Description

Technical Field

[0001] The utility model relates to a cotton bale wrapping and tucking corner device, and also relates to a cotton bale wrapping and sealing system equipped with the cotton bale wrapping and tucking corner device. Background Art

[0002] The baler on the cotton bale processing production line needs to cover the cotton bales after baling. There are two main types of cotton bags used, one is cotton bagging and the other is plastic bagging. The appearance of plastic bagging is mainly used to realize the automation of cotton bag covering. At the same time, in order to meet the realization of automatic bagging of cotton bagging, some cotton bagging currently has hot melt adhesive sheets at the predetermined position of the bag mouth to facilitate the picking of cotton bagging. Overall, given that fewer and fewer workers can be invested in the cotton processing production line, the automation of the cotton processing production line is an inevitable direction.

[0003] Unlike manual sealing (specifically, manually sewing the bale with needle and thread), the bottom of the cotton bale cover can be tucked in. On the cotton processing production line, when the automatic bale sealing method is used, it is dangerous to manually tuck the corners of the cotton bales. If the corners are tucked after the bale is sealed, the bag surface in the tuck area will collapse due to lack of support, and most of the bag surface is tightly combined with the cotton bale, making it difficult to tuck the corners, and the quality of the tuck will be affected. Specifically, it is difficult to tuck the bag corners to the inside of the belt surface. In general, the cotton bale cover is tightly combined with the cotton bale, and it is usually necessary to use a bale cover when tucked. The cotton bale cover is first put on the bale cover, and the cotton bale will enter the cotton bale cover when passing through the bale cover. In this process, the cotton bale cover will be expanded due to the entry of the cotton bale, and the air in the cotton bale cover has not been discharged. At this time, the bag surface has not collapsed and is suitable for tucking. However, the cotton bale has not yet completely entered the cotton bag, that is, the bagging equipment is still operating normally. If the corners are removed manually, there is a possibility of collision with the moving equipment.

[0004] In some cotton mills, in order to achieve online tucking, it is often necessary to arrange a worker on each side of the bale cover. When the cotton bale passes through the bale cover and enters the cotton bag, the worker uses the tucking tool to push the cotton bag inward from both sides of the bottom of the cotton bag until the cotton bale is completely inside the cotton bag. The worker can then remove the corresponding tool. This manual tucking method is not only labor-intensive and has the possibility of injury, but also can only determine the tucking position completely by senses, and the quality of the tucking is difficult to guarantee.

[0050] For the convenience of description, the cotton bale itself will be explained below. Cotton bales are the output of the baler on the cotton processing production line. The lint cotton is baled by the baler to become a standard cotton bale with the size and weight of a standard cotton bale. The size of the standard cotton bale is 140×70×53, unit: cm, and the deadweight is 227±10kg. It can be seen that the lint cotton in the cotton bale is relatively dense. In addition, on the bale sealing line, in order to improve stability, a surface defined by 140×70 (unit: cm) is generally used as the bottom surface, and supported on the bale sealing line, and the side of 140cm is used as the long side. The conveying direction of the cotton bale is adapted to the long side of the cotton bale. Under this condition, the left and right sides of the cotton bale are the cotton bale surfaces defined by 140×53 (unit: cm). At the same time, it can also be seen that the cotton bale is roughly a rectangular solid structure.

[0051] The aforementioned length, left and right are commonly used reference systems on the production line. Specifically, the conveying direction is the reference direction, which is also called the front-to-back direction. The front-to-back direction is also called the head-to-tail direction, longitudinal direction or length direction in the mechanical field. The left-right direction is also called the width direction and the transverse direction.

[0052] For cotton bale bagging, it has relatively typical bag body characteristics, with a bag opening and a bag bottom, the bag bottom is also called the bag tail, and the bag opening is also called the bag head.

[0053] When wrapping, the cotton bag is usually put on the wrapper manually or by machine with the bag opening as the insertion port. The wrapper is roughly a rectangular tube structure or equivalent to a rectangular tube to match the shape of the cotton bale. When wrapping, the bale pushing device pushes the cotton bale forward in the wrapper along the length of the cotton bale. Since the wrapper and the cotton bale have relatively good fit, specifically, the cross-section of the inner cavity of the traditional wrapper is roughly a rectangle of 140×70 (unit: cm), and the cotton bale roughly fits the four sides of the inner cavity of the wrapper to ensure that the cotton bale fits the cotton bale after being inserted into the cotton bag. During the cotton bale pushing process, the empty space of the cotton bag will produce a volume change, that is, as the cotton bale is inserted, the air in the cotton bag is compressed, and the bag shows that the part that is not currently inserted by the cotton bale is inflated, especially the tail of the cotton bag.

[0054] As the cotton bale moves forward, the front end of the cotton bale contacts the bottom of the cotton bale cover. As the cotton bale moves forward, the cotton bale cover is separated from the cover device due to the force of the cotton bale moving forward. The cover is completed and then the cotton bale is sealed. Generally, the corner of the cotton bale cover needs to be tucked before sealing, and the corner is usually tucked during the cover process.

[0055] Regarding cotton bagging, whether it is plastic bagging or cotton bagging, it is a sheet-shaped body in the storage and transportation state. Specifically, its two large bag surfaces (140×70 bag surface, unit: cm) are attached to each other to form a sheet, and the remaining bag surfaces are often folded onto the sheet. In some implementations, the left and right bag surfaces (140×53, unit: cm) are also formed, which is more common in plastic bagging, but in more applications, cotton bagging is mainly formed by two sheets [(140+26.5)×70, unit: cm] sealed on two long sides and one short side, and the remaining side corresponds to the bag opening, and the sealed short side is the bag tail. In this way, when the rectangular cotton bag is put into the cotton bag bag, the left and right sides of the bag tail will show a relatively obvious triangle structure wrap angle. The tuck angle is mainly for the wrap angle of the triangle structure, specifically tuck it into the bottom bag surface of the cotton bag bag and the cotton bag.

[0056] It needs to be explained again that if the cotton bale is fully put in place, because in general it is necessary to use the forward force of the cotton bale to put the cotton bale into the cotton bale bag and then further push the cotton bale bag off the baling device, the cotton bale and the bottom of the cotton bale bag are tightly combined. In other words, if the cotton bale is fully put in place, it will become very difficult to tuck the corners. Therefore, it is recommended that the cotton bale tucking device work to tuck the corners when the middle and rear part of the cotton bale bag swells after the cotton bale is put into the cotton bale bag, and the cotton bale tucking device is reset after the cotton bale is put into the final position of the cotton bale bag.

[0057] In addition, the cotton bale bag is usually not completely covered on the cover, and usually a length of no less than 20 cm is left. The first function of the cover is to open the cotton bale bag to facilitate the insertion of the cotton bale. At the same time, the cotton bale bag and the cover are often tightly combined. Based on friction or an additional pressure device, when only part of the cotton bale bag is covered on the cover, it can still have a good combination effect. Under the condition of pushing the cotton bale in, it will not fall off the cover prematurely. Therefore, the tail end of the left part is the setting position of the cotton bale cover corner device.

[0058] In an embodiment of the utility model, the provided cotton bale tucking device is arranged at the rear side of the bale wrapper and located on both sides of the cotton bale running path, and has a left tuck assembly 4 and a right tuck assembly 9 based on the running direction of the cotton bale.

[0059] The left tuck corner assembly 4 and the right tuck corner assembly 9 are arranged at both sides of the end of the package platform in a bilaterally symmetrical manner, and the symmetry plane is the bilaterally symmetrical middle plane of the package platform.

[0060] Furthermore, the actuation directions of the tuck actuating parts adapted to the left tuck corner assembly 4 and the right tuck corner assembly 9 are opposite, satisfying the action mode of the left and right facing tuck corners.

[0061] Since the left wing corner assembly 4 and the right wing corner assembly 9 are arranged in a roughly symmetrical manner, and their structural configurations are basically the same except for the different actuation directions, therefore, in the following text, except for the basic structure, the left wing corner assembly 4 will be mainly described, and the right wing corner assembly 9 will refer to the structure, construction, function, etc. of the left wing corner assembly 4.

[0062] Regarding the basic structure, let's first look at the left yoke assembly 4. The left yoke assembly 4 has a left frame and a left yoke actuating part installed on the top of the left frame. The left yoke actuating part includes a left yoke pusher head and a left linear drive mechanism that drives the left yoke pusher head.

[0063] The top of the left frame is roughly consistent with the center line of the side of the tail of the cotton bale bag in the up and down directions.

[0064] It should be noted that, although in the preferred embodiments of the utility model the left frame and the right frame are both an assembly containing movable parts, in some embodiments, the left frame and the right frame can be fixed frames, especially when the tuck pusher head has a buffer device in the front and rear directions (with the bagging platform as a reference datum). At this time, the movement to open the cotton bale conveying path can be completely realized by, for example, the left tuck actuator.

[0065] As described in the background technology section, when tucking the corners manually, the corners can be tucked directly by hand or with the help of a tuck component. In other words, the tuck component belongs to the existing technology. Under this condition, the basic movement form of the tuck pusher is a horizontal linear movement in a direction perpendicular to the side of the cotton bale. It can also be seen from this that before tucking the corners, the tuck component must leave a predetermined distance between the cotton bale bagging, otherwise there will be no starting space for the tuck action. In other words, in the initial state, the tuck component is disengaged from the cotton bale bagging. Therefore, in the reset state, the cotton bale tucking device is disengaged from the cotton bale after the bagging. Even if there is no other part for disengaging the cotton bale tucking device from the cotton bale conveying path, the normal operation of the cotton bale will not be affected by the action of the left linear drive mechanism used to drive, for example, the left tuck pusher. Therefore, both the left frame and the right frame can be fixed frames.

[0066] The advantage of using machines instead of manual labor is manifested in the embodiments of the present invention in that once the positions of the left frame and the right frame on the machine are determined, they are usually stable, while manual labor is more unstable. Although people can foresee the operation mode of the machine and the running path of the moving parts in most of the time, they are limited by their physical strength and energy, and are prone to operating errors, which may cause injuries.

[0067] Correspondingly, the right tuck assembly has a right frame, and a right tuck actuating part installed on the top of the right frame, and the right tuck actuating part includes a right tuck push head and a right linear drive mechanism driving the right tuck push head. As mentioned above, the right tuck assembly is roughly arranged in a left-right symmetrical manner with the left tuck assembly, and the structural configuration is also basically the same.

[0068] Among them, the left frame and the right frame are used to determine the position and height of the tuck corner on the bale sealing system. The position mainly refers to the position of the tuck corner on the cotton bale conveying path, or the front and back position.

[0069] In the following text, for the sake of convenience and to avoid misunderstanding, the left and right yoke assemblies are collectively referred to as yoke assemblies, and the left and right frames are collectively referred to as frames. Other parts that exist symmetrically on the left and right are collectively referred to as such, which are not limited by specific directional terms such as left and right.

[0070] As mentioned above, when the cotton bale is tucked, it has not been completely put into the cotton bale bag. At this time, with the help of the characteristic of the cotton bale causing the middle and rear part of the cotton bale bag to swell during the bagging process, the left tuck assembly and the right tuck assembly press the rear part of the cotton bale bag in the middle of the up and down direction, and press the corners on both sides of the tail of the cotton bale bag. Then, the cotton bale moves forward further and hits the left tuck assembly and the right tuck assembly, so that the left tuck pusher and the right tuck pusher are sandwiched between the front end of the cotton bale and the bottom bag surface of the cotton bale bag. At this time, the left tuck assembly and the right tuck assembly can be reset. However, in this process, the cotton bale will continue to move forward for a certain distance after hitting the corresponding tuck assembly to ensure that the cotton bale is tightly combined with the bottom of the cotton bale bag.

[0071] Correspondingly, a left buffer assembly is provided to provide buffering in the direction of cotton bale conveying, which is also the direction of cotton bale wrapping. Therefore, when the cotton bale collides with the left wrapping assembly during the wrapping process, the left corner pusher head is subjected to force and the left buffer assembly retracts under the impact to achieve buffering.

[0072] At the same time, as mentioned above, during the bagging process, with the introduction of the cotton bale, the air in the cotton bale bag is compressed and leaks out through the cloth surface of the cotton bag or is discharged outward through the preset holes on the plastic bag. However, in this process, the middle and rear part of the cotton bale bag will expand. Under this condition, for example, the left tuck pusher of the left tuck assembly presses the middle part of the left side of the rear part of the cotton bale bag from the left to the right in the vertical direction and waits for the cotton bale to arrive. Finally, the cotton bale reaches the bottom of the bag, for example, the left tuck pusher is also pushed to the bottom of the bag, and the tuck and folding are completed in this process, so that the left tuck pusher cooperates with the bagging force under the action of the left buffer assembly (which determines the folding stroke) to achieve the tuck.

[0073] Based on this, it can also be known that the buffering of the left buffer assembly has a distance, which depends on the distance between the initial position of the tuck corner and the bottom of the cotton bale bag, and is generally 5~20cm.

[0074] Similarly, the right tuck assembly also includes a right buffer assembly for providing buffering in the cotton bale wrapping direction to achieve the tuck in coordination with the wrapping force.

[0075] In view of the relatively large impact force of the cotton bale, the left buffer assembly and the right buffer assembly should have relatively good reliability in the preferred embodiment, and the stiffness coefficient of the buffer is not required to be high. It can even be said that it is sufficient to meet the corresponding conditions such as the left tuck pusher and the right tuck pusher to be able to reset, rather than resisting the impact force of the cotton bale. In other words, the corresponding left buffer assembly, for example, only needs to meet the reset of the left tuck pusher. Its design basis is relatively clear and will not be repeated here. At this time, the first thing to consider for the left buffer assembly and the right buffer assembly is that when facing the impact of the cotton bale during the bagging, it is preferably with good collimation, which can effectively reduce the possibility of damage to the cotton bale bagging tuck device.

[0076] Correspondingly, the corresponding tuck angle assembly is first installed on the corresponding frame using a guide pair to ensure the alignment and reduce the deflection of the corresponding tuck angle push head.

[0077] A buffer component or a buffer piece is further provided, which is arranged between the corresponding tuck assembly and the corresponding frame. When the corresponding tuck assembly is pushed due to the movement of the cotton bale, the tuck assembly moves along the guide pair, and the buffer component or the buffer piece is compressed. When the tuck pusher is reset and the tuck pusher is withdrawn from the cotton bale running path, the tuck assembly is reset in the cotton bale conveying direction.

[0078] Figure 3 and Figure 4 The illustrated structure provides a composite guide, wherein the sliding linear rail pair 44 shown in the figure provides a first guide, and the guide rod and guide hole pair formed by the double-headed screw 454 and the guide hole seat 466 constitutes a second guide. The first guide and the second guide cooperate to provide a more reliable guide.

[0079] Among them Figure 4 The double-headed screw 454 shown in FIG. 1 has two threads to make the guiding more reliable.

[0080] Figure 4 In the embodiment, the stud bolt 454 is a specific example. The stud screw 454 can also be a single-head bolt, the bolt head of the single-head bolt is used as an example. Figure 5 The limiting head on the side of the middle guide hole seat 466.

[0081] Correspondingly, a guide hole 467 is formed on the guide hole seat 466. In some embodiments, the guide hole 467 may also be inlaid with an inner bushing, such as a tin bronze bushing, to reduce friction.

[0082] In addition, the guide hole 467 can also be used as a bottom hole, and a guide sleeve is installed separately, and a linear bearing is installed on the guide sleeve to form a guide rod and guide sleeve pair.

[0083] Among them, Figure 5 As shown, it is a schematic diagram of the structure of a flip arm 46. In the figure, the upper end of the flip arm 46 has an assembly hole 465, through which the statically set track block of the sliding linear track pair 44 is installed. The seat plate 421 is installed with the cylinder body of the tuck cylinder 32 by bolts or screws, and then, for example, the double-headed screw 454 is fixed on the seat plate 421.

[0084] Figure 3 In the figure, the tuck angle cylinder 42 and the roller tuck angle push head 41 constitute a tuck angle assembly, in which the tuck angle cylinder 42 is fixed on a tuck angle frame 43, and the tuck angle frame 43 is fixedly connected to the linear guide rail that determines the sliding linear rail pair 44 shown in the figure, and the linear guide rail is guided on the track block with a track groove.

[0085] The body of the flip arm 46 can also directly form the track groove.

[0086] Figure 3 In the present invention, the sliding linear rail pair is also a rail pair having two parallel arranged rail components, and the guiding reliability is relatively good.

[0087] In addition, if Figure 3 and Figure 4 In the illustrated structure, one end of the double-headed screw 454 is adapted with a locking nut 452 and a rubber pad 453, wherein the locking nut 452 is used to adjust the double-headed screw 454 to provide a fixed length, that is, to adjust the distance between the seat plate 421 and the guide hole seat 466, thereby adjusting the buffer distance.

[0088] The rubber pad 453 is used for buffering when the push head assembly is reset, and is located on the first side of the guide hole seat 466, which is opposite to the side where the seat plate 421 is located. Therefore, when the tuck angle assembly is reset, the rubber pad 453 is located between the locking nut 452 and the guide hole seat 466 to produce a reset buffer.

[0089] As mentioned above, for example, the spring coefficient of the reset spring 455 mounted on the double-headed screw 454 is relatively small, that is, it only needs to satisfy the reset of the tuck angle assembly, and the locking nut 452 is easy to loosen. Figure 4 The illustrated structure also provides a back-tightening nut 451 , which is used to back-tighten the locking nut 452 after it is adjusted into place, so as to improve the anti-loosening capability of the locking nut 452 .

[0090] Regarding preventing the locking nut 452 from loosening, a first set screw hole may be further opened on the side of the locking nut 452 so that the locking nut 452 can be locked using a first set screw (a set screw is commonly known as a top screw, also known as a machine screw) after being adjusted into place.

[0091] In addition, if Figure 4In the structure shown, the seat plate 421 is used for installing the tuck cylinder 42, and the seat plate 421 and Figure 4 The slide 431 shown in FIG. is fixedly connected to each other, and the slide 431 is Figure 3 The slide 431 on the yoke angle frame 43 is connected with the Figure 3 The slide rails of the slide rail pair 44 shown in FIG. 1 are fixedly connected.

[0092] about Figure 4 The buffer assembly composed of the double-headed screw 454 and the like shown in the figure can also be directly replaced by finished parts, such as spring guide pillars.

[0093] In addition, regarding the tuck cylinder 42, Figure 3 It can be seen that it is a double-rod cylinder, which has good guiding performance itself and is used to make, for example, the roller-type corner push head run more smoothly.

[0094] In some embodiments, Figure 1 and Figure 2 The illustrated structure, in addition to the functional part for realizing the tuck corner, also includes a buffer part and a part for flipping the two tuck corner assemblies, so as to swing the two tuck corner assemblies to a predetermined position to fully clear the travel path of the cotton bale.

[0095] For the sake of convenience, the mechanism used to swing the tuck angle assembly to a predetermined position to clear the cotton bale's travel path is collectively referred to as a yielding mechanism. The yielding mechanism includes the left frame and the right frame. The two frames can share one yielding mechanism or each can be configured with a yielding mechanism. If each is configured with a yielding mechanism, the two yielding mechanisms are driven synchronously.

[0096] Synchronous drive can be based on the synchronization of the power machine. For example, when two flip cylinders 1 are used to drive separately, the two flip cylinders can use the same compressed air intake pipeline for air supply. Synchronization can also be achieved in the transmission part of the rear stage of the power machine, for example, using the same transmission shaft. Figure 1 The flip shaft 5 is a driving shaft, and both ends of the driving shaft are used to connect the flip arm 46. The flip shaft 5 is a synchronous shaft.

[0097] The use of the same power machine is conducive to simplifying the structure, especially for the package packaging equipment, whose main frame is often a welded frame, and the corresponding space under the workbench is relatively large, and there is a large free space. Therefore, a synchronous axis such as the flip axis 5 is provided, and only one power machine can be used to drive the two flip arms 46.

[0098] Accordingly, the bearing of the tilting shaft 5 is mounted on a predetermined frame. Figure 1 and Figure 2In the illustrated structure, the tilt shaft 5 is supported by a main bearing 3 and a secondary bearing 7 , wherein the main bearing 3 is mounted on the main leg 2 , and the secondary bearing 7 is mounted on the secondary leg 8 .

[0099] The main supporting legs 2 and the auxiliary supporting legs 8 can be installed on the main frame of the packaging and encapsulating equipment, and can also be installed on the floor of the workshop.

[0100] Considering that the swing angle range required for the left and right tuck assemblies to completely clear the cotton bale's travel path does not need to be too large, the flip axis 5 does not need to realize a turnover, and only needs an angle not greater than 180°, and generally greater than or equal to 90°. This type of movement is called swing in the mechanical field.

[0101] Furthermore, a flipping drive mechanism is provided to output and drive the flip shaft 5 to flip, so that the left tuck corner assembly and the right tuck corner assembly installed on the flip shaft 5 are flipped to achieve displacement.

[0102] The displacement is the position change of the left tuck assembly and the right tuck assembly. The first position is the working position, that is, the turning shaft 46 is roughly in a vertical state, so that, for example, the roller tuck pusher 41 is roughly aligned with the side center line of the tail of the cotton bag; the second position is the storage position, at which the left tuck assembly and the right tuck assembly are roughly completely out of the conveying path of the cotton bale. The displacement is, for example, the displacement of the left tuck assembly between the first position and the second position.

[0103] It should be noted that swing drive is a better choice. In other embodiments, the displacement can be achieved based on lifting, such as Figure 3 The flip arm 46 in the figure can be a lifting arm, so that it can be driven by a lifting drive mechanism to achieve displacement.

[0104] Both the flipping drive mechanism and the lifting drive mechanism are common drive mechanisms in the mechanical field. In the embodiments of the utility model, for example, the flipping drive mechanism is selected in the realization of the displacement of the tuck corner assembly, and does not involve changes to the flipping drive mechanism itself.

[0105] One of the most common choices is the triangle mechanism. Figure 1 The triangular mechanism shown is used to drive the tilting shaft 5 to swing. The triangular mechanism is the most common mechanism used to achieve swinging in the mechanical field. For example, a dump truck uses a triangular mechanism to achieve the swinging of the carriage.

[0106] The triangular mechanism includes a main linear drive mechanism and a crank arm 6 mounted on the flip shaft 5 . Accordingly, the output component of the main linear drive mechanism is hingedly mounted on the crank arm 6 .

[0107] The crank arm 6 is a rocker in the triangular mechanism. Figure 7In the illustrated structure, one end is used for hinged installation with, for example, a push rod mainly used for the tilting cylinder 1, and the seat end of the tilting cylinder 1 is hinged installation on a predetermined frame.

[0108] Figure 7 In the figure, one end of the crank arm 6 has a hinge hole 61 for hinged installation with, for example, a push rod of the flip cylinder 1, and the other end has a second rotating shaft hole 63, and the second rotating shaft hole 63 has a second keyway 63 for circumferential connection with the flip shaft 5 through a key.

[0109] In some embodiments, the flipping drive mechanism can use a gear rack mechanism, the corresponding gear uses the flipping axis 5 as the gear axis, the corresponding rack is engaged with the gear, and is driven by the main linear drive mechanism, that is, the rack can be driven by, for example, a cylinder.

[0110] As an additional note, for example, a pneumatic cylinder is typically characterized by a fast response speed, and the working medium used is air, so even if there is a gas line leak, no pollution will occur.

[0111] In addition, the flip axis 5 can also be directly driven by a rotation drive mechanism, such as a crank rocker mechanism, in which the rocker constitutes the crank arm 6 and the crank can be driven by a servo motor.

[0112] In addition, in some implementations, the swinging may also be directly provided by a power machine, such as a swing motor or a swing cylinder.

[0113] As a form of synchronous driving, the flip driving mechanism is located in the middle of the flip shaft 5 , and the power for flipping the flip shaft 5 is introduced from the middle of the flip shaft 5 .

[0114] Furthermore, the turning shaft 5 has a bearing seat at each end of the turning shaft 5. Figure 1 and Figure 2 The split bearing seat is arranged on the middle main support leg 2. Figure 1 and Figure 2 In the illustrated structure, the bearing seat also includes a bearing seat located in the middle of the flip shaft 5 and on both sides of the flip drive mechanism. Figure 1 and 2 A split bearing seat is installed on the upper end of the auxiliary support leg 8.

[0115] As described above, the left tuck corner pusher and the right tuck corner pusher can be selected from known auxiliary manual tuck corner pushers. In the embodiment of the present utility model, a pusher is also provided, which is described in detail in Figure 6 middle, Figure 6 In the embodiment, the push head has a wedge-shaped head 415, which is roughly an isosceles triangle structure, with rounded top corners and a thickness that gradually increases from the top corner to the bottom edge.

[0116] In order to reduce the difficulty of withdrawing the tucked corner pusher after tucking the corner, a rolling friction part is provided. The rolling friction part is a roller 413 installed at the tail or middle of the wedge head 415 or a ball installed on the joint surface of the wedge head 415. The joint surface of the wedge head 415 is the surface that is engaged with the bag surface of the cotton bag.
