Description

Technical Field

[0002] In a thermoforming production line, in order to improve the conveying accuracy of the film material, piercing parts are set on the conveyor chain.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figures 1 to 7 The feeding module of the first aspect of this application will be described in detail.

[0024] refer to Figure 1 , Figure 5 and Figure 6 According to an embodiment of the present invention, the feeding module includes a conveying mechanism 100 and a heating mechanism 200. The conveying mechanism 100 includes a mounting frame 110, a conveying chain 120, and a driving structure 130. A conveying line 110a is formed on the mounting frame 110. The conveying chain 120 is wound around the mounting frame 110. A plurality of piercing parts 121 are provided at intervals along its own length direction on the conveying chain 120. The piercing parts 121 are used to pierce the edge of the film material. The driving structure 130 is drivenly connected to the conveying chain 120. Under the drive of the driving structure 130, the conveying chain 120 can drive the film material to move along the conveying line 110a. The heating mechanism 200 is located on one side of the beginning of the conveying line 110a. The heating mechanism 200 is used to heat and soften the film material to be entered into the conveying line 110a.

[0025] For example, such as Figure 1 , Figure 5 and Figure 6 As shown, the feeding module includes a conveying mechanism 100 and a heating mechanism 200. The heating mechanism 200 is located in front of the conveying mechanism 100. The conveying mechanism 100 includes a mounting frame 110, a conveying chain 120 and a drive structure 130. The mounting frame 110 is provided with a conveying line 110a extending forward and backward. The conveying chain 120 is wound around the mounting frame 110. The conveying chain 120 is provided with a plurality of piercing parts 121 spaced apart along its own length direction. The drive structure 130 is provided on the mounting frame 110 and is connected to the conveying chain 120 for transmission.

[0026] Furthermore, when the feeding module of this application is working, the film material enters the beginning of the conveyor line 110a after passing through the heating mechanism 200. The drive structure 130 drives the conveyor chain 120 to move along the conveyor line 110a, so that the piercing part 121 on the conveyor chain 120 pierces the edge of the film material in the width direction. Thus, the conveyor chain 120 can drive the film material to move along the conveyor line 110a. At the same time, as subsequent film materials enter the beginning of the conveyor line 110a, other piercing parts on the conveyor chain 120 can continue to pierce the film material. At the end of the conveyor line 110a, the piercing part on the conveyor chain 120 will detach from the film material. When the piercing part moves to the beginning of the conveyor line 110a, it will pierce the film material located at the beginning of the conveyor line 110a again, so that the feeding module can continuously convey the film material to move along the conveyor line 110a.

[0027] It is understood that in the feeding module of this application, by setting a heating mechanism 200, the heating mechanism 200 can heat and soften the film material before the piercing part 121 on the conveyor chain 120 pierces the film material. After the film material is softened, on the one hand, the piercing part 121 can pierce the film material more easily, and on the other hand, the stress generated inside the film material is smaller when the piercing part 121 pierces the film material, thereby reducing the probability of cracks on the film material. During the subsequent conveying of the film material along the conveyor line 110a, the film material will gradually cool and harden, so that the subsequent punching module can normally complete the punching process of the film material.

[0028] In some embodiments of this utility model, the heating mechanism 200 includes a mounting base 210 and two limiting seats 220. The two limiting seats 220 are distributed at intervals along the width direction of the conveyor line 110a. Each of the two limiting seats 220 has a guide groove 221 at one end that is close to each other. The guide groove 221 allows one end of the film material in the width direction to extend into it and is used to guide the film material to move towards the beginning of the conveyor line 110a. A heating element 222 is provided inside the limiting seat 220. The heating element 222 is used to heat and soften the film material.

[0029] For example, such as Figure 2 and Figure 3 As shown, the heating mechanism 200 includes a mounting base 210 and two limiting seats 220. The two limiting seats 220 are distributed on the mounting base 210 at intervals in the left and right direction. Each of the two limiting seats 220 has a guide groove 221 extending forward and backward at one end that is close to each other, and each of the two limiting seats 220 has a heating element 222 inside.

[0030] Furthermore, when the feeding module of this application is working, the left and right ends of the film material can be respectively inserted into the guide grooves 221 of the two limiting seats 220, and the film material can move from front to back along the guide grooves 221. During the movement of the film material along the guide grooves 221, the heating element 222 in the limiting seat 220 can heat and soften the part of the film material located in the guide grooves 221, so that after the film material enters the conveyor line 110a, the piercing part 121 on the conveyor chain 120 can smoothly pierce the film material.

[0031] It should be noted that after the membrane material is heated and softened, it will undergo some deformation during the conveying process. The subsequent punching module mainly punches the middle part of the membrane material. If the middle part of the membrane material undergoes large deformation, it will affect the quality of the workpiece punched out by the subsequent punching module.

[0032] It is understandable that since the conveyor chain 120 mainly punctures the edge of the film material in the width direction, by setting the limiting seat 220 and placing the heating element 222 inside the limiting seat 220, the heating element 222 can mainly heat and soften the edge of the film material in the width direction, thereby reducing the deformation generated in the middle area of ​​the film material and improving the quality of the workpiece punched out by the subsequent punching module on the film material.

[0033] It should be noted that when the feeding module of this application is working, the film material being fed has various specifications, and the width of the film material varies for different specifications.

[0034] Based on the above problems, in some embodiments of this utility model, reference is made to... Figure 2 and Figure 4 The limiting seat 220 is slidably disposed on the mounting seat 210 along the width direction of the conveyor line 110a; the heating mechanism 200 also includes an adjustment structure 230, which is disposed on the mounting seat 210 and connected to the two limiting seats 220 respectively. The adjustment structure 230 is used to adjust the relative distance between the two limiting seats 220.

[0035] Furthermore, by adjusting the structure 230, the operator can adjust the relative distance between the two limit seats 220, thereby enabling the heating mechanism 200 to heat and soften film materials of different widths, thus improving the versatility of the feeding module of this application.

[0036] In a further embodiment of this utility model, reference is made to... Figure 4The adjusting structure 230 includes a lead screw 231 and a handwheel 232. The lead screw 231 extends along the width direction of the conveyor line 110a and is rotatably mounted on the mounting base 210. The lead screw 231 includes a first connecting section and a second connecting section. The first connecting section is threadedly connected to one of the limiting seats 220, and the second connecting section is threadedly connected to the other limiting seat 220. The direction of the thread on the first connecting section is opposite to the direction of the thread on the second connecting section. The handwheel 232 is connected to one end of the lead screw 231. Under the action of external force, the handwheel 232 can drive the lead screw 231 to rotate.

[0037] Understandably, on the lead screw 231, since the threads on the first connecting section and the second connecting section have opposite directions of rotation, and the first connecting section is threadedly connected to one of the limit seats 220, while the second connecting section is threadedly connected to the other limit seat 220, when the operator rotates the handwheel 232 to drive the lead screw 231 to rotate, the lead screw 231 can simultaneously drive the two limit seats 220 to slide in opposite directions. Thus, the operator can rotate the handwheel 232 to synchronously drive the two limit seats 220 to move closer or further apart, thereby achieving rapid adjustment of the relative distance between the two limit seats 220.

[0038] In some embodiments of this utility model, reference is made to Figure 5 The conveying mechanism 100 also includes a pressure roller 140, which is mounted on the mounting frame 110 and located at the beginning of the conveyor line 110a. The pressure roller 140 is used to press the film material down onto the conveyor chain 120.

[0039] It is understandable that by setting the pressure roller 140, when the membrane material moves to the beginning of the conveyor line 110a, the pressure roller 140 can push the membrane material downwards and closer to the conveyor chain 120, so that the piercing part 121 on the conveyor chain 120 can smoothly pierce the membrane material upwards.

[0040] In a further embodiment of this utility model, the pressure roller 140 is mounted on the mounting frame 110 with adjustable position in the vertical direction.

[0041] Understandably, the adjustable vertical position of the pressure roller 140 allows the operator to adjust its position according to the thickness of the membrane material, thereby enabling the pressure roller 140 to stably press the membrane material downwards, which in turn allows the piercing part 121 on the conveyor chain 120 to successfully pierce the membrane material.

[0042] For details, please refer to Figure 7 The pressure roller 140 is rotatably mounted on the wheel seat 160. The mounting bracket 110 is provided with a vertically extending elongated hole 111. A threaded adjusting member is slidably inserted into the elongated hole 111 and is threadedly connected to the wheel seat 160.

[0043] Then, by loosening the threaded adjustment component, the operator can adjust the position of the wheel seat 160 in the vertical direction to adjust the position of the pressure roller 140 in the vertical direction; by tightening the threaded adjustment component, the wheel seat 160 can be fixed on the mounting bracket 110, thereby fixing the position of the pressure roller 140 in the vertical direction.

[0044] In some embodiments of this utility model, reference is made to Figure 5 Two conveyor chains 120 are wound around the mounting frame 110. The two conveyor chains 120 are distributed at intervals along the width direction of the conveyor line 110a. The piercing parts 121 on the two conveyor chains 120 are respectively used to pierce the two ends of the membrane material in the width direction.

[0045] It is understandable that by setting two conveyor chains 120, the piercing parts 121 on the two conveyor chains 120 can pierce the two ends of the membrane material in the width direction respectively, so that the two conveyor chains 120 can cooperate to drive the membrane material to move along the conveyor line 110a synchronously; the setting of two conveyor chains 120 enables the two ends of the membrane material in the width direction to move synchronously, so as to reduce the probability of the membrane material deviating during the movement.

[0046] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 The drive structure 130 includes a motor 131 and a transmission roller 132. The motor 131 is driven to the transmission roller 132. The two ends of the transmission roller 132 are respectively connected to the two conveyor chains 120 through gears.

[0047] Furthermore, driven by the motor 131, the transmission roller 132 can synchronously drive the two conveyor chains 120 to move.

[0048] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 The mounting frame 110 is provided with a clamping member 112. The clamping member 112 extends along the length of the conveyor line 110a and is located on the upper side of the conveyor chain 120. The clamping member 112 is used to prevent the film material from detaching from the puncture part 121 in the vertical direction.

[0049] It should be noted that although the puncture part 121 on the conveyor chain 120 can puncture the membrane material upwards, there is still a probability that the membrane material will detach upwards from the puncture part 121 during the process of the conveyor chain 120 moving the membrane material.

[0050] It is understood that in the feeding module of this application, by providing a clamping member 112 on the upper side of the conveyor chain 120, the clamping member 112 can limit the film material in the vertical direction, thereby reducing the probability that the film material will detach from the puncture part 121 upwards.

[0051] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 The conveying mechanism 100 also includes a guide roller 150, which is located between the conveying chain 120 and the heating mechanism 200 and is used to guide the film material in the heating mechanism 200 to the beginning of the conveying line 110a.

[0052] Understandably, the guide roller 150 is designed to guide the film material output from the heating mechanism 200 into the conveyor line 110a. On the other hand, the guide roller 150 reduces the probability of the film material rubbing against the edge of the output end of the heating mechanism 200, thereby reducing scratches on the film material.

[0053] The vacuum forming production line provided according to the second aspect of the present invention includes the feeding module provided in the first aspect of the present invention; the vacuum forming production line also includes a punching module, which is used to punch the film material output from the conveyor line 110a.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
