Description

Technical Field

[0001] The present application relates to the technical field of mesh wrapping machines, and in particular to a device for renewing mesh in mesh wrapping machines. 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] The existing technology usually uses manual network addition, which is a cumbersome process and requires people to perceive the adding points, which has subjective inconsistencies. The location of the network adding port is sometimes high from the ground, making manual network addition difficult to implement. Utility Model Content

[0004] In order to overcome the shortcomings of poor centering of manual network renewal in the prior art, the present application provides a device for network renewal of a network machine, which can achieve automatic network renewal and improve the centering effect.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a device for renewing the net of a net-making machine, comprising a base, a frame and a first movement, the base being provided with a net inlet, a second movement installed on the net-making machine being provided below the net inlet, the first movement being movably provided above the second movement, a first positioning portion being provided on the first movement, a second positioning portion being provided on the second movement, the first positioning portion and the second positioning portion cooperating to align the net on the first movement with the second movement, the frame being movably connected to the base, the frame being provided with a clamping guide assembly clamped on the outside of the first movement, the clamping guide assembly and the first movement clamping the net.

[0006] The netting process of the present device is as follows: first, the net is fully placed on the outside of the first movement so that the net is aligned with the axis of the first movement, then the clamping guide assembly on the frame clamps the first movement therein, and then the frame is connected to the base so that the first positioning portion of the first movement and the second positioning portion of the second movement are aligned and matched together so that the net can be aligned with the second movement, thereby completing the rapid netting. After adopting the above technical solution, the present application has the following advantages: the relative position of the first movement and the frame is determined by the clamping guide assembly on the frame, then the frame is connected to the base so that the first movement can be aligned with the second movement, and then the first positioning portion and the second positioning portion are matched so that the net placed on the first movement can be accurately aligned with the second movement, making the netting more convenient and quick. Since it is more convenient and easy to place the net on the outside of the first movement, the overall netting work is faster. It is also possible to prepare multiple sets of first movements and frames, and put the net on the first movement in advance and install it in the clamping guide assembly of the frame, making the netting work more convenient and direct.

[0007] Furthermore, the first positioning portion or the second positioning portion is a guide column, and the other is a guide hole adapted to the guide column.

[0008] By adopting the above-mentioned technical solution, the cooperation between the guide column and the guide hole can provide precise guidance for the alignment of the first movement and the second movement. During the meshing process, it ensures that the axes of the two movements can overlap quickly and accurately, greatly improving the centering. This high-precision alignment enables the mesh sleeve to transition more accurately from the first movement to the second movement, reducing the mesh sleeve from being torn due to poor centering.

[0009] Furthermore, the clamping guide assembly includes a roller, the rolling direction of the roller is the same as the direction of the conveying sleeve, the roller and the frame are connected by an elastic member, the first movement is provided with an end portion and a middle portion, and the cross-sectional area of ​​the first movement decreases from the end portion to the middle portion.

[0010] With the aforementioned technical solution, since the cross-sectional area of ​​the first movement decreases from the end to the middle part, when the first movement is installed between the rollers, it will roll to the middle part of the first movement due to the action of the elastic member, so that the first movement can be clamped in the frame without the action of external force, making the subsequent alignment of the first movement more convenient and quick.

[0011] Furthermore, the first movement is tapered from the end close to the second movement to the middle part, and a roller group for guiding the net is provided near the other end of the first movement, and the same roller group is also provided near the middle part.

[0012] By adopting the above-mentioned technical solution, since the end and the middle part of the first movement away from the first positioning part are roller groups, the first movement can be smoother when the mesh is installed, and the efficiency of the mesh is improved. The setting of the roller group makes the first movement more flexible when cooperating with other components. Whether in the process of renewing the mesh or in other stages of the equipment operation, the roller group can be fine-tuned according to actual conditions to adapt to meshes of different sizes and materials, thereby improving the adaptability and versatility of the equipment.

[0013] Furthermore, at least two vertically extending slide rails are provided on the base relative to the network inlet, and sliding parts adapted to the slide rails are provided on the outside of the frame to align the first movement clamped in the frame with the second movement.

[0014] By adopting the above-mentioned technical solution, the slide rail provides stable support and guidance for the movement of the frame, preventing the frame from shaking or shifting during movement, and helping to align the first movement with the second movement, increasing the centering of the network. Through the cooperation of the slide rail and the sliding part, the operator can easily adjust the height of the frame, making the cooperation between the first movement and the second movement more flexible and conducive to precise cooperation.

[0015] Furthermore, the sliding member includes a support rod, one end of which is connected to the frame, and the other end of which is provided with a pulley adapted to the slide rail.

[0016] Using the above-mentioned technical solution, one end of the support rod is connected to the frame, providing a stable connection structure between the frame and the pulley, which can support the frame without shaking or tilting. The pulley adapted to the slide rail is arranged at the other end and can cooperate closely with the slide rail to ensure smooth sliding.

[0017] Furthermore, the width of the slideway of the slide rail gradually decreases from a direction away from the base to a direction close to the base.

[0018] With the aforementioned technical solution, when the frame moves downward along the slide rail, the sliding member will be guided to a more precise position due to the gradual reduction in the width of the slide rail, so that the first movement clamped in the frame can be more accurately aligned with the second movement. The narrower bottom of the slide rail can play a certain limiting role to prevent the sliding member from accidentally derailing during operation.

[0019] Furthermore, a bracket for guiding the net is provided on the upper side of the first movement.

[0020] By adopting the above-mentioned technical solution, the bracket can provide a clear guiding path for the net, so that the net can accurately enter from the top of the first movement to the outside of the first movement. During the net renewal process, this helps to avoid the net from being offset, entangled or misplaced, ensuring that the net can be smoothly placed on the first movement, thereby improving the accuracy and efficiency of net renewal.

[0021] Furthermore, the base is provided with symmetrically arranged clamping rollers for clamping the net outside the first movement. The clamping rollers are connected to a rotating driver so that after the clamping rollers and the first movement clamp the net, the clamping rollers are rotated to transport the net to the net inlet.

[0022] By adopting the above-mentioned technical solution, the clamping roller can tightly clamp the mesh on the outside of the first movement, and under the action of the rotating drive, the mesh can be stably transported to the mesh inlet. For meshes of different materials, the clamping roller can adapt to their characteristics by adjusting the clamping force and conveying speed. For example, for thinner or softer meshes, the clamping force and conveying speed can be appropriately reduced to prevent the mesh from being damaged; for thicker or harder meshes, the clamping force can be increased and the conveying speed can be increased to ensure that the mesh can be conveyed smoothly.

[0023] Furthermore, a rotation counter is provided inside the rotation driver.

[0024] By adopting the above-mentioned technical solution, a rotation counter is set inside the rotary driver, so that the rotary driver can accurately count the length of the net when working, so that the operator can be reminded to renew the net in time through the reminder device. It can also be combined with the control system. The data of the rotation counter can be used to automatically adjust the operating parameters of the equipment. For example, when it is detected that the net sleeve conveying length is too long or too short, the rotation speed of the rotary driver or the clamping force of the clamping roller can be automatically adjusted to achieve the best net sleeve conveying effect.

[0037] 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.

[0038] like Figures 1 to 7 As shown, the present application provides a device for renewing the net of a net-making machine, comprising a base 1, a frame 2 and a first movement 3, the base 1 being provided with a net inlet 11, a second movement 4 installed on the net-making machine being provided below the net inlet 11, the first movement 3 being movably provided above the second movement 4, a first positioning portion 31 being provided on the first movement 3, a second positioning portion 41 being provided on the second movement 4, the first positioning portion 31 and the second positioning portion 41 cooperating to align the net sleeve 7 on the first movement 3 with the second movement 4, the frame 2 being movably connected to the base 1, the frame 2 being provided with a clamping guide assembly 5 clamped on the outside of the first movement 3, the clamping guide assembly 5 and the first movement 3 clamping the net.

[0039] The re-netting process of this device is as follows: first, the net is fully sleeved on the outside of the first movement 3, so that the net sleeve 7 is aligned with the axis of the first movement 3, and then the clamping guide assembly 5 on the frame 2 clamps the first movement 3 therein, and then the frame 2 is connected to the base 1, so that the first positioning part 31 of the first movement 3 and the second positioning part 41 of the second movement 4 are aligned and matched together, so that the net sleeve 7 can be aligned with the second movement 4, thereby completing the rapid re-netting. After adopting the above technical solution, the present application has the following advantages: the relative position of the first movement 3 and the frame 2 is determined by the clamping guide assembly 5 on the frame 2, and then the frame 2 is connected to the base 1 so that the first movement 3 can be aligned with the second movement 4, and then the first positioning part 31 and the second positioning part 41 are matched to make the mesh sleeve 7 mounted on the first movement 3 can be accurately aligned with the second movement 4, making the re-netting more convenient and quick. Since it is more convenient and easy to mount the mesh sleeve 7 on the outside of the first movement 3, the overall re-netting work is faster. It is also possible to prepare multiple sets of first movements 3 and frames 2, and mount the mesh sleeve 7 on the first movement 3 in advance and install it in the clamping guide assembly 5 of the frame 2, making the re-netting work more convenient and direct.

[0040] Preferably, the center of the end of the mesh sleeve 7 coincides with the axis of the first movement 3, the axis of the first movement 3 coincides with the center of the frame 2, the frame 2 is installed in the center of the base 1, and the second movement 4 is located in the center of the base 1. After the first movement 3 and the second movement 4 are matched, the two axes coincide, so that the center of the mesh sleeve 7 coincides with the circumference of the second movement 4.

[0041] Among them, the mesh inlet 11 of the base 1 is at the center of the base 1; the mesh inlet 11 is the mesh inlet 11 of the mesh machine, and the second movement 4 is one of the conveying devices for conveying the mesh 7 into the mesh machine; the first movement 3 is movably arranged above the second movement 4, which means that the first movement 3 and the second movement 4 are separate structures; the first movement 3 and the second movement 4 can both be identified as axially symmetrical objects, so both have a straight line as their respective axes; the frame 2 is movably connected to the base 1, which means that the frame 2 and the base 1 can be separated.

[0042] Furthermore, the first positioning portion 31 or the second positioning portion 41 is a guide post, and the other is a guide hole adapted to the guide post.

[0043] By adopting the above-mentioned technical solution, the cooperation between the guide column and the guide hole can provide precise guidance for the alignment of the first movement 3 and the second movement 4. During the meshing process, it ensures that the axes of the two movements can be quickly and accurately overlapped, which greatly improves the centering. This high-precision alignment enables the mesh sleeve 7 to transition from the first movement 3 to the second movement 4 more accurately, reducing the mesh sleeve 7 from being torn due to poor centering.

[0044] It is understandable that the guide post and the guide hole can also be designed to be tapered, so that the cooperation between the guide post and the guide hole is more convenient and quick.

[0045] Furthermore, the clamping guide assembly 5 includes a roller 51, the rolling direction of the roller 51 is the same as the direction of the conveying sleeve, the roller 51 and the frame 2 are connected by an elastic member 52, the first movement 3 is provided with an end portion 32 and a middle portion 33, and the cross-sectional area of ​​the first movement 3 decreases from the end portion 32 to the middle portion 33.

[0046] With the aforementioned technical solution, since the cross-sectional area of ​​the first movement 3 decreases from the end portion 32 to the middle portion 33, when the first movement 3 is installed between the rollers 51, it will roll to the middle portion 33 of the first movement 3 due to the action of the elastic member 52, so that the first movement 3 can be clamped in the frame 2 without the action of external force, making the subsequent alignment of the first movement 3 more convenient and quick.

[0047] It is understandable that the clamping guide assembly 5 can also be a structure composed of an elastic member and an annular clamp, as well as other structures that can clamp the first movement 3 and align it in the center, all of which fall within the scope of protection of this application.

[0048] Furthermore, a cone is formed from the end 32 of the first movement 3 close to the second movement 4 to the middle part 33, and a roller group 34 for guiding the net is provided near the other end 32 of the first movement 3, and the same roller group 34 is also provided near the middle part 33.

[0049] By adopting the above-mentioned technical solution, since the end 32 and the middle part 33 of the first movement 3 away from the first positioning part 31 are the roller group 34, the first movement 3 is smoother when the mesh sleeve 7 is installed, and the efficiency of the mesh installation is improved. The setting of the roller group 34 makes the first movement 3 more flexible when cooperating with other components. Whether in the mesh renewal process or in other stages of equipment operation, the roller group 34 can be fine-tuned according to actual conditions to adapt to mesh sleeves 7 of different sizes and materials, thereby improving the adaptability and versatility of the equipment.

[0050] Furthermore, at least two vertically extending slide rails 12 are provided on the base 1 relative to the network inlet 11, and a sliding member adapted to the slide rails 12 is provided on the outside of the frame 2 to align the first movement 3 clamped in the frame 2 with the second movement 4.

[0051] By adopting the above-mentioned technical solution, the slide rail 12 provides stable support and guidance for the movement of the frame 2, preventing the frame 2 from shaking or offsetting during movement, and helping to align the first movement 3 with the second movement 4, thereby increasing the centering of the network. Through the cooperation of the slide rail 12 and the sliding part, the operator can easily adjust the height of the frame 2, making the cooperation between the first movement 3 and the second movement 4 more flexible and conducive to precise cooperation.

[0052] Preferably, the slide rail 12 is symmetrically arranged relative to the network access port 11 .

[0053] Furthermore, the sliding member includes a support rod 21 , one end of which is connected to the frame 2 , and the other end of which is provided with a pulley 22 adapted to the slide rail 12 .

[0054] Using the above-mentioned technical solution, one end of the support rod 21 is connected to the frame 2, providing a stable connection structure between the frame 2 and the pulley 22, which can support the frame 2 without shaking or tilting. The pulley 22 adapted to the slide rail 12 is arranged at the other end and can cooperate closely with the slide rail 12 to ensure smooth sliding.

[0055] Furthermore, the width of the slideway of the slide rail 12 gradually decreases from being away from the base 1 to being close to the base 1 .

[0056] By adopting the above-mentioned technical solution, when the frame 2 moves downward along the slide rail 12, the sliding part will be guided to a more precise position due to the gradual reduction of the slide width, so that the first movement 3 clamped in the frame 2 can be more accurately aligned with the second movement 4. The narrower bottom of the slide can play a certain limiting role to prevent the sliding part from accidentally derailing during operation.

[0057] Furthermore, a bracket 23 for guiding the net is provided on the upper side of the first movement 3 .

[0058] By adopting the above-mentioned technical solution, the bracket 23 can provide a clear guiding path for the net, so that the net sleeve 7 can accurately enter the outside of the first movement 3 from above the first movement 3. During the net renewal process, this helps to avoid the net sleeve 7 from being offset, entangled or misplaced, and ensures that the net sleeve 7 can be smoothly put on the first movement 3, thereby improving the accuracy and efficiency of the net renewal.

[0059] Furthermore, the base 1 is provided with symmetrically arranged clamping rollers 6 for clamping the outer net of the first movement 3. The clamping rollers 6 are connected to a rotating drive so that after the clamping rollers 6 and the first movement 3 clamp the net, the clamping rollers 6 are rotated to transport the net to the net inlet 11.

[0060] By adopting the above-mentioned technical solution, the clamping roller 6 can tightly clamp the mesh on the outside of the first movement 3, and under the action of the rotating drive, the mesh can be stably transported to the mesh inlet 11. For meshes 7 of different materials, the clamping roller 6 can adapt to their characteristics by adjusting the clamping force and conveying speed. For example, for thinner or softer meshes 7, the clamping force and conveying speed can be appropriately reduced to prevent the mesh 7 from being damaged; for thicker or harder meshes 7, the clamping force can be increased and the conveying speed can be increased to ensure that the mesh 7 can be smoothly conveyed.

[0061] Specifically, the clamping roller is located between the bracket and the frame, and the length of the clamping roller on the axis is smaller than the width between the brackets, so that the clamping roller will not interfere with the bracket and the frame during clamping.

[0062] By adopting the above-mentioned technical solution, the clamping roller 6 can tightly clamp the mesh on the outside of the first movement 3, and under the action of the rotating drive, the mesh can be stably conveyed to the mesh inlet 11. For EPE mesh sleeves 7 of different materials, the clamping roller 6 can adapt to their characteristics by adjusting the clamping force and conveying speed. For example, for thinner or softer mesh sleeves 7, the clamping force and conveying speed can be appropriately reduced to prevent the mesh sleeve 7 from being damaged; for thicker or harder mesh sleeves 7, the clamping force can be increased and the conveying speed can be increased to ensure that the mesh sleeve 7 can be smoothly conveyed.

[0063] Furthermore, a rotation counter is provided inside the rotation driver.

[0064] By adopting the above-mentioned technical solution, a rotation counter is set inside the rotary driver, so that the rotary driver can accurately count the length of the net when working, so that the operator can be reminded to renew the net in time through the reminder device. It can also be combined with the control system. The data of the rotation counter can be used to automatically adjust the operating parameters of the equipment. For example, when it is detected that the conveying length of the net sleeve 7 is too long or too short, the rotation speed of the rotary driver or the clamping force of the clamping roller 6 can be automatically adjusted to achieve the best net sleeve 7 conveying effect.

[0065] like Figure 7 As shown: the base 1 is used to support other modules; the self-opening and closing counting module is used to calculate the length of the mesh sleeve, which includes an opening and closing motor 2-1 that provides power for opening and closing movement, and the opening and closing motor 2-1 is fixed to the motor bracket 2-2 by bolts a2-3, and the opening and closing motor 2-1 bracket is fixed to the base 1; one end of the synchronous wheel 2-4 is fixed to the drive motor and transmits power through the synchronous belt 2-5; the movable bracket 2-6 is used to support the fixed shaft; the clamping roller mechanism 2-7 is used to calculate the length of the mesh; the clamping roller mechanism 2-7 is provided with two clamping rollers 6 arranged opposite to each other, which cooperate with each other to clamp the mesh sleeve 7.

[0066] like Figure 8 As shown, the specific structure of the rotation counter is as follows: the clamping roller mechanism includes a linear bearing sleeve a2-7-1, a linear bearing b2-7-2, a synchronous belt pressure plate a2-7-3, a bolt f2-7-4, an encoder 2-7-5, an encoder bracket 2-7-6, a coupling 2-7-7, a bolt g2-7-8, a bracket a2-7-9, a bearing support a2-7-10, a clamping roller 6, a bearing b2-7-12, a support plate a2-7-13 and an adjustable extension frame 2- 7-14; cover plate 2-8-1, bolt h2-8-2, synchronous belt pressure plate b2-8-3, extended bracket 2-8-4, linear bearing sleeve b2-8-5, linear bearing c2-8-6, bolt i2-8-7, bolt j2-8-8, bracket b2-8-9, bearing support b2-8-10, clamping roller 6, and bearing c2-8-12; the drive shaft bracket has an embedded bearing a for supporting the drive shaft; the sensor is secured to the sensor bracket via bolt c. The specific connection between these components is described in CN 118306608A regarding the clamping power mechanism 4 and will not be detailed here.

[0067] The specific steps for re-netting are as follows: Step 1 Preparation of the net sleeve 7: Open the mesh opening of the net sleeve 7, place the net sleeve 7 above the first movement 3, and wait for the net to be threaded.

[0068] Step 2: Mesh threading process: After the mesh opening of the mesh sleeve 7 is opened, pass through the first movement 3 from top to bottom until the mesh opening and the end of the first movement 3 are flush or with a portion left over.

[0069] Step 3 Installation process of the first movement 3: After passing through the mesh, the first movement 3 passes through the roller 51 in the clamping guide assembly 5 from top to bottom. When it contacts the roller 51 in the clamping guide assembly, it triggers the elastic part to deform, causing the roller 51 to move backward. When the roller 51 is located in the middle part of the first movement 3, the elastic part automatically rebounds and clamps the first movement 3.

[0070] Step 4 is to prepare before renewing the network: pass the clamped first movement 3 from top to bottom through the slide rail 12, so that the guide hole of the first movement 3 and the guide column installed on the second movement 4 are matched, and the center alignment is achieved through the tapered structure. After the center alignment, the first movement 3 and the second movement 4 are matched.

[0071] Step 5: Self-opening and closing counting module clamps the mesh sleeve 7: When the above steps are completed, the clamping roller 6 performs a closing movement until the first movement is clamped. At this time, the first movement 3 and the clamping roller 6 cooperate to clamp the mesh sleeve 7.

[0072] Step 6: Continue the net operation: the power roller of the upper clamping power mechanism is opened. At this time, the second movement 4 is constrained by the power roller clamping movement of the lower clamping power mechanism and the guide hole of the first movement 3. Then the power roller of the upper clamping power roller mechanism performs a clamping movement. After the clamping is completed, the lower clamping power mechanism is opened. At this time, the second movement 4 is constrained by the power roller clamping movement of the upper clamping power mechanism and the guide hole of the first movement 3. Then the power roller of the upper clamping power mechanism moves, driving the net sleeve 7 to move downward. The rotation counter set inside the rotary driver counts the length of the falling net. When the net sleeve 7 enters the middle of the power roller of the lower clamping mechanism, the power roller of the upper clamping power mechanism stops rotating, and the power roller of the lower clamping power mechanism performs a clamping movement. After the power roller of the lower clamping power mechanism moves into place, the clamping roller 6 is driven to lower the net at the same time, and the encoder 2-7-5 performs counting operation. When the port of the net sleeve 7 is flush with the outlet of the net machine, the clamping roller 3 stops rotating, the net is continued, and the net operation is waited for.

[0073] Step 7: The net sleeve 7 is used up and taken out for replacement: When the self-opening and closing counting module detects that the net sleeve 7 is used up, the clamping roller mechanism 2-7 will automatically open, and then the net box is taken out, driving the frame 2 to move upward together, and the clamping guide assembly 5 supports the first movement 3, driving the first movement 3 to move upward together until it is completely taken out.

[0074] 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.
