Description

[0001] This application is a divisional application based on Chinese invention patent application filed by the applicant on August 3, 2018, application number 2018108787916, entitled "External Cutting Fully Automatic Rolling Type Machine", at least part of the original specification is incorporated herein by reference. [Technical Field]

[0002] This invention relates to a fully automatic rolling lettering machine, belonging to the field of pipe fittings production. [Background Technology]

[0003] The fully automated production of roll forming machines requires continuous pipe feeding, and the position of the pipes during feeding must constantly meet the expected settings. Therefore, the feeding accuracy requirements are extremely high. If even one pipe is fed out of order, a large number of pipes in the subsequent batch will become scrap. However, existing roll forming machines often fail to meet the feeding accuracy requirements of pipe production.

[0004] In addition, after the pipe fittings are rolled at the rolling mechanism, they are discharged through the discharge mechanism. It is necessary to avoid accumulation at the outlet of the rolling mechanism. [Summary of the Invention]

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a feeding and discharging device for a fully automatic rolling machine for pipe fittings, ensuring feeding accuracy and fast discharging.

The pipe discharge chute, pipe inlet chute, pipe receiving chute, and second translation mechanism are arranged sequentially along the feeding direction. The vibrating plate sends the pipe to the pipe receiving chute through the pipe discharge chute and pipe inlet chute. After the pipe picker takes the pipe from the pipe receiving chute, it sends the pipe to the rolling plate for rolling through the second translation mechanism. After rolling, the pipe falls naturally from the pipe picker into the discharge port. The discharge mechanism includes a collection funnel, a conveyor belt, and a drive motor that drives the conveyor belt to rotate.

Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0034] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0035] Example

[0036] See Figure 1-13 .

[0037] This embodiment provides an externally cut fully automatic lettering machine, including a pressing mechanism F, a feeding mechanism, a lettering mechanism C, and a discharging mechanism D. The feeding mechanism includes an external feeding mechanism A and an internal feeding mechanism B. The external feeding mechanism A transports the pipe fitting E to the internal feeding mechanism B, which then sends the pipe fitting E to the lettering mechanism C for lettering. After lettering at the lettering mechanism C, the pipe fitting E is discharged through the discharging mechanism D. During the lettering process at the lettering mechanism C, the pressing mechanism F presses down on the pipe fitting E to prevent it from moving during the lettering process.

[0038] The external feeding mechanism A includes a vibratory table A3, a vibratory plate A1, and a pipe fitting discharge trough A2 connected to the discharge port of the vibratory plate A1. The vibratory plate A1 is mounted on the vibratory table A3. The height of the vibratory plate A1 is adjusted by changing the height of the vibratory table A3, thereby adjusting the height of the pipe fitting discharge trough A2. The shape of the trough wall of the pipe fitting discharge trough A2 is set according to the shape of the pipe fitting E to be conveyed. For example, in this embodiment, the pipe fitting E is L-shaped, so the shape of the trough wall of the pipe fitting discharge trough A2 is also designed to be L-shaped, so as to ensure that all pipe fittings E in the pipe fitting discharge trough A2 are transported stably at a specific angle.

[0039] The internal feeding mechanism B includes a first internal feeding mechanism B1 and a second internal feeding mechanism B2. Both the first internal feeding mechanism B1 and the second internal feeding mechanism B2 are mounted on a support table B3. The heights of the first internal feeding mechanism B1 and the second internal feeding mechanism B2 are adjusted via the support table B3 to match the height of the pipe fitting discharge chute A2.

[0040] Specifically, the No. 1 internal feeding mechanism B1 includes a pipe inlet trough B11 and a pipe receiving trough B12 for accommodating and positioning pipe E. The pipe outlet trough A2 is connected to one end of the pipe inlet trough B11, and the other end of the pipe inlet trough B11 is connected to the pipe receiving trough B12. The pipe inlet trough B11 is perpendicular to the pipe receiving trough B12.

[0041] The pipe fitting outlet trough A2 and the pipe fitting inlet trough B11 are arranged in a straight line. The shape of the wall of the pipe fitting inlet trough B11 should be consistent with the shape of the wall of the pipe fitting outlet trough A2. The angle between the pipe fitting inlet trough B11 and the pipe fitting outlet trough A2 is adjusted so that the pipe fitting E can move smoothly from the pipe fitting outlet trough A2 to the pipe fitting inlet trough B11, and then to the pipe fitting receiving trough B12. The pipe fitting E waits in the pipe fitting receiving trough B12 for the second internal feeding mechanism B2 to pick it up. Therefore, in this embodiment, the first internal feeding mechanism B1 is a waiting mechanism relative to the second internal feeding mechanism B2.

[0042] To facilitate smoother feeding of pipe fittings from the inlet trough B11 to the fitting receiving trough B12, a linear vibrator B111 is fixed to the inlet trough B11 in this embodiment. The linear vibrator B111 is located between the tabletop of the support table B3 and the inlet trough B11. A vibrator support plate B112 is fixed to the side of the linear vibrator B111 closest to the tabletop of the support table B3. A vibrator support column B113 is fixed to the tabletop of the support table B3, with its axial direction aligned with the vibration direction of the linear vibrator B111. Simultaneously, the vibration of the linear vibrator B111 causes the vibrator support plate B112 to vibrate, thus allowing the vibrator support column B113 to limit the vibration of the vibrator support plate B112 when the linear vibrator B111 over-vibrates. Therefore, in this embodiment, the vibrator support column B113 is located directly below the vibrator support plate B112.

[0043] The second internal feeding mechanism B2 includes a pipe-receiving connector B21, a first translation mechanism B22, and a second translation mechanism B23. The pipe-receiving connector B21 is mounted on the first translation mechanism B22. Driven by the first translation mechanism B22, the pipe-receiving connector B21 moves into the pipe fitting receiving groove B12 and is inserted into the pipe fitting E. The first translation mechanism B22 is mounted on the second translation mechanism B23. After the pipe-receiving connector B21 is inserted into the pipe fitting receiving groove B12, the second translation mechanism B23 drives the first translation mechanism B22 and the pipe-receiving connector B21, thereby moving the pipe fitting E away from the pipe fitting receiving groove B12 and towards the rolling mechanism C for rolling.

[0044] Specifically, in this embodiment, the rolling mechanism C includes a rolling disk C1 and a rotating mechanism. The rotating mechanism is connected to the rolling disk C1 and drives the rolling disk C1 to rotate. The edge of the rolling disk C1 has a notch, and a character mold C11 matching the shape of the notch is installed in the notch. After the character mold C11 is installed on the rolling disk C1, the rolling disk C1 and the character mold C11 together form a disk. By installing different character molds C11, different characters are rolled onto the pipe E.

[0045] Pipe fitting E moves to the lettering disc C1 under the action of translation mechanism B23. The rotating lettering disc C1 drives the lettering mold C11 to rotate. Translation mechanisms B22 and B23 periodically move pipe fitting E from pipe fitting receiving groove B12 to lettering disc C1, while the lettering mold C11 periodically strikes pipe fitting E. After being lettered, pipe fitting E falls into the discharge mechanism D for finished product collection.

[0046] Therefore, in this embodiment, the vibratory plate A1, the pipe discharge chute A2, the pipe inlet chute B11, the pipe receiving chute B12, the second translation mechanism B23, the roller plate C1, and the discharge mechanism D are arranged sequentially along the feeding direction.

[0047] The working principle of this embodiment is as follows: Pipe E is continuously fed into pipe receiving tank B12 through vibrating plate A1, pipe discharge chute A2, and pipe inlet chute B11. The pipe E in pipe inlet chute B11 squeezes the pipe E in pipe receiving tank B12, ensuring that pipe receiving tank B12 is always filled with material. Pipe connector B21 is used to load material from pipe receiving tank B12, and then the first translation mechanism B22 and the second translation mechanism B23 are used to periodically send pipe E to the rolling plate C1 for rolling. Finally, the finished pipe E is recovered by the discharge mechanism D.

[0048] Preferably, the first translation mechanism B22 includes a first linear actuator B221, a push plate B222, and a connector shaft B223 connected to the push plate B222.

[0049] Linear actuator B221 is fixedly connected to push plate B222, and connector connecting shaft B223 is set perpendicular to push plate B222. Linear actuator B221 pushes push plate B222 in a linear motion, thereby causing connector connecting shaft B223 to move along the driving direction of linear actuator B221. To allow connector connecting shaft B223 to pass through fitting receiving groove B12 and retrieve fitting E, the installation direction of linear actuator B221, i.e., the driving direction, should be perpendicular to fitting inlet groove B11. Connector connecting shaft B223 is set parallel to the installation direction of linear actuator B221. Fitting connector B21 is located at the end of connector connecting shaft B223 furthest from push plate B222, i.e., at the end of connector connecting shaft B223 closest to fitting receiving groove B12. Linear actuator B221, push plate B222, connector connecting shaft B223 and pipe take-up connector B21 are arranged sequentially along the direction perpendicular to the pipe feed groove B11. Linear actuator B221 can be a cylinder or an electric push rod, etc. In this embodiment, a cylinder is selected as linear actuator B221.

[0050] Preferably, the second translation mechanism B23 includes a second linear actuator B231, a slide rail B232, and a sliding plate B233 slidably connected to the slide rail B232. The second linear actuator B231 is connected to the sliding plate B233. The second linear actuator B231 drives the sliding plate B233 to perform linear motion on the slide rail B232.

[0051] Similarly, the second linear actuator B231 can be a cylinder or an electric push rod, etc. In this embodiment, the second linear actuator B231 is a cylinder.

[0052] In this embodiment, both the first linear actuator B221 and the push plate B222 are fixed on the slide plate B233, thereby allowing the first translation mechanism B22 to be mounted on the second translation mechanism B23. Simultaneously, the second linear actuator B231 is perpendicular to the first linear actuator B221, ensuring that the driving direction of the second linear actuator B231 is perpendicular to the driving direction of the first linear actuator B221. Furthermore, the plane formed by the driving directions of the second linear actuator B231 and the first linear actuator B221 should be parallel to the axis of the typesetting disk C1. For example, in this embodiment, the plane formed by the driving directions of the second linear actuator B231 and the first linear actuator B221 is parallel to the tabletop of the support table B3, while the typesetting disk C1 is perpendicular to the tabletop of the support table B3.

[0053] A pipe fitting receiving groove B234 is provided behind the pipe fitting receiving groove B12 along the feeding direction for the sliding of pipe fitting E. The axial direction of the pipe fitting sliding groove B234 is parallel to the slide rail B232. After the pipe fitting connector B21 is inserted into the pipe fitting receiving groove B12, the first linear actuator B221 is reset until the pipe fitting receiving groove B12 and the pipe fitting sliding groove B234 are connected. Then, as the pipe fitting connector B21 moves along the slide rail B232 under the drive of the second linear actuator B231, the pipe fitting E enters the pipe fitting sliding groove B234 and is always positioned by the pipe fitting sliding groove B234, ensuring that the pipe fitting E does not rotate unnecessarily relative to the pipe fitting connector B21 during the movement along the slide rail B232. The shape of the wall of the pipe fitting sliding groove B234 is the same as that of the wall of the pipe fitting receiving groove B12, so that after the pipe fitting sliding groove B234 passes through the pipe fitting receiving groove B12, the pipe fitting E can move smoothly from the pipe fitting receiving groove B12 to the pipe fitting sliding groove B234 without being obstructed.

[0054] To further achieve the positioning of fitting E in fitting receiving groove B12, and thus ensure the stability and accuracy of fitting E acquisition by pipe picker B21 in fitting receiving groove B12, this embodiment sets a base B121 below fitting receiving groove B12. The top of base B121 is fixedly provided with a first receiving groove baffle B125 and a second receiving groove baffle B126 for limiting fitting E. The first receiving groove baffle B125 and the second receiving groove baffle B126 are both parallel to fitting receiving groove B12, and fitting receiving groove B12 is located between the first receiving groove baffle B125 and the second receiving groove baffle B126. Fitting feed groove B11 passes through the first receiving groove baffle B125.

[0055] The first receiving groove baffle B125 has an opening that matches the shape of the wall of the pipe fitting inlet groove B11, so that the pipe fitting E in the pipe fitting inlet groove B11 first passes through the first receiving groove baffle B125 and then enters the pipe fitting receiving groove B12. The second receiving groove baffle B126 prevents the pipe fitting E in the pipe fitting receiving groove B12 from shifting along the axial direction of the pipe fitting inlet groove B11. The pipe fitting E in the first receiving groove baffle B125 is limited by the front and rear compression of the pipe fitting E in the pipe fitting inlet groove B11 and the pipe fitting receiving groove B12 in the axial direction of the pipe fitting inlet groove B11. The pipe fitting E in the first receiving groove baffle B125 is limited by the first receiving groove baffle B125 in the direction perpendicular to the axis of the pipe fitting inlet groove B11, ensuring that the pipe fitting E in the pipe fitting inlet groove B11 can be continuously and accurately fed into the pipe fitting receiving groove B12.

[0056] Since the pipe E being transported in this embodiment is L-shaped, the opening of the pipe E needs to face the pipe pick-up connector B21 so that it can be picked up by the connector B21. Furthermore, the shape of the pipe receiving groove B12, designed to restrict the pipe E, limits its movement within the groove in a direction parallel to the linear actuator B221. Therefore, in order to move the pipe E from the pipe receiving groove B12 to the pipe sliding groove B234, the pipe receiving groove B12 needs to be able to move in a direction parallel to the linear actuator B221.

[0057] As a specific implementation of the above scheme, in this embodiment, the top of the base B121 is provided with a receiving groove B1211 along a direction parallel to the first linear actuator B221. A receiving groove slider B1212 is slidably connected in the receiving groove B1211, and the fitting receiving groove B12 is located on the receiving groove slider B1212. After the pipe connector B21 is inserted into the fitting E, it is reset under the action of the first linear actuator B221. The pipe connector B21 pulls the side wall of the fitting receiving groove B12 through the fitting E, so that the side wall of the fitting receiving groove B12 drives the receiving groove slider B1212 to slide in the receiving groove B1211 until the fitting receiving groove B12 is aligned with the fitting sliding groove B234. Then, under the action of the second linear actuator B231, the pipe connector B21 sends the fitting E from the fitting receiving groove B12 into the fitting sliding groove B234.

[0058] Because the connection between the pipe connector B21 and the pipe fitting E is loose, in order to prevent the pipe connector B21 from leaving the pipe opening of the pipe fitting E, and as an auxiliary power means for the pipe fitting receiving groove B12 to move in a direction parallel to the first linear actuator B221, in this embodiment the receiving groove slider B1212 is connected to the third linear actuator B122, and the third linear actuator B122 is set parallel to the first linear actuator B221.

[0059] The No. 3 linear actuator B122 can be a cylinder or an electric push rod, etc. In this embodiment, the No. 3 linear actuator B122 is a cylinder.

[0060] As a specific form of positioning pipe fitting E by the pipe fitting receiving groove B12, this embodiment has a positioning block for positioning pipe fitting E on the top of the receiving groove slider B1212. There are two positioning blocks, namely positioning block B12123 and positioning block B12124. Positioning block B12123, positioning block B12124 and slide rail B232 are arranged sequentially along the installation direction of linear actuator B221. The pipe fitting receiving groove B12 is located between positioning block B12123 and positioning block B12124. Positioning block B12123 and positioning block B12124 constitute the sidewall of the pipe fitting receiving groove B12 in this embodiment. Positioning block B12123 and positioning block B12124 are both arranged between receiving groove baffle B125 and receiving groove baffle B126. After fitting E is positioned in fitting receiving groove B12, positioning block B12124 engages the corner of fitting E, and positioning block B12123 rests against the wall of fitting E, preventing fitting E from moving in the direction parallel to linear actuator B221 within fitting receiving groove B12. Meanwhile, positioning block B12124 does not interfere with the pipe fitting connector B21's ability to retrieve fitting E.

[0061] In this embodiment, the receiving groove slider B1212 includes an upper receiving groove slider B12121 and a lower receiving groove slider B12122. The lower receiving groove slider B12122 is slidably disposed in the receiving groove slide B1211. The upper receiving groove slider B12121 is installed on top of the lower receiving groove slider B12122. The first positioning block B12123 and the second positioning block B12124 are both disposed on top of the upper receiving groove slider B12121. The lower receiving groove slider B12122, the upper receiving groove slider B12121, the first positioning block B12123, and the second positioning block B12124 are integrally formed. The upper receiving groove slider B12121 is located between the first receiving groove baffle B125 and the second receiving groove baffle B126.

[0062] Preferably, in this embodiment, a lower floating member B12125 is provided on the second positioning block B12124. The lower floating member B12125 is located between the second positioning block B12124 and the slide rail B232. A first reset member is provided between the lower floating member B12125 and the bottom of the sliding block B12121 on the receiving groove.

[0063] Specifically, an opening is provided on the lower slider B12122 of the receiving groove. The lower floating member B12125 can move within this opening in a direction perpendicular to the tabletop of the support table B3. The opening extends to the bottom of the upper slider B12121 of the receiving groove. A portion of the lower floating member B12125 located within the opening is directly below the upper slider B12121 of the receiving groove. A reset member is positioned between this portion of the lower floating member B12125 and the upper slider B12121 of the receiving groove. The portion of the pipe connector B21 near the pipe receiving groove B12 is arc-shaped. The natural height of the lower floating member B12125 should not be too high. As the pipe connector B21 gradually approaches the pipe receiving groove B12, it compresses the lower floating member B12125. The floating member B12125 in its natural state can provide auxiliary restraint for the pipe E in the pipe receiving groove B12. The compressed buoyant element B12125 helps the pipe fitting B21 to be tightened inside the pipe opening of the fitting E.

[0064] Similarly, a top plate is provided at the top of the pipe fitting receiving groove B12, and an upper floating member B12126 is installed on the top plate. The upper floating member B12126 can move relative to the top plate in a direction perpendicular to the tabletop of the support table B3. At the same time, a second reset member is installed between the upper floating member B12126 and the top plate, and the lower end of the upper floating member B12126 is located below the top plate. As the pipe fitting E in the first receiving groove baffle B125 moves towards the empty pipe fitting receiving groove B12, due to the certain curvature of the pipe fitting E itself, it gradually squeezes the lower end of the upper floating member B12126, causing the upper floating member B12126 to move away from the pipe fitting receiving groove B12. Under the action of the second reset member, the upper floating member B12126 positions the pipe fitting E in the pipe fitting receiving groove B12 in a direction perpendicular to the top plate.

[0065] Preferably, both the first and second reset components can be springs.

[0066] Unlike existing technologies, this embodiment has two feeding mechanisms: a left feeding mechanism and a right feeding mechanism. The left and right feeding mechanisms are arranged in a mirror-symmetrical configuration. Correspondingly, there are two scrolling discs C1: a left scrolling disc C12 and a right scrolling disc C13.

[0067] The left rolling plate C12 is located behind the pipe sliding groove B234 of the left feeding mechanism along the feeding direction of the left feeding mechanism, and rolls the pipe E transported by the left feeding mechanism. The right rolling plate C13 is located behind the pipe sliding groove B234 of the right feeding mechanism along the feeding direction of the right feeding mechanism, and rolls the pipe E transported by the right feeding mechanism.

[0068] The rotating mechanism includes a motor C2, a main gear C3, a left driven gear C121, and a right driven gear C131. The motor C2 is connected to the main gear C3 so that the motor C2 drives the main gear C3 to rotate. For example, the motor C2 is connected to the main gear C3 through a rotating shaft.

[0069] The left driven gear C121 and the right driven gear C131 are located on both sides of the main gear C3, and both are meshed with the main gear C3. The main gear C3 simultaneously drives the left driven gear C121 and the right driven gear C131 to rotate. The left driven gear C121 is fixed to the left rolling plate C12, and the right driven gear C131 is fixed to the right rolling plate C13, so as to achieve the purpose of the left driven gear C121 driving the left rolling plate C12 to rotate, and the right driven gear C131 driving the right rolling plate C13 to rotate.

[0070] Specifically, in this embodiment, the left driven gear C121 and the left rolling plate C12 are fixed together by a left rotating shaft C122, and the right driven gear C131 and the right rolling plate C13 are fixed together by a right rotating shaft C132.

[0071] In this embodiment, the main gear C3, the left driven gear C121, the right driven gear C131, the left rotating shaft C122, and the right rotating shaft C132 are all installed in a gearbox C4 so that there will be no relative translational movement between the main gear C3, the left driven gear C121, and the right driven gear C131.

[0072] The ratio of the diameters of the left driven gear C121 and the right driven gear C131 determines their angular velocity ratio, which in turn determines the ratio of the rolling efficiency of the left rolling type disk C12 and the right rolling type disk C13. Simultaneously, to prevent interference between the working processes of the left and right rolling type disks C12 and C13, the ratio of their diameters is also indirectly determined. Therefore, in this embodiment, the diameters of the left driven gear C121 and the right driven gear C131 are chosen to be the same. More preferably, the diameters of the left rolling type disk C12 and the right rolling type disk C13 are the same.

[0073] The reason is that if the diameter ratio of the left driven gear C121 and the right driven gear C131 is different, although the ratio of the rolling efficiency of the left rolling plate C12 and the right rolling plate C13 can be adjusted, this will cause the center of gravity of the entire rotating mechanism to be unstable. At the same time, the force on the edge of the main gear C3 will change greatly with its own rotation, resulting in severe wear of the teeth on the edge of the main gear C3. This will make the rolling efficiency of the left rolling plate C12 and the right rolling plate C13 increasingly uncontrollable, and the scrap volume of the left rolling plate C12 and the right rolling plate C13 will increase simultaneously, resulting in more losses compared to the existing single-sided rolling machine.

[0074] In this embodiment, a mounting plate B31 is fixed on the support table B3, parallel to the tabletop of the support table B3, with a gap between the mounting plate B31 and the support table B3. Both the left and right feeding mechanisms are mounted on the mounting plate B31. Conversely, a gearbox plate C42 is fixed parallel to the top of the mounting plate B31, and a gearbox C4 is fixedly mounted on the gearbox plate C42 to ensure that the rolling disc C1 is positioned above the feeding mechanism. To accommodate the relative position of the gearbox C4 and the support table B3, in this embodiment, a motor C2 is mounted on a motor plate C21, which is mounted on the mounting plate B31, again with a gap between the motor plate C21 and the mounting plate B31.

[0075] In this embodiment, the discharge mechanism D is installed in the gap between the support table B3 and the mounting plate B31. A discharge port B311 is provided on the mounting plate B31. The discharge port B311 is located directly below the left rolling plate C12 and the right rolling plate C13. After the rolling is completed, the pipe E falls naturally from the pipe take-up connector B21 into the discharge port B311.

[0076] The discharge mechanism D includes a collection hopper D1, a conveyor belt D2, and a drive motor D3 that drives the conveyor belt D2 to rotate. The drive motor D3 is connected to the conveyor belt D2, driving the conveyor belt D2 to carry the pipe E to its destination. The upper end of the collection hopper D1 is located directly below the discharge port B311, and the lower end of the collection hopper D1 is connected to the conveyor belt D2. Baffles D4 are provided on both sides of the conveyor belt D2 to prevent the pipe E from falling off the sides of the conveyor belt D2.

[0077] Among them, a baffle plate D5 and a baffle cylinder D6 are fixed at the rear end of the baffle plate D4 along the feeding direction. The baffle plate D5 is fixed on the baffle cylinder D6. Both the baffle cylinder D6 and the baffle plate D5 are located above the conveyor belt D2. The baffle plate D5 intercepts unqualified products under the drive of the baffle cylinder D6.

[0078] In addition, there are two pressing mechanisms F: a left pressing mechanism and a right pressing mechanism. The left pressing mechanism is located next to the left rolling plate C12, and the right pressing mechanism is located next to the left rolling plate C12. Both the left and right pressing mechanisms are fixed on the upper surface of the mounting plate B31, and the left and right pressing mechanisms are mirror-symmetrical.

[0079] In this embodiment, the pressing mechanism F includes a pressing cylinder F1, a pressing shaft F2, a pressing slide rail F3, a first upper pressing plate F4, a first lower sliding plate F5, a second upper pressing plate F6, a second lower sliding plate F7, and a pressing component F8. The pressing cylinder F1 is fixed on the upper surface of the mounting plate B31. The pressing cylinder F1 is fixed to the pressing shaft F2 to drive the pressing shaft F2 away from or towards the rolling disc C1 along the normal direction of the rolling disc C1. The pressing cylinder F1, the first upper pressing plate F4, and the second upper pressing plate F6 are arranged sequentially along the axial direction of the pressing shaft F2, and the pressing shaft F2 passes through the first upper pressing plate F4 and the second upper pressing plate F6. The first upper pressing plate F4 is fixed on the pressing shaft F2, and the second upper pressing plate F6 is movably mounted on the pressing shaft F2 along the axial direction of the pressing shaft F2.

[0080] Upper pressure plate F4 is fixed to the upper surface of lower slide plate F5, and upper pressure plate F6 is fixed to the upper surface of lower slide plate F7. Upper pressure plate F4, lower slide plate F5, upper pressure plate F6, and lower slide plate F7 are all set parallel to mounting plate B31. Upper pressure plate F4 and lower slide plate F5 form sliding group one, and upper pressure plate F6 and lower slide plate F7 form sliding group two. Lower slide plates F5 and F7 are both mounted on pressure rail F3. Sliding group one is fixed to pressure shaft F2, and sliding group two is movable relative to pressure shaft F2 along the axial direction of pressure shaft F2.

[0081] To position the relative roles of the upper pressure plate F4 and the pressure shaft F2 during installation, this embodiment includes a limiting member F21 made of elastic material fixedly mounted on the pressure shaft F2. In this embodiment, the limiting member F21 is selected as a limiting ring. The limiting ring can be made of rubber, plastic, etc.

[0082] A limiting opening F41 is provided on the side wall of the upper pressure plate F4 away from the rolling disc C1. During the installation of the upper pressure plate F4, it is inserted into the end of the pressure shaft F2 near the rolling disc C1. After the upper pressure plate F4 is in contact with the limiting ring, the limiting ring is squeezed to fall into the limiting opening F41, thus achieving the installation positioning effect. At the same time, after the limiting ring falls into the limiting opening F41, the upper pressure plate F4 is fixed to the pressure shaft F2, thereby fixing the sliding assembly to the pressure shaft F2.

[0083] A pin F61 is inserted into the second upper pressure plate F6. The top of the pin F61 protrudes from the upper surface of the second upper pressure plate F6, thus fitting against the upper surface of the second upper pressure plate F6, and the bottom end of the pin F61 protrudes from the lower surface of the second upper pressure plate F6. The upper surface of the second upper pressure plate F6 is the side of the second upper pressure plate F6 away from the pressure rail F3, and the lower surface of the second upper pressure plate F6 is the side of the second upper pressure plate F6 close to the pressure rail F3.

[0084] The top of pin F61 acts as a limit, preventing relative movement between pin F61 and the second upper pressure plate F6 along the axial direction of the pressure shaft F2. A pin groove F22 is provided on the pressure shaft F2 at the position where the second upper pressure plate F6 is installed. The pin groove F22 is arranged along the axial direction of the pressure shaft F2, and the bottom end of pin F61 is located in the pin groove F22. Simultaneously, the length of the pin groove F22 should allow pin F61 to move along the axial direction of the pressure shaft F2, thereby enabling the relative position between the second upper pressure plate F6 and the pressure shaft F2 along the axial direction of the pressure shaft F2 to be adjustable within a certain range.

[0085] The pressure component F8 is fixed on the second upper pressure plate F6.

[0086] When the pressing cylinder F1 drives the pressing shaft F2 to move toward the rolling plate C1, the pin groove F22 approaches the side wall of the pressing cylinder F1 and hits the pin F61, or the first sliding group hits the second sliding group, causing the second sliding group to move toward the rolling plate C1, thereby pressing the pressing component F8 to press the pipe E to be rolled.

[0087] When the pressure cylinder F1 drives the pressure shaft F2 away from the rolling plate C1, the pin groove F22 moves away from the side wall of the pressure cylinder F1 and hits the pin F61, causing the second upper pressure plate F6 to move away from the second lower sliding plate F7 together to reset, so that the pressure component F8 no longer presses the pipe E after the rolling is completed.

[0088] Because the connection between the pipe connector B21 and the pipe E is very loose, after losing the pressure of the pressing component F8 and the support of the pipe sliding groove B234, the pipe E, after the rolling is completed, naturally falls off the pipe connector B21 and into the discharge port B311 under the action of gravity.

[0089] Furthermore, in this embodiment, the pin F61 will not detach from the second upper pressure plate F6 due to gravity. When disassembling or installing the second upper pressure plate F6, simply manually pull out or insert the pin F61 first.

[0090] In this embodiment, the pressing component F8 includes a pressing base F81, a fixed shaft F82, and a pressing plate F83. The pressing base F81 is fixed on the second upper pressing plate F6, and the fixed shaft F82 is axially fixed in the pressing base F81 along the pressing shaft F2. The pressing plate F83 is parallel to the rolling disc C1 and is installed at the end of the fixed shaft F82 away from the pressing cylinder F1.

[0091] In cases other than those described in this embodiment, the pressure base F81 can adjust the height of the pressure plate F83 and the angle of the fixed shaft F82 to accommodate different shaped pipe fittings E and different angles when the pipe fitting E leaves the pipe fitting sliding groove B234.

[0092] Preferably, in this embodiment, the pressure plate F83 is made of nylon to prevent damage to the pipe E when the pressure plate F83 presses against the pipe E.

[0093] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
