Description

Technical Field

[0001] The utility model relates to the technical field of paper cup bottom sealing, in particular to a popcorn bucket bottom sealing device. Background Art

[0002] A popcorn bucket is generally made of paper cups. The circular paper piece used in the production of the paper cup bottom seal needs to be embossed with a groove on the outer surface of the paper piece in order to make the circular cup bottom paper piece fit with the bottom of the paper cup, so that the outer edge of the circular paper piece can be folded and matched at the bottom of the paper cup to form a seal. The traditional bonding structure of the cup body and the cup bottom on the market is to put the formed cup body on the paper cup mold through the upper cup component, and then the paper cup mold will send the formed cup body to the cup bottom punching component, and the cup bottom punching component will send the stamped cup bottom to the bottom position of the cup body. Solid glue is pre-set at the bottom of the cup body. When the cup bottom punching component sends the cup bottom to the bottom position of the cup body, the cup bottom and the cup body are bonded and fixed by the solid glue, and then the paper cup mold drives the cup body and the cup bottom to the heating component so that the solid glue at the bottom of the cup body melts and bonds with the cup bottom.

[0003] The defects of the above cup bottom bonding structure are: 1. The existing equipment has the problem of insufficient processing of the cup body assembly position. The cup body is prone to deviation during the process of pressing into the cup sleeve, which can easily lead to the failure of the cup body and the cup bottom to seal, resulting in defective products. 2. Since the bottom of the cup body is pre-set with solid glue, the adhesion between it and the cup bottom is poor. Under the condition of poor adhesion, the cup bottom is easy to separate from the cup body during the heating process brought into the heating assembly by the paper cup mold, resulting in the scrapping of the cup, which is in urgent need of improvement.

[0035] Popcorn buckets are generally made of paper cups. In order to make the circular paper sheet used in the production of the paper cup bottom cover fit with the bottom of the paper cup, it is necessary to emboss a groove on the outer surface of the paper sheet to facilitate the outer edge of the circular paper sheet to fold and fit at the bottom of the paper cup to form a seal.

[0036] The defects of the above cup bottom bonding structure are: 1. The existing equipment has the problem of insufficient processing of the cup body assembly position. The cup body is prone to deviation during the process of pressing into the cup sleeve, which can easily lead to the failure of the cup body and the cup bottom to seal, resulting in defective products. 2. Since the bottom of the cup body is pre-set with solid glue, the adhesion between it and the cup bottom is poor. Under the condition of poor adhesion, the cup bottom is easy to separate from the cup body during the heating process brought into the heating assembly by the paper cup mold, resulting in the scrapping of the cup, which is in urgent need of improvement.

[0037] Based on this, the technical problems existing in the related art, such as insufficient processing of the cup body assembly position of the existing equipment and easy falling off of the cup bottom, can be improved, and the embodiments of the present application provide the following solutions.

[0038] Please read Figures 1 to 5 The embodiment of the present application provides a popcorn bucket bottom sealing device, including a frame 10, a conveying assembly 20, a positioning assembly 30, a stamping assembly 40, a heating assembly 50 and a bottom sealing assembly 60; the conveying assembly 20 includes a turntable 21 arranged on the frame 10, a plurality of cup sleeves 22 mounted on the turntable 21 and a limiting ring 23 sleeved on the fixed end of the cup sleeve 22;

[0039] The positioning assembly 30 includes a first driving member 31 and a limiting plate 32, and the limiting plate 32 is slidably mounted on the frame 10 through the first driving member 31;

[0040] The punching assembly 40 includes a punching plate 41 for punching the cup bottom, a punching ring 42 and a second driving member 43. The punching plate 41 is mounted on the frame 10. The punching ring 42 is slidably mounted on the frame 10 through the second driving member 43. A clearance hole 411 is opened on the punching plate 41.

[0041] The heating assembly 50 includes a fixing block 53 and an annular heating tube 51, and the heating tube is arranged on the stamping plate 41 through the fixing block 53;

[0042] The bottom sealing assembly 60 is used to push the punched cup bottom to the bottom of the cup body.

[0043] As can be seen from the above, the bottom sealing device of a popcorn bucket provided in the embodiment of the present application, when sealing the bottom, first coats the bottom of the cup body with hot melt adhesive, starts the turntable 21, and when the cup body on the cup sleeve 22 is transferred to the limiting plate 32, starts the first driving member 31 to drive the limiting plate 32 to move in the direction close to the turntable 21 until the cup body contacts the limiting ring 23, thereby achieving the effect of limiting the cup body and completing the assembly position adjustment of the cup body in the cup sleeve 22; when the cup body is transferred to the position of the raw material of the cup bottom, starts the annular heating tube 51 to heat and melt the hot melt adhesive, and the second driving member 43 pushes the stamping ring 42, which stamps the raw material of the cup bottom and presses the raw material of the cup bottom against the stamping plate 41. After the formed cup bottom is stamped out from the raw material of the cup bottom, the bottom sealing assembly 60 pushes the formed cup bottom out of the clearance hole 411 The bottom of the cup is heat-sealed on the cup body. The stamping component 40, the abutment ring and the bottom sealing component 60 are used in combination to directly heat-seal the stamped bottom of the cup to the bottom of the cup body, reducing the possibility of the bottom of the cup falling from the bottom of the cup body during transportation, thereby increasing the qualified rate of the bottom sealing of the paper cup; therefore, the first driving member 31, the limiting plate 32 and the limiting ring 23 are set. By starting the first driving member 31, the limiting ring 23 cooperates with the limiting plate 32 to press the dislocated cup body back into the positioning cup sleeve 22, and press the cup body into the correct assembly position in the cup sleeve 22, thereby reducing the probability of defective products; the setting of the annular heating tube 51 enables the solid glue at the bottom of the cup body to be liquefied through the annular heating tube 51 when the cup body enters the raw material position of the cup bottom, so as to improve the adhesion of the cup bottom to the cup body and improve the production quality of the cup.

[0044] Optionally, in some embodiments, see Figures 1 to 3 The frame 10 is provided with a motor 24 for driving the turntable 21 to rotate.

[0045] With such arrangement, when the cup body needs to be transported, the motor 24 is started, the turntable 21 rotates, and the cup body on the cup sleeve 22 is first adjusted in position by the positioning assembly 30. When it moves to the stamping plate 41, the heating assembly 50 is started to hot-melt the colloid on the cup body; the stamping ring 42 stamps the raw material of the cup bottom and presses the raw material of the cup bottom against the stamping plate 41. After the formed cup bottom is stamped out from the raw material of the cup bottom, the bottom sealing assembly 60 pushes the formed cup bottom out of the clearance hole 411 and heat-seals the cup bottom on the cup body; therefore, the arrangement of the motor 24 makes it convenient for the staff to control the rotation of the turntable 21.

[0046] Optionally, in some embodiments, see Figure 4 The end of the stamping ring 42 close to the second driving member 43 is connected to a sliding seat 44, and the sliding seat 44 is slidably installed on the frame 10, and the output end of the second driving member 43 is connected to the sliding seat 44; the bottom cover assembly 60 includes a bottom cover driving member 61 and a bottom cover member 62, and the bottom cover drive is arranged on the sliding seat 44, and the bottom cover member 62 is connected to the bottom cover driving member 61, and the bottom cover drive is used to push the bottom cover member 62 and the stamped cup bottom to fit with the bottom of the cup body, and the bottom cover member 62 is coaxially arranged in the stamping ring 42.

[0047] With such arrangement, when the bottom sealing operation is performed on the cup body, the second driving member 43 is started to push the stamping ring 42 to stamp the raw material of the cup bottom, and the raw material of the cup bottom is pressed tightly against the stamping plate 41. After the formed cup bottom is stamped out from the raw material of the cup bottom, the bottom sealing driving member 61 is started; the bottom sealing member 62 is made to slide toward the stamping plate 41, and the cup bottom is pushed out of the clearance hole 411, and the cup bottom is heat-sealed on the cup body. Therefore, the arrangement of the sliding seat 44 makes it convenient for the second driving member 43 to control the sliding position of the stamping ring 42, and at the same time, the bottom sealing driving member 61 can control the sliding position of the bottom sealing member 62 arranged in the stamping ring 42, so as to facilitate the equipment to perform the bottom sealing operation on the cup body.

[0048] Optionally, in some embodiments, please read Figures 4 to 5 The annular heating tube 51 is provided with a receiving cavity 511 , and a central heating wire 512 is provided in the receiving cavity 511 .

[0049] With such arrangement, when the cup body is conveyed to the position of the raw material of the cup bottom, the central heating wire 512 is started to heat and melt the hot melt adhesive adhered to the cup body, the second driving member 43 is started to push the stamping ring 42 to stamp the raw material of the cup bottom, and the raw material of the cup bottom is pressed tightly against the stamping plate 41. After the formed cup bottom is stamped out from the raw material of the cup bottom, the bottom sealing assembly 60 pushes the formed cup bottom out of the clearance hole 411 and heat-seals the cup bottom on the cup body; the heating wire is a filamentary element that converts electrical energy into thermal energy, and is usually made of metal wire or alloy wire, can withstand high temperatures and has a certain degree of corrosion resistance. The advantages of the heating wire include low production cost, long service life, fast heating speed and high efficiency; it can be used to timely heat the hot melt adhesive adhered to the cup body, and the operation is simple and convenient.

[0050] Optionally, in some embodiments, see Figure 3 A heat-conductive silicone layer 513 is disposed in the receiving cavity 511 , a heat-conductive filler 514 is wrapped in the heat-conductive silicone layer 513 , the central heating wire 512 is disposed in the heat-conductive filler 514 , and the heat-conductive silicone layer 513 is attached to the inner tube wall of the annular heating tube 51 .

[0051] In this way, the setting of the thermally conductive filler 514 provides the annular heating tube 51 with good thermal conductivity, which is convenient for the annular heating tube 51 to heat and melt the hot melt adhesive; since the thermally conductive silicone layer 513 is an elastic material, when the tube wall of the annular heating tube 51 partially cracks due to thermal expansion, the thermally conductive silicone layer 513 will not break, and the thermally conductive silicone layer 513 wraps the thermally conductive filler 514, and the thermally conductive filler 514 will not leak out; secondly, since the thermally conductive silicone layer 513 is attached to the inner tube wall of the annular heating tube 51, the fragments generated when the tube wall of the annular heating tube 51 cracks are not easy to scatter or splash; the setting of the thermally conductive silicone layer 513 not only provides the annular heating tube 51 with good thermal conductivity, but also significantly improves the safety performance of the annular heating tube 51.

[0052] Optionally, in some embodiments, see Figures 4 to 5 A heating cover 52 is provided on the stamping plate 41 , and the heating cover 52 is provided on the outside of the annular heating tube 51 . An opening 521 is provided on one side of the heating cover 52 close to the clearance hole 411 .

[0053] With such arrangement, when the annular heating tube 51 is started, the emitted heat will be concentrated at the opening 521 to heat the cup body moved to the stamping plate 41; therefore, the heating cover 52 has the function of gathering heat, and the heating cover 52 can effectively isolate the annular heating tube 51 from the erosion of dust and oil, so that the annular heating tube 51 can be kept clean and intact for a long time.

[0054] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
