Description

Technical Field

[0001] This utility model relates to the technical field of label application equipment, and in particular to a device for applying labels to the side wall of a treatment agent container. Background Technology

[0002] Metal surface treatment is a crucial step in industrial production, encompassing pretreatment processes such as degreasing, rust removal, phosphating, and rust prevention. These processes require various metal surface treatment agents. Metal surface treatment agents, as a general term for chemical agents used to treat metal surfaces, primarily encompass three categories: cleaning agents, rust inhibitors, and phosphating solutions. Different types of treatment agents must be clearly distinguished by labeling for identification during subsequent storage, transportation, and use.

[0003] In the actual production process of metal surface treatment agents, after the agent is filled into the container, a corresponding label needs to be affixed to the side wall of the container. Currently, the industry mainly uses two labeling methods: one is manual labeling, where the operator holds the label and aligns it with the side wall of the container. This method is not only extremely inefficient and difficult to adapt to the needs of large-scale production, but manual operation is also prone to problems such as label misalignment, air bubbles, and wrinkles, resulting in questionable labeling quality. The other is traditional roller labeling machines. These machines require an additional drive mechanism (such as a motor or gear set) and clamping mechanism to rotate the container to achieve complete labeling. However, since the container is full of agent after filling, it can weigh tens or even hundreds of kilograms. Traditional roller labeling machines require complex transmission and clamping structures to drive the rotation of the heavy container. This not only results in high equipment manufacturing costs but also makes subsequent maintenance difficult and leads to a high failure rate, making it difficult to meet the cost control needs of small and medium-sized production enterprises.

[0004] Based on the shortcomings of the existing technology, there is an urgent need for a labeling device that is suitable for heavy material barrel conveying scenarios, does not require a complex drive mechanism, and can balance labeling efficiency and labeling quality. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] The purpose of this invention is to overcome the shortcomings of low efficiency of manual labeling and complex structure and high cost of traditional rolling labeling machines in the prior art. It provides a device for labeling the side wall of the treatment agent barrel. By utilizing the barrel's own conveying motion and multi-path elastic pressing design, it achieves efficient, low-cost and firm labeling.

[0007] (II) Technical Solution

[0008] An apparatus for attaching labels to the side wall of a treatment agent container, comprising:

[0009] A frame base plate is installed on the side of the end of the conveyor belt of the treatment agent barrel, and the position of the frame base plate corresponds to the conveying path of the conveyor belt, so that the filled barrels conveyed along the conveyor belt can pass through the corresponding area of ​​the frame base plate during the conveying process.

[0010] A labeling core component, mounted on the frame base plate, includes an unwinding assembly, a transition roller group, a label peeling assembly, a traction mechanism, and a rewinding assembly. The unwinding assembly contains a label roll. The label base strip in the label roll passes sequentially through the transition roller group and extends to the label peeling assembly. The label peeling assembly peels the label off the label base strip, and the peeling position corresponds to the conveyor belt's conveying path, so that the side wall of the material bin in the corresponding area of ​​the frame base plate aligns with the peeled label, achieving label adhesion to the side wall of the material bin. The traction mechanism pulls the release paper after the label has been peeled off, and the rewinding assembly rewinds the release paper pulled by the traction mechanism.

[0011] An auxiliary attaching assembly is disposed on the base plate of the frame and on one side corresponding to the label peeling assembly. The auxiliary attaching assembly includes an auxiliary rod, an auxiliary pressure plate, and an auxiliary adhesive plate. One end of the auxiliary rod is connected to the base plate of the frame (it can be relatively movable or fixed), and the other end is connected to the auxiliary pressure plate. The connection structure between the auxiliary rod and the auxiliary pressure plate, or the structure of the auxiliary rod itself, can provide an elastic clamping force pointing towards the material bin. One end of the auxiliary adhesive plate is fixedly connected to the auxiliary pressure plate, and the other end forms a free end. The free end extends towards the center of the conveyor belt so that the material bin being conveyed along the conveyor belt can impact and push the free end. The auxiliary adhesive plate is made of elastic material and can bend and deform away from the label when pushed by the material bin. As the material bin continues to move along the conveyor belt with the label, the elastic restoring force of the auxiliary adhesive plate and the elastic clamping force provided by the auxiliary rod work together to press the label attached to the side wall of the material bin.

[0012] Furthermore: one end of the auxiliary rod is fixedly connected to the conveyor belt, and the auxiliary rod is made of a rigid material with a length-to-diameter ratio greater than a preset threshold; when the material barrel impacts and pushes the auxiliary rubber plate, the auxiliary rubber plate drives the auxiliary pressure plate to move away from the material barrel, thereby causing the auxiliary rod to undergo elastic bending deformation; the elastic restoring force generated after the auxiliary rod bends and deforms constitutes the elastic pressing force pointing towards the material barrel.

[0013] Furthermore: an elastic device is provided between the auxiliary rod and the frame base plate; one end of the elastic device is fixedly connected to the auxiliary rod, and the other end is fixedly connected to the frame base plate, and the elastic device is in a pre-compressed state in the initial state; when the material barrel hits and pushes the auxiliary rubber plate, the auxiliary rubber plate drives the auxiliary pressure plate to move away from the material barrel, so that the elastic device is further compressed; the elastic restoring force of the elastic device constitutes the elastic pressing force pointing towards the material barrel.

[0014] Furthermore: the elastic device is provided with an auxiliary base, a rotating rod and an auxiliary spring. One end of the auxiliary base is fixed to the bottom plate of the frame, and the other end is provided with a rotating groove. One end of the rotating rod is fixed to the auxiliary rod, and the other end is rotatably connected to the rotating groove through a rotating shaft. One end of the auxiliary spring abuts against the rotating rod, and the other end abuts against the side wall of the rotating groove. Its elastic force drives the rotating rod to rotate in the direction of the material bucket.

[0015] Furthermore, the elastic device is also provided with an adjusting seat and an adjusting bolt. The adjusting seat is fixedly connected to the auxiliary base, and the adjusting seat has a spring hole corresponding to the part of the auxiliary spring, so that the auxiliary spring passes through the spring hole. The adjusting bolt is fixedly connected to the adjusting seat in an adjustable manner through the adjusting nut, and forms an elastic adjustment for the auxiliary spring in the spring hole.

[0016] Furthermore, the elastic device is also provided with a first limiting member and a second limiting member, wherein the first limiting member is adjustablely fixed to the side of the rotating groove near the peeling plate, and is used to limit the initial position of the rotating rod; the second limiting member is adjustablely fixed to the side of the rotating groove away from the peeling plate, and is used to limit the rotation position of the rotating rod.

[0017] (III) Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Adaptable to heavy material bins, no complex drive required: This device utilizes the existing conveyor belt movement, combined with the weight of the material bin itself to drive the deformation of the auxiliary rubber plate. There is no need to design an additional motor and clamping mechanism to drive the rotation of the heavy material bin, which greatly simplifies the equipment structure, reduces equipment manufacturing costs and maintenance difficulty, and is especially suitable for small and medium-sized production enterprises.

[0019] 2. Firm adhesion and stable quality: The combined effect of the elastic recovery force of the auxiliary adhesive plate and the elastic clamping force of the auxiliary rod can effectively eliminate air bubbles between the label and the side wall of the material barrel, avoid label wrinkling or falling off, and ensure stable labeling quality.

[0020] 3. High efficiency and easy integration: The device can be directly installed on the side of the end of the existing conveyor belt without the need for large-scale modification of the original production line, making integration convenient; and the labeling process is carried out synchronously with the material barrel conveying process, with a labeling efficiency of 15-30 barrels / minute, which can adapt to the needs of large-scale production.

[0021] 4. Strong compatibility and wide scene adaptation: The elastic clamping force of the auxiliary rod can be achieved through multiple paths, and the clamping force can be adjusted according to the weight of different material buckets (20-100kg) and label materials (paper, plastic), adapting to labeling scenarios of various treatment agent buckets.

[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Please see Figures 1 to 6 In this embodiment of the invention, to achieve the above objective, the invention provides a device for attaching labels to the side wall of a treatment agent container. The specific technical solution is as follows:

[0034] The device includes a frame base plate 10, a labeling core component, and an auxiliary labeling component. The structure and connection relationship of each component are as follows:

[0035] 1. Frame base plate 10

[0036] The frame base plate 10 serves as the fundamental support structure of the device. Made of metal (such as stainless steel or aluminum alloy), it possesses sufficient strength to support the labeling core components and auxiliary application components. The frame base plate 10 is installed on the side of the end of the conveyor belt 50 of the treatment agent tank via a four-axis adjustment mechanism, as is common in the prior art. Its installation position must precisely correspond to the conveying path of the conveyor belt 50. The four-axis adjustment mechanism can adjust the height and horizontal position of the entire device, ensuring that the label peeled off by the peeling plate 16 can be accurately aligned with the labeling area on the side wall of the tank. Specifically, the distance between the edge of the frame base plate 10 and the side of the conveyor belt 50 is 5-15cm, and the areas where the label peeling components 15 and auxiliary application components are located on the frame base plate 10 must correspond to the conveying direction of the conveyor belt 50. This ensures that the filled tanks (typically weighing 20-100kg) conveyed at a uniform speed along the conveyor belt 50 can smoothly pass through the functional area of ​​the corresponding components on the frame base plate 10 during transport, without requiring additional adjustments to the tank's conveying trajectory.

[0037] 2. Labeling core components

[0038] The labeling core component is mounted on the frame base plate 10. Along the conveying direction of the label base tape, the unwinding assembly 11, the transition roller group 14, the label peeling assembly 15, the traction mechanism 20, and the rewinding assembly 24 are arranged in sequence. All components work together to peel off the label and recycle the release paper.

[0039] Unwinding assembly 11: includes unwinding shaft 12 and damper 13. Unwinding shaft 12 is used to mount label roll (label roll is composed of label and release paper). Damper 13 is used to control the unwinding speed of label roll to prevent the baseband from loosening due to excessive unwinding of label roll due to inertia.

[0040] Transition roller group 14: Composed of 2-4 guide rollers, the axis of the guide rollers is perpendicular to the conveying direction of the conveyor belt 50, and is used to guide the label roll from the unwinding assembly 11 to the label peeling assembly 15 to ensure that the label roll moves smoothly along the preset path;

[0041] Label peeling assembly 15: includes a label peeling plate 16, one end of which is a sharp label peeling blade (blade angle is 30°-60°). When the label roll passes around the label peeling blade, the release paper turns along the label peeling blade due to its material characteristics (such as being thin and flexible), while the label separates from the release paper due to its adhesiveness, thus achieving label peeling.

[0042] Traction mechanism 20: includes active traction roller 22 and driven pressure roller 23. The active traction roller 22 is driven by micro motor 21. The driven pressure roller 23 cooperates with the active traction roller 22 to clamp the release paper. The rotation of the active traction roller 22 drives the release paper to be conveyed to the winding assembly 24, providing power for the overall movement of the label roll.

[0043] The winding assembly 24 includes a winding shaft 25 and a transmission mechanism. The winding shaft 25 and the transmission mechanism are connected by a coupling. The transmission mechanism drives the winding shaft 25 to rotate, winding and recovering the release paper conveyed by the traction mechanism 20, thus preventing the release paper from scattering and polluting the production environment. The transmission mechanism includes synchronous pulleys respectively installed at the ends of the active traction roller 22 and the winding shaft 25. The two synchronous pulleys are connected by a synchronous belt, with a transmission ratio of 1:1, ensuring that the linear speeds of the traction mechanism 20 and the winding assembly 24 are consistent, preventing the release paper from stretching or loosening. The transmission mechanism can form a transmission connection with the traction mechanism 20 through the transmission structure of the synchronous pulleys and synchronous belt, thereby enabling the micro motor 21 of the traction mechanism 20 to synchronously drive the winding shaft 25 to rotate.

[0044] 3. Auxiliary attachment components

[0045] The auxiliary labeling component is mounted on the base plate 10 of the frame and corresponds to one side of the label peeling component 15 (the side closest to the conveyor belt 50). It is used to press the label firmly against the side wall of the hopper after the label is peeled off, ensuring that the label is firmly attached. It includes an auxiliary rod 30, an auxiliary pressure plate 31, and an auxiliary adhesive plate 32.

[0046] Auxiliary rod 30: One end is connected to the frame base plate 10 or the side plate of the conveyor belt 50 (the connection method can be selected according to actual needs, such as relatively movable connection or fixed connection), and the other end is connected to the auxiliary pressure plate 31. The connection structure between the auxiliary rod 30 and the frame base plate 10 or the structure of the auxiliary rod 30 itself can provide an elastic clamping force pointing towards the material barrel. This elastic clamping force is the core functional feature of the auxiliary attachment component and can be achieved through multiple paths to adapt to the clamping requirements of different production scenarios.

[0047] Auxiliary pressure plate 31: Made of rigid plastic or metal, it has a rectangular plate structure and is used to evenly transfer the elastic force of the auxiliary rod 30 to the auxiliary adhesive plate 32, so as to avoid uneven local force on the auxiliary adhesive plate 32 and thus avoid label misalignment.

[0048] Auxiliary rubber plate 32: Made of elastic material (such as silicone or nitrile rubber), with a thickness of 3-8mm (the thickness of the auxiliary rubber plate 32 can be appropriately increased for larger barrel diameters; for example, a thickness of 5-8mm is suitable for barrels with a diameter of 50cm or more, and a thickness of 3-5mm is suitable for barrels with a diameter of less than 50cm). It has good flexibility and wear resistance. One end of the auxiliary rubber plate 32 is fixedly connected to the auxiliary pressure plate 31 by bolts or adhesive, and the other end forms a free end, which extends 5-10cm toward the center of the conveyor belt 50. This ensures that when the barrels are conveyed along the conveyor belt 50, they can accurately impact and push the free end of the auxiliary rubber plate 32. When the auxiliary rubber plate 32 is pushed by the barrel, it will bend and deform to the side away from the label. The elastic recovery force generated during its deformation can initially press the label against the side wall of the barrel. At the same time, the elastic pressing force provided by the auxiliary rod 30 will work together with the elastic recovery force of the auxiliary rubber plate 32 to further improve the tightness of the label and prevent the label from escaping or falling off during the movement of the barrel.

[0049] The operation of this device requires coordination with the conveyor belt 50. The specific steps are as follows:

[0050] Step 1: Equipment initialization - Place the label roll onto the unwinding shaft 12 of the unwinding assembly 11, and pull the free end of the label roll to pass sequentially between the transition roller group 14, the peeling blade of the peeling assembly 15, the active traction roller 22 and the driven pressure roller 23 of the traction mechanism 20, and finally fix it on the winding shaft 25 of the winding assembly 24; adjust the position of the peeling assembly 15 so that the peeled label is aligned with the labeling area on the side wall of the material barrel on the conveyor belt 50.

[0051] Step 2: Material barrel conveying and label peeling - The conveyor belt 50 drives the filled material barrel to be conveyed at a speed of 0.5-1m / s. The traction mechanism 20 and the winding assembly 24 are started in advance (starting time is 1-2 seconds earlier than the material barrel approaches the label peeling assembly 15). The label roll moves along the transition roller group 14 towards the label peeling assembly 15. The label is separated from the release paper at the label peeling blade. When the material barrel approaches the label peeling assembly 15, the peeled label is in the state of waiting to be attached.

[0052] Step 3: Assisted Labeling Pressing – The material hopper continues to move along the conveyor belt 50, and its side wall impacts the free end of the auxiliary rubber plate 32, pushing the auxiliary rubber plate 32 to bend and deform away from the label. At the same time, the side wall of the material hopper comes into contact with the peeled label. The label has its own adhesive backing and initially adheres to the side wall of the material hopper under the action of adhesion. As the material hopper continues to move, the elastic restoring force of the auxiliary rubber plate 32 and the elastic pressing force of the auxiliary rod 30 work together to press the label tightly against the side wall of the material hopper, completing the labeling process.

[0053] Step 4: Release paper recycling - The traction mechanism 20 continuously pulls the release paper after the label is peeled off, and the winding component 24 simultaneously winds and recycles the release paper until the material barrel completely leaves the working area of ​​the auxiliary labeling component, and the device enters the next labeling cycle.

[0054] To further illustrate the technical solution of this utility model, the following detailed description is provided in conjunction with specific embodiments. All embodiments are based on the above-mentioned core technical solution, with differences only in the path of achieving the elastic clamping force of the auxiliary rod 30.

[0055] Example 1: Auxiliary rod 30 fixed connection (self-elastic bending)

[0056] like Figure 1 and Figure 4 As shown, preferably, in this embodiment, the auxiliary rod 30 and the side plate of the conveyor belt 50 are fixedly connected, and the elastic clamping force is provided by the elastic bending of the auxiliary rod 30 itself. The specific structure is as follows:

[0057] The auxiliary rod 30 is made of metal (such as spring steel), with a length of 30-50cm, a diameter of 5-8mm, and a length-to-diameter ratio of 6-10 (greater than the preset threshold), and has good elastic bending performance. The lower end of the auxiliary rod 30 is fixedly connected to the side plate of the conveyor belt 50 via the auxiliary side strip 33 and the auxiliary extension plate 34, and the upper end is fixedly connected to the auxiliary pressure plate 31. The fixed connection can be made by welding or bolts. The auxiliary side strip 33 has elongated adjustment holes along the conveying direction of the conveyor belt 50. It is fixed to the side plate of the conveyor belt 50 by bolts passing through the adjustment holes. Loosening the bolts allows the auxiliary side strip 33 to slide along the conveying direction, thereby adjusting the position of the auxiliary rod 30 along the conveying direction of the conveyor belt 50. The adjustment range is set to 0-15cm (suitable for labeling areas of material buckets with a length of 30-60cm). The auxiliary extension plate 34 is perpendicular to the conveying direction of the conveyor belt 50. One end is fixed to the auxiliary side strip 33 by bolts or welding, and the other end has a waist-shaped hole. The auxiliary rod 30 can be adjusted and fixed in the waist-shaped hole by nuts. By loosening the nuts, the position of the auxiliary rod 30 in the waist-shaped hole can be adjusted to achieve the distance between the auxiliary rod 30 and the side plate of the conveyor belt 50. The adjustment range is set to 5-20cm (suitable for the distance between the side walls of material buckets with a diameter of 20-50cm). By adjusting the auxiliary edge strip 33 and the auxiliary extension plate 34 in both directions, it can be ensured that the free end of the auxiliary adhesive plate 32 is always aligned with the preset labeling area on the side wall of the material barrel (the deviation is controlled within ±2mm), avoiding label misalignment and wrinkles caused by the position offset of the auxiliary rod 30. At the same time, it is compatible with treatment agent barrels of different specifications from 20-100kg, improving the scene adaptability of the device.

[0058] When the material barrel hits the free end of the auxiliary rubber plate 32, the auxiliary rubber plate 32 drives the auxiliary pressure plate 31 to move away from the material barrel. Since the auxiliary rod 30 has a large length-to-diameter ratio and the material is elastic, the auxiliary rod 30 will bend and deform to the side away from the material barrel. The elastic recovery force generated by the bending deformation of the auxiliary rod 30 constitutes the elastic pressing force, which works together with the elastic recovery force of the auxiliary rubber plate 32 to press the label.

[0059] After the material bucket leaves, the elastic restoring force of the auxiliary rod 30 drives the auxiliary pressure plate 31 and the auxiliary rubber plate 32 to reset. The structure is simple and does not require additional elastic components, resulting in low maintenance costs.

[0060] The advantages of this embodiment are: no additional elastic components (such as springs), reducing the number of vulnerable parts of the equipment, avoiding spring failure due to dust accumulation, reducing the frequency of subsequent maintenance, and making it suitable for harsh production environments (such as those with a lot of dust).

[0061] Example 2: An elastic device 40 is provided between the auxiliary rod 30 and the frame base plate 10.

[0062] like Figure 2 , Figure 5 and Figure 6As shown, preferably, in this embodiment, an elastic device 40 is added between the auxiliary rod 30 and the frame base plate 10 to provide elastic clamping force. The specific structure is as follows:

[0063] The elastic device 40 is provided with an auxiliary base 41, a rotating rod 43 and an auxiliary spring 44. One end of the auxiliary base 41 is fixed to the bottom plate 10 of the frame, and the other end is provided with a rotating groove 42. One end of the rotating rod 43 is fixed to the auxiliary rod 30, and the other end is rotatably connected to the rotating groove 42 through a rotating shaft. One end of the auxiliary spring 44 abuts against the part of the rotating rod 43 away from the rotating shaft, and the other end of the auxiliary spring 44 abuts against the side wall of the rotating groove 42 away from the label peeling plate 16, so that the elastic force of the auxiliary spring 44 can drive the rotating rod 43 to rotate towards the material barrel, ensuring that the auxiliary rubber plate 32 can fit against the side wall of the material barrel.

[0064] Specifically, the auxiliary base 41 is bolted to the side of the frame base plate 10 where the label peeling plate 16 is mounted. One end of the base 41, which has a rotating groove 42, protrudes from the frame base plate 10, allowing the end of the rotating rod 43 extending into the rotating groove 42 to be rotatably connected to the rotating groove 42 via a rotating shaft. One end of the auxiliary spring 44 abuts against the part of the rotating rod 43 away from the rotating shaft, and the other end of the auxiliary spring 44 abuts against the side wall of the rotating groove 42 away from the label peeling plate 16, so that the elastic force of the auxiliary spring 44 can drive the rotating rod 43 to rotate towards the label peeling plate 16.

[0065] Secondly, when the material hopper pushes the auxiliary adhesive plate 32 and the auxiliary pressure plate 31, the auxiliary pressure plate 31 drives the rotating rod 43 to rotate along its axis via the auxiliary rod 30, and compresses the auxiliary spring 44 in the rotating groove 42, causing the auxiliary spring 44 to deform. The elastic restoring force of the auxiliary spring 44 constitutes the elastic pressing force of the auxiliary rod 30, which, together with the elastic restoring force of the auxiliary adhesive plate 32, improves the label pressing degree. When the material hopper leaves, the auxiliary spring 44 pushes the rotating rod 43 to return to its original position. Its structure is compact and the elastic force is uniform, making it suitable for scenarios with high labeling accuracy requirements (such as when the label edge needs to be aligned with the edge of the material hopper).

[0066] Both of the above embodiments can achieve the core function of "the auxiliary rod 30 providing elastic clamping force". By simply adjusting the connection method of the auxiliary rod 30 or the setting position of the elastic component, it can be adapted to different production needs, further demonstrating the flexibility and compatibility of this utility model.

[0067] like Figure 5 and Figure 6As shown, preferably, the elastic device 40 is further provided with an adjusting seat 45 and an adjusting bolt 46. The adjusting seat 45 is fixedly connected to the auxiliary base 41. The adjusting seat 45 has a spring hole at the part corresponding to the auxiliary spring 44, so that the auxiliary spring 44 passes through the spring hole. The adjusting bolt 46 is fixedly connected to the adjusting seat 45 in an adjustable manner through the adjusting nut, and forms an elastic adjustment for the auxiliary spring 44 in the spring hole.

[0068] Specifically, to further optimize the clamping force of the auxiliary adhesive plate 32 and the auxiliary pressure plate 31 on the label, preferably, an adjustment seat 45 and an adjustment bolt 46 are also provided. The adjustment hole accommodates a relatively long auxiliary spring 44, allowing the length of the auxiliary spring 44 to be adjusted by the adjustment bolt 46 within the adjustment hole, thereby changing its elastic force. This allows for more precise adjustment of the label clamping force.

[0069] like Figure 5 and Figure 6 As shown, preferably, the elastic device 40 is further provided with a first limiting member 47 and a second limiting member 48, wherein the first limiting member 47 is adjustablely fixed to the side of the rotating groove 42 near the peeling plate 16, and is used to limit the initial position of the rotating rod 43; the second limiting member 48 is adjustablely fixed to the side of the rotating groove 42 away from the peeling plate 16, and is used to limit the rotation position of the rotating rod 43.

[0070] Specifically, because the auxiliary spring 44 continuously drives the rotating rod 43 with elastic force, the auxiliary rubber plate 32 and the auxiliary pressure plate 31 tend to rotate towards the peeling plate 16, or even directly impact the peeling plate 16, affecting the peeling of the label. Therefore, a first limiting member 47 can be provided on the side wall of the rotating groove 42 near the peeling plate 16 to limit the initial angle of the rotating rod 43, keeping it at a suitable distance from the peeling plate 16. When the material barrel pushes the auxiliary rubber plate 32, in order to prevent the rotating rod 43 from directly impacting the side wall of the rotating groove 42, a second limiting member 48 can be provided on the side wall of the rotating groove 42 away from the peeling plate 16 to limit the rotation angle of the rotating rod 43, so that after being pushed by the material barrel and rotating by a preset angle, it stops at the position of the second limiting member 48.

[0071] Secondly, the first limiting member 47 and the second limiting member 48 can be set using ball screws in the prior art, and the spring inside the ball screw can be used to buffer the rotating rod 43; at the same time, the limiting distance of the limiting member can be adjusted by using a nut.

[0072] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
