Description

Technical Field

[0001] This utility model relates to the field of yarn production technology, specifically to a doffing device for a spinning frame used in yarn production. Background Technology

[0002] The spinning frame is the main machine for spinning yarn; doffing is the process of removing all the full bobbins of yarn from the spinning frame. Traditionally, manual doffing is used, which is too inefficient. In order to improve the efficiency of doffing, most factories now use doffing devices.

[0003] The patent document, published under CN220538026U, entitled "A Doffing Device for a Fine Spinning Machine in Polyester Yarn Production," describes a device that uses a double-headed motor to clamp the yarn bobbin, then uses an electric push rod to move the yarn bobbin upwards and remove it, and finally uses a drive motor to move the yarn bobbin to the inside of the doffing box. The entire process requires the operation and control of three electrical components, which is cumbersome and results in low doffing efficiency. Furthermore, the three electrical components also lead to high energy consumption and high cost. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a doffing device for a spinning frame used in yarn production, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a doffing device for a spinning machine for yarn production, comprising a movable box and a bracket set on the spinning machine, wherein support rods are evenly arranged on the bracket and full tubes of yarn are sleeved on the support rods;

[0006] The movable box is equipped with a lifting component, which is connected to a clamping component. The clamping component is used to clamp or release several full tubes of yarn simultaneously. The lifting component is also connected to a transmission component, which is connected to a guide trough for receiving the full tubes of yarn. The guide trough gradually slopes upward from left to right, and the movable box is equipped with an inclined rail that is slidably connected to the guide trough. The lifting component drives the guide trough to move along the inclined rail through the transmission component.

[0007] Preferably, the lifting assembly includes a gear frame connected to the clamping assembly, a guide rod is provided at the bottom of the gear frame, the guide rod is vertically slidably connected to the movable box, and an electric telescopic rod connected to the gear frame is provided on the movable box.

[0008] Preferably, the transmission assembly includes two rotating shafts, both of which are connected to the movable box via bearings. Each of the two rotating shafts is provided with a first gear and a second gear. The right side of the first gear is meshed with a gear frame, and the bottom of each second gear is meshed with a guide groove.

[0009] Preferably, the radius of gear one is smaller than the radius of gear two.

[0010] Preferably, the bracket is provided with a guide rail that is slidably connected to the movable box.

[0011] Preferably, the mobile box is provided with a handle, and the handle is provided with a control panel.

[0012] Preferably, the bottom of the inner wall of the mobile box is provided with a sloping plate that is higher on the left and lower on the right.

[0013] This utility model provides a doffing device for a spinning frame in yarn production. Compared with the prior art, it has the following advantages:

[0014] 1. The doffing device for a spinning machine used in yarn production, when the lifting component drives the clamping component to move downward, the transmission component drives the guide chute to move to the lower left along the inclined rail, thus avoiding the clamping component. This allows the clamping component to move down to the full bobbin and clamp the full bobbin. After clamping, the lifting component drives the clamping component to move upward, which in turn moves the full bobbin upward, causing the guide chute to reset and move below the clamping component. At this point, the full bobbin can be released, allowing it to fall into the moving box through the guide chute. Compared with existing technologies, this device only requires two electrical components—an electric telescopic rod and a clamping component—to complete the doffing process. It has the advantages of simple operation, high efficiency, low energy consumption, and low cost.

[0015] 2. The doffing device of the spinning machine for yarn production can guide the movement of the moving box through the guide rail, so that the clamping component can clamp the full tube of yarn after it falls, thereby improving the doffing efficiency. Attached Figure Description

[0021] 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.

[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] First embodiment: A yarn doffing device for a spinning frame for yarn production includes a movable box 1 and a bracket 2 set on the spinning frame. Support rods 3 are evenly arranged on the bracket 2, and full tube yarns 4 are sleeved on the support rods 3.

[0024] The movable box 1 is equipped with a lifting assembly, which is connected to the clamping assembly 5. The clamping assembly 5 is used to simultaneously clamp or release several full-bore yarns 4. This can be achieved using existing technology, such as connecting multiple bidirectional lead screws to each other and driving them with a motor to rotate synchronously. Clamping plates are screwed to both ends of each bidirectional lead screw, allowing the clamping plates to clamp or release synchronously. The lifting assembly is also connected to a transmission assembly, which is connected to a guide trough 6 for receiving the full-bore yarns 4. The guide trough 6 gradually slopes upward from left to right, and the movable box 1 is equipped with a sloping rail 13 that is slidably connected to the guide trough 6. The lifting component drives the guide chute 6 to move along the inclined rail 13 via the transmission component. When the lifting component drives the clamping component 5 to move downward, the transmission component drives the guide chute 6 to move to the lower left along the inclined rail 13 to avoid the clamping component 5. This allows the clamping component 5 to move down to the full tube yarn 4 and clamp the full tube yarn 4. After clamping, the lifting component drives the clamping component 5 to move upward, causing the full tube yarn 4 to move upward and away from the support rod 3. Under the action of the transmission component, the guide chute 6 can be reset to the upper right corner and moved below the clamping component 5. At this time, the full tube yarn 4 can be released and fall into the moving box 1 through the guide chute 6.

[0025] The lifting assembly includes a gear frame 7 connected to the clamping assembly 5. A guide rod 8 is provided at the bottom of the gear frame 7. The guide rod 8 is vertically slidably connected to the movable box 1. An electric telescopic rod 9 connected to the gear frame 7 is provided on the movable box 1. The guide rod 8 can guide the lifting of the gear frame 7.

[0026] The transmission assembly includes two rotating shafts 10, both of which are connected to the movable box 1 via bearings. Each of the two rotating shafts 10 is equipped with a first gear 11 and a second gear 12. The right side of the first gear 11 is meshed with the gear frame 7, and the bottom of the two second gears 12 is meshed with the guide chute 6. When the gear frame 7 moves down, the first gear 11, the second gear 12, and the rotating shaft 10 all rotate clockwise, allowing the guide chute 6 to move to the lower left corner.

[0027] The radius of gear 11 is smaller than that of gear 212, which allows the guide chute 6 to move a greater distance than the clamping assembly 5 when the clamping assembly 5 is raised or lowered. This allows the guide chute 6 to complete the avoidance action without the clamping assembly 5 having a very high initial height.

[0028] The bracket 2 is equipped with a guide rail 14 that is slidably connected to the movable box 1, which can guide the movement of the movable box 1 so that the clamping component 5 can clamp the full tube yarn 4 after it falls, thereby improving the efficiency of yarn doffing.

[0029] The second embodiment differs from the first embodiment in that the movable box 1 is provided with a handle 15, and the handle 15 is provided with a control panel 16, which facilitates the control of the electric telescopic rod 9 and the clamping assembly 5.

[0030] The bottom of the inner wall of the movable box 1 is provided with a sloping plate 17 that is higher on the left and lower on the right, so that the full tube yarn 4 falling along the guide chute 6 will not accumulate on the left side of the inner wall of the movable box 1.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the movable box 1 is pushed by the handle 15 along the guide rail 14. Then, the lifting component is controlled by the control panel 16 to move the clamping component 5 downward. The transmission component then moves the guide chute 6 to the lower left to avoid the downward-moving clamping component 5, so that the clamping component 5 moves down to clamp the full tube yarn 4. After clamping, the lifting component moves the clamping component 5 upward, moving the full tube yarn 4 away from the support rod 3. This allows the guide chute 6 to reset and move below the clamping component 5. At this point, the full tube yarn 4 can be released and fall into the movable box 1 through the guide chute 6. Repeating the above steps will remove all the full tube yarn 4 from the bracket 2 and put them into the movable box 1. Finally, the movable box 1 is detached from the guide rail 14.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] 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.
