Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and more specifically, to an extrusion apparatus. Background Technology

[0002] Adhesive is a substance that firmly bonds two or more materials through surface adhesion. Its core function is to form cohesive and adhesive forces at the interface, thereby resisting separation. In the production process of photovoltaic modules, such as sealing the frame and bonding junction boxes, adhesive is required to achieve the desired process objectives. In related technologies, large-capacity bagged adhesive is widely used due to its cost advantage. Typically, operators repackage bagged adhesive for later use. However, manually squeezing the bags can easily leave adhesive residue, resulting in waste and increased production costs. Utility Model Content

[0003] This application provides an extrusion apparatus to at least address the technical problem that manual extrusion of packaging bags easily leads to glue residue in the bag, causing glue waste and increasing production costs.

[0004] The extrusion apparatus provided in this application includes an extrusion assembly and a winding assembly. The extrusion assembly has an extrusion gap, the size of which is configured to increase or decrease to allow a packaging bag to pass through and be held within the extrusion gap. The winding assembly includes a winding member configured to wind the packaging bag around its outer side. When the winding member winds the packaging bag, the packaging bag moves relative to the extrusion assembly within the extrusion gap, causing the extrusion assembly to extrude the medium from the packaging bag.

[0005] In some embodiments, the extrusion assembly includes two loading members and two extruders. The two loading members are spaced apart along a first direction. The two extruders are rotatably connected to the two loading members at opposite ends, and the two extruders are spaced apart in a second direction perpendicular to the first direction. The extrusion gap includes the gap between the two extruders, and at least one of the two extruders is configured to move relative to the loading members along the second direction to increase or decrease the size of the extrusion gap.

[0006] In some embodiments, the loading member has a moving groove, and the extruder passes through the moving groove, the moving groove being used to guide the extruder to move along the second direction. The extrusion assembly also includes a limiting member, which is connected to the loading member, a portion of the limiting member extending into the moving groove and abutting against the extruder to limit the travel of the extruder along the second direction.

[0007] In some embodiments, the winding member comprises two members configured to jointly clamp and wind the packaging bag. The winding assembly includes two mounting members spaced apart along a third direction, with opposite ends of the winding members rotatably connected to the two mounting members. When the two winding members rotate synchronously relative to the mounting members, they jointly wind the packaging bag.

[0008] In some embodiments, the two winding members include a first winding member and a second winding member. The opposite ends of the first winding member are rotatably connected to the two mounting members, respectively. The second winding member is disposed on the first winding member and configured to move relative to the first winding member to switch between a first state and a second state. In the first state, the extension directions of the first winding member and the second winding member intersect, and the packaging bag can extend between the first winding member and the second winding member. In the second state, the extension directions of the first winding member and the second winding member are the same, and the first winding member and the second winding member together clamp the packaging bag.

[0009] In some embodiments, the first winding member is provided with a first connector and a second connector; the second winding member includes a first end and a second end opposite to each other in the third direction, the first end is connected to the first connector, the second end is connected to the second connector, and the second winding member is configured to rotate about the first end and drive the second end away from or towards the first winding member, so that the second winding member switches between the first state and the second state.

[0010] In some embodiments, the end of the second connector remote from the first winding member is provided with a connecting groove. The winding assembly further includes a first knob and a second knob. The first knob is connected through the first end and the first connector, and is configured to lock or unlock the first end and the first connector. The second knob is connected through the second end and the second connector, and is configured to lock or unlock the second end and the second connector. The opening of the connecting groove is configured to allow the second knob to disengage from or extend into the connecting groove in the first state and the second state.

[0011] In some embodiments, the first end is provided with a first mounting groove, at least a portion of the first connector is accommodated in the first mounting groove, and the first knob is connected through the two side walls of the first mounting groove and the first connector; the second end is provided with a second mounting groove, at least a portion of the second connector is accommodated in the second mounting groove, and the second knob is connected through the two side walls of the second mounting groove and the second connector.

[0012] In some embodiments, the extrusion apparatus further includes a support assembly configured to mount the extrusion assembly and the winding assembly, the support assembly having a clearance space for accommodating a storage element configured to store the extruded medium in the packaging bag, the clearance space being opposite the extrusion assembly in the height direction of the support assembly.

[0013] In some embodiments, the support assembly includes a main body and a support column, the main body having the clearance space. The support column is connected to the main body and includes a first side and a second side facing away from each other. The extrusion assembly and the winding assembly are located on the first side, and the isolation assembly of the extrusion device is located on the second side.

[0014] In the extrusion apparatus of this application embodiment, the packaging bag can pass through and be clamped in the extrusion gap. When the winding member winds the packaging bag, the packaging bag moves relative to the extrusion assembly in the extrusion gap so that the extrusion assembly expels the medium (such as glue) in the packaging bag. This allows the medium in the packaging bag to be completely extruded, reducing waste and lowering production costs. At the same time, compared with manual extrusion of the packaging bag, the extrusion apparatus makes the extrusion process more time-saving and labor-saving, and the operation difficulty and intensity are lower.

[0032] Adhesive is a substance that firmly bonds two or more materials through surface adhesion. Its core function is to form cohesive and adhesive forces at the interface, thereby resisting separation. In the production process of photovoltaic modules, such as sealing the frame and bonding the junction box, adhesive is required to achieve the desired process. In related technologies, large-capacity bagged adhesive is widely used due to its cost advantage. Typically, operators repackage bagged adhesive for later use. However, manually squeezing the packaging bag can easily leave adhesive residue inside, resulting in waste and increased production costs. To solve the above problems, please refer to [link to relevant documentation]. Figure 1 and Figure 6 This application provides an extrusion apparatus 100.

[0033] Please see Figure 1 and Figure 2 The extrusion apparatus 100 provided in this application includes an extrusion assembly 10 and a winding assembly 30. The extrusion assembly 10 has an extrusion gap 101, the size of which is configured to be able to increase or decrease so that a packaging bag can pass through and be held in the extrusion gap 101. The winding assembly 30 includes a winding member 31, which is configured to be able to wind the packaging bag around the outside of the winding member 31. When the winding member 31 winds the packaging bag, the packaging bag moves relative to the extrusion assembly 10 in the extrusion gap 101 so that the extrusion assembly 10 extrudes the medium in the packaging bag.

[0034] The extrusion device 100 is a structure used to mechanically pressurize a packaging bag to extrude the medium inside the packaging bag. Specifically, when the packaging bag is placed in a preset position on the extrusion device 100 by manual operation or by a mechanical device such as a robotic arm, the extrusion device 100 can apply a squeezing force to the packaging bag to extrude the medium inside the packaging bag.

[0035] Packaging bags are flexible containers made of plastic, fiber, metal, or composite materials. They can be used to hold, protect, store, and transport various media. Different materials can be selected to make packaging bags depending on the media they contain. Packaging bags are deformable under external forces, which facilitates folding and storage, and ensures that the media inside is completely squeezed out.

[0036] The medium can be a solid medium and / or a liquid medium. Solid media include, but are not limited to, metals, ceramics, plastics, rubber, and fibers; liquid media include, but are not limited to, pure liquids (such as water, mercury, etc.), solutions (such as salt water, acids, alkalis, etc.), and colloids (such as glue, paint, etc.). For ease of understanding, the following embodiments use glue as an example. In this case, the packaging bag can be a plastic bag, which can be made of at least one of the following materials: plastic, aluminum foil, etc.

[0037] The extrusion assembly 10 is a component in the extrusion device 100 used to mechanically pressurize the packaging bag. Specifically, when the size of the extrusion gap 101 increases, the packaging bag can pass through the extrusion gap 101 manually or mechanically; when the size of the extrusion gap 101 decreases, the packaging bag can be clamped in the extrusion gap 101 by the extrusion assembly 10 and can be compressed. That is, the size of the extrusion gap 101 is adjustable. This allows the extrusion assembly 10 to adapt to packaging bags of different thicknesses, improving its applicability; on the other hand, by adjusting the gap size, the extrusion force applied by the extrusion assembly 10 to the packaging bag can be controlled, preventing excessive extrusion force from causing damage to the packaging bag, and preventing insufficient extrusion force from preventing the medium in the packaging bag from being completely emptied.

[0038] In some embodiments, the size of the extrusion gap 101 can be adjusted manually, which can reduce the production cost of the extrusion assembly 10. In other embodiments, the size of the extrusion gap 101 can be adjusted automatically by machinery, which can improve the size adjustment accuracy and avoid the problem of uneven extrusion force on the packaging bag due to uneven size of the extrusion gap 101, thus improving the stability and reliability of the extrusion assembly 10.

[0039] The winding assembly 30 is a component in the extrusion device 100 used to wind the packaging bag, thereby driving the packaging bag to move relative to the extrusion assembly 10 in the extrusion gap 101, and continuously winding the extruded packaging bag. The winding member 31 is a structure in the winding assembly 30 used to connect with the packaging bag. The winding member 31 can be a roller, a shaft, or the like. Specifically, when the winding member 31 is connected to the tail end of the packaging bag (the end opposite to the open end of the packaging bag), and the winding member 31 rotates (spins), the winding member 31 can wind the packaging bag and drive the packaging bag to move relative to the extrusion assembly 10 in the extrusion gap 101. In this case, the packaging bag can undergo axial (length direction of the packaging bag) stretching movement in the extrusion gap 101, while being radially (thickness direction of the packaging bag). That is, the packaging bag undergoes continuous deformation of thickness compression and length extension in the extrusion gap 101. Thus, the packaging bag can push the medium to be extruded under the geometric constraints of the extrusion gap 101.

[0040] In some embodiments, the winding member 31 can be manually driven to wind the packaging bag. Specifically, the extrusion device 100 may further include an operating member 70, which is connected to one end of the winding member 31 and configured to rotate under force to drive the winding member 31 to rotate. The operating member 70 is a component in the extrusion device 100 that is manually operated to drive the winding member 31 to wind the packaging bag. The operating member 70 can be a manual crank, a manual wheel, or a combination of a manual wheel and a wheel handle, etc. When force is manually applied to the operating member 70, the operating member 70 rotates under force and drives the winding member 31 to rotate, so that the winding member 31 winds the packaging bag. The manual driving method eliminates the need for a motor and control system, resulting in a simple structure and low cost.

[0041] In other embodiments, the winding member 31 can wind the packaging bag under mechanical drive. Specifically, the extrusion device 100 can also automatically control the rotation of the winding member 31 via a motor, servo system, or pneumatic device to enable the winding member 31 to wind the packaging bag. The mechanical drive method reduces manual intervention and facilitates automated production.

[0042] In the extrusion apparatus 100 of this embodiment, the packaging bag can pass through and be clamped in the extrusion gap 101. When the winding member 31 winds the packaging bag, the packaging bag moves relative to the extrusion assembly 10 in the extrusion gap 101, so that the extrusion assembly 10 extrudes the medium (such as glue) in the packaging bag. This allows the medium in the packaging bag to be completely extruded, reducing waste and lowering production costs. At the same time, compared with manually extruding the packaging bag, the extrusion apparatus 100 makes the extrusion process more time-saving and labor-saving, with lower operation difficulty and intensity. In addition, compared with manually extruding the packaging bag to squeeze out the glue inside, the extrusion apparatus 100 can also reduce the possibility of human contact with glue, reducing the harm of glue to the human body.

[0043] Please see Figure 1 and Figure 2 In some embodiments, the extrusion assembly 10 includes two loading members 11 and two extruders 13. The two loading members 11 are spaced apart along a first direction X. The two extruders 13 are rotatably connected to the two loading members 11 at opposite ends, and the two extruders 13 are spaced apart in a second direction Y perpendicular to the first direction X. The extrusion gap 101 includes the gap between the two extruders 13, and at least one of the two extruders 13 is configured to be movable relative to the loading members 11 along the second direction Y to increase or decrease the size of the extrusion gap 101.

[0044] The loading member 11 is a structure in the extrusion assembly 10 used to load components such as the extruder 13. The loading member 11 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. For example, the loading member 11 can be made of aluminum alloy, which increases its structural strength and reduces the possibility of deformation and damage. Two loading members 11 are spaced apart along a first direction X, allowing them to jointly install and fix the extruder 13, ensuring stable installation and improving the stability and reliability of the extrusion assembly 10. The extruder 13 is a structure in the extrusion assembly 10 used to directly contact the packaging bag and apply extrusion force to it. The extruder 13 is spaced apart along a second direction Y, with the gap between the two extruder 13 in the second direction Y being the extrusion gap 101. The extension direction of the extruder 13 is parallel to the first direction X, and the extension directions of the two extruder 13 are parallel. The extruder 13 can rotate relative to the loading member 11 to accommodate the entry and exit of the packaging bag.

[0045] Specifically, in some embodiments, at least one of the two extruders 13 can move relative to the loading member 11 along the second direction Y to increase or decrease the size of the extrusion gap 101. That is, at least one of the two extruders 13 can move relative to the loading member 11 along the second direction Y, so that the two extruders 13 move away from or closer to each other, thereby making the size of the extrusion gap 101 adjustable. This allows adjustment of the extrusion force of the extrusion assembly 10 on the packaging bag. The smaller the size of the extrusion gap 101, the greater the extrusion force; the larger the size of the extrusion gap 101, the smaller the extrusion force. This improves the applicability of the extrusion assembly 10, making it suitable for packaging bags of different thicknesses. On the other hand, it prevents excessive extrusion force from causing damage to the packaging bag, while also preventing insufficient extrusion force from preventing the medium in the packaging bag from being completely emptied.

[0046] Understandably, during the adjustment of the extrusion gap 101, the extension directions of the two extruders 13 can remain parallel, thus ensuring that the packaging bag clamped between the two extruders 13 is subjected to uniform force, so that the medium in the packaging bag can be completely extruded, thereby improving the extrusion effect.

[0047] In this embodiment, the example is given where both extruders 13 can move relative to the loading member 11 along the second direction Y to increase or decrease the size of the extrusion gap 101. Specifically, both extruders 13 can move to achieve size adjustment, which improves the flexibility of size adjustment and facilitates operation, while also improving the efficiency of size adjustment.

[0048] Please see Figure 2 In some embodiments, the loading member 11 is provided with a moving groove 111, and the extruder 13 passes through the moving groove 111. The moving groove 111 is used to guide the extruder 13 to move along the second direction Y. The extrusion assembly 10 also includes a limiting member 15, which is connected to the loading member 11. A portion of the limiting member 15 extends into the moving groove 111 and abuts against the extruder 13 to limit the travel of the extruder 13 along the second direction Y.

[0049] Thus, the setting of the limiting member 15 can limit the movement stroke of the extruder 13 along the second direction Y, thereby limiting the maximum size of the extrusion gap 101 and preventing the size of the extrusion gap 101 from increasing during the operation of the extrusion assembly 10, which would cause the medium in the packaging bag to not be completely extruded, thereby ensuring the extrusion effect of the extrusion device 100.

[0050] Specifically, in some embodiments, the limiting member 15 includes, but is not limited to, a push rod or a knob. In this case, the limiting member 15 can be manually driven to push the extruder 13 to move in the moving groove 111 along the second direction Y, so that the two extruders 13 move away from or closer to each other, thereby increasing or decreasing the extrusion gap 101.

[0051] For example, the two extrusion members 13 include a first extrusion member and a second extrusion member, which are spaced apart along the second direction Y. The two limiting members 15 include a first limiting member and a second limiting member. The first limiting member can cooperate with the first extrusion member, and the second limiting member can cooperate with the second extrusion member. For the first limiting member, it can pass through the loading member 11 along the second direction Y and partially extend into the moving groove 111, and abut against the first extrusion member. For the second limiting member, it can pass through the loading member 11 along the second direction Y and partially extend into the moving groove 111, and abut against the second extrusion member. When the first limiting member is subjected to force and moves in the direction from the second extruder to the first extruder (parallel to the second direction Y), and / or when the second limiting member is subjected to force and moves in the direction from the first extruder to the second extruder (parallel to the second direction Y), the two extruders 13 can move away from each other to increase the size of the extrusion gap 101; when the first limiting member is subjected to force and moves in the direction from the first extruder to the second extruder, and / or when the second limiting member is subjected to force and moves in the direction from the second extruder to the first extruder, the two extruders 13 can move closer to each other to decrease the size of the extrusion gap 101.

[0052] In other embodiments, the limiting member 15 can be a push rod or a cylinder piston rod, etc. In this case, the limiting member 15 can push the extruder 13 to move along the second direction Y under mechanical drive. For example, the limiting member 15 can push the extruder 13 to move along the second direction Y under the action of a device such as an electric push rod or a cylinder, so that the two extruders 13 move away from each other or closer to each other, thereby increasing or decreasing the extrusion gap 101.

[0053] In some embodiments, the loading member 11 is further provided with a mounting port 113 communicating with the moving groove 111. The mounting port 113 is configured to allow the extruder 13 to detach from or extend into the moving groove 111. Thus, the mounting port 113 facilitates the loading and unloading of the extruder 13 on the loading member 11, improving assembly efficiency.

[0054] Specifically, in some embodiments, the extruder 13 includes an extrusion body and protrusions disposed at opposite ends of the extrusion body. The extrusion body is located between two loading members 11, and the protrusions are movably inserted into the moving groove 111. The limiting member 15 can abut against the protrusions to limit the movement stroke of the extruder 13 along the second direction Y. The mounting port 113 is located at the top of the loading member 11 in the height direction Z (perpendicular to the first direction X and the second direction Y) of the extrusion assembly 10. This facilitates the protrusions to detach from or be inserted into the moving groove 111 through the mounting port 113, improving assembly efficiency. Furthermore, it prevents the extrusion assembly 10 from detaching from the moving groove 111 through the mounting port 113 during operation, improving the stability and reliability of the extrusion assembly 10.

[0055] It is understood that the cross-sectional dimension of the extrusion body cut by a plane perpendicular to the first direction X is greater than the cross-sectional dimension of the protrusion cut by a plane perpendicular to the first direction X; the dimension of the protrusion in the second direction Y is basically the same as the dimension of the mounting port 113 in the second direction Y, ensuring that the protrusion can be inserted into the moving groove 111 through the mounting port 113.

[0056] Please see Figure 1 and Figure 2 In some embodiments, the extrusion apparatus 100 further includes an isolation assembly 50, which includes an isolation roller 51 and an isolation film 53 wound on the isolation roller 51. The isolation film 53 is configured to be wound around the outer periphery of the extruder 13 to prevent contact between the extruder 13 and the medium.

[0057] This prevents glue from sticking to the extrusion component 13, such as preventing glue from sticking to the opening of the packaging bag at the end of the extrusion process. This allows for the smooth progress of subsequent extrusion work and also saves time on manual cleaning of the extrusion component 10.

[0058] Specifically, in some embodiments, the isolation assembly 50 may further include two isolation supports 55, which are spaced apart and used together to load the isolation roller 51. Before extrusion begins, the operator can remove the extruder 13 from the loading member 11 and remove the isolation roller 51 from the isolation support 55. Then, the isolation film 53 on the isolation roller 51 is wound around the outer periphery of the extruder 13, and finally the extruder 13 is loaded onto the loading member 11. It should be noted that in some embodiments, the material of the isolation film 53 includes, but is not limited to, polyethylene, polypropylene, and polytetrafluoroethylene. The isolation film 53 needs to have good anti-stick properties to ensure that the medium is difficult to adhere to.

[0059] In some embodiments, an isolation layer (such as an organosilicon coating, PET coating, etc.) is provided on the outer peripheral wall of the extrusion 13. The isolation layer has better anti-stick properties, which can reduce the adhesion of glue to the extrusion 13 and facilitate the subsequent cleaning of the extrusion 13.

[0060] Please see Figure 2 In some embodiments, the winding member 31 includes two members configured to jointly clamp and wind the packaging bag. The winding assembly 30 includes two mounting members 33 spaced apart along a third direction A. The opposite ends of the winding member 31 are rotatably connected to the two mounting members 33, and the two winding members 31 jointly wind the packaging bag when they rotate synchronously relative to the mounting members 33.

[0061] Specifically, in some embodiments, the two winding members 31 can clamp the packaging bag to achieve a connection between the winding member 31 and the packaging bag. The mounting member 33 is a structure in the winding assembly 30 used to load components such as the winding member 31. The mounting member 33 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. For example, the loading member 11 can be made of aluminum alloy, which increases the structural strength of the loading member 11 and reduces the possibility of deformation and damage. The two mounting members 33 are spaced apart along a third direction A, so that the two mounting members 33 can jointly install and fix the winding member 31, ensuring a stable installation and improving the stability and reliability of the winding assembly 30.

[0062] In some embodiments of this application, the third direction A is parallel to the first direction X, which can prevent the packaging bag from twisting and deforming between the winding member 31 and the extrusion assembly 10 during the winding process of the winding member 31 winding the packaging bag, thereby reducing the possibility of damage to the packaging bag and ensuring that the winding member 30 can stably wind the packaging bag so that the extrusion assembly 10 can extrude the medium in the packaging bag.

[0063] Please combine Figure 3 and Figure 5 In some embodiments, the two windings 31 include a first winding 311 and a second winding 313. The opposite ends of the first winding 311 are rotatably connected to two mounting members 33, and the second winding 313 is disposed on the first winding 311 and configured to move relative to the first winding 311, in a first state ( Figure 3 (as shown) and the second state ( Figure 5The system switches between the two states. In the first state, the extension direction of the first winding member 311 intersects the extension direction of the second winding member 313, and the packaging bag can be inserted between the first winding member 311 and the second winding member 313. In the second state, the extension direction of the first winding member 311 is the same as the extension direction of the second winding member 313, and the first winding member 311 and the second winding member 313 together hold the packaging bag.

[0064] Understandably, when the winding member 31 can rotate under manual driving, the operating member 70 can be connected to the first winding member 311. Thus, when the operating member 70 is rotated under force and drives the first winding member 311 to rotate relative to the mounting member 33, the second winding member 313 can rotate together with the first winding member 311 relative to the mounting member 33. That is, the first winding member 311 and the second winding member 313 can rotate synchronously to achieve the winding of the packaging bag.

[0065] The second winding 313 can switch between a first state and a second state under manual or mechanical intervention. Manual intervention may include: manually operating the second winding 313; or manually operating the second winding 313 with the aid of tools; mechanical intervention may include: operating the second winding 313 with a robotic arm or other mechanical device.

[0066] Specifically, in some embodiments, the first state may be the state of the second winding member 313 when the second winding member 313 moves relative to the first winding member 311, and the extension direction of the first winding member 311 intersects the extension direction of the second winding member 313; the second state may be the state of the second winding member 313 when the second winding member 313 moves relative to the first winding member 311, and the extension direction of the first winding member 311 is the same as the extension direction of the second winding member 313. For example, when the second winding member 313 is manually operated, it can move away from or towards the first winding member 311 to switch between the first and second states.

[0067] In the first state, the extension direction of the first winding member 311 intersects the extension direction of the second winding member 313. At this time, there is a large gap between the first winding member 311 and the second winding member 313, which facilitates the insertion of the packaging bag between the first winding member 311 and the second winding member 313. In the second state, the extension direction of the first winding member 311 is the same as the extension direction of the second winding member 313. At this time, the gap between the first winding member 311 and the second winding member 313 is small or approximately zero. Thus, when the packaging bag is located between the first winding member 311 and the second winding member 313, and the second winding member 313 switches to the second state, the first winding member 311 and the second winding member 313 can jointly clamp the packaging bag. Furthermore, in the second state, when the first winding member 311 and the second winding member 313 rotate synchronously, the first winding member 311 and the second winding member 313 can jointly achieve the winding of the packaging bag.

[0068] Please see Figures 2 to 5 In some embodiments, the first winding member 311 is provided with a first connector 35 and a second connector 37. The second winding member 313 includes a first end 3131 and a second end 3133 opposite each other in a third direction A. The first end 3131 is connected to the first connector 35, and the second end 3133 is connected to the second connector 37. The second winding member 313 is configured to rotate about the first end 3131 and drive the second end 3133 away from or towards the first winding member 311, so that the second winding member 313 switches between a first state and a second state.

[0069] In the above embodiments, the first connector 35 and the second connector 37 are both structural components in the winding assembly 30 that enable the second winding member 313 to be connected to the first winding member 311. The first connector 35 and the second connector 37 can be connecting posts or connecting pins, etc. Specifically, when the second winding member 313 rotates around the first end 3131 and drives the second end 3133 away from the first winding member 311, the second winding member 313 can switch from the second state to the first state. In this case, the packaging bag can be inserted between the first winding member 311 and the second winding member 313. When the second winding member 313 rotates around the first end 3131 and drives the second end 3133 closer to the first winding member 311, the second winding member 313 can switch from the first state to the second state. In this case, the first winding member 311 and the second winding member 313 can jointly clamp the packaging bag.

[0070] Understandably, in the first state, the second end 3133 can be separated from the second connector 37, which facilitates the first winding member 311 to switch from the first state to the second state; in the second state, the second end 3133 cannot or is difficult to separate from the second connector 37, which can prevent the second winding member 313 from moving away from the first winding member 311 at the start of winding, causing the packaging bag to fall off the winding assembly 30, thereby ensuring the normal implementation of winding and improving the stability and reliability of the winding assembly 30.

[0071] Please combine Figure 3 and Figure 4 In some embodiments, the end of the second connector 37 furthest from the first winding member 311 is provided with a connecting groove 371. Specifically, in the fourth direction B, the second connector 37 includes a first end and a second end opposite to each other. The first end of the second connector 37 is connected to the first winding member 311, and the second end of the second connector 37 is connected to the second winding member 313. The connecting groove 371 is provided at the second end of the second connector 37. The connecting groove 371 may be recessed from the end face of the second end of the second connector 37 toward the first end of the second connector 37.

[0072] It should be noted that, in some embodiments, the fourth direction B can be: the arrangement direction of the first winding member 311 and the second winding member 313 in the second state, that is, in the second state, the first winding member 311 and the second winding member 313 are arranged side by side along the fourth direction B.

[0073] In some embodiments, the winding assembly 30 further includes a first knob 38 and a second knob 39. The first knob 38 is connected through a first end 3131 and a first connector 35, and is configured to lock or unlock the first end 3131 and the first connector 35. The second knob 39 is connected through a second end 3133 and a second connector 37, and is configured to lock or unlock the second end 3133 and the second connector 37. The opening 3711 of the connecting groove 371 is configured to allow the second knob 39 to disengage from or extend into the connecting groove 371 in a first state and a second state.

[0074] In the above embodiment, the first knob 38 is a structural component in the winding assembly 30 used to connect the second winding member 313 to the first connector 35, and the second knob 39 is a structural component in the winding assembly 30 used to connect the second winding member 313 to the second connector 37. Specifically, when the first knob 38 is rotated to release the locking between the first end 3131 and the first connector 35, and the second knob 39 is rotated to release the locking between the second end 3133 and the second connector 37, the second winding member 313 can rotate around the first end 3131 to move the second end 3133 away from or closer to the first winding member 311. In this case, the second knob 39 disengages from or extends into the connecting groove 371 through the opening 3711 of the connecting groove 371, and the second winding member 313 cuts between the first state and the second state. When the first knob 38 is rotated to lock the first end 3131 and the first connector 35, and the second knob 39 is rotated to lock the second end 3133 and the second connector 37, the second winding member 313 cannot or is difficult to move relative to the first winding member 311. In this case, the second winding member 313 can remain in the second state. Furthermore, when the first winding member 311 rotates and drives the second winding member 313 to rotate synchronously, the first winding member 311 and the second winding member 313 can jointly wind the packaging bag.

[0075] Furthermore, please combine Figure 1 In some embodiments, the first end 3131 is provided with a first mounting groove 3135, at least a portion of the first connector 35 is accommodated in the first mounting groove 3135, and the first knob 38 is connected to the two side walls of the first mounting groove 3135 and the first connector 35; the second end 3133 is provided with a second mounting groove 3137, at least a portion of the second connector 37 is accommodated in the second mounting groove 3137, and the second knob 39 is connected to the two side walls of the second mounting groove 3137 and the second connector 37.

[0076] Specifically, in some embodiments, when at least a portion of the first connector 35 is accommodated within the first mounting groove 3135, the first knob 38 can sequentially pass through one side wall of the first mounting groove 3135, the first connector 35, and the other side wall of the first mounting groove 3135; when at least a portion of the second connector 37 is accommodated within the second mounting groove 3137, the second knob 39 can sequentially pass through one side wall of the second mounting groove 3137, the second connector 37, and the other side wall of the second mounting groove 3137. The first mounting groove 3135 facilitates the connection and positioning of the second winding member 313 and the first connector 35, and the second mounting groove 3137 facilitates the connection and positioning of the second winding member 313 and the second connector 37, thereby improving the assembly efficiency of the winding assembly 30.

[0077] For example, the first knob 38 and the first connector 35 can be connected by a threaded connection, and there is no direct connection between the first knob 38 and the two side walls of the first mounting groove 3135. Thus, when the first knob 38 is rotated to thread the first knob 38 and the first connector 35, the second winding member 313 and the second connector 37 are locked; when the first knob 38 is rotated to disengage the threaded connection between the first knob 38 and the first connector 35, the second winding member 313 and the second connector 37 are unlocked. Similarly, the second knob 39 and the second connector 37 can be connected by a threaded connection, and there can be no direct connection between the second knob 39 and the two side walls of the second mounting groove 3137, or they can be threaded together.

[0078] Please see Figure 1 , Figure 2 and Figure 6 In some embodiments, the extrusion apparatus 100 further includes a support assembly 90 configured to hold the extrusion assembly 10 and the winding assembly 30. The support assembly 90 has a clearance space 901 for accommodating a storage member 300 configured to store the extruded medium in the packaging bag. The clearance space 901 is opposite to the extrusion assembly 10 in the height direction Z of the support assembly 90.

[0079] In the above embodiments, the support component 90 is a structure in the extrusion apparatus 100 used to load components such as the extrusion component 10 and the winding component 30. The support component 90 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. For example, the support component 90 can be made of aluminum alloy, which can improve the structural strength of the support component 90, reduce the possibility of deformation and damage to the support component 90, and ensure the normal operation of the extrusion apparatus 100. In some embodiments of this application, the support component 90 is provided with multiple loading positions for loading the extrusion component 10 and the winding component 30. For example, the extrusion component 10 can be installed in the corresponding loading position by means of the loading member 11, the winding component 30 can be installed in the corresponding loading position by means of the mounting member 33, and the isolation component 50 can be installed in the corresponding loading position by means of the isolation bracket 55.

[0080] It should be noted that the extrusion assembly 10 and the support assembly 90 can be detachably connected, such as by threaded connection, snap-fit ​​connection, or a combination of threaded connection and snap-fit ​​connection; the extrusion assembly 10 and the support assembly 90 can also be non-detachably connected, such as by welding, gluing, or a combination of welding and gluing. The connection methods between the winding assembly 30 and the support assembly 90, and between the isolation assembly 50 and the support assembly 90, are basically the same as the connection method between the extrusion assembly 10 and the support assembly 90, and will not be described again here.

[0081] Storage component 300 is a structure for collecting and storing extruded media from a packaging bag. Storage component 300 can be located on an external bearing surface (e.g., the floor of a factory or warehouse), and can extend into a clearance space 901, facing the extrusion component 10 in the height direction Z of the support component 90, thereby enabling storage component 300 to collect the extruded media from the packaging bag; alternatively, storage component 300 can be mounted on the support component 90, located in the clearance space 901, and facing the extrusion component 10 in the height direction Z of the support component 90, thereby enabling storage component 300 to collect the extruded media from the packaging bag. It is understood that when the media is adhesive, storage component 300 can be a glue bucket. The glue bucket can collect the extruded adhesive from the packaging bag to achieve adhesive recycling, reduce adhesive waste, and lower production costs.

[0082] In some embodiments, in the height direction Z of the support assembly 90, the winding assembly 30 is located on the side of the extrusion assembly 10 opposite to the clearance space 901. Thus, during winding, the packaging bag between the winding assembly 30 and the extrusion assembly 10 can be stretched approximately vertically, resulting in uniform tension distribution and reducing the risk of wrinkles or breakage. Furthermore, in the height direction Z of the support assembly 90, the extrusion assembly 10 is located above the clearance space 901. Thus, when the storage component 300 is housed in the clearance space 901, the medium inside the packaging bag naturally flows downwards under gravity. Simultaneously, the extrusion force of the extrusion assembly 10 is superimposed on gravity, improving the medium extrusion efficiency and reducing medium residue.

[0083] Please combine Figure 6 In some embodiments, the support assembly 90 includes a main body 91 and a support column 93, with the main body 91 having a clearance space 901. The support column 93 is connected to the main body 91 and includes a first side 931 and a second side 933 facing away from each other. The extrusion assembly 10 and the winding assembly 30 are disposed on the first side 931, and the isolation assembly 50 of the extrusion device 100 is disposed on the second side 933.

[0084] Thus, the extrusion assembly 10 and the winding assembly 30 are positioned on the same side of the support column 93, which facilitates their coordinated operation. Specifically, when the winding assembly 30 winds the packaging bag, the extrusion assembly 10 can extrude the medium from the packaging bag, ensuring the stability and reliability of the extrusion device 100. Simultaneously, the isolation assembly 50 is positioned on the second side 933, preventing it from interfering with the winding process of the winding assembly 30 and ensuring the normal operation of the extrusion device 100.

[0085] In some embodiments, the support assembly 90 includes a storage member 95 with a storage cavity 951 for storing the extruder 13 of the extrusion assembly 10. That is, when the extruder 13 is removed from the loading member 11 for maintenance or to wind up a release liner, the extruder 13 can be temporarily stored in the storage cavity 951, reducing the possibility of loss due to careless placement.

[0086] In some embodiments, the support assembly 90 includes a handle 97 for a user to grip and move the extrusion device 100. Specifically, the handle 97 may be mounted on the main body 91, allowing the user to push the extrusion device 100 to the location of the storage unit 300, so that the storage unit 300 enters the clearance space 901. This eliminates the need for the user to repeatedly move the storage unit 300, allowing them to freely move the extrusion device 100 to the location of the target storage unit 300 (e.g., the storage unit 300 requiring additional glue) as needed.

[0087] Furthermore, in some embodiments, the bottom of the support assembly 90 is provided with a rolling element 99, which is rotatable relative to the main body 91. When the extrusion device 100 needs to be moved, the operator can apply force to the extrusion device 100 through the handle 97. At this time, the extrusion device 100 can move under the rotation of the rolling element 99, thereby making the movement of the extrusion device 100 easier. In addition, when the extrusion device 100 does not need to be moved, the rolling element 99 can provide support for the extrusion device 100, preventing the extrusion device 100 from directly contacting the bearing surface (such as the ground) and causing uncleanliness or moisture damage. For example, the rolling element 99 is provided at the bottom of the main body 91. When the cross-sectional shape of the main body 91 is square, there are four rolling elements 99, which are respectively provided at the four corners of the main body 91.
