[0004] Based on the above patent search and understanding of the application of slitting in the production of existing freezer sealing strips: the slitting operation may require manual positioning, which not only increases labor costs but also reduces production efficiency. In addition, manual operation may also introduce errors, further affecting the slitting effect. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a slitting device for the production of freezer sealing strips. This solves the problem that existing slitting operations may require manual positioning, which not only increases labor costs but also reduces production efficiency. Furthermore, manual operation may introduce errors, further affecting the slitting effect.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A slitting device for producing freezer sealing strips includes a support frame; a protective frame is fixedly installed at the top middle position of the support frame, a cylinder is fixedly installed at the upper inside of the protective frame, the bottom position of the cylinder is fixedly connected to the top middle position of a sliding member, the sliding member is slidably connected to the inside middle position of the protective frame, a detachable cutter is provided at the bottom middle position of the sliding member, and a conveyor belt is provided at the front and rear ends of the top of the support frame.

[0008] According to one embodiment of the present invention, the protective frame is located in the middle of the two conveyor belts, and the gap between the two conveyor belts is located directly below the cutter.

[0009] According to one embodiment of the present invention, a limiting frame is fixedly installed at the front and rear ends of the support frame, the two limiting frames are symmetrically designed, and each limiting frame is located directly above a conveyor belt.

[0010] According to one embodiment of the present invention, a motor is fixedly installed on the left side of each of the limiting frames, and the rotating shaft of each motor is fixedly connected to the left side of a bidirectional screw, which is located inside the lower part of the limiting frame.

[0011] According to one embodiment of the present invention, the bidirectional screw is provided with reverse threads on both sides of the middle position, and a clamping plate is slidably connected to the bottom left and right sides of the limiting frame. Each clamping plate has a threaded hole in the middle of its side, and the two sides of the bidirectional screw are respectively inserted into the threaded holes of a clamping plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The motor drives the bidirectional screw to rotate, and the reverse threads on both sides of the bidirectional screw bring the two clamping plates closer to each other, which can stably clamp and limit the sealing strips of different specifications. This effectively prevents the sealing strips from shifting or excessively deforming during the cutting process, ensuring the accuracy of the cutting position and reducing the generation of waste.

[0014] Because the spacing of the clamping plates can be adjusted by a bidirectional screw, the device can adapt to the cutting requirements of freezer sealing strips of different widths, thus expanding the applicability of the device.

[0015] The entire slitting process is automated by conveyor belts to transport the sealing strips, and cylinders drive the cutters for slitting. No manual positioning is required, resulting in a high degree of automation, reduced human intervention, improved slitting efficiency, and lower labor costs. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a slitting device for producing freezer sealing strips, including a support frame 1; a protective frame 101 is fixedly installed at the top middle position of the support frame 1, a cylinder 102 is fixedly installed at the upper position inside the protective frame 101, the bottom position of the cylinder 102 is fixedly connected to the top middle position of the sliding member 103, the sliding member 103 is slidably connected to the inner middle position of the protective frame 101, a detachable cutter 104 is provided at the bottom middle position of the sliding member 103, and a conveyor belt 105 is respectively provided at the front and rear ends of the top of the support frame 1.

[0029] The protective frame 101 is located in the middle of the two conveyor belts 105, and the gap between the two conveyor belts 105 is located directly below the cutter 104.

[0030] Among them, a limiting frame 2 is fixedly installed at the front and rear ends of the support frame 1, the two limiting frames 2 are symmetrically designed, and each limiting frame 2 is located directly above a conveyor belt 105.

[0031] Each limiting frame 2 has a motor 201 fixedly installed on its left side. The shaft of each motor 201 is fixedly connected to the left side of a bidirectional screw 202, which is located inside the lower part of the limiting frame 2.

[0032] The bidirectional screw 202 has reverse threads on both sides in the middle. The bottom left and right sides of the limit frame 2 are slidably connected to a clamping plate 203. Each clamping plate 203 has a threaded hole in the middle of its side. The two sides of the bidirectional screw 202 are respectively inserted into the threaded holes of a clamping plate 203.

[0033] When using:

[0034] First, start the two conveyor belts 105, then place the sealing strip at the top of the front conveyor belt 105 and convey it backward. When the sealing strip is cut to the position below the cutter 104, the conveyor belt 105 stops conveying and starts the motor 201 on the limit frame 2. The motor 201 drives the bidirectional screw 202 to rotate. The reverse threads on both sides of the bidirectional screw 202 cause the two clamping plates 203 to come closer to each other and clamp and limit the sealing strip conveyed by the two conveyor belts 105, so as to avoid the sealing strip from shifting during the cutting process and causing waste.

[0035] Next, cylinder 102 is activated, pushing the sliding member 103 to slide downward along the protective frame 101. The cutter 104 at the bottom of the sliding member 103 moves downward accordingly to cut the sealing strip. After the cutting is completed, cylinder 102 drives the cutter 104 to return to its original position.

[0036] The conveyor belt 105 continues to operate, transporting the slit sealing strips away and simultaneously transporting new sealing strips for the next slit operation. No manual intervention is required throughout the process, improving slit efficiency. If the cutter 104 is worn or needs to be replaced, it can be removed from the bottom of the sliding part 103 for replacement.
