Description

Technical Field

[0001] The present application relates to the technical field of manufacturing, and in particular, to a film loading mechanism and a processing device. Background Art

[0002] Mylar film is a highly transparent, heat-resistant, and chemically corrosion-resistant polyester film, with excellent physical properties and chemical stability. It has a wide range of applications in multiple fields, such as electronics, food, medicine, and construction. In some scenarios of automatic loading, for example, in plastic processing plants, electronic product manufacturing plants, food packaging production lines, etc., or in some experimental scenarios applied to scientific research institutions, there are high requirements for the quality, size, and position of Mylar film. In order to supply Mylar film quickly, accurately, and continuously, an Mylar film loading mechanism is usually used for processing. This mechanism can automatically complete the loading process of Mylar film, improving production efficiency and reducing the cumbersome and error-prone manual operations.

[0003] The existing Mylar film loading mechanism is usually composed of an absorbing mechanism and a placing mechanism for Mylar film. However, when using the above-mentioned mechanism to absorb and transfer Mylar film, the following problems exist: 1. Due to the fixation of the film material and the fluctuation of the vacuum air source, the Mylar film cannot be sucked up flatly, resulting in possible deformation when it reaches the loading position and cannot be used continuously; 2. Components such as the vacuum air source and translation cylinder in the mechanism will also affect the corresponding static elimination effect, leading to the disadvantage of sucking multiple Mylar films simultaneously; 3. The current Mylar film loading mechanism has a long loading stroke and the suction plate sucks the Mylar film slowly. Therefore, the current Mylar film loading mechanism has a poor loading effect and a low loading efficiency, and cannot meet the increasing production capacity requirements. Summary of the Utility Model

[0004] In view of this, the purpose of the embodiments of the present application is to provide a film loading mechanism and a processing device to improve the problems of poor loading effect and low loading efficiency of the film loading mechanism in the existing technology.

[0005] To solve the above problems, in the first aspect, the embodiments of the present application provide a film loading mechanism, which includes: a placement table, a pressure member, and a discharging assembly;

[0006] The placement table is set as a table structure including a slope section; the bottom of the slope section is connected to the discharging assembly;

[0007] The placement table is used for placing film materials;

[0008] The pressure member is used to fix the absolute position of the film material placed on the placement table;

[0009] The discharging assembly is used to move the target film material in the film material that contacts the placing table to the discharging position.

[0010] In the above implementation process, the film material is placed by setting a placing table with a ramp section, so that the film material freely hangs under the influence of gravity, and a pressing member is used to apply pressure to the film material to fix the film material in combination with the placing table. The discharging assembly moves the target film material in multiple film materials that contact the placing table to the corresponding discharging position to achieve automatic feeding. There is no need to set an adsorption mechanism in the film feeding mechanism to adsorb the film material, thereby eliminating the influence of air source fluctuations on the flatness of the film material, effectively reducing the deformation of the film material during the adsorption process and the adverse situation of multiple film materials being adsorbed simultaneously. Moreover, the structure of the film feeding mechanism is simple, the cost is low, and the feeding stroke of the film material is short, thereby improving the feeding efficiency of the film feeding mechanism, optimizing the feeding effect, and being able to meet various current production requirements.

[0011] Optionally, the bottom of the placing table is arranged parallel to the first direction; wherein, the first direction is the discharging direction of the film material;

[0012] The pressing member is arranged at the first position; wherein, the first position is arranged at the top of the ramp section at the first end of the placing table close to the discharging assembly in the second direction, and the second direction is a direction perpendicular to the first direction.

[0013] In the above implementation process, the bottom of the placing table is placed parallel to the first direction of the film material discharging, and the first end of the placing table close to the discharging assembly is a ramp section to facilitate the discharging of the film material under the influence of gravity. Moreover, in order to press the film material on the placing table, in the second direction perpendicular to the first direction, the pressing member can be arranged at the first position at the top of the ramp section of the placing table to apply pressure to the film material and fix the film material on the ramp section, so that the discharging assembly can drive the target film material at the bottom to move while the other film materials are not affected, effectively optimizing the discharging effect of the film material.

[0014] Optionally, the film feeding mechanism further includes: a fixing member;

[0015] The fixing member is arranged at the second position; wherein, the second position is arranged at the top of the second end of the placing table far from the discharging assembly in the second direction;

[0016] The fixing member is used to fix the first end of the film material so that the film material hangs on the placing table.

[0017] In the above implementation process, in order to fixedly place the film material, a corresponding fixing member may also be provided at a second position on the top of the second end of the placing table away from the discharging assembly to fix the first end of the film material, so that the film material can be suspended on the placing table. Affected by gravity, the gap between the film materials becomes larger, facilitating discharging.

[0018] Optionally, the film loading mechanism further includes: an electrostatic eliminating assembly;

[0019] The electrostatic eliminating assembly is arranged at a third position; wherein, the distance between the third position and the second position is less than or equal to a preset distance;

[0020] The electrostatic eliminating assembly is used to provide electrostatic eliminating wind for the film material;

[0021] In the plane formed by the second direction and the first direction, the setting direction of the air outlet channel of the electrostatic eliminating assembly is parallel to the placing direction of the film material.

[0022] In the above implementation process, due to the material characteristics of the film material, there may be an electrostatic situation. Therefore, a corresponding electrostatic eliminating assembly can be arranged at a third position near the second position. Since the film materials are affected by gravity and the gap between them becomes larger, the electrostatic eliminating assembly can be used to provide electrostatic eliminating wind for the film material to effectively eliminate the static electricity between the film materials, thereby reducing adverse situations such as film material adhesion caused by static electricity. Moreover, in order to further improve the effectiveness of the electrostatic eliminating wind, in the plane formed by the second direction and the first direction, the setting direction of the air outlet channel of the electrostatic eliminating assembly can be parallel to the placing direction of the film material, so that the wind direction of the electrostatic eliminating wind is parallel to the placing direction of the film material, thereby optimizing the electrostatic eliminating effect of the electrostatic eliminating assembly.

[0023] Optionally, the electrostatic eliminating assembly includes an ion wind bar.

[0024] In the above implementation process, the electrostatic eliminating assembly can include various types of functional devices such as ion wind bars that can provide electrostatic eliminating wind.

[0025] Optionally, the discharging assembly includes: a motor and a rotating member;

[0026] The motor is connected to the rotating member; the rotating member is in contact with the target film material;

[0027] The motor is used to provide power for the rotating member;

[0028] The rotating member is used to rotate based on the power to drive the target film material to move to the discharging position through rotation.

[0029] In the above implementation process, in order to drive the target film material at the bottom layer in contact with the placement table among multiple film materials to move, the discharging component may include a motor and a rotating member. The rotating member is connected to the bottom of the ramp section of the placement table near the discharging position, and the motor is used to drive the rotating member to rotate, so as to drive the contacted target film material to move through the rotation of the rotating member, thereby moving the target film material to the corresponding discharging position. Driving the film material to move by rotation can reduce the situation of sending out multiple film materials at the same time, effectively reduce the cost and complexity of the discharging component, thereby reducing the cost of the film loading mechanism, reducing the length of the loading stroke, and improving the loading efficiency.

[0030] Optionally, the first friction coefficient between the surface of the rotating member and the target film material is greater than the second friction coefficient between the target film material and other film materials.

[0031] In the above implementation process, since the target film material is driven to move by friction when the rotating member rotates, therefore, in order to improve the effectiveness of the frictional movement, the surface of the rotating member can be set to a material with relatively large frictional force, so that the first friction coefficient between the surface of the rotating member and the target film material can be greater than the second friction coefficient between the target film material and other film materials, so that the frictional force between the rotating member and the target film material can be greater than the sliding resistance between the film materials, thereby enabling the rotating member to drive the target film material to move normally.

[0032] Optionally, the film loading mechanism further includes: a positioning member;

[0033] The positioning member is arranged at the first edge of the discharging position away from the placement table;

[0034] The positioning member is set as at least one protruding member, and the protruding member is used to limit the movement of the target film material moving to the discharging position in the direction pointing to the first edge based on the protruding structure.

[0035] In the above implementation process, considering that after the film material is discharged, due to the influence of inertia, the film material may continue to move, resulting in the unfavorable situation of inaccurate film material position during loading. Therefore, a corresponding positioning member can also be arranged at the first edge of the discharging position away from the placement table. The positioning member can be one or more protruding members, so as to limit the target film material moving to the discharging position from continuing to move in the direction of the first edge according to its protruding structure. The position of the film material after discharging can be constrained by the positioning member, effectively improving the problem of inaccurate film material position.

[0036] Optionally, the pressing member includes: a pressing plate and a spring assembly;

[0037] Wherein, the contact surface of the pressing plate in contact with the film material is set to conform to the shape of the ramp section;

[0038] The spring assembly is used to expand and contract according to the quantity of the film material to apply a constant pressure to the pressing plate.

[0039] The pressing plate is used to press the film material against the ramp section based on the constant pressure to fix the absolute position between the film material and the placement table.

[0040] In the above implementation process, the pressure member can be composed of a spring assembly and a pressing plate to produce corresponding changes according to the changes of the film material. To adapt to the placement of the film material on the ramp section of the placement table, the contact surface between the pressing plate and the base of the film material can be set to conform to the shape of the ramp section, so as to generate pressure to fix the film material in conformity with the ramp section, improving the effectiveness of the downward pressure. And, since there are quantity changes in the film material during the discharging process, in order to apply sufficient pressure to the film material during the overall discharging process, the spring assembly can expand and contract according to the quantity of the film material to apply a constant pressure to the pressing plate, so that the pressing plate presses the film material against the ramp section based on the constant pressure, providing sufficient downward pressure for the film material to fix the absolute position between the film material and the placement table, effectively ensuring the stability of the discharging process.

[0041] In a second aspect, the embodiment of the present application further provides a processing device, and the processing device includes the film loading mechanism described in any one of the above.

[0042] In summary, the embodiment of the present application provides a film loading mechanism and a processing device. The film material is fixed by the combination of the pressure member and the placement table, and the target film material in contact with the placement table among multiple film materials is moved to the corresponding discharging position through the discharging assembly to achieve automatic loading. There is no need to set an adsorption mechanism to process the film material, effectively reducing the deformation of the film material and the adverse situation of multiple film materials being adsorbed simultaneously. Moreover, the loading stroke of the film material is short, improving the loading efficiency of the film loading mechanism and optimizing the loading effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the embodiments of the present application.

[0048] Mylar film is a highly transparent, heat-resistant, and chemically corrosion-resistant polyester film with excellent physical properties and chemical stability. It has a wide range of applications in multiple fields, such as electronics, food, medicine, and construction. In the electronics field, Mylar film can be used as the dielectric of capacitors, with high insulation strength and low loss characteristics, and is widely used in electronic products. At the same time, it can also be used as the material for glitter, used to make high-precision patterns and characters, especially widely used in fields such as LED displays. In addition, Mylar film can be used as an electrical insulation material and can be used as the surface protection layer of solar panels to prevent damage caused by the external environment. In the food and medicine fields, the application of Mylar film is also very extensive. It can be made into food preservative film, with good moisture-proof and airtight properties, which can effectively extend the shelf life of food. At the same time, it can also be made into food containers, such as boxes, trays, etc., with good transparency and heat resistance. In the medicine field, Mylar film can maintain the humidity and freshness of medicines and is a common medicine packaging material.

[0049] In some scenarios of automated feeding, for example, in fields such as plastic processing plants, electronic product manufacturing plants, food packaging production lines, or some experimental scenarios applied to scientific research institutions, there are high requirements for the quality, size, and position of Mylar film. In order to supply Mylar film quickly, accurately, and continuously, a Mylar film feeding mechanism is usually used for processing. This mechanism can automatically complete the feeding process of Mylar film, improving production efficiency and reducing the cumbersome and error-prone manual operations.

[0050] The existing Mylar film loading mechanism is usually composed of a Mylar film suction mechanism and a placement mechanism. However, during the research process, the applicant found that when using the above-mentioned current mechanism to suck and transfer the Mylar film, the following problems exist: 1. Due to the fixation of the film material and the fluctuation of the vacuum air source, the Mylar film cannot be sucked up flatly, resulting in possible deformation when it reaches the loading position and being unable to be used continuously; 2. Components such as the vacuum air source and translation cylinder in the mechanism will also affect the corresponding static elimination effect, leading to the unfavorable situation of sucking multiple Mylar films simultaneously; 3. The current Mylar film loading mechanism has a long loading stroke and the suction plate sucks the Mylar film slowly. Therefore, the current Mylar film loading mechanism has a poor loading effect and a low loading efficiency, and cannot meet the increasing production capacity requirements.

[0051] To solve the above problems, the present application provides a film loading mechanism that does not require setting an adsorption mechanism to adsorb the film material, thereby eliminating the influence of air source fluctuation on the flatness of the film material, effectively improving the loading efficiency of the film material, and optimizing the loading effect of the film material. The film loading mechanism provided by the embodiments of the present application can be set in various types of processing equipment, such as battery manufacturing equipment, food packaging equipment, pharmaceutical packaging equipment, etc.

[0052] Please refer to Figure 1 , Figure 1 which is a schematic side view structure of a film loading mechanism provided by an embodiment of the present application. Among them, the film loading mechanism may include: a placement table 110, a pressure member 120, and a discharging assembly 130.

[0053] It should be noted that the placement table 110 is set as a table structure including a slope section, the bottom of the slope section is connected to the discharging assembly 130, the placement table 110 is used to place the film material, the pressure member 120 is used to fix the absolute position of the film material placed on the placement table 110, and the discharging assembly 130 is used to move the target film material in the film material that contacts the placement table 110 to the discharging position D.

[0054] Optionally, the film material can be a Mylar film or other types of thin films, which can be set according to the actual application scenarios and requirements. The set film material can include multiple layers of thin films, and the number of film materials can also be set according to the loading requirements and the actual situation of the mechanism. For example, 200 layers of thin films are placed for loading each time, etc. The target film material is the film material in the multiple layers of film materials that directly contacts the placement table 110, that is, the bottom layer film material closest to the placement table 110 in the multiple layers of film materials.

[0055] Optionally, the placement table 110 can be set as a table structure with one end being a slope section and the other end being a platform, or can also be set as a table structure with the whole being a slope section. The pressure member 120 can be set as a pressure plate or multiple point pressure structures, and the discharging assembly 130 can be set as a conveying structure with a moving function, etc.

[0056] Among them, the film material is placed by setting the placing table 110 with a ramp section, so that the film material freely hangs down under the influence of gravity, and the pressure member 120 applies pressure to the film material to fix the film material in combination with the placing table 110. The discharging assembly 130 moves the target film material in contact with the placing table 110 among multiple film materials to the corresponding discharging position D to achieve automatic feeding.

[0057] In Figure 1 In the illustrated embodiment, there is no need to provide an adsorption mechanism in the film feeding mechanism provided by the present application to adsorb the film material, thereby eliminating the influence of air source fluctuations on the flatness of the film material, effectively reducing the deformation of the film material during the adsorption process and the adverse situation of multiple film materials being adsorbed simultaneously. Moreover, the structure of the film feeding mechanism is simple, the cost is low, and the feeding stroke of the film material is short, thereby improving the feeding efficiency of the film feeding mechanism, optimizing the feeding effect, and being able to meet various different production requirements at present.

[0058] It should be noted that please refer to Figure 2 , Figure 2 which is a schematic side structure diagram of another film feeding mechanism provided by an embodiment of the present application. In order to reduce the adverse effects of external factors such as dust and water vapor on the film material during the discharging process, the placing table 110 in the film feeding mechanism can be arranged in the corresponding outer shell 140, and the pressure member 120 can be fixed on the outer shell 140 to provide stable pressure for the film material. A switchable door structure can be arranged on the outer shell 140. For example, it is opened and closed through the rotating shaft 141 to supplement the film material and provide a relatively closed cavity when closed to reduce the external influence. Moreover, a corresponding discharging port can be arranged on the outer shell 140, and the bottom of the ramp section of the placing table 110 and the discharging assembly 130 can be connected at the position of the discharging port to achieve normal discharging while protecting the film material.

[0059] Optionally, in order to improve the stability of the discharging process, the film feeding mechanism can also be arranged on the corresponding support platform to provide a stable and smooth feeding environment for the film feeding mechanism.

[0060] Optionally, the bottom of the placement table 110 is arranged parallel to the first direction A, where the first direction A is the discharging direction of the film material. The pressing member 120 is arranged at the first position, where the first position is arranged at the top of the ramp section of the first end of the placement table 110 close to the discharging assembly 130 in the second direction B, and the second direction B is a direction perpendicular to the first direction A. The bottom of the placement table 110 is placed parallel to the first direction A of the film material discharging, and the first end of the placement table 110 close to the discharging assembly 130 is a ramp section to facilitate the discharging of the film material under the influence of gravity. Moreover, in order to press the film material onto the placement table 110, in the second direction B perpendicular to the first direction A, the pressing member 120 can be arranged at the first position at the top of the ramp section of the placement table 110 to apply pressure to the film material and fix the film material on the ramp section, so that the underlying target film material can be driven to move by the discharging assembly 130 while other film materials are not affected, effectively optimizing the discharging effect of the film material.

[0061] Exemplarily, the first position can be arranged in the second direction B, at the position of the housing 140 corresponding to directly above the set position on the ramp section. The pressing member 120 can be fixed at the first position on the housing 140 by means such as screws and buckles. The set position can be determined according to the specific conditions of the ramp section and the film material. For example, the middle position of the ramp section can be selected as the set position, etc.

[0062] Optionally, in order to fixedly place the film material, the film loading mechanism can further include: a fixing member 150, and the fixing member 150 is arranged at the second position, where the second position is arranged at the top of the second end of the placement table 110 far from the discharging assembly 130 in the second direction B. The fixing member 150 is used to fix the first end of the film material so that the film material hangs over the placement table 110. A corresponding fixing member 150 can be arranged at the second position at the top of the second end of the placement table 110 far from the discharging assembly 130 to fix the first end of the film material far from the discharging position D, so that the film material can be hung over the placement table 110. Compared with the flat placement method, the hanging placement method makes the film material affected by gravity and the gap between the film materials become larger, thus facilitating discharging.

[0063] Exemplarily, in the case where the placement table 110 further includes a platform structure, the second position can be arranged in the second direction B, at the position of the housing 140 corresponding to directly above the center point of the platform at the second end of the placement table 110 and other positions. The fixing member 150 can be a component with a fixing function such as a clamping jaw. The fixing member 150 can be fixed at the second position on the housing 140 by means such as screws and buckles.

[0064] Optionally, due to the material properties of the film material, for example, when plastic films come into contact with each other, there may be a certain electrostatic situation. Therefore, the film loading mechanism may further include: an electrostatic elimination component 160. The electrostatic elimination component 160 is disposed at a third position, where the distance between the third position and the second position is less than or equal to a preset distance. The electrostatic elimination component 160 is used to provide electrostatic elimination air for the film material. On the plane formed by the second direction B and the first direction A, the setting direction of the air outlet channel 161 of the electrostatic elimination component 160 is parallel to the placement direction of the film material. The corresponding electrostatic elimination component 160 can be disposed at the third position near the second position. Due to the influence of gravity on the film material, the gap between the film materials becomes larger. Therefore, the electrostatic elimination component 160 can be used to provide electrostatic elimination air for the film material to effectively eliminate the static electricity between the film materials, thereby reducing adverse situations such as film material adhesion caused by static electricity. Moreover, in order to further improve the effectiveness of the electrostatic elimination air, on the plane formed by the second direction B and the first direction A, the setting direction of the air outlet channel 161 of the electrostatic elimination component 160 can be parallel to the placement direction of the film material, so that the wind direction of the electrostatic elimination air is parallel to the placement direction of the film material, thereby optimizing the electrostatic elimination effect of the electrostatic elimination component 160.

[0065] Exemplarily, the preset distance can be determined according to the actual size parameters of the film loading mechanism. For example, the preset distance is set to 5 cm, so that the electrostatic elimination component 160 can be installed near the fixing member 150 to increase the effective range of the electrostatic elimination air, thereby optimizing the electrostatic elimination effect of the electrostatic elimination component 160.

[0066] Exemplarily, the electrostatic elimination component 160 can include various types of functional devices such as ion blowers that can provide electrostatic elimination air.

[0067] Optionally, in order to drive the target film material at the bottom layer in contact with the placement table 110 among multiple film materials to move, the discharging component 130 may include: a motor 131 and a rotating member 132. The motor 131 and the rotating member 132 are connected, and the rotating member 132 is in contact with the target film material. The motor 131 is used to provide power for the rotating member 132, and the rotating member 132 is used to rotate based on the power to drive the target film material to move to the discharging position D through rotation. The rotating member 132 is connected to the bottom of the slope section of the placement table 110 near the discharging position D, and the motor 131 provides power for the rotating member 132 in the direction pointing to the discharging position D. By driving the rotating member 132 to rotate through the motor 131, the target film material in contact is driven to move through the rotation of the rotating member 132, so as to move the target film material to the corresponding discharging position D. Driving the film material to move by rotation can reduce the situation of sending out multiple film materials at the same time, effectively reduce the cost and complexity of the discharging component 130, thereby reducing the cost of the film loading mechanism, reducing the length of the loading stroke, and improving the loading efficiency.

[0068] It should be noted that the first friction coefficient between the surface of the rotating member 132 and the target film is greater than the second friction coefficient between the target film and other films. Since the rotating member 132 drives the target film to move through friction when rotating, therefore, in order to improve the effectiveness of the frictional movement, the surface of the rotating member 132 can be set to a material with a relatively large frictional force, so that the first friction coefficient between the surface of the rotating member 132 and the target film can be greater than the second friction coefficient between the target film and other films, so that the frictional force between the rotating member 132 and the target film can be greater than the sliding resistance between the films, so that the rotating member 132 can drive the target film to move normally.

[0069] Exemplarily, the rotating member 132 can be set to a structure such as a roller, and the surface of the roller can be coated with a rubber structure to increase the frictional force between the rotating member 132 and the target film and reduce the relative sliding between the films.

[0070] Optionally, in order to improve the efficiency of the rotating member 132 driving the target film to move, multiple rotating members 132 can also be arranged at positions such as inside the ramp section.

[0071] Optionally, considering that after the film is discharged, due to the influence of inertia, the film may continue to move, resulting in the unfavorable situation that the position of the film is inaccurate during feeding. Therefore, the film feeding mechanism can further include: a positioning member 170, which is arranged at the first edge of the discharge position D away from the placement table 110. The positioning member 170 is set as at least one protruding member, and the protruding member is used to limit the movement of the target film moving to the discharge position D pointing to the first edge based on the protruding structure. Corresponding positioning members 170 can be arranged at the first edge of the discharge position D away from the placement table 110. The positioning member 170 can be one or more protruding members, and the protruding member can be structures such as a protruding square, a protruding triangle, a protruding origin, etc. The specific placement position and placement quantity of the protruding member can be determined according to the shape of the film and the discharge position D, so as to limit the target film moving to the discharge position D from continuing to move in the direction of the first edge according to its protruding structure. The position of the film after discharging can be constrained by the positioning member 170, effectively improving the problem of inaccurate film position.

[0072] Optionally, the pressing member 120 can include: a pressing plate 121 and a spring assembly 122. Among them, one end of the spring assembly 122 is connected to the housing 140, and the other end is connected to the pressing plate 121. The contact surface of the pressing plate 121 in contact with the film is set to conform to the shape of the ramp section. The spring assembly 122 is used to expand and contract according to the quantity of the film to give a constant pressure to the pressing plate 121. The pressing plate 121 is used to press the film toward the ramp section based on the constant pressure to fix the absolute position between the film and the placement table 110.

[0073] Among them, the pressure member 120 can be composed of a spring assembly 122 and a pressing plate 121 to generate corresponding changes according to the changes of the film material. In order to adapt to the placement situation of the film material on the slope section of the placement table 110, the contact surface between the pressing plate 121 and the film material base can be set to conform to the shape of the slope section, so as to generate pressure to fix the film material by conforming to the slope section, improving the effectiveness of the downward pressure. Optionally, the slope section of the placement table 110 can also be set as a table structure with an adjustable inclination angle. Correspondingly, the pressing plate can also be set as a plate structure with an adjustable angle to meet the pressure requirements of various different angles.

[0074] Moreover, since there are quantity changes in the film material during the discharging process, in order to apply sufficient pressure to the film material during the overall discharging process, the spring assembly 122 can expand and contract according to the quantity of the film material. For example, when the film material becomes less, the spring assembly 122 can elongate to apply a constant pressure to the pressing plate 121, so that the pressing plate 121 presses the film material towards the slope section based on the constant pressure, providing sufficient downward pressure for the film material to fix the absolute position between the film material and the placement table 110, effectively ensuring the stability of the discharging process.

[0075] Exemplarily, the spring assembly 122 can be set as a spring with an adjustment function such as a hydraulic spring.

[0076] It should be noted that the pressure of the pressing plate 121 does not change with the change of the quantity of the film material, but provides a constant pressure, and the constant pressure can be determined according to the quantity and thickness of the film material.
