[0043] Installation platform 6. Detailed Implementation

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] This technical solution provides an automatic tube shrinking machine, including a feeding mechanism 1, a feeding mechanism 2, a positioning mechanism 3, a tube shrinking mechanism 4, and a discharging mechanism 5. The feeding mechanism 1, the feeding mechanism 2, and the positioning mechanism 3 are connected end to end along the tube feeding direction. The tube shrinking mechanism 4 and the discharging mechanism 5 are respectively installed on adjacent sides of the positioning mechanism 3, and the working end of the tube shrinking mechanism 4 faces the positioning mechanism 3. The discharging mechanism 5 is used to unload the tube after shrinking from the positioning mechanism 3.

[0046] The feeding mechanism 2 includes a conveyor chain 21, a pushing assembly 22, a feeding plate 23, a receiving seat 24, and a conveying cylinder 25; the feeding end of the loading mechanism 1 is connected to the loading end of the conveyor chain 21; the pushing assembly 22 and the feeding plate 23 are respectively disposed on both sides of the feeding end of the conveyor chain 21, and the pushing assembly 22 is used to push the pipe towards the feeding plate 23; the top of the receiving seat 24 is provided with a receiving groove for accommodating the pipe, and the feeding end of the feeding plate 23 is connected to the receiving groove; the positioning mechanism 3 and the conveying cylinder 25 are respectively disposed at both ends of the extending direction of the receiving groove, and the conveying cylinder 25 is used to push the pipe towards the positioning mechanism 3.

[0047] While existing tube shrinking machines can meet basic usage requirements, their drawbacks are still quite obvious. The main problem is that in actual use, the tube feeding and unloading processes are all done manually. This not only reduces the processing efficiency of the tube shrinking machine but also consumes a lot of manpower and can easily cause personal injury during the tube shrinking process.

[0048] To achieve automated feeding, shrinking, and unloading of pipes, this technical solution proposes an automatic pipe shrinking machine, such as... Figure 1-11 As shown, the automatic pipe shrinking machine includes a feeding mechanism 1 for feeding pipes, a feeding mechanism 2 for conveying pipes to a positioning mechanism 3, a positioning mechanism 3 for positioning and clamping the pipes to be shrunk, a pipe shrinking mechanism 4 for shrinking the pipes, and a unloading mechanism 5 for unloading the shrunk pipes from the positioning mechanism 3. In this automatic pipe shrinking machine, each of the four steps—pipe feeding, feeding, shrinking, and unloading—has a corresponding action mechanism, thereby achieving full automation of the pipe shrinking process and reducing labor costs.

[0049] Specifically, to ensure the smooth operation of the four steps of loading, feeding, tube shrinking, and unloading, and to avoid material blockage, this solution also includes structural improvements to the feeding mechanism 2, which transports the tube from the loading mechanism 1 to the positioning mechanism 3. Figure 2-3 As shown, the device includes a conveyor chain 21, a pushing assembly 22, a feeding plate 23, a receiving seat 24, and a conveying cylinder 25. The feeding process is implemented in the following steps: First, the pipe is fed from the feeding mechanism 1 to the conveyor chain 21, and under the drive of the conveyor chain 21, the pipe is transported to the pushing station of the pushing assembly 22. Then, the pushing assembly 22 acts on the pipe and pushes it to the feeding plate 23, while rolling along the feeding plate 23 to the receiving groove of the receiving seat 24 (not shown in the figure). Since the positioning mechanism 3 and the conveying cylinder 25 are respectively set at both ends of the extension direction of the receiving groove, the pipe is finally pushed to the positioning mechanism 3 under the action of the conveying cylinder 25, completing the transfer of the pipe from the feeding mechanism 1 to the positioning mechanism 3.

[0050] Furthermore, the feeding mechanism 2 also includes a counting component 26;

[0051] The counting assembly 26 includes a counting base 261, a movable counting plate 262, and a counting sensor 263. The counting base 261 is fixedly installed in the middle of the conveyor chain 21 and is located between the feeding mechanism 1 and the pushing assembly 22. The movable counting plate 262 is rotatably installed in the counting base 261 on the side facing the feeding mechanism 1, and the pivot of the movable counting plate 262 is located in the middle of the movable counting plate 262, and the end of the movable counting plate 262 is located above the conveyor chain 21. The counting sensor 263 is installed on the upper part of the counting base 261, and the detection end of the counting sensor 263 faces the upper part of the movable counting plate 262.

[0052] To improve the controllability of the automatic tube shrinking machine and further ensure smooth operation between corresponding steps of each mechanism, this solution also adds a counting component 26 to the feeding mechanism 2 for counting the conveyed tubes, such as... Figure 4 As shown.

[0053] When the pipe passes through the counting assembly 26 driven by the conveyor chain 21, since the end of the movable counting plate 262 is located above the conveyor chain 21, the movable counting plate 262 will move as the pipe moves. Figure 4 The tube is rotated in the direction indicated by the arrow, causing the upper part of the movable counting plate 262 to misalign with the counting sensor 263. When the tube passes through the counting assembly 26, the movable counting plate 262 resets, at which point the detection end of the counting sensor 263 re-moves the upper part of the counting plate 262. Thus, by misaligning and resetting the upper part of the movable counting plate 262 with the detection end of the counting sensor 263, the tube can be counted, allowing technicians to monitor the operation of the automatic tube shrinking machine and improving its controllability.

[0054] Furthermore, the counting component 26 also includes an error prevention barrier 264;

[0055] The anti-error stop bar 264 is installed on the upper part of the counting base 261, and the anti-error stop bar 264 is located on the side of the counting base 261 facing the unloading end of the conveyor chain 21; the end of the anti-error stop bar 264 faces the movable counting plate 262, and the anti-error stop bar 264 is used to prevent the upper part of the movable counting plate 262 from rotating towards the unloading end of the conveyor chain 21.

[0056] As a preferred embodiment of the above solution, this solution also adds an error-prevention baffle 264 to the counting component 26 to prevent the movable counting plate 262 from rotating excessively during the reset process and causing it to align with the counter. Figure 4Rotate in the opposite direction indicated by the arrow to prevent the counting sensor 263 from counting repeatedly.

[0057] Furthermore, the feeding mechanism 2 also includes an anti-drop baffle 27, which and the feeding mechanism 1 are respectively disposed on both sides of the feeding end of the conveyor chain 21. The anti-drop baffle 27 is used to prevent the pipe from falling off the conveyor chain 21.

[0058] In addition, the feeding mechanism 2 of this solution is also equipped with a drop prevention baffle 27, which is used to prevent the pipe from falling off the conveyor chain 21, thereby ensuring the effective transmission of the pipe from the loading mechanism 1 to the feeding mechanism 2.

[0059] To further explain, the pushing assembly 22 includes a pushing cylinder 221, a pushing plate 222, an L-shaped baffle 223, and a positioning detector 224; the pushing cylinder 221 is located on one side of the unloading end of the conveyor chain 21; the pushing plate 222 is connected to the output end of the pushing cylinder 221, and the extending direction of the pushing plate 222 is parallel to the extending direction of the conveyor chain 21; the L-shaped baffle 223 is detachably installed on the side of the pushing plate 222 facing the unloading plate 23, and the blocking end of the L-shaped baffle 223 protrudes above the transmission chain 21; the positioning detector 224 is installed on the top of the L-shaped baffle 223, and the positioning detector 224 is electrically connected to the pushing cylinder 221, and the positioning detector 224 is used to detect the positioning status of the pipe at the loading end of the unloading plate 23.

[0060] In a preferred embodiment of this technical solution, the pushing assembly 22 includes a pushing cylinder 221, a pushing plate 222, an L-shaped baffle 223, and a position detector 224. The pushing process is implemented according to the following steps: First, the pipe is conveyed to the front side of the pushing plate 222 by the drive of the conveyor chain 21, and the pushing position of the pipe is determined by the blocking end of the L-shaped baffle 223. After the position detector 224 located at the top of the L-shaped baffle 223 detects the position of the pipe, the pushing cylinder 221 drives the pushing plate 222 to extend forward and push the pipe to the lower plate 23, thus completing the pushing process. The structure is simple and the performance is reliable.

[0061] To further explain, the feeding plate 23 includes a feeding plate body 231, a fixed limiting strip 232, a movable limiting strip 233, and a feeding detector 234; the feeding plate body 231 is obliquely mounted between the pushing assembly 22 and the receiving seat 24; the fixed limiting strip 232 and the movable limiting strip 233 are parallel to each other and protrude from the plate surface of the feeding plate body 231, and the extension direction of the fixed limiting strip 232 is perpendicular to the extension direction of the conveyor chain 21; the movable limiting strip 233 is detachably installed on the feeding plate body 231, and a rolling feeding space for the pipe is formed between the fixed limiting strip 232 and the movable limiting strip 233; the feeding detector 234 is installed on the top of the movable limiting strip 233, and the detection end of the feeding detector 234 faces the plate surface of the feeding plate body 231.

[0062] In another preferred embodiment of this technical solution, the feeding plate 23 includes a feeding plate body 231, a fixed limiting strip 232, a movable limiting strip 233, and a feeding detector 234. The movable limiting strip 233 allows the feeding plate 23 to adapt to pipes of different lengths, thereby improving the applicability of the feeding plate 23. Furthermore, the fixed limiting strip 232 and the movable limiting strip 233 form a rolling feeding space for the pipe, allowing the pipe to accurately fall into the receiving groove of the receiving seat 24. In addition, the feeding detector 234 installed on the top of the movable limiting strip 233 can count the rolling feeding pipes, enabling technicians to further monitor the operation of the automatic pipe shrinking machine and improve its controllability.

[0063] To further explain, the feeding mechanism 1 includes a feeding box 11 and a feeding seat 12. The feeding seat 12 is installed inside the feeding box 11, and the feeding seat 12 can move up and down at an angle relative to the feeding box 11.

[0064] The top of the feeding box 11 includes a storage section 111 and a stepped feeding section 112 arranged sequentially along the feeding direction of the pipe. The surface of the storage section 111 is inclined downward along the feeding direction of the pipe. The stepped feeding section 112 includes at least three inclined feeding plates, which are parallel to each other. The top height of the three feeding plates increases sequentially along the feeding direction of the pipe. The extension direction of the feeding plates is perpendicular to the inclined direction of the surface of the storage section 111. Feeding gaps are provided between the storage section 111 and the feeding plates, as well as between two adjacent feeding plates.

[0065] The feeding seat 12 includes at least three inclined top plates 120, and the three top plates 120 are parallel to each other. The top height of the three top plates 120 increases sequentially along the feeding direction of the pipe. The top plates 120 are parallel to the feeding plates, and one of the top plates 120 is movably accommodated in a feeding gap.

[0066] In existing technologies, pipe feeding machines typically require technicians to feed each pipe individually, resulting in wasted labor costs and feeding time. Therefore, to achieve efficient pipe feeding in automatic pipe shrinking machines while minimizing human intervention, this technical solution also proposes a feeding mechanism for automatic pipe shrinking machines, such as... Figure 5-7 As shown, it includes a feeding box 11 and a feeding seat 12 that can move up and down at an angle relative to the feeding box 11.

[0067] Specifically, the top of the feeding box 11 of this solution includes a storage section 111 and a stepped feeding section 112 arranged sequentially along the feeding direction of the pipe. The storage section 111 is used by technicians to feed the pipes in piles to the feeding mechanism 1, and the stepped feeding section 112 is used to feed the pipes in piles one by one.

[0068] The following describes the pipe feeding process using a feeding mechanism 1 with a stepped feeding section 112 including three inclined feeding plates and a feeding seat 12 including three inclined top plates 120. The feeding plate closest to the storage section 111 is named the first feeding plate, and the feeding plate furthest from the storage section 111 is named the third feeding plate. The top plate 120 closest to the storage section 111 is named the first top plate, and the top plate 120 furthest from the storage section 111 is named the third top plate.

[0069] In one embodiment, the feeding process of the feeding mechanism 1 is implemented according to the following steps: First, the standby state of the feeding mechanism 1 is as follows: Figure 7 State (a1) and Figure 8 As shown in state (b1), the technicians stack the pipes into the storage section 111. Simultaneously, the pipes roll and accumulate to the top of the first top plate under the action of the inclined surface of the storage section 111; then the first top plate moves upwards at an angle along the feeding gap, as... Figure 7 State (a2) and Figure 8As shown in state (b2), the pipe located at the top of the first top plate rolls sequentially towards the top of the first feeding plate and the second top plate under the action of gravity as it moves upward. Then, the second top plate moves upward at an angle along the feeding gap, causing the pipe located at the top of the second top plate to roll sequentially towards the top of the second feeding plate and the third top plate under the action of gravity as it moves upward. Finally, the third top plate moves upward at an angle along the feeding gap, causing the pipe located at the top of the third top plate to roll towards the top of the third feeding plate and the top of the transmission chain 21 under the action of gravity as it moves upward, thereby realizing the step-by-step feeding of the pipe.

[0070] To further explain, the upper surfaces of both the feeding plate and the top plate 120 are inclined downwards along the feeding direction of the pipe, and the inclination angle of the upper surface of the feeding plate is the same as that of the upper surface of the top plate 120.

[0071] In a preferred embodiment of this technical solution, the upper surfaces of both the feeding plate and the top plate 120 are inclined downward along the feeding direction of the pipe, making it easier for the pipe to roll to the next step during the stepped feeding process, which helps to ensure the realization of step-by-step feeding of the pipe.

[0072] Preferably, the feeding seat 12 further includes a top material connecting plate 121, a feeding driver 122, and a feeding transmission block 123; the top material connecting plate 121 is connected to the end of the top material plate 120, and all the top material plates 120 are connected through the top material connecting plate 121; the feeding driver 122 is disposed inside the feeding box 11, the bottom of the feeding transmission block 123 is connected to the output end of the feeding driver 122, the side wall of the feeding transmission block 123 is connected to the top material plate 120, and the feeding driver 122 is used to simultaneously drive all the top material plates 120 to move within the feeding gap through the feeding transmission block 123.

[0073] In another preferred embodiment of this technical solution, the top material connecting plate 121 is provided so that multiple top material plates 120 can move simultaneously. In this way, the efficiency of step-by-step feeding of pipes can be improved while ensuring that pipes are fed in a stepped manner, and equipment costs can be saved at the same time.

[0074] Preferably, the feeding seat 12 further includes at least two guide rods 124, which are disposed inside the feeding box 11, and the two guide rods 124 are respectively located on both sides of the feeding driver 122; the extending direction of the guide rods 124 is parallel to the moving direction of the top plate 120, the top end of the guide rods 124 passes through the feeding transmission block 123, and the feeding transmission block 123 moves along the extending direction of the guide rods 124.

[0075] In addition, the feeding seat 12 of this solution is also equipped with at least two guide rods 124 to ensure the movement stability of the feeding seat 12 and ensure the effective feeding of pipes in stages.

[0076] Preferably, the feeding mechanism 1 further includes a sliding component 13, which abuts against the feeding box 11 and the feeding seat 12;

[0077] The sliding assembly 13 includes a slide rail 131 and a slider 132, and the slider 132 is slidably mounted on the slide rail 131; the slide rail 131 protrudes from both sides of the inside of the feeding box 11, and the extending direction of the slide rail 131 is parallel to the moving direction of the top plate 120; the slider 132 protrudes from both sides of the outside of the top connecting plate 121, and the outer wall of the slider 132 is provided with a groove for accommodating the slide rail 131.

[0078] Furthermore, this solution also adds a sliding component 13 to the feeding mechanism 1. Through the cooperation of the slide rail 131 and the slider 132, it is more conducive to ensuring the movement stability of the feeding seat 12 and ensuring the effective feeding of pipes step by step.

[0079] Preferably, the feeding mechanism 1 further includes a separating component 14, which is mounted on the top of the feeding box 11 and located above the storage section 111;

[0080] The separating component 14 includes an auxiliary rod 141 and at least one separating plate 142. The auxiliary rod 141 is mounted on the top of the feeding box 11, and the separating plate is detachably installed on the auxiliary rod 141. The separating plate 142 is used to divide the surface of the storage section 111 into multiple storage areas.

[0081] In addition, the present solution also provides a dividing component 14 above the storage section 111 to divide the surface of the storage section 111 into multiple storage areas. On the one hand, it can make the piles of pipes neatly arranged and fed in stages, and on the other hand, it can make the feeding mechanism 1 feed at least two pipes in stages, so as to further improve the feeding efficiency of the feeding mechanism 1.

[0082] To further explain, the positioning mechanism 3 includes a positioning base 31 and a positioning block 32. The positioning block 32 is movably positioned directly above the positioning base 31. The positioning base 31 and the positioning block 32 are used together to position and press the pipe.

[0083] The feeding mechanism 5 includes a feeding seat 51 and a feeding plate 52. The feeding plate 52 is swayably mounted on the top of the feeding seat 51, and the swaying axis of the feeding plate 52 is parallel to the placement direction of the tube in the positioning base 31. The swaying axis of the feeding plate 52 is located in the middle of the bottom surface of the feeding plate 52.

[0084] The material feeding plate 52 includes a material picking end 521 and a material dropping end 522, which are located on both sides of the swing axis of the material feeding plate 52. The material picking end 521 is provided with two material picking arms 5211, which are located at both ends of the positioning base 31. The material picking arms 5211 are used to remove the pipe from the positioning base 31 when the material picking end 521 is tilted upward.

[0085] In the prior art, after the tube is shrunk, it is usually unloaded using common clamping mechanisms such as grippers. However, since the moving path of conventional clamping mechanisms is relatively long, the unloading speed of the tube is slow, which slows down the tube shrinking efficiency of the tube shrinking machine.

[0086] Therefore, in order to improve the pipe feeding speed and prevent it from affecting the operation progress of the automatic pipe shrinking machine, this solution proposes a feeding mechanism 5, which works in conjunction with the positioning mechanism 3 to effectively achieve rapid pipe feeding. Figure 10 As shown. Specifically, when the feeding mechanism 5 is in standby mode, the feeding plate 52 is set horizontally, as shown. Figure 11 As shown in state (c1); its cooperation with the positioning mechanism 3 and the tube shrinking mechanism 4 is realized in the following steps: First, the tube is conveyed from the feeding mechanism 2 to between the positioning base 31 and the positioning block 32, then the positioning block 32 moves downward to press the tube against the positioning mechanism 3; then, the tube shrinking mechanism 4 performs tube shrinking operation on the end of the tube after positioning and pressing; after tube shrinking is completed, the tube shrinking mechanism 4 first disengages from the end of the tube, then the positioning block 32 moves upward and releases the pressing on the tube, then the material picking end 521 of the dropping plate 52 tilts upward, as shown in state (c1); its cooperation with the positioning mechanism 3 and the tube shrinking mechanism 4 is realized in the following steps: First, the tube is conveyed from the feeding mechanism 2 to between the positioning base 31 and the positioning block 32, then the positioning block 32 moves upward and releases the pressing on the tube, then the material picking end 521 of the dropping plate 52 tilts upward, as shown in state (c1); Figure 11 As shown in state (c2), the material-grabbing arm 5211 acts on the shrunken tube and disengages it from the positioning base 31. The tube, now disengaged from the positioning base 31, rolls to the discharge end 522 under the action of the inclined discharge plate 52, thus completing the tube's unloading from the positioning mechanism 3. Compared to the clamping and unloading methods in existing technologies, this solution uses a rolling unloading method to unload the tube, fully utilizing the characteristics of the tube itself, achieving rapid unloading, and offering a simple structure and reliable performance.

[0087] To further explain, the opposing surfaces of the positioning base 31 and the positioning block 32 are both recessed inward, and the positioning base 31 and the positioning block 32 together form a positioning groove for accommodating the pipe, with the working end of the pipe shrinking mechanism 4 facing the end of the positioning groove.

[0088] The tube shrinking mechanism 4 can move horizontally and vertically relative to the positioning base 31.

[0089] In a preferred embodiment of this technical solution, the positioning base 31 and the positioning block 32 together form a positioning groove (not shown in the figure) for accommodating the pipe, which is more conducive to ensuring the positioning and clamping of the pipe in the positioning mechanism 3 and preventing the pipe from shifting during the shrinking process. In addition, the shrinking mechanism 4 can move horizontally and vertically relative to the positioning base 31, so that the shrinking mechanism 4 can be adjusted for pipes of different specifications, thereby further improving the versatility of the automatic shrinking machine.

[0090] It should be noted that the tube shrinking mechanism 4 can move horizontally relative to the positioning base 31, including but not limited to the horizontal movement of the tube shrinking mechanism 4 along the feeding direction of the tube in the positioning mechanism 3, and the horizontal movement perpendicular to the feeding direction of the tube in the positioning mechanism 3.

[0091] Preferably, the positioning mechanism 3 further includes a positioning baffle 33, which is disposed on one side of the positioning base 31 and swings relative to the positioning base 31; the positioning baffle 33 is used to abut against the end of the pipe to prevent the pipe from being conveyed toward the tube shrinking mechanism 4 in the positioning base 31.

[0092] In another preferred embodiment of this technical solution, a positioning baffle 33 is added to the positioning mechanism 3. Its operational relationship with the positioning base 31 and the positioning block 32 is as follows: when the positioning mechanism 3 is in standby mode, the movable end of the positioning baffle 33 is misaligned with the extension direction of the positioning groove, such as... Figure 11 As shown in state (c1); when the pipe is conveyed from the feeding mechanism 2 to the positioning base 31, the positioning baffle 33 first swings downward, and its movable end is opposite to the extension direction of the positioning groove, as shown. Figure 11 As shown in the middle state (c3), the positioning block 32 moves downward to press the tube against the positioning mechanism 3, and the positioning baffle 33 can then be reset upward to prevent it from obstructing the tube shrinking mechanism 4 from shrinking the tube.

[0093] Preferably, the positioning mechanism 3 further includes a rotary motor 34, which is disposed on one side of the positioning base 31. The end of the positioning baffle 33 is detachably installed on the output end of the rotary motor 34, and the positioning baffle 33 swings relative to the positioning base 31 by the rotary motor 34.

[0094] Preferably, the feeding mechanism 5 further includes a feeding drive component 53, which is disposed at the bottom of the feeding plate 52, and the output end of the feeding drive component 53 is connected to the bottom of the feeding end 522. The feeding drive component 53 is used to drive the oscillation of the feeding plate 52.

[0095] Preferably, it also includes an installation platform 6, on which the positioning mechanism 3, the tube shrinking mechanism 4 and the material feeding mechanism 5 are all installed;

[0096] The material feeding drive assembly 53 includes a first hinge seat 531, a telescopic actuator 532, and a second hinge seat 533. The material feeding end 522 of the material feeding plate 52 protrudes from the mounting platform 6. The first hinge seat 531 is mounted on the side wall of the mounting platform 6, and the second hinge seat 533 is mounted on the bottom of the material feeding end 522. The mounting end of the telescopic actuator 532 is hinged to the first hinge seat 531, and the telescopic output end of the telescopic actuator 532 is hinged to the second hinge seat 533. This design simplifies the structure and saves costs while ensuring rapid material feeding.

[0097] Preferably, it also includes a receiving frame, which is located directly below the dropping end 522.

[0098] This solution also includes a receiving frame (not shown in the figure) directly below the material drop end 522 to facilitate the collection of the pipe after the tube shrinkage is completed.
