hinged to the swing rod 30. The cup-body height-fixing push head 2 is installed on the lower pull plate 43. A hinge seat 13 is provided on the support plate 10 for the swing rod 30 to connect. The hinge seat 13 can be located on the upper side of the support plate 10. The swing rod 30 swings on the support and drives the upper pull plate 41 to rise and fall through the second connecting rod 32, so that the entire lifting frame 4 rises and falls together. For example, the first link 31 is a long link, the second link 32 is a short link, and the two ends of the swing arm 30 are respectively hinged to the first link and the second link.

[0025] In addition, two supporting shafts 11 are provided, forming a triangular support structure with the rotating shaft; three guide sleeves 12 are provided on the support plate 10, and each guide sleeve 12 is equipped with a vertical guide rod 42, forming a triangular support structure. This design is not only compact but also provides stable support.

[0026] The cup height fixing push head 2 descends to cooperate with the vertical cup mold on the forming turntable 5 to limit the height position of the cup body; the cup height fixing push head 2 and the lifting movable frame 4 descend to the position together, and the cup height fixing push head 2 will limit the height position of the cup body.

[0027] In addition, the roller lifting assembly plate 6 is equipped with the cup bottom heating mechanism, the bottom rolling mechanism and the rolling mechanism of the paper cup machine (not shown in the figure). The roller lifting assembly can drive them to rise and fall in a unified manner, and perform cup bottom heating, bottom rolling and rolling operations at the same time. For example, the cup bottom heating mechanism is divided into a first heating mechanism and a second heating mechanism. The first heating mechanism, the second heating mechanism, the bottom rolling mechanism and the rolling mechanism are respectively arranged at the four cup mold stopping positions of the forming turntable 5.

[0028] For example, the lifting frame 4 is equipped with corresponding cup height-fixing pushers 2, which are paired with each mechanism on the rolling lifting assembly plate 6. This results in a higher degree of coordination and uniformity, avoiding height deviations caused by inconsistent lifting. Each mechanism on the rolling lifting assembly plate 6 corresponds to a specific work station, such as a cup bottom heating station (e.g., the first heating station, the second heating station), a bottom rolling station, and a rolling station. These work stations are arranged along the rotation direction of the paper cup machine forming turntable 5, so that the vertical cup mold on the forming turntable 5 can stop at the corresponding work station for operation.

[0029] For example, four sets of cup height-fixing push heads 2 are set on the pull-down plate 43. The four sets of cup height-fixing push heads 2 are paired with the four mechanisms on the rolling lifting assembly plate 6. That is, when the corresponding mechanism at each work station rises, the corresponding cup height-fixing push head 2 will descend to limit the height position of the cup on the corresponding vertical cup mold, so as to prevent the cup from moving upward.

[0030] The cup body height-fixing pusher 2 can be a common limiting pusher; or, more preferably, the cup body height-fixing pusher 2 includes a height-fixing screw 21, and the lifting movable frame 4 (such as the pull-down plate 43) is provided with a threaded hole. The height-fixing screw 21 is connected to the threaded hole so as to adjust the relative height position of the height-fixing screw 21. It can be used to fine-tune the height position, which is more practical and ensures that the height-fixing effect and the height-fixing at different work positions can be adjusted independently without being affected by uniform lifting. The height-fixing screw 21 is also equipped with a locking nut 22. After adjustment, the locking nut 22 locks the height-fixing screw 21 onto the lifting movable frame 4 (such as the pull-down plate 43) to prevent loosening.
