Description

Technical Field

[0001] This invention relates to the field of packaging die-cutting equipment, and more particularly to a die-cutting device and method for rubber-filled candy packaging. Background Technology

[0002] In the industrial production of rubber-filled candies, packaging die-cutting is a crucial step in ensuring the consistency of product appearance and specifications. Existing technologies often face multiple problems in this step: during transport, excessive friction between the packaging and the equipment surface easily leads to wrinkles, misalignment, and even packaging damage; the cutting components are mostly designed with fixed spacing, making it difficult to adapt to different sizes of candy packaging, requiring extensive adjustments to the mechanical structure during changeovers, which is time-consuming and labor-intensive; the levelness of the cutting platform and the conveyor surface is easily affected by equipment vibration, resulting in skewed cuts and dimensional deviations; furthermore, the lack of an effective centering and limiting mechanism makes the packaging prone to tipping over during die-cutting, further exacerbating product quality fluctuations. These problems not only reduce production efficiency and increase scrap rates but also raise equipment maintenance costs, making it difficult to meet the high precision and adaptability requirements of modern production lines. Therefore, we propose a rubber-filled candy packaging die-cutting device and method to solve the aforementioned problems. Summary of the Invention

[0009] Preferably, lifting frames are installed at both the front and rear of the cross frame, and sliding frames are installed on both the front and rear sides of the conveyor belt away from the mounting frame.

[0010] Preferably, a connecting frame is installed between the lifting frames, a pump body is installed in the middle of the connecting frame, the interior of the connecting frame is connected to the interior of the lifting frame, a connecting pipe is installed on one side of the connecting frame, and the side of the connecting pipe away from the connecting frame is fixedly connected to the base, and the base is connected to the interior of the corrugated seat.

[0013] Preferably, a die-cutting method for rubber-filled candy packaging includes the following steps:

[0014] S1. Sandwich candy packaging, conveying, and leveling pretreatment:

[0015] The segmented filled candy packaging is conveyed to the top film by a pre-conveying device; an electric push rod drives the fixed frame and guide wheels to move, so that the guide wheels contact the packaging surface; a hub motor drives the guide wheels to rotate, and the packaging is led out onto the conveyor belt; the conveyor belt stretches the packaging to keep it straight, providing a stable foundation for subsequent processes;

[0016] S2, Top film adjustment and packaging centering limit:

[0017] According to the packaging specifications, the adjustment mechanism is activated through the control panel: the connecting frame pump body inputs liquid into the interior, driving the lifting frame, corrugated seat and bottom cylinder to rise and fall synchronously. When the bottom cylinder moves down, the side plates drive the two rotating plates to flip, forming a "V" shaped guide channel. The bottom cylinder drives the middle of the top film to descend, and together with the rotating plates, it achieves the centering and guiding of the packaging.

[0018] S3, Air cushion formation helps reduce friction:

[0019] Start the air pump, draw air through the output hose into the through pipe and connector, and the gas is sprayed out through the rotating drum slot and the top film air hole to form an "air cushion" between the packaging and the top film to reduce friction. Some of the gas is diverted to the horizontal pipe and blows air to both sides of the packaging through the air outlet to help center it and reduce edge friction.

[0020] S4. Adjustment of the spacing between the split components:

[0021] The inner motor of the rotating frame drives the bidirectional threaded rod to rotate, which in turn drives the threaded block to move closer to or further away. The threaded block drives the support rod to deflect, so that the cutter extends / contracts synchronously, completing the adjustment of the cutting distance to adapt to the current packaging specifications.

[0022] S5. Horizontal calibration of the splitting platform:

[0023] By utilizing the connectivity of the connecting pipes, the lifting frame and the cross frame can be raised and lowered synchronously, ensuring that the cutting platform at the end of the conveyor belt and the top film remain on the same horizontal plane, thus guaranteeing cutting stability.

[0024] S6. Packaging and cutting execution:

[0025] The servo motor drives the rotating frame to rotate, which in turn drives the cutter to rotate synchronously and starts the cutting action. The dual-head motor drives the upright frame to adjust its height according to the unfolded state of the cutter through the rotating shaft, tooth column and tooth groove transmission, ensuring the cutting accuracy.

[0026] S7. Optimize dynamic parameters to achieve continuous assurance:

[0027] The slider is driven by a lead screw to move along the chute, and the distance between the horizontal tube and the packaging is adjusted in real time. The air outlet is continuously attracted by a magnetic strip to ensure that it always faces the center of the top film, thus maintaining the stability of the centering and friction reduction effect.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. In existing technologies, cutting errors are often caused by packaging wrinkles and positional misalignment. This invention uses the synergistic effect of guide wheels and conveyor belts to first accurately guide the packaging onto the conveyor belt, and then use the extension of the conveyor belt to keep the packaging in a straight state, thus solving the wrinkle problem at the source. At the same time, the "V"-shaped guide channel design uses a rotating plate to form a lateral limit on the packaging, effectively preventing tipping and tilting during the conveying process, improving the stability of the conveying, ensuring the foundation for cutting, and providing a stable foundation for subsequent cutting.

[0030] 2. Existing equipment is mostly designed for fixed-specification packaging, and the adjustment for changing models is cumbersome. This invention drives the cutter to extend and retract synchronously through a bidirectional threaded rod, which can quickly adjust the cutting spacing. At the same time, the pump body drives the top film to rise and fall, and the screw adjusts the distance of the horizontal tube, which can flexibly adjust the limit and cutting parameters according to different packaging specifications. There is no need for large-scale replacement of parts, which significantly improves the equipment's adaptability to multi-category production, realizes multi-specification adaptation, and enhances the equipment's flexibility.

[0031] 3. In existing technologies, misalignment during cutting is easily caused by mismatch between the height of the cutting components and the platform, or uneven force. This invention uses a dual-head motor to link the upright frame and the cutter, so that the height of the cutting components can be adjusted in real time according to the unfolded state. At the same time, the connectivity of the connecting pipe ensures that the cutting platform and the top film always remain horizontal, eliminating the cutting error caused by the height difference from a mechanical structure perspective, improving the flatness and dimensional consistency of the cut, optimizing the cutting accuracy, and reducing quality deviation.

[0032] 4. In existing equipment, direct contact between the packaging and the conveyor surface easily generates friction, leading to packaging wear or displacement. This invention innovatively introduces "air cushion" technology: by using an air pump to spray gas between the top film and the packaging to form an isolation layer, combined with auxiliary air blowing from the air outlets on both sides, contact friction is reduced in all directions; at the same time, magnetic strips are used to ensure that the air outlets always face the center, continuously and stably achieving the dual effects of friction reduction and centering, reducing friction damage and effectively protecting the integrity of the packaging appearance.

[0033] 5. In existing technologies, conveying, limiting, and cutting processes often require independent adjustment and have poor coordination. This invention, through the linkage design of mechanical structure and pneumatic-hydraulic drive, enables functions such as conveying and leveling, centering and limiting, cutting adjustment, and friction control to respond synchronously, reducing manual intervention steps; at the same time, the control panel centrally controls various parameters, significantly shortening changeover time and operational complexity, integrating linkage mechanisms, and improving continuous production efficiency.

[0045] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0046] like Figures 1-10The illustrated die-cutting device for rubber-filled candy packaging includes a frame 101. A housing 102 is mounted on one side of the top of the frame 101. A mounting bracket 111 is disposed inside the housing 102. A base 142 is mounted in the middle of the inner side of the mounting bracket 111. A corrugated seat 141 is mounted on the top of the base 142. A bottom cylinder 137 is mounted on the top of the corrugated seat 141. A connector 148 is mounted in the middle of one end of the bottom cylinder 137. A rotating cylinder 149 is rotatably connected to the inner side of the bottom cylinder 137. Multiple sets of evenly distributed slots 151 are formed in the middle of the outer periphery of the rotating cylinder 149. The diameter of each set of slots 151 is different. A fixed shaft 153 is mounted in the middle of one end of each slot 151. The rotating cylinder 149 is located away from the fixed shaft 153. One end of each of the three components is connected to a connector 148. Multiple side plates 138 are connected to both sides of the bottom cylinder 137. A rotating plate 136 is rotatably connected to the side of the side plate 138 away from the bottom cylinder 137. A limiting groove 152 is opened on the inner side of the end of the rotating plate 136 away from the side plate 138. Multiple openings 145 are opened at the bottom edge of the limiting groove 152. A limiting rod 154 is slidably connected inside the limiting groove 152. Multiple connecting blocks 146 are fixedly connected to the outer periphery of the limiting rod 154. The ends of the connecting blocks 146 are all located inside the openings 145. The ends of the connecting blocks 146 away from the limiting rod 154 are fixedly connected to the mounting bracket 111. A magnetic strip 150 is installed in the middle of the rotating plate 136.

[0047] Furthermore, in specific implementation, the connection of the connecting pipe 122 enables the lifting frame 113 and the cross frame 121 to rise and fall synchronously, so that the cutting platform at the end of the conveyor belt 106 can always be kept on the same horizontal plane as the top film 110, thereby ensuring the stability of the cutting operation. During this process, the air pump 143 can draw in the surrounding air and introduce it into the through pipe 115 and the connector 148 through the output hose. The through pipe 115 can further introduce the gas into the rotating drum 149. The gas can be sprayed out through the slot 151 on the rotating drum 149 and further dispersed through the air holes 109 on the top film 110, thereby forming an "air cushion" between the sandwich candy packaging and the top film 110, which can effectively reduce the friction between the packaging and the top film 110, and is conducive to the stable conveying and cutting of the packaging.

[0048] The mounting frame 111 has a conveyor belt 106 on one side, a crossbeam 121 inside the conveyor belt 106, drive rollers on both sides of the crossbeam 121 and the other side of the conveyor belt 106, one of which has a motor installed at its end. Lifting frames 113 are installed at the front and rear of the crossbeam 121. Slides 123 are installed on the front and rear sides of the conveyor belt 106 away from the mounting frame 111. A fixed seat 126 is provided on one side of the slide 123, and multiple guide rods 125 are fixedly connected to the end of the fixed seat 126. The ends of the guide rods 125 are slidably connected to the slides 123, and top springs 124 are sleeved on the outer periphery of each guide rod 125. Connecting frames 127 are installed between the lifting frames 113. A pump body is installed in the middle of the connecting frame 127. The interior of the connecting frame 127 is connected to the interior of the lifting frame 113. A connecting pipe 122 is installed on one side of the connecting frame 127. The side of the connecting pipe 122 away from the connecting frame 127 is fixedly connected to the base 142. The base 142 is connected to the interior of the corrugated seat 141. A top membrane 110 is provided on the top of the bottom cylinder 137. The top membrane 110 has evenly distributed air holes 109 in the middle. The bottom middle of the top membrane 110 is connected to the bottom cylinder 137. Both ends of the top membrane 110 are wound with take-up rollers 147. The take-up rollers 147 are installed on both sides of the mounting frame 111. The ends of the take-up rollers 147 are connected to the wall of the mounting frame 111 through coil springs.

[0049] Furthermore, in specific implementation, during the cutting process, the top film 110 can be adjusted via control panel 104 according to the specific specifications of the filled candy packaging. A liquid storage tank is installed between the connecting frames 127. The pump draws liquid from the storage tank and delivers hydraulic medium to the connecting frame 127. The base 142 and corrugated seat 141 are connected via connecting pipe 122, thus forming a linkage mechanism between the lifting frame 113 and the corrugated seat 141. At this time, the lifting frame 113 and the corrugated seat 141 act as a "hydraulic rod," and the flow valve on the connecting pipe 122 and the connecting frame 127 is activated by the pump. The amount of liquid input can be controlled, thereby enabling control and synchronization of the lifting height of the lifting frame 113 and the corrugated seat 141. The corrugated seat 141 can drive the bottom cylinder 137 to move synchronously. The corrugated seat 141 will drive the bottom cylinder 137 to rise and fall. When the bottom cylinder 137 moves down, the side plate 138 will drive the rotating plates 136 on both sides to flip. The bottom cylinder 137 can drive the middle of the top film 110 to descend synchronously. The rotating plate 136 can form a "V" shaped guide channel, thereby enabling the centering and guiding of the sandwich candy packaging, which is beneficial for practical use.

[0050] The mounting bracket 111 has sliding grooves 134 on both sides of its top. Slider 135 is slidably connected to the inner side of each sliding groove 134. A lead screw 144 passes through the middle of each slider 135 on one side. The lead screw 144 is installed on one side of the top of the mounting bracket 111. The threaded part of the lead screw 144 is threadedly connected to the slider 135. A horizontal tube 140 is installed between the two sliders 135 on both sides. An air outlet 139 is installed on one side of each horizontal tube 140. A through pipe 115 is fixedly connected to one end of each horizontal tube 140. The end of the air outlet 139 is made of ferromagnetic material.

[0051] Furthermore, in specific implementation, some gas is introduced into the horizontal tube 140 through the through-pipe 115 and discharged through the air outlet 139, thereby supplementing air to both sides of the packaging, reducing friction between the sandwich candy packaging and the top film 110 from all directions. At the same time, the gas through the air outlets 139 on both sides can center the sandwich candy packaging, maintain its stability, and prevent it from tipping over. Meanwhile, the lead screws 144 on both sides drive the slider 135 to move along the slide groove 134, thereby adjusting the distance between the horizontal tube 140 and the sandwich candy packaging. Furthermore, during the adjustment of the rotating plate 136 and the horizontal tube 140, the magnetic strip 150 can continuously attract the air outlet 139, so that the outlet of the air outlet 139 is continuously facing the center of the top film 110, thus keeping the above working process stable and beneficial to practical use.

[0052] An electric push rod 108 is installed on one side of the top inside the housing 102. A fixed frame 112 is installed at the bottom telescopic end of the electric push rod 108. A guide wheel 105 is installed on the inner side of the fixed frame 112 via a hub motor. A side frame 103 is installed on the rear side of one side of the frame 101. A control panel 104 is installed on the front side of the side frame 103. An air pump 143 is installed on one side of the base 142. The output of the air pump 143 is connected to a connector 148 and a connecting pipe 115.

[0053] Furthermore, in specific implementation, the equipment can cut the filled candy packaging. After the packaged and segmented filled candy is conveyed to the top film 110 by the pre-conveying equipment, the electric push rod 108 can drive the fixed frame 112 and the guide wheel 105 to move, so that the guide wheel 105 can contact the filled candy packaging on the top film 110. The hub motor on the fixed frame 112 can drive the guide wheel 105 to rotate, and the guide wheel 105 can drive the filled candy packaging at the bottom to move. The guide wheel 105 can guide the filled candy packaging onto the conveyor belt 106. The operation of the conveyor belt 106 can cause the filled candy packaging to stretch, so that the filled candy packaging can be kept in a straight state, which is convenient for subsequent cutting work.

[0054] The frame 121 has a rotating frame 128 on its upper side. The rotating frame 128 has multiple guide grooves 129 on its outer periphery. A bidirectional threaded rod 133 is rotatably connected to the inner side of the rotating frame 128. Threaded blocks 130 are threadedly connected to both sides of the outer periphery of the bidirectional threaded rod 133. Evenly distributed support rods 131 are rotatably connected to the outer periphery of the threaded blocks 130. A cutter 107 is rotatably connected to the end of each support rod 131 away from the threaded blocks 130. The support rods 131 are all located inside the guide grooves 129. A stepper motor is installed at the end of the bidirectional threaded rod 133. The stepper motor is installed on one end of the rotating frame 128. The threaded blocks 130 are slidably connected to the inner side of the rotating frame 128. Sliding sleeves 132 are fixedly connected to both sides of the end of the cutter 107 near the rotating frame 128. The ends of the sliding sleeves 132 away from the cutter 107 are fixedly connected to the rotating frame 128.

[0055] Furthermore, in specific implementation, the motor installed inside the rotating frame 128 can drive the bidirectional threaded rod 133 to rotate. The bidirectional thread on the bidirectional threaded rod 133 can drive the threaded block 130 to move closer or further away. When the threaded block 130 moves, it will drive the support rod 131 to deflect. The support rod 131 will drive each cutter 107 to extend and retract. The extension and retraction of the cutter 107 can realize the synchronous adjustment of the distance between each cutter 107, which is beneficial to practical use. During cutting, the servo motor 116 can drive the rotating frame 128 to rotate, thereby driving the cutter 107 to rotate synchronously and complete the cutting work.

[0056] The conveyor belt 106 is equipped with uprights 114 on both the front and rear sides. The uprights 114 are slidably connected to the top of the frame 101. The lower middle part of the uprights 114 is provided with toothed grooves 118. The bottom of the frame 101 is fixedly connected to a double-headed motor 119. The drive ends of the double-headed motor 119 are fixedly connected to rotating shafts 120. The ends of the rotating shafts 120 are fixedly connected to toothed columns 117. The toothed columns 117 are meshed with the toothed grooves 118. A servo motor 116 is installed at one end of the rotating frame 128. The servo motor 116 is installed on the upper part of one of the uprights 114.

[0057] Furthermore, in specific implementation, the dual-head motor 119 can drive the rotating shafts 120 at both ends to rotate. The rotating shafts 120 will drive the toothed column 117 to rotate synchronously. The toothed column 117 will drive the upright frame 114 to move up and down through the toothed grooves 118 that mesh with it. The upright frame 114 can adjust its height according to the unfolded state of the cutter 107, so that the cutter 107 can complete the cutting work of the filled candy packaging.

[0058] One method for die-cutting packaging for rubber-filled candies includes the following steps:

[0059] S1. Sandwich candy packaging, conveying, and leveling pretreatment:

[0060] The segmented sandwich candy packaging is conveyed to the top film 110 by the pre-conveying equipment. The electric push rod 108 drives the fixed frame 112 and guide wheel 105 to move, so that the guide wheel contacts the packaging surface. The hub motor drives the guide wheel 105 to rotate, and the packaging is exported to the conveyor belt 106. The conveyor belt 106 stretches the packaging to keep it straight, providing a stable foundation for subsequent processes.

[0061] S2, Top film adjustment and packaging centering limit:

[0062] According to the packaging specifications, the adjustment mechanism is activated through the control panel 104: the pump body of the connecting frame 127 inputs liquid into the interior, driving the lifting frame 113, the corrugated seat 141 and the bottom cylinder 137 to rise and fall synchronously. When the bottom cylinder 137 moves down, it drives the two side rotating plates 136 to flip through the side plate 138 to form a "V" shaped guide channel. The bottom cylinder 137 drives the middle of the top film 110 to fall, which, together with the rotating plate 136, realizes the centering and guiding of the packaging.

[0063] S3, Air cushion formation helps reduce friction:

[0064] Start the air pump 143 to draw air through the output hose into the through pipe 115 and connector 148. The gas is sprayed out through the slot 151 of the rotating drum 149 and the air hole 109 of the top film 110, forming an "air cushion" between the packaging and the top film to reduce friction. Some of the gas is diverted to the horizontal pipe 140 and blows air to both sides of the packaging through the air outlet 139 to help center it and reduce edge friction.

[0065] S4. Adjustment of the spacing between the split components:

[0066] The inner motor of the rotating frame 128 drives the bidirectional threaded rod 133 to rotate, which in turn drives the threaded block 130 to move closer to / away from the bidirectional thread. The threaded block 130 drives the support rod 131 to deflect, so that the cutter 107 extends / retracts synchronously, thus completing the adjustment of the cutting distance to adapt to the current packaging specifications.

[0067] S5. Horizontal calibration of the splitting platform:

[0068] By utilizing the connectivity of the connecting pipe 122, the lifting frame 113 and the cross frame 121 are raised and lowered synchronously, ensuring that the cutting platform at the end of the conveyor belt 106 and the top film 110 remain on the same horizontal plane, thus ensuring cutting stability.

[0069] S6. Packaging and cutting execution:

[0070] Servo motor 116 drives the rotating frame 128 to rotate, which drives the cutter 107 to rotate synchronously and start the cutting action. Dual-head motor 119 drives the upright frame 114 to adjust its height as the cutter 107 unfolds, through the rotating shaft 120, tooth column 117 and tooth groove 118, to ensure cutting accuracy.

[0071] S7. Optimize dynamic parameters to achieve continuous assurance:

[0072] The slider 135 is driven by the lead screw 144 to move along the slide groove 134, and the distance between the horizontal tube 140 and the packaging is adjusted in real time. The magnetic strip 150 continuously attracts the air outlet 139 to ensure that it always faces the center of the top film 110, thus maintaining the stability of the centering and friction reduction effect.

[0073] Working principle:

[0074] In practical use, the equipment can cut the filled candy packaging. After being divided into compartments, the filled candy is conveyed to the top film 110 by the pre-conveyor. The electric push rod 108 drives the fixed frame 112 and guide wheel 105 to move, allowing the guide wheel 105 to contact the filled candy packaging on the top film 110. The hub motor on the fixed frame 112 drives the guide wheel 105 to rotate, which in turn moves the bottom-contacted filled candy packaging. The guide wheel 105 guides the filled candy packaging onto the conveyor belt 106. The operation of the conveyor belt 106 stretches the filled candy packaging, keeping it straight for subsequent cutting. The rotating frame 128... The motor installed on the inner side can drive the bidirectional threaded rod 133 to rotate. The bidirectional thread on the bidirectional threaded rod 133 can drive the threaded block 130 to move closer or further away. When the threaded block 130 moves, it will drive the support rod 131 to deflect. The support rod 131 will drive each cutter 107 to extend and retract. The extension and retraction of the cutter 107 can realize the synchronous adjustment of the distance between each cutter 107, which is beneficial to practical use. During the cutting, the servo motor 116 can drive the rotating frame 128 to rotate, thereby driving the cutter 107 to rotate synchronously and complete the cutting work. During this process, the dual-head motor 119 can drive the rotating shafts 120 at both ends to rotate. The rotating shafts 120 will drive the toothed column 11 7 rotates synchronously. The toothed column 117, through its meshing toothed groove 118, drives the upright frame 114 to move up and down. The upright frame 114 can adjust its height according to the unfolded state of the cutter 107, allowing the cutter 107 to complete the cutting of the filled candy packaging. During the cutting process, the top film 110 can be adjusted via the control panel 104 according to the specific specifications of the filled candy packaging. The operation of the pump on the connecting frame 127 allows liquid to be input into the connecting frame 127 and the connecting pipe 122, thereby driving the lifting frame 113 and the corrugated seat 141 to move up and down synchronously. Specifically, the pump draws liquid from the storage tank, delivers hydraulic medium to the connecting frame 127, and connects to the base 1 through the connecting pipe 122. 42 and the corrugated seat 141 form a linkage mechanism between the lifting frame 113 and the corrugated seat 141. At this time, the lifting frame 113 and the corrugated seat 141 act as a "hydraulic rod." The amount of liquid input into them can be controlled by the flow valves on the pump body, connecting pipe 122, and connecting frame 127, thereby enabling control and synchronization of the lifting height of the lifting frame 113 and the corrugated seat 141. The corrugated seat 141 drives the bottom cylinder 137 to move synchronously, and the bottom cylinder 137 is raised and lowered. When the bottom cylinder 137 moves downward, the side plates 138 drive the rotating plates 136 on both sides to flip. The bottom cylinder 137 drives the middle of the top membrane 110 to descend synchronously, and the rotating plates 136 form a "V"-shaped guide channel.This allows for centered side positioning and guidance of the filled candy packaging, which is beneficial for practical use. During this process, the connecting pipe 122 enables the lifting frame 113 and the cross frame 121 to rise and fall synchronously, ensuring that the cutting platform at the end of the conveyor belt 106 remains on the same horizontal plane as the top film 110, thus maintaining stable cutting operations. During this process, the air pump 143 draws in ambient air and introduces it into the through pipe 115 and connector 148 through the output hose. The through pipe 115 further introduces the gas into the rotating drum 149, where it is ejected through the slot 151 and further dispersed through the air holes 109 on the top film 110. This creates an "air cushion" between the filled candy packaging and the top film 110, effectively reducing friction between the packaging and the top film 110 and contributing to packaging stability. During the fixed-conveying and cutting process, some gas is introduced into the horizontal tube 140 through the through-pipe 115 and discharged through the air outlet 139. This allows for air replenishment on both sides of the packaging, comprehensively reducing friction between the filled candy packaging and the top film 110. Simultaneously, the gas through the air outlets 139 centers the filled candy packaging, maintaining its stability and preventing it from tipping over. Meanwhile, the lead screws 144 on both sides drive the slider 135 to move along the slide groove 134, thereby adjusting the distance between the horizontal tube 140 and the filled candy packaging. Furthermore, during the adjustment of the rotating plate 136 and the horizontal tube 140, the magnetic strip 150 continuously attracts the air outlet 139, ensuring that the outlet of the air outlet 139 continuously faces the center of the top film 110. This stabilizes the entire process and is beneficial for practical use.
