Description

Technical Field

[0001] The invention relates to the technical field of mechanical packaging, and in particular to a combined packaging and stacking device for cylindrical materials in a factory. Background Art

[0002] With the improvement of industrial automation level and the development of logistics field, in order to realize full automation of production line and improve production efficiency, automatic packaging and palletizing equipment is currently used on production lines to pack, sort and palletize products. Automatic packaging and palletizing equipment detects the position and status of items through sensors, and the control system directs the mechanical structure to perform grabbing, handling and palletizing operations according to preset programs.

[0003] In industry, automatic packaging and palletizing machines are mainly used to stack rectangular objects, while the stacking of cylindrical objects is mostly done manually or using simple molds. Currently, the equipment on the market that can stack cylindrical materials usually uses vertical delivery or clamping methods to pack, bag or wrap, and can only handle a single or single layer of objects at a time. Since the cylinder is easy to roll, the second layer of items tends to slide into the gaps between the first layer of items, resulting in one less item on the second layer than on the first layer. This not only increases the space utilization of the packaging box or bag, but also limits its ability to handle small items. At the same time, there are problems such as slow speed, low precision and large material loss. The prior art has proposed a good solution, such as the cylindrical object stacking and accumulation device with patent publication number CN105110022B, which pushes the material to move by a pushing cylinder, and ensures the stability of the material during the lifting and pushing process by the pushing pressure plate and tension spring on the pushing mechanism. At the same time, the guide plate and guide strip set in the pushing direction of the pushing mechanism are used to separate the material evenly, so as to avoid rolling, accumulation and collision of the goods during the stacking, lifting and pushing process. And the stacking and accumulation box structure using the fence-type middle partition can effectively prevent the cylindrical objects from flipping over during stacking, thereby avoiding affecting the storage and transportation quality.

[0004] Although the prior art solves the problem that cylindrical materials are prone to collapse during storage and stacking, the following problems still exist: although the specifications and models of cylindrical materials are limited, the demand for different lengths leads to a large number of cylindrical materials. If a dedicated packaging and stacking rack is designed for each cylindrical material, not only will the number be huge, but it will also be easy to confuse in actual use, affecting production efficiency and the mold device will occupy production space. In addition, the existing packaging and stacking rack design is relatively universal. For cylindrical materials of various specifications and models (such as Φ159, Φ89, Φ108, etc.), due to the unequal outer diameters, the use of a universal stacking rack will result in irregular stacking, resulting in poor tightening of the strapping belt and easy collapse, thereby affecting storage and transportation quality.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention provides a combined packaging and stacking equipment for cylindrical materials in a factory. Summary of the invention

[0006] The present invention provides a combined packaging and stacking equipment for factory cylindrical materials, which solves the problem that a general stacking frame has irregular stacking shapes for cylindrical materials of different numbers and sizes, resulting in poor packaging effects and affecting storage and transportation. The stacking frame is designed to be a freely adjustable structure, a fixing mechanism is provided to distinguish and buffer each layer of materials for stacking, and an adjusting mechanism is provided to shape and support the cylindrical materials on the bottom layer, thereby ensuring that the cylindrical materials are stacked in a regular shape and form a stable support.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A combined packaging and stacking equipment for cylindrical materials in a factory, comprising a transport mechanism and a grabbing mechanism; further comprising a stacking frame, a fixing mechanism and an adjusting mechanism; the stacking frame is connected to the grabbing mechanism; the fixing mechanism is connected to the stacking frame; the adjusting mechanism comprises an adjusting hole and an adjusting plate; the adjusting hole is arranged on the fixing mechanism; the adjusting plate is connected to the fixing mechanism; the grabbing mechanism grabs the cylindrical material to the stacking frame position, the fixing mechanism on the stacking frame receives the cylindrical material and slowly moves it down to the adjusting mechanism position, the adjusting hole slides open under the downward pressure of the cylindrical material and then contracts and presses the cylindrical material, and the adjusting plate is pressed against the limit adjusting hole by the pressure of the outermost cylindrical material.

[0009] Preferably, the fixing mechanism includes a fixing plate, a separation slot, a separation slider, a separation spring and a connecting assembly; the separation slot is provided on the inner wall of the fixing plate; a plurality of separation sliders are slidably installed in the separation slot; the separation spring and the separation slider are installed at intervals; and the connecting assembly is connected between the separation slider and the adjusting mechanism.

[0010] In the above scheme, the separation sliders are installed on the side walls of the fixed plate, and the separation sliders are arranged in multiple pieces. The separation sliders of each layer have the same angle with the side walls of the fixed plate. When each layer of cylindrical materials is lowered, the outermost cylindrical materials will contact the side walls of the fixed plate when they reach the bottom position. At this time, the separation sliders of the bottom layer will contact the outermost cylindrical materials, so that the cylindrical materials can be clearly layered under the action of the separation sliders when stacking, and due to the action of the separation springs, the lowering of the cylindrical materials can be buffered to avoid impact on the cylindrical materials at the bottom layer and cause collapse.

[0011] Preferably, the fixed plate includes a bottom plate and a support plate; the bottom plate is connected to the stacking frame; the support plate is connected to the bottom plate, and the angle between the bottom plate and the support plate is 120 degrees.

[0012] In the above scheme, in order to ensure stability and reduce the space occupied, cylindrical materials are usually stacked into a hexagonal structure with an inner angle of 120 degrees when stacking. Therefore, the bottom plate and the support plate are fixed to a 120-degree structure, which can provide good support for the stacked cylindrical materials, thereby forming the stack, so that the cylindrical materials in the outer circle can be in tangential contact with the support plate, so that each cylindrical material in the outer circle can be supported, thereby ensuring the stability of the stacking structure.

[0013] Preferably, the adjustment hole comprises an adjustment slot, an adjustment slider and an adjustment spring; the adjustment slot is symmetrically arranged on both sides of the base plate; a plurality of adjustment sliders are slidably installed in the adjustment slot; and the adjustment spring is installed at intervals from the adjustment slider.

[0014] In the above scheme, the adjustment hole is set to a structure that can automatically adjust the size, so that cylindrical materials with different apertures can be placed. Every two adjustment sliders can adjust the distance between the two adjustment sliders by adjusting the elastic force of the spring, so that after the cylindrical material is placed between the two adjustment sliders, the cylindrical material can be clamped by adjusting the elastic force of the spring, thereby ensuring that the cylindrical material will not shake, and increasing the stability of the bottom stacking, ensuring that it can be stacked and formed later, and can adapt to cylindrical materials of different diameters.

[0015] Preferably, a fitting cambered surface is symmetrically arranged on the upper portion of the adjusting slider; the fitting cambered surface is made of rubber material, and when clamping a cylindrical material, the center of the arc line of the cross section of the fitting cambered surface is eccentrically arranged compared to the center of the cross section of the cylindrical material.

[0016] In the above scheme, the fitting arc surface of the rubber material can further improve the stability of the bottom cylindrical material after clamping and fixing, and the rubber material can undergo a certain degree of deformation under the clamping force to maintain fit with the cylindrical material. The rubber material can increase the friction without wearing the surface of the cylindrical material, thereby preventing the cylindrical material from radially sliding under the clamping force; since the curvature radius of the fitting arc surface is greater than the radius of the cylindrical material, in order to ensure that the fitting arc surface can increase the contact area with the cylinder, the center of the arc line of the fitting arc surface cross section is eccentrically set compared to the center of the cross section of the cylindrical material when clamping the cylindrical material, so that each cylindrical material in the bottom layer can be better fixed and the stability is improved.

[0017] Preferably, threaded seats are provided at both ends of the adjusting spring, and the elastic modulus of the adjusting spring decreases first and then increases along the axial direction; threaded holes matching with the threaded seats are provided on both sides of the adjusting slider.

[0018] In the above scheme, the adjusting spring and the adjusting slider are set as a detachable structure, so that the number of adjusting sliders and adjusting springs can be adjusted according to actual stacking requirements. This design allows the work site to be quickly converted without frequent replacement of tooling, thereby adapting to cylindrical materials of different quantities and specifications.

[0019] Preferably, the adjustment plate includes an adjustment plate body and an adjustment leg; the adjustment plate body includes a rotating portion and a bent plate portion; the adjustment leg is connected to the stacking frame; the rotating portion is connected to the adjustment leg; and the bent plate portion can be freely engaged with the adjustment slider.

[0020] In the above scheme, when the cylindrical material on the side is pressed on the rotating part, a torque is provided to the rotating part, so that the bent plate part generates a turning moment. Under the action of the turning moment, the bent plate part will exert an upward pressure on the adjusting slider, so that the adjusting slider and the bent plate part can remain stable, increase the friction, and prevent the two from sliding in the horizontal direction. When the stacking weight increases, the upward pressure and friction will increase accordingly, thereby maintaining the stability of the stacking structure; and the bent plate part can be freely clamped between the two adjusting sliders, so that the disassembly and assembly of the structure is more flexible, suitable for cylindrical materials of various quantities and specifications, and further improves practicality.

[0021] Preferably, the separation slider includes a limit plate, a separation rotating block, a contraction block and a contraction spring; the limit plate is slidably installed in the separation slide groove; the separation rotating block is rotatably installed on the limit plate, and a contraction groove is provided on the separation rotating block; the contraction block is slidably installed in the contraction groove; the contraction spring is connected between the contraction groove and the contraction block.

[0022] In the above scheme, by setting the separation slider as a rotatable and retractable structure, and under the action of the limit plate, the separation rotating block can only automatically rotate and retract when the cylindrical materials are collectively pulled up and lifted away after stacking and packaging, thereby ensuring that when the cylindrical materials are stacked, the overall stability of the stacking structure can be increased, the pressure of each layer on the lower layer can be reduced, and the cylindrical materials can be removed normally and smoothly from the stacking rack after packaging, and the separation rotating block will not cause jamming between the cylinder and the fixing mechanism.

[0023] Preferably, the connecting assembly comprises a connecting rod and a driving block; the connecting rod is connected to the adjusting slider on the upper side of the bent plate portion; and the driving block is connected to the lowermost separation slider.

[0024] In the above scheme, the driving block follows the process of the separation slider sliding down, so that the connecting rod slides under the pressure of the driving slider, thereby causing the connecting rod to drive the adjusting slider to slide. Since the adjusting slider on the upper side of the bent plate is the outermost one in contact with the cylindrical material, when the adjusting slider slides at this time, all the adjusting springs will be evenly stretched for a short distance to complete the pre-opening action between the adjusting sliders, thereby avoiding the cylindrical material from being unable to smoothly enter between the two adjusting sliders due to the large diameter difference between the maximum diameter specification material and the minimum diameter specification material produced, thereby ensuring that the cylindrical material at the bottom layer can accurately enter the gap between each two adjusting sliders.

[0025] Preferably, a sliding wheel is provided at the tail of the connecting rod; and the driving block comprises a downward pressing inclined surface and a tightening track.

[0026] In the above scheme, the downward pressing slope can press the connecting rod during the pressing process, thereby expanding the adjusting spring, and the expansion distance can be controlled by adjusting the length of the downward pressing slope, and the expansion distance is controlled to a smaller distance, thereby avoiding the expansion distance being too large and causing the two cylinders to fall into the gap between the two adjusting sliders, and the tightening track is a horizontal track, so that the sliding wheel is pressed down to separate from the retracting slope and enter the tightening track, and the tightening distance can be freely adjusted under the action of the elastic force of the adjusting spring, and the connecting rod can automatically realize the reset function under the action of the adjusting spring, thereby improving the degree of automation of the equipment.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. Compared with the existing cylindrical stacking device, the present invention can adapt to the packaging needs of cylindrical materials of various specifications and models by setting the position of the adjustment plate to an automatically adjustable structure, and setting the adjustment spring and the adjustment slider to a detachable structure, thereby reducing the number of tooling required in the production process. By adjusting the distance between the sliders, adaptive adjustment can be made under the pressure of the cylindrical material. On the one hand, it can adapt to cylindrical materials of different diameters, and on the other hand, it can make the cylindrical materials placed on the bottom layer of the stacking rack regular, thereby improving the stability of the overall stacking structure, not only facilitating the induction and arrangement of tooling, but also reducing production costs, so that the staff can complete the replacement and adjustment of the stacking rack in a short time, thereby reducing the time for replacing tooling and improving work efficiency.

[0029] 2. The present invention provides a separation slider, so that when each layer of cylindrical materials is stacked, the impact force of the cylindrical materials being lowered on the cylindrical materials that have been stacked in the lower layer can be reduced, and a certain supporting force can be provided for each layer of cylindrical materials, and each layer of cylindrical materials can be distinguished, thereby ensuring the stability of the overall stacking structure. At the same time, the separation slider is a rotatable and retractable structure that will not hinder subsequent packaging and transportation, further improving the forming effect of the cylindrical material packaging and stacking, and effectively reducing the problems of poor tightening effect of the strapping belt and collapse after packaging caused by the unformed stacking; this helps to improve product quality, reduce customer complaint rate, and enhance the market competitiveness of enterprises.

[0030] 3. The present invention inserts the bent plate portion of the adjustment plate between the adjustment sliders, which, on the one hand, achieves the adjustment of the overall stacking structure size to adapt to the stacking of different numbers of cylindrical materials; on the other hand, when the cylindrical materials on the side are pressed on the rotating portion of the adjustment plate, a torque is provided to the rotating portion, thereby causing the bent plate portion to generate a flipping torque. Under the action of the flipping torque, the bent plate portion applies an upward pressure to the adjustment slider, thereby allowing the adjustment slider and the bent plate portion to remain stable, increasing friction, and preventing the two from sliding in the horizontal direction. When the stacking weight increases, the upward pressure and friction will increase accordingly, thereby maintaining the stability of the stacking structure, thereby avoiding poor packaging effect due to the shapeless stacking, affecting subsequent storage and transportation.

DETAILED DESCRIPTION

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] See also Figures 1 to 9 The present invention provides a combined packaging and stacking equipment for cylindrical materials in a factory, and the technical solution is as follows:

[0044] As a specific embodiment of the present invention, refer to Figure 1A combined packaging and stacking equipment for cylindrical materials in a factory, comprising a transport mechanism 1 and a grabbing mechanism 2; further comprising a stacking frame 3, a fixing mechanism 4 and an adjusting mechanism 5; the stacking frame 3 is connected to the grabbing mechanism 2; the fixing mechanism 4 is connected to the stacking frame 3; the adjusting mechanism 5 comprises an adjusting hole 51 and an adjusting plate 52; the adjusting hole 51 is opened on the fixing mechanism 4; the adjusting plate 52 is connected to the fixing mechanism 4; the grabbing mechanism 2 grabs the cylindrical material to the stacking frame 3 and drives the cylindrical material Sliding downward, the fixing mechanism 4 on the stacking rack 3 receives the cylindrical material sliding downward and slowly moves it downward to the position of the adjusting mechanism 5. The adjusting hole 51 slides open under the downward pressure of the cylindrical material and then contracts and compresses the cylindrical material. The adjusting plate 52 is pressed by the pressure of the outermost cylindrical material to limit the adjusting hole 51. When the penultimate layer of cylindrical materials is stacked, the fixing mechanism 4 separates the penultimate layer of cylindrical materials from the bottom layer of cylindrical materials and provides a part of the upward supporting force for the cylindrical materials above the bottom layer.

[0045] As a specific embodiment of the present invention, refer to Figure 2 and Figure 3 The fixing mechanism 4 includes a fixing plate 41, a separation slot 42, a separation slider 43, a separation spring 44 and a connecting component 45; the separation slot 42 is opened on the inner wall of the fixing plate 41; a plurality of separation sliders 43 are slidably installed in the separation slot 42; the separation spring 44 is installed at intervals from the separation slider 43; the connecting component 45 is connected between the separation slider 43 and the adjusting mechanism 5. The separation slider 43 is installed on the side wall of the fixed plate 41, and the separation slider 43 is set to multiple pieces. Here, in order to ensure a good supporting effect, the number of the separation sliders 43 can be set to half of the total number of stacked layers plus one, so that the cylindrical materials in the lower half area can obtain lateral support force, so that the lower structure will not collapse; the separation slider 43 of each layer is at the same angle as the side wall of the fixed plate 41. When each layer of cylindrical materials is lowered, the outermost cylindrical materials will contact the side wall of the fixed plate 41 when they reach the bottom position. At this time, the separation slider 43 of the lowermost layer will contact the outermost cylindrical materials, so that the cylindrical materials can be clearly layered under the action of the separation slider 43 when stacking, and due to the action of the separation spring 44, the lowering of the cylindrical materials can be buffered to avoid impact on the cylindrical materials at the bottom layer and cause collapse, and each layer can obtain a part of the upward support force under the elastic force of the separation spring 44 when stacking, so that each layer of cylindrical materials can be well supported.

[0046] As a specific embodiment of the present invention, refer to Figure 3The fixed plate 41 includes a bottom plate 411 and a support plate 412; the bottom plate 411 is connected to the stacking frame 3; the support plate 412 is connected to the bottom plate 411, and the angle between the bottom plate 411 and the support plate 412 is 120 degrees. Since cylindrical materials are usually stacked into a hexagonal structure in order to ensure stability and reduce the space occupied during stacking, and the internal angle of the hexagonal structure formed is 120 degrees, the bottom plate 411 and the support plate 412 are fixed to a 120-degree structure, which can provide good support for the stacked cylindrical materials, so that the stacking is formed, so that the cylindrical materials in the outer circle can be tangentially contacted with the support plate 412, so that each cylindrical material in the outer circle can be supported, thereby ensuring the stability of the stacking structure.

[0047] As a specific embodiment of the present invention, refer to Figure 3 and Figure 4The adjusting hole 51 includes an adjusting slot 511, an adjusting slider 512 and an adjusting spring 513; the adjusting slot 511 is symmetrically arranged on both sides of the bottom plate 411; a plurality of adjusting sliders 512 are slidably installed in the adjusting slot 511; the adjusting spring 513 is installed at intervals with the adjusting slider 512. The adjusting hole 51 is set to a structure that can automatically adjust the size, so that cylindrical materials with different apertures can be placed. Every two adjusting sliders 512 can adjust the distance between the two adjusting sliders 512 by adjusting the elastic force of the spring 513, so that after the cylindrical material is placed between the two adjusting sliders 512, the cylindrical material can be clamped by adjusting the elastic force of the spring 513, so as to ensure that the cylindrical material will not shake, and increase the stability of the bottom stacking, ensure that the subsequent stacking can be formed, and can adapt to cylindrical materials with different diameters. The upper part of the adjusting slider 512 is symmetrically provided with fitting arc surfaces 5121, and the top ends of the fitting arc surfaces 5121 on the left and right sides of the upper part are tangent to each other, thereby ensuring that the top end is a pointed structure, thereby ensuring that each cylindrical material can be in tangential contact, thereby ensuring the compactness of the overall stacking structure, thereby improving the packaging effect; the fitting arc surface 5121 is made of rubber material, and when clamping the cylindrical material, the center of the arc line of the cross section of the fitting arc surface 5121 is eccentrically set compared to the center of the cross section of the cylindrical material. The rubber-made fitting arc surface 5121 can further improve the stability of the bottom cylindrical material after being clamped and fixed, and the rubber material can deform to a certain extent under the clamping force to maintain fit with the cylindrical material. The rubber material can increase the friction without wearing the surface of the cylindrical material, thereby preventing the cylindrical material from radially sliding under the clamping force. Since the radius of curvature of the fitting arc surface 5121 is greater than the radius of the cylindrical material, in order to ensure that the fitting arc surface 5121 can increase the contact area with the cylinder, the center of the arc line of the cross section of the fitting arc surface 5121 is eccentrically set compared to the center of the cross section of the cylindrical material when clamping the cylindrical material, so that each cylindrical material in the bottom layer can be better fixed and the stability is improved. Threaded seats 5131 are provided at both ends of the adjusting spring 513, and the elastic modulus of the adjusting spring 513 decreases first and then increases along the axial direction (i.e., the elastic modulus at both ends is large and the elastic modulus in the middle is small), so that after the cylindrical material is pressed downward to open the two adjusting sliders 512, the adjusting spring 513's ability to resist deformation increases, so that the cylindrical material is pressed down to be tangent to the bottom plate 411 and is subjected to the maximum clamping force; threaded holes 5122 that match the threaded seats 5131 are provided on both sides of the adjusting slider 512. The adjusting spring 513 and the adjusting slider 512 are set as a detachable structure, so that the number of adjusting sliders 512 and adjusting springs 513 can be adjusted according to actual stacking requirements. This design allows the work site to be quickly converted without frequent tooling changes, thereby adapting to cylindrical materials of different quantities and specifications.

[0048] As a specific embodiment of the present invention, refer to Figure 7 The adjusting plate 52 comprises an adjusting plate body 521 and an adjusting leg 522; the adjusting plate body 521 comprises a rotating portion 5211 and a bent plate portion 5212; the adjusting leg 522 is connected to the stacking frame 3; the rotating portion 5211 is connected to the adjusting leg 522; the bent plate portion 5212 can be freely engaged with the adjusting slider 512. When the cylindrical material on the side is pressed on the rotating part 5211, a torque is provided to the rotating part 5211, so that the bent plate part 5212 generates a turning moment. Under the action of the turning moment, the bent plate part 5212 will exert an upward pressure on the adjusting slider 512, so that the adjusting slider 512 and the bent plate part 5212 can remain stable, increase the friction, and prevent the two from sliding in the horizontal direction. When the stacking weight increases, the upward pressure and friction will increase accordingly, thereby maintaining the stability of the stacking structure; and the bent plate part 5212 can be freely clamped between the two adjusting sliders 512, so that the disassembly and assembly of the structure is more flexible, suitable for cylindrical materials of various quantities and specifications, and further improves practicality.

[0049] As a specific embodiment of the present invention, refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The separation slider 43 includes a limit plate 431, a separation rotating block 432, a contraction block 433 and a contraction spring 434; the limit plate 431 is slidably installed in the separation slide groove 42; the separation rotating block 432 is rotatably installed on the limit plate 431, and a contraction groove 4321 is provided on the separation rotating block 432; the contraction block 433 is slidably installed in the contraction groove 4321, and the surface of the contraction block 433 in contact with the cylindrical material is set as an arc surface; the contraction spring 434 is connected between the contraction groove 4321 and the contraction block 433, and the elastic modulus of the contraction spring 434 is set small enough to enable the contraction block 433 to contract when it is squeezed with the cylindrical material without affecting the packaged cylindrical material. By setting the separation slider 43 as a rotatable and retractable structure, and under the action of the limit plate 431, the separation rotating block 432 can only automatically rotate and retract when the cylindrical materials are collectively pulled up and lifted away after stacking and packaging, thereby ensuring that when the cylindrical materials are stacked, the overall stability of the stacking structure can be increased, the pressure of each layer on the lower layer is reduced, and the cylindrical materials can be removed normally and smoothly from the stacking frame 3 after packaging, and the separation rotating block 432 will not cause jamming between the cylinder and the fixing mechanism 4.

[0050] As a specific embodiment of the present invention, refer to Figure 8 and Fig. 9The connecting assembly 45 includes a connecting rod 451 and a driving block 452; the connecting rod 451 is connected to the adjusting slider 512 on the upper side of the bent plate portion 5212; the driving block 452 is connected to the lowermost separation slider 43. The driving block 452 follows the separation slider 43 to slide down, so that the connecting rod 451 slides under the pressure of the driving slider, so that the connecting rod 451 drives the adjusting slider 512 to slide. Since the adjusting slider 512 on the upper side of the bent plate portion 5212 is the outermost one in contact with the cylindrical material, when the adjusting slider 512 slides, all the adjusting springs 513 will be evenly stretched for a short distance to complete the pre-opening action between the adjusting sliders 512. Moreover, since the adjusting springs 513 have been set to a structure with a large elastic modulus at both ends and a small elastic modulus in the middle, it is ensured that when multiple adjusting springs 513 are stretched, the middle part of the adjusting springs 513 is more easily stretched, so that the multiple adjusting springs 513 are stretched more evenly, avoiding the cylindrical material from being unable to smoothly enter between the two adjusting sliders 512 due to the large diameter difference between the maximum diameter specification material and the minimum diameter specification material produced, and ensuring that the cylindrical material at the bottom layer can accurately enter the gap between every two adjusting sliders 512. A sliding wheel 4511 is provided at the tail of the connecting rod 451; a pressing track 4521 is provided at the lower part of the driving block 452; a tightening track 4522 is provided above the pressing track 4521; the overall driving block 452 is configured as a detachable structure, and the angle between the pressing track 4521 and the tightening track 4522 can be adjusted according to the diameter of the cylindrical material, thereby ensuring that the specifications of the driving block 452 can be adjusted in time for cylindrical materials with excessively large diameter differences. The downward pressing slope can press the connecting rod 451 during the pressing process, thereby expanding the adjusting spring 513, and the expansion distance can be controlled by adjusting the length of the downward pressing slope, and the expansion distance can be controlled to a smaller distance, thereby avoiding the expansion distance being too large and causing the two cylinders to fall into the gap between the two adjusting sliders 512, and the tightening track 4522 is a horizontal track, so that the sliding wheel 4511 is pressed down to leave the contraction slope and enter the tightening track 4522, and the tightening distance can be freely adjusted under the elastic force of the adjusting spring 513, and the connecting rod 451 can automatically realize the reset function under the action of the adjusting spring 513, thereby improving the degree of automation of the equipment.

[0051] Working process: the grabbing mechanism 2 lowers the cylindrical material. When placing the bottom cylindrical material, the cylindrical material contacts the separation slider 43. The separation slider 43 moves downward under the pressure of the cylindrical material. The driving block 452 follows the separation slider 43 to slide and squeeze the connecting rod 451. The connecting rod 451 drives the adjusting slider 512 to slide for pre-opening. The cylindrical material continues to be pressed downward, so that a single cylindrical material enters between the two adjusting sliders 512. At this time, the adjusting slider 512 clamps the cylindrical material under the action of the adjusting spring 513, fixes the bottom cylindrical material, and continues to stack the cylindrical materials. At this time, the adjusting plate 52, the separation slider 43 and the fixed plate 41 support the upper cylindrical material.

[0052] Specifically, firstly, according to the number and diameter specifications of the cylindrical materials to be stacked, the number of separation sliders 43 on the fixing mechanism 4 and the adjusting sliders 512 on the adjusting mechanism 5 are disassembled and adjusted, and at the same time, the bent plate portion 5212 of the adjusting plate 52 is snapped to the bottom of the adjusting slider 512; the transport mechanism 1 transports the cylindrical material to the bottom of the grabbing mechanism 2, the grabbing mechanism 2 grabs the cylindrical material to the stacking frame 3 position, and the grabbing mechanism 2 lowers the cylindrical material. When placing the bottom layer of cylindrical materials, during the downward movement of the cylindrical materials, the outermost cylindrical materials generate downward pressure on the separation slider 43, and at this time, the separation spring 44 is stretched, and the separation slider 43 slides down to drive the driving block 452 slides down, and the downward track 4521 presses down the sliding wheel 4511 at the tail of the connecting rod 451, so that the adjusting slider 512 slides under the thrust of the connecting rod 451, and the multiple adjusting springs 513 are evenly stretched, so that the multiple adjusting sliders 512 complete the pre-opening action, and the cylindrical material continues to be pressed down, so that a single cylindrical material enters between the two adjusting sliders 512, and is squeezed between the fitting arc surface 5121 and the cylindrical material, so that the single cylindrical material completely opens the two adjusting sliders 512, and the cylindrical material is clamped and fixed by the fitting arc surface 5121 and the elastic force of the adjusting spring 513. At this time, the sliding wheel 4511 enters the tightening Horizontal sliding is performed in the track 4522 to ensure that the tightening process is not affected; the cylindrical materials are continuously stacked on the upper layer, and when the cylindrical materials on the side are pressed on the rotating part 5211, a torque is provided to the rotating part 5211, so that the bent plate part 5212 generates a turning moment. Under the action of the turning moment, the bent plate part 5212 will exert an upward pressure on the adjusting slider 512, so that the adjusting slider 512 and the bent plate part 5212 can both remain stable, increase the friction force, and prevent the two from sliding in the horizontal direction. When the stacking weight increases, the upward pressure and friction force will increase accordingly, thereby maintaining the stability of the stacking structure; and the cylindrical materials stacked on each layer The cylindrical materials will be separated under the action of multiple separation sliders 43, so that each layer will not be stacked without forming, and the separation slider 43 stretches the separation spring 44 in the process of following the cylindrical materials to slide down, so as to reduce the impact of the upper stacking on the lower structure, and ensure the stability of the overall stacking structure; after the overall stacking is completed, the packing belt is used for packaging, and when the cylindrical materials need to be transported away after packaging, the cylindrical materials are lifted upwards, and at this time, the separation rotating block 432 automatically rotates on the limiting plate 431, and the shrinking block 433 is squeezed and contracted with the cylindrical materials into the separation rotating block 432, thereby separating from the cylindrical materials that have been packaged, so that the cylindrical materials that have been packaged can be smoothly transported away.
