Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a fabric flattening and cutting machine for producing four-piece bedding sets. Background Technology

[0002] In people's daily lives, a four-piece bedding set usually refers to a four-piece bedding set. As the name suggests, it is a bedding set consisting of four pieces. The necessary elements are a pair of pillowcases, a duvet cover, and a sheet or a fitted sheet or a bed skirt. The fabric flattening and cutting machine used in the production of four-piece bedding sets is a special device used to flatten large pieces of fabric and then cut them into the required pieces in one go according to the set size. Its core function is to replace manual labor in completing the five processes of laying the fabric, straightening, flattening, setting the length and cutting.

[0003] However, existing fabric flattening and cutting machines for bedding set production typically use additional servo motors or cylinders to drive swing rollers to flatten the fabric and prevent it from springing back and shrinking. Over long periods of use, the added servo motors or cylinders increase the overall energy consumption of the equipment, thus increasing operating costs. Furthermore, the addition of servo motors or cylinders also increases the potential for equipment failure; a malfunction in the servo motor or cylinder driving the swing rollers may affect the normal operation of the equipment. Therefore, this does not meet the current requirements. To address this, we propose a new fabric flattening and cutting machine for bedding set production. Utility Model Content

[0004] The purpose of this utility model is to provide a fabric flattening and cutting machine for the production of four-piece bedding sets, in order to solve the problems mentioned in the background art. In general, existing fabric flattening and cutting machines for the production of four-piece bedding sets use an additional servo motor or cylinder to drive a swing roller to flatten the fabric in order to prevent the fabric from springing back and shrinking. During long-term use, the additional servo motor or cylinder will increase the overall energy consumption of the equipment, thereby increasing the operating cost of the equipment. In addition, the additional servo motor or cylinder will also increase the failure points of the equipment. When the servo motor or cylinder used to drive the swing roller fails, it may affect the normal operation of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric flattening and cutting machine for producing four-piece bedding sets, comprising a fabric cutting machine body, a metal shell fixedly installed on the upper end face of the upper end face of the fabric cutting machine body, a cutting cylinder fixedly installed on the upper side inside the metal shell, a strip plate connected to the piston rod of the cutting cylinder, and a slidable rod slidably installed on both sides of the lower end face of the strip plate, with an inclined pushing groove provided on the outer side of the bottom end of the inclined rod; The inclined rod has a spring groove inside, and the spring groove contains a spring. The lower end face of the spring is connected to a metal sleeve located inside the spring groove. The shaft of the metal sleeve is connected to a connecting rod, and the lower end face of the connecting rod is fixedly installed with a swing roller.

[0006] Preferably, the lower side of the front end face of the metal shell is provided with a fabric through hole that penetrates the metal shell, and the connecting rod and the swing roller are both located inside the fabric through hole.

[0007] Preferably, a cutting table is provided below the two swing rollers, and the cutting table is fixed to the upper end face of the fabric cutting machine body by bolts.

[0008] Preferably, a fabric cutting knife is fixedly installed at the middle position of the lower end face of the strip plate, and a cutting knife through hole is provided on the outer side of the bottom end of the fabric cutting knife, located at the middle position of the inner wall of the upper end of the fabric through hole.

[0009] Preferably, a control panel is fixedly installed on the outer surface of the fabric cutting machine body on one side of the metal shell, and the fabric cutting machine body and the cutting cylinder are electrically connected to the control panel.

[0010] Preferably, the outer surface of the inclined rod is in contact with the inner wall of the inclined pushing groove, and the inclined rod and the inclined pushing groove are slidably connected.

[0011] Preferably, a protective cover plate is provided above the cutting cylinder on the upper surface of the metal shell, and the metal shell and the protective cover plate are fixed together by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a cutting cylinder to drive a fabric cutting blade downwards for fabric cutting. Simultaneously, two inclined rods are pushed along an inclined push groove. As the inclined rods move along the groove, a swing roller connected to them via a connecting rod moves synchronously along the same trajectory. As the swing roller moves, its lower end face contacts the upper end face of the fabric before the fabric cutting blade and pulls it, thus straightening the fabric. This technical solution eliminates the need for an additional motor or cylinder to drive the swing roller for straightening, reducing equipment production costs while lowering energy consumption and failure rate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The main body 1 (model DC-500), cutting cylinder 5 (model SC-32), and spring 14 (model JX110) of the fabric cutting machine mentioned in this utility model can be obtained from the market or through private customization.

[0017] Please see Figures 1 to 4 An embodiment of this utility model is provided: a fabric flattening and cutting machine for producing four-piece bedding sets, including a fabric cutting machine body 1, a metal shell 2 fixedly installed on the upper end face of the upper end face of the fabric cutting machine body 1, a cutting cylinder 5 fixedly installed on the upper side inside the metal shell 2, a strip plate 6 connected to the piston rod of the cutting cylinder 5, and a diagonal rod 11 slidably installed on both sides of the lower end face of the strip plate 6, and an inclined pushing groove 12 is provided on the outer side of the bottom end of the diagonal rod 11; The inclined rod 11 has a spring groove 13 inside, and the spring groove 13 contains a spring 14. The lower end face of the spring 14 is connected to a metal sleeve 15 located inside the spring groove 13. The shaft of the metal sleeve 15 is connected to a connecting rod 8, and the lower end face of the connecting rod 8 is fixedly installed with a swing roller 9. The lower side of the front end face of the metal shell 2 has a fabric through hole 4 that penetrates the metal shell 2, and the connecting rod 8 and the swing roller 9 are both located inside the fabric through hole 4. A cutting table 10 is provided below the two swing rollers 9, and the cutting table 10 is fixed to the upper end face of the fabric cutting machine body 1 by bolts. A control panel 3 is fixedly installed on the outer surface of the fabric cutting machine body 1 on one side of the metal shell 2, and the fabric cutting machine body 1 and the cutting cylinder 5 are electrically connected to the control panel 3. The equipment can be controlled through the control panel 3. When the equipment is needed to cut the fabric, the fabric is passed through the fabric through hole 4. When the fabric that has passed through the fabric through hole 4 reaches the specified length, the cutting cylinder 5 is activated to push the strip plate 6 connected to it downward. As the strip plate 6 descends, the two inclined rods 11 that are slidably installed on the lower end face of the strip plate 6 will move inclined along the inclined push groove 12 located on the outer side of its bottom end. As the inclined rods 11 descend, the swing roller 9 connected to them through the connecting rod 8 will also move inclined. As the swing roller 9 moves inclined, it will gradually approach the fabric. When the lower end face of the swing roller 9 contacts the fabric, it will press and fix the fabric at the contact position between the swing roller 9 and the cutting table 10, and pull it to straighten the fabric. The above technical solution eliminates the need for an additional motor or cylinder to drive the swing roller 9 for straightening operations, thereby reducing equipment production costs and lowering energy consumption and failure rate.

[0018] A fabric cutting knife 7 is fixedly installed at the middle position of the lower end face of the strip plate 6, and a cutting knife through hole is provided on the outer side of the bottom end of the fabric cutting knife 7, which is located in the middle position of the upper inner wall of the fabric through hole 4; a metal sleeve 15 is fixedly sleeved on the outer surface of the top end of the connecting rod 8, and a spring 14 is connected to the upper end face of the metal sleeve 15. When the swing roller 9 contacts the fabric, but the inclined rod 11 is still being pushed, the spring 14 will be squeezed by the spring force of the spring 14. The spring 14 in the above technical solution can prevent the swing roller 9 that contacts the fabric from jamming the strip plate 6 that is indirectly connected to it, thereby preventing the fabric cutting knife 7 fixed to the lower end face of the strip plate 6 from moving downward to perform cutting operations. Once the fabric is stretched and fixed, it can be cut by the fabric cutting blade 7, which moves downward along with the strip plate 6. After the cutting operation is completed, the cutting cylinder 5 pulls the strip plate 6 upward. The upward movement of the strip plate 6 can gradually pull the fabric cutting knife 7 and the two swing rollers 9 back to their original positions. Once the fabric cutting knife 7 and the swing rollers 9 have returned to their original positions, the second cutting operation can be carried out.

[0019] The outer surface of the inclined rod 11 is in contact with the inner wall of the inclined push groove 12, and the inclined rod 11 and the inclined push groove 12 are slidably connected. This structure can ensure the stability of the inclined rod 11 moving along the inclined push groove 12, thereby preventing the inclined rod 11 and the swing roller 9 indirectly connected to it from shaking.

[0020] The cutting cylinder 5 is provided with a protective cover plate located on the upper end face of the metal shell 2, and the metal shell 2 and the protective cover plate are fixed together by screws; the protective cover plate can protect the cutting cylinder 5, and when the cutting cylinder 5 malfunctions, the protective cover plate can be removed to repair the cutting cylinder 5.

[0021] 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 illustrative 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
