[0052] Combine the following Figures 1 to 8 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0053] Figure 1 It is a schematic diagram of the overall structure of the automatic tin foil cup forming device provided by the embodiment of the utility model; Figure 2 A schematic structural diagram of a mold sleeve assembly provided by an embodiment of the utility model; Figure 3 The utility model is a schematic diagram of the cross-sectional structure of the automatic tin foil cup forming device provided in the embodiment of the utility model.

[0054] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model provides an automatic forming device for tin foil cups, hereinafter referred to as a forming device, and the forming device includes a conveying component 100, a mold sleeve component 200 and a pressing sleeve component 300; the conveying component 100 is used to transport the tin foil 10 to a preset position. It should be noted that the preset position is the position where the mold sleeve component 200 and the pressing sleeve component 300 are docked during operation.

[0055] The mold sleeve assembly 200 is located below the tin foil 10. The mold sleeve assembly 200 has a molding cavity 223 and a cutting portion 224. The mold sleeve assembly 200 has an opening on one side facing the tin foil 10, and the opening is connected to the molding cavity 223. The cutting portion 224 and the opening are arranged on the same side of the mold sleeve assembly 200. The pressing sleeve assembly 300 is located above the tin foil 10 and corresponds to the position of the mold sleeve assembly 200. The pressing sleeve assembly 300 is used to press the tin foil 10 into the molding cavity 223 from the opening to form the tin foil cup 20.

[0056] It should be noted that the shape of the tin foil cup 20 is related to the shape of the forming cavity 223 and the shape of the pressing sleeve assembly 300. When it is necessary to make tin foil cups 20 of different specifications, the shape of the forming cavity 223 and the shape of the pressing sleeve assembly 300 can be pre-designed. Specifically, adaptive design can be performed according to the needs, and the utility model will not elaborate on this. Among them, when the pressing sleeve assembly 300 presses the tin foil 10 downward, the cutting portion 224 is suitable for piercing the tin foil 10 from bottom to top, and the cutting portion 224 is used to cut and position the tin foil 10.

[0057] See also Figure 1 , Figure 2 and Figure 3 It can be understood that the automatic tin foil cup forming device provided by the embodiment of the utility model can efficiently and continuously produce tin foil cups 20 with uniform shape, low cost, no need for human intervention, and can cooperate with mechanical grippers to achieve true automation. Based on this, while improving production efficiency, it can also reduce production costs and improve economy.

[0058] In addition, in the process of the pressing sleeve assembly 300 pressing the tin foil 10 into the forming cavity 223, because it is impossible to absolutely ensure that the contact surface between the pressing sleeve assembly 300 and the mold sleeve assembly 200 is completely fitted, it is easy to cause the tin foil 10 to be affected by the pressing sleeve assembly 300 and cause displacement. The automatic tin foil cup forming device provided by the embodiment of the utility model is provided with a cutting portion 224 on the opening side of the mold sleeve assembly 200, and the tin foil 10 is first pierced and then cut by the cutting portion 224. It is easy to understand that since the cutting portion 224 is provided on the mold sleeve assembly 2 00, the mold sleeve assembly 200 itself is fixed, so that the tin foil 10 can be positioned while cutting the tin foil 10. In other words, the cutting portion 224 can provide the tin foil 10 with multiple anchoring points when cutting the tin foil 10. In this way, when the pressing sleeve assembly 300 presses the tin foil 10 into the molding cavity 223, the tin foil 10 will not be easily deviated by the pressing sleeve assembly 300, which can make the cutting process smoother, improve the success rate and yield rate of the molding of the tin foil cup 20, and ensure that the subsequent processes are carried out more smoothly.

[0059] Compared with the prior art, the automatic tin foil cup forming device provided in the embodiment of the utility model pierces the tin foil 10 first and then cuts it through the cutting part 224, so that the cut tin foil 10 can be positioned while cutting the tin foil 10, which can avoid the displacement problem of the tin foil 10 driven by the pressing sleeve assembly 300, reduce the phenomenon of failure in forming the tin foil cup 20 due to such problem, and improve the yield rate of the tin foil cup 20.

[0060] Figure 4 This is a schematic diagram of the structure of the support provided by the embodiment of the utility model; Figure 5 It is a structural schematic diagram of a mold sleeve provided in an embodiment of the utility model.

[0061] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 In an optional embodiment of the utility model, the mold sleeve assembly 200 includes a support 210 and a mold sleeve 220 of a preset shape, wherein the support 210 is fixedly mounted on the conveying assembly 100 and is located below the tin foil 10, and the support 210 is a hollow structure for mounting the mold sleeve 220, such as Figure 4 As shown, in the embodiment of the utility model, the support 210 is a hollow cube, and the upper, lower, left and right sides of the support 210 are provided with openings connected to the hollow structure, wherein the openings on the upper and lower surfaces are adapted to the structure of the mold sleeve 220 for installing the mold sleeve 220. The specific structure of the support 210 can be adaptively designed according to actual needs, and the embodiment of the utility model will not go into details about this.

[0062] The mold sleeve 220 is disposed in the support 210. Figure 2 , Figure 3 and Figure 5 In the embodiment of the utility model, the mold sleeve 220 includes a body 221 and a base 222. The body 221 is a hollow structure, and both the upper and lower ends are open structures. The body 221 is arranged on the support 210, and the base 222 is arranged at the lower end of the body 221, that is, at the opening of the lower end of the body 221. The base 222 and the body 221 surround the aforementioned molding cavity 223. The base 222 and the body 221 are slidably matched, and the base 222 can reciprocate along the length direction of the molding cavity 223. The cutting part 224 and the aforementioned opening for the pressing sleeve assembly 300 to press the tin foil 10 into the molding cavity 223 are both arranged on the side of the body 221 away from the base 222. In some other optional examples of the utility model, the lower end of the body 221 may not be provided with an opening, that is, the lower end of the body 221 is in a closed state. Specifically, it can be adaptively set according to actual conditions.

[0063] Figure 6 yes Figure 5 Schematic diagram of the local enlarged structure at point A in the middle.

[0064] See also Figure 5 and Figure 6 The cutting portion 224 includes a plurality of spikes 2241, which are arranged around the side opening. The spikes 2241 are suitable for piercing the tin foil 10 from bottom to top. It can be understood that in the process of the pressing sleeve assembly 300 pressing the tin foil 10 into the molding cavity 223, the tin foil 10 will first contact the spikes 2241 of the cutting portion 224. After the plurality of spikes 2241 pierce the tin foil 10, since the spikes 2241 and the mold sleeve 220 are fixed, the tin foil 10 can be positioned while cutting the tin foil 10, that is, the plurality of spikes 2241 can provide the tin foil 10 with a plurality of anchoring points. In this way, when the pressing sleeve assembly 300 presses the tin foil 10 into the molding cavity 223, the tin foil 10 will not be deviated by the pressing sleeve assembly 300, which can make the cutting process smoother, improve the yield rate of the tin foil cup 20 and the success rate of molding, and ensure that the subsequent processes are carried out more smoothly.

[0065] Continue reading Figure 6 In an optional embodiment of the utility model, the inner and outer surfaces of the spike 2241 are both provided with circular chamfers. In other words, the inner and outer surfaces of the spike 2241 are both inclined surfaces. This can, on the one hand, facilitate the spike 2241 to pierce the tin foil 10; on the other hand, during the sliding process of the tin foil cup 20 being formed, the tin foil 10 will not be caught by the spike 2241, which can improve the success rate of the forming of the tin foil cup 20.

[0066] Continue reading Figure 2 and Figure 3In an optional embodiment of the utility model, the mold sleeve assembly 200 also includes a demolding component 230, which is arranged at the lower end of the base 222 and connected to the base 222. Specifically, the demolding component 230 includes a cylinder and a push rod, the piston rod of the cylinder is fixedly connected to the push rod, and the end of the push rod away from the piston rod is connected to the base 222. In this way, when the piston rod in the cylinder performs reciprocating linear motion, the piston rod can drive the push rod to perform synchronous reciprocating linear motion, and then the base 222 connected to the push rod can perform reciprocating linear motion in the molding cavity 223. It can be understood that the demolding component 230 is used to drive the base 222 to perform reciprocating linear motion along the molding cavity 223, so that the molded tin foil cup 20 can be ejected from the mold sleeve 220 to facilitate the removal and transfer of the tin foil cup 20.

[0067] Continue reading Figure 2 In an optional embodiment of the utility model, the upper surface of the base 222, that is, the surface in contact with the tin foil cup 20, is provided with a groove, and the shape of the groove is adapted to the shape of the bottom of the tin foil cup 20. In this way, during the process of the tin foil cup 20 being ejected, the stability of the tin foil cup 20 can be ensured, and the tin foil cup 20 can be prevented from tilting or shifting during the ejection process.

[0068] Figure 7 It is a structural schematic diagram of a pressing sleeve assembly provided in an embodiment of the utility model.

[0069] See also Figure 7 In an optional embodiment of the utility model, the pressing sleeve assembly 300 includes a driving component 310 and a pressing sleeve component 320, wherein the driving component 310 includes a lead screw, a lead screw motor, a guide rail and a slider, the guide rail is fixedly mounted on the conveying component 100, the lead screw and the guide rail are arranged in parallel and spaced apart, and the lead screw is arranged on the side of the guide rail close to the conveying component 100; the slider is sleeved on the lead screw and cooperates with the lead screw for rotation, and the slider is also slidably connected to the lead screw, the lead screw motor is arranged at one end of the lead screw, and the lead screw motor is used to drive the lead screw to rotate. It can be understood that when the lead screw rotates, due to the restriction of the guide rail on the slider, the slider will not rotate with the rotation of the lead screw, and the slider will move linearly along the length direction of the lead screw.

[0070] Continue reading Figure 3 The pressing sleeve component 320 is located above the tinfoil 10 and corresponds to the mold sleeve assembly 200. The pressing sleeve component 320 is connected to the slider. In other words, the pressing sleeve component 320 is connected to the output end of the driving component 310. It can be understood that when the slider performs reciprocating linear motion along the lead screw, the pressing sleeve component 320 will also perform reciprocating linear motion accordingly. In this way, when the pressing sleeve component 320 moves to contact the tinfoil 10, the pressing sleeve component 320 can continue to move downward with the tinfoil 10, that is, the tinfoil 10 can be pressed into the molding cavity 223 of the mold sleeve assembly 200, thereby realizing the molding of the tinfoil cup 20.

[0071] It should be noted that, in some other optional examples, the driving component 310 can be replaced by other devices capable of linear driving, such as piston cylinders or linear motors. Specifically, it can be adaptively configured according to actual conditions.

[0072] Figure 8 It is a schematic cross-sectional structure diagram of a pressing sleeve component provided in an embodiment of the utility model.

[0073] See also Figure 8 In an optional embodiment of the utility model, the pressing sleeve component 320 includes a main pressing sleeve 322 and an auxiliary pressing sleeve 323, and the main pressing sleeve 322 includes a mold cone 321, a main pressing sleeve 322 and an auxiliary pressing sleeve 323, wherein the shape of the mold cone 321 is adapted to the shape of the tin foil cup 20 to be manufactured, that is, the mold cone 321 matches the molding cavity 223, so that Figure 8 For example, in this example, the tinfoil cup 20 to be manufactured is conical, so the mold cone 321 and the molding cavity 223 can also be set to be conical. It can be understood that when the mold cone 321 presses the tinfoil 10 into the molding cavity 223, the tinfoil 10 can change its shape and be shaped by itself under the bidirectional extrusion of the mold cone 321 and the inner wall of the molding cavity 223 to form the tinfoil cup 20.

[0074] The main pressure sleeve 322 is sleeved on the outside of the mold cone 321 and is fixedly connected to the output end of the driving component 310, that is, it is fixedly connected to the aforementioned slider. The main pressure sleeve 322 is adapted to the cutting part 224. Under the drive of the driving component 310, the main pressure sleeve 322 can press the tin foil 10 on the cutting part 224 and assist the cutting part 224 to puncture the tin foil 10. In other words, the main pressure sleeve 322 can assist the cutting part 224 to cut and position the tin foil 10.

[0075] The auxiliary pressure sleeve 323 is suspended on the shoulder of the main pressure sleeve 322 and slidably cooperates with the main pressure sleeve 322, and the auxiliary pressure sleeve 323 is longer in the axial direction than the main pressure sleeve 322. Specifically, when the pressure sleeve component 320 is at the top of the screw, the auxiliary pressure sleeve 323 will be suspended on the shoulder of the main pressure sleeve 322 due to its own weight; when the pressure sleeve component 320 moves downward and contacts the tin foil 10, since there is a certain distance difference between the lower end surface of the auxiliary pressure sleeve 323 and the lower end surface of the main pressure sleeve 322, the auxiliary pressure sleeve 323 can press the tin foil 10 downward first, and then the auxiliary pressure sleeve 323 and the mold sleeve assembly 200 are in contact. When the support 210 is abutted, the tinfoil 10 will be first fixed on the upper surface of the support 210 by the auxiliary pressure sleeve 323. Since the auxiliary pressure sleeve 323 and the main pressure sleeve 322 are slidably matched, the main pressure sleeve 322 can continue to press downward to position and cut the tinfoil 10. It can be understood that by setting the auxiliary pressure sleeve 323, the tinfoil 10 can be positioned before being cut. In this way, the accuracy of the position of the tinfoil 10 can be improved, the cutting process can be made smoother, the yield rate of the tinfoil cup 20 and the success rate of molding can be improved, and the subsequent processes can be ensured to proceed more smoothly.

[0076] Continue reading Figure 3 In an optional embodiment of the utility model, the conveying assembly 100 includes a supporting component 110, a conveying motor 120, a storage wheel 130, a driving wheel 140 and a traction wheel 150, wherein the supporting component 110 includes a first side plate and a second side plate, and the first side plate and the second side plate are arranged opposite to each other for supporting the forming device. Specifically, the die sleeve assembly 200 is arranged between the first side plate and the second side plate, and the pressing sleeve assembly 300 is arranged on the side of the first side plate away from the die sleeve assembly 200. The connection between the first side plate and the second side plate and the die sleeve assembly 200 and the pressing sleeve assembly 300 can be achieved by fastener connection or welding, etc. There are many connection methods, which will not be described one by one in this article.

[0077] The storage wheel 130 is arranged at one end of the supporting component 110, that is, at one end of the first side plate and the second side plate. The two ends of the storage wheel 130 are respectively arranged in the limiting grooves of the first side plate and the second side plate. It should be noted that an opening is provided at the upper end of the limiting groove, so that it is convenient to take and place the storage wheel 130. The storage wheel 130 is wrapped with tinfoil 10. In other words, the storage wheel 130 is used to set the tinfoil roll.

[0078] The driving wheel 140 is arranged at the other end of the supporting component 110, that is, at the other end of the first side plate and the second side plate. The conveying motor 120 and the driving wheel 140 are arranged at the same end of the first side plate. At the same time, the output end of the conveying motor 120 is connected to the driving wheel 140. The driving wheel 140 is suitable for rotating around its own axis under the drive of the conveying motor 120. The traction wheel 150 and the driving wheel 140 are arranged at the same end of the supporting component 110, that is, at the other end of the first side plate and the second side plate. The traction wheel 150 and the driving wheel 140 are opposite and abutted. The tinfoil 10 is located between the traction wheel 150 and the driving wheel 140. The traction wheel 150 is suitable for cooperating with the driving wheel 140 to pull the tinfoil 10 by rolling and squeezing, so that the tinfoil 10 located between the traction wheel 150 and the storage wheel 130 has tension. It can be understood that by pulling the tinfoil 10 by rolling, the traction of the tinfoil 10 can be smoother. This arrangement is also convenient for the replacement of the traction wheel 150, which is beneficial to the maintenance of the traction wheel 150 and the driving wheel 140. Compared with collecting the used tinfoil 10 by the driving wheel 140, this arrangement can avoid the step of replacing the driving wheel 140, and can improve the overall efficiency of the production of the tinfoil cup 20.

[0079] Continue reading Figure 3 In an optional embodiment of the utility model, the conveying assembly 100 also includes a first guide rod 160 and a second guide rod 170. The first guide rod 160 and the storage wheel 130 are arranged at the same end of the support component 110, and the first guide rod 160 and the support component 110 are rotatably matched; the second guide rod 170 and the driving wheel 140 are arranged at the same end of the support component 110, and the second guide rod 170 is also rotatably matched with the support component 110; during assembly, the end of the tin foil 10 from the storage wheel 130 can first bypass the first guide rod 160 and then be pulled to the second guide rod 170, and the tin foil 10 can be made to bypass the second guide rod 170 and then pass through the rolling and extrusion area between the driving wheel 140 and the traction wheel 150.

[0080] In this embodiment, the horizontal plane where the second guide rod 170 is located is higher than the horizontal plane where the first guide rod 160 is located and the upper surface of the mold sleeve assembly 200. It can be understood that a portion of the tin foil 10 will be lost after being cut, which will cause the toughness of the tin foil 10 to decrease. Through such a setting, the tin foil 10 located between the first guide rod 160 and the second guide rod 170 can be set in an inclined surface, and there is a certain gap between the inclined surface and the upper surface of the mold sleeve assembly 200. In this way, the tin foil 10 can be ensured to be more stable when being pulled and not easily torn, which is beneficial to improving the stability of the tin foil 10.

[0081] Continue reading Figure 1In an optional embodiment of the utility model, the automatic tin foil cup forming device also includes a detection component 400, which is arranged on the second side plate of the conveying component 100, and the detection component 400 is used to detect the overall height of the tin foil cup 20 after forming to identify defective tin foil cups 20. In an optional embodiment of the utility model, the detection component 400 includes a bracket, a transverse moving component 410 and a detector 420. The bracket is arranged on the conveying component 100, the transverse moving component 410 is arranged on the bracket, and the detector 420 is arranged on the transverse moving component 410 and connected to the output end of the transverse moving component 410. The detector 420 is suitable for reciprocating linear motion along the moving direction of the tinfoil 10 with the transverse moving component 410. At the same time, the emitting end of the detector 420 faces the tinfoil cup 20 and is slightly higher than the theoretical forming height of the tinfoil cup 20. It can be understood that each time the tinfoil is cut, it is a circle with the same diameter. When the tinfoil cup 20 is formed, if the tinfoil 10 is offset, it will inevitably cause the tinfoil cup 20 to be high on one side and low on the other side, and the high side must be greater than the height of the qualified tinfoil cup 20, that is, greater than the theoretical forming height of the tinfoil cup 20. When the detector 420 moves laterally, the detection light emitted by the detector 420 sweeps over the top of the tinfoil cup 20. When the height of a certain position of the tinfoil cup 20 is higher than the theoretical forming height, the position of the tinfoil cup 20 that exceeds the theoretical forming height will inevitably be detected by the detection light. The detector 420 can identify the defective tinfoil cup 20 based on the data fed back by the detection light.

[0082] Continue reading Figure 1 In an optional embodiment of the utility model, the automatic forming device of the tin foil cup 20 further includes a monitoring component, which is arranged below the tin foil paper 10 and is located on the side of the mold sleeve component 200 facing the storage wheel 130. The specific structure of the monitoring component is similar to the detection component 400 and will not be repeated here. The difference is that the monitoring light beam of the monitoring component is from bottom to top toward the tin foil paper 10 to be processed above. It can be understood that by setting up the monitoring component, it is possible to monitor in real time whether there is tin foil paper 10 to be processed, which helps to improve the automation of the forming device.

[0083] The working process of the automatic tin foil cup forming device in the embodiment of the utility model is shown below:

[0084] Preparation state: the pressing component 320 is at the top of the driving component 310, the base 222 is located at the bottom of the molding cavity 223, and the tin foil 10 to be processed is transported to a preset position by the conveying component 100.

[0085] Forming process: the pressing sleeve component 320 moves downward with the driving component 310 and presses the tin foil 10 downward; the auxiliary pressing sleeve 323 first presses the tin foil 10 onto the support 210, and the main pressing sleeve 322 moves further downward and presses the tin foil 10 to the cutting part 224, and the cutting part 224 punctures, locates and cuts the tin foil 10; the mold cone 321 moves further downward to press the tin foil 10 to the deepest part of the molding cavity 223, waiting for the tin foil cup 20 to be finalized; the pressing sleeve component 320 moves upward, and the demolding component 230 pushes the tin foil cup 20 out through the base 222, the transfer mechanism moves out the tin foil cup 20, and the conveying component 100 runs to pull away the cut tin foil 10 and transport the tin foil 10 to be processed to the preset position. Through the device cycle in this way, the automatic forming of the tin foil cup 10 can be completed.
