The cup mouth and the curling edge mechanism have a good fit. The preheating by the independently set heating mechanism ensures effective softening and subsequent curling effect. It solves the technical problems in the prior art such as poor fit between the cup mouth and the curling edge mold, lack of preheating or poor heating effect, and unsatisfactory curling effect.

Description

Technical Field

[0001] This utility model relates to the field of paper cup and paper bowl production technology, and in particular to a rolling edge heating mechanism. Background Technology

[0002] Paper cups and bowls are widely used in public places, restaurants, and other establishments due to their convenience, safety, and environmental friendliness, for serving hot and cold beverages such as milk tea and coffee. During the manufacturing process of paper cups, the rim is rolled.

[0003] Chinese patent CN202320009500.6 discloses a paper cup edge-rolling device, including a machine base, a turntable for conveying paper cups on the machine base, a placement opening on the turntable, a fixed frame above the turntable, a drive mechanism connected to the fixed frame, a connecting plate connected to the drive mechanism, multiple connecting plates evenly distributed around the circumference, a cylinder on the top of the connecting plate, the output end of the cylinder extending downward and connected to an edge-rolling mold, the edge-rolling mold having an annular groove adapted to the mouth of the paper cup.

[0004] However, existing paper cup edge rolling equipment suffers from poor fit between the cup rim and the edge rolling mold, lack of preheating, or poor heating effect, resulting in unsatisfactory edge rolling forming results. Utility Model Content

[0005] One of the objectives of this utility model is to address the shortcomings of existing technologies by providing a curling edge heating mechanism. This mechanism involves a curling edge mechanism that moves relative to a material-carrying mechanism and a heating mechanism that works in conjunction with it. A semi-finished paper cup is fitted onto the curling edge mechanism. After the heating mechanism softens the cup rim, the curling edge mechanism moves towards the material-carrying mechanism to curl the edge of the cup rim outwards, forming a pre-curled portion. This design ensures good fit between the paper cup rim and the curling edge mechanism, and the independent heating mechanism provides preheating, guaranteeing effective softening and subsequent curling results. This solves the technical problems of poor fit between the paper cup rim and the curling edge mold, lack of preheating or poor heating effect, and unsatisfactory curling edge formation in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A curling heating mechanism includes a base, on which a curling drive mechanism and a heating mechanism are mounted. A curling mechanism is connected to the curling drive mechanism. The mechanism also includes a material loading mechanism positioned opposite the curling mechanism. The curling mechanism is driven by the curling drive mechanism to perform a reciprocating translational movement relative to the material loading mechanism. A semi-finished paper cup is loaded on the material loading mechanism. The semi-finished paper cup is fitted onto the curling mechanism with its rim. After the heating mechanism heats and softens the rim of the semi-finished paper cup, the curling mechanism moves towards the material loading mechanism to curl the rim edge outward, forming a pre-curled portion.

[0008] As an improvement, the edge-rolling mechanism includes a sleeve portion, the front side of which has an annular sleeve interface. The semi-finished paper cup is sleeved on the sleeve interface, and the end of the sleeve interface has an arc-shaped edge-rolling groove. The mouth of the semi-finished paper cup abuts against the edge of the edge-rolling groove, and when the two move relative to each other, the mouth of the cup is guided by the shape of the edge-rolling groove and gradually rolls outward.

[0009] As an improvement, the inner ring of the socket is provided with a support ring wall that guides and supports the inner wall of the cup mouth of the semi-finished paper cup. The support ring wall is connected to the inner diameter edge of the curling groove, and the two cooperate to guide the cup mouth to curl.

[0010] As an improvement, the edge-rolling mechanism also includes a heating section, which covers the sleeve portion from the rear and forms a heating cavity that communicates with the heating mechanism. The outer ring of the sleeve portion is provided with air holes that match the position of the sleeve interface. Hot air is delivered from the heating mechanism and output through the heating cavity and air holes to heat the mouth of the semi-finished paper cup inside the sleeve interface.

[0011] As an improvement, the heating part includes a heating cover with an outer diameter slightly larger than that of the sleeve part. The front end of the heating cover is sealed to the front end of the sleeve part, and the rearward extensions of both form a first part of an annular heating cavity. The heating part also includes a docking cover, which is connected between the rear end of the heating cover and the output end of the heating mechanism. The docking cover is hollow to form a second part of the heating cavity.

[0012] As an improvement, the heating mechanism is connected to the edge-rolling mechanism, and includes an airflow channel directly connected to the edge-rolling mechanism and an air pump connected to the airflow channel.

[0013] As an improvement, the edge-rolling drive mechanism includes a sliding part that is slidably mounted on the base and slides linearly relative to the material loading mechanism. The edge-rolling mechanism is mounted on the sliding part, and the mechanism also includes an edge-rolling drive assembly that drives the sliding part to slide.

[0014] As an improvement, the edge-rolling drive assembly is configured as a cam-driven structure, which includes an edge-rolling drive shaft vertically rotatably mounted on the base. The bottom input end of the edge-rolling drive shaft is connected to an external power source to obtain rotational power, and the top output end is connected to a cam portion. The top surface of the cam portion is recessed with an annular cam groove. The sliding portion includes a protrusion limited within the cam groove. As the cam portion rotates, the protrusion is guided by the trajectory of the cam groove to move back and forth.

[0015] As an improvement, the cam groove is eccentrically arranged relative to the cam section and has a symmetrical structure. It includes a first holding section and a second holding section that are arranged opposite each other with different radii. It also includes two oppositely arranged variable diameter sections. The variable diameter section is connected between the first holding section and the second holding section. When the cam section rotates to the point where its first holding section or second holding section engages with the protrusion, the sliding part remains stationary. When the cam section rotates to the point where its variable diameter section engages with the protrusion, it guides and drives the sliding part to slide linearly.

[0016] As an improvement, the base has three chambers connected sequentially from top to bottom. The sliding part is arranged in the upper chamber, the cam part is arranged in the middle chamber, and the edge-rolling drive shaft is arranged in the lower chamber. The protrusion extends into the middle chamber to cooperate with the cam groove, and the edge-rolling drive shaft extends into the middle chamber to cooperate with the cam part.

[0017] As an improvement, a linear guide rail is provided in the upper cavity, and a slider that is slidably mounted on the linear guide rail is provided at the bottom of the sliding part.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) This utility model sets up a curling mechanism that moves relative to the material loading mechanism and sets up a heating mechanism in conjunction with the curling mechanism. The semi-finished paper cup is fitted onto the curling mechanism. After the heating mechanism heats and softens the cup mouth, the curling mechanism moves towards the material loading mechanism to make the edge of the cup mouth curl outward and form a pre-curled part. The cup mouth of the paper cup and the curling mechanism have a good fit. The independent heating mechanism preheats the cup, thus ensuring effective softening and subsequent curling effect.

[0020] (2) In this utility model, the edge-rolling mechanism is provided with an annular sleeve interface on the sleeve part. The semi-finished paper cup is sleeved on the sleeve interface. An arc-shaped edge-rolling groove is provided at the end of the sleeve interface. The cup mouth is rolled outward under the shape guidance of the edge-rolling groove. In this structure, the sleeve fit between the cup mouth and the edge-rolling mechanism is stable and has a high degree of fit, ensuring that the edge-rolling action is completed stably and effectively. Furthermore, a support ring wall is matched and provided in the inner ring of the sleeve interface. Through the docking fit between the support ring wall and the inner edge of the edge-rolling groove, the inner wall of the cup mouth is supported by the support ring wall. During the relative movement edge-rolling operation, the softened cup mouth can be effectively prevented from collapsing and producing defective products, thereby ensuring that the edge-rolling of the cup mouth is completed smoothly and the edge-rolling quality is guaranteed.

[0021] (3) This utility model heats and softens the cup mouth by setting an independent heating mechanism, which can preheat the cup mouth and then perform relative translation and rolling operations, fully ensuring the softening effect and thus ensuring the success rate of rolling. The sleeve part and the heating part are fitted together to form an annular heating cavity. The outer ring of the sleeve part is provided with air holes that match the position of the sleeve interface, so that the cup wall that needs to be rolled at the cup mouth can be heated fully and effectively, covering a suitable heating range and effectively ensuring the success rate of subsequent rolling.

[0035] Example 1

[0036] like Figure 1-2 As shown, a hemming heating mechanism includes a base 1, on which a hemming drive mechanism 2 and a heating mechanism 3 are mounted. A hemming mechanism 4 is connected to the hemming drive mechanism 2. The mechanism also includes a material loading mechanism 5 positioned opposite the hemming mechanism 4. The hemming mechanism 4 is driven by the hemming drive mechanism 2 to perform a reciprocating translational movement relative to the material loading mechanism 5. Figure 10 As shown, the material loading mechanism 5 is loaded with a semi-finished paper cup 101. The semi-finished paper cup 101 is fitted onto the edge-curling mechanism 4 with its rim. After the heating mechanism 3 heats and softens the rim of the semi-finished paper cup 101, the edge-curling mechanism 4 moves towards the material loading mechanism 5 to cause the edge of the rim to curl outward, forming a pre-curled portion 111. Figure 3 As shown.

[0037] It should be added that, such as Figure 3 As shown, the mouth of the semi-finished paper cup 101 is cylindrical. The purpose of the edge-rolling heating mechanism of this utility model is to make the edge of the mouth of the semi-finished paper cup 101 bend outward to form a pre-rolled edge.

[0038] As an improvement, such as Figure 5-6As shown, the edge-rolling mechanism 4 includes a sleeve part 41. The front side of the sleeve part 41 has an annular sleeve interface 411. The semi-finished paper cup 101 is sleeved on the sleeve interface 411. The end of the sleeve interface 411 has an arc-shaped edge-rolling groove 412. The mouth of the semi-finished paper cup 101 abuts against the edge of the edge-rolling groove 412. When the two move relative to each other, the mouth of the cup is guided by the shape of the edge-rolling groove 412 and gradually rolls outward.

[0039] In this embodiment, an annular socket 411 is provided on the front side of the socket 41, and the semi-finished paper cup 101 is sleeved on the socket 411. An arc-shaped edge-rolling groove 412 is provided at the end of the socket 411. The cup mouth is rolled outward under the shape guidance of the edge-rolling groove 412. In this structure, the socket fit between the cup mouth and the edge-rolling mechanism 4 is stable and has a high degree of fit, ensuring that the edge-rolling action is completed stably and effectively.

[0040] As an improvement, such as Figure 6 As shown, the inner ring of the socket 411 is provided with a support ring wall 413 to guide and support the inner wall of the cup mouth of the semi-finished paper cup 101. The support ring wall 413 is connected to the inner diameter edge of the curling groove 412, and the two cooperate to guide the cup mouth to curl.

[0041] It is worth noting that a support ring wall 413 is further provided on the inner ring of the socket 411. The inner wall of the cup mouth is supported by the support ring wall 413. Through the docking and cooperation between the support ring wall 413 and the inner edge of the edge rolling groove 412, the softened cup mouth can be effectively prevented from collapsing and producing defective products during the relative movement edge rolling operation, so that the edge rolling of the cup mouth can be successfully completed and the edge rolling quality can be guaranteed.

[0042] As an improvement, such as Figure 7-8 As shown, the edge-rolling drive mechanism 2 includes a sliding part 21, which is slidably mounted on the base 1 and slides linearly relative to the material loading mechanism 5. The edge-rolling mechanism 4 is mounted on the sliding part 21, and the edge-rolling drive assembly 22 is also included. The edge-rolling drive assembly 22 drives the sliding part 21 to slide.

[0043] Example 2

[0044] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0045] like Figure 5As shown, as an improvement, the edge-rolling mechanism 4 further includes a heating part 42, which covers the sleeve part 41 from the rear and forms a heating cavity 420 that communicates with the heating mechanism 3. The outer ring of the sleeve part 41 is provided with air holes 414 that match the position of the sleeve interface 411. Hot air is delivered from the heating mechanism 3 and output through the heating cavity 420 and the air holes 414 to heat the mouth of the semi-finished paper cup 101 inside the sleeve interface 411.

[0046] As an improvement, the heating part 42 includes a heating cover 421 with an outer diameter slightly larger than that of the sleeve part 41. The front end of the heating cover 421 is sealed to the front end of the sleeve part 41, and the rearward extensions of both form the first part 4201 of the annular heating cavity 420. The heating part 42 also includes a docking cover 422, which is connected between the rear end of the heating cover 421 and the output end of the heating mechanism 3. The docking cover 422 is hollow to form the second part 4202 of the heating cavity 420.

[0047] As an improvement, such as Figure 2 , 4 As shown in Figures 5 and 6, the heating mechanism 3 is connected to the edge-rolling mechanism 4, and includes an airflow channel 31 that is directly connected to the edge-rolling mechanism 4 and an air pump connected to the airflow channel 31.

[0048] In this embodiment, an independent heating mechanism 3 is set up to heat and soften the cup rim. Compared with the existing technology where the edge rolling mold has a direct heating function, which may result in insufficient softening or a limited softening range, leading to poor edge rolling effect, this embodiment can preheat the cup rim through the heating mechanism 3 and then perform relative translation edge rolling operation, which fully ensures the softening effect and thus ensures the success rate of edge rolling.

[0049] In addition, in this embodiment, the sleeve part 41 and the heating part 42 are fitted together to form an annular heating cavity, and the outer ring of the sleeve part 41 is provided with air holes 414 that match the position of the sleeve interface 411. This can be used to specifically match and fully and effectively heat the cup wall around the rim that needs to be rolled, covering a suitable heating range and effectively ensuring the success rate of subsequent rolling.

[0050] Example 3

[0051] The components in this embodiment that are the same as or corresponding to those in the above embodiments are referred to by the same reference numerals as those in the above embodiments. For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0052] like Figure 7-8As shown, as an improvement, the hemming drive assembly 22 is configured as a cam drive structure, which includes a hemming drive shaft 221 vertically rotatably mounted on the base 1. The bottom input end of the hemming drive shaft 221 is connected to an external power source to obtain rotational power, and the top output end is connected to a cam part 222. The top surface of the cam part 222 is recessed with an annular cam groove 220. The sliding part 21 includes a protrusion 210 limited within the cam groove 220. As the cam part 222 rotates, the protrusion 210 is guided by the trajectory of the cam groove 220 to move back and forth.

[0053] As an improvement, such as Figure 9 As shown, the cam groove 220 is eccentrically arranged relative to the cam portion 222 and has a symmetrical structure. It includes a first retaining section 2201 and a second retaining section 2202 arranged opposite each other with different radii. It also includes two oppositely arranged variable diameter sections 2203. The variable diameter section 2203 is connected between the first retaining section 2201 and the second retaining section 2202. When the cam portion 222 rotates to the point where its first retaining section 2201 or its second retaining section 2202 engages with the protrusion 210, the sliding portion 21 remains stationary. When the cam portion 222 rotates to the point where its variable diameter section 2203 engages with the protrusion 210, it guides and drives the sliding portion 21 to slide linearly.

[0054] In this embodiment, the cam groove 220 is configured as described above so that during the rotation of the cam part 222, the cam groove 220 limits the protrusion 210, thereby driving the sliding part 21 to move back and forth, which can be used to perform continuous assembly line-style edge rolling operations.

[0055] As an improvement, such as Figure 7-8 As shown, the base 1 has three chambers connected sequentially from top to bottom. The sliding part 21 is arranged in the upper chamber 11, the cam part 222 is arranged in the middle chamber 12, and the edge-rolling drive shaft 221 is arranged in the lower chamber 13. The protrusion 210 extends into the middle chamber 12 to cooperate with the cam groove 220, and the edge-rolling drive shaft 221 extends into the middle chamber 12 to cooperate with the cam part 222.

[0056] In this embodiment, the installation layout of the hemming drive mechanism 2 in the base 1 is compact and reasonable. The components are installed in separate chambers and cooperate reasonably, so the driving action is stable and reliable.

[0057] As an improvement, such as Figure 8 As shown, a linear guide rail 112 is provided in the upper chamber 11, and a slider 211 is slidably mounted on the linear guide rail 112 at the bottom of the sliding part 21.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
