Description

Technical Field

[0001] This utility model relates to the technical field of silkworm cocoon processing equipment, specifically to an adjustable square cluster cocoon removal machine, which is suitable for removing and correcting cocoons with square clusters of different specifications. Background Technology

[0002] In the silkworm cocoon processing industry, paper grid clusters have become the mainstream cocoon-forming carrier due to their good hygroscopicity. However, they are prone to softening and deformation under stress and moisture, making it difficult to maintain the rectangular shape of the small grids during cocoon removal. Traditional cocoon removal equipment generally suffers from problems such as poor correction effect of deformed grid clusters, easy damage to grid clusters by inserted parts, and cumbersome and time-consuming adjustment for specification adaptation.

[0003] Although the paper grid cluster adjuster and the cocoon removal machine using the adjuster disclosed in Chinese Publication No. CN218126440U have an adjustment device, they employ a complex linkage mechanism with multiple components such as hand cranks and pry bars. This results in numerous parts, high cost, and complex maintenance. The rigid pushing of the upper and lower adjustment parts against the grid clusters easily causes damage. Furthermore, the adjustment relies on manual, sequential calibration without graduation markings, leading to long setup times and low efficiency, making it difficult to meet actual production needs. Therefore, there is an urgent need for a cocoon removal device with a simple structure, convenient adjustment, and flexible correction capabilities to solve the problems of high cost and high damage caused by complex mechanical linkages in existing technologies, achieving efficient adaptation and low-damage cocoon removal for paper grid clusters of different specifications. Utility Model Content

[0004] This utility model overcomes the shortcomings of the above-mentioned technology and adopts the following technical solution:

[0005] An adjustable square cluster cocoon removal machine includes a frame 10, a mounting frame 20 mounted on the frame, and a cocoon removal device 30 mounted above the mounting frame. The mounting frame 20 is provided with an adjusting frame 21, which includes a front frame 22 and a rear frame 23. The upper and lower surfaces of the front frame 22 and the rear frame 23 are provided with arc-shaped guide grooves 24. The mounting frame 20 is provided with a fixing rod 25 that passes through the arc-shaped guide grooves 24, which is used to allow the front frame 22 and the rear frame 23 to slide relative to each other along an arc-shaped trajectory. Multiple sets of insertion pieces 40 are connected to the inner side of the adjusting frame 21, which are used to insert and correct deformed squares of the square cluster. The mounting frame 20 is provided with at least two adjustable limiting blocks 50, which are fixed by adjusting bolts 51, to limit the maximum sliding stroke of the adjusting frame 21.

[0006] Furthermore, the limiting block 50 is provided with an elongated waist hole 52, through which the adjusting bolt 51 passes and is connected to the mounting bracket 20; the surface of the limiting block 50 is provided with a scale mark 53, which is used to adjust the position of the adjusting bolt 51 corresponding to different specifications of square clusters and lock it at the preset scale mark 53.

[0007] Furthermore, the upper parts of both sides of the front frame 22 are respectively hinged to the first drive rod 60 for driving the front frame 22 to slide backward; the lower parts of both sides of the rear frame 23 are respectively hinged to the second drive rod 70 for driving the rear frame 23 to slide forward.

[0008] Furthermore, the first drive rod 60 and the second drive rod 70 are connected by a linkage mechanism 61; the linkage mechanism 61 is provided with a crossbar 62 for receiving downward pressure to drive the linkage.

[0009] Furthermore, the insert piece 40 is horizontally mounted on the inner side of the adjustment frame 21 via the slot 41; the insert piece 40 of the front frame 22 slides backward synchronously with the front frame 22, and the insert piece 40 of the rear frame 23 slides forward synchronously with the rear frame 23, for expanding the grid cluster.

[0010] Furthermore, the arc-shaped guide grooves 24 of the front frame 22 and the rear frame 23 are symmetrical arc-shaped structures.

[0011] Furthermore, the insert 40 has an arc structure 42 at its end to reduce damage to the grid clusters.

[0012] Furthermore, the cocoon removal device 30 is provided with a cocoon removal column 31, the bottom of which has a conical structure to reduce damage to the grid clusters.

[0013] Furthermore, it also includes a lifting drive mechanism 80, which comprises:

[0014] Vertical guide rails 81 are symmetrically fixed on both sides of the frame 10;

[0015] A lifting frame 82 is slidably mounted on a guide rail 81, and the cocoon remover 30 is fixed to the lifting frame;

[0016] Foot pedal 83, the front end of which is hinged to the bottom of frame 10;

[0017] The transmission link 84 is hinged at one end to the end of the foot pedal 83 and at the other end to the lifting frame 82.

[0018] The return spring 85 is connected at one end to the frame 10 and at the other end to the foot pedal 83.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The complex multi-component linkage mechanism of traditional cocoon removal machines, such as hand cranks, linkage mechanisms, and pry bars, has been simplified by adopting a simple structure combining a single-sided adjustable limit block and an arc-shaped guide groove. This minimalist design not only reduces the number of parts and lowers production costs, but also greatly simplifies the assembly and maintenance process of the equipment.

[0021] 2. The limit block surface is marked with clear scale markings that correspond to different sizes of square clusters. Operators can intuitively adjust the limit block to the accurate position according to the specifications of the square clusters and lock it with the adjusting bolts, thus realizing visual adjustment.

[0022] 3. The insert plate adopts a special design. Its arc structure at the end effectively avoids rigid contact with the grid cluster, changing the contact method from point contact or line contact to surface contact, thereby greatly reducing the risk of damage to the grid cluster.

[0023] 4. The unique adjustment frame and adjustable limit block design enable the cocoon removal machine to quickly and accurately adapt to various sizes of paper grid clusters. By simply adjusting the position of the limit block, it is easy to adapt to different sized grid clusters, eliminating the need for complicated manual adjustments, greatly reducing the time spent on each adjustment, and improving production efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] 1. Overall equipment assembly and connection of core components

[0030] like Figures 1-4 As shown, the top of the frame 10 is fixed with a mounting bracket 20. The adjusting frame 21 consists of a front frame 22 and a rear frame 23. The two frames are connected to the fixing rod 25 of the mounting bracket 20 via symmetrical arc-shaped guide grooves 24 on their upper and lower surfaces, forming an arc-shaped sliding pair. The front frame 22 and the rear frame 23 are linked by a first drive rod 60, a second drive rod 70, and a linkage mechanism 61: when the crossbar 62 is pressed down, the first drive rod 60 pulls the front frame 22 to slide backward along the fixing rod 25, and the second drive rod 70 pushes the rear frame 23 to slide forward, thereby realizing the symmetrical expansion of the insert piece 40.

[0031] The limiting block 50 is installed on one side of the mounting bracket 20 through the waist hole 52 and the adjusting bolt 51. The scale markings 53 on its surface indicate the adjustment positions corresponding to the grid cluster specifications such as "10mm", "15mm", and "20mm". The insert plate 40 is horizontally fixed to the inside of the adjusting frame through the slot 41. The radius of the arc structure 42 at the end is 2.5mm. When it comes into contact with the inner wall of the grid cluster, it produces an elastic deformation of 0.5-2mm to avoid rigid damage.

[0032] 2. Specification Adaptation Operation Procedure

[0033] Quick adjustment: According to the side length of the square cluster, such as 15mm, loosen the adjusting bolt 51 and slide the limit block 50 to the scale "15". At this time, the sliding stroke of the fixing rod 25 in the arc guide groove 24 is restricted, so that the maximum opening distance of the insert piece 40 is 17mm with a 2mm correction allowance. The adjustment time is ≤10 seconds.

[0034] Synchronous expansion: The lower crossbar 62 and the linkage mechanism 61 drive the front frame 22 and the rear frame 23 to slide relative to each other along a symmetrical arc trajectory. The insert piece 40 evenly expands the deformed squares. The correction force is controlled within the range of 1-3N through the arc guide groove with a curvature radius R=50mm to avoid tearing of the paper squares.

[0035] 3. Cocoon removal process

[0036] a. Initial state preparation

[0037] Cocoon removal device reset: When the foot pedal 83 is not stepped on, the reset spring 85 is in a naturally extended state, and the lifting frame 82 drives the cocoon removal device 30 to the top of the vertical guide rail 81 to avoid interfering with the operation of the mounting frame 20.

[0038] Mounting bracket ready: Mounting bracket 20 is slidably connected to frame 10 via bottom groove. The initial position is the pushed-in state. Adjusting frame 21 is closed in the initial state, and the spacing of insert pieces 40 is at its minimum.

[0039] b. Place the grid cluster

[0040] Pull out the mounting bracket: Manually pull the mounting bracket 20 outward along the slide groove to the limit position to expose the upper operating table surface.

[0041] Positioning of the square cluster: Place the square cluster to be removed from the cocoon flat on the mounting frame 20, align it with the center of the adjustment frame 21, and press the edges of the square cluster with the adjustable blocks on the four sides of the mounting frame to prevent it from shifting during removal from the cocoon.

[0042] Initial specification adjustment: Based on the size of the square cluster holes, initially slide the limit block 50 to the corresponding scale, such as aligning the 15mm specification with the "15" scale, but it does not need to be completely locked, leaving room for fine adjustment.

[0043] c. Adjust the pre-opening of the frame

[0044] Manual pre-tensioning of the insert piece: Lightly press the crossbar 62 and drive the linkage mechanism 61. The linkage mechanism 61 rotates and simultaneously drives the first drive rod 60 and the second drive rod 70. The first drive rod 60 drives the front frame 22 to move backward, and the second drive rod 70 drives the rear frame 23 to move forward, so that the insert piece 40 slowly opens to a size slightly smaller than the size of the square cluster holes, such as opening a 15mm hole to 14mm, ensuring that the insert piece can smoothly enter the deformed hole.

[0045] Fine calibration: Observe the alignment of the insert 40 with the grid, fine-tune the position of the limit block 50 to ensure that the center of the insert 40 is aligned with the center of the grid, tighten the adjusting bolt 51 to fix it, and complete the equipment adjustment for this specification of grid cluster.

[0046] d. Execution of the "Emerging from the Cocoon" procedure

[0047] Push back the mounting bracket: Push the mounting bracket 20 back into the frame 10 along the slide groove until it fits against the front positioning surface of the frame, ensuring that the cocoon remover is vertically aligned when it descends.

[0048] Foot-operated cocoon removal: Stepping smoothly on the foot pedal 83, the transmission linkage 84 pulls the lifting frame 82 down at a constant speed along the vertical guide rail 81. The conical bottom of the cocoon removal column 31 first inserts into the top hole of the square cluster, and then the insert plate 40 fully opens to correct the square to a rectangle. At the same time, the cocoon is pushed off the square by the cocoon removal column.

[0049] Force control: Control the force of cocoon removal by stepping on the foot pedal to avoid damaging the square clusters due to excessive speed.

[0050] e. Resetting and unloading

[0051] Release the foot pedal: After the cocoon removal is completed, slowly release the foot pedal 83. The return spring 85 will drive the cocoon removal device 30 to rise automatically to the initial position, and the insertion plate 40 will close synchronously with the adjustment frame 21.

[0052] Remove the square cluster: Pull out the mounting bracket 20 again, remove the square cluster that has emerged from the cocoon, clean up any remaining cocoons and debris, and prepare for the next cycle.

[0053] 4. Maintenance and Expansion

[0054] Easy maintenance: The insert plate 40 can be quickly replaced through the slot 41 to adapt to different wear levels or specifications; the combination of the limit block 50 and the adjusting bolt 51 can be disassembled and cleaned without professional tools.

[0055] Expanding applications: By replacing the arc-shaped guide groove 24 with different curvatures or adjusting the elastic coefficient of the return spring 85, it can be compatible with grid clusters made of wood chips, plastics, and other materials, thus expanding the range of applications of the equipment.

[0056] This invention overcomes the technical bottlenecks of low adaptation efficiency and high damage rate of existing cocoon removal machines through its minimalist mechanical structure and flexible correction design. Its synergistic solution of single-sided limiting block and arc-shaped guide groove not only reduces the number of parts and production costs, but also further reduces the damage rate of square clusters through visual adjustment and elastic contact, significantly improving the automation level and economic benefits of silkworm cocoon processing, and has broad industrial application value.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
