Description

Technical Field

[0001] The present application relates to the technical field of net-wrapping machines, and in particular to a clamping mechanism for a net-renewing device of a net-wrapping machine. Background Art

[0002] In today's rapidly developing economy, people's demand for material goods is constantly increasing, and their expectations for products are becoming increasingly higher. For example, the fruit market is growing, and the transportation of fruit requires consideration for protecting bruise-prone fruits. Therefore, efficient, convenient, and high-quality fruit packaging equipment has become an effective competitive advantage in the fruit market. Currently, the main fruit packaging equipment on the market is pillow-type and heat-shrinkable packaging. There is no fruit packaging equipment specifically designed for EPE netting, making it impossible to fully utilize this economical and practical anti-scratch material to provide comprehensive protection for fruit. EPE netting is a very common packaging material used on the market for fruits such as apples and pears. It has a certain degree of shrinkage. When the fruit is inserted into the cylindrical EPE netting, its ends automatically shrink, providing comprehensive protection for the fruit.

[0003] When renewing or adding mesh to the mesh machine, some equipment requires manual mesh addition, and the operator needs to manually place the mesh into the mesh machine, which is relatively dangerous. Equipment that uses clamps often uses complex clamps to clamp the mesh and add mesh. The cost of this type of clamp is relatively high and the operation is not particularly convenient. Utility Model Content

[0004] In order to overcome the disadvantage of high cost of the clamps used for the net-laying machine in the prior art, the present application provides a clamping mechanism for the net-laying machine's net-laying machine, which can facilitate the clamping of the net and the addition of the net.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a clamping mechanism for a net-laying machine and a net-renewing device, comprising a frame and a core on the outside of which a net can be laid, the ends of the core being divided into a net-in end and a net-out end, the core having a guide section connected to the net-out end, the cross-sectional area of ​​the guide section decreasing from the net-out end to the net-in end, and the frame being provided with a floating clamping guide assembly for clamping the core and aligning the core with the center of the frame.

[0006] After adopting the above technical scheme, the present application has the following advantages: by arranging the mesh sleeve outside the movement in the sleeve mechanism, the end of the mesh sleeve is fixed on the movement, and then the movement and the mesh sleeve are aligned with the center of the frame through the floating clamping guide assembly, the relative positions of the mesh sleeve and the frame are fixed, and then the frame is installed at the entrance of the mesh machine to complete the meshing. Due to the variable cross-sectional area design of the movement, the floating component of the floating clamping guide assembly naturally slides to the small end of the guide section of the movement when clamping the movement, so that the cooperation between the movement and the floating clamping guide assembly can better clamp the mesh sleeve, and the floating clamping guide assembly can be freely adjusted when encountering mesh sleeves of different thicknesses when entering the net, and can provide a certain degree of freedom for the movement, so that the movement is more accurate when docking with the mesh machine. Since it is more convenient to arrange the mesh sleeve on the movement, it is more convenient and faster than the existing technology.

[0007] Furthermore, the core is provided with a roller group arranged at vertical intervals and used to guide the net sleeve, and the guide section is arranged between the lowermost roller group and the net outlet end.

[0008] By adopting the above-mentioned technical solution, through the roller group for guiding the mesh sleeve provided on the movement, when the mesh sleeve is installed, the roller group can guide the mesh sleeve to slide smoothly toward the movement, reducing the resistance and jamming during the installation process, so that the mesh sleeve can be quickly and accurately installed on the movement, greatly improving the efficiency of the mesh sleeve installation. When the movement enters the floating clamping guide assembly, it will abut against the roller group and the small end of the guide section. Therefore, the vertical limitation of the movement can be achieved through the roller group and the floating clamping guide assembly.

[0009] Furthermore, the guide section is a conical structure.

[0010] By adopting the above-mentioned technical solution, the guide section is set to be conical, so that after the movement is installed into the floating clamping guide assembly, the movement will be automatically pushed to the small diameter position of the guide section, so that the movement can automatically complete the positioning with the frame without being subject to other external forces.

[0011] Furthermore, the outlet end is a cylindrical section.

[0012] By adopting the above-mentioned technical solution, the net outlet end is set as a cylindrical section to increase the friction between the net sleeve and the movement, thereby preventing the net sleeve from slipping out when the movement is installed in the floating clamping guide assembly.

[0013] Furthermore, the diameter of the mesh outlet end of the core is larger than the diameter of the mesh sleeve when not subjected to external force.

[0014] By adopting the above-mentioned technical solution, when the mesh sleeve is put on the movement, due to the larger diameter of the mesh outlet end, the mesh sleeve will shrink to a certain extent after passing through the mesh outlet end, thereby increasing the friction between the mesh sleeve and the movement. This friction can effectively prevent the mesh sleeve from easily slipping out during subsequent operations, ensuring that the mesh sleeve is firmly fixed on the movement and improving the stability and reliability of the mesh renewal process.

[0015] Furthermore, the floating clamping guide assembly includes at least two rollers arranged opposite to each other, and the rollers are connected to the frame via elastic members, and the elastic members act on the rollers to cause them to have a tendency to move radially inwards.

[0016] By adopting the above-mentioned technical solution, the elastic part enables the roller to automatically adjust the clamping force according to the size of the mesh and the movement. When the thickness of the mesh is different or the size of the movement changes to a certain extent, the roller can flexibly adapt under the action of the elastic part, ensuring that the movement and the mesh can always be tightly clamped, thereby improving the versatility and adaptability of the device. The connection method of the elastic part can absorb part of the external force impact and reduce the risk of damage to the device and the mesh. The roller is used for clamping, and it can roll during the process of conveying the mesh without causing friction to the mesh and damaging the mesh surface. In addition, this design facilitates the disassembly and assembly of the movement and improves the speed of mesh renewal.

[0017] Furthermore, the roller is mounted on a roller shaft frame, and the roller shaft frame is slidably connected to the frame through two guide rods. An elastic member is provided on the outer side of the guide rod, one end of which is connected to the frame and the other end is connected to the roller shaft frame.

[0018] Using the above-mentioned technical solution, the roller is installed on the roller shaft frame, and the roller shaft frame is slidably connected to the frame through two guide rods. This structure provides a more stable support for the roller. During the clamping and guiding process, the roller will not shake or deviate, ensuring accurate clamping and guiding of the movement and mesh sleeve. The sliding connection between the guide rod and the frame allows the roller shaft frame to move freely within a certain range, so that it can be precisely adjusted according to different mesh sleeves and movement sizes.

[0019] Furthermore, the floating clamping guide assembly includes four rollers, which are respectively arranged in the front-to-back direction and the left-to-right direction.

[0020] By adopting the above-mentioned technical solution, four rollers clamp the movement from the front, back, left and right directions, which can achieve all-round fixation and guidance. No matter which direction the movement has a slight deviation, it can be adjusted back to the correct position in time by the rollers to ensure that the relative position of the mesh sleeve and the movement is always accurate, thereby improving the accuracy and stability of the mesh. The rollers in the front, back and left and right directions cooperate with each other to make the clamping force more evenly distributed around the movement. This uniform clamping force can prevent the movement from being damaged due to excessive force in some parts of the body, and at the same time ensure that the mesh sleeve can fit tightly on the movement in all directions, thereby improving the fixing effect of the mesh sleeve.

[0021] Furthermore, the floating clamping guide assembly is a structure composed of at least two groups of relatively arranged elastic members and annular clamps. When the mesh sleeve is conveyed, the clamp is at the small end of the guide section of the movement and there is a certain gap between it and the mesh sleeve on the movement.

[0022] With the aforementioned technical solution, the presence of the elastic member allows the annular clamp to be adjusted to a certain degree of expansion and contraction according to the size of the movement. When facing movements of different diameters, the elastic member can be compressed or stretched, allowing the clamp to tightly clamp the small end of the movement's guide section, improving the versatility of the device and adapting to movements of different specifications. The combined structure of the annular clamp and the elastic member is relatively simple and occupies less space, making it more suitable for installation environments with limited space. When the clamp is conveying the mesh, the movement and the clamp of the mesh machine are located at the small end of the movement's guide section, with a certain gap, to avoid wear on the mesh.

[0023] Furthermore, a bracket connected to the frame is provided on the upper side of the movement, and the bracket is used to guide the net sleeve clamped between the floating clamping guide assembly and the movement.

[0024] By adopting the above-mentioned technical solution, the bracket can provide a clear guide path for the mesh sleeve, so that the mesh sleeve can accurately enter the predetermined position during the process of being clamped by the floating clamping guide assembly, avoiding the mesh sleeve from being offset, entangled or misplaced during the entry process, ensuring that the mesh sleeve can be smoothly wrapped on the movement, and improving the accuracy and efficiency of the mesh renewal.

[0034] The following specific embodiments are used to describe the technical solution of the present application in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0035] Example 1:

[0036] like Figures 1 to 5As shown, the present application provides a clamping mechanism for a net-laying machine and a net-renewing device, comprising a frame 2 and a core 3 on the outside of which a net sleeve 1 can be sleeved, the end 32 of the core 3 being divided into a net-in end 321 and a net-out end 322, the core 3 being provided with a guide section connected to the net-out end 322, the cross-sectional area of ​​the guide section decreasing from the net-out end 322 to the net-in end 321, the frame 2 being provided with a floating clamping guide assembly 4 for clamping the core 3 and aligning the core 3 with the center of the frame 2.

[0037] After adopting the above technical scheme, the present application has the following advantages: the mesh sleeve 1 is arranged outside the movement 3 in the sleeve mechanism, so that the end of the mesh sleeve 1 is fixed on the movement 3, and then the movement 3 and the mesh sleeve 1 are aligned with the center of the frame 2 through the floating clamping guide assembly 4, and the relative positions of the mesh sleeve 1 and the frame 2 are fixed, and then the frame 2 is installed at the entrance of the mesh machine to complete the mesh renewal. Due to the variable cross-sectional area design of the movement 3, the floating component of the floating clamping guide assembly 4 naturally slides to the small end of the guide section of the movement 3 when clamping the movement 3, so that the cooperation between the movement 3 and the floating clamping guide assembly 4 can better clamp the mesh sleeve 1, and the floating clamping guide assembly 4 can be freely adjusted when encountering mesh sleeves 1 of different thicknesses when entering the net, and can provide a certain degree of freedom for the movement 3, so that the movement 3 is more accurate when docking with the mesh machine. Since it is more convenient to set the mesh sleeve 1 on the movement 3, it is more convenient and faster than the existing technology.

[0038] Furthermore, the core 3 is provided with roller groups 34 arranged at vertical intervals and used to guide the net sleeve 1, and the guide section is provided between the lowermost roller group 34 and the net outlet end 322.

[0039] By adopting the above-mentioned technical solution, a roller group 34 for guiding the net sleeve 1 is provided on the movement 3. When the net sleeve 1 is installed, the roller group 34 can guide the net sleeve 1 to slide smoothly toward the movement 3, reducing the resistance and jamming during the installation process, so that the net sleeve 1 can be quickly and accurately installed on the movement 3, greatly improving the efficiency of the installation of the net sleeve 1. When the movement 3 enters the floating clamping guide assembly 4, it will abut against the roller group 34 and the small end of the guide section. Therefore, the vertical limitation of the movement 3 can be achieved by the roller group 34 and the floating clamping guide assembly 4.

[0040] Furthermore, the guide section is a conical structure.

[0041] By adopting the above-mentioned technical solution, the guide section is set to be conical, so that after the movement 3 is installed into the floating clamping guide assembly 4, the movement 3 will be automatically pushed to the small diameter position of the guide section, so that the movement 3 can automatically complete the positioning with the frame 2 without being subject to other external forces.

[0042] Furthermore, the net outlet end 322 is a cylindrical segment.

[0043] By adopting the above-mentioned technical solution, the net outlet end 322 is set as a cylindrical section to increase the friction between the net sleeve 1 and the movement 3, thereby preventing the net sleeve 1 from slipping out when the movement 3 is installed in the floating clamping guide assembly 4.

[0044] Furthermore, the diameter of the mesh outlet end 322 of the core 3 is larger than the diameter of the mesh sleeve 1 when not subjected to external force.

[0045] By adopting the above-mentioned technical solution, when the mesh sleeve 1 is inserted into the movement 3, due to the large diameter of the mesh outlet end 322, the mesh sleeve 1 will shrink to a certain extent after passing through the mesh outlet end 322, thereby increasing the friction between the mesh sleeve 1 and the movement 3. This friction can effectively prevent the mesh sleeve 1 from easily slipping out during subsequent operations, ensuring that the mesh sleeve 1 is firmly fixed on the movement 3, and improving the stability and reliability of the mesh renewal process.

[0046] Furthermore, the floating clamping guide assembly 4 includes at least two rollers 41 arranged opposite to each other. The rollers 41 are connected to the frame 2 via elastic members 42. The elastic members 42 act on the rollers 41 to cause them to have a tendency to move radially inward.

[0047] By adopting the above-mentioned technical solution, the elastic member 42 enables the roller 41 to automatically adjust the clamping force according to the size of the mesh sleeve 1 and the movement 3. When the thickness of the mesh sleeve 1 is different or the size of the movement 3 changes to a certain extent, the roller 41 can flexibly adapt under the action of the elastic member 42, ensuring that the movement 3 and the mesh sleeve 1 can always be tightly clamped, thereby improving the versatility and adaptability of the device. The connection method of the elastic member 42 can absorb part of the external force impact and reduce the risk of damage to the device and the mesh sleeve 1. The roller 41 is used for clamping, and it can roll during the process of conveying the mesh sleeve 1 without causing friction and damage to the mesh surface of the mesh sleeve 1. In addition, this design facilitates the disassembly and assembly of the movement 3 and improves the speed of mesh renewal.

[0048] Furthermore, the roller 41 is mounted on a roller frame 44 , and the roller frame 44 is slidably connected to the frame 2 via two guide rods 43 . An elastic member 42 is provided on the outside of the guide rod 43 , one end of which is connected to the frame 2 and the other end is connected to the roller frame 44 .

[0049] Using the above-mentioned technical solution, the roller 41 is installed on the roller frame 44, and the roller frame 44 is slidably connected to the frame 2 through two guide rods 43. This structure provides a more stable support for the roller 41. During the clamping and guiding process, the roller 41 will not shake or deviate, ensuring accurate clamping and guiding of the movement 3 and the mesh sleeve 1. The sliding connection between the guide rod 43 and the frame 2 allows the roller frame 44 to move freely within a certain range, so that it can be precisely adjusted according to different sizes of the mesh sleeve 1 and the movement 3.

[0050] Furthermore, the floating clamping guide assembly 4 includes four rollers 41 , which are respectively arranged in the front-to-back direction and the left-to-right direction.

[0051] By adopting the above-mentioned technical solution, four rollers 41 clamp the movement 3 from the front, back, left and right directions, which can achieve all-round fixation and guidance. No matter which direction the movement 3 has a slight deviation, it can be adjusted back to the correct position in time by the rollers 41, ensuring that the relative position of the mesh sleeve 1 and the movement 3 is always accurate, improving the accuracy and stability of the mesh renewal, and the rollers 41 in the front, back and left and right directions cooperate with each other to make the clamping force more evenly distributed around the movement 3. This uniform clamping force can prevent the movement 3 from being damaged due to excessive force in some parts of the body, and at the same time ensure that the mesh sleeve 1 can fit tightly on the movement 3 in all directions, thereby improving the fixing effect of the mesh sleeve 1.

[0052] Furthermore, a bracket 21 connected to the frame 2 is provided on the upper side of the movement 3 , and the bracket 21 is used to guide the net sleeve 1 clamped between the floating clamping guide assembly 4 and the movement 3 .

[0053] By adopting the above-mentioned technical solution, the bracket 21 can provide a clear guide path for the mesh sleeve 1, so that the mesh sleeve 1 can accurately enter the predetermined position during the process of being clamped by the floating clamping guide assembly 4, avoiding the mesh sleeve 1 from being offset, entangled or misplaced during the entry process, ensuring that the mesh sleeve 1 can be smoothly wrapped on the core 3, and improving the accuracy and efficiency of the mesh renewal.

[0054] Example 2: The floating clamping guide assembly 4 is a structure composed of at least two groups of relatively arranged elastic members 42 and annular clamps. When the mesh sleeve 1 is conveyed, the clamp is at the small end 33 of the guide section of the movement 3, and there is a certain gap between it and the mesh sleeve 1 on the movement 3.

[0055] With the aforementioned technical solution, the presence of the elastic member 42 enables the annular clamp to be adjusted to a certain extent according to the size of the movement 3. When facing movements 3 of different diameters, the elastic member 42 can be compressed or stretched, so that the clamp can tightly clamp the small end 33 of the guide section of the movement 3, thereby improving the versatility of the device and adapting to movements 3 of different specifications. In addition, the combined structure of the annular clamp and the elastic member 42 is relatively simple and occupies less space, making it more suitable for installation environments with limited space. When the clamp is conveying the mesh sleeve 1, the movement 3 and the clamp of the mesh sleeve machine are located at the small end 33 of the guide section of the movement 3, and there is a certain gap, which avoids wear on the mesh sleeve 1.

[0056] Specifically, the annular clamp is an arc-shaped ring, and its concave surface faces inward. The elastic member 42 is fixed to the convex surface of the annular clamp and is installed at the small end of the guide section. The contact surface between the annular clamp and the movement is smooth with an inwardly convex arc to reduce the friction between the mesh sleeve on the movement; multiple annular clamps can form a full circle when they abut against each other; the upper edge diameter of the arc-shaped ring is larger than the diameter of the lower edge, so that the movement can enter smoothly when inserted into the annular clamp.

[0057] In addition to the above-mentioned preferred embodiments, the present application also has other implementation methods. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present application.
